Description

Technical Field

[0001] This invention relates to a water-retaining fabric, a filter element, a humidifier, and a method for processing the water-retaining fabric. Background Technology

[0002] As living standards improve, people have increasingly higher requirements for their daily home environment, and air quality, especially humidity control, has always been a key focus in improving the home environment. Evaporative humidifiers draw water through a filter and use a fan to create airflow that passes through the filter, carrying the water from the filter to the external environment, thus humidifying the surroundings.

[0003] The filter screen mainly functions to retain water. Existing filters usually cannot balance good airflow smoothness and water retention capacity, resulting in insufficient humidification effect and failing to meet user needs. Summary of the Invention

[0004] In view of this, in order to solve at least one of the aforementioned technical problems, the present invention provides a water-retaining fabric, a filter element, a humidifier, and a method for processing the water-retaining fabric.

[0005] To achieve the above objectives, the present invention mainly provides the following technical solutions:

[0006] On one hand, the present invention provides a water-retaining fabric, comprising:

[0007] At least two fabric surfaces, at least two fabric surfaces are stacked, and at least two fabric surfaces include an adjacent first fabric surface (100) and a second fabric surface (200);

[0008] The first fabric (100) includes a plurality of first air vents (101), each air vent (101) being formed by a plurality of first threads (110) connected together, and adjacent first threads (110) forming a first sleeve hole (102) at the connection point;

[0009] The second fabric (200) includes a plurality of second air ports (201), which are formed by a plurality of second threads (210) connected together, and adjacent second threads (210) form a second sleeve hole (202) at the connection point;

[0010] A connecting line (300) extends from the first set of holes (102) to the second set of holes (202) to connect the first fabric (100) and the second fabric (200).

[0011] Two connecting lines (300) extend from a single first set of holes (102) and / or a second set of holes (202);

[0012] Alternatively, the number of connecting lines (300) extending from a single first set of holes (102) and / or second set of holes (202) shall not be less than five.

[0013] In this case, at least one connecting line (300) extending from the first set of holes (102) extends toward the same second set of holes (202);

[0014] And / or, at least one connecting line (300) extending from the first set of holes (102) extends into at least two different second sets of holes (202).

[0015] Wherein, at least a portion of the connecting line (300) has a length in the region between the first fabric surface (100) and the second fabric surface (200) that is greater than the distance between the first fabric surface (100) and the second fabric surface (200), so that the connecting line (300) is curved between the first fabric surface (100) and the second fabric surface (200);

[0016] And / or, at least part of the connecting line (300) extends in a straight line between the first fabric (100) and the second fabric (200).

[0017] The projections of the first air inlet (101) and the second air inlet (201) in the direction perpendicular to the extension surface of the first air inlet (101) coincide;

[0018] And / or, at least one of the first air inlet (101) and the second air inlet (201) is elliptical, rectangular or hexagonal in shape.

[0019] Among them, at least one of the first weaving thread (110), the second weaving thread (210) and the connecting thread (300) includes a first filament;

[0020] At least a portion of the surface of the first filament has a first depression;

[0021] The first depression extends along the length of the first filament;

[0022] Alternatively, the first depression may be a dot-shaped depression;

[0023] Among them, at least one of the first weaving thread (110), the second weaving thread (210), and the connecting thread (300) further includes:

[0024] The second thread is made of a different material than the first thread;

[0025] And / or, when there are multiple first filaments, the antibacterial and antifungal components are embedded between the first filaments;

[0026] And / or, when there are multiple first filaments, the hydrophilic factor is embedded between the first filaments.

[0027] On the other hand, the present invention also provides a filter element comprising at least one water-retaining fabric (10) of any of the above, wherein when there are multiple water-retaining fabrics (10), the multiple water-retaining fabrics (10) are stacked and connected, or are arranged at intervals.

[0028] In another aspect, the present invention also provides a humidifier, including the aforementioned filter element or including at least one of the aforementioned water-retaining fabrics (10).

[0029] In another aspect, the present invention also provides a method for processing water-retaining fabrics, comprising:

[0030] The first weaving threads are connected to form a first weaving surface with multiple first air vents. The first air vents are surrounded by multiple first weaving threads, and adjacent first weaving threads are connected to form a first set of holes.

[0031] The second weaving threads are connected to form a second weaving surface with multiple second air vents. The second air vents are surrounded by multiple second weaving threads, and adjacent second weaving threads are connected to form a second set of holes.

[0032] The connecting wire is led out from the first set of holes and extended to the second set of holes to connect the first fabric and the second fabric.

[0033] The water-retaining fabric, filter element, humidifier, and water-retaining fabric processing method proposed in this invention mainly improve airflow smoothness by setting a first air inlet and a second air inlet, thus addressing the problems of high airflow resistance caused by the water film on the water-retaining fabric, difficulty in driving airflow, and ineffective humidification due to insufficient flow. Simultaneously, the extension of the connecting line between the first and second fabric surfaces provides sufficient contact area between the airflow and water, enhancing the effective humidification by allowing the airflow to carry enough moisture. This application improves the yarn support force caused by connecting to a single yarn by placing the connecting line within the first set of holes formed by two yarns and the second set of holes formed by two yarns. On the one hand, it reduces the problem of the opening area of ​​the first and second air vents being affected by the deformation of the yarn under the tension of the connecting line, which in turn leads to water film affecting airflow. On the other hand, it improves the shape stability of the connecting line extending between the first and second fabric surfaces, preventing the connecting line from piling up and bending due to yarn deformation under tension, thus avoiding the obstruction of the airflow channel between the first and second air vents. Furthermore, it improves the overall shape change of the water-retaining fabric caused by the deformation of the yarn under tension, which leads to the misalignment of the first and second air vents, thereby improving the continuous humidification effect.

