Title:
VACUUM CLEANER AND SEPARATION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/103688
Kind Code:
A1
Abstract:
A vacuum cleaner and a separation mechanism (10). The separation mechanism (10) comprises cyclone separators (200) and a dust collecting component (100); each cyclone separator (200) comprises a cyclone unit (230); a dust discharge port (220) of each cyclone unit (230) is communicated with a dust collecting cavity (110) of the dust collecting component (100); at least two air inlet cavities (120) are arranged around a first axis (a); the number of the cyclone separators (200) is the same as that of the air inlet cavities (120); an air inlet (210) of the cyclone unit (230) of each cyclone separator (200) is communicated with the corresponding air inlet cavity (120). Dusty gas flows around the first axis (a); the at least two air inlet cavities (120) can effectively separate the dusty gas in different air inlet cavities (120); the dusty gas in each air inlet cavity (120) can be separated by the corresponding cyclone separator (200), and the dusty gas imbalance entering each cyclone separator (200) can be effectively reduced, so that the gas-dust separation efficiency of the cyclone separators (200) can be improved. Moreover, the gas-dust separation efficiency can be effectively improved by configuring the at least two cyclone separators (200).
