Description

Technical Field

[0001] This invention relates to the field of detection device technology, specifically a fragrance purity detection device with a filtration function. Background Technology

[0002] Gas chromatography-mass spectrometry (GC-MS) is an analytical instrument that combines the high resolution of gas chromatography with the high sensitivity of mass spectrometry. By organically combining GC and mass spectrometry detection, it can identify various components in complex samples. It is not only highly sensitive but also has strong separation and detection capabilities for complex compounds. It is widely used in pharmaceutical intermediates, fine chemicals, natural products, environmental monitoring, food, pesticides, cosmetics, chemical reagents, and pharmaceutical testing technology development. It features efficient and rapid analysis, accurate quantitative and qualitative analysis, and simple software operation.

[0003] Gas chromatography-mass spectrometry (GC-MS) works by introducing liquid samples into the system through an inlet, where they are rapidly vaporized at high temperatures. The vaporized sample is then moved to a chromatographic column, where different components gradually separate due to differences in their partition coefficients between the stationary and mobile phases, flowing out sequentially. The results are obtained through analysis. However, because the liquid sample is exposed to the outside environment before entering the device, it may carry other substances or gases with it when placed inside. These impurities can affect the detection results during subsequent gas detection, leading to decreased accuracy. Furthermore, most GC-MS inlets are single containers, limiting the number of samples that can be detected and resulting in low detection efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a fragrance purity detection device with a filtration function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fragrance purity detection device with filtration function includes a gas chromatography module, a mass spectrometry module, and an injection module. The gas chromatography module is placed on a horizontal plane, and the injection module is located at the top of the gas chromatography module. The output end of the injection module is connected to the gas chromatography module. The mass spectrometry module is located on one side of the gas chromatography module. The top of the injection module is equipped with a centrifugation component for separating liquid particles. The bottom of the centrifugation component is equipped with a splitting component, and the bottom of the splitting component is equipped with a driving component.

[0007] Specifically, the detection device introduces a liquid sample into the system through the injection port, where it is rapidly vaporized at high temperature. The vaporized sample is then moved to the chromatographic column, where different components gradually separate due to differences in their partition coefficients between the stationary and mobile phases, flowing out sequentially. The detection results are then obtained through analysis. However, since the liquid sample is exposed to the outside environment before entering the device, it may carry other substances or gases when placed inside. These impurities can affect the detection results during subsequent gas detection, leading to a decrease in detection accuracy. The centrifugation component is used to filter out fine particulate matter from the liquid, and the splitting component prevents gas infiltration by absorbing the liquid, thus ensuring the detection results. It should also be noted that the gas chromatography module and mass spectrometry module are both necessary structures for gas chromatography-mass spectrometry (GC-MS) instruments and are both existing structures.

[0008] The injection module includes an outer shell located at the top of the gas chromatography module. The outer shell has a hollow cavity inside, and a needle insertion hole is opened at the top of the outer shell, which is connected to the hollow cavity. A discharge port is opened on one side of the outer shell, and a valve is provided at the discharge port, which is hinged to the outer shell.

[0009] Specifically, the outer shell serves as a protective component. A needle insertion hole is provided at the top of the outer shell, which is used for the input end of the needle tube to enter and discharge the liquid into the hollow cavity inside the outer shell. The pouring port is located on one side of the top of the outer shell, and it is used by the staff to pour bottled liquid into it. The valve is used to provide a sealed environment. When liquid is poured into the pouring port, the valve will be pressurized and rotate inward, thereby creating a gap that allows the liquid to enter the hollow cavity.

[0010] The centrifugal assembly includes a rotating drum, a float, and a connecting rod. The rotating drum is located inside a hollow cavity and is rotatably connected to the inside of the outer shell. A gear ring is provided on the outer wall of the rotating drum and is fixedly connected to the rotating drum. A collection groove is provided on the inner wall of the rotating drum, and a groove cover is provided on the outside of the collection groove and is fixedly connected to the rotating drum. An annular groove is provided at the bottom of the rotating drum, and a vertical groove is provided on the inner wall of the rotating drum. One end of the connecting rod is slidably connected to the vertical groove, and a float is provided at the other end of the connecting rod. An electrode block is provided between the connecting rod and the vertical groove.

