Background technology
This foam chamber is being used for mixing the nursing that forms with the medium that can foam by air or the metered dose dispensers of cleaning foam uses through metering ground output a small amount of (some milliliters).This metered dose dispensers also has described foam chamber and an executive component except an air chamber and a dielectric cavity, by operating this executive component, an operation cover can move between initial position and distribution locations under air chamber volume and the compressed situation of dielectric cavity volume.In addition, metered dose dispensers also comprises a medium pipeline, this medium pipeline has the medium that can foam and inputs to the medium inflow section of dielectric cavity and medium that medium that can foam inputs to foam chamber is derived section from medium deposit device, wherein, a dielectric valve preferably is set in the medium inflow section, this dielectric valve can forbid when executive component is operated, can foaming at least medium back flow in dielectric cavity and the medium that can foam flow out from medium deposit device.In addition, be provided with an air duct, this air duct has an air inflow section and an air is derived section, air inputs to air chamber by this air inflow section, air is derived section by this air and is inputed to foam chamber from air chamber, wherein, an air valve is set in the air inflow section preferably, this air valve can forbid that at least air refluxes by the air inflow section from air chamber when executive component is operated.In addition, be provided with and be used to make the mechanism of medium and air foaming of can foaming, described mechanism is arranged on the inflow region and/or the percolation zone of foam chamber and/or flows out in the zone.
Foamed medium on the meaning of the present invention is to be applicable to any medium of making foam, especially nursing or cleaning foam, can with air or other gas foaming.Except the extremely different liquid of viscosity, also comprise cream, soap, gel, powder, foam cleaner, alcoholic sterilization foam and whipped cream.Preferably relate to cosmetic product or medical product, disinfectant and surface cleaner at this.Therefore, the notion of " medium can foam " always should be understood from broad sense on meaning of the present invention.If mention air, then also can use other any suitable gas certainly.
When using metered dose dispensers, foam by suitable guide of flow by the air and the mixture that forms compiling of medium that can foam through metering ground output foam.At this, decide the mechanism that is provided for foaming on pressure condition and flowing velocity, this mechanism makes air and the medium that can foam mixes and foam under the eddy current that causes that flows.As the mechanism that is used to foam, use porous material basically, for example sieve, silk braid, net or spongy formation thing.But just be difficult to influence foaming degree by the described mechanism that is used to foam, especially be difficult to influence the structure of foam to be obtained thus.
At US 6,082, the foam pump that starts described type is disclosed in 586.This foam pump has be used for foaming a medium and an Air mixing device, and this mixing arrangement is made of porous material.At this net that relates to a braid, grid basically or constitute by mesh.It is arranged in the foamed zones of metered dose dispensers as independent member.But using the shortcoming of porous material is such fact: hardly can the generation effect to the guide of flow of the air and the medium that can foam, because at US 6, disclosed porous material is characterized in that according to definition in 082,586, and flow channel is uncertain on geometric properties.In addition, the described mechanism that is used to foam should be provided with as the structural detail that separates, and thus, makes and the relative trouble of assembling.

In addition, what the mechanism that is used for foaming that mentions in the above should consider is, the described mechanism that is used to foam forms very narrow flow channel for passing their mobile fluids, clings easily when these flow channels for example do not use in the long period or when continuing to use for a long time.This especially becomes problem under the situation of the whipped cream that contains fat, because fat deposition and obstruction flow channel after the long period.The replacing of these porous materials or its cleaning are difficult in the metered dose dispensers carry out owing to they are integrated in by structure with causing.
Verified in addition, what be worth expectation is can influence the characteristic of metered dose dispensers by structural measure, the size or the foaming structure to be obtained of operating physical force for example to be applied.What also can be worth expecting is, for the cost reason, uses the metered dose dispensers of same form, the difference of these metered dose dispensers only to be the selection of the mechanism that is used to foam for different the foamed medium that has different foam characteristics respectively.