[0043] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description, in conjunction with the accompanying drawings and embodiments, describes the specific implementation, structure, features and effects of a water-retaining fabric proposed according to the present invention.

[0044] On the one hand, such as Figure 1-6 As shown, an embodiment of the present invention provides a water-retaining fabric (10), comprising:

[0045] At least two fabric surfaces, at least two fabric surfaces are stacked, and at least two fabric surfaces include an adjacent first fabric surface (100) and a second fabric surface (200);

[0046] The first fabric (100) includes a plurality of first air ports (101), which are formed by a plurality of first threads (110) connected in sequence or wrapped around each other. Adjacent first threads (110) are connected or wrapped around each other to form a first hole (102).

[0047] The second fabric (200) includes a plurality of second air ports (201), which are formed by a plurality of second fabric threads (210) connected in sequence or wrapped around each other. Adjacent second fabric threads (210) are connected or wrapped to form a second sleeve hole (202).

[0048] A connecting line (300) extends from the first set of holes (102) to the second set of holes (202) to connect the first fabric (100) and the second fabric (200).

[0049] Water-retaining fabric (10) can be used in evaporative humidifiers as a filter. In an evaporative humidifier, the water-retaining fabric (10) is attached to a support and wetted by a structure such as a spray nozzle, which supplies water to the water-retaining fabric (10), allowing it to retain moisture. Airflow is supplied to the water-retaining fabric (10) by an airflow-driven component such as a blower. The airflow flows from at least one side of the water-retaining fabric (10) to the other side, passes through the water-retaining fabric (10), and carries the moisture held on the water-retaining fabric (10) into the environment, thus enhancing humidification. Therefore, the airflow permeability and water retention of the water-retaining fabric (10) are two important factors for improving humidification efficiency.

[0050] The fabric has a certain thickness and is made of interwoven linear yarns. For example... Figure 7 As shown, the fabric can be curved when in use, or it can be formed into a cylindrical shape, or, as... Figure 8 As shown, the fabric surface can also be planar. The water-retaining fabric (10) can include multiple fabric surfaces, and the structure of any fabric surface can be the same or different. Multiple fabric surfaces are stacked and spaced apart, and the distance between the fabric surfaces can be uniform or non-uniform. The distance between the fabric surfaces is increased by connecting lines (300). There can be only two fabric surfaces, i.e., as shown in the figure. Figure 1 As shown, it includes a first fabric surface (100) and a second fabric surface (200). Alternatively, in some other embodiments, there may be more fabric surfaces, which can be set as needed, such as in... Figure 1 Based on the first fabric surface (100) and the second fabric surface (200) shown, a third fabric surface, a fourth fabric surface, etc., are also provided on the side of the first fabric surface (100) opposite to the second fabric surface (200). In the embodiment that only includes the first fabric surface (100) and the second fabric surface (200), if a larger water storage capacity is required to achieve a better humidification effect, it can be as follows: Figure 7 As shown, multiple water-retaining fabrics (10) are used in close layers, and the edges of the water-retaining fabrics (10) are sewn together or fixed by means such as welding. Alternatively, it can be done as follows: Figure 8 As shown, multiple water-holding fabrics (10) are arranged at intervals. The airflow passes through each water-holding fabric (10) in sequence, and the airflow comes into contact with the water-holding fabrics (10) multiple times, thereby increasing the moisture content of the airflow.

[0051] The plurality of first air vents (101) on the first fabric (100) and the plurality of second air vents (201) on the second fabric (200) are openings on the fabric, serving as inlets and outlets for airflow. The size or shape of the first air vents (101) and the second air vents (201) can be configured to prevent water from accumulating or to prevent water film formation on the first air vents (101) and the second air vents (201), so that the first air vents (101) and the second air vents (201) only serve as channels, improving the smooth airflow channel of the water-holding fabric (10). The size or density of the first air vents (101) and the second air vents (201) can be set as needed, such as according to the airflow rate of the humidifier, the material of the first fabric (100) and the second fabric (200), and whether the water used in the humidifier is mixed with substances such as fragrances, resulting in high water viscosity. More specific embodiments will be described later.

[0052] The first air vent (101) and the second air vent (201) are formed by weaving and enclosing the silk fabric, densely arranged on the first fabric surface (100) and the second fabric surface (200). Weaving involves connecting or interlocking multiple threads. The first air vent (101) is formed by a loop of first threads (110), and the second air vent (201) is formed by a loop of second threads (210). Multiple first threads (110) can be formed by continuously wrapping a single fine thread around the entire surface, and multiple second threads (210) can be formed by continuously wrapping a single fine thread around the entire surface. For example... Figure 1 As shown, the first thread (110) or the second thread (210) is not only used to enclose a single first air vent (101) or a single second air vent (201). Taking the first thread (110) as an example, the adjacent sides of two adjacent first air vents (101) are formed by the same first thread (110), that is, at least a portion of the first thread (110) is used to enclose two adjacent first air vents (101). Alternatively, in some embodiments, the first thread (110) can also be shared by more first air vents (101), such as three first air vents (101) or four first air vents (101).

