Description

Spray head

The present invention relates to a kind of spray head, said spray head has a shell and a surface, comes out from shell at this surface jet.There are many outlet openings the surface.Various forms of this type spray heads are long-term known and have many working methods inherently.

Problem involved in the present invention is to make a kind of spray head of the above-mentioned type, and this spray head has working method unknown in the prior art level and especially has useful purposes.

This problem solves through the spray head with following characteristics.A kind of spray head of the present invention has: shell, disk; Jet comes out from this disk; Above-mentioned disk has the aperture that many jets therefrom come out, and is used for making water to get into the water inlet of shell, an aerator; Said aerator is used for to the water inflation of flowing through spray head; In shell, has a mechanism that is used to form some water jets, guider, the radially water jet of deflection inflation and the aperture that is used for water jet is directed to whole jet disk in the smooth distributor chamber that is used for distributing therein.

Spray head comprises a shell, and the end of shell is sealed by its disk that comes out with a jet.This disk comprises many jets by its aperture that comes out, and said aperture can be shaped through some device is special.Especially, spray head comprises a big and flat shell.Air inlet can for example be constructed like this, so as it through jet by its disk that comes out, for example directly by the center of its preferably plane disc that comes out air is introduced in the shell at jet.

For the suitable in the enclosure distribution of water that obtains inflating; And the jet that therefore obtains inflating is in the specially suitable distribution of housing exterior; According to the present invention, in relevant detailed description of the present invention, spray head comprises and is used for certain mechanism in the enclosure portion forms some discontinuous jets.Therefore these discontinuous water jets form in the enclosure rather than form from the shell back of coming out at them, this with guaranteeing some operation relevant with water jet and they still in the enclosure.

In detailed description of the present invention; Aerator is constructed like this; So that it at the upper reaches from being used to form mechanism's feedwater inflation of jet, in this case, the mechanism that is used to form jet will be used for forming from a kind of jet of inflation the jet of discontinuous inflation; The jet of said discontinuous inflation can be distributed in the shell of spray head on the surface then, and above-mentioned surface has a diameter for for example greater than about 10-20 of water inlet diameter times.

Yet; The mechanism and/or the inflator that are used to form jet also possibly be, and be preferred for this invention, and they are constructed like this; So that in the past established discontinuous jet will jointly and/or individually be inflated, this can save the inflation that must when forming water jet, supply their back.

In relevant of the present invention describing in further detail; Spray head can have guider, so that in whole jet dish scope, preferably with a kind of uniform mode; Perhaps, the water jet of inflating is directed on the outlet opening if desired with a kind of mode heterogeneous.

The various diverse locations place that guider can be installed on the spray head or spray head is interior for example is installed in the distributor chamber, and above-mentioned guider just is shaped at the upper reaches of jet disk.Yet guider also can be installed in the local place that perhaps is installed in the jet that forms inflation to the jet inflation that forms.

For example; Have in the detailed description relevant with it; Guider and/or aerator are constructed like this, so that they produce turbulent flow in the jet of inflation, if produce turbulent flow; Then it will be comprising there being suitable being used to prolong the mechanism of the dwell time of jet in the shell of spray head, so as with its obtain with the spray head shell in the device that exists longer and/or contact more closely.

In relevant detailed description of the present invention, aerator can be constructed like this, so that it produces one air-flow, said air-flow and current meet at right angles and are incident on the current, and as stated, air-flow can be incident on the established discontinuous current in front here.

Yet aerator also can be, and the present invention includes the situation of aerator just, structure like this, so that it produces discontinuous air-spray or air-flow, per share then air-spray or air-flow separately are incident on the current.

Especially, it can guarantee that per share air-spray is all consistent with its incident current on it.Whole or only a part of segmentation of air-flow and current can import in the shell, and this can make discontinuous current be inflated in various degree, perhaps at the diverse location place they inflated.

In order to produce discontinuous water jet, the mechanism that is used to form jet can for example have the disk of a perforation, the installation that meets at right angles of the disk of said perforation and current.Each perforation will produce one water jet then.As stated, these water jets can be that all or only a part is isolated each other, so that various discontinuous narrow current will form in a shared water volume commonly used.

Aerator can have a center collar or hub, and surrounding air is passed the inside of the inside entering shell of above-mentioned hub.The substrate of hub can for example have a smooth surface, and said smooth surface and relevant mating surface form a flat doughnut together, and above-mentioned doughnut makes air-flow face toward water.Yet the substrate of hub can be and the present invention includes hub substrate situation just, also construct like this, so that it has for example groove of radial gas guider, and the segmentation of above-mentioned groove guiding air-flow.

