Definitions
- the invention relates to a hair removal device specified in the preamble of claim 1.
- a hair removal device of the type mentioned at the outset is known from FR 2 613 975 A1.
- a liquid container is arranged in the housing of the dry shaving apparatus, from which liquid is sucked in via a pump device and transported under pressure to two spray devices which are arranged at a distance from one another in the shear region.
- this liquid transport system is started up, irrespective of whether the shaver is in contact with the skin or not, the liquid provided here is dispensed from the spray device.
- the invention has for its object to improve the liquid transport system with respect to the dispensing of liquid in a device of the type mentioned.
- the invention used in the hair removal device has a number of advantages.
- An essential advantage of the invention is that by means of the liquid transport system provided, position-independent liquid removal from the liquid container is ensured by the liquid dispensing device.
- the liquids to be stored and dispensed are to be understood as shaving aids, e.g. Pre-shave or after-shave and / or lubricants to improve the sliding movements of an upper knife on the skin and / or lubricants to lubricate interacting cutting elements with or without fragrance additives.
- both air and liquid can be sucked from the pump device and conveyed into the liquid container from the liquid dispensing device, and the liquid can be transported into the liquid dispensing device by building up a delivery pressure in the liquid container.
- This measure ensures that a pressure in the liquid container for conveying the liquid from the liquid container into the liquid discharge device is constructed and from the liquid dispensing device, provided that no dispensing of liquid from the liquid dispensing device to a skin to be treated by a user takes place, is conveyed back into the liquid container by the pump device.
- a pressure relief valve is provided in the liquid container to control the delivery pressure of liquid and thus also to control the amount dispensed.
- At least two chambers are provided in the liquid container.
- a first chamber is provided for receiving air and / or liquid which can be recycled from the liquid dispensing device.
- a storage material for the liquid is provided in the second chamber.
- at least one passage opening is provided in the partition wall separating the first and second chambers. The passage opening is preferably designed in the form of a gap.
- a preferred embodiment of the invention is characterized in that a liquid line is passed through the passage opening and a gap is formed between the liquid line and the partition.
- This measure advantageously ensures that the liquid sucked out of the liquid dispensing device can flow through the first chamber into the second chamber for storage in the storage material provided there, and the air sucked in by the pumping device also via the liquid dispensing device in the first chamber one from the pressure relief valve can build up controlled pressure, which then transports the stored liquid from the storage material via a second liquid line into the liquid dispensing device.
- the second chamber can be coupled to the liquid dispensing device via a second liquid line.
- the second liquid line projects so far into the second chamber that the line opening is arranged at a relatively small distance B from a wall of the liquid container. This measure ensures that the entire liquid shaving aid stored in the storage material can be extracted and the liquid dispensing device can be transported.
- the second liquid line is preferably designed as a riser pipe.
- the pump device is provided in the first liquid line leading from the liquid dispensing device to the liquid container.
- a particularly advantageous embodiment of the invention is characterized in that the pump device is arranged in the liquid container and that the pump device with the exchangeable liquid container can be replaced together with a new liquid container with pump device.
- the performance of the pump device is therefore designed only for the amount of liquid to be dispensed from the liquid container.
- the quality requirements to be imposed on the pumping device are therefore extremely low and consequently result in an extremely inexpensive manufacture of the pumping device and liquid container.
- a pump element of the pump device can be acted upon by a drive element of a drive of the hair removal device, which drive element can be switched on and off.
- the pump element of the pump device can also be operated by hand.
- a liquid dispensing device is characterized in that the liquid dispensing device is formed from a container that is open on one side and a contact element that can be dispensed from it, in some cases protruding from the liquid.
- the contact element is preferably formed from an open-pore material.
- a rinsing chamber is provided in the liquid dispensing device. The rinsing chamber advantageously ensures that liquid is fed into the open-pore material of the contact element and that suction and thus the return of liquid supplied via the second liquid line is returned to the liquid container via the first liquid line and via the pumping device.
- An advantageous embodiment of the invention is characterized in that at least one liquid dispensing device is provided on the housing.
