技术领域
本申请涉及电子烟技术领域，尤其涉及一种童锁控制方法及童锁控制电路、装置、电子烟。
背景技术
电子烟是一种模拟香烟的电子设备，其通过模拟真实香烟的口感和烟雾，从而取代了传统的香烟，不仅节省了消费者的开支，还降低了“二手烟”带来的危害。
目前电子烟在日常生活中比较常见，儿童很容易接触到，部分电子烟都没有童锁功能，又由于儿童的好奇心和模仿，极容易造成儿童误吸食电子烟。因此，出于安全考虑，电子烟非常有必要具有防止儿童误吸误触的童锁功能。目前，市面上电子烟的童锁功能一般使用蓝牙、WIFI、NFC、指纹、触摸按键、机械按键等方式实现儿童防护，童锁功能一般包括加锁功能和解锁功能，一般加锁功能、解锁功能实现的方式是一样的，均是通过使用蓝牙、WIFI、NFC、指纹、触摸按键、机械按键等方式实现，但是，在这些实现方式中，蓝牙、WIFI、NFC、指纹等方式会大幅增加硬件成本，触摸按键、机械按键等方式会额外增加结构设计的复杂性，并对电子烟的外观造成一定的影响。
最近市面上还出现了一种电子烟，实现童锁功能不需要增加硬件成本，具体方案为预设时间内电子烟被抽吸阈值数量，例如2秒内电子烟被抽吸3次，触发电子烟进入锁定状态，实现加锁功能，进入锁定状态后可以防止儿童误吸食电子烟。虽然这样设置可以提升电子烟的安全性，然而，当用户正常抽吸电子烟时，如果抽吸比较快，用户正常抽吸时有可能误触发电子烟进入锁定状态，进入锁定状态后用户再抽吸电子烟不会雾化烟油，需要由锁定状态变为解锁状态后才能恢复正常使用，这给部分用户的使用造成极大不便。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本文中提及“实施例”或“实施方式”意味着，结合实施例或实施方式描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
第一实施例
本申请实施例提供一种电子烟，请结合参见图1和图6，电子烟包括电池110、童锁控制电路200、发热元件130、气流传感器140、功率MOS管M等，童锁控制电路200包括状态检测单元150。童锁控制电路200分别与电池110、气流传感器140、功率MOS管M等电连接。在本实施例中，电池110例如为锂电池、镍镉电池、镍氢电池等可充电电池，电池110也可以为不可充电电池；状态检测单元150与气流传感器140电连接，状态检测单元150用于判断电子烟是否被抽吸和/或被吹气，并输出对应信号，状态检测单元150的一个具体实现方式可参见本领域的在先申请，或者为本领域技术人员知晓的其他常规的状态检测单元。在本实施例中气流传感器140为电容式气流传感器，例如为电容式MEMS传感器或电容式咪头等，气流传感器140位于电子烟的气流通道内，气流传感器140包括电容，状态检测单元150通过电容的电容值等的变化判断电子烟是否处于抽吸状态、吹气状态、未吸吹状态(对应用户未使用时的状态)。童锁控制电路200与功率MOS管M的控制端电连接，童锁控制电路200用于控制功率MOS管M是否导通，功率MOS管M经由雾化端AT与发热元件130串联形成串联支路，串联支路的一端经由电源供电端BAT与电池110的正极电连接，串联支路的另一端经由电源接地端GND与电池110的负极电连接。在本实施例中以功率MOS管M为PMOS管为例进行说明，当然，功率MOS管M也可以为NMOS管。在本实施例中，功率MOS管M、童锁控制电路200可以位于同一个芯片，该芯片一般称为系统控制芯片。但本申请不限于此，在本申请的其他实施例中，功率MOS管M、童锁控制电路200可以位于不同的芯片上。在本实施例中，发热元件130例如为发热丝、加热丝、包含发热丝或者加热丝的陶瓷座、或者其他常规的发热元件。在本实施例中，当童锁控制电路200输出低电平控制功率MOS管M导通时发热元件130加热以使烟油雾化，当童锁控制电路200输出高电平控制 功率MOS管M断开截止时发热元件130停止加热。
在本实施例中，状态检测单元150与气流传感器140电连接，以用于判断电子烟是否被抽吸或者被吹气或者处于未吹气也未抽吸的状态(未吸吹状态)，当用户抽吸电子烟或者向电子烟吹气时，气流传感器140的两个电容电极片之间气压会改变，导致两个电极片之间的距离会随之改变，进而引起气流传感器140的电容值改变，状态检测单元150将电容值改变转换为计数值改变，通过将计数值与预设的数值范围进行比较，状态检测单元150就可以判断电子烟是否被抽吸处于抽吸状态、被吹气处于吹气状态或者未吸吹状态。
为了区分正常抽吸和触发进入锁定状态的抽吸，以降低正常抽吸时被误触发进入锁定状态的概率，本申请的发明人经过大量实验后提出以下方案：对电子烟的抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，气压较小(用户抽吸的吸力较小)的抽吸状态对应用户正常的抽吸，气压更小(用户抽吸的吸力较大)的抽吸状态对应用户想要进入锁定状态的抽吸或者用户偶然的重吸，不管是处于气压较小的抽吸状态，还是处于气压更小的抽吸状态，电子烟均会判断为抽吸状态，本申请通过第一计数信息是否位于第二预设数值范围内判断是否为气压更小的抽吸状态。
具体而言，第一计数信息表征电子烟气流通道内的气压状况，气压状况例如为气压大小、气压的变化状况等，第一计数信息与气流通道内的气压状况呈对应关系，本实施例设计当第一计数信息位于第二预设数值范围内时代表此时处于气压更小的抽吸状态，当第一计数信息位于第二预设数值范围之外且位于第一预设数值范围之内时代表气压较小的抽吸状态，其中，第二预设数值范围位于第一预设数值范围内，也即只要第一计数信息位于第二预设数值范围内，第一计数信息必然位于第一预设数值范围内，表示此时电子烟处于抽吸状态且是重吸，当第一计数信息位于第一预设数值范围内时，第一计数信息可能位于第二预设数值范围内(重吸)，也可能不位于第二预设数值范围内(正常抽吸)。
在本实施例中，第一计数信息包括在第一计数时长的振荡周期数、在第一计数时长的振荡周期数与基准振荡周期数的比值、在第一计数时长的振荡周期数相对基准振荡周期数的差值或者在第一计数时长内振荡周期数相对基准振荡周期数的差值与基准振荡周期数的比值等。在本实施例中，第一计数时长是预设的，电子烟可以采集该时长电子烟的振荡器的振荡周期数，振荡器的振荡周期随气流传感器140的电容变化而变化，当第一计数时长为1s时，此时在第一计数时长的振荡周期数即为频率。当电子烟未被抽吸也未被吹气时，也即电子烟处于未吸吹状态时，此时电容的电极片未变形，此时预设计数时长内计数的振荡周期数即为基准振荡周期数，该预设计数时长可以与第一计数时长相等，也可以不相等，较佳为相等，此时基准振荡周期数是采集获得；另外，基准振荡周期数也可以预设。当用户轻吸导致气压较小时，气流传感器140的电容相对未吸吹状态时较大，振荡器的振荡周期会较长，从而第一计数时长内计数的数值会较小，也即此时第一计数时长的振荡周期数会较小，此时第一计数时长的振荡周期数与基准振荡周期数的比值会较小，第一计数时长的振荡周期数相对基准振荡周期的差值会较大，第一计数时长内振荡周期数相对基准振荡周期数的差值与基准振荡周期数的比值会较大；当用户重吸导致气压更小时，气流传感器140的电容相对未吸吹状态时更大，振荡器的振荡周期会更长，从而第一计数时长内计数的数值会更小，也即第一计数时长的振荡周期数会更小，此时第一计数时长的振荡周期数与基准振荡周期数的比值会更小，第一计数时长的振荡周期数相对基准振荡周期的差值会更大，第一计数时长内振荡周期数相对基准振荡周期数的差值与基准振荡周期数的比值会更大。当用户吹气导致气压变大时，气流传感器140的电容的两个电极片之间的距离相对未吸吹状态时的距离会增大，气流传感器140的电容会较小，振荡器的振荡周期会较小。
当第一计数信息为在第一计数时长的振荡周期数时，此时第二预设数值范围为振荡周期数范围。当气流通道内气压更小时气流传感器140的电容变形更大，电容的两个电极片之间的距离更小，从而其电容值会更大，从而第一计数时长的振荡周期数会更小；当气流通道内气压较小时气流传感器140的电容变形较大，电容的两个电极片之间的距离较小，从而其电容值会较大，从而第一计数时长的振荡周期数会较小，因而第一计数信息与气流通道内的气 压呈比例关系。由于本申请设计成用户重吸才可能进入童锁锁定状态，从而第二预设数值范围的上限值要小于第一预设数值范围的上限值，第二预设数值范围的下限值大于或等于第一预设数值范围的下限值，例如第二预设数值范围为(a，A]，例如A为950，第一预设数值范围(b，B],例如B为970，例如基准振荡周期数为1000，其中，A小于B，a大于或等于b，A、a、B、b为正整数。另外，在本申请的其他实施例中，第二预设数值范围的下限值不设限，也即当第一计数信息小于A即落入第二预设数值范围内。另外，当第一计数信息为在第一计数时长的振荡周期数与基准振荡周期数的比值时，此时第二预设数值范围为比值范围，其原理与前面描述的第一计数信息为在第一计数时长的振荡周期数的方案类似，在此不再赘述，此比值较佳小于或等于0.95，例如为0.9、0.8、0.7等。
当第一计数信息为在第一计数时长的振荡周期数相对基准振荡周期的差值时，此时第二预设数值范围为差值范围。当气流通道内气压更小时气流传感器140的电容变形更大，电容的两个电极片之间的距离更小，从而其电容值会更大，从而差值会更大，当气流通道内气压较小时气流传感器140的电容变形较大，电容的两个电极片之间的距离较小，从而其电容值会较大，从而差值会较大，因而第一计数信息与气流通道内的气压呈比例关系。此时第二预设数值范围的下限值大于第一预设数值范围的下限值，第二预设数值范围的上限值小于或等于第一预设数值范围的上限值，例如第二预设数值范围为[M,m)，例如M为50，第一预设数值范围[N,n),例如N为30，其中，M大于N，m小于或等于n，M、m、N、n为正整数。另外，在本申请的其他实施例中，第二预设数值范围的上限值不设限，也即只要第一计数信息大于或等于M即落入第二预设数值范围内。另外，当第一计数信息为在第一计数时长内振荡周期数相对基准振荡周期数的差值与基准振荡周期数的比值时，此时第二预设数值范围为比值范围，其原理与前面描述的第一计数信息为在第一计数时长的振荡周期数相对基准振荡周期的差值的方案类似，在此不再赘述，此比值较佳大于或等于0.05，例如为0.1、0.2、0.3等。
进一步的，当电子烟处于抽吸状态时，为了判断第一计数信息是否位于第二预设数值范围内，本实施例童锁控制电路200还包括第二计数判断单元211，第二计数判断单元211与状态检测单元150连接，状态检测单元150本身就知道第一计数信息，从而状态检测单元150输出第一计数信息给第二计数判断单元211，第二计数判断单元211用于接收第一计数信息并判断第一计数信息是否位于第二预设数值范围内，进而可以区分用户是正常抽吸还是进入锁定状态的抽吸，经过这样区分，可以降低用户正常抽吸时误判断进入童锁锁定状态的概率。
请结合参见图1、图2和图6，本申请实施例提供一种电子烟的童锁控制方法，包括以下步骤：
S11：接收第一计数信息；
其中，童锁控制电路200包括第二计数判断单元211，第二计数判断单元211与状态检测单元150电连接，状态检测单元150产生第一计数信息，并输出第一计数信息，第二计数判断单元211接收第一计数信息。
在本实施例中，状态检测单元150本身可以识别电子烟是否处于抽吸状态或者吹气状态，当用户抽吸电子烟时，状态检测单元150通过气流传感器140识别电子烟处于抽吸状态，此时状态检测单元150判断第一计数信息位于第一预设数值范围内，状态检测单元150输出抽吸信号，当用户吹气时，状态检测单元150通过气流传感器140识别电子烟处于吹气状态，此时状态检测单元150输出吹气信号，当电子烟既不被抽吸，也不被吹气时，此时状态检测单元150识别电子烟处于未吸吹状态，状态检测单元150输出未吸吹信号。童锁控制电路200接收状态检测单元150的输出信号，从而获取电子烟的状态。当状态检测单元150由输出未吸吹信号转为输出抽吸信号或者吹气信号时，童锁控制电路200获取电子烟由未吸吹状态转为抽吸状态或者吹气状态。在本实施例中，未抽吸状态包括未吸吹状态、吹气状态。
S12:判断第一计数信息是否位于第二预设数值范围内，其中，所述第二预设数值范围位于第一预设数值范围内，所述第一预设数值范围用于判断电子烟是否处于抽吸状态；
S13：若判断结果为是，则触发进行第二计时并触发进行第二计数；
其中，第二计数判断单元211在接收到第二计数信息后，第二计数判断单元211判断第 一计数信息是否位于第二预设数值范围内，第二预设数值范围为预先计算获得，或者预先存储在第二计数判断单元211中。其中，童锁控制电路200包括第二计时单元216和第二计数单元215，第二计时单元216与第二计数判断单元211电连接，第二计数单元215与第二计数判断单元211电连接，若第二计数判断单元211的判断结果为是，则第二计数判断单元211输出计数有效信号，第二计时单元216被触发开始计时，第二计时单元216从0开始计时，第二计数单元215被触发开始计数，并将此次也进行计数，也即此时第二计数单元215的计数为1；若第二计数判断单元211的判断结果为否，则第二计数判断单元211输出计数无效信号，第二计时单元216维持原先的状态，第二计数单元215维持原先的状态。在本实施例中，当第二计时单元216被触发开始计时后，第二计时单元216会一直在计时，直到第二计时单元216被复位置零，此后第二计时单元216停止计时。
当第二计时单元216被触发计时、第二计数单元215被触发计数后，当第二计数判断单元211又接收到第二计数信息，并又一次判断第一计数信息位于第二预设数值范围内，也即又输出计数有效信号，则第二计数单元215的第二计数加1，此时第二计数为2，同时，第二计时单元216在持续进行第二计时。
S14：判断在第二预设时长内第二计数是否大于或等于第二预设数量，其中，第二预设数量大于或等于2；
其中，童锁控制电路200还包括第二计时计数判断单元217，第二计时计数判断单元217分别与第二计数单元215、第二计时单元216连接，当第二计时计数判断单元217判断第二计时单元216的计时时长在第二预设时长内，且第二计数单元215的第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号。在本实施例中，第二预设时长一般小于或等于5s，第二预设时长例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第二预设数量为大于或等于2的整数，例如为2、3、4、5、6等，较佳为3，第二预设数量一般小于或等于6次，方便用户操作。例如，第二预设时长为2秒，第二预设数量为3，则在2秒内第二计数大于或等于3，第二计时计数判断单元217输出童锁锁定信号。
在本实施例中，第二计时计数判断单元217与第二计时单元216、第二计数单元215实时电连接，当第二计时计数判断单元217获取第二计数到达第二预设数量且第二计时单元216未到达第二预设时长时，第二计时计数判断单元217输出童锁锁定信号，或者第二计时计数判断单元217等第二计时单元216计时时长到达第二预设时长时才输出童锁锁定信号。在本申请的其他实施例中，第二计时计数判断单元217与第二计时单元216、第二计数单元215连接，当第二计时单元216到达第二预设时长时第二计时单元216输出信号给第二计时计数判断单元217，第二计时计数判断单元217获取此时第二计数单元215的第二计数，然后判断第二计数是否大于或等于第二预设数量，若第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号，若第二计数小于第二预设数量，则第二计时计数判断单元217维持原来的信号输出。
S15：若判断结果为是，则控制电子烟进入锁定状态，在锁定状态所述功率MOS管M保持断开截止。
其中，童锁控制电路200还包括童锁控制单元240，童锁控制单元240与第二计时计数判断单元217电连接。若第二计时计数判断单元217的判断结果为是，也即在第二预设时长内第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号给童锁控制单元240，童锁控制单元240控制电子烟进入锁定状态，在锁定状态功率MOS管M保持断开，在本实施例中童锁控制单元240持续输出高电平信号给功率MOS管M，功率MOS管M保持截止。在本实施例中，童锁控制单元240包括触发器和开关控制单元，触发器用于对童锁锁定信号、后续的童锁解锁信号进行保持，触发器例如为SR触发器等，开关控制单元分别与触发器、状态检测单元150电连接，开关控制单元例如为与门、与非门、或门、或非门等，例如，开关控制单元包括与非门，与非门的两个输入端分别与触发器的输出端、状态检测单元150的一个输出端连接，童锁锁定信号使触发器的输出保持为低电平，从而经过 与非门后保持为高电平(此时状态检测单元150输出抽吸信号，抽吸信号例如为高电平)，功率MOS管M保持截止；童锁解锁信号使触发器的输出保持为高电平，从而与非门的输出受状态检测单元150的输出影响，当状态检测单元150判断用户抽吸电子烟时，状态检测单元150输出抽吸信号给与非门，抽吸信号为高电平，此时开关控制单元控制功率MOS管M持续导通或者间断导通(例如PWM、PFM控制方式)。若第二计时计数判断单元217的判断结果为否，也即在第二预设时长内第二计数小于第二预设数量，则维持电子烟原先的童锁状态，且第二计数置0，第二计时复位置零。
在本实施例中，电子烟的状态分为锁定状态和解锁状态，其中，锁定状态即对应童锁保护功能，当电子烟处于锁定状态时用户抽吸电子烟，童锁控制单元240继续控制功率MOS管M保持断开截止，从而发热元件130不会加热，进而烟油不会雾化以供用户抽吸，也即即使用户抽吸电子烟也不会出现烟雾。解锁状态对应解除童锁保护功能，此时当用户抽吸电子烟时，童锁控制单元240控制功率MOS管M持续导通或者间断导通，间断导通是指童锁控制单元240通过PWM方式、PFM方式输出方波信号，通过调整方波信号的占空比以用于控制输出功率、输出电压。
在本实施例中，通过接收第一计数信息；判断第一计数信息是否位于第二预设数值范围内，其中，所述第二预设数值范围位于第一预设数值范围内，所述第一预设数值范围用于判断电子烟是否处于抽吸状态，若判断结果为是，则触发进行第二计时并触发进行第二计数；判断在第二预设时长内第二计数是否大于或等于第二预设数量，若判断结果为是，则控制电子烟进入锁定状态。本申请实施例通过第一计数信息、第二预设数值范围对抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，将第一计数信息位于第二预设数值范围的抽吸次数分辨为气压更小的抽吸状态，并进行第二计数，并且在第二预设时长内第二计数大于或等于第二预设数量才使电子烟进入锁定状态，通过这样设置，电子烟可以进一步分辨用户是正常抽吸电子烟，还是想要通过抽吸电子烟触发烟进入锁定状态，电子烟不容易混淆两者，可以降低用户正常抽吸电子烟时被误触发进入锁定状态的几率，可以减少用户的使用困扰。而且，通过在第二预设时长内第二计数大于或等于第二预设数量，可以实现电子烟进入锁定状态，本实施例的电子烟在锁定保护后，可以防止儿童拿起电子烟模仿成人抽吸动作导致电子烟产品开始雾化工作，提升电子烟的使用安全性。而且，本实施例利用现有的状态检测单元150、气流传感器140就可以得到第一计数信息，不需要对电子烟进行大改，不需要增加硬件成本或者增加的硬件成本很小，从而缩减了电子烟进行锁定保护的硬件成本，解决现有技术中电子烟锁定成本较高的技术问题。
在本实施例中，童锁控制方法还包括：再次获取第一计数信息位于第二预设数值范围内的信息，第二计数加1。
具体而言，在第二计数单元215触发第二计数和第二计时单元216触发第二计时后，第二计时单元216和第二计数单元215未停止工作，当电子烟转为未抽吸状态，其后，当用户再次抽吸电子烟，再次实时获取第一计数信息，若第二计数单元215再次获取第一计数信息位于第二预设数值范围内的信息，也即第二计数单元215又收到计数有效信号，则第二计数单元215在原来第二计数的基础上加1，例如原来第二计数单元215的计数值为1，再次获取第一计数信息位于第二预设数值范围内的信息，则第二计数单元215的第二计数加1，也即第二计数变为2；若此次第二计数单元215没有获取第一计数信息位于第二预设数值范围内的信息，也即第二计数单元215没有收到计数有效信号，则第二计数保持不变。
在本实施例中，童锁控制方法还包括：若第二计时达到第二预设时长，则第二计数置零，且第二计时复位置零。
其中，不论第二计时计数判断单元217的判断结果为是还是不为是，只要第二计时单元216的计时时长达到第二预设时长，则第二计时单元216复位置零，同时第二计时单元216发送信号给第二计数单元215，第二计数单元215进行置零，也即此时第二计时单元216停止计时，计时时长置零，第二计时单元216、第二计数单元215恢复初始状态，方便后面信号的检测。在本实施例中，第二计时计数判断单元217在第二计时单元216、第二计数单元 215复位置零前已完成判断。
在本实施例中，童锁控制方法还包括：若第二计时小于第二预设时长且第二计数达到第二预设数量，则第二计数置零，且第二计时复位置零。
其中，若第二计时计数判断单元217获取第二计数达到第二预设数量，且第二计时单元216计时时长小于第二预设时长，则第二计时计数判断单元217输出信号给第二计时单元216、第二计数单元215，第二计时单元216进行复位置零，第二计数单元215置零，该信号可以与童锁锁定信号一样，也可以是不同的信号。
请参见图6，在本实施例中，步骤接收第一计数信息具体包括：
接收状态检测单元150输出的第一计数信息。
其中，状态检测单元150本身可以得到第一计数信息，第二计数判断单元211通过状态检测单元150接收第一计数信息。本实施例充分利用现有电子烟中的气流传感器140、状态检测单元150，只需要增设第二计数判断单元211，第二计数判断单元211所要实现的功能既可以通过软体实现，也可以通过硬件实现，也可以通过软体和硬件结合实现，从而不需要增加新的硬件或者增加新的硬件较少，可以实现不增加成本或者增加少量成本就可以极大的降低电子烟误进入锁定状态的问题，提升了用户的使用便利性。
在应用上述的方案进行实际测试过程中发明人发现：由于空气中气流的扰动，可能会导致处于抽吸状态时瞬间的气压下降，导致第一计数信息到达第二预设数值范围，这个瞬间的气压下降持续时间很短，一般偶尔的一次，造成第二计数单元215误计数，可能误触发电子烟进入锁定状态，给用户的使用造成困扰。为了解决该问题，请结合参阅图3和图6，步骤触发进行第二计数具体包括：
S131:触发进行第三计时并触发进行第三计数；
其中，童锁控制电路200还包括第三计时单元212和第三计数单元213，第三计时单元212、第三计数单元213均与第二计数判断单元211连接，当第三计时单元212、第三计数单元213获取第一计数信息位于第二预设数值范围内时，也即第三计时单元212接收到计数有效信号时，第三计时单元212开始第三计时，第三计时单元212一直计时，直到进行复位置零，此后第三计时单元212停止计时；第三计数单元213接收到计数有效信号时，第三计数单元213开始第三计数，且此次也进行第三计数，此时第三计数为1。
S132:判断在第三预设时长内第三计数是否大于或等于第三预设数量；
其中，童锁控制电路200还包括第三计时计数判断单元214，第三计时计数判断单元214分别与第三计数单元213、第三计时单元212连接，当第三计时计数判断单元214判断第三计时单元212的计时时长在第三预设时长内，且第三计数单元213的第三计数大于或等于第三预设数量，则第三计时计数判断单元214输出第一计数信号。在本实施例中，第三预设时长一般为30ms-150ms，第三预设时长例如为30ms、40ms、50ms、60ms、70ms、80ms、90ms、100ms、110ms、120ms、130ms、140ms、150ms等，较佳为60ms-100ms。在本实施例中，第三预设数量为大于或等于2的整数，例如为2、3等。在本实施例中，第三预设数量大于或等于2，例如为2、3、4、5、6等。
