[0002] This application belongs to the field of beauty devices, and particularly relates to skin care devices.
Background Art
[0003] Hair removal devices and photo facial devices are skin care devices commonly used in people's lives. These skin care devices mainly irradiate the user's skin with IPL (intense pulsed light), thereby giving effects such as hair removal and photo rejuvenation to the user's skin.
Summary of the Invention
Problems to be Solved by the Invention
[0004] In related technologies, taking a hair removal device as an example, it is common for a skin care device to be provided with only one tubular light source as an IPL light source, and there is a problem that the skin care effect of the skin care device is low.
Means for Solving the Problems
[0005] Embodiments of this application provide a skin care device, which includes a housing provided with a light exit port, and a light source assembly provided in the housing and including a reflecting member and at least two light sources, wherein at least a part of the reflecting member is located on the side away from the light exit port of the at least two light sources, and reflects a part of the light rays from the at least two light sources to the light exit port. A circuit board assembly provided within the housing, comprising a circuit board, a first conductive bracket, and a second conductive bracket, wherein the first conductive bracket is attached to the circuit board and connected to one end of each of the light sources, and the second conductive bracket is attached to the circuit board and connected to the other end of each of the light sources, so that each of the light sources is supported by the circuit board and electrically connected to the circuit board. [Effects of the Invention]

[0008] Hair removal devices and photofacial devices are skin care devices commonly used in people's lives. These skin care devices primarily use IPL (intense pulsed light) to irradiate the user's skin, thereby providing effects such as hair removal and photorejuvenation.
[0009] In related technologies, taking hair removal devices as an example, skin care devices generally only have one tubular light source as an IPL light source, resulting in a low skin care effect for these devices.
[0010] Therefore, an embodiment of the present application provides a skin care device that can improve the care effect on the skin. The skin care device may be a hair removal device, a beauty device, or the like for performing hair removal, rejuvenation, etc. on the skin. Of course, the skin care device may be a beauty device having functions of hair removal and rejuvenation, but the embodiment of the present application is not limited thereto.
[0011] Please refer to FIGS. 1 and 2. FIG. 1 is a perspective view of a skin care device according to an embodiment of the present application, and FIG. 2 is a schematic configuration diagram of a circuit board assembly and a light source assembly of the skin care device shown in FIG. 1. The skin care device may include a housing 100, a light source assembly 200, and a circuit board assembly 300.
[0012] The housing 100 is provided with a light emission port 11. The light source assembly 200 is provided inside the housing 100. The light source assembly 200 includes a reflecting member 21 and at least two light sources 22. The reflecting member 21 is at least partially located on the side away from the light emission port 11 of the at least two light sources 22 and reflects a part of the light rays from the at least two light sources 22 to the light emission port 11. Then, since the light source assembly 200 in the embodiment of the present application includes a plurality of light sources 22, the light source assembly 200 can perform skin care with a larger maximum power and improve the care effect.
[0013] The circuit board assembly 300 is provided inside the housing 100. The circuit board assembly 300 includes a circuit board 31, a first conductive bracket 32, and a second conductive bracket 33. The first conductive bracket 32 is attached to the circuit board 31 and connected to one end of each light source 22, and the second conductive bracket 33 is attached to the circuit board 31 and connected to the other end of each light source 22 to support each light source 22 on the circuit board 31 and electrically connect it to the circuit board 31.
[0014] The end connected to the first conductive bracket 32 of the light source 22 may be the positive electrode, and the end connected to the second conductive bracket 33 of the light source 22 may be the negative electrode. Alternatively, the end connected to the first conductive bracket 32 of the light source 22 may be the negative electrode, and the end connected to the second conductive bracket 33 of the light source 22 may be the positive electrode. The embodiments of the present application are not limited thereto.
[0015] In this way, by electrically connecting the positive electrodes of all the light sources 22 to the circuit board 31 with the same conductive bracket and electrically connecting the negative electrodes of all the light sources 22 to the circuit board 31 with the same conductive bracket, the current transmission between the circuit board 31 and all the light sources 22 becomes more consistent, improving the emission consistency of all the light sources 22, and ultimately improving the care effect of the skin care device.
[0016] For example, since the emission of all the light sources 22 is more consistent, the luminance at each position of the light emission port 11 can be made more uniform, thereby avoiding insufficient hair removal or insufficient rejuvenation effect due to low luminance at some positions in the light emission port 11.
[0017] Hereinafter, the technical solutions implemented in the present application will be interpreted and described in relation to the first conductive bracket 32 and the second conductive bracket 33 respectively.
[0018] The first conductive bracket 32 may be a conductive metal material, such as copper, aluminum, silver, gold, nickel, etc. The first conductive bracket 32 may also be other non-metal conductive materials such as graphite, conductive rubber, etc. The embodiments of the present application are not limited thereto.
[0019] Referring again to Figures 3 to 5, Figure 3 is a second schematic configuration diagram of the first conductive bracket in the light source assembly shown in Figure 2, Figure 4 is a second schematic configuration diagram of the first conductive bracket in the light source assembly shown in Figure 2, and Figure 5 is a third schematic configuration diagram of the first conductive bracket in the light source assembly shown in Figure 2. The first conductive bracket 32 may comprise a first main body 321 and a plurality of first connection parts 322. The first main body 321 is attached to the circuit board 31 and extends from the circuit board 31 toward at least two light sources 22. Each first connection part 322 is provided corresponding to one light source 22, with one end of each first connection part 322 connected to the first main body 321 and the other end connected to one end of the corresponding light source 22, thereby electrically connecting one end of each light source 22 to the circuit board 31 via the first conductive bracket 32.
[0020] The first main body portion 321 may be straight, arc-shaped, bent, or have other irregular shapes, and is not limited thereto in the embodiments of the present application.
