进一步参见图3至图5所示，主壳体10的内部设置有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。其中，雾化组件通常包括用于吸取液体基质的毛细导液元件、以及结合于导液元件的加热元件，加热元件在通电期间加热导液元件的至少部分液体基质生成气溶胶。在可选的实施中，导液元件包括柔性的纤维，例如棉纤维、无纺布、玻纤绳等等，或者包括具有微孔构造的多孔材料，例如多孔陶瓷；加热元件可以是通过印刷、沉积、烧结或物理装配等方式结合在导液元件上，或缠绕在导液元件上的。
进一步在图3至图5所示的优选实施中，雾化组件包括：用于吸取和传递液体基质的多孔体30、以及对多孔体30吸取的液体基质进行加热汽化的加热元件40。具体：
在图5所示的剖面结构示意图中，主壳体10内设有沿轴向设置的烟气传输管11；主壳体10内还设有用于存储液体基质的储液腔12。在实施中，该烟气传输管11至少部分储液腔12内延伸，并由烟气传输管11的外壁与主壳体10内壁之间的空间形成储液腔12。该烟气传输管11相对近端110的第一端与吸嘴口A连通、相对远端120的第二端与多孔体30的雾化面310与端盖20之间界定形成的雾化腔室340气流连接，从而将加热元件40汽化液体基质生成并释放至雾化腔室340的气溶胶传输至吸嘴口A处吸食。
参见图3、图4和图5所示的多孔体30的结构，该多孔体30的形状被构造成在实施例中可大致呈但不限于块状结构；根据本实施例的优选设计，其包括呈拱形形状，具有沿主壳体10的轴向方向朝向端盖20的雾化面310；其中，在使用中多孔体30背离雾化面310的一侧与储液腔12流体连通进而可吸收液体基质，多孔体30内部所具有的微孔结构再将液体基质传导至雾化面310受热雾化形成气溶胶，并从雾化面310释放或逸出。

具体结构和形状上，柔性的密封元件50大体呈中空的筒状，内部中空用于容纳多孔体30，并通过紧配的方式套设在多孔体30外。
刚性的支架60则对套设有柔性的密封元件50的多孔体30进行保持，在一些实施例中可包括大致呈下端为敞口的环状形状，保持空间64用于容纳并保持柔性的密封元件50和多孔体30。柔性的密封元件50一方面可以在多孔体30与支架60之间对它们之间的缝隙进行密封，阻止液体基质从它们之间的缝隙渗出；另一方面，柔性的密封元件50位于多孔体30与支架60之间，对于多孔体30被稳定容纳在支架60内而避免松脱是有利的。
柔性的第一密封元件70设置于储液腔12与支架60之间，且其外形与主壳体10内轮廓的横截面适配，从而对储液腔12实现密封防止液体基质从储液腔12漏出。进一步为了防止柔性材质的第一密封元件70的收缩变形影响密封的紧密型，则通过以上支架60容纳在柔性的第一密封元件70内对其提供支撑。
在安装之后，为了保证液体基质的顺畅传递和气溶胶的输出，柔性的第一密封元件70上设置有供液体基质流通的第一导液孔71、支架60上对应设置有第二导液孔61，柔性的密封元件50上设置有导液孔51。在使用中储液腔12内的液体基质依次经第一导液孔71、第二导液孔61和导液孔51流向保持于柔性的密封元件50内的多孔体30上，如图4和图5中箭头R1所示，进而被吸收后传递至雾化面310上汽化，生成的气溶胶会释放至雾化面310与端盖20之间界定的雾化腔室340内。
在抽吸过程中气溶胶的输出路径上，参见图3至图6，柔性的第一密封元件70上设置有供烟气传输管11下端插接的第一插孔72，对应支架60上设置有第二插孔62，支架60上与主壳体10相对的一侧设置有将雾化面310与第二插孔62气流连通的气溶胶输出通道63。在安装之后，完整的抽吸气流路径参见图4中箭头R2所示，外部空气经由端盖20上的第一进气口23进入至雾化腔室340，而后携带生成的气溶胶由气溶胶输出通道63流向第二插孔62后，经第一插孔72向烟气传输管11输出。
