[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the filtration device of this utility model for a high-efficiency air purifier includes a purifier housing 1. An air inlet pipe 2 is installed on the purifier housing 1. Multiple rings 3 are stacked inside the air inlet pipe 2. The multiple rings 3 are combined to form a pipe that is connected vertically. Filter screens 4 with different pore sizes are installed inside the rings 3 respectively. A top cover 9 is installed on the uppermost ring 3 through a hinge. Multiple bottom covers 10 are installed on the lowermost ring 3 through a hinge. A positioning port 11 is vertically provided on one side of the air inlet pipe 2. A positioning plate 5 is provided inside the positioning port 11 to position the multiple rings 3.

[0021] In this embodiment, the inner side of the positioning plate 5 is provided with a positioning groove at each ring 3. The outer ring surface of the ring 3 protrudes to form a positioning part 12 at the positioning groove. The positioning part 12 is inserted into the positioning groove. One end of the positioning plate 5 is bent outward to form a fixing part 6. The fixing part 6 is provided with a first screw hole. The purifier housing 1 is provided with a second screw hole at the first screw hole. The first screw hole and the second screw hole are threaded with a hand-tightening bolt 7 to lock and fix the positioning plate 5.

[0022] In this embodiment, the end of the air inlet pipe 2 away from the top cover 9 is widened outward, and the bottom cover 10 is opened and placed in the widened opening.

[0023] In this embodiment, the hinge is a damping hinge, which can position the rotated top and bottom covers, thereby covering the opening of the pipe.

[0024] In this embodiment, the diameter of the ring 3 is the same as the inner diameter of the air inlet pipe 2. Each ring 3 has a positioning hole 8 on one end face. The bottom ring 3 and the remaining ring 3 all have a protruding positioning post on the other end face. The positioning posts are inserted into the positioning holes 8 of the adjacent ring 3. The positioning posts and positioning holes can position the rings vertically and vertically, avoiding misalignment between the rings.

[0025] In this embodiment, a rubber layer is installed on the inner ring surface of the air inlet pipe 2, and the rubber layer is in contact with the outer ring surface of the ring body 3, which increases the sealing between them.

[0026] During installation, first insert the positioning part on the ring into the positioning groove of the positioning plate, and then insert the ring into the air inlet pipe in one go through the positioning plate. The positioning plate can ensure the movement position of the ring until the fixing part contacts the end face of the purifier housing. The positioning plate and the ring can be fixed by hand-tightening the bolts.
