Further, adjustment mechanism has seted up a plurality of through-holes including rolling disc, through-hole, fixed axle, erection column and air duct on the rolling disc, and the through-hole distributes on the rolling disc annularly, rolling disc upper end fixedly connected with fixed axle, rolling disc lower extreme fixedly connected with erection column, the erection column rotates with the base to be connected, erection column and step motor's power output shaft fixed connection, the fixed axle rotates with the casing to be connected, all fixedly connected with air duct in every through-hole.

Further, still including first sealing washer, the base upside all fixedly connected with first sealing washer with the inside upside of casing.

Further, still including the second sealing washer, the base upside all fixedly connected with second sealing washer with the inside upside of casing.

Further, the device also comprises a bolt, and the first lug plate and the second lug plate are matched with the bolt.

Furthermore, the diameters of the inner holes of the air guide tubes are different.

According to the invention, the diameters of the inner holes of the air guide pipes are different, so that gases with different flow rates can be discharged; simultaneously, through the stepping motor, accurate adjustment can be realized.
