[0001] This utility model relates to the field of beauty instrument technology, and in particular to a radio frequency electrode assembly and a desktop radio frequency skin treatment device. Background Technology

[0002] Desktop radiofrequency skin therapy devices generate radiofrequency signals through probes on radiofrequency electrodes on a radiofrequency handpiece. These signals act on human tissue, producing a thermal effect and thus achieving cosmetic treatment results. Existing radiofrequency handpieces have infrared temperature sensors in their housings to detect the temperature of the area where the probe contacts the skin, preventing burns from excessive heat. However, interference from moisturizing gels on the skin and the probe covering the skin can easily lead to inaccurate temperature measurements.

[0003] In addition, users generally require the use of dedicated probes, but in the existing technology, probes are usually welded or installed on the radio frequency electrodes inside the housing by fasteners, which makes it impossible to replace the probe, or requires the housing to be removed to replace the probe, which is cumbersome, time-consuming and labor-intensive.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following is for reference. Figures 1 to 7 This invention describes a radiofrequency electrode assembly and a desktop radiofrequency skin therapy device according to embodiments of the present invention.

[0021] refer to Figures 2 to 7 As shown, the radio frequency electrode assembly according to the first aspect of the present invention is applied to the radio frequency handle 10 of a desktop radio frequency skin therapy device. The radio frequency handle 10 is provided with a housing 100 for accommodating the radio frequency electrode assembly. The radio frequency electrode assembly includes a radio frequency electrode 200, a temperature sensor 300, and a heat dissipation module 400.

[0022] The housing 100 has a cavity, in which the radio frequency electrode 200 and the heat dissipation module 400 of the radio frequency electrode assembly can be disposed. The end of the housing 100 can be provided with a clearance hole. The end of the housing 100 away from the clearance hole can be connected to a pipeline 30. The other end of the pipeline 30 can be connected to the beauty device body 20. The pipeline 30 can include a protective sleeve. A cooling medium delivery pipe and multiple wires can be inserted inside the protective sleeve. The cooling medium delivery pipe is used to connect to the heat dissipation module 400. The desktop radio frequency skin treatment device controls the operation of the radio frequency electrode 200 through multiple wires.

[0023] The radio frequency electrode 200 includes a connecting portion 201 and a probe 202. The connecting portion 201 is provided with a stud 203, the outer peripheral wall of which has external threads. The probe 202 is provided with a corresponding threaded hole 205. The probe 202 is threadedly connected to the connecting portion 201 by the engagement of the external thread of the stud 203 and the internal thread of the threaded hole 205. The stud 203 is provided with a mounting hole 204, which can penetrate the stud 203 along its axial direction. The probe 202 is configured to pass through a clearance hole in the housing 100 and at least partially protrude from the housing 100. The portion of the probe 202 protruding from the housing 100 can be clamped and rotated by a wrench 700, thereby allowing the probe 202 to be unscrewed from the stud 203 and removed from the housing 100.

[0024] The temperature sensor 300 is disposed in the mounting hole 204 of the stud 203. The temperature sensor 300 can be a contact temperature sensor, such as a thermistor temperature sensor or a thermocouple temperature sensor. The temperature sensor 300 is connected to a first wire 301, which can pass through the mounting hole 204 and be used to connect to the beauty device body 20 to realize signal transmission between the temperature sensor 300 and the beauty device body 20.

[0025] The heat dissipation module 400 is connected to the connection part 201. The heat dissipation module 400 can be air-cooled or liquid-cooled to cool the radio frequency electrode 200. According to the radio frequency electrode assembly of this utility model, during use, the heat dissipation module 400 can absorb the heat from the contact area between the radio frequency electrode 200 and the human skin, thereby reducing the temperature of the contact area and preventing burns caused by excessive heat. The temperature sensor 300 can monitor the temperature of the contact area between the radio frequency electrode 200 and the human skin. Since the temperature sensor 300 is installed in the mounting hole 204 of the stud 203, and the stud 203 is located inside and attached to the probe 202, the temperature of the contact area between the radio frequency electrode 200 and the human skin can be directly detected through heat conduction when the probe 202 contacts the human skin, resulting in more accurate temperature monitoring. Furthermore, the probe 202 is threadedly connected to the connecting part 201, and at least partially extends out of the housing 100. This allows the probe 202 to be clamped and rotated using a wrench 700, facilitating easy disassembly and replacement of the probe 202 and improving the user experience. In addition, the temperature sensor 300 is installed in the mounting hole 204 of the stud 203. When the probe 202 rotates, the torque applied to the temperature sensor 300 can be reduced, thus preventing the connection between the temperature sensor 300 and the wire from breaking.

