Post comprises at least one entrance, preferably a plurality of radially path and one the entrance of post with The passage of fluid connection is provided between the liquid outlet. Entrance can be tangent with the center line of passage, post with Sleeve can be taper.

Liquid outlet preferably includes a nozzle and a plurality of exit passageway that forms in nozzle. In nozzle sets Can place potted component between the ring portion of part and the mid portion, leak to housing by ring portion to prevent liquid The outside.

In another embodiment, the invention provides a nozzle component, it has a housing, to have swing The nozzle of limiting member and one produces the member of swing. Housing have first end with a liquid inlet and Form second end of an opening. Nozzle assembly have a first end, a mid portion, one second end and One liquid conduits, first end form a sleeve that is arranged in the housing, and mid portion passes opening and stretches out, Second end has a liquid outlet, and conduit is in fluid connection between housing and liquid outlet. Nozzle sets The first end of part is positioned at the downstream of liquid inlet. The member that produces swing is placed in the housing, towards liquid The body entrance, and a post is arranged, this post extends from it, and engages with sleeve pine loose ground, preferably, post With sleeve all be taper.

In another embodiment, provide a nozzle component, the nozzle and that it has a housing, to have the swing limiting member produces the member of swing.Housing has one first end, one second end and a mobile path, and first end has a fluid inlet end, and second end has an opening, and flow passage extends between first end and second end.Nozzle assembly have the generation swing that is placed on first end in the housing, closes with first termination member, pass second end and a water passage that mid portion, swing limiting member such as oscillating deck, that opening stretches out have outlet nozzle, the swing limiting member engages with mid portion near opening, and water passage provides the fluid connection between flow passage and the outlet nozzle.

The member that produces swing is a swing turbine head preferably, and swing turbine head then forms conical surface, and it is tangential groove that the latter has the part of a plurality of fluid inlet end towards housing.In a preferred embodiment, the member that produces swing can be a swing turbine head, and it has a plurality of fins that radially extend, and described fin is positioned at the downstream of the liquid inlet of housing.The swing limiting member can be one to be contained in the ring on the fin.

One aspect of the present invention provides a kind of nozzle component that produces oscillating structural member or swing turbine that comprises, described generation oscillating structural member or swing turbine all make nozzle produce swing, and irrelevant with quantity, design or the configuration of nozzle inlet path.More particularly, the generation oscillating structural member does not rely on the tangential exit passageway on the nozzle.This makes that the outlet of nozzle can be designed in the following manner,, produces desirable jet flow width and figure that is, as is applicable to that the flower of usefulness spreads at home.

Another aspect of the present invention is for providing a kind of nozzle, it can comprise the exit passageway of any amount and any configuration, but preferably there is number few, and exit passageway, to prevent and the obstruction that produces by mineral deposit and particle aggregation with bigger inside dimension.Because nozzle is swung, so liquid distribution or covering from the teeth outwards is extremely uniform.Therefore, only need provide lip-deep with less exit passageway and cover fully, and under the situation of shower, obtain a kind of soft sensation.Owing to only need less path,, retrained or stop up by lime, other mineral matter or particle so that path is unlikely so each path can be widened.Preferably, path is enough wide, with by entering the common sand of fluid supply.

In addition, the invention provides a speed system, wherein, most of pressure through shower nozzle falls, and preferably is essentially all pressure and falls all and produce in a big hole, and this hole produces current that are directed to and are distributed to uncovered path downwards.This speed system is favourable to the weight that reduces mineral matter accumulation and minimizing shower nozzle and nozzle.Adopt speed system, just have less mineral matter to pile up, because exit passageway no longer relies on and has the long-pending opening of small bore the flow of water is divided into other current, thereby exit passageway can be widened or redesign.Adopt speed system, the weight of shower nozzle and nozzle is lighter, because nozzle is in the downstream of throttle orifice, thereby is not full of liquid when working.Nozzle would rather comprise a housing and the deflector in housing, with the water that leads and come out from throttle orifice.Weight saving is particularly advantageous in the swing shower nozzle, because the quality that reduces causes the proportional of angular momentum of nozzle to reduce, this angular momentum causes the nozzle housing vibration.Though as what provide among the figure that described just now and below, speed system preferably is used in combination with the member that generation described herein is swung, but, speed system also can use in conjunction with other swing mechanism, comprising the swing mechanism of U.S. Patent No. 5551635 and U.S. Patent No. 40073438, last patent is combined herein, with as a reference, back one patent is also combined herein, with as a reference.

Another aspect of the invention is provides a swing limiting member.The jet width of nozzle of the present invention is determined by the structure of the exit passageway in the nozzle and the deflection angle that acts on the nozzle simultaneously.For example, if nozzle provides one 6 ° jet width when using by fixed mode, swing then produces eccentric 5 a ° deflection angle, then according to the present invention, when pressing weave mode and use, effectively jet width will be about 16 ° (all have in all directions 5 ° additional width).Therefore, the swing limiting member effective jet width of determining nozzle and each liquid stream in swing once all play an important role during the scope in circular arc path of process.

Another aspect of the present invention is the member of a generation swing, and it is placed to nozzle component and directly engages or contact.Can be bonded on, remain on or be fixed on the nozzle assembly though produce the member of swing, will not produce preferably all usually that the member swung and nozzle assembly are made of one or fixed thereon with method for distinguishing.More more specifically, nozzle assembly has the end away from nozzle.Preferably, the member of the far-end of nozzle assembly and generation swing is admitted each other with the negative and positive relation of pine, particularly is easy to slide or swing into the place of suitable unrestricted relation at far-end and member.A particularly preferred layout is that columniform post (sun) is received within the columniform sleeve (the moon), and at this place, the external diameter of post is less than the internal diameter of sleeve.Another kind of scheme is, post can form a frusta-conical surface (sun), is received within the truncated cone shape sleeve (the moon), and at this place, the truncated cone angle of post is less than the truncated cone angle of sleeve.Will be appreciated that post can be the part of nozzle assembly, sleeve then can be a part that produces the member of swing, perhaps conversely.Preferably post is become to have betwixt enough tolerances with sleeve design, can be with respect to the nozzle assembly swing and can interlock so that produce the member of swing.In addition, most preferably, adopt the member of the generation swing of the post with taper or truncated cone shape, its first diameter is received within the taper or truncated cone shape sleeve of nozzle assembly.

The relation that produces the member of swing or swing turbine and the pine pine of a body for example advantage of post and the relation of sleeve is, swinging before turbine will begin to swing, has only very little frictional force or other power to overcome.Like this, the beginning of swing of the present invention with keep irrelevant with fluid flow basically, even and during much smaller than 2.5 gallons of per minutes of maximum of the legal provisions in many states, also can in shower head and tap, work very effectively at flow.

Second advantage of the relation of post and sleeve be, the swing turbine be easy to leave the axial centre of liquid inlet upright, be offset or tumble.In fact, also can stop with an angle of overturn through nozzle component, swing turbine even without liquid with respect to the longitudinal center line of liquid inlet.For the most effective swing is provided, the swing turbine preferably can be offset, and the longitudinal center line that leaves the liquid inlet is enough far away, so that most of liquid of sending through the liquid inlet only is directed in a side of swing turbine, in time towards any given position.Enough skews that the post of pine loose fit and the relation of sleeve make liquid discharge apparatus of the present invention obtain swinging turbine with less part in the fore-and-aft distance (distance from the liquid inlet to liquid outlet of central line measurement vertically) of much shorter.

Another aspect of the present invention is for providing one or more intermediate sleeves, and it is placed with the relation of aforesaid post and sleeve.Nozzle assembly for having a post, sleeve and one or more intermediate sleeve preferably makes the relation between each member (post, sleeve and intermediate sleeve) guarantee to have swing therebetween.

Another aspect of the present invention is for providing the flow passage of fully opening in whole nozzle component, so that the throttling of limited flow can be a flow control loop and just in the size of the aperture of the upstream of the exit passageway of nozzle, this control loop is arranged in the nozzle component, near the liquid inlet.Like this, in housing, keep appropriate pressure,, then produce suitable water speed, so that a satisfied shower to be provided at liquid outlet to drive the swing turbine.

Another aspect of the present invention is for providing a nozzle component, and it has the pin in the exit passageway that is contained in nozzle.The swing of shower nozzle and power make pin rotation or vibration, contact with the inner surface of path, thereby have eliminated any possibility that mineral matter is piled up.Pin preferably has a head and a bar that is constrained in the nozzle, and it is fixed on the stem knob and passes exit passageway and stretch out.Importantly, stem knob and bar are not blocked flowing through the liquid of exit passageway.

Will be appreciated that, shower nozzle of the present invention with and each part can use known materials manufacturing arbitrarily, these materials anti-chemical attack and thermal shock from its liquid that passes through.At liquid is the place of water, and preferable material comprises plastics such as polytetrafluoroethylene (PTFE) and metal or alloy such as stainless steel.Other material that is suitable for using in the present invention all is clearly to the person skilled in the art, and thinks all within the scope of the invention.

Fig. 1 is the cutaway view of nozzle component 40.Nozzle component 40 is useful on the housing 42 that keeps a swing turbine 44 and an oscillating deck 46.Housing 42 forms a watertight substantially chamber 43, and it has the inlet 45 of the upstream that is positioned at swing turbine 44.The bottom surface 50 of housing 42 forms a ring, hole or openings 52, is used to pass it and admits one 54 slidably, and the latter is fixed in housing 42 on the oscillating deck 46, in the fixed outside of housing 42 on nozzle 48.Axle 54 with lip seal 56 sealings, leaks from housing to prevent water in hole 52, and permission axle 54 is tumbled in opening 52 and rotated again simultaneously.Also can adopt O shape circle seal shaft 54 in opening.

Swing turbine 44 has the upper surface 58 and of taper to be roughly columniform sleeve 62, and upper surface forms many non-paths 60 (also can referring to Fig. 4) radially.The upper surface 58 of swing turbine 44 is preferably crossed sleeve 62 and is stretched out, and overhangs 64 to form an annular that faces down end 62.The sleeve 62 of swing turbine has the inner surface 68 that marks an internal diameter, and this internal diameter is greater than the external diameter of axle 54.After assembling, sleeve 62 slides in the outside of axle or post 54, and swing turbine 44 then rests on the top of axle 54.

Oscillating deck 46 has a bottom surface 72, and it upwards leaves 50 one-tenth gradients in bottom surface of housing 42.The angle that forms between oscillating deck 46 and the bottom surface 50 has been determined the full swing angle that nozzle 48 is experienced by tumbling of limits nozzle assembly.When the center line of nozzle assembly alignd with the center line of housing, the bottom surface of oscillating deck 72 preferably forms about one 1 degree and the angle between about 20 degree with the bottom surfaces 50 of housing 42, and was more better about 2 degree and between about 10 degree, better again 4 spend about.Tumbling of nozzle will be restricted with the angle between aforementioned panels and the housing equally, causes the factor with the twice angle, just strengthens the effective jet width that increases shower nozzle with same angle in all directions.

