[0002] A hair removal device is a comfortable, safe, and stylish home hair removal instrument. It uses advanced phototherapy technology to effectively prevent hair regrowth on various parts of the body, achieving permanent hair removal.

[0003] In existing technologies, hair removal devices typically include a heat dissipation device. The heat dissipation performance of this device directly affects the cooling effect and durability of the device. However, the heat dissipation performance of traditional hair removal devices is poor, reducing the device's durability. Although some hair removal devices on the market have an independent air intake channel, the airflow from a single channel is insufficient to meet the heat dissipation needs of the device's internal mechanisms. Furthermore, due to the limitations of the heat dissipation device's structure, it cannot effectively dissipate heat from the internal components, resulting in poor heat dissipation performance.

[0029] Compared with the prior art, the hair removal device provided by the present invention has the following beneficial effects: (1) The hair removal device provided by the present invention includes two independent air inlet channels. By opening two independent air inlets on the fan housing, two independent air inlets are constructed to achieve simultaneous air intake and heat dissipation of the cooling component and the heating component. This solves the problem of not being able to simultaneously dissipate heat from multiple heating components, thereby enhancing the heat dissipation performance of the hair removal device and improving its durability and safety. The fan in the fan housing rotates and draws air, causing the air to form a fast-flowing airflow. The flowing airflow flows in through the first air inlet channel and the second air inlet channel, which greatly increases the amount of air entering the internal mechanism of the hair removal device per unit time. The strong and sufficient airflow can promptly remove the heat from the heating component and the cooling component inside the hair removal device and discharge it through the air outlet on the second housing of the hair removal device, further improving the heat dissipation performance of the hair removal device. Furthermore, the first air inlet channel and the second air inlet channel are independent of each other. The airflow through the first air inlet channel will draw air from the cooling component located at the first air inlet. The heat carried away by the first and second air intake channels accelerates the cooling of the refrigeration components, thereby removing heat from the heat-conducting substrate and cooling pad connected to the refrigeration components. This improves the cooling efficiency of the cooling pad, resulting in a better cooling effect during use and enhancing the user experience. Furthermore, the external air drawn into the second air intake channel passes through the heating components and carries away heat from them and the heat sink, accelerating their cooling. Essentially, the independent first and second air intake channels dissipate heat from different parts of the refrigeration device through airflow, ensuring that heat from all components inside the device is promptly removed. This further improves the heat dissipation performance, significantly enhancing the device's durability and ease of use. The improved heat dissipation also lowers the operating temperature of the refrigeration device, preventing overheating and ensuring a better user experience.

[0030] (2) In the hair removal device provided by the present invention, the heat pipe is connected to the cooling plate through a heat-conducting substrate. The heat-conducting substrate is made of a heat-conducting material. The heat-conducting substrate transfers the heat generated by the heating surface of the cooling plate to the heat pipe through contact heat dissipation. The heat pipe can absorb the heat generated by the heating surface of the cooling plate more in a timely manner, thereby improving the cooling efficiency of the cooling surface of the cooling plate. By setting the cooling component at the first air inlet, the heat in the heat pipe and heat sink is absorbed by the air and then discharged from the hair removal device in a timely manner by the fan rotation. This improves the heat dissipation efficiency of the cooling component and effectively avoids the heating component from affecting the normal operation of the hair removal device due to overheating, thereby further improving the stability of the hair removal device.

[0031] (3) In the hair removal device provided by the present invention, the heat dissipation component corresponding to the heating component is provided with multiple sheet-like mechanisms. The heat generated by the heating component is conducted to the heat dissipation component, and heat dissipation gaps are formed between the sheet-like mechanisms of the heat dissipation component. The heat dissipation gaps can effectively increase the contact area between the heat dissipation component and the air, so that the heat in the heat dissipation component can be efficiently absorbed by the air, thereby improving the heat dissipation performance of the heat dissipation component. Similarly, the heat dissipation fin assembly sleeved on the heat pipe includes at least two heat dissipation fins arranged at intervals. Air passage gaps are formed between adjacent heat dissipation fins. The air passage gaps between the heat dissipation fins also play the role of increasing the contact area between the heat dissipation fins and the air, so that the heat transferred from the heat pipe to the heat dissipation fin assembly can be absorbed by the air in time, thereby improving the heat dissipation performance of the heat pipe. This improves the heat dissipation efficiency of the heating surface of the cooling plate, enhances the cooling effect of the cooling plate, and strengthens the practicality of the hair removal device.

[0032] (4) In the hair removal device provided by the present invention, an annular air inlet gap is left between the first housing and the annular housing for air intake, and an air inlet hole is provided at the corresponding first air inlet on the outer shell for air intake. The air inlet hole and the air inlet gap can simultaneously allow air intake, increasing the air intake volume and improving the heat dissipation performance. The air outside the hair removal device is drawn into the hair removal device through the air gap and the air inlet hole, and finally the airflow formed by the hot air is blown out from the air outlet on the fan housing and discharged outside the hair removal device through the air outlet on the outer shell. It can be understood that the external air is drawn into the hair removal device through the air inlet gap and the air inlet hole by the rotation of the fan, and the drawn air is used for hair removal. The airflow between the internal mechanisms of the device absorbs heat from each other and is eventually discharged through the air outlet, achieving the function of air circulation and heat dissipation. This effectively prevents damage to the components in the device due to overheating, enhances the durability of the device, and makes it more practical. Furthermore, the external air drawn in through the air inlet gap blows along the inner wall of the first shell, and the continuous airflow promptly carries away the heat from the first shell and the air inlet cavity, keeping the temperature of the first shell stable and preventing overheating. This avoids discomfort caused by the user's skin coming into contact with an overheated first shell and effectively optimizes the user's hair removal experience.

[0033] (5) In the hair removal device provided by the present invention, the light-transmitting crystal is made of sapphire. Sapphire has the advantages of high thermal conductivity and high light transmittance. Due to the high thermal conductivity of sapphire, the light-transmitting crystal made of sapphire has excellent heat conduction and heat storage properties. The light-transmitting crystal is cooled by the cooling plate. The light-transmitting crystal made of sapphire can effectively apply ice to the user's skin by utilizing its excellent heat conduction and heat storage properties, thereby relieving the pain and burning sensation of the user's skin during hair removal. The user's experience when removing hair through the hair removal device is thus optimized.

[0034] (6) In the hair removal device provided by the present invention, the position of the air inlet hole on the outer shell for drawing in external air can be flexibly set according to actual needs. It is only necessary to meet the condition that the air inlet hole is connected to the air inlet cavity. The main advantage of this design is its flexibility. Manufacturers can adjust the position and shape of the air inlet hole according to the needs of customers to meet the aesthetics of different customers.

