本申请要求于2020年06月16日提交中国专利局，申请号为202010545792.6，名称为“电子烟雾化器及电子烟”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，尤其涉及一种电子烟雾化器及电子烟。
背景技术
存在有气溶胶提供制品，例如，所谓的电子烟装置。这些装置通常包含烟油，该烟油被加热以使其发生雾化，从而产生可吸入蒸气或气溶胶。该烟油可包含尼古丁和/或芳香剂和/或气溶胶生成物质(例如，甘油)。除了烟油中的芳香剂以外。
已知的电子烟装置通常包括内部具有大量微孔的多孔陶瓷体，用于吸取和传导上述烟油，并在多孔陶瓷体的一表面上设置发热元件，对吸取的烟油进行加热雾化。多孔体内的微孔一方面作为烟油向雾化面浸润流动的通道，另一方面作为储油腔烟油消耗后供空气从外部补充进入储油腔维持储油腔内气压平衡的空气交换通道，使得烟油被加热雾化消耗时会在多孔陶瓷体内产生气泡，而后气泡从吸油面冒出后进入储油腔。
对以上已知的电子烟装置，当随着内部储液腔的烟油消耗时，储液腔内逐渐变为负压状态，从而一定程度上阻止流体传递使烟油减少通过多孔陶瓷体的微孔通道传递至雾化面上汽化。特别地，已知的电子烟装置在连续抽吸使用状态下，储液腔外部的空气难以在短时间内通过多孔陶瓷体的微孔通道进入储液腔内部，从而减缓了烟油传递至雾化面上的速率，供应至发热元件的烟油不足会导致发热元件温度过高，从而使烟 油成分分解挥发生成诸如甲醛等致害的物质。

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和图4的分解示意图、以及图5所示的剖面示意图所示，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，在近端设置有用于供用户抽吸的吸嘴口A；而远端被作为与电源装置200进行装配连接的一端，且外壳体10的远端为敞口，其上安 装有可拆卸的端盖20，便于打开敞口向外壳体10内部安装各功能部件。
进一步参见图3至图5所示，外壳体10的内部设置有用于存储液体基质的储液腔12，以及用于从储液腔12中吸取液体基质的多孔体30、以及对多孔体30吸取的液体基质进行加热汽化的加热元件40；具体，在图5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12；该烟气传输管11相对近端的第一端与吸烟口A连通、相对远端的与加热元件40加热生成的气溶胶气流连接，从而将加热元件40汽化液体基质生成的气溶胶传输至吸嘴口A处吸食。
参见图3至图5所示的多孔体30的结构，该多孔体30的形状被构造成在实施例中可大致呈但不限于块状结构；根据本实施例的优选设计，其包括呈拱形形状，具有沿外壳体10的轴向方向相背的吸液面31和雾化面32，即为图3中块状多孔体30的基部部分的上、下表面；其中，吸液面31与储液腔12相对，通过直接或间接与储液腔12中的液体基质相接触，从而吸取液体基质；多孔体30内部所具有的微孔结构再将液体基质传导至雾化面32受热雾化形成气溶胶，并从雾化面32释放或逸出。在图5所示的多孔体30结构上，由于吸液面31与雾化面32相互平行，液体基质和气溶胶在多孔体30中的移动方向均与雾化面32所在的平面相垂直。气溶胶和液体基质在多孔体30内的移动将更加流畅，且制造比较方便。
进一步为了便于装配和固定，在图3至图5所示的优选实施例中多孔体30还包括支撑部分33。
在一些实施方式中，多孔体30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40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32上，从而使其全部或绝大部分表面都与雾化面32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40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3至图5，为了辅助对多孔体30的安装固定、以及对储液腔12进行密封，在外壳体10内还设有密封机构，密封机构包括柔性硅胶套50、刚性支撑架60和柔性硅胶座70，既对储液腔12的敞口进行密封，还将多孔体30固定保持在内部。其中，
