Description

[Technical Field]

[0001] This utility model relates to the technical field of beauty instruments, and in particular to a hair removal device. [Background Technology]

[0002] Hair removal devices, as a type of beauty instrument, are used to solve the problem of excessive hair growth. Generally, hair removal devices utilize the principle of selective photothermolysis, which emits high-energy light, such as lasers, directly to the skin surface to produce a photothermal effect. The light energy is converted into heat energy, thereby destroying the surrounding hair follicle tissue and achieving a permanent and safe hair removal effect.

[0003] However, the high-energy light emitted by hair removal devices can cause users to experience high temperatures and even skin damage if left unprotected. Currently, existing hair removal devices use sapphire crystals to filter the hot light into cold light and simultaneously cool the sapphire crystal to achieve temperature reduction. However, the current cooling methods are still insufficient, and users may still experience a burning sensation. [Utility Model Content]

[0018] Preferably, the hair removal device further includes a fan assembly, which includes a volute, a fan located inside the volute, and a connecting structure.

[0020] Preferably, the cooling plates and heat sinks of at least two sets of the cooling and heat dissipation components are stacked alternately in sequence.

[0021] Preferably, the insulating heat sink is a ceramic insulating heat sink.

[0022] Compared with the prior art, the hair removal device provided by this utility model has the following advantages:

[0023] 1. The hair removal device provided in this embodiment emits high-energy light through a light-emitting mechanism. This light is conducted, adjusted, and focused by a translucent crystal before being applied to the skin to achieve hair removal. A heat dissipation device is used to dissipate heat from the components within the device, ensuring operation within an appropriate temperature range, maintaining performance, and extending the device's lifespan. At least two sets of cooling and heat dissipation components have their cooling plates and heat sinks sequentially connected. The outer cooling plate can dissipate heat from the heating surface of the inner cooling plate in a timely manner, preventing excessive heat accumulation and maintaining optimal cooling. This efficiently cools the translucent crystal. The cooling effect of the cooling plate and the heat dissipation effect of the heat sink are sequentially transferred, effectively improving the heat dissipation and cooling effect on the translucent crystal and minimizing the burning sensation during hair removal.

[0024] 2. In the hair removal device provided in this embodiment of the present invention, the cooling element of a group of cooling and heat dissipation components near the light-transmitting crystal is at least partially in contact with the light-transmitting crystal, while the heat dissipation element of a group of cooling and heat dissipation components away from the light-transmitting crystal is at least partially in contact with the heat dissipation device. The contact between the light-transmitting crystal and the cooling element helps to conduct the heat generated by the light-transmitting crystal in a timely and effective manner, and then through the heat dissipation element to the heat dissipation device, ensuring that the heat can be quickly transferred from the heat dissipation element to the heat dissipation device. This can effectively reduce the temperature of the light-transmitting crystal, prevent it from overheating, thereby ensuring the performance and stability of the crystal, facilitating multi-stage heat dissipation, reducing the accumulation of heat inside the system, and further enhancing the heat dissipation capacity.

[0025] 3. The hair removal device provided in this embodiment of the present invention further includes a first cooling plate, a first heat sink, a second cooling plate, and a second heat sink stacked sequentially. The first cooling plate is at least partially in contact with the light-transmitting crystal, and the second heat sink is at least partially in contact with the heat dissipation device. The cooling surface of the first cooling plate contacts the light-transmitting crystal for cooling, and the first heat sink is stacked on the heating surface of the first cooling plate for heat dissipation. Sequentially, the second cooling plate is stacked on top of the first heat sink, and the cooling surface of the second cooling plate contacts the first heat sink for further cooling. The second heat sink is stacked on the heating surface of the second cooling plate and is at least partially in contact with the heat dissipation device for further heat dissipation. The sequential stacking design of the first cooling plate, the first heat sink, the second cooling plate, and the second heat sink effectively improves the heat dissipation and cooling effect on the light-transmitting crystal, minimizing the burning sensation during hair removal.

[0026] 4. The hair removal device provided in this embodiment of the present invention has a heat dissipation component that is a heat exchange plate or a heat pipe, which can provide efficient heat dissipation performance. The heat exchange plate and the heat pipe can be designed in a compact side by side, which is suitable for space-constrained scenarios, and is especially suitable for small and handheld hair removal devices.

