具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现结合附图详细说明本发明的具体实施方式。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明的保护范围。
第一实施例：
请参看图1，本发明的第一实施例中提供了一种电子烟100，其包括发热件20、控制器30、传感器组件40、电池组件50以及带有与外界连通的吸气口11的烟嘴10。传感器组件40包括感应腔41以及设置在感应腔41内的传感器42。发热件20以及电池组件50均与控制器30电连接，传感器42与控制器30信号连接。发热件20设置 在感应腔41外。感应腔41的一端为开口端，感应腔41的另一端为封闭端，感应腔41的开口端与吸气口11连通。
当用户通过吸气口11进行抽吸时，感应腔41内的空气至少部分被吸出，感应腔41内气压减小，传感器42感应这一气压变化，产生触发信号并发送给控制器30，控制器30接收触发信号并控制电池组件50向发热件20提供电能。
当用户停止抽吸并将嘴从吸气口11上移开时，感应腔41通过吸气口11与外界连通，使得感应腔41内的气压回复，传感器42感应到气压回复，产生关机信号并发送给控制器30，控制器30接收关机信号并控制电池组件50停止向发热件20提供电能。
传感器组件40还包括分隔板43以及封堵件44。分隔板43设置在烟嘴11内，封堵件44位于烟嘴10相对吸气口11的一端，且封堵件44连接于分隔板43以及烟嘴11一侧的内壁之间，由此，烟嘴11一侧的内壁、分隔板43以及封堵件44围设成感应腔41。烟嘴10另一侧的内壁与分隔板43在相对吸气口11的一端围设成连接口12，连接口12与吸气口11连通。
在本具体实施方式中，封堵件44是一封堵管。封堵管的一端为开口端，另一端为封闭端。封堵管的开口端连接于分隔板43以及烟嘴11一侧的内壁之间且位于烟嘴10相对吸气口11的一端，封堵管的封闭端即为感应腔41的封闭端。可以理解地，封堵管的内腔也为感应腔41的一部分，传感器42可以设置在封堵管的内腔中。可以通过设置合适尺寸和/或形状的封堵管，灵活设置传感器42的位置。在本具体实施方式中，封堵管的封闭端靠近控制器30设置，传感器42设置在封堵管的内腔中且位于封堵管的封闭端，传感器42设置在该位置，便于传感器42与控制器30之间的电连接。
请参看图2，在另一个实施方式中，封堵件44是一封堵板。封 堵板连接于分隔板43以及烟嘴10一侧的内壁之间且位于烟嘴10相对吸气口11的一端。封堵板为感应腔41的封闭端。采用封堵板可以减小感应腔41的尺寸，由此，可以节约电子烟100内的空间，所节约的空间可以用烟液存储。另一方面，采用封堵板，使得传感器42靠近吸气口11，方便传感器42检测用户的抽吸动作。
可以理解地，在其他实施方式中，分隔板43以及封堵件44中的至少一个可以与烟嘴10一体成型。
请再次参看图1，进一步地，分隔板43靠近吸气口11的一端延伸至吸气口11内，将吸气口11分隔成相互隔离的第一吸气口111以及第二吸气口112，第一吸气口111与连接口12连通，第二吸气口112与感应腔41连通。电子烟100内形成的烟雾经连接口12、第一吸气口111流出，感应腔41内的空气由第二吸气口112被吸出，与连接口12、感应腔41共用同一吸气口11相比，可以有效防止烟雾从连接口12、感应腔41以及吸气口11三者的连通处进入感应腔41内，影响感应腔41内的气压，从而干扰传感器42的检测。
进一步地，传感器组件40还包括设置在感应腔41内且位于传感器41上方的薄膜45。薄膜45的设置可防外界污染物从吸气口11或第一吸气口111进入感应腔41内污染传感器42，从而影响传感器42的灵敏度。当用户通过吸气口11抽吸时，感应腔41内位于薄膜45上方的空气至少部分从吸气口11或第一吸气口111被吸出，薄膜45向上凸起，感应腔41内位于薄膜45下方的的空间增大，从而使得感应腔41内位于薄膜45下方的的空间的压力减小，传感器42感应这一气压变化，产生触发信号并发送给控制器30，控制器30接收关机信号并控制电池组件50停止向发热件20提供电能。当用户停止抽吸并将嘴从吸气口11上移开时，感应腔41内位于薄膜45上方的空间通过吸气口11或第一吸气口111与外界连通，气压回复，薄膜45的 形变回复，由此，感应腔41内位于薄膜45下方的的空间的气压也回复，传感器42感应到气压回复，产生关机信号并发送给控制器30，控制器30接收关机信号并控制电池组件50停止向发热件20提供电能。
电池组件50包括电池模块51以及充电模块52。控制器30以及充电模块52均与电池模块51电连接。电池模块51用于在控制器30的控制下向发热件20提供电能。充电模块52用于连接外部电源，使得外部电源为电池模块51充电。
