The present invention relates in spray nozzle device or associated improvement, but not uniquely relate at the moving spray nozzle device of pump and make in the method for this device or associated improvement.

Background of invention

The moving spray nozzle device of pump is commonly used to provide the device that can distribute fluid from vessels not under pressure.

But it is very complicated and generally include many building blocks (10 to 14 independent building blocks are arranged usually) that the moving spray nozzle device of traditional pump trends towards structure.So therefore owing to form the needed quantity of material of these independent building blocks and related these device manufacturing cost costlinesses of assembling process.

Therefore, expect to have the moving spray nozzle device of a kind of like this pump, it has following characteristics:

(i) simple in structure;

(ii) used building block still less; And

(iii) actuate easily.

Summary of the invention

The present invention is directed at least some problems relevant and provided a solution with the moving spray nozzle device of traditional pump, the present invention provides a kind of like this pump to move (pump-action) spray nozzle device in first aspect, the fluid that is used for will being stored in the fluid source by described nozzle during use distributes, described nozzle has a main body, it is limited with: one first chamber, this chamber has an inlet and an outlet, fluid can be drawn in the described chamber by this inlet, fluid in the chamber can be discharged from nozzle by this outlet, described inlet comprises an inlet valve, only be used for allowing fluid to flow in the chamber when pressure in chamber drops to than the low at least one minimum threshold amount of the pressure in fluid source, and described outlet comprises an outlet valve, and it only constitutes and to allow fluid to flow out from chamber when therein pressure surpasses at least one minimum threshold amount of the external pressure in exit and discharge from nozzle; And one second chamber, it comprises an at least one outlet and an outlet valve, at least a portion main body that wherein defines described first and second chambers constitutes:

(i) applying in response to pressure from expansion of initial elasticity bias voltage form strain to one or deformation form, the volume of described chamber that described that part of main part limitation is arranged thus is along with described that part of main body is deformed into described expansion or deformation form reduces from described initial configuration, and described volume reduces to make the pressure in described chamber to increase and by outlet fluid discharged; And

(ii) turn back to its initial elasticity bias voltage form removing during applied pressure subsequently, make the volume of chamber increase thus and pressure is wherein descended, thereby be drawn in first chamber by inlet valve to major general's more fluid;

It is characterized in that, described spray nozzle device also comprises an actuator member, it extends at least a portion of described that part of main body and so constitutes, and makes actuator member engage described that part of main body and makes it and begin distortion to compress described first and second chambers from its initial bias voltage form thereby exert pressure to described actuator.

The many shortcomings of the present invention by providing a kind of like this spray nozzle device to solve the moving spray nozzle device of known pump, it is very simple and generally include no more than six independent building blocks, the spray nozzle device that they are assembled together and assemble with formation that this installs its structure.In preferred embodiments, this device will comprise no more than three building blocks, perhaps two independent building blocks more preferably, and perhaps even more preferably this device is formed by single integrally formed parts.For " separately building block ", we refer to these parts and connect by any way, promptly they do not form as one mutually (but each independent building block comprise with or a plurality of global facility or part).The key that reduces building block quantity is to form necessary parts in this device main body.For example, chamber, inlet, inlet valve, outlet and outlet valve can all be formed by this main body, have reduced thus will comprise independent building block thereby cause building block and the needs of assembly cost increase.

Spray nozzle device of the present invention can also have more by setting, and an actuator member of simple structure solves and moves the relevant problem of spray nozzle device at the pump disclosed in EP0442858A2, US3829689 and the EP0649684.This actuator member provides a kind of like this device that makes things convenient for, and can actuate from first and second chambers by it and distribute fluid.

In addition, spray nozzle device of the present invention is provided with such device in addition, can distribute two kinds of fluids by it from spray nozzle device.This spray nozzle device can comprise third and fourth further chambers that is used for special-purpose.Each chamber can include fluid, and perhaps one or more in these further chambers can include air or another kind of gaseous fluid.

Actuator member can be an arm, and operating personnel push this arm so that described that part of bulk deformation.

But in some preferred embodiment of the present invention, actuator member is a block, and it extends on the elastically deformable of main body part and be formed with and can be pushed so that make described that part of bulk deformation and actuate the surface that distributes fluid from the chamber of this device thus by operating personnel.Preferably, the surface that is formed by described block is a continuous surface.Preferably, described actuator surface is arranged on the upper surface of this device.

Actuator member can constitute in bending when its outer surface is exerted pressure or otherwise be out of shape so that the feasible elastically deformable part that defines the main body of described chamber can begin distortion from its fexible bias pressure form.But preferably this actuator member be rigidity or rigidity basically.

In some preferred embodiment of the present invention, actuator member so constitutes, thereby it can slide with respect to the main body of spray nozzle device when exerting pressure, and makes the elastically deformable part of main body can selectively engage and break away from its fexible bias pressure position in response to exerting pressure to actuator thus.In other preferred embodiment of the present invention, handle is pivotally mounted on this device main body.

