Dust collecting barrel of vacuum cleaner

Abstract

Disclosed a dust-collection barrel of vacuum dust collector comprises: a hollow barrel arranged on the mounting structure of dust-collection barrel which is depressed in the back of dust- collector, while said barrel has a upper hatch and a liquid inlet on its side surface; a cover which covers the upper open of said barrel with a exhaust outlet in its center; a filter inside the barrel and arranged under the cover to filter and collect the dust or foreign matters sucked by the liquid inlet; and a dust cleaner surround the outer periphery of filter and rotating via the airflow that flowing into the inner part of barrel to clean the dust on the outer periphery of filter. Said inventive dust-collection barrel has a dust cleaner surround the outer periphery of filter which can rotate too, therefore, driven by the air that flowing into the barrel, the dust cleaner rotates to clean the dust adhered on the outer periphery of filter to avoid the channel jam and the serious reduced suction.

Description

technical field [0001] The present invention relates to a vacuum cleaner. In particular, it relates to a dust collection barrel of a vacuum cleaner which can remove dust adhering to the filter itself, thereby preventing the dust from adhering to the filter and avoiding a sharp drop in suction. Background technique [0002] Generally, vacuum cleaners are classified into canister vacuum cleaners in which the vacuum cleaner is moved for cleaning and upright vacuum cleaners in which the body stands upright according to the form of the vacuum cleaner. [0003] Examples of canister vacuum cleaners are figure 1 with figure 2 shown, a brief description is given below. [0004] figure 1 is an oblique view of an existing vacuum cleaner structure; figure 2 It is an exploded oblique view of a part of the rear structure of a conventional vacuum cleaner. [0005] As shown in the figure, the existing canister vacuum cleaner includes a vacuum cleaner body 1 and a dust suction head 2...

AI Technical Summary

Problems solved by technology

[0014] However, when the canister vacuum cleaner of the prior art that cleans as described above is used for a certain period of time, fine dust will adhere to the outer peripheral surface of the filter 13 inside the bucket body 11 of the dust collecting bucket 6, thereby As a result, the suction force drops sharply. Therefore, the filter 13 must be cleaned or replaced periodically. However, when the vacuum cleaner is used in an area with a lot of dust and foreign matter, the filter 13 needs to be replaced or cleaned frequently, so it is inconvenient to use.
