electric vacuum cleaner

Abstract

To provide an electric vacuum cleaner capable of capturing fine dust and improving dust collection performance with an inexpensive structure and an integral secondary filter. The electric vacuum cleaner has: a dust collection container, which is installed on the main body of the vacuum cleaner; a primary filter body, which is installed on the dust collection container and has a primary filter; The filter body is provided with a support body supporting a movable bag-shaped secondary filter, and the blocking end of the secondary filter is folded back to the inside of the support body, and the secondary filter body is installed on the primary When the filter body is used, the protrusion of the central part of the primary filter body is inserted into the inner side of the support body, wherein a bottom rib is formed at the bottom of the primary filter body, and the upper edge of the bottom rib is located at the lower end of the primary filter body. The lower edge of the lower floor window portion is near the position of the upper side.
