Description

Technical Field

[0001] This application relates to the field of ion source equipment technology, and in particular to an electrospray ion source installation mechanism with high sealing performance. Background Technology

[0002] Electrospray ionization (ESI) is a crucial tool in fields such as mass spectrometry. It is primarily used to ionize various compounds. In drug analysis, it enables precise analysis of drug components, purity, and metabolites, aiding in drug development and quality control. For biomolecules like proteins, peptides, and carbohydrates, it can convert them into multi-charged ions, facilitating the study of their structure, function, and metabolic processes. In metabolomics, it can detect metabolites in vivo to understand metabolic pathways, physiological states, and disease mechanisms. When dealing with complex mixtures such as those from the environment and food, it can be coupled with separation techniques to effectively identify components. Furthermore, the mass-to-charge ratio and fragment ion information generated can be used to study molecular structure and chemical bonds.

[0003] In existing ion source technologies, the ion source cavity is usually equipped with an observation window structure. However, when the ion source needs to be cleaned, the ion source cavity often needs to be removed. This process has many problems. Since the observation window of the ion source cavity is relatively fragile, it is easy to be damaged during disassembly, which affects the integrity of the ion source cavity and its subsequent use.

[0004] Chinese patent with announcement number "CN221668771U" discloses an integrated ion source cavity, which includes an ion source cavity body, a mounting end, a sealing end, a sealing cover connector, an observation window, a shielding and protective plate, an installation auxiliary mechanism, and a cleaning and protection mechanism. The observation window is located above the middle position of the ion source cavity body, and the shielding and protective plates are slidably connected to the upper interior of the ion source cavity body, which can effectively prevent external debris from hitting the observation window and ensure the integrity of the ion source cavity.

[0005] While the aforementioned device offers convenience to some extent, it also has significant drawbacks and shortcomings. The entire cavity is a one-piece shell structure, which tightly encloses the outside of the ion source device during disassembly and assembly, making the process extremely inconvenient. Furthermore, after the ion source device is removed, the inside of the shell also needs to be cleaned. However, due to its one-piece structure, the interior cannot be opened, making it impossible to thoroughly clean the interior during cleaning. In conclusion, this device has certain limitations in practical use and requires further improvement and refinement. Summary of the Invention

[0008] The adjustment mechanism includes a top seat, which is fixedly installed on the top of the support leg. The top seat has four X-shaped sliding grooves, and displacement components are movably installed on the inner side of each sliding groove. A locking component is fixedly installed on the top of each displacement component, and the top of the locking component is fixedly connected to the bottom of the first outer shell and the second outer shell, respectively.

[0009] Optionally, the first housing has openings on both the front and back sides, and a sealing gasket is fixedly connected inside the opening.

[0010] Optionally, observation windows are provided at both the upper and lower ends of the outer side of the second housing, and a tempered glass plate is fixedly connected inside the observation window.

[0011] Optionally, the displacement assembly includes a lead screw, which is rotatably connected to the inside of a slide groove. A bevel gear is fixedly installed at the outer end of the lead screw through the slide groove. A slider is threadedly connected to the outer surface of the lead screw, and the top of the slider is fixedly connected to the bottom of the clamping assembly.

[0012] Optionally, the mounting assembly includes a mounting rail, which is fixedly mounted on the top of the slider. A concave frame is fixedly connected to one side of the mounting rail. A limit spring is fixedly connected to the inner side of the concave frame. A limit block is fixedly connected to the inner end of the limit spring. A locking block is slidably connected to the inner side of the mounting rail. A limit groove is formed on one side of the locking block. The end of the limit block passes through the mounting rail and is inserted into the inner side of the limit groove. An mounting plate is fixedly mounted on the top of the locking block. The top of the mounting plate is connected to the first outer shell and the second outer shell respectively by bolts.

[0013] Optionally, the side shapes of the slider and the block are convex, the internal cross-sectional shape of the groove and the rail is also convex, and a wear-resistant pad is fixedly connected to the outer surface of the slider.

[0014] Optionally, the outer end of the limiting block is fixedly connected to a connecting shaft, and the outer end of the connecting shaft is fixedly installed with an adjusting handle through the concave seat.

