ABSTRACT:
A hose connector for hose of a dust collector is disclosed. The hose connector has a housing containing a blower, a blade module, a hose and the hose connector includes a covering plate, wherein the center of the covering plate of the hose connector is provided with a through hole and the lower edge next to the hose connector is protruded out an urging edge which can resist against the circumferential edge of the covering plate, and the lower edge of the hose connector is protruded out an engaging block which can engage to the lower inner edge of the through hole of the covering plate, and on the hose connector adjacent to the engaging block, a stopping pad is disposed such that when the stopping pad is at the covering plate of the hose seat the length of the stopping pad facing downward is beyond the top end of the blade module and a curved gap is formed between the stopping pad and the blade module. The hose connector of the present invention improves the efficiency of the dust collector by eliminating turbulence of the blower.
