Description

Technical Field

[0001] This application relates to the field of hair removal device technology, and more particularly to a flashing component and a hair removal device. Background Technology

[0002] A hair removal device is a beauty instrument used for hair removal. It typically includes a flash unit, control circuitry, energy storage unit, and housing. The flash unit is located inside the housing and usually includes a lamp and a reflector. The lamp emits light outwards, and the reflector reflects the light to a light outlet on the housing, allowing the light to be emitted through the outlet.

[0003] In related technologies, light leakage is usually prevented by blocking both ends of the reflector cup along the axial direction of the lamp tube, thus improving the aesthetics of the hair removal device and reducing safety risks. However, since the reflector cup has a cooling air duct through which the cooling air for cooling the lamp tube flows, blocking both ends of the reflector cup also blocks both ends of the air duct, which is detrimental to the heat dissipation of the lamp tube. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the related technologies, this application provides a flashing component and a hair removal device to solve the problem that the reflector cups blocked at both ends in the related technologies are not conducive to the heat dissipation of the lamp tube.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides a flash assembly comprising:

[0006] A reflector cup having a cooling air duct, and an air inlet and an air outlet communicating with the cooling air duct are provided on the reflector cup;

[0007] A light source is disposed in the cooling air duct, and the reflector is used to reflect the light emitted by the light source;

[0008] A light-shielding element is disposed on the side of the reflector cup near the air inlet, the light-shielding element is used to block the light from escaping from the air inlet, and there is a gap between the light-shielding element and the reflector cup, the gap allowing cooling air to enter the cooling air duct; and / or, the light-shielding element is disposed on the side of the reflector cup near the air outlet, the light-shielding element is used to block the light from escaping from the air outlet, the light-shielding element and the reflector cup have a gap allowing cooling air in the cooling air duct to exit.

[0009] In this application, the reflector cup has a cooling air duct, and the reflector cup is provided with an air inlet and an air outlet that communicate with the cooling air duct. The light source is located in the cooling air duct. Furthermore, a light shield is provided on the side of the reflector cup near the air inlet and / or air outlet. The light shield is used to block the light emitted by the light source from escaping from the air inlet and / or air outlet. Therefore, this application can block the light at the air inlet and / or air outlet through the light shield, which helps to prevent the light emitted by the light source from leaking out from the air inlet and / or air outlet. This, in turn, helps to improve the aesthetics of the hair removal device using this flash component and helps to reduce safety risks.

[0010] Furthermore, since there is a gap between the light-shielding component and the reflector, and when the light-shielding component is placed near the air inlet, the gap allows cooling air to enter the cooling duct, and when the light-shielding component is placed near the air outlet, the gap allows cooling air in the cooling duct to be discharged. Therefore, this application can use the light-shielding component to block light at the air inlet and / or air outlet, and can also prevent the air inlet and / or air outlet from being blocked through the gap between the light-shielding component and the reflector, thereby ensuring that cooling air can normally enter and / or exit the cooling duct, which is beneficial to the heat dissipation of the light source.

[0011] In a possible implementation of the first aspect, the light-shielding member and the air inlet are arranged along a first direction, and the inner edge of the air inlet is projected along the first direction onto the first inlet projection of the light-shielding member, which is located inside the outer edge of the light-shielding member, or coincides with the outer edge of the light-shielding member; and / or,

[0012] The light-shielding member and the air outlet are arranged along the second direction. The inner edge of the air outlet is projected along the second direction onto the first outlet projection of the light-shielding member, which is located inside the outer edge of the light-shielding member or coincides with the outer edge of the light-shielding member.

[0013] Setting the first inlet projection and / or the first outlet projection inside the outer edge of the light shield or coinciding with the outer edge of the light shield helps to ensure that the light shield can block the air inlet and / or air outlet, thereby helping to ensure that the light shield can effectively block the light at the air inlet and / or air outlet, and thus helping to ensure the light shielding effect of the light shield.

[0014] In a possible implementation of the first aspect, the inner edges of both the air inlet and the air outlet are located on the inner sidewall of the reflector, and the outer edges of both the air inlet and the air outlet are located on the outer sidewall of the reflector.

