  • Electric drive unit for generating an oscillating displacement
    Patent number: 7675203
    Abstract: 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.
    Type: Grant

  • Electric toothbrush
    Patent number: 7469440
    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.
