Description

Technical Field

[0001] The present application relates to the technical field of electrospray sealing connection, and in particular to an inlet connector of an electrospray structure with high sealing performance. Background Art

[0002] In modern mass spectrometry analysis technology, as a key component for realizing sample ionization, the stability and efficient operation of the liquid supply system of the electrospray structure are crucial. As the core component connecting the liquid supply pipeline and the relevant interfaces of the electrospray structure, the liquid supply pipeline connector plays an indispensable role. It not only needs to ensure a tight connection with the liquid supply pipeline from the high-pressure infusion pump and the inlet of the spray needle or spray chamber to achieve a firm fixation at the physical level and ensure the coherence of the liquid supply path, but also needs to have good sealing performance to maintain the stable working state of the entire liquid supply system.

[0003] Currently, for the liquid supply system of the electrospray structure, there are already a variety of related technologies and devices. For example, the Chinese patent with the publication number "CN221551827U" discloses a capillary electrophoresis sheath liquid electrospray device. By setting a cap body positioning hole on the sheath liquid needle assembly to cooperate with the sheath liquid positioning member on the sheath liquid main body for positioning, the positioning problem of the side liquid inlet hole of the sheath liquid needle is effectively solved, greatly facilitating the operator to install or replace the sheath liquid needle in a timely manner, and also facilitating the replacement of the capillary, improving the convenience of instrument use to a certain extent.

[0004] However, during the actual application process of this device, some problems that urgently need to be solved have still emerged. Its liquid inlet joint structure is relatively simple and mainly relies on the threaded connection method for docking. When the mass spectrometer is running, the ion source is extremely vulnerable to vibrations caused by various factors. Internal factors include the movement of mechanical components, such as the vibration generated when the mechanical pump operates and the adjustment mechanisms such as movable electrodes work, the impact of gas flow, that is, the high-speed flow of gas in the pipeline and the impact caused by internal injection and diffusion during the operation of the ion source, resulting in vibrations, the action of electromagnetic force, that is, the electromagnetic force generated by the change of the electromagnetic field. When the frequency of the alternating electric field is close to the natural frequency of the component, resonance is triggered. External factors include the transmission of the overall vibration of the instrument, such as the instrument is placed on an uneven tabletop or is interfered by nearby large equipment, causing the overall vibration of the instrument and transmitting it to the ion source, and the impact of environmental vibration. For example, the vibration generated by traffic, construction, ventilation equipment, etc. around the laboratory is transmitted to the position of the ion source through the ground and other channels, triggering vibrations. Once the ion source vibrates, this vibration will inevitably act on the threaded connection interface. In the long run, the threaded connection at the interface is very likely to slip and fall off. If it is not detected and repaired in time, it will lead to liquid leakage, which will not only seriously affect the sealing performance of the liquid supply system, thereby interfering with the detection accuracy, but also may have an adverse impact on the surrounding environment. Therefore, in order to meet the continuous development needs of mass spectrometry technology and ensure the stable and reliable operation of the liquid supply system of the electrospray structure, it is extremely urgent to improve the design of the existing liquid supply pipeline connector.

During operation, the adjusting mechanism 23 is operated, and the positioning mechanism 24 is driven to act through transmission, so that the external pipe mechanism 26 is stably installed on the connector 22. At the same time, the positioning mechanism 24 is activated to make the sealing mechanism 25 play a role, so as to seal between the connector 22 and the external pipe mechanism 26. The limiting component 5 limits the connecting device 2 after the connection is completed, ensuring a firm connection and preventing loosening during use, and ensuring the stable operation and high sealing performance of the electrospray structure inlet connector.

