Description

一种防止儿童误吸电子烟的方法 技术领域
本发明涉及日用电子产品领域，尤其涉及一种防止儿童误吸电子烟的方法。
背景技术
电子烟包括电池杆和雾化器，电池杆包括提供电子烟工作电压的电池，雾化器包括电热丝和提供烟油给电热丝的储油机构，现有电子烟通过气流传感器感应用户吸气产生的气流，并结合内部处理电路实现吸烟状态的检测，在检测到吸烟状态时对其进行响应，具体为：控制模块控制电池给电热丝供电。电热丝加热从而雾化储油机构内的烟油，最终达到吸烟效果。
对于气流传感器，一般采用开关式咪头或者电容式咪头，感应气流变化就可以使电路工作，而这种电子烟常常会在儿童误拿当玩具进行吸食时，电子烟则进行工作产生烟雾，因而影响儿童的健康，存在安全隐患。此外，这种电子烟在外界有非吸食气流流动或者温度等环境因素影响的情况下可能会发生误触发，导致电子烟发生错误的感应。

具体实施方式
实施本发明的防止儿童误吸电子烟的方法，通过增加锁定状态，在电子烟处于锁定状态时，控制模块始终控制电池断开给雾化组件的供电，所以即使儿童误吸电子烟、非吸食气流流动触发了吸烟开关或者用户误开启了吸烟开关，电子烟都不会对其进行任何响应。用户如果要正常吸烟，则必须首先开启解锁开关，使电子烟从锁定状态切换到正常工作状态。因此，利用本发明的方法，电子烟被儿童误吸或误触发的可能性大大降低。 同时，本发明的电子烟还可以在用户长时间没有吸烟时，自动进入锁定状态，在自动便利的同时，节省能耗。
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
参考图1是本发明一种防止儿童误吸电子烟的方法的第一实施例的流程图；同时结合图2是本发明一种防止儿童误吸电子烟的方法的第一实施例中的电子烟的结构框图；
首先参考图2，所述电子烟包括所述电子烟包括用于雾化烟油的雾化组件2、用于为所述雾化组件1供电的电池1、用于发送吸烟信号的吸烟开关4、控制模块3、用于发送解锁信号使所述电子烟从锁定状态进入正常工作状态的解锁开关5，所述电池1、雾化组件2、吸烟开关4、解锁开关5分别连接至所述控制模块3。
第一实施例中，所述方法包括：
S0、等待解锁；
在所述电子烟处于所述锁定状态时，所述控制模块3始终控制所述电池1断开给雾化组件2的供电。
在该状态时，如果吸烟开关4发送吸烟信号，控制模块3并不会控制电池1给雾化组件2供电。用户如果需要吸烟，则必须首先开启所述解锁开关5，一旦解锁开关5开启，立即进入步骤S1。
S1、所述控制模块3接收到所述解锁信号并控制所述电子烟进入正常工作状态。
电子烟一旦进入正常工作状态，则控制模块3会自动屏蔽掉解锁开关5发送的解锁信号，即解锁信号仅仅在电子烟处于锁定状态时才有效，其他时刻直接被屏蔽掉。值得注意的是，此处仅仅是屏蔽掉解锁信号，但是后续第三实施例中会提到解锁开关5发送的其他信号（第一设置信号和第二设置信号），并不会屏蔽掉。
S2、进行计时；
S3、控制模块3判断其在第一预设时间之内是否接收到所述吸烟信号？是，进入步骤S5；否则，控制模块3控制所述电子烟进入锁定状态，转步骤S0。
S4、所述电子烟进行雾化工作：所述控制模块3控制所述电池1给所述雾化组件2供电；并在本次吸烟信号发送完毕后转步骤S2。
其中，步骤S0中，解锁开关5的开启可以是普通的按键开关的开启，本发明中优选的，所述解锁开关5包括至少一个用于感应触摸动作的触摸按键和用于发送所述解锁信号的电容式触摸感应集成芯片；每一所述触摸按键分别连接至所述电容式触摸感应集成芯片的对应的触摸输入端口，所述电容式触摸感应集成芯片的输出端口分别连接至所述控制模块3。
对应的，所述步骤S0中，开启所述解锁开关5包括：用户输入的触摸动作所形成的触摸路径与预设触摸路径相同。本实施例中，关于触摸路径定义为：第二预设时间之内所输入的触摸动作的数量或者先后顺序形成所述触摸路径。预设触摸路径、第一预设时间和第二预设时间在电子烟出厂时厂家就已经将其写在了控制模块3的软件内进行保存，当然其也可以被用户更改，具体在后面的第三实施例中将做详细说明。
