Electric vacuum cleaner

Abstract

The invention provides a vacuum cleaner which can not only prevent the dust collecting bag from being started by mistake, but also make the dust collecting bag easy to assemble and disassemble. A dust collecting bag (9) with a sack coaming plate (8) and a machine cover (6) covering the top of the dust collecting chamber in a rotatable manner. The dust bag detection body (12) is provided on the machine cover, and the dust collection bag detection body is provided with: a raised part (12A) to prevent the machine cover from entering the closed state when the dust collection bag is not installed in the dust collection chamber, and A detection part (12B) for detecting that the dust bag has been loaded into the dust chamber. When the detecting part detects that the dust collecting bag has been loaded into the dust collecting chamber, the protruding part is displaced to a position where the machine cover enters a closed state. In this way, not only can prevent the machine cover from being closed by mistake when the dust bag is not installed, but also, the assembly and disassembly of the dust bag can be carried out by only one action, and the assembly and disassembly will become easy.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner which can facilitate loading and unloading operations of a dust collecting bag in a dust collecting chamber. Background technique [0002] In the existing electric vacuum cleaner, the front portion of the vacuum cleaner body is provided with an air suction port, and the vacuum cleaner body is provided with a dust collecting chamber and an electric blower housing chamber in which the electric blower is housed. In the above-mentioned dust-collecting chambers, some are provided with a flange on the bottom surface of the dust-collecting chamber, and some are provided with a flange for fixing the pocket opening from the bottom surface of the dust-collecting chamber to the height near the opening of the dust-collecting chamber. The box-shaped flanges on the left and right sides of the dust collection bag are temporarily fixed in the dust chamber through such a structure, and then the upper part of t...

AI Technical Summary

Problems solved by technology

When viewed from above, the positioning flange and the suction port used to determine the position of the dust bag will be blocked by the pressing part of the bag opening panel and it is difficult to see, so the user can only install the dust bag by feeling, which is prone to accidents. Insertion errors, misalignment of the suction hole and the suction port, etc., may cause dust leakage, failure of the electric fan or even failure of the electric vacuum cleaner itself

In addition, when the dust is full and the dust bag needs to be taken out, the pressing part of the bag mouth panel may hook the suction hole, which is not only difficult to take out, but also may cause the dust in the dust bag to spill, which is harmful to the user. cause unreliable work

Moreover, the dust spilled into the dust collection chamber may also directly invade the electric fan, causing the electric vacuum cleaner to malfunction.
