[0053] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0055] During the use of a beauty mask, the light source remains continuously lit. Therefore, the temperature of the beauty mask under prolonged lighting conditions significantly impacts the user experience. In related technologies, the light source in a beauty mask can include a light-emitting diode (LED) or an organic light-emitting diode (OLED). Referring to Figure 1, which shows the temperature distribution of an OLED panel provided by related technologies, Figure 1 illustrates the temperature distribution of OLED panel B after 10 minutes of illumination, measured by a thermal imager. The black area A1 represents the hottest area in OLED panel A, due to the presence of heat-generating components such as the driver chip. The white area A2 represents the cooler area in OLED panel A. The thermal imager measured the highest temperature of OLED panel A after 10 minutes of illumination at 49°C and the lowest temperature at 44°C. Since temperatures exceeding 44°C can cause burns to the skin, using an OLED panel as the light source in a beauty mask results in a poor user experience.

[0056] This application provides a beauty mask. Please refer to Figures 2 and 3. Figure 2 is a top view of the beauty mask provided in this application embodiment, and Figure 3 is a cross-sectional view of the beauty mask provided in Figure 2 at point B1-B1. The beauty mask 10 includes: a flexible light-emitting panel 11, a heat-conducting plate 12, and a shell 13.

[0057] In this embodiment, the flexible light-emitting panel 11 can be an OLED panel. Compared to the discrete arrangement of LED beads in an LED panel, the OLED panel, as a surface light source, can improve the uniformity of the light emitted by the flexible light-emitting panel 11, thereby enhancing the beauty effect of the beauty mask 10. Furthermore, the OLED panel has a wider spectrum and is thin and foldable, allowing the beauty mask 10 to adapt to different face shapes, thus increasing the flexibility of the beauty mask 10's design.

[0058] The flexible light-emitting panel 11 includes a panel body 111 and a heat dissipation structure 112 stacked together. The panel body 111 has a light-emitting surface M1 and a back surface M2 disposed opposite to the light-emitting surface M1. The heat dissipation structure 112 is located on the back surface M2 of the panel body 111.

[0059] The panel body 111 can be used to emit light of a specific wavelength towards the side where the light-emitting surface M1 is located, so that the side where the light-emitting surface M1 is located can face the skin. For example, the wavelength of the light emitted by the panel body 111 can be 600 nm-700 nm, the depth of effect of this wavelength of light can be 6 mm, and this wavelength of light can act on the mitochondria of human cells and increase the activity of the mitochondria, thereby allowing the beauty mask 10 to be used for cell repair to achieve a beauty effect. However, the embodiments of this application are not limited to this, and can be specifically set according to beauty needs.

[0060] The heat dissipation structure 112 serves to dissipate heat and provide support for the panel body 111. Specifically, the heat dissipation structure 112 disperses and conducts the heat from the panel body 111 to the heat-conducting plate 12, preventing the light-emitting surface M1 of the panel body 11 from overheating. For example, the heat dissipation structure 112 can be a multi-layered structure to achieve effective heat dissipation. In some examples, the heat dissipation structure 112 can also buffer stress and provide electromagnetic shielding to protect the panel body 111.

[0061] The heat-conducting plate 12 is located on the side of the heat dissipation structure 112 away from the panel body 111, and the heat-conducting plate 12 is in contact with the heat dissipation structure 112. Here, the heat-conducting plate 12 can be a plate-shaped structure made of a material with a high thermal conductivity. In this way, the heat-conducting plate 12 can promptly further disperse and guide the heat conducted by the heat dissipation structure 112 to the outside, thereby reducing the temperature on the side of the light-emitting surface M1. For example, the material of the heat-conducting plate 112 may include metal materials such as copper or aluminum.

[0062] The outer shell 13 is located on the side of the heat-conducting plate 12 away from the flexible light-emitting panel 11, and the outer shell 13 is connected to the edge of the flexible light-emitting panel 11. Here, the outer shell 13 is used to protect the flexible light-emitting panel 11. The connection between the outer shell 13 and the edge of the flexible light-emitting panel 11 can form a cavity, in which the heat-conducting plate 12 and electronic components can be placed, thereby improving the overall structural stability of the beauty mask 10.

