Description

[Technical Field]

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

[0002] During operation, the high thermal conductivity of the sapphire crystal in the IPL hair removal device allows it to quickly conduct the absorbed heat. Combined with the heat dissipation system, this heat is transferred to the external surface of the device, effectively cooling it. However, in actual operation, the sapphire crystal is exposed on the side in contact with the user. After the first cooling cycle, the sapphire crystal exchanges heat with the outside, and the crystal heats up quickly. The time it can maintain a relatively cool temperature is short, which limits the performance of the hair removal device during high-frequency, rapid light application. This is because more energy and time are needed to re-cool the crystal before the second light application. Users need to wait for the crystal to re-cool before each application. Therefore, the crystal part of the hair removal device needs to be designed to retain heat. At the same time, in order to provide users with a better skin feel and to care for their skin during the light application, many hair removal device manufacturers recommend that users use hair removal gel. Apply the hair removal gel to the skin before applying the light. However, most hair removal devices do not consider the sealing design of the light outlet from the outside to the inside to prevent the gel from seeping into the interior and causing damage to the hair removal device. Even worse, moisture in the air will condense into small water droplets or mist when it comes into contact with the cooled sapphire crystal and remain on the sapphire surface. The accumulated water droplets will flow into the light outlet channel through the gap between the light-transmitting crystal and the shell, contaminating the light outlet channel and corroding the internal components. [Utility Model Content]

[0014] Preferably, the wrapping layer is applied to the four sides, exposing the light-emitting surface and the light-receiving surface.

[0015] Compared with the prior art, the hair removal device provided by this utility model has the following advantages:

[0016] 1. The hair removal device provided in this embodiment of the utility model has an outer shell that protects the internal components. The light-emitting mechanism is used to generate the light energy required for hair removal. The light-transmitting crystal conducts, adjusts, and focuses the light beam, allowing light to pass through and optimizing the hair removal effect. The wrapping layer is applied to the side of the light-transmitting crystal, covering at least one of the four sides of the light-transmitting crystal, providing good sealing performance, preventing external substances from entering the interior of the hair removal device, and to a certain extent dispersing or blocking the exchange of heat between the external environment and the light-transmitting crystal, providing conditions for the cooling requirements of the light-transmitting crystal, increasing the cooling time, shortening the cooling interval time of multiple irradiations of the hair removal device, and the large-area wrapping layer provides additional physical protection.

[0017] 2. In the hair removal device provided in this embodiment, the filter plays a role in filtering and adjusting the spectrum between the light-transmitting crystal and the light-emitting mechanism. It can selectively transmit light of a specific wavelength to ensure that only appropriate light energy reaches the skin surface, reducing adverse effects on the skin. The protruding part avoids direct contact between the filter and the light-transmitting crystal. The spaced filter gap ensures that the optical performance and function of the filter are not damaged. The filter gap also optimizes the light path of the light passing through the filter, reducing contamination and accumulation between the filter and the light-transmitting crystal.

[0018] 3. In the hair removal device provided in this embodiment, the user pre-applies gel to the skin before operation to increase the cooling sensation. The flange on the side of the outer casing corresponding to the light-emitting surface forms a closed area. The silicone material has good sealing properties, tightly wrapping the gap between the light-transmitting crystal and the sealing cover, preventing dust from entering and preventing gel from seeping into or flowing into the device, thus improving safety. The flange fills the gap between the outer shell and the light-transmitting crystal, preventing the side of the light-transmitting crystal from contacting the air in the external environment and preventing the generation of condensation. The good sealing properties of silicone also isolate the external environment from heat exchange with the light-transmitting crystal, playing a role in keeping the light-transmitting crystal cool. Silicone is also an electrical insulating material, which can play a role in electrical insulation protection. The sealing cover protects the optical or electronic components inside the hair removal device. The sealing cover has an opening that exposes part of the light-transmitting crystal to ensure that the light is transmitted from the light-emitting surface to the skin without being obstructed by the sealing cover.

[0019] 4. In the hair removal device provided in this embodiment, the silicone layer serves as a wrapping layer, which has excellent heat insulation properties, effectively preventing the high-temperature part from contacting the user's skin and reducing the risk of burns. The wrapping layer also serves as a sealant, preventing external moisture from entering the device, especially during prolonged use or cleaning of the hair removal device, thus reducing the penetration of gel.

