Detailed Implementation

[0033] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0034] The first aspect of this application provides a water-absorbing component 10, such as... Figures 1 to 5 As shown, the absorbent assembly 10 includes a three-dimensional fabric 100 and a sealing fabric 200. The three-dimensional fabric 100 is used to absorb liquid, and the sealing fabric 200 is connected to the end of the three-dimensional fabric 100 and covers at least a portion of the three-dimensional fabric 100 along a first direction, which is the thickness direction of the three-dimensional fabric 100.

[0035] In this embodiment, the three-dimensional fabric 100 has good water absorption properties, and moisture can be adsorbed on the surface or inside of the three-dimensional fabric 100. Airflow passes through the three-dimensional fabric 100 and carries away the moisture in the three-dimensional fabric 100 to increase the humidity in the air.

[0036] The edge-sealing fabric 200 is located outside the three-dimensional fabric 100 and connected to its ends. The three-dimensional fabric 100 has a windward side 112, a leeward side 122, and end faces. The windward side 112 is located on the side of the three-dimensional fabric 100 facing the airflow, and the windward side 112 is opposite to the leeward side 122. The two ends of the end faces are respectively connected to the windward side 112 and the leeward side 122. The distance between the windward side 112 and the leeward side 122 is the thickness of the three-dimensional fabric 100, and the first direction is the thickness direction of the three-dimensional fabric 100, such as... Figure 5 As shown, the arrow at point X points in the first direction. The edge-sealing fabric 200 covers at least a portion of the outer end of the three-dimensional fabric 100 along the first direction, such that the edge-sealing fabric 200 covers at least a portion of the end face of the three-dimensional fabric 100.

[0037] The edge-sealing fabric 200 covers the end face of the three-dimensional fabric 100, enabling it to fix at least a portion of the edge of the three-dimensional fabric 100, thus achieving an edge-sealing effect. The edge-sealing fabric 200 provides structural support to the ends of the three-dimensional fabric 100, improving the stability of its shape, reducing deformation or collapse, and ensuring sufficient contact area between the three-dimensional fabric 100 and airflow / water flow. This results in uniform local water absorption and ventilation, thereby improving the moisture retention and evaporation effects of the three-dimensional fabric 100. Furthermore, the structural shape of the three-dimensional fabric 100 easily creates gaps at its edges; the edge-sealing fabric 200 can wrap around these edges, making the edges of the absorbent component 10 smoother, increasing the contact area between the absorbent component 10 and the drain outlet cross-section, and improving the water-guiding effect of the absorbent component 10. In addition, the edge sealing fabric 200 has good air permeability and permeability. The liquid first contacts the edge sealing fabric 200 and then enters the three-dimensional fabric 100. When the liquid flows through the edge sealing fabric 200, it undergoes permeation and diffusion, which improves the uniformity of liquid distribution. This allows the edge sealing fabric 200 to play a role in evenly distributing water to the three-dimensional fabric 100 below, thus optimizing the water absorption effect of the three-dimensional fabric 100.

[0038] Both the three-dimensional fabric 100 and the edge-sealing fabric 200 are fabrics, also known as textiles 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, with a diagonal of 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 water-absorbing component 10, is connected to another fabric layer intermittently 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, achieving efficient and stable humidification with a humidity increase rate >0.8 g / (m²). 3 ·min).

[0039] 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.

[0040] For example, the material hardness of the edge-sealing fabric 200 is greater than or equal to the material hardness of the three-dimensional fabric 100. The material of the edge-sealing fabric 200 can be thermoplastic polyester or saturated polyester, such as polyester resin.

[0041] In some embodiments, such as Figure 3 and Figure 5 As shown, the edge-sealing fabric 200 covers at least a portion of the three-dimensional fabric 100 along a second direction, which is the direction from the outer end of the three-dimensional fabric 100 toward the center.

