The extension part 3321 of the piston 332 is located inside the position limiting slot 3401, ensuring that the piston 332 moves along a straight line.

The rotating element 331 comprises a positioning hole 3310, a holder 3311, and an outer thread 3312. The positioning column 3350 of the cylinder 33 is located inside the positioning hole 3310, so as to limit the rotating element 331 on the cylinder 33. The two opposite ends of the connecting rod 35 are assembled, respectively, to the holder 3311 of the rotating element 331 and the positioning part 3322 of the piston 332.

The second rotating element 37 comprises a second outer thread 371 and a receiving hole 372. The second outer thread 371 cooperates with the outer thread 3312, so that when the second rotating element 37 rotates, it drives the rotating element 331 to rotate, and thus drives the connecting rod 35 to pull the piston 332 to move, so that the piston 332 performs a reciprocating movement inside the receiving space 3331 of the cylinder 33.

The cup lid 36 comprises a top wall 361 and a side wall 362 extending from the top wall 361. The top wall 361 and the side wall 362 enclose a space inside which the rotating element 331, the second rotating element 37, the piston 332, and the cylinder 33 are located. The rotating plate 38 is located outside the space. The top wall 361 comprises a recessed receiving part 3612 and a groove 3613, as well as a receiving hole 3614 that traverses the top wall 361 and a display hole 3615.

The rotating plate 38 is received inside the receiving part 3612. The rotating plate 38 comprises a covering part 380, a positioning pin 381 extending from the covering part 380, and a receiving slot 3801 located in the covering part 380. The handle 39 comprises a fixing part 390 located inside the receiving slot 3801, and a hand-held part 391 extending from the fixing part 390. The hand-held part 391 can be received inside the groove 3613. When the food processor according to the invention is being used, an operator can operate the hand-held part 391 to drive the rotating plate 38 to rotate. The positioning pin 381 of the rotating plate 38 traverses the receiving hole 3614, and is received inside the receiving hole 372 of the second rotating element 37. The cup lid assembly 3 comprises a positioning element 382 that is fixedly held to the positioning pin 381, so as to fix the rotating plate 38 and the second rotating element 37 to the cup lid 36.

The pressure indicating device 360 comprises a bracket 3601, an indicator 3602 fixed to the bracket 3601, and a venting tube 3603 connected with the bracket 3601. The indicator 3602 comprises a second space 36021 in communication with the space inside the cup body assembly 2. The venting tube 3603 puts the space inside the cup body assembly 2 and the second space 36021 in communication. The indicator 3602 comprises an elastic part 36020 exposed outside the display hole 3615. When the air pressure inside the cup body assembly 2 is lower than the atmospheric pressure, the air pressure inside the second space 36021 is also lower than the atmospheric pressure, and the elastic part 36020 is depressed towards the direction of the cup body assembly 2 under the effect of the atmospheric pressure, alerting a user. At this moment, the cup body assembly 2 is in a state of vacuum and pressure maintaining.

When the food processor according to the invention creates vacuum, the rotating plate 38 is rotated to drive the second rotating element 37 to rotate, and thus driving the rotating element 331 to rotate, so that the piston 332 moves outward inside the receiving space 3331 of the cylinder 33. During this process, the suction force created when the piston 332 moves causes the first blocking part 3102 of the first seal 310 to open. The gas inside the cup 210 passes the venting hole 312 of the sealing part 30 and the orifice 3340 of the cylinder 33, and enters the receiving space 3331. The suction force causes the first blocking plate 3302 of the second seal 330 to seal the through hole 3332 and the leaking holes 3333 such that outside air is unable to enter the receiving space 3331. The rotating plate 38 is further rotated such that the piston 332 moves inwards inside the receiving space 3331 of the cylinder 33, evacuating the air inside the receiving space 3331 through the leaking holes 3333 of the cylinder 33. During this process, since the pressure created when the piston 332 moves causes the first blocking part 3102 of the first seal 310 to seal the venting holes 312, the air inside the receiving space 3331 will not enter the cup 210. The pressure causes the first blocking plate 3302 of the second seal 330 to open. The air inside the receiving space 3331 is evacuated through the leaking holes 3333.

In the embodiments illustrated, the cup lid assembly 3 drives the rotating element 331 to rotate via the rotating plate 38. The invention is not limited to this. With reference to Figure 10, in another embodiment, the cup lid 5 comprises a cup lid inner thread 51 that cooperates with the outer thread 3312 of the rotating element 331. When the cup lid 5 rotates, it drives the rotating element 331 to rotate, which drives the connecting rod 35 to move, sucking out the air inside the cup body assembly 2 through the venting holes 312. The handle 39, the rotating plate 38 and the second rotating element 37 are omitted. The structure is simpler.

The cup lid assembly 3 of the food processor according to the invention sucks out the air inside the cup body assembly 2 through the venting holes 312 by driving the connecting rod 35 to move through the rotation of the rotating element 331. It has a simple structure and can easily create a vacuum.
