Description

Technical Field

[0001] At least one embodiment of the present disclosure relates to the field of hot compress eye masks, and in particular to a hot compress device and a hot compress eye mask. Background Art

[0002] With the acceleration of the process of electronic informatization in society, people are using electronic display products for longer and longer periods of time. Long-term stimulation of the eyes by the flickering screen will cause discomfort symptoms such as dryness and swelling, and may even cause symptoms such as poor blood circulation in the eyes, blurred vision, and even decreased vision, which will have a negative impact on life and work.

[0003] There are hot compress eye masks on the market to solve the above technical problems, but hot compress eye masks are usually invisible products. Users can only use this product when they stop working or other daily activities, which seriously limits the application of hot compress eye masks. Summary of the invention

[0004] The present disclosure provides a hot compress device, which can be applied to a visual hot compress eye mask. The hot compress device includes a lens assembly and a power module, the lens assembly includes a transparent conductive film and a transparent substrate for fixing the transparent conductive film, and the power module is electrically connected to the transparent conductive film. The transparent conductive film includes a metal grid.

[0005] After the power module is used to energize the metal grid, the metal grid can emit heat radiation, thereby achieving hot compress; in addition, the metal grid is light-transmissive, so that the hot compress eye mask with a hot compress device has a visual function, and the user can carry out daily life or work and other activities during the hot compress process.

[0006] For example, in a hot compress device provided in one embodiment of the first aspect of the present disclosure, the metal grid is made of an opaque metal material.

[0007] Metal materials with strong electrical and thermal conductivity (such as metal elements or alloys) are usually opaque. By utilizing the metal grid design in the aforementioned embodiment, the transparent conductive film can be made visually transparent. Therefore, the scheme of setting a metal grid in the hot compress device will not adversely affect the visibility of the hot compress device.

[0008] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the metal grid includes a plurality of meshes, and the plurality of meshes are evenly arranged in a plurality of rows and columns. The metal grid can be composed of metal wires (grid wires), and the metal wires surround the meshes. The metal wires are opaque. When the meshes are evenly arranged, the light transmittance of the metal grid (lens assembly) is uniform in visual effect, and the uneven light transmittance will not cause adverse effects on the user's vision.

[0009] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the transparent conductive film is located on the surface of the substrate.

[0010] For example, in a hot compress device provided in another embodiment of the first aspect of the present disclosure, the substrate includes a first substrate and a second substrate, and the transparent conductive film is sandwiched between the first substrate and the second substrate.

[0011] For example, the first substrate is located on the inner side of the lens assembly, the second substrate is located on the outer side of the lens assembly, and the thickness of the first substrate is smaller than the thickness of the second substrate.

[0012] In this solution, the first substrate is thinner than the second substrate, so the heat radiation generated by the metal grid can more easily pass through the first substrate and be more easily blocked by the second substrate, so that as much heat radiation generated by the metal grid as possible can be used for hot compress.

[0013] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the metal grid includes a plurality of first sub-grids arranged side by side and spaced apart from each other.

[0014] In this solution, since the subgrids are spaced apart from each other, when the metal grid is energized, the current flowing into any subgrid will not flow into other subgrids. Compared with the entire integrated grid structure, this is conducive to uniform distribution of current intensity in the metal grid, thereby facilitating uniform heating.

[0015] For example, in a hot compress device provided in another embodiment of the first aspect of the present disclosure, the metal grid includes second sub-grids arranged in an array into a plurality of rows and columns and spaced apart from each other.

[0016] In this solution, the second sub-grid in a specific area can be energized to achieve heating of the user's eyes and surrounding specific areas.

[0017] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the lens assembly includes a plurality of input wires and output wires, and each second sub-grid connects at least one input wire and at least one output wire, wherein the input wires, output wires and the metal grid are in the same layer and are an integrated structure.

[0018] In this solution, the input wires and the output wires are arranged in the same layer as the second sub-grid, which is conducive to the lightness and thinness of the entire lens assembly.

