同时参阅图1和图2，本申请一实施例提供的雾化器10可以用于对以气溶胶生成基质为代表的液体进行雾化。雾化器10包括壳体100、雾化组件200、隔液件300、通断阀400和密封件500。
同时参阅图1、图2和图7，在一些实施例中，壳体100包括外壳部110、插置部120和加强肋130。外壳部110围设成一个收容腔150，插置部120竖直设置在该收容腔150中，插置部120的上端与外壳部110连接，雾化组件200的容置在该收容腔150中，雾化组件200、外壳部110和插置部120将收 容腔150的一部分围成储液腔151，储液腔151用于存储液体。该插置部120中开设有吸气通道140，吸气通道140沿插置部120的轴向延伸，吸气通道140能够连通外界，在抽吸过程中，液体被雾化组件200雾化形成的烟雾能够经该吸气通道140被用户抽吸。
加强肋130与插置部120的上端连接，加强肋130的数量可以为两个，两个加强肋130关于插置部120对称设置，加强肋130还与外壳部110连接，即加强肋130连接在插置部120与外壳部110之间。由于插置部120具有一定的长度并悬空设置在壳体100的收容腔150中，通过设置加强肋130，可以提高插置部120安装的稳定性。
同时参阅图2至图6，在一些实施例中，雾化组件200包括雾化芯210、顶盖220和底座230，顶盖220设置有连通储液腔151的容置腔223，雾化芯210位于该容置腔223中，底座230包括相互连接的第一安装部231和第二安装部232，第一安装部231位于顶盖220的容置腔223中，第二安装部232位于顶盖220的容置腔223之外，第二安装部232上设置有台阶面232a，该台阶面232a位于第二安装部232的边缘并沿第二安装部232的周向延伸，顶盖220与台阶面232a相抵接，台阶面232a为顶盖220的安装提供很好的定位，顶盖220上设置有卡抓221，第二安装部232上开设有卡孔，通过卡抓221与卡孔的配合，可以实现顶盖220与底座230之间可拆卸的卡扣连接关系。
参阅图2，底座230的第二安装部232上开设有气流通道160，该气流通道160与吸气通道140连通，壳体100的外壳部110上开设有进气口111，该进气口111连通外界和气流通道160，即气流通道160通过进气口111与外界连通。在抽吸过程中，外界气体经气流通道160和吸气通道140进入用户口腔。
雾化芯210用于吸收储液腔151的液体并将液体雾化形成供用户抽吸的烟雾，雾化芯210可以采用多孔陶瓷材料制成，多孔陶瓷材料具有很好的毛细作用，确保雾化芯210对液体具有良好的吸收功能。当然，液体分子能通 过多孔陶瓷材料做成雾化芯210，由于气体分子的直径和粘度比液体分子小，气体分子同样能通过该雾化芯210，故多孔陶瓷材料制成的雾化芯210也具有良好的透气性能。雾化芯210还可为其它具有较好储液性能和透气性能的多孔材料。
同时参阅图2和图6，雾化芯210包括相互连接的本体部211和凸缘部212，本体部211大致呈圆柱状或棱柱状等。凸缘部212环绕本体部211设置，凸缘部212可以沿与本体部211轴向呈设定夹角的方向相对本体部211表面延伸设定长度，例如，凸缘部212沿与本体部211轴向垂直的方向延伸。在其它实施例中，雾化芯210可以只设置呈柱状的本体部211，该本体部211上并未设置凸缘部212。
在一些实施例中，雾化芯210的本体部211的内部开设有导液通道213，导液通道213的两端均与储液腔151连通，导液通道213可以横向设置，即导液通道213与竖直设置的吸气通道140垂直。通过设置导液通道213，可以使储液腔151中的液体直接通过导液通道213而进入雾化芯210的内部，提高雾化芯210的导油效率，同时也使得液体在雾化芯210上的分布更加均匀，避免雾化芯210因局部供液不足形成干烧，进而防止干烧产生的焦味。在其它实施例中，也可以不设置导液通道213，即雾化芯210通过毛细作用直接从储液腔151中吸收液体以雾化。
同时参阅图2、图5和图6，通断阀400包括相互连接的拉扯部420和封堵部410，拉扯部420呈杆状，拉扯部420的一部分能够穿过底座230并外露于底座230，封堵部410呈板状，封堵部410可以与顶盖220和底座230滑动连接，拉扯部420用于带动封堵部410做直线滑动。具体而言，通断阀400具有第一工位11(参阅图5)和第二工位12(参阅图2)，在雾化器10使用之前，通断阀400处于第一工位11，通断阀400的封堵部410能够对导液通道213进行封堵，避免储液腔151中的液体进入导液通道213并泄露出雾化芯210，从而有效防止整个雾化器10在存储或运输过程中产生的液体泄露。在雾化器10使用时，可以对拉扯部420施加拉力，将通断阀400从第一 工位11运动至第二工位12，使封堵部410打开导液通道213，此时，储液腔151中的液体能快速通过导液通道213进入雾化芯210以便雾化。该雾化器10可以为一次性使用的雾化器10，当通断阀400位于第二工位12时，拉扯部420可以被拉断而与封堵部410相脱离，断裂后的拉扯部420可以被丢弃。在其它实施例中，通断阀400可以相对雾化芯210转动，即通断阀400与整个雾化组件200转动连接，只要转动的通断阀400能打开或封堵导液通道213即可。