Summary of the invention
Therefore, task of the present invention is, the metered dose dispensers of the described type of beginning is provided, and this metered dose dispensers is obtaining simplification aspect manufacturing and the assembling.In addition, should allow by on purpose influencing air and the guide of flow of medium of can foaming is decided on indivedual requirements and decided to come the adapting operation situation with plain mode on the employed medium that foams according to metered dose dispensers of the present invention.
Task of the present invention solves like this: this foam device comprises a foam chamber and is provided with some mobile contact pin along a main flow direction from the inflow region that enters foam chamber to the outflow zone of coming out from foam chamber, and these mobile contact pin are laterally extended with respect to main flow direction basically respectively and formed in foam chamber inside under the situation of a foaming passage that is the labyrinth form that flows and embed mutually.
The mechanism that is used to foam is by forming a mobile labyrinth, promptly constituting by the foaming passage with foaming channel geometry of determining on how much.The foaming channel geometry of determining on how much means at this, guide of flow is not for example to determine by the uncertain guide of flow on how much that is present in usually wherein like that in porous material, silk grid or sieve, but guide of flow especially forms by reproducible geometric properties on manufacture method.Also it should be noted that, the guide of flow of expectation for example can reproducibly form on workpiece by compression moulding die, thus, mobile geometric properties especially also can directly be injected on the member of metered dose dispensers, and needn't porous material or similar material be set as the member that separates at this.The formation of flow channel is carried out with unique course of work using under the situation of a kind of material only thus, and wherein, available plain mode influences the foam characteristics of metered dose dispensers by changing mould, for example so that adapt to other medium that can foam.Therefore, by changing the foam chamber geometric properties, same assembly can be used for different foamed media.Different foam chamber adapters also can be set, can equip other metered dose dispensers assembly selectively with this foam chamber adapter.Therefore, same assembly is only by changing equipment just applicable to extremely different foamed media.
Especially can propose, the foaming channel geometry is shaped like this, make these foaming channel geometry form flow-disturbing seamed edge and/or flow divert zones, the air and the medium that can foam forcibly flow through from these flow-disturbing seamed edges and/or next door, flow divert zone and produce whirlpool when executive component is operated.The flow divert zone is meant the zone of flowing and turning to suddenly of being forced to property guiding.The flow-disturbing seamed edge refers in particular to the body seamed edge, and flow channel cross is abrupt change on these body seamed edges.Produce strong eddy current and/or secondary flow in these two kinds of configurations, described eddy current and/or secondary flow promote the mixing of the air and the medium that can foam and help foam to form the use also capable of being combined of these two kinds of configurations.
Foam chamber selectively has a foam chamber top and a foam chamber bottom and the perforation formation of passage by the slit form in foam chamber top and the foam chamber bottom that foam.Thus, the foam channel geometry of Que Dinging can directly be integrated in the foam chamber in inflow region and/or outflow zone.Manufacturing and assembling that this integrated permission of the mechanism that is used to foam is simplified.What be proved to be favourable guide of flow is, the perforation of slit form outside orientation on diametric(al), wherein, these perforation expansion especially radially outward.
Air duct and medium pipeline preferably directly compiled before foam chamber.But in the configuration of determining of foam chamber, also can compile in foam chamber inside.This situation mainly is, foam chamber is on the first foam chamber spare and/or on the second foam chamber spare, especially have the mobile contact pin that extend in the foam chamber on the foam chamber top and/or on the foam chamber bottom.Stream moving being forced to property of contact pin guiding thus by the air and the mixture that medium constitutes, that flow through foam chamber that can foam, wherein, form the flow divert zone in the zone at lug ends or contact pin edge, these flow divert zones promote foaming by forming strong eddy current.Can propose in addition, mobile contact pin is arranged on the foam chamber top and the foam chamber bottom is gone up and embedded mutually under the situation that forms the foaming passage.Quantity, layout and geometric properties by contact pin can exert an influence to guide of flow at this, can influence the foam forming process thus.
