An electric drive unit for generating an oscillating movement, having a stator, a rotor, a torsion element and a tuning element. The tuning element acts upon the torsion element and serves to mechanically tune the resonant frequency of the drive unit.

Electric drive unit for generating an oscillating displacement

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.
