This method destroys the hair follicle and can achieve long-term depilation effect if used consistently.

[0047] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0049] In addition, the descriptions involving “first”, “second” and the like in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined with “first”, “second” can explicitly or implicitly include the features.

[0050] In the present application, unless otherwise explicitly specified and limited, the terms “connection”, “fixation” and the like should be understood in a broad sense, for example, “fixation” can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be direct connection, or indirect connection through intermediate medium; can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise explicitly limited.

[0051] Reference Figures 1-6This invention provides a hair removal device 1000, which includes a housing 200. A light source assembly 300 is disposed within the housing 200. The light source assembly 300 includes a light source shell 310, a light source 320 housed within the light source shell 310, and a reflector 330. The light source shell 310 has a light emission window 3106. The light source 320 generates high-intensity laser light under the action of an electric current. The reflector 330 is disposed on the side of the light source 320 away from the light emission window 3106, and is used to reflect the laser light emitted by the light source 320 back to the light emission window 3106 for emission, thereby burning human skin hair to achieve hair removal. Meanwhile, to ensure light intensity, the reflector 330 is constructed in a U-shape, and the light source 320 adopts the form of a lamp tube. When the light source 320 is working, some light is emitted directly from the light-emitting window 3106. The light that shines on the inner arc surface of the U-shaped reflector 330 is concentrated and emitted from the light-emitting window 3106, effectively improving the light intensity.

[0052] To prevent the human body from touching the light source 320 through the light outlet window 3106, and to prevent external dust from entering the light source assembly 300 and causing a burning odor, such as Figure 2 As shown, in this embodiment of the invention, a light-transmitting crystal 400 is installed in the light-emitting window 3106. The light-transmitting crystal 400 is made of a high-temperature resistant material, such as glass or gemstone, which have good light transmission. In this solution, sapphire crystal is preferred. By constructing the sapphire crystal to match the shape of the light-emitting window 3106 and installing it in the light-emitting window 3106, it is at least partially located in the light path of the light emitted by the light source assembly 300, thereby guiding light and preventing external substances from entering the light source assembly 300 from the light-emitting window 3106.

[0053] like Figure 2 As shown, in this embodiment of the invention, another portion of the sapphire is exposed from the outer casing 200 for contact with human skin. Simultaneously, to reduce the burning sensation on human skin caused by the high-intensity light emitted from the sapphire, the hair removal device 1000 in this technical solution also includes a cooling component 100 to cool the sapphire, thereby forming a cooling area 410 on the sapphire surface exposed from the outer casing 200.

[0054] like Figure 4As shown, in the embodiment of the present application, specifically, the cold compress assembly 100 includes a semiconductor refrigeration sheet 10 and a heat dissipation fan 30. After the semiconductor refrigeration sheet 10 is powered on, the electronic negative (-) electrode starts, first passes through the P-type semiconductor, absorbs heat here, and then releases heat to the N-type semiconductor. Every time a NP module is passed, heat is sent to one side to cause a temperature difference, so that the two surfaces of the semiconductor refrigeration sheet 10 form a heating surface and a cooling surface. The cooling surface is in contact with one side wall of the light-transmitting crystal 400, and is used to cool the light-transmitting crystal 400. It can be understood that in order to improve the cooling effect, the semiconductor refrigeration sheet 10 can be installed on the side wall with a larger surface area of the light-transmitting crystal 400. At the same time, the semiconductor refrigeration sheet 10 and the light-transmitting crystal 400 are directly coated with heat-conducting silicone to ensure close fitting and improve heat conduction performance. Similarly, the heating end of the semiconductor refrigeration sheet 10 and the heat dissipation frame 50 are also coated with heat-conducting silicone to ensure rapid heat conduction between the two.

[0055] It can be understood that in actual application, the cold compress area 410 is not limited to the part of the surface of the sapphire extending out of the outer shell 200 for contacting the human skin in the above-mentioned embodiment. For example, in other embodiments of the present application, a mounting gap (not shown) can be provided on the outer shell 200 around the light rays to open the light-emitting window 3106, and a cold compress cover (not shown) with high heat conduction performance is installed. One side of the cold compress cover extends into the inner part of the outer shell 200. The other side is exposed to the outer shell 200 for contacting the user's skin to form the cold compress area 410. This method also belongs to the protection scope of the present application.

