[0024] In use, the operator first puts the krypton-xenon raw material liquid oxygen into the inner tank 3, and in the conveying process, when encountering bumps, when the inner tank 3 shakes, the first damping mechanism 4, the second damping mechanism 5 and the third damping mechanism 6 can dampen different directions of the inner tank 3, avoid the inner tank 3 from producing violent vibration, and also can reduce the incidence of explosion, facilitating the subsequent operation.

[0025] Referring to Figure 2 and Figure 3The first damping mechanism 4 comprises a fixed block 41, a sliding block 42, a first spring 43, and a fixed plate 44.
