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] Evaporative humidifiers typically use three-dimensional mesh fabric as a water storage component. The three-dimensional mesh fabric can be made of two open base layers connected by a large number of connecting fibers. It uses the capillary action of the connecting fibers to store water and humidify the airflow.

[0003] However, the microstructure of the three-dimensional mesh fabric in related technologies is at risk of structural collapse. When the density of the connecting fibers in the three-dimensional mesh fabric is too high and the filament diameter is too thin, the capillary action between the connecting fibers will be too strong, causing the connecting fibers to stick together or become wetted by water. This will cause the three-dimensional mesh fabric to lose its support and collapse, affecting the reliability of the humidification device. Utility Model Content

[0004] This application discloses an absorbent fabric, a water storage component, and a humidification device. The absorbent fabric improves the sufficient gas-liquid contact area of ​​the absorbent fabric and reduces the risk of structural collapse caused by excessive capillary action by controlling the total circumferential area of ​​the connecting fibers within a unit area within an optimal range.

[0005] A first aspect of this application provides a water-absorbing fabric, the water-absorbing fabric comprising:

[0006] At least two base layers are provided, the at least two base layers are spaced apart, each of the at least two base layers includes multiple openings, and each opening is provided with multiple wire holes;

[0007] A connecting fiber is connected to two thread holes in two adjacent substrates to connect two openings located in the two substrates respectively;

[0008] Within a unit area of ​​one square inch located between two adjacent base layers and parallel to the base layers in a preset reference plane, the outline formed by the intersection of the connecting fiber and the preset reference plane has a preset total perimeter P, where P satisfies: 21.7mm≤P≤935.97mm.

[0009] In some possible implementations, the preset total perimeter P within a unit area of ​​one square inch satisfies: 43.3mm ≤ P ≤ 156mm.

[0010] In some possible implementations, the preset total perimeter P within a unit area of ​​one square inch satisfies: 77.9 mm ≤ P ≤ 130 mm.

[0011] In some possible implementations, the preset total circumference is directly proportional to the product of the diameter of the connecting fiber, the number of connecting fibers connected in the threading hole, the number of threading holes in the opening, and the number of openings.

[0012] In some possible implementations, the preset total perimeter P satisfies: P = (π × D) ×

[0013] (M×N×Q) / K; where D is the diameter of the connecting fiber, M is the number of threading holes in the opening, N is the number of connecting fibers connected in the threading holes, Q is the number of openings in a unit area, and K is a coefficient used to correct the repeated count of connecting fibers shared by adjacent openings.

[0014] In some possible implementations, M satisfies: 12 ≤ M ≤ 30.

[0015] In some possible implementations, N satisfies: 2 ≤ N ≤ 24.

[0016] In some possible implementations, D satisfies: 7μm≤D≤30μm.

[0017] In some possible implementations, Q satisfies: 25 / inch² ≤ Q ≤ 36 / inch².

[0018] In some possible implementations, K = 2.

[0019] In some possible implementations, the value of the number Q of the openings in the unit area is inversely correlated with the value of the number N of the connecting fibers connected in each of the threading holes.

[0020] In some possible implementations, N ≤ 4 when Q ≥ 30 / inch².

[0021] The second aspect of this application also provides a water storage device, the water storage device comprising: the absorbent fabric provided in the first aspect of this application, wherein at least two base layers of the absorbent fabric are arranged along the thickness direction of the absorbent fabric, and the absorbent fabric is formed into a tubular water storage mesh along the length direction of the at least two base layers; and a water-guiding fabric covering the two ends of the water storage mesh along its axial direction.

[0022] In some possible implementations, the height of the water storage mesh is H1, and the height of the water-guiding fabric along the axial direction of the water storage mesh is H2; wherein, H2≤0.2H1; and / or 1cm≤H2≤3cm.

[0023] A third aspect of this application also provides a humidification device, which includes the absorbent fabric provided in the first aspect of this application; or the water storage component provided in the second aspect of this application.

[0024] In some possible implementations, the humidification device further includes: a water supply device for supplying water to the water storage component; and a fan assembly for driving airflow through the water storage component, wherein the fan speed of the fan assembly is positively correlated with the preset total circumference P of the absorbent fabric of the water storage component.