[0053] Taking the first air vent (101) as an example, the first weaving thread (110) is a ring structure formed by strips of filament. For ease of explanation, two adjacent first weaving threads (110) are referred to as the front weaving thread and the back weaving thread. The connection between two adjacent first weaving threads (110) refers to the front weaving thread and the back weaving thread passing through each other. Then, the back weaving thread will occupy a part of the opening area of ​​the front weaving thread. The space between the back weaving thread and the front weaving thread formed in the opening of the front weaving thread is called the aforementioned first set of holes (102). Alternatively, it can be said that the first set of holes (102) is the area that belongs to both the opening of the front weaving thread and the opening of the back weaving thread. It is a common area of ​​the front weaving thread and the back weaving thread. Multiple first weaving threads (110) can be formed by continuously wrapping around a single fine thread. Multiple second weaving threads (210) can be formed by continuously wrapping around a single fine thread.

[0054] The connecting line (300) extends from the first set of holes (102) to the second set of holes (202), or conversely, from the second set of holes (202) to the first set of holes (102). The connecting line (300) extends between the first fabric surface (100) and the second fabric surface (200). This extension of the connecting line (300) from the first set of holes (102) to the second set of holes (202) serves to support the distance between the first fabric surface (100) and the second fabric surface (200), and also to connect the first fabric surface (100) and the second fabric surface (200). Importantly, the extension of the connecting line (300) from the first set of holes (102) to the second set of holes (202) contributes to the water-holding function of the water-holding fabric (10). In detail, firstly, the connecting line (300) extends from the first set of holes (102) to the second set of holes (202) to serve as a moisture transfer mechanism: the connecting line (300) connects the first fabric surface (100) and the second fabric surface (200), acting as a bridge for moisture transfer between the first fabric surface (100) and the second fabric surface (200), enabling moisture to be effectively transferred from one of the first fabric surface (100) to the other. This design allows moisture to diffuse and remain throughout the water-retaining fabric (10) from a water source, such as the location of the water-retaining fabric (10) closest to or in contact with a water source, thus improving the fabric's ability to retain moisture even when dry. Secondly, the connecting line (300) extends from the first socket (102) to the second socket (202) to fix the first fabric (100) and the second fabric (200), improving the problem of uneven moisture distribution caused by misalignment: the connecting line (300) forms a strong and direct connection between the first socket (102) and the second socket (202), allowing the first fabric (100) and the second fabric (200) to be more tightly bonded together. This connection reduces the relative movement between the first fabric (100) and the second fabric (200), improves the misalignment caused by airflow, vibration, or water pressure changes during use, improves the uniform distribution of moisture, and improves the problem of poor airflow caused by misalignment. Thirdly, the connecting line (300) enhances evaporation efficiency and improves the continuous water supply of the water-holding fabric (10): Since the connecting line (300) extends from the first set of holes (102) to the second set of holes (202), it improves the continuous flow of water between the first fabric surface (100) and the second fabric surface (200), which can continuously increase the humidity of the first fabric surface (100) and the second fabric surface (200), thereby increasing the evaporation area. This continuous water supply and relatively balanced water distribution enable more water to evaporate effectively when the airflow passes through the water-holding fabric (10), enhancing the humidification effect. Fourthly, the connecting line (300) extending from the first set of holes (102) to the second set of holes (202) improves the overall strength of the fabric and enhances the overall structural stability: The connection form of the connecting line (300) enhances the overall structural strength of the water-holding fabric (10).During long-term humidification and airflow, this strength can prevent the water-holding fabric (10) from twisting or being damaged by the weight of water and airflow. Even in environments with high humidity and strong airflow, the connection method of the connecting line (300) allows the water-holding fabric (10) to maintain its shape to a certain extent when working effectively. At the same time, it prevents deformation caused by pulling the water-holding fabric (10) during washing and disassembly, thereby improving durability and reducing the risk of wear and tear and a decrease in humidification effect. The stable structure helps maintain the long-term performance of the humidifier.

[0055] Through the action of external wind power components such as blowers, centrifugal fans, and axial fans, the airflow will pass through the first air inlet (101) and the second air inlet (201), and come into contact with the moisture held on the connecting line (300) between the first air inlet (101) and the second air inlet (201). This reduces the pressure loss of the airflow passing through the first fabric (100) and the second fabric (200), and also reduces the noise caused by the impact of the airflow with the first fabric (100) and the second fabric (200). At the same time, the connecting line (300) holds a large amount of moisture, increasing the water contact area on the airflow path and improving the contact efficiency between the airflow and water. After the airflow passes through the water-holding fabric (10), it will have sufficient humidity. The connecting line (300) itself will store water, and by setting multiple connecting lines (300), a water film will also be formed between the connecting lines (300), which will further increase the amount of water that the airflow can contact, greatly increasing the water holding efficiency.

[0056] The connecting wires (300) can be connected in various ways. For example, a single connecting wire (300) can be threaded through or through the first set of holes (102) to form two connecting wires (300) extending from the first set of holes (102), or the connecting wires (300) can be threaded through or through the second set of holes (202) to form two connecting wires (300) extending from the second set of holes (202). Figure 1 As shown, the connecting wires (300) can be connected by sequentially passing through the previous first set of holes (102), the previous second set of holes (202), the next first set of holes (102), and the next second set of holes (202), thereby achieving simple weaving and high structural strength. In some other embodiments, the connecting wires (300) can also be led out from the first set of holes (102) or the second set of holes (202) by bonding. As in the aforementioned embodiment where the connecting wires (300) pass through the first set of holes (102), only an even number of connecting wires (300) can be led out from the first set of holes (102). However, by bonding, such as by ultrasonic welding, an odd number or an even number of connecting wires (300) can be led out from the first set of holes (102).

