Description

Technical Field

[0001] The utility model relates to the technical field of dust cups for vacuum cleaners, in particular to a cyclone dust cup for vacuum cleaners. Background Art

[0002] Household vacuum cleaners, dust mite removers and other dust collection equipment generally have a dust cup assembly for filtering. Most of the existing air dust collection and filtration are completed in a dust cup, and dust can easily cause the filter element to be blocked. Taking the Chinese utility model with application number CN202022328379.2 as an example, it discloses an easy-to-clean dust mite remover, including a dust head component, a suction generating chamber, a docking chamber and a dust-gas separation device, and the dust-gas separation device is detachably embedded above the dust head component and extends to the top of the docking chamber. The overall structure of this structure is relatively simple, but because the handheld dust mite remover sometimes needs to be used inverted, and the traditional dust mite remover will cause dust reflux and blockage once it is used inverted, which seriously affects the normal use of the dust mite remover and may even cause the internal motor to be overloaded and damaged. In addition, the dust cups of the existing dust mite removers are mostly arranged vertically, and the dust collection effect is achieved by using the gravity of the sucked dust. This method will limit the structure of the main body itself and also limit the use of the dust mite remover and the vacuum cleaner at different angles. Utility Model Content
