Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a beauty instrument handle. Background Art

[0002] Some beauty instrument technologies focus on providing non-invasive skin treatments to promote collagen production, enhance skin care product absorption, promote cell vitality, and tighten the skin. These devices usually include temperature control functions to ensure that the temperature on the skin remains stable and avoid overheating or overcooling, thereby improving the safety and comfort of treatment. Many existing beauty instruments rely on natural air cooling for heat dissipation, which has limited heat dissipation capacity. Especially when the device generates a lot of heat, the air cooling effect is not ideal and the device temperature cannot be quickly and effectively reduced. Due to the complex structure of some devices, it is difficult for the heat dissipation components to contact the heat source, or the heat dissipation path is too long, resulting in reduced heat dissipation efficiency.

[0013] A beauty instrument temperature control system is applied to the beauty instrument handle, comprising a control unit, a temperature signal acquisition unit, and a refrigeration unit, wherein the control unit is electrically connected to the temperature signal acquisition unit and the refrigeration unit.

[0014] Preferably, the control unit includes a circuit board and a controller installed on the circuit board; the temperature signal acquisition unit includes a plurality of temperature sensors, and the temperature sensors are electrically connected to the controller; the refrigeration unit includes a wind drive device, a first ventilation duct, a second ventilation duct, a heat dissipation component, a heat conductive sheet, and a refrigeration sheet, and the wind drive device is electrically connected to the controller.

[0015] The handheld part provided in the embodiment of the present application is applied, wherein the handheld part adopts an ergonomically optimized design, and its outer contour naturally fits the hand-holding action, and the surface material has good anti-slip and corrosion resistance, such as the use of high-strength engineering plastics with special texture treatment, which effectively improves the stability and comfort of user operation, reduces fatigue after long-term use, and ensures the durability of the equipment in various usage environments.

[0016] The connector provided by the embodiment of the present application is applied, wherein the transition between the inclined surface and the vertical surface of the connector adopts a smooth arc design, and the angle of the inclined surface is optimized by calculation and simulation, which can effectively disperse the stress concentration of the connection part while ensuring the convenient plugging and unplugging of the treatment head, and improve the stability and reliability of the mechanical structure. The power pin in the groove body at the lower part of the inclined surface is made of high-purity copper alloy, and the surface is gold-plated, which has excellent conductivity and oxidation resistance. Its arrangement spacing is optimized to ensure accurate docking with the electrode point of the treatment head and achieve stable and efficient electrical signal transmission. The inner wall of the air collecting duct in the first ventilation duct adopts a streamlined design, and optimizes the airflow direction according to the principle of aerodynamics to reduce wind resistance. The elastic button of the limit device is made of high-elastic rubber material, which is comfortable to touch and sensitive to feedback. The limit rod is made of high-strength aluminum alloy, and the surface is anodized to enhance wear resistance and corrosion resistance. The matching tolerance between it and the connecting board slot is controlled within a very small range, ensuring the firmness and position accuracy of the treatment head after installation, and effectively preventing the treatment head from loosening or falling off due to equipment vibration or accidental collision.

