[0029] Reference Figures 1 to 3The motor of the embodiment of the utility model includes a stator 100, a rotor 200 and a heating plate 300. A rotating hole 110 is penetrated in the middle of the stator 100; a rotating shaft 210 is fixedly connected to the rotor 200, and the rotor 200 can be pivotally built into the rotating hole 110; a through hole 310 is penetrated in the middle of the heating plate 300, and the rotating shaft 210 can pivotally penetrate the through hole 310, and a connecting column 340 is fixedly connected between the heating plate 300 and the stator 100.

[0030] In actual processing, the motor structure of this embodiment only needs to process the stator 100, the rotor 200 with the rotating shaft 210, and the heating plate 300, wherein the stator 100 and the rotor 200 are driven by the electromagnetic principle to stably pivot the rotating shaft 210, which belongs to the driving principle of an ordinary motor and is not described in detail here. The rotating shaft 210 is used to connect the stirring mechanism in the wall breaking machine, and the rotating shaft 210 provides the stirring mechanism with a pivoting torque, thereby crushing and stirring the food in the wall breaking machine, and the heating plate 300 is a container for holding food in the wall breaking machine. The hot plate 300 is the bottom plate of the storage space in the wall breaking machine. The rotating shaft 210 passes through the heating plate 300 and extends out of the heating plate 300, and is connected to the above-mentioned stirring mechanism to realize the function of stirring and heating the food at the same time. Specifically, during the assembly process, the rotor 200 is embedded in the rotating hole 110 of the stator 100. At the same time, the rotating shaft 210 on the rotor 200 is inserted into the heating plate 300, and the rotating shaft 210 can and can only pivot on the heating plate 300, and the rotor 200 can and can only pivot in the stator 100.

[0031] It should be emphasized that the connection structure between the stator 100 and the rotor 200 is a commonly used structure in the field of motors and will not be described in detail here. Only one of the ways is taken as an example. In the motor of the embodiment of the utility model, the motor also includes a frame 400, the frame 400 and the stator 100 are fixedly connected, and the rotating shaft 210 is inserted into the frame 400, and the rotating shaft 210 can and can only rotate around the axis on the frame 400. The frame 400 can achieve rotational cooperation with the rotating shaft 210 through the bearing 321. After being connected to the rotating shaft 210 through the bearing 321, no axial offset can occur between the frame 400 and the rotating shaft 210. The rotating shaft 210 can and can only pivot around the axis on the frame 400. At the same time, the stator 100 is fixedly connected to the frame 400. Therefore, after the stator 100 is energized, the magnetic field generated will drive the rotor 200 to rotate. The above are all conventional assembly structures between the rotor 200 and the stator 100. The remaining structures are not described in detail in this application. In order to avoid friction between the rotor 200 and the stator 100 and reduce the damping between the rotor 200 and the stator 100, the side wall of the rotor 200 and the inner wall of the rotating hole 110 are arranged at intervals, so that the side wall of the rotor 200 and the inner wall of the rotating hole 110 are not in direct contact with each other, and no relative friction is generated.

[0032] Similarly, in order to achieve the rotational cooperation between the heating plate 300 and the rotating shaft 210, and to prevent the rotating shaft 210 and the heating plate 300 from having relative displacement in the axial direction, refer to Figure 2 The bottom of the heating plate 300 is provided with a groove 320, and the groove 320 and the through hole 310 are provided correspondingly. The diameter of the groove 320 is larger than the diameter of the through hole 310. A bearing 321 is built into the groove 320, and the heating plate 300 rotates with the bearing 321. Preferably, the axis of the groove 320 and the axis of the through hole 310 are collinear, and the through hole 310 passes through the rotating shaft 210. Therefore, the axes of the groove 320, the rotating shaft 210 and the through hole 310 are all collinear. In order to install the bearing 321 so that the bearing 321 is stably embedded in the groove 320, thereby ensuring that the rotating shaft 210 does not deviate axially in the through hole 310, the side wall of the rotating shaft 210 is provided with an annular placement groove 220, and the placement groove 220 is clamped with a retaining spring 221, and the retaining spring 221 and The bottom of the bearing 321 abuts to cooperate with the groove 320 to press the bearing 321. The retaining spring 221 is clamped in the mounting groove 220, so that the retaining spring 221 cannot be axially offset along the rotating shaft 210. The rotating shaft 210 that cannot be axially offset allows the bearing 321 to be stably embedded in the groove 320. In addition, dimensional errors are prone to occur during the processing process. In order to compensate for the gap caused by the processing dimensional error and ensure that the bearing 321 cannot be offset, a gasket 322 is provided between the bottom surface of the groove 320 and the bearing 321.

[0033] Further, refer to Figure 3 In order to prevent food residues or liquid from falling from the perforation 310 into the above-mentioned mechanical mechanism, a sealing groove 330 is provided at the bottom of the groove 320, and a sealing oil seal 331 is built into the sealing groove 330.

[0034] In some embodiments, at least two connection posts 340 are fixedly connected to the bottom of the heating plate 300, and the ends of the connection posts 340 are provided with overlapping grooves 341, which overlap the outer edge of the upper end of the stator 100 and are fixedly connected to the upper end of the stator 100. The connection posts 340 with overlapping grooves 341 can facilitate the user to overlap the heating plate 300 on the upper end of the stator 100 first, and then fix the connection by welding or other connection methods.

[0035] It should be mentioned that during the long-term operation of the motor, friction will generate heat. At the same time, since the heating plate 300 is directly connected to the rotating shaft 210, the rotating shaft 210 will directly transfer the heat of the heating plate 300. If the temperature is too high, it is easy to cause the entire motor to overload and cycle. For this reason, the rotating shaft 210 is fixedly connected with the heat dissipation fan blade 500. During the pivoting of the rotating shaft 210, the heat dissipation fan blade 500 will rotate with the rotation of the rotating shaft 210, so that the air inside the structure flows, the hot air flows away, and the cold air enters, thereby taking away the heat of the entire motor, ensuring safety while improving the service life. Further, in order to improve the heat dissipation effect, the heat dissipation fan blade 500 is provided with two groups, and the two groups of heat dissipation fan blades 500 are respectively located between the stator 100 and the heating plate 300, and below the stator 100. Each group is provided with a plurality of heat dissipation fan blades 500, and each group of a plurality of heat dissipation fan blades 500 is arranged around the axis of the rotating shaft 210. Heat is dissipated simultaneously from the top and bottom of the stator 100 , and the air along the axial direction of the rotating shaft 210 can be driven, so that the entire air can circulate and flow, and the heat dissipation effect of the fully flowing air is better.

[0036] In summary, integrating the structure of the traditional motor such as the stator 100 and the rotor 200 with the heating plate 300 can reduce the parts to be produced during the production process, reduce the overall cost, and improve the efficiency of processing and assembly.

[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
