Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0033] It should be noted that the terms "first", "second", and the like in the description and in the claims of the present application and above-described accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular sequential or chronological order. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0034] Figure 1 is a structural schematic diagram of a phototherapy device provided according to an embodiment of the present application, referring to Figure 1 The present application provides a phototherapy device, which comprises a substrate 10 and a light-emitting structure layer 20 arranged on one side of the substrate 10; the substrate 10 is provided with a plurality of through holes 40, the through holes 40 penetrating the substrate 10 and the light-emitting structure layer 20; and a sweat layer 50 is arranged in the through holes 40.

[0035] The substrate 10 can be formed of PET, PEN, PI or other organic polymer materials, and the substrate 10 can also be a glass substrate, a metal substrate or a plastic substrate. The light-emitting structure layer 20 can include at least one of an OLED light-emitting structure, an LED light-emitting structure and a laser light-emitting structure. For example, the light-emitting structure layer 20 can include only at least one OLED light-emitting structure, only a plurality of LED light-emitting structures, only a laser light-emitting structure, or any two or all of the OLED light-emitting structure, the LED light-emitting structure and the laser light-emitting structure. The sweat layer 50 can be prepared in the through holes 40 by a pulling process.

[0036] The phototherapy device generates a large amount of heat during operation, and the user's skin is prone to sweating. The sweat on the surface of the skin can be discharged through the sweat layer 50 in the through holes 40, which can improve the user's comfort and avoid excessive sweat from accumulating on the surface of the phototherapy device and entering the interior of the phototherapy device, corroding the light-emitting structure layer 20 and affecting the service life of the phototherapy device.

[0037] Exemplarily, the light emitted by the light-emitting structure layer 20 is emitted out of the substrate 10, and when the phototherapy device is applied, the user is located on the side of the substrate 10 away from the light-emitting structure layer 20, at this time, the sweat layer 50 absorbs sweat from the side of the substrate 10 and discharges the sweat through the side of the light-emitting structure layer 20. When the light emitted by the light-emitting structure layer 20 is emitted out of the substrate 10, and when the phototherapy device is applied, the user is located on the side of the light-emitting structure layer 20 away from the light-emitting structure layer 20, at this time, the sweat layer 50 absorbs sweat from the side of the light-emitting structure layer 20 and discharges the sweat through the side of the substrate 10.

[0038] The technical scheme of the embodiment of the present application is that a plurality of through holes are arranged in the substrate, the through holes penetrate the substrate and the light-emitting structure layer, and the sweat layer is arranged in the through holes. During the working process of the phototherapy device, the sweat layer can absorb and discharge the sweat generated by the human skin, so that the comfort of the user is not affected by too much sweat during the phototherapy, thereby improving the user experience, and timely absorption and discharge of the sweat can avoid affecting the phototherapy device, so that the phototherapy device can have a longer service life.

[0039] Figure 2 is a structural schematic diagram of a sweat layer according to an embodiment of the present application, Figure 3 is a structural schematic diagram of a sweat layer distribution according to an embodiment of the present application, Figure 4 is a structural schematic diagram of another sweat layer distribution according to an embodiment of the present application; optionally, referring to Figure 2 The sweat layer 50 includes a first layer 51, a second layer 52 and a third layer 53 which are sequentially stacked, the hydrophilicity of the first layer 51, the second layer 52 and the third layer 53 gradually increases, the first layer 51 includes first pores 511, the second layer 52 includes second pores 521, and the third layer 53 includes third pores 531; the first pores 511, the second pores 521 and the third pores 531 sequentially decrease.

[0040] Specifically, the first pores 511, the second pores 521 and the third pores 531 are the pores of the materials of the first layer 51, the second layer 52 and the third layer 53 respectively. The hydrophilicity of the first layer 51, the second layer 52 and the third layer 53 gradually increases, and the first pores 511, the second pores 521 and the third pores 531 sequentially decrease, that is, the sweat layer 50 has a bidirectional porosity, so that the sweat layer 50 can also play a certain heat dissipation effect while discharging sweat, further improving the user experience.

[0041] In addition, the hydrophilicity of the first layer 51, the second layer 52 and the third layer 53 gradually increases, so that the sweat can be quickly absorbed by the second layer 52 after entering the first layer 51, and can be quickly absorbed by the third layer 53 after entering the second layer 52, and volatilized to the environment through the third layer 53, and the first pore 511, the second pore 521 and the third pore 531 are sequentially reduced, so that a capillary structure is formed inside the sweat discharge layer 50, and the capillary structure allows the sweat to flow from a large-pore area to a small-pore area, so that the first pore 511, the second pore 521 and the third pore 531 are sequentially reduced, so that the sweat can be quickly transmitted from the first layer 31 to the third layer 33 and quickly discharged to the outside.

