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 absorbent fabric as the humidifying substrate. This absorbent fabric includes a first substrate with multiple openings and a second substrate with multiple openings, spaced apart and connected to each other by connecting fibers. When the humidifier is operating, a water supply device keeps the absorbent fabric moist, and a fan assembly directs airflow through the moist fabric, causing the moisture to evaporate and enter the indoor environment, thus achieving humidification.

[0003] However, the connecting fibers of the absorbent fabric are prone to deformation during manufacturing or use and can enter the tiny airflow channels formed by the openings in the first and second substrates of the humidifying substrate. This can lead to blockage of the airflow channels or a reduction in the airflow area, resulting in a decrease in the humidification efficiency of the absorbent fabric and an increase in wind resistance. Consequently, the energy consumption of the humidification device increases and the humidification effect decreases. Utility Model Content

[0004] This application discloses an absorbent fabric, a water storage component, and a humidification device, which can effectively control wind resistance, inhibit water film formation, and improve ventilation and humidification uniformity, thereby improving the overall performance and energy efficiency of the humidification device.

[0006] In one possible implementation, the extending direction of the connecting fiber at the connection point of the first substrate forms a first angle θ1 with the plane of the first substrate; the extending direction of the connecting fiber at the connection point of the second substrate forms a second angle with the plane of the second substrate.

[0007] In one possible implementation, the first included angle may be equal to or unequal to the second included angle.

[0008] In one possible implementation, θ1≤60° and / or θ2≤60°.

[0009] In one possible implementation, the connecting fiber is bent between the first opening and the second opening;

[0010] The connecting fiber has a first tangent at the connection point of the first substrate, and the first tangent forms a first angle θ1 with the plane of the first substrate; the connecting fiber has a second tangent at the connection point of the second substrate, and the second tangent forms a second angle θ2 with the plane of the second substrate.

[0011] In one possible implementation, the number of connecting fibers located outside the airflow channel is K, and the number of connecting fibers located inside the airflow channel is J, wherein K / J ≥ 80%.

[0012] In one possible implementation, the connecting fibers are arranged at an angle relative to the first direction, which is the arrangement direction of the first substrate and the second substrate.

[0013] In one possible implementation, on a projection plane perpendicular to the first direction, at least a portion of the projection of the connecting fibers lies within the outline of the first opening and / or the outline of the second opening, where the first direction is the arrangement direction of the first substrate and the second substrate.

[0014] In one possible implementation, each first opening is provided with a plurality of first threading holes, and each second opening is provided with a plurality of second threading holes. The connecting fiber is connected between the first threading holes and the second threading holes, and the number of connecting fibers connected in the first threading hole or the second threading hole is N; wherein, N satisfies: 2≤N≤48.

[0015] In one possible implementation, the distance between the first substrate and the second substrate is H, where H satisfies: 1.5mm < H < 13.5mm.

[0016] In one possible implementation, the diameter of the connecting fiber is D, where 7μm≤D≤30μm.

[0017] In one possible implementation, when the absorbent fabric is wet under a pressure of 10 kPa, the stiffness retention rate of the absorbent fabric is ≥90%.

[0018] In one possible implementation, under a pressure of 10 kPa, the thickness reduction rate M of the absorbent fabric in a dry state is ≤20%.

[0019] The second aspect of this application provides a water storage device, which includes: the absorbent fabric described in the first aspect of this application, wherein a first substrate and a second substrate of the absorbent fabric are disposed along the thickness direction of the absorbent fabric, and the first substrate and the second substrate are enclosed in a cylindrical water storage mesh along the length direction; and a water guiding mesh covering the two ends of the water storage mesh along the axial direction.

[0023] The absorbent fabric provided in this application embodiment, by placing the connecting fibers at a non-perpendicular angle between the first substrate and the second substrate, with most of the connecting fibers located outside a single airflow channel, can guide the connecting fibers to compress and deform along a predetermined trajectory in a first direction when under pressure. This reduces the risk of the connecting fibers collapsing and excessively intruding into the airflow channel, and improves the structural stability and resistance to pressure and deformation of the absorbent fabric. At the same time, it reduces the wind resistance fluctuation and ventilation energy loss under wet use of the absorbent fabric, and improves the unobstructed airflow and humidification efficiency stability of the humidification device during long-term operation.

