[0002] Common traditional electric heating mantles mainly consist of a resistance wire heating element, a fiberglass insulation layer, and a potentiometer adjustment device. Heating is achieved by the current flowing through the resistance wire, which generates heat. The ordinary insulation layer reduces heat loss, and the voltage is adjusted via a potentiometer to control the temperature.

[0003] Existing heating mantles only have a heating function and use resistance wire heating, which has high thermal inertia, is prone to overheating when controlled by potentiometers, and has large temperature fluctuations, making it difficult to meet the requirements of high-precision experiments. At the same time, there is no heat dissipation component, and when the temperature inside the reaction vessel is high, it can only rely on natural heat dissipation, which is slow, easily damages components, and affects the sample.

[0004] Existing electric heating mantles require a separate stirrer for mixing, which takes up a lot of space and requires manual stirring, making the operation cumbersome. Utility Model Content

The support mold 1 is used to place a reaction vessel. The magnetic stirring assembly includes a magnetic stirring power component disposed inside the support mold 1 and a stirring magnet disposed inside the support mold 1. Driven by the magnetic stirring assembly, the stirring magnet moves to stir the object inside the reaction vessel. Specifically, the magnetic stirring power component includes a high-performance rare-earth permanent magnet and an intelligent frequency conversion drive circuit. After being energized, the high-performance rare-earth permanent magnet is used to drive the movement of the stirring magnet to generate a stirring force. The magnetic stirring assembly drives the stirring magnet to stir using magnetic circuit drive technology. The magnetic circuit drive technology mentioned here uses a high-performance rare-earth permanent magnet and is controlled by an intelligent frequency conversion drive circuit. This technology utilizes permanent magnets to construct a magnetic circuit, and the intelligent frequency conversion drive circuit precisely adjusts the current magnitude and frequency, so that the magnetic fields cooperate and work synergistically. The magnetic circuit can be a single, dual, or triple magnetic circuit. This embodiment uses a triple magnetic circuit, which allows for more flexible and precise control of the magnetic field strength and direction compared to single or dual magnetic circuits.

To improve heat dissipation efficiency, a first heat dissipation hole 5 is provided on the insulation layer 4, penetrating the insulation layer 4 to allow air to flow between the carbon nanotube heating element, the insulation layer 4, and the shell 3. A covering assembly is provided on one side of the insulation layer 4, at least to cover the first heat dissipation hole 5 to prevent air from flowing between the carbon nanotube heating element, the insulation layer 4, and the shell 3.

In this embodiment, the temperature detection component includes a temperature sensor connected to a control mechanism. When the temperature sensor detects that the temperature inside the reaction vessel is lower than a preset value, it sends a signal to the control mechanism, which then controls the carbon nanotube heating element to heat the vessel. When the temperature sensor detects that the temperature inside the reaction vessel is lower than the preset value, it sends a signal to the control mechanism, which then controls the first driving component to drive the cover plate 6 away from the insulation layer 4, exposing the first heat dissipation hole 5. Simultaneously, the control mechanism controls the air blower mechanism 7 to open, accelerating airflow and improving cooling efficiency. The timing of opening the first heat dissipation hole 5 and the air blower mechanism 7 is set according to actual needs.
