[0037] refer to Figures 2 to 7 As shown, the RF electrode assembly according to the first embodiment of the utility model is applied to a RF handle 10. The RF handle 10 is provided with a shell 100. The shell 100 is used to accommodate the RF electrode assembly. The RF electrode assembly includes a RF electrode 200, a temperature sensor 300 and a heat dissipation module 400.

[0038] Among them, a accommodating cavity is formed in the shell 100, and the RF electrode 200 and the heat dissipation module 400 of the RF electrode assembly can be arranged in the accommodating cavity. A clearance hole 101 can be provided at the end of the shell 100, and the end of the shell 100 away from the clearance hole 101 can be connected to the pipeline 30, and the other end of the pipeline 30 can be connected to the beauty instrument body 20.

The cooling medium delivery pipe is used to connect to the heat dissipation module 400. The desktop RF skin therapy instrument controls the operation of the RF handle 10 through a plurality of wires.

[0039] The radio frequency electrode 200 includes a connecting portion 201 and a probe 202. The outer peripheral wall of the probe 202 at one end close to the connecting portion 201 is formed with an extension portion 203 protruding outward, and the extension portion 203 is connected to the connecting portion 201. For example, the extension portion 203 and the connecting portion 201 can be connected by fasteners, bonding, clamping or other suitable methods. In the utility model, the extension portion 203 is provided to make it more convenient to connect the probe 202 and the connecting portion 201. A first mounting surface 204 may be formed on one side of the extension 203 close to the connection part 201, and a second mounting surface matching the first mounting surface 204 may be formed on one side of the connection part 201 close to the extension 203. The first mounting surface 204 and the second mounting surface may fit together, and at least one of the first mounting surface 204 and the second mounting surface may be provided with a wiring groove 205. For example, the first mounting surface 204 may be provided with a wiring groove 205, or the second mounting surface may be provided with a wiring groove 205, or both the first mounting surface 204 and the second mounting surface may be provided with a wiring groove 205. The probe 202 is inserted through the clearance hole 101 and extends outside the housing 100 to facilitate cosmetic treatment, and the probe 202 is provided with a mounting hole 206.

[0040] The temperature sensor 300 is arranged in the mounting hole 206. The temperature sensor 300 can be a contact temperature sensor, for example, it can be a thermistor temperature sensor or a thermocouple temperature sensor. The temperature sensor 300 is connected to a first wire 301, and the first wire 301 is passed through the wiring groove 205. The first wire 301 is used to connect the beauty instrument body 20 to realize signal transmission between the temperature sensor 300 and the beauty instrument body 20.

[0041] The heat dissipation module 400 is connected to the connection portion 201 . The heat dissipation module 400 may be air-cooled or liquid-cooled to cool the radio frequency electrode 200 .

[0042] According to the radio frequency electrode assembly of the present utility model, during use, the heat dissipation module 400 can absorb the heat of the contact area between the radio frequency electrode 200 and the human skin, thereby being able to reduce the temperature of the contact area between the radio frequency electrode 200 and the human skin and avoiding skin burns caused by excessive temperature. At the same time, the temperature sensor 300 can monitor the temperature of the contact area between the radio frequency electrode 200 and the human skin. Moreover, since the temperature sensor 300 is directly installed inside the probe 202, when the probe 202 contacts the human skin, the temperature of the contact area between the radio frequency electrode 200 and the human skin can be directly detected through heat conduction, and the temperature monitoring is more accurate. In addition, the radio frequency electrode 200 is of a split structure, including a connecting portion 201 and a probe 202 connected to each other. At least one of the first mounting surface 204 of the outer extension portion 203 of the probe 202 and the second mounting surface of the connecting portion 201 is provided with a wire groove 205, thereby facilitating the routing of the first wire 301 connected to the temperature sensor 300, and also facilitating the maintenance or replacement of the temperature sensor 300.

In this embodiment, the cavity 207 is provided, which can not only save materials, but also make the radio frequency electrode assembly lighter, thereby making the radio frequency handle 10 lighter and more convenient to use. The mounting hole 206 is provided on the side of the cavity 207 away from the connecting portion 201, thereby not only making it easier to install the temperature sensor 300, but also making the temperature sensor 300 closer to the contact area between the probe 202 and the skin, thereby making temperature monitoring more accurate. The mounting hole 206 is set as a blind hole. For example, the distance between the side of the mounting hole 206 away from the cavity 207 and the side of the probe 202 away from the connecting portion 201 can be approximately equal to 1.5 mm. In this way, not only can the temperature sensor 300 be prevented from being exposed to the outside and damaged, but also compared with directly opening the mounting hole 206 on the surface of the probe 202 away from the connecting portion 201, the mounting hole 206 of the utility model will not damage the surface of the probe 202 away from the connecting portion 201, and will not affect the generation of radio frequency signals by the probe 202, so that the cosmetic treatment effect of the probe 202 is better.

[0045] In some embodiments of the utility model, thermal conductive silicone grease is filled between the outer peripheral wall of the temperature sensor 300 and the hole wall of the mounting hole 206. In order to make the temperature sensor 300 more convenient to install, there will be a gap between the outer peripheral wall of the temperature sensor 300 and the hole wall of the mounting hole 206, which will affect the detection result of the temperature sensor 300. In this embodiment, thermal conductive silicone grease is filled between the outer peripheral wall of the temperature sensor 300 and the hole wall of the mounting hole 206. The thermal conductive silicone grease can quickly and evenly transfer the heat on the probe 202 to the temperature sensor 300, so that the temperature sensor 300 can detect the temperature more accurately.

For example, the outer peripheral wall of the probe 202 can be provided with a first sealing groove, the first sealing groove extends along the circumference of the probe 202, and the first sealing ring 208 can be installed in the first sealing groove. In this embodiment, the first sealing ring 208 is provided between the outer peripheral wall of the probe 202 and the hole wall of the clearance hole 101, so as to seal the gap between the probe 202 and the housing 100, and prevent external water or dust from entering the housing 100.

[0047] It should be noted that the first sealing groove can also be provided on the inner peripheral wall of the housing 100, or both the outer peripheral wall of the probe 202 and the inner peripheral wall of the housing 100 are provided with the first sealing groove.

The side of the thermoelectric cooler 405 close to the cooling box 401 dissipates heat, and the side of the thermoelectric cooler 405 close to the connecting portion 201 absorbs heat. For example, both the inlet 403 and the outlet 404 can be connected to a cooling medium box body (such as a water tank, etc.) in the beauty instrument body 20 through a medium delivery pipe. The cooling medium box body delivers the cooling medium into the cooling channel 402 through the inlet 403. After the end of the thermoelectric cooler 405 close to the connecting portion 201 absorbs the heat generated by the radio frequency electrode 200, the absorbed heat is dissipated through the side of the thermoelectric cooler 405 close to the cooling box 401 and transferred to the cooling medium in the cooling channel 402. The cooling medium after absorbing heat returns to the cooling medium box body through the outlet 404, thereby completing the cooling and heat dissipation of the radio frequency electrode 200.

[0049] In this embodiment, heat dissipation is carried out by the cooperation of the cooling box 401 through which the cooling medium flows and the thermoelectric cooler 405. The thermoelectric cooler 405 can quickly absorb the heat generated by the radio frequency electrode 200 and dissipate heat from the side close to the cooling box 401, and then gradually absorb heat through the cooling medium, and the heat dissipation and cooling effect is good.
