[ What is claimed is:] [1.] A cyclone type dust collector comprising:an air separating chamber having a cylinder at an upper part and a reversed circular cone at a lower part, a dust exhaust aperture disposed at a bottom of the reversed circular cone of the air separating chamber, a clean air exhaust duct disposed concentrically with an axial center of the air separating chamber, a cylindrical air dividing chamber connected to an aperture disposed on an upper wall of the air separating chamber, a dust laden raw air intake duct connected to the cylindrical air dividing chamber along a tangential direction;a plate disposed in parallel to said upper wall and circumscribing said clean air exhaust duct and located at an inner position from an aperture disposed on the upper wall of the air separating chamber with a predetermined distance to thereby provide a clearance between the plate and the upper wall;a plurality of vertical walls disposed on said plate, each of said vertical walls defining a first leg radially extending from said axial center and a second leg radially extending from said axial center, wherein said second leg extends in a direction that is angled with respect to said first leg; anda spiral airflow adjustment and acceleration mechanism having a plurality of spiral airflow adjustment and acceleration grooves to adjust and accelerate the spiral airflow entering the air separating chamber, each of said grooves being defined by two adjacent walls of said plurality of vertical walls, wherein dust laden raw air passes through said plurality of spiral airflow adjustment and acceleration grooves extending toward an outer circumference of said air separating chamber so as to generate spiral airflow toward an inner wall of the outer circumference of said air separating chamber after flowing around the circumference of said clean air exhaust duct.
