[0004] This application claims priority to Chinese Patent Application No. 202520467473.6, filed on March 14, 2025, entitled "A Water Absorbent Mesh Fabric and Humidifying Device", the entire contents of which are incorporated herein by reference. Technical Field

[0005] This application relates to the field of household appliance technology, and more particularly to a humidifier, and a fiber mesh, fabric, and water-absorbing component used in the humidifier. Background Technology

[0006] Current evaporative humidifiers typically include a water tank, a water pump, a wick filter, and a fan. The water pump draws water from the tank to wet the filter, and the airflow generated by the fan passes through the filter, causing the water on the filter to evaporate and be blown out with the airflow, thus humidifying the air. The filter can be made of mesh fabric, which also serves to store water.

[0007] The mesh fabric in the related technology includes a first surface layer, a second surface layer, and connecting fibers. Multiple ventilation openings are provided on the first and second surface layers to form a three-dimensional ventilation channel for the passage of moisture-laden airflow. The connecting fibers are relatively densely and curvedly connected between the first and second surface layers. The gaps between the connecting fibers allow for water absorption and storage through capillary action.

[0008] However, since the connecting fibers are inherently curved, prolonged moisture and airflow can further exacerbate this curvature, weakening the mesh's elastic recovery. Furthermore, the curved connecting fibers gradually embed themselves into the ventilation openings on the first and second layers, blocking the three-dimensional ventilation channels and reducing the effective ventilation area. This not only significantly increases the mesh's ventilation resistance but also easily creates tiny water films inside the three-dimensional ventilation channels or at the openings, thereby reducing airflow efficiency and overall humidification performance.

[0009] To improve the water storage capacity of related technical mesh fabrics, attempts have been made to increase the opening area, aiming to increase airflow within the pore structure and reduce water film formation. However, due to the curved design of the connecting fibers, the stiffness is relatively low. As the opening area increases, the overall stiffness and rigidity of the mesh fabric decrease, its resilience deteriorates, and misalignment between openings can easily occur, further reducing airflow within the pore structure and thus failing to effectively increase the water storage capacity of the mesh fabric.

[0010] Furthermore, with the increased wind resistance of the mesh fabric, in order to overcome the higher wind pressure loss when the mesh fabric is wet, the humidification device needs to be configured with a higher wind speed to achieve a better humidification effect, which will reduce the energy efficiency ratio of the humidification device.

Detailed Implementation

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] As shown in Figures 1 to 3, a first aspect of this application provides a fiber mesh 100. This fiber mesh 100 can be used to manufacture a fabric 200. The fabric 200 can be applied to a humidifier 2000 and used as a wick filter in the humidifier 2000. When the airflow disturbed by the air supply device 2100 within the humidifier 2000 blows across the moist fabric 200, the moisture on the fabric 200 flows with the airflow into the indoor environment, thereby increasing the air humidity in the indoor environment.

[0062] The fiber mesh 100 includes at least two base layers stacked at intervals, each base layer having multiple openings. In some embodiments, the fiber mesh 100 includes two base layers. For ease of description, the two base layers are referred to as a first base layer 10 and a second base layer 20, as shown in FIG1. ​​The first base layer 10 and the second base layer 20 are spaced apart, and the direction in which the first base layer 10 and the second base layer 20 are spaced apart is a first direction, or it can be understood as the first base layer 10 and the second base layer 20 being spaced apart along a first direction.

[0063] In another embodiment, the fiber mesh 100 includes two or more base layers, such as three base layers stacked at intervals, or four base layers stacked at intervals, as shown in Figure 11. The structures of the two or more base layers can be the same or different. The base layers can be stacked at equal or unequal intervals. Preferably, the distance between the base layers is between 2 mm and 5 mm, that is, the length of the connecting fibers between the base layers is between 2 mm and 5 mm. When the fiber mesh 100 includes an even number of base layers stacked at intervals, these base layers can first be connected in pairs by connecting fibers to form mesh units as shown in Figure 1, and then two or more mesh units can be connected by connecting fibers to obtain the fiber mesh 100 including four or more base layers as shown in Figure 4.

[0064] When the fiber mesh 100 is laid flat, that is, when the first base layer 10 and the second base layer 20 are unfolded, the first direction can be perpendicular or approximately perpendicular to the plane where the first base layer 10 or the second base layer 20 is located.

[0065] The first base layer 10 can be a fabric woven from yarn. Multiple first openings 11 can be provided on the first base layer 10. The first openings 11 are used for airflow. The edge contour of the first opening 11 is a structure woven from yarn. Adjacent first openings 11 can share a portion of their edge contour.

[0066] The second base layer 20 can be a woven fabric. Multiple second openings 21 can be provided on the second base layer 20. The second openings 21 are used for airflow. The interior of the second opening 21 is hollow, and the edge contour of the second opening 21 is a woven structure. Adjacent second openings 21 can share a portion of their edge contour.

[0067] As shown in Figures 2 and 3, the first opening 11 and the second opening 21 are correspondingly arranged along the first direction. That is, the projections of the first opening 11 and the second opening 21 onto the first direction can overlap or approximately overlap. The corresponding arrangement of the first opening 11 and the second opening 21, combined with the spacing of the first base layer 10 and the second base layer 20 along the first direction, can be understood as forming a perforated structure for ventilation between the first opening 11 and the second opening 21.

[0068] It is understandable that the first opening 11 and the second opening 21 are set in a corresponding manner, so that the ventilation area of ​​the hole structure can be maximized without changing the shape and size of the first opening 11 and the second opening 21, thereby reducing the wind resistance of the fiber mesh 100 when it is wet.

[0069] Connecting fibers 30 are connected between the outlines of the first opening 11 and the corresponding second opening 21. Each pair of first openings 11 and second openings 21 is connected by connecting fibers 30, thereby achieving the connection between the first base layer 10 and the second base layer 20.

[0070] The hydrophilicity of the first base layer 10 and the second base layer 20 is greater than that of the connecting fiber 30. Hydrophilicity refers to the water retention or absorption capacity of a fiber or yarn. Hydrophilicity can be quantified by the contact angle formed by a water droplet on a material surface. That is, for the fiber mesh 100 of this embodiment, the first base layer 10 and the second base layer 20 achieve water absorption and storage, rather than relying on the connecting fiber 30 for water absorption and storage. The connecting fiber 30 connects the first base layer 10 and the second base layer 20 and provides support between them, thereby maintaining a stable structural shape for the fiber mesh 100.

[0071] As shown in Figure 3, the first opening 11 is projected along the first direction to form an opening projection area. The second opening 21 is also projected along the first direction to form an opening projection area. That is, the first opening 11 and the second opening 21 are projected in a direction perpendicular to the first base layer 10 and the second base layer 20. The projection of the first opening 11 and the projection of the second opening 21 have the same or approximately the same shape. Preferably, the projections formed by the first opening 11 and the second opening 21 coincide with or approximately coincide with region A.

[0072] It is particularly important to note that in this embodiment, the projection of the connecting fiber 30 along the first direction is outside the projection area A of the opening. That is, as shown in FIG3, the connecting fiber 30 does not extend into the perforated structure between the first opening 11 and the second opening 21. When viewed from the first direction, or when the fiber mesh 100 is observed from above the first base layer 10 or the second base layer 20, the connecting fiber 30 is not observed from the first opening 11 or the second opening 21. Since the fiber mesh 100 does not rely on the connecting fiber 30 as a water-absorbing fiber, and the connecting fiber 30 does not extend into the perforated structure between the first opening 11 and the second opening 21, the perforated structure has sufficient airflow. When the airflow blows across the moist fiber mesh 100, the airflow has a larger gas-liquid contact area with the first base layer 10 and the second base layer 20, and a smaller contact area with the connecting fiber 30. The moisture in the fiber mesh 100 will be more easily vaporized, resulting in a larger humidification capacity.

[0073] In related technologies, the connecting fibers 30 in the mesh fabric are bent, which makes it impossible to maintain the stiffness of the connecting fibers 30 in the vertical direction. However, in the fiber mesh fabric 100 of this application embodiment, the connecting fibers 30 do not primarily bear the function of water absorption and storage, and therefore do not need to extend into the perforated structure between the first opening 11 and the second opening 21 to contact the airflow. In addition, the connecting fibers 30 themselves have a certain degree of stiffness, so they can be connected almost vertically between the first base layer 10 and the second base layer 20, further improving the deformation resistance of the fiber mesh fabric 100.

[0074] It should be noted that since the connecting fiber 30 does not need to extend into the perforated structure between the first opening 11 and the second opening 21, it does not block the first opening 11, the second opening 21, or the perforated structure. Therefore, the space within the perforated structure can be minimized by the connecting fiber 30, thereby reducing the likelihood of forming a tiny water film and allowing the fiber mesh 100 to have suitable ventilation. The humidifier 2000 using the fiber mesh 100 does not need to be configured with a higher air velocity, thus improving the energy efficiency ratio of the humidifier 2000. It is understandable that if a large number of tiny water films are formed on the mesh, the ventilation resistance of the mesh will increase dramatically, the ventilation capacity of the mesh will decrease, and the humidification performance of the mesh will decrease accordingly, resulting in a lower energy efficiency ratio for the humidifier using the mesh.

[0075] The fiber mesh 100 provided in this embodiment reduces ventilation resistance and avoids the formation of water film at the first opening 11, the second opening 22, and the pore structure because the connecting fibers 30 do not bend and extend into the pore structure. This not only makes the structure of the first base layer 10 and the second base layer 20 more compact, giving the fiber mesh 100 better resistance to deformation, but also further increases the fiber density of the first base layer 10 and the second base layer 20, further improving the water storage performance of the fiber mesh 100.

[0076] Thus, in the fiber mesh fabric 100 provided in this embodiment, the first base layer 10 and the second base layer 20 serve as absorbent and water-retaining fabrics, and the connecting fiber 30 is used to connect the first base layer 10 and the second base layer 20. Since the fiber mesh fabric 100 does not rely on the connecting fiber 30 for water storage, the connecting fiber 30 does not need to bend and extend into the pore structure formed between the first opening 11 and the second opening 21. On the one hand, the connecting fiber 30 has sufficient stiffness, giving the fiber mesh fabric 100 good resistance to deformation. On the other hand, it also reduces the risk of small water films easily generated due to the bending of the connecting fiber 30, giving the fiber mesh fabric 100 suitable wind resistance. Furthermore, it allows the fiber density of the first base layer 10 and the second base layer 20 to be within a suitable range, thereby improving the overall water storage and hydrophilic properties of the fiber mesh fabric 100.

[0077] In some embodiments, as shown in FIG4, the projection of the connecting fiber 30 in the first direction lies on the outline of the first opening 11 and the second opening 21.

[0078] As described above, the first opening 11 and the second opening 21 are hollow, ring-like structures woven from yarn, meaning that the outlines of the first opening 11 and the second opening 21 are woven from yarn. Two adjacent first openings 11 can share at least a portion of their outlines. Two adjacent second openings 21 can also share at least a portion of their outlines. The projection of the connecting fiber 30 into the first direction lies on the outlines of the first opening 11 and the second opening 21. In other words, the connecting fiber 30 does not enter the interior of either of the two adjacent hole structures; that is, the connecting fiber 30 neither blocks the first opening 11 nor the second opening 21, thus minimizing the wind resistance of the fiber mesh 100 in a wet state.

[0079] In some embodiments, as shown in FIG4, the first base layer 10 further includes a plurality of first connecting portions 110. A first connecting portion 110 can be understood as a tiny connecting unit woven from yarn, and the first base layer 10 is equivalent to being woven from a plurality of first connecting portions 110 connected together. The plurality of first connecting portions 110 connect and enclose the aforementioned first opening 11. That is, the plurality of first connecting portions 110 connect to form the outline of the first opening 11. The projection of the connecting fiber 30 in the first direction lies on the outline of the first opening 11, that is, the projection of the connecting fiber 30 in the first direction lies on or within the first connecting portion 110. The connecting fiber 30 does not extend into the spaces of two adjacent sets of holes, thus improving the ventilation of the fiber mesh 100.

[0080] In some embodiments, as shown in FIG4, the second base layer 20 further includes a plurality of second connecting portions 210. A second connecting portion 210 can be understood as a tiny connecting unit woven from yarn, with the plurality of second connecting portions 210 enclosing the aforementioned second opening 21. The plurality of second connecting portions 210 connect to form the outline of the aforementioned second opening 21. The projection of the connecting fiber 30 in the second direction lies on the outline of the second opening 21, that is, the projection of the connecting fiber 30 in the second direction lies on or within the second connecting portion 210. The connecting fiber 30 does not extend into the spaces of two adjacent sets of holes, thus improving the ventilation of the fiber mesh 100.

