Abstract

La présente invention concerne une brosse à dents électrique. L'invention concerne pour cela d'une part un manche de brosse à dents comprenant un dispositif de couplage destiné à la fixation d'un embout, en particulier d'une brosse, et une pièce de chaîne de transmission, en particulier un arbre d'entraînement, pouvant être entraînée par un moteur d'entraînement et servant à entraîner l'embout. L'invention concerne d'autre part ledit embout qui peut en particulier être une brosse, comprenant une pièce de raccord qui peut être montée sur le col du manche de la brosse à dents. Le manche de la brosse à dents présente des moyens de blocage qui peuvent être débloqués, lesdits moyens de blocage servant à inhiber, bloquer et/ou freiner la pièce de chaîne de transmission. Les moyens de blocage présentent l'avantage d'être débloqués automatiquement lors de la mise en place d'une brosse et d'être mis dans leur état de blocage actif lors du retrait de la brosse. Lorsque la pièce de chaîne de transmission est bloquée, le moteur d'entraînement est automatiquement mis hors tension.
