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。

具体实施方式
现在将参照附图来详细描述本申请的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术和设备可能不作详细讨论，但在适当情况下，所述技术和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
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。
参照图1-图7所示，根据本公开的一个实施例，提供了一种电子烟雾化装置，其包括壳体1、下盖2及雾化芯组件，所述壳体1包括出气口101和开口端，所述壳体1内设置有出气通道11，所述出气通道11与出气口101连通；所述下盖2盖设于所述壳体1的开口端；所述雾化芯组件设置于所述壳体1内；所述壳体1与所述雾化芯组件围合形成储液腔102；所述雾化芯组件与所述下盖2之间的区域形成雾化腔20，所述雾化腔20分别与所述出气通道11以及外界连通；所述壳体1的内侧壁开设有换气槽103，所述雾化芯组件与所述换气槽103合围形成换气通道，或者所述雾化芯组件及所述下盖2共同与所述换气槽103合围形成换气通道；所述换气通道与所述储液腔102及所述雾化腔20均连通，即：换气槽103连通所述储液腔102和所述雾化腔20；所述换气槽103用于维持所述储液腔102与所述雾化腔20之间的气压平衡。
进一步地，所述下盖2开设有与外界连通的进气通道21，所述进气通道21还与所述雾化腔20连通；进一步地，所述雾化芯组件与所述下盖2之间存在间隙，所述换气通道通过所述间隙与所述雾化腔20连通。所述雾化芯组件包括多孔体31和发热体组件32，所述多孔体31具有吸液面和雾化面，所述发热体组件32设置于所述多孔体31的所述雾化面处；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32接触并形成电连接。
本申请实施例提供的电子烟雾化装置的工作原理为：存储在电子烟储液腔102中的烟油不断渗透至多孔体31的吸液面，吸液面吸收烟油传导至雾化面；当用户使用该电子烟雾化装置在出气口101处抽吸时，内部的传感器被触发， 从而发出信号驱使设置在雾化面上的发热体组件32对烟油进行加热产生气溶胶，烟油在雾化腔20中被加热雾化，外界气流经由下盖2的进气通道21进入，带走雾化腔20中的烟雾，再经过壳体1内的出气通道11，最终从出气口101进入到用户口腔中。
在本申请实施例提供的电子烟雾化装置中，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，气体便可以通过换气通道从雾化腔20进入到储液腔102中，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，防止雾化芯3出现干烧而影响用户抽吸时的口感。也就是说，换气通道具有闭合状态及打开状态；在雾化腔20的气压高于储液腔102的气压时，因为气压差的存在，换气通道出现气体流通，换气通道处于打开状态，并将气体从雾化腔20经由换气通道导入储液腔102，以维持储液腔102与雾化腔20之间的气压平衡。因此，在本申请实施例提供的电子烟雾化装置中，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，储液腔102内的负压可以通过换气通道及时补充空气，提高了恢复储液腔与雾化腔压差的响应速度，且可以使雾化芯3的多孔体31能够吸附充足的烟油以保持烟雾的生成效果，雾化面的雾化效果更好，用户抽吸口感及抽吸体验更好。
并且，在本申请实施例提供的电子烟雾化装置中，将换气槽103开设在壳体1的内侧壁处，不仅开设方便，并且无需在雾化芯组件上开设专门的换气通道，这样就不会破坏雾化芯组件的结构，从而不会影响雾化芯组件的强度。
此外，相比于现有传统的电子烟雾化装置，在本申请实施例提供的电子烟雾化装置中，首先，只采用壳体1与下盖2配合的形式对雾化芯组件等结构进行限位，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。其次，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。并且，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。
参照图1所示，在一个实施例中，进一步地，所述壳体1内设置有支撑筋12，所述支撑筋12与所述下盖2分别从所述雾化芯组件的两侧对所述雾化芯组件形成限位抵接。
在该具体的例子中，支撑筋12从雾化芯组件的上端面处对雾化芯组件进行过盈预压，下盖2从雾化芯组件的下端面处对雾化芯组件进行过盈预压，从而确保连接的紧密可靠性。
在一个实施例中，所述雾化芯组件包括多孔体31以及套接在所述多孔体31外侧的雾化芯密封件4，所述雾化芯密封件4与所述换气槽103合围形成所述换气通道，或者所述雾化芯密封件4及所述下盖2共同与所述换气槽103合围形成所述换气通道。
进一步地，所述雾化芯密封件4及所述下盖2共同与所述换气槽103合围形成所述换气通道，所述雾化芯密封件4与所述换气槽103合围形成第一通道，所述下盖2与所述换气槽103合围形成第二通道，所述第一通道与第二通道连通构成所述换气通道。