[0081] As shown in Figure 4, a first mesh 111 is formed at the connection point of adjacent first connecting portions 110, and the first mesh 111 is used for the connecting fiber 30 to pass through. Similarly, a second mesh 211 is formed at the connection point of adjacent second connecting portions 210, and the second mesh 211 is used for the connecting fiber 30 to pass through. The connecting fiber 30 can pass through a first mesh 111 and extend along a first direction and pass through a second mesh 211, and then pass through the next first mesh 111, thus connecting the first base layer 10 and the second base layer 20 in a cyclical manner.

[0082] In some embodiments, the connecting fiber 30 is divided into a plurality of fiber segments 301. The plurality of fiber segments 301 are connected to form an integral structure, that is, the plurality of fiber segments 301 are connected to form the connecting fiber 30.

[0083] As shown in Figure 2, multiple fiber segments 301 can be located between the first base layer 10 and the second base layer 20. Connecting fibers 30 sequentially pass through a first mesh opening 111 and a corresponding second mesh opening 211. This is equivalent to two fiber segments 301 extending between the first mesh opening 111 and the second mesh opening 211. That is, the connecting fiber 30 passes through a single first mesh opening 111 or second mesh opening 211 only once, thus simplifying the structure of the fiber mesh 100, making it easy to manufacture and reducing costs. Simultaneously, the density of the connecting fibers 30 between the first base layer 10 and the second base layer 20 is low, making it less likely for tiny water films to form between the connecting fibers 30, reducing the possibility of wind resistance caused by a wet fiber mesh.

[0084] In some embodiments, the outline of the first opening 11 includes 8 to 40 first connecting portions 110.

[0085] The number of first connecting portions 110 forming the first opening 11 can be greater than or equal to eight. Eight or more first connecting portions 110 can increase the gas-liquid exchange area when the airflow passes through the first opening 11, thereby improving the overall permeability and water storage capacity of the first base layer 10. However, if the number of first connecting portions 110 forming the first opening 11 is less than eight, the woven first opening 11 may be too sparse, resulting in a reduced gas-liquid exchange area between the airflow and the first opening 11, thus failing to form an effective water storage effect within the first base layer 10.

[0086] The number of first connecting parts 110 forming the first opening 11 can be less than or equal to 40. This allows the first base layer 10 to maintain a certain level of water absorption while also possessing good water storage and air permeability. If the number of first connecting parts 110 forming the first opening 11 is greater than 40, the fiber structure inside the first base layer 10 may become too dense, restricting the penetration and diffusion of moisture. This could cause the first base layer 10 to become too heavy after absorbing water, thereby increasing the wind resistance of the fiber mesh 100 in a wet state.

[0087] In some embodiments, the outline of the second opening 21 includes 8 to 40 second connecting portions 210.

[0088] The reason for configuring the number of second connecting parts 210 on the second opening 21 to be between 8 and 40 is the same as the reason for configuring the number of second connecting parts 210 on the first opening 11 to be between 8 and 40, and will not be repeated here.

[0089] In some embodiments, as shown in FIG5, both the first base layer 10 and the second base layer 20 are woven from yarn 40. The yarn 40 may include multiple first fiber filaments 401, and gaps capable of storing water can be formed between the multiple first fiber filaments 401, thereby improving the water absorption of the first base layer 10 and the second base layer 20.

[0090] In some embodiments, the connecting fiber 30 can be a single fiber filament with a certain stiffness, thereby improving the supporting performance of the connecting fiber 30.

[0091] In this embodiment, the connecting fiber 30 is made of a relatively thick single fiber filament, and the diameter of the connecting fiber 30 can be relatively thicker than that of the first fiber filament 401. The connecting fiber 30 has a certain stiffness to support the first base layer 10 and the second base layer 20. At the same time, since the connecting fiber 30 is made of a single fiber filament, its water absorption is weaker than that of the first base layer 10 and the second base layer 20, thereby reducing the cost of the connecting fiber.

[0092] In some embodiments, as shown in Figure 6, the diameter of the connecting fiber 30 can be D1, where 20 μm ≤ D1 ≤ 100 μm. To measure the diameter D1 of the connecting fiber, 50 fibers were randomly selected from the prepared connecting fiber material as test objects. The selected connecting fibers were laid flat on a glass slide and fixed at both ends with transparent tape to keep them straight. The connecting fibers were imaged using an optical microscope equipped with a measurement module (such as an Olympus BX53 with a magnification of 400x), and multiple positions of each connecting fiber were measured using image analysis software (such as ImageJ). During the measurement process, the ambient temperature was controlled at 20℃ ± 2℃, and the relative humidity was 65% ± 5%. The diameter D1 of the obtained connecting fibers was in the range of 20 μm to 100 μm. The above measurement method was performed in accordance with GB / T 6504 and ISO 11566 standards.

[0093] D1 > 20μm, which can give the connecting fiber 30 sufficient support, so that the connecting fiber 30 forms a stable connection between the first base layer 10 and the second base layer 20, and is not easily broken or deformed by external force.

[0094] D1≤100μm ensures that the connecting fiber 30 is not too thick, and that adjacent connecting fibers 30 are not too close to easily generate a tiny water film, thereby reducing the wind resistance when the airflow passes through the fiber mesh 100.

[0095] In some embodiments, the denier of the yarn 40 is between 30 grams and 300 grams. The number of first filaments 401 in a single yarn 40 ranges from 18 to 500. By limiting the fineness of the yarn 40 and the number of first filaments 401 in the yarn 40, the first base layer 10 and the second base layer 20 woven from the yarn 40 have good water absorption and mechanical properties, and a stable structure.

[0096] Denier (D), also known as denier number, is a way of expressing the fineness of a fiber, referring to the weight (in grams) of 9000 meters of yarn. A higher D number indicates a thicker yarn. Filament number (F) is the number of fibers in each yarn.

[0097] For example, the yarn 40 used in the first base layer 10 and the second base layer 20 can be 150D / 144F polyester. 150D means that 9000 meters of yarn 40 weighs 150 grams. The yarn 40 is composed of 144 fine fibers. Conventional blending processes can be used when manufacturing the yarn 40, and monofilament polyester fibers with cross-shaped or triangular cross-sections can be used, with graphene antibacterial agents embedded.

[0098] For example, the yarn 40 used in the first base layer 10 and the second base layer 20 can be 150D / 96F polyester. 150D means that 9000 meters of yarn 40 weighs 150 grams. The yarn 40 is composed of 96 fine fibers. Conventional blending processes can be used to manufacture the yarn 40, employing monofilament polyester fibers with cross-shaped or triangular cross-sections and embedding graphene antibacterial agents.

[0099] For example, the yarn 40 used in the first base layer 10 and the second base layer 20 can be 300D / 96F polypropylene. 300D means that 9000 meters of yarn 40 weighs 300 grams. The yarn 40 is composed of 96 fine fibers. Conventional blending processes can be used to manufacture the yarn 40, employing monofilament polypropylene fibers with triangular cross-sections and embedding graphene antibacterial agents.

[0100] In order to further improve the water absorption of the first base layer 10 and the second base layer 20, in some embodiments, at least a portion of the surface of the first fiber filament 401 has a water storage tank 402. The water storage tank 402 on the surface of the first fiber filament 401 can store more water, thereby improving the water absorption and water storage capacity of the first base layer 10 and the second base layer 20.

[0101] At least a portion of the surface of the first fiber filament 401 has a water storage tank 402. This can be a situation where a portion of the first fiber filament 401 has a water storage tank 402 while another portion of the first fiber filament 401 does not, or where the surface of all the first fiber filaments 401 has a water storage tank 402.

[0102] In some embodiments, the warp density of the fiber mesh 100 is E1, wherein 16 threads / inch ≤ E1 ≤ 50 threads / inch.

[0103] The warp density of the fiber mesh 100 refers to the density of warp yarns per unit length, measured in ends per inch (EPI). The warp density E1 is measured using the fabric density measurement method specified in ASTM D3775-17. Warp yarns may include first fiber 401 and connecting fiber 30. An E1 ≥ 16 ends per inch ensures a sufficiently dense distribution of warp yarns within the fiber mesh 100, maintaining the stability and stiffness of its overall structure and mitigating the problem of deformation or damage caused by excessively sparse warp yarns.

[0104] While ensuring the structural stability of the fiber mesh 100, an E1 of ≤ 50 yarns / inch also reduces the processing complexity and increased costs associated with excessively high warp density. Furthermore, the moderate warp density reduces the risk of airflow being obstructed by overly dense fibers, thus maintaining good ventilation performance of the fiber mesh 100, allowing air and moisture to pass through it smoothly.

[0105] In some embodiments, the weft density of the fiber mesh 100 is E2, wherein 14 threads / inch ≤ E2 ≤ 45 threads / inch.

[0106] The weft density of the fiber mesh 100 refers to the density of weft yarns per unit length, measured in picks per inch (PPI). The warp density E2 is measured using the fabric density measurement method specified in ASTM D3775-17. Weft yarns may include first fiber 401 and connecting fiber 30. When E2 > 14 picks per inch, the structural support performance of the fiber mesh 100 is improved, preventing excessive stretching or deformation under stress, while also facilitating moisture evaporation and maintaining the softness of the fiber mesh 100.

[0107] With E2≤45 threads / inch, the structural integrity and durability of the fiber mesh 100 are maintained while reducing the increased processing difficulty and cost caused by excessive density.

[0108] In some embodiments, the first opening 11 is a polygon. The second opening 21 is also a polygon. The polygon can be a quadrilateral (e.g., a rectangle, a square) or a hexagon, etc. Among them, the hexagon can be a regular hexagon or a non-regular hexagon.

[0109] It should be noted that since the first opening 11 is woven from yarn 40, when the first opening 11 is a polygonal structure, it refers to an approximate polygonal structure. As shown in Figure 7, this application uses a hexagonal-like first opening 11 as an example for illustration. The second opening 21 is similar to the first opening 11.

[0110] As shown in Figure 9, the first opening 11 and the second opening 21 are constructed as a hexagonal structure, which can improve the overall mechanical properties of the first base layer 10 and the second base layer 20, making them less prone to deformation. Furthermore, due to the presence of the corners, the hexagonal first opening 11 and the second opening 21 are less likely to form tiny water films inside. For ease of explanation, this application uses the hexagonal first opening 11 and the second opening 21 as examples.

[0111] In some embodiments, as shown in FIG7, the long diagonal of the first opening 11 and the second opening 21 is the longest diagonal of the polygon, and the short diagonal of the first opening 11 and the second opening 21 is the shortest diagonal of the polygon.

[0112] Optionally, the length of the long diagonal is L1, where 2mm≤L1≤7mm, and the length of the short diagonal is L2, where 2mm≤L2≤6mm.

[0113] By defining the long and short diagonals of the first opening 11 and the second opening 21, the first opening 11 and the second opening 21 can have suitable opening areas, thereby enabling the fiber mesh 100 to have better humidification and wind resistance.

[0114] If the long diagonal and short diagonal of the first opening 11 and the second opening 21 are too long, for example, L1 > 7mm or L2 > 6mm, the opening area of ​​the first opening 11 and the second opening 21 will also increase accordingly. The structure of the first base layer 10 and the second base layer 20 will become loose, the hardness of the fiber mesh 100 will be difficult to control, and the recovery effect of the fiber mesh 100 after being stretched will also decrease accordingly.

[0115] Conversely, if the long diagonal and short diagonal of the first opening 11 and the second opening 21 are too short, for example, L1 < 2mm or L2 < 2mm, the opening area of ​​the first opening 11 and the second opening 21 will be reduced. Since the smaller the opening, the easier it is to generate a water film, the smaller the first opening 11 and the second opening 21 will easily generate a tiny water film, causing the ventilation pressure loss of the wet fiber mesh 100 to increase sharply.

[0116] Therefore, by limiting the lengths of the long and short diagonals of the first opening 11 and the second opening 21 to a suitable range, the structure of the first base layer 10 and the second base layer 20 can be made compact and have a suitable yarn density 40, thereby giving the fiber mesh 100 good water absorption. It can also reduce the risk of forming a tiny water film at the first opening 11 and the second opening 21, which would reduce the ventilation performance of the fiber mesh 100.

[0117] For example, the length of the long diagonal L1 of the first opening 11 and the second opening 21 can be 5 mm, and the length of the short diagonal L2 can be 3 mm.

