Document Type and Number:
WIPO Patent Application WO/2023/021733
Kind Code:
A1
Abstract:
This collection device is configured to collect dust from a vacuum cleaner having a filter unit and a dust storage chamber, the collection device comprising a dust flow path, a suction source, and a control unit. The control unit sequentially executes: first suction control whereby the suction force of the suction source is controlled so as to cause at least a portion of the dust captured in the filter unit to flow into the dust flow path; second suction control whereby the suction force of the suction source is decreased to change a deformation state of the filter unit caused by the suction force, thereby changing the clogged state of dust clogged in the mesh of the filter unit; and third suction control whereby the suction force of the suction source is increased to cause at least a portion of the dust for which the clogged state in the mesh was changed to flow into the dust flow path.
