具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
本申请的一个实施例提出一种电子雾化装置，可以参见图1所示，该电子雾化装置包括存储有液体基质并对其进行汽化生成气溶胶的雾化器100、以及为雾化器100供电的电源机构200。
在一个可选的实施中，比如图1所示，电源机构200包括设置于沿长度方向的一端、用于接收和容纳雾化器100的至少一部分的接收腔270，以及至少部分裸露在接收腔270表面的第一电触头230，用于当雾化器100的至少一部分接收和容纳在电源机构200内时与雾化器100的形成电连接进而为雾化器100供电。
根据图1所示的优选实施，雾化器100沿长度方向与电源机构200相对的端部上设置有第二电触头21，进而当雾化器100的至少一部分接 收于接收腔270内时，第二电触头21通过与第一电触头230接触抵靠进而形成导电。
电源机构200内设置有密封件260，并通过该密封件260将电源机构200的内部空间的至少一部分分隔形成以上接收腔270。在图1所示的优选实施中，该密封件260被构造成沿电源机构200的横截面方向延伸，并且优选是采用具有柔性材质例如硅胶制备，进而阻止由雾化器100渗流至接收腔270的液体基质流向电源机构200内部的控制器220、传感器250等部件。
在图1所示的优选实施中，电源机构200还包括沿长度方向背离接收腔270的另一端的用于供电的电芯210，以及设置于电芯210与容纳腔之间的控制器220，该控制器220可操作地在电芯210与第一电触头230之间引导电流。
在使用中电源机构200包括有传感器250，传感器250用于感测抽吸雾化器100时产生的抽吸气流，进而控制器220根据该传感器250的检测信号控制电芯210向雾化器100输出电流。
进一步在图1所示的优选实施中，电源机构200在背离接收腔270的另一端设置有充电接口240，充电接口240用于对电芯210充电。
图2至图3的实施例示出了图1中雾化器100一个实施例的结构示意图，包括：
主壳体10，根据图2至图3所示，该主壳体10大致呈扁形的筒状。主壳体10具有沿长度方向相对的近端110和远端120。其中，根据通常使用的需求，近端110被配置为作为用户吸食气溶胶的一端，在近端110设置有用于供用户抽吸的吸嘴口A。而远端120被作为与电源机构200结合的一端，且主壳体10的远端120为敞口，其上安装有可以拆卸的端盖20，敞口结构用于向主壳体10内部安装各必要功能部件。
进一步在图2至图4所示的具体实施中，第二电触头21是由端盖20的表面贯穿至雾化器100内部的，进而其至少部分是裸露在雾化器100外的，则进而可与第一电触头230通过接触进而形成导电。同时，端盖20上还设置有进气口23，用于在抽吸中供外部空气进入至雾化器100内。
进一步参见图3、图4、图9和图10所示，主壳体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中吸取液体基质并加热雾化液体基质的雾化组件。其中，雾化组件通常包括用于吸取液体基质的毛细导液元件、以及结合于导液元件的加热元件，加热元件在通电期间加热导液元件的至少部分液体基质生成气溶胶。在可选的实 施中，导液元件包括柔性的纤维，例如棉纤维、无纺布、玻纤绳等等，或者包括具有微孔构造的多孔材料，例如多孔陶瓷；加热元件可以是通过印刷、沉积、烧结或物理装配等方式结合在导液元件上，或缠绕在导液元件上的。
进一步在图3、图4所示的优选实施中，雾化组件包括：用于吸取和传递液体基质的多孔体30、以及对多孔体30吸取的液体基质进行加热汽化的加热元件40。具体：
在图9和图10所示的剖面结构示意图中，主壳体10内设有沿轴向设置的烟气传输管11。主壳体10内还设有用于存储液体基质的储液腔12。在实施中，该烟气传输管11至少部分储液腔12内延伸，并由烟气传输管11与主壳体10内壁之间的空间形成储液腔12。该烟气传输管11相对近端110的第一端与吸嘴口A连通、相对远端120的第二端与多孔体30的雾化面310与端盖20之间界定形成的雾化腔室340气流连接，从而将加热元件40汽化液体基质生成并释放至雾化腔室340的气溶胶传输至吸嘴口A处吸食。
