Patent

CA 2141569

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.

Brosse à dents électrique dont la brosse enfilable est dotée d'un piston mis en rotation par un arbre moteur se projetant hors de la poignée. Ce piston présente une came de levage qui lui permet d'effectuer un mouvement axial par rapport à l'arbre moteur de la brosse enfilable. Ce mouvement axial entraîne le va-et-vient d'une crémaillère qui provoque la rotation de la touffe de poils de la brosse à dents.
