Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to an absorbent fabric, a water storage component, and a humidifier. Background Technology

[0002] The humidification performance of evaporative humidifiers is strongly correlated with the water absorption and ventilation properties of the absorbent fabric. Absorbent fabrics typically consist of two substrate layers and a connecting fiber in the middle. The connecting fiber weaves back and forth between the two substrate layers, forming a three-dimensional fabric. During humidification, the water supply component within the humidifier supplies water to the absorbent fabric, the water flow soaks into the fabric, and air, driven by the fan component, passes through and absorbs the fabric, thus achieving moisture evaporation.

[0003] However, the absorbent fabrics in related technologies typically employ a three-dimensional weaving method. Their structure includes upper and lower substrate layers and connecting fibers in between. The manufacturing process requires controlling multiple layers of weaving, making the process relatively complex. More importantly, because the connecting fibers also support the space between the upper and lower substrate layers, these fibers, constrained between the two layers, need to have a certain density. This often results in high airflow resistance in the absorbent fabric, limiting its moisture evaporation efficiency, thereby reducing the humidification performance of the humidifier and increasing its energy consumption. Utility Model Content

[0004] This application discloses an absorbent fabric, a water storage component, and a humidification device. The absorbent fabric, through its structure of a single-layer base and fiber threads arranged on one side, reduces the airflow resistance of the absorbent fabric while maintaining its water retention capacity.

[0005] In a first aspect, this application proposes an absorbent fabric comprising:

[0006] The base layer includes multiple mesh ports, each mesh port having an outline formed by wires having multiple through holes;

[0007] A fiber thread, which is connected to one of the thread holes and extends from the thread hole in a direction away from the base layer and bends back through the same thread hole, or is threaded through and connected to another thread hole.

[0008] In a possible implementation of the first aspect, the fiber thread forms a plurality of pile portions protruding from one side of the base layer by passing through and through the threading hole; the pile portions are rounded at the bent ends away from the base layer.

[0009] In a possible implementation of the first aspect, the end of the pile portion that passes through or enters each of the threading holes is a connection point, and the number of connection points on each of the threading holes is N, where N satisfies: 6≤N≤48.

[0010] In one possible implementation of the first aspect, the fiber thread is a continuous thread that is wound around the plurality of thread holes to form a plurality of end-to-end connected pile portions.

[0011] In one possible implementation of the first aspect, the plurality of said pile portions have the same or different extension lengths in a direction perpendicular to the base layer.

[0012] In one possible implementation of the first aspect, the difference in the extension length of at least two of the pile portions along the direction perpendicular to the base layer is H, where 1 mm ≤ H ≤ 3 mm.

[0013] In one possible implementation of the first aspect, the diameter of the fiber is D1, wherein 20D≤D1≤30D.

[0014] In one possible implementation of the first aspect, the base layer is woven from wire 103 having multiple loops, some of the loops are sleeved to form the mesh opening, and the threading holes are formed between adjacent loops.

[0015] Secondly, embodiments of this application provide a water storage device, including:

[0016] The water-absorbing fabric described in the first aspect of the application forms a water-retaining mesh fabric;

[0017] The water-storing mesh is formed by repeatedly bending or rolling a single layer of the absorbent fabric to form a layered structure, or the water-storing mesh is formed by stacking at least two independent layers of the absorbent fabric.

[0018] In a possible implementation of the second aspect, at least one pair of adjacent absorbent fabrics having pile portions are disposed opposite each other, and at least a portion of the pile portion of one of the two adjacent absorbent fabrics is in contact with at least a portion of the pile portion of the other absorbent fabric.

[0019] In a possible implementation of the second aspect, the pile portions of the two outermost layers of the absorbent fabric are arranged opposite each other.

[0020] In a possible implementation of the second aspect, the water storage mesh is constructed as a hollow cylinder, and the water storage component further includes a water guiding mesh covering the two axial ends of the water storage mesh.

[0021] Thirdly, this application also provides a humidification device, including:

[0022] The absorbent fabric provided in the first aspect of this application; or the water storage component provided in the second aspect of this application.

[0023] The absorbent fabric provided in this application embodiment has fibers connected to the thread holes of a single base layer. Since the fibers only need to be wound around a single base layer, the arrangement of the fibers is no longer constrained by another substrate layer, allowing for optimized adjustment of the gaps between the fibers. This reduces the obstruction of the airflow channel by the fibers and lowers the wind resistance of the absorbent fabric. Simultaneously, the suspended structure formed by the fibers extending and bending away from the base layer has a larger surface area for the same projected area, allowing airflow to contact more of the moist fiber surface, thereby improving the moisture evaporation efficiency of the absorbent fabric. Furthermore, the portion of the fibers suspended on the other side of the base layer can undergo slight deformation under airflow impact. When the airflow pressure is high, the fibers can shift, temporarily enlarging the airflow channel to reduce resistance. When the airflow pressure is low, the fibers spring back, allowing the absorbent fabric to adapt to different airflow conditions, which is beneficial for the stability of the humidification effect.