Axle or post 54 provide a passage 74, and it is in fluid connection with the inlet 76 and the nozzle 48 of axle.Inlet 76 preferably passes a plurality of paths that the walls of post extend, preferably from the top of housing 42 downwards at angle towards the bottom surface of housing 42.Passage 74 comprises a speed pipe 75, it according to the water saving standard for example 2.5 gallons of per minutes (GPM) restrictions through the fluid flow of shower nozzle.So passage 74 is just opened, with 78 one-tenth fluid connections of output channel of nozzle 48.

Therefore, liquid is followed such paths, promptly through inlet 45 inlet chambers 43, crosses swing turbine 44, enters the passages 74 of axle in 54 through inlet 76, and through with axle 54 in the passage 48 injection path 78 that is communicated with of doing to flow from nozzle 48, come out.In when work, there is the fluid supply of pressure to be communicated with inlet in the housing.Turbine is owing to the liquid that impacts at the upper surface of swinging turbine is swung.Swing is meant that mainly the swing turbine tumbles and make circular motion to a side and around the central axis of axle, so that does rolling near the inner surface of the lower end of swing turbine with the outer surface of axle and contact.The swing of swing turbine acts on that the axle effect of going up is strong, and these power are reached on the oscillating deck by axle, so that the bottom surface of oscillating deck is done rolling with the bottom surface of housing and contacted.The swing of the same response axis of nozzle and swinging.In case the chamber is full of water substantially, water wherein just enters the inlet in the axle, and flow to nozzle through the passage in the axle.

Fig. 4 is the cutaway view of shower nozzle 40 along the 4-4 line of Fig. 1.The end face 58 of swing turbine 44 has the groove 60 that forms by non-radial configuration when illustrating.Should be understood that, the liquid flow of impact on swing turbine 44 will push into the position of tumbling with swing turbine 44 to the next door, so that the mid point of swinging turbine 44 is substantially in the outside from the liquid stream of inlet 45, and has only a side of swing turbine 44 in time to align with liquid stream in any position.Path that on the upper end 58 of swing turbine 44, forms or each of groove 60 all right and wrong radially and play a part fin, these fins make the swing turbine make circular motion around the liquid inlet when liquid is flowed through groove.The relation of pine pine between non-radial slot 60, conical surface 58 and sleeve 62 and the post 54 guarantees that mobile with pressure when liquid, when facing toward the top of swing turbine 44, swing turbine 44 will be tumbled, and depart from the center, and begin swing.More more specifically, the liquid that impacts on the conical surface 58 of turbine 44 produces the power 31 of tumbling, and the liquid of process groove 60 then produces revolving force 33.Therefore, the liquid stream through inlet 45 makes swing turbine 44 as swinging with clockwise direction shown in the arrow 61.In case swing beginning, continuous current keep swing turbine 44 to be in weave mode.In addition, flowing of liquid also produces a downward confining force, and it pushes away downwards on turbine, tries hard to make turbine not move from the cooperative relationship of itself and nozzle assembly.Therefore, preferably make the angle of conical surface 58 enough big, even so that when turbine is tumbled fully, also produce at least one little power of tumbling, but angle do not behave like this greatly, up drawn and disengaged to cause turbine with nozzle assembly.

For given swing turbine, rate of oscillation or swing speed can increase (or reducing) through the flow of the liquid of shower nozzle by strengthening (or reducing).But,, might design the swing turbine, make it very fast or slower rate of oscillation by angle or the gradient that changes the groove in the swing turbine for a given fluid flow.Referring to Figure 12, a swing turbine can promptly design groove 162 and the swing turbine is designed to usually slower rate of oscillation by the little angle β that leaves radially by reducing the gradient of groove.Equally, the swing turbine also can promptly design grooves 164 and the swing turbine has been designed to rate of oscillation faster by the bigger angle of leaving radially 6 by the gradient of oversized slots.Return the past referring to Fig. 4, groove even can be designed to have the angle of variation is to form the circle of pinwheel type.In addition, the number of groove and size also can be modified as a rate of oscillation customized.

Figure 17 A～17I is a schematic diagram, and they show according to the swing turbine sleeve 62 of the shower nozzle 40 of Fig. 1 and the swing between the nozzle assembly post 54.From tumbling to the turbine sleeve 62 and post 54 on housing 42 the right, turbine sleeve 62 and post 54 are made circular motion clockwise around housing mid point 69, and what illustrate is by 45 increments of spending between each figure herein.Because post 54 and turbine sleeve 62 are always tumbled along same direction, so their mid point separately 71,73 radially aligns with the mid point of housing 69 basically.Because turbine sleeve 62 clockwise directions (as shown around the motion of housing mid point 69 by turbine mid point 71) are made circular motion, so sleeve 62 forces post 54 to be tumbled and makes circular motion along same clockwise direction (mid point as post is shown around the motion of housing mid point 69).

Go back simply referring to Fig. 1, turbine 44 contacts with post 54 in three places with turbine sleeve 62: the lower internal edge of (1) sleeve 62, along the direction (promptly to Fig. 1 the right) of tumbling; (2), leave the direction of tumbling (promptly to Fig. 1 the left side) near the interior location of the upper end of sleeve 62; (3) at the downside of turbine.Because three contact points are arranged, therefore need one or more points and slide, so that the turbine swing.Though it is all moistening by liquid such as water that institute has point of contact, the long-term use meeting of turbine is producing some boundary wear on the post or on the inner surface of sleeve.

Figure 10 A～10I is a schematic diagram, and they illustrate the swing between oscillating deck of the present invention and the housing bottom surface.Because the angle that forms between oscillating deck and bottom surface, oscillating deck contact circle and marks one have first of diameter 47 (and girth) and justify on oscillating deck 46 with rolling between the bottom surface, and this diameter is different from second diameter of a circle 51 on the bottom surface 50 of housing 42.In order to keep and the contacting of bottom surface, what oscillating deck must be by the rotation compensation girth is poor.As shown in the figure, if circle 47 diameter less than the diameter of circle 51, then when fricton-tight (between oscillating deck and bottom surface) oscillating deck 46 will be along the direction rotation (as with arrow 140 shown in) opposite with swing (as with shown in the arrow 142).Each follow-up view is represented the clockwise swing of one 45 degree among Figure 10 A～10I.

In Figure 10 A, swing is tumbled downwards with the post (not shown) and to be begun on paper, so that first circle 47 of oscillating deck is pushed over, contacts with the circle 51 of bottom surface 50.For the purpose of illustrating, on oscillating deck 46 and bottom surface 50, near the contact starting point between the circle 47,51, two triangular markers 144,146 have been put respectively.When swing from but contact point is clockwise when mobile, oscillating deck experiences a little counterclockwise rotation.For the known diameter shown in Figure 10 A～10I 47,51, it seems whole when once swinging that oscillating deck 46 is in opposite direction around 1/4th circle rotations, so that a ratio that is about 4 swing and rotation to be provided.Rotation is the rightabout along swing in this example, because the diameter of circle 47 and girth (are D less than diameter and the girth of justifying 51 ₃＞D ₄).It should also be appreciated that bottom surface itself can be a truncated cone shape.Will be appreciated that the swing and the ratio of rotation can strengthen by a bigger oscillating deck and diameter difference or the differential seat angle between the bottom surface are provided.For oscillating deck and bottom surface, the dominant force swing of mentioning just now also is applicable to member or swing turbine and the post that produces swing with the principle of the ratio of rotation.

Return and to see Fig. 1 in the past, post 54 is by two intermediate sleeves 80,82 (use of intermediate sleeve is chosen wantonly) encirclement, they have greater than axle 54 but less than the diameter of the sleeve 62 of swing

turbine 44.Sleeve

80,82 is being swung (tumble and rotate around axle) when contact with the inner surface 66 of swing turbine 44.Additional with sleeve, the swing turbine is tumbled to desired angle, between each surface, keep little contact angle simultaneously again.

Post or axle 54 also comprise a carrying path 84, and it feeds in the annular cup 86 of nozzle 48 near opening 52.Carrying path 84 is caught and anyly may around the opening and do not adopted the water that leaks under the situation of sealing.Vacuum by the water generates of coming out from exit passageway 78 is passed through water carrying paths 84 suction passages 74 from cup 86.Path 84 also is conducted to air in the space below the speed pipe 75, thereby makes the current that come out from speed pipe 75 can keep its speed, is deflected again and guides to downwards in the path 78 simultaneously.

Fig. 2 is the cutaway view of second embodiment of nozzle component.Shower nozzle 90A is basic identical with the shower nozzle 40 of Fig. 1, just produces the difference that concerns between member of swinging or the far-end 94 of the swinging turbine 92 and nozzle assembly.According to the discussion of front, swing turbine 92 comprises a post 96, rather than a sleeve, and far-end 94 then comprises a sleeve 98, rather than a post.In addition, post 96 and sleeve 98 show the use of frusta-conical surface 100 and 102 respectively.They are preferably having a common fulcrum 104 somewhere along center line.As the swing turbine 44 that adopts the front, from the liquid stream shock surface 58 of inlet 45, and will swing turbine 92 and tumble to a side, come in contact until surface 100,102.The liquid stream of the groove 60 of one side of process turbine effect one tangential force (described as pressing Fig. 4) on swing turbine 92 is swung the swing turbine in sleeve 94.Compared with in the configuration of shower nozzle 40, the rolling component of swing can more easily find out in the configuration of shower nozzle 90, and this may be because contacting between turbine post 96 and the sleeve 98 is essentially a straight line, rather than 3 shown contacts of the turbine 44 of Fig. 1.

Figure 18 A～18I has schematically represented according to the swing turbine post 96 of the shower nozzle 90A of Fig. 2 and the swing between the nozzle assembly sleeve 98.Because at the diameter of the circle 59 that forms on the surface of turbine post 96 diameter, so when turbine post 96 clockwise swings, will rotate in the counterclockwise direction with the turbine post 96 of Figure 61 example less than the circle 61 that on the surface of relative sleeve 98, forms.Shower nozzle 90A preferably has precedence over shower nozzle 40 and selects, because it has been eliminated and 3 wearing and tearing that contact is relevant.Can think that the minimizing of wearing and tearing is synthesis result of eliminating rotation (is counterclockwise for the clockwise swing) coupling of 3 rotations that contact and make nozzle assembly (as shown in Figure 10 A～10I, being counterclockwise to clockwise swing) and turbine.Because post 96 and sleeve 98 rotate along same direction, may eliminate so amount of friction therebetween significantly reduces maybe.Though shower nozzle 90 has post 96 and the sleeve 98 with most preferred frusta-conical surface when illustrating, also be suitable for post 96 and sleeve 98 made and have simple cylindrical surface.

