[0065] The skin treatment device of the embodiment is only described by taking the hair removal instrument as an example. In the use process of the hair removal instrument, the light generated by the light emitting device will bring a large amount of heat, and the cold compress assembly will also generate a certain amount of heat when working. If these heat cannot be dissipated in time, not only the use efficiency of the device will be reduced, but also the skin of the user may be uncomfortable. Therefore, in order to effectively dissipate heat, the existing design usually sets the air inlet and the air outlet on the same shell, and dissipates heat to the refrigeration part and the lamp tube through a complex internal air duct structure. In this design, the air inlet and the air outlet of the heat dissipation member need to be aligned with the air inlet and the air outlet on the shell respectively. In the assembly process, the two interfaces need to be accurately aligned, which increases the complexity and difficulty of assembly.

[0066] In order to solve the above problems, the skin treatment device 10 is provided in the present application, air inlets are arranged on two different shells, so that the complexity of assembly is reduced and the assembly efficiency is improved in the installation process. For details, please refer to Figures 1 to 4 .

[0067] The skin treatment device 10 of the embodiment of the present application comprises:

[0068] The shell 100 is provided with a first air inlet 101 on the side surface thereof;

[0069] The head cover 200 is connected with the shell 100, and the end of the head cover 200 opposite to the shell 100 is provided with a light emitting area 201. The side surface of the head cover 200 is provided with a second air inlet 202;

[0070] The light emitting device 300 is arranged in the head cover 200, and is used for generating light rays emitted to the skin to be treated through the light emitting area 201;

[0071] The cold compress assembly 400 is arranged at the light emitting area 201, and is used for cold compressing the skin to be treated;

[0072] The heat dissipation member 500 is installed in the shell 100 and / or the head cover 200, and the heat dissipation member 500 forms a heat dissipation air duct 600 with the head cover 200 and / or the shell 100. One end of the heat dissipation air duct 600 is communicated with the first air port 101, and the other end of the heat dissipation air duct 600 is communicated with the second air port 202.

[0073] The first air port 101 and the second air port 202 are respectively arranged on different housings. The first air port 101 is used for allowing external air flow to enter, and the second air port 202 is used for allowing air flow to carry heat generated by the light emitting device 300 and the cold compress assembly 400 to be discharged.

[0074] In the embodiment, the skin treatment device 10 includes a shell 100 (for example, made of plastic or metal material), a head cover 200 (which can include transparent or translucent material), a light emitting device 300 (for example, an LED lamp or a pulsed light source), a cold compress assembly 400 (for example, a semiconductor refrigeration sheet or a cooling gel sheet), and a heat dissipation member 500 (for example, a heat dissipation fan or a heat dissipation fin). The side of the shell 100 is provided with the first air port 101, which can be used as the air inlet of the device. The head cover 200 is connected to the shell 100, and the side of the head cover 200 is provided with the second air port 202, which can be used as the air outlet of the device.

[0075] The light emitting device 300 is arranged in the head cover 200 and used to generate light that is emitted through the light emitting area 201 to the skin to be treated. The cold compress assembly 400 is arranged at the light emitting area 201 and used to perform cold compress treatment on the skin when the light is emitted. The heat dissipation member 500 is installed in the shell 100 and / or the head cover 200, and the heat dissipation member 500 forms a heat dissipation air duct 600 with the head cover 200 and / or the shell 100. One end of the heat dissipation air duct 600 is communicated with the first air port 101, and the other end of the heat dissipation air duct 600 is communicated with the second air port 202. The air duct can be designed in a separate heat dissipation channel structure or a modular heat dissipation pipeline to ensure the effective flow of air in the device.

[0076] Referring to Figure 4 and Figure 5 In the assembly, first, the shell 100 and the head cover 200 are connected. The first air port 101 on the shell 100 only needs to be aligned with one end of the heat dissipation air duct 600, and the second air port 202 on the head cover 200 only needs to be aligned with the other end of the heat dissipation air duct 600. Since the first air port 101 and the second air port 202 are respectively arranged on two different housings, the alignment operation of each air port is more independent, which avoids the difficulty in alignment caused by the air inlet and the air outlet being arranged on the same housing. Next, the head cover 200 and the shell 100 are fixedly connected to complete the installation process. The whole process reduces the requirement for the precise alignment of the air inlet and the air outlet of the heat dissipation member 500, reduces the operation difficulty, and simplifies the assembly process.

