By providing a kind of design very simple and generally comprise and be combined together the device that is no more than 6 building blocks that separate that forms the spray nozzle device after the assembling, spray nozzle device of the present invention has solved the above-mentioned bad problem relevant with some traditional pump action spray nozzle devices.In a preferred embodiment, described device comprises only 3 building blocks, perhaps more preferably, comprises two building blocks that separate, and perhaps even more preferably, described device is formed by single, integrally formed building block.For term " building block that separates ", our meaning is not connect in any way between the each several part, and promptly they are not whole form (still, each building block that separates can comprise one or more global facilities or part) each other.The key that reduces building block quantity is whole all essential feature that form in apparatus main body.For example, inner room, import, induction valve, outlet and drain valve all form by main part limitation, thereby reduce the increase to needs and all parts that bring thus and the assembly cost of each separate parts.
The outlet of described device is fit to produce spraying by any suitable device well known in the art.For example, the outlet opening of outlet can be tiny hole, and it is configured to make under pressure the fluid breakup by it to become drop.
Outlet preferably includes outlet opening and described chamber is connected to exit passageway in the described outlet.Described drain valve preferably is arranged in the described exit passageway.Particularly preferably be, described exit passageway comprises that one or more interior spray change structure (internal spray-modifyingfeatures), and it can reduce the size by the drop of spray nozzle device distribution during use.Interior spray in exit passageway changes example of structure and comprises one or more expanding chambers, one or more minor air cells, one or more internal spray hole (can in exit passageway, produce the spraying of the fluid that flows through) and one or more venturi chamber (venturi chamber).Be well known that to comprise or comprise altogether above-mentioned feature separately that they help to make during use the drop that flows through exit passageway to decompose or " atomizing ".Netted effect is to produce more tiny spraying in the exit of spray nozzle device.These spraying change structures and the effect that can give the characteristic of the spraying that produces are known in the art, for example have been described in international patent application no WO01/89958, and the full content of this piece document is hereby incorporated by.Should be realized that the upstream that drain valve is arranged on exit passageway and outlet opening guaranteed that fluid enters exit passageway with enough power, be used for liquid and resolve into drop and form spraying.
Device main body
Chamber by described main part limitation can be limited between the two or more interconnective part of main body.Particularly preferably be, the chamber of described spray nozzle device is limited between two interconnective parts, and it can be to be combined together to limit the independent formation parts of a chamber, perhaps more preferably, and the be integral with each other building block of an integral body of two parts.In the latter case, two parts preferably are connected to each other by hinge or folding Connection Element, and described hinge or folding Connection Element can make two parts molded in same mould jointly, contact with each other then to form described chamber to limit.
In a preferred embodiment of the invention, outlet comprises drain valve, outlet opening and described drain valve is connected to exit passageway on the outlet opening, limits at least two interconnective parts that form described chamber and also preferably limit at least a portion exit passageway.More preferably, two interconnective parts form drain valve between them, and also limit whole exit passageway of formation and outlet opening.
Described exit passageway preferably is limited between the adjacent surface and the relative adjacent surface in another part in one of them part.One or more adjacent surfaces preferably include one or more formation groove and/or recess thereon, and it limits exit passageway when adjacent surface contacts with each other.More preferably, each adjacent surface comprises formation groove and/or recess thereon, and its alignment is to limit exit passageway when adjacent surface contacts with each other.Described groove and/or recess preferably extend to the opposite edges of adjacent surface from described chamber, when each adjacent surface contacted together, outlet opening was limited to the end of exit passageway.In a preferred embodiment, one or more sprayings change structures and are present in the exit passageway, and described structure also forms by the recess of alignment or other form that is formed on each adjacent surface, as the same with description shown in the international patent application no WO01/89958.
Two parts of main body can be permanently fixed together by for example ultra-sonic welded or thermal weld.If pedestal and top are installed or welded together, they are preferably made by compatible material so.But as previously described, it then is preferred forming main body by single kind material.
Alternatively, in the following time of situation without any welding, two parts can be configured to each other tightly/have opposing ground and cooperate to form nozzle (for example, by the connection that is clasped).For example, the edge of a part can be configured to fit in another part institute retaining groove to form spray nozzle device.