[0021] Please refer to Figures 1-8, the positioning mechanism 24 includes a mounting disk 241 which is fixedly installed on the outer side of the connector 22. The outer side of the mounting disk 241 is equidistantly provided with displacement adjustment components 242. The displacement adjustment components 242 are in transmission connection with the adjustment mechanism 23. On the side of the displacement adjustment component 242 away from the mounting disk 241, a clamping frame 243 is fixedly installed. The external pipe mechanism 26 is arranged between the inner sides of each clamping frame 243. The displacement adjustment component 242 includes sliding grooves 2421 which are equidistantly arranged in a ring on the outer side of the mounting disk 241. A lead screw 2422 is rotatably connected inside each sliding groove 2421. The outer end of the lead screw 2422 is fixedly connected with a bevel gear 2423. A slider 2424 is threadedly connected to the outer surface of the lead screw 2422. The clamping frame 243 is fixedly connected to the outer side of the slider 2424. The bevel gear 2423 is in meshing connection with the adjustment mechanism 23. The sealing mechanism 25 includes an elastic balloon 251, an annular arc groove 252 and an elastic annular bladder 253. The elastic balloon 251 is fixedly connected to the inner ends of the sliding grooves 2421 on the mounting disk 241. The annular arc groove 252 is opened on the inner sides of the limit block 262 and the connector 22. The elastic annular bladder 253 is arranged between the inner sides of the annular arc grooves 252 of the limit block 262 and the connector 22. The outer side of the elastic annular bladder 253 is fixedly connected with a communication pipe. The elastic annular bladder 253 is communicated with each elastic balloon 251 through the communication pipe. The positioning mechanism 24 and the sealing mechanism 25 of the present device work together to ensure the stable operation of the inlet connector of the electrospray structure. In the positioning mechanism 24, the mounting disk 241 is fixed on the outer side of the connector 22, and the displacement adjustment components 242 are equidistantly distributed on its outer side. The displacement adjustment components 242 are in transmission connection with the adjustment mechanism 23. The sliding grooves 2421 of the displacement adjustment components 242 are arranged in a ring on the outer side of the mounting disk 241, and the lead screw 2422 is rotatably connected inside. The outer end of the lead screw 2422 is connected with the bevel gear 2423, and the outer surface is in threaded cooperation with the slider 2424. The clamping frame 243 is fixed on the outer side of the slider 2424. When the adjustment mechanism 23 is operated, it drives the meshing bevel gear 2423 to rotate, thereby causing the lead screw 2422 to rotate. The lead screw 2422 drives the slider 2424 to move in the sliding groove 2421, driving the clamping frame 243 to displace, so as to firmly clamp the external pipe mechanism 26 between the inner sides of each clamping frame 243. In terms of the sealing mechanism 25, the elastic balloon 251 is fixed at the inner end of the sliding groove 2421 on the mounting disk 241. The annular arc groove 252 is located on the inner sides of the limit block 262 and the connector 22. The elastic annular bladder 253 is between the two annular arc grooves 252 and is connected to each elastic balloon 251 through the communication pipe. During the process of the clamping frame 243 clamping the external pipe mechanism 26, it pushes the slider 2424 to squeeze the elastic balloon 251. The air in the balloon enters the elastic annular bladder 253 through the communication pipe to make it expand, filling the gaps between the annular arc groove 252 and the connector 22 and the external pipe mechanism 26, realizing the sealing function.

