Automatic dust scraping device and dust collector

Abstract

The invention discloses an automatic dust scraping device and a dust collector. The automatic dust scraping device comprises a support assembly which is arranged in a dust cup of the dust collector; and a dust scraping assembly arranged in the support assembly, wherein the dust scraping assembly is rotationally connected with the support assembly, and the dust scraping assembly is arranged on the periphery of a filtering device of the dust collector in a sleeving mode; and the dust scraping assembly is used for cleaning the surface of the filtering device by rotating when the dust collector works, so that attachments on the surface of the filtering device are collected into the dust cup. When the dust collector works, the dust scraping assembly can rotate and sweep the surface of the filtering device, so that the situation that the dust collection effect of the dust collector is affected due to the fact that garbage blocks the outer surface of the filtering device is avoided, the dust cup of the dust collector can be prevented from being frequently taken down to clean the filtering device, and the use of the dust collector is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to an automatic dust scraping device and a vacuum cleaner. Background technique [0002] The main structure of the handheld vacuum cleaner has a filter device. When the vacuum cleaner is working, a negative pressure is formed in the main structure of the vacuum cleaner, and air is sucked from the opening of the dust cup of the vacuum cleaner while dust and other garbage are brought into the dust cup, and then The air flows into the main body of the vacuum cleaner through the filter device, and the garbage is blocked in the inner cavity of the dust cup by the filter device. At present, the way to dispose of the garbage in the dust cup is to separate the dust cup from the main body of the vacuum cleaner after the vacuum cleaner has been used for a period of time, and then pour out the garbage in the dust cup. However, when the vacuum cleaner is working, it is inevitable that t...
