[0003] Existing real-time online monitoring ion mobility spectrometers are prone to shaking during operation, resulting in poor monitoring performance and reduced detection sensitivity. Consequently, when the monitoring equipment needs maintenance after prolonged use, disassembly and assembly become difficult, increasing workload and wasting time and effort. Furthermore, the haphazard placement of pipes and detectors during use makes the equipment inconvenient to store and occupies a significant amount of space. Utility Model Content

[0006] As a preferred technical solution of this utility model: the outer wall of the storage plate is provided with an arc-shaped groove, and both the arc-shaped groove and the outer wall of the arc plate are in contact with the monitoring head.
[0007] As a preferred technical solution of this utility model: one end of the second spring is fixed to the inner wall of the cylinder, and the other end of the second spring is fixed to the outer wall of the rod.
[0008] As a preferred technical solution of this utility model: one end of the first spring is fixed to the outer wall of the pressure plate, and the other end of the first spring is fixed to the inner wall of the instrument body.
[0009] As a preferred technical solution of this utility model: there are two magnets and two blocks, and the magnets are respectively attached to the inner wall of the blocks, with the N poles of the two magnets corresponding to each other.
[0010] As a preferred technical solution of this utility model: the number of support rods is four, and the four support rods are evenly distributed at the four corners of the bottom of the block. Two of the blocks are located at the two ends of the support rods, and the block near the bottom of the support rod forms a sliding sleeve with the outer wall of the support rod.
[0011] As a preferred technical solution of this utility model: one end of the third spring is fixed to the outer wall of the circular plate, and the other end of the third spring is fixed to the inner wall of the instrument body.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This real-time online monitoring ion mobility spectrometer uses an external force to pull a limiting rod, which in turn compresses a third spring via a circular plate. This causes the limiting rod to detach from the inner wall of the fixed block, allowing for disassembly. Releasing the limiting rod with external force allows the spring force of the third spring to push the circular plate, causing the limiting rod to re-insert into the inner wall of the fixed block, enabling rapid installation. When vibration occurs during monitoring, the two magnets, with their opposite surfaces being of the same polarity, repel each other, thus damping the vibration and preventing poor monitoring quality.
[0014] 2. This real-time online monitoring ion mobility spectrometer utilizes external force to push the rod through the monitoring head, compressing the second spring. The elasticity of the second spring in the pipeline causes the arc plate to abut against the monitoring head, stabilizing it at the top of the storage plate and preventing the monitoring head from falling off and being damaged. External force is used to pull the clamping plate, causing the clamping plate to drive the pressure plate to compress the first spring. The clamping plate fits against the pipeline, achieving storage and preventing the pipeline from being placed haphazardly, occupying space and improving the practicality of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 - Figure 7 An ion mobility spectrometer for real-time online monitoring includes an instrument body 1. A block 10 is fixedly installed on the inner wall of the bottom of the instrument body 1. A support rod 11 is provided at the bottom of the block 10. A magnet 12 is provided on the inner wall of the block 10. A retaining plate 3 is slidably sleeved on the inner wall of the instrument body 1. A pressure plate 6 is fixedly installed on the outer wall of the retaining plate 3. A first spring 13 is movably sleeved on the outer wall of the retaining plate 3. A storage plate 2 is fixedly installed on the outer wall of the instrument body 1. A cylinder 7 is fixedly installed on the outer wall of the storage plate 2. A magnet 12 is fixedly installed on the inner wall of the cylinder 7. There is a second spring 14. A round rod 9 is slidably sleeved on the inner wall of the cylinder 7. An arc plate 8 is fixedly installed on the outer wall of the round rod 9. A monitoring head 5 is placed on the top of the storage plate 2. A pipe 4 is fixedly installed on the outer wall of the monitoring head 5. A monitoring device 15 is installed on the inner wall of the instrument body 1. A fixing block 16 is fixedly installed on the outer wall of the monitoring device 15. A limit rod 17 is slidably connected to the inner wall of the fixing block 16. A round plate 19 is fixedly installed on the outer wall of the limit rod 17. A third spring 18 is movably sleeved on the outer wall of the limit rod 17.
[0025] In the above structure, by installing a monitoring head 5 and a pipe 4, when the monitoring head 5 comes into contact with the analyte during use, the molecules are ionized by a high voltage to form ions, which then drift along the pipe 4 and finally reach the inner wall of the instrument body 1 for real-time monitoring.
[0026] In a preferred embodiment, the outer wall of the storage plate 2 is provided with an arc-shaped groove, and both the arc-shaped groove and the outer wall of the arc plate 8 are in contact with the monitoring head 5.
[0027] In the above structure, the outer wall of both the arc groove and the arc plate 8 is in contact with the monitoring head 5, so that when the monitoring head 5 is placed on the top of the storage plate 2, the arc plate 8 abuts against the monitoring head 5, so that the monitoring head 5 is snapped and attached to the top of the storage plate 2, thereby increasing the stability of the equipment.
