[0040] Working principle of the present invention:

[0041] First, fit the positioning box 12 into the storage box 11, and then fit the liner 13 into the positioning box 12, place the food into the liner 13 for storage, and then cover the upper cover 211 on the positioning box 12. At this time, the fixing plate 221 fits and presses on the top of the positioning box 12, and the positioning box 12 squeezes the pressing block 2245 to push up the sliding connection plate 2242, so that the sliding connection plate 2242 drives the deflation plug 2243 to move upward, so that the sealing head 2244 fits with the fixing plate 221, preventing the juice in the food from flowing into the fixing plate 221.

[0042] When the upper cover 211 is opened, the fixing plate 221 and the positioning box 12 are no longer fitted together, which means that the positioning box 12 no longer squeezes the pressing block 2245. The compression deformation of the spring 22412 facilitates the downward pressure on the sliding connecting plate 2242, which involves the sliding connecting plate 2242 driving the air release plug 2243 to move downward, so that the blocking head 2244 no longer blocks the interlaced gap between the air release plug 2243 and the fixing plate 221. At the same time, the strip groove on the air release plug 2243 is horizontally inserted into the interior of the fixing plate 221. At this time, the top of the inner cavity of the strip groove is connected with the inner cavity of the fixing plate 221, and the bottom of the inner cavity of the strip groove is connected with the inner cavity of the inner liner 13, thereby releasing the seal on the inner cavity of the inner liner 13, so that the air pressure of the inner liner 13 is restored when the cover is opened, which facilitates the cover opening action.
