Definitions
- the present invention relates to a steam iron with a steam generating device for generating steam and an application device for delivering additives to the steam, and a valve device therefor.
- a steam iron is known from DE 296 01 699 U1, in which fragrances are only added to the steam already generated.
- the fragrances are pressurized and sprayed into the steam via a nozzle and mixed into it.
- this solution requires complex pressurization of the fragrances.
- the spray outlet opening can calcify due to the passing steam.
- the present invention has for its object to provide an improved steam iron that avoids the disadvantages of known solutions.
- a reliable and trouble-free introduction of the additives should be achieved with a simple structure of the steam iron. It is also an object to provide a valve device for this.
- the additive does not need to be pressurized.
- the application device has self-regulating dosing means which precisely deliver the desired amount of the additive to the steam.
- the application device advantageously works without a nozzle for atomizing the additive, as a result of which calcification is avoided.
- the additive is dispensed downstream of the steam generating device, in particular in a steam distribution space, and mixed with the steam.
- This has the advantage that no residues can deposit and accumulate on the steam generating device.
- the additive is dispensed in an area in which the additive can mix with the steam and not with the liquid water. This area is preferably not identical to the area where the water drips into the steam chamber, but is only arranged adjacent to it, at a location where the steam flows past on the way to the steam outlet.
- the capillary device is preferably slidably mounted such that it can be brought into and out of a flow path of the steam.
- the capillary device can be removed from the steam flow path, particularly if it is not intended to add any additives to the steam.
- the capillary device can basically be designed differently.
- the capillary device preferably has a capillary wick.
- the capillary wick is advantageously dimensionally stable, in particular pressure-resistant and kink-resistant.
- a seal can be provided for the capillary device, through which the capillary wick can be pushed into the flow path of the steam. In the retracted position of the capillary device, the seal closes the flow path of the steam.
- the capillary device has a capillary knit and a supporting body carrying the capillary knit.
- a braid or fabric or fabric that is optimal for the capillary effect can be used regardless of the mechanical properties.
- the support body provides rigidity and strength.
- the promotion of the additive is effected in the capillary tissue.
- Possibilities There is a wide variety of shapes Possibilities.
- a braided hose is preferably provided, into which the support body is inserted. The internal arrangement of the support body results in an effective delivery of the additives to the steam flowing past.
- the capillary device is expediently designed to be temperature-resistant in order to withstand the heat from the steam.
- a glass silk braid can be provided, the diameter of the individual filaments of the braid preferably being between approximately 5 and 50 ⁇ m.
- the capillary device can in principle be connected directly to an additive store. However, the connection between the additive reservoir and the capillary device is preferably controlled by an intermediate valve device. If no additives are to be dispensed, the valve can shut off the capillary device from the additive store. To dispense additives, the valve enables the connection between the additive storage and the capillary device. This has the advantage that the additives cannot volatilize via the capillary device when the steam iron is out of operation or an operation without the addition of additives is selected.
- the application device can be switched on and off with the valve device.
- the valve device can be constructed in several parts.
- a rubber-elastic shut-off element can be plug-connected to a central valve channel body.
- the valve device is preferably designed as a one-piece component.
- the valve device can be made of a soft plastic, in particular the valve device is a one-piece rubber part, i.e. made of a rubber-elastic material. This results in a simple construction and an uncomplicated assembly.
- An advantageous embodiment of the invention consists in that a shut-off element for shutting off the valve channel extends from a central valve channel body with at least one valve channel, which is designed to be reversible from a manufacturing position into a working position. In the non-inverted position in which the valve can be produced, the shut-off element extends from one side of the central valve channel body in a direction away from the valve channel body, so that the shut-off element forms a kind of platform for the valve channel body.
- the central valve channel body is at least with a portion that contains the at least one valve channel, within a space that is limited by the shut-off element as a peripheral wall cup-shaped.
- the shut-off element In the inverted position, the shut-off element, in particular a sealing surface thereof, is prestressed towards the valve channel body.
- the shut-off element is movable between a shut-off position in which the sealing surface of the shut-off element bears against the valve channel body and a flow position in which the valve channel is in flow connection with the additive reservoir.
