Description
The present invention relates in general to sparger and the method that is used for spray fluid or flow-like material, more particularly, relate to a kind of improved type sparger that is used for this class fluid, it has enough flexibilities, can be configured as various required sprinkling forms, do not produce deleterious effect and can convection cell do not flow therein, and can keep its specific sprinkling form.
Although the present invention has very strong effectiveness for spray pressure liquid and aerosol foam, especially those materials that form by liquid polyurethane prepolymer or latex, but it is practical too for spraying other fluid or flow-like material, and regardless of their chemistry and physical property, for example adhesive agent, chink, cleaning agent, lubricant, insecticide, solvent and analogue.The present invention can also be used for sprinkling food class material, for example cake filling material, whipped cream and decoration frosting.
For example, above-mentionedly outwards spray cloth fluidised form polyurethane prepolymer and latex is finished by gaseous state volatilizer or foaming agent from pressure container, when opening dispenser valve, these volatilizers compressing liquid outflowing containers under pressure.Sometimes, pressure container contains central dip tube, and it stretches to container bottom at internal tank, so volatilizer shifts liquid onto container bottom downwards, enters in the dip-tube and flows out dispenser valve.In this structure of container, volatilizer by dip-tube with the liquid containers for pushing out.So, must be noted that the orientation that will guarantee container makes dip-tube be under the liquid level all the time.Otherwise volatilizer will spill from container by dip-tube and make the user baffle.Thereby this series products only limits to be used in container and is under the situation of determining the orientation, generally is to be in the basic vertical orientation of promptly erectting, and increased like this to being difficult to reach the difficulty that this class I liquid I is put in the zone.
Container above-mentioned can adopt rigidity or the semi-rigid tubule that links to each other with dispenser valve, comes spraying liquid by this tubule.Rigidity spray cloth tubule has made things convenient for the use of this class container by " ranging coverage " that increases the user.Yet this rigidity tubule does not have flexibility and can only keep the straight form of mono-.The user still is restricted when these liquid of spray cloth, and this is to be in basic vertically orientation owing to need to keep to spray the cloth container, thereby has limited the ability that the user is sprayed these liquid of cloth.
But semi-rigid spray cloth tubule has been widely known by the people and has been applied to above-mentioned spraying liquid.This spray cloth tubule can be bent a little by the user, but can not keep its shape after the bending, and the user must with the hands come spraying liquid: he must grip container with a hand, firmly sprays the cloth tubule with the gripping of another hand in spraying liquid.Although this tubule can bend a little, but still must keep spray container to be in vertical orientation, and impossible singlehanded spraying liquid, this is firmly spray the cloth tubule with the guiding flow direction because the user must grip with his another hand.Therefore, be impossible singlehandedly spray this class I liquid I with this semi-rigid tubule, and with the hands spray usually entail dangers to user's safety, especially true when the user stands on the ladder.
The pressure container that another kind is used to spray the cloth pressure fluid may be equipped with and be known as Clayton's valve that can tilt.Such valve stretches out a bit of distance from container top above container, and stretches out a bit of distance to internal tank.This valve opening and allow fluid to flow through when inclination.Yet,, volatilizer is remained on liquid level and the valve for drain pressure liquid from this container effectively.Thereby, must use this container with vertically basic and inverse manner all the time, thereby volatilizer is remained on the valve, flow out valve openings with compressing liquid.
Even use rigidity recited above or semi-rigid spray cloth tubule, this class container also must remain in vertical and inverted orientation, and the user must make and with the hands comes spray fluid.If the user for the position that changes spray cloth tubule in spraying liquid mobile containers, he may make part or the leakage of most of volatilizer, this will make the operator whole spray liquid can't be come out.Therefore, though rigidity and semi-rigid spray cloth tubule may increase the fluid spray cloth scope of some these class pressure containers, they do not overcome its fluidsupply container structure the intrinsic sex-limited and shortcoming of owning administration.
