Description

Technical Field

[0001] This utility model relates to a water-retaining fabric, a filter element, and a humidifier. 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 and water retention, resulting in insufficient humidification effect and failing to meet user needs. Utility Model Content

[0013] wherein the at least one first set of holes (102) extends at least one connecting line (300) to the same second set of holes (202);

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

[0015] wherein the length of the at least one connecting line (300) between the first fabric surface (100) and the second fabric surface (200) 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);

[0020] at least part of the surface of the first filament has a first recess;

[0021] the first recess extends along the length of the first filament;

[0022] alternatively, the first recess is a point-like recess;

[0023] wherein at least one of the first fabric thread (110), the second fabric thread (210) and the connecting line (300) further comprises:

On the one hand, the deformation of the weaving thread caused by the pulling of the connection line improves the opening area of the first air port and the second air port, and then the water film affects the airflow flow problem. On the other hand, the shape stability of the connection line extending between the first fabric surface and the second fabric surface is improved, and the connection line will not accumulate and bend due to the deformation of the weaving thread, which occupies the airflow channel between the first air port and the second air port. On the other hand, the deformation of the weaving thread caused by the pulling of the weaving thread improves the overall shape of the water holding fabric, which causes the first air port and the second air port to shift position, and improves the continuous humidification effect.

[0039] To further illustrate the technical means and effects taken by the utility model to achieve the intended utility model purposes, the following describes in detail the specific implementation, structure, features and effects of the water-holding fabric according to the utility model, with reference to the accompanying drawings and examples.

[0040] As shown in Figures 1-6 the utility model embodiment provides a water-holding fabric (10), comprising:

[0041] at least two fabric surfaces, the at least two fabric surfaces being arranged in layers, and the at least two fabric surfaces comprising adjacent first fabric surfaces (100) and second fabric surfaces (200);

[0042] the first fabric surfaces (100) comprise a plurality of first air ports (101), the first air ports (101) being surrounded by a plurality of first weft threads (110) connected in sequence, or being surrounded by a plurality of first weft threads (110) sleeved in sequence, adjacent first weft threads (110) being connected or sleeved to form first sleeve holes (102);

[0043] the second fabric surfaces (200) comprise a plurality of second air ports (201), the second air ports (201) being surrounded by a plurality of second weft threads (210) connected in sequence, or being surrounded by a plurality of second weft threads (210) sleeved in sequence, adjacent second weft threads (210) being connected or sleeved to form second sleeve holes (202);

[0044] connecting threads (300), the connecting threads (300) extending from the first sleeve holes (102) to the second sleeve holes (202) to connect the first fabric surfaces (100) and the second fabric surfaces (200).

[0045] The water-holding fabric (10) can be used in an evaporative humidifier as a filter screen of the evaporative humidifier. In the evaporative humidifier, the water-holding fabric (10) is connected to a support, and the water-holding fabric (10) is wetted by a structure capable of supplying water to the water-holding fabric (10) such as a sprinkler, and the water-holding fabric (10) holds water. An airflow is provided to the water-holding fabric (10) by an airflow driving member such as a blower, and the airflow at least flows from one side of the water-holding fabric (10) to the other side, and then at least passes through the water-holding fabric (10) and carries the water held by the water-holding fabric (10) to be dispersed into the environment to enhance humidification of the environment. In turn, the airflow passing property and the water holding property of the water-holding fabric (10) are two important factors for improving the humidification effect.

