[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0037] In addition, the "plurality" in the embodiments of the present invention refers to two or more than two. In view of this, in the embodiments of the present invention, "plurality" can also be understood as "at least two". "At least one" can be understood as one or more, for example, one, two or more. For example, including at least one means including one, two or more, and there is no limit on which ones are included. For example, including at least one of A, B and C, then A, B, C, A and B, A and C, B and C, or A, B and C can be included.

[0038] The embodiment of the utility model provides a skin treatment device, which may be a hair removal device or a skin rejuvenation device, etc. Of course, the skin treatment device may also be any other device for treating the skin, which is not limited by the embodiment of the utility model.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the skin treatment device provided by the embodiment of the utility model. Figure 2 for Figure 1 A cross-sectional view of the skin treatment device along the AA direction Figure 1 The skin treatment device may include a housing 100 and a light emitting component 200. The housing 100 may be provided with a light emitting area 11. The light emitting component 200 is disposed in the housing 100 to generate light emitted from the light emitting area 11 toward the skin.

[0040] The light exit area 11 may be an opening structure provided on the housing 100 .

[0041] Optionally, the light emitting area 11 may also be formed by some light-transmitting areas on the housing 100. For example, at least part of the housing 100 of the skin treatment device, such as the head housing, may be made of a light-transmitting material, and a light-shielding layer is provided in a local area of ​​the head housing to form the light emitting area 11 where the light-shielding layer is not provided on the head housing, and the embodiment of the utility model is not limited to this.

[0042] It can also be understood that, according to the different types of light generated by the light output component 200, the skin treatment device can be divided into different types. For example, the light output component 200 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 output component 200 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 output component 200 can be an LED light source component.

[0043] The present invention is mainly explained below by taking the light emitting component 200 as an IPL light source component as an example. The light emitting principle of this type of skin treatment equipment is: a capacitor is connected to a power supply, and a voltage transformer is used to step up 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 tube 21 to instantly release strong pulsed light, thereby completing one light emission.

[0044] Please continue to refer to Figure 2 and Figure 3 , Figure 3 for Figure 2 The light emitting assembly 200 of the skin treatment device is shown as a schematic diagram of the structure of the first light emitting assembly. The light emitting assembly 200 may include a lamp tube 21 and a reflective component 22. The reflective component 22 is used to reflect at least part of the light generated by the lamp tube 21 to the light emitting area 11 toward the skin to be treated, so as to increase the intensity or energy of the light emitted from the light emitting area 11 toward the skin to be treated.

[0045] For example, the reflective member 22 may include a surrounding portion 221. The surrounding portion 221 is disposed around the lamp tube 21, and the surrounding portion 221 includes a first side edge 2211 and a second side edge 2212 disposed at intervals along the circumference of the lamp tube 21. A light outlet 2213 facing the light outlet area 11 is formed between the first side edge 2211 and the second side edge 2212, so as to reflect at least part of the light generated by the lamp tube 21 to be emitted from the light outlet area 11 toward the skin to be treated.

[0046] Please continue to combine Figure 3 and Figure 4 , Figure 4 for Figure 1The cross-sectional view of the skin treatment device along the BB direction is shown. In some embodiments, the skin treatment device may further include a bracket assembly 300, which is disposed in the housing 100. The bracket assembly 300 is provided with a light source cavity 31. The inner wall of the light source cavity 31 is provided with a heat dissipation medium inlet 312 and a heat dissipation medium outlet 313, so that the heat dissipation medium can flow through the light source cavity 31. Accordingly, the lamp tube 21 can be at least partially disposed in the light source cavity 31, and the surrounding portion 221 of the reflective component 22 can also be disposed in the light source cavity 31. Thus, the light source cavity 31 can provide certain protection for the lamp tube 21 and the surrounding portion 221. For example, the surrounding portion 221 can be prevented from being deformed by squeezing, colliding, etc. with other components or foreign objects outside the light source cavity 31, so as to ensure that the angle of the light reflected by the surrounding portion 221 is more accurate and reliable, and finally the light output of the skin treatment device is more controllable; the light source cavity 31 is also used to form a heat dissipation channel for the light output component 200.

[0047] In some embodiments, the heat dissipation medium outlet 313 can be located at one end of the lamp tube 21 in the length direction, and the heat dissipation medium inlet 312 can be located at the other end of the lamp tube 21 in the length direction, so that the heat dissipation medium can flow through the surrounding portion 221 along the length direction of the lamp tube 21 to dissipate heat to the surrounding portion 221 and the lamp tube 21.

[0048] It should be noted that the directions of the heat dissipation medium inlet 312 and the heat dissipation medium outlet 313 may be the same as or different from the length direction of the lamp tube 21 , and the embodiment of the utility model does not limit this.

[0049] In some embodiments, the reflective component 22 further includes a first limiting portion 222 disposed on the first side 2211. The first limiting portion 222 is located between a side of the first side 2211 away from the second side 2212 and the inner wall of the light source cavity 31, so that a side of the first side 2211 away from the second side 2212 and the inner wall of the light source cavity 31 are spaced apart, so that a heat dissipation space 311 for the heat dissipation medium to flow is formed between the side of the surrounding portion 221 where the first side 2211 is located and the inner wall of the light source cavity 31.

[0050] Specifically, the first limiting portion 222 can be abutted against the inner wall of the light source cavity 31, or the first limiting portion 222 can have a small gap with the inner wall of the light source cavity 31. In this way, by setting the first limiting portion 222, the outer wall of the surrounding portion 221 on the side where the first side edge 2211 is located can be spaced apart from the inner wall of the light source cavity 31, so as to form a larger heat dissipation space 311 between the outer wall of the surrounding portion 221 on the side where the first side edge 2211 is located and the inner wall of the light source cavity 31.

[0051] In this way, by setting the first limiting portion 222, a larger heat dissipation space 311 can be formed between the outer wall of the surrounding portion 221 on the side where the first side edge 2211 is located and the inner wall of the light source cavity 31. Because the heat dissipation space 311 is located in the light source cavity 31, more air medium can flow into the heat dissipation space 311, thereby increasing the contact area between the outer wall of the surrounding portion 221 on the side where the first side edge 2211 is located and the heat dissipation medium, thereby improving the heat dissipation effect.

[0052] Furthermore, in order to simplify the structure and reduce the number of turns of the heat dissipation medium, one end of the heat dissipation space 311 may be connected to the heat dissipation medium inlet 312 , and the other end may be connected to the heat dissipation medium outlet 313 .

[0053] Next, the technical solution of the embodiment of the utility model is described with examples in combination with the first limiting portion 222 .

[0054] In some embodiments, the first limiting portion 222 is bent and connected to the first side edge 2211. Therefore, the first limiting portion 222 and the surrounding portion 221 can be an integrally formed structure, so as to improve the assembly efficiency by reducing the parts required to be assembled during the assembly process of the skin treatment device, and can also improve the connection strength between the first limiting portion 222 and the surrounding portion 221, and can improve the structural strength of the reflective component 22.

[0055] Exemplarily, the first limiting portion 222 is formed by bending and extending the first side edge 2211 in a direction away from the second side edge 2212, so that the first limiting portion can be prevented from affecting the reflective surface of the surrounding portion 221. For example, the first limiting portion 222 and the surrounding portion 221 can be formed by a bending process. Of course, in some other embodiments, the first limiting portion 222 and the surrounding portion 221 can also be integrally formed by a powder metallurgy process or an injection molding process, and the embodiment of the utility model is not limited to this.

