Technical Field

[0003] In existing technologies, hair removal devices are usually equipped with heat dissipation devices. The heat dissipation performance of the heat dissipation device directly affects the cooling effect and durability of the hair removal device.

[0018] Compared with the prior art, the hair removal device provided by this utility model has the following advantages: 1. The hair removal device of this utility model includes a light-emitting device, which includes a light source mechanism. The light source mechanism includes a light source support, a light-emitting element, and a light-transmitting element. A light-emitting cavity and a light-transmitting cavity are formed within the light source support. The light-emitting element and the light-transmitting element are respectively disposed within the light-emitting cavity and the light-transmitting cavity, and the light generated by the light-emitting element is transmitted through the light-transmitting element. The light source mechanism also includes a cooling plate disposed on at least one side of the light-transmitting element; a liquid cooling mechanism, which includes a liquid cooling block disposed on the side of the cooling plate away from the light-transmitting element. A liquid cooling channel is formed within the liquid cooling block, and an inlet pipe and an outlet pipe are respectively connected to both ends of the liquid cooling channel; and an air cooling mechanism, which includes an air duct and a fan. The fan is connected to the light-emitting cavity through the air duct to draw air or blow air to dissipate heat from the light-emitting cavity. The new hair removal device uses a fan to remove heat generated by the light-emitting component through air cooling, and water cooling to further reduce the temperature of the light-transmitting component, thus enhancing the cooling effect. This combination of water and air cooling effectively dissipates heat from the light source mechanism, while simultaneously enhancing the cooling effect. Furthermore, the two cooling systems operate independently; even if one system malfunctions, the other will still ensure the device's continued operation, significantly improving its durability. The improved heat dissipation also lowers the device's operating temperature, preventing overheating and ensuring a better user experience.

[0019] 2. The hair removal device provided in this embodiment of the present invention also includes a water pumping device, which is provided with a water supply pipe and a water return pipe. The water supply pipe is connected to the water inlet pipe, and the water return pipe is connected to the water outlet pipe. The water pumping device circulates and pumps the coolant into the hair removal device for heat dissipation.

[0020] 3. The pumping device of the hair removal device provided in this embodiment of the present invention also includes a coolant. The coolant flows out of the pumping device and flows sequentially through the water supply pipe, the water inlet pipe, and the liquid cooling channel to dissipate heat and cool the light-transmitting component. Then it flows out of the liquid cooling channel and flows sequentially through the water outlet pipe and the water return pipe, and is finally recycled back into the pumping device. The coolant with a lower temperature flowing out of the pumping device flows through the liquid cooling channel. The heat of the light-transmitting component is conducted to the liquid cooling block by the cooling plate. This heat is finally carried away by the coolant flowing through the liquid cooling channel, so that the heat of the light-transmitting component can be dissipated in time. After the heat dissipation is completed, the coolant with an increased temperature is recycled back into the pumping device for cooling, so as to realize the cyclic cooling of the light-transmitting component.

[0021] 4. The flow rate of the coolant in the hair removal device provided in this embodiment of the utility model is 0.2-0.6L / min. By setting the flow rate of the coolant in the range of 0.2-0.6L / min, the coolant has a sufficient circulation speed, which improves the heat exchange efficiency and removes the heat of the hair removal device in time.

[0022] 5. The hair removal device of this utility model has two cooling plates arranged on opposite sides of the light-transmitting component, and the liquid cooling mechanism includes two liquid cooling blocks respectively arranged corresponding to the two cooling plates; the cooling plate includes a cooling surface and a heat dissipation surface, the cooling surface is in contact with the light-transmitting component, and the heat dissipation surface is in contact with the liquid cooling block; the cooling plates are arranged on opposite sides to ensure that the heat dissipation effect of the light-transmitting component is uniform and that no part of it will overheat, making the hair removal experience more comfortable for the user.

