Description

Technical Field

[0001] This application belongs to the field of analytical instrument manufacturing technology, specifically a combustion chamber used in ICP equipment to ensure the position of the light source for observation. Background Technology

[0002] Currently, most ICP equipment uses either a fixed or two-dimensional adjustable light source design. The fixed design places certain requirements on the torch position and the dimensions of the high-frequency coil. If the flame position at the center of the torch is not perpendicular to the lens barrel, the intensity of the light signal acquisition will be reduced. Furthermore, the formation of the ICP flame generates a large amount of exhaust gas and heat, requiring a corresponding exhaust system at the top to discharge these gases and heat. Currently, most systems on the market use direct exhaust, with fans drawing the exhaust air. This direct treatment method can cause the airflow in the combustion chamber due to the fan's suction. Excessive exhaust volume can cause flame vibration, while insufficient exhaust volume can lead to insufficient discharge of exhaust gas and heat, resulting in overheating of the combustion chamber. Therefore, a combustion chamber design is needed that allows for stable flame position adjustment and is suitable for ICP equipment. Summary of the Invention

Detailed Implementation

[0014] like Figure 1-10 As shown, a combustion chamber for ensuring the observation position of the light source in an ICP device includes a support 1 and a housing 2. The housing 2 is mounted on the support 1. A through hole is provided on the rear side wall of the housing 2. A spatial coordinate position adjuster is provided on the support 1 on the rear side of the housing 2. An RF high-frequency coil 3 and a clamping hand 15 cooperating with the RF high-frequency coil 3 are provided on the spatial coordinate position adjuster. The actuating end of the RF high-frequency coil 3 extends into the housing 2 through the through hole. A uniform flow exhaust port is provided on the top of the housing 2.

[0015] In this embodiment, the spatial coordinate position adjuster of this application adjusts the optimal observation position of the light source in three directions: horizontal, vertical, and left-right. Simultaneously, the uniform flow exhaust port design ensures that exhaust gas is drawn out and discharged more smoothly from the combustion chamber, guaranteeing the stability of the flame environment. The clamping hand 15 is used to hold the torch tube, and the RF high-frequency coil 3 is used to generate a flame in the torch tube. During use, the detector's lens is positioned at the front of the housing 2 to observe the flame.

[0016] In a preferred embodiment, the spatial coordinate position adjuster includes a first servo motor 4, a first track 5, a first support plate 6, a second servo motor 7, a second track 8, a second support plate 9, and a lifting adjuster. The first servo motor 4 is fixedly mounted on the bracket 1. The first support plate 6 is fixedly mounted on the bracket 1. The first track 5 and the first servo motor 4 are fixedly mounted on the first support plate 6. The first track 5 is parallel to the upper surface of the bracket 1. A first slider 10 is slidably connected between the two ends of the first track 5. The second support plate 9 is fixedly connected to the first slider 10. A first support leg 11 is provided on the lower surface of the second support plate 9 at a distance away from the first slider 10. The first support leg 11 has a first internal threaded hole. The axis of the first internal threaded hole is parallel to the first track 5. A first lead screw 12 is coaxially fixedly connected to the output shaft of the first servo motor 4. The two ends of the first lead screw 12 are connected to the first internal threaded hole. The first lead screw 12 is parallel to the first slide rail 5. The second support plate 9 is parallel to the upper surface of the bracket 1. The upper surface of the second support plate 9 is fixedly provided with a second slide rail 8 and a second servo motor 7. The second slide rail 8 is parallel to the second support plate 9 and perpendicular to the first slide rail 5. The two ends of the second slide rail 8 are slidably connected to a second slider 13. The second slider 13 is fixedly connected to a third support plate 14. The lower surface of the third support plate 14 is provided with a second foot away from the second slider 13. The second foot is provided with a second internal thread hole. The output end of the second servo motor 7 is coaxially fixedly connected to a second lead screw. The two ends of the second lead screw are engaged with the second internal thread hole. The second lead screw is parallel to the second slide rail 8. The upper surface of the third support plate 14 is provided with a lifting adjuster. The execution end of the lifting adjuster is provided with an RF high-frequency coil 3 and a clamping hand 15. With this setup, the first servo motor 4 drives the first lead screw 12 to rotate, thereby driving the first slider 10 to move on the first track 5. The movement of the first slider 10 causes the second support plate 9 to move. At this time, the third support plate 14, the lifting adjuster, the RF high-frequency coil 3, and the clamping hand 15 cooperating with the RF high-frequency coil 3, located on the second support plate 9, will also move on the first track 5. Meanwhile, the second servo motor 7 drives the second lead screw 33 to rotate, thereby driving the second slider 13 to move, which in turn drives the third support plate 14 to move. The lifting adjuster, the RF high-frequency coil 3, and the clamping hand 15 cooperating with the RF high-frequency coil 3 on the third support plate 14 will then move on the second track 8. If the first track 5 is defined as the X-axis in the spatial coordinate system, then the second track 8 is the Y-axis in the spatial coordinate system, and the lifting adjuster is the Z-axis in the spatial coordinate system. They respectively adjust the spatial position of the RF high-frequency coil 3 and the clamping hand 15 cooperating with the RF high-frequency coil 3, thereby enabling the flame on the torch tube to reach the optimal observation position.

