Durch diese Öffnung ist eine zweite Flüssigkeitsleitung 32 hindurchgeführt, die in einem vorgegebenen Abstand B zum Boden 46 des Flüssigkeitsbehälters 5 endet. Die Größe der Öffnung in der Trennwand 42 ist deart bemessen, daß nach Durchführung der zweiten Flüssigkeitsleitung 32 ein Spalt 43 gebildet ist. Dieser Spalt dient zur Zuführung von Flüssigkeit aus der ersten Kammer 40 in die zweite Kammer 41. In der zweiten Kammer 41 ist ein poröses Speichermaterial 44 - z.B. gesinterter Werkstoff - zur Speicherung von Flüssigkeit vorgesehen. Die erste Kammer 40 ist über eine Flüssigkeitsleitung 47 mit einer außerhalb des Flüssigkeitsbehälters 5 vorgesehenen Pumpvorrichtung 13 verbunden. Mittels eines Überdruckventils 45 ist im Betriebzustand des Flüssigkeitstransportsystems der erforderliche Druck zum Fördern von Flüssigkeit aus der zweiten Kammer 41 über die als Steigrohr wirkende zweite Flüssigkeitsleitung 32 in die Flüssigkeitsabgabevorrichtung 4 herstellbar. Das Überdruckventil 45 kann beispielsweise aus einem Rohr bestehen, mit einer Öffnung deren Querschnitt derart bemessen ist, daß der erforderliche atmophärische Druck zur Förderung der Flüssigkeit nach Inbetriebnahme der Pumpvorrichtung 13 erreichbar und ein darüber hinaus gehender Überdruck ablaßbar ist.Fig. 7 shows a schematic representation of a liquid transport system from the liquid container 5 to the liquid dispenser 4 and the liquid dispenser 4 back into the liquid container 5. In the liquid container 5 is a Partition wall 42 for forming a first chamber 40 and a second chamber 41 is provided. In the partition wall 42 an opening is provided. Through this opening is a second Liquid line 32 passed, which at a predetermined distance B to the bottom 46th of the liquid container 5 ends. The size of the opening in the partition 42 is deart dimensioned that after performing the second liquid line 32, a gap 43 is formed is. This gap serves to supply liquid from the first chamber 40 into the second Chamber 41. In the second chamber 41 is a porous storage material 44 - e.g. sintered Material - intended for storage of liquid. The first chamber 40 is over a Liquid line 47 with a provided outside of the liquid container 5 pumping device 13 connected. By means of a pressure relief valve 45 is in the operating state of the liquid transport system the pressure required to deliver fluid from the second Chamber 41 via acting as a riser second liquid line 32 into the liquid dispensing device 4 producible. The pressure relief valve 45 may for example consist of a Tube consist, with an opening whose cross-section is dimensioned such that the required atmophärische pressure to convey the liquid after commissioning of the pumping device 13 achievable and beyond going over pressure can be discharged.