[0023] 6. The liquid cooling channel of the hair removal device of this utility model is in the shape of a continuous S-shaped bend; the purpose of adopting the continuous S-shaped bend structure is to extend the distance of the liquid cooling channel, so that the coolant flowing through the liquid cooling channel can carry away more heat and improve the heat dissipation performance.

[0024] 7. The water outlet pipe of the hair removal device of this utility model includes a main water outlet pipe and two symmetrically arranged sub-water outlet pipes. One end of each of the two sub-water outlet pipes is connected to the main water outlet pipe, and the other end is connected to the liquid cooling channel of each of the two liquid cooling blocks. The water inlet pipe includes a main water inlet pipe and two symmetrically arranged sub-water inlet pipes. One end of each of the two sub-water inlet pipes is connected to the main water inlet pipe, and the other end is connected to the liquid cooling channel of each of the two liquid cooling blocks. This arrangement is to ensure that the flow rate of the coolant flowing through both sides of the light-transmitting element is the same, so that the temperature distribution of the light-transmitting element is as uniform as possible, and the user's hair removal experience is more comfortable.

[0025] 8. The light source mechanism of the hair removal device of this utility model also includes a filter element, which is disposed between the light-emitting element and the light-transmitting element; the filter element is used to filter harmful spectra, retain harmless spectra, and reduce the emission of harmful ultraviolet rays and other light.

[0026] 9. The hair removal device of this utility model has a gap between the filter element and the light-transmitting element; the light-transmitting element is wrapped with a padding layer, the padding layer including a sealing part located near the end of the filter element, the sealing part sealing the gap; so that the light-transmitting element, the sealing part and the filter element 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 element and the filter element, avoiding the problem of air between the filter element and the light-transmitting element condensing into water droplets when it cools down, which could lead to electric shock to the human body, and further improving the safety performance of the hair removal device.

[0027] 10. The hair removal device of this utility model has a guide shell at one end where the air duct connects to the light-emitting cavity; the length of the guide shell is greater than the length of the light-emitting element; the greater length of the guide shell can maximize the heat generated by the light-emitting element to be guided into the air duct through the guide shell, or the cold air blown out by the fan can be quickly diffused to both sides of the light-emitting element by the structure of the guide shell, so that the hot air generated by the light-emitting element can be concentrated and drawn away or blown away, and the hot air will not stay inside the hair removal device for too long, thus improving the heat dissipation effect.

[0028] 11. The hair removal device of this utility model has two air inlets on opposite sides of the light-emitting cavity, which define the airflow shell and the light-emitting cavity. The fan can also draw in external cold air through the air inlets. During the drawing process, the cold air can further dissipate heat from the light-emitting component. Alternatively, when the fan blows air, it can expel hot air from the air inlets more quickly, thereby improving the heat dissipation effect of the hair removal device.

[0029] 12. The light source mechanism of the hair removal device of this utility model also includes a reflector cup and a heat sink. The reflector cup and the heat sink are arranged in the light-emitting cavity and are arranged sequentially along the side of the light-emitting element away from the light-transmitting element. The reflector cup is attached to the heat sink. The reflector cup can concentrate the emitted light and emit it through the light-transmitting element, thereby improving the hair removal effect. At the same time, the heat sink is attached to the reflector cup to conduct the heat emitted by the light-emitting element.

[0030] 13. The heat dissipation component of the hair removal device of this utility model includes a bonding part and at least two strip-shaped grid-like heat dissipation mechanisms. Each strip-shaped grid-like heat dissipation mechanism is composed of several spaced sheet-like mechanisms. The sheet-like mechanisms define an air passage gap between each pair of sheet-like mechanisms, and the air inlet is positioned opposite to the air passage gap. The sheet-like mechanisms on the strip-shaped grid-like heat dissipation mechanism can disperse heat, making heat dissipation more sufficient. At the same time, the air inlet and the air passage gap are aligned, so that when the fan is working, the cold air drawn in through the air inlet or blown out by the fan can pass through the sheet-like mechanisms and carry away more heat during the air intake or blowing process, thereby improving the heat dissipation effect of the hair removal device.

