Description

Technical Field

[0001] This application relates to the field of agricultural irrigation technology, and in particular to a temperature-adjustable sampling tube. Background Technology

[0002] Currently, the mass spectrometer sampling tube is an indispensable and important component of the mass spectrometer system. It is usually made of materials with good chemical stability and mechanical strength, such as stainless steel and quartz. Its shape is a slender tubular structure. One end is tightly connected to the sample source, such as a gas storage tank, liquid delivery pipeline or solid sample introduction device, and the other end is connected to the mass spectrometer's sample introduction system. A search revealed Chinese Patent Publication No. CN220963237U, which discloses a sampling tube positioning structure for a mass spectrometer. The structure includes a positioning component, primarily composed of a mounting plate, a base cylinder, and adjusting bolts. A lifting component is provided on the upper surface of the mounting plate. Through the cooperation of the positioning component, the lifting component, and the clamping component, a suction cup is adsorbed onto a flat surface. The position of the piston plate is adjusted by turning the adjusting bolts, thereby adjusting the pressure between the piston plate and the suction cup, thus improving the suction force of the suction cup and enhancing stability. Simultaneously, the lifting component facilitates height adjustment of the clamping component, making it suitable for clamping sampling tubes of different heights. The locking bolts facilitate raising and lowering the clamping plate, thereby enabling the clamping and positioning of sampling tubes of different specifications, improving the stability of the sampling tubes, and preventing shaking from affecting mass spectrometer detection. Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: The above device is an improved design based on a mass spectrometer sampling tube in the prior art announcement number CN211602527U. It addresses the issue that the sampling tube may shake when docking with the sample, which may lead to a decrease in the connection stability between the sampling tube and the mass spectrometer during long-term use, thus requiring the replacement of the sampling tube and reducing its service life. However, after the sampling tube is installed in the aforementioned device, it is usually in a fixed position. But in practical applications, mass spectrometers often need to collect samples from different positions or angles. This clearly necessitates adjusting the direction and position of the sampling tube to ensure it is precisely aligned with the sample source, thereby ensuring accurate and representative sample collection. For example, when analyzing complex multi-component samples, since the spatial distribution of different components may be uneven, flexibly adjusting the position and orientation of the sampling tube allows for more targeted collection of samples from specific areas, thus significantly improving the accuracy of the analysis. On the other hand, if the experimental environment changes during the use of the mass spectrometer, such as the instrument's placement or its relative arrangement with other equipment, the sampling tube will obviously need to be adjusted in the direction and position to ensure the smooth progress of the sampling work and the reliability of the results. However, both products with announcement numbers "CN211602527U" and "CN211602527" have significant drawbacks in their application. Neither allows for rapid replacement of the sampling tube. Furthermore, the sampling tube is connected to the heating wire, which typically requires prolonged heating and contact with the detection solution, making the tube highly susceptible to damage. The heating wire, however, is not in contact with the solution and is generally undamaged. Neither product allows for separate replacement of the sampling tube without replacing the heating wire; each replacement necessitates replacing the heating wire and other electrical components, significantly increasing overall operating costs and making operation inconvenient. Therefore, improvements are urgently needed. For example, in some experiments, the specific distribution of samples requires frequent adjustments to the angle and position of the sampling tube, but existing devices cannot meet this requirement, severely impacting experimental efficiency and accuracy. Additionally, frequent damage to the sampling tube necessitates replacing undamaged components like the heating wire, increasing costs and wasting resources and time. Summary of the Invention