[0056] Further, since the temperature of the sapphire is low in the state of cooling the refrigeration surface of the semiconductor refrigeration sheet 10, water mist condensation is easily generated when it is in contact with external hot air flow. Therefore, as shown, Figure 2 In the present technical solution, the outer shell 200 is also provided with a flexible pad 800, which covers the surface of the sapphire exposed to the outside and is provided with a light-transmitting area corresponding to the light-transmitting area. The flexible pad 800 can be made of transparent silicone material to prevent the direct contact between the outside air and the sapphire, thereby avoiding the generation of condensed water mist. Thus, the light deviation caused by the condensed water and air mist is avoided.

[0057] To facilitate the installation of the flexible pad 800, a portion of the flexible pad body that avoids the light-transmitting area is also provided with connecting protrusions 810. For example, the flexible pads 800 located on both sides of the cold compress area are provided with connecting protrusions 810. The outer shell 200 is provided with corresponding connecting blind holes (not shown). Two connecting protrusions 810 are inserted into two connecting blind holes to fix the flexible pad 800 to the outer shell 200. The connecting blind holes in the outer shell 200 effectively prevent internal light from escaping, while the connecting protrusions 810 on the flexible pad 800 enhance its strength and prevent the flexible pad 800 from detaching from the outer shell 200.

[0058] It is understood that in practical applications, the method is not limited to the above embodiment where the flexible pad 800 has a connecting protrusion 810 and the outer shell 200 has a connecting blind hole. For example, in other embodiments of the present invention, adhesive can also be used, or the flexible pad 800 can have a connecting blind hole and the outer shell 200 can have a connecting protrusion, or the outer periphery of the flexible pad 800 can be extended along the shape of the outer shell to form a sleeve and fitted onto the end of the outer shell 200 that emits light to achieve installation. All of these methods are within the protection scope of the present invention.

[0059] like Figure 1 As shown in the embodiment of the present invention, specifically, the surface of the outer shell 200 is provided with an air inlet 210 and an air outlet 220. Driven by current, the cooling fan 30 draws external airflow into the interior of the outer shell 200 through the air inlet 210 and then discharges it through the air outlet 220. The air inlet 210 and the air outlet 220 are constructed by multiple small-diameter through holes on the surface of the outer shell 200, which effectively prevents external objects from being drawn into the interior of the outer shell 200 and causing damage to the internal components.

[0060] like Figure 5 As shown in the embodiment of the invention, the heat sink 50 is specifically made of a metal material with high thermal conductivity, such as copper, aluminum, or a copper-aluminum alloy. In this technical solution, aluminum is preferred for cost saving. The heat sink 50 includes three integrally formed parts 53: the first part 51 is constructed into a plate shape, and the area of ​​the first part 51 is larger than the area of ​​the side wall corresponding to the light-transmitting crystal 400, thus fully covering the side wall corresponding to the light-transmitting crystal 400 to achieve maximum heat conduction area. Simultaneously, heat conduction is achieved through heat-dissipating silicone. The second part 52 contacts the outer wall of the light source assembly 300, and the third part 53 is located in the airflow path of the cooling fan 30. When the heat from the first part 51 and the second part 52 is rapidly conducted to the third part 53, the heat from the third part 53 is quickly transferred away by the airflow generated when the cooling fan 30 is working, preventing heat concentration.

[0061] Specifically, the number of semiconductor cooling chips 10 can also be two. The cooling surfaces of both semiconductor cooling chips 10 are in contact with the sidewall of the light-transmitting crystal 400. They can be the same sidewall, two adjacent sidewalls, or two opposite sidewalls. Again, without further limitation, the method of extending an additional part (not shown) from any part of the first, second, or third part of the heat sink 50 to contact another semiconductor cooling chip (not shown) to achieve heat conduction and enhance the cooling effect is also within the scope of protection of this invention.

[0062] like Figure 5 As shown in this embodiment of the invention, specifically, the third part 53 is constructed into a frame 531, and a plurality of spaced heat dissipation plates 532 are constructed in the hollow part of the frame 531. The first sidewall of the frame 531 is connected to the second part 52. Because the third part 53 needs to be constructed to a larger size to enhance the heat dissipation surface area, in order to prevent the second and third sidewalls connected to both ends of the first sidewall from being too thin and thus easily deformed during processing, the two ends of the plurality of heat dissipation plates 532 are respectively connected to the second and third sidewalls of the frame 531 and constructed to be parallel to the first sidewall, effectively enhancing the connection strength. At the same time, the plurality of heat dissipation plates 532 effectively increase the heat dissipation surface area and improve the heat dissipation efficiency.