In other preferred embodiment of the present invention, actuator member is a trigger-actuated device.Preferably, comprise can be by the trigger handle of operating personnel pulling and be configured to engage described that part of main body when the described trigger handle of pulling and make it the bonding part that begins to be out of shape from its fexible bias pressure position for this trigger-actuated device.The trigger-actuated device so uses, thereby when operating personnel spurred the trigger device, a part of bonding part was engaging the elastically deformable part of main body and making it strain, thus compression chamber and make the fluid in chamber discharge by the outlet of this device.

Preferably, the handle of trigger-actuated device is according to extending below outlet with the similar mode of traditional trigger spray nozzle device, promptly make operating personnel can catch this spray nozzle device, outlet is orientated along desired direction, and comes distributing fluids by base pulling trigger-actuated device towards spray nozzle device.

Preferably, this trigger-actuated device is pivotally mounted on the main body of spray nozzle device, thereby pulling trigger handle makes the bonding part pivot and partly exerts pressure to the elastically deformable of spray nozzle device main body.When unclamping the actuator handle, the elasticity of the elastically deformable of spray nozzle device main body part pushes back the trigger device state of its initial " not spurred ".

Pivotally connectedly can be formed on arbitrarily suitable position.For example, pivot can be located at the edge (for example, leading edge or trailing edge) of upper surface and locate, more preferably, and pivotally connected can for example being on the upper surface in the position at separating device edge near the upper surface middle part place of this device or its.Pivotally connected being positioned at when spurring the trigger device that has been found that this back provides more naturally or the sensation of " being familiar with " for operating personnel.

The trigger-actuated device can also be partly or entirely goes out with flexiplast is over-molded, thereby more soft contact surface is provided, thus increased grasping it the time operating personnel comfort level.If requirement also can be applied to back hinge to strengthen it with flexiplast is over-molded.

For the elastically deformable of giving chamber partly provides necessary elasticity, it can be thickeied and/or be included in the ribs that extends across the elastically deformable main part.

Actuator member can be an independent building block, and it can be connected with spray nozzle device.

But preferably, actuator and main body form as one.More preferably, actuator is connected with main body by collapsible Connection Element, and constitutes around Connection Element and pivot so that described that part of main body can be out of shape.

Second chamber

Second chamber also can comprise an inlet, can will the fluid suction of independent chamber of the container of this device for example be installed from second fluid source on it by it.In these cases, second chamber preferably includes the inlet with inlet valve.

Optionally, second chamber does not comprise inlet at all.What replace is, the container of second fluid can be left in second chamber, and this fluid can singly be actuated middle distribution at one, and perhaps the outlet of second chamber can constitute second fluid that only allows to distribute scheduled volume along with actuate at every turn.

As another possibility, the additive fluid that is included in second chamber can be gas or admixture of gas air for example.In the situation of back, it is desirable in special-purpose the common air of discharging especially because the fluid of viscosity more for example hair setting water, cream, scrape under the situation of foam recklessly etc. and can be for example to come in the broken situation liquid droplets that distributes from this device or the performance that changes institute's ejecting product at injection nozzle apparatus by producing mixture that foam utilize air stream and one other fluid.

There is second chamber therein or is used for discharging the embodiment of the further chambers of air, in case discharging air finishes and removes institute's applied pressure and make the elastically deformable of chamber partly be out of shape thus to get back to its initial elasticity biased position, then need more air is drawn in this chamber to replenish the air of being discharged.This can go into the air suck-back (that is, by outlet valve is become two-way valve) or more preferably by utilizing independent air inlet to realize from external environment condition suction air by utilizing outlet.In the situation of back, air inlet preferably is provided with and the similar one-way valve of above-mentioned inlet valve.This valve will only allow air to be drawn in the chamber, and will prevent that when chamber is compressed air is discharged from by the hole.

In most of situation, preferably eject second fluid jointly from second chamber with the pressure substantially the same with the air that ejects from first chamber.If second fluid is an air, then this will be usually need be than fluid/contain more times compressed air chamber of liquid chamber (for example, many 5 to 200 times, this depends on related purposes).This can realize by these chambers so are set, thereby when exerting pressure, the compression that contains the chamber of air preferentially occurs, and makes air can go out with identical or essentially identical pressure injection with liquid thus.For example, the chamber that contains air can be arranged on the chamber back of containing liquid, thereby when exerting pressure, the stage when air chamber at first is compressed to and arrives two chambers and compressed together.

Optionally, this spray nozzle device can also use according to a kind of like this mode, thereby is higher or lower than fluid pressure from the pressure that second chamber discharges fluid, and this is favourable for some applications.

When in spray nozzle device, having two or more independent chamber, allow the outlet valve of each chamber open the problem of having simultaneously.For this reason, preferably, this device is constructed such that partly to exert pressure to the elastically deformable of main body and can helps outlet valve at predetermined point or time deformation/open.

Preferably, air chamber is arranged between actuator member and the apparatus main body, makes air chamber be compressed thereby push or spur actuator (under the situation of trigger-actuated device) towards main body.