- the shut-off element is preferably designed to be snap-lockable or monostable between the shut-off position and the open position.
- the valve device has an intermediate store which is shut off from the additive store when the valve device is shut off and is connected to an outlet side.
- the buffer is filled when the shut-off element is open. After the shut-off element has been closed, only the amount of the additive stored in the buffer can be discharged.
- the intermediate store is preferably formed by a cavity delimited by the valve channel body and the shut-off element.
- a conical sealing fit is expediently provided between them.
- the conical sealing surfaces achieve the high sealing effect even with low preload forces.
- a simple construction of the application device can be achieved in that the capillary device can be attached directly to the valve device.
- the valve device can have a bearing, in particular a receptacle, into which the capillary device can be inserted.
- a storage seal for sealing the additive store is provided integrally on the valve device, in particular the shut-off element can be sealingly connected to the additive store.
- the valve device is designed as a valve head of a storage cartridge, which can be brought into an open position by being pressed into the interior of the cartridge.
- the valve head can be formed in the longitudinal direction above the cartridge housing so that the opening of the valve can be effected by pressure against an end face opposite the head.
- the shut-off element is preferably connected to the cartridge, so that pressure on the elastically prestressed valve channel body releases the valve channel.
- the reverse arrangement is also possible, but the described connection of the shut-off element with the cartridge results in a particularly favorable and simple structure.
- the application device is designed as a separate preassembled exchange unit.
- the application device is therefore removable from the rest of the body of the steam iron. If necessary, this can also be used without the application device.
- the design of the application device as an independent module has the advantage that, when the steam iron is in operation, a choice can be made between the use of different additives quickly and independently of the fill level of the additive store. In particular, draining of an additive previously used from the additive storage and refilling with the desired additive is avoided. In addition, even when the storage device is empty, only the application device as a whole needs to be changed without having to handle the additive directly.
- the steam iron preferably has a corresponding receptacle into which the application device can be inserted.
- the exchange unit advantageously comprises the storage cartridge, the capillary device and the valve head which sits on the storage cartridge and carries the capillary device.
- the application device can preferably be brought into different positions and locked in such a way that the additive delivery of the capillary device can be switched on and off.
- the memory pack trone slidable and lockable, so that the valve head opens and closes and the capillary is pushed into and out of the steam path.
- a locking mechanism is advantageously provided here, which fixes the application device in the desired position.
- the application device can be inserted from above into a recess that is accessible from the outside and opens into a grip area.
- the memory cartridge itself is therefore the control unit of the application device.
- the application device can be brought into flow connection with a spray device for spraying the objects to be processed.
- the additive can be applied to an increased extent on surfaces to be worked particularly intensively.
- the object is achieved with respect to the valve device with the features of claim 24.
- the valve device is advantageously formed from a one-piece rubber-like body, the elasticity and shape of which is used in order to provide the resilient up and down movement.
- an edge of the rubber-like valve device is fastened to the fluid container in such a way that a slight connection is produced by slight deformation. Neither a spring nor a sealing O-ring is required.

- Figure 21 is a schematic sectional view through a valve device which is attached to a baby bottle.
- the steam iron according to FIG. 1 has a housing 1 with a dumbbell-shaped handle section 2, which spans and is connected to a tank section 3 for storing water.
- a heated iron soleplate 4 is arranged, which is usually made of cast metal.
- the soleplate 4 lies under the tank section 3 of the iron housing 1.
- a steam chamber 5 is arranged above the iron soleplate 4 as part of a steam generating device, in which water, which is stored in the tank section 3 of the housing, is converted into steam.
- the water is introduced dropwise from the tank section 3 via a drip valve into the steam chamber 5, in which the water is evaporated.
- the generated steam is discharged via a steam flow channel 6 into a steam distribution chamber 7, from which the steam flows through outlet openings in the underside of the iron soleplate 4 onto the laundry to be ironed.
- a plurality of outlet openings are preferably provided on the underside, which branch off from the steam distribution chamber 7 and are flow-connected to the latter.
- the soleplate 4 and the steam chamber 5 arranged above it can be electrically heated in the usual way, for example by a heating resistor 8, which is indicated schematically in FIG.
