Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0047] The utility model proposes a skin care device, referring to Figure 1-Figure 3 , the skin care device 10 comprises:

[0048] The housing assembly 100 includes a first end portion 110 , a second end portion 120 , and a peripheral portion 130 connected between the first end portion 110 and the second end portion 120 . The first end portion 110 and the peripheral portion 130 enclose an inner cavity 140 .

[0049] The care component 200 is at least partially received in the inner cavity 140 and is used to care for the skin through the first end portion 110;

[0050] The heat dissipation device 300 includes a radiator 310 and a fan 320. The radiator 310 is arranged in the inner cavity 140 and is used to absorb at least part of the heat of the care component 200; the fan 320 is arranged in the inner cavity 140, and the fan 320 is stacked on one side of the radiator 310 in a direction perpendicular to the extension direction of the first end 110 toward the second end 120.

[0051] Skin care device 10 refers to a device that can improve and regulate human skin based on human physiological functions. Based on their cosmetic benefits, skin care devices 10 include, but are not limited to, hair removal devices, whitening devices, skin rejuvenation devices, wrinkle removal devices, and freckle removal devices. In some embodiments, a single skin care device 10 can have one or more cosmetic benefits. For example, a single skin care device 10 can simultaneously remove hair and achieve skin rejuvenation, or alternatively, remove hair, whiten skin, and achieve skin rejuvenation.

[0052] like Figure 2 As shown, in this embodiment, the housing assembly 100 of the skin care device 10 is primarily used for user gripping and provides a mounting location for other components. To facilitate gripping, the housing assembly 100 can be designed into an ergonomic shape, such as a streamlined shape or a handle with a non-slip design, to improve grip comfort and stability.

[0053] The material of the housing assembly 100 can be selected based on different needs. For example, to reduce the overall weight, a lightweight, high-strength material such as carbon fiber or aluminum alloy can be used. Considering the user's comfort when holding, the surface of the housing assembly 100 can be made of a soft-touch material such as silicone or polyurethane coating. These materials not only provide a soft touch, but also can increase the anti-slip effect through surface treatment processes (such as spraying, plating, or rubber coating), thereby improving the user experience of the device.

[0054] The care component 200 is used to care for the skin. Different types of care components 200 are set on the shell component 100 in different ways. For example, if the care component 200 cares for the skin by emitting light to irradiate the skin, the care component 200 can be completely set in the inner cavity 140 of the shell component 100; if the care component 200 stimulates the skin by contacting the skin with electrodes and releasing current, a part of the care component 200 is set outside the shell component 100 for care close to the skin, wherein the material of the electrode can be made of a material with excellent conductivity and safe for the skin, such as stainless steel, silver or gold-plated copper, which can not only effectively conduct current, but also have good corrosion resistance, ensuring the stability of the device during long-term use. The care component 200 can also include a light-transmitting component, a sensor, a cooling component 230, a control circuit, etc., auxiliary electrodes, light-emitting devices and other structures to complete the care of the skin to enhance the user experience.

[0055] The heat dissipation device 300 is used to dissipate the heat generated by the care component 200 during operation to the external environment to maintain the stability of the skin care device 10 and prevent the care component 200 from overheating and causing malfunction. The heat dissipation device 300 includes a radiator 310 and a fan 320, wherein the radiator 310 is arranged in the inner cavity 140 and is usually made of a material with high thermal conductivity such as metal, so that it can quickly absorb the heat of the care component 200 and keep the care component 200 working at a lower temperature; the fan 320 is usually made of heat-resistant materials, such as plastic, metal, etc., and conducts the heat from the radiator 310 and the care component 200 by driving the air flow. It can be understood that the air outlet or air inlet of the fan 320 can be directly set toward the radiator 310 so that the air flows through the radiator 310 under the drive of the fan 320, or the air outlet and air inlet of the fan 320 can be set in other directions, and the air is guided to the radiator 310 by a guiding structure (such as an air guide plate). The present invention does not impose any restrictions on this.

[0056] The fan 320 and the radiator 310 are stacked in the thickness direction of the skin care device 10, and there are various specific stacking methods. For example, if the air inlet of the fan 320 is arranged toward the radiator 310, the fan 320 and the radiator 310 can be staggered. In this case, the air inlet of the fan 320 is partially arranged above the radiator 310, and partially arranged above other components that are prone to heat (such as the circuit board 400, the power module, and the ultrasonic module). This improves the cooling effect of the fan 320 on these components, thereby ensuring the stability of the skin care device 10 during use. The fan 320 and the radiator 310 can also be coaxially arranged, that is, the fan 320 and the radiator 310 completely overlap or substantially overlap, so as to maximize the effect of the radiator 310.

[0057] In this embodiment, the heat sink 310 and the fan 320 are stacked together along a direction extending perpendicularly from the first end 110 toward the second end 120, so that the heat sink 300 occupies space in the thickness direction of the skin care device 10, reducing the overall length of the skin care device 10 and making it more compact and portable. Furthermore, the stacked arrangement allows the airflow generated by the fan 320 to pass directly through the heat sink 310, maximizing heat dissipation efficiency and ensuring that the device can quickly cool down during operation, thereby improving device performance and user experience. Furthermore, an overly long beauty device results in internal components being spaced far apart, which is not conducive to electrical connections between the components. The skin care device 10 of the present invention has a compact overall structure, and the length of the wires required to connect the various components is shorter, making the wire arrangement more convenient and further reducing the size of the skin care device 10.

[0058] like Figure 3As shown, in some embodiments, the fan 320 is stacked on one side of the heat sink 310 along the thickness direction of the skin care device 10 .

[0059] The thickness direction of the skin care device 10 is the direction perpendicular to the horizontal plane when the user uses the skin care device 10 in a standard holding posture, and the width direction and length direction of the skin care device 10 are perpendicular to the thickness direction, and the width of the skin care device 10 is smaller than the length. Figure 8 The thickness direction of the skin care device 10 is the ZZ' direction, the length direction is the XX' direction, and the width direction is the YY' direction. Stacking the fan 320 and the radiator 310 along the thickness direction of the skin care device 10 allows the fan 320 and the radiator 310 to be placed horizontally within the inner cavity 140 during use. This makes them less susceptible to the shaking of the skin care device 10 and improves the stability of the fan 320 and the radiator 310. Furthermore, stacking the fan 320 on one side of the radiator 310 along the thickness direction of the skin care device 10 utilizes the space within the thickness of the skin care device 10, allowing internal components to be arranged in both the thickness and length directions. This allows for more efficient use of the space within the skin care device and results in a more compact device configuration.

[0060] It is understandable that the skin care device 10 may have a variety of holding postures. In this case, one of the holding postures is selected as the standard holding posture, and the thickness direction of the skin care device 10 is determined accordingly.

[0061] like Figure 3 and Figure 4 As shown, in some embodiments, the skin care device 10 further includes a circuit board 400 , and the heat sink 310 is formed with a receiving groove 311 , and at least a portion of the circuit board 400 is received in the receiving groove 311 .

[0062] In order for the skin care device 10 to function properly and have different operating modes, a circuit board 400 is typically installed within the device to control the on / off state, power level, or mode switching of the skin care device 10. However, the circuit board 400 in existing skin care devices 10 is relatively large, resulting in the circuit board 400 occupying a significant amount of space within the device 10, hindering the installation of other components. This, in turn, makes the skin care device 10 excessively large and inconvenient to use.

[0063] Therefore, the present invention provides a receiving groove 311 on the heat sink 310 within the skin care device 10 and utilizes this receiving groove 311 to accommodate the circuit board 400, effectively reducing the space occupied by the circuit board 400 within the skin care device 10. The shape and location of the receiving groove 311 can be designed according to actual needs. For example, the receiving groove 311 can be a prism, cylinder, or other irregular shape, and can be located on the top or side of the heat sink 310, depending on the layout requirements of the circuit board 400 within the device. It is understood that the receiving groove 311 can be composed of multiple grooves, such as a "7"-shaped receiving groove 311 located on both the top and side of the heat sink 310 to accommodate circuit boards 400 of different shapes. Alternatively, multiple receiving grooves 311 located at different positions can be provided to accommodate circuit boards 400 in different positions.

[0064] During installation, first align the circuit board 400 with the receiving groove 311 to ensure that the circuit board 400 is in close contact with the heat sink 310. Then, place the circuit board 400 smoothly into the receiving groove 311 and securely attach the circuit board 400 to the heat sink 310 using screws, snaps, welding, or adhesive. After installation, the circuit board 400 and the heat sink 310 maintain good thermal contact, allowing the heat sink 310 to effectively absorb the heat generated by the circuit board 400 during operation. At the same time, some air driven by the fan 320 will flow through the circuit board 400, further reducing the temperature of the circuit board 400.

[0065] In this embodiment, at least a portion of the circuit board 400 is disposed in the receiving groove 311 of the radiator 310. On the one hand, this embedded installation method reduces the occupation of the internal space of the skin care device 10 by the circuit board 400, making the structure of the skin care device 10 more compact; on the other hand, the setting of the receiving groove 311 enables the circuit board 400 to be in close contact with the radiator 310, and the heat on the circuit board 400 can be quickly transferred to the radiator 310, maximizing the heat dissipation effect of the radiator 310, and helping to extend the service life of the circuit board 400, thereby improving the stability and reliability of the skin care device 10 during long-term use.

[0066] like Figure 1 、 Figure 3 and Figure 7 As shown, in some embodiments, the skin care device 10 further includes a control component 500, which is at least partially exposed outside the housing assembly 100 for user control;

[0067] The receiving groove 311 has a notch 311 a facing the control component 500 , and the circuit board 400 is electrically connected to the control component 500 via the notch 311 a .

[0068] The control device 500 may have multiple functions, such as turning the device power on and off, adjusting the nursing mode, setting the luminous intensity, adjusting the size of the electrode output current, etc.; and the control device 500 can use different methods to control the above functions, such as buttons, knobs, touch screens or sliders, and can be designed according to actual needs. It is understandable that to facilitate the user to control the control device 500, at least a portion of the control device 500, such as buttons or touch screens, is disposed on the outer surface of the housing assembly 100 to facilitate the user to complete pressing or touching operations. If the control device 500 includes a knob or slider, the user can switch modes or adjust parameters by rotating or sliding.

[0069] The accommodating groove 311 is provided with a notch 311a facing the control device 500. The circuit board 400 is electrically connected to the control device 500 through this notch 311a. Specifically, the circuit board 400 can be connected to the control device 500 via a flat cable, pins, or direct soldering to enable signal transmission between the control device 500 and the circuit board 400. The notch 311a of the accommodating groove 311 provides a connection path between the circuit board 400 and the control device 500. The notch 311a facing the control device 500 reduces the length and complexity of the connecting wires, making the connection between the circuit board 400 and the control device 500 more convenient and reducing the risk of signal transmission delays and interference.

[0070] Moreover, in this embodiment, the fan 320, the radiator 310, the circuit board 400 and the control device 500 are stacked together, which reduces the distance between the four components and simplifies the circuit connection between them, thereby greatly saving the space inside the skin care device 10, making the components more compact and the overall volume of the skin care device 10 smaller, which is convenient for users to carry and use.

[0071] Preferably, the shape of the slot 311a in this embodiment corresponds to the shape of the circuit board 400, so that the circuit board 400 can be installed or removed through the slot 311a, which helps to improve the maintainability of the equipment. When the control device 500 or the circuit board 400 needs to be replaced, the disassembly and assembly process will be simpler and faster, reducing maintenance costs and time.

[0072] like Figure 5 As shown, in some embodiments, the control device 500 includes at least one of the following components: a gear control component for adjusting the working gear of the skin care device 10, and a mode control component 520 for adjusting the working mode of the skin care device 10.

[0073] The gear control component is used to adjust the operating gear of the skin care device 10, such as adjusting the luminous intensity, heat output, microcurrent level, and radiofrequency current power. The user can use the gear control component to select the gear that suits their skin condition, ensuring the safety and effectiveness of the treatment process. Specifically, the gear control component can take the form of a knob, buttons with multiple different gears, a slider, or virtual buttons on a touch screen, thereby gradually adjusting the operating gear of the skin care device 10.

[0074] The mode control component 520 is used to switch between different operating modes of the skin care device 10, such as light therapy mode, thermal therapy mode, ultrasonic therapy mode, and microcurrent therapy mode. Different modes are used to meet different care needs, such as whitening, wrinkle removal, and skin firming. The user can select the appropriate mode as needed. The configuration of the mode control component 520 is similar to that of the gear control component and will not be repeated here.

[0075] By combining the gear control component and the mode control component 520, the user can more accurately control the operation of the skin care device 10. The gear control component allows the user to adjust the output power of the skin care device 10 according to the actual situation of the skin, while the mode control component 520 allows the user to quickly switch care functions, making the skin care device 10 more multifunctional, thereby improving the user experience and meeting the needs of different users.