[0035] (7) In the hair removal device of the present invention, by sequentially arranging the light-transmitting crystal, the light-filtering lens, the light-shielding sheet, the heating element and the heat dissipation element in the heat dissipation housing, the stability of the light-emitting head assembly of the hair removal device is effectively enhanced, avoiding the malfunction caused by the loosening of internal parts during use, thus improving the safety of the hair removal device; and by setting a silicone sealing ring for sealing between the light-transmitting crystal and the light-filtering lens, the light-transmitting crystal, the silicone sealing ring and the light-filtering lens form a sealed cavity. During the pressing and installation process, the air in the sealed cavity is squeezed out, so that a vacuum is formed between the light-transmitting crystal and the light-filtering lens, avoiding the problem of air between the light-filtering lens and the light-transmitting crystal condensing into water droplets and causing electric shock to the human body, thus further improving the safety performance of the hair removal device.

[0036] (8) The hair removal device provided by the present invention uses a suction method to dissipate heat from the heating and cooling components. Under the action of the fan rotation, the ambient temperature air first passes through the heating and cooling components to remove the heat from them. Then, the air that has absorbed the heat is drawn into the fan housing and finally discharged from the outer shell of the hair removal device by the fan. Traditional blower cooling uses the fan rotation to blow air to form a high-speed airflow, which is used to blow high-heat components to achieve the purpose of heat dissipation. However, while the high-speed airflow removes the heat from the high-heat components, it also forms a high-temperature airflow. If the high-temperature airflow blows on a certain local area inside the hair removal device for a long time, it will cause the temperature of that area to rise sharply, eventually leading to overheating and damage to the components in that area. The suction cooling method used in the present invention uses a fan to blow air to remove heat from the components. The device directly draws the hot airflow past the high-heat components (i.e., the heating and cooling components) into the fan housing, preventing the hot airflow from lingering excessively within the internal structure of the hair removal device. Furthermore, the unique structure of the fan housing causes the hot airflow flowing through the second air inlet channel to converge in the air guide mechanism (i.e., the air guide mechanism restricts the hot airflow). Since there are no critical or easily damaged components near the air guide mechanism, even if the temperature of the air guide mechanism rises, it will not damage nearby components. It is understood that, compared to traditional blower-based heat dissipation methods, this invention's fan-assisted heat dissipation method avoids the problem of heat concentration leading to excessively high local temperatures and damage to components in the hair removal device, further improving the durability and safety of the device.

[0037] (9) When the fan assembly is used in the main body of the hair removal device, the cooling assembly is placed at the first air inlet, and the air circulates between the heating assembly and the second air inlet. This allows the fan assembly a to simultaneously draw in and dissipate heat from both the heating and cooling assemblies. Furthermore, external air passing through the cooling assembly is drawn into the fan housing through the first air inlet and discharged through the first air outlet. Similarly, external air passing through the heating assembly is drawn into the fan housing through the second air inlet and discharged through the second air outlet, thus achieving the purpose of discharging hot air. Moreover, since the first and second air chambers are independent of each other, the air output from the first and second air outlets is more efficient. To ensure smooth airflow and prevent turbulence from affecting air output efficiency due to simultaneous air intake from the first and second air inlets; furthermore, ambient temperature air from outside is drawn into the first air cavity through the first air inlet after passing through the cooling components, thereby absorbing and dissipating heat from the cooling components located at the first air inlet; the air inlet holes on the heat dissipation housing, the air guide mechanism, and the second air inlet on the fan housing are sequentially connected, making the air intake of the second air intake channel smoother, and ambient temperature air from outside is drawn into the second air cavity through the second air inlet after passing through the heating components, thereby absorbing and dissipating heat from the heating components in the air cavity, achieving the purpose of bidirectional air intake and heat dissipation.

[0038] (10) The first air chamber and the second air chamber are independent of each other, so that the rotation of the first fan blade and the second fan blade does not affect each other, thus improving the suction efficiency; the isolation plate mechanism is provided with a motor mounting slot, and the motor is located in the motor mounting slot. This structure saves the installation space of the motor, making the fan assembly smaller and saving the space occupied by the main body of the hair removal device; the second fan blade includes several second blades, which are spirally distributed around the axis of rotation and opposite to the orientation of the first blade. When the motor axis rotates, the first fan blade and the second fan blade rotate in the same direction at the same time. Since the first blade of the first fan blade and the second blade of the second fan blade are opposite in orientation, the first fan blade and the second fan blade can also suction air at the same time when they rotate in the same direction; it can be understood that by setting the first fan blade and the second fan blade with opposite blade orientation, the fan assembly can achieve bidirectional suction air through one motor and two fan blades. Compared with the traditional fan assembly structure that achieves bidirectional suction air by two motors and two fan blades, it is simpler and reduces the manufacturing cost.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific inventions described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0042] Please refer to the following: Figures 1-9 The first embodiment of the present invention provides a hair removal device 10, which includes a main body 11. The main body 11 includes a fan 12, a fan housing 13, a light-transmitting crystal, a cooling component 100, and a heating component 18. The fan housing 13 further includes a fan outer shell 130, a first air inlet 131 on one side of the fan outer shell 130, and at least one second air inlet 132 on the opposite side of the first air inlet 131. An air outlet 133 is opened on the outer periphery of the fan outer shell 130. The cooling component 100 is connected to the light-transmitting crystal and is located at the first air inlet 131. The heating component 18 is connected to the second air inlet 132. Air circulates through the inlet 132; the fan 12 is located in the fan housing 130 and rotates to draw in air, and external air is drawn into the fan housing 130 from the first air inlet 131 and the second air inlet 132 and discharged from the air outlet 133; the fan housing 13 further includes an air guiding mechanism 134, which has a structure with both ends interconnected and narrow in the middle and wide at both ends; the hair removal device body 11 further includes a heat dissipation housing 14, one end of the air guiding mechanism 134 is connected to the second air inlet 132, and the other end of the air guiding mechanism 134 is connected to the heat dissipation housing 14 and defines an air passage cavity 19, and the heating element 18 is located in the air passage cavity 19.