[0057] Furthermore, the first set of holes (102) is not merely formed by the intersection of two first threads (110), but may be formed by the intersection of three or more first threads (110), depending on their position. Multiple first threads (110) can be formed by a single thread continuously looping around the perimeter. For example... Figure 2 As shown, a first socket (102) is formed by the interlocking of three first threads (110). A connecting line (300) passes through the first socket (102) to improve the connection and support between the first fabric (100) and the second fabric (200), rather than connecting them through the first threads (110). The first socket (102) provides a more stable interlocking structure for two or more first threads (110), and provides stronger support for the connecting line (300). The edge of the first socket (102) is subjected to the combined force of two or more first threads (110), thus the shape of the first socket (102) is less prone to change. This allows for improvements in the shape and area of ​​the first air vent (101) and the shape of the connecting line (300), ensuring that the preset ventilation and water holding capacity do not decline significantly over time. It can be understood that the connecting line (300) has the same advantages as the second socket (202) and the second thread (210) as described above.

[0058] It is worth noting that, in order to make the structure more clearly represented in the diagram, this application... Figure 1-4 Only a portion of the structure is shown, and only a portion of the connecting lines (300) are drawn. The remaining connecting lines (300) can be referenced to the shown portion to form a complete water-retaining fabric (10).

[0059] The water-holding fabric, filter element, and humidifier proposed in this invention embodiment mainly improve airflow by setting a first air inlet (101) and a second air inlet (201), and using a connecting line (300) extending between the first air inlet (101) and the second air inlet (201). The connecting line (300) extends from the first sleeve hole (102) to the second sleeve hole (202) to fix the first fabric surface (100) and the second fabric surface (200), thereby improving airflow smoothness and alleviating the problem of high airflow resistance caused by the water film on the water-holding fabric. This also improves the problem of ineffective humidification caused by difficulty in driving airflow and insufficient flow rate. At the same time, by extending the connecting line between the first and second fabric surfaces, the contact between the connecting line and the airflow provides sufficient contact area for the airflow and water, improving the airflow's ability to carry sufficient moisture for effective humidification. This application addresses the problem of insufficient yarn support caused by connecting to a single yarn by placing the connecting line within the first and second sets of holes formed by two yarns. On one hand, it improves the problem of insufficient opening area of ​​the first and second air vents due to yarn deformation under the pull of the connecting line, which in turn leads to water film affecting airflow. On the other hand, it improves the shape stability of the connecting line extending between the first and second fabric surfaces, preventing the connecting line from piling up and bending due to yarn deformation under tension, thus avoiding obstruction of the airflow channel between the first and second air vents. Furthermore, it improves the overall shape change of the water-retaining fabric caused by yarn deformation under tension, which could lead to misalignment of the first and second air vents, thereby improving the continuous and better humidification effect.

[0060] In one embodiment, two connecting wires (300) extend from a single first set of holes (102) and / or a second set of holes (202). For example, as can be used... Figure 1The connecting wires (300) shown are connected by passing through the first set of holes (102) and the second set of holes (202). Alternatively, in some other embodiments, there may be no fewer than 5 connecting wires (300) extending from a single first set of holes (102) and / or second set of holes (202), such as 5, 6 or more, thereby increasing the number of connecting wires (300) and making them denser. This makes it easier to form a water film between the connecting wires (300), thereby greatly increasing the amount of water that the connecting wires (300) can hold, increasing the contact area between airflow and moisture, and increasing humidification efficiency within a limited volume of water-holding fabric. The number of connecting wires (300) can be set according to the ventilation conditions. For example, when the airflow is small or the fan speed is low, the number of connecting wires (300) extending from a single first set of holes (102) and / or second set of holes (202) should not exceed 30. This will improve the problem of excessive connecting wires (300) expanding into the airflow passage between the first air port (101) and the second air port (201), thus preventing airflow obstruction. On the other hand, the number of connecting wires (300) can be set according to their thickness. When the connecting wire (300) is thicker, with a wire diameter of ≥80μm, and the number of connecting wires (300) is controlled to be less than 20, it helps to improve the problem of the reduction in the number of first air ports (101) and second air ports (201) in a limited area due to the first set of holes (102) and / or the second set of holes (202) being too large; it also helps to improve the problem of the small contact area between the airflow and a single connecting wire (300) caused by the connecting wires (300) being too dense, which leads to the inability to fully utilize the moisture held by the connecting wires (300).

[0061] The number of first set holes (102) and second set holes (202) can be the same and can be set accordingly, or the number of first set holes (102) and second set holes (202) can be different. Each first set hole (102) can be connected with a connecting line (300), or some first set holes (102) can be connected with connecting lines (300). For example, the first first set hole (102) is connected with a connecting line (300), while one or more first set holes (102) in between are not connected with connecting lines (300), and the next first set hole (102) is connected with connecting lines (300). This setting can reduce the number of connections, reduce the difficulty of weaving, and the density of connecting lines (300) can be adjusted by the number of connecting lines (300) connected to the first set hole (102). For the second set of holes (202), each second set of holes (202) may be connected with a connecting wire (300), or some of the second set of holes (202) may be connected with a connecting wire (300). The following are some examples of connection methods. It can be understood that the following connection methods can be used in combination.