限定必须是第二预设时间之内是考虑到如果不限定时间，则会导致输入的触摸动作被误累积，比如，如果有编号为1、2、3的3个触摸按键，预设触摸路径是：依次触摸1、2、3，如果用户第一次是依次输入1、2，然后没有再输入了，如果不限定第二预设时间之内，则控制模块3会一直等待用户输入后续的触摸动作。所以如果隔了一段时间之后，用户第二次输入1、2、3，则控制模块3会将第二次输入的触摸动作加入第一次的触摸动作内，也就是说本来用户第二次输入正确，应该开启解锁开关5，但是控制模块3判断用户输入的是1、2、1、2、3，所以在用户第二次输入1时，则认为用户输入错误。
其中，电子烟在步骤S2中切换到自动锁定的情况有两种：
一是，用户开启解锁开关5后，如果第一预设时间之内没有开启吸烟开关4，即没有给予吸烟信号，则电子烟将从正常工作状态再次切换到锁定状态；如果第一预设时间之内开启了吸烟开关4，则进入步骤S4，对吸烟信号进行常规的响应；
二是，用户开启解锁5开关后，吸烟开关4至少开启了一次，也即本次计时是从步骤S4跳转过来的，如果自上次吸烟开关4发送吸烟信号完毕之后的预设时间内用户没有开启吸烟开关4，则电子烟将从正常工作状态再次切换到锁定状态，而如果再次开启吸烟开关4且距离上次吸烟信号发送完毕的时间在预设时间之内，则再次进入步骤S4，对吸烟信号进行常规的响应。
下面结合电子烟的具体电路结构详细阐述本方法的过程；
参考图3是图2中的电子烟的第一实施方式的电路图；
第一实施例的第一实施方式中，电容式触摸感应集成芯片为型号为AR101的单通道电容式触摸感应集成芯片 U2，因此其仅能有效监测一个触摸按键，对应的触摸路径是：触摸该触摸按键。
所述雾化组件2包括电热丝B1，所述控制模块3包括型号为SN8P2711B的微处理器U1、N型的MOS管Q1，所述吸烟开关4为气流传感器M1，所述电子烟还包括第二LED灯LED2。
MOS管Q1的源极连接至所述电池1的负极， MOS管Q1的漏极通过所述电热丝B1连接至所述电池1的正极， MOS管Q1的栅极连接至所述微处理器U1的P5.3引脚，MOS管Q1的栅极还通过电阻R2连接至MOS管Q1的源极；气流传感器M1的信号输出端连接至所述微处理器U1的P0.2引脚，气流传感器M1的电源端和接地端分别对应连接至电池1的正极和负极。微处理器U1的VDD引脚经电容C0接地，VDD引脚还连接至二极管D1的负极，二极管D1的正极连接至电池1正极。第二LED灯LED2的正极连接至电池1正极，第二LED灯LED2的负极通过电阻R1连接至微处理器U1的P5.4引脚。微处理器U1的VSS引脚接地。
单通道电容式触摸感应集成芯片U2的out引脚连接至微处理器U1的P4.0引脚，out引脚用以输出解锁信号，touch引脚连接至第一触摸按键PAD1。vdd引脚和op2引脚并联后经电阻R3连接至电池1正极，因此，out输出为保持模式，vdd引脚还经滤波电容C2接地，op1引脚和VSS引脚接地，因此out输出为高电平有效。
步骤S0中：
电子烟处于锁定状态时，微处理器U1的P5.3引脚始终输出低电平，因此MOS管Q1保持截止。此时无论微处理器U1的P0.2引脚是否接收来自气流传感器M1的电压信号，P5.3引脚均不会输出高电平。微处理器U1的P5.4引脚保持输出高电平，第二LED灯LED2不亮灯。
如果用户触摸第一触摸按键PAD1，则U2的out引脚输出的解锁信号为：输出电平改变。
步骤S1中：微处理器U1的P4.0接收到变化的电平后控制电子烟进入正常工作状态。
步骤S2中：计时可以利用与微处理器U1分离的计时器实现，本实施例中优选的直接利用微处理器U1内部的定时器TC0或者TC1实现计时。
如果用户吸气，气流传感器M1的信号输出端输出电压信号作为吸烟信号并发送至微处理器U1的P0.2引脚。
步骤S4中：微处理器U1的P5.3引脚输出高电平，MOS管Q1导通，所述电池与电热丝B1的电连接导通，电热丝B1发热实现雾化烟油。同时，微处理器U1的P5.4引脚输出低电平，所述第二LED灯LED2导通发光以指示所述电子烟处于吸烟状态。
其中，控制MOS管Q1导通实际上是导通一段时间，过后恢复控制MOS管Q1的截止。进入步骤S2中重新计时的时刻，可以是P0.2引脚接收吸烟信号完毕的时刻，也可以是MOS管Q1导通完毕的时刻。