Detailed Implementation

[0035] 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.

[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0040] In evaporative humidifiers, the key to humidification efficiency lies in whether the absorbent fabric can efficiently store water while providing a smooth channel for air circulation. The absorbent fabrics in related technologies typically employ a three-dimensional weaving method, consisting of two supporting substrate layers and connecting fibers that interweave repeatedly, thus forming a three-dimensional space that accommodates both moisture and air. During humidification, water is supplied to the absorbent fabric to wet it. Subsequently, under the action of a fan assembly, air penetrates the internal structure of the absorbent fabric, exchanging heat and moisture with the moisture on the surface of the wet fibers, thereby achieving the purpose of humidification.

[0041] However, the structure of absorbent fabrics, which uses two layers of substrate to hold connecting fibers, requires controlled multi-layer weaving during manufacturing, making the process relatively complex. The weaving process necessitates controlling the path of the connecting fibers through the upper and lower substrate layers. A deeper issue lies in the fact that the connecting fibers, tightly bound between the two substrate layers, not only retain water but also provide support. Therefore, the density of these connecting fibers is often high, which can reduce the airflow through the microscopic airflow channels within the absorbent fabric, increasing airflow resistance.

[0042] Furthermore, since the connecting fibers link the upper and lower substrates, the deformability of the connecting fibers will be exacerbated when either substrate deforms, increasing the instability of the airflow channels and making it easier for a continuous water film to form in the gaps between the connecting fibers. This water film will further block the airflow channels, increasing airflow resistance.

[0043] Based on this, this application provides a water-absorbing fabric with a base layer, so the fiber yarns do not need to bear the supporting role, thus the density of the fiber yarns is more controllable, reducing the risk of excessive wind resistance of the water-absorbing fabric in a wet state, thereby improving the humidification performance of the water-absorbing fabric.

[0044] like Figures 1 to 3 As shown, this application embodiment provides an absorbent fabric 1, which can be used as a wet curtain in a humidifying device 3. When the humidifying device 3 is working, the water supply component 302 supplies water to the absorbent fabric 1 to keep it moist. The airflow driven by the fan component 301 passes through the moist absorbent fabric 1, and the water evaporates under the action of the airflow and enters the indoor environment with the airflow, thereby achieving air humidification.

[0045] like Figure 1 As shown, the absorbent fabric 1 includes a base layer 10. The base layer 10 is formed from yarns 103 through a weaving process. The base layer 10 has an overall mesh structure, with multiple arrayed mesh openings 101 distributed on it. These mesh openings 101 are enclosed by the woven yarns 103 and are used to allow airflow. It can be understood that each mesh opening 101 defines a three-dimensional airflow channel in a direction perpendicular to the base layer 10.

[0046] The material of the thread 103 can be synthetic materials such as PET (polyethylene terephthalate), PP (polypropylene), PA (polyamide), PAN (polyacrylonitrile), PTT (polypropylene terephthalate), or PBT (polybutylene terephthalate). The thread 103 constituting the base layer 10 mainly serves as the skeleton of the absorbent fabric 1, retains moisture, and maintains the structural stability of the absorbent fabric 1.

[0047] In practical applications, yarn 103 can be selected from yarns made of multiple microfibers twisted together (e.g., 144F / 150D). D (Denier) represents the total fineness of the yarn, reflecting the overall thickness of the yarn, while F indicates that the yarn is composed of F (144) independent monofilaments. This type of yarn has a large number of monofilaments and a large specific surface area, which helps to improve the hydrophilicity and water retention capacity of the base layer 10 itself. Yarn 103 can also be selected from yarns made of a few coarser fibers twisted together (e.g., 12F / 100D), thereby improving the strength and stiffness of the absorbent fabric 1 structure.

[0048] The wire 103 includes multiple wire loops 102. The wire loops 102 are interconnected to form a stable mesh skeleton of the base layer 10. Specifically, some of the wire loops 102 are joined together to form mesh openings 101.

[0049] The wire 103 has multiple through holes 1021. Specifically, through holes 1021 are formed between adjacent loops 102. The through holes 1021 are formed by the loops 102 passing through each other, with one loop 102 occupying a portion of the space within the other loop 102. The space between two adjacent loops 102 is called a through hole 1021. Alternatively, it can be said that the through hole 1021 is the gap formed by the interlacing of adjacent loops 102; that is, the through hole 1021 is actually a cavity formed by the intersection of two loops 102.