[0022] Please refer to Figures 5-7 and Figure 9, the adjusting mechanism 23 includes an annular groove 231 which is opened on the outer side of the connector 22. A slip ring 232 is rotatably connected to the inner side of the annular groove 231. A bevel gear ring 233 is fixedly connected to the side of the slip ring 232 close to the mounting disc 241. The bevel gear ring 233 is in transmission connection with the bevel gear 2423. An adjusting handrail ring 234 is fixedly installed on the outer side of the slip ring 232. Anti-slip arc grooves 235 are equidistantly opened on the outer surface of the adjusting handrail ring 234. The limiting component 5 includes a limiting spring 52 and a limiting hole 51. The limiting spring 52 is fixedly connected to the inside of the rail frame 4. The limiting hole 51 is opened at the upper end of the adjusting handrail ring 234. An end of the limiting spring 52 is fixedly connected with a movable block 53. A limiting pin 54 is fixedly connected to the outer side of the movable block 53. The end of the limiting pin 54 penetrates through the rail frame 4 and is inserted into the limiting hole 51 in the adjusting handrail ring 234. A pushing handrail 55 is fixedly connected to the top of the movable block 53. The arrangement of the pushing handrail 55 facilitates pushing the movable block 53 to squeeze the limiting spring 52, which is convenient for quick adjustment of disassembly and assembly. The adjusting mechanism 23 and the limiting component 5 act together to realize the convenient operation and stable fixation of the inlet connector of the electrospray structure. In the adjusting mechanism 23, an annular groove 231 is opened on the outer side of the connector 22. The slip ring 232 is rotatably connected in the groove. A bevel gear ring 233 is fixedly connected to the side of the slip ring 232 close to the mounting disc 241. The adjusting handrail ring 234 is installed on the outer side, and anti-slip arc grooves 235 are arranged on its outer surface for convenient application of force. When the adjusting handrail ring 234 is rotated, the slip ring 232 rotates in the annular groove 231, driving the bevel gear ring 233 to rotate. Since the bevel gear ring 233 is in transmission connection with the bevel gear 2423 in the displacement adjusting component 242, the bevel gear ring 233 rotates to drive the bevel gear 2423, causing the lead screw 2422 to rotate, and then driving the slider 2424 to slide in the chute 2421, realizing the clamping or loosening operation of the clamping frame 243 on the external pipe mechanism 26. In terms of the limiting component 5, the limiting spring 52 is fixed in the rail frame 4. The limiting hole 51 is opened at the upper end of the adjusting handrail ring 234. The end of the limiting spring 52 is connected to the movable block 53. The limiting pin 54 is connected to the outer side of the movable block 53, and the pushing handrail 55 is fixedly connected to the top. When the connector 22 is installed on or needs to be disassembled from the external pipe mechanism 26, the pushing handrail 55 is pushed, the movable block 53 squeezes the limiting spring 52, and the limiting pin 54 disengages from the limiting hole 51 in the adjusting handrail ring 234. At this time, the adjusting handrail ring 234 can be rotated for operation; after the operation is completed, the pushing handrail 55 is released, the limiting spring 52 resets, and the movable block 53 is pushed to insert the limiting pin 54 into the limiting hole 51 to fix the adjusting handrail ring 234, ensuring the stability of the connection structure and preventing loosening due to accidental rotation during use.

[0023] Please refer to Figures 1-7, the external pipe mechanism 26 includes a socket 261 which is inserted into the inside of the connector 22. A limit block 262 is fixedly connected to the outer side of the socket 261. The limit block 262 is clamped and installed on the inner side of each clamping frame 243. The outer end of the socket 261 penetrates through the limit block 262 and is fixedly connected to a liquid inlet pipe 263. The overall shape of the limit block 262 is conical. The side shape of the clamping frame 243 is triangular. The inclined surfaces of each clamping frame 243 are inclined towards the mounting plate 241. The inner inclined surface of the clamping frame 243 is in fit connection with the outer inclined surface of the limit block 262. The external pipe mechanism 26 can achieve stable connection and fixation through cooperation with the components of the connection device 2. The external pipe mechanism 26 mainly consists of a socket 261, a limit block 262 and a liquid inlet pipe 263. During use, the socket 261 is inserted into the inside of the connector 22, and the limit block 262 on the outer side of the socket 261 is located inside each clamping frame 243. When the adjusting mechanism 23 drives the displacement component 242 to act, the lead screw 2422 rotates to make the slider 2424 slide in the chute 2421, thereby driving the clamping frame 243 to displace. Since the side of the clamping frame 243 is triangular, the inner inclined surface is inclined towards the mounting plate 241 and is in fit with the outer inclined surface of the conical limit block 262. When the clamping frame 243 displaces, its inner inclined surface and the outer inclined surface of the limit block 262 interact with each other. As the clamping frame 243 approaches the mounting plate 241, a squeezing force towards the mounting plate 241 is generated on the limit block 262, so that the limit block 262 is firmly clamped. After the limit block 262 is fixed, the socket 261 is also stably connected to the connector 22. The liquid inlet pipe 263 connected through the outer end of the socket 261 penetrating through the limit block 262 can then perform normal liquid transportation. This structural design utilizes the characteristic that the inner inclined surface of the clamping frame 243 is in fit with the outer inclined surface of the limit block 262. Driven by the adjusting mechanism 23, the reliable connection between the external pipe mechanism 26 and the connector 22 is achieved, ensuring the stability of the liquid inlet process.