Can propose, foam chamber comprises one first foam chamber spare, especially foam chamber top and one second foam chamber spare, especially foam chamber bottom at least, wherein, mobile contact pin is arranged on the first foam chamber spare and the second foam chamber spare and these foam chamber spares can be combined into foam chamber under the situation in labyrinth that form to flow.Foam chamber two-piece type ground constitutes by the first foam chamber spare and the second foam chamber spare, and thus, labyrinth also can form in closed basically inside, chamber as the labyrinth of flowing, and described labyrinth only combines by two foam chamber spares and produces.In addition, a plurality of first foam chamber spares that respectively have an isomorphism type not also can be provided and a plurality ofly have not second a foam chamber spare of isomorphism type, as long as these foam chamber spares can be to a great extent combination with one another at random, these foam chamber spares just can be incorporated into the foam chamber with different foam characteristics by respective combination.
If foam chamber spare can move relative to each other, then obtain under the situation of not changing foam chamber spare, to influence the possibility of foam chamber foam characteristics under the situation that changes effective foam chamber volume.The flow cross section of flow channel be can change thus and the different viscosity and the foam properties of the medium that can foam adapted to.In order to realize this relatively moving property, foam chamber spare is can be by screw thread coupled to each other or can be connected to each other in the mechanism of diverse location by being used for kayser.Screw thread can be realized step-less adjustment, and locking mechanism only allows limited quantity allocation really.
By different positions---foam chamber spare can be realized the difference in functionality of foam chamber because it can move relative to each other and can reach in the described different position.For example foam chamber spare can be transferred in the rest position, and in this rest position, the output of the medium that can foam is prevented from.This for example can realize like this: the such near-earth of foam chamber spare moves toward each other, makes foaming channel seal ground seal, and promptly effectively the foam chamber volume is reduced to zero.Another implements significant position is the percolation position, in this percolation position, opens to this degree of foaming passage, and makes cleaning medium not discharge from foam chamber with foaming.Can create a kind of possibility that between the medium that can foam is exported with foaming and exported to foaming, makes one's options to the user thus.When being provided with screw thread between the foam chamber spare, this especially can by rotate an operating parts for example action button realize.After foam chamber spare is transferred in the percolation position, air duct should on certain position, preferably derive in the section or in air cylinder, open, so that make the air that compresses by the operation of executive component can overflow and operate constant difficulty towards outside environment at air.
The mobile contact pin of foam chamber inside preferably alternately extend into the foam chamber from foam chamber spare.Therefore, the mobile labyrinth of expectation forms under the situation that forms the flow divert zone with plain mode.In a preferred implementing form, the contact pin of flowing constitutes by concentric ring-type contact pin.This for example by air and can foam mixture or air that medium constitutes and the medium that can foam flow in the foam chamber apart from each other and forming under the situation of foam this foam chamber of percolation from outside to inside.The foam outlet preferably is arranged in the foam chamber bottom at the center.
Another possible configuration proposes, on the contrary the contact pin of flowing extend to from the foam chamber bottom always the foam chamber top and/or.In the case, the contact pin of extending from the foam chamber bottom preferably rests on the opposed foam chamber top hermetically with the distolateral of them, wherein, can be provided with perforation at the bottom of the contact pin and/or in the distolateral zone, these perforation can mixed thing percolation under the situation that forms foam.But perforation also can be arranged on other position of the contact pin of flowing.In simple terms, form a mobile labyrinth by contact pin, this mobile labyrinth is passed in the air and being forced to property of the medium guiding of can foaming.
Except the operation cover, also can be provided with a medium deposit device closure member, wherein, on the operation cover, be configured with an air slide and a medium piston, on medium deposit device closure member, be configured with an air cylinder and a medium cylinder, wherein, the operation cover can be seated on the medium deposit device closure member, and air slide and air cylinder and medium piston and medium cylinder form a piston/cylinder unit respectively.Certainly, the setting of cylinder and piston also can be conversely, and thus, cylinder configuration is to medium deposit device closure member, and cylinder disposes to the operation cover.The constructor cover has advantage with medium deposit device closure member dividually: the operation cover arrangement becomes member separately, and the medium deposit device that is made of plastic containers usually can directly seal and sell by a closure member that is configured to medium deposit device closure member.The medium piston is preferably configured as the part of hollow cylindrical and formation medium pipeline itself at this.At this, the medium piston is embedded in the medium cylinder and also forms the inwall of dielectric cavity with this medium cylinder.Corresponding form of implementation also is applicable to the piston/cylinder unit that is used to carry air certainly.
