Abstract

L'invention concerne une brosse à dents électrique, comprenant : un boîtier (1), un élément d'entraînement (2), une tête (3) de brosse et une tige de support (4). Un corps principal d'entraînement (201) est disposé à l'intérieur du boîtier (1) par l'intermédiaire de la tige de support (4) et peut tourner par rapport à la tige de support (4). Une carte de circuit de commande (5) est disposée à l'intérieur du boîtier (1) et est électriquement connectée au corps principal d'entraînement (201). Un premier commutateur (6) et un second commutateur (7) sont disposés sur la carte de circuit de commande (5). Le premier commutateur (6) commande le démarrage/l'arrêt de l'élément d'entraînement (2). Le second commutateur (7) est opposé à une extrémité du corps principal d'entraînement (201). Lorsque l'extrémité du corps principal d'entraînement (201) tourne pour entrer en contact avec le second commutateur (7), l'extrémité continue à tourner jusqu'à ce que l'état ouvert/fermé du second commutateur (7) ait changé et que la carte de circuit de commande (5) ait amené la sortie de l'élément d'entraînement (2) à ralentir ou à s'arrêter. La brosse à dents électrique est pourvue du corps principal d'entraînement (201) tournant par rapport à la tige de support (4), de telle sorte que, lorsque la tête (3) de brosse subit une pression dépassant un seuil prédéfini, l'extrémité du corps principal d'entraînement (201) puisse changer l'état ouvert/fermé du second commutateur (7) pour ralentir ou arrêter la sortie de l'élément d'entraînement (2), évitant qu'une force de brossage élevée endommage les dents ou les gencives pendant le brossage.