电子烟100还包括与感应腔41隔离设置的气流通道60、用于存储烟液的储液件70以及壳体80。烟嘴10相对吸气口11的一端与壳体80连接，发热件20、控制器30、电池组件50、气流通道60以及储液件70均收容于壳体80内，传感器组件40收容于烟嘴10内，或传感器组件40部分收容于烟嘴10内，部分收容于壳体80内。壳体80上开设有进气孔81，气流通道60连通于连接口12和进气孔81之间，发热件20设置在气流通道60中并与储液件70连通。存储在储液件70内的烟液通过发热件20与储液件70之间的连通处流至发热件20，当电池模块51向发热件20提供电能时，发热件20在电驱动下加热烟液使其形成烟雾。外部空气通过进气孔81进入气流通道60，流经发热件20并与烟雾混合后，流向连接口12，最后从吸气口11或第二吸气口112流出，以供用户使用。
在本具体实施方式中，气流通道60大致呈L型，包括沿电子烟100径向设置的进气部61以及沿电子烟100轴向设置的出烟部62。发热件20为两端贯穿的中空结构，连通于进气部61与出烟部62之间，进气部61与出烟部62相对的一端与进气孔81连通，出烟部62与进气部61相对的一端与连接口12连通。
请参看图3，在另一个实施方式中，气流通道60包括沿电子烟 100轴向设置的进气部61以及沿电子烟100轴向设置且套设在进气部61内的出烟部62。进气部61的上端与进气孔81连通，进气部62的下端与发热件20连接。出烟部62的上端与连接口12连通，出烟部62的下端与发热件20之间留有间隙，所述间隙用于连通进气部61以及出烟部62。
本实施例中的电子烟100，感应腔41的一端为开口端，另一端为封闭端，且感应腔41的开口端与吸气口11连通，传感器42设置在感应腔41内，发热件20设置在感应腔41外，使得用户的抽吸动作可以直接作用于传感器42，无发热件20的阻碍。另一方面，感应腔41与气流通道60相互隔离，因此，不会因为渗漏的烟液堵住进气孔81而影响检测。此外，可以避免传感器42受气流通道60内潮湿环境的影响而缩短使用寿命，也可以避免渗漏的烟液导致传感器42的电路短路。
第二实施例：
请参看图4，本发明的第二实施例提供了一种电子烟200，其包括烟嘴10a、发热件20a、控制器30a、传感器42a、电池组件50a、气流通道60a、用于存储烟液的储液件70a以及壳体80a。烟嘴10a的一端开设有吸气口11a，烟嘴10a的另一端与壳体80a连接。发热件20a、控制器30a、传感器42a、电池组件50a、气流通道60a以及储液件70a均收容于壳体80a内。发热件20a、传感器42a以及电池组件50a均与控制器30a电连接。壳体80a上开设有进气孔81a，气流通道60a连通于吸气口11a和进气孔81a之间。发热件20a设置在气流通道60a中并与储液件70a连通。气流通道60a的通道壁至少部分由柔性材料制成以形成感应部，传感器42a设置在感应部上且位于气流通道60a的外侧。
当用户通过吸气口11a进行抽吸时，气流通道60a内的气压减小， 感应部发生形变，传感器42a感应这一形变，产生触发信号并发送给控制器30a，控制器30a接收触发信号并控制电池组件50a向发热件20提供电能。存储在储液件70a内的烟液通过发热件20a与储液件70a之间的连通处流至发热件20a，发热件20a在电驱动下加热烟液使其形成烟雾。外部空气从进气孔81a流入气流通道60a，与形成的烟雾混合后，从吸气口11a流出，以供用户使用。
当用户停止抽吸并将嘴从吸气口11a上移开时，气流通道60a通过吸气口11a与外界连通，使得气流通道60a内的气压回复，感应部的形变回复，传感器42a感应到形变回复，产生关机信号并发送给控制器30a，控制器30a接收关机信号并控制电池组件50a停止向发热件20a提供电能。
其中，传感器42a是电阻应变式传感器或电容式传感器。
在本具体实施例中，气流通道60a大致呈L型，包括沿电子烟200径向设置的进气部61a以及沿电子烟200轴向设置的出烟部62a。发热件20a为两端贯穿的中空结构，连通于进气部61a与出烟部62a之间，进气部61a与出烟部62a相对的一端与进气孔81a连通，出烟部62a与进气部61a相对的一端与吸气口11a连通。出烟部62a为一由柔性材料制成的两端贯穿的中空管，传感器42a设置在中空管的管壁外侧。
电池组件50a包括电池模块51a以及充电模块52a。控制器30a以及充电模块52a均与电池模块51a电连接。电池模块51a用于在控制器30a的控制下向发热件20a提供电能。充电模块52a用于连接外部电源，使得外部电源为电池模块51a充电。
本实施例中的电子烟200，传感器42a设置在气流通道60a的外侧并通过感应气流通道60a上的感应部的形变来获取用户的抽吸状况。传感器42a不设置在气流通道60a内，可以以避免传感器42a受 气流通道60a内潮湿环境的影响而缩短使用寿命，也可以避免渗漏的烟液导致传感器42a的电路短路。
