Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine testing technology, and in particular to a device for extracting volatile oils for testing traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to medicinal resources extracted and processed from natural plants, animals, and minerals, guided by traditional Chinese medicine theories and relying on long-term clinical experience and unique pharmaceutical processes. These resources are widely used in the prevention, treatment, and rehabilitation of diseases. TCM herbs typically contain various active chemical components, among which volatile oils play a crucial role in quality control, efficacy research, and component analysis due to their significant pharmacological effects and biological activity.

[0003] Volatile oils, also known as essential oils, are a class of aromatic, volatile organic compound mixtures, mainly composed of low-molecular-weight substances such as monoterpenes, sesquiterpenes, and their oxidized derivatives. They are widely found in the roots, stems, leaves, and flowers of medicinal plants. Volatile oils typically possess various pharmacological effects, including antibacterial, anti-inflammatory, analgesic, carminative, and immunomodulatory properties, making them a class of highly active and valuable components in traditional Chinese medicine.

[0004] Currently, the most commonly used volatile oil extraction process is steam distillation, which involves heating water to generate steam, bringing the steam into contact with the medicinal materials, and carrying away the volatile components. These components are then collected and separated after condensation. However, in traditional steam distillation apparatuses, the medicinal materials are typically in a static state during extraction, lacking a dynamic disturbance mechanism. This leads to uneven contact of steam as it passes through the layer of medicinal materials, especially when the materials are densely packed, easily creating "dead zones" that prevent some materials from fully contacting the steam, resulting in incomplete extraction of volatile oils. Therefore, this paper proposes a device for extracting volatile oils from traditional Chinese medicine for testing purposes to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for extracting volatile oils for the testing of traditional Chinese medicine. It aims to improve the problem that medicinal materials are usually in a static state during the extraction process and lack a dynamic disturbance mechanism, which leads to uneven contact of steam when passing through the medicinal material layer. Especially when the medicinal materials are densely packed, "dead corners" are easily formed, making it difficult for some medicinal materials to fully contact the water vapor, thus causing incomplete extraction of volatile oils.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an extraction device for volatile oils in traditional Chinese medicine testing, comprising a workbench, a plurality of support frames fixedly connected to one side of the top of the workbench, a reaction cylinder installed between the plurality of support frames, a collection and stratification box fixedly connected to the other side of the top of the workbench, a flow guiding component provided inside the reaction cylinder, the flow guiding component being connected to the collection and stratification box, an installation cavity opened inside the workbench, a heating plate installed on the inner bottom wall of the installation cavity, a filter screen frame slidably connected inside the installation cavity, a tapping mechanism provided at the bottom of the filter screen frame, and a moving component provided at the outer corner of the workbench;

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-6 An embodiment of this utility model provides: an extraction device for volatile oils in traditional Chinese medicine testing, comprising a workbench 1, a plurality of support frames 2 fixedly connected to one side of the top of the workbench 1, a reaction cylinder 3 installed between the plurality of support frames 2, a collection and stratification box 4 fixedly connected to the other side of the top of the workbench 1, a flow guiding component provided inside the reaction cylinder 3, the flow guiding component being connected to the collection and stratification box 4, an installation cavity 9 opened inside the workbench 1, a heating plate 10 installed on the inner bottom wall of the installation cavity 9, a filter screen frame 12 slidably connected inside the installation cavity 9, a tapping mechanism 13 provided at the bottom of the filter screen frame 12, and a moving component 14 provided at the outer corner of the workbench 1.

[0037] Specifically, the workbench 1 provides a stable support platform for the entire device, supporting the reaction cylinder 3, the collection and stratification box 4, and other components. Multiple support frames 2 firmly support the reaction cylinder 3 on one side of the top of the workbench 1, ensuring the position of the reaction cylinder 3 is fixed and preventing it from shaking or tipping over. The reaction cylinder 3, as the main reaction site for extracting volatile oils, can be filled with cold water, which, in conjunction with the water vapor generated by heating in the mounting chamber 9, provides space for the contact between the Chinese medicine and the water vapor, allowing the volatile oils in the Chinese medicine to be extracted in a specific environment, forming a mixture of water vapor and volatile oils. The collection and stratification box 4 is used to receive the mixture of water vapor and volatile oils from the reaction cylinder 3 through the drainage component, using the difference in density between the two to separate them into layers, facilitating the subsequent collection of volatile oils, and achieving effective separation and temporary storage of the extracted volatile oils. The mounting chamber 9 houses the heating plate 10, the filter screen frame 12, and other components. The device provides installation space while isolating the heating area from other components, allowing the heat generated to be concentrated on the water to produce steam, creating the necessary conditions for the extraction of volatile oils from traditional Chinese medicine. The heating plate 10 converts electrical energy into heat energy to heat the water in the installation cavity 9, causing the water to produce steam, providing the necessary heat and steam environment for the extraction of volatile oils from traditional Chinese medicine, and is one of the energy sources driving the entire extraction process. The filter frame 12 is used to place the traditional Chinese medicine for which volatile oils need to be extracted. Through the flow guiding component in conjunction with the reaction cylinder 3 and the collection and stratification box 4, the mixture of steam and volatile oil is guided to flow and condense, realizing the collection and stratification of volatile oils. Through the tapping mechanism 13 in conjunction with the filter frame 12, the contact between the traditional Chinese medicine and steam is made more sufficient, improving the extraction efficiency of volatile oils. Through the moving component 14 in conjunction with the worktable 1, the device can be easily moved and stored, reducing the space occupied.

