电子雾化吸入器的雾化嘴 技术领域
本发明涉及将具有味道的液体雾化从而供使用者吸入的电子雾化装置， 特别涉及该电子雾化器的雾化说嘴的结构改进。
背景技术
吸入式电子雾化器， 一般用于模拟吸烟物品或用于治疗呼吸道疾病 的吸入药剂的吸入器。 它一般具有容纳有电书源和控制***的杆体部， 与杆体 部连接的液体雾化部和吸嘴部。 在现有技术中， 有将所述液体雾化部与所述 吸嘴部分开设置而插接或粘结在一起的结构， 也有将它们合并为一的结构。
比较典型的现有技术结构， 如中国专利 ZL200420031182. 0， 名称为 "雾 化电子烟"所披露的结构， 包括壳体 14及吸嘴 15， 壳体 14的外壁上开有进 气孔 4， 壳体 14内依次设有电子线路板 3、 常压腔 5、 传感器 6、 气液分离器 7、 雾化器 9、 供液瓶 11， 供液瓶 11内设置有贮液多孔体 28; 雾化器 9通过 凸起 36与供液瓶 11相接触， 在雾化器 9的内部设有雾化腔 10; 供液瓶 11的 一侧与壳体 14之间设有锁定供液瓶 11的挡圈 13，供液瓶 11的另一侧开有雾 汽通道 12; 进气孔 4、 常压腔 5、 气液分离器 7、 雾化器 9、 雾汽通道 12、 导 气孔 17、吸嘴 15依次相连通。虽然该结构的电子烟产品已经在其现有技术所 采用的超声雾化、 机械式雾化等基础上作出了大的改进， 其雾化器 9 利用液 体的毛细现象， 采用陶瓷等作为雾化腔 10并通过泡沬金属吸纳供液瓶 11 中 的液体使其在陶瓷雾化腔 10内高温雾化， 在雾化气体通道 12上设置气液分 离器 7。 该种结构的产品， 不仅其雾化器 9的结构复杂而且制造成本高， 各个 主要功能构件的装配过程也比较困难， 并且其供液瓶 11内设置有贮液多孔体 28使其能够贮存的液体比较少。 另一款比较典型的现有技术的结构， 如中国专利 ZL200720057873. 1， 名 称为 "一种非可燃性喷雾电子香烟"所披露的结构， 包括有控制器与发生器， 所述控制组件内依次设有指示灯盖、 电源装置、 集成线路板、 微型气体传动 开关和连接导体， 所述发生器内依次设有连接导体、 次级气压保压室、 阻液 片、 次级贮液室、 加热器、 导液机构、 贮液室和吸嘴， 所述连接导体一侧上 开有进气孔， 所述控制器与发生器的连接导体中间开有通孔。 该结构的电子 香烟在现有技术的基础上改进了雾化器的结构， 但是该结构的雾化器与上述 ZL200420031182. 0技术方案一样， 其加热丝设置在导液机构内部， 不仅导液 机构必须使用比较硬的材料制造而且其安装时容易塌陷； 其次其导液机构将 液体传导至次级贮液室使密封比较困难； 另外其贮液室使用药用棉纤维使其 能够贮存的液体比较少。
还有一款比较典型的现有技术的结构， 如中 国专利 ZL200820124683. 1 , 名称为 "一次性一体式电子雾化吸入器"所披露的结构， 包括有包括一杆体； 所述的杆体内部自下向上依次设置有； 一端子， 其与所 述的杆体内壁相结合， 用以与一电子烟杆相连接； 一端子芯， 其设置于所述 的端子上， 用以与所述的电子烟杆的电极电连接； 一雾化器， 其与所述的端 子芯电连接， 所述的雾化器内部设置有通气孔， 用以通电加热产生雾化现象; 一电子雾化吸入器嵌件， 其位于所述的雾化器上端， 其内部通过储液媒介吸 附或储存将被雾化的烟液； 一电子雾化吸入器上盖， 其嵌入所述的杆体上端， 所述的电子雾化吸入器上盖具有一通气孔， 用以密封并防止烟液回流。 