[0118] For example, the length of the long diagonal L1 of the first opening 11 and the second opening 21 can be 4.5 mm, and the length of the short diagonal L2 can be 3.5 mm.

[0119] In some embodiments, as shown in Figures 8 and 10, the first opening 11 and the second opening 21 are elliptical. The relatively smooth edges of the ellipse can effectively prevent moisture from accumulating at the first opening 11 and the second opening 21, thereby minimizing the formation of a water film and reducing ventilation pressure loss caused by water film formation.

[0120] Optionally, the length of the major axis of the first opening 11 and the second opening 21 is L3, where 2.5mm≤L3≤9mm, and the length of the minor axis is L4, where 2mm≤L4≤7mm.

[0121] By defining the major and minor axes of the first opening 11 and the second opening 21, the first opening 11 and the second opening 21 can have suitable opening areas, thereby enabling the fiber mesh 100 to have better humidification and wind resistance.

[0122] If the major and minor axes of the first opening 11 and the second opening 21 are too long, for example, L3 > 9 mm or L4 > 7 mm, the opening area of ​​the first opening 11 and the second opening 21 will also increase accordingly. The structure of the first base layer 10 and the second base layer 20 will become loose, the hardness of the fiber mesh 100 will be difficult to control, and the recovery effect of the fiber mesh 100 after being stretched will also decrease accordingly.

[0123] Conversely, if the major and minor axes of the first opening 11 and the second opening 21 are too short, for example, L3 < 2.5 mm or L4 < 2 mm, the opening area of ​​the first opening 11 and the second opening 21 will be reduced. Since a smaller opening makes it easier to generate a water film, an excessively small first opening 11 and the second opening 21 will easily generate a tiny water film, causing a sharp increase in the ventilation pressure loss of the wet fiber mesh 100.

[0124] Therefore, by limiting the lengths of the major and minor axes of the first opening 11 and the second opening 21 to a suitable range, the structure of the first base layer 10 and the second base layer 20 can be made compact and have a suitable yarn density 40, thereby giving the fiber mesh 100 good water absorption. It can also reduce the risk of forming a tiny water film at the first opening 11 and the second opening 21, which would reduce the ventilation performance of the fiber mesh 100.

[0125] For example, the length of the major axis L3 of the first opening 11 and the second opening 21 can be 6 mm, and the length of the minor axis L4 can be 4 mm.

[0126] For example, the length of the major axis L3 of the first opening 11 and the second opening 21 can be 4.5 mm, and the length of the minor axis L4 can be 3.5 mm.

[0127] In some embodiments, as shown in FIG3, the thickness of the fiber mesh 100 is W1, wherein 1.5mm < W1 < 8mm.

[0128] The fiber mesh 100 provided in this application embodiment does not rely on the connecting fiber 30 for water absorption and storage. Therefore, the length of the connecting fiber 30 along the first direction can be set to be shorter, thereby reducing the overall thickness of the fiber mesh 100. As a result, the overall thickness of the fabric 200 made from the fiber mesh 100 is thinner, making it suitable for a more miniaturized humidification device 2000.

[0129] With a thickness of 1.5mm < W1 < 8mm, the overall thickness of the fiber mesh can be reduced while maintaining its filtration performance and structural stability, making it lighter and thinner.

[0130] For example, the thickness W1 of the fiber mesh 100 can be 2mm, 3mm, 4mm, 5mm, 6mm or 7mm.

[0131] The data in Table 1 are for the water absorption ratio test of the fiber mesh 100. The test objects include the fiber mesh 100 in Embodiments 1 and 2 of this application, and the existing fiber mesh with bent connecting fibers in Comparative Example 1.

[0132] The measurement procedure used in the water absorption ratio test is as follows: Immerse the fiber mesh fabric 100 in water for 5 minutes, remove the water-absorbed fiber mesh fabric 100, hang it for 2 minutes, and then weigh it. Obtain the weight of the water-absorbed fiber mesh fabric 100 (i.e., the total weight of the fiber mesh fabric 100 and the absorbed water). Water absorption ratio = (weight of fiber mesh fabric 100 after water absorption - weight of fiber mesh fabric 100 before water absorption) / (weight of fiber mesh fabric 100 after water absorption - weight of fiber mesh fabric 100 before water absorption).

[0133] Table 1

[0134] Referring to Table 1, it is illustrated that, under conditions where the shape and size of the openings are similar, the water absorption ratio of the fiber mesh fabric 100 provided in Embodiments 1 and 2 of this application is much greater than that of Comparative Example 1. That is, the water absorption ratio achieved by the fiber mesh fabric 100 provided in this application through the first base layer 10 and the second base layer 20 for water absorption and storage is much higher than that achieved by Comparative Example 1 relying on the connecting fiber 30 for water absorption and storage. The fact that the embodiments of this application do not rely on the connecting fiber 30 for water absorption and storage does not affect the water absorption of the fiber mesh fabric 100; on the contrary, it further improves the water absorption of the fiber mesh fabric 100.

[0135] Meanwhile, when the fiber mesh 100 provided in the embodiments of this application achieves a high water absorption ratio, its thickness is also significantly reduced. For example, in Embodiments 1 and 2, the water absorption ratio of the fiber mesh 100 reaches 3.0 and 3.1, but its thickness is much lower than that of the manufacture 200 in Comparative Example 1.

[0136] The base layer includes at least an original state and a first state. In the first state, the opening has a first opening size. In the original state, the opening has a second opening size. The absolute value of the ratio of the difference between the first opening size and the second opening size to the second opening size is not greater than 10%.

[0137] In the first state, the base layer has a first base layer dimension. In the original state, the base layer has a second base layer dimension. The absolute value of the ratio of the difference between the first base layer dimension and the second base layer dimension to the second base layer dimension is no greater than 10%.

[0138] In use, the fiber mesh 100 can be in various shapes, such as an arc-shaped cylindrical structure as shown in Figures 25-26, or a sheet extending in a plane as shown in Figures 27-28. The fiber mesh 100 can be fixed by a bracket. During use, water is continuously supplied to the fiber mesh 100. The water supply method can be spraying or pouring water onto the fiber mesh 100, or a water tank can be set up, with the bottom part of the fiber mesh 100 immersed in the water, holding the water by suction. Air is propelled by an air-driven device such as a blower 2100, and the air passes through the fiber mesh 100. When the air comes into contact with the base layer and connecting fibers 30 of the fiber mesh 100, the moisture held on the base layer and connecting fibers 30 is dispersed into the air, thereby vaporizing the moisture and carrying it into the external environment through the airflow, achieving humidification. The base layer mainly provides airflow inlets and outlets through openings, thereby reducing air resistance and increasing airflow.

[0139] The original state of the base layer can refer to its state after weaving or production. During the weaving process, due to differences in weaving techniques, equipment, and materials, it is usually impossible for the base layer to precisely conform to the design structure, and uneven structure often occurs, such as uneven distribution of connecting fibers 30. The original state of the base layer can also refer to the state of the fiber mesh 100 after prolonged use, due to aging or shrinkage of the weaving material, causing deformation of the fiber mesh 100, resulting in inward shrinkage, outward expansion, or even bending, thus losing the advantages of its original structure. The first state of the base layer is its state after being subjected to external disturbance. The first state can include an outward stretching state or an inward contraction state. The state of the base layer is not limited to the original state and the first state; in other words, there can be multiple first states. For example, there can be multiple stretching states, such as the user stretching and fixing the base layer to different degrees as needed, allowing the base layer to remain in different stretching states. There can also be multiple contraction states, such as providing different temperatures as needed to cause the base layer to shrink and fix to different degrees, allowing the base layer to remain in different contraction states. The original state and the first state of the base layer are different states manifested by deformation within the extended surface of the base layer, and are different shape states of the base layer. In the same fiber mesh 100, the deformation of the base layer includes multiple base layers with the same or nearly the same deformation. Therefore, the original state and the first state of the base layer can also be said to be the original state and the first state of the fiber mesh 100.

[0140] When the base layer switches between its original state and its first state, the deformation of the opening can take many forms. For example, in the first type of fiber mesh 100, each opening on the base layer has a deformation, and the absolute value of the ratio of the difference between the first opening size and the second opening size to the second opening size is no greater than 10%. The deformation of the opening can be caused by stretching or shrinking. It can be understood that the overall deformation of the base layer in the first type of fiber mesh 100 is not restricted. In the second type of fiber mesh 100, all base layers have deformation, and the absolute value of the ratio of the difference between the first base layer size and the second base layer size to the second base layer size is no greater than 10%. The deformation of the base layer can be caused by stretching or shrinking. The deformation of each opening on the base layer is not restricted. The extension of different openings on the same base layer or on different base layers can be the same or different. The ratio of the difference between the first base layer size and the second base layer size to the second base layer size can be greater than 10%, less than 10%, or less than 5%.

[0141] The first length and the second length, as well as the first base layer size and the second base layer size, can be extensions in a third direction. The third direction can be multiple directions as needed. In the tensile implementation, the base layer is at least used to switch from the original state to the first state under the action of an external force, and the third direction is in the same direction as the external force. Figures 14 and 15 show the structure of the base layer in its original state. The third direction can be the X2 axis direction, as shown in Figure 15. An external force can be applied to the base layer in the X2 axis direction, causing the base layer as a whole and the opening to expand and extend in the X2 axis direction, achieving a larger second length or second base layer size for the opening in the X2 axis direction. The third direction can be the Y2 axis direction, perpendicular to the X2 axis direction, as shown in Figure 16. An external force can be applied to the base layer in the Y2 axis direction, causing the base layer as a whole and the opening to expand and extend in the Y2 axis direction, achieving a larger second length or second base layer size for the opening in the Y2 axis direction. Alternatively, in some other implementations, an external force can be applied to the base layer in an inclined direction relative to the X2 and Y2 axes, causing the base layer as a whole and the opening to expand and extend in the inclined direction. Alternatively, forces can be applied simultaneously in the X2 and Y2 axes, causing the opening to expand in two perpendicular directions at the same time. In the contracted state implementation, the third direction refers to the direction with the greatest opening deformation, which will be described in more detail later with reference to embodiments; or, it refers to the direction with the greatest base layer deformation.

[0142] Setting the absolute value of the difference between the first and second lengths, and the ratio of the first to the second length, to no more than 10%, and setting the absolute value of the ratio of the difference between the first and second base layer dimensions to the second base layer dimension, to no more than 10%, thereby mitigating the negative impacts caused by excessive deformation of the fiber mesh 100. Specifically, in the stretched state, deformation within a range of no more than 10% expands the opening, increasing airflow and the uniformity of the connecting fibers 30 to improve humidification efficiency, and also increasing the ease of installation and cleaning of the fiber mesh 100. Deformation greater than 10% may lead to excessive expansion of the opening in the third direction and excessive compression in the fourth direction perpendicular to the third direction, resulting in a long, narrow opening, obstructing airflow, and potentially causing the connecting fibers 30 to be too far apart, making water film formation difficult. In the contracted state, deformation within a range of no more than 10% allows for a more stable installation of the fiber mesh 100, makes the connecting fibers 30 denser, improves the uniformity of the connecting fibers 30, and increases the water holding capacity of the fiber mesh 100. Deformation exceeding 10% may lead to excessive narrowing of the opening, obstructing airflow, and may cause the connecting fibers 30 to be too close together, resulting in reduced contact area with air. Furthermore, by setting the absolute value of the ratio between the first and second base layer dimensions to the second base layer dimension not to exceed 10%, constraints on openings such as uniformity and shape can be reduced. For example, openings of different shapes can be processed on the base layer, providing different degrees of deformation, ensuring that the overall deformation of the base layer does not exceed 10%.

[0143] It is worth noting that, in order to make the structure more clearly shown in the figures, only a part of the structure is shown in Figures 14-24 of this application, and only a part of the connecting fibers 30 are shown. The remaining connecting fibers 30 can be referred to the partial arrangement shown to form a complete fiber mesh 100.

