Abstract

In a mouth- and tooth-spray apparatus, the energy supply to an electric motor in the apparatus base is supplies by means of a rechargeable battery of an electric toothbrush. For this purpose, the electric toothbrush is to be inserted into a toothbrush receiver of the apparatus base, exactly as into a conventional charging device.

By means of this design, the mouth- and toothspray apparatus requires no high voltage power supply connections. Instead, it is exclusively operated with low voltage.

Claims

1. Mouth- and tooth-spary apparatus comprising an apparatus base, a water container mounted on said base, a handpiece containing a spray nozzle removably mounted on said base, said base containing an electric motor and a water pump driven thereby, said electric motor being a low-voltage motor, the terminals of which are detachably connected to a rechargeable battery disposed in an electric toothbrush, said pump being operatively connected between said container and said handpiece to pump water from said container to said nozzle.

2. Mouth- and tooth-spray apparatus according to claim 1, wherein the apparatus base further contains receiver means for the electric toothbrush and contact means disposed in the receiver means and connected to the electric motor to take electrical energy out of the battery of the toothbrush.

3. Mouth- and toothspray apparatus according to 1, wherein the apparatus base is connected via a low-voltage cable to an electric charging device for an electric toothbrush, and this low-voltage cable is connected in the charging device, with the toothbrush inserted, to the battery of the toothbrush.

4. Mouth- and tooth-spray appartus according to claim 1, further comprising an electrical charging device for an electric tootbrush arranged in the apparatus base.
