Dust collection unit for vacuum cleaner

A dust collection unit for a vacuum cleaner, comprising:

• a first filtering chamber generating a first cyclone airflow, the first filtering chamber having a relatively large diameter;
• a filter disposed in the first filtering chamber, the filter being formed of plastic material;
• a plurality of second filtering chambers discontinuously formed along an outer circumference of the first filtering chamber to receive air passed through the first filtering chamber;
• a first storing chamber for storing foreign objects filtered in the first filtering chamber;
• a second storing chamber for storing the foreign objects filtered in the second filtering chambers, the second storing chamber being formed in an arc-shape;
• a connection plate interconnecting opposite ends of the second storing chamber to define the first filtering chamber, wherein at least a portion of a vertical length of the connection plate overlaps at least a portion of a vertical length of the second storing chamber, and a lower end of the connection plate is offset from a lower end of the second storing chamber creating a lateral opening through which foreign objects pass;
• and
• an exhaust member guiding the air passed through the second filtering chambers in a direction.

A dust collection unit for a vacuum cleaner, comprising:

• a first filtering chamber generating a first cyclone airflow, the first filtering chamber having a relatively large diameter;
• a filter disposed in the first filtering chamber, the filter being formed of plastic material;
• a blocking member selectively coupled to a lower portion of the filter, the blocking member having a diameter that is increased at it goes downward;
• a plurality of second filtering chambers discontinuously formed along an outer circumference of the first filtering chamber to receive air passed through the first filtering chamber;
• a first storing chamber for storing foreign objects filtered in the first filtering chamber;
• a second storing chamber for storing the foreign objects filtered in the second filtering chambers, the second storing chamber being formed in an arc-shape;
