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。
本申请提出一种电子雾化装置，可以参见图1所示，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，并且是采用具有柔性材质制备，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还包括沿长度方向靠近相对于接收腔270的另一端的电芯210，用于供电；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，用于感测用于通过雾化器100的吸嘴盖20进行抽吸时产生的抽吸气流，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，用于通过与外部的充电设备连接之后对电芯210充电。
图2示出了本申请一个实施例中雾化器100的具体的结构示意图；在该实施例中，雾化器100包括：
整体呈细长的扁形形状，其具有沿长度方向相背的近端110和远端120。在使用中，近端110作为用户嘴部抽吸使用的一端、远端120是接收于电源装置200的一端。在外部构造上包括有：
主壳体10，呈中空的筒状形状，靠近远端120的端部为敞口；
端盖20，布置在雾化器100的远端120，并对主壳体10的敞口进行封闭，进而共同形成完成的雾化器100外壳。在材质采用中，端盖20采用不锈钢材质，进而当雾化器100至少部分接收于电源装置200的内时，端盖20能与电源装置200的磁性件形成磁性吸附，进而使雾化器100稳定保持在电源装置200内。
进一步根据图2所示，雾化器100的第二电触头21由远端120贯穿至内部，并至少部分是裸露在端盖20表面的，进而在使用中便于与电源装置200形成导电。同时，雾化器100的远端120还设置有进气口22，用于在用户抽吸中供外部的空气进入至雾化器100内。
进一步图3至图5示出了图2中雾化器100的内部结构示意图和部分部件的分解示意图。根据图3和图4中所示，雾化器100还包括：
烟气输出管11，沿主壳体10的轴向延伸，其上端是与位于主壳体 100上端的吸嘴口A气流连通的，进而将雾化器100内生成的气溶胶输出至吸嘴口A吸食；
储液腔12，由烟气输出管11与主壳体10内壁之间的空间形成，用于存储液体基质；
雾化组件30，用于从储液腔12通过毛细浸润吸取液体基质，并对吸取的液体基质加热汽化生成供吸食的气溶胶。具体，雾化组件30包括吸液元件31、以及至少部分围绕吸液元件31的加热元件32。根据图3和图4所示，吸液元件31被构造成沿主壳体10的宽度方向延伸，并且其两端是露出或者是与储液腔12流体连通的，储液腔12内的液体基质沿图3中箭头R1所示由吸液元件31两端被吸收后向内传递。加热元件32围绕或缠绕吸液元件31的至少一部分，用于加热第一吸液元件31内的至少部分液体基质生成供吸食的气溶胶。
在可选的实施中，吸液元件31可以采用或包括多孔陶瓷体、纤维棉、多孔材料等等；加热元件32可以采用电阻性的金属材料，例如铁、镍、铬或它们的合金等等。
进一步参见图3至图5所示，为了便于雾化组件30在主壳体10内的装配和固定，主壳体10内还设有第一支撑件和第二支撑件，且第二支撑件为刚性的支撑架50，第一支撑件为柔性的密封元件40，在一些实施例中，由支撑架50和密封元件40共同夹持和保持雾化组件30。具体参见图5所示，刚性支撑架50上设置有沿长度方向延伸的第一壁510和第二壁520，且第一壁510和第二壁520分别靠近主壳体10沿厚度方向的两侧相对设置，并在第一壁510和第二壁520之间形成有雾化腔室530、和位于第一壁510和第二壁520两端并用于支撑吸液元件31的支撑槽540。根据图5中所示，该支撑槽540大体上呈U形形状。
在安装后，吸液元件31和加热元件32主要均容纳于雾化腔室530内进而能将生成的气溶胶释放至雾化腔室530，并由雾化腔室530通过密封元件40上的气管插接孔41输出至烟气输出管11。
