Referring to fig. 1 and 2, a vacuum food processor includes: the cup body assembly 100 comprises a base 110 and a cup body assembly 120, the cup body assembly 120 is arranged on the base 110, a cup cavity 121 is formed in the cup body assembly 120, a vacuumizing butt joint part 122 is arranged on the cup body assembly 120, and air in the cup cavity 121 can be exhausted through the vacuumizing butt joint part 122; the outer lid assembly 200 comprises an outer shell 210 and a vacuumizing butt joint part 220, wherein the vacuumizing butt joint part 220 is movably connected with the outer shell 210, the vacuumizing butt joint part 220 can generate preset displacement relative to the outer shell 210, a vacuumizing chamber 230 is formed on the vacuumizing butt joint part 220, the vacuumizing chamber 230 is provided with a butt joint opening part 231, the outer lid assembly 200 can be covered on the cup body assembly 120, and the butt joint opening part 231 is abutted to the exhaust side of the vacuumizing butt joint part 122; a vacuum pumping device 300 connected to the vacuum pumping interface 220 and capable of pumping the pumping chamber 230; a control valve 400 disposed on the main body assembly 100 and having an open state and a closed state, wherein the pumping chamber 230 can communicate with the outside through the control valve 400, the control valve 400 is provided with a control end 411, and when the cover assembly 200 is covered on the cup assembly 120, the control end 411 of the control valve 400 can be touched to close the control valve 400; when the cover assembly 200 is opened and the outer housing 210 is displaced relative to the vacuum connection 220, the outer housing 210 releases the control end 411 to open the control valve 400.

When the cup cavity 121 needs to be evacuated, the cover assembly 200 is covered on the cup body assembly 120, the control end 411 of the control valve 400 is touched to enter the closed state, the evacuation device 300 evacuates the evacuation cavity 230 to form a negative pressure, and the air in the cup cavity 121 is circulated into the evacuation cavity 230 through the evacuation interface portion 122 and is evacuated by the evacuation device 300. As the evacuation chamber 230 creates a negative pressure, the evacuation interface 220 will be drawn tight onto the evacuation interface 122. Due to the relative displacement between the outer housing 210 and the evacuation interface 220, the control end 411 of the control valve 400 is released by the relative movement of the outer housing 210, so that the control valve 400 can communicate the evacuation chamber 230 with the outside, and the vacuum state of the evacuation chamber 230 is broken, thereby facilitating the removal of the entire lid assembly 200. The vacuum pumping device with the structure has the advantages of simple structure for eliminating negative pressure and lower cost. In addition, because the vacuumizing butt joint piece 220 is movably arranged, the influence of poor sealing caused by cover closing errors can be effectively reduced. It should be understood that the outside environment described in the present embodiment refers to the external atmosphere, and the communication mode may be direct communication or indirect communication.

Referring to fig. 3 and 4, in the embodiment, the outer shell 210 is pivotally connected to the base 110 and can rotate to open or rotate to close relative to the base 110, and after the outer shell 210 rotates to close, the outer lid assembly 200 covers the cup body assembly 120. In this embodiment, the outer shell 210 is pivotally connected to the base 110, and when the cup cavity 121 needs to be vacuumized, the outer shell 210 can be rotated and folded, so that the cover assembly 200 can be conveniently closed.

In this embodiment, the outer housing 210 and the base 110 are correspondingly provided with a snap-fit structure, and after the outer housing 210 rotates and is folded relative to the base 110, the outer housing 210 and the base 110 can form a snap-fit connection through the snap-fit structure. The outer housing 210 can be firmly connected to the base 110 by the snap-fit structure, and the outer lid assembly 200 cannot be easily opened, so that the vacuum processor is stable in working condition. In some embodiments, the snap-fit structure may be a combination of an elastic buckle and a detent, the elastic buckle is connected to an operating portion, and the elastic buckle is deformed by the operating portion to disengage the elastic buckle from the detent, so as to release the snap-fit between the outer housing 210 and the base 110.

Of course, in other embodiments, the specific manner of movably connecting the vacuum pumping interface 220 and the outer housing 210 is not limited, as long as the two can generate a predetermined relative displacement, and the outer housing 210 can release the control end 411 of the control valve 400 through the relative displacement.

The control end 411 of the control valve 400 is touched and released by utilizing the closed position and the open position of the outer shell 210, so that the design is ingenious and the operation is convenient. In some embodiments, other structures may be adopted to control the control valve 400, for example, the control valve 400 is disposed on the outer shell 210, when the outer shell assembly 200 is covered on the cup body assembly 120, the control end 411 of the control valve 400 is contacted with the main body assembly 100 to close the control valve 400, when the outer shell assembly 200 is opened, the outer shell 210 is first displaced relative to the vacuum pumping butt-joint element 220 by a predetermined displacement, the main body assembly 100 can release the control end 411 of the control valve 400 by the predetermined displacement, so as to open the control valve 400, the vacuum degree of the air pumping chamber 230 is broken, and the entire outer shell assembly 200 can be opened.
