其中，附图标记：1-控制电路板固定件，2-控制电路板，3-按键，4-控制组件外壳。
 本发明的最佳实施方式
本发明下面将结合附图作进一步详述：
请参阅图1所示， 所述 带有双电压输出的电子烟控制组件包括控制电路板固定件 1 、控制电路板 2 和控制组件外壳 4 ；控制电路板 2 上布设二个微触开关 K 1 、 K 2 ，而控制组件外壳 4 对应位置配合设有按键 3 ，按键 3 和微触开关 K 1 、 K 2 一起构成按键开关，按下按键 3 的不同位置分别控制微触开关 K 1 和 K 2 。
第二，说明本发明优选实施例的电路和工作原理：
请参阅图2、图3所示， 包括开关 K 1 、 K 2 ，指示灯 D 1 、 D 2 、 D 3 ，主控芯片 U 1 ，电源管理芯片 Q 8 、电压检测单元 R 9 +R 10 、输出开关 Q 4 +Q 5 +Q 6 以及其他辅助电路， BT+ 端接电池， F+ 端接电阻丝。
该电路工作原理具体是：
（一）大烟雾输出
当开关 K 1 闭合时，产生 KEY 1 信号，指示灯 D 1 亮白灯，同时根据电芯自身的电压， U 1 芯片 8 脚输出的脉宽占空比为宽 PWM 信号，电源管理模块 Q 8 接收到 PWM 信号后，从 Q 8 的第 2 、 5 脚输出对应的电压控制波形，使电源经过电感 L 、续流二极管 D 4 产生约 4.0V 恒定电压输出，然后由 U 1 发出开的信号 HOT, 控制三极管 Q 4 ，三极管 Q 4 给出驱动信号控制场效应管 Q 5 和 Q 6 ，使 Q 5 和 Q 6 接通，使约 4.0V 恒定电压输出到Ｆ + 端给发热丝，此时发热丝有大电流通过，并产生大烟雾。
（二）小烟雾输出
当开关 K 2 闭合时，产生 KEY 2 信号，指示灯 D 3 亮蓝灯，同时根据电芯自身的电压， U 1 芯片 8 脚输出的脉宽占空比为窄 PWM 信号，电源管理模块 Q 8 接收到 PWM 信号后，从 Q 8 的第 2 、 5 脚输出对应的电压控制波形，使电源经过电感 L 、续流二极管 D 4 产生约 3.5V 恒定电压输出，然后由 U1 发出开的信号 HOT, 控制三极管 Q 4 ，三极管 Q 4 给出驱动信号控制场效应管 Q 5 和 Q 6 ，使 Q 5 和 Q 6 接通，使约 3.5V 恒定电压输出到Ｆ + 端给发热丝，此时发热丝有小电流通过，并产生小烟雾。
（三）短路保护
在吸烟或者充电过程中， F+ 端与地之间如果出现短路现象； U 1 芯片的 VDD_AD 管脚取样为低电平， U 1 的 HOT 控制脚输出低电平， Q 5 、 Q 6 不工作无输出，同时指示灯 D 2 会闪红灯报警。
（四）关闭输出
如果同时按住按键 3 二端，开关 K 1 和 K 2 同时闭合， U 1 芯片扫描发现 KEY 1 和 KEY 2 同时接地，则不发出 PWM 信号，不会进行吸烟模式，属于输入指令无效状态； U 1 芯片 HOT 脚同时发出关的信号 , 控制三极管 Q 4 ，三极管 Q 4 给出信号控制 Q 5 和 Q 6 ，使 Q 5 和 Q 6 断开。
（五）充电
当电芯需要充电时，接上充电器(至Ｆ + 端)， U 1 芯片的 VDD_AD 端检测到有高电平，通过 CH_EN 管脚输出信号控制场效应管 Q2 和 Q3 闭合，系统进入充电状态。当电芯到饱和状态时， U 1 芯片的 VDD_AD 端检测到有低电平，通过 CH_EN 管脚输出信号控制 Q 2 和 Q 3 断开，系统停止充电。
