结合图1及图2所示，一实施例的电子烟10包括雾化器20及电池杆40，雾化器20和电池杆40可以通过可拆卸的方式连接，如螺纹连接。雾化器20包括储液件21及雾化组件22，储液件21具有用于收容雾化液的储液腔211，以用于收容雾化液，雾化组件22与储液件21连接，以吸取储液件21收容的雾化液，并将雾化液雾化。电池杆40与雾化组件22电连接，以为雾化组件22供电，以使雾化组件22将雾化液雾化。
如图3及图4所示，雾化器20还包括端盖23，端盖23与储液件21连接，以形成收容空间，雾化组件22容置于收容空间内。端盖23上开设有进气孔231，储液件21内部形成有吸气通道25，雾化组件22内形成有与吸气通道25连通的第一气流通道26，由进气孔231进入的气流能够流经第一气流通道26，并携带雾化组件22雾化得到的雾化气进入吸气通道25，并在吸气通道25的远离第一气流通道26的一端被吸食。
雾化器20还包括挡片24，挡片24容置于收容空间内，且位于进气孔231处。挡片24与端盖23之间形成有连通进气孔231与第一气流通道26的第二气流通道271。通过在进气孔231处设置挡片24，从进气孔231进入的气流能够经挡片24与端盖23之间的第二气流通道271进入第一气流通道26，在不影响气流进入的情况下，挡片24能够对进气孔231起到遮挡作用，以避免从雾化组件22泄露的雾化液或是第一气流通道26冷凝回流的雾化液沿雾化器20的轴向下落经进气孔231流出雾化器20，进而避免雾化液流出对雾化器20与电池杆40的连接处造成污染。
在一些实施例中，挡片24在垂直于雾化器20轴向的平面上的投影覆盖进气孔231。其中，雾化器20呈柱状结构，进气孔231位于雾化器20的一端，雾化器20的轴向即为进气孔231的进气方向。具体地，挡片24与垂直 于雾化器20轴向的平面平行设置，挡片24在垂直于雾化器20轴向的平面上的投影完全覆盖进气孔231，即进气孔231完全落入挡片24在垂直于雾化器20轴向的平面上的投影内，此时，挡片24能够对进气孔231完全遮挡，以避免雾化液落入进气孔231内。也就是说，挡片24的尺寸要大于进气孔231的尺寸，挡片24才能够完全覆盖进气孔231，以对进气孔231起到较好的遮挡作用。在其他实施例中，挡片24的尺寸还可以等于进气孔231的尺寸，此时，挡片24与进气孔231正对设置，且恰好能够完全覆盖进气孔231。此外，在其他实施例中，挡片24还可以与垂直于雾化器20轴向的平面呈一定夹角设置。挡片24在垂直于雾化器20轴向的平面上的投影还可以仅覆盖部分进气孔231，此时，挡片24仍然能够对进气孔231起到遮挡作用，以使落入进气孔231内的雾化液减少。
挡片24与端盖23之间形成与进气孔231连通的第二气流通道271，挡片24上背离端盖23的一侧与雾化组件22之间形成与第一气流通道26连通的第三气流通道272，第二气流通道271通过第三气流通道272与第一气流通道26连通，从而连通进气孔231与第一气流通道26。具体地，第二气流通道271与第三气流通道272在挡片24的周缘处连通，以共同形成连通进气孔231与第一气流通道26的进气通道27。挡片24的设置能够改变进气孔231与第一气流通道26之间的气流路径，以对进气孔231进行有效遮挡，从雾化组件22泄露的雾化液或是第一气流通道26冷凝回流的雾化液沿雾化器20的轴向下落后，都无法落入进气孔231内而流出雾化器20，避免了对雾化器20与电池杆40的连接处造成污染。
结合图2至图5所示，在一些实施例中，挡片24包括主体部241及与主体部241连接的导引部242。主体部241呈平板状，且垂直于雾化器20的轴向设置。导引部242位于主体部241的边缘处，且向端盖23一侧延伸，以使挡片24呈弯折状。具体地，主体部241与进气孔231正对设置，从雾化组件22泄露的雾化液，或是从第一气流通道26冷凝回流的雾化液能够落在主体部241上，在流动至主体部241的边缘处之后，雾化液能够在导引部242的 作用下落至端盖23上。在主体部241与导引部242的配合作用下，泄露或回流的雾化液能够被引导至端盖上，避免雾化液四溅而落入进气孔231内。
