[0058] Please refer to Figures 1 to 3 , Figure 1 is a schematic diagram of the structure of a skin treatment device according to an embodiment of the present application, Figure 2 for Figure 1 A cross-sectional view of the skin treatment device along the AA direction, Figure 3 for Figure 2 The embodiment of the present application provides a skin treatment device, which is a hair removal device or a skin rejuvenation device, or any other skin treatment device, and the cold compress component 200 of the present application is not limited to this. The skin treatment device includes a housing 100, a cold compress component 200, a light output component 300 and a filter component 400.

[0059] The housing 100 is provided with a light emitting area 11. The cold compress component 200 is used for applying cold compress to the skin to be treated. The light emitting component 300 is installed in the housing 100, and is used to generate light emitted from the light emitting area 11 to the skin to be treated. The filter component 400 includes a first filter component 41 and a second filter component 42. The first filter component 41 and the second filter component 42 are sequentially arranged on the side of the light emitting component 300 facing the light emitting area 11, so that the light emitted from the light emitting component 300 to the light emitting area 11 can pass through the first filter component 41 and the second filter component 42 in sequence, and the first filter component 41 and the second filter component 42 are both used for filtering ultraviolet rays, so that the light generated by the light emitting component 300 can be filtered by the first filter component 41 and the second filter component 42 at least twice to reduce the ultraviolet rays emitted from the light emitting area 11.

[0060] The above is an overall description of the technical solution of the embodiment of the present application. The technical solution of the embodiment of the present application will be described below with reference to the filter component 400.

[0061] The wavelength threshold of the light filtered by the first filter component 41 is different from the wavelength threshold of the light filtered by the second filter component 42 .

[0062] Therefore, different types of first filter components 41 and second filter components 42 can be flexibly selected and combined according to different actual needs. For example, on the basis that both the first filter component 41 and the second filter component 42 can filter ultraviolet rays, at least one of the first filter component 41 and the second filter component 42 can also filter light of other wavelengths, thereby enriching the types of light that can be filtered by the filter assembly 400.

[0063] In some embodiments, the cold compress assembly 200 includes a light-transmitting component 21 disposed corresponding to the light-emitting area 11 , and the second light-filtering component 42 is located on a side of the first light-filtering component 41 close to the light-transmitting component 21 .

[0064] The first filter component 41 is used to filter light with a wavelength less than or equal to a first threshold, and the second filter component 42 is used to filter light with a wavelength less than or equal to a second threshold. The second threshold is less than the first threshold.

[0065] Therefore, when the light output component 300 is working, the first light filter component 41 filters or absorbs more light, while the second light filter component 42 filters or absorbs less light, so that the temperature of the second light filter component 42 is lower than that of the first light filter component 41. At this time, compared with the first light filter component 41 with a higher temperature, which is closer to the light-transmitting element 21, the heat transferred from the light filter component 400 to the cold compress component 200 in the embodiment of the present application can be reduced, so as to avoid the light filter component 400 affecting the cold compress effect of the cold compress component 200 on the treated skin.

[0066] In some embodiments, the first filter component 41 is used to filter light with a wavelength less than or equal to 560 nanometers. It is understandable that the wavelength of ultraviolet rays is 10 to 400 nanometers. Therefore, the first filter component 41 can pass most of the ultraviolet rays. In addition, the wavelength of light required by the skin treatment device for photorejuvenation and hair removal of the skin to be treated is usually between 460 nanometers and 1200 nanometers, and the wavelength of most of the light generated by the light output component 300 is below 1200 nanometers. Therefore, the first filter component 41 can effectively filter out the ultraviolet rays generated by the light output component 300 to damage the skin to be treated, and at the same time, the light emitted from the light output area 11 is more suitable for photorejuvenation and hair removal.

