[0030] The utility model discloses a humidifying filter screen, because multiple filter screen units 1 are all set outwards to the vertical center line of humidifying filter screen, the cross section of each filter screen unit 1 is arc, and the vertical center line of each filter screen unit 1 does not coincide with the vertical center line of humidifying filter screen, make the cross section of humidifying filter screen present the non - circular structure with multiple outwards convex arcs, can significantly increase the surface area of humidifying filter screen, thereby expand the air inlet area, simultaneously, need not increase the height of humidifying filter screen, also need not too much increase the diameter of humidifying filter screen, therefore will not too much increase the overall volume of humidifying filter screen, the cross section of humidifying filter screen is polygon by the same reason, can significantly increase the surface area of humidifying filter screen, thereby expand the air inlet area, simultaneously, will not too much increase the overall volume of humidifying filter screen, in addition, the setting of support part 2 can play the role of the form of fixed filter screen unit 1, ensure that humidifying unit can stably maintain in the state of cross section arc or rectangle, also namely enhanced the structural stability and strength of humidifying filter screen, make filter screen unit 1 not be deformed in the humidification process due to the effect of airflow or moisture, thereby guarantee the stability and durability of humidification effect, the humidifying filter screen of the above-mentioned, through the structural optimization of filter screen unit 1 while increasing the form of fixed filter screen unit 1 of support part 2, significantly increase the effective air inlet area of filter screen, improve the humidification performance, realize the miniaturization and aestheticization of humidifying filter screen simultaneously, do not occupy too much space, more conducive to the miniaturization design of humidifier.

[0031] In an embodiment, two adjacent filter screen units 1 are stitched to form a support part 2 between them, that is, two adjacent filter screen units 1 are connected together by stitching, and after stitching the two adjacent sides of the two adjacent filter screen units 1, a support part 2 is formed. This structure can effectively fix the relative position of the filter screen units 1 and prevent the filter screen units 1 from deforming or collapsing due to the impact of airflow or moisture during use. In addition, the support part 2 formed by stitching provides additional structural support for the filter screen units 1, ensuring that the filter screen units 1 maintain a stable shape during humidification, thereby maintaining high humidification performance.

[0032] Of course, in other embodiments, two adjacent filter screen units 1 can also be connected by bonding or hot pressing to form a support part 2.

[0033] In an embodiment, the two adjacent edges of the two adjacent filter screen units 1 are stacked and stitched, and the support part 2 is formed into a double-layer structure. This design not only increases the thickness and strength of the humidifying filter screen locally, but also firmly fixes the two filter screen units 1 together through the stitched connection, preventing the filter screen units 1 from deforming or collapsing due to the impact of airflow or moisture during use. In addition, the stacked and stitched connection significantly enhances the structural strength and stability of the filter screen units 1, ensuring that the filter screen units 1 maintain a stable shape during humidification, thereby maintaining high-efficiency humidification performance.

[0034] In an embodiment, the two adjacent filter screen units 1 are stitched together by a waterproof thread. The stitched connection of the two adjacent filter screen units 1 by the waterproof thread not only firmly fixes the filter screen units 1, but also effectively prevents moisture from penetrating into the inside of the thread, avoiding thread aging or breakage caused by moisture erosion. Therefore, the connection strength between the filter screen units 1 is enhanced by the waterproof thread stitching, ensuring that the filter screen units 1 maintain a stable shape and structure during long-term use, thereby prolonging the service life of the humidifying filter screen.

[0035] Of course, in other embodiments, the two adjacent filter screen units 1 can also be stitched together by other ordinary stitching threads.

[0036] In an embodiment, the support part 2 extends from the upper end to the lower end of the filter screen unit 1, so that the support part 2 penetrates the entire height of the filter screen unit 1, providing full-height support for the filter screen unit 1. This design ensures that the filter screen unit 1 maintains a stable shape throughout the entire height range, avoiding local deformation due to the impact of airflow or moisture. Therefore, the full-height support part 2 significantly enhances the overall structural stability of the filter screen unit 1, ensuring that the filter screen unit 1 always maintains the designed shape during humidification, thereby maintaining high-efficiency humidification performance.

