For example, the second air outlet column 20 has an initial position, and the second air outlet column 20 also has a second position in the outflow direction of the airflow flowing out of the first air outlet 11, so as to block the first air outlet 11 and prevent the first air outlet from Air port 11 blows straight. Also for example, the second air outlet column 20 has an initial position, and the second air outlet column 20 also has a third position between the first air outlet 11 and the user's position, so as to block the first air outlet 11 and prevent the first air outlet from The airflow blown out by the air outlet 11 blows directly on the person at the user's position, and the user's position can be further detected through human sensing, and then the second air outlet column 20 is controlled to move between the user's position and the first air outlet 11 .

In some embodiments of the present utility model, the second air outlet column 20 has an initial position, and the second air outlet column 20 also has a fourth position. At the fourth position, the second air outlet 21 can be rotated to align with the first air outlet. The position of the first air inlet 13 , or the second air outlet post 20 also has a fifth position, and at the fifth position, the second air inlet 23 can be rotated to align with the first air outlet 11 .

Further, the second air outlet column 20 can be moved to the above-mentioned initial position, the second position, the third position, the fourth position, and the fifth position, and of course it can also be moved to other positions other than these five positions, so as to realize various Blow the air. Further, the line connecting the two ends of the preset track is collinear with the two diagonal lines of the first air outlet column 10; or, the two ends of the preset track are connected to circle the first air outlet column 10, as A circular shape coaxial with the rotation axis of the heat exchange fan.
