Then, opening a second electromagnetic valve, a sixth electromagnetic valve, a third electromagnetic valve and a fifth electromagnetic valve, vacuumizing the tank A, and filling the tank B;
s6, when the weight of the tank B measured by the weighing device reaches a weight threshold value, the buzzer alarms, the second electromagnetic valve, the sixth electromagnetic valve, the third electromagnetic valve and the fifth electromagnetic valve are closed, the valve at the opening of the tank B is closed, and then the first electromagnetic valve and the second electromagnetic valve are opened for recovery processing;
s7, when the preset recovery time is up, removing the tank B, replacing the tank B with a new tank to be filled, and closing the first electromagnetic valve and the second electromagnetic valve; and then circularly operating according to the steps.
