[0034] Among them, the bearing assembly is mainly composed of the N-shaped large frame 2, the side plate 5, the top plate 1 and the hand ring 3. The large frame 2 and the side plate 5 form a rectangular surrounding structure to provide a stable support frame. The top plate 1 is installed on the large frame 2 by hinging, and the openable and closable design facilitates maintenance.

[0039] The vortex air duct plates 7 and the auxiliary block 8 jointly form two vortex spiral air ducts, and the double air duct structure makes the air duct have a longer distance to increase, so as to improve the air flow speed and make the air flow more uniform, and compared with four air ducts, the suction force is enhanced; the low-noise fan is installed through an integral air ring to ensure smooth air suction;