- the steam iron has an application device 9 with which an additive can be added to the steam and mixed with it.
- an additive can be added to the steam and mixed with it.
- a liquid, water-soluble additive is released.
- ironing aids, starch, lubricants, plasticizers, cleaning agents, care substances, perfumes and fragrances and impregnating agents can be used as an additive and applied to the laundry together with the steam.
- the application device 9 has a storage cartridge 10 for storing the additive.
- the iron housing 1 has in its grip section 2 or at another location a storage recess 11 into which the storage cartridge 10 can be inserted (cf. FIG. 1).
- the storage cartridge 10 can be inserted in such a way that a bottom of the storage cartridge 10 lies approximately on the outside of the iron housing 1 and can be pressed by the thumb with another finger of an operator in order to put the application device into and out of operation, as will be explained in more detail later will be.
- the top of the storage cartridge 10 is closed with a valve head 12 which controls the outlet of the additive stored in the interior of the storage cartridge.
- the valve head 12 is designed as a one-piece rubber part.
- the valve head 12 has a central valve channel body 13 in which a valve channel 14 is provided.
- the valve channel 14 has an inflow opening 15 which leads from a peripheral side of the valve channel body 13 into the interior of the valve channel body 13 and is connected there to an outflow opening 16 which opens into an end face of the valve channel body 13.
- the inflow opening 15 and the outflow opening 16 extend perpendicular to one another.
- the inflow opening 15 is preferably designed as a radial through hole which opens on opposite circumferential sides of the valve channel body 13.
- the design as a through-hole simplifies production and brings about a rapid flooding of the valve channel 14.
- the valve channel body 13 has a cylindrical channel body 17, in which the valve channel 14 is arranged, and a conical valve section 18, which is essentially frustoconical.
- the conical valve section 18 is attached to the side of the channel body 17 facing away from the end face of the valve channel body 13 and tapers towards the channel body 17.
- the valve channel body 13 is thus undercut from the inside of the storage cartridge 10.
- the conical peripheral surface of the conical valve section 18 is provided as a sealing surface 19 which interacts with a complementary, likewise conical sealing surface 20 of an elastic shut-off element 21.
- the shut-off element 21 is integrally connected to the end of the channel body 17 lying towards the end face of the valve channel body 13 and extends from it in a goblet shape to the conical valve section 18.
- the shut-off element 21 is rotationally symmetrical and surrounds the channel body 17 in a cup shape or likewise essentially rotationally symmetrical.
- the conical or beveled sealing surface 20 is provided, which is in contact with the sealing surface 19 of the conical valve cover. Section 18 interacts.
- the shut-off element 21 is biased towards the conical valve section 18 so that the sealing surfaces 19 and 20 are pressed together.
- the inflow opening 15 of the valve channel 14 opens into a cavity 22 which is delimited on the one hand by the shut-off element 21 and on the other hand by the peripheral surface of the valve channel body 13.
- the cup-shaped shut-off element 21 is designed to be invertible, as shown in FIG. 5.
- the shut-off element 21 does not extend from the end face of the valve channel body 13, in which the outflow opening 16 opens, towards the conical valve section 18, but in the opposite direction beyond the end face.
- the undercut of the valve channel body 13, which later forms the cavity 22 and into which the inflow opening 15 opens is open and freely accessible. This significantly simplifies production.
- the shut-off element 21 is turned or turned over toward the conical valve section 18. With the inversion, the biasing of the shut-off element 21 against the conical valve section 18 can be effected in a simple manner.
- the valve head 12 is placed on the open end face of the storage cartridge 10 on the housing of the storage cartridge 10 and connected to this.
- the connection is fluid-tight.
- a storage seal 23 is arranged at the free end of the shut-off element 21, which cooperates with a corresponding sealing recess 24 on the inner peripheral surface of the storage cartridge 10.
- the storage seal 23 is integrally formed on the shut-off element 21 and is designed as an essentially bead-shaped circumferential web.
- the maximum diameter of the valve channel body 13 is smaller than the inside diameter of the storage cartridge 10 in the region of the valve head 12, so that a circumferential annular gap lies between the valve channel body 13 and the housing of the storage cartridge 10.