Im Gehäuse 1 des Trockenrasierapparates TR ist ein Elektromotor 50 angeordnet, dessen Motorwelle über einen Exzenter mit einem Schwingelement 52 gekoppelt ist, um dieses in hin und hergehende Schwingbewegungen - siehe Pfeilrichtung S1 und S2 - zu versetzen. Die Schwingbrücke 52 dient zum Antrieb von Schneidelementen des Trockenrasierapparates TR - nicht dargestellt - und darüber hinaus zum Antrieb der Pumpvorrichtung 13 der Flüssigkeitsabgabevorrichtung 4. Zu diesem Zweck ist das Schwingelement 52 - das beispielsweise auf Wandelementen 51 des Gehäuses 1 des Trockenrasierapparates TR befestigt ist - über einen doppelarmigen Schwinghebel 54, der auf einer am Gehäuse 1 vorgesehenen Schwenkachse 53 schwenkbar gelagert ist, mit einem Pumpelement der Pumpvorrichtung 13 zum Zwecke der Übertragung einer Antriebsbewegung gekoppelt. Diese Antriebsverbindung kann durch Verschiebung des Flüssigkeitsbehälters 5 in Pfeilrichtung P2 um den Abstand A unterbrochen werden, so daß keine Flüssigkeit aus dem Behälter 5 in die Spülkammer 214 und das offenporige Kontaktelement 22 transportiert wird. Mittels Verschiebung des Flüssigkeitsbehälters 5 in Pfeilrichtung P1 ist der Kontakt des Pumpelementes der Pumpvorrichtung 13 mit dem doppelarmigen Hebel 54 wieder herstellbar, so daß bei Inbetriebnahme des Elektromotors 50 die Schwingbewegungen des Schwingelementes 52 über den doppelarmigen Hebel 54 auf das Pumpelement der Pumpvorrichtung 13 übertragen werden und das Flüssigkeitstransportsystem wieder in Betrieb setzen.In the housing 1 of the dry shaver TR, an electric motor 50 is arranged, whose Motor shaft is coupled via an eccentric with a vibrating element 52 to this in reciprocating oscillations - see arrow S1 and S2 - to move. The swing bridge 52 serves to drive cutting elements of the dry shaver TR - not shown - and beyond to drive the pumping device 13 of the Liquid dispensing device 4. For this purpose, the vibrating element 52 - for example mounted on wall elements 51 of the housing 1 of the dry shaver TR is - via a double-armed rocker arm 54 which provided on a housing 1 Pivot axis 53 is pivotally mounted, with a pumping element of the pumping device 13 coupled for the purpose of transmitting a drive movement. This drive connection can by displacement of the liquid container 5 in the direction of arrow P2 be interrupted by the distance A, so that no liquid from the container 5 in the Rinsing chamber 214 and the open-pore contact element 22 is transported. By means of displacement of the liquid container 5 in the direction of arrow P1 is the contact of the pumping element the pumping device 13 with the double-armed lever 54 restored, so that at Commissioning of the electric motor 50, the oscillatory movements of the vibrating element 52nd transmitted via the double-armed lever 54 to the pumping element of the pumping device 13 and restart the fluid transport system.

Die Spülkammer 214 ist mittels einer ersten Flüssigkeitsleitungleitung 31 - siehe Fig. 9 - über die Pumpvorrichtung 13 mit dem Flüssigkeitsbehälter 5 und über eine zweite Flüssigkeitsleitung 32 mit der ersten Kammer 40 gekoppelt. Um der Verschiebung des Flüssigkeitsbehälters 5 in den Pfeilrichtungen P1 und P2 folgen zu können, sind die ersten und zweite Flüssigkeitsleitung flexibel ausgebildet.The rinsing chamber 214 is via a first fluid line 31 - see Fig. 9 - over the pumping device 13 with the liquid container 5 and a second liquid line 32 coupled to the first chamber 40.

