[0052] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0053] Combination Figure 1 and Figure 2 This utility model provides a radio frequency (RF) beauty device 10, specifically including an RF circuit module 100, a treatment handpiece 200, a device housing 300, and a connecting cable 400. The RF circuit module 100 transmits RF energy to the treatment handpiece 200 via the connecting cable 400. The device housing 300 has an internal space for accommodating the RF circuit module 100 and is made of metal. One end of the connecting cable 400 is electrically connected to the RF circuit module 100, and the other end passes through the wall 310 of the device housing 300 and is electrically connected to the treatment handpiece 200 located outside the device housing 300, thus achieving the purpose of transmitting RF energy.

[0054] This structural design uses a metal housing 300 to house the radio frequency circuit module 100. The housing 300 serves as a fully enclosed metal cavity to seal the circuit portion of the radio frequency circuit module 100, creating an electric cage that shields the radio frequency signals generated by the module, thus preventing radiation damage to operators and treatment personnel.

[0055] Meanwhile, the radio frequency energy of the radio frequency circuit module 100 product inside the device shell 300 is transmitted to the external treatment handle 200 by setting the connecting cable 400 and passing through the wall surface 310 of the device shell 300, so as to meet the treatment needs of the treatment handle 200. In addition, the device shell 300 is made of metal material, and it is also convenient to process threads on the wall surface 310 of the device shell 300 for mounting other parts of the radio frequency beauty equipment 10. Compared with the scheme of forming the device shell 300 by using other materials such as plastic, the use of nut locking devices can be effectively reduced, the overall appearance is better, the strength is obviously stronger than plastic, and the durability is better.

[0056] As shown in Figure 1 and Figure 2 shown, in order to realize the purpose of passing through the device shell 300 made of metal, the connecting cable 400 includes a mainboard connecting line 410, a connector 420 and a handle cable 430 in sequence along the direction from the radio frequency circuit module 100 to the treatment handle 200. Among them, the connector 420 is arranged through the wall surface 310 of the device shell 300, the two ends of the mainboard connecting line 410 are respectively connected with the radio frequency circuit module 100 and the connector 420, and the two ends of the handle cable 430 are respectively connected with the treatment handle 200 and the connector 420. By arranging the connector 420 on the wall surface 310 of the device shell 300, the connecting cable 400 passes through the shell and is electrically connected with the treatment handle 200, realizes the transmission of radio frequency energy, and meets the treatment needs. Of course, the structure of the connecting cable 400 in the embodiment is only one preferred embodiment, and in other embodiments, the connecting cable 400 can also adopt the mode of passing through the device shell 300 from the whole cable to realize the electrical connection between the radio frequency circuit module 100 and the treatment handle 200, and realize the purpose of transmitting radio frequency energy.

[0057] Specifically, in the embodiment, the mainboard connecting line 410 is connected with the connector 420 in the receptacle 111 in the accommodating space. By connecting the mainboard connecting line 410 with the connector 420 through the receptacle 111 of the mainboard 110 of the radio frequency circuit module 100, it is convenient for disassembly and maintenance of the device.

[0058] As shown in Figure 2As shown, in the embodiment, the radio frequency beauty device 10 further comprises a module support 500, which is arranged in the accommodating space and connected to the wall surface 310 of the device shell 300. The radio frequency circuit module 100 is connected to the module support 500, and there is a gap between the radio frequency circuit module 100 and the wall surface 310 of the device shell 300. By arranging the module support 500 in the accommodating space inside the device shell 300 for the radio frequency circuit module 100 to be arranged, the degree of vibration generated during the movement of the radio frequency beauty device 10 being transmitted to the radio frequency circuit module 100 can be reduced through indirect connection, thereby protecting the important components inside the radio frequency beauty device 10 and improving the use durability of the radio frequency beauty device 10.

[0059] From Figure 2 As can be seen, in the embodiment, the radio frequency beauty device 10 further comprises a conductive sponge 600, which is filled in the gap between the radio frequency circuit module 100 and the wall surface 310 of the device shell 300. The conductive sponge 600 has good electrical conductivity and electromagnetic wave shielding performance. By filling the conductive sponge 600 between the radio frequency circuit module 100 and the wall surface 310 of the device shell 300, the electromagnetic radiation generated by the radio frequency circuit module 100 inside the device can be shielded. Therefore, this structure arrangement scheme can further reduce the interference to the surrounding environment, other devices and users. At the same time, the conductive sponge 600 can also protect the internal circuit from external electromagnetic fields and improve the overall anti-interference ability of the device.

[0060] In addition, the module support 500 in the embodiment comprises a mounting flat portion 510 and connecting portions 520 located at both ends of the mounting flat portion 510, the mounting flat portion 510 is used for mounting the radio frequency circuit module 100, and the connecting portions 520 extend towards the wall surface 310 of the device shell 300 and are connected to the wall surface 310 of the device shell 300. Specifically, the module support 500 is in a similar "Ω" shape, and the connecting portions 520 on both sides extend towards the wall surface 310 of the shell in a symmetrical manner. The module support 500 extends and connects to the wall surface 310 of the device shell 300 through the connecting portions 520 at both ends of the mounting flat portion 510, so that a gap can be formed between the radio frequency circuit module 100 and the wall surface 310 of the device shell 300.

[0061] From Figure 2It can also be seen that the RF power amplifier 120 of the RF circuit module 100 is mounted on the side of the mounting plane 510 near the wall 310 of the device housing 300, while the motherboard 110 of the RF circuit module 100 is mounted on the side of the mounting plane 510 away from the wall 310 of the device housing 300. The motherboard 110 is the core component of the RF circuit module 100, containing complex circuits and sensitive elements. In this embodiment, by mounting it on the side away from the RF power amplifier 120, electromagnetic interference from RF signals to the circuitry of the motherboard 110 can be reduced.

[0062] In this embodiment, the outer casing 300 of the radio frequency beauty device 10 is specifically formed by assembling multiple metal plates. This method of forming the casing by assembling multiple metal plates facilitates processing and manufacturing, thereby reducing component costs.

[0063] Specifically, in this embodiment, the joints of the metal plates have connection gaps, and the equipment housing 300 also includes conductive rubber (not shown in the figure). By filling the connection gaps with conductive rubber, on the one hand, flexible contact between the metal plates is achieved through conductive rubber, improving the sealing performance between the metal plates; on the other hand, conductivity between the metal plates is achieved through conductive rubber, improving the shielding performance of the equipment housing 300.

[0064] like Figure 3 and Figure 4 As shown, in the radio frequency beauty device 10 of this embodiment, some of the metal plates have a U-shaped cross-section, for example... Figure 3 The metal sheet located on the front of the equipment housing 300. The equipment housing 300 is formed by using a U-shaped metal sheet. This is because the U-shaped metal sheet is easy to process and shape, improving the installation accuracy during the enclosure process. Also, the U-shaped metal sheet can form at least three sides of the equipment housing 300, thereby reducing the number of metal sheets required to form the equipment housing 300.
