具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的首选实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及/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所示，一实施方式的电子烟10包括雾化器100及电池装置300。电池装置300与雾化器100连接，电池装置300用于为雾化器100供电。
结合图2、图3及图4所示，雾化器100包括储液器120及发热组件130。储液器120具有用于收容雾化液的储液腔122，储液器120具有开口端121，开口端121上形成有与储液腔122连通的开口。储液器120可以为管状、立方体状、球状等能够收容雾化液的中空结构。发热组件130与储液器120连接，以用于吸取储液腔122内存储的雾化液，并将雾化液雾化。
发热组件130包括导液体131及发热件132。导液体131设置于开口端121，且导液体131具有面向储液腔122内的吸液面131a及位于储液腔122外的雾化面131b，导液体131能够将储液腔122内的雾化液传导至雾化面131b。发热件132形成在雾化面131b上，发热件132用于对传导至雾化面131b处的雾化液进行雾化，以得到雾化气而供吸食。
进一步地，吸液面131a上形成有凹槽131c，雾化液从凹槽131c的底壁到雾化面131b的最短传导距离小于雾化液从吸液面131a到雾化面131b的最短传导距离。在本实施例中，导液体131可以呈任意形状，吸液面131a、雾化面131b可以为平面或曲面，且吸液面131a与雾化面131b可以平行设置，或是呈一定夹角设置。当吸液面131a上未开设凹槽131c时，从吸液面131a到雾化面131b，雾化液必定具有一最短传导距离，而在吸液面131a上开设凹槽131c后，凹槽131c的底壁到雾化面131b之间就形成有另一最短传导距离，由于雾化液从凹槽131c的底壁到雾化面131b的最短传导距离又进一步小于雾化液从吸液面131a到雾化面131b的最短传导距离，因此雾化液能够快速地进入凹槽131c内，并沿凹槽131c的底壁到雾化面131b之间形成的最短传导路径传输，如此以来就缩短了雾化液的传导距离，减小了雾化液传输过程中受到的阻力，提高了导液体131的导液效率。同时，与吸液面131a上未开设凹槽131c的方案相比，本方案的导液体131与雾化液的接触面积更大，有助于雾化液的导出，而且也增大了储液腔122的体积，使储液腔122的储液量增加。
如图5所示，在其中一个实施例中，吸液面131a及雾化面131b分别位于导液体131的相对的两侧，导液体131还包括连接吸液面131a和雾化面131b的侧面131d。在本实施例中，导液体131呈柱状结构，且导液体131的相对的两端面分别为吸液面131a及雾化面131b，且吸液面131a与雾化面131b平行设置，此时，吸液面131a与雾化面131b之间的最短传输距离d1即为吸液面131a与雾化面131b之间的垂直距离。通过在吸液面131a与雾化面131b之间设置侧面，从而使得导液体131具有一定的厚度。
在一个实施例中，凹槽131c从吸液面131a向雾化面131b方向延伸。凹槽131c的底壁可以为曲面，或者为与雾化面131b平行或呈一定夹角设置的平面等任意形状。无论凹槽131c的底壁形状如何，凹槽131c都是沿与雾化面131b垂直的直线方向延伸而靠近雾化面131b，此时，雾化液沿凹槽131c的流通路径呈直线，如此设置可以避免凹槽131c呈弯曲状时，雾化液沿凹槽131c流动的路径过长而致使雾化液受到的阻力较大，以缩短雾化液沿凹槽131c的流动路径，减小雾化液受到的阻力，提高雾化液的传输效率。同时，凹槽131c的深度d2即为凹槽131c底壁上距离吸液面131a最远的位置到吸液面131a的距离，且凹槽131c底壁到雾化面131b的最短传导距离d3即为凹槽131c底壁上距离吸液面131a最远的位置到雾化面131b的距离，雾化液进入凹槽131c后会从凹槽131c底壁上距离吸液面131a最远的位置传导至雾化面131b。
进一步地，在一个实施例中，凹槽131c的底壁与雾化面131b之间的最短传导距离小于凹槽131c的深度，如此设置，可以进一步使得凹槽131c的底壁与雾化面131b之间的最短传导距离d3小于凹槽131c的深度d2，在导液体131厚度一定的情况下，可以通过增加凹槽131c的深度d2来减小凹槽131c的底壁与雾化面131b之间的最短传导距离d3，从而使得雾化液能够尽快流动至凹槽131c的底壁上距离雾化面131b最近的位置处，并在较小的阻力作用下经凹槽131c的底壁与雾化面131b之间的最短传导距离d3传导至雾化面131b，以提高导液体131的导液效率。
