Description

电子烟雾化装置及电子烟
本申请要求于2021年9月24日提交中国专利局、申请号为202122325826.3、申请名称为“电子烟雾化装置及电子烟”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子烟技术领域，更具体地，本申请涉及一种电子烟雾化装置及电子烟。
背景技术
近年来，随着民众生活水平的逐步提高，人们对身体健康的关注度普遍上升，越来越多的人开始意识到烟草对身体的危害。于是，电子烟的使用者日益剧增，电子烟是一种仿卷烟的电子产品，其有着与卷烟类似的外观、烟雾、味道和感觉。电子烟产品采用对烟油进行雾化的方式，为用户提供可抽吸的烟雾。电子烟与真烟产品相比，优点在于其对用户的健康危害大幅度下降；并且电子烟大多使用操作方便、外观精美且便于携带。
电子烟一般包括电源组件和雾化器，电源组件向雾化器供电后雾化器将烟液进行加热雾化形成烟雾被用户吸食。
在现有的电子烟中，雾化芯上供气流流通的通孔设置于雾化芯的中心位置，当外界空气进入到电子烟中并与雾化芯产生的烟雾混合后，便立即直接从雾化芯中心位置的通孔上升进入到电子烟的出气通道中，这样容易造成外界空气与烟雾混合不均匀、抽吸口感较差的问题。当雾化芯上的通孔偏心设置时，与雾化芯通孔相连通的出气口也需要相应地进行偏心设置，但偏心设置的出气口不仅会造成用户抽吸时的舒适度降低，并且还会影响到电子烟外观的美观度。

在本申请实施例提供的电子烟雾化装置中，首先，烟油通过雾化芯3的多孔体31从其吸液面渗透到雾化面，并在雾化面上由发热体组件进行加热产生烟雾。其中，多孔体31的第一中心轴与通孔311的第二中心轴不重合，第二中心轴相对于第一中心轴有一定预定距离的偏移量，亦即，通孔311在多孔体31上为偏心设置。在该电子烟雾化装置中，偏心设置的通孔311为一个偏孔，当外界空气从下盖2进入到雾化腔20，并与雾化面上产生的烟雾混合后，气流会绕至偏心设置的通孔311处再向上进入到出气通道11中，因此，偏心设置的通孔311可以帮助改善电子烟中的气流的流动气路，提高外界进入电子烟的空气与电子烟内产生的烟雾之间混合的均匀度。
其次，当偏置的通孔311通过出气通道11与出气口101连通时，如果出气通道11设置成侧壁为竖直的形式，那么出气口101需要跟随通孔311做偏置处理，即需要将出气口101的中心轴也相对于第一中心轴偏移一定距离，那么出气口101在壳体1的第一端面上即为偏心设置；如果出气口101在第一端面上偏心设置，这样用户在出气口101处进行抽吸的舒适度会大大降低，并且，偏心设置的出气口101会使电子烟的外观美观度大打折扣；此外，如果出气口101在壳体1的第一端面上为偏心设置，那么会造成第一端面的一侧的厚度较薄，这样会影响到厚度较薄这一侧的强度。因此，在本申请实施例提供的电子烟雾化装置中，将出气口101在壳体1的第一端面上进行居中设置，即出气口101的中心轴与第一中心轴相重合，即在利用具有偏心通孔的雾化芯3的同时，确保出气口101的居中设置。
再次，在本申请实施例中的电子烟雾化装置中，只采用壳体1与下盖2配合的形式对雾化芯3和雾化芯密封件4等结构进行限位，取消了传统结构中的上支架、上支架密封圈及下支架，大大简化了电子烟雾化装置内部的结构，从而节约了零件制造成本和装配成本、提高了生产效率。并且，该电子烟雾化装置的结构为储液腔102、雾化腔20留出了更多的空间，这样的电子烟雾化装置中，用于存储烟油的储液腔102的体积及烟雾形成的空间——雾化腔20的体积相对于现有技术能够做到更大。此外，现有技术中，在雾化芯组件与壳体内壁之间设置有上支架，而在本申请实施例提供的电子烟雾化装置中，雾化芯组件直接紧贴壳体1的内壁，因此可以将雾化芯组件中的雾化芯3的体积做得更大，烟油从吸液面到雾化面的面积更大，在用户抽吸时，渗油量增大，从而烟雾量增大，抽吸的口感更好。
