In real life, people can use a wall breaking machine to make fluid drinks, the wall breaking machine breaks cell walls of food materials through high-speed operation of processing execution parts such as blades and the like driven by a motor to obtain fluid drinks with fine taste, people can also use a noodle maker, and noodle stirring rods driven by the motor in the noodle maker run at low speed to automatically knead noodles, in the process, people face the difficult problem that the wall breaking machine running at high speed cannot be suitable for heavy-load dough kneading function, or the wall breaking machine is also used, when the wall breaking machine stirs viscous food materials, because the existing mechanism usually adopts electronic speed regulation, the output torque of the motor is extremely low at low speed and is not smooth during heavy-load running, the beating effect of the viscous food materials still needs to be improved, and because the functions of electric appliances are single, in order to meet the use requirements of people, people need many electrical appliances. In addition, for some schemes with additional gear transmission components, although speed increase/speed reduction can be realized, the effect of high and low speed compromise cannot be realized because the transmission ratio is a fixed value, because we know that in some food material processing processes, high and low speed whipping can make the mixing effect better.

In order to solve the problems and bring convenience to the life of people, the application provides a food processor 2.

Fig. 7 to 8 show that the number of the second output shafts 70 is 1, and fig. 9 shows that the number of the second output shafts 70 is 2, but the number of the second output shafts 70 may also be 3 or other values according to the requirement of the present disclosure. The motor shaft 13 is in transmission connection with the transmission component 20, wherein the motor assembly 1 can be switched between a first working state and a second working state when the motor shaft 13 rotates in different directions, the first working state is that the motor shaft 13 drives the first output shaft 40 to rotate independently through the transmission component 20, the second working state is that the motor shaft 13 drives the first output shaft 40 and the second output shaft 70 to rotate together, wherein the torque of the first output shaft 40 in the first working state is different from the torque of the second working state, specifically, the motor assembly 1 has a first working state that the transmission component cuts off the power transmission between the first output shaft 40 and the second output shaft 70 when the motor shaft 13 rotates in the first direction, the motor shaft 13 drives the first output shaft 40 to rotate through the transmission component, and when the motor shaft 13 rotates in the direction opposite to the first direction, and a second working state that the motor shaft 13 drives the first output shaft 40 and the second output shaft 70 to rotate together through the transmission component, wherein the torque of the first output shaft 40 when the motor assembly 1 is in the second working state is different from the torque of the motor assembly 1 when the motor assembly 1 is in the first working state.

The material and shape of the first and second housings are not limited in the present application as long as they are suitable for the overall structural strength and can accommodate the components such as the input rotator 30 and the follower 60 therein. The present application prefers that the housing 20a and the first end cap 11 are detachably engaged, which is convenient in the assembling process. Further, in order to facilitate the integral installation of the motor assembly 1 into the electric appliance to which the motor assembly is applied, in an embodiment, a connecting portion may be further disposed on the first end cover 11, and the connecting portion may be located on the first end cover 11 and/or the housing 20a, and in an implementation manner, the connecting portion is provided with a connecting hole, so that the motor assembly 1 may be integrally assembled into the internal environment of the electric appliance to which the motor assembly is applied by a connecting member, such as a screw or a bolt.
