Abstract

A skincare device having optimized dual energy modalities ace is presented. In an embodiment, a skincare device includes a body having protruding elements configured for contacting a skin of a user, where the protruding elements are configured to vibrate in operation. The skincare device also includes an end effector configured for contacting the skin of the user, where the end effector is configured to oscillate about a center axis in operation.

First claim

I claim:

1. A face massage skincare device, comprising:
a body having protruding elements configured for contacting a face of a user, wherein the body carries a resonant structure operably coupled to one or more of the protruding elements, the resonant structure being configured to generate vibrations of the one or more protruding elements during operation, wherein the protruding elements are fixedly connected with the body;
an end effector having a face brush configured for contacting the face of the user while the resonant structures vibrates, wherein the end effector is configured to oscillate about an axis during operation, and wherein the protruding elements are separate from the face brush;
a motor having a shaft configured to generate oscillations of the face brush;
the resonant structure comprising a source of vibration that is separate from the motor or the shaft; and
wherein the resonant structure further comprises: a first resonant structure extending peripherally along a first side of an outer edge of the body; a second resonant structure extending peripherally along a second side of the outer edge of the body, wherein the second side is opposite from the first side; and a third resonant structure extending between the first resonant structure and the second resonant structure.

2. The device of claim 1 , wherein:
the first resonant structure configured to resonate at a first resonant frequency; and
the second resonant structure configured to resonate at a second resonant frequency,
wherein the first resonant frequency is different from the second resonant frequency.

3. The device of claim 2 , wherein the protruding elements comprise a first plurality of protruding elements having a first size and a second plurality of protruding elements having a second size different from the first size, and wherein:
the first resonant structure is configured to impart the first resonant frequency onto the first plurality of protruding elements; and
the second resonant structure is configured to impart the second resonant frequency onto the second plurality of protruding elements.

4. The device of claim 3 , wherein the first plurality of protruding elements has a first shape and the second plurality of protruding elements has a second shape different from the first shape.

5. The device of claim 1 , wherein the first, second, and third resonant structures are metal wires or strips caused to vibrate at least in part by oscillations of the end effector.

6. The device of claim 1 , wherein the source of vibration comprises at least one piezoelectric element configured to constrict and expand based on a voltage supplied to the piezoelectric element.

7. The device of claim 1 , wherein the first and second resonant structures extend radially away from the face brush.

8. The device of claim 1 , wherein vibration of the protruding elements is at least in part caused by oscillations of the end effector.

9. The device of claim 8 , wherein the end effector carries at least one rotating first magnet and the body carries at least one stationary second magnet opposite from the rotating first magnet, and wherein the protruding elements vibrate at least in part based on magnetic interactions between the at least one rotating first magnet and the at least one stationary second magnet.

10. The device of claim 1 , wherein the body comprises an opening configured for placing a hand of the user into an interior of the device.

11. The device of claim 1 , wherein the body is made of silicon material.

12. The device of claim 1 , further comprising:
a first charging coil carried by a charging stand; and
a second charging coil carried by the body,
wherein the first charging coil is configured to receive electrical energy through electromagnetic interactions with the second charging coil.

13. The device of claim 1 , wherein the body comprises a printed circuit board (PCB) with a controller configured to control operation of the end effector.

14. A face massage skincare device, comprising:
an oscillating brush head configured to contact a face of a user, wherein the brush head is configured to oscillate about an axis during operation; and
a body having protruding elements configured to contact the face of the user, wherein the body carries a resonant structure operably coupled to one or more of the protruding elements that are configured to vibrate in response to a source of vibrations while the brush head oscillates, and wherein the protruding elements are separate from the brush head, wherein the protruding elements are fixedly connected with the body;
a motor having a shaft configured to generate oscillations of the brush head;
the resonant structure comprising a source of vibration that is separate from the motor or the shaft; and
wherein the resonant structure further comprises: a first resonant structure extending peripherally along a first side of an outer edge of the body; a second resonant structure extending peripherally along a second side of the outer edge of the body, wherein the second side is opposite from the first side; and a third resonant structure extending between the first resonant structure and the second resonant structure.

15. The device of claim 14 , wherein the source of vibration is a piezoelectric element configured to constrict and expand based on a voltage supplied to the piezoelectric element.

16. The device of claim 14 , wherein the first and second resonant structures extend radially away from the brush head.

17. The device of claim 14 , wherein:
the first resonant structure configured to resonate at a first resonant frequency; and
the second resonant structure configured to resonate at a second resonant frequency,
wherein the first resonant frequency is different from the second resonant frequency.

18. The device of claim 17 , wherein the protruding elements comprise a first plurality of protruding elements having a first size and a second plurality of protruding elements having a second size different from the first size, and wherein:
