[0070] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0071] Please refer to Figures 1 and 2. Figure 1 is a schematic structural diagram of a skin treatment device provided in an embodiment of the present application, and Figure 2 is a cross-sectional view of the skin treatment device shown in Figure 1 along the AA direction. An embodiment of the present application provides a skin treatment device.

[0072] Skin treatment devices are devices that adjust to human physiological functions to improve the condition of the skin on the body and face. They offer a range of functions, including whitening, rejuvenation, freckle removal, wrinkle reduction, and hair removal. Optical-based treatments employ specific wavelengths or different types of light to achieve diverse effects. Examples of these widely used devices include intense pulsed light (IPL), LED light, and lasers.

[0073] For example, the skin treatment device is a hair removal device or a skin rejuvenation device.

[0074] The skin treatment device may include a housing 100 , a light output component 200 , a cold compress component 300 , and a heat dissipation component 400 .

[0075] The housing 100 is provided with a light-emitting area 11. A light-emitting assembly 200 is disposed within the housing 100 and is used to generate light that is directed from the light-emitting area 11 toward the skin to be treated. A cold compress assembly 300 is disposed within the light-emitting area 11 for applying a cold compress to the skin. A heat dissipation assembly 400 is used to dissipate heat from the light-emitting assembly 200 and / or the cold compress assembly 300.

[0076] Skin treatment devices can be categorized into different types based on the type of light generated by the light emitting assembly 200. For example, the light emitting assembly 200 can be configured to generate laser light, in which case it is a laser light source assembly, and the skin treatment device is a laser-type skin treatment device. Another example is the light emitting assembly 200 can be configured to generate IPL light (intense pulsed light), in which case it is an IPL light source assembly (e.g., a xenon lamp assembly), and the skin treatment device is an intense pulsed light-type skin treatment device. Another example is the light emitting assembly 200 being an LED light source assembly.

[0077] This application will be described below primarily using an IPL light source as an example, using light-emitting assembly 200. The principle of light emission in this type of skin treatment device is as follows: a capacitor is connected to a power source, and a transformer boosts the voltage to charge the capacitor. When the capacitor reaches a preset value and the controller receives a trigger signal, the energy in the capacitor is released, resulting in a transient voltage of several hundred volts. This in turn stimulates the lamp to instantly release intense pulsed light, completing a single light emission cycle.

[0078] In some embodiments, the light exit area 11 may be an opening structure such as a light exit port or a light exit hole provided on the housing 100 .

[0079] Alternatively, the light emitting area 11 may be formed by some light-transmitting areas on the housing 100. For example, at least a portion of the housing 100 of the skin treatment device, such as the head shell, may be made of a light-transmitting material, with a light-shielding layer provided in a local area of ​​the head shell, thereby forming the light emitting area 11 in areas where the light-shielding layer is not provided. This embodiment of the present application is not limited to this.

[0080] The heat dissipation assembly 400 includes a fan 41 . The fan 41 is provided with a first air outlet 413 . The first air outlet 413 is provided on a side of the light emitting assembly 200 away from the light emitting area 11 .

[0081] A diversion structure 42a can also be provided in the shell 100, and the diversion structure 42a is arranged at the first air outlet 413, so that the fan 41 can drive the first part of the air flow through one side of the diversion structure 42a and dissipate heat to the light-emitting component 200, and the fan 41 can drive the second part of the air flow through the other side of the diversion structure 42a and dissipate heat to the cold compress component 300.

[0082] For example, in the embodiment of the present application, the first air outlet 413 can be an air outlet, so that the air blown out by the fan 41 can be divided into a first portion of air and a second portion of air through the diversion structure 42a, thereby respectively dissipating heat to the light output assembly 200 and the cold compress assembly 300. This allows both the light output assembly 200 and the cold compress assembly 300 to be effectively cooled, thereby improving the overall heat dissipation effect of the skin treatment device. Of course, the first air outlet 413 can also be the air inlet of the fan 41, and the embodiment of the present application is not limited to this.

[0083] The fan 41 can be a centrifugal fan, a cross-flow fan, etc., and this embodiment of the present application does not limit this.

[0084] For example, when the fan 41 is a centrifugal fan, the first air outlet 413 can be the air outlet or air inlet of the volute, the first air outlet 413 can also be the air outlet of the volute or the air outlet of the air duct component installed at the air inlet, etc., and the embodiments of the present application do not limit this.

[0085] When the fan 41 is a centrifugal fan, the width direction of the first air port 413 may also be the thickness direction of the volute.

[0086] In some embodiments, the fan 41 is further provided with a third air outlet 414. One of the first air outlet 413 and the third air outlet 414 serves as the air inlet of the fan 41, and the other of the first air outlet 413 and the third air outlet 414 serves as the air outlet of the fan 41. Accordingly, the housing 100 is further provided with a fourth air outlet 12, which is in communication with the exterior of the housing 100 and the third air outlet 414, respectively.

[0087] When the first air outlet 413 is the air outlet, the fan 41 first sucks the air outside the shell 100 through the third air outlet 414 and the fourth air outlet 12, and then the fan 41 flows the sucked air out from the first air outlet 413 and is diverted by the diversion structure 42a, thereby realizing heat dissipation of the cold compress component 300 and the light output component 200.

[0088] For example, the fourth air outlet 12 may include a first shell air inlet 121 , and the first shell air inlet 121 is arranged to correspond to (eg, directly opposite to) the air inlet of the fan 41 .

[0089] The fourth air outlet 12 may further include a second housing air inlet 122 . The second housing air inlet 122 is disposed at an end of the housing 100 away from the light exit area 11 .

[0090] The above is an overall example of the technical solution of the embodiment of the present application. The following first illustrates the technical solution of the embodiment of the present application with reference to the optional structure of the diversion structure 42a.

[0091] It is understandable that the diversion structure 42a can be a part of the heat dissipation component 400, or a part of other components of the skin treatment device, and the embodiment of the present application does not limit this.

[0092] For example, please continue to refer to Figures 3 and 4. Figure 3 is a schematic diagram of the installation positions of the light output component, cold compress component, and heat dissipation component of the skin treatment device shown in Figure 2, and Figure 4 is a partial enlarged view of the X in Figure 2. The heat dissipation component 400 may also include a temperature averaging plate 42 and a heat sink 43 mounted on the temperature averaging plate 42. One end of the temperature averaging plate 42 is thermally connected to the cold compress component 300; for example, one end of the temperature averaging plate 42 is directly attached to the cold compress component 300 or attached to the cold compress component 300 through a heat conductive medium such as thermal grease, so that the heat at the cold compress component 300 can be evenly transferred to various positions of the temperature averaging plate 42, and then the contact area with the air is increased through the heat sink 43 to improve the heat dissipation efficiency of the cold compress component 300. The other end of the temperature averaging plate 42 is located at the first air outlet 413 to form at least part of the diversion structure 42a. Alternatively, it can also be understood that: the other end of the temperature equalizing plate 42 is located at the first air outlet 413, so that the fan 41 is used to drive the first part of the air flow through the temperature equalizing plate 42 away from the side of the heat sink 43 and the light output component 200, thereby dissipating the heat of the light output component 200, and the fan 41 is used to drive the second part of the air flow through the heat sink 43, thereby dissipating the heat of the cold compress component 300.

[0093] Since the fan 41 drives the first part of the wind and the second part of the wind to flow through different sides of the temperature equalizing plate 42 respectively, the contact area between the temperature equalizing plate 42 and the cooling airflow is increased, thereby improving the heat dissipation efficiency of the temperature equalizing plate 42, and then improving the heat dissipation effect of the cold compress component 300, and ultimately improving the overall heat dissipation effect of the skin treatment device.

[0094] It can also be understood that the temperature equalizing plate 42 forms at least part of the diversion structure 42a, which means that the diversion structure 42a can be formed only by the temperature equalizing plate 42, or it can be composed of the temperature equalizing plate 42 and its components. This embodiment of the application does not limit this.

[0095] Next, an overall description of the structure of the cold compress assembly 300 is given to explain the principle of heat dissipation of the cold compress assembly 300 by the temperature homogenizing plate 42 .

[0096] In some embodiments, the cold compress assembly 300 is disposed at the light exiting area 11 , and the cold compress assembly 300 can pass through the light exiting area 11 , or the cold compress assembly 300 can be disposed at the end face of the hole of the light exiting area 11 .

[0097] For example, the cold compress assembly 300 may include a first light guide component 31 and a cooling plate 32. The first light guide component 31 is disposed in the light emitting region 11 to transmit light emitted by the light emitting assembly 200. The cooling plate 32 is thermally connected to the first light guide component 31. For example, the cooling plate 32 may be directly attached to the first light guide component 31 or attached to the first light guide component 31 via a heat-conducting medium such as thermal grease.

[0098] Furthermore, the first light guide component 31 can be cooled by the cooling sheet 32. The cooled first light guide component 31 is exposed from the light exit area 11 so that it can come into contact with the skin, so that the first light guide component 31 can not only transmit the light of the light source 22 to care for the user's skin, but also be cooled by the cooling sheet 32 ​​to provide a cold compress for the user.

[0099] Specifically, the cooling plate 32 is also called a semiconductor cooling plate. It uses the Peltier effect of semiconductor materials. When direct current passes through a galvanic couple composed of two different semiconductor materials connected in series, heat can be absorbed and released at both ends of the galvanic couple respectively, thereby achieving the purpose of cooling.

[0100] The first light-guiding component 31 may be made of sapphire or other light-guiding materials, which is not limited in this embodiment of the present application.

[0101] Optionally, the cold compress assembly 300 may further include a cold compress (not shown in the figure) and a cooling sheet 32. The cold compress is arranged on one side / around the light emitting area 11. The cooling sheet 32 ​​is thermally connected to the cold compress. For example, the cooling sheet 32 ​​is directly attached to the cold compress or is attached to the cold compress through a heat-conducting medium such as thermal grease. Furthermore, the cold compress can be cooled by the cooling sheet 32, and the cooled cold compress is exposed from one side / around the light emitting area 11 so that it can come into contact with the skin to provide a cold compress to the user.

[0102] For example, the cold compress may be a ring-shaped metal part arranged around the light emitting area 11 .

[0103] The thermal connection between the temperature averaging plate 42 and the cold compress assembly 300 can be a thermal connection between the temperature averaging plate 42 and the cooling fin 32. For example, the temperature averaging plate 42 can be directly attached to the cooling fin 32 or attached to the cooling fin 32 via a thermally conductive medium such as thermal grease. This allows heat from the cooling fin 32 to be evenly and quickly transferred to all parts of the temperature averaging plate 42. The temperature averaging plate 42 then increases its contact area with the air through the heat sink 43, thereby achieving rapid heat dissipation.

[0104] Continuing with the example of the temperature equalizing plate 42 forming at least a portion of the diversion structure 42a, the skin treatment device may further include a bracket assembly 500. The bracket assembly 500 is disposed inside the housing 100. The bracket assembly 500 and the temperature equalizing plate 42 form a first heat dissipation duct 51 and a second heat dissipation duct 52. The light output component 200 is at least partially installed in the first heat dissipation duct 51, so that a first portion of the wind flows into the first heat dissipation duct 51 to dissipate heat for the light output component 200. The heat sink 43 is disposed in the second heat dissipation duct 52, so that a second portion of the wind flows into the second heat dissipation duct 52 to dissipate heat for the cold compress component 300. Furthermore, by dissipating heat for the light output component 200 and the cold compress component 300 respectively, the heat dissipation effects of both the light output component 200 and the cold compress component 300 can be guaranteed.

[0105] For example, one side of the temperature vapor chamber 42, such as the side facing away from the heat sink 43, forms a near-air outlet section of the first heat dissipation duct 51 with the bracket assembly 500. The near-air outlet section of the first heat dissipation duct 51 is connected to the first air outlet 413, so that the fan 41 is used to / can drive a first portion of air to flow through the first heat dissipation duct 51, thereby dissipating heat from the light output assembly 200. The other side of the temperature vapor chamber 42, such as the side close to the heat sink 43, forms a near-air outlet section of the second heat dissipation duct 52 with the bracket assembly 500. The near-air outlet section of the second heat dissipation duct 52 is connected to the first air outlet 413, so that the fan 41 can drive a second portion of air to flow through the second heat dissipation duct 52, thereby dissipating heat from the cold compress assembly 300. Furthermore, the near-air-outlet section of the first heat dissipation duct 51 and the near-air-outlet section of the second heat dissipation duct 52 are respectively formed on both sides of the temperature equilibrium plate, so that the first part of the wind can dissipate heat to the light-emitting component 200 while also dissipating heat to the temperature equilibrium plate 42, so as to be reused for dissipating heat to the cold compress component 300.

[0106] In some embodiments, the bracket assembly 500 may be provided with corresponding slots and ribs therein for mounting the light output assembly 200 , the cold compress assembly 300 and at least part of the heat dissipation assembly 400 .

[0107] In some embodiments, the inner wall of the first heat dissipation duct 51 may be provided with a light exit portion 53. The light exit portion 53 is located between the light exit assembly 200 and the light exit area 11 of the housing 100. The light exit portion 53 is used to transmit the light generated by the light exit assembly 200 to the light exit area 11.

[0108] For example, the light exit portion 53 may be a through hole, and the cold compress assembly 300 , such as the first light guide component 31 of the cold compress assembly 300 , is disposed through the light exit portion 53 , thereby closing the light exit portion 53 .

[0109] Alternatively, the light exit portion 53 may be a second light guide component provided on a side of the inner wall of the first heat dissipation duct 51 facing the light exit area 11 .

[0110] The second light guide component can be a heat-insulating light-transmitting component to prevent the heat generated by the light output component 200 from being directly transferred to the cold compress component 300. Of course, the second light guide component may not be a heat-insulating light-transmitting component, and this embodiment of the application does not limit this.

[0111] Alternatively, the second light guiding component is a filter.

[0112] The bracket assembly 500 may also include a filter component 54. The filter component 54 may include a filter. The filter component 54 is used to transmit light with a wavelength between 560 nanometers and 1200 nanometers, thereby forming IPL (intense pulsed light) light within a specific wavelength range to irradiate the user's skin. In actual use, the wavelength of light required for hair removal may be between 560 nanometers and 1200 nanometers, and the wavelength of light required for skin rejuvenation may be between 640 nanometers and 1200 nanometers. This allows the skin care device to have both cold compress and skin rejuvenation or hair removal functions. Of course, other functions can also be achieved by setting the light output component 200, or the light output component 200 and the filter.

[0113] In some embodiments, by adjusting the type of the filter, the second light guide component, the filter component 54, and the first light guide component 31 can be arranged sequentially in a direction away from the light output assembly 200. This allows the skin care device to simultaneously have the functions of cold compress, skin rejuvenation, and hair removal.

[0114] In some embodiments, the skin treatment device further includes a support assembly 500. The support assembly 500 is disposed within the housing 100 and, together with the vapor chamber 42, forms a first heat dissipation duct 51 for a first portion of airflow. The light output assembly 200 is at least partially disposed within the first heat dissipation duct 51, allowing the first portion of airflow to pass through the light output assembly 200, thereby dissipating heat from the light output assembly 200. The support assembly 500 may further include a partition 55, which separates the light output assembly 200 from the vapor chamber 42.

[0115] It is understood that the temperature averaging plate 42 may include a copper alloy temperature averaging plate, a VC (Vapor Chamber, vacuum chamber heat averaging plate heat dissipation technology) temperature averaging plate, a stainless steel temperature averaging plate, a graphene heat dissipation plate, etc., and this embodiment of the present application is not limited to this. The temperature averaging plate 42 is generally conductive. The isolation portion 55 can not only make the temperature averaging plate 42 and the light output component 200 closer, thereby making the skin treatment device as a whole lighter and thinner, but also avoid leakage caused by the light output component 200 and the temperature averaging plate 42 being too close, thereby improving the reliability and safety of the skin treatment device.

[0116] The isolation portion 55 may be made of an insulating material, such as plastic, rubber, ceramic, or even an insulating layer, and this embodiment of the present application does not limit this.

[0117] In some embodiments, along the direction from the light output assembly 200 toward the first air outlet 413, the isolation portion 55 is shorter than the heat evaporating plate 42 and is supported by the heat evaporating plate 42. Furthermore, the shorter isolation portion 55 can, on the one hand, reduce the difficulty and cost of manufacturing the bracket assembly 500, and lower the overall weight of the skin treatment device; on the other hand, it can also expose more of the heat evaporating plate 42, thereby increasing the area of ​​contact between the heat evaporating plate 42 and the first portion of air, thereby improving the heat dissipation efficiency of the heat evaporating plate 42 and ultimately improving the heat dissipation effect of the cold compress assembly 300.

[0118] In some embodiments, the surface of the vapor chamber 42 facing the light output assembly 200 includes a shielded area 422 and an exposed area 423. The isolation portion 55 is supported on the shielded area 422. The minimum distance between the exposed area 423 and the light output assembly 200 is greater than or equal to 6 mm, thereby preventing leakage caused by the vapor chamber 42 and the light output assembly 200 being too close.

[0119] For example, the minimum distance between the exposed area 423 and the light output component 200 may be 6 mm, 6.1 mm, 6.7 mm, 7.4 mm, 8 mm or 9 mm, etc., which is not limited in the embodiment of the present application.

[0120] In some embodiments, the surface of the vapor chamber 42 facing the light output assembly 200 includes a shielded area 422 and an exposed area 423. The isolation portion 55 is supported on the shielded area 422. The exposed area 423 is a flat area for guiding airflow and dissipating heat. It is understood that since the exposed area 423 also forms the inner wall of the first heat dissipation duct 51, the flat exposed area 423, compared to the uneven exposed area 423, can effectively reduce the wind resistance of the first portion of air flowing within the first heat dissipation duct 51.

[0121] Specifically, the minimum distance between the exposed area 423 and the light emitting component 200 may be greater than or equal to 6 mm, and the exposed area 423 may be a flat area; the minimum distance between the exposed area 423 and the light emitting component 200 may be less than 6 mm, and the exposed area 423 may be a flat area; or the minimum distance between the exposed area 423 and the light emitting component 200 may be less than 6 mm, and the surface of the exposed area 423 may be provided with a concave-convex structure. The embodiments of the present application do not limit this.

[0122] Next, the diversion structure 42a is taken as an example in which at least a part of it is formed by some other parts of the skin treatment device, and further explained.

[0123] For example, please continue to refer to Figure 5, which is a schematic diagram of another diversion structure at X in Figure 2. The skin treatment device also includes a bracket assembly 500. The bracket assembly 500 is disposed within the housing 100. The bracket assembly 500 is used to form a first heat dissipation duct 51 and a second heat dissipation duct 52. The first heat dissipation duct 51 is used to allow a first portion of air to flow to dissipate heat from the light output assembly 200, and the second heat dissipation duct 52 is used to allow a second portion of air to flow to dissipate heat from the cold compress assembly 300. A diversion portion 56 is provided at one end of the bracket assembly 500 near the first air outlet 413 to form a diversion structure 42a, thereby separating the air outlet of the first heat dissipation duct 51 from the air outlet of the fan 41 and the air outlet of the second heat dissipation duct 52 from the air outlet of the fan 41. Ultimately, by dissipating heat from the light output assembly 200 and the cold compress assembly 300 respectively, the heat dissipation effects of both the light output assembly 200 and the cold compress assembly 300 can be guaranteed.

[0124] Exemplarily, the light emitting assembly 200 is at least partially disposed in the first heat dissipation duct 51. Thus, after the first portion of wind flows into the first heat dissipation duct 51, the light emitting assembly 200 can be cooled.

[0125] The heat dissipation assembly 400 may further include a temperature evaporating plate 42 and a heat sink 43 mounted on the temperature evaporating plate 42. One end of the temperature evaporating plate 42 is thermally connected to the cold compress assembly 300. Both the temperature evaporating plate 42 and the heat sink 43 are at least partially disposed within the second heat dissipation duct 52. Thus, the second portion of air flowing into the second heat dissipation duct 52 dissipates heat from the temperature evaporating plate 42 and the heat sink 43, ultimately dissipating heat from the cold compress assembly 300.

[0126] In some embodiments, the light output assembly 200 is arranged to extend along the length of the first air outlet 413. For example, if the first air outlet 413 is the air outlet of the fan 41, the first portion of the air flowing out of the first air outlet 413 can be directly blown to more parts along the length of the light output assembly 200, thereby improving the heat dissipation effect and making the internal structure of the skin treatment device simpler and more compact.

[0127] In some embodiments, the first portion of air and the second portion of air can flow out from different regions along the width of the first air outlet 413. In other words, the near-air outlet section of the first heat dissipating air duct 51 (if the first air outlet 413 is an air outlet, the near-air outlet section of the first heat dissipating air duct 51 is its inlet section) and the near-air outlet section of the second heat dissipating air duct 52 (if the first air outlet 413 is an air outlet, the near-air outlet section of the second heat dissipating air duct 52 is its inlet section) are respectively connected to different regions along the width of the first air outlet 413.

[0128] For example, the length of the light output assembly 200 may extend in the left-right direction, and the length of the first air outlet 413 may also extend in the left-right direction. The inlet of the first heat dissipation duct 51 is connected to the lower half of the first air outlet 413, and the inlet of the second heat dissipation duct 52 is connected to the upper half of the first air outlet 413.

[0129] Please continue to refer to Figure 6, which is another cross-sectional view of the skin treatment device described in Figure 1 along the AA direction. The first heat dissipation duct 51 includes a mounting section 511 and a guide section 512 distributed along the direction of the light output component 200 toward the first air outlet 413. The light output component 200 is at least partially mounted on the mounting section 511. One end of the guide section 512 is located at the first air outlet 413 to communicate with the first air outlet 413, and the other end is connected to the mounting section 511. In this way, the first heat dissipation duct 51 and the fan 41 are connected. For example, the first part of the air flowing out of the first air outlet 413 can flow directly to the mounting section 511 via the guide section 512 to dissipate heat from the light output component 200.

[0130] It can be understood that the air outlet section of the first heat dissipation duct 51 is formed in the guide section 512 .

[0131] It should be noted that the light emitting assembly 200 being at least partially installed in the mounting section 511 can mean that the light emitting assembly 200 is completely disposed within the mounting section 511. The light emitting assembly 200 being at least partially installed in the mounting section 511 can also mean that the light emitting assembly 200 is only partially disposed within the mounting section 511. For example, the two ends of the light emitting assembly 200 are disposed through the inner wall of the mounting section 511, so that the light emitting assembly 200 is partially disposed outside the mounting section 511; or, the light emitting assembly 200 partially protrudes into the guide section 512, which is not limited in this embodiment of the present application.

[0132] In some embodiments, the cross-sectional area of ​​at least a portion of the air guiding section 512 gradually increases along a direction from the first air outlet 413 toward the light output assembly 200 .

[0133] Then, the guide section 512 can form a pressure diffusion structure. When part of the wind from the first air outlet 413 flows into the guide section 512, since the cross-sectional area of ​​the portion within the guide section 512 gradually increases along the wind flow direction, compared to when the cross-sectional area within the guide section 512 remains unchanged or gradually decreases along the wind flow direction, the wind resistance of the gas flowing within the guide section 512 will be smaller, thereby allowing more wind flowing out of the first air outlet 413 to flow smoothly into the guide section 512, thereby improving the heat dissipation effect on the light output component 200.

[0134] In some embodiments, the width of the guide section 512 gradually increases in the width direction of the first air outlet 413. This, on the one hand, facilitates the gradual increase in the cross-sectional area of ​​the guide section 512 along the air flow direction, and on the other hand, increases the contact area between the first portion of air and the light output assembly 200. This can further improve the heat dissipation effect of the first portion of air on the light output assembly 200.

[0135] In some embodiments, the inner wall of the flow guide section 512 includes a first inner wall 513 facing the diverter structure 42a and a second inner wall 514 opposite the first inner wall 513. Along the direction from the first air outlet 413 to the light output assembly 200, at least one of the first inner wall 513 and the second inner wall 514 is inclined away from the other, so that the distance between the first inner wall 513 and the second inner wall 514 gradually increases.

[0136] Specifically, the first inner wall 513 and the second inner wall 514 may both be tilted away from each other, or one of the first inner wall 513 and the second inner wall 514 may be tilted away from the other. This embodiment of the present application does not limit this.

[0137] It can also be understood that the second inner wall 514 can be formed by the above-mentioned diversion structure 42a such as the temperature equilibrium plate 42 and / or the diversion portion 56 of the bracket assembly 500, and the second inner wall 514 can also be formed by the diversion structure 42a and other components, which is not limited in this embodiment of the present application.

[0138] In some embodiments, in the direction from the first inner sidewall 513 to the second inner sidewall 514, the width of the guide section 512 at the end close to the light output assembly 200 is greater than or equal to the width of the light output assembly 200. Thus, the surface of the light output assembly 200 facing the first air outlet 413 can be directly blown by the first portion of wind flowing out of the fan 41, thereby increasing the heat dissipation area and thus improving the heat dissipation effect on the light output assembly 200.

[0139] Referring to Figures 6 and 7, Figure 7 is a partial enlarged view of point Y in Figure 6. A first anti-turbulence structure 515 is provided within the guide section 512 to limit the formation of turbulent flow within the guide section 512. This allows the first portion of wind to flow more smoothly from the guide section 512 into the mounting section 511 for heat dissipation, or in other words, allows the first portion of wind to flow faster within the guide section 512, thereby improving heat dissipation.

[0140] Illustratively, the light emitting assembly 200 includes a reflective component 21 and a light source 22 disposed in the reflective component 21 .

[0141] The outer wall of the reflective component 21 includes a first curved surface that is convex toward the flow guiding section 512. The first anti-turbulence structure 515 is used to limit the turbulence formed between the first curved surface and the inner wall of the flow guiding section 512.

[0142] Specifically, after the first portion of wind blows toward the light output assembly 200, it will be blocked by the first curved surface and partially return to the guide section 512. At this time, the first anti-turbulence structure 515 can prevent the airflow blocked by the first curved surface and returned to the guide section 512 from forming turbulence with the airflow flowing into the guide section 512 from the fan 41, thereby allowing the first portion of wind to flow more smoothly in the first heat dissipation duct 51, thereby improving the flow rate of the first portion of wind and the heat dissipation effect.

[0143] In one embodiment, the light source 22 may include a lamp tube. The reflective component 21 includes an arcuate portion 211 surrounding the lamp tube. The arcuate portion 211 is at least partially located on a side of the lamp tube adjacent to the flow guide section 512. One circumferential end of the arcuate portion 211 is adjacent to the first inner sidewall 513, and the other circumferential end of the arcuate portion 211 is adjacent to the second inner sidewall 514. A first anti-turbulence structure 515 is provided on the first inner sidewall 513 and / or the second inner sidewall 514.

[0144] Thus, the first anti-turbulence structure 515 can limit the wind returning from the outer surface of the arc-shaped portion 211 to the first inner sidewall 513 and / or the second inner sidewall 514 from forming turbulence.

[0145] Specifically, only the first inner wall 513 may be provided with the first anti-perturbation flow structure 515, or only the second inner wall 514 may be provided with the first anti-perturbation flow structure 515, or both the first inner wall 513 and the second inner wall 514 may be provided with the first anti-perturbation flow structure 515. This embodiment of the present application does not limit this.

[0146] In some embodiments, the first anti-spoiler structure 515 can be integrally formed with the corresponding first inner sidewall 513 or second inner sidewall 514. Of course, the first anti-spoiler structure 515 can also be separately formed with the corresponding first inner sidewall 513 or second inner sidewall 514. For example, the first anti-spoiler structure 515 can be detachably connected to the first inner sidewall 513 or second inner sidewall 514. This embodiment of the present application is not limited to this.

[0147] In some embodiments, the first anti-turbulence structure 515 includes a deflector. The deflector is provided along the first air outlet 413 in a direction toward the light output assembly 200, so that the first inner sidewall 513 and / or the second inner sidewall 514 provided with the deflector can guide the wind passing through the deflector to limit the formation of turbulence at the first inner sidewall 513 and / or the second inner sidewall 514.

[0148] The number of the guide plates can be one or more. For example, the first anti-turbulence structure 515 can include multiple guide plates, which are arranged at intervals along the length direction of the light output assembly 200, such as the length direction of the lamp tube.

[0149] In some embodiments, the first anti-turbulence structure 515 includes a deflector. The deflector includes a first inclined surface 5151 and a second inclined surface 5152 arranged opposite to each other along the thickness direction. Along the direction from the first air outlet 413 to the light output component 200, the first inclined surface 5151 and the second inclined surface 5152 are inclined in directions away from each other, so that the thickness of the deflector close to the light output component 200 is greater than the thickness of the deflector away from the light output component 200. Then, it can also be simply understood that the side of the deflector facing the first air outlet 413 is sharper, thereby forming a wind-breaking structure to reduce the wind resistance formed when the first part of the wind blows through the deflector, thereby improving the heat dissipation effect.

[0150] In some embodiments, the inner wall of the guide section 512 includes a first guide surface connected to the guide plate. The guide plate also includes a third inclined surface 5153. The third inclined surface 5153 is located on the side of the guide plate away from the first guide surface. Among them, along the direction of the first air outlet 413 toward the light output component 200, the third inclined surface 5153 is tilted in the direction away from the first guide surface, so that the height of the guide plate protruding from the first guide surface close to the light output component 200 is greater than the height of the guide plate protruding from the first guide surface away from the light output component 200. Then, it can also be simply understood that the side of the guide plate facing the first air outlet 413 is sharper, thereby forming a wind-breaking structure to reduce the wind resistance formed when the first part of the wind blows through the guide plate, thereby improving the heat dissipation effect.

[0151] In some embodiments, the heat dissipation assembly 400 further includes a temperature equalizing plate 42 and a heat sink 43 mounted on the temperature equalizing plate 42. One end of the temperature equalizing plate 42 is thermally connected to the cold compress assembly 300. The temperature equalizing plate 42 and the heat sink 43 are at least partially disposed in the second heat dissipation duct 52. Among them, the end of the temperature equalizing plate 42 close to the first air outlet 413 is bent toward the side close to the light output assembly 200 to form a deflection section 421. The deflection section 421 extends to the first air outlet 413, so that the side of the deflection section 421 close to the light output assembly 200 forms at least a portion of the guide section 512 with the bracket assembly 500, and the side of the deflection section 421 facing away from the light output assembly 200 forms the inlet section of the second heat dissipation duct 52 with the bracket assembly 500. In other words, the deflection section 421 extends to the first air outlet 413, so that the side of the deflection section 421 close to the light emitting component 200 and the bracket component 500 form at least a partial guide section 512, and the side of the deflection section 421 away from the light emitting component 200 and the bracket component 500 form the near-air outlet section of the second heat dissipation duct 52.

[0152] For example, the light output assembly 200 can be located below the vapor chamber 42. In this case, the lower surface of the vapor chamber 42 forms the upper sidewall of the inner wall of the first heat dissipation duct 51. Furthermore, the end of the vapor chamber 42 near the first air outlet 413 is bent downward, so that the bent section 421 of the vapor chamber 42 forms at least a portion of the second inner sidewall 514 of the air guide section 512. This simplifies the structure of the bracket assembly 500 and reduces the difficulty of molding the bracket assembly 500.

[0153] Please continue to refer to Figure 8, which is another schematic diagram of a partial enlarged view of the X in Figure 2. In some embodiments, the heat sink 43 may include a proximal heat sink section 431 and a distal heat sink section 432. The proximal heat sink section 431 is mounted on the deflection section 421. The distal heat sink section 432 is connected to the end of the proximal heat sink section 431 that is close to the light exit area 11. The width of the proximal heat sink section 431 is greater than the width of the distal heat sink section 432. The width of the heat sink 43 is the distance from the side of the heat sink 433 close to the vapor chamber 42 to the side of the heat sink 433 that is far from the vapor chamber 42.

[0154] The heat sink 43 includes a connecting side 433 mounted on the temperature homogenizing plate 42 and a free side 434 facing away from the temperature homogenizing plate 42 . The width of the heat sink 43 is the distance from the connecting side 433 to the free side 434 .

[0155] Then, considering that the deflection section 421 is deflected downward, the space formed by the downward deflection of the deflection section 421 can be reasonably utilized to make the heat dissipation section 431 larger, thereby increasing the contact area between the heat sink 43 and the air to improve the heat dissipation effect, while also ensuring that the overall structure of the skin treatment device is more compact and smaller in size.

[0156] For example, the heat sink 43 includes a connecting side 433 mounted on the temperature vapor chamber 42 and a free side 434 facing away from the temperature vapor chamber 42. In the direction from the light output assembly 200 toward the first air outlet 413, the connecting side 433 and the free side 434 of the heat dissipation section 431 near the heat dissipation section are tilted away from each other, so that the width of the heat dissipation section 431 near the heat dissipation section 431 gradually increases.

[0157] In some embodiments, the housing 100 includes a light emitting section extending from the connection between the near heat dissipation section 431 and the far heat dissipation section 432 to the light emitting area 11. In this case, the cross-sectional area of ​​the light emitting section gradually decreases along the direction of the light emitting assembly 200 toward the light emitting area 11. This makes the end face of the housing on the side of the light emitting area 11 smaller, so that the user can accurately fit the light emitting area 11 to the user's skin to be treated. Accordingly, the height of the far heat dissipation section 432 protruding from the temperature equalizing plate 42 is also smaller, and the height of the near heat dissipation section 431 protruding from the temperature equalizing plate 42 is also correspondingly greater than the height of the far heat dissipation section 432 protruding from the temperature equalizing plate 42.

[0158] In some embodiments, there are multiple heat sinks 43. Each heat sink 43 includes a connecting side 433 mounted to the vapor chamber 42 and a free side 434 facing away from the vapor chamber 42. The free sides 434 of the multiple heat sinks 43 form a free side surface, which includes a windshield area 435 near the first air outlet 413 and a flow area 436 near the cold compress assembly 300. The heat dissipation assembly 400 further includes a shielding portion 44, which shields the windshield area 435, allowing air between adjacent heat sinks 43 to flow out of or into the flow area 436 near the cold compress assembly 300.

[0159] This allows the air in the second heat dissipation duct 52 to flow closer to the cold compress assembly 300, thereby improving the heat dissipation effect on the cold compress assembly 300. Furthermore, since the deflection section 421 is deflected downward near the first air outlet 413, the shielding portion 44 can better prevent the deflection section 421 from directly directing the air flowing out of the first air outlet 413 toward the heat dissipation section 431.

[0160] In some embodiments, the shielding portion 44 at least shields the free side 434 of the heat dissipation section 431. Therefore, the shielding portion 44 can prevent the deflection section 421 from directly directing the air flowing out of the first air outlet 413 away from the heat dissipation section 431.

[0161] In some embodiments, the length of the shielding portion 44 along the first air outlet 413 toward the light output assembly 200 is more than one-third of the length of the heat sink 43 , so that the air between adjacent heat sinks 43 can flow out from the circulation area 436 near the cold compress assembly 300 .

[0162] 9 is a schematic diagram illustrating the structure of a first shielding portion at the heat sink of the skin treatment device shown in FIG2. In some embodiments, the shielding portion 44 may include a windshield 441 that covers the free sides 434 of the plurality of heat sinks 43.

[0163] Please continue to refer to Figure 10, which is a schematic diagram of the structure of the first type of shielding portion on the heat sink of the skin treatment device shown in Figure 2. In some embodiments, the shielding portion 44 may include multiple folded edges 442, each of which is bent and connected to the free side 434 of one of the heat sinks 43. Therefore, during the manufacturing process, the folded edges 442 can be directly formed on the free side 434 of the heat sink 43 through a bending or flipping process, making the manufacture of the heat sink 43 and the shielding portion 44 simpler and more cost-effective.

[0164] Specifically, the shielding portion 44 may include only one of the windshield 441 and the folded edge 442, or the shielding portion 44 may include both the windshield 441 and the folded edge 442 at the same time, which is not limited in the embodiment of the present application.

[0165] The housing 100 further includes a second air vent 13 connected to the outside of the housing 100 . The second air vent 13 is located on a side of the heat sink 43 facing away from the temperature plate 42 . The second air vent 13 corresponds to the shielding portion 44 and is connected to the circulation area 436 .

[0166] Thus, taking the first air outlet 413 as the outlet of the fan 41 as an example, the second portion of the air flowing out of the first air outlet 413 can be directly discharged from the second air outlet 13 after passing through the heat sink 43, thereby shortening the heat dissipation path of the second heat dissipation duct 52 and increasing the flow rate. Furthermore, since the second air outlet 13 is arranged corresponding to the shielding portion 44, it also means that the second air outlet 13 is further away from the light output area 11, thereby preventing the hot air discharged from the second air outlet 13 from directly blowing onto the skin to be treated near the light output area 11, thereby improving the user experience of the skin treatment device.

[0167] In some embodiments, a second anti-turbulence structure 45 is provided on a side of the heat sink 43 away from the temperature homogenizer 42 to limit turbulence from forming on the side of the heat sink 43 away from the temperature homogenizer 42 .

[0168] For example, the second anti-turbulence structure 45 is located in the circulation area 436 to limit the wind flowing out of the circulation area 436 from forming turbulence.

[0169] It is understandable that, because the height of the heat sink 43 gradually decreases from the near heat sink section 431 to the far heat sink section 432, or in other words, the space between the heat sink 43 gradually decreases, and the shielding portion 44 forces the second portion of wind to flow to the far heat sink section 432 before it can flow out, the flow area 436 at the far heat sink section 432 is prone to turbulence. In this case, by providing the second anti-turbulence structure 45, the wind flowing out of the flow area 436 can flow more smoothly, thereby improving the heat dissipation effect.

[0170] In some embodiments, each heat sink 43 is provided with a second anti-turbulence structure 45, so that the heat dissipation effect can be improved by providing more second anti-turbulence structures 45. Of course, in some other embodiments, only one or some of the heat sinks 43 may be provided with a second anti-turbulence structure 45, and this embodiment of the application is not limited to this.

[0171] In some embodiments, the second anti-turbulence structure 45 may include a plurality of teeth, which are protruding from the side of the heat sink 43 facing away from the heat spreader 42. Furthermore, compared to the flat side of the heat sink 43 facing away from the heat spreader 42, the teeth can effectively limit the formation of turbulence in the flow area 436.

[0172] In some embodiments, the second anti-turbulence structure 45 may include a plurality of teeth, each of which is triangular in shape. Of course, in other embodiments, the teeth may also be in other shapes, which is not limited in this embodiment of the present application.

[0173] In some embodiments, the second anti-spoiler structure 45 can be integrally formed with the heat sink 43. Of course, the second anti-spoiler structure 45 can also be separately formed from the heat sink 43, for example, the second anti-spoiler structure 45 can be detachably connected to the heat sink 43. This embodiment of the present application is not limited to this.

[0174] In some embodiments, the housing 100 further includes a second air vent 13 that communicates with the exterior of the housing 100. The second air vent 13 is located on the side of the heat sink 43 facing away from the temperature distribution plate 42. The end of the first heat dissipation duct 51 away from the first air vent 413 communicates with the second air vent 13 to connect to the exterior of the housing 100. The end of the second heat dissipation duct 52 away from the first air vent 413 communicates with the second air vent 13 to connect to the exterior of the housing 100.

[0175] Please continue to refer to Figures 11 and 12. Figure 11 is a cross-sectional view of the skin treatment device shown in Figure 2 along the BB direction, and Figure 12 is a cross-sectional view of the heat dissipation assembly and light output assembly shown in Figure 2. In some embodiments, the housing 100 further comprises a second air vent 13 that communicates with the exterior of the housing 100. The second air vent 13 is located on the side of the heat sink 43 facing away from the temperature evaporating plate 42. The inner wall of the housing 100 also comprises a third heat dissipation duct 57. One end of the third heat dissipation duct 57 communicates with the end of the first heat dissipation duct 51 distal from the first air vent 413. The other end of the third heat dissipation duct 57 and the end of the second heat dissipation duct 52 distal from the first air vent 413 are both connected to the second air vent 13, forming a Bernoulli structure at the connection point.

[0176] For example, the first air outlet 413 is the outlet of the fan 41. When the fan 41 is running, the pressure at the outlet of the first air duct with a faster flow rate between the third heat dissipation duct 57 and the second heat dissipation duct 52 will be lower, thereby drawing or sucking out the air in the second air duct, thereby increasing the flow rate in the second air duct and improving the overall heat dissipation effect of the skin treatment device.

[0177] For example, when the fan 41 is running, the air flow rate in the second heat dissipation duct 52 may be greater than the air flow rate in the third heat dissipation duct 57. Thus, the air in the second heat dissipation duct 52 carries out the air in the third heat dissipation duct 57, and the air in the second heat dissipation duct 52 indirectly carries out the air in the first heat dissipation duct 51.

[0178] In some embodiments, the outlet of the third heat dissipating air duct 57 at one end close to the second air outlet 13 is provided on the inner wall of the outlet end of the second heat dissipating air duct 52 , so as to facilitate the air in the second heat dissipating air duct 52 to carry out the air in the third heat dissipating air duct 57 .

[0179] In some embodiments, the second heat dissipation duct 52 extends from the first air outlet 413 to the second air outlet 13. The heat sink 43 is located within the second heat dissipation duct 52, and both the first air outlet 413 and the second air outlet 13 are adjacent to the heat sink 43, making the second heat dissipation duct 52 relatively short. The first heat dissipation duct 51 is located on the side of the vapor chamber 42 facing away from the second air outlet 13, so that the total length of the first portion of air flowing through the first heat dissipation duct 51 and the third heat dissipation duct 57 is greater than the total length of the second portion of air flowing through the second heat dissipation duct 52.

[0180] Please continue to refer to Figure 13, which is another cross-sectional view of the skin treatment device shown in Figure 1. The third heat dissipation duct 57 may include a pressure diffuser 571 and a connecting section 572. The pressure diffuser 571 communicates with the mounting section 511 through the mounting opening 516 (that is, the pressure diffuser 571 communicates with the mounting section 511 through the gap vents 212 and end vents 214 described below). One end of the pressure diffuser 571 extends away from the light exit area 11. The connecting section 572 is located on the side of the pressure diffuser 571 near the second air outlet 13. One end of the connecting section 572 communicates with the end of the pressure diffuser 571 away from the light exit area 11, and the other end of the connecting section 572 communicates with the inner wall of the second heat dissipation duct 52 near the second air outlet 13, so that both the first heat dissipation duct 51 and the second heat dissipation duct 52 are connected to the second air outlet 13, forming a Bernoulli structure at the connection point.

[0181] In this way, by setting up the diffusion chamber 571, the wind after blowing through the lamp tube and the reflective component 21 can enter a larger space after passing through the installation port 516 (that is, the gap air outlet 212 and the end air outlet 214 described below) to reduce wind resistance, so that the wind after blowing through the lamp tube and the reflective component 21 can enter the diffusion chamber 571 more smoothly through the gap air outlet 212 and the end air outlet 214 to improve the heat dissipation efficiency.

[0182] In some embodiments, the cross-sectional area of ​​the pressure diffusion cavity 571 may gradually decrease in a direction away from the light emitting region 11 , thereby making the gas flow rate in the pressure diffusion cavity 571 faster and improving the heat dissipation effect on the light emitting component 200 .

[0183] Accordingly, the circuit board 61 may form part of the inner wall of the pressure diffusion cavity 571 or be partially disposed in the pressure diffusion cavity 571 , so that the conductive bracket 62 is disposed in the pressure diffusion cavity 571 .

[0184] Therefore, since the total length of the first part of the wind flowing in the first heat dissipation duct 51 and the second heat dissipation duct 52 is large, the flow rate of the first part of the wind will be slower, so that the wind in the second heat dissipation duct 52 brings out the wind in the third heat dissipation duct 57, and finally the wind in the second heat dissipation duct 52 indirectly brings out the wind in the first heat dissipation duct 51.

[0185] Of course, in combination with the above-mentioned second heat dissipation duct 52, the height of the heat sink 43 gradually decreases from the near heat dissipation section 431 to the far heat dissipation section 432. Then, when the air intake of the second heat dissipation duct 52 is constant, the wind speed at the outlet of the second heat dissipation duct 52 will also be correspondingly faster, so that the wind in the second heat dissipation duct 52 brings out the wind in the third heat dissipation duct 57, and finally the wind in the second heat dissipation duct 52 indirectly brings out the wind in the first heat dissipation duct 51.

[0186] In some embodiments, the air intake volume at the inlet of the first heat dissipating air duct 51 is smaller than the air intake volume at the inlet of the second heat dissipating air duct 52, or in other words, the air intake volume at one end of the first heat dissipating air duct 51 connected to the first air outlet 413 is smaller than the air intake volume at one end of the second heat dissipating air duct 52 connected to the first air outlet 413, thereby making the wind speed at the outlet of the second heat dissipating air duct 52 greater, and then the wind in the second heat dissipating air duct 52 brings out the wind in the third heat dissipating air duct 57, and finally the wind in the second heat dissipating air duct 52 indirectly brings out the wind in the first heat dissipating air duct 51.

[0187] More importantly, in order to ensure the cooling effect of the cold compress assembly 300 and achieve a freezing point cooling effect, the heat generated by the cooling fins 32 needs to be discharged promptly and quickly. This requires ensuring that the second heat dissipation duct 52 has sufficient air volume and air speed to promptly and quickly remove the heat generated by the cooling fins 32 through the heat sink 43 and the temperature equalizer 42. That is, the present application makes the air volume at the inlet of the first heat dissipation duct 51 smaller than the air volume at the inlet of the second heat dissipation duct 52, so as to reasonably distribute the air volume of the fan, thereby achieving the ability to promptly and quickly remove the heat generated by the cooling fins 32 through the heat sink 43 and the temperature equalizer 42, thereby improving the cooling effect of the cold compress assembly 300 and achieving a freezing point cooling effect, such as quickly reducing the cooling temperature of the cold compress assembly 300 to zero degrees or below zero degrees (such as minus 5 degrees).

[0188] For example, one end of the first heat dissipating duct 51 close to the first air outlet 413 is the air inlet of the first heat dissipating duct 51, and one end of the first heat dissipating duct 51 close to the first air outlet 413 is the air inlet of the second heat dissipating duct 52; wherein, the area of ​​the corresponding region between the first air outlet 413 and the air inlet of the first heat dissipating duct 51 is smaller than the area of ​​the corresponding region between the first air outlet 413 and the air inlet of the second heat dissipating duct 52, so that the air intake volume at the entrance of the first heat dissipating duct 51 is smaller than the air intake volume at the entrance of the second heat dissipating duct 52.

[0189] Specifically, the first air outlet 413 includes a first side 411 proximate to the first heat dissipation duct 51 and a second side 412 proximate to the second heat dissipation duct 52. The first side 411 and the second side 412 are arranged opposite each other. The distance between the diverter structure 42a and the first side 411 is shorter than the distance between the diverter structure 42a and the second side 412. In other words, the distance between the end of the deflection section 421 proximate to the first air outlet 413 and the first side 411 is shorter than the distance between the end and the second side 412. As a result, the air intake at the inlet of the first heat dissipation duct 51 is smaller than the air intake at the inlet of the second heat dissipation duct 52.

[0190] Please refer to Figures 12 to 15. Figure 14 is a cross-sectional view of the skin treatment device shown in Figure 2 along the CC direction, and Figure 15 is a partial enlarged view of the Z point in Figure 14. In some embodiments, the inner wall of the first heat dissipation duct 51 is provided with a mounting opening 516. The light output assembly 200 is installed in the first heat dissipation duct 51 through the mounting opening 516 and forms a gap air outlet 212 with the inner wall of the mounting opening 516. The light output assembly 200 includes a reflective component 21 and a light source 22. The light source 22 is disposed in the reflective component 21. Side air outlets 213 are provided on the circumference of the reflective component 21, and the side air outlets 213 are connected to the first heat dissipation duct 51. The end of the reflective component 21 is also provided with an end air outlet 214.

[0191] Thus, taking the first air outlet 413 as the air outlet of the fan 41 as an example, a part of the wind in the first heat dissipation duct 51 can be blown directly to the surface of the reflective component 21, and the other part can be blown into the reflective component 21 to increase the heat dissipation area of ​​the light-emitting component 200, thereby improving the heat dissipation effect of the light-emitting component 200.

[0192] In some embodiments, the mounting opening 516 is connected to an end of the third cooling duct 57 that is close to the first cooling duct 51. The end of the third cooling duct 57 that is away from the first cooling duct 51 is connected to an end of the second cooling duct 52 that is away from the first air outlet 413. The end air outlet 214 is connected to the mounting opening 516 or the third cooling duct 57.

[0193] Thus, taking the first air outlet 413 as the air outlet of the fan 41 as an example, a part of the wind in the first heat dissipation duct 51 is directly blown to the surface of the reflective component 21 and then discharged through the gap air outlet 212, the third heat dissipation channel, the outlet end of the second heat dissipation channel and the second air outlet 13 in sequence; another part of the wind in the first heat dissipation duct 51 is directly blown to the interior of the reflective component 21 through the side air outlet 213 and then discharged through the end air outlet 214, the third heat dissipation duct 57, the outlet end of the second heat dissipation duct 52 and the second air outlet 13 in sequence.

[0194] In some embodiments, the end tuyere 214 and the gap tuyere 212 are disposed adjacent to each other to form a Benoulli structure.

[0195] For example, the light source 22 includes a lamp tube. The reflective component 21 is disposed on the outer periphery of the lamp tube. Along the length of the lamp tube, the end of the reflective component 21 extends through the mounting opening 516, and a gap vent 212 is formed between the outer wall of the reflective component 21 and the inner wall of the mounting opening 516. Along the length of the lamp tube, an end vent 214 is formed between the inner wall of the reflective component 21 and the lamp tube, so that the gap vent 212 and the end vent 214 form a Bernoulli structure.

[0196] For example, the first air outlet 413 is the outlet of the fan 41. When the fan 41 is running, the pressure at the outlet with the faster flow rate of the end air outlet 214 or the gap air outlet 212 will be lower, thereby drawing out or sucking out the air in the flow channel corresponding to the other outlet, thereby improving the overall heat dissipation effect of the skin treatment device.

[0197] Specifically, since the flow path of the wind flowing into the reflective component 21 is more tortuous and longer, when the fan 41 is running, the wind flow rate from the outside of the reflective component 21 to the gap air outlet 212 will be greater than the wind flow rate at the end air outlet 214, thereby bringing out the wind inside the reflective component 21.

[0198] Then, by continuing to combine the outlet of the second heat dissipation duct 52 and the outlet of the third heat dissipation duct 57 to form another Bernoulli structure, the skin treatment device in the embodiment of the present application can increase the flow speed of the wind inside the reflective component 21 through the double Bernoulli structure, thereby improving the heat dissipation effect.

[0199] In some embodiments, the number of gap vents 212 may be one or more. For example, at least one protrusion may be formed on the inner wall of the mounting opening 516, and the at least one protrusion may abut against the outer wall of the reflective component 21, so that the protrusion separates the inner wall of the mounting opening 516 from the outer wall of the reflective component 21 to form multiple or at least two gap vents 212.

[0200] In some embodiments, the light exit area 11 and the first air outlet 413 are located on different sides of the lamp tube in the circumferential direction and are arranged opposite to each other.

[0201] For example, the light emitting area 11 may be located at the front side of the lamp tube, and the first air outlet 413 may be located at the rear side of the lamp tube.

[0202] In some embodiments, both circumferential sides of the reflective component 21 form openings toward the light emitting area 11 to converge the light generated by the lamp toward the light emitting area 11, wherein at least one circumferential side of the reflective component 21 is provided with a side air outlet 213.

[0203] For example, both sides of the reflective component 21 may face forward, thereby forming a forward opening. In this case, the upper side and the lower side of the front side of the reflective component 21 may be provided with side vents 213 .

[0204] Specifically, the reflective component 21 may be a reflective cup.

[0205] In conjunction with the above-mentioned guide section 512 including a first inner wall 513 and a second inner wall 514, one side edge of the reflective component 21 in the circumferential direction is adjacent to the first inner wall 513, so that the first inner wall 513 directs a portion of the wind toward the adjacent side air outlet 213. Another side edge of the reflective component 21 in the circumferential direction is adjacent to the second inner wall 514, so that the second inner wall 514 directs a portion of the wind toward the adjacent side air outlet 213.

[0206] In some embodiments, the inner wall of the first heat dissipation duct 51 is provided with a mounting opening 516 at at least one end along the length of the lamp tube. The mounting openings 516 on different sides along the length of the lamp tube are connected to the second heat dissipation duct 52 through different third heat dissipation ducts 57 .

[0207] For example, if the length direction of the lamp tube is left-right, then both the left and right inner walls of the first heat dissipation duct 51 may be provided with a mounting opening 516 , and each mounting opening 516 is respectively matched with a third heat dissipation duct 57 .

[0208] Referring now to Figure 16 , Figure 16 is a schematic diagram of a first circuit board assembly of the skin treatment device shown in Figure 2 . In some embodiments, the skin treatment device further includes a circuit board assembly 600 , which includes a circuit board 61 and a conductive bracket 62 . Circuit board 61 is disposed within housing 100 . Conductive bracket 62 is mounted on circuit board 61 .

[0209] Correspondingly, the light output assembly 200 includes a light source 22 , which is mounted on a conductive bracket 62 to be supported by the conductive bracket 62 and electrically connected to the circuit board 61 .

[0210] For example, the light emitting assembly 200 may include a lamp tube, and an end portion of the lamp tube is connected to the conductive bracket 62 so that the lamp tube is supported on the circuit board 61 and electrically connected to the circuit board 61 .

[0211] In some embodiments, the circuit board 61 and the bracket assembly 500 form a third heat dissipation duct 57, and the conductive bracket 62 is located in the third heat dissipation duct 57, thereby fully utilizing the third heat dissipation duct 57 to install and fix the lamp tube, making the overall structure of the skin treatment device more compact.

[0212] In some embodiments, the number of the light sources 22 , such as light tubes, is at least two, and the at least two light sources 22 are arranged at intervals.

[0213] Furthermore, the skin care effect of the skin care device can be improved by emitting light from multiple light sources 22. For example, the multiple light sources 22 can be turned on and off synchronously, so that the light source assembly 22 can perform skin care at a higher maximum power, thereby improving the skin care effect of the skin care device. Alternatively, different light sources 22 can emit light individually or in combination, so that the light source assembly 22 can have at least three lighting modes, so that a more appropriate lighting mode can be adjusted according to the actual needs of the user, thereby improving the skin care effect of the skin care device.

[0214] Taking the example of multiple light sources 22 being able to switch on and off synchronously, the first ends of all light sources 22 may be mounted on the same conductive bracket 62 to be electrically connected to the circuit board 61 , and the second ends of all light sources 22 may be mounted on another conductive bracket 62 to be electrically connected to the circuit board 61 .

[0215] Specifically, the first end of the light source 22, such as a lamp, can be the positive electrode and the second end can be the negative electrode, or the first end of the light source 22, such as a lamp, can be the negative electrode and the second end can be the positive electrode. It can also be understood that the positive electrodes of all light sources 22 are electrically connected to the circuit board 61 via the same conductive bracket 62, and the negative electrodes of all light sources 22 are electrically connected to the circuit board 61 via another conductive bracket 62. This can make the current transmission between the circuit board 61 and all light sources 22 more consistent, thereby improving the consistency of light emission from all light sources 22, and ultimately further improving the skin care effect of the skin care device.

[0216] The following continues with the example that different light sources 22 can emit light individually or in combination to further explain and illustrate the technical solution of the embodiment of the present application.

[0217] Please continue to refer to Figure 17, which is a schematic diagram of a second circuit board assembly of the skin treatment device shown in Figure 2. The at least two light sources 22 may include a first light source 221 and a second light source 222. Therefore, at least three different light emission modes can be achieved using the first light source 221 and the second light source 222. Of course, the number of light sources 22 can also be three, four, five, or six. In this case, the first light source 221 and the second light source 222 can be any two of the plurality of light sources 22, and this is not limited in this embodiment of the present application.

[0218] The conductive bracket 62 includes a first conductive bracket 621, a second conductive bracket 622, and a third conductive bracket 623. The positive electrodes of the first light source 221 and the second light source 222 are both electrically connected to the third conductive bracket 623. The negative electrode of the first light source 221 is electrically connected to the first conductive bracket 621, and the negative electrode of the second light source 222 is electrically connected to the second conductive bracket 622.

[0219] Then, the third conductive bracket 623 can also be understood as a common positive pole, thereby reducing the number of conductive brackets 62 required between the light source 22 and the circuit board 61, so as to simplify the structure of the skin care device and reduce the assembly difficulty and production cost of the skin care device.

[0220] Here, it can also be understood that the circuit board 61, the third conductive bracket 623, the first light source 221, and the first conductive bracket 621 form a first loop, and the circuit board 61, the third conductive bracket 623, the second light source 222, and the second conductive bracket 622 form a second loop. In this way, by providing a switch at a corresponding position of the first conductive bracket 621 and another switch at a corresponding position of the second conductive bracket 622, independent control of the first light source 221 and the second light source 222 can be achieved.

[0221] Alternatively, the conductive support 62 may include a first conductive support 621, a second conductive support 622, and a third conductive support 623. The cathodes of the first light source 221 and the second light source 222 are both electrically connected to the third conductive support 623, the anode of the first light source 221 is electrically connected to the first conductive support 621, and the anode of the second light source 222 is electrically connected to the second conductive support 622.

[0222] Then, the third conductive bracket 623 can also be understood as a common negative pole, thereby reducing the number of conductive brackets 62 required between the light source 22 and the circuit board 61, so as to simplify the structure of the skin care device and reduce the assembly difficulty and production cost of the skin care device.

[0223] Here, it can also be understood that the circuit board 61, the third conductive bracket 623, the first light source 221, and the first conductive bracket 621 form a first loop, and the circuit board 61, the third conductive bracket 623, the second light source 222, and the second conductive bracket 622 form a second loop. In this way, by providing a switch at a corresponding position of the first conductive bracket 621 and another switch at a corresponding position of the second conductive bracket 622, independent control of the first light source 221 and the second light source 222 can be achieved.

[0224] Please continue to refer to Figure 18, which is a schematic diagram of a third circuit board assembly for the skin treatment device shown in Figure 2. Of course, in some other embodiments, there are multiple conductive brackets 62. Different light sources 22 are mounted on the circuit board 61 via different conductive brackets 62. This ensures that even if any conductive bracket 62 falls off or is damaged, the remaining conductive brackets 62 can still provide power to the corresponding light source 22, ensuring that the other light sources 22 in the skin care device can function properly. More importantly, this arrangement can increase light output power (e.g., hair removal power) and / or light output function diversity (e.g., hair removal function diversity). That is, by providing at least two light sources 22, each mounted and fixed to the circuit board 61 via different conductive brackets 62, when hair removal power is required, multiple light sources 22 can be activated simultaneously, while when not required, only one light source 22 can be activated. Alternatively, at least two of the at least two light sources 22 can be alternately illuminated, thereby increasing light output power while reducing or even eliminating the loss of a single light source 22.

[0225] In some embodiments, the light emitting assembly 200 further includes a reflective component 21 disposed around the lamp tube. The reflective component 21 is electrically connected to the circuit board 61, and the distance between the reflective component 21 and the lamp tube is less than a preset distance so that the reflective component 21 can excite the lamp tube.

[0226] For example, the lamp tube can be a xenon lamp tube, and the two ends or poles of the xenon lamp tube are electrically connected to the circuit board 61 through the conductive bracket 62. At this time, the circuit board 61 can excite or trigger the lamp tube through the reflective component 21, thereby reducing the components of the skin treatment device through the reuse of the reflective component 21, making the skin treatment device more compact.

[0227] In some embodiments, the preset distance may be less than or equal to 2 mm. For example, the distance between the reflective component 21 and the lamp tube is 2 mm, 1.4 mm, 0.5 mm, or 0 mm. Of course, when the distance between the reflective component 21 and the lamp tube is 0 mm, it can also be understood that the reflective component 21 and the lamp tube are directly in contact.

[0228] Optionally, in some embodiments, a wire (such as a filament) may be wound around the surface of the lamp tube, and the wire is electrically connected to the circuit board 61 for exciting the lamp tube, which is not limited in this embodiment of the present application.

[0229] In some embodiments, the circuit board assembly 600 further includes a spacer 63. The spacer 63 is positioned over at least one of the lamp and the conductive bracket 62, separating the reflective component 21 from the conductive bracket 62. The spacer 63 is spaced from the mounting opening 516 to form an air outlet gap. This spacer 63 prevents electrical leakage between the reflective component 21, which is used to excite the lamp, and the conductive bracket 62, thereby improving the reliability and safety of the skin treatment device.

[0230] The isolation member 63 may be made of an insulating material, such as plastic, rubber, ceramic, etc., which is not limited in the embodiment of the present application.

[0231] As shown in FIG13 , in some embodiments, the light emitting assembly 200 includes a lamp tube. The lamp tube is mounted on the mounting section 511. The inner wall of the guide section 512 also includes a third inner side wall 517 and a fourth inner side wall 518, and the third inner side wall 517 and the fourth inner side wall 518 are both connected between the first inner side wall 513 and the second inner side wall 514. The third inner side wall 517 and the fourth inner side wall 518 are respectively located at different ends in the length direction of the lamp tube. In particular, along the direction of the first air outlet 413 toward the light emitting assembly 200, at least one of the third inner side wall 517 and the fourth inner side wall 518 is tilted in a direction close to the other, so that the first part of the wind is directed toward the light emitting assembly 200.

[0232] It can be understood that in the actual working process, the main heat of the lamp tube is concentrated in the middle part of the lamp tube along the length direction. Then, taking the first air outlet 413 as the air outlet of the fan 41 as an example, the first part of the wind can be concentrated to the middle part of the lamp tube through the third inner wall 517 and the fourth inner wall 518, thereby achieving a better heat dissipation effect.

[0233] For example, in the length direction of the lamp tube, the length of the guide section 512 close to the light output component 200 is shorter than the length of the lamp tube, thereby concentrating the first part of the wind to the middle of the lamp tube through the third inner wall 517 and the fourth inner wall 518.

[0234] In some embodiments, the bracket assembly 500 further includes at least one third heat dissipation duct 57. The third heat dissipation duct 57 is provided on a side of the third inner sidewall 517 facing away from the fourth inner sidewall 518 and / or on a side of the fourth inner sidewall 518 facing away from the third inner sidewall 517. The third heat dissipation duct 57 extends from the first inner sidewall 513 toward the second inner sidewall 514. One end of the third heat dissipation duct 57 communicates with the outlet of the first heat dissipation duct 51. The other end of the third heat dissipation duct 57 communicates with the second heat dissipation duct 52.

[0235] Therefore, the avoidance space formed by the inward inclination of the third inner side wall 517 and / or the fourth inner side wall 518 can be fully utilized to arrange the third heat dissipation duct 57, so that the overall structure of the skin treatment device is more compact.

[0236] In addition, since the third inner wall 517 and the fourth inner wall 518 are inclined inward, the width of the third heat dissipation duct 57 can gradually decrease along the direction of the light output component 200 toward the first air outlet 413, thereby achieving an effect of pressurizing and accelerating the airflow.

[0237] Please continue to refer to Figure 19, which is a schematic diagram of the structure of the IGBT device in the skin treatment device shown in Figure 2. In some embodiments, the circuit board assembly 600 may also include an IGBT device 64. IGBT device 64 is mounted on the circuit board 61. The angle between one side surface of IGBT device 64 in the thickness direction and the circuit board 61 is greater than or equal to 45° and less than or equal to 90°.

[0238] For example, the angle between one side surface of the IGBT device 64 in the thickness direction and the circuit board 61 can be 45°, 49°, 57.8°, 66.9°, 75.4°, 85° or 90°, which is not limited in the embodiment of the present application.

[0239] Therefore, compared with the case where one side surface of the IGBT device 64 in the thickness direction is tightly attached to the circuit board 61, the embodiment of the present application forms a larger gap between the IGBT device 64 and the circuit board 61, thereby increasing the contact area between the IGBT device 64 and the air, and ultimately improving the heat dissipation effect of the IGBT device 64.

[0240] For example, the IGBT device 64 is vertically mounted on the circuit board 61 , so that the angle between one side surface of the IGBT device 64 in the thickness direction and the circuit board 61 is approximately equal to 90°.

[0241] In some embodiments, the fan 41 is used to drive the air in the housing to flow out of the air outlet on the housing 100 along a predetermined path. The IGBT device 64 is at least partially located in the predetermined path. Thus, the fan 41 can further improve the heat dissipation effect of the IGBT device 64.

[0242] For example, fan 41 can be mounted on circuit board 61. IGBT device 64 is positioned near fan 41. The air inlet of fan 41 can then draw in surrounding air, forming at least a portion of a predetermined path around the fan 41. Accordingly, by being positioned near fan 41, IGBT device 64 is at least partially positioned along the predetermined path.

[0243] In some embodiments, the circuit board 61 is disposed along the length of the housing 100. The circuit board 61 has a first side edge and a second side edge extending along the length direction. The IGBT device 64 is located between the fan 41 and the first side edge and is disposed adjacent to the first side edge.

[0244] The first side edge and the second side edge can be either the two side surfaces adjacent to the width direction of the housing 100 or the two side surfaces adjacent to the thickness direction of the housing. Furthermore, since the IGBT device 64 is positioned adjacent to the first side edge, the space between the fan 41 and the first side edge can be utilized to mount the IGBT device 64, thereby facilitating a compact design of the skin treatment device.

[0245] At this time, the above-mentioned IGBT device 64 is continued to be set close to the fan 41, and the IGBT device 64 can be installed vertically, so that the IGBT device 64 and the fan 41 are roughly at the same height, thereby rationally utilizing the space along the thickness direction of the shell 100 on the side of the fan 41 facing the first side edge, which is conducive to the miniaturized design of the skin treatment device.

[0246] In some embodiments, one side surface of the IGBT device 64 along the thickness direction may face the fan 41. It will be appreciated that due to the large size of the fan 41, the fan 41 occupies a correspondingly larger space along the length direction of the housing 100. In this case, positioning the IGBT device 64 with one side surface along the thickness direction facing the fan 41 effectively utilizes the space along the length direction of the housing 100 on the side of the fan 41 facing the first side edge, thereby facilitating a miniaturized design of the skin treatment device.

[0247] Please continue with Figure 20, which is a schematic diagram of the structure of an alternative fan for the skin treatment device shown in Figure 2. In some embodiments, the fan 41 can be arranged at an angle relative to the circuit board 61. Therefore, for example, if the fan 41 is installed on the upper side of the circuit board 61, a larger heat dissipation gap can be created between the bottom of the fan 41 and the circuit board 61. This allows more area on the upper surface of the circuit board 61 to be used for heat dissipation, wiring, or mounting electronic components, thereby facilitating a miniaturized design of the skin treatment device.

[0248] In some embodiments, the number of air inlets or third air outlets 414 of the fan 41 is at least two, and the third air outlet 414 is provided on the side of the fan 41 facing away from the circuit board 61, and the third air outlet 414 is provided on the side of the fan 41 close to the circuit board 61, thereby increasing the air intake volume of the fan 41 and improving the heat dissipation effect.

[0249] Please continue to refer to Figures 21 and 22. Figure 21 is a schematic structural diagram of the skin treatment device shown in Figure 1 from another perspective, and Figure 22 is a cross-sectional view of the skin treatment device shown in Figure 21 along the DD direction. In some embodiments, the housing 100 further includes a first display area 16, which has multiple indicators. The skin treatment device also includes a first light source assembly 613. The first light source assembly 613 is disposed within the housing 100 and is configured to generate light that is emitted from the first display area 16 to indicate the status of the skin treatment device. The first light source assembly 613 is configured to indicate whether the skin treatment device is in contact with the skin by turning it on and off, and is configured to display the gear position of the skin treatment device through an indicator displayed in the first display area 16. This makes it easier for the user to observe the usage status of the skin treatment device, improving the user experience. Furthermore, the number of light source assemblies in the skin treatment device can be reduced, thereby reducing the cost of the skin treatment device.

[0250] In some embodiments, the skin treatment device may also include a hair removal power control circuit for controlling the power of the light output assembly 200 or the gear position of the skin treatment device. The hair removal power control circuit is also electrically connected to the first light source assembly 613, so that the first light source assembly 613 can be configured to display the gear position information of the skin treatment device via an indicator displayed on the first display area 16.

[0251] In some embodiments, the skin treatment device may further include a hair removal power control circuit for controlling the power of the light output assembly 200 or the gear position of the skin treatment device. The hair removal power control circuit is also electrically connected to the first light source assembly 613, so that the first light source assembly 613 can be configured to display the gear position information of the skin treatment device via an indicator displayed on the first display area 16.

[0252] In some embodiments, the skin treatment device may further include a contact detection circuit. The contact detection circuit is used to detect whether the light-emitting area 11 is in contact with the skin. For example, the contact detection circuit includes a sensor for detecting whether the light-emitting area 11 is in contact with the skin. The sensor may be an electrode sheet, a proximity light sensor, a micro switch, an ultrasonic sensor, etc., and is not limited in this embodiment of the present application.

[0253] In some embodiments, the first display area 16 includes multiple first sub-display areas 161. The first light source assembly 613 includes multiple light-emitting devices. The first light source assembly 613 is configured to illuminate different numbers of first sub-display areas 161 by emitting light through different numbers of light-emitting devices, so that the first display area 16 displays different indication forms.

[0254] For example, the housing 100 may have a length, with multiple first sub-display areas 161 arranged along the length of the housing 100. Multiple light-emitting devices may also be arranged along the length of the housing 100, with each first sub-display area 161 corresponding to one or more light-emitting devices. By controlling the illumination of different light-emitting devices along the length of the housing 100, different numbers of first sub-display areas 161 may be illuminated, thereby causing the first display area 161 to display different indications.

[0255] In some embodiments, at least two functions can be indicated by the display of the first display area 16, such as indicating whether the light-emitting area 11 is in contact with the skin, and indicating gear information; that is, the first function (such as whether it is in contact with the skin) can be indicated by the lighting of the first display area 16, and the second function (gear) can be indicated by the display area / quantity / proportion of the first display area 16.

[0256] For example, when the light-emitting area 11 is in contact with the skin and the gear information of the skin treatment device is gear one, one first sub-display area 161 may be illuminated, causing the first display area 16 to display the first indication form. When the light-emitting area 11 is in contact with the skin and the gear information of the skin treatment device is gear two, two first sub-display areas 161 may be illuminated, causing the first display area 16 to display the second indication form. When the light-emitting area 11 is in contact with the skin and the gear information of the skin treatment device is gear three, three first sub-display areas 161 may be illuminated, causing the first display area 16 to display the third indication form. However, when the light-emitting area 11 is not in contact with the skin, all first sub-display areas 161 are off, that is, the first display area 16 is off, indicating that it is not in contact with the skin.

[0257] Alternatively, multiple first sub-display areas 161 may be arranged along any one of the circumferential direction or other curvilinear directions, which is not limited in this embodiment of the present application.

[0258] In some embodiments, the skin treatment device may further include a control button 700. The control button 700 is disposed on the housing 100 and partially exposed from the housing 100. The control button 700 is used to control the operation of the skin treatment device.

[0259] In some embodiments, the control button 700 and / or the area of ​​the housing 100 near the control button 700 is provided with a second display area 71 , and the second display area 71 is used to display whether the skin treatment device is connected to a power source.

[0260] This allows the user to conveniently observe the second display area 71 while controlling the skin treatment device via the control button 700 to confirm whether the skin treatment device is connected to a power source, thereby preventing the user from mistakenly believing that the skin treatment device is damaged or that the skin treatment has failed to complete. It should also be understood that when the second display area 71 is located near the control button 700, the number of openings on the surface of the housing 100 can be reduced, thereby making the appearance of the housing 100 more concise and aesthetically pleasing.

[0261] In some embodiments, the skin treatment device may further include a second light source assembly 616 . The second light source assembly 616 is disposed within the housing 100 . The second light source assembly 616 is configured to generate light for display in the second display area 71 .

[0262] For example, the second light source assembly 616 can be an LED lamp, a tungsten filament lamp, etc., which is not limited in this embodiment of the present application.

[0263] In some embodiments, the housing 100 has a length direction, and the housing 100 includes a panel 14 extending along the length direction. The first display area 16 and the second display area 71 are spaced apart and are both disposed on the panel 14 .

[0264] For example, the housing 100 may be in the shape of a long strip, and the first display area 16 and the second display area 71 may be located on the same side in the width or thickness direction of the housing 100. Therefore, when a user holds one end of the housing 100 in the length direction, the first display area 16 and the second display area 71 can be easily viewed.

[0265] It can also be understood that the second display area 71 is set on the panel 14. The second display area 71 can be directly formed on the panel 14, or the second display area 71 can be set on the control button 700, and the control button 700 is set on the panel and thus indirectly set on the panel 14. The embodiments of the present application do not limit this.

[0266] In some embodiments, the panel 14 may cover the first light source assembly 613 and / or the second light source assembly 616 . The panel 14 is partially light-transmissive to form the first display area 16 and / or the second display area 71 .

[0267] For example, the panel 14 may include a light-transmitting plate. The light-transmitting plate has a light-transmitting area and a light-shielding area. The light-shielding area is provided with a light-shielding structure such as a light-shielding layer, and the light-transmitting area forms the above-mentioned first display area 16 and / or second display area 71. Then, the light emission of the first light source assembly 613 and / or the second light source assembly 616 can be realized through the light-transmitting area, and the light generated by the first light source assembly 613 and / or the second light source assembly 616 can be irregularly diffused, and the structure around the first light source assembly 613 and / or the second light source assembly 616 can be shielded to improve the aesthetics of the housing 100.

[0268] In some embodiments, the light-transmitting area of ​​the panel 14 forms the first display area 16. The panel 14 may further have a mounting hole, through which the control button 700 is inserted, and the control button 700 has a second display area 71.

[0269] Alternatively, the first display area 16 and / or the second display area 71 may also be an opening structure on the surface of the housing 100 , which is not limited in the embodiment of the present application.

[0270] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0271] In some embodiments, the housing 100 has a length, a width, and a thickness. The light exit area 11 is located at one end of the housing 100. The length of the lamp tube is aligned with the width of the housing 100. The air inlet ends of the first and second heat dissipation ducts 51, 52 are spaced apart along the thickness of the housing 100. The housing 100 also has a back panel extending along the length. The back panel of the housing 100 is provided with a housing air inlet and a housing air outlet. The housing air inlet is connected to the air inlet of the fan 41, and the housing air inlet is connected to the air outlet ends of the first and second heat dissipation ducts 51, 52.

[0272] The above describes in detail the skin treatment device provided in the embodiments of the present application. The description of the above embodiments is intended only to facilitate understanding of the method and core concepts of the present application.

In summary, this specification should not be construed as limiting the present application.