[0050] like Figure 1 As shown, the absorbent fabric 1 also includes fiber threads 20. The fiber threads 20 are wound around the wires 103 that form the outline of the mesh opening 101. Specifically, the fiber threads 20 are connected to a thread hole 1021 and extend from this thread hole 1021 in a direction away from the base layer 10. After bending in the air, their ends either return to the same thread hole 1021 or pass through and connect to another thread hole 1021. Through this winding method, the fiber threads 20 form multiple suspended fiber rings or fiber arch structures protruding from the surface of the base layer 10 on one side of the base layer 10.

[0051] like Figure 1 and Figure 2 As shown, the fiber thread 20 emerges from a thread hole 1021, extends away from the base layer 10, bends, and then enters the same thread hole 1021 or another thread hole 1021.

[0052] Specifically, the fiber 20 passes through a thread hole 1021 from one side of the base layer 10 to the other side of the base layer 10. Subsequently, the fiber 20 does not run close to the surface of the base layer 10, but extends a distance away from the surface of the base layer 10 to form a raised fiber segment. This fiber segment bends in the air and eventually passes back into the base layer 10.

[0053] It should be noted that there are two possibilities for the "other threading hole 1021" through which the fiber thread 20 passes: First, this "other threading hole 1021" and the initial threading hole 1021 through which the fiber thread 20 passes are located on the same mesh opening 101 outline; second, the "other threading hole 1021" and the initial threading hole 1021 through which the fiber thread 20 passes belong to two different mesh openings 101. In this way, the fiber thread 20 can repeatedly wind around among multiple mesh openings 101 of the base layer 10, forming a three-dimensional fiber network covering the surface of the base layer 10. It is understandable that in the absorbent fabric of the related double-layer substrate, the close arrangement of connecting fibers that provide support results in dense connecting fibers and the easy formation of a water film between the connecting fibers. This water film will crowd out the ventilation area of ​​the airflow channel, thereby increasing the wind resistance of the absorbent fabric. In the absorbent fabric 1 provided in this application, since the fiber threads 20 protrude independently on the stable single-layer base layer 10, the gaps in the fiber rings or fiber arch structures generated by the winding of the fiber threads are controlled, thereby reducing the risk of forming a continuous water film due to the aggregation of fiber threads 20, which helps to maintain the smooth flow of airflow channels and control the wind resistance of the absorbent fabric 1.

[0054] Specifically, the structure of the fiber thread 20 winding around the single-layer base layer 10 reduces the complexity of the weaving process required in related technologies, which necessitates weaving connecting fibers between the upper and lower substrates. Simultaneously, the use of a single-layer base layer reduces the risk of the connecting fibers being constrained between two substrates, where the tightness and arrangement of the connecting fibers are jointly restricted by both substrates, potentially leading to an overly dense arrangement of connecting fibers. In contrast, the fiber thread 20 in the absorbent fabric 1 of this application is wound around the wire 103 constituting the mesh opening 101 of the single base layer 10. The winding method and density of the fiber thread 20 do not need to consider the support requirements of the other base layer 10, and therefore can be independently optimized according to water retention and ventilation needs.

[0055] The fiber thread 20 can also be made of the aforementioned synthetic materials such as PET, PP, and PA. Since the fiber thread 20 needs to protrude from the surface of the base layer 10 and maintain a certain morphological stability in the airflow to retain water, it must possess sufficient stiffness and elasticity. Therefore, the fiber thread 20 can be selected with a higher linear density; for example, it can be a monofilament or yarn with a linear density of not less than 20D (20 grams per 9000 meters of fiber). This helps prevent the formed fiber thread 20 from collapsing in a wet state, maintaining a fluffy structure, thereby ensuring the contact area between the fiber thread 20 and the airflow and a stable water evaporation efficiency.

[0056] Thus, in the embodiment of this application, the absorbent fabric 1, with its fiber threads 20 connected to the thread holes 1021 of a single base layer 10, only needs to be wound around a single layer of base layer 10. The arrangement of the fiber threads 20 is no longer constrained by another layer of substrate, allowing for optimized adjustment of the gaps between the fiber threads 20. This reduces the obstruction of the airflow channel by the fiber threads 20 and lowers the wind resistance of the absorbent fabric 1. Simultaneously, the suspended structure formed by the fiber threads 20 extending and bending away from the base layer 10 has a larger surface area for the same projected area, allowing airflow to contact more of the moistened fiber thread 20 surface, thereby improving the moisture evaporation efficiency of the absorbent fabric 1. Furthermore, the suspended structure of the fiber threads 20 can undergo slight deformation under airflow impact. When the airflow pressure is high, the fiber threads 20 can be bent, temporarily enlarging the airflow channel to reduce resistance. When the airflow pressure is low, the fiber threads 20 spring back, allowing the absorbent fabric 1 to adapt to different airflow conditions, which is beneficial for the stability of the humidification effect.