[0144] The fiber mesh 100 and humidifying device 2000 proposed in this embodiment of the invention mainly achieve smooth airflow through openings in the base layer, thereby increasing air volume. Connecting fibers 30 are attached to the edges of the openings, creating channels between adjacent surface layer openings. The connecting fibers 30 store water, and when air flows between the openings, it comes into contact with the connecting fibers 30, carrying away the moisture on the connecting fibers 30, thus increasing water retention. The base layer can be stretched or contracted from its original state to a first state. On the one hand, stretching changes the shape of the opening, increasing the opening area and airflow. On the other hand, stretching makes the connecting fibers 30 more evenly distributed, improving the reduced effective contact area with air caused by overly dense connecting fibers 30, and allowing for greater water storage between the connecting fibers 30, effectively improving the efficiency of water dispersal into the air. Furthermore, stretching or contracting the opening edges and the relative movement between the connecting fibers 30 loosens the connections of deposits such as scale accumulated on the base layer, making them easier to peel off and facilitating the cleaning of the fiber mesh 100. On the other hand, contraction makes the connecting fibers 30 denser, allowing them to move closer together when they are too sparse or deformed after prolonged use, thus easily forming a water film and increasing water retention. Simultaneously, by ensuring that the absolute value of the ratio of the difference between the first and second lengths is no greater than 10%, the airflow limitation caused by excessively small opening contraction or flattening during stretching is improved, as is the decrease in water retention caused by connecting fibers being too far apart or too close together. Compared to mesh fabrics with fixed opening shapes, it can achieve better humidification effects and is easier to clean and install.

[0145] For ease of description later, a method for forming a base layer is provided below. The base layer can be formed by weaving the connecting parts 1120 together. The weaving method can be that the connecting parts 1120 are wrapped into a ring, and multiple connecting parts 1120 are nested together to form an opening. Alternatively, a single connecting part 1120 can be continuously nested around the ring to form an opening. Alternatively, the connecting parts 1120 can be wrapped into a ring, and multiple connecting parts 1120 can be connected, such as by bonding, to form an opening. It is understood that the connecting parts 1120 are not only used to form a single opening; the adjacent edges of two adjacent openings are formed by the same connecting parts 1120. Alternatively, in some embodiments, the connecting parts 1120 can be shared by more openings, such as three or four openings sharing a portion of the connecting parts 1120.

[0146] The transition of the base layer from its original state to the first state can be outward extension, i.e., the first state includes a stretched state. In the stretched state, the opening has a first opening size equal to a first length along a third direction, while in the original state, the opening has a second opening size equal to a second length along a fourth direction. The first length is greater than the second length. The base layer is used to at least partially transition from the original state to the stretched state under the action of external force.

[0147] The tensile state of the substrate refers to its state after being subjected to an external force and expanding outwards; the entire substrate and its openings will extend outwards. The substrate entering the tensile state under external force can be due to manual stretching by the user. If the external force is removed after stretching, the substrate may automatically spring back to its original state, remain in the stretched state, or only experience a slight springback. Alternatively, the substrate can be held in the stretched state using a support or similar device.

[0148] The transition of the base layer from its original state to the first state can be an inward convergence, meaning the first state includes a contraction state. In the contraction state, the opening has a first opening size equal to a third length along a third direction. In the original state, the opening has a second opening size equal to a fourth length along a third direction, where the third length is less than the fourth length. When the base layer is wetted by water, it at least partially transitions from its original state to the contraction state.

[0149] The shrinkage state of the substrate refers to the state in which the substrate tightens inward after being disturbed by factors such as temperature. The entire substrate and its openings will shrink inward. Temperature disturbances can be changes in air temperature or water temperature. For example, the water temperature supplied to the fiber mesh 100 may be higher than a preset temperature, such as greater than 30 degrees Celsius. This can be achieved by using a spray system, immersing the bottom of the fiber mesh 100 in warm water, or supplying the fiber mesh 100 with water at 30 degrees Celsius, 40 degrees Celsius, 70 degrees Celsius, 80 degrees Celsius, or 100 degrees Celsius. The substrate entering a shrinkage state due to disturbance can be achieved through stable environmental disturbances, such as continuously spraying 40-degree Celsius water onto the substrate, causing it to tighten. Once in a shrinkage state, if the temperature disturbance is removed, the substrate may automatically spring back to its original state, remain in a shrinkage state, or only experience a slight rebound. Alternatively, the substrate can be kept in a shrinkage state by means of external coverings.

[0150] The degree of deformation under tensile and contractile conditions will be further described below.

[0151] Firstly, regarding the stretched state,

[0152] The first and second lengths represent the extension of the opening in a third direction. This expansion in the third direction causes the opening to contract in a fourth direction perpendicular to the third direction. In the stretched state, the opening's first opening dimension also includes a fifth length along the fourth direction. In the original state, the opening's second opening dimension also includes a sixth length along the fourth direction, where the fifth length is less than the sixth length. As shown in Figure 15, when the opening is stretched in the X2 axis direction, it will contract in the Y2 axis direction. And as shown in Figure 16, when the opening is stretched in the Y2 axis direction, it will contract in the X2 axis direction. However, since the connecting part 1120 is elastic, there will be gaps between adjacent connecting parts 1120 during the weaving process. As mentioned above, in the embodiment where the connecting parts 1120 are arranged in a ring shape and the ring-shaped connecting parts 1120 are sleeved, gaps will be generated between the connecting parts 1120. This allows a portion of the stretching amount to be released through the gaps between the connecting parts 1120 and the elasticity of the connecting parts 1120 themselves when stretched in the X-axis direction, reducing the pulling force on the opening in the Y2 direction. Consequently, the inward shrinkage in the Y2 direction will be much smaller than the extension in the X-axis direction, that is, the difference between the sixth length and the fifth length is smaller than the difference between the first length and the second length.

[0153] By switching to the stretched state, the following can be achieved: First, stretching increases the extension of the opening at least in the third direction, while the extension perpendicular to the third direction may decrease. However, since the base layer is fabric, the extension in the third direction can be achieved through the gaps between the loops or the elasticity of the connecting part 1120. Consequently, the decrease in the extension perpendicular to the third direction is usually much smaller than the increase in the extension in the third direction, thus increasing the opening area. This makes it easier for air to pass through the base layer, ensuring sufficient gas flow and reducing the air drive burden. Second, the increased extension of the opening in the third direction makes the shape of the opening more irregular, such as further increasing the ratio of the major axis to the minor axis of the opening. This makes it more difficult for a water film to form on the opening, improving the obstruction of airflow by the water film, ensuring smooth airflow, and reducing noise. Third, since the connecting fiber 30 is connected to the edge of the opening, changes in the shape of the opening will cause the connecting fiber 30 to move. The pulling of the opening edge can adjust the position of the connecting fiber 30. When the opening edge is tighter, the connecting fiber 30 will... A more uniform arrangement of the connecting fibers improves the situation where the connecting fibers 30 are too dense, causing them to abut against each other and reducing the effective contact area with air. It also improves the situation where the connecting fibers 30 are too sparse, making it difficult for them to form a water film effectively, thus reducing the water output of the connecting fibers 30. The uniform arrangement of the connecting fibers 30 can store more water and increase the contact area between the connecting fibers 30 and air, thereby increasing the efficiency of dispersing water into the air. Fourth, since the supply water contains trace amounts of silicon, calcium, magnesium, and other elements, as well as impurities, these trace elements and impurities are prone to deposit in the fiber mesh 100 or its internal gaps, such as the opening edges and between the connecting fibers 30, during long-term use. This forms deposits and scale, which reduces the water absorption effect of the base layer and the connecting fibers 30 and lowers the humidification capacity. When the opening is stretched, the stretching of the opening edges and the relative movement between the connecting fibers 30 loosen the deposits such as scale accumulated on the base layer and the connecting fibers 30, making them easier to peel off and facilitating the cleaning of the fiber mesh 100.

[0154] In one embodiment, the ratio of the difference between the first length and the second length to the second length is greater than or equal to 0.03, which better reflects the many advantages of the aforementioned opening stretching. A ratio less than or equal to 0.1, on the one hand, mitigates the problem of excessive stretching causing the edges of the opening on both sides in the fourth direction to be too close, resulting in the connecting fibers 30 on both sides in the fourth direction being too close together, thereby reducing the formation of a water film between the connecting fibers 30 on both sides in the fourth direction and preventing airflow obstruction. On the other hand, it mitigates the problem of the connecting fibers 30 being too sparse in the third direction, leading to a reduced water film and reduced water holding capacity.

[0155] In one embodiment, the ratio of the difference between the sixth length and the fifth length to the sixth length is greater than or equal to 0.01, providing linkage for the opening to extend upwards in the third direction. This allows for a larger allowable stretching range of the opening in the third direction and enables adjustment of the relative position of the connecting fibers 30 in the fourth direction. A ratio less than or equal to 0.05 mitigates the problem of excessive stretching causing the edges of the opening on both sides in the fourth direction to be too close, resulting in the connecting fibers 30 on both sides of the fourth direction being too close together. This reduces the formation of a water film between the connecting fibers 30 on both sides of the fourth direction, thus preventing airflow obstruction.

[0156] For example, when the difference between the elongation of the base layer in the third direction under tension and the elongation in the third direction under the original state is 0.05, or when the base layer as a whole is stretched by 5% in the X2 axis direction, as shown in Figures 14-15, the ratio of the difference between the sixth length b and the fifth length d to the sixth length b is greater than or equal to 0.01 and less than or equal to 0.05, meaning the deformation in the Y direction of the opening is 1%-5%. As shown in Figure 14, the ratio of the difference between the first length c and the second length a to the second length a is greater than or equal to 0.08 and less than or equal to 0.1, meaning the deformation in the X direction of the opening is 4%-10%.

[0157] The extension of the opening in the third direction can be achieved through various factors. For example, the connecting part 1120 itself has good elasticity, and the connecting part 1120 is used to stretch under the action of external force, so that the base layer switches to a stretched state. If the connecting part 1120 forms a loop, and the loops connect to form an opening, the length of the connecting part 1120 increases through the mutual pulling between the loops, and the circumference of the loop formed by a single connecting part 1120 increases, thereby achieving the extension of the opening. Alternatively, a perforation can be formed between adjacent loops, and the adjacent loops are used to move relative to each other under the action of external force to reduce the perforation and switch the base layer to a stretched state. The perforation is formed between adjacent loops by passing through each other, and one of the adjacent loops will occupy a part of the area within the other loop. The space between two adjacent loops is called a perforation. Or it can be said that the perforation is the area that belongs to two loops at the same time. As shown in Figures 19-22, the adjacent base layers include a first base layer 10 and a second base layer 20. The first base layer 10 includes a plurality of first meshes 111, and the second base layer 20 includes a plurality of second meshes 211. As shown in Figures 19 and 21, the first mesh 111 and the second mesh 211 are holes with a large area. However, after being stretched by an external force in the X2 axis direction, as shown in Figures 20 and 22, the adjacent loops move, which makes the first mesh 111 and the second mesh 211 holes with a smaller area, thereby expanding the opening in the X2 axis direction.

[0158] Secondly, regarding the stretched state,

[0159] The third and fourth lengths represent the contraction of the opening in the third direction, which is the direction of maximum opening deformation and can be any direction. The third direction is related to the shape and arrangement of the opening. As shown in Figure 17-18, the opening contracts more in the X2 direction and less in the Y2 direction, resulting in a larger deformation in the X2 direction, which is the third direction. Alternatively, the opening can be circular, with relatively small differences in deformation in all directions, and the third direction can be any direction. Since the contraction is caused by temperature disturbance, the opening will simultaneously contract in the third direction and in the fourth direction perpendicular to the third direction. In the contracted state, the first opening size of the opening also includes a seventh length along the fourth direction, and in the original state, the second opening size of the opening also includes an eighth length along the fourth direction, where the seventh length is smaller than the eighth length. As shown in Figure 17-18, when the opening contracts in the X2 axis direction, it will simultaneously contract in the Y2 axis direction. By switching to the contraction state, the following can be achieved: First, the opening shrinks in at least two directions due to the contraction. This change in the shape of the opening causes the connecting fibers 30 to move. The pulling of the opening edges can adjust the position of the connecting fibers 30. When the opening edges contract to a more compact position, the loops are squeezed and positioned against each other, making the loop positions more stable and uniform. The connecting fibers 30 will be more evenly distributed, improving the situation where the connecting fibers 30 are too sparse, making it difficult to form a water film between them. The uniform and dense distribution of the connecting fibers 30 can store a larger amount of water and increase the contact area between the connecting fibers 30 and the air, increasing the water content. The efficiency of moisture dispersal from the air; secondly, since the supplied water contains trace amounts of silicon or elements such as calcium and magnesium, and is accompanied by impurities, during long-term use, trace elements and impurities are easily deposited in the fiber mesh 100 or its internal gaps, such as the opening edges and between the connecting fibers 30, forming deposits and scale, which leads to a decrease in the water absorption effect of the base layer and the connecting fibers 30 and a reduction in humidification capacity. When the opening contracts, the contraction of the opening edges and the relative movement between the connecting fibers 30 make the scale and other deposits accumulated on the base layer and the connecting fibers 30 easier to peel off by squeezing and disturbing them, which facilitates the cleaning of the fiber mesh 100.

