Description

Household combustible gas detector Technical Field The utility model relates to the technical field of combustible gas detector equipment, in particular to a household combustible gas detector. Background The gas detector is an instrument for detecting the concentration of gas, which is suitable for dangerous places with combustible or toxic gas and can continuously detect the content of the detected gas in the air within the explosion lower limit for a long time. The combustible gas detector is installed in a household kitchen at present more and more, and whether gas leakage exists or not can be detected, so that the household safety can be improved, but the household combustible gas detector in the prior art is often simply subjected to induction operation, and corresponding reaction cannot be carried out according to the induction result. Disclosure of utility model The technical problem to be solved by the utility model is to provide the household combustible gas detector aiming at the defects in the background technology. In order to solve the technical problems, the technical scheme provided by the utility model is that the household combustible gas detector comprises a fixed mounting frame, wherein the bottom of the fixed mounting frame is provided with a controller, the bottom of the controller is provided with a combustible gas detection structure, the bottom of the combustible gas detection structure is provided with a first combustible gas detector, the top of the fixed mounting frame is provided with a gas collecting cover, and the fixed mounting frame is provided with an air inlet communicated with the inside of the gas collecting cover; An exhaust fan is arranged in the gas-collecting hood, and an exhaust pipeline extending to the outside is arranged at the top of the gas-collecting hood; the combustible gas detection structure comprises an external sealing shell, a second combustible gas detector is arranged in the external sealing shell, and exhaust fans are arranged at two ends of the external sealing shell. Further, the air inlet in be equipped with first filter screen structure, exhaust duct on be equipped with the check valve structure, conveniently filter impurity and prevent gaseous refluence. Furthermore, the air collecting pipeline matched with the exhaust fan is arranged at the two ends of the external sealing shell, and the electric control valve is arranged on the air collecting pipeline, so that the internal sealing operation of the external sealing shell is conveniently ensured. Further, the bottom of the combustible gas detection structure is provided with a cylinder which is used for annularly wrapping the first combustible gas detector, and the bottom of the cylinder is provided with a second filter screen structure, so that the first combustible gas detector can be protected daily. Furthermore, the buzzer and the warning lamp are respectively arranged on two sides of the controller, so that the buzzer warning and the warning lamp warning operation can be performed. Compared with the prior art, the household combustible gas detector has the advantages that the combustible gas detector and the exhaust structure in the sealing state are additionally arranged on the basis of the traditional combustible gas detector, so that the detection accuracy can be ensured, and meanwhile, the timely exhaust operation after detection can be ensured.
