Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a dust cup assembly for a vacuum cleaner. Background Art

[0002] At present, the dust bucket of a vacuum cleaner mainly includes a main body, a dust cup installed at the front of the main body, and a dust suction motor installed in the main body. The dust suction motor provides dust suction wind power into the dust cup. During operation, the dust cup sucks in sundries such as dust and garbage through the dust suction port. Large particle dust, garbage, etc. are filtered by the filter cylinder and directly stored in the outer dust cavity. After being used for a period of time, a lot of dust will adhere to the outer surface of the metal filter screen, which greatly affects the filtering efficiency of the metal filter screen. At this time, the cup cover must be opened to take out the metal filter screen for cleaning and then reinstalled for use. This not only brings inconvenience to the cleaning of the metal filter screen, but also requires cleaning the metal filter screen after a very short period of use, thus reducing the effective use time of the vacuum cleaner.
