The rotation of the main shaft 1 is anticlockwise, and the main shaft is set to have two speeds through a power module: the discharge speed and the washing speed are specifically matched with the detailed description in the following.
2) Power module
Is fixed on the outside of the housing module and cooperates with the main shaft 1 of the agitation module for enabling the agitation module to rotate counterclockwise according to the discharge speed and the washing speed.

the driving gear 10 is fixed on the main shaft 1;
the motor 7 transmits power with the speed reducer 8 through a belt, an output shaft of the speed reducer 8 outputs rotation power through the open speed reduction gear 9, and the open speed reduction gear 9 is meshed with the driving gear 10, so that the output power of the motor 7 is transmitted to the spindle 1 sequentially through the speed reducer 8, the open speed reduction gear 9 and the driving gear 10 to obtain proper speed and protect the motor 7 from reducing impact load.
3) Housing module
The whole body of the shell module is a metal shell 11, a feed inlet 12 is arranged at the top of the metal shell 11, and the feed inlet 12 is arranged above the right side of the relative wheel-shaped frame 2.