[0015] The outer edge of the air inlet is projected along the first direction onto the second inlet of the light shield, which is located inside the outer edge of the light shield; and / or, the outer edge of the air outlet is projected along the second direction onto the second outlet of the light shield, which is located inside the outer edge of the light shield.

[0016] The second inlet projection and / or the second outlet projection are positioned inside the outer edge of the light shield, which allows the light shield to better block the air inlet and / or outlet, ensuring that light does not leak out from the air inlet and / or outlet from all angles. Even under complex light path reflection conditions, it can effectively prevent light leakage, which helps to further ensure the light shielding effect of the light shield and further improve safety and aesthetics.

[0017] In a possible implementation of the first aspect, the distance between the second inlet projection and the outer edge of the light-shielding member is at least partially greater than 0.5 mm; and / or, the distance between the second outlet projection and the outer edge of the light-shielding member is at least partially greater than 0.5 mm.

[0018] With this setting, a spacing greater than 0.5mm can provide a buffer zone for the light-shielding component. Even if the light intensity of the light source fluctuates or the reflected light path of the reflector cup changes slightly due to some external factors (such as slight vibration), the light-shielding component can still stably perform its light-shielding function through this spacing. This helps to prevent some light from scattering out at an uncontrollable angle, thereby reducing the risk of light leakage under complex reflection conditions.

[0019] In one possible implementation of the first aspect, the light-shielding member and the reflector are arranged in a third direction, and the gap between the light-shielding member and the reflector in the third direction is greater than or equal to 3 mm.

[0020] This configuration provides a sufficiently wide channel for cooling air, allowing it to enter and exit the cooling duct more smoothly. This ensures that the cooling air effectively removes the heat generated by the light source with sufficient flow and speed, improving the heat dissipation efficiency of the light source. It also helps maintain the operating temperature of the light source within a suitable range, thereby extending the lifespan of the light source.

[0021] In one possible implementation of the first aspect, the light-shielding element is a mica light-shielding element.

[0022] This design serves several purposes. Firstly, because mica has excellent opacity, it can effectively block the penetration of light. Therefore, setting the light-shielding component as a mica light-shielding component enhances its light-shielding effect and facilitates its light-shielding function.

[0023] Secondly, because mica is heat-resistant, it can maintain stable performance in high-temperature environments and will not deform, be damaged, or lose its light-blocking effect due to heat. Therefore, using mica as the light-blocking component enhances its heat resistance, facilitates its use in hair removal devices, and also solves the problem that other plastic materials are not heat-resistant and cannot be used in parts near the light source of hair removal devices.

[0024] Thirdly, by utilizing the non-conductive property of mica, the creepage distance is increased, thereby improving the safety performance of the product.

[0025] In a possible implementation of the first aspect, the light-shielding member and the reflector are arranged in the third direction;

[0026] The light source is provided with a limiting structure, which includes a limiting surface. The limiting surface and the light-shielding member are engaged in a limiting cooperation through surface-to-surface contact in the third direction.

[0027] The face-to-face contact between the limiting surface and the light-shielding component precisely defines the installation position of the light-shielding component. This ensures the stability of the installation position, the stability and reliability of the light-shielding effect, and the stability of the gap between the light-shielding component and the reflector, facilitating the smooth entry and / or exit of cooling air into the cooling duct. Furthermore, the face-to-face contact limiting method provides a clear positioning reference for the installation of the light-shielding component, allowing technicians to quickly install it in the correct position, reducing assembly errors and improving the overall product quality.

[0028] In one possible implementation of the first aspect, the light source is a lamp tube, the limiting structure is an insulating member disposed at the axial end of the lamp tube, and the limiting surface is located on the side of the insulating member facing away from the lamp tube.

[0029] This design, through the use of insulating components, not only effectively prevents current leakage and isolates electrical interference between the lamp tube and other metal parts, but also facilitates the placement of the limiting structure on the light source.

