[0037] An embodiment of the present invention provides a phototherapy device, Figure 1 It is a schematic cross-sectional view of a phototherapy device provided by an embodiment of the present invention, Figure 2 It is a schematic view of a first surface provided by an embodiment of the present invention, Figure 3 It is a schematic view of another first surface provided by an embodiment of the present invention, referring to Figures 1 - 3 , the phototherapy device includes:

[0038] A substrate 10 and a light-emitting structure layer 20 disposed on one side of the substrate 10, and the light emitted by the light-emitting structure layer 20 is emitted through the substrate 10;

[0039] The substrate 10 includes a first surface 11 and a second surface 12. The first surface 11 is located on the side of the substrate 10 away from the light-emitting structure layer 20. The second surface 12 intersects with the first surface 11, and the second surface 12 surrounds the first surface 11;

[0040] The first surface 11 is provided with a plurality of first openings 101, and the depth of the first openings 101 is less than the thickness of the substrate 10; the second surface 12 is provided with a plurality of second openings 102, and each first opening 101 communicates with at least one second opening 102; a sweat discharging layer 30 is disposed in the first openings 101 and the second openings 102, and the sweat discharging layer 30 is configured to discharge the sweat entering the first openings 101 from the first surface 11 through the second openings 102.

[0041] Wherein, the substrate 10 may be formed of an organic polymer material such as PET, PEN, PI, etc., or the substrate 10 may be a glass substrate, a metal substrate or a plastic substrate. The light-emitting structure layer 20 may include at least one of an OLED light-emitting structure, an LED light-emitting structure and a laser light-emitting structure. Exemplarily, the light-emitting structure layer 20 may only include at least one OLED light-emitting structure, or may only include a plurality of LED light-emitting structures, or may only include a laser light-emitting structure, or may include any two of an OLED light-emitting structure, an LED light-emitting structure and a laser light-emitting structure, or all three. In addition, the light therapy device may further include a protective layer 40 for protecting the light-emitting structure layer 20.

[0042] The light emitted by the light-emitting structure layer 20 is emitted through the substrate 10. When the light therapy device is applied, the user is located on the side of the substrate 10 away from the light-emitting structure layer 20. By providing the first openings 101 on the first surface 11, the second openings 102 on the second surface 102, and disposing the sweat discharging layer 30 in the first openings 101 and the second openings 102, during the light therapy process, the sweat on the user's skin surface can enter the sweat discharging layer 30 through the first openings 101 and be discharged through the second openings 102 by the sweat discharging layer 30, improving the user's comfort and avoiding excessive sweat from accumulating on the surface of the light therapy device and entering the interior of the light therapy device, corroding the light-emitting structure layer 20, etc., and affecting the service life of the light therapy device.

[0043] Specifically, referring to Figure 2 and Figure 3 , the first openings 101 may include holes and grooves. When the first openings 101 include grooves, they may extend to the edge of the substrate 101. In this way, after the sweat discharging layer 30 in the first openings 101 absorbs sweat, the sweat can be discharged to the outside through the edge of the substrate 10, and the contact area between the sweat discharging layer 30 and the outside is larger, and the sweat discharging speed is faster. Similarly, the second openings 102 may also include holes and grooves. When the second openings 102 include grooves, the contact area between the sweat discharging layer 30 in the second openings 102 and the outside is larger, and the sweat discharging speed is faster. In addition, the depths of different first openings 101 may be the same or different. One first opening 101 may communicate with one second opening 102, or may communicate with two or more second openings 102. The second openings 102 may penetrate the substrate 10 or may not penetrate the substrate 10.

[0044] In addition, after forming the first opening 101 and the second opening 102 on the substrate 10, the sweat discharging layer 30 can be prepared in the first opening 101 and the second opening 102 by the pulling method.

[0045] In the embodiment of the present invention, a plurality of first openings 101 are provided on the first surface 11 of the substrate 10, and a plurality of second openings 102 are provided on the second surface 12 of the substrate 10. Each first opening 101 communicates with at least one second opening 102; a sweat discharging layer 30 is provided in the first opening 101 and the second opening 102. The sweat discharging layer 30 is used to discharge the sweat entering the first opening 101 from the first surface 11 through the second opening 102, so that the sweat of the user during the phototherapy process can enter the sweat discharging layer 30 through the first opening 101 and be discharged through the second opening 102 by the sweat discharging layer 30, improving the comfort of the user, and avoiding excessive sweat from gathering on the surface of the phototherapy device and entering the interior of the phototherapy device to corrode the light emitting structure layer 20, etc., ensuring that the phototherapy device has a long service life.