[0015] Optionally, the limiting block has a guide slope on one side near the exit of the rail, and the end of the limiting block inside the rail is set in a right trapezoid.

[0016] Optionally, the drive mechanism includes an annular rail and a drive assembly. The annular rail is fixedly installed on the top of the base and located on the outside of the top seat. A slip ring is slidably connected inside the annular rail. An inner bevel gear ring is fixedly installed on the top of the slip ring. The inner bevel gear ring is meshed with a bevel gear. The drive assembly is fixedly installed on one side of the top of the base. The output end of the drive assembly is fixedly connected to a bevel gear.

[0017] Optionally, the drive assembly includes a fixed arm, which is fixedly installed on the middle of one side of the base. A drive motor is fixedly connected to the outer side of the fixed arm, and a connecting shaft is fixedly installed through the fixed arm at the output end of the drive motor. The end of the connecting shaft is fixedly connected to the outer side of the bevel gear.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. This device, through the cooperation of the drive mechanism and the adjustment mechanism, allows the drive motor on the fixed arm to be started during use, directly driving a bevel gear to rotate, which in turn drives the lead screw to rotate. Because the inner bevel gear ring meshes with the bevel gear, the inner bevel gear ring on the slip ring is driven, causing the four meshing bevel gears to rotate synchronously, driving the slider to slide. The slider moves inward, closing the first and second outer shells to form an installation housing, which can be used to install the ion source equipment. When the motor runs in reverse, the outer shell separates, facilitating cleaning, maintenance, and disassembly of the ion source equipment. Compared with an integrated housing, this device is faster, more efficient, and significantly more convenient.

[0020] 2. The sealing gaskets installed on the housing can fit the inner gap when the first and second outer shells are closed, ensuring good sealing performance. The sealing gaskets at the openings form a high-strength seal after the ion source equipment is installed. In addition, the device is equipped with an observation window and a tempered glass plate, which facilitates observation of the ion source equipment while maintaining sealing performance. At the same time, the tempered glass plate has strong stability, which improves the overall stability and lifespan of the device and ensures long-term reliable operation.

[0021] 3. The adjustment mechanism makes the device more convenient to use. When disassembling the ion source equipment, the drive motor is started to move the slider outward, so that the first and second shells are separated and the installation shell is unfolded. When inspecting, cleaning or replacing the shell, the adjustment handle is pulled out to disengage the limit block from the limit groove, and the locking block can be pulled out to remove the shell. After inspection and replacement, the locking block is inserted into the locking rail, and the limit block is moved outward by the guide slope to compress the limit spring. After the locking block is fully inserted, the limit spring returns to its original position and pushes the limit block into the limit groove for limitation. The various components of the installation shell can be quickly disassembled and assembled, which is convenient for inspection, cleaning and replacement, and improves the overall ease of use of the device.

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] This application discloses an electrospray ion source mounting mechanism with high sealing performance. For example... Figure 1-8 As shown, the device includes a base 1, on which support legs 2 are fixedly installed at equal intervals in a 3*2 pattern on the top of the base 1. An adjustment mechanism 3 is fixedly installed on the top of the support legs 2. A drive mechanism 6 is fixedly installed on the top of the base 1 outside the adjustment mechanism 3. The drive mechanism 6 is connected to the outside of the adjustment mechanism 3. A first housing 41 is fixedly installed on both sides of the top of the adjustment mechanism 3. A second housing 42 is fixedly installed on the other two sides of the top of the adjustment mechanism 3. Sealing strips 5 are fixedly connected to the inner sides of the first housing 41 and the second housing 42. The first housing 41 and the second housing 42 form a mounting shell 4. The sealing strips 5 are used to seal the mounting shell 4.

