Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a heat dissipation component and a hair removal device. Background Art

[0002] An epilator is an instrument that uses the principle of photothermal therapy to remove hair. It emits intense pulsed light of a specific wavelength, which acts directly on the roots of hair follicles through the pores, destroying the follicle tissue and causing the follicles to gradually shrink, thereby achieving the desired effect of hair removal. To ensure safety during the hair removal process, existing technologies have included heat sinks in epilators to dissipate heat. Existing heat sinks generally only collect heat from the cooling plate, which is then absorbed by the heat sink through a fan to dissipate heat from the epilator. However, due to the limited area of ​​the heat sink, frequent use of the epilator can cause heat to accumulate in the heat sink, resulting in low heat dissipation efficiency.

[0053] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0054] In one possible example, see Figures 1-4 , Figure 1 This is a structural diagram of a hair removal device provided in an embodiment of the present application; Figure 2 This is an exploded schematic diagram of a hair removal device provided in an embodiment of the present application; Figure 3 This is a schematic structural diagram of a heat dissipation assembly provided in an embodiment of the present application; Figure 4 This is a schematic diagram of the structure of another heat dissipation component provided in an embodiment of the present application. Figures 1-4 As shown, a heat dissipation component 2 is applied to a hair removal device, the hair removal device includes a housing 1 and the heat dissipation component 2 arranged in the inner cavity of the housing 1, the heat dissipation component 2 includes a support member, a cold compress member 23, a refrigeration member 24, a heat dissipation member 26 and a fan 25; please continue to combine Figure 5-Figure 8 , Figure 5 This is an exploded schematic diagram of a heat dissipation assembly provided in an embodiment of the present application; Figure 6 This is a schematic diagram of the assembly of a cold compress, a refrigeration component, and a heat dissipation component provided in an embodiment of the present application; Figure 7 This is a schematic diagram of an assembly of a refrigeration component and a heat dissipation component provided in an embodiment of the present application; Figure 8 This embodiment of the present application provides Figure 1The support member includes at least one heat dissipation duct, the air inlet of the at least one heat dissipation duct is connected to the air outlet 252 of the fan; Figure 6 As shown, the connection end 261 of the heat sink is arranged on the outer wall of the bottom of the support member, and the heat dissipation end 262 of the heat sink is placed in the first heat dissipation duct 27 of the support member, dividing the first heat dissipation duct 27 into a first heat dissipation sub-duct and a second heat dissipation sub-duct; the cold compress 23 is arranged at the light outlet of the support member, and the cold compress 23 is used to contact the user's skin when the hair removal device is in use for cold compress; the cooling end of the refrigeration member 24 is in contact with the cold compress 23, and the heat dissipation end of the refrigeration member 24 is in contact with the connection end 261 of the heat sink to transfer the heat of the refrigeration member 24 to the heat sink 26.

[0055] In this specific example, the hair removal device includes a housing 1, a control module 3, and a heat dissipation assembly 2. The housing 1 comprises an upper housing 11, a lower housing 12, and a head cover 13. The upper housing 11, lower housing 12, and head cover 13 combine to form a housing 1 comprising a cavity. The control module 3 and heat dissipation assembly 2 are disposed within the interior of the housing 1. The heat dissipation assembly 2 is located at the front end of the interior of the housing 1, allowing the light outlet of the heat dissipation assembly 2 to communicate with the light outlet hole of the head cover 13.

[0056] Please refer again Figure 5 and Figure 7 The support member includes at least one heat dissipation duct, and the air inlet of at least one heat dissipation duct is connected to the air outlet 252 of the fan, so that the fan 25 can direct air into the heat dissipation duct. The connection end 261 of the heat dissipation element is set on the outer wall of the bottom of the support member. A through hole is also opened at the bottom of the support member to connect the inner cavity of the shell 1 and the first heat dissipation duct. The heat dissipation end 262 of the heat dissipation element is inserted into the first heat dissipation duct 27 of the support member through the through hole, dividing the first heat dissipation duct 27 into a first heat dissipation sub-duct and a second heat dissipation sub-duct, thereby increasing the number of heat dissipation ducts. That is, a three-duct structure of a first heat dissipation sub-duct, a second heat dissipation sub-duct, and a second heat dissipation duct 28 is formed in the hair removal device. The heat dissipation end 262 of the heat dissipation element is located in different heat dissipation sub-ducts, thereby improving heat dissipation efficiency.

