[0052] The specific embodiments of the present application have been shown in the above drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0054] In the use process of the beauty mask, the light source of the beauty mask will be continuously in the lighting state, and therefore the temperature of the beauty mask in the case of long-term lighting of the light source has a greater impact on the user experience. In the related art, the light source in the beauty mask can include a light-emitting diode (LED) or an organic light-emitting diode (OLED). Please refer to Figure 1 , Figure 1 is a temperature distribution diagram of an organic light-emitting diode panel provided by the related art, Figure 1 is a temperature distribution diagram of the organic light-emitting diode panel B tested by a thermal imager after lighting for 10 minutes, the black area A1 is the hottest heating area in the organic light-emitting diode panel A, which is due to the distribution of heating devices such as driving chips in the heating area, and the white area A2 is a lower temperature area in the organic light-emitting diode panel A. Among them, the highest temperature of the organic light-emitting diode panel A measured by the thermal imager after lighting for 10 minutes is 49℃, and the lowest temperature is 44℃. Since more than 44℃ can cause burns to the skin, when the organic light-emitting diode panel provided by the related art is applied as the light source of the beauty mask, the user experience will be poor.

[0055] An embodiment of the present application provides a beauty mask, please refer to Figure 2 and Figure 3 , Figure 2 is a top view structural schematic diagram of a beauty mask provided by an embodiment of the present application, Figure 3 is Figure 2 a cross-sectional schematic diagram of the beauty mask provided by the present application at B1-B1. The beauty mask 10 includes a flexible light-emitting panel 11, a heat-conducting plate 12 and an outer shell 13.

[0056] In the embodiment of the present application, the flexible light-emitting panel 11 can be an OLED panel. Compared with the arrangement of discrete lamp 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 improving the beautifying effect of the beautifying mask 10. Moreover, the OLED panel has a wider spectrum and has the characteristics of being light and thin and foldable, so that the beautifying mask 10 can adapt to different face shape requirements, thereby improving the flexibility of the appearance design of the beautifying mask 10.

[0057] The flexible light-emitting panel 11 includes a panel body 111 and a heat dissipation structure 112 which are stacked. The panel body 111 has a light-emitting surface M1 and a back surface M2 opposite to the light-emitting surface M1. The heat dissipation structure 112 is located on the back surface M2 of the panel body 111.

[0058] The panel body 111 can be used to emit light of a specific wavelength band to the side where the light-emitting surface M1 is located, and the side where the light-emitting surface M1 is located can face the skin. For example, the wavelength band of the light emitted by the panel body 111 can be 600-700 nm, the depth of action of the light of this wavelength band can be 6 mm, and the light of this wavelength band can act on the mitochondria of human cells and increase the activity of the mitochondria, so that the beautifying mask 10 can be used for cell repair to achieve a beautifying effect. However, the embodiment of the present application is not limited thereto, and the beautifying requirement can be set according to the beautifying requirement.

[0059] The heat dissipation structure 112 can be used to dissipate heat and support the panel body 111. Specifically, the heat dissipation structure 112 can disperse and conduct the heat of the panel body 111 to the heat conduction plate 12 to prevent the temperature of the light-emitting surface M1 of the panel body 11 from being too high. For example, the heat dissipation structure 112 can be a multi-layer structure to achieve effective heat dissipation effect. In some examples, the heat dissipation structure 112 can also play a role in buffering stress and electromagnetic shielding to achieve a protection effect on the panel body 111.

[0060] The heat conduction plate 12 is located on the side of the heat dissipation structure 112 away from the panel body 111, and the heat conduction plate 12 is in contact with the heat dissipation structure 112. Here, the heat conduction plate 12 can be a plate-shaped structure made of a material with a high heat conductivity, so that the heat conduction plate 12 can further disperse and conduct 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 conduction plate 112 can include metal materials such as copper or aluminum.

