在图9所示的具体实施中，多孔体21的长度尺寸约为8～15mm，以及多孔体21的宽度尺寸大约为4～8mm，以及多孔体21的厚度尺寸大约为3～6mm。
进一步参见图9所示，多孔体21具有位于表面211和表面212之间延伸的多孔部分213和多孔部分214；以及由多孔部分213界定表面211、以及由多孔部分214界定表面212。其中，多孔部分213的厚度尺寸L1大于多孔部分214的厚度尺寸L2；多孔部分213的宽度尺寸L3是大于多孔部分214的宽度尺寸L4的。具体的实施中，多孔部分213的厚度尺寸L1大约为2～4mm，以及多孔部分214的厚度尺寸L2大约为1～2mm。以及，多孔部分213的宽度尺寸L3大约为4～8mm，以及多孔部分214的宽度尺寸L4大约为3～6mm。

空腔450沿支撑部分40的厚度方向的两侧是敞开的，在装配后是密闭的，以阻止所搜集的冷凝液渗出。

进一步参见图2至图8所示，电子雾化装置100还包括第一密封元件60，至少部分包围支撑部分40，进而在第一壳体10之间提供密封。第一密封元件60是由柔性材质制备的，例如硅胶、弹性聚合物等。第一密封元件60围绕支撑部分40的筒状；并且第一密封元件60的延伸长度基本是与支撑部分40的延伸长度相同的，进而第一密封元件60能基本完全地在长度上包围支撑部分40。
以及参见图3至图5、图9至图11所示，第一密封元件60包括：
端壁610，垂直于第一密封元件60的纵向方向布置；在装配后是端壁610是抵靠于支架30的第一端310的，即由支撑部分40提供支撑的；
周侧壁620，由端壁610延伸形成，大概呈环形形状，以包围支撑部分40。周侧壁620具有背离端壁610的自由端，并且自由端是敞开的，支撑部分40通过该敞开的自由端伸入至周侧壁620内。
第一密封元件60的端壁610上设置有：
插接孔61；在装配中，插接孔61是与支撑部分40的插接孔42相对的。在装配后，气溶胶输出管11依次穿过插接孔61和插接孔42。以及使第一密封元件60至少部分在气溶胶输出管11与支撑部分40的插接孔42之间提供密封。
第一密封元件60的端壁610上还设置有：
导液孔65，装配中与支架40的液体通道44位于上端的端口相对；进而供储液腔12的液体基质通过该导液孔65流入液体通道44。
第一密封元件60的周侧壁620在装配后位于第一壳体10与支架40之间，以在它们之间提供密封。第一密封元件60的周侧壁620上设置有：
密封凸筋641，靠近端壁610，并围绕周侧壁620；在装配后密封凸筋641在靠近储液腔12的敞口端提供密封，以使储液腔12内的液体基质基本仅能通过导液孔65离开储液腔12。
以及，密封凸筋642，靠近周侧壁620背离端壁610的自由端，并围绕周侧壁620。装配后，密封凸筋642是由支撑部分40的连接端部410支撑的，以在靠近连接端部410处和第一壳体10之间提供密封。
第一密封元件60的周侧壁620上设置有：
位于厚度方向的两侧的开口66；在装配后，其中一侧的开口66与支撑部分40的开口48是相对的，另一侧的开口66是与支撑部分40的开口49是相对的。以及开口66的宽度尺寸d3是小于支撑部分40的开口48的宽度的，以及开口66的宽度尺寸d3基本是等于支撑部分40的开口49的宽度尺寸d2的。
以及在具体的实施中，开口66沿第一密封元件60的纵向方向的延伸尺寸是覆盖支撑部分40的窗口43的；或者开口66至少部分沿支撑部分40的厚度方向是与支撑部分40的窗口43相对或重合的；进而对防止遮挡或堵塞窗口43影响气溶胶从窗口43的输出是有利的。
进一步在更加优选的实施中，参见图5、图6和图8所示，支撑部分40还设置有靠近上端的通气孔45；该通气孔45的下端是通过支撑部分40的外表面上的凹槽46与雾化腔室441气流连通的，通气孔45的上端是朝向储液腔12的。对应地，第一密封元件60还具有由端壁610出的柱状部分67。根据图中所示，柱状部分67是柱状形状；在装配后，柱状部分67是从上端伸入至通气孔45内的。