在一个实施例中，沿着所述第二中心轴相对于所述第一中心轴偏移的方向，所述第一中心轴所在的剖面与所述出气通道11的内壁面具有第一相交线111和第二相交线112，所述第 一相交线111和所述第二相交线112均相对于所述第一中心轴倾斜设置。
在该具体的例子中，为了将居中设置的出气口101与偏心设置的通孔311进行连接，因此将出气通道11进行倾斜设置，即出气通道11的内壁面并不是竖直设置的，而是呈现出一定角度的倾斜，出气通道11的中心轴相对于第一中心轴具有一定角度的倾斜，以确保将居中设置的出气口101与偏心设置的通孔311相连通。
参照图1所示，在一个实施例中，沿着所述第二中心轴相对于所述第一中心轴偏移的方向，所述第一相交线111相较所述第二相交线112更加靠近所述第一中心轴设置；所述第一相交线111与所述第一中心轴具有第一夹角，所述第二相交线112与所述第一中心轴具有第二夹角，所述第一夹角大于所述第二夹角。
由于通孔311的第二中心轴与多孔体31的第一中心轴不重合，二者具有一定距离，又由于出气口101在第一端面上为居中设置，出气口101的中心轴与第一中心轴重合，在第一中心轴所在的剖面处，第一相交线111及第二相交线112与第一中心轴的距离不同，并且与第一中心轴的夹角也不相同。
参照图1所示，在一个实施例中，所述第一相交线111与所述第二相交线112从所述出气通道11的第一端至所述出气通道11的第二端呈逐渐靠近设置。
在该具体的例子中，出气通道11呈现出上端口径较大、下端口径较小的形状；即出气口101处的口径较大，远离出气口101的另一端的口径较小。这样有利于气流的爬升，避免用户抽吸困难，并且用户在出气口101处抽吸时进入口腔的气流量较大、抽吸口感较好。
参照图5所示，在一个实施例中，所述电子烟雾化装置还包括出气口塞8，所述出气口塞8经由所述出气口101插接于所述出气通道11内。
在该具体的例子中，当用户不抽吸电子烟时，即电子烟处于非工作状态时，将出气口塞8经由出气口101塞入到出气通道11内，避免发生不必要的泄漏。
参照图5所示，在一个实施例中，所述出气口塞8与所述出气通道11形成密封配合。
在该具体的例子中，由于出气通道11的侧壁为倾斜设置，为了匹配出气通道11，将出气口塞8的侧壁也设置为倾斜，出气口塞8与出气通道11相匹配，二者之间形成紧密的配合关系，进一步防止泄漏的发生。
参照图2所示，在一个实施例中，沿着所述第二中心轴相对于所述第一中心轴偏移的方向，在所述通孔311的两侧，所述雾化面具有第一侧区和第二侧区，所述第一侧区的面积大于所述第二侧区的面积，所述发热体组件设置在所述第一侧区。例如，参照图1，以多孔体31为椭圆柱体、通孔311为椭圆形孔为例，以通孔311的椭圆长轴为基准，在图2所示的方位中，通孔311的椭圆长轴以下的区域为所述第一侧区，通孔311的椭圆长轴以上的区域为所述第二侧区。
在该具体的例子中，参照图2，以多孔体31为椭圆柱体、通孔311为椭圆形孔为例，通孔311在多孔体31上沿椭圆短轴方向朝向一侧偏移，而发热体组件则在雾化面上沿椭圆短轴方向朝向另一侧偏移，即将发热体组件相对于通孔311进行单边布设，可以提高发热体组件的发热效能，使雾化面发热稳定高效，提高雾化面的雾化效果；并且可以将多孔体31在发热体组件这侧的孔边宽度设计最大化，从而改善雾化芯3的强度。在一些实施例中，通孔311与发热体组件间隔开布置。