[0026] It should be noted that a PCB board 600 can also be provided inside the receiving cavity of the housing 100. The first wire 301 can be connected to the PCB board 600, and the wire between the RF handle 10 and the beauty device body 20 can also be connected to the PCB board 600. In addition, a wire can also be provided between the RF electrode 200 and the PCB board 600. In this way, the temperature signal between the temperature sensor 300 and the beauty device body 20 can be transmitted, and the RF signal between the RF electrode 200 and the beauty device body 20 can also be transmitted.

[0027] refer to Figure 5 and Figure 6As shown, in some embodiments of this utility model, the bottom end of the threaded hole 205 is formed with a receiving hole 206. The radio frequency electrode assembly also includes a sleeve 500. The sleeve 500 is inserted into the mounting hole 204 and is fixed to the stud 203 in the circumferential direction. One end of the sleeve 500 extends into the receiving hole 206 and fits against the inner wall of the receiving hole 206. The temperature sensor 300 is disposed in the sleeve 500.

[0028] In this embodiment, the sleeve 500 is inserted into the mounting hole 204 and fixed circumferentially relative to the stud 203. This prevents the sleeve 500 from rotating with the probe 202 during rotation. Since the temperature sensor 300 is located inside the sleeve 500, this also prevents the connection between the temperature sensor 300 and the wire from breaking due to the probe 202 rotating with it. Furthermore, a receiving hole 206 is formed at the bottom of the threaded hole 205. One end of the sleeve 500 extends into the receiving hole 206 and fits against the inner wall of the receiving hole 206. This facilitates heat transfer between the probe 202 and the temperature sensor 300, making the temperature monitoring by the temperature sensor 300 more accurate.

[0029] It should be noted that the sleeve 500 can be made of aluminum alloy, which has excellent thermal conductivity. Of course, the sleeve 500 can also be made of other suitable materials, which will not be elaborated here.

[0030] It is understandable that the sleeve 500 and the stud 203 are fixed relative to each other in the circumferential direction, but can move relative to each other in the axial direction of the stud 203.

[0031] refer to Figure 5 As shown, in some embodiments of this utility model, one of the stud 203 and the sleeve 500 is provided with a groove 207, and the other is provided with a locking block 501 that is engaged in the groove 207, so that the sleeve 500 and the stud 203 are fixed relative to each other in the circumferential direction. For example, the end of the stud 203 may be provided with a groove 207, and the outer peripheral wall of the sleeve 500 may be provided with a locking block 501. The locking block 501 is engaged in the groove 207, and the groove 207 restricts the movement of the locking block 501 in the circumferential direction of the stud 203, but allows the locking block 501 to move out in the axial direction of the stud 203.

[0032] In this way, the sleeve 500 and the stud 203 can be fixed relative to each other in the circumferential direction, thereby preventing the sleeve 500 and the temperature sensor 300 from rotating with the probe 202. In addition, the sleeve 500 is allowed to move relative to the stud 203 in the axial direction, which facilitates the installation and removal of the sleeve 500 and the temperature sensor 300.

[0033] refer to Figure 5 and Figure 6As shown, in some embodiments of this utility model, the outer peripheral wall of the sleeve 500 is formed with a stepped surface 502, the stepped surface 502 abuts against the end face of the stud 203, the locking block 501 is provided on the stepped surface 502, and the locking groove 207 is provided at the end of the stud 203. For example, the outer peripheral wall of the sleeve 500 may be formed with an annular flange, and the end face of the annular flange near the stud 203 may be formed with a stepped surface 502.

[0034] In this embodiment, the sleeve 500 abuts against the end face of the stud 203 via the stepped surface 502, which restricts the sleeve 500 from moving freely along the axial direction of the stud 203, making the sleeve 500 more securely installed. Furthermore, the locking block 501 is located on the stepped surface 502, and the locking groove 207 is located at the end of the stud 203, which facilitates processing and allows the locking block 501 to be easily engaged or disengaged from the locking groove 207.