[0025] The absorbent fabric 1 provided in this application achieves a balance between water retention capacity and structural stability by controlling the preset total perimeter of the connecting fibers within a unit area of ​​one square inch to the range of 21.7 mm to 935.97 mm. The preset total perimeter P meeting the above requirements provides sufficient peripheral area of ​​the connecting fibers to form a water film, thereby improving the water evaporation efficiency of the absorbent fabric. Simultaneously, the preset total perimeter meeting the above requirements also suppresses the adhesion of connecting fibers or structural collapse caused by excessive capillary action, helping to maintain the three-dimensional porous structure and support of the absorbent fabric 1, thereby improving the humidification function and service life of the absorbent fabric.

[0034] 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.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts.

Unless otherwise stated, "a plurality of" means two or more.

[0039] Evaporative humidifiers commonly use absorbent fabric as the humidifying filter. This absorbent fabric typically consists of a first layer with multiple openings and a second layer with multiple openings, connected by numerous connecting fibers to form an interconnected three-dimensional structure. During operation, a water supply device continuously supplies water to the absorbent fabric, utilizing the capillary action of the connecting fibers to retain the moisture. A fan assembly then drives airflow through the moistened absorbent fabric, causing the moisture to evaporate and achieving the humidification purpose.

[0040] In pursuit of higher humidification efficiency, some absorbent fabrics tend to use a combination of high fiber density and small filament diameter in their connecting fibers, significantly increasing the "total circumferential area" of the connecting fibers per unit area. Under these conditions, the capillary action between the connecting fibers becomes excessively strong, easily leading to a phenomenon known as "capillary flooding," where the connecting fibers stick together or become encased in water. "Capillary flooding" occurs when excessive capillary action of water fills the gaps between the connecting fibers, expelling air and causing the connecting fibers to lose their structural support. Once this happens, the three-dimensional structure of the absorbent fabric loses its support, causing the overall structure to collapse. This not only reduces the humidification performance of the absorbent fabric but also shortens its lifespan.

[0041] Based on this, this application proposes a water-absorbing fabric that, by controlling the preset total perimeter of the connecting fibers within a unit area of ​​one square inch within a reasonable range, not only increases the sufficient gas-liquid contact area of ​​the water-absorbing fabric, but also reduces the risk of structural collapse caused by excessive capillary action.

[0042] An embodiment of the first aspect of this application provides an absorbent fabric 1, which can be used to make a water storage component 2. The water storage component 2 can be applied to a humidification device 3 and used as a wet curtain in the humidification device 3. When the airflow disturbed by the fan in the humidification device 3 blows across the moist water storage component 2, the moisture on the water storage component 2 flows into the indoor environment with the airflow, thereby increasing the air humidity in the indoor environment.

[0043] Absorbent fabric 1 can be like Figure 1 The diagram shows two base layers 10, but it can also include three, four, or more base layers 10. The structures of any two base layers 10 can be identical or different. Multiple base layers 10 are stacked and spaced apart; the distance between the base layers 10 can be uniform or non-uniform.

[0044] The base layer 10 can be a fabric woven from yarn. The yarn includes multiple loops that are interlocked to form an opening 101. The base layer 10 may include multiple openings 101 for airflow. Threading holes 1011 are formed between adjacent loops. The interior of the opening 101 is hollow, and the edge contour of the opening 101 is a structure woven from the yarn. Adjacent openings 101 may share a portion of their edge contour. On the same base layer 10, the shape or area of ​​the openings 101 can be the same or different.

[0045] The connecting fiber 20 is a fiber with a certain rigidity that connects two base layers 10. The connecting fiber 20 maintains the distance between the base layers 10, which can be between 2mm and 5mm, to balance the structural strength of the absorbent fabric 1 and the length of the connecting fiber 20, thereby improving the structural support performance of the connecting fiber 20. The connecting fiber 20 extends from a threading hole 1011 in an opening 101 of one base layer 10 and extends into a threading hole 1011 of the opposite base layer 10 to connect two adjacent base layers 10.

[0046] Multiple connecting fibers 20 can be threaded through a single thread hole 1011. The connecting fibers 20 work together to connect and support the two base layers 10.