[0045] Please combine Figure 1 , Figure 2 , Figure 4 and Figure 6The first embodiment of the present invention provides a hair removal device 1, which includes a light-emitting device 2. The light-emitting device 2 includes a light source mechanism 10, which includes a light source support 100, a light-emitting element 101, and a light-transmitting element 102. A light-emitting cavity 1000 and a light-transmitting cavity 1001 are formed in the light source support 100. The light-emitting element 101 and the light-transmitting element 102 are respectively disposed in the light-emitting cavity 1000 and the light-transmitting cavity 1001. The light generated by the light-emitting element 101 is transmitted through the light-transmitting element 102. The light source mechanism 10 also includes a cooling plate 106 disposed on at least one side of the light-transmitting element 102. The hair removal device 1 also includes a liquid cooling mechanism 11, which includes a liquid cooling block 110 disposed on the side of the cooling plate 106 away from the light-transmitting element 102. A liquid cooling channel 1100 is formed in the liquid cooling block 110, and the two ends of the liquid cooling channel 1100 are respectively connected to a water inlet pipe 111 and a water outlet pipe 112. The hair removal device 1 also includes an air cooling mechanism 12, which includes an air duct 120 and a wind duct. The fan 121 is connected to the light-emitting cavity 1000 through the air duct 120 to draw or blow air to the light-emitting cavity 1000 for heat dissipation. The hair removal device 1 provided in the first embodiment of this utility model uses the fan 121 to draw or blow away the heat generated by the light-emitting element 101 through air cooling. On the other hand, water cooling is used on the light-transmitting element 102 to further cool down the light-transmitting element 102 and improve the cooling effect. The combination of water cooling and air cooling is used to dissipate heat from the light source mechanism 10 that generates heat, while enhancing the cooling effect. The two heat dissipation devices are independent of each other. Even if one heat dissipation mechanism fails, the other heat dissipation mechanism will ensure the normal use of the hair removal device to a certain extent, which greatly improves the durability of the hair removal device. Furthermore, due to the improved heat dissipation performance of the hair removal device, the working temperature of the hair removal device is reduced, and the user will not experience the effect of the hair removal device being too hot.

[0046] Furthermore, the hair removal device 1 also includes a water pumping device 30, which is equipped with a water supply pipe 31 and a water return pipe 32. The water supply pipe 31 is connected to the water inlet pipe 111, and the water return pipe 32 is connected to the water outlet pipe 112. The water pumping device 30 pumps the coolant into the hair removal device repeatedly for heat dissipation.

[0047] Specifically, the coolant flows out from the pumping device 30 and flows sequentially through the water supply pipe 31, the inlet pipe 111, and the liquid cooling channel 1100 to cool the light-transmitting element 102. Then, it flows out from the liquid cooling channel 1100 and flows sequentially through the outlet pipe 112 and the return pipe 32, and is finally returned to the pumping device 30. The coolant with a lower temperature flowing out from the pumping device 30 flows through the liquid cooling channel 1100, and the heat of the light-transmitting element 102 is conducted to the liquid cooling block 110 by the cooling plate 106. This heat is finally carried away by the coolant flowing through the liquid cooling channel 1100, so that the heat of the light-transmitting element 102 can be dissipated in time. After the heat dissipation is completed, the coolant with an increased temperature is returned to the pumping device 30 for cooling, so as to realize the cyclic cooling of the light-transmitting element 102.

[0048] Specifically, the coolant includes liquids containing antifreeze. Since the hair removal device may face low-temperature environments when changing locations, the coolant, including liquids containing antifreeze, can prevent the coolant from freezing and stopping its flow in low-temperature environments, thus avoiding the damage to the cooling pipes of the hair removal device caused by solidification and increased volume.

[0049] Furthermore, the flow rate of the coolant is 0.2-0.6 L / min. By setting the flow rate of the coolant within the range of 0.2-0.6 L / min, the coolant has sufficient circulation speed, which improves heat exchange efficiency and removes the heat from the hair removal device in a timely manner.

