Abstract

L'invention concerne une partie (20) de brosse à dent électrique présentant une structure simple. Dans cette brosse à dent électrique, la plaque (11) du porte-poils décrit un mouvement oscillant autour d'un axe longitudinal, et les poils (15) décrivent également un mouvement rotatif oscillant autour de leur axe vertical. Les ensembles entraînement ménagés à cet effet dans la partie de brosse (20) comprennent essentiellement une tige transversale (8) qui est guidée dans une coulisse oblique (10) et qui est reliée à une barre de poussée (7). Cette barre de poussée (7) est dentée au niveau de son extrémité antérieure et s'engrène avec des roues dentées (16) du porte-poils (14).
