[0026] In some embodiments, the skin care device is a hair removal device or a skin rejuvenation device.

[0027] In some embodiments, the heat dissipation bracket is provided with a support portion for supporting the end of the heat-conducting plate away from the first air vent.

[0028] In some embodiments, the heat dissipation bracket includes a base plate extending along the direction of the fan toward the light outlet. One end of the base plate near the light outlet is located on the side of the light-emitting assembly away from the heat-conducting plate.

[0029] In some embodiments, the heat dissipation bracket further includes an isolation portion located between the light-emitting component and the heat-conducting plate to isolate the light-emitting component from the heat-conducting plate.

[0039] The beneficial effects of the embodiments of this application are as follows:

[0040] Compared to the case where the end of the heat-conducting plate closest to the fan is located in the middle of the first and second sides, in this embodiment, the end of the heat-conducting plate away from the cooling assembly is bent to the first side, allowing more gas flowing through the first air outlet to flow along the heat-conducting plate and then through the heat sink. This improves the heat dissipation effect of the cooling assembly by enhancing the heat dissipation effect of the heat sink, ultimately improving the cooling effect of the skin care device.

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

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0063] This application provides a skin care device, which can be a light-based skin care device, such as a hair removal device or a skin rejuvenation device, so that the skin care device has a light-based care function.

[0064] Phototherapy involves irradiating the skin to be treated with IPL light sources, laser light sources, or LED light sources.

[0065] Of course, skin care devices may also have electrical stimulation functions, making them multifunctional skin care devices with at least phototherapy and electrical stimulation functions. This application does not limit this aspect.

[0066] Electrical stimulation therapy can be performed by applying electrical stimulation currents such as radiofrequency current, intermediate frequency current, and microcurrent (such as EMS current) to the skin to be treated.

[0067] Please refer to Figure 1 and Figure 2 Taking a skin care device with a phototherapy function as an example, the skin care device includes a housing 100 and a light-emitting component 200. The housing 100 is provided with a light-emitting port 11. The light-emitting component 200 is disposed inside the housing 100 and is used to generate light that is emitted from the light-emitting port 11 onto the skin to be treated.

[0068] The light emission port 11 can be located on one end face along the length of the housing 100, or it can be located on the peripheral surface of the housing 100. This application embodiment does not limit this. In this application embodiment, the light emission port 11 can be located on one end face along the length of the housing 100.

[0069] The light-emitting assembly 200 may include a lamp tube 21.

[0070] The lamp tube 21 can be a xenon lamp tube 21, etc., and this application embodiment does not limit it. Of course, in some other embodiments, the light-emitting component 200 may also include a laser light source, etc., and this application embodiment does not limit it either.

[0071] The number of lamp tubes 21 can be one or more, and this application embodiment does not limit this.

[0072] The light-emitting assembly 200 may also include a reflector 22, in which the lamp tube 21 is at least partially disposed. Thus, the reflector 22 can reflect a portion of the light emitted by the lamp tube 21 to the light-emitting port 11, thereby increasing the intensity of the light emitted from the light-emitting port 11.

[0073] In some embodiments, the skin care device also includes a cold compress component 300, which is at least partially disposed at the light outlet 11 for applying a cold compress to the skin to be treated, thereby giving the skin care device a cold compress function.

[0074] For example, the cooling compress assembly 300 includes a cooling element 31 and a light-transmitting element 32. The light-transmitting element 32 is disposed within the light outlet 11. The cooling element 31 and the light-transmitting element 32 are thermally connected. Thus, the cooling compress assembly 300 can apply a cooling compress to the skin to be treated through the cooling element 31.

[0075] The light-transmitting element 32 may include sapphire, glass, acrylic, etc., and this application embodiment does not limit it.

