除非另有定义，本说明书所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本说明书中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是用于限制本申请。本说明书所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1-图12所示，电子雾化装置100包括吸嘴11、外壳12、底座13、储液壳14、上端盖15、下端盖16、传输管17、储液件18、加热组件19以及电芯20。加热组件19包括基座191和雾化芯192。
吸嘴11具有自嘴端向下延伸的连接管111。
外壳12上下两端均为敞口端。吸嘴11设置在外壳12的上敞口端，底座13设置在外壳12的下敞口端。
储液壳14、上端盖15以及下端盖16设置在外壳12内。
储液壳14大致呈圆柱状。储液壳14上下两端也是敞口端。上端盖15设置在或者封盖于储液壳14的上端，下端盖16设置在或者封盖于储液壳14的下端。
上端盖15和下端盖16均采用密封材质制成，例如硅胶。
参见图5，上端盖15的外壁上具有径向延伸的凸出部151。
位于凸出部151以上的部分上端盖15伸入到吸嘴11内，吸嘴11下端的端面与凸出部151的上表面抵接以形成密封。连接管111与上端盖15的通孔152连通。
进一步地实施中，上端盖15的上表面(或者背向储液腔的表面)具有收容槽153，吸液件A设置在收容槽153中，吸液件A具有供气流穿过的通孔；这样，吸液件A可吸取吸嘴11中冷凝后的液体基质，进而防止冷凝后的液体基质被使用者抽吸。
位于凸出部151以下的部分上端盖15伸入到储液壳14内。该部分上端盖15的外壁与储液壳14的内壁抵接以形成密封；进一步地，该部分上端盖15的外壁上具有凸块，以与储液壳14的内壁形成良好的密封效果。储液壳14上端的端面与凸出部151的下表面抵接以形成密封。
与此类似的，下端盖16的外壁上具有径向延伸的凸出部161，位于该凸出部161以上的部分下端盖16伸入到储液壳14内。该部分下端盖16的外壁与储液壳14的内壁抵接以形成密封；进一步地，该部分下端盖16的外壁具有凸块，以与储液壳14的内壁形成良好的密封效果。储液壳14下端的端面与凸出部161的上表面抵接以形成密封。
传输管17位于储液壳14中。传输管17的上端保持在上端盖15的通孔152内(即与上端盖15连接)，传输管17的下端收容在基座191内且与雾化芯192上端的端面抵接(即通过基座191与下端盖16连接)。在其它示例中，传输管17的下端可直接与下端盖16连接。
储液壳14的内壁、上端盖15、下端盖16、基座191以及传输管17的外壁之间的间隙界定形成用于储存液体基质的储液腔(未示出)。
储液件18设置在储液腔内。储液件18用于吸附和保持液体基质，优选的采用棉纤维介质制成。储液件18的本体181大致呈圆柱状。储液件18具有供传输管17穿过的通孔182。在一些实施例中，储液件18的侧壁上形成有一卡口(未示出)，使得储液件18呈C型筒状，可便于将储液件18卡装在传输管17外围。
储液件18的上端可以与上端盖15下端的端面保持接触，或者，储液件18的上端与上端盖15下端的端面之间至少部分间隔以形成空腔B。与此类似的，储液件18的下端可以与下端盖16上端的端面保持接触，或者，储液件18的下端与下端盖16上端的端面之间至少部分间隔以形成另一空腔(未示出)。在图1-图12的示例中，储液件18的上端与上端盖15下端的端面之间部分间隔以形成空腔B，而储液件18的下端可以与下端盖16上端的端面保持接触。上述空腔，一方面可增大储液腔的容积，另一方面利于储液件18中困气或者气体的释放。
如果储液件18的外壁与储液壳14的内壁是保持接触的或者过盈配合，在储液件18吸附液体基质之后，由于液体基质的不透气性，当储液件18下端的液体基质被消耗时，储液件18上端易形成负压，进而不利于液体基质的传递。为了避免该问题，在图1-图12的示例中，一方面储液件18的外壁上还具有凹槽183，凹槽183连通储液件18的上下两端，凹槽183界定形成第一气压平衡通道；这样，在储液件18上端形成负压时，储液件18下端的空