- An alternative embodiment of the invention is characterized in that the liquid dispensing device is provided on a long hair cutting system. This long hair cutting system can preferably be arranged in a floating manner.
- at least one liquid dispensing device is provided on a removable frame.
- the frame is preferably designed as a shaving head frame.
- the frame is designed as a knife frame.
- the liquid dispenser may be fixedly or removably attached to the housing or to the long hair trimmer system or to the removable frame.
- the liquid container is arranged interchangeably in or on the hair removal device. In a further embodiment of this embodiment it is provided that the liquid container is fixed in or on the housing. According to an alternative embodiment, it is provided that the liquid container is arranged adjustable in or on the housing by a distance A.
- the liquid container is equipped with a filling valve.
- the liquid container with the pump device is arranged adjustable by a distance A.
- a major advantage of this embodiment is that the pump device can be both separated and switched on by means of the adjustability of the liquid container and the pump device from an electric drive of the hair removal device. This measure ensures that the user can determine the use and the duration of use of the liquid dispensing device.
- the liquid container can be coupled to the pump device with the electric motor.
- the pump device can be coupled to the electric motor via oscillating elements.

- the actuating element 27 is provided with a marking M on the adjusting element 26, which is slidably mounted within the container housing 21 and protrudes from the container housing 21 from an elongated opening 28.
- the actuating element 27 can be displaced with the marking M parallel to a scale SK provided on an outer wall of the housing part 212.
- the open-pore contact element 22 provided with a rinsing chamber 214 is fixedly arranged in an interior 213 of the housing part 211.
- the housing part 211 is arranged adjacent and parallel to the longitudinal extent of the upper knife 18, such that the contact element 22 arranged in the interior 213 and partially protruding from the interior 213 can dispense liquid adjacent to the upper knife 18.
- the spacer 23 relative to the contact element 22 - see FIGS. 5 and 6 - the contact surface of the contact element 22 that is used in each case can be changed and thus the amount of liquid dispensed can be controlled.
- the liquid to be dispensed by the contact element 22 of the liquid dispensing device is supplied to the contact element 22 via a second liquid line 32.
- the metering of the liquid to be dispensed through the contact element 22 can also be controlled by sucking off liquid from the liquid dispensing device 4 via a first liquid line 31.
- FIG. 7 shows a schematic illustration of a liquid transport system from the liquid container 5 to the liquid dispensing device 4 and from the liquid dispensing device 4 back into the liquid container 5.
- a partition wall 42 is provided in the liquid container 5 to form a first chamber 40 and a second chamber 41.
- An opening is provided in the partition 42.
- a second liquid line 32 is guided through this opening and ends at a predetermined distance B from the bottom 46 of the liquid container 5.
- the size of the opening in the partition 42 is dimensioned such that a gap 43 is formed after the second liquid line 32 has been passed through. This gap serves to supply liquid from the first chamber 40 into the second chamber 41.
- a porous storage material 44 e.g. sintered material - intended for storing liquid.
- the first chamber 40 is connected via a liquid line 47 to a pump device 13 provided outside the liquid container 5.
- the pressure required to convey liquid from the second chamber 41 can be produced by means of a pressure relief valve 45 via the second liquid line 32 acting as a riser pipe into the liquid dispensing device 4.
- the pressure relief valve 45 can consist, for example, of a tube with an opening whose cross-section is dimensioned such that the atmospheric pressure required for conveying the liquid can be reached after the pump device 13 has been started up, and any excess pressure that can exceed it can be released.
- a contact element 22 is fixedly arranged in the container housing 21 of the liquid dispensing device 4.
- a rinsing chamber 214 is provided in the contact element 22, into which liquid 32 is transported via the second liquid line.
- the pressurized liquid penetrates into the open-pore material of the contact element 22 and is released to the skin through a skin when the outer contact surface 48 is touched, as is indicated by the arrows.
- the rinsing chamber 214 is coupled to the inlet side E of the pump device 13 via a first liquid line 31.
