The sealing strip 44 and the sealing groove 43 are both set to a circular shape. After the sealing strip 44 is embedded in the sealing groove 43, the triangular clamping block 48 is just embedded in the annular groove 411. After the triangular clamping block 48 is embedded in the annular groove 411, the end of the push rod 46 is just in contact with the surface of the storage tank 1. The sealing strip 44 is made of rubber material and is used to push the blocking block 41 so that the sealing strip 44 can be inserted into the sealing groove 43. At the same time, the triangular clamping block 48 is inserted into the annular groove 411 to achieve the positioning of the push rod 46, and then the positioning of the blocking block 41 is achieved.

In order to discharge the air in each storage cavity, the piston 52 inside the driving cylinder 51 can be continuously reciprocated up and down by pressing the pressure rod 54, cooperating with the driving rod 53 and the driving spring 55. When the piston 52 moves downward, the air in each storage cavity can be extracted. When the piston 52 moves upward, the air inside the driving cylinder 51 can be quickly discharged through the exhaust pipe 56, and so on and so forth, so that the air in each storage cavity can be discharged in a concentrated manner (a small amount of air cannot be discharged without affecting the implementation of the scheme). When it is necessary to extract the air in the separate storage chamber, push the rubber rotating column 62 upward so that the top of the rubber conversion column 22 is blocked by the sealing disk 66. At this time, the rubber rotating column 62 is driven to rotate by the adjusting rod 63, so that when the adjusting rod 63 is rotated to the corresponding label position, the horizontal hole 67 can be connected with the corresponding connecting pipe 68, and then, by continuously pressing the pressure rod 54, cooperating with the driving rod 53 and the driving spring 55, the piston 52 inside the driving cylinder 51 can continuously move up and down to realize the separate air extraction operation.
