电池16可以是但不限于磷酸铁锂(LiFePO4)电池。例如，电池16可以是钴酸锂(LiCoO2)电池或钛酸锂电池。电池16可以是可反复充电电池或一次性电池。在本实例中，电池16为一次性电池。
传感器17用于检测用户的抽吸动作并生成对应的电信号，以使得电路15根据该电信号控制电池16和加热组件的操作。传感器17可以采用常见的压力传感器，例如咪头，但不限于此。
电子烟100邻近传感器17的位置处设置有进气孔，在电子烟100被抽吸时，气流通过进气孔进入，流经传感器17、电池16、电路15、加热组件等后，通过吸嘴11流出，图中的虚线箭头大概地示出了该气流路径。
需要说明的是，图1仅示出与本实施例相关的部件。本技术领域的普通技术人员应理解，电子烟100还可包括除图1所示的部件以外的其他通用的部件。
图2是本申请实施例提供的另一电子烟100示意图。与图1所示的电子烟不同的是，液体储存单元12包括相互分隔的第一液体储存单元121和第二液体储存单元122；第一液体储存单元121用于存储第一液体，第二液体储存单元122用于存储第二液体；第一液体传递单元131将第一液体储存单元121的第一液体传递到第一加热元件132，第一加热元件132用于加热第一液体传递单元131传递的第一液体；第二液体传递单元141将第二液体储存单元122的第二液体传递到第二加热元件142，第二加热元件142用于加热第二液体传递单元141传递的第二液体。
其中，所述第一液体的成分和所述第二液体的成分可以相同也可以不相同。在本示例中，所述第一液体的成分和所述第二液体的成分不相同，从而在用户的抽吸过程中，当第一加热元件132和第二加热元件142交替地启动加热时，用户可以享受不同口味的气溶胶，进一步地提升用户的抽吸体验。
图3是本申请实施例提供的电子烟控制方法流程示意图。如图3所示，该方法包括：
步骤S11、在获取到所述电子烟的抽吸指令的情况下，控制所述第一加热组件和所述第二加热组件中的任意一个加热组件启动加热。
具体地，在电子烟100被抽吸时，气流通过进气孔进入流经传感器17时，传感器17可检测到用户的抽吸动作并生成对应的电信号，例如：当用户抽吸时，电子烟100中的气道压力低于外界气流的压力，咪头输出一高电平信号，电路15在获取到高电平信号之后可判定存在抽吸动作，进而控制第一加热元件132和第二加热元件142中的任意一个加热元 件启动加热，生成用户可吸食的气溶胶。
步骤S12、获取所述电子烟的抽吸特征参数。
在本示例中，所述抽吸特征参数选自以下至少之一：
抽吸次数、抽吸时间、抽吸量、抽吸频率、加热组件的阻值、加热组件的阻值变化、加热组件的温度、加热组件的温度变化。
例如，在通过咪头检测到用户的抽吸动作时，可通过计数器对用户的抽吸次数进行计数或者可通过一定时器对用户的抽吸时间进行计时，抽吸时间可以是一次或者多次抽吸动作的持续时间；抽吸量和抽吸频率也可通过抽吸次数和抽吸时间计算得到。
当加热元件采用具有一定电阻温度特性的元件时，加热元件的电阻值随着工作温度的变化会相应发生显著变化。因此，可通过检测加热元件的工作电流和电压，即可计算得到加热元件的阻值；或者，还可以通过设置与加热元件串联的采样电阻，然后根据采样电阻和加热元件的电压分配以及总电压来计算加热元件的阻值。一般地，加热元件的电阻与温度呈正比关系，因此可进一步地确定加热元件的温度及其变化。
步骤S13、基于所述抽吸特征参数，控制所述任意一个加热组件停止加热并控制另一个加热组件启动加热。
具体地，在获取到所述电子烟100的抽吸特征参数之后，即可基于该抽吸特征参数控制所述任意一个加热元件停止加热并控制另一个加热元件启动加热，实现了加热元件之间的一次切换，避免了所述任意一个加热元件由于供油不及时或者不充分导致的糊芯现象，同时所述另一个加热元件对应的液体传递单元有充足的时间将液体储存单元12的液体传递到该加热元件。
如图4所示，步骤S13具体地包括：
步骤S131、将所述抽吸特征参数与预设阈值进行比较；
步骤S132、在所述抽吸特征参数超过所述预设阈值的情况下，控制所述任意一个加热组件停止加热并控制另一个加热组件启动加热。
具体地，可将抽吸次数与预设的抽吸次数进行比较，或者将抽吸时间与预设的抽吸时间进行比较，或者将所述任意一个加热元件的阻值与预设的阻值进行比较，或者将所述任意一个加热元件的温度与预设的温度进行比较，然后根据比较结果控制所述任意一个加热元件停止加热并控制另一个加热元件启动加热，实现了加热元件之间的一次切换。
步骤S14、再次获取所述电子烟的抽吸特征参数。
步骤S15、基于再次获取的抽吸特征参数，控制所述另一个加热组件停止加热并控制所述任意一个加热组件启动加热。
图5是本申请实施例提供的电子烟控制过程示意图。该控制过程以抽吸次数为例进行说明，具体地包括：
步骤S21、在获取到所述电子烟的抽吸指令的情况下，控制第一加热元件132启动加热；
步骤S22、通过传感器17检测用户的抽吸动作，并计算抽吸次数；
步骤S23、若计算的抽吸次数≥预设的抽吸次数，则控制第一加热元件132停止加热并控制第二加热元件142启动加热(步骤S24)；否则继续通过传感器17检测用户的抽吸动作，并计算抽吸次数(步骤S22)；
步骤S25、通过传感器17检测用户的抽吸动作，并重新计算抽吸次数；
步骤S26、若重新计算的抽吸次数≥预设的抽吸次数，则控制第二加热元件142停止加热并控制第一加热元件132启动加热(步骤S27)；否则继续通过传感器17检测用户的抽吸动作，并计算抽吸次数(步骤S25)；
步骤S28、通过传感器17判断用户是否停止抽吸，若用户停止抽吸则控制第一加热元件132停止加热，抽吸结束(步骤S29)；否则继续通 过传感器17检测用户的抽吸动作，并计算抽吸次数(步骤S22)。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但是，本申请可以通过许多不同的形式来实现，并不限于本说明书所描述的实施例，这些实施例不作为对本申请内容的额外限制，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。并且，上述各技术特征继续相互组合，形成未在上面列举的各种实施例，均视为本申请说明书记载的范围；进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