[0027] 5. In the hair removal device provided in this embodiment, the cooling surfaces of the cooling plates of multiple cooling and heat dissipation components are all arranged facing the light-transmitting crystal, and the area of ​​the cooling surface of the cooling plate increases sequentially along the direction away from the light-transmitting crystal. This prevents the heating surface of the cooling plate close to the light-transmitting crystal from accumulating too much heat, because the cooling surface of the subsequent cooling plate dissipates the heat in time. The cooling surface of the cooling plate will not be unable to dissipate more heat in time due to the high heat of the heating surface, thus affecting the efficiency of the cooling surface.

[0028] 6. The hair removal device provided in this embodiment of the present invention includes a light-emitting mechanism comprising a lamp tube and a reflector cup disposed on the side of the lamp tube away from the light-transmitting crystal. An insulating heat sink is disposed between the reflector cup and the heat dissipation device. The reflector cup focuses the light, making the light more concentrated on the light-transmitting crystal. Therefore, a large amount of heat will accumulate on the reflector cup. The insulating heat sink disposed between the reflector cup and the heat dissipation device can effectively dissipate heat from the reflector cup. When the lamp tube generates heat, the insulating heat sink can effectively absorb and conduct this heat, helping the heat dissipation device to dissipate heat more effectively and maintain the appropriate temperature of the light-emitting mechanism, thereby improving the stability and reliability of the device. At the same time, the insulating heat sink also plays an insulating role, preventing short circuits between internal components of the hair removal device.

[0029] 7. In the hair removal device provided in this embodiment of the utility model, the insulating heat sink is attached to the reflector cup, or the insulating heat sink is attached to the heat dissipation device. The insulating heat sink attached to the reflector cup not only provides heat dissipation and insulation but also serves to fix the light tube and reflector cup, preventing them from shaking and thus improving the light emission effect. The insulating heat sink attached to the heat dissipation device effectively increases the heat dissipation area, further improving heat dissipation efficiency and insulation effect.

[0030] 8. In the hair removal device provided in this embodiment of the present invention, a filter is also provided between the light-transmitting crystal and the light-emitting mechanism. The filter has the function of filtering and can selectively transmit light of a specific wavelength to ensure that only light of the appropriate wavelength can reach the skin surface, thereby reducing adverse effects on the skin.

[0031] 9. The hair removal device provided in this embodiment of the present invention includes a light-incident crystal comprising a light-incident surface facing the light-emitting mechanism, a light-emitting surface away from the light-emitting mechanism, and four side surfaces connecting the light-incident and light-emitting surfaces, all four side surfaces being covered with a silicone encapsulation layer. When users typically perform hair removal, they apply gel to their skin; the silicone encapsulation layer acts as a local seal, preventing gel leakage into the hair removal device and causing malfunctions. Furthermore, the silicone encapsulation layer has a low thermal conductivity, and the large area of ​​the light-incident crystal covered by the silicone encapsulation layer can reduce the cooling capacity loss of the cooling element, thus enhancing its cooling effect. In addition, the silicone encapsulation layer can effectively prevent the formation of condensation in the gaps between the light-incident crystal and other components after assembly, effectively protecting the sensing elements inside the hair removal device.

[0032] 10. The hair removal device provided in this embodiment of the present invention has a first bracket outside the silicone encapsulation layer. The first bracket is used to fix the light-emitting mechanism and the light-transmitting crystal, and can also provide a heat insulation effect to prevent the heat generated by the light-emitting mechanism from being directly transferred to the surrounding shell and the light-transmitting crystal, so as to keep the working temperature of the hair removal device within an appropriate range and prevent the shell from burning the user.

[0033] 11. In the hair removal device provided in this embodiment of the present invention, the silicone encapsulation layer and the first support have a first opening, and the cooling element near the light-transmitting crystal at least partially passes through the first opening and contacts the light-transmitting crystal. This design allows the cooling element to directly contact the light-transmitting crystal through the first opening, resulting in a better cooling effect.

[0034] 12. The hair removal device provided in this embodiment of the present invention also includes a second bracket. The second bracket has a second opening. The heat dissipation component near the outer shell 10 is in direct contact with the heat dissipation device at the second opening, thereby achieving a better heat dissipation effect.