[0047] It should be noted that when the airflow passes between the two base layers 10, it will come into contact with the connecting fibers 20 between the base layers 10, and then with the moisture held by the connecting fibers 20, thus carrying away moisture, increasing the humidity of the airflow, and achieving the effect of humidifying the outside air. Therefore, the connecting fibers 20 not only support the adjacent base layers 10, but also affect the water holding capacity of the connecting fibers 20 and the degree of contact between the airflow and the connecting fibers 20, thereby affecting the water holding capacity of the absorbent fabric 1.

[0048] It is understandable that by appropriately increasing the number of connecting fibers 20 within a single threading hole 1011, the fiber density per unit area can be increased without altering the structure of the opening 101 in the base layer 10, thereby improving the water-holding capacity and evaporation efficiency of the connecting fibers 20. However, if the density of the connecting fibers 20 is too high, it will lead to excessively strong capillary action between the connecting fibers 20, which may cause problems such as fiber adhesion or structural collapse.

[0049] It should be noted that the connecting fiber 20 in the absorbent fabric 1 provided in this application embodiment is shared by adjacent openings 101. Specifically, the same connecting fiber 20 simultaneously serves as a boundary component of two or more adjacent openings 101, connecting the two base layers 10 and forming a partition between adjacent openings 101. This scheme of sharing the connecting fiber 20 not only improves the utilization efficiency of the connecting fiber 20, but also improves the stability of the three-dimensional structure of the absorbent fabric 1.

[0050] A plane located between two adjacent base layers 10 and parallel to the plane containing these two base layers 10 is designated as the preset reference plane A. The preset reference plane A can be a virtual reference plane used to measure the density of the connecting fibers 20.

[0051] Specifically, within a unit region A1 (a standard unit area of ​​one square inch) within a preset reference plane A, such as Figure 2 As shown, the connecting fibers 20 penetrating the unit area A1 intersect with the preset reference plane A to form multiple circular or approximately circular cross-sections. The sum of the perimeters of the outer contours of these cross-sections constitutes a technical parameter of the humidifying mesh fabric—the preset total perimeter of the connecting fibers 20 within the unit area. The preset total perimeter quantifies the sum of the outer perimeters of the connecting fibers 20 within a unit area. This preset total perimeter is directly related to the "evaporation area" of the absorbent fabric 1, that is, the preset total perimeter determines the moisture evaporation capacity of the absorbent fabric 1.

[0052] The evaporation area can be understood as the total effective surface area of ​​the absorbent fabric 1 available for water evaporation. In the three-dimensional structure of the absorbent fabric 1, the evaporation area is affected by both the water absorption capacity of the base layer 10 and the outer peripheral area of ​​the connecting fibers 20. When the connecting fibers 20 are soaked in water, a water film forms on their surface. This water film exchanges heat and mass with the flowing air, thus achieving water evaporation. The preset total perimeter P of the connecting fibers per unit area affects the size of the evaporation area of ​​the absorbent fabric 1, because the total perimeter of the connecting fibers 20 is directly proportional to the surface area of ​​the connecting fibers 20.

[0053] In order to improve the humidification performance of the absorbent fabric 1 and the energy efficiency ratio of the humidification device, the absorbent fabric provided in this application limits the above-mentioned preset total perimeter P within a suitable range in a unit area A1 of one square inch, that is, P satisfies: 21.7mm≤P≤935.97mm.

[0054] P≥21.7mm, which enables the absorbent fabric 1 within the unit area A1 to have basic moisture retention capacity, and helps to form a water film on the surface of the connecting fiber 20.

[0055] If P≤935.97mm, the adhesion of connecting fibers 20 or capillary water flooding that may occur due to excessively large preset total perimeter is reduced, and the long-term stability of the absorbent fabric 1 structure is supported.

[0056] Thus, the absorbent fabric 1 provided in this application achieves a balance between water retention capacity and structural stability by controlling the preset total perimeter P of the connecting fibers 20 within a unit area of ​​one square inch to the range of 21.7 mm to 935.97 mm. The preset total perimeter P meeting the above requirements provides sufficient peripheral area of ​​the connecting fibers to form a water film, thereby improving the water evaporation efficiency of the absorbent fabric 1. Simultaneously, the preset total perimeter P meeting the above requirements also suppresses the adhesion or structural collapse of the connecting fibers 20 caused by excessive capillary action, helping to maintain the three-dimensional porous structure and support of the absorbent fabric 1, thereby improving the humidification function and service life of the absorbent fabric 1.