[0043] Specifically, external air is sequentially drawn into the fan housing 13 after passing through the air inlet 1522 and the cooling component 100 to define the first air inlet channel, thereby reducing the temperature of the cooling component 100. The heat dissipation housing 14 is provided with an air inlet 141, and is connected to the fan housing 13 to define an air passage 19. The heating component 18 is disposed in the air passage 19. External air is sequentially drawn into the fan housing 13 after passing through the air inlet 141 and the heating component 18 to define the second air inlet channel, thereby reducing the temperature of the heating component 18. The first air inlet 131 and the second air inlet 132 on the fan housing 130 are sequentially connected, making the air intake of the first air inlet channel smoother, so as to draw in air and dissipate heat from the cooling component 100 located at the first air inlet 131. The heat dissipation housing 14 is provided with at least one air inlet 141. The air inlet 141 on the heat dissipation housing 14, the air guide mechanism 134, and the second air inlet on the fan housing 130 are all connected. The sequential connection of 132 allows for smoother airflow into the second air intake channel, facilitating the cooling of the heating element 18 in the air passage 19. It is understood that by creating two independent air intake ports on the fan housing 130 to construct two independent air intake channels, simultaneous cooling of the cooling component 100 and the heating component 18 is achieved, solving the problem of simultaneously cooling multiple heating components. This enhances the heat dissipation performance of the hair removal device 10, improving its durability and safety. The rotation of the fan 12 in the fan housing 13 creates a rapidly flowing airflow. This airflow flows through the first and second air intake channels, significantly increasing the amount of air entering the internal structure of the hair removal device 10 per unit time. This powerful and sufficient airflow effectively removes heat from the heating components and cooling component 100 within the hair removal device 10, further improving its heat dissipation performance.

[0044] Furthermore, the hair removal device 10 provided by this invention uses a suction method to dissipate heat from the heating element 18 and the cooling element 100. Under the action of the rotating fan 12, ambient air first passes through the heating element 18 and the cooling element 100 to remove heat from them. Then, the air that has absorbed heat is drawn into the fan housing 13 and finally discharged from the outer shell 15 of the hair removal device 10 through the fan 12. Traditional blower cooling uses the rotating fan 12 to create a high-speed airflow, which is then used to blow heat from high-heat components to achieve heat dissipation. However, while the high-speed airflow removes heat from the high-heat components, it also creates a hot airflow. If this hot airflow blows on a localized area inside the hair removal device 10 for a prolonged period, the temperature in that area will rise sharply, eventually causing overheating and damage to the components in that area. The suction cooling method used in this invention, however, dissipates heat through... The fan 12 draws the hot airflow, which passes through the high-heat components (i.e., the heating element 18 and the cooling element 100), directly into the fan housing 13. This prevents the hot airflow from lingering excessively within the internal structure of the hair removal device 10. Furthermore, due to the unique structure of the fan housing 13, the hot airflow flowing through the second air inlet channel converges into the air guide mechanism 134 (i.e., the air guide mechanism 134 restricts the hot airflow). Since there are no important or easily damaged components near the air guide mechanism 134, even if the temperature of the air guide mechanism 134 rises, it will not cause damage to nearby components. It can be understood that, compared to the traditional blower cooling method, the heat dissipation method using the fan 12 in this invention avoids the problem of heat concentration and excessively high local temperatures that can easily lead to overheating and damage to components in the hair removal device 10, thus further improving the durability and safety of the hair removal device 10.

[0045] Please refer to the following: Figure 4 and Figure 5The main body 11 of the hair removal device further includes a light-transmitting crystal 20, a filter lens 22, a light-shielding sheet 23, and a heat sink 104. The light-transmitting crystal 20, the filter lens 22, the light-shielding sheet 23, the heating element 18, and the heat sink 104 are sequentially stacked and pressed together in the heat sink housing 14. A silicone sealing ring 21 is provided between the light-transmitting crystal 20 and the filter lens 22 to define a sealed cavity 24. By sequentially stacking and pressing the light-transmitting crystal 20, the filter lens 22, the light-shielding sheet 23, the heating element 18, and the heat sink 104 in the heat sink housing 14, the stability of the internal parts of the hair removal device 10 is effectively enhanced, avoiding problems during use. The loosening of internal parts prevents malfunctions and improves the safety of the hair removal device 10. Furthermore, by setting a silicone sealing ring 21 between the light-transmitting crystal 20 and the filter lens 22, the light-transmitting crystal 20, the silicone sealing ring 21, and the filter lens 22 form a sealed cavity 24. During the pressing and installation process, the air in the sealed cavity 24 is squeezed out, creating a vacuum between the light-transmitting crystal 20 and the filter lens 22. This prevents the air between the filter lens 22 and the light-transmitting crystal 20 from condensing into water droplets and causing electric shock, further enhancing the safety performance of the hair removal device 10.

[0046] Optionally, the light-transmitting crystal 20 is made of sapphire, whose main component is aluminum oxide. As is well known, sapphire has the advantages of high thermal conductivity and high light transmittance. Due to the high thermal conductivity of sapphire, the light-transmitting crystal 20 made of sapphire has excellent heat conduction and heat storage properties. The light-transmitting crystal 20 is cooled by the cooling plate 106. The light-transmitting crystal 20 made of sapphire can effectively apply ice to the user's skin by utilizing its excellent heat conduction and heat storage properties, thereby relieving the pain and burning sensation of the user's skin during hair removal. The user's experience when using the hair removal device 10 for hair removal is thus optimized.

[0047] Please refer to the following: Figure 4 and Figure 5 The heating component 18 includes a lamp tube 181 and a reflector cup 182, with the lamp tube 181 placed in the reflector cup 182; the heat sink 104 is connected to the reflector cup 182; the cooling component 100 includes a heat pipe 101 and a heat sink assembly, the heat sink assembly including at least two spaced heat sinks 102, the heat sink assembly being sleeved on the heat pipe 101; the cooling component 100 further includes a cooling chip 106 and a thermally conductive substrate 107, the thermally conductive substrate 107 being positioned on the heat sink housing 14, the heat pipe 101 being connected to the thermally conductive substrate 107; the cooling chip 106 includes a cooling surface 1061 and a heating surface 1062, the heating surface 1062 being in close contact with the thermally conductive substrate 107, the cooling surface 1061 being connected to the light-transmitting crystal 20; the cooling chip 106 is embedded in the heat sink housing 14.

[0048] Optionally, the main body 11 of the hair removal device further includes a circuit board assembly 111, which is connected to the fan housing 13. The circuit board assembly 111 is provided with a limiting hole 1111, and the end of the fan housing 13 away from the cooling component 100 is located in the limiting hole 1111. This design further optimizes the internal structure of the hair removal device 10, saves more internal space, and helps to reduce the size of the hair removal device 10.