[0056] In some embodiments, the first limiting portion 222 is a strip structure extending along the first side 2211, so that the heat dissipation space 311 is also extended along the first side 2211, thereby making the heat dissipation space 311 longer or larger to improve the heat dissipation effect. For example, the first limiting portion 222 can be a flange formed on the first side 2211.

[0057] Of course, in some other embodiments, there may be more than one first limiting portion 222, and the first limiting portions 222 may be arranged along the length direction of the first side edge 2211. For example, the first limiting portion 222 may include a plurality of folded ears formed on the first side edge 2211.

[0058] Along the length direction of the lamp tube 21, the ratio of the total length of the first limiting portion 222 to the length of the first side 2211 can be greater than or equal to 0.8. Therefore, since the overall length of the first limiting portion 222 is relatively long, a good limiting effect can be provided for each position of the first side 2211 along the length direction. In addition, it can be understood that the lamp tube 21 will generate a large amount of heat when it is working. After the surrounding portion 221 absorbs the heat, part of the heat will be transferred to the first limiting portion 222. That is to say, by making the ratio of the total length of the first limiting portion 222 to the length of the first side 2211 greater than or equal to 0.8, the effect of heat dissipation through the first limiting portion 222 can be improved, and the heat dissipation medium entering the heat dissipation space 311 can be kept flowing in the heat dissipation space 311 as much as possible, thereby improving the heat dissipation efficiency of the light output component 200.

[0059] For example, along the length direction of the lamp tube 21, the ratio of the total length of the first limiting portion 222 to the length of the first side 2211 can be 0.8, 0.812, 0.815, 0.823, 0.83, 0.835, 0.845, 0.85, 0.867, 0.874, 0.88, 0.894, 0.9, 0.92, 0.934, 0.941, 0.95, 0.974, 0.981, 1, 1.05, 1.1, 1.15, 1.2 or 1.25, etc., and the embodiments of the present invention are not limited to this.

[0060] In some other embodiments, the ratio of the total length of the first limiting portion 222 to the length of the first side edge 2211 is preferably 0.9-1.1, so as to improve the heat dissipation effect as much as possible.

[0061] In some embodiments, the angle between the cut surface of the first side edge 2211 and the first limiting portion 222 is greater than or equal to 90 degrees and less than or equal to 95 degrees. This is conducive to miniaturization design.

[0062] For example, the angle between the cross section of the first side 2211 and the first limiting portion 222 can be 90 degrees, 90.5 degrees, 91.4 degrees, 92.3 degrees, 92.5 degrees, 93 degrees, 93.41 degrees, 93.98 degrees, 94 degrees, 94.5 degrees, 94.78 degrees or 95 degrees, which is not limited to the embodiments of the present invention.

[0063] In some embodiments, the inner wall of the light source cavity 31 includes a first inner wall 321. The first inner wall 321 is located on the side of the first side 2211 away from the second side 2212. Therefore, it can also be understood that the heat dissipation space 311 is formed between the first inner wall 321 and the surrounding portion 221.

[0064] The first inner wall 321 can be spaced apart from the first position-limiting portion 222. Thus, it can be prevented that the first inner wall 321 contacts the first position-limiting portion 222 during assembly or use, thereby preventing the surrounding portion 221 from being squeezed and deformed. Furthermore, it can be prevented that the angle of light reflected by the deformed surrounding portion 221 is uncontrollable, thereby causing uneven light emission from the light emitting area 11, and it can also be prevented that the light reflected by the deformed surrounding portion 221 to the light emitting area 11 is reduced, thereby reducing the energy of the light emitting area 11.

[0065] When the first inner wall 321 and the first limiting portion 222 are spaced apart, the gap between the first inner wall 321 and the first limiting portion 222 is less than or equal to 0.4 mm. Thus, it is possible to prevent the surrounding portion 221 from being squeezed and deformed by the first limiting portion 222, and to control the shape and position of the surrounding portion 221 by the first limiting portion 222, so as to limit the displacement distance and deformation amplitude of the surrounding portion 221 when the surrounding portion 221 is accidentally displaced or deformed, thereby making the light output of the light output component 200 more stable and reliable, and also ensuring or improving the heat dissipation effect.

[0066] For example, the gap between the first inner wall 321 and the first limiting portion 222 can be 0.05 mm, 0.08 mm, 0.1 mm, 0.13 mm, 0.15 mm, 0.19 mm, 0.2 mm, 0.25 mm, 0.27 mm, 0.3 mm, 0.312 mm, 0.339 mm, 0.35 mm, 0.381 mm or 0.4 mm, etc., and the embodiments of the present utility model are not limited to this.

[0067] Alternatively, the first inner wall 321 can also abut against the first limiting portion 222, so that the first inner wall 321 can provide a certain support to the surrounding portion 221 through the first limiting portion 222 to prevent the surrounding portion 221 from shaking during use and causing uneven light emission in the light emitting area 11, incorrect light emission angle, etc.

[0068] It can also be understood that no matter whether the first limiting portion 222 and the first inner wall 321 are in contact with or spaced apart from each other, the first limiting portion 222 can guide the heat dissipation medium well. Combined with the above-mentioned heat dissipation medium inlet and heat dissipation medium outlet, they are respectively at different ends in the length direction of the lamp tube 21.

[0069] Then, assuming that the lamp tube 21 is extended along the width direction of the outer shell 100, the first limiting portion 222 and the surrounding portion 221 are also extended along the width direction of the outer shell 100, the heat dissipation medium can flow from the heat dissipation medium inlet to one end of the surrounding portion 221, and then a part of the heat dissipation medium flows from the inside of the surrounding portion 221 along the width direction of the outer shell 100, and a part of the heat dissipation medium flows from the outside of the surrounding portion 221 (including but not limited to the above-mentioned heat dissipation space 311) along the width direction of the outer shell 100, and finally discharged from the heat dissipation medium outlet to achieve heat dissipation of the light output component 200.

[0070] Please continue to refer to Figure 5 , Figure 5 for Figure 2 Schematic diagram of the matching structure of the light emitting component and the bracket component of the skin treatment device shown. In some embodiments, the bracket component 300 also includes a second limiting portion 3211, which is convexly arranged on the first inner wall 321. The second limiting portion 3211 is located on the side of the first limiting portion 222 away from the light emitting area 11, so that a first heat dissipation channel is formed between the first limiting portion 222, the first inner wall 321, the second limiting portion 3211 and the outer surface of the surrounding portion 221. Thus, through the cooperation of the first limiting portion 222 and the second limiting portion 3211, better limiting can be provided for more positions of the surrounding portion 221. Furthermore, on the one hand, the shape and position tolerance of the surrounding portion 221 can be improved to improve the light emitting quality of the light emitting area 11; on the other hand, it can ensure that more positions on the outer surface of the surrounding portion 221 and the inner wall of the light source cavity 31 form a gap (including but not limited to the first heat dissipation channel), so that the contact area between the surrounding portion 221 and the heat dissipation medium in the light source cavity 31 is larger to improve the heat dissipation efficiency.

[0071] In some embodiments, the first inner wall 321 is extended in a direction away from the light exiting area. The angle between the second limiter 3211 and the first inner wall 321 is greater than or equal to 85 degrees and less than or equal to 95 degrees. Thus, the second limiter 3211 is substantially perpendicular to the first inner wall 321, so as to facilitate demolding when the second limiter 3211 is formed by injection molding.