[0077] The beneficial effect of the embodiment is that by setting the first air port 101 on the shell 100 and the second air port 202 on the head cover 200, the air inlet and outlet are located on different housings respectively, so that the installation process of each air port is relatively independent. Since only one end of the heat dissipation air duct 600 needs to be aligned during installation, the alignment difficulty during installation is greatly reduced, the required precision and time for assembly are reduced, the assembly efficiency is improved, and the production cost is reduced. In addition, due to the isolation design of the air duct, the heat dissipation effect is more obvious, and the overall working stability of the equipment is improved.

[0078] Referring to Figure 4 , Figure 5 and Figure 6 In the embodiment, the side of the shell 100 configured with the first air port 101 is further configured with a third air port 103, and the third air port 103 is located between the first air port 101 and the second air port 202.

[0079] The heat dissipation member 500 includes a fan 501, which is arranged in the shell 100. The air inlet of the fan 501 is in communication with the first air port 101.

[0080] The heat dissipation air duct 600 includes a first air duct 601 and a first branch air duct 602. One end of the first air duct 601 and the first branch air duct 602 is in communication with the air outlet 501a of the fan 501. The other end of the first air duct 601 is in communication with the second air port 202. The other end of the first branch air duct 602 is in communication with the third air port 103 and / or the second air port 202.

[0081] The skin treatment device 10 of the embodiment is further improved on the basis of the foregoing, and a third air port 103 is added to form a more effective heat dissipation and air flow management system.

[0082] Specifically, the skin treatment device 10 in the embodiment includes a shell 100, a head cover 200, a light emitting device 300, a cold compress assembly 400, a heat dissipation member 500, and three air ports. The side of the shell 100 is configured with a first air port 101 and a third air port 103, and the third air port 103 is located between the first air port 101 and the second air port 202. The head cover 200 is in abutment with the shell 100, and the side of the head cover 200 is provided with a second air port 202 for air outlet of the device. The light emitting device 300 is arranged in the head cover 200, for generating light rays emitted through the light emitting area 201 to the skin to be treated. The cold compress assembly 400 is located at the light emitting area 201, for cold compress treatment of the skin during light irradiation.

[0083] The heat dissipation component 500 comprises a fan 501 installed inside the housing 100, and the air inlet of the fan 501 is communicated with the first air inlet 101 to form the main air inlet system of the device. The heat dissipation air duct 600 comprises a first air duct 601 and a first branch air duct 602, one end of the first air duct 601 and the first branch air duct 602 are communicated with the air outlet 501a of the fan 501, the other end of the first air duct 601 is communicated with the second air inlet 202, and the other end of the first branch air duct 602 is communicated with the third air inlet 103 and / or the second air inlet 202. Through this structural design, a combined system of the main air duct and the branch air duct is formed.

[0084] In the embodiment, the first air inlet 101 can be used as an air inlet to provide cold air into the device, and the fan 501 distributes the air to the second air inlet 202 and the third air inlet 103 through the first air duct 601 and the first branch air duct 602. In this way, the addition of the third air inlet 103 can make the air flow form a gradually weakened air outlet effect, effectively optimizing the air flow distribution. That is, by adjusting the design of the air duct, the cold air is reasonably distributed through the first air duct 601 and the first branch air duct 602, ensuring that the air flow remains balanced during the discharge process at the second air inlet 202 and the third air inlet 103, which can avoid the phenomenon of heat backflow and improve the overall heat dissipation efficiency.

[0085] Further, as to how to realize the different air outlet effects of the two air inlets, the air inlet amount of the two air ducts can be considered. Specifically, referring to the above description of the air flow distribution of the device, the air flow distribution of the device can be adjusted by adjusting the air inlet amount of the two air ducts. Figure 6 In the embodiment, the air outlet amount of the third air inlet 103 is less than that of the second air inlet 202.

[0086] Further, the air outlet 501a of the fan 501 corresponds to one end of the first air duct 601.

[0087] Further, the communication area of the air outlet 501a of the fan 501 with the first air duct 601 is greater than that with the first branch air duct 602.

[0088] The skin treatment device 10 in the embodiment is further optimized in the design of the heat dissipation system to realize the effect that the air outlet amount of the third air inlet 103 is less than that of the second air inlet 202.