[0035] In some embodiments of this invention, thermally conductive silicone grease is used to fill the space between the outer surface of the temperature sensor 300 and the inner surface of the sleeve 500. To facilitate the installation of the temperature sensor 300, a gap may exist between the outer peripheral wall of the temperature sensor 300 and the inner surface of the sleeve 500, which could affect the detection results of the temperature sensor 300. In this embodiment, thermally conductive silicone grease is used to fill the space between the outer peripheral wall of the temperature sensor 300 and the inner surface of the sleeve 500. The thermally conductive silicone grease can quickly and evenly transfer heat from the probe 202 to the temperature sensor 300, thereby making the temperature detection by the temperature sensor 300 more accurate.

[0036] refer to Figures 4 to 6 As shown, in some embodiments of this utility model, the outer peripheral wall of the portion of the probe 202 extending out of the housing 100 is provided with a skirt 208, which is used to fit against the outer surface of the housing 100. During skin treatment, a moisturizing gel is applied to the skin. The moisturizing gel can easily enter the housing 100 through the gap between the housing 100 and the probe 202, thus affecting the radiofrequency electrode 200.

[0037] In this embodiment, a skirt 208 is provided on the outer peripheral wall of the probe 202. The skirt 208 is used to fit against the outer surface of the housing 100, thereby covering the gap between the housing 100 and the probe 202. In this way, the amount of moisturizing gel entering the housing 100 can be effectively reduced.

[0038] refer to Figure 7As shown, in some embodiments of this utility model, the wrench 700 is a bottle opener suitable for opening bottles. The wrench 700 includes two handles 701 and a working part 702. The two ends of the working part 702 are respectively connected to the two handles 701. The working part 702 forms at least one arc-shaped clamp 703, and the inner peripheral wall of the at least one arc-shaped clamp 703 is adapted to the outer peripheral wall of the probe 202. For example, the working part 702 of the wrench 700 may form multiple arc-shaped clamps 703, and the inner peripheral wall of one of the arc-shaped clamps 703 may be adapted to the outer peripheral wall of the probe 202.

[0039] In this embodiment, the wrench 700 can be a common bottle opener, which is not only simple in structure and affordable, but also widely available and easy to purchase.

[0040] refer to Figure 6 As shown, in some embodiments of this utility model, the distance between the end of the temperature sensor 300 furthest from the connecting portion 201 and the end of the probe 202 furthest from the connecting portion 201 is less than or equal to 1.5 mm. In this embodiment, this setting makes the temperature detection of the temperature sensor 300 more accurate.

[0041] refer to Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the connecting part 201 is provided with a wiring groove 209 that communicates with the mounting hole 204, and the temperature sensor 300 is connected to a first wire 301, which passes through the wiring groove 209. In this embodiment, the wiring groove 209 that communicates with the mounting hole 204 in the connecting part 201 makes it more convenient for the first wire 301 connected to the temperature sensor 300 to be routed.

[0042] refer to Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the connecting part 201 is provided with a connecting hole 210, which is used for inserting a second wire for transmitting radio frequency signals. For example, the connecting hole 210 can be provided on one side wall of the connecting part 201, one end of the second wire can be provided with a terminal, which is inserted into the connecting hole 210, and the other end of the second wire can be connected to the PCB board 600 inside the housing 100. The second wire is used to transmit radio frequency signals. In this embodiment, providing a connecting hole 210 in the connecting part 201 makes it more convenient to connect the second wire to the radio frequency electrode 200.

[0043] refer to Figures 4 to 6As shown, in some embodiments of this utility model, the heat dissipation module 400 includes a cooling box 401 and a semiconductor refrigeration chip 405. The cooling box 401 is provided with a cooling channel 402, one end of which is provided with an inlet 403 and the other end with an outlet 404. The semiconductor refrigeration chip 405 is disposed between the cooling box 401 and the connecting part 201. The side of the semiconductor refrigeration chip 405 near the cooling box 401 dissipates heat, and the side of the semiconductor refrigeration chip 405 near the connecting part 201 absorbs heat. For example, both inlet 403 and outlet 404 can be connected to the cooling medium tank (such as a water tank) inside the beauty device body 20 through a medium delivery pipe. The cooling medium tank delivers cooling medium into the cooling channel 402 through inlet 403. After the end of the semiconductor cooling chip 405 near the connection part 201 absorbs the heat generated by the radio frequency electrode 200, the absorbed heat is dissipated through the side of the semiconductor cooling chip 405 near the cooling tank 401 and transferred to the cooling medium in the cooling channel 402. The cooling medium after absorbing heat returns to the cooling medium tank through outlet 404, thereby completing the cooling and heat dissipation of the radio frequency electrode 200.

