Description

TECHNICAL FIELD

[0002] The laser depilator is a kind of depilation method which uses the heat energy emitted by laser to irradiate the skin, so that the black pigment on the hair absorbs the laser energy and is converted into heat energy, which penetrates into the hair follicle, so that the skin hair follicle is damaged to achieve the effect of depilation. This method destroys the hair follicle and can achieve long-term depilation effect if used consistently. However, since it uses heat energy for depilation, it may cause a certain degree of pain during use.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" can be explicitly or implicitly included in the features.

For a person skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] With reference to Figures 1-6 The present application provides a depilating instrument 1000, which comprises an outer shell 200, a light source assembly 300 arranged in the outer shell 200, the light source assembly 300 comprising a light source shell 310, a light source 320 and a reflector 330 arranged in the light source shell 310, the light source shell 310 being provided with a light exit window 3106, the light source 320 generating high-intensity laser light under the action of current, and the reflector 330 being arranged on the side of the light source 320 away from the light exit window 3106, for reflecting the laser light emitted by the light source 320 to the light exit window 3106 to burn the hair on the human skin and achieve the effect of depilation. At the same time, in order to ensure the intensity of the light, the reflector 330 is configured in a U shape, and the light source 320 adopts a lamp tube form, when the light source 320 works, part of the light directly exits from the light exit window 3106, the light on the inner arc surface of the U-shaped reflector 330 is collected and then exits from the light exit window 3106, effectively improving the intensity of the light.

[0050] In order to prevent the human body from touching the light source 320 from the light exit window 3106 and prevent foreign dust from entering the light source assembly 300 to cause burning odor, the light source 320 is arranged in the light source shell 310, and the light source shell 310 is provided with a cover 3102, which is arranged on the side of the light source 320 away from the light exit window 3106, for covering the light source 320 and preventing foreign dust from entering the light source 320. Figure 2As shown in the embodiment of the present application, the light-transmitting crystal 400 is installed on the light-emitting window 3106, which is made of high-temperature-resistant material, such as glass, gem, and other materials with good light-transmitting effect. In this embodiment, sapphire crystal is preferably used. The sapphire crystal is constructed to be consistent with the shape of the light-emitting window 3106 and is installed on the light-emitting window 3106, and at least partially located on the light path of the light emitted by the light source assembly 300, so as to realize light guiding and prevent external substances from entering the light source assembly 300 from the light-emitting window 3106.

[0051] As shown in the embodiment of the present application, Figure 2 As shown in the embodiment of the present application, another part of the sapphire is exposed from the outer shell 200 for contacting with the human skin. Meanwhile, in order to reduce the burning sensation of the high-intensity light emitted from the sapphire on the human skin, the hair removal device 1000 in this technical solution further comprises a cold compress assembly 100 for refrigerating the sapphire, so as to form a cold compress area 410 on the surface of the sapphire exposed from the outer shell 200.

[0052] As shown in the embodiment of the present application, Figure 4 As shown in the embodiment of the present application, specifically, the cold compress assembly 100 comprises a semiconductor refrigerating sheet 10 and a heat dissipation fan 30. After the semiconductor refrigerating sheet 10 is powered on, the electron negative (-) is first passed through the P-type semiconductor to absorb heat, and then the heat is released in the N-type semiconductor. After passing through each NP module, the heat is sent to one side to cause a temperature difference, so that the two surfaces of the semiconductor refrigerating 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 for refrigerating the light-transmitting crystal 400. It can be understood that, in order to improve the refrigeration effect, the semiconductor refrigerating sheet 10 can be installed on the side wall with a larger surface area of the light-transmitting crystal 400. Meanwhile, the semiconductor refrigerating sheet 10 and the light-transmitting crystal 400 are directly coated with heat-conducting silica gel to ensure close contact and improve the heat conduction performance. Similarly, the heating end of the semiconductor refrigerating sheet 10 and the heat dissipation frame 50 are also coated with heat-conducting silica gel to ensure rapid heat conduction between them.

[0053] 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 with the human skin as described in the above embodiment. For example, in other embodiments of the present application, a mounting gap (not shown) can be formed on the outer shell 200 around the light rays from the light-emitting window 3106, and a cold compress cover (not shown) with high heat conduction performance is installed, one side of which extends into the inner part of the outer shell 200. The other side is in contact with the cold end of the semiconductor refrigerating sheet 10, and the other side is exposed to the outer shell 200 for contacting with the user's skin to form the cold compress area 410, which also belongs to the protection scope of the present application.

