[0040] like Figure 5 As shown, combined Figure 2 , Figure 4As shown, the air inlet shell 11 includes an air inlet cylinder 111 and an air inlet base plate 112. The air inlet cylinder 111 is a cylindrical structure with openings at both ends. The air inlet cylinder 111 has a plurality of arrays of air inlets. The air inlet base plate 112 is a disc-shaped structure with a grid-shaped air inlet. The top of the air inlet cylinder 111 has a groove, and the bottom of the air inlet cylinder 111 has a step structure. The air inlet base plate 112 has a boss that docks with the step structure, and the step structure and the boss are just snapped together. The air inlet cylinder 111 can be connected to the air inlet base plate 112 by welding, snapping, threaded connection, etc. The filter element 5 is installed on the top surface of the air inlet base plate 112. The filter element 5 is cut into a circle, and its size is slightly larger than the inner diameter of the air inlet cylinder 111, so that the filter element 5 can fit the air inlet cylinder 111 more stably.

The rotation method can be a groove and a flange method, or a threaded connection, or a direct gap connection method. While ensuring a certain friction force, it can also rotate. The friction force is ensured to avoid being too loose, and try to ensure that the shell 1 can maintain a state without sliding after rotating to a certain angle. The first rotating cylinder 3 and the second rotating cylinder 4 have a buckle 31, which can be used to fix on the brim of the hat, or other places. The buckle 31 is fixed to the first rotating cylinder 3 and the second rotating cylinder 4 by bonding, screw connection, etc. When the buckle 31 is not needed, the buckle 31 can be removed.

[0045] The filter element 5 is a PM2.5 filter cotton, which can effectively filter out tiny particles such as haze, viruses, bacteria, pollen, etc. in the air and purify the air.

[0046] Working process of this embodiment:

[0047] The wind is introduced from the air inlet through the fan assembly 2 and filtered through the filter element 5, and then the haze, viruses, bacteria, pollen and other tiny particles in the air can be effectively filtered out and blown out from the air outlet.