[0044] In this embodiment, heat dissipation is achieved by the cooling box 401 through which the cooling medium flows and the semiconductor cooling chip 405 working together. The semiconductor cooling chip 405 can quickly absorb the heat generated by the radio frequency electrode 200 and dissipate heat from the side near the cooling box 401. Then, the heat is gradually absorbed through the cooling medium, resulting in good heat dissipation and cooling effect.

[0045] It should be noted that the cooling medium can be water, air, or other suitable cooling media. The heat dissipation module 400 can also have other structures, such as direct cooling through cooling water channels.

[0046] refer to Figure 6 As shown, in some embodiments of this utility model, insulating sheets 406 are respectively attached to both sides of the semiconductor cooling chip 405 in the thickness direction. The insulating sheets 406 can be made of electrically insulating materials such as ceramics. Attaching insulating sheets 406 to both sides of the semiconductor cooling chip 405 in the thickness direction can reduce leakage and short circuit phenomena, thus improving safety.

[0047] refer to Figure 4 and Figure 5As shown, in some embodiments of this utility model, the connecting part 201 is provided with a first mounting part 211, and the cooling box 401 is provided with a corresponding second mounting part 407. A connecting sleeve 408 is provided between the first mounting part 211 and the second mounting part 407, and the two ends of the connecting sleeve 408 are respectively connected to the first mounting part 211 and the second mounting part 407 by fasteners. For example, there may be two first mounting parts 211, which are respectively located on opposite sides of the connecting part 201, and there may be two second mounting parts 407, which are respectively located on opposite sides of the cooling box 401 corresponding to the first mounting parts 211. The first mounting part 211 and the second mounting part 407 are respectively provided with a first through hole and a second through hole. The first through hole is aligned with the connecting sleeve 408 and a fastener is installed thereon, and the second through hole is aligned with the connecting sleeve 408 and a fastener is installed thereon.

[0048] In this embodiment, the semiconductor cooling chip 405 and the insulating sheet 406 are clamped between the cooling box 401 and the connecting part 201 for installation and fixation, making installation more convenient. In addition, a connecting sleeve 408 is provided between the first mounting part 211 and the second mounting part 407, which makes the structure stronger and the connection more stable. It also facilitates the connection between the cooling box 401 and the connecting part 201, which have a large gap, making it more practical.

[0049] refer to Figures 4 to 6 As shown, in some embodiments of this utility model, the cooling box 401 includes a body part 409 and a cover 410. The body part 409 is provided with a cooling groove, and the cover 410 is detachably connected to the body part 409 and covers the cooling groove to form a cooling channel 402. A sealing ring 411 is provided between the body part 409 and the cover 410. For example, a cooling groove can be formed on the end face of the body part 409 away from the connecting part 201. The cover 410 and the body part 409 can be connected by fasteners, snap-fit, or other suitable means. The cover 410 covers the cooling groove, thereby enclosing and forming the cooling channel 402. An inlet 403 and an outlet 404 can both be provided on the cover 410. A sealing groove can be provided on the end face of the cover 410 near the body part 409. The sealing groove surrounds the outside of the cooling channel 402, and the sealing ring 411 can be installed in the sealing groove.

[0050] In this embodiment, the cooling box 401 adopts a split structure, which not only makes it easier to process the cooling channel 402, but also makes it easier to clean the cooling channel 402. In addition, a sealing ring 411 is provided between the main body 409 and the cover 410, which improves the sealing performance and effectively prevents the leakage of cooling medium.

[0051] It should be noted that the sealing ring 411 may also be provided on the end face of the main body 409 near the cover 410, or the end faces of the cover 410 and the main body 409 that are close to each other may both be provided with sealing grooves.

[0052] refer to Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the first mounting part 211 is also used to connect with the housing 100. For example, the first mounting part 211 can be connected to the housing 100 through multiple fasteners. In this embodiment, the connection part 201 is connected to the housing 100, which realizes the installation and fixation of the radio frequency electrode 200 and the heat dissipation module 400, which is convenient for installation. In addition, the connection position is close to the probe 202, which can reduce the vibration of the probe 202 during use, thereby making the cosmetic treatment effect of the probe 202 better. It should be noted that the first mounting part 211 and the housing 100 can also be connected by snap-fit, adhesive or other suitable methods.
