雾化器组件、限定寿命的电子烟及限定电子烟寿命的方法 技术领域
本发明涉及电子烟技术领域，尤其涉及一种雾化器组件、限定寿命的电子烟及限定电子烟寿命的方法。
背景技术
电子烟是一种较为常见的仿真香烟电子产品，主要用于戒烟和替代香烟；电子烟的结构主要包括电池组件和雾化器组件；当检测到吸烟者的吸烟动作时，电池组件为雾化器组件供电，使雾化器组件处于开启状态；当雾化器组件开启后，发热丝发热，烟液受热蒸发雾化，形成模拟烟气的气雾，从而让使用者在吸时有一种类似吸烟的感觉。
早期，许多雾化器组件未有寿命（如吸烟口数）限制，只要接上电池组件给雾化器组件供电，雾化器组件就能接通工作，在使用前段时烟液充足，因而烟气口感纯正，但是到使用后段时，由于烟液变少会导致烟雾量减少，甚至出现烧棉异味的情况，从而给用户带来很不好的体验。
目前，针对上述问题，有相关文献提出对电子烟的结构进行改进，在电池组件内加入控制单元，用于对吸烟口数进行统计，并在吸烟口数达到预设值时断开雾化器组件，以避免烟液变少导致烟雾量减少和烧焦的现象；但是，在现有方案中，电子烟只要收到吸烟信号（如按键触发形成的吸烟信号），控制单元就开始统计吸烟口数，同时减少剩余的可用口数；然而，在实际使用过程中，雾化器组件可能存在与电池组件断开的情况，如雾化器组件出现松动与电池组件断开或电池组件单独放置而未与雾化器组件相连等，此时控制单元与电池仍处于连通状态，当用户误操作（如不小心碰到吸烟触发按键或小孩儿玩耍向电子烟发出吸烟动作等）触发产生吸烟信号时，控制单元仍然会进行吸烟口数统计，并减少电子烟的可用吸烟次数，而实际上雾化器组件并没有启动，也未消耗烟液；如此便造成可用的吸烟口数白白减少，即出现当控制单元中统计的吸烟口数达到预设值，且电子烟不可用时，电子烟中还残留可利用的烟液。
也就是说，现有技术中存在电子烟在进行吸烟口数限制时无法准确统计吸烟口数，而造成电子烟产品一致性差的技术问题。

具体实施方式
本发明实施例通过提供一种雾化器组件，解决了现有技术中电子烟在进行吸烟口数限制时无法准确统计吸烟口数，而造成电子烟产品一致性差的技术问题，实现了准确统计吸烟口数，有效保证产品一致性的技术效果。
本发明实施例的技术方案为解决上述技术问题，总体思路如下：
本发明实施例提供了一种雾化器组件 ，用于与电池组件组合形成电子烟，所述 雾化器组件 包括：用于与所述电池组件可拆卸连接的接口电路，与所述接口电路连接的雾化电路和主电路；所述主电路用于在通过所述接口电路与所述电池组件电连通后，根据所述雾化电路的实际导通次数统计吸烟口数，以使所述电子烟在所述吸烟口数达到预设值时控制所述雾化电路断开并终止工作。
可见，在本发明实施例中，通过将用于统计吸烟口数的主电路设置在雾化器组件内部，使得当雾化器组件与电源断开时，基于吸烟口数控制雾化器通断的控制单元无法对存储在雾化器组件中的吸烟口数进行操作；进一步，所述主电路根据雾化电路的实际导通次数统计吸烟口数，使得当所述主电路与电池组件连通，而雾化电路断路（如发热电阻丝故障）时，所述控制单元同样无法对存储在雾化器组件中的吸烟口数进行操作，必须在确定雾化电路实际导通且加热电阻丝实际工作后才对吸烟口数进行统计，以供控制单元控制使用，有效地解决了现有技术中 电子烟在进行吸烟口数限制时无法准确统计吸烟口数，而造成电子烟产品一致性差的技术问题，实现了在进行吸烟口数限制时准确统计吸烟口数，有效保证产品一致性（即有效吸烟口数和烟液量匹配）的技术效果。
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明，应当理解本发明实施例以及实施例中的具体特征是对本申请技术方案的详细的说明，而不是对本申请技术方案的限定，在不冲突的情况下，本发明实施例以及实施例中的技术特征可以相互组合。
实施例一
请参考图 1A 和图 1B ，本发明实施例提供了一种雾化器组件 10 ，用于与电池组件 20 组合形成电子烟， 雾化器组件 10 包括：
