[0028] like Figures 1 to 4 As shown, this application provides a reaction apparatus. The reaction apparatus includes a housing 1, a reaction flask 2, and a temperature measuring element 3 for detecting the temperature inside the reaction flask 2. The signal output terminal of the temperature measuring element 3 is electrically connected to a controller. The housing 1 has a hollow interior forming a cavity, and the housing 1 has an opening 101 for the reaction flask 2 to pass through. That is, the reaction flask 2 can enter the cavity through the opening 101, and can also be removed through the opening 101. In one embodiment, the opening 101 is located near the top of the side plate of the housing 1. In this embodiment, the opening 101 is located on the top plate 10 of the housing 1. The housing 1 is provided with a cover plate 11 that can open or close the opening 101. The presence of the opening 101 facilitates the replacement, addition, or sampling of the reaction flask by the experimenter at different stages. In addition, a sealing element is provided on the inner side of the cover plate 11 to ensure the airtightness of the cover plate and the periphery of the opening 101 when the opening 101 is closed, so as to avoid gas or liquid leakage and ensure the safety of the experiment.

[0029] In addition, the cover plate 11 can be made of high-strength, low-temperature resistant materials, ensuring stability and safety under low-temperature and high-pressure environments. The cover plate 11 is connected to the enclosure via hinges, allowing for easy opening and closing. Alternatively, it can be connected to the enclosure via a sliding mechanism.

[0030] like Figure 2As shown, the aforementioned housing 1 is provided with an inlet 134 for supplying coolant into the cavity and an outlet 135 connected to the cavity. Both the inlet 134 and the outlet 135 are used to connect to a cooling device. The cooling device is a cooling device installed outside the reaction apparatus.

[0031] Understandably, the temperature sensor 3 can detect the temperature inside the reaction flask 2 in real time and feed the data back to the device's controller to ensure accurate temperature control. When the coolant in the cooling device circulates continuously through the inlet and outlet, it ensures that the reaction flask 2 is kept in a low-temperature environment. The controller inside the reaction device precisely adjusts the temperature of the coolant according to the set experimental parameters, ensuring that the environment inside the reaction flask 2 remains at a low temperature. It also achieves a wide temperature control range, such as -30℃ to 100℃, greatly expanding the applicability of the reaction device. This makes it suitable for experiments requiring low-temperature environments, such as low-temperature catalytic reactions or the synthesis of special materials, solving the technical problem that the temperature control range in existing technologies cannot meet the needs of complex low-temperature experiments.

[0032] In addition, the aforementioned temperature measuring element 3 can be a temperature measuring probe or a sensor capable of measuring temperature.

[0033] The reaction vessel 2 mentioned above is made of high-pressure heat-resistant material and can withstand an internal pressure of up to 100 atmospheres, making it suitable for various high-temperature and high-pressure reaction conditions.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, a container 4 is provided inside the cavity, and a storage chamber is formed inside the container 4. The reaction flask 2 is placed inside the storage chamber, and the temperature measuring element 3 is placed on the container 4. It can be understood that the presence of the container 4 facilitates the placement of the reaction flask 2.

[0035] like Figure 4 As shown, the containment chamber is equipped with multiple upward-facing mounting slots for placing reaction flasks 2. It is understood that a single containment chamber can hold multiple reaction flasks 2, and the user can select the number of reaction flasks 2 to place according to actual needs. Furthermore, multiple reaction flasks 2 arranged in the same area support simultaneous execution of multiple sets of experiments.

[0036] The aforementioned container 4 is equipped with a coolant pipe 41 connecting the container chamber and the inlet 134, and a drain pipe 42 for discharging liquid from the container chamber. The drain pipe 42 is connected to the drain outlet 135. It is understood that the presence of the coolant pipe 41 allows coolant to be sequentially supplied to the container chamber via the inlet 134 and the coolant pipe 41, while the liquid in the container chamber can be sequentially discharged through the drain pipe 42 and the drain outlet 135, thus achieving coolant circulation. The coolant flows into the container chamber through the inlet 134 and the coolant pipe 41, ensuring that the reaction flask 2 is under stable low-temperature conditions. In one embodiment, the coolant pipe 41 and the drain pipe 42 are arranged side-by-side. In this embodiment, the coolant pipe 41 is located below the drain pipe 42.

