[0031] The regulating and stirring assembly 2 also includes a pump body 205, a medicine storage box 206 and a driving motor 207;

[0032] A driving motor 207 is fixedly installed on the top of the spiral feed shaft 209, and the driving motor 207 is electrically connected to the output end of an external power supply, so as to fully mix and stir the raw materials and scrape off the raw materials attached to the inner wall of the mixing barrel 202 to avoid waste.
