背景技术
电子烟作为一款健康方便的消费品，近年来得到消费者的青睐，使用越来越普及。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。为了便于用户携带、使用电子烟，电子烟产品具有紧凑、小巧的外形设计。这种设计方式导致电子烟产品内部的结构十分紧凑。
有限的空间使得电子烟产品内部的结构容易存在一些功能上的缺陷。例如，现有的电子烟产品存在漏油和供液不畅的问题。在对烟油进行雾化处理的过程，需要烟油能够流动到雾化器件所在的区域。烟油的泄漏或者烟油无法充分流动至雾化器件，这都会极大地降低用户的使用体验。有必要对电子烟产品的结构进行改进。

应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
下面结合附图具体描述根据本公开实施例的电子烟雾化装置100。
参见图1至图8，根据本公开实施例的电子烟雾化装置100包括壳体10、雾化组件20和第一密封件30。其中，壳体10内设置有储油仓13和雾化组件20。壳体10可以采用弹性半透明或透明材料制成。储油仓13用于液体存储烟油，雾化组件20主要用于对烟油等液体进行雾化产生气溶胶(烟雾)，壳体10上设置有与外界大气连通的气流通道11。环境中空气和经雾化组件20加热雾化产生的烟雾可以通过气流通道11导入和导出。
雾化组件20主要由多孔体和发热体组成，多孔体可以采用多孔陶瓷结构。多孔体具有相对设置的吸液面和雾化面，发热体设置在多孔体的雾 化面。烟油可以经吸液面传导至雾化面，在发热体的作用下雾化形成烟雾，并从雾化面导出。多孔体上设置有至少一个换气通道21，换气通道21的一端与储油仓13连通，换气通道21的另一端与外界大气连通。
第一密封件30套设在雾化组件20上，第一密封件30上设置有第一通孔32，第一通孔32可以用于供第一密封件30导气和导油。第一密封件30对雾化组件20进行密封，防止储油仓中的烟油从除吸液面以外的地方流入雾化腔。第一密封件30包括至少一个与换气通道21相对应的密封部31。密封部31可以打开和封闭换气通道21，以便于允许外界大气进入储油仓13，同时可以阻止储油仓13中的液体流出。
当用户抽吸时，电子烟内的传感器被触发，发出信号驱使雾化组件20开始加热，多孔体中液体在雾化面被加热雾化，雾化形成的烟雾经由雾化腔进入到壳体10的气流通道11中共用户抽吸。当储油仓中的烟油逐渐减少，储油仓13中的气压下降，形成负压。雾化腔71中的气压较高，空气会顶开密封部31进而流通到储油仓13，实现气压平衡。从而保证多孔体上能够吸附充足的烟油保持雾化效果。
在本公开中，在电子烟雾化装置100的工作过程中，烟油由多孔体的吸液面进入到多孔体中，并在多孔体的雾化面通过发热体的加热作用，雾化形成烟雾被导出，由于烟油不断被雾化消耗，此时储油仓13处于负压状态，需要外界的空气补充至吸液面以恢复内外压差平衡。此时，通过第一密封件30中的密封部31被气流顶起变形，密封部31打开换气通道21，空气通过换气通道21进入储油仓13，达到了良好的换气效果，避免供油不畅和糊芯的问题。
由此，本公开的电子烟雾化装置100，通过在雾化组件20上设置换气通道21，在第一密封件30上设置一个与换气通道21相对应的密封部31，并通过密封部31打开和封闭换气通道21，使外界大气可以进入储油仓13，实现电子烟雾化装置100内的气压平衡，确保电子烟雾化装置100供液顺畅，使电子烟雾化装置100能够实现完全雾化，提高用户使用体验。同时该电子烟雾化装置100还能阻止储油仓13中液体流出，防止漏油。
根据本公开的一个实施例，结合图1、参见7和图8，换气通道21沿 吸液面到雾化面的延伸方向贯通。储油仓13处于负压状态时，密封部31打开换气通道21，空气通过换气通道21进入储油仓，使得内外气压平衡，供油更加顺畅。
在本公开中，密封部31可以在第一状态和第二状态之间切换。密封部31在第一状态下，此时，密封部31封闭换气通道21，阻止储油仓13中的液体流出。密封部31在第二状态下，密封部31打开换气通道21，以允许外界大气通过换气通道21进入储油仓13，储油仓13内外压差平衡，供油更加顺畅。
