Description

Technical Field

[0002] The electrospray ion source is a tool that plays a key role in fields such as mass spectrometry. It is mainly used to ionize various compounds. In drug analysis, it can accurately analyze drug composition, purity and metabolites, and assist in drug development and quality control. For biological macromolecules, such as proteins, peptides and carbohydrates, it can convert them into multiply charged ions, which is convenient for studying the structure, function and metabolic process of these macromolecules. In metabolomics, it can detect metabolites in organisms to understand metabolic pathways, physiological states and disease mechanisms. When faced with complex mixtures such as the environment and food, it can be used in conjunction with separation technology to effectively identify components. In addition, the generated ion mass-to-charge ratio and fragment ion information can also be used to study molecular structure and chemical bonds. In the existing ion source technology, the ion source chamber is usually provided with an observation window structure. However, when the ion source needs to be cleaned, the ion source chamber often needs to be disassembled. This process has many problems. Since the observation window of the ion source chamber is relatively fragile, the observation window is easily damaged during the disassembly process, thereby affecting the integrity of the ion source chamber and the subsequent use effect; The Chinese patent with the announcement number "CN221668771U" discloses an integrated ion source chamber, which includes an ion source chamber body, a mounting end, a sealing end, a sealing cover connector, an observation window, a shielding protection plate, an installation auxiliary mechanism and a cleaning protection mechanism, wherein the observation window is arranged above the middle position of the ion source chamber body, and the shielding protection plates are respectively slidably connected to the upper inner part of the ion source chamber body, which can effectively prevent external debris from knocking against the observation window, thereby ensuring the integrity of the ion source chamber; Although the above device brings convenience to a certain extent, it also has obvious defects and shortcomings. The entire cavity is an integrated shell structure. During the disassembly and assembly of the ion source device, the integrated cavity is tightly wrapped around the outside of the ion source device, which makes the disassembly and assembly process extremely inconvenient.

However, since the shell is an integrated structure, the inside cannot be opened, which makes it impossible to carefully clean the inside during cleaning.

[0023] Please refer to 1- Figure 6The driving mechanism 6 includes an annular rail 61 and a driving assembly 62. The annular rail 61 is fixedly installed on the top of the base 1 and is located on the outside of 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. The inner bevel gear ring 64 is meshed with a bevel gear 332. The driving assembly 62 is fixedly installed on one side of the top of the base 1. The output end of the driving assembly 62 is fixedly connected to a bevel gear 332. The driving assembly 62 includes a fixed arm 621. The fixed arm 621 is fixedly installed on the middle of one side of the base 1. A driving motor 622 is fixedly connected to the outside of the fixed arm 621. A coupling shaft 623 is fixedly installed on the output end of the driving motor 622 through the fixed arm 621. The end of the coupling 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 is located on the outside of the top seat 31. It is a sliding The ring 63 provides a stable sliding track, and the inner bevel gear ring 64 on the top of the slip ring 63 is meshed with the bevel gear 332 to realize power transmission. The fixed arm 621 in the drive assembly 62 provides a stable installation position for the drive motor 622 to ensure stable operation of the motor. The output end of the drive motor 622 is fixedly connected to a bevel gear 332 through a connecting shaft 623. After starting the motor, the bevel gear 332 can be directly driven to rotate, thereby driving 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 shell 41 and the second shell 42. This design makes the driving process of the entire device efficient, stable and precise, and can quickly and conveniently realize the installation and disassembly of the ion source equipment, as well as the cleaning and maintenance of the inside of the installation shell 4. At the same time, through this mechanical transmission method, the degree of automation and convenience of operation of the device are improved.