[0017] The treatment head provided by the embodiment of the present application is applied, wherein the shell is made of lightweight, high-strength aluminum alloy material, formed by precise CNC processing technology, and has good heat dissipation performance and electromagnetic shielding effect. The number, size and distribution position of the heat dissipation ports on both sides of the shell are optimized through simulation analysis and experimental verification, and the downward inclination angle of the air duct is 30°-45°, which ensures that the heat dissipation airflow is discharged smoothly while effectively preventing external dust and impurities from flowing back into the equipment, thereby ensuring the cleanliness and stable operation of the equipment. The second ventilation duct adopts a variable diameter design, and the gradual change curve of the pipe diameter from the air inlet to the air outlet is determined according to the principle of fluid mechanics, which increases the air flow rate while reducing the air flow noise. Its internal surface is smoothed to reduce air friction resistance and further improve the heat dissipation efficiency. The support plate is made of high-temperature resistant and high-strength engineering plastic material, and is integrally formed with the shell through a special injection molding process to ensure stable support and precise positioning of the heat dissipation component. The heat sink of the heat dissipation component is made of aluminum alloy material with high thermal conductivity, and the surface is finely processed with micro grooves to effectively increase the heat dissipation area and heat exchange efficiency. The spacing between the heat sinks is optimized to ensure sufficient ventilation space while preventing airflow turbulence, ensuring that heat can be dissipated quickly and evenly. The thermal conductive sheet is made of copper-based composite material, which has high thermal conductivity and good thermal stability, and can quickly transfer the heat generated by the treatment sheet to the heat dissipation component and the cooling sheet. The cooling sheet uses high-performance semiconductor cooling chips, whose cooling power, efficiency and temperature control accuracy have been strictly screened and tested. According to different treatment modes and skin temperature feedback, accurate and rapid cooling adjustment can be achieved, effectively protecting the skin from overheating damage. The treatment sheet is made of medical-grade stainless steel, and the surface is specially polished and antibacterial treated. The electrode points are inlaid and flush with the surface of the treatment sheet to ensure uniform distribution and stable conduction of the current, while avoiding scratches or stings on the skin. The protective film is made of highly permeable, soft and biocompatible silicone material with a thickness of 0.1-0.2mm, which can effectively isolate the treatment sheet from the skin to prevent cross infection and minimize the impact on the treatment energy transfer and temperature perception.

[0018] The temperature control system of the beauty instrument provided in the embodiment of the present application is applied, wherein the controller of the control unit adopts an intelligent chip, and has multiple preset treatment modes and temperature control algorithms built in, such as adaptive fuzzy control algorithm, PID temperature control algorithm, etc., which can automatically adjust the temperature control parameters according to the skin type, treatment part and usage habits of different users, and realize personalized and precise temperature management. At the same time, the controller has a complete fault diagnosis and alarm function, which can monitor the working status of each component of the equipment in real time, such as abnormal speed of the wind drive device, signal deviation of the temperature sensor, working failure of the refrigeration plate, etc., and promptly remind the user through sound and light alarm to ensure the safe and reliable operation of the equipment.

[0019] The temperature sensor of the temperature signal acquisition unit adopts a high-precision and high-sensitivity thermistor sensor, with a measurement accuracy of ±0.3°C and a response time of less than 0.5 seconds. The installation position of the sensor has been optimized and evenly distributed in the key parts of the treatment piece, which can accurately and real-time collect the temperature changes of the treatment area and transmit the temperature signal to the controller through a shielded cable to ensure the stability and anti-interference of the signal transmission.

[0020] The coordinated working mechanism of the various components of the refrigeration unit is further optimized. The wind drive device adopts a brushless DC motor, which has the advantages of high speed, low noise and long life. Its speed can be accurately adjusted within the range of 1000-5000rpm, forming a closed-loop control with the controller, and adjusting the wind speed in real time according to temperature feedback. The connection between the first ventilation duct and the second ventilation duct adopts a silicone sealing ring with good sealing performance to prevent air leakage and ensure stable airflow transmission. High-efficiency thermal conductive silicone grease is used to fill the heat dissipation component, the heat conductive plate and the cooling plate to reduce thermal resistance and improve heat conduction efficiency. The entire refrigeration unit can quickly and stably realize the cooling and heat dissipation functions under different ambient temperatures and treatment load conditions, ensuring that the temperature of the treatment head is always within a safe and effective treatment range.

[0021] Advantages of the present invention:

[0022] 1. The bottoms of multiple evenly arranged heat sinks are interconnected to form an efficient heat dissipation surface, which can quickly conduct and dissipate heat. In conjunction with the design of the heat dissipation port, not only the number, size and distribution position, but also the internal air duct is tilted downward by 30°-45°. This tilted design is based on the principles of aerodynamics, so that the heat dissipation airflow forms a natural downward guide when discharged, effectively preventing hot air from flowing back and ensuring that heat can be discharged from the device smoothly and quickly. During the long-term operation of the equipment, even if a large amount of heat is generated, the heat dissipation system can always control the internal temperature of the equipment within a safe range, effectively protecting the internal circuit board and other precision circuit components from high temperature damage, significantly extending the service life of the equipment, and reducing the risk of equipment failure due to overheating.

