Abstract
A blowing device includes a casing having an circular wall located eccentrically in the casing. A rotor is rotatably received in the circular wall and a plurality of blades retractably extend from the rotor and contact an inner periphery of the circular wall. A first inlet is defined through the casing and an outlet is defined through the circular wall. A second inlet is defined through the circular wall. A fitting extends through the casing and is engaged with the outlet. When the rotor is rotated in the circular wall, a plurality of partitions are defined by the blades in the circular wall and is sent out from the fitting to blow the wood powder or debris.