参见图3、图4和图9所示的多孔体30的结构，该多孔体30的形状被构造成在实施例中可大致呈但不限于块状结构。根据本实施例的优选设计，其包括呈拱形形状，其具体结构可参见专利申请CN212590248U所记载。大体的功能构造上，多孔体30具有沿主壳体10的轴向方向朝向端盖20的雾化面310。其中，在使用中多孔体30背离雾化面310的一侧与储液腔12流体连通进而可吸收液体基质，多孔体30内部所具有的微孔结构再将液体基质传导至雾化面310雾化形成气溶胶，并从雾化面310释放至由雾化面310与端盖20之间界定的雾化腔室340中。
当然，加热元件40是形成于雾化面310上的，并且在装配之后，第二电触头21抵靠于加热元件40进而为加热元件40供电。
进一步参见图3至图5，为了辅助对多孔体30的安装固定、以及对储液腔12进行密封，在主壳体10内还设有柔性密封套50、支架60和柔性的密封元件70，既对储液腔12的敞口进行密封，还将多孔体30固定保持在内部。其中：
具体结构和形状上，柔性密封套50大体呈中空的筒状，内部中空用于容纳多孔体30，并通过紧配的方式套设在多孔体30外。
刚性的支架60则对套设有柔性密封套50的多孔体30进行保持。在一些实施例中刚性的支架60可包括大致呈下端为敞口的环状形状，并设置有保持空间64，保持空间64用于容纳并保持柔性密封套50和多孔体30。柔性密封套50一方面可以在多孔体30与支架60之间对它们 之间的缝隙进行密封，阻止液体基质从它们之间的缝隙渗出，另一方面，柔性密封套50位于多孔体30与支架60之间，对于多孔体30被稳定容纳在支架60内而避免松脱是有利的。
柔性密封元件70设置于储液腔12与支架60之间，且其外形与主壳体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。进一步为了防止柔性材质的柔性密封元件70的收缩变形影响密封的紧密性，则利用以上支架60容纳在柔性密封元件70内对其提供支撑。
在抽吸过程中气溶胶的输出路径上，相关的结构参见图3和图4所示，柔性密封元件70上设置有供烟气传输管11下端插接的第一插孔72，对应支架60上设置有第二插孔62，支架60上与主壳体10相对的一侧设置有将雾化面310与第二插孔62气流连通的气溶胶输出通道63。在安装之后，完整的抽吸气流路径参见图3中箭头R2所示，外部空气经由端盖20上的第一进气口23进入至雾化腔室340，而后携带生成的气溶胶由气溶胶输出通道63流向第二插孔62后，经第一插孔72向烟气传输管11输出。
液体基质的传递路径上，具体参见图3、图4和图11所示，支架60上设置有用于供储液腔12内的流向保持空间64的第二导液孔61；柔性密封套50上进一步设置有与第二导液孔61相对的第三导液孔51，以使液体基质能透过第三导液孔51传递至多孔体30的表面上进而被吸收，如图11中箭头R1所示。
在进一步为了防止雾化器100在被用户使用之前储液腔12内的液体基质渗漏，本申请的又一个优选的实施例中，参见图5至图11所示；雾化器100中注液后的主壳体10与端盖20具有图5/图10中所示的第一装配位置和图6/图11中所示的第二装配位置。在第一装配位置中，储液腔12与第二导液孔61之间是被隔离或密封的，而在第二装配位置中储液腔12与第二导液孔61之间是导通的。
在结构上参见图3和图4，主壳体10和端盖20上设置有配合的限位结构，用于在装配过程中的第一装配位置和第二装配位置对柔性密封元件70提供限位。在具体的实施中，限位结构包括：第一卡槽13和第二卡槽14。
具体的，主壳体10具有沿纵向方向依次设置的第一卡槽13和第二卡槽14；其中，第一卡槽13更靠近主壳体10的远端120。以及，端盖20上具有沿纵向方向依次设置的第一卡扣24和第二卡扣25。
当主壳体10与端盖20在图5/图10所示的第一装配位置时，端盖 20上的第一卡扣24与第一卡槽13形成卡合；而第二卡槽14和第二卡扣25处于非结合状态；此时从图中可以看出，第一装配位置时端盖20与主壳体10之间仍然保持有间距80未完全紧密结合。进一步按照图10中箭头R3所示，将端盖20进一步向主壳体10按压，则端盖20的第一卡扣24会进一步卡入至主壳体10的第二卡槽14内，以及端盖20的第二卡扣25会卡入主壳体10的第一卡槽13内，端盖20与主壳体10紧密结合形成图6和图11所示的第二装配位置。
结合具有以上不同的装配位置，进一步雾化器100具有结合以上操作导通或关闭储液腔12的构造。具体在用于密封储液腔12的柔性密封元件70上，设置有：
