具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
本申请实施例提出一种电子烟的控制方法，基于对不同触发来源导致的气流传感器触发信号进行判断，并根据判断结果来控制电子烟的工作。具体，本 申请实施中根据使用中气流传感器触发的原因，分为烟油渗漏触发和正常抽吸触发两种，这两种情形下气流传感器的触发信号波形图参见图1和图2所示，气流传感器能输出以上图1和图2所示的波形是基于其内部的结构实现的，其通常包含有电容式传感部分、以及信号采样输出部分；电容式传感部分当被渗漏的烟油或者抽吸气流引起电容变化；信号采样输出部分按照一定的频次/时间采集电容式传感部分的电容变化，当在采样时间内检测到电容式传感部分存在电容变化时，则输出高电平信号，当在采样时间内没有检测到电容式传感部分的电容变化、以及在采样动作之间的间隔时间均输出低电平信号，从而形成图1和图2所示的高、低电平交替变化的波形图。当然，不同厂家生产的气流传感器的信号采样输出部分的采样频次和时间会略有差别，但应用于电子烟产品触发控制上，通常绝大部分厂家将气流传感器的信号采样输出部分的采样频次和时间间隔均设置在100ms以内。
根据信号图显示的内容比较，图1所示为烟油渗漏至气流传感器上引起的气流传感器触发信号的波形图，气流传感器产生的高、低电平信号交替的变化的频率较高，相邻高电平/低电平信号的时间间隔低于200ms，通常不同气流传感器生产厂家生产的气流传感器低电平的间隔略有区别，大致都处于30～180ms范围；并且信号的波形呈相对较为规则的时间周期性变化，比如图1中以一厂家生产的气流传感器在渗油时被触发的波形信号周期为158.4ms、高电平信号值平均为2.76V、低电平的时长约54.4ms。而图2所示的用户抽吸引起的气流传感器触发信号的波形图，气流传感器产生的高电平的信号持续时间较长，通常根据用户抽吸时的吸气长度时间约为1s～4s，吸气间隔的低电平信号时间也长于烟油渗漏的情形，高、低电平信号交替变化的频率较低；并且抽吸引起的气流传感器触发信号的波形受用户抽吸时呼气和吸气时间长度影响，相对不具有如图1所示波形的周期性。
因此，根据图1和图2体现的不同触发情形下气流传感器的触发信号的区别，本申请一实施例的电子烟的控制方法，包括如下步骤：
S10，检测气流传感器发送的低电平信号的持续时间是否大于预设的阈值；若是，执行步骤S20；若否，则不做响应，并继续检测下一次低电平信号；
S20，检测是否接收到气流传感器发送的高电平信号；若是，则执行步骤S30；若否，则不执行任何动作，继续检测高电平信号；
S30，控制电子烟工作。
以上实施例所体现的控制方法的过程，根据气流传感器产生的低电平信号的持续时间，进而来决定是否响应高电平信号的触发，使电子烟工作；如果低电平的持续时间过短，则可以认为气流传感器是被渗漏的烟油误触发。因而只有在当检测的低电平时间大于一定时长时，才输出控制信号控制电子烟正常工作，从而避免气流传感器在被渗漏的烟油误触发时仍然控制电子烟工作导致干烧的问题。
需要说明的是，以上步骤S10中基于以上图1和图2所示的气流传感器的波形信号，低电平信号的持续时间是由该低电平信号的前一次高电平信号和后一次高电平信号之间的间隔时间计算获得，如图1和图2中所示的高电平信号之间的间隔T0，预设的时间阈值为T1，程序执行过程中根据T1和T0的比较结果。
在更加优选的实施方式中，根据以上图1所示的烟油渗漏引起的气流传感器触发信号中低电平信号的持续时间间隔低于200ms的情形，步骤S20的预设的阈值可以设定为200ms或者高于200ms，则可以基本上覆盖不同生产厂家生产的气流传感器，保证检测的结果准确。当然，进一步在该预设的阈值设定时，使其小于图2中用户吸气间隔时的低电平时间1s～4s，以避免将阈值设置的过大导致正常抽吸时电子烟不工作的情形。
采用以上实施方式进行控制时，每次收到气流传感器表示触发的高电平信号时，需要完成对之前的低电平信号时间进行采样和比较计算，从接收到高电平触发信号直至得出结果控制电子烟工作需要一定的时间，从而导致电子烟开始工作与用户抽吸动作存在相对略长时间的延迟；而由于气流传感器的高低电平信号是交替性的，每次对低电平信号计算导致的延迟时间，如果比抽吸的间隔时间(以上所述最低约1s)长或者相当，那么下一次高电平信号发出时前一次触发后还没有开始正常工作，则影响抽吸体验。
因而基于以上情形，本申请在一优选实施方式中，采用在控制过程中增加一用于标记气流传感器是否正常的状态标志，当接收到气流传感器产生的高电平信号时，通过查看和判断状态标志是否表示正常，若表示正常则响应触发控制电子烟工作，若表示异常则不响应，能缩短对低电平时间的采样和比较计算的时间，消除信号和控制延迟的问题。具体该优选实施方式的控制方法，包括 如下步骤：
S10a，设置一用于标记气流传感器正常状态或异常状态的状态标志；当然，该状态标志的标记内容可以后续根据气流传感器的电平信号检测在正常状态或异常状态的两种状态之间进行更改；为了便于程序的运行，在该步骤S10a设置该状态标志时，本实施例中使其初始状态标记为正常状态；