The radial air guider for example two ends of groove or passage is aligned on the aperture in the apertured disk.The sort of aligning can for example be like this, so that the center line of groove is aligned on the center of circle of aperture.Yet also feasible is provides a kind of tangential to aim at like this so that the center line of groove be depart from from aperture with respect to apertured disk the center to above-mentioned tangent scope in.

Air-deflector can be accurately radially or a little to tilt.

It is on the plane vertical with its longitudinal axis, to flow basically that hub is held air within it, and above-mentioned hub also can be included in the guider of the jet that is used to inflate on its side surface, and above-mentioned hub is a cylindrical shape.These guiders can be to be aligned in perforation like the groove on the aperture of disk.These guiders are used for jet with inflation and remain in the shell of spray head discontinuously, that is to say, are used for postponing or forbidding their combination again.

Groove can mainly be to advance along axial direction, but also can be the for example similar a kind of ultra thick screw thread of tilting.

In the bases of hub, also in other words, in that position that water flow path is upwards outwards dispersed, the corresponding conical surface that forms on the side surface through hub possibly deflect, and gets into the spray head enclosure.The sort of deflection also can be mixed into a curved surface that ends in the sagittal plane through the lateral surface that for example guarantees hub and little by little carry out.The sort of curved surface, transition gradually or deflection also possibly exist or take place, and no matter whether there is axial water guider.

If use and to consider needs, then deflector also can have discontinuous passage, if said discontinuous passage exists, can be straight with the longitudinal axis of hub vertical, straight with tilt or bending.

The guider that can be aligned on the deflector axis can be installed in the shell of spray head, that is to say, is installed in the upper reaches in the jet disk, is predefined in the even distribution that produces the current of inflation on the whole surface of jet disk like this.Each guider can be positioned on the inwall of shell for example or exist on the plug-in unit in the enclosure.

In relevant detailed description of the present invention, spray head can be divided into two zones from its surface with outlet opening of coming out and one except a shell, jet at least, also has a selector.That selector can will be intake and between one first district and one second district, changed.Also be provided with one water is directed to the water inlet in the spray head.Air inlet is provided for the purpose to the water jet inflation that exists in the spray head.Air inlet give to get into the water inflation of spray head, and a position that kind between the surface that water inlet and jet therefrom come out is done.Air inlet can be acting and inoperative, that is can between a kind of state that works state and do not reinstate, change.According to the present invention, selector and air inlet interconnect like this, and during with convenient driving selection device, air inlet will be transformed into inoperative state from the state of working, and perhaps be transformed into acting state from inoperative state.Therefore no matter when it is transformed into second district from first district, and air inlet all will change its state that works.In other words, according to the present invention, no matter when the driving selection device all is suitable for a kind of dual-use function; This also makes it obviously, and selector can be worked on the contrary, that is the work of no matter when air inlet is worked or inoperatively all is transformed into another district from a district.

The sort of method produces a kind of favourable double action.Drive two kinds of operations of a control device control.Especially, intake operation can through select Jiang Ge district to combine or when making it operate in their and combine accidental generation work or inoperative.

In relevant detailed description of the present invention, first district can be configured to the wherein form of a part on the surface that jet therefrom comes out, and first district can be the core on above-mentioned surface for example here.In this combination, second district can be the whole surface that jet therefrom comes out.For example; No matter when selector is set to the whole surperficial intake operation that second district or jet therefrom come out and can works; The advantage that has like this is that adding air or current are inflated a large amount of current that all will form to come out from spray head; If comprise a big area, because more a large amount of outlet openings is arranged, a large amount of current will be useful.

The advantageously available hand of selector drives.Can press the button, sliding part or analog be so that the driving selection device.If whole and especially big crust component can move with respect to the remainder of another crust component or shell, will be favourable.

Two districts or all districts can be connected on the water inlet through a distributor chamber, and above-mentioned distributor chamber supplies water to above-mentioned each district.Distributor chamber can advantageously comprise all district or the jet upstream surface side of therefrom coming out whole areas, and this will guarantee the good water supply in all outlet ports hole on the surface that all districts and jet therefrom come out.Selector can be constructed like this, works so that it is installed in the distributor chamber and in distributor chamber.When setting first district, it can be equivalent to the restriction of the scope of distributor chamber that area in first district.When being set to another district or second district, the scope of dispensed chamber can be adjusted to the area that adapts to another included district.When setting provides the scope on the whole surface that jet therefrom comes out, can eliminate the restriction of distributor chamber scope, so that it will comprise the four corner on the surface that jet therefrom comes out.

