When the plate 18 moves, the first automatic winding shaft 16 is automatically wound and extended with the movement of the wind shield 17. When the volatilization area of ​​the volatile cotton plate 6 is adjusted, the limiting slide plate 24 moves synchronously with the sliding plate 18. When the volatilization area of ​​the volatile cotton plate 6 is reduced, the distance between the two limiting slide plates 24 is synchronously reduced, so that the movement distance of the sliding cross bar 29 is increased. The air volume passing through the ventilation slot 25 is adjusted by adjusting the distance between the sliding cross bars 29, and the minimum distance between the two sliding cross bars 29 shall not be less than the distance between the two limiting slide plates 24 to ensure that when the volatilization area of ​​the volatile cotton plate 6 is reduced, there is still suitable air blowing through the volatile cotton plate 6. When the volatilization area of ​​the volatile cotton plate 6 needs to be increased, it is necessary to first increase the distance between the two sliding cross bars 29 to increase the air volume, and then increase the volatilization area of ​​the volatile cotton plate 6 to prevent the air volume from being too small and reducing the volatilization effect of the fragrance essential oil.
