The utility model provides a skin treatment device.

Referring to fig. 1, a skin treatment device 10 according to a first preferred embodiment of the present invention includes a control unit 11, an energy source 12, an operation interface 13, a radio frequency energy generating unit 14, a switching unit 15, at least two electrode pairs 16, and a sensor 17. The control unit 11 is in signal connection with the operation interface 13, the radio frequency energy generating unit 14, the switching unit 15 and the sensor 17. The energy source 12 provides energy. The at least two electrode pairs 16 are electrically connected to the rf energy generating unit 14 through the switching unit 15.

The number of the control units 11 may be one or more. A plurality of different controls 11 may be linked by suitable connections for synchronous operation. For example, if two controls 11 are used, one of the controls 11 is used to control one of the sets of electrode pairs 16 to independently control the application of radio frequency energy to the skin, and the other control 11 is used to control the other set of electrode pairs 16 to independently control the application of radio frequency energy to the skin.

The energy source 12 is used for providing energy for the control part 11, the operation interface 13, the radio frequency energy generation unit 14, the switching unit 15 and the sensor 17. It is to be noted that the energy source 12 may be inside the skin treatment appliance 10, or may be arranged outside the skin treatment appliance 10 and supply energy to elements within the skin treatment appliance 10 via leads. For clarity of presentation, the electrical connections of the energy source 12 and the various components of the skin treatment appliance 10 that require electrical energy are not shown in fig. 1. Additionally, the energy source 12 may be any suitable type of DC or AC power source known in the art, such as a rechargeable battery, a photovoltaic cell, or an AC power outlet, among others.

The operation interface 13 is adapted to be connected to the control section 11 for receiving an output signal and data of the control section 11 and for inputting a command or a control signal of a user to the control section 11. For example, the operation interface 13 may be a combination of any displays for presenting virtual output to a user.

The construction and implementation of the radiofrequency energy generation unit 14 is well known in the art and is not the subject of the present invention and will therefore not be described in detail below. In general, any suitable type of radio frequency energy generating unit known or commercially available in the art may be used to implement the various embodiments disclosed in this application. In the present embodiment, the rf energy generating unit is constructed to operate at an rf frequency of 0.1 to 10.0 MHz.

The switching unit 15 comprises a plurality of controllable switches (not shown). The control section 11 can independently control each switch included in the switching unit 15. Through the switching unit 15, the control portion 11 can controllably change the connection between the rf energy generating unit 14 and any one set of the electrode pairs 16. That is, the rf energy generated by the rf energy generating unit 14 can be repeatedly applied by switching between the two electrode pairs 16. For example, the control unit 11 may stop the operation of one of the electrode pairs 16 and start the operation of the other electrode pair 16.

Referring to fig. 2, each of the electrode pairs 16 includes a positive electrode 161 and a negative electrode 162, and radio frequency current flows between the positive electrode 161 and the negative electrode 162 of the electrode pair 16. The positive electrode 161 and the negative electrode 162 are required to be in good contact with the skin 20 during treatment. It is noted that the two sets of electrode pairs 16 may share one of the electrodes.

The sensor 17 is used to sense a skin parameter, and/or the temperature of the two sets of electrode pairs 16. In the present embodiment, the sensor 17 induces the temperature of the electrode pair 16 that is operating, thereby causing the control unit 11 to switch between the electrode pair 16. That is, if the temperature of one electrode pair 16 exceeds a predetermined threshold, the control unit 11 is configured to switch to another electrode pair 16 that is relatively cool to continue operating. It is understood that the sensor 17 may be selected from a body surface temperature sensor, an electrode temperature sensor, and combinations thereof.

Referring to fig. 1 and 2, when the skin treatment device 10 is applied to the skin 20, the two sets of electrode pairs 16 have different spatial positions on the skin 20, and when the skin area corresponding to one set of electrode pairs 16 is overheated, the control portion 11 stops the operation of the set of electrode pairs 16 and seamlessly switches to the other set of electrode pairs 16 to continue the operation, so that the skin can be prevented from being scalded without stopping the operation, thereby not causing more treatment courses and longer treatment time, and not increasing the cost.

The second embodiment:

referring to fig. 3, a second preferred embodiment of the skin treatment device of the present invention is different from the first preferred embodiment in that: the number of the rf energy generating units 14 is plural, and each rf energy generating unit 14 can operate in a specific and different rf frequency band, that is, the rf frequency bands of different rf energy generating units 14 can partially overlap or completely differ.

For example, according to one possible non-limiting example of the radiofrequency energy generation units 14, the number of radiofrequency energy generation units 14 is 2, namely a first radiofrequency energy generation unit 14A and a second radiofrequency energy generation unit 14B. The first rf energy generating unit 14A is configured to operate at an rf frequency of 0.5 MHz. The second radiofrequency energy generation unit 14B is configured to operate at a radiofrequency frequency of 10.0MHz, it being possible to deliver to the skin a radiofrequency frequency combination of:

1) each set of

electrode pairs

16A and 16B provides a combination of radio frequency frequencies (0.5MHz +10.0MHz) to the skin.

2) A radio frequency of 0.5MHz is applied to the skin through electrode pair 16A and a radio frequency of 10.0MHz is applied to the skin through electrode pair 16B.

3) A radio frequency of 0.5MHz is applied to the skin via electrode pair 16B and a radio frequency of 10.0MHz is applied to the skin via electrode pair 16A.

4) The radio frequency of 0.5MHz is applied to the skin through electrode pair 16A and the radio frequency (0.5MHz +10.0MHz) is applied to the skin through electrode pair 16B.

5) The radio frequency of 0.5MHz is applied to the skin through electrode pair 16B and the radio frequency (0.5MHz +10.0MHz) is applied to the skin through electrode pair 16A.

Since the RF electrode pairs 16A and 16B have different spatial locations on the skin, each of the above five possible electrode pair and frequency combinations indicate a different and unique pattern of applied RF energy to the skin. In this way, when the skin in a certain area is overheated, the skin can be prevented from being scalded by changing the radio frequency energy of the radio frequency energy generating unit and/or the working electrode pair.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