[0046] Figure 4 It is a schematic cross-sectional view of another phototherapy device provided by the embodiment of the present invention. Optionally, refer to Figure 4 , the sweat discharging layer 30 includes a first layer 31, a second layer 32 and a third layer 33 which are sequentially stacked. The hydrophilicity of the first layer 31, the second layer 32 and the third layer 33 gradually increases; the first layer 31 includes first pores, the second layer 32 includes second pores, and the third layer 33 includes third pores; the first pores, the second pores and the third pores decrease in sequence;

[0047] The first layer 31 and the second layer 32 are disposed in the first opening 101, and the first layer 31 is located on the side of the second layer 32 adjacent to the first surface 11, and the third layer 33 is disposed in the second opening 102.

[0048] Specifically, the first pores, the second pores and the third pores are the pores of the materials of the first layer 31, the second layer 32 and the third layer 33 themselves. The hydrophilicity of the first layer 31, the second layer 32 and the third layer 33 gradually increases, and the first pores, the second pores and the third pores decrease in sequence, that is, the sweat discharging layer 30 has a bidirectional porosity, so that the sweat discharging layer can play a certain heat dissipation role while discharging sweat, further improving the user experience.

[0049] In addition, the hydrophilicity of the first layer 31, the second layer 32, and the third layer 33 gradually increases, enabling sweat to be quickly absorbed by the second layer 32 after entering the first layer 31, and then quickly absorbed by the third layer 33 after entering the second layer 32, and volatilized into the environment through the third layer 33. Moreover, the first pores, the second pores, and the third pores decrease in sequence, forming a capillary-like structure inside the sweat discharge layer 30. This capillary structure allows sweat to flow from the area with larger pores to the area with smaller pores. Therefore, by setting the first pores, the second pores, and the third pores to decrease in sequence, sweat can be transferred from the first layer 31 to the third layer 33 faster and discharged to the outside faster.

[0050] Optionally, the pore diameter of the first pores in the first layer 31 is 5 - 100 μm, preferably 5 - 50 μm; the pore diameter of the second pores in the second layer 32 is 0.1 - 5 μm, preferably 0.5 - 2 μm; the pore diameter of the third pores in the third layer 33 is 10 - 100 nm, preferably 40 - 60 nm. The pore diameters of the membrane structure within the preferred range not only have a better sweat conduction effect but also a more obvious light diffusion effect. Thus, not only can sweat be effectively removed, but also the efficiency of the device can be improved.

[0051] Optionally, the density of the pores is 10 - 100 per square centimeter, preferably 40 - 80. Within this range, the pore density can be effectively set according to the sweat density of the human body to achieve comprehensive and effective sweat removal.

[0052] Figure 5 It is a schematic cross-sectional view of another phototherapy device provided by an embodiment of the present invention. Optionally, referring to Figure 5 , the sweat discharge layer 30 protrudes from the first surface 11, and / or, the sweat discharge layer 30 protrudes from the second surface 12. Exemplarily, the first layer 31 protrudes from the first surface 11, and the third layer 33 protrudes from the second surface 12.

[0053] Specifically, when the sweat discharge layer 30 protrudes from the first surface 11, it means that the sweat discharge layer 30 extends outside the substrate 10. In this way, the contact area between the sweat discharge layer 30 and the outside is larger, and sweat can enter the sweat discharge layer 30 faster and be discharged by the sweat discharge layer 30. When the sweat discharge layer 30 protrudes from the second surface 12, it means that the sweat discharge layer 30 extends outside the substrate 10. In this way, the contact area between the sweat discharge layer and the outside is larger, and sweat can be dissipated into the external environment faster and the heat dissipation speed is faster.

[0054] Figure 6 It is a schematic cross-sectional view of another phototherapy device provided by an embodiment of the present invention. Optionally, referring to Figure 6 , along the direction parallel to the first surface 11, the size of the part of the sweat discharge layer 30 protruding from the first surface 11 is larger than the size of the first opening 101; along the direction parallel to the second surface 12, the size of the part of the sweat discharge layer 30 protruding from the second surface 12 is larger than the size of the second opening 102.

[0055] Specifically, the size of the part of the sweat-absorbing layer 30 protruding from the first surface 11 is larger than the size of the first opening 101. It can be that the size of the part of the sweat-absorbing layer 30 protruding from the first surface 11 in a certain direction or several directions parallel to the first surface 11 is larger than the size of the first opening 101 in the corresponding direction. Such a setting makes the contact area between the sweat-absorbing layer 30 and the outside larger, the sweat-absorbing area larger, and the sweat can enter the sweat-absorbing layer 30 faster and be discharged by the sweat-absorbing layer 30.

