Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, specifically to a humidifying fabric, core material, and humidifier. Background Technology

[0002] A humidifier comprises a fan assembly, a spray nozzle, and a humidifier core. The spray nozzle sprays water onto the core, wetting the humidifying fabric within. The fan assembly blows air onto the humidifying fabric; the air passes over the fabric, causing the water to evaporate. The evaporated water vapor is then blown out of the humidifier to humidify the external space. The performance of the humidifying fabric significantly impacts the humidification effect of the humidifier. Developing a humidifying fabric that provides more uniform humidification and higher efficiency is a challenge the industry needs to address. Utility Model Content

[0003] According to one aspect of the present invention, a humidifying fabric is provided. The humidifying fabric includes a first web layer and a second web layer, the first web layer and the second web layer being spaced apart and connected by connecting fibers. The first web layer, the second web layer, and the connecting fibers all have water-retaining properties, wherein the water-retaining properties of the connecting fibers are greater than or equal to 1.2 g / g of water retention per unit weight, and the water-retaining properties of the first web layer are greater than or equal to 1.2 g / g of water retention per unit weight.

[0004] The humidifying mesh fabric provided in this application has water-retaining properties in its first mesh layer, second mesh layer, and connecting fibers, allowing for better moisture absorption and a moist state, resulting in superior humidification. The connecting fibers have a water retention capacity greater than or equal to 1.2 g / g per unit area. On one hand, the connecting fibers connect the first and second mesh layers, allowing water to flow between them, thus equalizing the moisture content on both layers and achieving a more uniform humidification effect. On the other hand, the connecting fibers have good water retention, resulting in a higher moisture content and a greater amount of converted water vapor. While the connecting fibers transfer water between different mesh layers, water at various points on the first and second mesh layers and the connecting fibers can be converted into water vapor, resulting in a larger total surface area, higher humidification efficiency, and a better humidification effect.

[0005] For example, a first mesh layer has a first opening, a second mesh layer has a second opening, at least a portion of the first opening corresponds to the second opening, and a connecting fiber connects the outer edge of the first opening and the outer edge of the second opening.

[0006] For example, the outer edge of the first opening is provided with a plurality of first holes, and the outer edge of the second opening is provided with a plurality of second holes, and the connecting fiber passes through the first holes and the second holes.

[0007] For example, the water retention per unit weight of the connecting fiber is 1.2 g / g to 2.8 g / g.

[0008] For example, the connecting fiber is a synthetic fiber; or,

[0009] The connecting fibers are natural fibers; or,

[0010] The connecting fibers are regenerated fibers.

[0011] For example, the surface of the connecting fiber is formed with an uneven hydrophilic layer.

[0012] For example, the uneven hydrophilic layer is made of silicon dioxide.

[0013] For example, the connecting fibers have an antibacterial layer.

[0014] According to another aspect of this invention, a core material suitable for liquid wetting is also provided. This core material comprises any of the aforementioned humidifying fabrics.

[0015] According to another aspect of the present invention, a humidifier is also provided. The humidifier includes the aforementioned core material.

[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 utility model provides a humidifying fabric in its embodiment. (Refer to reference...) Figure 1 and Figure 2The humidifying fabric 10 may include a first web layer 110 and a second web layer 120. The first web layer 110 and the second web layer 120 are spaced apart, and a connecting fiber 130 is present between them. The first web layer 110 may be located inside the second web layer 120. The first web layer 110 and the second web layer 120 may be made of the same material or different materials. The first web layer 110 and / or the second web layer 120 may be a fabric made of yarn. The first web layer 110 and / or the second web layer 120 may be made of nylon fiber and glass fiber. The first web layer 110, the second web layer 120, and the connecting fiber 130 all have water retention properties, wherein the water retention property of the connecting fiber 130 may be greater than or equal to 1.2 g / g of water retention per unit weight, and the water retention property of the first web layer 110 may be greater than or equal to 1.2 g / g of water retention per unit weight. The water retention per unit weight of the connecting fiber 130 can be 1.2 g / g, 2.4 g / g, 2.8 g / g, or 3.4 g / g, etc. The water retention per unit weight of the first web layer 110 can be 1.2 g / g, 2.4 g / g, 2.8 g / g, or 3.4 g / g, etc. The water retention per unit weight of the connecting fiber 130 can differ from that of the first web layer 110. The water retention of the second web layer 120 can be greater than or equal to a water retention per unit weight of 1.2 g / g. The water retention per unit weight of the second web layer 110 can be 1.2 g / g, 2.4 g / g, 2.8 g / g, or 3.4 g / g. The water retention per unit weight of the connecting fiber 130 can differ from that of the second web layer 120. The water retention range of the first web layer 110, the second web layer 120, and the connecting fiber 130 can be 1–7 g water / g material. The material constituting at least one of the first web layer 110, the second web layer 120 and the connecting fiber 130 can be cotton, linen, polyester, nylon, etc.; the water retention of hydrophilic fibers such as cotton and linen is 3 to 8 g / g per unit weight, and the water retention of hydrophobic fibers such as polyester and nylon is 1 to 3 g / g per unit weight.

