Abstract

La présente invention se rapporte à une brosse à dents électrique dotée d'une brosse rotative à laquelle est appliquée une brosse double, pour éviter d'endommager la gencive des utilisateurs pour qui il est compliqué de se brosser les dents ou qui ont des difficultés à bouger, comme les enfants ou les patients, et pour permettre un brossage de dents très propre, y compris une élimination efficace des agents de contamination. Grâce à la brosse à dents électrique ayant une nouvelle forme par l'application de la brosse double afin de permettre un déplacement idéal entre les dents et les poils, on peut éviter l'endommagement de la gencive et les agents de contamination restant sur les dents peuvent être efficacement éliminés. L'invention se rapporte également à une brosse à dents électrique dotée de la brosse rotative qui peut particulièrement améliorer la fonction de mise en marche d'une sous-brosse grâce à une nouvelle forme de support de sous-brosse pour un déplacement avec une tête et un manche, en fonction de l'accouplement de la tête, lorsque la tête est accouplée au manche et simultanément pour l'assurance d'un support stable.