In optional embodiment, can be in single chamber rather than a plurality of independent chamber from the air and the fluid of container.In these situations, fluid and air are ejected jointly and can be mixed its mobile passing when exporting.For example, comprise that in outlet an expansion chamber for example is arranged under the situation of widening chamber in the exit passageway, the independent branch of the content division admission passage that ejects from chamber and enter expansion chamber in different positions and mix promoting.

No matter be that further chambers or chamber comprise air or extract some other fluids out from the independent chamber in container, can be by compressing simultaneously the content that two chambers come to eject simultaneously by outlet identical or separately simultaneously these two or more chambers together.

Therefore, in certain embodiments, each all comprises an exit passageway that extends to independent outlet opening from each corresponding chambers the outlet of described first and second chambers.In optional embodiment of the present invention, the outlet of described first and second chambers comprises the exit passageway that extends to single outlet opening from each corresponding chambers, these passages so merge, thereby the fluid that distributes from each chamber during use mixed in exit passageway before distributing by described outlet opening.

It should be understood that can be by changing independent chamber relative volume and/or the size of outlet influence the relative scale that is in the constituent in the final mixture of discharging by outlet.In addition, exit passageway can be divided into two or more individual passage, and each passage extends from an independent chamber, and every individual passage can equally flow to nozzle passage with fluid as mentioned above, before spraying it is mixed there.

These chambers can be arranged side by side or a chamber can be positioned on the top of another chamber.A further chambers includes in the preferred embodiment of air therein, and the additive air chamber so is provided with respect to the chamber of spray nozzle device, thereby the compression of air chamber makes the elastically deformable of main body partly be out of shape and the chamber of constricting nozzle device.

This device can also comprise the 3rd and/or the 4th chamber.For example, two chambers can dispense liquid, and the 3rd chamber can air distribution, perhaps all chambers dispense liquid all.

The formation of spraying

In certain embodiments of the invention, the outlet of spray nozzle device is used for producing the spraying of the fluid that ejects from the chamber of spray nozzle device.The outlet of spray nozzle device is used for utilizing the device of any appropriate known in the art to carry out this function.For example, the outlet opening of outlet can be the micropore that so constitutes, thereby makes flow through under the pressure fluid in this hole split into many drops.But in these embodiments, preferably outlet comprises an outlet opening and the exit passageway that chamber is connected with outlet opening.Outlet valve preferably is arranged in the exit passageway.Especially preferredly be, exit passageway comprises that one or more interior spray change parts, and they are used for reducing during use the size of the drop that the outlet opening by spray nozzle device distributes.The example that can be in the interior spray change parts in the exit passageway comprises one or more expansion chamber, one or more swirl chamber, one or more interior spray hole (being used for producing the fluid spray that flows through in exit passageway) and one or more Wen's chamber.The known one or more sizes that can influence the liquid droplets that between the operating period of this device, produces that comprise above-mentioned parts.It is believed that these parts help to make the drop atomizing that is produced alone or in combination.It is known in the art acting on aspect the spray characteristics that is produced that these sprayings change parts and they, and for example disclosed in international patent publications WO 01/89958, and the full content of this patent here is cited as a reference.It should be understood that the outlet valve and the outlet opening that are positioned at the exit passageway upstream are set has guaranteed that fluid enters exit passageway under the power effect that is enough to make liquid split into drop and formation spraying.

In certain embodiments of the invention, exit passageway and outlet opening can be taked the form of independent unit or insert, and it can be connected to form the outlet of this spray nozzle device with the outlet of chamber.This unit or insert also can be connected with this device main body by hinge, thereby enable arbitrarily to swing to in the desired location of using and be swung away from this position when not needing it.

In comprising the embodiment of air chamber, preferably, air mixes with the liquid that distributes from other chamber in spraying changes parts.Usually spraying change parts will be an expansion chamber or swirl chamber.

In optional embodiment of the present invention, the liquid that is arranged in chamber can distribute according to the liquid that does not split into drop is streamed.The example of these liquid that distribute according to this form comprises soap, shampoo, milk wet goods.

Optionally, the fluid that is distributed can be gas or admixture of gas air for example.

Internal chamber

The chamber of spray nozzle device can be arbitrary form, and it being understood that certainly the size and dimension of these chambers will be selected as satisfying related specific device and purposes.Equally, all fluids in these chambers can be discharged when these chambers are compressed, and perhaps optionally can only distribute the part of the fluid in these chambers according to related purposes.

In some preferred embodiment of the present invention, these chambers can be by the area limiting that is substantially arch of the elastically deformable of this main body.Preferably, these arch area so are formed on the upper surface of main body, these regional strains thereby operating personnel can exert pressure.