该结 构的电子雾化吸入器在其说明书中并未详细地披露烟液被传到通气孔的路 径， 也未说明加热器如何雾化烟液的过程； 其次根据该技术方案说明书附图， 可以看出其电子雾化吸入器嵌件的一端为完全敞开的结构， 电子雾化吸入器 嵌件内的烟液完全靠储液媒介吸附， 这样不仅储液媒介本身吸附的烟液就比 较少， 而且在其稍微吸附多一点时就非常容易形成液滴跌落到其雾化器 5 的 骨架上并沉积到雾化器 5的底部， 从而在其雾化器 5具有储热功能和均热功 能的情况下就会烧焦烟液， 沉积在雾化器 5底部的烟液也不能容易地从通气 通道中排出。 发明内容
针对电子雾化类产品， 目前在电子控制技术已经相对比较成熟稳定的情况下， 发明结构简单、 装配容易， 使用方便和安全的电子雾化器产品， 进一步改进 雾化嘴的结构是非常重要的环节。 为此能使吸食者轻松吸食， 又能使雾化嘴 结构更加简单从而使装配、 存储和使用方便安全， 还能尽可能地提高雾化液 体的数量是本设计企求解决的主要问题之一。 为此， 在现有技术基础上， 提 出如下设计方案： 电子雾化吸入器的雾化嘴， 包括呈筒状的外壳体， 所述外 壳体的前端筒口部设置封堵壁， 所述封堵壁上设置有出气孔； 所述外壳体的 后端筒口部设置有后端封堵器， 所述后端封堵器上设置有进气孔； 所述外壳 体、 封堵壁和后端封堵器所形成的容纳腔内设置有液体容器和加热器， 所述 外壳体与所述液体容器之间具有与所述出气孔连通的空气流通通道； 其特征 在于， 还包括导液器， 所述导液器堵封在所述液体容器的开口部， 所述液体 容器内没有贮液介质， 所述导液器与所述后端封堵器之间具有连通所述空气 流通通道与所述进气孔的连通通道； 所述加热器设置在所述后端封堵器的顶 端部并接触所述导液器的下表面， 至少部分所述加热器位于所述连通通道中。
所述电子雾化器， 是可以将其内的液体予以雾化从而可以供消费者吸食 雾化气体的器具， 至少包括有雾化嘴部件和控制电源部分， 所述雾化嘴部件 和控制电源部分之间可以通过螺紋电极连接； 其中所述控制电源部分给所述 雾化嘴内的加热器提供电能， 所述加热器将所述雾化嘴内的液体予以雾化供 使用者吸食。 所述雾化嘴内设置有液体容器和加热器部件， 由于所述外壳体、 封堵壁和后端封堵器组合形成容纳腔， 而且所述液体容器、 导液器和加热器 容纳在所述容纳腔内， 为此所述雾化嘴可以作为一个独立的部件制造和装配。 在使用中， 还可以将所述雾化嘴作为一次性使用的配件， 即在所述雾化嘴内 的液体使用完毕后， 就整个更换所述雾化嘴， 从而使所述雾化嘴更换方便、 使用安全。 其中使用者从所述封堵壁部位进行吸食， 抽吸所述雾化嘴内被雾 化的汽体。
所述外壳体的前端筒口部设置的封堵壁， 可以是仅仅封堵在所述外壳体 的前端筒口部的壁体， 也可以是一个呈帽状的盖子以插接、 螺紋或粘结等方 式盖封在所述外壳体的前端筒口部； 在所述封堵壁上设置出气孔从而便利于 被雾化的汽体从中溢出， 进而可以让使用者利用该出气孔吸食所述雾化嘴内 被雾化汽体。
所述后端封堵器首先是一个可以封堵所述外壳体的后端筒口部的部件， 从而与所述外壳体和所述封堵壁一起形成容纳腔； 其次所述后端封堵器还可 以支撑所述加热器并将所述加热器顶抵在所述导液器的下表面； 另外还可以 利用所述后端封堵器的顶端部顶抵所述导液器， 防止所述导液器从所述液体 容器的开口部脱落。 所述后端封堵器的尾端部与所述外壳体的内侧之间可以 设置密封圈， 防止滴落到所述后端封堵器上的液体爬行到所述外壳体的外面， 其次设置所述密封圈后， 所述后端封堵器与所述外壳体之间还可以非常便利 地以插接的方式予以装配， 而且当所述外壳体出现热胀冷缩问题时， 所述密 封圈可以自动地适应所述后端封堵器与所述外壳体之间的不同间隙， 使其密 封状态良好。
