POWERED TOOTHBRUSH HAVING THREE DIMENSIONAL ROTATIONAL HEAD MOTION

摘要

An electrically driven toothbrush having a rotatable drive shaft with an end , off-set from the central longitudinal axis of the drive shaft and lodged in a boring in a bristle carrier, which bristle carrier is orbitally secured with in a socket in the toothbrush head. When the drive shaft rotates, the end describes a circle and drivingly engages the bristle carrier to actuate the bristle carrier in a three dimensional reciprocating side-to-side and rockin g up-and-down motion.