[0030] In one possible implementation of the first aspect, the insulating element includes a large-diameter section, a small-diameter section, and a stepped surface connecting the large-diameter section and the small-diameter section, the large-diameter section being sleeved on the outside of the lamp tube, and the stepped surface serving as the limiting surface.

[0031] The stepped structure provides a clear and stable positioning reference for the light-shielding component, allowing it to remain in the correct position based on this stable stepped surface. This ensures effective blocking of light leakage from the air inlet and / or outlet, thereby enhancing the stability and reliability of the light-shielding effect.

[0032] In one possible implementation of the first aspect, the light-shielding member is provided with a clearance hole for the small-diameter section to pass through.

[0033] This design ensures that, on the one hand, the fit between the clearance hole and the small diameter section provides a clear positioning point for the light-shielding component during installation. This allows the light-shielding component to move accurately along the small diameter section to the position where it contacts the step surface when the small diameter section passes through the clearance hole, thus achieving precise positioning and fitting.

[0034] On the other hand, the presence of clearance holes makes the installation of the light-shielding component more convenient. Workers can directly align the clearance holes of the light-shielding component with the small-diameter section for installation, without having to painstakingly find the correct installation position. This design reduces uncertainty and error rates during the installation process, making the installation process smoother and more efficient.

[0035] In one possible implementation of the first aspect, the light-shielding member is provided with a fixing part, which is used to connect to a fixing structure on the hair removal device;

[0036] The inner peripheral wall of the clearance hole is spaced apart from the outer peripheral wall of the small diameter section.

[0037] This design serves two purposes. First, by connecting the fixing part on the light-shielding component to the fixing structure on the hair removal device, the light-shielding component is easily fixed on the device, ensuring the reliability of its position. Second, by spacing the inner peripheral wall of the clearance hole from the outer peripheral wall of the small-diameter section, the light-shielding component can be prevented from exerting force on the lamp tube in the radial direction, thereby reducing its impact on the lamp tube. It also facilitates the passage of the small-diameter section through the clearance hole.

[0038] In one possible implementation of the first aspect, the distance between the inner peripheral wall of the clearance hole and the outer peripheral wall of the small diameter section is greater than 0.5 mm.

[0039] This design serves two purposes: firstly, it ensures that the light-shielding component does not exert force on the lamp tube radially; secondly, it facilitates the passage of the small-diameter section through the clearance hole while also ensuring the positioning accuracy of the light-shielding component on the insulating component.

[0040] Secondly, this application also provides a hair removal device, which includes:

[0041] The hair removal device body includes a shell and a flash component as described in any of the first aspects. The shell is provided with a light outlet, and the flash component is disposed inside the shell. The light outlet is for the light emitted by the light source to be emitted.

[0042] A power supply assembly is connected to the hair removal device body or disposed within the housing, and the power supply assembly is used to supply power to the hair removal device body.

[0043] In this application, on the one hand, the light-shielding component can block light at the air inlet and / or air outlet, thereby preventing light emitted from the light source from leaking out of the air inlet and / or air outlet, thus improving the aesthetics of the hair removal device using this flash component and reducing safety risks. On the other hand, the gap between the light-shielding component and the reflector cup can also prevent the air inlet and / or air outlet from being blocked, thus ensuring that cooling air can normally enter and / or exit the cooling duct, which is beneficial for heat dissipation of the light source.

[0066] As described in the background section of this application, a hair removal device is a beauty instrument used for hair removal, which typically includes a flash assembly, a control circuit, an energy storage unit, and a housing. The flash assembly is housed within the housing and typically includes a lamp tube and a reflector. The lamp tube emits light outwards, and the reflector reflects the light to a light outlet on the housing, allowing the light to be emitted through the outlet.

[0067] In related technologies, light leakage is usually prevented by blocking both ends of the reflector cup along the axial direction of the lamp tube, thus improving the aesthetics of the hair removal device and reducing safety risks. However, since the reflector cup has a cooling air duct through which the cooling air for cooling the lamp tube flows, blocking both ends of the reflector cup also blocks both ends of the air duct, which is detrimental to the heat dissipation of the lamp tube.