[0019] For example, in a hot compress device provided in another embodiment of the first aspect of the present disclosure, the lens assembly includes a plurality of input wires and output wires, and each second sub-grid connects at least one input wire and at least one output wire, wherein the lens assembly also includes a dielectric layer, the dielectric layer is located between the input wire and the metal grid and between the output wire and the metal grid, and through holes are provided in the dielectric layer, and the input wire and the output wire are connected to the metal grid through the through holes.

[0020] In this solution, each of the input wires and the output wires is located at a different layer from the second sub-grid, and the setting of the input wires and the output wires will not affect the layout of the second sub-grid. For example, the spacing between adjacent second sub-grids is not limited by the input wires and the output wires and is thus maintained at a relatively small state, thereby making the arrangement density of the second sub-grids high, and when applying hot compress to the user's eyes and specific parts of the surrounding area, the positioning accuracy can be improved.

[0021] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the input wire and the output wire coincide with the grid lines in the metal grid.

[0022] In this solution, when each of the input wire and the output wire is located in a different layer from the second sub-grid, the input wire and the output wire are designed to overlap with the grid lines in the metal grid. From a visual perspective, the uneven distribution of light transmittance of the lens assembly caused by the input wire and the output wire can be avoided, thereby improving the visual effect of the lens assembly.

[0023] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the input wire and the output wire are located on both sides of the metal grid, and the dielectric layer includes a first sub-dielectric layer located between the input wire and the metal grid and a second sub-dielectric layer located between the output wire and the metal grid.

[0024] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the power module includes a power supply, a switch component and a control chip, the switch component is electrically connected between the power supply and the metal grid, and the control chip is signal-connected to the power supply and the switch component.

[0025] For example, a hot compress device provided by an embodiment of the first aspect of the present disclosure further includes an image recognition device. The image recognition device is connected to the control chip signal, and the image recognition device is configured to convert the user action into a data signal and transmit it to the control chip, and the control chip adjusts the switch state of the switch component and / or the output power of the power supply according to the data signal.

[0026] In this solution, the user action can be a non-contact hot compress device or a visual hot compress eye mask including the hot compress device, thereby avoiding shaking caused by touch and improving user experience.

[0027] The second aspect of the present disclosure provides a visualized hot compress eye mask, which includes a frame and the hot compress device in the first aspect. The frame is used to fix the hot compress device. The frame includes a frame and temples, the frame fixes the lens assembly, and the power module is arranged on at least one of the frame and the temples. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In some solutions, hot compress products use chemical reactions, which are irreversible, making them disposable items, which is not conducive to saving and environmental protection; in addition, these hot compress products use chemical reactions of materials to achieve hot compress. In view of this, in other solutions, conductive materials are used for heating. However, none of the above solutions can make the hot compress products visible. When using these hot compress products, users need to stop normal activities and focus on hot compress, which leads to poor applicability of the above hot compress products.

[0040] On the one hand, the present disclosure provides a hot compress device and a hot compress eye mask, which can solve the above-mentioned technical problems. The hot compress device can be applied to a visualized hot compress eye mask. The hot compress device includes a lens assembly and a power module, the lens assembly includes a transparent conductive film and a transparent substrate for fixing the transparent conductive film, and the power module is electrically connected to the transparent conductive film. The transparent conductive film includes a metal grid. After the power module is used to energize the metal grid, the metal grid can emit thermal radiation, thereby achieving hot compress; in addition, the metal grid can be light-transmissive, so that the hot compress eye mask with the hot compress device has a visual function, and during the hot compress process, the user can carry out daily life or work and other activities.

[0041] Below, the specific structure of the hot compress device and the hot compress eye mask in at least one embodiment of the present disclosure is described in conjunction with the accompanying drawings.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, at least one embodiment of the present disclosure provides a hot compress eye mask comprising a hot compress device ( Figure 1 Only the lens assembly 100 included in the hot compress device is presented, the hot compress device includes the lens assembly 100 and a power module (see the power supply, switch assembly, control chip, etc. in the following embodiments), the lens assembly 100 includes a substrate 110 and a transparent conductive film, and the transparent conductive film includes a metal grid 120. The transparent conductive film 200 is disposed on the surface of at least one side of the lens 100, and the transparent conductive film 200 includes a metal grid 210.