用于与电池组件 20 可拆卸连接的接口电路 101 ，与接口电路 101 连接的雾化电路 102 和主电路 103 ；
主电路 103 用于在通过接口电路 101 与电池组件 20 电连通后，根据雾化电路 102 的实际导通次数统计吸烟口数，以使所述电子烟在所述吸烟口数达到预设值时控制雾化电路 102 断开并终止工作。
在本申请实施例中，电子烟的雾化器组件 10 和电池组件 20 可通过接口电路 101 进行可拆卸连接；具体的，请参考图 2A 和图 2B ，接口电路 101 包括：连接件 1011 和从连接件 1011 上引出的与雾化电路 102 和主电路 103 连接的多条连接线 1012 。如图 2A 所示，连接件 1011 为排座，在所述排座上设置有并排的排座孔 1011-1 ，对应的，电池组件 20 上设置与所述排座相匹配的排针，通过将所述排针插入或拔出所述排座孔 1011-1 ，以实现电池组件 20 和雾化器组件 10 的可拆卸连接；其中，排座孔 1011-1 的个数依据具体情况而定；例如，电池组件 20 主要通过接口电路 101 为雾化器组件 10 供电，那么排座孔 1011-1 包括电源和地两个孔。又如图 2B 所示，连接件 1011 为卡座，在所述卡座上设置有并排的接触点 1011-2 ，对应的，电池组件 20 上设置有与卡座接触点 1011-2 匹配的接触点，通过将电池组件 20 卡入或拔出所述卡座，以实现电池组件 20 和雾化器组件 10 的可拆卸连接，同样的，接触点 1011-2 的个数依据具体情况而定，这里不做具体限定。
在具体实施过程中，电池组件 20 包括用于检测用户吸烟动作的吸烟动作检测器，所述吸烟动作检测器可以是气流感应器或触摸开关等，在此不作具体限定；当吸烟动作检测器检测到用户吸烟动作后，且电池组件 20 通过接口电路 101 与雾化器组件 10 物理连接时，电池组件 20 通过接口电路 101 为主电路 103 供电。主电路 103 根据雾化电路 102 的实际导通次数统计吸烟口数，这里所说的'实际导通'是指雾化电路 102 从电池组件 20 获取到有效雾化烟油的电能；具体的，雾化电路 102 包括发热器件（如电阻丝），当雾化电路 102 实际导通并在雾化电路 102 无故障时，发热器件会发热，烟液受热蒸发雾化。进一步，电子烟根据所述吸烟口数控制雾化电路 102 ，并在所述吸烟口数达到预设值时控制雾化电路 102 断开并终止工作；另需指出的是，上述的预设值可以根据烟液成分、电子烟内烟液容积及每次吸烟的烟液损耗量的统计值进行设定，具体可以为 290 口或 300 口等，这里不作具体限定。
在具体实施过程中，主电路 103 用于根据雾化电路 102 的实际导通次数统计所述吸烟口数，并在与电池组件 20 电连通时，向电池组件 20 提供所述吸烟口数，以使电池组件 20 在所述吸烟口数达到所述预设值时控制雾化电路 102 断开并终止工作；主电路 103 或用于根据雾化电路 102 的实际导通次数统计所述吸烟口数并在所述吸烟口数达到所述预设值时直接控制雾化电路 102 断开并终止工作。也就是说，电子烟的用于控制雾化电路 102 通或断的控制器可设置在雾化器组件 10 内，也可设置在电池组件 20 内，下面对这两种情况分别进行介绍：
1 ）情况一：雾化电路 102 通断控制器设置在电池组件 20 内部，且吸烟口数存储器设置在雾化器组件 10 内部。
主电路 103 为：存储器集成电路，其通过接口电路 101 向电池组件 20 提供所述吸烟口数，以使所述电池组件在所述吸烟口数达到所述预设值时控制雾化电路 102 断开并终止工作。所述控制器同样通过接口电路 101 控制雾化电路 102 的通或断。