[0067] In some embodiments, the second filter component 42 is used to filter light with a wavelength less than or equal to 400 nanometers. It is understandable that in actual production, due to the limitations of the manufacturing process, it is difficult for the first filter component 41 to filter all the light with a wavelength less than or equal to 560 nanometers, so some ultraviolet rays will still pass through the first filter component 41. At this time, the second filter component 42 can effectively filter the ultraviolet rays passing through the first filter component 41, and finally reduce the ultraviolet rays emitted from the light exit area 11.

[0068] Of course, in some other implementations, the second threshold may also be greater than or equal to the first threshold, and this embodiment of the present application does not limit this.

[0069] The following will continue to illustrate the technical solution of the embodiment of the present application with reference to the structures of the first filter component 41 and the second filter component 42 .

[0070] Please continue to refer to Figure 4 , Figure 4 for Figure 3 A structural schematic diagram of the first filter component in FIG. The first filter component 41 includes a first substrate 411 and a first optical film layer 412 disposed on the first substrate 411. At least one of the first substrate 411 and the first optical film layer 412 is used to filter ultraviolet rays.

[0071] Therefore, according to different actual needs, the first substrate 411 can filter ultraviolet rays, while the first optical film layer 412 can be used to filter light of other wavelengths, focus light, even light, or have a decorative effect, etc. Optionally, the first optical film layer 412 can be used to filter ultraviolet rays, and the first substrate 411 can only be used to carry the first optical film layer 412, or the first substrate 411 can be used to filter light of other wavelengths, focus light, even light, or have a decorative effect, etc.

[0072] Of course, in some other embodiments, both the first substrate 411 and the first optical film layer 412 can be used to filter ultraviolet rays, so that at least two ultraviolet rays can be filtered at the first filter component 41, and then the second filter component 42 can achieve at least three filtering of ultraviolet rays, which can ultimately reduce the ultraviolet rays emitted from the light exit area 11.

[0073] In addition, the composite structure of the first substrate 411 and the first optical film layer 412 can also make the design and manufacture of the first filter component 41 more flexible. For example, in actual production, the first substrate 411 can be made of a material with high light transmittance, and then the first optical film layer 412 with ultraviolet filtering function is prepared on the first substrate 411 by printing, spraying, coating, etc., so that the first filter component 41 has the advantage of high light transmittance. Alternatively, the first substrate 411 can be made of a material with good heat insulation performance, and then the first optical film layer 412 with ultraviolet filtering function is prepared on the first substrate 411 by printing, spraying, coating, etc., so that the first filter component 41 has the advantage of good heat insulation performance, thereby reducing the heat generated by the light output component 300 from being transferred to the cold compress component 200, thereby improving the cold compress effect of the skin treatment device. Of course, according to actual industrial production needs, the first substrate 411 can also be made of a material with low cost, high hardness, etc., and the embodiment of the present application is not limited to this.

[0074] In some embodiments, the light-incoming surface and / or light-emitting surface of the first substrate 411 is provided with a first optical film layer 412. The light-incoming surface of the first substrate 411 is a surface of the first substrate 411 facing the light-emitting component 300, and the light-emitting surface of the first substrate 411 is a surface of the first substrate 411 facing the second light-filtering component 42.

[0075] That is to say, the first optical film layer 412 may be provided on only one of the light-entering surface and the light-emitting surface of the first substrate 411, or the first optical film layer 412 may be provided on all surfaces of the first substrate 411, so that both the light-entering surface and the light-emitting surface of the first substrate 411 are provided with the first optical film layer 412, thereby further improving the filtering ability of the first filter component 41 for ultraviolet rays, which is not limited in the embodiment of the present application.

[0076] Of course, in some implementations, the first filter component 41 may not be provided with the first optical film layer 412 , and this embodiment of the present application does not limit this.