[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.

For example, the term "above" may also be used in certain circumstances to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

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. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (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, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0040] Humidifiers typically use absorbent fabric as their core humidification component. The absorbent fabric mainly consists of a first substrate, a second substrate, and connecting fibers. The first substrate and the second substrate are spaced apart along their thickness direction and are connected to each other by multiple connecting fibers.

[0041] Specifically, the first substrate and the second substrate each have a plurality of first openings and second openings, forming a three-dimensional perforated structure that penetrates the absorbent fabric along the thickness direction. This three-dimensional perforated structure is used for air circulation. Connecting fibers are arranged in a curved form between the first substrate and the second substrate, and some sections of the connecting fibers are bent toward the interior of the three-dimensional perforated structure, that is, extending into the area inside the three-dimensional perforated structure. In this way, the connecting fibers will, to some extent, encroach on the original ventilation space of the three-dimensional perforated structure, resulting in an increase in the air resistance of the absorbent fabric.

[0042] Furthermore, when the connecting fibers bend into the three-dimensional porous structure, the degree of bending of the connecting fibers is easily further increased when the absorbent fabric is subjected to pressure, humidity, or mechanical vibration during use. This makes it easier for the connecting fibers to tilt, bend, and collapse into the three-dimensional porous structure, thereby reducing the effective ventilation area of ​​the three-dimensional porous structure. This leads to a further increase in the wind resistance of the absorbent fabric and makes it easier to form a continuous water film in the area where the connecting fibers gather, hindering the normal evaporation of moisture and causing a decrease in the humidification efficiency and an increase in energy consumption of the humidification equipment.

[0043] To improve the performance of absorbent fabrics, some technologies have attempted to increase the size of the first and second openings to expand the ventilation cross-section and slow down the formation of water film within the three-dimensional porous structure. However, this approach leads to new problems: with larger openings, the proportion of connecting fibers used for support decreases, resulting in a reduction in the overall structural rigidity of the absorbent fabric. Under wet or pressure conditions, it becomes more prone to collapse, creep, or permanent deformation. Furthermore, enlarged openings, under stress, can further cause misalignment between the first and second openings, leading to further obstruction or distortion of the three-dimensional porous structure. Consequently, the actual ventilation volume of the absorbent fabric decreases instead of increasing, failing to achieve the goal of improving humidification performance.

[0044] Furthermore, due to the aforementioned problems, the wind resistance of the absorbent fabric in a wet state will continuously increase during actual use. The humidification device must increase the fan power to overcome this resistance, leading to a decrease in the overall energy efficiency ratio and an increase in operating noise. It also accelerates the structural fatigue of the absorbent fabric, shortening its service life. Therefore, this application proposes an absorbent fabric that can effectively control wind resistance, inhibit water film formation, and improve ventilation and humidification uniformity, thereby improving the overall performance and energy efficiency of the humidification device.

[0045] like Figures 1 to 4 As shown, this application embodiment 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 assembly 310 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.

[0046] like Figure 1 As shown, the absorbent fabric 1 includes a first substrate 10 and a second substrate 20, which are spaced apart. The direction in which the first substrate 10 and the second substrate 20 are spaced apart is a first direction, or it can be understood as the first substrate 10 and the second substrate 20 being spaced apart along a first direction. The first direction can be... Figure 1 The Y direction is shown. It can be understood that the absorbent fabric 1 may include a plurality of first substrates 10 and a plurality of second substrates 20 arranged along the first direction.

[0047] When the absorbent fabric 1 is laid flat, that is, when the first substrate 10 and the second substrate 20 are unfolded, the first direction can be perpendicular or approximately perpendicular to the first substrate 10 and the second substrate 20.

[0048] like Figure 1 and Figure 2As shown, the first substrate 10 can be a fabric woven from yarn. Multiple first openings 101 can be provided on the first substrate 10. The first openings 101 are used for airflow. The interior of the first opening 101 is hollow, and the edge contour of the first opening 101 is a structure woven from yarn. Adjacent first openings 101 can share a portion of their edge contour.