图4是图2中的电子烟的第二实施方式的电路图；
第二实施方式与第一实施方式的不同在于解锁开关5不同。第二实施方式中所述电容式触摸感应集成芯片为型号为JG602的两通道电容式触摸感应集成芯片U3，所述触摸按键包括第一触摸按键PAD1和第二触摸按键PAD2。
所述两通道电容式触摸感应集成芯片U3的TP0引脚和TP1引脚分别一一对应连接至第一触摸按键PAD1和第二触摸按键PAD2，TP0引脚和TP1引脚还分别经滤波电容C3和滤波电容C2接地，所述两通道电容式触摸感应集成芯片U3的AHLB引脚和TOG引脚均悬空，因此有效输出为高电平，且输出电平不锁定，所述两通道电容式触摸感应集成芯片U3的VDD引脚和VSS 引脚分别一一对应连接至所述电池1的正极和负极，VDD引脚还经滤波电容C1接地，所述两通道电容式触摸感应集成芯片U3的TPQ0引脚和TPQ1引脚分别一一对应连接至所述微处理器U1的P4.4引脚和P4.0引脚。
如果第一触摸按键PAD1被触摸，则TP0引脚输出高电平，如果第二触摸按键PAD2被触摸，则TP1引脚输出高电平。TP0引脚和TP1引脚输出的电平信号发送至微处理器U1的P4.4引脚和P4.0，因此，微处理器U1根据接收到的电平信号判断触摸路径是否为预设触摸路径。
根据之前所述触摸路径定义为：第二预设时间之内所输入的触摸动作的数量或者先后顺序形成所述触摸路径。下面提供几种具体的触摸路径的定义和预设触摸路径的设置：
例如，所述第二预设时间之内所输入的触摸动作的先后顺序形成所述触摸路径。对应这种情况下，预设触摸路径的设置有：
首先触摸所述第一触摸按键PAD1，然后触摸所述第二触摸按键PAD2，对应的所述解锁信号为TPQ0引脚和TPQ1引脚先后输出高电平；
或者，首先触摸所述第二触摸按键PAD2，然后触摸所述第一触摸按键PAD1，对应的所述解锁信号为TPQ1引脚和TPQ0引脚先后输出高电平。
再例如，所述第二预设时间之内所输入的触摸动作的数量形成所述触摸路径，所述预设触摸路径为：所述第二预设时间之内无序的触摸所述第一触摸按键PAD1和第二触摸按键PAD2，所述解锁信号为TPQ1引脚和TPQ0引脚在所述第二预设时间之内输出高电平。即，此时只有保证在第二预设时间之内两个触摸按键均被触摸即解锁，与触摸的先后顺序无关，仅与被触摸的触摸按键的数量有关。
需明确的是，触摸路径除了以上方式，还可以是触摸按键数量结合顺序的排列组合，比如先触摸第一触摸按键PAD1两次，在触摸第二触摸按键PAD2一次，再触摸第一触摸按键PAD1一次，只要是利用触摸按键的组合和顺序形成的即可。且触摸按键的个数以及电容式触摸感应集成芯片的选择在并不限于以上的方式，例如四通道电容式触摸感应集成芯片、六通道电容式触摸感应集成芯片等等。电容式触摸感应集成芯片还可以用电阻式触摸感应集成芯片、普通按键开关等替换。
进一步需明确的是，本实施例中触摸按键的布局并不做限制，例如可以是在电子烟外壁上平行于电子烟轴向直线设置，或者在电子烟周向侧壁上相对位置设置。
图5是本发明一种防止儿童误吸电子烟的方法的第二实施例的流程图；结合图6是本发明一种防止儿童误吸电子烟的方法的第二实施例中的电子烟的结构框图；
第二实施例与第一实施例相比，电子烟增加了提醒模块6，提醒模块6连接至所述控制模块3。
在所述步骤S0中，若开启所述吸烟开关4，则进入步骤S5；
S5、所述控制模块3接收到所述吸烟信号，并控制所述提醒模块6进行发光或者发声以提醒用户开启所述解锁开关5。
具体的，参考图7是图6中的电子烟的较佳实施方式的电路图。
与上述第一实施例的第二实施方式相比，增加了所述提醒模块6，其包括第一LED灯LED1。
在步骤S5中，所述第一LED灯LED1通过闪烁发光提醒用户开启所述解锁开关5；
且，所述步骤S0中还包括：第一LED灯LED1常亮或者熄灭以指示所述电子烟处于锁定状态；相应的，所述步骤S1中还包括：第一LED灯LED1熄灭或者常亮以指示所述电子烟处于正常工作状态。
按照生活中的习惯，一般用亮灯指示有效，因此优选的，第一LED灯LED1熄灭以指示所述电子烟处于锁定状态，第一LED灯LED1常亮以指示所述电子烟处于正常工作状态。