[0038] Reference Figure 4 and Figure 5The striking mechanism 13 includes a motor 1301, which is mounted on the outer side of the workbench 1. A transmission rod 1302 is fixedly connected to the output end of the motor 1301. Multiple striking blocks 1303 are fixedly connected to the outer side of the transmission rod 1302. Rubber pads 1304 are provided at the contact ends of the striking blocks 1303 and the filter frame 12. The striking mechanism 13 also includes four fixing plates 1305, all of which are fixedly connected to the inner wall of the mounting cavity 9. Guide rods 1306 are fixedly connected to the top of each of the four fixing plates 1305. The guide rods 1306 are connected to the filter frame. The filter frame 12 is slidably connected. Springs 1307 are fitted on the outside of the four fixed plates 1305. The two ends of the springs 1307 are fixedly connected between the filter frame 12 and the fixed plates 1305. A baffle 1308 is fixedly connected to the top of the guide rod 1306. The baffle 1308 is located above the filter frame 12. The striking mechanism 13 also includes two limiting plates 1309. The two limiting plates 1309 are fixedly connected to the outer sides of the filter frame 12. Two limiting grooves 1310 are opened on the inner side wall of the mounting cavity 9. The limiting plates 1309 are slidably connected to the limiting grooves 1310.

[0039] Specifically, the motor 1301 works in conjunction with the transmission rod 1302, driving the transmission rod 1302 to rotate, thus providing power for the striking action. The transmission rod 1302 works in conjunction with the striking block 1303, driving the striking block 1303 to rotate synchronously, thus striking the filter frame 12. The striking block 1303 works in conjunction with the rubber pad 1304, providing cushioning and protection when the striking block 1303 strikes the filter frame 12, preventing damage to the filter frame 12. Finally, the fixing plate 1305 works in conjunction with the guide rod 1306, fixing the guide rod 1306 so that the guide rod 1306 serves as a guide for the filter frame 12. The movement of the filter frame 12 is guided, ensuring its smooth vertical movement. The fixed plate 1305, in conjunction with the spring 1307 (both ends connected to the fixed plate 1305 and the filter frame 12 respectively), buffers the impact of the impact block 1303 on the filter frame 12, preventing damage from excessive impact. The guide rod 1306, in conjunction with the baffle 1308, restricts the excessive upward movement of the filter frame 12, preventing it from detaching from the guide rod 1306. The limiting plate 1309, in conjunction with the limiting groove 1310, slides along the limiting groove 1310, limiting the horizontal movement of the filter frame 12 and preventing it from swaying or shifting.

[0040] Reference Figure 1 , Figure 2 and Figure 6The moving assembly 14 includes four rotating plates 1401, which are rotatably connected to the four outer corners of the worktable 1. A fixing sleeve 1402 is fixedly connected to the outer side of the rotating plate 1401. A transmission screw 1403 is threadedly connected to the fixing sleeve 1402. A universal wheel 1404 is installed at the bottom of the transmission screw 1403. The moving assembly 14 also includes four fixing rods 1405, which are fixedly connected to the four outer sides of the worktable 1. The fixing rods 1405 are connected to the rotating plates 1401 by nuts 1406.

[0041] Specifically, by cooperating with the worktable 1, the rotating plate 1401 rotates around the four outer corners of the worktable 1, thus adjusting the position and direction of the casters 1404; by cooperating with the transmission screw 1403 through the fixed sleeve 1402, rotating the transmission screw 1403 changes its position in the fixed sleeve 1402 through threaded transmission, thus adjusting the lifting and lowering of the casters 1404; by cooperating with the transmission screw 1403 through the casters 1404, the transmission screw 1403 descends, causing the casters 1404 to contact the ground, thus facilitating the movement of the device; by cooperating with the rotating plate 1401 and the nut 1406 through the fixed rod 1405, rotating the rotating plate 1401 to engage with the fixed rod 1405, and then fixing it with the nut 1406, thus stabilizing the structure when the device is moved; in reverse operation, the fixing is released, and rotating the rotating plate 1401 is rotated to store the casters 1404, thus reducing the space occupied when the device is parked.

