本申请涉及电子雾化装置及其装配方法技术领域，特别是涉及一种密封件、密封组件、电子雾化装置及密封件的安装方法。
背景技术
现有技术中的电子雾化装置主要由雾化器和供电装置构成。雾化器将气雾生成基质进行加热雾化，形成可供吸食者食用的气雾，供电装置用于向雾化器提供能量。雾化器内一般还包括用于支撑雾化元件的雾化座，以使雾化元件、气流通道、储液腔等在雾化器内合理配置，保证工作顺利。由于涉及气体和液体的联通或导通，不同的组件之间经常需要安装密封件进行密封和隔离，一方面避免漏液、漏气等造成抽吸体验差，另一方面避免某些组件，如电源、PCB板、气动开关等受液体腐蚀，影响电子雾化装置的使用寿命。密封件若要起到良好的密封隔离作用，则需要与其他部件进行紧密配合，甚至需要被挤压，但是现有的电子雾化装置结构紧凑，需要隔离或密封的部件结构复杂，如何很好的安装密封件，使其能够发挥良好的密封隔离作用，是亟需解决的问题。

本申请提出一种密封件300、密封组件、电子雾化装置及密封件300的安装方法，其中，密封件300用于密封电子雾化装置中需要密封的部位。
在一个实施例中，电子雾化装置的整体结构如图1所示，电子雾化装置的纵向截面剖视图如图2所示。如图1所示，电子雾化装置包括盖体100和壳体200，电子雾化装置隐藏盖体100和壳体200后的结构如图4所示。
在一个实施例中，密封组件包括密封件300和结构件。在本实施例中，结构件可以为支架400。
具体地，在图2至图4中可以看到，壳体200内朝向远离盖体100的方向依次设置有储液腔210、导液件220、雾化芯230、雾化座240、密封件300、支架400、气动开关260、PCB板270和电源280。其中，储液腔210用于存储雾化液。导液件220中开设有导液孔221，用于将雾化液导出至雾化芯230。雾化芯230用于加热雾化液，使得雾化液雾化。雾化芯230靠近雾化座240一端设置有电触区，雾化座240的一端与电源280电性连接，另一端设置有电极250，电极250用于与雾化芯230的电触区电性连接，从而雾化座240能够为雾化芯230提供电力支持。如图3所示，支架400上设置有卡钩410，支架400通过卡钩410能够卡扣固定在壳体200的内壁上。一方面，支架400用于固定支撑雾化座240，使得雾化座240能够与雾化芯230电性连接，另一方面，支架400还用于支撑固定气动开关260和PCB板270。密封件300设置在支架400与雾化座240之间，用于防止雾化液渗漏到气动开关260和PCB板270。
如图2和图3所示，壳体200内还设置有气流通道，气动开关260设置在气流通道内，气流通道包括进气通道510和出气通道520，盖体100与壳体200的连接处设置有进气口511，盖体100远离壳体200的一端设置有出气口521，雾化芯230与雾化座240之间形成有雾化腔600，进气口511、雾化腔600和出气口521均与气流通道相连通。在一个具体的实施例中，电子雾化装置为雾化型电子烟，雾化芯230为多孔陶瓷发热体，雾化液为烟油。当用户抽吸时，气流通过进气口511进入进气通道510，触发气动开关260工作，雾化芯230发热将雾化液雾化，气流将雾化后的气体通过出气通道520和出气口521带出，供用户吸食。
在一个实施例中，密封件300和支架400连接前的结构如图5所示，支架400与密封件300相贴合的表面凹凸不平，支架400和密封件300相对应的位置均开设有电极穿入孔430，以供电极穿过。另外，支架400与密封件300贴合的表面两侧还分别设置有第一凸起440、第二凸起450，靠近第二凸起450的位置还设置有第三凸起460。第一凸起440和第二凸起450内均开设有磁铁槽451，第三凸起460内开设有咪头进气孔461，咪头进气孔461与电子雾化装置中的气流通道相连通，用于使得气流能够到达气动开关260。密封件300上与第一凸起440、第二凸起450、第三凸起460相对应的位置均开设有孔洞，其中，如图5和图6所示，磁铁槽451和密封件300上与第一凸起440、第二凸起450对应的孔洞用于放置磁吸件452，磁吸件452用于使得雾化座240与壳体200底部的电源280等组件相连接。
另外，如图5和图6所示，密封件300上在与第二凸起450、第三凸起460相对应的位置之间还设置有气流腔455，第二凸起450内的磁吸件452沿其轴向开设有气流孔453，气流孔453与电子雾化装置中的气流通道相连通，使得气流通道内的气流能够通过气流孔453流入到第二凸起450内的磁铁槽451。第二凸起450靠近第三凸起460的一端开设有缺口454，第二凸起450内的气流通过缺口454能够流入到密封件300上的气流腔455，再通过密封件300上的气流腔455能够流入第三凸起460内的咪头进气孔461内，使得气流能够到达气动开关260。支架400上第一凸起440、第二凸起450和第三凸起460均朝向密封件300的方向凸出于支架400表面，用于防止冷凝液流入内部的磁铁槽451或者咪头进气孔461。