[0089] Specifically, the air outlet of the fan 501 corresponds to one end of the first air duct 601, which ensures that the main air flow is transported to the second air inlet 202 through the first air duct 601 to effectively discharge the heat inside the device. In addition, the communication area of the air outlet 501a of the fan 501 with the first air duct 601 is greater than that with the first branch air duct 602. This means that the air flow output by the fan 501 is mainly concentrated in the first air duct 601, and the air flow distributed to the first branch air duct 602 is relatively small, so that the air outlet amount of the third air inlet 103 is less than that of the second air inlet 202.

[0090] This structural design optimizes the air flow distribution path, so that the air flow ratio of the first air duct 601 and the first branch air duct 602 is controllable, and the air outlet control of different air outlets is realized. Specifically, by adjusting the communication area of the air outlet 501a of the fan 501, the first air duct 601 can obtain more air flow, ensuring that the second air outlet 202 has a larger air outlet to discharge more heat; while the first branch air duct 602 obtains relatively less air flow, which in turn causes the third air outlet 103 to have a smaller air outlet.

[0091] This embodiment effectively realizes the purpose of the third air outlet 103 having a smaller air outlet than the second air outlet 202. The air outlet 501a of the fan 501 corresponds to the first air duct 601, ensuring that the main air flow is concentrated in the path discharged through the first air duct 601, thereby improving the heat dissipation efficiency. At the same time, by controlling the communication area ratio of the fan 501 and each air duct, the distribution of air flow is further optimized, so that the air outlet of the third air outlet 103 forms a relatively gentle transition, avoiding the situation of heat backflow, and maintaining the stability of the cooling effect. In addition, it also prevents the air outlet of the third air outlet 103 from being too large, because it is close to the air inlet (first air outlet 101), so as to avoid that most of the air flow discharged by the third air outlet 103 is sucked into the machine again.

[0092] Further, the flow space of the first air duct 601 is larger than that of the first branch air duct 602.

[0093] This embodiment further optimizes the flow space of the heat dissipation air duct 600 on the basis of the aforementioned skin treatment device 10, to more effectively realize the air outlet control of different air outlets.

[0094] Specifically, the air outlet 501a of the fan 501 delivers the main air flow to the second air outlet 202 through the first air duct 601, while the first branch air duct 602 guides less air flow to the third air outlet 103. At the same time, the flow space of the first air duct 601 is increased, so that it can accommodate more air flow, ensuring that the second air outlet 202 obtains a larger air outlet, thereby effectively discharging the heat inside the device. The flow space of the first branch air duct 602 is relatively small, so that the air outlet of the third air outlet 103 is controlled at a low level, forming a smooth air flow transition.

[0095] Continue to refer to Figure 5 In this embodiment, the heat dissipation member 500 comprises:

[0096] The heat dissipation bracket 502 is installed in the shell 100 and / or the head cover 200, and is located between the cold compress assembly 400 and the fan 501;

[0097] The first heat dissipation fin 503 is at least partially installed in the first air duct 601.

[0098] The second heat dissipation fin 504 is at least partially installed in the first branch air duct 602.

[0099] The heat conduction member 505 is installed between the first heat dissipation fin 503 and the second heat dissipation fin 504 and is in heat conduction connection with the cold compress assembly 400.

[0100] The heat dissipation bracket 502 or the heat dissipation bracket 502 and the heat conduction member 505 form at least one of the first air duct 601 and the first branch air duct 602.

[0101] The heat dissipation member 500 of the skin treatment device 10 is improved in this embodiment, and the heat dissipation efficiency and air flow management are further improved by adding the heat dissipation bracket 502, the heat dissipation fin, and the heat conduction member 505.

[0102] Specifically, the heat dissipation bracket 502 is installed in the housing 100 and / or the head cover 200 between the cold compress assembly 400 and the fan 501. The heat dissipation bracket 502 provides support for the various components inside the device and also functions as a heat conductor and air flow guide. The heat dissipation bracket 502 is usually made of a metal material with good heat conduction performance (such as aluminum alloy or copper) to improve its heat conduction performance. Its design ensures that the heat generated by the cold compress assembly 400 can be quickly conducted to the heat dissipation fin so as to be carried away by the air flow blown by the fan 501.

