Publication number: 20230363522Abstract: 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.Type: ApplicationFiled: July 25, 2023Publication date: November 16, 2023Inventors: Norbert SCHAEFER, Thomas FRITSCH, Andreas KRAMP, Andreas LARSCHEID, Marc KUNZ, Robert SCHÄFER

Patent number: 10881193Abstract: 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.Type: GrantFiled: October 12, 2018Date of Patent: January 5, 2021Assignee: Braun GmbHInventors: Norbert Schaefer, Martin Haas, Andreas Kramp, Robert Schäfer

Patent number: 10840767Abstract: An electrically driven device includes an electric motor with a drive shaft having a first rotary axis and a drive pin eccentrically thereto, and a driven shaft having a second rotary axis and mounted for pivoting motion. The driven shaft is coupled to the drive shaft by a scotch yoke mechanism, converting a rotary motion of the drive shaft into a reciprocating pivoting motion of the driven shaft. The scotch yoke mechanism includes a cross slider having a sliding support extending perpendicular to the first rotary axis and receiving the drive pin either directly or by a sliding block having a bearing receiving the pin. The cross slider is axially guided to move in an axial direction perpendicular to the first rotary axis and to the extension of the sliding support. The driven shaft is coupled to the cross slider by a pivotable crank arm, thereby converting a rotary motion of the drive shaft into a reciprocating motion of the driven shaft.Type: GrantFiled: September 25, 2017Date of Patent: November 17, 2020Assignee: Braun GmbHInventors: Thomas Fritsch, Andreas Kramp, Norbert Schaefer

Patent number: 10808810Abstract: 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.Type: GrantFiled: September 25, 2017Date of Patent: October 20, 2020Assignee: Braun GmbHInventors: Andreas Kramp, Thomas Fritsch, Norbert Schaefer