A problem of arch chamber is, has a certain amount of dead band when operating personnel compress it in this chamber, and for some purposes, this dead band is minimized or in fact can ignore.In order to realize this characteristic, the chamber that has been found that the vault of flattening or other shape is normally preferred, can so push the elastically deformable part of chamber thus, thereby it and the relative wall contact that defines this chamber are discharged all the elements thing therein thus.For this reason, the vault of flattening is particularly preferred, because it has reduced inwardly to push the degree of vault so that compression chamber and startup memory allocated fluid therein.It has also reduced makes this chamber prepare to use for the first time required compression number.

In some cases, the elastically deformable part that defines the main body of described chamber may not have enough elasticity to keep its original fexible bias pressure state after distortion.This may be such a case, and wherein fluid has high viscosity and therefore trends towards resisting being drawn in the chamber by inlet.In these situations, can be by one or more elastically deformable pillars be arranged on the elasticity that provides extra in the chamber, these pillars are crooked and the crushed element of main body is pushed back its original fexible bias pressure form removing during applied pressure when chamber is compressed.Optionally, one or more thickening plastics rib can extend in the middle of this part from the edge in elastically deformable zone.These ribs are by having increased the elasticity in elastically deformable zone as a slice spring effectively, and this sheet spring is got back to its initial elasticity bias state in compression and this part when the elastically deformable of main body is partly exerted pressure when removing institute's applied pressure.

Another possibility is, is provided with the elastomeric element of a spring or another kind of form in chamber.As top, this spring will compress when wall is out of shape, and the crushed element that will push main body removing during applied pressure to be making it turning back to its original fexible bias pressure state, and like this its original " state that is not compressed " got back in the chamber pushing of compression.

The main body of spray nozzle device

Chamber by main part limitation can be limited between two or more interconnecting parts of main body.Particularly preferably, the chamber of spray nozzle device is limited between two interconnecting parts, and these parts can be for being assembled together with the building block of the independent shaping that limits this chamber.Perhaps more preferably, these two parts are integrally formed as single building block mutually.In the situation of back, preferably, these two parts link together by the hinged or foldable connection element, and this makes that two parts can be molded together in identical mould, and they are in contact with one another to limit chamber.

Outlet therein comprises outlet valve, outlet opening and chamber is connected in the preferred embodiment of the invention of the exit passageway on the outlet opening that further preferably, at least two interconnecting parts that define these chambers also define at least a portion exit passageway.Most preferably, two interconnecting parts form outlet valve and define whole exit passageway and outlet opening between them.

Exit passageway preferably is limited between one the abutment surface and another the relative abutment surface in the described part in the described part.One or more one or more formation groove and/or grooves thereon that comprise in these abutment surfaces, they define exit passageway when these abutment surfaces contact.More preferably, each described abutment surface comprises formation groove and/or groove thereon, and they are aimed at when abutment surface contacts to form exit passageway.These grooves and/or groove preferably extend to the opposite edges of abutment surface from chamber, the place, end at exit passageway forms oral pore when abutment surface contacts there.As shown in the international patent publications No.WO 01/89958 with described the same, exist one or more sprayings to change in the preferred embodiment of parts therein in exit passageway, these parts can form by the groove that is formed on the abutment surface or other shaped portion are aimed at.

Two parts of main body can be permanently fixed together by for example ultrasonic bonding or hot weld.If substrate and top are molded or weld together, preferably they are made by compatible material.

Optionally, these two parts can constitute mutually closely/be assembled together inimically to form nozzle (for example, connecting by snap fit is set) in without any the situation of welding.For example the edge of a part can constitute in the binding groove that fits into another part to form spray nozzle device.

As another possibility, compatible plastic material can be molded on the coupling part of two parts to fasten them together.This can by in mould simultaneously molded two parts, in mould, they are joined together to form spray nozzle device and come together to realize this round their molded suitable plastic materials to hold them in then.

In certain embodiments, these two parts can keep removably connecting mutually, thereby they can separate during use with can cleaning chamber and/or outlet.

Most preferably, two parts of main body that define the spray nozzle device of chamber are a bottom and a top.The bottom is used for preferably that for example screw thread or snap fit are linked and packed on the opening of container by suitable means.In addition, except formation defined a part of main body of chamber, the bottom also preferably defined a part of exit passageway that enters the mouth and extend to outlet opening from the chamber chamber in preferred embodiments.

Top is used for being assemblied on the bottom, thereby defines chamber between them, and has formed outlet valve, exit passageway and/or outlet opening in preferred embodiments. and in some preferred embodiment of the present invention, bottom and bottom also are formed with outlet opening.Further preferably, the elastically deformable part of the main body that defines chamber is formed at top.

Preferably, top comprises the first of main body, and the bottom comprises the second portion of the main body that limits above.

Material

The main body of this spray nozzle device can be made by the material of any appropriate.

