ABSTRACT:
The invention is directed to an electric toothbrush provided with a protective cover which is adapted to be pushed onto the handle section of the toothbrush. The protective cover protects in particular the drive shaft of the toothbrush extending from the handle section from contaminants, liquids as well as the impact of forces. The protective cover is further provided with a safety interlock preventing an accidental operation of the electric toothbrush when the protective cover is seated in place. A notch already provided is used for accomplishing a firm locking engagement of the protective cover with the handle section. The embodiments described cover both an integral and a two-part structure of the protective cover.