As another selectable scheme, two parts can link together in mould, then the material that is fit to of plastics or other can overmold built in junction that two parts link together.This can obtain by molded two parts of while in a mould, in mould they is joined together to form spray nozzle device, then will be around they molded appropriate plastic material, so that two parts are kept together.
In certain embodiments, two parts keep being connected to each other together releasedly, so that they can separate during use, so that clean described chamber and/or outlet.
More preferably, two parts of the main body of the spray nozzle device of qualification formation chamber are base part and top.Base part is preferably by suitable device, as screw thread or be clasped and be affixed on the opening of container.In addition, limit a part of main body that forms described chamber except forming, in a preferred embodiment, described base part also preferably limits a part of exit passageway that forms import and lead to outlet opening from described chamber.
Top is fit to be coupled on the pedestal, thereby in a preferred embodiment, between them, they limit and form chamber, drain valve, exit passageway and/or outlet opening.In some preferred embodiment of the present invention, pedestal and top also limit and form oral pore.Described top also is preferably formed the elastically deformable part that limits the main body that forms described chamber.
Material
The main body of spray nozzle device can be made by any suitable material.
In a preferred embodiment, main body comprises two interconnective parts that are combined together with qualification formation chamber, and described two parts can be made by identical or different material.For example, one of them part can be made as the plastics or the elastomeric material of elastically deformable by the deformable material of flexible/elastic, and another part can be made as rigid plastics by hard material.It is preferred that these embodiment belong to for some application, because the deformable material of flexible/elastic forms the elastically deformable part of the main body that limits described chamber, and it is easy to the extruding by the operator, so that the fluid that is present in the described chamber sprays with the form of spraying.Flexible material also provides a kind of sense of touch of softness for the operator.Body portion is preferably formed by rigid plastics, and top is formed by elastic deformable material.These embodiment can realize by following method, being about to two parts carries out molded respectively, then they are joined together to form the spray nozzle device of assembling, perhaps in same mould, use secondary injection method of moulding (bi-injection mouldingprocess) to carry out molded two parts.In the latter case, two parts can simultaneously moldedly be combined together in mould then, and perhaps selectively, a part is at first molded by first material, and the second portion molded by second material can be molded directly in the first.
As selectable scheme, two parts all can be formed by hard material or flexible material.Hard material and flexible material can be any suitable materials, and spray nozzle device can be formed by these materials.For example, it can be by the such metal material of aluminium foil, and perhaps the such flexible material of rubber forms.Yet described device main body is preferably formed by hard material or soft plastic material fully.
The nozzle of pump action is preferably formed by single kind hard or flexible plastic material.
Term " hard plastics " refers to following plastic material as used herein, and it has high rigidity and high strength after molded finishing, but it can also can provide more flexible or elastically deformable in the part by the thickness that reduces plastics.Therefore, can provide thinner parts of plastics to limit at least a portion main body that forms described chamber to form, this part main-body structure becomes elastically deformable.
Term " flexiplast " refers to following plastic material as used herein, thereby its intrinsic energy flexible/elastic deformable can make the elastic displacement of at least a portion main body to be easy to the compression of described chamber.The flexible degree of described plastics depends on the thickness of the plastics in any given area or zone.For example, in these " flexiplast " materials use preparations in hair cleaning bottle or shower glue container.In the manufacturing of spray nozzle device of the present invention, the part main body can be formed by thicker plastics, and providing structure required hardness, and other parts can be made up of thin plastics, so that required deformable characteristic to be provided.If when needing extra hardness in certain zone, just need thicker framework, generally be called ribs.
By the device main body that forms from single kind material, its advantage is that whole spray nozzle device can carry out molded with the one-off pattern method for making, be described further below in single mould.
Particularly in a preferred embodiment, promptly two parts are whole forms and is connected to each other by folding Connection Element or hinge, form the spray nozzle device of assembling so that the contact body portion can be swung in top, plant the assembling that spray nozzle device that material forms does not need a plurality of parts that separate by single.In addition, the spray nozzle device that is formed by single kind material provides two parts welding (as by heat or ultrasonic wave) possibility together, perhaps, if plastic material is a hard plastics, can between top and pedestal, just forms be clasped (snap-fit) so and connect.Select the latter that top and pedestal are disconnected for periodic the cleaning.