[0023] 2. The heat dissipation components work closely with the ventilation duct system. The air collecting duct in the first ventilation duct adopts a large diameter design, which can efficiently collect a large amount of airflow generated by the wind drive device, and then accurately guide the airflow to the second ventilation duct through the gradually changing diameter of the air jet duct. The variable diameter design of the air inlet of the second ventilation duct is smaller than the air outlet, which further accelerates the air flow rate, so that the air flow can more effectively take away the heat when passing through the heat dissipation components. The entire ventilation and heat dissipation system forms an efficient airflow circulation and heat dissipation channel, ensuring that the equipment can maintain a stable low-temperature operating environment under various working intensities, providing a solid guarantee for the continuous and reliable operation of the equipment.

[0024] 3. Temperature sensors play a key role in the temperature monitoring of the treatment head. Multiple high-precision temperature sensors are evenly distributed on the treatment piece, with a measurement accuracy of up to ±0.3℃, which can sense the temperature changes in the treatment area in real time and accurately. These sensors use thermistor technology, with an extremely short response time of less than 0.5 seconds, and can quickly transmit temperature data to the controller on the circuit board. The controller has built-in intelligent temperature control algorithms, such as a hybrid algorithm combining an adaptive fuzzy control algorithm with a PID temperature control algorithm. The algorithm can quickly and accurately determine whether the temperature deviates from the preset safety range based on the real-time data fed back by the temperature sensor. Once it is detected that the temperature is close to or exceeds the set upper limit threshold, the controller will immediately initiate a series of temperature adjustment measures. For example, it will accurately control the speed increase of the wind drive device and increase the ventilation volume to enhance the heat dissipation effect; at the same time, it will adjust the cooling power of the cooling piece as needed to quickly reduce the temperature of the treatment piece. Through this dynamic and precise temperature control mechanism, skin burns caused by excessive temperature during treatment are effectively prevented, greatly improving the safety of treatment, so that users do not need to worry about skin safety issues while enjoying beauty treatment.

[0025] 4. The detachable connection design between the treatment head and the handheld part brings great convenience to users and expands the function of the equipment. Its connection structure adopts an integrated design of mechanical locking and electrical connection. The connector and the connection plate of the treatment head are matched through an inclined surface and a vertical surface. The angle of the inclined surface is optimized to facilitate the plugging and unplugging of the treatment head. At the same time, the vertical surface ensures the stability of the connection. In terms of electrical connection, the power pin in the groove body at the lower part of the inclined surface of the connector is made of high-purity copper alloy and gold-plated, which has excellent conductivity and oxidation resistance. The arrangement spacing of the power pins is precisely matched with the electrode points in the treatment head, and a fast and stable electrical connection can be achieved when the treatment head is installed. At the same time, the limit devices on both sides of the connector adopt a combination design of elastic buttons and L-shaped limit rods. The elastic button is easy to operate and feels comfortable. When pressed, the limit rod can move up and down flexibly along the direction of the support column. The limit rods fit tightly with the slots on both sides of the connecting plate. The shape and size of the slots are carefully designed, and the tolerance is controlled within a very small range, ensuring that the position of the treatment head is accurate, firm and stable after installation, and effectively preventing the treatment head from falling off or moving due to accidental collision or vibration during use. This reliable detachable connection design allows users to easily replace the treatment head with corresponding functions according to different beauty treatment needs, such as skin tightening, soothing repair, deep cleaning, etc. Different treatment heads can integrate different technical modules, such as phototherapy modules with specific wavelengths, radio frequency modules with different energy levels, etc., which greatly increases the applicability and functional diversity of the equipment, meets the personalized needs of users at different beauty stages and different skin conditions, and enables the equipment to achieve one-stop multiple beauty treatment services.

