Abstract

The invention discloses a fuel gas alarm device which comprises a central mainboard, a fuel gas detection module, a flame detection module, an electromagnetic valve module and a sound-light alarm module are all connected with the central mainboard, and the electromagnetic valve module is arranged on a fuel gas pipeline; the fuel gas detection module is used for collecting a fuel gas flowing state in a fuel gas pipeline and outputting and sending a first electric signal; the flame detection module is used for collecting cooking range flame information of the gas stove and outputting and sending a second electric signal; the central main board is used for outputting and sending an electromagnetic valve opening and closing instruction and an alarm instruction according to the received first electric signal and second electric signal; the electromagnetic valve module is used for responding to the received electromagnetic valve opening and closing instruction and executing an opening action or a closing action; the sound-light alarm module is used for responding to the received alarm instruction and executing a sound-light alarm action; the device has the advantages of being high in detection precision, long in service life and free of repeated calibration.

Description

technical field [0001] The invention belongs to the technical field of gas leakage alarm devices, in particular to a gas alarm device. Background technique [0002] At present, in the process of using pipeline gas, there is often a possibility of leakage; when gas leaks in the indoor air, if it is not detected in time and the gas is diffused to the outside, dangerous situations such as gas explosion are likely to occur, seriously endangering people's lives and property. Safety. [0003] Most of the traditional gas alarms use the gas around the gas alarm to be inhaled into the alarm, and use the inhaled gas to produce a chemical or electrochemical reaction with the sensor surface in the alarm to change the electrical and physical characteristics of the sensor, thereby issuing an audible and visual alarm; therefore , When the alarm is issued, the gas in the indoor air has reached a high concentration, and the alarm has a serious hysteresis; at the same time, due to the comple...
