Abstract

An electric toothbrush with rolling motion. Three portions thereof, a movable toothbrush head support (1), a toothbrush head roller (2), and a gear motor (5), are detachably connected, and therefore, a long service life can be achieved simply by replacing the toothbrush head roller (2), thus reducing costs in use. Bristles on the toothbrush head roller (2) are arranged perpendicularly to a direction of an axis of the gear motor, and have a perpendicular contact with a tooth surface when the gear motor (5) is in motion, thus facilitating the contact with various surfaces of a tooth, and accordingly cleaning of the tooth. A middle portion of the bristles is embedded to protrude from another portion of the bristles on the two sides, enabling better cleaning of hard-to-reach areas. An advanced control circuit is employed to enable wireless inductive charging of the electric toothbrush, and the electric toothbrush enables the toothbrush head roller (2) to roll in both directions, thus being applicable to daily teeth cleaning.