[0021] In some embodiments, the first main body 321 may include a first mounting portion 3211 and a first extension portion 3212. The first mounting portion 3211 is connected to and fixed to the circuit board 31. The first extension portion 3212 is connected to the end of the first mounting portion 3211 closest to the light output 11 and extends from the side of the first mounting portion 3211 away from the circuit board 31 toward at least two light sources 22, and the first extension portion 3212 is connected to each first connection portion 322.
[0022] Therefore, it can be understood that by making the portion of the first main body 321 that connects to the circuit board 31 wider or larger, thereby increasing the connection area between the first conductive bracket 32 and the circuit board 31, the stability of the connection of the first conductive bracket 32 can be improved, and the light source 22 can also be supported more stably.
[0023] When the position of the light source 22 does not change, the distance from the first extension portion 3212 to the light output port 11 also does not change. In this case, compared to connecting the first extension portion 3212 to the end of the first mounting portion 3211 that is far from the light output port 11, this embodiment connects the first extension portion 3212 to the side of the first mounting portion 3211 that is closer to the light output port 11, thereby increasing the distance of the first mounting portion 3211 from the light output port 11 and avoiding the risk of electrical leakage due to the first mounting portion 3211 being too close to the light output port 11.
[0024] The first mounting portion 3211 has a free end that is away from the circuit board 31, and in this application, "the first extension portion 3212 is connected to the end of the first mounting portion 3211 that is closer to the light output port 11" means that the first extension portion 3212 is connected to the free end of the first mounting portion 3211 and is offset at this free end toward the light output port 11.
[0025] Furthermore, the end of the first mounting portion 3211 closest to the light output port 11 means the portion between the central portion of the first mounting portion 3211 and the end face of the first mounting portion 3211 facing the light output port 11. In the embodiment of the present application, "the first extension portion 3212 is connected to the end of the first mounting portion 3211 closest to the light output port 11" means that the first extension portion 3212 is connected to any position between the central portion of the first mounting portion 3211 and the end face of the first mounting portion 3211 facing the light output port 11.
[0026] It is connected to the free end of the first mounting portion 3211, and this means that it is offset in a direction closer to the light emission port 11 at this free end.
[0027] In some embodiments, a plurality of first fixing legs 324 are provided at the end of the first conductive bracket 32 closest to the circuit board 31. Each of the plurality of first fixing legs 324 is welded to the circuit board 31, and the plurality of first fixing legs 324 can improve the stability and reliability of the connection between the first conductive bracket 32 and the circuit board 31.
[0028] For example, the number of first fixed legs 324 may be two, three, four, or five.
[0029] Furthermore, any of the first fixed legs 324 may be welded to the circuit board 31 to form a physical connection, or they may be welded to the circuit board 31 to form an electrical connection configured to transmit current, and it can be understood that the embodiments of the present application are not limited thereto.
[0030] For example, if we take the case where there are three first fixed legs 324, all three first fixed legs 324 may be welded and fixed to the circuit board 31 and electrically connected.
[0031] It can also be understood that all of the multiple first fixed legs 324 are provided on the first mounting portion 3211 described above. For example, multiple first fixed legs 324 are provided side by side on the first mounting portion 3211 in a direction away from the light emission port 11.
[0032] In some embodiments, by having the same thickness at each point of the first main body 321, the resistance at each point of the first main body 321 becomes substantially the same, so that the current transmission between the circuit board 31 and each light source 22 becomes more consistent, and the brightness at each position in the light output opening 11 becomes more uniform.
[0033] Of course, in some other embodiments, the thickness of the first main body 321 may differ at different points, and the embodiments of the present application are not limited thereto.
[0034] In some embodiments, having the same width at each point of the first main body 321 results in substantially the same resistance at each point of the first main body 321, which leads to more consistent current transmission between the circuit board 31 and each light source 22, and more uniform brightness at each position in the light output opening 11.
[0035] Of course, in some other embodiments, the width of the first main body 321 may differ at different points, and the embodiments of the present application are not limited thereto.
[0036] At each location of the first main body 321, only the width may be the same, or only the thickness may be the same, and the embodiment of the present application is not limited thereto. Of course, the width and thickness at each location of the first main body 321 may both be the same so that the electrical resistance at each location of the first main body 321 is more evenly matched.
[0037] In some embodiments, all first connection portions 322 may be located on the side of the first main body 321 closer to the light output port 11, or on the side of the first main body 321 further away from the light output port 11, but the embodiments of the present application are not limited thereto.
[0038] In some embodiments, having all the first connection points 322 of the same length results in substantially the same resistance at each first connection point 322, which leads to more consistent current transfer between the circuit board 31 and each light source 22, thereby resulting in more uniform brightness at each position in the light output opening 11.
[0039] Of course, in some other embodiments, only some of the first connecting portions 322 may be the same length, or all of the first connecting portions 322 may be different lengths, and the embodiments of the present application are not limited thereto.
[0040] In some embodiments, having the same thickness for all first connection portions 322 results in substantially the same resistance at each first connection portion 322, leading to more consistent current transfer between the circuit board 31 and each light source 22, thereby resulting in more uniform brightness at each position in the light output port 11.
[0041] Of course, in some other embodiments, only some of the first connecting portions 322 may have the same thickness, or all of the first connecting portions 322 may have different thicknesses, and the embodiments of the present application are not limited thereto.
[0042] In some embodiments, having the same width for all first connection points 322 results in substantially the same resistance at each first connection point 322, leading to more consistent current transfer between the circuit board 31 and each light source 22, thereby resulting in more uniform brightness at each position in the light output opening 11.
[0043] Of course, in some other embodiments, only the widths of some of the first connecting portions 322 may be the same, or the thicknesses of all of the first connecting portions 322 may be different, and the embodiments of the present application are not limited thereto.
[0044] All first connecting portions 322 may have the same width, the same thickness, the same length, the same thickness and width, or the same thickness and length, and are not limited to these embodiments of the present application. Of course, all first connecting portions 322 may have the same length, thickness and width, or all first connecting portions 322 may have the same shape and size, thereby resulting in more uniform resistance at each first connecting portion 322.
