[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0062] This application provides a skin care device, which can be a light-based skin care device for providing light-based treatments. For example, the skin care device may include a hair removal device and a skin rejuvenation device.

[0063] It should be noted that skin care devices may only have the function of light therapy, or they may also have functions such as electrical stimulation therapy. This application does not limit this.

[0064] Phototherapy can involve irradiating the skin to be treated with IPL light sources, laser light sources, or LED light sources to care for the skin.

[0065] Electrical stimulation care can be performed by applying electrical stimulation currents such as radiofrequency current, intermediate frequency current, and microcurrents (such as EMS current) to the skin to be treated.

[0066] Below, we will first introduce the technical solution of the embodiments of this application in conjunction with light therapy.

[0067] Please refer to Figure 1 and Figure 2 The skin care device may include a housing 100 and a light-emitting assembly 200. The housing 100 is provided with a light-emitting hole 121, and the light-emitting assembly 200 is used to generate light that is emitted from the light-emitting hole 121 onto the skin to be treated.

[0068] Furthermore, during use, the light-emitting hole 121 can be directed toward the skin to be treated, so that the light-emitting component 200 can provide light therapy to the skin to be treated.

[0069] In some embodiments, the housing 100 may be elongated, so that the housing 100 has a length direction.

[0070] Therefore, one end of the housing 100 along its length can form a nursing end 11. The light emission hole 121 can be located on the outer periphery of the nursing end 11, or it can be located on the end face of the nursing end 11.

[0071] For example, the outer periphery of the nursing end 11 is provided with an outward protrusion 12, and the light outlet 121 is disposed through the end face of the outward protrusion 12.

[0072] In some embodiments, the cross-sectional area of ​​the protrusion 12 is reduced along the direction close to the light emission hole 121. This allows the end face where the light emission hole 121 is located to be smaller, so that the user can accurately fit the light emission hole 121 onto the user's skin to be treated.

[0073] Please continue to refer to this. Figure 3 and Figure 4 In some embodiments, the light-emitting assembly 200 includes at least two light sources 21.

[0074] Furthermore, the skincare effect of the device can be improved by using two light sources 21. For example, at least two light sources 21 can be switched synchronously, allowing the light-emitting component 200 to apply skincare products at a higher maximum power, thereby improving the skincare effect of the device. Alternatively, different light sources 21 can emit light individually or in combination, allowing the light-emitting component 200 to have at least three light emission modes, which can be adjusted to a more suitable light emission mode according to the user's actual needs, thereby improving the skincare effect of the device.

[0075] For example, the light-emitting assembly 200 includes a first light source 211 and a second light source 212, both of which are used to generate light that is directed from the light-emitting hole 121 toward the skin to be treated.

[0076] It should be noted that when there are two light sources 21, one of them is the first light source 211 and the other is the second light source 212. When there are at least three light sources 21, the first light source 211 and the second light source 212 can be any two of the multiple light sources 21, and this embodiment does not limit this.

[0077] The light source 21 may include a lamp tube. For example, the first light source 211 includes a first lamp tube, and the second light source 212 includes a second lamp tube. This application embodiment does not limit this.

[0078] In some embodiments, the light-emitting assembly 200 may further include a reflector 22. The reflector 22 is used to reflect a portion of the light generated by the light source 21 toward the light-emitting aperture 121.

[0079] For example, the first light source 211 is at least partially disposed within the reflector cup 22, such that the reflector cup 22 is used to reflect a portion of the light generated by the first light source 211 to the light outlet 121.

[0080] For example, the reflector cup 22 includes a first arcuate portion 221, which is arranged around the first lamp tube.

[0081] For example, the second light source 212 is at least partially disposed within the reflector cup 22, such that the reflector cup 22 is used to reflect a portion of the light generated by the second light source 212 to the light outlet 121.

[0082] For example, the reflector cup 22 includes a second arcuate portion 222, which is arranged around the second lamp tube.

[0083] In some embodiments, the reflector cup 22 further includes a first deflection portion 223, one end of which is away from the light-emitting hole 121 and connected to the end of the first arc-shaped portion 221 away from the second arc-shaped portion 222. The end of the first deflection portion 223 near the light-emitting hole 121 is deflected toward the side near the second arc-shaped portion 222.