[0026] 5. The design of the cooling sheet and protective film fully considers the user's comfort during the treatment process. The cooling sheet adopts high-performance semiconductor cooling chips, and its cooling power, efficiency and temperature control accuracy have been strictly screened and tested. During the treatment process, the cooling sheet can quickly and stably adjust the temperature of the treatment sheet according to the feedback of the temperature sensor and the preset treatment temperature requirements, so that it can be kept within a suitable low temperature range, effectively reducing the burning sensation and discomfort that may occur to the skin during beauty treatment. For example, during radio frequency skin tightening treatment, the radio frequency energy will increase the skin temperature. At this time, the cooling sheet will start the cooling function in time to maintain the skin surface temperature in an optimal temperature range that can promote collagen production without causing users to feel overheating and pain. The protective film is made of highly permeable, soft and biocompatible silicone material, and the thickness is precisely controlled at 0.1-0.2mm. This material can not only effectively isolate the treatment sheet from the skin to prevent cross infection, but also minimize the impact on treatment energy transmission and temperature perception. Its soft texture fits closely to the skin and does not cause extra friction or pressure to the skin during treatment, allowing users to experience a comfortable and gentle skin contact experience, improving users' acceptance and satisfaction with beauty treatments, and making the entire beauty treatment process more pleasant and relaxing.

[0037] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0039] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] Combined with Figure 1-9 As shown, a beauty instrument handle includes a handheld portion 1, wherein a circuit board 4 is disposed inside the handheld portion 1, and the circuit board 4 is used to control and connect various functions of the beauty instrument. The handheld portion 1 is detachably connected to a treatment head 2, and the treatment head 2 is used to directly act on the skin. A connector 7 is disposed inside the handheld portion 1, and a first ventilation duct 701 is disposed in the middle of the connector 7, and the first ventilation duct 701 is used for air circulation. A wind driving device 6 is disposed at the air inlet of the first ventilation duct 701; the wind driving device 6 (such as a fan) is used to generate wind to help dissipate heat.

[0041] The treatment head 2 is detachably connected to the handheld part 1 via a connector 7; this design allows the treatment head to be replaced according to different treatment requirements, thereby increasing the flexibility and applicability of the device.

[0042] The treatment head 2 includes a shell, and a second ventilation duct 202 is arranged in the shell. A connecting plate 201 is arranged on one side of the air inlet of the second ventilation duct 202, and a heat dissipation component 203 is arranged on the other side. The air inlet of the second ventilation duct 202 is connected to the air outlet of the first ventilation duct 701, forming an air circulation channel, which helps to dissipate heat and keep the device cool.

[0043] A heat conducting sheet 204, a cooling sheet 205, a treatment sheet 210, and a protective film 206 are sequentially arranged below the heat dissipation assembly 203; a plurality of temperature sensors 207 and a plurality of electrode points 208 are arranged on the treatment sheet 210; the circuit board 4 is respectively connected to the wind driving device 6, the temperature sensor 207, and the electrode points 208;

[0044] The temperature sensor 207 monitors the temperature of the treatment sheet 210 and transmits the data to the controller on the circuit board 4. The controller adjusts the operation of the wind drive device 6 according to the temperature data to control the temperature of the device. The circuit board 4 is connected to the electrode point 208, and the current is transmitted through the electrode point 208 to perform electrotherapy or other beauty treatments that require current. The cooling sheet 205 includes a transparent crystal cooling sheet, a ceramic substrate hot surface cooling sheet, a VC (Vapor Chambers) heat conducting plate, and an RC12-4-01LS semiconductor cooling sheet.

