Abstract

The mechanical toothbrush head (20) carries tufts (42, 43), each consisting of separate bristles which are motor-driven and rotate on their centre axis. Each tuft first rotates in one direction, and then in the opposite direction, so that each tuft is simultaneously rotating in the contrary direction to the adjacent tuft. Each tuft as a slanting tip as determined by the free ends of the bristles which run to a point. The angle included by each sloping bristle tip is roughly 25 deg. The tufts are rotated by spur gears connected to each of them. A reciprocating bar drives the spur gears, mov%ed by an output shaft with a pinion (82) meshing with a crown wheel (84). To the crown wheel is pivot mounted, eccentrically, a crank arm (86) with a drive shaft (92) attached to the other end.