[0042] Optionally, the pore diameter of the first pore 511 is 5-100 μm, preferably 5-50 μm; the pore diameter of the second pore 521 is 0.1-5 μm, preferably 0.5-2 μm; and the pore diameter of the third pore 531 is 10-100 nm, preferably 40-60 nm. The film structure pore diameter in the preferred range not only has a better sweat guiding effect, but also has a more obvious light diffusion effect, thereby effectively removing sweat and improving the efficiency of the device.

[0043] Optionally, the density of the pores is 10-100 per square centimeter, preferably 40-80 per square centimeter. In this range, the pore density can be effectively set according to the human sweat discharge density to achieve comprehensive and effective sweat removal.

[0044] Reference Figure 3 The light emitted by the light-emitting structure layer 20 is emitted from the substrate 10, the first layer 51 is arranged on the side of the second layer 52 adjacent to the substrate 10, or Figure 4 The light emitted by the light-emitting structure layer 20 is emitted away from the substrate 10, and the first layer 51 is arranged on the side of the second layer 52 adjacent to the light-emitting structure layer 20.

[0045] Specifically, Figure 3 Exemplarily, the light emitted by the light-emitting structure layer 20 is emitted from the substrate 10 to the human body, and is exemplarily projected to the face. Figure 4 Exemplarily, the light emitted by the light-emitting structure layer 20 is emitted away from the substrate 10 to the face. The sweat flows from the first layer 51 to the second layer 52, and from the second layer 52 to the third layer 53, achieving directional discharge of the sweat, so that the light therapy does not affect the comfort due to excessive sweat, and the timely discharge of the sweat protects the light therapy device.

[0046] Figure 5 is a structural schematic diagram of another light therapy device according to an embodiment of the present application, and Figure 5Optionally, the light therapy device further comprises a protective layer 30, the protective layer 30 is located on the side of the light-emitting structure layer 20 away from the substrate 10, and the through hole 40 penetrates the protective layer 30.

[0047] The protective layer 30 is configured to protect the light-emitting structure layer 20. When the light-emitting structure layer 20 comprises an OLED light-emitting structure, the substrate 10 can comprise a flexible substrate, and the protective layer 30 can comprise a flexible encapsulation layer, which protects the light-emitting structure layer 20 from water and oxygen. The substrate 10 can also comprise a rigid substrate, and the protective layer 30 can comprise a hard encapsulation layer. The sweat layer 50 fills the through hole 40 formed in the substrate 10, the light-emitting structure layer 20, and the protective layer 30.

[0050] Figure 8 is another structure diagram of the light therapy device according to an embodiment of the present application, referring to Figure 8 Optionally, the sweat layer 50 protrudes from the substrate 10; and / or, the sweat layer 50 protrudes from the protective layer 30.

[0051] Specifically, the sweat layer 50 protrudes from the substrate 10, and the sweat layer 50 on the side of the substrate 10 has a larger contact area with the external environment; and / or, the sweat layer 50 protrudes from the protective layer 30, and the sweat layer 50 on the side of the protective layer 30 has a larger contact area with the external environment.

[0052] When the light emitted by the light-emitting structure layer 20 is emitted through the substrate 10, a user is located on the side of the substrate 10, the sweat layer 50 protrudes from the substrate 10, the sweat layer 50 has a larger sweat absorption area, and sweat can enter the sweat layer 50 more quickly and be discharged by the sweat layer 50. The sweat layer 50 protrudes from the protective layer 30, and sweat can be emitted to the external environment more quickly and at a faster speed.

[0053] When the light emitted by the light-emitting structure layer 20 exits through the protective layer 30, the user is located on the side of the protective layer 30, the sweat-exhausting layer 50 protrudes from the protective layer 30, the sweat-exhausting area of the sweat-exhausting layer 50 is larger, and the sweat can enter the sweat-exhausting layer 50 more quickly and be exhausted by the sweat-exhausting layer 50. The sweat-exhausting layer 50 protrudes from the substrate 10, the sweat can be dissipated to the external environment more quickly, and the heat dissipation speed is faster.

[0054] With reference to the foregoing Figure 8 Optionally, the size of the part of the sweat-exhausting layer 50 protruding from the substrate 10 in a direction parallel to the surface of the substrate 10 away from the protective layer 30 is greater than the size of the through hole 40, and the size of the part of the sweat-exhausting layer 50 protruding from the protective layer 30 is greater than the size of the through hole 40.

[0055] Specifically, the size of the part of the sweat-exhausting layer 50 protruding from the substrate 10 can be greater than the size of the through hole 40 in one or more directions parallel to the surface of the substrate 10, so that the contact area of the sweat-exhausting layer 50 with the external environment is larger. The size of the part of the sweat-exhausting layer 50 protruding from the protective layer 30 can be greater than the size of the through hole 40 in one or more directions parallel to the surface of the protective layer 30, so that the contact area of the sweat-exhausting layer 50 with the external environment is larger. Thus, the sweat-exhausting area of the sweat-exhausting layer 50 is larger, the sweat can enter the sweat-exhausting layer 50 more quickly, and the sweat can be dissipated to the external environment more quickly, and the heat dissipation speed is faster.

