Description

Technical Field

[0001] This utility model belongs to the technical field of electrospray detectors, and in particular relates to a high-efficiency electrospray detector. Background Technology

[0002] Electrospray ionization (ESI) detectors are general-purpose chromatographic detectors based on the principle of aerosol charging. In an HPLC system, the eluent and nitrogen gas collide in an nebulizer to form an atomized state. After drying, the droplets become solute particles, which then collide with charged nitrogen gas, causing the particles to become positively charged. Excess charged nitrogen gas is then removed using an ion trap. The charged particles transfer their charge on a collector, and the amount of charge is measured by an electrometer. The signal intensity is proportional to the mass of the solute.

[0003] Current electrospray detectors require an atomizing nozzle to atomize liquid materials before using a detection module to detect them. However, this process involves adding the material to be tested into the nozzle beforehand. Controlling the dosage of this addition can lead to insufficient or wasted material. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-6 As shown, this utility model is a high-efficiency electrospray detector, including a detector body 1, a transparent glass plate on the front surface of the detector body 1 to facilitate the visual observation of the inside of the detector body 1 with the naked eye in conjunction with the setting of the supplementary light 26, a display 2 fixed on the top of the front of the detector body 1, and a storage box 3 fixed on the back of the detector body 1.

[0027] It also includes: a cylinder 4 fixedly installed on one side of the bottom of the storage tank 3, and a lifting plate 5 fixedly connected to the bottom of the cylinder 4. The lifting plate 5 is movably connected to the storage tank 3 through the cylinder 4. A conveying cylinder 6 is connected to the bottom of the lifting plate 5 through a pipe. Electric spraying heads 7 are distributed below the conveying cylinder 6. The electric spraying heads 7 are evenly distributed along the center point of the rotating seat 24. The electric spraying heads 7 are controlled by a program. A contact head 8 is fixedly installed in the middle of the bottom end of the conveying cylinder 6. A conveying channel 9 is opened on the inner side of the contact head 8. The material conveying channels 9 are equidistantly distributed along the center point of the contact head 8, and are connected to the grooves 10. One end of the material conveying channel 9 is connected to the groove 10, and a rubber sealing plug 11 is engaged inside the groove 10. A guide ring 12 is fixedly provided around the top of the rubber sealing plug 11, and a return spring 13 is fixedly connected to the middle of the top of the rubber sealing plug 11. The two ends of the return spring 13 are respectively fixedly connected to the inner wall of the contact head 8 and the top of one end of the rubber sealing plug 11. The top of the electric spray head 7 is in the middle of the... A pressing head 14 is fixedly provided, and a first through hole 15 is opened on the outer surface of the pressing head 14. The first through hole 15 is equidistantly distributed along the center point of the pressing head 14. A connecting pipe 16 is fixedly connected to the bottom of the pressing head 14, and a second through hole 17 is opened on one end surface of the connecting pipe 16. The connecting pipe 16 extends to the inner side of the electric spray head 7, and the liquid inlet channel 18 is symmetrically distributed along the vertical center line of the connecting pipe 16. The liquid inlet channel 18 is opened on the inner side of the bottom of the connecting pipe 16, and a third through hole 19 is connected to one side of the top of the liquid inlet channel 18. The third through hole 19 is symmetrically distributed on both sides of the outer surface of the connecting pipe 16. A floating sealing plug 20 is provided in the inner cavity of the connecting pipe 16, and a solenoid valve 21 is distributed below the floating sealing plug 20. The length of the floating sealing plug 20 is greater than the distance between the first through hole 15 and the second through hole 17. The solenoid valve 21 can be controlled to open and close at different times, which facilitates the flow of materials in different directions according to different situations. A sensor 22 is installed on one side of the top of the electric spray head 7.

[0028] During operation, the material to be tested is added to the inside of the storage bin 3. Then, when it is necessary to add material to the inside of the electrospray head 7, the operation of the cylinder 4 is used to longitudinally push the lifting plate 5 fixedly connected to its bottom. Subsequently, the lifting plate 5 moves longitudinally to push the conveying cylinder 6 connected to its bottom through a pipe. Then, the conveying cylinder 6 moves longitudinally to push the contact head 8 fixed in the middle of its bottom end, so that the contact head 8 contacts the extrusion head 14 fixed in the middle of the top of the electrospray head 7. Then, under the extrusion action of the extrusion head 14, the rubber sealing plug 11 will move longitudinally inside the groove 10. Subsequently, the longitudinal movement of the rubber sealing plug 11 drives the guide ring 1. 2. The rubber sealing plug 11 slides along the annular groove on the inner side of the contact head 8 to improve the stability of the rubber sealing plug 11 during longitudinal movement. At the same time, the longitudinal movement of the rubber sealing plug 11 will also cause the return spring 13 to deform and generate a reverse force, which can be used to assist the rubber sealing plug 11 in longitudinal reset. When the extrusion head 14 contacts the contact head 8, it will extend into the inner side of the groove 10. At this time, the material conveying channel 9 is aligned and connected with the first through hole 15. Then, the material stored inside the material conveying cylinder 6 will be input into the inner side of the first through hole 15 through the material conveying channel 9 under pressure. The material is fed into the inner side of the connecting pipe 16 through the first through hole 15. After being fed into the inner side of the connecting pipe 16, the material is discharged through the second through hole 17, thereby feeding the material to be tested into the inner side of the electrospray head 7. After the electrospray head 7 is filled, the excess material is fed into the inner side of the liquid inlet channel 18 through the third through hole 19. Then, it enters the inner side of the connecting pipe 16 again through the liquid inlet channel 18. The material is output through the solenoid valve 21, and then, under the buoyancy of the material, it pushes the floating sealing plug 20 longitudinally, causing the floating sealing plug 20 to move to the connecting pipe 16. The top of the connector 16 is closed to seal the first through hole 15 and the second through hole 17. After the two are closed, the material feeding can be stopped. Then, the sensor 22 is used to sense whether there is a slight material overflow. When material overflow is detected, the cylinder 4 works in the opposite direction to pull the lifting plate 5, which causes the material feeding cylinder 6 to separate the contact head 8 from the extrusion head 14. At the same time, the reset spring 13 pushes the rubber sealing plug 11 in the opposite direction, and then the rubber sealing plug 11 is used to re-close the material feeding channel 9. The data obtained from the detection will be displayed on the display 2, so that the detected data can be seen more intuitively.