[0037] In an embodiment, the filter screen unit 1 comprises at least two filter screen units stacked in sequence along the radial direction of the humidifying filter screen, increasing the thickness of the filter screen unit 1, so that the filter screen unit 1 realizes a larger surface area and water absorption capacity in a limited space. This design improves the humidifying performance without significantly increasing the height and diameter of the filter screen. In addition, the stacking design of the multiple layers of filter screen units can form a multi-stage filtering effect. The dust and impurities in the air will be intercepted layer by layer when passing through the multiple layers of filter screen units, reducing the impact on the humidifying performance. In addition, the design of the multiple layers of filter screen units improves the dust holding capacity of the humidifying filter screen, reducing the risk of clogging of the filter screen unit 1 and ensuring long-term efficient operation of the humidifier. In addition, by stacking at least two filter screen units, the overall structural strength of the filter screen unit 1 is enhanced, and the multiple layers of filter screen units support each other, better resisting the impact of airflow and moisture, reducing the risk of deformation and damage, improving the durability of the humidifying filter screen, prolonging the service life of the humidifying filter screen, and reducing the performance degradation caused by deformation of the filter screen unit 1.

[0038] Of course, in other embodiments, the filter screen unit 1 can be provided as a single-layer structure.

[0039] In an embodiment, the humidifying filter screen further comprises:

[0040] a first edge wrapping body 3 wrapping the inner and outer side walls of the upper ends of the multiple filter screen units 1 and the multiple support parts 2 to form an upper support structure;

[0041] a second edge wrapping body 4 wrapping the inner and outer side walls of the lower ends of the multiple filter screen units 1 and the multiple support parts 2 to form a lower support structure. The provision of the first edge wrapping body 3 and the second edge wrapping body 4 reinforces the upper and lower ends of the filter screen unit 1, preventing the filter screen unit 1 and the support part 2 from deforming or separating during use, thereby ensuring the structural stability and durability of the humidifying filter screen. In addition, the first edge wrapping body 3 and the second edge wrapping body 4 wrap the inner and outer side walls of the upper and lower ends of the filter screen unit 1 and the support part 2, effectively protecting the edges of the filter screen unit 1 and the support part 2 from wear due to friction or moisture erosion. In addition, the design of the first edge wrapping body 3 and the second edge wrapping body 4 allows the upper and lower ends of the filter screen unit 1 and the support part 2 to be neatly wrapped, forming a whole structure that is easy to install and disassemble. In addition, the first edge wrapping body 3 and the second edge wrapping body 4 wrap the inner and outer side walls of the upper and lower ends of the filter screen unit 1 and the support part 2, making the upper and lower ends of the filter screen more neat and aesthetically pleasing, improving the appearance and texture of the humidifying filter screen. In addition, the first edge wrapping body 3 and the second edge wrapping body 4 wrap the inner and outer side walls of the upper and lower ends of the filter screen unit 1 and the support part 2, allowing water to pass evenly through the filter screen unit 1 and avoiding uneven water distribution.

[0042] In an embodiment, the filter screen unit 1, the first edge wrapping body 3 and the second edge wrapping body 4 are all structures made of mesh cloth material. The high air permeability of the mesh cloth material ensures that air can smoothly pass through the filter screen unit 1, the first edge wrapping body 3 and the second edge wrapping body 4, ensuring efficient operation of the humidifier. In addition, the water absorption of the mesh cloth material enables the filter screen unit 1, the first edge wrapping body 3 and the second edge wrapping body 4 to uniformly absorb and release moisture, achieving fog-free humidification. In addition, the materials of the entire humidification filter screen are consistent, avoiding performance fluctuations caused by material differences and ensuring the stability of the humidification effect. In addition, the mesh cloth material has good water resistance and corrosion resistance, and the design of the first edge wrapping body 3 and the second edge wrapping body 4 further protects the edges of the filter screen unit 1, prolonging the service life of the humidification filter screen. In addition, the filter screen unit 1, the first edge wrapping body 3 and the second edge wrapping body 4 all use mesh cloth material, which can be connected by sewing, without the need for additional bonding or hot pressing process, simplifying the manufacturing process.

[0043] In an embodiment, the filter screen unit 1 is a structure made of 3D mesh cloth material. The filter screen unit 1 made of 3D mesh cloth material has a more complex three-dimensional structure, can provide a larger surface area and more pores, and thus significantly improves air permeability and water absorption. In addition, the structure of the 3D mesh cloth enables moisture to be more evenly distributed on the surface of the filter screen unit 1, and air can pass through the filter screen unit 1 more smoothly, thereby improving humidification efficiency and uniformity. In addition, the 3D mesh cloth material has stronger structural strength and three-dimensional support, which can better maintain the shape of the filter screen unit 1, avoiding collapse or deformation caused by soft material, thereby ensuring the stability of the humidification performance. In addition, the structure of the 3D mesh cloth enables the filter screen unit 1 to achieve a larger effective area in a limited space, thereby optimizing space utilization and meeting the user's demand for product miniaturization and light weight.