[0068] Example 1

[0069] In view of the above-mentioned problems, this application provides a flash assembly to solve the problem that the reflector cups blocked at both ends in the related art are not conducive to the heat dissipation of the lamp tube.

[0070] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0071] like Figure 1 and Figure 2 As shown, the flash assembly 100 includes a reflector cup 1, a light source 2, and a light shield 3. The reflector cup 1 has a cooling air duct 11, and the reflector cup 1 is provided with an air inlet 12 and an air outlet 13 that communicate with the cooling air duct 11. The light source 2 is disposed in the cooling air duct 11, and the reflector cup 1 is used to reflect the light emitted by the light source 2.

[0072] A light-shielding element 3 is disposed on the side of the reflector cup 1 near the air inlet 12. The light-shielding element 3 is used to block light from escaping from the air inlet 12. A gap 4 is provided between the light-shielding element 3 and the reflector cup 1, allowing cooling air to enter the cooling air duct 11. And / or, the light-shielding element 3 is disposed on the side of the reflector cup 1 near the air outlet 13. The light-shielding element 3 is used to block light from escaping from the air outlet 13. A gap 4 is provided between the light-shielding element 3 and the reflector cup 1, allowing cooling air in the cooling air duct 11 to exit.

[0073] In this application, the reflector cup 1 has a cooling air duct 11, and the reflector cup 1 is provided with an air inlet 12 and an air outlet 13 that communicate with the cooling air duct 11. The light source 2 is located in the cooling air duct 11. Furthermore, a light shield 3 is provided on the side of the reflector cup 1 near the air inlet 12 and / or the air outlet 13. The light shield 3 is used to block the light emitted by the light source 2 from being emitted from the air inlet 12 and / or the air outlet 13. Therefore, this application can provide light shielding at the air inlet 12 and / or the air outlet 13 through the light shield 3, which helps to prevent the light emitted by the light source 2 from leaking out from the air inlet 12 and / or the air outlet 13. This, in turn, helps to improve the aesthetics of the hair removal device using the flash component 100 and helps to reduce safety risks.

[0074] Furthermore, since there is a gap 4 between the light-shielding member 3 and the reflector cup 1, and when the light-shielding member 3 is set near the air inlet 12, the gap 4 allows cooling air to enter the cooling air duct 11, and when the light-shielding member 3 is set near the air outlet 13, the gap 4 allows cooling air in the cooling air duct 11 to be discharged. Therefore, this application can use the light-shielding member 3 to shield the light at the air inlet 12 and / or the air outlet 13, and can also prevent the air inlet 12 and / or the air outlet 13 from being blocked through the gap 4 between the light-shielding member 3 and the reflector cup 1, thereby ensuring that the cooling air can normally enter and / or exit the cooling air duct 11, which is beneficial to the heat dissipation of the light source 2.

[0075] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, a light-shielding member 3 is provided on the side of the reflector cup 1 near the air inlet 12, and a light-shielding member 3 is provided on the side of the reflector cup 1 near the air outlet 13.

[0076] With this configuration, the light-shielding components 3 on both sides can simultaneously block the air inlet 12 and the air outlet 13 of the cooling air duct 11, thereby effectively blocking light from escaping from the air inlet 12 and the air outlet 13. This helps to further improve the light-shielding performance of the flash assembly 100 and further enhance the safety of use.

[0077] Furthermore, such as Figure 1 and Figure 2 As shown, the light shield 3 and the air inlet 12 are along the first direction (e.g. Figure 2 Arrangement in the X1 direction, such as Figure 3 As shown, the inner edge b1 of the air inlet 12 is projected along the first direction onto the first inlet projection 6 of the light shield 3, located inside the outer edge a of the light shield 3, or coinciding with the outer edge a of the light shield 3. And / or, as... Figure 2 As shown, the light shield 3 and the air outlet 13 are along the second direction (e.g. Figure 2 Arranged in the X2 direction, the inner edge of the air outlet 13 is projected along the second direction onto the first outlet of the light shield 3. The projection is located inside the outer edge a of the light shield 3, or coincides with the outer edge a of the light shield 3.

