The secondary tuft block may be oscillated in a rotational manner or may oscillate linearly back and forth in the same direction as the handle of the toothbrush. The secondary tuft block could be in the form of a pair of side by side plates mounted on the head adjacent to the round oscillating block. The invention could also be practice where the secondary tuft block is in the form of a plurality of sets of rows of bristles mounted for back and forth movement in a direction perpendicular to the handle. The secondary tuft block is connected to the primary tuft block by means of a drive transmitting connection.

L'invention concerne une brosse à dents électrique dont la tête de rechange combine un bloc de touffes principal ou oscillant rond typique qui oscille de façon rotative avec un bloc de touffes secondaire. Le bloc de touffes secondaire peut osciller en rotation ou linéairement vers l'arrière et l'avant dans le même sens que le manche de la brosse à dents. Ce bloc de touffes secondaire peut avoir la forme d'une paire de plaques juxtaposées montées sur la tête à côté du bloc oscillant rond. Selon un autre mode de réalisation de l'invention, le bloc de touffes secondaire prend la forme d'une pluralité de jeux de lignes de soies, montés pour un mouvement arrière et avant dans un sens perpendiculaire au manche. Le bloc de touffes secondaire est relié au bloc de touffes principal au moyen d'une liaison de transmission d'entraînement.