[0045] Furthermore, it can be understood that the fact that the width and thickness of the first main body 321 are the same at each point, and that the length, width, and thickness of all the first connection parts 322 are also the same, leads to a more consistent current transmission between the circuit board 31 and all the light sources 22.
[0046] Of course, at least one of the width and thickness of the first main body 321 may be the same at each location, and one or more of the lengths, widths, and thicknesses of all the first connecting parts 322 may be the same. Alternatively, the width and thickness of the first main body 321 may differ at each location, and one or more of the lengths, widths, and thicknesses of all the first connecting parts 322 may be the same. Alternatively, the width and thickness of the first main body 321 may differ at each location, and the lengths, widths, and thicknesses of all the first connecting parts 322 may be different, and the embodiments of this application are not limited thereto.
[0047] In some embodiments, the first conductive bracket 32 may be provided with at least two first locking grooves 323, and one end of each light source 22 is locked into one of the first locking grooves 323.
[0048] After one end of the light source 22 is locked into the corresponding first locking groove 323, the light source 22 and the first conductive bracket 32 may be reinforced by welding, or they may not be welded to facilitate replacement, but the embodiment of the present application is not limited to this.
[0049] Considering that the first conductive bracket 32 has a plurality of first connecting portions 322 as described above, each first connecting portion 322 may have a first locking groove 323 at the end away from the first main body portion 321.
[0050] In some embodiments, the second conductive bracket 33 may be made of a conductive metallic material such as copper, aluminum, silver, gold, or nickel. The second conductive bracket 33 may also be made of other non-metallic conductive materials such as graphite or conductive rubber, and is not limited to these in the embodiments of the present application.
[0051] Continuing with Figure 6, Figure 6 is a second schematic configuration diagram of the second conductive bracket in the light source assembly shown in Figure 2. The second conductive bracket 33 may comprise a second main body 331 and a plurality of second connection parts 332. The second main body 331 is mounted on the circuit board 31 and extends from the circuit board 31 toward at least two light sources 22. Each second connection part 332 is provided corresponding to one light source 22, with one end of each second connection part 332 connected to the second main body 331 and the other end connected to one end of the corresponding light source 22, thereby electrically connecting one end of each light source 22 to the circuit board 31 by the second conductive bracket 33.
[0052] The second main body portion 331 may be straight, arc-shaped, bent, or have other irregular shapes, and is not limited thereto in the embodiments of the present application.
[0053] In some embodiments, the second main body 331 may include a second mounting portion 3311 and a second extension portion 3312. The second mounting portion 3311 is connected to and fixed to the circuit board 31. The second extension portion 3312 is connected to the end of the second mounting portion 3311 closest to the light output port 11 and extends from the side of the second mounting portion 3311 away from the circuit board 31 toward at least two light sources 22, and the second extension portion 3312 is connected to each of the first connection portions 322.
[0054] Therefore, it can be understood that by making the portion of the second main body 331 that connects to the circuit board 31 wider or larger, the connection area between the second conductive bracket 33 and the circuit board 31 can be increased, thereby improving the stability of the connection of the second conductive bracket 33 and enabling more stable support of the light source 22.
[0055] When the position of the light source 22 remains unchanged, the distance from the second extension 3312 to the light output port 11 also remains unchanged. In this case, compared to connecting the second extension 3312 to the end of the second mounting portion 3311 that is far from the light output port 11, the embodiment of the present invention connects the second extension 3312 to the side of the second mounting portion 3311 that is closer to the light output port 11, thereby increasing the distance of the second mounting portion 3311 from the light output port 11 and avoiding the risk of electrical leakage due to the second mounting portion 3311 being too close to the light output port 11.
[0056] The second mounting portion 3311 has a free end that is away from the circuit board 31, and in the embodiment of the present application, "the second extension portion 3312 is connected to the end of the second mounting portion 3311 that is closer to the light output port 11" means that the second extension portion 3312 is connected to the free end of the second mounting portion 3311 and is offset at this free end toward the light output port 11.
[0057] Furthermore, the end of the second mounting portion 3311 closest to the light output port 11 means the portion between the central portion of the second mounting portion 3311 and the end face of the second mounting portion 3311 facing the light output port 11. In the embodiment of the present application, "the second extension portion 3312 is connected to the end of the second mounting portion 3311 closest to the light output port 11" means that the second extension portion 3312 is connected to any position between the central portion of the second mounting portion 3311 and the end face of the second mounting portion 3311 facing the light output port 11.
[0058] Of course, in some other embodiments, the second extension 3312 may be connected to the end of the second mounting portion 3311 away from the light output port 11, and the embodiments of the present application are not limited thereto.
[0059] In some embodiments, a plurality of second fixing legs 334 are provided at the end of the second conductive bracket 33 closest to the circuit board 31. Each of the plurality of second fixing legs 334 is welded to the circuit board 31, and the plurality of second fixing legs 334 can improve the stability and reliability of the connection between the second conductive bracket 33 and the circuit board 31.
[0060] For example, the number of second fixed legs 334 may be two, three, four, or five.
[0061] Furthermore, any of the second fixing legs 334 may be welded to the circuit board 31 to form a physical connection, or they may be welded to the circuit board 31 to form an electrical connection configured to transmit current, and it can be understood that the embodiments of the present application are not limited thereto.
[0062] For example, if we take the case where there are three second fixing legs 334, all three second fixing legs 334 may be welded and fixed to the circuit board 31 and electrically connected.
[0063] Furthermore, it can be understood that all of the multiple second fixing legs 334 are provided on the second mounting portion 3311 described above. For example, multiple second fixing legs 334 are provided side by side on the second mounting portion 3311 in a direction away from the light emission port 11.