[0077] In some embodiments, the first filter component 41 is a quartz filter for filtering ultraviolet rays. Then, when the first filter component 41 includes a first substrate 411 and a first optical film layer 412, the first substrate 411 can be made of a quartz material, and then the first optical film layer 412 is prepared on the light-incoming surface and / or light-outgoing surface of the first substrate 411. Alternatively, the first filter component 41 is directly made of a quartz material, so that the first filter component 41 does not have the first optical film layer 412, and the embodiment of the present application does not limit this.

[0078] Please continue to refer to Figure 5 , Figure 5 for Figure 3 In some embodiments, the second filter component 42 includes a second substrate 421 and a second optical film layer 422 disposed on the second substrate 421. At least one of the second substrate 421 and the second optical film layer 422 is used to filter ultraviolet rays.

[0079] Therefore, according to different actual needs, the second substrate 421 can filter ultraviolet rays, while the second optical film layer 422 can be used to filter light of other wavelengths, focus light, even light, or have a decorative effect, etc. Optionally, the second optical film layer 422 can be used to filter ultraviolet rays, and the second substrate 421 can only be used to carry the second optical film layer 422, or the second substrate 421 can be used to filter light of other wavelengths, focus light, even light, or have a decorative effect, etc.

[0080] Of course, in some other embodiments, the second substrate 421 and the second optical film layer 422 can both be used to filter ultraviolet rays, so that at least two ultraviolet rays are filtered at the second filter component 42, and at least three ultraviolet rays can be filtered in conjunction with the first filter component 41.

[0081] It is also necessary to explain that please continue to refer to Figure 6 , Figure 6 for Figure 3 When the first substrate 411, the first optical film layer 412, the second substrate 421, and the second optical film layer 422 are all used to filter ultraviolet rays, the filter assembly 400 can filter ultraviolet rays at least four times, and ultimately significantly reduce the ultraviolet rays emitted from the light exit area 11.

[0082] In addition, the composite structure of the second substrate 421 and the second optical film layer 422 can also make the design and manufacture of the second filter component 42 more flexible. For example, in actual production, the second substrate 421 can be made of a material with high light transmittance, and then the second optical film layer 422 with ultraviolet filtering function is prepared on the second substrate 421 by printing, spraying, coating, etc., so that the second filter component 42 has the advantage of high light transmittance. Alternatively, the second substrate 421 can be made of a material with good heat insulation performance, and then the second optical film layer 422 with ultraviolet filtering function is prepared on the second substrate 421 by printing, spraying, coating, etc., so that the second filter component 42 has the advantage of good heat insulation performance, thereby preventing the heat generated by the light output component 300 from being transferred to the cold compress component 200, thereby improving the cold compress effect of the skin treatment device. Of course, according to actual industrial production needs, the second substrate 421 can also be made of a material with low cost, high hardness, etc., and the embodiment of the present application is not limited to this.

[0083] In some embodiments, the light-incoming surface and / or light-emitting surface of the second substrate 421 is provided with a second optical film layer 422. The light-incoming surface of the second substrate 421 is the surface of the second substrate 421 facing the first filter component 41, and the light-emitting surface of the second substrate 421 is the surface of the second substrate 421 facing the light-emitting region 11.

[0084] That is to say, the second optical film layer 422 may be provided on only one of the light-incoming surface and the light-emitting surface of the second substrate 421, or the second optical film layer 422 may be provided on all surfaces of the second substrate 421, so that the second optical film layer 422 is provided on both the light-incoming surface and the light-emitting surface of the second substrate 421, and the embodiments of the present application are not limited to this.

[0085] Of course, the second filter component 42 may not be provided with the second optical film layer 422 , and this embodiment of the present application does not limit this.

[0086] In some embodiments, the second filter component 42 includes white glass for filtering ultraviolet rays. White glass is JGS-2 quartz material, which can filter light with a wavelength less than or equal to 180 nanometers, thereby filtering a portion of ultraviolet rays. Then, when the second filter component 42 includes a second substrate 421 and a second optical film layer 422, the second substrate 421 can be made of white glass material, and then the second optical film layer 422 is prepared on the light-incoming surface and / or light-outgoing surface of the second substrate 421. Alternatively, the second filter component 42 is directly made of white glass material, so that it does not have the second optical film layer 422, and the embodiment of the present application does not limit this.