[0049] Specifically, the first and second air intake channels are independent of each other. The airflow passing through the first air intake channel carries away the heat from the cooling component 100 located at the first air inlet 131, thus accelerating the cooling of the cooling component 100. This allows the heat on the heat-conducting substrate 107 and the cooling plate 106 connected to the cooling component 100 to be dissipated in a timely manner, improving the cooling efficiency of the cooling plate 106. This results in a better cooling effect when the hair removal device 10 is used, enhancing the user experience. Furthermore, the external air drawn into the second air intake channel passes through the heating component 18 and carries away the heat from the heating component 18 and the heat sink 104, thus... To accelerate the cooling of the heating element 18 and the heat sink 104, it is understood that the independent first and second air inlets dissipate heat from different parts inside the hair removal device 10 through the flowing airflow. This allows the heat in each component inside the hair removal device 10 to be dissipated in a timely manner, further improving the heat dissipation performance of the hair removal device 10. This significantly improves the durability of the hair removal device 10, making it more convenient to use. Furthermore, due to the improved heat dissipation performance of the hair removal device 10, the operating temperature of the hair removal device 10 is reduced, so the user's experience will not be affected by the hair removal device 10 getting hot.

[0050] Please continue reading. Figure 4 The heat pipe 101 is connected to the cooling plate 106 via a heat-conducting substrate 107. The heat-conducting substrate 107 is made of a heat-conducting material. The heat-conducting substrate 107 transfers the heat generated by the heating surface 1062 of the cooling plate 106 to the heat pipe 101 through contact heat dissipation. The heat pipe can absorb the heat generated by the heating surface 1062 of the cooling plate 106 more promptly, thereby improving the cooling efficiency of the cooling surface 1061 of the cooling plate 106. By setting the cooling component 100 at the first air inlet 131, the heat in the heat pipe 101 and the heat sink 102 is absorbed by the air and then promptly discharged from the hair removal device 10 by the rotation of the fan 12. This improves the heat dissipation efficiency of the cooling component 100, effectively prevents the heating component 18 from overheating and affecting the normal operation of the hair removal device 10, and further enhances the stability of the hair removal device 10.

[0051] It is understandable that the arrangement of the heat sink 102 is not limited, as long as multiple heat sinks 102 are spaced apart at the first air inlet 131 to achieve the heat dissipation function.

[0052] It is understandable that the heat pipe 101 and the heat-conducting substrate 107 can be replaced with other structures, such as plates or blocks, as long as the heat dissipation of the cooling component 100 is met.

[0053] Please see Figure 4a and Figure 5a As an optional implementation, the cooling assembly 100 may include a heat-conducting plate 101a, a cooling element 106, and a heat sink assembly. The heat sink assembly includes at least two spaced-apart heat sinks 102. One end of the heat-conducting plate 101a is positioned on the heat sink housing 14, the heat sink assembly is disposed on the heat-conducting plate 101a, and the cooling element 106 is embedded in the heat sink housing 14. The cooling element 106 includes a cooling surface 1061 and a heating surface 1062. The heating surface 1062 is in close contact with the heat-conducting plate 101a, and the cooling surface 1061 is connected to the light-transmitting crystal 20. The heat-conducting plate 101a transfers the heat generated by the heating surface 1062 of the cooling element 106 to the heat sink 102 through contact heat dissipation. After the heat in the heat sink 102 is absorbed by the air, it is promptly discharged from the hair removal device 10 by the rotation of the fan 12.

[0054] Optionally, the heat-conducting plate 101a can be any one of a vapor chamber plate, a copper plate, an aluminum plate, or a copper-aluminum hybrid plate. Among them, the vapor chamber plate is a vacuum chamber heat-spreading plate, which is similar in principle to a heat pipe and can also transfer the heat generated by the heating surface 1062 of the cooling chip 106 to the heat sink 102.

[0055] Specifically, the heat-conducting plate 101a and the heat sink assembly are integrally formed, that is, the heat sink 102 can be multiple sheet-like structures opened on the heat-conducting plate 101a, and the sheet-like structures are arranged side by side to form a heat sink assembly, so that heat can be carried away by the air in contact with it.

[0056] Please continue reading. Figure 4 , Figure 5 , Figure 4a and Figure 5aIn the first embodiment of the present invention, the heat sink 104 connected to the heating component 18 is provided with a plurality of plate-shaped structures 1041. The heat generated by the heating component 18 is conducted to the heat sink 104, and heat dissipation gaps 1042 are formed between the plate-shaped structures 1041 of the heat sink 104. The heat dissipation gaps 1042 can effectively increase the contact area between the heat sink 104 and the air, so that the heat in the heat sink 104 can be efficiently absorbed by the air, thereby improving the heat dissipation performance of the heat sink 104. Similarly, the heat pipe 101 or the heat-conducting plate 101a is provided with at least two spaced heat sinks. 102 (i.e., heat sink assembly), with air gaps 1021 formed between adjacent heat sinks 102. The air gaps 1021 between heat sinks 102 also increase the contact area between the heat sink 102 and the air, so that the heat transferred to the heat sink 102 by the heat pipe 101 or the heat conduction plate 101a can be absorbed by the air in time, thereby improving the heat dissipation performance of the heat pipe 101 or the heat conduction plate 101a. This improves the heat dissipation efficiency of the heating surface 1062 of the cooling element 106, enhances the cooling effect of the cooling element 106, and strengthens the practicality of the hair removal device 10.

[0057] Please refer to the following: Figures 5-6The air guiding mechanism 134 has an air guiding groove 1341 at one end and a flat teardrop-shaped shell 1342 at the other end. The air guiding mechanism 134 has a structure that is narrow in the middle and wide at both ends. The air guiding groove 1341 includes a long groove and a neck-shaped air guiding pipe (i.e., a central converging mechanism). The two ends of the neck-shaped air guiding pipe are connected to the air guiding groove 1341 and the teardrop-shaped shell 1342, respectively. An air vent 1343 is provided at the connection between the long groove and the neck-shaped air guiding pipe. Under the suction action of the fan 12, air flows in from the air inlet 141 and passes through the heating element 18 and the heat sink 104, carrying away the heat. When the airflow passes through the heating element 18 and the heat sink 104, it will be preferentially sprayed to the bottom of the long groove when it enters the long groove. The airflow is changed by the suction force generated by the fan 12 from the vent, thereby generating a high-speed airflow that flows along the bottom of the long groove and converges at the vent. The high-speed airflow finally... The airflow converges at the vent 1343 and flows into the teardrop-shaped housing 1342 through the neck-shaped air duct, thus dissipating the heat from the heating element 18 in the air cavity 19 and achieving the function of heat dissipation. It can be understood that the high-speed airflow flowing along the bottom of the long groove effectively prolongs the contact time between the air and the heating element 18 and the heat sink 104, allowing the air sufficient time to fully absorb the heat from the heating element 18 and the heat sink 104. Furthermore, by extending the airflow path by allowing the airflow to pass through the bottom of the air duct 1341, compared with the existing technology of extending the airflow path by extending the air duct, the internal space of the hair removal device 10 is saved, which is more conducive to reducing the size of the hair removal device 10 and better arranging its design space. At the same time, the contact time between the airflow and the heating element is extended, further enhancing the heat dissipation performance of the hair removal device 10.