参照图1、图2、图6所示，在一个实施例中，进一步地，所述雾化芯密封件4包括本体部41和弹性件42，所述弹性件42与所述本体部41连接；
所述弹性件42的位置与所述换气槽103的位置相对应，在所述换气通道处于闭合状态的情况下，所述弹性件42与所述壳体1的内侧壁贴合；在所述换气通道处于打开状态的情况下，所述弹性件42与所述壳体1的内侧壁分离。
在该具体的例子中，换气通道的打开及闭合由设置在雾化芯密封件4的本体部41上的弹性件42实现；具体地，当储液腔102与雾化腔20的气压平衡时，弹性件42与壳体1的内侧壁贴合以使换气通道处于闭合状态，从而防止储液腔102中的液态基质流向雾化腔20；当雾化腔20内的气压大于储液腔102内的气压时，雾化腔20内的气流顶开弹性件42，弹性件42与壳体1的内侧壁分离以使换气通道处于打开状态，从而气体便可以通过换气通道从雾化腔 20进入到储液腔102中，从而有效实现储液腔102和雾化腔20的气压平衡。
在一个实施例中，进一步地，所述本体部41具有朝向所述储液腔102的第一表面，所述弹性件42为片状，所述弹性件42的一侧连接于所述第一表面的边缘位置处，并且另一侧朝向所述储液腔102的方向凸出设置。
在该具体的例子中，弹性件42为设置在本体部41上的片状结构，其位于本体部41的第一表面的边缘处，与换气槽103的位置相对应；当储液腔102和雾化腔20的气压平衡时，弹性件42便与壳体1的内侧壁贴合，此时储液腔102与换气槽103隔离，以防止储液腔102中的液态基质流向雾化腔20；当雾化腔20内的气压高于储液腔102内的气压时，弹性件42被来自雾化腔20内的气流顶开，此时换气槽103与储液腔102连通，以使气体通过换气槽103从雾化腔20进入到储液腔102中，从而有效实现储液腔102和雾化腔20的气压平衡。
在一个实施例中，进一步地，所述本体部41和所述弹性件42为一体成型设置。
在该具体的例子中，在本体部41上一体成型形成弹性件42，这样的成型方式制作工艺简单易操作，并且本体部41与弹性件42之间的连接非常紧密牢固。
在一个实施例中，所述换气槽103数量为一个。
在该具体的例子中，设置一个换气槽103便可以起到对储液腔102和雾化腔20进行换气以保持气压平衡的作用。相应地，弹性件42也只需设置一个即可。
在一个实施例中，所述换气槽103的数量为至少两个，且所述换气槽103的数量与所述弹性件42的数量相对应。
在该具体的例子中，设置至少两个换气槽103可以更好地保持储液腔102与雾化腔20之间的气压平衡。进一步地，弹性件42也设置至少两个，弹性件42与换气槽103一一对应设置。
在一个实施例中，进一步地，至少两个所述换气槽103相对所述壳体1的轴线均匀分布。
当设置多个换气槽103时，换气槽103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，至少两个换气槽103均匀分布可以使气流更加均衡，提高储液腔102与雾化腔20之间的气压平衡效果。所述均匀分布是指换气槽103相对于壳体1的轴线呈中心对称分布。所述壳体1的轴线即壳体1的中心轴，亦即图1中沿S方向的轴线。
在一个实施例中，进一步地，所述换气槽103的延伸方向与所述壳体1的轴线平行。
由于储液腔102与雾化腔20沿着与壳体1的轴线平行的方向排布，因此将换气槽103的延伸方向设置为与壳体1的轴线平行可以更好地实现经由换气槽103为储液腔102与雾化腔20进行换气，保持储液腔102与雾化腔20之间的气压平衡。
在一个实施例中，进一步地，所述换气槽103的截面形状为矩形；进一步地，所述矩形的长边的延伸方向与所述壳体1的轴线平行。
此外，多个换气槽103可以设置为相同的形状，也可以设置为不同的形状；换气槽103的具体形状还可以为圆形、椭圆形、三角形、半圆形、梯形或者其他不规则形状。
参照图4所示，在一个实施例中，所述壳体1的内侧壁开设有用于与所述下盖2配合卡接的卡口104。
进一步具体地，在下盖2上设置有与卡口104相匹配的卡扣结构，该卡扣结构与卡口104匹配卡接，这样壳体1与下盖2装配起来操作比较方便容易；并且当壳体1与下盖2卡接到位后，导电钉5与发热体组件32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32进行定位及固定。
参照图4所示，在一个实施例中，进一步地，所述换气槽103设置在与所述卡口104对应的位置处。
在该具体的例子中，将换气槽103开设在与卡口104对应的位置处，这样对于模具成型比较容易，方便制作。当然，换气槽103的开设位置不限于此，还可以开设在其他位置处。
参照图3所示，在一个实施例中，所述出气通道11具有沿所述壳体1的轴向分布的第一气流段111和第二气流段112，其中第一气流段111与所述出气口101连接，所述第二气流段112靠近所述雾化芯组件设置；所述第二气流 段112的横截面积大于所述第一气流段111的横截面积。
在该具体的例子中，出气通道11中靠近雾化芯组件的第二气流段112拥有更大的横截面积，这样可实现大体积空间的气流通道，使雾化腔20雾化后的气熔胶汇聚到第二气流段112的大空间区域，从而调节电子烟的抽吸吸阻大小，调节客户的抽吸口感。具体地，雾化芯3对储液腔102中的液体进行加热雾化后，加热雾化形成的大颗粒气溶胶首先进入到第二气流段112，由于第二气流段112的横截面积大于第一气流段111的横截面积，也就是壳体1的进气口侧形成大体积空间的第二气流段112，其可以降低雾化气溶胶的流速，减少雾化气溶胶的冷凝；在雾化腔20混合后的大颗粒气熔胶从横截面积较大的第二气流段112直通进入壳体出气通道，雾化烟油流动的距离较小，吸阻变小，用户抽吸更加方便，在调节电子烟雾化组件吸阻的同时满足用户的抽吸体验。
