[0040] A specific application of this embodiment is:

[0041] The first step: when using, first place the air duct at the designated position. When the air duct needs to be spliced ​​for use, pull the adjusting cap 11, and the adjusting cap 11 drives the limiting rod 8 to move. After the limiting rod 8 moves, the spring 10 is squeezed, and then the splicing plate 3 is inserted into the splicing groove 6. After the splicing plate 3 is inserted into the splicing groove 6, loosen the adjusting cap 11, so that the spring 10 is released by the force, so that the spring 10 drives the limiting rod 8 to insert into the slide groove 4, so that the air duct can be spliced ​​for use;

[0042] Step 2: When the air volume of the air duct needs to be adjusted, the electric telescopic rod 16 is started, and the electric telescopic rod 16 drives the C-shaped block 2 17 to move. After the C-shaped block 2 17 moves, it drives the adjustment block 19 to rotate on the rotating shaft 2 18, so that the adjustment block 19 can drive the C-shaped block 3 21 to move. After the C-shaped block 3 21 moves, it drives the C-shaped block 1 14 to move, so that the C-shaped block 1 14 can drive the shutter fan 13 to rotate, and the shutter fan 13 is adjusted to a suitable position according to the needs, so as to complete the work of adjusting the air volume of the air duct;

[0043] Step 3: When the air duct is in use, the filter 23 filters impurities in the air. When wind enters the air duct 1, the spring 25 is subjected to the pressure of the wind, thereby driving the filter 23 to move. Since the wind pressure varies in size, the spring 25 drives the filter 23 to shake. Under the action of shaking, the filter 23 can clean the impurities adsorbed on the filter 23, thereby preventing the occurrence of excessive adsorption of impurities on the filter 23.