[0064] In some embodiments, the thickness of the second main body 331 is the same at each point, which results in the resistance at each point of the second main body 331 being approximately the same, leading to more consistent current transmission between the circuit board 31 and each light source 22, and thus more uniform brightness at each position in the light output opening 11.
[0065] Of course, in some other embodiments, the thickness of the second main body 331 may differ at different points, and the embodiments of the present application are not limited thereto.
[0066] In some embodiments, the width of the second main body 331 is the same at each point, which results in the resistance at each point of the second main body 331 being approximately the same, leading to more consistent current transmission between the circuit board 31 and each light source 22, and thus more uniform brightness at each position in the light output opening 11.
[0067] Of course, in some other embodiments, the width of the second main body 331 may differ at different points, and the embodiments of the present application are not limited thereto.
[0068] At each location of the second main body 331, only the width may be the same, or only the thickness may be the same, and the embodiment of the present application is not limited to this. Of course, the width and thickness at each location of the second main body 331 may both be the same in order to better match the electrical resistance at each location of the second main body 331.
[0069] In some embodiments, all second connection portions 332 may be located on the side of the second main body 331 closer to the light output port 11, or on the side of the second main body 331 further away from the light output port 11, but the embodiments of the present application are not limited thereto.
[0070] In some embodiments, having all the second connection points 332 of the same length results in substantially the same resistance at each second connection point 332, leading to more consistent current transfer between the circuit board 31 and each light source 22, thereby resulting in more uniform brightness at each position in the light output port 11.
[0071] Of course, in some other embodiments, only some of the second connecting portions 332 may be the same length, or all of the second connecting portions 332 may be different lengths, and the embodiments of the present application are not limited thereto.
[0072] In some embodiments, having the same thickness for all second connection portions 332 results in substantially the same resistance at each second connection portion 332, leading to more consistent current transfer between the circuit board 31 and each light source 22, thereby resulting in more uniform brightness at each position in the light output port 11.
[0073] Of course, in some other embodiments, only some of the second connecting portions 332 may have the same thickness, or all of the second connecting portions 332 may have different thicknesses, and the embodiments of the present application are not limited thereto.
[0074] In some embodiments, having the same width for all second connection points 332 results in substantially the same resistance at each second connection point 332, leading to more consistent current transfer between the circuit board 31 and each light source 22, thereby resulting in more uniform brightness at each position in the light output opening 11.
[0075] Of course, in some other embodiments, only the widths of some of the second connecting portions 332 may be the same, or the thicknesses of all of the second connecting portions 332 may be different, and the embodiments of the present application are not limited thereto.

Of course, all second connectors 332 may have the same length, thickness and width, or all second connectors 332 may have the same shape and size, thereby resulting in more uniform resistance at each second connector 332.
[0077] Furthermore, it can be understood that the fact that the width and thickness of the second main body 331 are the same at each point, and that the length, width, and thickness of all the second connection parts 332 are also the same, leads to a more consistent current transmission between the circuit board 31 and all the light sources 22.
[0078] Of course, the width and thickness of each part of the second main body 331 may be the same, and one or more of the lengths, widths, and thicknesses of all the second connecting parts 332 may be the same. Alternatively, the width and thickness of each part of the second main body 331 may differ, and one or more of the lengths, widths, and thicknesses of all the second connecting parts 332 may be the same. Alternatively, the width and thickness of each part of the second main body 331 may differ, and the lengths, widths, and thicknesses of all the second connecting parts 332 may differ, and the embodiments of this application are not limited thereto.

[0080] After one end of the light source 22 is locked into the corresponding second locking groove 333, the light source 22 and the second conductive bracket 33 may be reinforced by welding, or they may not be welded to facilitate replacement, but the embodiment of the present application is not limited to this.
[0081] As described above, considering that the second conductive bracket 33 has a plurality of second connecting portions 332, each second connecting portion 332 may have a second locking groove 333 at the end away from the second main body portion 331.
[0082] The first conductive bracket 32 and the second conductive bracket 33 will be described below with reference to the at least two light sources 22 and reflective members 21 mentioned above.
[0083] Continuing to refer to Figure 7, Figure 7 is a schematic diagram of the single-position distribution of light sources in the skin care device shown in Figure 1. The multiple light sources 22 may be parallel to each other. For example, each light source 22 may include a tubular light source such as a hernia lamp, in which case the longitudinal directions of each tubular light source may be parallel to each other.
[0084] Compared to a configuration where multiple light sources 22 are scattered and arranged haphazardly, in the embodiment of the present invention, the multiple light sources 22 are arranged parallel to each other, which makes the overall emission of light from the multiple light sources 22 more uniform. Therefore, if the skin care device is a hair removal device or a skin beautification device, the brightness of the light at each position in the light emission port 11 becomes more uniform, avoiding insufficient hair removal or rejuvenation in some areas of the skin due to weak brightness, and enhancing the effect of hair removal or rejuvenation.
[0085] In some embodiments, the distance from multiple light sources 22 to the light output port 11 may be the same. The light intensity of the light rays emitted from the light sources 22 decreases as the radiation distance increases, but in the embodiments of the present application, by making the distance from multiple light sources 22 to the light output port 11 the same, the brightness of the light rays at each position in the light output port 11 can be made more uniform. Therefore, taking the skin care device as an example of a hair removal device or a skin beautification device, the brightness of the light at each position in the light output port 11 becomes more uniform, which can avoid insufficient hair removal or rejuvenation in some areas of the skin due to weak brightness, and can enhance the effect of hair removal or rejuvenation.
[0086] Furthermore, the multiple light sources 22 may be parallel to each other and the distance from each light source 22 to the light output port 11 may be different, or the multiple light sources 22 may not be parallel to each other and the distance from each light source 22 to the light output port 11 may be the same, or the multiple light sources 22 may be parallel to each other and the distance from each light source 22 to the light output port 11 may be the same, and the embodiment of the present application is not limited to these.