[0061] The shell 13 is located on the side of the heat-conducting plate 12 away from the flexible light-emitting panel 11, and the shell 13 is connected with the edge of the flexible light-emitting panel 11. Here, the shell 13 is used to protect the flexible light-emitting panel 11, and the connection of the shell 13 with the edge of the flexible light-emitting panel 11 can form a cavity, and the heat-conducting plate 12 and the electronic elements can be arranged in the cavity, so as to improve the overall structural stability of the beauty mask 10.

[0062] In the present application, the heat-conducting plate 12 can be bonded with at least one of the shell 13 and the flexible light-emitting panel 11, so as to improve the structural stability of the heat-conducting plate 12. In addition, the heat-conducting plate 12 can also be clamped between the shell 13 and the flexible light-emitting panel 11 by mechanical force.

[0063] It should be noted that, Figure 2 and Figure 3 Only an external structure of a beauty mask 10 is exemplarily shown, in which the flexible light-emitting panel 11, the heat-conducting plate 12 and the shell 13 are all curved structures, but the present application is not limited thereto. The various laminated structures in the beauty mask 10 can also be planar structures, or the various laminated structures in the beauty mask 10 can also be three-dimensional curved structures conforming to the face shape.

[0064] In summary, the embodiment of the present application provides a beauty mask, in which a heat-conducting plate is arranged between the flexible light-emitting panel and the shell, and the heat-conducting plate is in contact with the heat-dissipating structure in the flexible light-emitting panel. In this way, during the long-term lighting of the flexible light-emitting panel, the heat of the panel body is first diffused by the heat-dissipating structure and transmitted to the heat-conducting plate, and then the heat-conducting plate can timely guide the heat to the outside, so as to avoid the user from being scalded, and thus the use experience of the beauty mask can be improved.

[0065] In the embodiment of the present application, the heat-conducting plate is used to timely guide the heat conducted by the heat-dissipating structure to the outside. In order to improve the overall heat-dissipating effect of the beauty mask, the structure of the heat-conducting plate will be described in two exemplary embodiments as follows:

[0066] In the first exemplary embodiment, the heat-conducting plate can be a plate structure, please refer to Figure 4 and Figure 5 , Figure 4 is a top view structural schematic diagram of another beauty mask provided by the embodiment of the present application, Figure 5 is Figure 4 a sectional view schematic diagram of the beauty mask provided by the embodiment of the present application at B2-B2 Figure 5 The beauty mask shown can be a planar structure, or Figure 5(This can also be a cross-sectional view of a beauty mask with a curved structure 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.

[0067] 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.

[0068] It should be noted that, Figure 5 In the illustrated beauty mask, 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, which 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.

[0069] In this application, the shape and structure of the first groove 121 can include various cases. One case is as follows: Figure 5 As shown, the first groove 121 can be a curved groove, so the cross-sectional structure of the first groove 121 can be semi-circular. Another case is as follows... Figure 6 As shown, Figure 6 yes Figure 4 Another cross-sectional view of the provided beauty mask at B2-B2 is shown. The first groove 121 can also be a square groove, in which case the cross-sectional structure of the first groove 121 can be rectangular or trapezoidal. Both of these structures of the first groove 121 can be connected to the first through hole K1 to improve the heat dissipation speed and cooling effect of the beauty mask.

[0070] 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.

[0071] Alternatively, please refer to Figure 7 , Figure 7 yes Figure 4Another cross-sectional view of the provided beauty mask at 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.

[0072] 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".

[0073] In this application, the shape and structure of the second groove 122 include various cases. One case is as follows: Figure 7 As shown, the second groove 122 can be a curved groove, so the cross-sectional structure of the second groove 122 can be semi-circular. Another case is as follows... Figure 8 As shown, Figure 8 yes Figure 4 Another cross-sectional view of the provided beauty mask at B2-B2. The second groove 122 can also be a square groove, and the cross-sectional structure of the second groove 122 can be rectangular or trapezoidal. Here, the shape and structure of the first groove 121 and the second groove 122 can be the same or different, and this application embodiment does not limit this.

