Definitions
- the invention relates to an electrically operated shaver according to the preamble of patent claim 1 and a method for this purpose.
- a razor of the aforementioned type is known in which the fluid located in a liquid tank is transformed by an ultrasonic vibrator to fog, which is then fed via a line to the shaving head receiving space.
- the fine mist passes through the holes formed in the blade to the outside on the skin surface, which not only makes the skin softer, but at the same time a lubricant of the skin is constantly fed in the constant flow during a shaving.
- the advantage facilitates the reciprocating movement of the shaver on the skin, cools the skin, reduces small injuries to the skin and reduces the sliding properties of the moving parts in the shaving head, which ultimately results in an overall improved shaving behavior.
- the object of the invention is therefore to provide a shaving device that cools the skin of an operator with extremely simple means during a shaving process, reduces the sliding properties and at the same time adds conditioning substances, fragrances and softening substances to the skin in order to make a shaving process more pleasant.
- the characterizing features of claim 1 no liquid, but a foam is introduced into the chamber receiving the blade block before shaving. In this case, so much foam is entered into the room until it easily swells or becomes recognizable at the holes of the shaving foil or on the transitions between the shaving foil and the shaving head frame, which form the finest slits.
- the foam is in a pressurized spray bottle from which it is injected into the room.
- the foam in the shaving head also prevents Bartstaub trickling outwards. Foam binds the beard dust, this allows easy cleaning by rinsing the device under running water.
- shaving foil it is also conceivable to remove the shaving foil from the shaving head and to spray the foam around the blade block as well as on the latter itself, so that when the shaving foil is placed on the shaving head frame, the foam is compressed in the resulting space so that the space becomes full filled with foam. Excess foam can then pass outward at the transitions between the shear foil and the shaving head frame as well as over the holes in the shaving foil. Since the shaving foil is usually attached to a removable frame, so the slots can of course also arise between the removable frame and the shaving head, where then the foam penetrates to the outside.
- shaving means may be meant in which the shaving head frame is integrally connected to the drive housing, so that the space receiving the blade block is formed only by the housing of the shaver and the shaving foil.
- the blade block when the electric drive of the shaver is turned on, the blade block is set in reciprocating vibrations by a protruding from the drive housing of the shaver drive shaft.
- the blade block oscillates at a frequency of about 5-10 thousand hertz.
- a piston wall extending transversely to the shearing movement is formed, the lateral surface of which facing the shearing foil follows the contour of the inner surface of the shaving foil and slidably bears against it.
- the lateral surface of the piston wall facing the bottom of the shaving device forms a kind of fixed housing wall with the foam.
- the foam In the first strokes of the piston wall, the foam is initially displaced according to the size of the piston surface and the piston stroke. During further reciprocations, an air-filled displacement forms between the foam, the foil and the piston wall, in which the air is constantly compressed and decompressed. During compression, part of the air is conveyed outward through the holes in the area of the displacement in the foil. When decompressing, ie during the return stroke of the piston wall, air is sucked in through the holes in the displacement.
- a respective piston wall is formed at both ends of the blade block. This creates both at one end and at the other end of the foil a bubble, so that both sides of the foil shear cooling air of the skin of an operator is supplied.
- the piston wall is formed in each case by the last blade of the blade block.
- tubular blade block in which many slots arranged one behind the other are introduced, as is the case in the long-selling by the applicant shavers "Braun Syncro" the case.
- the remaining walls form the individual blades of the blade block.
- blade blocks on which the individual knives are designed as closed sheet metal discs can be used for the invention, because each formed at the end blade forms a piston wall, regardless of whether it is annular or disc-shaped or otherwise formed. It is only important that the section of the form of the shaving foil coming into contact with the shaving foil is adapted and the foam forms a displacement with the shaving foil and the piston.
- the most effective variant of a piston wall is formed when the piston is closed flat and disk-shaped (claim 4).
- an opening forming the shaving head an opening with a channel through which the foam is introduced from outside into the room.