- the outlet PA of the pump device 13 is coupled to the first chamber 40 of the liquid container 5 via a liquid line 47.
- the pump device 13 When the pump device 13 is started up, it sucks both air through the container housing 21 - see arrow L - and liquid from the rinsing chamber 214 and / or the contact element 22 and transports it into the first chamber 40, where it builds up the pressure required for transporting Liquid from the second chamber 41 via the second liquid line 32 into the rinsing chamber 214.
- the liquid delivery of the contact element 22 can be controlled in such a way that that liquid is released to a skin to be wetted only by touching the contact surface of the contact element 22. A dispensing of liquid without touching the contact element 22 therefore does not take place.
- the gap 43 between the partition wall 42 and the second liquid line 32 designed as a riser pipe is dimensioned such that the liquid transported by the pumping device 13 into the first chamber 40 can penetrate into the storage material 44 of the second chamber 41. A backflow of liquid stored in the storage material from the second chamber 41 via the gap 43 into the first chamber 40 is prevented by means of the binding effect of the liquid on the storage material 44.
- Fig. 8 shows the liquid transport system according to Fig. 7 with the difference that the pump device 13 inside the liquid container 5, i.e. is provided in the first chamber 40.
- the pump device is part of the liquid container 5 and can be exchanged with it.
- the interchangeability of the liquid container 5 can be produced by coupling the first liquid line 31 and the second liquid line 32 to the liquid container 5 by means of corresponding coupling elements - not shown. Coupling elements of this type can also be provided in the first liquid line 31 and the second liquid line 32 according to FIG. 7 in order to couple the pump device 13 and the liquid container 5 to them.
- a rubber molded part is used as the lid of the liquid container 5, which seals the complete unit including the first and second liquid lines 31, 32 tightly.
- the metal tips of the first and second liquid lines 31, 32 located in the housing 1 pierce the cover in the line area when the cleaning liquid container is inserted and release the liquid circuit.
- the described structure of the liquid container 5 can preferably be carried out as a disposable cartridge or a container that can be filled in or on the hair removal device.
- FIG. 9 shows a schematic representation of the arrangement of a liquid transport system according to FIG. 7 in a dry shaving apparatus TR according to FIGS. 1 and 2.
- the contours of the dry shaving apparatus are represented, for example, by dot-shaped lines.
- An electric motor 50 is arranged in the housing 1 of the dry shaving apparatus TR, the motor shaft of which is coupled via an eccentric to an oscillating element 52 in order to set the oscillating element in oscillating movements - see arrow directions S1 and S2.
- the swing bridge 52 is used to drive cutting elements of the dry shaving apparatus TR - not shown - and also to drive the pump device 13 of the liquid dispensing device 4.
- the oscillating member 52 - which is fastened, for example, on wall elements 51 of the housing 1 of the dry shaving apparatus TR - is above a double-arm rocker arm 54, which is pivotably mounted on a pivot axis 53 provided on the housing 1, coupled to a pump element of the pump device 13 for the purpose of transmitting a drive movement.
- This drive connection can be interrupted by moving the liquid container 5 in the arrow direction P2 by the distance A, so that no liquid is transported from the container 5 into the rinsing chamber 214 and the open-pore contact element 22.
- By moving the liquid container 5 in the direction of arrow P1 the contact of the pump element of the pumping device 13 with the double-armed lever 54 can be restored, so that when the electric motor 50 is started up, the oscillating movements of the oscillating element 52 are transmitted to the pumping element of the pumping device 13 via the double-armed lever 54 and restart the liquid transport system.
- the rinsing chamber 214 is coupled to the liquid container 5 by means of a first liquid line line 31 - see FIG. 9 - and to the first chamber 40 via a second liquid line 32.
- the first and second liquid lines are flexible.
- the pump device 13 shows the components of a pumping device 13.
- the pump device 13 consists of only three parts, namely a first housing part 60, a second housing part 61 and a membrane 62 which is provided between the first housing part 60 and the second housing part 61.
- the membrane 62 has a flexible pump element 63, which protrudes slightly arched from the flat membrane wall.