- the channel between the valve channel body 13 and the housing of the storage cartridge 10 is shut off by the shut-off element 21, in particular by its free end.
- the sealing surfaces 20 and 19 of the shut-off element 21 and the conical valve section 18 act together (see FIG. 3).
- valve head 12 In order to open the valve head, ie to bring the inflow opening 15 into fluid communication with the interior of the storage cartridge 10, the valve channel body 13 must be pressed into the interior of the storage cartridge 10, so that the free edge of the shut-off element 21 is lifted off the conical valve section 18 and the Annular gap between the valve channel body 13 and the housing of the memory cartridge 10 is released (see FIG. 4). The shut-off element 21 is therefore moved relative to the valve channel body 13 in the axial direction of the storage cartridge 10. As FIGS. 3 and 4 show, the valve head 12 is advantageously designed to project over the end face of the storage cartridge 10, so that to open the valve head 12, the end face thereof only has to be pressed against an opposite end face. It is therefore only necessary to press the end of the storage cartridge 10 against a stop.
- the shut-off element 21 snaps into an open position.
- the storage cartridge 10 In order to close the valve head 12 again, the storage cartridge 10 must be withdrawn again, so that the shut-off element 21 can snap back again.
- the end face of the valve channel body 13 is expediently firmly connected to the opposite end face, for example, this can be inserted in a form-fitting manner in an application opening 25 of the steam distribution chamber 7 or screwed to the wall of the steam distribution chamber 7.
- the application device 9 has as capillary device 26 a capillary wick 27 which is inserted into the outflow opening 16 of the valve head 12 with a precise fit.
- the capillary wick 27 extends through the outflow opening 16 into the area of the inflow opening 15, in order to be washed around by the additive inside the storage cartridge 10 when the valve head 12 is open. With its other end, the capillary wick 27 protrudes from the valve head 12, so that it projects through the application opening 25 into the steam distribution chamber 7 and the steam flows around it.
- the capillary wick 27 in this way sucks the additive through the valve head 12 and releases it via the peripheral surfaces at its protruding end to the steam flowing past.
- the capillary wick 27 basically has a glass fiber braid tube into which a dimensionally stable and rigid support body is inserted, so that the capillary wick 27 is designed to be dimensionally stable and pressure-resistant overall.
- the support body can consist of different materials, for example glass, metal, plastic or ceramic.
- the capillary effect is only achieved in the fiberglass braid tube.
- the glass fiber braid tube can be easily cleaned.
- calcification in the steam path is not possible, since the steam flowing past the capillary made of knitted fabric / glass fiber mesh automatically cleans the capillary and thus keeps it functional.
- a ribbon or rod-like capillary knit / braid is used instead of a glass silk braid tube with a support body.
- an end fixation 28 is provided at each end of the capillary wick 27.
- an open sleeve or a cap closed on one side can be pushed onto the end of the wick and squeezed (see FIG. 10).
- the sleeve or the cap can be made of aluminum or brass, for example.
- a spherical cap can also be applied (see FIG.
- the glass braid in particular when the support body is made of glass, the glass braid can be fused to the glass support body, as a result of which the spherically rounded caps are formed at the ends.
- the ends can also be immersed in a hardening liquid such as a synthetic resin for fixation.
- the capillarity and the flow rate of the additive in the glass fiber hose can be set by several parameters, for example by the appropriate selection of the fiber angle to the longitudinal axis, by the type of yarn, the type of braiding, the thickness of the filaments, the wall thickness of the glass fiber hose and a treatment of the fibers.
- the fiber angle is approximately 10 to 80 degrees to the longitudinal axis.
- the fiber thickness of the glass silk filaments is preferably between 5 and 50 ⁇ m.
- the application device is designed as a separate and removable exchange unit and comprises the storage cartridge 10, the valve head 12 and the capillary device 26.
- the storage cartridge 10 with the valve head 12 and the capillary device 26 pushed forward into the storage recess 11 of the iron housing 1, the valve head 12 being inserted with a steam path sealing section 29 on its end face into the application opening 25, so that the application opening 25 in the wall of the steam distribution chamber 7 is sealed by the valve head 12.
