Abstract:
A ion toothbrush comprising:a head with brush bristles implanted therein; a handle for a user to hold; and a battery received in the handle, wherein one electrode of the battery is conductively connected with the external surface of the handle and the other electrode of the battery is conductively connected with the vicinity of the implanted area of the brush bristles at the head, and the ion toothbrush further comprising: an illuminate with its one terminal connected to one electrode of the battery and with its other terminal connected to the other electrode of the battery; a conductive spindle capable of conductively connecting the other electrode of the battery with the vicinity of the implanted area of the brush bristles and also capable of conductively connecting with the other terminal of the illuminant; a switch for opening and closing an electric circuit including the illuminant, the conductive spindle, and the battery; a first connector for electrically connecting one electrode of the battery with one terminal of the illuminant; and a second connector for electrically connecting the other electrode of the battery with the other terminal of the illuminant, wherein at least one of the first and second connectors electrically connects, because of its elasticity, with the battery, wherein one end of the first connector is secured to the handle and the other end of the first connector is urged by its elasticity toward one electrode of the battery.
