DUST COLLECTION FILTER FOR VACUUM CLEANER AND VACUUM CLEANER USING THIS FILTER
Document Type and Number:
Japanese Patent JP2521416
Kind Code:
B2
Abstract:
PURPOSE: To prevent breeding of a small vermin even when it escapes from a dust collection filter by fitting in a dust collection chamber a disposable bag-shape filter composed of a bag support member which is not treated by an expellant for the vermin and the like and a bag member, which is treated by the expellant, for receiving collected dust.
CONSTITUTION: A dust collection device is provided with a paper bag 10a, a paper bag support member 10a and the like of a dust collection filter 10. The paper bag 10a for collecting dust is subjected to an expellant treatment. Since contact frequency between a small vermin moving about in the paper bag 10a and the expellant is thereby increased, breeding of the small vermin is remarkably restrained and even when the small vermin escapes, it is killed within a short time. A portion of the paper bag support member 10b, which is directly touched by hands at the time of replacement of the dust collection filter 10, is not treated by the expellant. Operability of the filter 10 is thus enhanced.