参照图2所示，在一个实施例中，沿着所述第二中心轴相对于所述第一中心轴偏移的方向，所述多孔体31具有第一径向尺寸，所述预定距离的范围为所述第一径向尺寸的1/5-1/3。
如果通孔311相对于多孔体31偏移的距离过大，则容易造成通孔311旁边一侧的宽度太 小、则多孔体31在这一侧的强度较低，从而影响多孔体31的整体强度质量；如果通孔311相对于多孔体31偏移的距离过小，则不能很好地起到改善气流流动气路的作用。因此，在本实施例中，将通孔311偏移的预定距离定为第一径向尺寸的1/5-1/3，在既能保证改善气流流动的同时，不会影响多孔体31的强度。
参照图2所示，在一个实施例中，所述多孔体31为椭圆柱体，所述通孔311为椭圆形孔，所述雾化面的椭圆短轴与所述通孔311的椭圆短轴相重合，所述雾化面的椭圆长轴相对于所述通孔311的椭圆长轴偏移所述预定距离。
由于电子烟壳体的截面形状多为椭圆形，因此，将多孔体31设置为椭圆柱体，多孔体31的形状与壳体1的形状相互匹配，这样在装配时，多孔体31可以更好地与壳体1内壁相贴合；并且可以在适配壳体1的情况下，将多孔体31的体积做到最大，从而使电子烟的储液腔中的液态基质能够更加顺畅地从多孔体31的吸液面渗透到雾化面，进而提高多孔体31的雾化效率，使用户的抽吸口感更佳。并且，在椭圆形的多孔体31上开设椭圆形的通孔311，这样有助于多孔体31的孔边宽度设计。此外，将通孔311设置为沿着椭圆短轴的方向相对于多孔体31偏移，这样有利于布置长度较长的发热体组件。
参照图3所示，在一个实施例中，所述电子烟雾化装置还包括雾化芯密封件4，所述雾化芯密封件4套设在所述多孔体31的外侧；所述雾化芯密封件4被配置为用于与所述壳体1的内壁形成相互挤压的密封配合。
本实施例中，多孔体31、雾化芯密封件4以及壳体1围合形成所述储液腔102；多孔体31、雾化芯密封件4、壳体1、下盖2围合形成所述雾化腔20。雾化芯密封件4可以提高雾化芯组件与壳体1的内壁之间的密封性能，防止非必要的导通，有效避免漏油的发生。
参照图2所示，在一个实施例中，所述多孔体31的侧部开设有换气通槽301，所述雾化芯密封件4与所述换气通槽301围合形成换气通道，所述换气通道从所述雾化面贯通至所述吸液面。
在该具体的例子中，当烟油通过雾化芯3的多孔体31从其吸液面渗透到雾化面，从而储液腔102中的空气压力减小，同时空气从进气通道21进入雾化腔20中，此时雾化腔20内的气压大于储液腔102内的气压，气体通过由换气通槽301与雾化芯密封件4围合形成的换气通道从雾化腔20进入到储液腔102，从而有效实现储液腔102和雾化腔20的气压平衡，避免出现烟油难以顺畅地从多孔体31的吸液面渗透到雾化面的情况发生，防止出现干烧而影响用户抽吸时的口感。在本实施例中，储液腔102中的烟油能够顺畅地从多孔体31的吸液面渗透到雾化面，雾化面的雾化效果好，用户抽吸口感好。进一步地，当雾化腔20内的气压大于储液腔102内的气压时，雾化芯密封件4在雾化腔20内气压的作用下被顶开，从而气体可以通过换气通槽301从雾化腔20进入到储液腔102；当储液腔102与雾化腔20的气压平衡后，雾化芯密封件4回落覆盖住换气通槽301，防止储液腔102中的液态基质流向雾化腔20。雾化芯3与雾化芯密封件4的配合作用可以实现储液腔102与雾化腔20在用户使用时的换气及密封。
参照图2所示，在一个实施例中，所述换气通槽301设置至少两个。