[0020] 5. The hair removal device provided in this embodiment of the present invention has protrusions and slots that provide additional stability, ensuring that the connection between the wrapping layer and the filter is firm and reliable, preventing the filter wrapping layer from moving or loosening during use, protecting the internal components, and allowing the user to easily disassemble and reinstall the wrapping layer and filter if cleaning is required.

[0021] 6. In the hair removal device provided in this embodiment of the present invention, the first bracket serves as a structural support element, stabilizing the internal components of the hair removal device and ensuring that the wrapping layer, filter, light-transmitting crystal, and light-emitting mechanism maintain the correct relative positions during use to maintain the normal operation of the device; the hollow design of the first bracket forms a receiving cavity, providing a closed space to isolate and protect the light-transmitting crystal. The receiving cavity also provides a thermal insulation effect, preventing the heat generated by the light-emitting mechanism from being directly transferred to the surrounding shell and light-transmitting crystal, reducing the risk of overheating, maintaining the working temperature of the hair removal device within an appropriate range, and preventing the shell from burning the user; sufficient space is left in the first bracket, allowing the user to access the internal components for replacement or repair without disassembling the entire hair removal device.

[0022] 7. The hair removal device provided in this embodiment of the utility model dissipates or conducts the heat generated inside the hair removal device to prevent overheating. During the hair removal process, various electronic components generate a certain amount of heat, especially when components such as the light-emitting mechanism are working. The heat dissipation device provides a heat transfer channel to help effectively dissipate heat to the external environment, ensuring that the device operates within an appropriate temperature range, reducing the surface temperature of the device, reducing the risk of users coming into contact with high-temperature components, and improving safety. The second bracket includes a first cavity and a second cavity, with a built-in heat dissipation device. The first cavity and the second cavity support the heat transfer and dissipation of the heat dissipation device. The first cavity and the second cavity are connected on the side near the light-emitting mechanism. The spatial connection brings heat transfer, transferring more of the heat generated by the light-emitting mechanism to the side of the second bracket away from the light-emitting surface, avoiding excessive heat transfer to the light-transmitting crystal. The first cavity and the second cavity make effective use of the space inside the main body, isolating the heat dissipation device and the light-emitting mechanism in different cavities. Each component is appropriately arranged in a compact space, improving space utilization efficiency. The weight felt by the user when holding the hair removal device is more even.

[0023] 8. The hair removal device provided in this embodiment of the utility model has a connecting structure that is connected to the first cavity. The fan assembly can introduce fresh air and deliver it to the area of ​​the heat dissipation device in the second bracket. The generated heat is carried away by the airflow, thereby maintaining the device in an appropriate temperature range. The air distribution plate is tilted towards one end of the heat dissipation device to guide the airflow in a specific direction, maintain temperature balance, prevent overheating in local areas of the device, ensure that the air effectively contacts the surface of the heat dissipation device, improve heat transfer efficiency, and introduce external air for heat dissipation. The fan assembly helps to reduce the internal temperature of the device while reducing the burden on the heat dissipation device, thus playing an energy-saving role. The coordinated work of the fan assembly, the heat dissipation device, and other components provides a comprehensive system design that maximizes the performance and stability of the hair removal device.

[0024] 9. The hair removal device provided in this embodiment of the utility model has an air outlet that allows the heat inside the hair removal device to be released to the external environment through the heat dissipation device to complete heat discharge and circulation, promotes air circulation, and maintains ventilation inside the device; the connecting structure introduces fresh air to cool the heat dissipation device, while the air outlet allows hot air to be discharged, maintaining heat balance, keeping the temperature of the device within the ideal range, ensuring that the device still maintains efficient operation during long-term use, reducing the temperature of the external surface of the device, and improving the safety and comfort of users when contacting the device.

[0025] 10. The hair removal device provided in this embodiment of the utility model has a reflector cup that focuses the light so that the light is more concentrated on the light-transmitting crystal. The light energy is focused, and the ceramic heat sink is located between the reflector cup and the heat dissipation device. Heat is conducted and dissipated. When the lamp tube generates heat, the ceramic 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.

