Abstract
A brush comprising a first motor to control a rotation of a brush head, a second motor to control a vibration of the brush head. In one embodiment, the brush further comprises a controller to control of a ratio between the rotation and the vibration.
Claims20
A cleansing brush including a brush head and a brush body, the cleansing brush comprising:
- a planetary gear system including a sun gear, a ring gear, and planetary gears;
- a first motor in the brush body coupled to the sun gear to drive movement of the sun gear in the planetary gear system to control a rotation of the brush head;
- a second motor in the brush body coupled to the ring gear to drive movement of the ring gear in the planetary gear system to control a vibration of the brush head;
- and
- wherein the sun gear and the ring gear drive the planetary gears, and the planetary gears combine the rotation from the first motor and the vibration from the second motor to create micro-rotations of the brush head;
- and
- a carrier coupled to the planetary gears and the brush head, the carrier to move the brush head.

A method of using a facial cleansing brush with a planetary gearing system comprising:
- setting a speed of rotation, using a first motor coupled to a sun gear to drive movement of the sun gear;
- setting a speed of vibration, using the second motor coupled to a ring gear to drive movement of the ring gear;
- and
- combining the rotation and the vibration, by planetary gears combining the rotation from the sun gear and the vibration movement from the ring gear, to create micro-rotations of a brush head, and moving the brush head by a carrier coupled to the planetary gears and the brush head.

A facial brush comprising:
- a vibration motor coupled to a ring gear to drive the ring gear to control a vibration motion of a brush head;
- a rotation motor coupled to a sun gear to drive the sun gear to control a rotation motion of the brush head;
- a planetary gearing including the sun gear and the ring gear, and planetary gears to combine the vibration motion and the rotation motion of the brush head to create micro-rotations;
- a carrier coupled to the planetary gears and to the brush head to move the brush head;
- and
- a user interface to enable a user to select a setting, the setting controlling a speed and ratio of the vibration and the rotation.