[0057] In some embodiments, within a unit area A1 of one square inch, a preset total perimeter P is provided, satisfying: 43.3mm≤P≤156mm.

[0058] P≥43.3mm, which improves the water load per unit area of ​​the absorbent fabric 1, and the connecting fiber 20 can form a relatively uniform water film on the surface, enhancing the water retention capacity of the absorbent fabric 1.

[0059] If P≤156mm, the capillary action intensity of the absorbent fabric 1 is controlled, reducing the possibility of moisture being locked in the gaps between the connecting fibers 20, and improving the stability of the evaporation rate of the absorbent fabric 1.

[0060] Thus, the range of 43.3mm≤P≤156mm is suitable for most humidification needs, maintaining the humidification efficiency of the absorbent fabric 1 while ensuring the structural reliability of the absorbent fabric 1.

[0061] In some embodiments, within a unit area A1 of one square inch, a preset total perimeter P is provided, satisfying: 77.9mm≤P≤130mm.

[0062] P≥77.9mm provides sufficient evaporation area for the absorbent fabric 1, prolonging the residence time of air in the absorbent fabric 1, thereby improving the gas-liquid exchange efficiency.

[0063] When P ≤ 130 mm, the distribution density of the appropriate connecting fibers 20 in the absorbent fabric 1 is further reduced, balancing capillary force with gravity and airflow shear force. Thus, the range of 77.9 mm ≤ P ≤ 130 mm achieves a balance between humidification performance and energy efficiency by coordinating the water holding capacity and evaporation rate of the absorbent mesh 1. This balance reduces dripping caused by weak capillary force in the absorbent fabric, and also reduces the risk of "dry spots" formed due to excessively strong capillary force and locked-in moisture. Dry spots refer to localized dry areas on the surface of the absorbent fabric caused by insufficient moisture supply and uneven evaporation.

[0064] In some embodiments, the preset total perimeter P is directly proportional to the product of several parameters. These parameters include: the diameter of the connecting fiber 20 (i.e., the diameter of a single fiber), the number of connecting fibers 20 connected within the threading hole 1011 (i.e., the number of fibers actually passing through each threading hole 1011), the number of threading holes 1011 contained in each opening 101, and the total number of openings 101 within a unit area A1. By coordinating and controlling these structural parameters, the size of the evaporation area can be controlled.

[0065] Specifically, within a unit area A1 of the preset reference plane A, the diameter of the connecting fiber 20, as a basic dimensional parameter, determines the perimeter of a single fiber. Increasing the diameter linearly increases the moisture-carrying capacity per unit length of fiber surface. The number of fibers within the threading holes 1011 reflects the distribution density of the connecting fibers 20; increasing or decreasing the number of connecting fibers 20 adjusts the number of evaporation points per unit area. The number of threading holes 1011 within a single opening 101 controls the structural complexity of the absorbent fabric 1, and their size affects the diffusion path and efficiency of moisture in the planar direction. The number of openings 101 within unit area A1 (holes / inch) 2 The porosity of the absorbent fabric 1 is reflected in the overall porosity, which determines the distribution density of the airflow channels and the air residence time.

[0066] It is understandable that these parameters interact and, through a product relationship, jointly determine the total contact area between the connecting fiber 20 and the air per unit area. By establishing a direct proportional relationship between the preset total perimeter P and the product of the above parameters, the size of the evaporation area of ​​the absorbent fabric 1 can be adjusted and controlled.

[0067] Thus, the absorbent fabric 1 provided in this embodiment achieves a balance between humidification performance and structural stability by quantitatively controlling the preset total perimeter P. When it is necessary to improve humidification efficiency, the preset total perimeter can be appropriately increased to expand the evaporation area. By adjusting the combination of parameters such as the inner diameter of the filament per square inch, the number of fibers, the number of thread holes 1011, or the number of openings 101, the water evaporation rate of the absorbent fabric 1 can be increased. When it is necessary to enhance the structural stability of the absorbent fabric 1, the preset total perimeter can be reduced to adjust the capillary action intensity. By reducing fiber density or filament diameter, etc., the adhesion of connecting fibers 20 and capillary flooding can be reduced.