[0074] Optionally, the arrangement of the first groove 121 and the second groove 122 includes the following two cases:

[0075] Please refer to the first scenario. Figure 7 Multiple first grooves 121 and multiple second grooves 122 are alternately distributed in 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.

[0076] Please refer to the second scenario. Figure 8 The plurality of first grooves 121 correspond to the plurality of second grooves 122, and the orthographic projection of the first groove 121 on the flexible light-emitting panel 11 coincides with the orthographic projection of the second groove 122 on 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 constituting the plurality of first grooves 121 and the plurality of second grooves 122.

[0077] Alternatively, please refer to Figure 9 , Figure 9 yes Figure 4Another cross-sectional view of the cosmetic mask is provided at B2-B2. The heat-conducting plate 12 has a plurality of 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.

[0078] In the present application, the heat dissipation cavities 123 can be filled with air, and the heat-conducting plate 12 can exchange heat with the air to achieve heat dissipation. The heat dissipation cavities 123 can also be filled with phase change materials or cooling liquid to achieve heat dissipation. The phase change materials can absorb the heat conducted by the heat-conducting plate 12 through solid-liquid phase change, and the cooling liquid can absorb the heat conducted by the heat-conducting plate 12 through the high specific heat capacity of the liquid, thereby improving the overall heat dissipation efficiency and cooling rate of the cosmetic mask.

[0079] In a second exemplary embodiment, the heat-conducting plate can have a porous structure, as shown in Figure 10 and Figure 11 , Figure 10 is a partial top view of a heat-conducting plate in a cosmetic mask according to an embodiment of the present application, Figure 11 is Figure 10 A cross-sectional view of the cosmetic mask is shown at B3-B3. The heat-conducting plate 12 has a plurality of grid holes K2, and the outer shell 13 has a plurality of first through holes K1. At least some of the plurality of grid holes K2 are in communication with at least some of the plurality of first through holes K1.

[0080] The plurality of grid holes K2 can increase the surface area of the heat-conducting plate 12, providing more heat exchange channels, so that the heat conducted by the heat-conducting plate 12 can be more effectively conducted from the inside of the material to the outside. By setting the grid holes K2 in communication with the first through holes K1, the air convection can be accelerated, and the heat inside the cosmetic mask can be quickly dissipated to the outside, thereby improving the heat dissipation efficiency and enabling the cosmetic mask to cool down quickly.

[0081] It should be noted that Figure 11 only one exemplary grid hole K2 is shown, which has a size larger than that of the first through hole K1, so that one grid hole K2 can be in communication with a plurality of first through holes K1, but the present application is not limited thereto. The present application can also set a one-to-one correspondence between the plurality of grid holes K2 and the plurality of first through holes K1, and the grid holes K2 are in communication with the corresponding first through holes K1, or at least two grid holes K2 can be in communication with the same first through hole K1.

[0082] Optionally, the plurality of grid holes K2 includes at least one of a first grid hole and a second grid hole:

[0083] (1) The structure of the first grid hole can refer to Figure 12 , Figure 12is another partial top view structure schematic diagram of the heat conduction plate in the beauty mask provided by the embodiment of the present application. The first grid hole K21 is provided with heat conduction sheets 124 and heat dissipation fins 125. The heat conduction sheets 124 extend outward from the center of the first grid hole K21, and a plurality of heat dissipation fins 125 arranged in parallel are distributed between two adjacent heat conduction sheets 124, and the two ends of the heat dissipation fins 125 are connected with the two adjacent heat conduction sheets 124. That is, the heat conduction plate 12 can be a spider web structure. The heat conduction sheets 124 can be used for heat conduction, and the heat dissipation fins 125 are used for heat exchange between the heat conduction plate 12 inside and the air.

[0084] (2) The structure of the second grid hole please refer to Figure 10 , the second grid hole K22 is a hollow hole. For example, the second grid hole K22 can be a regular hexagon, and the heat conduction plate 12 can be a honeycomb structure. In addition, the shape of the second grid hole K22 can include but is not limited to: circular, oval and polygonal.