[0087] In some embodiments, the first filter component 41 and the second filter component 42 can fit together. Thus, on the one hand, the structure inside the skin treatment device can be made more compact, so as to facilitate the miniaturization design of the skin treatment device; on the other hand, the technical problem that the temperature difference between the side of the first filter component 41 close to the light output component 300 and the side close to the cold compress component 200 is too large, which can easily cause water mist.

[0088] Optionally, the first filter component 41 and the second filter component 42 can be spaced apart. Then, on the one hand, since the first filter component 41 is located on the side of the second filter component 42 away from the cold compress component 200, the spacing between the first filter component 41 and the second filter component 42 can further increase the spacing between the first filter component 41 and the cold compress component 200, thereby reducing the heat indirectly transferred from the first filter component 41 to the cold compress component 200, thereby improving the cold compress effect of the cold compress component 200; on the other hand, it can also improve the technical problem that the temperature difference between the side of the first filter component 41 close to the light output component 300 and the side close to the cold compress component 200 is too large, which is easy to generate water mist.

[0089] When the first filter component 41 and the second filter component 42 are spaced apart, the filter assembly 400 further includes a sealing member 43. The sealing member 43 is at least partially disposed between the second filter component 42 and the light-transmitting member 21 to form a first sealed space 431 between the second filter component 42 and the light-transmitting member 21. The sealing member 43 is also at least partially disposed between the first filter component 41 and the second filter component 42 to form a second sealed space 432 between the first filter component 41 and the second filter component 42.

[0090] Furthermore, compared with direct contact between the second filter component 42 and the light-transmitting component 21, the air layer in the first sealed space 431 can reduce the heat exchange efficiency between the second filter component 42 and the light-transmitting component 21, thereby reducing the amount of heat transferred from the second filter component 42 to the light-transmitting component 21, so as to improve the cooling effect of the cold compress component 200; and the length of the heat exchange path between the light output component 300 and the light-transmitting component 21 can also be increased through the air layer in the first sealed space 431, so as to reduce the amount of heat transferred from the light output component 300 to the light-transmitting component 21, thereby improving the cooling effect of the cold compress component 200. In addition, the problem of excessive temperature difference on both sides of the second filter component 42 and easy water misting can be improved.

[0091] Similarly, compared with direct contact between the second filter component 42 and the first filter component 41, the air layer in the second sealed space 432 can reduce the heat exchange efficiency between the second filter component 42 and the first filter component 41, thereby reducing the heat transferred from the second filter component 42 to the light-transmitting component 21 to improve the cooling effect of the cold compress component 200; and the air layer in the second sealed space 432 can also increase the length of the heat exchange path between the light output component 300 and the light-transmitting component 21 to reduce the heat transferred from the light output component 300 to the light-transmitting component 21 to improve the cooling effect of the cold compress component 200. In addition, the problem of excessive temperature difference on both sides of the first filter component 41 and easy water mist can be improved.

[0092] For example, please continue to refer to Figure 7 and Figure 8 , Figure 7 for Figure 3 A second structural diagram of the seal of the filter assembly, Figure 8 for Figure 7 Exploded diagram of the embodiment of the present invention. The sealing member 43 may be a sealing ring, which is sandwiched between the light-transmitting member 21 and the first light-filtering member 41. The inner circumference of the sealing member 43 is provided with a mounting groove 433, and the circumferential edge of the second light-filtering member 42 is mounted in the mounting groove 433, so that the sealing member 43 is partially disposed between the first light-filtering member 41 and the light-transmitting member 21 to form a first sealed space 431 between the first light-filtering member 41 and the light-transmitting member 21, and the sealing member 43 is also partially disposed between the first light-filtering member 41 and the second light-filtering member 42 to form a second sealed space 432 between the first light-filtering member 41 and the second light-filtering member 42.