[0063] In this application, the heat-conducting plate 12 can be bonded to at least one of the housing 13 and the flexible light-emitting panel 11, thereby improving the structural stability of the heat-conducting plate 12. Alternatively, the heat-conducting plate 12 can be mechanically clamped between the housing 13 and the flexible light-emitting panel 11.

[0064] It should be noted that Figures 2 and 3 only exemplarily illustrate the external structure of one type of beauty mask 10, wherein the flexible light-emitting panel 11, the heat-conducting plate 12, and the outer shell 13 are all curved structures, but this application is not limited to this. The various layered structures in the beauty mask 10 can also be planar structures, or the various layered structures in the beauty mask 10 can also be three-dimensional curved structures that conform to the shape of the face.

[0065] In summary, this application provides a beauty mask in which a heat-conducting plate is disposed between a flexible light-emitting panel and a shell, and the heat-conducting plate is in contact with the heat dissipation structure in the flexible light-emitting panel. In this way, during the long-term lighting process of the flexible light-emitting panel, the heat of the panel body will first be diffused by the heat dissipation structure and transferred to the heat-conducting plate. The heat-conducting plate can then promptly conduct the heat to the outside, thereby preventing the user from being burned and improving the user experience of the beauty mask.

[0066] In this embodiment, the heat-conducting plate is used to promptly direct the heat conducted by the heat dissipation structure to the outside. To improve the overall heat dissipation effect of the beauty mask, the structure of the heat-conducting plate is described below with two exemplary embodiments:

[0067] In a first exemplary embodiment, the heat-conducting plate can be a plate-like structure. Please refer to Figures 4 and 5. Figure 4 is a top view of another beauty mask provided in this application embodiment, and Figure 5 is a cross-sectional view of the beauty mask provided in Figure 4 at point B2-B2 (the beauty mask shown in Figure 5 can be a planar structure, or Figure 5 can also be a cross-sectional view of a curved beauty mask after it has been flattened). The side of the heat-conducting plate 12 facing the outer shell 13 has a plurality of first grooves 121, and the outer shell 13 has a plurality of first through holes K1. At least a portion of the plurality of first grooves 121 communicates with at least a portion of the plurality of first through holes K1.

[0068] The first groove 121 can be used to increase the heat dissipation area of ​​the heat-conducting plate 12. By setting the first groove 121 to be connected with the first through hole K1, air convection can be accelerated. The heat conducted by the heat-conducting plate 12 can be dissipated by heat exchange with the air, thereby improving the heat dissipation efficiency and making the beauty mask cool down quickly.

[0069] It should be noted that in the beauty mask shown in Figure 5, multiple first grooves 121 correspond one-to-one with multiple first through holes K1, and the first grooves 121 are connected to the corresponding first through holes K1. This can improve the heat dissipation effect, but this application is not limited to this. Improving the heat dissipation effect can also be achieved when some of the first grooves 121 are connected to some of the first through holes K1.

[0070] In this application, the shape and structure of the first groove 121 can include various cases. One case, as shown in Figure 5, is that the first groove 121 can be a curved groove, in which case its cross-sectional structure can be semi-circular. Another case, as shown in Figure 6, is a schematic cross-sectional view of the beauty mask provided in Figure 4 at point B2-B2. The first groove 121 can also be a square groove, in which case its cross-sectional structure can be rectangular or trapezoidal. Both of these structures allow the first groove 121 to communicate with the first through hole K1, thereby improving the heat dissipation speed and cooling effect of the beauty mask.

[0071] The width D1 of the first groove 121 in the first direction X1 can be calculated based on the heat dissipation coefficient of the material of the heat-conducting plate 12. For example, the width D1 can range from 2 mm to 3 mm, such as 2.54 mm, but the embodiments of this application are not limited thereto. The thickness of the heat-conducting plate 12 in the direction perpendicular to the panel body 111 can be determined according to the thickness requirements of the beauty mask. For example, the thickness of the heat-conducting plate 12 can range from 3 mm to 10 mm, such as 5 mm. However, the embodiments of this application are not limited thereto.