[0026] 11. In the hair removal device provided in this embodiment of the present invention, the light-incident surface faces the light-emitting mechanism, and the light-exiting surface faces away from the light-emitting mechanism. The encapsulation layer exposes the light-exiting and light-incident surfaces to release the light emitted by the light-emitting mechanism, ensuring the normal operation of the hair removal device. Furthermore, the encapsulation layer exposing the light-incident and light-exiting surfaces helps to enhance the heat dissipation effect and avoid heat concentration near the encapsulation layer. The encapsulation layer covers the four sides of the light-transmitting crystal, increasing the sealing area, enhancing protection, and improving the durability of the light-transmitting crystal.

[0044] Please combine Figure 1 - Figure 3 The hair removal device 1 includes a housing 12 and a main body 11 disposed in the housing 12. The main body 11 includes a light-emitting mechanism 111 and a light-transmitting crystal 112. The side of the light-transmitting crystal 112 facing the light-emitting mechanism 111 is defined as the light-incident surface 1121, the side away from the light-emitting mechanism 111 is defined as the light-emitting surface 1122, and the other four sides are the side surfaces. The light emitted by the light-emitting mechanism 111 passes through the light-incident surface 1121 and the light-emitting surface 1122 in sequence. The light-transmitting crystal 112 is surrounded by a covering layer 114 on the four side surfaces. The main body 11 also includes a cooling and heat dissipation component 119 disposed on one side corresponding to at least one side of the light-transmitting crystal 112. The cooling and heat dissipation component 119 partially passes through the covering layer 114 and comes into contact with the light-transmitting crystal 112.

[0045] The light-transmitting crystal 112 includes a light-incident surface 1121 facing the light-emitting mechanism 111, a light-emitting surface 1122 away from the light-emitting mechanism 111, and four other side surfaces. The main body also includes an encapsulation layer 114, which is disposed on at least one of the four side surfaces.

[0046] Furthermore, a cooling opening 1143 is provided on the wrapping layer 114 corresponding to the cooling and heat dissipation component 119. The cooling and heat dissipation component 119 passes through the cooling opening 1143 and contacts the light-transmitting crystal 112. The cooling and heat dissipation component 119 absorbs the heat on the light-transmitting crystal 112 and rapidly cools the light-transmitting crystal 112, providing a cool skin feel. A more efficient heat-conducting material is selected to manufacture the cooling and heat dissipation component 119, such as copper or aluminum, to improve the heat conduction efficiency. The cooling and heat dissipation component 119 includes at least one cooling plate, which is at least partially in contact with the light-transmitting crystal 112.

[0047] Understandably, the outer shell 12 protects the internal components, the light-emitting mechanism 111 generates the light energy required for hair removal, the light-transmitting crystal 112 conducts, adjusts, and focuses the light beam, allowing light to pass through, and the covering layer 114 is fitted on the sides of the light-transmitting crystal 112, covering the four sides of the light-transmitting crystal 112 and exposing the light-entry surface 1121 and the light-exit surface 1122, providing good sealing performance, dispersing or blocking the exchange of heat from the external environment with the light-transmitting crystal 112, increasing the cooling time of the light-transmitting crystal 112, and shortening the cooling interval time between multiple irradiations of the hair removal device 1; in addition, the cooling and heat dissipation component 119 partially passes through the covering layer 114 and contacts the light-transmitting crystal 112, absorbing the heat on the light-transmitting crystal 112, rapidly cooling the light-transmitting crystal 112, and providing a cool skin feel.

[0048] To facilitate cleaning and maintenance, the outer shell 12 is designed as a detachable structure to seal the main body 11. The outer shell also has two opposite heat dissipation vents corresponding to the lighting mechanism to prevent heat buildup around the lighting mechanism during operation. Specifically, the light-transmitting crystal 112 is made of sapphire material with a low thermal conductivity to isolate the heat generated by the lighting mechanism 111.