[0076] In some embodiments, the skin care device further includes a heat dissipation assembly 400. The heat dissipation assembly 400 includes a heat-conducting plate 41 and a heat sink 42. The heat sink 42 is connected to the heat-conducting plate 41. The heat-conducting plate 41 is thermally connected to the cooling assembly 300 (such as the cooling element 31 of the cooling assembly 300). Thus, heat from the cooling assembly 300 can be conducted to the heat sink 42 through the heat-conducting plate 41 for rapid heat dissipation through the heat sink 42.

[0077] The heat-conducting plate 41 can be a VC (Vapor Chamber) heat dissipation plate, so that the heat-conducting plate 41 has the advantage of good heat conduction.

[0078] The heat-conducting plate 41 may also include a copper alloy heat-conducting plate, a stainless steel heat-conducting plate, a graphene heat-conducting plate, etc., and this application embodiment does not limit it.

[0079] The heat-conducting plate 41 can be disposed on one side of the light-emitting assembly 200. For example, the side of the heat-conducting plate 41 in the thickness direction faces the light-emitting assembly 200. The heat sink 42 is disposed on the surface of the heat-conducting plate 41 facing away from the light-emitting assembly 200. Thus, the heat-conducting plate 41 and the heat sink 42 can be disposed in a way that makes full use of the peripheral space of the light-emitting assembly 200.

[0080] Please combine Figure 2 and Figure 3 In some embodiments, the heat dissipation assembly 400 further includes a fan 43. The fan 43 is located on the side of the light-emitting assembly 200 and the heat-conducting plate 41 away from the light-emitting port 11, and the fan 43 has a first air vent 431 facing the light-emitting port 11.

[0081] The first air vent 431 has a first side 432 and a second side 433, which are arranged opposite to each other along the thickness direction of the heat-conducting plate 41.

[0082] One end of the heat-conducting plate 41 is thermally connected to the cooling assembly 300, and the other end of the heat-conducting plate 41 is bent and extended along the direction from the second side 433 toward the first side 432, and extends to the first side 432.

[0083] The fan 43 is used to drive airflow to flow out or in between the first side 432 and the second side 433 of the first air outlet 431, so that the airflow is guided to flow along the heat conduction plate 41 and flows through the heat sink 42.

[0084] So, compared to the end of the heat-conducting plate 41 near the fan 43 being located in the middle of the first side 432 and the second side 433, in this embodiment of the application, the end of the heat-conducting plate 41 away from the cooling assembly 300 is bent to the first side 432, which allows more airflow flowing through the first air outlet 431 to flow along the heat-conducting plate 41 and then through the heat sink 42. This can improve the heat dissipation effect of the heat sink 42, thereby improving the heat dissipation effect of the cooling assembly 300, and ultimately improving the cooling effect of the skin care device.

[0085] Furthermore, since the end of the heat-conducting plate 41 away from the cooling assembly 300 is bent to the first side 432, the fan 43 and the light-emitting assembly 200 can be set at the same level, which simplifies the internal structure design of the skin care device.

[0086] It is understandable that, compared to the heat sink 42 being located on the side of the heat conduction plate 41 facing the light-emitting component 200 and between the light-emitting component 200 and the fan 43, this application can provide more heat sinks 42 that are blown by the flowing air on the side of the heat conduction plate 41 facing away from the light-emitting component 200, which can help provide heat dissipation.

[0087] For example, the heat-conducting plate 41 includes a connecting section 411 and a deflection section 412. The connecting section 411 is located on one side of the light-emitting assembly 200 and is thermally connected to the cooling assembly 300. The deflection section 412 is connected to the end of the connecting section 411 near the first air vent 431. The deflection section 412 bends and extends along the second side 433 toward the first side 432, and the end of the deflection section 412 away from the connecting section 411 forms the other end of the heat-conducting plate 41.

[0088] Furthermore, the air flowing from the fan 43 out of the first air outlet 431 may be guided by the deflection section 412 and flow through the heat sink 42, or the air at the heat sink 42 may be guided by the deflection section 412 and flow into the fan 43 from the first air outlet 431.

