AI Technical Summary
Existing trace oxygen analyzers lack effective quantitative gas intake, which makes them prone to malfunctions under electronically controlled quantitative gas intake, affecting the long-term stable use of the device.
The connecting rod and piston system, designed using the lever principle, controls the gas to enter the collection tank through a negative pressure machine, uses a moving plate to close the air inlet to achieve quantitative air intake, and drives the piston back to its original position through a hydraulic cylinder to ensure the consistency of the air intake each time.
This achieves stability in physical quantitative gas intake, reduces the impact of electronic control component failures, and improves the stability of gas detection and the reliability of detection values.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen composition detection, and in particular to a trace oxygen analysis device. Background Technology
[0002] A trace oxygen analyzer is a device used to measure the concentration of trace amounts of oxygen in air or other gases. It typically includes a sensor, a sampling system, and a data processing unit, and is capable of accurately measuring the oxygen content in a gas. It is commonly used in laboratories, industrial production, and environmental monitoring.
[0003] While existing technologies can achieve certain oxygen composition detection and analysis effects, they suffer from the following drawback: the lack of effective quantitative gas intake in current trace oxygen analyzers leads to malfunctions when combined with electronic control and quantitative gas intake, affecting the long-term stable operation of the device. In view of this, we propose a trace oxygen analyzer that solves the above problems. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a trace oxygen analysis device.
[0005] The technical solution of this utility model is as follows: A trace oxygen analysis device includes a housing, a mounting groove, and a collection groove. The collection groove is provided on one side of the housing, and the mounting groove is provided on one side of the collection groove. An air inlet is provided on one side of the housing. A movable plate is movably installed inside the air inlet. A connecting rod two is rotatably installed inside the mounting groove. A connecting rod one is provided on one side of the connecting rod two. The connecting rod one, the connecting rod two, and the movable plate are connected by a lever design. A piston is movably installed inside the collection groove. The connecting rod one is fixedly connected to one side of the piston. An oxygen detector is provided inside the housing.
[0006] When this device is in use, gas enters through the inlet under the operation of a negative pressure compressor. At this time, control valve one is closed and control valve two is open. Gas then enters through the inlet and fills the collection tank. As the gas volume increases, the piston moves to one side under pressure. Utilizing the lever principle of connecting rod one, connecting rod two, and the moving plate, the moving plate closes the inlet, ensuring that the gas intake volume and pressure remain at a certain value. Then, control valve one is activated and control valve two is closed, allowing the gas to enter the oxygen detector for detection. The information is then displayed at the top of the screen. After detection, the hydraulic cylinder drives the baffle to push connecting rod one back to one side, causing the piston and moving plate to return to their original positions, allowing for the next gas sample injection. This device has a physical quantitative gas intake effect, which is more stable than the quantitative processing effect of a metering valve, reducing the impact of uncertain factors on the stability of gas detection.
[0007] Preferably, a base is fixed to the lower end of the enclosure, a heat dissipation vent is provided on one side of the outer wall of the enclosure, a display screen is provided on one side of the outer wall of the enclosure, and a control panel is provided on one side of the display screen.
[0008] Preferably, a wiring port is provided on one side of the outer wall of the box, and protective pads are glued to the four corners of the upper end of the box.
[0009] Preferably, a control valve one is fixed to the inner wall of one side of the collection tank, and a control valve two is fixed to one side of the control valve one. The control valve one is connected to the oxygen detector.
[0010] Preferably, a negative pressure machine is provided on one side of the collection tank, and the negative pressure machine is connected to the control valve.
[0011] Preferably, a telescopic rod 1 is inserted into the side of the connecting rod 2 facing the connecting rod 1, and the telescopic rod 1 is rotatably connected to the connecting rod 1. A telescopic rod 2 is inserted into the side of the connecting rod 2 facing the moving plate, and the telescopic rod 2 is rotatably connected to the side of the moving plate.
[0012] Preferably, a hydraulic cylinder is provided on one side of the mounting groove, a hydraulic rod is inserted into one side of the hydraulic cylinder, and a baffle is fixed on one side of the hydraulic rod. The hydraulic cylinder can drive the baffle to push the connecting rod to make the piston return to its original position.
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] I. When using this utility model, it can utilize the effect of metered gas intake to achieve metered gas intake and sealing effect through physical means. Its operation is relatively stable and can reduce the problem of device malfunction caused by electronic control component failure.
[0015] Second, based on the first beneficial effect, this device uses mechanical means to realize the return of the moving plate, so that the space of the collection tank returns to the original set size, and the air intake volume reaches a certain value each time. This can achieve the singleness of the air intake index for component detection, making the final detection value more convincing.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