可选地，密封部31在第二状态下，密封部31朝向储油仓13的方向变形，以打开换气通道21，允许外界大气进入储油仓13。密封部31在第一状态下，密封部31朝向雾化组件20的方向变形，以封闭换气通道21。
根据本发明的一个实施例，如图1、图5、图6和图9所示，壳体10内还设置有第一盖体40和第二盖体50，第一盖体40与第二盖体50限定出容纳腔，雾化组件20设置在容纳腔内，第一盖体40设置有避让槽41和下液孔42，避让槽41与下液孔42连通，并且避让槽41与气流通道11连通。吸液面通过下液孔42与储油仓13连通；换气通道21通过与下液孔42连通的避让槽41与外界大气连通。
在本公开的一些具体实施方式中，参见图1和图2，电子烟雾化装置100还包括第二密封件60，第二密封件60安装在壳体10内。并且第二密封件60的外缘抵接壳体10的内壁，使第二密封件60与壳体10合围形成储油仓13。
根据本公开的一个实施例，在储油仓13中的气压大于或等于外界大气压的情况下，密封部31处于第一状态，此时，密封部31封闭换气通道21，阻止储油仓13中的液体流出。在储油仓13中的气压小于外界大气压的情况下，密封部31处于第二状态。密封部31打开换气通道21，以允许外界大气通过换气通道21进入储油仓13，使储油仓13内外压差平衡，供油更加顺畅。
在本公开中，参见图2、图3和图4，第一密封件30的上边沿抵接在雾化组件20上，密封部31位于第一密封件30的上边沿的内壁。密封部 31处于第一状态，密封部31覆盖换气通道21，以封闭换气通道21，阻止储油仓13中的液体流出。密封部31处于第二状态，密封部31朝向储油仓13的方向变形，以打开换气通道21，允许外界大气通过换气通道21进入储油仓13。
根据本公开的一个实施例，参见图7和图8，换气通道21的数量为多个，多个换气通道21沿发热体间隔开布置，密封部31和避让槽41的数量分别与换气通道21的数量对应。
在密封部31处于第一状态时，每个密封部31可以分别覆盖与其对应的换气通道21。第一密封件30可以采用弹性材料件。例如第一密封件30和密封部31均可以采用软胶等具有一定弹性形变能力的材料，保证密封部31在第一状态和第二状态切换时，可以实现变形，以打开或封闭换气通道21。根据本公开的一个实施例，第一密封件30为硅胶材料，密封部31为硅胶片。
根据本公开的一个实施例，参见图7和图8，换气通道21为设于多孔体的外侧表面的凹槽，凹槽沿吸液面到雾化面的延伸方向贯通多孔体。第一密封件30套设在雾化组件20上，凹槽与第一密封件30的内壁配合形成换气通道21。
在本公开中，换气通道21的数量为多个，多个换气通道21间隔设置在多孔体的外侧壁。密封部31的数量以及设置位置可以与换气通道21一一对应。需要说明的是，凹槽的形状不特别限制，在不同的实施例中，凹槽的截面形状还可以是侧面开口的三角形、矩形或不规则形状。由于凹槽的侧面开口，在进行多孔体的装配时，可通过第一密封件30封闭凹槽的侧面开口，以形成换气通道。
在一个实施例中，换气通道21为沿吸液面到雾化面的延伸方向贯通多孔体的通孔。可选地，换气通道21的数量为多个，多个换气通道21间隔设于多孔体的外周内缘。通孔的截面可以为圆形。需要说明的是，通孔的形状不特别限制，在不同的实施例中，通孔的截面形状还可以是椭圆形、三角形、矩形或不规则形状。并且密封部31的数量以及设置位置与换气通道21一一对应。
在本公开的一些具体实施方式中，如图3和图4所示，以沿吸液面至雾化面的延伸方向为预设方向，第一密封件30垂直于预设方向的截面为长形结构，多个密封部31位于长形结构的两端。密封部31的数量为4个，4个密封部31两两对称分布在长形结构的两端。当然，本领域技术人员可以理解，密封部31的具体个数，每个密封部31的具体尺寸、厚度等可以根据实际需要进行具体限定。
在本公开的一个实施例中，如图3和图4所示，第一密封件30的上边沿抵接在雾化组件20上，密封部31位于第一密封件的上边沿的内壁。
在本公开中，如图1和图2所示，第一盖体40与第一密封件30过盈配合，第一密封件30与雾化组件20过盈配合。第一密封件30与雾化组件20过盈配合。
