进一步在图2所示的实施中，在端盖20上设置有用于与电源装置的导电连接的电极柱21，以及用于在抽吸的过程中供外部空气进入至雾化器100内的进气孔22。
进一步参见图3至图5所示，外壳体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中吸取液体基质的多孔体31、以及对多孔体31吸取的液体基质进行加热汽化的加热元件32。具体，在图4所示的剖面结构示意图中，外壳体10内设有沿轴向设置的烟气传输管11，该烟气传输管11的外壁与外壳体10内壁之间的空间形成用于存储液体基质的储液腔12；该烟气传输管11一端与吸烟口A连通、另一端与雾化腔室内气流连通，进而将生成的气溶胶输出至吸烟口A处供用户吸食。
参见图3和图10所示的多孔体31的结构，该多孔体31的形状被构造成具有大体呈拱形形状，包括板状部311、以及设置于板状部311上的支撑部312。其中板状部311的上表面被构造成吸液面，在使用中吸液面是与储液腔12流体连通的，进而可以接收从储液腔12流出的液体基质；板状部311的下表面被构造成雾化面，其上设置加热元件32；在使用中，多孔体31内部所具有的微孔结构将吸液面吸取的液体基质传导至雾化面上被加热元件32汽化形成气溶胶，并从雾化面释放逸出。
在图10所示的多孔体31结构上，由于吸液面与雾化面相互平行，液体基质和气溶胶在多孔体31中的移动方向均与雾化面所在的平面相垂直。液体基质在多孔体31内的移动将更加流畅，且制造比较方便。
在一些实施方式中，多孔体31可由多孔陶瓷、多孔玻璃陶瓷、多孔玻璃等硬质毛细结构制成。加热元件32优选采用通过具有导电性的原材料粉末与印刷助剂混合成浆料后于印刷后烧结的方式形成在雾化面上，从而使其全部或绝大部分表面都与雾化面紧密结合，具有雾化效率高、热量损失少、防干烧或大大的减少干烧等效果。该加热元件32在一些实施例中可采用不锈钢、镍铬合金、铁铬铝合金、金属钛等材质。
进一步参见图3、图4、图6、图8和图9，为了辅助对多孔体31的安装固定、以及对储液腔12进行密封，在外壳体10内还设有密封和保持机构；包括：
硅胶套40，套设在多孔体31外，并且由多孔体31的支撑部312提 供支撑，防止其变形等。
刚性的支撑套50，大体呈环状，内部中空用于容纳并保持套设有硅胶套40的多孔体31，并通过柔性紧配的方式将套设有硅胶套40的多孔体31保持在内部。
硅胶密封座60，设置于储液腔12朝远端120的端部，且其外形与外壳体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。并且，硅胶密封座60呈中空的形状，在设置中是套设在刚性的支撑套50外的。可以通过刚性的支撑套50的支撑，防止柔性材质的硅胶密封座60的收缩变形影响密封的紧密型。
进一步，硅胶密封座60上设置有第一导液孔62，刚性的支撑套50上设置有第二导液孔54，以及位于硅胶套40上的第三导液孔41；第一导液孔62、第二导液孔54和第三导液孔41顺次连通，形成用于供储液腔12内的液体基质流向吸液面的流通通道。
进一步，在硅胶密封座60上设置有第一插接孔61、刚性的支撑套50上设置有第二插接孔51，用于供外壳体10内的烟气传输管11插接。同时，刚性的支撑套50靠近厚度方向的一侧设置有气流通道52，与烟气传输管11是气流连通的，进而用于供雾化腔室内的气溶胶通过该气流通道52输出至烟气传输管11内。
进一步参见图4至图6所示，端盖20还设置有朝刚性的支撑套50延伸出的支撑臂24，在使用中用于对支撑套50提供支撑，使支撑套50稳定保持在外壳体10内。
进一步在端盖20与多孔体31的雾化面之间设置有隔板70，该隔板70一方面可以承接由雾化面渗出的液体基质；另一方面隔板70上设置有供电极柱21贯穿的穿孔72，还可以对贯穿端盖20并抵接至加热元件32两端的电极柱21进行保持固定。根据图5和图6所示，隔板70上还设置有通气孔71，是与进气孔22气流连通的，用于供空气以图5所示的方式沿厚度方向流经雾化面后从气流通道52输出。
