Abstract
A dust collection device has a tank, a suction unit, a filtering unit, a dust removal unit, a first detection unit, and a control unit. The tank has an air inlet for accommodating dust. The suction unit aspirates the dust through the air inlet. The filtering unit captures the dust through the air inlet. The dust removal unit removes the dust from the filtering unit. The first detection unit detects an operational state of the suction unit. The control unit controls the suction unit and the dust removal unit. The control unit activates the dust removal unit, when the first detection unit detects that the suction unit operates for a first predetermined time period and then stops operating.