[0089] The boundary of the first air vent 431 may include a first edge 434 and a second edge 435. The first edge 434 is located on a first side 432. The second edge 435 is located on a second side 433. The end of the deflection segment 412 away from the connecting segment 411 is flush with the first edge 434, or the end of the deflection segment 412 away from the connecting segment 411 is located on the side of the first edge 434 away from the second edge 435.

[0090] Furthermore, for the area of ​​the first air vent 431 facing the deflection section 412, the airflow flowing out or into the area between the first side 432 and the second side 433 of the first air vent 431 can flow along the heat conduction plate 41 and pass through the heat sink 42.

[0091] It should be noted that the first edge 434 can be the part of the inner wall of the first air vent 431 near the first side 432, and the second edge 435 can be the part of the inner wall of the first air vent 431 near the second side 433.

[0092] It is also understandable that the deflection segment 412 bends and extends along the second side 433 toward the first side 432, so that a larger space can be reserved on the side of the deflection segment 412 away from the light-emitting component 200 along the thickness direction, so as to set a larger heat sink 42, thereby improving the heat dissipation effect on the cooling component 300 by setting a larger heat sink 42.

[0093] For example, the heat sink 42 extends along the light outlet 11 toward the fan 43 so that the air flowing in or out of the first air outlet 431 can flow smoothly across both sides of the heat sink 42 in the thickness direction, thereby improving the heat dissipation effect of the heat sink 42.

[0094] The heat sink 42 may include a near-heat dissipation section 421 and a far-heat dissipation section 422. The near-heat dissipation section 421 is disposed at the connecting section 411, and the far-heat dissipation section 422 is disposed at the deflection section 412. Therefore, on the one hand, compared to the heat sink 42 being disposed only at the connecting section 411 or the deflection section 412, extending the heat sink 42 from the connecting section 411 to the deflection section 412 can make the area of ​​the heat sink 42 larger; on the other hand, the area of ​​the portion of the heat sink 42 disposed at the deflection section 412 (i.e., the far-heat dissipation section 422) can be made larger, thereby improving the heat dissipation effect of the heat sink 42.

[0095] That is to say, in some embodiments, the width of the heat dissipation section 422 can be gradually increased along the direction from the light outlet 11 toward the fan 43.

[0096] For example, the far heat dissipation section 422 has a second free side 4221 that is away from the deflection section 412. The second free side 4221 is inclined in a direction away from the deflection section 412 so that the width of the far heat dissipation section 422 gradually increases in the direction close to the fan 43.

[0097] In some embodiments, the distal heat dissipation section 422 has a connecting side 4222 connected to the deflection section 412. The end of the connecting side 4222 near the fan 43 extends to the first air outlet 431, so that the fan 43 can drive airflow to flow in or out between adjacent heat sinks 42. This can improve the heat dissipation efficiency of the fan 43 on the heat sinks 42.

[0098] In some embodiments, the far heat dissipation section 422 has a connecting side 4222 connected to the deflection section 412, and the connecting side 4222 and the second free side 4221 are inclined in a direction away from each other, so that the width of the far heat dissipation section 422 gradually increases in the direction close to the fan 43.

[0099] In some embodiments, the near heat dissipation section 421 has a first free side 4211 located away from the connecting section 411 and in the direction of the light outlet 11 toward the fan 43. The first free side 4211 is at least partially inclined away from the connecting section 411 so that the width of the near heat dissipation section 421 gradually increases at least partially.

[0100] In some embodiments, the width of the near-heat dissipation section 421 gradually increases at least partially along the direction from the light outlet 11 toward the fan 43. Therefore, compared to a near-heat dissipation section 421 having a uniform width throughout, the embodiments of this application can achieve a larger area for the heat sink 42, thereby improving the heat dissipation effect on the cooling assembly 300.