参见图6所示的优选实施中，多孔体30的形状呈拱形形状，并具有沿厚度方向相对的第一侧部31和第二侧部32、以及在第一侧部31和第二侧部32之间延伸的基座部分34；该基座部分34的下表面被配置为雾化面310。并且第一侧部31和第二侧部32是沿多孔体30的长度方向延伸的，进而在第一侧部31、第二侧部32和基座部分34之间界定沿多 孔体30的长度方向延伸的液体通道33，并通过该液体通道33接收和吸收由第一导液孔71、第二导液孔61和导液孔51流下的液体基质。
进一步根据图6和图5所示，多孔体30还包括于第一侧部31、第二侧部32之间沿雾化器100的横截面方向延伸的支撑部分35。密封元件50大体呈中空的筒状，内部中空是用于容纳和包覆多孔体30的容纳腔，进而装配后包裹在多孔体30外。密封元件50内表面上设有若干用于在安装之后提升密封效果的凸筋52，这些凸筋52主要是密封支架60和多孔体30之间的缝隙，以防止液体传递的过程中由支架60和多孔体30之间的缝隙渗漏；因而在实施中，若干凸筋52共同使形成闭合的环形，并且是完整环绕或包围液体传递通道的，进而实现比较好的密封效果。
密封元件50的构造参见图7和图8所示，密封元件50呈下端为敞口的方筒的形状，密封元件50形成容纳和包围多孔体30的容纳腔的内壁包括：
沿长度方向相对的第一内侧壁510和第二内侧壁520；
沿宽度方向相对的第三内侧壁530和第四内侧壁540；
以及内顶壁550，毗邻或包覆多孔体30的支撑部分35，装配后是由多孔体30的支撑部分35提供支撑。
密封元件50的内壁上的凸筋52包括：
第一区段521，位于第一内侧壁510上，沿密封元件50的宽度方向延伸，并与多孔体30的基座部分34相对，在装配后与多孔体30的基座部分34抵靠形成过盈配合密封它们的缝隙；
第二区段522，位于第一内侧壁510上，沿密封元件50的纵向方向延伸；并与多孔体30的第一侧部31沿长度方向的一侧端面相对，在装配后与多孔体30的第一侧部31抵靠形成过盈配合；
第三区段523，位于内顶壁550上，沿密封元件50的长度方向延伸；并与多孔体30的第一侧部31相对，在装配后与多孔体30的第一侧部31抵靠形成过盈配合；
第四区段524，位于第二内侧壁520上，沿密封元件50的纵向方向延伸；并与多孔体30的第一侧部31沿长度方向的一侧端面相对，在装配后与多孔体30的第一侧部31抵靠形成过盈配合；
第五区段525，位于第二内侧壁520上，沿密封元件50的宽度方向延伸，并与多孔体30的基座部分34相对，在装配后与多孔体30的基座部分34抵靠形成过盈配合密封它们的缝隙；
第六区段526，位于第二内侧壁520上，沿密封元件50的纵向方向 延伸；并与多孔体30的第二侧部32沿长度方向的一侧端面相对，在装配后与多孔体30的第二侧部32抵靠形成过盈配合；
第七区段527，位于内顶壁550上，沿密封元件50的长度方向延伸；并与多孔体30的第二侧部32相对，在装配后与多孔体30的第二侧部32抵靠形成过盈配合；
第八区段528，位于第一内侧壁510上，沿密封元件50的纵向方向延伸；并与多孔体30的第二侧部32沿长度方向的一侧端面相对，在装配后与多孔体30的第二侧部32抵靠形成过盈配合。
进一步根据图7和图8所示，凸筋52的数量共有八段，进而通过顺次首位相连的方式连接形成闭合的形状。当然，以上由凸筋52形成的闭合环是具有沿雾化器100的长度方向具有跨度的非平面的闭合环。
在实施中，导液孔51是位于由凸筋52形成的闭合环内的。
进一步在图8和图9所示的优选实施中，密封元件50的内顶壁550具有沿长度方向的两侧设有定位悬臂53。在图8中定位悬臂53是沿纵向延伸出的。在与多孔体30装配中，两个定位悬臂53分别从两侧夹持或贴合多孔体30的支撑部分35，便于它们装配过程中的辅助引导定位。
