[0023] The specific implementation process of the utility model is as follows: when in use, when it is necessary to mix the special gas, first start the lower air pump 5, the lower air pump 5 extracts the gas inside the gas storage tank 2 through the air intake pipe 6, and the gas is discharged into the connection tank 10 through the air outlet pipe 7. After the gas is injected into the connection tank 10, the movable plate 88 moves up under the action of air pressure. When the upper end contact switch of the movable plate 88 contacts the baffle 83, the lower air pump 5 stops working at the same time, and then starts the upper air pump 13, the upper air pump 13 extracts the gas inside the connection tank 10 through the air intake pipe 14, and the gas is finally discharged into the mixing tank 17 through the exhaust pipe 15 for mixing the special gas.

When the adjustment is completed, the plug block 92 is reset and inserted into the slot 91 at another position. The screw 81 can be limited by the connection between the plug block 92 and the slot 91 to prevent the screw 81 from rotating, thereby preventing the baffle 83 from moving in the vertical direction, so that the position of the baffle 83 remains fixed. Even if the internal air pressure of the connecting tank 10 is relatively high, the screw 81 will not rotate under pressure, thereby improving the control accuracy of the exhaust volume.
