In the embodiment of the present application, the humidification filter screen structure 100 is applied to a purifier (not shown), and the purifier includes an air duct (not shown) and a water tank (not shown) arranged outside the air duct. The humidification filter screen structure 100 includes a cover body 2 and a humidification filter screen assembly 3.
The cover body 2 includes an upper cover 21 and a lower cover 22 which is detachably connected to the upper cover 21. The upper cover 21 and the lower cover 22 mutually enclose a mounting space (not shown) in which the humidification filter screen assembly 3 is mounted. The humidification filter screen assembly 3 includes a water absorbing part 301 and a humidification part 302 which are connected to each other.
In this embodiment, the air duct of the purifier is extended through the inside and outside of the purifier, the water tank of the purifier is configured in a ring shape, surrounding an outside of the air duct. The water absorbing part 301 is extended into the water tank, and the humidification part 302 is communicated with the air duct. Therefore, when the water absorbing part 301 absorbs the moisture in the water tank, the water absorbing part 301 can guide and transfer the moisture to the humidification part 302, so that the humidification part 302 becomes humidified, and when air in the air duct flows through the humidification part 302, the air takes away the water vapor therein and become humidified. In an embodiment, the humidification part 302 is arranged perpendicular to a flow direction of the air in the air duct so that the humidification part 302 is in a windward position, so that when the air flows through the humidification part 302, an contact area between the humidification part 302 and the air can be increased to the greatest extent, and making the humidification effect better.
A material of the cover body 2 may be a plastic material. For example, a terpolymer (ABS) material of acrylonitrile (A), butadiene (B), and styrene (S) monomers is used, which has good flexibility and a surface hardness. When the water absorbing part 301 absorbs water and makes the humidification filter screen assembly 3 as a whole heavier, the cover body 2 can bear the humidification filter screen assembly 3 and prevent loosening or collapsing. In particular, The humidification filter screen assembly 3 can be embedded in the mounting space enclosed by the upper cover 21 and the lower cover 22. The upper cover 21 and the lower cover 22 are both provided at a vent (not labeled) connected to the air duct, so that the humidification filter screen assembly 3 can be closely attached to the upper cover 21 and the lower cover 22, and will not shake due to the existence of gaps after installation. Moreover, the vent enables the humidification part 302 to fully contact with the air in the air duct, which is beneficial to air circulation.
In the embodiments of the present application, the water absorbing part 301 is extended into the water tank of the purifier, and the water absorbing performance of the water absorbing part 301 is used to transfer water to the humidification part 302 connected with the water absorbing part 30, so that the humidification part 302 becomes wet. Since the humidification part 302 of the humidification filter screen assembly 3 is provided in the air duct of the purifier, when the air in the air duct flows through the humidification part 302, the water vapor of the humidification part 302 can be taken away, and the outflow air is humidified. In addition, the humidification filter screen assembly 3 is mounted in the mounting space formed by the cover body 2, so that when the humidification filter screen assembly 3 absorbs water and becomes heavier, the cover body 2 can support and fix it to prevent collapsing. By using the upper cover 21 and the lower cover 22 which are detachably connected together, the humidification filter screen assembly 3 can be conveniently disassembled for scale cleaning and regular maintenance, and the humidification filter screen assembly 3 does not need to be frequently replaced, therefore reducing the cost of users.

In particular, the supporting part 223 is provided in a frame shape, the mounting part 221 is also arranged in a frame shape around the outer side of the supporting part 223, and a size of the mounting part 221 is larger than a size of the supporting part 223, so that a distance is formed between the mounting part 221 and an outer side wall of the supporting part 223. When the mounting part 221 is connected with the upper cover 21, the mounting part 221 is capable of being combined with the outer side wall of the supporting part 223 to form the mounting space for mounting the humidification filter screen assembly 3. The supporting part 223 is extended protrusively toward the upper cover 21, so that a height of the supporting part 223 is higher than a height of the mounting part 221, and the lower cover 22 is integrally formed into an arched structure. When the humidification filter screen assembly 3 and the cover body 2 are assembled, the water absorbing part 301 can better contact the water in the water tank, and the water absorbing effect is better.
In this embodiment, the mounting part 221, the connecting part 222, and the supporting part 223 may be integrally formed by molding, or the mounting part 221, the connecting part 222, and the supporting part 223 may be fixedly connected by a common method in the art such as bonding or welding, and connecting parts 222 may be uniformly provided at intervals to ensure stability of the connection. In this embodiment, a notch 2211 is further formed on a side of the mounting part 221 facing the upper cover 21. When the upper cover 21 and the lower cover 22 enclose, the splicing notch 2211 can be matched with a notch (not shown) of the upper cover 21, so that an outer surface after the upper cover 21 and the lower cover 22 are spliced is flatter.
In one embodiment, referring to
In this embodiment, since the water absorbing part 301 and the humidification part 302 are integrated, there is no splicing gap between the water absorbing part 301 and the humidification part 302, and when the water absorbing part 301 absorbs water, the water can be quickly transferred to the humidification part 302, so that the efficiency of water transfer can be improved and the humidification effect can be improved.
In one embodiment, after the upper cover 21 and the lower cover 22 are closed, a continuous avoidance opening (not shown) is formed in a side wall of the cover body 2, the water absorbing part 301 is connected to an outer side wall of the humidification part 302, the water absorbing part 301 is connected with the humidification part 302 to form a planar structure, and the humidification part 302 is located in the mounting space enclosed by the upper cover 21 and the lower cover 22. The water absorbing part 301 is extended from the avoidance opening and contacts with water in the water tank. At this time, the water is transmitted from the water absorbing part 301 around to the humidification part 302 in the center, and finally carried away by the air in the air duct.

In one embodiment, the first water blocking member 31 or the second water blocking member 32 has a grid structure, or the first water blocking member 31 and the second water blocking member 32 are both arranged to have a grid structure, and specific materials of the first water blocking member 31 and the second water blocking member 32 can be synthetic fibers or nylon materials to form a fish wire-like net structure, and are fixedly connected with the humidification filter screen body 30 by gluing or sewing. In general, a mesh diameter of the grid structure formed in the first water blocking member 31 and the second water blocking member 32 is at least 0.02 mm and not more than 0.05 mm. When moisture of the humidification part 302 attempts to form water droplets to drop on the air duct or blow out from the air duct, the first water blocking member 31 and the second water blocking member 32 can prevent the formation of water droplets, and make the moisture adhere to the surface of the first water blocking member 31 or the second water blocking member 32, forming a water film in the mesh of the grid and evaporating with the flow of air.