[0057] Please refer again to Figure 8 The cold compress 23 is arranged at the light outlet of the support member, and the cold compress 23 abuts the cooling end of the refrigeration member 24, and the heat dissipation end of the refrigeration member 24 abuts the connection end 261 of the heat dissipation member, so that the refrigeration member 24 transfers the heat of the refrigeration member 24 to the heat dissipation member 26.

[0058] It can be seen that in this example, the heat dissipation duct is divided into multiple heat dissipation sub-ducts by the heat dissipation element 26, and the heat dissipation parts of the heat dissipation element 26 are respectively arranged in different heat dissipation sub-ducts to avoid the heat dissipation of the heat dissipation parts affecting each other, and increase the contact area between the heat dissipation element 26 and the air, thereby improving the heat dissipation efficiency.

[0059] In a possible example, the refrigeration component 24 includes a first thermally conductive silicone component 241, a refrigeration component 242 and a second thermally conductive silicone component 243; the refrigeration end of the refrigeration component 242 abuts against the cold compress component 23 through the first thermally conductive silicone component 241, and the heat dissipation end of the refrigeration component 242 abuts against the connection end 261 of the heat dissipation component through the second thermally conductive silicone component 243.

[0060] For a specific example, see Figure 6 and Figure 7 ,like Figure 6 and Figure 7 As shown, the refrigeration component 24 includes a first thermally conductive silicone component 241, a refrigeration component 242 and a second thermally conductive silicone component 243. The refrigeration component 242 is in contact with the cold compress 23 through the first thermally conductive silicone component 241, and the refrigeration component 242 is in contact with the connecting end 261 of the heat sink through the second thermally conductive silicone component 243, so that the connection between the cold compress 23, the refrigeration component 242 and the heat sink 26 is tighter, allowing the refrigeration component 24 to reduce the heat of the cold compress 23, and the heat on the refrigeration component 24 is quickly transferred to the heat sink 26.

[0061] It can be seen that in this example, heat-conducting silicone components are provided at both ends of the refrigeration element 24 that abut against the cold compress element 23 and the heat dissipation element 26 , thereby improving the heat conduction efficiency of the refrigeration element 24 .

[0062] In one possible example, see Figure 5 The support member includes a heat sink mounting member 51, and the heat sink mounting member 51 is fixedly mounted on the outer wall of the bottom of the support member; Figure 7 and Figure 8 The connection end 261 of the heat sink is arranged on the outer wall of the bottom of the support member through the heat sink mounting component 51, so that the heat sink 26 is separated from the outer wall of the bottom of the support member. The connection end 261 of the heat sink is arranged around the outer wall of the bottom of the support member. The heat dissipation end 262 of the heat sink is provided with a first heat dissipation fin group 2621 and a second heat dissipation fin group 2622. The first heat dissipation fin group 2621 is located in the first heat dissipation sub-duct, and the second heat dissipation fin group 2622 is located in the second heat dissipation sub-duct. An air duct is formed between every two adjacent fins in the first heat dissipation fin group 2621, and the air inlet of the air duct is opposite to the air outlet of the fan. The fins in the second heat dissipation fin group 2622 extend from the bottom of the support member toward the bottom of the housing 1.

[0063] In a specific example, a heat sink mounting component 51 is provided on the outer wall of the bottom of the support member. Specifically, the heat sink mounting component 51 can be a mounting post, which can be perpendicular to the outer wall of the bottom of the support member. A mounting hole is provided on the connecting end 261 of the heat sink, which mates with the mounting post. The cross-sectional diameter of the end of the mounting post connected to the bottom of the support member is larger than the diameter of the mounting hole. This allows the heat sink 26 to be separated from the outer wall of the bottom of the support member when it is mounted on the mounting post through the mounting hole. This reduces the contact area between the heat sink 26 and the support member, thereby reducing heat conduction and further reducing the impact of the heat from the heat sink 26 on other components within the hair removal device. A threaded hole is provided in the mounting post, which mates with a first screw 52. When the heat sink 26 is mounted on the mounting post, the first screw 52 is inserted into the mounting hole and mates with the threaded hole, thereby securing the heat sink 26. It is understood that two or more heat sink mounting components 51 can be provided to further improve the stability of the heat sink 26. Alternatively, the heat sink mounting component 51 may be configured in other shapes, such as a triangular prism, to prevent the heat sink from shaking and improve the stability of the heat sink 26 .

