进一步根据图中所示，烟气传输管11与主壳体10是采用可模制材质一体模制的，进而制备后形成的储液腔12朝远端120呈敞口或开口。

具体，第二导液元件30是内部具有毛细通道的毛细元件，通过毛细浸润吸收和传递液体基质。例如在一些实施中，第二导液元件30是柔性的条带或杆状的纤维材料制备的毛细元件，例如棉纤维、无纺布纤维、海绵体等的毛细元件。或者在又一些变化的实施中，第二导液元件30是内部具有毛细通道的多孔陶瓷体、泡沫金属等的毛细元件。在使用中，第二导液元件30的第二部分32用于吸取液体基质后通过毛细浸润传递至第一部分31；加热元件40被构造成至少部分围绕第一部分31，并加热第一部分31的至少部分液体基质生成气溶胶。根据图3至图5中所示，加热元件40呈螺旋发热丝的构造，材质可以采用电阻性金属例如铁铬铝合金、镍铬合金等。
在可选的实施中，图5中第二导液元件30的第一部分31的延伸长度大约为9mm，第二部分32的延伸长度大约为7.5mm。加热元件40的内径大约在2.3～2.6mm范围。
在实施中，第一导液元件50是一层沿主壳体10的横截面方向延伸的片状或块状的有机多孔纤维。在装配后，第一导液元件50靠近储液腔12的上表面与储液腔12相对并用于吸取液体基质、背离储液腔12的下表面向接触的第二导液元件30的第二部分32传递液体基质，如图5中箭头R1所示。并且第一导液元件50上设置有供烟气传输管11贯穿的第一插接孔51。
在具体的实施中，第一导液元件50采用138#硬质合成有机高分子纤维棉，具有0.1～0.9mg/mm3的密度；整体第一导液元件50重量约为0.04～0.06g。第一导液元件50是由基本成沿长度方向取向排列的取向纤维制备的，例如图6中示出了一个实施例中具有取向排列的聚丙烯纤维的微观形貌图，通过取向纤维在第一导液元件50的长度方向上排布使在第一导液元件50呈现较强的抗弯折力进而呈硬质的特点。
进一步参见图7和图8所示，支架70内部具有用于收容第二导液元件30 的凹腔，凹腔包括：
布置于内底壁上沿主壳体10的宽度方向延伸的第一保持凹腔71，用于收容第二导液元件30的第一部分31；以及沿主壳体10纵向方向延伸的第二保持凹腔72，用于收容第二导液元件30的第二部分32。
在图7和图8所示的优选实施中，支架70优选是由柔性材质例如硅胶、热塑性弹性体制备的，支架70的外壁表面上设置有沿周向延伸的第一凸筋76和第二凸筋75。在实施中，第一凸筋76和第二凸筋75用于对支架70与主壳体10之间的间隙进行密封。
在抽吸过程中的气流路径设计上，参见图3所示的实施中，支架70还设置有朝向端盖20的第二进气口77，用于供由第一进气口22进入的外部空气进入至支架70内的雾化腔室中；而后再携带雾化腔室中的气溶胶由贯穿第一插接孔51的烟气传输管11输出。
进一步根据图7和图8所示，支架70的内壁上设置有若干沿纵向延伸的凸棱73，并由凸棱73之间形成可以吸附和保持雾化腔室内的气溶胶冷凝液的毛细沟槽731。在实施中，凸棱73大约具有0.5～1.5mm的宽度，毛细沟槽731的宽度小于2mm。
进一步参见图7、图8、图9、图11和图12所示，烟气输出管11背离吸嘴口A的进气端设置有第一缺口111；该第一缺口111的数量优选是两个，是沿主壳体10的厚度方向相对设置的。配合该第一缺口111，支架70内设置有至少部分延伸至第一缺口111内的凸棱74。装配后，凸棱74的两侧表面与第一缺口111的两侧表面是不接触的，并且根据图12中凸棱74与第一缺口111的两侧表面之间保持有一定的间距。进一步控制该间距低于2mm，进而在它们之间形成毛细作用的毛细通道。由该毛细通道的毛细作用力将烟气输出管11内坠落或流动至进气端的冷凝液吸附引导至支架70的雾化腔室内，进而避免冷凝液在烟气输出管11的内聚集形成液柱，缓解或消除抽吸到冷凝液的问题。
根据图7和图8所示，为了保证凸棱74能延伸至烟气输出管11的第一缺口111内，凸棱74的凸起高度大于凸棱73的凸起高度、宽度与凸棱73相同。进一步在图8所示的优选实施中，凸棱74的凸起高度是变化的，具体是沿纵向方向上端部分比其他部分的凸起高度要更高。
在图9所示的实施中，烟气输出管11的横截面形状是椭圆形的形状；并且 椭圆形的形状是以主壳体10的宽度方向为长轴B1、以主壳体10的厚度方向为短轴B2，进而烟气输出管11内的冷凝液更加倾向于聚集在长轴B1的曲率较大的端部。进而烟气输出管11的端部设置有靠近主壳体10宽度方向的至少一侧的第二缺口112，通过该第二缺口112使长轴B1的曲率较大的端部呈镂空的空间，进而消除冷凝液在此处的聚集而转向更多地聚集至靠近第一缺口111的位置，而后更加便于在凸棱74的配合下引导至雾化腔室内。
在图9所示的优选的实施中，第一缺口111具有大于第二缺口112的宽度；实施中的第一缺口111的宽度大约2.4mm，第二缺口112的宽度大约1mm。
在图11和图12所示的实施中，烟气输出管11的具有靠近第一缺口111的倾斜管壁113；在使用中，烟气输出管11内壁上的气溶胶冷凝液，由倾斜管壁113朝第一缺口111引流，而后由凸棱74与第一缺口111形成的毛细通道吸附至凸棱74表面后向下流动至支架70内的雾化腔室内。并且在图5和图12中均可以看出，凸棱74与第一缺口111表面均是不接触的。
在使用中，随着液体基质的消耗，储液腔12内的负压会逐渐增大，影响液体基质顺畅地离开储液腔12向第二导液元件30传递；进而雾化器100内设置有用于向储液腔12内补充空气的气压平衡通道，减缓储液腔12内的负压保证液体基质的顺畅传递。具体参见图7至图10，气压平衡通道包括依次连通的两个通道部分，即图7和图8中箭头R31所示的第一通道部分和图10中箭头R32所示的第二通道部分；具体：
主壳体10靠近宽度方向的两侧的内壁上设置有至少一个凸棱14，具体在图9和图10中凸棱14的数量是两个，并在它们之间保留一定的间距141。配合该间距141，在结构设置上图3中硬质的第一导液元件50的周侧壁具有平直部分52，在装配之后平直部分52是抵靠在凸棱14上的，进而界定和保持间距141不被填充或堵塞；
进一步支架70靠近第一导液元件50的表面上设置有空气凹槽79，在图7和图8中空气凹槽79是位于支架70靠近宽度方向的两侧端部的；该空气凹槽79一侧是与支架70内部的空间即雾化腔室连通、另一侧是与以上间距141连通的，进而雾化腔室内的空气能沿图7和图8中箭头方向R31穿过空气凹槽79后，再沿图10中箭头方向R32由间距141进入至主壳体10的储液腔12内，缓解或消除储液腔12内的负压。
在图8和图9所示的优选实施中，主壳体10内还设置有若干凸棱13，用于在装配后从第一导液元件50的上表面抵靠和压紧第一导液元件50。