[0078] Setting the first inlet projection 6 and / or the first outlet projection inside the outer edge a of the light shield 3 or coinciding with the outer edge a of the light shield 3 helps to ensure that the light shield 3 can block the air inlet 12 and / or the air outlet 13, thereby helping to ensure that the light shield 3 can effectively block the light at the air inlet 12 and / or the air outlet 13, and thus helping to ensure the light shielding effect of the light shield 3.

[0079] In a preferred embodiment, the first direction is parallel to the second direction in relation to the first and second directions. This arrangement, to a certain extent, simplifies the arrangement between the reflector 1 and the light-shielding member 3, thereby facilitating their arrangement. Simultaneously, in other directions intersecting with the first and second directions, it helps reduce the space occupied by the flash assembly 100, further facilitating its arrangement.

[0080] In other implementations, the first direction may also intersect with the second direction, and the angle between the first direction and the second direction can be any value, making the setting between the first direction and the second direction more flexible.

[0081] Furthermore, such as Figure 1 As shown, the inner edges of the air inlet 12 and the air outlet 13 are located on the inner wall 14 of the reflector cup 1, and the outer edges of the air inlet 12 and the air outlet 13 are located on the outer wall 15 of the reflector cup 1.

[0082] like Figure 3 As shown, the outer edge b2 of the air inlet 12 is projected along the first direction onto the second inlet projection 7 of the light shield 3, which is located inside the outer edge a of the light shield 3; and / or, the outer edge of the air outlet 13 is projected along the second direction onto the second outlet projection of the light shield 3, which is located inside the outer edge a of the light shield 3.

[0083] The second inlet projection 7 and / or the second outlet projection are positioned inside the outer edge a of the light shield 3. This allows the light shield 3 to better block the air inlet 12 and / or the air outlet 13, ensuring that light does not leak out from the air inlet 12 and / or the air outlet 13 from all angles. Even under complex light path reflection conditions, it can effectively prevent light leakage, which helps to further ensure the light shielding effect of the light shield 3 and further improve safety and aesthetics.

[0084] Additionally, it should be noted that the illustrations of the first inlet projection 6 and the second inlet projection 7 on the light-shielding member 3 are the same as those of the first outlet projection and the second outlet projection on the light-shielding member 3. Therefore, this embodiment only shows the first inlet projection 6 and the second inlet projection 7.

[0085] In a preferred embodiment, the first inlet projection 6 and the second inlet projection 7 are both located inside the outer edge a of the light-shielding member 3, and the first outlet projection and the second outlet projection are both located inside the outer edge a of the light-shielding member 3.

[0086] This arrangement allows the light-shielding components 3 on both sides to better block the air inlet 12 and the air outlet 13, ensuring that light does not leak out from the air inlet 12 and the air outlet 13 from all angles. Even under complex light path reflection conditions, it can effectively prevent light leakage, which helps to further ensure the light-shielding effect of the light-shielding component 3 and further improve safety and aesthetics.

[0087] Furthermore, such as Figure 3 As shown, the distance between the second inlet projection 7 and the outer edge a of the light shield 3 is at least partially greater than 0.5 mm; and / or, the distance between the second outlet projection and the outer edge a of the light shield 3 is at least partially greater than 0.5 mm.

[0088] With this setting, a spacing greater than 0.5mm can provide a buffer area for the light-shielding component 3. Even if the light intensity of the light source 2 fluctuates to a certain extent, or the reflected light path of the reflector cup 1 changes slightly due to some external factors (such as slight vibration), the light-shielding component 3 can still stably play a light-shielding role through this spacing. This helps to prevent some light from scattering out at an uncontrollable angle, thereby reducing the risk of light leakage under complex reflection conditions.

[0089] In a preferred embodiment, the distance between the second inlet projection 7 and the outer edge a of the light-shielding member 3 is greater than 0.5 mm, and the distance between the second outlet projection and the outer edge a of the light-shielding member 3 is greater than 0.5 mm.

