Abstract
An air inlet for a two-stage dust collecting machine is formed in an air-pipe housing in a two stage dust collecting machine, and the air inlet is an rectangular shape formed in the annular wall of the air-pipe housing in the tangent direction. Further, a rectangular pipe is provided to extend out from the rectangular inlet, a circular pipe extends out from the rectangular pipe, and a current guiding member extends inward from the rectangular inlet. Therefore, sucked-in air is guided through the rectangular pipe with a comparative large space to flow through the current guiding member to become a helical current moving along the inner surface of the air-pipe housing, so sucked-in air flows smoothly in the machine, upgrading the two-stage dust collecting function of the machine.