换气通槽301可以只设置一个，一个换气通槽301便可以起到对储液腔和雾化腔进行换气以保持气压平衡的作用。在该具体的例子中，设置至少两个换气通槽301可以更好地保持储液腔与雾化腔之间的气压平衡。
参照图2所示，在一个实施例中，至少两个所述换气通槽301均匀分布。
当设置多个换气通槽301时，换气通槽301可以为对称的均匀排布，也可以为非均匀排 布；在该具体的例子中，至少两个换气通槽301均匀分布可以使气流更加均衡，提高储液腔与雾化腔之间的气压平衡效果。此外，多个换气通槽301可以设置为相同的形状，也可以设置为不同的形状。所述均匀分布是指换气通槽301相对于多孔体31的中心呈中心对称分布。
参照图3、图4所示，在一个实施例中，所述雾化芯密封件4上设置有凸出部401，所述凸出部401覆盖于所述换气通槽301处。
本实施例中，凸出部401覆盖于换气通槽301靠近储液腔102的一端。雾化芯密封件4上设置有凸出部401与换气通槽301相对应，当储液腔102与雾化腔20之间的气压平衡时，凸出部401覆盖住换气通槽301靠近储液腔102的一端，这样可以起到更好的密封效果，有效防止储液腔102中的液态基质流向雾化腔20；当气压不平衡时，例如当烟油通过多孔体31从其吸液面渗透到雾化面，从而储液腔102的空气压力减小，同时空气从进气通道进入雾化腔20中，此时雾化腔20内的气压大于储液腔102内的气压，雾化芯密封件4在雾化腔20内气压的作用下被顶开，从而气体可以通过换气通槽301从雾化腔20进入到储液腔102，实现气压平衡，防止出现烟油下液不畅及雾化芯3干烧的问题。
参照图3、图4所示，在一个实施例中，所述雾化芯密封件4的外侧面设置有第一弹性凸筋42，所述第一弹性凸筋42抵接在壳体1的内壁上。
在该具体的例子中，第一弹性凸筋42在壳体1的内壁与雾化芯3的多孔体31之间实现过盈配合，从而对多孔体31的外壁面进行密封，也对壳体1的内侧壁进行密封，提高了雾化芯密封件4与壳体1之间的密封效果，防止烟油从电子烟的储液腔102漏油到雾化腔20。
参照图3、图4所示，在一个实施例中，所述雾化芯密封件4上形成有与所述通孔311相匹配的管状结构43，所述管状结构43插接于所述通孔311内。
在该具体的例子中，雾化芯密封件4上的管状结构43插接在多孔体31的通孔311中，对通孔311的周沿进行密封以防止储液腔102中的烟油漏出，管状结构43的设置提高了雾化芯密封件4的密封效果。
参照图2所示，在一个实施例中，所述发热体组件包括发热丝32和电连接于所述发热丝32两端的两个接线盘33，两个所述接线盘33通过所述发热丝32串联连接。
在该具体的例子中，发热丝32主要起到发热的作用，而接线盘33负责与电子烟的导电钉接触并且电性导通。在一些实施例中，导电钉设置有两个，两个导电钉一个为正极、另一个为负极。相应地，接线盘33也设置有两个，同样地，两个接线盘33一个为正极、另一个为负极；在一些实施例中，两个接线盘33分别连接在发热丝32的两端。
在一个实施例中，所述发热丝32的电阻值大于所述接线盘33的电阻值。
在该具体的例子中，发热丝32为细长的长条状，其电阻值大、因此通电之后发热能量较高；而接线盘33为近似于圆盘状，其电阻值较小、通电之后发热能量很小。因此，在本实施例提供的发热体组件中，接线盘33不太发热，热量集中于发热丝32处，发热丝32的发热效果较好、发热能量较高、发热能量易于调节。
参照图2所示，在一个实施例中，所述发热丝32的形状为弧形，且所述发热丝32的弯曲方向与所述通孔311靠近所述发热丝32的孔壁的弯曲方向相同。
在该具体的例子中，发热丝32的弯曲方向与通孔311靠近发热丝32的孔壁的弯曲方向相同，这样发热丝32与通孔311的孔壁之间的间距均匀，从而有利于提高发热丝32发热的均匀性。