[0024] Please refer to Figures 1-3 , maintenance doors 6 are installed at the top and bottom of the electrospray device body 1 through bolts. A reserved groove 7 is opened on one side of the bottom maintenance door 6 close to the rail frame 4. The main part of the rail frame 4 is accommodated inside the reserved groove 7. The design of the maintenance door 6 enables the inspection, repair or replacement of the internal components of the device. When needed, the corresponding bolts can be removed to open the maintenance door 6 to directly access the inside of the device. The reserved groove 7 opened on one side of the bottom maintenance door 6 close to the rail frame 4 is used to accommodate the main part of the rail frame 4. When installing the rail frame 4, it is placed into the reserved groove 7 and installed through bolts, and then the bottom maintenance door 6 is installed. The rail frame 4 is firmly placed inside the device. This design saves the internal space of the device, makes the structural layout more compact and reasonable; enhances the stability of the rail frame 4 inside the device, ensures that it will not displace during the operation of the device, and guarantees the normal operation of the entire electrospray device.

[0025] The implementation principle of the inlet connector of a highly sealed electrospray structure in an embodiment of the present application is as follows: The device innovatively sets up a connecting device 2, significantly optimizing the connection operation process of the liquid inlet pipe 263. When connecting the liquid inlet pipe 263, first insert the plug connector 261 into the inside of the connection head 22. At this time, the plug connector 261 is located outside the mounting plate 241. By rotating the adjusting handrail ring 234 and using its linkage structure with the sliding ring 232, drive the sliding ring 232 to perform a circular motion in the annular groove 231. The rotation of the sliding ring 232 further transmits power to the bevel gear ring 233, causing the bevel gear ring 233 to rotate synchronously. The bevel gear ring 233 meshes with a plurality of bevel gears 2423 distributed at the outer end of the chute 2421. When the bevel gear ring 233 rotates, it can synchronously drive each bevel gear 2423 to rotate around its own axis; The rotation of the bevel gear 2423 drives the lead screw 2422 connected to it to rotate in the chute 2421. The lead screw 2422 and the slider 2424 are in threaded cooperation. The rotation of the lead screw 2422 is converted into the linear sliding of the slider 2424 in the chute 2421. Since a plurality of lead screws 2422 are simultaneously driven by the bevel gear ring 233, each slider 2424 can slide synchronously in the chute 2421, thereby driving each clamping frame 243 connected to the slider 2424 to perform reciprocating displacement. The inner side of the clamping frame 243 is designed to be inclined and cooperates with the conical limiting block 262. When the clamping frame 243 is displaced driven by the slider 2424, its inner inclined surface is in close contact with the outer surface of the limiting block 262 and generates a squeezing effect. With the continuous squeezing of the clamping frame 243, the limiting block 262 moves steadily towards the mounting plate 241 under the action of the squeezing force, so that the plug connector 261 is inserted more firmly into the inside of the connection head 22. Finally, by tightening the adjusting handrail ring 234, the tight docking of the connection head 22 and the plug connector 261 can be achieved. This connection method abandons the cumbersome operation of individually twisting bolts in the traditional way, greatly improving the connection efficiency. At the same time, the coordinated squeezing linkage of a plurality of lead screws 2422 can effectively press the limiting block 262, ensuring the stable fit of the limiting block 262 and the mounting plate 241, thereby maintaining good sealing performance and meeting the strict requirements of the liquid supply system for sealing performance; The limiting component 5 equipped with this device provides a strong guarantee for the connection stability