请参考图 3A ，雾化器组件 10 内部采用存储器集成电路（ IC ， integrated circuit ）存储吸烟口数等信息。作为存储数据用的 IC ，在此实施方式中，使用型号为 DS2431 的存储器芯片；另外，根据实际使用情况的不同，存储器集成电路还可以采用其他型号的存储器 IC ，如 ST24C02 等。在图 3A 中，存储器集成电路 DS2431 包括 6 个引脚（ 1-I/O 、 2-GND 、 3-NC 、 4-NC 、 5-NC 、 6-NC ），接口电路 101 的连接件 JP1 上设置有四个接线端（ 1~4 ），其中，连接件 JP1 的接线端 2 和接线端 1 分别与引脚 1-I/O 和引脚 2-GND 连接，接线端 3 和接线端 4 分别与雾化电路 102 中的发热电阻丝 R1 的两端连接。
其具体工作原理为：当电池组件 20 检测到用户吸烟动作后，且电池组件 20 通过接口电路 101 与雾化器组件 10 物理连接时，电池组件 20 中的控制器通过连接件 JP1 的接线端 2 与 DS2431 的数据输入输出引脚 1-I/O 进行通信，读取 DS2431 内部存储的剩余吸烟口数，并将所述吸烟口数与预设值进行比较，如若当前读取的剩余吸烟口数大于预设值（如 1 ），说明仍可继续吸烟，电池组件 20 通过连接件 JP1 的接线端（ 3 、 4 ）为电阻丝 R1 供电使其发热，如若当前读取的剩余吸烟口数小于或等于预设值，说明不可继续吸烟，电池组件 20 停止为电阻丝 R1 供电，进而使得雾化电路 102 与电源断开终止工作。在具体实施过程中，用户每吸一口烟，电池组件 20 中的控制器将雾化器组件 10 内部的存储器集成电路所存储的吸烟口数减一，然后更新存储器集成电路内的剩余吸烟口数；例如，存储器集成电路内预先存储有吸烟口数为 300 ，在用户抽烟时，电池组件 20 中的控制器从雾化器组件 10 的存储器 IC 中读取值 300 的吸烟口数，当抽一次烟后，控制器将 300 减一，变成 299 口，然后，再将此 299 口的数目写回雾化器组件 10 内的存储器 IC 中；此时的预设值可设置为 1 ，当控制器读取的吸烟口数大于等于 1 时，电池组件 10 为电阻丝 R1 供电，当读取的吸烟口数小于 1 时，电池组件 10 断开电阻丝 R1 供电线路。
当然，电池组件 20 从存储器 IC 中读取当前吸烟口数后，还可通过判断该吸烟口数是否小于等于预设值（如 299 ），如若当前读取的吸烟口数小于等于预设值，说明仍可继续吸烟，电池组件 20 通过连接件 JP1 的接线端（ 3 、 4 ）为电阻丝 R1 供电使其发热，如若当前读取的吸烟口数大于预设值，说明不可继续吸烟，电池组件 20 不为电阻丝 R1 供电，进而使得雾化电路 102 与电源断开终止工作。在具体实施过程中，用户每抽一次烟，电池组件 20 中的控制器将雾化器组件 10 内部的存储器 IC 所存储的吸烟口数加 1 ，然后更新存储器 IC 内的吸烟口数；例如，存储器 IC 内预先存储有吸烟口数为 0 ，在用户抽烟时，电池组件 20 中的控制器读取值 0 的吸烟口数，当抽一次烟后，控制器将 0 加一，变成 1 口，然后，再将此 1 口的数目写回雾化器组件 10 内部的存储器 IC 中；此时的预设值可设置为 299 ，当控制器读取的吸烟口数小于等于 299 时，电池组件 20 为电阻丝 R1 供电，当读取的吸烟口数大于 299 时，电池组件 10 不为电阻丝 R1 供电。
另外，所述存储器集成电路还可采用带非易失性存储器的单片机、 FPGA 等。具体的，以所述存储器集成电路为单片机 PIC12F519 为例进行说明：
如图 3B 所示，单片机 PIC12F519 包括 8 个引脚（ 1-VDD 、 2-RB5 、 3-RB4 、 4-RB3 、 5-RB2 、 6-RB1 、 7-RB0 、 GND ）；接口电路 101 的连接件 J1 上设置有三个接线端（ 1~3 ）；其中，连接件 J1 的接线端 3 通过二极管 D1 接单片机 PIC12F519 的电源管脚 1-VDD ；接线端 2 与单片机 PIC12F519 的引脚 2-RB5 连接；接线端 1 接地；接线端（ 1 ， 3 ）还分别与雾化电路 102 中的发热电阻丝 R1 的两端连接；电容 C1 的一端接二极管 D1 ，另一端接地。