[0072] For example, the angle between the second limiting portion 3211 and the first inner wall 321 may be 85 degrees, 87.2 degrees, 89 degrees, 90 degrees, 91.4 degrees, 92 degrees, 92.5 degrees, 94 degrees or 95 degrees, which is not limited in the embodiments of the present invention.

[0073] In some embodiments, the second position-limiting portion 3211 may be spaced apart from the surrounding portion 221. Thus, it is possible to avoid the second position-limiting portion 3211 from contacting the surrounding portion 221 and squeezing and deforming the surrounding portion 221. Furthermore, it is possible to prevent the angle of light reflected by the deformed surrounding portion 221 from being uncontrollable, thereby causing uneven light emission from the light emitting area 11, and it is also possible to prevent the light reflected by the deformed surrounding portion 221 from being reduced to the light emitting area 11, thereby reducing the amount of light emitted from the light emitting area 11.

[0074] When the second position-limiting portion 3211 and the surrounding portion 221 are spaced apart, the gap between the second position-limiting portion 3211 and the surrounding portion 221 is less than or equal to 0.4 mm. Thus, it is possible to prevent the surrounding portion 221 from being squeezed and deformed by the second position-limiting portion 3211, and to control the shape and position of the surrounding portion 221 by the second position-limiting portion 3211, so as to limit the displacement distance and deformation amplitude of the surrounding portion 221 when the surrounding portion 221 is accidentally displaced or deformed, thereby making the light output of the light output assembly 200 more stable and reliable.

[0075] For example, the gap between the second limiting portion 3211 and the surrounding portion 221 can be 0.05 mm, 0.08 mm, 0.1 mm, 0.13 mm, 0.15 mm, 0.19 mm, 0.2 mm, 0.25 mm, 0.27 mm, 0.3 mm, 0.312 mm, 0.339 mm, 0.35 mm, 0.381 mm or 0.4 mm, etc., and the embodiments of the present utility model are not limited to this.

[0076] Alternatively, the second limiting portion 3211 and the surrounding portion 221 can abut against each other, so that the first inner wall 321 can provide a certain support to the surrounding portion 221 through the second limiting portion 3211 to prevent the surrounding portion 221 from shaking during use and causing uneven light emission in the light emitting area 11, incorrect light emission angle, etc.

[0077] In some embodiments, the second limiting portion 3211 is at least partially located between the surrounding portion 221 and the first inner wall 321 to limit the displacement or deformation of the surrounding portion 221 toward the first inner wall 321 and / or to limit the displacement or deformation of the surrounding portion 221 toward the direction away from the light output area 11.

[0078] That is to say, the second position limiting portion 3211 may be used only to limit the displacement or deformation of the surrounding portion 221 toward the first inner wall 321, the second position limiting portion 3211 may be used only to limit the displacement or deformation of the surrounding portion 221 toward the direction away from the light emitting area 11, or the second position limiting portion 3211 may be used to simultaneously limit the displacement or deformation of the surrounding portion 221 toward the first inner wall 321 and toward the direction away from the light emitting area 11.

[0079] In some embodiments, the surrounding portion 221 has a farthest end away from the light exiting region 11. The second limiting portion 3211 is located between the first side edge 2211 and the farthest end. In this way, heat dissipation channels can be formed on both sides of the second limiting portion 3211 to improve the heat dissipation effect; moreover, in this way, the second limiting portion 3211 can also be used to simultaneously limit the displacement or deformation of the surrounding portion 221 in the direction close to the first inner wall 321 and in the direction away from the light exiting region 11.

[0080] Then, assuming that the light exit area 11 is on the left side of the surrounding portion 221, the right end of the surrounding portion 221 forms the farthest end, and the first inner wall 321 is located at the lower side of the surrounding portion 221. At this time, the second limiting portion 3211 can be located at the lower right side of the surrounding portion 221.

[0081] The free end of the second limiting portion 3211 can be provided with a supporting surface that is adapted to the outer side surface shape of the surrounding portion 221, thereby increasing the matching area between the second limiting portion 3211 and the surrounding portion 221, so as to improve the limiting effect of the second limiting portion 3211 and make the surrounding portion 221 more evenly stressed when the supporting surface of the second limiting portion 3211 contacts the surrounding portion 221.

[0082] Specifically, the surrounding portion 221 is an arc-shaped structure, and the supporting surface of the second limiting portion 3211 can be optionally an arc surface, so that the second limiting portion 3211 can be used to simultaneously limit the displacement or deformation of the surrounding portion 221 in the direction close to the first inner wall 321 and in the direction away from the light output area 11.

[0083] It should be noted that, as mentioned above, the second position-limiting portion 3211 may be spaced apart from or abutted against the surrounding portion 221. Then, when the second position-limiting portion 3211 and the surrounding portion 221 are spaced apart from each other, the supporting surface of the second position-limiting portion 3211 may be used to support the surrounding portion 221 when the surrounding portion 221 is deformed or displaced; when the second position-limiting portion 3211 abuts against the surrounding portion 221, the second position-limiting portion 3211 may abut against the surrounding portion 221 through the supporting surface.

[0084] In some embodiments, the second position limiting portion 3211 is a strip-shaped structure extending along the length direction of the lamp tube 21. Alternatively, there may be multiple second position limiting portions 3211, which are arranged along the length direction of the lamp tube 21.

[0085] Along the length direction of the lamp tube 21, the ratio of the total length of the second limiting portion 3211 to the length of the first side 2211 is greater than or equal to 0.8. Therefore, due to the long overall length of the second limiting portion 3211, a good limiting effect can be provided for each position of the surrounding portion 221 along the length direction of the lamp.

[0086] For example, along the length direction of the lamp tube 21, the ratio of the total length of the second limiting portion 3211 to the length of the first side 2211 can be 0.8, 0.812, 0.815, 0.823, 0.83, 0.835, 0.845, 0.85, 0.867, 0.874, 0.88, 0.894, 0.9, 0.92, 0.934, 0.941, 0.95, 0.974, 0.981 or 1, etc., and the embodiments of the present invention are not limited to this.

[0087] In some embodiments, the second position-limiting portion 3211 is set to be reduced in the protruding direction. Thus, the connection strength between the second position-limiting portion 3211 and the inner wall of the light source cavity 31 can be ensured, and the second position-limiting portion 3211 can be made smaller as a whole. Accordingly, a larger space can be reserved between the inner wall of the light source cavity 31 and the outer surface of the surrounding portion 221, so that the outer surface of the surrounding portion 221 is in full contact with the heat dissipation medium, thereby improving the heat dissipation effect.

[0088] In addition, taking the bracket assembly 300 as an example of being injection molded, the second limit portion 3211 being reduced in the convex direction can also be understood as the surface of the second limit portion 3211 having a draft angle, thereby facilitating demoulding of the second limit portion 3211 after injection molding. Of course, in some other embodiments, the bracket assembly 300 may not be injection molded, and the embodiment of the utility model is not limited to this.

[0089] As mentioned above, the side of the first side 2211 away from the second side 2212 is spaced apart from the inner wall of the light source cavity 31, so that the surrounding portion 221 forms a heat dissipation space 311 for the heat dissipation medium to flow between the side where the first side 2211 is located and the inner wall of the light source cavity 31. Then, the heat dissipation space 311 can have a maximum position where the distance from the surrounding portion 221 is the largest, and the second limiting portion 3211 is arranged close to the maximum position, which can largely avoid the influence of the second limiting portion 3211 on the flow of the heat dissipation medium in the heat dissipation space 311, thereby improving or ensuring the heat dissipation effect.