[0057] In some embodiments, such as Figures 1 to 3 As shown, the fiber thread 20 forms multiple outwardly protruding pile portions 201 on one side (e.g., the leeward side) of the base layer 10, which are the aforementioned fiber ring or fiber arch structure. Both ends of each pile portion 201 are connected to or woven into the thread 103 at the edge of the mesh opening 101, causing the pile portion 201 to bulge on the surface of the base layer 10, forming a fluffy fiber structure. Both ends of each pile portion 201 are connected to the same thread hole 1021 or different thread holes 1021. Different thread holes 1021 can be thread holes of the same mesh opening 101 or two thread holes 1021 on different mesh openings 101.

[0058] The fiber thread 20's "exit-extension-bend-entry" routing creates a three-dimensional fiber ring or arch structure on the surface of the base layer 10, with both ends fixed to the base layer 10 and the middle part suspended, which is the pile body 201. Compared to a straight fiber connected to the base layer 10, the ring or arch structure of the pile body 201 can accommodate more static air and moisture, and also has greater structural stability. At the same time, it provides a larger specific surface area for moisture adhesion.

[0059] The end of the fiber thread 20 can be threaded back into the same thread hole 1021 from which it initially emerged for fixation. This helps to appropriately increase the density of the pile portion 201. Alternatively, the end of the fiber thread 20 can also be threaded into another thread hole 1021 adjacent to the initial thread hole 1021 for fixation. This increases the coverage area of ​​the pile portion 201, forming a pile portion 201 between the two thread holes 1021, which helps to create a fluffier pile structure with a larger distribution area.

[0060] Meanwhile, since both ends of the pile body 201 are connected to the thread hole 1021 formed by the interlacing of the thread loops 102, the pile body 201 can maintain its ring-shaped or arched structure during use, thus ensuring the structural stability of the pile body 201.

[0061] In some embodiments, the portion of the fiber filament 20 that bends in the air is deflected in the horizontal direction. Thus, the projection of the bent portion along the direction perpendicular to the base layer 10 falls at least partially into the opening area defined by the edge of the mesh 101.

[0062] It should be noted that there are two situations where at least a portion of the projection of the pile portion 201 along the direction perpendicular to the base layer 10 falls into the opening area of ​​the mesh opening 101: First, at least a portion of the projection of the pile portion 201 can fall into the opening area of ​​the initial mesh opening 101 through which the fiber thread 20 passes; second, at least a portion of the projection of the pile portion 201 can also fall into the opening area of ​​the adjacent mesh opening 101. For example... Figure 2 and Figure 3 As shown, when viewed along a direction perpendicular to the base layer 10 (i.e., the Z direction in the figure), the projection of at least a portion of one or more of the pile portions 201 falls within the space defined by the edge wires 103 of the mesh opening 101. This means that, viewed from a perspective perpendicular to the base layer 10, the protruding pile portions 201 will obstruct the three-dimensional airflow channels of the mesh opening 101 extending from them.

[0063] It is understood that the pile portion 201 is composed of fine fiber threads 20 and has good hydrophilicity, thereby increasing the contact area between the absorbent fabric 1 and the airflow. Specifically, when the pile portion 201 is projected in a direction perpendicular to the base layer 10, if at least a portion of the pile portion 201's projection is located inside the mesh opening 101, it means that these fluffy fiber structures extend into the airflow channels formed by the mesh opening 101 to a certain extent. When the airflow passes through the mesh opening 101, the airflow will come into full contact with the pile portion 201 extending into the airflow channels. Since the surface of the pile portion 201 is covered with moisture, the contact area between the airflow and the liquid is increased, thereby improving the efficiency of moisture evaporation.

[0064] It is understandable that if water retention and humidification rely solely on the mesh openings 101 of the base layer 10, the air-liquid contact area of ​​the absorbent fabric 1 is limited. In this embodiment, by providing a pile portion 201 that protrudes from the base layer 10 and is at least partially projected within the mesh openings 101, the pile portion 201, with its excellent water-retention fiber surface, allows airflow to more effectively remove moisture as it passes through the mesh openings 101, without significantly increasing the density of the base layer 10 itself.

