烟具100还包括主控制电路板3和电池7。固定壳62包括前壳621与后壳622，前壳621与后壳622固定连接，主控制电路板3和电池7 均设置在固定壳62内，电池7与主控制电路板3电连接，按键4凸设在外壳61上，通过按压按键4，可以实现对基体111表面上的红外电热涂层112的通电或断电。主控制电路板3还连接有一充电接口31，充电接口31裸露于底盖64上，用户可以通过充电接口31对烟具100进行充电或升级，以保证烟具100的持续使用。
烟具100还包括隔热管16，隔热管16设置在固定壳62内，隔热管16设置在基体111的外围，隔热管16可以避免大量的热量传递到外壳61上而导致用户觉得烫手。隔热管包括隔热材料，隔热材料可以为隔热胶、气凝胶、气凝胶毡、石棉、硅酸铝、硅酸钙、硅藻土、氧化锆等。所述隔热管也可以包括真空隔热管。隔热管16内还可涂覆有红外线反射涂层，以将基体111上的红外电热涂层112发出的红外线反射回红外电热涂层112，提高加热效率。
烟具100还包括温度传感器，例如NTC温度传感器2，用于检测基体111的实时温度，并将检测的实时温度传输到主控制电路板3，主控制电路板3根据该实时温度调节流经红外电热涂层112上的电流的大小。具体的，当NTC温度传感器2检测到基体111内的实时温度较低时，譬如检测到基体111内侧的温度不到150℃时，主控制电路板3控制电池7输出较高的电压给电极，进而提高红外电热涂层112中馈入的电流，提高气溶胶形成基质的加热功率，减少用户抽吸第一口所要等待的时间。当NTC温度传感器2检测到基体111的温度为150℃-200℃时，主控制电路板3控制电池7输出正常的电压给电极。当NTC温度传感器2检测到基体111的温度在200℃-250℃时，主控制电路板3控制电池7输出较低的电压给电极；当NTC温度传感器2检测到基体111内侧的温度在250℃及以上时，主控制电路板3控制电池7停止输出电压给电极。
