相关申请的交叉参考
本申请要求于2020年04月10日提交中国专利局，申请号为2020102812822，名称为“雾化器及电子烟”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
本申请实施例涉及电子烟技术领域，尤其涉及一种雾化器及电子烟。
背景技术
电子烟是将含有尼古丁的液体基质加热雾化成气溶胶后，让用户吸食的一种产品。电子烟实现雾化功能的部分为雾化器，其结构包括存储液体基质的储液腔、从储液腔吸取液体基质的多孔体、对多孔体吸取的液体基质进行加热雾化的发热体。进一步为了在抽吸的过程中形成气溶胶的传输，雾化器的外壳上对应发热体的部分设有用于进气的进气孔，以及将气溶胶输出的烟气传输管。用户抽吸的过程中，外部空气从进气孔进入雾化器内、再携带气溶胶通过烟气传输管输出，形成完整的气流循环。
由于气流循环结构的设置，雾化器使用过程中从多孔体上渗出的液体基质、以及加热形成的气溶胶传输中受冷后形成的冷凝液，在雾化器内部积累之后，会从进气孔流出，从而造成漏油和污染。
基于以上内容，作为改进的现有技术201820119392.7号专利中提出了一种具有对进气孔遮挡结构的雾化器，采用能在雾化器轴向的平面上的能投影覆盖进气孔的挡片，从而对进气孔进行遮挡，从而防止液体基质流出。增加挡片结构后，一方面造成吸阻增加，另一方面由进气孔进入的外部气流变得扩散，使得生成的气溶胶一部分被扩散至边角落部位而滞留，降低了出烟效率。

具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
本申请实施例提出一种用于对液体基质加热雾化类型的电子烟产品。在一个实施例中以通常的图1和图2所示扁烟为例进行举例说明，包括用于对液体基质进行雾化的雾化器100，以及为雾化器100供电的电源装置200。其中，电源装置200上还分别设置有用于与雾化器100对应连接导电的导电弹针210；以及与雾化器100上的磁吸元件对应磁 吸的磁体220。
雾化器100的详细的结构可以参见图3的分解示意图和图4的剖面示意图所示，包括：
中空的筒状外壳体10，该外壳体10具有沿轴向方向相对的近端和远端；其中，根据通常使用的需求，近端被配置为作为用户吸食气溶胶的一端，远端被作为与电源装置200进行装配连接的一端；为了便于描述，外壳体10还具有沿厚度方向相对的第一侧壁110和第二侧壁120。
基于以上使用的不同，外壳体10的近端上设置有吸烟口A，用于供用户进行抽吸操作；外壳体10的远端为敞口设计，其上安装有可以拆卸的端盖20，远端的敞口结构用于向外壳体10内部安装各必要功能部件。
在一些实施例中，所述外壳体靠近所述第一侧壁设置有第一连通口(未标示)，所述第一连通口便于外界空气进入雾化器内部。
在一些实施例中，所述外壳体靠近所述第二侧壁设置有第二连通口(未标示)，所述第二连通口便于雾化器内部气体流出雾化器。
进一步外壳体10的内部设置有用于存储液体基质的储液腔30，以及用于从储液腔30中吸取液体基质并进行加热雾化的雾化组件40；具体的，在图4所示的剖面结构示意图中，外壳体10内设有沿轴向设置的烟气传输管11，该烟气传输管11的外壁与外壳体10内壁之间的空间形成用于存储液体基质的储液腔30；该烟气传输管11相对近端的第一端与吸烟口A连通、相对远端的第二端与雾化组件40连接，从而将雾化组件40雾化液体基质生成的气溶胶传输至吸烟口A处吸食。
参见图3所示的雾化组件40结构，其可包括用于从储液腔30吸取液体基质的多孔体41、以及用于对该多孔体41中吸取的液体基质进行加热雾化的加热元件42。如图3所示，该多孔体41在实施例中可大致呈但不限于块状结构，根据使用的情形，其包括沿外壳体10的轴向方向相背的吸液面411和雾化面412，即为图3中块状多孔体41的上、下表面，其中，雾化面412从所述第一侧壁110延伸至第二侧壁120而得到；此外，吸液面411与储液腔30相对，通过直接或间接与储液腔30中的液体基质相接触，从而吸取液体基质；多孔体41内部所具有的多孔结构再将液体基质传导至雾化面412受热雾化形成气溶胶，并从雾化面412释放逸出。在图3所示的多孔体41结构上，由于吸液面411与雾化面412相互平行，液体基质和气溶胶在多孔体41中的移动方向均与雾化面412所在的平面相垂直。气溶胶和液体基质在多孔体41内的移动将更加流畅，且制造比较方便。