另外， 为了便利于制造所述后端封堵器， 还可以将所述后端封堵器分为 加热器固定座和密封座两个部件制造， 其中所述加热器和所述进气口设置在 所述加热器固定座上， 而所述密封圈设置在所述密封座与所述外壳体之间并 固定连接， 所述密封座支撑所述加热器固定座。 这样所述加热器固定座可以 用耐高温的材料如陶瓷、 硅橡胶等制造， 而所述密封座可以采用普通的金属 或非金属材料制造， 从而可以充分地发挥所述加热器固定座的耐高温性能， 又能发挥所述密封座的连接性能， 同时又能简化制造模具本身的结构。 另外 由于所述加热器固定座与所述加热器直接接触， 所述加热器固定座可以蓄存 一部分所述加热器所述发出的热量， 这样即使在所述加热器停止加热时也能 使所述连通通道内的空气及所述连通通道上面的部分所述导液器内的液体温 度维持在比较高的程度， 从而有利于对所述连通通道内的液滴予以雾化， 也 有利于所述导液器内的液体渗透出来并雾化。
所述液体容器是一个具有容腔的瓶状体， 其具有开口部， 所述液体容器 内的液体可以从所述开口部溢出； 在产品使用前或装配前可以在所述液体容 器内灌装被雾化的液体。 所述液体容器可以与所述外壳体一体化制造， 也可 以分开制造， 其次所述液体容器的开口部可以是束口型的也可以是敞开型的 形状。
在所述液体容器的开口部为束口型的情况下， 所述液体容器的顶端可以 直接***所述导液器中， 或者在所述液体容器是可拆卸的情况下， 可以设置 下述的垫片并穿过下述的垫片后再***所述导液器中， 当然也可以采用将全 部或部分所述导液器嵌入所述液体容器的开口部， 但无论如何都应当使所述 液体容器内的液体只能慢慢地渗透出来。
当所述液体容器的开口部为敞口形状时， 可以在所述液体容器的开口部 内侧设置定位台阶， 通过一个设置在所述定位台阶上的垫片预堵封住所述液 体容器的开口部， 在所述垫片上设置导液孔， 再在所述垫片的下面设置所述 导液器。 这样所述垫片和所述导液器可以共同封堵所述液体容器的开口部， 而所述导液孔则慢慢地将所述液体容器内液体导出到所述导液器。 其次所述 垫片也可以对所述导液器的装配深度予以限位， 防止在装配所述导液器时， 所述导液器过分地陷入所述液体容器太深， 其次还可以在所述后端封堵器顶 压所述导液器时， 防止所述导液器过多地向所述液体容器内移动。
所述导液器堵封在所述液体容器的开口部， 是指所述导液器仅仅位于所 述液体容器的开口部的内侧或开口部的开口处， 这样所述导液器不仅可以防 止液体直接从所述液体容器的开口部直接流出， 其次还可以吸收所述液体容 器内的液体， 使所述液体容器内被雾化液体以不断渗透的方式进入所述导液 器。 由于所述导液器仅仅位于所述液体容器的开口部的内侧或开口部的开口 处， 而不是设置在所述液体容器的主要贮液内腔空间内， 也即所述液体容器 内没有贮液介质； 为了防止所述导液器与所述液体容器的开口部之间密封不 严或出现松脱间隙， 最好是至少有部分所述导液器直接嵌入所述液体容器的 开口部的内侧。 所述导液器可以是纤维棉、 海绵等耐高温的无毒多孔并具有 弹性的材料制造。