Another configuration of metered dose dispensers proposes, and dielectric valve comprises a valve body on it deviates from the end of medium deposit device, and this valve body is expanded with respect to valve body at the bottom of this valve have a valve on it also deviates from the end of medium deposit device at the bottom of at least in part.Be used herein to the acting in conjunction of dielectric valve and medium piston at the bottom of the valve, but wherein do not bear any sealing function at the bottom of the valve, but only be used for making dielectric valve to remain on the position reliably.In order to promote the acting in conjunction of medium piston and dielectric valve, the medium piston its have on the end that the medium inflow section points to blocking mechanism, especially inwardly stretch stop bead, described blocking mechanism cooperates in the back towards the direction of medium deposit device at the bottom of by valve.The kayser projection of a plurality of outside sensings for example can be set at the bottom of the valve for this reason.
Dielectric valve preferably has one at the valve head of laying in taper that device is expanded to the direction of dielectric cavity, preferred from medium at it on the end that medium deposit device points to, this valve head is connected with valve body by a valve neck, and this valve neck has the little cross section of cross section than another end of valve head.This configuration of valve head allows dielectric valve with suitable manner and medium cylinder acting in conjunction.For this reason, medium cylinder is connected with medium deposit device by a hole on the end that medium deposit device points at it, and wherein, valve head extends through this hole and can enclose hermetically in distribution locations at least and acts on one and be configured on the maintenance edge of locating in this hole.The medium that can prevent from thus to foam flows out undesirably from medium deposit device and enters into dielectric chamber (otherwise perhaps).Especially the cross section of the expansion by valve head can make this valve head more easily be inserted in the hole when the assembly manipulation cover.
Propose in addition, the valve neck is forming one under the situation of the shell face of the outside of the direction expansion of valve body, preferably forming under the situation of shell face of a taper and carry out the transition to valve body.When executive component was operated, this shell face can rest on the hole the medium cylinder and as valve sealing surface from the dielectric cavity side and work, and forbade foaming medium back flow thus in medium deposit device.
Especially operation cover, medium deposit device closure member and foam chamber are investigated to essence of the present invention together with the single component of foam chamber structural detail also conduct and metered dose dispensers disengaging and itself are considered to the invention prescription.

Engage and form an air chamber 2 and a dielectric cavity 3 by operating cover 6 and medium deposit device closure member 21, this air chamber and this dielectric cavity can be compressed when executive component 5 is operated, this executive component this for example the housing shell of the outside by operation cover 6 constitute with the form of action button 5.Executive component 5 is not to be configured to one with operation cover 6, but can constitute by other device that is used to operate yet, and especially constitutes by lever or similar device.Conclusively only be, can cause the compression of dielectric cavity 3 and the compression of air chamber 2 by executive component by the user.As shown in fig. 1, advantageously, action button 5 is stretched out the lateral edge above medium deposit device closure member 21, is clamped so that avoid finger to wait.
Be configured with an air slide 22 and a medium piston 23 on operation cover 6, this air slide and this medium piston can be inserted into respectively in the medium deposit device closure member 21.Medium deposit device closure member 21 that inwardly point to, a preferred columned face respectively is provided with the air cylinder 24 and the medium cylinder 25 that is configured to hold medium piston 23 that are configured to hold air slide 22.Air slide 22 and medium piston 23 have a piston sealing device respectively on it is inserted into lower edge zone in the respective cylinder, described piston sealing device in these figure as a whole structural detail be injected at integratedly separately on the piston.Piston sealing device is configured to sealing lip at this, and the sealing lip prevents that the air medium that maybe can foam from overflowing when 3 compressions of air chamber 2 or dielectric cavity.Sealing lip also can be used as independent member certainly, preferably makes as the member made from flexible plastic.