参照图5、图6及图10所示，在一个实施例中，所述壳体1在所述出气通道11远离所述出气口101的端口处形成有插接部113，所述插接部113插接于所述通孔311内，所述插 接部113的截面形状为椭圆形。
在该具体的例子中，出气通道11与多孔体31配合处的形状为椭圆形，这样可以使出气通道11与多孔体31配合紧密，提高密封性。并且，出气通道11的外壁面与壳体1的内壁面之间具有均匀的空间区域，在这一宽度均匀的空间区域内，零部件的设置及装配比较方便容易。本实施例中，整个出气通道11的截面均为椭圆形。
参照图5、图6所示，在一个实施例中，所述电子烟雾化装置还包括导电钉5，所述导电钉5穿设在所述下盖2上，所述导电钉5与所述发热体组件接触并形成电连接。
该电子烟雾化装置还包括导电钉5，所述导电钉5穿设在所述下盖2上，所述导电钉5抵接在所述多孔体31的雾化面设置有发热体组件的位置处，所述导电钉5与所述发热体组件接触并形成电连接。所述导电钉5用于将雾化芯与其它的供电器件形成电连接。在一些实施例中，导电钉5设置有两个，两个导电钉5分别与两个接线盘33接触并形成电连接。
在本申请实施例提供的电子烟雾化装置中，导电钉5直接与设置在雾化芯3的雾化面上的发热体组件接触导通形成电连接，其连接关系简单、安装方便、易于装配操作。
此外，发热体组件与多孔体31为一体成型的结构。在一些实施例中，该发热体组件的制成工艺为：先对多孔体31进行烧结，再在多孔体31上采用金属粉末印刷发热体组件，最后通过烧结工艺将发热体组件与多孔体31结合为一个整体结构。发热体组件与通孔311间隔开布置。该一体成型形成的发热体组件在多孔体31上结合紧密、可靠，并且发热体组件不会额外占用电子烟内部的空间；发热体组件与导电钉5接触时，相当于导电钉5与多孔体31之间形成面与面的抵接关系，这样的连接简单、稳固。
在一个实施例中，所述壳体1的内壁设置有第一支撑筋12，所述导电钉5与所述第一支撑筋12分别从所述电子烟雾化装置的两侧对所述电子烟雾化装置形成限位抵接。
在该具体的例子中，第一支撑筋12从雾化芯密封件4的上端面处对雾化芯密封件4进行过盈预压，导电钉5从雾化芯密封件4的下端面处对雾化芯密封件4进行过盈预压，确保连接的紧密可靠性。
参照图5、图7、图8及图10所示，在一个实施例中，所述壳体1的内壁设置有第一支撑筋12，所述下盖2上设置有第二支撑筋22，所述第一支撑筋12与所述第二支撑筋22分别从所述电子烟雾化装置的两侧对所述电子烟雾化装置形成限位抵接。本实施例中，第一支撑筋12及第二支撑筋22均沿着壳体1的长度方向延伸。
在该具体的例子中，第一支撑筋12从雾化芯密封件4的上端面处对雾化芯密封件4进行过盈预压，第二支撑筋22从雾化芯密封件4的下端面处对雾化芯密封件4进行过盈预压，第一支撑筋12及第二支撑筋22均对软胶材质的雾化芯密封件4的端面具有一定的压缩量，确保连接的紧密可靠性，从而确保电子烟雾化装置在壳体1内得到可靠、稳定的定位和固定，壳体1以及下盖2之间也无需再设置其它用于固定电子烟雾化装置的相关结构，简化了电子烟的内部结构，雾化芯密封件4在壳体1与雾化芯3之间形成有效密封。并且还能够确保导电钉5与发热体组件抵接连通的可靠性。
进一步地，第一支撑筋12能够避免雾化芯密封件4向储液腔102一侧偏离，第二支撑筋22能够避免雾化芯密封件4向雾化腔20一侧偏移，这样使电子烟雾化装置的内部结构更加稳定。
参照图3、图4、图5所示，在一个实施例中，所述雾化芯密封件4上设置有顶持部41，所述顶持部41与所述第二支撑筋22抵接以轴向固定所述电子烟雾化装置。