[0049] like Figure 1 and Figure 2 As shown, the second substrate 20 can be a fabric woven from yarn. Multiple second openings 201 can be provided on the second substrate 20. The second openings 201 are used for airflow. The interior of the second opening 201 is hollow, and the edge contour of the second opening 201 is a structure woven from yarn. Adjacent second openings 201 can share a portion of their edge contour.

[0050] like Figure 2 As shown, viewed along the first direction, a through airflow channel 30 is formed between the first opening 101 and the second opening 201, that is, a three-dimensional perforated structure for ventilation is formed between the first opening 101 and the second opening 201. When the humidifier is running, air flows in from the first opening 101, passes through the airflow channel 30, and then flows out from the second opening 201. During this process, the air comes into contact with water molecules adhering to the surfaces of the first opening 101, the second opening 201, and the connecting fiber 40, and carries the evaporated moisture out, thereby achieving the humidification function. If the airflow channel 30 is blocked, it will lead to increased airflow resistance, increased energy consumption and operating noise of the humidifier, and a decrease in ventilation volume, resulting in a significant reduction in humidification efficiency. Therefore, keeping the airflow channel 30 unobstructed is crucial for achieving efficient and stable operation of the humidifier 3.

[0051] like Figure 2 As shown, along the first direction, the first opening 101 and the second opening 201 can be correspondingly arranged. That is, the projections of the first opening 101 and the second opening 201 onto the first direction can overlap or approximately overlap. It can be understood that by correspondingly arranging the first opening 101 and the second opening 201, the ventilation area of ​​the perforation structure can be maximized without changing the shape and size of the first opening 101 and the second opening 201, thereby reducing the air resistance of the absorbent fabric 1 when it is wet.

[0052] like Figure 2 As shown, connecting fibers 40 are connected between the outlines of the first opening 101 and the second opening 201 (e.g., passing through the first threading hole 1011 and the second threading hole 2011). Each pair of first openings 101 and second openings 201 are connected by connecting fibers 40, thereby achieving the connection between the first substrate 10 and the second substrate 20. Figure 2As shown, the connecting fiber 40 can also be composed of multiple independent fibers connected between the first substrate 10 and the second substrate 20 respectively. For example... Figure 3 As shown, in the actual process, the connecting fiber 40 can be woven between the first substrate 10 and the second substrate 20 in a back-and-forth manner using a continuous fiber thread.

[0053] like Figure 4 and Figure 5 As shown, the connecting fiber 40 is connected between the first opening 101 and the second opening 201 at an angle not perpendicular to the first substrate 10 and / or the second substrate 20. Figure 3 and Figure 4 This is a view of the absorbent fabric 1 as observed from a side view perpendicular to the first direction.

[0054] Specifically, when the connecting fiber 40 connects the first opening 101 and the second opening 201, its extension direction does not form a right angle with the plane where the first substrate 10 or the second substrate 20 is located. "Non-perpendicular" configuration includes the connecting fiber 40 extending in an inclined straight line, as well as extending in a non-linear form such as a bend or arc. Regardless of the form, the extension direction of the connecting fiber 40 at the connection point is not perpendicular to the plane where the first substrate 10 or the second substrate 20 is located.

[0055] At least some of the connecting fibers 40 are located outside the airflow channel 30. This can be understood as most or all of the connecting fibers 40 projecting along the first direction outside the projection area of ​​the first opening 101 / second opening 201 along the first direction. That is, these connecting fibers 40 do not extend into the airflow channel 30 between the first opening 101 and the second opening 201. When viewed from the first direction, or when observing the absorbent fabric 1 from above the first or second surface layer, this portion of the connecting fibers 40 is not observed from the first opening 101 or the second opening 201. Figure 4 and Figure 5 As shown, the state in which the connecting fiber 40 is connected "non-perpendicularly" between the first substrate 10 and the second substrate 20 can be observed from a direction perpendicular to the first direction (i.e., the side of the absorbent fabric 1).