Fig. 3 is the cutaway view of the shower nozzle of Fig. 2, and it has two improved characteristics.At first, shower nozzle 90B is furnished with a nozzle assembly with light-wall pipe 110B, and this light-wall pipe is engaged to oscillating deck 46 on the nozzle 48.The very bold material of the preferential usefulness of light-wall pipe is preferably the metal manufacturing as the stainless steel, so that reduce to manage the external diameter (comparing with the pipe 110A among Fig. 2) of 110B.For example, pipe can comprise that one has the stainless steel tube of about 0.15 inch internal diameter and about 0.18 inch external diameter.Reduce the external diameter of pipe 110B, just reduced the size of the upset or the needed power of nozzle assembly of tumbling.

Secondly, shower nozzle 90B has one or more bypass paths or groove 112 when illustrating, with deflection part liquid stream around turbine 60.Bypass path 112 is wished to reduce by water and is acted on power on the turbine, thus will act between turbine and the nozzle assembly and nozzle assembly and bottom surface or analog between power to be reduced to its size be that required power is swung in maintenance reliably.Can think that unnecessarily big power can cause the abrasion between each moving link of shower nozzle to strengthen, and produces noise.

Fig. 5 is the bottom view of shower nozzle, and it shows the outlet of nozzle.Though exit passageway can be by any way setting well known in the prior art,, preferred exit passageway group 78 is to be limited by a plurality of fins 79 that link to each other with deflector 77.The main application of deflector 77 is for providing the path of a bending to the water that flows through nozzle.Preferably sub-fraction exit passageway 77 is guided on 48 the axis of nozzle, so that provide jet graphics or covering uniformly in the outside that an object for example carries out the people of shower that closely is in of leaving shower nozzle with less angle.Less exit passageway angle 78a is preferably around the circumference of nozzle or radially inwardly forming with the spacing that separates towards each place of the medial axis (not shown) of nozzle.

Fig. 6 is the cutaway view of nozzle component 120, wherein, same numeral flag with the similar elements of the embodiment of the front shown in Fig. 2.Entry 76 in the post 54 extends in the passage 74, forms an angle tangent with the central axis of post 54 and passage 74, and liquid is circled round.Liquid 122 that circle round or the one-tenth helix arrives nozzles 124 through passages 74.Because the liquid that circles round to extrapolation, leans against liquid on the wall of passage 74 and nozzle 124, therefore do not need deflector.Nozzle preferably still comprises fin 79, reducing or eliminating circling round of liquid, and limits many liquid streams that come out from nozzle.Preferably fin is set for and made liquid to become 5 ° angle to go out with the central shaft of post.

Fig. 7 shows the cutaway view according to the another kind of shower nozzle 130 of preferred embodiment structure of the present invention and work, wherein, same numeral flag with the similar elements of the embodiment of the front shown in Fig. 2.Shower nozzle 130 has a nozzle 132, and the latter is with the pin 134 that is arranged in exit passageway 136.It is straight bar substantially that pin 134 has head and at one end, and head is positioned at chamber or passage 138 the insides, and bar extends downwards, enters or pass exit passageway 136.The centrifugal force that is produced by the nozzle of swinging makes the side of pin friction exit passageway 136 and keeps it not have lime or other mineral deposit.This is very useful from safeguarding that characteristic has high lime or other mineral concentration and requirement at water with the area of the shower nozzle that pressure is arranged.

Fig. 8 A～8D is the inhomogeneity graphic representation of the jet graphics that comes out from four shower nozzles with a distance of leaving shower nozzle, and these four shower nozzles comprise three shower heads that can obtain from the market (Fig. 8 A～8C) and a shower head (Fig. 8 D) of making according to Fig. 2 of the present invention.Fig. 9 A～9D is the similar figure with four same shower head preparations, but leaves bigger distance.In the shower nozzle each all is connected with the water source of constant pressure and guides one substantially down into and arrange the glass tube that the diameter about 1/4 inch is arranged.The result of this test illustrates as the side view that is collected in the liquid in the glass tube in the drawings.Obviously, the result shown in Fig. 8 D and the 9D provides the most uniform distribution of water along the width of jet graphics.Other figure then illustrates, the transmission of water have concentrate on jet graphics a bit or the trend in little subarea.

Figure 11 A and 11B are the diagrammatic side view of the figure of the water that sends according to the shower nozzle 40 of Fig. 2 with by nozzle 48.If it is fixing that nozzle 48 is controlled into, then the jet width of being demarcated by dotted line 150 will obtain the result according to the design of nozzle itself.When allowing nozzle 48 to swing according to the present invention, then jet width strengthens 2 α, wherein α be with oscillating deck and bottom surface (see figure 2) between the identical angle of angle.Figure 11 also shows the distinctive jet graphics that can with the naked eye see.The quick swing of nozzle 48 is broken single drop or liquid stream and is scattered along a circular arc path.For example, suppose that nozzle has 12 exit passageways: three exit passageway 78a are directed for 2 ° to depart from the center, and nine paths then are directed for 6 ° to depart from the center.If shower nozzle is designed to 2 ° swing ,-2 ° angle promptly is set between oscillating deck and bottom surface, then can obtain a jet angle (being the angle between the dotted line 150) that is total up to 16 °.Because 2 ° throw will provide 4 ° deflection (being 2 ° in all directions promptly), so three will be left the angle atomizing of liquids of 0 °～8 ° in axis with covering with 2 ° of exit passageways that are directed, it represents 1/4th zone of shower nozzle, and nine will be to cover 8 °～16 ° angle atomizing of liquids with 6 ° of exit passageways that are directed, and this is 3/4ths of an inlet zone.Should be pointed out that according to the present invention, can adopt the design of the layout of many other exit passageways.

Figure 13 is the cutaway view according to another nozzle component 160 of preferred embodiment structure of the present invention and work, wherein, same numeral flag with the similar elements of the embodiment of the front shown in Fig. 2.Nozzle component 160 has a housing 42, and it is used to keep a swing turbine 44 and an oscillating deck 46.Housing 42 forms a Room 43, and it has an inlet 45 that is positioned at the upstream of swing turbine 44.The bottom surface 50 of housing 42 forms one from its hole passed or opening 52, and it is used for being received in slidably the axle 54 that is fixed in the housing 42 on the oscillating deck 46 and at the nozzle (not shown) of the outside of housing 42.Axle 54 with lip seal 56 sealings, leaks from housing to prevent water in hole 52, and permission axle 54 is tumbled in opening 52 and rotated again simultaneously.Also can enclose seal shaft 54 in opening with an O shape.Should be pointed out that among described herein all embodiment, opening 52 is all enough wide, rotate and swing around the center line of housing to allow axle, thereby can produce described swing.Though housing 42 is leakage liquid not basically preferably, also can between axle 54 and opening 52 some fluid passages be set in advance, and this also within the scope of the invention.

Swing turbine 44 has the upper surface 58 of a taper, and the latter has a plurality of fins that extend radially 165 and is roughly columniform sleeve 62.Fin 165 is preferably done the sloping downwards and towards the center line of turbine 44, is similar to propeller.Fin 165 and do surface 167 1 sloping or truncated cone shape and work makes the swing turbine swing the groove of the swing turbine shown in extraordinary image Fig. 2 when contact with current.In order to limit the degree of swing, be provided with a swing limiting element 166, it can be the ring that the round edge around fin 165 is as shown in the figure installed, or the end of each fin 165 can so form, so that they are shown in Figure 15 and 16, towards the upstream.The tumble degree of restriction swing turbine on axle that act as of swing limiting element 166 is to obtain and the similar result of above-mentioned oscillating deck.Swing limiting element 166 is preferably formed as a frusta-conical surface 169, the latter is what fall with respect to frusta-conical surface 167, even so that when turbine 44 swings, the passage that is limited between surface 167,169 also is forced to align with the liquid that enters housing 42 from spout 171.For example, if turbine 44 is in vertical substantially position, then will pushes surface 167 to and turbine 44 is tumbled to the side through the liquid of spout 171.But, when turbine 44 is tumbled enough greatly, so that the surface 169 of swing limiting member 166 is when being admitted to liquid stream through spout 171, liquid is just pushed surface 167 to.Surface 167,169 preferred design become to have enough angles and surface area, so that tumbling of turbine is restricted.Will be appreciated that fin 165 can exactly radially (as shown in figure 14) or a certain angle extension of Off-Radial between surface 167,169.Fin with angle of bigger Off-Radial can be designed to promote turbine exactly by desired track, and does not have the tumble dependence of degree of this heavy restriction on orbit ring, perhaps is any dependence.In addition, making groove or ridge on the surface 167 of orbit ring, so that strengthen the relevant power that acts on the orbit ring, is useful.

Swing turbine 44 is preferably formed as a plurality of openings 168, and they make fluid connection with the passage 74 on the axle 54.The sleeve 62 of swing turbine has an inner surface 68 that limits an internal diameter, and this internal diameter is greater than the external diameter of axle 54.After assembling, sleeve 62 slides in the outside of axle 54, and swing turbine 44 then rests on the top of axle 54.Swing turbine 44 and axle 54 can be with teflon or the manufacturing of other suitable polymers material, to consider between swing turbine 44 and axle 54 some frictions being arranged and swing turbine 44 can freely be moved around axle 54.Fin can replace previously described oscillating deck in fact, and this is due to the fact that, i.e. ring compensation and the oscillating quantity that Control Shaft and nozzle stood.Swing in this embodiment with top described in Figure 10 A～10I be identical.

(a) change or control the motion of nozzle assembly to certain combination of (b).

Figure 21 is the side sectional view of nozzle component 200, and it has flow ring speed control system.Term used herein " flow ring speed control system " refers to the shower nozzle with flow throttling ring 202, the downstream that this ring is placed on inlet valve 204 and produces the member 92 (promptly swinging turbine) of swing, but in the upstream of jet expansion path 78.Shrink aperture when flow throttling ring 202 is designed to increase by pressure in the chamber and keep the more constant fluid flow that passes through its central small hole.Other details and the structure of flow throttling ring are described in U.S. Patent No. 4457343 and 4508144, and they are mentioned herein, with as a reference.

By flow throttling ring 202 being placed on the downstream of the member 92 that produces motion, the fluid flow that is sent out through nozzle 48 remains on the given level, liquid velocity and pressure independent in the basic and chamber 43.Place a needle-valve 204 that cooperates with valve seat 206, so that produce a throttling, it produces pressure and falls in chamber 43, and improves the speed that acts on the fluid in the member 92 that produces motion.Like this, member 92 (turbine) can be made by high-speed motion (swing), no matter pressure how in the chamber.In addition, when little fluid flow, needle-valve can be by restraining (promptly part be closed), so that keep good motion or swing speed.Should be pointed out that when the pressure of chamber is higher a less effective inlet opening must be arranged,, make member 92 by high-speed motion so that produce enough liquid velocities.For family's shower, preferred flow ring has a diameter to be about 0.128 inch hole, and can use with an outlet 208, and this Guan Youyi is greater than about 0.130 inch best about 0.140 inch diameter.

