Its main function is to evenly distribute the water through capillary action and fully contact the air, so as to achieve the humidification effect. The wet curtain is generally cut from a substrate with a certain thickness and then bent and rolled into a cylindrical structure. Since the water distributor at the top of the wet curtain is not equipped with a filter, impurities are easily accumulated at the end of the wet curtain, and the impurities will enter the inside of the wet curtain, which will reduce the humidification effect after long-term use.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] like Figures 1 to 3As shown, in the first aspect, an embodiment of the present application provides a wet curtain 100, including a edging 10 and a cylinder body, the cylinder body is formed by connecting two short sides of two first long sides 21 of a rectangular substrate 20 after being folded in half, and an exposed cutting plane 30 is formed at the top of the cylinder body after the substrate 20 is folded in half; the edging 10 surrounds and covers the cutting plane 30 of the cylinder body, and the edging 10 has two opposite second long sides 11, and the two second long sides 11 extend toward the inner side and the outer side of the cylinder body respectively to form a skirt 12, and the skirt 12 at least partially overlaps with the two first long sides 21 and is sewn and fixed.

[0023] In the actual production process, Figure 3 As shown, the rectangular substrate 20 can be folded along the axis P so that its two first long sides 21 overlap, and then the two short sides of the folded substrate 20 are connected. The connected parts can then be directly sewn or indirectly sewn and fixed through fabric to form a stable cylinder.

[0024] Among them, during the folding process of the two first long sides 21 of the substrate 20, the thickness surfaces 23, that is, the cutting surfaces of the substrate 20, are attached to each other and flush to form a cutting plane 30 of the cylinder, so that the cutting plane 30 is a solid plane formed by the actual thickness of the substrate 20. This allows the entire wet curtain 100 to naturally maintain a stable cylindrical shape after the short sides 22 are sewn and fixed, without the need for any additional support structure.

[0025] On this basis, the edging 10 surrounds and covers the cutting plane 30, and its two second long sides 11 extend to the inner and outer sides of the cylinder respectively to form a skirt 12. The skirt 12 forms an overlapping area with the two first long sides 21 of the substrate 20 after being folded in half, and are firmly connected by sewing. This structural design not only ensures that the wet curtain 100 has excellent self-supporting performance, but also enables the cutting plane 30 to have sufficient strength and flatness, and can achieve precise and stable cooperation with the water distribution structure of the humidifier.

[0026] In addition, since the thickness surface 23 is the cutting surface of the substrate 20, burrs or small gaps are prone to occur. These burrs or gaps are easy to harbor dirt and breed bacteria, and may also become channels for impurities in the water to enter the interior of the substrate 20. In this embodiment, the skirt 12 of the edging 10 overlaps and is sewn with the substrate 20, which effectively closes these burrs and gaps to form a barrier to prevent larger impurities such as dust and hair mixed in the humidification water from entering the interior of the substrate 20 from the top of the wet curtain 100, thereby avoiding the accumulation of impurities and reducing the frequency and difficulty of cleaning.

[0027] In some embodiments, the edge 10 is a stretch mesh. The mesh structure of the stretch mesh makes it have good air permeability and flexibility. At the same time, its inherent tensile strength can provide effective protection for the cutting plane 30, especially when the wet curtain 100 needs to be taken out for cleaning after being used for a period of time; for example, the user may rub or squeeze the wet curtain 100 when cleaning, and the stretch mesh structure can effectively disperse these external forces, prevent the cutting plane 30 from being deformed or damaged, thereby extending the service life of the wet curtain 100.

[0028] In some embodiments, Figure 2 As shown, the substrate 20 includes a core layer 20a and a surface layer 20b arranged on both sides of the core layer 20a, and the core layer 20a and the surface layer 20a are both porous structures. In specific implementation, the core layer 20a and the surface layer 20b of different materials can be selected according to different needs; for example, a material with stronger water absorption can be selected as the core layer 20a, and a material with higher strength and more wear resistance can be selected as the surface layer 20b. In addition, the porous structure of the core layer 20a and the surface layer 20b can increase the contact area between the wet curtain and the air, thereby increasing the evaporation rate of water, and further improving the humidification efficiency.

[0029] In another example, the core layer 20a is made of composite fibers, and the surface layer 20b is a stretched mesh. In specific implementation, the water-absorbing fibers can be composite fibers of absorbent materials or non-absorbent materials, such as highly absorbent resin fibers or other suitable materials, to quickly absorb and evenly distribute the humidification water; and the surface layer 20b is a stretched mesh, which can provide support and protection for the core layer 20a, especially to prevent the core layer 20a from excessively expanding or deforming in a wet state when the absorbent material is used.

[0030] In some embodiments, the stretch net is made of water-absorbing material. This design allows the edge 10 and the surface layer 20b to not only prevent the core layer 20a from excessively swelling or deforming due to water absorption, but also to cooperate with the core layer 20a to absorb water and humidify. In particular, the skirt 12 of the edge 10, due to the stretch net made of water-absorbing material, can quickly introduce the humidification water dispersed at the top into the substrate 20, thereby improving the humidification efficiency and preventing water accumulation. In addition, the stretch net made of water-absorbing material can maintain good toughness and durability even in repeated soaking and drying cycles, thereby extending the service life of the wet curtain 100.