- the capillary wick 27 protruding from the valve head 12 protrudes into the interior of the steam distribution chamber 7 (cf. FIG. 2).
- the storage cartridge 10 In order to effect the delivery of the additive to the steam, the storage cartridge 10 is also used the thumb pressed further into the iron housing 1, so that the valve head 12 opens as described. As a result, the capillary wick 27 can suck the additive out of the storage cartridge 10 and deliver it to the steam passing by.
- a locking device can be provided between the storage cartridge 10 and the iron housing 1, which holds the storage cartridge 10 in the depressed position.
- the storage cartridge can also be depressed only briefly, so that the cavity 22 fills with additive. After the locking element 21 snaps back into its locking position, the cavity 22 acts as a buffer. Only the amount of additive stored in it can get into the steam path via the wick. In this way, an exact dosage of the additive can be achieved in batches.
- a ballpoint pen mechanism (not shown), a bayonet lock or another mechanical device is also provided in a variant, which holds the application cartridge or the valve device bistably in an open or closed position.
- the operation is then analogous to the usual ballpoint pen push button operation, d. H. the cartridge automatically springs into the valve open or valve closed position when pressed.
- the cavity 22 as an intermediate store can also be dispensed with for all the embodiments described, so that a direct switchover is possible.
- the valve device is then designed accordingly.
- the valve device itself is designed such that it is bistable, that is to say it remains stable in two switching positions.
- FIGS. 6 and 7. Another embodiment of an application device according to the invention is shown in FIGS. 6 and 7.
- the same components are designated with the same reference numerals as in Figures 3 and 4.
- the application device differs from the one described above by a two-part design of the valve head 112.
- the shut-off element 121 is formed separately from the valve channel body 113.
- the valve channel body 113 and the shut-off element 121 are sealingly connected to one another.
- the shut-off element 121 has an integrally molded sealing section 30, which is designed as an annular web and is received in a complementary sealing section 31 of the valve channel body 113 and is inserted in a fluid-tight manner.
- a web-like circumferential and projecting seal could also be provided on the valve channel body 113.
- the shut-off element 121 is preferably made of rubber.
- the valve channel body 113 can be made of different materials.
- a cylindrical sealing projection 32 is protrudingly formed on the shut-off element 121 towards the end face of the valve head 112, with which the valve head 112 can be inserted into the application opening 25 of the wall of the steam distribution chamber 7.
- the sealing shoulder 32 is so rigid that when the storage cartridge 10 is pressed down, the sealing shoulder 32 does not buckle, but the shut-off element 121 (see FIG. 7).
- FIGS. 8 and 9 A further embodiment of an application device according to the invention is shown in FIGS. 8 and 9, the same components as in FIGS. 6 and 7 being identified with the same reference numbers.
- the application device differs from that according to FIGS. 6 and 7 essentially in that a steam path seal 33 is provided which is separate from the valve head 212 and which is inserted into the application opening 25 in the wall of the steam distribution chamber 7.
- the vapor path seal 33 has a circumferential groove in which the wall of the application opening 25 can be received.
- the steam seal 33 is thereby fixed axially and radially and closes the application opening 25 in a fluid-tight manner.
- the steam path seal 33 has a central wick opening 34, which is generally funnel-shaped and widens towards the valve head 212.
- the wick opening 34 is closed, i.e. the wick opening 34 is only opened when the wall of the vapor path seal 33 delimiting the wick opening 34 is elastically widened.
- FIG. 9 shows, the capillary wick 27 is pushed through the wick opening 34, wherein the latter is pressed open in order to introduce the capillary wick 27 into the steam distribution chamber 7.
- the provision of a separate steam path seal 33 has the advantage that the steam path is closed even when the application device 9 is removed and the steam can only flow out through the outflow openings provided on the underside of the iron soleplate 4. As a result, the iron can also be operated without problems without the application device 9.
- the shut-off element 121 of the valve head 212 is brought into sealing engagement with the housing of the storage cartridge 10 by means of a screw cap 35.
