Abstract

This application discloses a fiber mesh fabric, a textile, a three-dimensional fabric, and a humidification device. The fiber mesh fabric includes a first base layer, a second base layer, and first connecting fibers. The weight ratio of the first connecting fibers to the fiber mesh fabric is greater than the weight ratio of the first base layer to the second base layer. This allows for a larger specific surface area from the increased number of first connecting fibers, enhancing moisture adsorption and storage capacity to meet long-term humidification needs. It also improves gas-liquid contact efficiency and humidification capacity as airflow passes through the fiber mesh fabric. Furthermore, the greater number of fibers and larger specific surface area per unit volume efficiently captures impurities in gases or fluids, improving the cleanliness of the humidified gas. Simultaneously, the first connecting fibers form a uniform and stable support between the first and second base layers.

Description

Technical Field

[0001] This application relates to the field of humidifier technology, and more particularly to a fiber mesh, fabric, three-dimensional fabric, and humidification device. Background Technology

[0002] A humidifier comprises a fan assembly, a spray nozzle, and a three-dimensional fabric. The spray nozzle sprays water onto the three-dimensional fabric, wetting the fiber mesh within it. The fan assembly blows air onto the fiber mesh; the air passes over the mesh, causing the water on it to evaporate. The evaporated water vapor is then blown out of the humidifier to humidify the external space. The performance of the fiber mesh significantly affects the humidification effect of the humidifier. Developing a fiber mesh with more uniform moisture distribution, structural stability, and strong impurity adsorption capacity is a challenge the industry needs to address. Utility Model Content

[0014] In one feasible implementation, the coverage of the first base layer and the second base layer is 20%-50%.

[0015] According to a second aspect of the embodiments of this application, a fabric is provided, comprising a fiber mesh as described in any of the above technical solutions, the fabric being formed by laminating at least two layers of the fiber mesh.

[0035] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0037] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0038] like Figure 1 As shown in the embodiment of this application, a fiber mesh fabric is proposed, wherein the fiber mesh fabric 1 includes:

[0039] First grassroots level 11;

[0040] The second base layer 12 is provided with the first base layer 11 and the second base layer 12 spaced apart;

[0041] The first connecting fiber 13 is disposed between the first base layer 11 and the second base layer 12, and the first connecting fiber 13 is used to connect the first base layer 11 and the second base layer 12.

[0042] The weight ratio of the first connecting fiber 13 to the fiber mesh 1 is the first ratio, the weight ratio of the first base layer 11 to the fiber mesh 1 is the second ratio, and the weight ratio of the second base layer 12 to the fiber mesh 1 is the third ratio. The first ratio is greater than the second ratio, and the first ratio is greater than the third ratio.

[0043] The fiber mesh fabric 1 provided in this embodiment includes a first base layer 11, a second base layer 12, and a first connecting fiber 13. The first base layer 11 and the second base layer 12 are spaced apart to form a three-dimensional space. The first connecting fiber 13 is used to connect the first base layer 11 and the second base layer 12. The weight ratio of the first connecting fiber 13 to the fiber mesh fabric 1 is greater than the weight ratio of the first base layer 11 to the fiber mesh fabric 1 and the weight ratio of the second base layer 12 to the fiber mesh fabric 1. Based on this, during the use of the humidifier, more first connecting fibers 13 can provide a larger specific surface area, which can enhance the water adsorption capacity and water storage capacity. It can meet the needs of long-term humidification and increase the gas-liquid contact efficiency when the airflow passes through the fiber mesh 1, thereby increasing the humidification capacity. Moreover, by using more fibers per unit volume and a larger specific surface area, it can efficiently capture impurities in the gas or fluid through inertial collision, diffusion deposition, and interception effects, thereby improving the cleanliness of the humidified gas. At the same time, the first connecting fiber 13 can form a stable support between the first base layer 11 and the second base layer 12, which can reduce the situation of insufficient spacing caused by insufficient number of first connecting fibers 13 in some areas. During water storage and ventilation, the fiber mesh 1 can maintain a stable state.

[0044] It is understood that the first connecting fiber 13 can be a linear structure, a curved structure, or a spiral structure. By forming a spiral shape through the first connecting fiber 13, the contact efficiency between air and water can be improved to maintain the stability of the air passage, and the surface area can be increased to retain more water.