- the channel can be formed anywhere on the housing, he only has to reach into the room. It is beneficial in this case to form the channel on the preferably made of plastic, and receiving the foil receiving the removable frame, since here the channel during spraying of the removable frame can be formed with the same. The channel is so deep that the foam can penetrate from below into the room.
- a sealing surface is formed at the entrance of the channel, on which the connecting piece of the foam dispensing pressure bottle can be placed in register and pressure-tight.
- the foam is made of shaving foam, as commercially available in pressurized bottles.
- This foam has a relatively high stiffness with very finely trapped air bubbles, so that it can form a dimensionally stable capacity. But there are also quite different foams with the above requirements possible.
- the foam is enriched with methanol (claim 8), so that the escaping air from the displacement absorb these fragrances and can deliver to the atmosphere or to the skin surface.
- the foam is also possible to use the foam with mint To enrich (claim 9), because this essential oil has a particularly rich, good fragrant and has proven particularly effective as a fragrance distributor in the air.
- other fragrances can be used in the foam, which are then released from the blown out of the displacement air to the skin or to the atmosphere.
- the shaver 1 consists of a with an electric drive (not shown) provided housing 2, on the right side wall of an on or off switch 3 is formed. At the front there is a slide switch 18, on which at the upper end a transverse beard trimmer 4 is designed as a trimmer. At the bottom, the shaver 1 has an electrical connection 5 for the power supply of the shaver 1.
- a shaving head frame 6 is placed from above, which has raised at its two lateral ends arms 7, 8, which are connected to one another by the beard trimmer 4 for the most part covered bridge 9.
- the Shaving head frame 6 is separable from the housing 2 of the shaver 1 via a parting line 11. Of course, it is also conceivable that the shaving head frame 6 is connected with its arms 7, 8 and its bridge 9 in one piece with the housing 2 of the shaver 1.
- the shaving head frame 6 is after Fig. 1 via the parting line 11 of the housing 2 can be removed upwards.
- a shearing foil 12 with a replaceable frame 13 carrying the shaving foil 12 is inserted from above and detachably fixed there by latching means (not shown).
- the foil 12 consists in this embodiment of two upwardly curved Scherfolienabêten 14, 15 which are provided with many small holes 16.
- sheet metal areas are formed, which have no holes 16, because there is the skin surface hardly touch and on the other hand thereby formed a closed area of the foil without holes is, so that foam and air do not leak on the side but above.
- a channel 19 is formed according to the FIGS. 2 and 3 into a space 24 formed by the inner surface 20 of the shear foil 12, the left and right side surface 21, 22 and the bottom surface 23 of the shaving head frame 6.
- a sealing surface 25 is still formed on the channel 19, which serves for the pressure-tight attachment of a foam bottle (not shown) formed connecting piece (not shown).
- FIG. 2 From the bottom surface 23 penetrates FIG. 2 from the housing 2 upwards a drive rod 26 out, which is articulated via a coupling member 27 with a blade block 28, but in the reciprocating motion Y of the blade block 28 fixed thereto.
- the blade block 28 is releasable via the coupling member 27 from the drive rod 26 for the purpose of cleaning or for the purpose of replacement.
- the blade block 28 is after FIG. 2 provided with a carrier 29, on which many individual successively arranged blades 30 are formed.
- the blades are perpendicular to the inner surface 20 of the shear foil 12 and are adapted to the inner surface 20 at least in the region of the holes 16.
- a carrier 29 on which many individual successively arranged blades 30 are formed.
- the blades are perpendicular to the inner surface 20 of the shear foil 12 and are adapted to the inner surface 20 at least in the region of the holes 16.
- the shaving foil 12 consists of two shear foil sections 14, 15 formed parallel to one another, of course two blade blocks 28 arranged next to one another (the second one behind them can not be seen) are fastened to the coupling member 27.
- the blades 35, 36 formed at the ends of the blade block 28 form the respective piston wall according to the invention.
- the blades 30 were made of a metallic tube in which 30 slots 37 was sawed into the tube to form the blades, resulting as a piston wall 35, 36 an annular surface, but this is not apparent in the drawing.
