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.

Claims

1. 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.

2. The brush of claim 1, further comprising:

a controller to adjust the first motor and the second motor to control a ratio between the rotation and the vibration.

3. The brush of claim 2, further comprising:

a user interface enabling a user to set the ratio.

4. The brush of claim 3, wherein the user interface comprises one of:

a preset adjustor enabling a user to select one of a set of preset rotation/vibration ratios, a ratio adjustor enabling the user to select a rotation/vibration ratio, and direct adjustor, enabling the user to select a rotation speed and a vibration level.

5. The brush of claim 1, wherein a speed of rotation of the first motor ranges from 0 RPM to 4000 RPM.

6. The brush of claim 1, further comprising:

a cap including a UV element to cover the brush head when the brush is not in use to sanitize the brush head.

7. The brush of claim 1 further comprising a cap to cover the brush head when the brush is not in use, the cap including a plurality of holes, and the cap allowing air to circulate around the brush head to enable it to dry, and allowing water to drain from the brush without making a mess.

8. The brush of claim 1, further comprising:

a brush head attachment to receive a removably attached brush head.

9. The brush of claim 8, further comprising:

a brush head identification mechanism, to identify a type of the removably attached brush head; and

a controller to adjust the ratio between the rotation and the vibration based on the type of the brush head.

10. The brush of claim 9, wherein the brush head identification mechanism comprises one of:

radio frequency identification tags (RFID), mechanical connection differentiation, weight, and user input.

11. The brush of claim 1, further comprising:

a sensor to detect a location and use of the brush with respect to a user'"'"'s face; and

a controller to adjust the first motor and the second motor, to control a movement of the brush head based on data from the sensor.

12. The brush of claim 11, wherein the controller turns off the rotation and the vibration when the brush is not touching the user'"'"'s face.

13. The brush of claim 2, further comprising:

a preparation identifier to identify a type of preparation being used with the brush; and

the controller to adjust the ratio between the rotation and the vibration based on the type of the preparation.

14. The brush of claim 2, further comprising:

a sensor to detect use data comprising or more of;

a body part, a direction of movement of the brush, a shape of the area being brushed, and a pressure; and

the controller to adjust a direction of the rotation of the brush head, based on the use data.

15. The brush of claim 1, further comprising:

a network connection to couple the brush to a mobile device, the mobile device to provide an improved user interface.

16. 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.

17. The method of claim 16, further comprising:

enabling a user to select a ratio between the rotation and the vibration.

18. The method of claim 16, further comprising:

detecting a passive ID indication in one of more of;

the brush head and a preparation used with the brush; and

adjusting the micro-rotations based on the passive ID.

19. The method of claim 16, further comprising:

detecting how the brush is being used, utilizing one or more sensors; and

adjusting one or more of;

a speed, a ratio, and a direction of the micro-rotations based on the detecting.

20. 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.
