为了便于理解本发明，下面将参照相关附图对电子烟及其控制方法进行更全面的描述。附图中给出了电子烟及其控制方法的首选实施例。但是，电子烟及其控制方法可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对电子烟及其控制方法的公开内容更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
如图1所示，一实施方式的电子烟10包括电源模块100、发热组件200、功率测量模块300和功率调节模块400。电源模块100可以是锂电池，也可以是其他类型的电源。功率测量模块300分别与发热组件200、功率调节模块400连接，用于测量发热组件200的当前功率并向功率调节模块400输出控制信号。功率调节模块400连接在电源模块100和发热组件200之间，用于根据控制信号调节输出到发热组件200的功率。通过功率测量模块300检测发热组件200的当前功率并向功率调节模块400输出控制信号，功率调节模块400根据控制信号调节输出到发热组件200的功率，从而精确的调节发热组件200的功率，使发热效率稳定，提高电子烟10的烟雾量和口感的稳定性。
功率测量模块300测量发热组件200的当前功率的方式可以是通过功率计直接测量，也可以通过测量电压值和电流值，计算得到当前功率。同时参见图2、图3，在其中一个实施例中，功率测量模块300包括电压检测单元320、电流检测单元340和微处理单元360。电压检测单元320与发热组件200连接，用于检测发热组件200的电压值。在一实施例中，发热组件200为发热丝，电压检测单元320分别与发热丝的两端连接，以检测发热丝的两端的电压值。电流检测单元340与发热组件200连接，用于检测发热组件200的电流值。微处理单元360分别与电压检测单元320和电流检测单元340连接，用于获取电压值和电流值，并根据电压值和电流值输出控制信号。
一般情况下，电源模块100的输出电压随电量减低而变化、发热组件200的电阻值随着温度的变化而变化，亦或是更换了不同阻值的发热组件200，均会对发热组件200的发热效率造成影响。本实施例的电子烟10通过电压检测单元320和电流检测单元340检测发热组件200的电压值和电流值，可以准确的确定发热组件200的功率。无论电源模块100的输出电压发生变化，还是发热组件200的电阻值发生变化，根据电压值和电流值计算出的发热组件200的当前功率都是准确的，从而能够准确的调节输出到发热组件200的功率，保证发热组件200的发热效率稳定，提高电子烟10的烟雾量和口感的稳定性。
在其中一个实施例中，微处理单元360预设有目标功率，微处理单元360用于根据电压值和电流值计算获得发热组件200的当前功率，若当前功率与目标功率不同，则输出控制信号。进一步的，在一实施例中，电子烟10还可以包括输入模块500，输入模块500可以与功率测量模块300的微处理单元360连接，用于设定目标功率。一般出厂时，微处理单元360会预设目标功率，交给用户使用后，用户可以通过输入模块500重新设定目标功率，进而用户可以根据需要调节电子烟10的烟雾量和口感。当然，出厂时也可以不进行预设，用户第一次使用时通过输入模块500进行第一次预设。
再参见图2、图3，在其中一个实施例中，功率调节模块400包括PWM（Pulse-Width Modulation，脉冲宽度调制）控制单元420和开关单元440。PWM控制单元420与功率测量模块300连接，具体的，PWM控制单元420可以与微处理单元360连接，用于接收控制信号，根据控制信号调整脉冲信号的占空比，并输出脉冲信号。开关单元440连接于电源模块100和发热组件200之间，且开关单元440与PWM控制单元420连接，用于接收脉冲信号，并根据脉冲信号控制发热组件200通电或断电。在一实施例中，开关单元440为MOSFET（Metal-Oxide-Semiconductor Field-Effect Transistor，金属-氧化物半导体场效应晶体管）开关。
如图4所示，一实施方式的电子烟10的控制方法，用于控制图1至图3所示的电子烟10，以保证电子烟10的发热组件200的发热效率稳定，其包括如下步骤：
S100，功率测量模块300测量发热组件200的当前功率并向功率调节模块400输出控制信号。功率测量模块300测量发热组件200的当前功率的方式可以是通过功率计直接测量，也可以通过测量电压值和电流值，计算得到当前功率。参见图5，在其中一个实施例中，步骤S100可以包括如下步骤：
S120，检测发热组件200的电压值和电流值，根据电压值和电流值计算获得发热组件200的当前功率。在一实施例中，步骤S120中可以间隔预设时间持续检测发热组件200的电压值和电流值，不断的对发热组件200进行发热效率的调整。也可以在后续步骤中设置返回执行步骤S120的步骤。
S140，判断当前功率是否符合预设条件。若不符合预设条件，则执行步骤S160。在一实施例中，预设条件可以是当前功率与目标功率相同，若当前功率与预设的目标功率不同则执行S160。本实施例的判断方式简单，微处理单元360可以快速运行，且微处理单元360耗电低。在另一实施例中，预设条件可以是当前功率与目标功率的差值小于等于预设的容差。容差一般小于等于目标功率的10%。比如容差设置为目标功率的5%，若当前功率与目标功率的差值大于目标功率的5%，则执行S160。
在其中一个实施例中，在步骤S120之前包括设定目标功率的步骤（S110）。设定目标功率可以出厂时直接在微处理单元360上设定，也可以通过输入模块500设定。一般出厂时，微处理单元360会预设目标功率，交用户使用后，用户可以通过输入模块500重新设定目标功率，进而用户可以根据需要调节电子烟10的烟雾量和口感。当然，出厂时也可以不进行预设，用户第一次使用时通过输入模块500进行第一次预设。
在步骤S120中为间隔预设时间持续检测发热组件200的电压值和电流值的实施例中，若步骤S140判断为符合预设条件，本次控制流程可以直接结束。在其他实施例中，若符合预设条件，则返回执行S120，以实现不断的对发热组件200进行发热效率的调整。
S160，输出控制信号。本实施例中，通过电压检测单元320和电流检测单元340检测发热组件200的电压值和电流值，可以准确的确定发热组件200的功率。无论电源模块100的输出电压发生变化，还是发热组件200的电阻值发生变化，根据电压值和电流值计算出的发热组件200的当前功率都是准确的，从而能够准确的调节输出到发热组件200的功率，保证发热组件200的发热效率稳定，提高电子烟10的烟雾量和口感的稳定性。
S200，功率调节模块400根据控制信号调节输出到发热组件200的功率。同时参见图6，在其中一个实施例中，步骤S200可以包括如下步骤：
S220，接收控制信号，根据控制信号调整脉冲信号的占空比，并输出脉冲信号。
S240，接收脉冲信号，并根据脉冲信号控制发热组件200通电或断电。从而控制发热组件200的发热效率。
在一实施例中，在步骤S120中为间隔预设时间持续检测发热组件200的电压值和电流值的实施例中，步骤S200结束后，本次控制流程可以直接结束。在其他实施例中，步骤S200结束后，返回执行S120。即，若当前功率不符合预设条件，则在步骤S160之后，还包括返回执行步骤S120的步骤，以实现不断的对发热组件200进行发热效率的调整。
上述实施例中的电子烟10的控制方法，通过功率测量模块300检测发热组件200的当前功率并向功率调节模块400输出控制信号，功率调节模块400根据控制信号调节输出到发热组件200的功率，从而精确的调节发热组件200的功率，使发热效率稳定，提高电子烟10的烟雾量和口感的稳定性。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