[0043] For example, in the hot compress device provided in at least one embodiment of the present disclosure, the metal grid is made of an opaque metal material. Metal materials with strong electrical and thermal conductivity (such as metal elements or alloys) are usually opaque. By using the metal grid design in the aforementioned embodiment, the transparent conductive film can be visually transparent. Therefore, the scheme of setting a metal grid in the hot compress device will not adversely affect the visibility of the hot compress device.

[0044] For example, in the hot compress device provided in at least one embodiment of the present disclosure, the metal material includes silver, copper, aluminum, molybdenum, titanium, nickel, etc.

[0045] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the metal grid includes a plurality of meshes, and the plurality of meshes are evenly arranged in a plurality of rows and columns. The metal grid can be composed of metal wires, and the metal wires surround the meshes. The metal wires are opaque. When the meshes are evenly arranged, the light transmittance of the metal grid (lens assembly) is uniform in visual effect, and the uneven light transmittance will not cause adverse effects on the user's vision.

[0046] For example, in the hot compress device provided in at least one embodiment of the present disclosure, the thickness of the metal grid can be 50 to 500 microns, the line width of the metal wire is 1 to 10 microns, further 1 to 5 microns, and the equivalent aperture of the mesh is 50 to 500 microns, further 100 to 500 microns. For example, the line width of the metal wire is further 2, 3, 4, 6, 8 microns, etc., for example, the line width can be 4 to 10 microns or 2 to 3 microns. The metal grid with the above parameters can ensure good thermal radiation while not adversely affecting the visibility of the lens assembly in terms of visual effects that can be distinguished by the human eye.

[0047] In the embodiments of the present disclosure, there is no restriction on the shape of the mesh of the metal mesh, and it can be designed according to the actual process requirements. For example, the shape of the mesh can be as follows: Figure 3 The rectangle shown (eg, square) may be a regular or irregular shape such as a triangle, a polygon, or a circle.

[0048] It should be noted that in the embodiments of the present disclosure, there is no limitation on the type of substrate and the number, position distribution and manner of the transparent conductive film (metal grid) disposed on the substrate. For example, the substrate may be a myopia, hyperopia or other type of lens.

[0049] For example, in the hot compress device provided in some embodiments of the present disclosure, the transparent conductive film is located on the surface of the substrate. Figure 2As shown, the metal grid 120 of the transparent conductive film is arranged on one side of the substrate 110 (for example, the side of the lens facing the human eye or away from the human eye). For example, the metal grid 120 can be directly prepared on the substrate 110 by chemical vapor deposition, magnetron sputtering, photolithography, etc., so that the metal grid 120 can be prevented from falling off from the substrate 110, and it is conducive to a lightweight design; or, the transparent conductive film including the metal grid 120 can be attached to the substrate 110 by a glue layer, so that the preparation process is convenient and the cost is low.

[0050] For example, in some other embodiments of the present disclosure, the substrate includes a first substrate and a second substrate, and the transparent conductive film is sandwiched between the first substrate and the second substrate. Figure 4 As shown, the substrate includes a first substrate 111 and a second substrate 112, and the metal grid 120 is located between the first substrate 111 and the second substrate 112. When the hot compress device and the hot compress eye mask are used, the first substrate 111 and the second substrate 112 can act as a protective layer to protect the metal grid 120.

[0051] For example, when the hot compress device and the hot compress eye mask are used, the first substrate faces the human eye, that is, the first substrate is located on the inner side of the lens assembly, and the second substrate faces away from the human eye, that is, the second substrate is located on the outer side of the lens assembly. Figure 4 As shown, the thickness of the first substrate 111 may be less than the thickness of the second substrate 112. In this way, the first substrate 111 is thinner than the second substrate 112, so that the heat radiation generated by the metal grid 120 is more likely to pass through the first substrate 111 and is more likely to be blocked by the second substrate 112, so that the heat radiation generated by the metal grid 120 can be used for hot compress as much as possible.

