The electronic valves of the first discharge pipe 152 and the second feeding pipe 153 are closed, and the booster pump 4 is further driven. Then, the air pressure enters the connecting pipe through the shunt pipe 62 on one side of the booster pump 4, and finally reaches the aerosol can 5 through the first feeding pipe 151. At this time, The aerosol can 5 can be subjected to a pressure test. After the test is completed, the water in one of the aerosol cans 5 needs to be discharged, and then the water can be discharged into the water storage tank 3 through the second discharge pipe 154. At the same time, the third electric telescopic rod 655 on one side is driven to make the fourth bevel gear 652 on this side mesh with the third bevel gear 642, and further drive the first motor to reverse, thereby driving the two ball valves 632 to rotate, so that one of the two ball valves is opened and the other is closed, and the above-mentioned pressure test operation can be repeated, thereby saving a certain amount of time and improving the working efficiency of the pressure test.
