进一步地参见图3至图5所示，操作元件20被构造成是大致垂直于外壳10的纵向方向的；操作元件20具有较薄的形状，操作元件20的长度大于宽度并且长度大于厚度。操作元件20具有沿厚度方向相背的上侧表面和下侧表面；以及在装配后，操作元件20的下侧表面是被裸露于外壳10外的，进而用于供用户进行移动操作的；在一些示例中，操作元件20的下侧表面是不平整的，或者是凹凸不平的；进而对形成摩擦力以促进用户按压操作元件20进行移动操作是便利的。以及，卡勾21由操作元件20的上侧表面背离操作元件20延伸。

根据图6至图9所示，电子雾化装置100还包括：
用于存储液体基质的储液腔12，以及用于从储液腔12中吸取液体基质并加热雾化液体基质的雾化组件。为便于汽化和输出，储液腔12和雾化组件均是靠近近端110设置的。电子雾化装置100还包括沿纵向方向设置的气溶胶输出管11，该气溶胶输出管11至少部分于储液腔12内延伸，并由气溶胶输出管11的外壁与第一壳体10内壁之间的空间形成上述储液腔12。该气溶胶输出管11相对近端110的端部与吸气口113连通，以将雾化组件雾化生成的气溶胶输出至吸气口113处抽吸。
根据图6所示的实施例中，上述雾化组件包括：

加热元件14，位于气溶胶输出管11内，并且围绕导液元件13；加热元件14用于加热导液元件13内的至少部分液体基质生成气溶胶并释放至气溶胶输出管11。在该优选的实施中，加热元件14是围绕导液元件13的螺旋发热丝。
或者在又一些变化的实施中，导液元件13还可以被构造成是各种规则或非规则的形状，并部分与储液腔12流体连通以接收液体基质。或者在其他的变化实施中，导液元件13可以是更多的规则或者不规则的形状，例如多边形块状、表面具有凹槽的槽形形状、或者内部具有中空通道的拱形形状等。
或者在又一些变化的实施中，加热元件14可以是通过印刷、沉积、烧结或物理装配等方式结合在导液元件13上的。在一些其他的变化实施方式中，导液元件13可以具有用于支撑加热元件14的平面或曲面，加热元件14通过贴装、印刷、沉积等方式形成于导液元件13的平面或曲面上。或者在又一些 变化的实施中，加热元件14是形成于导液元件13表面的导电轨迹。在实施中，加热元件14的导电轨迹可以是通过印刷形成的印制线路的形式。在一些实施中，加热元件14是图案化的导电轨迹。在又一些实施中，加热元件14是平面的。在实施中，加热元件14是迂回、蜿蜒、往复或弯折延伸的导电轨迹。
进一步参见图6所示，外壳10内还设置有柔性的密封元件15；密封元件15至少部分支撑气溶胶输出管11，并密封储液腔12。则在装配后，由气溶胶输出管11的外壁与外壳10内壁之间界定的储液腔12，在靠近近端110的端部是封闭的；以及，储液腔12在朝向远端120的敞口是被密封元件15密封的。
密封元件15的形状基本是与储液腔12的朝向远端120的敞口适配的。以及，密封元件15上还设有朝向储液腔12延伸的凸缘152；在装配中，气溶胶输出管11背离吸气口113的端部插接在该凸缘152上，进而使气溶胶输出管11与密封元件15装配。以及，密封元件15的凸缘152是沿电子雾化装置100的纵向延伸的。
上述密封元件15还界定有沿电子雾化装置100的纵向方向贯穿该密封元件15的空气通道151，以在抽吸中供外界空气穿过密封元件15进入至气溶胶输出管11。根据图6中所示，空气通道151至少部分是由凸缘152围绕的，或者空气通道151是穿过凸缘152的。
进一步参见图6所示，电子雾化装置100还包括：