[0090] In some embodiments, the bracket assembly 300 may further include at least one third limiting portion 331. The third limiting portion 331 is at least partially located on a side of the surrounding portion 221 away from the light outlet 2213 to limit displacement or deformation of the surrounding portion 221 away from the light outlet region 11.

[0091] For example, the third position limiting portion 331 may be convexly provided on the first inner wall 321, or the third position limiting portion 331 may be convexly provided on the inner wall of the light source cavity 31 on the side away from the light outlet 2213 of the surrounding portion 221, and the embodiment of the utility model is not limited thereto. Thus, the third position limiting portion 331 may further improve the position limiting or position control effect of the surrounding portion 221.

[0092] In some embodiments, the third position-limiting portion 331 may be spaced apart from the surrounding portion 221. Thus, it is possible to avoid the third position-limiting portion 331 from contacting the surrounding portion 221 and squeezing and deforming the surrounding portion 221. Furthermore, it is possible to prevent the angle of light reflected by the deformed surrounding portion 221 from being uncontrollable, thereby causing uneven light emission from the light emitting area 11, and it is also possible to prevent the light reflected by the deformed surrounding portion 221 from being reduced to the light emitting area 11, thereby reducing the amount of light emitted from the light emitting area 11.

[0093] When the third limiting portion 331 and the surrounding portion 221 are spaced apart, the gap between the third limiting portion 331 and the surrounding portion 221 is less than or equal to 0.4 mm. Thus, it is possible to prevent the surrounding portion 221 from being squeezed and deformed by the third limiting portion 331, and to control the shape and position of the surrounding portion 221 by the third limiting portion 331, so as to limit the displacement distance and deformation amplitude of the surrounding portion 221 when the surrounding portion 221 is accidentally displaced or deformed, thereby making the light output of the light output assembly 200 more stable and reliable.

[0094] For example, the gap between the third limiting portion 331 and the surrounding portion 221 can be 0.05 mm, 0.08 mm, 0.1 mm, 0.13 mm, 0.15 mm, 0.19 mm, 0.2 mm, 0.25 mm, 0.27 mm, 0.3 mm, 0.312 mm, 0.339 mm, 0.35 mm, 0.381 mm or 0.4 mm, etc., and the embodiments of the present utility model are not limited to this.

[0095] Alternatively, the third limiting portion 331 and the surrounding portion 221 can abut against each other, so that the inner wall of the light source cavity 31 can provide certain support to the surrounding portion 221 through the third limiting portion 331 to prevent the surrounding portion 221 from shaking during use and causing uneven light emission from the light emitting area 11, incorrect light emission angle, etc.

[0096] In some embodiments, the third limiting portion 331 can be a sheet-like or columnar structure, so that the volume of the third limiting portion 331 can be reduced, so that there can be a larger space between the side of the surrounding portion 221 away from the light output area 11 and the inner wall of the light source cavity 31 for the heat dissipation medium to flow, thereby improving the heat dissipation effect.

[0097] In some embodiments, the second side edge 2212 of the surrounding portion 221 may be in contact with the inner wall of the light source cavity 31 , thereby providing a better supporting effect for the surrounding portion 221 .

[0098] Then, in combination with the above-mentioned first limiting portion 222 which can be spaced apart from the inner wall of the light source cavity 31, the second limiting portion 3211 and the third limiting portion 331 can also be spaced apart from the surrounding portion 221. Therefore, taking the second side edge 2212 being located on the upper side of the first side edge 2211 as an example, it can be understood that the upper side of the surrounding portion 221 abuts against the inner wall of the light source cavity 31, so that the inner wall of the light source cavity 31 provides a certain support to the surrounding portion 221, and at the same time, the lower half of the surrounding portion 221 will not be squeezed and deformed by the inner wall of the light source cavity 31, so that the angle of the light reflected by the surrounding portion 221 is more accurate, thereby improving the light output quality of the light output area 11, and also forming a larger heat dissipation space 311 between the lower half of the surrounding portion 221 and the lower inner wall of the light source cavity 31, so as to increase the contact area between the heat dissipation medium and the surrounding portion 221 and improve the heat dissipation effect.

[0099] like Figure 3 As shown, in some embodiments, the reflective component 22 further includes a side reflective portion 223. The side reflective portion 223 is provided at at least one end of the surrounding portion 221 to reflect at least part of the light in the surrounding portion 221 to be emitted from the light outlet 2213. Thus, the side reflective portion 223 can reduce or even eliminate the light emitted from both ends of the surrounding portion 221, so that more light generated by the lamp tube 21 is emitted from the light outlet 2213 to the light outlet area 11, and finally the energy at the light outlet area 11 is increased to improve the treatment effect of the skin treatment device.

[0100] The number of the side reflective portions 223 may be one, or may be multiple such as two, three, four or five, which is not limited in the embodiment of the present utility model.

[0101] For example, the number of the side reflective portions 223 is two, and one side reflective portion 223 is provided at each end of the surrounding portion 221 .

[0102] It is understandable that the side reflective portion 223 may be an opening that completely closes the end of the surrounding portion 221 , or may be an opening that only partially covers the end of the surrounding portion 221 , and the embodiment of the utility model is not limited to this.

[0103] For example, along the direction from the first side edge 2211 to the second side edge 2212 , both ends of the side reflective portion 223 are connected and fixed to the surrounding portion 221 , so that the light output at the light outlet 2213 can be increased by the larger side reflective portion 223 .

[0104] Specifically, along the direction from the first side edge 2211 to the second side edge 2212, one end of the side reflective portion 223 may be connected to the surrounding portion 221, and the other end may be clipped to the surrounding portion 221; for example, the side reflective portion 223 and the surrounding portion 221 are integrally formed through a bending process, and then the free end of the side reflective portion 223 is also clipped to the surrounding portion 221.

[0105] Optional, please continue to refer to Figure 6 , Figure 6 for Figure 2 A schematic diagram of the structure of the second light-emitting component of the skin treatment device shown. Along the direction from the first side edge 2211 to the second side edge 2212. The side reflector 223 is connected to one side of the surrounding portion 221, and is spaced from the other side to form an end vent 224 for the heat dissipation medium to flow into or out of the surrounding portion 221. Thus, the light output amount or energy at the light outlet 2213 can be increased through the side reflector 223, and more heat dissipation medium can be allowed to flow into or out of the surrounding portion 221 through the end vent 224, so as to improve the heat dissipation effect of the inner surface of the surrounding portion 221 and the portion of the lamp tube 21 located in the surrounding portion 221.

[0106] That is to say, in the embodiment of the utility model, a side reflective portion 223 is provided in the area near the first side edge 2211 in the opening at the end of the surrounding portion 221 for reflection, and an end air outlet 224 is formed on the side near the second side wall 3342 in the opening at the end of the surrounding portion 221, so that the end of the surrounding portion 221 can take into account both increasing the amount of light output or energy and improving the heat dissipation effect.

[0107] In some embodiments, the ratio of the width h of the end vent 224 to the width H of the surrounding portion 221 along the direction from the first side 2211 to the second side 2212 is greater than 0.4 and less than or equal to 0.8. In this way, the side reflective portion 223 can reflect more light and ensure that more heat dissipation medium can pass through the end vent 224.

[0108] For example, along the direction from the first side 2211 to the second side 2212, the ratio of the width of the end air outlet 224 to the width of the surrounding portion 221 may be greater than 0.41, 0.439, 0.45, 0.497, 0.5, 0.55, 0.59, 0.65, 0.698, 0.7, 0.75 or 0.8. Those skilled in the art may design it by themselves according to the requirements of reflection and heat dissipation, and the embodiments of the utility model are not limited to this.