[0063] It is understood that in practical applications, the third part 53 is not limited to the heat sink 532 and the frame 531 being integrally parallel. For example, in other embodiments of this technical solution, the third part 53 can also be constructed as a grille or mesh, with the open spaces of the grille or mesh forming airflow channels for airflow. Increasing the heat dissipation surface area also falls within the scope of this invention. Further details will not be elaborated here.

[0064] To effectively utilize the cooling fan's 30mm airflow and reduce its footprint, such as Figure 1 , Figure 2 or Figure 4As shown, in the embodiment of the present application, the third part 53 is located between the suction end 31 of the heat dissipation fan 30 and the air inlet 210, and when the heat dissipation fan 30 works, the external airflow enters the suction end 31 of the heat dissipation fan 30 after being blown away and cooled by the air inlet 210. At the same time, in order to facilitate installation, the frame 531 of the third part 53 is fixed to the surface of the suction end 31 of the heat dissipation fan 30 by the locking piece 500, so that the frame 531 is tightly attached to the suction end 31 of the heat dissipation fan 30, so that the hollow part of the frame 531 is constructed into a gas guide cavity in gas path communication with the suction port 311 of the suction end 31. At the same time, a plurality of heat dissipation plates 532 are located in the gas guide cavity and are arranged on the suction port 311 of the heat dissipation fan 30, so as to ensure that the airflow sucked by the heat dissipation fan 30 is blown away and cooled at high speed by the plurality of heat dissipation plates 532. Compared with the traditional depilation instrument 1000 scheme, the heat dissipation structure is installed downstream of the airflow of the heat dissipation fan 30, and the heat dissipation fan 30 and the heat dissipation assembly are connected by constructing a gas guide pipeline. The technical scheme does not need to conduct the airflow through a long gas guide pipeline, which causes wind energy loss. The plurality of through holes of the air inlet 210 are arranged to realize high-speed airflow impact, which further improves the heat dissipation efficiency. The locking piece 500 can adopt one or more of screws, buckles, connecting pins and the like. In order to prevent the third part 53 and the heat dissipation fan 30 from being loosened due to the slight vibration of the heat dissipation fan 30 during work, the locking piece 500 adopts a screw to lock the third part 53 to the heat dissipation fan 30. At the same time, by tightening the screwing force of the locking piece 500, the third part 53 can be effectively pressed to the heat dissipation fan 30.

[0065] At the same time, as Figure 1 Combined with Figure 2 As shown, in the embodiment of the present application, the surface of the frame 531 away from the heat dissipation fan 30 is also provided with a sealing ring 70, and the two side surfaces of the sealing ring 70 are respectively sealed in the inner wall of the frame 531 and the outer shell 200 provided with the air inlet 210, so that the inner ring surface of the sealing ring 70 is constructed into the only gas path connecting the air inlet 210 and the gas guide cavity. The sealing ring 70 can be made of a material with elastic properties, such as silicone, rubber, etc., so as to ensure the sealing effect of the gas path.

[0066] Further, as Figure 1 Combined with Figure 2As shown in the embodiment of the present application, the light source shell 310 is further provided with an air inlet window 3101 and an air outlet window 3102, and a heat dissipation channel 3103 is formed between the air inlet window 3101 and the air outlet window 3102, which is connected to the light source 320 and the reflector 330 in the light source shell 310. The air flow discharged from the air outlet end 32 of the heat dissipation fan 30 flows into the heat dissipation channel 3103 through the air inlet window 3101, and carries away the heat generated by the light source 320 and the reflector 330 when passing through the light source 320 and the reflector 330, and is then discharged through the air outlet window 3102.

[0067] Further, as Figure 1 shown in the embodiment of the present application, the air outlet window 3102 is opposite to the air outlet 220 of the outer shell 200, thereby preventing the hot air discharged from the air outlet window 3102 from gathering in the outer shell 200 to cause a safety hazard of heat concentration, and preventing the light emitted by the light source 320 from being emitted from the air outlet window 3102 to cause harm to the outside. In order to prevent the above-mentioned phenomenon, the light source 320 is located in the U-shaped cavity of the U-shaped reflector 330, and the outer wall of the arc surface of the reflector 330 is spaced apart from the inner wall of the light source shell 310 to form the heat dissipation channel 3103, thereby effectively preventing the above-mentioned phenomenon.