[0084] Furthermore, the light emitted by the first light source 211 or the second light source 212 towards the first deflection portion 223 can be reflected and focused towards the light outlet 121 to increase the brightness of the light at the light outlet 121.

[0085] In some embodiments, the reflector cup 22 further includes a second deflection segment 224, one end of which is away from the light-emitting hole 121 and connected to the end of the second arcuate portion 222 away from the first arcuate portion 221, and the end of the second deflection segment 224 near the light-emitting hole 121 is deflected toward the side near the first arcuate portion 221.

[0086] Furthermore, the light rays emitted by the first light source 211 or the second light source 212 toward the second deflection section 224 can be reflected and converged toward the light outlet 121 to increase the brightness of the light at the light outlet 121.

[0087] In some implementations, the skin care device may also include a cold compress function.

[0088] For example, such as Figure 2 As shown, the skin care device also includes a cold compress component 300, which is at least partially disposed at the light outlet 121 for applying a cold compress to the skin to be treated.

[0089] It should be noted that the cooling compress component 300 is at least partially disposed at the light emission hole 121. The cooling compress component 300 may be disposed around the opening of the light emission hole 121, or the cooling compress component 300 may be partially disposed through the light emission hole 121. This application embodiment does not limit this.

[0090] For example, the cooling compress assembly 300 may include a light-transmitting element 31 passing through the light-emitting hole 121. Furthermore, on the one hand, the light-transmitting element 31 can directly contact the skin to be treated for cooling; on the other hand, the light generated by the light-emitting assembly 200 can pass through the light-transmitting element 31 for phototherapy of the skin to be treated.

[0091] The cooling assembly 300 may further include a cooling pad 32, which is thermally connected to the light-transmitting element 31 for cooling the light-transmitting element 31. The cooling pad 32 may be a semiconductor cooling pad.

[0092] In some embodiments, the skin care device further includes a light filter assembly 400. The light filter assembly 400 is used to filter the light emitted from the light emitting assembly 200 toward the light emitting aperture 121. Therefore, the light required for phototherapy can pass through the light filter assembly 400 and be directed toward the skin to be treated.

[0093] For example, the filter component 400 can be used to transmit light with wavelengths between 420 nanometers and 1200 nanometers. In practical use, the light wavelength required for hair removal can be between 420 nanometers and 1200 nanometers, while the light wavelength required for skin rejuvenation can be between 600 nanometers and 1200 nanometers. This allows the skin care device to simultaneously perform skin rejuvenation and hair removal functions.

[0094] Please continue to refer to this. Figure 5 In some embodiments, the light filtering assembly 400 includes a first filter 41 disposed between the first light source 211 and the light emission aperture 121 for filtering the light emitted from the first light source 211 toward the light emission aperture 121.

[0095] Through the inventor's creative work, it was discovered that in related technologies, the first filter 41 can be an absorptive filter, that is, the first filter 41 is used to absorb light of a first preset wavelength to filter the light emitted from the first light source 211 towards the light exit aperture 121. However, after the first filter 41 absorbs light of the first preset wavelength, its temperature will rise, which will cause the temperature at the light exit aperture 121 to rise accordingly, ultimately affecting the user's experience.

[0096] Based on this, in some embodiments, the first filter 41 includes a first reflective surface 411 facing the first light source 211. The first reflective surface 411 is used to reflect light of a first preset wavelength to filter the light emitted by the first light source 211 toward the light outlet 121.

[0097] Furthermore, since the first reflective surface 411 can block the light of the first preset wavelength from passing through the first filter 41 on the side facing the first light source 211, so as to prevent the light of the first preset wavelength from entering the first filter 41 and causing the temperature of the first filter 41 to be too high, the temperature at the light outlet 121 can also be reduced accordingly, thereby reducing the heat sensation on the skin to be treated.

[0098] It is also understandable that when a cooling component 300 is provided at the light outlet 121, the high temperature of the first filter 41 can be avoided from affecting the cooling effect of the cooling component 300.