[0109] In some embodiments, a mounting hole 226 is further formed between the side of the side reflector 223 facing away from the light emitting area 11 and the surrounding portion 221. The lamp tube 21 is inserted into the mounting hole 226. The end tuyere 224 is connected to the mounting hole 226, and the width of the end tuyere 224 is greater than the diameter of the lamp tube 21, so that the lamp tube 21 can enter or leave the mounting hole 226 from the end tuyere 224.

[0110] Specifically, the outer peripheral side of the lamp tube 21 is spaced apart from the periphery of the mounting hole 226 , so that the heat dissipation medium can flow therethrough to improve the heat dissipation effect.

[0111] Therefore, in the actual assembly process, if Figure 8 As shown, after fixing the lamp tube 21, the light outlet 2213 of the surrounding part 221 is directed toward the lamp tube 21 and the end vents 224 at both ends of the surrounding part 221 are directly facing the lamp tube 21, and then the surrounding part 221 is rotated forwardly around the lamp tube 21 as a whole, so that the lamp tube 21 enters the mounting hole 226 from the end vents 224 of the surrounding part 221, and finally the surrounding part 221 is arranged around the lamp tube 21. Conversely, if the surrounding part 221 needs to be disassembled, the surrounding part 221 can be removed from the lamp tube 21 by rotating it in the opposite direction around the lamp tube 21.

[0112] For example, please continue to refer to Figure 7 , Figure 7 for Figure 6 The skin treatment device may further include a circuit board 41 and a conductive bracket 42 mounted on the circuit board 41. The conductive bracket 42 is connected to the lamp tube 21 so that the lamp tube 21 is fixed to the circuit board 41 and electrically connected to the circuit board 41.

[0113] In some embodiments, the end air outlet 224 is located between the circuit board 41 and the side reflective portion 223 , so as to avoid interference between the conductive bracket 42 and the side reflective portion 223 or avoid ionization.

[0114] Then, please continue to refer to Figure 8 , Figure 8 for Figure 7 A schematic diagram of an assembly method of the light emitting assembly is shown. Taking the circuit board 41 located on the upper side of the lamp tube 21 as an example, the surrounding portion 221 can be moved to the lower side of the lamp tube 21 with the light outlet 2213 facing upward, and the end air outlet 224 is arranged directly opposite the lamp tube 21. Then, the surrounding portion 221 is rotated upward around the lamp tube 21, so that the surrounding portion 221 is rotated to surround the lamp tube 21.

[0115] It can also be understood that the circuit board 41 can be located outside the light source cavity 31, and then the conductive bracket 42 can be passed through the bracket assembly 300, so that during the assembly process, at least a portion of the bracket assembly 300 can be assembled with the circuit board assembly 400 first, and then the welding of the lamp tube 21 and the conductive bracket 42 and the installation of the surrounding portion 221 can be completed in sequence, so that the light emitting assembly 200 has the advantage of easy assembly.

[0116] In some embodiments, the first side edge 2211 is located on the side of the second side edge 2212 away from the circuit board 41, so that the first limiting portion 222 is located on the side of the surrounding portion 221 away from the circuit board 41. Furthermore, taking the surrounding portion 221 being installed by rotating in the counterclockwise direction as an example, in the counterclockwise direction, the second side edge 2212 is inserted as the front end between the lamp tube 21 and the inner wall of the light source cavity 31. At this time, since the first limiting portion 222 is not provided on the outer surface of the second side edge 2212, one end of the second side edge 2212 of the surrounding portion 221 is less likely to interfere with the inner wall of the light source cavity 31, thereby facilitating guiding the entire surrounding portion 221 to surround the outer peripheral side of the lamp tube 21 during the rotation process.

[0117] In some embodiments, along the direction from the first side 2211 to the second side 2212 , a portion of the side edge of the side reflector 223 away from the end air outlet 224 is connected to the surrounding portion 221 , and another portion of the side edge is abutted against or spaced from the surrounding portion 221 .

[0118] Then, continuing to take the example that the surrounding portion 221 and the side reflective portion 223 are formed by the bending process, the side reflective portion 223 may be formed by bending at the connection between a part of the side edge of the side reflective portion 223 away from the end air outlet 224 (for example, a part of the lower side edge) and the surrounding portion 221. Correspondingly, a part of the side edge of the side reflective portion 223 away from the end air outlet 224 (for example, another part of the lower side edge) is not bent and connected to the surrounding portion 221. Therefore, by reducing the area where the side edge is connected to the surrounding portion 221, the internal stress formed by the side edge can be effectively reduced during the bending process of the reflective component 22, so as to improve the bending quality of the reflective component 22 and reduce the difficulty of forming.

[0119] In some embodiments, the surrounding portion 221 includes a flat portion, and the curvature of the flat portion is smaller than the curvature of the portion of the surrounding portion 221 away from the light exit area 11. A portion of the side edge of the side reflective portion 223 away from the end air outlet 224 is connected to the flat portion. Furthermore, because the curvature of the flat portion is smaller, when the sheet metal is bent to form the surrounding portion 221, the stress formed at the connection between the side reflective portion 223 and the surrounding portion 221 is also smaller, so as to reduce the difficulty of forming the reflective component 22 and improve the forming quality of the reflective component 22.

[0120] For example, the portion of the surrounding portion 221 that forms the first side edge 2211 may be the aforementioned flat portion.

[0121] Exemplarily, the side edge of the side reflector 223 facing the lamp tube 21 is an arc-shaped edge. Thus, the width of the side reflector 223 is at least partially reduced from the free end to the surrounding portion 221. Thus, compared to the side edge of the side reflector 223 facing the lamp tube 21 being a straight edge, the arc-shaped edge means that the side reflector 223 can be closer to the lamp tube 21, thereby increasing the area of ​​the side reflector 223, thereby effectively improving the reflection ability of the side reflector 223, and ultimately improving the energy of the skin treatment device.

[0122] The width of the end of the side reflective portion 223 away from the end air outlet 224 may be greater than the width of the free end of the side reflective portion 223, and the end of the side reflective portion 223 away from the end air outlet 224 is provided with a through hole 2231. The through hole 2231 is communicated with the inner side of the surrounding portion 221. Therefore, the through hole 2231 can not only reduce the internal stress formed by the reflective component 22 during the bending process to improve the molding quality, but also serve as a heat dissipation hole to allow more heat dissipation medium to flow into or out of the surrounding portion 221 for heat dissipation.

[0123] In some embodiments, the area of ​​the through hole 2231 is less than or equal to 4 square millimeters. For example, the area of ​​the through hole 2231 can be 4 square millimeters, 3.9 square millimeters, 3.55 square millimeters, 3.14 square millimeters, 3 square millimeters, 2.94 square millimeters, 2.5 square millimeters, 2 square millimeters, 1.77 square millimeters, 1.5 square millimeters, 1.43 square millimeters, 1.2 square millimeters, 1 square millimeter, 0.75 square millimeter, 0.5 square millimeter, 0.32 square millimeter or 0.25 square millimeter, etc. Thus, it can be avoided that the through hole 2231 is too large to reduce the amount of light emitted by the side reflective portion 223.

[0124] In some embodiments, the area of ​​the through hole 2231 is greater than or equal to 0.25 square millimeters and less than or equal to 2.5 square millimeters. Thus, it is possible to avoid the through hole 2231 being too small to achieve the heat dissipation effect, and to avoid the through hole 2231 being too large to reduce the emission capacity of the side reflector 223.