[0046] The fabric surface has a certain thickness and is interwoven by weft threads in a linear structure. As shown in Figure 7 the fabric surface can be an arc surface when in use, the fabric surface can be enclosed into a cylindrical shape, or, asFigure 8 The fabric surface can also be flat as shown. The water holding fabric (10) can include multiple fabric surfaces, the structure of any fabric surface can be the same or different. The multiple fabric surfaces are stacked and spaced apart, the distance between the fabric surfaces can be uniform or non-uniform, the distance between the fabric surfaces is increased by the connecting lines (300). The fabric surfaces can be only two, i.e. as shown in Figure 1 The water holding fabric (10) includes a first fabric surface (100) and a second fabric surface (200), or in some other embodiments, the fabric surfaces can be more, which can be set as needed, such as in Figure 1 As shown in the first fabric surface (100) and the second fabric surface (200), 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 including only the first fabric surface (100) and the second fabric surface (200), if more water storage is needed to achieve better humidification effect, it can be as shown in Figure 7 As shown, multiple water holding fabrics (10) are used in close proximity to each other. The edges of the water holding fabrics (10) are stitched or fixed by other means such as welding, etc. Alternatively, as shown in Figure 8 As shown, multiple water holding fabrics (10) are spaced apart. The airflow passes through each water holding fabric (10) in turn, and the water in the airflow is increased by multiple water holding fabrics (10).

[0047] The multiple first air ports (101) of the first fabric surface (100) and the multiple second air ports (201) of the second fabric surface (200) are openings on the fabric surfaces, which are the inlet and outlet for the airflow. The size or shape of the first air ports (101) and the second air ports (201) can be set to be not easy to store water, or in other words, no water film is formed on the first air ports (101) and the second air ports (201), so that the first air ports (101) and the second air ports (201) only serve as a passage, and the water holding fabric (10) has a smooth airflow passage. The size or density of the first air ports (101) and the second air ports (201) can be set as needed, such as according to the airflow flow rate of the humidifier, the material of the first fabric surface (100) and the second fabric surface (200), whether the water used by the humidifier is mixed with a fragrance agent, etc. to set the viscosity of the water. More specific embodiments will be described later.

[0048] The first air port (101) and the second air port (201) are surrounded by the yarns, and are densely arranged on the first fabric surface (100) and the second fabric surface (200). The yarns are connected or sleeved by a plurality of weft threads. The first air port (101) is surrounded by a first weft thread (110), and the second air port (201) is surrounded by a second weft thread (210). A plurality of first weft threads (110) can be formed by a single thin thread continuously surrounding one turn, and a plurality of second weft threads (210) can be formed by a single thin thread continuously surrounding one turn. Figure 1 As shown in FIG. 1, for the first weft thread (110) or the second weft thread (210), not only is it used to surround a single first air port (101) or a single second air port (201). Taking the first weft thread (110) as an example, the adjacent edges of two adjacent first air ports (101) are constituted by the same first weft thread (110), that is, at least part of the first weft thread (110) is used to surround two adjacent first air ports (101). Alternatively, in some embodiments, the first weft thread (110) can also be shared by more first air ports (101), such as three first air ports (101) or four first air ports (101).

[0049] Taking the first air port (101) as an example, the first weft thread (110) is a strip-shaped yarn surrounding a ring structure. For the convenience of description, two adjacent first weft threads (110) are referred to as a front weft thread and a rear weft thread. The connection between the two adjacent first weft threads (110) means that the front weft thread and the rear weft thread pass through each other, and then the rear weft thread will occupy part of the opening of the front weft thread. The space between the rear weft thread and the front weft thread formed in the opening of the front weft thread is referred to as the aforementioned first sleeve hole (102). Alternatively, the first sleeve hole (102) is a region belonging to the opening of the front weft thread and a region belonging to the opening of the rear weft thread, which is a common region of the front weft thread and the rear weft thread. A plurality of first weft threads (110) can be formed by a single thin thread continuously surrounding one turn, and a plurality of second weft threads (210) can be formed by a single thin thread continuously surrounding one turn.