另外，如图7所示，密封件300由硅胶等弹性材料制成，密封件300包括互相连接的主体部330和两个牵引部340，主体部330用于与支架400贴合，以实现密封功能，牵引部340用于对密封件300进行牵拉，使得主体部330能够与支架400贴合，如图5所示，主体部330包括平面部310和侧边部320，平面部310能够与支架400进行平面贴合，侧边部320能够包覆在支架400的外围侧边，与支架400进行曲面贴合。图7所示，支架400上设置有通孔420，牵引部340包括第一穿孔部341、挡部342和第二穿孔部343，挡部342位于第一穿孔 部341与第二穿孔部343之间，挡部342靠近主体部330的一端尺寸大于远离主体部330的一端尺寸，挡部342在通孔420径向上的最大尺寸大于通孔420的外径。在安装时，牵引部340能够通过通孔420对密封件300进行牵拉，挡部342通过通孔420时首先被弹性挤压，通过通孔420后弹性释放。密封件300与支架400连接后的结构如图6所示，密封件300的主体部330与支架400的一面贴合，挡部342与支架400的另一面贴合，从而，当牵引力撤去后，密封件300仍然能够与支架400紧密贴合。当密封件300与支架400连接后，根据具体情况，第二穿孔部343能够整体被移除或者部分移除，以避免牵引部340给后续工件的安装造成干扰。如图7所示，其中一个牵引部340的第二穿孔部343被部分移除，另一个牵引部340的第二穿孔部343被整体移除。在一个具体的实施例中，具体的移除方式可以是剪断等其他移除方式。
需要说明的是，在图7所示的实施例中，当密封件300与支架400紧密贴合后，其中一个牵引部340的第二穿孔部343被部分移除，另一个牵引部340的第二穿孔部343被整体移除。可以理解的是，在其他实施例中，牵引部340的整体长度较短，当密封件300与支架400紧密贴合后，第二穿孔部343的长度较短，不会影响到后续工件的安装，在此种情况下，密封件300及其第二穿孔部343也可以不被移除。
在图7和图8所示的实施例中，密封件300包括两个牵引部340，可以理解的是，本申请对牵引部340的数量不进行限定，在其他实施例中，可以理解的是，牵引部340的数量还可以为一个或者两个以上。另外，在图2至图4所示的实施例中，密封件300设置在雾化座240与支架400之间，可以理解的是，在其他实施例中，密封件300还可以与电子雾化装置中任意一个需要密封或者隔离的结构件相贴合以发挥密封或者隔离作用，避免漏液、漏气，或者避免某些组件，如电源280、PCB板270、气动开关260等受雾化液或者冷凝液等液体腐蚀。
另外，在一个实施例中，当密封件300与电子雾化装置中需要密封或者隔离的结构件相贴合后，为了方便第二穿孔部343的移除，密封件300的牵引部340上还设置有易断结构344。在一个具体的实施例中，如图10所示，密封件300包括第一牵引部350和第二牵引部360，第一牵引部350包括第一穿孔部351A、挡部352A和第二穿孔部353A，第二牵引部360包括第一穿孔部351B、挡部352B和第二穿孔部353B。其中，第一牵引部350的第二穿孔部353A包括保留部354和移除部355，保留部354和移除部355之间通过易断结构344连接，第二牵引部360的第二穿孔部353B与挡部352B之间通过易断结构344连接。易断结构344为哑铃状，易断结构344的中部尺寸小于两端尺寸，当牵引拉力达到一定临界力值时，易断结构344能够从中部被拉断。需要说明的是，牵拉密封件300的牵引部340，使得密封件300的主体部330紧密贴合支架400或其他结构件的牵拉力远小于使得易断结构344被拉断的临界力值，另外，第一牵引部350的保留部354长度较短，不会影响到后续部件的安装。设置保留部354的作用是提供操作空间，当密封件300与需要密封或者隔离的支架400或其他结构件相贴合后，操作人员可以手持保留部354和移除部355，分别对保留部354和移除部355施加方向相反的拉力，使得易断结构344的中间被拉断，移除部355脱离密封件300，并且在易断结构344被拉断的过程中，不会对密封件300的其他部分产生拉扯力，防止拉扯力过大影响密封件300其他部位的密封功能。
另外，可以理解的是，在其他实施例中，密封件300的牵引部340上还可以不设置挡部342。当密封件300与支架400或其他结构件紧密贴合在一起后，将雾化座240设置在密封件300的上方，使得密封件300被紧密挤压或者设置在雾化座240与支架400之间，然后，可以将牵引部340整体移除。在一个实施例中，如图11所示，牵引部340靠近主体部330的一端与主体部330之间设置有易断结构344，当密封件300被紧密挤压或者设置在雾化座240与支架400之间后，用力拉扯牵引部340，使得牵引部340整体被移除，当牵引部340被整体移除后，能够彻底避免牵引部340对安装后续工件安装时的干涉。
本申请还提出一种密封件300的安装方法，包括以下步骤：
S100、在牵引部340的牵拉辅助下，将密封件300的主体部330与结构件贴合；
S200、当主体部330与结构件贴合后，整体移除或者部分移除牵引部340。
本申请的密封件300、密封组件、电子雾化装置及密封件300的安装方法，通过在密封件300上设置辅助贴合密封的牵引部340，用于对密封件300进行牵拉，使得密封件300的主体部330能够与电子雾化装置中的结构件紧密贴合，发挥良好的密封作用，当密封件300的主体部330与电子雾化装置中的结构件贴合密封后，牵引部340还能够移除，不会妨碍电子雾化装置中后续工件的安装。
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申请专利范围的限制。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。