[0125] In some embodiments, the through hole 2231 is located at the middle of the end of the side reflector 223 away from the end air outlet 224 in the circumferential direction of the lamp tube 21. Therefore, during the bending process of the reflective component 22, the through hole 2231 can well prevent excessive internal stress from being formed between the side edge of the side reflector 223 away from the end air outlet 224 and the surrounding portion 221, and ultimately the molding quality of the reflective component 22 can be improved.

[0126] In some embodiments, the through hole 2231 may be partially formed in the side reflective portion 223 and partially formed in the surrounding portion 221 to further reduce internal stress. Of course, the through hole 2231 may also be entirely formed in the side reflective portion 223, which is not limited in the embodiment of the utility model.

[0127] Exemplarily, the side reflective portion 223 may include a first portion 2232 and a second portion 2233. The first portion 2232 is extended along the first side edge 2211 toward the second side edge 2212, and the side of the first portion 2232 close to the first side edge 2211 is connected to the surrounding portion 221. An end vent 224 is formed between the side of the first portion 2232 away from the first side edge 2211 and the surrounding portion 221. The second portion 2233 is convexly disposed on the side of the first portion 2232 away from the light exit area 11, and the second portion 2233 is abutted against or spaced from the surrounding portion 221.

[0128] Then, compared to the second portion 2233 which is also formed by bending the edge of the surrounding portion 221, during the bending process of the surrounding portion 221, the second portion 2233 will not be affected by the surrounding portion 221 to form stress, thereby better reducing the difficulty of forming the reflective component 22 and improving the forming quality. Of course, in some other embodiments, the first portion 2232 and the surrounding portion 221 are not bent and connected, and the second portion 2233 is bent and connected to the surrounding portion 221, and the embodiment of the utility model is not limited to this.

[0129] In some embodiments, a mounting hole 226 is formed between the second portion 2233 and the surrounding portion 221, and the mounting hole 226 is at least partially located on a side of the first portion 2232 away from the light exiting area 11. Then, in the direction from the first side edge 2211 toward the second side edge 2212, the length of the first portion 2232 is made larger, thereby effectively increasing the amount of light reflected by the side light reflecting portion 223, and ultimately increasing the energy of the skin treatment device.

[0130] In some embodiments, the width of the side reflector 223 is at least partially reduced from the free end to the surrounding portion 221. In other words, the width of at least a portion of the side reflector 223 is reduced in the direction away from the end air outlet 224. The width of the side reflector 223 is the size of the side reflector 223 in the direction from the light emitting assembly 200 to the light emitting area 11. Thus, at least a portion of the side reflector 223 can be made wider, thereby increasing the area of ​​the side reflector 223, and thus effectively increasing the amount of light reflected by the side reflector 223, and ultimately increasing the energy of the skin treatment device.

[0131] In some embodiments, the side of the second portion 2233 facing the lamp tube 21 is spaced from the lamp tube 21, and the gap between the side of the second portion 2233 facing the lamp tube 21 and the lamp tube 21 is less than or equal to 1 mm. This makes the gap between the side reflector 223 and the lamp tube 21 smaller, which means that the side reflector can be made larger, thereby increasing the reflection energy of the side reflector 223.

[0132] For example, the gap between the second part 2233 and the lamp tube 21 on the side facing the lamp tube 21 is 1 mm, 0.976 mm, 0.95 mm, 0.814 mm, 0.746 mm, 0.7 mm, 0.65 mm, 0.594 mm, 0.5 mm, 0.4 mm, 0.31 mm, 0.25 mm or 0.1 mm, etc., and the embodiments of the utility model are not limited to this.

[0133] In some embodiments, the second portion 2233 is spaced apart from the surrounding portion 221 to form a ventilation gap, and the ventilation gap is connected to the through hole 2231 located at the connection between the second portion 2233 and the first portion 2232. Therefore, the heat dissipation medium can also flow into or out of the surrounding portion 221 from the ventilation gap to further improve the heat dissipation effect in the surrounding portion 221.

[0134] The reflective component 22 further includes a first clamping portion 225 , which is connected and fixed to the surrounding portion 221 , so that the first clamping portion 225 can follow the surrounding portion 221 to rotate around the lamp tube 21 and be detached from or clamped to the bracket assembly 300 .

[0135] As mentioned above, in the actual assembly process, the lamp tube 21 may be fixed first, and then the light outlet 2213 of the surrounding portion 221 may be oriented toward the lamp tube 21 and the end vents 224 at both ends of the surrounding portion 221 may face the lamp tube 21, and then the surrounding portion 221 may be rotated in a positive direction around the lamp tube 21 as a whole, so that the lamp tube 21 may enter the mounting hole 226 from the end vents 224 of the surrounding portion 221, and finally the surrounding portion 221 may be arranged around the lamp tube 21. Conversely, if the surrounding portion 221 needs to be disassembled, the surrounding portion 221 may be rotated in the opposite direction around the lamp tube 21 to be removed from the lamp tube 21.

[0136] Then, when the surrounding portion 221 rotates forward around the lamp tube 21, the first clamping portion 225 is clamped on the bracket assembly 300 to achieve the connection and fixation between the reflective component 22 and the bracket assembly 300. Conversely, when the surrounding portion 221 rotates reversely around the lamp tube 21, the first clamping portion 225 is separated from the bracket assembly 300, so that the reflective component 22 can be disassembled.

[0137] In some embodiments, the first clamping portion 225 protrudes from a side of the surrounding portion 221 away from the light emitting area 11. In the direction from the first side edge 2211 to the second side edge 2212, a first clamping structure 2251 is provided on one side of the first clamping portion 225, and the first clamping structure 2251 is used to follow the surrounding portion 221 to rotate around the lamp tube 21 and be detached from or clamped to the bracket assembly 300.

[0138] Exemplarily, the first engaging structure 2251 includes a first protrusion, and the inner wall of the light source cavity 31 is provided with a first engaging hole 332. The opening direction of the first engaging hole 332 is the same as or opposite to the direction from the first side 2211 to the second side 2212, so as to allow the first protrusion to engage or disengage.

[0139] Please continue to refer to Figure 6 and Fig. 9 , Fig. 9 for Figure 5 Schematic diagram of a partial structure of the bracket assembly shown. In some embodiments, the inner wall of the light source cavity 31 is further provided with a second clamping portion 334. The second clamping portion 334 is used to engage with the first clamping portion 225. For example, when the first clamping structure 2251 includes a first protrusion, the first clamping hole 332 can be formed in the second clamping portion 334. Of course, in some other embodiments, the first clamping structure 2251 can also be a recessed structure for the second clamping portion 334 to be inserted, and the embodiment of the utility model is not limited to this.

[0140] There are two second clamping parts 334. A second clamping part 334 is provided at each axial end of the surrounding part 221 to form a heat dissipation gap between the side of the surrounding part 221 away from the light exit area 11 and the two second clamping parts 334. Thus, the contact area between the outer surface of the surrounding part 221 and the heat dissipation medium can be increased to improve the heat dissipation effect.

[0141] In some embodiments, the inner wall of the light source cavity 31 may include a fifth inner wall 333. The fifth inner wall 333 is located on a side of the surrounding portion 221 away from the light emitting region 11. Next, the reflective component 22 is further described with reference to the fifth inner wall 333.

