However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

[0026] It should be noted that "axial arrangement" means that the overall arrangement direction is along the axial direction, including but not limited to axial extension, and may be at an angle to the axial direction.

[0027] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0028] like Figures 1-4 As shown, this application discloses a catalytic reaction apparatus. The apparatus includes a housing 1 and a reaction flask 2. The housing 1 has a hollow interior forming a cavity, and an opening at the top for the reaction flask 2 to pass through. The reaction flask 2 can enter the cavity through the opening and can also be removed through the opening. In one embodiment, the opening is located near the top of a side panel of the housing 1. In this embodiment, the opening is located at the top of the housing 1. A cover plate 11 is provided on the housing 1, which can open or close the opening. Furthermore, the cover plate 11 can be made of a high-strength, low-temperature resistant material, ensuring stability and safety under low-temperature and high-pressure environments. The cover plate 11 is connected to the housing via a hinge, allowing for easy opening and closing. Alternatively, it can be connected to the housing via a sliding mechanism.

[0029] The aforementioned catalytic reaction apparatus also includes a light source module 4 for emitting a light source to the reaction vessel 2. A connecting part is provided inside the cavity, and the light source module 4 is detachably connected to the connecting part.

[0030] Understandably, the existence of the connection part allows for the replacement of the light source module 4 according to actual experimental needs, that is, the replacement of light sources with different wavelengths, which can meet the needs of different wavebands in the experiment, that is, it can cover a wider spectral range, ensuring the flexibility and efficiency of the experiment, such as covering the range from deep ultraviolet to terahertz.

[0031] The aforementioned light source module 4 is detachably installed within the cavity. Understandably, this ease of replacement of the light source module 4 allows the catalytic reaction apparatus to more flexibly respond to experimental needs across different wavelengths. That is, it enables rapid replacement of light sources with different wavelengths according to experimental requirements, eliminating the need for constant replacement of the catalytic reaction apparatus, ensuring experimental flexibility and efficiency, and simplifying the operational process. Furthermore, it can meet the specific light source requirements of different types of experiments, expanding the equipment's application range in materials science, chemical reactions, and other fields.

[0032] A horizontally arranged support plate 14 is provided inside the cavity, and a connecting part is provided on the support plate 14. In one embodiment, the connecting part is a snap-fit ​​that engages with the light source module 4. In this embodiment, the connecting part is a slot 141, and the bottom of the light source module 4 is inserted into the slot 141 with a plug-in part 410. The plug-in method makes the assembly and disassembly of the light source module 4 more convenient and quick.

[0033] The aforementioned light source module 4 includes a housing 41 and LEDs. A cavity is formed inside the housing 41, and the LEDs are located within the cavity. Through holes 411 for the light source to pass through are distributed on the sidewalls of the housing 41. The aforementioned connector 410 is located on the housing 41. In this embodiment, the light source module 4 has multiple LEDs. The aforementioned catalytic reaction apparatus also includes a control system for individually controlling the light intensity and wavelength of each LED, and the control system is electrically connected to the LEDs. It is understood that the aforementioned control system can precisely adjust the exposure time and light intensity of each LED at different wavelengths, better meeting the needs of actual experiments. Furthermore, it improves the controllability and accuracy of the experiment, and is particularly suitable for complex, multi-stage photocatalytic reactions.

[0034] like Figures 2-4 As shown, a container 5 is provided inside the cavity, and a storage chamber is formed inside the container 5. The reaction bottle 2 is placed inside the storage chamber, and the light source module 4 is located outside the storage chamber. In this way, the reaction bottle 2 can be conveniently placed while being illuminated.

[0035] There are two sets of light source modules 4, which are arranged at intervals along the first direction, and the container 5 is located between the two sets of light source modules 4. In this way, the reaction flask 2 inside the container 5 can be illuminated more comprehensively.

[0036] like Figures 2-4 As shown, there are multiple containers 5, arranged at intervals along a second direction, which intersects the first direction. In this embodiment, the first and second directions are perpendicular, such as the first direction being left-right and the second direction being front-back. Multiple containers 5 can be arranged to form multiple temperature zones, and a single catalytic reaction device can achieve reactions in different temperature zones, better meeting the needs of experimenters.

[0037] like Figure 2 and Figure 3As shown, the container 5 is equipped with a coolant pipe 51 for supplying coolant to the container chamber and a drain pipe 52 for discharging liquid from the container chamber. Both the coolant pipe 51 and the drain pipe 52 are connected to the container chamber. The housing 1 is provided with an inlet 134 connected to the coolant pipe 51 and a drain outlet 135 connected to the drain pipe 52. Both the inlet 134 and the drain outlet 135 are connected to a cooling device. The cooling device is located outside the reaction equipment.