[0011] Specifically, the top horizontal plane of the rotating drum is located at the bottom of the discharge port. The rotating drum is used to store liquid and is fixedly connected to the inner wall of the outer shell. The rotation of the rotating drum will cause the liquid inside to rotate, thereby applying centrifugal force to the liquid. This centrifugal force will cause the particles in the liquid to move away from the central axis of the rotating drum. Finally, the particles will be carried into the collection tank. The tank cover is used as a cover plate for the collection tank to prevent the particles from leaving the collection tank. The annular groove is located at the bottom of the rotating drum and is on the same central axis as the rotating drum. There are two electrode blocks, located at the bottom of the connecting rod and the bottom of the inner wall of the vertical groove, respectively. The two electrode blocks are electrically connected to each other. When liquid is stored in the rotating drum, the buoyancy of the liquid will push the float to move upward. The float will drive the connecting rod to move upward, and the connecting rod will drive the electrode blocks to move upward, causing the two electrode blocks to separate from each other. This will cause the capacitance value between the two electrode blocks to change. The smaller the distance, the larger the capacitance value and the higher the liquid content, and vice versa.

[0012] The diversion assembly includes a rotating disk, a gear ring, a sample cylinder, and planetary gears. The rotating disk is located at the bottom of the rotating cylinder, and its top end mates with an annular groove. A through hole is provided on the rotating disk. The sample cylinder is located at the bottom of the rotating disk, and a connecting block is provided between the sample cylinder and the rotating disk. The top end of the connecting block is fixedly connected to the bottom end of the rotating disk, and the top end of the sample cylinder is rotatably connected to the bottom end of the connecting block. The planetary gear is located at the bottom of the sample cylinder, and its top end is fixedly connected to the bottom end of the sample cylinder. The through hole, the sample cylinder, and the planetary gears are on the same central axis. There are three planetary gears, and a fixed wheel is provided between the three planetary gears. A connecting groove is provided on the outer wall of the fixed wheel, and the three planetary gears mate with the connecting groove. The gear ring is sleeved on the planetary gears, and the three planetary gears mesh with the teeth of the gear ring. An extraction component is provided inside the sample cylinder.

[0013] Specifically, a rotating disk is located at the bottom of the rotating cylinder, and a through hole is provided on the rotating disk, which is connected to an annular groove. The bottom end of the rotating disk is fixedly connected to the top end of the sample cylinder, and the through hole is connected to the internal space of the sample cylinder. There are three sample cylinders, each with a different capacity. Each of the three sample cylinders has a small planetary wheel at its bottom, and the top end of each planetary wheel is fixedly connected to the bottom end of the sample cylinder. Thus, the rotation of the planetary wheel will also drive the sample cylinder to rotate, thereby causing the liquid to slosh when heated, so that the entire liquid can be heated evenly and the heating efficiency can be improved. Then, the fixed end of the fixed wheel is fixedly connected to the bottom end of the outer shell, and the fixed wheel will not rotate. The toothed edge of the planetary wheel meshes with the toothed edge of the gear ring, so the rotation of the gear ring will drive the planetary wheel to rotate. Because the planetary wheel is engaged with the connecting groove, the planetary wheel will only rotate on its own axis. The rotation of the planetary wheel will drive the sample cylinder to rotate. The extraction component is used to provide suction, which transfers the liquid in the rotating cylinder to the sample cylinder, thereby preventing the entry of external gas during the extraction process.

[0014] The extraction assembly includes a first rotating motor, a rotating rod, and a threaded rod. The first rotating motor is located at the bottom of the sample cylinder, and its fixed end is fixedly connected to the bottom of the sample cylinder. The output end of the first rotating motor is provided with a rotating rod that passes through the bottom of the sample cylinder. A threaded rod is sleeved on the top of the rotating rod, and the threaded rod is slidably connected to the rotating rod. The threaded rod and the sample cylinder are on the same central axis. A squeezing block is provided on the threaded rod, and the squeezing block is threadedly engaged with the threaded rod. The outer wall of the squeezing block is slidably connected to the inner wall of the sample cylinder. A cleaning assembly is provided at the bottom of the squeezing block.

