Patent ID: 7082638

Claim:
An electro-motion toothbrush comprising: an upper tooth cover surrounding and covering the upper teeth having a first inner and a first outer surface, the first inner surface has bristles formed at a surface contacting the teeth; a lower tooth cover surrounding and covering the lower teeth having a second inner and a second outer surface, the second inner surface has bristles formed at a surface contacting the teeth; a first driving rod combined with the first and second outer surfaces of the upper and lower tooth covers; a second driving rod combined with a left side of the first and second outer surfaces of the upper and lower tooth covers; a third driving rod combined with a right side of the first and second outer surfaces of the upper and lower tooth covers; a plurality of sensors, independently sensing positions of the first, second, and third driving rods; reciprocating means driving the first driving rod and the second and third driving rods in opposite directions to move the upper and lower tooth covers in opposite directions and thereby clean the teeth, the reciprocating means driven by power supplied from a motor, in response to position information sensed by the plurality of sensors.