[0056] The size of the part of the sweat-absorbing layer 30 protruding from the second surface 12 is larger than the size of the second opening 102. It can be that the size of the part of the sweat-absorbing layer 30 protruding from the second surface 12 in a certain direction or several directions parallel to the second surface 12 is larger than the size of the second opening 102 in the corresponding direction. Such a setting makes the contact area between the sweat-absorbing layer 30 and the outside larger, the sweat can be dissipated into the external environment faster, and the heat dissipation speed is faster.

[0057] The shape of the part of the sweat-absorbing layer 30 protruding from the first surface 11 and the shape of the part of the sweat-absorbing layer 30 protruding from the second surface 12 can be set as circular, oval, triangular, square or other polygons, and can also be set as other shapes according to the needs of sweating and heat dissipation.

[0058] Optionally, the part of the sweat-absorbing layer 30 protruding from the first surface 11 is distributed on the first surface 11 in a tree-like or net-like shape, and the part of the sweat-absorbing layer 30 protruding from the second surface 12 is distributed on the second surface 12 in a tree-like or net-like shape.

[0059] Specifically, the part of the sweat-absorbing layer 30 protruding from the first surface 11 is distributed on the first surface 11 in a tree-like or net-like shape, making the contact area between the sweat-absorbing layer 30 and the outside larger, the sweat-absorbing area larger, and the sweat can enter the sweat-absorbing layer 30 faster and be discharged by the sweat-absorbing layer 30. The part of the sweat-absorbing layer 30 protruding from the second surface 12 is distributed on the second surface 12 in a tree-like or net-like shape, making the contact area between the sweat-absorbing layer 30 and the outside larger, the sweat can be dissipated into the external environment faster, and the heat dissipation speed is faster.

[0060] Figure 7 It is a schematic cross-sectional view of another phototherapy device provided by an embodiment of the present invention. Optionally, referring to Figure 7 , the parts of the sweat-absorbing layer 30 protruding from the first surface 11 in the multiple first openings 101 are connected to each other, and the parts of the sweat-absorbing layer 30 protruding from the second surface 12 in the multiple second openings 102 are connected to each other;

[0061] The multiple second openings communicate with each other inside the substrate 10.

[0062] Specifically, the parts of the sweat-absorbing layer 30 protruding from the first surface 11 among the multiple first openings 101 are interconnected. On the one hand, the sweat-absorbing layer 30 has a larger distribution area on the first surface 11 of the substrate 10, and a larger sweat-absorbing area. On the other hand, after any area of the part of the sweat-absorbing layer 30 protruding from the first surface 11 absorbs sweat, the sweat can be discharged through the multiple first openings 101, and there are more sweat-discharging paths, further improving the sweat-discharging speed.

[0063] In addition, the parts of the sweat-absorbing layer 30 protruding from the second surface 12 among the multiple second openings 102 are interconnected. The sweat-absorbing layer 30 has a larger distribution area on the second surface 122, and a larger sweat-discharging area, further improving the sweat-discharging speed.

[0064] In addition, the multiple second openings communicate with each other inside the substrate 10, so that the multiple sweat-discharging paths communicate with each other. After the sweat-absorbing layer 30 in any one of the first openings 101 absorbs sweat, it can be discharged through the multiple second openings 102, further improving the sweat-discharging speed.

[0065] Figure 8 It is a schematic cross-sectional view of another phototherapy device provided by an embodiment of the present invention. Optionally, refer to Figure 8 , the part of the sweat-absorbing layer 30 protruding from the first opening 101 is distributed throughout the first surface 11;

[0066] And / or, the substrate 10 includes a first sub-layer 111 and a second sub-layer 112. The second sub-layer 112 is disposed on the side of the first sub-layer 111 adjacent to the light-emitting structure layer 20. There is a gap between the first sub-layer 111 and the second sub-layer 112, and the gap is the second opening 102.

[0067] Specifically, the part of the sweat-absorbing layer 30 protruding from the first opening 101 is distributed throughout the first surface 11, that is, the sweat-absorbing layer 30 extends to the edge of the substrate 10. In this way, the contact area between the sweat-absorbing layer 30 and the skin is larger, and the sweat-absorbing area is larger, and the sweat can be discharged faster. In addition, when the sweat-absorbing layer 30 is distributed on the entire first surface 11, the sweat-absorbing layer 30 can be provided with multiple through holes, and the vertical projection of the through holes on the substrate 10 does not overlap with the first opening 101. With this setting, while the sweat-absorbing layer 30 has a large sweat-absorbing area, it has a high light transmittance, making the phototherapy effect better. Exemplarily, the sweat-absorbing layer 30 can be distributed in a mesh shape.