[0093] The above are some examples of the filter assembly 400 in the embodiment of the present application. The following will continue to illustrate with examples in combination with the structure of the cold compress assembly 200.

[0094] Please continue to refer to Fig. 9 , Fig. 9 for Figure 2Schematic diagram of the structure of the first air duct and the second air duct. It should be noted that the light exit area 11 can be an opening structure such as a light exit port or a light exit hole set on the shell. Optionally, the light exit area 11 can also be formed by some light-transmitting areas on the shell, which is not limited in the embodiment of the present application.

[0095] The cold compress assembly 200 is disposed at the light emitting area 11 . The cold compress assembly 200 may be installed in the light emitting area 11 , or the cold compress assembly 200 may be disposed on the peripheral side of the light emitting area 11 . This embodiment of the present application does not limit this.

[0096] For example, the cold compress assembly 200 may include the above-mentioned light-transmitting member 21 and the cooling sheet 22. The light-emitting area 11 is an opening structure such as a light outlet and a light outlet hole, and the light-transmitting member 21 is arranged in the light-emitting area 11 to transmit the light emitted by the light-emitting assembly 300. The cooling sheet 22 is thermally connected to the light-transmitting member 21. For example, the cooling sheet 22 is directly attached to the light-transmitting member 21 or attached to the light-transmitting member 21 through a heat-conducting medium such as thermal grease.

[0097] Furthermore, the light-transmitting member 21 can be cooled by the cooling sheet 22. The cooled light-transmitting member 21 is exposed from the light-emitting area 11 so as to come into contact with the skin. The light-transmitting member 21 can not only transmit the light of the light source to care for the user's skin, but also be cooled by the cooling sheet 22 to provide a cold compress for the user.

[0098] Specifically, the cooling plate 22 is also called a semiconductor cooling plate, which utilizes the Peltier effect of semiconductor materials. When direct current passes through a couple formed by two different semiconductor materials connected in series, heat can be absorbed and released at both ends of the couple, thereby achieving the purpose of cooling.

[0099] The light-transmitting member 21 may be made of sapphire or other light-guiding materials, which is not limited in the embodiment of the present application.

[0100] Optionally, the cold compress assembly 200 may further include a cold compress (not shown in the figure) and a cooling sheet 22. The light exit area 11 is an open structure such as a light exit port and a light exit hole, and the cold compress is arranged on the open end surface of the light exit area 11. The cooling sheet 22 is thermally connected to the cold compress; for example, the cooling sheet 22 is directly attached to the cold compress or attached to the cold compress through a heat conductive medium such as thermal grease.

[0101] Furthermore, the cold compress can be cooled by the cooling sheet 22, and the cooled cold compress is exposed from the light emitting area 11 so as to contact the skin to provide a cold compress for the user.

[0102] For example, the cold compress may be a ring-shaped metal part arranged around the light emitting area 11 .

[0103] The above are some examples of the cold compress assembly 200 of the embodiment of the present application. The following will continue to illustrate the technical solution of the embodiment of the present application with examples in combination with the heat dissipation structure of the embodiment of the present application.

[0104] The skin treatment device also includes a bracket assembly 500 and a heat dissipation assembly 600. The bracket assembly 500 is arranged in the housing 100, and the bracket assembly 500 or the bracket assembly 500 and the housing 100 form a first air duct 51 and a second air duct 52. The light output assembly 300 is arranged in the first air duct 51. The heat dissipation assembly 600 includes a temperature equalizer 61, a heat dissipation assembly 62 and a fan 63. The temperature equalizer 61 is thermally connected to the cold compress assembly 200. The heat dissipation assembly 62 is installed on the temperature equalizer 61 and is at least partially arranged in the second air duct 52. The air outlet of the fan 63 is respectively connected to the first air duct 51 and the second air duct 52, so that the fan 63 can drive air to flow through the first air duct 51 to dissipate heat to the light output assembly 300, and the fan 63 can drive air to flow through the second air duct 52 to dissipate heat to the cold compress assembly 200.

