Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0040] In the following, some embodiments of the present application will be described in detail with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0041] Please refer to Figures 1 to 3 , Figure 1 and Figure 2 are respectively the three-dimensional structural schematic diagrams of two different perspectives of the depilatory device provided by the present application.

[0042] As shown in Figures 1 to 3 , the depilatory device 100 at least includes a housing 10, a fan component 20 and a light source component 30. The housing 10 forms a containing space 104 with a first air vent 101, a second air vent 102 and a light outlet 103, and an air flow passage is formed between the first air vent 101 and the second air vent 102.

[0043] Optionally, the first air vent 101 can be one or more, and the multiple first air vents 101 can be arranged on the same side of the housing 10 or on different sides of the housing 10. Optionally, the second air vent 102 can also be one or more, and the multiple second air vents 102 can be arranged on the same side of the housing 10 or on different sides of the housing 10.

[0044] It can be understood that the first air vent 101 can serve as an air inlet, and the second air vent 102 can serve as an air outlet, or the first air vent 101 can serve as an air outlet, and the second air vent 102 can serve as an air inlet.

[0045] The fan component 20 is accommodated in the containing space 104 and is used to provide power for the air flow between the first air vent 101 and the second air vent 102, so that the air can flow from the first air vent 101 to the second air vent 102, or under the push of the power provided by the fan component 20, the air can flow from the second air vent 102 to the first air vent 101.

[0046] For the convenience of explanation, the first vent 101 is taken as the air inlet and the second vent 102 is taken as the air outlet in the present application. Under the action of the fan component 20, air can flow from the first vent 101 to the second vent 102 and be discharged from the housing 10 through the second vent 102, so as to enhance the convection of air and the devices arranged in the accommodating space 104 of the housing 10, thereby achieving the heat dissipation of the devices arranged in the accommodating space 104 of the housing 10.

[0047] As shown in Figures 3 to 5 , the light source component 30 is accommodated in the accommodating space 104 formed by the housing 10 and is used to provide light and output the light illumination through the light outlet 103. The light source component 30 comprises a light reflecting component 31 and a light source assembly 32, and the light source assembly 32 is arranged corresponding to the light outlet 103 and is used to provide light illumination. The light reflecting component 31 is arranged corresponding to the light source assembly 32 and is used to reflect the light emitted by the light source assembly 32, thereby enhancing the light illumination intensity of the light output by the light source component 30 through the light outlet 103.

[0048] The light reflecting component 31 has opposite first and second sides, the first side of the light reflecting component 31 is the side far away from the light outlet 103, and the second side of the light reflecting component 31 is the side close to the light outlet 103. After the light reflecting component 31 is installed on the housing 10, the first side of the light reflecting component 31 has a first gap 40 with the housing 10, the second side of the light reflecting component 31 is formed with a light reflecting groove 310, the light source assembly 32 is at least partially accommodated in the light reflecting groove 310 and has a second gap 50 with the light reflecting groove 310, and the first vent 101 can at least communicate with the second vent 102 through the first gap 40 and the second gap 50 to form an air flow channel, as shown in Figure 3 .

[0049] In the embodiment, the light-reflecting component 31 has opposite first and second sides, and after the light-reflecting component 31 is installed to the housing 10, a first gap 40 is formed between the first side of the light-reflecting component 31 and the housing 10, and the light-reflecting component 31 is provided with a light-reflecting groove 310 on the two sides close to the light outlet 103. The light source assembly 32 is partially accommodated in the light-reflecting groove 310 and a second gap 50 is formed between the light-reflecting groove 310 and the light source assembly 32. At the same time, the first ventilation port 101 is in communication with the second ventilation port 102 through the first gap 40 and the second gap 50 to form an air flow channel. Thus, during the operation of the fan component 20, the air flow between the first ventilation port 101 and the second ventilation port 102 can be pushed to pass through the first gap 40 and the second gap 50 to take away the heat generated by the operation of the light source assembly 32 and the heat transferred to the light-reflecting component 31 by the light source assembly 32. Further, the first gap 40 and the second gap 50 are respectively located on the opposite sides of the light-reflecting component 31, so that the flowing air can be used to dissipate heat from the light-reflecting component 31 from the two opposite sides, and finally a more optimal heat dissipation effect can be achieved for the light source component 30.

