在又一个更加优选的实施中，参见图7所示，外支架70的第二支撑部分72内设置有与第二导液元件30的第一部分31的形状相适配的装配腔721，用于辅助第二导液元件30在外支架70内的装配定位。同时，在装配腔721的壁上设置有沿主壳体10的厚度方向延伸的第五毛细沟槽722，该第五毛细沟槽722沿主壳体10的宽度方向位于加热元件40或第一部分31被加热元件40围绕部分的两侧。最终在靠近被加热元件40加热的雾化区域的部位与第一部分31之间形成间隙或空间，用于吸收和缓存液体基质，阻止液体基质直接较快地传递至被加热元件40围绕部分减缓炸油。
在可选的实施中，第五毛细沟槽722设计中具有0.5mm的宽度和0.46mm的深度。
在又一个优选的实施中，第一导液元件50是采用有具有弹性的机多孔材料制备的，呈现适度的柔韧性和刚性。在实施中，第一导液元件50具有小于主壳体10或界定储液腔12的材料、并大于第二导液元件30的材料的弹性模量或刚度。具体是具有邵氏硬度20～70A的硬质人造棉。在可选的实施中，第一导液元件50是包括取向聚酯纤维的硬质人造棉、或者由丝状聚氨酯的硬质人造棉或人造泡棉等。以上第一导液元件50具有介于通常柔性植物棉/无纺布(邵氏硬度小于20A)与刚性多孔陶瓷/微孔金属(邵氏硬度大于80A)之间的硬度或柔性，因而结构稳定在吸收和浸润液体基质后具有极低的膨胀，则装配后第一导液元件50与外壳体10的内壁/烟气输出管11的管壁是介于柔性接触和刚性接触之间接触，一方面其利用自身的柔性可以独立地对储液腔12进行密封，另一方面其又具有一定的硬度可以容易地被固定和保持。具体根据 以上图中所示，第一导液元件50的形状与储液腔12下端的敞口基本是适配的，进而可以用于覆盖、封堵和密封储液腔12。
在更加优选的实施中，第一导液元件50具有50～70A的邵氏硬度，大约等同于热塑性弹性体或硅胶。
图8示出了以上硬度的第一导液元件50的表面或截面的形貌示意图；第一导液元件50大致是呈椭圆形的形状，配合烟气传输管11的第一插接孔51也是椭圆形的形状。第一导液元件50是由基本成沿长度方向取向排列的例如聚乙烯和/或聚丙烯的取向纤维制备的，例如图9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。并且采用以上有机纤维制备的第一导液元件50，在制备的过程中使纤维材料之间保留充足的空隙，进而既能传递液体基质，还能使第一导液元件50具有适当的柔韧性。具有以上取向纤维的第一导液元件50呈各向异性的。具体一方面具有至少沿长度方向的抗折强度大于沿宽度方向的抗折强度；或者另一方面，具有沿长度方向的导液速率大于沿宽度方向的导液速率。
同时在图8中，第一导液元件50的表面或内部具有沿长度方向延伸的纹路52；具体，纹路52是由以上取向纤维通过辊筒压制等的纺织工艺制备的，并且在制备的过程中通过辊筒压制或水刺工艺等使部分纤维之间的间距加大，从而在间距加大的位置形成肉眼可见的凹痕，宽度小于1mm，大约介于0.1～0.5mm；进而由以上凹痕在第一导液元件50表面或内部形成纹路52，对于液体基质的传递和保持、以及提升硬质性能是有利的。
以上实施例的图8所示的第一导液元件50中，第一导液元件50具有长度d4为16.4mm、宽度d5为7.80mm、以及厚度2.0mm。