According to the present invention, the major advantage of flow ring speed control system is, it can be used to leave the impact control of the liquid of nozzle.As mentioned above, when pressure in the chamber strengthened, flow ring aperture diminished, and the liquid stream that causes passing it has bigger speed.In traditional shower head, the flow ring must be placed on the porch of chamber, and has eliminated any benefit of high velocity stream in the chamber, and this is because the liquid velocity that leaves nozzle is determined by jet expansion.In flow ring speed control system of the present invention, spray the exit passageway in the housing and the flow of uncontrolled liquid, this be because, the set cross-sectional area specific discharge ring of individual channel or speed pipe much bigger.Therefore, enter the high-speed liquid deflector guiding of spraying housing through the inflow-rate of water turbine ring, and from exit passageway, to come out at a high speed, without any great restraining.Its result is, can keep a constant flow velocity, allows the user to select the injection of little impact or large impact again simultaneously.

When needle-valve 204 is taken one's seat (closing) fully, there is not fluid through nozzle.When needle-valve slightly is opened, when for example the handle 210 that is contained in the cam 212 on the needle-valve 204 by rotating band was opened, liquid was with the high speed that produces high swing speed and produce the low pressure inlet chamber 43 that soft swing is sprayed.When needle-valve 204 further was opened, pressure in the chamber 43 strengthened, and the flow ring is shunk and bigger speed and bigger ram-jet are provided.The member that produces motion can at random be decelerated or stops by further opening valve 204 or opening bypass around the member that produces motion, and last situation produces low velocity, and then a situation then produces one even bigger impingement flow.Soft injection and large impact injection all provide liquid flow according to the rated value of flow ring 202.

1234,1236,1238 are shown in the cutaway view.In a preferred embodiment, each of

element

1234,1236,1238 all has same part, therefore only describes an element 1234 herein in detail.

This multi-nozzle assembly 1232 provides with fluid supply through each the fluid connection of inlet 1233 to

element

1234,1236,1238 by liquid distribution passage or chamber 1241 are set, these chamber 1241 enough spaciousnesses there is no throttling, in order to avoid before liquid arrives each element, in liquid, produce big pressure and fall.Chamber 1241 is made fluid connection by each liquid inlet 1248 to each element with each element, and this inlet is towards swing turbine guiding liquids.After liquid was through the swing turbine, it was re-oriented and enters oscillating nozzle 1256 also through it.

Each element 1234 all is useful on the housing 1240 that keeps the swing turbine.Housing 1240 forms wall or a track 1246 adjacent with liquid inlet 1248, and this inlet is positioned at the upstream of swing turbine 1242.Ring, hole or opening 1252 that the bottom surface of housing 1240 or far-end 1250 forms is one that pass from it, be used for admitting slidably post 1256, this post is preferably on the body 1254 that is fixed on swing turbine 1242 in the housing 1240.Post 1256 and body 1254 are provided for liquid is delivered to from housing 1240 fluid passage of nozzle opening 1266.Post 1254 usefulness one annular shoulder 1258 is held in the swing relation in opening 1252.This shoulder allows post 1254 to rotate in opening 1252.One ring, O shape are enclosed or are supported 1260 and can randomly be placed between the far-end of annular shoulder 1258 and housing 1240.According to this configuration, a part of cylindrical side wall of swing turbine 1242 can be along the inwall 1246 of housing 1240 along track travel.

Though each housing on the multicomponent assembly all must form the swing limiting member of track or certain type, also can be like this, promptly assembly 1232 can be opened the fluid connection between each element after liquid is through inlet 1248.Like this, the major part of assembly 1232 comprises: (a). one have periphery wall dish, a bottom surface and pass many rings 1252 of bottom surface, (b). a plurality of swing turbines, each swing turbine all has and passes the nozzle that a ring portion is stretched out, (c). a liquid distribution header, it provides the fluid injector that aligns with each ring portion, (d). be used for the swing limiting member of each swing turbine.In the embodiment shown, house steward forms with the liquid distribution plate of the top, bottom surface that is fixed on dish, and the liquid distribution plate has a plurality of inlets that align with ring portion.In addition, the swing limiting member is used in the wall that extends between the bottom of the bottom surface of dish and liquid distribution plate and forms, though, for wall, for prevent between each housing flow or even the regulation of crossing the swing limiting member stretch out, it is not necessary.

For each element, turbine body 1254 has a liquid inlet 1264 and a passage 1262, and the latter provides the inside of housing 1240 and the fluid connection between the fluid injector outlet 1266.Preferably, the turbine body comprises a plurality of access roades 1264, and the wall that the latter passes post extends, preferably radially towards the center line of post.

Therefore, liquid is followed such path, promptly through inlet 1233 access arrangements, enter housing 1240 through inlet 1248, through swing turbine 1242, through inlet 1264 passages 1262 that enter in the turbine body 1254, and leave nozzle 1256 through the liquid outlet 1266 of making fluid connection with passage 1262.Liquid outlet 1266 can be simple outlet as shown in the figure or a plurality of mouthfuls (in the Figure 59) that includes same or different angles.

When work, there are the fluid supply of pressure and the inlet 1233 in the equipment 1232 to make fluid connection.The pressure of the water of access arrangement makes water flow to each swing turbine 1242 through each inlet 1248.Water is active force on turbine 1242, down pushes away body 1254 and makes turbine 1242 owing to the liquid of the upper surface that flows through swing turbine 1242 is swung.In case housing 1240 is filled water substantially, water wherein just enters the inlet 1246 in the post and flow to outlet 1266 in the nozzle through the passage 1262 in the post.This design is particularly useful in hand-held injection apparatus, but also can be used in the device that is contained on the wall.Though device can have the nozzle of any amount, preferred device comprises 7～12 nozzles, will be appreciated that, removes and shares beyond the common fluid supply, and each element or swing turbine are worked independently of one another.

Figure 64 is the cutaway view of equipment 1270 of the present invention.Equipment 1270 has a housing 1272 that is used to keep a swing turbine 1274.Housing 1272 forms a chamber 1276 with an inlet 1278, and inlet is positioned at the upstream of swing turbine 1274.That the bottom surface 1280 of housing 1272 forms is one that pass from it, be used for admitting slidably post 1284 and at ring, hole or the opening 1282 of the nozzle of the outside of housing 1272, this post is fixed in housing 1272 on the swing turbine 1274.Post 1284 usefulness one annular shoulder 1288 is retained the swing relation in opening 1282.This shoulder permission post 1284 is tumbled in opening 1282 and is rotated.The wall type that this embodiment had adopted with Figure 63 and similarly limited swing, produced rotation contacts, the just extension socket of post 1284 rather than turbine itself contact, simultaneously, this wall inwardly stretches out and forms a contact surface 1285, as friction or the pliable and tough surface of height of a picture O shape circle or other suitable structure.

Swing turbine 1274 has a cone-shaped upper surface and similar to the swing turbine shown in Figure 60.Post 1284 is arranged on the passage 1290 of making fluid connection between liquid inlet 1292 and the nozzle 1286.Should be pointed out that special swing turbine 1274 shown here is not restricted, but can adopt any swing shown here turbine/post configuration.

Nozzle 1286 has one to do the hyperbaric chamber 1294 of fluid connection with passage 1290 and a plurality of high-pressure outlet path 1296.Hyperbaric chamber 1294 limits one and makes the opening 1298 of fluid connection with low-pressure chamber 1300.Low-pressure chamber 1300 has low tension outlet path 1302.Part current are 1294 arrival low-pressure chambers 1300 through the hyperbaric chamber, and at this place, it leaves nozzle with the pressure lower than the water that leaves the hyperbaric chamber, thereby forms big drop.The water that leaves high-pressure outlet path 1296 forms than leaving the little drop of low tension outlet path 1302.

Therefore, liquid is followed such path, promptly through inlet 1278 inlet chambers 1276, through swing turbine 1274, through inlet 1292 passages 1290 that enter in the post 1284.Liquid just leaves nozzle 1286 through high-pressure outlet path 1296 or low tension outlet path 1302 later on.In when work, there is the fluid supply of pressure to be communicated with inlet 1278 in the housing 1272.Pressure active force on post 1284 from the water that enters housing 1272 pushes away post 1284 downwards, and makes the turbine swing.Turbine 1274 is owing to the liquid of the upper surface that flows through swing turbine 1274 is swung.In case the chamber is filled water substantially, water wherein just enters the inlet in the post and flow to exit passageway in the nozzle through the passage in the post.This design provides one to be used to have a bath or particularly useful when the low pressure of the overall spray uniformly of analogue and high pressure drop producing with High-Pressure Water.Low speed, big drop help to eliminate the sensation of any pulse of high pressure drop, because they are not synchronous with the high pressure drop.

Figure 65,65A and 66 are two kinds of other cutaway views of connected structure, and they can be used for being used as power with the rotation of motor output shaft or nozzle assembly 1164 motion of spiraling, and go to rotate respectively one with this motion and have the gear or the axle of rotation accurately.In Figure 65 and 66, housing 1158, swing turbine 1160 and nozzle assembly 1164 are identical with the equipment 1157 of Figure 60 basically, and therefore, same reference number is used to draw levies similar elements.Motor 1310 and 1330 difference, equipment 1157 all is modified into the additional member that is contained on the nozzle assembly 1164, to replace nozzle 1174 and to be contained in additional member on the bottom surface of housing 1158.

In Figure 65, nozzle assembly 1164 has the post 1312 that stretches out, the latter and " universal " shape connector engages, and this joint provides at least two frees degree that can adapt to the swing of nozzle assembly 1164.Pin 1314 passes the engage sides of post 1312 swingably, or by another kind of scheme, is contained in swingably on the side of post 1312.The outermost end of pin 1314 engages with an annular ring 1316 with double-vane plate 1318 swingably, and wing plate extends radially from ring.Wing plate 1318 engages with another annular ring 1320 again swingably itself, and the latter has from its pilot hole that passes 1322.The following cylinder-shaped bearing 1324 that annular ring 1320 usefulness one are fixed on the bottom surface 1170 of housing 1158 is held in accurately to be axially aligned.Ring 1320 just can be combined in or comprise different drive units later, is included in the gear teeth 1326 of the periphery setting of ring.

