[0035] The present invention is described in detail below with reference to the accompanying drawings.

[0036] Embodiment 1

[0037] like Figure 1 , 2 , 3 show an anti-overflow structure for a food processor, wherein the food processor comprises a machine body 1, an electric control panel (not shown in the figure) arranged inside the machine body 1, a cup body 2 arranged on the machine body 1 and having an opening on the top, and a cup cover 3 arranged at the opening of the cup body 2.

[0038] The anti-overflow structure comprises

[0039] Anti-overflow electrode;

[0040] A lug is arranged on the cup cover 3 and has an end extending outward, and the lug is a conductive member;

[0041] A cup cover locking groove provided on the body 1;

[0042] A conductive sheet disposed on the cup cover 3, one end of which is electrically connected to the anti-overflow electrode and the other end of which is electrically connected to the lug;

[0043] A conductive contact member disposed in the cup cover locking groove;

[0044] The conductive contact is electrically connected to the electric control board through a wire;

[0045] When the cup cover 3 covers the opening of the cup body 2, the end of the lug on the cup cover 3 can be inserted into the cup cover locking groove on the body 1, and the end of the lug can contact and conduct with the conductive contact piece.

[0046] In this embodiment, the anti-overflow electrode is an electrode column arranged on the cup cover 3 and extending into the cup body, and the electrode column includes a first electrode column 51 and a second electrode column 52 arranged at intervals;

[0047] The cup cover 3 is provided with two lugs, namely a first lug 31 and a second lug 32, which are respectively arranged on two symmetrical sides of the cup cover 3, and one side of the first lug 31 and the second lug 32 are both embedded in the cup cover, and the ends thereof are both exposed and extend outward, and the first lug 31 and the second lug 32 are both conductive parts;

[0048] The body 1 has two corresponding cup cover locking grooves, namely a first cup cover locking groove 11 and a second cup cover locking groove 12. The first cup cover locking groove 11 and the second cup cover locking groove 12 are arranged on two symmetrical sides of the body 1 and can allow the first lug 31 and the second lug 32 to be inserted respectively.

[0049] The machine body 1 is also provided with a first opening 13 and a second opening 14 which are respectively connected with the first cup cover locking groove 11 and the second cup cover locking groove 12. When the cup cover 3 is closed on the opening of the cup body 2, the end of the first lug 31 on the cup cover 3 is embedded in the first opening 13, and the end of the second lug 32 is embedded in the second opening 14. When the cup cover 3 is rotated, the end of the first lug 31 passes through the first opening 13 and then enters the first cup cover locking groove 11, and the end of the second lug 32 passes through the second opening 14 and then enters the second cup cover locking groove 12;

[0050] The conductive contact members are also provided with two, namely, a first conductive contact member 61 and a second conductive contact member 62, which are respectively provided in the first cup cover locking groove 11 and the second cup cover locking groove 12;

[0051] The conductive sheet is also provided with two, namely, a first conductive sheet 41 and a second conductive sheet 42. One end of the first conductive sheet 41 is electrically connected to the first electrode column 51, and the other end is electrically connected to the first lug 31. One end of the second conductive sheet 42 is electrically connected to the second electrode column 52, and the other end is electrically connected to the second lug 32. The first conductive sheet 41 and the second conductive sheet 42 are both embedded in the cup cover 3.

[0052] The bottom of the cup body 2 is provided with a grounding pin; the cup body 2 needs to be a metal cup body, and at least part of the inner side of the cup body where the slurry contacts is connected to the grounding pin;

[0053] The anti-overflow structure forms an overflow slurry detection circuit through the electric control board → first conductive contact piece 61 → first lug 31 → first conductive sheet 41 → first electrode column 51 → overflow slurry → cup body grounding pin → electric control board; or forms an overflow slurry detection circuit through the electric control board → second conductive contact piece 62 → second lug 32 → second conductive sheet 42 → second electrode column 52 → overflow slurry → cup body grounding pin → electric control board.

[0054] In this embodiment, when the slurry is about to overflow, as long as the foam touches any electrode column, an overflow slurry detection circuit can be formed. Only when the electric control board receives the signal that the overflow slurry detection circuit is connected, it can stop heating to prevent the slurry from overflowing.

[0055] Embodiment 2

[0056] The anti-overflow structure in this embodiment is the same as that in the first embodiment. The difference from the first embodiment is that the overflow slurry detection circuit of the anti-overflow structure of this scheme does not need to be detected through the cup body grounding pin. The cup body 2 can be a metal cup body or a non-metal cup body. When the cup body 2 is non-metal, it is generally not necessary to set the cup body grounding pin. When the cup body is a metal cup body, it is often necessary to set the cup body grounding pin. At this time, the place where the inner side of the cup body contacts the slurry does not need to be connected to the grounding pin. The anti-overflow structure forms an overflow slurry detection circuit through the electric control board → first conductive contact member 61 → first lug 31 → first conductive sheet 41 → first electrode column 51 → overflow slurry → second electrode column 52 → second conductive sheet 42 → second lug 32 → second conductive contact member 62 → electric control board.

[0057] In this embodiment, when the foam touches the two electrode columns at the same time, the overflow slurry detection circuit will be connected. Only when the electronic control board receives the signal that the overflow slurry detection circuit is connected will the heating function of the food processor be stopped to prevent slurry overflow. Since the circuit of this scheme does not pass through the cup body grounding pin, it does not borrow the cup body grounding circuit and has less signal interference.

[0058] Embodiment 3

[0059] The cup cover 3 is provided with an opening curtain 33 with its opening facing the inside of the cup body, the anti-overflow electrode is a first conductive layer 34 coated on the opening curtain, and the conductive sheet is a second conductive layer 35 with one end electrically connected to the first conductive layer and the other end electrically connected to the two side lugs 31 and 32. The first conductive layer 34 and the second conductive layer 35 are connected as a whole to form the anti-overflow section of the cup cover, see Figure 4 shown.

[0060] In this embodiment, a grounding pin is provided at the bottom of the cup body 2, which is not shown in the figure; a grounding pin is provided at the bottom of the cup body 2, the cup body 2 needs to be a metal cup body, and the inner side of the cup body in contact with the slurry is at least partially connected to the grounding pin; the overflow prevention structure forms an overflow slurry detection circuit through the electronic control board → conductive contact piece → lug on either side → second conductive layer 35 → first conductive layer 34 → overflow slurry → cup body grounding pin → electronic control board.

[0061] In this embodiment, the anti-overflow electrode, the conductive sheet and the upper conductive layer are integrated into an anti-overflow section, which simplifies the structure, reduces protrusions, and makes it more convenient to clean the cup body.
