Cyclone dust collecting apparatus for a vacuum cleaner

A cyclone dust collecting apparatus, comprising:

• a cylindrical-type cyclone body having an upper opening;
• an upper wall removably connected with an upper end of the cyclone body, the upper wall for opening and closing the upper opening of the cyclone body;
• a suction pipe connected with one side of the cyclone body in order to guide air, which has been drawn into the cyclone body through a suction unit, into the cyclone body;
• and
• a discharge pipe for discharging clean air to outside of the cyclone body after dust has been centrifugally separated in the cyclone body,
• wherein the suction pipe extends into the cyclone body and protrudes into the cyclone body, and the drawn air is guided in a direction tangential to the cyclone body by a front end protruded into the cyclone body;
• and
• a guide member protruding from the lower side of the upper wall in order to guide the air, which whirls along the inner circumference of the cyclone body after being drawn into the suction pipe, to a side underneath the suction pipe,
• wherein the guide member further comprises a sloping side for connecting the lower side of the suction pipe with the upper wall of the cyclone body placed at an upper part of the suction pipe.
