[0035] In order to better understand the above technical solutions, the technical solutions in the embodiments of the present disclosure are described below in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present disclosure and specific features in the embodiments are detailed descriptions on the technical solutions in the embodiments of the present disclosure, and are not intended to limit the technical solutions in the present disclosure. The embodiments in the present disclosure and technical features in the embodiments may be combined with each other in a non-conflicting situation.

[0036] An embodiment of a first aspect of the present disclosure provides evaporator 10. As shown in FIGS. 1-8, the evaporator 10 includes first frame 100 and moisture retention assembly 200. The moisture retention assembly 200 includes fabric 210. At least part of a periphery of the fabric 210 is detachably connected to the first frame 100.

[0037] In this embodiment, the fabric 210 is also called a woven fabric or a textile. Because of the excellent extensibility and water-absorbing capacity of the fabric 210, moisture can be absorbed to a surface or an interior of the fabric 210. The humidity of the air is increased by evaporating the moisture.

[0038] Exemplarily, the fabric 210 may be a single-layer porous substrate woven from either synthetic fibers (like polyester and nylon) or natural fibers (like cotton yarn). With a surface including regularly distributed geometric openings (such as regular hexagons or squares with diagonals of 2-12 mm), the fabric 210 has a mesh density of 5-30 meshes / cm². As a core layer of the evaporator 10, the textile is connected to another textile via vertical or curved connecting fibers (4-50 fibers per bundle), forming through-going three-dimensional (3D) air channels. Surfaces of the fibers may be subjected to hydrophilic or hydrophobic treatment to regulate the moisture retention capacity (the water retention amount is 1.2-2.8 g / g), with the water film adhesion enhanced through a micro-scale roughness (Ra ≤ 50 μm). Due to the low-resistance design (with a pressure loss of ≤ 20 Pa when the face velocity is 1 m / s) and the anti-scaling property, the fabric is suitable for rotary, immersion-type, and drip-type humidification devices, achieving efficient and stable humidification and improving the humidity at a rate of > 0.8 g / (m³·min).

[0039] Exemplarily, the fabric 210 may be a 3D structured filter substrate, which is formed by vertically or curvilinearly connecting two woven substrates with regular openings (such as regular hexagons with diagonals of > 3 mm) via a plurality of connecting fiber bundles (4-50 fibers per bundle, with an outer perimeter of 45-450 μm for each single fiber). The fabric 210 makes use of the inter-fiber capillary action and surface micro-scale concave-convex structures to retain water (the water retention amount is 1.45-2.55 g / g), while ensuring the low resistance when air passes through the through-going openings. With the fibers made of polyester, nylon, or cotton yarn, the fabric is suitable for rotary cylinders or banded structures to achieve uniform humidification through hydrophilic / hydrophobic treatment or addition of an antibacterial agent. Compared with traditional honeycomb structures, the 3D fiber network increases the gas-liquid contact area by 3 times, effectively inhibiting scale clogging. With high humidification efficiency (>60% RH at the face velocity of 1 m / s) and low energy consumption, the fabric is suitable for long-term stable humidification scenarios such as air purifiers.

[0040] When the moisture retention assembly 200 is mounted, the fabric 210 is connected to the first frame 100. The at least part of the periphery of the fabric 210 is located by the first frame 100, such that an edge of the fabric 210 is fixed, and the fabric 210 is deployed, preventing deformation or collapse of the moistened fabric 210. When the moisture retention assembly 200 is detached, the moisture retention assembly 200 is separated from the first frame 100, so as to clean and replace the fabric 210.

[0041] By fixing all or part of the edge of the fabric 210 through the first frame 100, the fabric 210 is circumferentially fixed, such that the mounted fabric 210 is more stable, and the fabric 210 can be stably deployed with a sufficient contact area with the gas flow and water flow. This improves the moisture retention effect and evaporation effect of the fabric 210, and improves the moisture retention efficiency of the moisture retention assembly 200. With the detachable connection between the first frame 100 and the moisture retention assembly 200, the present disclosure realizes fixation and detachment of the moisture retention assembly 200, and facilitates cleaning and replacement of the fabric, improving the user experience.

[0042] Exemplarily, the first frame 100 may be made of metal or hard plastic with high hardness and corrosion resistance. For example, the first frame 100 is made of aluminum alloy, polypropylene, or glass fiber-reinforced nylon. The fabric 210 may be made of a material with good water-absorbing capacity and water retention capacity. For example, the fabric 210 is made of a gauze and a non-woven fabric.

