Wherein, the driving structure 40 is in driving connection with the winding structure 70 to drive the winding structure 70 to rotate around the pivot axis, so as to wind the wet film in the liquid storage structure 32. Thus, when the humidifying structure 31 needs to be switched between the humidifying state and the avoiding state, the driving structure 40 is started, the driving structure 40 drives the winding structure 70 to move, so that the winding structure 70 drives the first side edge of the wet film to move, and the wet film is wound on the winding structure 70, and the winding movement of the humidifying structure 31 is easier and simpler.
Specifically, when the ventilation and humidification device is required to only supply fresh air, the driving structure 40 is started to enable the winding structure 70 to drive the first side edge of the wet film to move, so that the wet film is wound on the winding structure 70 until the wet film is in an avoiding state, outdoor fresh air is directly blown into a room through the air outlet 11 after entering the fan 20, and the outdoor fresh air cannot pass through the humidification assembly 30. When the ventilation and humidification device is needed to humidify outdoor fresh air, the driving structure 40 is started, the winding structure 70 rotates reversely to reduce the winding force between the winding structure 70 and the wet film, the wet film is convenient to wind down from the winding structure 70, the second side edge of the wet film is unfolded under the action of self weight or under the dragging of workers until the wet film seals the air outlet 11 and is in a humidification state, and the outdoor fresh air enters the fan 20 and is blown indoors after being humidified by the humidification component 30.