根据图6所示的优选实施中，通气孔71是偏离中心设置的，具体设置于靠近沿厚度方向的一侧设置，并与雾化面的加热元件32是相对错开的。
进一步在图3至图6所示的实施中，端盖20上设置有凹槽25，该凹槽25用于安装密封圈80，使端盖20与外壳体10之间的缝隙进行密封。并且在实施中，通过该密封圈80与硅胶密封座60之间形成雾化腔室，以上用于汽化液体基质的多孔体31、加热元件32、刚性支撑架50等均被容纳和设置与位于密封圈80与硅胶密封座60之间的雾化腔室内。
进一步在优选的实施中，端盖20朝外壳体10内壁的表面上设置有第一毛细储液槽23，对应刚性支撑架50朝外壳体10内壁的表面上设置有第二毛细储液槽53；以上第一毛细储液槽23和第二毛细储液槽53可以是宽度足够小到对液态介质有毛细吸附作用，比如宽度可以采用0.05到0.2mm之间，优选为0.09到0.15mm之间。
并且在图5所示的优选实施中，以上第一毛细储液槽23和第二毛细储液槽53的数量均为若干，并且是离散的，即是没有相互交叉或者彼此连接的，离散的设置方式可以增加与气流之间通过毛细吸附的作用面积。
在图5所示的优选实施中，第一毛细储液槽23至少部分在支撑臂24的外表面上延伸。第二毛细储液槽53沿宽度方向围绕气流通道52的两侧布置，具有与气流通道52中传输的气溶胶的冷凝液更充分的毛细吸附效果。当然，第一毛细储液槽23和第二毛细储液槽53的空间与气流通道52是气流连通的。
更加优选的，第二毛细储液槽53是朝靠近硅胶密封座60倾斜的方式设置的。
进一步参见图11至图13所示，在又一个可变的实施中，端盖20a和支撑架50a上设置的毛细储液槽可以是相互连通的；具体，
支撑架50a设置有沿周向延伸的第三毛细储液槽，包括沿支撑架50a的周向延伸的若干第一部分54a、以及沿纵长方向与第一部分54a连接的第二部分55a，进而整体连通形成一个整体，具有更大的毛细吸附空间或能力。或者在其他的可变实施中，还可以至部分围绕在支撑架50a的周向的表面上的。其中，第二部分55a的数量可以包括有若干，并且根据图中所示的优选实施，若干第二部分55a沿支撑架50a的纵向方向是相对错开的，以增加对冷凝液的保持的能力降低其在第三毛细储液槽之间的流动。
同样，在端盖20a的外表面上设置的第一毛细储液槽23a同样也包括若干沿周向延伸的第一部分231a、以及沿纵向延伸的第二部分232a，并且是相互连通的。
进一步在图12所示的端盖20a的内壁上还设置有沿纵向延伸的第四毛细储液槽26a。
进一步在更加优选的实施中，以上毛细储液槽与储液腔12是通过硅胶密封座60隔离进而保持非气流连通的。具体，硅胶密封座60可以阻止储液腔12内的液体基质流出、以及阻止液体基质流向第一毛细储 液槽23和第二毛细储液槽53，并阻止气体或气流在储液腔12和雾化腔室之间的流通，进而使储液腔12与雾化腔室及第一毛细储液槽23和第二毛细储液槽53彼此流体隔离，呈非气流连通；并仅能允许气体通过多孔体30的微孔孔隙作为介质通道进入至储液腔12内。
以上设置于端盖20/20a外表面与外壳体10之间保持有一定的间隙，使得端盖20/20a外表面的储液槽一方面是与雾化腔室或者烟气输出通道气流连通的，另一方面能通过间隙的毛细浸润使雾化腔室内的冷凝液传递至端盖20/20a外表面的储液槽内。同时，端盖20/20a的支撑臂24与支撑架50/50a之间也可以保持较小的间隙，在维持于雾化腔室气流连通的同时也能促进冷凝液的浸润和传递。
以上电子烟雾化器，采用在端盖或刚性支撑架上设置可以通过毛细作用吸收冷凝液的储液槽，通过使冷凝液被保持在储液槽内进而阻止冷凝液在抽吸中随着抽吸气流被带出，进而消除了吸食到冷凝液的问题。