Main body comprises that these two parts can be made from the same material or a different material in two certain embodiments of the present invention that are assembled together with the interconnecting parts that forms chamber therein.For example, one of them part can by flexibility/deformable material for example elastically deformable plastics or elastomeric material make, and another part can by rigid material for example rigidity plastics make.These embodiments are preferred for some purposes, eject and are out of shape being in fluid in these chambers to actuate because flexibility/deformable material has formed the second portion of the main body that limits these chambers and can be have easily pushed the actuator surface by operating personnel.Flexible material can also provide soft sense of touch for operating personnel.Can be by the molded separately spray nozzle device or use dual shot molded technology molded these two parts in equal dies that assemble of then they being joined together to form of two parts be realized these embodiments.In the situation of back, two parts can be molded into then simultaneously and be assembled together in mould, perhaps can at first be molded into a part with first material, second parts of being made by second material can be molded directly in the first then.

Optionally, these two parts can be made by rigidity or flexible material.Rigidity and flexible material can be for being used for forming the suitable material of spray nozzle device arbitrarily.For example, it can by metal material for example aluminium foil or flexible material for example rubber form.But preferably, this device main body is all formed by rigid plastic material, though, if the first of main body is the same as requested, can adopt flexible plastic-type material.

Preferably, the first of main body is formed by rigid material.Most preferably, the moving spray nozzle device (being main body and actuator) of entire pump is formed by single rigid plastic material of planting.

Term " rigid plastic material " has a plastic material that is molded as desired form then has high rigidity and intensity in case be used to refer to generation here, but also can make it in some parts flexibility or elastically deformable more by the thickness that reduces these plastics.The parts of plastics that thinning therefore can be set defines chamber with formation and is configured at least a portion main body of strain.

Term " flexiplast " here be used to refer to for inherent flexibility/elastically deformable in case make at least a portion main body can resilient bias so that compress the plastic material of this chamber.The flexible degree of plastics can depend on the thickness of these plastics in any given area or place.This " flexiplast " material for example is used to make shampoo bottle or hair jelly container.In making spray nozzle device of the present invention, the part main body can be formed by thicker parts of plastics thinks that this structure provides required rigidity, and other parts can be made of thinner parts of plastics so that necessary deformable characteristic to be provided.In case of necessity, if in some zone, need extra rigidity, the framework of the more thickness portion that is commonly called ribs can be set then.

Use and singly to plant the advantage that material forms spray nozzle device be that whole spray nozzle device can be molded in the single mold operation in single mould, as following further as described in.

Thereby two parts form as one and can be rocked in the preferred embodiment that contacts the spray nozzle device that assembles with formation with the bottom by collapsible Connection Element or the crosslinked top that interconnects especially therein, form spray nozzle device and needing to have avoided a plurality of independent parts of assembling with single material of planting.In addition, provide the possibility that two parts is welded together (for example by hot weld or ultrasonic bonding) with single material formation spray nozzle device of planting, if perhaps plastic material is a rigid plastic material, then can between top and bottom, forms snap fit and connect.The selection of back also makes bottom and top regularly to take apart so that clean.

For most of purposes, this spray nozzle device must be made by rigid material and think that the actuator surface provides required intensity, and makes that these two parts can snap fit or weld together.In these cases, the deformable segment of main body often only is out of shape when having applied particular minimum threshold pressure, and this produces more pressing as the conventional pump moving spray nozzle device relevant with the ON/OFF action.Yet, in some purposes, preferably adopt flexible material.

The second portion that constitutes the main body of strain can be relatively thin rigid plastic material part, it when exerting pressure strain to compress this chamber and when removing institute's applied pressure, to return to its initial elasticity bias state subsequently.

But in most of the cases, preferably, though defining the abutment surface of the exit passageway of outlet is formed by rigid plastic material. can use flexibility/deformable material for this reason, but they are more not preferred usually, because spraying change parts usually all must be by the rigid material precise forming arbitrarily.Therefore, in some embodiments of the present invention, one that defines outlet and two parts of chamber can be formed by two kinds of materials, i.e. formation define exit passageway and outlet opening abutment surface rigid material and define the deformable material of chamber.

Outlet valve

In order optimally to work, the outlet of at least the first chamber must be provided with an one-way valve or be applicable to as one-way valve.Preferably, two chambers comprise single-pass outlet valves, but in some cases, the outlet valve that equally is used for second chamber as mentioned above can be two-way valve (if for example second chamber is an air chamber, being used for allowing air is pumped in second chamber).

One-way valve is set makes to have only and when in this chamber, having realized predetermined minimum threshold pressure, could distribute the fluid (owing to the elastically deformable by main body partly leaves reducing on the caused volume in internal chamber of its initial elasticity bias state) that is stored in each chamber, and all close these outlets At All Other Times at all by outlet.When coming back to its original fexible bias pressure state along with the elastically deformable wall, the A Tiji that shut off valve has prevented pressure on having removed the elastically deformable part that is applied to main body and this chamber when the pressure in these chambers is lower than predetermined minimum threshold air is sucked back in the chamber by outlet.

Can use the one-way valve assembly that can form gas-tight seal of any appropriate.But preferably, these valves are formed by the part of the main body of spray nozzle device.Most preferably, these valves are formed between the abutment surface that defines exit passageway.

