wherein the cup cover is concavely formed with a slot, the vacuum pumping device comprises a housing and a pumping power element provided in the housing, the housing is provided with an insertion portion embedded in the slot, and the pumping power element is at least partially provided in the insertion portion.

2. The food processor of claim 1 , wherein food processor further comprises a waterproof and breathable structure configured to block food residues and liquid in the cup body from entering the vacuum pumping device;
wherein:
the pumping opening is defined on a bottom wall of the slot, and the pumping hole is provided in the insertion portion;
the pumping opening is lower than an upper edge of the cup body; and
the pumping opening is located in a middle of the cup cover.

3. The food processor of claim 2 , wherein a shape of a vertical section of the slot is trapezoidal or square, and an external contour shape of the insertion portion is adapted to the shape of the vertical section of the slot.

4. The food processor of claim 3 , wherein a depth of the slot is a dimension of the slot extending in an axial direction of the cup body, and the depth of the slot is 5 mm to 50 mm.

5. The food processor of claim 2 , wherein the vacuum pumping device further comprises a first power supply structure, the pumping power element is electrically connected to the first power supply structure, the food processor further comprises a base, the cup body is mounted on the base, the base is provided with a second power supply structure, and the first power supply structure and the second power supply structure are independent of each other.

6. The food processor of claim 2 , wherein a clamping slot is formed on an outer wall of the housing, the clamping slot is configured to surround the insertion portion, a first sealing ring is mounted in the clamping slot, and the first sealing ring is clamped by the vacuum pumping device and the cup cover after the vacuum pumping device is mounted on the cup cover.

7. The food processor of claim 2 , wherein the cup cover is connected with a connecting portion at a periphery of the pumping opening, the connecting portion is configured to extend towards the inner cavity of the cup body, the vacuum pumping device protrudes from a sealing ring mounting portion at an outer wall of the insertion portion, the pumping hole is located inside the sealing ring mounting portion, the sealing ring mounting portion is configured to partially extend into the connecting portion and is connected to the connecting portion, a first sealing ring is sleeved outside the sealing ring mounting portion, and the first sealing ring is clamped by the vacuum pumping device and the cup cover after the vacuum pumping device is mounted on the cup cover.

8. The food processor of claim 7 , wherein the first sealing ring is clamped between the outer wall of the insertion portion and the bottom wall of the slot.

9. The food processor of claim 7 , wherein:
both the sealing ring mounting portion and the connecting portion are cylindrical;
the first sealing ring is clamped between the sealing ring mounting portion and the connecting portion; or