[0045] Understandably, a textured hydrophilic layer (not shown in the figure) can be formed on the surface of the first connecting fiber 13. Multiple textured structures can be formed on the surface of the first connecting fiber 13. This textured hydrophilic layer increases the roughness of the surface of the first connecting fiber 13, intercepting some fine particles and impurities in the water. Water droplets are less likely to remain on the textured hydrophilic layer, allowing water to be converted into water vapor more evenly. The first connecting fiber 13 has a larger surface area, allowing water to evaporate more efficiently, resulting in higher humidification efficiency.

[0046] It is understandable that the first connecting fiber 13 can be made of resin fibers such as nylon fiber and polyester fiber, which have good formability and softness, and while having a certain water absorption, it can maintain a stable state of structure between the first base layer 11 and the second base layer 12.

[0047] like Figure 1 As shown, in one feasible implementation, the first ratio is between 41% and 62%.

[0048] In this technical solution, by limiting the first ratio, the first connecting fiber 13 can form a stable three-dimensional support structure between the first base layer 11 and the second base layer 12, while maximizing the water storage and impurity adsorption capacity of the first connecting fiber 13, reducing scale formation, and improving humidification cleanliness. In filtration scenarios, it can balance impurity interception efficiency and airflow resistance, reducing equipment energy consumption while maintaining filtration effect. For example, when the weight ratio of the first base layer 11 to the first connecting fiber 13 and the second base layer 12 is 24:52:24, the water storage capacity of the first connecting fiber 13 can be significantly improved, and the evaporation efficiency of the first base layer 11 and the second base layer 12 can also be significantly improved. Thus, it can be seen that under the same water volume and air volume, as the weight of the first connecting fiber 13 increases, the water storage capacity and evaporation efficiency of the fiber mesh 1 show a synchronous increasing trend.

[0049] like Figure 1 As shown, in one feasible embodiment, a first opening 14 is provided on the first base layer 11, and a second opening 15 is provided on the second base layer 12. At least a portion of the first opening 14 is correspondingly provided with the second opening 15, and a first connecting fiber 13 is connected between the outer edge of the first opening 14 and the outer edge of the second opening 15.

[0050] In this technical solution, a first opening 14 is formed on the first base layer 11, and a second opening 15 is formed on the second base layer 12. The shape of the first opening 14 may be the same as or different from the shape of the second opening 15. At least a portion of the first opening 14 corresponds to the second opening 15, and a first connecting fiber 13 connects the outer edges of the first opening 14 and the second opening 15. The first connecting fiber 13 is disposed at the outer edges of the first opening 14 and the second opening 15, providing an installation position for the first connecting fiber 13, thus making the connection between the first connecting fiber 13 and the first base layer 11 and the second base layer 12 more stable. Along the direction of water vapor flow, the first opening 14 and the second opening 15 may partially overlap, forming a flow channel between them. Water vapor flows from the first opening 14 through the flow channel and towards the second opening 15. At least a portion of the structure of the first connecting fiber 13 may be located within the flow channel. There may be multiple first openings 14 and multiple second openings 15. At least some of the plurality of first openings 14 may correspond to a second opening 15.

[0051] Multiple first openings 14 and multiple second openings 15 can be provided on the outer edge of the first opening 14 and the outer edge of the second opening 15, respectively. The shapes of the multiple first openings 14 can be the same or different. The shapes of the multiple second openings 15 can be the same or different. A first connecting fiber 13 can be threaded between the first openings 14 and the second openings 15. Multiple first openings 14 are connected sequentially, and the first connecting fiber 13 can be threaded through the overlapping portion of two adjacent first openings 14. Multiple second openings 15 are connected sequentially, and the first connecting fiber 13 can be threaded between two adjacent second openings 15. The provision of the first opening 14 increases the surface area of ​​the first base layer 11, resulting in better humidification. The provision of the second opening 15 increases the surface area of ​​the second base layer 12, resulting in better humidification. The threading of the first connecting fiber 13 between the first openings 14 and the second openings 15 makes the overall structure of the fiber mesh 1 more stable. The correspondence between the first openings 14 and the second openings 15, as well as the connection method between the first connecting fiber 13 and the outer edges of the first openings 14 and the second openings 15, can be adjusted as needed to meet different requirements. The humidification can be adjusted according to the airflow velocity provided by the blower, the viscosity of the water provided to the first base layer 11 and the second base layer 12, the required humidification amount, and the thickness of the first connecting fiber 13.