[0049] Further, please refer to Figure 1 The main body 11 includes a filter 113 disposed between the light-emitting mechanism 111 and the light-transmitting crystal 112, and there is a filter gap 1132 between the filter 113 and the light-transmitting crystal 112; the wrapping layer 114 has a protrusion 1141 at one end corresponding to the light-incident surface 1121, and the protrusion 1141 seals the filter gap 1132 to form a closed gap.

[0050] Understandably, a filter gap 1132 is created between the light-transmitting crystal 112 and the filter 113. The light-transmitting crystal 112 has a protrusion 1141 facing the filter 113. The protrusion 1141 closes the filter gap 1132. The filter gap 1132 allows light to be optically adjusted before entering the light-transmitting crystal 112. At the same time, the closed gap can prevent water and fog from condensing inside.

[0051] Furthermore, the encapsulation layer 114 is a silicone layer, or the encapsulation layer 114 is a sealant.

[0052] Further, please refer to Figure 4 The wrapping layer 114 has a protrusion 1142 facing the filter 113, and the filter 113 has a slot 1131 corresponding to the protrusion 1142.

[0053] Optionally, in this embodiment, the purpose of the protrusion 1142 engaging with the slot 1131 is to connect the wrapping layer 114 and the filter 113. To achieve this purpose, snap-fit, pin and slot engagement, or magnetic engagement can also be used, which is not limited here.

[0054] Further, please refer to Figure 3 The outer casing 12 includes a sealing cover 121, which is disposed corresponding to the light-emitting surface 1122. The wrapping layer 114 has a flange 1144 at one end corresponding to the light-emitting surface 1122, which seals the gap between the light-transmitting crystal 112 and the sealing cover 121.

[0055] Furthermore, the sealing cover 121 has an opening 1211 that exposes part of the light-transmitting crystal 112.

[0056] Understandably, the sealing cover 121 prevents dust, moisture, or other impurities from entering the hair removal device 1 from the light-emitting surface 1122 of the light-transmitting crystal 112. The opening 1211 on the sealing cover 121 needs to expose part of the light-transmitting crystal 112 to ensure that light is transmitted from the light-emitting surface 1122 to the external environment. The light-emitting surface 1122 of the light-transmitting crystal 112 needs to be in direct contact with the user's skin to achieve the purpose of light emission and to prevent the user's eyes from looking directly at the light-emitting surface 1122. Therefore, the sealing cover 121 needs to be sealed with the wrapping layer 114 to prevent the openness of the opening 1211 from causing damage to the hair removal device 1. The wrapping layer 114 fills the gap between the light-transmitting crystal 112 and the outer shell 12, effectively preventing moisture or water vapor in the external air from penetrating this gap and preventing the possibility of water vapor condensing on the side of the light-transmitting crystal 112 to form condensate.

[0057] Specifically, the wrapping layer 114 has a flange 1144 on one side corresponding to the light-emitting surface 1122, which directly abuts against the sealing cover 121 to form a closed area. The silicone material has good sealing properties, tightly wrapping the gap between the light-transmitting crystal 112 and the sealing cover 121, preventing dust from entering and preventing the maintenance gel from soaking or flowing into the device. At the same time, it isolates the external environment from exchanging heat with the light-transmitting crystal 112, thus keeping the light-transmitting crystal 112 cool. Silicone is also an electrical insulating material, which can play a role in electrical insulation protection.

[0058] Specifically, the sealing cap 121 and the wrapping layer 114 can be fitted with the same protrusion 1142 and groove 1131 as the wrapping layer 114 and the filter 113, or they can be connected by snap-fit ​​or threaded connection and a rubber sealing strip or rubber gasket can be added to enhance the sealing performance.

[0059] Further, please refer to Figure 5 The hair removal device 1 has a first support 116 inside the main body 11. The first support 116 is hollow to form a receiving cavity 1161. The wrapping layer 114, the filter 113 and the light-transmitting crystal 112 are disposed inside the receiving cavity 1161.

[0060] Understandably, the first support 116 serves as a structural support element to ensure that the wrapping layer 114, the filter 113, and the light-transmitting crystal 112 maintain the correct relative positions during use. The hollow design of the first support 116 forms a receiving cavity 1161, providing a closed space to isolate and protect the light-transmitting crystal 112.