[0056] In addition, the shape of the part of the sweat-exhausting layer 50 protruding from the substrate 10 and the shape of the part of the sweat-exhausting layer 50 protruding from the protective layer 30 can be circular, elliptical, triangular, square or other polygonal, and can also be other shapes according to the needs of sweat-exhausting and heat dissipation.

[0057] Optionally, the part of the sweat-exhausting layer 50 protruding from the substrate 10 is distributed on the surface of the substrate 10 in a tree shape or a net shape, and the part of the sweat-exhausting layer 50 protruding from the protective layer 30 is distributed on the surface of the protective layer 30 in a tree shape or a net shape.

[0058] Thus, the contact area of the sweat-exhausting layer 50 with the external environment is larger, the sweat-exhausting area is larger, the sweat can enter the sweat-exhausting layer 50 more quickly, the sweat can be dissipated to the external environment more quickly, and the heat dissipation speed is faster.

[0059] Figure 9 is a structural schematic diagram of another phototherapy device according to an embodiment of the present application, with reference to Figure 9 Optionally, the parts of the sweat-exhausting layer 50 protruding from the substrate 10 in the plurality of through holes 40 are connected to each other, and / or the parts of the sweat-exhausting layer 50 protruding from the protective layer 30 in the plurality of through holes 40 are connected to each other.

[0060] Specifically, when the light emitted by the light-emitting structure layer 20 is emitted through the substrate 10, the user is located on the side of the substrate 10 during phototherapy, and the portions of the sweat-removing layer 50 protruding from the substrate 10 that are in the plurality of through holes 40 are connected to each other. On the one hand, the distribution area of the sweat-removing layer 50 on the surface of the substrate 10 is larger, and the sweat-absorbing area is larger. On the other hand, after sweat is absorbed by any area of the portions of the sweat-removing layer 50 protruding from the substrate 10, the sweat can be discharged through the plurality of through holes 40, the sweat-removing path is more, and the sweat-removing speed is further improved.

[0061] The portions of the sweat-removing layer 50 protruding from the protective layer 30 that are in the plurality of through holes are connected to each other. The distribution area of the sweat-removing layer 50 on the surface of the protective layer 30 is larger, and the sweat-absorbing area is larger. Sweat can be more quickly dissipated to the external environment, and the heat dissipation speed is faster.

[0062] When the light emitted by the light-emitting structure layer 20 is emitted through the protective layer 30, the user is located on the side of the protective layer 30 during phototherapy, and the portions of the sweat-removing layer 50 protruding from the protective layer 30 that are in the plurality of through holes 40 are connected to each other. On the one hand, the distribution area of the sweat-removing layer 50 on the surface of the protective layer 30 is larger, and the sweat-absorbing area is larger. On the other hand, after sweat is absorbed by any area of the portions of the sweat-removing layer 50 protruding from the protective layer 30, the sweat can be discharged through the plurality of through holes 40, the sweat-removing path is more, and the sweat-removing speed is further improved. The portions of the substrate 10 protruding from the protective layer 30 that are in the plurality of through holes are connected to each other. The distribution area of the sweat-removing layer 50 on the surface of the substrate 10 is larger, and the sweat-absorbing area is larger. Sweat can be more quickly dissipated to the external environment, and the heat dissipation speed is faster.

[0063] Optionally, the portions of the sweat-removing layer 50 protruding from the substrate 10 can be distributed on the surface of the substrate 10 in an integral layer, that is, the sweat-removing layer 50 extends to the edge of the substrate 10. In addition, when the sweat-removing layer 50 is distributed on the surface of the substrate 10 in an integral layer, the sweat-removing layer 50 can be provided with a plurality of first openings. The vertical projection of the first opening on the substrate 10 does not overlap the through hole 40. In this way, the sweat-removing layer 50 has a higher light transmittance, so that the phototherapy effect is better. Exemplarily, the sweat-removing layer 50 can be distributed in a mesh shape on the surface of the substrate.

[0064] The portions of the sweat-removing layer 50 protruding from the protective layer 30 can be distributed on the surface of the protective layer 30 in an integral layer, that is, the sweat-removing layer 50 extends to the edge of the protective layer 30. In addition, when the sweat-removing layer 50 is distributed on the surface of the protective layer 30 in an integral layer, the sweat-removing layer 50 can be provided with a plurality of second openings. The vertical projection of the second opening on the protective layer 30 does not overlap the through hole 40. In this way, the sweat-removing layer 50 has a higher light transmittance, so that the phototherapy effect is better. Exemplarily, the sweat-removing layer 50 can be distributed in a mesh shape on the surface of the protective layer 30.