参见图7和图8，第二保持凹腔72的内壁上具有沿纵向方向由上端延伸至第二沟槽711的第一沟槽722；该第一沟槽722用于吸附和缓存在空气补偿过程中由气压平衡通道的第二通道部分渗出的液体基质，同样可以调节在第二部分32表面流动的液体基质的效率。从图8可以看出，第一沟槽722的上端是与空气凹槽79连通的；进而当储液腔12内的液体基质逆着箭头R32所示的方向渗流至空气凹槽79内时，能被吸附至第一沟槽722内并向下流动，如图13中箭头R4所示。

在该实施中，第一沟槽722的延伸长度是大于第二部分32的，至少是由空气凹槽79一直延伸至第一保持凹腔71内的，并且还至少部分是与第一部分31的表面毗邻的。进而在使用中，第一沟槽722能直接将液体基质供应至第一部分31。
进一步参见图7和图8所示，空气凹槽79是由支架70上端围绕第二保持凹腔72的凸起721相互界定的。根据图中所示，空气凹槽79至少部分是弯曲的并围绕第二保持凹腔72的凸起721的。

进一步参见图36所示，支架70d沿厚度方向的两侧壁上具有纵向延伸的窗口76d，在装配后该窗口76d与主壳体10d的内壁之间界定输出通道。具体，该窗口76d沿纵向延伸的的长度至少覆盖由第二导液元件30d的雾化面310d界定的雾化腔室340d，进而使由第二进气口77d进入至雾化腔室340d的空气能进入窗口76d与主壳体10d的内壁之间界定的输出通道内；而后沿图中箭头R2所示跨过第三导液元件80d的U形开口输出至烟气输出管11d。
进一步参见图36，在该实施例中，支架70c毗邻第一导液元件50d的表面上设置有凹槽79d，该凹腔与箭头R2所示的输出通道是气流连通的。进而在装配后，当储液腔12d内的负压超过一定的阈值范围时，空气能依次穿过图36中箭头R31所示由凹槽79d界定的第一通道部分、以及由第一导液元件50d周侧壁的平直部分52d与主壳体10d内壁之间界定的第二通道部分进入至储液腔12d 以缓解负压。