[0087] Alternatively, continuing to refer to Figure 8, which is a schematic diagram of another positional distribution of light sources in the skin care device shown in Figure 1. The distances from different light sources 22 to the light output port 11 may differ.
[0088] For example, at least two light sources 22 include a first light source 221 and a second light source 222. The distance from the first light source 221 to the light output port 11 is greater than the distance from the second light source 222 to the light output port 11. In other words, the first light source 221 is closer to the light output port 11. Therefore, the power of the first light source 221 may be greater than the power of the second light source 222. This results in a smaller or equal difference between the intensity of light illuminating the light output port 11 from the first light source 221 and the intensity of light illuminating the light output port 11 from the second light source 222, making the brightness at each position of the light output port 11 more uniform.
[0089] Here, the number of light sources 22 may be 3, 4, 5, or 6, and the first light source 221 and the second light source 222 may be any two of the multiple light sources 22; the embodiment of the present application is not limited to this.
[0090] In the following section, we will continue to explain the positional arrangement of the multiple light sources 22 in relation to the reflective member 21, using examples.
[0091] Continuing to refer to Figure 9, Figure 9 is a first schematic configuration diagram of the reflective member of the skin care device shown in Figure 1. The reflective member 21 may be provided with a reflective chamber that opens to the light emission port 11, and at least two light sources 22 are mounted inside the reflective chamber. Therefore, depending on the reflective chamber, it is possible to reflect light rays emitted from the light sources 22 at a 360° angle and focus them toward the light emission port 11, thereby improving the light emission rate of the light source assembly 200 or improving the brightness at the light emission port 11.
[0092] The light emission port 11 may be located on one side of the at least two light sources 22 in the first direction H1, and the at least two light sources 22 are spaced apart in the second direction H2 perpendicular to the first direction H1.
[0093] The shape of the skin care device can vary, for example, it may be hair dryer-type, elongated, flattened small rectangle, circular, or elliptical. However, (omitted) in the case of an elongated skin care device, the first direction H1 may be the length direction of the skin care device and the second direction H2 may be the thickness direction of the skin care device, or the first direction H1 may be the length direction of the skin care device and the second direction H2 may be the width direction of the skin care device, and the embodiment of this application is not limited to this.
[0094] In the following, the present invention will be described primarily using a long, rectangular skin care device as an example. Specifically, in the embodiment of the present invention, the first direction H1 is the length direction of the skin care device, and the second direction H2 is the thickness direction of the skin care device. The technical measures of the embodiment of the present invention will be interpreted and explained using this example.
[0095] In some embodiments, along a second direction H2, the reflection chamber is symmetrical with respect to a first axis L1 parallel to the first direction H1, and all light sources 22 are arranged symmetrically with respect to the first axis L1. Thus, because the reflection chamber is symmetrical with respect to the first axis L1, arranging the light sources 22 symmetrically with respect to the first axis L1 makes the light rays reflected by the inner wall of the reflection chamber from multiple light sources 22 more uniform.
[0096] In some embodiments, the reflective member 21 may have a first linear section 211, a third connecting section 212, and a second linear section 213 that are connected in sequence. The first linear section 211 and the second linear section 213 are spaced apart in the second direction H2, and the third connecting section 212 is directed toward the light output port 11, so that the first linear section 211, the third connecting section 212, and the second linear section 213 surround a reflective chamber whose opening faces the light output port 11. As a result, a portion of the light rays emitted by the light source 22 can be emitted directly toward the light output port 11 from between the first flat section 211 and the second flat section 213, and another portion of the light rays emitted by the light source 22 can be reflected by one or more of the third connecting section 212, the first flat section 211, and the second flat section 213 and emitted toward the light output port 11.
[0097] In some embodiments, the third connecting portion 212 includes an arcuate surface. One circumferential end of the arcuate surface is connected to the first flat portion 211. The other circumferential end of the arcuate surface is connected to the second flat portion 213. Alternatively, it can be easily understood that the first straight portion 211, the second straight portion 213, and the third connecting portion 212 form a U-shaped structure, with the third connecting portion 212 located in the middle of the U-shaped structure. As a result, the third connecting portion 212 is parabolic, which allows it to effectively concentrate the light rays emitted by the multiple light sources 22, thereby improving the brightness at the light output port 11 and making the brightness at each point in the light output port 11 more uniform.
[0098] Optionally, referring again to Figure 10, which is a second schematic configuration diagram of the reflective member of the skin care device shown in Figure 1. The third connection portion 212 may have at least two light-gathering surfaces 2121, each of which corresponds to one light source 22. This allows each light-gathering surface 2121 to provide a good light-gathering effect to the corresponding light source 22. The embodiments of the present application are not limited thereto.
[0099] In some embodiments, the third connection portion 212 is provided surrounding at least two light sources 22. The end of the third connection portion 212 connected to the first flat portion 211 and the end of the third connection portion 212 connected to the second flat portion 213 both protrude beyond the side of at least two light sources 22 closer to the light output ports 11.
[0100] Alternatively, it can be easily understood that in the first direction H1, all of the multiple light sources 22 are located inside the third connection section 212. This allows the third connection section 212 to provide a good light-gathering effect with the multiple light sources 22, thereby improving the uniformity of brightness at each position of the light output opening 11.
[0101] The light source 22 may be located entirely within the space formed by the third connecting portion 212, or only partially within the space formed by the third connecting portion 212. This is not limited to the embodiments of the present application.
[0102] For example, referring to Figure 11, which is a schematic diagram of the positional relationship between the light source and the reflective member in the longitudinal direction in the skin care device shown in Figure 1. The light source 22 is a tubular light source, and the longitudinal directions of the tubular light source, the first direction H1 and the second direction H2 are perpendicular to each other. At least one end of the tubular light source in the longitudinal direction is located outside the third connection portion 212. In the longitudinal direction of the tubular light source, the length of the portion of each end of the tubular light source located outside the third connection portion 212 is 1 / 5 or less of the total length of the tubular light source.