[0160] In one embodiment, when the immersion water temperature is higher than a preset temperature, the absolute value of the ratio of the difference between the third length and the fourth length to the fourth length is greater than or equal to 0.01. The preset temperature can be room temperature, such as 24 to 30 degrees Celsius, or, in other words, the immersion water temperature is greater than 30 degrees Celsius. An absolute value of the ratio greater than or equal to 0.01 provides sufficient inward shrinkage, enabling better realization of the many advantages of the aforementioned opening shrinkage. An absolute value of the ratio less than or equal to 0.1, on the one hand, improves the situation where excessive inward shrinkage leads to the opening edges being too close together, resulting in the formation of a large amount of water film and obstructing airflow. On the other hand, it improves the problem of the connecting fibers 30 being too dense, causing them to squeeze against each other and reducing the contact area with air.

[0161] The difference between the eighth and seventh lengths may be the same as the difference between the third and fourth lengths, meaning the opening can be recessed to the same degree in all directions. Alternatively, the difference between the eighth and seventh lengths may be less than the difference between the third and fourth lengths. In one embodiment, the absolute value of the ratio of the difference between the eighth and seventh lengths to the eighth length is greater than or equal to 0.02, thereby assisting in the upward recess in the third direction and achieving the many advantages of the aforementioned upward recess in the third direction. The absolute value of the ratio is less than or equal to 0.1, which improves the problem that the edges of the opening on both sides in the fourth direction are too close due to excessive recess, causing the connecting fibers 30 on both sides in the fourth direction to be too close, thereby reducing the formation of a water film between the connecting fibers 30 on both sides in the fourth direction, which would obstruct airflow and reduce the phenomenon of water film formation at the opening.

[0162] As shown in Figures 17-18, the absolute value of the ratio of the difference between the eighth length f and the seventh length h to the eighth length f is greater than or equal to 0.02 and less than or equal to 0.1, meaning the deformation in the Y direction of the opening is 2%-10%. The absolute value of the ratio of the difference between the third length g and the fourth length e to the fourth length e is greater than or equal to 0.01 and less than or equal to 0.1, meaning the deformation in the X direction of the opening is 1%-10%. For ease of explanation, the absolute value of the ratio of the difference between the third length g and the fourth length e to the fourth length e is referred to as the lateral shrinkage ratio, and the absolute value of the ratio of the difference between the eighth length f and the seventh length h to the eighth length f is referred to as the longitudinal shrinkage ratio. For example, when the immersion water temperature is 30 degrees, the lateral shrinkage ratio is 3.5% and the longitudinal shrinkage ratio is 3.1%; when the immersion water temperature is 40 degrees, the lateral shrinkage ratio is 5.0% and the longitudinal shrinkage ratio is 3.8%; when the immersion water temperature is 70 degrees, the lateral shrinkage ratio is 6.4% and the longitudinal shrinkage ratio is 4%.

[0163] The inward contraction of the opening can be achieved through various factors. For example, the connecting part 1120 itself has thermal shrinkage properties; when the temperature rises, the connecting part 1120 contracts, causing the base layer to switch to a contracted state. If the connecting part 1120 forms a loop, and the loops connect to form the opening, the length of the connecting part 1120 decreases, and the circumference of the loop formed by a single connecting part 1120 becomes smaller, thus achieving the inward contraction of the opening. Alternatively, the loops may have thermal expansion properties, forming perforations between adjacent loops. When the loops are heated, they expand, increasing the perforation area and enlarging the perforation, causing the base layer to switch to a contracted state. Perforations are formed between adjacent loops by them passing through each other. One of the adjacent loops occupies a portion of the area within the other loop; the space between two adjacent loops is called a perforation. Alternatively, a perforation can be described as an area belonging to two loops simultaneously. Adjacent base layers include a first base layer 10 and a second base layer 20. The first base layer 10 includes multiple first mesh openings 111, and the second base layer 20 includes multiple second mesh openings 211. The first mesh 111 and the second mesh 211 are small holes. After high-temperature shrinkage, the adjacent loops move, which makes the first mesh 111 and the second mesh 211 larger holes, thereby achieving shrinkage opening and making the connecting fibers 30 denser.

[0164] In one embodiment, the connecting fiber 30 is connected to the perforations of the adjacent base layer to connect the adjacent base layer. This allows the connecting fiber 30 to move due to the stretching and expansion of the base layer or its shrinkage due to heat, thereby making the connecting fiber 30 more evenly distributed. It also makes it easier for the connecting fiber 30 to form a water film, increases the contact area with air, and promotes the shedding of deposits, among other advantages.

[0165] For example, the connecting fiber 30 extends from the first mesh 111 to the second mesh 211, or it can be said that it extends from the second mesh 211 to the first mesh 111. The connecting fibers 30 can be connected in various ways. For instance, a single connecting fiber 30 can be threaded through or through the first mesh 111 to form two connecting fibers 30 extending from the first mesh 111, or the connecting fiber 30 can be threaded through or through the second mesh 211 to form two connecting fibers 30 extending from the second mesh 211. Alternatively, a connecting fiber 30 extending from at least one first mesh 111 can extend into at least two different second meshes 211. As shown in Figures 21-22, the connecting fibers 30 can be connected by sequentially passing through the previous first mesh 111, the previous second mesh 211, the next first mesh 111, and the next second mesh 211, thereby achieving simple weaving and high structural strength. In some other embodiments, at least one connecting fiber 30 extending from the first mesh 111 can also extend into the same second mesh 211. As shown in Figures 19-20, a connecting fiber 30 is wound between the preceding first mesh 111 and the preceding second mesh 211, and another connecting fiber 30 is wound between the following first mesh 111 and the following second mesh 211.

[0166] In the embodiment where the connecting fiber 30 is connected to the first mesh 111 and the second mesh 211, when the opening expands and contracts, and the loops formed by the connecting part 1120 move relative to each other, the connecting fiber 30 can better follow the position of the connecting part 1120 and the trend of opening expansion, thereby achieving adjustment of the position and angle of the connecting fiber 30. In the stretching embodiment, as shown in Figures 19-20, in addition to the surface of the connecting fiber 30, moisture is also retained between the connecting fibers 30, which is called trapped water 300. The trapped water 300 can be in the shape of a water ball as shown in Figure 19, or it can be a water film formed by a large extension area. Impurities 400 are also trapped between the connecting fibers 30. The impurities 400 may be scale deposits or impurities in the water. As shown in Figure 19, because the loops are relatively dense, that is, the first mesh 111 and the second mesh 211 are large, the distance between adjacent connecting fibers 30 is close, and the amount of trapped water 300 formed between the connecting fibers 30 is small, or there may be no trapped water 300. When the loops move relative to each other, the tightening of the first mesh 111 and the second mesh 211 causes the connecting fibers 30 to be moved along with the loops by the first mesh 111 and the second mesh 211, adjusting the position of the connecting fibers 30 as shown in Figure 20. This results in a larger distance between the connecting fibers 30, more water 300 trapped, and easier formation of a large-area water film. Furthermore, as the connecting fibers 30 move further apart, debris 400 trapped between them will be disturbed and dislodged, facilitating cleaning. In Figure 21, because the loops are relatively dense (i.e., the first mesh 111 and the second mesh 211 are large), adjacent connecting fibers 30 are close together, resulting in less water 300 trapped between the connecting fibers, or even none at all. Additionally, the loops are uneven (i.e., the sizes of the multiple first meshes 111 and the multiple second meshes 211 are inconsistent, and there is no clear correspondence between the first meshes 111 and the second meshes 211), leading to irregular angles and spacing of the connecting fibers 30. When the loops move relative to each other, the tightening of the first mesh 111 and the second mesh 211 causes the connecting fibers 30 to be driven by the first mesh 111 and the second mesh 211, causing them to follow the loop's movement. This adjusts the position of the connecting fibers 30 as shown in Figure 22, increasing the distance between them, holding more water 300, and facilitating the formation of a large-area water film. Furthermore, because the circumferences of the loops are relatively similar, the first mesh 111 and the second mesh 211 are evenly distributed, resulting in a more regular arrangement of the connecting fibers 30. This makes water film formation easier and mitigates the problem of reduced water-holding area and air contact area caused by dense contact between the connecting fibers 30.

[0167] Because the distance between the connecting fibers 30 is relatively large, it is not easy to form a water film. When shrinking due to temperature disturbance, the loop changes shape, and the first mesh 111 and the second mesh 211 move closer to each other. This causes the connecting fibers 30 to be driven by the first mesh 111 and the second mesh 211 to follow the loop change, adjusting the position of the connecting fibers 30 as shown in Figure 14. The distance between the connecting fibers 30 is small, making it easier to form a water film. Furthermore, due to the expansion of the loop, a dense state of mutual compression is formed. The circumference of the loop and the positions of the first mesh 111 and the second mesh 211 are not much different, resulting in a uniform distribution of the first mesh 111 and the second mesh 211. The connecting fibers 30 are arranged more regularly, making it easier for a water film to form. This also improves the problem of reduced water-holding area and air contact area caused by the dense contact between the connecting fibers 30.

[0168] In one embodiment, at least one of the connecting portion 1120 of the base layer and the connecting fiber 30 includes a first fiber and a second fiber. The first fiber and the second fiber are made of different materials. The water absorption of the first fiber is greater than that of the second fiber.

[0169] That is, at least part of the connecting portion 1120 and / or at least part of the connecting fiber 30 are formed by bundling absorbent fibers and non-absorbent fibers. The first fiber is an absorbent fiber that absorbs water, achieving good water retention and enabling a continuous water supply. The second fiber is a non-absorbent fiber that promotes vaporization because the water held in the second fiber cannot penetrate deep into the second fiber, thus it is easily released and more easily dispersed into the air. At the same time, it can reduce the penetration of scale, making the fiber mesh 100 easier to clean.

[0170] In one embodiment, at least one of the connecting portion 1120 and the connecting fiber 30 has a protrusion on its surface. The protrusion is either a strip-shaped protrusion or a dot-shaped protrusion.

[0171] The protrusions can be protrusions extending along the length of the connecting portion 1120 and / or the connecting fiber 30, or protrusions extending in a circumferential or random direction. The protrusions can be narrow filaments or wide ribs. For example, a protrusion extending along the length of the connecting fiber 30 can be provided on each circumferential surface of the connecting fiber 30, resulting in an irregular cross-section of the connecting fiber 30, such as a triangle or a square with protruding sides. This helps increase the water-holding surface area of ​​the wire and / or connecting fiber 30, enabling more effective water retention, increasing the contact area between airflow and water, and improving humidification efficiency. The protrusions also do not have to be strip-shaped; they can be dot-shaped protrusions, resulting in an uneven dot-like structure on the surface of the connecting portion 1120 and / or the connecting fiber 30, forming a rough surface. The rough surface can be formed by physical deposition on the surface of the connecting part 1120 and / or the connecting fiber 30, which helps to increase the water-holding surface area, enabling more effective water retention, increasing the contact area between airflow and water, and improving humidification efficiency.

[0172] The base layer and connecting fiber 30 can be made of various materials and have various structures. The following are two specific examples of materials and structures. It should be understood that the connecting part 1120 of the base layer and the connecting fiber 30 are not limited to the following examples:

[0173] In one embodiment, the base layer is a polyester fiber fabric, specifically the connecting part 1120, which is also made of polyester fiber with a circular opening of 3 mm in diameter. The connecting fiber 30 is composed of nylon and cotton fibers bundled together, wherein the nylon fibers are non-absorbent and the cotton fibers are absorbent. The surface of the connecting fiber 30 is electroplated to form a micro-uneven structure that can retain water droplets. The spacing between adjacent base layers is 2 mm.

[0174] Alternatively, the adjacent base layers are a first base layer 10 and a second base layer 20, where the first base layer 10 is made of fiberglass fabric and the second base layer 20 is made of carbon fiber fabric. The opening is square with a side length of 4 mm. The connecting fiber 30 is made of aromatic polyamide fibers and amorphous metal fibers bundled together, wherein the aromatic polyamide fibers are absorbent fibers and the amorphous metal fibers are non-absorbent fibers and have antibacterial properties. The surface of the connecting fiber 30 is formed with a tiny uneven structure by chemical nickel plating. The distance between the first base layer 10 and the second base layer 20 is 3 mm.