[0017] In a preferred embodiment, the lifting adjuster includes a third servo motor 16, a third slide rail 17, a fourth slide rail 18, a spring 30, a first inclined block 20, and a second inclined block 21. The third servo motor 16 is fixedly mounted on the third support plate 14. The third slide rail 17 is fixedly mounted on the third support plate 14 and is parallel to the third support plate 14. The third slide rail 17 is parallel to the connecting line segment between the front and rear ends of the housing 2. The output shaft of the third servo motor 16 is parallel to the third slide rail 17. A third slider 22 is slidably mounted between the two ends of the third slide rail 17. A fourth support plate 18 is fixedly mounted on the third slider 22. A third support foot is provided on the lower surface of the fourth support plate 18. The third support foot is provided with a third internal threaded hole that mates with the two ends of the third lead screw 32. A first inclined block 20 is fixedly mounted on the upper surface of the fourth support plate 23. A fifth support plate 34 is located on the lower surface of the fifth support plate 34. The surface is provided with a second inclined block 21 that mates with the first inclined block 20. A first connecting plate 24 is vertically provided on the side wall of the fifth support plate 34. A second connecting plate 25 is vertically provided on the side wall of the third support plate 14. A first sliding groove 27 is vertically provided on the first connecting plate 24. A fourth sliding rail 18 that mates with the first sliding groove 27 is vertically provided on the second connecting plate 25. One end of the inclined surface of the first inclined block 20 faces the front side of the housing 2, and the other end faces the rear side of the housing 2. One end of the inclined surface of the second inclined block 21 faces the front side of the housing 2, and the other end faces the rear side of the housing 2. A second protrusion 28 is provided on the inclined surface of the first inclined block 20. The second protrusion 28 is parallel to the length line of the inclined surface of the first inclined block 20. A second sliding groove 29 that mates with the second protrusion 28 is provided on the inclined surface of the second inclined block 21. The second sliding groove 29 is parallel to the length line of the inclined surface of the second inclined block 21. With this configuration, the third motor 16 drives the third lead screw 32 to rotate, which in turn drives the first inclined block 20 to move along the third slide rail 17. Since the second inclined block 21 cooperates with the first inclined block 20, the movement of the first inclined block 20 will cause the fifth support plate 34 located on the second inclined block 21 to move up and down. The RF high-frequency coil 3 and the clamping hand 15 cooperating with the RF high-frequency coil 3 are fixed on the fifth support plate 34, so they will drive the RF high-frequency coil 3 and the clamping hand 15 cooperating with the RF high-frequency coil 3 to move up and down. The RF high-frequency coil 3 is used to move the torch tube held by the clamping hand 15 up and down, thereby causing the flame generated on the torch tube to move up and down, thus adjusting the position of the flame on the Z-axis in the spatial coordinate system. The cooperation between the first connecting plate 24 and the second connecting plate 25 ensures that the second inclined block 21 will not move along the third slide rail 17 when the first inclined block 20 moves.

[0018] As a preferred embodiment, one end of the spring 30 is fixedly connected to the side wall of the third support plate 14, and the other end of the spring 30 is fixedly connected to the side wall of the fifth support plate 34. The spring 30 ensures the stability of the movement between the first inclined block 20 and the second inclined block 21.

[0019] As a preferred embodiment, the uniform flow exhaust vent comprises a plurality of vent units 31, wherein the distance between any two adjacent vent units 31 is less than the radius between individual vent units 31, and the length of each vent unit 31 is greater than its diameter. This arrangement allows heat and exhaust gas to be discharged smoothly from the exhaust housing 2, thus preventing airflow within the housing 2 and flame flickering when the exhaust volume is too large.

[0020] As a preferred embodiment, the length of each of the air vent units 31 is more than five times the diameter of the air vent unit 31.

[0021] As a preferred embodiment, the projection of the vent unit 31 onto the top wall of the housing 2 is a regular hexagon. This hexagonal design allows for a smoother discharge of exhaust gas within the housing 2. Figure 10 As shown, if designed as a square or circle, a region B without negative pressure would be formed between each column or row. This region would be very long, leading to instability. However, the hexagonal design, like a honeycomb, ensures that region B is curved and not too long, thus better ensuring stable exhaust gas discharge and preventing flame flickering.
