A heating rod 12 is fixedly sleeved on the inner circular wall of the heating tank 11. The connecting column 6 is fixedly sleeved on the inner circular wall of the heating tank 11. The heating rod 12 is electrically connected to the PLC controller 3. When the operator prepares the eye drops through the preparation tank 2, the eye drop concentrate is placed inside the preparation tank 2. Then, the PLC controller 3 starts the servo motor 5. The drive shaft of the servo motor 5 rotates, which drives the connecting column 6, the rotating column 7 and the stirring plate 8 to rotate. Then, the rotation of the stirring plate 8 facilitates the stirring of the eye drop concentrate. When it is necessary to heat the eye drop concentrate, the PLC controller 3 controls the heating rod 12 to start. The heating rod 12 will generate high temperature, which will then heat the rotating column 7. Since the rotating column 7 is surrounded by the eye drop concentrate, the temperature of the rotating column 7 will diffuse outward after the surface temperature rises. Then, the high temperature will start from the center of the eye drop concentrate, which facilitates the heating and preparation of the eye drops.

With the rotation of the rotating column 7 and the stirring plate 8, the container 2 is easily cleaned. A discharge hole 22 is opened on the outer circular wall of the container 2, and a discharge valve 23 is fixedly fitted onto the inner circular wall of the discharge hole 22.
[0026] Example 3
[0027] Based on the above embodiment 1 or 2, refer to Figure 1 , Figure 2 and Figure 5 The top surface of the preparation tank 2 is provided with a feeding hole 24. A feeding pipe 25 is fixedly sleeved on the inner circular wall of the feeding hole 24. A sealing block 26 is movably sleeved on the inner circular wall of the feeding pipe 25.

[0028] Working principle: Please refer to Figures 1-5As shown, through the prepared container 2, when the staff prepares the eye drops, they put the eye drop concentrate into the container 2, and then start the servo motor 5 using the PLC controller 3. The drive shaft of the servo motor 5 rotates, which drives the connecting column 6, the rotating column 7 and the stirring plate 8 to rotate. The rotation of the stirring plate 8 facilitates the stirring of the eye drop concentrate. When it is necessary to heat the eye drop concentrate, the heating rod 12 is started using the PLC controller 3. The heating rod 12 generates high temperature, which heats the rotating column 7. Since the rotating column 7 is surrounded by the eye drop concentrate, the temperature on the surface of the rotating column 7 rises and diffuses outward, so the high temperature starts to heat from the center of the eye drop concentrate, thus facilitating the heating and preparation of the eye drops.
[0029] With the water storage tank 13 in place, the staff can put water into the water storage tank 13. When the staff needs to clean the inside of the preparation tank 2, the micro submersible pump 14 is started by using the PLC controller 3. The micro submersible pump 14 will then draw the water from the water storage tank 13 into the annular pipe 18 through the connecting pipe 16, and then discharge it through the nozzle 21. The water discharged through the nozzle 21 will flow downward through the inner wall of the preparation tank 2. With the rotation of the rotating column 7 and the stirring plate 8, it is convenient to clean the preparation tank 2.
