ABSTRACT:
The power toothbrush, which has a rotating brushhead movement, includes a housing with a motor mounted therein having an armature which in operation rotates through an arc of predetermined magnitude. The toothbrush also includes a brushhead mounted on a shaft which is connected to an output mass. A spring assembly couples the armature to the output mass, the spring assembly including two spring portions with a node point therebetween, wherein when the armature rotates, the brushhead moves in an opposite direction. The frequency of the movement of the armature is set equal to the resonant frequency of the spring coupling system and the output assembly.
