[0023] As Figure 1 , Figure 2 and Figure 3 shown, the rotating component 31 includes an electric push rod 311 fixedly connected to the upper end of the liquid storage cabinet 1, the telescopic end of the electric push rod 311 is rotatably connected with a rotating shaft 312, the lower end of the rotating shaft 312 is fixedly connected with a square shaft 317, the surface of the square shaft 317 is slidably connected with a square hole pipe 318, the surface of the square hole pipe 318 is rotatably connected with a fixed pipe 315, the fixed pipe 315 is fixedly connected to the inner bottom wall of the liquid storage cabinet 1, the surface of the rotating shaft 312 is fixedly connected with a connecting frame 313, the lower end of the connecting frame 313 is fixedly connected with a plurality of placing baskets 314, the surface of the fixed pipe 315 is fixedly connected with a plurality of partition boards 316, and a liquid medicine bin is formed between adjacent partition boards 316;

[0024] During the use process, the square hole tube 318 can be driven by the motor 33 to rotate. Under the cooperation of the square hole tube 318 and the square shaft 317, the rotating shaft 312 rotates synchronously. The rotation of the rotating shaft 312 drives multiple placement baskets 314 to rotate synchronously through the connecting frame 313. Before the placement basket 314 rotates, the driving electric push rod 311 can be used to drive the rotating shaft 312 to move upward, so that the placement basket 314 moves upward and then rotates, moving the objects inside the placement basket 314 from one liquid medicine tank to another liquid medicine tank for soaking.

[0025] As Figure 1 , Figure 2 and Figure 4 shown, the mixing assembly 32 includes multiple rotating rods 322 located below the liquid medicine tank.