[0052] In the embodiments of the present disclosure, there is no limitation on the planar shape of the metal grid, and it can be designed according to the actual process requirements.

[0053] For example, in some embodiments of the present disclosure, the metal grid may be a grid structure that is integrated throughout the entire surface. Figure 3 As shown. Figure 3 In the metal grid 120 shown, each metal wire used to define the mesh can be regarded as a resistor. In this way, when a voltage is applied across the metal grid 120, the current can connect the two ends via several paths, but the number of resistors in different paths (which can also be regarded as the path length) may be different. In this way, when power is turned on, the power (heating efficiency) of different areas of the metal grid is different, and the problem of uneven heating still exists to a certain extent.

[0054] For example, in some other embodiments of the present disclosure, the metal grid includes a plurality of first subgrids arranged side by side and spaced apart from each other. In this way, since the subgrids are spaced apart from each other, when the metal grid is powered on, the current flowing into any subgrid will not flow into other subgrids. Compared with the grid structure with the entire surface integrated, it is beneficial for the current intensity to be evenly distributed in the metal grid, thereby facilitating uniform heating. For example, Figure 5 As shown, the metal grid includes first subgrids 121a, 121b and 121c arranged in parallel, and the first subgrids 121a, 121b and 121c are spaced apart from each other. Figure 3 In comparison, it is equivalent to reducing the difference in the number of resistors (path lengths) in different current paths, which is conducive to uniform heating of the metal grid.

[0055] For example, in Figure 5 In the manufacturing process of the metal grid shown in FIG. 1 , a metal grid can be prepared as follows: Figure 3 The metal grid shown in the figure then disconnects the metal wires of the metal grid along the area where the preset sub-grids are located and along the boundary between adjacent sub-grids. In this way, the uniformity of the distribution of the metal wires of the entire metal grid can be ensured, which is conducive to uniform light output.

[0056] For example, in some other embodiments of the present disclosure, the metal grid includes second subgrids arranged in a plurality of rows and columns and spaced from each other. In this way, the second subgrids in a specific area can be electrified to achieve heating of the user's eyes and surrounding specific areas. Figure 6 As shown, the metal grid includes second subgrids 122a, 122b and 122c, which are arranged in a row but in different columns, and the second subgrids 122a, 122b and 122c arranged in multiple rows can form an array structure. In this way, a single second subgrid 122a can be electrified, while the other second subgrids 122b and 122c are not electrified, so that a specific area corresponding to the second subgrid 122a (such as the corner of the eye, the eye socket, the eyeball, or a specific acupuncture point in and around the eye) can be heated.

[0057] In the embodiment of the present disclosure, when the metal grid is divided into a plurality of second sub-grids arranged in an array, each second sub-grid needs to be energized separately. In the case of pursuing a higher hot compress accuracy, the plane design area of ​​the second sub-grid can be increased and reduced and the setting density of the second sub-grid can be increased. Accordingly, the number of wires used to energize the second sub-grids increases, and their arrangement needs to be designed.

[0058] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the lens assembly includes a plurality of input wires and output wires, each second sub-grid is connected to at least one input wire and at least one output wire, wherein the input wires, the output wires and the metal grid are in the same layer and are an integrated structure. In this way, the input wires and the output wires are arranged in the same layer as the second sub-grid, which is conducive to the thinning of the entire lens assembly. For example, Figure 6 As shown, the second sub-grid 122a is connected to the input wire 131a and the output wire 132a. For example, in the process of forming the metal grid and the input wire 131a and the output wire 132a, the second sub-grid 122a can be formed first. Figure 3 The metal mesh of the structure shown is then cut off to form Figure 6 The input wire 131a and the output wire 132a are shown. Thus, the input wire 131a, the output wire 132a and the metal grid are in the same layer, and the macroscopic visual effect is still maintained. Figure 3 The layout of the metal grid shown makes the light transmittance of the lens assembly uniform, which helps to improve the user experience.