[0056] It should be noted that in actual manufacturing processes, due to the complexity of manufacturing precision and the weaving of the connecting fibers 40, it may be difficult to ensure that all connecting fibers 40 avoid the airflow channel 30. Therefore, the statement in this embodiment that "at least some connecting fibers 40 are located outside the airflow channel" indicates that most of the connecting fibers 40 in the absorbent fabric 1 do not extend into the airflow channel 30, but a small portion of the connecting fibers 40 may extend into the airflow channel 30 due to process limitations. If the process conditions permit, all connecting fibers 40 are located outside the airflow channel.

[0057] In this way, in the initial state of the absorbent fabric 1, most of the connecting fibers 40 do not extend into the three-dimensional hole formed by the connection between the first opening 101 and the second opening 201, ensuring that the airflow channel 30 remains unobstructed from the initial stage and is not significantly obstructed by the connecting fibers 40. This reduces the risk of increased wind resistance, eddy current generation, or uneven local wind speed that may be caused by improper initial positioning of the connecting fibers 40, providing a structural basis for the absorbent fabric 1 to achieve continuous low wind resistance operation.

[0058] It should be noted that by setting the connecting fiber 40 at a non-perpendicular angle, the risk of the connecting fiber 40 collapsing, shaking, or deforming and intruding into the channel when it is set upright along the first direction under pressure or impact can be effectively reduced. Specifically, when the absorbent fabric 1 is under pressure or in a wet state, the first substrate 10 and the second substrate 20 may approach each other along the first direction and apply pressure to the connecting fiber 40. If the connecting fiber 40 is set perpendicular to the first substrate 10 and the second substrate 20, it is prone to buckling in any direction due to instability during the pressure process, and there is a high probability that it will collapse or intrude into the interior of the airflow channel 30, resulting in a reduction in the ventilation area of ​​the airflow channel 30 and easy formation of a water film, thereby increasing the air resistance of the absorbent fabric 1. In contrast, in this application, the connecting fiber 40 is disposed in a non-perpendicular manner between the first substrate 10 and the second substrate 20. This configuration can provide clear deformation guidance when under pressure, guiding the connecting fiber 40 to undergo elastic deformation in areas outside the airflow channel 30. For example, it can be further compressed as a whole in the first direction along the original bending or tilting direction, thereby effectively reducing the risk of the connecting fiber 40 buckling or intruding into the airflow channel 30, so as to maintain the unobstructed flow of the airflow channel 30.

[0059] Therefore, the two structural features of the connecting fibers 40 being arranged non-perpendicularly between the first substrate 10 and the second substrate 20, and mostly remaining outside the airflow channel 30, work together to reduce the risk of the connecting fibers 40 blocking the airflow channel 30. On the one hand, most of the connecting fibers 40 are initially located outside the airflow channel 30, minimizing the intrusion of connecting fibers 40 into the interior of the airflow channel 30, thus preventing excessive connecting fibers 40 from occupying the internal space of the airflow channel 30; on the other hand, the non-perpendicular shape of the connecting fibers 40 causes them to be compressed in the first direction under pressure, reducing the possibility of them collapsing into the airflow channel 30. Through the above structural design, the absorbent fabric 1 can still keep the airflow channel 30 unobstructed when subjected to pressure or moisture-absorbing deformation, thereby maintaining stable ventilation and humidification performance.

[0060] Thus, the absorbent fabric 1 provided in this application embodiment, by setting the connecting fibers 40 at a non-perpendicular angle between the first substrate 10 and the second substrate 20, with at least a portion of the connecting fibers 40 located outside the single airflow channel 30, can effectively guide the connecting fibers 40 to compress and deform along a predetermined trajectory in the first direction when under pressure, reducing the risk of the connecting fibers 40 falling over and intruding into the airflow channel 30, and improving the structural stability and pressure and deformation resistance of the absorbent fabric 1. At the same time, it reduces wind resistance fluctuations and ventilation energy loss under wet conditions, and improves the unobstructedness of the airflow channel 30 and the stability of humidification efficiency of the humidification device 3 during long-term operation.