[0085] It should be noted that the first exemplary embodiment and the second exemplary embodiment described above can be combined, that is, the heat conduction plate with a porous structure provided by the embodiment of the present application can also have a first groove and / or a second groove, so as to further improve the heat dissipation effect.

[0086] In the present application, the arrangement of the plurality of first through holes in the shell includes the following two cases:

[0087] The first arrangement please refer to Figure 4 , the plurality of first through holes K1 are arranged in rows and columns, and the plurality of first through holes K1 are uniformly distributed. In this case, the gain of the first through hole K1 on the heat dissipation effect in each area of the beauty mask is approximately the same.

[0088] The second arrangement please refer to Figure 13 , Figure 13 is another top view structure schematic diagram of the beauty mask provided by the embodiment of the present application. The beauty mask 10 has: a first heating area Q1 and a second heating area Q2, and the temperature of the first heating area Q1 is greater than that of the second heating area Q2.

[0089] The first heating area Q1 can correspond to the area where the heating device in the flexible light-emitting panel is located, and the second heating area Q2 can correspond to the area other than the heating device in the flexible light-emitting panel. For example, for an OLED light-emitting panel, the heating device can include a driving chip. Figure 13 For example, 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, but the present application is not limited thereto, and the present application can also set the driving chip in the flexible light-emitting panel on any side.

[0090] The density of the plurality of first through holes K1 distributed in the first heat generation area Q1 is greater than the density of the plurality of first through holes K1 distributed in the second heat generation area Q2. That is, the plurality of first through holes K1 are distributed in a gradient manner. In this case, the gain of the first through holes K1 in the first heat generation area Q1 on the heat dissipation effect is greater than the gain of the first through holes K1 in the second heat generation area Q2 on the heat dissipation effect, so as to improve the heat dissipation speed and heat dissipation effect of the area corresponding to the heat generating device, and further improve the uniformity of the temperature distribution of the beauty mask.

[0091] It should be noted that, Figure 4 and Figure 13 The shape of the first through hole K1 in the beauty mask shown is a circle, but the embodiment of the present application is not limited thereto, for example, the shape of the first through hole K1 can also include an oval or a square. Moreover, the embodiment of the present application does not limit the size of the first through hole K1, which can be designed according to the heat dissipation needs and aesthetic needs. For example, the aperture of the first through hole K1 can be 5 millimeters.

[0092] Optionally, the shell 13 can also have a plurality of avoiding holes. For example, Figure 13 Two eye avoiding holes, one nose avoiding hole and one mouth avoiding hole are shown, and the nose avoiding hole can also be communicated with the mouth avoiding hole. The eye avoiding hole can avoid the beauty mask from blocking the user's line of sight, so that the user can perform other activities during the use of the beauty mask, thereby increasing the universality of the use scene of the beauty mask. The nose avoiding hole and the mouth avoiding hole can be used to increase the air permeability and reduce the stuffy feeling of the user during use, thereby improving the user experience.

[0093] In the embodiment of the present application, the heat dissipation structure is used to disperse the heat of the face version and conduct to the heat conduction plate. In order to improve the overall heat dissipation effect of the beauty mask, the structure of the heat dissipation structure is described below with an exemplary embodiment:

[0094] Please refer to Figure 14 , Figure 14 is another cross-sectional structure schematic diagram of a beauty mask provided by the embodiment of the present application. The heat dissipation structure 112 includes a metal support layer 112a and a uniform heating layer 112b which are stacked.

[0095] In a direction parallel to the panel body 111, the thermal conductivity of the heat-diffusing layer 112b is greater than that of the metal support layer 112a. In a direction perpendicular to the panel body 111, the thermal conductivity of the metal support layer 112a is greater than that of the heat-diffusing layer 112b. Based on the thermal conductivities of the metal support layer 112a and the heat-diffusing layer 112b, the heat-diffusing layer 112b can be used to diffuse 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.