- the valve head 12 can thus be easily removed from the storage cartridge 10 so that it can be refilled.
- a vent (not shown) is also provided in the storage cartridge 10 for the embodiment according to FIGS. 8 and 9. 3, 4, 6 and 7, a vent 50 is formed in the memory cartridge.
- a rubber-elastic mushroom-shaped flap valve 51 opens the vent 50 at negative pressure in the memory cartridge and otherwise keeps it closed.
- the valve device is provided together with a storage cartridge or another container without ventilation. Then fluid can be pumped out or sucked out of the container or the storage cartridge 10 by axial pumping movement of the shut-off element 21 or a similar resilient section or by suction, that is to say negative pressure at the outflow opening 16.
- the described application device and / or the valve can be used advantageously not only with irons, but generally in connection with steam irons.
- the application device, in particular the valve device, if appropriate in connection with the associated storage cartridge can also be used advantageously for other devices for personal use, for example for hair application devices or oral hygiene devices, oral irrigators (with check valve function), coffee machines or shaving care devices.
- the valve device can be used advantageously in particular in applications with detachable tanks or liquid storage devices. A capillary wick does not have to be connected to the valve device.
- the one-piece rubber valve eliminates the need for multiple seals and springs.
- the application device can also be coupled to a spray device by means of which the additive can be sprayed directly onto the laundry to be ironed via a spray nozzle 36.
- a tank separate from the water tank can be provided as additive storage 37.
- a removable memory cartridge as described above can preferably also be used.
- an additive line 38 which is in fluid communication with the additive reservoir 37, can be coupled via a Venturi nozzle 39 to the water spray device or line usually present in irons (cf. FIG. 12).
- the spraying device has a pump 40 with which water is drawn in from the tank section 3 and sprayed via the spray nozzle 36.
- the venturi nozzle 39 is used to Substance storage 37 additive sucked in and sprayed together with the water.
- a metering device 41 is preferably provided for metering the amount of additive to be sprayed.
- the metering device 41 controls the ratio of sprayed water and sprayed additive, which can in principle be set between 0 and 100%.
- the metering device 41 has an additive valve 42 which is connected to the additive line 38. As FIG.
- the additive valve 42 can be adjusted by means of an operating part 43 which is arranged on the upper side of the handle section 2 and can be operated from there. This enables the ratio of sprayed water and sprayed additive to be controlled. It is particularly advantageous here that both water and additive are sprayed through the spray nozzle 36, so that the nozzle cannot stick or dry by applying additive.
- the application device can also be connected to a suction side of the spray pump 40 and not to its pressure side.
- the additive is not drawn in and sprayed through a Venturi nozzle, but is drawn in directly on the suction side of the pump.
- the pump 40 is expediently designed to be switchable so that it can alternately suck in water from the tank section 3 and the additive from the additive reservoir 37 and spray it via the spray nozzle 35.
- the pump can preferably be switched between three positions, namely a first position in which only water is sprayed, a second position in which only the additive is sprayed, and a third position in which a mixture of water and additive is sprayed.
- spraying water through the spray nozzle 36 prevents it from sticking or drying out.
- the pump 40 is used directly as the metering device.
- a separate additive pump 44 can be provided for the spraying of the additive, which can be put into operation by means of an operating part 45, which is arranged on the front upper side of the handle section 2.
- the discharge of the additive is metered directly by the additive pump 44.
- the pressure lines of the two pumps 40 and 44 open together in the spray nozzle 36, so that both the water from the tank section 3 and the additive from the additive reservoir 37 are sprayed through them.
- the additive reservoir 37 of the application device can be connected to the pressure line of the spray pump 40 via an adjustable valve 46.
- the valve 46 can be designed as an on / off valve, so that it can be switched between the delivery of water and the delivery of additive.
- the valve 46 is preferably designed as a continuously adjustable valve, so that the quantitative ratio between the water to be sprayed and the additive to be sprayed can be adjusted.
- an operating part 47 is provided on the top of the handle section 2, which is connected to the valve 46.
- the coupling of the application device to the spray device of an iron can be provided in addition to the previously described delivery of the additive to the steam discharge.
- valve device Further variants of the valve device and their possible uses are described below.