在一些实施方式中，多孔体41可由多孔陶瓷、多孔玻璃陶瓷、多孔玻璃等硬质毛细结构制成。加热元件42优选采用通过具有导电性的原材料粉末与印刷助剂混合成浆料后于印刷后烧结的方式形成在雾化面412上，从而使其全部或绝大部分表面都与雾化面412紧密结合，具有雾化效率高、热量损失少、防干烧或大大的减少干烧等效果。该加热元件42在一些实施例中可采用不锈钢、镍铬合金、铁铬铝合金、金属钛等材质。
进一步参见图2至图4，为了便于对雾化组件40的安装固定、以及对储液腔30进行密封，在外壳体10内还设有密封机构50，密封机构50包括硅胶套51、刚性的支撑套52和硅胶座53，既对储液腔30的端口进行密封，还将雾化组件40固定保持在内部。其中，
硅胶套51的结构和形状不作限定，在一些实施例中，硅胶套51大体呈环状，内部中空511用于容纳雾化组件40，并通过柔性紧配的方式套设在雾化组件40外。
支撑套52则对套设有硅胶套51的雾化组件40进行支撑保护，在一些实施例中，支撑套52可包括大致呈椭圆柱状的主体部521、由主体部521的底面向下延伸的夹持壁522，该夹持壁522呈C型形状，从而在夹持壁522内形成用于容纳并保持硅胶套51和雾化组件40的保持腔523。支撑套52与外壳体10的第一侧壁110相对的一侧设置有气流通道524，用于将雾化面412产生的气溶胶输出；支撑套52上形成有第一导液孔525，用于向吸液面411传递液体基质。
在一些实施例中，所述气流通道524的至少一部分设置于所述密封机构上。
硅胶座53设置于储液腔30朝远端的端部，且其外形与外壳体10内轮廓的横截面适配，从而对储液腔30实现密封防止液体基质从储液腔30漏出。进一步为了防止柔性材质的硅胶座53的收缩变形影响密封的紧密型，则通过以上刚性支撑套52容纳在硅胶座53内对其提供支撑。配合的结构上，硅胶座53具有由底面向下延伸出的两个相对的第二夹持壁531，并在两个第二夹持壁531之间形成用于容纳支撑套52的主体部521的容纳腔532。同时硅胶座53上形成有两个第二导液孔533以及一个气管插接孔534；其中两个第二导液孔533与支撑套52上的两个第一导液孔525对应，从而使储液腔30内的液体基质能经过第二导液孔533、以及第一导液孔525后流动至多孔体41的吸液面411被吸收；气管插接孔534则用于供烟气传输管11的下端插接，同时在安装后烟气传输管11与气流通道524是气流连通的，从而将生成的气溶胶输出至 吸烟口A。
进一步，为了使密封机构50在雾化器100内稳定固定，端盖20具有立于该盖体21顶面的两个第一支撑臂21，用对密封机构50进行支撑。
同时，端盖20上设置有第一安装孔22、第二安装孔23、以及进气孔24。其中，第一安装孔22内安装可与电源装置200的磁体220磁性吸附的磁性元件25，比如磁铁或铁磁材质的元件；第二安装孔23内用于安装电极柱26，用于与电源装置200的导电弹针210连接之后，作为供电的电极向加热元件42供电。进气孔24用于在抽吸过程中供外部空气进入雾化器10内。
使用中的，可以参见图4中箭头R1所示，液体基质从储液腔30内经第二导液孔533与第一导液孔525后进入至硅胶套51的环状空间内并由多孔体41的吸液面411吸收，并传递到雾化面412被加热元件42加热雾化形成气溶胶释放。
进一步为了使气溶胶的释放和传递能更加顺畅，参见图3和图4所示，端盖20与雾化面412之间设置有承接座60；该承接座60与雾化面412之间保持有一定的间距用于形成供气溶胶释放的雾化腔70。
进一步参见图3和图7所示，进气孔24被构造成是靠近外壳体10的第二侧壁120的位置设置，从而与气流通道524是分别处于雾化腔70的两侧的，则进一步在抽吸的气流方向上可以参见图3、图5和图7所示，进气孔24进入的空气由靠近第二侧壁120的位置进入至雾化腔70，而后沿外壳体10的厚度方向贯穿雾化腔70后从靠近第一侧壁110的气流通道524输出至烟气传输管11。使用户抽吸时气流能穿过整个雾化腔70，从而使雾化腔70内的气溶胶能最大化地随着气流导出减少滞留，从而提升出烟效率、以及防止雾化腔70内生成冷凝液。