在一个实施例中，沿从吸液面131a向雾化面131b的方向，凹槽131c的横截面积逐渐缩小，从而使得凹槽131c在吸液面131a上具有较大的开口，以便于雾化液能够顺利的进入凹槽131c内，避免在凹槽131c的开口处形成薄膜而阻碍雾化液沿凹槽131c的流动。其中，凹槽131c可以呈台阶状或是锥状或是锥台状。
在一个实施例中，凹槽131c的底壁与雾化面131b平行，此时，凹槽131c的底壁与雾化面131b之间的最短传导距离即为凹槽131c的底壁与雾化面131b之间的距离，从凹槽131c底壁上的各个位置处，雾化液均能以最短传导距离传导至雾化面131b，从而进一步提高了导液体131的导液效率。
在其中一个实施例中，导液体131为多孔体。导液体131上开设有多个微孔，雾化液能够沿微孔流动而被传导至雾化面131b上。微孔的孔隙大小可以根据不同类型的雾化液来调整，例如雾化液粘稠度较大时，可以选择孔隙较大的导液体131，以使导液体131的导液效果适中。进一步地，在一个实施例中，导液体131为多孔陶瓷。
在一个实施例中，发热件132可以为发热涂层、发热线路、发热片或发热网。其中，发热涂层可以涂覆于雾化面131b上。发热线路可以镀在雾化面131b上。发热片、发热网可以通过其他辅助安装件而安装于雾化面131b上。发热件132为薄层结构，且能够与雾化面131b正对而使雾化面131b均匀受热，因此雾化作用的温度较为一致，不会因为局部温度低而致使雾化颗粒较大，有效保证了雾化颗粒均匀，提高了电子烟的口感。同时，发热件132与雾化液具有较大的接触面积，使雾化效率得以提高。
结合图2至图5所示，在一个实施例中，发热组件130还包括密封件133，密封件133至少部分位于导液体131与储液器120之间，以防止储液器120中的雾化液不经过导液体131而直接流出。在密封件133的密封作用下，储液器120内的雾化液只能沿吸液面131a与雾化面131b之间的传导路径导出。另外，导液体131具有一定的厚度才能满足密封件133的设置需求，在吸液面131a上开设凹槽131c，不仅可以使导液体131满足厚度需求，还能够满足 导液效率的需求。
进一步地，在一个实施例中，导液体131上靠近吸液面131a的一侧伸入储液器120的开口内，密封件133包括密封主体133a，密封主体133a套设于导液体131的侧面131d上，且与储液器120的内壁抵接，从而将导液体131与储液器120内壁之间间隙进行密封。
在一个实施例中，密封件133还包括第一卡合部133b及第二卡合部133c。第一卡合部133b形成于密封主体133a上靠近吸液面131a的一端，第二卡合部133c形成于密封主体133a上靠近雾化面131b的一端，第一卡合部133b和第二卡合部133c分别与导液体131的两端卡接，从而对导液体131与密封件133的相对安装进行限位，不仅便于导液体131与密封件133的安装，而且也能够防止导液体131与密封件133发生分离，保证密封主体133a的有效密封。进一步地，在一个实施例中，第一卡合部133b及第二卡合部133c均形成于密封主体133a的内壁上。导液体131的侧壁131d上形成有凸台部131e，第一卡合部133b与凸台部131e相抵接，第二卡合部133c与雾化面131b抵接，从而对导液体131进行位置限定。
在一个实施例中，密封件133还包括第三卡合部133d。第三卡合部133d形成于密封主体133a的外壁上靠近雾化面131b的一端，第三卡合部133d与储液器120的开口端121的端面抵接。第三卡合部133d的设置可以对发热组件130在储液器120的开口处的安装进行限位，避免密封件133及导液体131伸入储液器120的开口过深，以便于发热组件130与储液器120的组装。
在一个实施例中，密封件133还包括密封圈133e。密封圈133e形成于密封主体133a的外壁上靠近吸液面131a的一端。密封圈133e能够与储液器120的内壁紧紧抵接，以提高导液体131与储液器120之间的密封性。