[0076] like Figure 4 、 Figure 5 and Figure 7 As shown, in some embodiments, the circuit board 400 is arranged along the direction from the first end 110 to the second end 120, and the circuit board 400 includes a first section 410, a second section 420, and a third section 430 connected in sequence. The second section 420 is accommodated in the receiving groove 311, and the first section 410 and the third section 430 extend from both ends of the receiving groove 311 and protrude from the receiving groove 311 respectively.

[0077] The second section 420 is electrically connected to the control device 500;

[0078] The first section 410 and the third section 430 are respectively detachably connected to the inner sidewall of the peripheral side portion 130 .

[0079] In this embodiment, the circuit board 400 is arranged along the direction from the first end 110 to the second end 120 and is designed as a segmented structure. The shapes and sizes of the first segment 410, the second segment 420, and the third segment 430 can be selected according to design requirements. The first segment 410 and the third segment 430 extending from the second segment 420 can facilitate clamping the circuit board 400 during the installation process of the circuit board 400, so that the circuit board 400 can be installed more smoothly in the receiving groove 311, reducing the probability of bumping during installation. Preferably, the second segment 420 of the circuit board 400 is designed to be rectangular so that the circuit board 400 can be placed in the receiving groove 311 in a variety of ways. For example, the circuit board 400 can be placed flat in the receiving groove 311 of the heat sink 310, or the circuit board 400 can be inserted from one end of the receiving groove 311, further reducing the difficulty of installing the circuit board 400.

[0080] There are various ways to detachably connect the first section 410 and the third section 430 to the peripheral side portion 130. For example, hooks can be provided on the first section 410 and the third section 430, and corresponding snap rings can be provided on the inner side wall of the peripheral side portion 130 to achieve fixation through direct hooking of the hooks and snap rings. Alternatively, a dedicated slot can be provided on the inner side wall of the peripheral side portion 130 so that the first section 410 and the third section 430 of the circuit board 400 can be directly inserted into the slot for fixation. Alternatively, the connection can be made by magnetic attraction, which is not limited in the present invention. By detachably connecting the circuit board 400 and the inner side wall of the peripheral side portion 130, the stability of the installation of the circuit board 400 can be improved and the cleaning, disassembly, and replacement of the circuit board 400 can be facilitated.

[0081] like Figure 5 and Figure 6 As shown, in some embodiments, the first section 410 and the third section 430 are both constructed with an extension portion 440, and a mounting hole 441 is provided on the extension portion 440. A connecting hole 150 is provided at a position corresponding to the mounting hole 441 on the shell assembly 100, and the mounting hole 441 is screwed to the connecting hole 150.

[0082] The shape of the extension portion 440 can be configured based on the inner sidewall of the housing assembly 100. For example, if the inner sidewall of the housing assembly 100 is curved, the edge of the extension portion 440 can be configured to have a corresponding arc shape, so that the extension portion 440 fits more closely to the inner sidewall of the housing assembly 100, improving the stability of the circuit board 400 installation while avoiding excessive space occupation. The extension portion 440 can also be configured into other shapes, such as regular shapes that are easy to manufacture, such as rectangles or circles, or other irregular shapes.

[0083] During the installation process of the circuit board 400, first place the second section 420 of the circuit board 400 in the receiving groove, then adjust the position of the circuit board 400 so that the mounting hole 441 on the extension portion 440 is aligned with the connecting hole 150 on the shell assembly 100, and then insert the screws into the mounting hole 441 and the connecting hole 150, and gradually tighten them to ensure that the circuit board 400 is firmly fixed on the inner wall of the shell assembly 100.

[0084] In this embodiment, an extension portion 440 is provided and fixed to the inner wall of the shell assembly 100 with screws, so that the installation of the circuit board 400 is more secure. This not only effectively prevents the circuit board 400 from shifting due to vibration or bumping during the operation of the skin care device 10, thereby improving the stability of the circuit board 400, but also the diversified design of the extension portion 440 can be used to make the circuit board 400 adapt to different shell assemblies 100, providing a flexible fixing method.

[0085] like Figure 7 As shown, in some embodiments, the heat sink 310 includes a plurality of heat dissipation fins 312 disposed at intervals, and the receiving groove 311 includes a plurality of notches 312 a respectively formed on each heat dissipation fin 312 .