[0035] 13. In the hair removal device provided in this embodiment of the present invention, the second bracket is hollowly arranged to form a first cavity and a second cavity, the first cavity and the second cavity are connected, the light-emitting mechanism is disposed in the first cavity, and the heat dissipation device is disposed in the second cavity. The second bracket is used to fix the light-emitting mechanism and the heat dissipation device relatively, ensuring that each component is properly arranged in a compact space, does not interfere with each other during operation, and plays a role in anti-collision protection. At the same time, it can isolate dust and impurities in the external environment to a certain extent, maintaining the cleanliness of the inside of the hair removal device.

[0036] 14. The hair removal device provided in this embodiment of the present invention further includes a fan assembly. The fan assembly includes a volute, a fan located within the volute, and a connecting structure. An air distribution plate is provided within the connecting structure, and the end of the air distribution plate facing the heat dissipation device is inclined towards the second cavity. The fan assembly can introduce fresh air and deliver it to the area of ​​the heat dissipation device within the second support. The airflow carries away the generated heat, thereby maintaining the device's operation within a suitable temperature range. The air distribution plate, inclined towards the second cavity at the end facing the heat dissipation device, guides the airflow in a specific direction, preventing overheating in localized areas of the device and ensuring effective contact between air and the surface of the heat dissipation device, thus improving heat transfer efficiency. The fan assembly helps reduce the internal temperature of the device while alleviating the burden on the heat dissipation device. Working in conjunction with the heat dissipation device and other components, it maximizes the performance and stability of the hair removal device.

[0037] 15. In the hair removal device provided in this embodiment of the present invention, the air distribution plate separates the connecting structure into a first air duct facing the first cavity and a second air duct facing the second cavity. This design allows the fan assembly to dissipate heat from both the light-emitting mechanism in the first cavity and the heat dissipation device in the second cavity, thereby achieving more efficient thermal management.

[0038] 16. In the hair removal device provided in this embodiment of the present invention, at least two sets of cooling and heat dissipation components, consisting of cooling plates and heat sinks, are stacked alternately in sequence. This design ensures that each cooling plate has a corresponding heat sink for timely heat dissipation, further improving the heat dissipation effect.

[0039] 17. The hair removal device provided in this embodiment of the present invention uses a ceramic insulating heat sink. Ceramic insulating heat sinks have excellent thermal conductivity, effectively conducting heat and rapidly reducing temperature to prevent overheating. Furthermore, ceramic insulating heat sinks possess superior electrical insulation properties, effectively preventing short circuits and ensuring device safety. [Attached Image Description]

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0054] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0056] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0057] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0058] Please combine Figure 1 and Figure 2 The first embodiment of this utility model provides a hair removal device 1, including a shell 10 and a main body 20 disposed inside the shell 10. The main body 20 includes a light-emitting mechanism 11, a light-transmitting crystal 12 disposed on one side of the light-emitting direction of the light-emitting mechanism 11, and a heat dissipation device 13 disposed on the side of the light-emitting mechanism 11 opposite to the light-emitting direction of the light-emitting mechanism 11. The light-emitting mechanism 11 also includes at least two sets of cooling and heat dissipation components 14 stacked together. The cooling and heat dissipation components 14 include a cooling plate and a heat dissipation element. The cooling plates and heat dissipation elements of the at least two sets of cooling and heat dissipation components 14 are stacked alternately in sequence. The cooling plate of the set of cooling and heat dissipation components 14 close to the light-transmitting crystal 12 is at least partially in contact with the light-transmitting crystal 12, and the heat dissipation element of the set of cooling and heat dissipation components 14 far away from the light-transmitting crystal 12 is at least partially in contact with the heat dissipation device 13.

[0059] Understandably, the housing 10 includes a sealing cover 103 with an opening 100. One side of the light-transmitting crystal 12 is exposed in the opening 100. The sealing cover 103 is used to seal the gap between the housing 10 and the light-transmitting crystal 12, protect the optical or electronic components inside the hair removal device 1, and prevent dust, moisture or other impurities from entering the device. The opening 100 exposes part of the light-transmitting crystal 12 to ensure that the light emitted from the light-emitting mechanism 11 is transmitted to the outside without being obstructed by the sealing cover 103.

[0060] Understandably, the light-emitting mechanism 11 emits high-energy light, which is conducted, regulated, and focused by the light-transmitting crystal 12 before being applied to the skin to achieve hair removal. The heat dissipation device 13 is used to dissipate heat from the components inside the hair removal device 1, ensuring that the device operates within an appropriate temperature range, maintaining the performance of the hair removal device 1, and extending the device's lifespan.

