Title
(EN) DUAL MOTION POWERED TOOTHBRUSH
(FR) BROSSE À DENTS À MOUVEMENT DOUBLE
Abstract
(EN)
A replaceable brush head for a powered toothbrush and a toothbrush incorporating the same. The brush head includes a body having a bore extending therethrough and a driveshaft extending through the bore and rotatable about a longitudinal axis. A first bristle block is disposed in the body and is operatively engaged with the driveshaft. A second bristle block is disposed in the body and is operatively engaged with the first bristle block. Rotation of the driveshaft produces a first type of motion in the first bristle block and the motion of the first bristle block produces a second type of motion in the second bristle block.
(FR)
La présente invention concerne une tête de brosse remplaçable pour une brosse à dents électrique et une brosse à dents incorporant celle-ci. La tête de brosse comprend un corps ayant un alésage s'étendant à travers celui-ci et une tige de commande s'étendant à travers l'alésage et pouvant tourner autour d'un axe longitudinal. Un premier bloc de poils est disposé dans le corps et est fonctionnellement engagé avec la tige de commande. Un deuxième bloc de poils est disposé dans le corps et est fonctionnellement engagé avec le premier bloc de poils. La rotation de la tige de commande produit un premier type de mouvement dans le premier bloc de poils et le mouvement du premier bloc de poils produit un deuxième type de mouvement dans le deuxième bloc de poils.