电芯16，至少部分被容纳和保持于外壳10内，并用于对加热元件14供电，电芯16位于密封元件15与远端120之间。具体地，加热元件14两端通过焊接引线，并由引线贯穿密封元件15后，再与电芯140建立导电连接。在一些具体的实施中，电子雾化装置100内还包括：电路板(图中未示出)，在电路板上集成有相关功能电路；以及，电路板是与电芯16抵靠或并列布置的；电路板例如PCB板沿电子雾化装置100的纵向延伸，并与电芯16基本平行并抵靠或贴合。以及，电路板与电芯16是导电连接的，加热元件14两端通过焊接引线，并由引线贯穿密封元件15后连接至电路板上，进而由电路板在电芯16和加热元件14之间引导电流。
进一步参见图6所示，电子雾化装置在抽吸期间的气流路径参见箭头R2 所示；电子雾化装置100的远端120设置有进气口121，以用于在抽吸中供外界空气进入至外壳10内。电芯16与外壳10之间具有空隙，进而使进气口121进入的空气能通过电芯16与外壳10之间的空隙进入密封元件15的空气通道151，而后穿过气溶胶输出管11并携带加热元件14加热生成的气溶胶输出至吸气口113。
参见图6至图9所示，电子雾化装置100包括：感测组件，以用于感测在抽吸中流过电子雾化装置100的气流变化；电路板上的控制器件根据该感测组件的感测结果，控制电芯16向加热元件14提供功率，以加热导液元件13内的液体基质生成气溶胶。上述感测组件包括：气流传感器40，例如咪头或压差传感器等，具有沿电子雾化装置100的纵向方向相背离的第一侧410和第二侧420。在装配后，沿电子雾化装置100的纵向方向，气流传感器40与电芯16是间隔布置的，并且气流传感器40的第一侧410是朝向或毗邻电芯16的，第二侧420是背离电芯16并朝向远端120的。气流传感器40通过第一侧410与电芯16保持有间隙，并且该间隙是与抽吸中流经电芯16周围的气流是连通的，或者该间隙提供了部分气流路径，进而使得气流传感器40能够感测抽吸中流过电子雾化装置100的气流变化。
在该实施例中，气流传感器40的第二侧420是与外界大气连通的，以用于感测外界大气的压力；进而气流传感器40能根据第一侧410和第二侧420的压力差值大于预设阈值时，确定用户的抽吸动作并输出高电平信号；进一步电路板上的控制器件根据气流传感器150输出的高电平信号控制电芯16向加热元件14输出电力以雾化液体生成气溶胶。
参见图6至图9所示，作为可选择的示例，上述感测组件还包括：柔性的密封元件50，例如由硅胶或热塑性弹性体等材质制备。密封元件50围绕或包裹气流传感器40，进而使气流传感器40的第一侧410和第二侧420是气流隔离的状态，从而使感测中第二侧420的压力不受第一侧410的压力的影响。
具体地，柔性的密封元件50围绕气流传感器40布置，并具有相背离的上端和下端；其中，密封元件50位于气流传感器40的第一侧410，并且密封元件50的上端的敞开的，即气流传感器40的第一侧410是显露或基本裸露的。密封元件50的下端位于气流传感器40的第二侧420，密封元件50的下端基本是包裹气流传感器40的第二侧420的；并且密封元件50的下端设置 有通孔51，通孔51用于供第二侧420与外界大气连通。
参见图3、图6、图10至图12所示，电子雾化装置100还包括：连通口124，位于或靠近远端120，并且是位于气流传感器40的第二侧420与远端120之间；以及，连通口124在远端120的端口位于滑槽122内。气流传感器40的第二侧420能通过该连通口124与外界大气连通，进而感测外界大气的压力。
具体地在图3、图6、图9至图12所示中，连通口124是与进气口121是彼此隔离的。密封元件50的下端还设置有至少部分环绕通孔51的凸沿52；在装配中，围绕或界定连通口124的壁是插入至凸沿52和/或通孔51内，进而直接与气流传感器40的第二侧420连通。以及，通孔51和/或凸沿52是偏离气流传感器40的第二侧420的中心布置的。