[0050] In some embodiments, the side of the light-reflecting component 31 away from the light outlet 103 is further provided with fins 314, that is, the first side of the light-reflecting component 31 is further provided with fins 314 to increase the contact area of the light-reflecting component 31 with air. Alternatively, a plurality of fins 314 are arranged at intervals on the side of the light-reflecting component 31 away from the light source assembly 32, and the extending direction of the fins 314 is the same as the extending direction of the light source assembly 32.

[0051] In the embodiment, the first side of the light-reflecting component 31 is further provided with fins 314, so that the contact area of the light-reflecting component 31 with air can be effectively increased, and the heat dissipation performance of the light-reflecting component 31 is further improved. Further, the heat dissipation performance of the light-reflecting component 31 can be further improved by arranging a plurality of fins 314 at intervals. Further, the extending direction of the fins 314 is the same as the extending direction of the light source assembly 32, so that the air flow between the first ventilation port 101 and the second ventilation port 102 is less hindered, and the heat dissipation effect of the fan component 20 on the light source component 30 can be further improved.

[0052] In some embodiments, the side of the light-reflecting component 31 away from the light outlet 103 is attached with a heat-conducting patch, and the heat-conducting efficiency of the heat-conducting patch is greater than the heat-conducting efficiency of the light-reflecting component 31. The heat-conducting patch includes but is not limited to a graphite sheet.

[0053] In the embodiment, the light-reflecting component 31 is provided with a high-heat-conducting patch, and the high-heat-conducting patch is more likely to conduct heat away from the light-reflecting component 31 due to the high-heat-conducting property, so that the heat dissipation performance of the light-reflecting component 31 can be further improved.

[0054] In some embodiments, the light-reflecting component 31 is detachably connected with the housing 10. It can be understood that the detachable connection between the light-reflecting component 31 and the housing 10 includes, but is not limited to, structural engagement, interference fit, threaded connection, screw connection, etc. By setting the connection between the light-reflecting component 31 and the housing 10 as detachable, the installation and adjustment of the light source component 30 are facilitated.

[0055] Please refer to Figure 6 In some embodiments, the hair removal device 100 further comprises a first support component 11 and a second support component 12 which are detachably connected with the housing 10. The second support component 12 is provided with a first limiting portion 121 and a second limiting portion 122. The first limiting portion 121 forms a limiting fit with the light-reflecting component 31 in a first direction, and the second limiting portion 122 forms a limiting fit with the light-reflecting component 31 in a second direction. The first support component 11 abuts against the light-reflecting component 31 in a third direction and forms a limiting fit with the light-reflecting component 31 in the third direction in cooperation with the second support component 12. The first direction is the extension direction of the light-reflecting groove 310, and the first direction, the second direction and the third direction are perpendicular to each other.

[0056] In the present embodiment, the light-reflecting component 31 is installed in the support components (the first support component 11 and the second support component 12), and is limited and fixed by the support components and installed in the housing 10. This not only facilitates the installation of the light-reflecting component 31 in the housing, but also realizes the detachable connection between the light-reflecting component 31 and the housing 10, which can effectively avoid the influence of the screws on the hardware reliability of the light-reflecting component 31 or the housing 10.

[0057] As shown in Figure 6 In some embodiments, the light-reflecting groove 310 formed by the light-reflecting component 31 has at least a first opening 311, a second opening 312 and a third opening 313. The first opening 311 and the second opening 312 are located on opposite sides of the extension direction of the light-reflecting groove 310, and the third opening 313 is arranged corresponding to the light outlet 103. The light reflected by the light-reflecting component 31 can be emitted to the light outlet 103 through the third opening 313.

[0058] Optionally, the length of the third opening 313 is greater than the length of the light outlet 103, and optionally, the width of the third opening 313 is greater than the width of the light outlet 103.