[0090] With this setup, the light-blocking components 3 on both sides of the reflector cup 1 can stably perform their light-blocking function through a spacing greater than 0.5mm. This helps to further prevent some light from scattering out at uncontrollable angles, thereby further reducing the risk of light leakage under complex reflection conditions.

[0091] In this embodiment, the distance between the second inlet projection 7 and the outer edge a of the light shield 3 can be any value within the range of 0.6mm, 0.7mm or greater than 0.5mm. The size of this distance is flexible and can be set according to actual needs. This embodiment does not impose any specific limitation on this.

[0092] In this embodiment, the distance between the projection of the second exit and the outer edge a of the light-shielding member 3 can be any value within the range of 0.6mm, 0.7mm or greater than 0.5mm. The size of this distance is set flexibly. Specifically, it can be set according to actual needs. This embodiment does not make specific limitations on this.

[0093] Regarding gap 4, further, the light-shielding element 3 and the reflector cup 1 are in a third direction (such as...). Figure 2 Arranged in the X direction, the gap 4 between the light-shielding element 3 and the reflector cup 1 in the third direction is greater than or equal to 3mm.

[0094] This configuration provides a sufficiently wide channel for cooling air, allowing it to enter or exit the cooling air duct 11 more smoothly. This ensures that the cooling air effectively removes the heat generated by the light source 2 with sufficient flow and speed, improving the heat dissipation efficiency of the light source 2. This helps maintain the operating temperature of the light source 2 within a suitable range, thereby extending the service life of the light source 2.

[0095] In this embodiment, the gap 4 can be any value within the range of 3mm, 4mm, or greater than or equal to 3mm. The size of the gap 4 is set flexibly. Specifically, it can be set according to actual needs. This embodiment does not impose any specific limitations on this.

[0096] In a preferred embodiment, the third direction is parallel to both the first and second directions, as well as the first direction. This arrangement, to a certain extent, simplifies the arrangement between the reflector 1 and the light-shielding member 3, thereby facilitating their arrangement.

[0097] Furthermore, the light-shielding component 3 is a mica light-shielding component.

[0098] With this configuration, firstly, since mica has good opacity and can effectively block the penetration of light, setting the light-shielding component 3 as a mica light-shielding component is beneficial to enhancing the light-shielding effect of the light-shielding component 3 and facilitating the light-shielding of the light-shielding component 3.

[0099] Secondly, because mica is heat-resistant, it can maintain stable performance in high-temperature environments and will not deform, be damaged, or lose its light-blocking effect due to heat. Therefore, setting the light-blocking component 3 as a mica light-blocking component enhances its heat resistance, facilitates its use in hair removal devices, and also solves the problem that other plastic materials are not heat-resistant and cannot be used in parts near the light source of hair removal devices.

[0100] Thirdly, by utilizing the non-conductive property of mica, the creepage distance is increased, thereby improving the safety performance of the product.

[0101] Regarding the position setting of the light-shielding element 3, further, such as Figure 1 and Figure 2 As shown, a limit structure 5 is provided on the light source 2, such as... Figure 4 As shown, the limiting structure 5 includes a limiting surface 51, and the limiting surface 51 and the light-shielding member 3 are in a third direction (e.g., Figure 2 The limiting fit is achieved through surface-to-surface contact in the X direction (of the model).

[0102] The face-to-face contact between the limiting surface 51 and the light-shielding component 3 precisely defines the installation position of the light-shielding component 3. This helps ensure the stability of the installation position of the light-shielding component 3, the stability and reliability of the light-shielding effect, and the stability of the gap between the light-shielding component 3 and the reflector cup 1, ensuring smooth entry and exit of cooling air into and out of the cooling air duct 11. Furthermore, the face-to-face contact limiting method provides a clear positioning reference for the installation of the light-shielding component 3, allowing technicians to quickly install it in the correct position, reducing assembly errors and improving the overall quality of the product.

