The encapsulation 80 may include a coating portion 82 extending along the conductive member 76 and an encapsulation holding portion 83 protruding from the outside of the coating portion 82. In the illustrated embodiment, the covering 82 is substantially L-shaped. The rubber-covered abutting portion 83 surrounds the covering portion 82 and is annular. The rubber-covered abutting part 83 at least partially extends into the side wall through hole 512. The sidewall through hole 512 may be a step structure, and the probe sealing ring 81 is located in the sidewall through hole 512 and clamped between the rubber-covered abutting portion 83 and the step structure. Sealing and limiting are carried out in this way.

The conductive limiting member 63 is disposed through the first through hole 670 of the bottom wall 671 of the extending portion 67 and is accommodated in the via post 673, and the conductive limiting member 63 includes a limiting portion 631 protruding from the bottom wall 671 of the extending portion 67 for limiting and fixing the external member and the anti-overflow circuit. It is understood that the limiting portion 631 can be mutually limited and fixed with the receiving groove 235 at the top of the cup handle 23, and is electrically connected with the conductive transmission member 237 in the receiving groove 235, and further connected with the anti-overflow circuit. Extension 67 abuts the top end of cup handle 23 when cup lid assembly 14 is placed on blender cup assembly 12. The position-limiting portion 631 is electrically connected to the conductive transmission element 237 disposed in the receiving groove 235 at the top end of the cup handle 23. The position limiting portion 631 may protrude from the first through hole 670 to the bottom wall 671. Thus, the conductive position-limiting member 63 can move up and down along the via post 673, i.e., the axial direction of the first through hole 670, and the via post 673 can guide the conductive position-limiting member 63. When the cup lid 51 is assembled on the cup body 21 and rotates to the right position, the limiting part 631 protrudes from the bottom wall 671 to be clamped and matched with the containing groove 235 at the top of the cup handle 23, so that the positions of the cup lid 51 and the cup body 21 are limited, and the cup lid 51 is prevented from being automatically unscrewed and deviating from the position of the cup body 21 during the operation and stirring process of the food processor.

The top of the conductive limiting member 63 may be provided with a guiding portion 632, the guiding portion 632 is sleeved with an elastic member 633, and the top end of the elastic member 633 abuts against the top cover 672. When the lid 51 is assembled to the cup 21 and rotated to a proper position, the elastic member 633 can provide a downward elastic force to the conductive position-limiting member 63, so that the position-limiting portion 631 protrudes from the bottom wall 671 and is further clamped in the receiving groove 235 at the top of the cup handle 23, thereby preventing the lid 51 from being automatically unscrewed and deviating from the position of the cup 21. In this embodiment, the elastic member 633 may be a spring.

The sidewall of the receiving groove 235 at the top of the cup handle 23 may be an arc surface or a frustum surface, and the limiting portion 631 of the conductive limiting member 63 may be a corresponding arc structure or a frustum structure. When the food processor normally works, the elastic member 633 always provides elastic force to the conductive position-limiting member 63 during the stirring of the food material, so that the limiting portion 631 of the conductive position-limiting member 63 is clamped in the accommodating groove 235 at the top of the cup handle 23, and the cup cover 51 is prevented from being automatically unscrewed and deviating from the position of the cup body 21. When the user rotates the cup lid 51, the limiting portion 631 and the receiving groove 235 are engaged with each other by an inclined surface or an arc surface, and the limiting portion 631 can gradually separate from the receiving groove 235 along the sidewall of the receiving groove 235, so that the user can rotate the cup lid 51 to separate from the cup body 21.

The conductive member 64 is housed in a housing portion surrounded by the bottom wall 671 and the top cover 672, and the top cover 672 hides the conductive member 64, the conductive stopper 63 and the protruding portion 621 of the overflow prevention probe 62, thereby achieving an effect of beautiful appearance. A first end (left end as viewed in fig. 5) of the conductive member 64 is conductively connected to the protrusion 621 of the anti-overflow probe 62, and a second end (right end as viewed in fig. 5) of the conductive member 64 is conductively connected to the conductive stopper 63. The conductive member 64 may be a metal connecting piece or a wire as long as the overflow preventing probe 62 and the conductive limiting member 63 can be electrically connected to each other. The conductive limiting member 63 may be a rod structure, and is made of a conductive material such as stainless steel. In one embodiment, the second end of the conductive member 64 may be welded to the conductive stopper 63. The overflow prevention probe 62 and the conductive limiting member 63 are conductively connected with each other through the conductive member 64, so that an overflow prevention circuit is formed together with the conductive transmission member 31, and an overflow prevention signal can be transmitted to the overflow prevention circuit.

In another embodiment, the conductive member 64 may be bent into a plurality of bent segments so long as it is capable of bypassing the containment wall 674, which is not a limitation of the present application.

When the cup lid 51 is assembled to the cup body 21 and rotated to a proper position, the second coupler 677 is coupled with the first coupler 234, the position-limiting portion 631 of the conductive position-limiting member 63 contacts the conductive transmission member 237 in the receiving slot 235 at the top of the cup handle 23, the conductive position-limiting member 63 is electrically connected with the protruding portion 621 of the overflow-preventing probe 62 through the conductive member 64, and the overflow-preventing probe 62 is electrically connected with the control circuit board inside the host 11. In the working process of the cooking cup, the liquid level of the heated food material in the cup body 21 or the generated foam rises, when the water level is over or contacts the detection part 77 of the anti-overflow probe 62, an electric signal is generated, the electric signal is transmitted to the protruding part 621 through the detection part 77 of the anti-overflow probe 62, the protruding part 621 transmits the electric signal to the conductive limiting part 63 through the conductive part 64, the conductive limiting part 63 transmits the electric signal to the conductive transmission part 237, and the conductive transmission part 237 transmits the electric signal to the control circuit board in the host 11. The control circuit board receives an electric signal indicating that the food material overflows quickly, and controls the heating pipe or other heating devices of the cup chassis to stop heating or to heat at low power, so that the overflow prevention is realized, and the food in the cup body 21 is prevented from overflowing. Moreover, the anti-overflow detection can be triggered only after the conductive limiting part 63 is conductively communicated with the conductive transmission part 237 in the containing groove 235 at the top of the cup handle 23, and the cup cover 51 is separated from the cup body 21 when the cup body 23 is generally cleaned, so that the anti-overflow misjudgment caused by the fact that liquid contacts the anti-overflow probe 62 when the cup body is cleaned can be effectively avoided.

The cooking machine of this application embodiment when bowl cover subassembly lid is established on stirring cup subassembly, the spacing portion of electrically conductive locating part can the joint in the accepting groove at cup handle top, and then with the extension of bowl cover with if cup handle is spacing fixed each other, prevent to take off under cooking machine operating condition between bowl cover and the cup handle. Meanwhile, the limiting part of the conductive limiting part is conductively connected with the conductive transmission part in the accommodating groove at the top of the cup handle, an anti-overflow loop can be formed together with the protruding part of the anti-overflow probe and the conductive part, the anti-overflow signal is conducted, and anti-overflow is achieved.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