[0099] In some embodiments, the light filtering assembly 400 includes a second filter 42 disposed between the second light source 212 and the light emission aperture 121 for filtering the light emitted from the second light source 212 toward the light emission aperture 121.

[0100] Similarly, through the inventors' creative work, it was discovered that in related technologies, the second filter 42 can be an absorptive filter, that is, the second filter 42 is used to absorb light of a second preset wavelength to filter the light emitted from the second light source 212 towards the light exit aperture 121. However, after the second filter 42 absorbs light of the second preset wavelength, its temperature will increase, which will cause the temperature at the light exit aperture 121 to also increase accordingly, ultimately affecting the user's experience.

[0101] Based on this, in some embodiments, the second filter 42 includes a second reflective surface 421 facing the second light source 212. The second reflective surface 421 is used to reflect light of a second preset wavelength to filter the light emitted by the second light source 212 toward the light outlet 121.

[0102] Furthermore, since the second reflective surface 421 can block the light of the second preset wavelength from passing through the second filter 42 on the side facing the second light source 212, so as to prevent the light of the second preset wavelength from entering the second filter 42 and causing the temperature of the second filter 42 to be too high, the temperature at the light outlet 121 can also be reduced accordingly, thereby reducing the heat sensation on the skin to be treated.

[0103] It is also understandable that when a cooling component 300 is provided at the light outlet 121, the high temperature of the second filter 42 can be avoided from affecting the cooling effect of the cooling component 300.

[0104] It should be noted that, in the embodiments of this application, the first filter 41 may be provided with a first reflective surface 411 and the second filter 42 may be an absorptive filter; the first filter 41 may be an absorptive filter and the second filter 42 may be provided with a second reflective surface 421; or the first filter 41 may be provided with a first reflective surface 411 and the second filter 42 may be provided with a second reflective surface 421. The embodiments of this application do not limit this.

[0105] It should also be noted that the first preset wavelength and the second preset wavelength can be the same or different, and this application does not limit this.

[0106] In some embodiments, the first filter 41 and the second filter 42 may be arranged side by side between the light-emitting aperture 121 and the light-emitting assembly 200.

[0107] The end of the first filter 41 near the second filter 42 and the end of the second filter 42 near the first filter 41 are both inclined away from the light-emitting aperture 121, so that the first filter 41 and the second filter 42 are arranged in a V-shape.

[0108] Therefore, the light generated by the first light source 211 and the second light source 212 can be focused at the light outlet 121 to increase the light intensity at the light outlet 121, thereby improving the skin care effect of the skin care device.

[0109] In some embodiments, the filter assembly 400 further includes a filter holder 43 disposed within the housing 100, wherein the first filter 41 and the second filter 42 are both disposed within the filter holder 43.

[0110] Furthermore, the first filter 41 and the second filter 42 can be installed simultaneously through the filter holder 43, making the assembly of the skin care device simpler.

[0111] For example, please refer to the following: Figure 4 and Figure 5 The filter assembly 400 includes a first mounting portion 431 and a second mounting portion 432. A first filter 41 is disposed on the first mounting portion 431, and a second filter 42 is disposed on the second mounting portion 432.

[0112] Therefore, the first mounting portion 431 and the second mounting portion 432 can be bent and connected, with the side of the first mounting portion 431 away from the second mounting portion 432 and the side of the second mounting portion 432 away from the first mounting portion 431 both inclined towards the light outlet 121. Furthermore, the first mounting portion 431 and the second mounting portion 432 can have a V-shaped structure; correspondingly, the first filter 41 and the second filter 42 are also arranged in a V-shape.

[0113] In some embodiments, the first filter 41 is mounted between the reflector cup 22 and the filter holder 43.

[0114] For example, the filter holder 43 is provided with a first mounting through hole 433, and the inner wall of the first mounting through hole 433 is provided with a first stepped surface 434 facing the first light source 211. The first filter 41 is snapped between the first stepped surface 434 and the light emitting component 200.

[0115] Therefore, in the actual assembly process, the first filter 41 is placed into the first mounting through hole 433, and then the filter bracket 43 and the light-emitting component 200 are installed in place. The filter bracket 43 and the light-emitting component 200 can cooperate to limit the first filter 41.