[0064] In a possible example, a limit member can also be set on the outer wall of the bottom of the support member, and a limit groove that cooperates with the limit member is opened on the heat sink 26. When the heat sink 26 is installed on the mounting column through the mounting through hole, the limit groove cooperates with the limit member, thereby limiting the displacement of the heat sink 26 and improving the stability of the heat sink 26.

[0065] Please continue to combine Figure 7 and Figure 8 ,like Figure 7 As shown, the connection end 261 of the heat sink is arranged around the outer wall of the bottom of the support member, further reducing the contact area with the support member. The heat dissipation end 262 of the heat sink is provided with a first heat dissipation fin group 2621 and a second heat dissipation fin group 2622. The first heat dissipation fin group 2621 is located in the first heat dissipation sub-duct, and the second heat dissipation fin group 2622 is located in the second heat dissipation sub-duct. The first heat dissipation fin group 2621 includes a plurality of fins arranged in parallel, which increases the contact area between the heat sink 26 and the air in the first heat dissipation sub-duct, thereby improving the heat dissipation efficiency. An air duct is formed between every two adjacent fins, and the air inlet of the air duct is opposite to the air outlet 252 of the fan, which facilitates the entry of air into the air duct, increases the contact speed between the air and the heat sink, and further improves the heat dissipation efficiency.

[0066] Among them, the second heat dissipation fin group 2622 includes multiple parallel fins, and the fins in the second heat dissipation fin group 2622 extend from the bottom of the support member to the bottom of the shell 1 to increase the heat dissipation area of ​​the heat dissipation member 26, fully utilize the internal space of the hair removal device, and improve the heat dissipation efficiency.

[0067] It can be seen that in this example, the first heat dissipation fin group 2621 and the second heat dissipation fin group 2622 of the heat dissipation end 262 of the heat dissipation element increase the heat dissipation area of ​​the heat dissipation element 26, improve the heat dissipation efficiency, and the first heat dissipation fin group 2621 and the second heat dissipation fin group 2622 are located in different heat dissipation sub-ducts to avoid the dissipated heat affecting each other, thereby further improving the heat dissipation efficiency.

[0068] In a possible example, the air outlet 252 of the fan is connected to the air inlets of the first heat dissipation sub-duct and the second heat dissipation sub-duct, and the air outlets of the first heat dissipation sub-duct are communicated with the air outlets of the second heat dissipation sub-duct.

[0069] For a specific example, see Figure 8 The heat dissipation end 262 of the heat dissipation element divides the first heat dissipation duct 27 into a first heat dissipation sub-duct and a second heat dissipation sub-duct. The air inlets of the first heat dissipation sub-duct and the second heat dissipation sub-duct are connected to the air outlet 252 of the fan, and the air outlets of the first heat dissipation sub-duct and the second heat dissipation sub-duct are connected to each other, so as to increase the air flow rate in the first heat dissipation sub-duct and the second heat dissipation sub-duct, thereby improving the heat dissipation efficiency.

[0070] In one possible example, see again Figure 5 and Figure 8 The support member also includes a fan mounting seat 29, and the fan 25 is arranged on the fan mounting seat 29; the air inlet 251 of the fan is connected to at least one air inlet opened on the shell 1, so that air can be introduced from the air inlet of the shell 1 to the air inlet 251 of the fan.

