[0001] The utility model relates to the technical field of pressure vessel detection equipment, in particular to a leakage detection device. Background Art

[0002] In the prior art, the method for testing the sealing between the through hole on the shell and the aluminum foil is to push a seal to seal the opening of the shell, then blow air into the shell, and stay for a period of time to detect whether the pressure value drops. If it drops, it means that the sealing is unqualified. However, the disadvantage of this detection method is that the opening of the shell is uneven, which will lead to poor sealing effect between the seal and the opening, affecting the detection result.