[0103] For example, in the longitudinal direction of the tubular light source, the length located outside the third connection portion 212 at each end of the tubular light source may be 1 / 5, 1 / 6, 1 / 7, 1 / 8, etc., of the total length of the tubular light source, but the embodiment of the present application is not limited thereto.
[0104] The longitudinal direction of the tubular light source may be the third direction H3. Therefore, (omitted) taking the elongated skin care device as an example, the longitudinal direction of the tubular light source, i.e., the third direction H3, is the width direction of the skin care device.
[0105] Normally, when a tubular light source is in operation, the brightness is low at both ends in the length direction. Therefore, if the low-brightness portion of the tubular light source is placed outside the reflective member 21, the light emitted by the tubular light source will not be excessively wasted. Furthermore, the pins of the tubular light source can be placed outside the third connection part 212, which facilitates connection with the conductive bracket and reduces the difficulty of assembling and manufacturing the skin care device.
[0106] Figures 11 and 12 are shown in relation to each other. Figure 12 is a schematic diagram of another positional relationship in the longitudinal direction between the light source and the reflective member in the skin care device shown in Figure 1. In some embodiments, one end of each light source 22 may be located outside the reflective chamber, such that the first conductive bracket 32 is located outside the reflective chamber and connected to one end of each light source 22. Alternatively, one end of each light source 22 may be located inside the reflective chamber, such that the first conductive bracket 32 penetrates the reflective chamber and is connected to one end of each light source 22.
[0107] Similarly, the other end of each light source 22 is located outside the reflection chamber, and the second conductive bracket 33 is located outside the reflection chamber and connected to the other end of each light source 22. Alternatively, the other end of each light source 22 is located inside the reflection chamber, and the second conductive bracket 33 penetrates the reflection chamber and is connected to the other end of each light source 22. The embodiments of the present application are not limited to this.
[0108] Continuing to refer to Figure 13, Figure 13 is a schematic structural diagram of the light source assembly and circuit board assembly shown in Figure 2 after the isolation members have been attached. As an example, the light source 22 may be a tubular light source. Each light source 22 is provided close to the inner wall of the reflection chamber, and the reflection member 21 is electrically connected to the circuit board 31, so that the circuit board 31 can excite the tubular light source via the reflection member 21. The skin care device may further include an isolation member 34 that covers the outside of at least two light sources 22. The isolation member 34 separates at least one of the first conductive bracket 32 and the second conductive bracket 33 from the reflection member 21, thereby preventing short circuits and leakage currents caused by contact between the reflection member 21 and the conductive bracket.
[0109] Of course, the light source 22 is a tubular light source, each light source 22 is provided close to the inner wall of the reflection chamber, the reflective member 21 is electrically connected to the circuit board 31, and the circuit board 31 can excite the tubular light source via the reflective member 21. The skin care device may further include an isolation member 34 that covers at least one of the first conductive bracket 32 and the second conductive bracket 33. The isolation member 34 separates at least one of the first conductive bracket 32 and the second conductive bracket 33 from the reflective member 21, thereby preventing short circuits and leakage currents caused by contact between the reflective member 21 and the conductive bracket.
[0110] In some embodiments, the light source 22 is still associated with being a tubular light source, and at least one end of the tubular light source in the longitudinal direction is located outside the third connection portion 212 or the reflector member 21, the isolation member 34 may be placed over the portion of the tubular light source located outside the third connection portion 212, or the isolation member 34 may be placed over the outside of the conductive bracket.
[0111] The following explanation will include examples illustrating that the conductive bracket may be provided outside the reflection chamber or may penetrate the reflective member 21.
[0112] In some embodiments, at least one end of the light source 22 is located outside the reflection chamber and connected to a corresponding first conductive bracket 32 or second conductive bracket 33. The skin care device may further include an isolation member 34 that covers the light source 22 and is located between the reflective member 21 and the first conductive bracket 32 or second conductive bracket 33 so as to separate the reflective member 21 from the conductive bracket.
[0113] In some embodiments, the reflective member 21 is provided with a through hole communicating with a reflection chamber, and at least one of the first conductive bracket 32 and the second conductive bracket 33 is connected to the light source 22 by penetrating the reflection chamber through the through hole, and the skin care device further comprises an isolation member 34, the isolation member 34 of which at least a portion is located within the through hole and separates the reflective member 21 from the conductive bracket by separating the inner wall of the through hole from the corresponding first conductive bracket 32 and / or second conductive bracket 33.
[0114] For example, continuing to consider the light source 22 as a tubular light source, if the first conductive bracket 32 and / or the second conductive bracket 33 penetrate the reflective member 21 and enter the reflective chamber to support the light source 22, when they protrude into the reflective chamber, an isolation member 34 is placed over the first conductive bracket 32 and / or the second conductive bracket 33, and at least a portion of the isolation member 34 is located inside the through-hole of the reflective member 21.
[0115] Thus, the isolation member 34 is configured to separate the reflective member 21 from the first conductive bracket 32 and / or the second conductive bracket 33 in order to provide safety during use by preventing leakage current from the reflective member 21 to the first conductive bracket 32 and / or the second conductive bracket 33, and also to prevent leakage current from the first conductive bracket 32 and / or the second conductive bracket 33 to the reflective member 21.
[0116] The fact that the isolation member 34 is placed over the outside of at least two light sources 22 has at least the following two implications:
[0117] The same end of multiple tubular light sources may all pass through the same isolation member 34. For example, among multiple tubular light sources that fit into the same isolation member 34, different tubular light sources may pass through different isolation holes in the isolation member 34 and be isolated. Alternatively, different tubular light sources may be separated by different isolation members 34, but the embodiments of this application are not limited to this.
[0118] Furthermore, it is understood that the isolation member 34 may be made of an insulating material. For example, the isolation member 34 may be made of rubber, and of course, the isolation member may be made of other insulating materials such as ceramics, and is not limited to these in the embodiments of the present application.