[0068] In some embodiments, the preset total circumference P satisfies: P = (π × D) × (M × N × Q) / K; where D is the diameter of the connecting fiber, M is the number of threading holes in the opening, N is the number of connecting fibers connected in the threading holes, Q is the number of openings in a unit area, and K is a coefficient used to correct the repeated count of connecting fibers shared by adjacent openings.

[0069] Wherein, (π×D) represents the perimeter of the outline of a single connecting fiber 20, characterizing the water-holding capacity of a single connecting fiber 20. (M×N×Q) represents the total number of connecting fibers 20 in a unit area before correction, where M is the number of threading holes 1011 in a single opening, N is the number of connecting fibers 20 connected in a single threading hole 1011, and Q is the number of openings 101 in a unit area.

[0070] K is the fiber sharing coefficient, used to correct for duplicate counting of shared fiber connections between adjacent openings. K is a positive integer greater than 1. For example, when a fiber connection is shared by two adjacent openings, K is usually 2. The reason for dividing (π×D)×(M×N×Q) by the fiber sharing coefficient K is that, since fiber connection 20 is shared between adjacent openings 101, the same fiber connection 20 will be counted repeatedly in the fiber count of multiple connected openings 101.

[0071] In some embodiments, K = 2. For example, when a connecting fiber 20 is shared by two adjacent openings 101, the connecting fiber 20 will be counted twice, so K = 2 is needed to correct this double counting.

[0072] In some embodiments, M satisfies: 12 ≤ M ≤ 30.

[0073] When M≥12, each opening 101 has a sufficient number of threading holes 1011, so that the connecting fiber 20 can form a support structure with sufficient support, so that moisture can be fully wetted and retained at the edge of the opening 101, providing conditions for efficient gas-liquid exchange.

[0074] When M≤30, the risk of weakening of the structural strength of the opening 101 due to an excessive number of thread holes 1011 is reduced, and the weaving of the base layer 10 is prevented from bearing too much weight and affecting the stability of the overall structure.

[0075] The setting of 12≤M≤30 allows a single opening 101 to retain and diffuse moisture through an appropriate number of connecting fibers 20 while maintaining reasonable structural strength, thus providing conditions for improving the evaporation efficiency per unit area. By controlling the M value within the above range, the capillary force of the absorbent fabric 1 is improved, while the problem of increased ventilation resistance caused by excessively dense connecting fibers 20 is reduced.

[0076] Specifically, M can be 12, 15, 18, 20, 23, 25, 30, etc.

[0077] In some embodiments, the number N of connecting fibers 20 connected within a single thread hole 1011 satisfies: 2≤N≤24.

[0078] If N≥2, then a single thread hole 1011 contains multiple connecting fibers 20, which helps to form a stable support for the base layer 10 by the connecting fibers 20, maintain the spacing between the two base layers 10, and keep the connecting fibers 20 in a stable structural form.

[0079] If N≤24, there is a risk that the number of connecting fibers 20 in a single threading hole 1011 may be too large, leading to saturation of the threading hole 1011 and excessive compression between the connecting fibers 20, which may affect the effectiveness of capillary action.

[0080] Specifically, N can be 2, 4, 6, 8, 10, 12, 16, 20, 24, etc.

[0081] In some embodiments, D satisfies: 7μm≤D≤30μm.

[0082] D≥7μm ensures that the connecting fiber 20 has sufficient mechanical strength to reliably connect and support the two base layers 10, maintaining the structural stability of the absorbent fabric 1.

[0083] If D30≤μm, it reduces the space between the two openings 101 of the two adjacent base layers 10 due to the excessively large diameter of the connecting fiber 20, which helps to reduce the overall ventilation resistance of the absorbent fabric 1.

