[0015] Furthermore, the interior of the isolation plate is filled with coolant.

[0016] Compared with the prior art, the advantages of this utility model are as follows: 1. When this utility model is used, when it is necessary to extract Gynostemma pentaphyllum material, the microwave reaction component generates microwaves to decompose the Gynostemma pentaphyllum raw material. The reactants enter the low-temperature reaction component. The circulating cooling component controls the low-temperature reaction component to further extract the reactants at low temperature. The filtration extraction component filters and separates the solid-liquid mixture produced in the low-temperature reaction component and finally collects it. At the same time, the circulating cooling component maintains the low-temperature environment of the filtration extraction component, so as to maintain the activity of the Gynostemma pentaphyllum material after microwave reaction and make the extraction effect better.

[0017] 2. When this invention is used, if it is necessary to microwave the raw material of Gynostemma pentaphyllum, the medicinal liquid is added through the feed tube and flows into the reaction bottle along the stir bar. The microwave generator body performs microwave reaction treatment on the medicinal liquid in the reaction bottle. By adjusting the microwave frequency and power of the microwave generator body, the drug cells are broken, and the medicinal liquid flows out the required medicinal components in a suitable environment and enters the low temperature reaction component, effectively processing the raw material.

[0018] 3. When this utility model is used, if further extraction of materials is required, the reactants in the reaction flask enter the water tank through the flow tube. The circulating cooling component transmits cold air through the connecting pipe. The cold air generates bubbles through the air bubble stone and dissolves in the water, lowering the water temperature in the tank. The temperature sensor detects the water temperature until it reaches the temperature required to dissolve the extraction medium. The material forms a solid-liquid mixture in the flow tube and enters the filtration extraction component through the flow tube, thus maintaining the activity of the Gynostemma pentaphyllum medicinal material. The outflow of the reactants is controlled by the switch valve, allowing the reactants sufficient time to undergo microwave reaction in the reaction flask.

[0019] 4. When this invention is in use, if it is necessary to adjust the low temperature, the semiconductor cooling chip installed on the partition in the refrigeration box absorbs heat, and the fan blows cold air through the connecting pipe one and the air stone to form small bubbles that dissolve in the water, thereby lowering the water temperature in the water tank. The refrigeration box cools the extraction container in the filtration and extraction component through the connecting pipe two, thus achieving a low temperature extraction environment.

[0020] 5. When using this invention, if it is necessary to extract Gynostemma pentaphyllum liquid, the reactants in the flow tube enter the filter cylinder, the filtered liquid flows out and enters the test tube, and the output end of the motor drives the tube rack to rotate, causing the test tube to change position, thus realizing multiple dispensing of materials; when it is necessary to maintain the low temperature of the extraction container, the refrigeration box transmits cold air through the connecting pipe to reduce the temperature of the liquid inside the isolation plate, and the low temperature is transmitted to the test tube to maintain the low temperature state and maintain the activity of Gynostemma pentaphyllum; the conical liquid guide port facilitates the outflow of liquid and reduces residual loss; the coolant inside the isolation plate only maintains the low temperature environment around the test tube and does not affect other devices. The test tube continues to maintain the low temperature extraction environment through the coolant, avoiding thermal degradation of active ingredients. Attached Figure Description

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A low-temperature microwave reaction device for traditional Chinese medicine includes a cabinet 1. A microwave reaction component 2 for microwave decomposition of Gynostemma pentaphyllum structure is installed at the upper end of the cabinet 1. A low-temperature control component 3 for controlling low-temperature extraction is installed in the upper cavity of the cabinet 1. A filtration extraction component 4 for extracting Gynostemma pentaphyllum material is installed in the lower cavity of the cabinet 1. The low-temperature control component 3 includes a low-temperature reaction component 31 and a circulating cooling component 32. The low-temperature reaction component 31 is connected to the microwave reaction component 2 and the filtration extraction component 4. The circulating cooling component 32 is connected to both the low-temperature reaction component 31 and the filtration extraction component 4.

[0033] When this invention is used, for the extraction of Gynostemma pentaphyllum material, microwave reaction component 2 generates microwaves to decompose the Gynostemma pentaphyllum raw material. The reactants enter the low-temperature reaction component 31, and the low-temperature reaction component 31 is controlled by the circulating cooling component 32 to further extract the reactants at low temperature. The filtration and extraction component 4 filters and separates the solid-liquid mixture produced in the low-temperature reaction component 31 and finally collects it. At the same time, the circulating cooling component 32 maintains the low-temperature environment of the filtration and extraction component 4, so as to maintain the activity of the Gynostemma pentaphyllum material after microwave reaction and make the extraction effect better.

[0034] The microwave reaction assembly 2 includes a microwave generator body 21, a support frame 22, a feed cylinder 23, a stirrer 24, and a reaction flask 25.