[0072] Optionally, please refer to Figure 7, which is another cross-sectional view of the beauty mask provided in Figure 4 at point B2-B2. The heat-conducting plate 12 has multiple second grooves 122 on the side facing the heat dissipation structure 112. The second grooves 122 can also increase the heat dissipation area of ​​the heat-conducting plate 12 and exchange heat with the air, thereby improving the heat dissipation effect.

[0073] Both the second groove 122 and the first groove 121 are strip-shaped, and the extending direction of the second groove 122 is parallel to the extending direction of the first groove 121. The strip-shaped second groove 122 and the first groove 121 are easy to manufacture. It should be noted that this application does not strictly require that the extending direction of the second groove 122 be completely parallel to the extending direction of the first groove 121, and they can also be "approximately parallel".

[0074] In this application, the shape and structure of the second groove 122 include several possibilities. One possibility, as shown in Figure 7, is that the second groove 122 can be a curved groove, in which case its cross-sectional structure can be semi-circular. Another possibility, as shown in Figure 8, is a schematic cross-sectional view of the beauty mask provided in Figure 4 at point B2-B2. The second groove 122 can also be a square groove, in which case its cross-sectional structure can be rectangular or trapezoidal. Here, the shape and structure of the first groove 121 can be the same as or different from the shape and structure of the second groove 122; this application does not limit this.

[0075] Optionally, the arrangement of the first groove 121 and the second groove 122 includes the following two cases:

[0076] In the first scenario, please refer to Figure 7. Multiple first grooves 121 and multiple second grooves 122 are alternately distributed along a first direction X1, which intersects with the extending direction of the first grooves 121. In this case, the cross-sectional shape of the heat-conducting plate 12 can be wavy, which facilitates manufacturing.

[0077] In the second scenario, please refer to Figure 8. Multiple first grooves 121 correspond to multiple second grooves 122, and the orthographic projection of the first groove 121 onto the flexible light-emitting panel 11 coincides with the orthographic projection of the second groove 122 onto the flexible light-emitting panel 11. In this case, the cross-sectional shape of the heat-conducting plate 12 may include: a plate-shaped main body portion, and extension portions extending on both sides of the plate-shaped main body portion. The plate-shaped main body portion and the extension portions constitute the multiple first grooves 121 and the multiple second grooves 122.

[0078] Alternatively, please refer to Figure 9, which is another cross-sectional view of the beauty mask provided in Figure 4 at point B2-B2. The heat-conducting plate 12 has multiple heat dissipation cavities 123. The heat dissipation cavities 123 can further increase the heat dissipation area of ​​the heat-conducting plate 12, thereby improving the heat dissipation effect.

[0079] In this application, the heat dissipation cavity 123 can be filled with air, allowing the heat-conducting plate 12 to exchange heat with the air to achieve heat dissipation. The heat dissipation cavity 123 can also be filled with a phase change material or a coolant for heat dissipation. The phase change material can absorb the heat conducted by the heat-conducting plate 12 through a solid-liquid phase change, while the coolant can absorb the heat conducted by the heat-conducting plate 12 through its high specific heat capacity, thereby improving the overall heat dissipation efficiency and cooling rate of the beauty mask.

[0080] In a second exemplary embodiment, the heat-conducting plate can be a porous structure. Referring to Figures 10 and 11, Figure 10 is a partial top view of the heat-conducting plate in a beauty mask according to an embodiment of this application, and Figure 11 is a cross-sectional view of the beauty mask shown in Figure 10 at point B3-B3. The heat-conducting plate 12 has a plurality of mesh holes K2, and the outer shell 13 has a plurality of first through holes K1. At least a portion of the mesh holes K2 communicates with at least a portion of the first through holes K1.

