  • Patent number: 11964375
    Abstract: A multi-speed, power-driven tool may include a transmission mechanism that transmits power from a motor to an output device. A speed selection mechanism may be coupled to the transmission mechanism, to control a speed reduction through the transmission mechanism, and an output speed of the tool. The transmission mechanism may employ a compound, stepped, planetary gear assembly, to provide for an axially compact arrangement of transmission mechanism components, to reduce an axial length of the tool. The speed selection mechanism may employ a multi-staged grounding device, corresponding to the reduced axial length of the transmission mechanism.

  • Publication number: 20230363522
    Abstract: A personal hygiene device has a handle and a treatment head pivotably connected with the handle. Applying a treatment force against the treatment head causes a pivoting of the treatment head relative to the handle. A sensor, such as, e.g., a Hall sensor, fixedly secured with respect to one of the handle and the treatment head, measures a measurement variable. A sensor cooperation unit defines or influences the measurement variable in dependence on the relative position of the sensor and the sensor cooperation unit, such e.g., as a sensor permanent magnet, fixedly secured relative to one of the handle and the treatment head. A spring unit defines a rest position of the treatment head when no treatment force is applied. The spring unit has a first spring constant in the treatment direction and a second spring constant in a lateral direction, the second spring constant being at least about two times higher than the first spring constant.

  • Patent number: 10881193
    Abstract: A personal hygiene device has a handle, a treatment head, and a motor carrier disposed in the handle. The motor is pivot-mounted against at least one spring element arranged between the handle and the motor carrier. The motor has a stator portion fixedly mounted at the motor carrier and an armature portion spring mounted at the motor carrier to allow a motion relative to the motor carrier. The armature portion is coupled with a drive shaft connected with the treatment head for transferring motion thereto, wherein an external treatment force acting on the brush head leads to pivoting of the motor carrier relative to the handle. The motor has a motor permanent magnet and a coil for providing an alternating electromagnetic field interacting therewith to excite an oscillating motion of the drive shaft.