[0054] Further, since the sapphire has a low temperature in the state of refrigeration of the refrigeration surface of the semiconductor refrigeration sheet 10, water mist condensation is easily generated when it is contacted with the external hot airflow. Thus, as shown in the figure, in the technical solution, the shell body 200 is further provided with a flexible pad 800, which covers the surface of the part of the sapphire exposed to the outside, and a light transmission area is correspondingly provided for light emission. The flexible pad 800 can be made of transparent silica gel material to prevent the direct contact between the outside and the sapphire, thereby avoiding the generation of condensed water mist. Thus, the situation that the light is deviated and weakened due to the condensed water and the airflow is avoided. Figure 2

[0055] In order to facilitate the installation of the flexible pad 800, the part of the flexible pad body avoiding the light transmission area is further provided with a connecting protruding column 810, for example, the flexible pad 800 on both sides of the cold compress area is provided with a connecting protruding column 810, and the shell body 200 is correspondingly provided with connecting blind holes (not marked), and the two connecting protruding columns 810 are inserted into the two connecting blind holes to fix the flexible pad 800 to the shell body 200. The shell body 200 is provided with connecting blind holes to effectively prevent the internal light from being emitted, and the flexible pad 800 is provided with a connecting protruding column 810 to strengthen the strength of the flexible pad 800. The phenomenon that the flexible pad 800 is separated from the shell body 200 is prevented.

[0056] It can be understood that, in the actual application process, it is not limited to the above-mentioned embodiment that the flexible pad 800 is provided with a connecting protruding column 810 and the shell body 200 is provided with a connecting blind hole. For example, in other embodiments of the present application, a glue can be used, or the flexible pad 800 can be provided with a connecting blind hole and the shell body 200 can be provided with a connecting protruding column, or the outer periphery of the flexible pad 800 can be extended to the shape of the shell body to form a sleeve, which is connected to the end of the shell body 200 for light emission to achieve the installation. The above-mentioned methods all belong to the protection scope of the present application.

[0057] As shown in the figure, in the embodiment of the present application, specifically, the shell body 200 is provided with an air inlet 210 and an air outlet 220 on the surface, and the cooling fan 30 is driven by the current to draw the external airflow into the shell body 200 through the air inlet 210 and then discharge it through the air outlet 220. The air inlet 210 and the air outlet 220 are constructed by a plurality of small-diameter through holes on the surface of the shell body 200, which effectively prevents the external objects from being drawn into the shell body 200 to damage the internal components. Figure 1 As shown in the figure, in the embodiment of the present application, specifically, the shell body 200 is provided with an air inlet 210 and an air outlet 220 on the surface, and the cooling fan 30 is driven by the current to draw the external airflow into the shell body 200 through the air inlet 210 and then discharge it through the air outlet 220. The air inlet 210 and the air outlet 220 are constructed by a plurality of small-diameter through holes on the surface of the shell body 200, which effectively prevents the external objects from being drawn into the shell body 200 to damage the internal components.

[0058] Figure 5 ​​As shown, in the embodiment of the present application, specifically, the heat dissipation frame 50 is made of metal material with high heat conduction efficiency, for example, copper, aluminum or copper-aluminum alloy, and in the present technical solution, aluminum is preferably used for cost saving. The heat dissipation frame 50 includes integrally formed first, second and third parts 53; the first part 51 is constructed in a plate shape, and the area of the first part 51 is larger than the area of the corresponding side wall of the light-transmitting crystal 400, so as to fully cover the corresponding side wall of the light-transmitting crystal 400, to achieve the maximum heat conduction area, and meanwhile, the heat is conducted through the heat dissipation silica gel. The second part 52 is in contact with the outer wall of the light source assembly 300, and the third part 53 is located on the air path of the heat dissipation fan 30. When the heat of the first part 51 and the second part 52 is rapidly conducted to the third part 53, and the heat of the third part 53 is rapidly transferred away by the airflow generated by the operation of the heat dissipation fan 30, the phenomenon of heat concentration is avoided.

[0059] Specifically, the number of the semiconductor refrigeration pieces 10 can also be two, and the refrigeration faces of the two semiconductor refrigeration pieces 10 are in contact with the side walls of the light-transmitting crystal 400, which can be the same side wall, two adjacent side walls or two opposite side walls. Again, without too many limitations, an additional part (not shown) is extended from any one of the first, second or third parts of the heat dissipation frame 50 to contact another semiconductor refrigeration piece (not shown) to achieve heat conduction and enhance the refrigeration effect, which also belongs to the protection scope of the present application.

