The food processor 100 of the present application can have a heating function, please refer to fig. 4, the food processor 100 further includes a heat-conducting aluminum plate 37 fixed on the lower surface of the cup chassis 35 and an electronic component 39 fixed on the lower surface of the heat-conducting aluminum plate 37, the electronic component 39 includes: the heating pipe 391, the temperature control sensor 395, the bottom water temperature sensor 393, the fuse 397 and the ground wire 399, the heat-conducting aluminum plate 37 is arranged around the groove wall of the installation groove 351, and the temperature control sensor 395, the bottom water temperature sensor 393, the fuse 397 and the ground wire 399 are arranged outside the heating pipe 391 at intervals. This application is through with temperature control sensor 395, bottom water temperature sensor 393, fuse 397 and earth connection 399 interval sets up in the outside of heating tube 391, so at the food processor operation in-process, the produced rotating magnetic field of drive disk 70 rotation in-process can not be to electronic components, especially the sensor produces the interference, thereby avoid electronic components to produce the condition of inefficacy or erroneous judgement because of the interference in magnetic field, thereby improve the life-span and the living environment of components and parts, the reliability of complete machine has been improved.

Because the food processor 100 of this application is magnetic drive, driven disk 50 and drive disk 70 can have great magnetic attraction in the axial, so after the stirring is eaten the material, when the edible material in the cup 30 of needs dumping, not only need overcome the gravity of stirring cup itself and still must overcome driven disk 50 and drive disk 70 at the ascending magnetic attraction of axial, can make the separation process of stirring cup subassembly 103 and frame subassembly 101 comparatively laborious and difficult like this. To solve the problem of the laborious separation process between the stirring cup assembly 103 and the base assembly 101, please refer to fig. 15 and 16, in some possible embodiments of the present application, an upper magnet 60 is fixed on the outer wall surface of the bottom of the cup bottom 35, a lower magnet 80 is disposed on the outer wall surface of the protective cover 13 (the upper surface of the portion of the protective cover 13 located in the barrel frame 71), and the upper magnet 60 and the lower magnet 80 are disposed opposite to each other in the vertical direction and are magnetically repulsive. The upper magnet 60 and the lower magnet 80 are both arranged annularly, in the design process, the distance between the upper magnet 60 and the lower magnet 80 in the vertical direction can be adjusted to adjust the mutual magnetic reaction force of the upper magnet 60 and the lower magnet 80, and the axial attraction force of the driven magnetic disk 50 and the drive magnetic disk 70 in the magnetic coupling process can be counteracted by the magnetic reaction force, specifically, the axial tension force generated by the axial attraction of the driven magnetic disk 50 and the drive magnetic disk 70 is set to be F1, the repulsive force provided by the upper magnet 80 and the lower magnet 80 is set to be F2, and the value range of F2/F1 is 1.5-3. So when the user need take off stirring cup subassembly 103, only need mainly overcome stirring cup subassembly 103 gravity can, the operation is got up laborsavingly to it is comparatively light convenient.

In order to further avoid the problem that the magnetic field rotating at a high speed may cause the conductive metal to cut the magnetic induction lines and generate heat, referring to fig. 15 and 16 again, an outer magnetic isolation member 79 is further disposed on the outer wall surface of the drive disk 70 corresponding to the outer sides of the plurality of drive magnets 75; and/or, the inner magnetism isolating piece 59 is arranged at the position corresponding to the inner side of the plurality of driven magnets 53 on the inner wall surface of the driven magnetic disk 50.

The present application preferably has magnetic spacers on both the outer wall surface of the drive disk 70 and the inner wall surface of the driven disk 50.
