s1: the vertical rod (1) is installed outdoors, air is sent into the vertical rod (1) through the air inlet (101) by external wind, the first guide pipe (1011) is arranged at the position, where the air inlet (101) is arranged, of the inner wall of the vertical rod (1), the air entering the vertical rod (1) can be prevented from being directly discharged out of the vertical rod (1) through the air inlet (101) at the other side, the driving motor (2) is controlled to operate, the output end of the driving motor (2) drives the fan blades (202) to rotate through the rotating shaft (201), and then the air entering the vertical rod (1) moves towards the upper side of the vertical rod (1);

s2: air moving to the upper side of the upright rod (1) is abutted against the conical baffle (3) to enable the rising air to collide with the curved surface of the conical baffle (3) so as to enable the air at the upper side and the air at the lower side to be primarily mixed, the mixed air enters the movable groove (102) along the curved surface of the conical baffle (3) and continues rising, the mixed air rises to pass through the air outlet (103) and enters the mixing box (5) through the hose (7), and the mixing box (5) mixes the mixed air again;

s3: a driving gear (2011) on the rotating shaft (201) is meshed with a driven gear (141) on the first rotating rod (14), the first rotating rod (14) and the rotating shaft (201) reversely rotate, a main bevel gear (142) at the end part of the first rotating rod (14) is meshed with a secondary bevel gear (112) on the sleeve (11), the sleeve (11) and a first eccentric wheel (111) fixedly arranged on the outer side of the sleeve (11) rotate, meanwhile, a second rotating rod (15) synchronously rotates along with the rotating shaft (201) under the action of a synchronizing wheel (16) and a belt (161), a first bevel gear (1511) on the second rotating rod (15) is meshed with a second bevel gear (1512) on the rotating rod (12), the rotating rod (12) drives a second eccentric wheel (121) to rotate, and when the first eccentric wheel (111) and the second eccentric wheel (121) rotate, the mixing box (5) is driven to reciprocate up and down, mixing the air primarily mixed inside again;

s4: when the sleeve (11) and the rotating rod (12) rotate reversely, the first blade (113) on the sleeve (11) and the second blade (124) connected with the rotating rod (12) rotate oppositely, so that air in the mixing box (5) forms turbulent flow and is mixed;

s5: when the sleeve (11) rotates, the pinion (8) on the outer side is meshed with the large gear (9) in the mixing box (5), the large gear (9) drives the toothed turntable (10) to rotate, the toothed turntable (10) is intermittently and repeatedly meshed with the rack plate (182) when rotating, the rack plate (182) drives the connecting plate (181) to move, the moving rod (183) drives the partition plate (184) to move left and right, the intermittent plugging is carried out on the intersection of the second threaded pipe (702) and the mixing box (5), the sleeve (11) rotates for multiple times when the partition plate (184) plugs the second threaded pipe (702) and the mixing box (5), so that the air in the mixing box (5) realizes multiple vertical mixing and shaking periods, when the partition plate (184) does not plug the second threaded pipe (702) and the mixing box (5), the mixed air enters the detection channel (6) through the second threaded pipe (702), and the air pollution is monitored and early warned through a sensor (601) in the channel.