加热元件32两端还通过细长的引脚或导线321与第二电触头21进而通过第二电触头21位加热元件32供电。
密封元件40进一步包覆在支撑架50的第一壁510和第二壁520外,并且装配后密封元件40从图5的上方夹持或压紧吸液元件31，从而使雾化组件30被稳定保持在密封元件40和支撑架50之间。
通常在可选的实施中，密封元件40是采用柔性材质制备的，通常例如硅胶、橡胶等。并在其上设置有气管插孔41，在装配中烟气输出管11的下端是插接在该气管插孔41内进而与雾化腔室530连通，从而将 雾化腔室530内的气溶胶输出至吸嘴口A处吸食。在使用中，密封元件40用于阻止储液腔12内的液体基质进而烟气输出管11和雾化腔室530，使得液体基质仅能通过被第一吸液元件31吸取的方式离开储液腔12。
进一步参见图5所示，密封元件40沿宽度方向的两侧设置有穿孔42，则在夹持或压紧吸液元件31后，能使吸液元件31至少部分通过该穿孔延伸至储液腔12内。
进一步对于电子烟雾化器100的气流设计，参见图4和图6所示；支撑架50上设置有主气室51、以及沿宽度方向位于主气室51两侧并与主气室51连通的缓冲气室52；缓冲气室52是直接与端盖20上的进气口22气流连通的，从而在抽吸中外部空气由进气口22进入至缓冲气室52，再由缓冲气室52进入至主气室51后，由出气孔511穿过雾化腔室530输出至烟气输出管11，形成完整的抽吸气流如图6中箭头R2所示。
进一步参见图6所示，密封元件40的结构包括有朝吸液元件31延伸出的保持部分43，并通过该保持部分43将吸液元件31夹持或压紧的方式保持在支撑架50上。
密封元件40靠近雾化腔室530的内壁上还设置有围绕气管插孔41的延伸凸沿44，该凸沿44与夹持部分43之间形成背离烟气输出管11的倒钩或者槽型空间45。当使用中雾化器100被平置或者是与图3中相反的方向倒置时，储液腔12内的液体基质沿图6箭头R3所示由保持部分43与吸液元件31之间的缝隙渗流至雾化腔室530内后，能被凸沿44阻挡，并保持于凸沿44与夹持部分43之间形成的倒钩或者槽型空间45内。从而阻止了液体基质直接流入至气管插孔41内导致在抽吸中被用户吸食的问题。
进一步参见图6所示，凸沿44与夹持部分43相对的外表面上呈台阶的形状设计，则当雾化器100从被平置或者倒置转为图3中抽吸或持握状态时，凸沿44台阶形的外表面能引导积存在倒钩或者槽型空间45内的液体基质滴落至雾化组件30上被重新汽化。或者在其他的变化实施中，凸沿44与夹持部分43相对的外表面是倾斜的设计，例如倾斜的平面、弧面等。
图7至图9示出了又一个实施例的雾化器100a的结构示意图，其构造包括：
主壳体10a，其上端设置有吸嘴口A，形状为中空且下端为敞口的中空筒状；
端盖20a，设置于主壳体10a下端的敞口上；
烟气输出管11a，沿主壳体10a的轴向延伸，用于将雾化器100a内生成的气溶胶输出至吸嘴口A；
储液腔12a，由主壳体10a与烟气输出管11a之间的空间界定形成，用于存储液体基质；
雾化组件30a，用于从储液腔12a通过毛细浸润吸取液体基质，并对吸取的液体基质加热汽化生成供吸食的气溶胶。具体，雾化组件30a包括沿主壳体10a的宽度方向延伸的吸液元件31a、以及至少部分围绕吸液元件31a并加热吸液元件31a的部分液体基质生成气溶胶的加热元件32a。吸液元件31a其两端是与储液腔12a流体连通的，储液腔12a内的液体基质沿图7中箭头R1所示由吸液元件31a两端被吸收后向内传递。同样，雾化器100a还包括有第二电触头21a用于为加热元件32a供电。
为了便于对储液腔12a的密封以及对雾化组件30a的保持，主壳体10a内还设有：
沿主壳体10a的纵向方向依次布置的第一支撑件和第二支撑件，其中，第一支撑件为刚性支架40a，第二支撑件为柔性支撑座50a；刚性支架40a靠近储液腔12a、柔性支撑座50a被保持在端盖20a上；装配后由刚性支架40a和柔性支撑座50a之间形成雾化腔室70a；雾化组件30位于刚性支架40a和柔性支撑座50a之间，并被刚性支架40a和柔性支撑座50a夹持或保持于雾化腔室70a内，进而在使用中将生成的气溶胶释放至雾化腔室70a。
