[0041] The humidifying filter element of the present utility model includes a filter element main body 1 and a limiting mesh cloth 2. Among them, the filter element main body 1 has a water flow channel and an air flow channel that are connected. The limiting mesh cloth 2 covering the surface of the filter element main body 1 has a water inlet side, a water outlet side, an air inlet side, and an air outlet side. The water inlet side covers the water inlet end of the water flow channel, so that the water inlet side is connected to the water inlet end of the water flow channel. The water outlet side covers the water outlet end of the water flow channel, so that the water outlet side is connected to the water outlet end of the water flow channel. The air inlet side covers the air inlet end of the air flow channel, so that the air inlet side is connected to the air inlet end of the air flow channel. The air outlet side covers the air outlet end of the air flow channel, so that the air outlet side is connected to the air outlet end of the air flow channel. External water liquid can enter the water flow channel from the water inlet side and then flow out from the water outlet side. At the same time, external air enters the air flow channel from the air inlet side under the action of an external air moving device (such as a fan) and then is ejected from the air outlet side, realizing the humidification of the air and also achieving the effect of purifying the air. The moist and clean air is sent into the room under the action of the air moving device, thereby increasing the environmental humidity. Among them, based on the fact that the filter element main body 1 is made of a textile material, and the material of the limiting mesh cloth 2 also belongs to the textile material, the performance of the humidifying filter element is similar to that of clothing and can be reused. When the humidifying filter element is dirty or has an odor, the humidifying filter element can be hand-washed or washed by a washing machine, avoiding the yellowing and stinking of the humidifying filter element. At the same time, there is no need to directly discard and replace the humidifying filter element when it turns yellow and stinks, reducing waste, being able to reduce the use cost and being more energy-saving and environmentally friendly. In addition, the filter element main body 1 made of a textile material is a fibrous structure, has a good guiding effect, can guide the water liquid to flow smoothly on the water flow channel, and has a strong water absorption and water storage capacity, which can improve the humidifying efficiency of the humidifying filter element. In addition, the filter element main body 1 made of a textile material has more meshes or pores, has a natural air flow channel, has a lower air resistance, and has a larger air output when matching an air moving device of the same power. Therefore, the water vapor carried out with the air volume is also larger, which can increase the humidifying amount and has better humidifying performance than traditional humidifying filter elements. In addition, the limiting mesh cloth 2 can limit the lateral movement and vertical movement of the filter element main body 1, can ensure the relative stability of the lateral position and vertical position of the filter element main body 1, keep the filter element main body 1 stably in its original shape, so that the filter element main body 1 will not undergo obvious deformation or thread breakage after being washed by a washing machine many times, and the structural stability of the humidifying filter element is higher, which is more convenient for the disassembly and assembly of the humidifying filter element.

[0042] Among them, it can be understood that the filter element main body 1 is a fluffy textile material. The filter element main body 1 made of the fluffy textile material has a strong water absorption capacity, can improve the humidifying efficiency. At the same time, the filter element main body 1 made of the fluffy textile material also provides a natural water flow channel and air flow channel.

[0043] It can be understood that the water flow channels are composed of a plurality of mesh holes on the filter element body 1. The plurality of mesh holes are arranged in sequence along the water flow direction and are connected in sequence, and the number of water flow channels is multiple; the air flow channels are also composed of a plurality of mesh holes on the filter element body 1. The plurality of mesh holes are arranged in sequence along the air flow direction and are connected in sequence, and the number of air flow channels is multiple.

[0044] It can be understood that the water inlet side, the water outlet side, the air inlet side, and the air outlet side are all mesh holes on the limiting mesh cloth 2, and the number of the water inlet side, the water outlet side, the air inlet side, and the air outlet side is multiple.

[0045] See Figure 4 , in one embodiment, the number of the filter element bodies 1 is at least two to further enhance the water absorption and water storage capacity of the humidifying filter element, so as to further improve the wetting efficiency of the humidifying filter element.

[0046] See Figures 1-2 , in one embodiment, the filter element body 1 is arranged around the vertical center line of the humidifying filter element, so that the humidifying filter element is formed into an annular structure, which is convenient for inserting the humidifying filter element onto the plastic structural member. At the same time, the humidifying filter element with the annular structure has a larger cross-sectional area, which can further improve the wetting efficiency.

[0047] In other embodiments, the filter element body 1 can also be a structure with a rectangular, polygonal or other irregular cross-section.