[0058] Please see Figures 4-7a Since the heat at the cooling component 100 is usually higher than that at the heating component 100, targeted heat dissipation is required. The cross-sectional area of ​​the first air inlet 131 on the fan housing 130 is larger than that of the second air inlet 132, so that the efficiency of the fan 12 in drawing air from the first air inlet 131 is higher than that from the second air inlet 131. This results in higher heat dissipation efficiency for the cooling component 100 located at the first air inlet 131, prioritizing air intake and heat dissipation for the cooling component 100. It can be understood that the air intake efficiency of the first air intake channel drawing air from the first air inlet 131 is higher than that of the second air intake channel drawing air from the second air inlet 132. That is, the first air intake channel is the main air intake channel, mainly used for air intake and heat dissipation of the cooling component 100 with higher heat, while the second air intake channel is the secondary air intake channel, mainly used for air intake and heat dissipation of the heating component 18. The two are different and independent of each other.

[0059] Optionally, the fan housing 130 further includes a mounting plate 135, which has at least one small hole (not shown) to define a second air inlet 132, i.e., the second air inlet 132 can be an air inlet for air intake defined by a plurality of small holes.

[0060] As a modified embodiment, the cross-sectional area of ​​the first air inlet 131 on the fan housing 130 is equal to the cross-sectional area of ​​the second air inlet 132. That is, the efficiency of the fan 12 in drawing air from the first air inlet 131 is equal to the efficiency of drawing air from the second air inlet 131, so as to simultaneously perform high-efficiency air intake and heat dissipation on the cooling component 100 and the heating component 18.

[0061] Please refer to the following: Figures 7-11 In the first embodiment of the present invention, a hair removal device 10 further includes a housing 15, and the main body 11 of the hair removal device is disposed in the housing 15. The housing 15 includes a first housing 151, a second housing 152 and an annular housing 153. The first housing 151 is snapped into a heat dissipation housing 14, and the annular housing 153 is connected to the second housing 152. An air inlet gap 16 for air intake is provided between the first housing 151 and the annular housing 153. The first housing 151 and the annular housing 153 define an air inlet cavity 17, and an air inlet hole 141 is provided in the air inlet cavity 17. The air inlet cavity 17 is connected to the air passage cavity 19 through the air inlet hole 141. The second housing 152 is provided with an air outlet hole 1521 at the air outlet 133, and the external gas drawn into the hair removal device 10 is finally discharged from the air outlet hole 1521.

[0062] Specifically, an annular air inlet gap 16 is provided between the first housing 151 and the annular housing 153 for air intake, and an air inlet hole 1522 is provided on the second housing 15 corresponding to the first air inlet 131 for air intake. The air inlet hole 1522 and the air inlet gap 16 can simultaneously allow air intake, increasing the air intake volume and improving heat dissipation performance. Air from outside the hair removal device 10 is drawn into the hair removal device 10 through the air inlet gap 16 and the air inlet hole 1522. Finally, the airflow formed by the hot air is blown out from the air outlet 133 on the fan housing 130 and discharged from the hair removal device 10 through the air outlet 1521 on the housing 15. It can be understood that the fan 12 draws outside air into the hair removal device 10 through the air inlet gap 16 and the air inlet hole 1522 by rotation. Air flows between the internal mechanisms of the hair removal device 10 and absorbs the heat from each mechanism, finally being discharged through the air outlet 1521 on the second housing 152. This achieves the function of air circulation and heat dissipation in the hair removal device 10, effectively preventing damage to the components in the hair removal device 10 due to overheating, enhancing the durability of the hair removal device 10, and making the hair removal device 10 more practical. Furthermore, the external air drawn in through the air inlet gap 16 blows along the inner wall of the first housing 151, and the continuous airflow promptly carries away the heat from the first housing 151 and the air inlet cavity 17, making the temperature of the first housing 151 tend to be stable and not overheated. This avoids the problem of discomfort caused by the user's skin coming into contact with the overheated first housing 151, effectively optimizing the user's hair removal experience.

[0063] Optionally, the second housing 152 and the annular housing 153 can be integrally formed, or they can be separated and made independent of each other.

[0064] As a modified embodiment, the outer shell 15 includes a first shell 151, a second shell 152, and an annular shell 153, which are integrally formed with each other. An air inlet hole is provided on the first shell 151 and / or the second shell 152, and the air inlet hole communicates with the air inlet cavity 17 through an air inlet hole 141. External air is sequentially drawn into the air inlet cavity 17 through the air inlet hole and the air inlet hole 141. It is understood that the position of the air inlet hole can be flexibly set according to actual needs, as long as the condition of communication between the air inlet hole and the air inlet cavity 17 is met. The main advantage of this design is its flexibility; manufacturers can adjust the position and shape of the air inlet hole according to customer needs to satisfy the aesthetic preferences of different customers.

[0065] Please refer to the following: Figure 4 and Figure 9A suction hood 108 is fitted around the outer periphery of the heat sink assembly. The suction hood 108 has a limited airflow through-hole 109 corresponding to the air inlet 1522, which connects to both the air inlet 1522 and the first air inlet 131. Furthermore, the suction hood 108 isolates the heat sink 102 from the internal space of the hair removal device 10. The limited airflow through-hole 109 passes through the suction hood 108 and includes two opposing openings, one corresponding to the air inlet 1522 and the other corresponding to the first air inlet 131. It is understood that when the fan 12 rotates and draws air, the suction hood 108 isolates the heat sink 102 from the internal space of the hair removal device 10. The internal space of the hair removal device 10 is isolated, so it only draws in ambient temperature air from outside the device and does not draw in hot air from inside the device into the suction hood 108. This improves heat dissipation efficiency and effectively avoids the problem of overheating of internal components due to the recycling of hot air. Furthermore, external air is drawn into the suction hood 108 through the opening provided by the air limiting through hole 109 corresponding to the air inlet 1522 to dissipate heat from the heat sink 102. Subsequently, the external air that has absorbed heat is drawn into the fan housing 13 through the opening provided by the air limiting through hole 109 corresponding to the first air inlet 131 to achieve heat dissipation.

[0066] Optionally, the cooling component 100 is located between the air inlet 1522 and the fan housing 13, so that when the fan 12 rotates to draw air, the heat of the cooling component 100 can be dissipated in time, that is, the air intake and heat dissipation are smoother.

