Optionally, the method for controlling a fresh air device further comprises: and under the condition that the fresh air equipment is determined to be started for the first time on the current date, the water mist generation module 100 is controlled to be closed, and the water supply module 200 executes a water changing instruction of the water tank 210. Like this, in some new trend equipment's model, water supply module 200's water tank 210 is open design, takes place the filter effect of module 100 to the air in order to guarantee water smoke to prevent when new trend equipment does not start, the dirt in the deposit air in the water tank 210, consequently, control new trend equipment when opening for the first time every day, control water supply module 200 earlier and carry out water tank 210 and trade the water instruction. Because the water tank 210 can influence the work of the water mist generation module 100 in the water changing process, the water mist generation module 100 is controlled to be closed while the water tank 210 water changing instruction is executed, and after the water tank 210 water changing is finished, the water mist generation module 100 is controlled to operate according to the air quality information of the outdoor environment.

Optionally, under the condition that the concentration of the carbon dioxide gas in the associated area of the fresh air equipment is determined to be beyond the reference concentration range, the fresh air equipment is controlled to be started and whether the fresh air equipment is started for the first time on the current date is judged; if the fresh air equipment is started for the first time on the current date, the water mist generation module 100 is controlled to keep a closed state, and the water supply module 200 is controlled to execute a water changing instruction of the water tank 210; if the fresh air equipment is not started for the first time on the current date, the air quality information of the outdoor environment is obtained, and the operation condition of the water mist generation module 100 is determined according to the air quality information of the outdoor environment.
