ABSTRACT:
A dust collecting container includes an annular lower portion and an annular upper portion having a first circumferential wall interposed between first annular upper and lower ends to define a first columnar chamber of a first length in a first axial direction, and a first annular flange which extends outwardly and radially from the first lower end. The lower portion has a second circumferential wall between second annular upper and lower ends to define a second columnar chamber of a second length in a second axial direction greater than the first length and of an inner diameter larger than an outer diameter of the first circumferential wall, and a second annular flange that extends radially and outwardly from the second annular upper end such that when the first annular lower end is brought towards the second annular upper end with the first axial direction aligned with the second axial direction, the first annular flange will superimpose on and abut against the second annular flange to form a fluid communication path between the first and second chambers. A bottom plate is sealingly and securely attached to the second lower end.