[0042] Reference Figure 3 and Figure 4 The drainage assembly includes an inner cylinder 5, which is fixedly connected to the inner top wall of the reaction cylinder 3. The bottom of the inner cylinder 5 is connected to a drainage pipe 8, which extends through the bottom of the reaction cylinder 3 and the top of the workbench 1 to the mounting cavity 9. The outer side of the inner cylinder 5 is connected to a spiral tube 6, and the end of the spiral tube 6 away from the inner cylinder 5 passes through the inner wall of the reaction cylinder 3 and connects to the inner cavity of the collection and stratification box 4.

[0043] Specifically, by cooperating with the inner cylinder 5 and the guide pipe 8, the mixed gas of water vapor and volatile oil enters the inner cylinder 5 through the guide pipe 8. The inner cylinder 5 guides the gas to move upward, achieving initial guidance and orientation of the mixed gas. By cooperating with the inner cylinder 5 and the spiral tube 6, the mixed gas enters the spiral tube 6 from the inner cylinder 5. The path inside the spiral tube 6 becomes longer, which prolongs the gas condensation time and improves the condensation effect. By cooperating with the spiral tube 6 and the collection and stratification box 4, the liquid condensed in the spiral tube 6 flows into the collection and stratification box 4, realizing the collection and stratification of the condensed liquid, which facilitates the subsequent extraction of volatile oil.

[0044] Reference Figure 1 and Figure 3 The collection and stratification box 4 is connected to an external container via a pipe, and the top of the reaction cylinder 3 is provided with an injection port 7.

[0045] Specifically, by collecting the stratification box 4 in conjunction with the external container, the stratified volatile oil flows into the external container through the pipe, thus realizing the convenient collection of volatile oil; through the reaction cylinder 3, in conjunction with the injection port 7, cold water is injected into the reaction cylinder 3 from the injection port 7, thus providing the necessary conditions for the condensation of the mixed gas in the reaction cylinder 3.

[0046] Reference Figure 4 and Figure 5 A partition 11 is fixedly connected to the inner wall of the mounting cavity 9. The partition 11 is located between the heating plate 10 and the transmission rod 1302.

[0047] Specifically, the partition 11 works in conjunction with the heating plate 10. The small through holes on the partition 11 prevent heat transfer and also prevent the debris of the Chinese medicine from coming into contact with the heating plate 10 and causing damage.

[0048] Reference Figure 1 and Figure 2 A sealing door 15 is provided on the outer side of the workbench 1, and the sealing door 15 is located outside the mounting cavity 9.

[0049] Specifically, by cooperating with the workbench 1, opening the sealing door 15 allows for convenient placement of Chinese medicine on the filter rack 12; closing the sealing door 15 effectively prevents heat loss from the installation cavity 9, thus enabling convenient operation of the device, improving heating efficiency, and reducing energy consumption.

[0050] Working principle: First, open the sealing door 15 and inject appropriate amount of water. Then, place the Chinese medicine for which volatile oil needs to be extracted on the filter screen 12. After placement, close the sealing door 15 and inject an appropriate amount of cold water into the reaction cylinder 3 through the injection port 7. Activate the heating plate 10 to heat the water in the installation cavity 9. The water vapor generated by the water comes into contact with the Chinese medicine placed on the filter screen 12, extracting the volatile oil from the Chinese medicine and forming a mixture of water vapor and volatile oil. The mixture enters the inner cylinder 5 through the guide pipe 8, and then enters the reaction cylinder 3. The inner cylinder 5 guides the gas, causing it to move upwards and then into the spiral tube 6. The ambient temperature around the spiral tube 6 is low, causing the mixture to cool inside the spiral tube 6. The water vapor and volatile oil condense into liquid and flow into the collection and stratification box 4 for stratification. After stratification, the mixture can be connected to an external container through a pipe to collect the volatile oil.

[0051] By starting the motor 1301, the motor 1301 drives the transmission rod 1302 to rotate, and the striking block 1303 on the transmission rod 1302 rotates accordingly. When the striking block 1303 contacts the filter screen frame 12, it strikes the filter screen frame 12, causing the Chinese medicine to vibrate on the filter screen frame 12, so that the Chinese medicine has more sufficient contact with water vapor, thereby improving the extraction efficiency of volatile oil. During the striking process, the spring 1307 plays a buffering role. At the same time, the guide rod 1306 and the limiting plate 1309 limit and guide the filter screen frame 12 in the vertical and horizontal directions, respectively, to ensure that the filter screen frame 12 vibrates stably up and down.

[0052] To move the device, rotate the drive screw 1403 to lower the caster wheel 1404 to contact the ground, supporting the workbench 1. Then, rotate the rotating plate 1401 to engage with the end of the fixed rod 1405. Fix the end of the fixed rod 1405 to the rotating plate 1401 with the nut 1406. At this point, the device can be moved using the caster wheel 1404. To fix the device, rotate the drive screw 1403 in the opposite direction to raise the caster wheel 1404 off the ground, where it is supported by the workbench 1. Then, unscrew the nut 1406 and rotate the rotating plate 1401 away from the fixed rod 1405, thereby retracting the caster wheel 1404 and reducing the space occupied.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
