[0037] Please see Figures 1 to 6 To better understand the microreactor 10 of this application, the following further explanation of the microreactor 10 is provided:

[0038] One embodiment of the micro reactor 10 includes a stirring mechanism 100, a reactor body 200, a temperature control component 300, and a heating and cooling component 400. The reactor body 200 has a reaction chamber 201 for containing reactants. The stirring end of the stirring mechanism 100 extends into the reaction chamber 201 to rotate and stir the reactants. The temperature control component 300 includes a temperature control box 310 and a control panel 320. The reactor body 200 is disposed within the temperature control box 310, and a thermally conductive liquid channel 301 is formed between the temperature control box 310 and the reactor body 200 for holding a heat-conducting liquid. The heating and cooling component 400 includes an electric heating element 410 and a heat dissipation element. The heat sink 420 and the thermoelectric cooler 430 are installed at the bottom of the temperature control box 310. The heat sink 420 is distributed along the outer peripheral wall of the temperature control box 310. The thermoelectric cooler 430 is installed inside the box wall of the temperature control box 310. The cold end of the thermoelectric cooler 430 faces the inner wall of the temperature control box 310, and the hot end of the thermoelectric cooler 430 faces the outer wall of the temperature control box 310. The electric heating element 410 and the thermoelectric cooler 430 are electrically connected to the control panel 320.

[0039] In this embodiment, the control panel 320 controls the electric heating element 410 to heat the heat-conducting liquid in the heat-conducting liquid channel 301, and the heat-conducting liquid transfers heat to the reactor body 200, achieving the effect of uniformly heating the reactants in the reaction chamber 201. A thermoelectric cooler 430 is embedded inside the wall of the temperature control chamber 310, with its hot end facing the outer wall and its cold end facing the inner wall. Thus, the control panel 320 controls the operation of the thermoelectric cooler 430, accelerating the transfer of heat from the cold end to the hot end of the thermoelectric cooler 430, ultimately transferring the heat to the heat dissipation fins 420 on the outer wall of the temperature control chamber 310 for effective heat dissipation. The micro reactor 10 of this invention combines heating and cooling effects, and can effectively integrate the electric heating element 410 and the semiconductor cooling chip 430 into a structural design, so that the micro reactor 10 has a good compactness and reduces the footprint of the micro reactor 10.

[0040] It should be noted that in this embodiment, the electric heating element 410 adopts the principle of heating by passing an electric heating wire. The electric heating element 410 is existing technology and will not be described in detail here.

[0041] It should be noted that the thermoelectric cooler 430 has the function of accelerating the conduction of heat from the cold end to the hot end during the power-on process, and the thermoelectric cooler 430 is existing technology, so it will not be described in detail here.

[0042] like Figure 2 and Figure 5 As shown, in one embodiment, the temperature control assembly 300 further includes a temperature sensor 330, which is disposed on the inner peripheral wall of the temperature control chamber 310 and electrically connected to the control panel 320. In one embodiment, the micro reactor 10 further includes a liquid level sensor 500, which is disposed on the inner peripheral wall of the temperature control chamber 310 and electrically connected to the control panel 320.

[0043] It is understood that by setting up the temperature sensor 330 and the liquid level sensor 500, the amount and temperature of the heat-conducting liquid in the heat-conducting liquid channel 301 can be monitored in real time, so that the user can quickly understand the temperature of the reactants in the reaction chamber 201 through the control panel. Specifically, in this embodiment, there are two liquid level sensors 500, one is a high liquid level sensor 500 and the other is a low liquid level sensor 500. The two liquid level sensors 500 are arranged at two different levels on the inner peripheral wall of the temperature control box 310.

[0044] It should be noted that, in this embodiment, the heat-conducting liquid in the heat-conducting liquid channel 301 is pure water.