[0061] Specifically, the receiving cavity 1161 is provided with a light-transmitting crystal 112, a wrapping layer 114 and a filter 113, which are arranged sequentially in the receiving cavity 1161 along the width direction of the hair removal device 1. There is a filter gap 1132 between the filter 113 and the light-transmitting crystal 112. The wrapping layer 114 wraps the four sides of the light-transmitting crystal 112 and has a protrusion 1141 on the side near the filter 113. The protrusion 1141 seals the filter gap 1132.

[0062] Furthermore, the filter 113 is connected to the first support 116. The area of ​​the filter 113 needs to be equal to the area of ​​the receiving cavity 1161 near the light-incident surface 1121, completely covering the open area of ​​the receiving cavity 1161 near the light-incident surface 1121. The filter 113, the wrapping layer 114, and the sealing cap 121 are arranged sequentially from the light-incident surface 1121 to the light-emitting surface 1122, fitting tightly together. The first support 116 wraps around and covers the filter 113 and the wrapping layer 114, forming a receiving cavity 1161 with an open space facing the light-emitting surface 1122, providing a good sealed space for the light-transmitting crystal 112.

[0063] Furthermore, the main body 11 of the hair removal device 1 also includes a heat dissipation device 115, which is located on the side of the light-emitting mechanism 111 away from the filter 113.

[0064] Furthermore, the heat dissipation device 115 includes at least two spaced-apart sheet-like heat sinks 1151, with heat dissipation gaps between each pair of sheet-like heat sinks 1151. Understandably, the heat dissipation device 115 dissipates or conducts heat generated inside the hair removal device 1 to prevent the hair removal device 1 from overheating. The heat dissipation device 115 includes at least two spaced-apart sheet-like heat sinks 1151, which can be made of highly thermally conductive materials, such as aluminum, copper, or other alloys, to effectively absorb and dissipate heat. There are heat dissipation gaps between adjacent sheet-like heat sinks 1151, which provide a channel for air circulation.

[0065] Specifically, in addition to the finned heat sink 1151, heat pipes can also be used, with liquid coolant circulating inside the heat pipes to effectively dissipate heat, or a heat sink fin design can be adopted, by changing the shape and structure of the heat dissipation device 115 to increase the heat dissipation surface area.

[0066] Furthermore, a second support 117 is provided inside the main body 11 of the hair removal device 1. The second support 117 includes a first cavity 1171 and a second cavity 1172. A heat dissipation device 115 is provided inside the second cavity 1172. A light-emitting mechanism 111 is provided inside the first cavity 1171. The first cavity 1171 and the second cavity 1172 are connected on the side near the light-emitting mechanism 111.

[0067] Furthermore, the lighting mechanism 111 includes a lamp tube 1111 and a reflector cup 1112 disposed on the side of the lamp tube 1111 away from the light-transmitting crystal 112. A ceramic heat sink 1113 is disposed between the reflector cup 1112 and the heat dissipation device 115.

[0068] Understandably, the reflector cup 1112 optimizes the reflection of light to ensure that the light is effectively focused onto the light-transmitting crystal 112. In this embodiment, the reflector cup 1112 adopts a shape that is concave to the lamp tube 1111. Its reflective surface area should be adapted to the length and diameter of the lamp tube 1111 and the accommodating space of the first cavity 1171. Furthermore, in order to achieve a better light-concentrating effect, a high-efficiency reflective coating can be applied to the surface of the reflector cup 1112 or reflective elements can be added.

[0069] Specifically, the lamp tube 1111 is inserted into the reflector cup 1112. When the lamp tube 1111 starts working and emits light, part of the light passes directly through the filter 113 and shines onto the light-incident surface 1121 of the light-transmitting crystal 112. The light passes through the light-transmitting crystal 112 and shines onto the area to be treated from the light-emitting surface 1122. Part of the light is focused by the reflector cup 1112 and then passes through the filter 113 to concentrate the light onto the light-transmitting crystal 112. On the light-transmitting crystal 112, the light emitted by the lighting mechanism 111 passes through the light-incident surface 1121 and the light-emitting surface 1122 in sequence and is then emitted. The ceramic heat sink 1113 is located between the reflector cup 1112 and the heat dissipation device 115. The ceramic heat sink 1113 can effectively absorb and conduct heat, helping the lamp tube 1111 and the reflector cup 1112 to dissipate heat.