[0071] In a specific example, the support member includes a fan mounting seat 29, and the fan 25 is fixedly arranged on the fan mounting seat 29, and the fan mounting seat 29 is provided with an air inlet hole connecting the inner cavity of the shell 1 and the air inlet 251 of the fan, so that the air inlet of the shell 1, the inner cavity of the shell 1 and the air inlet 251 of the fan are connected to form an air inlet channel to ensure heat dissipation.

[0072] Among them, at least one air inlet is opened on the housing 1, please refer to Figure 2 、 Figure 5 and Figure 8, at least one air inlet includes a first air inlet 121 and a second air inlet 122. The first air inlet 121 is opposite to the air inlet 251 of the fan, so that the fan 25 can inhale air. The second air inlet 122 is located at the tail end of the shell 1, so that when the fan 25 inhales air, the air flow rate between the tail end of the shell 1 and the fan 25 is accelerated, thereby reducing the heat of the components between the tail end of the shell 1 and the fan 25. Specifically, a part of the control module 3 is arranged between the support and the upper shell 11, and the other part of the control module 3 is arranged between the tail end of the shell 1 and the fan 25, so as to reduce the temperature of the control module 3 and increase the service life of the equipment. It can be understood that the number of air inlets in the shell 1 can be set according to actual needs and is not limited here.

[0073] It can be seen that in this example, the housing 1 is provided with at least one air inlet, which is connected to the air inlet 251 of the fan to improve the heat dissipation efficiency.

[0074] In one possible example, see Figures 9-11 , Figure 9 This is a schematic diagram of an assembly of a heat sink provided in an embodiment of the present application, mounted on a lower support frame; Figure 10 This is a structural diagram of an upper support frame provided in an embodiment of the present application; Figure 11 This embodiment of the present application provides Figure 9 Schematic diagram of the cross section at BB.

The channel wall and the third channel wall are combined to form the third channel wall, and the third channel wall is formed by the combination of the fifth heat dissipation channel baffle 213 in the upper support frame 21 and the sixth heat dissipation channel baffle 223 in the lower support frame 22; the first channel wall and the fourth channel wall constitute the heat dissipation outlet channel 2010, and the fourth channel wall is formed by the combination of the seventh heat dissipation channel baffle 214 in the upper support frame 21 and the eighth heat dissipation channel baffle 224 in the lower support frame 22; the second channel wall divides the heat dissipation space in the support member into the first heat dissipation air inlet channel and the second heat dissipation air inlet channel; the first heat dissipation air duct 27 and the second heat dissipation air duct 28 share the heat dissipation outlet channel 2010, and the heat dissipation outlet channel 2010 is connected to the shell air outlet 111 opened on the shell 1.

[0075] In this specific example, the support member includes an upper support frame 21 and a lower support frame 22. The upper support frame 21 and the lower support frame 22 are combined to form the support member. During installation, the upper support frame 21 is positioned adjacent to one end of the upper housing 11, while the lower support frame 22 is positioned adjacent to one end of the lower housing 12. The upper support frame 21 includes a first heat dissipation channel baffle 211, a third heat dissipation channel baffle 212, a fifth heat dissipation channel baffle 213, and a seventh heat dissipation channel baffle 214. The lower support frame 22 includes a second heat dissipation channel baffle 221, a fourth heat dissipation channel baffle 222, a sixth heat dissipation channel baffle 223, and an eighth heat dissipation channel baffle 224. When the upper support frame 21 is combined with the lower support frame 22, the first heat dissipation channel baffle 211 and the second heat dissipation channel baffle 221 form a first channel wall, the third heat dissipation channel baffle 212 and the fourth heat dissipation channel baffle 222 form a second channel wall, the fifth heat dissipation channel baffle 213 and the sixth heat dissipation channel baffle 223 form a third channel wall, and the seventh heat dissipation channel baffle 214 and the eighth heat dissipation channel baffle 224 form a fourth channel wall. Among them, the first channel wall and the second channel wall enclose the first heat dissipation air inlet channel, the second channel wall and the third channel wall enclose the second heat dissipation air inlet channel, and the fourth channel wall and the first channel wall enclose the heat dissipation air outlet channel 2010. The first heat dissipation air duct 27 is composed of the first heat dissipation air inlet channel and the heat dissipation air outlet channel 2010, and the second heat dissipation air duct 28 is composed of the second heat dissipation air inlet channel and the heat dissipation air outlet channel 2010, that is, the first heat dissipation air duct 27 and the second heat dissipation air duct 28 share the heat dissipation air outlet channel 2010. Please combine Figure 2 The shell 1 is provided with a shell air outlet 111, which is connected to the heat dissipation outlet channel 2010, so that the air carrying heat can be quickly discharged from the hair removal device.