[0059] In this embodiment, the light reflection groove 310 is arranged in an open type, so that the resistance to air flow can be effectively reduced, and the light reflection component 31 and the light source assembly 32 of the light source component 30 can be better cooled during the process of the fan component 20 pushing the air with the diameters of the first air vent 101 and the second air vent 102 to flow. Further, the third opening 313 is arranged corresponding to the light outlet 103, and the length of the third opening 313 is greater than the length of the light outlet 103, and / or the width of the third opening 313 is greater than the width of the light outlet 103, so that the light source assembly 32 can emit more light through the third opening 313 to the light outlet 103, thereby effectively enhancing the light emission amount of the light outlet 103.

[0060] Please refer to Figures 7 to 8 In some embodiments, the light reflection component 31 has a first light reflection part 315 and a second light reflection part 316 connected with each other, and a connecting protrusion 317 is formed at the connection between the first light reflection part 315 and the second light reflection part 316. The first light reflection part 315 forms a first arc-shaped light reflection area 3151, and the second light reflection part 316 forms a second arc-shaped light reflection area 3161, and at least the first arc-shaped light reflection area 3151 and the second arc-shaped light reflection area 3161 constitute the light reflection groove 310.

The height of the highest point of the first arc-shaped light reflection area 3151 near the side surface of the light source assembly 32 and the height of the highest point of the second arc-shaped light reflection area 3161 near the side surface of the light source assembly 32 are both greater than the height of the connecting protrusion 317 near the side surface of the light source assembly 32.

[0062] Optionally, the width W of the connecting protrusion 317 satisfies 0.6mm≥W>0, and the height H of the connecting protrusion 317 satisfies 5mm≥H≥2.5. For example, the width W of the connecting protrusion 317 can be, but is not limited to, 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc. The height H of the connecting protrusion 317 can be, but is not limited to, 2.5mm, 2.6mm, 3mm, 4mm, etc.

[0063] In this embodiment, at least two arc-shaped light reflection areas are arranged in the light reflection component 31, and the light reflection groove 310 is formed by connecting the at least two arc-shaped light reflection areas. The connecting protrusion 317 formed in the light reflection groove 310 can increase the reflection area of the light reflection groove 310 to enhance the reflection effect of the light reflection component 31 on the light emitted by the light source assembly 32, and can also increase the contact area between the light reflection component 31 and the air, thereby further improving the heat dissipation performance of the light reflection component 31.

[0064] In some embodiments, the light source assembly 32 comprises a first light source member 321 and a second light source member 322 arranged in a spaced manner, wherein the first light source member 321 is arranged corresponding to the first arc-shaped light reflection area 3151, and the second light source member 322 is arranged corresponding to the second arc-shaped light reflection area 3161.

[0065] In the present embodiment, by arranging the two light source members of the light source assembly 32 in a spaced manner, the light emitting area of the light source assembly 32 is effectively increased, and the light emitting effect of the light source assembly 32 is enhanced. Meanwhile, air can flow between the gaps between the two light source members (e.g., the first light source member 321 and the second light source member 322), so as to effectively dissipate heat from the light source members, and the heat dissipation effect of the fan component 20 on the light source component 30 can be ultimately improved.

[0066] Please refer to Figure 9 In some embodiments, the light reflection component 31 comprises a heat dissipation member 31a and a light reflection member 31b, wherein the heat dissipation member 31a is mounted to the housing 10 and forms a groove, and the light reflection member 31b is arranged corresponding to the groove so that the groove forms a light reflection groove 310.

Meanwhile, the heat dissipation member 31a is in contact with air to achieve effective heat dissipation of the light reflection component 31.

[0069] Further, a heat conduction medium is arranged between the heat dissipation member 31a and the light reflection member 31b, which includes but is not limited to silicone grease. Alternatively, the heat dissipation member 31a is arranged with a metal or alloy heat dissipation member 31a so that the heat dissipation member 31a can better dissipate heat from the light reflection member 31b.

