Title:
DUST COLLECTING FILTER FOR VACUUM CLEANER
Document Type and Number:
Japanese Patent JP2501262
Kind Code:
B2
Abstract:
PURPOSE: To prevent the scattering of dust in a bag to the outside from the dust suction hole of a mouth plate provided in a vacuum cleaner when a dust collecting filter is pulled out from a dust collecting chamber opening by covering the dust suction hole provided on the mouth plate with a blocking lid part in the state where the mouth plate is mounted on the dust collecting chamber opening.
CONSTITUTION: When a dust collecting filter 19 is used while the dust removal of the dust collecting filter 19 is timely repeated, the dust collecting filter 19 is filled with dust without leaving an excessive space. In such a time, the dust collecting filter 19 filled with the dust is removed from a dust case 2, and a new dust collecting filter 19 is mounted. Namely, the removal of the dust collecting filter 19 is carried out by operating a cramp 46 to open a dust case lid body 43, and closing a dust suction hole 67 with the blocking lid body 68 of the dust collecting filter 19. Thereafter, a mouth plate 66 is held to pull the dust collecting filter 19 to the outside, whereby a filter support plate 36 is opened, and the dust collecting filter 19 can be pulled out of the dust case 2. Since the dust suction hole 67 is closed by the blocking lid body 68, the dust is never dropped from the suction hole 67.