根据本公开的一个实施例，多孔体的雾化面与第二盖体50之间形成雾化腔71，雾化后产生的烟雾导入雾化腔71，最后通过气流通道11导出。第二盖体50设有与气流通道11连通的多个通气孔51。空气经过通气孔51进入到雾化腔71中。多个通气孔51可以使得空气均匀的流入，保持雾化腔71中的烟气与空气均匀混合。而均匀排布的多个通气孔51也增加了空气流入时的空气阻力。用户在通过气流通道11吸气时能感受到足够的空气阻尼，提高了抽吸烟气的体验效果。
在本公开的一些具体实施方式中，电子烟雾化装置100还包括：下盖81，下盖81设于第二盖体50的下端并与壳体10相配合，下盖81设有进气孔12，进气孔12与通气孔51连通。用户吸气时，外界的空气经过进气孔12后，再经过通气孔51，之后进入雾化腔71。
在一种可选的实施方式中，换气通道21的一端与储油仓13连通，换气通道21的另一端与雾化腔71连通，换气通道21通过雾化腔71与外界大气连通。在储油仓13的气压因烟油减少而降低的情况下，由于雾化腔71与进气孔12连通，雾化腔71的气压与外界一致，相对于储油仓13的气压更高，所以，密封部31会被雾化腔71一侧的空气顶开，空气进入到储油仓13，实现气压平衡。
如图1、图10和图11所示，电子烟雾化装置100还下盖密封件，下 盖密封件82环绕设置于下盖81的外周，并且下盖密封件82的外缘抵接壳体10的内壁。第二密封件60、雾化组件20和下盖密封件82用于提供电子烟雾化装置100内部必要的密封性，避免储油仓13以及各元件的连接间隙之间存在非必要的导通，有效避免漏油的发生。下盖密封件82采用软质材料制成，下盖密封件82设置有密封筋并且可与下盖81及壳体10过盈配合，以实现与外界的隔离。
在一实施例中，参见图1和图2，电子烟雾化装置100还包括吸液体83，吸液体83环绕设置于进气孔12的外周，吸液体83用于吸收进气孔12流出的冷凝液体。
在一实施例中，参见图1和图2，电子烟雾化装置100还包括导电钉，导电钉通过下盖81中的安装孔811与发热体电连接，用于电源的接入。
当然，在本公开中，电子烟雾化装置100的其他结构是可以理解并且能够实现的，在本公开中不再详细赘述。
总而言之，本公开的电子烟雾化装置100，通过在雾化组件20上设置换气通道21，在第一密封件30上设置一个与换气通道21相对应的密封部31，并通过密封部31打开和封闭换气通道21，使外界大气可以进入储油仓13，实现电子烟雾化装置100内的气压平衡，确保电子烟雾化装置100供液顺畅，使电子烟雾化装置100能够实现完全雾化，提高用户使用体验。同时还能阻止储油仓13中液体流出，造成漏油。
本公开还提供一种电子烟，包括上述实施例中的电子烟雾化装置100。由于根据本公开的电子烟雾化装置100具有上述技术效果，因此，根据本公开实施例的电子烟也应具备相应的技术效果。即本公开的电子烟可以有效解决壳体10内液体供液不顺畅和漏油的问题。
在本公开中，参见图1和图2，电子烟的原理是储油仓13中的液体导入雾化组件20的吸液面中。当用户抽吸时，电子烟内的传感器被触发，发出信号驱使雾化组件20开始加热，液体在雾化面被加热雾化，空气经由进气孔12进入，带走雾化腔71中的烟雾和空气。烟雾和空气经过第一盖体40以及第二密封件60上的管道进入气流通道11，最终进入用户嘴里。储油仓中的烟油减少，储油仓13中的气压下降，形成负压。雾化腔71一侧 的气压较高，空气会顶开密封部31进而流通到储油仓13，实现气压平衡。进一步地，使得多孔体上能够吸附充足的烟油保持烟雾的生成效果。
由于在雾化组件20的多孔体上添加贯通的孔或者槽(换气通道21)，在电子烟工作过程中，烟油通过烟油通道从吸液面达到雾化面，而空气通过添加的换气通道21补充至储油仓13，达到了良好的换气效果。解决了漏油和下油不畅现象。
在本公开中，气溶胶产生装置100的其他结构是可以理解并且能够实现的，在本公开中不再详细赘述。
虽然已经通过例子对本公开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，以上例子仅是为了进行说明，而不是为了限制本公开的范围。本领域的技术人员应该理解，可在不脱离本公开的范围和精神的情况下，对以上实施例进行修改。本公开的范围由所附权利要求来限定。