[0068] At the same time, as Figures 1-4 shown in the embodiment of the present application, in order to further save installation space, the air outlet end 32 of the heat dissipation fan 30 is inserted into the air inlet window 3101 without the need for connection through a gas guide pipe. This makes the internal cavity of the outer shell 200 have a large space for arrangement from the light source assembly 300 to the heat dissipation fan 30, and thus a larger capacitor can be installed, thereby realizing high-power output. Meanwhile, the built-in battery 700 is installed on the side of the heat dissipation fan 30 away from the light source assembly 300, which is used to supply power to the light source assembly 300 and the cold compress assembly 100, so as to realize on-body use without the need for external power cable, thereby enhancing the applicable scenarios of the product.

[0069] Specifically, as Figure 1 , Figure 3 in combination Figure 5As shown, in this embodiment of the invention, the second part 52 is constructed as a rectangular frame 521. The frame 521 is fixed to the light source housing 310 using a locking member 500, such as screws, to ensure close contact between the frame 521 and the light source housing 310. Simultaneously, the two side walls of the frame 521 are connected to the first part 51 and the third part 53, respectively. A plurality of heat sinks 522 are constructed in the hollow portion of the frame 521, with the heat sinks 522 spaced apart in the hollow portion of the frame 521. Since the air outlet 32 ​​of the cooling fan 30 is directly plugged into the air inlet window 3101 of the light source housing 310, the second part 52 is smaller in size than the third part 53 and has a high connection strength. To ensure that the heat of the first part 51 is quickly conducted, multiple heat sinks 522 are spaced apart in the hollow part of the frame 521, and their two ends are respectively connected to the side wall of the frame 521 facing the first part 51 and the side wall of the frame 521 facing the third part 53, so that multiple heat conduction paths are established between the first part 51 and the third part 53 through multiple heat dissipation edges, thereby greatly improving the heat dissipation efficiency of the first part 51.

[0070] It is understood that in actual use, the second part 52 is not limited to the rectangular frame 521 used in the above embodiments. For example, it can also be circular, rhomboid, triangular, etc., all of which are within the scope of protection of this invention, and will not be elaborated further.

[0071] Furthermore, such as Figure 6 As shown, in this embodiment of the invention, in order to accelerate the heat dissipation efficiency of the second part 52, for ease of description, the surface of the second part 52 attached to the light source housing 310 is defined as the first surface 3104; in this technical solution, a portion of the air inlet window 3101 is exposed from the first surface 3104, forming an air guide notch 3105, and the airflow discharged from the air outlet 32 ​​of the cooling fan 30 flows at least partly from the air guide notch 3105 to the second part 52, blowing and cooling the second part 52.

[0072] Specifically, such as Figure 5 As shown, in this embodiment of the invention, the side wall of the frame 521 connected to the third part 53 is higher than the heat sink 522. Therefore, the height difference between the side wall and the heat sink 522 forms an airflow passage 523. At the same time, the side wall of the frame 521 near the air guide notch 3105 is also provided with an air vent to connect with the airflow passage 523. Thus, the airflow discharged from the air inlet window 3101 blows onto each heat sink 522 through the air guide notch 3105 and the airflow passage 523, further improving the heat dissipation efficiency.

[0073] Specifically, as shown in 5, in the embodiment of the present application, the side wall of the frame 521 connected with the third part 53 is also provided with a gas guide groove 5211 to connect the gas flow in the hollow of the frame 521 to the hollow of the frame body 531 of the third part 53. When the cooling fan 30 is running, the suction force generated at the air inlet end can flow to the third part 53 through the gas guide groove 5211 and be sucked into the cooling fan 30 from the air inlet end.

[0074] Specifically, as shown in Figure 5 In the embodiment of the present application, the gas guide groove 5211 is arranged opposite to the connection between the heat dissipation plate 532 and the frame body 531, and a plurality of heat dissipation plates 532 are provided with a gas passing groove 5321 connected with the gas guide groove 5211, so that the gas flow extracted from the gas guide groove 5211 can blow and dissipate heat on the plurality of heat dissipation plates 532 along the gas passing groove 5321. At the same time, the connection between the frame body 531 and the heat dissipation plate 532 is provided, which effectively makes the heat dissipation plate 532 arranged on the edge of the cooling fan 30 be blown by the gas flow, preventing the phenomenon of heat concentration.