[0033] The adjustment mechanism 3 includes a top seat 31, which is fixedly mounted on the top of the support legs 2. The top seat 31 has four X-shaped sliding grooves 32. Displacement components 33 are movably mounted on the inner side of each sliding groove 32. A locking component 34 is fixedly mounted on the top of each displacement component 33. The top of the locking component 34 is fixedly connected to the bottom of the first outer shell 41 and the second outer shell 42, respectively. The support legs 2 arranged in a specific pattern on the base 1 provide stable support for the entire device. The top seat 31, as an important part of the adjustment mechanism 3, has four X-shaped sliding grooves 32. The four sliding grooves 32 provided by the device provide space for the displacement assembly 33 to move. The displacement assembly 33 and the clamping assembly 34 cooperate with each other to flexibly adjust the position of the first outer shell 41 and the second outer shell 42, so as to realize the quick opening and closing of the mounting housing 4. The sealing gaskets 5 on the inner side of the first outer shell 41 and the second outer shell 42 greatly improve the sealing performance of the mounting housing 4, ensure the stability of the internal environment during use, and effectively prevent external impurities from entering and affecting the operation of the ion source. This design makes the installation and disassembly of the ion source more convenient and efficient. At the same time, the improved sealing performance also helps to improve the accuracy and reliability of the ion source operation.

[0034] Please refer to Figures 1-4The first outer casing 41 has openings 43 on both the front and back, with sealing gaskets 46 fixedly connected inside the openings 43. The second outer casing 42 has observation windows 44 at both the top and bottom of its outer side, with tempered glass plates 45 fixedly connected inside the observation windows 44. The sealing gaskets 46 fixedly connected inside the openings 43 on the front and back of the first outer casing 41 ensure a tight fit with the ion source equipment during installation, forming a high-strength seal and effectively preventing external impurities from entering the installation casing 4, thus ensuring a pure working environment for the ion source. The tempered glass plates 45 fixedly connected inside the observation windows 44 at both the top and bottom of the outer side of the second outer casing 42 provide high strength and stability, allowing it to withstand certain external impacts without damage, thus improving the overall service life of the device. Furthermore, the observation windows 44 allow users to easily observe the operation of the ion source equipment inside the installation casing 4 without disassembling the installation casing 4, facilitating timely detection and handling of problems, and greatly improving the convenience and safety of the device.

[0035] Please refer to Figures 1-6The displacement assembly 33 includes a lead screw 331, which is rotatably connected to the inside of a slide groove 32. A bevel gear 332 is fixedly installed at the outer end of the lead screw 331, penetrating the slide groove 32. A slider 333 is threaded onto the outer surface of the lead screw 331. The top of the slider 333 is fixedly connected to the bottom of a mounting assembly 34. The mounting assembly 34 includes a retaining rail 341, which is fixedly installed on the top of the slider 333. A concave frame 342 is fixedly connected to one side of the retaining rail 341. A limit spring 343 is fixedly connected to the inner side of the concave frame 342. The inner end of the 3 is fixedly connected to a limiting block 344. A locking block 345 is slidably connected to the inner side of the locking rail 341. A limiting groove 346 is formed on one side of the locking block 345. The end of the limiting block 344 passes through the locking rail 341 and is inserted into the inner side of the limiting groove 346. A mounting plate 347 is fixedly installed on the top of the locking block 345. The top of the mounting plate 347 is connected to the first outer shell 41 and the second outer shell 42 respectively by bolts. In the displacement assembly 33, the lead screw 331 is rotatably connected inside the slide groove 32. The bevel gear 332 at the outer end can be connected to the drive mechanism 6 for transmission, realizing... Precise power transmission allows the lead screw 331 to rotate, causing the slider 333, threaded to its outer surface, to move smoothly within the groove 32. This, in turn, moves the mounting assembly 34 and the connected first and second housings 41 and 42, enabling the opening and closing of the housing 4. This precise control of the housing's position facilitates the installation and removal of the ion source equipment. In the mounting assembly 34, the mounting rail 341 is fixedly connected to the top of the slider 333, providing a stable sliding track for the mounting block 345. The limiting spring 343 and limiting block 344 inside the concave frame 342 are connected to the mounting block 345. With the limiting groove 346 on one side engaged, when the locking block 345 is inserted into the locking rail 341, the limiting block 344 is inserted into the limiting groove 346 under the action of the limiting spring 343, thus achieving a firm engagement of the locking block 345 and ensuring a stable connection between the mounting plate 347 and the first outer shell 41 and the second outer shell 42. The mounting plate 347 is connected to the outer shell by bolts, which is convenient for installation and disassembly. Different outer shell components can be quickly replaced according to actual needs. This design makes the entire device highly flexible and reliable during use, and facilitates the maintenance and adjustment of the ion source equipment.