[0061] like Figure 4 and Figure 5 As shown, in some embodiments, the extending direction of the connecting fiber 40 at the connection point of the first substrate 10 forms a first angle θ1 with the plane where the first substrate 10 is located.

[0062] The first included angle θ1 causes the connecting fiber 40 to extend from the first substrate 10 in a non-perpendicular manner. This angle setting gives the connecting fiber 40 a clear tilt or bending guide at its starting end, providing a structural basis for constructing the connecting fiber 40 that does not intrude into the airflow channel 30.

[0063] The first included angle θ1 can be measured by the tangent direction of the connecting fiber 40 at the connection point of the first substrate 10, or by directly measuring its extension direction when the connecting fiber 40 is a straight segment at that point.

[0064] like Figure 4 and Figure 5 As shown, in some embodiments, the extending direction of the connecting fiber 40 at the connection point with the second substrate 20 forms a second angle with the plane where the second substrate 20 is located.

[0065] The second included angle θ2 determines the connection posture of the connecting fiber 40 to the second substrate 20 at its end. By controlling the included angles at both ends of the connecting fiber 40, the connecting fiber 40 can present various spatial forms, such as: maintaining an overall inclined straight line form, presenting a continuously changing smooth curved form, forming a segmented smooth turning form with specific turning points, etc.

[0066] In some embodiments, the first included angle and the second included angle are equal. The equality of the first included angle and the second included angle results in the connecting fiber 40 being symmetrically positioned between the first substrate 10 and the second substrate 20. This symmetrical shape allows the stress on the connecting fiber 40 to be relatively evenly distributed when the absorbent fabric 1 is subjected to pressure, reducing the likelihood of localized stress concentration. Simultaneously, the buckling and compression behavior of the connecting fiber 40 under pressure is somewhat predictable, enabling it to deform relatively along the first direction, further reducing the probability of the connecting fiber 40 buckling into the airflow channel 30 and maintaining the unobstructed flow of the airflow channel 30.

[0067] In some embodiments, the first included angle and the second included angle are not equal. In this way, when the absorbent fabric 1 is subjected to pressure, it can produce multi-segment deformation through the asymmetrical shape of the connecting fibers 40, so that the stress is gradually released in stages and regions to reduce stress concentration.

[0068] In some embodiments, θ1 ≤ 60°, allowing the connecting fiber 40 to extend from the first substrate 10 at a relatively gentle angle. This reduces the risk of the connecting fiber 40 collapsing due to its steeper extension from the first substrate 10, and also reduces the risk of insufficient height of the connecting fiber 40 along the first direction due to an excessively large first angle. By controlling the first angle θ1 within 60°, the connecting fiber 40 can provide better deformation guidance and compressive stability for the absorbent fabric 1 while ensuring support.

[0069] In some embodiments, θ2 ≤ 60°. By limiting the angle of the second included angle θ2, the connecting fiber 40 also maintains an inclined guide at its end, which, together with the angle of the first included angle θ1, constrains the overall shape of the connecting fiber 40, so that the connecting fiber 40 is distributed in a stable, non-vertical posture on the outside of the airflow channel 30, effectively preventing the end of the connecting fiber 40 from swinging or collapsing into the airflow channel 30, thereby taking into account both the structural integrity and ventilation stability of the airflow channel 30.

[0070] like Figure 4 As shown, in some embodiments, the connecting fiber 40 is bent between the first opening 101 and the second opening 201.

[0071] The connecting fiber 40 has a first tangent at the connection point with the first substrate 10, and the first tangent forms a first angle θ1 with the plane where the first substrate 10 is located; the connecting fiber 40 has a second tangent at the connection point with the second substrate 20, and the second tangent forms a second angle θ2 with the plane where the second substrate 20 is located.