[0014] In summary, this application includes the following beneficial technical effects: 1. The device employs a linear displacement mechanism and a rotation mechanism. During use, the first motor is started to rotate the lead screw, causing the displacement block to move linearly within the rail frame. Because the sampling tube mechanism is mounted on top of the displacement block via a clamping mechanism, the movement of the displacement block can flexibly adjust the lateral displacement of the sampling tube mechanism. During displacement adjustment, the second motor is started to drive the drive gear, which meshes with the transmission gear to rotate, thereby assisting the rotation of the rail frame. Adjusting the rotation of the rail frame can flexibly change the displacement orientation of the displacement block, allowing the device to flexibly adjust the direction and angle displacement of the sampling tube during application, thus improving the versatility and adaptability of the sampling tube application. 2. The clamping mechanism allows the stainless steel sampling tube to be installed inside the electromagnetic heating tube by inserting the hexagonal sleeve between the mounting rings. Electromagnetic heating uses electromagnetic induction to generate eddy currents inside the sampling tube, which quickly generates heat. Compared with traditional heating methods, it has high heating efficiency, uniform temperature, energy saving and environmental protection, and can accurately control temperature and duration. During use, the heat insulation cover covers the outside of the electromagnetic heating coil for protection and heat insulation. The coil and the sampling tube do not contact each other, making the sampling tube easy to disassemble and replace. There is also a temperature sensor to assist in detecting and regulating the temperature. Its probe fits the sampling tube for easy removal and replacement, making it flexible and convenient to use. 3. The device employs a clamping mechanism. During application, the hexagonal sleeve is inserted into the inner side of the mounting ring. The limit spring resets, causing the movable block to insert into the clamping slot, thus stabilizing the stainless steel sampling tube. Simultaneously, the bottom slide bar of the insulation cover slides into the side groove. The limit spring resets, causing the outer end limit bracket of the connecting shaft to move upwards and insert into the limit hole, assisting in clamping the insulation cover. For disassembly, holding the handle and pushing the handle shaft causes the sliding block to slide. The guide frame abuts against the inclined surface of the inclined guide block, and the connecting shaft moves downwards, pulling the movable block and limit bracket out of the clamping slot and limit hole respectively. This allows for the removal and replacement of the sampling tube without removing the electromagnetic heating coil. The device allows for independent sampling tube replacement, offering flexibility and low cost. The coil is bolted, and the insulation cover slides, facilitating disassembly and maintenance.

The linear displacement mechanism 6 enables the sampling tube mechanism 7 to move precisely laterally. The track frame 61 provides a stable track for displacement. The first motor 62 drives the lead screw 63 to rotate, causing the displacement block 64 to slide smoothly within the track frame 61, achieving precise position adjustment. This allows it to adapt to sampling needs at different positions, improving the flexibility and accuracy of sampling. The design of the clamping mechanism 5 facilitates the installation and disassembly of the sampling tube mechanism 7. The base plate 51 is fixedly connected to the displacement block 64, ensuring the stability of the structure. The mounting ring 53 and clamping assembly 52 on the side plate 54 can firmly fix the sampling tube mechanism 7, making it less prone to loosening during operation. The covering assembly 55 can protect the sampling tube mechanism 7, and the linkage assembly 56 increases the convenience and controllability of operation.

[0020] Please refer to Figures 7-10The sampling tube mechanism 7 includes an electromagnetic heating coil 71, which is screwed onto the inner side of the mounting ring 53. A stainless steel sampling tube 72 is movably mounted on the inner side of the electromagnetic heating coil 71.

The clamping assembly 52 includes a sliding groove 521 and a hexagonal sleeve 522. The sliding groove 521 is located on the outer side of the side plate 54. A limit spring 523 is fixedly connected to the inner side of the groove 521. A movable block 524 is fixedly installed on the top of the limit spring 523. A limit block 525 is fixedly connected to the top of the movable block 524. A hexagonal sleeve 522 is fixedly installed at both ends of the stainless steel sampling tube 72.

When the slot 526 at the bottom of hexagonal sleeve 522 is inserted with limit block 525, quick and stable installation can be achieved, which is convenient for operation. The threaded joints 73 at both ends of stainless steel sampling tube 72 can be easily connected to external pipes, which enhances its versatility and practicality. Temperature sensor 74 at the upper inner end of mounting ring 53 has its detection probe attached to the outer surface of stainless steel sampling tube 72, which can detect temperature in real time and accurately, which helps to accurately control the heating process and ensure the working effect and stability of sampling tube.