[0050] The connecting line (300) extends from the first set of holes (102) to the second set of holes (202), or vice versa. The connecting line (300) extends between the first fabric surface (100) and the second fabric surface (200), and serves to support the distance between the first fabric surface (100) and the second fabric surface (200), as well as to connect the first fabric surface (100) and the second fabric surface (200). Importantly, the connecting line (300) extending from the first set of holes (102) to the second set of holes (202) serves to hold water in the water-holding fabric (10). In more detail, in the first aspect, the connecting line (300) extending from the first set of holes (102) to the second set of holes (202) serves to transfer water: the connecting line (300) connects the first fabric surface (100) and the second fabric surface (200), acting as a bridge for water transfer between the first fabric surface (100) and the second fabric surface (200), ensuring that water can be effectively transferred from one of the first fabric surface (100) and the second fabric surface (200) to the other. This design allows water to spread and be maintained throughout the water-holding fabric (10) from a water source, such as the location closest to or in contact with the water source, improving the fabric's ability to maintain humidification without drying out. In the second aspect, the connecting line (300) extending from the first set of holes (102) to the second set of holes (202) fixes the first fabric surface (100) and the second fabric surface (200), improving the problem of uneven water distribution caused by deviation: 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 surface (100) and the second fabric surface (200) to be more closely connected. This connection reduces the relative movement of the first fabric surface (100) and the second fabric surface (200), improving the deviation caused by air flow, vibration or water pressure changes during use, improving the uniform distribution of water, and improving the problem of poor air flow caused by deviation. In the third aspect, the connecting line (300) enhances evaporation efficiency and improves the continuous water supply of the water-holding fabric (10): as the connecting line (300) extends from the first set of holes (102) to the second set of holes (202) to improve the continuous flow of water between the first fabric surface (100) and the second fabric surface (200), it 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 allows more water to be effectively evaporated as air flows through the water-holding fabric (10), enhancing the humidification effect. In the fourth aspect, the connecting line (300) extending from the first set of holes (102) to the second set of holes (202) serves to improve the overall strength of the fabric and the stability of the overall structure: the connecting 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.

[0051] 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.

[0052] 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).

[0053] In addition, the first loop (102) is not formed by two first weft threads (110) but can be formed by three or more first weft threads (110) according to the position, and the multiple first weft threads (110) can be formed by a single thread continuously surrounding one round. As shown in Figure 2 three first weft threads (110). The connecting thread (300) passes through the first loop (102) to improve the connection and support of the first fabric surface (100) and the second fabric surface (200) instead of being connected by the first weft thread (110). The first loop (102) is more stable for the mutual loop structure of two or more first weft threads (110), can provide stronger support for the connecting thread (300), and the edge of the first loop (102) is jointly stressed by two or more first weft threads (110), so that the shape of the first loop (102) is not easy to change, thereby the shape, area of the first air port (101) and the shape of the connecting thread (300) can be improved, the preset air passage and water holding capacity will not be greatly reduced due to long-term use. It can be understood that the connecting thread (300) has the same advantages as the foregoing analysis for the second loop (202) and the second weft thread (210).

[0054] It is worth noting that, in order to make the structure clearer, only part of the structure is shown in the present application Figures 1-4 , and only part of the connecting thread (300) is drawn, and the remaining connecting thread (300) can be arranged by referring to the part shown, thereby forming a complete water holding fabric (10).

[0055] The utility model discloses hold water fabric, filter piece and humidifier which are provided by the embodiment of the utility model, mainly through setting first air port (101) and second air port (201), adopt the extension of connecting line (300) between first air port (101) and second air port (201), and connecting line (300) is fixed first weaving surface (100) and second weaving surface (200) by the extension of first sleeve hole (102) to second sleeve hole (202), improve the smooth flow of airflow, improve the problem of airflow circulation resistance caused by water film on hold water fabric, improve the problem of unable effective humidification caused by difficult driving airflow and insufficient flow, simultaneously, through the extension of connecting line between first weaving surface and second weaving surface, provide enough area for the contact of airflow and water through the contact of connecting line and airflow, improve the effective humidification of airflow carrying enough moisture. Through the application, the connecting line is located in the first sleeve hole and the second sleeve hole which are jointly constituted by two weaving threads, and the problem of insufficient weaving thread supporting force caused by the connection of single weaving thread is improved. On the one hand, the problem of insufficient opening area of first air port and second air port caused by the deformation of weaving thread under the pulling of connecting line is improved, and then the problem of water film affecting airflow flow caused by the deformation of weaving thread is improved. On the other hand, the shape stability of the extension of connecting line between first weaving surface and second weaving surface is improved, and the problem of the accumulation and bending of connecting line caused by the deformation of weaving thread is avoided, and the airflow channel between first air port and second air port is not occupied. On the other hand, the problem of the change of the overall shape of hold water fabric caused by the deformation of weaving thread is improved, the problems of the displacement of first air port and second air port and the like are caused, and the problem of the continuous and good humidification effect is improved.

