Description

Technical Field

[0001] This utility model discloses an RF beauty device, particularly an RF beauty device with an automatic massage function, belonging to the technical field of beauty instrument equipment. Background Technology

[0002] RF beauty devices release high-frequency alternating current through electrode heads, generating controllable electromagnetic waves that penetrate the epidermis to reach the dermis and subcutaneous tissue. This heats collagen fibers and the fat layer to achieve anti-wrinkle and firming effects, reduce fine lines and nasolabial folds, and lift the jawline. It can also improve skin laxity and promote absorption, especially since heating opens pores, increasing the penetration rate of skincare products. Some devices can even help reduce fat accumulation. RF beauty devices primarily utilize the temperature effect; when heated to 40-45℃, collagen fibers contract, producing an immediate firming effect. The heat promotes the regeneration of collagen and elastin, and continued use can improve skin elasticity.

[0003] Because RF beauty devices generate heat during use, current RF beauty devices on the market require the application of gel and manual movement of the device head on the skin surface.

[0004] Because radiofrequency energy can cause burns due to excessive heat when concentrated in the epidermis during the use of RF beauty devices, moving the device around can reduce this risk by dispersing the heat. Low-frequency devices (1MHz-3MHz) have limited penetration depth, so dynamic movements such as lifting and circular motions are necessary to reduce localized high temperatures. Dermal collagen requires continuous heating to activate (approximately 2-3 seconds per area). Moving the device after a short pause avoids overheating the epidermis while ensuring sufficient heating of deeper tissues. Moving the device too quickly or pausing for too long can lead to uneven energy distribution, affecting the firming effect. Certain techniques are required to achieve the desired results. Furthermore, the planar radiofrequency head must be moved close to the skin to ensure even energy distribution to every inch of skin, avoiding missed areas.

[0005] Due to structural limitations, current RF beauty devices generally have the following drawbacks: (1) Different ranges and frequencies of movement will affect the effect and experience of use, and certain experience is required to use them correctly; (2) Constant movement will increase the burden on the hands and pose a risk of burns.

The massage heads 21 are directly or indirectly electrically connected to the control board 7. The RF radio frequency energy output by the control board 7 is conducted to the massage heads 21 and output to the user through the massage heads 21.

[0029] In this embodiment, a rotating shaft 5 is fixedly installed on the rotor of the motor 6, and a guide head 2 is fixedly installed on the rotating shaft 5. The motor 6 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the guide head 2 to rotate.

[0030] In this embodiment, one or more annularly distributed conductive rings 51 are provided on the outer side of the rotating shaft 5. The conductive rings 51 are electrically connected to the massage head 21. A conductive carbon brush 4 is fixedly installed inside the outer shell 1 at the position corresponding to the conductive rings 51. The conductive carbon brush 4 is electrically connected to the control board 7. The RF radio frequency energy output by the control board 7 can be transmitted to the massage head 21 through the conductive carbon brush 4 and the conductive rings 51.

[0031] In this embodiment, five conductive rings 51 and five conductive carbon brushes 4 are provided, respectively for the A and B poles of the RF output, and the C, D and E poles in the EMS. In specific implementation, the number of conductive rings 51 and conductive carbon brushes 4 can also be set according to actual needs.

[0032] In this embodiment, the massage head 21 and the conductive ring 51 are connected by wires. One massage head 21 can be connected to one conductive ring 51, or multiple massage heads 21 can be connected to the same conductive ring 51.

[0033] In this embodiment, the carbon brush 4 is an electrical connection structure. A specific structure is given as an example in this embodiment and the accompanying drawings. Other structures that can conduct energy from the control board 7 to the conductive ring 51 can also be defined as carbon brushes 4. Please refer to the accompanying drawings. Figure 5 and attached Figure 6 In this embodiment, the carbon brush 4 mainly includes a carbon brush shell 41, a carbon brush rod 42, and a spring 44. The carbon brush rod 42 is disposed inside the carbon brush shell 41, and the spring 44 is fitted on the carbon brush rod 42. One end of the carbon brush rod 42 is the carbon brush head 421. The spring 44 pushes the carbon brush head 421 to extend to the outside of the carbon brush shell 41 and contact the conductive ring 51. Due to the pushing force of the spring 44, the contact state between the carbon brush head 421 and the conductive ring 51 can be maintained. The other end of the carbon brush rod 42 is electrically connected to the control board 7 through a wire.

[0034] In this embodiment, a baffle 422 is fixedly provided on the carbon brush rod 42, which can block the carbon brush rod 42 and prevent it from being completely pushed out of the carbon brush housing 41. In this embodiment, a sleeve 43 is fitted on the carbon brush rod 42, and one end of the spring 44 abuts against the sleeve 43 and the other end abuts against the carbon brush rod 42. If the sleeve 43 is not provided, one end of the spring 44 abuts against the inner side wall of the carbon brush housing 41 and the other end abuts against the carbon brush rod 42.

[0035] In this embodiment, a carbon brush mounting base 3 is fixedly installed inside the outer shell 1, and a carbon brush cavity 31 is provided on the carbon brush mounting base 3, and the carbon brush 4 is disposed in the carbon brush cavity 31.

[0036] In this embodiment, the massage head 21 can be made of conductive materials suitable for contact with the human body, such as stainless steel, nickel-plated metal, gold, or silver, while the body of the guide head 2 is made of insulating material. In this embodiment, eight massage heads 21 are arranged in a ring on the guide head 2. Two massage heads are connected in parallel, serving as the radio frequency A electrode, and another two are connected in parallel, serving as the radio frequency B electrode. The remaining four massage heads are connected to three other conductive rings for EMS output. One massage head serves as the EMS C electrode, one as the EMS D electrode, and the last two as the EMS E electrodes. In specific implementations, the number of massage heads and the electrode connection method can be set according to actual needs. The massage head 21 consists of two electrodes: A (positive / active electrode) – the electrode that releases radio frequency energy, typically in contact with the skin and transmitting current; and B (negative / return electrode) – the electrode that receives the current, forming a closed circuit to ensure safe energy conduction. EMS (Electrical Muscle Stimulation) uses low-frequency current to simulate nerve signals, stimulating facial muscle contractions (similar to "passive exercise") to achieve a firming and lifting effect. The C and D electrodes of the EMS serve as the main stimulation electrodes 1 (positive / anode), capable of outputting currents of varying intensities to accommodate muscle groups with different levels of sensitivity. The E electrode serves as the common return electrode (negative / cathode), providing a current return path for the C and D electrodes to ensure a complete circuit. The electrode arrangement of the massage head 21 can be found in the appendix. Figure 7 , attached Figure 7 The document provides a specific arrangement method. In actual implementation, the number of massage heads 21 and the electrode arrangement method can be set according to the actual situation.

The control button 12 is electrically connected to the control board 7 and is used to control the operation of this utility model. In this embodiment, two buttons are used as an example, one of which is used as a switch button and the other as an adjustment button. In specific implementation, one or more buttons can be set according to the actual situation.