[0021] Please refer to Figures 1-5 and Figures 7-10The covering component 55 includes side grooves 551, which are formed on both sides of the top of the substrate 51. A slide bar 552 is slidably connected to the inner side of the side groove 551. A heat insulation cover 553 is fixedly installed on the top of the slide bar 552, covering the outer side of the electromagnetic heating coil 71. A connecting shaft 527 is fixedly installed on the outer side of the movable block 524. Limiting brackets 528 are fixedly installed on both sides of the top of the connecting shaft 527.

The linkage component 56 includes a bottom... A base plate 561 and a guide inclined block 562 are fixedly installed on both ends of one side of a base plate 51. A bottom rail 566 is fixedly installed on the bottom of each base plate 561. A sliding block 565 is slidably connected inside the bottom rail 566. An outer guide frame 567 is fixedly installed on the outer end of the sliding block 565. The guide inclined block 562 is fixedly installed on the outer end of a connecting shaft 527. The lower end of the guide inclined block 562 is a right-angled trapezoid. The outer end of the outer guide frame 567 and the trapezoidal inclined surface of the guide inclined block 562 are fitted together. A handrail shaft 563 is fixedly installed between the inner sides of the sliding blocks 565. The outer surface of the handrail shaft 563... A handrail 564 is fixedly installed in the middle.

[0022] Please refer to Figures 1-6The rotating mechanism 3 includes a top seat 31, which is fixedly installed on the top of the fixed column 4. The top seat 31 has a gourd-shaped configuration when viewed from above. A transmission gear 32 is rotatably connected to the top of the top seat 31. A second motor 35 is fixedly installed on the bottom of the top seat 31 away from the fixed column 4. A drive gear 33 is fixedly installed through the top seat 31 at the output end of the second motor 35. The drive gear 33 meshes with the driving gear. The top of the transmission gear 32 is fixedly installed on the rail frame 61. A cover shell 34 is fixedly installed on the top of the top seat 31, covering the outside of the drive gear 33 and the transmission gear 32. The top seat 31 is gourd-shaped and serves as the upper transmission gear 32. A stable rotational support is provided. The second motor 35 drives the drive gear 33 at the output end to rotate. Since the drive gear 33 is meshed with the transmission gear 32, it can accurately drive the transmission gear 32 to rotate. The rail frame 61 is fixed on the top of the transmission gear 32, realizing the rotational drive of the rail frame 61. This allows the entire linear displacement mechanism 6 to flexibly change direction. The cover shell 34 not only protects the drive gear 33 and transmission gear 32 from external interference and damage, but also prevents dust and other impurities from entering and affecting their normal operation. This ensures the stability and reliability of the rotating mechanism 3, extends its service life, and also enhances the overall safety and aesthetics of the device.