[0050] As an optional implementation, the hair removal device 1 has two cooling plates 106 arranged on opposite sides of the light-transmitting element 102. The liquid cooling mechanism 11 includes two liquid cooling blocks 110 respectively arranged corresponding to the two cooling plates 106. The cooling plate 106 includes a cooling surface 1060 and a heat dissipation surface 1061 facing each other. The cooling surface 1060 contacts the light-transmitting element 102, and the heat dissipation surface 1061 contacts the liquid cooling block 110. The arrangement of the cooling plates 106 on opposite sides ensures that the heat dissipation effect of the light-transmitting element 102 is uniform and that no part of it will overheat, making the hair removal experience more comfortable for the user.

[0051] Further, please refer to Figure 4 The liquid cooling channel 1100 has an S-shaped continuous bend. The purpose of adopting the S-shaped continuous bend structure is to extend the distance of the liquid cooling channel 1100, so that the coolant flowing through the liquid cooling channel 1100 can carry away more heat and improve heat dissipation performance.

[0052] Optionally, the shape of the liquid cooling channel 1100 is not limited as long as it can meet the liquid cooling stroke required for heat dissipation.

[0053] For details, please refer to Figure 6 The water outlet pipe 112 includes a main water outlet pipe 1120 and two symmetrically arranged sub-water outlet pipes 1121. One end of each sub-water outlet pipe 1121 is connected to the main water outlet pipe 1120, and the other end is connected to the liquid cooling channel 1100 of each of the two liquid cooling blocks 110. The water inlet pipe 111 includes a main water inlet pipe 1110 and two symmetrically arranged sub-water inlet pipes 1111. One end of each sub-water inlet pipe 1111 is connected to the main water inlet pipe 1110, and the other end is connected to the liquid cooling channel 1100 of each of the two liquid cooling blocks 110. This arrangement is to ensure that the flow rate of the coolant flowing through both sides of the light-transmitting element 102 is the same, so that the temperature distribution of the light-transmitting element 102 is as uniform as possible, making the user's hair removal experience more comfortable.

[0054] Furthermore, please combine Figure 3 and Figure 5The light source mechanism 10 also includes a filter element 104, which is disposed between the light-emitting element 101 and the light-transmitting element 102. The filter element 104 is used to filter harmful spectra, retain harmless spectra, and reduce the emission of harmful ultraviolet rays and other light.

[0055] Furthermore, a gap 105 is left between the light filter 104 and the light-transmitting element 102; the light-transmitting element 102 is wrapped with a pad 103, which includes a sealing part 1030 located near the end of the light filter 104, and the sealing part 1030 seals the gap 105; thus, a sealed cavity is formed between the light-transmitting element 102, the sealing part 1030 and the light filter 104. 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 element 102 and the light filter 104. This avoids the air between the light filter 104 and the light-transmitting element 102 from condensing into water droplets that affect the light output, and also avoids the problem of condensation flowing into the circuit and burning out the circuit, or even causing electric shock to the human body, thus further improving the safety performance of the hair removal device.

[0056] For details, please refer to Figure 2 , Figure 3 and Figure 6 The fan 121 includes a housing 1210 and fan blades 1211 disposed within the housing 1210. In some specific embodiments, hot air is drawn into the fan 121 by the fan blades 1211. The air duct 120 includes an air inlet channel 1200 and a lower housing 1201. The lower housing 1201 is connected to the housing 1210 and defines an air inlet cavity 1212 within the housing 1210. One end of the air inlet channel 1200 is connected to the light-emitting cavity 1000, and the other end is connected to the lower housing 1201. In some specific embodiments, some of the heat generated by the light-emitting element 101 is drawn into the air inlet cavity 1212 through the air inlet channel 1200, while the fan blades 1211 drive airflow, which can efficiently dissipate heat.