[0031] It should be noted that the aperture of the stretch mesh used in the edge 10 and the surface layer 20b can be selected according to actual needs. Usually, the aperture of the stretch mesh of the edge 10 is relatively small, such as about 1mm, and is mainly used to filter out larger impurities in the water, such as hair, dust, etc., to prevent them from clogging the wet curtain 100 or entering the inside of the substrate; while the aperture of the stretch mesh of the surface layer 20b can be relatively large, such as 3-10mm or even larger, to facilitate air circulation and full contact with the core layer 20a, thereby improving the humidification efficiency. Selecting the appropriate aperture can balance the filtering effect and air permeability to achieve the best humidification performance.

[0032] In this embodiment, if Figure 3 As shown, the two short sides 22 of the two first long sides 21 of the substrate 20 are at least partially overlapped and sewn to fix, and the seams of the two short sides 22 are located on the inner side of the cylinder. In this way, the overlapping seams can sew the two layers of the folded substrate 20 together to better maintain the shape of the cylinder from collapse and deformation, especially when the wet curtain is saturated with water; at the same time, the seams are located on the inner side of the cylinder, so that there is no exposed seam or cut surface of the substrate 20 on the outer side of the wet curtain, thereby improving the visual effect of the product.

[0033] In this embodiment, if Figure 1 As shown, a reinforcement line 40 is sewn near the bottom of the cylinder to sew the inner layer and the outer layer of the cylinder near the bottom. In specific implementation, the material of the reinforcement line 40 can be selected from nylon line, polyester line or other sewing lines with sufficient strength and water resistance. During the use of the wet curtain 100, especially when it is saturated with water, the bottom edge is easy to spread outward due to the action of gravity and the deformation of the substrate 20 material, causing the wet curtain 100 to deform, affecting its humidification efficiency and service life. The addition of the reinforcement line 40 can effectively limit the expansion of the bottom of the wet curtain 100, so that it maintains a compact cylindrical shape, and prevent the bottom from being fluffy and spreading even when it is saturated with water.

[0034] Furthermore, a plurality of reinforcing lines 40 are provided, and the plurality of reinforcing lines 40 are spaced apart along the axial direction of the cylinder. For example, 2-5 or even more reinforcing lines 40 may be sewn, and the distance between them may be adjusted according to the height of the wet curtain 100, that is, the provision of a plurality of reinforcing lines 40 may provide more uniform and comprehensive support, effectively preventing the wet curtain 100 from deforming, bending or collapsing during stress or long-term use, further improving the stability and service life of the wet curtain 100, and ensuring that it can maintain the best humidification performance for a long time.

[0035] In the second aspect, the embodiment of the present application provides a humidifier, including a humidifier body (not shown), a frame 50 disposed in the humidifier body, and a wet curtain sleeved on the frame 50, the wet curtain being the wet curtain 100 of any embodiment of the first aspect, the top of the frame 50 being detachably mounted with a water distribution tray 60, the bottom surface of the water distribution tray 60 being provided with an annular positioning groove 61 for accommodating the cutting plane 30. Specifically, the frame 50 and the water distribution tray 60 can be mounted and fixed together in a buckle-joined manner, the top of the frame 50 can be provided with an undercut, and the corresponding position of the water distribution tray 60 can be provided with a matching slot, and the detachable assembly between the frame 50 and the water distribution tray 60 is achieved by the cooperation between the undercut and the slot.

[0036] In specific implementation, the material of the frame 50 can be plastic, metal or other suitable materials, and its function is to support the wet curtain and keep it in a cylindrical shape, and the design of the water distribution tray 60 can be adjusted according to actual needs, for example, a plurality of water distribution holes can be set on its bottom surface to evenly distribute water to the cutting plane 30 of the wet curtain 100. Among them, the wet curtain is the wet curtain 100 of any of the previous embodiments, and the shape and size of the annular positioning groove 61 match the cutting plane 30 of the wet curtain 100, and the wet curtain 100 can be accurately positioned at the center of the water distribution tray 60 to ensure a good fit between the wet curtain 100 and the water distribution tray 60, which avoids the wet curtain 100 from being offset or tilted during use, thereby affecting the humidification effect. At the same time, the annular positioning groove 61 can guide the water flow on the water distribution tray 60 to flow evenly to the cutting plane 30 of the wet curtain 100, promote the uniform distribution of water, thereby improving the humidification efficiency, and also help prevent water from leaking from the gap between the wet curtain 100 and the water distribution tray 60.

[0037] The wet curtain and humidifier provided in the present embodiment form a cutting plane by folding a rectangular substrate along the thickness surfaces of the two long sides, so that the wet curtain can maintain a stable cylindrical shape without the need for external support, and the cutting plane after folding has high structural strength, is not easy to deform, and can be firmly matched with the water distribution tray; at the same time, the edging surrounds and covers the cutting plane of the cylinder, and is fixedly connected by overlapping and sewing the inner and outer skirts with the substrate, which not only improves the overall strength of the top structure, but also effectively prevents impurities in the humidification water from entering the interior of the substrate through the sealing effect of the edging, thereby reducing the difficulty of cleaning and maintenance of the wet curtain and extending its service life.