在本实施例中，第三计时计数判断单元214与第三计时单元212、第三计数单元213实时电连接，当第三计时计数判断单元214获取第三计数到达第三预设数量且第三计时未到达第三预设时长时，第三计时计数判断单元214输出第一计数信号，或者第三计时计数判断单元214等第三计时到达第三预设时长时才输出第一计数信号。在本申请的其他实施例中，第三计时计数判断单元214与第三计时单元212、第三计数单元213连接，当第三计时单元212到达第三预设时长时第三计时单元212输出信号给第三计时计数判断单元214，第三计时计数判断单元214获取此时第三计数单元213的第三计数，然后判断第三计数是否大于或等于第三预设数量，若第三计数大于或等于第三预设数量，则第三计时计数判断单元214输出第一计数信号，若第三计数小于第三预设数量，则第三计时复位置零，第三计数置零。
S133:若判断结果为是，则触发进行第二计数。
其中，第三计时计数判断单元214与第二计时单元216、第二计数单元215连接。若第 三计时计数判断单元214的判断结果为是，则第二计时单元216接收到第一计数信号，第二计时单元216被触发开始计时，第二计时从0开始计时；第二计数单元215接收到第一计数信号，第二计数单元215被触发开始计数，此时第二计数单元215对本次也进行计数，也即此时第二计数为1。
在本实施例中，当此前第二计数单元215没有被触发开始计数，第二计时单元216没有被触发开始计时，若第三计时计数判断单元214的判断结果为否，也即第三计时计数判断单元214不输出第一计数信号，第二计数单元215维持原来不进行计数，第二计时单元216维持原来不进行计时；当此前第二计数单元215已被触发开始计数(也即第二计数至少为1)，第二计时单元216已被触发计时，若第三计时计数判断单元214的判断结果为否，则第二计数维持原来的计数，第二计数不增加，第二计时继续计时。
在本实施例中，当空气气流串扰导致电子烟气流通道内气压短时间变化时，由于气压降低的时长很短，从而不会符合在第三预设时长内第三计数大于或等于第三预设数量的条件，从而第二计数不会变化，从而不会将空气气流串扰误判为用户想要进入童锁保护的情况，可以防止电子烟误进入锁定状态，可以防止对用户的使用造成困扰，本实施例可以避免这种情况发生，提升了用户的使用体验。
在本实施例中，在整个第三预设时长电子烟处于抽吸状态，在第三预设时长的部分时长或者整个时长均属于重吸，则第二计时单元216进行计数。
为了判断电子烟是否处于抽吸状态，在本实施例中，童锁控制方法还包括:
接收第一计数信息并判断第一计数信息是否位于第一预设数值范围内；
若判断结果为是，则输出电子烟由未抽吸状态转为抽吸状态的信息。
其中，状态检测单元150包括第一计数生成单元、第一计数判断单元，第一计数生成单元分别与第一计数判断单元、第二计数判断单元211连接，第一计数生成单元生成第一计数信息后，第一计数判断单元接收第一计数信息，第一计数判断单元判断第一计数信息是否位于第一预设数值范围内，若判断结果为是，则第一计数判断单元输出电子烟由未抽吸状态转为抽吸状态的信息，也即输出抽吸信号，若判断结果为否，则第一计数判断单元维持原来的信号输出，例如输出未吸吹信号、吹气信号。进一步的，还可以要求连续多次判断为是，才输出抽吸信号，这样有利于降低气流串扰误触发的几率。在本实施例中，第一计数判断单元、第二计数判断单元211可以为同一判断单元，也可以为不同的判断单元。
在本实施例中，为了降低电子烟处于未抽吸状态时的功耗，步骤接收第一计数信息具体包括：
获取电子烟由未抽吸状态转为抽吸状态的信息；
触发接收第一计数信息。
其中，第二计数判断单元211与状态检测单元150连接，第二计数判断单元211在未收到抽吸信号前不工作，当第二计数判断单元211在接收到抽吸信号后，第二计数判断单元211被触发开始工作，此时第二计数判断单元211接收第一计数信息。这样设置，有利于降低电子烟的功耗。
另外，在本实施例中，请结合参阅图4和图6，在步骤触发进行第二计数之后还包括：
S161:获取电子烟由抽吸状态进入未抽吸状态的信息；
S162:触发第五计时且对第二计数进行锁定；
S163:判断第五计时是否大于或等于第五预设时长；
S164:若判断结果为是，则解除对第二计数的锁定。
本实施例还对两次抽吸状态(包含两次重吸)之间的间隔时长进行规定，防止抽吸状态时气流抖动、串扰等而导致误第二计数。具体而言，在本实施例中，童锁控制电路200包括第五计时单元221和第五时长判断单元222，第五计时单元221分别与状态检测单元150、第三计时计数判断单元214连接，第五时长判断单元222分别与第五计时单元221、第二计数单元215电连接，第二计数单元215还与所述状态检测单元150电连接。当第三计时计数判断单元214输出第一计数信号后，第五计时单元221收到第一计数信号后又获取电子烟由抽 吸状态进入未抽吸状态的信息，第五计时单元221被触发开始计时，同时第二计数单元215也在接收第一计数信号后又获取电子烟由抽吸状态进入未抽吸状态的信息，第二计数单元215被锁定，也即进入计数锁定状态，第二计数单元215被锁定后即使再接收到第一计数信号也不会进行计数增加，也即在锁定状态第二计数单元215保持原来的计数值，不会增加计数值，只有被解除锁定后处于计数解锁状态第二计数单元215收到第一计数信号才会计数加一。在本实施例中，当第五计时单元221开始第五计时后，第五计时单元221一直在计时(即使由未抽吸状态转为抽吸状态也在计时)，第五时长判断单元222判断第五计时单元221的计时时长是否大于或等于第五预设时长，当第五时长判断单元222判断第五计时单元221计时到达第五预设时长，第五计时单元221会停止计时并置零，也即第五计时单元221复位置零，同时，第五时长判断元输出计数解锁信号给第二计数单元215，第二计数单元215被解除对计数的锁定，第二计数单元215进入计数解锁状态，而且第三计时单元212、第三计数单元213、第二计时单元216也复位置零，此后第二计数单元215再次获取第一计数信号，第二计数单元215可以执行计数加一动作，也即第二计数在原来的基础上加一。在此实施例中，当第五计时单元221没有收到第一计数信号，或者第五计时单元221没有获取电子烟由抽吸状态进入未抽吸状态的信息，第五计时单元221也不会触发开始计时。
在本实施例中，在步骤触发进行第二计数之后还包括：判断第一计数信息位于第二预设数值范围内持续的时长是否大于或等于第七预设时长，若判断结果为是，则第二计数、第二计时均复位置零。本实施例中对重吸持续的时长进行判断，若重吸持续的时长大于或等于第七预设时长，则第二计数、第二计时均复位置零，第二计数为0，第二计时停止计时并置零，这样设置可以防止用户比较长时间抽吸后误动作进入童锁锁定状态，符合用户的使用预期。在本实施例中，第七预设时长大于或等于400ms，例如为400ms、450ms、500ms、600ms等。
在本实施例中，电子烟进入童锁锁定状态后，用户没法正常抽吸电子烟，当用户需要使用电子烟时，此时需要对电子烟进行解锁，以下描述电子烟如何进行解锁，以下描述的仅是一种进入童锁解锁状态的方式，本领域的技术人员还可以通过其他常规的方式使电子烟进入童锁解锁状态。另外，在本申请的其他实施例中，解锁方式可以与加锁方式一样，可以参见前面的描述，在此不再赘述。
请结合参阅图5和图6，在本实施例中，童锁控制方法还包括：
S21：接收第四计数信息；
其中，状态检测单元150包括第四计数判断单元231，第四计数判断单元231用于接收第四计数信息，其中，第四计数信息与第一计数信息可以是同一个计数信息，也可以是不同的计数信息，第四计数判断单元231与第二计数判断单元211可以为不同的判断单元，也可以为同一计数判断单元。在本实施例中，第四计数信息包括在第四计数时长的振荡周期数、在第四计数时长的振荡周期数与基准振荡周期数的比值、在第四计数时长的振荡周期数相对基准振荡周期的差值或者在第四计数时长内振荡周期数相对基准振荡周期数的差值与基准振荡周期数的比值，第四计数时长可以与第一计数时长相同，也可以不同。第四计数判断单元231接收第四计数信息。
在本实施例中，当处于吹气状态时，气流通道中气压较大，会高于未吸吹状态的气压，气流传感器140的电容的两个电极的间距相对未吸吹状态时要大，从而电容值会比未吸吹状态时小，频率会比未吸吹状态时大，假设第四计数时长与第一计数时长相同，则吹气状态时在第四计数时长的振荡周期数大于未吸吹状态时对应时长的振荡周期数(基准振荡周期数)，在抽吸状态时第一计数时长的振荡周期数会小于未吸吹状态时对应时长的振荡周期数(基准振荡周期数)。
S22:判断第四计数信息是否位于第四预设数值范围内，所述第四预设数值范围用于判断电子烟是否处于吹气状态；

当第四计数信息为在第四计数时长的振荡周期数，第四预设数值范围为周期数范围，第四计数时长与第一计数时长相同时，此时第四预设数值范围的下限值例如为1030、1040、1050等，会大于第一预设数值范围对应的上限值，第四预设数值范围的下限值大于基准振荡周期数；当第四计数信息为在第四计数时长的振荡周期数与基准振荡周期数的比值，第四预设数值范围为比值范围，第四计数时长与第一计数时长相同时，此时第四预设数值范围的下限值例如为1.03、1.04、1.05等，会大于第一预设数值范围对应的上限值；第四预设数值范围的上限值可以不设限，也可以根据需要设限。当第四计数信息为在第四计数时长的振荡周期数相对基准振荡周期的差值或者在第四计数时长内振荡周期数相对基准振荡周期数的差值与基准振荡周期数的比值时，此时第四预设数值范围对应为差值范围或者比值范围，此时可以参见第一计数信息的描述，本领域的技术人员根据现有知识可以知道如何区分吸气状态、吹气状态。
其中，童锁控制电路200包括第四计时单元232和第四计数单元233，第四计时单元232与第四计数判断单元231电连接，第四计数单元233与第四计数判断单元231电连接，若第四计数判断单元231的判断结果为是，则第四计数判断单元231输出吹气信号，第四计时单元232被触发开始计时，第四计时单元232从0开始计时，第四计数单元233被触发开始计数，并将此次也进行计数，也即此时第四计数单元233的计数为1；若第四计数判断单元231的判断结果为否，则第四计数判断单元231不会输出吹气信号，第四计时单元232维持原先的状态，第四计数单元233维持原先的状态。在本实施例中，当第四计时单元232被触发开始计时后，第四计时单元232会一直在计时，直到第四计时单元232被复位置零，此后第四计时单元232停止计时。在本实施例中，吹气信号也会输出给童锁控制单元240。
在本实施例中，当第四计时单元232被触发计时、第四计数单元233被触发计数后，当第四计数判断单元231又接收到第四计数信息，并又一次判断第四计数信息位于第四预设数值范围内，则第四计数单元233的第四计数加1，此时第四计数为2，同时，第四计时单元232在持续进行第四计时。
S24：判断在第四预设时长内第四计数是否大于或等于第四预设数量，其中，第四预设数量大于或等于2；
其中，童锁控制电路200还包括第四计时计数判断单元234，第四计时计数判断单元234分别与第四计数单元233、第四计时单元232电连接，当第四计时计数判断单元234判断第四计时单元232的计时时长在第四预设时长内，且第四计数单元233计数大于或等于第四预设数量，第四计时计数判断单元234输出童锁解锁信号。在本实施例中，第四预设时长一般小于或等于5s，例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第四预设数量大于或等于2，例如为2、3、4、5、6等，较佳为3，第四预设数量一般小于或等于6次，方便用户操作。
在本实施例中，第四计时计数判断单元234与第四计时单元232、第四计数单元233实时连接，当第四计时计数判断单元234获取第四计数单元233到达第四预设数量且第四计时单元232未到达第四预设时长时，第四计时计数判断单元234输出童锁解锁信号，或者第四计时计数判断单元234等第四计时单元232计时时长到达第四预设时长时才输出童锁解锁信号。在本申请的其他实施例中，第四计时计数判断单元234与第四计时单元232、第四计数单元233连接，当第四计时单元232到达第四预设时长时第四计时单元232输出信号给第四计时计数判断单元234，第四计时计数判断获取此时第四计数单元233的计数，然后判断第四计数是否大于或等于第四预设数量，若大于或等于第四预设数量，则输出童锁解锁信号，若小于第四预设数量，则维持原来的信号输出。
S24:若判断结果为是，则控制电子烟进入解锁状态，其中，在解锁状态所述电子烟处于抽吸状态时所述功率MOS管M持续导通或者间断导通。
其中，若第四计时计数判断单元234判断的结果为是，也即在第四预设时长内计数的数量大于或等于第四预设数量，则第四计时计数判断单元234输出童锁解锁信号给童锁控制单 元240，童锁控制单元240控制电子烟进入解锁状态，在解锁状态电子烟处于抽吸状态时功率MOS管M持续导通或者间断导通，也即此时功率MOS管M受用户是否抽吸的控制，在本实施例中电子烟处于抽吸状态时童锁控制单元240持续输出低电平信号或者间断输出低电平信号给功率MOS管M，功率MOS管M持续导通或者间断导通，当功率MOS管M导通时，发热元件130加热以雾化烟油，从而雾化后的烟油可供被用户抽吸。
在本实施例中，通过对吹气进行计时和计数实现解锁，在没有增加蓝牙/NFC等设计以及机械结构的同时，实现了有效的解锁效果，从而缩减了电子烟的进行解锁的硬件成本，解决现有技术中电子烟解锁成本较高的技术问题。而且，本申请的解锁方式不容易被儿童察觉，电子烟在锁定后不容易被儿童解锁，有利于提升电子烟的安全性。
在本实施例中，童锁控制方法还包括：再次获取第四计数信息位于第四预设数值范围内的信息，第四计数加1。
具体而言，在第四计数单元233触发第四计数和第四计时单元232触发第四计时后，第四计时单元232和第四计数单元233未停止工作，第四计时单元232、第四计数单元233再次(再次是指第四计数单元233中第四计数的数值至少为1)获取第四计数信息位于第四预设数值范围内的信息，则第四计数单元233在原来计数的基础上加1，例如原来第四计数单元233的计数值为1，再次获取第四计数信息位于第四预设数值范围内的信息，也即接收到由未吸吹状态转为吹气状态的信息，则第四计数单元233的计数加1，也即计数值变为2；第四计时单元232继续工作持续计时，也即第四计时单元232在触发计时后，只要不收到停止计时或者复位的信号，则第四计时单元232一直在计时。
在本实施例中，童锁控制方法还包括：若第四计时单元232的计时时长达到第四预设时长，则第四计数置零，且第四计时单元232复位置零。
其中，不论第四计时计数判断单元234的判断结果为是还是否，只要第四计时单元232的计时时长达到第四预设时长，则第四计时单元232复位置零，同时第四计时单元232发送信号给第四计数单元233，第四计数单元233进行置零，也即此时第四计时单元232停止计时，第四计数单元233停止计数，而且，计时时长置零，第四计数均置零，第四计时单元232、第四计数单元233恢复初始状态，方便后面的检测。
在本实施例中，童锁控制方法还包括：若第四计时单元232的计时时长小于第四预设时长且第四计数达到第四预设数量，则第四计数置零，且第四计时单元232复位置零。
其中，若第四计时计数判断单元234获取第四计数单元233的第四计数达到第四预设数量，且第四计时单元232计时时长小于第四预设时长，则第四计时计数判断单元234输出信号给第四计时单元232、第四计数单元233，第四计时单元232复位置零，第四计数单元233进行置零，该信号可以与童锁解锁信号一样，也可以是不同的信号。

第二实施例
本申请第二实施例提供一种电子烟，请结合参见图8和图14，电子烟包括电池110、童 锁控制电路200、发热元件130、气流传感器140、功率MOS管M1等，童锁控制电路200包括状态检测单元150。童锁控制电路200分别与电池110、气流传感器140、功率MOS管M1等电连接。在本实施例中，电池110例如为锂电池、镍镉电池、镍氢电池等可充电电池，电池110也可以为不可充电电池；状态检测单元150与气流传感器140电连接，状态检测单元150的一个具体实现方式可参见本领域的在先申请，或者为本领域技术人员知晓的其他常规的状态检测单元。在本实施例中气流传感器140为电容式气流传感器140，例如为电容式MEMS传感器或电容式咪头等，气流传感器140位于电子烟的气流通道内，气流传感器140包括电容，状态检测单元150通过电容的电容值等的变化输出对应的信号。童锁控制电路200与功率MOS管M1的控制端电连接，童锁控制电路200用于控制功率MOS管M1是否导通，功率MOS管M1经由雾化端AT与发热元件130串联形成串联支路，串联支路的一端经由电源供电端BAT与电池110的正极电连接，串联支路的另一端经由电源接地端GND与电池110的负极电连接。在本实施例中以功率MOS管M1为PMOS管为例进行说明，当然，功率MOS管M1也可以为NMOS管。在本实施例中，功率MOS管M1、童锁控制电路200可以位于同一个芯片，该芯片一般称为系统控制芯片。但本申请不限于此，在本申请的其他实施例中，功率MOS管M1、童锁控制电路200可以位于不同的芯片上。在本实施例中，发热元件130例如为发热丝、加热丝、包含发热丝或者加热丝的陶瓷座、或者其他常规的发热元件130。在本实施例中，当童锁控制电路200输出低电平控制功率MOS管M1导通时发热元件130加热以使烟油雾化，当童锁控制电路200输出高电平控制功率MOS管M1断开截止时发热元件130停止加热。
在本实施例中，状态检测单元150与气流传感器140电连接；当用户抽吸电子烟或者向电子烟吹气时，气流传感器140的电容的两个电极片之间气压相对未吸吹状态(未使用时)会改变，导致两个电极片之间的距离会随之改变，进而引起气流传感器140的电容值改变，状态检测单元150将电容值改变转换为频率值改变、计数值改变，状态检测单元150输出对应的信号，从而电子烟可以判断是否被抽吸处于抽吸状态、被吹气处于吹气状态或者处于未吸吹状态。
为了区分正常抽吸和触发进入锁定状态的抽吸，以降低正常抽吸时被误触发进入锁定状态的概率，本申请的发明人经过大量实验后提出以下方案：对电子烟的抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，气压较小(用户抽吸的吸力较小)的抽吸状态一般对应用户正常的抽吸，气压更小(用户抽吸的吸力较大)的抽吸状态对应用户想要进入锁定状态的抽吸或者用户偶然的重吸，不管是处于气压较小的抽吸状态，还是处于气压更小的抽吸状态，电子烟均会判断为抽吸状态，本申请通过当前气压信息是否位于第二预设气压范围内判断是否为气压更小的抽吸状态。
具体而言，本实施例设计当当前气压信息位于第二预设气压范围内时代表此时处于气压更小的抽吸状态，当当前气压信息位于第二预设气压范围之外且位于第一预设气压范围之内时代表气压较小的抽吸状态，其中，第二预设气压范围位于第一预设气压范围内，也即只要当前气压信息位于第二预设气压范围内，当前气压信息必然位于第一预设气压范围内，表示此时电子烟处于抽吸状态且是重吸，当当前气压信息位于第一预设气压范围内时，当前气压信息可能位于第二预设气压范围内(重吸)，也可能不位于第二预设气压范围内(正常抽吸)。
在本实施例中，当前气压信息包括当前气压值、当前气压值与基准气压值的比值、当前气压值相对基准气压值的差值或者当前气压值相对基准气压值的差值与基准气压值的比值等。当电子烟未被抽吸也未被吹气时，也即电子烟处于未吸吹状态时，此时电容的电极片未变形，此时电子烟气流通道内的气压值即为基准气压值，也即为大气压值，此时基准气压值是采集获得或者转换获得，此时预设计数时长内的振荡周期数为基准振荡周期数；另外，基准气压值也可以预设。当用户轻吸导致电子烟气流通道内的当前气压值较小时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时会变小，电容会较大，频率值会较小，预设计数时长内的振荡周期数会较小(当前计数值)，当前计数值会相对基准振荡周期数较小，此时当前气压值与基准气压值的比值会较小，当前气压值相对基准气压值的差值会 较大，当前气压值相对基准气压值的差值与基准气压值的比值会较大；当用户重吸导致电子烟气流通道内的当前气压值更小时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时会变更小，电容会更大，频率值会更小，预设计数时长内的振荡周期数会更小，当前计数值会相对基准振荡周期数更小，此时当前气压值与基准气压值的比值会更小，当前气压值相对基准气压值的差值会更大，当前气压值相对基准气压值的差值与基准气压值的比值会更大。当用户吹气导致电子烟气流通道内的当前气压值相对未吹吸状态变大时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时会变大，气流传感器140的电容会变小，频率值会变大，当前计数值会比基准振荡周期数大。
为了获得电子烟的气流通道内的当前气压信息，本实施例童锁控制电路200还包括气压获取单元241、第二气压判断单元211，气压获取单元241与状态检测单元150连接，第二气压判断单元211与气压获取单元241连接，气压获取单元241通过状态检测单元150、气流传感器140用于获取电子烟处于抽吸状态时气流通道内的当前气压信息，第二气压判断单元211用于判断当前气压信息是否位于第二预设气压范围内。具体说来，当吹气导致气流通道内气压较大时气流传感器140的电容的两个电极片之间的距离会比较大，从而其电容值会比较小，当抽吸导致气流通道内气压较小时气流传感器140电容的两个电极片之间距离比较小，从而其电容值相对会比较大，因而电容值与气流通道内的气压呈比例关系。在本申请的其他实施例中，电容值与频率值、计数值成反比例关系，从而频率值、计数值与气压也呈比例关系。在本申请的其他实施例中，处于抽吸状态的电容值相对未吸吹状态时的电容值的变化量也会与气流通道内的气压呈比例关系。在本申请的其他实施例中，处于抽吸状态的频率值相对未吸吹状态时的频率值的变化量也会与气流通道内的气压呈比例关系，或者处于抽吸状态的计数值相对未吸吹状态时的计数值的变化量也会与气流通道内的气压呈比例关系。从而通过获得电容值、电容变化量、频率值、频率变化量、计数值、计数变化量就可以对应获得气流通道内的当前气压信息，两者的对应关系可以通过公式计算获得当前气压信息，或者通过预先预存对应表格，其后查找对应表格获得当前气压信息。另外，在本申请的其他实施例中，当前气压信息也可以直接通过传感器侦测获得。
在本实施例中，气压获取单元241预存有电容值-气压值表、频率值-气压值表、计数值-气压值表、电容变化量-气压值表、频率变化量-气压值表或者计数变化量-气压值表，其中，电容值-气压值表存储电容值与气压值的对应关系，频率值-气压值表存储频率值与气压值的对应关系，计数值-气压值表存储预设计数时长的计数值与气压值的对应关系，电容变化量-气压值表存储电容变化量与气压值的对应关系，频率变化量-气压值表存储频率变化量与气压值的对应关系，计数变化量-气压值表存储预设计数时长的计数变化量与气压值的对应关系，从而当获得电容值、频率值、计数值、电容变化量、频率变化量、计数变化量时通过查表就可以对应获得当前气压值。在本实施例中，气压获取单元241、第二气压判断单元211较佳可以通过软体实现，也可以通过硬件实现。另外，在本申请的其他实施例中，气压获取单元241可以不与状态检测单元150电连接，此时气压获取单元241为气压传感器，气压传感器至少部分设置在电子烟的气流通道内，气压获取单元241可以直接获得当前气压值。
在本实施例中，通过当前气压值经过转换可以得到当前气压信息。例如，当当前气压信息为当前气压值时，此时可以直接获得当前气压信息；当当前气压信息为当前气压值与基准气压值的比值、当前气压值相对基准气压值的差值或者当前气压值相对基准气压值的差值与基准气压值的比值时，获得当前气压值后经过算数运算就可以获得当前气压信息。
