10. A control method for an outdoor air purification device with adaptive wind direction according to any one of claims 1 to 9, characterized in that: The following steps are involved: S10: Collect and record monitoring data, and calculate the theoretical direction of the air purification module according to the monitoring data; S20: If the difference between the actual orientation and the theoretical orientation exceeds the error range, the central controller sends a control command to the electric travel wheel; S30: Calculate the theoretical maximum wind speed of the air purification module when the active fan module is not working. If the theoretical maximum wind speed exceeds the optimal wind speed range of the air purification module, the central controller sends a diversion adjustment control instruction to the electric track wheel of the guide plate and the telescopic electric screw to adjust the active diversion module to the optimal angle corresponding to the optimal wind speed range of the air purification module and the optimal length of the telescopic guide plate; If the theoretical maximum wind speed is within the optimal wind speed range of the air purification module, the central controller sends a diversion adjustment control instruction to the electric track wheel of the deflector plate and the telescopic electric screw to adjust the movable deflector module to the optimal angle corresponding to the theoretical maximum wind speed of the air purification module and the optimal length of the telescopic deflector when the movable fan module is not working; If the theoretical maximum wind speed is lower than the optimal wind speed range of the air purification module, the central controller sends a guide adjustment control command to the guide plate electric track wheel, the telescopic electric screw and the fan adjustment control command to the axial flow fan and the fan electric track wheel to adjust the movable guide module to the maximum angle and the maximum length of the telescopic guide plate, move the movable fan module to the rear of the air purification module, and start the axial flow fan; S40: Calculate the actual purification rate. If the actual purification rate is lower than the theoretical purification rate, send a warning of equipment purification failure to the alarm display screen; Calculate whether the equipment is blocked. If the monitoring data is lower than the theoretical wind speed, send a device blockage warning to the alarm display screen; S50: Enter the next cycle S10.
