<p>An electric toothbrush having a particular assembly, bristle configuration, and drive mechanism is disclosed. The assembly, bristle configuration, and drive mechanism are such that operation of the brush is highly efficient and more economical than currently known toothbrushes. Specifically, an electric toothbrush is disclosed comprising a body, a head, and a neck extending therebetween. The head utilizes one of several unique and preferred arrangements of static and movable bristles. The static bristles at least partially surround the collection of movable bristles which are provided on a movable bristle carrier. A motor and drive train impart motion to the collection of movable bristles. Also disclosed is a toothbrush having a simplified and improved assembly. The toothbrush includes a unique assembly utilizing a one-piece housing in combination with a movable bristle carrier that is engaged on a brush head of the toothbrush, and a stationary brush head tip which is secured thereto. The unitary housing reduces the number of components of the toothbrush and decreases manufacturing costs. The brush head tip may be replaced with other tips and allows a consumer to individually tailor the brush to provide a particular brushing configuration as desired.</p> |