[0081] Multiple mesh holes K2 increase the surface area of ​​the heat-conducting plate 12, providing more heat exchange channels and enabling the heat conducted by the heat-conducting plate 12 to be transferred more effectively from the inside of the material to the outside. By setting the mesh holes K2 to connect with the first through hole K1, air convection can be accelerated, and the heat inside the beauty mask can be quickly dissipated to the outside, thereby improving heat dissipation efficiency and enabling the beauty mask to cool down quickly.

[0082] It should be noted that Figure 11 only shows an exemplary mesh hole K2. The size of the mesh hole K2 is larger than the size of the first through hole K1. In this case, one mesh hole K2 can communicate with multiple first through holes K1, but the embodiments of this application do not limit this. This application can also set multiple mesh holes K2 to multiple first through holes K1 in a one-to-one correspondence, and the mesh hole K2 communicates with the corresponding first through hole K1, or at least two mesh holes K2 can communicate with the same first through hole K1.

[0083] Optionally, the plurality of mesh holes K2 include at least one of a first mesh hole and a second mesh hole:

[0084] (1) Please refer to Figure 12 for the structure of the first mesh hole. Figure 12 is a partial top view of the heat-conducting plate in another beauty mask provided in this application embodiment. A heat-conducting sheet 124 and heat dissipation fins 125 are disposed in the first mesh hole K21. The heat-conducting sheet 124 extends outward from the center of the first mesh hole K21. Multiple parallel heat dissipation fins 125 are distributed between two adjacent heat-conducting sheets 124, and the two ends of the heat dissipation fins 125 are connected to the two adjacent heat-conducting sheets 124. That is, the heat-conducting plate 12 can have a spider web-like structure. The heat-conducting sheet 124 can be used to conduct heat, and the heat dissipation fins 125 are used to exchange heat between the heat inside the heat-conducting plate 12 and the air.

[0085] (2) The structure of the second mesh hole is shown in Figure 10. The second mesh hole K22 is a hollow perforated hole. For example, the second mesh hole K22 can be a regular hexagon, then the heat-conducting plate 12 can be a honeycomb structure. In addition, the shape of the second mesh hole K22 can also include, but is not limited to: circle, ellipse and polygon.

[0086] It should be noted that the first exemplary embodiment and the second exemplary embodiment described above can be combined. That is, the porous heat-conducting plate provided in this application embodiment can also have a first groove and / or a second groove, thereby further improving the heat dissipation effect.

[0087] In this application, the arrangement of the plurality of first through holes in the housing includes the following two cases:

[0088] For the first arrangement, please refer to Figure 4. Multiple first through holes K1 are arranged in rows and columns, and are evenly distributed. In this case, the heat dissipation gain of the first through holes K1 is approximately the same in all areas of the beauty mask.

[0089] For the second arrangement, please refer to Figure 13. Figure 13 is a top view of another beauty mask provided in the embodiment of this application. The beauty mask 10 has: a first heating zone Q1 and a second heating zone Q2. The temperature of the first heating zone Q1 is greater than the temperature of the second heating zone Q2.

[0090] The first heating area Q1 can correspond to the area where the heating device is located in the flexible light-emitting panel, and the second heating area Q2 can correspond to the area outside the heating device in the flexible light-emitting panel. For example, for an OLED light-emitting panel, its heating device may include a driving chip. Figure 13 shows an example where the first heating area Q1 is distributed on the lower side of the beauty mask 10, that is, the driving chip in the flexible light-emitting panel is distributed on the lower side of the beauty mask 10. However, this application is not limited to this, and the driving chip in the flexible light-emitting panel can also be placed on either side.

[0091] The density of the multiple first through holes K1 distributed in the first heating zone Q1 is greater than the density of the multiple first through holes K1 distributed in the second heating zone Q2. That is, the multiple first through holes K1 are distributed in a gradually varying pattern. In this case, the gain in heat dissipation effect of the first through holes K1 in the first heating zone Q1 is greater than the gain in heat dissipation effect of the first through holes K1 in the second heating zone Q2. This improves the heat dissipation speed and effect in the corresponding area of ​​the heat-generating device, thereby enhancing the uniformity of temperature distribution in the beauty mask.