In another kind of spray liquid was used, the structure of fluidsupply container was modified, to solve above-mentioned spray cloth orientation problem.For example: pressure liquid container can be equipped with internal pocket, but its be arranged in container and hold spraying liquid, it also is communicated with dispenser valve on the container.Volatilizer is contained in the bag peripheral region and acts on bag to oppress liquid through the dispenser valve flow container in container.Although internal pocket can reduce above-mentioned volatilizer leakage problem effectively, but still has certain problem.One of problem is that this class container only uses rigidity above-mentioned and semi-rigid spray cloth tubule, therefore still needs the sprinkling direction of both hands sprinkling with guiding liquids.Thereby this class container forbids user's one hand to spray, even also be like this under the situation that is difficult to reach regional in sprinkling.Second problem is the internal pocket complex structure and needs to increase the assembling manpower, so just increased the total cost of container and spray assembly thereof.In addition, when being used to spray particular fluid for example during the fluidised form polyurethane prepolymer, this class prepolymer solvent for use and/or foaming agent have chemical corrosion, are easy to destroy the integraty of bag after long-time.Therefore, must consider the material compatibility of this class container, and the shelf life of this class container shortens greatly.
In another is used, and as to be published in No. the 5th, 441,181, the US Patent in August 15 nineteen ninety-five described, pressure liquid container is equipped with internal piston, and container is divided into two different compartments effectively, a receiving fluids, another holds volatilizer.Although can spray effectively, this construction expenditure is higher and must be noted that the manufacturing and the assembling of piston, guarantee effectively sealing between piston and the wall of container, leaks in the liquid to prevent volatilizer.This piston type container draws tubular type and Clayton and can compare by the inclined valve container with above-mentioned, and manufacturing expense is higher.
Also described some in this area and liquid container was provided other trial that to locate nozzle.Be published in July 20 nineteen twenty-six US Patent and described a kind of segmentation metal tube the 1st, 593, No. 016, its outside is wound with the reinforcement metal silk.The assembling and the Packing Fee of this structure are higher, and ordinary consumer uses some difficulty.
The US Patent that is published on April 2nd, 1991 has been described a kind of flexible nozzle that is used on the adhesive receptacle the 5th, 004, No. 128, and wherein the nozzle body structure is modified, and one section is done out fold so that can handle this section nozzle.Yet the inside fold of this types of nozzles may influence liquid flowing in nozzle, and this nozzle can not keep its crooked shape under the pressure of institute's spraying liquid owing to increased the resistance of flow of liquid.
The US Patent that is published on June 25th, 1996 has been described for the 5th, 529, No. 226 a kind of by many synthetic flexible spargers, and it is bearing on the fluid container by an outside coupling link.Owing to there are many, the manufacturing and the assembly expenses of this multiple-piece sparger are higher.These sheets may scatter and make the user baffle in connection procedure.
Therefore the invention relates to a kind of flexible sparger, its structural form is the hollow flexible pipe, be used for spray pressure liquid, wherein sparger can be deformed into various forms and keep its form, make it possible to come singlehanded spray cloth liquid with this sparger, thereby be convenient to the user liquid is sprayed cloth to being difficult to reach the zone, and its used mode can not influence liquid and flows in sparger.

Figure 1A-1C shows known pressure liquid container 20, the feed flow source of dress liquid 22 in it has, and this container of general in the art use sprays cloth foamed glue emulsion attitude cmpd, is used for sealing, insulation and other purposes.Also contain volatilizer or foaming agent 24 in the container, the user can become liquid or foam with liquid spray cloth wherein, is typically to be droplet-like.
For the ease of using this container 20, rigidity sparger tubule 32 can be housed to prolong the ranging coverage of nozzle.In some cases, used sparger tubule is semi-rigid sparger tubule 33, and the operator can be with the spray cloth direction of its bending with the guiding fluid.This semi-rigid sparger tubule 33 can not keep its shape, must be gripped to keep its orientation with a hand by the operator, and operator's another hand must grip container 20 simultaneously.The range of movement that has been shown in dotted line semi-rigid sparger tubule 33 among Figure 1A-1C, and the position of both hands when showing the user and operating and grip the sparger tubule.
A problem in use rigidity or the appearance in 32,33 o'clock of semi-rigid sparger tubule is: volatilizer 24 can be missed from container 20, and this is to spray in the process of cloth liquid 22 owing to requiring great effort the user, and container 20 intrinsic orientation limitation own are caused.The leakage that is to be understood that volatilizer 24 can make the user the 22 spray cloth of the whole liquid in the container 20 can't be come out.Figure 1B shows the container 20 that is in level orientation, because the orientation of container 20, the opening 30a of its inner dip-tube 30 is lifted to more than the volatilizer height.Fig. 1 C shows the container 20 that is in another well azimuth, and its dip-tube opening 30a is lifted to more than the height of volatilizer 24.
