Specifically, when the connection column 141 of the vacuum pump 140 is hermetically connected to the inner wall of the pumping hole 131a, a sealing ring may be disposed between the connection column 141 and the inner wall of the pumping hole 131 a; of course, an internal thread may be disposed on the inner wall of the air exhaust hole 131a, and an external thread may be disposed on the outer wall of the connection column 141, so that the sealing effect of the internal thread and the external thread is achieved by screwing the internal thread and the external thread.
In addition, the shape of the isolation buffer cavity 170 is not limited, and may be, for example, a circle, a polygon, or the like. The isolation buffer cavity 170 may be connected to the housing by an integral connection structure or a separate connection structure. It is understood that the container to be evacuated mentioned above may be a cup, a tub, a bag, or the like.

By dividing the housing into the upper cover 110 and the lower cover 130, when the mounting bracket 120 is detachably connected to the upper cover, the vacuum pump 140 and other parts can be mounted on the mounting bracket 120, and then the mounting bracket 120 is connected to the upper cover 110, so that the assembly is easy for a worker, and the problem that large parts are difficult to assemble is avoided. Similarly, the above effect can be achieved when the mounting bracket 120 is detachably connected to the lower cover 130, or when the mounting bracket 120 is detachably connected to both the upper cover 110 and the lower cover 130. Specifically, the detachable connection manner includes a snap connection, a screw connection, a magnetic connection, or the like.

Specifically, the pressure relief switch assembly includes a pressure relief valve 150, and the effect of venting gas through the pressure relief valve 150 (or blocked by the pressure relief valve 150) is achieved by controlling the open (or closed) state of the pressure relief valve 150.
On the basis that the lower cover 130 has the pressure relief hole 131b, the pressure relief hole 131b is opened in the bottom wall of the tank body and is communicated with the isolation buffer cavity 170.
Through communicating pressure release hole 131b with isolation buffer memory chamber 170 for outside air through relief valve 150 can pass pressure release hole 131b and get into isolation buffer memory chamber 170, and then gets into the container through the sieve mesh 181 of apron 180 in, thereby realize the pressure release process, realize the effect that the atmospheric pressure of outside air and air in the container is the same, make the user open the lid of container more easily, further eat the edible material in the edible container.
Further, the lower cover 130 may be detachably connected with a sealing ring, which surrounds the outside of the tank body.
