Abstract
An improved dust collector is proposed. The dust collector comprises an upper duct, and a flexible lower flap connected to the upper dust duct, wherein the lower flap is resilient. Preferably, the upper duct has a substantially U-shaped cross-section, whereas the bottom of the duct is open. The lower flap is disposed in the open portion of the inlet. Furthermore, the upper duct inlet and outlet may have corresponding centerlines, whereas the centerline of the upper duct outlet may be offset from the centerline of the upper duct inlet by a predetermined number of degrees, e.g., about 15°. In addition, the dust collector may further include a wire for maintaining the lower flap in an open position.