[0042] In this embodiment, the second direction is the direction from the outer end of the three-dimensional fabric 100 to the center of the three-dimensional fabric 100, such as... Figure 5 As shown, the arrow at point Y points in the second direction, where the first and second directions intersect. For example, the first and second directions can be perpendicular to each other.

[0043] In one possible embodiment, the edge sealing fabric 200 can be a right-angled structure, with the two right-angled sides of the right-angled structure extending along a first direction and a second direction respectively, so that the edge sealing fabric 200 covers at least a portion of the end face of the three-dimensional fabric 100 along the first direction.

[0044] The edge-sealing fabric 200 covers the three-dimensional fabric 100 in two directions, increasing the support strength of the edge-sealing fabric 200 for the three-dimensional fabric 100 and further improving the stability of the three-dimensional fabric 100's shape, thereby enhancing the moisture retention and evaporation effects of the three-dimensional fabric 100. Furthermore, the edge-sealing fabric 200 is bent and covers the ends of the three-dimensional fabric 100, facilitating the fixing of the edge-sealing fabric 200 to the three-dimensional fabric 100 and making it easier for workers to perform edge-sewing operations on the three-dimensional fabric 100.

[0045] In some embodiments, such as Figure 1As shown, the three-dimensional fabric 100 has a tubular structure, and the edge-sealing fabric 200 wraps the top and / or bottom of the three-dimensional fabric 100.

[0046] In other embodiments, such as Figure 2 As shown, the three-dimensional fabric 100 has a plate-shaped structure, and the outline of the plate-shaped structure can be polygonal or circular. The edge-sealing fabric 200 wraps around the edge of the three-dimensional fabric 100.

[0047] In some embodiments provided in this application, such as Figure 9 As shown, the edge sealing fabric 200 is provided with a liquid guiding hole 210, which is through in a first direction or a second direction. The liquid guiding hole 210 is used to guide the liquid outside the edge sealing fabric 200 to the three-dimensional fabric 100.

[0048] In this embodiment, the liquid guiding hole 210 penetrates both the inner and outer sides of the sealing fabric 200. When the liquid guiding hole 210 is connected along the first direction, it faces the windward side 112 or the leeward side 122 of the three-dimensional fabric 100. When the liquid guiding hole 210 is connected along the second direction, it faces the end face of the three-dimensional fabric 100. After contacting the sealing fabric 200, the liquid can flow through the liquid guiding hole 210 to the end of the three-dimensional fabric 100. The liquid guiding hole 210 realizes the guiding function of the liquid, improves the liquid conduction efficiency of the sealing fabric 200, and thus improves the water absorption effect of the three-dimensional fabric 100.

[0049] In some embodiments provided in this application, such as Figure 3 , Figure 5 and Figure 9 As shown, the edge-sealing fabric 200 includes a first edge-sealing portion 220 and a second edge-sealing portion 230, wherein the first edge-sealing portion 220 extends along a first direction and the second edge-sealing portion 230 extends along a second direction. The number of liquid-guiding holes 210 is plurality of, and the plurality of liquid-guiding holes 210 are respectively located in the first edge-sealing portion 220 and the second edge-sealing portion 230.

[0050] In this embodiment, the positions of the liquid guiding holes 210 are defined. A first sealing portion 220 extending along a first direction covers at least a portion of the end face of the three-dimensional fabric 100, and a second sealing portion 230 extending along a second direction covers at least a portion of the windward side 112 or leeward side 122 of the three-dimensional fabric 100. Both the first sealing portion 220 and the second sealing portion 230 are provided with multiple liquid guiding holes 210, so that the liquid guiding holes 210 are located on different end faces of the sealing fabric 200. Liquid can enter the three-dimensional fabric 100 through multiple end faces, improving the uniformity and efficiency of liquid conduction in the sealing fabric 200. Furthermore, airflow can flow to the three-dimensional fabric 100 through the liquid guiding holes 210 on the second sealing portion 230, preventing the sealing portion from affecting the contact between the three-dimensional fabric 100 and the airflow, thus improving the ventilation effect of the absorbent assembly 10.