[0070] Optionally, the ceramic heat sink 1113 can be attached to the reflector cup 1112 or the heat dissipation device 115. In this embodiment, the specific location of the ceramic heat sink 1113 is not limited, as long as it can achieve the purpose of improving heat dissipation efficiency and insulation effect.

[0071] Understandably, the lighting mechanism 111 is located in the first cavity 1171. The first cavity 1171 and the second cavity 1172 are connected on the side near the lighting mechanism 111. A heat dissipation device 115 is provided in the second cavity 1172. The air in the second cavity 1172 and the first cavity 1171 can circulate freely, resulting in more efficient heat dissipation.

[0072] Further, please refer to Figure 5 The main body 11 of the hair removal device 1 is also provided with a fan assembly 118. The fan assembly 118 includes a connecting structure 1181. The connecting structure 1181 is located at one end near the heat dissipation device 115 and communicates with the second cavity 1172. The connecting structure 1181 is provided with an air distribution plate 1182. The air distribution plate 1182 is inclined towards the first cavity 1171 at one end facing the heat dissipation device 115.

[0073] Specifically, the air distribution plate 1182 divides the air drawn in by the fan into two different channels. The connecting structure 1181 is connected to the second cavity 1172. One air channel blows the air towards the heat dissipation device 115, carrying away the heat on the heat dissipation device 115; the other air channel blows the air towards the lighting mechanism 111 in the first cavity 1171, directly carrying away some of the heat on the lighting mechanism 111.

[0074] Furthermore, an air outlet 1212 is provided on the side of the outer casing 12 corresponding to the heat dissipation device 115 away from the fan assembly 118, and the air outlet 1212 is connected to the heat dissipation device 115 and the connecting structure 1181.

[0075] Specifically, please refer to Figure 6 The airflow direction inside the hair removal device 1 is shown in the figure. The fan assembly 118 also includes a volute 1183 and a fan 1184 inside the volute 1183. The top of the fan 1184 is provided with an air inlet 1185. The outer shell 12 that encloses the fan assembly 118 is provided with an air inlet 1213 corresponding to the air inlet 1185. The air enters the volute 1183 from the air inlet 1213 and connects to the air inlet 1185. The fan 1184 inside the volute 1183 rotates and drives the airflow. The air enters the connecting structure 1181 and is divided into two different air channels by the air distribution plate 1182. Fresh air is brought to the light-emitting mechanism 111 and the heat dissipation device 115 respectively, and the air carrying heat is discharged from the air outlet 1212.

[0076] Understandably, the air outlet 1212 allows the heat inside the hair removal device 1 to be released to the external environment through the heat dissipation device 115 to complete heat dissipation and circulation, promote air circulation, and maintain ventilation inside the device; the connection structure 1181 introduces fresh air to cool the heat dissipation device 115, while the air outlet 1212 allows hot air to be discharged.

[0077] Further, please refer to Figure 1The cooling and heat dissipation assembly 119 comprises at least two sets, each including a cooling chip 1191 and a heat sink 1192. The cooling chips 1191 and heat sinks 1192 of the at least two sets of cooling and heat dissipation assemblies 119 are stacked alternately in sequence. The cooling chip 1191 of the set of cooling and heat dissipation assemblies 119 closest to the light-transmitting crystal 112 is at least partially in contact with the light-transmitting crystal 112, and the heat sink 1192 of the set of cooling and heat dissipation assemblies 119 furthest from the light-transmitting crystal 112 is at least partially in contact with the heat dissipation device 115.

[0078] Understandably, at least two sets of cooling and heat dissipation components 119 have their cooling plates 1191 and heat sinks 1192 stacked alternately in sequence. The cooling plates 1191 of the set of cooling and heat dissipation components 119 closest to the light-transmitting crystal 112 are at least partially in contact with the light-transmitting crystal 112, while the heat sinks 1192 of the set of cooling and heat dissipation components 119 furthest from the light-transmitting crystal 112 are at least partially in contact with the heat dissipation device 115. The outer cooling plate 1191 can dissipate heat from the heating surface of the inner cooling plate 1191 in a timely manner, preventing excessive heat accumulation and maintaining optimal cooling performance. This efficiently cools the light-transmitting crystal. The cooling effect of the cooling plate 1191 and the heat dissipation effect of the heat sink 1192 are sequentially transferred and ultimately come into contact with the heat dissipation device 115, effectively improving the heat dissipation and cooling effect on the light-transmitting crystal and minimizing the burning sensation during hair removal.