[0103] The first heat dissipation fin 503 is at least partially installed in the first air duct 601, which is used to enhance the air flow cooling effect through the first air duct 601 and improve the heat dissipation efficiency. The first heat dissipation fin 503 has a multi-fin structure, and by increasing the surface area of the heat dissipation fin, more heat can be conducted into the air flow. The first heat dissipation fin 503 is directly connected to the heat dissipation bracket 502, and the heat captured by it is quickly discharged from the device through air flow.

[0104] The second heat dissipation fin 504 is at least partially installed in the first branch air duct 602, which is mainly used for auxiliary cooling to reduce the temperature of the air flow discharged through the first branch air duct 602. The volume of the second heat dissipation fin 504 is smaller than that of the first heat dissipation fin 503, and the main purpose is to form a temperature difference between the first air duct 601 and the first branch air duct 602 to ensure that the air flow discharged through the third air outlet 103 is not too hot. The second heat dissipation fin 504 can also increase the surface area to improve the heat dissipation effect, and is usually connected to the heat conduction member 505 to share the heat transfer path.

[0105] The heat-conducting member 505 is installed between the first heat sink 503 and the second heat sink 504 and is in heat-conducting connection with the cold compress assembly 400. The heat-conducting member 505 realizes heat transfer between the cold compress assembly 400 and the heat sinks through high-efficiency heat-conducting materials such as copper or aluminum, ensuring that heat is quickly conducted to the heat sinks and then taken away by the airflow in the air duct. The heat-conducting member 505 can be designed in a plate shape or a tube shape, ensuring that it occupies a small space in the device while having high-efficiency heat-conducting capacity.

[0106] The heat dissipation support 502 or the heat dissipation support 502 together with the heat-conducting member 505 forms at least one of the first air duct 601 and the first branch air duct 602. The main function of the first air duct 601 is to guide the airflow generated by the fan 501 to the second air outlet 202 for quickly discharging heat inside the device; the first branch air duct 602 is used to guide part of the airflow to the third air outlet 103 and / or the second air outlet 202 to achieve auxiliary heat dissipation. The arrangement of the first air duct 601 and the first branch air duct 602 ensures that the airflow flow path inside the device is more reasonable, improving the overall heat dissipation efficiency.

[0107] In this embodiment, the heat dissipation support 502 separates the cold compress assembly 400 from the fan 501, ensuring that the airflow flow path is clearer and effectively preventing heat accumulation. The first heat sink 503 and the second heat sink 504 are installed in different air ducts, forming an efficient heat dissipation system of the main air duct and the branch air duct. The multi-piece design of the first heat sink 503 makes it have a larger heat dissipation surface area, which can quickly transfer heat to the airflow. The heat-conducting member 505 realizes efficient heat transfer between different heat sinks and between the cold compress assembly 400, ensuring that the temperature of each light-emitting component can be lowered in time.

[0108] By reasonably combining the heat dissipation support 502, the heat-conducting member 505, the first heat sink 503, and the second heat sink 504, a compact and efficient heat dissipation system is formed. The heat dissipation support 502 and the heat-conducting member 505 together form an air duct structure, enabling the overall heat dissipation component 500 to realize compact design in a limited space while ensuring stable airflow and maximizing the heat dissipation effect. This design not only reduces temperature fluctuations inside the device but also further improves the stability of the device and the user experience.

[0109] In addition, the optimized design of the air duct structure makes the heat discharge path of the device more explicit, avoiding the mutual interference of heat between different components, ensuring that the cold compress assembly 400 and the light-emitting device 300 work in a relatively constant low-temperature environment, thereby improving the comfort and safety of the device.

[0110] Referring to Figure 7 , Figure 8 , Figure 9 , Figure 10and Figure 11 In this embodiment, the heat dissipation air duct 600 further comprises:

[0111] a second air duct 603, one end of the second air duct 603 is in communication with the air outlet 501a of the fan 501, the other end of the second air duct 603 is in communication with the second air outlet 202 and the other end of the first air duct 601, and the light emitting device 300 is located in the second air duct 603. The airflow flowing out of the air outlet 501a of the fan 501 passes through the light emitting device 300 in the second air duct 603 and is discharged from the second air outlet 202, thereby reducing the heat of the light emitting device.

