Abstract
The power toothbrush includes a driving assembly which in turn includes a DC motor () and a battery. The DC motor has a rotating drive shaft (), supported at its free end. The drive shaft has an eccentric portion (). Mounted on the eccentric portion is a plastic sleeve () having an extending portion which engages one end of a spring member (). The other end of the spring member is secured to a yoke () which is secured to a brushhead shaft (). Rotation of the drive shaft results in the extending portion of the plastic sleeve, moving the spring between a compressed state and an extended state. The action of the DC motor excites the spring to produce an oscillating action of the brushhead shaft and a brushhead assembly () mounted thereon.