[0142] The second clamping portion 334 includes a first side wall 3341, a second side wall 3342 and a third side wall 3343. The first side wall 3341 and the second side wall 3342 are arranged at intervals along the length direction of the lamp tube 21. The first side wall 3341 and the second side wall 3342 are both connected to the fifth inner wall 333 on the side away from the light exiting area 11. The first side wall 3341 and the second side wall 3342 are both connected to the third side wall 3343 on the side close to the light exiting area 11, so as to form a first clamping hole 332 between the first side wall 3341, the second side wall 3342, the third side wall 3343 and the fifth inner wall 333. Thus, the first clamping portion 225 and the surrounding portion 221 connected to the first clamping portion 225 can also be restricted from moving along the length direction of the lamp tube 21 through the cooperation between the first side wall 3341 and the second side wall 3342, so as to make the installation of the reflective component 22 more reliable.

[0143] In some embodiments, an installation space is formed between the lamp tube 21 and the fifth inner wall 333 for the surrounding portion 221 to rotate around the lamp tube 21 .

[0144] Then, continuing with the example of the second side wall 3342 being located on the upper side of the first side edge 2211, during the assembly process, at least one end of the first clamping hole 332 is open downward, and the reflective component 22 can be moved to the bottom of the lamp tube 21 with the light outlet 2213 facing upward and the first clamping portion 225 facing downward, and then the second side edge 2212 is first placed in the installation space, so that the second side edge 2212 serves as the front end of the surrounding portion 221 for rotating to rotate the surrounding portion 221 around the lamp tube 21 until the first clamping portion 225 can be connected to the bracket assembly 300, so that the surrounding portion 221 is rotated to be set around the lamp tube 21.

[0145] In some embodiments, the inner wall of the light source cavity 31 (such as the fifth inner wall 333) is further provided with a guide groove 335, one end of which is connected to the first clamping hole 332, and the guide groove 335 is extended along the first side edge 2211 toward the second side edge 2212, so that the first clamping portion 225 follows the surrounding portion 221 to rotate around the lamp tube 21. In the direction away from the first clamping hole 332, the groove width of the guide groove 335 gradually increases.

[0146] Then, during the assembly process, the upper end of the guide groove 335 may be connected to the first clamping hole 332, and the lower end may be wide and the upper end may be narrow. Thus, during the rotation of the surrounding portion 221, the first clamping portion 225 may move from bottom to top along the guide groove 335 to play a guiding role, so that the reflective component 22 can be more accurately installed on the bracket assembly 300.

[0147] The above are some examples of the reflective component 22 in the embodiment of the present utility model. The following will continue to illustrate the technical solution of the embodiment of the present utility model in combination with the bracket assembly 300.

[0148] Please continue to refer to Fig.10 and Fig.11 , Fig.10 for Figure 5 Exploded view of the bracket assembly shown, Fig.11 for Figure 5 Another cross-sectional view of the bracket assembly shown. The bracket assembly 300 may include a first bracket 32 ​​and a second bracket 33. The first bracket 32 ​​is connected and fixed to the second bracket 33 so that a light source cavity 31 is formed between the first bracket 32 ​​and the second bracket 33. Furthermore, by splicing the first bracket 32 ​​and the second bracket 33 to form the light source cavity 31, the molding difficulty of the light source cavity 31 can be reduced. For example, the first bracket 32 ​​and the second bracket 33 may be separately injection molded, and then the first bracket 32 ​​and the second bracket 33 are spliced ​​to form the light source cavity 31.

[0149] In some embodiments, the first clamping portion 225 is clamped with one of the first bracket 32 ​​and the second bracket 33, and the reflective component 22 is not in contact with the other of the first bracket 32 ​​and the second bracket 33. Thus, it is possible to avoid deformation of the reflective component 22 caused by the first bracket 32 ​​and the second bracket 33 being squeezed together, thereby ensuring the accuracy and reliability of the angle of light reflected by the surrounding portion 221, thereby improving the light output quality of the skin treatment device.

[0150] Exemplarily, the first bracket 32 ​​may include a first inner wall 321, a second inner wall 322, and a third inner wall 323. The first inner wall 321 extends along the length direction of the lamp tube 21, and the second inner wall 322 and the third inner wall 323 are respectively located at both ends of the first inner wall 321 in the length direction of the lamp tube 21. The second bracket 33 is connected with the first bracket 32, and the second bracket 33 includes a fourth inner wall 336 and a fifth inner wall 333 both extending along the length direction of the lamp tube 21, the fourth inner wall 336 is arranged opposite to the first inner wall 321, and the fifth inner wall 333 is arranged opposite to the light emitting area 11, so as to form a light source cavity 31 between the third inner wall 323, the first inner wall 321, the second inner wall 322, the fourth inner wall 336, and the fifth inner wall 333.

[0151] Furthermore, when the first bracket 32 ​​and the second bracket 33 are injection molded, for example, the first bracket 32 ​​can be easily demoulded from any side that should be covered by the fourth inner wall 336 and the fifth inner wall 333 after injection molding, and the second bracket 33 can be easily demoulded from any side that should be covered by the first inner wall 321, the second inner wall 322 and the third inner wall 323, so that the bracket assembly 300 has the advantage of being easier to manufacture.

[0152] In some embodiments, the angle between the fourth inner wall 336 and the fifth inner wall 333 is an obtuse angle. Thus, compared with the fourth inner wall 336 and the fifth inner wall 333 being arranged at an acute angle, the second bracket 33 is easier to demold after injection molding.

[0153] In some embodiments, the first inner wall 321 is extended in a direction away from the light exit area 11. One end of the first inner wall 321 away from the light exit area 11 is matched and connected with one end of the fifth inner wall 333. The spacing between the surrounding portion 221 and the first inner wall 321 gradually increases in a direction close to the connection between the first inner wall 321 and the fifth inner wall 333, and / or the spacing between the surrounding portion and the fifth inner wall 333 gradually increases in a direction close to the connection between the first inner wall 321 and the fifth inner wall 333, and the second limiting portion 3211 is arranged close to the connection.

[0154] For example, taking the example in which the light-emitting area 11 is located on the left side of the surrounding portion 221 and the first side edge 2211 is located on the lower side of the second side edge 2212, it can be understood that the distance between the surrounding portion 221 and the first inner wall 321 gradually increases from left to right, and the distance between the surrounding portion 221 and the fifth inner wall 333 gradually increases from top to bottom, thereby forming a larger heat dissipation space between the surrounding portion 221 and the inner wall of the light source cavity 31 to allow more heat dissipation medium to flow, thereby improving the heat dissipation effect.

[0155] It should be noted that by assembling the light emitting assembly 200 in the above manner, the lamp tube 21 and the like can be easily fixed. In the solution of forming a heat dissipation space on one side of the reflective component 22, other methods can also be used for assembly, such as first installing the reflective component 22 outside the lamp tube 21 that has been welded to the circuit board 41, and then assembling them together on the bracket assembly 300.

[0156] The above are some examples of the bracket assembly in the embodiment of the present invention.

[0157] The above are some examples of the bracket assembly 300 in the embodiment of the present invention. The following will continue to illustrate the technical solution of the embodiment of the present invention in combination with some other components of the skin treatment device.

[0158] The skin treatment device may further include a cold compress component 500. The cold compress component 500 is disposed at the light exiting area 11 for applying cold compress to the skin.