[0052] like Figure 1 As shown, in one feasible embodiment, the diameter or longest diagonal length of the first opening 14 is not less than 2 mm; and / or the diameter or longest diagonal length of the second opening 15 is not less than 2 mm.

[0053] In this technical solution, the first opening 14 and the second opening 15 can be similar to a circular or hexagonal structure. When the first opening 14 and the second opening 15 are circular through holes, the diameter of the circle is greater than or equal to 2 mm. When the first opening 14 and the second opening 15 are polygonal through holes, the longest diagonal of the polygon is greater than or equal to 2 mm, and the diagonal of the polygon is the distance between the two endpoints. When the polygon is a triangle, the longest diagonal of the polygon is the longest side length of the triangle. By limiting the minimum threshold of the vent holes on the fiber mesh 1, the size of the first opening 14 and the second opening 15 is limited to a reasonable range, reducing the problem of liquid forming a film and blocking the openings due to the first opening 14 and the second opening 15 being too small, suppressing the increase in pressure loss during liquid supply, improving the flow state of the first opening 14 and the second opening 15, improving the air permeability of the fiber mesh 1, and thus improving the humidification effect of the fiber mesh 1.

[0054] like Figure 1 As shown, in one feasible implementation, the coverage of the first base layer 11 and the second base layer 12 is 20%-50%.

[0055] In this technical solution, the coverage rate refers to the proportion of the area covered by the first base layer 11 and the second base layer 12 within a unit area of ​​the fiber mesh fabric 1. For example, when the weight ratio of the first base layer 11 to the first connecting fiber 13 and the second base layer 12 is 24:52:24, a 15mm opening is made on the first base layer 11 and the second base layer 12. 2 The single-hole area is increased to 46,500 holes / m². 2 Given the mesh density, the mesh area within 1 square meter of fiber mesh fabric is 46500*15mm. 2 =0.6975m 2 The coverage rate is 100% - 69.75% = 30.25% (within the 20%-50% range). By limiting the coverage rate of the first base layer 11 and the second base layer 12 to 20%-50%, the lower limit of the 20% coverage rate ensures the support capacity of the first base layer 11 and the second base layer 12 for the fiber mesh fabric 1, which can stably fix the two ends of the first connecting fiber 13. The upper limit of the 50% coverage rate reserves functional space for the fiber mesh fabric 1, allowing fluids such as water or air to smoothly penetrate the second base layer 12 and come into contact with the first connecting fiber 13, ensuring the air permeability and water permeability of the fiber mesh fabric 1. For example, in the humidification scenario, water can quickly penetrate to the first connecting fiber 13, and in the filtration scenario, airflow can pass through efficiently. At the same time, the first connecting fiber 13 can also efficiently capture impurities. By enhancing the overall structural support of the fiber mesh fabric 1 through reasonable fiber distribution, its structural stability and resistance to deformation are effectively improved. The lightweight first base layer 11 and second base layer 12, due to their low fiber density and permeable structure, can accelerate the penetration efficiency of water on the surface of the fiber mesh fabric 1, providing a prerequisite for subsequent transmission. Meanwhile, the high-density first connecting fiber 13, with its denser fiber arrangement, can form a continuous water adsorption and conduction channel, maintaining sufficient water storage capacity, and ultimately comprehensively improving the water storage, evaporation, air permeability and structural stability of the fiber mesh fabric 1.

[0056] The second aspect of this application provides a fabric 2, including the fiber mesh 1 provided in any of the first aspect embodiments described above. The fabric 2 is formed by laminating at least two layers of fiber mesh 1. Since the fabric 2 includes the fiber mesh 1, the beneficial effects of the fiber mesh 1 already explained will not be repeated in this application.

[0057] The multi-layer fiber mesh fabric 1 in the fabric 2 is stacked along the thickness direction of the fabric 2. When stacking the multi-layer fiber mesh fabric 1, the multi-layer fiber mesh fabric 1 can be aligned between the first openings 14 or staggered between the first openings 14.

[0058] like Figure 2 , 3As shown in Figures 4 and 5, a third aspect of the present application provides a three-dimensional fabric 3, which includes the fabric 2 provided in the second aspect embodiment above, and an edge-sealing fabric 4, which at least covers a portion of the end of the fabric 2 in the height direction.