进一步参见图4至图6所示，雾化器100还包括供空气进入至储液腔12内的气压平衡通道，以向储液腔12内补充空气进而缓解储液腔12由液体基质的消耗引起的负压。具体在实施中，在图6中是由第一支撑部分71的侧壁上设置有凹陷结构713，进而使第一支撑部分71与外壳体10的内壁之间保持间隙；同时，第一导液元件50的周侧壁的两侧具有平直部分52，进而使第一导液元件50的平直部分52与外壳体10的内壁之间也同样保持间隙；进而当储液腔12内的负压超过一定阈值时，窗口或镂空73内的空气能沿着图5中箭头R3所示，依次穿过凹陷结构713所界定的空隙、以及平直部分52所界定的空隙后进入至储液腔12内。当然在以上实施中，窗口或镂空73内的空间一方面是由于第二部分32与内支架60之间的间隙等与雾化腔室连通的；又一方面，窗口或镂空73内的空间还可以是通过外支架70与外壳体10之间的间隙进而与外部大气连通的。
图10至图12示出了又一个实施例的雾化器100a的示意图；包括：
主壳体10a，内部设置沿纵向延伸的烟气输出管11a、以及由烟气输出管11a与主壳体10a的内壁界定的储液腔12a；
第二导液元件30a，具有沿主壳体10a的宽度方向延伸的第一部分31a、以及由第一部分31a沿主壳体10a的纵向方向延伸出的第二部分32a；第二部分32a通过与片状或块状的第一导液元件50a与储液腔12a流体连通；其中，第二导液元件30a是常规的柔性的植物棉，第一导液元件50a是由以上取向纤维制备并呈硬质形态的；
加热元件40a，围绕第一部分31a的至少部分，进而加热第一部分31a内的至少部分液体基质生成气溶胶；
外支架70a，呈中空的杯状或筒状的形状，其内部用于保持第二导 液元件30a，并界定有围绕第一部分31a的雾化腔室；加热元件40a加热生成的气溶胶释放至该雾化腔室后再输出至烟气输出管11a；同时，由外支架70a靠近储液腔12a的上端对第一导液元件50a提供支撑；
端盖20a，用于对主壳体10a的敞口端进行密封，并且其上设置有第二电触头21a和第一进气口22a；
第二电触头21a，由端盖20a贯穿至雾化器100a内，用于为加热元件40a供电。
进一步参见图12和图13所示，外支架70a内部用于保持第二导液元件30a的保持结构包括：
布置于内底壁上沿主壳体10a的宽度方向延伸的第一保持凹腔71a，用于保持第二导液元件30a的第一部分31a；以及沿主壳体10a纵向方向延伸的第二保持凹腔72a，用于保持第二导液元件30a的第二部分32a。
同样，在第一保持凹腔71a的壁上设置有沿主壳体10a的厚度方向延伸的第五毛细沟槽711a，该第五毛细沟槽711a沿主壳体10的宽度方向位于加热元件40a或第一部分31a被加热元件40a围绕部分的两侧。最终在靠近被加热元件40a加热的雾化区域的部位与第一部分31a之间形成间隙或空间，用于缓存液体基质以阻止液体基质直接较快地流向或传递至被加热元件40a围绕部分，减缓炸油。
在装配后参见图18所示，沿外壳体10a的宽度方向第五毛细沟槽711a与加热元件40a的发热部分即第一螺旋线圈410a和/或第二螺旋线圈420a的距离d6大约为1.5mm左右。
外支架70a的外壁上还设置有沿周向延伸的第一凸筋75a和第二凸筋76a，用于对外支架70a与主壳体10a之间的间隙进行密封。其中，第一凸筋75a靠近端盖20a，第二凸筋76a靠近第一导液元件50a。
外支架70a还设置有朝向端盖20a的第二进气口77a，用于供由第一进气口22a进入的外部空气进入至外支架70a内的雾化腔室中。在图13所示的实施中，外支架70a的内壁上设置有若干沿纵向延伸的第一凸棱73a，并由第一凸棱73a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731a。在实施中，第一凸棱73a大约具有0.5～1.5mm的宽度，毛细沟槽731a的宽度小于2mm。