[0059] For example, in the hot compress device provided in other embodiments of the present disclosure, the lens assembly includes a plurality of input wires and output wires, each second sub-grid is connected to at least one input wire and at least one output wire, wherein the lens assembly also includes a dielectric layer, the dielectric layer is located between the input wire and the metal grid and between the output wire and the metal grid, a through hole is provided in the dielectric layer, and the input wire and the output wire are connected to the metal grid through the through hole. In this way, each of the input wire and the output wire is located in a different layer from the second sub-grid, and the setting of the input wire and the output wire will not affect the layout of the second sub-grid. For example, the spacing between adjacent second sub-grids is not limited by the input wire and the output wire and is kept in a relatively small state, so that the arrangement density of the second sub-grid is high, and when performing hot compress on the user's eyes and specific parts of the surrounding area, the positioning accuracy can be improved.

[0060] For example, Figure 7 and Figure 8 As shown, the input wire 131b, the output wire 132b and the metal grid 120 ( Figure 7It is shown that the second sub-grids 122a to 122c included in the metal grid 120 are located in different layers. The input wire 131b, the output wire 132b and the metal grid 120 are separated by a dielectric layer 140. For example, in the preparation process of the lens assembly, after the metal grid 120 is formed, the dielectric layer 140 is deposited on the metal grid 120; then a through hole is formed in the dielectric layer 140; then a conductive material film is deposited on the dielectric layer 140, and the conductive material film is connected to the metal grid 120 through the through hole; then the conductive material film is subjected to a composition process (such as photolithography) to form the input wire 131b and the output wire 132b. It should be noted that the above process sequence can be adjusted according to actual process requirements. For example, the input wire 131b and the output wire 132b can be prepared first, and then the dielectric layer 140 and the metal grid 120 are formed in sequence.

[0061] For example, the lens assembly may further include a flat layer, the flat layer covers the input wire and the output wire, or the flat layer covers the metal grid. Figure 8 As shown, after forming the input wire 131b and the output wire 132b, a planarization layer 150 is deposited to achieve surface planarization. Figure 4 When the second substrate 112 is formed, a uniform thickness can be ensured.

[0062] For example, in a hot compress device provided by an embodiment of the first aspect of the present disclosure, the input wire and the output wire overlap with the grid lines in the metal grid, that is, the orthographic projection of the portion of the input wire and the output wire that overlaps with the metal grid (including metal wires and meshes) on the substrate overlaps with the orthographic projection of a portion of the metal wires (grid lines) of the metal grid on the substrate. In this way, when each of the input wire and the output wire is located at a different layer from the second sub-grid, the input wire and the output wire are designed to overlap with the grid lines in the metal grid. From a visual effect perspective, the phenomenon of uneven light transmittance distribution of the lens assembly caused by the input wire and the output wire can be avoided, thereby improving the visual effect of the lens assembly.

[0063] For example, in the hot compress device provided in some embodiments of the present disclosure, the input wire and the output wire are located on the same side of the metal grid, which is conducive to the lightweight design of the lens assembly, and the manufacturing process of the lens assembly is less, which is conducive to reducing costs. The structure of the lens assembly with this structure can be seen in Figure 8 .

[0064] For example, in some other embodiments of the present disclosure, the input wire and the output wire are located on both sides of the metal grid, and the dielectric layer includes a first sub-dielectric layer located between the input wire and the metal grid and a second sub-dielectric layer located between the output wire and the metal grid. Fig. 9As shown, the input wire 131b and the output wire 132b are respectively located on both sides of the metal grid. A first sub-dielectric layer 140a is provided between the input wire 131b and the metal grid 120, and a through hole is provided in the first sub-dielectric layer 140a, and the input wire 131b and the metal grid 120 are connected through the through hole; a second sub-dielectric layer 140b is provided between the output wire 132b and the metal grid 120, and a through hole is provided in the second sub-dielectric layer 140b, and the output wire 132b and the metal grid 120 are connected through the through hole.

