It is recorded in the text that "when in use, solid particle drugs and a dissolving agent can be injected into the inside of the mixing box body. At this time, the solid particle drugs are not dissolved evenly, and part of them are deposited at the bottom of the mixing box body. By driving the first stirring mechanism to work through the first driving mechanism, the solid particle drugs can be dissolved faster. By driving the second stirring mechanism to work through the second driving mechanism, the solid particle drugs deposited at the four corners of the inner bottom of the mixing box body can be dissolved faster. The first stirring mechanism and the second stirring mechanism can make the drug dissolve more evenly, reduce the dead corners caused by drug deposition, and improve the drug use efficiency.