[0065] Under normal conditions, the protruding shape of the pile portion 201 allows it to extend directly into the three-dimensional airflow channel defined by the mesh opening 101. When airflow passes through, it can fully contact these fluffy fiber structures filled with moisture, thereby effectively improving the moisture evaporation efficiency. Since the bent portion of the pile portion 201 is suspended and unrestrained, it possesses a certain degree of flexible deformation capability. When the airflow velocity increases and the wind pressure intensifies, the thrust of the airflow on the pile portion 201 also increases, which may cause the pile portion 201 to undergo moderate elastic deformation, deflecting away from the airflow. This is equivalent to temporarily increasing the effective ventilation area of ​​the mesh opening 101 at that location, reducing the instantaneous resistance of the airflow passing through the mesh opening 101.

[0066] Conversely, when the airflow pressure decreases, the pile portion 201 recovers to a fluffy state due to its own elasticity, reoccupies part of the airflow channel to maintain a high evaporation area. In this way, the pile portion 201 can adaptively deform according to the strength of the airflow, so that the absorbent fabric 1 can achieve a dynamic balance between "high evaporation efficiency" and "low ventilation resistance", which is especially helpful in reducing the energy consumption of the humidifier 3 under high airflow conditions.

[0067] Thus, the absorbent fabric 1 provided in this application embodiment provides a fiber thread 20 on the base layer 10 woven from the thread 103, and forms a plurality of pile portions 201 on one side of the base layer 10, with the projection of some pile portions 201 located within the mesh opening 101. This increases the surface area of ​​the fibers used for water retention outside the base material woven from the thread 103, improves the humidification capacity of the absorbent fabric 1, and maintains the structural stability and durability of the absorbent fabric 1.

[0068] In some embodiments, such as Figure 1 As shown, the fiber thread 20 is a continuous thread. The fiber thread 20 is wound through multiple thread holes 1021 to form multiple pile portions 201 connected end to end.

[0069] Specifically, the continuous fiber thread 20 can sequentially pass through different threading holes 1021 on the base layer 10 according to a preset path. After the fiber thread 20 exits from one threading hole 1021 and forms the first pile portion 201, it is not cut off, but continues to extend to the next target threading hole 1021 to perform the operations of exiting, bending, and entering, thereby forming the second pile portion 201. This process is repeated until a series of multiple pile portions 201 composed of the same fiber thread 20 and structurally connected end to end are formed.

[0070] It should be noted that a continuous thread does not necessarily refer to an uninterrupted single fiber. In actual production processes, fiber threads 20 can be connected by methods such as knotting, splicing, and melt bonding to form a continuous thread in appearance.

[0071] Thus, the continuous winding path of the fiber thread 20 makes the stress distribution more uniform between the pile body 201. When the absorbent fabric 1 is pulled by an external force, the stress can be continuously transmitted along the fiber thread 20, avoiding local stress concentration, thereby improving the durability and morphological stability of the absorbent fabric 1 in a wet state.

[0072] In some embodiments, the end of the pile portion 201 that passes through or through each thread hole 1021 is a connection point. The number of connection points on each thread hole 1021 is N, where N satisfies: 6 ≤ N ≤ 48.

[0073] The number of connection points N is a key parameter determining the structural strength and ventilation / water permeability of the mesh opening 101. A connection point refers to a physical connection point where the fiber thread 20 passes through the mesh opening 101 to the outside of the base layer 10 or back to the inside of the mesh opening 101 during the winding process. Each connection point signifies one interweaving or connection between the fiber thread 20 and the base layer 10 wires 103 constituting the mesh opening 101. In other words, for any threading hole 1021, N is the sum of the number of all the exit and entry ends of the pile portion 201 on that threading hole 1021.

[0074] When N < 6, it indicates that there are fewer ends of the fiber threads 20 connected to a single thread hole 1021. This not only leads to insufficient structural strength at the thread hole 1021, but also makes the multiple pile parts 201 formed at the thread hole 1021 less stable. When subjected to strong airflow impact, the relatively sparse pile parts 201 are more prone to large swings, displacements, or even being completely blown out of the airflow channel due to the lack of mutual traction and support between adjacent pile parts 201, thereby reducing the gas-liquid contact area of ​​the absorbent fabric 1.

[0075] When N > 48, the ends of multiple fiber threads 20 are densely packed at a single threading hole 1021, causing excessive crowding of the fiber threads 20. Although the clustering of the pile portions 201 formed by the fiber threads 20 makes it less likely for individual pile portions 201 to be blown away, the excessively high fiber density will hinder the capillary penetration and diffusion of water at the mesh opening 101 and reduce the effective ventilation area of ​​the airflow channel, resulting in increased airflow resistance of the absorbent fabric 1.

[0076] Thus, by controlling the value of N within the range of 6 to 48, the structural strength, wetting properties, and ventilation efficiency of the absorbent fabric 1 can be balanced. This ensures that the pile portion 201 has sufficient link strength and cluster stability to resist airflow impact, while also reducing the adverse effects of excessively dense fibers on water permeability and ventilation.