[0175] As shown in Figures 11 to 13, a fourth aspect of this application provides a fabric 200, which includes multiple layers of fiber mesh 100 as provided in any of the above embodiments. Since the fabric 200 includes the fiber mesh 100, the beneficial effects of the fiber mesh 100 already explained will not be repeated in this application.

[0176] The multi-layered fiber mesh 100 in the fabric 200 are stacked together along a first direction. When the multi-layered fiber mesh 100 is stacked, the multi-layered fiber mesh 100 are staggered along a second direction.

[0177] The second direction can be a direction perpendicular to the first direction, that is, the second direction can be the paving direction of the first base layer 10 and the second base layer 20.

[0178] The projected areas of the openings in the multilayer fiber mesh 100 at least partially overlap to increase the gas-liquid exchange area of ​​the fabric 200. The first direction and the second direction are the X and Y directions shown in Figure 12, respectively.

[0179] Specifically, as shown in Figure 12, since the pair of first openings 11 and second openings 21 of each layer of fiber mesh 100 are correspondingly arranged along the first direction, the projection areas A of multiple openings at least partially overlap, forming an overlapping area A1. This is equivalent to the first openings 11 of the multiple layers of fiber mesh 100 being misaligned along the second direction. That is, when viewing from the first direction, or when observing the fabric 200 from above the first base layer 10 or the second base layer 20, the first base layer 10 or the second base layer 20 of the lower layer of fiber mesh 100 can be observed through the first opening 11 or the second opening 21 of the outermost layer of fiber mesh 100.

[0180] Thus, since the fiber mesh 100 in the fabric 200 of this application embodiment relies on the first base layer 10 and the second base layer 20 to absorb and store water, by staggering the multi-layer fiber mesh 100 along the second direction, when the airflow passes through the fabric 200, it can exchange gas and liquid with the first base layer 10 and the second base layer 20 of the outer fiber mesh 100, and then continue to exchange gas and liquid with the first base layer 10 and the second base layer 20 of the inner fiber mesh 100, thereby increasing the overall gas and liquid exchange area of ​​the fabric 200 and thus increasing the humidification capacity of the fabric 200 in a wet state.

[0181] In some embodiments, as shown in FIG13, the area of ​​the opening projection region A formed by a first opening 11 of a layer of fiber mesh 100 is S1, and the total area of ​​the multiple first connecting portions 110 of other layers of fiber mesh 100 projected into the opening projection region A is S2; the fiber overlap rate of the fabric 200 is B, B=S2 / S1, 0≤B≤95%.

[0182] Wherein, S1 is the area of ​​the projection region A of the opening of a first opening 11 of any layer of fiber mesh 100. Since the multi-layer fiber mesh 100 is staggered along the second direction, the projection region A of the opening of a layer of fiber mesh 100 will contain the projection of the first connecting part 110 / second connecting part 210 in the first base layer 10 / second base layer 20. That is, the hole structure formed by a set of first openings 11 and second openings 21 of a layer of fiber mesh 100 will be blocked by the first connecting part 110 or the second connecting part 210 in other layers of fiber mesh 100. See the top view of the multi-layer mesh from the first direction in Figure 13 for details. The total area of ​​the shaded part is S2. The shielding formed by these first connecting parts 110 / second connecting parts 210 increases the gas-liquid exchange area of ​​the fabric 200. That is, when the airflow passes through the first base layer 10 and the second base layer 20 of the fiber mesh fabric 100, it will not flow out of the fabric 200 directly, but will continue to flow through the multiple first connecting parts 110 in the first base layer 10 and the multiple second connecting parts 210 in the second base layer 20 of the next layer or several layers of fiber mesh fabric 100, thereby increasing the gas-liquid exchange area of ​​the fabric 200.

[0183] It is understandable that the larger the air-liquid exchange area of ​​the fabric 200, the higher its humidification capacity. However, its air resistance in a humid state will also increase accordingly, requiring it to be compatible with a humidifier 2000 with a higher power air supply device 2100. Conversely, the lower the overlap rate between the open projection areas of the multi-layer fiber mesh 100, the better it is compatible with a humidifier 2000 with a lower power air supply device 2100.

[0184] Thus, the fabric 200 provided in this embodiment can adjust the overlap rate of the projected areas of multiple openings of the multilayer fiber mesh 100 according to the power of the air supply device 2100 in the adapted humidification device 2000. After determining the required overlap rate of the fabric 200, the multilayer fiber mesh 100 is sewn together to obtain a fabric 200 that balances wind resistance and humidification performance in a humid state.

[0185] This application embodiment uses a fabric 200 comprising three layers of fiber mesh 100 to illustrate the overlap rate. The three layers of fiber mesh 100 may include a first fiber mesh 100, a second fiber mesh 100, and a third fiber mesh 100 stacked along a first direction.

[0186] For example, as shown in FIG13, the first fiber mesh 100a, the second fiber mesh 100b, and the third fiber mesh 100c respectively include a first base layer 10a, a first base layer 10b, and a first base layer 10c. The first fiber mesh 100a, the second fiber mesh 100b, and the third fiber mesh 100c can be misaligned along a second direction, such that the first connecting portion 110b of the second fiber mesh 100b and the first connecting portion 110c of the third fiber mesh 100c partially fall into the projection area A of the opening 11a of the first fiber mesh 100. The total area (dashed line portion) of the first connecting portion 110b and the first connecting portion 110c falling into the first opening 11a of the first fiber mesh 100 is S2 = 20% * S1, thus the overlap rate of the fabric 200 is B = S2 / S1 = 20%.

[0187] In some embodiments, the number of layers in the multilayer fiber mesh 100 is M, where 2≤M≤8.

[0188] M≥2. By increasing the number of layers of fiber mesh 100, the opening projection area A between different layers of fiber mesh 100 can overlap. Compared with a single-layer fiber mesh 100 fabric 200, a fabric 200 including multiple layers of fiber mesh 100 has higher humidification performance.

[0189] M≤8 can reduce the risk of excessive wind resistance in the fabric 200 when wet due to too many layers of fiber mesh 100, while also reducing the volume of fabric 200 and maintaining the miniaturization and portability of humidification device 2000.

[0190] In some embodiments, the thickness of the fabric 200 along the first direction is W2, wherein 6mm≤W2≤20mm.

[0191] As mentioned earlier, since the single-layer fiber mesh 100 can be made thinner, the multi-layered fabric 200 can also be made lighter and thinner, thus making it suitable for the smaller humidifier 2000.

[0192] W2 > 6mm, which improves the humidification performance of fabric 200 and the gas-liquid exchange area of ​​fabric 200.

[0193] W2≤20mm makes the fabric 200 thinner and lighter. Even with multiple layers of fiber mesh 100 stacked, the thickness of the fabric 200 is significantly thinner and lighter than the mesh thickness in related technologies (generally above 25mm).

[0194] Based on the above embodiments and referring to the experimental data in Table 2 below, the thickness W1 of the single-layer fiber mesh 100 is controlled between 1.5mm and 8.0mm. The first opening 11 or the second opening 21 is approximately hexagonal, with the long diagonal length L1 conforming to 2mm ≤ L1 ≤ 7mm, and the short diagonal length L2 conforming to 2mm ≤ L2 ≤ 6mm. The warp density E1 of the fiber mesh 100 is adjusted to conform to 16 threads / inch ≤ E1 ≤ 50 threads / inch, and the weft density E2 of the fiber mesh 100 is conforming to 14 threads / inch ≤ E2 ≤ 45 threads / inch. Simultaneously, the diameters of the first fiber filament 401 and the connecting fiber 30 are set according to the above embodiments. The resulting fabric 200, obtained by stacking multiple layers (N≥2) of fiber mesh 100, has a large humidification capacity.

[0195] Table 2

[0196] As shown in Table 2, factors such as the shape and size of the first opening 11 / second opening 21, the diameter of the connecting fiber 30, the diameter of the first fiber filament 401, and the weight of the fiber mesh 100 all affect the humidification capacity of the fabric 200. The fabrics 200 in Examples 1 and 2, which include two or more layers of fiber mesh 100, all possess good humidification capacity.

[0197] Based on the above embodiments and referring to the experimental data in Table 3 below, the thickness W1 of the single-layer fiber mesh 100 is controlled between 1.5mm and 8.0mm. The first opening 11 or the second opening 21 is in the form of a hexagon. The length of the long diagonal L1 of the hexagon meets the requirement of 2mm≤L1≤7mm, and the length of the short diagonal L2 of the hexagon meets the requirement of 2mm≤L2≤6mm. The warp density E1 of the fiber mesh 100 is adjusted to meet the requirement of 16 threads / inch≤E1≤50 threads / inch, and the weft density E2 of the fiber mesh 100 meets the requirement of 14 threads / inch≤E2≤45 threads / inch. At the same time, the diameter of the first fiber filament 401 and the connecting fiber 30 is set according to the above embodiments.

[0198] Table 3

[0199] As shown in Tables 2 and 3, the wind resistance of the fabric 200 increases with the number of layers of the fiber mesh 100. Specifically, the fabrics 200 in Examples 1 and 2, which include two layers of fiber mesh 100, exhibit significantly lower wind resistance than the fabric 200 in Comparative Example 1, which includes two layers of mesh. Furthermore, in Example 1, the fabric 200 includes five layers of fiber mesh 100, resulting in a total thickness of 15 mm. In Example 2, the fabric 200 includes three layers of fiber mesh 100, resulting in a total thickness of 13.5 mm. Even with a thickness close to the 18 mm thickness of the fabric 200 in Comparative Example 1, Examples 1 and 2 still exhibit lower wind resistance compared to Comparative Example 1.

[0200] Tables 1 to 3 above demonstrate that the fiber mesh 100 / woven fabric 200 provided in this application embodiment has a higher water absorption ratio, lower ventilation resistance, and greater humidification capacity compared to related technologies.

[0201] Considering that in related technologies, the three-dimensional fabric of humidifying equipment has water retention properties, the three-dimensional fabric is prone to deformation or collapse after absorbing water and humidifying or during long-term use, causing the three-dimensional fabric to be in a loose state, resulting in uneven local water absorption effect of the three-dimensional fabric, thereby reducing the water absorption and seepage efficiency of the three-dimensional fabric. The fifth aspect of the embodiments of this application provides a water absorption component 3000, as shown in Figures 29 to 33. The water absorption component 3000 includes: a woven fabric 200 and a sealing fabric 500. The woven fabric 200 is used to absorb liquid, and the sealing fabric 500 is connected to the end of the woven fabric 200 and covers at least a portion of the woven fabric 200 along a fifth direction, which is the thickness direction of the woven fabric 200.

[0202] In this embodiment, the fabric 200 has good water absorption properties, and moisture can be adsorbed on the surface or inside of the fabric 200. Airflow passes through the fabric 200 and carries away the moisture in the fabric 200 to increase the humidity in the air.

[0203] The edge-sealing fabric 500 is located on the outside of the fabric 200 and connected to its ends. The fabric 200 has a windward side, a leeward side, and end faces. The windward side is located on the side of the fabric 200 facing the airflow, and the windward side is opposite to the leeward side. The two ends of the end faces are connected to the windward side and the leeward side, respectively. The distance between the windward side and the leeward side is the thickness of the fabric 200, and the fifth direction is the thickness direction of the fabric 200, as shown in Figure 33, where the arrow at X3 points to the fifth direction. The edge-sealing fabric 500 covers at least a portion of the outer end of the fabric 200 along the fifth direction, so that the edge-sealing fabric 500 covers at least a portion of the end faces of the fabric 200.

[0204] The edge-sealing fabric 500 covers the end face of the fabric 200, thus fixing at least part of the edge of the fabric 200 and achieving an edge-sealing effect. The edge-sealing fabric 500 provides structural support to the end of the fabric 200, improving the stability of the fabric 200's shape, reducing deformation or collapse, and ensuring sufficient contact area between the fabric 200 and airflow / water flow. This results in uniform localized water absorption and ventilation, thereby improving the fabric 200's moisture retention and evaporation effects. Furthermore, the fabric 200's structural shape easily creates gaps at the edges; the edge-sealing fabric 500 wraps around these edges, making the edges of the absorbent component 3000 smoother, increasing the contact area between the absorbent component 3000 and the drain outlet cross-section, and improving the water-guiding effect of the absorbent component 3000. In addition, the edge sealing fabric 500 has good air permeability and permeability. The liquid first contacts the edge sealing fabric 500 and then enters the fabric 200. When the liquid flows through the edge sealing fabric 500, it undergoes penetration and diffusion, which improves the uniformity of liquid distribution. This allows the edge sealing fabric 500 to evenly distribute water to the fabric 200 below, thus optimizing the water absorption effect of the fabric 200.