[0067] Please see Figure 11a The second embodiment of the present invention provides a hair removal device 10a, which includes a shell 15a and a main body 11a for hair removal and heat dissipation. The structure and principle of the main body 11a are the same as those of the main body 11a in the first embodiment of the present invention. The main body 11a is built into the shell 15a. The shell 15a includes a first shell 151a, a second shell 152a and an annular shell 153a. The first shell 151a and the annular shell 153a are spliced ​​together, and the second shell 152a and the annular shell 153a are spliced ​​together or integrally formed. The outer periphery of the second shell 152a is provided with a function for hair removal and heat dissipation. The device includes an air inlet grille 16a for air intake and an air outlet 1521a for air outlet. The second housing 152a is also provided with an air inlet 1522a for air intake. The hair removal device 10a simultaneously intakes air through the air inlet 1522a and the air inlet grille 16a to dissipate heat from the heating mechanism in the main body 11a, thereby improving the air intake efficiency of the main body 11a. Subsequently, the main body 11a exhausts the hot air from the air outlet 1521a to the outer shell 15a to achieve rapid heat dissipation. Furthermore, the outer shell 15a of the hair removal device 10a has an L-shaped crank structure, which is compact and easy for users to hold.

[0068] Please see Figure 11bThe third embodiment of the present invention provides a hair removal device 10b, which includes a shell 15b and a main body 11b for hair removal and heat dissipation. The structure and principle of the main body 11b are the same as those of the main body 11 in the first embodiment of the present invention. The main body 11b is built into the shell 15b. The shell 15b includes a first shell 151b, a second shell 152b, and a third shell 153b. The first shell 151b and the third shell 153b are spliced ​​together, and the second shell 152b and the third shell 153b are spliced ​​together. Alternatively, it can be integrally formed; the outer periphery of the second housing 152b is provided with an air inlet 1522b for air intake and an air outlet 1521b for air exhaust, and the periphery of the first housing 151b is provided with an air inlet 16b for air intake; the hair removal device 10b simultaneously intakes air through the air inlet 1522b and the air inlet 16b to dissipate heat from the heating mechanism in the hair removal device body 11b, thereby improving the air intake efficiency of the hair removal device body 11b. Subsequently, the hair removal device body 11b exhausts the hot air from the air outlet 1521b to the outer shell 15b, thereby achieving the purpose of rapid heat dissipation.

[0069] Please refer to the following: Figures 12-14aThe fourth embodiment of the present invention provides a fan assembly c, which includes a fan housing 13c and a fan 12c. The fan housing 13c includes a fan outer shell 130c, and the fan 12c includes a first fan blade 122c, a second fan blade 123c, and a motor 121c. A first air inlet 131c is provided on one side of the fan outer shell 130c, and a second air inlet 132c is provided on the opposite side of the first air inlet 131c. A first air outlet 133c and a second air outlet 134c are provided on the outer periphery of the fan outer shell 130c. The fan outer shell 130c is provided with an isolation plate mechanism 135c. The first fan blade 122c and the second fan blade 123c are respectively disposed on opposite sides of the isolation plate mechanism 135c. One end of the motor 121c is connected to the first fan blade 122c, and the other end is connected to the second fan blade 123c. The first air inlet 131c and the baffle plate mechanism 135c define a first air cavity 136c, and the second air inlet 132c and the baffle plate mechanism 135c define a second air cavity 137c; the first fan blade 122c is disposed in the first air cavity 136c, and the second fan blade 123c is disposed in the second air cavity 137c; it can be understood that the first air cavity 136c and the second air cavity 137c are independent of each other, so that the rotation of the first fan blade 122c and the second fan blade 123c does not affect each other, thus improving the suction efficiency; the first air outlet 133... The first air chamber 136c is correspondingly arranged with the second air outlet 134c, and the second air outlet 137c is correspondingly arranged with the second air chamber 137c. The isolation plate mechanism 135c is provided with a motor mounting slot 1351c, and the motor 121c is located in the motor mounting slot 1351c. This structure saves the installation space of the motor 121c, making the size of the fan assembly c smaller and saving the space occupied by the main body 11 of the hair removal device. The motor 121c includes a rotating shaft 1211c, one end of which is connected to the first fan blade 122c, and the other end is connected to the second fan blade 123. c connection; the first fan blade 122c includes several first blades 1221c, which are spirally distributed around the axis 1211c; the second fan blade 123c includes several second blades 1231c, which are spirally distributed around the axis 1211c and face opposite directions to the first blades 1221c. When the axis 1211c of the motor 121c rotates, the first fan blade 122c and the second fan blade 123c rotate simultaneously in the same direction. The first blade 1221c and the second blade 1231c of the second fan blade 123c face opposite directions, so that the first fan blade 122c and the second fan blade 123c can simultaneously draw air when they rotate in the same direction. It can be understood that by setting the first fan blade 122c and the second fan blade 123c relatively and facing opposite directions, the fan assembly c can achieve bidirectional air intake through one motor 121c and two fan blades. Compared with the traditional fan solution of achieving bidirectional air intake by two motors and two fan blades, the structure is simpler and the manufacturing cost is reduced.It should be noted that the fan assembly c in this embodiment is also applicable to the hair removal device body 11 in other embodiments of the present invention.

[0070] It is understood that, in conjunction with the relevant content in other embodiments of the present invention, when the fan assembly c is applied to the main body 11 of the hair removal device, the cooling assembly 100 is placed at the first air inlet 131c, and air circulates between the heating assembly 18 and the second air inlet 132c, so that the fan assembly c can simultaneously draw in air to cool the heating assembly 18 and the cooling assembly 100; furthermore, external air passing through the cooling assembly 100 is drawn into the fan housing 130c from the first air inlet 131c and discharged from the first air outlet 133c, and external air passing through the heating assembly 18 is drawn into the fan housing 130c from the second air inlet 132c and discharged from the second air outlet 134c, so as to achieve the purpose of discharging hot air, and since the first air chamber 136c and the second air chamber 137c are independent of each other, the first The air outlets 133c and 134c are more efficient, preventing turbulence from affecting airflow efficiency caused by simultaneous air intake from the first air inlet 131c and 132c. Furthermore, ambient air from outside is drawn into the first air chamber 136c from the first air inlet 131c after passing through the cooling component 100, thus absorbing and dissipating heat from the cooling component 100 located at the first air inlet 131c. The air inlet 141 on the heat sink housing 14, the air guide mechanism 134, and the second air inlet 132c on the fan housing 130c are sequentially connected, making the air intake of the second air intake channel smoother. Moreover, ambient air from outside is drawn into the second air chamber 137c from the second air inlet 132c after passing through the heating component 18, thus absorbing and dissipating heat from the heating component 18 in the air chamber 19.