[0116] On the one hand, compared to the filter holder 43 forming an annular groove to clamp and fix the first filter 41, the first mounting through hole 433 with a stepped hole structure can make the manufacturing of the filter holder 43 simpler; on the other hand, compared to setting an additional clamping member to clamp and fix the first filter 41 to the first stepped surface 434, and reusing the light emitting component 200 to clamp the first filter 41, the embodiments of this application can reduce the number of parts required for the skin care device, so as to reduce the cost and assembly difficulty of the skin care device.

[0117] The first mounting through hole 433 can be provided in the first mounting part 431.

[0118] In some embodiments, the second filter 42 is mounted between the reflector cup 22 and the filter holder 43.

[0119] For example, the filter holder 43 is provided with a second mounting through hole 435, and the inner wall of the second mounting through hole 435 is provided with a second stepped surface 436 facing the second light source 212. The second filter 42 is snapped between the second stepped surface 436 and the light emitting assembly 200.

[0120] Therefore, in the actual assembly process, the second filter 42 is placed into the second mounting through hole 435, and then the filter bracket 43 and the light-emitting assembly 200 are installed in place. The filter bracket 43 and the light-emitting assembly 200 can then cooperate to limit the position of the second filter 42.

[0121] On the one hand, compared to the filter holder 43 forming an annular groove to clamp and fix the second filter 42, the second mounting through hole 435 with a stepped hole structure can make the manufacturing of the filter holder 43 simpler; on the other hand, compared to setting an additional clamping member to clamp and fix the second filter 42 to the second stepped surface 436, and reusing the light emitting component 200 to clamp the second filter 42, the embodiments of this application can reduce the parts required for the skin care device, so as to reduce the cost and assembly difficulty of the skin care device.

[0122] The second mounting through hole 435 can be provided in the second mounting part 432.

[0123] In some embodiments, the housing 100 is further provided with a heat dissipation duct 51, which can be used to dissipate heat from the light-emitting component 200.

[0124] For example, the light-emitting component 200 is at least partially disposed within the heat dissipation duct 51, thereby allowing the light-emitting component 200 to be cooled by the air flowing in the heat dissipation duct 51.

[0125] In some embodiments, the filter holder 43 is at least partially disposed within the heat dissipation duct 51. Both sides of the filter holder 43 abut against the inner wall of the heat dissipation duct 51, and the middle part of the filter holder 43 is recessed towards the light-emitting component 200 and abuts against the reflector cup 22, so that the filter holder 43 is engaged between the inner wall of the heat dissipation duct 51 and the reflector cup 22.

[0126] Furthermore, in the direction perpendicular to the end face of the light-emitting hole 121, the filter holder 43 can be limited by the reflector cup 22 to prevent the filter holder 43 from falling off or shifting; in the direction parallel to the end face of the light-emitting hole 121, the two sides of the filter holder 43 can be clamped by the inner wall of the heat dissipation duct 51, thereby fixing the filter holder 43.

[0127] For example, the side of the first mounting part 431 facing away from the second mounting part 432 and the side of the second mounting part 432 facing away from the first mounting part 431 both abut against the inner wall of the heat dissipation duct 51, and the connection between the first mounting part 431 and the second mounting part 432 is recessed toward the light-emitting component 200 to abut against the reflector cup 22.

[0128] Therefore, it can prevent the first mounting part 431 and the second mounting part 432 from falling off from the inner wall of the heat dissipation duct 51 after the included angle between them becomes smaller.

[0129] In some embodiments, the reflector cup 22 further includes an abutment portion 225, which is located between the first lamp tube and the second lamp tube. The abutment portion 225 is bent and connected to the first arc-shaped portion 221 and the second arc-shaped portion 222 respectively. The abutment portion 225 abuts against the side of the filter assembly 400 away from the light outlet hole 121, so that the filter assembly 400 is snapped and fixed between the abutment portion 225 and the inner wall of the second heat dissipation duct 512.

[0130] That is to say, the connection between the first mounting part 431 and the second mounting part 432 can abut against the abutment part 225 of the reflector cup 22 to achieve the snap-fit ​​fixation of the filter assembly 400.

