ABSTRACT:
An electronic toothbrush including a head portion at one end which is studded with bristles, a grip portion in the middle which contains a battery, and a voltage tester at the other end which is separable from the grip portion and has a tester body with coupling means associated with the grip portion for separably coupling the tester body with the grip portion. The grip portion has a first electrically conductive member which is adapted to be touched by a user and is electrically connected to one pole of the battery, and a second electrically conductive member which is adapted to be electrically connected to the bristles and is electrically connected to the other pole. The tester has a light emitting member mounted inside the tester body and visible from outside the tester body, and a pair of electrical conductors extending from the light emitting member and being exposed at least partially from the tester body. When the pair of electrical conductors of the tester separated from the grip portion contact the first and second conductive members of the grip portion, the emission of light by the light emitting member is determined by the condition of the battery.