[0092] It should be noted that in the beauty masks shown in Figures 4 and 13, the first through-hole K1 is circular in shape, but the embodiments of this application are not limited to this. For example, the shape of the first through-hole K1 may also include elliptical or square. Furthermore, the embodiments of this application do not limit the size of the first through-hole K1, and it can be designed according to heat dissipation and aesthetic requirements. For example, the diameter of the first through-hole K1 can be 5 mm.

[0093] Optionally, the outer shell 13 may also have multiple clearance holes. For example, Figure 13 shows two eye clearance holes, one nose clearance hole, and one mouth clearance hole. The nose clearance hole may also be connected to the mouth clearance hole. The eye clearance holes prevent the beauty mask from obstructing the user's vision, allowing the user to perform other activities while using the mask, thus increasing the versatility of the beauty mask's use cases. The nose and mouth clearance holes can increase breathability, reducing the user's feeling of stuffiness during use, thereby improving the user experience.

[0094] In this embodiment, the heat dissipation structure is used to disperse the heat generated by the face mask and conduct it to the heat-conducting plate. To improve the overall heat dissipation effect of the beauty mask, the structure of the heat dissipation structure is described below with reference to an exemplary embodiment:

[0095] Please refer to Figure 14, which is a cross-sectional structural diagram of another beauty mask provided in an embodiment of this application. The heat dissipation structure 112 includes: a stacked metal support layer 112a and a heat dissipation layer 112b.

[0096] Specifically, in the direction parallel to the panel body 111, the thermal conductivity of the heat dissipation layer 112b is greater than that of the metal support layer 112a. In the direction perpendicular to the panel body 111, the thermal conductivity of the metal support layer 112a is greater than that of the heat dissipation layer 112b. Based on the thermal conductivity of the metal support layer 112a and the heat dissipation layer 112b, the heat dissipation layer 112b can be used to disperse the heat of the panel body 111, and the metal support layer 112a can be used to guide the heat of the panel body 111 to the heat-conducting plate 12.

[0097] Please refer to Table 1, which compares the thermal conductivity of some materials in different directions. The thermal conductivity in the XY plane can be the thermal conductivity of the metal support layer 112a or the heat spreader layer 112b in the direction parallel to the panel body 111, and the thermal conductivity in the Z-axis can be the thermal conductivity of the metal support layer 112a or the heat spreader layer 112b in the direction perpendicular to the panel body 111. The unit of thermal conductivity is watts per meter Kelvin (W / (m·K)). Table 1 shows that stainless steel and aluminum plates have high thermal conductivity in the Z-axis, meaning they have high thermal conductivity and are suitable for the metal support layer 112a. Graphite sheets and metal matrix composites have high thermal conductivity in the XY plane, meaning they have high heat spreader properties and are suitable for the heat spreader layer 112b. Metal matrix composites combine carbon-based materials and metal materials, giving them both high thermal conductivity and high heat spreader properties.

[0099] Optionally, please refer to Table 2, which is a reference table of the thermal conductivity and applicable thickness range of the materials that can be used for the metal support layer and the heat spreader layer. The materials of the metal support layer 112a may include, but are not limited to, metal materials such as aluminum, copper, titanium and stainless steel, and the materials of the heat spreader layer 112b may include, but are not limited to, graphite, graphene, vacuum chamber (VC) heat spreader plates, nanomaterials and metal matrix composites.

[0100] Table 2

[0101] A vacuum chamber vapor chamber is a structure that utilizes phase change for heat dissipation. It can include a substrate, capillary structures, a vapor chamber, and a working fluid. When heat is conducted to the evaporation zone of the vapor chamber, the working fluid evaporates, generating steam. The steam rapidly diffuses within the vapor chamber, transferring heat to the condensation zone. In the condensation zone, the steam condenses into a liquid, releasing heat. The condensed liquid then flows back to the evaporation zone through the capillary structures, where it is heated and evaporates again. This cycle repeats continuously, achieving rapid heat transfer and uniform heating.