[0051] In some embodiments provided in this application, such as Figure 3 , Figure 5 and Figure 9 As shown, there are at least two second edge-sealing portions 230, and the two second edge-sealing portions 230 are respectively disposed on both sides of the three-dimensional fabric 100.

[0052] In this embodiment, two second edge-sealing portions 230 are respectively disposed on both sides of the three-dimensional fabric 100, so that the edge-sealing fabric 200 can simultaneously cover the windward side 112 and the leeward side 122 of the three-dimensional fabric 100, thereby expanding the wrapping range of the edge-sealing fabric 200 on the outer end of the three-dimensional fabric 100, enabling the edge-sealing fabric 200 to simultaneously support both sides of the three-dimensional fabric 100, and improving the support strength and support effect of the edge-sealing fabric 200 on the three-dimensional fabric 100.

[0053] In some embodiments provided in this application, such as Figure 9 As shown, the shape of the liquid guide hole 210 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.

[0054] In this embodiment, the liquid guiding hole 210 can be a circular through hole or a polygonal through hole. When the liquid guiding hole 210 is a circular through hole, the diameter of the circle is less than or equal to 5 mm. When the liquid guiding hole 210 is a polygonal through hole, the longest diagonal of the polygon is less than or equal to 5 mm, and 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.

[0055] By limiting the size of the liquid guiding hole 210, the opening of the liquid guiding hole 210 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 210, making it easier for the liquid to form a convex liquid surface within the liquid guiding hole 210. This increases the surface energy of the liquid, making it easier for the liquid to penetrate the edge-sealing fabric 200. This improves the efficiency of liquid penetration into the edge-sealing fabric 200, thereby improving the efficiency of the edge-sealing fabric 200 in guiding liquid flow to the three-dimensional fabric 100, and further enhancing the humidification performance of the absorbent component 10.

[0056] In some embodiments provided in this application, such as Figure 5 As shown, the edge-sealing fabric 200 covers the three-dimensional fabric 100 in the second direction for a length of 1cm to 3cm.

[0057] In this embodiment, Figure 5In the second direction, F represents the coverage length of the edge-sealing fabric 200. By limiting the length of the edge-sealing fabric 200 in the second direction, the coverage range of the edge-sealing fabric 200 on the outer edge of the three-dimensional fabric 100 is limited. This allows the edge-sealing fabric 200 to extend to a position 1cm to 3cm away from the end face on the windward side 112 or leeward side 122 of the three-dimensional fabric 100. This ensures that the coverage range of the edge-sealing fabric 200 is within a reasonable range, preventing the edge-sealing fabric 200 from having too small a coverage range, which would result in weak support strength, and also preventing the edge-sealing fabric 200 from having too large a coverage range, which would affect the contact between the three-dimensional fabric 100 and airflow and water flow.

[0058] In some embodiments provided in this application, such as Figure 5 As shown, the distance between the two end faces of the three-dimensional fabric 100 along the first direction is H1, and the thickness of the first edge sealing portion 220 and the second edge sealing portion 230 is H2, where H2≤0.2H1 and / or H2≤2mm.

[0059] In this embodiment, the distance between the windward side 112 and the leeward side 122 of the three-dimensional fabric 100 is H1, and the thickness of the first edge sealing portion 220 and the second edge sealing portion 230 is the same, both being H2. By limiting the thickness of the edge sealing fabric 200, the edge sealing fabric 200 is made relatively thin, which improves the air permeability and permeability of the edge sealing fabric 200, thereby improving the humidification effect of the water absorption component 10.

[0060] In some embodiments provided in this application, such as Figure 10 As shown, the edge sealing fabric 200 has a multi-layer structure, including a first fabric 240 and a second fabric 250 stacked together, with the first fabric 240 covering the outside of the second fabric 250.

