Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a radio frequency device. Background Technology

[0002] During treatment, radiofrequency devices emit radiofrequency energy to the human body through conductive electrode points. The temperature generated by the conductive electrode points during this process can cause a burning sensation, resulting in a poor user experience. However, traditional radiofrequency devices generally lack a cooling mode. Even if some radiofrequency devices have a cooling mode, only a few of the conductive electrode points of the radiofrequency device are in contact with the cooling structure, resulting in a small contact area between the conductive electrode points and the cooling structure. Therefore, there are problems with slow cooling speed and short cooling time. Utility Model Content

[0003] The purpose of this utility model is to solve the problems that existing radio frequency instruments generally do not have a cooling mode, and that some radio frequency instruments with a cooling mode have short cooling time and slow cooling speed, and to propose a radio frequency instrument.

[0004] To achieve the above objectives, this utility model employs the following technology: a radio frequency device, comprising:

[0005] The fuselage unit includes a separable bottom shell and a front shell. A main PCB board and a battery for power supply are installed in the fuselage cavity formed between the bottom shell and the front shell. A button assembly is provided on the front shell.

[0006] The functional head unit includes a housing that is detachably connected to the faceplate. Electrodes extending to the outside of the housing are provided on the housing via a functional head PCB board. A cooling component is also assembled inside the housing. The radio frequency instrument increases the cooling speed and cooling time by increasing the contact area between the electrodes and the cooling component.

[0007] The cooling component includes a TEC cooling chip and a heat sink disposed inside the housing, and thermally conductive silicone is attached to the TEC cooling chip.

[0008] The cooling assembly also includes a heat dissipation liner a and a heat dissipation liner b for the TEC cooling chip, wherein the heat dissipation liner a is located inside the bottom shell and the heat dissipation liner b is located inside the top shell.

[0009] The number of electrodes is several, and each electrode is in contact with thermally conductive silicone.

[0010] As a further description of the above technical solution: the outer shell is provided with a soft rubber pad for electrode head protection.

[0011] As a further description of the above technical solution: a light guide sheet and a lens that cooperates with the light guide sheet are provided on the outer shell;

[0012] The faceplate is equipped with a breathing light guide.

[0013] As a further description of the above technical solution: the button assembly includes a plurality of buttons mounted on the front shell via button sleeves, and a button PCB board mounted inside the front shell.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] By setting up a TEC cooling chip and thermally conductive silicone, each electrode on the RF instrument can contact the thermally conductive silicone, optimizing the contact area between the electrode and the cooling chip, and increasing the heat dissipation components to increase the cooling contact area of ​​the RF instrument, thereby improving the cooling speed and cooling time.

[0016] When multiple electrodes cool simultaneously, each electrode can store cold energy. In addition, the heat dissipation system efficiently removes heat from the hot end, preventing the cooling element from becoming inefficient due to excessive temperature. This greatly extends the cooling time, making it suitable for scenarios requiring prolonged cold compresses (such as post-medical aesthetic care). Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-2This embodiment provides an RF device, including a body unit and a functional head unit. The body unit includes a detachably connected bottom shell 19 and a front shell 14. A main PCB board 16 and a battery 17 for power supply are installed in the body cavity formed between the bottom shell 19 and the front shell 14. A button assembly is provided on the front shell 14. The button assembly includes a plurality of buttons 12 disposed on the front shell 14 through button sleeves 13, and a button PCB board 10 disposed inside the front shell 14. The functional head unit includes a shell 1 detachably connected to the front shell 14. Electrodes 4 extending to the outside of the shell 1 are provided on the shell 1 through the functional head PCB board 6.

[0023] In this invention, the bottom shell 19 and the front shell 14 form a cavity for the body, fixing the main PCB board 16 and the battery 17 to ensure stable operation of the circuit components and provide mechanical protection. The battery 17 powers the entire machine. The outer shell 1 is detachably connected to the front shell 14 for easy replacement or maintenance. The functional head PCB board 6 acts as a circuit intermediary, receiving the current signal from the main PCB board 16 and transmitting it to the electrode 4. The main PCB board 16 controls the transmission of the current signal. The button assembly receives user operation commands. When the user presses the button 12, the button 12 moves downward through the guide structure of the button sleeve 13, squeezing the contacts on the button PCB board 10, making the originally disconnected circuit open. The current is conducted through the main PCB board 16 to the functional head PCB board 6, driving the electrode 4 to output radio frequency energy and realize the treatment function.

[0024] Specifically, a cooling component is also installed inside the outer casing 1. The radio frequency instrument increases the contact area between the electrodes 4 and the cooling component to improve the cooling speed and cooling time. The cooling component includes a TEC cooling chip 8 and a heat sink 9 disposed inside the outer casing 1. Thermally conductive silicone 7 is attached to the TEC cooling chip 8. The cooling component also includes a heat dissipation liner a11 and a heat dissipation liner b18 for heat dissipation of the TEC cooling chip 8. The heat dissipation liner a11 is located inside the bottom shell 19, and the heat dissipation liner b18 is located inside the front shell 14. There are several electrodes 4, and each electrode 4 is in contact with the thermally conductive silicone 7.

[0025] When a direct current passes through the P-type and N-type semiconductor thermocouples of the TEC cooling chip 8, the directional movement of electrons will absorb heat at one end (forming a cold end) and release heat at the other end (forming a hot end). The electrode 4 is tightly attached to the cold end of the TEC cooling chip 8 through the thermally conductive silicone 7, realizing the conduction of cold energy to the skin. The hot end of the TEC cooling chip 8 is attached to the heat sink 9, which quickly conducts heat to the external heat dissipation structure. The heat dissipation liner a11 is located inside the bottom shell 19 and is in contact with the heat sink 9, further absorbing the heat from the hot end. The heat dissipation liner b18 is located inside the front shell 14. Through the air flow or structural design of the body cavity, the heat dissipation liner a11 is assisted to form a heat dissipation path that runs through the body, accelerating the dissipation of heat to the outside.

[0026] Since multiple electrodes 4 (8) are in contact with the thermally conductive silicone 7 of the TEC cooling chip 8, the contact area between the electrodes 4 and the cooling chip is optimized, and the heat dissipation component is increased to increase the cooling contact area of ​​the radio frequency device, thereby improving the cooling speed and cooling time. When multiple electrodes 4 (8) are cooling at the same time, each electrode 4 can store cold energy. In addition, the heat dissipation system efficiently dissipates the heat from the hot end, avoiding the cooling chip from becoming inefficient due to excessive temperature, thus greatly extending the cooling state duration. It is suitable for scenarios that require long-term cold compresses (such as post-medical aesthetic care).

[0027] It should be noted that the outer casing 1 is provided with a soft rubber pad 3 for protecting the electrode 4. The soft rubber pad 3 is made of elastic material (such as silicone or rubber) and can buffer the impact or pressure on the electrode 4 during the use or storage of the radio frequency instrument, so as to prevent the electrode 4 from being deformed, broken or worn due to external force, and extend the service life of the electrode 4.

[0028] The outer shell 1 is provided with a light guide sheet 5 and a lens 2 that cooperates with the light guide sheet 5, and the face shell 14 is provided with a breathing light guide component 15. The light guide sheet 5 and the lens 2 realize functional indication or auxiliary treatment through optical transmission, and the breathing light guide component 15 enhances the interactive experience with dynamic light effects.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
