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/We claim:

1 . A skincare device, comprising:
a body having protruding elements configured for contacting a skin of a user, wherein the protruding elements are configured to vibrate during operation; and an end effector configured for contacting the skin of the user, wherein the end effector is configured to oscillate about an axis during operation.

2 . The device of claim 1 , wherein the body carries a resonant structure operably coupled to one or more of the protruding elements, the resonant structure configured to generate vibrations of the one or more protruding elements.

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

4 . The device of claim 3 , 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.

5 . The device of claim 4 , 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.

6 . The device of claim 2 , wherein the resonant structure is a metal wire or strip caused to vibrate at least in part by oscillations of the end effector.

7 . The device of claim 2 , wherein the resonant structure comprises at least one piezoelectric element configured to constrict and expand based on a voltage supplied to the piezoelectric element.

8 . The device of claim 2 , wherein the resonant structure extends radially away from the end effector.

9 . The device of claim 1 , wherein the end effector is a face brush.

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

11 . The device of claim 10 , 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.

12 . The device of claim 1 , wherein the body comprises an opening for a hand of the user.

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

14 . 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.

15 . 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.

16 . A skincare device, comprising:
an oscillating brush head configured to contact a skin of a user; and a body having protruding elements configured to contact the skin of the user, wherein the protruding elements are configured to vibrate in response to a source of vibrations.

17 . The device of claim 16 , wherein the source of vibrations is a resonant structure carried by the body.

18 . The device of claim 17 , wherein the resonant structure is a piezoelectric element configured to constrict and expand based on a voltage supplied to the piezoelectric element.

19 . The device of claim 17 , wherein the resonant structure extends radially away from the end effector.

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

21 . The device of claim 20 , 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.

22 . The device of claim 16 , further comprising:
a motor; a shaft mechanically connecting the motor with the oscillating brush head; a first plurality of magnets carried by the oscillating brush head; and a second plurality magnets carried by the body, where the second plurality of magnets faces the first plurality of magnets at least at some angular positions of the oscillating brush head, wherein the resonant structure is a plurality of metal wires or strips configured to vibrate at least in part based on interactions between the first plurality of magnets and the second plurality of magnets.