[0045] like Figure 2 and Figure 3 As shown, in one embodiment, the thermoelectric cooler 430 has a plate-like structure. In another embodiment, the cold end of the thermoelectric cooler 430 is coated with a layer of silicone grease. This further improves the heat transfer rate of the thermoelectric cooler 430, allowing the control panel 320 to control the thermoelectric cooler 430 to quickly respond to cooling when the reactants in the reaction chamber 201 need to be cooled. This efficiently transfers the heat from the heat-conducting liquid to the heat dissipation fins 420, achieving better temperature control of the reactants in the reaction chamber 201.

[0046] like Figure 4 and Figure 5 As shown, in one embodiment, the temperature control box 310 has an inlet 3101 and an outlet 3102 on its side. Both the inlet 3101 and the outlet 3102 are connected to the heat-conducting liquid reservoir 301. An inlet valve 3110 is installed at the inlet 3101, and an outlet valve 3120 is installed at the outlet 3102. The inlet valve 3110 and the outlet valve 3120 are respectively connected to the water supply system through pipes. This facilitates the injection of heat-conducting liquid into the heat-conducting liquid reservoir 301 through the water supply system. Furthermore, after sufficient heat-conducting liquid has been introduced, the connecting pipes can be disassembled by closing the inlet valve 3110 and the outlet valve 3120, thereby improving the ease of transfer of the micro reactor 10 without being limited by site or auxiliary equipment.

[0047] like Figure 2 and Figure 4 As shown, in one embodiment, the stirring mechanism 100 includes multiple baffles 110, which are spaced apart around the inner peripheral wall of the reaction chamber 201. This effectively disrupts the vortices formed during stirring, resulting in better mixing of the reactants. Specifically, in this embodiment, the vessel body 200 also has multiple slots, which are spaced apart around the inner peripheral wall of the reaction chamber 201. Each baffle 110 can be easily attached and detached by snapping it into the corresponding slot. Furthermore, different media, types, and sizes of baffles 110 can be replaced to meet the needs of different experiments.

[0048] like Figure 1 and Figure 4As shown, in one embodiment, the temperature control box 310 is provided with a heat preservation cover 340 on the top, and the heat preservation cover 340 has a first through hole 3401; the vessel body 200 is provided with a vessel cover 210 on the top, and the vessel cover 210 has a second through hole 2101; the stirring end of the stirring mechanism 100 extends into the reaction chamber 201 through the first through hole 3401 and the second through hole 2101 respectively.

[0049] It is understandable that by setting the heat insulation cover 340, excessive evaporation of the heat-conducting liquid in the temperature control box 310 is better prevented, thus providing better temperature control for the reactants in the reaction chamber 201; and by setting the vessel lid 210, splashing of reactants during the stirring process of the stirring mechanism 100 is effectively prevented. In the actual use of the micro reactor 10, the user needs to first pass the stirring end of the stirring mechanism 100 through the first through hole 3401 and the second through hole 2101 in sequence, that is, first put the heat insulation cover 340 and the vessel lid 210 on the stirring end of the stirring mechanism 100.

[0050] like Figures 1 to 4 As shown, in one embodiment, the micro reactor 10 further includes a frame 600, which includes a support platform 610 and a support column 620; the support column 620 is fixed on the support platform 610; the temperature control box 310 is disposed on the support platform 610; the stirring mechanism 100 further includes a stirring motor 120 and a stirrer 130; the stirring motor 120 is mounted on the support column 620, one end of the stirrer 130 is connected to the power output end of the stirring motor 120, the other end of the stirrer 130 extends to the reaction chamber 201, and the stirring motor 120 is electrically connected to the control panel 320.

[0051] It is understood that in this embodiment, the height of the support column 620 is higher than the height of the temperature control box 310, so that the stirring motor 120 and the stirrer 130 can be placed horizontally above the temperature control box 310. In this way, the other end of the stirrer 130 can be extended from top to bottom into the reaction chamber 201, and the user can control the operation of the stirring motor 120 by operating the control panel 320.