[0075] Further, as shown in Figure 1 In combination with Figure 2 In the embodiment of the present application, the gas flow is prevented from gathering in the second part 52, and the outer shell 200 is also provided with an auxiliary exhaust port 230, which is composed of a plurality of small holes, so that the gas flow in the second part 52 can be discharged through the auxiliary exhaust port 230.

[0076] Further, as shown in Figure 1 In combination with Figure 3 In the embodiment of the present application, in order to prevent the internal heat of the hair removal instrument 1000 from concentrating and ensure the stable work of the hair removal instrument 1000, the heat dissipation frame 50 further includes a fourth part 54, which is located on the side of the third part 53 away from the third part 53 and extends to cover the surface of the transformer device 600 in the outer shell 200, effectively transferring the heat of the transformer device 600 to the third part 53, preventing the phenomenon of unstable work caused by heat concentration of the transformer device 600.

[0077] Specifically, in the embodiment of the present application, the transformer device 600 and the cooling fan 30 are installed on the same side of the circuit board (not labeled), thereby saving installation space, and the height of the transformer device 600 is lower than the height of the cooling fan 30, avoiding the situation that the transformer device 600 is too high to contact external components and cause short circuit. Meanwhile, the fourth part 54 is constructed in a plate shape, and the inclined plate 55 is used to connect the fourth part 54 and the frame 531 of the third part 53. Therefore, the fourth part 54 attached to the transformer device 600 and the inner wall of the shell 200 form a heat dissipation cavity 551, and the inclined plate 55 is arranged to make the space of the heat dissipation cavity 551 larger, thereby facilitating heat dissipation of the transformer device 600. Meanwhile, the side wall of the frame 531 connected with the fourth part 54 is also provided with a gas guiding gap 5322, and the inclined plate 55 is partially located at the bottom end of the gas guiding gap 5322. When the cooling fan 30 works, the airflow in the heat dissipation cavity 551 formed between the fourth part 54 and the inner wall of the shell 200 is sucked into the gas guiding cavity through the gas guiding gap 5322, thereby accelerating heat dissipation of the fourth part 54.

[0078] Meanwhile, in order to ensure that the fourth part 54 is tightly attached to the transformer device 600, heat dissipation silica gel (not shown) is coated between the fourth part 54 and the transformer device 600, thereby improving heat conduction and avoiding the situation that virtual position leads to low heat conduction efficiency. Meanwhile, a connecting column (not labeled) is arranged at the intersection of the inclined plate 55 and the third part 53, and is fixed and locked with the shell of the cooling fan 30, so as to press the fourth part 54 to the transformer device 600.

[0079] Meanwhile, the transformer device 600 is arranged close to the cooling fan 30 and is installed between the cooling fan 30 and the battery 700, thereby preventing the situation that a large size inclined plate 55 is used to connect the third part 53 and the fourth part 54 of the heat dissipation frame due to long distance, and occupying arrangement space. Meanwhile, the transformer device 600 is arranged close to the cooling fan 30, so that the heat concentration points are all located on the side facing the cooling fan 30. When the cooling fan 30 works, hot air is sucked into the cooling fan 30, and therefore the heat generated by the transformer device 600 will not be conducted to the direction of the battery 700, thereby effectively preventing the situation that the battery 700 works in a high temperature environment and causes safety hazard.

[0080] Further, the battery 700 and the transformer 600 can be separated by a heat insulation filler (not shown), thereby preventing heat concentration, and the heat insulation filler can be made of porous material, such as foam, without limitation here, so that when the cooling fan 30 works, the airflow in the space containing the battery 700 can flow, thereby accelerating heat dissipation.

[0081] In the embodiments of the present application, the present application also provides a depilating instrument 1000, which comprises an outer housing 200, a surface of which is provided with an air inlet 210 and an air outlet 220, and inside which is provided with: a light source assembly 300 for generating light for removing hair; a light-transmitting crystal 400, at least a part of which is located in the light path of the light emitted by the light source assembly 300, and at least another part of which is exposed from the outer housing 200 to form a cold compress area 410 for contacting the human skin; and the depilating instrument 1000 further comprises a cold compress assembly 100. The specific mounting structure of the cold compress assembly 100 is referred to the above-mentioned embodiments. Since the depilating instrument 1000 adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0082] The above-mentioned is only the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields under the inventive concept of the present application is included in the patent protection scope of the present application.
