S300 、当电子烟从充电口插入时，触发靠近充电口设置的触发开关，进入充电模式，在充电模式下，生成充电电流并向电子烟输出充电电流，对插入的电子烟充电。
S301 、当 电子烟 充满电时，进入超低待机模式，在超低待机模式下，停止生成充电电流，使电子烟盒的待机电流小于 10 微安。
本发明实施例提供的电子烟盒及其对电子烟盒进行充电的方法，在有电子烟插入时自动触发进入充电模式，生成并输出充电电流对所插入的电子烟进行充电，并在 电子烟 充满电后，停止生成充电电流，使电子烟盒总的待机电流降低至10 微安以下，不需如现有的电子烟盒一般不断地或间隔地启动查询过程，来查询是否有 电子烟 插入电子烟盒上的充电口，也不需在电子烟充满电后仍继续生成充电电流直至电子烟被拔出，可以明显降低电子烟盒的待机功耗，减少电子烟盒的充电次数，延长电子烟盒内置电池的使用寿命，提升用户体验。
由于本发明的电子烟盒需与电子烟配合使用，在本发明的各种实施例中，根据电子烟的不同，电子烟盒的结构也不同。
例如，若电子烟为硬质材料制成，触发开关 120 可以包括靠近充电口设置的弹性按钮（如图 4 所示的开关 K ）和与该弹性按钮通信相连的信号发生器（如图 4 所示的由第十一电阻 R11 、第十二电阻 R12 、第五电容 C5 、第六电容 C6 、三端可调分流基准源 U3 构成的电路模块），当电子烟插入充电口时，弹性按钮被电子烟挤压，闭合信号发生器电路，从而启动信号发生器生成插入信号。具体地，弹性按钮可以是弹片或弹簧等机械式按钮，当电子烟没有插入充电口时，弹性按钮处于原始状态，在充电口附近凸出。当电子烟插入充电口时，弹性按钮与电子烟接触并被电子烟挤压，处于压缩状态，从而闭合与其相连的信号发生器电路。本领域技术人员应当理解，除了在电子烟插入充电口时生成插入信号以外，触发开关 120 还可以在电子烟拔出充电口时生成拔出信号。如图 4 所示，三端可调分流基准源 U3 为 TL431 ， TL431 的阳极与控制器芯片HT46R01B 的PA7 端口连通，TL431 的阴极经由R12 与一基准电压VDD 连通，TL431 的阴极还与一2.5V 正电压连通，TL431 的参考极也与该2.5V 正电压连通，C6 连接在2.5V 正电压与地之间；弹性按钮K 连接在控制器芯片的PA6 端口与一负电压OUT- 之间，R11 的第一端通过弹性按钮K 与负电压OUT- 连通，R11 的第二端与基准电压VDD 连通，R11 的第二端还经由C5 与地连通。
又例如，若电子烟中的电池杆采用磁铁连接结构，那么触发开关可以包括靠近充电口设置的霍尔开关，当具有磁铁的电子烟插入充电口时，霍尔开关生成插入信号。具体地，当电子烟插入充电口时，其内部磁铁导致霍尔开关的外加磁场发生改变，霍尔开关可以根据霍尔效应的原理检测到其外加磁场的变化，并将利用模拟信号或数字信号将这种变化输出。本领域技术人员应当理解，除了在电子烟插入充电口时生成插入信号以外，触发开关 120 还可以在电子烟拔出充电口时生成拔出信号。
又例如，若电子烟的电池杆连接有充电管理电路，那么充电检测模块 130 可以包括充电电流检测模块，用于检测电子烟充电输出模块 140 向电子烟输出的充电电流，当所检测到的充电电流小于一预设电流阈值时，确定电子烟充满电。其中，预设电流阈值可以是 20 毫安。具体地，若电子烟的电池杆连接有充电管理电路，那么当电子烟充满电后，充电管理电路会控制电子烟的电压基本上保持不变，并使充电电流减小很多以持续对电子杆充电，因此，只要充电检测模块 130 检测到充电电流小于该预设电流阈值时，就可以确定电子烟已充满电了。如图 4 所示，充电电流检测模块 130 可以包括第九电阻 R9 、第十电阻 R10 和第四电容 C4 ， R10 连接在电子烟的电池杆负极与地之间， R9 连接在电池杆负极与控制器芯片 HT46R01B 的 PA5 端口之间， C4 连接在控制器芯片的 PA5 端口与地之间。
又例如，若电子烟的电池杆没有连接充电管理电路，那么充电检测模块 130 可以包括电压检测模块，用于检测电子烟的电压，当所检测到的电压大于一预设电压阈值时，确定电子烟充满电。其中，预设电压阈值可以是 4.2 伏。具体地，若电池杆没有连接充电管理电路，那么即使在电子烟充满电后，只要电子烟盒仍然向电子烟输出充电电流，电子烟的电压仍然会继续上升，因此充电检测模块 130 只需检测到电子烟电压超过一预设电压阈值时，就可以确定电子烟已充满电了。如图 4 所示，电压检测模块可以包括第七电阻 R7 、第八电阻 R8 和第二电容 C2 ，R7 和R8 依次串联在电子烟的电池杆正极与地之间，R7 和R8 的公共节点与控制器芯片HT46R01B 的AN2 端口连通，C2 连接在控制器芯片的AN2 端口与地之间。
如图 4 所示，控制器 110 可以包括由芯片 U1 、第三电容 C3 和第三二极管 D3 构成的电路模块，其中芯片 U1 的型号可以是 HT46R01B 。C3 连接在HT46R01B 的基准电压（VDD ）端口与地之间，D3 的正极连接一基准电压VDD ，D3 的负极连接HT46R01B 的基准电压端口。另外，HT46R01B 的PA4 端口与电子烟充电输出模块140 连通，AN3 端口与2.5V 正电压连通，AN1 端口与电子烟盒内置电池充电模块连通以检测电子烟盒内置电池的电压。
请参见图 2 ，为图 1 所示电子烟盒对插入其中的电子烟充电的工作时序图。如图 2 所示，将触发开关 120 发出的信号--插入信号和拔出信号--用'触发信号'来表示，将电子烟充电输出模块 140 的输出用'充电输出'来表示，其中，插入信号为高电平，拔出信号为低电平。当电子烟插入充电口触发触发开关 120 时，触发开关 120 生成高电平的插入信号，即出现上升沿，该上升沿触发控制器 110 启动电子烟充电输出模块 140 生成并输出充电电流（充电电流在数字电路中表现为输出高电平）对电子烟充电。当充电检测模块 130 检测到电子烟充满电后，控制器 110 控制电子烟充电输出模块 140 停止生成充电电流（无电流或因电流较小而在数字电路中表现为输出低电平），不再对电子烟充电。当电子烟从充电口拔出时，触发开关 120 复原，生成低电平的拔出信号。再次有电子烟插入充电口时，重复上述过程。
虽然图 2 示出了利用脉冲信号进行控制的数字信号控制方法，但本发明并不受限于此，在本发明的其它实施例中，还可以采用本领域技术人员熟知的任意其它方法还进行电路控制。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护之内。
