Abstract
An electric toothbrush with a replaceable brush head section is disclosed. The electric toothbrush includes a handle including a motor therein and a brush head section. The toothbrush has a longitudinal axis extending through the handle to the far end of the brush head. The brush head section includes a translation head and an oscillation head, each of which has a bristle support member, one of which will rotate and oscillate and the other of which will not rotate or oscillate, but will reciprocate along, or substantially parallel to, the longitudinal, axis. The translation head is adapted so that its motion will induce a different motion in the bristle head of the oscillation head. The invention results in reduced assembly costs.