[0059] In this technical solution, the edge-sealing fabric 4 covers at least a portion of the end of the fabric 2 in the height direction. By covering the end face of the fabric 2, the edge-sealing fabric 4 can fix at least a portion of the edge of the fabric 2, thereby achieving an edge-sealing effect. The edge-sealing fabric 4 provides structural support for the end of the fabric 2, improving the stability of the fabric 2's shape, reducing deformation or collapse, and ensuring sufficient contact area between the fabric 2 and airflow and water flow. This results in uniform local water absorption and ventilation, thereby improving the fabric 2's moisture retention and evaporation effects. Furthermore, the structural shape of the fabric 2 easily creates gaps at the edges; the edge-sealing fabric 4 can wrap around the edges of the fabric 2, making the edges of the three-dimensional fabric 3 smoother, increasing the contact area between the three-dimensional fabric 3 and the water cross-section of the drain opening, and improving the water-guiding effect of the three-dimensional fabric 3. In addition, the edge sealing fabric 4 has good air permeability and permeability. The liquid first comes into contact with the edge sealing fabric 4 and then enters the fabric 2. When the liquid flows through the edge sealing fabric 4, it undergoes penetration and diffusion, which improves the uniformity of liquid distribution. This allows the edge sealing fabric 4 to play a role in evenly distributing water to the fabric 2 below, thus optimizing the water absorption effect of the fabric 2.

[0060] The edge-sealing fabric 4 covers the three-dimensional fabric 3 in two directions, which improves the support strength of the edge-sealing fabric 4 for the fabric 2 and further enhances the stability of the fabric 2's shape, thereby improving the moisture retention and evaporation effects of the fabric 2. Furthermore, the edge-sealing fabric 4 is bent and covers the ends of the fabric 2, making it easier to fix the edge-sealing fabric 4 to the fabric 2 and facilitating the workers' edge-sewing operations on the fabric 2.

[0061] It is understood that the fabric 2 may be a tubular structure, with the edge-sealing fabric 4 covering the top and / or bottom of the fabric 2.

[0062] It is understandable that the material hardness of the edge-sealing fabric 4 is greater than or equal to the material hardness of the fabric 2. The material of the edge-sealing fabric 4 can be thermoplastic polyester or saturated polyester, such as polyester resin.

[0063] It is understandable that, such as Figure 2 In the diagram, the thickness direction of fabric 2 is the X direction, and the height direction of fabric 2 is the Y direction.

[0064] like Figure 2 As shown, in one feasible embodiment, the edge-sealing fabric 4 covers the fabric 2 along the height direction of the fabric 2 for a length of 1mm-3mm, and the ratio of the thickness of the edge-sealing fabric 4 to the thickness of the fabric 2 is less than or equal to 20%.

[0065] In this technical solution, by limiting the length of the edge sealing fabric 4 covering the fabric 2 in the height direction, the coverage range of the edge sealing fabric 4 on the outer edge of the fabric 2 is limited, so that the edge sealing fabric 4 extends on the fabric 2 to a position 1cm to 3cm away from the end face, so that the wrapping range of the edge sealing fabric 4 is within a reasonable range, to prevent the coverage range of the edge sealing fabric 4 from being too small, resulting in weak support strength of the edge sealing fabric 4, and also to prevent the coverage range of the edge sealing fabric 4 from being too large, resulting in the edge sealing fabric 4 affecting the contact between the fabric 2 and the airflow and water flow. The ratio of the thickness of the back side of the edge-sealing fabric 4 to that of the fabric 2 is less than or equal to 20%. By limiting the thickness of the edge-sealing fabric 4, it is made relatively thin. The thinner shape improves the breathability and permeability of the edge-sealing fabric 4. In terms of breathability, the thinner edge-sealing fabric 4 has a looser fiber interlacing density, and the airflow channels formed inside are smoother, which can effectively reduce the resistance when the airflow passes through. In terms of permeability, the water penetration path of the thin edge-sealing fabric 4 is shorter, and the fiber gaps are more likely to form efficient capillary channels. Whether water is supplied by spraying or absorbed from the bottom, after water comes into contact with the edge-sealing fabric 4, it can quickly penetrate the thin structure of the edge-sealing fabric 4 and penetrate into the fabric 2. This reduces the problem of water accumulation on the surface, slow penetration, or even dripping and wasting due to excessive edge-sealing thickness. It can reduce the situation where excessive water accumulation forms a water film that blocks the airflow channels, and also reduce the problem of insufficient water causing the airflow to blow dry. Ultimately, it makes the humidification of the three-dimensional fabric 3 more stable and the humidification range more uniform, thus improving the humidification effect of the three-dimensional fabric 3.