[0037] Multiple container boxes 4 are provided, allowing for the arrangement of multiple temperature zones. A single reaction device can achieve reactions in different temperature zones, better meeting the needs of the experimenter. In this embodiment, four container boxes 4 are used. Alternatively, two, three, or more can be used. Each container box 4 corresponds to a temperature measuring element 3. The temperature measuring element 3 is connected to the experimental area (i.e., the container chamber) where the reaction flask 2 is located. Each temperature measuring element 3 can detect the temperature inside the reaction flask 2 in its corresponding experimental area in real time and feed the data back to the controller to ensure accurate temperature control. Through the distribution of multiple temperature measuring elements 3, the device can achieve independent temperature control in multiple temperature zones, thereby meeting the experimental needs of different reaction flasks 2 with varying temperature requirements. Users can set different temperature conditions for different reaction flasks 2 according to experimental requirements.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, a magnetic stirring motor 7 is installed below each container 4. A stirring element is installed inside the reaction flask 2, and the magnetic stirring motor 7 drives the stirring element to stir. In this embodiment, the magnetic stirring motor 7, which drives the stirring element, is installed inside the housing 1 at a position below the container 4. It can be understood that the magnetic stirring motor 7 drives the stirring element inside the reaction flask 2 to perform uniform stirring through magnetic force. The speed of the stirring motor can be precisely adjusted via a control panel or remote operation. The stirring rate is adjustable within the range of 0 to 1000 rpm, ensuring uniform mixing of liquids of different viscosities, improving reaction efficiency, and achieving ideal reaction results. It is suitable for various experimental scenarios, ensuring uniform mixing of reactants within the reaction flask 2 and improving reaction efficiency. Furthermore, for liquids with very high viscosity, a more powerful magnetic stirring motor 7 can be used.

[0039] The aforementioned magnetic stirring motor 7, through non-contact magnetic transmission, avoids the wear and contamination caused by traditional mechanical stirring methods on the experimental apparatus, thus improving the reliability and durability of the equipment. The low-noise design of the magnetic stirring motor 7 allows it to maintain a quiet laboratory environment while operating efficiently.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, a receiving chamber 14 is provided below the receiving box 4 inside the cavity. The magnetic stirring motor 7 is located inside the receiving chamber 14. The box body 1 includes an outer peripheral plate 15 located at least partially around the receiving chamber 14. The outer peripheral plate 15 includes a surrounding plate 151 and a side cover plate 152. The surrounding plate 151 has an opening that communicates with the receiving chamber 14. The side cover plate 152 is detachably installed at the opening to open or close the opening.

[0041] Understandably, the presence of the receiving chamber 14 facilitates the housing of the aforementioned magnetic stirring motor 7 while increasing the storage space for other components, and also protects the components within the receiving chamber 14. The side cover 152 is removable, facilitating maintenance and repair of the components within the receiving chamber 14.

[0042] like Figure 1 As shown, the aforementioned housing 1 includes a front wall panel 12 located in front of the side cover panel 152. The front wall panel 12 includes at least an upper panel 121 and a lower panel 122 arranged sequentially from top to bottom. The upper panel 121 is equipped with a viewing window 1211 for easy observation, and the front surface of the lower panel 122 is provided with a control panel 6. The control panel 6 is at least partially located above the side cover panel 152. In this embodiment, the control panel 6 is located above the side cover panel 152.

[0043] Understandably, the existence of the aforementioned window 1211 allows researchers to observe the reaction progress at any time. The control panel features a waterproof and dustproof design to ensure safe and stable operation during the experiment.

[0044] In addition, such as Figure 1 and Figure 4 As shown, the top of the aforementioned container 4 is covered by a baffle 5, meaning the top of the container is open. The baffle 5 has a positioning hole 51 for the reaction flask 2 to pass through. It is understood that the presence of the positioning hole 51 allows the reaction flask 2 to be positioned, effectively preventing displacement or damage during subsequent stirring and vibration, thus ensuring the safety and stability of the experimental process.