[0028] In a preferred embodiment, one end of the second spring 14 is fixed to the inner wall of the cylinder 7, and the other end of the second spring 14 is fixed to the outer wall of the rod 9.
[0029] In the above structure, the other end of the second spring 14 is fixed to the outer wall of the round rod 9, and the monitoring head 5 is placed on the top of the storage plate 2. External force is used to push the round rod 9 through the monitoring head 5 to compress the second spring 14. Through the elastic force of the second spring 14 in the pipe 4, the arc plate 8 abuts against the monitoring head 5 and stabilizes it on the top of the storage plate 2, preventing the monitoring head 5 from falling off and being damaged.
[0030] In a preferred embodiment, one end of the first spring 13 is fixed to the outer wall of the pressure plate 6, and the other end of the first spring 13 is fixed to the inner wall of the instrument body 1.
[0031] In the above structure, one end of the first spring 13 is fixed to the outer wall of the pressure plate 6, and the other end of the first spring 13 is fixed to the inner wall of the instrument body 1. When the external force pulls the clamping plate 3, the clamping plate 3 drives the pressure plate 6 to compress the first spring 13. The clamping plate 3 fits into the pipe 4 to achieve storage, avoiding the pipe 4 from being placed messily and occupying space.
[0032] In a preferred embodiment, there are two magnets 12 and two blocks 10, and the magnets 12 are respectively snapped into the inner wall of the blocks 10, with the N poles of the two magnets 12 corresponding to each other.
[0033] In the above structure, magnets 12 are respectively attached to the inner wall of block 10. The corresponding faces of the two magnets 12 are of the same polarity. When there is like repulsion between the magnets 12, the two magnets 12 can generate shock absorption, so as to avoid the equipment from shaking due to vibration during transportation, which would lead to poor monitoring quality.
[0034] In a preferred embodiment, there are four support rods 11, which are evenly distributed at the four bottom corners of the block 10. Two blocks 10 are located at the two ends of the support rods 11, and the block 10 near the bottom of the support rod 11 is slidably connected to the outer wall of the support rod 11.
[0035] In the above structure, by having two blocks 10 located at the two ends of the four support rods 11 respectively, the support rods 11 can limit the position of the blocks 10, preventing the blocks 10 from shifting position during the shock absorption process, thus increasing the stability of the device.
[0036] In a preferred embodiment, one end of the third spring 18 is fixed to the outer wall of the circular plate 19, and the other end of the third spring 18 is fixed to the inner wall of the instrument body 1.
[0037] In the above structure, by pulling the limiting rod 17 with external force, the limiting rod 17 drives the circular plate 19 to compress the third spring 18, so that the limiting rod 17 is disassembled from the inner wall of the fixing block 16. By releasing the limiting rod 17 with external force, the elastic force of the third spring 18 pushes the circular plate 19 to drive the limiting rod 17 to insert into the inner wall of the fixing block 16, so as to achieve quick installation, reduce the amount of manual labor, and save time and effort.
[0038] Working Principle: The monitoring device 15 rapidly detects trace gases on the inner wall of the instrument body 1. It operates at atmospheric or near-atmospheric pressure, identifying and quantifying trace gases by analyzing the characteristic migration time of sample molecular ions in the drift tube. It operates based on applying a fixed DC voltage to the printed circuit board. After prolonged testing and observation for any momentary short circuits, when personnel need to repair the monitoring device 15, pulling the limiting rod 17 compresses the third spring 18 via the circular plate 19, causing the limiting rod 17 to detach from the inner wall of the fixing block 16. Releasing the limiting rod 17 allows the spring force of the third spring 18 to push the circular plate 19, causing the limiting rod 17 to re-insert into the inner wall of the fixing block 16, achieving rapid installation. If the device vibrates during monitoring, the two magnets 12 will respond accordingly. Since the surfaces are of the same polarity, the repulsion between like poles of magnets 12 causes the two magnets 12 to generate shock absorption, thus preventing poor monitoring quality. The block 10 at the bottom of the support rod 11 forms a sliding connection with the outer wall of the support rod 11, allowing the support rod 11 to limit the block 10 and prevent the block 10 from shifting position during shock absorption. When the equipment is no longer in use, external force is used to push the round rod 9 through the monitoring head 5 to compress the second spring 14. Through the elastic force of the second spring 14 in the pipe 4, the arc plate 8 abuts against the monitoring head 5, stabilizing it at the top of the storage plate 2, preventing the monitoring head 5 from falling off and being damaged. External force is used to pull the clamping plate 3, causing the clamping plate 3 to drive the pressure plate 6 to compress the first spring 13. The clamping plate 3 fits into the pipe 4, achieving storage and preventing the pipe 4 from being placed haphazardly, occupying space and improving the practicality of the equipment.