[0205] Both Fabric 200 and Edge Sealing Fabric 500 are fabrics, also known as Fabric 200 or textiles. For example, the fabric can be a single-layer porous substrate formed from synthetic fibers (such as polyester or nylon) or natural fibers (cotton yarn) through a weaving process, with regularly distributed geometric openings (such as regular hexagons or squares, diagonal 2-12 mm) on its surface and a mesh density of 5-30 meshes / cm². 2 This fabric, serving as the core layer of the 3000 water-absorbing component, is connected to another layer of fabric at intervals via vertically or curved connecting fibers (4-50 fibers per bundle), forming a continuous three-dimensional air channel. The fiber surface can be treated with hydrophilic or hydrophobic agents to regulate moisture retention (1.2-2.8 g / g), and the adhesion of the water film is enhanced through micron-level roughness (Ra≤50μm). Its low-resistance design (pressure loss ≤20Pa at a face velocity of 1m / s) and anti-scaling properties make it compatible with rotary, immersion, and drip humidifiers (2000 type), achieving efficient and stable humidification with a humidity increase rate >0.8 g / (m³). 3 ·min).

[0206] For example, the fabric can be a three-dimensional filter substrate, consisting of two layers of woven substrate with regular openings (e.g., regular hexagons, diagonal > 3 mm) connected vertically or curvedly by multiple connecting fiber bundles (4-50 fibers / bundle, single fiber outer perimeter 45-450 μm). This fabric utilizes inter-fiber capillary action and a micron-level surface texture to retain water (1.45-2.55 g / g), while simultaneously reducing air resistance as it passes through the openings. The fiber material can be polyester, nylon, or cotton yarn, and can be treated with hydrophilic / hydrophobic agents or have antibacterial agents added, adapting to rotating cylinders or strip structures to achieve uniform wetting. Compared to traditional honeycomb structures, its three-dimensional fiber network increases the gas-liquid contact area by three times, effectively inhibiting scale buildup and clogging. It combines high humidification efficiency (humidity > 60% RH at a face velocity of 1 m / s) with low energy consumption, making it suitable for long-term, stable humidification applications such as air purifiers.

[0207] For example, the material hardness of the edge-sealing fabric 500 is greater than or equal to the material hardness of the fabric 200. The material of the edge-sealing fabric 500 can be thermoplastic polyester or saturated polyester, such as polyester resin.

[0208] In some embodiments, as shown in Figures 31 and 33, the edge-sealing fabric 500 covers at least a portion of the fabric 200 along a sixth direction, which is the direction from the outer end of the fabric 200 toward the center.

[0209] In this embodiment, the sixth direction is the direction from the outer end of the fabric 200 to the center of the fabric 200, as shown in FIG33. The arrow at Y3 points to the sixth direction, and the fifth direction intersects with the sixth direction. Exemplarily, the fifth direction and the sixth direction can be perpendicular to each other.

[0210] In one possible embodiment, the edge sealing fabric 500 can be a right-angled structure, with the two right-angled sides of the right-angled structure extending along the first direction and the sixth direction respectively, so that the edge sealing fabric 500 covers at least part of the end face of the fabric 200 along the fifth direction.

[0211] The edge-sealing fabric 500 covers the fabric 200 in two directions, increasing its support strength and further improving the stability of the fabric 200's shape, thereby enhancing its moisture retention and evaporation effects. Furthermore, the edge-sealing fabric 500 is bent and folded over the ends of the fabric 200, facilitating its attachment and making it easier for workers to sew the edges of the fabric 200.

[0212] In some embodiments, as shown in FIG29, the fabric 200 has a tubular structure, and the edge-sealing fabric 500 wraps the top and / or bottom of the fabric 200.

[0213] In some other embodiments, as shown in FIG30, the fabric 200 is a plate-shaped structure, the outline of which can be polygonal or circular, and the edge-sealing fabric 500 wraps around the edge of the fabric 200.

[0214] In some embodiments provided in this application, as shown in FIG37, the edge sealing fabric 500 is provided with a liquid guiding hole 510, which extends along the fifth or sixth direction and is used to guide liquid outside the edge sealing fabric 500 to the fabric 200.

[0215] In this embodiment, the liquid guiding hole 510 penetrates both the inner and outer sides of the edge-sealing fabric 500. When the liquid guiding hole 510 penetrates along the fifth direction, it faces the windward or leeward side of the fabric 200. When the liquid guiding hole 510 penetrates along the sixth direction, it faces the end face of the fabric 200. After contacting the edge-sealing fabric 500, the liquid can flow through the liquid guiding hole 510 to the end of the fabric 200. The liquid guiding hole 510 realizes the function of guiding the liquid, improving the liquid conduction efficiency of the edge-sealing fabric 500, and thus improving the water absorption effect of the fabric 200.

[0216] In some embodiments provided in this application, as shown in Figures 31, 33, and 37, the edge-sealing fabric 500 includes a first edge-sealing portion 520 and a second edge-sealing portion 530, wherein the first edge-sealing portion 520 extends along a fifth direction and the second edge-sealing portion 530 extends along a sixth direction. The number of liquid-guiding holes 510 is plurality of, and the plurality of liquid-guiding holes 510 are respectively located in the first edge-sealing portion 520 and the second edge-sealing portion 530.

[0217] In this embodiment, the positions of the liquid guiding holes 510 are defined. A first sealing portion 520 extending along the fifth direction covers at least a portion of the end face of the fabric 200, and a second sealing portion 530 extending along the sixth direction covers at least a portion of the windward or leeward side of the fabric 200. Both the first sealing portion 520 and the second sealing portion 530 are provided with multiple liquid guiding holes 510, located on different end faces of the sealing fabric 500. Liquid can enter the fabric 200 through multiple end faces, improving the uniformity and efficiency of liquid conduction in the sealing fabric 500. Furthermore, airflow can flow to the fabric 200 through the liquid guiding holes 510 on the second sealing portion 530, preventing the sealing portion from affecting the contact between the fabric 200 and the airflow, thus improving the ventilation effect of the absorbent assembly 3000.

[0218] In some embodiments provided in this application, as shown in Figures 31, 33 and 37, the number of second edge sealing portions 530 is at least two, and the two second edge sealing portions 530 are respectively disposed on both sides of the fabric 200.

[0219] In this embodiment, two second edge-sealing portions 530 are respectively disposed on both sides of the fabric 200, so that the edge-sealing fabric 500 can simultaneously cover the windward and leeward sides of the fabric 200, expanding the wrapping range of the edge-sealing fabric 500 on the outer end of the fabric 200, enabling the edge-sealing fabric 500 to simultaneously support both sides of the fabric 200, thereby improving the support strength and support effect of the edge-sealing fabric 500 on the fabric 200.

[0220] In some embodiments provided in this application, as shown in FIG37, the shape of the liquid guide hole 510 includes a circle or a polygon, wherein the diameter of the circle or the longest diagonal of the polygon is less than or equal to 5 mm.

[0221] In this embodiment, the liquid guiding hole 510 can be a circular through hole or a polygonal through hole. When the liquid guiding hole 510 is a circular through hole, the diameter of the circle is less than or equal to 5 mm. When the liquid guiding hole 510 is a polygonal through hole, the longest diagonal of the polygon is less than or equal to 5 mm. The diagonal of the polygon is the distance between the two endpoints. When the polygon is a triangle, the longest diagonal of the polygon is the maximum side length of the triangle.

[0222] By limiting the size of the liquid guiding hole 510, the opening of the liquid guiding hole 510 is made smaller. It can be understood that the smaller the opening, the more pronounced the surface tension of the liquid within the liquid guiding hole 510, making it easier for the liquid to form a convex liquid surface within the liquid guiding hole 510. This increases the surface energy of the liquid, making it easier for the liquid to penetrate the edge-sealing fabric 500. This improves the efficiency of liquid penetration into the edge-sealing fabric 500, thereby improving the efficiency of the edge-sealing fabric 500 in guiding liquid flow to the fabric 200, and further enhancing the humidification performance of the absorbent component 3000.

[0223] In some embodiments provided in this application, as shown in FIG33, the edge-sealing fabric 500 covers the fabric 200 in the sixth direction for a length of 1 cm to 3 cm.

[0224] In this embodiment, F in Figure 33 represents the coverage length of the edge-sealing fabric 500 in the sixth direction. By limiting the length of the edge-sealing fabric 500 in the sixth direction, the coverage range of the edge-sealing fabric 500 on the outer edge of the fabric 200 is limited. This allows the edge-sealing fabric 500 to extend to a position 1cm to 3cm from the end face on the windward or leeward side of the fabric 200, ensuring that the wrapping range of the edge-sealing fabric 500 is within a reasonable range. This prevents the coverage range of the edge-sealing fabric 500 from being too small, resulting in weak support strength, and also prevents the coverage range of the edge-sealing fabric 500 from being too large, which would affect the contact between the fabric 200 and airflow and water flow.

[0225] In some embodiments provided in this application, as shown in FIG33, the distance between the two end faces of the fabric 200 along the fifth direction is H1, and the thickness of the first edge sealing portion 520 and the second edge sealing portion 530 is H2, H2≤0.2H1, and / or H2≤2mm.

[0226] In this embodiment, the distance between the windward and leeward sides of the fabric 200 is H1, and the thickness of the first edge sealing portion 520 and the second edge sealing portion 530 is the same, both being H2. By limiting the thickness of the edge sealing fabric 500, the edge sealing fabric 500 is made relatively thin, which improves the air permeability and permeability of the edge sealing fabric 500, thereby improving the humidification effect of the water absorption component 3000.

[0227] In some embodiments provided in this application, as shown in FIG38, the edge sealing fabric 500 has a multi-layer structure, including a first fabric 540 and a second fabric 550 stacked together, with the first fabric 540 covering the outside of the second fabric 550.

[0228] In this embodiment, the first fabric 540 and the second fabric 550 are stacked, with the first fabric 540 covering the outside of the second fabric 550, so that the edge sealing fabric 500 forms a multi-layer structure. The first fabric 540 and the second fabric 550 together wrap the outer end of the fabric 200, which improves the overall structural strength of the edge sealing fabric 500, thereby improving the support effect of the edge sealing fabric 500 on the fabric 200 and improving the stability of the water absorption component 3000.

[0229] In some embodiments provided in this application, as shown in FIG38, the edge sealing fabric 500 further includes: edge sealing connecting fiber 56030, the two ends of which are respectively connected to the first fabric 540 and the second fabric 550.

[0230] In this embodiment, the multi-layered feature of the edge-sealing fabric 500 is further defined, and the number of edge-sealing connecting fibers 56030 can be multiple. The edge-sealing connecting fibers 56030 are located between the first fabric 540 and the second fabric 550, connecting the first fabric 540 and the second fabric 550. This further improves the structural strength of the edge-sealing fabric 500, thereby enhancing its support effect on the woven fabric 200 and improving the stability of the absorbent assembly 3000. Furthermore, the edge-sealing connecting fibers 56030 can store and guide liquid flowing through the first fabric 540, improving the liquid-guiding efficiency and permeation uniformity of the edge-sealing fabric 500.

[0231] In some embodiments provided in this application, as shown in FIG38, the first fabric 540 is provided with a first through hole 541, and the second fabric 550 is provided with a second through hole 551. The shapes of the first through hole 541 and the second through hole 551 include circles or polygons. The diameter or longest diagonal length of the first through hole 541 is D1, and the diameter or longest diagonal length of the second through hole 551 is D2, where D1≥D2.

[0232] In this embodiment, the multi-layer feature of the edge-sealing fabric 500 is further defined. The liquid guiding hole 510 of the first fabric 540 is a first through hole 541, and the liquid guiding hole 510 of the second fabric 550 is a second through hole 551. The first through hole 541 and the second through hole 551 can be circular or polygonal through holes. The diameter or longest diagonal length of the first through hole 541 is D1, and the diameter or longest diagonal length of the second through hole 551 is D2, where D1≥D2. This makes the opening size of the first through hole 541 greater than or equal to the opening size of the second through hole 551, so that the liquid permeation effect of the inner fabric is greater than that of the outer fabric. This allows the fluid to quickly penetrate into the inner fabric after flowing through the outer fabric, further improving the liquid permeation efficiency of the edge-sealing fabric 500 and preventing liquid from accumulating inside the edge-sealing fabric 500.

[0233] In some embodiments provided in this application, D1 is 8 to 12 times D2.