[0015] Specifically, the extraction component uses a first rotating motor to extract liquid from the rotating cylinder and seal the through hole. The first rotating motor acts as a power source to control the rotation of the rotating rod. The rotation of the rotating rod drives the threaded rod to rotate, which in turn drives the extrusion block to rotate. Because the extrusion block is slidably connected to the sample cylinder, the direction of rotation of the extrusion block is restricted, so that the extrusion block can only move axially on the threaded rod. The rotating rod is used to transmit the power of the first rotating motor to the threaded rod. Because the rotating rod is slidably connected to the threaded rod, the rotating rod also provides the vertical movement distance of the threaded rod. When the threaded rod moves to the top of the rotating rod, the length of the rods of both rods exactly abuts against the through hole, thus sealing the through hole.

[0016] The cleaning assembly includes a disc and a cleaning component. The disc is located at the bottom of the extrusion block and is rotatably connected to the bottom of the extrusion block. A slot is provided in the middle of the disc. The cleaning component is located on the outer wall of the disc and is fixedly connected to the outer wall of the disc. A limiting block is provided at the bottom of the disc, and a limiting groove is provided at the bottom of the sample cylinder. The limiting groove cooperates with the limiting block.

[0017] Specifically, the cleaning component works in conjunction with the extraction component to clean the internal space of the sample cylinder, preventing the previous liquid from mixing with the current liquid and causing errors in the test results. When the cleaning component moves to the bottom of the sample cylinder, it blocks the through-hole, creating a sealed space. The groove has internal teeth that mesh with the threaded rod. When the first rotating motor operates, it controls the rotating rod to rotate, which in turn drives the threaded rod to rotate. The threaded rod's extrusion block moves, which in turn drives the disc to move. Furthermore, the threaded rod also drives the disc to rotate, which in turn drives the cleaning component to rotate. This improves cleaning efficiency. When the extrusion block moves downwards to the bottom of the sample cylinder, the limiting block at the bottom of the disc will be in the limiting groove. As the disc rotates, the limiting block will engage with the protrusion in the limiting groove, and eventually the disc will stop rotating. While the first rotating motor is still working, the disc is fixed and the threaded rod rotates. The threaded rod will move upwards, and finally the top of the threaded rod will block the through hole, achieving a sealed environment for the sample cylinder. Since the liquid in the sample cylinder is drawn from the bottom of the rotating cylinder, only the liquid to be tested is in the sample cylinder, thus ensuring the accuracy of the test results.

[0018] The drive assembly includes a second rotary motor, a transmission rod, a first gear, and a second gear. The second rotary motor is located at the bottom of the housing, and its fixed end is fixedly connected to the housing. The output end of the second rotary motor is provided with a transmission rod, and the bottom end of the transmission rod is fixedly connected to the output end of the second rotary motor. The first gear is located at the top of the transmission rod, and the second gear is located in the middle of the transmission rod. The first gear meshes with the edge of the gear ring tooth, and the second gear meshes with the edge of the gear ring tooth.

[0019] Specifically, the drive assembly is used to simultaneously control the rotation of the rotating drum and the gear ring. The second rotating motor serves as a power source to control the rotation of the rotating rod. The rotation of the rotating rod drives the first gear and the second gear to rotate. The first gear drives the rotating drum to rotate, generating centrifugal force. The second gear drives the gear ring to rotate. The gear ring drives the small planetary gear to rotate. The small planetary gear drives the sample cylinder to rotate. The second gear engages with the outer tooth edge of the gear ring.

[0020] The outer casing is equipped with a heating element, and a capillary chromatography column is located on one side of the connecting block. The output end of the capillary chromatography column extends into the sample cylinder.

[0021] Specifically, the fixed end of the heating element is fixedly connected to the outer wall of the outer shell, the output end of the heating element is aligned with the rotating cylinder and the sample cylinder, and the capillary chromatographic column is used to efficiently separate different components in complex mixtures, achieving separation based on the differences in the distribution of each component between the stationary phase and the mobile phase.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this invention, the second rotating motor operates, causing the first gear to drive the rotating drum to rotate, generating centrifugal force. This centrifugal force will drive the particles in the liquid, causing the particles to move away from the central axis of the rotating drum. Finally, the particles will be carried into the collection tank. The tank cover is used as a cover plate for the collection tank to prevent the particles from leaving the collection tank, thereby improving the purity of the liquid.

