The working principle is as follows: when the air door is closed, the door leaf I2 and the door leaf II 3 are combined in a rotating way, the second moving block 54 installed in the first rectangular groove 23 is firstly moved horizontally leftwards to the left side of the first L-shaped sliding groove 231, and then the second moving block 54 is moved downwards to enable the wind shield II 5 installed at the lower end of the door leaf I2 to move downwards and be abutted against the ground. The second step moves the second moving block 54 installed in the second rectangular groove 33 horizontally rightward to the right of the second L-shaped chute 331, and then moves the second moving block 54 downward to move the second wind deflector 5 installed at the lower end of the second door leaf 3 downward and close to the ground. Finally, the first moving block 43 is moved horizontally rightward along the first sliding groove 211, and the slide bar 42 is passed over the first clamping block 2111 to the rightmost end of the first sliding groove 211. The first wind shield and the second wind shield block gaps between the first door leaf and the second door leaf and the lower frame, so that cold air is prevented from being filled into a room from a door gap. When the air door is opened, the second moving block 54 installed in the first rectangular groove 23 is moved upward from the bottom of the first L-shaped chute 231, and then horizontally moved rightward and passes over the second clamping block 2311 to the right side of the first L-shaped chute 231. The second step moves the second moving block 54 installed in the second rectangular groove 33 upward from the bottom of the second L-shaped chute 331 and then horizontally leftward and beyond the third latch block 3311 to the left side of the second L-shaped chute 331. Finally, the first moving block 43 is moved horizontally leftward along the first sliding groove 211, and the sliding rod 42 is passed over the first clamping block 2111 to the leftmost end of the first sliding groove 211. Thus, the air door can be opened.

According to the utility model, the first wind shield and the second wind shield block the gap between the first door leaf and the second door leaf and the gap between the first door leaf and the lower frame, so that the problem of indoor temperature reduction caused by cold air filling into a room from a door gap is solved.