[0105] Furthermore, by driving the air flow through the first air duct 51 and the second air duct 52 by the fan 63, both the light emitting component 300 and the cold compress component 200 can be effectively cooled by air, so as to avoid the temperature at the light emitting component 300 being too high, which may cause abnormal operation or even damage of the skin treatment device, and to avoid the temperature of the cold compress component 200 being too high, which may affect the cold compress effect.

[0106] In addition, compared to directly manufacturing the shell 100 having the first air duct 51 and the second air duct 52, in the embodiment of the present application, the manufacturing difficulty of the first air duct 51 and the second air duct 52 can be reduced by forming the first air duct 51 and the second air duct 52 by cooperating with the shell 100 through the bracket assembly 500.

[0107] In some embodiments, the temperature-averaging member 61 is a temperature-averaging plate, and the first air duct 51 and the second air duct 52 are formed on different sides of the temperature-averaging member 61. One end of the temperature-averaging member 61 is thermally connected to the cold compress assembly 200. The other end of the temperature-averaging member 61 is located at the air outlet of the fan 63, so that the end of the temperature-averaging member 61 close to the fan 63 can divert the air flowing out of the fan 63 to the first air duct 51 and the second air duct 52.

[0108] Then, since the wind flowing out of the fan 63 flows through different sides of the temperature equalizing component 61, the contact area between the temperature equalizing component 61 and the cooling airflow is increased, thereby improving the heat dissipation efficiency of the temperature equalizing component 61, and then improving the heat dissipation effect of the cold compress component 200, and finally improving the overall heat dissipation effect of the skin treatment device.

[0109] It should be noted that one end of the temperature-equalizing element 61 is thermally connected to the cold compress assembly 200, and one end of the temperature-equalizing element 61 may be directly attached to the cold compress assembly 200 or attached to the cold compress assembly 200 through a heat-conducting medium such as thermal grease, so that the heat at the cold compress assembly 200 can be evenly transferred to various positions of the temperature-equalizing element 61, and then the contact area with the air is increased through the heat dissipation element 62 to improve the heat dissipation efficiency of the cold compress assembly 200. The heat dissipation element 62 may be a heat sink.

[0110] In some embodiments, the first air duct 51 is provided with a first anti-turbulence structure 511 . The first anti-turbulence structure 511 is used to limit turbulence formed in the first air duct 51 .

[0111] In some embodiments, the first anti-turbulence structure 511 includes a first guide plate, which is extended along the direction of the fan 63 toward the light output component 300, so that the wind passing through can be guided by the first guide plate to limit the formation of turbulence in the first air duct 51.

[0112] In some embodiments, the first anti-turbulence structure 511 may be disposed on an inner wall of the first air duct 51 that faces the temperature uniformity member 61 .

[0113] In some embodiments, a second anti-disturbance structure 521 is provided in the second air duct 52 , and the second anti-disturbance structure 521 is used to limit the formation of turbulence in the second air duct 52 .

[0114] Exemplarily, the housing 100 is provided with a housing air outlet 12 for the air in the first air duct 51 and the second air duct 52 to be discharged outside the housing 100. The housing air outlet 12 can be located on the side of the heat sink 62 away from the temperature equalizing member 61, so that a confluence space is formed between the housing air outlet 12 and the housing air outlet 12, so that the wind between adjacent heat sinks can first flow out to the confluence space and then be discharged from the housing air outlet 12.

[0115] Among them, the second anti-disturbance structure 521 includes a second guide plate arranged between the heat sink 62 and the shell air outlet 12, and the end of the second guide plate away from the heat sink 62 is inclined toward the shell air outlet 12 to limit the formation of turbulence between the heat sink 62 and the shell air outlet 12. The embodiment of the present application does not limit this.

