Patent

CA 2498868

A power operated toothbrush comprises a hollow handle (12) and a head (14) mounted to the handle. A power drive assembly (16, 18, 20) is in the handle operatively connected to a movable section (24) in the head (14) for moving that section. Cleaning elements (30) extend outwardly from the movable section. A bumper (40) is secured to the peripheral side wall (42) of the head (14). The bumper is made of a soft yieldable material to prevent injury to the teeth and gums and to act as a cushion to minimize high intensity vibration and to deaden sound which would result during use of the power operated toothbrush.

L'invention concerne une brosse à dents électrique comprenant un manche creux (12) et une tête (14) montée sur ce manche. Un système d'entraînement (16, 18, 20), intégré dans le manche, est relié fonctionnellement à une section mobile (24) située dans la tête (14), de façon à mettre en mouvement cette section. Des éléments de nettoyage (30) s'étendent vers l'extérieur depuis cette section mobile. Un tampon amortisseur (40) est fixé à la paroi latérale périphérique (42) de la tête (14). Ce tampon amortisseur est constitué d'un matériau souple déformable évitant les blessures aux dents et aux gencives, lequel tampon amortisseur agit comme un coussinet pour minimiser la vibration à haute intensité et atténuer le bruit provoqué au cours de l'utilisation de cette brosse à dents électrique.