参见图2、图5和图11所示，操作元件20由用户按压操作下于在滑槽122内移动，并具有第一位置。具体地：
图2、图5和图11示出了操作元件20在第一位置中的示意图，在该第一位置下，操作元件20和阻尼元件30是关闭或遮挡连通口124的。则在该第一位置下，气流传感器40的第二侧420是密闭或与外界空气隔离的，则气流传感器40例如咪头或压差传感器是无法触发的，进而无法感测抽吸时流过电子雾化装置100的气流变化。则在该第一位置中，加热元件14无法响应用户的抽吸以加热液体基质产生气溶胶。并且在该实施中，滑槽122和/或操作元件20是与进气口121隔离的，进而在该第一位置中，进气口121是敞开的；当用户在吸气口113上进行抽吸时，能在进气口121和吸气口113之间形成穿过电子雾化装置100的气流，气流方向如图中箭头R2所示，但无气溶胶产生和输出。
图10和图12示出了操作元件20移动至第二位置中的示意图，在该第二位置中，操作元件20和阻尼元件30打开或显露连通口124；此时气流传感器40的第二侧420是通过该连通口124与外界空气连通的。则在该第二位置中，用户抽吸吸气口113时，外界空气能由进气口121进入并形成穿过电子雾化装置100的抽吸气流；而气流传感器40能基于第一侧410和第二侧420的压力差进而触发，使电路板控制电芯16向加热元件14供电加热生成气溶胶。
具体地例如图13示出了一个实施例中的气流传感器40的感测抽吸气流 的示意图；气流传感器40包括：
可变形的电极膜41，靠近第一侧410布置；
电极板42，靠近第二侧420布置；并且，可变形的电极膜41和电极板42是沿气流传感器40的轴向相对间隔布置的。气流传感器40基于可变形的电极膜41和电极板42之间的电容值，进而确定第一侧410和第二侧420的压力差。
例如图14示出了在抽吸时气流传感器40的状态；当抽吸气流流经第一侧410时由于第一侧410呈负压，而若可变形的电极膜41朝向电极板42的一侧的气压与外界大气连通，则可变形的电极膜41能朝向第一侧410弯曲或变形至图14所示的状态；当然，用户抽吸的力度越大第一侧410的负压越大，则可变形的电极膜41的形变也相应越大。则可变形的电极膜41与电极板42之间界定的电容值变化也是越大的；进而，气流传感器40基于以上电容值的变化确定第一侧410和第二侧420的压力差。而当第二侧420被操作元件20给封堵时，由于可变形的电极膜41朝向电极板42的一侧的气压与外界大气隔离，当用户抽吸时可变形的电极膜41无法响应抽吸的负压变形至相应的程度，进而无法使可变形的电极膜41和电极板42之间的电容变化达到响应的程度，进而气流传感器40无法响应用户的抽吸而触发。
以上通过操作元件20沿电子雾化装置100的宽度方向于滑槽122内在第一位置和第二位置之间移动；进而选择性地打开或关闭连通口124。具体地，当操作元件20移动至第一位置时能够关闭连通口124，使得电子雾化装置100处于锁定状态，此时阻止气流传感器40感测第一侧410和第二侧420的压力差；当操作元件20移动至第二位置时能够打开或导通连通口124，使得电子雾化装置100处于解锁状态，此时电子雾化装置能响应用户的抽吸生成气溶胶并输出至吸气口113供用户抽吸。因此以上电子雾化装置100能通过锁定状态阻止用户特别例如是未成年人的抽吸操作。
在一些实施中，电子雾化装置100可通过传感器件例如距离传感器、光传感器等检测操作元件20所处的位置，以确定操作元件20的位置状态；并在第一位置时阻止生成气溶胶。