[0045] The baffle 5 is made of the same material as the housing 1, and has good fireproof and explosion-proof performance.

[0046] like Figure 2 and Figure 3As shown, the housing 1 is equipped with a control switch 131, a temperature interface 132, and a communication interface 133 for data transmission. The temperature interface 132 is electrically connected to the temperature measuring element 3, thus serving as the interface for the temperature probe. In one embodiment, the control switch 131, temperature interface 132, and communication interface 133 are located on different wall panels of the housing 1. In another embodiment, the control switch 131, temperature interface 132, and communication interface 133 are all located on the side wall panels of the housing 1. In this embodiment, the housing 1 includes a rear panel 13 located behind the front wall panel 12. The control switch 131, temperature interface 132, liquid inlet 134, and communication interface 133 are all located on the rear panel 13. The control switch 131 can be located on the left or right side of the rear panel 13. The rear panel 13 is also equipped with a power connector 136.

[0047] Understandably, control switch 131 is used to control the opening and closing of the equipment. This control switch 131 directly controls the power supply to the entire reaction apparatus, ensuring complete power disconnection when the apparatus is not in use through physical power off, avoiding energy waste and improving the safety of the reaction apparatus. Before the experiment begins, the user needs to provide power to the reaction apparatus via this control switch 131 to ensure the normal operation of each subsystem.

[0048] Power connector 136 supports 220V or 110V power supply, ensuring the versatility of the reaction apparatus in different laboratory environments. Power connector 136 also features overload protection, automatically cutting off power in case of excessive current or internal faults, preventing damage to power connector 136.

[0049] The aforementioned communication interface 133 includes at least one of a USB interface, a network interface, and a sensor interface. In this embodiment, the communication interface 133 includes a USB interface, a network interface, and a sensor interface. The USB interface is used to connect to a local computer or data storage device, facilitating the download and storage of experimental data. The network interface supports remote monitoring and operation of the device via a local area network or the Internet. Users can achieve real-time remote control and data viewing of the experimental process by connecting a mobile device or computer. The sensor interface connects to external sensors or expansion devices to enhance the monitoring capabilities of the laboratory environment, such as the access of external temperature, pressure, or humidity sensors.

[0050] Furthermore, experimental data can be viewed in real time via the 133 communication interface, and temperature or other experimental parameters can be remotely adjusted to ensure the accuracy and efficiency of the experimental process. Simultaneously, it ensures that experimental conditions are always optimal. This precise control significantly reduces human intervention and error, improves the repeatability and accuracy of the experiment, and overcomes the lack of real-time intelligent monitoring and automated control in existing technologies.

[0051] Temperature interface 132 is used to connect an external temperature sensor to ensure accurate monitoring of the temperature inside reaction flask 2. The reaction apparatus supports the simultaneous operation of multiple temperature sensors 3 to enable independent temperature monitoring of different reaction flasks 2, ensuring the realization of multi-temperature zone temperature control.

[0052] When the above-mentioned reaction apparatus is started, the experimenter sets the experimental parameters through the control panel. The internal controller of the reaction apparatus independently controls the temperature of each reaction flask 2 according to the set values ​​via the internal temperature measuring element 3. A magnetic stirring motor 7 is installed below the experimental area, and the stirring speed can be adjusted according to experimental needs to ensure thorough mixing of the reactants. All data during the experiment, including temperature, stirring speed, and reaction progress, are fed back to the controller in real time through sensors to ensure precise control and recording during the experiment. After the experiment is completed, the experimental data can be remotely replayed via a mobile device, and the experimental results can be analyzed using the digital twin function inside the reaction apparatus.

[0053] The above-mentioned reaction device integrates multi-temperature zone independent temperature control, coolant pipe 41, temperature measuring element 3 and magnetic stirring motor 7, which better meets experimental needs and greatly improves the working efficiency and flexibility of the laboratory.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