为了使所述液体容器内被雾化液体容易渗透出来， 进一步的技术方案是， 还可以在所述液体容器内设置通气管， 所述通气管的一端插接在所述导液器 中， 另一端延伸到所述液体容器的上部。 这样所述液体容器外的空气可以沿 所述通气管慢慢穿透到所述液体容器内使所述液体容器内不至于出现过分的 负压。 所述通气管的一端最好不要穿透所述导液器， 这样可以利用一部分所 述导液器的壁体形成对所述通气管的半密封， 即气体可以慢慢地渗透到所述 通气管中。
所述连通通道是设置在所述导液器与所述后端封堵器之间的气流通道， 外部空气从所述进气口进入所述雾化嘴内后， 经过所述连通通道后在进入所 述外壳体与所述液体容器之间的所述空气流通通道， 这样被加热雾化的液体 就可以沿着所述空气流通通道溢出。
形成所述连通通道的方式有很多种， 其中之一是在所述后端封堵器 （或 所述加热器固定座） 的顶端部中央预留出一个凹陷腔， 所述进气口与所述凹 陷腔连通， 所述加热器跨接在所述凹陷腔的周围侧壁体上， 在所述凹陷腔的 侧壁上设置通孔， 这样所述后端封堵器的顶端部周边的侧壁体可以将所述加 热器顶抵在所述导液器的下面， 而所述凹陷腔成为所述连通通道 （也即雾化 腔）， 被雾化的液体 （汽体） 穿过所述凹陷腔侧壁上的通孔进入所述外壳体与 所述液体容器之间的所述空气流通通道。 另一种形成所述连通通道的等同方 式是， 在所述后端封堵器 （或所述加热器固定座） 的顶端部设置凸出的凸出 柱， 所述加热器架设在所述凸出柱上， 所述凸出柱的***空间就形成所述连 通通道 （也即雾化腔）。 其次还可以是上述两种方案的结合使用。 由于利用所 述凹陷腔侧壁或所述凸出柱与所述导液器的结合自然地形成所述连通通道， 这样在装配所述后端封堵器 （或所述加热器固定座） 顶抵到所述导液器时， 不会出现所述连通通道变形堵塞等问题， 也能确保所述加热器不仅位于所述 连通通道中而且被顶抵在所述导液器的下面。
所述加热器是可以将液体加热并予以雾化的部件， 它位于所述后端封堵 器的顶端部， 这样可以使其尽可能地多接触所述导液器， 这样所述加热器本 身就可以吸附所述导液器上的液体； 其次， 由于至少部分所述加热器位于所 述连通通道内， 这样扩散到所述连通通道内和所述加热器上的液滴就可以借 助于所述加热器予以雾化并被流动的空气带走到所述外壳体与所述液体容器 之间的所述空气流通通道。 为了使所述导液器上的液体容易扩散， 还可以将 所述加热器绕制在耐温纤维芯上， 这样可以进一步借助于所述耐温纤维芯接 触或接近所述导液器的特点， 进一步吸附从所述导液器上和所述加热器扩散 出来的液滴， 使比较多的液滴容易被所述加热器加热雾化。 另一种方案还可 以是， 在所述导液器的下表面设置扩散垫， 所述加热器接触所述扩散垫的下 表面。 这样可以借助于所述扩散垫将所述导液器上的液体予以更加均匀地扩 散； 所述扩散垫是一种片状材料， 其贮液性能可以比所述导液器差但其扩散 性能比较好， 所述扩散垫可以黏贴在所述导液器的下表面。 所述加热器的电 极引线穿过所述后端封堵器后与外部电源连接。
至少部分所述加热器位于所述连通通道内， 是指由于所述加热器架设在 所述后端封堵器的顶端部， 而且也与所述导液器或所述扩散垫的下表面接触， 为此所述加热器的外表面不可能全部暴露在所述连通通道中。
为了便于装配和使用所述加热器， 进一步的技术方案还可以是， 在所述 后端封堵器的上端部设置与所述加热器适配的半圆形凹槽， 所述加热器架设 在所述半圆形凹槽内。 这样可以在所述后端封堵器的顶端部的支撑下使所述 加热器与所述导液器或扩散垫的下表面形成良好的接触， 但又能够保证所述 加热器位于所述连通通道中。