[0038] Understandably, the presence of the coolant pipe 51 allows for the sequential delivery of coolant into the containment chamber via the inlet 134 and the coolant pipe 51, increasing convenience. The coolant flows into the containment chamber through the inlet 134 and the coolant pipe 51, ensuring that the reaction flask 2 is under stable low-temperature conditions. Furthermore, after the experiment, the liquid in the containment chamber can be discharged sequentially through the drain pipe 52 and the drain port 135, facilitating drainage. Understandably, when the coolant circulates through the inlet 134 and the drain port 135, the controller inside the catalytic reaction device precisely adjusts the coolant temperature according to the set experimental parameters, ensuring that the environment inside the reaction flask 2 remains at a low temperature. For example, during high-temperature photocatalytic reactions, the coolant effectively controls the temperature of the reaction flask 2, preventing overheating and ensuring that the catalytic reaction device can operate stably at temperatures up to 200°C, while also supporting low-temperature experimental conditions (such as down to -30°C). This means a wide temperature control range and that the internal temperature of the catalytic reaction device remains stable during the experiment, avoiding interference from high or low temperatures on the experimental results. In addition, the cooling system formed by the aforementioned cooling device, inlet, coolant pipe, drain pipe, and drain outlet maintains a constant temperature in the reaction environment, thus improving the reliability of the experimental results.

[0039] In addition, the containment chamber is equipped with upward-facing mounting slots for placing reaction flasks 2; there are multiple mounting slots. 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. Multiple reaction flasks 2 arranged in the same area support simultaneous execution of multiple sets of experiments. The aforementioned control system can precisely adjust the light intensity and wavelength required for each reaction flask 2, ensuring the efficient conduction of the photocatalytic reaction.

[0040] like Figure 1 As shown, the top of the aforementioned container is covered with a baffle 6, which has a positioning hole for the reaction flask 2 to pass through. It is understood that the positioning hole helps to position the reaction flask 2, effectively preventing displacement or damage during subsequent stirring and vibration, thus ensuring the safety and stability of the experimental process. The baffle 6 is made of the same material as the housing 1, possessing good fire and explosion-proof properties.

[0041] Reaction flask 2 is equipped with a stirrer, such as... Figure 3 and Figure 4As shown, a magnetic stirring motor 8 is installed inside the cavity below the container 5 to drive the stirring components. Each container 5 has a magnetic stirring motor 8 located below it, and the magnetic stirring motor 8 drives the stirring components to stir.

[0042] Understandably, the magnetic stirrer 8 uses magnetic force to drive the stirring element inside the reaction flask 2 for uniform mixing. The speed of the stirrer motor can be precisely adjusted via the control panel 7 or remote operation. The stirring rate is adjustable from 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 stirrer 8 can be used.

[0043] The aforementioned magnetic stirrer motor 8, through non-contact magnetic transmission, avoids the wear and contamination caused by traditional mechanical stirring methods to the catalytic reaction device, thus improving the reliability and durability of the equipment. The low-noise design of the magnetic stirrer motor 8 allows it to maintain a quiet laboratory environment while operating efficiently. During the experiment, the coolant pipe 51 and the magnetic stirrer motor 8 can remain running continuously to ensure stable temperature and thorough mixing.

[0044] like Figure 3 and Figure 4 As shown, the housing 1 has a receiving chamber 15 located below the receiving box 5. The magnetic stirring motor 8 is located inside the receiving chamber 15. The housing 1 includes an outer peripheral plate 16 located around the receiving chamber 15. The outer peripheral plate 16 includes a surrounding plate 161 and a side cover plate 162. The surrounding plate 161 has an opening that communicates with the receiving chamber 15. The side cover plate 162 is detachably installed at the opening to open or close the opening.

[0045] Understandably, the presence of the receiving chamber 15 facilitates the housing of the aforementioned magnetic stirring motor 8 while increasing the storage space for other components, and also protects the components within the receiving chamber 15. The side cover 162 is removable, facilitating maintenance and repair of the components within the receiving chamber 15.

[0046] The aforementioned enclosure 1 includes a front wall panel 12 located in front of the side cover panel 162. 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 7. The lower panel 122 is part of the enclosure panel 161. The viewing window 1211 allows the experimenter to observe the reaction in real time and remotely monitor the experimental progress through the control panel 7 or a mobile device. The control panel is designed to be waterproof and dustproof to ensure safe and stable operation during the experiment.

[0047] like Figure 2As shown, the enclosure 1 is equipped with a control switch 131, a temperature interface 132, and a communication interface 133 for data transmission. In one embodiment, the control switch 131, temperature interface 132, and communication interface 133 are located on different wall panels of the enclosure 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 enclosure 1. In this embodiment, the enclosure 1 includes a rear panel 13 located behind the front wall panel 12, and 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 may 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.

[0048] 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 catalytic reaction unit, ensuring complete power disconnection when the unit is not in use through physical power off, thus avoiding energy waste and improving the safety of the catalytic reaction unit. Before the experiment begins, the user must use this control switch 131 to provide power to the catalytic reaction unit to ensure the normal operation of each subsystem.

[0049] Power connector 136 supports 220V or 110V power supply, ensuring the versatility of the catalytic reaction device 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.

[0050] 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 remotely control the experimental process and view data in real time 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.

[0051] Temperature interface 132 is used to connect an external temperature sensor to ensure accurate monitoring of the temperature inside reaction flask 2. Temperature interface 132 is a temperature probe interface, enabling the catalytic reaction apparatus to precisely monitor temperature changes inside the reaction flask and ensure accurate temperature control during the experiment.

[0052] Furthermore, experimental data can be viewed in real time via the communication interface 133, 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.

[0053] 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.

[0054] 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.