[0086] The heat sink 312 can be rectangular, corrugated, or needle-shaped. Rectangular heat sinks 312 have a simple structure, are easy to process and assemble, and are relatively inexpensive. Compared to rectangular heat sinks 312, corrugated heat sinks 312 have a larger surface area and better heat dissipation for the same volume, but are more difficult to install and weigh more. Needle-shaped heat sinks 312 can further increase the surface area of ​​the heat sink 312 and improve the heat dissipation efficiency of the radiator 310, but are more expensive, and needle-shaped heat sinks 312 can easily damage other components. In this embodiment, the heat sinks 312 are arranged in parallel to form the radiator 310. Air flows between the heat sinks 312 to transfer heat to the air, thereby reducing the temperature of the radiator 310.

[0087] The heat sink 312 is provided with notches 312a, which together constitute a receiving groove 311. The notches 312a on each heat sink 312 are aligned with each other. When multiple heat sinks 312 are arranged at intervals, these aligned notches 312a form a receiving groove 311, thereby accommodating the circuit board 400. The shape and size of the notches 312a can be set according to the size and shape of the circuit board 400 to ensure that the circuit board 400 can be smoothly inserted into the receiving groove 311 during installation. It is understandable that there can be multiple notches 312a on each heat sink 312, and the notches 312a on different heat sinks 312 do not need to be completely consistent. For example, if the circuit board 400 is curved, the positions of the notches 312a on different heat sinks 312 are different, and the design can be based on actual needs.

[0088] like Figure 3 and Figures 8-11 As shown, in some embodiments, the housing assembly 100 is provided with a first air inlet 160 and a first air outlet 170 , and the first air inlet 160 and the first air outlet 170 are respectively communicated with the inner cavity 140 ;

[0089] The fan 320 is used to drive air into the inner cavity 140 from the first air inlet 160 and to discharge air out of the inner cavity 140 through the first air outlet 170;

[0090] The fan 320 includes a second air inlet 321 and a second air outlet 322 . The second air inlet 321 is disposed toward the radiator 310 . The receiving groove 311 is disposed on a side of the radiator 310 facing away from the fan 320 .

[0091] Specifically, after the skin care device 10 is activated, air first flows into the inner cavity 140 from the first air inlet 160, driven by the fan 320, and then flows to the second air inlet 321 of the fan 320. The air is then blown out of the second air outlet 322 of the fan 320 and discharged out of the inner cavity 140 through the first air outlet 170. This air flow path creates a stable air circulation within the skin care device 10. The continuous air flow effectively prevents overheating of the components within the inner cavity 140, thereby improving the stability of the skin care device 10 during operation.

[0092] The second air inlet 321 of the fan 320 is positioned toward the radiator 310, so that when air flows toward the second air inlet 321, it passes through the radiator 310 and removes heat from the radiator 310, thereby effectively cooling the radiator 310 and, in turn, cooling the care component 200 connected to the radiator 310. The receiving groove 311 is positioned on the side of the radiator 310 facing away from the fan 320, so that the circuit board 400 is not affected by the fan 320 when installed in the receiving groove 311. At the same time, when the fan 320 is in operation, the air entering through the second air inlet 321 is not likely to flow through the circuit board 400, and dust and mist carried in the air will not significantly affect the circuit board 400, thereby extending the service life of the circuit board 400.

[0093] like Figure 9 and Figure 10 As shown, in some embodiments, the care device includes a light-emitting component 210, a light-transmitting skin-applying component 220, and a cooling component 230;

[0094] The first end portion 110 is provided with an opening communicating with the inner cavity 140, and the light-transmitting skin-adhesive member 220 is mounted in the opening;

[0095] The light emitting component 210 is disposed in the inner cavity 140 and irradiates light toward the light-transmitting skin-adhering component 220 to provide skin care through the light-transmitting skin-adhering component 220;

[0096] The cooling element 230 is installed in the inner cavity 140 to cool the light-transmitting skin-applying element 220;

[0097] The heat dissipation device 300 further includes an air guide 330 and a heat dissipation pipe. The air guide 330 is disposed in the inner cavity 140 and forms a heat dissipation duct in the housing assembly 100. The heat dissipation duct extends from the second air outlet 322 to the first air outlet 170. The light-emitting component 210 is disposed in the heat dissipation duct.

[0098] One end of the heat dissipation pipe is connected to the cooling element 230 , and the other end is connected to the radiator 310 .