[0052] It should be noted that in this embodiment, a first connecting rod 6210 is slidably disposed on the support column 620, and the stirring motor 120 is installed on the end of the first connecting rod 6210 away from the support column 620. Specifically, the user can drive the first connecting rod 6210 to slide up and down relative to the support column 620, thereby driving the stirring motor 120 on the first connecting rod 6210 to rise and fall, so that the other end of the stirrer 130 is placed in or away from the reaction chamber 201; in addition, the user can also rotate the first connecting rod 6210 to rotate it relative to the support column 620, so that the stirring motor 120 on the first connecting rod 6210 is placed in or away from the vessel body 200; thus, the ease of disassembling and assembling the vessel body 200 is effectively improved, especially facilitating the disassembly and cleaning of the vessel body 200.

[0053] Furthermore, the first connecting rod 6210 and the support column 620 have a sliding hole and a pin hole that are perpendicularly connected to each other at the sliding end, so that the first connecting rod 6210 can be sleeved on the support column 620 through the sliding hole, thereby realizing the sliding and rotational connection between the first connecting rod 6210 and the support column 620; and since multiple positioning holes are evenly distributed on the support column 620, the user can use pins to sequentially pass through the pin holes and the corresponding positioning holes to realize the fixed connection between the first connecting rod 6210 and the support column 620, thus restricting the rotation of the first connecting rod 6210.

[0054] like Figure 2 and Figure 6 As shown, in one embodiment, the stirrer 130 includes a rotating main shaft 1310 and a stirring element 1320; one end of the rotating main shaft 1310 is connected to the power output end of the stirring motor 120, the stirring element 1320 includes a mounting shaft 1321 and a plurality of stirring blades 1322 arranged circumferentially along the mounting shaft 1321, and the other end of the rotating main shaft 1310 is provided with a three-jaw chuck (not shown), which is used to clamp the mounting shaft 1321.

[0055] It is understandable that the clamping action of the three-jaw chuck allows users to easily disassemble and replace the stirring components 1320 with different media, types, and sizes according to different experimental needs; for example, stirring blades 1322 of different diameters (such as...). Figure 6 As shown in the figure, the stirring motor 120 is set to output different speeds or powers, so that the stirring component 1320 can achieve different stirring effects.

[0056] It should be noted that the three-jaw chuck is existing technology and will not be described in detail here.

[0057] like Figure 1 , Figure 2 and Figure 4As shown, in one embodiment, the heat-insulating cover 340 is further provided with a first injection hole 3402; the vessel cover 210 is further provided with a second injection hole 2102; the micro reactor 10 also includes an auxiliary material adding device 700, which includes a storage bin 710 and an injection pipe 720; the storage bin 710 is used to store auxiliary materials, the storage bin 710 is installed on the support column 620, one end of the injection pipe 720 is connected to the storage cavity of the storage bin 710, and the other end of the injection pipe 720 extends to the reaction chamber 201 through the first injection hole 3402 and the second injection hole 2102 respectively; an adjustment knob 7210 is provided on the injection pipe 720, and the adjustment knob 7210 is used to adjust the flow rate of the auxiliary materials through the injection pipe 720.

[0058] It should be noted that, in this embodiment, a second connecting rod 6220 is also slidably arranged on the support column 620, and the storage bin 710 is installed at the end of the second connecting rod 6220 away from the support column 620.

[0059] It is understood that the second link 6220 is movably connected to the support column 620. The connection method between the two is the same as the sliding and rotating connection method between the first link 6210 and the support column 620. The user can also use pins to sequentially pass through the pin holes of the second link 6220 and the corresponding positioning holes on the support column 620 to achieve a fixed connection between the second link 6220 and the support column 620, thereby restricting the rotation of the second link 6220.

[0060] Users can adjust the flow rate and amount of auxiliary materials injected into the reaction chamber 201 from the storage bin 710 by adjusting the knob 7210, or control the opening or stopping of the material injection from the storage bin 710 by adjusting the knob 7210.

[0061] It should be noted that in other embodiments, the injection tube 720 can be a telescopic tube. When it is necessary to remove the insulation cover 340 and the kettle cover 210, the injection tube 720 can retract towards the storage bin 710, which effectively avoids the problem of the injection tube 720 interfering with the disassembly of the insulation cover 340 and the kettle cover 210, and improves the convenience of disassembling and assembling the insulation cover 340 and the kettle cover 210.