根据上述技术方案， 在所述液体容器内灌装被雾化的液体介质， 并且将 所述液体容器定位在所述外壳体内， 然后用所述导液器将所述液体容器的开 口部予以堵封， 再后将设置有所述加热器的所述后端封堵器固连在所述外壳 体的后端筒口部， 并使所述后端封堵器 （或加热器固定座） 的顶端部顶抵在 所述导液器的下面， 并使所述后端封堵器 （或加热器固定座） 的顶端部与所 述导液器之间具有所述连通通道， 这样所述液体容器中液体可以通过所述导 液器或设置在所述导液器下表面的所述扩散垫向所述连通通道扩散， 所述加 热器加热时， 流动的空气就可以将被雾化的汽体带出。
上述方案不仅结构简单， 装配容易而且密封效果好， 而且还具有如下主 要的有益效果：
( 1 ) 由于所述加热器设置在所述后端封堵器的顶端部并且接触所述导液 器或位于其下面所述扩散垫的下表面， 这样利用液体本身所具有的爬行能力 以及液体本身的重力作用， 使所述加热器本身或其中心的纤维芯就可以比较 容易吸附液体；
( 2 ) 由于在所述液体容器内没有设置任何贮液的介质， 从而在同样体积 的情况下相对大大提高了每一只电子雾化吸入器的雾化嘴的贮液数量， 从而 使产品更加经久耐用， 改变了传统产品必须使用贮液介质的缺陷；
( 3 )所述导液器堵封在所述液体容器的开口部， 可以充分利用负压原理 及液体本身的粘性实现对所述液体容器内的液体密封但又可以导出所述液体 容器内的液体；
(4 ) 在所述后端封堵器 （或所述加热器固定座） 的顶端部设置凸出的凸 出柱， 所述加热器架设在所述凸出柱上， 从而所述凸出柱的***空间就形成 所述连通通道， 这样在装配所述后端封堵器 （或所述加热器固定座） 顶抵到 所述导液器时， 不会出现所述连通通道变形堵塞等问题， 也能确保所述加热 器位于所述连通通道中。
为此， 由于本发明具有上述特点和优点， 可以应用在电子雾化吸入器产品 中。 附图说明

下面结合附图对应用本发明技术方案的电子雾化吸入器的雾化嘴的结构作 出具体说明。
如图 1 所示， 一种电子雾化吸入器， 是可以将其内的液体予以雾化从而 可以供消费者吸食雾化气体的器具， 包括雾化嘴 1和电源控制部分 2， 两者都 呈杆状， 所述雾化嘴 1和控制电源部分 2之间通过螺紋电极 50实现电连接和 机械连接。 其中所述电源控制部分 2包含有电源、 控制电路等并且所述控制 电源部分 2给所述雾化嘴 1提供电能； 所述电源控制部分 2与所述雾化嘴 1 之间通过螺紋电极可拆卸地连接起来。 如图 2、 图 3和图 4所示， 电子雾化吸入器的雾化嘴 1包括呈筒状的外壳 体 3。
所述外壳体 3的前端筒口部设置封堵壁 4，所述封堵壁 4上设置有出气孔 41； 其中所述封堵壁 4呈帽状并插接在所述外壳体 3的前端筒口部的壁体上。 在所述封堵壁 4上设置出气孔 41从而便利于被雾化的汽体从中溢出， 进而可 以让使用者利用该出气孔 41吸食所述雾化嘴 1内被雾化汽体。
所述外壳体 3的后端筒口部设置有后端封堵器 5，所述后端封堵器 5上设 置有进气孔 51 ; 其中所述后端封堵器 5包括加热器固定座 52和密封座 53两 个部件， 所述进气口 51设置在所述加热器固定座 52上； 在所述密封座 53的 中间横隔上也设置比较大的中央孔 530，所述中央孔 530实际上也是所述进气 口 51的进气通道。