在该具体的例子中，顶持部41是设置在雾化芯密封件4上的倒扣结构，即顶持部41从 雾化芯3的底部对雾化芯3进行轴向固定；装配后，顶持部41与下盖2上设置的第二支撑筋22的位置相对应，顶持部41与第二支撑筋22相互抵接以对雾化芯3进行轴向定位，确保电子烟雾化装置能够较为稳固地固定于壳体1内。
在一个实施例中，所述壳体1与所述下盖2通过卡扣卡接。
在该具体的例子中，壳体1与下盖2之间采用卡扣卡接的连接方式装配起来操作比较方便容易，当壳体1与下盖2卡接到位后，导电钉5与发热体组件抵接到位，这样的装配方式有利于对导电钉5和发热体组件进行定位及固定。
参照图6-图9所示，在一个实施例中，所述进气通道21包括相互连通的进气管道211和进气口212，所述进气口212设置于所述进气管道211的靠近所述雾化腔20的位置；所述进气口212设置至少两个，且至少两个所述进气口212间隔设置，至少两个所述进气口212围绕所述进气管道211的轴线分布在进气管道211的侧部。
在该具体的例子中，将位于进气管道211与雾化腔20之间的进气口212设置在进气管道211的侧部，并且设置至少两个相互隔离的进气口212，当外界大气气流从进气管道211流入到进气口212时，气流可以侧向进入到至少两个分支通道内，即侧向进入到至少两个进气口212内，至少两个进气口212可以对气流进行分流，气流流动的轨迹不会发生明显改变，气流不会产生涡流，气流会以一个较为缓和的状态进行流动进而进入到雾化腔20内，进入雾化腔20中的空气气流与发热体组件加热雾化产生的烟雾充分混合后，通过出气通道11进入到用户口腔中。
参照图5所示，在一个实施例中，所述电子烟雾化装置还包括设置于所述下盖2内的吸油元件6，所述吸油元件6环绕设置在所述进气管道211的外周；所述吸油元件6靠近所述雾化腔20的一端的端面低于所述进气口212的端面。
在本申请实施例提供的电子烟雾化装置中，雾化腔20的体积相对于现有技术能够做到更大，进而能够将吸油元件6的体积设置到更大，提高吸油元件6的吸油能力，保障雾化腔20内的液体能够被吸油元件6吸收，以避免出现漏油的现象。另一方面，没有被吸出的烟雾气溶胶在冷却后会形成冷凝液滴，由于电子烟雾化装置的内部空间得到增大，所以可以设置用于收集冷凝液滴的部件，降低冷凝液滴从电子烟上漏出的可能性。
例如，进气通道21进入的空气与雾化腔20内的烟雾相遇，会存在部分烟雾未被吸出，进而冷凝为液滴。如图1所示，冷凝液滴可以被设置在下盖2上的吸油元件6吸收，避免液滴从进气通道21处漏出。
此外，在该实施例中，吸油元件6靠近雾化腔20的端面低于进气口212所在一侧的端面，这样使吸油元件6上的液体不会从进气口212流入到进气通道21中，避免了从进气通道21漏油的问题。
在一个实施例中，所述吸油元件6的厚度为3mm-6mm。
现有技术中，由于壳体1内还设置有上支架、下支架及上支架密封件，其占据了壳体1内很大的空间，因此现有技术中的吸油元件的厚度只能设置为1.5mm左右。而在本实施例中，如前所述，由于雾化腔20的体积相对于现有技术能够做到更大，进而能够将吸油元件6的体积设置到更大，吸油元件6的厚度可以达到3mm-6mm，吸液量可以增加2-4倍，从而可以将烟弹生命周期内产生的冷凝液都储存在吸油元件6中，避免过多的冷凝液从下盖2的进气通道21溢出，或者从出气通道11进入到用户口中。
此外，在本申请实施例提供的电子烟雾化装置中，冷凝液在倾斜设置的出气通道11的内壁面上难以停留，冷凝液会向下滴落，进而被吸油元件6吸收，从而避免进入用户口中。