在以上实施中，操作元件20在第一位置和第二位置均是避开进气口121的；进而在实施中，操作元件20在第一位置和第二位置时，进气口121始终 是打开或敞开的。或者，操作元件20在第一位置和第二位置时，用户抽吸时均能形成由进气口121流向吸气口113之间的气流通道。
或者在又一些变化的实施中，操作元件20是可以转动例如旋转等方式结合于外壳10上的；进而能通过旋转进而选择性地关闭或打开连通口124。
或者在又一些变化的实施中，操作元件20是可移除地结合于外壳10上的，例如操作元件20包括可拆卸的盖，当操作元件20结合于外壳10上时能关闭连通口124；以及当操作元件20从外壳10上拆卸时，则可打开连通口124。
在以上实施中，电子雾化装置100仅包括一个进气口121。
如图15和图16，其示出了又一个变化实施例的电子雾化装置100的示意图；在该实施中，操作元件20a的至少一部分能移动地在电子雾化装置100内布置，进而能选择性地关闭或打开气流传感器40a的第一侧410a。进而，当操作元件20a关闭气流传感器40a的第一侧410a时，在气流传感器40a的第一侧410a与电子雾化装置100的气流通道之间建立阻隔，从而阻止气流传感器40a感测用户抽吸时流经电子雾化装置100的气流，例如图15所示；而当操作元件20a打开气流传感器40a的第一侧410a时，以允许气流传感器40a感测用户抽吸时流经电子雾化装置100的气流，例如图16所示。作为可选的示例，操作元件20a的局部显露于电子雾化装置100的外表，或者操作元件20a连接其它显露于电子雾化装置100的外表的机构，从而提供用户操控。
进一步地图17示出了又一个变化实施例的电子雾化装置100中操作组件与外壳10b的分解示意图；在该实施中，外壳10b的远端120b设置有：
进气口121b，以用于在抽吸中供外部空气进入；
操作组件，设置于外壳10b的远端120b处，并被布置成可沿外壳10b的宽度方向移动。具体地根据图17和图18所示，操作组件包括操作元件20b和位于操作元件20b与外壳10b之间柔性的阻尼元件30b。
上述操作元件20b设置于外壳10b的远端120b处，并被布置成可沿外壳10b的宽度方向移动。具体地，外壳10b的远端120b设置有沿宽度方向延伸的滑槽122b；操作元件20b的至少部分于滑槽122b内线性地移动。
滑槽122b内设置有连通口124b；气流传感器40b的第二侧420b能通过该连通口124b与外界大气连通，进而感测外界大气的压力。
进一步地参见图17和图18所示，操作元件20b主要是薄片形状；操作元件20b上设置有垂直于该操作元件20b延伸出的卡勾21b，卡勾21b是纵长延伸的，以及卡勾21b的自由末端211b至少部分的横截面积增大，形成勾部。
柔性的阻尼元件30b至少部分被容纳或保持于操作元件20b的上侧表面的凹陷结构内；并且当操作元件20b于滑槽122b内移动时，柔性的阻尼元件30b用于在操作元件20b和外壳10b之间提供阻尼。
参见图17和图18所示，外壳10b的滑槽122b内还设置有卡勾孔123b，在装配中卡勾21b穿管该卡勾孔123b后与外壳10b连接。卡勾21b的外表面上布置有：至少一个沿纵向延伸的凸起26b；卡勾孔123b的内表面上布置有沿纵向布置的凹陷126b和凹陷125b。在使用中，当操作元件20b处于第一位置时，卡勾21b的凸起26b能伸入至凹陷126b内耦合或卡合，以使操作元件20b稳定地保持于第一位置，而不能沿宽度方向朝第二位置移动；以及，当操作元件20b处于第二位置时，卡勾21b的凸起26b能伸入至凹陷125b内，以使操作元件20b稳定地保持于第二位置，而不能沿宽度方向朝第一位置移动。
