Method for cleaning dust filter, particularly vacuum cleaner, involves producing vibration in direction of rotational symmetry axis of vacuum cleaner and transferring vibration on vacuum cleaner

摘要

The method involves producing a vibration in direction of a rotational symmetry axis of vacuum cleaner (1) and transferring the vibration on a vacuum cleaner. The vibrations lie within ultrasonic range. The vibrations are produced by magnetic alternating field, within which a magnetic, particularly Ferro magnetic core is stored. Independent claims are also included for the following: (1) a device for cleaning a dust filter, particularly a vacuum cleaner; and (2) a dust filter, particularly a vacuum cleaner, which has a laminar element, particularly a fleece or a fabric, where the laminar element is made of paper or plastic.