For the thumping majority applicable cases, spray nozzle device need be made by hard material, so that required intensity to be provided, and two parts are clasped or weld together.In these cases, only when certain minimum threshold pressure of effect, the deformable segment of main body just tends to distortion, and this makes pump action more as the ON/OFF effect relevant with the spray nozzle device of traditional pump action.Yet, in some applications, can the preferred flexible material.
The main part that is configured to elastically deformable can be relatively thin hard plastics, and it does the time spent when being under pressure, and strain when removing the pressure that is acted on, can be got back to the initial elasticity voltage biasing structure then.Selectively be, the described part of described main body can comprise by deformable segment around roughly hard part, thereby when the pressure that affact on this hard part makes the elastically deformable center on partly be out of shape, thereby can make described hard part move and compress described chamber.For example, the similar bellows of strain part that is centered on, be that hard part is centered on by deformable side wall, described sidewall comprises a plurality of folded section of rigid plastics, its structure can make when making pressure being affacted the hard part sidewall the folded section elastic compression together, to reduce the volume of chamber.In case when removing the pressure that is acted on, described sidewall turns back to their initial structures.
But in all cases, each adjacent surface that limits the exit passageway that forms outlet is preferably formed by hard plastics.Though the flexible/elastic deformable material can be used in this purpose, the existence that changes structure owing to present any spraying need accurately be formed by rigid plastics usually, so they generally are not preferred.Therefore, in some embodiments of the invention, one that limits in two parts that form outlet and chamber can be formed by two kinds of materials, promptly limits the hard material of the adjacent surface that forms aquaporin and outlet opening and limits the elastic deformation material who forms the chamber.
Drain valve
In order to play best effect, need establish a check valve in the outlet of chamber, perhaps can play the effect of check valve.Described check valve can make the product that is stored in the chamber only just be distributed by outlet when indoor pressure (moving the volume that causes interior chamber by the elastically deformable wall from initial fexible bias pressure structure reduces) reaches predetermined Minimum Threshold pressure, and whenever closes described outlet to form hermetic seal at other.When the pressure in the chamber is lower than predetermined Minimum Threshold pressure, the closing of valve prevented when release action during to the pressure of the elastically deformable part of main body air by by the outlet back suction in the chamber, when the volume of chamber returns to its initial elasticity voltage biasing structure again along with the elastically deformable wall and increase.
Any suitable check valve assembly that can form hermetic seal can be arranged in this outlet.But described valve is preferably formed by each part of the main body of spray nozzle device.More preferably, valve is formed between each adjacent surface that limits described exit passageway.
In certain embodiments of the present invention, drain valve forms against the another one adjacent surface by a fexible bias pressure in the adjacent surface, thereby closes the part of exit passageway.Thus, when having only the adjacent surface that is enough to make fexible bias pressure when the pressure in the chamber, just open described valve and allow fluid from the chamber, to dispense, thereby form the passage that a fluid in the chamber can flow through away from adjacent surface distortion relatively.In case pressure is lower than when being scheduled to Minimum Threshold pressure, the adjacent surface of fexible bias pressure will turn back to its fexible bias pressure structure and close described passage.
In certain embodiments of the present invention, the whole formation of elastically deformable part of the adjacent surface of fexible bias pressure qualification especially preferred and main body formation chamber.
In certain embodiments, main body is made by rigid plastics fully.Required minimum pressure threshold when the elasticity of fexible bias pressure face (light filling bar of rigid plastics) is not enough to obtain to be used for device and plays the best use of.In these cases, can form the plastics thickening rib that extends through passage, so that required intensity and elasticity to be provided in exit passageway/valve.Alternatively, the hard ribs can be arranged on the top of the part of exit passageway/valve.
