Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment design, and in particular to a vacuum cleaner. Background Technology

[0002] A vacuum cleaner is a common cleaning device used in homes, offices, hotels, and other similar places. A typical vacuum cleaner consists of a fan and a dust cup. The fan sucks up dirt and grime from floors or carpets, while the dust cup holds the dirt sucked up by the fan.

[0003] In modern vacuum cleaners, the dust cup often accumulates a lot of dust after prolonged use, affecting its usability. Furthermore, the fan and dust cup are usually fixed and cannot be separated. However, since the dust cup inevitably accumulates a lot of hard-to-remove dirt after long-term use, the non-removable design of the dust cup makes it difficult to clean and maintain the dust cup separately.