[0024] 2. In this invention, when liquid enters the rotating drum, the buoyancy of the liquid will push the float to move upward, causing the two electrode blocks to separate from each other. The liquid content is indirectly determined based on the capacitance value, and the subsequent first rotating motor is controlled according to the content to ensure that the liquid content in the sample tube reaches the total liquid content required in the detection process.

[0025] 3. The first rotating motor of the present invention controls the extrusion block to move downward, thereby causing the sample tube space to expand and generating suction to draw the liquid in the rotating tube from the through hole. The disc rotates, and the disc drives the cleaning component to rotate. The cleaning component cleans the residue after the last test, thereby ensuring that the sample tube is clean.

[0026] 4. In this invention, when the extrusion block moves downwards to the bottom of the sample cylinder, the limiting block at the bottom of the disc will be in the limiting groove. As the disc rotates, the limiting block will engage with the protrusion in the limiting groove, and eventually the disc will stop rotating. While the first rotating motor is still working, its disc is fixed, and the threaded rod rotates. The threaded rod will move upwards, and finally the top of the threaded rod will block the through hole, achieving a sealed environment for the sample cylinder. Since the liquid in the sample cylinder is drawn from the bottom of the rotating cylinder, the sample cylinder contains only the liquid to be detected, thereby ensuring the accuracy of the detection results.

[0027] 5. During the liquid extraction process in the sample cylinder, the second gear drives the gear ring to rotate, the gear ring drives the small planetary gear to rotate, and the small planetary gear drives the sample cylinder to rotate, thereby making the liquid sway during the extraction and heating process, so that the whole liquid can be heated evenly and the heating efficiency is improved.

[0037] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example: Figures 1-8 As shown, the present invention provides a fragrance purity detection device with filtration function. The detection device includes a gas chromatography module 1, a mass spectrometry module 2, and an injection module 3. The gas chromatography module 1 is placed on a horizontal plane. The injection module 3 is provided at the top of the gas chromatography module 1. The output end of the injection module 3 is connected to the gas chromatography module 1. The mass spectrometry module 2 is located on one side of the gas chromatography module 1. The top of the injection module 3 is provided with a centrifugation component 4, which is used to separate liquid particles. The bottom of the centrifugation component 4 is provided with a splitting component 5, and the bottom of the splitting component 5 is provided with a driving component 9.

[0039] Specifically, the detection device introduces a liquid sample into the system through the injection port and rapidly vaporizes it at high temperature. The vaporized sample is then moved to the chromatographic column, where different components gradually separate due to differences in their partition coefficients between the stationary and mobile phases, flowing out sequentially. Finally, the detection results are obtained through analysis. However, since the liquid sample is exposed to the outside environment before entering the device, it may carry other substances or gases when placed inside. These impurities can affect the detection results during subsequent gas detection, leading to a decrease in detection accuracy. The centrifugation component 4 is used to filter out fine particulate matter from the liquid, and the splitting component 5 prevents gas infiltration by absorbing the liquid, thereby ensuring the detection results. Both the gas chromatography module 1 and the mass spectrometry module 2 are necessary structures for a gas chromatography-mass spectrometry instrument and are existing structures.

[0040] like Figures 1-3As shown, the injection module 3 includes a housing 31, which is located at the top of the gas chromatography module 1. The housing 31 has a hollow cavity 311 inside, and a needle insertion hole 312 is opened at the top of the housing 31. The needle insertion hole 312 is connected to the hollow cavity 311. A discharge port 313 is opened on one side of the housing 31, and a valve 32 is provided at the discharge port 313. The valve 32 is hinged to the housing 31.

[0041] Specifically, the outer shell 31 serves as a protective component. The top of the outer shell 31 has a needle insertion hole 312, which is used for the input end of the needle tube to enter and discharge the liquid into the hollow cavity 311 inside the outer shell 31. The pouring port 313 is located on one side of the top of the outer shell 31, and the pouring port 313 is used by the staff to pour bottled liquid. The valve 32 is used to provide a sealed environment. When liquid is poured into the pouring port 313, the valve 32 will be pressurized and rotate inward, thereby creating a gap to allow the liquid to enter the hollow cavity 311.

