Tooth cleaning mechanism

摘要

A tooth cleaning device for the disabled eliminates the need for the user to rotate her/his wrist while brushing teeth, and provides approximately the same profile as a standard manual toothbrush. The device is capable of effectively brushing all three sides of all upper or lower teeth simultaneously, and utilizes a commercially available battery powered toothbrush power source to provide the power necessary for effective teeth cleaning action. An open top U-shaped track has a number of distinct operatively connected brush bristle mounting heads reciprocal and retained within the track, with a number of bristles extending up from each of the heads. A device, such as an opening in a central head, a linkage, and a battery powered oscillating shaft, provide back and forth arcuate reciprocal movement of the heads within the track to provide tooth cleaning by the bristles.