- the foam bottle (not shown) is closed again and can remove its connecting piece from the sealing surface 25 of the channel 19.
- the device can be turned on via the on / off switch 3, in which case the blade block 28 according to the FIGS. 2 and 3 horizontally in the direction of Y reciprocated.
- the blade block 28 moves according to the FIGS. 2 and 3 to the right, the piston wall 38 shifts the foam 39 to the right, which is then distributed in the space 24, or partially still emerges from the holes 16 of the shear foil 12 and from the slots 40.
- the foam 39 separates from the piston wall 38 and remains substantially as a foam wall 43 at the height of the maximum stroke. Now, on the left side of the same process, as described above, so that it is not repeated at this point.
- the object of the invention can be realized almost without additional means, because only a channel 19 and foam is needed.
- the formation of the piston wall 38 is not an expense, since it is present anyway and formed only as a closed surface should be to make optimal air cushion 45, 46.
- the foam 39 should have a consistency similar to a shaving cream, with the air bubbles in the foam 39 being so small as to provide sufficient resistance of the air during the compression process.
- the foam 39 which nevertheless exits the holes 16 of the sheeting 12 can smooth the surface of the skin and give it a pleasant odor, if the foam contains 39 fragrant substances.
- the foam 39 may further develop the benefits otherwise associated with wet shaving.

Die Erfindung betrifft ein elektrisch betriebenes Rasiergerät gemäß dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren hierzu.The invention relates to an electrically operated shaver according to the preamble of patent claim 1 and a method for this purpose.

Aus der
Alle oben genannten Rasiergeräte haben allerdings den Nachteil, daß zur Verteilung der Flüssigkeit aufwändige Fördereinrichtungen und Tanks im Rasiergerät erforderlich sind, was neben dem erheblich größeren konstruktiven und produktiven Aufwand auch zu kostspieligen Rasiergeräten führt.However, all the above-mentioned shavers have the disadvantage that the distribution of liquid consuming conveyors and tanks are required in the shaver, which leads to costly shaving equipment in addition to the significantly greater design and production costs.
Aufgabe der Erfindung ist es nun, ein Rasiergerät zu schaffen, das mit äußerst einfachen Mitteln während eines Rasiervorgangs die Haut einer Bedienungsperson kühlt, die Gleiteigenschaften reduziert und gleichzeitig Pflegestoffe zur Konditionierung, Duft- und Weichmacherstoffe der Haut zuführt, um einen Rasiervorgang angenehmer zu gestalten.The object of the invention is therefore to provide a shaving device that cools the skin of an operator with extremely simple means during a shaving process, reduces the sliding properties and at the same time adds conditioning substances, fragrances and softening substances to the skin in order to make a shaving process more pleasant.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Gemäß der Erfindung wird nun vor einem Rasiervorgang keine Flüssigkeit, sondern ein Schaum in den den Klingenblock aufnehmenden Raum eingebracht. Dabei wird in den Raum soviel Schaum eingegeben, bis er an den Löchern der Scherfolie bzw. an den zwischen der Scherfolie und dem Scherkopfrahmen ausgebildeten Übergängen, die feinste Schlitze darstellen, leicht herausquillt bzw. dort erkennbar wird. Vorzugsweise befindet sich der Schaum in einer unter Druck stehenden Sprühflasche, aus der dieser in den Raum eingespritzt wird. Der Schaum im Scherkopf verhindert auch, daß Bartstaub nach außen rieselt. Schaum bindet den Bartstaub, dies ermöglicht eine einfache Reinigung durch Ausspülen des Gerätes unter fließendem Wasser.This object is achieved by the characterizing features of claim 1. According to the invention, no liquid, but a foam is introduced into the chamber receiving the blade block before shaving. In this case, so much foam is entered into the room until it easily swells or becomes recognizable at the holes of the shaving foil or on the transitions between the shaving foil and the shaving head frame, which form the finest slits. Preferably, the foam is in a pressurized spray bottle from which it is injected into the room. The foam in the shaving head also prevents Bartstaub trickling outwards. Foam binds the beard dust, this allows easy cleaning by rinsing the device under running water.