具体结构和形状上，柔性硅胶套50大体呈环状，内部中空用于容纳多孔体30，并通过柔性紧配的方式套设在多孔体30外。
刚性支撑架60则对套设有柔性硅胶套50的多孔体30进行保持，在一些实施例中可包括大致呈下端为敞口的环状形状，内部空间用于容纳并保持柔性硅胶套50和多孔体30。
柔性硅胶座70设置于储液腔12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12实现密封防止液体基质从储液腔12漏出。进一步为了防止柔性材质的柔性硅胶座70的收缩变形影响密封的紧密型，则通过以上刚性支撑架60容纳在柔性硅胶座70内对其提供支撑。
在安装之后，为了保证液体基质的顺畅传递和气溶胶的输出，柔性硅胶座70上设置有供液体基质流通的第一导液通道71、刚性支撑架60上对应设置有第二导液通道61，柔性硅胶套50上设置有第三导液通道51。在使用中液体基质依次经第一导液通道71、第二导液通道61和第三导液通道51流向保持于柔性硅胶套50内的多孔体30的吸液面31上，如图5中箭头R1所示，进而被吸收后传递至雾化面32上汽化。
在抽吸过程中气溶胶的输出结构上，柔性硅胶座70上设置有供烟气传输管11下端插接的第一插孔72，对应刚性支撑架60上设置有第二插孔62，刚性支撑架60上与外壳体10的一侧壁相对的一侧设置有将雾化面32与第二插孔62气流连通的第一气流通道64。在安装之后，参见图6中箭头R2所示，加热元件40生成的气溶胶通过第一气流通道64流向第二插孔62后，经第一插孔72向烟气传输管11输出。
进一步在辅助供电和安装结构上，参见图3至图6所示，端盖20上设置有第一支撑脚21，用于对密封机构进行支撑和固定，当然在实施例中是抵靠在刚性支撑架60的下端表面从而实现对密封机构的支撑的。 端盖20上还设置有第一安装孔22和第二安装孔23；其中，第一安装孔22用于安装与电源装置200上的磁体220磁性吸附的磁吸元件25，第二安装孔23用于安装电极26，电极26通过贯穿该第二安装孔23后抵靠在加热元件40的两端从而实现对加热元件40供电；当然，在雾化器100与电源装置200连接之后，电极26与电源装置200上对应的导电弹针210是连接导电的。同时，在端盖20上还设置有在抽吸的过程中供外部空气进入至雾化器100内的进气孔24，参见图6中见图R2所示，外部空气通过该进气孔24流向雾化面32并携带气溶胶输出。
在实施例中，雾化面32与端盖20之间保持有一定的间距，进而至少部分由雾化面32与端盖20围绕并形成用于供气溶胶逸出的雾化腔室，当然该雾化腔室一方面与端盖20上的进气孔24是气流连通的，用于供外部空气进入至雾化腔室内；另一方面与烟气传输管11是气流连通的，用于将雾化面32上生成并逸出的气溶胶输出。
当储液腔12中随着液体基质的消耗使其内部产生负压真空之后，为了保证液体基质仍能顺畅被多孔体30吸收，在雾化器100内还设置有空气通道。进一步参见图7至图9所示；刚性支撑架60上设置有沿雾化器100的轴向方向贯穿的通孔63，并由该通孔63形成用于向储液腔12内补充外部空气的所述空气通道；在安装之后该通孔63的上端被柔性硅胶座70的第一遮挡部分73遮挡、下端是无遮挡的露出状态，并且下端是通过与端盖20之间的缝隙或设置的通道，与雾化腔室气流连通的。
进一步对第一遮挡部分73厚度和位置进行设计，使其厚度大约在比较薄的0.2mm～0.5mm的厚度尺寸，并且在一些实施例中，第一遮挡部分73与其他的部分具有更薄的厚度，使得第一遮挡部分73更容易产生形变。并且采用柔性硅胶座70的材料硬度可在邵氏硬度A型20A至40A之范围内；使得当储液腔12内负压逐渐变化增大之后，压力通过流体传递使得第一遮挡部分73上端的压力降低，从而其能形成图9所示的向上翘起的形变，于通孔63上端露出部分缝隙，从而供外部空气沿图9中箭头R3所示进入至储液腔12内消除负压。