[0076] As can be seen, in this example, multiple heat dissipation ducts are formed in the support member to improve heat dissipation efficiency. In addition, the support member is formed by combining the upper support frame 21 and the lower support frame 22 to improve installation efficiency.

[0077] In one possible example, see again Figure 9 and Figure 10The second heat dissipation channel baffle 221 is provided with a first protruding strip, and the first heat dissipation channel baffle 211 is provided with a first groove that cooperates with the first protruding strip. When the first protruding strip is engaged with the first groove, the first heat dissipation channel baffle 211 and the second heat dissipation channel baffle 221 form the first channel wall; the fourth heat dissipation channel baffle 222 is provided with a second protruding strip, and the third heat dissipation channel baffle 212 is provided with a second groove that cooperates with the second protruding strip. When the second protruding strip is engaged with the second groove, the third heat dissipation channel baffle 212 and the fourth heat dissipation channel baffle 222 form the second channel wall ; The sixth heat dissipation channel baffle 223 is provided with a third protruding strip, and the fifth heat dissipation channel baffle 213 is provided with a third groove that cooperates with the third protruding strip. When the third protruding strip is engaged with the third groove, the fifth heat dissipation channel baffle 213 and the sixth heat dissipation channel baffle 223 form the third channel wall; the eighth heat dissipation channel baffle 224 is provided with a fourth protruding strip, and the seventh heat dissipation channel baffle 214 is provided with a fourth groove that cooperates with the fourth protruding strip. When the fourth protruding strip is engaged with the fourth groove, the seventh heat dissipation channel baffle 214 and the eighth heat dissipation channel baffle 224 form the fourth channel wall.

[0078] In a specific example, when the first heat dissipation channel baffle 211 and the second heat dissipation channel baffle 221 form a first channel wall, the first protrusion of the second heat dissipation channel baffle 221 cooperates with the first groove on the first heat dissipation channel baffle 211 to improve the sealing performance of the first channel wall.

[0079] When the third heat dissipating channel baffle 212 and the fourth heat dissipating channel baffle 222 form the second channel wall, the second protruding strip on the fourth heat dissipating channel baffle 222 cooperates with the second groove on the third heat dissipating channel baffle 212 to improve the sealing performance of the second channel wall.

[0080] When the fifth heat dissipation channel baffle 213 and the sixth heat dissipation channel baffle 223 form the third channel wall, the third protrusion on the sixth heat dissipation channel baffle 223 cooperates with the third groove on the fifth heat dissipation channel baffle 213 to improve the sealing performance of the third channel wall.

[0081] When the seventh heat dissipation channel baffle 214 and the eighth heat dissipation channel baffle 224 form the fourth heat dissipation channel wall, the fourth protrusion on the eighth heat dissipation channel baffle 224 cooperates with the fourth groove on the seventh heat dissipation channel baffle 214 to improve the sealing performance of the fourth heat dissipation channel wall. It is understood that the protrusions can also be provided on the heat dissipation channel baffles of the upper support frame 21, and the matching grooves can be provided on the heat dissipation channel baffles of the lower support frame 22, without limitation here.

[0082] It can be seen that in this example, when the air duct baffle on the upper support frame 21 is combined with the air duct baffle on the lower support frame 22, a double-stop multiple sealing setting is performed at the combination to improve the sealing of the channel wall and thereby improve the sealing of the heat dissipation air duct.

[0083] In an embodiment of the present application, a hair removal device is also included, which includes the heat dissipation component 2 as described above, wherein the hair removal device also includes a hair removal component 4, and the hair removal component 4 includes a reflective cup, a lamp tube, a filter plate and a mirror cover; the reflective cup, the lamp tube, the filter plate and the mirror cover are arranged in the second heat dissipation duct 28 of the heat dissipation component, and are arranged in sequence along the inner cavity of the second heat dissipation duct 28 toward the light outlet.

