Abstract

L'invention concerne une brosse à dents électrique comportant une brosse rotative entraînée mécaniquement. Le sens de rotation de la brosse est commandé automatiquement en fonction des dents à brosser, selon qu'il s'agit des dents du haut ou des dents du bas, afin d'enlever tous les débris alimentaires sur les dents et les gencives, dans une direction s'éloignant des gencives. La brosse à dents, selon l'invention, utilise un élément de commande de direction qui est placé à l'intérieur de la bouche entre les dents du haut et les dents du bas. L'élément de commande de direction commande le sens de rotation de la brosse et permet de stabiliser cette dernière par rapport aux dents au cours de l'opération de brossage. Le mouvement de l'élément de commande de direction actionne un inverseur de marche pour changer le sens de rotation de la brosse et assurer un brossage dans un sens s'éloignant des gencives et en direction des dents sans devoir pour autant retirer la brosse à dents de la bouche.