从图4和图8和图9中可以看出，柔性硅胶座70的第一遮挡部分73的位置是靠近第一导液通道71设置的，从而利用开设第一导液通道71达到使第一遮挡部分73的抗弯强度降低的效果，使得第一遮挡部分73更加容易产生形变。或者，还可以另外增加开设若干围绕第一遮挡部分73的若干通孔、槽、缺口、凹陷等具有降低第一遮挡部分73抗弯强度使其更加易于翘起或者形变的减强结构74b/741b，如图14所示。
在不同于第一遮挡部分73紧贴着通孔63端口的表面遮挡的方式外；进一步参见图7至图9所示，刚性支撑架60上设置有第一凹陷结构65，第一凹陷结构65内还设置有与第二插孔62相对的通孔651，该通孔651是与第二插孔62气流连通进而与进气孔24乃至外部空气是气流连通的；因此后续可以通过该通孔651来向储液腔12中进气消除储液腔12的负压；为了辅助通孔651与储液腔12的气流连通，支撑架60上设置有通气槽66，是由第一凹陷结构65延伸至与第二导液通道62，是用于供烟气传输管11的空气进入至储液腔12的空气通道。
对应在柔性硅胶套50的上端设置有能伸入至该第一凹陷结构65内的第二遮挡部分52，在安装后柔性硅胶套50的第二遮挡部分52向上伸入至第一凹陷结构65内并遮挡住通孔651，当然同时也遮挡住了通气槽66的端口，如图8所示。而进一步当储液腔12内变为负压时，通过流体的压力传递，第二遮挡部分52产生形变向下收缩至图9所示的状态，从而使被遮挡的通孔651和通气槽66端口的一部分露出，进而使通孔651通过通气槽66与储液腔12连通，从而供外部空气沿图9中箭头R4所示进入至储液腔12内在一定程度上降低负压。
在设计上，参见图10所示，柔性硅胶套50的第二遮挡部分52是位于两个第三导液通道51之间的位置，通过减低抗弯强度使其利于变形。同时减低其厚度至大约0.2～0.5mm，并且材料上采用邵氏硬度A型20A至40A的硬度范围内。并且为了提升其在较低的压力下能具有更加大的形变倾向，第二遮挡部分52自身不是平面的形状，而是凹凸的起伏的波浪形状，并且第二遮挡部分52中央设置有与凸起方向相反的 第二凹陷结构521，该第二凹陷结构521一方面用于减低第二遮挡部分52的厚度，另一方面进一步降低抗弯强度，使其更容易产生形变。
或者在图11所示的柔性硅胶套50a的又一个实施例中，至少部分相对其他部分凸出的第二遮挡部分52a上，设置有多个或若干第二凹陷结构521a，使其呈沿雾化器100的横截面方向延伸的波形的形状，用于降低第二遮挡部分52a的抗弯强度使其更加容易变形。
在图12和图13所示的又一个可变的实施例中，通过在刚性支撑架60a和柔性硅胶座70a之间形成用于在储液腔12负压时供外部空气进入的空气通道；具体，
在一个实施例中，刚性支撑架60a沿宽度方向的第一端外侧壁上设置有沿长度方向延伸的凹槽63a，在安装后该凹槽63a与柔性硅胶座70a的内壁之间形成用于供雾化腔内的空气进入至储液腔12的空气通道；而对应柔性硅胶座70a上设置有第一遮挡部分73a遮盖住凹槽63a的端口，并且该第一遮挡部分73a能在储液腔12内部负压时向储液腔12内微微翘起或弯曲，进而打开凹槽63a的端口；
在图12和图13中，刚性支撑架60a沿宽度方向的第二端外侧壁上设置有沿长度方向延伸的凸棱67a，在安装后该凸棱67a使得刚性支撑架60a第二端外侧壁与柔性硅胶座70a内壁之间无法完全贴合而保持有一定的空隙，进而通过空隙形成用于供外部空气进入至储液腔12内的空气通道；当然，与该凸棱67a相对的第一遮挡部分73a是遮盖住由凸棱67a形成的空气通道的端口的，并且在储液腔12负压时向储液腔12内微微翘起或弯曲，进而打开由凸棱67a形成的空气通道的端口。
更进一步在图12所示的优选实施例中，为了使第一遮挡部分73a更容易地在储液腔12负压时向上翘起或弯曲变形，柔性硅胶座70a设置有沿厚度方向分别位于第一遮挡部分73a两侧的减强槽74a，通过该减强槽74a使第一遮挡部分73a大部分是悬挂或悬吊状态，进而更加便于翘起或弯曲变形。当然在可变的实施例中，该减强槽74a还可以被替换为若干镂孔，通过孔来减少第一遮挡部分73a与其他部分的连接面积减低其抗弯强度进而促进其易于变形。