气可从凹槽183往上流动(图5中的虚线箭头所示)，以使得储液壳14内外的气压保持平衡，并通过凹槽183使得储液件18上下两端的气压保持平衡，进而利于液体基质的传递。另外凹槽183使得储液件18的外壁与储液壳14的内壁具有一定的间隙，在高温等环境时，该间隙可以保证储液件18具有一定的膨胀空间，避免液体基质从雾化芯192的导液孔191a流出导致的漏液问题。
在本申请另一些实施例中，上端盖15还具有通孔154，通孔154将储液壳14内与外界连通，通孔154界定形成第二气压平衡通道，用于提供将空气排出至所述储液腔外部或者补充至所述储液腔内部的路径；第一气压平衡通道与第二气压平衡通道之间通过空腔B流体导通；在一些可选的示例中，第一气压平衡通道与第二气压平衡通道之间通过储液件18流体导通，也是可行的(储液件18本身具有透气性，例如：当靠近上端盖15的部分储液件18，其吸附的液体基质往下流动之后，通过该部分储液件18连通第一气压平衡通道与第二气压平衡通道)；在一些示例中，第一气压平衡通道与第二气压平衡通道之间直接流体导通，也是可行的。进一步地，由图7-图8可以看出，收容槽153中具有多个空间槽C，空间槽C由收容槽153的部分底面凹陷形成，空间槽C可以收集吸嘴11中冷凝后的液体基质；通孔154一端的开口可以设置在其中一个空间槽C中，多个空间槽C沿着收容槽153的周向方向相互间隔设置，从而能够均匀且充分地收集冷凝液。
在一替代实施例中，如图13所示，凹槽183a可形成在储液件18的内壁上。与前述类似的，通过凹槽183使得储液件18上下两端的气压保持平衡。
需要说明的是，上述凹槽(凹槽183或者凹槽183a)，可以是沿着储液件18的外壁或者内壁轴向延伸，也可以是自储液件18的下端弯曲或者螺旋地延伸到储液件18的上端形成在储液件18的外壁或者内壁上的，也可以不是凹槽，只要使得储液件18的外壁与储液壳14的内壁之间、或者储液件18的内壁与传输管17的外壁之间具有一定的间隙即可。
在另一替代实施例中，如图14所示，储液件18和储液壳14均大致呈圆柱状，储液件18和储液壳14的横截面均为圆环形；考虑传输管17的部分时，储液件18的横截面的直径为d1，储液壳14的横截面的直径为d2，d1<d2。因此，沿储液件18的长度方向的任一横截面内，储液件18未完全占据所述
储液腔，且储液件18的横截面面积是小于储液壳14的横截面面积的。这样，储液件18的外壁与储液壳14的内壁之间具有一定的间隙。通过储液件18的外壁与储液壳14的内壁之间的间隙，使得储液件18上下两端的气压保持平衡。类似的，在储液件18的内壁与传输管17的外壁之间，也可以形成类似的间隙。
在又一替代实施例中，如图15所示，储液件18内具有从储液件18下端延伸至储液件18上端的通孔183c。通孔183c的截面形成不作限定，例如：可以是圆形、椭圆形、三角形、四边形、其它不规则形状等等。通孔183c可以在储液件18内是轴向延伸、弯曲或者螺旋地延伸。通过该通孔183c，进而使得储液件18上下两端的气压保持平衡。
在又一替代实施例中，如图16所示，凹槽183内设置有通气管183d。通气管183d材质的硬度，能够避免储液件18膨胀时被压扁或者坍塌即可。这样，通过凹槽183或者通气管183d，使得储液件18上下两端的气压保持平衡。
需要说明的是，前述示例中的间隙，均可以设置通气管183d。即，通气管183d可以设置在储液件18的外壁与储液壳14的内壁之间、储液件18的内壁与传输管17的外壁之间、插设在储液件18中等等。
需要说明的是，上述凹槽、间隙、通孔、通气管等实施方式，可以组合使用。
对于通孔154，在一替代实施例中，可以通过下端盖16或者传输管17上开设的通孔，将储液壳14内与外界连通，也是可行的。在另一替代实施例中，可以通过上端盖15与传输管17之间的间隙、或者下端盖16与传输管17之间的间隙(传输管17的下端直接与下端盖16连接时)、或者下端盖16与基座191之间的间隙(传输管17的下端通过基座191与下端盖16连接时)、或者上端盖15与储液壳14之间的间隙、或者下端盖16与储液壳14之间的间隙，将储液壳14内与外界连通，也是可行的。与前述类似的，上述通孔、间隙可以组合使用。