In Figure 66, nozzle assembly has short post 1332, and the latter has central opening 1333 therein.Axle 1334 keeps axially aligning accurately by a cylinder-shaped bearing that is fixed on the bottom surface 1170 of housing 1158.Axle 1334 comprises the post 1338 that stretches in the opening 1333.Post 1338 comprises double-vane plate 1340, and they radially stretch in the groove 1342 that forms the opening 1333 of nozzle assembly 1164 from it.This is an important aspect of the present invention, and promptly motor 1330 usefulness are come out but through independent mouth 1344 liquid driven of coming out without nozzle, and, according to purposes, can not need the chamber fully.This independent mouth also can be combined in the housing of Figure 65, preferably post 1312 is clogged.No cell structure

The invention provides a kind of liquid discharge apparatus that sends liquid by basic jet graphics uniformly.The motion of equipment is swing, best and some rotation combination.Swing produces by produce member or the swing turbine swung with a body member supporting one in the liquid feed lines, and body member may comprise shelf, beam, housing and/or other structural member.With typical different based on the nozzle in hole, body does not need to comprise pressure or leakage liquid not, and may open wide in fact substantially.The water that flows through the swing turbine makes rotation of swing turbine and swing.The swing turbine just leaves the guiding of the jet graphics of nozzle later on, and the axis of winding apparatus is by the graphical distribution liquid of rotation.Leaving liquid stream deflector that the swing turbine distributes stops and is led downwards again.The gradient of swing turbine and the deflector loss of momentum that makes liquid stream of will hanking is minimum.According to the present invention, deflector can be provided with in any suitable manner, for example as the inalienable part of body or swing turbine or all as independent part setting.

The injection circle that is produced by the swing turbine more or less changes, and is directed to along the circular arc path so that drop or liquid flow overtimely, rather than is directed on a position continuously.This class spray distribution figure is softer than many fixing figures, and the unique design of swing turbine does not comprise complicated mechanical part or great throttling.For some purposes, it is desirable to, on deflector, cooperate, so that liquid flow is cleaved into the liquid stream of a plurality of dispersions with dispenser.

Another embodiment of the present invention provides a liquid discharge apparatus, and it produces the member or the swing turbine of swing with one, and the latter makes supporting produce the member of swing or the body or the housing of turbine also swung.More more specifically, the member that produces swing is placed to and the body of equipment or contacting of housing Cheng Song, thereby reduced the number that reaches the needed parts of this motion, and raising equipment is desired such as jet width that is used for family's shower or tap and figure.Liquid leaves the surface of swing turbine by the rotation figure and is distributed, not having throttling ground warp overshoot device then walks downwards, the outlet of arrival equipment, this outlet can be uncovered basically, maybe can comprise the non-restraining deflector or the path of any amount and configuration.As used herein, term " downward " or " downwards " refer to, there is one first jiao to leave the liquid that the swing turbine distributes and so be deflected with longitudinal center line, so that liquid changes over the second less angle with its direction with respect to the center line of liquid inlet with respect to the liquid inlet.

Though the swing turbine can be imagined as by any first jiao of distribution liquid less than 90 degree, turbine should preferably leave axis less than 45 degree to leave the angle distribution liquid of axis less than 60 degree, and is more better, leaves about axis 30 degree to 40 degree.The liquid that distributes from turbine should be admitted or stop to deflector, and this turbine has a surface, its angle make to liquid leave first jiao that turbine distributes similar.In addition, though deflector can be with many angles, even towards the angle of longitudinal center line rather than the angle of the leaving axis liquid that leads again, the gradient that deflector also should have smoothly, gradually change is so that the more intensive fluid discharge figure that provides otherwise than given turbine to be provided liquid again.Preferably, deflector with one be parallel to longitudinal center line+the angle liquid that leads again within the straight line about/-20 degree, even it is more better, deflector is with two or more angles liquid that leads again, for example, 12 paths 66 are arranged, and wherein four angle is made 0 degree, and other eight angle is made 10 degree.Will be appreciated that, because turbine swing, and some embodiment of deflector will depend on or be independent of swing turbine and swinging, so the turbine and the relative angle of deflector and the combination of angle often change, and further depend on structure by their connection, be the size of post and sleeve or the angle of oscillation that ring-swing plate or spatial constraints member etc. are allowed, at last, turbine and deflector surface are preferably recessed, so that the transition gradually that obtains leading, in guiding, not big loss of momentum when current are advanced than minimum of a value, and water does not have excessive splash or atomize.

The member of generation swing or swing turbine are placed to directly and engage or contact with the body of equipment.More more specifically, body member is by becoming spaced relationship supporting swing turbine vertically with the liquid inlet, and piping support does not require to have mechanical connection such as flexible joint or ball-cagelike structure, still the relation of the male-female of pine relation as most preferred post and sleeve.Term " relation of post and cover letter ", as used herein, comprise any amount of configuration, at this place, the post (male contact) cylindrical, conical surface that forms an outside is received in the sleeve (male contact) that forms an inner cylindrical, taper or frusta-conical surface, to allow to produce betwixt swing by loose ground.The bottom surface of post is preferably made round otherwise makes other shape, to reduce friction and the interlock between the member.Will be appreciated that the inalienable part that sleeve can be used as body or housing forms, post can be a part that produces the member of swing, perhaps conversely.Preferably post is become to have betwixt enough tolerances with sleeve design, can swing and aclusion with respect to body or housing so that produce the member of swing.In addition, most preferably adopt the relation of post and sleeve, they have taper or frusta-conical surface at least a portion of the post with first diameter, contact to be used for doing to roll with taper at least a portion sleeve or frusta-conical surface, that this sleeve has is bigger, by the diameter that becomes spaced relationship to be supported with the liquid inlet vertically.Taper or frusta-conical surface should have common top, so that make the surface do to roll completely contact.

The swing turbine can be with body, shelf or the housing of equipment by any configuration supporting, but the most handy a series of thin fin, is preferably the thin fin supporting that three or four radially extend from the wall of the body, shelf or the housing that are positioned at the exit passageway below.Adopt thin fin generally to be enough to supporting swing turbine, and the restraining of the bulk flow of convection cell needn't be set.Another kind of scheme is that the swing turbine can be used the independent arm supporting of extending along a side of equipment.

Equipment demonstrates such ability, can use low discharge work, and the current of a useful especially satisfaction in the immersion tap can be provided again simultaneously.Because swing is arranged, from equipment exhausting come out to lip-deep distribution of liquid and covering be extremely uniform, and can be feature with the rotating liquid distribution of rotating disc as defined in U.S. Patent Application Serial 09/115362, this patent be combined herein, with as a reference.Therefore, distribution pattern permission equipment has path less and that have the less throttling of bigger sectional area, and this sectional area is unlikely by lime, other mineral matter or particle restriction or obstruction.

Although the swing degree can with between post and the sleeve or the tolerance between oscillating deck and the spatial constraints member limit, equipment can randomly further comprise the active the swing limiting member.Swing limiting member initiatively such as orbit ring come work as the self-centering mechanism that is used to swing turbine.

Will be appreciated that.Equipment of the present invention and each part thereof can be with any known material manufacturings, preferably the material of those anti-chemical attack and thermal shocks from its liquid that flows through.At liquid is the place of water, and preferable material comprises plastics, more better such as injection moldable of one or more or the polymeric material of extruding, and is acetal resin, and metal or alloy, as stainless steel.For the person skilled in the art, other material that is suitable for using in the present invention should be clearly, and all thinks within the scope of the invention.

Figure 36 is the side sectional view of an embodiment of equipment 540 of the present invention.Equipment 540 has the housing 542 with a upper end and a lower end, and this upper end limits a ring-swing plate that extends internally or a ring portion 544, and lower support one has the sleeve 546 of the inner surface 548 that is roughly truncated cone shape, and this inner surface opens wide towards the upper end of housing.Equipment comprises a water inlet, and the latter limits an annular flange 552 that is used to admit the ring portion 544 of housing 542.Swing turbine 554 has a lower end or a post 556 that is positioned at sleeve 546.The inner surface 548 of sleeve 546 has than the bigger internal diameter of the external diameter of swing lower end of turbine or post 556 and does circular lower end along its most of length.

Swing turbine 554 has a upper surface 558, and the latter is substantially tapered and form the fin 560 of a plurality of generation angular momentums from its extension.According to the present invention, groove and fin use substantially interchangeably, to reach same purpose.But, the thin moulding fin of expection will transmit suitable vibrative power to turbine, rush down liquid down from the turbine surface with the single angle by the regulation of the conical surface between the fin simultaneously.On the contrary, on half surface area, have the surface of groove will be, and a semiliquid drop with another angle (supposition is the angle at the peak between the groove) with an angle (supposition is the angle of the trough valley) semiliquid that drops.

The upper surface of swing turbine 554 is preferably formed as an annular that faces down end 556 and overhangs.Lower end 556 is one to have and do the columniform post of being roughly of circular bottom surface 563.Cone-shaped upper surface 558 is preferably in top 562 and does circular.Can comprise optional shell body 564 for purpose attractive in appearance, but preferably not contact with swing housing 542.Housing 542 forms the band dispenser of an one or the deflector of path 566.Deflector surface 567 is a level and smooth arc preferably, it by uniform mobile graphic with the loss of momentum of minimum guide water downwards gradually.

After assembling, the post 556 of swing turbine 554 leans against in the sleeve 546.Swing turbine and sleeve can be with any suitable material manufacturings, but the most handy one or more injection moldable or the polymeric material manufacturing of extruding, most preferred is acetal resin as DELRIN.Will be appreciated that the swing turbine all is in to roll with sleeve and contacts, their material should provide certain friction on demand, to produce the consistent all the time swing or the motion of spiraling, but friction can not be too big, particularly at the far-end of post, in order to avoid momentum of wasting water or the interlock that produces turbine.Turbine and sleeve preferably contact with each other along frusta-conical surface, and its contact area is a controllable factor when friction big or small of determining therebetween.

When work, water enters through water inlet 550 and impacts on the top of swing turbine 554.The power on conical surface 558 and the fin 560 of acting on is together with the joint of post 556 in frusta-conical surface 548, the swing that produces swing turbine 554 when contacting with current or being impacted by it.The swing of swing turbine 554 reaches swing on the housing 542, and in the latter, the ring-swing plate 544 of housing is around annular flange 552 contacts and swing.Need not limit the scope of the invention, can think, when making swing turbine 554 wind center line clockwise direction swing from the current of water inlet 550, housing 542 counterclockwise rotates around center line.Water is directed to or is distributed on the deflector 567 of nozzle body 542 with fin 560.

In Figure 36, also illustrate, can adopt a volume control device such as needle-valve 568 to be controlled at the flow of the water on the turbine.This needle-valve identical with shown in Figure 21 of undelegated U.S. Patent Application Serial 09/150480 still, this patent is engaged herein, with as a reference.