具体地参见图19所示，当操作元件20b处于第一位置时，由卡勾21b的凸起26b能伸入至凹陷126b内提供保持；并且连通口124b是被操作元件20b堵塞或遮挡或关闭的；并且在此状态下进气口121b是打开的；在此状态下凹陷125b是避开卡勾21b的。此时，气流传感器40b的第二侧420b无法感测外界大气的压力，进而气流传感器40b不能响应抽吸中气流流动。
以及在图19所示中，卡勾21b贯穿卡勾孔123b后，伸入至卡槽127b内。当用户需要将操作元件20b移动至第二位置时，则需要先按照图20所示进行操作，例如通过用手指抠拉操作元件20b或拔出操作元件20b，使操作元件20b背离外壳10b移动一定的行程，如图20中箭头R31所示；通过箭头R31所示的移动操作，使卡勾21b的凸起26b与凹陷126b分离或脱离解除在第一位置的保持，进而使操作元件20b能沿宽度方向线性移动。
进一步地在卡勾21b的凸起26b与凹陷126b分离以解除在第一位置的保持后，沿图21中箭头R32所示，将操作元件20b沿宽度方向朝向第二位置移动，移动至使凸起26b与凹陷125b对准。而与凸起26b与凹陷126b错开。移动至图21所示的状态中，凸起26b在纵向方向上与凹陷125b是脱离的，此时操作元件20b并未被紧固或稳定保持。
参见图22所示，将图21中的操作元件20b向外壳10b沿纵向向内推压或按压，使凸起26b伸入至凹陷125b内形成耦合或卡合，进而将操作元件20b在第二位置进行稳定保持，使操作元件20b不能沿宽度方向移动。当操作元件20b位于如图22所示的第二位置时，操作元件20b是避开进气口121b和连通口124b的，进而用户在抽吸时外部空气能由进气口121b进入电子雾化装置内形成抽吸气流；在此状态下气流传感器40b的第二侧420b能通过连通口124b感测外界大气的压力。
在以上实施中，操作元件20b上还布置有避让缺口24b和避让缺口23b；当操作元件20b在第二位置中时，避让缺口24b与连通口124b对准，进而避免遮盖或关闭连通口124b；以及当操作元件20b在第二位置中时，使得避让缺口23b与进气口121b对准，进而避免遮盖或关闭进气口121b。
当需要将操作元件20b由图22所示的第二位置移动至图19所示的第一位置时，则通过先由用户将操作元件20b向外抠出或拔出，以使凸起26b与凹陷125b脱离；而后即可朝向第一位置移动至图20所示的状态，最终将操作元件20b向内按压至使凸起26b伸入凹陷126b内结合。
进一步地在图17至图22所示的实施中，电子雾化装置100还包括：偏压元件25b，用于在第一位置中使操作元件20b的凸起26b朝伸入至凹陷126b内进行偏压或复位；以及在第二位置中使操作元件20b的凸起26b朝伸入至凹陷125b内进行偏压或复位。提供偏压元件25b对于替换用户在操作中对操作元件20b进行按压是更加便利的。
例如在图17至图22所示的实施中，偏压元件25b是围绕或缠绕在卡勾21b在上的弹簧25b；在布置中，弹簧25b的一端抵靠于自由末端211b、另一端抵靠于卡槽127b的内壁上；当用户在第一位置和/或第二位置将操作元件20b从外壳10b上向外抠出或拔出时，弹簧25b会被压缩。而后当用户移动操作完成之后，弹簧25b通过弹性恢复力进而使操作元件20b朝外壳10b偏压。
如图23和图29所示，其示出了又一个变化实施例的电子雾化装置100的示意图；在该实施例中，电子雾化装置100包括：
外壳10c，基本界定电子雾化装置100的外表面，具有沿纵向方向相对的近端110c和远端120c。
吸气口113c，以用于供用户进行抽吸；位于外壳10c的近端110c。