[0043] In an embodiment provided by the present disclosure, as shown in FIGS. 1-8, mounting portion 110 is disposed on the first frame 100. The moisture retention assembly 200 further includes mating member 220. The mating member 220 is detachably connected to the mounting portion 110.

[0044] In the embodiment, the first frame 100 is circumferentially provided with the mounting portion 110. The mating member 220 is disposed on the fabric 210. When the fabric 210 is deployed, the mating member 220 is circumferentially located on an outer edge of the fabric 210, and can cooperate with the mounting portion 110. The fabric 210 is detachably connected to the first frame 100 through the mating member 220. When the moisture retention assembly 200 is mounted, by engaging the mating member 220 and the mounting portion 110, the periphery of the fabric 210 is located by the first frame 100, such that the edge of the fabric 210 is fixed, and the fabric 210 is deployed. When the moisture retention assembly 200 is detached, by disengaging the mating member 220 and the mounting portion 110, the mating member 220 is separated from the mounting portion 110, thereby taking out the moisture retention assembly 200 to facilitate cleaning and replacement of the fabric 210.

[0045] Through cooperation between the mating member 220 and the mounting portion 110, the first frame 100 can be detachably connected to the moisture retention assembly 200, thereby enabling fixation and detachment of the moisture retention assembly 200, simplifying mounting and detachment of the fabric 210, facilitating the cleaning and replacement of the fabric, and enhancing the user experience.

[0046] In an embodiment provided by the present disclosure, as shown in FIG. 1, FIG. 2, FIG. 5, FIG. 6, FIG. 7, and FIG. 8, the moisture retention assembly 200 further includes second frame 230. The mating member 220 is disposed on the second frame 230. The fabric 210 is connected to the second frame 230.

[0047] In the embodiment, the mating member 220 is disposed on a periphery of the second frame 230. The second frame 230 is detachably connected to the first frame 100 through the mating member 220. The fabric 210 is connected to the second frame 230. The second frame 230 is configured to provide a structural support for the fabric 210, such that the fabric 210 is deployed when mounted, facilitating circumferential fixation of the fabric 210, preventing the fabric 210 from being twisted or collapsed during mounting, and improving the mounting convenience and mounting efficiency of the fabric 210.

[0048] Exemplarily, the second frame 230 may be made of metal or hard plastic with high hardness and corrosion resistance. For example, the second frame 230 is made of aluminum alloy, polypropylene, or glass fiber-reinforced nylon.

[0049] In an embodiment provided by the present disclosure, as shown in FIG. 1, FIG. 5, FIG. 7, and FIG. 8, the mounting portion 110 is located on an inner wall of the first frame 100. The mating member 220 is located on an outer wall of the second frame 230.

[0050] In the embodiment, since the mounting portion 110 is located on the inner wall of the first frame 100, and the mating member 220 is located on the outer wall of the second frame 230, when the mating member 220 cooperates with the mounting portion 110, the first frame 100 surrounds the second frame 230. This reduces space occupied by the mounted second frame 230 in a height direction, thereby reducing an overall height of the evaporator 10 after assembly, making the evaporator 10 more structurally compact, and saving occupied space of the evaporator 10.

[0051] In another embodiment, as shown in FIG. 6, the mounting portion 110 is located on a bottom wall of the first frame 100, and the mating member 220 is located on a top wall of the second frame 230. When the mating member 220 cooperates with the mounting portion 110, the first frame 100 is located on one side of the second frame 230. This reduces shielding when the mating member 220 cooperates with the mounting portion 110, achieving sufficient operating space when the second frame 230 is connected, and improving mounting convenience of the moisture retention assembly 200.

[0052] In an embodiment provided by the present disclosure, the fabric 210 is detachably connected to the second frame 230.

[0053] In the embodiment, when the fabric 210 needs to be cleaned, the fabric 210 can be separately detached and taken out, facilitating cleaning of the fabric 210. Meanwhile, when the moisture retention assembly 200 needs to be maintained, the fabric 210 can be separately replaced, while the second frame 230 does not need to be replaced, thereby reducing maintenance cost of the moisture retention assembly 200.

[0054] In another embodiment, the fabric 210 is fixed on the second frame 230, and the fabric 210 is deployed on the second frame 230, such that the fabric 210 is mounted more firmly and stably, the assembly step of the moisture retention assembly 200 is reduced, and the moisture retention assembly 200 is mounted more conveniently.

[0055] In an embodiment provided by the present disclosure, as shown in FIG. 1, FIG. 5, FIG. 6, and FIG. 8, the mating member 220 is disposed on first wall 231 of the second frame 230. The periphery of the fabric 210 is connected to second wall 232 of the second frame 230. The second wall 232 is connected to or spaced apart from the first wall 231.