[0101] In some embodiments, a shrinkage section 12 is provided at one end of the housing 100. The shrinkage section 12 extends from the connection between the near heat dissipation section 421 and the far heat dissipation section 422 to the light emission port 11. The cross-sectional area of ​​the shrinkage section 12 gradually increases along the direction from the light emission port 11 toward the light emission assembly 200.

[0102] This allows the side of the housing 100 with the light outlet 11 to be smaller, making it easier for the user to accurately fit the light outlet 11 onto the user's skin to be treated. Correspondingly, the width of the end of the heat dissipation section 421 near the light outlet 11 is also smaller.

[0103] In some embodiments, the housing 100 is provided with a second air vent 13 and a third air vent 14. The second air vent 13 is located on the side of the third air vent 14 that is close to the light outlet 11. The second air vent 13 faces the heat dissipation section 422, and the third air vent 14 faces the fan 43.

[0104] Taking the second air outlet 13 as the housing air outlet 13a and the third air outlet 14 as the housing air inlet 14a as an example, the fan 43 can drive the airflow outside the housing 100 to flow in from the third air outlet 14, and then blow it through the first air outlet 431 to the deflection section 412 so that it flows along the deflection section 412 and through the heat sink 42. Finally, the airflow flowing through the heat sink 42 flows out from the second air outlet 13 to form an airflow circulation inside and outside the housing 100, thereby dissipating heat from the cooling assembly 300.

[0105] Of course, the second air vent 13 can also be the air inlet 14a of the housing, and the third air vent 14 can be the air outlet 13a of the housing. This application does not limit this.

[0106] Please continue to refer to this. Figure 4 In some embodiments, the skin care device also includes a control circuit board 500, with the deflection section 412 and the fan 43 located on the same side of the control circuit board 500.

[0107] That is to say, the control circuit board 500 can be located on the first side 432 of the first air vent 431. Then, the end of the deflection section 412 away from the connecting section 411 can be located on the side of the first air vent 431 closer to the control circuit board 500.

[0108] Please continue to refer to this. Figure 5 In some embodiments, the fan 43 is mounted on the control circuit board 500. Furthermore, on the one hand, electrical components or wiring can be installed in the area of ​​the control circuit board 500 facing the fan 43 to make full use of the space on the control circuit board 500; on the other hand, a heat dissipation space 436 can also be formed between the fan 43 and the control circuit board 500, so that when the fan 43 is working, it can drive the air flow in the heat dissipation space 436, thereby allowing the fan 43 to be reused for heat dissipation of the control circuit board 500.

[0109] In some embodiments, the angle between the fan 43 and the control circuit board 500 is less than or equal to 10°. That is, the fan 43 and the control circuit board 500 can be approximately parallel.

[0110] Therefore, compared to the fan 43 and the control circuit board 500 being tilted so that one end of the fan 43 abuts against the control circuit board 500, in this embodiment, the area of ​​the control circuit board 500 facing the fan 43 can be reserved to facilitate the installation of electrical components or wiring, and to improve the heat dissipation effect of the control circuit board 500.

[0111] For example, the angle between the fan 43 and the control circuit board 500 is 0°-10°, such as 0°, 1.5°, 2°, 2.7°, 4°, 5°, 6.3°, 7.1°, 8.5°, 9° or 10°. This application embodiment does not limit this.

[0112] In some embodiments, the fan 43 further includes a fourth air outlet 437 and a fifth air outlet 438. The fourth air outlet 437 is located on the side of the fan 43 facing the control circuit board 500, and the fifth air outlet 438 is located on the side of the fan 43 away from the control circuit board 500. Thus, the fan 43 can drive more airflow through the fourth air outlet 437 and the fifth air outlet 438 to improve the heat dissipation effect inside the skin care device.

[0113] For example, the first air outlet 431 is the air outlet of the fan 43. Then, the fourth air outlet 437 and the fifth air outlet 438 can be the air inlets of the fan 43, so that the fan 43 can draw in air from the side closer to the control circuit board 500 and the side farther away from the control circuit board 500, and then flow from the first air outlet 431 to the heat sink 42 for heat dissipation.

