ABSTRACT:
An electric toothbrush including a pressure fluid device for applying fluid under pressure to teeth to be cleaned or to a bristle set. The pressure fluid device includes a pressure fluid supply in the interior of a movable drive translator. A brush part with a carrier tube is movably mounted with a drive translator therein adapted to be coupled to a drive element in a handle part. A movably mounted bristle carrier mounts a set of bristles and is adapted to be driven in an oscillatory manner by the drive translator. A motor in the handle part drives a drive element adapted to be coupled to a drive element in the brush part and with a pressure fluid conveying device driven by the motor. A pressure fluid channel, which directs the pressure fluid to the toothbrush head, is integrated into the drive translator.