为了提高电子烟的用户体验感，上述的第一预设时间以及预设触摸路径的设置可以由用户进行重新设定。例如某些用户觉得出厂设定的第一预设时间过短，希望可以延长“待机”时间，或者用户觉得出厂设定的预设触摸路径过于简单呆板，希望设置一个比较有个性的开启解锁开关的方式，或者希望设置一个只有自己才能开启解锁开关5的方式，以避免为他人随意使用自己的电子烟等等。
下面参考图8是详细介绍本实施例的方法。
本实施例与上述第二实施例的不同在于：在所述步骤S2计时的过程中，可以进行以下更改设置功能：如果控制模块3接收到第一设置信号，则转步骤S6，如果控制模块3接收到第二设置信号，则转步骤S7：
S6、清零计时，重新设置第一预设时间，并转步骤S2。
S7、清零计时，重新设置预设触摸路径，并转步骤S2。
启动重新设置的功能，必须在电子烟解锁的状态下执行，即在计时的过程中，如此可以防止他人随意更改设置。可以由专门的设置开关实现启动该功能，本发明中为了节省元器件，该功能由解锁开关5实现。利用上述第二实施例的较佳实施方式中的电子烟的结构，本实施例中长按第一触摸按键PAD1时，TP0引脚输出的对应的长时间的电平信号为第一设置信号，长按第二触摸按键PAD2时，TP1引脚输出的对应的长时间的电平信号为第二设置信号。
需要明确的是，第一设置信号和第二设置信号的定义在本发明中并不做限定，例如还可以是同时长按两个触摸按键时，TP0引脚和TP1引脚输出的长时间的电平信号为第一设置信号或第二设置信号。
其中，步骤S6具体包括：
S61、清零计时，控制模块3等待解锁开关5输入时间；等待输入的时间可以根据需求在出厂的时候确定好，比如等待5s，如果用户没有输入则默认取消设置，并直接跳回步骤S2；
S62、解锁开关5输入时间，控制模块3将本次输入时间保存为第一预设时间，清零计时，转步骤S2。
时间的输入可以通过计数触摸按键被触摸的次数实现，每次进入设置功能时，以上次保存的第一预设时间作为基准进行增加或者减少，比如触摸一次第一触摸按键PAD1，则代表增加3s，触摸一次第二触摸按键PAD2则代表减少3s。设置完毕后，还可以通过再次输出与第一设置信号相同的信号作为设定完毕并保存的指示信号。
其中，步骤S7具体包括：
S71、控制模块3等待解锁开关5输入触摸路径，此处的详细说明与上述步骤S61相同。
S72、解锁开关5输入触摸路径，控制模块3将本次输入的触摸路径保存为预设触摸路径，清零计时，转步骤S2。
S72与上述步骤S62类似，值得注意的是，用户如果想设定触摸动作的数量形成所述触摸路径，即预设触摸路径为触摸按键被触摸的数量，则必须保持在某个时刻同时触摸要设定的数量的触摸按键，比如，对于有6个触摸按键的，出厂设置时的预设触摸路径为同时触摸6个触摸按键，但是用户觉得太过麻烦，想设定为同时触摸两个触摸按键来开启解锁开关使其发送解锁信号，则在启动该设置功能后，用户输入触摸路径时要保持同时触摸两个触摸按键。如果用户是先后触摸了该两个触摸按键，将会被认为设置的预设触摸路径是按照先后顺序设置的。而对于一个触摸按键的情况，按照数量与按照顺序形成触摸路径的方法是一样的效果。
优选的，在用户设置完毕并确定保存后，用户需要再次输入之前输入的内容，以确保用户已经记住输入的内容。
同理，还可以对第二预设时间进行重新设置，设置方法类似，参见上述第一预设时间的设置，此处不再赘述。
综上所述，本发明的防止儿童误吸电子烟的方法，通过增加锁定状态，在电子烟处于锁定状态时，控制模块始终控制电池断开给雾化组件的供电，所以即使儿童误吸、非吸食气流流动触发了吸烟开关或者用户误开启了吸烟开关，电子烟都不会对其进行任何响应。用户如果要正常吸烟，则必须首先开启解锁开关，使电子烟从锁定状态切换到正常工作状态。因此，利用本发明的方法，电子烟被儿童误吸或误触发的可能性大大降低。 同时，本发明的电子烟还可以在用户长时间没有吸烟时，自动进入锁定状态，在自动便利的同时，节省能耗。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护之内。