当当前气压信息为当前气压值时，由于本申请设计成用户重吸才可能进入童锁锁定状态，从而第二预设气压范围为气压值的范围，第二预设气压范围的上限值要小于第一预设气压范围的上限值，第二预设气压范围的下限值大于或等于第一预设气压范围的下限值，例如第二预设气压范围为(a，A]，第一预设气压范围为(b，B],例如基准气压值为环境大气压，例如环境大气压为1个标准大气压，其中，A小于B，B小于环境大气压，a大于或等于b，A、a、B、b为正数，一般的，A比环境大气压小500pa，B比环境大气压小300pa，较佳A比环境大气压小500pa、600pa、1000pa、2000pa等。另外，在本申请的其他实施例中，第二预设气 压范围的下限值不设限，也即当当前气压信息小于A即落入第二预设气压范围内。另外，当当前气压信息为当前气压值与基准气压值的比值时，第二预设气压范围为比值范围，其原理与前面描述的当前气压信息为当前气压值的方案类似，在此不再赘述，此比值较佳小于或等于0.95，例如为0.9、0.8、0.7等。
当当前气压信息为当前气压值相对基准气压值的差值时，当气流通道内气压更小时，差值会更大，当气流通道内气压较小时，差值会较大，因而当前气压信息与气流通道内的气压呈比例关系。此时第二预设气压范围为差值范围，第二预设气压范围的下限值大于第一预设气压范围的下限值，第二预设气压范围的上限值小于或等于第一预设气压范围的上限值，例如第二预设气压范围为[M,m)，例如M为500pa，第一预设气压范围[N,n),例如N为300pa，其中，M大于N，m小于或等于n，M、m、N、n为正数。另外，在本申请的其他实施例中，第二预设气压范围的上限值不设限，也即只要当前气压信息大于或等于M即落入第二预设气压范围内。另外，当当前气压信息为当前气压值相对基准气压值的差值与基准气压值的比值时，第二预设气压范围为比值范围，其原理与前面描述的当前气压信息为当前气压值相对基准气压值的差值的方案类似，在此不再赘述，此比值较佳大于或等于0.05，例如为0.1、0.2、0.3等。
请结合参见图8、图9和图14，本申请实施例提供一种电子烟的童锁控制方法，包括以下步骤：S11：接收电子烟气流通道内的当前气压信息；
其中，气压获取单元241与状态检测单元150连接，状态检测单元150输出当前电容值、当前电容变化量、当前频率值、当前频率变化量、当前计数值(预设计数时长的振荡周期数)或者当前计数变化量给气压获取单元241，气压获取单元241根据预存的电容值-气压值表、电容变化量-气压值表、频率值-气压值表、频率变化量-气压值表、计数值-气压值表或者计数变化量-气压值表，通过查表可以得到电子烟气流通道内的当前气压值，进而获得当前气压信息。另外，在本申请的其他实施例中，气压获取单元241不与状态检测单元150连接，气压获取单元241本身就可以直接得到当前气压值，进而获得当前气压信息。本实施例利用现有的气流传感器140、状态检测单元150输出的当前电容值、当前电容变化量、当前频率值、当前频率变化量、当前计数值或者当前计数变化量，通过简单改变就可以获得当前气压信息，有利于降低成本。
在本实施例中，第二气压判断单元211与气压获取单元241连接，气压获取单元241产生当前气压信息，并输出当前气压信息，第二气压判断单元211接收当前气压信息。
S12:判断当前气压信息是否位于第二预设气压范围内，其中，所述第二预设气压范围位于第一预设气压范围内，所述第一预设气压范围用于判断电子烟是否处于抽吸状态；
S13：若判断结果为是，则触发进行第二计时并触发进行第二计数；
其中，第二气压判断单元211在接收到当前气压信息后，第二气压判断单元211判断当前气压信息是否位于第二预设气压范围内，第二预设气压范围为预先计算获得，或者预先存储在第二气压判断单元211中。其中，童锁控制电路200包括第二计时单元216和第二计数单元215，第二计时单元216与第二气压判断单元211电连接，第二计数单元215与第二气压判断单元211电连接，若第二气压判断单元211的判断结果为是，则第二气压判断单元211输出气压有效信号，第二计时单元216被触发开始计时，第二计时单元216从0开始计时，第二计数单元215被触发开始计数，并将此次也进行计数，也即此时第二计数单元215的计数为1；若第二气压判断单元211的判断结果为否，则第二气压判断单元211输出气压无效信号，第二计时单元216维持原先的状态，第二计数单元215维持原先的状态。在本实施例中，当第二计时单元216被触发开始计时后，第二计时单元216会一直在计时，直到第二计时单元216被复位置零，此后第二计时单元216停止计时。
当第二计时单元216被触发计时、第二计数单元215被触发计数后，当第二气压判断单元211又接收到当前气压信息，并又一次判断当前气压信息位于第二预设气压范围内，也即又输出气压有效信号，则第二计数单元215的第二计数加1，此时第二计数为2，同时，第二计时单元216在持续进行第二计时。
S14：判断在第二预设时长内第二计数是否大于或等于第二预设数量，其中，第二预设数量大于或等于2；
其中，童锁控制电路200还包括第二计时计数判断单元217，第二计时计数判断单元217分别与第二计数单元215、第二计时单元216连接，当第二计时计数判断单元217判断第二计时单元216的计时时长在第二预设时长内，且第二计数单元215的第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号。在本实施例中，第二预设时长一般小于或等于5s，第二预设时长例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第二预设数量为大于或等于2的整数，例如为2、3、4、5、6等，较佳为3，第二预设数量一般小于或等于6次，方便用户操作。例如，第二预设时长为2秒，第二预设数量为3，则在2秒内第二计数大于或等于3，第二计时计数判断单元217输出童锁锁定信号。
在本实施例中，第二计时计数判断单元217与第二计时单元216、第二计数单元215实时电连接，当第二计时计数判断单元217获取第二计数到达第二预设数量且第二计时单元216未到达第二预设时长时，第二计时计数判断单元217输出童锁锁定信号，或者第二计时计数判断单元217等第二计时单元216计时时长到达第二预设时长时才输出童锁锁定信号。在本申请的其他实施例中，第二计时计数判断单元217与第二计时单元216、第二计数单元215连接，当第二计时单元216到达第二预设时长时第二计时单元216输出信号给第二计时计数判断单元217，第二计时计数判断单元217获取此时第二计数单元215的第二计数，然后判断第二计数是否大于或等于第二预设数量，若第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号，若第二计数小于第二预设数量，则第二计时计数判断单元217维持原来的信号输出。
S15：若判断结果为是，则控制电子烟进入锁定状态，在锁定状态所述功率MOS管M1保持断开截止。
其中，童锁控制电路200还包括童锁控制单元240，童锁控制单元240与第二计时计数判断单元217电连接。若第二计时计数判断单元217的判断结果为是，也即在第二预设时长内第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号给童锁控制单元240，童锁控制单元240控制电子烟进入锁定状态，在锁定状态功率MOS管M1保持断开，在本实施例中童锁控制单元240持续输出高电平信号给功率MOS管M1，功率MOS管M1保持截止。在本实施例中，童锁控制单元240包括触发器和开关控制单元，触发器用于对童锁锁定信号、后续的童锁解锁信号进行保持，触发器例如为SR触发器等，开关控制单元与触发器电连接，开关控制单元还接收抽吸信号(抽吸状态时输出的信号)、吹气信号(吹气状态时输出的信号)或者未吸吹信号(未使用时输出的信号)，开关控制单元例如为与门、与非门、或门、或非门等，例如，开关控制单元包括与非门，与非门的第一输入端与触发器的输出端连接，与非门的第二输入端接收抽吸信号、吹气信号或者未吸吹信号，童锁锁定信号使触发器的输出保持为低电平，从而经过与非门后保持为高电平(此时第二输入端接收抽吸信号，抽吸信号例如为高电平)，功率MOS管M1保持截止；童锁解锁信号使触发器的输出保持为高电平，从而与非门的输出受电子烟的抽吸、吹气状态的影响，当用户抽吸电子烟时，与非门的第二输入端接收抽吸信号，抽吸信号为高电平，此时开关控制单元控制功率MOS管M1持续导通或者间断导通(例如PWM、PFM控制方式)。若第二计时计数判断单元217的判断结果为否，也即在第二预设时长内第二计数小于第二预设数量，则维持电子烟原先的童锁状态，且第二计数置0，第二计时复位置零。
在本实施例中，电子烟的童锁状态分为锁定状态和解锁状态，其中，锁定状态即对应童锁保护功能，当电子烟处于锁定状态时用户抽吸电子烟，童锁控制单元240继续控制功率MOS管M1保持断开截止，从而发热元件130不会加热，进而烟油不会雾化以供用户抽吸，也即即使用户抽吸电子烟也不会出现烟雾。解锁状态对应解除童锁保护功能，此时烟油是否雾化受是否抽吸的控制，当用户抽吸电子烟时，童锁控制单元240控制功率MOS管M1持续导通或者间断导通，间断导通是指童锁控制单元240通过PWM方式、PFM方式输出方波信号， 通过调整方波信号的占空比以用于控制输出功率、输出电压。
在本实施例中，通过接收电子烟气流通道内的当前气压信息；判断当前气压信息是否位于第二预设气压范围内，若判断结果为是，则触发进行第二计时并触发进行第二计数；判断在第二预设时长内第二计数是否大于或等于第二预设数量，若判断结果为是，则控制电子烟进入锁定状态。本申请实施例通过当前气压信息、第二预设气压范围对抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，将当前气压信息位于第二预设气压范围的抽吸次数分辨为气压更小的抽吸状态(重吸)，并进行第二计数，并且在第二预设时长内第二计数大于或等于第二预设数量才使电子烟进入锁定状态，通过这样设置，电子烟可以进一步分辨用户是正常抽吸电子烟，还是想要通过抽吸电子烟触发烟进入锁定状态，电子烟不容易混淆两者，可以降低用户正常抽吸电子烟时被误触发进入锁定状态的几率，可以减少用户的使用困扰。而且，通过在第二预设时长内第二计数大于或等于第二预设数量，可以实现电子烟进入锁定状态，本实施例的电子烟在锁定保护后，可以防止儿童拿起电子烟模仿成人抽吸动作导致电子烟产品开始雾化工作，提升电子烟的使用安全性。而且，本实施例利用现有的状态检测单元150、气流传感器140经过转换就可以得到当前气压信息，不需要对电子烟进行大改，不需要增加硬件成本或者增加的硬件成本很小，从而缩减了电子烟进行锁定保护的硬件成本，解决现有技术中电子烟锁定成本较高的技术问题。
在本实施例中，童锁控制方法还包括：再次获取当前气压信息位于第二预设气压范围内的信息，第二计数加1。
具体而言，在第二计数单元215触发第二计数和第二计时单元216触发第二计时后，第二计时单元216和第二计数单元215未停止工作，当电子烟转为未抽吸状态，其后，当用户再次抽吸电子烟，再次实时获取当前气压信息，若第二计数单元215再次获取当前气压信息位于第二预设气压范围内的信息，也即第二计数单元215又收到气压有效信号，则第二计数单元215在原来第二计数的基础上加1，例如原来第二计数单元215的计数值为1，再次获取当前气压信息位于第二预设气压范围内的信息，则第二计数单元215的第二计数加1，也即第二计数变为2，同时，第二计时单元216在触发第二计时后，第二计时单元216一直在计时；若此次第二计数单元215没有获取当前气压信息位于第二预设气压范围内的信息，也即第二计数单元215没有收到气压有效信号，则第二计数保持不变，此时第二计时单元216也在计时。
在本实施例中，童锁控制方法还包括：若第二计时达到第二预设时长，则第二计数置零，且第二计时复位置零。
其中，不论第二计时计数判断单元217的判断结果为是还是不为是，只要第二计时单元216的计时时长达到第二预设时长，则第二计时单元216复位置零，同时第二计时单元216发送信号给第二计数单元215，第二计数单元215进行置零，也即此时第二计时单元216停止计时，计时时长置零，第二计时单元216、第二计数单元215恢复初始状态，方便后面信号的检测。在本实施例中，第二计时计数判断单元217在第二计时单元216、第二计数单元215复位置零前已完成判断。
在本实施例中，童锁控制方法还包括：若第二计时小于第二预设时长且第二计数达到第二预设数量，则第二计数置零，且第二计时复位置零。
其中，若第二计时计数判断单元217获取第二计数达到第二预设数量，且第二计时单元216计时时长小于第二预设时长，则第二计时计数判断单元217输出信号给第二计时单元216、第二计数单元215，第二计时单元216进行复位置零，第二计数单元215置零，该信号可以与童锁锁定信号一样，也可以是不同的信号。
在应用上述的方案进行实际测试过程中发明人发现：由于空气中气流的扰动，可能会导致处于抽吸状态时瞬间的气压下降，导致当前气压信息到达第二预设气压范围，这个瞬间的气压下降持续时间很短，一般偶尔的一次，造成第二计数单元215误计数，可能误触发电子烟进入锁定状态，给用户的使用造成困扰。为了解决该问题，请结合参阅图10和图14，步骤触发进行第二计数具体包括：S131:触发进行第三计时并触发进行第三计数；
其中，童锁控制电路200还包括第三计时单元212和第三计数单元213，第三计时单元212、第三计数单元213均与第二气压判断单元211连接，当第三计时单元212、第三计数单元213获取当前气压信息位于第二预设气压范围内时，也即第三计时单元212接收到气压有效信号时，第三计时单元212开始第三计时，第三计时单元212一直计时，直到进行复位置零，此后第三计时单元212停止计时；第三计数单元213接收到气压有效信号时，第三计数单元213开始第三计数，且此次也进行第三计数，此时第三计数为1。
S132:判断在第三预设时长内第三计数是否大于或等于第三预设数量；
其中，童锁控制电路200还包括第三计时计数判断单元214，第三计时计数判断单元214分别与第三计数单元213、第三计时单元212连接，当第三计时计数判断单元214判断第三计时单元212的计时时长在第三预设时长内，且第三计数单元213的第三计数大于或等于第三预设数量，则第三计时计数判断单元214输出第一计数信号。在本实施例中，第三预设时长一般为30ms-150ms，第三预设时长例如为30ms、40ms、50ms、60ms、70ms、80ms、90ms、100ms、110ms、120ms、130ms、140ms、150ms等，较佳为60ms-100ms。在本实施例中，第三预设数量为大于或等于2的整数，例如为2、3等。在本实施例中，第三预设数量大于或等于2，例如为2、3、4、5、6等。
在本实施例中，第三计时计数判断单元214与第三计时单元212、第三计数单元213实时电连接，当第三计时计数判断单元214获取第三计数到达第三预设数量且第三计时未到达第三预设时长时，第三计时计数判断单元214输出第一计数信号，或者第三计时计数判断单元214等第三计时到达第三预设时长时才输出第一计数信号。在本申请的其他实施例中，第三计时计数判断单元214与第三计时单元212、第三计数单元213连接，当第三计时单元212到达第三预设时长时第三计时单元212输出信号给第三计时计数判断单元214，第三计时计数判断单元214获取此时第三计数单元213的第三计数，然后判断第三计数是否大于或等于第三预设数量，若第三计数大于或等于第三预设数量，则第三计时计数判断单元214输出第一计数信号，若第三计数小于第三预设数量，则第三计时复位置零，第三计数置零。
S133:若判断结果为是，则触发进行第二计数。
其中，第三计时计数判断单元214与第二计时单元216、第二计数单元215连接。若第三计时计数判断单元214的判断结果为是，则第二计时单元216接收到第一计数信号，第二计时单元216被触发开始计时，第二计时从0开始计时；第二计数单元215接收到第一计数信号，第二计数单元215被触发开始计数，此时第二计数单元215对本次也进行计数，也即此时第二计数为1。
在本实施例中，当此前第二计数单元215没有被触发开始计数，第二计时单元216没有被触发开始计时，若第三计时计数判断单元214的判断结果为否，也即第三计时计数判断单元214不输出第一计数信号，第二计数单元215维持原来不进行计数，第二计时单元216维持原来不进行计时；当此前第二计数单元215已被触发开始计数(也即第二计数至少为1)，第二计时单元216已被触发计时，若第三计时计数判断单元214的判断结果为否，则第二计数维持原来的计数，第二计数不增加，第二计时继续计时。
在本实施例中，当空气气流串扰导致电子烟气流通道内气压短时间变化时，由于气压降低的时长很短，从而不会符合在第三预设时长内第三计数大于或等于第三预设数量的条件，从而第二计数不会变化，从而不会将空气气流串扰误判为用户想要进入童锁保护的情况，可以防止电子烟误进入锁定状态，可以防止对用户的使用造成困扰，本实施例可以避免这种情况发生，提升了用户的使用体验。
在本实施例中，在整个第三预设时长电子烟处于抽吸状态，在第三预设时长的部分时长或者整个时长均属于重吸，则第二计时单元216进行计数。
为了判断电子烟是否处于抽吸状态，请结合参见图11和图14，在本实施例中，童锁控制方法还包括:S171:接收电子烟气流通道内的当前气压信息；
S172:判断当前气压信息是否位于第一预设气压范围内；
S173：若判断结果为是，则输出电子烟由未抽吸状态转为抽吸状态的信息。
其中，童锁控制电路200包括第一气压判断单元242，第一气压判断单元242与气压获取单元241连接，气压获取单元241输出当前气压信息后，第一气压判断单元242接收当前气压信息，第一气压判断单元242判断当前气压信息是否位于第一预设气压范围内，若判断结果为是，则第一气压判断单元242输出电子烟由未抽吸状态转为抽吸状态的信息，也即输出抽吸信号，若判断结果为否，则第一气压判断单元242维持原来的信号输出，例如输出未吸吹信号、吹气信号。在本实施例中，第一气压判断单元242与童锁控制单元240连接，具体与童锁控制单元240的开关控制单元连接。进一步的，还可以要求连续多次判断为是，才输出抽吸信号，这样有利于降低气流串扰误触发的几率。在本实施例中，第一气压判断单元242、第二气压判断单元211可以为同一判断单元，也可以为不同的判断单元。
另外，在本申请的其他实施例中，可以与现有技术一样，通过状态检测单元150直接判断电子烟是否处于抽吸状态、吹气状态，具体说来，童锁控制方法还包括:
接收当前计数值，其中，所述当前计数值用于表征电子烟气流通道内的气压大小；
判断当前计数值是否位于第一预设数值范围内，其中，所述第一预设数值范围与所述第一预设气压范围对应；
若判断结果为是，则输出电子烟由未抽吸状态转为抽吸状态的信息。
其中，状态检测单元150包括第一计数生成单元、第一计数判断单元，第一计数生成单元与第一计数判断单元连接，第一计数生成单元生成当前计数值后，第一计数判断单元接收当前计数值，第一计数判断单元判断当前计数值是否位于第一预设数值范围内，第一预设数值范围与第一预设气压范围呈对应关系，也即通过第一预设数值范围经过转换可以得到第一预设气压范围，通过第一预设气压范围经过转换也可以得到第一预设数值范围。若第一计数判断单元的判断结果为是，则第一计数判断单元输出电子烟由未抽吸状态转为抽吸状态的信息，也即输出抽吸信号，若判断结果为否，则第一计数判断单元维持原来的信号输出，例如输出未吸吹信号、吹气信号。进一步的，还可以要求连续多次判断为是，才输出抽吸信号，这样有利于降低气流串扰误触发的几率。在本实施例中，当前计数值为预设计数时长的振荡周期的计数值，这是本领域的常规技术，在此不再赘述。另外，在现有技术中，同样可以通过当前计数值判断电子烟是否处于吹气状态，例如当前气压值位于第四预设数值范围内时，此时电子烟处于吹气状态，输出吹气信号。
另外，在本实施例中，请结合参阅图12和图14，在步骤触发进行第二计数之后还包括：
S161:获取电子烟由抽吸状态进入未抽吸状态的信息；
S162:触发第五计时且对第二计数进行锁定；
S163:判断第五计时是否大于或等于第五预设时长；
S164:若判断结果为是，则解除对第二计数的锁定。
本实施例还对两次抽吸状态(包含两次重吸)之间的间隔时长进行规定，防止抽吸状态时气流抖动、串扰等而导致误第二计数。具体而言，在本实施例中，童锁控制电路200包括第五计时单元221和第五时长判断单元222，第五计时单元221分别与第一气压判断单元242、第三计时计数判断单元214连接，第五时长判断单元222分别与第五计时单元221、第二计数单元215电连接，第二计数单元215还与第一气压判断单元242电连接。当第三计时计数判断单元214输出第一计数信号后，第五计时单元221收到第一计数信号后又获取电子烟由抽吸状态进入未抽吸状态的信息，第五计时单元221被触发开始计时，同时第二计数单元215也在接收第一计数信号后又获取电子烟由抽吸状态进入未抽吸状态的信息，第二计数单元215被锁定，也即进入计数锁定状态，第二计数单元215被锁定后即使再接收到第一计数信号也不会进行计数增加，也即在锁定状态第二计数单元215保持原来的计数值，不会增加计数值，只有被解除锁定后处于计数解锁状态第二计数单元215收到第一计数信号才会计数加一。在本实施例中，当第五计时单元221开始第五计时后，第五计时单元221一直在计时(即使由未抽吸状态转为抽吸状态也在计时)，第五时长判断单元222判断第五计时单元221的计时时长是否大于或等于第五预设时长，当第五时长判断单元222判断第五计时单元221计时到达第五预设时长，第五计时单元221会停止计时并置零，也即第五计时单元221复位置零， 同时，第五时长判断元输出计数解锁信号给第二计数单元215，第二计数单元215被解除对计数的锁定，第二计数单元215进入计数解锁状态，而且第三计时单元212、第三计数单元213、第二计时单元216也复位置零，此后第二计数单元215再次获取第一计数信号，第二计数单元215可以执行计数加一动作，也即第二计数在原来的基础上加一。在此实施例中，当第五计时单元221没有收到第一计数信号，或者第五计时单元221没有获取电子烟由抽吸状态进入未抽吸状态的信息，第五计时单元221也不会触发开始计时。
在本实施例中，在步骤触发进行第二计数之后还包括：判断当前气压信息位于第二预设气压范围内持续的时长是否大于或等于第七预设时长，若判断结果为是，则第二计数、第二计时均复位置零。本实施例中对重吸持续的时长进行判断，若重吸持续的时长大于或等于第七预设时长，则第二计数、第二计时均复位置零，第二计数为0，第二计时停止计时并置零，这样设置可以防止用户比较长时间抽吸后误动作进入童锁锁定状态，符合用户的使用预期。在本实施例中，第七预设时长大于或等于400ms，例如为400ms、450ms、500ms、600ms等。
在本实施例中，电子烟进入童锁锁定状态后，用户没法正常抽吸电子烟，当用户需要使用电子烟时，此时需要对电子烟进行解锁，以下描述电子烟如何进行解锁，以下描述的仅是一种进入童锁解锁状态的方式，本领域的技术人员还可以通过其他常规的方式使电子烟进入童锁解锁状态。另外，在本申请的其他实施例中，解锁方式可以与加锁方式一样，可以参见前面的描述，在此不再赘述。
请结合参阅图13和图14，在本实施例中，童锁控制方法还包括：

其中，童锁控制电路200包括第四气压判断单元231，第四气压判断单元231用于接收当前气压信息，其中，第四气压判断单元231与第二气压判断单元211可以为不同的判断单元，也可以为同一气压判断单元。
在本实施例中，当处于吹气状态时，气流通道中气压较大，会高于未吸吹状态的气压，也即当前气压值会大于基准气压值，气流传感器140的电容的两个电极的间距相对未吸吹状态时要大，从而电容值会比未吸吹状态时小，频率会比未吸吹状态时大，吹气状态时在预设计数时长内的振荡周期数(当前计数值)大于未吸吹状态时对应时长的振荡周期数(基准振荡周期数)，在抽吸状态时预设计数时长内的振荡周期数(当前计数值)会小于未吸吹状态时对应时长的振荡周期数(基准振荡周期数)。
S22:判断当前气压信息是否位于第四预设气压范围内，所述第四预设气压范围用于判断电子烟是否处于吹气状态；

当当前气压信息为当前气压值时，第四预设气压范围为气压值范围，此时第四预设气压范围的下限值例如为1.03倍基准气压值等，会大于第一预设气压范围对应的上限值，第四预设气压范围的下限值大于基准气压值；当当前气压信息为当前气压值与基准气压值的比值时，第四预设气压范围为比值范围，此时第四预设气压范围的下限值例如为1.03、1.04、1.05等，会大于第一预设气压范围对应的上限值；第四预设气压范围的上限值可以不设限，也可以根据需要设限。当当前气压信息为当前气压值相对基准气压值的差值或者当前气压值相对基准气压值的差值与基准气压值的比值时，第四预设气压范围对应为差值范围或者比值范围，此时可以参见前面的描述，本领域的技术人员根据现有知识可以知道如何区分吸气状态、吹气状态。