[0045] The above scheme has the following advantages: through temperature control and current transmission, the effect of beauty treatment can be improved, the cooling plate 205 and the protective film 206 can protect the skin from overheating, the heat dissipation component 203 and the heat conductive plate 204 help to dissipate heat, reduce equipment overheating, and improve the durability and service life of the equipment. The temperature sensor 207 can prevent the equipment from overheating and reduce the risk of burns. The detachable treatment head 2 can be replaced according to different treatment needs to provide more treatment options. Since the treatment head 2 can be detached, it is convenient for users to clean and maintain it, thereby maintaining the hygiene and performance of the equipment.

[0046] Furthermore, the side of the connector 7 in contact with the connecting plate 201 is an inclined surface, and the other side is a vertical surface. A first ventilation duct 701 is provided in the middle of the connector 7. A plurality of evenly arranged power pins 3 are provided in the groove body at the lower part of the inclined side of the connector 7. The power pins 3 are electrically connected to the electrode points 208 through the treatment head 2, wherein the power pins 3 are used to electrically connect the circuit board 4 of the handheld part 1 to the electrode points 208 of the treatment head 2. The electrical connection achieved through the power pins 3 can control the current transmitted to the electrode points 208, thereby achieving precise cosmetic treatment.

[0047] The connection member 7 is provided with a limit device 5 on both sides. The limit device 5 includes an elastic button and a limit rod, the limit rod is provided with an elastic button, and the limit rod is L-shaped and clamped with the connection plate 201. The limit device 5 ensures that the treatment head 2 is correctly installed and limits its movement, prevents the treatment head from being displaced or falling off during use, and ensures the stability of the connection. The connection plate 201 is provided with a card slot 209 on both sides, and the card slot 209 cooperates with the limit rod in the limit device.

[0048] The handheld part 1 and the treatment head 2 are connected to ensure electrical and mechanical connection between the two. The connecting plate 201 is located on one side of the treatment head 2 and cooperates with the connecting member 7 to achieve the connection between the treatment head and the handheld part.

[0049] The first ventilation duct 701 in the connecting member 7 includes an air collecting duct 7012 and an air spray duct 7011. The diameter of the air collecting duct 7012 is larger than that of the air spray duct 7011. The air inlet of the air collecting duct 7012 is connected to the wind driving device 6, the air outlet of the air collecting duct 7012 is connected to the air inlet of the air spray duct 7011, and the air inlet of the air spray duct 7011 is connected to the air inlet of the second duct 202.

[0050] The wind collecting duct 7012 is used to collect the wind generated by the wind driving device 6, and the air jet duct 7011 guides the wind collected by the wind collecting duct 7012 to the second ventilation duct 202 of the treatment head 2. The design of the wind collecting duct 7012 and the air jet duct 7011 enables the wind to be collected and distributed more effectively, thereby optimizing the utilization efficiency of the wind.

[0051] The working principle of the above scheme is as follows: the wind driving device 6 generates wind in the handheld part 1, and the generated wind enters through the air inlet of the air collecting duct 7012. Since the diameter of the air collecting duct 7012 is larger than that of the air jet duct 7011, it can collect more wind. The air outlet of the air collecting duct 7012 is connected to the air inlet of the air jet duct 7011, and the wind is distributed from the air collecting duct 7012 to the air jet duct 7011. The air jet duct 7011 transmits the wind from the connecting piece 7 to the second ventilation duct 202 of the treatment head 2. Through the second ventilation duct 202, the wind reaches the heat dissipation component 203, which helps to dissipate heat and keep the equipment cool.

[0052] The air inlet of the second ventilation duct 202 is smaller than the air outlet. This design helps to increase the air flow rate and improve the heat dissipation efficiency. Support plates are provided on both sides of the air outlet of the second ventilation duct 202. A heat dissipation component 203 is provided in the middle of the support plates. The support plates are used to fix and support the heat dissipation component 203. The air inlet end of the heat dissipation component 203 corresponds to the air outlet of the second ventilation duct 202. The heat dissipation component 203 includes a plurality of heat dissipation fins arranged uniformly in parallel. The bottoms of the heat dissipation fins are interconnected to form a heat dissipation surface. The channel formed between the heat dissipation fins is the air outlet. The top surface of the heat dissipation fin corresponds to the air outlet of the second ventilation duct 202.