[0116] Please continue to refer to Fig.10 , Fig.10 for Fig. 9 Schematic diagram of the structure of the second anti-spoiler structure provided in the heat sink. In some embodiments, the heat sink 62 includes a plurality of heat sinks disposed in the second air duct 52. The second anti-spoiler structure 521 may include a tooth portion, which is disposed on a side of the heat sink away from the temperature equalizer 61, that is, the tooth portion is located in the confluence space to limit the wind flowing out from between adjacent heat sinks to form a turbulent flow.

[0117] Please combine Fig. 9 and Fig.11 , Fig.11 for Figure 1 The cross-sectional view of the skin treatment device along the BB direction is shown. In some embodiments, the housing 100 is provided with a housing air outlet 12 and a housing air inlet 13, and the air inlet of the fan 63 is connected to the housing air inlet 13, so that the fan 63 can inhale air outside the housing 100 from the housing air inlet 13, and the air outlet of the fan 63 is respectively connected to the first air duct 51 and the second air duct 52, so that the fan 63 can blow air into the first air duct 51 and the second air duct 52, respectively, and the second air duct 52 is connected to the housing air outlet 12. The first air duct 51 is connected to one end of the second air duct 52 close to the housing air outlet 12, so that the first air duct 51 and the second air duct 52 form a Bernoulli structure at the connection point.

[0118] Therefore, the fan 63 can drive one path of wind to flow along the first air duct 51 to cool the light output component 300, and the fan 63 can drive another path of wind to flow along the second air duct 52 to dissipate heat from the cold compress component 200 through the temperature equalizer 61 and the heat sink 62. At this time, since the first air duct 51 and the second air duct 52 form a Bernoulli structure, when the fan 63 is running, the pressure at the outlet of the first air duct 51 and the second air duct 52 with a faster flow rate will be smaller, thereby bringing out or sucking out the wind in the second air duct to increase the flow rate in the second air duct, thereby improving the overall heat dissipation effect of the skin treatment device.

[0119] Exemplarily, the first air duct 51 may include a mounting section 512 and a connecting section 513. The mounting section 512 extends along the direction of the fan 63 toward the light exit area 11, and one end of the mounting section 512 close to the fan 63 is connected to the fan 63 to form an air inlet of the first air duct 51. The light exit assembly 300 is at least partially disposed in the mounting section 512. The connecting section 513 is connected to the mounting section 512, and extends from the mounting section 512 toward the housing air outlet 12 to be connected to one end of the second air duct 52 close to the housing air outlet 12.

[0120] In some embodiments, the connecting section 513 may be located at one end of the light output assembly 300 in the length direction.

[0121] Optionally, there may be two connecting sections 513 , and a connecting section 513 may be provided at each end of the light output component 300 in the length direction.

[0122] The above are some examples of the heat dissipation structure in the embodiment of the present application. The following will continue to illustrate the technical solution of the embodiment of the present application with examples in combination with the structure of the light output component 300.

[0123] According to the different types of light generated by the light emitting component 300, the skin treatment device can be divided into different types. For example, the light emitting component 300 can be used to generate laser, which is a laser light source component, and the skin treatment device is a laser skin treatment device; for example, the light emitting component 300 can be used to generate IPL light (intense pulsed light), which is an IPL light source component (such as a xenon lamp component), and the skin treatment device is an intense pulsed light skin treatment device; for example, the light emitting component 300 can be an LED light source component.

[0124] In the present application, the light emitting component 300 is mainly used as an IPL light source component as an example for explanation. The light emitting principle of this type of skin treatment equipment is: the capacitor is connected to the power supply, and the transformer component boosts the voltage to charge the capacitor. When the capacitor is charged to a preset value and the controller receives a trigger signal, the electric energy in the capacitor is released, and the instantaneous voltage can reach several hundred volts, thereby stimulating the lamp to instantly release strong pulsed light, thereby completing a light emission.