[0065] For example, in some other embodiments of the present disclosure, the hot compress device provided by Fig. 9 As shown, the planar layer of the lens assembly may further include a first sub-planar layer 150a and a second sub-planar layer 150b, wherein the first sub-planar layer 150a covers the input wire 131b, and the second sub-planar layer 150b covers the output wire 132b.

[0066] For example, in the embodiment of the present disclosure, the materials of the dielectric layer and the planar layer may be silicon nitride, silicon oxide, silicon oxynitride, etc.

[0067] For example, in the hot compress device provided in at least one embodiment of the present disclosure, the power module includes a power supply, a switch component and a control chip, the switch component is electrically connected between the power supply and the metal grid, and the control chip is signal-connected to the power supply and the switch component. Fig.10 As shown, the switch assembly 300 controls the power supply 20 to the transparent conductive film layer (shown therein the metal grid 120), and the control chip 400 controls the switching function of the switch assembly 300. In this way, the control chip 400 can select whether to supply power to the metal grid 120 to achieve heating.

[0068] For example, the control chip can be a central processing unit, a digital signal processor, a single-chip microcomputer, a programmable logic controller, etc. For example, the control chip can also include a memory, a power module, etc., and realize the power supply and signal input and output functions through additionally provided wires, signal lines, etc. For example, the control chip can also include hardware circuits and computer executable codes, etc. The hardware circuit can include conventional very large scale integration (VLSI) circuits or gate arrays and existing semiconductors or other discrete components such as logic chips and transistors; the hardware circuit can also include field programmable gate arrays, programmable array logic, programmable logic devices, etc.

[0069] For example, in an embodiment of the present disclosure, the switch assembly 300 may be disposed on a circuit board, one end of at least one of the input wire and the output wire is connected to the metal grid, and the other end thereof is used as a terminal (e.g. Figure 7 and Figure 8The input terminal D1 and the output terminal D2 shown in the figure are connected to the circuit board. For example, the switch included in the switch assembly can be a transistor or other types of switch elements. For example, these transistors are integrated on the circuit board, and each input wire and / or output wire is controlled by the transistor to be turned on or off, thereby realizing the control of the switching state of the heating function of the metal grid or the sub-grid included in the metal grid.

[0070] For example, at least one embodiment of the present disclosure provides a hot compress device that further includes an image recognition device. Fig.10 As shown, the image recognition device 500 is connected to the control chip 400 by signal, and the image recognition device 500 is configured to convert the user action into a data signal and transmit it to the control chip 400, and the control chip 400 adjusts the switch state of the switch component 300 and / or the output power of the power supply 200 according to the data signal. In this way, the user action can be a non-touch hot compress device or a visual hot compress eye mask including the hot compress device, thereby avoiding shaking caused by touch and improving the user experience.

[0071] For example, the image recognition device may include a gesture sticker and / or a first sensor, and the first sensor may be an image sensor. The hot compress component may pre-store gesture shapes or motion trajectories corresponding to specific instructions, and the gesture sticker and / or the image sensor may be used to detect the shape and / or motion trajectory of the user's gesture. After the user makes a gesture shape and / or motion trajectory corresponding to the instruction, the control chip may control the switch of the metal grid or the switch of the sub-grid of a specific area of ​​the metal grid according to the corresponding instruction, and may also control the output power of the power supply to adjust the temperature.

[0072] For example, the image recognition device may include a second sensor that can detect the user's blinking frequency. In this way, the user can send instructions to the control chip through a specific blinking frequency, so that the metal grid can be turned on and off or the sub-grids in a specific area of ​​the metal grid can be turned on and off according to the corresponding instructions, and the output power of the power supply can be controlled to adjust the temperature. In this way, the user's hands can be completely freed and the operation is convenient.

