Description

Technical Field

[0001] This invention relates to the field of beauty equipment technology, specifically to a cooling radiofrequency therapy device and equipment. Background Technology

[0002] Currently, bipolar radiofrequency treatment heads are widely used in the field of cosmetic anti-aging. According to Chinese patent CN206102733U, the radiofrequency treatment device includes: a controller, a radiofrequency generator, a temperature sensor, and a needle knife; the radiofrequency generator and controller are electrically connected. To prevent epidermal burns and improve treatment comfort, the following cooling methods are typically used:

[0003] Contact cooling: A semiconductor cooling chip is integrated inside the treatment head to indirectly cool the skin via metal electrodes or heat-conducting blocks. Disadvantages: Slow thermal response, uneven cooling, and potential condensation on the electrode surface, affecting radiofrequency energy conduction.

[0004] Cold spray: A cooling agent is sprayed onto the skin before, during, and after treatment. Disadvantages: The cooling depth is shallow, acting only on the epidermis, and it may interfere with the coupling and movement of the treatment head.

[0005] Circulating liquid cooling: Liquid flow channels are designed inside the electrodes. Disadvantages: Complex structure, risk of leakage, and increased size and weight of the treatment head.

[0006] In summary, all of the above cooling methods have shortcomings in terms of cooling efficiency, accuracy, safety, or structural complexity.

[0007] In traditional bipolar radiofrequency treatment, the current density is highest at the edges of the two electrodes (plates), resulting in the most intense heating in the area directly beneath the electrodes. The central area between the electrodes, however, relies primarily on heat conduction for heating, leading to a relatively delayed and uneven heating process. This uneven heating can affect the consistency of overall therapeutic efficacy. While current technologies focus on cooling the electrodes, there is a lack of solutions for direct, active thermal management of the skin in the area between the electrodes. Summary of the Invention

[0008] The purpose of this invention is to provide a cooling radiofrequency therapy device and apparatus to solve the problems existing in the prior art.

[0009] The objective of this invention is achieved as follows: a cooling radiofrequency therapy device, wherein the treatment side is fixed with:

[0010] Two electrodes electrically connected to the radio frequency circuit that drive the skin to heat up during radio frequency treatment;

[0011] An aluminum nitride ceramic sheet for cooling the skin is positioned between two electrode plates with a gap between it and the two electrode plates. The working surface of the aluminum nitride ceramic sheet and the working surface of the electrode plates are on the same plane, together forming a treatment surface that contacts the skin.

[0012] Furthermore, an insulating isolation seat is fixed to the treatment side of the therapeutic device, and the electrode plate and aluminum nitride ceramic sheet are fixed to the outside of the insulating isolation seat.

[0013] Furthermore, it also includes:

[0014] The handle body shell, with the insulating isolation seat fixed to one side of the handle body shell;

[0015] The middle cover is fixed to the other side of the handle body shell.

[0016] Furthermore, the insulating isolation seat is provided with two electrode positioning grooves and a ceramic plate positioning groove. The two electrode plates are respectively fixed in the two electrode positioning grooves, and the aluminum nitride ceramic plate is fixed in the ceramic plate positioning groove. The ceramic plate positioning groove and the electrode positioning groove are independent of each other.

[0017] Furthermore, it also includes a connecting cable, the middle cover has a cable insertion port, the electrode plate is electrically connected to an electrode connection terminal, the connecting cable passes through the cable insertion port into the handle body shell, and the electrode plate is connected to the connecting cable through the electrode connection terminal to electrically connect to the radio frequency circuit.

[0018] Furthermore, the handle body shell, the middle cover, and the insulating isolation seat are all made of engineering plastics.

[0019] Furthermore, it also includes a handle cover, which is fixedly connected to and covers the middle cover.

[0020] Furthermore, the area of ​​the working surface of the aluminum nitride ceramic sheet is larger than the area of ​​the working surface of the electrode plate.

[0021] As another aspect of the present invention, a radiofrequency therapy device is proposed, which includes a radiofrequency circuit and the radiofrequency therapy device described above.

[0022] The device also includes a temperature probe for real-time detection of skin temperature, which is connected to the radiofrequency therapy device.

[0023] The beneficial effects of this invention are as follows:

[0024] The aluminum nitride ceramic plate provides a unique cooling mode, which significantly improves the thermal management effect of the treatment device. During or after radiofrequency energy emission, the aluminum nitride ceramic plate directly removes heat from the skin between the electrodes, providing a cooling depth and efficiency far exceeding that of traditional air cooling or cold spray, and eliminating the need for a complex cooling structure, thus significantly reducing costs.

[0025] During radiofrequency treatment, the skin beneath the two electrodes rapidly heats up. Due to the extremely high thermal conductivity of the aluminum nitride ceramic sheet and its unique arrangement with the two electrodes, the aluminum nitride ceramic sheet can quickly absorb and conduct heat laterally from beneath the electrodes to its central area. This effectively reduces hot spots directly beneath the electrodes while simultaneously raising the temperature in the central area, resulting in uniform heating of the entire treatment area. This avoids localized overheating, improves treatment comfort and safety, and ensures consistent therapeutic efficacy. Attached Figure Description

[0027] Figure 2 This is a schematic diagram of the treatment side of the present invention.