图10和图11示出了又一个实施例的密封元件50a的结构示意图，其内壁上的凸筋52a按照图10中所示，包括有：
顺次首尾连接形成围绕一个导液孔51a的第一闭合环的第一区段521a、第二区段522a、第三区段523a、第四区段524a、第五区段525a、第六区段526a；以及顺次首尾连接形成围绕另一个导液孔52a的第二闭合环的的第七区段5210a、第八区段5220a、第九区段5230a、第十区段5240a、第十一区段5250a、第十二区段5260a。
以上第一闭合环靠近第一内侧壁510a、第二闭合环靠近第二内侧壁520a。
以上密封元件50a在与多孔体30装配后，第四区段524a和第十区段5240a均是抵靠或贴合多孔体30的支撑部分35，形成过盈配合。第四区段524a和第十区段5240a沿密封元件50a的长度方向分别布置于内顶壁550a的两侧。
图12示出了又一个实施例的密封元件50b的结构示意图，相比图8的密封元件50的构造；其凸筋52b具有在第三区段523b和第七区段527b之间沿宽度方向延伸的第九区段529b，并由该第九区段529b将第一区段521b至第八区段528b顺次连接形成的闭合环分隔成两个分别围绕导液孔51b环形部分。
根据以上，凸筋52/52a/52b在装配之后的各个区段均能被多孔体 30支撑，进而稳定地形成过盈密封它们之间、以及多孔体30与支架60之间的缝隙。
进一步参见图13所示，硅胶材质的密封元件50与有机聚合物塑胶材质的支架60是通过预制成型例如双色注塑一同在模具内注塑成型获得的；直接通过预制成型如双色注塑工艺将密封元件50成型结合于支架60的保持空间64的内壁。
进一步图14示出了又一个实施例的密封元件50c的结构示意图，该密封元件50c的内壁上形成有凸筋52c；同时，在外表面上还设置有第二凸筋54c，在装配之后第二凸筋54c与支架60的保持空间64的内表面抵靠，从而密封它们之间的间隙。
从图14所示的实施中可以看出，第二凸筋54c与内壁上的凸筋52c基本是相同的形状，于外表面上与凸筋52c相对的位置布置。
进一步在图15所示的实施例中提出了一种具有更优的密封效果防止液体基质在各部件的接合缝隙之间渗漏的多孔体30c和密封元件50c的结构；具体，
多孔体30c包括：
沿雾化器100的横截面方向延伸的基座部分310c，该基座部分310c的上下表面则可以分别被作为吸液面和雾化面310，吸液面与雾化面310相背设置，吸液面和雾化面310沿所述多孔体30c的第一方向设置。
第一延伸臂320c和第二延伸臂330c；由基座部分310c沿雾化器100的长度方向向上延伸形成，雾化器100的长度方向与多孔体30c的第二方向平行；在图15中所示的优选实施中，第一延伸臂320c和第二延伸臂330c分别沿着雾化器100的厚度方向设置于基座部分310c相对的两侧，雾化器100的厚度方向与多孔体30c的第三方向平行；
进一步在图15所示的优选实施中，多孔体30c还包括于第一延伸臂320c和第二延伸臂330c之间沿雾化器100的横截面方向延伸的支撑部分340c。
密封元件50c大体呈中空的筒状，包裹在多孔体30c外。
密封元件50c外表面上设有若干用于在安装之后提升密封效果的凸筋，这些凸筋主要是密封支架60和多孔体30c之间的液体基质传递通道，以防止液体传递的过程中由支架60和多孔体30c之间的缝隙渗漏；因而在实施中，若干凸筋共同使形成闭合的环形，并且是完整环绕或包围体传递通道的，进而实现比较好的密封效果；具体包括：
第一凸筋510c，数量为两段，分别设置于密封元件50c沿宽度方向的两个外侧壁上；并且在图中第一凸筋510c呈沿厚度方向延伸。