[0103] In other embodiments, the light-shielding member 3 may also be spaced apart from the light source 2. In this case, the limiting structure 5 may not be provided on the light source 2, that is, the light-shielding member 3 does not engage with the limiting structure 5 on the light source 2. This arrangement simplifies the structural composition of the flash assembly 100 to a certain extent and facilitates the manufacturing of the flash assembly 100.

[0104] Furthermore, such as Figure 1 and Figure 2 As shown, the light source 2 is a lamp tube, and the limiting structure 5 is an insulating component disposed at the axial end of the lamp tube. The limiting surface 51 is located on the side of the insulating component facing away from the lamp tube.

[0105] This configuration, through the use of insulating components, not only effectively prevents current leakage and isolates electrical interference between the lamp tube and other metal parts, but also facilitates the placement of the limiting structure 5 on the light source 2.

[0106] In other embodiments, the limiting structure 5 can be integrally formed on the light source 2, that is, the limiting surface 51 is disposed on the light source 2. This arrangement can reduce the number of components of the flash assembly 100, which is beneficial to reducing the manufacturing cost of the flash assembly 100.

[0107] Furthermore, such as Figure 4 As shown, the insulating component includes a large diameter section 52, a small diameter section 53, and a stepped surface connecting the large diameter section 52 and the small diameter section 53. The large diameter section 52 is fitted onto the outside of the lamp tube, and the stepped surface is a limiting surface 51.

[0108] The stepped structure provides a clear and stable positioning reference for the light-shielding component 3, so that the light-shielding component 3 can be kept in the correct position based on this stable stepped surface, ensuring that light is effectively blocked from leaking from the air inlet 12 and the air outlet 13, thereby enhancing the stability and reliability of the light-shielding effect.

[0109] In other embodiments, the limiting surface 51 can also be the end face of the insulating member away from the lamp tube. In this case, the insulating member can be a structure with a constant diameter. This arrangement simplifies the structure of the insulating member to a certain extent and facilitates its processing and manufacturing.

[0110] Furthermore, such as Figure 5 As shown, the light-shielding member 3 is provided with a clearance hole 31, which allows the small diameter section 53 to pass through.

[0111] With this configuration, on the one hand, the cooperation between the clearance hole 31 and the small diameter section 53 provides a clear positioning point for the light-shielding component 3 during installation. In this way, when the small diameter section 53 passes through the clearance hole 31, the light-shielding component 3 can accurately move along the small diameter section 53 to the position where it contacts the step surface, thereby achieving precise limiting cooperation.

[0112] On the other hand, the presence of the clearance hole 31 makes the installation of the light-shielding component 3 more convenient. Workers can directly align the clearance hole 31 of the light-shielding component 3 with the small-diameter section 53 for installation, without having to painstakingly find the correct installation position. This design reduces uncertainty and error rate during the installation process, making the installation process smoother and more efficient.

[0113] In other embodiments, the light-shielding member 3 can be disposed on one side of the small-diameter section 53. In this case, the clearance hole 31 may not be provided on the light-shielding member 3. This arrangement simplifies the structure of the light-shielding member 3 and facilitates its processing and manufacturing.

[0114] Furthermore, the light-shielding member 3 is provided with a fixing part, which is used to connect with the fixing structure on the hair removal device, and the inner peripheral wall of the clearance hole 31 is spaced apart from the outer peripheral wall of the small diameter section 53.

[0115] This design serves two purposes. First, by connecting the fixing part on the light-shielding component 3 to the fixing structure on the hair removal device, the light-shielding component 3 is easily fixed on the device, ensuring the reliability of its position. Second, by spacing the inner peripheral wall of the clearance hole 31 from the outer peripheral wall of the small-diameter section 53, the light-shielding component 3 can be prevented from exerting force on the lamp tube in the radial direction, thereby reducing the impact of the light-shielding component 3 on the lamp tube. It also facilitates the passage of the small-diameter section 53 through the clearance hole 31.

