其中，控制器20还根据至少一个检测值确定下一次点烟过程中变压装置10的目标变压比的实现可以为：控制器20至少一个检测值确定电池40在下一次点烟过程中的参考电压值，以及计算预定电压与参考电压值的比值得到所述下一次点烟过程中变压装置10的目标变压比。
可选的，控制器20还根据至少一个检测值确定电池40在下一次点烟过程中的参考电压值可通过以下几种方式实现：
第一种，获取该至少一个检测值中的最小值得到电池40在下一次点烟过程的参考电压值。
第二种，利用该至少一个检测值中的最小值加上常数得到雾化器下一次点烟过程中的参考电压值。换句话说，电池40的电压在一次点烟过程中被频繁地检测，并且存储至少一个检测值。其中，较小的检测值趋向于通电雾化器的阻值，考虑到电池40电压的波动和短时恢复，利用该至少一个检测值中最小值加上常数得到电池40在下一次点烟过程中的参考电压值。其中，常数通常由系统开发人员设定，例如常数可以为200mV。
本申请以电压检测装置独立于控制器20以及变压装置10来举例说明，电压检测装置包括输出代表实际电池40电压的数值的模拟数字转换器(Analog to Digital Converter，ADC)，ADC与控制器20相连接。在实际实现时，电压检测装置可集成于控制器20中或变压装置10中。
本发明还提供了一种电子烟，该电子烟包括上述实施例所涉及的控制电路和雾化器。
请参考图2，其示出了本发明一个实施例提供的一种电子烟的控制方法的方法流程图。如图2所示，该电子烟的控制可以包括：
步骤210，获取变压装置恒定输出的预定电压，以及获取雾化器的阻值、目标雾化功率。
步骤220，在接收到点烟信号时，根据该预定电压、目标雾化功率以及雾化器的阻值，控制电子控制元件在打开状态、闭合状态之间切换，以使雾化器按照目标雾化功率恒定输出，该电子控制元件串联在该变压装置的电压输出端与该雾化器之间。
可选的，在该点烟信号未中断前，至少检测一次电子烟的电池的电压；根据检测出的至少一个检测值确定下一次点烟过程中变压装置的目标变压比；在所述下一次点烟过程中，控制变压装置按照该目标变压比进行变压，以使变压装置继续按照预定电压恒定输出。
其中，根据检测出的至少一个检测值确定下一次点烟过程中变压装置的目标变压比的实现可以为：根据检测出的至少一个检测值确定电池在下一次点烟过程中的参考电压值，以及根据该参考电压值、该预定电压确定所述下一次点烟过程中变压装置的目标变压比。
可选的，在该点烟信号中断后、接收到新的点烟信号之前，控制变压装置停止变压，或者，根据预定电压、雾化器的目标保温功率控制电子控制元件在打开状态、闭合状态之间切换，以使雾化器按照目标保温功率恒定输出。
综上所述，本发明实施例提供的方法，通过获取变压装置恒定输出的预定电压，以及获取雾化器的阻值、目标雾化功率；在接收到点烟信号时，根据该预定电压、目标雾化功率以及雾化器的阻值，控制电子控制元件在打开状态、闭合状态之间切换，以使雾化器按照目标雾化功率恒定输出，该电子控制元件串联在该变压装置的电压输出端与该雾化器之间；解决了相关技术中电子烟使用过程中电池电压降低导致的雾化器的发热功率下降、影响电子烟的抽吸口感的问题；达到了在抽吸过程中可以以目标雾化功率恒定输出，进而提高电子烟的抽吸口感的效果。
术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或隐含所指示的技术特征的数量。由此，限定的“第一”、“第二”的特征可以明示或隐含地包括一个或者更多个该特征。在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本领域普通技术人员可以理解实现上述实施例的全部或部分步骤可以通过硬件来完成，也可以通过程序来指令相关的硬件完成，所述的程序可以存储于一种计算机可读存储介质中，上述提到的存储介质可以是只读存储器，磁盘或光盘等。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