[0056] In an embodiment, two connecting lines (300) extend in the single first sleeve hole (102) and / or the second sleeve hole (202). For example, the two connecting lines (300) can be arranged in the first sleeve hole (102) and / or the second sleeve hole (202) in a parallel manner. Figure 1The single connecting line (300) is shown to pass through the first set of holes (102) and the second set of holes (202) to connect the connecting line (300). Alternatively, in some other embodiments, the connecting line (300) extending from the single first set of holes (102) and / or the second set of holes (202) can be no less than 5, such as 5, 6 or more, so that the number of connecting lines (300) is more, the connecting lines (300) are more dense, and it is easier to form a water film between the connecting lines (300), thereby greatly increasing the amount of water that the connecting lines (300) can hold, increasing the contact area between the airflow and the moisture, and increasing the humidification efficiency under the limited volume of the water-holding fabric. The number of connecting lines (300) can be set according to the ventilation conditions, such as when the air flow is small or the fan speed is low, the number of connecting lines (300) extending from the single first set of holes (102) and / or the second set of holes (202) is not more than 30, thereby on the one hand improving the problem of obstructing airflow circulation caused by the expansion of too many connecting lines (300) into the airflow passage between the first air port (101) and the second air port (201); on the other hand, the number of connecting lines (300) can be set according to the thickness, such as when the connecting line (300) is thick, the wire diameter is ≥80μm, and the number of connecting lines (300) is controlled to be less than 20, which helps to improve the problem of reducing the number of first air ports (101) and second air ports (201) in a limited area caused by the first set of holes (102) and / or the second set of holes (202) being too large; and helps to improve the problem of small contact area between the airflow and the single connecting line (300) caused by too dense connecting lines (300), which leads to the problem of not being able to fully utilize the water held by the connecting lines (300).

[0057] The number of first set of holes (102) and second set of holes (202) can be the same and can be correspondingly arranged, or the number of first set of holes (102) and second set of holes (202) can be different. Each first set of holes (102) can be connected with a connecting line (300), or some first set of holes (102) can be connected with a connecting line (300), such as the first set of holes (102) connected with a connecting line (300), and the middle one or more first set of holes (102) not connected with a connecting line (300), and the last first set of holes (102) connected with a connecting line (300). This arrangement can reduce the number of connections and reduce the difficulty of weaving, and the number of connecting lines (300) connected by the first set of holes (102) can be used to adjust the density of the connecting lines (300). For the second set of holes (202), each second set of holes (202) can be connected with a connecting line (300), or some second set of holes (202) can be connected with a connecting line (300). The following are several connection methods, which can be combined for use.

[0058] The connection between the connection lines (300) and the first and second holes (102, 202) can be as shown in Figure 3 For any connection line (300), the connection line (300) extending from at least one first hole (102) extends to the same second hole (202), that is, the connection line (300) repeatedly passes between the current first hole (102) and the current second hole (202), thereby forming a plurality of connection lines (300) leading from the first hole (102) to the second hole (202). This connection mode can improve the misalignment of the first and second fabrics (100, 200) by limiting the connection line (300), that is, this connection mode can better position the relative positions of the first and second fabrics (100, 200).