In addition, be provided with an air duct 11 in operation cover 6, this air duct has an air inflow section 12, and air can arrive the air chamber from air valve 14 next doors process by this air inflow section.Another part of air duct 11 derives section 13 by air and constitutes, this air derive section from air chamber 2 towards foam chamber 4 direction extend.By being configured in the medium cylinder 25 in the medium deposit device closure member 21 and constituting a medium pipeline 7 by the medium piston 23 that is configured in the operation cover 6, this medium pipeline has a medium inflow section 8, and the medium that can foam arrives the medium pipeline 7 from medium deposit device (not shown) by this medium inflow section.In addition, have a medium in the zone of medium pipeline 7 before directly being in foam chamber 4 and derive section 9.
As appreciable among Fig. 1, air duct 11 and medium pipeline 7 directly compiled before foam chamber by the guide of flow device that is provided with.Form a kind of premixed chamber thus, in this premixed chamber air and can foam medium do not foam ground and deposit.
Medium pipeline 7 especially constitutes with the form of columned pipe basically, and the inner surface of this pipe not only constitutes by the inner face of medium piston 23 but also by the inner face of medium cylinder 25.Form of implementation shown in Fig. 1 has medium inflow section 8 and medium that is used for foaming that the medium that is used for foaming is input to dielectric cavity 3 derives section 9 from the medium that dielectric cavity 3 derives, this medium inflow section and this medium are derived section and are overlapped with the part of dielectric cavity 3 respectively, and described medium pipeline section 8,9 also can constitute with the flexible pipe that do not overlap with dielectric cavity 3 or the pipeline of other form.Especially can realize some configurations thus, in these configurations, foam outlet and medium deposit device 21 is such to be spaced from each other far awayly, makes the medium that can foam must at first derive section or medium by a medium from dielectric cavity 3 and import section 9 and be directed to foam chamber.Certainly same design also can be diverted to by air duct 11 and carry air.
Fig. 2 shows the detailed view of foam chamber 4 and the layout in metered dose dispensers thereof with the local A among Fig. 1.The mixture that is made of the air and the medium that can foam is incorporated into the foam chamber 4 by some foaming passages 15 from medium derivation section 9, and the body seamed edge of these foaming passages constitutes flow-disturbing seamed edge 16.Foaming passage 15 is arranged in the foam chamber top 18 at this.In addition, foam chamber 4 has a foam chamber bottom 19, also is provided with some foaming passages 15 in this foam chamber bottom, and these foaming passages have the guide of flow device of determining on how much.
Quantity and size by influence foaming passage 15 can influence foam formation, especially foaming structure.The cross section of foaming passage 15 not only can be on diametric(al) towards foam chamber top 18 or the center of foam chamber bottom 19 change, and can be in originally variation on one's body of flow direction.Therefore especially can propose, on flow direction, reduce or expand the flow cross section of foaming passage 15.Can improve flowing velocity thus and can strengthen the eddy current that produces when flow-disturbing, this is necessary for forming foam.
Therefore the foaming channel geometry of foaming passage 15 should be constructed like this, makes to form the flow-disturbing seamed edge, and the air and the medium that can foam forcibly flow through from these flow-disturbing seamed edges next doors and produce whirlpool when executive component 5 is operated.Shown in especially cancelled the necessity that another structural detail that is the porous material form (sieve, silk braid, grid, net) is set in the configuration.In Fig. 2, the foam passage for example constitutes by the perforation of slit form, and these perforation are outwards pointed on diametric(al), wherein, and these perforation expansion radially outward.
Fig. 1 has illustrated a dielectric valve 10 in the medium inflow section 8 of medium pipeline 7.This dielectric valve has a valve head 28, valve neck 29 and one as from Fig. 3 at the bottom of the appreciable valve 27, they are connected with valve body 26 respectively.