In Fig. 10 sind die Bauelemente einer Pumpvorrichtung 13 dargestellt. Die Pumpvorrichtung 13 besteht lediglich aus drei Teilen, und zwar einem ersten Gehäuseteil 60, einem zweiten Gehäuseteil 61 sowie einer Membrane 62, die zwischen dem ersten Gehäuseteil 60 und dem zweiten Gehäuseteil 61 vorgesehen wird. Die Membran 62 weist ein flexibles Pumpelement 63 auf, das leicht gewölbt aus der ebenflächigen Membranwand hervorsteht. In der Membranwand der Membrane 62 sind zwei als Rückschlagventil wirkende Flatterventile 64 und 65 vorgesehen. Die Flatterventile 64 und 65 sind Bestandteil der Membrane 62 und in die Membranwand flexibel eingeformt. Das zweite Gehäuseteil 61 ist mit einer Öffnungs 66 versehen, durch die das Pumpelement 63 von einem Antriebselement - z.B. eines Hebelarmes eines doppelarmigen Hebels 54 nach Fig. 9 - betätigbar ist. An dem zweiten Gehäuseteil 61 ist eine erste Flüssigkeitsleitung 31 anschließbar. In dem ersten Gehäuseteil 60 ist eine Pumpenkammer 67, die über einen Strömungskanal 70 mit einer ersten Ventilkammer 68 und über einen weiteren Strömungskanal 71 mit der zweiten Ventilkammer 69, die in dem zweiten Gehäuseteil 61 vorgesehen ist, verbindbar. Die zweite Ventilkammer 69 ist über einen Auslaß PA und eine Pumpenauslaßleitung 75 an eine zur ersten Kammer 40 des Flüssigkeitsbehälters 5 führende Flüssigkeitsleitung 47 ankoppelbar - siehe Fig. 7 -. Das in der Membrane 62 vorgesehene Flatterventil 65 ist einerseits der ersten Flüssigkeitsleitung 31 und andererseits der ersten Ventilkammer 68 zugeordnet. Das Flatterventil 64 ist der zweiten Ventilkammer 69 sowie der von dieser ausgehenden Flüssigkeitsleitung 47 zugeordnet. Durch Ausübung einer hin und hergehenden Pumpbewegung auf das Pumpelement 63 wird von dem Pumpelement 63 wechselweise ein Ansaugvorgang und ein Pumpvorgang von Flüssigkeit und/oder Luft ausgelöst. Beim Pumpvorgang wird das Pumpelement 63 in Pfeilrichtung P1 in die Pumpenkammer 67 gedrückt. Dabei wird die in der Pumpenkammer 67 vorhandene Flüssigkeit und/oder Luft über den Strömungskanal 71 gegen das Flatterventil 64 gedrückt, bewegt das flexible Flatterventil 64 in die zweite Ventilkammer 69 hinein,wodurch der Strömungsweg der Flüssigkeit und/oder Luft über die zweite Ventilkammer 69 in die Pumpenauslaßleitung 75 freigegeben wird. Die Flüssigkeit und/oder Luft fließt danach über eine anschließbare Flüssigkeitsleitung 47 in die erste Kammer 40 des Flüssigkeitsbehälters. Während dieses Pumpvorganges wirkt die unter Pumpendruck stehende Luft und/oder Flüssigkeit über den Strömungskanal 70 und die erste Ventilkammer 68 auf das Flatterventil 65 ein und schließt die Pumpeneinlaßöffnung im zweiten Gehäuseteil 61 ein, die mit der ersten Flüssigkeitsleitung 31 koppelbar ist.In Fig. 10, the components of a pumping device 13 are shown. The pumping device 13 consists only of three parts, namely a first housing part 60, a second Housing part 61 and a diaphragm 62, between the first housing part 60 and the second housing part 61 is provided. The membrane 62 has a flexible pumping element 63, which protrudes slightly curved from the planar membrane wall. In the diaphragm wall of the diaphragm 62 are two flutter valves acting as a check valve 64 and 65 are provided. The flutter valves 64 and 65 are part of the membrane 62 and molded flexibly into the membrane wall. The second housing part 61 is provided with an opening 66, by which the pumping element 63 is driven by a drive element - e.g. a lever arm a double-armed lever 54 of FIG. 9 - can be actuated. On the second housing part 61, a first liquid line 31 can be connected. In the first housing part 60 is a pump chamber 67, which via a flow channel 70 with a first valve chamber 68 and via a further flow channel 71 with the second valve chamber 69, which in the second housing part 61 is provided connectable. The second valve chamber 69 is over an outlet PA and a pump outlet line 75 to a first chamber 40 of the Liquid container 5 leading liquid line 47 can be coupled - see Fig. 7 -. This in the membrane 62 provided flutter valve 65 is on the one hand the first liquid line 31 and on the other hand associated with the first valve chamber 68. The flutter valve 64 is the second valve chamber 69 and the outgoing from this liquid line 47 assigned. By applying a reciprocating pumping motion to the pumping element 63 is alternately a suction process and a pumping operation of the pumping element 63 triggered by liquid and / or air. During pumping, the pumping element 63 is in Arrow direction P1 is pressed into the pump chamber 67. It will be in the pump chamber 67 existing liquid and / or air via the flow channel 71 against the flutter valve 64, the flexible flapper valve 64 moves into the second valve chamber 69, thereby the flow path of the liquid and / or air via the second valve chamber 69 is released into the pump outlet 75. The liquid and / or air will flow thereafter via a connectable liquid line 47 into the first chamber 40 of the liquid container. During this pumping process, the air under pump pressure acts and / or liquid via the flow channel 70 and the first valve chamber 68 on the Flutter valve 65 and includes the pump inlet opening in the second housing part 61, the can be coupled with the first fluid line 31.