参照图4所示，在一个实施例中，进一步地，所述壳体1内设置有敞口管件113，所述敞口管件113具有开口部，所述开口部抵接在所述壳体1的内侧壁上，且所述敞口管件113与所述壳体1的内侧壁围合形成所述第二气流段112。
在该具体的例子中，第二气流段112由一个具有开口部的敞口管件113与壳体1的内侧壁直接抵接围合而成，这样提高了壳体1内的空间利用率，第二气流段112的形成非常方便。进一步具体地，第二气流段112的截面可以呈U型结构，当然，其还可以呈C型、弧形、半圆形和V字形中的一种。
参照图5所示，在一个实施例中，进一步地，所述雾化芯组件包括多孔体31，所述多孔体31沿第一方向的一侧设置有第一凹口部311，所述第一凹口部311由多孔体31第一方向的一边缘朝向另一边缘凹陷形成，所述第一凹口部311与敞口管件113匹配连接，并且所述第一凹口部311与所述壳体1的内侧壁围合形成通孔部，所述通孔部与所述第二气流段112联通，以使所述雾化腔20与所述出气通道11连通。
在该具体的例子中，多孔体31一侧凹陷形成的第一凹口部311的形状与敞口管件113相匹配，第一凹口部311和敞口管件113配合连接；该多孔体31在宽度方向上尺寸减小，提高了空间利用率，使得雾化芯组件的结构设计适配性更强。进一步地，参照图5所示，所述第一方向a为所述多孔体31的 短轴方向，也就是所述多孔体31的宽度方向。第一凹口部311与壳体1的内壁围合形成气流通道，雾化腔20通过该气流通道与出气通道11连通。
参照图6所示，在一个实施例中，进一步地，所述雾化芯组件包括雾化芯密封件4，所述雾化芯密封件4包括本体部41，所述本体部41沿第一方向的一侧设置有第二凹口部411，所述第二凹口部411由本体部41第一方向的一边缘朝向另一边缘凹陷形成，所述第二凹口部411在所述第一凹口部311与所述敞口管件113之间形成密封连接。
在该具体的例子中，雾化芯密封件4的本体部41具有适配第一凹口部311的第二凹口部411，第二凹口部411在第一凹口部311与敞口管件113之间起到了密封连接的作用，以提高雾化芯组件与壳体的密封性。进一步具体地，本体部41的宽度方向与多孔体31的宽度方向一致。
参照图6所示，在一个实施例中，进一步地，所述本体部41的外侧面在所述第二凹口部411以外的区域设置有第一弹性凸筋43，所述第一弹性凸筋43抵接在壳体1的内侧壁上；所述本体部41的外侧面在与所述第二凹口部411对应的区域设置有第二弹性凸筋44，所述第二弹性凸筋44抵接在所述敞口管件113的外侧壁上。
在该具体的例子中，第一弹性凸筋43和第二弹性凸筋44的设置提高了雾化芯密封件4的密封效果，防止储液腔102内的烟油从雾化芯密封件4和壳体1之间的配合间隙发生漏油。
参照图7所示，在一个实施例中，进一步地，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，这样可以降低用户抽吸时的噪音；进入雾化腔20中的空气气流与发热体组件32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1、图2所示，在一个实施例中，进一步地，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，进一步地，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。
参照图1、图2所示，进一步地，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32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的弹性件42在雾化腔20气压的作用下被顶开，气体通过设置于壳体1内侧壁的换气槽103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，使得雾化芯组件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32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22可以成倍加高，加高后的固定柱22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。
在本公开的又一个实施例中，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。
该电子烟可通过设置于壳体1的内侧壁上的换气槽103实现储液腔和雾化腔的气压平衡，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。
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32之间的电连接导通并向发热体组件32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。
