Referring to Figures 1 and 3, a pneumatic plush trimmer driven by a centrifugal fan includes:

The body 1 and the plush trimming disc 2 detachably mounted on the body 1, the body 1 comprises a hollow casing 11 and a pile trimming chamber 13 and a wind wheel chamber 14 formed in the casing 11, a plush trimming chamber 13 is spaced apart from the wind wheel chamber 14.

The housing assembly 1 further includes a centrifugal fan 3 disposed within the wind turbine chamber 14 in which the pile trimming disc 2 is mounted.

Referring to Figures 1 and 3, the outer wall of the casing 11 is provided with a plurality of power duct air inlets 113 leading to the wind turbine chamber 14.

Further, the pile trimming chamber 13 is spaced apart from the wind wheel chamber 14, and the top of the wind wheel chamber 14 is provided with a power duct 121.