[0131] In some embodiments, the filter holder 43 is at least partially disposed within the heat dissipation duct 51. The inner wall of the heat dissipation duct 51 is provided with a slot 513, and the filter holder 43 is engaged with the slot 513, thereby making the installation of the filter holder 43 more stable and reliable through the structure of the slot 513.

[0132] In some embodiments, the heat dissipation duct 51 can also be used to dissipate heat from the cooling assembly 300. For example, the heat dissipation duct 51 includes a first heat dissipation duct 511 and a second heat dissipation duct 512, whereby the first heat dissipation duct 511 is used to dissipate heat from the cooling assembly 300 and the second heat dissipation duct 512 is used to dissipate heat from the light-emitting assembly 200.

[0133] Furthermore, by dissipating heat through the first heat dissipation duct 511 and the second heat dissipation duct 512 respectively, the cooling component 300 and the light-emitting component 200 can be effectively cooled.

[0134] It should be noted that the first heat dissipation duct 511 can be used only for heat dissipation of the cooling component 300, and the first heat dissipation duct 511 can also be used simultaneously for heat dissipation of the light-emitting component 200. This application embodiment does not limit this.

[0135] The second heat dissipation duct 512 can be used solely for heat dissipation of the light-emitting component 200, or it can also be used simultaneously for heat dissipation of the cooling component 300. This application embodiment does not limit this.

[0136] In some embodiments, the reflector cup 22 is at least partially disposed within the second heat dissipation duct 512, so that the second heat dissipation duct 512 is used to dissipate heat from the light-emitting component 200. A flow space 514 is provided between the outer wall of the reflector cup 22 and the inner wall of the second heat dissipation duct 512, so that air flowing through the second heat dissipation duct 512 can flow through the flow space 514.

[0137] Furthermore, compared to the outer wall of the reflector cup 22 being tightly fitted to the inner wall of the second heat dissipation duct 512, the flow space 514 can increase the contact area between the reflector cup 22 and the air flowing through the second heat dissipation duct 512, thereby improving the heat dissipation effect of the reflector cup 22.

[0138] For example, the circulation space 514 includes a first circulation space 5141, which is located on the side of the first arcuate portion 221 that is away from the second arcuate portion 222. This allows for better heat dissipation on the side of the first arcuate portion 221 that is away from the second arcuate portion 222.

[0139] For example, the circulation space 514 includes a second circulation space 5142, which is located on the side of the second arcuate portion 222 that is away from the first arcuate portion 221. This allows for better heat dissipation on the side of the second arcuate portion 222 that is away from the first arcuate portion 221.

[0140] For example, the circulation space 514 includes a third circulation space 5143, which is located between the first arcuate portion 221 and the second arcuate portion 222. This allows for better heat dissipation in the area where the first arcuate portion 221 and the second arcuate portion 222 are close to each other.

[0141] It is understood that the circulation space 514 may include only one of the first circulation space 5141, the second circulation space 5142 and the third circulation space 5143, or it may include at least two of them. This application embodiment does not limit this.

[0142] When the circulation space 514 includes the first circulation space 5141, the second circulation space 5142, and the third circulation space 5143, it can ensure that each area of ​​the reflector cup 22 receives good heat dissipation.

[0143] In some embodiments, the light-transmitting element 31 of the cooling assembly 300 can pass through the light-emitting hole 121, and the second heat dissipation duct 512 is at least partially formed between the filter assembly 400 and the light-transmitting element 31. Furthermore, the air flowing through the second heat dissipation duct 512 can be reused to dissipate heat from the light-transmitting element 31, thereby improving the cooling effect of the light-transmitting element 31.

[0144] For example, the first filter 41 and the second filter 42 are arranged side by side between the light-emitting component 200 and the light-transmitting element 31, and the end of the first filter 41 near the second filter 42 and the end of the second filter 42 near the first filter 41 are both inclined away from the light-transmitting element 31. The second heat dissipation duct 512 is at least partially located between the first filter 41, the second filter 42 and the light-transmitting element 31.