[0023] The implementation principle of the temperature-adjustable sampling tube in this embodiment is as follows: By setting a linear displacement mechanism 6 and a rotation mechanism 3, when the device is put into use, the first motor 62 is started to operate, and the first motor 62 drives the lead screw 63 to rotate. Once the lead screw 63 starts to rotate, it can drive the displacement block 64 to perform linear displacement on the inner side of the rail frame 61. Since the sampling tube mechanism 7 is installed on the top of the displacement block 64 through the clamping mechanism 5, the lateral displacement of the sampling tube mechanism 7 can be flexibly adjusted as the displacement block 64 moves laterally. At the same time, during the displacement adjustment process, it can also... The second motor 35 is started to drive the drive gear 33 to rotate. The drive gear 33 and the transmission gear 32 are meshed. As the drive gear 33 rotates, it drives the transmission gear 32 to rotate. The rotation of the transmission gear 32 assists in the rotation of the drive rail frame 61. By adjusting the rotation of the rail frame 61, the displacement direction of the displacement block 64 can be flexibly adjusted. In this way, the sampling tube can be flexibly adjusted to move in different directions and angles during actual application, which greatly improves the overall application versatility and adaptability of the sampling tube. By setting up the clamping mechanism 5, the hexagonal sleeve 522 can be inserted between the two mounting rings 53 during use. At this time, the entire stainless steel sampling tube 72 can be installed inside the mounting rings 53, and the stainless steel sampling tube 72 is positioned inside the electromagnetic heating tube. Electromagnetic heating utilizes the principle of electromagnetic induction to induce eddy currents inside the stainless steel sampling tube 72, thereby rapidly generating heat. Compared with traditional heating methods, electromagnetic heating has many significant advantages. First, its heating efficiency is extremely high, converting energy into heat energy in a very short time, quickly raising the temperature inside the stainless steel sampling tube 72. Second, this heating method has excellent uniformity, enabling a more even temperature distribution inside the sampling tube, effectively avoiding localized overheating or underheating. In addition, electromagnetic heating is energy-saving and environmentally friendly, and can accurately control heating temperature and time, significantly reducing energy waste. It can be seen that the design of electromagnetic heating coil 71 can achieve rapid and efficient heating. At the same time, during use, since the heat insulation cover 553 covers the outside of electromagnetic heating coil 71, it can play a good protective and heat insulation role. Furthermore, the electromagnetic heating coil 71 does not need to be in direct contact with the stainless steel sampling tube 72, so the stainless steel sampling tube 72 can be easily and quickly disassembled and replaced. At the same time, it is equipped with a temperature sensor 74, which can assist in detecting and regulating the temperature. Moreover, the probe of the temperature sensor 74 is in close contact with the stainless steel sampling tube 72, which can facilitate the removal and replacement of the stainless steel sampling tube 72. The overall application is more flexible and convenient. By setting the clamping mechanism 5, during specific applications, when the hexagonal sleeve 522 is inserted into the inner side of the mounting ring 53, the limit spring 523 resets and abuts against the movable block 524, causing the limit block 525 to be inserted into the inner side of the slot 526. Because the limit block 525 and the slot 526 mutually limit each other, the hexagonal sleeve 522 can be clamped into the interior of the mounting ring 53. The hexagonal sleeve 522 is thus reinforced, allowing for stable installation of the stainless steel sampling tube 72. During this process, by adjusting the bottom of the insulation cover 553... The slider 552 slides into the side groove 551 and is reset by the limiting spring 523, which simultaneously drives the limiting bracket 528 at the outer end of the connecting shaft 527 to move upward. The outer end of the limiting bracket 528 is inserted into the limiting hole 529. Since the limiting bracket 528 and the limiting hole 529 are interlocked, they can obviously help to engage the insulation cover 553. The limiting block 525 can cooperate with the slot 526 to help to engage the stainless steel sampling tube 72. If disassembly is required, it can be done by holding the handle shaft 56. The armrest sleeve 564 on the 3rd armrest is pushed, and the armrest shaft 563 can simultaneously push the sliding block 565 to slide inside the bottom rail 566. Guided by the bottom rail 566, the guide frame 567 and the inclined guide block can be brought into contact. Guided by the inclined surface of the guide block 562, the connecting shaft 527 is moved down, causing the movable block 524 to move down. During this period, the connecting shaft 527 can also move the limiting frame 528 down. The downward movement of the movable block 524 causes the limiting block 525 to disengage from the slot 526, and the downward movement of the limiting frame 528 causes the limiting frame 528 to move down. Once disengaged from the limiting hole 529, both the hexagonal sleeve 522 and the stainless steel sampling tube 72 are no longer limited, allowing the stainless steel sampling tube 72 to be removed and replaced. The electromagnetic heating coil 71, however, does not need to be removed. This demonstrates that the entire device can independently replace the stainless steel sampling tube 72, making it flexible and cost-effective. Furthermore, the electromagnetic heating coil 71 is bolted to the inside of the mounting ring 53, allowing for easy removal of the heating coil simply by unscrewing the bolts. The sliding fit of the insulation cover 553 also facilitates the overall disassembly, assembly, and maintenance.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