在图12至图14、图16和图17所示的优选实施中，烟气输出管11a背离吸嘴口A的进气端设置有第一缺口111a；该第一缺口111a的数量优选是两个，是沿主壳体10a的厚度方向相对设置的。配合该第一缺口111a，外支架70a内设置有至少部分延伸至第一缺口111a内的第二凸棱74a。装配后，第二凸棱74a的两侧表面与第一缺口111a的两侧表面是不接触的，并且根据图2中第二凸棱74a与第一缺口111a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11a内坠落或流动至进气端的冷凝液吸附引导至外支架70a的雾化腔室内，进而避免冷凝液在烟气输出管11a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13，为了保证第二凸棱74a能延伸至烟气输出管11a的第一缺口111a内，第二凸棱74a的凸起高度大于第一凸棱73a的凸起高度、宽度与第一凸棱73a相同。
在图14所示的实施中，烟气输出管11a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10a的宽度方向为长轴B1、以主壳体10a的厚度方向为短轴B2，进而烟气输出管11a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11a的端部设置有靠近主壳体10a宽度方向的至少一侧的第二缺口112a，通过该第二缺 口112a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111a的位置，而后更加便于在第二凸棱74a的配合下引导至雾化腔室内。
在图14所示的优选的实施中，第一缺口111a具有大于第二缺口112a的宽度；实施中的第一缺口111a的宽度大约2.4mm，第二缺口112a的宽度大约1mm。
在图16和图17所示的实施中，烟气输出管11a的具有靠近第一缺口111a的倾斜管壁113a；在使用中，烟气输出管11a内壁上的气溶胶冷凝液，沿图17中箭头R4所示，由倾斜管壁113a朝第一缺口111a引流，而后由第二凸棱74a与第一缺口111a形成的毛细通道吸附至第二凸棱74a表面后向下流动至外支架70a内的雾化腔室内。并且在图12和图17中均可以看出，第二凸棱74a与第一缺口111a表面均是不接触的。
在使用中，随着液体基质的消耗，储液腔12a内的负压会逐渐增大，影响液体基质顺畅地离开储液腔12a向第二导液元件30a传递；进而雾化器100a内设置有用于向储液腔12a内补充空气的气压平衡通道，减缓储液腔12a内的负压保证液体基质的顺畅传递。具体参见图13至图15，气压平衡通道包括依次连通的两个通道部分，即图13中箭头R31所示的第一通道部分和图15中箭头R32所示的第二通道部分；具体：
主壳体10a靠近宽度方向的两侧的内壁上设置有至少一个第三凸棱14a，具体在图14中第三凸棱14a的数量是两个，并在它们之间保留一定的间距141a。配合该间距141a，在结构设置上图11中硬质的第一导液元件50a的周侧壁具有平直部分52a，在装配之后平直部分52a是抵靠在第三凸棱14a上的，进而界定和保持间距141a不被填充或堵塞；
进一步外支架70a靠近第一导液元件50a的表面上设置有空气凹槽 79a，在图13中空气凹槽79a是位于外支架70a靠近宽度方向的两侧端部的；该空气凹槽79a一侧是与外支架70a内部的空间即雾化腔室连通、另一侧是与以上间距141a连通的，进而雾化腔室内的空气能沿图13中箭头R31穿过空气凹槽79a后，再沿图15中箭头R32所示由间距141a进入至主壳体10a的储液腔12a内，缓解或消除储液腔12a内的负压。
在图14和图15所示的优选实施中，主壳体10a内还设置有若第四凸棱13a，用于在装配后抵靠和夹紧第一导液元件50a。