In selectable preferred embodiment, form described drain valve by being formed on an elastically deformable element on the adjacent surface, described Crumple element extends through described exit passageway, with closed and sealed described passage.Described parts are installed on the device along an one edge, and another edge (being preferably opposite edges) is freely, and when indoor pressure surpassed predetermined minimum threshold, described free end can move.Described free end forms sealing in abutting connection with the surface of exit passageway when pressure is lower than predetermined minimum threshold.But when pressure surpassed predetermined minimum threshold, the free end of parts moved from the adjacent surface of described groove, forms an opening, and the liquid in the chamber flows to described outlet by described opening.Elastically deformable parts preferred orientation is indoor what form along the length of exit passageway or passage.Adjacent surface free end at parts when pressure is lower than predetermined threshold forms sealing, and preferably tilts gradually or tilt at the free-ended some place of contact component.This just provides a dot encapsulation contact, and enough sealings are provided.Certainly should be understood that and adjacent surface must be arranged to or taper, so that make when indoor pressure is lower than predetermined minimum threshold, the free end of elastically deformable parts contact inclined-plane, but when surpassing predetermined minimum threshold, be out of shape away from it.
Selectively be, described valve can be formed in post or the plug on one the adjacent surface in pedestal or the top, and the adjacent surface that its contact is relative is with closed and sealed described passage.Post or plug will be installed to the deformable zone on pedestal or top, and when indoor pressure surpassed predetermined threshold, post or plug can be out of shape, to form the outlet that a fluid can pass through.
Depend on related application in the indoor required predetermined minimum pressure of drain valve of opening that must reach.Those skilled in the art can recognize how to make the characteristic that surperficial mode (as strengthening ridge by comprising) changes the strain face by selection suitable elastic deformable material or change.
Induction valve
In order only to guarantee by the elastically deformable part of main body is moved into described chamber when compressing described chamber from its initial fexible bias pressure structure, just spray, just need provide a kind of and be arranged on the spray nozzle device place or at the admission valve of its import by outlet.
Can use any suitable induction valve.
Have only the indoor pressure of working as to be lower than predetermined minimum threshold, described induction valve is just opened and is allowed fluid to flow into indoor (have only equally when the strain part that affacts described chamber is released with the pressure of discharge chambe, the volume ability of described chamber is partly recovered its initial fexible bias pressure structure along with strain and increased).In these cases, described induction valve can be flap valve (flapvalve), and it comprises the flapper of the elastically deformable that is positioned at the import top.Described flapper is preferably supporting the elasticity of import bias voltage, and when indoor pressure is lower than the threshold pressure of predetermined minimum, can be out of shape the permission fluid and sucks described chamber by import.But, close all other the time, thereby stop liquid from the chamber, to be back to import.Particularly preferably be, the elastically deformable flapper extends as the integral body of the elastically deformable part that limits the main body that forms described chamber.Also particularly preferably be, pedestal limits and forms import, and the elastically deformable part of main body is formed by top.Therefore top preferably includes the elastically deformable flapper, and it covers the import of leading to described chamber in described indoor extension, thereby forms induction valve.
Selectively be, described flapper can not be to abut against the elasticity of import bias voltage, the substitute is to be arranged on import top, and be configured to have only when the chamber and be compressed, when the pressure in it increases just pressurized abut against import.
Yet, simply adopt the flap valve of against import department to have problems.Particularly, along with the past of time, the elastic limit that forms the material of described flapper will surpass outside its operate as normal limit.The light filling bar that this problem especially can be created in by hard material forms in the embodiment of the invention of described flapper, though it also can be created among the embodiment that uses flexible material with light degree, when the chamber is compressed because this problem will appear in the distortion of flapper and be out of shape when opening valve when described flapper.Therefore, fluid can drain back to the container by import from the chamber.
Because these reasons, described flap valve preferably include many forms that are fit in addition.The spy is in addition, and preferably, import department has the lip of the projection of extending around import, and the flapper of elastically deformable is contiguous to described import to form hermetic seal around import.The setting of lip guarantees to have excellent contact with described flapper.In the very little embodiment of lip, one or more other ribs need be set in each side of import, to guarantee to form suitable seal, also prevent that lip from damaging simultaneously.
Another preferable feature is that flapper has and is formed on its lip-deep projection or stopper.The distance that described projection or stopper extend a weak point enters import, and the adjacent sides edge, with the formed sealing of further reinforcement.
The import of leading to described chamber also preferably is arranged on the position of an indoor rising, thereby liquid flows into the chamber by import, and splash into downwards and keep district or storage area, because import keeps keeping at a certain distance away of district/storage area from the main liquid of described chamber, it is long-time excessively that this just prevents that fluid from resting on the top of induction valve for a long time, thus reduce produce any seepage along with long stop may.