在一个实施例中，密封件133为一体结构。密封主体133a、第一卡合部133b、第二卡合部133c、第三卡合部133d及密封圈133e一体成型。密封件133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133将导液体131包裹，可以减小雾化液不必要的挥发，同时具有隔热作用。硅 胶材质还可以避免导液体131与其他部件之间硬接触，从而可以避免导液体131出现损坏。
结合图2至4所示，在一个实施例中，导液体131上靠近吸液面131a的一侧伸入储液器120的开口内，储液器120的内壁上设有加强肋124，加强肋124能够与发热组件130上位于储液腔122内的一侧抵接。进一步地，加强肋124可以与导液体131的吸液面131a抵接，以对导液体131伸入储液器120的深度进行限定。或者，当密封主体133a套设于导液体131的侧面131d上，且与储液器120的内壁抵接时，加强肋124还可以与密封件133的靠近吸液面131a的一端抵接，以对密封件133伸入储液器120的深度进行限定。或者，加强肋124还能够同时与导液体131的吸液面131a及密封件133的端面抵接，以对发热组件130伸入储液器120的深度进行限定。在一个实施例中，在一个实施例中，加强肋124为多个，多个加强肋124沿储液器120的周壁面均匀分布，以对发热组件130位于储液腔122内的一端施加较为均匀的作用力。
在一个实施例中，雾化器100还包括外壳110。外壳110上开设有进气口111及出气口112，发热组件130及储液器120均容置于外壳110内，发热组件130靠近进气口111设置，外壳110与储液器120之间具有连通进气口111与出气口112的气流通道。气流能够从进气口111进入，发热件132雾化得到的雾化气会随气流一起经气流通道后从出气口112导出，以供吸食。
进一步地，在一个实施例中，储液器120呈长管状结构，储液器120的外壁略小于外壳110的内壁，以便于储液器120能够容置于外壳110内。储液器120的外壁与外壳110的内壁之间的缝隙较小，不利于气流及雾化气导出。通过在储液器120的外壁上开设纵向槽125，从而在储液器120与外壳110之间形成气流通道，以便于气流能够沿纵向槽125导出至出气口112。或者，还可以将纵向槽125开设于外壳110的内壁上。或者，还可以同时在储液器120的外壁上及外壳110的内壁上开设纵向槽125。进一步地，储液器120的外壁上开设有两个纵向槽125，两个纵向槽125相对设置，从而在储液 器120与外壳110之间对称的形成两条气流通道，以增加气体及雾化气的流量，并提高吸食口感。
在一个实施例中，部分密封件133位于导液体131与储液器120之间，以对储液器120及导液体131之间进行密封，部分密封件133与外壳110的内壁抵接，以使得从进气口111进入的气流能够更多的到达发热件132处，且与雾化气充分混合，以将更多的雾化气携带至出气口112。此时，密封件133上开设有第一缺口133f，储液器120的开口端121开设有第二缺口126，第一缺口133f、第二缺口126连通进气口111及纵向槽125。携带有雾化气的气流经第一缺口133f、第二缺口126而进入纵向槽125内，并经出气口112导出。进一步地，第一缺口133f及第二缺口126均为两个，以使两个纵向槽125均能够与进气口111相连通。
结合图1及图6所示，在一个实施例中，电池装置300包括壳体310、电池320及弹针330。电池320收容于壳体310内，弹针330安装于壳体310上，且与电池320及发热件132分别电连接。如图2及图4所示，在一个实施例中，雾化器100还包括电极140，电极140安装于外壳110上，且与发热件132电连接。弹针330与电极140电连接，以通过电极140对发热件132供电。在一个实施例中，壳体310与外壳110相卡接，以实现电池装置300与雾化器100的快速拆装。进一步地，如图4及图6所示，壳体310的一端收容与外壳110内，外壳110的内壁上设置有突起部113，壳体310的外壁上开设有限位槽311，突起部113能够卡设于限位槽311内，从而实现外壳110与壳体310的快速连接。或者，还可以将外壳110的一端收容于壳体310内。进一步地，外壳上开设有进气缺口114，壳体310的与外壳110之间具有一定间隙，从而形成进气通道，进气通道与外壳110上的进气口111相连接，气流经壳体310与外壳100之间的进气通道后，再经进气口111进入外壳110内部。
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。