[0077] In some embodiments, the pile portion 201 extends and bends in a direction away from the base layer 10, and its bent end away from the base layer 10 has a natural rounded shape.

[0078] After the fiber thread 20 exits the threading hole 1021 and before it bends and re-enters, it can maintain a certain amount of slack. This slack allows the fiber thread 20 to bend naturally under its own elasticity, thus forming a smooth, continuous, rounded bend end, rather than a sharp angle.

[0079] The smooth end shape of the flocked portion 201 helps reduce local stress concentration, thereby improving the flocked portion 201's resistance to airflow erosion and mechanical fatigue, and enhancing its durability. At the same time, the smooth surface of the bent end of the flocked portion 201 is also more conducive to the uniform adhesion and maintenance of the water film, which helps to maintain and improve the gas-liquid exchange efficiency.

[0080] In some embodiments, such as Figure 1 and Figure 2 As shown, multiple pile bodies 201 have the same extension length in a direction perpendicular to the base layer 10.

[0081] It is understood that when the fiber thread 20 is wound to form each pile portion 201, its length extending from the thread hole 1021 is kept consistent. This results in the multiple pile portions 201 that are ultimately formed having a relatively uniform height in the direction perpendicular to the base layer 10, forming a flat and regular three-dimensional fiber layer.

[0082] Thus, the multiple pile portions 201 with uniform height ensure consistent water absorption performance throughout the absorbent fabric 1. Furthermore, the relatively balanced height of the pile portions 201 makes airflow through the absorbent fabric 1 more stable and smooth, reducing additional wind resistance caused by abrupt changes in local structure. The neatly arranged pile portions 201 facilitate uniform moisture distribution and evaporation, thereby simplifying the production process and improving the reliability and economy of the absorbent fabric while maintaining its high-efficiency humidification.

[0083] In some embodiments, such as Figure 4 As shown, the multiple pile bodies 201 have different extension lengths in the direction perpendicular to the base layer 10.

[0084] It can be understood that by controlling the length of the fiber thread 20 extending from the thread hole 1021 after being threaded but before being bent, the extension length of the formed pile portion 201 in the direction perpendicular to the base layer 10 can be controlled. During weaving, different pile portions 201 can have different extension lengths, either regularly or randomly.

[0085] In this way, multiple pile portions 201 form a staggered structure. The longer pile portions 201 can extend deeper into the airflow channel, while the shorter pile portions 201 are used to make gas-liquid contact with the airflow at the edge area of ​​the airflow channel. This staggered structure further increases the effective contact area and contact time between the airflow and the wet fiber threads 20, thereby improving the overall evaporation efficiency of the absorbent fabric 1.

[0086] Furthermore, the staggered distribution of the pile portions 201 allows the shorter pile portions 201 to form a support layer on the surface of the base layer 10. The shorter pile portions 201 can provide lateral support for the adjacent, taller pile portions 201. When the taller pile portions 201 sway or shift under the impact of airflow, the shorter pile portions 201 around the taller pile portions 201 can suppress excessive swaying of the taller pile portions 201 through contact and interaction, thereby improving the structural stability of the entire pile portion array 201 in dynamic airflow.

[0087] In some embodiments, the difference in extension length of at least two pile portions 201 along the direction perpendicular to the base layer 10 is H, where 1mm≤H≤3mm.

[0088] When H < 1 mm, the height difference between the pile parts 201 is too small, and they are almost on the same height plane, making it difficult to form an effective three-dimensional layer. The structural support effect of the shorter pile parts 201 on the longer pile parts 201 is not obvious.

[0089] When H>3mm, an excessive height difference between the pile parts 201 may cause the longer pile parts 201 to shift more under the impact of airflow, resulting in decreased stability.

[0090] In this way, the height difference H between the taller pile portion 201 and the shorter pile portion 201 is controlled within the range of 1mm to 3mm. This not only forms a staggered structure to increase the gas-liquid exchange area, but also allows the shorter pile portion 201 to provide effective lateral support to the taller pile portion 201, suppressing excessive swaying of the taller pile portion 201 in the airflow, thus jointly improving the efficiency and stability of moisture evaporation of the absorbent fabric 1.

[0091] In some embodiments, such as Figure 3 As shown, at least two pile bodies 201 overlap each other on one side of the base layer 10.

[0092] The overlapping of the pile portions 201 can form a more continuous water-retaining network. When water flows and wets the base layer 10, the moisture can be transferred and distributed more quickly between the pile portions 201 through the overlapping pile portions 201, which helps to reduce the occurrence of local dry areas and improve the wetting uniformity of the absorbent fabric 1.