[0061] Understandably, the cooling plates and heat sinks of at least two sets of cooling and heat dissipation components 14 are stacked alternately in sequence, with the cooling plates of the set of cooling and heat dissipation components 14 closest to the light-transmitting crystal 12 at least partially in contact with the light-transmitting crystal 12, and the heat sinks of the set of cooling and heat dissipation components 14 furthest from the light-transmitting crystal 12 at least partially in contact with the heat dissipation device 13. The outer cooling plate can dissipate heat from the heating surface of the inner cooling plate in a timely manner, so that the inner cooling plate is not affected by excessive heat accumulation and always maintains the optimal cooling state, which can efficiently cool the light-transmitting crystal 12. The cooling effect of the cooling plate and the heat dissipation effect of the heat sink are transferred in sequence and finally come into contact with the heat dissipation device, which can effectively improve the heat dissipation and cooling effect on the light-transmitting crystal 12 and minimize the burning sensation during hair removal.

[0062] For further information, please refer to [link / reference]. Figure 2 The main body 20 also includes a first cooling chip 140, a first heat sink 141, a second cooling chip 142, and a second heat sink 143 stacked in sequence. The first cooling chip 140 is at least partially in contact with the light-transmitting crystal 12, and the second heat sink 143 is at least partially in contact with the heat dissipation device 13.

[0063] Understandably, the cooling surface of the first cooling element 140 contacts the light-transmitting crystal 12 for cooling, and the first heat sink 141 is stacked on the heating surface of the first cooling element 140 for heat dissipation. Sequentially, the second cooling element 142 is stacked on top of the first heat sink 141, with its cooling surface contacting the first heat sink 141 for further cooling. The second heat sink 143 is stacked on the heating surface of the second cooling element 142, and at least partially contacts the heat dissipation device 13, transferring heat to the heat dissipation device 13 for further heat dissipation. This sequential stacking design of the first cooling element 140, the first heat sink 141, the second cooling element 142, and the second heat sink 143 effectively improves the heat dissipation and cooling effect on the light-transmitting crystal 12, minimizing the burning sensation during hair removal.

[0064] Furthermore, the heat sink is preferably a vapor chamber heat sink or a heat pipe heat sink.

[0065] Understandably, the first heat sink 141 and the second heat sink 143 are preferably heat sinks with a vapor chamber or heat pipes.

[0066] Understandably, vapor chamber radiators and heat pipe radiators offer efficient heat dissipation and can be designed in a compact, side-by-side configuration, making them suitable for space-constrained scenarios, especially for small, handheld hair removal devices.

[0067] Furthermore, the cooling surfaces of the cooling plates of the multiple sets of cooling and heat dissipation components 14 are all arranged facing the light-transmitting crystal 12, and the area of ​​the cooling surface of the cooling plates increases sequentially along the direction away from the light-transmitting crystal 12.

[0068] Understandably, the cooling surface area of ​​the cooling element increases sequentially along the direction away from the light-transmitting crystal 12, so that the heating surface of the cooling element close to the light-transmitting crystal 12 will not accumulate too much heat. Because the cooling surface of the subsequent cooling element dissipates the heat in time, the cooling surface of the cooling element will not be unable to dissipate more heat in time due to the high heat of the heating surface, thus affecting the efficiency of the cooling surface.

[0069] For example, the two stacked cooling and heat dissipation components 14 include a first cooling chip 140, a first heat sink 141, a second cooling chip 142, and a second heat sink 143 stacked sequentially. The cooling surface area of ​​the second cooling chip 142 is larger than that of the cooling surface area of ​​the first cooling chip 140. The second cooling chip 142 can dissipate the heat generated by the heating surface of the first cooling chip 140 in a timely manner, ensuring that the cooling surface of the first cooling chip can continuously cool.

[0070] Please combine further Figure 3 The lighting mechanism 11 includes a lamp tube 110 and a reflector cup 111 disposed on the side of the lamp tube 110 away from the light-transmitting crystal 12. An insulating heat sink 15 is disposed between the reflector cup 111 and the heat dissipation device 13.

[0071] Understandably, the reflector 111 is used to focus the light, allowing it to concentrate on the light-transmitting crystal 12. Therefore, a large amount of heat accumulates on the reflector 111. The insulating heat sink 15 positioned between the reflector 111 and the heat dissipation device 13 effectively dissipates heat from the reflector 111. When the lamp tube 110 generates heat, the insulating heat sink 15 effectively absorbs and conducts this heat, helping the heat dissipation device 13 to dissipate heat more effectively and maintain the appropriate temperature of the lighting mechanism 11, thereby improving the stability and reliability of the equipment. Simultaneously, the insulating heat sink 15 also serves as insulation, preventing short circuits between internal components of the hair removal device 1.

