ABSTRACT:
An improved electric toothbrush assembly including a handle and a brush portion. The handle has an output shaft which is provided with a vertical positioning rod. The brush portion includes a brushing housing, a brush cover, a brush rod received between the brush housing and brush cover, and two brush heads. The brush housing is coupled to the handle as well as the brush cover. The housing is provided with a brush face formed with two parallel elongated face slots. The brush cover is provided with a cover pin projecting from a middle section thereof. The brush rod has hooks at a bottom side thereof, a vertical elongated slot near a middle section thereof and two grooves at an upper side thereof corresponding to the brush face of the brush housing. The brush heads are each provided with brush axles received therein which pass through the grooves of the brush rod and the face slots of the brush housing. The hooks of the brush rod engage the positioning rod of the handle. The cover pin passes through the slot of the brush rod. When the output shaft of the handle performs linear movement, it will bring the brush rod to reciprocate in a linear direction while the brush heads displace inwardly and outwardly respectively in relation to the brush face when the brush axles move along the grooves of the brush rod.