在一些实施例中，在材料上，隔液件300可以为隔液棉，隔液棉可以为成分为植物纤维的无纺布、有机棉和生态棉等。隔液棉具有良好的透气性，使得气体能从隔液棉的一侧穿过该隔液棉而进入隔液棉的另一侧；同时，隔液棉具有良好的吸液性，即隔液棉对液体具有较强的吸附作用，使得液体无法从隔液棉的一侧流过该隔液棉而流入隔液棉的另一侧，从而确保隔液棉对液体流动的阻碍功能。在形状上，隔液件300可以为板状结构。
同时参阅图2至图6，凸缘部212上开设有贯穿孔214，底座230、顶盖220和雾化芯210三者围设成一个雾化腔235，贯穿孔214形成雾化腔235的一部分，雾化芯210将液体雾化的烟雾能够经该雾化腔235从吸气通道140流出。该雾化腔235同时连通吸气通道140和气流通道160。隔液件300上开设有安装孔310，雾化芯210的本体部211穿设在该安装孔310中，以便对隔液件300的安装进行定位。凸缘部212与隔液件300的内侧相抵压，底座230的第一安装部231与隔液件300的外侧相抵压，即隔液件300被夹置在凸缘部212与第一安装部231之间，此时，隔液件300能封堵贯穿孔214远离雾化腔235的端口。
第一安装部231上设有第一通孔233和第二通孔234，第一通孔233能够连通储液腔151，第一通孔233与雾化腔235两者共同形成一个换气通道201。雾化芯210本体部211的端部可以插置在该第二通孔234中，第二通孔234为雾化芯210的安装起到很好的定位作用，同时，储液腔151中的液体能够从第二通孔234进入导液通道213。当通断阀400处于第一工位11时， 通断阀400的封堵部410封堵第二通孔234，以避免储液腔151中的液体经第二通孔234进入导液通道213。当通断阀400处于第二工位12时，通断阀400的封堵部410打开第二通孔234，使储液腔151中的液体顺利经过第二通孔234进入导液通道213，图2中实线箭头为液体的流向。
由于隔液件300封堵了贯穿孔214远离雾化腔235的端口，使得储液腔151中的液体无法通过第二通孔234而流经隔液件300并进入贯穿孔214中，防止液体堵塞整个换气通道201，进一步防止液体进入雾化腔235、气流通道160和吸气通道140，确保从气流通道160中流入的气体快速进入储液腔151中。同时，凸缘部212具有与隔液件300较大的接触面积，隔液件300上吸附的液体能够通过凸缘部212吸收以便雾化，使得隔液件300的吸液容量被及时释放，确保隔液件300能长期利用并发挥对液体流动的阻碍功能。
在抽吸过程中，随着液体被持续雾化而消耗，使得储液腔151中的液体减少，储液腔151的空间得到释放。此时，外界气体可以依次经气流通道160、雾化腔235、贯穿孔214、隔液件300和第一通孔233而进入储液腔151中，图2中虚线箭头为气体的流向，气体将填充储液腔151不存在液体的空间中，该填充气体能有效增大储液腔151中的气体压力，该气体压力作用在储液腔151中剩余的液体上，确保储液腔151顺利对雾化芯210供液，避免雾化芯210因储液腔151内的真空或负压而导致液体供应不足的缺陷，防止液体供应不足而产生影响抽吸体验的焦味。
因此，通过设置换气通道201，并充分利用隔液件300良好的透气性能，可以确保外界空气经气流通道160、换气通道201和隔液件300而进入储液腔151中，避免储液腔151中出现真空而产生负压，确保储液腔151中的液体能顺利流入至雾化芯210，防止雾化芯210因液体供应不足而产生烧焦现象。同时充分发挥隔液件300良好的吸液功能，防止储液腔151中的液体填充整个换气通道201而形成对气体流动的阻碍作用，确保从气流通道160中流入的气体快速进入储液腔151中。隔液件300具有较好的储液和导液功能，当雾化芯210上供液不足或隔液件300吸满液体，由于与雾化芯10邻近，隔 液件300吸收和储存的液体传导到雾化芯210上，提升导液效率，缓解供液不足可能产生的烧焦。
在一些实施例中，顶盖220上开设有固定孔222，该固定孔222连通雾化腔235，插置部120的端部与固定孔222配合，使得固定孔222连通吸气通道140。密封件500可以为密封圈，密封圈嵌设在底座230的第二安装部232上，当第二安装部232的一部分与收容腔150配合时，密封圈抵压在第二安装部232与外壳部110的内壁面之间，密封件500可以起到密封作用，防止储液腔151中的液体从第二安装部232与外壳部110之间的缝隙进行泄露。
用户抽吸时，先往下牵引拉扯部420，整个通断阀400从第一工位11运动至第二工位12，使封堵部410打开第二通孔234和导液通道213，储液腔151中的液体经导液通道213快速进入雾化芯210以便雾化，吸气通道140的末端在插置部120上形成吸嘴口141，用户可以在吸嘴口141处抽吸烟雾。
本申请还提供一种电子雾化装置，该电子雾化装置包电源组件和上述的雾化器10，电源组件与雾化器10连接，电源组件用于对雾化芯210加热以对液体进行雾化。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