所述加热器固定座 52的顶端部设置两个凸出柱 521， 在所述凸出柱 521 的顶端部设置呈半圆形的凹槽 522， 所述加热器 Ί架设在两个所述凸出柱 521 之间并位于所述凹槽 522内。 所述加热器 7的两个电极引线 70穿过所述加热 器固定座 52后通过所述螺紋电极 50电连接所述电源控制部分 2 ;其中所述密 封座 53的尾端外侧设置连接螺紋并形成所述螺紋电极 50的一个电极， 所述 螺紋电极 50的另一个电极在图中未画出。 所述密封座 53呈中空的柱状， 其 外侧通过密封圈 8与所述外壳体 3的后端筒口部固连。 所述密封座 53的内腔 中设置有台阶， 所述台阶的中央部位是所述中央孔 530， 从而所述加热器固定 座 52借助于该台阶被固定在所述密封座 53的内腔的上部腔体中。 所述加热 器固定座 52用耐高温的硅胶制作从而使所述加热器固定座 52具有一定的弹 性， 这样不仅所述加热器固定座 52与所述密封座 53的内腔壁之间能够形成 比较好的密封效果， 也能在所述加热器固定座 52顶抵所述导液器 9的下表面 时具有一定的弹性， 使所述加热器 7更加贴合在所述导液器 9的下表面。
如图 2、 图 3和图 4所示， 所述外壳体 3、 封堵壁 4和后端封堵器 5所形 成的容纳腔内还设置有液体容器 6，在所述后端封堵器 5与所述液体容器 6之 间设置所述加热器 7和所述导液器 9。
所述液体容器 6 是一个具有容腔的瓶状体， 其开口部呈敞口型， 即其开 口部的内径至少等于所述液体容器 6的内部腔体的内径； 所述液体容器 6内 没有设置任何贮液的介质。 在产品使用前或装配前可以在所述液体容器 6 内 灌装被雾化的液体 60。 所述液体容器 6与所述外壳体 3分开制造， 从而减少 制造模具的制造难度。
所述导液器 9是一种可以防止液体 60直接从所述液体容器 6的开口部直 接流出的部件， 其次所述导液器 9还可以吸收所述液体容器 6内存贮的液体 60， 使所述液体容器 6内的液体 60以不断渗透的方式进入所述导液器 9。 为 了使所述液体容器 6内的液体 60容易渗透出来， 进一步的技术方案是， 如图 5所示， 还可以在所述液体容器 6内设置通气管 62， 所述通气管 62的一端插 接在所述导液器 9中但并不穿透所述导液器 9的全部壁体， 另一端延伸到所 述液体容器 6的上部。 这样所述液体容器 6外的空气可以沿所述通气管 62慢 慢穿透到所述液体容器 6内使所述液体容器 6内不至于出现过分的负压。 所 述导液器 9是纤维棉， 当然也可以是海绵等耐高温的无毒多孔材料制造。
如图 2和图 4所示， 在所述液体容器 6开口部内侧设置有定位台阶 31， 通过一个设置在所述定位台阶 31上的呈帽状的垫片 32堵封住所述液体容器 6， 并且还在所述垫片 32上设置导液孔 33， 所述导液器 9嵌入所述液体容器 6开口部内侧堵封在所述垫片 32及其所述导液孔 33的后面。 这样所述垫片 32不仅可以预封堵所述液体容器 6的开口部，而所述导液孔 33则慢慢地将所 述液体容器 6内的液体 60导出到所述导液器 9。其次所述垫片 32也可以对所 述导液器 9的嵌入装配深度予以限位， 防止在装配所述导液器 9时， 所述导 液器 9过分地陷入所述液体容器 6太深， 其次还可以在所述后端封堵器 5顶 压所述导液器 9时， 防止所述导液器 9向所述液体容器 6内移动。 所述垫片 32呈帽状， 可以在装配所述垫片 32时容易实现所述垫片 32在所述液体容器 6开口部内侧定位。