Es ist aber auch denkbar, die Scherfolie vom Scherkopf abzunehmen und den Schaum rund um den Klingenblock herum sowie auf diesen selbst zu sprühen, so daß beim Aufsetzen der Scherfolie auf den Scherkopfrahmen der Schaum derart in den dann entstehenden Raum komprimiert wird, daß der Raum voll mit Schaum angefüllt ist. Dabei kann dann überschüssiger Schaum an den Übergängen von Scherfolie und Scherkopfrahmen sowie über die Löcher der Scherfolie nach außen treten. Da die Scherfolie meistens an einem Wechselrahmen befestigt ist, so können die Schlitze selbstverständlich auch zwischen dem Wechselrahmen und dem Scherkopf entstehen, wo dann der Schaum nach außen dringt. Selbstverständlich können auch im Sinne der Erfindungen Rasiergeräte gemeint sein, bei denen der Scherkopfrahmen einteilig mit dem Antriebsgehäuse verbunden ist, so daß der den Klingenblock aufnehmende Raum lediglich vom Gehäuse des Rasiergerätes und der Scherfolie gebildet wird.However, it is also conceivable to remove the shaving foil from the shaving head and to spray the foam around the blade block as well as on the latter itself, so that when the shaving foil is placed on the shaving head frame, the foam is compressed in the resulting space so that the space becomes full filled with foam. Excess foam can then pass outward at the transitions between the shear foil and the shaving head frame as well as over the holes in the shaving foil. Since the shaving foil is usually attached to a removable frame, so the slots can of course also arise between the removable frame and the shaving head, where then the foam penetrates to the outside. Of course, in the sense of the inventions shaving means may be meant in which the shaving head frame is integrally connected to the drive housing, so that the space receiving the blade block is formed only by the housing of the shaver and the shaving foil.
Wird nun der elektrische Antrieb des Rasiergerätes eingeschaltet, so wird der Klingenblock durch einen aus dem Antriebsgehäuse des Rasiergerätes herausragenden Antriebsschaft in hin- und hergehende Schwingungen versetzt. Der Klingenblock schwingt dabei etwa mit einer Frequenz von 5-10 Tausend Hertz. Gemäß der Erfindung ist mindestens an einer Seite am Klingenblock eine quer zur Scherbewegung verlaufende Kolbenwand ausgebildet, deren der Scherfolie zugewandten Mantelfläche der Kontur der Innenfläche der Scherfolie folgt und an dieser gleitend anliegt. Die zum Boden des Rasiergerätes zugewandte Mantelfläche der Kolbenwand bildet mit dem Schaum eine Art feststehende Gehäusewand.Now, when the electric drive of the shaver is turned on, the blade block is set in reciprocating vibrations by a protruding from the drive housing of the shaver drive shaft. The blade block oscillates at a frequency of about 5-10 thousand hertz. According to the invention, at least on one side of the blade block, a piston wall extending transversely to the shearing movement is formed, the lateral surface of which facing the shearing foil follows the contour of the inner surface of the shaving foil and slidably bears against it. The lateral surface of the piston wall facing the bottom of the shaving device forms a kind of fixed housing wall with the foam.
Bei den ersten Hüben der Kolbenwand wird zunächst der Schaum entsprechend der Größe der Kolbenfläche und des Kolbenhubes verdrängt. Bei weiteren Hin- und Herbewegungen bildet sich ein mit Luft gefüllter Hubraum zwischen dem Schaum, der Scherfolie und der Kolbenwand, in dem die Luft ständig komprimiert und dekomprimiert wird. Beim Komprimieren wird ein Teil der Luft über die Löcher, die sich im Bereich des Hubraumes in der Scherfolie befinden, nach außen befördert. Beim Dekomprimieren, also beim Rückhub der Kolbenwand, wird Luft über die Löcher in den Hubraum angesaugt.In the first strokes of the piston wall, the foam is initially displaced according to the size of the piston surface and the piston stroke. During further reciprocations, an air-filled displacement forms between the foam, the foil and the piston wall, in which the air is constantly compressed and decompressed. During compression, part of the air is conveyed outward through the holes in the area of the displacement in the foil. When decompressing, ie during the return stroke of the piston wall, air is sucked in through the holes in the displacement.