操作元件20c，设置于外壳10c的远端120c处，并被布置成可沿外壳10c的宽度方向移动。具体地，外壳10c的远端120c设置有沿宽度方向延伸的滑槽122c；操作元件20c被至少部分容纳和保持于滑槽122c内移动。同时，滑槽122c的侧边上设置有沿外壳10c的宽度方向延伸的限位凹部122c1；操作元件20c上设置有伸入至限位凹部122c1内的卡凸20c1；进而在移动中，通过限位凹部122c1对操作元件20c的移动进行限位。同时，通过限位凹部122c1和卡凸20c1的配合，阻止操作元件20c从滑槽122c内脱出。
进一步参见图23和图24所示。操作元件20c具有沿厚度方向相背的第一端壁20c2和第二端壁20c3、以及在第一端壁20c2和第二端壁20c3之间延伸的周侧壁20c4。卡凸20c1位于周侧壁20c4上。在装配后，操作元件20c的第一端壁20c2是朝向外壳10c的滑槽122c内并非显露的，第二端壁20c3是裸露于外壳10c的远端120c的。第二端壁20c3设置有若干凸棱20c5，用于在用户按压第二端壁20c3对操作元件20c进行移动操作时提供摩擦，对于用户操作是便利的。凸棱20c5是垂直于操作元件20c的长度方向的。
操作元件20c的第一端壁20c2上设置有容纳凹腔20c6，该容纳凹腔20c6用于容纳和安装阻尼元件30c。在装配后，阻尼元件30c沿电子雾化装置100的纵向方向位于操作元件20c和外壳10c之间，以在操作元件20c的移动中提供阻尼。
进一步参见图23和图24所示，阻尼元件30c同样也被构造成是薄的形状；在装配后，阻尼元件30c是被操作元件20c和外壳10c从厚度方向的两侧压缩的。阻尼元件30c朝向外壳10c的表面设置有凸起30c1，对于抵靠至外壳10c形成挤压或压缩提供阻尼是有利的。
在该实施例中，电子雾化装置100还包括：
支架60c，位于密封元件50c和远端120c之间；支架60c是刚性的，并具有支撑臂60c1，该支撑臂60c1插入至密封元件50c内以对密封元件50c提供支撑。电芯16c至少部分被容纳和保持于支架60c上；并用于对加热元件14c供电。具体地，密封元件50c上设置有引线孔50c1，装配后加热元件14c的两端通过穿过引线孔50c1的引线连接至电芯16c，进而使加热元件14c连通。
连通口124c，位于滑槽122c内的连通口124c与外界大气连通。
气流传感器40c，例如咪头或压差传感器等，具有沿电子雾化装置100的纵向方向相背离的第一侧40c1和第二侧40c2。第一侧40c1是朝向电芯16c布置的，第二侧40c2是朝向远端120c的，并能通过位于滑槽122c内的连通口124c与外界大气连通。
位于电芯16c与远端120c的之间的第一气流通道70c；该第一气流通道70c具有位于滑槽122c内的第一进气口71c。
进一步参见图23至29所示，操作元件20c上设置有第一通孔20c7，阻尼元件30c上设置有与第一通孔20c7相对并连通的第二通孔30c2。操作元件20c由用户按压第二端壁20c3在滑槽122c内移动，并具有第一位置和第二位置。具体地：
图25和图28示出了操作元件20c第一位置中的示意图，在该第一位置下，操作元件20c和阻尼元件30c是关闭第一气流通道70c的第一进气口71c的。同时，在该第一位置下，操作元件20c和阻尼元件30c是关闭连通口124c的；则在该第一位置下，气流传感器40c的第二侧40c2是密闭或与外界空气隔离的，则气流传感器40c是无法触发的。则在该第一位置中，电路板控制阻止电芯16c向加热元件14c提供电力，用户无法抽吸。并且在该实施中，外界空气无法通过第一进气口71c进入至外壳10c内，此时用户抽吸吸气口113时，由于无抽吸气流产生，具有较大的吸阻。