[0053] The working process of the second ventilation duct 202 and the heat dissipation component 203: When the wind driving device 6 is working, air is sucked in through the first ventilation duct 701, and then enters the air inlet of the second ventilation duct 202 through the air outlet of the connecting member 7. The air flows through the second ventilation duct 202. Since the air inlet is smaller than the air outlet, the air flow rate increases, which helps to improve the heat dissipation efficiency. The air flows through the heat dissipation component 203. The design of the heat dissipation component 203 allows the air flow to effectively take away the heat. The air inlet end of the heat dissipation component 203 corresponds to the air outlet of the second ventilation duct 202, ensuring that the air flow directly passes through the heat sink, and the heat sink dissipates heat by conduction and convection.

[0054] The shell is provided with a plurality of evenly arranged heat dissipation openings 8 on both sides. The air ducts in the heat dissipation openings 8 are tilted downward. The heat dissipation openings correspond to the air outlets of the heat dissipation assembly 203 .

[0055] Working process of the present invention: when the beauty instrument is working, the wind driving device 6 generates wind in the handheld part 1, and transports air from the handheld part 1 to the second ventilation duct 202 of the treatment head 2 through the first ventilation duct 701. The heat generated by the treatment head 2 during operation is conducted to the cooling plate 205 through the heat conductive plate 204, and then transferred to the heat dissipation component 203 by the cooling plate 205. The heat sink design of the heat dissipation component 203 helps to dissipate heat. The channel formed between the heat sinks serves as an air outlet to discharge heat. The heat dissipation port 8 corresponds to the air outlet of the heat dissipation component 203. The air duct is tilted downward, so that the heat dissipated by the heat dissipation component 203 can be smoothly discharged through the heat dissipation port 8 to avoid accumulation inside the treatment head 2.

[0056] The present invention has the advantages that:

[0057] 11. Through the designed heat dissipation component 203 and heat dissipation port 8, as well as the inclined air duct design, efficient heat dissipation is achieved, protecting the internal circuit and the user's skin.

[0058] 12. The temperature sensor 207 and the circuit board 4 are used together to monitor and adjust the temperature of the treatment head in real time, prevent burns and overheating, and improve the safety of treatment.

[0059] 13. The detachable connection design between the treatment head 2 and the handheld part 1 makes it easy to replace the treatment head according to different treatment needs, thereby increasing the applicability and flexibility of the device.

[0060] 14. The design of the cooling sheet 205 and the protective film 206 can reduce the discomfort of the skin during the treatment process.

[0061] Improve user comfort.

[0062] A beauty instrument temperature control system, the beauty instrument handle, includes a control unit 10, a temperature signal acquisition unit 11, and a refrigeration unit 12, and the control unit 10 is electrically connected to the temperature signal acquisition unit 11 and the refrigeration unit 12.

[0064] 1. Start the beauty instrument: When the handle of the beauty instrument is started, the circuit board 4 and the controller 9 in the control unit 10 start working.

[0065] 2. Temperature monitoring: Several temperature sensors 207 in the temperature signal acquisition unit 11 start to monitor the temperature of the treatment head 2 . These sensors are distributed on the treatment sheet 210 .

[0066] 3. Data transmission: The temperature sensor 207 transmits the monitored temperature data to the controller 9 .

[0067] 4. Temperature control: The controller 9 determines whether the temperature needs to be adjusted based on the received temperature data. If the temperature is too high, the controller 9 will start or increase the running speed of the wind drive device 6 to enhance heat dissipation.

[0068] 5. Wind-driven: The wind-driven device 6 starts to work, and transmits air from the handheld part 1 to the treatment head 2 through the first ventilation duct 701 and the second ventilation duct 202 .

[0069] 6. Heat dissipation: Air flows through the heat dissipation component 203, the heat conductive sheet 204 and the cooling sheet 205 to help dissipate the heat generated by the treatment head 2.

