Dual motor apparatus
An apparatus comprising a first motor to control a rotation and a second motor to control a vibration of a moving portion of the apparatus. In one embodiment, the apparatus further comprises a controller to control of a ratio between the rotation and the vibration.
1. An apparatus comprising:
a first motor and a second motor in a body of the apparatus;
a planetary gear system in the body of the apparatus, the planetary gear system including a sun gear, a ring gear, and planetary gears, wherein the first motor is coupled to the sun gear to drive movement of the sun gear in the planetary gear system to control rotation, and the second motor is coupled to the ring gear to drive movement of the ring gear in the planetary gear system to control vibration, 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; and
a carrier coupled to the planetary gear system to move a moving portion of the apparatus, the moving portion coupled to a head, the head designed to be in contact with a user when the apparatus is in use.
2. The apparatus of claim 1 , wherein the head comprises a brush head, and the apparatus is a skin brush.
3. The apparatus of claim 2 , wherein the brush head of the skin brush comprises one of bristles, massagers, a rough surface, nubs, silicone, fibers, a disk, and a pad.
4. The apparatus of claim 2 , wherein the brush head of the skin brush is adapted for one or more of applying a preparation, exfoliation, microdermabrasion, massaging, and acne management.
5. The apparatus of claim 1 , wherein the apparatus comprises a hairbrush, wherein the body of the apparatus comprises a handle of the hairbrush and the head comprises bristles of the hairbrush.
6. The apparatus of claim 5 , wherein the bristles of the hairbrush rotate and vibrate.
7. The apparatus of claim 1 , wherein the head comprises a toothbrush head, and the apparatus is an electric toothbrush.
8. The apparatus of claim 7 , wherein the head includes a plurality of bristles, and the bristles of the toothbrush rotate and vibrate.
9. The apparatus of claim 1 , wherein the head comprises a massager head, and the apparatus is a massager.
10. The apparatus of claim 9 , wherein the head is a massager head that rotates and vibrates.
11. The apparatus of claim 9 , wherein a combination of the rotation and the vibration produces microrotations.
12. A skin brush comprising:
a body designed to be held by a user, and a head coupled to the body designed to be applied to skin;
a first motor and a second motor in the body of the skin brush;
a planetary gear system in the body of the skin brush, the planetary gear system including a sun gear, a ring gear, and planetary gears, wherein the first motor is coupled to the sun gear to drive movement of the sun gear in the planetary gear system to control rotation, and the second motor is coupled to the ring gear to drive movement of the ring gear in the planetary gear system to control vibration, 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; and
a carrier coupled to the planetary gear system to move a moving portion of the skin brush, the moving portion coupled to the head, the head designed to be in contact with the skin when the apparatus is in use.
13. The skin brush of claim 12 , wherein the head of the skin brush comprises one of bristles, massagers, a rough surface, nubs, silicone, fibers, a disk, and a pad.
14. The skin brush of claim 12 , wherein the head of the skin brush is adapted for one or more of applying a preparation, exfoliation, microdermabrasion, massaging, and acne management.
15. The skin brush of claim 12 , wherein the head of the skin brush is adapted to be a massager.
16. A hairbrush comprising:
a brush handle and a brush head, the brush head including a plurality of spokes;
a first motor and a second motor in the hairbrush;
a planetary gear system, the planetary gear system including a sun gear, a ring gear, and planetary gears, wherein the first motor is coupled to the sun gear to drive movement of the sun gear in the planetary gear system to control rotation, and the second motor is coupled to the ring gear to drive movement of the ring gear in the planetary gear system to control vibration, 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; and
a carrier coupled to the planetary gear system to move a moving portion of the hairbrush, the moving portion coupled to the brush head, the brush head including the plurality of spokes designed to be in contact with a user when the apparatus is in use.
17. The hairbrush of claim 16 , wherein the spokes of the hairbrush comprise one of bristles, silicone, and fibers.
18. The hairbrush of claim 17 , wherein the bristles in the head of the hairbrush are designed to move in micro-rotations combining the rotation and the vibration.
