Fuel gas detector

The utility model discloses a fuel gas detector, it includes shell, filter element and gas sensitive sensor, the shell has the accommodation cavity and adsorption cavity, the accommodation cavity is sealed structure, the shell is provided with the intake port that is communicated with the adsorption cavity, the cavity wall of adsorption cavity is provided with a plurality of intake holes, the intake port is communicated with the adsorption cavity. Each air inlet hole is communicated with the accommodating cavity; the filtering piece is embedded in the adsorption cavity; and the gas sensitive sensor is arranged in the accommodating cavity. The gas-sensitive sensor has the beneficial effects that the gas-sensitive sensor has an oil smoke prevention function, and when the gas-sensitive sensor is used for detecting combustible gas in a kitchen, oil smoke is adsorbed by the filter piece and cannot enter the detector, so that the gas-sensitive sensor is prevented from being eroded by the oil smoke, and the service