Figure 37 is the side sectional view of another embodiment of the present invention, and wherein, the element similar with Figure 36 is marked with identical reference number.In this embodiment, equipment 551 has fixing housing 543, and the latter forms on the opposite of water inlet 550 and supports a sleeve 570, and sleeve has the inner surface 574 of a truncated cone shape, is used for loose ground and admits the sleeve 546 of being delimited by the deflector 571 of swing.Deflector 571 has a upper end 572, it be open wide and be not fixed on as shown in figure 36 on the water inlet 550.Swing turbine 554 rests in the sleeve 546 of deflector 571, and deflector 571 then rests in the case follower 570.When hydraulic shock swing turbine, turbine 554 and deflector 571 are all swung.

Figure 38 is the cutaway view of another embodiment of the present invention.Equipment 561 has a fixing housing 543, and it has a water inlet 550 in the top, and a plurality of thin fins that radially extend are arranged in its lower end, and latter's extension between the inwall of housing 543 and sleeve 570 is to be bearing in bearing sleeve 570 in the nozzle housing 542.Swing turbine 554 has cone-shaped upper surface 558, and it has a plurality of fins 584 from turbine 554 outward extending generation angular momentums.The opposite end of fin 584 all is connected on the deflector 586, and to form wheel one spoke type structure, the latter marks path 566 (simultaneously referring to Figure 39) betwixt.Flow passage 566 forms between fin 584 and deflector 586, at this place, and the current that act as dispersion process path 566 of fin 584.Deflector 586 is illustrating the optional extension 576 of Shi Youyi, and it extends upward from fin 584, leads so that comprise the current and the downward process path 566 that get off from turbine again.

Figure 39 is the perspective view of turbine 554 shown in Figure 38, and invisible part is shown in broken lines, and for clarity, the extension 576 of deflector 586 is removed.Each fin 584 radially stretches out around post 566.Each preferably has the side 590 of 11 angle, and it is given turbine 554 and rotatablely moves with one when contacting with current.Side at angle preferably forms the angle of one 5～15 degree with vertical side, more better is about 7 degree.Determine current that the turbine response contacts with fin change how soon the time, the tilting value of angle is important.Water slug is walked downwards on the top of fin and along side 590 at angle, thereby promote turbine 554 (from illustrated configuration from top along clockwise direction of rotation, though another kind of configuration also may produce anticlockwise rotation), the latter produces the counterclockwise swing of turbine or spirals.The mechanics of this motion at length still is being described in the undelegated U.S. Patent Application Serial 09/115362, and this patent gives combination herein, with as a reference.Fin and deflector cooperating, the latter has an inner surface that opens wide downwards, to guide water by one or more desirable angles.

When the supply of water was connected, water entered housing 543 and impacts the top of turbine 558, and turbine is tumbled to a side and swing in sleeve 570.Water is deflected, and leaves turbine 558, and through exit passageway 566, thereby impact fin and make the turbine rotation.Housing 543 the most handy 3 or 4 thin fin 571 bearing sleeves 570 that radially extend, this fin extends towards sleeve 570 from the inwall of housing 564.Turbine is swung and immediately with the discharge water that distributes very uniformly.

Figure 40 is the cutaway view to similar equipment 561 shown in Figure 4.Deflector 586 can have a swing limiting element or an orbit element 580, and the degree that turbine is tumbled is swung in its restriction that act as in sleeve 570.Swing limiting element 580 is preferably formed as cone-shaped upper surface 558 frusta-conical surface 582 of turning around with respect to swing turbine 554, so that when surperficial 582 the time from 550 water slugs of flowing out that enter the mouth, turbine is by back 550 center line pushes away towards the liquid inlet.

Liquid discharge apparatus also can be provided with water management element or bypass 592, and the water that the latter allows to add flows through equipment.Water management element 592 can be made up of compression spring one valve seat 584, and this valve seat inner surface towards housing 543 when valve is in the closed position seals.

As shown in figure 41, if require that bigger current are arranged, the hydraulic pressure that is conducted to equipment can strengthen by opening a valve (not shown), does until spring passive, and seat is thrown off with the inner surface of housing 543, thereby allows more water to flow through housing 543.In the configuration herein, additional current are directed in the outside of swing turbine 554 towards the wall of housing 543 usually, therefore can not influence the swing degree that turbine 554 and nozzle housing 542 are experienced.

Figure 42 is and the side sectional view of a similar equipment shown in Figure 36, and just body or housing 543 are not swung, and save arbitrarily, ornamental shell 564.The fin 560 that swing turbine 554 has a conical surface 558 and extends from upper surface 558, this upper surface are outwards towards inwall 561 guiding current.

A plurality of thin fin 594 bearing sleeves 570 that extend to sleeve 570 from the inner surface of housing 543 of housing 543 usefulness.The deflector 567 that forms on the inwall of housing 543 can randomly comprise ridge or dispenser 569, and the latter will split into the current of dispersion from the current of turbine.Different with other embodiments of the invention of former discussion, equipment 573 does not produce the swing jet graphics, but aperture that need not may be blocked still provides a kind of many water distribution figures that are divided into thin drop that comprise.Compare with popular shower nozzle, another advantage of the present invention is for reduce producing effective water distribution figure such as being used for shower, washing one's hands and the number of the needed parts of figure of analogue.The liquid inlet that should be pointed out that present embodiment and any embodiment previously discussed can be equipped with flow control valve, so that suitable current to be provided.

Figure 43～45th, the vertical view of the various taper end faces 558 of turbine 554 shown in Figure 36.The end face 558 of shown swing turbine 554 has the fin 560 that forms by non-radial configuration.Should be understood that, the liquid stream of impact on the swing turbine will push away the swing turbine to the side, arrive a tilted position,, and have only a side of swing turbine in time to align with liquid stream in arbitrary position so that the mid point of swing turbine is substantially in the outside from the liquid stream of inlet.Each fin 560 of forming at the upper surface of swing turbine 554 all right and wrong radially and makes swing turbine 554 550 make circular motion around the liquid inlet when fin 560 flows at liquid.The relation of pine pine between non-radial fins 560, conical surface and post and the sleeve guarantees, when liquid is having under the situation of pressure (even low pressure) when flow in the top of swing turbine 554, the swing turbine will depart from the center and begin swing.More more specifically, impact liquid on the conical surface 558 of turbine and produce the power of tumbling, the liquid that flows to fin 560 then produces revolving force.Therefore, the liquid stream that passes inlet makes the swing of swing turbine.

In case swing beginning, continuous current keep the swing turbine to be in weave mode.In addition, flowing of liquid also produces one toward the power that presses down, and it pushes away downwards on turbine, tries hard to make turbine not from the cooperative relationship displacement of itself and sleeve.Therefore, preferably make the angle of conical surface 558 enough big, even so that when turbine is tumbled fully, also can produce at least one little power of tumbling, but it can not be greatly to up being drawn turbine, and disengaging contacts with sleeve.Will be appreciated that each of the embodiment of Figure 36 to 46 all is equivalent, as long as the swing turbine comprises a sleeve (rather than post), and nozzle boss comprises that one is used for and swings the post (rather than sleeve) that the turbine sleeve engages.

For any known swing turbine, rate of oscillation or speed can strengthen (or reducing) through the flow of the liquid of shower nozzle by strengthening (or reducing).But, to given fluid flow, the groove that also can be by changing the swing turbine or the angle of fin or the gradient or turbine is designed to faster or slower swing speed by the relative size that changes post and sleeve or other similar oscillating structural member and swing limiting member.

Referring to Figure 43, the swing turbine can promptly design fin 560 and be designed to a usually slower swing speed with the little angle beta that leaves radially by the gradient and the degree of depth that reduces fin.Equally, the swing turbine can be by strengthening the gradient of fin, promptly leaves angle δ design fin 560 radially and be designed to a swing speed faster with bigger as shown in figure 44.In addition, the quantity of fin or the gradient and size also can be revised, with a rate of oscillation customized as shown in figure 45, in Figure 45, fin 560 separates farly, so that quite most water does not impact one in the thin wing sheet 600 through turbine, thereby provides less angular momentum to turbine.

Figure 46 is the bottom view of the shower nozzle of Figure 37 to 41, and it illustrates the exit passageway of housing.Though exit passageway can be with any way setting known in the present technique,, preferred exit passageway group 604 is to be limited by a plurality of ribs on the inner surface 610 that is connected to nozzle housing 542 or dispenser 606.Four fins 608 are contained on the housing 543 and also radially extend internally, with bearing sleeve 570.Preferably sub-fraction exit passageway 604 is guided on the axis of nozzle housing 542, so that the people's who for example has a shower at object from shower nozzle with short distance outside provides jet graphics and covering more stably with less angle.The less exit passageway of angle preferably with the distance that separates around nozzle periphery or radially inwardly forming (not shown) towards the place of the central axis of nozzle housing.

Figure 47 is the side sectional view to similar equipment 581 shown in Figure 36.This embodiment comprises the relation of post and sleeve between body 542 and turbine 554, but this relation is an inverse relation shown in Figure 36, promptly swings turbine 554 and forms one by the sleeve 612 of post 614 loose grounds admittance, and at this place, post 614 is integral with nozzle housing 542.Swing turbine 554 and contact from the water that exports 550 and tumble, and begin swing along a direction.Successively, sleeve 612 contacts with post 614, and the latter makes housing 542 tumble and swing.

Figure 48 and 49 is the cutaway views to similar equipment 620 shown in Figure 36, just swings turbine 622 and limits one and pass the top of turbine 558 and pass post 556, preferably along hole 624 that the medial axis of turbine is extended.The lower end of sleeve 546 limits an opening 626 therein.One valve element 626 is arranged on the lower end of sleeve 546, and it act as the flow that changes the water that leaves shower head assembly 620.The valve element can be taked many kinds of forms, comprises plug valve, needle-valve, butterfly valve, gate valve and analog thereof, but then illustrates as manual gate valve or sliding members 628 herein.When sliding members 628 is in when opening situation, water flows through the hole in the swing turbine 622 624 and the opening from sleeve 546 626 comes out.This mobile graphic provides a pair of cleaning shaver, toothbrush or other object useful intensive current.As shown in figure 49, when sliding members is in when closing situation, water is forced to flow through turbine and comes out through exit passageway 566.Another kind of scheme is, the inner surface 548 of the lower end of close sleeve 546 can inwardly become a gradient, so that be in when opening situation when sliding members 628, turbine lower falls, fixed by housing, just look like to be fixed, and/or fixed with the housing of the following side engagement of swinging the turbine head securely by the sleeve of grasping post.Should be pointed out that any embodiment shown here all applicable to adopting similarly swing turbine, the latter has hole and the valve element that passes it, so that narrow current that come out from equipment to be provided.

Figure 50 is the side sectional view of shower head assembly 630, and it is to shown in Figure 36 similar, and just shell body 564 has an arm 632, and bold ground of latter bearing sleeve 546 so that swing turbine 554 and housing 546 is swung independently, does not contact each other.When not contacting, the power that acts on the turbine 554 is not directly reached on the housing 542, but water is re-oriented by the inner surface towards housing radially through turbine 554 outsides and what, so that housing is tumbled.When turbine was swung, the water that gets off from turbine 554 made housing 542 swings.