[0084] With a filament diameter range of 7μm ≤ D ≤ 30μm, the connecting fiber 20 can provide structural support while minimizing obstruction of the airflow channel between the two openings 101, thus balancing the structural performance and ventilation requirements of the absorbent fabric 1. Furthermore, by controlling the filament diameter unit of the connecting fiber 20, the capillary force of a single connecting fiber 20 is also controlled, which helps to achieve a uniform distribution of moisture on the surface of the connecting fiber 20, ensuring that the surface characteristics of the connecting fiber 20 are coordinated with the water-holding capacity of the base layer 10.

[0085] Specifically, D can be 7μm, 20μm, 23μm, 25μm or 30μm.

[0086] Furthermore, the coordinated adjustment of the number of connecting fibers 20 and the connecting fiber filaments 20, such as 4 connecting fibers 20 per hole with a filament diameter of 23μm, can balance capillary force, gravity, and airflow shear force, improve the stability of the water-holding state of the connecting fibers 20, and reduce dripping and dry spot phenomena. Specifically, this can be verified by observing the temperature distribution difference displayed by infrared thermal imaging on the absorbent fabric 1.

[0087] In some embodiments, Q satisfies: 25 / inch² ≤ Q ≤ 36 / inch².

[0088] Q≥25 / inch2 ensures that the absorbent fabric 1 has sufficient mesh density, forming evenly distributed airflow channels and providing a sufficient gas-liquid exchange interface for moisture evaporation.

[0089] If Q≤36 / inch2, the risk of reduced structural strength of the base layer 10 due to excessive mesh density is reduced, and the concentration of connecting fibers 20 is prevented from affecting the overall stability of the fabric.

[0090] The setting of 25 particles / inch² ≤ Q ≤ 36 particles / inch² enables the absorbent fabric 1 to achieve efficient airflow and moisture exchange while maintaining appropriate structural strength. Furthermore, 25 / inch² ≤ Q ≤ 36 / inch² also shortens the air diffusion path within the absorbent fabric 1, extending the air residence time and improving air-liquid exchange efficiency.

[0091] The above-mentioned effects can be verified by performing CFD simulation on the eddy current distribution of the absorbent fabric 1.

[0092] It is understandable that by controlling the Q value within the above range, in conjunction with the number of thread holes 1011 M, the number of fibers N, and the filament diameter D, the preset total circumference P can be controlled, thereby taking into account the balance between the water-holding capacity, evaporation efficiency, and ventilation performance of the absorbent fabric 1.

[0093] In some embodiments, the value of Q, the number of openings 101 in a unit area A1, is inversely correlated with the value of N, the number of connecting fibers 20 connected in each thread hole 1011.

[0094] Specifically, when the value of Q approaches the upper limit of the range, the value of N can approach the lower limit of the range accordingly, and when the value of Q approaches the lower limit of the range, the value of N can approach the upper limit of the range accordingly.

[0095] This combination ensures that the absorbent fabric 1 has a sufficient total amount of connecting fibers 20 to maintain structural strength and water retention capacity, while also reducing the risk of airflow obstruction caused by both the opening 101 and the connecting fibers 20 being too dense.

[0096] In practice, when Q is 36 strands / inch², N can be 2-4 strands / hole; when Q is 25 strands / inch², N can be 8-12 strands / hole. This improves the structural stability of the absorbent fabric 1 while maintaining its good breathability, achieving a relatively balanced state between moisture evaporation and air circulation.

[0097] In some embodiments, when Q ≥ 30 / inch², N ≤ 4.

[0098] When the Q value is large, the distribution of openings 101 on the base layer 10 is relatively dense. At this time, controlling the N value at a low level can both enable the connecting fibers 20 to form a sufficient support network and reduce the obstruction of airflow due to the excessive density of the connecting fibers 20. It is particularly suitable for scenarios requiring high humidification efficiency, and can maintain a large evaporation area while ensuring smooth airflow, thereby improving the moisture evaporation rate of the absorbent fabric 1.

[0099] To illustrate the specific impact of the above parameter relationships on the preset total perimeter P, Table 1 is provided in this application embodiment to show the theoretical values ​​calculated using the formula P = (π × D) × (M × N × Q) / K under different parameter combinations. Table 1 reflects the relationship between the above parameters and the preset total perimeter P, providing a specific basis for optimizing the humidification performance and structural stability of the absorbent fabric 1.

