Each air inlet includes a bottom plate and a wind guiding plate. An air inlet cavity is formed between the adjacent wind guiding plates and the bottom plate. A V-shaped air flow guiding member or an assembly column is arranged at the inner end of the wind guiding plate. The size of the air inlet cavity gradually decreases along the air flow direction, and the air inlet cavity communicates with a separation cavity;

[0008] A dust guiding cone cylinder, which is connected to the bottom of the cylinder.

[0016] The air deflector is an arc-shaped plate arranged in a spiral manner.

[0017] In summary, due to the adoption of the above technical solution, the present utility model has the following

[0018] beneficial effects compared with the prior art:

[0019] Through the spiral design of multiple air inlets, the centrifugal guiding of the air deflector and the gradually narrowing design of the air inlet cavity, the air flow of this cyclone cone structure is accelerated. Cooperating with the V-shaped deflector, the air flow disturbance at the joints of each air inlet can be reduced, thereby improving the separation efficiency of dust and air flow, ensuring stable and sufficient dust collection and clean air discharge; the air guiding structures of adjacent air inlets are shared and assembled with the connecting frame, reducing the size of the spiral air inlet assembly and improving space utilization.