[0093] Furthermore, when subjected to airflow impact, the force acting on a single pile part 201 can be distributed and transmitted to adjacent pile parts 201 through the overlap point, thereby effectively suppressing the large swaying of a single pile part 201 and enhancing the overall structural stability and deformation resistance of multiple pile parts 201 in dynamic airflow.

[0094] In some embodiments, the diameter of the fiber filament 20 is D1, wherein 20D≤D1≤30D.

[0095] When D1 < 20D, the fiber filaments 20 are too thin, which will result in insufficient rigidity. The resulting pile body 201 will be difficult to maintain its fluffy three-dimensional shape after wetting and will easily collapse under the gravity of the water flow, resulting in a reduction in the gas-liquid contact area and affecting the evaporation efficiency.

[0096] When D1 > 30D, the fiber yarn 20 becomes too coarse and stiff, reducing its flexibility. A stiffer fiber yarn 20 may increase the difficulty of the weaving process and make it difficult to form a smooth, natural bend at the end of the pile portion 201, which will weaken the capillary water-holding capacity of the pile portion 201 to some extent.

[0097] In this way, the diameter D1 of the fiber filament 20 is controlled within the range of 20D to 30D (20 grams for every 9000 meters of fiber). Within this range, the fiber filament 20 can maintain the shape stability of the pile portion 201 in a wet state with sufficient rigidity, and also has good processability to form smooth bending ends, thereby enabling the absorbent fabric 1 to obtain continuous and efficient humidification performance.

[0098] like Figure 5 and Figure 6As shown, an embodiment of the second aspect of this application also provides a water storage component 2, which includes a water-absorbing mesh 30 formed of an absorbent fabric 1. The absorbent fabric 1 is the absorbent fabric 1 provided in any of the above embodiments of this application, and its beneficial effects have been described in detail in the above embodiments, and will not be repeated here.

[0099] The water-retaining mesh 30 can be formed by repeatedly bending or rolling a single layer of absorbent fabric 1 to form a layered structure. Alternatively, the water-retaining mesh 30 can be formed by stacking at least two independent layers of absorbent fabric 1.

[0100] Specifically, in one implementation, a single layer of absorbent fabric 1 can be continuously bent in a "Z" shape to stack it into a multi-layered water-retaining mesh fabric 30. This one-piece molded water-retaining mesh fabric 30 has a coherent structure and strong integrity.

[0101] In another implementation, a single layer of absorbent fabric 1 can be spirally wound around a central axis to form a multi-layered water storage mesh 30, thereby maximizing the evaporation area of ​​the water storage mesh 30 within a limited space.

[0102] In another implementation, the water-storing mesh 30 can also be formed by stacking and connecting at least two independent layers of absorbent fabric 1. The edges of the at least two layers of absorbent fabric 1 are connected to each other by at least one of sewing, bonding, or hot-melt welding, so that the multiple layers of absorbent fabric 1 can form a stacked structure in the stacking direction (i.e., the Z direction in the figure). The multiple layers of absorbent fabric 1 are integrated into a water-storing component 2 that is easy to install and disassemble as a whole, preventing the layers of absorbent fabric 1 from misaligning or separating during use.

[0103] Specifically, the edge refers to the annular area surrounding each layer of absorbent fabric 1.

[0104] In some embodiments, such as Figure 4 As shown, at least one pair of adjacent absorbent fabrics 1 with pile portion 201 are disposed opposite each other, and at least a portion of the pile portion 201 of one absorbent fabric 1 of the two adjacent absorbent fabrics 1 is in contact with at least a portion of the pile portion 201 of the other absorbent fabric 1.

[0105] When two layers of absorbent fabric 1 are stacked with their pile portions 201 facing each other, the pile portions 201 of the two layers of absorbent fabric 1 will abut against each other in the interlayer gap. The contact between the pile portions 201 allows the fiber networks of the two layers of absorbent fabric 1 to be interconnected in the stacking direction. Water can not only diffuse along the horizontal direction of a single layer of fabric, but also achieve rapid and even moisture transfer between the upper and lower base layers 10 through the contact points between the pile portions 201.

[0106] Thus, the contacting pile portions 201 form multiple elastic support points. These elastic support points can withstand pressure from the stacking direction, helping to maintain the structural stability of the water storage component 2 and preventing excessive pressure from affecting the ventilation channels.

[0107] Furthermore, the arrangement of the pile portions 201 of adjacent absorbent fabrics 1 in the water storage mesh 30 such that the base layer 10 of the absorbent fabric 1 (i.e., the opposite surface of the pile portion 201) faces outwards. The relatively flat and smooth surface of the base layer 10 facilitates the installation, fixing, and maintenance of the water storage component 2.

