Specifically, the negative pressure device 10 is used to provide negative pressure to the cyclone 20 to form cyclone in the cyclone separating apparatus 100 to separate gas and dust.

Referring to fig. 3, the negative pressure device 10 includes an air inlet 11, at least two cyclones 20 are disposed outside the negative pressure device 10, each cyclone 20 includes a suction opening 21 and an exhaust opening 22, and the exhaust openings 22 are in fluid communication with the air inlet 11. Specifically, the airflow containing the dust enters the air inlet 11 through the suction opening 21 and the exhaust opening 22 of the cyclone 20 via the negative pressure device 10, and the dust is discharged from the dust discharge opening 23 of the cyclone 20.

Wherein, the distance from each pumping hole 21 to the gas inlet 11 along the gas flowing direction is equal.

Thus, since the distances between the air extraction opening 21 of each cyclone 20 and the air inlet 11 are equal in the airflow flowing direction, the air extraction pressures distributed from the air inlet 11 to the air extraction openings 21 are the same, so that the airflow containing dust can be uniformly distributed to the air extraction openings 21, and when at least two cyclones 20 share one dust collection chamber, cross air leakage or interference phenomenon is not generated at the dust discharge opening 23, and the separation effect of the cyclone separation device 100 is good.