[0096] Referring to Table 1, Table 1 is a comparison table of thermal conductivities of some materials in different directions. In Table 1, the thermal conductivity in the X-Y plane can be the thermal conductivity of the metal support layer 112a or the heat-diffusing layer 112b in a 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-diffusing layer 112b in a direction perpendicular to the panel body 111. The unit of the thermal conductivity is watt per meter kelvin (W / (m·K)). As shown in Table 1, the thermal conductivities of stainless steel and aluminum plate in the Z-axis are relatively high, i.e., the stainless steel and the aluminum plate have relatively high thermal conductivity, and can be suitable for the metal support layer 112a. The thermal conductivities of graphite sheet and metal matrix composite in the X-Y plane are relatively high, i.e., the graphite sheet and the metal matrix composite have relatively high heat-diffusing property, and can be suitable for the heat-diffusing layer 112b. The metal matrix composite is a composite of carbon-based material and metal material, so that the metal matrix composite has relatively high thermal conductivity and heat-diffusing property.

[0102] The vacuum cavity heat plate is a structure for heat dissipation by phase change. The vacuum cavity heat plate can include a substrate, a capillary structure, a vapor cavity, and a working fluid. When heat is conducted to the evaporation area of the vacuum cavity heat plate, the working fluid is heated and evaporated to generate steam. The steam rapidly spreads in the vapor cavity to transfer heat to the condensation area. In the condensation area, the steam condenses into liquid to release heat. The condensed liquid returns to the evaporation area through the capillary structure, is heated and evaporated again, and the cycle is repeated, so that rapid heat transfer and heat equalization can be achieved.

[0103] In the embodiment of the present application, different heat dissipation effects can be achieved by setting the positions of the metal support layer 112a and the heat equalization layer 112b relative to the panel body 111 due to the different heat conduction characteristics of the metal support layer 112a and the heat equalization layer 112b. The setting positions of the metal support layer 112a and the heat equalization layer 112b include the following two cases:

[0104] The first case is shown in Figure 14 , in which the heat equalization layer 112b is located between the panel body 111 and the metal support layer 112a. In this way, the heat equalization layer 112b is closer to the panel body 111, which can make the heat of the panel body 111 rapidly spread and then be transferred to the metal support layer 112a. That is, the first case is a scheme of heat equalization first and then heat conduction.

[0105] The second case is shown in Figure 15 , Figure 15 is another cross-sectional structure diagram of a beauty mask provided in the embodiment of the present application. The metal support layer 112a is located between the panel body 111 and the heat equalization layer 112b. In this way, the metal support layer 112a is closer to the panel body 111, which can make the heat of the panel body 111 be transferred to the metal support layer 112a and then be spread. That is, the second case is a scheme of heat conduction first and then heat equalization.

[0106] The temperature rise test of the flexible light-emitting panel 11 in the above two cases is also performed in the embodiment of the present application, and the temperature rise test is compared with the related art. The temperature rise test is performed after the flexible light-emitting panel 11 is lit for two hours. Please refer to Figure 16 and Figure 17 , Figure 16 is a comparison diagram of the overall temperature difference of the flexible light-emitting panel provided in the embodiment of the present application and the related art, Figure 17 is a comparison diagram of the maximum temperature rise of the flexible light-emitting panel provided in the embodiment of the present application and the related art. In which, the embodiment 1 is Figure 14 the scheme of heat equalization first and then heat conduction, and the embodiment 2 is Figure 15The diagram illustrates a preheating followed by homogenization heating scheme. The overall temperature difference refers to the difference between the highest and lowest temperatures of the flexible light-emitting panel, while the maximum temperature rise refers to the maximum difference between the temperature of the flexible light-emitting panel and the ambient temperature.

[0107] Depend on Figure 16 It can be seen that the overall temperature difference of the flexible light-emitting panel in Example 1 is 5.4℃, the overall temperature difference of the flexible light-emitting panel in Example 2 is 7.05℃, and the overall temperature difference of the flexible light-emitting panel provided by related technologies is 8.8℃. Among them, the overall temperature difference of 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.