其中，童锁控制电路200包括第四计时单元232和第四计数单元233，第四计时单元232与第四气压判断单元231电连接，第四计数单元233与第四气压判断单元231电连接，若第四气压判断单元231的判断结果为是，则第四气压判断单元231输出吹气信号，第四计时单元232被触发开始计时，第四计时单元232从0开始计时，第四计数单元233被触发开始计 数，并将此次也进行计数，也即此时第四计数单元233的计数为1；若第四气压判断单元231的判断结果为否，则第四气压判断单元231不会输出吹气信号，第四计时单元232维持原先的状态，第四计数单元233维持原先的状态。在本实施例中，当第四计时单元232被触发开始计时后，第四计时单元232会一直在计时，直到第四计时单元232被复位置零，此后第四计时单元232停止计时。在本实施例中，吹气信号也会输出给童锁控制单元240。另外，在本申请的其他实施例中，状态检测单元150可以通过当前计数值是否位于第四预设数值范围内，判断电子烟是否处于吹气状态，其中，第四预设数值范围与第四预设气压范围对应；当判断为吹气状态时，状态检测单元150输出吹气信号，这是本领域的常规技术，在此不再赘述。
在本实施例中，当第四计时单元232被触发计时、第四计数单元233被触发计数后，当第四气压判断单元231又接收到当前气压信息，并又一次判断当前气压信息位于第四预设气压范围内，则第四计数单元233的第四计数加1，此时第四计数为2，同时，第四计时单元232在持续进行第四计时。
S24：判断在第四预设时长内第四计数是否大于或等于第四预设数量，其中，第四预设数量大于或等于2；
其中，童锁控制电路200还包括第四计时计数判断单元234，第四计时计数判断单元234分别与第四计数单元233、第四计时单元232电连接，当第四计时计数判断单元234判断第四计时单元232的计时时长在第四预设时长内，且第四计数单元233计数大于或等于第四预设数量，第四计时计数判断单元234输出童锁解锁信号。在本实施例中，第四预设时长一般小于或等于5s，例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第四预设数量大于或等于2，例如为2、3、4、5、6等，较佳为3，第四预设数量一般小于或等于6次，方便用户操作。
在本实施例中，第四计时计数判断单元234与第四计时单元232、第四计数单元233实时连接，当第四计时计数判断单元234获取第四计数单元233到达第四预设数量且第四计时单元232未到达第四预设时长时，第四计时计数判断单元234输出童锁解锁信号，或者第四计时计数判断单元234等第四计时单元232计时时长到达第四预设时长时才输出童锁解锁信号。在本申请的其他实施例中，第四计时计数判断单元234与第四计时单元232、第四计数单元233连接，当第四计时单元232到达第四预设时长时第四计时单元232输出信号给第四计时计数判断单元234，第四计时计数判断获取此时第四计数单元233的计数，然后判断第四计数是否大于或等于第四预设数量，若大于或等于第四预设数量，则输出童锁解锁信号，若小于第四预设数量，则维持原来的信号输出。
S24:若判断结果为是，则控制电子烟进入解锁状态，其中，在解锁状态所述电子烟处于抽吸状态时所述功率MOS管M1持续导通或者间断导通。
其中，若第四计时计数判断单元234判断的结果为是，也即在第四预设时长内计数的数量大于或等于第四预设数量，则第四计时计数判断单元234输出童锁解锁信号给童锁控制单元240，童锁控制单元240控制电子烟进入解锁状态，在解锁状态电子烟处于抽吸状态时功率MOS管M1持续导通或者间断导通，也即此时功率MOS管M1受用户是否抽吸的控制，在本实施例中电子烟处于抽吸状态时童锁控制单元240持续输出低电平信号或者间断输出低电平信号给功率MOS管M1，功率MOS管M1持续导通或者间断导通，当功率MOS管M1导通时，发热元件130加热以雾化烟油，从而雾化后的烟油可供被用户抽吸。
在本实施例中，通过对吹气进行计时和计数实现解锁，在没有增加蓝牙/NFC等设计以及机械结构的同时，实现了有效的解锁效果，从而缩减了电子烟的进行解锁的硬件成本，解决现有技术中电子烟解锁成本较高的技术问题。而且，本申请的解锁方式不容易被儿童察觉，电子烟在锁定后不容易被儿童解锁，有利于提升电子烟的安全性。另外，在本申请的其他实施例中，同判断抽吸状态一样，也可以通过当前计数值来判断是否进行吹气。
在本实施例中，童锁控制方法还包括：再次获取当前气压信息位于第四预设气压范围内的信息，第四计数加1。
具体而言，在第四计数单元233触发第四计数和第四计时单元232触发第四计时后，第四计时单元232和第四计数单元233未停止工作，第四计时单元232、第四计数单元233再次(再次是指第四计数单元233中第四计数的数值至少为1)获取当前气压信息位于第四预设气压范围内的信息，则第四计数单元233在原来计数的基础上加1，例如原来第四计数单元233的计数值为1，再次获取当前气压信息位于第四预设气压范围内的信息，也即接收到由未吸吹状态转为吹气状态的信息，则第四计数单元233的计数加1，也即计数值变为2；第四计时单元232继续工作持续计时，也即第四计时单元232在触发计时后，只要不收到停止计时或者复位的信号，则第四计时单元232一直在计时。
在本实施例中，童锁控制方法还包括：若第四计时单元232的计时时长达到第四预设时长，则第四计数置零，且第四计时单元232复位置零。
在本实施例中，童锁控制方法还包括：若第四计时单元232的计时时长小于第四预设时长且第四计数达到第四预设数量，则第四计数置零，且第四计时单元232复位置零。

本申请实施例还提供一种电子烟，请结合参见图8和图14，电子烟包括上述的童锁控制电路200，电子烟还包括电池110、功率MOS管M1和发热元件130，发热元件130和功率MOS管M1串联形成发热支路，发热支路的两端对应与电池110的正、负极电连接；还包括气流传感器140，其中，功率MOS管M1的控制端、气流传感器140均与童锁控制电路200电连接，所述气流传感器140与童锁控制电路200的状态检测单元150电连接。
第三实施例
本申请第三实施例提供一种电子烟，请结合参见图16和图22，电子烟包括电池110、童锁控制电路200、发热元件130、气流传感器140、功率MOS管M1等，童锁控制电路200包括状态检测单元150。童锁控制电路200分别与电池110、气流传感器140、功率MOS管M1等电连接。在本实施例中，电池110例如为锂电池、镍镉电池、镍氢电池等可充电电池，电池110也可以为不可充电电池；状态检测单元150与气流传感器140电连接，状态检测单元150用于判断电子烟是否被抽吸和/或被吹气，并输出对应信号，状态检测单元150的一个具体实现方式可参见本领域的在先申请，或者为本领域技术人员知晓的其他常规的状态检测单元。在本实施例中气流传感器140为电容式气流传感器140，例如为电容式MEMS传感器或电容式咪头等，气流传感器140位于电子烟的气流通道内，气流传感器140包括电容，状态检测单元150通过电容的电容值等的变化判断电子烟是否处于抽吸状态、吹气状态、未吸吹状态(对应用户未使用时的状态)。童锁控制电路200与功率MOS管M1的控制端电连接，童锁控制电路200用于控制功率MOS管M1是否导通，功率MOS管M1经由雾化端AT与发热元件130串联形成串联支路，串联支路的一端经由电源供电端BAT与电池110的正极电连接，串联支路的另一端经由电源接地端GND与电池110的负极电连接。在本实施例中以功率MOS管M1为PMOS管为例进行说明，当然，功率MOS管M1也可以为NMOS管。在本实施例中，功率MOS管M1、童锁控制电路200可以位于同一个芯片，该芯片一般称为系统控制芯片。但本申请不限于此，在本申请的其他实施例中，功率MOS管M1、童锁控制电路200可以位于不同的芯片上。在本实施例中，发热元件130例如为发热丝、加热丝、包含发热丝或者加热丝的陶瓷座、或者其他常规的发热元件130。在本实施例中，当童锁控制电 路200输出低电平控制功率MOS管M1导通时发热元件130加热以使烟油雾化，当童锁控制电路200输出高电平控制功率MOS管M1断开截止时发热元件130停止加热。
在本实施例中，状态检测单元150与气流传感器140电连接，以用于判断电子烟是否被抽吸或者被吹气或者处于未吹气也未抽吸的状态(未吸吹状态)，当用户抽吸电子烟或者向电子烟吹气时，气流传感器140的电容的两个电极片之间气压会改变，导致两个电极片之间的距离会随之改变，进而引起气流传感器140的电容值改变，状态检测单元150将电容值改变转换为频率值改变或者计数值改变，通过将电容值、频率值或者计数值与预设的参数范围进行比较，状态检测单元150就可以判断电子烟是否被抽吸处于抽吸状态、被吹气处于吹气状态或者处于未吸吹状态。
为了区分正常抽吸和触发进入锁定状态的抽吸，以降低正常抽吸时被误触发进入锁定状态的概率，本申请的发明人经过大量实验后提出以下方案：对电子烟的抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，气压较小(用户抽吸的吸力较小)的抽吸状态一般对应用户正常的抽吸，气压更小(用户抽吸的吸力较大)的抽吸状态对应用户想要进入锁定状态的抽吸或者用户偶然的重吸，不管是处于气压较小的抽吸状态，还是处于气压更小的抽吸状态，电子烟均会判断为抽吸状态，本申请通过第一参数信息是否位于第二预设参数范围内判断是否为气压更小的抽吸状态。
具体而言，第一参数信息表征电子烟气流通道内的气压状况，气压状况例如为气压大小、气压的变化状况等，第一参数信息与气流通道内的气压状况呈对应关系，本实施例设计当第一参数信息位于第二预设参数范围内时代表此时处于气压更小的抽吸状态，当第一参数信息位于第二预设参数范围之外且位于第一预设参数范围之内时代表气压较小的抽吸状态，其中，第二预设参数范围位于第一预设参数范围内，也即只要第一参数信息位于第二预设参数范围内，第一参数信息必然位于第一预设参数范围内，表示此时电子烟处于抽吸状态且是重吸，当第一参数信息位于第一预设参数范围内时，第一参数信息可能位于第二预设参数范围内(重吸)，也可能不位于第二预设参数范围内(正常抽吸)。
在本实施例中，第一参数信息包括当前电容值、当前频率值、当前计数值、当前电容值与基准电容值的比值、当前频率值与基准频率值的比值、当前计数值与基准计数值的比值、当前电容值与基准电容值的差值、当前频率值与基准频率值的差值、当前计数值与基准计数值的差值、当前电容值相对基准电容值的差值与基准振荡电容值的比值、当前频率值相对基准频率值的差值与基准频率值的比值或者当前计数值相对基准计数值的差值与基准计数值的比值等，或者当前电容值、当前频率值或者当前计数值的变形。当电子烟未被抽吸也未被吹气时，也即电子烟处于未吸吹状态时，此时电容的电极片未变形，此时的当前电容值即为基准电容值，此时基准电容值是采集获得或者转换获得，此时对应的当前频率值即为基准频率值，此时预设计数时长的振荡周期数为当前计数值，也为基准计数值；另外，基准电容值、基准频率值、基准计数值也可以预设。当用户轻吸导致电子烟气流通道内的当前气压较小时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变小，当前电容值会较大，当前电容值与基准电容值的比值会较大，当前频率值会较小，预设计数时长的振荡周期数会较小，也即当前计数值会较小，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会较小，对应差值会较大，对应差值与对应基准值的比值会较大；当用户重吸导致电子烟气流通道内的当前气压值更小时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变更小，当前电容值会更大，当前电容值与基准电容值的比值会更大，当前频率值会更小，预设计数时长的振荡周期数会更小，当前计数值会更小，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会更小，对应差值会更大，对应差值与对应基准值的比值会更大。当用户吹气导致电子烟气流通道内的当前气压值相对未吹吸状态变大时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变大，气流传感器140的当前电容值会变小，当前频率值会变大，当前计数值会比基准计数值大。
当气流通道内气压更小时气流传感器140的电容变形更大，电容的两个电极片之间的距离更小，从而其当前电容值会更大，当前电容值与基准电容值的比值会更大，当前计数值会 更小，当前频率值会更小，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会更小，对应差值会更大，对应差值与对应基准值的比值会更大；当气流通道内气压较小时气流传感器140的电容变形较大，电容的两个电极片之间的距离较小，从而其电容值会较大，当前电容值与基准电容值的比值会较大，当前计数值会较小，当前频率值会较小，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会较小，对应差值会较大，对应差值与对应基准值的比值会较大。因而当前电容值、当前计数值、当前频率值等均与气流通道内的气压呈比例关系。
由于本申请设计成用户重吸才可能进入童锁锁定状态，当第一参数信息为当前电容值时，第二预设参数范围对应为电容值范围，第二预设参数范围的下限值要大于第一预设参数范围的下限值，第二预设参数范围的上限值小于或等于第一预设参数范围的上限值，例如第二预设参数范围为(a，A]，第一预设参数范围(b，B],其中，a大于b，A小于或等于B，A、a、B、b为正数。当所述第一参数信息为当前电容值与基准电容值的差值、当前频率值与基准频率值的差值、当前计数值与基准计数值的差值、当前电容值相对基准电容值的差值与基准振荡电容值的比值、当前频率值相对基准频率值的差值与基准频率值的比值或者当前计数值相对基准计数值的差值与基准计数值的比值时，此时第二预设参数范围对应为差值范围、比值范围，第二预设参数范围的下限值大于第一预设参数范围的下限值。另外，在本申请的其他实施例中，第二预设参数范围的上限值不设限，也即当前电容值大于a即落入第二预设参数范围内。当第一参数信息为当前频率值、当前计数值、当前频率值与基准频率值的比值或者当前计数值与基准计数值的比值时，第二预设参数范围对应为频率值范围、计数值范围或者比值范围，第二预设参数范围的上限值要小于第一预设参数范围的上限值，第二预设参数范围的下限值大于或等于第一预设参数范围的下限值，例如第一参数信息为当前计数值时，第二预设参数范围为[m,M)，例如M为950，第一预设参数范围为[n,N),例如N为970，其中，M小于N，m大于或等于n，M、m、N、n为正整数。另外，在本申请的其他实施例中，第二预设参数范围的下限值不设限，也即当前频率值或者当前计数值小于M即落入第二预设参数范围内。
进一步的，当电子烟处于抽吸状态时，为了判断第一参数信息是否位于第二预设参数范围内，本实施例童锁控制电路200还包括第二参数判断单元211，第二参数判断单元211与状态检测单元150连接，状态检测单元150本身就知道第一参数信息，也即状态检测单元150本身就知道当前电容值、当前频率值或者当前计数值等，从而状态检测单元150输出第一参数信息给第二参数判断单元211，第二参数判断单元211用于接收第一参数信息并判断第一参数信息是否位于第二预设参数范围内，进而可以区分用户是正常抽吸还是进入锁定状态的抽吸，经过这样区分，可以降低用户正常抽吸时误判断进入童锁锁定状态的概率。
请结合参见图16、图17和图22，本申请实施例提供一种电子烟的童锁控制方法，包括以下步骤：
S11：接收第一参数信息；
其中，第二参数判断单元211与状态检测单元150连接，状态检测单元150产生第一参数信息，并输出第一参数信息，第二参数判断单元211接收第一参数信息。
在本实施例中，状态检测单元150本身可以识别电子烟是否处于抽吸状态或者吹气状态，当用户抽吸电子烟时，状态检测单元150通过气流传感器140识别电子烟处于抽吸状态，此时状态检测单元150判断第一参数信息位于第一预设参数范围内，状态检测单元150输出抽吸信号，当用户吹气时，状态检测单元150通过气流传感器140识别电子烟处于吹气状态，此时状态检测单元150输出吹气信号，当电子烟既不被抽吸，也不被吹气时，此时状态检测单元150识别电子烟处于未吸吹状态，状态检测单元150输出未吸吹信号。童锁控制电路200接收状态检测单元150的输出信号，从而获取电子烟的状态。当状态检测单元150由输出未吸吹信号转为输出抽吸信号或者吹气信号时，童锁控制电路200获取电子烟由未吸吹状态转为抽吸状态或者吹气状态。在本实施例中，未抽吸状态包括未吸吹状态、吹气状态。
S12:判断第一参数信息是否位于第二预设参数范围内，其中，所述第二预设参数范围位 于第一预设参数范围内，所述第一预设参数范围用于判断电子烟是否处于抽吸状态；
S13：若判断结果为是，则触发进行第二计时并触发进行第二计数；
其中，第二参数判断单元211在接收到第一参数信息后，第二参数判断单元211判断第一参数信息是否位于第二预设参数范围内，第二预设参数范围为预先计算获得，或者预先存储在第二参数判断单元211中。其中，童锁控制电路200包括第二计时单元216和第二计数单元215，第二计时单元216与第二参数判断单元211电连接，第二计数单元215与第二参数判断单元211电连接，若第二参数判断单元211的判断结果为是，则第二参数判断单元211输出参数有效信号，第二计时单元216被触发开始计时，第二计时单元216从0开始计时，第二计数单元215被触发开始计数，并将此次也进行计数，也即此时第二计数单元215的计数为1；若第二参数判断单元211的判断结果为否，则第二参数判断单元211输出参数无效信号，第二计时单元216维持原先的状态，第二计数单元215维持原先的状态。在本实施例中，当第二计时单元216被触发开始计时后，第二计时单元216会一直在计时，直到第二计时单元216被复位置零，此后第二计时单元216停止计时。
当第二计时单元216被触发计时、第二计数单元215被触发计数后，当第二参数判断单元211又接收到第一参数信息，并又一次判断第一参数信息位于第二预设参数范围内，也即又输出参数有效信号，则第二计数单元215的第二计数加1，此时第二计数为2，同时，第二计时单元216在持续进行第二计时。
S14：判断在第二预设时长内第二计数是否大于或等于第二预设数量，其中，第二预设数量大于或等于2；
其中，童锁控制电路200还包括第二计时计数判断单元217，第二计时计数判断单元217分别与第二计数单元215、第二计时单元216连接，当第二计时计数判断单元217判断第二计时单元216的计时时长在第二预设时长内，且第二计数单元215的第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号。在本实施例中，第二预设时长一般小于或等于5s，第二预设时长例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第二预设数量为大于或等于2的整数，例如为2、3、4、5、6等，较佳为3，第二预设数量一般小于或等于6次，方便用户操作。例如，第二预设时长为2秒，第二预设数量为3，则在2秒内第二计数大于或等于3，第二计时计数判断单元217输出童锁锁定信号。
在本实施例中，第二计时计数判断单元217与第二计时单元216、第二计数单元215实时电连接，当第二计时计数判断单元217获取第二计数到达第二预设数量且第二计时单元216未到达第二预设时长时，第二计时计数判断单元217输出童锁锁定信号，或者第二计时计数判断单元217等第二计时单元216计时时长到达第二预设时长时才输出童锁锁定信号。在本申请的其他实施例中，第二计时计数判断单元217与第二计时单元216、第二计数单元215连接，当第二计时单元216到达第二预设时长时第二计时单元216输出信号给第二计时计数判断单元217，第二计时计数判断单元217获取此时第二计数单元215的第二计数，然后判断第二计数是否大于或等于第二预设数量，若第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号，若第二计数小于第二预设数量，则第二计时计数判断单元217维持原来的信号输出。
S15：若判断结果为是，则控制电子烟进入锁定状态，在锁定状态所述功率MOS管M1保持断开截止。
其中，童锁控制电路200还包括童锁控制单元240，童锁控制单元240与第二计时计数判断单元217电连接。若第二计时计数判断单元217的判断结果为是，也即在第二预设时长内第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁锁定信号给童锁控制单元240，童锁控制单元240控制电子烟进入锁定状态，在锁定状态功率MOS管M保持断开，在本实施例中童锁控制单元240持续输出高电平信号给功率MOS管M，功率MOS管M保持截止。在本实施例中，童锁控制单元240包括触发器和开关控制单元，触发器用于对童锁锁定信号、后续的童锁解锁信号进行保持，触发器例如为SR触发器等，开关控制单 元分别与触发器、状态检测单元150电连接，开关控制单元例如为与门、与非门、或门、或非门等，例如，开关控制单元包括与非门，与非门的两个输入端分别与触发器的输出端、状态检测单元150的一个输出端连接，童锁锁定信号使触发器的输出保持为低电平，从而经过与非门后保持为高电平(此时状态检测单元150输出抽吸信号，抽吸信号例如为高电平)，功率MOS管M保持截止；童锁解锁信号使触发器的输出保持为高电平，从而与非门的输出受状态检测单元150的输出影响，当状态检测单元150判断用户抽吸电子烟时，状态检测单元150输出抽吸信号给与非门，抽吸信号为高电平，此时开关控制单元控制功率MOS管M持续导通或者间断导通(例如PWM、PFM控制方式)。若第二计时计数判断单元217的判断结果为否，也即在第二预设时长内第二计数小于第二预设数量，则维持电子烟原先的童锁状态，且第二计数置0，第二计时复位置零。
在本实施例中，电子烟的童锁状态分为锁定状态和解锁状态，其中，锁定状态即对应童锁保护功能，当电子烟处于锁定状态时用户抽吸电子烟，童锁控制单元240继续控制功率MOS管M1保持断开截止，从而发热元件130不会加热，进而烟油不会雾化以供用户抽吸，也即即使用户抽吸电子烟也不会出现烟雾。解锁状态对应解除童锁保护功能，此时烟油是否雾化受是否抽吸的控制，当用户抽吸电子烟时，童锁控制单元240控制功率MOS管M1持续导通或者间断导通，间断导通是指童锁控制单元240通过PWM方式、PFM方式输出方波信号，通过调整方波信号的占空比以用于控制输出功率、输出电压。
在本实施例中，通过接收第一参数信息；判断第一参数信息是否位于第二预设参数范围内，若判断结果为是，则触发进行第二计时并触发进行第二计数；判断在第二预设时长内第二计数是否大于或等于第二预设数量，若判断结果为是，则控制电子烟进入锁定状态。本申请实施例通过第一参数信息、第二预设参数范围对抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，将第一参数信息位于第二预设参数范围的抽吸次数分辨为气压更小的抽吸状态(重吸)，并进行第二计数，并且在第二预设时长内第二计数大于或等于第二预设数量才使电子烟进入锁定状态，通过这样设置，电子烟可以进一步分辨用户是正常抽吸电子烟，还是想要通过抽吸电子烟触发进入锁定状态，电子烟不容易混淆两者，可以降低用户正常抽吸电子烟时被误触发进入锁定状态的几率，可以减少用户的使用困扰。而且，通过在第二预设时长内第二计数大于或等于第二预设数量，可以实现电子烟进入锁定状态，本实施例的电子烟在锁定保护后，可以防止儿童拿起电子烟模仿成人抽吸动作导致电子烟产品开始雾化工作，提升电子烟的使用安全性。再有，本实施例利用现有的状态检测单元150、气流传感器140就可以得到第一参数信息，不需要对电子烟进行大改，不需要增加硬件成本或者增加的硬件成本很小，从而缩减了电子烟进行锁定保护的硬件成本，解决现有技术中电子烟锁定成本较高的技术问题。