[0116] In other embodiments, the inner peripheral wall of the clearance hole 31 can also be in surface contact with the outer peripheral wall of the small-diameter section 53. In this case, the light-shielding member 3 does not need to be provided with a fixing part for connecting to the fixing structure on the hair removal device. The light-shielding member 3 can be fixed in position by the surface contact between the inner peripheral wall of the clearance hole 31 and the outer peripheral wall of the small-diameter section 53. This arrangement can simplify the structure of the light-shielding member 3 to a certain extent and facilitate the processing and manufacturing of the light-shielding member 3.

[0117] Furthermore, the distance between the inner peripheral wall of the clearance hole 31 and the outer peripheral wall of the small diameter section 53 is greater than 0.5 mm.

[0118] This design ensures that, on the one hand, the light-shielding member 3 will not exert force on the lamp tube in its radial direction. On the other hand, while facilitating the passage of the small-diameter section 53 through the clearance hole 31, it also ensures the positioning accuracy of the light-shielding member 3 on the insulating member.

[0119] In this embodiment, the distance between the inner peripheral wall of the clearance hole 31 and the outer peripheral wall of the small diameter section 53 can be any value within the range of 0.6mm, 0.7mm or greater than 0.5mm. The size of this distance is set flexibly. Specifically, it can be set according to actual needs. This embodiment does not make specific limitations on this.

[0120] Of course, in other embodiments, the distance between the inner peripheral wall of the clearance hole 31 and the outer peripheral wall of the small diameter section 53 can also be equal to or less than 0.5 mm. With this configuration, since there is a smaller distance between the inner peripheral wall of the clearance hole 31 and the outer peripheral wall of the small diameter section 53, it is beneficial to further improve the positioning accuracy of the light shield 3 in the radial direction of the lamp tube.

[0121] Regarding the structure of the light-shielding element 3, further, as... Figure 5 As shown, the light-shielding member 3 is a light-shielding plate, which includes a large plate portion 32 and a small plate portion 33 connected to the large plate portion 32. The clearance hole 31 is provided in the large plate portion 32, and the small plate portion 33 is the aforementioned fixing part.

[0122] With this configuration, the large plate 32 primarily serves the function of blocking light. Its large area effectively prevents light leakage from the air inlet 12 and air outlet 13, ensuring the safety and aesthetics of the hair removal device. Meanwhile, the small plate 33 serves as a fixing part, specifically used for connecting and fixing with other components. This ensures reliable and stable positioning of the light-blocking component 3, improving the overall stability of the product.

[0123] In addition, the arrangement of the large plate portion 32 and the small plate portion 33, to a certain extent, also helps to reduce the space occupied by the light-shielding component 3 and makes full use of the space inside the hair removal device.

[0124] In other embodiments, the light-shielding plate may consist only of the large plate portion 32, and the large plate portion 32 is also the aforementioned fixing part. This arrangement simplifies the structure of the light-shielding member 3 and facilitates its processing and manufacturing.

[0125] Example 2

[0126] This application also provides a hair removal device, which includes a device body and a power supply assembly (not shown in the figure), such as Figure 1 and Figure 6As shown, the hair removal device body includes a flash component 100 and a housing 200. The flash component 100 has the same structure as any of the flash components 100 in the above embodiments and can bring the same or similar beneficial effects. For details, please refer to the descriptions in the above embodiments; this embodiment will not repeat them here. Figure 6 As shown, a light outlet 2001 is provided on the housing 200, and the flash assembly 100 is disposed inside the housing 200. The light outlet 2001 is used to emit light emitted by the light source 2.

[0127] The power supply unit is connected to the main body of the hair removal device or is located inside the housing 200. The power supply unit is used to supply power to the main body of the hair removal device.

[0128] In this application, on the one hand, the light-shielding member 3 can block light at the air inlet 12 and / or air outlet 13, thereby preventing the light emitted by the light source 2 from leaking out of the air inlet 12 and / or air outlet 13, thus improving the aesthetics of the hair removal device using the flash component 100 and reducing safety risks. On the other hand, the gap 4 between the light-shielding member 3 and the reflector cup 1 can also prevent the air inlet 12 and / or air outlet 13 from being blocked, thereby ensuring that the cooling air can normally enter and / or exit the cooling air duct 11, which is beneficial for the heat dissipation of the light source 2.