[0072] Furthermore, please combine Figure 2 , Figure 3 and Figure 4 The insulating heat sink 15 is attached to the reflector cup 111, or the insulating heat sink 15 is attached to the heat dissipation device 13.

[0073] Understandably, the insulating heat sink 15 is attached to the reflector cup 111, which not only serves to dissipate heat and provide insulation, but also to fix the lamp tube 110 and the reflector cup 111 in place, thereby improving the light emission effect. The insulating heat sink 15 is attached to the heat dissipation device 13, which can effectively increase the heat dissipation area and further improve the heat dissipation efficiency and insulation effect.

[0074] Understandably, when the insulating heat sink 15 is attached to the reflector cup 111, the insulating heat sink is specifically a ceramic insulating heat sink. When the insulating heat sink 15 is attached to the heat dissipation device 13, the insulating heat sink 15 can be a ceramic insulating heat sink, a plastic insulating heat sink, or other insulating heat sinks.

[0075] Understandably, in this embodiment, the specific shape of the insulating heat sink 15 is not limited, as long as it can be fitted and set with the reflector cup 111 or the insulating heat sink 15.

[0076] Please continue reading. Figure 4 A filter 16 is also provided between the light-transmitting crystal 12 and the light-emitting mechanism 11.

[0077] Understandably, the filter 16 serves a filtering function, selectively allowing light of a specific wavelength to pass through, ensuring that only light of the appropriate wavelength reaches the skin surface, thereby reducing adverse effects on the skin.

[0078] For further information, please refer to [link / reference]. Figure 4 The light-transmitting crystal 12 includes a light-incident surface 120 facing the light-emitting mechanism 11, a light-emitting surface 121 away from the light-emitting mechanism 11, and four side surfaces connecting the light-incident surface 120 and the light-emitting surface 121, with the four side surfaces covered by a silicone coating layer 122.

[0079] Understandably, when users perform hair removal, they typically apply gel to their skin. The silicone encapsulation layer 122 acts as a local seal, preventing gel from leaking into the hair removal device 1 and causing malfunctions. Furthermore, the silicone encapsulation layer 122 has low thermal conductivity, and the large area of ​​the transparent crystal 12 encapsulated by it reduces the cooling loss of the cooling element, thus enhancing its cooling effect. In addition, the silicone encapsulation layer 122 effectively prevents condensation from forming in the gaps between the transparent crystal 12 and other components after assembly, effectively protecting the sensing elements inside the hair removal device 1.

[0080] Furthermore, a first bracket 17 is provided outside the silicone coating layer 122, which is used to fix the lighting mechanism 11 and the light-transmitting crystal 12.

[0081] Understandably, the first support 17 also provides thermal insulation to prevent the heat generated by the light-emitting mechanism 11 from being directly transferred to the surrounding outer shell 10 and the light-transmitting crystal 12, thereby keeping the working temperature of the hair removal device 1 within an appropriate range and preventing the outer shell from burning the user.

[0082] Furthermore, the silicone encapsulation layer 122 and the first support 17 have a first opening 170, and the cooling chip near the light-transmitting crystal 12 at least partially passes through the first opening 170 and contacts the light-transmitting crystal 12.

[0083] Understandably, the silicone coating layer 122 and the first opening 170 on the first support 17 are matched with each other. The cooling chip close to the light-transmitting crystal 12 can directly contact the light-transmitting crystal through the first opening 170, which can effectively cool the crystal. The silicone coating layer 122 can prevent condensation from forming when the cooling chip is cooling and entering the gaps between the components.

[0084] Please combine further Figure 5 and Figure 6 The hair removal device 1 also includes a second support 18, which has a second opening 180. The heat dissipation component near the outer casing 10 contacts the heat dissipation device 13 at the second opening 180.

[0085] For example, the two stacked cooling and heat dissipation components 14 include a first cooling chip 140, a first heat sink 141, a second cooling chip 142, and a second heat sink 143 stacked in sequence. The second heat sink 143 contacts the heat dissipation device 13 at the second opening 180. The second heat sink 143 can transfer heat to the heat dissipation device 13, so that the heat dissipation device 13 can share the heat dissipation and effectively improve the overall heat dissipation efficiency.

