Detailed Embodiments

[0020] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0021] Such as Figures 1 to 3As shown, in a first aspect, an embodiment of the present application provides a wet curtain 100, which includes a cylinder body formed by folding the two long sides A1 of a rectangular base material 10 towards each other and sewing them, and then connecting the two short sides B1 end to end. The sewing line for sewing the two long sides A1 of the base material 10 is located at the middle position or a position close to the middle in the axial direction of the cylinder body. In this embodiment, for the rectangular base material 10, materials with good water absorption can be selected, such as non-woven fabric, plant fiber, synthetic fiber, etc., or materials such as composite fibers that do not absorb water can also be selected.

[0022] During the actual manufacturing process, as Figure 3 shown, the long sides A1 of the rectangular base material 10 can be folded inward along the axis P1 and the axis P2 respectively, and then the two long sides A1 are sewn and fixed on the same side of the base material 10. Subsequently, the two short sides B1 of the base material 10 are curled and connected end to end, and the connected part is directly sewn or indirectly sewn and fixed through cloth, thereby forming a stable cylinder body, where the sewing line for sewing the two long sides A1 of the base material 10 is located at the middle position or a position close to the middle in the axial direction of the cylinder body.

[0023] In this way, the sewing line for sewing the two long sides A1 after folding is located at the middle position or a position close to the middle in the axial direction of the cylinder body, which can make the cut surface of the base material corresponding to the part of the long side A1 away from the top and bottom parts of the cylinder body, that is, the top and bottom edges of the cylinder body are formed by the self-folding of the base material 10. The top and bottom parts of the wet curtain 100 are continuous and flat, without the exposure of the cut section of the base material 10. Furthermore, there is no need to additionally set up structures such as edging to cover the exposed top of the cylinder body, avoiding the accumulation of impurities at the end of the wet curtain 100 or the possibility of impurities entering the inside of the wet curtain 100 during long-term use.

[0024] In this embodiment, the sewing line for sewing the two long sides A1 of the base material 10 is located inside the cylinder body. In this way, placing the sewing line for sewing the two long sides A1 inside the cylinder body can make the outside of the wet curtain 100 have no exposed sewing line or cut surface of the base material 10, thereby improving the visual effect of the product. Of course, in addition to curling the two short sides B1 of the base material 10 inward, the short sides B1 can also be curled outward and connected end to end, so that the sewing line for sewing the two long sides A1 of the base material 10 is located outside the cylinder body. Which curling method to choose depends on the specific application scenario and design requirements. For example, if the wet curtain 100 needs to be closely attached to other components, the inward or outward curling method can be selected according to the position of the attachment surface to ensure the best matching effect.

[0025] In some embodiments, as Figure 1 、 Figure 2As shown, when the two long sides A1 of the base material 10 are folded towards each other, a first folded edge 11 and a second folded edge 12 are formed. The first folded edge 11 and the second folded edge 12 at least partially overlap to form an overlapping area 20. The first folded edge 11 and the second folded edge 12 are sewn and fixed in the overlapping area 20. The overlapping area 20 extends along the length direction of the base material 10 and is of the same length as the base material 10.

[0026] In this way, since the overlapping area 20 is composed of the first folded edge 11 and the second folded edge 12, its thickness is greater than that of the base material 10, making the overlapping area 20 like an internal reinforcing ring extending along the circumferential direction of the wet curtain 100, which can effectively enhance the overall strength and anti-deformation ability of the wet curtain 100, and effectively prevent the wet curtain 100 from deforming due to stress or immersion during long-term use. In addition, since the overlapping area 20 is located inside the cylinder, it is not easy for users to directly pull the sewing thread when cleaning and kneading the wet curtain 100, reducing the risk of the sewing thread breaking or the wet curtain 100 deforming, thereby extending the service life of the wet curtain 100.

[0027] In some embodiments, at least part of the two short sides B1 of the base material 10 overlap and are sewn and fixed, and the sewing thread for sewing the two short sides B1 is located inside the cylinder. In this way, the overlapping sewing can sew the two overlapping layers of the base material 10 together to better maintain the shape of the cylinder from collapsing and deforming, especially when the wet curtain is saturated with water; at the same time, the sewing thread is located inside the cylinder, and there are no exposed sewing threads or cut surfaces of the base material 10 on the outside of the wet curtain, further improving the visual effect of the product.

[0028] In some embodiments, the part of the base material 10 corresponding to the overlapping area 20 is sewn and fixed to the first folded edge 11 and the second folded edge 12. Sewing and fixing the base material 10, the first folded edge 11 and the second folded edge 12 in the overlapping area 20 forms a firm three-layer structure. Compared with the double-layer structure that only sews the first folded edge 11 and the second folded edge 12, it significantly improves the anti-tensile ability and overall stability of the wet curtain 100, and can also prevent the first folded edge 11 and the second folded edge 12 from spreading out due to the lack of restraint between the folded edges and the base material 10, ensuring that the wet curtain 100 can better maintain the preset cylindrical shape even in a wet state and prevent deformation or tearing.

[0029] In some embodiments, such as Figure 1 、 Figure 2 As shown, reinforcing lines 30 are sewn at positions near the top and / or bottom of the cylinder to sew the inner layer and the outer layer of the cylinder.