[0057] Specifically, the lower shell 1201 is disc-shaped, and the center of the lower shell 1201 and the rotation center of the fan blade 1211 are on the same vertical line (e.g., Figure 3 As shown in the middle L), the lower shell 1201 is designed in a disc shape to correspond to the fan blade 1211, and the center of the lower shell 1201 and the rotation center of the fan blade 1211 are on the same vertical line. This maximizes the use of the wind force generated by the fan blade 1211. Heat is drawn in through the air inlet channel 1200 and directly enters the air inlet cavity 1212 through the lower shell 1201, where it is drawn away by the fan blade 1211, thus improving the heat dissipation effect of the air-cooling mechanism 12.

[0058] Specifically, the housing 1210 also has an air outlet 1213 corresponding to the fan blade 1211, so that the fan blade 1211 can expel hot air in time.

[0059] Furthermore, a guide shell 1202 is provided at one end of the air duct 120 connected to the light-emitting cavity 1000; the length of the guide shell 1202 is greater than the length of the light-emitting element 101; this design can maximize the heat generated by the light-emitting element 101 to be guided into the air duct 120 by the guide shell 1202 or the cold air blown out by the fan 121 can be rapidly diffused to both sides of the light-emitting element 101 by the structure of the guide shell 1202, so that the hot air generated by the light-emitting element 101 can be concentrated and drawn away or blown away, and the hot air will not stay inside the hair removal device for too long, thus improving the heat dissipation effect.

[0060] Furthermore, the air guide shell 1202 and the light-emitting cavity 1000 define two air inlets 1010 on opposite sides of the light-emitting cavity 1000; the fan 121 can also draw in external cold air through the air inlets 1010. During the intake process, the cold air can further dissipate heat from the light-emitting element 101, or when the fan 121 blows air, it can expel hot air from the air inlets 1010 more quickly, thereby improving the heat dissipation effect of the hair removal device 1.

[0061] Optionally, the rotation direction of the fan blades 1211 and the specific suction or blowing effect are not limited here, as long as the air-cooling mechanism 12 can expel the heat or hot air generated in the hair removal device 1 in a timely manner.

[0062] Further, please refer to Figure 2 , Figure 5 and Figure 6 The light source mechanism 10 also includes a reflector 107 and a heat sink 108. The reflector 107 and the heat sink 108 are disposed in the light-emitting cavity 1000 and are arranged sequentially along the side of the light-emitting element 101 away from the light-transmitting element 102. The reflector 107 is attached to the heat sink 108. The reflector 107 can concentrate the emitted light so that it is emitted by the light-transmitting element 102, thereby improving the hair removal effect. At the same time, the heat sink 108 is attached to the reflector 107 to conduct the heat dissipated by the light-emitting element 101.

[0063] Optionally, the light-transmitting element 102 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 element 102 made of sapphire has excellent heat conduction and heat storage properties. The light-transmitting element 102 is cooled by the cooling plate 106. The light-transmitting element 102 utilizes its excellent heat conduction and heat storage properties to effectively apply ice to the user's skin, 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 is thus optimized.

[0064] Furthermore, the heat dissipation component 108 includes a bonding portion 1080 and at least two strip-shaped grid-like heat dissipation mechanisms 1081. Each strip-shaped grid-like heat dissipation mechanism 1081 is composed of several spaced sheet-like mechanisms 1082. The sheet-like mechanisms 1082 define an air passage gap 1083 in pairs. The air inlet 1010 is directly opposite to the air passage gap 1083. The sheet-like mechanisms 1082 on the strip-shaped grid-like heat dissipation mechanism 1081 can disperse heat, making heat dissipation more sufficient. At the same time, the air inlet 1010 is directly opposite to the air passage gap 1083. When the fan is working, the cold air drawn in through the air inlet 1010 and blown out by the fan 121 passes through the sheet-like mechanisms 1082, and carries away more heat during the air intake or blowing process, thereby improving the heat dissipation effect of the hair removal device.