[0061] In this embodiment, the first fabric 240 and the second fabric 250 are stacked, with the first fabric 240 covering the outside of the second fabric 250, so that the edge sealing fabric 200 forms a multi-layer structure. The first fabric 240 and the second fabric 250 together wrap the outer end of the three-dimensional fabric 100, which improves the overall structural strength of the edge sealing fabric 200, thereby improving the support effect of the edge sealing fabric 200 on the three-dimensional fabric 100 and improving the stability of the water absorption component 10.

[0062] In some embodiments provided in this application, such as Figure 10 As shown, the edge-sealing fabric 200 also includes: a first connecting fiber 260, the two ends of which are respectively connected to the first fabric 240 and the second fabric 250.

[0063] In this embodiment, the multi-layered feature of the edge-sealing fabric 200 is further defined, and the number of first connecting fibers 260 can be multiple. The first connecting fibers 260 are located between the first fabric 240 and the second fabric 250, and the first fabric 240 and the second fabric 250 are connected by the first connecting fibers 260, which further improves the structural strength of the edge-sealing fabric 200, thereby improving the support effect of the edge-sealing fabric 200 on the three-dimensional fabric 100 and improving the stability of the absorbent component 10. Furthermore, the first connecting fibers 260 can store and guide the liquid flowing through the first fabric 240, improving the liquid guiding efficiency and seepage uniformity of the edge-sealing fabric 200.

[0064] In some embodiments provided in this application, such as Figure 10 As shown, the first fabric 240 is provided with a first through hole 241, and the second fabric 250 is provided with a second through hole 251. The shapes of the first through hole 241 and the second through hole 251 include circles or polygons. The diameter or the longest diagonal length of the first through hole 241 is D1, and the diameter or the longest diagonal length of the second through hole 251 is D2, where D1 ≥ D2.

[0065] In this embodiment, the multi-layered features of the edge-sealing fabric 200 are further defined. The liquid guiding hole 210 of the first fabric 240 is a first through hole 241, and the liquid guiding hole 210 of the second fabric 250 is a second through hole 251. The first through hole 241 and the second through hole 251 can be circular or polygonal through holes. The diameter or longest diagonal length of the first through hole 241 is D1, and the diameter or longest diagonal length of the second through hole 251 is D2, where D1≥D2. This makes the opening size of the first through hole 241 greater than or equal to the opening size of the second through hole 251, 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 200 and preventing liquid from accumulating inside the edge-sealing fabric 200.

[0066] In some embodiments provided in this application, D1 is 8 to 12 times D2.

[0067] In this embodiment, the opening size of the sealing fabric 200 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 210 of each layer of the multi-layer sealing fabric 200 within a reasonable range, the opening size of the first through hole 241 is much larger than the opening size of the second through hole 251, 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 200.

[0068] In some embodiments provided in this application, there are multiple three-dimensional fabrics 100, which are stacked and the edge-sealing fabric 200 covers the ends of the multiple three-dimensional fabrics 100.

[0069] In this embodiment, multiple three-dimensional fabrics 100 are stacked, forming a multi-layered structure that improves the water absorption and evaporation effects of the absorbent component 10. The edge-sealing fabric 200, by wrapping the ends of the multiple three-dimensional fabrics 100, effectively seals the edges, reducing the number of edge-sealing fabrics 200 required. Furthermore, the multiple three-dimensional fabrics 100 are connected by the edge-sealing fabric 200, improving the overall structural strength and morphological stability of the multiple three-dimensional fabrics 100. Simultaneously, the edge-sealing fabric 200 guides liquid to the ends of the multiple three-dimensional fabrics 100, improving the uniformity of liquid permeation.

[0070] For example, the number of three-dimensional fabrics 100 can be 4 to 6.