在图14所示的又一个优选的实施例中，柔性硅胶座70b围绕第一遮挡部分73b的减强结构74b可以呈图中靠近或者围绕第一遮挡部分73b的孔、槽、或者是由第一导液通道71向外延伸形成的缺口等的结构，这些结构的目的均是降低第一遮挡部分73b的抗弯强度，使其更加易于翘起和变形。同样，还可以在第一遮挡部分73b上设置一凹陷741b，同样也可以减低第一遮挡部分73b的抗弯强度。
当然在图12和图14所示的优选实施例中，第一遮挡部分73/73a通过围绕它们的槽、缺口等结构进而形成与柔性硅胶座70/70a的其他部分是呈图中所示的悬挂连接的结构，进而更加便于翘起或者弯曲等形变。
或者在图15和图16所示的又一个变化的实施例中，向储液腔12内补充空气的通道是形成于多孔体30b上的。具体在图15和图16中，多孔体30b上设置有沿雾化器100的长度方向贯穿的孔34b，并由该孔34b作为向储液腔12内补充空气的通道；对应柔性硅胶套50b上设置有沿雾化器100的横截面方向延伸并遮盖孔34b的第三遮挡部分53b，而该第三遮挡部分53b可以相应储液腔12的负压进而产生向上翘起或者弯曲的形变，进而打开孔34b使得外部空气能补充至储液腔12内。
或者在以上图15和图16的其他变体实施例中，空气通道是由多孔体30b与柔性硅胶套50b之间形成的，比如多孔体30b和/或柔性硅胶套50b内壁上的凹槽结构等等。
图17示出了又一个可选实施例的柔性硅胶座70c的结构示意图；其具有对应用来遮挡支撑架60的通孔63的第一遮挡部分73c，该遮挡部分73c上与通孔63的端口相对的至少一部分形成沿背离通孔63朝储液腔12内的凸起731c；进而该凸起731c上可以通过切割、刀划等方式形成的切口或狭缝732c；在非抽吸状态第一遮挡部分73c自身受液体基质的压力使切口或狭缝732c闭合的，当抽吸的过程中储液腔12内部的负压逐渐增大至一定时切口或狭缝732c能扩大进而使通孔63的端口打开，从而向储液腔12补充空气。
或者在又一个可选的实施例中，图18示出了又一个雾化器100d的结构示意图；支撑架60d的通孔63d作为用于向储液腔12补充空气的 通道；在通孔63d的端口上设置有遮挡通孔63d的柔性材质遮挡塞73d，该遮挡塞73d是被一个弹簧元件74d以弹性力抵靠在通孔63d上的；当抽吸的过程中储液腔12内部的负压逐渐增大至一定时，外部的气压压力大于弹簧元件74d的弹性力时则遮挡塞73d会被冲开进而使外部空气进入至储液腔12内。当储液腔12内的负压下降至一定时弹簧元件74d的弹性力重新使遮挡塞73d关闭通孔63d。
以上雾化器和电子烟，利用柔性硅胶部件的柔性使其能响应储液腔的负压进而产生弹性形变，进而打开空气通道，使外部空气能通过空气通道进入至储液腔内部分缓解负压程度，使液体基质的传递顺畅。
当然以上实施例，柔性部件自身是具有一定的抗形变能力的，进而在使用中能使得储液腔12内部在不抽吸时使空气孔道呈常闭状态，使储液腔12维持有一定的负压状态；而只有当抽吸过程中储液腔12内负压增大至超过一定的临界阈值时柔性部件响应以上负压变化发生形变供空气进入；从而在能防止储油腔12不是恒定的常压状态而避免液体基质直接通过多孔体30渗漏。
进一步在图19所示的实施例中提出了一种具有更优的密封效果防止液体基质在各部件的接合缝隙之间渗漏的多孔体30c和柔性硅胶套50c的结构；具体，
多孔体30c包括：
沿雾化器100的横截面方向延伸的基体部分310c，该基体部分310c的上下表面则可以分别被作为以上所述的吸液面和雾化面。
第一延伸臂320c和第二延伸臂330c；由基体部分310c沿雾化器100的长度方向向上延伸形成；在图19中所示的优选实施例中，第一延伸臂320c和第二延伸臂330c分别沿着雾化器100的厚度方向设置于基体部分310c相对的两侧；
进一步在图19所示的优选实施例中，多孔体30c还包括于第一延伸臂320c和第二支撑部分320c之间沿雾化器100的横截面方向延伸的支撑部分340c。
柔性硅胶套50c大体呈中空的筒状，包裹在多孔体30c外。
柔性硅胶套50c外表面上设有若干用于在安装之后提升密封效果的凸筋，这些凸筋主要是密封支撑架60和多孔体30c之间的液体基质传递通道，以防止液体传递的过程中由支撑架60和多孔体30c之间的缝隙渗漏；因而在实施例中，若干凸筋共同使形成闭合的环形，并且是完整环绕或包围体传递通道的，进而实现比较好的密封效果；具体包括：
