Abstract
An electrically powered toothbrush comprises a body having a first end, a head opposite from the first end, and a neck extending between the first end and the head. The body defines a hollow region therewithin. An electrical motor and a power source are disposed in the hollow region within the body. A drive shaft having a longitudinal axis of rotation and a distal end offset from the axis of rotation is operatively connected to the motor for rotational movement. A base pivotally secured to the head by a laterally extending pivot member has a receiving channel for receiving the distal end of the drive shaft. A first bristle carrier is secured to the base, and a second bristle carrier is disposed on the head between the first bristle carrier and the first end. Rotation of the drive shaft causes its distal end to move within the receiving channel thereby causing the base with the first bristle carrier to pivot about the laterally extending pivot member.