Figure 51 is the side sectional view of equipment 640, and it is to shown in Figure 50 similar, and just sleeve 546 a usefulness cage type or wall shape element 642 550 support from the liquid inlet.Swing turbine 622 has one from its hole of passing 624 to shown in Figure 14 similar.Cage 642 bearing sleeves 546 are not so that when swing turbine 622 moved with housing 642, cage and sleeve moved.Cage 642 is made up of the arm 646 that is fixed on liquid inlet 550 and the sleeve 546.Arm 646 has thin cross section, so that they do not interfere with the current that leave assembly 640.The swing limit collar 648 that is used to limit the swing of turbine 622 extend out to just certain position above swing turbine 623 from water inlet 550, so that the taper end face of swing turbine can contact with the inner surface of ring 648.The swing degree of housing 542 similarly is subjected to the restriction of ring-swing plate 544 and a ring portion or spatial constraints device 552, comprise swing confinement plate 650, the latter contacts with the top of housing 542, with restriction swing degree, thereby allows as shown in figure 48 intensive current.Swing confinement plate 650 can longitudinally be conditioned, to allow housing 542 vicissitudinous swing degree.

Figure 52 is the side sectional view of an equipment 652, and it is to shown in Figure 50 similar.This design is for example particularly useful in the shower in some residential block or suburb in the purposes with low hydraulic pressure.The angle of face of swing turbine 554 and the narrow configuration of housing 542 only provide water must the place of entering of housing 542 to enter the mouth 550 and the outlet of housing 542 between a small amount of change of angle in the path of walking.This design allows current to be subjected to the minimum loss of momentum, thereby is the minimum reduction of the speed of water.

Assembly with Figure 50 is the same, and shell body 564 bold ground bearing sleeves 546 though it is made like this of fin 633, like this, just can not contact with each other when swing turbine 554 and housing 542 swings.When contactless, the power that acts on the turbine 554 is not directly reached on the housing 542, but water impacts with the face of angle (α) to turbine 554, and be re-oriented towards housing 542 with little incidence angle (β), so that housing is tumbled, but water just slightly is re-oriented, so the speed loss of water is as far as possible little.

Will be appreciated that angle [alpha] is the function of the appearance of the common axis line with water inlet 550 that allows turbine spindle to leave it angle of tumbling and turbine for the angle of turbine spindle simultaneously.Equally, angle beta is the angle from the sidewall of the angle of the current that are re-oriented on the face of turbine, housing 542, and the function that allows the angle that housing 542 tumbles with respect to the medial axis of water inlet 550.Low-pressure structure

The invention provides the nozzle component of the nozzle of a band motion, this nozzle is by speed or the loss of momentum and the in check drop size transmission liquid of desired jet graphics with minimum.The motion of nozzle is swing, best and certain combination that rotatablely moves.Swing is by producing housing being arranged or do not have to be provided with in the liquid feed lines of housing a member or a swing turbine that produces swing.The water that flows through the swing turbine makes the swing of swing turbine.After, the swing turbine just leaves the guiding of the jet graphics of nozzle.

How many changes promptly of jet graphics by the swing turbine produces are directed to along the circular arc path so that drop or liquid flow overtimely, rather than are directed on a position continuously.This class spray distribution figure is softer than many fixing figures, and the unique design of swing turbine does not comprise complicated mechanical part or great throttling.This swing, rotation one liquid distribution of spiraling be described in please series number 09/11536 in common pendent United States Patent (USP), and this patent gives combination herein, with as a reference.

One aspect of the invention is provides one with an equipment that produces the member of swing, and a plurality of exit passageways of this member and a plurality of guiding liquids are integral.Adopt this structure, fluid flow can reduce, but distribution liquid stream on the area of width equably again simultaneously, and do not rely on little exit passageway or aperture.The swing turbine can have supporting or the supporting of the housing of sleeve with one, and sleeve is installed on a plurality of thin fins that extend from the outer wall of housing.Fin is positioned at the below of the exit passageway of turbine, and the minimum interference with total liquid flow is provided.Such housing is desirable for providing satisfied current with little discharge, and this is particularly useful in the immersion tap.As so used, term " housing ", " body " and " shelf " are to use synchronously, broadly to refer to a fixed component or scaffold, do not plan to be restricted to the wall or the chamber of encirclement.

Produce the member of swing or swing turbine around a current shifting that contacts with the swing turbine.More more specifically, the member that produces swing is placed to the housing of equipment does contacting of pine, thereby has reduced the number of part, and has improved the ability that equipment produces desired jet width and figure, for example for the shower head or the tap of family.In addition, water is deflected and does not run to with having throttling substantially exit passageway along the swing turbine, and the latter can be by any amount and any configuration setting.

The member that produces swing preferably is placed to housing and directly engages or contact.More more specifically, housing has an end away from water inlet.Preferably, the far-end of housing and the member that produces swing are easy to slide or swing into the place of suitable unrestricted relation.Particularly preferred layout is that the post (sun) that forms cylindrical, taper or frusta-conical surface is received within taper or the truncated cone shape sleeve (the moon), at this place, the bottom surface of post is preferably made circle, or otherwise shape is made the friction and the interlock that make between the member is minimum.Will be appreciated that the inalienable part that sleeve can be used as housing forms, post can be a part that produces the turbine of swing.Preferably post is become to have betwixt enough tolerances with sleeve design, can swing and aclusion with respect to nozzle body so that produce the member of swing.In addition, most preferably, adopt the member of the generation swing with cone-shaped upper surface that first diameter is arranged, wherein, cone-shaped upper surface forms around a post with second little diameter, and this second diameter is received within the taper or truncated cone shape sleeve of nozzle body.

Preferred swing limiting member is the orbit ring that forms in the upper end of housing.The upper surface of swing turbine or top are done rolling with orbit ring and are contacted when being driven by the current from the inlet in the top of housing.Housing can be for example by the threaded connection relation between the top and the bottom of housing forward, be conditioned along length (as Figure 67 in vertical direction), thereby correspondingly change the deflection angle that is used to swing turbine.Make the more approaching swing turbine of orbit ring, will reduce the width of jet graphics, and leave swing turbine moving track ring, will strengthen the width of resulting jet graphics.

Will be appreciated that nozzle component of the present invention and each part thereof can be with any known material manufacturings, preferably the chemical attack of those anti-liquid through wherein and the material of thermal shock.At liquid is the place of water, and preferable material comprises plastics as the polytetrafluoroethylene (PTFE) and the metal or alloy as the stainless steel.Other material that is suitable for using in the present invention all is clearly for those skilled in the art that, and all thinks within the scope of the present invention.

Figure 67 is the cutaway view of an embodiment of equipment 1410 of the present invention.Equipment 1410 has the housing 1412 with a upper end 1414 and a lower end, and this upper end limits a track that extends internally 1416, and the lower end limits one and has the sleeve 1418 that is roughly truncated cone shape inner surface 1420, and this inner surface opens wide towards the upper end 1414 of housing 1412.Equipment comprises a water inlet 1422 in the upper end of housing, and it preferably aligns with the medial axis of housing 1412.Swing turbine 1424 has one to be arranged in the sleeve 1418 or the lower end or the post 1426 that extend therein.The inner surface 1420 of sleeve 1418 has on its most of length than the lower end of swing turbine 1424 or the bigger internal diameter of external diameter of post 1426.Track 1416 be substantially annular and play a part the swing limiting member, to limit the swing swing degree that turbine was experienced and to produce rotation.Will be appreciated that, swing turbine 1412 is done to roll with track 1416 and is contacted, and their material should provide some friction at least on request, to produce the consistent all the time swing or the motion of spiraling, but it is not too big to rub, so that the interlock of the momentum of consume water or generation turbine.The contact area of turbine and track is a controllable factor when friction big or small of determining therebetween.

Swing turbine 1424 has upper surface 1428, a mid portion 1430 and a bottom or a post 1426 that is roughly taper, and mid portion forms a plurality of radially from its blade that stretches out 1432.The mid portion of swing turbine 1424 preferably has one to connect the wall 1434 of each blade 1432, so that form exit passageway 1436 between adjacent vanes 1432.The lower end of swing turbine is one to be roughly columniform post 1426, and it has does circular bottom surface.Cone-shaped upper surface 1428 preferably points to summit 1435.The far-end of housing 1412 is uncovered substantially, and has sleeve 1418 is fixed on thin wing sheet 1433 on the housing.Exit passageway 1436 can vicissitudinous dimension the profile of the inner surface 1438 of angle or wall 1434 for example so that by uniform mobile graphic guiding water.

After assembling, the post 1426 of swing turbine 1424 rests in the sleeve 1418.The sleeve of swing turbine can be with any suitable material manufacturing, still the most handy one or more injection moldable or the polymeric material manufacturing of extruding, the most preferably acetal resin as DELRIN.Preferably very little friction is arranged at post 1426 and 1418 in sleeve.

When work, current enter and impact the end face 1428 of swing turbine 1424 through water inlet 1422.Flow action produces swing turbine 1424 in the power on the conical surface 1428 when the swing turbine contacts with current swing.The swing of swing turbine 1424 also (suppose the turbine blade gradient shown in Figure 2, looks from the inlet of water) that the center line of the liquid stream that the inlet 1422 around water comes out contacts with the inner surface do rolling of track 1416 in the counterclockwise direction.Water is past dirty along the top of swing turbine, and is deflected wall 1434 guiding, enters in the exit passageway 1436.Wall 1434 preferably upwards extends above blade 1432, and substantially along the angle that restrains towards the center line of equipment.

The relative angle of swing turbine surface 1428 and wall 1438 is so design preferably, so that liquid keeps big as far as possible speed and momentum.Though the swing turbine can be envisioned for the first jiao of distribution liquid that leaves axis less than 90 degree with one, but turbine should leave axis less than 45 degree with one, preferably leave axis less than 30 the degree, more better leave axis 20 the degree about and 30 the degree about between angular distribution liquid.Deflector wall 1434 should admit or intercept from having the liquid that surface 1438 turbine distributes, and this surface has first jiao of leaving that axis and liquid leaves that turbine distributes identical or than its little angle.Though surface 1428 and 1438 all illustrates as straight, these surfaces also can be to make crooked or profiling, and for example turbine surface 1428 is recessed outward, and deflector surface 1438 concaves.In addition, that rib can be made in surface 1428 or fin is arranged, so that help liquid inlet passage 1434 better.

Though deflector can be with many angles liquid that leads again, even angle is towards longitudinal center line, rather than angle is left axis, but deflector should have a level and smooth surface 1438, and the latter is directed to liquid the more intensive liquid distribution figure that provides by other method than given turbine again with enough gradient.Preferably, deflector with one be parallel to longitudinal center line+the angle liquid that leads again in the straight line about/-20 degree, even it is more better, deflector is with two or more angles liquid that leads again, 12 paths 1466 are for example arranged, wherein four angle is made 0 degree, and other eight angle is made 10 degree.