[0086] Furthermore, the second bracket 18 is hollow and forms a first cavity 181 and a second cavity 182. The first cavity 181 and the second cavity 182 are connected. The lighting mechanism 11 is disposed in the first cavity 181, and the heat dissipation device 13 is disposed in the second cavity 182.

[0087] Understandably, the second bracket 18 is used to fix the light-emitting mechanism 11 and the heat dissipation device 13 relatively, which can ensure that each component is properly arranged in a compact space, does not affect each other during operation, and plays a role in anti-collision protection. At the same time, it can isolate dust and impurities in the external environment to a certain extent and maintain the cleanliness of the inside of the hair removal device 1.

[0088] Understandably, the first bracket 17 and the second bracket 18 are detachably connected to achieve relative fixation. In this embodiment, the connection method between the first bracket 17 and the second bracket 18 is not specifically limited.

[0089] For further information, please refer to [link / reference]. Figure 7 The hair removal device 1 also includes a fan assembly 19, which includes a volute 190, a fan 191 located inside the volute 190, and a connecting structure 192. The connecting structure 192 is provided with an air distribution plate 1921, and the end of the air distribution plate 1921 facing the heat dissipation device 13 is inclined toward the second cavity 182.

[0090] Understandably, in this embodiment, the housing 10 has an air inlet 102 at one end near the fan assembly 19 and an air outlet 101 at the other end near the heat dissipation device 13. The fan assembly 19 introduces fresh air through the air inlet 102 and delivers it to the area of ​​the heat dissipation device 13 within the second bracket 18. The generated heat is carried away by the airflow and blown out from the air outlet 101, thereby maintaining the equipment operating within an appropriate temperature range.

[0091] Understandably, the end of the air distribution plate 1921 facing the heat dissipation device 13 is inclined towards the second cavity 182, guiding the airflow in a specific direction to prevent overheating in localized areas of the device, ensuring that air effectively contacts the surface of the heat dissipation device 13, and improving heat transfer efficiency. The fan assembly 19 helps reduce the internal temperature of the device while easing the burden on the heat dissipation device 13, and works in tandem with the heat dissipation device 13 and other components to maximize the performance and stability of the hair removal device 1.

[0092] For details, please continue reading Figure 6 In this embodiment, a third cavity 1431 is provided near the heat sink of the outer casing 10.

[0093] Understandably, the third cavity 1431 is set up to dissipate heat from the cooling chip of the previous layer while also serving as a heat insulation function, preventing a large amount of heat from the heat sink from being transferred to the outer casing 10, and preventing the outer casing 10 from getting too hot and burning the skin.

[0094] Please continue reading. Figure 6 and Figure 7 The air distribution plate 1921 separates the connecting structure 192 into a first air duct 193 facing the first cavity 181 and a second air duct 194 facing the second cavity 182.

[0095] Understandably, the air distribution plate 1921 divides the air drawn in by the fan assembly 19 into two different air ducts. The connecting structure 192 is connected to the second cavity 182. The second air duct 194 blows the air towards the heat dissipation device 13, carrying away the heat on the heat dissipation device 13. The first air duct 193 blows the air towards the lighting mechanism 11 in the first cavity 181, directly carrying away some of the heat on the lighting mechanism 11.

[0097] Compared with the prior art, the hair removal device provided by this utility model has the following advantages:

[0098] 1. The hair removal device provided in this embodiment emits high-energy light through a light-emitting mechanism. This light is conducted, adjusted, and focused by a translucent crystal before being applied to the skin to achieve hair removal. A heat dissipation device is used to dissipate heat from the components within the device, ensuring it operates within a suitable temperature range, maintaining its performance, and extending its lifespan. At least two sets of cooling and heat dissipation components have their cooling plates and heat sinks sequentially connected. The outer cooling plate dissipates heat from the heating surface of the inner cooling plate, preventing excessive heat buildup and maintaining optimal cooling. This efficiently cools the translucent crystal. The cooling effect of the cooling plate and the heat dissipation effect of the heat sink are sequentially transferred and ultimately contact the heat dissipation device, effectively improving the heat dissipation and cooling effect on the translucent crystal and minimizing the burning sensation during hair removal.

