[0024] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0025] This invention provides a wettable core material that can be used in air conditioning equipment. (Refer to the reference...) Figure 1 and Figure 2The core material 10 may include a first core layer 110 and a second core layer 120. Air can circulate through the first core layer 110 and the second core layer 120. The first core layer 110 may have multiple first holes, and the second core layer 120 may have multiple second holes. The opening areas of the first holes 110 and the second holes 120 are different. The first core layer 110 can be formed into a cylindrical shape. The second core layer 120 is disposed on one side of the first core layer 110. In use, a water sprayer sprays water onto the first core layer 110 and the second core layer 120, keeping the core material 10 moist. The water on the first core layer 110 and the second core layer 120 converts into water vapor, which flows into the external space. The difference in the opening areas of the first and second holes affects, to some extent, the evaporation rate of the water vapor on the first core layer 110 and the second core layer 120. When the first core layer 110 and the second core layer 120 are immersed in a liquid, the water retention per unit weight of the first core layer 110 differs from that of the second core layer 120. Water retention per unit weight refers to the amount of water that a unit mass of material can retain, typically expressed in g water / g material. The first core layer 110 and the second core layer 120 can be composed of different material structures and fiber types.

[0026] In one embodiment, the second core layer 120 is a mesh fabric with a water retention range of 1 to 7 g / g. The material constituting the mesh fabric can be cotton, linen, polyester, nylon, etc.; the water retention of hydrophilic fibers such as cotton and linen is 3 to 8 g / g, and the water retention of hydrophobic fibers such as polyester and nylon is 1 to 3 g / g.

[0027] In one embodiment, the first core layer 110 is a nonwoven fabric, which may be a hydroentangled / needle-punched nonwoven fabric with high porosity and a water retention range of 5 to 15 g / g; or it may be a meltblown / spunbond nonwoven fabric with a dense structure and a water retention of approximately 3 to 8 g / g.

[0028] A core layer with better absorbency can quickly absorb water and be used for humidification, resulting in higher humidification efficiency. A core layer with relatively lower absorbency, while having lower absorption efficiency, can retain moisture better, leading to longer-lasting humidification. The first core layer 110 and the second core layer 120 complement each other; the core material 10 can absorb water more efficiently and retain it better, resulting in a longer-lasting humidification process. Understandably, the thickness of the first core layer 110 and the second core layer 120 can be adjusted according to usage requirements. For example, for applications requiring higher humidification output, the thickness of the more absorbent core layer can be increased; conversely, for applications requiring longer-lasting humidification, the thickness of the less absorbent core layer can be increased.

[0029] The core material 10 provided in this application, with its first core layer 110 and second core layer 120 complementing each other, offers higher humidification efficiency and better humidification durability. The core material 10 can better adapt to different humidification scenarios and meet various humidification needs.

[0030] The first core layer 110 may include a nonwoven fabric. The first core layer 110 can have better water absorption than the second core layer 120, and its water absorption efficiency is higher. The nonwoven fabric is a sheet, web, or mat made of oriented or randomly arranged fibers bonded together by friction, cohesion, or bonding, or a combination of these methods. Nonwoven fabrics are made by oriented or random arrangement of short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal, or chemical methods. Nonwoven fabrics have abundant pores, which can generate capillary action to absorb water, resulting in a larger specific surface area, higher water absorption efficiency, and better water storage. Water is more evenly distributed within the nonwoven fabric, leading to more uniform humidification. Nonwoven fabrics have lower costs and simpler manufacturing processes, allowing for lower production costs for the core material 10.

[0031] The nonwoven fabric can be folded. It can be folded in a zigzag pattern along its direction of extension. Folded nonwoven fabric can absorb more water, resulting in better humidification durability. Folded nonwoven fabric also has a larger contact area with air, leading to better humidification. Furthermore, folded nonwoven fabric offers better structural strength and stability, supporting the second core layer 120.

[0032] Reference Figure 1 and Figure 2 The second core layer 120 may include a mesh fabric. The mesh fabric can be understood as a fabric with openings, including woven mesh fabric and knitted mesh fabric. There may be multiple openings on the mesh fabric. These multiple openings can be evenly arranged. The mesh fabric may include a first surface layer, a second surface layer, and connecting threads connecting the first and second surface layers. The first surface layer has a first opening, and the second surface layer has a second opening. The first and second openings can be connected in a one-to-one correspondence, with one first opening and one second opening forming one opening. The mesh fabric can be a three-dimensional fabric. The three-dimensional structure of the mesh fabric can effectively retain moisture, resulting in better continuity of the humidification process. The mesh fabric has lower cost and a simpler manufacturing process, which can further reduce the production cost of the core material 10. Water vapor can more smoothly enter the external space through the openings in the mesh fabric, resulting in higher humidification efficiency.

[0033] The mesh can be woven from polyester fibers and metal wires. The metal wires can better maintain the shape of the mesh openings, resulting in higher humidification efficiency for the core material 10. The overall strength of the second core layer 120 can be higher, making it less prone to damage or deformation during use, and extending the service life of the core material 10.

[0034] Alternatively, the mesh can be woven from glass fiber and aromatic polyamide fiber. Glass fiber has a high melting point, while aromatic polyamide fiber also has good thermal stability. Mesh woven from glass fiber and aromatic polyamide fiber has better heat resistance and can be better applied in high-temperature humidification scenarios.