[0070] 7. Temperature adjustment: If the temperature needs to be lowered, the controller 9 will adjust the working state of the refrigeration plate 205 to achieve rapid cooling.

[0071] 8. Continuous monitoring and adjustment: The controller 9 continuously monitors the data of the temperature sensor 207 and adjusts the wind driving device 6 and the cooling plate 205 in real time to keep the temperature of the treatment head 2 within a suitable range.

[0072] Among them, when the beauty instrument is started, the controller 9 first initializes the wind drive device 9 to ensure that the motor operates normally and the speed is stable at the preset minimum speed. During the treatment process, the controller 9 compares and analyzes the temperature data fed back by the temperature sensor 207 with the preset temperature threshold. When the temperature approaches or exceeds the upper limit threshold, the controller uses the PID algorithm to calculate the required wind speed increment, and accurately adjusts the input voltage or pulse width modulation (PWM) signal of the brushless DC motor through the drive circuit to gradually increase the speed of the wind drive device 9 to enhance the heat dissipation effect. When the temperature falls back to a safe range, the speed is gradually reduced to an appropriate level according to the corresponding algorithm, so as to achieve dynamic and precise adjustment of the wind speed, and effectively balance the relationship between heat dissipation requirements and equipment energy consumption and noise control.

[0073] Among them, after receiving the heat conducted from the heat conductive sheet 204, the heat dissipation component 203 dissipates the heat through the convection heat exchange between the heat sink and the air. At the same time, the cooling sheet 205 produces a cooling effect according to the temperature requirement of the treatment sheet 210 under the control of the controller 9. The cold surface of the cooling sheet 205 absorbs the heat from the treatment sheet, and the hot surface transfers the heat to the heat dissipation component 203. In this process, by optimizing the material, structure and ventilation conditions of the heat sink, and accurately controlling the cooling power and working time of the cooling sheet, a dynamic balance between heat dissipation and refrigeration is achieved to ensure that the temperature of the treatment sheet is stable within the set treatment temperature range. For example, when the temperature of the treatment sheet rises, the cooling sheet 205 increases the cooling power, and the heat dissipation component 203 speeds up the heat dissipation speed; when the temperature drops, the cooling and heat dissipation parameters are adjusted accordingly, so that the entire system is always in an efficient and stable thermal balance state.

[0074] When replacing the treatment head 2, the user first presses the elastic buttons on both sides of the connector to disengage the limit rod from the connector slot, and then gently pulls out the old treatment head 2. When installing a new treatment head 2, align the connection plate 201 of the treatment head 2 with the inclined surface of the connector 7, and insert it along the guide direction until you hear the crisp sound of the limit rod being inserted into the slot, ensuring that the treatment head is installed in place. During the replacement process, be sure to turn off the power of the beauty instrument to avoid electric shock or equipment damage due to misoperation. At the same time, before installing the new treatment head, ensure that its surface is clean and undamaged, and that the electrode point is in good contact with the power pin to ensure the normal operation and treatment effect of the equipment.

[0075] Among them, for example: in the skin tightening treatment mode, the controller 9 presets a higher treatment temperature range, such as 40°C-45°C. In the early stage of treatment, the wind drive device 6 runs at a lower speed, and the refrigeration plate 205 is in a low-power refrigeration state. As the treatment progresses, the temperature sensor 207 monitors the temperature of the treatment plate 210 in real time. When the temperature approaches or exceeds the upper limit threshold, the controller 9 gradually increases the speed of the wind drive device 6 and appropriately increases the refrigeration power of the refrigeration plate 205 to stabilize the temperature within the set range. For example: in the soothing and repairing treatment mode, the preset temperature range is relatively low, such as 35°C-40°C, and the initial working state and adjustment strategy of the wind drive device 9 and the refrigeration plate 205 are adjusted accordingly to meet the specific requirements of temperature control in different treatment modes and ensure the effectiveness and safety of the treatment effect.