[0072] By configuring the bending shape of the connecting fiber 40, when the absorbent fabric 1 is compressed, the bent connecting fiber 40 can expand or tighten on the outside of the connecting channel through its arc-shaped elastic deformation, thereby reducing the possibility of collapse or bending into the connecting channel. Simultaneously, by controlling the angles of the first included angle θ1 and the second included angle θ2 respectively, exemplarily θ1≤60° and θ2≤60°, the connecting fiber 40 presents a continuous arc bending to one side. This structure, while ensuring the structural reliability of the connecting fiber 40, provides it with greater deformation space and a better stress distribution, improving the compressive stability and deformation predictability of the absorbent fabric 1.

[0073] like Figure 5As shown, in some embodiments, the connecting fiber 40 is arranged at an angle relative to the first direction, which is the arrangement direction of the first substrate 10 and the second substrate 20.

[0074] By setting the connecting fiber 40 to extend at an angle, forming an inclined angle with the first direction, a support structure is constructed between the first substrate 10 and the second substrate 20. This inclined arrangement prevents the connecting fiber 40 from experiencing axial instability issues that are common when it is upright. When the absorbent fabric 1 is compressed along the first direction, the inclined connecting fiber 40 undergoes compression deformation along its inherent inclined direction. This directional deformation effectively guides the connecting fiber 40 to contract or bend outwards towards the airflow channel 30, reducing the likelihood of it randomly collapsing inwards towards the airflow channel 30.

[0075] In some embodiments, the number of connecting fibers 40 located outside the airflow channel 30 is K, and the number of connecting fibers 40 located inside the airflow channel 30 is J, wherein the ratio of K to J satisfies K / J ≥ 80%. This ratio indicates that most of the connecting fibers 40 do not extend into the airflow channel 30, thereby ensuring the overall unobstructed flow of the airflow channel 30 and the stability of the absorbent fabric 1's absorbency. Simultaneously, it also takes into account structural deviations of the connecting fibers 40 in actual manufacturing processes, achieving a reasonable balance between design and production as much as possible.

[0076] Specifically, K / J can be 80%, 90%, 92%, 95%, 97%, 99%, or 100%.

[0077] In some embodiments, on a projection plane perpendicular to the first direction, the projection of the connecting fiber 40 lies within the outline of the first opening 101 and / or the outline of the second opening 201, where the first direction is the arrangement direction of the first substrate 10 and the second substrate 20. That is, from... Figure 2 From the perspective of observation, the connecting fiber 40 is obscured by the threads of the first substrate 10 and the second substrate. At least a portion of the projection of the connecting fiber 40 into the first direction lies within the outline of the first opening 101 and the second opening 201.

[0078] The first opening 101 and the second opening 201 are hollow, ring-like structures woven from yarn, meaning their outlines are woven from yarn. Two adjacent first openings 101 can share at least a portion of their outlines, and adjacent second openings 201 can also share at least a portion of their outlines. The projection of the connecting fiber 40 into the first direction lies within the outlines of the first opening 101 and the second opening 201, ensuring that at least a portion of the connecting fiber 40 does not enter the interior of either of the two adjacent hole structures, and that at least a portion of the connecting fiber 40 does not obstruct each set of first openings 101 and second openings 201. This keeps the air resistance of the absorbent fabric 1 within a controllable range when wet.

[0079] In this way, the connecting fibers 40 avoid the airflow channels 30 formed by the first opening 101 and the second opening 201 in the initial state. From the projection perspective, most of the connecting fibers 40 do not block the airflow channels 30, thus minimizing the flow resistance and energy loss of the absorbent fabric 1.

[0080] like Figure 1 and Figure 2 As shown, in some embodiments, each first opening 101 is provided with a plurality of first threading holes 1011, and each second opening 201 is provided with a plurality of second threading holes 2011. Connecting fibers 40 are connected between the first threading holes 1011 and the second threading holes 2011. The number of connecting fibers 40 connected in the first threading hole 1011 or the second threading hole is N.

[0081] The first substrate 10 is woven from yarn, and the first opening 101 is formed by a plurality of interlocking loops, with a plurality of first thread holes 1011 formed between adjacent loops. The second substrate 20 is also woven from yarn, and the second opening 201 is formed by a plurality of interlocking loops, with a plurality of second thread holes 2011 formed between adjacent loops.

