The inner wall of the sensor mounting bin 7 is sleeved with the outer surface of the combustible gas detection sensor 6, and the inner side of the sensor mounting bin 7 is sleeved with the inner wall of the one side of the inside of the lower shell 1.
[0027] The lower shell 1 satisfies the installation of the communication board 5 and the main board 2 structure, and provides an external isolation protection environment. The communication board 5 is used for communication. The combustible gas detection sensor 6 adopts a semiconductor type and is mainly composed of a heating loop, a load loop and a power supply loop. The semiconductor device is heated to stability by the heating loop. When the combustible gas contacts the sensor, the conductivity of the sensor will increase with the increase of the concentration of the combustible gas, forming an output signal proportional to the concentration of the combustible gas. The sensor mounting bin 7 is used for mounting the combustible gas sensor.
[0028] The sensor structure further comprises a main board 2, an upper shell 3, a nameplate 4 and a fastening screw 10.