在本实施例中，童锁控制方法还包括：再次获取第一参数信息位于第二预设参数范围内的信息，第二计数加1。
具体而言，在第二计数单元215触发第二计数和第二计时单元216触发第二计时后，第二计时单元216和第二计数单元215未停止工作，当电子烟转为未抽吸状态，其后，当用户再次抽吸电子烟，再次实时获取第一参数信息，若第二计数单元215再次获取第一参数信息位于第二预设参数范围内的信息，也即第二计数单元215又收到参数有效信号，则第二计数单元215在原来第二计数的基础上加1，例如原来第二计数单元215的计数值为1，再次获取第一参数信息位于第二预设参数范围内的信息，则第二计数单元215的第二计数加1，也即第二计数变为2，同时，第二计时单元216在触发第二计时后，第二计时单元216一直在计时；若此次第二计数单元215没有获取第一参数信息位于第二预设参数范围内的信息，也即第二计数单元215没有收到参数有效信号，则第二计数保持不变，此时第二计时单元216也在计时。
在本实施例中，童锁控制方法还包括：若第二计时达到第二预设时长，则第二计数置零，且第二计时复位置零。
其中，不论第二计时计数判断单元217的判断结果为是还是不为是，只要第二计时单元 216的计时时长达到第二预设时长，则第二计时单元216复位置零，同时第二计时单元216发送信号给第二计数单元215，第二计数单元215进行置零，也即此时第二计时单元216停止计时，计时时长置零，第二计时单元216、第二计数单元215恢复初始状态，方便后面信号的检测。在本实施例中，第二计时计数判断单元217在第二计时单元216、第二计数单元215复位置零前已完成判断。
在本实施例中，童锁控制方法还包括：若第二计时小于第二预设时长且第二计数达到第二预设数量，则第二计数置零，且第二计时复位置零。
其中，若第二计时计数判断单元217获取第二计数达到第二预设数量，且第二计时单元216计时时长小于第二预设时长，则第二计时计数判断单元217输出信号给第二计时单元216、第二计数单元215，第二计时单元216进行复位置零，第二计数单元215置零，该信号可以与童锁锁定信号一样，也可以是不同的信号。
请参见图22，在本实施例中，步骤接收第一参数信息具体包括：
接收状态检测单元150输出的第一参数信息。
其中，状态检测单元150本身可以得到第一参数信息，第二参数判断单元211通过状态检测单元150接收第一参数信息。本实施例充分利用现有电子烟中的气流传感器140、状态检测单元150，只需要增设第二参数判断单元211，第二参数判断单元211所要实现的功能既可以通过软体实现，也可以通过硬件实现，也可以通过软体和硬件结合实现，从而不需要增加新的硬件或者增加新的硬件较少，可以实现不增加成本或者增加少量成本就可以极大的降低电子烟误进入锁定状态的问题，提升了用户的使用便利性。
在应用上述的方案进行实际测试过程中发明人发现：由于空气中气流的扰动，可能会导致处于抽吸状态时瞬间的气压下降，导致第一参数信息到达第二预设参数范围，这个瞬间的气压下降持续时间很短，一般偶尔的一次，造成第二计数单元215误计数，可能误触发电子烟进入锁定状态，给用户的使用造成困扰。为了解决该问题，请结合参阅图18和图22，步骤触发进行第二计数具体包括：
S131:触发进行第三计时并触发进行第三计数；
其中，童锁控制电路200还包括第三计时单元212和第三计数单元213，第三计时单元212、第三计数单元213均与第二参数判断单元211连接，当第三计时单元212、第三计数单元213获取第一参数信息位于第二预设参数范围内时，也即第三计时单元212接收到参数有效信号时，第三计时单元212开始第三计时，第三计时单元212一直计时，直到进行复位置零，此后第三计时单元212停止计时；第三计数单元213接收到参数有效信号时，第三计数单元213开始第三计数，且此次也进行第三计数，此时第三计数为1。
S132:判断在第三预设时长内第三计数是否大于或等于第三预设数量；
其中，童锁控制电路200还包括第三计时计数判断单元214，第三计时计数判断单元214分别与第三计数单元213、第三计时单元212连接，当第三计时计数判断单元214判断第三计时单元212的计时时长在第三预设时长内，且第三计数单元213的第三计数大于或等于第三预设数量，则第三计时计数判断单元214输出第一计数信号。在本实施例中，第三预设时长一般为30ms-150ms，第三预设时长例如为30ms、40ms、50ms、60ms、70ms、80ms、90ms、100ms、110ms、120ms、130ms、140ms、150ms等，较佳为60ms-100ms。在本实施例中，第三预设数量为大于或等于2的整数，例如为2、3等。在本实施例中，第三预设数量大于或等于2，例如为2、3、4、5、6等。
在本实施例中，第三计时计数判断单元214与第三计时单元212、第三计数单元213实时电连接，当第三计时计数判断单元214获取第三计数到达第三预设数量且第三计时未到达第三预设时长时，第三计时计数判断单元214输出第一计数信号，或者第三计时计数判断单元214等第三计时到达第三预设时长时才输出第一计数信号。在本申请的其他实施例中，第三计时计数判断单元214与第三计时单元212、第三计数单元213连接，当第三计时单元212到达第三预设时长时第三计时单元212输出信号给第三计时计数判断单元214，第三计时计数判断单元214获取此时第三计数单元213的第三计数，然后判断第三计数是否大于或等于 第三预设数量，若第三计数大于或等于第三预设数量，则第三计时计数判断单元214输出第一计数信号，若第三计数小于第三预设数量，则第三计时复位置零，第三计数置零。
S133:若判断结果为是，则触发进行第二计数。
其中，第三计时计数判断单元214与第二计时单元216、第二计数单元215连接。若第三计时计数判断单元214的判断结果为是，则第二计时单元216接收到第一计数信号，第二计时单元216被触发开始计时，第二计时从0开始计时；第二计数单元215接收到第一计数信号，第二计数单元215被触发开始计数，此时第二计数单元215对本次也进行计数，也即此时第二计数为1。
在本实施例中，当此前第二计数单元215没有被触发开始计数，第二计时单元216没有被触发开始计时，若第三计时计数判断单元214的判断结果为否，也即第三计时计数判断单元214不输出第一计数信号，第二计数单元215维持原来不进行计数，第二计时单元216维持原来不进行计时；当此前第二计数单元215已被触发开始计数(也即第二计数至少为1)，第二计时单元216已被触发计时，若第三计时计数判断单元214的判断结果为否，则第二计数维持原来的计数，第二计数不增加，第二计时继续计时。
在本实施例中，当空气气流串扰导致电子烟气流通道内气压短时间变化时，由于气压降低的时长很短，从而不会符合在第三预设时长内第三计数大于或等于第三预设数量的条件，从而第二计数不会变化，从而不会将空气气流串扰误判为用户想要进入童锁保护的情况，可以防止电子烟误进入锁定状态，可以防止对用户的使用造成困扰，本实施例可以避免这种情况发生，提升了用户的使用体验。
在本实施例中，在整个第三预设时长电子烟处于抽吸状态，在第三预设时长的部分时长或者整个时长均属于重吸，则第二计时单元216进行计数。
为了判断电子烟是否处于抽吸状态，请结合参见图19和图22，在本实施例中，童锁控制方法还包括:
S171:接收第一参数信息；
S172:判断第一参数信息是否位于第一预设参数范围内；
S173：若判断结果为是，则输出电子烟由未抽吸状态转为抽吸状态的信息。
其中，状态检测单元150包括第一参数生成单元、第一参数判断单元，第一参数生成单元分别与第一参数判断单元、第二参数判断单元211连接，第一参数生成单元生成第一参数信息后，第一参数判断单元接收第一参数信息，第一参数判断单元判断第一参数信息是否位于第一预设参数范围内，若判断结果为是，则第一参数判断单元输出电子烟由未抽吸状态转为抽吸状态的信息，也即输出抽吸信号，若判断结果为否，则第一参数判断单元维持原来的信号输出，例如输出未吸吹信号、吹气信号。进一步的，还可以要求连续多次判断为是，才输出抽吸信号，这样有利于降低气流串扰误触发的几率。在本实施例中，第一参数判断单元、第二参数判断单元211可以为同一个参数判断单元，也可以为不同的参数判断单元。
在本实施例中，为了降低电子烟处于未抽吸状态时的功耗，步骤接收第一参数信息具体包括：
获取电子烟由未抽吸状态转为抽吸状态的信息；
触发接收第一参数信息。
其中，第二参数判断单元211与状态检测单元150连接，第二参数判断单元211在未收到抽吸信号前不工作，当第二参数判断单元211在接收到抽吸信号后，第二参数判断单元211被触发开始工作，此时第二参数判断单元211接收第一参数信息。这样设置，有利于降低电子烟的功耗。
另外，在本实施例中，请结合参阅图20和图22，在步骤触发进行第二计数之后还包括：
S161:获取电子烟由抽吸状态进入未抽吸状态的信息；
S162:触发第五计时且对第二计数进行锁定；
S163:判断第五计时是否大于或等于第五预设时长；
S164:若判断结果为是，则解除对第二计数的锁定。
本实施例还对两次抽吸状态(包含两次重吸)之间的间隔时长进行规定，防止抽吸状态时气流抖动、串扰等而导致误第二计数。具体而言，在本实施例中，童锁控制电路200包括第五计时单元221和第五时长判断单元222，第五计时单元221分别与第一参数判断单元、第三计时计数判断单元214连接，第五时长判断单元222分别与第五计时单元221、第二计数单元215电连接，第二计数单元215还与第一参数判断单元电连接。当第三计时计数判断单元214输出第一计数信号后，第五计时单元221收到第一计数信号后又获取电子烟由抽吸状态进入未抽吸状态的信息，第五计时单元221被触发开始计时，同时第二计数单元215也在接收第一计数信号后又获取电子烟由抽吸状态进入未抽吸状态的信息，第二计数单元215被锁定，也即进入计数锁定状态，第二计数单元215被锁定后即使再接收到第一计数信号也不会进行计数增加，也即在锁定状态第二计数单元215保持原来的计数值，不会增加计数值，只有被解除锁定后处于计数解锁状态第二计数单元215收到第一计数信号才会计数加一。在本实施例中，当第五计时单元221开始第五计时后，第五计时单元221一直在计时(即使由未抽吸状态转为抽吸状态也在计时)，第五时长判断单元222判断第五计时单元221的计时时长是否大于或等于第五预设时长，当第五时长判断单元222判断第五计时单元221计时到达第五预设时长，第五计时单元221会停止计时并置零，也即第五计时单元221复位置零，同时，第五时长判断元输出计数解锁信号给第二计数单元215，第二计数单元215被解除对计数的锁定，第二计数单元215进入计数解锁状态，而且第三计时单元212、第三计数单元213、第二计时单元216也复位置零，此后第二计数单元215再次获取第一计数信号，第二计数单元215可以执行计数加一动作，也即第二计数在原来的基础上加一。在此实施例中，当第五计时单元221没有收到第一计数信号，或者第五计时单元221没有获取电子烟由抽吸状态进入未抽吸状态的信息，第五计时单元221也不会触发开始计时。
在本实施例中，在步骤触发进行第二计数之后还包括：判断第一参数信息位于第二预设参数范围内持续的时长是否大于或等于第七预设时长，若判断结果为是，则第二计数、第二计时均复位置零。本实施例中对重吸持续的时长进行判断，若重吸持续的时长大于或等于第七预设时长，则第二计数、第二计时均复位置零，第二计数为0，第二计时停止计时并置零，这样设置可以防止用户比较长时间抽吸后误动作进入童锁锁定状态，符合用户的使用预期。在本实施例中，第七预设时长大于或等于400ms，例如为400ms、450ms、500ms、600ms等。
在本实施例中，电子烟进入童锁锁定状态后，用户没法正常抽吸电子烟，当用户需要使用电子烟时，此时需要对电子烟进行解锁，以下描述电子烟如何进行解锁，以下描述的仅是一种进入童锁解锁状态的方式，本领域的技术人员还可以通过其他常规的方式使电子烟进入童锁解锁状态。另外，在本申请的其他实施例中，解锁方式可以与加锁方式一样，可以参见前面的描述，在此不再赘述。
请结合参阅图21和图22，在本实施例中，童锁控制方法还包括：

其中，童锁控制电路200包括第四参数判断单元231，第四参数判断单元231用于接收第一参数信息，其中，第四参数判断单元231与第二参数判断单元211可以为不同的判断单元，也可以为同一参数判断单元。
在本实施例中，当处于吹气状态时，气流通道中气压较大，会高于未吸吹状态的气压，也即当前气压值会大于基准气压值，气流传感器140的电容的两个电极的间距相对未吸吹状态时要大，从而当前电容值会比未吸吹状态时小，当前频率值会比未吸吹状态时大，当前计数值会大于基准计数值。
S22:判断第一参数信息是否位于第四预设参数范围内，所述第四预设参数范围用于判断电子烟是否处于吹气状态；

其中，第四参数判断单元231在接收到第一参数信息后，第四参数判断单元231判断第一参数信息是否位于第四预设参数范围内，第四预设参数范围为预先计算获得，或者预先存储在第四参数判断单元231中。
当第一参数信息为当前电容值时，此时第四预设参数范围对应为电容值范围，第四预设参数范围的上限值会小于第一预设参数范围对应的下限值，第四预设参数范围的下限值可以不设限，也可以根据需要设限；当第一参数信息为当前频率值或者当前计数值时，此时第四预设参数范围对应为频率值范围或者计数值范围，第四预设参数范围的下限值会大于第一预设参数范围对应的上限值，第四预设参数范围的上限值可以不设限，也可以根据需要设限；当第一参数为当前电容值与基准电容值的比值、当前频率值与基准频率值的比值、当前计数值与基准计数值的比值、当前电容值与基准电容值的差值、当前频率值与基准频率值的差值、当前计数值与基准计数值的差值、当前电容值相对基准电容值的差值与基准振荡电容值的比值、当前频率值相对基准频率值的差值与基准频率值的比值或者当前计数值相对基准计数值的差值与基准计数值的比值时，此时第四预设参数范围对应为差值范围、比值范围。

在本实施例中，当第四计时单元232被触发计时、第四计数单元233被触发计数后，当第四参数判断单元231又接收到第一参数信息，并又一次判断第一参数信息位于第四预设参数范围内，则第四计数单元233的第四计数加1，此时第四计数为2，同时，第四计时单元232在持续进行第四计时。

其中，童锁控制电路200还包括第四计时计数判断单元234，第四计时计数判断单元234分别与第四计数单元233、第四计时单元232电连接，当第四计时计数判断单元234判断第四计时单元232的计时时长在第四预设时长内，且第四计数单元233计数大于或等于第四预设数量，第四计时计数判断单元234输出童锁解锁信号。在本实施例中，第四预设时长一般小于或等于5s，例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第四预设数量大于或等于2，例如为2、3、4、5、6等，较佳为3，第四预设数量一般小于或等于6次，方便用户操作。
在本实施例中，第四计时计数判断单元234与第四计时单元232、第四计数单元233实时连接，当第四计时计数判断单元234获取第四计数单元233到达第四预设数量且第四计时单元232未到达第四预设时长时，第四计时计数判断单元234输出童锁解锁信号，或者第四计时计数判断单元234等第四计时单元232计时时长到达第四预设时长时才输出童锁解锁信号。在本申请的其他实施例中，第四计时计数判断单元234与第四计时单元232、第四计数单元233连接，当第四计时单元232到达第四预设时长时第四计时单元232输出信号给第四计时计数判断单元234，第四计时计数判断获取此时第四计数单元233的计数，然后判断第四计数是否大于或等于第四预设数量，若大于或等于第四预设数量，则输出童锁解锁信号，若小于第四预设数量，则维持原来的信号输出。
S24:若判断结果为是，则控制电子烟进入解锁状态，其中，在解锁状态所述电子烟处于抽吸状态时所述功率MOS管M1持续导通或者间断导通。
其中，若第四计时计数判断单元234判断的结果为是，也即在第四预设时长内计数的数量大于或等于第四预设数量，则第四计时计数判断单元234输出童锁解锁信号给童锁控制单元240，童锁控制单元240控制电子烟进入解锁状态，在解锁状态电子烟处于抽吸状态时功率MOS管M1持续导通或者间断导通，也即此时功率MOS管M1受用户是否抽吸的控制， 在本实施例中电子烟处于抽吸状态时童锁控制单元240持续输出低电平信号或者间断输出低电平信号给功率MOS管M1，功率MOS管M1持续导通或者间断导通，当功率MOS管M1导通时，发热元件130加热以雾化烟油，从而雾化后的烟油可供被用户抽吸。
在本实施例中，通过对吹气进行计时和计数实现解锁，在没有增加蓝牙/NFC等设计以及机械结构的同时，实现了有效的解锁效果，从而缩减了电子烟的进行解锁的硬件成本，解决现有技术中电子烟解锁成本较高的技术问题。而且，本申请的解锁方式不容易被儿童察觉，电子烟在锁定后不容易被儿童解锁，有利于提升电子烟的安全性。另外，在本申请的其他实施例中，同判断抽吸状态一样，也可以通过当前计数值来判断是否进行吹气。
在本实施例中，童锁控制方法还包括：再次获取第一参数信息位于第四预设参数范围内的信息，第四计数加1。
具体而言，在第四计数单元233触发第四计数和第四计时单元232触发第四计时后，第四计时单元232和第四计数单元233未停止工作，第四计时单元232、第四计数单元233再次(再次是指第四计数单元233中第四计数的数值至少为1)获取第一参数信息位于第四预设参数范围内的信息，则第四计数单元233在原来计数的基础上加1，例如原来第四计数单元233的计数值为1，再次获取第一参数信息位于第四预设参数范围内的信息，也即接收到由未吸吹状态转为吹气状态的信息，则第四计数单元233的计数加1，也即计数值变为2；第四计时单元232继续工作持续计时，也即第四计时单元232在触发计时后，只要不收到停止计时或者复位的信号，则第四计时单元232一直在计时。
在本实施例中，童锁控制方法还包括：若第四计时单元232的计时时长达到第四预设时长，则第四计数置零，且第四计时单元232复位置零。
其中，不论第四计时计数判断单元234的判断结果为是还是否，只要第四计时单元232的计时时长达到第四预设时长，则第四计时单元232复位置零，同时第四计时单元232发送信号给第四计数单元233，第四计数单元233进行置零，也即此时第四计时单元232停止计时，第四计数单元233停止计数，而且，计时时长置零，第四计数均置零，第四计时单元232、第四计数单元233恢复初始状态，方便后面的检测。
在本实施例中，童锁控制方法还包括：若第四计时单元232的计时时长小于第四预设时长且第四计数达到第四预设参数范围，则第四计数置零，且第四计时单元232复位置零。
其中，若第四计时计数判断单元234获取第四计数单元233的第四计数达到第四预设参数范围，且第四计时单元232计时时长小于第四预设时长，则第四计时计数判断单元234输出信号给第四计时单元232、第四计数单元233，第四计时单元232复位置零，第四计数单元233进行置零，该信号可以与童锁解锁信号一样，也可以是不同的信号。

第四实施例
本申请第四实施例提供一种电子烟，请结合参见图24和图29，电子烟包括电池110、童锁控制电路200、发热元件130、气流传感器140、功率MOS管M1等，童锁控制电路200包括状态检测单元150。童锁控制电路200分别与电池110、气流传感器140、功率MOS管 M1等电连接。在本实施例中，电池110例如为锂电池、镍镉电池、镍氢电池等可充电电池，电池110也可以为不可充电电池；状态检测单元150与气流传感器140电连接，状态检测单元150用于判断电子烟是否被抽吸和/或被吹气，并输出对应信号，状态检测单元150的一个具体实现方式可参见本领域的在先申请，或者为本领域技术人员知晓的其他常规的状态检测单元。在本实施例中气流传感器140为电容式气流传感器140，例如为电容式MEMS传感器或电容式咪头等，气流传感器140位于电子烟的气流通道内，气流传感器140包括电容，状态检测单元150通过电容的电容值等的变化判断电子烟是否处于抽吸状态、吹气状态、未吸吹状态(对应用户未使用时的状态)。童锁控制电路200与功率MOS管M1的控制端电连接，童锁控制电路200用于控制功率MOS管M1是否导通，功率MOS管M1与发热元件130串联形成串联支路，串联支路的一端经由电源供电端BAT与电池110的正极电连接，串联支路的另一端经由电源接地端GND与电池110的负极电连接。在本实施例中以功率MOS管M1为PMOS管为例进行说明，当然，功率MOS管M1也可以为NMOS管。在本实施例中，功率MOS管M1、童锁控制电路200可以位于同一个芯片，该芯片一般称为系统控制芯片。但本申请不限于此，在本申请的其他实施例中，功率MOS管M1、童锁控制电路200可以位于不同的芯片上。在本实施例中，发热元件130例如为发热丝、加热丝、包含发热丝或者加热丝的陶瓷座、或者其他常规的发热元件130。在本实施例中，当童锁控制电路200输出低电平控制功率MOS管M1导通时发热元件130加热以使烟油雾化，当童锁控制电路200输出高电平控制功率MOS管M1断开截止时发热元件130停止加热。
在本实施例中，状态检测单元150与气流传感器140电连接；当用户抽吸电子烟或者向电子烟吹气时，气流传感器140的电容的两个电极片之间气压值相对未吸吹状态(未使用时)会改变，导致两个电极片之间的距离会随之改变，进而引起气流传感器140的电容值改变，状态检测单元150将电容值改变转换为频率值改变、计数值改变，状态检测单元150输出对应的信号，从而电子烟可以判断是否被抽吸处于抽吸状态、被吹气处于吹气状态或者处于未吸吹状态。
为了区分正常抽吸和触发进入锁定状态的抽吸，以降低正常抽吸时被误触发进入锁定状态的概率，本申请的发明人经过大量实验后提出以下方案：对电子烟的抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，气压较小(用户抽吸的吸力较小)的抽吸状态一般对应用户正常的抽吸，气压更小(用户抽吸的吸力较大)的抽吸状态对应用户想要进入锁定状态的抽吸，不管是处于气压较小的抽吸状态，还是处于气压较大的抽吸状态，电子烟均会判断为抽吸状态，本申请通过第一参数信息是否位于第二预设参数范围内判断是否为气压更小的抽吸状态。
具体而言，第一参数信息表征电子烟气流通道内的气压状况，气压状况例如为气压大小、气压的变化状况等，第一参数信息与气流通道内的气压呈对应关系，本实施例设计当第一参数信息位于第二预设参数范围内时代表此时处于气压更小的抽吸状态，当第一参数信息位于第二预设参数范围之外且位于第一预设参数范围之内时代表气压较小的抽吸状态，其中，第二预设参数范围位于第一预设参数范围内，也即只要第一参数信息位于第二预设参数范围内，第一参数信息必然位于第一预设参数范围内，表示此时电子烟处于抽吸状态且是重吸，当第一参数信息位于第一预设参数范围内时，第一参数信息可能位于第二预设参数范围内(重吸)，也可能不位于第二预设参数范围内(正常抽吸)。