[0042] like Figure 3 , Figure 4 As shown, the centrifugal assembly 4 includes a rotating drum 41, a float 42, and a connecting rod 43. The rotating drum 41 is located inside the hollow cavity 311 and is rotatably connected to the inside of the outer shell 31. A gear ring 44 is provided on the outer wall of the rotating drum 41 and is fixedly connected to the rotating drum 41. A collection groove 411 is provided on the inner wall of the rotating drum 41, and a groove cover 45 is provided on the outside of the collection groove 411 and is fixedly connected to the rotating drum 41. An annular groove 412 is provided at the bottom of the rotating drum 41, and a vertical groove 413 is provided on the inner wall of the rotating drum 41. One end of the connecting rod 43 is slidably connected to the vertical groove 413, and the other end of the connecting rod 43 is provided with a float 42. An electrode block 46 is provided between the connecting rod 43 and the vertical groove 413.

[0043] Specifically, the top horizontal plane of the rotating drum 41 is located at the bottom of the discharge port 313. The rotating drum 41 is used to store liquid. The rotating drum 41 is fixedly connected to the inner wall of the outer shell 31. The rotation of the rotating drum 41 will cause the liquid inside to rotate, thereby applying centrifugal force to the liquid. This centrifugal force will drive the particles in the liquid, causing the particles to move away from the central axis of the rotating drum 41. Finally, the particles will be carried into the collection tank 411. The tank cover 45 is used as a cover plate for the collection tank 411 to prevent the particles from leaving the collection tank 411. The annular groove 412 is located at the bottom of the rotating drum 41, and the annular groove 412... 12 is on the same central axis as the rotating drum 41. It has two electrode blocks 46, located at the bottom end of the connecting rod 43 and the bottom end of the inner wall of the vertical groove 413, respectively. The two electrode blocks 46 are electrically connected to each other. When liquid is stored in the rotating drum 41, the buoyancy of the liquid will push the float 42 to move upward. The float 42 drives the connecting rod 43 to move upward, and the connecting rod 43 drives the electrode blocks 46 to move upward, causing the two electrode blocks 46 to separate from each other. This leads to a change in the capacitance value between the two electrode blocks 46. The smaller the distance, the larger the capacitance value and the higher the liquid content. Conversely, the larger the distance, the lower the liquid content.

[0044] like Figures 5-8 As shown, the flow splitting assembly 5 includes a rotating disk 51, a gear ring 52, a sample cylinder 53, and a planetary gear 54. The rotating disk 51 is located at the bottom of the rotating cylinder 41, and the top of the rotating disk 51 mates with the annular groove 412. A through hole is provided on the rotating disk 51. The sample cylinder 53 is located at the bottom of the rotating disk 51, and a connecting block 55 is provided between the sample cylinder 53 and the rotating disk 51. The top of the connecting block 55 is fixedly connected to the bottom of the rotating disk 51, and the top of the sample cylinder 53 is rotatably connected to the bottom of the connecting block 55. The planetary gear 54... 4 is located at the bottom of the sample tube 53. The top of the planetary gear 54 is fixedly connected to the bottom of the sample tube 53. The through hole, the sample tube 53 and the planetary gear 54 are on the same central axis. There are three planetary gears 54. A fixed wheel 56 is provided between the three planetary gears 54. A connecting groove is opened on the outer wall of the fixed wheel 56. The three planetary gears 54 are engaged with the connecting groove. The gear ring 52 is sleeved on the planetary gears 54. The three planetary gears 54 are engaged with the teeth of the gear ring 52. An extraction component 7 is provided inside the sample tube 53.

[0045] Specifically, the rotating disk 51 is located at the bottom of the rotating cylinder 41, and a through hole is provided on the rotating disk 51, which is connected to the annular groove 412. The bottom end of the rotating disk 51 is fixedly connected to the top end of the sample cylinder 53, and the through hole is connected to the internal space of the sample cylinder 53. There are three sample cylinders 53, each with a different capacity. Each of the three sample cylinders 53 has a small planetary gear 54 at its bottom end, and the top end of each small planetary gear 54 is fixedly connected to the bottom end of the sample cylinder 53. Thus, the rotation of the small planetary gear 54 will also drive the sample cylinder 53 to rotate, thereby causing the liquid to slosh when heated, making the entire liquid... The liquid can be heated evenly, improving heating efficiency. Then, the fixed end of the fixed wheel 56 is fixedly connected to the bottom end of the outer shell 31. The fixed wheel 56 will not rotate, and the tooth edge of the planetary wheel 54 meshes with the tooth edge inside the gear ring 52. Thus, the rotation of the gear ring 52 will drive the planetary wheel 54 to rotate. Because the planetary wheel 54 is engaged with the connecting groove, the planetary wheel 54 will only rotate on its own axis. The rotation of the planetary wheel 54 will drive the sample cylinder 53 to rotate. The extraction component 7 is used to provide suction. The liquid in the rotating cylinder 41 is transferred to the sample cylinder 53 by suction, thereby preventing the entry of external gas during the aspiration process.