在一些实施例中，端盖23包括底壁232及设于底壁232上的凸起部233，进气孔231贯穿底壁232及凸起部233。挡片24能够覆盖凸起部233，以使得雾化液能够落至底壁232上，由于底壁232上设置有凸起部233，凸起部233能够对雾化液形成阻挡，以避免雾化液流入进气孔231内。另外，凸起部233与主体部241之间、凸起部233与导引部242之间均存在间隙，从而使得从进气孔231进入的气流能够顺次经过凸起部233与主体部241之间的间隙及凸起部233与导引部242之间的间隙，从而形成第二气流通道271。进一步地，导引部242突出主体部241的高度大于或等于凸起部233与主体部241之间的间隙，使得挡片24与凸起部233之间形成的第二气流通道271呈弯折状，从而使导引部242能够对凸起部233与主体部241之间的间隙进行遮挡，以避免雾化液飞溅入进气孔231内。端盖23还包括设于凸起部233上的支撑柱234，支撑柱234为多个，多个支撑柱234间隔设置。支撑柱234能够与主体部241抵接，以对主体部241起到支撑作用，同时，在主体部241与凸起部233之间，任意相邻两个支撑柱234之间均形成与进气孔231连通的间隙，以便从进气孔231进入的气流通过。
在一些实施例中，端盖23还包括围设于底壁232周缘的侧壁235，侧壁235与凸起部233均位于底壁232的同侧，且侧壁235、底壁232及凸起部233共同围成用于收容雾化液的收容槽236。从雾化组件22泄露的雾化液，或是从第一气流通道26冷凝回流的雾化液能够直接落入收容槽236内，或者先落在挡片24上之后再进一步落入收容槽236内，并在收容槽236内得以收集。
结合图2及图3所示，在一些实施例中，储液件21包括外管212及内管213，内管213设置于外管212内部，在储液件21的一端，外管212与内管213连接，以使外管212与内管213之间形成储液腔211，雾化液能够存储于储液腔211内。具体地，外管212与内管213一体成型，不仅在内管213与 外管212之间形成了储液腔211，同时也在内管213内部形成了吸气通道25，而无需额外设置供气流流经的通道。进一步地，外管212的长度大于内管213，雾化组件22能够容置于外管212内，端盖23与外管212可拆卸连接，以将雾化组件22限位于外管212内。端盖23的侧壁235与外管212相卡接。在其他实施例中，端盖23还可以采用螺纹连接的方式与外管212实现可拆卸连接。或者，端盖23还可以与外管212一体成型，此时，端盖23的侧壁235即为外管212的一部分，以与凸起部233之间共同形成收容雾化液的收容槽236。
在一些实施例中，雾化组件22包括导液体221及密封件222，导液体221用于从储液腔211吸入雾化液，至少部分密封件222位于导液体221与储液件21之间，以防止储液腔211中的雾化液不经过导液体221而直接流出。雾化组件22收容于外管212与端盖23所围成的收容空间内，且位于内管213的末端。第一气流通道26贯穿地形成于导液体221内部，且与进气孔231正对设置，且第一气流通道26与形成于内管213内部的吸气通道25连通，气流能够顺次经过第一气流通道26及吸气通道25，进而在吸气通道25的远离第一气流通道26的一端导出雾化器20。
结合图3、图4、图6及图7所示，密封件222包括密封主体222a，密封主体222a套设于导液体221上，且密封导液体221与外管212之间的间隙，以避免储液腔211内的雾化液沿导液体221与外管212之间的间隙流出。密封件222还包括第一抵持部222b，第一抵持部222b与密封主体222a平滑连接，且第一抵持部222b套设于导液体221上。第一抵持部222b的远离密封主体222a的一端收容于端盖23的侧壁235所围成的空间内，沿第一抵持部222b上与导液体221接触的侧面渗漏的雾化液能够被引导至收容槽236内，避免雾化液外漏。
在一些实施例中，主体部241与导液体221之间存在间隙，以形成部分第三气流通道272。第一抵持部222b套设于导液体221上，并向端盖23侧延伸而超出导液体221的底面，第一抵持部222b与挡片24连接，并使挡片 24与导液体221的底面之间存在以便气流流过的间隙，从而形成部分第三气流通道272。此外，部分第一抵持部222b在导液体221的底面处向导液体221一侧弯折，以对导液体221形成支撑作用，并进一步向端盖23侧延伸，以与主体部241周缘的部分位置连接，而导引部242设置于主体部241周缘未与第一抵持部222b连接的位置，部分第一抵持部222b向端盖23延伸以与导引部242平齐，并与导引部242连接而共同围成部分第三气流通道272，从而使得第一抵持部222b与导引部242共同围成的空间与导液体221的底面与主体部241之间的间隙共同形成第三气流通道272。导引部242与端盖23的底壁232之间存在间隙，从而使得第二气流通道271与第三气流通道272连通。