并且在装配后的位置上第一凸筋510c与多孔体30c的基座部分310c是对应或重合的，进而使得该第一凸筋510c能由基座部分310c提供支撑，使第一凸筋510c能紧密的抵靠在支架60的内壁上。
第二凸筋520c，数量为两段，分别设置于密封元件50c的顶壁表面靠近厚度方向的两侧上；在图中被构造呈沿宽度方向延伸，并且在位置上分别是支撑部分340c相对的，进而在安装后能由支撑部分340c提供支撑，使第二凸筋520c能紧密的抵靠在支架60的内壁上。
第三凸筋530c，数量包括有四段，具体是分别设置于密封元件50c沿厚度方向的两个外侧壁上(在图中对侧的两段第三凸筋530c被遮挡进而未显示)；并具有沿长度方向的第一端与第一凸筋510c连接、第二端与第二凸筋520c连接。在安装之后，第三凸筋530c由第一延伸臂320c和第二延伸臂330c的外侧壁提供支撑，使第三凸筋530c紧密地抵靠于支架60的内壁上。
根据图15的优选实施，第三凸筋530c的数量共有四段，进而通过相连的方式使设置于密封元件50c上的第一凸筋510c、第二凸筋520c和第三凸筋530c连接形成闭合的形状。当然，以上由凸筋形成的闭合的形状是具有沿雾化器100的长度方向具有跨度的非平面的闭合环。
同时根据图15的优选实施，第三凸筋530c是沿宽度方向向外倾斜设置的。
进一步在图15所示的优选实施中，密封元件50c上设置有位于相对的两个第二凸筋520c之间的通孔540c，在实施中该通孔540c是与刚性支架60上的第二插孔62相对的，进而可以使在烟气传输管11内传输的气溶胶的冷凝液向下坠落进而通过通孔540c被支撑部分340c承接和吸收。
图16提出了又一个可选的实施的密封元件50d上设置凸筋提升密封效果的示意图，在该实施例中具有两个相互分离、并且各自呈闭合的环形的凸筋；具体：
由设置于一宽度方向的侧壁上的第一凸筋510d、设置于顶部上的第二凸筋520d和位于厚度方向的两个侧壁上的两段第三凸筋530d组成第一闭合的环；
同样地，还包括有另一个第四凸筋511d、第五凸筋521d和两段第六凸筋531d组成第二闭合的环。
当然，以上若干凸筋形成的闭合的环是相互独立，以及沿宽度和厚度方向对称设置于密封元件50d上的。
在图16所示的优选实施例的凸筋结构布置上，两个对称的闭合的 环，分别各自围绕两个流体连通口51d，进而防止在液体基质传递的过程中从支架60与多孔体30c之间的缝隙渗出。
并且根据图16所示的优选实施中，密封元件50d沿厚度方向的两侧设置有通过凹陷形成的在抽吸过程中供气溶胶输出的通道部分540d，形成抽吸过程中气流路径R2的一部分。对应第三凸筋530d和第六凸筋531d是分别布置在该通道部分540d两侧的。
进一步根据图15和图16所示的优选实施，形成的闭合的环形凸筋的延伸路径是完整地经过密封元件50c/50d的全部外表面的，即密封元件50c/50d沿宽度方向的左右两外侧壁、厚度方向的前后两个外侧壁、以及顶壁外表面上均是有闭合的环的一部分在它们上延伸。
在图17所示的又一个可选的实施中，密封元件50e的两个闭合的环形的凸筋中，第二凸筋520e包括相互呈一定夹角的两个部分组成；对应第五凸筋521e类似同样具有呈一定夹角的两个部分。
当然在该图17所示的密封元件50e中，第二凸筋520e和第五凸筋521e同样均是由支撑部分340c提供支撑的。
并且在该图17所示的密封元件50e，实施例中图17中由若干凸筋顺次连呈的两个闭合的环形是可以相连的。
同时，在以上图15至图17所示的优选实施中，以上若干凸筋是沿着雾化器100的厚度方向或宽度方向呈对称设置的。
以上电子烟雾化器采用对应适配于具有支撑部分340c的多孔体30c的结构，在密封元件50c/50d/50e上设置能与多孔体30c的各部分对应的凸筋，从而使得在装配后能比较完全地使多孔体30c与刚性支架60之间紧密地抵靠并隔离导液通道，提升密封效果。