[0119] In some embodiments, the light source 22 may be in contact with the reflective member 21, for example, the third connecting portion 212 of the reflective member 21. This reduces the gap between the light source 22 and the reflective member 21. Furthermore, the entire light source assembly 200 becomes more compact, facilitating miniaturization of the skin care device.
[0120] In relation to the fact that the light source 22 described above may be a tubular light source, if the size of the space within the third connection part 212 is constant, the light source 22 can directly contact the third connection part 212, thereby increasing the distance between the first light source 221 and the second light source 222, reducing the probability of interference between the first light source 221 and the second light source 222, and improving the reliability of the light source 22. In other words, it becomes easier to arrange the first light source 221 and the second light source 222 etc. within the reflective member 21 without increasing the size or decreasing the width of the reflective member 21, and miniaturization can be achieved.
[0121] For example, if at least two light sources 22 have a first light source 221 and a second light source 222, and the third connection portion 212 of the reflecting member 21 has an arcuate surface, the first light source 221 and the second light source 222 may be provided at the two trisecting points of the third connection portion 212, respectively.
[0122] If the number of light sources 22 is greater than three, multiple light sources 22 can be arranged along the inner wall surface of the reflection chamber.
[0123] For example, if there are three light sources 22 and the third connection portion 212 of the reflecting member 21 has an arcuate surface, the three light sources 22 are located at three equally spaced points on the third connection portion 212. If there are four light sources 22 and the third connection portion 212 of the reflecting member 21 has an arcuate surface, the four light sources 22 are located at four equally spaced points on the third connection portion 212.
[0124] The above describes some examples of the light source assembly 200 and conductive bracket in the embodiments of the present application, and the following will continue to describe some other configurations in the embodiments of the present application with further examples.
[0125] Referring again to Figures 14 and 15, Figure 14 is a top view of the skin care device shown in Figure 1, and Figure 15 is a cross-sectional view of the skin care device shown in Figure 14 in direction AA. In some embodiments, the light output port 11 is located on one side of a first direction H1 with respect to at least two light sources 22, and the circuit board 31 is located on one side of a second direction H2 perpendicular to the first direction H1 with respect to the skin care device. The skin care device further comprises a heat dissipation assembly 400 provided within the housing 100, at least a portion of which is located on the side of the reflective member 21 away from the light output port 11.
[0126] Since the light source 22 is the main heat source of the skin care device, it is understood that as the number of light sources 22 increases, the heat in the light source assembly 200 increases accordingly. Compared to arranging the circuit board 31 between the side of the reflective member 21 away from the light output port 11 and the heat dissipation assembly 400, in the embodiment of the present application, by arranging the circuit board 31 on the other side of the light source 22, the distance between the heat dissipation assembly 400 and the light source assembly 200 can be brought closer, shortening the heat dissipation path and further enhancing the heat dissipation effect to the light source assembly 200 equipped with multiple light sources 22. As a result, the light source assembly 200 is prevented from overheating and malfunctioning due to the operation of multiple light sources 22, and consequently the skin care effect of the skin care device is improved.
[0127] The skin care device is configured to apply a cold compress to the skin and further comprises a cold compress assembly 500 attached to the housing 100.
[0128] For example, the cold compress assembly 500 may include a light guide member 51 and a cooling sheet 52. The light guide member 51 is provided at the light outlet 11 so as to transmit light rays emitted from the light source 22. The cooling sheet 52 is thermally conductively connected to the light guide member 51. For example, the cooling sheet 52 may be directly attached to the light guide member 51 or attached to the light guide member 51 by a thermal conductive medium such as thermally conductive silicone grease.
[0129] Furthermore, the light guide member 51 is cooled by the cooling sheet 52, and the cooled light guide member 51 is exposed from the light emission port 11 and can come into contact with the skin. Therefore, the light guide member 51 not only transmits light rays from the light source 22 to care for the user's skin, but is also cooled by the cooling sheet 52 and can provide the user with a cold compress.
[0130] Of course, it is understood that the light source assembly 200 is the main heat source of the skin care device, and the light guide member 51 is located on the light-emitting side of the light source assembly 200, and the cooling sheet 52 cools the light guide member 51, thereby providing a certain degree of heat dissipation effect to the light source assembly 200 as well, and thus preventing damage caused by the light source assembly 200 becoming excessively hot.
[0131] The cooling sheet 52, also known as a semiconductor cooling sheet, utilizes the Peltier effect of semiconductor materials. When a direct current passes through a galvanic couple, which consists of two different semiconductor materials connected in series, heat is absorbed and released at both ends of the galvanic couple, thereby achieving the purpose of cooling.
[0132] The light guide member 51 may be made of sapphire material or other light guide material, and is not limited to this in the embodiments of the present application.
[0133] The skin care device may further include a filter 600 provided between the light source assembly 200 and the light guide member 51, which filters the light rays irradiated from the light source assembly 200 to the light guide member 51.
[0134] For example, filter 600 may be configured to transmit light rays with wavelengths of 420nm to 1200nm, thereby forming IPL (intense pulsed light) rays that are irradiated onto the user's skin. On the other hand, in actual use, the wavelength of light required for hair removal may be 420nm to 1200nm, while the wavelength of light required for skin beautification may be 600nm to 1200nm. In this case, the skin care device can simultaneously have three functions: cold compress, skin rejuvenation, and hair removal.
[0135] Hereinafter, the technical measures of the embodiments of the present application will be described with further examples, relating to the heat dissipation assembly 400 of the embodiments of the present application.
[0136] A heat dissipation passage 12 may be provided inside the housing 100. The heat dissipation assembly 400 includes a fan 41 that drives the air in the heat dissipation passage 12 to flow in a predetermined direction to dissipate heat from the light source assembly 200 and / or the cold damp cloth assembly 500.