In certain embodiments of the invention, by making one of them the abutment surface resilient abutment that defines exit passageway on the phase time abutment surface, form these outlet valves with a part of length of closing exit passageway.In this, these valves will be just be enough to make that the abutment surface distortion that is subjected to fexible bias pressure leaves that the relative resilient surface forms thus that the fluid that can allow from each chamber therefrom flows through opens to allow fluid to distribute when opening passage when the pressure in each chamber from chamber.Be lower than predetermined minimum threshold in case pressure drops to, the surface that then is subjected to fexible bias pressure will turn back to its fexible bias pressure state and close this passage.

In certain embodiments of the invention, particularly preferably, the fexible bias pressure abutment surface partly forms as one with the elastically deformable that defines the main body of chamber.

In the whole embodiment of being made by rigid plastic material of main body, the elastic force that is provided by fexible bias pressure surface (can be thin rigidity plastics part) is not enough to realize being used for the optimum required minimum pressure threshold of working of this device therein.In these situations, can be formed on the thickening plastics rib that extends on the whole passage in exit passageway/valve so that necessary strength and elastic force to be provided.Optionally, the rigidity ribs can be set above section port passage/valve.

In optional preferred embodiment, can be formed for closing one or more in these outlet valves with seal channel by the elastically deformable member on one of them described abutment surface of being formed on that on whole exit passageway, extends.This member is installed on this device along an one edge, and its another edge (being preferably opposite edges) freedom, and the pressure that free end constitutes in chamber surpasses the predetermined minimum threshold hour offset.This free end surface in connection with exit passageway when pressure is lower than predetermined minimum threshold seals to form with it.But when pressure surpassed predetermined minimum threshold, the free end of this member was used for allowing fluid the chamber can flow to the opening of outlet by its from the abutment surface skew of passage with formation.Preferably, this elastically deformable member is arranged in the chamber that forms along the length of exit passageway.Most preferably, be taper or inclination being lower than under the pressure of minimum threshold the abutment surface that free end with member forms sealing at free end position contacting place with this member.This provides the dot encapsulation contact, and more effective sealing is provided.Certainly it being understood that the cone of abutment surface or inclined-plane must so arrange, thereby contact with the inclined-plane when pressure of the free end of elastically deformable member in chamber is lower than predetermined minimum threshold, still above predetermined minimum threshold the time, separate with it.

Optionally, this valve can for be formed on one the abutment surface in bottom or the top and with the contact of relative abutment surface to close a pillar or the plug with seal channel.This pillar or plug will be installed on the bottom or the changeability zone on top, thereby when the pressure in chamber surpasses predetermined threshold, thereby this pillar or plug can be out of shape to form and can allow fluid flow through the opening of outlet by it.

The predetermined minimum pressure that must realize in chamber in order to open outlet valve will depend on related purposes.Those of ordinary skill in the art will recognize that how by for example selecting suitable deformable material or change to constitute the characteristic that this surperficial mode (for example strengthening spine by comprising) changes the elastically deformable surface.

Inlet valve

Just move forward into when coming compression chamber the chamber from its initial elasticity bias state in order to ensure fluid and to eject by outlet in the elastically deformable part by making main body, must the porch of spray nozzle device or among a single-pass inlet valve is set.

Can use suitable inlet valve arbitrarily.

This inlet valve can be used for the pressure in chamber just and drop to when being lower than predetermined minimum threshold (the same with the situation when having removed the elastically deformable that is applied to chamber and partly go up volume with the pressure of compression chamber and this chamber and partly recover its initial elasticity bias state along with elastically deformable) and just open and allow fluid to flow in the chamber.In these cases, inlet valve can be a clack valve, and it is made of the elastically deformable flap that is arranged on above the inlet opening.This flap preferred elastomeric is biased on the inlet opening and is applicable to that the pressure in chamber drops to distortion when being lower than predetermined minimum threshold so that permission is drawn into fluid in the chamber by inlet.But, at all other constantly, this inlet will be closed, and prevent that thus fluid is from the chamber inlet port that refluxes.Particularly preferably, this elastically deformable flap forms the whole extension of the elastically deformable part of the main body that defines chamber.Also particularly preferably be, the elastically deformable part that inlet and main body have been formed on the bottom is formed by top.It is therefore preferable that top is included in extension in the described chamber so that be covered with the inlet opening that leads to chamber and the elastically deformable flap that forms inlet valve.

Optionally, flap not fexible bias pressure and is arranged on above the inlet opening and so constitutes on the inlet opening, thereby only is compressed and wherein pressure just is resisted against on the inlet when increasing at chamber.

But the clack valve of fexible bias pressure on the inlet opening simply is set can go wrong.Specifically, as time goes by, the elastic limit of materials that forms this flap can surpass, and this makes it and can not correctly work.This problem especially can be occurred by embodiment of the present invention that thin rigid material partly forms for flap wherein, but it also also occurs for flexible material but degree is littler, and can be owing to cause appearance when chamber is compressed and in flap distortion flap distortion when opening valve.Therefore, fluid can leak from chamber by inlet and get back to the container.