图26和图29示出了操作元件20c移动至第二位置中的示意图，在该第二位置中，操作元件20c和阻尼元件30c打开或显露第一气流通道70c的第一进气口71c；以及连通口124c与操作元件20c的第一通孔20c7、阻尼元件30c的第二通孔30c2均是对准进而与外界空气连通；此时气流传感器40c的第二侧40c2是与外界空气连通的。则在该第二位置中，用户抽吸吸气口113时，外界空气能沿图29中箭头R4所示通过第一气流通道70c进入至外壳10c内；而后再沿箭头R2所示，经电芯16c与外壳10c之间的缝隙流向气溶胶输出管；同时，气流传感器40c能根据第一侧40c1和第二侧40c2的压差大于预设阈值进而触发，使电路板控制电芯16c向加热元件14c供电加热生成气溶胶。
以上通过操作元件20c沿图25和图26中箭头P所示，在第一位置和第二位置之间移动，进而选择性地打开或关闭第一气流通道70c和连通口124c。 具体地，当移动至第一位置时，关闭第一气流通道70c和连通口124c形成电子雾化装置100的锁定状态，此时阻止加热元件14c加热生成气溶胶并使抽吸时具有较高的吸阻以阻止抽吸；当移动至第二位置时，打开或导通第一气流通道70c和连通口124c形成电子雾化装置100的解锁状态，此时用户能进行气溶胶抽吸。进而以上电子雾化装置100能通过锁定状态阻止用户特别例如是未成年人的抽吸。
如图30和图35所示，其示出了又一个更加优选的变化实施例的电子雾化装置100的示意图；在该实施中，电子雾化装置100包括：
外壳10d，具有沿纵向方向相背离的近端110d和远端120d；外壳10d内设置有靠近近端110d的气溶胶输出管11d和储液腔12d；
导液元件13d，由储液腔12d延伸至气溶胶输出管11d内，以吸取液体基质；加热元件14d位于气溶胶输出管11d内并围绕导液元件13d，以加热导液元件13d内的至少部分液体基质生成气溶胶；
密封元件50d，密封储液腔12d，并具有插接部50d1供气溶胶输出管11d插接；密封元件50d上设置有引线孔50d2，供引线穿过引线孔50d2后将加热元件14d连接至电芯16d；密封元件50d上空气通道151d，以供由远端120d进入的空气流入气溶胶输出管11d；
支架60d，是刚性的并具有支撑臂60d1，该支撑臂60d1插入至密封元件50d内以对密封元件50d提供支撑；
电芯16d，被容纳和保持于支架60d；用于向加热元件14d输出电力。
进一步参见图32至图35所示，该实施例的电子雾化装置100还包括：
气流传感器40d，第一侧40d1是朝向电芯16d布置的，并且第一侧40d1是与电芯16d与外壳10d之间的缝隙气流连通的，进而能通过感测用户抽吸过程中流过电芯16d与外壳10d之间缝隙的气流；第二侧40d2是朝向远端120d的，并能通过位于滑槽122d内的连通口124d与外界空气连通。
第一气流通道70d，该第一气流通道70d具有位于滑槽122d内的第一进气口71d；第一气流通道70d以用于供外界空气由第一进气口71d进入至外壳10d内，具体地是供外界空气由第一气流通道70d进入至电芯16d与外壳10d之间的缝隙，进而最终进入气溶胶输出管11d。
第二气流通道72d，该第二气流通道72d具有位于滑槽122d内的第二进 气口73d；第二气流通道72d以用于供外界空气由第二进气口73d进入至外壳10d内。
操作元件20d和阻尼元件30d，位于远端120d并能在外壳10d的滑槽122d内移动，选择性地在第一位置和第二位置之间进行配置。具体地：
