Abstract

The invention discloses a household gas leakage alarm and automatic gas source cutoff device which comprises a gas leakage alarm assembly and an automatic gas source cutoff assembly. The gas leakage alarm assembly comprises a gas concentration testing box, and a gas-sensitive sensor is arranged in the gas concentration testing box and connected with a gas detection instrument. The gas leakage alarm assembly further comprises an intelligent control box, and an electronic circuit controller and an alarm device are arranged in the intelligent control box. The automatic gas source cutoff assembly comprises a linkage combiner. An electronic driver is arranged on the linkage combiner, and the signal output end of the gas-sensitive sensor is connected with the signal input end of the electronic driver. According to the device, indoor alarming and outdoor alarming are carried out at the same time, the gas concentration can be tested to give an alarm in time, a gas source can be automatically closed, and the device greatly reduces potential safety hazards of gas leakage, and has the advantages of being reliable in work, small in size, simple in structure and the like.

Description

technical field [0001] The invention relates to a gas leakage alarm device, in particular to an indoor and outdoor simultaneous gas leakage alarm and an automatic gas source cut-off device. Background technique [0002] With the development of society, people's material and cultural living standards have been significantly improved. As a household energy device to improve people's living conditions, gas stoves have been widely used in both urban and rural areas. The popularity of gas has improved production efficiency and the quality of life of citizens. However, in the process of using gas, accidents such as gas explosions and poisonings caused by gas leakage and exhaust gas have occurred from time to time, which has brought great harm to people's lives and property safety. Therefore, the safe use of gas has always been the top priority of the work of gas authorities. The gas leakage alarm can effectively monitor the concentration of combustible gas or toxic gas in the env...