[0048] See Figure 1 and Figure 4 , in one embodiment, the limiting mesh cloth 2 includes:

[0049] The outer horizontal limiting mesh cloth 21 is coated on the outer side wall of the filter element body 1, and the outer horizontal limiting mesh cloth 21 forms the air inlet side;

[0050] The inner horizontal limiting mesh cloth 22 is coated on the inner side wall of the filter element body 1, and the inner horizontal limiting mesh cloth 22 forms the air outlet side;

[0051] The upper vertical limiting mesh cloth 23 is coated on the top of the filter element body 1, the upper end of the outer horizontal limiting mesh cloth 21, and the upper end of the inner horizontal limiting mesh cloth 22. The outer side of the upper vertical limiting mesh cloth 23 is connected to the upper end of the outer horizontal limiting mesh cloth 21, and the inner side of the upper vertical limiting mesh cloth 23 is connected to the upper end of the inner horizontal limiting mesh cloth 22. The upper vertical limiting mesh cloth 23 forms the water inlet side;

[0052] The lower vertical limiting mesh cloth 24 is wrapped around the bottom of the filter element main body 1, the lower ends of the outer horizontal limiting mesh cloth 21 and the inner horizontal limiting mesh cloth 22. The outer side of the lower vertical limiting mesh cloth 24 is connected to the lower end of the outer horizontal limiting mesh cloth 21, and the inner side of the lower vertical limiting mesh cloth 24 is connected to the lower end of the inner horizontal limiting mesh cloth 22. The lower vertical limiting mesh cloth 24 forms the water outlet side. In this way, during the preparation of the humidifying filter element, the outer horizontal limiting mesh cloth 21 can be attached to the outer side wall of the filter element main body 1, then the inner horizontal limiting mesh cloth 22 can be attached to the inner side wall of the filter element main body 1, then the upper vertical limiting mesh cloth 23 can be attached to the top of the filter element main body 1, the upper ends of the outer horizontal limiting mesh cloth 21 and the inner horizontal limiting mesh cloth 22. Then, the outer side of the upper vertical limiting mesh cloth 23 is connected to the upper end of the outer horizontal limiting mesh cloth 21, and the inner side of the upper vertical limiting mesh cloth 23 is connected to the upper end of the inner horizontal limiting mesh cloth 22. Then, the lower vertical limiting mesh cloth 24 is attached to the bottom of the filter element main body 1, the lower ends of the outer horizontal limiting mesh cloth 21 and the inner horizontal limiting mesh cloth 22. Finally, the outer side of the lower vertical limiting mesh cloth 24 is connected to the lower end of the outer horizontal limiting mesh cloth 21, and the inner side of the lower vertical limiting mesh cloth 24 is connected to the lower end of the inner horizontal limiting mesh cloth 22, and the preparation of the humidifying filter element can be completed. The limiting mesh cloth 2 can be quickly installed on the filter element main body 1, and the installation efficiency is higher. Among them, the outer horizontal limiting mesh cloth 21 and the inner horizontal limiting mesh cloth 22 jointly limit the movement of the filter element main body 1 in the horizontal direction, ensuring the thickness and shape stability of the filter element main body 1, being beneficial to assembly and maintaining the shape stability during the water washing process. The upper vertical limiting mesh cloth 23 and the lower vertical limiting mesh cloth 24 jointly limit the movement of the filter element main body 1 in the vertical direction, ensuring the relative vertical position stability of the filter element main body 1, being beneficial to assembly and maintaining the shape stability during the water washing process.

[0053] See Figure 4 , in an embodiment, when the number of the filter element main bodies 1 is at least two, at least two filter element main bodies 1 are arranged in sequence along the radial direction of the humidifying filter element;

[0054] The outer side walls of the respective filter element main bodies 1 are all wrapped by a piece of outer horizontal limiting mesh cloth 21, and the inner side walls of the respective filter element main bodies 1 are all wrapped by a piece of inner horizontal limiting mesh cloth 22;

[0055] The upper vertical limiting mesh cloth 23 is wrapped around the tops of at least two filter element main bodies 1, the upper ends of the outermost outer horizontal limiting mesh cloth 21 and the upper ends of the innermost inner horizontal limiting mesh cloth 22;

[0056] The lower vertical limiting mesh cloth 24 covers the bottoms of at least two filter element bodies 1, the lower ends of the outermost outer horizontal limiting mesh cloth 21, and the lower ends of the innermost inner horizontal limiting mesh cloth 22. Since the outer side walls of the respective filter element bodies 1 are covered by a piece of outer horizontal limiting mesh cloth 21 and the inner side walls of the respective filter element bodies 1 are covered by a piece of inner horizontal limiting mesh cloth 22, each filter element body 1 is horizontally limited by a piece of outer horizontal limiting mesh cloth 21 and a piece of inner horizontal limiting mesh cloth 22 together, enabling each filter element body 1 to stably maintain its original shape after multiple washings, with higher structural reliability. At the same time, since the tops of the respective filter element bodies 1 are covered by the same upper vertical limiting mesh cloth 23 and the bottoms of the respective filter element bodies 1 are covered by the same lower vertical limiting mesh cloth 24, while saving the usage quantity of the upper vertical limiting mesh cloth 23 and the lower vertical limiting mesh cloth 24, it can also simplify the connection between the limiting mesh cloth 2 and the filter element body 1, making it easier to quickly install the limiting mesh cloth 2 on the filter element body 1 with higher installation efficiency. Additionally, since the upper vertical limiting mesh cloth 23 covers the tops of at least two filter element bodies 1, the upper ends of the outermost outer horizontal limiting mesh cloth 21, the upper ends of the innermost inner horizontal limiting mesh cloth 22, and the lower vertical limiting mesh cloth 24 covers the bottoms of at least two filter element bodies 1, the lower ends of the outermost outer horizontal limiting mesh cloth 21, and the lower ends of the innermost inner horizontal limiting mesh cloth 22, the upper ends of at least two filter element bodies 1 are connected integrally and the lower ends of at least two filter element bodies 1 are connected integrally, without being scattered, making it more convenient for the installation of the humidifying filter element.