同时刚性支架40a上设置有第一插接孔41a，供烟气输出管11a端部插接在第一插接孔41a内。刚性支架40a至少部分表面上包覆有密封元件60a，进而对刚性支架40a与主壳体10a的间隙进行密封，以阻止储液腔12a内的液体基质从它们的间隙渗出。
为了配合刚性支架40a的导液和装配，密封元件60a上设置有供液体基质流向刚性支架40a的第一导液孔62a、以及供烟气输出管11a贯穿后插入至第一插接孔41a的第二插接孔61a。同时，密封元件60a还对刚性支架40a与第一插接孔41a之间的间隙进行密封，阻止储液腔12a的液体基质从它们的缝隙伸入至烟气输出管11a内。
根据图7中箭头R1所示，刚性支架40a上还设置有第二导液孔42a，在使用中储液腔12a内的液体基质依次经第一导液孔62a、第二导液孔42a传递至雾化组件30a上被吸收和汽化。
具体在细节的构造上，柔性支撑座50a设置有朝刚性支架40a的凹腔51a，雾化组件30a被容纳和放置在该凹腔51a内。刚性支架40a则 配合柔性支撑座50a共同夹持雾化组件30a使其稳定保持在刚性支架40a和柔性支撑座50a之间。
柔性支撑座50a的一侧设置有进气通道52a，在使用中供外部空气依次经端盖20a上的进气孔和该进气通道52a进入至刚性支架40a和柔性支撑座50a之间的雾化腔室70a内。
进一步参见图9所示，刚性支架40a设置有朝雾化组件30a延伸出的保持部分46a，并通过该保持部分46a将雾化组件30a压紧或保持于刚性支架40a和柔性支撑座50a之间。
如图8中箭头R2所示，刚性支架40a还设置有位于中央并与第一插接孔41a相对的出气孔44a，雾化腔室70a内的气溶胶通过该出气孔44a输出至烟气输出通道11a。
刚性支架40a还设置有朝雾化腔室70a内延伸出的并围绕出气孔44a的第一凸沿442a，进而在第一凸沿442a与保持部分46a之间形成的倒钩或者槽型空间47a。用于当雾化器100a被平置或者是倒置时，阻止第二导液孔42a内的液体基质由保持部分46a与雾化组件30a之间的缝隙渗流至出气孔44a内。根据图10所示的优选实施，倒钩或者槽型空间47a的表面上形成有若干沿宽度方向延伸的沟槽471a，能吸附和保持流入倒钩或者槽型空间47a内的液体基质。
进一步参见图9和图10所示，刚性支架40a还设置有朝第一插接孔41a延伸出的第二凸沿441a，以及由第二凸沿441a的外壁界定并围绕第二凸沿441a的容纳或保持空间45a。当雾化器100a被用户手持倾斜抽吸时或者平置时，烟气输出管11a内壁上的气溶胶遇冷后的冷凝液等向下坠落时倾斜掉落至保持空间45a内而不直接竖直掉入至雾化腔室70a。同时，保持空间45a与刚性支架40a外壁上的若干毛细沟槽43a是气流连通的，进而保持空间45a内的冷凝液或液体等可以通过毛细吸附被传导或吸附至毛细沟槽43a，从而防止从端盖20a渗出。具体在图10中可以看出，保持空间45a是通过刚性支架40a两侧的窗口48a进而与毛细沟槽43a气流连通的。
进一步参见图10所示，刚性支架40a的保持部分46a位于第二导液孔42a与第一凸沿442a之间。在其他的变化实施中，保持部分46a也可以成U型的形状，进而可以与雾化组件30a的外形更加适配，有利于减少与雾化组件30a之间的间隙阻止降低液体基质的渗出。
同时在图9所示的优选实施中，柔性支撑座50a界定雾化腔室70a的内壁上，还形成有沿纵向方向延伸的第三毛细沟槽53a；该第三毛细沟槽53a的作用和目的基本是吸附或保持雾化腔室70a内生成并积存的 气溶胶的冷凝液，阻止其从进气通道52a流出。
进一步在以上优选的实施中，以上用于通过毛细作为吸附液体的毛细沟槽43a和/或沟槽471a和/或第三毛细沟槽53a宽度优选保持在毫米级。更加优选的是低于1mm。
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。