[0079] Furthermore, the heat sink 1192 is a vapor chamber heat sink or a heat pipe heat sink.

[0080] Understandably, heat spreader or heat pipe heat sink can effectively optimize the heat conduction path, minimize thermal resistance, remove heat from the cooling chip, and prevent overheating inside the main body 11.

[0081] Compared with the prior art, the hair removal device provided by this utility model has the following advantages:

[0082] 1. The hair removal device provided in this embodiment of the utility model has an outer shell that protects the internal components. The light-emitting mechanism is used to generate the light energy required for hair removal. The light-transmitting crystal conducts, adjusts, and focuses the light beam, allowing light to pass through and optimizing the hair removal effect. The wrapping layer is applied to the side of the light-transmitting crystal, covering at least one of the four sides of the light-transmitting crystal, providing good sealing performance, preventing external substances from entering the interior of the hair removal device, and to a certain extent dispersing or blocking the exchange of heat between the external environment and the light-transmitting crystal, providing conditions for the cooling requirements of the light-transmitting crystal, increasing the cooling time, shortening the cooling interval time of multiple irradiations of the hair removal device, and the large-area wrapping layer provides additional physical protection.

[0083] 2. In the hair removal device provided in this embodiment, the filter plays a role in filtering and adjusting the spectrum between the light-transmitting crystal and the light-emitting mechanism. It can selectively transmit light of a specific wavelength to ensure that only appropriate light energy reaches the skin surface, reducing adverse effects on the skin. The protruding part avoids direct contact between the filter and the light-transmitting crystal. The spaced filter gap ensures that the optical performance and function of the filter are not damaged. The filter gap also optimizes the light path of the light passing through the filter, reducing contamination and accumulation between the filter and the light-transmitting crystal.

[0084] 3. In the hair removal device provided in this embodiment, the user pre-applies gel to the skin before operation to increase the cooling sensation. The flange on the side of the outer casing corresponding to the light-emitting surface forms a closed area. The silicone material has good sealing properties, tightly wrapping the gap between the light-transmitting crystal and the sealing cover, preventing dust from entering and preventing gel from seeping into or flowing into the device, thus improving safety. The flange fills the gap between the outer shell and the light-transmitting crystal, preventing the side of the light-transmitting crystal from contacting the air in the external environment and preventing the generation of condensation. The good sealing properties of silicone also isolate the external environment from heat exchange with the light-transmitting crystal, playing a role in keeping the light-transmitting crystal cool. Silicone is also an electrical insulating material, which can play a role in electrical insulation protection. The sealing cover protects the optical or electronic components inside the hair removal device. The sealing cover has an opening that exposes part of the light-transmitting crystal to ensure that the light is transmitted from the light-emitting surface to the skin without being obstructed by the sealing cover.

[0085] 4. In the hair removal device provided in this embodiment, the silicone layer serves as a wrapping layer, which has excellent heat insulation properties, effectively preventing the high-temperature part from contacting the user's skin and reducing the risk of burns. The wrapping layer also serves as a sealant, preventing external moisture from entering the device, especially during prolonged use or cleaning of the hair removal device, thus reducing the penetration of gel.

[0086] 5. The hair removal device provided in this embodiment of the present invention has protrusions and slots that provide additional stability, ensuring that the connection between the wrapping layer and the filter is firm and reliable, preventing the filter wrapping layer from moving or loosening during use, protecting the internal components, and allowing the user to easily disassemble and reinstall the wrapping layer and filter if cleaning is required.