[0234] In this embodiment, the opening size of the sealing fabric 500 is further defined. For example, D1 can be 8 times, 10 times, or 12 times D2. By limiting the size of the liquid guiding holes 510 of each layer of the multi-layer sealing fabric 500 within a reasonable range, the opening size of the first through hole 541 is much larger than the opening size of the second through hole 551, making the liquid permeation effect of the inner layer fabric much greater than that of the outer layer fabric, thereby improving the liquid permeation efficiency of the multi-layer sealing fabric 500.

[0235] In some embodiments provided in this application, there are multiple fabrics 200, which are stacked together, and the edge sealing fabric 500 covers the ends of the multiple fabrics 200.

[0236] In this embodiment, multiple fabrics 200 are stacked, forming a multi-layered structure that improves the water absorption and evaporation effects of the absorbent assembly 3000. The edge-sealing fabric 500, by wrapping the ends of the multiple fabrics 200, effectively seals the edges, reducing the number of edge-sealing fabrics 500 required. Furthermore, the multiple fabrics 200 are connected by the edge-sealing fabric 500, improving the overall structural strength and morphological stability of the multiple fabrics 200. The edge-sealing fabric 500 also guides liquid to the ends of the multiple fabrics 200, improving the uniformity of liquid permeation.

[0237] For example, the number of fabrics 200 can be 4 to 6.

[0238] In some embodiments provided in this application, as shown in Figures 34, 35 and 36, the fabric 200 includes: a first base layer 10, a second base layer 20 and connecting fibers 30. The first base layer 10 is provided with a first opening 11. The second base layer 20 is spaced apart from the first base layer 10 along a fifth direction and is provided with a second opening 21. The connecting fibers 30 are respectively connected to the first base layer 10 and the second base layer 20.

[0239] In this embodiment, the structure of the fabric 200 is defined, with a first base layer 10 and a second base layer 20 disposed opposite to each other, and the windward and leeward sides respectively disposed on the first base layer 10 and the second base layer 20. A first opening 11 and a second opening 21 are connected to form an airflow passage, allowing airflow to exit through the second opening 21 after entering the first opening 11. A connecting fiber 30 is located between the first base layer 10 and the second base layer 20, connecting the first base layer 10 and the second base layer 20, thus forming a three-dimensional structure for the fabric 200.

[0240] In one embodiment, there are multiple connecting fibers 30, and each connecting fiber 30 is connected to the first base layer 10 and the second base layer 20 respectively.

[0241] In another embodiment, the number of connecting fibers 30 is one, and the connecting fiber 30 continuously passes through the plurality of first openings 11 and the plurality of second openings 21.

[0242] The connecting fibers 30 can absorb liquid or allow liquid to adhere to the fiber surface, increasing the surface area of ​​the fabric 200. This improves the adsorption efficiency of the fabric 200 for liquid, thereby enhancing its water absorption and evaporation effects. Furthermore, during the evaporation process, scale easily precipitates on the fabric 200. This three-dimensional structure improves the water retention and air permeability of the fabric 200, thus preventing scale from reducing its humidification capacity.

[0243] For example, the materials of the first base layer 10 and the second base layer 20 can be at least one of natural fibers, metal fibers or resin fibers, and the material of the connecting fiber 30 can be a resin material.

[0244] In some embodiments provided in this application, as shown in Figures 34 and 36, the shapes of the first opening 11 and the second opening 21 include circles or polygons, wherein the diameter of the circle or the longest diagonal of the polygon is greater than or equal to 2 mm.

[0245] In this embodiment, when the first opening 11 and the second opening 21 are circular through holes, the diameter of the circle is less than or equal to 2 mm. When the first opening 11 and the second opening 21 are polygonal through holes, the longest diagonal of the polygon is less than or equal to 2 mm, and the diagonal of the polygon is the distance between its two endpoints. When the polygon is a triangle, the longest diagonal of the polygon is the longest side length of the triangle. By limiting the minimum threshold of the vent holes on the fabric 200, the opening size is limited to a reasonable range to prevent the opening from being too small, which would cause the liquid to form a film and block the opening. This suppresses the increase in pressure loss during liquid supply, improves the flow state of the first opening 11 and the second opening 21, improves the air permeability of the fabric 200, and thus improves the humidification effect of the fabric 200.

[0246] In some embodiments provided in this application, as shown in FIG36, a plurality of connecting fibers 30 form a group of connecting fibers 30 around the first opening 11, and the number of connecting fibers 30 in the group of connecting fibers 30 is 4 to 50.

[0247] In this embodiment, the number of connecting fibers 30 surrounding the first vent is limited, allowing liquid to adhere not only to the connecting fibers 30 but also to the gaps between adjacent connecting fibers 30 through capillary action. This increases the amount of liquid adhering to the connecting fibers 30 and improves the moisturizing effect of the fabric 200. Furthermore, it prevents an excessive number of connecting fibers 30 from hindering airflow within the fabric 200.

[0248] The fifth aspect of this application provides a humidification device 2000, including a fiber mesh 100 as described in the first aspect, or a fiber mesh 100 as described in the second aspect, or a fiber mesh 100 as described in the third aspect, or a fabric 200 as described in the fourth aspect.

[0249] The humidification device 2000 provided in this application embodiment includes the fiber mesh 100 or fabric 200 as described in any of the above technical solutions. Therefore, the humidification device 2000 has all the beneficial effects of the fiber mesh 100 or fabric 200 of the above technical solutions, which will not be elaborated here.

[0250] As shown in Figure 39, the humidification device 2000 includes: an air supply device 2100 and a water absorption component 3000 provided in any of the first aspects of the above embodiments, wherein the air supply device 2100 and the water absorption component 3000 are arranged opposite to each other.

[0251] In this embodiment, the airflow blown out by the air supply device 2100 can pass through the water absorption component 3000 and introduce the moisture on the water absorption component 3000 into the airflow, thereby increasing the moisture content in the air and humidifying the air.

[0252] It should be noted that the humidifying device 2000 includes the water absorption component 3000 provided in any of the above embodiments, and therefore has all the beneficial technical effects of the water absorption component 3000. To avoid repetition, it will not be described in detail here.

[0253] This application also provides a humidifying device 2000, which includes the fabric 200 provided in any embodiment of this application, or the fiber mesh 100 provided in any of the above embodiments. Since the humidifying device 2000 includes the fiber mesh 100 or the fabric 200, the beneficial effects of the fiber mesh 100 and the fabric 200 that have already been explained will not be repeated in this application.

[0254] In some embodiments, the humidifying device 2000 includes a liquid supply assembly. The liquid supply assembly is used to supply liquid to the fabric 200. Exemplarily, the liquid supply assembly may include a water tank and a liquid supply line connected to the water tank, with the outlet of the liquid supply line facing the fabric 200 to wet the fabric 200.

[0255] In some embodiments, the humidifier 2000 further includes an air supply device 2100. The air supply device 2100 is used to agitate the airflow and allow the airflow to pass through the fabric 200, causing the moisture on the fabric 200 to evaporate and flow with the airflow into the indoor environment, thereby humidifying the air.

[0256] In some embodiments, the rated rotational speed of the air supply device 2100 is positively correlated with the fiber overlap rate B of the fabric 200.

[0257] The rated speeds of the air supply device 2100 in the humidifier 2000 differ. If the rated speed of the air supply device 2100 is low and the fiber overlap rate of the matched fabric 200 is high, the gas-liquid exchange effect between the airflow and the fabric 200 will be affected, making it difficult for moisture to fully enter the indoor environment with the airflow, thus affecting the humidification efficiency of the humidifier 2000. Conversely, if the rated speed of the air supply device 2100 is high, and the fiber overlap rate of the matched fabric 200 is low, the faster-flowing airflow may not fully exchange gas and liquid with the fabric 200 before entering the indoor environment, similarly affecting the humidification efficiency of the humidifier 2000. Therefore, in this embodiment of the humidifier 2000, the fiber overlap rate B of the fabric 200 is configured according to the rated speed of the air supply device 2100, so that the rated speed of the air supply device 2100 is positively correlated with the fiber overlap rate of the fabric 200, thereby optimizing the humidification effect of the humidifier 2000.

[0258] In some embodiments, the rated rotational speed of the air supply device 2100 is V1, and the overlap rate of the open projection area A of the multilayer fiber mesh 100 is B, wherein V1 ≤ 0.8 m / s, and 0% < B ≤ 20%.

[0259] Because the rated speed of the air supply device 2100 is relatively low, the airflow speed is usually slow when passing through the fabric 200. In order to make the gas-liquid exchange between the airflow and the fabric 200 more complete, 0% < B ≤ 20% can reduce the risk of airflow obstruction caused by the high overlap rate of the opening projection area A of the multi-layer fiber mesh 100. This makes the ventilation resistance of the fabric 200 relatively low, so that even a low wind speed can pass through the fabric 200 smoothly, and the humidifier 2000 can achieve the ideal humidification effect.

[0260] In some embodiments, the rated rotational speed of the air supply device 2100 is V1, and the overlap rate of the open projection area A of the multilayer fiber mesh 100 is B, wherein 0.8m / s < V1 ≤ 2m / s, and 20% < B < 70%.

[0261] Since the rated speed of the air supply device 2100 is moderate, the airflow speed is relatively fast when passing through the fabric 200. At this time, the overlap rate of the opening projection area A of 20% < B < 70% can appropriately increase the contact area between the airflow and the fabric 200 while maintaining a certain ventilation efficiency, promote gas-liquid exchange, improve the humidification efficiency of the fabric 200, and at the same time reduce the risk of excessive overlap rate causing excessive ventilation resistance of the fabric 200 and affecting airflow.

[0262] In some embodiments, the rated rotational speed of the air supply device 2100 is V1, and the overlap rate of the open projection area A of the multilayer fiber mesh 100 is B, wherein V1 > 2 m / s and 70% ≤ B < 95%.

[0263] When the rated speed of the air supply device 2100 is high, the airflow passes through the fabric 200 at a relatively faster speed. At this point, a higher overlap rate (70% ≤ B < 95%) is required to ensure sufficient contact time and area between the airflow and the fabric 200, achieving adequate gas-liquid exchange and the desired humidification effect. Although this may increase the ventilation resistance of the fabric 200, the high-speed airflow can overcome this resistance and improve the humidification effect of the humidification device 2000.

[0264] The humidification device 2000 in this application embodiment was tested using the fabric 200 in Example 1 of the above experiment. The fabric 200 in Example 1 includes four layers of fiber mesh 100. The fiber overlap rate of the four layers of fabric 200 in Example 1 was adjusted to 50% and 80% respectively. Then, the air supply device 2100 was configured with four different speeds for the experiment.

[0265] Table 4

[0266] As shown in Table 4, when the air supply device 2100 of the humidifier 2000 rotates at a lower speed and the fiber overlap rate of the fabric 200 is lower, the humidification capacity is higher compared to when the fiber overlap rate of the fabric 200 is higher. Furthermore, the higher the rotation speed of the air supply device 2100, the higher the humidification capacity of the humidifier 2000.

[0267] Furthermore, this application also provides a humidification device 2000, including at least one fiber mesh 100 as described above. One or more fiber meshes 100 can be provided as needed. The fiber meshes 100 can be arranged in a cylindrical shape as shown in Figure 25, or laid flat as shown in Figure 27. When multiple fiber meshes 100 are used, they can be closely joined as shown in Figure 25, fixed by sewing, and integrally fitted onto a single fixing frame. Alternatively, they can be spaced apart as shown in Figure 28, each using its own fixing device.

[0268] The fiber mesh 100 shown in Figure 27 can be stretched radially to form the stretched state shown in Figure 26. The fiber mesh 100 shown in Figure 27 can also be stretched in a planar direction to form the stretched state shown in Figure 28. Furthermore, the fiber mesh 100 can also be contracted radially.

[0269] The humidifier 2000 also includes a support frame, a water supply mechanism, and an air-driven mechanism. The fiber mesh 100 is connected to the support frame. The water supply mechanism supplies water to the fiber mesh 100 through spraying or other means to keep the fiber mesh 100 moist. The air-driven mechanism supplies air to the fiber mesh 100 through a blower 2100 or similar means. The air flows from at least one side of the fiber mesh 100 to the other, passes through the fiber mesh 100, and carries the moisture held on the fiber mesh 100 into the environment, thereby increasing the humidification of the environment.

[0270] The humidification device 2000 includes at least one embodiment of the fiber mesh 100 of any of the above, and includes the advantages of the fiber mesh 100 of any of the above, which will not be repeated here.
