Abstract
An electric toothbrush comprising an elongated body portion and a head including a static portion and a moving portion, a handle, and an angled shaft between the head and the handle. The moving portion rotates or reciprocates about an axis normal to a longitudinal axis of the head. The moving portion can include stiff bristles and massaging tips and the static portion can include soft bristles and massaging tips. The elongated body portion is hollow and further includes a motor in the hollow portion, which is operatively connected to the moving portion for rotating or oscillating or reciprocating the moving portion. A battery is located within the hollow section for powering the motor. A switch is operatively connected to the motor to provide momentary and continuous operation of the toothbrush. A worm gear and a pair of step gears are located in the hollow portion. The motor is operatively connected to the worm gear and the step gears are operatively connected to the worm gear and to each other. One of the step gears is offset with respect to a longitudinal axis of the elongated body portion. A shaft which is operatively connected to the offset step gear and to a second end to the moving portion. Alternately, the toothbrush comprises a plurality of gears and swivel arms which move the brush head moving portion in a rotating, oscillating or reciprocating manner.
