  • Publication number: 20190125068
    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.

  • Publication number: 20180087631
    Abstract: An electrically driven device includes a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin eccentrically connected to the drive shaft, and a driven shaft having a second rotary axis and mounted in the housing for a pivoting movement. The driven shaft is coupled to the drive pin by a gear mechanism converting a rotary motion of the drive shaft into the reciprocating pivoting of the driven shaft. The gear mechanism has first and second transmission stages, the former including a cross slider, and the latter an elastically deformable transmission member. The cross slider has a sliding support extending perpendicular to the first rotary axis and receiving the drive pin. The cross slider is axially guided in the housing to move in an axial direction perpendicular to the first rotary axis and perpendicular to the extension of the sliding support. A link, offset relative to the second rotary axis, connects the cross slider to the elastically deformable transmission member.