[0102] In this embodiment, since the metal support layer 112a and the heat dissipation layer 112b have different thermal conductivity characteristics, different heat dissipation effects can be achieved by setting the positions of the metal support layer 112a and the heat dissipation layer 112b relative to the panel body 111. The positions of the metal support layer 112a and the heat dissipation layer 112b include the following two cases:

[0103] For the first scenario, please refer to Figure 14. The heat dissipation layer 112b is located between the panel body 111 and the metal support layer 112a. In this way, the heat dissipation layer 112b is closer to the panel body 111, which allows the heat of the panel body 111 to be quickly diffused and then transferred to the metal support layer 112a. That is, the first scenario is a scheme of heat dissipation first and then heat conduction.

[0104] For the second scenario, please refer to Figure 15, which is a cross-sectional structural diagram of another beauty mask provided in this application embodiment. The metal support layer 112a is located between the panel body 111 and the heat dissipation layer 112b. In this way, the metal support layer 112a is closer to the panel body 111, which allows the heat from the panel body 111 to be transferred to the metal support layer 112a and then diffused. That is, the second scenario is a scheme of conducting heat first and then dissipating heat.

[0105] This application embodiment also conducted temperature rise tests on the flexible light-emitting panel 11 under the above two conditions and compared them with related technologies. The temperature rise tests were all conducted two hours after the flexible light-emitting panel 11 was lit. Please refer to Figures 16 and 17. Figure 16 is a comparative schematic diagram of the overall temperature difference of the flexible light-emitting panel provided by the embodiments of this application and related technologies, and Figure 17 is a comparative schematic diagram of the maximum temperature rise of the flexible light-emitting panel provided by the embodiments of this application and related technologies. Specifically, Embodiment 1 is the scheme of first homogenizing the heat and then conducting the heat, as shown in Figure 14, and Embodiment 2 is the scheme of first conducting the heat and then homogenizing the heat, as shown in Figure 15. The overall temperature difference refers to the difference between the highest and lowest temperatures of the flexible light-emitting panel, and the maximum temperature rise refers to the maximum difference between the temperature of the flexible light-emitting panel and the ambient temperature.

[0106] As shown in Figure 16, the overall temperature difference measured for the flexible light-emitting panel in Example 1 is 5.4℃, the overall temperature difference measured for the flexible light-emitting panel in Example 2 is 7.05℃, and the overall temperature difference measured for the flexible light-emitting panel provided by related technologies is 8.8℃. Among them, the overall temperature difference measured for the flexible light-emitting panel in Example 1 is the smallest, that is, the scheme of first homogenizing the heat and then conducting the heat can achieve a smaller overall temperature difference and better temperature uniformity.

[0107] As shown in Figure 17, the maximum temperature rise measured in the flexible light-emitting panel of Example 1 is 20.7℃, the maximum temperature rise measured in the flexible light-emitting panel of Example 2 is 22.6℃, and the maximum temperature rise measured in the flexible light-emitting panel provided by the related technology is 23.5℃. Among them, the maximum temperature rise measured in the flexible light-emitting panel of Example 1 is the smallest, which is 1.9℃ lower than that of Example 2 and 2.8℃ lower than that of the related technology. That is, the scheme of heat equalization before heat conduction can achieve a smaller maximum temperature rise and a better heat dissipation effect.

[0108] Based on the temperature rise test results in Figures 16 and 17, it can be seen that the overall temperature difference and maximum temperature rise of the flexible light-emitting panel provided in this application embodiment are both small. Furthermore, when the metal support layer 112a is located between the panel body 111 and the heat dissipation layer 112b, that is, the scheme of heat dissipation first and then heat conduction can achieve better heat dissipation effect and temperature uniformity.

[0109] Furthermore, for areas with concentrated heat sources (such as point heat sources), a method of first equalizing the heat and then conducting the heat can be adopted, that is, rapidly reducing the local temperature of the heat source first. For areas with a large heat source area (such as area heat sources), a method of first conducting the heat and then equalizing the heat can be adopted, that is, increasing the heat conduction area first to transfer as much heat as possible. Since the OLED panel is driven by a driver chip, and the driver chip is the main heat source, the method of first equalizing the heat and then conducting the heat can be used in the beauty mask provided in this application embodiment.