[0137] In other words, the fan 41 may be configured to dissipate heat only from the light source assembly 200, or to dissipate heat only from the cold compress assembly 500, or to dissipate heat from both the light source assembly 200 and the cold compress assembly 500 simultaneously, but the embodiments of the present application are not limited thereto.
[0138] For example, if the heat dissipation assembly 400 is configured to dissipate heat from the cooling sheet assembly 500, the heat dissipation assembly 400 may further include a heat conductive member 42 and a heat dissipation fin 43. The heat conductive member 42 has a first end and a second end. The first end is thermally conductively connected to the cooling sheet 52, for example, by being directly attached to the cooling sheet 52 or by being attached to the cooling sheet 52 with a heat conductive medium such as thermally conductive silicone grease. The heat dissipation fin 43 is thermally conductively connected to the second end, for example, by being directly attached to the cooling sheet 52 or by being attached to the cooling sheet 52 with a heat conductive medium such as thermally conductive silicone grease. The heat dissipation fin 43 is located on the side away from the light emission port 11 of the reflecting member 21, and at least a portion of it is located within the heat dissipation passage 12.
[0139] As a result, after the heat conduction member 42 conducts heat from the cooling sheet 52 to the heat dissipation sheet 43, the fan 41 is driven to circulate air in the heat dissipation passage 12, quickly completing the air cooling of the heat dissipation sheet 43.
[0140] Furthermore, for example, if the heat dissipation assembly 400 is configured to dissipate heat from both the light source assembly 200 and the hot / cold damp cloth assembly 500 simultaneously, the heat dissipation passage 12 may include a first heat dissipation passage and a second heat dissipation passage.
[0141] Referring again to Figures 16 and 17, Figure 16 is an enlarged view of X in Figure 15, and Figure 17 is a cross-sectional view of the skin care device shown in Figure 14 along the BB direction. The first heat dissipation passage is connected between the air outlet of the housing 100, such as the first air outlet 13, and the fan 41, and at least one of the light source 22 and the reflective member 21 is located in the first heat dissipation passage, so that the fan 41 can dissipate heat from the light source 22 and / or the reflective member 21 in the first heat dissipation passage.
[0142] The second heat dissipation passage is connected between the air outlet of the housing 100, such as the second air outlet 14, and the fan 41. Heat dissipation fins 43 are provided inside the second heat dissipation passage, and the heat conductive member 42 conducts heat from the cooling sheet 52 to the heat dissipation fins 43, and the fan 41 air cools the second heat dissipation passage to achieve heat dissipation.
[0143] In some embodiments, the second heat dissipation passage and the first heat dissipation passage may be independent of each other, so that the inside of the skin care device can be partitioned and cooled, and good heat dissipation in the light source assembly 200 and the cold compress assembly 500 can be ensured.
[0144] Of course, the second heat dissipation passage and the first heat dissipation passage may partially intersect, and the embodiments of this application are not limited to this.
[0145] For example, the skin care device may further include a mounting bracket 700. The mounting bracket 700 is provided within the housing 100 and includes a first mounting chamber 71, a connecting passage 72, and a second mounting chamber 73.
[0146] The light source 22 and the reflective member 21 are placed in the first mounting chamber 71, one end of the connecting passage 72 communicates with the first mounting chamber 71, and the other end communicates with the outlet of the fan 41, so that the first mounting chamber 71 and the connecting passage 72 form at least a part of the first heat dissipation passage.
[0147] At least a portion of the heat dissipation fins 43 is located within the second mounting chamber 73, which communicates with the outlet of the fan 41 and forms at least a portion of the second heat dissipation passage.
[0148] The mounting bracket 700 may consist of at least two brackets. For example, the mounting bracket 700 may include a first bracket and a second bracket. The first bracket and the second bracket are assembled to form the first mounting chamber 71, the connecting passage 72, and the second mounting chamber 73 described above, thereby reducing the difficulty of manufacturing the mounting bracket 700.
[0149] The mounting bracket 700 may have corresponding grooves or ribs inside to facilitate the locking of the reflective member 21, optical filter 600, etc., but the embodiment of the present application is not limited to this.
[0150] The mounting bracket 700 may be further provided with corresponding openings for passing through the light guide member 51, the cooling sheet 52, etc., but this is not limited to the embodiments of the present application.
[0151] The fan 41 may be a centrifugal fan 41, an axial fan 41, or a through-flow fan 41, and is not limited to these in the embodiments of the present application.
[0152] For example, if the fan 41 is a centrifugal fan, the intake port of the volute of the centrifugal fan 41 is connected to an air outlet of the housing 100 such as the third air outlet 15, and the inlet of the connecting passage 72 and the inlet of the second mounting chamber 73 are arranged side by side with the outlet of the volute of the centrifugal fan 41. As a result, the centrifugal fan 41 drives outside air from the housing 100 into the volute of the centrifugal fan 41, and then the volute of the centrifugal fan 41 splits into two passages. One of the two passages discharges air through the connecting passage 72 and the first mounting chamber 71 to air cool the light source 22 and / or reflective member 21, and the other discharges air through the second mounting chamber 73 to air cool the heat dissipation fins 43 or the cold damp cloth assembly 500.
[0153] In some embodiments, the heat dissipation fins 43 may include a plurality of fins. The fins are provided projecting to one side in a second direction H2 relative to the second end and are located within the heat dissipation passage 12. The fan 41 is located on the side of the fins away from the reflector member 21 in a first direction H1, and the height of the fins in the second direction H2 is greater than or equal to the height of the light source assembly 200 in the second direction H2.
[0154] Compared to the configuration in which the fan 41 and fins are arranged side by side behind the light source assembly 200 in the second direction H2, in the embodiment of the present invention, by moving the fan 41 away from the light source assembly 200, the fins can be enlarged in the second direction H2, increasing the contact area between the heat dissipation fins 43 and the air, and significantly improving the heat dissipation effect of the heat dissipation fins 43.