[0125] Please continue to refer to Fig.12 , Fig.12 for Figure 1 The structure diagram of the light emitting assembly and the circuit board assembly of the skin treatment device shown in the figure. The light emitting assembly 300 may include a reflective cup 31 and a lamp tube 32. The reflective cup 31 is provided with an arc groove. The lamp tube 32 is at least partially arranged in the arc groove. Furthermore, the notch of the arc groove can face the light emitting area 11, so that the light generated by the lamp tube 32 is reflected and converged to the light emitting area 11 through the reflective cup 31, thereby increasing the light output of the skin treatment device.

[0126] It can also be understood that the number of the lamp tubes 32 can be one, or can be at least two, such as two, three, four or five, which is not limited in the embodiment of the present application.

[0127] When the number of the lamp tubes 32 is at least two, such as the lamp tubes 32 , at least two lamp tubes 32 are disposed at intervals.

[0128] Furthermore, the skin care effect of the skin care device can be improved by emitting light from multiple lamps 32. For example, multiple lamps 32 can be switched on and off synchronously, so that the lamp 32 assembly can perform skin care at a higher maximum power, thereby improving the skin care effect of the skin care device; or different lamps 32 can emit light individually or in combination, so that the lamp 32 assembly can have at least three light emission modes, so as to adjust to a more suitable light emission mode according to the actual needs of the user, thereby improving the skin care effect of the skin care device.

[0129] When there are at least two lamp tubes 32, at least two lamp tubes 32 are disposed in the same arc groove, so that the light output of the two lamp tubes 32 is more uniform.

[0130] In some embodiments, the skin treatment device may further include a circuit board assembly 700. The circuit board assembly 700 includes a circuit board 71 and a conductive bracket 72. The circuit board 71 is disposed in the housing 100, and the conductive bracket 72 is disposed on the circuit board 71. The end of the lamp tube 32 is mounted on the conductive bracket 72 to support the circuit board 71 and be electrically connected to the circuit board 71.

[0131] In some embodiments, the reflective cup 31 is electrically connected to the circuit board 71 , and the distance between the reflective component and the lamp 32 is smaller than a preset distance, so that the reflective component can excite the lamp 32 .

[0132] For example, the lamp tube 32 can be a xenon lamp tube, and the two ends or poles of the xenon lamp tube are electrically connected to the circuit board 71 through the conductive bracket 72. At this time, the circuit board 71 can excite or trigger the lamp tube 32 through the reflective cup 31, thereby reducing the components of the skin treatment device through the reuse of the reflective cup 31, so as to make the skin treatment device more compact.

[0133] In some embodiments, the preset distance may be less than or equal to 2 mm. For example, the distance between the reflective cup 31 and the lamp tube 32 is 2 mm, 1.4 mm, 0.5 mm, or 0 mm. Of course, when the distance between the reflective cup 31 and the lamp tube 32 is 0 mm, it can also be understood that the reflective cup 31 and the lamp tube 32 are directly abutted.

[0134] Optionally, in some implementations, a wire (such as a filament) may be wound around the surface of the lamp tube 32 , and the wire may be electrically connected to the circuit board 71 for exciting the lamp tube 32 , which is not limited in the embodiment of the present application.

[0135] In some embodiments, when the number of lamp tubes 32 is at least two, the ends of at least two lamp tubes 32 on the same side are installed on the same conductive bracket 72. Compared with the case where the ends of each lamp tube 32 are installed through different conductive brackets 72, on the one hand, the number of conductive brackets 72 can be reduced, and on the other hand, the current size of each lamp tube 32 can be made closer, so that the luminous brightness of multiple lamp tubes 32 can be closer, thereby improving the uniformity of light output from the light output component 300.

[0136] In some embodiments, the ends of all the lamp tubes 32 on the same side may be mounted on the circuit board 71 through the same conductive bracket 72 .

The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