如此一来，从进气孔231进入的气流需要先经过挡片24与端盖23之间形成的折弯状第二气流通道271，之后再经过挡片24与雾化组件22之间形成的折弯状第三气流通道272，之后才能被导引至第一气流通道26，如此设置，不仅较大程度的增加了泄露或冷凝回流的液化液进入进气孔231的难度，而且也延长了气流从进气孔231到达第一气流通道26的路径长度，可以使得从进气孔231进入的低温气流在经过逐渐预热后到达第一气流通道26内，并携带雾化组件22雾化得到的雾化气进入吸气通道25。同时，也避免了从进气孔231进入的低温气流快速接触雾化组件22后，导致雾化组件22表面的温度较低而致使雾化效率及雾化效果降低。
进一步地，密封件222还包括与密封主体222a连接的第二抵持部222c，第二抵持部222c夹持于储液件21与端盖23的侧壁235之间，且第二抵持部222c与第一抵持部222b相配合而夹紧端盖23的侧壁235。密封件222为一体成型结构。密封件222可以是硅胶材质，也可以是其他具有密封、隔热功能的材质。密封件222包裹导液体221可以减小雾化液不必要的挥发，同时具有隔热作用，避免雾化器20的外部过热，节省能量。密封件222可以具有弹性，以避免导液体221与其他部件之间硬接触而致使导液体221出现损坏。另外，密封件222与挡片24一体成型，能够有效避免挡片24的额外组装操作，降低雾化器20的组装复杂性。
结合图2及图3所示，在一实施例中，雾化组件22还包括发热结构223，发热结构223位于导液体221的围成第一气流通道26的内壁上。导液体221为多孔结构，储液腔211内的雾化液能够进入导液体221内，并经过导液体221内的网孔流出至形成第一气流通道26的内壁上，并被发热结构223雾化。另外，导液体221具体为陶瓷芯。发热结构223还可以为发热丝或发热电路层或发热膜。在发热结构223的加热作用下，导液体221也能够进行热传导并将位于其内部的雾化液雾化。雾化器20还包括电极31及导引线32，电极31嵌设于端盖23上，电池杆40与电极31电连接。导引线32与电极31电连接，并贯穿端盖23，以与发热结构223电连接，以为发热结构223供电。
雾化组件22还包括导液片224及导液棉225，导液片224及导液棉225均设于内管213与外管212之间。导液片224上开设有限流孔224a，导液片224覆盖导液棉225，而导液棉225又与导液体221连接。储液腔211内的雾化液能够通过限流孔224a流出至导液棉225内，导液棉225又能够进一步将吸取的雾化液传导至导液体221内，在发热结构223的加热作用下，导液体221内的雾化液被雾化。导液片224上限流孔224a的设置，可以对雾化液的导出速度进行限制，避免雾化液导出速度过快而无法被充分雾化。举例说明，导液体221可为陶瓷芯，在发热结构223的加热作用下，导液体221的温度也能够升高，从而对从导液棉225流出的雾化液进行预热，甚至能够对雾化液进行雾化，从而提高雾化液的雾化效率，并使雾化液得到充分雾化，提高雾化效果。另外，由于导液棉225的热传导效率低于导液体221，因此，导液棉225能够起到较好的隔热作用，避免导液体221的热量被传导至导液片224及导液腔内的雾化液，减少了热量的额外损失，提高了热量的利用率。
再次参阅图1所示，雾化器20还包括第一套体28及第二套体29，储液件21的外管212上设有凸缘214，第一套体28套设于外管212的远离端盖23的一端，第二套体29套设于外管212的远离第一套体28的一端，且第一套体28及第二套体29分别与凸缘214的相对两侧抵接，并形成雾化器20平滑过渡的表面。第二套体29能够将端盖23上的进气孔231覆盖，以在雾化 器20与电池杆40分开后，防止气体进入雾化器20内部而造成雾化液的挥发。
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发明的几种实施方式，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，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