[0112] Specifically, one end of the second air duct 603 is in communication with the air outlet 501a of the fan 501, and the other end is in communication with the second air outlet 202 and the other end of the first air duct 601. The light emitting device 300 is located in the second air duct 603, and the airflow passing through the second air duct 603 can directly cool the light emitting device 300, thereby effectively reducing the heat accumulation generated by its work. The design of the second air duct 603 ensures that the airflow can directly contact the surface of the light emitting device 300 and take away the generated heat, thereby improving the stability of the device and the quality of the light output.

[0113] The communication between the first air duct 601 and the second air duct 603: The communication between the first air duct 601 and the second air duct 603 enables the two airflow paths to work cooperatively. The first air duct 601 is mainly used to cool the cold compress assembly 400, while the second air duct 603 focuses on cooling the light emitting device 300. Through the joint design of the two air ducts, it is ensured that each light emitting component inside the device can be effectively cooled.

[0114] This embodiment significantly improves the heat dissipation performance of the skin treatment device 10 by adding the second air duct 603 and the flow guide assembly 510. The arrangement of the second air duct 603 enables the airflow to directly cool the light emitting device 300, ensuring that its temperature during work is maintained within a reasonable range, thereby improving the stability of the light output and the service life of the device. The light emitting device 300 is located in the second air duct 603 and can be directly exposed to the cooling airflow, reducing heat accumulation and improving the heat dissipation effect of the device.

[0115] Referring to Figure 9 , Figure 12 and Figure 13 Further, the heat dissipation member further comprises:

[0116] The fixed support 506 is arranged on the second heat sink 504, and one side wall of the fixed support 506 is provided with a first flow guide plate 511. The first flow guide plate 511 is located between the first heat sink 503 and the head cover 200 corresponding to the first heat sink 503. The first flow guide plate 511 is configured to at least partially isolate the gas in the second air duct 603 passing through the light emitting device 300 from contacting the first heat sink 503 and / or the second heat sink 504.

[0117] The skin treatment device in the embodiment adds a fixed support 506 arranged on the second heat sink 504, and a first flow guide plate 511 is arranged on one side wall of the fixed support 506. The design aims to optimize the gas flow path passing through the light emitting device 300, and avoid the influence of high-temperature gas flow on other heat dissipation components.

[0118] The first flow guide plate 511 in the embodiment can be manufactured by one-piece forming with the fixed support 506. This structure makes the fixed support 506 and the first flow guide plate 511 simultaneously formed during the manufacturing process, ensures the accurate position of the flow guide plate, and improves the strength and stability of the overall structure.

[0119] Of course, the first flow guide plate 511 can also be installed on the fixed support 506 as an independent component. The advantage of this modular design is that the angle and position of the flow guide plate can be more flexibly replaced or adjusted to adapt to different heat dissipation needs. For example, the flow guide plate can be fixed to the fixed support 506 by screwing or buckling, etc. connection method, so that the maintenance and replacement of the flow guide plate are more convenient.

[0120] Specifically, the first flow guide plate 511 is configured to be located between the first heat sink 503 and the head cover 200, and is mainly used to at least partially isolate the gas in the second air duct 603 passing through the light emitting device 300 (such as the light emitting device 300) from contacting the first heat sink 503 and / or the second heat sink 504. When the light emitting device 300 is working, the heat generated may be large, and the temperature of the gas flow in the second air duct 603 will also rise accordingly. If no effective isolation is performed, the hot gas flow may directly contact the first heat sink 503 and the second heat sink 504, thereby affecting the overall efficiency of the heat dissipation system.

[0121] Therefore, through the isolation effect of the first flow guide plate 511, the thermal load of the heat sink caused by the high-temperature gas flow can be effectively reduced. Specifically, through the isolation effect of the first flow guide plate 511, the high-temperature gas flow is guided away from the first heat sink 503 and the second heat sink 504, thereby forming a physical barrier to reduce the direct contact of heat convection. In this way, it is ensured that the high-temperature gas flow in the second air duct 603 does not directly contact the heat sink, effectively reducing the thermal load of the heat sink, reducing heat accumulation, and improving the overall heat dissipation efficiency of the device.