图32和图34示出了第一位置的示意图，操作元件20d在第一位置中遮挡或关闭第一气流通道70d的第一进气口71d和连通口124d；以阻止气流传感器40d触发锁定电子雾化装置100。同时在第一位置中，当用户抽吸气口113d时，外界空气能由第二气流通道72d的第二进气口73d进入外壳10d内，如图32中箭头R3所示；而后再经电芯16d与外壳10d之间的间隙流向空气通道151d和气溶胶输出管11d。在该实施例的电子雾化装置100中，锁定状态下用户抽吸时不加热产生气溶胶，但仍然穿过电子雾化装置100的气流；锁定状态下仍然能抽吸空气而不呈现大的吸阻，对避免引起未成年人发现或发觉电子雾化装置100被锁定是有利的。
以及，第二进气口73d的面积是大于第一进气口71d的面积的。
进一步当操作元件20d和阻尼元件30d移动至第二位置时，如图33和图35所示，连通口124d通过操作元件20d的第一通孔840a、阻尼元件30d的第二通孔92a均是对准进而与外界空气连通；第一气流通道70d的第一进气口71d是打开或显露的，抽吸时外界空气能沿图中箭头R4所示进入外壳10d内。此时电子雾化装置100呈解锁状态，用户抽吸时气流传感器40d例如咪头或压差传感器能响应抽吸动作触发产生高电平信号，进而电路板根据气流传感器40d的触发控制电芯16d向加热元件14d输出电力。同时根据图33和图35所示的第二位置中，第二气流通道72d的第二进气口73d是被遮挡或关闭的；以阻止外界空气由第二气流通道72d进入外壳10d内。
该优选实施例的电子雾化装置100，在锁定状态时阻止产生气溶胶，并仍然具有穿过电子雾化装置100的气流，对于阻止未成年人发觉电子雾化装置100被锁定是有利的。
在又一些优选的实施中，在锁定状态下，当用户抽吸时由第二气流通道72d进入外壳10d内空气，是避开气流传感器40d的第一侧40d1的；或者在锁定状态下，抽吸时的气流是与气流传感器40d的第一侧40d1分离的；则进一步对于阻止气流传感器40d的触发是有利的。
进一步根据图32和图33中所示的优选实施，第一气流通道70d的横截面积小于第二气流通道72d的横截面积；对于在锁定状态被未成年人抽吸中，降低吸阻进一步避免被未成年人察觉被锁定是有利的。
进一步在图34所示的优选实施中，第二进气口73d是孔径大约为1～3mm；并且第二进气口73d的数量包括多个，例如图34中所示为呈环状布置的6个。
进一步在更加优选的实施中，第一气流通道70d和第二气流通道72d均是沿电子雾化装置100的纵向方向延伸；并且第一气流通道70d和第二气流通道72d沿电子雾化装置100的宽度方向间隔布置。以及，气流传感器40d沿电子雾化装置100的宽度方向位于第一气流通道70d和第二气流通道72d之间。
以及，气流传感器40d是靠近电子雾化装置100的宽度方向的中央的；以及，第一气流通道70d和/或第二气流通道72d是偏离电子雾化装置100的宽度方向的中央的。
或者在又一些变化的实施中，电子雾化装置100的外壳10d被构造成是不同于以上扁形的纵长的圆柱形形状；操作元件20d是至少部分围绕外壳的环形或弧形形状。则对应地在操作中，通过驱动操作元件20d围绕外壳的周向的转动，以调整操作元件20d的位置使其在第一位置和第二位置之间进行配置。
或者在又一些变化的实施中，第一气流通道70d和第一进气口71d相应地布置于远离远端120d的位置；例如在一些实施中，第一气流通道70d和第一进气口71d位于电芯16d与密封元件50d之间。或者例如在一些实施中，第一气流通道70d和第一进气口71d界定于支架60d与密封元件50d之间。则操作元件20d则对应调整布置于外壳10d上相对应的位置。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但并不限于本说明书所描述的实施例，进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
