The lower end of the air inlet duct is connected to a filter device, and the upper end of the air inlet duct is connected to a centrifugal fan;

The air inlet of the centrifugal fan is connected to the air inlet duct, and the air outlet of the centrifugal fan is connected to the air outlet;

The air outlet is arranged between the centrifugal fan and the casing, and the air outlet is a hollow cylindrical cavity.

As an improvement, a tool box is provided in the air inlet hood, which is convenient for storing simple cleaning tools.

As an improvement, the front of the air inlet hood is provided with a buckle, and the buckle fixes the two pieces of the air inlet hood to ensure that when the air purifier is working, the air inlet hood will not shake at will to affect the work.

Compared with the prior art, the utility model has the advantages that: the casing is cylindrical, and the air inlet is much larger than that of the vertical box; the split air inlet hood is convenient for the replacement of the filter device; The air inlet hole is conducive to air filtration.