[0059] It can also be that the connection line (300) extending from at least one first hole (102) extends to at least two different second holes (202). Alternatively, the connection line (300) extending from at least two first holes (102) extends to the same second hole (202). As shown in Figure 4 To simultaneously use a connection line (300) extending from one first hole (102) to two different second holes (202), the same connection line (300) extending from the same second hole (202) extends into two first holes (102), thereby adjusting the spacing between the connection lines (300) by controlling the number of connection lines (300), forming a small gap between the connection lines (300) to achieve capillary wicking effect, ensuring uniform distribution of water while ensuring continuous conduction of water. The extension length of the connection line (300) can be increased, thereby increasing the water holding capacity of a single connection line (300), and by reasonably setting the spacing between the connection lines (300), the water film formed between the connection lines (300) can be increased, further increasing the water holding capacity of the connection lines (300).

[0060] In addition, the connection line (300) extending from the first hole (102) can extend to more, such as three, second holes (202).

[0061] In one embodiment, the length of at least part of the connecting lines (300) in the area between the first fabric surface (100) and the second fabric surface (200) is greater than the distance between the first fabric surface (100) and the second fabric surface (200), so that the connecting lines (300) are curved between the first fabric surface (100) and the second fabric surface (200). The curved shape of the connecting lines (300) can increase the length of a single connecting line (300), thereby increasing the water holding capacity of the connecting line (300) itself. The flow path of the air flow between the first air port (101) and the second air port (201) can be considered as a curved path, thereby making the path longer and providing more opportunities for the air flow to contact water, further increasing the water holding capacity of the air flow. In addition, the area of the water film formed between adjacent connecting lines (300) can be increased, thereby further increasing the total water holding capacity of multiple connecting lines (300). The connecting lines (300) can be curved in an arc shape, or in some embodiments, the connecting lines (300) can be alternately curved in multiple directions. The connecting lines (300) can also be in a spiral winding shape, i.e. similar to a spring shape, thereby further increasing the water holding capacity of the connecting lines (300).

[0062] Alternatively, at least part of the connecting lines (300) extend in a straight line between the first fabric surface (100) and the second fabric surface (200), thereby increasing the air flow between the first air port (101) and the second air port (201) without being occupied by the connecting lines (300), and reducing the difficulty of weaving the connecting lines (300).

[0063] In one embodiment, the number of first air ports (101) and second air ports (201) is the same, forming corresponding paths of the first air ports (101) and the second air ports (201). The number of first air ports (101) and second air ports (201) can also be different, with one first air port (101) corresponding to multiple second air ports (201) to form a path, or multiple first air ports (101) corresponding to a single second air port (201) to form a path. The size of the first air port (101) and the second air port (201) can be the same or different. For example, the front end of the first air port (101) in the direction of air flow can be smaller than the second air port (201), thereby avoiding the formation of a water film on the second air port (201) due to congestion of air flow containing higher moisture at the second air port (201). Alternatively, the size of the first air port (101) can be greater than the second air port (201), thereby making the air flow channel between the first air port (101) and the second air port (201) appear to be tightening, increasing the pressure of the air flow on the connecting lines (300) between the first air port (101) and the second air port (201), and increasing the contact strength between the air flow and the moisture on the connecting lines (300), making it easier to carry moisture.

[0064] The relative positions of the first air port (101) and the second air port (201) can be various, for example, the face where the first air port (101) is located can be approximately regarded as a plane, and in the direction perpendicular to the plane where the first air port (101) is located, at least part of the projections of the first air port (101) and the second air port (201) coincide, and the higher projection coincidence provides a path for the airflow perpendicular to the plane where the first air port (101) is located, improving the smoothness of the airflow circulation. Alternatively, the first air port (101) and the second air port (201) can also be partially overlapped in the direction perpendicular to the extension plane of the first air port (101), that is, the first air port (101) and the second air port (201) are staggered, thereby providing a path for the airflow inclined to the plane where the first air port (101) is located, increasing the length of the airflow path, the length of the connecting line (300) and the contact time between the airflow and the connecting line (300) in the case of limited distance between the first fabric (100) and the second fabric (200), thereby increasing the water holding capacity of the airflow.

