[0003] A combustible gas monitoring device is a device used to detect and monitor the concentration of combustible gases in the environment. The main function of a combustible gas monitoring device is to detect the concentration of combustible gases in the environment in real time and accurately. It can continuously monitor combustible gases in specific areas (such as industrial workshops, petrochemical sites, near gas pipelines, underground mines, etc.). However, existing combustible gas monitoring devices are not convenient for actively and efficiently acquiring gas samples from the environment, resulting in monitoring lag and making it easy to miss the critical period of combustible gas leakage. In addition, impurities can easily enter the monitoring components during the use of most devices, affecting the monitoring accuracy and the service life of the equipment. Furthermore, the existing collection structure is often inconvenient to install and disassemble, which is not conducive to the collection and delivery of gas samples for testing. During periodic inspections or troubleshooting, the operation is cumbersome and time-consuming. Utility Model Content

In addition, impurities can easily enter the monitoring components during use, affecting the monitoring accuracy and equipment lifespan. Furthermore, existing collection structures are often inconvenient to install and disassemble, which is not conducive to the collection and delivery of gas samples for testing. During regular spot checks or troubleshooting, the operation is cumbersome and time-consuming.

At the same time, its snap-fit ​​design facilitates disassembly, cleaning, and replacement. The interception component 3 at the bottom of the air inlet duct 5 can initially intercept foreign objects from the outside, enhancing the filtration effect. The monitoring structure 6 can accurately monitor combustible gases.

Figure 3 A pull rod 9 is bolted to the front of the locking block 203, and a pull plate 10 is bolted to the front of the pull rod 9. In this embodiment, by setting the pull rod 9 and the pull plate 10, a convenient operation method is provided for disassembling the dust filter mechanism 2. The operator only needs to pull the pull plate 10 to drive the locking block 203 through the pull rod 9, thereby easily removing the dust filter frame 201 and the filter screen 202 from the air inlet duct 5 without the need for other complicated tools, which greatly improves the convenience and efficiency of maintenance and saves time and labor costs.

The bottom of the transmission pipe 11 is fixedly connected to a first distribution pipe 12, the bottom of which is fixedly connected to the top of the monitoring structure 6. A first valve 13 is provided on the surface of the first distribution pipe 12. In this embodiment, by setting the transmission pipe 11, the first distribution pipe 12, and the first valve 13, the transmission pipe 11 at the top of the air pump 4 is fixedly connected to the inner wall of the monitoring box 1, and the first distribution pipe 12 at the bottom is fixedly connected to the top of the monitoring structure 6. The first valve 13 is provided on the surface of the first distribution pipe 12. This arrangement allows the gas drawn by the air pump 4 to be stably transmitted through the transmission pipe 11, and the gas flow to the monitoring structure 6 can be controlled by the first valve 13, realizing the orderly delivery and precise distribution of gas. This facilitates the monitoring structure 6 to detect the gas, improves the accuracy and reliability of monitoring, and also facilitates the adjustment and control of gas flow rate.

[0034] Additionally, please refer to Figure 5 The bottom of the transmission pipe 11 is fixedly connected to a second distribution pipe 14, and the bottom of the second distribution pipe 14 is fixedly connected to the top of the monitoring structure 6.

The second valve 15 is provided on its surface. In cooperation with the first distribution pipe 12, multi-path control of gas delivery to the monitoring structure 6 can be realized. According to different monitoring needs or working conditions, the gas delivery path can be flexibly selected, which increases the flexibility and adaptability of the monitoring structure 6. For example, in different parts of the monitoring structure 6 or in different monitoring modes, the gas can be controlled to enter the corresponding monitoring area through the first valve 13 and the second valve 15 respectively, thereby improving the comprehensiveness and effectiveness of monitoring.

[0035] Additionally, please refer to Figure 5 A filter cover 16 is threaded onto the surface of the transmission pipe 11, and a third valve 17 is provided on the surface of the transmission pipe 11. In this embodiment, by providing the filter cover 16 and the third valve 17, the filter cover 16, which is threaded onto the surface of the transmission pipe 11, can prevent foreign objects from entering the transmission pipe 11, while the third valve 17 can independently control the opening and closing of the transmission pipe 11, facilitating gas collection and discharge.

[0036] Additionally, please refer to Figure 2A leak-proof monitoring component 18 is bolted to the inner wall of the monitoring box 1, and an alarm component 19 is bolted to the top of the monitoring box 1. In this embodiment, by setting the leak-proof monitoring component 18 and the alarm component 19, the leak-proof monitoring component 18 bolted to the inner wall of the monitoring box 1 can monitor in real time whether there is a gas leak inside the monitoring box 1. Once a leak is detected, it can promptly send a signal.