[0028] Figure 3 This is an exploded view of the present invention. Detailed Implementation

[0029] The following will refer to the appendices in the embodiments of the present invention. Figure 1-3 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] In traditional bipolar radiofrequency therapy, the current density is between the two electrodes ( Figure 1 The edge of electrode 2) is the highest point, resulting in the most intense heating in the area directly beneath the electrode. The central area between the two electrodes relies primarily on heat conduction for heating, leading to a relatively delayed and uneven heating process. This uneven heating may affect the consistency of the overall therapeutic effect. While current technologies focus on cooling the electrodes, there is a lack of solutions for direct, active thermal management of the skin in the area between the electrodes.

[0031] like Figure 1-3 As shown, in order to solve the above problems, a radiofrequency therapy device based on aluminum nitride ceramic cooling is proposed, which includes a treatment head and a radiofrequency circuit electrically connected to the treatment head, and also includes a temperature probe 9 for real-time detection of skin temperature. The temperature probe 9 is connected to the treatment head and performs closed-loop control of the heating temperature, which effectively manages energy output and heat.

[0032] The treatment side of the treatment head is fixed with:

[0033] Two electrodes 2 are electrically connected to the radio frequency circuit and drive the skin to heat up during radio frequency treatment. The electrodes 2 are made of stainless steel and are respectively connected to the two poles of the radio frequency generator.

[0034] An aluminum nitride ceramic plate 1 is used to cool the skin. The aluminum nitride ceramic plate 1 is not connected to any radio frequency circuit and is only used as a thermal management element. The aluminum nitride ceramic plate 1 is located between two electrode plates 2, with a gap between it and the two electrode plates 2. The working surface of the aluminum nitride ceramic plate 1 and the working surface of the electrode plate 2 are on the same plane, together forming the treatment surface that contacts the skin.

[0035] The working surface area of ​​the aluminum nitride ceramic sheet 1 is larger than that of the working surface area of ​​the electrode plate 2, thereby expanding the cooling surface and ensuring the cooling effect.

[0036] Aluminum nitride ceramics are ideal heat dissipation materials for electronic devices due to their excellent thermal conductivity (high thermal conductivity, approximately 170-200 W / (m·K)), high insulation, non-toxicity, and chemical stability.

[0037] The core objective of this treatment device is to safely, effectively, and comfortably deliver radiofrequency energy to the dermis and subcutaneous tissue of the skin, stimulating collagen regeneration and remodeling, thereby achieving the effects of firming, lifting, reducing wrinkles, and improving skin texture.

[0038] To achieve the above objectives, the skin beneath the two electrodes 2 rapidly heats up during radiofrequency treatment. Due to the extremely high thermal conductivity of the aluminum nitride ceramic sheet 1, it can quickly absorb and conduct the heat from beneath the electrodes 2 laterally to its central area, effectively reducing hot spots directly beneath the electrodes while simultaneously increasing the temperature of the central area. This results in uniform heating of the entire treatment area, preventing local overheating, improving treatment comfort and safety, and ensuring consistent therapeutic efficacy.

[0039] In a preferred embodiment, an insulating isolation seat 3 (insulating frame) is detachably fixed to the treatment side of the treatment head. The "three elements" are two electrode plates 2 and an aluminum nitride ceramic sheet 1. The electrode plates 2 and the aluminum nitride ceramic sheet 1 are fixed to the outside of the insulating isolation seat 3 to form a detachable assembly of "insulating frame + three elements".

[0040] The treatment head also includes:

[0041] The handle body shell 6 and the insulating isolation seat 3 are detachably fixed to one side of the handle body shell 6, and the temperature probe 9 can be connected to the handle body shell 6;

[0042] The middle cover 5 is fixed to the other side of the handle body shell 6;

[0043] The connecting cable 7, the middle cover 5 has a cable insertion port 5a, the electrode plate 2 is electrically connected to the electrode connection terminal 8, the connecting cable 7 passes through the cable insertion port 5a into the handle body shell 6, and the electrode plate 2 is connected to the connecting cable 7 through the electrode connection terminal 8 to electrically connect to the radio frequency circuit.

[0044] Handle cover 4, handle cover 4 is fixedly connected to and covers the middle cover 5.

[0045] The handle body shell 6, the middle cover 5, and the insulating isolation seat 3 are all made of engineering plastics.

[0046] To facilitate the positioning and fixing of the aluminum nitride ceramic sheet 1 and the electrode plate 2, the insulating isolation base 3 is provided with two electrode positioning grooves 302 and one ceramic sheet positioning groove 301. The two electrode plates 2 are respectively fixed in the two electrode positioning grooves 302, and the aluminum nitride ceramic sheet 1 is fixed in the ceramic sheet positioning groove 301. The ceramic sheet positioning groove 301 and the electrode positioning groove 302 are independent of each other. The insulating isolation base 3 can ensure that the working surfaces of the aluminum nitride ceramic sheet 1 and the electrode plate 2 are flat and coplanar, and the sides are tightly wrapped with insulating material, eliminating any risk of electrical short circuit.
