Beschreibung
Zusammenfassung:	The invention discloses an air inlet device. The air inlet device comprises a grating, an adjusting sliding chute and frames, wherein the adjusting sliding chute is fixed to the grating and parallel to the length direction of the grating, and the frames are located on the wide sides of the two sides of the grating and connected to the adjusting sliding chute, and can move on the adjusting sliding chute in the length direction of the grating. In the air inlet device, the gap L1 between the frames and the wide sides of the grating is adjusted by moving the frames in the adjusting sliding chute in the length direction of the grating, so that the whole length size of the air inlet device is changed, and uniformity of the gap L2 between the air inlet device and a dividing wall after the air inlet device is mounted is controlled. The length of the air inlet device can be adjusted, and therefore line marking and size cutting do not need to be conducted after the air inlet device is researched and mounted in situ for