[0071] Optionally, the motor 121c is a brushless DC motor with dual bearings. Two bearings (not shown) are mounted on the shaft 1211c of the motor 121c. One bearing is located near the first fan blade 122c, and the other bearing is located near the second fan blade 123c.

[0072] Compared with the prior art, the hair removal device provided by the present invention has the following beneficial effects: (1) The hair removal device provided by the present invention includes two independent air inlet channels. The first air inlet and the second air inlet on the fan housing are connected in sequence, so that the air intake of the first air inlet channel is smoother, so as to draw air and dissipate heat from the cooling component located at the first air inlet. The heat dissipation housing is provided with at least one air inlet hole, and the air inlet hole, the air guide mechanism, and the second air inlet on the fan housing are connected in sequence, so that the air intake of the second air inlet channel is smoother, so as to draw air and dissipate heat from the heating component in the air passage. It can be understood that two independent air inlet channels are constructed by opening two independent air inlets on the fan housing to achieve Simultaneously, air is drawn in to dissipate heat from both the cooling and heating components, solving the problem of simultaneously cooling multiple heating elements. This enhances the heat dissipation performance of the hair removal device, improving its durability and safety. The fan inside the casing rotates, creating a rapid airflow. This airflow enters through the first and second air inlet channels, significantly increasing the air volume entering the device's internal structure per unit time. This powerful and sufficient airflow effectively removes heat from the heating and cooling components, and dissipates it through openings in the second housing of the device. The air outlet further improves the heat dissipation performance of the hair removal device. Furthermore, the first and second air inlets are independent of each other. The airflow through the first air inlet carries away the heat from the cooling component located at the first air inlet, accelerating its cooling process. This allows the heat from the heat-conducting substrate and cooling plate connected to the cooling component to be dissipated in a timely manner, improving the cooling efficiency of the cooling plate and resulting in a better cooling effect during use, thus enhancing the user experience. Additionally, the outside air drawn into the second air inlet passes through the heating component and heats the heating component and heat sink. The heat is carried away, which accelerates the cooling of the heating components and heat dissipation parts. It can be understood that the independent first and second air inlets dissipate heat to different parts inside the hair removal device through the airflow. This ensures that the heat in each component inside the hair removal device can be dissipated in a timely manner, further improving the heat dissipation performance of the hair removal device. This greatly improves the durability of the hair removal device and makes it more convenient to use. Furthermore, due to the improved heat dissipation performance, the operating temperature of the hair removal device is reduced, so users will not experience the effects of the hair removal device getting hot.

[0073] (2) In the hair removal device provided by the present invention, the air guide mechanism has an air guide groove at one end and a flat teardrop-shaped shell at the other end. The air guide mechanism is a structure that is narrow in the middle and wide at both ends. The air guide groove includes a long groove and a neck-shaped air guide tube (i.e., a central gathering mechanism). The two ends of the neck-shaped air guide tube are respectively connected to the air guide groove and the teardrop-shaped shell. An air vent is provided at the connection between the long groove and the neck-shaped air guide tube. Under the suction action of the fan rotation, air flows in from the air inlet and passes through the heating element and the heat sink, carrying away the heat. When the airflow passes through the heating element and the heat sink, it will be preferentially sprayed to the bottom of the long groove when it enters the long groove. The airflow is changed by the suction force generated by the fan rotation from the vent, thereby generating a high-speed airflow that flows along the bottom of the long groove and converges at the vent. The high-speed airflow finally converges at the vent. The airflow converges at the vent and flows into the teardrop-shaped housing through the neck-shaped air duct, thus dissipating the heat from the heating element in the air cavity and achieving heat dissipation. It can be understood that the high-speed airflow flowing along the bottom of the long slot effectively extends the contact time between the air and the heating element and heat sink, allowing sufficient time for the air to fully absorb the heat. Furthermore, by extending the airflow path through the bottom of the air duct, this technique saves internal space compared to existing methods that extend the airflow path by extending the duct. It also allows for a smaller device size and better design space arrangement, while extending the contact time between the airflow and the heating element further enhances the heat dissipation performance of the device.

[0074] (3) In the hair removal device provided by the present invention, the heat pipe is connected to the cooling plate through a heat-conducting substrate. The heat-conducting substrate is made of a heat-conducting material. The heat-conducting substrate transfers the heat generated by the heating surface of the cooling plate to the heat pipe through contact heat dissipation. The heat pipe can absorb the heat generated by the heating surface of the cooling plate more promptly, thereby improving the cooling efficiency of the cooling surface of the cooling plate. By setting the cooling component at the first air inlet, the heat in the heat pipe and heat sink is absorbed by the air and then discharged from the hair removal device in a timely manner by the fan rotation. This improves the heat dissipation efficiency of the cooling component and effectively avoids the heating component from affecting the normal operation of the hair removal device due to overheating, further improving the stability of the hair removal device.

[0075] (4) In the hair removal device provided by the present invention, the heat dissipation component corresponding to the heating component is provided with multiple sheet-like mechanisms. The heat generated by the heating component is conducted to the heat dissipation component, and heat dissipation gaps are formed between the sheet-like mechanisms of the heat dissipation component. The heat dissipation gaps can effectively increase the contact area between the heat dissipation component and the air, so that the heat in the heat dissipation component can be efficiently absorbed by the air, thereby improving the heat dissipation performance of the heat dissipation component. Similarly, the heat dissipation fin assembly sleeved on the heat pipe includes at least two heat dissipation fins arranged at intervals. An air passage gap is formed between adjacent heat dissipation fins. The air passage gap between the heat dissipation fins also plays the role of increasing the contact area between the heat dissipation fins and the air, so that the heat transferred from the heat pipe to the heat dissipation fin assembly can be absorbed by the air in time, thereby improving the heat dissipation performance of the heat pipe. This improves the heat dissipation efficiency of the heating surface of the cooling plate, enhances the cooling effect of the cooling plate, and enhances the practicality of the hair removal device.

