Combustible gas detector convenient to adjust and method

Abstract

The invention discloses a combustible gas detector convenient to adjust. The detector comprises: a fixed bracket provided with two clamping hooks, wherein a wire hole and a conductive terminal are disposed between the two clamping hooks; a main control base, wherein a main control board is installed on the main control base, an installation groove is formed in the front end face of the main control base, at least two conductive copper columns are arranged on the installation groove, a power connection port is formed in the main control base, fixing sliding grooves matched with the clamping hooks are formed in the back face of the main control base, and the back surface of the main control base is provided with a power connection sliding groove matched with the conductive terminal; and a detector, wherein connecting bulge is arranged on the main board of the detector, a plurality of semiconductor gas sensors are mounted on the main board, a transparent cover is mounted on the main board, and an activated carbon sheet is arranged on the inner side of the transparent cover. The invention further discloses a corresponding use method. According to the invention, the detection efficiency and accuracy of the detector are improved while flexible arrangement and later replacement and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of gas detection equipment, in particular to an easily adjustable combustible gas detector and method. Background technique [0002] When flammable gas leaks in the industrial environment and daily life environment (such as a kitchen using natural gas), and the flammable gas detector detects that the concentration of flammable gas reaches the alarm value set by the detector, the flammable gas detector will emit sound and light. Alarm signals to remind people to take safety measures such as evacuation, forced ventilation, shutdown of equipment, and various application scenarios. [0003] For ordinary consumers, combustible gas detectors are generally installed in the kitchen, and are set near the gas stove as needed. Existing detectors are generally fixed on the wall or tiles with bolts or suction cups, and it is very troublesome to replace them in the later stage; moreover, because the oil fume in daily use...

AI Technical Summary

Problems solved by technology

Existing detectors are generally fixed on the wall or tiles with bolts or suction cups, and it is very troublesome to replace them in the later stage; moreover, because the oil fume in daily use will accumulate on the sensor or the air inlet of the detector, the detection will be difficult after a long time. The sensitivity of the detector will decrease; in a ventilated environment or a closed environment, the layout of the detector is not perfect. In actual use, it is often necessary to detect the combustible gas after the concentration of the combustible gas exceeds a certain limit of the trigger threshold.