[0062] The connection of the connecting wire (300) between the first socket (102) and the second socket (202) can be as follows: Figure 3 As shown, for any connecting line (300), at least one connecting line (300) extending from the first set hole (102) extends toward the same second set hole (202), that is, the connecting line (300) repeatedly passes between the current first set hole (102) and the current second set hole (202), thereby forming multiple connecting lines (300) introduced from the first set hole (102) to the second set hole (202). This connection method can improve the misalignment problem of the first fabric (100) and the second fabric (200) through the limiting energy of the connecting line (300), that is, this connection method can better position the relative position of the first fabric (100) and the second fabric (200).

[0063] Alternatively, a connecting line (300) extending from at least one first set of holes (102) may extend into at least two different second sets of holes (202). Or, at least two connecting lines (300) extending from the first set of holes (102) may extend into the same second set of holes (202). Figure 4 As shown, a connecting line (300) extending from a first set of holes (102) extends into two different second sets of holes (202) simultaneously, and a connecting line (300) extending from the same second set of holes (202) extends into two first sets of holes (102). The number of connecting lines (300) can be controlled to adjust the interval between the connecting lines (300). The connecting lines (300) form tiny gaps with each other, which can achieve a capillary wicking effect. This achieves uniform water distribution and continuous water conduction. The extension length of the connecting line (300) can be increased, thereby increasing the water holding capacity of a single connecting line (300). Furthermore, by reasonably setting the interval between the connecting lines (300), it is helpful to increase the water film formed between the connecting lines (300), further increasing the water holding capacity of the connecting lines (300).

[0064] In addition, the connecting line (300) extending from the first set of holes (102) can extend to more, such as three second sets of holes (202).

[0065] In one embodiment, at least a portion of the connecting lines (300) have a length greater than the distance between the first fabric surface (100) and the second fabric surface (200) in the region between them, such that the connecting lines (300) are curved between the first fabric surface (100) and the second fabric surface (200). This curved shape of the connecting lines (300) increases the length of a single connecting line (300), thereby increasing the water-holding capacity of the connecting line (300). This can be seen as the airflow path between the first air inlet (101) and the second air inlet (201) being a curved path, resulting in a longer path and more opportunities for contact with water, further increasing the water-holding capacity of the airflow. It also increases the area of ​​the water film formed between adjacent connecting lines (300), thereby further increasing the total water-holding capacity of multiple connecting lines (300). The connecting line (300) can be curved, or in some embodiments, the connecting line (300) can be bent alternately in multiple directions, or the connecting line (300) can be spirally coiled, i.e., like a spring, thereby further increasing the water holding capacity of the connecting line (300).

[0066] Alternatively, at least part of the connecting line (300) extends in a straight line between the first fabric (100) and the second fabric (200), thereby increasing the airflow between the first air inlet (101) and the second air inlet (201) without the connecting line (300) occupying the airflow between the first air inlet (101) and the second air inlet (201), and reducing the difficulty of weaving the connecting line (300).

[0067] In one embodiment, the number of first air inlets (101) and second air inlets (201) is the same, forming a passage corresponding to the first air inlets (101) and the second air inlets (201). The number of first air inlets (101) and second air inlets (201) can also be different; one first air inlet (101) can correspond to multiple second air inlets (201) to form a passage, or multiple first air inlets (101) can correspond to a single second air inlet (201) to form a passage. The sizes of the first air inlets (101) and the second air inlets (201) can be the same or different. For example, the first air inlet (101) can be located at the leading edge in the airflow direction, and its size is smaller than that of the second air inlet (201), thereby improving the formation of a water film on the second air inlet (201) caused by congestion of the airflow containing high moisture content at the second air inlet (201). Alternatively, the size of the first air inlet (101) may be larger than that of the second air inlet (201), which causes the airflow channel between the first air inlet (101) and the second air inlet (201) to tend to tighten. This increases the pressure of the airflow on the connecting line (300) between the first air inlet (101) and the second air inlet (201), making the contact strength between the airflow and the moisture on the connecting line (300) stronger and easier to carry moisture.

[0068] The relative positions of the first air inlet (101) and the second air inlet (201) can be varied. For example, the surface where the first air inlet (101) is located can be approximated as a plane. In the direction perpendicular to the plane where the first air inlet (101) is located, at least part of the projections of the first air inlet (101) and the second air inlet (201) overlap. The higher projection overlap provides a passage for airflow perpendicular to the plane where the first air inlet (101) is located, thereby improving the smoothness of airflow. Alternatively, the projections of the first air inlet (101) and the second air inlet (201) in the direction perpendicular to the extension surface of the first air inlet (101) may overlap, that is, the first air inlet (101) and the second air inlet (201) may be staggered, thereby providing an airflow path inclined to the plane where the first air inlet (101) is located. When the distance between the first fabric (100) and the second fabric (200) is limited, the length of the airflow path is increased, the length of the connecting line (300) is extended, and the contact time between the airflow and the connecting line (300) is extended, thereby increasing the water holding capacity of the airflow.

[0069] The shapes of the first air inlet (101) and the second air inlet (201) can be various. The shapes of the first air inlet (101) and the second air inlet (201) can be regular circles, ellipses, triangles, or polygons. Alternatively, the shapes of the first air inlet (101) and the second air inlet (201) can be irregular, such as at least one of the first air inlet (101) and the second air inlet (201) being an irregular ellipse, or they can be as follows: Figure 5 The irregular rectangle shown, or it could be like... Figure 6 The irregular hexagon shown can be called a quasi-hexagon. The shapes of the openings of the multiple first air ports (101) and multiple second air ports (201) can be different, for example, a combination of hexagons and triangles.

