摘要

A dust collection assembly of a vacuum cleaner is provided. The dust collection assembly includes a dust collecting box (100), a filter (170), a flow guide unit (150), an exhaust guider (140), and an upper cover (120). The dust collecting box (100) and the flow guide unit (150) are integrally formed in a single body. The dust collecting box (100) includes a first (110') and second (110'') dust collecting spaces for collecting foreign objects. The filter is disposed in the inside of the dust collecting space to primarily filter foreign objects during operation of a cyclone. The flow guide unit (150) guides airflow and has small cyclones (160) integrally formed therein, for secondarily filtering the foreign objects in air. The exhaust guider (140) guides airflow and has a plurality of discharge holes through which air filtered by the small cyclone flows. The upper cover (120) is disposed on the upper side of the exhaust guider (140).