其工作原理为：单片机的管脚 2-RB5 的作用是与电池组件 20 进行通讯，来决定电池组件 20 是否可以控制导通雾化电路 102 。单片机 PIC12F519 向电池组件 20 反馈的通讯内容可以为吸烟口数或通讯命令，其中，所述通讯命令具体为命令 1 （可以导通）和命令 2 （不可以导通）。在具体实施过程中，当电池组件 20 检测到用户吸烟动作后，且电池组件 20 通过接口电路 101 与雾化器组件 10 物理连接时，电池组件 20 通过连接件 J1 的接线端 3 （如图 3B 所示）向雾化器组件 10 中的单片机 PIC12F519 供电；具体的，电容 C1 通过二极管 D1 充电，充电后单片机 PIC12F519 就开始运行，单片机通过管脚 2-RB5 获取电池组件 20 的读取指令，当所述读取指令为要求单片机反馈吸烟口数时，则单片机仍通过管脚 2-RB5 将吸烟口数反馈给电池组件 20 ，以使电池组件 20 基于当前读取的吸烟口数与预设值进行比较（具体如何比较，同上述图 3A 所示方案，这里不再一一赘述），判断雾化器组件 10 是否能够继续工作（即用户是否能够继续吸烟），当判断结果为否时，则停止为雾化器组件 10 供电，当判断结果为是时，则继续为雾化器组件 10 供电（具体为电阻丝 R1 供电）；当所述读取指令为要求单片机反馈所述通讯命令时，单片机则读取内部存储的吸烟口数，并基于当前读取的吸烟口数与预设值进行比较，判断雾化器组件 10 是否能够继续工作，当判断结果为是时，将表示'可以导通雾化电路 102' 的所述命令 1 反馈给电池组件 20 ，以使电池组件 20 能够继续为雾化器组件 10 供电，当判断结果为否时，将表示'不可以导通雾化电路 102' 的所述命令 2 反馈给电池组件 20 ，以使电池组件 20 停止供电。另外，对于此次吸烟后，存储在单片机 PIC12F519 中的吸烟口数的加或减的处理方式也同上述图 3A 所示方案。
这里需要指出的是，在图 3B 中，在电池组件 20 通过连接件 J1 为单片机 PIC12F519 供电时，同时也在为发热电阻丝 R1 供电，但是这与本发明方案没有冲突，因为电池组件 20 为单片机 PIC12F519 供电，并获得用于控制雾化电路 102 是否导通的控制指令，耗时很短，不至于使电阻丝 R1 的温度上升到能够使烟液发生雾化的温度水平，或者，即使烟液发生少量雾化，也是较短的时间，因而不能有效雾化烟油；因此，即使电池组件 20 最终获得的结论为不导通雾化电路 102 （即无法供用户吸烟），也不会出现烧焦等不良后果。
2 ）情况二：雾化电路 102 通断控制器和吸烟口数存储器均设置在雾化器组件 10 内部。
A 、控制器功能和存储器功能通过一块芯片实现
具体的，请参考图 4 ，主电路 103 包括：内置有非易失性存储器 1031-1 的处理芯片 1031 ；非易失性存储器 1031-1 用于根据雾化电路 102 的实际导通次数统计所述吸烟口数。处理芯片 1031 还包括：与雾化电路 102 连接的控制模块 1031-2 ，用于在通过接口电路 101 与电池组件 20 电连通后，从非易失性存储器 1031-1 获取所述吸烟口数，并在所述吸烟口数达到所述预设值时控制雾化电路 102 断开。 雾化电路 102 包括：开关件 1021 ；其中，所述电子烟在所述吸烟口数达到预设值时控制开关件 1021 断开，以实现雾化电路 102 的断开；具体可通过控制模块 1031-2 对开关件 1021 进行控制。