参照图5所示，在一些实施例中，所述多孔体31、雾化芯密封件4以及所述壳体1合围形成所述储液腔102。雾化芯密封件4在壳体1的内壁与多孔体31之间形成密封作用。多孔体31对壳体1内的空间形成划分作用。如图1所示，位于壳体1内、雾化芯密封件4上方的区域可以作为储液腔102。雾化芯密封件4上可以留有孔洞，以便储液腔102内的烟油与多孔体31接触。储液腔102的烟油能够被多孔体31吸入，进而使烟油流通至发热体组件处。发热体组件发热能够对烟油进行雾化。
在一些实施例中，所述通孔311分别与所述出气通道11及所述雾化腔20连通。通孔311将出气通道11与雾化腔20连通。雾化腔20内的烟雾经通孔311进入到出气通道11后经由出气口101被用户吸入。在本实施例中，雾化腔20内的烟雾进入出气通道11的路径变短，提高了烟雾吸入的效率。例如，空气经进气通道21进入雾化腔20后，带着烟雾经通孔311进入出气通道11。
参照图3、图4所示，在一个实施例中，所述雾化芯密封件4上形成有与所述通孔311相匹配的管状结构43，所述管状结构43插接于所述通孔311内，且所述出气通道11和雾化腔20通过所述管状结构43连通；所述壳体1在所述出气通道11远离所述出气口101的端口处形成有插接部113，所述插接部113插接固定在所述管状结构43内。
在该具体的例子中，雾化芯密封件4上的管状结构43插接在通孔311中，对通孔311的周沿进行密封以防止储液腔102中的烟油漏出；同时管状结构43又使得出气通道11与雾化腔20通过管状结构43形成连通，即雾化腔20中的气雾与空气的混合物可以通过管状结构43进入出气通道11，进而被用户吸食。为了提高对储液腔102的密封效果，降低液体外漏的风险。管状结构43的设计可以对通孔311起到一定程度的密封作用，将通孔311与储液腔102隔开，这样，储液腔102中的液体不易从通孔311处泄漏。管状结构43在通孔311与插接部113之间形成密封，以避免管状结构43与通孔311之间出现漏油的问题。将出气通道11的插接部113插接固定在管状结构43中，也能够提高雾化芯密封件4以及雾化芯3两者整体的固定、定位可靠性。通过上述插接配合关系，出气通道11直接通过管状结构43以及通孔311与雾化腔20连通，这种气路结构顺畅、弯折较少，有助于雾化后的气体向外流出，降低其冷却形成冷凝液滴的可能性。
参照图3、图4所示，在一个实施例中，所述管状结构43的内侧壁设置有第二弹性凸筋44，所述第二弹性凸筋44与所述插接部113相抵接。
在该具体的例子中，第二弹性凸筋44紧紧地抵接住插接部113，在雾化芯3的通孔311与插接部113之间形成过盈配合，即第二弹性凸筋44对雾化芯3的内壁面进行密封，也对壳体1的出气通道11的外侧壁进行密封，从而防止烟油从储液腔102漏油到雾化腔20。
参照图3、图10及图11所示，在一个实施例中，所述壳体1在所述插接部113的周围形成有台阶面110；所述雾化芯密封件4上形成有密封沿431，所述密封沿431位于所述管状结构43的一端，所述台阶面110与所述密封沿431抵接。
在该具体的例子中，所述密封沿431位于所述多孔体31的吸液面上并且环绕在所述通孔311周围，密封沿431在台阶面110与多孔体31的吸液面之间形成密封，以对管状结构43与通孔311之间形成进一步的密封效果。密封沿431与台阶面110的配合结构能够起到良好的密封作用，防止液体穿过出气通道11与多孔体31之间的缝隙进而泄漏到通孔311、雾化腔20以出气通道11中。密封沿431的一部分环绕吸液面的边沿设置，并且有一部分环绕在通孔311的周围设置。密封沿的环绕通孔311的部分在台阶面110与吸液面之间形成密封。具体地，密封沿431在通孔311的孔口外侧的吸液面部分与台阶面110之间形成密封作用。
