[0002] In many fields such as industrial production and gas storage, the use and presence of combustible gas are inevitable. However, once the combustible gas leaks and reaches a certain concentration, it may trigger serious safety accidents such as fires and explosions, posing a great threat to people's lives and property. With the progress of technology, combustible gas detection equipment has gradually emerged. These equipment usually consist of a detection device housing and sensors and other structures. In the field of household kitchens, when in use, the detection device housing is usually fixedly installed on the wall, and the sensor is usually installed inside the housing. The sensor is used to detect whether the combustible gas in the kitchen leaks. When the equipment needs to be repaired or replaced, since the equipment is fixedly installed on the wall, it is inconvenient to disassemble and install the equipment, increasing the workload of maintenance personnel and reducing the work efficiency of maintenance personnel to a certain extent. In order to solve the deficiencies of the prior art, we propose a combustible gas detection and pre - warning equipment. Content of the Utility Model