与第二导液孔61相对的遮挡部分71，并通过该遮挡部分遮挡或密封第二导液孔61，进而阻止储液腔12内的液体基质流入第二导液孔61；
可破裂脆弱区73，在图8所示的优选实施中，被构造成是围绕遮挡部分71的凹槽界定，进而使可破裂脆弱区73具有低于密封元件70其它部分的非常薄的厚度利于其破裂或断裂，例如约0.1mm的厚度。在使用中，该可破裂脆弱区73能够破裂从而使遮挡部分71松脱或掉落，进而导通储液腔12和第二导液孔61，如图11中所示。
进一步为了使可破裂脆弱区73破裂，参见图7和图11所示，主壳体10内还设置有沿纵向延伸的挤压构件112，其形状可以呈薄片或杆状等形状，其具有朝向远端120的自由端，并将该自由端构造成用于挤压遮挡部分71的挤压端111。在生产和使用的操作过程，依次参见图9至图11所示，包括：
S10，参见图9将对储液腔12注液完成后的主壳体10倒置，而后将装配有密封元件70、支架60等的端盖20压入主壳体10的敞口端，直至使端盖20上的第一卡扣24与第一卡槽13形成卡合，装配形成图10中的第一装配位置。此时端盖20与主壳体10之间还保持有一定的间距80未完全紧密结合；同时密封元件70的遮挡部分71与挤压端111抵靠，但可破裂脆弱区73还未破裂，储液腔12与支架60的第二导液孔61之间是隔离或密封的。
S20，在用户需要使用时，进一步将端盖20沿图10中箭头R3所示朝主壳体10压紧，直至端盖20的第一卡扣24卡入至主壳体10的第二卡槽14内，第二卡扣25卡入主壳体10的第二卡槽13内，形成图11所示的第二装配位置。在此过程中，密封元件70的遮挡部分71进一步被挤压端111挤压，使可破裂脆弱区73断裂进而造成遮挡部分71松脱或掉落，从而导通储液腔12与支架60的第二导液孔61，液体基质可沿 箭头R1所示流向多孔体30，而后被加热雾化生成供用户抽吸的气溶胶。
进一步从以上描述和图中可以看出，密封元件70在第一装配位置和第二装配位置均在储液腔12与支架60之间提供密封，已阻止液体基质在它们之间的间隙的渗漏。
进一步根据图8所示，为了使挤压构件112的挤压端111在挤压遮挡部分71具有足够的强度，挤压构件112自身是连接在烟气传输管11的管壁上的。当然，在优选的实施中，带有烟气传输管11和挤压构件112的主壳体10是由可模制材料通过模具成型制备的。
在一些其它的可选变化实施中，图12示出了又一个实施例的密封元件70a和支架60a的结构示意图。其中：
支架60a具有第二导液孔61a，以供储液腔12内的液体基质流向多孔体30；
密封元件70a具有与第二导液孔61a相对的第一导液孔74a，以及位于第一导液孔74a内的遮挡部分71a；该遮挡部分71a通过可破裂脆弱区73a连接或保持于第一导液孔74a内。在装配后，遮挡部分71a遮挡或密封第二导液孔61a；并在挤压构件112的挤压端111挤压遮挡部分71a时可破裂脆弱区73a产生断裂，则使遮挡部分71a松脱或掉落，进而打开第二导液孔61a。
在以上所描述的密封元件70/70a之外，还可以采用可扩大的狭缝或切口形成脆弱区，在被挤压构件112的挤压端111挤压时狭缝或切口扩大进而导通储液腔12和第二导液孔61/61a。
图13和图14示出了又一个实施例的雾化器的结构示意图；在主壳体10b的烟气输出管11b上一体形成有挤压构件112b，该挤压构件112b的挤压端111b被构造成尖刺或尖端的形状，便于在挤压中更加容易使密封元件70/70b的可破裂脆弱区73b刺破或碎裂。当然，根据图13所示，该尖刺或尖端的挤压端111b在位置上是与可破裂脆弱区73b相对的，操作过程中挤压端111b抵靠于可破裂脆弱区73b并进行挤压从而使其刺穿或破裂。
图15和图16示出了又一个实施例的挤压构件112c的结构示意图；在该实施例中挤压构件112c主要是呈环状的形状，并基本通过铆压或注塑或过盈等方式围绕结合在烟气输出管11c的下端。挤压构件112c同样具有呈尖端或尖刺形状的挤压端111c，便于在挤压中更加容易使密封元件70/70a的可破裂脆弱区73/73a刺破或碎裂。挤压构件112c具有更小的尺寸或体积，对于提升储液腔12c的空间和储液能力是有利的。
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，但并不限于本说明书所描述的实施例，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。