[0114] In some embodiments, the fifth air vent 438 is positioned facing the third air vent 14. This allows the fan 43 to drive airflow from outside the housing 100 into the fan 43 sequentially from the third air vent 14 and the fifth air vent 438, and then from the first air vent 431 to the heat sink 42 for heat dissipation.

[0115] It should also be noted that in some embodiments, the fan 43 may only have a fifth air outlet 438 and not a fourth air outlet 437. This application embodiment does not limit this.

[0116] In some embodiments, the skin care device further includes a heat dissipation bracket 600, which is provided with a heat dissipation duct, or the heat dissipation bracket 600 and the housing 100 have a heat dissipation duct, which is connected to a first air outlet 431 for dissipating heat from at least one of the heat dissipation component 400 and the light emission component 200.

[0117] Therefore, when the heat dissipation duct dissipates heat from the light-emitting component 200, it can prevent the light-emitting component 200 from overheating and causing malfunctions or even damage. When the heat dissipation duct dissipates heat from the heat dissipation component 400, it can dissipate heat from the cooling component 300, thereby providing a cooling compress to the skin at the hair removal or skin rejuvenation site, so as to reduce or even eliminate the pain or heat sensation generated during hair removal or skin rejuvenation.

[0118] For example, the heat dissipation duct includes a first heat dissipation duct 61, which is connected to both the first air outlet 431 and the outside of the housing 100. The heat sink 42 is at least partially disposed within the first heat dissipation duct 61, enabling the fan 43 to dissipate heat from the cooling assembly 300. Furthermore, the first heat dissipation duct 61 guides airflow more smoothly through the heat sink 42, thereby improving the heat dissipation effect on the heat sink 42 and ultimately enhancing the heat dissipation effect on the cooling assembly 300.

[0119] For example, the heat dissipation duct includes a second heat dissipation duct 62, which is connected to both the first air outlet 431 and the outside of the housing 100. The light-emitting component 200 is at least partially disposed within the second heat dissipation duct 62, enabling the fan 43 to dissipate heat from the light-emitting component 200. Furthermore, the second heat dissipation duct 62 can guide airflow more smoothly through the light-emitting component 200, thereby improving the heat dissipation effect on the light-emitting component 200.

[0120] It is understood that the heat dissipation duct may have only one of the first heat dissipation duct 61 and the second heat dissipation duct 62, or the heat dissipation duct may have both the first heat dissipation duct 61 and the second heat dissipation duct 62. This application embodiment does not limit this.

[0121] When the heat dissipation duct has a first heat dissipation duct 61 and a second heat dissipation duct 62, the first heat dissipation duct 61 and the second heat dissipation duct 62 can be independent of each other or partially connected. This application embodiment does not limit this.

[0122] In some embodiments, the housing 100 is provided with a housing air inlet 14a and a housing air outlet 13a, with the housing air inlet 14a facing the fan 43. The housing air outlet 13a faces the side of the heat-conducting plate 41 away from the light-emitting assembly 200, and at least a portion of the first heat dissipation air duct 61 is formed between the heat-conducting plate 41 and the housing air outlet 13a, with the heat sink 42 at least partially located between the heat-conducting plate 41 and the housing air outlet 13a.

[0123] Then, the fan 43 can drive the airflow outside the housing 100 to flow in from the housing air inlet 14a, and then blow it through the first air outlet 431 to the deflection section 412 so that it flows along the deflection section 412 and through the heat sink 42. Finally, the airflow flowing through the heat sink 42 flows out from the housing air outlet 13a to form an airflow circulation inside and outside the housing 100, thereby dissipating heat from the cooling assembly 300.