[0073] For example, in at least one embodiment of the present disclosure, the hot compress device may further include a temperature sensor, which is connected to the control chip signal. The temperature sensor can be used to monitor the temperature in real time, so as to regulate the temperature. For example, the hot compress device can be selected (for example, the user selects it when using it) to be set within the range of a first preset temperature and a second preset temperature, and the first preset temperature is less than the second preset temperature. When heating starts, if the heating temperature of the hot compress device reaches the second preset temperature, the temperature sensor detects the temperature and sends an instruction to the control chip, and the control chip adjusts the output power of the power supply, for example, so that the output power presents a sinusoidal periodic change, so that the temperature is maintained between the first preset temperature and the second preset temperature to prevent the temperature from being too high or too low.

[0074] For example, the second preset temperature may be 50 degrees Celsius or other suitable temperature values. For example, the difference between the first preset temperature and the second preset temperature may be less than 2 degrees Celsius, for example, further less than 1 degree Celsius.

[0075] At least one embodiment of the present disclosure provides a visual hot compress eye mask, which includes a frame and the hot compress device in the above aspect. The frame is used to fix the hot compress device. The frame includes a frame and temples, the frame fixes the lens assembly, and the power module is arranged on at least one of the frame and the temples. For example, Figure 1 As shown, the frame 10 is used to fix the lens assembly 100, and the temple 20 is connected to the frame 10 (for example, a detachable connection). The power module in the hot compress eye mask is arranged on the frame, and the power supply 200 can be arranged in the temple 20 to prevent the power supply 200 from being exposed to the outside and destroying the appearance of the entire hot compress eye mask. For example, further, the power supply 200 and the control chip 400 can be arranged at one end of the temple 20 away from the frame 10. For example, further, the wires for connecting the transparent conductive film (metal grid), the power supply, the switch assembly and the control chip can be arranged inside the frame and the temple, so that the above design does not affect the appearance of the entire hot compress eye mask. For example, the wire can be covered with an insulating outer skin, such as plastic, silicone, etc. For example, the image recognition device 500 can be arranged on the frame or the temple.

[0076] For example, in some other embodiments of the present disclosure, the wires, power supply, switch assembly and control chip can be designed as an integrated structure covered with an insulating outer shell, and the integrated structure can be attached to or wrapped on the temples of the eye mask to be electrically connected to the transparent conductive film on the lens assembly.

[0077] For example, the frame may include structures such as an upper cover bracket and a nose pad. The upper cover bracket may be made of an aluminum alloy, which may be processed by sandblasting, surface brushing, etc., and may be provided with a silver appearance. The nose pad may be made of silicone, which may be processed by hot pressing, etc., and may be provided with an off-white appearance.

[0078] For example, the material of the base material of the lens assembly can be a material with high light transmittance such as glass or resin.

[0079] For example, the equivalent diameter of the middle part of the temple is smaller than the equivalent diameter of the two end parts, so as to present a simpler appearance. For example, the equivalent diameter of the middle part of the temple can be set within 5mm, such as 1.5mm, 2.5mm, 3.5mm, 4.5mm, etc.; the end of the temple away from the frame can be used to accommodate a power source, and its equivalent diameter can be set to be greater than 5mm. When the user wears it, this part is hidden behind the ear, which can not only ensure that the eye mask has a more beautiful viewing angle effect, but also increase the weight of the end of the temple away from the frame to prevent the eye mask from slipping when worn.

[0080] For example, in an embodiment of the present disclosure, the edge portions of the frame and the temples (such as the portions where the frame and the temples are connected) are chamfered to reduce the risk of scratches on the frame and the temples due to sharpness, and to provide a better visual effect.

[0081] For example, the hot compress eye mask can be set as follows Figure 1 The jack 30 shown is used to charge and discharge the power supply or to connect other devices.

[0082] For example, in at least one embodiment of the present disclosure, the hot compress eye mask may further include a mask body, so that the lens assembly of the hot compress eye mask and the human face form a closed chamber to maintain the temperature in the closed chamber.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