[0159] The cold compress component 500 may include a first light guide component 51 and a refrigeration sheet 52. The first light guide component 51 is arranged in the light exit area 11. If the light exit area 11 is an open structure, the first light guide component 51 may be arranged in the light exit area 11 to transmit the light emitted by the light exit component 200. The refrigeration sheet 52 is thermally connected to the first light guide component 51. For example, the refrigeration sheet 52 is directly attached to the first light guide component 51 or attached to the first light guide component 51 through a heat-conducting medium such as thermal grease. Furthermore, the first light guide component 51 can be cooled by the refrigeration sheet 52, and the cooled first light guide component 51 is exposed from the light exit area 11 to contact the skin. Therefore, the first light guide component 51 can not only transmit the light of the light source to care for the user's skin, but also be cooled by the refrigeration sheet 52 to provide a cold compress for the user.

[0160] Specifically, the cooling sheet 52 is also called a semiconductor cooling sheet 52. It 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.

[0161] The first light guiding component 51 may be made of sapphire or other light guiding materials, which is not limited in the embodiment of the present utility model.

[0162] Optionally, the cold compress assembly 500 may also include a cold compress (not shown in the figure) and a cooling sheet 52, and the cold compress is arranged on one side / around the light exit area 11. The cooling sheet 52 is thermally connected to the cold compress; for example, the cooling sheet 52 is directly attached to the cold compress or attached to the cold compress through a heat-conducting medium such as thermal grease. Furthermore, the cold compress can be cooled by the cooling sheet 52, and the cooled cold compress is exposed from one side / around the light exit area 11 so that it can contact the skin to provide a cold compress to the user.

[0163] In some embodiments, the skin treatment device may further include a filter component 600. The filter component 600 is disposed between the light output area 11 and the light output component 200, and is used to filter light of a preset wavelength. For example, the filter component 600 is used to transmit light with a wavelength between 560 nanometers and 1200 nanometers, thereby forming an IPL (intense pulsed light) light within a specific wavelength range to irradiate the user's skin. In actual use, the wavelength of light required for hair removal may be between 560 nanometers and 1200 nanometers, and the wavelength of light required for skin rejuvenation may be between 640 nanometers and 1200 nanometers. In this way, the skin care device can have both cold compress and skin rejuvenation functions. Of course, other functions can also be achieved by setting the light output component 200, or the light output component 200 and the filter.

[0164] In some embodiments, the filter assembly 600 and the first light guide component 51 may be arranged sequentially in a direction away from the light output assembly 200. In this way, the skin care device can have the three functions of cold compress, skin rejuvenation, and hair removal at the same time.

[0165] Please continue to refer to Fig.12 , Fig.12 for Figure 2 The partial parts assembly scene diagram of the skin treatment device shown in the figure. It has been submitted above that the bracket assembly 300 may include a first bracket 32 ​​and a second bracket 33. Then, in some embodiments, the cold compress assembly 500 and the filter assembly 600 are configured to be pre-installed on the first bracket 32 ​​to form a first integral component and be integrally installed on the second bracket 33. Therefore, the difficulty of disassembling and assembling the cold compress assembly 500, the filter assembly 600 and the first bracket 32 ​​can be reduced by the integrated disassembly and assembly method.

[0166] In some embodiments, the skin treatment device further includes a circuit board assembly 400 , and the circuit board assembly 400 and the light output assembly 200 can be configured to be pre-installed on the second bracket 33 to form a second integral component and be integrally installed on the first bracket 32 ​​.

[0167] Therefore, the difficulty of disassembling and assembling the circuit board assembly 400, the light output assembly 200 and the second bracket 33 can be reduced through the integrated disassembly and assembly method.

[0168] Please continue to refer to Fig.13 , Fig.13 for Figure 1 A cross-sectional view of the skin treatment device along the AA direction Figure 2 In some embodiments, the skin treatment device may further include a heat dissipation component 700. The heat dissipation component 700 is used to dissipate heat from the light emitting component 200 and / or the cold compress component 500. Then, when the heat dissipation component 700 dissipates heat from the light emitting component 200, it is possible to prevent the light emitting component 200 from being overheated and causing abnormal operation or even damage. When the heat dissipation component 700 dissipates heat from the cold compress component 500, a cold compress can be provided to the skin where hair removal or skin rejuvenation is to be performed, so as to reduce or even eliminate the pain or heat sensation generated during hair removal or skin rejuvenation.

[0169] Exemplarily, the heat dissipation assembly 700 includes a fan 71, which is used to drive the air in the light source cavity 31 to convect with the space outside the housing 100. Therefore, the heat dissipation medium is the air driven by the fan 71 to flow, so as to achieve heat dissipation of the light output assembly 200.

[0170] In some embodiments, the heat dissipation assembly 700 may further include a heat conductive member 72 and a heat sink 73 mounted on the heat conductive member 72. The heat conductive member 72 is thermally connected to the cold compress assembly 500. The fan 71 is also used to drive air to flow through the heat sink 73 for heat dissipation.

[0171] Specifically, the heat conductive member 72 may be a temperature equalizing plate, a heat pipe, or an aluminum plate, etc. The heat conductive member 72 may be directly attached to the cold compress assembly 500, such as the refrigeration sheet 52 of the cold compress assembly 500, or may be attached to the cold compress assembly 500, such as the refrigeration sheet 52 of the cold compress assembly 500, through a heat conductive medium such as thermal grease, so that the heat conductive member 72 is thermally connected to the cold compress assembly 500. Then, the heat on the cold compress assembly 500 can be quickly transferred to the heat conductive member 72 and the heat sink 73, and finally the heat dissipation of the cold compress assembly 500 is achieved.

[0172] In some embodiments, the housing 100 is provided with an air inlet 12 and an air outlet 13. The air inlet 12 is used for allowing air outside the housing 100 to enter the light source cavity 31, and the air outlet 13 is used for allowing air in the light source cavity 31 to flow out of the housing 100, and at least one of the air inlet 12 and the air outlet 13 has an opening direction different from the length direction of the lamp tube 21.

[0173] It is understandable that, since the surrounding portion 221 is disposed around the lamp tube 21, the direction of the opening at the end of the surrounding portion 221 is also the same as the length direction of the lamp tube 21. Therefore, it means that the direction of the opening of at least one of the air inlet 12 and the air outlet 13 is different from the direction of the opening at the end of the surrounding portion 221. Thus, it is possible to reduce or even prevent the light in the surrounding portion 221 from being emitted from the end opening and continuing to be emitted from the air inlet 12 and / or the air outlet 13 to the outside of the housing 100, thereby reducing light leakage at the non-light emitting area 11 of the skin treatment device.

[0174] For example, the housing 100 may be in the shape of an elongated strip, the lamp tube 21 may be arranged to extend along the width direction, and the air outlet 13 and the air inlet 12 may be arranged on one side of the housing 100 in the thickness direction.

[0175] In some embodiments, the housing 100 and the bracket assembly 300 may also form a heat dissipation duct. The light source cavity 31 may be a part of the heat dissipation duct, the inlet of the heat dissipation duct is connected to the air inlet 12, and the outlet of the heat dissipation duct is connected to the air outlet 13. The fan 71 and the heat sink 73 of the heat dissipation assembly 700 are both located in the heat dissipation channel, so that the fan 71 may drive the air in the heat dissipation duct to convect with the air outside the housing 100, thereby dissipating the heat of the light output assembly 200 and the cold compress assembly 500.

[0176] It should be noted that the heat dissipation duct may have multiple branches, and different branches may be completely isolated or partially intersected, which is not limited in the embodiment of the utility model. The light output component 200 and the heat sink 73 may be located in different branches to dissipate heat separately.

[0177] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0178] The skin treatment device provided by the embodiment of the utility model is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation mode of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. At the same time, for technicians in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