[0057] See Figures 1-4 , in an embodiment, the humidifying filter element further includes:

[0058] The upper connecting line 3 is arranged around the vertical center line of the filter element body 1. The upper connecting line 3 passes through the mesh holes outside the upper vertical limiting mesh cloth 23, the mesh holes at the upper ends of the outer horizontal limiting mesh cloth 21, the filter element body 1, the mesh holes at the upper ends of the inner horizontal limiting mesh cloth 22, and the mesh holes inside the upper vertical limiting mesh cloth 23 to connect the outside of the upper vertical limiting mesh cloth 23, the upper ends of the outer horizontal limiting mesh cloth 21, the filter element body 1, the inside of the upper vertical limiting mesh cloth 23, and the upper ends of the inner horizontal limiting mesh cloth 22 together. The setting of the upper connecting line 3 can reliably connect the outside of the upper vertical limiting mesh cloth 23, the upper ends of the outer horizontal limiting mesh cloth 21, the filter element body 1, the inner horizontal limiting mesh cloth 22, and the inside of the upper vertical limiting mesh cloth 23 together, which is beneficial to strengthening the structural reliability of the filter element body 1 and making the filter element body 1 not easily deformed after multiple washings.

[0059] See Figures 1-2 , in an embodiment, the humidifying filter element further includes:

[0060] The lower connecting line 4 is arranged around the vertical center line of the filter element main body 1. The lower connecting line 4 passes through the mesh holes on the outer side of the lower vertical limiting mesh cloth 24, the mesh holes at the lower end of the outer horizontal limiting mesh cloth 21, the filter element main body 1, the mesh holes at the lower end of the inner horizontal limiting mesh cloth 22 and the mesh holes on the inner side of the lower vertical limiting mesh cloth 24, so as to connect the outer side of the lower vertical limiting mesh cloth 24, the lower end of the outer horizontal limiting mesh cloth 21, the filter element main body 1, the lower end of the inner horizontal limiting mesh cloth 22 and the inner side of the lower vertical limiting mesh cloth 24 together. Similarly, the arrangement of the lower connecting line 4 can reliably connect the outer side of the lower vertical limiting mesh cloth 24, the lower end of the outer horizontal limiting mesh cloth 21, the filter element main body 1, the inner side of the lower vertical limiting mesh cloth 24 and the lower end of the inner horizontal limiting mesh cloth 22 together, which is beneficial to strengthening the structural reliability of the filter element main body 1 and making the filter element main body 1 less likely to deform.

[0061] In one embodiment, both the upper connecting line 3 and the lower connecting line 4 are telescopic knots. The upper connecting line 3 with a telescopic knot structure can adjust the tightness of the upper end of the humidifying filter element. Among them, when the upper connecting line 3 is tightened, the upper end of the humidifying filter element can be reliably fixed to the plastic structural part. When the upper connecting line 3 is loosened, it is convenient to remove the upper end of the humidifying filter element from the plastic structural part. Similarly, the lower connecting line 4 with a telescopic knot structure can adjust the tightness of the lower end of the humidifying filter element. Among them, when the lower connecting line 4 is tightened, the lower end of the humidifying filter element can be reliably fixed to the plastic structural part. When the lower connecting line 4 is loosened, it is convenient to remove the lower end of the humidifying filter element from the plastic structural part, so that the disassembly and assembly operation between the humidifying filter element and the plastic structural part is simpler and more convenient. In addition, the upper connecting line 3 and the lower connecting line 4 with a telescopic knot structure have higher structural stability and are not prone to thread-off phenomena, making the connection between the outer side of the upper vertical limiting mesh cloth 23, the upper end of the outer horizontal limiting mesh cloth 21, the filter element main body 1, the inner horizontal limiting mesh cloth 22 and the inner side of the upper vertical limiting mesh cloth 23 more stable and reliable, and making the connection between the outer side of the lower vertical limiting mesh cloth 24, the lower end of the outer horizontal limiting mesh cloth 21, the filter element main body 1, the inner side of the lower vertical limiting mesh cloth 24 and the lower end of the inner horizontal limiting mesh cloth 22 more stable and reliable.

[0062] In other embodiments, both the upper connecting line 3 and the lower connecting line 4 can be of ordinary sewing structures.

[0063] In one embodiment, the water flow channel extends vertically along the filter element main body 1, and the air flow channel extends horizontally along the filter element main body 1, that is, the air flow channel is perpendicular to the water flow channel. To a certain extent, it can reduce the resistance between them, is more conducive to water vapor evaporation and humidification, and can further improve the humidification efficiency.

[0064] In other embodiments, the air flow channel can also be inclined to the water flow channel.
