摘要：
The present disclosure is concerned with a personal hygiene device having a handle, a treatment head, a motor carrier disposed in the handle and that is pivot mounted against at least one spring element arranged between the handle and the motor carrier, a motor having a stator portion that is fixedly mounted at the motor carrier and an armature portion that is spring mounted at the motor carrier to allow a motion relative to the motor carrier, the armature portion being coupled with a drive shaft connected with the treatment head for transferring motion to the treatment head, wherein an external treatment force acting on the brush head in a treatment direction leads to pivoting of the motor carrier around a pivot axis relative to the handle, the motor comprising a motor permanent magnet and a coil element for providing an alternating electromagnetic field interacting with the motor permanent magnet so that an oscillating motion of the drive shaft is excited in operation, a Hall sensor mounted in fixed relationship to the handle or to the motor carrier, and a sensor permanent magnet, in particular of cylindrical shape, mounted in fixed relationship to the other one of the handle or motor carrier so that a pivoting motion of the motor carrier leads to a relative movement between the sensor permanent magnet and the Hall sensor.