[0076] (5) In the hair removal device provided by the present invention, an annular air inlet gap is provided between the first housing and the annular housing for air intake, and an air inlet hole is provided at the second housing corresponding to the first air inlet for air intake. The air inlet hole and the air inlet gap can simultaneously allow air intake, increasing the air intake volume and improving the heat dissipation performance. Air from outside the hair removal device is drawn into the hair removal device through the air inlet gap and the air inlet hole, and finally the airflow formed by the hot air is blown out from the air outlet on the fan housing and discharged outside the hair removal device through the air outlet on the housing. It can be understood that by rotating the fan, external air is drawn into the hair removal device through the air inlet gap and the air inlet hole, and the drawn air is heated by the air in the hair removal device. The internal components circulate and absorb heat from each other, which is then exhausted through the air outlet on the second shell. This achieves the function of air circulation and heat dissipation in the hair removal device, effectively preventing damage to the components due to overheating, enhancing the device's durability, and making it more practical. Furthermore, external air drawn in through the air inlet gap blows along the inner wall of the first shell, and the continuous airflow promptly carries away the heat from the first shell and the air inlet cavity, keeping the temperature of the first shell stable and preventing overheating. This avoids discomfort caused by the user's skin coming into contact with an overheated first shell, effectively optimizing the user's hair removal experience.

[0077] (6) In the hair removal device provided by the present invention, the light-transmitting crystal is made of sapphire. Sapphire has the advantages of high thermal conductivity and high light transmittance. Due to the high thermal conductivity of sapphire, the light-transmitting crystal made of sapphire has excellent heat conduction and heat storage properties. The light-transmitting crystal is cooled by a cooling plate. The light-transmitting crystal made of sapphire can effectively apply ice to the user's skin by utilizing its excellent heat conduction and heat storage properties, thereby relieving the pain and burning sensation of the user's skin during hair removal. The user's experience when removing hair through the hair removal device is thus optimized.

[0078] (7) In the hair removal device provided by the present invention, the position of the air inlet hole on the outer shell for drawing in external air can be flexibly set according to actual needs. It is only necessary to meet the condition that the air inlet hole is connected to the air inlet cavity. The main advantage of this design is its flexibility. Manufacturers can adjust the position and shape of the air inlet hole according to the needs of customers to meet the aesthetics of different customers.

[0079] (8) In the hair removal device of the present invention, the stability of the light-emitting head assembly of the hair removal device is effectively enhanced by stacking and pressing the light-transmitting crystal, the light-filtering lens, the light-shielding sheet, the heating element and the heat dissipation element in the heat dissipation shell in sequence. This avoids the hair removal device from malfunctioning due to the loosening of internal parts during use, thus improving the safety of the hair removal device. Furthermore, by setting a silicone sealing ring between the light-transmitting crystal and the light-filtering lens for sealing, the light-transmitting crystal, the silicone sealing ring and the light-filtering lens form a sealed cavity. During the pressing and installation process, the air in the sealed cavity is squeezed out, creating a vacuum between the light-transmitting crystal and the light-filtering lens. This avoids the problem of air between the light-filtering lens and the light-transmitting crystal condensing into water droplets upon cooling, which could lead to electric shock to the human body, further improving the safety performance of the hair removal device.

[0080] (9) The hair removal device provided by the present invention uses a suction method to dissipate heat from the heating and cooling components. Under the action of the fan rotation, the ambient temperature air first passes through the heating and cooling components to remove the heat from them. Then, the air that has absorbed the heat is drawn into the fan housing and finally discharged from the outer shell of the hair removal device by the fan. Traditional blower cooling uses the fan rotation to blow air to form a high-speed airflow, which is used to blow high-heat components to achieve the purpose of heat dissipation. However, while the high-speed airflow removes the heat from the high-heat components, it also forms a high-temperature airflow. If the high-temperature airflow blows on a certain local area inside the hair removal device for a long time, it will cause the temperature of that area to rise sharply and eventually cause the components in that area to overheat and be damaged. The suction cooling method used in the present invention uses a fan to blow air to remove heat from the components. The device directly draws the hot airflow past the high-heat components (i.e., the heating and cooling components) into the fan housing, preventing the hot airflow from lingering excessively within the internal structure of the hair removal device. Furthermore, the unique structure of the fan housing causes the hot airflow flowing through the second air inlet channel to converge in the air guide mechanism (i.e., the air guide mechanism restricts the hot airflow). Since there are no critical or easily damaged components near the air guide mechanism, even if the temperature of the air guide mechanism rises, it will not damage nearby components. It is understood that, compared to traditional blower-based heat dissipation methods, this invention's fan-assisted heat dissipation method avoids the problem of heat concentration leading to excessively high local temperatures and damage to components in the hair removal device, further improving the durability and safety of the device.

[0081] (10) When the fan assembly is used in the main body of the hair removal device, the cooling assembly is placed at the first air inlet, and the air circulates between the heating assembly and the second air inlet. The fan assembly a can then simultaneously draw in air to cool the heating assembly and the cooling assembly. Furthermore, external air passing through the cooling assembly is drawn into the fan housing through the first air inlet and discharged through the first air outlet. Similarly, external air passing through the heating assembly is drawn into the fan housing through the second air inlet and discharged through the second air outlet, thus achieving the purpose of discharging hot air. Moreover, since the first and second air chambers are independent of each other, the air output from the first and second air outlets is more efficient. To ensure smooth airflow and prevent turbulence from affecting air output efficiency due to simultaneous air intake from the first and second air inlets; furthermore, ambient temperature air from outside is drawn into the first air cavity through the first air inlet after passing through the cooling components, thereby absorbing and dissipating heat from the cooling components located at the first air inlet; the air inlet holes on the heat dissipation housing, the air guide mechanism, and the second air inlet on the fan housing are sequentially connected, making the air intake of the second air intake channel smoother, and ambient temperature air from outside is drawn into the second air cavity through the second air inlet after passing through the heating components, thereby absorbing and dissipating heat from the heating components in the air cavity, achieving the purpose of bidirectional air intake and heat dissipation.

[0082] (11) The first air chamber and the second air chamber are independent of each other, so that the rotation of the first fan blade and the second fan blade does not affect each other, thus improving the suction efficiency; the isolation plate mechanism is provided with a motor mounting slot, and the motor is located in the motor mounting slot. This structure saves the installation space of the motor, making the fan assembly smaller and saving the space occupied by the main body of the hair removal device; the second fan blade includes several second blades, which are spirally distributed around the axis of rotation and opposite to the orientation of the first blade. When the motor axis rotates, the first fan blade and the second fan blade rotate in the same direction at the same time. Since the first blade of the first fan blade and the second blade of the second fan blade are opposite in orientation, the first fan blade and the second fan blade can also suction air at the same time when they are rotating in the same direction; it can be understood that by setting the first fan blade and the second fan blade with opposite blade orientation, the fan assembly can achieve bidirectional suction air through one motor and two fan blades. Compared with the traditional fan assembly structure that achieves bidirectional suction air through two motors and two fan blades, it is simpler and reduces the manufacturing cost.