[0124] It is also understandable that since the air inlet 14a of the housing faces directly towards the fan 43, the first air outlet 431 of the fan 43 faces directly towards the deflection section 412 and the heat sink 42, and the air outlet 13a of the housing also faces the heat sink 42, the fan 43 can more smoothly draw in the airflow outside the housing 100 and blow it into the first heat dissipation duct 61, thereby improving the heat dissipation effect on the heat dissipation component 400.

[0125] In some embodiments, the surface of the heat-conducting plate 41 facing away from the light-emitting assembly 200 forms part of the inner wall of the first heat dissipation duct 61. Therefore, by forming part of the inner wall of the first heat dissipation duct 61 with the heat-conducting plate 41, the structure of the heat dissipation bracket 600 can be simplified, thereby facilitating its manufacture.

[0126] Please continue to refer to this. Figure 6 In some embodiments, the first heat dissipation duct 61 is located between the first air outlet 431 and the light outlet 11. The width of the first heat dissipation duct 61 at the end near the light outlet 11 is greater than the width of the end of the first heat dissipation duct 61 away from the light outlet 11, thereby improving the heat dissipation effect of the end of the heat dissipation component 400 near the light outlet 11 (i.e. near the cooling component 300), thereby improving the heat dissipation effect of the cooling component 300.

[0127] Please continue to refer to this. Figure 7 In some embodiments, the end of the first heat dissipation duct 61 near the first air outlet 431 and the end of the second heat dissipation duct 62 near the first air outlet 431 are arranged side by side along the length of the light-emitting component 200, so that both the first heat dissipation duct 61 and the second heat dissipation duct 62 are connected to the first air outlet 431.

[0128] So, taking the first air outlet 431 as the air outlet of the fan 43 as an example, part of the airflow blown out by the fan 43 can flow to the first heat dissipation duct 61 to dissipate heat from the heat dissipation component 400 and the cooling component 300, and the other part can flow to the second heat dissipation duct 62 to dissipate heat from the light-emitting component 200.

[0129] Please refer to this as well. Figure 7 and Figure 8 In some embodiments, the second heat dissipation duct 62 includes an air inlet section 621, a mounting section 622, and an air outlet section 623 connected in sequence. The light-emitting component 200 is at least partially disposed within the mounting section 622. The air inlet section 621 extends from one end of the mounting section 622 to the first air outlet 431 to communicate with the first air outlet 431. The air outlet section 623 extends from the other end of the mounting section 622 toward the fan 43 and communicates with the outside of the housing 100.

[0130] Taking the first air outlet 431 as the air outlet of the fan 43 as an example, the air outlet section 623 can be connected to the second air outlet 13 (i.e., the housing air outlet 13a), thereby connecting with the outside of the housing 100. Furthermore, the fan 43 can drive a portion of the airflow to the first heat dissipation duct 61 to dissipate heat from the heat dissipation component 400 and the cooling component 300, while the other portion of the airflow flows to the second heat dissipation duct 62 to dissipate heat from the light-emitting component 200.

[0131] It should be noted that, as described above, since the end of the heat-conducting plate 41 away from the cooling assembly 300 is bent to the first side 432, the fan 43 and the light-emitting assembly 200 can be set at the same level. Thus, as shown in the figure, the air inlet section 621, the mounting section 622 and the fan 43 can also be set at the same level, which can avoid airflow loss and thus improve the heat dissipation efficiency of the lamp tube 21 while ensuring the heat dissipation efficiency of the cooling assembly 300.

[0132] Please combine Figure 7 , Figure 8 and Figure 9 In some embodiments, the housing 100 is provided with a housing air outlet 13a, and the first heat dissipation air duct 61 and the second heat dissipation air duct 62 are both connected to the housing air outlet 13a to form a Bernoulli structure at the housing air outlet 13a.

[0133] When the fan 43 is running, the pressure at the outlet of the one with the faster flow rate in the first heat dissipation duct 61 and the second heat dissipation duct 62 will be lower, thereby carrying out or drawing out the airflow in the other duct, thus improving the overall heat dissipation effect of the skin treatment equipment.