如图 5所示， 所述液体容器 6的开口部可以是束口型的形状。 所述导液 器 9直接全部嵌入到所述液体容器 6的开口部。
如图 3和图 4所示， 所述外壳体 3与所述液体容器 6之间具有与所述出 气孔 41和所述进气孔 51连通的空气流通通道 61。所述空气流通通道 61可以 均布在所述液体容器 6的外周， 也可以仅仅只分布在所述液体容器 6的一个 或两个侧面。 在本实施例中， 所述液体容器 6 的一个侧壁呈扁平状从而利用 该扁平的形状与所述外壳体 3之间形成所述空气流通通道 61。
如图 2和图 4所示， 由于所述加热器固定座 52的顶端部设置两个凸出柱 521， 从而在所述凸出柱 521的之间的区域和周边区域存在空间， 该空间形成 可以使气流流通的所述连通通道 71。外部空气从所述进气口 51进入所述雾化 嘴 1内后， 经过所述连通通道 71后再进入所述空气流通通道 61， 这样加热雾 化的液体就可以沿着所述空气流通通道 61和所述出气孔 41溢出。 另一种可 以实施的方案是 （图中未画出）， 在所述加热器固定座 52 顶端部中央预留出 一个凹陷腔， 所述进气口 51与所述凹陷腔连通， 所述加热器 7径向跨接在所 述凹陷腔的的周围侧腔壁的顶端部， 在所述凹陷腔的侧壁上设置通孔， 这样 所述加热器固定座 52顶端部周边的侧壁体可以将所述加热器 7顶抵在所述导 液器 9的下面， 而所述凹陷腔成为所述连通通道 71 (也即雾化腔）， 被雾化的 液体 （汽体） 穿过所述凹陷腔侧壁上的通孔进入所述外壳体 3 与所述液体容 器 6之间的所述空气流通通道 61。
如图 2和图 4所示， 所述加热器 7是可以将液体加热并予以雾化的部件， 它架设在所述加热器固定座 52的所述凸出柱 521的顶端部之间并位于所述凹 槽 522内， 这样可以使其尽可能地多接触所述导液器 9， 所述加热器 7本身就 可以吸附所述导液器 9上的液体， 这样扩散到所述连通通道 71内和所述加热 器 7上的液滴就可以借助于所述加热器 7予以雾化并被流动的空气带走到所 述空气流通通道 61。 为了使所述导液器 9上的液体容易扩散， 还可以将所述 加热器 7绕制在耐温纤维芯 72上，这样可以进一步借助于所述耐温纤维芯 72 吸附从所述导液器 9和所述加热器 7上扩散出来的液滴， 使比较多的液滴容 易被所述加热器 7加热雾化。 另一种方案还可以是 （图中未画出）， 在所述导 液器 9的下表面设置扩散垫， 所述加热器 7接触所述扩散垫的下表面， 这样 可以借助于所述扩散垫将所述导液器 9上的液体予以更加均匀地扩散； 所述 扩散垫是一种片状材料， 其贮液性能可以比所述导液器 9 差但其扩散性能比 较好， 所述扩散垫可以黏贴在所述导液器 9的下表面。
根据上述技术方案， 将所述液体容器 6定位在所述外壳体 3内， 并且在所 述液体容器 6内灌装液体 60， 然后用所述导液器 9和所述垫片 32将所述液体 容器 6的开口部予以堵封， 再后将设置有所述加热器 7的所述后端封堵器 5固 连在所述外壳体 3的后端筒口部， 并使所述后端封堵器 5的顶端部及所述加热 器 7顶抵在所述导液器 9的下面， 所述后端封堵器 5的顶端部与所述导液器 9 之间具有所述连通通道 71， 这样所述液体容器 6中液体 60可以通过所述导液 器 9或设置在所述导液器下表面的所述扩散垫向所述连通通道 71、所述加热器 7和所述耐温纤维芯 72扩散， 所述加热器 7加热时， 流动的空气就可以将被雾 化的汽体带出。