[0099] 2. In the hair removal device provided in this embodiment of the present invention, the cooling element of a group of cooling and heat dissipation components near the light-transmitting crystal is at least partially in contact with the light-transmitting crystal, while the heat dissipation element of a group of cooling and heat dissipation components away from the light-transmitting crystal is at least partially in contact with the heat dissipation device. The contact between the light-transmitting crystal and the cooling element helps to conduct the heat generated by the light-transmitting crystal in a timely and effective manner, and then through the heat dissipation element to the heat dissipation device, ensuring that the heat can be quickly transferred from the heat dissipation element to the heat dissipation device. This can effectively reduce the temperature of the light-transmitting crystal, prevent it from overheating, thereby ensuring the performance and stability of the crystal, facilitating multi-stage heat dissipation, reducing the accumulation of heat inside the system, and further enhancing the heat dissipation capacity.

[0100] 3. The hair removal device provided in this embodiment of the present invention further includes a first cooling plate, a first heat sink, a second cooling plate, and a second heat sink stacked sequentially. The first cooling plate is at least partially in contact with the light-transmitting crystal, and the second heat sink is at least partially in contact with the heat dissipation device. The cooling surface of the first cooling plate contacts the light-transmitting crystal for cooling, and the first heat sink is stacked on the heating surface of the first cooling plate for heat dissipation. Sequentially, the second cooling plate is stacked on top of the first heat sink, and the cooling surface of the second cooling plate contacts the first heat sink for further cooling. The second heat sink is stacked on the heating surface of the second cooling plate and is at least partially in contact with the heat dissipation device for further heat dissipation. The sequential stacking design of the first cooling plate, the first heat sink, the second cooling plate, and the second heat sink effectively improves the heat dissipation and cooling effect on the light-transmitting crystal, minimizing the burning sensation during hair removal.

[0101] 4. The hair removal device provided in this embodiment of the present invention has a heat dissipation component that is a heat exchange plate or a heat pipe, which can provide efficient heat dissipation performance. The heat exchange plate and the heat pipe can be designed in a compact side by side, which is suitable for space-constrained scenarios, and is especially suitable for small and handheld hair removal devices.

[0102] 5. In the hair removal device provided in this embodiment, the cooling surfaces of the cooling plates of multiple cooling and heat dissipation components are all arranged facing the light-transmitting crystal, and the area of ​​the cooling surface of the cooling plate increases sequentially along the direction away from the light-transmitting crystal. This prevents the heating surface of the cooling plate close to the light-transmitting crystal from accumulating too much heat, because the cooling surface of the subsequent cooling plate dissipates the heat in time. The cooling surface of the cooling plate will not be unable to dissipate more heat in time due to the high heat of the heating surface, thus affecting the efficiency of the cooling surface.

[0103] 6. The hair removal device provided in this embodiment of the present invention includes a light-emitting mechanism comprising a lamp tube and a reflector cup disposed on the side of the lamp tube away from the light-transmitting crystal. An insulating heat sink is disposed between the reflector cup and the heat dissipation device. The reflector cup focuses the light, making the light more concentrated on the light-transmitting crystal. Therefore, a large amount of heat will accumulate on the reflector cup. The insulating heat sink disposed between the reflector cup and the heat dissipation device can effectively dissipate heat from the reflector cup. When the lamp tube generates heat, the insulating heat sink can effectively absorb and conduct this heat, helping the heat dissipation device to dissipate heat more effectively and maintain the appropriate temperature of the light-emitting mechanism, thereby improving the stability and reliability of the device. At the same time, the insulating heat sink also plays an insulating role, preventing short circuits between internal components of the hair removal device.

[0104] 7. In the hair removal device provided in this embodiment of the utility model, the insulating heat sink is attached to the reflector cup, or the insulating heat sink is attached to the heat dissipation device. The insulating heat sink attached to the reflector cup not only provides heat dissipation and insulation but also serves to fix the light tube and reflector cup, preventing them from shaking and thus improving the light emission effect. The insulating heat sink attached to the heat dissipation device effectively increases the heat dissipation area, further improving heat dissipation efficiency and insulation effect.

[0105] 8. In the hair removal device provided in this embodiment of the present invention, a filter is also provided between the light-transmitting crystal and the light-emitting mechanism. The filter has the function of filtering and can selectively transmit light of a specific wavelength to ensure that only light of the appropriate wavelength can reach the skin surface, thereby reducing adverse effects on the skin.

