Abstract

L'invention concerne une brosse à dents électrique dont la partie de corps est de conception légère et compacte et capable de renforcer un effet de brossage des dents et un effet de massage sans causer de désagrément et d'empêcher le recourbement permanent de la partie d'extrémité formée d'une touffe de poils. Une membrane souple (13) se déplaçant conjointement avec un corps de base (10) d'une brosse (9) effectuant un mouvement de va-et-vient est installée entre un espace (2) pour partie de corps et un passage (6) de guidage de brosse, et un trou d'admission d'air (15) comportant une valve d'ouverture/de fermeture (14) s'ouvrant uniquement vers l'intérieur est ménagé dans la partie de corps au milieu du passage (6) de guidage de brosse. Lorsque la membrane (13) est déplacée du côté de l'espace (2) pour partie de corps en fonction du mouvement de va-et-vient du corps de base (10), de l'air est entraîné du trou d'admission d'air (15) au passage (6) de guidage de brosse pour y créer une pression négative, et lorsque la membrane (13) est déplacée du côté du passage (6) de guidage de brosse, l'air entraîné dans celui-ci est comprimé et expulsé par une ouverture (6a) à l'extrémité du passage de guidage de brosse. La partie de corps peut donc être dotée d'une conception légère et compacte et l'effet de brossage des dents et l'effet de massage peuvent être renforcés sans causer de désagrément.
