[0020] The clamping mechanism includes a cylinder 9, the output end of the cylinder 9 is fixedly connected with a clamp 10, the clamp 10 corresponds to the filter element installation port 4, and the outer walls opposite to the clamp 10 and the filter element installation port 4 are provided with sealing rings 5. The two sealing rings 5 ​​are respectively tightly fitted with the outer walls at both ends of the filter element to form a good soft seal.

[0021] The clamping mechanism also includes a plurality of fixing rods 7 fixedly connected to the outer wall of one side of the sealing chamber 1, and the ends of the plurality of fixing rods 7 away from the sealing chamber 1 are fixedly connected to a mounting plate 8, a cylinder 9 is fixedly mounted on the outer wall of the mounting plate 8 away from the sealing chamber 1, and the output end of the cylinder 9 passes through the mounting plate 8.

[0023] The control module 12 has a built-in data processing unit, which is used to receive the signal from the air pressure sensor 13 and process it to obtain the leakage detection result of the filter element.

[0024] The implementation principle of a filter element leak detection device in the embodiment of the present application is as follows: when in use, firstly, the end of the filter element to be detected is sleeved on the filter element installation port 4, and the outer wall of the filter element end is tightly fitted with the sealing ring 5, and then the cylinder 9 is started through the clamping mechanism, and the output end of the cylinder 9 pushes the clamp 10 close to the other end of the filter element and plugs it in.

If there is a leak in the filter element, the gas pressure in the sealed chamber 1 will gradually decrease. The air pressure sensor 13 will detect this pressure change and output a corresponding signal to the data processing unit in the control module 12. The data processing unit determines whether there is a leak in the filter element based on the signal of the air pressure sensor 13 and outputs the leak detection result. The leak detection result is then fed back to the display screen through the control module 12;