Selector can have a lid, and said lid is especially preferred to be such structure, so that the scope of its ability dispensed chamber.The scope of dispensed chamber can be easy to through guaranteeing that the upstream side that lid can paste the surface that jet therefrom comes out accomplishes.Preferably with that system sealing.The scope of dispensed chamber is preferably accomplished as lid through using a wall.Area on that wall to be included preferably forms that part of of area selected on the surface that distributor chamber therefrom comes out corresponding to jet.

In order to improve the sealing of system, a kind of sealing of shaping can be set.For example, a kind of sealing lip will be suitable for the sort of occasion.It can head on towards the seal at the upper reaches and incorporate in the distributor chamber of restriction, and in this case, the hydraulic pressure of rising will help its sealing function.

A kind of appropriate method that is used to make the surface that jet therefrom comes out is that selected for example a kind of elastomer of a kind of elastomeric material is used for such occasion, and above-mentioned elastomer can be a kind of rubber-like elastic body.Wall or lid can be placed on the upstream side of this jet dish, so that implement sealing function.The above-mentioned seal that stretches out advantageously can be formed on the upstream side of jet dish, will need not use seal separately like this.

Water advantageously joins in the spray head at the center, under any circumstance, all is to add near short-range being positioned at apart from one at the distributor chamber upper reaches, can on the surface that jet therefrom comes out, reach so the most uniformly to distribute.It is a kind of that air is imported spray head or makes air face toward the lip-deep center aerator that jet therefrom comes out also is favourable.Water advantageously can import from the upstream side on the surface that jet therefrom comes out or from the top of spray head.Aerator can pass through the centre bore on the surface that jet therefrom comes out, that is stretches into the shell that stretches into spray head from that side of surface that water therefrom comes out.

A passage can be set be used to import air, above-mentioned passage can pass through surface that jet therefrom goes out with in addition with this surface engagement, perhaps be installed in the surface near.Selector also can be connected on the water inlet or be installed on the water inlet.Under the situation of one embodiment of the invention; The surface that jet therefrom comes out can be moved so that change and start spray head with respect to water inlet; In this case, can use a baffle plate on the water inlet then cuts off or opens and be used to import the passage of air and the for example scope of dispensed chamber simultaneously of a wall on the selector.

Although that side of spray head that can therefrom come out through water of air that is import through the surface that jet therefrom comes out as stated is if the air court direction vertical with water inlet or water inlet come out being favourable from filling channel.Air utilizes the Venturi effect to import and will produce a kind of air and is blended in the turbulent flow in the water.Air also can use the sort of method during whole importing water, to distribute.

Under the one embodiment of the invention situation, water feed apparatus can have many apertures, and above-mentioned aperture can circularize distribution around center line, and each aperture advantageously can be an elongated slot here, so that comprising quickening discontinuous water jet.Because for example above-mentioned Venturi effect so the air in the inlet duct can directly get into the upper reaches of each aperture, can reach the abundant mixing of sky G&W like this.

The device that produces turbulent flow also can be set, and the device of said generation turbulent flow is positioned at from position that air gets into respect to the upper reaches of water (flow) direction.The two mixture of water and the air carried secretly will impact those and produce turbulent device, and said mixture for example can be got the form of multistage cascading, and will become more turbulence and mixing.The turbulent device of this generation advantageously perhaps centers on the passage distribution that is used to import air around the center line distribution of spray head shell.For example, they can form on the outer wall of passage, are tubuloses if be used to import the passage of air, and then under above-mentioned situation, it can be installed on the port of export of spray head.

The device that produces turbulent flow is except they produce the function of turbulent flow; Can also be configured to guarantee that the water that imports will be distributed on the gamut of the upstream surface side that jet therefrom comes out; Above-mentioned surface is enclosed in the distributor chamber, and perhaps deflection is led the water of branch with distributing.If the water generates of the importing of entering distributor chamber is similar to uniform distribution then is favourable.

The spray head that spray head proposed by the invention especially also can be used as a kind of side installation finds application.Owing to mix with air; So water jet obtains one than long scope; Under the surperficial vertical orientated situation of therefrom coming out with jet; This benefit that has in addition is that water jet will impact a main body of standing, and the said main body of standing is positioned at one and prolongs on the area apart from spray head a distance and desirable height place.Because it is to carry out from that side of surface that water therefrom comes out through the surface that jet therefrom comes out that air imports; So compare with the spray head that install the known side that does not have air to mix, the spray head that is shaped, arranges and install the side of spray head of future generation to install will be both uncomplicated also not difficult.