[0065] The shapes of the first air port (101) and the second air port (201) can be various, and the shapes of the first air port (101) and the second air port (201) can be regular circles, ellipses, triangles or polygons, or the shapes of the first air port (101) and the second air port (201) can be irregular, for example, the shape of at least one of the first air port (101) and the second air port (201) is an irregular ellipse, or can be an irregular rectangle as shown in Figure 5 , or can be an irregular hexagon as shown in Figure 6 , and the irregular hexagon can be referred to as a hexagon-like shape. The shapes of the openings of the plurality of first air ports (101) and the plurality of second air ports (201) can be different, for example, a combination of hexagons and triangles.

[0066] The sizes of the different first air ports (101) and second air ports (201), the density of the connecting line (300) and the thickness of the water holding fabric (10) are not independent, but are mutually influenced and cooperatively restricted to the water holding capacity and the water holding effect after the airflow circulation. The following specific data provided by the present application can be used as a reference, and the following data cooperatively achieve a better humidification effect:

[0067] The first air port (101) or the second air port (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 of the hexagon is greater than or equal to 2 mm and less than or equal to 3 mm. If the shape of the air port 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 of any two non-adjacent vertices, and the long diagonal refers to the line segment of any two non-adjacent vertices that is longer than the short diagonal. If the shape of the air port is a circle or an ellipse, the diagonal refers to the line segment connecting any two points on the circle. The chord can be regarded as a kind of "diagonal" of the 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 of any two points that is shorter than the long diagonal. The thickness of the water-holding fabric (10) is greater than or equal to 3 mm and less than or equal to 8 mm. The connection line (300) has a warp density greater than or equal to 30 threads / inch and less than or equal to 36 threads / inch, and a weft density greater than or equal to 24 threads / inch and less than or equal to 26 threads / inch. When multiple water-holding fabrics (10) are used in a stacked manner, the number of layers of the water-holding fabric (10) is less than 4, which improves the problem of excessive wind resistance caused by the difference in position between the layers when the number of layers is too large.

[0068] The single fiber used for spinning into a weaving thread is referred to as a filament, and at least one of the first weaving thread (110), the second weaving thread (210), and the connection line (300) comprises a first filament. Taking the first weaving thread (110) as an example, it can be understood that the following description of the characteristics of the filament in the first weaving thread (110) also applies to the second weaving thread (210) and the connection line (300). The first weaving thread (110) can be tightly woven by a plurality of first filaments, such as 140 to 150 first filaments. In an embodiment, at least part of the surface of the first filament has a first recess. The first recess can extend in the length direction of the first filament, or can extend in the circumferential direction or in a random direction. The recess can be a relatively narrow line, or can be a relatively wide channel. For example, a first recess extending in the length direction of the first filament can be arranged on each surface in the circumferential direction of the first filament, so that the cross section of the first filament in the length direction is a special-shaped cross section, such as a triangle with inwardly recessed sides, or a square with inwardly recessed sides, etc. This helps to increase the water-holding surface area of the first filament, can more effectively hold water, increases the contact area between the airflow and the water, and improves the humidification efficiency. The first recess can also not be a strip-shaped recess, but can be a point-shaped recess, so as to form a rough surface with protrusions and recesses on the surface of the first filament. The formation of the rough surface can rely on physical deposition on the surface of the first filament, so that the surface of the first filament presents a rough shape, which helps to increase the water-holding surface area, can more effectively hold water, increases the contact area between the airflow and the water, and improves the humidification efficiency. The height difference between the protruding part and the recessed part of the rough surface can be greater than 0 microns and less than 100 microns.