[0056] In the embodiment, the mating member 220 is disposed on the first wall 231 of the second frame 230, and the fabric 210 may be connected to the second wall 232 of the second frame 230. The first wall 231 may be the outer wall of the second frame 230. The second wall 232 may be the inner wall, the top wall, or the bottom wall of the second frame 230. The fabric 210 is connected to the wall of the second frame 230 not provided with the mating member 220, such that the cooperation between the mating member 220 and the mounting portion 110 is not affected by the fabric 210, and the second frame 230 can be smoothly connected to the first frame 100, improving the mounting convenience of the second frame 230.

[0057] In an embodiment provided by the present disclosure, as shown in FIG. 7, the fabric 210 is partially located between an inner wall of the first frame 100 and an outer wall of the second frame 230. The fabric 210 is provided with avoidance hole 211. The avoidance hole 211 is configured to avoid the mating member 220.

[0058] In the embodiment, when the moisture retention assembly 200 is mounted, the fabric 210 is placed over a top of the second frame 230, such that the edge of the fabric 210 covers at least part of the outer wall of the second frame 230. The avoidance hole 211 of the fabric 210 can avoid the mating member 220, preventing the fabric 210 from affecting the connection between the mating member 220 and the mounting portion 110. Then, the mating member 220 passes through the avoidance hole 211 to cooperate with the mounting portion 110, such that the second frame 230 is disposed inside the first frame 100, and the periphery of the fabric 210 is partially clamped between the inner wall of the first frame 100 and the outer wall of the second frame 230. The fabric 210 is directly fixed by clamping the first frame 100 and the second frame 230, eliminating the need for an additional connector on the fabric 210. This simplifies the structure and assembly step of the moisture retention assembly 200 and lowers the cost of the moisture retention assembly 200.

[0059] In an embodiment provided by the present disclosure, as shown in FIGS. 1-8, there are a plurality of mounting portions 110 and a plurality of mating members 220. The plurality of mating members 220 are distributed along the periphery of the fabric 210.

[0060] In the embodiment, the direction indicated by arrow X in FIG. 2 is the circumferential direction of the first frame 100 and the fabric 210. The first frame 100 is circumferentially provided with the plurality of mounting portions 110. The plurality of mating members 220 are uniformly distributed along the circumferential direction of the fabric 210. After the moisture retention assembly 200 is mounted on the first frame 100, the edge of the fabric 210 is circumferentially located, which enhances the uniformity and stability of the location of the fabric 210 by the first frame 100 and improves the fixing effect of the first frame 100 on the fabric 210.

[0061] In an embodiment, a quantity of the mounting portions 110 is the same as a quantity of the mating members 220, so as to prevent the unused mounting portion 110 or mating member 220, enhance the utilization efficiency of the mounting portion 110 and the mating member 220, and reduce the material cost of the evaporator 10.

[0062] In another embodiment, the quantity of the mounting portions 110 is different from the quantity of the mating members 220, such that the moisture retention assembly 200 is mounted at a plurality of positions, improving the mounting efficiency and convenience of the moisture retention assembly 200.

[0063] In an embodiment provided by the present disclosure, as shown in FIG. 2, FIG. 3, FIG. 11, and FIG. 12, a contour of the first frame 100 includes a polygon. The plurality of mounting portions 110 are respectively located at vertices of the polygon, or on edges of the polygon and adjacent to ends of the edges.

[0064] In the embodiment, the contour of the first frame 100 includes the polygon. Exemplarily, the contour of the first frame 100 may be a triangle, a tetragon or a hexagon. The polygon may be an equilateral polygon. As shown in FIG. 3, the plurality of mounting portions 110 are respectively located on the vertices of the polygon. As shown in FIG. 2, the plurality of mounting portions 110 are respectively located on the edges of the polygon, and are adjacent to the ends of the edges relative to midpoints of the edges. By defining positions of the mounting portions 110 on the first frame 100, a locating position of the first frame 100 on the moisture retention assembly 200 is defined. The periphery of the moisture retention assembly 200 can be located more uniformly and stably, optimizing a fixing effect of the moisture retention assembly 200, and meeting locating requirements of the first frame 100 on fabrics 210 of different shapes.

[0065] In an embodiment, a contour of the second frame 230 includes a polygon. The plurality of mating members 220 are respectively located at vertices of the polygon, or on edges of the polygon and adjacent to ends of the edges.

[0066] In an embodiment provided by the present disclosure, the contour of the first frame 100 includes a circle.