Of the present invention those with other characteristics accessory rights claims, this specification and accompanying drawing in will be conspicuous; The independent characteristics of included here each can they oneself individually or in an embodiment of the present invention or other zone and advantageously and the several characteristics of implementing in the patentable inherently variant get it and divide the form of combination to represent, for this requires patent protection to them.

The detailed description of sample embodiment

Fig. 1 and 2 illustrates according to a kind of spray head 11 of the present invention.Spray head 11 comprises a case body 12, and said case body 12 rests in the substrate 13 or is directed in the substrate 13.Spray head 11 is connected to through box nut 15 on the pipe joint 14 of a water, and the pipe joint 14 of above-mentioned water has a known ball head structure.The pipe joint 14 of water for example is placed on the ceiling.

Case body 12 is got the form of tubulose extension 17 basically, and said tubulose extension 17 is in extending below and sneak into wide extension 18.Substrate 13 is shaped in the same way, and above-mentioned substrate 13 also broadens downwards, forms an extension 24 simultaneously.

Rubber ring 20 inserts in the upper part of substrate 13.Ledge 22 also stretches out from substrate 13.Rubber ring 20 is provided for being sealedly engaged with the tubulose extension 17 of case body 12.Tubulose extension 17 also has the skewed slot 19 of some screw thread-like.Ledge 17 engages those grooves.Therefore case body 12 slides with respect to substrate 13 when rotation, finds out as knowing from the contrast of Fig. 1 and 2.Directly along center line compress with respect to substrate 13 and therefore slide housing 12 also can use the embodiment that some short grooves and protuberance assign to replace this screw thread-like so that regulate it.

The extension 24 of substrate 13 have one from its outward flange to the peripheral annular bump 25 that extends below.The accurate shape of above-mentioned bump can be found out in Fig. 2.Ring uplift part 25 is incorporated in the narrow profile of similar " V ".In the position shown in the figure 1, narrow profile provides a kind of sealing function, and said sealing function will more specify below.

Spray head 11 also has a front 27, and said front 27 joins on the case body 12 near case body 12 outer edge part.When the injection stream disk inserts, front 27 will be sprayed disk 29 and will be contained on its back.A kind of elastomer of jet disk 29 usefulness is made in the known manner, and has the nozzle of doing by mould and be used to form outlet opening 30.From Fig. 1 and especially as can beappreciated from fig. 2, the back of jet disk 29 is the plane basically.Circumferential lip 32 is the unique parts that form on 31 in the back, and can press ring uplift part 25, as conspicuous among Fig. 1.

Water inlet 33 runs through the pipe joint 14 of water and stretches into spray head 11.Water comes out from the bulb on the pipe joint 14 of water through the aperture 34 that distributes around center line, and gets into the upper part of distributor chamber 36, and the upper part of above-mentioned distributor chamber 36 is positioned at 17 inside, tubulose extension.Like what obviously find out from Fig. 1, because extension 24 sealed cooperation ring uplift parts 25 of pasting on jet disk 29 back 31, so water can only arrive those outlet openings 30 that are positioned at that zone.There is not other water flows route to exist.Especially, locking outskirt that is comprise the district B that distinguishes A.

If case body 12 shifts downwards with respect to substrate 13 with its extension 18, then vibration is left the back 31 of jet disk 29 with its ring uplift part 25 in extension 24.Distributor chamber 36 will be opened always and will comprise that then the aperture 34 from the water inlet 33 extends in the maximum possible scope of jet disk 29 back.Water will pass through all outlet ports hole 30 outflows on the jet disk 29 then.

And in this case, how lid 42 makes top aperture be slipped in the air duct 38 contrast from Fig. 2 and Fig. 1 can obviously be found out.Inlet duct will be opened like this, from the front of jet disk 29 or the front 27 of spray head 11, get into spray head or will get into distributor chamber 36.As what can find out, from air duct 38 above the air that comes out of aperture be incident on and pass the waterborne of aperture 34 ejection downwards, and roughly meet at right angles with it and to get in distributor chamber 36.Because the Venturi effect, the water of entering is with entrapped air.Certain mixing of water and air begins simultaneously.