[0145] Therefore, by arranging the first filter 41 and the second filter 42 in a V-shape, the space on the side of the first filter 41 and the second filter 42 facing the light-transmitting element 31 can be fully used for heat dissipation to improve the heat dissipation effect.

[0146] The technical solutions of the embodiments of this application will be further described below in conjunction with the heat dissipation of the cooling component 300.

[0147] like Figure 2 As shown, in some embodiments, the skin care device further includes a heat dissipation assembly 600 disposed within the housing 100. The heat dissipation assembly 600 includes a heat spreader 61 and a heat sink assembly 62.

[0148] The heat spreader 61 and the cooling assembly 300 are thermally connected; for example, the heat spreader 61 and the cooling element 32 of the cooling assembly 300 are thermally connected. The heat sink assembly 62 is disposed on the heat spreader 61, and the heat sink assembly 62 is at least partially disposed in the first heat dissipation duct 511 so that the first heat dissipation duct 511 is used to dissipate heat from the cooling assembly 300.

[0149] Please combine Figure 2 and Figure 6 In some embodiments, the heat sink assembly 62 includes a first heat sink assembly 621 and a second heat sink assembly 622. The first heat sink assembly 621 is disposed on the side of the heat spreader 61 facing the first heat dissipation duct 511, such that the first heat sink assembly 621 is at least partially located within the first heat dissipation duct 511. The second heat sink assembly 622 is disposed on the side of the heat spreader 61 away from the first heat sink assembly 621.

[0150] Furthermore, the contact area between the heat dissipation component 600 and the air can be increased by the first heat sink assembly 621 and the second heat sink assembly 622, thereby improving the heat dissipation effect of the heat dissipation component 600 on the cooling component 300.

[0151] In some embodiments, the first heat dissipation duct 511 is located on the side of the second heat dissipation duct 512 away from the light outlet 121. The first heat dissipation duct 511, the second heat dissipation duct 512 and the cooling assembly 300 are all located on the same side of the heat spreader 61. The portion of the heat spreader 61 corresponding to the first heat dissipation duct 511 is provided with a heat sink assembly 62, and the portion of the heat spreader 61 corresponding to the second heat dissipation duct 512 is also provided with a heat sink assembly 62.

[0152] Furthermore, compared to providing the heat sink assembly 62 only at the first heat dissipation duct 511, this embodiment of the application also provides the heat sink assembly 62 at the second heat dissipation duct 512, which makes the area of ​​the heat sink assembly 62 larger, thereby improving the heat dissipation effect of the heat dissipation assembly 600.

[0153] Please continue to refer to this. Figure 7 and Figure 8 In some embodiments, the heat dissipation assembly 600 may further include a fan 63. The fan 63 is used to drive air to flow through the first heat dissipation duct 511 for heat dissipation of the cooling assembly 300, and the fan 63 is also used to drive air to flow through the second heat dissipation duct 512 for heat dissipation of the light-emitting assembly 200.

[0154] In some embodiments, the first heat dissipation duct 511 and the second heat dissipation duct 512 are both extended along the length direction of the housing 100, and the ends of the first heat dissipation duct 511 and the second heat dissipation duct 512 on the same side along the length direction are connected to the fan 63.

[0155] Furthermore, compared to the tortuous arrangement of the first heat dissipation duct 511 and the second heat dissipation duct 512, the fan 63 of this embodiment can drive air to flow more smoothly along the length of the housing 100 through the first heat dissipation duct 511 and the second heat dissipation duct 512, thereby improving the heat dissipation effect of the light-emitting component 200 and the cooling component 300.

[0156] In some embodiments, the skin care device further includes an air duct support 500 disposed within the housing 100, the air duct support 500 defining at least a portion of the inner wall of the first heat dissipation air duct 511 and at least a portion of the inner wall of the second heat dissipation air duct 512.

[0157] Furthermore, compared to forming the first heat dissipation duct 511 and the second heat dissipation duct 512 on the inner wall of the housing 100, the embodiments of this application define the first heat dissipation duct 511 and the second heat dissipation duct 512 by an additional duct support 500, which can reduce the forming difficulty of the first heat dissipation duct 511 and the second heat dissipation duct 512.
