[0033] Then when one of the inflatable cavities 102a is filled with air (the pressure of the air bag 102 is detected by the sensor), the first cylinder 112 drives the first rotating disc 113 to rotate, the guide column 110 is partially located in the guide groove 113a, the fixed block 109 is fixed with the sealing column 103, the sealing column 103 moves along the first sliding groove, so that the first rotating disc 113 drives the fixed block 109 and the sealing column 103 to move through the guide column 110, so that the sealing column 103 closes the second pipeline 119. Then the first magnetic block 115 corresponding to the inflatable cavity 102a is powered on, the second magnetic block 116 is powered off, which will make the iron block 114 attracted to the first magnetic block 115, so that the guide column 110 corresponding to the inflatable cavity 102a is separated from the guide groove 113a, and then the first cylinder 112 drives the first rotating disc 113 to move through the guide column 110, drives the fixed block 109 and the sealing column 103 to move, so that the remaining sealing column 103 which is not filled with air opens the second pipeline 119, until all the inflatable cavities 102a are filled. Thus, the sealing of the shell 101 and the end cover is ensured, and when part of the inflatable cavities 102a are filled with air, the corresponding inflatable cavities 102a are closed, so that the gas can be concentrated and delivered to the remaining inflatable cavities 102a which are not filled, thereby ensuring the rapid sealing of the shell 101 and the end cover.

[0034] Finally, the inside of the shell 101 is pumped by a vacuum pump, and in a vacuum (low pressure) environment, the boiling point of water is significantly reduced, so that the water can evaporate at low temperature, avoiding high temperature damage to the material.