The sort of water-air mixture is incident on the extension 46 that produces turbulent flow, and said extension 46 forms on the lower part of air duct 38 outer walls.As what can find out from the chamfered edge of extension 46 that produces turbulent flow, the water that is incident in from above on the chamfered edge will be to side deflection, that is get in the sidewall of distributor chamber 36.The turbulent flow in water-gas mixture or the mixing of water-gas mixture also will take place.In addition, can add similar extension or thin neck in this position.The extension that produces turbulent flow preferably is shaped with the form of multistage cascading.The covering of each cascading formula level can mate chamfered edge.

As what from each accompanying drawing, can find out, the profile of external appearance matching case body 12 extensions 18 of substrate 13 extensions 24.Step in the extension 18 is provided for the space of extension 24 so that get into above-mentioned step.It is the scope of dispensed chamber 36 outer annular part also, the water that therefore is supplied to all outlet ports hole 30 in position shown in Figure 2, that is when water supplies to the maximum possible scope of jet disk 29 approximately equal.

Like what obviously can find out among Fig. 2, except between the first district A and the second district B, and between inflation and the unaerated outside more or less the discontinuous conversion, in some cases, at least a function that is shaped is so that it can controlledly continuously also be feasible.Especially, aerator can be applied to the sort of occasion.The associated aperture of upper part of covering shape and the air duct 38 of 42 lower parts can be constructed like this; So that case body 12 will produce the opening of a continuous inlet duct 40 through the air inlet 44 of the air routing on its whole stroke with respect to the motion of substrate 13, the situation when the sort of here opening will be opened than distributor chamber 36 is discharged quickly.

Fig. 3 illustrates a kind of and the similar spray head of Fig. 1 and 2 illustrated embodiment, but it does not have selector.A kind of insertable plate 50 is installed in the upper reaches of jet disk 29, and above-mentioned plate 50 has and jet disk 29 upper outlet holes 30 corresponding bore holes 51.Insertable plate is with a kind of harder plastics manufacturing of plastics used when making jet disk 29.Wherein, the purposes of insertable plate is that elastomer jet disk 29 is remained on its front 27 and remains in the substrate 52 of shell, and the inclination angle of planning to prevent each nozzle so during installation or change during operation.

Insertable plate 50 has some discontinuous ribs 53 on its upstream side, above-mentioned rib 53 segments the space between the rear wall 52 of jet disk and shell again.The sort of segmentation is planned to lead in the enclosure and is guided the jet of each inflation.

Other details, especially relating to the details of supplying water and air will be discussed below.

Fig. 4 illustrates another embodiment of spray head, and above-mentioned spray head is shaped in this case especially simply.The shell of spray head comprises a rear wall 52 and a kind of very simple jet disk 54, between them, forms a smooth a little disc distributor chamber 55.Sealing is near its edge, to carry out, and is applied in the seal that exists in the groove 56 on its rear wall 52, and above-mentioned rear wall 52 compresses the upstream side (referring to Fig. 6) of jet disk 54.In this case, whole jet disk 54 is all used harder plastics manufacturing, so that the gradient and the shape of the aperture 57 that jet therefrom comes out are remained unchanged.As as can be seen from Figure 5, Fig. 5 illustrates the view that shell shown in Figure 4 draws in the ratio of amplifying, aperture 57 that jet therefrom comes out be tilt with tapered.

Because pipe joint is connected to the spray head shell shown in Fig. 3 and 4 corresponding on the waterline shown in Figure 1, these details need not further specify.Under the situation of Fig. 3 and 4 illustrated embodiments, the water that gets into through inlet will be incident on (referring to the diagrammatic sketch of the magnification ratio that shows among Fig. 7) on the apertured disk vertical with water (flow) direction 60 now.Apertured disk 60 is circular peace, and has the circumferential bulges part 61 of extending downstream.The diameter of inlet mesopore 62 is much littler than the diameter of apertured disk 60.Be arranged in circular hole 63 on the apertured disk 60 around its circumference arrangement.If therefore water arrives aperture 63, then it must leave aperture 62 at first to extrinsic deflection.

Aperture 63 in the apertured disk 60 is split into discontinuous water jet with the moisture that gets into.Be directly installed on the downstream of apertured disk 60 cores at the inflation hub 64 that exists in the two embodiment illustrated in fig. 3 and embodiment illustrated in fig. 4.Fig. 7 illustrates the embodiment shown in Figure 3 that draws in the ratio of amplifying.The upstream extremity of inflation hub 64 is got the form on a kind of plane terminal surface 65, and above-mentioned terminal end surface 65 is positioned at short distance on a side or the opposite side of apertured disk 60.Air through the centre bore in the inflation hub 64 40 imports is aimed at water jet, and it is streamed that above-mentioned water jet has been segmented into a kind of very narrow plane in advance.The Venturi effect that imports air stream in its confluce is owing to the high flow rate of aperture 63 downstream water jets rises.