[0082] The connecting fiber 40 exits from the first threading hole 1011 of the first substrate 10 and extends into the second threading hole 2011 of the oppositely disposed second substrate 20, thereby connecting the first substrate 10 and the second substrate 20. The number of connecting fibers 40 connected in each first threading hole 1011 or second threading hole 2011 is N, where N satisfies: 2≤N≤48.

[0083] By inserting multiple connecting fibers 40 between the first substrate 10 and the second substrate 20, a densely distributed and regularly arranged fiber network can be constructed between the two substrate layers. These connecting fibers 40 have a certain degree of rigidity, which can firmly maintain the distance between the two substrate layers, and some tiny cavity structures, i.e., microcavity structures, are formed between two adjacent connecting fibers 40.

[0084] These microcavity structures can effectively adsorb and retain moisture, functioning as independent water storage units. Simultaneously, the specific bending angle of the connecting fibers 40 disrupts the straight flow of air, causing a certain deflection of the airflow within the microcavities. This disturbance increases the contact opportunities and time between air and water molecules, thereby contributing to improved water evaporation efficiency.

[0085] In some embodiments, the number N of the connecting fibers 40 connected in the first threading hole 1011 or the second threading hole 2011 satisfies: 2≤N≤48.

[0086] If N≥2, then the presence of multiple connecting fibers 40 within the first threading hole 1011 or the second threading hole 2011 helps to form a stable support for the first substrate 10 and the second substrate 20 by the connecting fibers 40, maintains the spacing between the first substrate 10 and the second substrate 20, and keeps the connecting fibers 40 in a stable structural form.

[0087] If N≤48, the risk of excessive number of connecting fibers 40 in the first threading hole 1011 or the second threading hole 2011, resulting in saturation of the volume of the first threading hole 1011 or the second threading hole 2011 and excessive compression between the connecting fibers 40, will be reduced, thus affecting the effectiveness of capillary action.

[0088] In some embodiments, the distance between the first substrate 10 and the second substrate 20 is H, where H satisfies: 1.5mm < H < 13.5mm.

[0089] With H > 1.5 mm, there is sufficient space between the first substrate 10 and the second substrate 20 to accommodate the connecting fiber 40 and form a stable three-dimensional structure. The distance H provides sufficient water storage volume, improves the unobstructed flow of the airflow channel 30, and reduces the risk of increased flow resistance caused by the small distance between the first substrate 10 and the second substrate 20.

[0090] If H < 13.5 mm, the overall thickness of the absorbent fabric 1 can be controlled within a reasonable range, reducing the risk of excessively long connecting fibers 40 due to excessive interlayer distance, thereby reducing the structural stability of the absorbent fabric 1 and increasing the risk of significant buckling of the connecting fibers 40 under pressure. It also facilitates the miniaturization and integration of the humidification device 3.

[0091] In some embodiments, the diameter of the connecting fiber 40 is D, where D satisfies: 7μm≤D≤30μm.

[0092] D≥7μm, so that the connecting fiber 40 has sufficient mechanical strength to connect and support between the first substrate 10 and the second substrate 20, and maintain the structural stability of the absorbent fabric.

[0093] If D≤30μm, the connection fiber 40 will be reduced from being squeezed into the airflow channel 30 due to its large diameter, which helps to reduce the overall ventilation resistance of the absorbent fabric.

[0094] The selection of a filament diameter range of 7μm≤D≤30μm allows the connecting fiber 40 to bear the structural support function while minimizing the degree of obstruction to the airflow channel 30, thereby taking into account both the mechanical properties and ventilation requirements of the absorbent fabric.

[0095] Specifically, the diameter D of the connecting fiber 40 can be 20μm, 23μm, 25μm, etc.

[0096] In some embodiments, when the absorbent fabric 1 is wet under a pressure of 10 kPa, the stiffness retention rate of the absorbent fabric 1 is ≥90%.