From to the research in these two orientation as can be seen, the user is limited in the certain movement scope that container may be directed, this is because the structure of rigidity or semi-rigid tubule 32,33 and container 20 causes.The user need make with the hands could move semi-rigid tubule 33, so that spray cloth and storing liquid.Under some situation shown in Fig. 1 D, make so with the hands to make the user can't get at the position that those must spray cloth liquid.From as can be seen to the consideration of Fig. 1 D, be illustrated as the obstacle of pipe 38 or hinder user's one-handed performance container 20, or make bimanualness very difficult, otherwise can't accomplish and produce danger exactly, especially true when the user stands on the ladder 39.In Fig. 1 D, the user attempts in the slit 80 places deposition foam seal glue drips, and this slit is between the top of beam slab 81 and foundation wall 82.
Be difficult to reach the zone at this, the user may move to container 20 more comfortable spray cloth orientation, for example level orientation shown in Figure 1B.If he so makees and opened spray cloth assembly 26, then from container 20, will overflow volatilizer 24 rather than liquid 22.
These limitations restrict the user spray the ability of cloth liquid and influenced other structure of container.Referring now to Fig. 2 A, there is shown totally with the 40 another kind of known vessel of representing, the volatilizer 43 that liquid 42 wherein is housed and liquid 42 is exerted pressure.Such container 40 has in the art that to be known as " Clayton " be tiltable spray cloth valve 44, an end 46 of its propelling container 40.This spray cloth valve 44 comprises short nozzle 47 and a pair of outwardly directed unlatching arm 48, and the user can should open arm with finger control.Pull and open arm 48 and will cause spraying cloth valve 44 and tilt and open.After opening, valve 44 can make liquid 42 under the pressure of volatilizer 43, enter valve openings 44a.
Fig. 3 shows the third pressure fluid vessel 60, as issues in No. the 5th, 441,181, the US Patent in August 15 nineteen ninety-five described.The feed flow source and the volatilizer supply source 62 that can spray cloth liquid 61 are housed in this container 60.Liquid 61 and volatilizer 62 are separated mutually by piston 64, and this piston contains annular piston skirt 65, and its edge 66 around piston 64 stretches and contacts with the inside face 68 of wall of container 69.The spray cloth valve 70 that is illustrated as traditional fog-spray nozzle 72 is positioned at an end of container 60, and with container 60 internal communication.Container 60 also can be equipped with rigidity sparger tubule 73 or semi-rigid sparger tubule 74.
As described in above-mentioned the ' No. 181 patents, adopt this piston-type structure of container, must be very careful with assembling to the design of container, keep closely and the failure-free sealing to guarantee piston 64 and wall of container 69.Sealing leaks out from spray cloth valve causing piston 64 to make volatilizer 62 pass liquid 61 if go wrong.Although there is leakage problems, this container 60 is compared with the previous container of discussing and is still the processing charges costliness, and needs extra labour power when assembling, has therefore improved total cost.
The invention provides a kind of sparger, it has overcome shortcoming above-mentioned and limitation and has fully improved the range of movement of spray liquid, and has significantly reduced cost.Referring now to Fig. 4, the flexibility of constructed in accordance with the principles can formalize (or elastically deformable) sparger totally with 100 expressions.Sparger 100 is elongated and hollow, has the central fluid channel 101 of extending along sparger 100 total lengths, and this passage is surrounded by continuous sidewall 102 and forms.The setting element 103 that is illustrated as elongated metal wire 104 in a preferred embodiment is embedded in one section sparger sidewall 102, and extends along the total length of sparger 100 in the mode of the internal fluid channels 101 that is basically parallel to sparger 100.
An importance of the present invention is, sparger 100 can with flexible material for example plastics extruding form, be preferably and adopt for example polyvinylchloride (flexible PVC) of flexiplast, it is easy to around metal filament 104 extrusion moldings to avoid because molded sparger 100 and need raising the cost.Metal filament exists as the part of sparger 100, makes the user easily sparger 100 is positioned to any required form or form, and in order to spray cloth pressure fluid, and relocatable becomes difformity and continues spray fluid when needs.In addition, the position of setting metal filament 104 in the sidewall 102 of sparger 100 makes fluid passage 101 have basic uniform cross-sectional area, can promote fluid to flow therein like this, rather than resemble the setting metal filament and be positioned at and hinder flowing of fluid the centre gangway 101 of sparger 100.
