Electric dust cleaner

Abstract

The invention relates to an electric vacuum cleaner, a rod 25 is hinged freely between the air suction opening 22 of the dust collection chamber 7 and the opening of the dust suction chamber 7, one end of the rod 25 is arranged at the flange of the opening of the dust collection chamber 7,simultaneously the other end of the dust collection chamber 7 is approximate to the air suction opening 22, the opening plate 6a of a dust collection bag 6 is arranged at the air suction opening 22 so as to revolve the rod 25, so that one end of the rod 25 is ejected in the dust collection chamber 7 to form an upright electric vacuum cleaner. When the dust collection bag is not arranged, the rod is arranged at the flange of the opening of the dust collection chamber, at the time the dust collection cover is incapable to be arranged, thereby preventing the mistaken use of electric vacuum cleaner positively, when the dust collection bag is intended to be replaced, one end of the rod is pressed, the other end of the rod moves upwardly to push the opening plate of the dust collection bag, thereby removing the dust collection bag easily so as to improve operation.

Description

【Technical Field】 [0001] The invention relates to an electric vacuum cleaner with a paper packaging bag inside. 【Background technique】 [0002] Conventionally, there is an electric vacuum cleaner containing a paper packaging bag in the dust collection chamber, as described in, for example, Japanese Patent Laid-Open No. 3-186238 (A47L 5 / 28). [0003] The upright electric vacuum cleaner has an air suction port connected with a hose formed on the back of the main body, that is, the inner side of the dust collection chamber, and the mouth plate of the paper packaging bag is pressed into the suction port for installation. [0004] In this configuration, since the paper packaging bag is larger than the mouth plate, it is difficult for the user to grasp the mouth plate when replacing the paper packaging bag filled with dust and trash and swells, and there is a disadvantage that the workability of replacing the paper packaging bag is poor. [0005] Furthermore, in the can-type electric v...

Problems solved by technology

[0007] Yet above-mentioned pulling-off operating tool is just the rod-shaped material that its two ends are in the position near the suction port both sides and the front is slightly in the shape of  shape, and the operating part in the middle is extended to the opening side of the dust collecting chamber and faces the It is only the opening, therefore, there is a case where the dust cover is installed without the dust bag installed

In this case, when starting the electric vacuum cleaner, there is a disadvantage that the attracted dust will be spread in the dust collection chamber.

In addition, when the paper packaging bag is unloaded with the above-mentioned pull-off operation tool, the relationship between the two ends of the upper part of the mouth plate is crimped with the pull-off operation tool, and the mouth plate is bent toward the suction port side, which hinders the smooth unloading of the paper package. The downside of the bag