图19示出了加热元件40a又一个视角示意图，包括沿长度方向相对设置的第一电引脚41a和第二电引脚42a、以及在第一电引脚41a和第二电引脚42a之间延伸的第一螺旋线圈410a和第二螺旋线圈420a。在实施中，第一螺旋线圈410a和第二螺旋线圈420a是同时由第一电引脚41a和第二电引脚42a供电进而呈并联的。在结构上，第一螺旋线圈410a和第二螺旋线圈420a是紧靠并排在一起的。在可选实施中，第一螺旋线圈410a和第二螺旋线圈420a具有大约3～10个匝数或绕组、以及大约4～7mm的延伸长度，在图19中它们具有5个匝数或绕组、以及6.5mm的设计长度。
根据图19中所示，第一螺旋线圈410a和第二螺旋线圈420a它们不是沿径向方向重叠设置的，而是沿轴向方向是并列或错开的，至少它们各自在装配后延第一部分31a的延伸方向各自相对于第一部分31a的位置不同，进而则与第一部分31a具有更大的接触面积发热效率。
第一电引脚41a和第二电引脚42a所采用的导线材料具有大于第一螺旋线圈410a和第二螺旋线圈420a所采用的导线材料的直径；即第一电引脚41a和第二电引脚42a是采用相对粗的导线制备的，第一螺旋线圈410a和第二螺旋线圈420a是采用相对细的导线制备的，进而便于它们的两端与第一电引脚41a和第二电引脚42a连接。具体实施中，第一 电引脚41a和第二电引脚42a是采用直径为约1.5mm的导线制备的，第一螺旋线圈410a和第二螺旋线圈420a是采用0.4mm的导线制备的。
在可选的实施中，第一螺旋线圈410a和第二螺旋线圈420a采用适合的电阻性金属或合金制备，例如铁铬铝、镍铬合金等，具有相对大的电阻温度系数；第一电引脚41a和第二电引脚42a提供电引脚的功能，采用导电性能较高电阻率低的金属或合金制备，例如金、银、铜等或者是通过在丝状基体外表面形成前述金属镀层制备的细长引脚。
进一步参见图19所示，第一电引脚41a包括环状支撑部分411a，以及电连接部分412a；其中，
环状支撑部分411a与第一螺旋线圈410a和第二螺旋线圈420a连接，并且它们的螺旋尺寸例如外径或内径是基本相同的；进而在装配中，环状支撑部分411a也能围绕第二导液元件30a的第一部分31a，进而在装配之后由第一电引脚41a的环状支撑部分411a对第二导液元件30a的第一部分31a提供支撑。电连接部分412a贯穿至外支架70a外便于与第二电触头21a抵靠或焊接。
进一步参见图18所示，在装配后加热元件40a的第一螺旋线圈410a和第二螺旋线圈420a，是不与外支架70a的内壁和/或第一保持凹腔71a的壁接触的；而是通过第一电引脚41a的环状支撑部分411a保持在外支架70a的内壁和/或第一保持凹腔71a的壁上，从而对加热元件40a的支撑；在工作中，第一电引脚41a和第二电引脚42a具有相比第一螺旋线圈410a和第二螺旋线圈420a具有更低的温度，避免对外支架70a造成热损伤。
进一步参见图10、图18和图19所示，第一电引脚41a的电连接部分412a呈弯折的钩状；在装配合的结构中，外支架70a具有由内壁贯穿至朝向端盖20a的表面的引线孔781a，以及朝向端盖20a设置的用于 至少部分容纳第二电触头21a的触头孔782a；在装配后，电连接部分412a贯穿引线孔781a后延伸或弯折至触头孔782a内与第二电触头21a形成导电。
当然，第二电引脚42a具有与第一电引脚41a相同的构造、连接和装配。
在可选的实施中，以上加热元件40a具有大约2～4mm的内径，优选为2.3mm～2.6mm；以及加热元件40a具有大约0.5～2欧姆的电阻。
在其他的变化实施中，加热元件40a还可以是网状基材卷绕在第一部分31a外部形成的。或者进一步图20提出了有一个实施例的加热元件40b的示意图，是由一个管状基材41b上通过切削等方形形成缺口或镂孔42b后形成的；进而在使用中围绕第一部分31a并加热生成供吸食的气溶胶。