[0106] 9. The hair removal device provided in this embodiment of the present invention includes a light-incident crystal comprising a light-incident surface facing the light-emitting mechanism, a light-emitting surface away from the light-emitting mechanism, and four side surfaces connecting the light-incident and light-emitting surfaces, all four side surfaces being covered with a silicone encapsulation layer. When users typically perform hair removal, they apply gel to their skin; the silicone encapsulation layer acts as a local seal, preventing gel leakage into the hair removal device and causing malfunctions. Furthermore, the silicone encapsulation layer has a low thermal conductivity, and the large area of ​​the light-incident crystal covered by the silicone encapsulation layer can reduce the cooling capacity loss of the cooling element, thus enhancing its cooling effect. In addition, the silicone encapsulation layer can effectively prevent the formation of condensation in the gaps between the light-incident crystal and other components after assembly, effectively protecting the sensing elements inside the hair removal device.

[0107] 10. The hair removal device provided in this embodiment of the present invention has a first bracket outside the silicone encapsulation layer. The first bracket is used to fix the light-emitting mechanism and the light-transmitting crystal, and can also provide a heat insulation effect to prevent the heat generated by the light-emitting mechanism from being directly transferred to the surrounding shell and the light-transmitting crystal, so as to keep the working temperature of the hair removal device within an appropriate range and prevent the shell from burning the user.

[0108] 11. In the hair removal device provided in this embodiment of the present invention, the silicone encapsulation layer and the first support have a first opening, and the cooling element near the light-transmitting crystal at least partially passes through the first opening and contacts the light-transmitting crystal. This design allows the cooling element to directly contact the light-transmitting crystal through the first opening, resulting in a better cooling effect.

[0109] 12. The hair removal device provided in this embodiment of the present invention also includes a second bracket. The second bracket has a second opening. The heat dissipation component near the outer shell 10 is in direct contact with the heat dissipation device at the second opening, thereby achieving a better heat dissipation effect.

[0110] 13. In the hair removal device provided in this embodiment of the present invention, the second bracket is hollowly arranged to form a first cavity and a second cavity, the first cavity and the second cavity are connected, the light-emitting mechanism is disposed in the first cavity, and the heat dissipation device is disposed in the second cavity. The second bracket is used to fix the light-emitting mechanism and the heat dissipation device relatively, ensuring that each component is properly arranged in a compact space, does not interfere with each other during operation, and plays a role in anti-collision protection. At the same time, it can isolate dust and impurities in the external environment to a certain extent, maintaining the cleanliness of the inside of the hair removal device.

[0111] 14. The hair removal device provided in this embodiment of the present invention further includes a fan assembly. The fan assembly includes a volute, a fan located within the volute, and a connecting structure. An air distribution plate is provided within the connecting structure, and the end of the air distribution plate facing the heat dissipation device is inclined towards the second cavity. The fan assembly can introduce fresh air and deliver it to the area of ​​the heat dissipation device within the second support. The airflow carries away the generated heat, thereby maintaining the device's operation within a suitable temperature range. The air distribution plate, inclined towards the second cavity at the end facing the heat dissipation device, guides the airflow in a specific direction, preventing overheating in localized areas of the device and ensuring effective contact between air and the surface of the heat dissipation device, thus improving heat transfer efficiency. The fan assembly helps reduce the internal temperature of the device while alleviating the burden on the heat dissipation device. Working in conjunction with the heat dissipation device and other components, it maximizes the performance and stability of the hair removal device.

[0112] 15. In the hair removal device provided in this embodiment of the present invention, the air distribution plate separates the connecting structure into a first air duct facing the first cavity and a second air duct facing the second cavity. This design allows the fan assembly to dissipate heat from both the light-emitting mechanism in the first cavity and the heat dissipation device in the second cavity, thereby achieving more efficient thermal management.

[0113] 16. In the hair removal device provided in this embodiment of the present invention, at least two sets of cooling and heat dissipation components, consisting of cooling plates and heat sinks, are stacked alternately in sequence. This design ensures that each cooling plate has a corresponding heat sink for timely heat dissipation, further improving the heat dissipation effect.

[0114] 17. The hair removal device provided in this embodiment of the present invention uses a ceramic insulating heat sink. Ceramic insulating heat sinks have excellent thermal conductivity, effectively conducting heat and rapidly reducing temperature to prevent overheating. Furthermore, ceramic insulating heat sinks possess superior electrical insulation properties, effectively preventing short circuits and ensuring device safety.