[0110] Optionally, the heat dissipation structure 112 may further include a first adhesive layer 112c, which may be located between the metal support layer 112a and the heat spreader layer 112b, and is bonded to both the metal support layer 112a and the heat spreader layer 112b, thereby fixing the metal support layer 112a and the heat spreader layer 112b. In the embodiment shown in FIG. 14, the first adhesive layer 112c may also be located between the heat spreader layer 112b and the panel body 111, and is bonded to both the heat spreader layer 112b and the panel body 11, thereby fixing the heat dissipation structure 112 to the back surface M2 of the panel body 111. In the embodiment shown in FIG15, the first adhesive layer 112c may also be located between the metal support layer 112a and the panel body 111, and the first adhesive layer 112c is bonded to the metal support layer 112a and the panel body 11 respectively. In this case, the first adhesive layer 112c can fix the heat dissipation structure 112 to the back surface M2 of the panel body 111.

[0111] For example, the first adhesive layer 112c can be a thermally conductive adhesive, which can improve the thermal conductivity between the panel body 111 and the heat dissipation structure 112, and improve the thermal conductivity between the metal support layer 112a and the heat dissipation layer 112b, thereby improving the heat dissipation rate.

[0112] Optionally, please refer to Figure 18, which is a cross-sectional structural schematic diagram of another beauty mask provided in an embodiment of this application. The beauty mask 10 further includes a protective layer 14, which covers the light-emitting surface M1 of the panel body 111. The protective layer 14 can be used to protect the light-emitting surface M1 of the flexible light-emitting panel 11. The material of the protective layer 14 can be light-transmitting to avoid affecting the light emission brightness of the flexible light-emitting panel 11, thereby preventing the beauty effect of the beauty mask. For example, the material of the protective layer 14 can include, but is not limited to, light-transmitting materials such as polyethylene terephthalate (PET), colorless polyimide (CPI), ultra-thin glass (UTG), and silicone.

[0113] The beauty mask 10 may further include a second adhesive layer 15, which is located between the protective layer 14 and the panel body 111, and is bonded to both the protective layer 14 and the panel body 111. For example, the second adhesive layer 15 may be an optically transparent adhesive, thereby avoiding affecting the light emission brightness of the flexible light-emitting panel 11, and thus preventing the beauty mask from achieving its desired cosmetic effect.

[0114] The flexible light-emitting panel 11 may further include a driving chip 113, which is located on the panel body 111. One end of the panel body 111 on which the driving chip 113 is located can be bent to the side of the heat dissipation structure 112 away from the panel body 111. This allows the driving chip 113, which generates more heat, to be closer to the outside, facilitating heat exchange with the air and thus improving heat dissipation. In some embodiments, the driving chip 113 is located on a flexible circuit board, one end of which is connected to the panel body 111, and the other end of which is bent to the side of the heat dissipation structure 112 away from the panel body 111. This also allows the driving chip 113, which generates more heat, to be closer to the outside, thereby improving heat dissipation.

[0115] In this application embodiment, the form of the beauty mask can include various situations:

[0116] In one scenario, the beauty mask can be of a fixed shape. To better fit the user's facial features, the beauty mask can be a three-dimensional curved structure that conforms to the face shape. This minimizes the difference in distance between the beauty mask and the face across different areas, thereby improving the uniformity of light intensity on the face, enhancing the beauty effect, and making it easier to wear. Since the human face has certain contours, especially at the bridge of the nose and forehead, the beauty mask needs a greater degree of curvature. Therefore, in the beauty mask provided in this application embodiment, the number of flexible light-emitting panels can be one or multiple flexible light-emitting panels spliced ​​together; this application embodiment does not impose any limitation on this.

