By providing the pumping box 304, the connection of the vacuum pump to the first pumping port 310 can be easily achieved. When the pumping base 300 has a plurality of first pumping ports 310, a plurality of pumping boxes 304 are correspondingly arranged. For example, the pumping base 300 has three first pumping ports 310 corresponding to the three pumping boxes 304.

The vacuum storage device 200 of the present embodiment may be configured to be evacuated at a regular time. Each air exhaust base 300 is internally provided with a vacuum pump, but a plurality of storage boxes 400 can be correspondingly arranged, so that the number of the storage boxes 400 on the air exhaust base 300 can be firstly determined, and the total air exhaust time is determined based on the number of the storage boxes 400 and the air exhaust time of each storage box 400.

In some embodiments, as shown in fig. 5 and 7, the vacuum storage device 200 of the present embodiments further comprises a micro switch 305 and a pneumatic pressure sensing unit 405. As shown in fig. 7, the micro switch 305 is disposed on the pumping base 300 and electrically connected to the vacuum pump such that the micro switch 305 is triggered to turn on the vacuum pump. Specifically, the micro switch 305 is disposed in the pumping base 300 by using the fixing frame 350 and senses that the head portion exceeds the through hole 316 of the top wall of the pumping base 300 and is disposed opposite to the air pressure sensing unit 405. When the microswitch 305 is triggered, the vacuum pump is turned on to pump; when the micro switch 305 is not triggered, the vacuum pump does not pump air, so that the air pumping control of the storage box 400 is simple. As shown in fig. 5, the outer shell 402 further forms an air pressure sensing cavity, a first through hole 421 communicating with the storage space 410 is formed on a top wall of the air pressure sensing cavity, and a second through hole 422 communicating with the outside is formed on a bottom wall of the air pressure sensing cavity. The air pressure sensing unit 405 is disposed in the air pressure sensing cavity and includes a flexible deformation member 451 and a spring 452. The spring 452 is interposed between the first through hole 421 and the flexible deformation member 451. The flexible deforming member 451 may include: a deformation part (not numbered in the figure), a fixing part (not numbered in the figure) and a guide part (not numbered in the figure), wherein the deformation part is arranged at the second through hole 422, the fixing part extends outwards from the periphery of the deformation part, and the guide part extends from the deformation part to the side far away from the second through hole 422; the spring 452 is sleeved outside the guide portion. The flexible deformation member 451 is held within the air pressure sensing chamber by the fixing portion. The guide portion provides a guide for the up-and-down movement of the spring 452. When the air pressure in the storage space 410 is higher than the preset air pressure value, the deformation part of the flexible deformation member 451 deforms downward, protrudes out of the second through hole 422, contacts with the micro switch 305, triggers the micro switch 305, and the vacuum pump is turned on to pump air. When the air pressure in the storage space 410 is lower than the preset air pressure value, the flexible deformation member 451 deforms upward due to the difference between the internal air pressure and the external air pressure, and does not protrude from the second through hole 422, and meanwhile, the spring 452 is compressed, so that the air pressure sensing unit 405 moves upward as a whole. At this time, the microswitch 305 and the air pressure sensing unit 405 are no longer in contact, and the air suction is stopped. After a period of time, if air leakage occurs in the storage box 400, the deformation part protrudes out of the second through hole 422 again, the vacuum pump is started again to exhaust air when the deformation part contacts the micro switch 305, and the air pressure in the storage box 400 is ensured to be always within the required air pressure range in a reciprocating mode. The vacuum pump switch is controlled by the air pressure sensing unit 405 and the microswitch 305, the air suction time does not need to be calculated, and the control logic is simpler.