Preferably, second strengthens the apparent surface of flapper or parts contact resilient deformable flapper, to impel itself and the tight adjacency of import.Preferably, second strengthens flapper and partly locates or near the apparent surface of this part place contact resilient deformable flapper, described apparent surface makes the pressure at right angle maximization against the main flapper in hole the apparent surface who covers import.This also helps to keep the integrality that seals.
Locking device
Spray nozzle device also can be provided with locking device, in case the fluid stopping body is distributed by accident.
In these embodiments, locking device will be the intact part of main body, rather than be connected to the separate parts on the main body.For example, locking device can be hinge bar or parts, and its integral body is connected to (for example, pedestal or top) on a part of main body, and it can swing to a position, and described thus bar or parts prevent that drain valve from opening.
Locking device also can comprise rigid cover, and it can be placed on the elastically deformable part of main body, is compressed to stop it.Described lid can be hinged on the spray nozzle device, so that it is folded when needs.Alternatively, described rigid cover can be a top cover slidably, and it can be to lower slider, to compress described chamber during use.Described lid can be twisted so that lock, thereby the accident of anti-locking apparatus triggers.
Air release valve/leak valve
Described device can also comprise reference leakage device, and air can flow by described reference leakage device, with any pressure differential between equalizing reservoir inside and the external environment.In some cases, gas leakage can simply occur in the fit clearance place between distributing nozzle and the container, but this is not preferred, because if seepage may occur when container upset or vibrations.In a preferred embodiment, distributing nozzle also comprises the air leak valve, i.e. a check valve, and it can allow air to flow into container, if but prevent that any fluid from oozing out from container during the container upset.Any suitable one-way valve system all can adopt.But the air leak valve preferably is integrally formed in the body interior of distributor, perhaps especially is preferably formed between two parts of main body of distributor.
More preferably be that the air leak valve is formed between the top and pedestal that limits the chamber that forms dispenser nozzle.
The air leak valve preferably includes the valve member that is provided with in the passage, and this passage is limited by device main body and forms and the liquid source of supply is connected to external environment.More preferably, valve member is subjected to fexible bias pressure to contact the side of described passage, thereby and form sealed engagement with described side and stop any liquid to ooze out from container, valve member also is suitable for strain or qualification forms opening with the sealed engagement place of passage side is removable, when the pressure in the container was lower than at least one minimum threshold amount of ambient pressure, air entered container by the opening of described formation.In case the pressure differential between internal tank and the outside is reduced to when being lower than minimum threshold pressure, valve member turns back to the position of described pathway closure.
Valve member is preferably the form of piston, and it extends in the described passage, and comprises in abutting connection with described passage side to form the wall that stretches out of sealing.The described inner inclination of wall that stretch out towards container.This structure means that the high pressure in the container acts on will make wall keep side adjacency with described passage on the wall of valve member.Therefore, can keep the completeness that seals, thereby stop fluid to ooze out by valve.On the contrary, when the pressure in the container was lower than at least one minimum threshold amount of ambient pressure, described wall entered in the container to allow air away from the side deflection of container, thus balance or reduce pressure differential.
Especially preferably, piston is installed on a deformable pedestal or the flapper, and when moving any residue that accumulates in the air leak valve when the extruding circular top part, described deformable pedestal or flapper can move.In addition, preferably will be movably (for example, strain) element be arranged in the air leak valve because it helps to prevent that described valve from blocking during use.
In certain embodiments of the present invention, over cap also preferably is arranged on the opening of the cloudy pipe on the described device inner surface, makes when container is put upside down or actively shake, and the liquid that stops internal tank is with high pressure or excessive power contact valve member.Described lid allows air and some fluid to pass through, but can stop fluid directly to impact the sealing that the expansion limit by piston forms, thereby prevents that sealing is subjected to the influence of excessive forces.
In another embodiment of the present invention, the passage of air leak valve can be a strain, rather than the male part elastically deformable.The sidewall distortion that this layout can be configured to passage allows air to flow in the container.
Described valve member and passage can be made by identical or different material.For example, they can be made by half flexiplast, and perhaps female element can be made by rigid plastics, and male part can be made by elastic deformable material.