在具体实施过程中，请参考图 5 ，处理芯片 1031 采用带有 FLASH 存储器（即非易失性存储器 1031-1 ）的单片机 PIC12F519 ，吸烟口数值可以存储在 FLASH 中或者程序 ROM 中；接口电路 101 的连接件 J1 设置有两个接线端（ 1 、 2 ）， 1 端接地、 2 端通过一个二极管 D1 接单片机 PIC12F519 的电源管脚 1-VDD ；电容 C1 的一端接二极管 D1 ，另一端接地；开关件 1021 采用 MOSFET 开关管 Q1 ，其源极与单片机 PIC12F519 的引脚 5-RB2 连接；电阻 R12 为设置在开关管 Q1 栅极和源极之间的泄放电阻；发热电阻丝 R1 的一端与连接件 J1 的接线端 2 连接，另一端通过开关管 Q1 与地连接（即与连接件 J1 的接线端 1 连接）。
其工作原理为：当电池组件 20 检测到用户吸烟动作后，且电池组件 20 通过接口电路 101 与雾化器组件 10 物理连接时，电池组件 20 通过连接件 J1 的接线端（ 1 ， 2 ）向雾化器组件 10 中的模块供电，具体的，电容 C1 通过二极管 D1 充电，充电后单片机 PIC12F519 就开始运行，此时开关管 Q1 是截止的，所以，雾化器电阻丝 R1 是不导通的；单片机 PIC12F519 运行起来后，单片机 PIC12F519 内部的逻辑控制模块（即图 4 中的控制模块 1031-2 ，在图 5 中未画出）检查存储在 FLASH 中或者程序 ROM 中的吸烟口数，并将所述吸烟口数与预设值进行比较（具体如何比较同上述图 3A 所示方案，这里不再一一赘述），当比较结果表明仍可继续吸时，单片机 PIC12F519 将通过管脚 5-RB2 输出 HIGH 高电平，以使开关管 Q1 导通工作，电阻丝 R1 与电源接通，吸烟正常进行；当比较结果表明不可继续吸时，单片机 PIC12F519 将通过管脚 5-RB2 输出 LOW 低电平，以使开关管 Q1 无法导通，加热电阻丝 R1 与电源断开无法工作。其中，对于此次吸烟后，存储在 FLASH 中或者程序 ROM 中的吸烟口数的加或减的处理方式也同上述如图 3A 所示的方案。
B 、控制器功能和存储器功能分别通过不同的芯片实现
具体的，请参考图 6 ，主电路 103 包括：外部存储器 1032 ，用于根据雾化电路 102 的实际导通次数统计所述吸烟口数；与外部存储器 1032 和雾化电路 102 连接的控制芯片 1033 （不包含非易失性存储器），用于在通过接口电路 101 与电池组件 20 电连通后，从外部存储器 1032 获取所述吸烟口数，并在所述吸烟口数达到所述预设值时控制雾化电路 102 断开。
请参考图 7 ，在本实施例中，当选用的控制芯片 1033 不包含非易失性存储器，可以在控制芯片 1033 外部增设一个与其相连的外部存储器 1032 ，如 DS2431 ， ST34C02 等型号的非易失性存储器。由图 7 可知，控制芯片 1033 的外围电路基本同上述实施例（如图 5 所示）中单片机 PIC12F519 的外围电路；当然，控制芯片 1033 与外部存储器 1032 （如 DS2431 ）的管脚连接，要根据所选用的控制芯片 1033 的类型来定，具体可参照控制芯片 1033 和外部存储器 1032 的应用手册，这里不作具体限定。其工作原理同上述图 5 所示的方案，这里的外部存储器 1032 的功能相当于上述非易失性存储器 1031-1 的功能，控制芯片 1033 的功能相当于上述控制模块 1031-1 的功能，故不再一一赘述。
进一步，在具体实施过程中，为了能够准确判断雾化电路 102 是否实际导通，且发热电阻丝 R1 是否实际进行有效雾化烟油，进而使统计的吸烟口数更加准确，可通过温度检测和电流检测两种方案来确定雾化电路 102 是否实际导通，以及发热电阻丝 R1 是否实际进行有效雾化烟油：
