Title
(EN) ELECTRIC TOOTHBRUSH
(FR) BROSSE À DENTS ÉLECTRIQUE
Abstract
(EN)
An electric toothbrush includes a stem member on which a replaceable toothbrush is mounted. The stem member is made of synthetic resin and has a cavity for accommodating a DC motor and a vibration shaft connected to the DC motor. One end of the cavity is opened for inserting the DC motor and the vibration shaft together, and the other end thereof is closed. A free end of the vibration shaft is rotatably supported at the closed end of the cavity. The cavity has a cone-shaped wall so that the DC motor is firmly held in the cavity by a rigid contact between a shoulder portion of the DC motor and the cone-shaped wall.

La présente invention concerne une brosse à dents électrique qui comprend un élément de tige sur lequel une brosse à dents remplaçable est montée. L'élément de tige est constitué de résine synthétique et a une cavité pour loger un moteur C.C. et un arbre de vibration relié au moteur C.C. Une extrémité de la cavité est ouverte pour insérer le moteur C.C. et l'arbre de vibration conjointement, et l'autre extrémité de celui-ci est fermée. Une extrémité libre de l'arbre de vibration est soutenue de manière rotative au niveau de l'extrémité fermée de la cavité. La cavité a une paroi en forme de cône de sorte que le moteur C.C. soit fermement maintenu dans la cavité par un contact rigide entre une partie d'épaulement du moteur C.C. et la paroi en forme de cône.