[0065] For details, please refer to Figure 1 and Figure 7 The outer shell 20 of the light-emitting device 2 of the hair removal device is provided to form a hair removal device handpiece 3. The outer shell 20 is also provided with heat dissipation holes 200 and an air hood 21 is provided on the outside of the air outlet 1213 of the fan 121, which further improves the heat dissipation effect of the hair removal device 1.

[0066] Compared with the prior art, the hair removal device provided by this utility model has the following advantages: 1. The hair removal device of this utility model includes a light-emitting device, which includes a light source mechanism. The light source mechanism includes a light source support, a light-emitting element, and a light-transmitting element. A light-emitting cavity and a light-transmitting cavity are formed within the light source support. The light-emitting element and the light-transmitting element are respectively disposed within the light-emitting cavity and the light-transmitting cavity, and the light generated by the light-emitting element is transmitted through the light-transmitting element. The light source mechanism also includes a cooling plate disposed on at least one side of the light-transmitting element; a liquid cooling mechanism, which includes a liquid cooling block disposed on the side of the cooling plate away from the light-transmitting element. A liquid cooling channel is formed within the liquid cooling block, and an inlet pipe and an outlet pipe are respectively connected to both ends of the liquid cooling channel; and an air cooling mechanism, which includes an air duct and a fan. The fan is connected to the light-emitting cavity through the air duct to draw air or blow air to dissipate heat from the light-emitting cavity. The new hair removal device uses a fan to remove heat generated by the light-emitting component through air cooling, and water cooling to further reduce the temperature of the light-transmitting component, thus enhancing the cooling effect. This combination of water and air cooling effectively dissipates heat from the light source mechanism, while simultaneously enhancing the cooling effect. Furthermore, the two cooling systems operate independently; even if one system malfunctions, the other will still ensure the device's continued operation, significantly improving its durability. The improved heat dissipation also lowers the device's operating temperature, preventing overheating and ensuring a better user experience.

[0067] 2. The hair removal device provided in this embodiment of the present invention also includes a water pumping device, which is provided with a water supply pipe and a water return pipe. The water supply pipe is connected to the water inlet pipe, and the water return pipe is connected to the water outlet pipe. The water pumping device circulates and pumps the coolant into the hair removal device for heat dissipation.

[0068] 3. The pumping device of the hair removal device provided in this embodiment of the present invention also includes a coolant. The coolant flows out of the pumping device and flows sequentially through the water supply pipe, the water inlet pipe, and the liquid cooling channel to dissipate heat and cool the light-transmitting component. Then it flows out of the liquid cooling channel and flows sequentially through the water outlet pipe and the water return pipe, and is finally recycled back into the pumping device. The coolant with a lower temperature flowing out of the pumping device flows through the liquid cooling channel. The heat of the light-transmitting component is conducted to the liquid cooling block by the cooling plate. This heat is finally carried away by the coolant flowing through the liquid cooling channel, so that the heat of the light-transmitting component can be dissipated in time. After the heat dissipation is completed, the coolant with an increased temperature is recycled back into the pumping device for cooling, so as to realize the cyclic cooling of the light-transmitting component.

[0069] 4. The flow rate of the coolant in the hair removal device provided in this embodiment of the utility model is 0.2-0.6L / min. By setting the flow rate of the coolant in the range of 0.2-0.6L / min, the coolant has a sufficient circulation speed, which improves the heat exchange efficiency and removes the heat of the hair removal device in time.

[0070] 5. The hair removal device of this utility model has two cooling plates arranged on opposite sides of the light-transmitting component, and the liquid cooling mechanism includes two liquid cooling blocks respectively arranged corresponding to the two cooling plates; the cooling plate includes a cooling surface and a heat dissipation surface, the cooling surface is in contact with the light-transmitting component, and the heat dissipation surface is in contact with the liquid cooling block; the cooling plates are arranged on opposite sides to ensure that the heat dissipation effect of the light-transmitting component is uniform and that no part of it will overheat, making the hair removal experience more comfortable for the user.

