[0016] The present utility model will be specifically described below with reference to the attached drawings. As shown in the attached drawings Figure 1 and the attached Figure 2 shown, an Internet of Things combustible gas detector includes a detector housing 1. A display module 11 is fixedly installed on the upper side of the front part of the detector housing 1. A button module 12 is fixedly installed on the lower side of the front part of the detector housing 1. A main control board 13 is fixedly installed inside the detector housing 1. Gas sensors 14 are fixedly installed inside the installation pipes integrally provided on the front and rear sides on the left side of the lower part of the detector housing 1. A detection tube assembly 2 is installed between the installation pipes integrally provided on the front and rear sides on the left side of the lower part of the detector housing 1.

[0017] In this embodiment, as shown in the attached Figure 3 drawing, the detection tube assembly 2 includes a fan 21. The fan 21 is an EX increased safety type small explosion-proof fan. A gas collecting hood 22 is fixedly and sealedly installed at the air outlet end of the fan 21. A three-way pipe 23 is fixedly installed at the air outlet of the gas collecting hood 22. Gas valves 24 are installed in the pipeline at both air outlet ends of the three-way pipe 23. The gas valves 24 are solenoid valves. The air outlet end of the gas valve 24 is connected to a detection tube 25 through a pipeline. The detection tube 25 is a three-way steel pipe. The upper ends of the two detection tubes 25 are respectively flange-connected to the installation pipes integrally provided on the front and rear sides on the left side of the lower part of the detector housing 1. When detecting combustible gas, the fan 21 provides power for the air flow. One of the gas valves 24 is turned on and the other gas valve 24 is turned off. The gas enters the detection tube 25 through the opened gas valve 24. The gas is detected by the gas sensor 14. When it is necessary to repair one of the gas sensors 14, the detection can be carried out through the other gas sensor 14, ensuring the continuity of gas detection.

[0018] In this embodiment, specifically, the display module 11, the button module 12, the gas sensor 14, the fan 21, and the gas valve 24 are all electrically connected to the main control board 13.