Nach Abschluß des Pumpvorganges bewegt sich das gespannte elastische Pumpelement 63 in Pfeilrichtung P2 in seine Ausgangsstellung zurück und saugt dabei Luft und/oder Flüssigkeit aus der ersten Flüssigkeitsleitung 31 an. Bedingt durch diesen Ansaugvorgang bewegt sich das Flatterventil 65 in die erste Ventilkammer 68 und gibt somit die Flüssigkeitsleitung 31 frei, so daß die Luft und/oder Flüssigkeit über die erste Ventilkammer und den Strömungskanal 70 in die Pumpenkammer 67 einströmen kann. Das Flatterventil 64 ist derart ausgebildet und zum Strömungskanal 71 angeordnet, daß während des Ansaugvorganges der Strömungskanal 70 in einem derartigen Umfang bedeckt wird, daß keine Luft und/oder Flüssigkeit an dem Flatterventil 64 vorbei in die zweite Ventilkammer 69 und von dieser in die vom Flatterventil 64 nicht bedeckte Öffnung des Auslasses PA sowie der Pumpenauslaßleitung 75 strömen kann.After completion of the pumping operation, the tensioned elastic pumping element moves 63 in the direction of arrow P2 back to its initial position and sucks air and / or liquid from the first liquid line 31. Due to this suction moved the flutter valve 65 into the first valve chamber 68 and thus gives the liquid line 31 free, so that the air and / or liquid on the first valve chamber and the Flow channel 70 can flow into the pump chamber 67. The flutter valve 64 is such formed and arranged to the flow channel 71 that during the intake the flow channel 70 is covered to such an extent that no air and / or liquid past the flutter valve 64 into the second valve chamber 69 and from this in the non-covered by the flutter valve 64 opening of the outlet PA and the pump outlet 75 can flow.

Die Membrane 62 wird in die Vertiefung 81 eingelegt und mittels des zweiten Gehäuseteils 61 und entsprechender Befestigungselemente werden diese Bauelemente zu einer kompletten Pumpvorrichtung 13 zusammengebaut und danach in Betrieb genommen.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 pumping device 13 is part of a Wall of the liquid container 5 is. In Fig. 11 is a part of the interior of a liquid container 5 and that the first chamber 40 by a line having interruption shown. The chamber 40 is connected via a pump outlet 75 to the second Liquid line - see Fig. 7 - connectable. In the front 80 of the liquid container 5, a recess 81 is provided, in which the first valve chamber 68, the flow channel 70, the pump chamber 67, the flow channel 71 and a liquid line 85, the second valve chamber 69 with the first chamber 40 of the liquid container 5 connects, provided. The membrane 62 is inserted into the recess 81 and by means of of the second housing part 61 and corresponding fastening elements, these components assembled into a complete pumping device 13 and then in operation taken.

