Background

With the continuous improvement of living conditions of people, the food processing machine has become a food cooking appliance with higher daily use frequency. The common cooking machine generally comprises a stirring cup and a base, wherein the base comprises a shell and a motor arranged in the shell, and the motor drives a stirring knife in the stirring cup to rotate at a high speed so as to treat food.

In order to achieve better stirring and crushing effects on food, people continuously refresh the highest rotating speed of the motor by improving the performance of the motor, but the motor rotating at a high speed inevitably generates larger noise and heat. Noise not only affects the user's feeling, but also may cause harm to hearing in severe cases. If the motor heats for a long time, the aging speed of the insulating layer of the motor can be increased, and the power of the motor can be reduced, so that the output rotating speed of the motor is affected, and when the heating is serious, the winding coil can be burnt out, and the service life of the motor can be shortened. For this purpose, a heat radiation fan is also provided in the motor, and the winding coil of the motor is radiated by the heat radiation fan.