在本实施例中，第一参数信息包括当前电容值、当前频率值、当前计数值、当前电容值与基准电容值的比值、当前频率值与基准频率值的比值、当前计数值与基准计数值的比值、当前电容值与基准电容值的差值、当前频率值与基准频率值的差值、当前计数值与基准计数值的差值、当前电容值相对基准电容值的差值与基准振荡电容值的比值、当前频率值相对基准频率值的差值与基准频率值的比值或者当前计数值相对基准计数值的差值与基准计数值的比值等，或者当前电容值、当前频率值或者当前计数值的变形。当电子烟未被抽吸也未被吹气时，也即电子烟处于未吸吹状态时，此时电容的电极片未变形，此时的电子烟气流通道内的当前气压值为大气压，即为基准气压值，当前电容值即为基准电容值，此时基准电容值是 采集获得或者转换获得，此时对应的当前频率值即为基准频率值，此时预设计数时长内的振荡周期数为当前计数值，也为基准计数值；另外，基准气压值、基准电容值、基准频率值、基准计数值也可以预设。当用户轻吸导致电子烟气流通道内的当前气压值较小时，此时当前气压值小于基准气压值，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变小，当前电容值会较大，当前电容值与基准电容值的比值会较大，当前频率值会较小，预设计数时长内的振荡周期数会较小，当前计数值会较小，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会较小，对应差值会较大，对应差值与对应基准值的比值会较大；当用户重吸导致电子烟气流通道内的当前气压值更小时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变更小，当前电容值会更大，当前电容值与基准电容值的比值会更大，当前频率值会更小，预设计数时长内的振荡周期数会更小，当前计数值会更小，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会更小，对应差值会更大，对应差值与对应基准值的比值会更大。当用户吹气导致电子烟气流通道内的当前气压值相对未吹吸状态变大时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变大，气流传感器140的当前电容值会变小，当前频率值会变大，当前计数值会比基准计数值大。
当气流通道内当前气压值更小时气流传感器140的电容变形更大，电容的两个电极片之间的距离更小，从而其当前电容值会更大，当前电容值与基准电容值的比值会更大，当前计数值会更小，当前频率值会更小，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会更小，对应差值会更大，对应差值与对应基准值的比值会更大；当气流通道内当前气压值较小时气流传感器140的电容变形较大，电容的两个电极片之间的距离较小，从而其电容值会较大，当前电容值与基准电容值的比值会较大，当前计数值会较小，当前频率值会较小，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会较小，对应差值会较大，对应差值与对应基准值的比值会较大。因而当前电容值、当前计数值、当前频率值等均与气流通道内的当前气压值呈比例关系。
由于本申请设计成用户重吸才进入童锁锁定状态，当第一参数信息为当前电容值时，第二预设参数范围对应为电容值范围，第二预设参数范围的下限值要大于第一预设参数范围的下限值，第二预设参数范围的上限值小于或等于第一预设参数范围的上限值，例如第二预设参数范围为(a，A]，第一预设参数范围(b，B],其中，a大于b，A小于或等于B，A、a、B、b为正数。当所述第一参数信息为当前电容值与基准电容值的差值、当前频率值与基准频率值的差值、当前计数值与基准计数值的差值、当前电容值相对基准电容值的差值与基准振荡电容值的比值、当前频率值相对基准频率值的差值与基准频率值的比值或者当前计数值相对基准计数值的差值与基准计数值的比值时，此时第二预设参数范围对应为差值范围、比值范围，第二预设参数范围的下限值大于第一预设参数范围的下限值。另外，在本申请的其他实施例中，第二预设参数范围的上限值不设限，也即当前电容值大于a即落入第二预设参数范围内。当第一参数信息为当前频率值、当前计数值、当前频率值与基准频率值的比值或者当前计数值与基准计数值的比值时，第二预设参数范围对应为频率值范围、计数值范围或者比值范围，第二预设参数范围的上限值要小于第一预设参数范围的上限值，第二预设参数范围的下限值大于或等于第一预设参数范围的下限值，例如第一参数信息为当前计数值时，第二预设参数范围为[m,M)，例如M为950，第一预设参数范围为[n,N),例如N为970，其中，M小于N，m大于或等于n，M、m、N、n为正整数。另外，在本申请的其他实施例中，第二预设参数范围的下限值不设限，也即当前频率值或者当前计数值小于M即落入第二预设参数范围内。
进一步的，当电子烟处于抽吸状态时，为了判断第一参数信息是否位于第二预设参数范围内，本实施例童锁控制电路200还包括第二参数判断单元211，第二参数判断单元211与状态检测单元150连接，状态检测单元150知道第一参数信息，状态检测单元150本身就知道当前电容值、当前频率值或者当前计数值，从而状态检测单元150输出第一参数信息给第二参数判断单元211，第二参数判断单元211用于接收第一参数信息并判断第一参数信息是 否位于第二预设参数范围内，进而可以区分用户是正常抽吸还是进入锁定状态的抽吸，经过这样区分，可以降低用户正常抽吸时误判断进入童锁锁定状态的概率。

S11：接收第一参数信息，其中，所述第一参数信息用于表征电子烟气流通道内的气压大小
其中，第二参数判断单元211与状态检测单元150连接，状态检测单元150产生第一参数信息，并输出第一参数信息，第二参数判断单元211接收第一参数信息。
在本实施例中，状态检测单元150本身可以识别电子烟是否处于抽吸状态或者吹气状态，当用户抽吸电子烟时，状态检测单元150通过气流传感器140识别电子烟处于抽吸状态，此时状态检测单元150判断第一参数信息位于第一预设参数范围内，状态检测单元150输出抽吸信号，当用户吹气时，状态检测单元150通过气流传感器140识别电子烟处于吹气状态，此时状态检测单元150输出吹气信号，当电子烟既不被抽吸，也不被吹气时，此时状态检测单元150识别电子烟处于未吸吹状态，状态检测单元150输出未吸吹信号。童锁控制电路200接收状态检测单元150的输出信号，从而获取电子烟的状态。当状态检测单元150由输出未吸吹信号转为输出抽吸信号或者吹气信号时，童锁控制电路200获取电子烟由未吸吹状态转为抽吸状态或者吹气状态。在本实施例中，未抽吸状态包括未吸吹状态、吹气状态。
S12:判断第一参数信息是否位于第二预设参数范围内，其中，所述第二预设参数范围位于第一预设参数范围内，所述第一预设参数范围用于判断电子烟是否处于抽吸状态；
S13：若判断结果为是，则控制电子烟进入锁定状态，在锁定状态所述功率MOS管保持断开截止。
其中，第二参数判断单元211在接收到第一参数信息后，第二参数判断单元211判断第一参数信息是否位于第二预设参数范围内，第二预设参数范围为预先计算获得，或者预先存储在第二参数判断单元211中。
其中，童锁控制电路200还包括童锁控制单元240，童锁控制单元240与第二参数判断单元211电连接。若第二参数判断单元211的判断结果为是，也即第一参数信息位于第二预设参数范围内，则第二参数判断单元211输出童锁锁定信号给童锁控制单元240，童锁控制单元240控制电子烟进入锁定状态，在锁定状态功率MOS管M保持断开，在本实施例中童锁控制单元240持续输出高电平信号给功率MOS管M，功率MOS管M保持截止。在本实施例中，童锁控制单元240包括触发器和开关控制单元，触发器用于对童锁锁定信号、后续的童锁解锁信号进行保持，触发器例如为SR触发器等，开关控制单元分别与触发器、状态检测单元150电连接，开关控制单元例如为与门、与非门、或门、或非门等，例如，开关控制单元包括与非门，与非门的两个输入端分别与触发器的输出端、状态检测单元150的一个输出端连接，童锁锁定信号使触发器的输出保持为低电平，从而经过与非门后保持为高电平(此时状态检测单元150输出抽吸信号，抽吸信号例如为高电平)，功率MOS管M保持截止；童锁解锁信号使触发器的输出保持为高电平，从而与非门的输出受状态检测单元150的输出影响，当状态检测单元150判断用户抽吸电子烟时，状态检测单元150输出抽吸信号给与非门，抽吸信号为高电平，此时开关控制单元控制功率MOS管M持续导通或者间断导通(例如PWM、PFM控制方式)。若第二参数判断单元211的判断结果为否，也即第一参数信息不位于第二预设参数范围内，则维持电子烟原先的童锁状态。
在本实施例中，电子烟的童锁状态分为锁定状态和解锁状态，其中，锁定状态即对应童锁保护功能，当电子烟处于锁定状态时用户抽吸电子烟，童锁控制单元240继续控制功率MOS管M1保持断开截止，从而发热元件130不会加热，进而烟油不会雾化以供用户抽吸，也即即使用户抽吸电子烟也不会出现烟雾。解锁状态对应解除童锁保护功能，此时烟油是否雾化受是否抽吸的控制，当用户抽吸电子烟时，童锁控制单元240控制功率MOS管M1持续导通或者间断导通，间断导通是指童锁控制单元240通过PWM方式、PFM方式输出方波信号，通过调整方波信号的占空比以用于控制输出功率、输出电压。
在本实施例中，通过接收第一参数信息；判断第一参数信息是否位于第二预设参数范围内，若判断结果为是，则控制电子烟进入锁定状态。本申请实施例通过第一参数信息、第二预设参数范围对抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，将第一参数信息位于第二预设参数范围的抽吸次数分辨为气压更小的抽吸状态(重吸)，并使电子烟进入锁定状态，通过这样设置，电子烟可以进一步分辨用户是正常抽吸电子烟，还是想要通过抽吸电子烟触发进入锁定状态，电子烟不容易混淆两者，可以降低用户正常抽吸电子烟时被误触发进入锁定状态的几率，可以减少用户的使用困扰。而且，通过重吸实现电子烟进入锁定状态，本实施例的电子烟在锁定保护后，可以防止儿童拿起电子烟模仿成人抽吸动作导致电子烟产品开始雾化工作，提升电子烟的使用安全性。再有，本实施例利用现有的状态检测单元150、气流传感器140就可以得到第一参数信息，不需要对电子烟进行大改，不需要增加硬件成本或者增加的硬件成本很小，从而缩减了电子烟进行锁定保护的硬件成本，解决现有技术中电子烟锁定成本较高的技术问题。
为了将重吸与一般的抽吸进一步区隔开，防止电子烟被轻易触发进入童锁锁定状态，降低误触发的概率，本申请实施例设置用户抽吸电子烟的吸力比较大，也即电子烟气流通道内的当前气压值要比较低，在本实施例中，当第一参数信息为当前频率值或者当前计数值时，第二预设参数范围的上限值与第一预设参数范围的上限值的比值小于或等于85％，较佳小于或等于70％，例如第一预设参数范围的上限值为970(以计数值为例进行说明)，基准计数值为1000时，此时第二预设参数范围的上限值小于或等于824，很明显比基准计数值小比较多，用户抽吸的吸力比较重才能到达这个范围，因此可以降低误触发的概率；当第一参数信息为当前电容值时，类似的，第二预设参数范围的下限值与第一预设参数范围的下限值的比值大于或等于115％，较佳大于或等于130％。在本申请的其他实施例中，当第一参数信息为当前频率值与基准频率值的比值、当前计数值与基准计数值的比值时，第二预设参数范围的上限值小于或等于85％。在本申请的其他实施例中，当所述第一参数信息为当前电容值与基准电容值的比值时，所述第二预设参数范围的下限值大于或等于115％。在本申请的其他实施例中，当所述第一参数信息为当前电容值相对基准电容值的差值与基准振荡电容值的比值、当前频率值相对基准频率值的差值与基准频率值的比值或者当前计数值相对基准计数值的差值与基准计数值的比值时，所述第二预设参数范围的下限值大于或等于15％。
请参见图29，在本实施例中，当第一参数信息为当前电容值、当前频率值或者当前计数值时，步骤接收第一参数信息具体包括：
接收状态检测单元150输出的第一参数信息。
其中，状态检测单元150本身可以得到第一参数信息，第二参数判断单元211通过状态检测单元150接收第一参数信息。本实施例充分利用现有电子烟中的气流传感器140、状态检测单元150，只需要增设第二参数判断单元211，第二参数判断单元211所要实现的功能既可以通过软体实现，也可以通过硬件实现，也可以通过软体和硬件结合实现，从而不需要增加新的硬件或者增加新的硬件较少，可以实现不增加成本或者增加少量成本就可以极大的降低电子烟误进入锁定状态的问题，提升了用户的使用便利性。
另外，在本申请另一实施例中，第一参数信息还可以为当前气压值、当前气压值与基准气压值的比值、当前气压值与基准气压值的差值或者当前气压值相对基准气压值的差值与基准气压值的比值，此时，第二预设参数范围对应为气压值范围、比值范围、差值范围。当第一参数信息为当前气压值或者当前气压值与基准气压值的比值时，此时第二预设参数范围的上限值小于第一预设参数范围的上限值，例如第一参数信息为当前气压值，此时第二预设参数范围为(a，A]，第二预设参数范围为(b，B],例如基准气压值为环境大气压，例如环境大气压为1个标准大气压，其中，A小于B，B小于环境大气压，a大于或等于b，A、a、B、b为正数，一般的，A比环境大气压小500pa，B比环境大气压小300pa，较佳A比环境大气压小500pa、600pa、800pa、1000pa、2000pa、3000pa，或者更小。另外，在本申请的其他实施例中，第二预设参数范围的下限值不设限，也即当当前气压值小于A即落入第二预设参数范 围内。另外，在本申请的其他实施例中，当第一参数信息为当前气压值与基准气压值的差值或者当前气压值相对基准气压值的差值与基准气压值的比值时，此时第二预设参数范围的下限值大于第一预设参数范围的下限值，第二预设参数范围的上限值小于或等于第一预设参数范围的上限值。类似的，第二预设参数范围的上限值与第一预设参数范围的上限值的比值小于或等于85％，较佳小于或等于70％、60％。在本申请的其他实施例中，当所述第一参数信息为当前气压值与基准气压值的比值时，所述第二预设参数范围的上限值小于或等于85％。在本申请的其他实施例中，当所述第一参数信息为当前气压值相对基准气压值的差值与基准气压值的比值时，所述第二预设参数范围的下限值大于或等于15％。在此实施例中，请参照图26，步骤接收第一参数信息具体包括：
S111:获取当前电容值、当前频率值或者当前计数值；
S112:根据当前电容值查找预存的电容值-气压值表、根据当前频率值查找预存的频率值-气压值表或者根据当前计数值查找预存的计数值-气压值表；
S113:获得电子烟气流通道内的当前气压值并输出；
S114:接收第一参数信息。
在此实施例中，为了获得电子烟的气流通道内的当前气压值，童锁控制电路200还包括气压获取单元，气压获取单元与状态检测单元150连接，第二参数判断单元211与气压获取单元连接，气压获取单元通过状态检测单元150、气流传感器140用于获取电子烟处于抽吸状态时气流通道内的当前气压值，第二参数判断单元211用于判断当前气压值是否位于第二预设参数范围内。具体说来，当吹气导致气流通道内气压较大时气流传感器140的电容的两个电极片之间的距离会比较大，从而其电容值会比较小，当抽吸导致气流通道内气压较小时气流传感器140电容的两个电极片之间距离比较小，从而其电容值相对会比较大，因而电容值与气流通道内的气压呈比例关系。在本申请的其他实施例中，电容值与频率值、计数值成反比例关系，从而频率值、计数值与气压值也呈比例关系。从而通过获得电容值、频率值或者计数值就可以对应获得气流通道内的当前气压值，两者的对应关系可以通过公式计算获得当前电压值，或者通过预先预存对应表格，其后查找对应表格获得当前电压信息。另外，在本申请的其他实施例中，当前气压值也可以直接通过传感器侦测获得。
在此实施例中，气压获取单元预存有电容值-气压值表、频率值-气压值表或者计数值-气压值表，其中，电容值-气压值表存储电容值与气压值的对应关系，频率值-气压值表存储频率值与气压值的对应关系，计数值-气压值表存储预设计数时长的计数值与气压值的对应关系，从而当获得当前电容值、当前频率值、当前计数值时通过查表就可以对应获得当前气压值。在本实施例中，气压获取单元、第二参数判断单元211较佳可以通过软体实现，也可以通过硬件实现。另外，在本申请的其他实施例中，气压获取单元可以不与状态检测单元150电连接，此时气压获取单元为气压传感器，气压传感器至少部分设置在电子烟的气流通道内，气压获取单元可以直接获得当前气压值，也即可以获得第一参数信息。
为了判断电子烟是否处于抽吸状态，请结合参见图27和图29，在本实施例中，童锁控制方法还包括:
S171:接收第一参数信息；
S172:判断第一参数信息是否位于第一预设参数范围内；

其中，当第一参数信息为当前电容值、当前频率值或者当前计数值，状态检测单元150包括第一参数生成单元、第一参数判断单元，第一参数生成单元分别与第一参数判断单元、第二参数判断单元211连接，第一参数生成单元生成第一参数信息后，第一参数判断单元接收第一参数信息，第一参数判断单元判断第一参数信息是否位于第一预设参数范围内，若判断结果为是，则第一参数判断单元输出电子烟由未抽吸状态转为抽吸状态的信息，也即输出抽吸信号，若判断结果为否，则第一参数判断单元维持原来的信号输出，例如输出未吸吹信号、吹气信号。另外，在本申请的其他实施例中，当第一参数信息为当前气压值时，童锁控 制电路包括第一参数判断单元，第一参数判断单元与气压获取单元连接，气压获取单元可以获得当前气压值，第一参数判断单元判断第一参数信息是否位于第一预设参数范围内，若判断结果为是，则第一参数判断单元输出电子烟由未抽吸状态转为抽吸状态的信息，也即输出抽吸信号，若判断结果为否，则第一参数判断单元维持原来的信号输出，例如输出未吸吹信号、吹气信号。进一步的，还可以要求连续多次判断为是，才输出抽吸信号，这样有利于降低气流串扰误触发的几率。在本申请中，第一参数判断单元、第二参数判断单元211可以为同一个参数判断单元，也可以为不同的参数判断单元。
在本实施例中，为了降低电子烟处于未抽吸状态时的功耗，步骤接收第一参数信息具体包括：
获取电子烟由未抽吸状态转为抽吸状态的信息；
触发接收第一参数信息。
其中，第二参数判断单元211在未收到抽吸信号前不工作，当第二参数判断单元211在接收到抽吸信号后，第二参数判断单元211被触发开始工作，第二参数判断单元211接收第一参数信息。这样设置，有利于降低电子烟的功耗。
在本实施例中，电子烟进入童锁锁定状态后，用户没法正常抽吸电子烟，当用户需要使用电子烟时，此时需要对电子烟进行解锁，以下描述电子烟如何进行解锁，以下描述的仅是一种进入童锁解锁状态的方式，本领域的技术人员还可以通过其他常规的方式使电子烟进入童锁解锁状态。另外，在本申请的其他实施例中，解锁方式可以与加锁方式一样，可以参见前面的描述，在此不再赘述。
请结合参阅图28和图29，在本实施例中，童锁控制方法还包括：
S21：接收第一参数信息；
其中，童锁控制电路200包括第四参数判断单元231，第四参数判断单元231用于接收第一参数信息，其中，第四参数判断单元231与第二参数判断单元211可以为不同的判断单元，也可以为同一参数判断单元。
在本实施例中，当处于吹气状态时，气流通道中气压较大，会高于未吸吹状态的气压，也即当前气压值会大于基准气压值，气流传感器140的电容的两个电极的间距相对未吸吹状态时要大，从而当前电容值会比未吸吹状态时小，当前频率值会比未吸吹状态时大，当前计数值会大于基准计数值。
S22:判断第一参数信息是否位于第四预设参数范围内，所述第四预设参数范围用于判断电子烟是否处于吹气状态；

其中，第四参数判断单元231在接收到第一参数信息后，第四参数判断单元231判断第一参数信息是否位于第四预设参数范围内，第四预设参数范围为预先计算获得，或者预先存储在第四参数判断单元231中。
当第一参数信息为当前电容值、当前电容值与基准电容值的比值时，此时第四预设参数范围对应为电容值范围、比值范围，第四预设参数范围的上限值会小于第一预设参数范围对应的下限值，第四预设参数范围的下限值可以不设限，也可以根据需要设限；当第一参数信息为当前气压值、当前频率值、当前计数值、当前气压值与基准气压值的比值、当前频率值与基准频率值的比值或者当前计数值与基准计数值的比值时，此时第四预设参数范围对应为气压值值范围、频率值范围、计数值范围或者比值范围，第四预设参数范围的下限值会大于第一预设参数范围对应的上限值，第四预设参数范围的上限值可以不设限，也可以根据需要设限。当第一参数信息为当前气压值与基准气压值的差值、当前电容值与基准电容值的差值、当前频率值与基准频率值的差值、当前计数值与基准计数值的差值、当前气压值相对基准气压值的差值与基准气压值的比值、当前电容值相对基准电容值的差值与基准振荡电容值的比值、当前频率值相对基准频率值的差值与基准频率值的比值或者当前计数值相对基准计数值的差值与基准计数值的比值时，此时第四预设参数范围与第一预设参数范围的大小关系可以不做限定，两者范围可以相同，也可以不同。
其中，童锁控制电路200包括第四计时单元232和第四计数单元233，第四计时单元232与第四参数判断单元231电连接，第四计数单元233与第四参数判断单元231电连接，若第四参数判断单元231的判断结果为是，则第四参数判断单元231输出吹气信号，第四计时单元232被触发开始计时，第四计时单元232从0开始计时，第四计数单元233被触发开始计数，并将此次也进行计数，也即此时第四计数单元233的计数为1；若第四参数判断单元231的判断结果为否，则第四参数判断单元231不会输出吹气信号，第四计时单元232维持原先的状态，第四计数单元233维持原先的状态。在本实施例中，当第四计时单元232被触发开始计时后，第四计时单元232会一直在计时，直到第四计时单元232被复位置零，此后第四计时单元232停止计时。在本实施例中，吹气信号也会输出给童锁控制单元240。
在本实施例中，当第四计时单元232被触发计时、第四计数单元233被触发计数后，当第四参数判断单元231又接收到第一参数信息，并又一次判断第一参数信息位于第四预设参数范围内，则第四计数单元233的第四计数加1，此时第四计数为2，同时，第四计时单元232在持续进行第四计时。
S24：判断在第四预设时长内第四计数是否大于或等于第四预设数量，其中，第四预设数量大于或等于2；
其中，童锁控制电路200还包括第四计时计数判断单元234，第四计时计数判断单元234分别与第四计数单元233、第四计时单元232电连接，当第四计时计数判断单元234判断第四计时单元232的计时时长在第四预设时长内，且第四计数单元233计数大于或等于第四预设数量，第四计时计数判断单元234输出童锁解锁信号。在本实施例中，第四预设时长一般小于或等于5s，例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第四预设数量大于或等于2，例如为2、3、4、5、6等，较佳为3，第四预设数量一般小于或等于6次，方便用户操作。
在本实施例中，第四计时计数判断单元234与第四计时单元232、第四计数单元233实时连接，当第四计时计数判断单元234获取第四计数单元233到达第四预设数量且第四计时单元232未到达第四预设时长时，第四计时计数判断单元234输出童锁解锁信号，或者第四计时计数判断单元234等第四计时单元232计时时长到达第四预设时长时才输出童锁解锁信号。在本申请的其他实施例中，第四计时计数判断单元234与第四计时单元232、第四计数单元233连接，当第四计时单元232到达第四预设时长时第四计时单元232输出信号给第四计时计数判断单元234，第四计时计数判断获取此时第四计数单元233的计数，然后判断第四计数是否大于或等于第四预设数量，若大于或等于第四预设数量，则输出童锁解锁信号，若小于第四预设数量，则维持原来的信号输出。
S24:若判断结果为是，则控制电子烟进入解锁状态，其中，在解锁状态所述电子烟处于抽吸状态时所述功率MOS管M1持续导通或者间断导通。
其中，若第四计时计数判断单元234判断的结果为是，也即在第四预设时长内计数的数量大于或等于第四预设数量，则第四计时计数判断单元234输出童锁解锁信号给童锁控制单元240，童锁控制单元240控制电子烟进入解锁状态，在解锁状态电子烟处于抽吸状态时功率MOS管M1持续导通或者间断导通，也即此时功率MOS管M1受用户是否抽吸的控制，在本实施例中电子烟处于抽吸状态时童锁控制单元240持续输出低电平信号或者间断输出低电平信号给功率MOS管M1，功率MOS管M1持续导通或者间断导通，当功率MOS管M1导通时，发热元件130加热以雾化烟油，从而雾化后的烟油可供被用户抽吸。
在本实施例中，通过对吹气进行计时和计数实现解锁，在没有增加蓝牙/NFC等设计以及机械结构的同时，实现了有效的解锁效果，从而缩减了电子烟的进行解锁的硬件成本，解决现有技术中电子烟解锁成本较高的技术问题。而且，本申请的解锁方式不容易被儿童察觉，电子烟在锁定后不容易被儿童解锁，有利于提升电子烟的安全性。另外，在本申请的其他实施例中，同判断抽吸状态一样，也可以通过当前计数值来判断是否进行吹气。
在本实施例中，童锁控制方法还包括：再次获取第一参数信息位于第四预设参数范围内的信息，第四计数加1。