[0099] The light-emitting component 210 is arranged in the outer inner cavity 140 and emits light toward the light-transmitting skin-adhesive component 220 to care for the skin through the light-transmitting skin-adhesive component 220. The light-emitting component 210 can adopt various types of light sources, such as LED lamps, halogen lamps or xenon lamps. These light sources can achieve different cosmetic effects according to different wavelengths and intensities. It can be understood that light of different wavelengths has different cosmetic effects. For example, blue light with a wavelength of 400-500nm is suitable for eliminating skin inflammation; red light with a wavelength of 600-700nm helps promote blood circulation and cell regeneration, and enhance skin elasticity; and near-infrared light (800-1000nm) can penetrate deep into the subcutaneous tissue, help reduce inflammation and accelerate skin repair.

[0100] The light-transmitting skin-adhesive member 220 is usually made of a crystal material, specifically sapphire, K9 glass, crystal glass, or other materials that meet the requirements of light-transmitting crystals. It can optionally be made of sapphire, and the shape and size of the light-transmitting skin-adhesive member 220 can be set according to actual needs. The light-transmitting skin-adhesive member 220 can be installed on the first end 110 of the skin care device 10 by mechanical fixation or bonding, wherein the mechanical fixation method includes the use of a buckle, screw, or embedded design to ensure that the light-transmitting skin-adhesive member 220 is firmly installed on the first end 110. During specific use, the light-emitting component 210 in the skin care device 10 is controlled to emit light toward the light-transmitting skin-adhesive member 220, so that the light is emitted from the light-transmitting skin-adhesive member 220 and irradiates the user's skin, thereby achieving skin care.

[0101] The cooling element 230 and the heat dissipation device 300 are generally made of materials with high heat dissipation efficiency, such as metal alloys. The cooling element 230 is connected to the radiator 310 via a heat pipe, so that the heat absorbed by the cooling element 230 from the light-transmitting skin-applying member 220 can be quickly transferred to the radiator 310 via the heat pipe, and the heat of the radiator 310 disposed between the second air inlet 321 and the third side of the fan 320 can be discharged from the inner cavity 140 through air flow, thereby enabling the cooling element 230 to continuously and effectively cool the light-transmitting skin-applying member 220. The cooling element 230 can be directly disposed on the light-transmitting skin-applying member 220 to absorb the heat of the light-transmitting skin-applying member 220, or it can indirectly absorb the heat of the light-transmitting skin-applying member 220 through other heat-conducting structures, and the present invention does not impose any restrictions on this.

[0102] The air guide 330 can be designed as a closed pipe structure, with one end of the pipe structure connected to the second air outlet 322 of the fan 320, and the other end connected to the first air outlet 170, so as to guide the air blown out by the fan 320 to flow continuously to the inner cavity 140, wherein the shape of the pipe structure can be set according to actual needs, and can be cylindrical, box-shaped or other irregular shapes; the air guide 330 can also be an open plate-like structure, guiding the airflow through specific angles and bending designs, and this embodiment does not impose any restrictions on this.

[0103] The setting of the air guide 330 allows the air to move along a clear and controlled flow path (i.e., the heat dissipation duct) within the inner cavity 140, and the light-emitting component 210 is set in the heat dissipation duct, so that air continuously flows through the light-emitting component 210, taking away the heat of the light-emitting component 210 and discharging it out of the equipment through the first air outlet 170, ensuring that the light-emitting component 210 can continue to maintain a low temperature during operation, avoiding excessive temperature affecting the normal use of the light-emitting component 210.

[0104] In this embodiment, the light-transmitting skin-adhesive component 220 is in direct contact with the skin when in use. After the heat on the skin is conducted to the light-transmitting skin-adhesive component 220, it is conducted to the radiator 310 through the refrigeration component 230 and the heat dissipation pipe, and is finally carried out of the inner cavity 140 by the flowing air, thereby maximizing the use of the heat conduction capacity of the air flow and the heat dissipation pipe, improving the overall heat dissipation efficiency of the device, enabling the device to operate stably for a longer period of time, and enabling the light-transmitting skin-adhesive component 220 to be maintained in a lower and stable temperature range, thereby reducing the burning sensation caused by light exposure to the skin, greatly improving the user experience.

[0105] The present invention also proposes a heat dissipation device 300, referring to 3 and Figure 7The heat dissipation device 300 includes a heat sink 310, which is disposed in the skin care device 10 and has a receiving groove 311 for receiving at least part of the circuit board 400. The configuration of the receiving groove 311 is similar to that in the above embodiment and will not be repeated here.