在一些实施例中，所述进气孔24与所述第一连通口连通，便于外界空气进入雾化腔内。
在一些实施例中，所述气流通道524与所述第二连通口连通，便于雾化腔70内的气体流出。
进一步参见图5、图6和图7所示，承接座60大体呈块状，并具有相对的第一表面61和第二表面62，其中第一表面61与雾化面412是相对的并保持有间距从而形成雾化腔70。在设计中，该第一表面61是倾斜的，具体是沿着靠近第一侧壁110的方向向上倾斜的。作用一方面是用于通过倾斜的设计引导气流，如图6中箭头R2所示气流在第一表面61的引导下倾斜的流出；另一方面雾化腔70中气溶胶遇冷空气后冷凝形成的冷凝液、以及从雾化组件40向下渗漏出的液体基质，能被第一 表面61所承接并在倾斜的第一表面61的引导下沿图6中箭头R3的方向逐步流动由承接座60的引流侧壁64掉落。
进一步承接座60上还设置有雾化器100的长度方向贯穿的通孔63，用于供电极柱26通过该通孔63后与雾化面412上的加热元件42的两端抵靠导电。
在图7所示的优选实施中，由承接座60上流下的冷凝液会逐步流向第二表面62与端盖20之间的间隙中，而进气孔24位于端盖20内的端口的高度是介于的倾斜的第一表面61的最高处和最低处之间的，从而由进气孔24的端口流出的空气是朝着第一表面61的某个中间部位的，使得第一表面61能至少部分地对穿过雾化腔70的气流进行引导。
进一步为了避免由承接座60滴向端盖20的冷凝液从端盖20的第一安装孔22和第二安装孔23渗出。图8示出了又一个优选的实施的承接座60的示意图，在与端盖20相对的第二表面62a上设置有若干沟槽621a，通过沟槽621a可以利用毛细原理吸附和保持冷凝液，进一步防止冷凝液或承接的液体基质渗出。从图8还可以看出，沟槽621a是沿着雾化器100的厚度方向延伸的，即与气流穿过雾化腔70的方向是平行的，从而在气流流动的流体力促进吸附。在其他的可变实施中，这些沟槽621a也可以使弯折的、交叉等方式布置的。或者在其他的可变实施中，沟槽621a也可以替换成其他能通过毛细作用吸附冷凝液或液体基质的毛细结构，比如具有毛细孔隙或者凹凸的结构。
或者在又一个优选的实施中，参见图9所示，承接座60b是由两个部件组合而成，具体包括：
壳体610b和吸液部件620b，壳体610b具有相对的第一表面61b第二表面62b；其中第一表面61b是倾斜的弧面用于引导气流和承接冷凝液，壳体610b内具有位于第二表面62b的敞口的腔室，用于吸附和保持冷凝液的吸液部件620b设置于该腔室内；该吸液部件620b比如采用海绵、多孔陶瓷或者泡沫材质或者具有能通过毛细作用吸收液体的材料制备，从而当承接的冷凝液从引流侧壁64b流落至与端盖20之间的间隙时能被吸液部件620b露出于壳体610b敞口的表面吸收，从而消除冷凝液或液体基质的渗漏。
在一些实施例中，吸液部件620b的至少一部分表面裸露于壳体610b外并形成第二表面62b。
在一些实施例中，所述第一表面的至少一部分与第一连通口沿雾化面的延伸方向相对。
进一步在优选的实施中，以上承接座60的第一表面61沿垂直于外 壳体轴向平面上的投影面至少一部分覆盖雾化面。优选的，沿雾化器100的轴向方向上的投影面大于雾化面412，并且是完全覆盖雾化面412的。同时从图5和图7可以看出，端盖20形成进气孔24的结构部分沿雾化器100的厚度方向与承接座60的引流侧壁64是不接触并保持有一定的间距的，大约5mm左右，进而使得冷凝液能顺畅地通过承接座60的引流侧壁64从第一表面61导引至第二表面62吸收。
以上电子烟雾化器，由雾化面与承接座之间形成雾化腔，并且在抽吸过程中气流是穿过整个雾化腔，从而使雾化腔内的气溶胶能最大化地随着气流导出减少滞留；并且承接座能承接并引导冷凝液至第二表面，从而可以有效防止冷凝液随着气流被抽吸或者渗出。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但并不限于本说明书所描述的实施例，进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