基座191的下端保持在下端盖16的通孔162内。基座191内具有收容腔室，用于收容雾化芯192。基座191的侧壁上具有连通储液腔和雾化芯192的导液孔191a，套管(未示出)套设在基座191和传输管17上；套管可吸取储液腔内存储的液体基质，并通过导液孔191a传递至雾化芯192。在其它示例
中，套管也可省略掉。
雾化芯192靠近下端盖16设置。雾化芯192包括导液元件1921和加热元件1922。导液元件1921可以为如棉纤维、金属纤维、陶瓷纤维、玻璃纤维、多孔陶瓷等，优选的为采用棉纤维制成、并被构造成沿着电子雾化装置100的纵向方向延伸的管状结构。加热元件1922为采用电阻材料制成的发热网。加热元件1922可以设置在导液元件1921的内壁上。在其它示例中，雾化芯192可以沿着电子雾化装置100的横向方向延伸布置，例如：加热元件1922缠绕在导液元件1921后，横向穿过基座191；其中，加热元件1922布置在基座191内，导液元件1921的两端可以伸入到储液腔内。
雾化芯192加热生成的气溶胶，通过传输管17、通孔152、吸液件A的通孔、连接管111后(图4中的虚线箭头所示)，从吸嘴11的嘴端传送，进而被用户吸食。
电芯20设置在下端盖16与底座13之间。电芯20提供用于操作电子雾化装置100的电力。电芯20可以是可反复充电电池或一次性电池。优选的采用可反复充电电池。
底座13上设置有进气口，电子雾化装置100外的空气可从该进气口流入电子雾化装置100内，然后从下端盖16的通孔162流入至雾化芯192。进一步地，还可以在底座13上设置气流传感器，用于感测用户的抽吸动作，以启动雾化芯192。
如图17所示，在另一示例中，为了防止吸液件A通过通孔154吸附储液腔中的液体基质，导致液体基质通过上端盖15上的通孔154泄漏，或者为了防止吸液件A破坏上端盖15上的通孔154的液封效果，造成液体基质通过上端盖15上的通孔154泄漏，吸液件A具有缺口槽A1，通过缺口槽A1可以避开上端盖15上的通孔154。
在进一步的实施中，上端盖15的收容槽153中设有空间槽155，空间槽155由凸出于收容槽153底面的挡板构成。通孔154一端的开口设置在空间槽155中，吸液件A设置在空间槽155之外，例如吸液件A设置空间槽155的横向外围。
需要说明的是，若通孔154设置在下端盖16上，下端盖16背向储液腔的表面上也可以设置吸液件A以及对应的缺口槽A1。
如图18-图19所示，在另一示例中，上端盖15面向储液腔的表面上具有多个空间槽D，空间槽D为由储液腔的部分表面凹陷形成，通孔154一端的开口可以设置在其中一个空间槽D中。相邻空间槽D之间通过凸肋156间隔，这样，多个空间槽D沿着收容槽153的周向方向相互间隔，互不连通，从而相互独立。多个空间槽D将上端盖15面向储液腔的表面分隔成不连贯的多个区间，互不连通使得一个空间槽D中的液体基质难以进入另一个空间槽D中，从而能够降低液体基质在上端盖15面向储液腔的表面上的流动速度，且有助于阻断其他空间槽D中的液体基质进入某一空间槽D中，所以有助于减小该空间槽D中的液体基质的量。对于设置通孔154一端的开口的其中一个空间槽D来说，能够使得进入该其中一个空间槽D的液态基质的速度和量受限，所以，有助于阻止液态基质通过通孔154的泄漏。
需要说明的是，若通孔154设置在下端盖16上，下端盖16面向储液腔的表面上也可以如此设置多个空间槽D，而通孔154一端的开口可以设置在其中一个空间槽D中。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但是，本申请可以通过许多不同的形式来实现，并不限于本说明书所描述的实施例，这些实施例不作为对本申请内容的额外限制，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。并且，上述各技术特征继续相互组合，形成未在上面列举的各种实施例，均视为本申请说明书记载的范围；进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