[0117] In another scenario, the beauty mask can be a non-fixed, flexible form, meaning it can change shape. This improves its applicability to various face shapes, thereby enhancing the user experience. Two exemplary embodiments are described below:

[0118] In the first embodiment, the beauty mask can change shape once. Please refer to Figures 18 and 19. Figure 19 is a schematic diagram of the deformation process of a beauty mask provided in this embodiment. The protective layer 14 is a flexible protective layer, and the heat dissipation structure 112 is a plastic structure. For example, the protective layer 14 can be a thermoplastic elastomer, which is plastic at high temperatures and elastic at low temperatures. The material of the metal support layer 112a in the heat dissipation structure 112 can include aluminum foil or copper foil, and the thickness of the metal support layer 112a can be 13 micrometers to 150 micrometers, thereby allowing the metal support layer 112a to be bent. In this way, the flexible light-emitting panel 11 can undergo one deformation.

[0119] The flexible light-emitting panel 11 is configured to deform in the direction toward the outer shell 13 when the user first wears the beauty mask 10. Because the flexible light-emitting panel 11 can deform in one step, this improves the fit between the flexible light-emitting panel 11 and the user's face shape.

[0120] It should be noted that the initial form of the flexible light-emitting panel 11 shown in Figure 19 is a planar structure, but the embodiments of this application are not limited to this. The initial form of the flexible light-emitting panel 11 can also be a curved structure, which can reduce the difficulty of deformation of the flexible light-emitting panel 11.

[0121] Optionally, the protective layer 14 can be made of a superplastic material, which gives the protective layer 14 good extensibility and fluidity. When another user uses the beauty mask 10, similar to the principle of clay, the protective layer 14 can undergo slight deformation to make the beauty mask 10 fit the face of the other user, thereby improving the adaptability of the flexible light-emitting panel 11 to the face shape of the other user.

[0122] In the second embodiment, the beauty mask can change shape multiple times. Please refer to Figures 18 and 20. Figure 20 is a schematic diagram of the deformation process of another beauty mask provided in this application embodiment. The protective layer 14 is a flexible protective layer, and the heat dissipation structure 112 is an elastic structure. For example, the material of the metal support layer 112a in the heat dissipation structure 112 can include, but is not limited to, stainless steel, aluminum, copper, carbon fiber, composite graphite, etc., and the deformation of the flexible light-emitting panel 11 is controlled within the elastic deformation range. In this way, the flexible light-emitting panel 11 can elastically return to its initial shape after deformation.

[0123] The flexible light-emitting panel 11 is configured to deform in the direction toward the outer shell 13 when the user wears the beauty mask 10, and return to its initial shape after the user removes the beauty mask 10. Because the flexible light-emitting panel 11 can return to its initial shape after deformation, its shape can match the face shape of different users, thereby improving the compatibility of the flexible light-emitting panel 11 with different face shapes and meeting the usage needs of different users.

[0124] It should be noted that the initial form of the flexible light-emitting panel 11 shown in Figure 20 is a planar structure, but the embodiments of this application are not limited to this. The initial form of the flexible light-emitting panel 11 can also be a curved structure, which can reduce the difficulty of deformation of the flexible light-emitting panel 11 and ensure that the deformation of the flexible light-emitting panel 11 can be controlled within the elastic deformation range.

[0125] In summary, this application provides a beauty mask in which a heat-conducting plate is disposed between a flexible light-emitting panel and a shell, and the heat-conducting plate is in contact with the heat dissipation structure in the flexible light-emitting panel. In this way, during the long-term lighting process of the flexible light-emitting panel, the heat of the panel body will first be diffused by the heat dissipation structure and transferred to the heat-conducting plate. The heat-conducting plate can then promptly conduct the heat to the outside, thereby preventing the user from being burned and improving the user experience of the beauty mask.

[0126] On the other hand, embodiments of this application also provide a beauty device, which includes: a wearing part and a beauty mask connected to the wearing part. For example, the wearing part may include: straps, etc.

[0127] Since the beauty device includes the beauty mask provided in any of the above embodiments, the beauty device can also have a similar effect, that is, it can enhance the user experience of the beauty device.

[0128] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0129] In this application, the term "at least one of A and B" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, "at least one of A and B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0130] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.