[0097] The stiffness retention rate of the absorbent fabric 1 is ≥90%, indicating that the absorbent fabric 1 can still effectively resist bending deformation and maintain the stability of its overall shape under wet conditions. This high stiffness retention rate reduces the possibility of the connecting fiber 40 losing its supporting function due to moisture absorption and softening, and reduces the risk of the first substrate 10 and the second substrate 20 becoming too close together or misaligned under pressure, thereby maintaining the structural integrity and ventilation efficiency of the airflow channel 30 of the absorbent fabric 1.

[0098] In some embodiments, under a pressure of 10 kPa, the thickness reduction rate M of the absorbent fabric 1 in the dry state is ≤20%.

[0099] The thickness reduction rate M ≤ 20% when the absorbent fabric 1 is in a dry state reflects the compressibility of the absorbent fabric 1 under dry conditions. The low thickness reduction rate indicates that the connecting fiber 40 has sufficient rigidity to effectively resist compression under pressure, reducing the possibility of excessive deformation of the connecting fiber 40 causing the airflow channel 30 to be squeezed and narrowed. This allows the absorbent fabric 1 to maintain low wind resistance and high ventilation during long-term use.

[0100] The second aspect of this application also provides a water storage component 2, which includes an absorbent fabric 1 and a water-guiding mesh 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.

[0101] The first substrate 10 and the second substrate 20 in the absorbent fabric 1 are arranged along the thickness direction of the absorbent fabric 1, and the first substrate 10 and the second substrate 20 are enclosed along the length direction to form a cylindrical water storage mesh 200. The water guiding mesh 210 covers the axial end of the water storage mesh 200.

[0102] 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 in the water storage mesh 200 to evaporate effectively.

[0103] like Figure 6 As shown, the water-guiding mesh covers at least a portion of the outer end of the water storage mesh 200 along its axial direction. That is, the water-guiding mesh covers at least a portion of the end face of the water storage mesh 200.

[0104] The water-guiding mesh covers the end face of the water-storing mesh 200, thus fixing at least part of the edge of the water-storing mesh 200 and achieving an edge-sealing effect. The water-guiding mesh provides structural support to the ends 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 easily creates gaps at the edges, the water-guiding mesh wraps 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 the water-guiding effect of the water-storing component 2.

[0105] In addition, the water-guiding mesh has good air permeability and permeability. The liquid first contacts the water-guiding mesh and then enters the water-storage mesh 200. When the liquid flows through the water-guiding mesh, it undergoes permeation and diffusion, which improves the uniformity of liquid distribution. This allows the water-guiding mesh 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.

[0106] The water-guiding mesh is a fabric, which is a woven material or textile. 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. Its surface 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 .

[0107] Water-guiding mesh can be single-layered or double-layered. When using a single-layered structure, the water-guiding mesh is made of PET polyester with a thickness of less than 2mm, thus possessing thin, breathable, and easily permeable properties. When using a double-layered structure, the upper layer of the water-guiding mesh 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.

[0108] In some embodiments, the height of the water storage net 200 is H1, and the height of the water guiding net along the axial direction of the water storage net 200 is H2, wherein H2≤0.2H1.

[0109] H2≤0.2H1 ensures that the water-guiding mesh provides sufficient sealing and water-guiding functions without excessively covering the effective evaporation area of ​​the water storage mesh 200. By controlling the height of the water-guiding mesh 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 mesh at the edges achieves the dual functions of uniform water distribution and structural reinforcement.

[0110] In some embodiments, the height of the water storage net 200 is H1, and the height of the water guiding net along the axial direction of the water storage net 200 is H2, where 1cm≤H2≤3cm.

[0111] H2≥1cm ensures that the water-guiding mesh has sufficient coverage area to achieve effective edge sealing and water guiding functions, thus wrapping the 200mm edge gap of the water storage mesh.

[0112] If H2≤3cm, the risk of excessive water guide net height affecting the main evaporation performance of the water storage net 200 is reduced, while the amount of water guide net used and production cost are controlled.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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 coordinated with the effective evaporation interface, which helps to improve the gas-liquid exchange efficiency.

[0117] 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, adjusting the fan speed can better adapt to their water retention characteristics and evaporation requirements.

[0118] 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 effective 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 load on the high-density fiber structure, while preventing the adhesion problem of the connecting fibers 40 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.

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.