Setting element 103 makes sparger be shaped by the user and reshape to be any required form, thereby the range of movement of the spray cloth assembly of the pressure container that adopts this setting element is enlarged.Setting metal filament 104 also can keep the shape after sparger 100 setting valuably, make the user can also be scheduled to spray cloth surface mobile containers in the edge by enough one-handed performance pressure containers this moment, make container be in preferential direction simultaneously, the Clayton of having for example shown in Figure 10 can inclined valve container be in vertical orientations, and draw tube container shown in Figure 11 and be in vertical orientations.So, by using sparger 100 of the present invention, can avoid harmful leakage of volatilizer, and the user can be only gets at those and be difficult to reach crackle, space, crack and substrate in the zone with singlehanded, make pressure container outwards spray cloth liquid subsequently with preferred spray cloth orientation.
Form sparger sidewalls 102 (and by element 103 and 102 while of the sidewall extrusion molding of will formalizing) by pushing around the element 103 that formalizes, the metal filament 103 that formalizes is integrated in the sparger 100, and synthetic sparger is an one-piece construction.Adopting diameter is the diameter of 0.04 inch setting metal filament 103, sparger 100 when being about 0.25 inch and its inner passage diameter and being 0.17 inch, can obtain optimum efficiency.Should be appreciated that these sizes only are examples, and by adopting bigger setting metal filament of diameter or the employing second setting metal filament 103a as shown in figure 12 can control the flexibility of sparger 100.In addition, used setting element 103 circular metal silk 104 not necessarily.As shown in Figure 6A, also can adopt the band shape setting element of making by dull and stereotyped wire rod or similar material 105.The setting element can also adopt high density with shape memory and retention performance but pliable and tough plastic material.
With top discussed and prior art as shown in Fig. 1-3 in rigidity and semi-rigid spray cloth tubule compare, this single-piece sparger has bigger range of movement, or has identical with it range of movement at least.Fig. 5 A shows two the another kind of forms of turning round that have that sparger 100 may form.Fig. 5 B shows a kind of more complicated form, adopts curved and right side time curved towards the sparger outlet in the drawings of three masters.Fig. 5 C shows the sparger 100 that is configured as complex curve, wherein is formed with a plurality of bendings.
The shape freezability of sparger 100 makes can the one-handed performance liquid container, as Figure 13 and shown in Figure 14, wherein sparger end 109 is crooked, can liquid distribution be arrived some zone by penetrating, and these zones are positioned at electric connection box 151 open space 150 behind shown in figure.
Compare to three-piece construction with above-mentioned two, use individual construction can also quite save cost, especially when sprayer all the more so during towards current consumption market.In addition, because its single-piece characteristic, it neither needs existing nozzle to spray cloth assembly to assemble, and does not also need manually to insert container package.In the assembling process of container package, can realize that automation assigns sparger 100, thereby can save the total cost of container and spray cloth assembly thereof.
As clear demonstration the among Fig. 8, the sparger 100 that can formalize is directly installed on the end 110 of the nozzle 112 of spray cloth assembly 113, and this assembly is installed on the pressure container 115.In this regard, nozzle 112 can have the reduced diameter portion position, this position diameter equals or is slightly larger than as the Fig. 6 or the inside diameter D of sparger 100 as shown in Figure 8, and the external diameter of nozzle 112 can be slightly larger than the internal diameter of sparger 100, in order that form slight force fit between two elements.The hollow recess 117 that spray cloth assembly 113 can have around nozzle 112, it is formed in the head 118 of spray cloth assembly 113.This recess 117 is admitted an end 120 of sprayers 100, and the side of sprayer 100 is adjacent to the wall that sprays cloth assembly head 118 in should the zone.
Shown in Fig. 8 A, it is head 118 that spray cloth assembly 113 comprises housing, and it is suitable for being assemblied on the top of fluid container 115.Housing 118 contains nozzle 112, and it has hollow horizontal segment 122, and this section is communicated with hollow vertical section 123, and this vertical section terminal 124 directly is communicated with the valve of fluid container 115.Nozzle 112 is bearing in to be opened in the member 125, and this component forming has terminal chucking position 126, can be meshed with the inner groovy 127 of sprayer housing 118.Engagement between terminal chucking position 126 and the housing 118 makes unlatching member 125 tighten position 126 motions around end, that is: swing up and down.Trigger piece 128 forms in to be opened on the member 125, is in the position that the user can pull with finger.Push trigger piece 128 and will make and open member 125 and move downward, it makes the vertical pipeline section 123 of nozzle 112 move to again to form to open with container valve and contacts, thereby makes fluid can flow through valve, nozzle 112 and sprinkler pipes 100.