Es kann aber auch Luft über feinste Kanäle, die sich beim Rückhub aufgrund des Unterdruckes im Schaum bilden können und die an den Übergängen zwischen der Scherfolie und dem Scherkopf beginnen und zum Hubraum führen, angesaugt werden. Bei den sehr hohen Bewegungsfrequenzen des Klingenblockes ist die durch die Kolbenwand aus dem Hubraum und anschließend über die Löcher ausgeblasene Luftmenge nicht unerheblich, so daß während des Rasiervorganges durch die ausgeblasene Luft eine die Haut kühlende Wirkung entsteht. Da auch anfänglich ein wenig Schaum durch die Löcher ausgetreten sein kann, kann dieser auf die Haut gelangen und reduziert somit die Gleitbewegung und macht die Haut weicher. Der Schaum kann auch Duftstoffe an die Hautoberfläche bzw. an die Atmosphäre abgeben, so daß der Rasiervorgang angenehmer und dabei auch noch verbessert wird. Die Merkmale des Patentanspruchs 1 ergeben somit eine Fördereinrichtung, die außer der Bereitstellung des Schaums keine weiteren technischen Mittel benötigt, so daß auch bei bereits vorhandenen Rasiergeräten die Erfindung angewendet werden kann.But it can also be air through the finest channels that can form during the return stroke due to the negative pressure in the foam and start at the transitions between the shaving foil and the shaving head and lead to the displacement, are sucked. At the very high frequencies of movement of the blade block, the amount of air blown through the piston wall from the displacement and then on the holes is not insignificant, so that during the shaving process by the blown air, the skin cooling effect. Since a little foam may have leaked out of the holes at first, it may get on the skin, reducing the gliding motion and making the skin softer. The foam can also deliver fragrances to the skin surface or to the atmosphere, so that the shaving process is more pleasant and even better. The features of claim 1 thus provide a conveyor that requires no further technical means except the provision of the foam, so that even with existing shavers, the invention can be applied.
Gemäß den Merkmalen des Patentanspruchs 2 ist es vorteilhaft, wenn an beiden Enden des Klingenblocks je eine Kolbenwand ausgebildet ist. Dadurch entsteht sowohl am einen Ende wie am anderen Ende der Scherfolie ein Luftpolster, so daß beidseitig der Scherfolie Kühlluft der Haut einer Bedienungsperson zugeführt wird.According to the features of
Gemäß den Merkmalen des Patentanspruchs 3 wird die Kolbenwand jeweils von der letzten Klinge des Klingenblocks gebildet. Bekanntlich gibt es rohrförmige Klingenblocks, in die viele hintereinander angeordnete Schlitze eingebracht sind, wie dies bei den von der Anmelderin seit langem vertriebenen Rasierern "Braun Syncro" der Fall ist. Dabei bilden die stehengebliebenen Wände die einzelnen Klingen des Klingenblocks. Es gibt aber auch Klingenblocks, an denen die einzelnen Messer als geschlossene Blechscheiben ausgebildet sind. Diese Varianten können für die Erfindung eingesetzt werden, weil jede am Ende ausgebildete Klinge eine Kolbenwand bildet, gleichgültig ob sie ringförmig oder scheibenförmig oder sonst wie ausgebildet ist. Wichtig ist nur, daß der mit der Scherfolie in Berührungskontakt tretende Abschnitt der Form der Scherfolie angepaßt ist und der Schaum mit der Scherfolie und dem Kolben einen Hubraum bildet. Die wirkungsvollste Variante einer Kolbenwand entsteht natürlich, wenn der Kolben flächig geschlossen und dabei scheibenförmig ausgebildet ist (Anspruch 4).According to the features of