Valve head 28 is made of a truncated cone at this, and this truncated cone passes one makes medium pipeline 7 stretch out with the hole 33 that medium deposit device is connected.The valve head 28 of taper rests on one at this and keeps on the edge 34 or suspending in scheme upside down being bearing on this maintenances edge with its downside, wherein, keep edge 34 edge formation by hole 33 for example under present case.Valve head 28 makes hole 33 sealings at this from medium deposit device side, can avoid thus can foaming media flow in dielectric cavity 3.Valve neck 29 extends with the cross section that significantly reduces from valve head 28, and this valve neck is forming one under the situation of the shell face 30 of the outside of the direction expansion of valve body 26, preferably forming under the situation of shell face 30 of a taper and carry out the transition to valve body 26.As following also want as described in, the shell face 30 of this taper is as sealing surface, the sealing face medium that prevents to foam is back to the medium deposit device from dielectric cavity 3.
In addition, the back that valve head 28 acts on hole 33 acts on the back at the maintenance edge that is configured on the hole 33 in other words and only is connected with valve body 26 by narrow valve neck 29, can realize that thus operation cover 6 can not be laid in device closure member 21 from medium and take off under the situation that dielectric valve 10 does not damage.If metered dose dispensers 1 is configured to disposable object, then this can be significant because disposable object, make the scope of application according to the scope of application of its limited setting and design like this double that to be accompanied by its function significantly limited.If but could not without damage take off operation cover 6, then should forcibly replace whole system, so that prevention is for example owing to the wearing and tearing or the thrashing that causes of transshipping.In addition, separately medium deposit device closure member 21 and medium deposit device or operation cover 6 can be supported to avoid without damage in commercial aspect or quality guarantee aspect, especially when the third party enterprise overdue delivery that should avoid for the above reasons can not exerting an influence to product quality.
In the metered dose dispensers shown in Fig. 1 to Fig. 5, prevent medium deposit device closure member 21 and medium deposit device or the operation cover 6 above-mentioned possibilities of without damage separating especially can by make medium deposit device closure member 21 and medium deposit device inseparable turn up the soil to link to each other fetch realization.For this reason, can abandon on the medium deposit device closure member 21, at the screw thread shown in Fig. 1, and this medium deposit device closure member can be placed in by suitable mechanism on the medium deposit device, for example bonding, is connected with device welding of this medium deposit or by the buckle that can not unclamp and lays in device with this medium and be connected.By force medium is laid in device closure member 21 and medium deposit device and thrown off and then can cause being connected and may damaging between medium deposit device and the medium deposit device closure member 21, this can get rid of one of these members by once more or continue utilization.Operation cover 6 separate with medium deposit device closure member 21 and also can cause valve to damage, and this also can cause the member of metered dose dispensers to damage, and promptly can not allow metered dose dispensers or each assembly by once more or the continuation utilization.
Fig. 3 shows another detailed view among Fig. 1 with local B.The bottom of the main body 26 of dielectric valve 10 is provided with at the bottom of the valve 27, at the bottom of this valve with respect to valve body 26 in expansion aspect the clean cross sectional dimensions of its outside.For this reason, 27 have some kayser projectioies 32 at the bottom of the valve, these kayser projectioies be engaged in blocking mechanism, especially inwardly stretch be configured in the back that stops bead 31 on the medium piston 23.Thus, dielectric valve 10 remains in the position.In addition, when distribution locations (Fig. 5) carried out the transition to the initial position (Fig. 4), kayser projection 32 was blocked that bead 31 is caught and dielectric valve 10 is transferred in its given position that is set for initial position under the support of medium piston at operation cover.At this, have at the bottom of the valve of the kayser projection 32 on being arranged at the bottom of the valve 27 and do not bear sealing function.But construct like this at the bottom of this valve, make can foam medium can flow at any time pass valve body 26 or have the valve of kayser projection 32 at the bottom of 27 and stop between the bead 31.