[0024] The implementation principle of the electrospray ion source installation mechanism with high sealing performance in the embodiment of the present application is as follows: by setting the driving mechanism 6 and the adjusting mechanism 3 to cooperate with each other, the driving motor 622 can be started to operate during the actual use of the device. When the driving motor 622 on the fixed arm 621 is in operation, it can directly drive a bevel gear 332 to rotate. When the bevel gear 332 rotates, the lead screw 331 connected thereto will also rotate accordingly. During the rotation of the bevel gear 332, since the inner bevel gear ring 64 and the bevel gear 332 are meshed and connected, 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, the four bevel gears 332 meshed and connected with the inner bevel gear ring 64 can be synchronously driven 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 shell 41 and the second shell 42 can be driven to move inward synchronously. When the first shell 41 and the second shell 42 are closed to each other, the installation shell 4 can be formed. During use, the ion source device can be installed inside the installation shell 4. If the drive motor 622 is started to rotate in the reverse direction, the screw rod 331 can be driven to drive the slider 333 to move outward. The outward movement of the slider 333 can drive the first shell 41 and the second shell 42 to separate from each other. At this time, the entire installation shell 4 can be opened. This design can conveniently clean and repair the interior of the installation shell 4, and can also quickly disassemble and assemble the ion source device. Compared with the integrated shell in the prior art, the device as a whole can more quickly disassemble and assemble the ion source and the interior of its installation shell 4, and the overall application is more convenient and efficient. By arranging the sealing gasket strip 5 on the installation shell 4, it can play an important role in actual use. The sealing gasket strip 5 can assist in fitting the inner side of the first shell 41 and the second shell 42. When the first shell 41 and the second shell 42 are closed to form a shell, the sealing gasket strip 5 can seal the various gaps on the inner side thereof, so that the first shell 41 and the second shell 42 can have a good sealing performance after being closed. In addition, during use, a sealing gasket 46 is arranged inside the opening 43, and the sealing gasket 46 can cooperate with the opening 43, so that a high-strength sealing performance is formed after the ion source device is installed. In addition, the device is provided with an observation window 44, which can be used to observe the condition of the ion source device, and the tempered glass plate 45 is arranged, while maintaining the sealing performance, it is convenient to observe the interior of the installation shell 4. At the same time, the tempered glass plate 45 has a strong stability as a whole, which can improve the stability and life of the overall use of the device, and ensure that the device can operate reliably during long-term use. By setting the adjustment mechanism 3, when the ion source device needs to be disassembled during use of the device, it is only necessary to start the driving motor 622 to drive the screw rod 331 to drive the slider 333 to slide toward the outside inside the slide groove 32. At this time, the slider 333 can be driven to drive the first shell 41 and the second shell 42 to move toward the outside, thereby expanding the installation shell 4. When the first shell 41 and the second shell 42 need to be inspected, cleaned or replaced, the adjustment handle at the outer end of the connecting shaft 348 can be pulled out, and the adjusting handle can pull the connecting shaft 348 so that the connecting shaft 348 pulls the limit block 344 outward. When the limit block 344 moves outward, it can be separated from the limit groove 346, and the limit block 344 and the limit groove 346 are separated from each other, so that the block 345 can be pulled out from the inside of the rail 341, and the mounting plate 347 on the top of the block 345 is connected to the first shell 41 or the second shell 42 by bolts. At this time, the first shell 41 and the second shell 42 can be adaptively connected. The second shell 42 is removed. After the inspection and replacement are completed, it is only necessary to insert the block 345 into the inner side of the rail 341. The block 345 squeezes the guide slope 349. The guide slope 349 is squeezed and guided by the guide slope 349, which can prompt the limit block 344 to move outward to squeeze the limit spring 343. At this time, the limit spring 343 is in a compressed state. When the block 345 is fully inserted into the interior of the rail 341, the limit block 344 contacts the limit groove 346. The limit spring 343 is reset to push the limit block 344 to be inserted into the inner side of the limit groove 346. The limit block 344 and the limit groove 346 are interlocked and limited with each other, which can assist in clamping and installing the block 345 on the inner side of the rail 341. It can be seen that the device can not only quickly adjust the installation shell 4 to expand and separate, but also quickly disassemble and assemble the various components of the installation shell 4. Whether it is inspection and cleaning or disassembly and replacement, it is relatively convenient, which can further improve the convenience of the overall use of the device.
