Abstract:
A filter mounting device for a vacuum cleaner which includes a casing having an open top portion and performing a primary dust collection in a cyclone mode, a cover for covering the open top portion of the casing, and a cylindrical filter engaged below the cover for performing a secondary dust collection by collecting fine dusts after the primary dust collection, comprising:a top surface of a filter which is detachably installed to a bottom surface of the cover, which is constructed to be rotatable by a predetermined angle in a mounted state, and which includes an engagement piece formed on one side of the periphery of the top surface such that a radial extension length thereof is gradually increased, and a coupling groove formed on the outside of the engagement piece; a support portion formed on the bottom surface of the cover for pivotably supporting the top surface of the filter mounted thereto by the predetermined angle; a movable member which is installed to be movable by a predetermined distance in a state where the movable member is in close contact with the bottom surface of the cover, and includes an engagement groove for closely receiving the engagement piece, a catching projection formed on one side of the engagement groove to be caught in the coupling groove and a confirmation piece formed to protrude beyond an opening formed in the rim portion of the cover at the opposite side of the engagement groove; and an elastic means for elastically supporting the movable member so that the confirmation piece can protrude through the opening, wherein when the top surface of the filter is rotated in a state where it is engaged to the support portion, the confirmation piece moves into the cover due to pushing of the engagement piece toward an inner surface of the movable member and the pushed state can be maintained by catch of the catching projection in the coupling groove.