- two flap valves 64 and 65 acting as a check valve are provided in the membrane wall of the membrane 62.
- the flutter valves 64 and 65 are part of the membrane 62 and are flexibly molded into the membrane wall.
- the second housing part 61 has an opening
- a first liquid line 31 can be connected to the second housing part 61.
- a pump chamber 67 which has a flow channel 70 with a first valve chamber
- the second valve chamber 69 can be coupled via an outlet PA and a pump outlet line 75 to a liquid line 47 leading to the first chamber 40 of the liquid container 5 - see FIG. 7 -.
- the flap valve 65 provided in the membrane 62 is assigned on the one hand to the first liquid line 31 and on the other hand to the first valve chamber 68.
- the flutter valve 64 is assigned to the second valve chamber 69 and to the liquid line 47 emanating from it.
- the tensioned elastic pump element 63 moves back to its starting position in the direction of arrow P2 and thereby sucks in air and / or liquid from the first liquid line 31. Due to this suction process, the flutter valve 65 moves into the first valve chamber 68 and thus releases the liquid line 31, so that the air and / or liquid can flow into the pump chamber 67 via the first valve chamber and the flow channel 70.
- the flap valve 64 is designed and arranged to the flow channel 71 that during the suction process, the flow channel 70 is covered to such an extent that no air and / or liquid past the flap valve 64 into the second valve chamber 69 and from this into that of the flap valve 64 uncovered opening of the outlet PA and the pump outlet line 75 can flow.
- the pump device 13 shown in FIG. 10 can - as shown in FIGS. 7 and 8 - be arranged both outside and inside a liquid container 5.
- the pump device 13 can also be designed as a component of the liquid container 5, as shown in FIG. 11, for example.
- the pump device according to FIG. 11 differs from the pump device according to FIG. 10 only in that the first housing part 60 of the pump device 13 is part of a wall of the liquid container 5.
- FIG. 11 shows a part of the interior of a liquid container 5, namely the first chamber 40 by means of a broken line.
- the chamber 40 can be connected to the second liquid line - see FIG. 7 - via a pump outlet line 75.
- a recess 81 is provided in the front 80 of the liquid container 5, in which the first valve chamber 68, the flow channel 70, the pump chamber 67, the flow channel 71 and a liquid line 85, which connects the second valve chamber 69 to the first chamber 40 of the liquid container 5 , intended.
- the membrane 62 is inserted into the recess 81 and by means of the second housing part 61 and corresponding fastening elements, these components are assembled into a complete pump device 13 and then put into operation.
- the liquid container 5 is inserted into the housing 1 of the hair removal device and the sealing part is pierced in the line areas and thus connected to the liquid transport system of the device 1.
- the pump device 13 is positioned in front of the rocking element 54 located in the housing 1.
- the pump device 13 begins to build up pressure in the liquid container 5.
- the air sucked in in the starting phase is pumped into the first chamber 40 and can pass through the outlet gap 43 between the second liquid line 32 and the partition wall 42 into the second chamber 41, to put pressure on the liquid there.
- the suction process of the pump device 13 creates a suction effect in the second liquid line 32 of the liquid circuit, which draws the liquid into the liquid dispensing device 4.
- the application position in the liquid dispensing device 4 is designed such that the pump device 13 can simultaneously suck in air from the outside in addition to the non-applied liquid.
- the pump device 13 After the start phase, the pump device 13 always pumps a liquid-air mixture into the liquid container 5, where it is separated into its two components. The separation takes place through the adhesive force of the liquid droplets on the inner wall of the first chamber 40. The larger drops then flow back through the outlet gap 43 into the second chamber 41 and are thus added to the liquid circuit again.
- the porous storage material also ensures that the function works even when the liquid container 5 is not full. In this case, the capillary action of the storage material causes the liquid to reach the suction area of the second liquid line 32. In addition, the liquid movements and the associated noise are minimized.
- the structure described makes it possible to store and dispense liquids regardless of their position and movement, the system simultaneously regulating the quantity of liquids to be dispensed.