[0122] In this embodiment, the first flow guide plate 511 can isolate the high-temperature airflow in the second air duct 603 passing through the light-emitting device from the first and second heat sinks 503 and 504, reducing the chance of the heat sinks being directly exposed to the high-temperature airflow, thereby improving the cooling effect of the heat sinks. In addition, the one-piece structure design increases the overall stability and reliability, reduces the manufacturing cost and assembly complexity, and the modular assembly method provides more flexibility for adjustment and maintenance.

[0123] Referring to Figure 11 , Figure 12 and Figure 13 , in this embodiment, the heat dissipation member further comprises:

[0124] a second flow guide plate 512, the second flow guide plate 512 is connected with the side wall of the fixing bracket 506 or connected with the side wall of the first flow guide plate 511 and the side wall of the fixing bracket 506, and the second flow guide plate 512 is configured to guide the airflow of the second air duct 603 and the first air duct 601 to change the airflow direction, so that the airflow is changed to be discharged towards the housing and / or the head cover 200.

[0125] This embodiment mainly improves the heat dissipation system of the skin treatment device. Specifically, by providing the second flow guide plate 512, the airflow is better controlled, the heat dissipation effect of the device is improved, and the safety of the user is improved. The following describes two specific arrangement modes of the second flow guide plate 512, respectively discussing different connection modes of the second flow guide plate 512 and its functions.

[0126] In the first arrangement mode, the heat dissipation member of the skin treatment device comprises a second flow guide plate 512. The second flow guide plate 512 is connected with the side wall of the fixing bracket 506, and its main function is to change the direction of the hot airflow in the second air duct 603 passing through the light-emitting device 300. The light-emitting device 300 will generate a large amount of heat, resulting in a high temperature of the airflow in the second air duct 603. Through the guidance of the second flow guide plate 512, the high-temperature airflow is changed in direction, so that it is discharged towards the housing and / or the head cover 200, avoiding the hot airflow directly blowing to the user's hand.

[0127] In the second arrangement mode, the second flow guide plate 512 is connected with the side wall of the first flow guide plate 511 and the side wall of the fixing bracket 506, which has both isolation and guidance functions.

[0128] Specifically, the second flow guide plate 512, when connected with the side wall of the first flow guide plate 511 and the fixed support 506, can play an isolation role. That is, the second flow guide plate 512 at least partially isolates the high-temperature airflow passing through the light-emitting device 300 in the second air duct 603 from directly contacting the first heat sink 503 and / or the second heat sink 504, which can effectively prevent the high-temperature airflow from affecting the cooling effect of the heat sink and improve the overall heat dissipation performance of the device.

[0129] In addition to the isolation function, the second flow guide plate 512 also has the function of guiding the airflow direction. That is, by changing the path of the airflow, the second flow guide plate 512 ensures that the airflow is discharged to the outer shell and / or the head cover 200, avoiding the hot airflow directly blowing to the user's hand, reducing the risk of burns. This design can make the device safer during use and improve the user's experience.

[0130] In this way, in the first arrangement, the second flow guide plate 512 is used to guide the hot airflow in the second air duct 603, ensuring that it is quickly discharged outside the device, while avoiding the hot airflow directly blowing to the user's hand, reducing the risk of burns. In the second arrangement, the second flow guide plate 512 cooperates with the first flow guide plate 511 to not only isolate the high-temperature airflow from contacting the heat sink, but also change the airflow direction, avoiding the user being directly affected by the high-temperature airflow when operating the device. These improvements help to improve the heat dissipation performance and safety of the device.

[0131] Continuing to refer to Figure 13 In this embodiment, the second flow guide plate 512 is connected with the side wall of the first flow guide plate 511 and the fixed support 506, and is arranged at an obtuse angle with the side wall of the first flow guide plate 511 and the side wall of the fixed support 506. The second flow guide plate 512 is configured to guide the airflow of the second air duct 603 and the first air duct 601 to be discharged from the second air outlet.

[0132] In this embodiment, the second flow guide plate 512 is not only connected with the first flow guide plate 511 and the fixed support 506, but also connected at an obtuse angle with them, thereby forming an effective barrier. This isolation design can partially isolate the high-temperature airflow passing through the light-emitting device 300 in the second air duct 603 from directly contacting the first heat sink 503 and the second heat sink 504.