[0084] In the specific example, please combine Figure 2 and Figure 8 .like Figure 2 and Figure 8 As shown, the hair removal assembly 4 includes a housing 1, a heat dissipation assembly 2, a control module 3, and the hair removal assembly 4. The housing 1 includes an upper housing 11, a lower housing 12, and a head cover 13. The upper housing 11 and the lower housing 12 are arc-shaped housings, so that the partial housing formed by the upper housing 11 and the lower housing 12 is arc-shaped, which makes it easier for the user to grasp the hair removal device and improves the user experience. The head cover 13 is snapped onto the front end of the partial housing combined with the upper housing 11 and the lower housing 12, and is provided with a light-emitting hole that penetrates the inner cavity of the housing 1.

[0085] The heat dissipation component 2 is arranged at the front end of the inner cavity of the shell 1, and the light outlet of the heat dissipation component 2 is connected to the light outlet hole of the shell 1. The heat dissipation component 2 includes a support member, a cold compress 23, a refrigeration member 24, a heat dissipation member 26 and a fan 25. The support member includes an upper support frame 21 and a lower support frame 22. The upper support frame 21 and the lower support frame 22 are combined to form a support member, and when installed in the inner cavity of the shell 1, the upper support frame 21 is arranged near one end of the upper shell 11, and the lower support frame 22 is arranged near one end of the lower shell 12. It can be understood that the installation position of the support member can be set according to actual needs and is not limited here.

[0086] At least one heat dissipation duct is provided in the support member, for example, Figure 9 and Figure 10, may include a first heat dissipation duct 27 and a second heat dissipation duct 28, the air inlet of the first heat dissipation duct 27 and the air inlet of the second heat dissipation duct 28 are respectively connected to the air outlet 252 of the fan, and the air outlet of the first heat dissipation duct 27 and the air outlet of the second heat dissipation duct 28 are respectively connected to the air outlet 111 of the shell. It can be understood that the number of heat dissipation ducts can be set according to actual needs and is not limited here. Specifically, the support member includes a first channel wall, a second channel wall, a third channel wall and a fourth channel wall, the first channel wall and the second channel wall constitute a first heat dissipation air inlet channel, the second channel wall and the third channel wall constitute a second heat dissipation air inlet channel, and the fourth channel wall and the first channel wall constitute a heat dissipation air outlet channel 2010. The first heat dissipation duct 27 is composed of the first heat dissipation air inlet channel and the heat dissipation air outlet channel 2010, and the second heat dissipation duct 28 is composed of the second heat dissipation air inlet channel and the heat dissipation air outlet channel 2010. The second heat dissipation duct 28 is located on the side of the support member close to the front end of the shell 1. The third channel wall of the second heat dissipation duct 28 faces the light-emitting hole of the shell 1. A light outlet is opened on the third channel wall, and the light outlet is connected to the light-emitting hole of the shell 1.

[0087] The inner side of the cold compress 23 is set on the outer wall of the end of the support where the light outlet is located, and the outer side of the cold compress 23 abuts the inner wall of the shell 1. The cold compress 23 is flush with the plane where the light outlet hole of the shell 1 is located, so that when the user uses the hair removal device, the cold compress 23 contacts the user's skin to provide a cold compress.

[0088] The cooling end of the cooling element 24 abuts against the cooling element 23 , and the heat dissipation end of the cooling element 24 abuts against the heat dissipation element 26 , so as to transfer the heat of the cooling element 24 to the heat dissipation element 26 .