[0103] Table 1 shows the preset total perimeter P values ​​under different parameter combinations. The data shows that the P value increases accordingly as the values ​​of parameters M, N, and Q increase. For example, when M increases from 12 to 30, Q increases from 25 to 36, and N remains at 2 (numbers 1 to 3), the P value increases from 21.666 mm / inch. 2 Increased to 77.9976 mm / inch 2 When N increases from 2 to 4, while M and Q remain constant (from number 1 to number 2), the P value increases from 21.666 mm / inch. 2 Increased to 43.332 mm / inch 2 .

[0104] Numbers 4 and 5 show the optimal intermediate parameter combinations, where when M=20 and Q=30, the N value increases from 4 to 6, and the P value increases from 86.664 mm / inch. 2 Increased to 129.996 mm / inch 2 Tables 6 through 8 further illustrate the trend of N increasing from 4 to 24 and then to 48 when M=30 and Q=36 are fixed: the corresponding P value increases from 155.9952 mm / inch. 2 Significantly increased to 935.971 mm / inch 2 And ultimately reached 1871.94 mm / inch. 2 .

[0105] It should be noted that the P values ​​calculated for the parameter combinations in number 8 (especially N=24 and N=48) are higher than those for other groups. In number 8, excessively high connecting fiber density and total perimeter P may lead to structural instability or even collapse of the absorbent fabric. The data in number 8 is mainly used to illustrate the theoretical calculation range of the formula. In practical applications, the optimal parameter combinations within the range of numbers 1 to 7 should be given priority to balance the humidification performance and structural stability of the absorbent fabric 1.

[0106] As can be seen, by adjusting the combinations of values ​​for M, N, and Q, the value of P can be controlled within the desired range. For example, using parameter combination number 4 (M=20, N=4, Q=30) yields 86.664 mm / inch. 2 The P value helps to balance the humidification performance and structural stability of the absorbent fabric 1.

[0107] Based on the above description, the absorbent fabric 1 provided in this application embodiment improves the moisture distribution of the absorbent fabric 1 by controlling the preset total circumference P of the connecting fibers 20, thereby forming a water film on the surface of the connecting fibers 20 and increasing the moisture load per unit area of ​​the absorbent fabric 1. Specifically, this can be verified by measuring the moisture content of the absorbent fabric 1 using a weighing method.

[0108] like Figure 3 As shown, an embodiment of the second aspect of this application also provides a water storage component 2, which includes an absorbent fabric 1 and a water-wicking fabric 210. 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.

[0109] At least two base layers 10 of the absorbent fabric 1 are arranged along the thickness direction of the absorbent fabric 1, and the absorbent fabric 1 is formed into a tubular water storage mesh 200 along the length direction of the at least two base layers 10. The water-guiding fabric 210 covers the axial end of the water storage mesh 200.

[0110] When the airflow passes through the cylindrical water storage mesh 200 along the axial direction, it comes into full contact with the water storage mesh 200, thereby causing gas-liquid exchange and allowing the water inside the water storage mesh 200 to evaporate.

[0111] like Figure 3 As shown, the water-guiding fabric 210 covers at least a portion of the outer end of the water-storage mesh 200 along the axial direction of the water-storage mesh 200, such that the water-guiding fabric 210 covers at least a portion of the end face of the water-storage mesh 200.

[0112] The water-guiding fabric 210 covers the end face of the water-storing mesh 200, enabling it to fix at least a portion of the edge of the water-storing mesh 200, thus achieving an edge-sealing effect. The water-guiding fabric 210 provides structural support to the end of the water-storing mesh 200, improving its shape stability, reducing deformation or collapse, and ensuring sufficient contact area between the water-storing mesh 200 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 200. Since the structural shape of the water-storing mesh 200 is prone to gaps at the edges, the water-guiding fabric 210 can wrap around these edges, making the edges of the water-storing component 2 smoother, increasing the contact area between the water-storing component 2 and water, and improving its water-guiding effect.

[0113] In addition, the water-guiding fabric 210 has good air permeability and permeability. The liquid first contacts the water-guiding fabric 210 and then enters the water-storage mesh 200. When the liquid flows through the water-guiding fabric 210, it undergoes permeation and diffusion, which improves the uniformity of liquid distribution. This allows the water-guiding fabric 210 to play a role in uniformly distributing water to the water-storage mesh 200 below, thus optimizing the water absorption effect of the water-storage mesh 200.