Owing to these reasons, preferably, clack valve comprises many variations.Specifically, preferably, inlet has the protruding lip that extends round the ingate, thereby this elastically deformable flap is resisted against on this lip with round going into the interruption-forming tight seal.Be provided with that lip has been guaranteed and flap between realize excellent contact.In the embodiment that lip is very little, must one or more additional supporting ribs be set therein, to guarantee forming correct sealing and to prevent that lip from damaging at the either side place of inlet opening.

In the following explanation of these accompanying drawings, in appropriate circumstances, identical reference number is used for representing identical or corresponding part in different accompanying drawings.

The specific embodiment

Fig. 1 demonstrates first embodiment of spray nozzle device of the present invention.Being used for this device of form distributing fluids with spraying comprises by the i.e. main body 100 that forms of a bottom 101 and a top 102 of two parts.Bottom 101 and top 102 interconnect by collapsible Connection Element 103.On bottom 101, also be connected with a trigger-actuated device 400 by another collapsible Connection Element 103a.

Bottom 101 is used for being assemblied on the container (not shown) to allow will be stored in during use fluid in the described container and is pumped in the described device and from described device and distributes.

Bottom 101, top 102, trigger-actuated device 400 and

Connection Element

103 and 103a form as one in the single mold operation with a kind of rigid plastic material in the structure shown in Fig. 1.Therefore, whole device is formed by single integrally formed part.

In order to form the spray nozzle device that assembles, be assemblied on the upper surface of bottom 101 to form this device main body with top 102 upset and with it around Connection Element 103, and the trigger-actuated device will overturn around Connection Element 103a then, thereby extend on the device main body upper surface bonding part 402, and handle 401 extension that faces down before device.

When bottom 101 and top 102 are assembled together when forming this device main body, the adjacent part/surperficial 101a of the part 102a of the lower surface on top 102 upper surface of 101 in connection with the bottom.In addition, the recessed portion 101b of the upper surface of

bottom

101 and 101c aim at corresponding recessed

portion

102b and 102c in the lower surface that is formed on top 102 respectively, thereby form two independent internal chamber.

Each chamber comprises ingate 104a and the 104b that is formed in the bottom.Each ingate is arranged in corresponding grooves 105a and the 105b as shown in fig. 1.In the time of on top 102 being assemblied in bottom 101, the flap 106a and the 106b of elastically deformable are contained in respectively in these grooves 105a and the

105b.Flap

106a and 106b respectively fexible bias pressure on the opening of ingate 104a and 104b to form inlet valve.Therefore, thus fluid just the pressure in the ingate surpass opening that the described flap of pressure in chamber moves away ingate 104a and 104b and just be drawn in these two chambers when allowing fluid to flow in the chamber.The independent chamber that each ingate 104a and 104b will for example be connected with thereon with different fluid sources in the container of this device is connected.Optionally, one of them chamber can be from container or external environment condition suction air (or the gas of other form) arbitrarily.In the situation of back, can in device main body, form an air inlet simply, be used for allowing air environment suction from the outside.

Outlet comprises exit passageway and the outlet opening that is formed by

abutment surface

101a and 102a when they contact.Passage is aimed at groove 109,110 and 111 respectively by groove 106,107 and 108 and is formed, and is formed on chamber in the exit passageway and aims at groove 114 and 115 respectively by groove 112 and 113 and form.

Therefore, the fluid that distributes from the chamber that is formed by groove 101b/102b is flowed through by making groove 112/114 aim at the chamber that forms during use, enters before ejecting by outlet opening then by making groove 113/115 aim at the chamber that forms.The fluid that distributes from the chamber that is formed by groove 101c/102c is flowed through by making groove 113/115 aim at the chamber that forms during use, and it mixes with the fluid that distributes from another chamber before ejecting by outlet opening there.

Have been found that the chamber that is formed in the passage is set helps to make the drop that distributes from spray nozzle device to split, and can produce tiny spraying thus.

The exit passageway of deriving from each chamber also will comprise the outlet valve (not shown) that is arranged on chamber upstream, thereby fluid ejects when just the pressure in chamber surpasses a predetermined minimum threshold.This valve can be by being provided with the elastically deformable flap or other member forms in exit passageway, these flaps begin to be out of shape the opening that can therefrom flow through when being used for allowing the pressure of fluid in chamber be in or surpassing predetermined threshold with formation from the pent initial elasticity biased position of passage wherein.

As mentioned above, the trigger-actuated device comprises a handle 401 and a bonding part.When trigger-actuated device 400 is folded on the main body that assembles of spray nozzle device, extend on the upper surface of main body the bonding part, and the

projection

403 and 404 that is formed on the lower surface of bonding part is aimed at the projection that is roughly arch on the upper surface that

part

102c and 102b by top 102 is formed on main body.Therefore the trigger-actuated device is pivotally mounted on the device main body, thereby as operating personnel during towards handle that apparatus main body pulling is extended downwards, the bonding part pivots, and

projection

403 and 404 makes the part 102c on top and 102b respectively towards the part 101b and the 101c strain of bottom.Therefore, will be compressed, and make fluid therein from device, distribute thus by the chamber that these parts limited.The hole 406 that is formed in the handle 401 of device is aimed at outlet, leads to external environment condition thereby export the fluid that ejects from device.