[0089] The heat sink's connection end 261 is located on the outer wall of the support's bottom. A through hole is also provided at the support's bottom, connecting the inner cavity of the housing 1 with the first heat dissipation channel. The heat sink's heat dissipation end 262 is inserted through this through hole into the support's first heat dissipation duct 27, dividing the first heat dissipation duct 27 into a first heat dissipation sub-duct and a second heat dissipation sub-duct. A channel baffle is provided around the through hole. This channel baffle extends from the outer wall of the support's bottom toward the inner wall of the lower housing 12 and abuts against the inner wall of the lower housing 12, so that the channel baffle, the lower support frame 22, and a portion of the housing 1 form a first cavity. The first heat dissipation duct 27 connects to this first cavity, increasing the space in the first heat dissipation duct 27 to accommodate a larger heat sink 26, thereby improving heat dissipation efficiency. Furthermore, the channel baffle forms an independent channel between the first heat dissipation duct 27's air inlet and outlet, isolated from the rest of the housing 1's inner cavity, preventing heat from the first heat dissipation duct 27 from diffusing into other cavities within the housing 1. The heat dissipation end 262 of the heat sink is provided with a first heat dissipation fin group 2621 and a second heat dissipation fin group 2622. The first heat dissipation fin group 2621 is located in the first heat dissipation sub-duct, and the second heat dissipation fin group 2622 is located in the second heat dissipation sub-duct to increase the heat dissipation area of ​​the heat sink and improve the heat dissipation efficiency.

[0090] The fan 25 is mounted on a fan mounting base 29 of the support member. Its air inlet 251 faces the first air inlet 121 of the housing 1. The housing 1 also includes a second air inlet 122 located at the rear end of the housing 1. An air inlet channel is formed between the first and second air inlets 121, 122, part of the inner cavity of the housing 1, and the fan's air inlet 251. This improves air intake efficiency while also drawing heat away from the channel to reduce internal heat within the hair removal device.

[0091] One end of the control module 3 is arranged between the upper support frame 21 and the upper shell 11, and the other end of the control module 3 is arranged in the air inlet channel, so that when the fan 25 takes in air, it takes away the heat of the capacitors, chips and other components of the control module 3, thereby reducing the overall temperature of the hair removal device.

[0092] The hair removal component 4 includes a reflective cup, a lamp, a filter plate and a mirror cover. The reflective cup, the lamp, the filter plate and the mirror cover are arranged in the second heat dissipation duct 28 and arranged in sequence along the inner cavity of the second heat dissipation duct 28 towards the light outlet. Figure 8 A mounting groove is provided on the inner wall of the second heat dissipation duct 28 at one end near the light outlet. The reflective cup is a U-shaped cup. The cup mouth of the U-shaped cup is engaged in the mounting groove. The filter plate is also engaged in the mounting groove. The lamp tube is arranged in the accommodating channel formed between the U-shaped cup and the filter plate. The mirror cover is arranged on the inner wall of the light outlet to converge light and improve the light output rate.

[0093] The heat dissipation path of the heat dissipation duct is as follows: air is drawn in by the fan 25 from the air inlet duct and then delivered to the first heat dissipation duct 27 and the second heat dissipation duct 28. The air entering the first heat dissipation duct 27 is blown toward the first and second heat dissipation sub-ducts, removing heat from the first heat dissipation fin group 2621 in the first heat dissipation sub-duct and the second heat dissipation fin group 2622 in the second heat dissipation sub-duct. The air is then blown from the heat dissipation outlet 2010 of the first heat dissipation duct 27 toward the housing air outlet 111, thereby discharging the heat out of the hair removal device. The air entering the second heat dissipation duct 28 removes heat from the reflector cup, the lamp, and other components of the hair removal assembly 4 located in the second heat dissipation duct 28. The air is then blown from the heat dissipation outlet 2010 of the second heat dissipation duct 28 toward the housing air outlet 111, thereby discharging the heat out of the hair removal device.

[0094] It can be seen that in this example, a plurality of heat dissipation ducts are provided in the support member of the heat dissipation component 2 to improve the heat dissipation efficiency, and the first heat dissipation duct 27 is divided into a first heat dissipation sub-duct and a second heat dissipation sub-duct by the heat dissipation member 26. A heat dissipation fin group is provided at the heat dissipation end 262 of the heat dissipation member, and the heat dissipation fin groups are respectively placed in different heat dissipation sub-ducts to increase the heat dissipation area of ​​the heat dissipation member 26 and further improve the heat dissipation efficiency.