For long term storage some product in container, will produce the problem that bottle interior gas increased along with the time.For the pressure of the increase that discharges this inevitable appearance, just need a relief valve.Above-described air leak valve can be changed realizes this function, and this is to provide one or more strias to realize by the side at described passage.These strias allow gases slowly to ooze out from container gradually, walk around the sealing that the contacts side surfaces by valve member and described passage forms, and still stop or the volume of the liquid that reducing can be oozed out.Preferably, be formed on the outside of the contact point between the side that one or more grooves on the sidewall of described passage are formed on valve member and passage, increase and act on piston and make it outwards during distortion (with respect to container) thereby have only when the pressure of internal tank, just expose it/they.In case described unnecessary gas is overflowed, described piston will turn back to its fexible bias pressure position that can not expose described groove.In this process, liquid just can not run off.
Selectively be, will impel valve member outside, it is moved from described passage, and limit the opening that a described gas can flow through at the gas pressure of internal tank.
Seal
In a preferred embodiment of the invention, comprise at least two parts, sealing device preferably is arranged at least two junctions between the interconnective part, oozes out from spray nozzle device to prevent any fluid.Any appropriate sealing means all can adopt.For example, two parts can weld together, perhaps one of them section construction becomes and another part formation sealed engagement that is clasped, or one of them part has one around its peripheral flange, thereby this flange forms sealing around the upper surface close fit of another part.
Seal preferably includes the positive projection on the adjacent surface that is formed on one of at least two parts, when two parts link together, its with the relative adjacent surface that is formed on another part on the corresponding recesses sealed engagement.
Seal preferably extends around the side of whole chamber and exit passageway, overflows to stop the junction of fluid between two parts of oozing out from any position of indoor and/or exit passageway.
Comprise among the embodiment of an exit passageway that at some described projecting member can be extended and crossed described passage, and form the elastically deformable valve member of drain valve.The part of described protrusion is more thinner usually, realizes its function so that required elasticity to be provided in valve member.
In certain embodiments of the present invention, positive projection can be configured to be clasped with groove, and perhaps alternatively positive projection can be configured to be engaged in the groove to be similar to piston with being engaged in mode repellence in the hole.
Dip-tube
Under the thumping majority situation, dip-tube can form with spray nozzle device is whole, and perhaps alternatively, the main body of spray nozzle device can comprise recess, and independently dip-tube can be installed in the described recess.Described dip-tube can make fluid draw from the container deep inside during use.
Selectively be, need to adopt some container, small containers particularly, as balsam bottle, scent flask and nose spray bottle, and omit dip-tube, because device itself may extend in the container, during use product is drawn in the nozzle, perhaps container can overturn and be beneficial to distributor filling liquid.Selectively be, device also comprises the fluid compartment that forms as the integral part of device, can be from described fluid compartment directly with the import of liquid drawing to nozzle, and do not need dip-tube.
The chamber
The chamber of spray nozzle device can be any form, should be realized that certainly the size and dimension of dome is chosen to be fit to related concrete device and application.Similarly, all indoor when dome is compressed fluids can be discharged, and perhaps alternatively, indoor only a part of liquid can distribute, and this depends on related application equally.
In some preferred embodiment of the present invention, described chamber is formed by the strain area definition of the main body of general dome shape.Dome-shaped zone is preferably formed on the upper surface of main body, so that operator's easy operating when using nozzle.Adopt one of them problem of dome-shaped chamber to be, when it is compressed by the operator, the dead angle that indoor existence is certain, for some application, the dead angle is preferably reduced to minimum or in fact can be ignored.In order to obtain this specific character, have been found that and adopt the flat dome or the chamber of other shape, thereby the elastically deformable wall that can push described chamber makes its relative wall that contacts described chamber, thereby discharge all substances in it, this is preferred.Because this reason, the dome of preferred flat especially is because it has reduced for discharge chambe and has promoted to store the discharge of liquid within it and the degree of inwardly pushing dome.It has also reduced to use the amount that need push the filling of described chamber for the first time for preparing described chamber in advance.