具体而言，在第四计数单元233触发第四计数和第四计时单元232触发第四计时后，第四计时单元232和第四计数单元233未停止工作，第四计时单元232、第四计数单元233再次(再次是指第四计数单元233中第四计数的数值至少为1)获取第一参数信息位于第四预设参数范围内的信息，则第四计数单元233在原来计数的基础上加1，例如原来第四计数单元233的计数值为1，再次获取第一参数信息位于第四预设参数范围内的信息，也即接收到由未吸吹状态转为吹气状态的信息，则第四计数单元233的计数加1，也即计数值变为2；第四计时单元232继续工作持续计时，也即第四计时单元232在触发计时后，只要不收到停止计时或者复位的信号，则第四计时单元232一直在计时。
在本实施例中，童锁控制方法还包括：若第四计时单元232的计时时长达到第四预设时长，则第四计数置零，且第四计时单元232复位置零。
其中，不论第四计时计数判断单元234的判断结果为是还是否，只要第四计时单元232的计时时长达到第四预设时长，则第四计时单元232复位置零，同时第四计时单元232发送信号给第四计数单元233，第四计数单元233进行置零，也即此时第四计时单元232停止计时，第四计数单元233停止计数，而且，计时时长置零，第四计数均置零，第四计时单元232、第四计数单元233恢复初始状态，方便后面的检测。
在本实施例中，童锁控制方法还包括：若第四计时单元232的计时时长小于第四预设时长且第四计数达到第四预设参数范围，则第四计数置零，且第四计时单元232复位置零。
其中，若第四计时计数判断单元234获取第四计数单元233的第四计数达到第四预设参数范围，且第四计时单元232计时时长小于第四预设时长，则第四计时计数判断单元234输出信号给第四计时单元232、第四计数单元233，第四计时单元232复位置零，第四计数单元233进行置零，该信号可以与童锁解锁信号一样，也可以是不同的信号。

第五实施例
本申请第五实施例提供一种电子烟，请结合参见图31和图38，电子烟包括电池110、童锁控制电路200、发热元件130、气流传感器140、功率MOS管M1等，童锁控制电路200包括状态检测单元150。童锁控制电路200分别与电池110、气流传感器140、功率MOS管M1等电连接。在本实施例中，电池110例如为锂电池、镍镉电池、镍氢电池等可充电电池，电池110也可以为不可充电电池；状态检测单元150与气流传感器140电连接，状态检测单元150用于判断电子烟是否被抽吸和/或被吹气，并输出对应信号，状态检测单元150的一个具体实现方式可参见本领域的在先申请，或者为本领域技术人员知晓的其他常规的状态检测单元。在本实施例中气流传感器140为电容式气流传感器140，例如为电容式MEMS传感器或电容式咪头等，气流传感器140位于电子烟的气流通道内，气流传感器140包括电容，状 态检测单元150通过电容的电容值等的变化判断电子烟是否处于抽吸状态、吹气状态、未吸吹状态(对应用户未使用时的状态)。童锁控制电路200与功率MOS管M1的控制端电连接，童锁控制电路200用于控制功率MOS管M1是否导通，功率MOS管M1经由雾化端AT与发热元件130串联形成串联支路，串联支路的一端经由电源供电端BAT与电池110的正极电连接，串联支路的另一端经由电源接地端GND与电池110的负极电连接。在本实施例中以功率MOS管M1为PMOS管为例进行说明，当然，功率MOS管M1也可以为NMOS管。在本实施例中，功率MOS管M1、童锁控制电路200可以位于同一个芯片，该芯片一般称为系统控制芯片。但本申请不限于此，在本申请的其他实施例中，功率MOS管M1、童锁控制电路200可以位于不同的芯片上。在本实施例中，发热元件130例如为发热丝、加热丝、包含发热丝或者加热丝的陶瓷座、或者其他常规的发热元件130。在本实施例中，当童锁控制电路200输出低电平控制功率MOS管M1导通时发热元件130加热以使烟油雾化，当童锁控制电路200输出高电平控制功率MOS管M1断开截止时发热元件130停止加热。
在本实施例中，状态检测单元150与气流传感器140电连接，以用于判断电子烟是否被抽吸或者被吹气或者处于未吹气也未抽吸的状态(未吸吹状态)，当用户抽吸电子烟或者向电子烟吹气时，气流传感器140的电容的两个电极片之间气压会改变，导致两个电极片之间的距离会随之改变，进而引起气流传感器140的电容值改变，状态检测单元150将电容值改变转换为频率值改变或者计数值改变，通过将电容值、频率值或者计数值与预设的参数范围进行比较，状态检测单元150就可以判断电子烟是否被抽吸处于抽吸状态、被吹气处于吹气状态或者处于未吸吹状态。另外，在本申请的其他实施例中，还可以不通过状态检测单元判断电子烟是否处于抽吸状态、吹气状态。
为了区分正常抽吸和触发进入解锁状态的抽吸，以降低正常抽吸时被误触发进入解锁状态的概率，并增加小孩操作进入解锁状态的难度，本申请的发明人经过大量实验后提出以下方案：对电子烟的抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，气压较小(用户抽吸的吸力较小)的抽吸状态一般对应用户正常的抽吸，气压更小(用户抽吸的吸力较大)的抽吸状态对应用户想要进入解锁状态的抽吸或者用户偶然的重吸，不管是处于气压较小的抽吸状态，还是处于气压更小的抽吸状态，电子烟均会判断为抽吸状态，本申请通过第一参数信息是否位于第二预设参数范围内判断是否为气压更小的抽吸状态。
具体而言，第一参数信息表征电子烟气流通道内的气压状况，气压状况例如为气压大小、气压的变化状况等，第一参数信息与气流通道内的气压呈对应关系，本实施例设计当第一参数信息位于第二预设参数范围内时代表此时处于气压更小的抽吸状态，当第一参数信息位于第二预设参数范围之外且位于第一预设参数范围之内时代表气压较小的抽吸状态，其中，第二预设参数范围位于第一预设参数范围内，也即只要第一参数信息位于第二预设参数范围内，第一参数信息必然位于第一预设参数范围内，表示此时电子烟处于抽吸状态且是重吸，当第一参数信息位于第一预设参数范围内时，第一参数信息可能位于第二预设参数范围内(重吸)，也可能不位于第二预设参数范围内(正常抽吸)。
在本实施例中，第一参数信息包括当前电容值、当前电容变化量、当前频率值、当前频率变化量、当前计数值、当前计数变化量、当前电容值与基准电容值的比值、当前频率值与基准频率值的比值、当前计数值与基准计数值的比值、当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值等，此时第一参数信息可以通过状态检测单元150直接获得。当电子烟未被抽吸也未被吹气时，也即电子烟处于未吸吹状态时，此时电容的电极片未变形，此时的当前电容值即为基准电容值，此时基准电容值是采集获得或者转换获得，此时对应的当前频率值即为基准频率值，此时预设计数时长内的振荡周期数为当前计数值，也即为基准计数值；另外，基准电容值、基准频率值、基准计数值也可以预设；当前电容变化量、当前频率变化量或者当前计数变化量为对应当前值与对应基准值之间的差值。当用户轻吸导致电子烟气流通道内的当前气压较小时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变小，当前电容值会较大，当前频率值会较小，预设计数时长内的振荡周期数会较小，也即当前计数值会较小，当前电容 变化量、当前频率变化量或者当前计数变化量会较大，当前电容值与基准电容值的比值会较大，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会较小，当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值会较大；当用户重吸导致电子烟气流通道内的当前气压值更小时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变更小，当前电容值会更大，当前频率值会更小，预设计数时长内的振荡周期数会更小，也即当前计数值会更小，当前电容变化量、当前频率变化量或者当前计数变化量会更大，当前电容值与基准电容值的比值会更大，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会更小，当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值会更大。当用户吹气导致电子烟气流通道内的当前气压值相对未吹吸状态变大时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时变大，气流传感器140的当前电容值会变小，当前频率值会变大，当前计数值会比基准计数值大。
当气流通道内气压更小时气流传感器140的电容变形更大，电容的两个电极片之间的距离更小，从而其当前电容值会更大，当前计数值会更小，当前频率值会更小，当前电容变化量、当前频率变化量或者当前计数变化量会更大，当前电容值与基准电容值的比值会更大，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会更小，当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值会更大；当气流通道内气压较小时气流传感器140的电容变形较大，电容的两个电极片之间的距离较小，从而其电容值会较大，当前计数值会较小，当前频率值会较小，当前电容变化量、当前频率变化量或者当前计数变化量会较大，当前电容值与基准电容值的比值会较大，当前频率值与基准频率值的比值、当前计数值与基准计数值的比值会较小，当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值会较大。因而当前电容值、当前计数值、当前频率值、当前电容变化量、当前频率变化量、当前计数变化量等均与气流通道内的气压呈比例关系。
由于本申请设计成用户重吸才可能进入童锁解锁状态，当第一参数信息为当前电容值、当前电容变化量、当前频率变化量、当前计数变化量、当前电容值与基准电容值的比值、当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值时，第二预设参数范围对应为电容值范围、电容变化量范围、频率变化量范围、计数变化量范围或者比值范围，第二预设参数范围的下限值要大于第一预设参数范围的下限值，第二预设参数范围的上限值小于或等于第一预设参数范围的上限值，例如第二预设参数范围为(a，A]，第一预设参数范围(b，B],其中，a大于b，A小于或等于B，A、a、B、b为正数。另外，在本申请的其他实施例中，第二预设参数范围的上限值不设限，也即当前电容值、当前电容变化量、当前频率变化量或者当前计数变化量大于a即落入第二预设参数范围内。当第一参数信息为当前频率值、当前计数值、当前频率值与基准频率值的比值或者当前计数值与基准计数值的比值时，第二预设参数范围对应为频率值范围、计数值范围或者比值范围，第二预设参数范围的上限值要小于第一预设参数范围的上限值，第二预设参数范围的下限值大于或等于第一预设参数范围的下限值，例如第一参数信息为当前计数值时，第二预设参数范围为[m,M)，例如M为950，第一预设参数范围为[n,N),例如N为970，其中，M小于N，m大于或等于n，M、m、N、n为正整数。另外，在本申请的其他实施例中，第二预设参数范围的下限值不设限，也即当前频率值或者当前计数值小于M即落入第二预设参数范围内。
另外，在本申请的其他实施例中，第一参数信息还可以包括当前气压值、当前气压变化量(当前气压值相对基准气压值的差值)、当前气压值与基准气压值的比值、当前气压变化量与基准气压值的比值等。当电子烟未被抽吸也未被吹气时，也即电子烟处于未吸吹状态时，此时电容的电极片未变形，此时电子烟气流通道内的气压值即为基准气压值，也即为大气压值，此时基准气压值是采集获得或者转换获得；另外，基准气压值也可以预设。当用户轻吸导致电子烟气流通道内的当前气压值较小时，气流传感器140的电容的两个电极片之间的距 离会相对未吸吹状态时会变小，当前电容值会较大，当前气压值相对基准气压值的差值会较大，也即当前气压变化量会较大，当前气压值与基准气压值的比值会较小，当前气压变化量与基准气压值的比值会较大；当用户重吸导致电子烟气流通道内的当前气压值更小时，气流传感器140的电容的两个电极片之间的距离会相对未吸吹状态时会变更小，当前电容值会更大，当前气压值相对基准气压值的差值会更大，也即当前气压变化量会更大，当前气压值与基准气压值的比值会更小，当前气压变化量与基准气压值的比值会更大。
为了获得电子烟的气流通道内的当前气压值或当前气压变化量，在此实施例中童锁控制电路200还包括气压获取单元，气压获取单元与状态检测单元150连接，气压获取单元通过状态检测单元150、气流传感器140用于获取电子烟气流通道内的当前气压值，进而通过运算可以获得当前气压变化量。具体说来，当吹气导致气流通道内当前气压值较大时气流传感器140的电容的两个电极片之间的距离会比较大，从而其当前电容值会比较小，当抽吸导致气流通道内当前气压值较小时气流传感器140电容的两个电极片之间距离比较小，从而其当前电容值相对会比较大，因而当前电容值与气流通道内的当前气压值呈比例关系。在本申请的其他实施例中，当前电容值与当前频率值、当前计数值成反比例关系，从而当前频率值、当前计数值与当前气压值也呈比例关系。在本申请的其他实施例中，处于抽吸状态的当前电容值相对基准电容值的变化量也会与气流通道内的当前气压值呈比例关系。在本申请的其他实施例中，处于抽吸状态的当前频率值相对基准频率值的变化量也会与气流通道内的当前气压值呈比例关系，或者处于抽吸状态的当前计数值相对基准计数值的变化量也会与气流通道内的当前气压值呈比例关系。从而通过获得当前电容值、相对未吸吹状态时的当前电容变化量、当前频率值、相对未吸吹状态时的当前频率变化量、当前计数值、相对未吸吹状态时的当前计数变化量就可以对应获得气流通道内的当前气压值，两者的对应关系可以通过公式计算获得当前气压信息，或者通过预先预存对应表格，其后查找对应表格获得当前气压值，进而通过算术运算就可以得到当前气压变化量。另外，在本申请的其他实施例中，当前气压值也可以直接通过传感器侦测获得。
在此实施例中，气压获取单元预存有电容值-气压值表、频率值-气压值表、计数值-气压值表、电容变化量-气压值表、频率变化量-气压值表或者计数变化量-气压值表，其中，电容值-气压值表存储电容值与气压值的对应关系，频率值-气压值表存储频率值与气压值的对应关系，计数值-气压值表存储预设计数时长的计数值与气压值的对应关系，电容变化量-气压值表存储电容变化量与气压值的对应关系，频率变化量-气压值表存储频率变化量与气压值的对应关系，计数变化量-气压值表存储预设计数时长的计数变化量与气压值的对应关系，从而当获得当前电容值、当前频率值、当前计数值、当前电容变化量、当前频率变化量、当前计数变化量时通过查表就可以对应获得当前气压值。在此实施例中，气压获取单元较佳可以通过软体实现，也可以通过硬件实现，还可以通过软硬件结合实现。另外，在本申请的其他实施例中，气压获取单元可以不与状态检测单元150电连接，此时气压获取单元为气压传感器，气压传感器至少部分设置在电子烟的气流通道内，气压获取单元可以直接获得当前气压值，进而获得当前气压变化量、当前气压值与基准气压值的比值、当前气压变化量与基准气压值的比值，例如当前气压值减去基准气压值就可以获得当前气压变化量。
在此实施例中，当第一参数信息为当前气压值或者当前气压值与基准气压值的比值时，由于本申请设计成用户重吸才可能进入童锁锁定状态，从而第二预设参数范围为气压值、比值的范围，第二预设参数范围的上限值要小于第一预设参数范围的上限值，第二预设参数范围的下限值大于或等于第一预设参数范围的下限值，例如第一参数信息为当前气压值，第二预设参数范围为(c，C]，第一预设参数范围(d，D],例如基准气压值为环境大气压，例如环境大气压为1个标准大气压，其中，C小于D，D小于环境大气压，c大于或等于d，C、c、D、d为正数，一般的，C比环境大气压小500pa，D比环境大气压小300pa，较佳C比环境大气压小500pa、600pa、1000pa、2000pa等。另外，在本申请的其他实施例中，第二预设参数范围的下限值不设限，也即当前气压值小于C即落入第二预设参数范围内。
当第一参数信息为当前气压变化量或者当前气压变化量与基准气压值的比值时，当气流 通道内气压更小时，当前气压变化量会更大，当前气压变化量与基准气压值的比值更大；当气流通道内气压较小时，当前气压变化量会较大，当前气压变化量与基准气压值的比值较大，因而当前气压变化量、当前气压变化量与基准气压值的比值与气流通道内的气压呈比例关系。此时第二预设参数范围为气压变化量范围、比值范围，第二预设参数范围的下限值大于第一预设参数范围的下限值，第二预设参数范围的上限值小于或等于第一预设参数范围的上限值，例如第二预设参数范围为[E,e)，例如E为500pa、1000pa，第一预设参数范围[F,f),例如F为300pa，其中，E大于F，e小于或等于f，E、e、F、f为正数。另外，在本申请的其他实施例中，第二预设参数范围的上限值不设限，也即只要当前气压变化量大于或等于E即落入第二预设参数范围内。
请继续参见图38，在本申请中，当电子烟处于抽吸状态时，为了判断第一参数信息是否位于第二预设参数范围内，本实施例童锁控制电路200还包括第二参数判断单元211，第二参数判断单元211与状态检测单元150或者气压获取单元连接，状态检测单元150或者气压获取单元本身就知道第一参数信息，从而状态检测单元150或者气压获取单元输出第一参数信息给第二参数判断单元211，第二参数判断单元211用于接收第一参数信息并判断第一参数信息是否位于第二预设参数范围内，进而可以区分用户是正常抽吸还是进入解锁状态的抽吸，经过这样区分，可以降低用户把玩电子烟时误触发解锁的概率，而且可以增加儿童对电子烟解锁的难度：儿童不太容易通过视觉区分开用户的轻吸或者重吸。
请结合参见图31、图32和图38，本申请实施例提供一种电子烟的童锁控制方法，包括以下步骤：S11：接收第一参数信息；
其中，第二参数判断单元211与状态检测单元150连接，状态检测单元150产生第一参数信息，并输出第一参数信息，第二参数判断单元211接收第一参数信息。另外，在本申请的其他实施例中，第二参数判断单元211与气压获取单元连接。
在本实施例中，状态检测单元150本身可以识别电子烟是否处于抽吸状态或者吹气状态，当用户抽吸电子烟时，状态检测单元150通过气流传感器140识别电子烟处于抽吸状态，此时状态检测单元150判断第一参数信息位于第一预设参数范围内，状态检测单元150输出抽吸信号，当用户吹气时，状态检测单元150通过气流传感器140识别电子烟处于吹气状态，此时状态检测单元150输出吹气信号，当电子烟既不被抽吸，也不被吹气时，此时状态检测单元150识别电子烟处于未吸吹状态，状态检测单元150输出未吸吹信号。童锁控制电路200接收状态检测单元150的输出信号，从而获取电子烟的状态。当状态检测单元150由输出未吸吹信号转为输出抽吸信号或者吹气信号时，童锁控制电路200获取电子烟由未吸吹状态转为抽吸状态或者吹气状态。在本实施例中，未抽吸状态包括未吸吹状态、吹气状态。
S12:判断第一参数信息是否位于第二预设参数范围内，其中，所述第二预设参数范围位于第一预设参数范围内，所述第一预设参数范围用于判断电子烟是否处于抽吸状态；
S13：若判断结果为是，则触发进行第二计时并触发进行第二计数；
其中，第二参数判断单元211在接收到第一参数信息后，第二参数判断单元211判断第一参数信息是否位于第二预设参数范围内，第二预设参数范围为预先计算获得，或者预先存储在第二参数判断单元211中。其中，童锁控制电路200包括第二计时单元216和第二计数单元215，第二计时单元216与第二参数判断单元211电连接，第二计数单元215与第二参数判断单元211电连接，若第二参数判断单元211的判断结果为是，则第二参数判断单元211输出参数有效信号，第二计时单元216被触发开始计时，第二计时单元216从0开始计时，第二计数单元215被触发开始计数，并将此次也进行计数，也即此时第二计数单元215的计数为1；若第二参数判断单元211的判断结果为否，则第二参数判断单元211输出参数无效信号，第二计时单元216维持原先的状态，第二计数单元215维持原先的状态。在本实施例中，当第二计时单元216被触发开始计时后，第二计时单元216会一直在计时，直到第二计时单元216被复位置零，此后第二计时单元216停止计时。
当第二计时单元216被触发计时、第二计数单元215被触发计数后，当第二参数判断单元211又接收到第一参数信息，并又一次判断第一参数信息位于第二预设参数范围内，也即 又输出参数有效信号，则第二计数单元215的第二计数加1，此时第二计数为2，同时，第二计时单元216在持续进行第二计时。
S14：判断在第二预设时长内第二计数是否大于或等于第二预设数量，其中，第二预设数量大于或等于2；
其中，童锁控制电路200还包括第二计时计数判断单元217，第二计时计数判断单元217分别与第二计数单元215、第二计时单元216连接，当第二计时计数判断单元217判断第二计时单元216的计时时长在第二预设时长内，且第二计数单元215的第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁解锁信号。在本实施例中，第二预设时长一般小于或等于5s，第二预设时长例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第二预设数量为大于或等于2的整数，例如为2、3、4、5、6等，较佳为3，第二预设数量一般小于或等于6次，方便用户操作。例如，第二预设时长为2秒，第二预设数量为3，则在2秒内第二计数大于或等于3，第二计时计数判断单元217输出童锁解锁信号。
在本实施例中，第二计时计数判断单元217与第二计时单元216、第二计数单元215实时电连接，当第二计时计数判断单元217获取第二计数到达第二预设数量且第二计时单元216未到达第二预设时长时，第二计时计数判断单元217输出童锁解锁信号，或者第二计时计数判断单元217等第二计时单元216计时时长到达第二预设时长时才输出童锁解锁信号。在本申请的其他实施例中，第二计时计数判断单元217与第二计时单元216、第二计数单元215连接，当第二计时单元216到达第二预设时长时第二计时单元216输出信号给第二计时计数判断单元217，第二计时计数判断单元217获取此时第二计数单元215的第二计数，然后判断第二计数是否大于或等于第二预设数量，若第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁解锁信号，若第二计数小于第二预设数量，则第二计时计数判断单元217维持原来的信号输出。
S15：若判断结果为是，则控制电子烟进入解锁状态，在解锁状态所述电子烟处于抽吸状态时所述功率MOS管持续导通或者间断导通。
其中，童锁控制电路200还包括童锁控制单元240，童锁控制单元240与第二计时计数判断单元217电连接。若第二计时计数判断单元217的判断结果为是，也即在第二预设时长内第二计数大于或等于第二预设数量，则第二计时计数判断单元217输出童锁解锁信号给童锁控制单元240，童锁控制单元240控制电子烟进入解锁状态，在解锁状态电子烟处于抽吸状态时功率MOS管M1持续导通或者间断导通，也即此时功率MOS管M1受用户是否抽吸的控制，在本实施例中电子烟处于抽吸状态时童锁控制单元240持续输出低电平信号或者间断输出低电平信号给功率MOS管M1，功率MOS管M1持续导通或者间断导通，当功率MOS管M1导通时，发热元件130加热以雾化烟油，从而雾化后的烟油可供被用户抽吸。在本实施例中，童锁控制单元240包括触发器和开关控制单元，触发器用于对童锁解锁信号、后续的童锁锁定信号进行保持，触发器例如为SR触发器等，开关控制单元分别与触发器、状态检测单元150电连接，开关控制单元例如为与门、与非门、或门、或非门等，例如，开关控制单元包括与非门，与非门的两个输入端分别与触发器的输出端、状态检测单元150的一个输出端连接，童锁解锁信号使触发器的输出保持为高电平，从而与非门的输出受状态检测单元150的输出影响，当状态检测单元150判断用户抽吸电子烟时，状态检测单元150输出抽吸信号给与非门，抽吸信号为高电平，此时开关控制单元控制功率MOS管M1持续导通或者间断导通(例如PWM、PFM控制方式)；童锁锁定信号使触发器的输出保持为低电平，从而经过与非门后保持为高电平(此时状态检测单元150输出抽吸信号，抽吸信号例如为高电平)，功率MOS管M1保持截止。若第二计时计数判断单元217的判断结果为否，也即在第二预设时长内第二计数小于第二预设数量，则维持电子烟原先的童锁状态，且第二计数置0，第二计时复位置零。