[0087] 6. In the hair removal device provided in this embodiment of the present invention, the first bracket serves as a structural support element, stabilizing the internal components of the hair removal device and ensuring that the wrapping layer, filter, light-transmitting crystal, and light-emitting mechanism maintain the correct relative positions during use to maintain the normal operation of the device; the hollow design of the first bracket forms a receiving cavity, providing a closed space to isolate and protect the light-transmitting crystal. The receiving cavity also provides a thermal insulation effect, preventing the heat generated by the light-emitting mechanism from being directly transferred to the surrounding shell and light-transmitting crystal, reducing the risk of overheating, maintaining the working temperature of the hair removal device within an appropriate range, and preventing the shell from burning the user; sufficient space is left in the first bracket, allowing the user to access the internal components for replacement or repair without disassembling the entire hair removal device.

[0088] 7. The hair removal device provided in this embodiment of the utility model dissipates or conducts the heat generated inside the hair removal device to prevent overheating. During the hair removal process, various electronic components generate a certain amount of heat, especially when components such as the light-emitting mechanism are working. The heat dissipation device provides a heat transfer channel to help effectively dissipate heat to the external environment, ensuring that the device operates within an appropriate temperature range, reducing the surface temperature of the device, reducing the risk of users coming into contact with high-temperature components, and improving safety. The second bracket includes a first cavity and a second cavity, with a built-in heat dissipation device. The first cavity and the second cavity support the heat transfer and dissipation of the heat dissipation device. The first cavity and the second cavity are connected on the side near the light-emitting mechanism. The spatial connection brings heat transfer, transferring more of the heat generated by the light-emitting mechanism to the side of the second bracket away from the light-emitting surface, avoiding excessive heat transfer to the light-transmitting crystal. The first cavity and the second cavity make effective use of the space inside the main body, isolating the heat dissipation device and the light-emitting mechanism in different cavities. Each component is appropriately arranged in a compact space, improving space utilization efficiency. The weight felt by the user when holding the hair removal device is more even.

[0089] 8. The hair removal device provided in this embodiment of the utility model has a connecting structure that is connected to the first cavity. The fan assembly can introduce fresh air and deliver it to the area of ​​the heat dissipation device in the second bracket. The generated heat is carried away by the airflow, thereby maintaining the device in an appropriate temperature range. The air distribution plate is tilted towards one end of the heat dissipation device to guide the airflow in a specific direction, maintain temperature balance, prevent overheating in local areas of the device, ensure that the air effectively contacts the surface of the heat dissipation device, improve heat transfer efficiency, and introduce external air for heat dissipation. The fan assembly helps to reduce the internal temperature of the device while reducing the burden on the heat dissipation device, thus playing an energy-saving role. The coordinated work of the fan assembly, the heat dissipation device, and other components provides a comprehensive system design that maximizes the performance and stability of the hair removal device.

[0090] 9. The hair removal device provided in this embodiment of the utility model has an air outlet that allows the heat inside the hair removal device to be released to the external environment through the heat dissipation device to complete heat discharge and circulation, promotes air circulation, and maintains ventilation inside the device; the connecting structure introduces fresh air to cool the heat dissipation device, while the air outlet allows hot air to be discharged, maintaining heat balance, keeping the temperature of the device within the ideal range, ensuring that the device still maintains efficient operation during long-term use, reducing the temperature of the external surface of the device, and improving the safety and comfort of users when contacting the device.

[0091] 10. The hair removal device provided in this embodiment of the utility model has a reflector cup that focuses the light so that the light is more concentrated on the light-transmitting crystal. The light energy is focused, and the ceramic heat sink is located between the reflector cup and the heat dissipation device. Heat is conducted and dissipated. When the lamp tube generates heat, the ceramic 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.

[0092] 11. In the hair removal device provided in this embodiment of the present invention, the light-incident surface faces the light-emitting mechanism, and the light-exiting surface faces away from the light-emitting mechanism. The encapsulation layer exposes the light-exiting and light-incident surfaces to release the light emitted by the light-emitting mechanism, ensuring the normal operation of the hair removal device. Furthermore, the encapsulation layer exposing the light-incident and light-exiting surfaces helps to enhance the heat dissipation effect and avoid heat concentration near the encapsulation layer. The encapsulation layer covers the four sides of the light-transmitting crystal, increasing the sealing area, enhancing protection, and improving the durability of the light-transmitting crystal.

[0093] 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.
