ABSTRACT:
An electric toothbrush having in its slip-on brush a piston is disclosed, which is set rotating by a motor shaft projecting out of the handle segment. This piston exhibits a lifting cam, by means of which it effects an axial motion relative to the motor shaft in the slip-on brush. This axial motion causes a reciprocating motion of a toothed rack, which sets the bristle tufts of the toothbrush rotating.