[0070] The different sizes of the first air inlet (101) and the second air inlet (201), the density of the connecting line (300), and the thickness of the water-retaining fabric (10) are not independent entities, but rather interact and synergistically constrain the water retention capacity and the water retention effect after airflow. This application provides the following specific data for reference, which synergistically achieve a better humidification effect:

[0071] The first air vent (101) or the second air vent (201) is hexagonal. The length of the long diagonal of the hexagon is greater than or equal to 3 mm and less than or equal to 5 mm, and the length of the short diagonal is greater than or equal to 2 mm and less than or equal to 3 mm. If the shape of the air vent is a polygon, the diagonal refers to the line segment connecting any two non-adjacent vertices of the polygon, the short diagonal refers to the shortest line segment connecting any two non-adjacent vertices, and the long diagonal refers to the line segment longer than the short diagonal connecting any two non-adjacent vertices. If the shape of the air vent is circular or elliptical, the diagonal refers to the line segment connecting any two points on the circle. A chord can be considered as a kind of "diagonal" of a circle. The long diagonal refers to the longest chord of the circle or ellipse, i.e., the diameter, and the short diagonal refers to the line segment shorter than any two points of the long diagonal. The thickness of the water-retaining fabric (10) is greater than or equal to 3 mm and less than or equal to 8 mm. The density of the connecting thread (300) is greater than or equal to 30 threads / inch and less than or equal to 36 threads / inch, and the weft density is greater than or equal to 24 threads / inch and less than or equal to 26 threads / inch. When multiple water-retaining fabrics (10) are used in combination, the number of layers of water-retaining fabric (10) is less than 4, which improves the problem of excessive wind resistance caused by the superposition of positional differences between layers when there are too many layers.

[0072] The single fiber used to weave into a yarn is referred to as a filament. At least one of the first yarn (110), the second yarn (210), and the connecting thread (300) includes a first filament. Taking the first yarn (110) as an example, it can be understood that the following description of the characteristics of the filament in the first yarn (110) also applies to the second yarn (210) and the connecting thread (300). The first yarn (110) may be woven together from multiple first filaments, such as 140 to 150 first filaments. In one embodiment, at least a portion of the surface of the first filament has a first depression. The first depression may be a depression extending along the length of the first filament, or a depression extending in a circumferential or random direction. The depression may be a narrow ridge or a wide groove. For example, a first recess extending along the length of the first filament can be provided on each surface along the circumference of the first filament, resulting in an irregular cross-section along the length of the first filament, such as a triangle or a square with each side concave inwards. This helps increase the water-holding surface area of ​​the first filament, enabling more effective water retention, increasing the contact area between airflow and water, and improving humidification efficiency. The first recess does not have to be a strip shape; it can be a dot shape, thus forming an uneven, rough surface on the surface of the first filament. The rough surface can be formed by physical deposition on the surface of the first filament, making the surface uneven, which helps increase the water-holding surface area, enabling more effective water retention, increasing the contact area between airflow and water, and improving humidification efficiency. The height difference between the raised portion and the recessed portion of the rough surface can be greater than 0 micrometers and less than 100 micrometers.

[0073] The first recesses of the first filaments included in different first yarns (110) may have the same shape, such as first yarns (110) composed of first filaments with the same cross-sectional shape. However, setting different first recesses may result in the first filaments having different degrees of softness and hardness. In order to improve the strength of the edge of the first air vent (101) and to take into account better water retention, the first recesses of the first filaments included in different first yarns (110) may have different shapes, that is, first filaments with different cross-sectional shapes may be used to weave different first yarns (110). The first recesses of different first filaments in the same first yarn (110) may have the same or different shapes. That is, the first yarn (110) may be composed of multiple first filaments with the same cross-section closely woven together, or it may be composed of multiple first filaments with different cross-sections closely woven together.

[0074] In one embodiment, the first yarn (110) further includes a second filament, which is made of a different material than the first filament. The filament can be made of a softer material with better formability, or it can be made of a harder material with better structural strength and less susceptibility to deformation over time. The filament itself can have good water absorption, such as using cotton material to improve water retention, or it can be non-absorbent, relying on surface depressions or roughness to improve water retention and reduce scale buildup inside the filament. The strength and water absorption of the first yarn (110) can be changed as needed by mixing various different filaments. For example, the first filament can be non-absorbent, only retaining water on the surface, while the second filament absorbs water; or the hardness of the first filament can be greater than that of the second filament.

[0075] In some embodiments, the first yarn (110) also includes an antibacterial and antifungal component. The antibacterial and antifungal component is embedded between the first filaments or between the first filament and the second filament. That is, when the first yarn (110) is woven together from multiple first filaments or the first filament and the second filament, the antibacterial and antifungal component is added and woven together with the first filament and the second filament. The addition of the embedded component improves the disadvantages of the antibacterial and antifungal component being easy to fall off after the first yarn (110) is formed and the increase of the process.

[0076] In some embodiments, the first yarn (110) also includes a hydrophilic factor embedded between the first filaments or between the first filament and the second filament. That is, when multiple first filaments or the first filament and the second filament are woven together to form the first yarn (110), the hydrophilic factor is added. For example, polybutyl acrylate, methyl methacrylate, etc. can be added during the weaving process. The addition of embedded components improves the disadvantages of easy peeling off of the hydrophilic layer after the formation of the first yarn (110) and the increase of the process.

