[0002] A gas detector is an instrument used to detect specific gas components in the environment, and it is widely used in industrial production, environmental monitoring, and experimental research. Gas detectors can detect and analyze changes in the concentration of a gas in the air in real time, helping users to promptly detect leaks or abnormal concentrations, ensuring personnel safety and a stable production environment. In industries such as chemical, mining, and medical, gas detectors are an indispensable safety device.

[0003] To ensure the reliability and accuracy of gas detectors under various environmental conditions, they need to be tested in specific simulated environments. Simulation chambers, as an important tool for gas detector testing, can provide controllable gas concentration, pressure, and airflow environments to simulate various real-world application scenarios. Through simulation chamber testing, the sensitivity, response time, and stability of the gas detector can be effectively verified, ensuring its accurate and reliable operation in actual use.

[0004] However, existing simulation chambers often experience significant gas leakage when the gas detector is removed after testing. This leakage poses a safety hazard to operators, especially when detecting toxic or flammable gases, potentially leading to health risks or accidents. Furthermore, frequent air leaks affect the stability of the experimental environment, hindering the long-term use of the simulation chamber. Therefore, a new simulation chamber for gas detector testing is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a simulation box for testing gas detectors, aiming to improve the existing technology where, when the simulation box is opened after the test to remove the gas detector, a large amount of gas inside the box will leak, which can easily cause safety hazards and affect the stability of the experimental environment.

[0031] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a simulation box for testing a gas detector, comprising a box body 1, a box door 3 rotatably connected to the bottom of one side of the box body 1, a support plate 2 fixedly connected to the middle of the box body 1, an upper baffle 4 rotatably connected to the top surface of one side of the support plate 2, a lower baffle 5 rotatably connected to the bottom surface of one side of the support plate 2, a support platform 6 fixedly connected to one side of the bottom surface of the box body 1 for supporting the gas detector, a support bar 18 fixedly connected to one side of the inner wall of the box body 1, one side of the upper baffle 4 contacting the outer wall of the support bar 18, a support bar 29 fixedly connected to one side of the bottom surface of the inner wall of the box body 1, one side of the lower baffle 5 contacting the outer wall of the support bar 29, magnets are installed inside the lower baffle 5 and the support plate 2, and an adjustment component for adjusting airflow is installed in the middle of the bottom surface of the inner wall of the box body 1.

[0033] During testing, the upper baffle 4 is attached to the support plate 2, while the lower baffle 5 is attached to the support plate 2 via a magnet. After testing is completed, the upper and lower baffles 5 are rotated to contact the support bar 18 and support bar 19 respectively, dividing the internal space of the box 1 into an independent sealed small space and isolating the gas detector in the small space. Therefore, gas leakage from the large space can be avoided when the box door 3 is opened.

[0034] Reference Figures 1-5 The adjustment assembly includes a partition 15, which is rotatably connected to the inner bottom of the housing 1. A lever 14 is fixedly connected to the middle of one side of the partition 15, and the lever 14 is located outside the housing 1. A locking rod 16 is rotatably connected to the outer side of the middle of one side of the partition 15, and a pull rod 17 is fixedly connected to one side of the locking rod 16.

[0035] The rotation of the lever 14 drives the partition 15 to rotate, which in turn pulls the lever 16 and the pull rod 17, thereby simultaneously driving multiple partitions 15 to rotate. This allows for more precise airflow adjustment inside the chamber 1, flexibly controlling the direction and flow of airflow to adapt to the needs of different testing environments.

[0036] Reference Figures 1-3An air inlet pipe 7 is fixedly connected to one side of the top surface of the housing 1, and a valve is installed inside the air inlet pipe 7. A pressure gauge 8 is fixedly connected to the other side of the top surface of the housing 1. A slot 9 is provided at the bottom of one side of the housing 1. A sealing ring is provided on one side of the door 3, and the sealing ring is located inside the slot 9. A handle is installed on the other side of the door 3.

[0037] By using the air inlet pipe 7 and valve, the inflow rate and timing of gas can be controlled, so as to precisely adjust the gas environment inside the chamber 1 during the test. The pressure gauge 8 can monitor the gas pressure inside the chamber 1 in real time to ensure that the gas concentration and pressure meet the test requirements and avoid affecting the test results due to insufficient gas or excessive pressure.

[0038] Reference Figures 1-3 A slot 9 is provided at the bottom of one side of the chamber 1. The slot 9 is used to embed the sealing ring on one side of the chamber door 3 to form a reliable sealing effect, preventing gas from leaking from the chamber door 3 during the test, and ensuring the stability of the internal environment of the chamber 1 and the accuracy of the gas detector's detection data. A handle is installed on the other side of the chamber door 3, which makes it convenient for operators to open and close the chamber door 3, improving the convenience and efficiency of operation.

[0039] Reference Figures 1-3 A groove 10 is provided on one side of the top surface of the support plate 2, and the upper baffle 4 is located inside the groove 10. A fan 11 is installed on one side of the bottom surface of the support plate 2, and the fan 11 is used to drive airflow.

[0040] The upper baffle 4 can be stored in the groove 10, and the air inside the chamber 1 can be driven by the fan 11 to promote the uniform distribution of gas inside the chamber 1. Driven by the airflow of the fan 11, the incoming test gas can be quickly mixed to ensure that the gas concentration in each area inside the chamber 1 is consistent, providing a stable and uniform detection environment for the gas detector.

[0041] Reference Figures 1-5 A lever 12 is fixedly connected to the bottom of the upper baffle 4, and the lever 12 is located outside the housing 1. A lever 2 13 is fixedly connected to the top of the lower baffle 5, and the lever 2 13 is located outside the housing 1.

[0042] The upper baffle 4 and lower baffle 5 can be easily rotated by lever 12 and lever 13, improving the convenience of use.

[0043] Working Principle: In use, first keep the upper baffle 4 and lower baffle 5 in initial contact with the support plate 2. At this time, the lower baffle 5 contacts the support plate 2 through the attraction of a magnet. Then, open the door 3 to ensure unobstructed access for placing the gas detector. After placing the gas detector on the support 6, close the door 3 and ensure the sealing ring is embedded in the groove 9 at the bottom of the chamber 1 to form a good seal and prevent subsequent gas leakage. Then, add the detection gas through the inlet pipe 7, and then open the valve to allow the gas to flow into the chamber 1. Observe the internal gas pressure through the pressure gauge 8 on the top of the chamber 1 to ensure that the required test gas pressure is reached, avoiding insufficient gas or excessive pressure. Then, close the valve. The fan 11 then drives the airflow inside the chamber 1, making the gas evenly distributed inside the chamber 1, creating a uniform detection environment for the gas detector. During detection, the fan 11 rotates... The movable lever 14 can drive a partition 15 to rotate. At this time, the partition 15 will pull the lever 16 and the pull rod 17 and drive multiple partitions 15 to rotate simultaneously. This can adjust the direction and path of the airflow inside the chamber 1, control the airflow distribution, and simulate different gas flow environments. When two adjacent partitions 15 come into contact with each other, the gap between them can be reduced, thereby adjusting the airflow rate. After the test is completed, in order to prevent gas leakage in the large space, the lever 12 and lever 23 are rotated in sequence. After rotating lever 12, the upper baffle 4 will come into contact with the support bar 18. After rotating lever 23, the lower baffle 5 will come into contact with the support bar 29. At this time, the upper baffle 4, the support bar 2, and the lower baffle 5 can divide the inside of the chamber 1 into a small sealed space. At this time, the gas detector is also located in the small space. Finally, the chamber door 3 is opened, the gas detector is taken out, and the chamber door 3 is closed.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
