Title:
CYCLONE SEPARATOR AND VACUUM CLEANER
Document Type and Number:
WIPO Patent Application WO/2021/056869
Kind Code:
A1
Abstract:
A cyclone separator (100) and a vacuum cleaner provided with same. The cyclone separator (100) comprises an air inlet channel (216), a first separation channel (61), a second separation channel (25), and an air discharging channel (412). The first separation channel (61), the second separation channel (25), the air discharging channel (412), and the air inlet channel (216) are coaxially provided sequentially from outside to inside. The air inlet channel (216), the first separation channel (61), the second separation channel (25), and the air discharging channel (412) sequentially communicate end to end with each other. An end of the air inlet channel (216) not connected to the first separation channel (61) communicates with an external environment. An end of the air discharging channel (412) not connected to the second separation channel (25) communicates with an external environment. An airflow entering the cyclone separator (100) is twice subjected to separation by means the first separation channel (61) and the second separation channel (25), thereby achieving a good separation effect. In addition, since the first separation channel (61) and the second separation channel (25) are coaxial, and communicate end to end with each other, the cyclone separator (100) has a compact and simple structure, and occupies less space inside a vacuum cleaner, thereby allowing a vacuum cleaner to be small.