[0066] like Figure 3 As shown, in one feasible embodiment, the edge sealing fabric 4 is a single-layer structure, the thickness of the edge sealing fabric 4 is less than 2mm, and the edge sealing fabric 4 has a first mesh.

[0067] In this technical solution, when the edge sealing fabric 4 is a single-layer structure, the thickness of the edge sealing fabric 4 is less than 2mm. By limiting the thickness of the edge sealing fabric 4 to less than 2mm, the edge sealing fabric 4 is relatively thin, which improves the air permeability and permeability of the edge sealing fabric 4, enabling uniform water distribution to the fabric 2, thereby improving the humidification effect of the three-dimensional fabric 3. Moreover, when the edge sealing fabric 4 is a single layer, a small first mesh is opened on the single-layer structure, which further improves the water permeability.

[0068] like Figure 4 As shown, in one feasible embodiment, the edge sealing fabric 4 has a multi-layer structure, including a first weave layer 41, a second weave layer 42, and a second connecting fiber 43. The first weave layer 41 is disposed outside the second weave layer 42, and the two ends of the second connecting fiber 43 are respectively connected to the first weave layer 41 and the second weave layer 42. A second mesh 44 is provided on the first weave layer 41, and a third mesh 45 is provided on the second weave layer 42. The diameter or the longest diagonal length of the second mesh 44 is greater than the diameter or the longest diagonal length of the third mesh 45.

[0069] In this technical solution, when the edge-sealing fabric 4 has a multi-layer structure, the first layer 41 of the edge-sealing fabric 4 is stacked on the outside of the second layer 42, so that the edge-sealing fabric 4 forms a multi-layer structure. The first layer 41 and the second layer 42 together wrap the top or bottom outer end of the three-dimensional fabric 3, which improves the overall structural strength of the three-dimensional fabric and the support effect on the three-dimensional fabric 3. There can be multiple second connecting fibers 43. The second connecting fibers 43 are located between the first layer 41 and the second layer 42. The second connecting fibers 43 connect the first layer 41 and the second layer 42, further improving the structural lightness of the edge-sealing fabric 4. In addition, the second connecting fibers 43 can store and guide the liquid flowing through the first layer 41 and the second layer 42, improving the flow guiding efficiency and seepage uniformity of the edge-sealing fabric 4.

[0070] In this technical solution, the first weave layer 41 is further defined to have a second mesh 44, and the second weave layer 42 is defined to have a third mesh 45. The second mesh 44 and the third mesh 45 can be similar to circular or hexagonal structures. When the second mesh 44 and the third mesh 45 are circular, the diameter of the second mesh 44 is greater than the diameter of the third mesh 45. When the second mesh 44 and the third mesh 45 are polygonal structures, the longest diagonal of the second mesh 44 is greater than the longest diagonal of the third mesh 45. By defining the edge-sealing fabric 4 as a multi-layer structure, with the diameter or longest diagonal of the second mesh 44 on the outer first weave layer 41 being greater than that of the third mesh 45 on the inner second weave layer 42, the liquid permeation effect of the inner layer fabric is greater than that of the outer layer fabric. This allows the fluid to quickly penetrate into the inner layer fabric after flowing through the outer layer fabric, further improving the liquid permeation efficiency of the edge-sealing fabric 4 and reducing the accumulation of liquid in the edge-sealing fabric 4.

[0071] Understandably, the second mesh size is 8 to 12 times larger than the third mesh size.

[0072] A fourth aspect of the present application provides a humidification device, comprising: a fiber mesh 1 as provided in any of the first aspect embodiments above; a fabric 2 as provided in the second aspect embodiments above; or a three-dimensional fabric 3 as provided in any of the third aspect embodiments above.

[0073] The humidification device provided in this application embodiment includes fiber mesh 1, fabric 2, or three-dimensional fabric 3 as described in any of the above technical solutions. Therefore, the humidification device has the beneficial effects of the fiber mesh 1, fabric 2, or three-dimensional fabric 3 described in the above technical solutions, which will not be elaborated here.

[0074] In this utility model, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "install," "connect," "join," and "fix" should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "join" can be a direct connection or an indirect connection through an intermediate medium.