[0026] During use, the water spraying device sprays water onto the humidifying fabric 10, keeping the first web layer 110, the second web layer 120, and the connecting fibers 130 moist. The fan assembly blows air, converting the water on the first web layer 110, the second web layer 120, and the connecting fibers 130 into water vapor, which is then carried by the airflow to the external space, thus humidifying the external environment.

[0027] The first web layer 110, the second web layer 120, and the connecting fiber 130 possess water-retention properties, allowing them to better absorb moisture and remain moist, resulting in better humidification. The connecting fiber 130 has a water retention capacity greater than or equal to 1.2 g / g. On one hand, the connecting fiber 130 connects the first web layer 110 and the second web layer 120, allowing water to flow between them, balancing the moisture content and achieving more uniform humidification. On the other hand, the connecting fiber 130's superior water retention and higher internal moisture content result in a greater amount of converted water vapor. While the connecting fiber 130 transfers water between different web layers, water at various points on the first web layer 110, the second web layer 120, and the connecting fiber 130 can be converted into water vapor, resulting in a larger total surface area, higher humidification efficiency, and better humidification effect of the humidifying fabric 10.

[0028] Combined with reference Figure 1 and Figure 2 The first mesh layer 110 may have a first opening 1110, and the second mesh layer 120 may have a second opening 1210. The shape of the first opening 1110 may be the same as or different from the shape of the second opening 1210. At least a portion of the first opening 1110 corresponds to the second opening 1210, and a connecting fiber 130 connects the outer edge 1120 of the first opening and the outer edge 1220 of the second opening. The connecting fiber 130 is disposed at the outer edge 1120 of the first opening and the outer edge 1220 of the second opening, providing installation conditions for the connecting fiber 130, and making the connection between the connecting fiber 130 and the first mesh layer 110 and the second mesh layer 120 more stable. Along the direction of water vapor flow, the first opening 1110 and the second opening 1210 may partially overlap, and a flow channel may be formed between the first opening 1110 and the second opening 1210, through which water vapor flows from the first opening 1110 through the flow channel to the second opening 1210. At least a portion of the structure of the connecting fiber 130 may be located within the flow channel. There may be multiple first ports 1110 and multiple second ports 1210. At least a portion of the multiple first ports 1110 may correspond to a second port 1210.

[0029] Combined with reference Figure 1 and Figure 2The outer edge 1120 of the first opening can be provided with multiple first holes 1130, and the outer edge 1220 of the second opening can be provided with multiple second holes 1230. The multiple first holes 1130 can have the same or different shapes. The multiple second holes 1230 can have the same or different shapes. A connecting fiber 130 can be inserted between the first holes 1130 and the second holes 1230. The multiple first holes 1130 are connected sequentially, and the connecting fiber 130 can be inserted into the overlapping portion of two adjacent first holes 1130. The multiple second holes 1230 are connected sequentially, and the connecting fiber 130 can be inserted between two adjacent second holes 1230. The provision of the first holes 1130 can increase the surface area of ​​the first mesh layer 110, resulting in better humidification. The provision of the second holes 1230 can increase the specific surface area of ​​the second mesh layer 120, resulting in better humidification. The connecting fiber 130 is inserted between the first hole 1130 and the second hole 1230, making the overall structure of the humidifying fabric 10 more stable.