第一凸筋510c，数量为两段，分别设置于柔性硅胶套50c沿宽度方向的两个外侧壁上；并且在图中第一凸筋510c呈沿厚度方向延伸。
并且在装配后的位置上第一凸筋510c与多孔体30c的基体部分310c是对应或重合的，进而使得该第一凸筋510c能由基体部分310c提供支撑，使第一凸筋510c能紧密的抵靠在支撑架60的内壁上。
第二凸筋520c，数量为两段，分别设置于柔性硅胶套50c的顶壁表面靠近厚度方向的两侧上；在图中被构造呈沿宽度方向延伸，并且在位置上分别是支撑部分340c相对的，进而在安装后能由支撑部分340c提供支撑，使第二凸筋520c能紧密的抵靠在支撑架60的内壁上。
第三凸筋530c，数量包括有四段，具体是分别设置于柔性硅胶套50c沿厚度方向的两个外侧壁上(在图中对侧的两段第三凸筋530c被遮挡进而未显示)；并具有沿长度方向的第一端与第一凸筋510c连接、第二端与第二凸筋520c连接。在安装之后，第三凸筋530c由第一延伸臂320c和第二延伸臂330c的外侧壁提供支撑，使第三凸筋530c紧密地抵靠于支撑架60的内壁上。
根据图19的优选实施例，第三凸筋530c的数量共有四段，进而通过相连的方式使设置于柔性硅胶套50c上的第一凸筋510c、第二凸筋520c和第三凸筋530c连接形成闭合的形状。当然，以上由凸筋形成的闭合的形状是具有沿雾化器100的长度方向具有跨度的非平面的闭合环。
同时根据图19的优选实施例，第三凸筋530c是沿宽度方向向外倾斜设置的。
进一步在图19所示的优选实施例中，柔性硅胶套50c上设置有位于 相对的两个第二凸筋520c之间的承接孔540c，在实施例中该承接孔540c是与刚性支撑架60上的通孔651相对的，进而可以使在烟气传输管11内传输的气溶胶的冷凝液向下坠落进而通过承接孔540c被支撑部分340c承接和吸收。
图20提出了又一个可选的实施例的柔性硅胶套50d上设置凸筋提升密封效果的示意图，在该实施例中具有两个相互分离、并且各自呈闭合的环形的凸筋；具体：
由设置于一宽度方向的侧壁上的第一凸筋510d、设置于顶部上的第二凸筋520d和位于厚度方向的两个侧壁上的两段第三凸筋530d组成第一闭合的环；
同样地，还包括有另一个第四凸筋511d、第五凸筋521d和两段第六凸筋531d组成第二闭合的环。
当然，以上若干凸筋形成的闭合的环是相互独立，以及沿宽度和厚度方向对称设置于柔性硅胶套50d上的。
在图20所示的优选实施例的凸筋结构布置上，两个对称的闭合的环，分别各自围绕两个流体连通口51d，进而防止在液体基质传递的过程中从支撑架60与多孔体30c之间的缝隙渗出。
并且根据图20所示的优选实施例中，柔性硅胶套50d沿厚度方向的两侧设置有通过凹陷形成的在抽吸过程中供气溶胶输出的通道部分540d，形成抽吸过程中气流路径R2的一部分。对应第三凸筋530d和第六凸筋531d是分别布置在该通道部分540d两侧的。
进一步根据图19和图20所示的优选实施例，形成的闭合的环形凸筋的延伸路径是完整地经过柔性硅胶套50c/50d的全部外表面的，即柔性硅胶套50c/50d沿宽度方向的左右两外侧壁、厚度方向的前后两个外侧壁、以及顶壁外表面上均是有闭合的环的一部分在它们上延伸。
在图21所示的又一个可选的实施例中，柔性硅胶套50e的两个闭合的环形的凸筋中，第二凸筋520e包括相互呈一定夹角的两个部分组成；对应第五凸筋521e类似同样具有呈一定夹角的两个部分。
当然在该图21所示的柔性硅胶套50e中，第二凸筋520e和第五凸 筋521e同样均是由支撑部分340c提供支撑的。
并且在该图21所示的柔性硅胶套50e，实施例中图21中由若干凸筋顺次连呈的两个闭合的环形是可以相连的。
同时，在以上图19至图21所示的优选实施例中，以上若干凸筋是沿着雾化器100的厚度方向或宽度方向呈对称设置的。
以上电子烟雾化器采用对应适配于具有支撑部分33/340c的多孔体30/30c的结构，在柔性硅胶套50c/50d/50e上设置能与多孔体30/30c的各部分对应的凸筋，从而使得在装配后能比较完全地使多孔体30/30c与刚性支撑架60/60a之间紧密地抵靠并隔离导液通道，提升密封效果。
