Electric vacuum cleaner

Abstract

An object of the present invention is to provide an electric vacuum cleaner capable of providing high usability in opening and closing a dust collection chamber cover. The electric vacuum cleaner of the present invention comprises: an electric blower fan (2) for attracting dust; a dust collection chamber (3) for collecting the inhaled dust; A dust chamber; a main body (1) with an electric blower inside; and a freely rotatable moving wheel (4) that acts as a running device for the main body. Wherein, the rotation center of the dust collection chamber cover is the same as the rotation center of the moving wheel; when the dust collection chamber cover covers the dust collection chamber, the front end part of the front part of the dust collection chamber cover is located above the rotation center of the dust collection chamber cover . In this way, when the dust collection chamber cover is about to be closed, the dust collection chamber cover will not have a strong momentum, so the problem of causing a strong impact on the main body can be solved, thereby providing a new method for opening and closing the dust collection chamber cover. An electric vacuum cleaner with high usability during closing.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner used in common households, and more particularly relates to the improvement of the performance of its dust collecting parts. Background technique [0002] First describe the existing electric vacuum cleaner below. [0003] like Figure 14 As shown in , the existing electric vacuum cleaner includes: an electric fan 12 for attracting dust; a dust collection chamber 13 which is connected with the suction head for attracting dust; a main body 15; and a dust chamber cover 16 for covering the dust chamber 13 (for an example thereof, refer to Japanese Patent Laid-Open No. 1-314529). [0004] In addition, in Figure 15 The existing electric vacuum cleaner shown in is provided with: a dust collection chamber 13 that communicates with the suction head that attracts dust and is used to catch dust; a main body 15 with moving wheels 14 hidden in the rear bottom; 13, an electric fan 12 for attracting dus...

AI Technical Summary

Problems solved by technology

[0006] But in the structure of above-mentioned existing electric vacuum cleaner, because the rotation center of described dust collection chamber cover 16 is as Figure 14 As shown in , it is roughly located on the upper part of the main body 15. Therefore, when the dust bag cover 16 is opened to replace the dust bag, if the dust bag cover 16 is accidentally touched , or under the action of heavy objects such as dust suction pipes installed on the dust collection chamber cover 16, the dust collection chamber cover 16 may be slammed shut

At this time, since the rotation center of the dust collection chamber cover 16 is approximately at the upper part of the main body 15, when the dust collection chamber cover 16 is closed, the front end of the dust collection chamber cover 16 is mostly at a height lower than the rotation center. Therefore, when the dust collection chamber cover 16 is about to be closed, the dust collection chamber cover 16 has considerable kinetic energy, and there is a problem that it will cause considerable impact to the main body 15.

[0007] In addition, if Figure 15 As shown in , the dust collection chamber cover 16 rotates around the center of the moving wheel 14, although the front end of the dust collection chamber cover 16 may be at a height higher than the center of rotation when the dust collection chamber cover 16 is closed However, since the electric fan 12 is located inside the dust chamber cover 16, if the weight of the electric fan 12 is added, the dust chamber cover 16 also has a considerable weight when it is about to be closed. Kinetic energy, so there is also the problem of causing considerable impact on the main body 15