[0114] The water-wicking fabric 210 is a fabric. Exemplarily, the fabric can be a single-layer porous substrate formed from synthetic fibers (such as polyester, nylon) or natural fibers (cotton yarn) through a weaving process. The surface of the water-wicking fabric 210 has regularly distributed geometric openings (such as regular hexagons or squares, with a diagonal of 2-12 mm), and a mesh density of 5-30 meshes / cm². 2 .

[0115] The water-wicking fabric 210 can be single-layered or double-layered. When single-layered, the water-wicking fabric 210 is made of PET polyester with a thickness of less than 2mm, thus possessing thin, breathable, and easily permeable properties. When double-layered, the upper layer of the water-wicking fabric 210 has larger openings, while the lower layer has smaller openings (the lower layer openings are approximately one-tenth the size of the upper layer openings), and the two layers are connected by fiber threads.

[0116] In some embodiments, the height of the water storage mesh 200 is H1, and the height of the water-guiding fabric 210 along the axial direction of the water storage mesh 200 is H2, wherein H2≤0.2H1.

[0117] With H2 ≤ 0.2H1, the water-guiding fabric 210 provides sufficient edge sealing and water-guiding functions without excessively covering the evaporation area of ​​the water storage mesh 200. By controlling the height of the water-guiding fabric 210 to not exceed 20% of the total height of the water storage mesh 200, direct gas-liquid exchange capacity is achieved in most areas of the water storage mesh 200, while the water-guiding fabric 210 at the edges achieves the dual functions of uniform moisture distribution and structural reinforcement.

[0118] In some embodiments, the height of the water storage mesh 200 is H1, and the height of the water guiding fabric 210 along the axial direction of the water storage mesh 200 is H2, where 1cm≤H2≤3cm.

[0119] H2≥1cm, so that the water-guiding fabric 210 has sufficient coverage area to achieve the sealing and water-guiding functions, in order to wrap the edge gap of the water storage mesh 200.

[0120] If H2≤3cm, the risk of the water-conducting fabric 210 being too high and affecting the main evaporation performance of the water storage net 200 is reduced, while the amount of water-conducting fabric 210 used and the production cost are controlled.

[0121] like Figure 4 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.

[0122] The humidifier 3 also includes a fan assembly 310, which is used to agitate the airflow and make the airflow flow through the water storage unit 2, so that the water on the water storage unit 2 evaporates and flows with the airflow into the indoor environment, thereby humidifying the air.

[0123] In some embodiments, the fan speed of the fan assembly 310 is positively correlated with the preset total circumference P of the absorbent fabric 1 of the water storage component 2.

[0124] When the P value is large, the humidification device 3 can correspondingly increase the fan speed of the fan assembly 310 to match the airflow velocity with the increased gas-liquid exchange area. When the P value is small, the humidification device 3 can correspondingly decrease the fan speed to adapt the airflow velocity to the reduced evaporation area. This speed adjustment method keeps the airflow rate and evaporation area in harmony, which helps to improve the gas-liquid exchange efficiency.

[0125] Furthermore, proper speed matching of the fan assembly 310 can promote uniform evaporation of water in the water storage component 2, reducing localized drying or water accumulation caused by uneven evaporation rates. For water storage components 2 or absorbent fabrics 1 with different structures, the fan speed can be adjusted to suit their water retention characteristics and evaporation requirements.

[0126] Thus, by adjusting the relationship between the fan speed and the preset total circumference P value, the airflow velocity is adapted to the evaporation capacity of the absorbent fabric 1. When the P value is large, a higher fan speed is used to fully utilize the increased evaporation area; when the P value is small, a lower fan speed is used to reduce energy waste. This helps maintain appropriate airflow impact force, reducing the mechanical load on the high-density fiber structure, while preventing the adhesion of connecting fibers 20 caused by excessively long water retention time due to excessively low airflow velocity. The relationship between the fan speed and the P value provides a suitable working environment for water storage components 2 or absorbent fabric 1 with different structures, supporting the long-term stable operation of the humidification device 3.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