在本实施例中，电子烟的童锁状态分为锁定状态和解锁状态，其中，锁定状态即对应童锁保护功能，当电子烟处于锁定状态时用户抽吸电子烟，童锁控制单元240继续控制功率MOS 管M1保持断开截止，从而发热元件130不会加热，进而烟油不会雾化以供用户抽吸，也即即使用户抽吸电子烟也不会出现烟雾。解锁状态对应解除童锁保护功能，此时烟油是否雾化受是否抽吸的控制，当用户抽吸电子烟时，童锁控制单元240控制功率MOS管M1持续导通或者间断导通，间断导通是指童锁控制单元240通过PWM方式、PFM方式输出方波信号，通过调整方波信号的占空比以用于控制输出功率、输出电压。
在本实施例中，通过接收第一参数信息；判断第一参数信息是否位于第二预设参数范围内，若判断结果为是，则触发进行第二计时并触发进行第二计数；判断在第二预设时长内第二计数是否大于或等于第二预设数量，若判断结果为是，则控制电子烟进入解锁状态。本申请实施例通过第一参数信息、第二预设参数范围对抽吸状态进一步细分，分为气压更小的抽吸状态和气压较小的抽吸状态，将第一参数信息位于第二预设参数范围的抽吸次数分辨为气压更小的抽吸状态(重吸)，并进行第二计数，并且在第二预设时长内第二计数大于或等于第二预设数量才使电子烟进入解锁状态，通过这样设置，电子烟可以进一步分辨用户是正常抽吸电子烟，还是想要通过抽吸电子烟触发进入解锁状态，可以降低用户把玩抽吸电子烟时被误触发解除锁定的几率，可以减少用户的使用困扰；而且，需要重吸才可能解除锁定，一般小孩不容易将抽吸再分辨为重吸和一般的抽吸，从而小孩解除电子烟锁定状态的难度较大，提升了电子烟的安全性。而且，本实施例利用现有的状态检测单元150、气流传感器140就可以得到第一参数信息，不需要对电子烟进行大改，不需要增加硬件成本或者增加的硬件成本很小，从而缩减了电子烟进行锁定保护的硬件成本，解决现有技术中电子烟锁定成本较高的技术问题。
在本实施例中，童锁控制方法还包括：再次获取第一参数信息位于第二预设参数范围内的信息，第二计数加1。
具体而言，在第二计数单元215触发第二计数和第二计时单元216触发进行第二计时后，第二计时单元216和第二计数单元215未停止工作，当电子烟转为未抽吸状态，其后，当用户再次抽吸电子烟，再次实时获取第一参数信息，若第二计数单元215再次获取第一参数信息位于第二预设参数范围内的信息，也即第二计数单元215又收到参数有效信号，则第二计数单元215在原来第二计数的基础上加1，例如原来第二计数单元215的计数值为1，再次获取第一参数信息位于第二预设参数范围内的信息，则第二计数单元215的第二计数加1，也即第二计数变为2，同时，第二计时单元216在触发第二计时后，第二计时单元216一直在计时；若此次第二计数单元215没有获取第一参数信息位于第二预设参数范围内的信息，也即第二计数单元215没有收到参数有效信号，则第二计数保持不变，此时第二计时单元216也在计时。
在本实施例中，童锁控制方法还包括：若第二计时达到第二预设时长，则第二计数置零，且第二计时复位置零。
其中，不论第二计时计数判断单元217的判断结果为是还是不为是，只要第二计时单元216的计时时长达到第二预设时长，则第二计时单元216复位置零，同时第二计时单元216发送信号给第二计数单元215，第二计数单元215进行置零，也即此时第二计时单元216停止计时，计时时长置零，第二计时单元216、第二计数单元215恢复初始状态，方便后面信号的检测。在本实施例中，第二计时计数判断单元217在第二计时单元216、第二计数单元215复位置零前已完成判断。
在本实施例中，童锁控制方法还包括：若第二计时小于第二预设时长且第二计数达到第二预设数量，则第二计数置零，且第二计时复位置零。
其中，若第二计时计数判断单元217获取第二计数达到第二预设数量，且第二计时单元216计时时长小于第二预设时长，则第二计时计数判断单元217输出信号给第二计时单元216、第二计数单元215，第二计时单元216进行复位置零，第二计数单元215置零，该信号可以与童锁解锁信号一样，也可以是不同的信号。
请参见图38，在本实施例中，步骤接收第一参数信息具体包括：
接收状态检测单元150输出的第一参数信息。
在本实施例中，第一参数信息为当前电容值、当前频率值、当前计数值、当前电容变化量、当前频率变化量、当前计数变化量、当前电容值与基准电容值的比值、当前频率值与基准频率值的比值、当前计数值与基准计数值的比值、当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值，状态检测单元150本身可以得到第一参数信息，第二参数判断单元211通过状态检测单元150接收第一参数信息，也即接收当前电容值、当前频率值、当前计数值、当前电容变化量、当前频率变化量、当前计数变化量、当前电容值与基准电容值的比值、当前频率值与基准频率值的比值、当前计数值与基准计数值的比值、当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值。本实施例充分利用现有电子烟中的气流传感器140、状态检测单元150，只需要增设第二参数判断单元211，第二参数判断单元211所要实现的功能既可以通过软体实现，也可以通过硬件实现，也可以通过软体和硬件结合实现，从而不需要增加新的硬件或者增加新的硬件较少，可以实现不增加成本或者增加少量成本就可以极大的降低电子烟误进入解锁状态的问题，提升了用户的使用便利性。
另外，在本申请的其他实施例中，请参见图33和图38,当第一参数信息为当前气压值、当前气压变化量、当前气压值与基准气压值的比值、当前气压变化量与基准气压值的比值时，步骤接收第一参数信息具体包括：S111:通过状态检测单元150获取当前电容值、当前频率值、当前计数值、相对未吸吹状态时的当前电容变化量、相对未吸吹状态时的当前频率变化量或者相对未吸吹状态时的当前计数变化量；
S112:根据当前电容值查找预存的电容值-气压值表、根据当前频率值查找预存的频率值-气压值表、根据当前计数值查找预存的计数值-气压值表、根据当前电容变化量查找预存的电容变化量-气压值表、根据当前频率变化量查找预存的频率变化量-气压值表或者根据当前计数变化量查找预存的计数变化量-气压值表；
S113:接收电子烟气流通道内的第一参数信息。
在此实施例中，气压获取单元中预存有电容值-气压值表、频率值-气压值表、计数值-气压值表、电容变化量-气压值表、频率变化量-气压值表、计数变化量-气压值表其中之一，该对应表是提前计算好或者测试好并预存在气压获取单元中，电容值-气压值表、频率值-气压值表、计数值-气压值表、电容变化量-气压值表、频率变化量-气压值表、计数变化量-气压值表的两个参数可以是一一对应关系，也可以是范围与值的对应关系，例如电容值G对应气压值g，电容值H对应气压值h，电容值范围[G，H]对应气压值g，等情形，气压获取单元通过状态检测单元150获取当前电容值、当前频率值、当前计数值、当前电容变化量、当前频率变化量、当前计数变化量，然后通过查找预存的表获得当前气压值，进而获得当前气压变化量，其后第二参数判断单元211判断第一参数信息是否位于第二预设参数范围内，若位于第二预设参数范围内，则输出参数有效信号给第二计数单元280，第二计数加1，若不位于第二预设参数范围内，则输出参数无效信号给第二计数单元280，第二计数不变。此实施例充分利用现有的气流传感器140、状态检测单元150，只需要增设气压获取单元、第二参数判断单元211，气压获取单元、第二参数判断单元211所要实现的功能既可以通过软体实现，也可以通过硬件实现，也可以通过软体和硬件结合实现，从而不需要增加新的硬件或者增加新的硬件较少，可以实现不增加成本或者增加少量成本就可以极大的降低电子烟误进入解锁状态的问题，提升了用户的使用便利性。另外，在本申请的其他实施例中，也可以不共用状态检测单元150、气流传感器140，此时气压获取单元为气压传感器，气压传感器可以直接获得气流通道内的当前气压值，进而获得当前气压变化量，气压获取单元与第二参数判断单元211连接，第二参数判断单元211与第二计数单元280连接，气压获取单元用于电子烟处于抽吸状态时获得气流通道内的当前气压值或者当前气压变化量，第二参数判断单元211用于判断当前气压值或者当前气压变化量是否位于第二预设参数范围内，若位于第二预设参数范围内，则输出参数有效信号给第二计数单元280，第二计数加1，若不位于第二预设参数范围内，则输出参数无效信号给第二计数单元280，第二计数不变，气压传感器为本领域的常规技术和元器件，在此不再赘述。
在应用上述的方案进行实际测试过程中发明人发现：由于空气中气流的扰动，可能会导致处于抽吸状态时瞬间的气压下降，导致第一参数信息到达第二预设参数范围，这个瞬间的气压下降持续时间很短，一般偶尔的一次，造成第二计数单元215误计数，可能误触发电子烟进入解锁状态，给用户的使用造成困扰。为了解决该问题，请结合参阅图34和图38，步骤触发进行第二计数具体包括：
S131:触发进行第三计时并触发进行第三计数；
其中，童锁控制电路200还包括第三计时单元212和第三计数单元213，第三计时单元212、第三计数单元213均与第二参数判断单元211连接，当第三计时单元212、第三计数单元213获取第一参数信息位于第二预设参数范围内时，也即第三计时单元212接收到参数有效信号时，第三计时单元212开始第三计时，第三计时单元212一直计时，直到进行复位置零，此后第三计时单元212停止计时；第三计数单元213接收到参数有效信号时，第三计数单元213开始第三计数，且此次也进行第三计数，此时第三计数为1。
S132:判断在第三预设时长内第三计数是否大于或等于第三预设数量；
其中，童锁控制电路200还包括第三计时计数判断单元214，第三计时计数判断单元214分别与第三计数单元213、第三计时单元212连接，当第三计时计数判断单元214判断第三计时单元212的计时时长在第三预设时长内，且第三计数单元213的第三计数大于或等于第三预设数量，则第三计时计数判断单元214输出第一计数信号。在本实施例中，第三预设时长一般为30ms-150ms，第三预设时长例如为30ms、40ms、50ms、60ms、70ms、80ms、90ms、100ms、110ms、120ms、130ms、140ms、150ms等，较佳为60ms-100ms。在本实施例中，第三预设数量为大于或等于2的整数，例如为2、3等。在本实施例中，第三预设数量大于或等于2，例如为2、3、4、5、6等。
在本实施例中，第三计时计数判断单元214与第三计时单元212、第三计数单元213实时电连接，当第三计时计数判断单元214获取第三计数到达第三预设数量且第三计时未到达第三预设时长时，第三计时计数判断单元214输出第一计数信号，或者第三计时计数判断单元214等第三计时到达第三预设时长时才输出第一计数信号。在本申请的其他实施例中，第三计时计数判断单元214与第三计时单元212、第三计数单元213连接，当第三计时单元212到达第三预设时长时第三计时单元212输出信号给第三计时计数判断单元214，第三计时计数判断单元214获取此时第三计数单元213的第三计数，然后判断第三计数是否大于或等于第三预设数量，若第三计数大于或等于第三预设数量，则第三计时计数判断单元214输出第一计数信号，若第三计数小于第三预设数量，则第三计时复位置零，第三计数置零。
S133:若判断结果为是，则触发进行第二计数。
其中，第三计时计数判断单元214与第二计数单元215连接。若第三计时计数判断单元214的判断结果为是，则第二计数单元215接收到第一计数信号，第二计数单元215被触发开始计数，此时第二计数单元215对本次也进行计数，也即此时第二计数为1。另外，在本实施例中，第二计时单元216也与第三计时计数判断单元214连接，第二计时单元216接收到第一计数信号，第二计时单元216被触发开始计时，第二计时从0开始计时。
在本实施例中，当此前第二计数单元215没有被触发开始计数，第二计时单元216没有被触发开始计时，若第三计时计数判断单元214的判断结果为否，也即第三计时计数判断单元214不输出第一计数信号，第二计数单元215维持原来不进行计数，第二计时单元216维持原来不进行计时；当此前第二计数单元215已被触发开始计数(也即第二计数至少为1)，第二计时单元216已被触发计时，若第三计时计数判断单元214的判断结果为否，则第二计数维持原来的计数，第二计数不增加，第二计时继续计时。
在本实施例中，当空气气流串扰导致电子烟气流通道内气压短时间变化时，由于气压降低的时长很短，从而不会符合在第三预设时长内第三计数大于或等于第三预设数量的条件，从而第二计数不会变化，从而不会将空气气流串扰误判为用户想要解锁的情况，可以防止电子烟误进入解锁状态，可以防止对用户的使用造成困扰，本实施例可以避免这种情况发生，提升了用户的使用体验。
在本实施例中，在整个第三预设时长电子烟处于抽吸状态，在第三预设时长的部分时长或者整个时长均属于重吸，则第二计时单元216进行计数。
为了判断电子烟是否处于抽吸状态，本实施例采用与现有技术一样，通过状态检测单元150直接判断电子烟是否处于抽吸状态、吹气状态。具体说来，第一参数信息包括当前电容值、当前频率值、当前计数值、当前电容变化量、当前频率变化量、当前计数变化量、当前电容值与基准电容值的比值、当前频率值与基准频率值的比值、当前计数值与基准计数值的比值、当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值，请结合参见图35和图38，在本实施例中，童锁控制方法还包括:
S171:接收第一参数信息；
S172:判断第一参数信息是否位于第一预设参数范围内；
S173：若判断结果为是，则输出电子烟由未抽吸状态转为抽吸状态的信息。
其中，状态检测单元150包括第一参数生成单元、第一参数判断单元，第一参数生成单元分别与第一参数判断单元、第二参数判断单元211连接，第一参数生成单元生成第一参数信息后，第一参数判断单元接收第一参数信息，第一参数判断单元判断第一参数信息是否位于第一预设参数范围内，若判断结果为是，则第一参数判断单元输出电子烟由未抽吸状态转为抽吸状态的信息，也即输出抽吸信号，若判断结果为否，则第一参数判断单元维持原来的信号输出，例如输出未吸吹信号、吹气信号。进一步的，还可以要求连续多次判断为是，才输出抽吸信号，这样有利于降低气流串扰误触发的几率。在本实施例中，第一参数判断单元、第二参数判断单元211可以为同一个参数判断单元，也可以为不同的参数判断单元。
另外，在本申请的其他实施例中，第一参数信息包括当前气压值、当前气压变化量、当前气压值与基准气压值的比值、当前气压变化量与基准气压值的比值，童锁控制电路200包括第一参数判断单元，第一参数判断单元与气压获取单元连接，气压获取单元输出当前气压值、当前气压变化量、当前气压值与基准气压值的比值、当前气压变化量与基准气压值的比值后，第一参数判断单元接收当前气压值、当前气压变化量、当前气压值与基准气压值的比值、当前气压变化量与基准气压值的比值，第一参数判断单元判断当前气压值、当前气压变化量、当前气压值与基准气压值的比值、当前气压变化量与基准气压值的比值是否位于第一预设参数范围内，若判断结果为是，则第一参数判断单元输出电子烟由未抽吸状态转为抽吸状态的信息，也即输出抽吸信号，若判断结果为否，则第一参数判断单元维持原来的信号输出，例如输出未吸吹信号、吹气信号。在本实施例中，第一参数判断单元与童锁控制单元240连接，具体与童锁控制单元240的开关控制单元连接。进一步的，还可以要求连续多次判断为是，才输出抽吸信号，这样有利于降低气流串扰误触发的几率。另外，在本申请的其他实施例中，同样可以通过当前气压值或者当前气压变化量判断电子烟是否处于吹气状态，例如当前气压值或者当前气压变化量位于第四预设参数范围内时，此时电子烟处于吹气状态，输出吹气信号。在本实施例中，第一参数判断单元与第二参数判断单元可以是同一个判断单元，也可以是不同的判断单元。
在本实施例中，为了降低电子烟处于未抽吸状态时的功耗，步骤接收第一参数信息具体包括：获取电子烟由未抽吸状态转为抽吸状态的信息；
触发接收第一参数信息。
其中，第二参数判断单元211与状态检测单元150或者气压获取单元连接，第二参数判断单元211在未收到抽吸信号前不工作，当第二参数判断单元211在接收到抽吸信号后，第二参数判断单元211被触发开始工作。这样设置，有利于降低电子烟的功耗。
另外，在本实施例中，请结合参阅图36和图38，在步骤触发进行第二计数之后还包括：
S161:获取电子烟由抽吸状态进入未抽吸状态的信息；
S162:触发第五计时且对第二计数进行锁定；
S163:判断第五计时是否大于或等于第五预设时长；
S164:若判断结果为是，则解除对第二计数的锁定。
本实施例还对两次重吸之间的间隔时长进行规定，防止抽吸状态时气流抖动、串扰等而导致误第二计数。具体而言，在本实施例中，童锁控制电路200包括第五计时单元221和第五时长判断单元222，第五计时单元221分别与状态检测单元150、第三计时计数判断单元214连接，第五时长判断单元222分别与第五计时单元221、第二计数单元215电连接，第二计数单元215还与状态检测单元150电连接。当第三计时计数判断单元214输出第一计数信号后，第五计时单元221收到第一计数信号后又获取电子烟由抽吸状态进入未抽吸状态的信息，第五计时单元221被触发开始计时，同时第二计数单元215也在接收第一计数信号后又获取电子烟由抽吸状态进入未抽吸状态的信息，第二计数单元215被锁定，也即进入计数锁定状态，第二计数单元215被锁定后即使再接收到第一计数信号也不会进行计数增加，也即在锁定状态第二计数单元215保持原来的计数值，不会增加计数值，只有被解除锁定后处于计数解锁状态第二计数单元215收到第一计数信号才会计数加一。在本实施例中，当第五计时单元221开始第五计时后，第五计时单元221一直在计时(即使由未抽吸状态转为抽吸状态也在计时)，第五时长判断单元222判断第五计时单元221的计时时长是否大于或等于第五预设时长，当第五时长判断单元222判断第五计时单元221计时到达第五预设时长，第五计时单元221会停止计时并置零，也即第五计时单元221复位置零，同时，第五时长判断元输出计数解锁信号给第二计数单元215，第二计数单元215被解除对计数的锁定，第二计数单元215进入计数解锁状态，而且第三计时单元212、第三计数单元213、第二计时单元216也复位置零，此后第二计数单元215再次获取第一计数信号，第二计数单元215可以执行计数加一动作，也即第二计数在原来的基础上加一。在此实施例中，当第五计时单元221没有收到第一计数信号，或者第五计时单元221没有获取电子烟由抽吸状态进入未抽吸状态的信息，第五计时单元221也不会触发开始计时。在本实施例中，第五预设时长例如为50ms-150ms，例如为50ms、60ms、70ms、80ms、90ms、100ms、110ms、120ms、130ms、140ms、150ms等。
在本实施例中，在步骤触发进行第二计数之后还包括：判断第一参数信息位于第二预设参数范围内持续的时长是否大于或等于第七预设时长，若判断结果为是，则第二计数、第二计时均复位置零。本实施例中对重吸持续的时长进行判断，若重吸持续的时长大于或等于第七预设时长，则第二计数、第二计时均复位置零，第二计数为0，第二计时停止计时并置零，这样设置可以防止用户比较长时间抽吸后误动作进入童锁锁定状态，符合用户的使用预期。在本实施例中，第七预设时长大于或等于400ms，例如为400ms、450ms、500ms、600ms等。
在本实施例中，电子烟进入解锁状态后，用户可以正常抽吸电子烟，当用户不使用时，为了安全需要锁定电子烟时，此时需要对电子烟进行加锁，以下描述电子烟如何进行加锁，以下描述的仅是电子烟一种进入锁定状态的方式，本领域的技术人员还可以通过其他常规的方式使电子烟进入童锁锁定状态。另外，在本申请的其他实施例中，加锁方式可以与解锁方式一样，可以参见前面的描述，在此不再赘述。
请结合参阅图37和图38，在本实施例中，童锁控制方法还包括：
S21：接收第一参数信息；
其中，童锁控制电路200包括第四参数判断单元231，第四参数判断单元231用于接收第一参数信息，其中，第四参数判断单元231与第二参数判断单元211可以为不同的判断单元，也可以为同一参数判断单元。
在本实施例中，当处于吹气状态时，气流通道中气压较大，会高于未吸吹状态的气压，也即当前气压值会大于基准气压值，气流传感器140的电容的两个电极的间距相对未吸吹状态时要大，从而当前电容值会比未吸吹状态时小，当前频率值会比未吸吹状态时大，当前计数值会大于基准计数值。
S22:判断第一参数信息是否位于第四预设参数范围内，所述第四预设参数范围用于判断电子烟是否处于吹气状态；
S23:若判断结果为是，则触发进行第四计时并触发进行第四计数；
其中，第四参数判断单元231在接收到第一参数信息后，第四参数判断单元231判断第 一参数信息是否位于第四预设参数范围内，第四预设参数范围为预先计算获得，或者预先存储在第四参数判断单元231中。
当第一参数信息为当前电容值、当前电容值与基准电容值的比值，此时第四预设参数范围对应为电容值范围或者比值范围，第四预设参数范围的上限值会小于第一预设参数范围对应的下限值，第四预设参数范围的下限值可以不设限，也可以根据需要设限。当第一参数信息为当前气压值、当前频率值、当前计数值、当前气压值与基准气压值的比值、当前频率值与基准频率值的比值或者当前计数值与基准计数值的比值时，此时第四预设参数范围对应为气压值值范围、频率值范围、计数值范围或者比值范围，第四预设参数范围的下限值会大于第一预设参数范围对应的上限值，第四预设参数范围的上限值可以不设限，也可以根据需要设限。当第一参数信息为当前气压变化量、当前电容变化量、当前频率变化量、当前计数变化量、当前气压变化量与基准气压值的比值、当前电容变化量与基准电容值的比值、当前频率变化量与基准频率值的比值或者当前计数变化量与基准计数值的比值，此时第四预设参数范围与第一预设参数范围的大小关系可以不做限定，两者范围可以相同，也可以不同。
其中，童锁控制电路200包括第四计时单元232和第四计数单元233，第四计时单元232与第四参数判断单元231电连接，第四计数单元233与第四参数判断单元231电连接，若第四参数判断单元231的判断结果为是，则第四参数判断单元231输出吹气信号，第四计时单元232被触发开始计时，第四计时单元232从0开始计时，第四计数单元233被触发开始计数，并将此次也进行计数，也即此时第四计数单元233的计数为1；若第四参数判断单元231的判断结果为否，则第四参数判断单元231不会输出吹气信号，第四计时单元232维持原先的状态，第四计数单元233维持原先的状态。在本实施例中，当第四计时单元232被触发开始计时后，第四计时单元232会一直在计时，直到第四计时单元232被复位置零，此后第四计时单元232停止计时。在本实施例中，吹气信号也会输出给童锁控制单元240。
在本实施例中，当第四计时单元232被触发计时、第四计数单元233被触发计数后，当第四参数判断单元231又接收到第一参数信息，并又一次判断第一参数信息位于第四预设参数范围内，则第四计数单元233的第四计数加1，此时第四计数为2，同时，第四计时单元232在持续进行第四计时。
S24：判断在第四预设时长内第四计数是否大于或等于第四预设数量，其中，第四预设数量大于或等于2；
其中，童锁控制电路200还包括第四计时计数判断单元234，第四计时计数判断单元234分别与第四计数单元233、第四计时单元232电连接，当第四计时计数判断单元234判断第四计时单元232的计时时长在第四预设时长内，且第四计数单元233计数大于或等于第四预设数量，第四计时计数判断单元234输出童锁锁定信号。在本实施例中，第四预设时长一般小于或等于5s，例如为1s、1.5s、1.8s、2s、2.3s、2.5s、2.8s、3s、4s、5s等，较佳为2s。在本实施例中，第四预设数量大于或等于2，例如为2、3、4、5、6等，较佳为3，第四预设数量一般小于或等于6次，方便用户操作。