S20a，检测是否接收到气流传感器的高电平信号；若是，执行步骤S30a；若否，则执行步骤S40a；
S30a，检测状态标志的标记内容是否为正常状态状态；若是，则执行步骤S31a，控制电子烟工作；若否，则不做响应；
S40a，检测气流传感器的低电平信号的持续时间是否大于预设的阈值；若是，则执行步骤S41a，将状态标志的标记内容调整为标记正常状态；若否，则执行步骤S42a，将状态标志的更改为标记异常状态。
采用这一实施方式的步骤进行时，通过状态标志对气流传感器的触发进行标记和区分，每一次当接收到气流传感器的高电平触发信号时，只需要检测当前状态标志所标记的状态是否为正常状态，进而最快速地输出是否响应。而状态标志在每一次低电平信号的时间采样比较后，会根据比较结果进行状态更新，保证结果准确性
进一步，以上状态标志根据控制器和程序设计的常规选择，采用标志寄存器(PSW)存放状态标志运算结果，并且其结果只需要体现两种状态信息；优选采用程序设计中常用的零标志位(ZF)作为状态标志，即当运算结果为零时ZF＝1，否则ZF＝0。用于以上实施方式中时，将“ZF＝0”表示正常状态，而“ZF＝1”表示异常状态，步骤S40的程序设计时根据判断的结构只需要对零标志位进行置位和清零两种操作处理，程序的执行更加简单。
当然，该优选实施方式中，步骤S40a中的用于作为比对的预设的阈值，根据气流传感器被抽吸动作抽吸触发和漏油触发时低电平信号的时间长度不同，将预设的阈值设置为200ms或者高于200ms、并小于用户吸气间隔1s～4s的时长。
以上方法实施中，基于软件的每次运行时必须要能获取到状态标记的确定数据要求，因而状态标志的初始标记内容必须要设置，比如以上ZF＝1或ZF＝0的数据状态必须使其中之一为初始数据状态，进而能被获取和检测，因而在以 上实施例中将ZF＝0的清零状态作为初始设置表示正常状态。
需要说明的是，初始标记内容是正常状态或异常状态在实施中都不影响产品的正常使用。具体在电子烟使用场景情形下：
如果在电子烟产品开机之后立刻抽吸使气流传感器触发，状态标志初始设置标记为正常状态，程序正常运行。在电子烟产品正常存放无漏油下抽吸使气流传感器触发，抽吸之前程序运行通过步骤S20a的判断和步骤S40a也会维持状态标志为标记正常状态，程序运行不会发生误触发。
而如果当漏油导致气流传感器被触发时，则气流传感器第一次产生约100ms高电平信号之后程序以正常状态状态控制电子烟工作运行一次之后，第一次低电平信号过程时由步骤S20a判定进入步骤S40a，将状态更改为异常，后续电子烟均不会在异常触发下继续工作。整体过程中，电子烟仅有第一次约100ms的时间会短时间工作，而后续电子烟均不会被触发工作，直至气流传感器上渗漏的烟油被清理后，电子烟重启开机后程序重新运行。
在另一种初始设置方式下，如果将状态标志的初始标志内容设置为异常，则此种设置下：
如果气流传感器被抽吸动作触发产生高电平信号时，用户抽吸的第一次吸气动作，不会触发电子烟工作；而第一次吸气结束的低电平信号超过200ms，按照步骤S20a和步骤S40a的条件执行将状态标志的标志内容改为正常状态状态，后续正常工作。
如果气流传感器被渗漏的烟油触发产生高电平信号，则程序运行中第一次高电平信号也不会触发电子烟工作。
以上两种状态标志的初始设置方式，优选采用初始设置为正常状态状态，那么电子烟始终能与抽吸的触发动作配合工作，而只有漏油触发的第一次较短的时间约100ms会被触发工作，相比用户体验效果上较初始设置为异常状态的方式更好。
基于以上通过状态标记对气流传感器的触发状态进行标记，并根据收到的气流传感器的信号从而对状态标记所标记的内容进行实时更改，从而后续供控制器在接收到高电平信号时作为参考的立意。以上实施例中通过低电平信号的持续时间来对状态标记所标记的内容进行调整的方式，可以替换为采用具有相 同效果的特征进行。具体，
根据图1和图2所示的信号波形图所示，气流传感器在正常和异常的情形下，发出的信号波形具有明显不同的频率和周期，比如图1中以一厂家生产的气流传感器在渗油时被触发的波形信号周期为158.4ms、低电平的时长约54.4ms；其在单位时间内高电平和/或低电平的频次明显要高于图2所示的正常抽吸时的波形信号。因此，以上步骤S40a的内容可以替换为：
S40b，检测气流传感器的高电平信号的持续时间是否大于预设的阈值；若是，则执行步骤S41a，将状态标志的标记内容调整为标记正常状态；若否，则执行步骤S42a，将状态标志的更改为标记异常状态。
或者S40c，检测气流传感器单位时间内发送的低电平和/或高电平信号的频次是否大于预设的阈值；若是大于预设的阈值，则对应将状态标记调整为标记异常状态；若不是大于预设的阈值，则对应将状态标记调整为标记正常状态。
当然，以上如果以检测单位时间内发送的低电平和/或高电平信号的频次进行标记状态调整时，实施过程中，控制器需要采集这一段时间内的信号，相比仅采样某一个低电平或者高电平的持续时间的方式，在采样时间上更长。可能采样结束之后再计算得出结果，时间上可能不如直接以低电平或者高电平的持续时间调整状态标记更加快捷。