[0046] like Figure 6 , Figure 7As shown, the extraction component 7 includes a first rotating motor 71, a rotating rod 72, and a threaded rod 73. The first rotating motor 71 is located at the bottom end of the sample cylinder 53. The fixed end of the first rotating motor 71 is fixedly connected to the bottom end of the sample cylinder 53. The output end of the first rotating motor 71 is provided with a rotating rod 72, which passes through the bottom end of the sample cylinder 53. The top end of the rotating rod 72 is fitted with a threaded rod 73, which is slidably connected to the rotating rod 72. The threaded rod 73 and the sample cylinder 53 are on the same central axis. A squeezing block 74 is provided on the threaded rod 73, which is threadedly engaged with the threaded rod 73. The outer wall of the squeezing block 74 is slidably connected to the inner wall of the sample cylinder 53. A cleaning component 8 is provided at the bottom end of the squeezing block 74.

[0047] Specifically, the extraction component 7 extracts the liquid from the rotating cylinder 41 and seals the through hole through the operation of the first rotating motor 71. The first rotating motor 71 serves as a power source to control the rotation of the rotating rod 72. The rotation of the rotating rod 72 drives the threaded rod 73 to rotate, and the rotation of the threaded rod 73 drives the squeezing block 74 to rotate. When the squeezing block 74 is slidably connected to the sample cylinder 53, the rotation direction of the squeezing block 74 is restricted, so that the squeezing block 74 can only move axially on the threaded rod 73. The rotating rod 72 is used to transmit the power of the first rotating motor 71 to the threaded rod 73. Because the rotating rod 72 is slidably connected to the threaded rod 73, the rotating rod 72 also provides the vertical movement distance of the threaded rod 73. When the threaded rod 73 moves to the top of the rotating rod 72, the length of the rods of both is exactly against the through hole, thus sealing the through hole.

[0048] like Figure 7 As shown, the cleaning assembly 8 includes a disc 81 and a cleaning component 82. The disc 81 is located at the bottom end of the extrusion block 74 and is rotatably connected to the bottom end of the extrusion block 74. A slot is provided in the middle of the disc 81. The cleaning component 82 is located on the outer wall of the disc 81 and is fixedly connected to the outer wall of the disc 81. A limiting block 83 is provided at the bottom end of the disc 81. A limiting groove is provided at the bottom end of the sample cylinder 53, and the limiting groove cooperates with the limiting block 83.

[0049] Specifically, the cleaning component 8 works in conjunction with the extraction component 7 through the first rotating motor 71 to clean the internal space of the sample cylinder 53, preventing the previous liquid from mixing with the current liquid and causing errors in the test results. When the cleaning component 8 moves to the bottom of the sample cylinder 53, it blocks the through-hole, creating a sealed space. The groove has internal teeth that mesh with the threaded rod 73. When the first rotating motor 71 operates, it controls the rotating rod 72 to rotate, which in turn drives the threaded rod 73 to rotate. The threaded rod 73's pressing block 74 moves, which in turn drives the disc 81 to move. Furthermore, the threaded rod 73 also drives the disc 81 to rotate, which in turn drives the cleaning component 82 to rotate. The rotating disc 81 moves downwards, thus improving cleaning efficiency. When the squeezing block 74 moves downwards, it reaches the bottom of the sample cylinder 53. The limiting block 83 at the bottom of the disc 81 will be in the limiting groove. As the disc 81 rotates, the limiting block 83 will engage with the protrusion in the limiting groove. Finally, the disc 81 stops rotating. When the first rotating motor 71 is still working, its disc 81 is fixed, and the threaded rod 73 rotates. The threaded rod 73 will move upwards. Finally, the top of the threaded rod 73 will block the through hole, realizing a sealed environment for the sample cylinder 53. Since the liquid in the sample cylinder 53 is drawn from the bottom of the rotating cylinder 41, the sample cylinder 53 contains only the liquid to be tested, thus ensuring the accuracy of the test results.