In some cases, the elastically deformable of main body part can not have sufficient elasticity, with the initial fexible bias pressure structure after keeping it to be out of shape.This can be following situation, and promptly fluid has high viscosity, therefore has opposing to suck the tendency of described chamber by import.In these cases, by being set, one or more elastically deformable posts provide extra elasticity in orientation room, described post bending when the chamber is compressed, and when removing the pressure that is acted on, impel the deformable segment of main body to get back to its initial fexible bias pressure structure.Selectively be that the rib that thickens of one or more plastics can extend towards the middle of this part from the edge in elastically deformable district.These ribs play the effect of leaf spring and increase the elasticity in elastically deformable district, and when pressure acted on the elastically deformable part of main body, these ribs were compressed, and these ribs impel this part to get back to its initial fexible bias pressure structure when removing the pressure that is acted on.
It is indoor that selection in addition is that the elastic device of spring or other form is arranged on.As mentioned above, spring will be compressed when wall is out of shape, and spring impels the deformable segment of main body to get back to its initial fexible bias pressure structure when removing the pressure that is acted on, and by like this, impels the chamber of being compressed to turn back to its initial " non-pressure texture ".
Two or more chambers
Spray nozzle device of the present invention can comprise two or more independently inner rooms.
Each independent chamber can be by the homogeneous turbulence body source never of import independently, as the independent compartment that is full of liquid in same containers with liquid inlet nozzle device.
Alternatively, one or more other chambers can not comprise import.Replace, the reservoir of one second kind of fluid can be stored in the chamber itself, and other chamber or its outlet only allow second kind of liquid of scheduled volume to distribute can be configured to move the time at every turn.
Select as another kind, one or more chambers of other chamber can suck the outside of air from spray nozzle device.No matter the liquid that from the separate compartment of internal tank inhaled air or other kind are contained in other one or more chambers whether, the content in two or more chambers can both be ejected by outlet simultaneously by compressing these two chambers together.Content in the respective compartments mixes in described outlet then, and this mixing occurs in when spray nozzle device sprays, before spraying or after spraying.Should be realized that the size of the relative volume that changes each separate chambers and/or outlet can be used to influence the relative scale of each component in the final mixture of being discharged by outlet.In addition, exit passageway can be divided into two or more independently passages, and each passage is from independently extending out the chamber, each independently passage can liquid be conveyed into aforesaid spray nozzle device passage in mixing place before liquid is injected.
When other chamber that existence is used for that air discharges, should be realized that, when the discharge of a denier air is finished, remove the pressure that is acted on, thereby the distortion that makes the chamber turns back to its initial expansion structure, just need be with the air replenish to discharge in the more air suction chamber.This can realize (that is, not providing airtight drain valve for this other chamber) by air is sucked back by outlet, perhaps more preferably, air is sucked by the inlet hole that limits in the main body that forms described chamber.In the latter case, inlet hole preferably is provided with a check valve that is similar to above-mentioned induction valve.This valve only allows in the air suction chamber, and stops air to be discharged by the hole when the described chamber of compression.
Under the thumping majority situation, the liquid in air and the container need be sprayed jointly with roughly the same pressure.This compression that will need air chamber is greater than the chamber of containing fluid/liquid (for example, depend on related application and be not all 3-200 doubly).This can obtain by locating described each chamber, makes that the compression of the chamber of interior dress air preferentially produces, thereby air is sprayed under identical or roughly the same pressure with liquid when effect pressure.For example, the back of the chamber of dress liquid in the chamber of interior dress air can be positioned at, thus when effect pressure, air chamber at first is compressed to two compressed together stages of chamber.
As a kind of selection, spray nozzle device also can be configured to, and air pressure can be higher or lower than fluid pressure, and this situation is very favourable for some application.
Described each chamber can be arranged side by side or chamber can be arranged on the top of another chamber.In a preferred embodiment, contain air in one of them other chamber, this other air chamber makes the compression of air chamber make the elastically deformable of main body partly be out of shape the also chamber of constricting nozzle device with respect to the location, chamber of spray nozzle device.
The fluid that exists in each chamber preferably sprays simultaneously.But, should be appreciated that its fluid can be sprayed in a chamber before or after another chamber in some applications,
In other embodiments, air in the container and liquid may reside in the single chamber, rather than how independently in the chamber.In these cases, fluid and air spray jointly, and mixed when it flows through outlet.For example, outlet comprises expanding chamber, promptly is arranged in the widened chamber of exit passageway, and the material that sprays from the chamber can be divided into each individual branches of passage, and enters expanding chamber to promote mixing in different positions.