Should be mentioned that in addition at the bottom of the valve 28 and the length of valve body 26 for the unblemished function of dielectric valve 10, have little significance.Even and for example abandon making the kayser projectioies 32 of 28 expansions at the bottom of the valve fully, the function of dielectric valve 10 also is met.And meaningfully, dielectric valve 10 is constructed like this, makes that especially this dielectric valve sealably rests on the hole 33 when the dielectric cavity as a result 3 that is depressed as executive component 5 is loaded pressure, so that the medium back flow that prevents to foam is laid in the device to medium.Dielectric valve 10 should topple at this.
Fig. 4 shows the metered dose dispensers 1 that is in the initial position.At this, with the arrow mark air and the medium that can foam, at operation cover 6 flow paths that when distribution locations (Fig. 5) moves to the initial position, obtain, wherein, flow process already pauses certainly in the actual initial position that illustrates in Fig. 4.And Fig. 5 shows the flow process during executive component 5 is operated, and also uses the arrow mark.The air medium that maybe can foam is forced out from air chamber 2 or dielectric cavity 3.
The diverse location that can see in Fig. 4 and Fig. 5 of dielectric valve 10 is the result of the pressure condition that produced at this.Be operated and therefore be inserted into result in the medium cylinder 25 by executive component 5 as medium piston 23, the dielectric cavity volume reduces, and the pressure that produces in dielectric cavity 3 forces dielectric valve 10 to be pressed towards the maintenance edge 34 that is arranged on the hole 33 with the shell face 30 of its taper.Medium now can not be again escape into the medium deposit device from dielectric cavity 3 because can foam, so this can foam medium flow in the foam chamber 4 by medium pipeline 7 and there with derive section 13 by the air of air duct 11 and be foamed into foam towards foam chamber 4 flow air.So the foaming passage 15 of foam from foam chamber bottom 19 discharged and taken out the hole by foam and flow to the user.
When executive component 5 was unloaded, operation cover 6 turned back in the initial position, and wherein, the cubical expansion of piston/cylinder unit and new air or new foamed medium are inhaled in air chamber 2 or the dielectric cavity 3.At this, rest on to valve head 28 temporary transient blow-by on the maintenance edge 34, thus, the medium that can foam can be from dielectric valve 10 next doors through flowing to the dielectric cavity 3.
Fig. 6 and Fig. 7 show the configuration of two possible schemes as an alternative of foam chamber 4.Be provided with the mobile contact pin 20 that some form flow channel in foam chamber 4 inside shown in these figure.With paint among the figure into arrow represent that air derives section 13 is derived 9 processes of section from the medium of medium pipeline 7 by the foam chamber 4 or the medium that can foam flow path from the air of air duct 11.
In Fig. 6, not only on the foam chamber top 18 but also foam chamber bottom 19 is provided with the mobile contact pin 20 of rounded ring-type contact pin form, these mobile contact pin from foam chamber top 18 or foam chamber bottom 19 vertically downward or extend upward and embed mutually.Fluid feeds in the tap hole of central authorities, and foam can be discharged by this tap hole.
In Fig. 7, also be provided with the mobile contact pin 20 of contact pin form in the form of a ring, although these mobile contact pin only are arranged on the foam chamber bottom 19, upwards extend to foam chamber top 18 and resting on hermetically to a great extent on this foam chamber top with them by putting face always.The different parts of mobile contact pin 20 is provided with perforation, and the air and the medium that can foam can pass these perforation and flow.So that last also being arranged in the central tap hole at one is forced out from foam chamber 4 as foam.Foam chamber structure shown in Fig. 7 also can design like this: perforation is extended on the whole height of contact pin 20 that flows.Mobile contact pin forms some independent pillars thus basically, and the air and the medium that can foam are directed around these pillars.In addition, also can consider the cooperatively interacting of configuration of maze-type structure or a plurality of schemes as an alternative.