[0133] The second flow guide plate 512 also has the function of guiding the direction of the airflow while isolating the high-temperature airflow. Since the second flow guide plate 512 is connected at an obtuse angle with the first flow guide plate 511 and the fixed support 506, it can ensure that the airflow changes direction smoothly when passing through the flow guide plate. At the same time, the main purpose of the obtuse angle is to reduce resistance and turbulence when the airflow changes direction, so that the high-temperature airflow flows smoothly and is smoothly discharged from the device. The obtuse angle can also make the airflow turn more gently, avoiding turbulent flow and energy loss caused by sharp turns, thereby reducing the impact on the airflow speed and improving the heat dissipation efficiency. In this way, the airflow direction can be effectively guided, and the airflow can be ensured to flow smoothly.

[0134] The obtuse angle design of the second flow guide plate 512 in this embodiment achieves effective isolation and guidance of the airflow. The second flow guide plate 512 isolates the high-temperature airflow generated in the second air duct 603 from the heat dissipation fins, preventing the high-temperature airflow from negatively affecting the cooling effect of the heat dissipation fins. In addition, the airflow is guided to be discharged through the second air outlet, avoiding direct contact of the hot airflow with the user's hand, and reducing the risk of burns.

[0135] Continuing to refer to Figure 11 In this embodiment, the end of the head cover 200 opposite the light-out area 201 at least partially extends into the housing 100;

[0136] The side of the fixed support 506 opposite the heat dissipation support 502 is configured with a limiting portion 506a. When the head cover 200 is connected to the housing 100, the limiting portion 506a is used to limit the length of the head cover 200 extending into the housing 100.

[0137] The skin treatment device 10 in this embodiment adds a limiting portion 506a to the assembly design of the head cover 200 and the housing 100. The limiting portion 506a is provided on the fixed support 506 and used to position and limit during the connection of the head cover 200 and the housing 100.

[0138] Specifically, the end of the head cover 200 opposite the light-out area 201 at least partially extends into the housing 100. This design can make the connection between the head cover 200 and the housing 100 more secure, avoiding airflow leakage or structural looseness due to improper assembly.

[0139] The fixed support 506 is mounted on the heat dissipation support 502 and provides support for various components inside the device. The fixed support 506 is provided with a limiting portion 506a on the side opposite the heat dissipation support 502. The limiting portion 506a is used to limit the length of the head cover 200 extending into the housing 100 during the assembly of the head cover 200 and the housing 100.

[0140] The design of the limiting portion 506a can be a protruding structure or other forms, and the main function is to effectively control the assembly depth of the head cover 200 and the shell 100. When the head cover 200 and the shell 100 are docked, the limiting portion 506a serves as a physical limit to ensure that the head cover 200 can only extend into the shell 100 to a set length position. This design effectively avoids equipment installation problems caused by excessive insertion or insufficient insertion during assembly.

[0141] To further optimize the assembly efficiency, the assembly precision and the operation convenience of the head cover 200 and the shell 100 can be improved by adding the guide portion 502a on the heat dissipation support 502. For details, please refer to Figure 12 , at least one side wall of the heat dissipation support 502 is provided with the guide portion 502a, and the guide portion 502a is configured to guide the movement of the head cover 200 relative to the shell 100 when the head cover 200 and the shell 100 are docked.

[0142] In this embodiment, at least one side wall of the heat dissipation support 502 is provided with the guide portion 502a. The guide portion 502a can be a protruding sliding rail, a notch or other guide structure, which functions to provide an accurate movement path for the docking process of the head cover 200 and the shell 100.

[0143] When the head cover 200 and the shell 100 are docked, the guide portion 502a can guide the head cover 200 to move along the correct path to ensure that its positioning relative to the shell 100 is more accurate. The arrangement of the guide portion 502a can effectively reduce the offset and misalignment during assembly, so that the head cover 200 and the shell 100 are more smoothly combined, improving the success rate of assembly and the overall structural stability.

[0144] In this embodiment, the guide portion 502a can work in cooperation with the limiting portion 506a designed before. The guide portion 502a first ensures that the movement path of the head cover 200 relative to the shell 100 is correct and controlled, preventing the head cover 200 from being laterally misaligned during docking; and the limiting portion 506a limits the head cover 200 when it reaches the predetermined position, ensuring that the insertion depth of the head cover 200 is just right. This cooperative design makes the assembly process of the head cover 200 and the shell 100 more smooth and efficient.