[0029] Furthermore, a drive motor 23 is fixedly installed in the inner cavity of the detector body 1, and a rotating seat 24 is connected to the output end of the drive motor 23.

[0030] During operation, the operation of the drive motor 23 can facilitate the rotation of the rotating base 24 connected to its output end, and the rotation of the rotating base 24 can facilitate the circular motion of the electric spray head 7.

[0031] Furthermore, a detection head 25 is fixedly installed on the inner wall of the detector body 1, and a supplementary light 26 is fixedly installed at the bottom of the inner cavity of the detector body 1.

[0032] During operation, the supplementary light 26 illuminates the interior of the detector body 1. The atomized material is then sprayed out in a sprayed shape under the influence of the supplementary light 26. The detection head 25 is then used to detect and process the atomized material. The supplementary light 26 allows the detection head 25 to better detect and process the atomized material in a dim environment.

[0033] Furthermore, an air extraction pipe 27 is fixedly provided on the side wall of the detector body 1, and an air pump 28 is connected to the other end of the air extraction pipe 27. The air extraction pipe 27 extends through the side wall of the detector body 1 and is symmetrically distributed on both sides of the detector body 1. A filter cylinder 29 is connected to the bottom of the air pump 28, and an exhaust pipe 30 is fixedly connected to the middle of the bottom end of the filter cylinder 29. The exhaust pipe 30 is connected to the bottom of the filter cylinder 29.

[0034] During operation, the air pump 28 generates suction force, and then the atomized material inside the detector body 1 is drawn into the filter cylinder 29 through the air extraction pipe 27. The filter structure set inside the filter cylinder 29 is used to filter the atomized waste material in the air, and the filtered air is discharged through the exhaust pipe 30 to prevent the surrounding air environment from being polluted.

[0035] Furthermore, the material conveying channels 9 are equidistantly distributed along the center point of the contact head 8, and the material conveying channels 9 and the contact head 8 form an integrated structure;

[0036] During operation, since the material conveying channel 9 connects the contact head 8 and the material conveying cylinder 6, the material inside the material conveying cylinder 6 will be fed into the contact head 8 through the material conveying channel 9 when feeding the inside of the electro-spray head 7, making it convenient to feed the material into the inside of the electro-spray head 7 later.

[0037] Furthermore, the suction pipe 27 extends through the side wall of the detector body 1 and into the inner side of the detector body 1, and the suction pipe 27 is symmetrically distributed along the vertical center line of the detector body 1.

[0038] During operation, the air pump 28 draws the atomized material inside the detector body 1 into the inside of the air extraction pipe 27 along with the air through the air extraction pipe 27 extending inside the detector body 1. This facilitates the subsequent input of air mixed with the atomized material into the inside of the filter cartridge 29 through the air extraction pipe 27, preventing it from affecting the normal detection and processing of the material.

[0039] Working principle: First, the material to be tested is added to the inside of the storage tank 3. Then, the cylinder 4 operates to push the lifting plate 5, which in turn pushes the conveying cylinder 6. The conveying cylinder 6 then moves longitudinally to push the contact head 8, causing the contact head 8 to contact the extrusion head 14. The extrusion head 14 then pushes the rubber sealing plug 11. At this time, the conveying channel 9 is aligned and connected with the first through hole 15. The material stored inside the conveying cylinder 6 is then fed into the inside of the first through hole 15 under pressure through the conveying channel 9. After passing through the first through hole 15, the material is fed into the inside of the connecting pipe 16. After being fed into the inside of the connecting pipe 16, the material is discharged through the second through hole 17, thus feeding the material to be tested into the inside of the electrospray head 7. The material can then be fed into the inside of the liquid inlet channel 18 through the third through hole 19. After passing through the liquid inlet channel 18, the material enters the inside of the connecting pipe 16 again and is output through the solenoid valve 21. Under the action of buoyancy, the floating sealing plug 20 moves to the top of the connecting pipe 16. The system seals the first through hole 15 and the second through hole 17, stopping the material feeding. Sensor 22 then detects any slight material overflow. When overflow is detected, cylinder 4 reverses and pulls the lifting plate 5, causing the feeding cylinder 6 to separate the contact head 8 from the extrusion head 14. Simultaneously, the reset spring 13 pushes the rubber sealing plug 11 in the opposite direction, resealing the feeding channel 9. The detected data is displayed on the monitor 2 for a more intuitive view. After material detection, air pump 28 generates suction, drawing the atomized material from the inside of the detector body 1 into the filter cylinder 29 via the suction pipe 27. The filter structure inside the filter cylinder 29 filters the atomized waste material in the air, and the filtered air is then discharged through the exhaust pipe 30 to prevent subsequent pollution of the surrounding air environment.