[0070] It can be understood that the light reflection component 31 is also a metal or alloy light reflection component, which is formed with a groove, and the groove is formed into a light reflection groove by electroplating a light reflection plating layer in the groove, or the groove is formed into a light reflection groove by polishing the surface of the groove to increase the reflectivity of the surface of the groove. Optionally, the metal or alloy light reflection component is arranged with fins 314 on the side away from the side where the groove is formed.

[0071] Please refer to Figure 5In some embodiments, the hair removal device 100 further comprises a filter 60, which is arranged on the light path of the light source component 30 and located on the side of the light source assembly 32 away from the reflecting component 31, and there is a fourth gap 319 between the light source assembly 32 and the filter 60. The first vent 101 can communicate with the second vent 102 through the first gap 40, the second gap 50 and the fourth gap 319 to form an air flow channel. Optionally, the filter 60 is a mica filter.

[0072] In this embodiment, by arranging the filter 60, the light emitted by the light source assembly 32 (such as ultraviolet light) is filtered to avoid damage to the skin caused by the irradiation of part of the light during the process of removing hair from the skin. At the same time, there is a fourth gap 319 between the light source assembly 32 and the filter, and the air flowing through the fourth gap 319 can further carry away the heat generated by the light source assembly 32 during operation.

[0073] As shown in Figures 2 to 3 In some embodiments, the hair removal device 100 further comprises a power supply component 70, which is connected to the light source component 30 and the fan component 20, and the light source component 30 and the fan component 20 can be powered through the power supply component 70.

[0074] For example, the power supply component 70 includes but is not limited to a power supply battery and a power supply interface. When the power supply component 70 includes a power supply battery, the power supply battery can be built-in in the housing of the hair removal device, so that the hair removal device does not need to be powered through a corresponding power adapter, and the portability of the hair removal device is enhanced. When the power supply component 70 includes a power supply interface, the hair removal device can be provided without a built-in power supply battery, which facilitates the miniaturization of the hair removal device. It can be understood that the power supply component 70 can further include a power supply control component 701, which is used to control the on-off of the conduction path between the power supply component 70 and the light source component 30 and the fan component 20. For example, the power supply control component 701 is a power supply control circuit board integrated with a power supply control circuit and / or a power supply control chip, and the power supply control component 701 has a switchable conduction state and an off state. When the power supply control component 701 is in the conduction state, the conduction path between the power supply component 70 and the light source component 30 and the fan component 20 is turned on, and the light source component 30 and the fan component 20 can be powered through the power supply component 70. When the power supply control component 701 is in the off state, the conduction path between the power supply component 70 and the light source component 30 and the fan component 20 is turned off, and the light source component 30 and the fan component 20 are powered off.

[0075] The switching operation between the on state and the off state of the power supply control component 701 can be performed by triggering the trigger of the power supply control component 701, which includes but is not limited to a mechanical button, a touch button. The form of the trigger of the trigger of the power supply control component 701 includes but is not limited to pressing, sliding, and fluctuating the trigger.

[0076] As shown in Figures 2 to 3 The power supply interface is connected to the power supply control component 701 and connects the light source component 30 and the fan component 20 through the power supply control component 701. The power supply interface can be adapted to an external power adapter to convert the mains power into an electrical signal (such as working voltage or working current) that can be used by the hair removal instrument 100 to work, and then output the converted electrical signal to the power supply control component 701 through the power supply interface, so as to supply power to the light source component 30 and the fan component 20 through the power supply control component 701.

[0077] Alternatively, when the working electrical signals required by the light source component 30 and the fan component 20 are different, the power supply control component 701 further includes a signal conversion circuit for further converting the received electrical signal output by the power adapter into an electrical signal required by the light source component 30 and the fan component 20 to work. For example, the working voltage required by the light source component 30 is a first voltage, and the working voltage required by the fan component 20 is a second voltage. The signal conversion circuit can convert the received electrical signal output by the power adapter into the first voltage and the second voltage, so that the light source component 30 and the fan component 20 can work normally.

[0078] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed in the present application, and these modifications or replacements should be covered within the protection scope of the present application.
