如图5所示，本实用新型提供的电子吸烟装置，还可包括充电保护电路23、电子开关25、温度采样电路27和加热控制电路28。充电电路21、调压电路22、充电保护电路23和储能电池24顺次级联，储能电池24为加热电路26和加热控制电路28供电，电子开关25可通过两种方式实现加热电路26的通断，一种是加热控制电路28向电子开关25施加信号控制其接通或关断，一种是用户人为的触发来控制其开机或关机。
本实用新型装置中包括至少一块储能电池24，一般来说是锂电池，通常越200mAh-2200mAH，但是不限于锂电池，也可选择其他类型储能电池；充电电路21通常与输出电压为5V-24V的外部充电设备连接，采用恒定电压给储能电池24充电，保证电池能够充足的同时避免充电过度；调压电路22是根据吸烟装置的功能需要将外部充电设备输入的电压调整至4V-24V，具体调整电压可根据需求设定，可将低电压变换为高电压，根据需要也可将高电压变换为低电压，其支持充电电压与系统电压不同，使得充电更便利，同时提供给加热电路26更高的烤制功率，给使用者提供较佳的烤制口感；充电保护电路23，是指针对电路存在一些不稳定因素，而设计用来防止此类不稳定因素影响电路效果的回路，在给储能电池24充电时，当电池电压超过其最大阈值时，过充电控制电路截止电流，停止充电，当储能电池24处于放电状态下，电池电压降至最小阈值时，过放电控制电路截止，停止向负载供电；加热控制电路28用于根据加热电路26的温度通过电子开关25控制加热电路26的输出功率，一般包括该装置中使用的MCU及其外围电路；电子开关25，包括受加热控制电路28控制开通或关断的电子开关管，该电子开关管直接连接至储能电池24，通常采用金属-氧化层-半导体-场效晶体管；加热电路26用于烟叶仓加热；温度采样电路27，该电路用于将加热部件、相邻部件或使用环境的温度反馈至加热控制电路28，温度采样电路27中包括用于将温度信号转换为电信号的温度传感器，温度传感器包括热电偶、热敏电阻、电阻温度检测器（RTD）和IC温度传感这四类，常用的是热电偶或NTC；加热控制电路28、电子开关25、加热电路26以及温度采样电路27组成一个闭环以控制加热输出功率，简单来说就是温度采样电路27如探测到采样温度低于设定温度，则通过加热控制电路28开通电子开关25，使加热电路26工作，加热单元温度升高，温度采样电路27温度同样也升高，如采样温度超过设定温度，则通过加热控制电路28关闭电子开关25，加热电路26关闭，温度采样电路27的采样温度同样也会随之降低，如此循环的一个系统，开通和断开是两个极端状态，一般该反馈控制系统工作于PWM状态下的间歇情况，以实现更精准的烤制功率控制，给使用者提供更佳的烤制口感。
此外，为消除储能电池24两端的电压与加热控制电路28中MCU所需的电压之间的差异，可在加热控制电路28与储能电池24之间增加DC/DC电路，该电路用于将已经调压的电源电压，重新调整至加热控制电路28中MCU需要的电压。

3）同时充电和烤制过程，当外部充电设备通过充电电路21、调压电路22和充电保护电路23为储能电池24充电时，用户可以同时触碰电子开关25开启加热电路26，实现同时充电和烤制，在该过程中，温度采样反馈过程也正常进行。
加热控制电路28一般采用PWM单环反馈控制方式，PWM开关在输入电压变化、内部参数变化、外接负载变化的情况下，控制电路通过被控制信号与基准信号的差值进行闭环反馈，调节主电路开关器件的导通脉冲宽度，使得开关电源的输出电压或电流等被控制信号稳定。 PWM的开关频率一般为恒定，控制取样信号有：输出电压、输入电压、输出电流、输出电感电压、开关器件峰值电流。由这些信号可以构成单环、双环或多环反馈系统，实现稳压、稳流及恒定功率的目的，同时可以实现一些附带的过流保护、均流等功能。