The common ground of the form of implementation of Fig. 6 and Fig. 7 is that the air and the medium that can foam inwardly flow on diametric(al) with respect to foam chamber 4.At this, inwardly propelling is far away more on diametric(al), and effectively flow diameter is just more little, thus, and towards the flowing velocity increase of foam chamber center direction.This forms foam can have positive role.In the configuration according to Fig. 7, each perforated flow cross section that is arranged in the contact pin of flowing can be selected according to desired flow behavior and according to desired pressure condition, can influence this effect thus.Thus, the flow cross section that uses for air/medium mixture can almost at random be regulated according to the distance that exports to foam stream.
The design that realizes in Fig. 6 and foam chamber shown in Figure 74 also can be diverted to almost other geometric properties arbitrarily certainly.
Foam chamber bottom 19 is fixed on available different modes carries out on the foam chamber top 18.But specially suitable is to connect by kayser foam chamber bottom 19 is snapped on the foam chamber top 18.The interested fixedly possibility changing or take off easily easily of especially allowing.This is significant for cleaning and repacking purpose.
For operation cover 6 is turned back in the initial position, certainly resetting-mechanism can be set, for example around member setting of metered dose dispensers and helical spring that operation cover 6 and medium deposit device closure member 21 are worked.Also can be provided with and be injected at material continuation on the member, that play reset response or diaphragm integratedly, described material continuation or diaphragm make operation cover 6 automatically reset to the initial position from distribution locations.
Another scheme of foam chamber 4 has been shown among Fig. 8.Foam chamber bottom 19 and foam chamber top 18 are coupled to each other by a screw thread.This allows to change the distance between these two foam chamber spares.Position shown in Fig. 8 is a foam positions, and in this foam positions, not only the air but also the medium that can foam can flow in the foam chamber 4.In this position, the function of the foam chamber among the function of foam chamber and Fig. 6 or Fig. 7 is identical.
Described screw thread allows foam chamber spare to transfer in other position now, and foam device obtains different functions by these positions.In Fig. 9, foam chamber spare quilt is combined pressure and mutual to hermetically putting each other.Foam chamber is in the rest position, and in this rest position, the output of the output of the medium that can foam and preferred air is under an embargo.In the inflow region of air duct 11, promptly to derive in the section 13 at air, a regional seal ground at foam chamber top 18 is in before the air duct and prevents that air from entering into foam chamber 4.Simultaneously, the mobile contact pin 20 of a foam chamber spare rests on another foam chamber spare hermetically.Thus, the medium that can foam also can not flow in the foam chamber 4 again.Effectively the foam chamber volume is reduced to zero.
If the foam positions from Fig. 8 is reversed foam chamber spare so toward each other, make these foam chamber spares move each other with deviating from, then foam chamber 4 is transferred in the percolation position shown in Figure 10.At this, a zone of a foam chamber spare is in air duct 11 with resealing or air is derived before the section 13.Also realize: when metered dose dispensers is operated, do not have air can enter into foam chamber 4.But different with rest position shown in Fig. 9, in the position of percolation shown in Figure 10, do not stop the medium that can foam to flow in the foam chamber.And by foam chamber top 18 is realized away from foam chamber bottom 19: the medium that can foam, especially nursing or cleaning medium are in the clear and with under the situation that air contacts do not exporting.The contact pin 20 of flowing is provided with like this, makes these mobile contact pin discharge the flow circuits in a unconfined flow seamed edge or flow divert zone in the percolation position, and medium is this flow circuits of percolation under the situation of no big flow resistance to a great extent.
Usually, when having the metered dose dispensers that is in the foam chamber in the percolation position according to Fig. 8 to Figure 10 when being operated, the air in the air cylinder 24 also is compressed and carries towards the direction of foam chamber 4.But because the percolation position, be closed from air duct 11 or transition from air derivation section 13 to foam chamber 4, so air must otherwise be drawn, because otherwise can in air slide 22 or at the air of air duct 11, derive and set up the pressure that may react on operation in the section 13.Therefore, when foam chamber 4 is in the percolation position, air duct 11 need be opened towards outside environment in the zone of air cylinder 24 and/or in the zone of air derivation section 13.This for example can guarantee like this: move relative to each other and member thereupon moves release aperture in metered dose dispensers by foam chamber spare, air can freely be overflowed by these holes.