[0068] In addition, the substrate 10 includes a first sub-layer 111 and a second sub-layer 112. The second sub-layer 112 is disposed on the side of the first sub-layer 111 adjacent to the light-emitting structure layer 20. There is a gap between the first sub-layer 111 and the second sub-layer 112, and the gap is the second opening 102.

[0069] That is, the sweat discharging layer 30 is distributed throughout the substrate 10. With this arrangement, during manufacturing, the first sub-layer 111 can be fabricated first, then the sweat discharging layer 30 can be fabricated over the entire surface, and then the second sub-layer 112 can be fabricated, reducing the manufacturing process difficulty of the sweat discharging layer 30.

[0070] Exemplarily, the third layer 33 is distributed throughout the substrate 10, such that the sweat absorption area of the third layer 33 is larger, enabling the sweat to be drawn from the second layer 32 more quickly and discharged more rapidly. Moreover, the manufacturing process of the third layer 33 is simpler and only requires a whole-layer coating on the surface of the first sub-layer 111.

[0071] Optionally, multiple first openings 101 are evenly distributed on the first surface 11, and multiple second openings 102 are evenly distributed along the direction surrounding the first surface 11.

[0072] Specifically, the multiple first openings 101 are evenly distributed on the first surface 11, enabling the sweat at various positions of the light therapy device to be discharged at a relatively fast speed. In addition, the light therapy device can be partitioned according to the specific usage scenario of the light therapy device, with more first openings 101 provided in the area where the skin in contact is more prone to sweating, and fewer first openings 101 provided in the area where the skin in contact sweats less.

[0073] The multiple second openings 102 are evenly distributed along the direction surrounding the first surface 11, enabling the sweat at each position on the side surface of the substrate 10 to be discharged outward, thereby increasing the sweat discharging speed.

[0074] Optionally, the material used for the first layer 31 includes olefin or polyamide, the material used for the second layer 32 includes thermoplastic polyurethane, and the material used for the third layer 22 includes cellulose.

[0075] Specifically, olefin, polyamide, thermoplastic polyurethane, and cellulose all have good light transmittance, and the preparation process is simple. By using the above materials to fabricate the sweat discharging layer 30, while ensuring good sweat discharging performance of the sweat discharging layer 30, the manufacturing process is reduced, and the light emitted by the light emitting structure layer 20 can pass through more, without affecting the light therapy effect.

[0076] The film layer structures of different materials are more likely to meet the designs of different pores, and the multifunctionality of the film layer structure can be realized. For example, the first layer 31 preferably uses olefin-based and polyamide-based materials, which have certain biological safety; the second layer 32 preferably uses polyurethane-based materials, which have certain flexibility and can effectively ensure the toughness and reliability of the film layer structure; the third layer 33 selects cellulose-based materials, which are more convenient in the preparation process.

[0077] In addition, the first layer 31, the second layer 32, and the third layer 33 are respectively made of at least one of the following materials: bionic gold, urethane compounds, aldehyde compounds, olefin compounds, aromatic hydrocarbon compounds, epoxy compounds, silicon oxide, silicon oxynitride, and titanium oxide.

[0078] Specifically, three materials with gradually increasing hydrophilicity can be selected from bionic gold, urethane compounds, aldehyde compounds, olefin compounds, aromatic hydrocarbon compounds, epoxy compounds, silicon oxide, silicon oxynitride, and titanium oxide to make the first layer 31, the second layer 32, and the third layer 33. Bionic gold, urethane compounds, aldehyde compounds, olefin compounds, aromatic hydrocarbon compounds, epoxy compounds, silicon oxide, silicon oxynitride, and titanium oxide all have good light transmittance, and the preparation process is simple. Using the above materials to make the sweat-absorbing layer 30 can ensure good sweat absorption of the sweat-absorbing layer 30 while reducing the manufacturing process, and enable more light emitted by the light-emitting structure layer 20 to pass through, without affecting the light therapy effect.

[0079] In addition, Figure 9 is a schematic cross-sectional view of another light therapy device provided by an embodiment of the present invention. Optionally, referring to Figure 9 , when the first opening 101 is a hole, the first opening 101 can also penetrate through the light-emitting structure layer 20 and the protective layer 40, and the sweat-absorbing layer 30 fills the entire first opening 101 and the second opening 102. In this way, after the sweat-absorbing layer 30 absorbs sweat through the first opening 101, it can also be discharged through the surface of the protective layer 40, further improving the sweat discharge speed.

[0080] Figure 10 is a schematic cross-sectional view of another light therapy device provided by an embodiment of the present invention. Referring to Figure 10 , Figure 10 exemplarily shows the distribution modes of the first layer 31, the second layer 32, and the third layer 33.