[0108] Depend on Figure 17 It can be seen that the maximum temperature rise measured by the flexible light-emitting panel in Example 1 is 20.7℃, the maximum temperature rise measured by the flexible light-emitting panel in Example 2 is 22.6℃, and the maximum temperature rise measured by the flexible light-emitting panel provided by the related technology is 23.5℃. Among them, the maximum temperature rise measured by the flexible light-emitting panel in Example 1 is the smallest, which is 1.9℃ lower than that in Example 2 and 2.8℃ lower than that in the related technology. That is, the scheme of first heat equalization and then heat conduction can achieve a smaller maximum temperature rise and a better heat dissipation effect.

[0109] based on Figure 16 and Figure 17 The results of the temperature rise test show 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 solution of heat dissipation first and then heat conduction can achieve better heat dissipation effect and temperature uniformity.

[0110] 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.

[0111] 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 dissipation layer 112b, and is bonded to both the metal support layer 112a and the heat dissipation layer 112b, thereby fixing the metal support layer 112a and the heat dissipation layer 112b. Figure 14In the illustrated embodiment, the first adhesive layer 112c can also be located between the heat-diffusing layer 112b and the panel body 111, and the first adhesive layer 112c is adhered to the heat-diffusing layer 112b and the panel body 111 respectively. In this case, the first adhesive layer 112c can fix the heat-diffusing structure 112 to the back surface M2 of the panel body 111. Figure 15 In the illustrated embodiment, the first adhesive layer 112c can also be located between the metal support layer 112a and the panel body 111, and the first adhesive layer 112c is adhered to the metal support layer 112a and the panel body 111 respectively. In this case, the first adhesive layer 112c can fix the heat-diffusing structure 112 to the back surface M2 of the panel body 111.

[0112] For example, the first adhesive layer 112c can be a heat-conducting glue, so as to improve the heat conductivity between the panel body 111 and the heat-diffusing structure 112, and improve the heat conductivity between the metal support layer 112a and the heat-diffusing layer 112b, thereby improving the heat-diffusing rate.

[0113] Optionally, referring to Figure 18 , Figure 18 is another cross-sectional structure schematic diagram of a beauty mask provided by the embodiment of the present application. The beauty mask 10 further comprises 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 have light-transmitting property, so as to avoid affecting the light-emitting brightness of the flexible light-emitting panel 11, thereby avoiding 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 silica gel.

[0114] The beauty mask 10 can further comprise a second adhesive layer 15, which is located between the protective layer 14 and the panel body 111, and the second adhesive layer 15 is adhered to the protective layer 14 and the panel body 111 respectively. For example, the second adhesive layer 15 can be an optical transparent glue, so as to avoid affecting the light-emitting brightness of the flexible light-emitting panel 11, thereby avoiding the beauty effect of the beauty mask.

[0115] The flexible light-emitting panel 11 can further include a driving chip 113 located on the panel body 111, and one end of the panel body 111 provided with the driving chip 113 can be bent to the side of the heat dissipation structure 112 away from the panel body 111, so that the driving chip 113 with high heat can be closer to the outside, facilitating heat exchange with air, thereby improving the heat dissipation effect. In some embodiments, the driving chip 113 is located on a flexible circuit board, one end of the flexible circuit board is connected to the panel body 111, and the other end of the flexible circuit board is bent to the side of the heat dissipation structure 112 away from the panel body 111, so that the driving chip 113 with high heat can be closer to the outside, thereby improving the heat dissipation effect.

[0116] In the embodiments of the present application, the form of the beauty mask can include multiple cases:

[0117] In one case, the beauty mask can be in a fixed form. In order to better fit the facial features of the user, the beauty mask can be a three-dimensional curved surface structure that fits the face shape. In this way, the distance between the beauty mask and the face is less different in various areas, thereby improving the uniformity of the light intensity on the face, and further improving the beauty effect and facilitating wearing. Since the face has a certain undulation, especially at the nose bridge and forehead, the beauty mask needs a greater degree of curvature. Therefore, in the beauty mask provided by the embodiments of the present application, the number of flexible light-emitting panels can be one or multiple flexible light-emitting panels spliced, which is not limited by the embodiments of the present application.