Aeration jet advances to the substrate 67 of hub along the cylindrical side surface 66 of inflation hub 64 then, and its side surface expands herein, forms a kind of truncated cone simultaneously, and it is about 45 ° that the said truncated cone has a half-angle.The sort of taper extension 67 compresses insertable plate 50, and water is outwards flowing on a planar radial on the above-mentioned plate 50 then.The angle of deflection plane 68 can be in 10 ° of-80 ° of scopes.Crooked gradually transformation also is feasible.The sort of arrangement for deflecting makes the current of inflation diametrically to extrinsic deflection, and entering is installed in the distributor chamber in jet disk downstream.

Fig. 8 illustrates 600 fens simple top views of apertured disk, and said apertured disk 60 has 8 apertures 63.Under the situation of practical embodiments, the sum of aperture 63 is greater than 8, so that produce the water-jet fluxion of maximum possible.All apertures 63 all are positioned near the circle apertured disk 60 circumference.

Fig. 9 illustrates the side view of inflation hub 64 shown in Figure 7.Obviously, deflection plane 68 all extends around its circumference.Under the situation of illustrated embodiment, its side surface 66 is smooth herein, as its terminal end surface 65.

Figure 10-12 illustrates a kind of embodiment that inflates hub 164, and said inflation hub 164 is a kind of improvement of inflation hub 64.Several radial passages 70 extend to its lateral surface from the inside of hub 164, above-mentioned radial passage 70 is shaped on its terminal end surface 165.The axial passage 71 that is formed by groove is being present on its lateral surface with 70 identical positions, radial passage.All incorporate in the axial passage 71 each radial passage 70.On deflection plane 68, form other passages 72, they extend other

radial passage

70,71, and the degree of depth of passage 72 reduces (referring to Figure 10) towards the bottom direction of deflection plane 68.This method will guarantee that discontinuous air-spray will originate from the terminal end surface 165 of inflating hub 164, and above-mentioned air-spray will be incident on by aperture 63 then on the formed water jet in the position that forms them.

In the top view of Figure 11, the passage 72 in the deflection plane 68 is still straight upwards being orientated with the footpath.Yet Figure 13 and 14 is illustrated in the respective view under the other inflation hub situation, and the passage 172 in the deflection plane 168 is arches or crooked here, makes aeration jet have a gradient like this, and aeration jet will keep above-mentioned gradient when the inflation hub comes out.The sort of method will produce turbulent flow in the aeration jet in the distributor chamber of spray head shell.

Under embodiment situation shown in Figure 14; Figure 14 illustrates a kind of deconvolution of inflating the side view of shell dish; Each passage 171 tilts and similar a kind of ultra thick screw thread with respect to its longitudinal axis; Rather than resemble the embodiment shown in Figure 12 be straight be parallel to longitudinal axis, will in aeration jet, early begin to produce eddy current like this.

Inflation hub 164 shown in Figure 10 can for example be arranged like this, so that the joint between each radial passage 70 in its plane of terminal end surface 165 will contact the downside of apertured disk 60, causes producing distinct air-spray so then.Yet, also can keep certain clearance, so that 70 position can produce a kind of preferred field of flow in the radial passage.

About the said mistake of guider, based on the inflation hub, also may be advanced in the distributor chamber.For example, the aperture that comes out of the jet straight extension form that can get passage 72,172 ledges is arranged.Yet not every passage 72/172 all must have identical curvature or identical direction.It can guarantee further to get into distributor chamber to the aerated water jet of extrinsic deflection, come out from the substrate of inflation hub along straight route, and those aerated water jets of waiting to deflect into more the aperture that therefrom comes out near jet produces more turbulent flow.

Owing to use the expression of simplifying, the embodiment shown in Fig. 3-14 does not have demonstration to be used for the conversion equipment of between the various surface regions that jet therefrom comes out, changing.They do not have demonstration to be used for the device that conversion left and closed by aerator yet.However, have at spray head under the situation of this conversion equipment, be used to produce and keep the measure of included discontinuous aeration jet also be certainly feasible with gear to actual circumstances.The present invention specially recommends the sort of clearly.
