[0002] The fresh air fan is an effective air purification device that can circulate indoor air. On the one hand, it discharges the polluted air indoors to the outside, and on the other hand, it inputs the fresh air outdoors into the room after sterilization, disinfection, filtration and other measures.

[0003] An existing Chinese utility model patent with reference publication number CN213273024U discloses a high-pressure humidification device for fresh air, comprising a fresh air blower, a water pipe bend fixedly mounted on the right side of the high-pressure humidifier of the fresh air blower, an air supply pipe fixedly mounted on the right side of the fresh air blower's exhaust port, an exhaust box fixedly mounted on the right side of the air supply pipe, an open lower side of the exhaust box, a through hole formed on the upper side of the exhaust box, the right side of the water pipe bend inserted into the through hole, an atomizing nozzle mounted on the lower end of the water pipe bend, and an adjustment device mounted on the lower side of the exhaust box. The adjustment device includes an electric push rod fixedly mounted on the right side of the exhaust box, a connecting rod fixedly mounted on the left side of the telescopic rod of the electric push rod, a lifting plate fixedly mounted on the left side of the connecting rod, and a sealing ring fixedly mounted on the lower side of the exhaust box, which is tightly fitted with the lifting plate.
