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.
Claims14
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-brushing 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.
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 and comprising:
- a dust-collecting main seat including a bottom wall, a dust-collecting main wall extending upwardly from an outer periphery of said bottom wall of said dust-collecting main seat, a first dust-collecting chamber, a dust-removing chamber spaced apart from said first dust-collecting chamber, and a vertical intake tube disposed fixedly within said dust-removing chamber and having a plurality of vent holes;
- a dust-brushing unit including a rotatable brush holder rotatable within said dust-removing chamber in 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 intake tube, 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 within said dust-collecting main seat;
- and
- a pre-separating seat disposed on and above said dust-collecting main seat and including a top wall, a surrounding wall extending from said top wall of said pre-separating seat toward said dust-collecting main wall of said dust-collecting main seat, a base wall disposed between said top wall of said pre-separating seat and said dust-collecting main seat and defining a top end of said first dust-collecting chamber, and a guiding chamber defined among said base wall, said surrounding wall of said pre-separating seat, and said top wall, said base wall being formed with a plurality of vent holes that are in fluid communication with both said first dust-collecting chamber and said guiding chamber and that are sized so as to permit passage of fine dust particles therethrough;
- wherein air flows from the intake port into the exhaust port along an airflow path including said first inlet in said dust-collecting main seat, said first dust-collecting chamber in said dust-collecting main seat, said vent holes in said base wall of said pre-separating seat, said guiding chamber in said pre-separating seat, said dust-removing chamber in said dust-collecting main seat, and said vent holes in said intake tube of said dust-collecting main seat.