Vorteilhaft ist es gemäß den Merkmalen des Anspruchs 5, an einer dem Scherkopf bildenden Seitenwand eine Öffnung mit einem Kanal auszubilden, über den der Schaum von außen in den Raum eingeführt wird. Der Kanal kann an beliebiger Stelle am Gehäuse ausgebildet sein, er muß nur in den Raum hineinreichen. Günstig ist dabei, den Kanal am vorzugsweise aus Kunststoff hergestellten, und die Scherfolie aufnehmenden Wechselrahmen auszubilden, da hier der Kanal beim Spritzen des Wechselrahmens gleich mit ausgeformt werden kann. Dabei ist der Kanal so tief angeordnet, daß der Schaum von unten her in den Raum eindringen kann.It is advantageous according to the features of
Gemäß den Merkmalen des Patentanspruchs 6 ist am Eingang des Kanals eine Dichtfläche ausgebildet, auf die das Anschlußstück der den Schaum abgebenden Druckflasche paßgenau und druckdicht aufgesetzt werden kann.According to the features of
Gemäß den Merkmalen des Patentanspruchs 7 besteht der Schaum aus Rasierschaum, so wie er im Handel in unter Druck stehenden Flaschen erhältlich ist. Dieser Schaum besitzt eine verhältnismäßig hohe Steifigkeit bei sehr fein eingeschlossenen Luftbläschen, so daß dieser einen formstabilen Hubraum bilden kann. Es sind aber auch durchaus andere Schäume mit obigen Anforderungen möglich.According to the features of
Vorteilhaft ist der Schaum mit Methanol (Anspruch 8) angereichert, damit die austretende Luft aus dem Hubraum diese Duftstoffe aufnehmen und an die Atmosphäre bzw. an die Hautoberfläche abgeben kann. Vorteilhafterweise ist es auch möglich, den Schaum mit Minze (Anspruch 9) anzureichern, weil auch dieses ätherische Öl besonderes ergiebig, gut duftend und sich als Duftverteiler in der Luft besonders bewährt hat. Selbstverständlich können auch andere Duftstoffe im Schaum eingesetzt werden, die dann von der aus dem Hubraum ausgeblasenen Luft an die Haut bzw. an die Atmosphäre abgegeben werden.Advantageously, the foam is enriched with methanol (claim 8), so that the escaping air from the displacement absorb these fragrances and can deliver to the atmosphere or to the skin surface. Advantageously, it is also possible to use the foam with mint To enrich (claim 9), because this essential oil has a particularly rich, good fragrant and has proven particularly effective as a fragrance distributor in the air. Of course, other fragrances can be used in the foam, which are then released from the blown out of the displacement air to the skin or to the atmosphere.
Gemäß den Merkmalen des Patentanspruchs 10 wird noch ein Verfahren unter Schutz gestellt, bei dem Schaum in den Raum eingebracht wird. Anschließend wird nach Einschalten des Rasiergerätes durch die Bildung der nach dem Prinzip einer Luftpumpe arbeitenden Pumpe Luft über die Löcher der Scherfolie nach außen abgegeben, die dann als Luftpolster auf der Hautoberfläche einer Bedienungsperson wirkt und gleichzeitig die Gleitreibung auf der Haut verringern kann.According to the features of

Die Wirkung- und Arbeitsweise des erfindungsgemäßen Gerätes ist folgende:
- Vor Einschalten des Rasiergerätes 1 wird an
der Dichtfläche 25 eine unter Druck stehende Schaumflasche mit ihrem Abgabestutzen (nicht dargestellt) angesetzt undSchaum 39über den Kanal 19 inden Raum 24 eingeleitet, und zwar so lange,bis der Schaum 39aus den Löchern 16der Scherfolie 12 austritt. Da der Wechselrahmen 13 keine 100%ige Abdichtung amÜbergang zum Scherkopfrahmen 6 aufweist, kann es auch sein, daß über diesen Spalt, gekennzeichnet durch dieumlaufende Linie 40 auch ein wenig Schaum austritt. Um dies zu vermeiden, könnte man der Linie 40 entlang eine Dichtung (nicht dargestellt) anspritzen, die dann beim Aufsetzen dermit dem Wechselrahmen 13 verbundenen Scherfolie 12 inden Aufnahmeraum 10 einen dichten Abschluß bildet. Demnach könnte dann nur noch Schaum über dieLöcher 16der Scherfolie 12 austreten und anzeigen, wann derRaum 24mit Schaum 39 gefüllt ist.
