[0038] Please see Figures 1-6 Example 1: This utility model provides the following technical solution: a thermal experimental reaction device with precise temperature control, including a base 1 and a reaction chamber 2. The reaction chamber 2 is located inside the base 1.

[0039] The heating power of the uniform heating mechanism can be adjusted by the temperature controller 3, thereby adjusting the subsequent reaction temperature. The uniform heating mechanism heats the water in the water bath 8 and then heats the reaction chamber 2, making the reaction chamber 2 heated evenly. The sealing mechanism can seal the reaction chamber 2 to maintain the stability of the reaction environment.

[0040] Example 2: Based on Example 1, a sealing mechanism is disclosed, including a sealing cover 4, a support frame 6, and a control rod 7. The sealing cover 4 is disposed above the reaction chamber 2, the support frame 6 is fixed above the base 1, and the sealing cover 4 and the support frame 6 form an up-and-down sliding structure. The control rod 7 is rotatably mounted above the sealing cover 4, and the control rod 7 and the support frame 6 form a threaded connection. A temperature sensor 5 is installed below the sealing cover 4 to monitor the temperature inside the reaction chamber 2. The uniform heating mechanism includes a first heater 9 and a second heater 10. The first heater 9 is evenly distributed on the outside of the reaction chamber 2, and the second heater 10 is disposed below the reaction chamber 2.

[0041] The water in the water bath 8 is heated evenly by the first heater 9 and the second heater 10. When it is necessary to close the reaction chamber 2, the control rod 7 can be rotated so that the control rod 7 can drive the sealing cover 4 to move through the threaded connection between the control rod 7 and the support frame 6, so that the sealing cover 4 moves downward to close the reaction chamber 2.

[0042] Example 3: Based on Example 1, a drainage mechanism is disclosed, including an overflow pipe 12, a first one-way valve 13, a collection box 14, and a positioning ring 15.

The first one-way valve 13 is installed inside the overflow pipe 12, and the conduction direction of the first one-way valve 13 is from the inside of the water bath 8 to the outside of the water bath 8. The collection box 14 is located below the overflow pipe 12. The positioning ring 15 is located on the outside of the collection box 14 to position the collection box 14. The water replenishment mechanism includes a connecting pipe 16, a second one-way valve 17, a replenishment chamber 18, a movable plug 19, a control frame 20, and an electric push rod 21.

[0043] When cooling control is required, the control frame 20 can be moved by the electric push rod 21. The control frame 20 drives the movable plug 19 to move downward, pushing out the water in the replenishment chamber 18. The water flows through the connecting pipe 16 and the second one-way valve 17 along the replenishment port 11 into the water bath 8. The water in the water bath 8 flows out into the collection box 14 through the overflow pipe 12 and the first one-way valve 13, thereby cooling the water and achieving cooling control of the water. This avoids the difficulty in adjusting the temperature in the reaction chamber 2 due to the insulation properties. Subsequently, by controlling the movable plug 19 to move upward, the suction pipe 22 can draw water from the outside to replenish the water in the replenishment chamber 18.