- the conical valve section is provided with a thin-walled servo sealing surface.
- a conical recess can be provided in the upper end face of the valve section, so that a thin-walled section is created.
- the channel body 17 and the conical valve section are made of a harder material than the spring-elastic shut-off element 21 and the adjoining sealing surface 20. Only the area of the valve device which is due to its clamping as a seal or its resilient, elastic or rebounding behavior requires these material properties.
- the two different material properties can be realized, for example, in the form of a one-piece valve device, which consists of hard-soft plastic injection molding, for example with materials made of two different Shore hardnesses.
- valve section is not conical but disk-shaped.
- no central channel with a channel body is provided, but outflow openings are formed between the then massive channel body and the shut-off element. This is useful if no capillary wick is to be inserted into the valve device, but the valve device is to perform the valve function or check valve function in other devices.
- a tappet can be arranged opposite the solid channel body, through which the valve device can be moved into an opening and infeed.
- the elastic section of the shut-off element responsible for the axial mobility is disc-shaped. Such a valve device 60 is shown in FIG. 16.
- the valve device closes a fluid tank and is attached to the tank in a press-sealing manner with a screw cap.
- the shut-off element 62 does not have a shut-off function here, but rather serves for the elastic, axial mobility of the conical valve section 18, which cooperates sealingly with a counter surface on the container 63 instead of with the shut-off element, on the shut-off element 62 protruding lugs 61 are formed, which are sealing or as Bearings on the counter surface of an opposite part act.
- FIG. 17 shows an application of the valve device in which the outer surfaces 64 of the shut-off element cooperate in a sealing manner with complementary sealing surfaces 65 of the opposite part.
- a tappet 66 pushes the valve device into the open position.
- the ends 66 of the shut-off element can not only be sealingly fastened from the inside to the container or the storage cartridge, for example by means of a clamping ring 67, but instead by means of a correspondingly rotated design, the container can be fastened sealingly from the outside, so as to engage here and in the previously described embodiments.
- a corresponding alternative embodiment is shown in Figure 18.
- FIG. 19a and FIG. 19b show a valve device which is inserted in a tube with a clamping ring.
- This valve device opens automatically as soon as a fluid flow presses against the conical valve section on the inside. In the reverse flow direction of the fluid, however, the valve device locks automatically, since the fluid pressure presses the conical valve section against the sealing surface on the shut-off element.
- the valve device thus represents a check valve that has all sealing connections to the tube, resilient sections and opening and closing sections.
- FIG. 20 shows a valve device in a coffee machine, which only releases the coffee flow to the coffee pot when a coffee pot is inserted beneath it along a sliding cap 70 on the valve device.
- the valve device is fastened below the coffee filter holder 72.
- An elevation 71 is formed on the can lid 73 and cooperates with the sliding cap 70.
- FIG. 21 shows an application of the valve device as a leak-proof suction valve on a baby bottle.
- the functioning of the valve device advantageously corresponds to that of a natural nipple, since the simultaneous pressing and sucking on the Outflow opening of the fluid path is released and after use the valve device automatically snaps back into the closed position due to the spring elasticity.
- the valve device preferably works monostably, the stable state being the closed position.
- a corresponding modification of the valve device for example a spring-elastic shut-off element that is more difficult to move
- only a predetermined amount is provided in the cavity 22, so that the baby is less likely to swallow.
- this valve device can also be used for other drinking bottles, for example for bicycles or in the trekking area.
- valve device can also be used for all personal products that have a removable fluid tank, whereby the valve device only opens the tank when in use in the device (e.g. water purifier, oral irrigator, iron, coffee machine, humidifier, razor) and when removed to refill the tank is automatically closed.
- the valve device can be used for containers from which a certain metered quantity should flow, e.g. in the field of hair cosmetics, dispensers of all kinds, pharmaceutical containers, liquid writing devices, dosing syringes, body care, dentifrices, sunscreens, since a constant amount is always predosed in the cavity 22.
- the valve device can also be used advantageously on pressure cylinders filled with propellant gas.
- the valve device can also be used for liquid-protected electrical switches by utilizing the monostable or bistable states.