参照图5、图6所示，在一些实施例中，在本申请所述的电子烟雾化装置中，还包括下盖密封件7，所述下盖密封件7与壳体1的内壁抵接，并在下盖2与壳体1的内壁之间形成密封。壳体1与雾化芯密封件4以及多孔体31围合形成所述储液腔102，雾化芯密封件4套设在多孔体31上，雾化芯密封件4、壳体1以及多孔体31之间过盈配合。储液腔102中的液体，例如烟油，被传导至多孔体31的吸液面，并经多孔体31的毛细作用传导至多孔体31的雾化面，经设置在雾化面上的发热体组件加热雾化形成烟雾。雾化面与下盖2之间形成雾化腔20，烟雾位于雾化腔20中，雾化腔20与下盖2上的进气通道21连通，用户在出气口101的抽吸作用，带动外界空气从进气通道21进入雾化腔20中，携带雾化腔20的烟雾导出至出气通道11，供用户吸食。随着烟雾的生成，烟油逐渐被多孔体31吸附到其雾化面一侧，储液腔102一侧的气压下降，形成负压；而雾化腔20一侧的气压较高，空气会通过多孔体31的微孔从雾化面向其吸液面渗透到储液腔102，并且，雾化芯密封件4在雾化腔20气压的作用下被顶开，气体通过换气通槽301从雾化腔20进入到储液腔102，从而有效实现气压平衡；与此同时，使得电子烟雾化装置上能够吸附充足的烟油保持烟雾的生成效果。经发热体组件加热形成的烟雾遇雾化腔20中的冷空气易冷却形成烟油，通过在下盖2的进气通道21周围设置吸油元件6，且吸油元件6靠近出气通道11的一端的端面低于进气口212的端面，该吸油元件6能够吸收经冷凝形成的烟油，且该烟油不会从进气通道21漏出，防止了漏油。
此外，在本申请的实施例中，由于取消了三个零件(上支架、上支架密封件、下支架)，下盖2中设置的用于固定导电钉的固定柱23可以成倍加高，加高后的固定柱23的结构强度增加，从而改善铆接装配导电钉时，下盖铆接孔开裂、影响到雾化腔中的冷凝液从导电钉孔开裂区域漏液的问题。
在本申请的又一个实施例中，提供了一种电子烟，该电子烟包括如上所述的电子烟雾化装置和电源。
该电子烟雾化芯的多孔体31上设置的通孔311为偏心孔，可以帮助改善电子烟中的气流的流动气路，提高外界进入电子烟的空气与电子烟内产生的烟雾之间混合的均匀度，电子烟抽吸的口感更佳。并且，该电子烟可以确保出气口101的居中设置，使该电子烟外观美观并且用户抽吸时舒适感较高。
该电子烟内部的零部件较少，装配更加简单，生产效率较高。同时，该电子烟的容纳腔具有更大的空间，能够设置更大体积的吸油元件6，从而提高雾化腔20内吸液体的吸液能力。这样能够有效地避免冷却后的液体随烟雾被用户吸入或从进气通道21漏出的问题发生。
根据本申请的实施例，在用户使用电子烟时，用户通过出气口101抽吸。外部空气经进气通道21进入雾化腔20。电子烟内的传感器感测到用户抽吸的动作，电源与发热体组件之间的电连接导通并向发热体组件供电，以加热雾化储液腔102中的液体形成烟雾，空气进入雾化腔20带动烟雾经由出气通道11被用户吸入。
进入雾化腔20内的空气会导致烟雾冷凝并形成冷凝液被吸油元件6吸收，避免液体被烟雾带走被用户抽吸或者液体积攒过多造成漏液。
上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
虽然已经通过示例对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进行修改。本申请的范围由所附权利要求来限定。