[0030] In specific implementation, the material of the reinforcing thread 30 can be selected from nylon thread, polyester thread or other sewing threads with sufficient strength and water resistance. During the use of the wet curtain 100, especially in the state of being saturated with water absorption, it is easy to spread outwards due to the gravity and the deformation of the substrate 10 material, resulting in the deformation of the wet curtain 100 and affecting its humidification efficiency and service life. The addition of the reinforcing thread 30 can effectively limit the expansion of the folding positions of the first folded edge 11 and the second folded edge 12, keeping it in a compact cylindrical shape and preventing it from spreading out even when saturated with water absorption.

[0031] In this embodiment, a plurality of reinforcing threads 30 are provided, and the plurality of reinforcing threads 30 are spaced along the axial direction of the cylinder. For example, 2 - 5 circles or even more circles of reinforcing threads 30 can be sewn, and the distance between them can be adjusted according to the height of the wet curtain 100. That is, the arrangement of the plurality of reinforcing threads 30 can provide more uniform and comprehensive support, effectively preventing the wet curtain 100 from deforming, bending or collapsing during force application 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.

[0032] In some embodiments, as Figure 2 shown, the substrate 10 includes a core layer 10a and surface layers 10b provided on both sides of the core layer 10a, and both the core layer 10a and the surface layers 10b are porous structures. In specific implementation, different materials of the core layer 10a and the surface layers 10b can be selected according to different requirements. For example, a material with stronger water absorption can be selected as the core layer 10a, and a material with higher strength and more wear resistance can be selected as the surface layers 10b. In addition, the porous structures of the core layer 10a and the surface layers 10b 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.

[0033] In this embodiment, the core layer is made of composite fibers. In specific implementation, the water-absorbing fibers can be composite fibers of water-absorbing materials or non-water-absorbing materials, such as high water-absorbing resin fibers or other suitable materials, to quickly absorb and evenly distribute the humidifying water.

[0034] In this embodiment, the surface layer 10b is a stretch mesh. With this structure, on the one hand, it can provide support and protection for the core layer 10a to prevent it from expanding or deforming excessively in the wet state; on the other hand, the mesh structure of the stretch mesh can increase the contact area between the air and the wet core layer 10a, thereby improving the humidification efficiency.

[0035] Furthermore, the stretching net is made of a water-absorbing material. This design enables the surface layer 10b, when using the water-absorbing material, not only to prevent the core layer 10a from excessive water absorption and swelling or deformation, but also to cooperate with the core layer 10a for water absorption and humidification. In addition, the stretching net made of the water-absorbing material can maintain good toughness and durability even in the cycle of repeated wetting and drying, thereby extending the service life of the wet curtain 100.

[0036] In a second aspect, as Figure 4 , Figure 5 shown, an embodiment of the present application provides a humidifier, which includes a humidifier body (not shown in the figure), a skeleton 40 disposed inside the humidifier body, and a wet curtain sleeved on the skeleton 40. The wet curtain is the wet curtain 100 of any one of the embodiments in the first aspect. A water distribution tray 50 is detachably installed at the top end of the skeleton 40, and an annular positioning groove 51 for accommodating the top end of the wet curtain 100 is provided on the bottom surface of the water distribution tray 50.

[0037] Specifically, the material of the skeleton 40 can be selected from plastics, metals or other suitable materials, and its function is to support the wet curtain and keep it in a cylindrical shape. The design of the water distribution tray 50 can be adjusted according to actual needs. For example, a plurality of water distribution holes can be provided on its bottom surface to evenly distribute water onto the top plane of the wet curtain 100. Among them, the wet curtain is the wet curtain 100 of any one of the previous embodiments, and the shape and size of the annular positioning groove 51 match those of the wet curtain 100, which can accurately position the wet curtain 100 at the center position of the water distribution tray 50, ensuring a good fit between the wet curtain 100 and the water distribution tray 50. This avoids the wet curtain 100 from shifting or tilting during use, thereby affecting the humidification effect. At the same time, the annular positioning groove 51 can guide the water flow on the water distribution tray 50 to evenly flow to the top end of the wet curtain 100, promoting the uniform distribution of water, thereby improving the humidification efficiency, and also helping to prevent water from leaking out from the gap between the wet curtain 100 and the water distribution tray 50. Specifically, the skeleton 40 and the water distribution tray 50 can be installed and fixed together by a snap connection method. An inverted buckle can be provided at the top end of the skeleton 40, and a matching card slot can be provided at the corresponding position of the water distribution tray 50, and the detachable assembly between the skeleton 40 and the water distribution tray 50 is realized through the cooperation of the inverted buckle and the card slot.

[0038] For the wet curtain and the humidifier provided in this embodiment, by folding the two long sides of the rectangular substrate towards each other and overlapping and fixing them to form a cylinder, there is no need to additionally provide a similar structure such as a hem to cover the exposed ends of the cylinder, avoiding the possibility of accumulating impurities at the ends of the wet curtain or impurities entering the inside of the wet curtain during long-term use. In addition, the formed overlapping area enhances the overall strength of the wet curtain, effectively preventing the wet curtain from deforming during long-term use and reducing the need for the wet curtain for additional support structures.