[0134] For example, in this embodiment, the airflow path within the second heat dissipation duct 62 is more tortuous and longer. Therefore, when the fan 43 is running, the airflow velocity within the first heat dissipation duct 61 is greater than the airflow velocity within the second heat dissipation duct 62. Consequently, at the housing outlet 13a, the airflow exiting the first heat dissipation duct 61 can draw out the airflow within the second heat dissipation duct 62.

[0135] Please continue to refer to this. Figure 10 In some embodiments, a first gas flow space 624 and a second gas flow space 625 are provided between the outer peripheral side of the light-emitting component 200 and the inner wall of the second heat dissipation duct 62, respectively located on opposite sides of the light-emitting component 200. Furthermore, the contact area between the airflow flowing through the first heat dissipation duct 61 and the light-emitting component 200 can be increased by the first gas flow space 624 and the second gas flow space 625, thereby improving the heat dissipation effect of the light-emitting component 200.

[0136] In some embodiments, the inner wall of the second heat dissipation duct 62 is provided with a protrusion 626, which abuts against the outer peripheral side of the light-emitting component 200, thereby creating a first gas flow space 624 and a second gas flow space 625 between the outer peripheral side of the light-emitting component 200 and the inner wall of the second heat dissipation duct 62.

[0137] In some embodiments, a first gas flow space 624 and a second gas flow space 625 are formed between the outer surface of the reflector cup 22 of the light-emitting assembly 200 and the inner wall of the second heat dissipation duct 62.

[0138] The above is a description of the heat dissipation air ducts in the embodiments of this application.

[0139] Please continue to refer to this. Figure 11 In some embodiments, the heat dissipation bracket 600 is provided with a support portion 63, which is used to support the end of the heat-conducting plate 41 away from the first air vent 431. That is, the support portion 63 is used to support the deflection section 412.

[0140] It is understandable that, since the deflection segment 412 is bent and connected to the connecting segment 411, the heat-conducting plate 41 in this embodiment has lower rigidity or strength compared to a straight plate-shaped heat-conducting plate 41. Therefore, when the skin care device is impacted or vibrated, or when the fan 43 drives airflow through the deflection segment 412, the deflection segment 412 is prone to vibration and breakage. Therefore, in this embodiment, by supporting the end of the heat-conducting plate 41 away from the first air outlet 431 (i.e., the deflection segment 412) by the support portion 63, the situation where the deflection segment 412 is easily damaged can be improved.

[0141] For example, the heat dissipation bracket 600 includes a base plate 64 that extends along the fan 43 toward the light outlet 11. One end of the base plate 64 near the light outlet 11 is located on the side of the light-emitting assembly 200 away from the heat-conducting plate 41. The end of the base plate 64 near the fan 43 is bent toward the heat-conducting plate 41 to form a support portion 63.

[0142] It should be noted that the support portion 63 and the deflection segment 412 can abut against each other or have a gap; this embodiment of the application does not limit this.

[0143] In some embodiments, the heat dissipation bracket 600 further includes an isolation portion 65 located between the light-emitting component 200 and the heat-conducting plate 41 to isolate the light-emitting component 200 from the heat-conducting plate 41.

[0144] As mentioned above, taking the heat-conducting plate 41, which includes a vapor chamber, as an example, the vapor chamber can include a copper alloy vapor chamber, a VC (Vapor Chamber) vapor chamber, a stainless steel vapor chamber, a graphene heat sink, etc., and this application embodiment does not limit this. These vapor chambers are usually conductive. Therefore, the isolation part 65 can make the vapor chamber and the light-emitting component 200 closer together, thus making the skin treatment device thinner and lighter, and can also avoid leakage caused by the light-emitting component 200 and the vapor chamber being too close, thereby improving the reliability and safety of the skin treatment device.

[0145] The isolation part 65 can be made of insulating material, such as plastic, rubber, ceramic, etc., and this application embodiment does not limit it.