在实施中，通气孔45具有大约3～10mm的延伸长度；通气孔45具有3～6mm的内径。柱状部分67具有大约3mm～10mm的长度，以及大约3～6mm的外径。以及，通气孔45的内表面上设置有轴向延伸的槽，以在它们装配之后保持它们之间具有缝隙或气隙。从而，雾化腔室441内的空气能沿图6和图8中箭头R3所示，依次穿过凹槽46、通气孔45与柱状部分67之间的缝隙或气隙进入至储液腔12内，以向储液腔12内补充空气缓解储液腔12的负压。
进一步参见图7和图8所示，通气孔45、第一密封元件60的柱状部分67均是与液体通道44错开的。柱状部分67是由第一密封元件60的端壁610延伸出的。具体地，第一密封元件60的端壁610上界定有导液孔65的壁671，柱状部分67是由该壁671延伸出的。以及第一密封元件60还具有沿宽度方向比导液孔65更靠近端部的避让孔672，以用于供由通气孔45与柱状部分67之间的缝隙或气隙进入的空气通过该 避让孔672进入储液腔12内。在实施中，避让孔672是弯曲的弧形。并且避让孔672与导液孔65是隔离的；以及避让孔672的横截面积小于导液孔65的面积。
进一步参见图2、图3、图5、图10和图11，电子雾化装置100还包括：
柔性的第二密封元件70，在装配后第二密封元件70位于支撑部分40的空腔440内，包围雾化组件/多孔体21；以在雾化组件/多孔体21和支撑部分40之间提供密封。
具体地，第二密封元件70的构造包括：
上端壁710，垂直于电子雾化装置100/支架30/支撑部分40的纵向方向布置；
周侧壁720，由上端壁710沿电子雾化装置100/支架30/支撑部分40的纵向方向延伸形成；基本是环形的形状。
在装配后，周侧壁720从雾化组件/多孔体21的周向围绕雾化组件/多孔体21。
上端壁710上设置有避让孔72，以及围绕避让孔72的密封凸筋71。在使用中，由液体通道44流出的液体基质通过该避让孔72流向多孔体21的表面211上。
在实施中，密封凸筋71闭合的环形。以及在装配后，上端壁710的密封凸筋71是抵靠于支撑部分40的分隔壁420的。进而以阻止由液体通道44流出的液体基质从雾化组件/多孔体21与支撑部分40之间的缝隙渗漏。
在更加优选的实施中，参见图11所示，分隔壁420具有下表面421；该下表面421是朝向分隔壁430/支撑部分50/远端120的。或者，该下表面421是背离储液腔12/近端110的。在装配后，第二密封元件70的上端壁710是抵靠在该分隔壁420的下表面421的。
以及根据图11所示，下表面421是倾斜布置的。具体地，下表面421呈与支架30/支撑部分40/电子雾化装置100的纵向方向具有角度的倾斜设置。具体地，图11中下表面421与支架30/支撑部分40/电子雾化装置100的纵向方向的角度α介于5～30°；更加优选地，角度α介于5～10°。
对应地，第二密封元件70的上端壁710的上表面也是倾斜布置的。第二密封元件70的上端壁710的上表面与纵向方向的角度α也是于5～30°；更加优选地，角度α介于5～10°。
参见图11所示，在装配中当包裹雾化组件/多孔体21的第二密封 元件70沿图中箭头P1所示，从支撑部分40的开口48沿厚度方向移动接收至空腔440内时，由于上端壁710的上表面与分隔壁420的下表面421的斜面接触，越往里压则越紧，对于使密封凸筋71与分隔壁420的下表面421过盈紧配提升密封效果是有利的。
或者在又一些常规的实施中，上端壁710的上表面和/或分隔壁420的下表面421是垂直于纵向方向布置的，即非倾斜布置的。