and quick disassembly of the connection head 22 and the plug connector 261. After the connection head 22 and the plug connector 261 are docked, the limiting hole 51 on the adjusting handrail ring 234 will move to a position corresponding to the limiting pin 54. At this time, the limiting spring 52 in the compressed state resets, and the generated elastic force pushes the movable block 53, causing the movable block 53 to drive the limiting pin 54 to quickly insert into the inside of the limiting hole 51. The tight clamping of the limiting pin 54 and the limiting hole 51 realizes the effective fixation of the adjusting handrail ring 234, thereby ensuring the stable connection of the connection head 22 and the plug connector 261; When it is necessary to separate the connector 22 and the socket 261, first adjust the push armrest 55 to drive the movable block 53 to squeeze the limit spring 52 to contract. At this time, the limit pin 54 disengages from the inner side of the limit hole 51. Then, reverse-rotate the adjustment armrest ring 234. The rotation of the adjustment armrest ring 234 drives the bevel gear ring 233 to rotate in place. The rotation of the bevel gear ring 233 drives each bevel gear 2423 to rotate in turn, so that the lead screw 2422 rotates in the reverse direction. The reverse rotation of the lead screw 2422 causes the slider 2424 to slide outward along the chute 2421. The outward movement of the slider 2424 drives the clamping frame 243 to move outward synchronously. When the clamping frame 243 moves outward to a position where it disengages from the contact with the limit block 262, the socket 261 loses the extrusion constraint of the clamping frame 243. At this time, the socket 261 can be easily pulled out from the inside of the connector 22; The limit assembly 5 not only realizes the quick disassembly and assembly of the connector 22 and the socket 261, but also plays a powerful limiting role during use. Since the limit spring 52 always maintains an elastic force on the movable block 53, even if the device is affected by various vibrations during operation, the limit spring 52 can always provide sufficient elastic force to prompt the limit pin 54 to quickly eject and insert into the limit hole 51. Through the mutual insertion and clamping limit of the limit pin 54 and the limit hole 51, the effective clamping of the adjustment armrest ring 234 is realized, and then each lead screw 2422 is locked, ensuring that the entire connection structure always remains stable under complex working conditions and effectively avoiding the problem of connection loosening caused by vibration; By setting the sealing mechanism 25, the sealing performance of the connection part can be further improved. When installing the connector 22 and the socket 261, the operator adjusts and twists the adjustment armrest ring 234 to drive the slider 2424 to move inward. During the inward movement of the slider 2424, it is in close contact with the elastic balloon 251 and exerts an extrusion effect on it. The elastic balloon 251 and the elastic annular balloon 253 are interconnected through a communication pipeline. When the slider 2424 squeezes the elastic balloon 251, the air inside the elastic balloon 251 enters the elastic annular balloon 253 inside the annular arc groove 252 under the action of pressure through the communication pipeline; As the installation process progresses, the slider 2424 gradually squeezes the elastic balloon 251 to the maximum extent, so that almost all the air inside the elastic balloon 251 enters the elastic annular balloon 253. The elastic annular balloon 253 expands after being filled with gas, and its expanded volume can stably fill the annular arc groove 252 and the gap between the connector 22 and the socket 261. In this way, the leakage of liquid at the connection part is effectively prevented, the connection part has strong sealing performance, and the sealing reliability during the overall connection of the device is maximally improved, providing a solid sealing guarantee for the stable operation of the liquid supply system of the electrospray structure.

[0026] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
