摘　　要：提出了一种由气敏传感器和热敏传感器相结合的电路设计。本装置通过由MQ-N10传感器和热敏传感器采集油烟信号并转变为电压信号,经过集成非门推动三极管电路,处理后由继电器控制电机启动运转,实现煤气泄漏警告和油烟的抽排。比普通抽油烟机寿命长3～4倍。This paper put forward a circuit design which combines gas sensor and thermal sensor. The device converts the smoke signal collected by the MQ-N10 sensor and thermal sensor into voltage signals. After processing the signal by the integrated gate drive three transistor circuit, the motor is switched on by the relay, realizing the alarm of gas leak and the remove of airborne grease, combustion products, smoke, odors, heat, and steam from the air by evacuation. This kind of range hood, whose lifespan is 3 to 4 times longer than ordinary ones.