[0036] Please refer to Figures 4-8The slider 333 and the locking block 345 have a convex shape on their sides, and the internal cross-section of the slide groove 32 and the locking rail 341 is also convex. A wear-resistant pad is fixedly connected to the outer surface of the slider 333. A connecting shaft 348 is fixedly connected to the outer end of the limiting block 344. An adjusting handle is fixedly installed through the concave seat at the outer end of the connecting shaft 348. A guide slope 349 is provided on the side of the limiting block 344 near the outlet of the locking rail 341. The end of the limiting block 344 located inside the locking rail 341 is set in a right-angled trapezoid. The slider 333 and the locking block 345 have a convex shape on their sides, and the internal cross-section of the slide groove 32 and the locking rail 341 is also convex. This shape design makes the sliding of the slider 333 in the slide groove 32 and the locking block 345 in the locking rail 341 more stable, and less prone to displacement or falling off, ensuring the stability of the displacement component 33 and the locking mechanism. The reliability of component 34 during operation is enhanced by the wear-resistant pads on the outer surface of slider 333, which reduce frictional loss between slider 333 and slide groove 32, extending the service life of the device. The connecting shaft 348 and adjusting handle at the outer end of limit block 344 allow operators to quickly adjust the position of locking block 345 when needed, facilitating easy assembly and disassembly of the first outer shell 41 and the second outer shell 42. The guide slope 349 on one side of limit block 344 and the right-angled trapezoidal end design allow the guide slope 349 to be squeezed when locking block 345 is inserted into the locking rail 341, causing limit block 344 to move automatically outward. After being guided, when locking block 345 is fully inserted, limit block 344 is inserted into limit groove 346 under the action of limit spring 343 to achieve locking. The entire process is simple and efficient, further improving the ease of use and practicality of the device.

[0037] Please refer to 1- Figure 6The drive mechanism 6 includes an annular rail 61 and a drive assembly 62. The annular rail 61 is fixedly installed on the top of the base 1 and located outside the top seat 31. A slip ring 63 is slidably connected inside the annular rail 61. An inner bevel gear ring 64 is fixedly installed on the top of the slip ring 63, and the inner bevel gear ring 64 is meshed with a bevel gear 332. The drive assembly 62 is fixedly installed on one side of the top of the base 1. The output end of the drive assembly 62 is fixedly connected to a bevel gear 332. The drive assembly 62 includes a fixed arm 621, which is fixedly installed in the middle of one side of the base 1. A drive motor 622 is fixedly connected to the outside of the fixed arm 621. A connecting shaft 623 is fixedly installed through the fixed arm 621. The end of the connecting shaft 623 is fixedly connected to the outside of the bevel gear 332. The annular rail 61 is fixed on the top of the base 1 and located outside the top seat 31, serving as a sliding... Ring 63 provides a stable sliding track. The inner bevel ring 64 at the top of the slip ring 63 meshes with the bevel gear 332 to transmit power. The fixed arm 621 in the drive assembly 62 provides a stable mounting position for the drive motor 622, ensuring stable motor operation. The output end of the drive motor 622 is fixedly connected to a bevel gear 332 through a coupling shaft 623. After the motor is started, it can directly drive the bevel gear 332 to rotate, which in turn drives the lead screw 331 to rotate, realizing the movement of the slider 333 in the slide groove 32, thereby controlling the opening and closing of the first housing 41 and the second housing 42. This design makes the entire device's drive process efficient, stable, and precise, enabling quick and convenient installation and disassembly of the ion source equipment, as well as cleaning and maintenance of the inside of the mounting housing 4. At the same time, this mechanical transmission method improves the automation level and ease of operation of the device.