[0108] In some embodiments, the pile portions 201 of the two outermost layers of absorbent fabric 1 in at least two layers of absorbent fabric 1 are arranged opposite each other, that is, an internal water storage space is formed between the two outermost layers of absorbent fabric 1 in at least two layers of absorbent fabric 1, and the pile portions 201 of the outermost layers of absorbent fabric 1 are all located in the internal water storage space.

[0109] The pile portions 201 of the two outermost absorbent fabric pieces 1 are both oriented inwards. This allows the fluffy pile portions 201 to be encased within a water-storage space defined by the two base layers 10. The water-storage space constitutes the main water-storage area, where water flowing in can be effectively absorbed and retained by the pile portions 201. At the same time, the surface of the outer base layer 10 is relatively flat, facilitating the installation and fixation of the water-storage component 2.

[0110] When water flows into the water storage space, it is adsorbed and locked by the velvet body 201 through capillary action, reducing the probability of unnecessary water loss or rapid evaporation.

[0111] In some embodiments, when a pressure of 10 kPa is applied along the lamination direction of at least two layers of absorbent fabric 1, the thickness retention rate of the water storage component 2 is not less than 80%.

[0112] It is understandable that the thickness retention rate is an indicator for measuring the compressive strength of the water storage component 2. A thickness retention rate of not less than 80% indicates that when the water storage component 2 is subjected to pressure in a dry state, the velvet part 201 inside the water storage component 2 can effectively resist compression deformation and maintain the basic shape of the water storage component 2.

[0113] In some embodiments, the water-storing mesh 30 formed from the absorbent fabric 1 is configured as a hollow cylindrical structure. The water-guiding mesh 40 covers the axial ends of the water-storing mesh 30.

[0114] When the airflow passes through the cylindrical water storage mesh 30 along the axial direction, it comes into full contact with the water storage mesh 30, thereby causing gas-liquid exchange and the water inside the water storage mesh 30 evaporates.

[0115] like Figure 6As shown, the water guiding mesh 40 covers at least a portion of the outer end of the water storage mesh 30 along the axial direction of the water storage mesh 30, so that the water guiding mesh 40 covers at least a portion of the end face of the water storage mesh 30.

[0116] The water-guiding mesh 40 covers the end face of the water-storing mesh 30, thus fixing at least part of the edge of the water-storing mesh 30 and achieving an edge-sealing effect. The water-guiding mesh 40 provides structural support to the end of the water-storing mesh 30, improving the stability of its shape, reducing deformation or collapse, and ensuring sufficient contact area between the water-storing mesh 30 and airflow / water flow. This results in uniform local water absorption and ventilation, thereby improving the moisture retention and evaporation effects of the water-storing mesh 30. Since the structural shape of the water-storing mesh 30 is prone to gaps at the edges, the water-guiding mesh 40 can wrap around these edges, making the edges of the water-storing component 2 smoother, which helps increase the contact area between the water-storing component 2 and water, and improves its water-guiding effect.

[0117] In addition, the water-guiding mesh 40 has good air permeability and permeability. The liquid first contacts the water-guiding mesh 40 and then enters the water-storage mesh 30. When the liquid flows through the water-guiding mesh 40, it undergoes permeation and diffusion, which improves the uniformity of liquid distribution. This allows the water-guiding mesh 40 to play a role in uniformly distributing water to the water-storage mesh 30 below, thus optimizing the water absorption effect of the water-storage mesh 30.

[0118] The water-guiding mesh fabric 40 can be a single-layer porous substrate formed by a weaving process from synthetic fibers (such as polyester, nylon) or natural fibers (cotton yarn). The surface of the water-guiding mesh fabric 40 has regularly distributed geometric openings (such as regular hexagons or squares, with a diagonal of 2-12mm), and the mesh density is 5-30 meshes / cm. 2 .

[0119] like Figure 7 As shown, this application embodiment also provides a humidifying device 3, which may include the absorbent fabric 1 provided in any embodiment of the first aspect of this application, or the water storage component 2 provided in any embodiment of the second aspect of this application. The beneficial effects of the absorbent fabric 1 and the water storage component 2 provided in any embodiment of this application have been described in detail in the above embodiments, and will not be repeated here.

[0120] The humidifying device 3 includes a water supply component 300, which is used to deliver water to the absorbent fabric 1 or the water storage component 2.

[0121] The humidification device 3 also includes a fan assembly 301, which is used to agitate the airflow and make the airflow flow through the absorbent fabric 1 or the water storage component 2, so that the water on the water storage component 2 evaporates and flows with the airflow to the indoor environment, thereby humidifying the air.