- Before switching on the shaver 1, a pressurized foam bottle with its discharge nozzle (not shown) attached to the sealing
25 and 39 foam introduced via thesurface channel 19 into thespace 24, and that until thefoam 39 from theholes 16 ofShear foil 12 emerges. Since theremovable frame 13 is not 100% seal has at the transition to theshaving head frame 6, it may also be that on this gap, characterized by thecircumferential line 40 also exits a little foam. To avoid this, one could spray theline 40 along a seal (not shown), which then forms a tight seal when placing theshear foil 12 connected to theremovable frame 13 in the receivingspace 10. Accordingly, then only foam could escape through theholes 16 of thefoil 12 and indicate when thespace 24 is filled withfoam 39.
Sobald dieser Zustand eingetreten ist, verschließt man wieder die Schaumflasche (nicht dargestellt) und kann ihren Anschlußstutzen von der Dichtfläche 25 des Kanals 19 entfernen. Nun kann das Gerät über den Ein-/Aus-Schalter 3 eingeschaltet werden, wobei dann der Klingenblock 28 sich gemäß der
Bei mehrmaligem Hin- und Herbewegen des Klingenblockes 28 entsteht ein verhältnismäßig stabiler Hubraum 41, 42 zu beiden Seiten des Klingenblockes 28, der, da beim Rückhub die Kolbenwand 38 Luft über die Löcher 16 angesaugt hat, mit Luft aufgefüllt ist. Der Hubraum 41 wird also von der einen Seite von der Kolbenwand 38, von oben her von der Innenfläche 20 der Scherfolie 12 und stirnseitig wie von unten her von den Schaumwänden 43, 44 gebildet. Da der Klingenblock 28 etwa mit einer Frequenz von 7000-9000 Hertz hin und her schwingt, wird der Hubraum 41 so schnell zusammengedrückt, daß die Luft über die im Bereich des Hubraumes 41 erstreckenden Löcher 16 nach außen pufft und so ein Luftpolster 45, 46 an der äußeren Mantelfläche der Scherfolie 12 bildet, derart, daß beim Rasieren die Hautoberfläche (nicht dargestellt) einer Bedienungsperson gekühlt wird. Beim Rasiervorgang werden, wie allgemein bekannt, die in die Löcher eintretenden Haare von den Klingen erfaßt, abgeschnitten und im Raum 24 vom Schaum 39 aufgenommen.In repeated reciprocating the
Der Gegenstand der Erfindung läßt sich fast ohne zusätzliche Mittel realisieren, weil lediglich ein Kanal 19 sowie Schaum benötigt wird. Die Ausbildung der Kolbenwand 38 stellt keinen Aufwand dar, da sie ohnehin vorhanden ist und lediglich als geschlossene Fläche ausgebildet sein sollte, um optimale Luftpolster 45, 46 zu bilden. Der Schaum 39 sollte eine Konsistenz ähnlich einem Rasierschaum haben, wobei die im Schaum 39 befindlichen Luftblasen so klein sind, daß sie ausreichend Widerstand der Luft beim Kompressionsvorgang leisten.The object of the invention can be realized almost without additional means, because only a
Durch das Luftpolster 45, 46 wird nicht nur die Haut gekühlt, sondern die Reibwerte zwischen der Scherfolie 12 und der Hautoberfläche können reduziert werden. Der dennoch aus den Löchern 16 der Scherfolien 12 austretende Schaum 39kann die Hautoberfläche glätten und ihr einen angenehmen Duft verleihen, wenn im Schaum 39 gut duftende Stoffe enthalten sind.