[0077] Furthermore, if the connecting line (300) consists of only a single first filament, the performance of the connecting line (300) can be improved by coating it with antibacterial and antifungal ingredients and hydrophilic factors.

[0078] The water-retaining fabric (10) can be in various colors, such as non-white, gray, light brown, yellow, blue, etc. When scale and other impurities are deposited on the water-retaining fabric (10), they are not easily visible, thus preventing discoloration over time and improving the uneven yellowing of the water-retaining fabric (10) caused by dirt accumulation, which affects its appearance.

[0079] On the other hand, the present invention also provides a filter element comprising at least one water-retaining fabric (10) of any one of the above-mentioned methods. One or more water-retaining fabrics (10) may be provided as needed. The water-retaining fabric (10) may be as follows: Figure 7 As shown, it can be formed into a cylindrical shape, or it can be like... Figure 8 As shown, it is laid flat. When multiple water-retaining fabrics (10) are used, it can be laid as follows: Figure 7 Multiple water-retaining fabrics (10) are tightly joined together and fixed with seams, allowing them to be seamlessly fitted onto a single mounting frame. Alternatively, they can be arranged as follows: Figure 8 The units are spaced apart and each uses a fixed device.

[0080] The filter element includes any of the aforementioned water-retaining fabric (10) embodiments, and the advantages of including any of the aforementioned water-retaining fabric (10) embodiments are not repeated here.

[0081] Furthermore, this application also provides a humidifier, including the aforementioned filter element, as well as a support, a water supply mechanism, and an airflow driving mechanism. The filter element is connected to the support, and the water supply mechanism supplies water to the water-holding fabric (10) of the filter element by spraying or the like, so that the water-holding fabric (10) holds water. The airflow driving mechanism provides airflow to the water-holding fabric (10) by a blower or the like. The airflow flows from at least one side of the water-holding fabric (10) to the other side, passes through the water-holding fabric (10), and carries the moisture held on the water-holding fabric (10) into the environment, thereby increasing the humidification of the environment.

[0082] The humidifier includes embodiments of at least one filter element of any of the above, and the advantages of including any of the above filters will not be elaborated here.

[0083] On the other hand, such as Figure 9 As shown, the present invention also provides a method for processing water-retaining fabrics, which can be used to process water-retaining fabrics forming any of the above embodiments, the method comprising:

[0084] S1. Connect the first threads (110) to form a first fabric (100) with multiple first air vents (101). The first air vents (101) are formed by connecting or surrounding multiple first threads (110). Adjacent first threads (110) are connected or sleeved to form a first sleeve hole (102).

[0085] S2. The second weaving threads (210) are connected to form a second weaving surface (200) with multiple second air ports (201). The second air ports (201) are formed by connecting or surrounding multiple second weaving threads (210). Adjacent second weaving threads (210) are connected or sleeved to form a second sleeve hole (202).

[0086] At least one of the first yarn (110) and the second yarn (210) is a filament composed of a single or multiple first filaments. In some embodiments, at least one of the first yarn (110) and the second yarn (210) further includes a second filament of a different material from the first filament, a hydrophilic agent, and / or an antibacterial and antifungal component, which are woven together with the first filament to form the first yarn (110) and / or the second yarn (210). The first fabric surface (100) and the second fabric surface (200) can be formed in the same way. Taking the first fabric surface (100) as an example, a web loom can be used to form the first yarn (110) by winding the filaments into a loop. The first fabric surface (100) with multiple first air vents (101) is formed by connecting or sequentially nesting the first yarns (110). The size of the first air vent (101) can be changed by altering the length of the first thread (110) or the number of first threads (110) surrounding the first air vent (101). The shape of the first air vent (101) can be changed by varying the connection relationship and placement of the multiple first threads (110), thus improving the problem of water film formation on the first air vent (101) and the second air vent (201). For example... Figure 1 As shown, the first thread (110) or the second thread (210) is not only used to enclose a single first air vent (101) or a single second air vent (201). Taking the first thread (110) as an example, the adjacent sides of two adjacent first air vents (101) are formed by the same first thread (110), that is, at least a portion of the first thread (110) is used to enclose two adjacent first air vents (101). Alternatively, in some embodiments, the first thread (110) can also be shared by more first air vents (101), such as three first air vents (101) or four first air vents (101).

[0087] The connection between two adjacent first threads (110) and the adjacent second threads (210) is either a connection or a loop, and the connection or loop will form a hole at the connection point. Taking the first air vent (101) as an example, for ease of explanation, the two adjacent first threads (110) are referred to as the front thread and the back thread. The looping between the two adjacent first threads (110) means that the front thread and the back thread pass through each other, and then the back thread occupies a part of the opening area of ​​the front thread. The space between the back thread and the front thread formed in the opening of the front thread is called the aforementioned first loop hole (102). Or it can be said that the first loop hole (102) is the area that belongs to both the opening of the front thread and the opening of the back thread, and is the common area of ​​the front thread and the back thread. In addition, the first loop hole (102) is not only formed by the looping and intersection of two first threads (110), but may be formed by the looping and intersection of three or more first threads (110) depending on the position, such as Figure 2 As shown, the first set of holes (102) is formed by the intersection of three first threads (110).

[0088] The above textile process may only form the first fabric surface (100) and the second fabric surface (200), or it may form more fabric surfaces, such as the third fabric surface, the fourth fabric surface, the fifth fabric surface, etc.

[0089] S3. Lead the connecting wire (300) out from the first hole (102) and extend it to the second hole (202) to connect the first fabric (100) and the second fabric (200).