This device also preferably includes seal member, is used for guaranteeing that top and bottom closely link together.In the embodiment shown in Fig. 1, plastics can be molded in above the coupling part to form suitable tight seal. optionally, one of them part is provided with spine's projection, it is around groove and the side that defines the groove/recess of exit passageway, and forming sealed engagement with the groove of corresponding shaping on being formed on relative abutment surface. spine's projection and corresponding groove will closely cooperate and be in the same place, thereby help to make bottom 101 and top 102 to keep mutually tight adjacency.Spine and groove also form a sealing, are used for preventing that fluid is from chamber or exit passageway leaks out and leak out between top 102 and bottom 101.

In optional embodiment, steam leak-off valve can be for being arranged on pillar or the flap in the hole, it can be when having pressure differential strain to open passage, make thus air from the outside environment flow in the container.

A chamber for example is equipped with in the embodiment of air by making groove 101c/102c aim at the chamber that forms therein, these chambers is compressed together make the air-flow that ejects from this chamber mix with the liquid that distributes from another chamber.This mixing will make droplet rupture and help to form fine spray when distributing liquid by outlet.

Fig. 2 A to 2G demonstrates optional embodiment of the present invention, is used for distributing two kinds of liquid simultaneously with the form of spraying.Fig. 2 A and 2B demonstrate the perspective view of this embodiment.As in the embodiment shown in Fig. 1, the main body of this device 100 comprises a bottom 101 and a top 102 (not shown in Fig. 2 A and 2B).On this device main body, be equipped with a trigger-actuated device 400.This trigger-actuated device 400 substantially the same with shown in Fig. 1, except this trigger device comprises a diplopore 406 in addition, be used for allowing two kinds of fluids by two separately outlet 250 and 251 distribute separately.In addition, stay 410 can selectively be arranged between trigger handle 401 and the bottom 101 to prevent that this device accident from actuating. in order to unclamp this locking member, can inwardly push stay 410, thereby the trigger device when being subjected to spurring, it can slip over them.

Can see another modification of this trigger-actuated device at Fig. 2 C, 2D and 2F.Bonding part 402 is divided into two sections 402a and 402b.The same as previously described, section 402a is elastically deformable part 102b and the 102c that is engaging top 102, and section 402b constitutes the rearward recess 270 that is engaging main body.Projection 271-273 helps to make this part to aim at groove 270 and fix, thus help the trigger-actuated device is fixed on bottom on 101.Section 402a is connected by the buckstay 409 that forms pivoting point when spurring the trigger handle with 402b.Therefore, section 402a pivots with respect to section 402b when pulling trigger device, because prevent this region deformation without any retainer between 404 and 409.Therefore, actuator pivots around this coupling part when pulling trigger device. and this is with different in the embodiment shown in Fig. 1, because pivotal point has moved to the position intermediate of close this device along the upper surface of this device. have been found that this provides trigger action more easily, because can simply the trigger device be spurred towards device main body, and the trigger action needs inside and pulls down the trigger action device in the embodiment shown in Fig. 1.

In the disassembly status among Fig. 2 C and the 2D, demonstrate the various piece of the main body that forms spray nozzle device. this internal structure with have many similarities (as representing) by similar reference number in the embodiment shown in Fig. 1, still have some differences.

At first, as shown in fig. 1, top 102 is connected 101 fronts, bottom rather than side.Therefore simply by making Connection Element 103 bent/folded and it being assemblied in the spray nozzle device that on the bottom 101 top 102 upsets is assembled with formation.

The second, also constitute two kinds of liquid of independent distribution in the embodiment shown in Fig. 2 C and the 2D, thereby be used for two kinds of desired independent sprayings of some purposes they are just mixed in the spray nozzle device outside by merging.Certainly it should be understood that in these optional embodiments, exit passageway can constitute according to merge in the similar mode of the exit passageway of the embodiment shown in Fig. 1.

Therefore the exit passageway of each chamber is different with embodiment at Fig. 1 because each chamber comprise by as shown in Fig. 2 G by making groove on the abutment surface 101a bottom being formed on and/or groove 203-211 with groove and/or groove 203a-211a aim at the exit passageway that forms accordingly.

Therefore, in the spray nozzle device that assembles, each outlet comprises an outlet opening and comprises by making groove 203/203a, 205/205a, 207/207a and 209/209a aim at four chambers that form.The chamber of back forms swirl chamber for aiming at by semi-circular recesses 209/209a.Therefore, the fluid that distributes from each chamber passes three expansion chamber and enters swirl chamber along channel flow during use, before ejecting by outlet opening rotating flow is imported in the influent stream body stream thus.Expansion and swirl chamber are known in this area, and are used for before ejecting by outlet fluid drop being broken.