[0035] Reference Figure 1 The second core layer 120 can be at least partially connected or bonded to the first core layer 110. At least a portion of the structure of the first core layer 110 can be attached to the second core layer 120. The second core layer 120 can be laid flat on the side of the first core layer 110. The first core layer 110 can provide some support for the second core layer 120, making the overall structure of the core material 10 more stable.

[0036] Combined with reference Figure 2 and Figure 3 The second core layer 120 and the first core layer 110 can be spaced apart from each other, and a connecting fiber 130 connects the second core layer 120 and the first core layer 110. The distance between the first core layer 110 and the second core layer 120 can be set according to usage requirements. Water vapor conversion can occur on both the first core layer 110 and the second core layer 120. Furthermore, water on the first core layer 110 and the second core layer 120 can be transferred through the connecting fiber 130. The overall moisture distribution of the core material 10 can be more uniform, the water vapor conversion efficiency is higher, and the humidification efficiency is higher.

[0037] Among them, reference Figure 3 The connecting fiber 130 can be a polyamide fiber, such as nylon 66 fiber. The shape of the connecting fiber 130 can be customized according to application requirements; for example, the connecting fiber 130 can be spiral-shaped to improve the contact efficiency between air and water, resulting in smoother airflow. The cross-sectional perimeter of the connecting fiber 130 can be 80μm to 120μm. For example, the cross-sectional perimeter of the connecting fiber 130 can be 80μm, 100μm, or 120μm. The number of connecting fibers 130 can be 8 to 12; for example, the number of connecting fibers 130 can be 8, 10, or 12.

[0038] Alternatively, the connecting fiber 130 can be made of polyester fiber and can be arranged in a spiral shape to improve the contact efficiency between the air and water, resulting in smoother airflow. The cross-sectional perimeter of the connecting fiber 130 can be 180μm to 220μm. For example, the cross-sectional perimeter of the connecting fiber 130 can be 180μm, 200μm, or 220μm. The number of connecting fibers 130 can be 18 to 22, for example, 18, 20, or 22.

[0039] The first core layer 110 can be made of irregularly shaped cross-section fibers. Adjacent irregularly shaped cross-section fibers are more likely to clump together, forming a large number of tiny capillary channels with strong capillary effect, resulting in high water absorption efficiency. Furthermore, the specific surface area of ​​irregularly shaped cross-section fibers is larger than that of ordinary circular cross-section fibers of the same fineness, resulting in a larger contact area with water and higher humidification efficiency. The first core layer 110 made of irregularly shaped cross-section fibers has larger gaps between the fibers, improving air permeability. When air passes through the first core layer 110, moisture on the surface of the irregularly shaped cross-section fibers can evaporate more quickly and be carried away by the airflow, further enhancing humidification efficiency.

[0040] Irregularly shaped cross-section fibers can include hollow triangular cross-section fibers. Under the same outer diameter conditions, hollow triangular cross-section fibers have a relatively lower degree of surface tortuosity. The structural stability of the first core layer 110 can be higher, the processing difficulty is lower, and the cost is lower.

[0041] Alternatively, irregularly shaped cross-section fibers can include hollow hexagonal cross-section fibers. Hollow hexagonal cross-section fibers have a relatively larger specific surface area, allowing for more efficient absorption and release of moisture. Furthermore, hollow hexagonal cross-section fibers exhibit better structural stability, resulting in a more uniform stress distribution under external forces, effectively dispersing stress and improving the structural strength of the first core layer 110. The arrangement of hollow hexagonal cross-section fibers can be more regular, forming relatively regular and uniform pores, facilitating the smooth passage of air and moisture.

[0042] Alternatively, irregularly shaped cross-section fibers can include hollow pentagonal cross-section fibers. Compared to centrally triangular cross-section fibers, hollow pentagonal cross-section fibers have a greater degree of surface curvature, a larger specific surface area, and a higher moisture adsorption capacity. Hollow pentagonal cross-section fibers also exhibit better structural stability, with the first core layer (110) showing greater strength and durability.

[0043] The second core layer 120 can be detachably connected to the first core layer 110. During use, the second core layer 120 can be removed for cleaning or maintenance of the core material 10, making the process more convenient and efficient. The second core layer 120 can be connected to the first core layer 110 using either adhesive hooks or hooks.

[0044] The second core layer 120 can be disposed around the outer periphery of the first core layer 110. The second core layer 120 can more fully cover the first core layer 110, and the water volume and evaporation rate of the first core layer 110 are more evenly distributed. The first end of the second core layer 120 is connected to a first adhesive hook, and the tail end of the second core layer 120 is connected to a second adhesive hook. The second core layer 120 and the first core layer 110 are detachably connected through the cooperation of the first adhesive hook and the second adhesive hook.

[0045] Combined with reference Figure 1 and Figure 2The first core layer 110 can have a higher water absorption rate than the second core layer 120, and the second core layer 120 can be disposed on the outside of the first core layer 110. The first core layer 110, located on the relatively inner side, can absorb water quickly, while the second core layer 120, located on the relatively outer side, can retain moisture better. The core material 10 can have a higher water absorption efficiency and better humidification durability.

[0046] According to another aspect of this utility model, a humidifier is also provided. This humidifier may include any of the aforementioned core materials 10. Since the core material 10 adopts the technical solutions of any of the above embodiments, the humidifier at least has the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here. Furthermore, the humidifier may also include a housing, within which a water spraying component and a fan assembly are disposed. The water spraying component sprays water onto the core material 10, and the fan assembly blows air onto the core material 10 to improve evaporation efficiency.