Angle of oscillation, thereby be jet width, the position on top that can be by changing housing is regulated.Top engages with lower part of frame with screw thread, so that the bottom can be regulated along level up or down with respect to the center line of swing turbine.Therefore, if the user needs the distribution pattern of a broad, then lower part of frame can be regulated downwards, so that a bigger space (the bigger angle with respect to longitudinal center line) that is used for the turbine rotation to be provided.Equally, for narrower distribution pattern, the bottom can be by to adjusted, with restriction swing degree.

Figure 68 is the partial sectional view of the turbine 1424 shown in Figure 67.Blade is done at an angle, and is guided downward and come out from turbine with the current that use arrow to represent, makes the turbine swing, is preferably made needed as far as possible little deflection, with liquid velocity or the momentum of avoiding damage.Make from the place that contacts with the turbine top angular deflection to the flow path of the liquid of the far-end of exit passageway for minimum, can utilize the low pressure current most effectively, for example those have the current of the pressure of 2～3 pound per square inches (psi).If hydraulic pressure is higher than required, then water inlet can be equipped with flow control element, to regulate the water yield of inflow equipment.Will be appreciated that the person skilled in the art can revise the angle on the blade 1432, to adapt to special purposes.

Figure 69 is the perspective view of the turbine 1424 shown in Figure 67, and invisible part is shown in broken lines.Each blade 1432 radially extends around post 1426.Best blade 1432 has does angled side 1440, and the latter makes turbine 1424 make angular motion when contacting with current.Do angled side 1440 and be preferably formed as angles that become 5～15 degree with vertical side, more better is about 7 degree.The gradient of angle influences turbine will change how soon in response during with current that blade contacts.Water slug is down walked on the top of blade and along doing angled side 1448, thereby clockwise direction pushes away turbine 1424.Blade is cooperated with wall 1434, and the latter has one to open wide downwards, with the inner surface that water is guided by one or more desirable angles.

When water enters housing 1412 and impacts the top of turbine 1424, turbine will be tumbled to a side and swing counterclockwise in the scope that is perhaps also had sleeve 1418 to set by orbit ring 1416.Water is departed from and the process exit passageway from turbine surface 1428.Housing 1412 the most handy 3 or 4 thin fin 1413 bearing sleeves 1418 that radially extend, fin extends towards sleeve 1418 from the inwall of housing 1412.

In a preferred embodiment, the top of swing turbine is level and smooth conical surface 1428, and it has a center line with respect to the swing turbine to be about the gradient of 22 degree.The inwall of deflector wall forms an angle that becomes with the center line of swing turbine about 17 degree, so that liquid changes with the direction of minimum and minimum speed or the loss of momentum is crossed and walk through the swing turbine.This design is low at hydraulic pressure, so as to make flow or speed further reduce become minimum district work get good especially.

Figure 70 is the cutaway view of second embodiment of shower nozzle.A raceway surface that is provided by annular ring 1442 is provided shower nozzle 1440, and this ring is fixed in the cannelure 1444 that forms in the surface 1416 of housing 1412.Annular ring 1422 is preferably with having material such as the rubber or the soft polymeric material manufacturing of smooth non skid matting, contacts with the surface 1428 of turbine 1424 being used for.Anti-skidding annular ring 1442 helps to guarantee that turbine rotates when it is swung, rather than slides and do not have rotation around track.

Figure 70 also shows the two-part construction of the uniqueness of swing turbine 1424.Whole molded swing turbine/post arranged with it, not as good as turbine is configured to a blade assembly, with column assembly 1448 cartridge clips or be fixed on other method on the bottom of blade assembly 1446.Go back to see Figure 67, blade assembly can also be fixed on the column assembly on the top of blade assembly.Under the situation of two-piece type swing turbine, each part can be fixed together with traditional measure, and they include, but are not limited to glue, screw thread, friction, ribbed, welding etc.

At last, Figure 70 comprises flow-control ring 1450, and the latter is arranged in the inlet 1422 of shower nozzle 144, with the flow of control through shower nozzle.Typical flow-control ring is by the principle work of compression rubber.This ring can obtain from the Vernay Labs of the Yellow Springs of Ohio by trade name Vernay.

Figure 71 A and 71B are the cutaway views of the shower nozzle 1460 of carrying liqs inlet 1422, and inlet is respectively at standard-sized sheet or there is the position of throttling that the variable aperture of optional sectional area is arranged.Control the sectional area of this aperture, just allow the user to change the speed of water, impact and drop size with control.

Figure 71 A illustrates the inlet 1422 of the throat region 1466 of band taper or stenosis, and throat region is communicated with valve with first end 1464 or insertion member 1462, and first end can stretch in the inlet 1422, to reduce the net sectional area of inlet 1422.Insert member 1462 the most handy knobs or handle 1468 between the fully open position shown in Figure 72 A (referring to inlet) and the throttle position shown in Figure 72 B (refer to inlet reach fully by throttling) or any position action therebetween by member 1462 designs not by member 1462 throttlings.Knob or handle 1468 illustrate by being bonded on the eccentric pin 1467, this pin is communicated with the pilot hole 1469 that passes insertion member 1462, so that when pressing first direction turning knob 1648, pin 1467 (towards inlet 1422) is descended, and first end 1464 of member 1462 pushed inlet 1422, and by second direction turning knob 1648 time, pin 1467 (leaving inlet 1422) is risen, and first end 1464 of member 1462 is pulled out inlet 1422.Insert member 1462 the most handy yielding polymer or elastomeric material manufacturings, first end 1464 then preferably includes some grooves 1465, so that form a plurality of bendings when contacting with the zone 1466 of stenosis, so that easily stretch into the finger-type thing 1463 of inlet 1422.Another kind of scheme is, member or valve 1462 are valves of another kind of type known in the present technique, and especially those can provide the valve through the fluid flow stably of inlet 1422.

Figure 71 B is identical with Figure 71 A's, just inserts member 1462 by action (closing), with the net sectional area of restraining inlet 1422 valve portion.When fluid pressure during greater than 15psi, the restraining of inlet 1422 reduces the pressure reduction that strides across volume control device 1470, strengthens through the liquid velocity of inlet 1422, causes the liquid of the equipment that leaves that higher speed is arranged.Less pressure reduction makes volume control device 1470 rise to rib 1476 places, opens the passage that passes it.When insertion member 1462 was contracted (valve is opened), liquid velocity descended, and the pressure in the volume control device strengthens, closing passage.Like this, can keep flow constant, allow again simultaneously and change ground control and impact, no matter the pressure of fluid supply how.

Figure 72 A and 72B are in the cutaway view of opening with the fluid flow control device 1470 of closed position (simultaneously referring to Figure 71 A).Flow-control is according to such principle, and promptly being compressed in its pressure limit of working of spring is restricted.Typically be used to provide the water of 2.5 gallons of per minutes (GPM) the flow-control ring (as shown in Figure 70 like that) when pressure of supply water surpasses the 15psi left and right sides, work finely, but drop to 15psi when following when pressure, flow reduces rapidly.Therefore, the invention provides a bypass, being lower than at the liquid supply pressure about the 15psi that uses for the resident, but be lower than anyly as the time, strengthen total flow through liquid inlet 1422 to the given desired minimum pressure of purposes.

Fluid flow control device 1470 is float or unfixed members that the periphery of the amount of a streaming control loop 1450 formed and had a flange 1472, and flange has a plurality of shallow ribs 1476 that are molded as in the bottom surface of flange.Rib 1476 preferably rests in the rib that radially extends on the round section joint ring 1474, this circle is fixed on ledge or the groove 1478, when low supply pressure, between rib 1476, provide fluid passage, so that liquid is through flow-control ring 1450 and through control loop 1450 liquid make-up flows.When the liquid supply pressure strengthened, unsteady control device 1470 was down pushed away, and rib is sunk to for 1476 times in the O shape circle 1474 that deformable polymer or rubber does.When (or some other desired design pressure), rib 1476 is embedded in the O shape circle fully about 15psi, flows thereby cut off bypass fully.When liquid supply pressure (actual is pressure reduction) strengthened, the unique path that is used for liquid was through control loop.This system or suitable system be a big pressure limit that surpasses typical flow-control ring, particularly is of value to guaranteeing best performance when the low pressure of particularly suitable of the present invention.Another kind of scheme is to will be appreciated that O shape circle also can be fixed on the bottom surface of flange, to be communicated with the rib that forms on ledge 1478.

Figure 73 one has the cutaway view of supporting 1482 shower nozzle 1480, and this supporting is combined in the upper junction of turbine 1424 on the post 1426.Supporting 1482 can form by any known form, but preferably forms by the simple pin 1484 that stretches out from post 1426, and this post is received within the cylindrical sleeve 1486, rotates around pin 1484 to allow turbine.In this arranged, the top with turbine 1424 of sleeve 1486 can be with a speed rotation, post 1426 then the while with another speed rotation or do not change fully, thereby restriction or prevent any interlock of turbine.In addition, in order to make the outer surface of deflector 1434, or, make the rolled portion of the special use of turbine divide beginning to roll along track 1442 by a kind of scheme, the power that acts on the current on the turbine just must overcome the friction in the supporting, rather than overcomes the friction that may exist between post 1426 and sleeve 1420.

Have been found that equipment of the present invention produces desirable spray by producing big drop.The large scale of these drops is mainly caused by two factors.At first, liquid consequently has a large amount of liquid to can be used for making drop only in a side of once down passing through turbine.Secondly, the flow ring allows to adopt the large outlet path that throttling is not set substantially.

In addition, see that turbine of the present invention can be used for water is added air to a degree more or less.A spot of air that adds can take place, because water only passes a part of path 1432, as once taking place any in a side of turbine.If turbine thinks then that with very high speed swing water bunchy ground promptly flows through path with slug flow, and has the air that is full of between each bundle, is useful.When Shuitu was so passed through path, it promoted or drives the air of following it.

Return over again and see Figure 73, the air capacity of bringing into can by be provided with one be used for water flow through turbine or when the path path to current supply air strengthen.The special design or the method that are used to increase the air brought into be, an annular breach or groove 1488 are set, and the latter partly or entirely extends around turbine surface 1428.When water flow through breach, the air in the breach was held or is sucked in the water together.In fact, if breach is made around turbine air even can be sucked in the breach by the effect of water then.But, several parts of discontinuous breach or annular breach will be filled with air when it departs from current.When breach turned to current, air wherein can be inhaled in the water, to press from both sides with air.Can be used in combination according to one or more breach of the present invention or groove, perhaps be placed to not only on the top of turbine, and in the bottom of saturating sheet, blade, deflector or their combination.