[0030] The water retention capacity per unit weight of the connecting fiber 130 can be from 1.2 g / g to 2.8 g / g. For example, the water retention capacity per unit weight of the connecting fiber 130 can be 1.2 g / g, 1.6 g / g, 2.0 g / g, 2.4 g / g, or 2.8 g / g, etc. With more moderate water retention, the water content on the connecting fiber 130 can be more balanced during operation, which can better balance the water transfer efficiency between the first web layer 110 and the second web layer 120, as well as the humidifying effect of the humidifying fabric 10.

[0031] The connecting fiber 130 can be a synthetic fiber. For example, the synthetic fiber can be polyester fiber, polyamide fiber, polyacrylonitrile fiber, polypropylene fiber, polyvinyl chloride fiber, or polyvinyl alcohol acetal fiber. Synthetic fibers have better strength and abrasion resistance, resulting in a longer service life for the humidifying fabric 10. They also have more stable chemical properties and a more stable humidification effect, making them suitable for various application scenarios.

[0032] Alternatively, the connecting fiber 130 can be a natural fiber. For example, natural fibers can be cotton yarn, wool, silk, or hemp. Natural fibers have better hydrophilicity and water retention, can quickly absorb moisture and maintain a moist state for a long time, and can stably release moisture during humidification, resulting in a more stable humidification effect.

[0033] Alternatively, the connecting fiber 130 can be a regenerated fiber. For example, the regenerated fiber can be lyocell fiber or viscose fiber. Regenerated fibers have good water absorption and retention properties, can absorb moisture and retain it for a certain period of time, and provide a stable humidification effect.

[0034] A textured hydrophilic layer (not shown in the figure) can be formed on the surface of the connecting fiber 130. Multiple textured structures can be formed on the surface of the connecting fiber 130. This textured hydrophilic layer increases the roughness of the connecting fiber 130 surface, intercepting some fine particles and impurities in the water. Water droplets are less likely to remain on the textured hydrophilic layer, allowing water to be converted into water vapor more uniformly. The connecting fiber 130 has a larger surface area, allowing water to evaporate more efficiently, resulting in higher humidification efficiency.

[0035] The textured hydrophilic layer can be made of silica. Silica has a certain degree of hydrophilicity, allowing water to spread across the textured hydrophilic layer and form a low contact angle. The textured hydrophilic layer made of silica better meets the requirements for the hydrophilicity of the connecting fibers 130. Silica also has a certain degree of antibacterial properties, reducing bacterial growth on the surface of the connecting fibers 130 and extending the service life of the humidified fabric 10.

[0036] The connecting fiber 130 may have an antibacterial layer. An antibacterial agent can be added to the connecting fiber 130; this agent can be inorganic, organic, or a variety of natural extracts, such as copper, zinc, graphene, phenols, and plant-derived organic acids. The antibacterial layer can be located on the outer surface of the connecting fiber 130. This antibacterial layer can further reduce bacterial growth on the surface of the connecting fiber 130, extending the service life of the humidifying fabric 10.

[0037] According to another aspect of this invention, a core material suitable for liquid wetting is also provided. (See reference 1) Figure 1 and Figure 3 The core material 1 may include any of the aforementioned humidifying fabrics 10. The core material 1 may include a support (not shown in the figure), and the humidifying fabric 10 may be mounted and supported on the support. The humidifying fabric 10 may be a single layer or multiple layers, and multiple layers of humidifying fabric 10 may be stacked. The number of humidifying fabrics 10 can be set according to usage requirements; for example, the core material 1 may have 2 to 6 layers of humidifying fabric 10 stacked together. The humidifying fabric 10 can be adjusted according to the shape of the core material 1. For example, when the core material 1 is cylindrical, the humidifying fabric 10 is rectangular, with the ends connected to form a cylinder, and the ends can be sewn together. Since this humidifying fabric 10 adopts the technical solution of any of the above embodiments, the core material 1 at least has the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated further here.

[0038] According to another aspect of the present invention, a humidifier is also provided. The humidifier includes the aforementioned core material 1. This humidifier possesses at least the beneficial effects of the technical solutions described in the above embodiments, which will not be elaborated further here. Furthermore, the humidifier may also include a housing, within which a water spraying element and a fan assembly are disposed.