[0071] 6. The liquid cooling channel of the hair removal device of this utility model is in the shape of a continuous S-shaped bend; the purpose of adopting the continuous S-shaped bend structure is to extend the distance of the liquid cooling channel, so that the coolant flowing through the liquid cooling channel can carry away more heat and improve the heat dissipation performance.

[0072] 7. The water outlet pipe of the hair removal device of this utility model includes a main water outlet pipe and two symmetrically arranged sub-water outlet pipes. One end of each of the two sub-water outlet pipes is connected to the main water outlet pipe, and the other end is connected to the liquid cooling channel of each of the two liquid cooling blocks. The water inlet pipe includes a main water inlet pipe and two symmetrically arranged sub-water inlet pipes. One end of each of the two sub-water inlet pipes is connected to the main water inlet pipe, and the other end is connected to the liquid cooling channel of each of the two liquid cooling blocks. This arrangement is to ensure that the flow rate of the coolant flowing through both sides of the light-transmitting element is the same, so that the temperature distribution of the light-transmitting element is as uniform as possible, and the user's hair removal experience is more comfortable.

[0073] 8. The light source mechanism of the hair removal device of this utility model also includes a filter element, which is disposed between the light-emitting element and the light-transmitting element; the filter element is used to filter harmful spectra, retain harmless spectra, and reduce the emission of harmful ultraviolet rays and other light.

[0074] 9. The hair removal device of this utility model has a gap between the filter element and the light-transmitting element; the light-transmitting element is wrapped with a padding layer, the padding layer including a sealing part located near the end of the filter element, the sealing part sealing the gap; so that the light-transmitting element, the sealing part and the filter element 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 element and the filter element, avoiding the problem of air between the filter element and the light-transmitting element condensing into water droplets when it cools down, which could lead to electric shock to the human body, and further improving the safety performance of the hair removal device.

[0075] 10. The hair removal device of this utility model has a guide shell at one end where the air duct connects to the light-emitting cavity; the length of the guide shell is greater than the length of the light-emitting element; the greater length of the guide shell can maximize the heat generated by the light-emitting element to be guided into the air duct through the guide shell, or the cold air blown out by the fan can be quickly diffused to both sides of the light-emitting element by the structure of the guide shell, so that the heat generated by the light-emitting element can be concentrated and absorbed or blown away, and the hot air will not stay inside the hair removal device for too long, thus improving the heat dissipation effect.

[0076] 11. The hair removal device of this utility model has two air inlets on opposite sides of the light-emitting cavity, which define the airflow shell and the light-emitting cavity. The fan can also draw in external cold air through the air inlets. During the drawing process, the cold air can further dissipate heat from the light-emitting component. Alternatively, when the fan blows air, it can expel hot air from the air inlets more quickly, thereby improving the heat dissipation effect of the hair removal device.

[0077] 12. The light source mechanism of the hair removal device of this utility model also includes a reflector cup and a heat sink. The reflector cup and the heat sink are arranged in the light-emitting cavity and are arranged sequentially along the side of the light-emitting element away from the light-transmitting element. The reflector cup is attached to the heat sink. The reflector cup can concentrate the emitted light and emit it through the light-transmitting element, thereby improving the hair removal effect. At the same time, the heat sink is attached to the reflector cup to conduct the heat emitted by the light-emitting element.

[0078] 13. The heat dissipation component of the hair removal device of this utility model includes a bonding part and at least two strip-shaped grid-like heat dissipation mechanisms. Each strip-shaped grid-like heat dissipation mechanism is composed of several spaced sheet-like mechanisms. The sheet-like mechanisms define an air passage gap between each pair of sheet-like mechanisms, and the air inlet is positioned opposite to the air passage gap. The sheet-like mechanisms on the strip-shaped grid-like heat dissipation mechanism can disperse heat, making heat dissipation more sufficient. At the same time, the air inlet and the air passage gap are aligned, so that when the fan is working, the cold air drawn in through the air inlet or blown out by the fan can pass through the sheet-like mechanisms and carry away more heat during the air intake or blowing process, thereby improving the heat dissipation effect of the hair removal device.

[0079] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
