SUCTION BRUSH OF VACUUM CLEANER

摘要

PURPOSE: A suction brush of a vacuum cleaner is provided to improve a cleaning efficiency and to prevent dust from sticking into a cleaning section of the suction brush by striking the cleaning section. CONSTITUTION: A suction brush(50) of a vacuum cleaner includes a brush body(51), a turbine(70) and a striking member(78). The brush body(51) has an upper housing(52) and a lower housing(53). A dirt suction port is formed at a bottom of the lower housing(53). A cavity is formed between the upper and lower housings(52,53) when the upper housing(52) is coupled to the lower housing(53). A connection part(60) is coupled to the lower housing(53) in order to connect the suction brush(50) to a vacuum cleaner body. The connection part(60) is communicated with the cavity. The connection part(60) forms a passage for dusts sucked through the dirt suction port.