[0069] The first recessed shapes of the first filaments included in different first weft threads (110) can be the same, such as the first weft threads (110) being composed of first filaments with the same cross-sectional shape. However, setting different first recessed shapes can cause the first filaments to have different degrees of softness and hardness. In order to improve the strength of the edges of the first air port (101) and take into account better water retention, the first recessed shapes of the first filaments included in different first weft threads (110) can be different, that is, different first weft threads (110) can be woven by using first filaments with different cross-sectional shapes. The first recessed shapes of different first filaments in the same first weft thread (110) can be the same or different, that is, the first weft thread (110) can be woven by a plurality of first filaments with the same cross section in close contact, or the first weft thread (110) can be woven by a plurality of first filaments with different cross sections in close contact.

[0070] In an embodiment, the first weft thread (110) further includes a second filament, and the material of the second filament is different from that of the first filament. The material of the filament can be relatively soft, having better formability, or relatively hard, having better structural strength and not being prone to deformation after long use. The filament itself can have good water absorption, such as being made of cotton material, thereby improving water retention, or the filament itself can not absorb water, but rely on the recesses or roughness on the surface to improve water retention capacity, thereby reducing the accumulation of water scale inside the filament. The strength and water absorption of the first weft thread (110) can be changed as needed by mixing a plurality of different filaments. For example, the first filament can not absorb water and only retain 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.

[0071] In some embodiments, the first weft thread (110) further includes an antibacterial and mildew-proof component, which is embedded between the first filaments or between the first filament and the second filament, that is, the antibacterial and mildew-proof component is added to be woven together with the first filament and the second filament to form the first weft thread (110), so as to improve the problem that the antibacterial and mildew-proof component is easy to fall off after being coated on the first weft thread (110) and increase the process.

[0072] In some embodiments, the first weft thread (110) further includes a hydrophilic factor, which is embedded between the first filaments or between the first filament and the second filament, that is, the hydrophilic factor is added, such as polybutyl acrylate and methyl methacrylate, during the weaving process, so as to improve the problem that the hydrophilic layer is easy to fall off after being coated on the first weft thread (110) and increase the process.

[0073] In addition, in the connecting line (300) can only include a single first filament, then can adopt the way of coating antibacterial mildew-resistant components and hydrophilic factors, improve the performance of the connecting line (300).

[0074] The color of the water holding fabric (10) can be various, such as non-white, such as gray, light brown, yellow, blue and the like. When the dirt and the like are deposited on the water holding fabric (10), it is not easy to show, and the long-term use is not easy to change color, and the uneven yellowing of the water holding fabric (10) caused by hiding dirt is avoided, and the appearance is affected.

[0075] In another aspect, the utility model also provides a filter piece, including at least one water holding fabric (10) of any one of preceding description, water holding fabric (10) can set one or more according to need, water holding fabric (10) can be as Figure 7 As shown, it is enclosed into a cylindrical shape, and it can be as Figure 8 As shown, it is laid flat. When a plurality of water holding fabrics (10) are used, they can be Figure 7 As shown in the multiple water holding fabrics (10) are tightly connected and fixed by sewing, and can be integrally connected to a single fixing frame. It can also be Figure 8 As shown, it is enclosed into a cylindrical shape, and it can be as

[0077] In another aspect, the application also provides a humidifier, which includes the filter piece described above, a support, a water supply mechanism and an airflow pushing mechanism. The filter piece is connected to the support, the water supply mechanism supplies water to the water holding fabric (10) of the filter piece by spraying or the like, so that the water holding fabric (10) holds water. The airflow pushing mechanism provides airflow to the water holding fabric (10) by a blower or the like. The airflow flows from one side of the water holding fabric (10) to the other side, then passes through the water holding fabric (10) and carries the water held by the water holding fabric (10), and is dispersed into the environment to improve the humidification of the environment.

[0078] The humidifier includes at least one of the embodiments of the filter piece described above, and has the advantages of any one of the filter pieces described above, which will not be repeated here.

Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered within the protection scope of the utility model.
