After the reaction is completed, the rotating motor and the battery are turned off, the first valve and the second valve are opened, and ice water with the required working temperature is pumped into the circulating water pump through the connecting pipe, the outside of the connecting pipe is connected to the water source, and the circulating water pump adds water to the water tank through the water inlet pipe. After the reaction is completed, the first valve is closed, and the water in the water tank is discharged from the outlet pipe through the connecting pipe, and the temperature probe of the temperature controller is extended into the reaction barrel to monitor the temperature in real time;

[0004] The above device has some problems. The device is cumbersome to use, and continuous heating by the heating wire during the reaction may lead to poor reaction effect. The reaction temperature cannot be controlled, and the effect of use is poor.

[0005] Therefore, we proposed a quantum dot preparation device with temperature control function to solve the above problems. Utility Model Content
