Dust collector for a vacuum cleaner
First Claim
1. A dust collector for a vacuum cleaner, the vacuum cleaner having a cleaner body that is formed with an intake port and an exhaust port, said dust collector being adapted to be disposed within the cleaner body between the intake port and exhaust port and comprising:
- a dust-collecting main seat including a first dust-collecting chamber that has an upper end opening, and a first inlet that is adapted to be disposed between and to be in fluid communication with the intake port in the cleaner body and said first dust-collecting chamber;
a mounting seat connected removably to said dust-collecting main seat and disposed within said upper end opening of said first dust-collecting chamber, said mounting seat including a bottom plate, and an intake tube projecting downwardly from said bottom plate and having a plurality of vent holes; and
a dust-bushing unit including a rotatable brush holder rotatable relative to said dust-collecting main seat in response to flow of air from the intake port in the cleaner body into the exhaust port in the cleaner, a dust-collecting net covering said vent holes in said mounting seat, and a plurality of dust brushes attached to said rotatable brush holder and brushing said dust-collecting net so as to remove dust from said dust-collecting net when said rotatable brush holder rotates relative to said dust-collecting main seat;
whereby, when sucked into the intake port in the cleaner body, air flows from the intake port into the exhaust port, and therefore rotates said rotatable brush holder relative to said dust-collecting main seat so as to remove dust from said dust-collecting net by said dust brushes;
wherein said mounting seat further includes a wheel chamber disposed directly above said intake tube, said dust-brushing unit further including a vane wheel disposed rotatably within said wheel chamber in said mounting seat and connected to said rotatable brush holder so as to allow for synchronous rotation of said vane wheel and said rotatable brush holder when air flows from the intake port into the exhaust port;
wherein said mounting seat further includes a mounting plate disposed above said bottom plate and defining said wheel chamber, and a wind-guiding chamber disposed between said bottom plate and said mounting plate and having a wind-guiding outlet that guides air from said intake tube into said wheel chamber.

Abstract
A dust collector is disposed between an intake port and an exhaust port in a vacuum cleaner. Air flows from the intake port into the exhaust port along an airflow path in the dust collector. The dust collector includes a dust-collecting net disposed in the path, and a dust-brushing unit. When air flows from the intake port into the exhaust port, a plurality of dust brushes of the dust-brushing unit rotate to brush the net so as to remove dust from the net. Therefore, air can flow unimpeded through the net.