[0050] like Figure 2 As shown, the drive assembly 9 includes a second rotary motor 91, a transmission rod 92, a first gear 93, and a second gear 94. The second rotary motor 91 is located at the bottom of the housing 31, and the fixed end of the second rotary motor 91 is fixedly connected to the housing 31. The output end of the second rotary motor 91 is provided with the transmission rod 92, and the bottom end of the transmission rod 92 is fixedly connected to the output end of the second rotary motor 91. The first gear 93 is located at the top of the transmission rod 92, and the second gear 94 is located in the middle of the transmission rod 92. The first gear 93 meshes with the tooth edge of the gear ring 44, and the second gear 94 meshes with the tooth edge of the gear ring 52.

[0051] Specifically, the drive assembly 9 is used to simultaneously control the rotation of the rotating drum 41 and the gear ring 52. The second rotating motor 91 serves as a power source to control the rotation of the rotating rod 72. The rotation of the rotating rod 72 drives the first gear 93 and the second gear 94 to rotate. The first gear 93 drives the rotating drum 41 to rotate, generating centrifugal force. The second gear 94 drives the gear ring 52 to rotate. The gear ring 52 drives the small planetary gear 54 to rotate. The small planetary gear 54 drives the sample cylinder 53 to rotate. The second gear 94 is engaged with the outer tooth edge of the gear ring 52.

[0052] like Figure 3 The outer casing 31 shown is equipped with a heating element 33, and a capillary chromatographic column 34 is provided on one side of the connecting block 55. The output end of the capillary chromatographic column 34 extends into the sample cylinder 53.

[0053] Specifically, the fixed end of the heating element 33 is fixedly connected to the outer wall of the outer shell 31, the output end of the heating element 33 is aligned with the rotating cylinder 41 and the sample cylinder 53, and the capillary chromatographic column 34 is used to efficiently separate different components in complex mixtures, achieving separation based on the distribution differences of each component between the stationary phase and the mobile phase.

[0054] Working principle: The sample is poured into the rotating drum 41 through the insertion hole 312 or the pouring hole. As the liquid enters the rotating drum 41, the buoyancy of the liquid pushes the float 42 upwards, causing the two electrode blocks 46 to separate. The liquid content is indirectly determined based on the capacitance value. Then, the liquid is filtered. The second rotating motor 91 operates, causing the first gear 93 to drive the rotating drum 41 to rotate, generating centrifugal force. This centrifugal force carries the particles in the liquid away from the central axis of the rotating drum 41. Finally, the particles are carried into the collection tank 411. The tank cover 45 acts as a cover for the collection tank 411, preventing particles from escaping. After the fine particles are filtered, the first rotating motor 71 controls the squeezing block 74 to move downwards, causing the space in the sample cylinder 53 to expand, generating suction to draw the liquid from the rotating drum 41 through the through hole. During this process, the disc 81 rotates, driving the cleaning component 82 to rotate, cleaning away any residue from the previous test. Finally, when the extrusion block 74 moves downward, it reaches the bottom of the sample cylinder 53. The limiting block 83 at the bottom of the disc 81 will be in the limiting groove. As the disc 81 rotates, the limiting block 83 will engage with the protrusion in the limiting groove. Finally, the disc 81 stops rotating. While the first rotating motor 71 is still working, the disc 81 is fixed, and the threaded rod 73 rotates. The threaded rod 73 will move upward, and finally, the top of the threaded rod 73 will block the through hole, achieving a sealed environment for the sample cylinder 53. Since the liquid in the sample cylinder 53 is extracted from the bottom of the rotating cylinder 41, the sample cylinder 53 contains only the liquid to be tested, thus ensuring the accuracy of the test results. During the extraction of liquid from the sample cylinder 53, the second gear 94 drives the gear ring 52 to rotate, the gear ring 52 drives the planetary gear 54 to rotate, and the planetary gear 54 drives the sample cylinder 53 to rotate. This causes the liquid to slosh during the extraction and heating process, allowing the entire liquid to be heated evenly and improving the heating efficiency.