（ 1 ）温度检测方案：请参考图 8A ， 雾化器组件 10 还包括：与雾化电路 102 和主电路 103 连接的温度检测电路 104 ，用于在 主电路 103 与电池组件 20 电连通后，检测雾化电路 102 的发热器件的温度信号，并基于所述温度信号向主电路 103 反馈雾化电路 102 的实际导通情况。
具体的，请参考图 8B ，为基于温度传感器 DS18B20 的温度检测电路原理图，如图 8B 所示，温度传感器 DS18B20 包括三个管脚（ 1-GND 、 2-I/O 、 3-VCC ）；其中，管脚 1-GND 用于接地；管脚 2-I/O 用于与主电路 103 连接，向主电路 103 输出温度信号；管脚 3-VCC 接电源 VCC ；电阻 R3 为外围电路电阻。该电路紧贴雾化电路 102 中的发热器件安装，当所述发热器件温度变化时， DS18B20 输出引脚 2-I/O 输出相应的温度信号，并通过 OUT 端送入主电路 103 ，以使主电路 103 基于所述温度信号判断其是否达到烟液雾化的温度水平；当判断结果为是时，则确定雾化电路 102 实际导通，并进行吸烟口数计数，相对的，当判断结果为否时，则确定雾化电路 102 未导通，不进行吸烟口数计数。
（ 2 ）电流检测方案：请参考图 8C ， 雾化器组件 10 还包括：与雾化电路 102 和主电路 103 连接的电流检测电路 105 ，用于在 主电路 103 与电池组件 20 电连通后，检测雾化电路 102 的电流信号，并基于所述电流信号向主电路 103 反馈雾化电路 102 的实际导通情况。
具体的，请参考图 8D ，即在图 5 的基础进行改进，改进部分如图 8 中虚线框圈出部分所示，在开关管 Q1 的栅极与地的连线上串联电阻 R4 ，并在电阻 R4 和开关管 Q1 的栅极之间的连线上引出一条信号线，与单片机 PIC12F519 的一空闲管脚（如管脚 4-RB3 ）连接。此电流检测电路的设计原理为：当开关管 Q1 导通且发热电阻丝 R1 与电池组件 20 连通时，开关管 Q1 的栅源极会产生压差，使得单片机 PIC12F519 的管脚 4-RB3 获得一高电平信号，并基于此高电平信号确定雾化电路 102 实际导通，并进行吸烟口数计数；当开关管 Q1 导通且电阻 R1 与电池组件 20 未连通时，即电阻丝 R1 故障断开时，使得单片机 PIC12F519 的管脚 4-RB3 会获得一低电平信号，并基于此低电平信号确定雾化电路 102 实际未导通，不进行吸烟口数计数。
总而言之，在本申请实施例中，通过将电子烟的内置电路进行合理规划，主要分为电池组件和雾化器组件两个部分；将用于统计吸烟口数的主电路设置在雾化器组件内部，使得当雾化器组件与电源断开时，基于吸烟口数控制雾化器通断的控制单元无法对存储在雾化器组件中的吸烟口数进行操作；进一步，所述主电路根据雾化电路的实际导通次数统计吸烟口数，使得当所述主电路与电池组件连通，而雾化电路断路（如发热电阻丝故障）时，所述控制单元同样无法对存储在雾化器组件中的吸烟口数进行操作；必须在确定雾化电路实际导通且加热电阻丝实际工作后才对吸烟口数进行统计，以供控制单元控制使用； 实现了在进行吸烟口数限制时准确统计吸烟口数， 通过温度检测和电流检测来确定雾化电路是否实际导通，进一步提高了使统计的吸烟口数的准确性， 有效保证产品一致性（即有效吸烟口数和烟液量匹配）的技术效果。
另外，通过在雾化器组件内部设置接口电路，用于实现电池组件和雾化器组件的可拆卸组装连接，连接点集中，电池组件和雾化器组件通过接口电路通信，通信信号条理更清晰、控制逻辑更简化。主电路设计多样化，可仅基于存储器 IC 进行设计，也可基于控制芯片（如单片机）和存储器 IC 进行设计，满足多种应用需求；并且雾化器组件采用的芯片价格低廉，在统计的吸烟口数表明电子烟无法再继续使用时，无需重新写入程序，可直接将雾化器组件整体更换，操作简易、方便快捷，有效地提高了用户的使用体验。
实施例二
