The matching blocks 804 are elastically retracted inside the rotating rod 5. By providing the matching blocks 804, when the rotating rod 5 rotates following the main centrifugal blades 4, it can extend outward under the action of centrifugal force and come into contact with the inclined surface 803, squeezing the ring 802, so that the driving tooth 801 can move downward and stretch the elastic telescopic rod 8011; a plurality of groups of balls 8041 are movably installed on the side where the matching block 804 and the inclined surface 803 are in contact with each other, and the surface of the balls 8041 is in contact with the inclined surface 803.

The limit block is a prior art and is not shown in the figure. It can be optionally installed on the surface of the turntable 6 so that the auxiliary centrifugal blades 601 can change the opening direction and form a vortex in two directions of the gas to improve the efficiency of gas separation. Moreover, by setting a friction damping bearing, after the auxiliary centrifugal blades 601 are adjusted, only the mating teeth 805 rotate alone.

[0024] Combined with attachment Figure 1 -Attached Figure 8, and also includes a cleaning component 9 for vibrating and cleaning the auxiliary centrifugal blades 601, so that the auxiliary centrifugal blades 601 can intermittently knock on the inside of the auxiliary centrifugal blades 601 during the operation, so that the auxiliary centrifugal blades 601 vibrate and the dust falling on their surfaces falls off, thereby achieving the purpose of cleaning and ensuring that the auxiliary centrifugal blades 601 can work normally; it is worth noting that because the main centrifugal blades 4 are arranged directly below the air inlet 101 and are directly affected by the gas, a corresponding cleaning component 9 is not provided; the cleaning component 9 includes a driven rod 901 inserted into the inside of the connecting rod 806, and one end of the driven rod 901 penetrates the matching tooth 805 and extends to the inside of the circular groove 8051.

[0025] Specifically, when separating the gas, the gas is passed from the inside of the air inlet 101 into the inside of the centrifugal chamber 1 and acts on the surface of the main centrifugal blades 4, causing the main centrifugal blades 4 to rotate and driving the rotating rod 5 and the turntable 6 to rotate synchronously. When the flow rate of the gas increases, the rotation speed of the main centrifugal blades 4 will increase, causing the rotation speed of the rotating rod 5 to increase and increase the centrifugal force generated, causing the matching block 804 to begin to extend and come into contact and squeeze with the inclined surface 803, thereby driving the driving teeth 801 to move downward and come into contact with multiple groups of matching teeth 805, so that the matching teeth 805 that rotate with the turntable 6 begin to mesh with the driving teeth 801 and rotate, thereby driving the auxiliary centrifugal blades 601 to rotate synchronously, achieving the purpose of changing the opening direction, and changing the airflow inside the centrifugal chamber 1 from a unidirectional vortex state to a vortex in two different directions, thereby increasing the collision efficiency of particles in the gas and improving the gas separation efficiency; When the auxiliary centrifugal blade 601 completes the reversal, as the turntable 6 continues to rotate, the mating tooth 805 will rotate independently and begin to intermittently squeeze the cam 902 through the protrusion 8052, so that the cam 902 drives the support rod 903 installed on the surface of the driven rod 901 to start intermittent rotation, so that the ball 904 fixed at the end of the support rod 903 intermittently collides with the inner wall of the auxiliary centrifugal blade 601 and generates vibration, thereby achieving the purpose of cleaning.