[0090] The connecting line (300) is a filament composed of one or more first filaments. In some embodiments, the connecting line (300) also includes a second filament, hydrophilic agent and / or antibacterial and antifungal component that are different from the first filament, and is woven together with the first filament to form the connecting line (300).

[0091] After forming the first fabric surface (100), the second fabric surface (200), or even more fabric surfaces, multiple fabric surfaces are stacked and connected. Taking the fabric surface as only including the first fabric surface (100) and the second fabric surface (200) as an example, the first fabric surface (100) and the second fabric surface (200) are stacked and spaced apart. The distance between the first fabric surface (100) and the second fabric surface (200) can be uniform or non-uniform. The size of the distance can be determined comprehensively based on the humidification requirements, the viscosity of the water, the mesh size, and the number of connecting lines (300). The connecting wire (300) can extend from the first socket (102) to the second socket (202) in various ways. For example, it can be formed by a single connecting wire (300) passing through the first socket (102) to create two connecting wires (300) extending from the first socket (102), and the connecting wire (300) passing through the second socket (202) to create two connecting wires (300) extending from the second socket (202). Figure 1 As shown, the connection can be achieved by the connecting wire (300) passing sequentially through the previous first set hole (102), the previous second set hole (202), the next first set hole (102), and the next second set hole (202). That is, a single connecting wire (300) can connect multiple first set holes (102) and second set holes (202). For the entire first fabric (100) and second fabric (200), only one connecting wire (300) can be used. Alternatively, a single connecting wire (300) can be used for a certain number of first air vents (101) and second air vents (201), such as a single connecting wire (300) for every ten rows of first air vents (101). Using a connecting wire (300) reduces the number of times the connecting wire (300) passes through the first set hole (102) and second set hole (202), resulting in a simpler structure, easier weaving, easier manufacturing, and lower costs. In some other embodiments, the connecting wires (300) can be led out from the first set of holes (102) or the second set of holes (202) by bonding. As in the aforementioned embodiment where the connecting wires (300) pass through the first set of holes (102), only an even number of connecting wires (300) can be led out from the first set of holes (102). However, by bonding, such as by ultrasonic welding, an odd or even number of connecting wires (300) can be led out from the first set of holes (102).

[0092] The connecting line (300) passes through the first set of holes (102) and the second set of holes (202), connecting and supporting the first fabric surface (100) and the second fabric surface (200) and the spacing between them, rather than being connected through the first thread (110). Utilizing the first set of holes (102) to connect two or more first threads (110) to each other or to form a more stable loop structure provides stronger support for the connecting line (300). The edge of the first set of holes (102) is subjected to the combined force of two or more first threads (110), thus the shape of the first set of holes (102) is less prone to change. This allows for improvements in the shape and area of ​​the first air vent (101) and the shape of the connecting line (300), ensuring that the preset ventilation and water holding capacity do not decline significantly due to prolonged use. It can be understood that the connecting line (300) has the same advantages as the second set of holes (202) and the second thread (210) as analyzed above.

[0093] This application embodiment connects and supports the fabric by providing connecting lines (300) on the first fabric surface (100) and the second fabric surface (200). Firstly, the connecting lines (300) extend from the first sleeve hole (102) to the second sleeve hole (202) to facilitate moisture transfer: the connecting lines (300) connect the first fabric surface (100) and the second fabric surface (200) from the first sleeve hole (102) to the second sleeve hole (202), acting as a bridge for moisture transfer between the first fabric surface (100) and the second fabric surface (200), enabling effective transfer of moisture from one fabric surface (100) to the other. This design allows moisture to diffuse and remain throughout the water-retaining fabric (10) from a water source, such as the location of the water-retaining fabric (10) closest to or in contact with a water source, thus improving the problem of the fabric losing its humidifying ability due to dryness. Secondly, the connecting lines (300) enhance evaporation efficiency and improve the continuous water supply of the water-holding fabric (10): because the connecting lines (300) enable continuous flow of water between the first fabric surface (100) and the second fabric surface (200), they can continuously increase the humidity of the first fabric surface (100) and the second fabric surface (200), thereby increasing the evaporation area. This continuous water supply and relatively balanced water distribution enable more water to evaporate effectively when the airflow passes through the water-holding fabric (10), enhancing the humidification effect. Thirdly, the connecting lines (300) improve the overall strength of the fabric and enhance the overall structural stability: the connection form of the connecting lines (300) enhances the overall structural strength of the water-holding fabric (10). During prolonged humidification and airflow, this strength prevents the water-holding fabric (10) from twisting or being damaged by the weight of moisture and airflow. Even in environments with high humidity and strong airflow, the connection method of the connecting line (300) allows the water-holding fabric (10) to maintain its shape to a certain extent during effective operation. It also prevents deformation caused by pulling on the water-holding fabric (10) during washing and disassembly, thereby improving durability and reducing the risk of wear and tear and decreased humidification effect. The stable structure helps maintain the long-term performance of the humidifier. Fourthly, fixing the first fabric (100) and the second fabric (200) improves the uneven moisture distribution caused by misalignment: the connecting line (300) forms a strong and direct connection between the first set of holes (102) and the second set of holes (202), allowing the first fabric (100) and the second fabric (200) to be more tightly bonded together. This connection reduces the relative movement between the first fabric (100) and the second fabric (200), improves the problem of offset caused by airflow, vibration or water pressure changes during use, improves the uniform distribution of moisture, and helps to improve the poor airflow caused by offset.

[0094] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
