The invention relates to an unmanned aerial vehicle-mounted gas detector, which comprises a gas detector mounted on an unmanned aerial vehicle, and the gas detector comprises: a housing having a gas inlet and a tail hole; the electromagnetic ejection air interchanger is arranged at the air inlet of the shell and comprises an electromagnetic coil, and the electromagnetic coil is powered on and powered off to open and close the air inlet; the gas sensor is installed in the shell and located on a gas flowing path sampled after switching of the electromagnetic ejection ventilation device; the capacitor driving module is connected with the electromagnetic coil and is used for controlling on-off and current direction of the electromagnetic coil; based on the characteristics of capacitor storage and instant electric energy release, magnetic ejection type driving of the electromagnetic ejection ventilation device is achieved by combining the electromagnetic principle. The unique driving mode is different from a traditional mechanical or pure electromagnetic driving air interchanger, and the size of the air interchanger is obviously reduced.
