[0023] The following describes the present invention in detail with reference to the embodiments of the drawings.

[0024] As Figure 1 and Figure 2 shown in the anti-overflow structure of the food processor, the food processor includes a machine body 1, a main electronic control board arranged in the machine body 1, a cup body 2 arranged on the machine body 1 with an opening at the top, a pot lid 3 arranged at the opening of the cup body 2, and a latch arranged on the machine body 1 for locking the cup body 1 with the pot lid 3 installed.

[0025] The latch includes a left latch 81 located above one side of the cup body 1 and a right latch 82 located above the other opposite side of the cup body 1. The middle parts of the left latch 81 and the right latch 82 are rotatably arranged on the machine body 1. A driving motor 9 is arranged in the machine body. The driving motor 9 is connected to the left latch 81 and the right latch 82 through a transmission mechanism to drive the left latch 81 and the right latch 82 to act simultaneously, so as to lock or release the lock on the pot lid 3; The transmission mechanism is shown in Figure 3 , 4 shown, and it includes:

[0026] The V-shaped drive frame 10 is connected to the drive motor 9 in the middle and can rotate under the drive of the drive motor 9;

[0027] The left linkage rod 11, the first end of the left linkage rod 11 is connected to one end of the V-shaped drive frame 10, and the second end of the left linkage rod 11 is connected to one end of the left lock 81;

[0028] The right linkage rod 12, the first end of the right linkage rod 12 is connected to the other end of the V-shaped drive frame 10, and the second end of the right linkage rod 12 is connected to one end of the right lock 82;

[0029] After the drive motor 9 rotates, it drives the V-shaped drive frame 10 to rotate, and then drives the left lock 81 and the right lock 82 to rotate downward to press the cup lid or rotate upward to release the cup lid through the left linkage rod 11 and the right linkage rod 12, so that the left lock 81 and the right lock 82 lock the cup lid 3 at the same time or release the lock on the cup lid 3 at the same time.

[0030] A strong electric micro switch is provided beside the left lock 81 or the right lock 82 on the body. The strong electric micro switch is triggered after the left lock 81 or the right lock 82 locks the cup lid 3, and is in an off state when the left lock 81 or the right lock 82 releases the lock on the cup lid 3; the strong electric micro switch is connected in series in the power supply circuit of the main electronic control board.

[0031] A wireless anti-overflow structure is provided between the body 1 and the cup lid 3. The anti-overflow structure includes:

[0032] The anti-overflow electrode, the anti-overflow electrode is an electrode post arranged on the cup lid 3 and extending into the cup body. The electrode post includes a first electrode post 61 and a second electrode post 62 arranged at intervals. The axial center distance between the first electrode post 61 and the second electrode post 62 is b, 20mm ≤ b ≤ 200mm; preferably 40mm ≤ b ≤ 80mm;

[0033] The cup lid induction coil 4 arranged in the cup lid 3, and the cup lid induction coil 4 is annularly distributed in the cup lid 3;

[0034] The cup lid induction coil control board 5 arranged in the cup lid 3. The first electrode post 61 and the second electrode post 62 are respectively electrically connected to the first conductive sheet 31 and the second conductive sheet 32. Both the first conductive sheet 31 and the second conductive sheet 32 are electrically connected to the cup lid induction coil control board 5 through wires. The first conductive sheet 31 and the second conductive sheet 32 are embedded in the cup lid 3; the first electrode post 61, the second electrode post 62, the cup lid induction coil control board 5 and the cup lid induction coil 4 together constitute the anti-overflow signal acquisition part;

[0035] The lock induction coil 7 arranged in the right lock 82;

[0036] The buckle induction coil 7 is electrically connected to the main electronic control board through a wire. The buckle induction coil 7 and the main electronic control board together constitute the overflow prevention signal receiving part; the distance between the lid induction coil and the buckle induction coil is less than or equal to 30 mm; when the buckle locks the cup body 1 with the cup lid 3, the buckle induction coil in the buckle is just located above the lid induction coil.

[0037] When the cup lid 3 is closed on the opening of the cup body 2, the buckle induction coil and the lid induction coil are inductive. The buckle induction coil supplies power to the lid induction coil. At the same time, the control board of the lid induction coil sends the overflow prevention signal collected by the overflow prevention electrode to the buckle induction coil through the lid induction coil, and then sent to the main electronic control board by the buckle induction coil.

[0038] In this embodiment, the structure of the control board 5 of the lid induction coil adopts conventional technology, and integrates a coding circuit and a driving circuit for the lid induction coil; the main electronic control board integrates a high-frequency discrimination signal source, a decoding circuit, a shaping circuit, and a driving circuit for the buckle induction coil.

[0039] During operation, when the pot lid is placed in place, the driving motor 9 drives the left and right linkage rods through the driving frame 10 to make the left and right buckles flip downwards to press the cup lid. At this time, the buckle coil and the pot lid coil are inductive. The former supplies wireless power to the latter, and the latter feeds back the weak electrical signal for locking the pot lid to the former. At the same time, the strong electrical micro switch is touched by the buckle to connect the physical strong electrical circuit. When the reduction motor rotates in the reverse direction and drives the left and right linkage rods through the driving frame to release the left and right buckles from the pot lid, the buckle coil and the pot lid coil no longer interact to obtain the weak electrical signal of the pot lid. At this time, the program determines that the whole machine is in a non-working state, and stops beating and heating. At the same time, the buckle no longer touches the strong electrical micro switch, cutting off the strong electrical supply circuit for beating and heating. In this way, double protection of strong and weak electricity is achieved at the same time.
