Claim 1:
2. The window-mounted smart air purifier according to claim 1, the window-mounted smart air purifier further comprises a spring damper that is installed in the outdoor air suction opening,
wherein the spring damper opens the outdoor air suction opening when air circulates, and closes down the outdoor air suction opening when air stop circulating,
wherein when the controller determines that there are problems in the outdoor air that are detected by the VOC sensor, and stops an operation of the second air circulation unit, the spring damper closes down the outdoor air suction opening by its own elastic force, and
when the controller determines that there is no issue in the outdoor air that is detected by the VOC sensor, and allows an operation of the second air circulation unit, a force generated by the air circulation forcibly opens the outdoor air suction opening.