[0035] When this invention is used, if it is necessary to microwave the raw material of Gynostemma pentaphyllum, the medicinal liquid is added through the feed tube 23 and flows into the reaction bottle 25 along the stir bar 24. The microwave generator body 21 performs microwave reaction treatment on the medicinal liquid in the reaction bottle 25. By adjusting the microwave frequency and power of the microwave generator body 21, the drug cells are broken, and the medicinal liquid flows out the required medicinal components in a suitable environment and enters the low temperature reaction component 31, effectively processing the raw material.

[0036] The low-temperature reaction assembly 31 includes a water tank 311, a temperature sensor 312, a flow pipe 313, and a connecting pipe 314. The water tank 311 is fixedly installed on the inner rear wall of the cabinet 1. The temperature sensor 312 is fixedly installed on the left end of the water tank 311. The flow pipe 313 passes through the water tank 311. The upper end of the flow pipe 313 is fixedly connected to the liquid outlet of the reaction flask 25. The lower end of the flow pipe 313 is connected to the filtration and extraction assembly 4. One end of the connecting pipe 314 is fixedly connected to the side wall of the water tank 311. The other end of the connecting pipe 314 is connected to the circulating cooling assembly 32. The air stone is fixedly installed on the left end of the connecting pipe 314.

[0037] When this invention is in use, if further material extraction is required, the reactants in the reaction flask 25 enter the water tank 311 through the flow pipe 313. The circulating cooling component 32 transmits cold air through the connecting pipe 314. The cold air generates bubbles through the air bubble stone and dissolves in the water, lowering the water temperature in the water tank 311. The temperature sensor 312 detects the water temperature until it reaches the temperature required to dissolve the extraction medium. The material forms a solid-liquid mixture in the flow pipe 313 and enters the filtration extraction component 4 through the flow pipe 313, thus maintaining the activity of the Gynostemma pentaphyllum medicinal material.

[0038] A switch valve is fixedly installed at one end of the flow tube 313 near the reaction flask 25.

[0039] When this invention is in use, the outflow of reactants is controlled by a switch valve, allowing the reactants sufficient time to undergo microwave reaction in the reaction flask 25.

Next, the partition 324 is fixedly installed inside the refrigeration box 321, and the semiconductor refrigeration chip 325 is fixedly installed in the middle of the partition 324. The semiconductor refrigeration chip 325 absorbs heat on one side and releases heat on the other side, with the heat-absorbing end of the semiconductor refrigeration chip 325 facing to the left. The output end of the fan 322 is fixedly connected to one end of a three-way pipe, and the other two ends of the three-way pipe are fixedly connected to both sides of the partition 324 inside the refrigeration box 321. The connecting pipe between the refrigeration box 321 and the fan 322 on the lower right side leads to the outside of the cabinet 1.

[0041] When this invention is in use, if it is necessary to adjust the low temperature, the semiconductor cooling chip 325 installed on the partition 324 in the cooling box 321 absorbs heat, and the fan 322 blows cold air through the connecting pipe 314 and the air stone to form small bubbles that dissolve in the water, thereby lowering the water temperature in the water tank 311. The cooling box 321 cools the extraction container in the filter extraction component 4 through the connecting pipe 323, thereby achieving a low-temperature extraction environment.

[0042] The filtration and extraction assembly 4 includes a filter cylinder 41, a support plate 42, a motor 43, an isolation plate 44, a tube rack 45, and test tubes 46. The filter cylinder 41 is fixedly installed in the inner top of the lower cavity of the cabinet 1. The upper port of the filter cylinder 41 is fixedly connected to the flow tube 313.

The side wall of the test tube 46 is snapped into the opening on the tube rack 45. The lower end of the connecting tube 323 passes through the support plate 42 and is fixedly connected to the right side end of the isolation plate 44.

[0043] When this invention is in use, if it is necessary to extract Gynostemma pentaphyllum liquid, the reactants in the flow tube 313 enter the filter tube 41, the filtered liquid flows out and enters the test tube 46, the output end of the motor 43 drives the tube rack 45 to rotate, and drives the test tube 46 to change position, realizing multiple dispensing of materials; when it is necessary to maintain the low temperature of the extraction container, the refrigeration box 321 transmits cold air through the connecting pipe 323 to reduce the temperature of the liquid inside the isolation plate 44, and the low temperature is transmitted to the test tube 46 to maintain the low temperature state and maintain the activity of Gynostemma pentaphyllum.

[0044] The bottom of the filter cylinder 41 is tapered.

[0045] When this invention is used, the conical liquid outlet makes it easier for liquid to flow out, reducing residual loss.

[0046] The partition plate 44 is filled with coolant.

[0047] When this invention is in use, the coolant inside the isolation plate 44 only maintains the low-temperature environment around the test tube 46 without affecting other devices. The test tube 46 continues to maintain a low-temperature extraction environment through the coolant, thus avoiding thermal degradation of the active ingredients.