[0071] In some embodiments provided in this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the three-dimensional fabric 100 includes: a first substrate 110, a second substrate 120, and a second connecting fiber 130. The first substrate 110 is provided with a first ventilation hole 111. The second substrate 120 is spaced apart from the first substrate 110 along a first direction and is provided with a second ventilation hole 121. The second connecting fiber 130 connects the first substrate 110 and the second substrate 120 respectively.

[0072] In this embodiment, the structure of the three-dimensional fabric 100 is defined. A first substrate 110 and a second substrate 120 are disposed opposite to each other, with a windward side 112 and a leeward side 122 respectively disposed on the first substrate 110 and the second substrate 120. A first vent 111 and a second vent 121 are connected, forming an airflow passage, allowing airflow to enter through the first vent 111 and exit through the second vent 121. A second connecting fiber 130 is located between the first substrate 110 and the second substrate 120, connecting them, thus forming a three-dimensional structure for the three-dimensional fabric 100.

[0073] In one embodiment, there are multiple second connecting fibers 130, and any one of the second connecting fibers 130 is connected to the first substrate 110 and the second substrate 120 respectively.

[0074] In another embodiment, there is one second connecting fiber 130, which continuously passes through the plurality of first vent holes 111 and the plurality of second vent holes 121.

[0075] The second connecting fiber 130 can absorb liquid or allow liquid to adhere to its surface, increasing the surface area of ​​the three-dimensional fabric 100. This improves the liquid adsorption efficiency of the three-dimensional fabric 100, thereby enhancing its water absorption and evaporation effects. Furthermore, during the evaporation process, scale easily precipitates on the three-dimensional fabric 100. This three-dimensional structure improves the water retention and air permeability of the three-dimensional fabric 100, thus preventing scale from reducing its humidification capacity.

[0076] For example, the materials of the first substrate 110 and the second substrate 120 can be at least one of natural fibers, metal fibers or resin fibers, and the material of the second connecting fiber 130 can be a resin material.

[0077] In some embodiments provided in this application, such as Figure 6 and Figure 8 As shown, the shapes of the first vent 111 and the second vent 121 include circles or polygons, with the diameter of the circle or the longest diagonal of the polygon being greater than or equal to 2 mm.

[0078] In this embodiment, when the first vent 111 and the second vent 121 are circular through holes, the diameter of the circle is less than or equal to 2 mm. When the first vent 111 and the second vent 121 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 vents on the three-dimensional fabric 100, 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 vent 111 and the second vent 121, improves the air permeability of the three-dimensional fabric 100, and thus improves the humidification effect of the three-dimensional fabric 100.

[0079] In some embodiments provided in this application, such as Figure 8 As shown, a plurality of second connecting fibers 130 form a connecting fiber group around the first vent 111, and the number of second connecting fibers 130 in the connecting fiber group is 4 to 50.

[0080] In this embodiment, the number of second connecting fibers 130 surrounding the first vent is limited. This allows liquid to adhere to the second connecting fibers 130 while also adhering to the gaps between adjacent second connecting fibers 130 through capillary action. This increases the amount of liquid adhering to the second connecting fibers 130 and improves the moisturizing effect of the three-dimensional fabric 100. Furthermore, it prevents an excessive number of second connecting fibers 130 from affecting airflow within the three-dimensional fabric 100.

[0081] A second aspect of this application provides a humidification device 20, such as Figure 11 As shown, the humidification device 20 includes: an air supply device 21 and a water absorption component 10 provided in any of the first aspects of the above embodiments, wherein the air supply device 21 and the water absorption component 10 are arranged opposite to each other.

[0082] In this embodiment, the airflow blown out by the air supply device 21 can pass through the water absorption component 10 and introduce the moisture on the water absorption component 10 into the airflow, thereby increasing the moisture content in the air and humidifying the air.

[0083] It should be noted that the humidification device 20 includes the water absorption component 10 provided in any of the above embodiments, and therefore has all the beneficial technical effects of the water absorption component 10.
