Abstract
An electric toothbrush comprising a head (16) including a static portion (22) and a moving portion (20). The moving portion (20) rotates or reciprocates about an axis normal to a longitudinal axis (19) of the head (16). The moving portion (20) can include stiff bristles (24) and massaging tips (325) and the static portion (22) can include soft bristles (26) and massaging tips (327). A
switch (50) is operatively connected to a motor (32) to provide momentary and continuous operation of the toothbrush. The motor (32) is operatively connected to a worm gear (40) and step gears (42, 43). One of the step gears (43) is offset with respect to a longitudinal axis (36) of the elongated body portion (10). A shaft (44) is connected to the offset step gear (43) and to a second end to the moving portion (20). Alternately, the toothbrush comprises a plurality of gears (202, 206) and swivel arms (220, 224, 240) which move the brush head (160) moving portion (164) in a rotating, oscillating or reciprocating manner.
