[0029] The indicating mechanism comprises a mounting block 601 fixedly connected to the side wall of the box body 101, a plurality of scale blocks 602 arranged in an array are fixedly connected to the top of the mounting block 601, and a pointer block 603 is fixedly connected to the side wall of the sliding plate 404; when the sliding plate 404 slides on the side wall of the fixed rod 501, the pointer block 603 is driven to move, and the pressure in the refrigeration preservation box 1 can be more directly determined by observing the corresponding scale block 602 of the pointer block 603.

[0030] Working principle: in operation, first, the food materials such as vegetables or seafood are placed in the box body 101 of the refrigeration preservation box 1, then the box cover 102 is covered, and the sealing strip 103 on the box cover 102 is tightly attached to the box body 101, then the rotating handle 203 is rotated, the rotating disc 202 is driven to rotate through the rotating rod 208, the pushing block 204 on the rotating disc 202 rotates together with the rotating disc 202, when the first inclined surface 205 on the pushing block 204 abuts against the second inclined surface 207 on the pushing rod 206, the second inclined surface 207 slides on the first inclined surface 205, at this time, the piston plate 12 is driven to move away from the rotating disc 202 through the pushing rod 206, the air in the air cylinder 8 is compressed, at this time, the first one-way valve 9 in the air suction pipe 7 is closed and the second one-way valve 11 in the air outlet pipe 10 is opened under the action of the air pressure, then the compressed air in the air cylinder 8 is discharged through the air outlet pipe 10, and the first spring 303 is stretched by the piston plate 12.

[0031] When the first inclined surface 205 passes the second inclined surface 207, the piston plate 12 is pulled back to the original position under the action of the first spring 303, which is a prerequisite for the abutment of the first inclined surface 205 and the second inclined surface 207 in the next cycle, when the piston plate 12 is pulled back to the original position, a negative pressure is generated in the air cylinder 8, at this time, the second one-way valve 11 in the air outlet pipe 10 is closed and the first one-way valve 9 in the air suction pipe 7 is opened under the action of the air pressure, at the same time, the air in the refrigeration preservation box 1 is sucked into the air cylinder 8 through the air suction pipe 7, the air pressure in the refrigeration preservation box 1 becomes smaller, and the air pressure in the refrigeration preservation box 1 continuously becomes smaller through the reciprocating movement, and finally approaches a vacuum state, which can reduce the oxygen content in the refrigeration preservation box 1, slow down the oxidation process of the food materials, prevent the growth of bacteria and fungi, and prolong the refrigeration preservation time of the food materials.

[0032] When the air pressure in the refrigeration preservation box 1 becomes smaller, the air pressure in the fixed pipe 401 connected thereto also becomes smaller, at this time, there is an air pressure difference between the two sides of the piston 402, which drives the piston 402 to move towards the box body 101, drives the sliding plate 404 to slide on the side wall of the fixed rod 501 through the connecting rod 403, and compresses the second spring 502, when the sliding plate 404 slides on the side wall of the fixed rod 501, the pointer block 603 is driven to move, and the air pressure in the refrigeration preservation box 1 can be determined by observing the corresponding scale block 602 of the pointer block 603.

[0033] In addition, the air tightness of the cold storage case 1 is detected before the food is stored in the cold storage case 1. After the lid 102 is closed, the air is pumped out, and after the pumping is stopped, if the pointer block 603 rebounds, the air tightness of the cold storage case 1 is insufficient. At this time, the air tightness of each connection is checked, the sealing strip 103 is wiped, and if the air tightness is still insufficient, a new sealing strip 103 needs to be replaced or another cold storage case 1 is used for cold storage and transportation. In addition, during the transportation process, whether the air pressure in the cold storage case 1 is constant can be determined by observing whether the scale block 602 corresponding to the pointer block 603 changes, so that the air pressure in the cold storage case 1 can be monitored in real time, the air tightness is prevented from being insufficient, the vacuum effect in the cold storage case 1 is ensured, outside air is prevented from entering, and the cold storage time of the food is prolonged.

[0034] When the cold storage of the food is completed, the lid 102 is opened, at this time, the air pressure inside and outside the box body 101 is consistent, the piston 402 is not affected by the air pressure difference, and under the action of the second spring 502, the sliding plate 404 drives the piston 402 to move back to the original position through the connecting rod 403. When the sliding plate 404 abuts against the limiting block 503, the resetting is completed.

Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced in the present application.
