Abstract

Die Erfindung bezieht sich auf ein kleines Haushalts­ vibrationsgerät zum Abschneiden von Körperhaaren, insbesondere ein Trockenrasiergerät, mit einem von einer elektrischen Antriebsvorrichtung längsbewegbaren Unter­ messer (20), das in Berührung mit einem feststehenden Obermesser (20a) Vibrationsbewegungen ausführt, wobei das Obermesser (20a) mit Haardurchtrittsöffnungen versehen ist und wobei die Antriebsvorrichtung eine mittels Spulen (6) erregbare Statoranordnung aufweist, die einen zweipolig magnetisierten Permanentmagneten (35) bewegt, der die Bewegungen auf das Untermesser (20) überträgt. Der Permanentmagnet (35) wird bei abgeschalteten Statorspulen (6) im Raum des Statorfeldes mittels Federkräften in eine derartige Ruhelage geführt, daß er bei erregten Stator­ spulen (6) Schwingbewegungen um diese Ruhelage ausführt. Weiterhin ist der Permanentmagnet (35) in der Bewegungs­ richtung des Untermessers (20) hin und her verschieblich geführt. The invention relates to a small household vibration device for cutting off body hair, especially a dry shaver, with one of a electric drive device longitudinally movable sub knife (20) in contact with a fixed Upper knife (20a) performs vibratory movements, the Upper knife (20a) is provided with hair passage openings and wherein the drive device is provided by means of coils (6) excitable stator arrangement having a two-pole magnetized permanent magnet (35) which moves the Transfers movements to the lower knife (20). The Permanent magnet (35) is when the stator coils are switched off (6) in the space of the stator field by means of spring forces such rest position that he with excited stator reel (6) performs oscillating movements around this rest position. Furthermore, the permanent magnet (35) is in motion Direction of the lower knife (20) can be moved back and forth guided.