[0067] In the embodiment, the contour of the first frame 100 includes the circle. The plurality of mounting portions 110 are uniformly distributed on an edge of the circle. The periphery of the moisture retention assembly 200 can be located more uniformly and stably, optimizing a fixing effect of the moisture retention assembly 200, and meeting locating requirements of the first frame 100 on fabrics 210 of different shapes.

[0068] In an embodiment, the contour of the second frame 230 includes a circle.

[0069] In an embodiment provided by the present disclosure, as shown in FIGS. 1-10, the mounting portion 110 includes at least one of a self-adhesive structure, a hook, a lanyard, a fastener, a slider, a sliding groove and a mounting hole. The mating member 220 includes at least one of a self-adhesive structure, a hook, a lanyard, a fastener, a slider, a sliding groove and a connector configured to cooperate with the mounting portion 110.

[0070] In the embodiment, specific structures of the mating member 220 and the mounting portion 110 are defined. The mating member 220 and the mounting portion 110 are respectively connecting structures that can cooperate with each other, so as to facilitate the processing and mounting of the first frame 100 and the moisture retention assembly 200.

[0071] Exemplarily, the mating member 220 and the mounting portion 110 are respectively self-adhesive structures. The self-adhesive structure may be a hook-and-loop fastener, a burr sticker, or an adhesive strip. As shown in FIG. 2, FIG. 4, FIG. 5, and FIG. 6, the self-adhesive structure may include strip-shaped members that surround an inner side of the first frame 100. Alternatively, there are a plurality of self-adhesive structures. The plurality of self-adhesive structures are arranged at intervals along the circumferential direction of the first frame 100.

[0072] Exemplarily, as shown in FIG. 1, FIG. 2, FIG. 7, and FIG. 10, one of the mating member 220 and the mounting portion 110 is the hook, and the other is the cooperating hook or lanyard.

[0074] Exemplarily, as shown in FIG. 8, the mating member 220 and the mounting portion 110 are respectively the slider and the sliding groove that can cooperate with each other. This reduces a gap between the first frame 100 and the second frame 230, makes the evaporator 10 more structurally compact, and reduces the occupied space of the evaporator 10. Specifically, the sliding groove may be a dovetail groove, so as to improve the fixing effect of the mounting portion 110 on the mating member 220.

[0075] Exemplarily, as shown in FIG. 3, the mating member 220 and the mounting portion 110 are respectively the mounting hole and the connector. Specifically, the mounting hole may be a threaded hole, and the connector may be a bolt or a screw.

[0076] In an embodiment provided by the present disclosure, as shown in FIG. 9, the first frame 100 is provided with mounting groove 120, and the mounting portion 110 is located in the mounting groove 120.

[0077] In the embodiment, the mounting groove 120 is formed on the periphery of the first frame 100, and the mounting portion 110 is located in the mounting groove 120. This reduces a protruding height of the mounting portion 110, shortens a distance between the moisture retention assembly 200 and the first frame 100 after the mating member 220 is engaged with the mounting portion 110, and makes the evaporator 10 more structurally compact.

[0078] Exemplarily, the second frame 230 is provided with the mounting groove 120. The mating member 220 is located in the mounting groove 120. This reduces the protruding height of the mating member 220 and makes the evaporator 10 more structurally compact.

[0079] In an embodiment provided by the present disclosure, the fabric 210 is plate-like, and a plurality of fabrics 210 are stacked.

[0080] In the embodiment, the plurality of plate-like fabrics 210 are stacked, which improves the moisture storage capacity of the fabric 210, thereby improving the moisture retention effect and humidification effect of the moisture retention assembly 200.

[0081] Exemplarily, there are a plurality of first frames 100. The plurality of first frames 100 are respectively connected to the plurality of fabrics 210. Alternatively, there is one first frame 100. The plurality of fabrics 210 are stacked on the first frame 100.

[0082] In another embodiment, the fabric 210 is 3D fabric 210. The mating member 220 is circumferentially distributed on an end surface of the 3D fabric 210.

[0083] An embodiment of a second aspect of the present disclosure provides humidification device 20. As shown in FIG. 13, the humidification device 20 includes air supply unit 21 and the evaporator 10 provided by the embodiment of the first aspect. The air supply unit 21 is opposite to the fabric 210 of the evaporator 10.

[0084] In the embodiment, gas flow blown from the air supply unit 21 can pass through the fabric 210, and moisture in the fabric 210 is transferred to airflow, thereby improving the moisture content in the air and humidifying the air.

[0085] It is to be noted that the humidification device 20 including the evaporator 10 in any of the foregoing embodiments achieves all the beneficial technical effects of the evaporator 10. To avoid redundancy, details are not repeated herein.