[0038] The implementation principle of the electrospray ion source installation mechanism with high sealing performance in this application embodiment is as follows: By setting the drive mechanism 6 and the adjustment mechanism 3 to cooperate with each other, the drive motor 622 can be started to run during actual use. When the drive motor 622 on the fixed arm 621 runs, it can directly drive a bevel gear 332 to rotate. When the bevel gear 332 rotates, the lead screw 331 connected to it will also rotate. During the rotation of the bevel gear 332, since the inner bevel gear ring 64 and the bevel gear 332 are meshed, the inner bevel gear ring 64 on the slip ring 63 will be driven by the bevel gear 332. As the slip ring 63 slides on the inner side of the annular rail 61, it can synchronously drive the four bevel gears 332 meshed with the inner bevel gear ring 64 to rotate. At this time, the synchronous rotation of the four bevel gears 332 can drive the sliders 333 inside all the slide grooves 32. By driving each slider 333 to move inward, the first outer shell 41 and the second outer shell 42 can be moved inward simultaneously. When the first outer shell 41 and the second outer shell 42 are closed together, the mounting shell 4 is formed. During use, the ion source device can be installed inside the mounting shell 4. If the drive motor 622 is started to run in reverse and rotate, the lead screw 331 can drive the slider 333 to move outward. The outward movement of the slider 333 can drive the first outer shell 41 and the second outer shell 42 to separate from each other, and the entire mounting shell 4 can be opened. This design makes it easy to clean and maintain the inside of the mounting shell 4, and also allows for quick disassembly and assembly of the ion source device. Compared with the integrated shell in the prior art, this device can more quickly disassemble and maintain the ion source and the inside of the mounting shell 4, making it more convenient and efficient to use.

[0039] By setting a sealing gasket 5 on the mounting housing 4, it can play an important role in actual use. The sealing gasket 5 can help fit the inner side of the first housing 41 and the second housing 42. When the first housing 41 and the second housing 42 are closed to form a housing, the sealing gasket 5 can seal the gaps on their inner sides, so that the first housing 41 and the second housing 42 can have good sealing performance after they are closed. In addition, during use, a sealing gasket 46 is set inside the opening 43. The sealing gasket 46 can cooperate with the opening 43 to form a high-strength sealing performance after the ion source equipment is installed. In addition, this device is equipped with an observation window 44, which can be used to observe the condition of the ion source equipment. The tempered glass plate 45, while maintaining the sealing performance, facilitates observation of the inside of the mounting housing 4. At the same time, the tempered glass plate 45 has strong overall stability, which can improve the overall stability and life of the device and ensure that the device can operate reliably during long-term use.

[0040] By setting the adjustment mechanism 3, if the ion source device needs to be disassembled during use, the drive motor 622 is started to drive the lead screw 331 to drive the slider 333 to slide outward inside the slide groove 32. At this time, the slider 333 can drive the first outer shell 41 and the second outer shell 42 to move outward, thereby unfolding the mounting shell 4. When the first outer shell 41 and the second outer shell 42 need to be inspected, cleaned or replaced, the adjustment handle at the outer end of the connecting shaft 348 can be pulled to pull the connecting shaft 348, causing the limiting block 344 to move outward. After the limiting block 344 moves outward, it can be disengaged from the limiting groove 346, and the limiting block 344 and the limiting groove 346 are separated. Then the locking block 345 can be pulled out from the inside of the locking rail 341. The mounting plate 347 on the top of the locking block 345 is connected to the first outer shell 41 or the second outer shell 42 by bolts. At this time, the first outer shell 41 and the second outer shell 42 can be adapted to be disassembled. After the second outer shell 42 is removed and the maintenance and replacement are completed, simply insert the locking block 345 into the inner side of the locking rail 341. The locking block 345 presses against the guide slope 349. The guide slope 349 is compressed and guided by the guide slope 349, which causes the limiting block 344 to move outward and press against the limiting spring 343. At this time, the limiting spring 343 is in a compressed state. When the locking block 345 is fully inserted into the inside of the locking rail 341, the limiting block 344 contacts the limiting groove 346. The limiting spring 343 resets and pushes the limiting block 344 into the inner side of the limiting groove 346. The limiting block 344 and the limiting groove 346 fit together and limit each other, which can help to lock the locking block 345 into the inner side of the locking rail 341. It can be seen that this device can not only quickly adjust the opening and separation of the housing 4, but also quickly disassemble and install the various components of the housing 4. Whether it is maintenance and cleaning or disassembly and replacement, it is more convenient and can further improve the overall ease of use of this device.

[0041] 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.