[0062] like Figure 2 and Figure 3 As shown, in one embodiment, the bottom of the support platform 610 is provided with an anti-slip support pad 6110. In this way, the anti-slip support pad 6110 provided at the bottom of the support platform 610 can effectively increase the friction between the support platform 610 and the placement surface (such as the test bench surface of a laboratory), reducing the risk of the micro reactor 10 tilting and tipping over.

[0063] It should be noted that the miniature reactor 10 disclosed herein only protects the telecommunication connection between each component and the control panel 320, while the control method of the control panel 320 belongs to the prior art and is not within the protection scope of this disclosure.

[0064] The operating steps of the micro reactor 10 are as follows: First, connect the power supply to the micro reactor 10, open the water inlet valve 3110, and inject the heat-conducting liquid (i.e., pure water liquid) into the heat-conducting liquid channel 301 through the water supply system. After injecting a sufficient amount of pure water liquid, close the water inlet valve 3110. Place the heat insulation cover 340 and the reactor lid 210 on the stirring end of the stirring mechanism 100. Clamp the stirring element 1320 by rotating the three-jaw chuck at the other end of the main shaft 1310. Then, cover the opening of the reactor body 200 with the reactor lid 210, and simultaneously cover it with the heat insulation cover 340. Second, open the control panel 320 to set the parameters. The first stage of heating is initiated simultaneously with the stirring function. The heating rate for the first stage is 9℃ / h, and the target temperature for the first stage is 50℃. When the temperature sensor 330 detects that the temperature of the pure water liquid exceeds 50℃, the control panel 320 automatically activates the semiconductor cooling chip 430 to cool and dissipate heat, thereby stabilizing the temperature of the pure water liquid at the target value of 50℃. At this time, the adjustment knob 7210 is turned to open the storage hopper 710, and auxiliary materials are added to the reaction chamber 201. Then, the temperature of the pure water liquid is maintained at 50℃ for 20 minutes. Finally, the second stage of heating is initiated at a rate of 9℃ / hour, and the target temperature for the second stage is 95℃, which is maintained for 5 hours.

[0065] Compared with the prior art, the present invention has the following advantages, including but not limited to:

[0066] 1. The micro reactor 10 of this utility model combines heating and cooling effects, and can effectively integrate the electric heating element 410 and the semiconductor cooling chip 430 into a structural design, so that the micro reactor 10 has a good structural compactness and reduces the footprint of the micro reactor 10.

[0067] 2. By coating the cold end of the semiconductor cooling chip 430 with a silicone grease layer, the heat transfer rate of the semiconductor cooling chip 430 can be further improved. When it is necessary to cool down the reactants in the reaction chamber 201, the control panel 320 can control the semiconductor cooling chip 430 to quickly respond to cooling, efficiently transferring the heat of the heat-conducting liquid to the heat dissipation fins 420 for heat dissipation, and achieving a better temperature control effect for the reactants in the reaction chamber 201.

[0068] 3. After sufficient heat-conducting liquid is introduced, the connecting pipes can be disassembled by closing the inlet valve 3110 and the outlet valve 3120, thereby improving the convenience of transferring the micro reactor 10 without being limited by the site and auxiliary equipment.

[0069] 4. By setting the heat insulation cover 340, excessive evaporation of the heat-conducting liquid in the temperature control box 310 is better prevented, providing better temperature control for the reaction materials in the reaction chamber 201; by setting the kettle lid 210, the splashing of reaction materials during the stirring process of the stirring mechanism 100 is effectively prevented.

[0070] 5. The three-jaw chuck allows users to easily disassemble and replace stirring components 1320 with different media, types, and sizes to meet various experimental needs; for example, stirring blades 1322 of different diameters (such as...). Figure 6 As shown in the figure, the stirring motor 120 is set to output different speeds or powers, so that the stirring component 1320 can achieve different stirring effects.

[0071] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