[0118] In another case, the beauty mask can be in a non-fixed flexible form, that is, the beauty mask can change form, which can improve the applicability of the beauty mask to various face shapes, thereby improving the user experience. The following two exemplary embodiments are described:

[0119] In the first embodiment, the beauty mask can change form once, please refer to Figure 18 and Figure 19 , Figure 19 is a schematic diagram of a transformation process of a beauty mask provided by the embodiments of the present application, 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 has plasticity at high temperature and elasticity at low temperature. 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 13-150 microns, so that the metal support layer 112a can be bent. In this way, the flexible light-emitting panel 11 can be deformed once.

[0120] The flexible light-emitting panel 11 is configured to deform in a direction towards the shell 13 when the user wears the beauty mask 10 for the first time. Since the flexible light-emitting panel 11 can deform once, the adaptability of the flexible light-emitting panel 11 to the face shape of the user can be improved.

[0121] It should be noted that, Figure 19 The initial shape of the flexible light-emitting panel 11 shown is a planar structure, but the embodiments of the present application are not limited thereto, and the initial shape 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.

[0122] Optionally, the protective layer 14 can be made of a material with superplasticity, so that the protective layer 14 has good ductility and fluidity. When another user uses the beauty mask 10, the protective layer 14 can deform slightly according to the principle of plasticine, so that the beauty mask 10 is fitted to 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.

[0123] In a second embodiment, the beauty mask can change multiple times, please refer to Figure 18 and Figure 20 , Figure 20 is a schematic diagram of another deformation process of the beauty mask provided by the embodiments of the present application. 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 the initial shape after deformation.

[0124] The flexible light-emitting panel 11 is configured to deform in a direction towards the shell 13 when the user wears the beauty mask 10, and to return to the initial shape after the user removes the beauty mask 10. Since the flexible light-emitting panel 11 can return to the initial shape after deformation, the shape of the flexible light-emitting panel 11 can match the face shapes of different users, thereby improving the compatibility of the flexible light-emitting panel 11 to the face shapes of different users and meeting the use requirements of different users.

[0125] It should be noted that, Figure 20 The initial shape of the flexible light-emitting panel 11 shown is a planar structure, but the embodiments of the present application are not limited thereto, and the initial shape 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.

[0126] In summary, the embodiment of the present application provides a beauty mask, wherein a heat-conducting plate is arranged between the flexible light-emitting panel and the shell, and the heat-conducting plate is in contact with the heat-dissipating structure in the flexible light-emitting panel. In this way, during long-term lighting of the flexible light-emitting panel, the heat of the panel body is first diffused by the heat-dissipating structure and transmitted to the heat-conducting plate, and then the heat-conducting plate can timely conduct the heat to the outside, so as to avoid scalding of the user, thereby improving the use experience of the beauty mask.

[0127] On the other hand, the embodiment of the present application also provides a beauty instrument, which comprises a wearing part and a beauty mask connected with the wearing part. For example, the wearing part can comprise a strap and the like.

[0128] Since the beauty instrument comprises the beauty mask provided by any of the above-mentioned embodiments, the beauty instrument can also have similar effects, that is, the use experience of the beauty instrument can be improved.

In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0130] In the present application, the term "at least one of A and B" is only used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, at least one of A and B can mean that A exists alone, A and B exist together, and B exists alone.

[0131] It should be noted that in the drawings, the sizes of the layers and regions can be exaggerated for clarity. Moreover, it will be 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 layer, or intervening layers can also be present. In addition, it will be understood that when an element or layer is referred to as being "under" another element or layer, it can be directly under the other element or layer, or one or more intervening layers or elements can also be present. In addition, it can also be understood that when a layer or element is referred to as "between" two layers or two elements, it can be the only layer between the two layers or two elements, or one or more intervening layers or elements can also be present.