Der Flüssigkeitsbehälter 5 wird in das Gehäuse 1 des Haarentfernungsgerätes eingesetzt und das Dichtungsteil in den Leitungsbereichen durchstochen und somit an das Flüssigkeitstransportsystem des Gerätes 1 angeschlossen. Gleichzeitig wird durch das Einsetzen des Flüssigkeitsbehälters 5 die Pumpvorrichtung 13 vor dem im Gehäuse 1 befindlichen Schwingelement 54 positioniert. Beim Zuschalten der Applikationsfunktion beginnt die Pumpvorrichtung 13 mit dem Druckaufbau in den Flüssigkeitsbehälter 5. Die in der Startphase angesaugte Luft wird in die erste Kammer 40 gepumpt und kann durch den Ablaufspalt 43 zwischen der zweiten Flüssigkeitsleitung 32 und Trennwand 42 in die zweite Kammer 41 gelangen, um dort Druck auf die Flüssigkeit auszuüben. Gleichzeitig entsteht durch den Ansaugvorgang der Pumpvorrichtung 13 in der zweiten Flüssigkeitsleitung 32 des Flüssigkeitskreislaufes eine Sogwirkung, welche die Flüssigkeit in die Flüssigkeitsabgabevorrichtung 4 saugt. Die Applikationsstelle in der Flüssigkeitsabgabevorrichtung 4 ist so ausgelegt, daß die Pumpvorrichtung 13 neben der nicht applizierten Flüssigkeit gleichzeitig Luft von außen ansaugen kann. So wird nach der Startphase von der Pumpvorrichtung 13 immer ein Flüssigkeitsluftgemisch in den Flüssigkeitsbehälter 5 gefördert und dort in seine zwei Komponenten getrennt. Die Trennung geschieht durch die Adhäsionskraft der Flüssigkeitströpfchen an der Innenwand der ersten Kammer 40. Die größer werdenden Tropfen fließen dann durch den Ablaufspalt 43 zurück in die zweite Kammer 41 und werden so dem Flüssigkeitskreislauf wieder zugefügt. The liquid container 5 is inserted into the housing 1 of the hair removal apparatus and piercing the seal member in the lead areas and thus to the liquid transport system connected to the device 1. At the same time, by inserting of the liquid container 5, the pumping device 13 located in front of the housing 1 Oscillating element 54 is positioned. When the application function is activated, the Pumping device 13 with the pressure build-up in the liquid container 5. The in the starting phase sucked air is pumped into the first chamber 40 and can through the drain gap 43 between the second fluid line 32 and partition wall 42 in the second chamber 41st reach there to exert pressure on the liquid. At the same time created by the suction process the pumping device 13 in the second fluid line 32 of the fluid circuit a suction effect, which the liquid in the liquid dispensing device 4th sucks. The application site in the liquid dispenser 4 is designed so that the Pumping device 13 in addition to the non-applied liquid simultaneously suck in air from the outside can. Thus, after the starting phase of the pumping device 13 is always a liquid air mixture conveyed into the liquid container 5 and there in its two components separated. The separation is done by the adhesion of the liquid droplets to the Inner wall of the first chamber 40. The growing drops then flow through the Outflow gap 43 back into the second chamber 41 and so the fluid circuit added again.

Da das System neben der nicht verbrauchten Flüssigkeit permanent Luft ansaugt, wird ein höherer Druck in der ersten Kammer 40 aufgebaut, als der durch die Flüssigkeit entweichende. Dieser Überdruck in der ersten Kammer 40 verhindert ein Zurücklaufen der Flüssigkeit von der zweiten Kammer 41 in die erste Kammer 40. Stabilisiert wird der Druck durch eine definierte Öffnung, in der als Überdruckventil wirkenden Abluftdrossel. Die Anordnung der Abluftdrossel im oberen Bereich der ersten Trennkammer 40 verhindert ein ungewolltes Abblasen der einströmenden Tröpfchen bei Schräglage des Haarentfernungsgerätes. So ist eine Funktion des Systems selbst bei einem zum Beispiel gegenüber der Darstellung nach Fig. 1 um 180° geschwenkten Stellung des Haarentfernungsgerätes gewährleistet.As the system constantly sucks in air next to the unused liquid, it will turn on higher pressure in the first chamber 40 constructed as the escaping through the liquid. This overpressure in the first chamber 40 prevents backflow of the liquid from the second chamber 41 into the first chamber 40. The pressure is stabilized by a defined opening, in which acting as a pressure relief valve exhaust throttle. The order the exhaust throttle in the upper region of the first separation chamber 40 prevents accidental blowing off of the inflowing droplets in the inclined position of the hair removal device. So is a function of the system itself, for example, as compared to the illustration Fig. 1 pivoted by 180 ° position of the hair removal device guaranteed.

Das poröse Speichermaterial sorgt zudem dafür, daß die Funkton auch bei nicht vollem Flüssigkeitsbehälter 5 funktioniert. In diesem Fall gelangt die Flüssigkeit durch die Kapillarwirkung des Speichermaterials zum Ansaugbereich der zweiten Flüssigkeitsleitung 32. Zusätzlich werden die Flüssigkeitsbewegungen und die damit verbundenen Geräusche minimiert.The porous storage material also ensures that the functon even when not full Liquid container 5 works. In this case, the liquid passes through the capillary action of the storage material to the suction region of the second liquid line 32. In addition The fluid movements and the associated noise are minimized.

Durch den beschriebenen Aufbau ist es möglich, Lage und bewegungsunabhängig Flüssigkeiten zu speichern und abzugeben, wobei das System gleichzeitig eine Regelung der abzugebenden Flüssigkeitsmenge vornimmt.Due to the described structure, it is possible to position and motion-independent liquids to store and submit, the system at the same time a regulation of the deliverable Amount of liquid makes.
