[0004] The medicine mixing barrel in the above technology has the following disadvantages when mixing medicine: 1. When adding powdered medicine, the medicine tends to float on the liquid surface of the medicine mixing barrel and is not easy to quickly mix with the liquid in the medicine mixing barrel, which reduces the work efficiency; 2. The bottom of the medicine mixing barrel cannot be stirred, which easily causes the medicine to precipitate at the bottom of the medicine mixing barrel, making the mixing effect worse. Therefore, there is room for improvement. Utility Model Content