[0060] As shown, Figure 5 In the embodiment of the present application, specifically, the third part 53 is constructed in a frame body 531 shape, and meanwhile, a plurality of heat dissipation plates 532 are arranged at intervals in the hollow of the frame body 531. The first side wall of the frame body 531 is connected with the second part 52, and since the third part 53 needs to be constructed in a larger size to enhance the heat dissipation surface area, in order to prevent the second and third side walls connected with the two ends of the first side wall from being too thin in wall thickness, causing the third part 53 to be easily deformed during processing, the two ends of the plurality of heat dissipation plates 532 are connected with the second and third side walls of the frame body 531 respectively, and are constructed to be arranged in parallel with the first side wall, effectively enhancing the connection strength. Meanwhile, the heat dissipation surface area is effectively increased by the plurality of heat dissipation plates 532, and the heat dissipation efficiency is improved.

[0061] It can be understood that in actual application process, the third part 53 is not limited to the above-mentioned heat dissipation plates 532 and frame body 531 arranged in parallel, for example, in other embodiments of the present technical solution, the third part 53 can also be constructed in a grid shape or a mesh shape, and the hollow of the grid or the mesh forms an airflow passage for airflow to pass through. The way to increase the heat dissipation surface area also belongs to the protection scope of the present application, and will not be described in detail here.

[0062] In order to effectively utilize the wind energy of the heat dissipation fan 30 and reduce the occupied space, as shown,Figure 1 , Figure 2 or Figure 4 As shown, in this embodiment of the invention, the third part 53 is located between the exhaust end 31 and the air inlet 210 of the cooling fan 30. When the cooling fan 30 is working, the external airflow blows and cools the third part 53 through the air inlet 210 before entering the exhaust end 31 of the cooling fan 30. For ease of installation, the frame 531 of the third part 53 is fixed to the surface of the exhaust end 31 of the cooling fan 30 by a locking member 500, so that the frame 531 fits tightly against the exhaust end 31 of the cooling fan 30. Thus, the hollow part of the frame 531 is constructed into an air guide cavity that communicates with the air outlet 311 of the exhaust end 31. Simultaneously, multiple heat sinks 532 are located within the air guide cavity and mounted on the exhaust outlet 311 of the cooling fan 30, ensuring that the airflow drawn in by the cooling fan 30 cools the multiple heat sinks 532 at high speed. Compared to the traditional hair removal device 1000 solution, which installs the heat dissipation structure downstream of the airflow of the cooling fan 30 and connects the air outlet 32 ​​of the cooling fan 30 to the heat dissipation components via a duct, this technical solution eliminates the need for long ducts to conduct airflow, thus avoiding energy loss. Furthermore, the multiple through-holes in the air inlet 210 enable high-speed airflow impact, further improving heat dissipation efficiency. The locking component 500 can be one or more of screws, clips, or connecting pins. To prevent the third part 53 from loosening due to minor vibrations of the cooling fan 30 during operation, the locking component 500 uses screws to secure the third part 53 to the cooling fan 30. Simultaneously, tightening the screws on the locking component 500 effectively presses the third part 53 firmly against the cooling fan 30.

[0063] At the same time, such as Figure 1 Combination Figure 2 As shown, in this embodiment of the invention, a sealing ring 70 is provided on the surface of the frame 531 facing away from the cooling fan 30. The two sides of the sealing ring 70 are respectively sealed to the inner wall of the frame 531 and the outer shell 200 with the air inlet 210, so that the inner ring surface of the sealing ring 70 is constructed into a unique air passage connecting the air inlet 210 and the air guide cavity. The sealing ring 70 can be made of a material with elastic properties, such as silicone or rubber, to ensure the sealing effect of the air passage.

[0064] Furthermore, such as Figure 1 Combination 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.

[0065] 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 reflector 330 is used to isolate the light source 320 and the air outlet window 3102. Specifically, 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.

[0066] At the same time, as Figures 1-4 shown in the embodiment of the present application, in order to further save the 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 in the direction 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.

[0067] Specifically, as Figure 1 , Figure 3 combined 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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 the plurality of heat dissipation plates 532 are each 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.

[0073] Further, as shown in Figure 1 In combination with Figure 2 In the embodiment of the present application, the gas flow is prevented from being concentrated in the second part 52, and the outer shell 200 is also provided with an auxiliary air outlet 230, which is constructed by a plurality of small holes, so that the gas flow in the second part 52 can be discharged through the auxiliary air outlet 230.

[0074] 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 being concentrated and ensure the stable operation 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 operation caused by the heat concentration of the transformer device 600.

[0075] 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 configured 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.

[0076] 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.

[0077] 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, which occupies a lot of 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, the hot airflow 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 hazards.

[0078] Further, the battery 700 and the transformer 600 can be separated by a heat insulation filler (not shown), thereby preventing heat concentration. The heat insulation filler can be made of porous material, such as foam, and the like, which is not limited here, so that when the cooling fan 30 works, the airflow in the space containing the battery 700 can flow, thereby accelerating heat dissipation.

[0079] 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.

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.