[0065] Continuing to refer to Figure 9 Optionally, the plurality of through holes 40 are uniformly distributed on the protective layer 30.

[0066] Specifically, the plurality of through holes 40 are uniformly distributed in the protective layer 30, so that the sweat at each position of the phototherapy device can be discharged at a faster speed. In addition, the phototherapy device can be partitioned according to the specific use scene of the phototherapy device, more through holes 40 are arranged in the area where the skin contacted is more likely to sweat, and less through holes 40 are arranged in the area where the skin contacted is less likely to sweat. The specific number of through holes 40 can also be set according to actual needs, and the embodiment of the present application does not limit this.

[0067] Continuing to refer to Figure 9 Optionally, the material adopted by the first layer 51 includes olefin or polyamide, the material adopted by the second layer 52 includes thermoplastic polyurethane, and the material adopted by the third layer 53 includes cellulose.

[0068] Specifically, the olefin and the polyamide, the thermoplastic polyurethane, and the cellulose all have good light transmittance, and the preparation process is simple. The sweat discharge layer 50 is made of the above-mentioned materials, which ensures good sweat discharge of the sweat discharge layer 50, reduces the manufacturing process, and enables more light emitted by the light-emitting structure layer 20 to be transmitted, so as not to affect the phototherapy effect.

[0069] The film layer structure of different materials is more likely to meet the design of different pores, and the multifunctionality of the film layer structure can be realized. For example, the first layer 51 is preferably olefin or polyamide material, which has certain biological safety; the second layer 52 is preferably polyurethane material, which has certain flexibility, so as to effectively ensure the toughness and reliability of the film layer structure; and the third layer 53 is preferably cellulose material, which is more convenient in preparation process.

[0070] Alternatively, the first layer 51, the second layer 52, and the third layer 53 respectively adopt at least one of the following materials: biomimetic gold, urethane compound, aldehyde compound, olefin compound, aromatic hydrocarbon compound, epoxy compound, silicon oxide, silicon oxynitride, and titanium oxide.

[0071] Specifically, three materials with gradually increasing hydrophilicity can be selected from biomimetic gold, urethane compound, aldehyde compound, olefin compound, aromatic hydrocarbon compound, epoxy compound, silicon oxide, silicon oxynitride, and titanium oxide to be made into the first layer 51, the second layer 52, and the third layer 53. The biomimetic gold, the urethane compound, the aldehyde compound, the olefin compound, the aromatic hydrocarbon compound, the epoxy compound, the silicon oxide, the silicon oxynitride, and the titanium oxide all have good light transmittance, and the preparation process is simple. The sweat discharge layer 50 is made of the above-mentioned materials, which ensures good sweat discharge of the sweat discharge layer 50, reduces the manufacturing process, and enables more light emitted by the light-emitting structure layer 20 to be transmitted, so as not to affect the phototherapy effect.

[0072] Figure 10is a structural schematic diagram of still another phototherapy device according to an embodiment of the present application, referring to Figure 10 Optionally, the protective layer 30 comprises an encapsulation layer 31 covering the sidewall of the through hole 40.

[0073] Specifically, the encapsulation layer 31 can effectively prevent water vapor, oxygen and other components in the atmosphere from entering the light-emitting structure layer 20; the encapsulation layer 31 covers the sidewall of the through hole 40, which protects the light-emitting structure layer 20 and thus prolongs the service life of the phototherapy device.

[0074] In addition, the protective layer 30 can further comprise a first protective film, which is the outermost film layer of the phototherapy device and is used to protect the internal mechanism of the phototherapy device. When the substrate 10 comprises a flexible substrate, the substrate 10 can also comprise a second protective film, which is located on the side of the flexible substrate away from the light-emitting structure layer 20 and is the outermost film layer of the phototherapy device and is used to protect the internal mechanism of the phototherapy device. The phototherapy device can also not comprise the first protective film and the second protective film, which are not specifically limited in the present embodiment.

[0075] In addition, Figure 11 is a structural schematic diagram of still another phototherapy device according to an embodiment of the present application, referring to Figure 11 The side surface of the substrate 10 can comprise a plurality of openings 101, each through hole 40 is in communication with at least one opening 101, and the sweat-wicking layer 50 fills the openings 101. In this way, the sweat-wicking layer 50 can further improve the sweat-wicking speed after absorbing sweat and discharging through the surface of the substrate 10.

[0076] Figure 12 is a structural schematic diagram of still another phototherapy device according to an embodiment of the present application, referring to Figure 12 , Figure 12 Exemplary distribution modes of the first layer 51, the second layer 52 and the third layer 53 are shown.

It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
