储液组件10包括储液外壳11和设置在储液外壳11上的两个电极连接件12，储液外壳11包括储液壳体111和设置在储液壳体111一端的端盖112，储液壳体111为一端开口的中空筒状结构，储液壳体111内部中空形成储液腔113，储液壳体111远离端盖112的一端内壁朝向端盖112方向延伸形成通气管114，且储液壳体111上设置有与通气管114的内腔连通的出烟口116。端盖112安装在储液壳体111的开口端以封闭储液腔113，端盖112上凹陷形成有与储液腔113连通的安装槽115，安装槽115的内壁上设置有台阶面1151，端盖112上开设有进气孔1121，两个电极连接件12设置在端盖112上，其中一个电极连接件12与所述电源装置的正、负极中的一个电极电性连接，另一个电极连接件12与所述电源装置的正、负极中的另一个电极电性连接。
在其中一个具体地实施方式中，储液组件10还包括连接件13，连接件13收容在储液壳体111的开口端内，连接件13上设置有通孔131和连通孔，通孔131与安装槽115相连通，所述连通孔与进气孔1121相连通，连接件13的设置 增强端盖112与储液壳体111之间的密封性，防止储液腔113内的气溶胶形成基质从端盖112和储液壳体111之间泄露。可以理解地，本实施方式中，连接件13由硅胶或橡胶等密封材料制成。
雾化组件20包括雾化管21和收容于雾化管21内部的发热结构22。
雾化管21收容在储液腔113内，雾化管21的一端与连接件13连接，雾化管21的另一端与通气管114连接，雾化管21内部中空形成雾化腔211，雾化腔211与进气孔1121和通气管114的内腔均连通；雾化管21的侧壁上开设有进液孔212，进液孔212与储液腔113和雾化腔211均连通。
发热结构22收容于雾化腔211内，发热结构22包括相互接触的导液件和发热件，所述吸液件用于吸收气溶胶形成基质，所述发热件用于加热吸液件上的气溶胶形成基质。所述导液件贴合雾化管21设置，所述发热件上设置有两个引脚，一个所述引脚与一个电极连接件12对应并电性连接，进而使得所述发热件与所述电源装置电性连接。使用时，储液腔113内的气溶胶形成基质经由进液孔212进入至雾化腔211内，所述导液件吸收并储存气溶胶形成基质，启动气溶胶发生装置，所述发热件在所述电源装置的电驱动作用下加热气溶胶形成基质生成烟雾，用户抽吸时，外部气体通过进气孔1121进入至雾化腔211内并与烟雾混合，混合后的气体通过通气管114的内腔以及出烟口116进入至用户口中。可以理解地，本实施方式中，所述吸液件可以是棉花、纤维绳、多孔陶瓷、多孔石墨或泡沫金属中的任意一种，所述发热件可以是发热丝、发热片或发热筒中的任意一种。
在其中一个具体地实施方式中，雾化管21包括外套管213和收容在外套管213内的内套管214，外套管213和内套管214均为两端开口的中空筒状，雾化腔211由内套管214的内腔形成，进液孔212设置在外套管213上，内套管214 上设置有与进液孔212连通的流通孔，内套管214和外套管213之间设置有暂存气溶胶形成基质的间隙，防止储液腔113内的气溶胶形成基质大量流进雾化腔211内，发热结构22来不及雾化。
注液结构30包括套管31、弹性件34、设置在套管31内并与所述套管31固定连接的定位件32、可滑动地设置在套管31与定位件32之间的注液管33以及设置在注液管33，弹性件34的一端与套管31相抵持，弹性件34的另一端与注液管相抵持。需要说明的是，套管31与定位件32可拆卸连接或者不可拆卸连接，可拆卸连接可采用螺纹，卡接等方式，不可拆卸连接可采用紧配连接，焊接等，或者所述套管31与所述定位件32可一体成型。
如图1、图3以及图4所示，套管31大致呈中空筒状结构，套管31的一端开口形成开口端311，套管31上由靠近开口端311的方向向远离开口端311的方向上依次设置有排气口315和第一注液口312，套管31的外壁上凸设有抵持缘314，套管31设置在安装槽115内，排气口315和第一注液口312均与储液腔113连通，抵持缘314与台阶面1151相抵持，以便安装套管31时进行限位。
定位件32的一端连接在套管31内腔的底壁上，定位件32的另一端收容在套管31内，定位件32包括定位件本体323和设置在定位件本体323一端的密封部321，密封部321设置在定位件本体323远离套管31底壁的一端，本实施方式中，密封部321和定位件本体323形成T型结构，定位件本体323靠近密封部321处沿径向凹陷形成有容纳槽322。注液结构30还包括第一密封件35，第一密封件35套设在定位件本体323外部并收容在容纳槽322内。本实施方式中，定位件32与套管31一体设置，可以理解地，在其它未示出的实施方式中，定位件32和套管31可以分体设置，套管31的底壁上开设有安装定位件32的收容槽。定位件32的设置防止向远离定位件32的方向滑动注液管33时，注液 管33与定位件32相脱离。
注液管33大致呈一端具有开口的中空筒状结构，注液管33的一端设置有滑动部335，注液管33远离滑动部335的一端开口形成第二注液口336，即注液管33远离第一注液口312的一端设置有第二注液口336。本实施方式中，滑动部335为凸设在注液管33一端的凸起，滑动部335上开设有贯通孔331，贯通孔331的孔径尺寸介于定位件本体323的外径尺寸与密封部321的外径尺寸之间，且贯通孔331的孔径尺寸小于第一密封件35的外径尺寸，注液管33的另一端设置有凸缘332，凸缘332的直径尺寸大于套管31的直径尺寸，注液管33的外周壁上沿周向凹陷形成有容置槽333。注液结构30还包括第二密封件36，第二密封件36套设在注液管33的外部，第二密封件36的内圈收容在容置槽333内，第二密封件36的外圈夹设在套管31和注液管33之间，使得第二密封件36夹设在套筒31与注液管33之间。注液管33收容在套管31内，且滑动部335通过贯通孔331可滑动地套设在定位件本体323的外部，贯通孔的内壁与定位件本体323的外壁之间设置有间隙，该间隙形成进液通道334，进液通道334与套管31的内腔连通。
弹性件34收容在套管31的空腔内，弹性件34的一端与套管31的内底壁相抵持，弹性件34的另一端与注液管33相抵持，本实施方式中，弹性件34为弹簧，弹性件34套设在定位件本体323外部。
气溶胶发生装置处于用户正常抽吸状态时，进液通道334被密封部321密封，即滑动部335被密封部321密封，向气溶胶发生装置内注液时，如图2和图4所示，使用外力沿套管31的轴向向靠近储液腔113的方向活动注液管33，注液管33压缩弹性件34，套管31内腔中的空气通过第一注液口312排至储液腔113内，当滑动部335远离密封部321时，注液管33的内腔通过进液通道334 与套管31的内腔连通，此时可进行注液操作，注液管33内腔中的气溶胶形成基质通过进液通道334注入套管31的内腔中，然后经过第一注液口312流至储液腔113内，同时，第二密封件36位于排气口315的下方，储液腔113内的气体依次经过排气口315和开口端311排至注液结构30外，从而平衡储液腔113内外的气压，防止因为气压问题导致气溶胶形成基质不能注入储液腔113内；外力撤销时，在弹性件34的弹性恢复作用力下，注液管33向上移动，直至注液管33抵持在第二密封件36处，即密封部321被滑动部335密封，注液管33停止向上移动，进液通道334被第二密封件36密封，此时，第一密封件35封闭排气口315，从而再次封闭储液腔113。
本实施方式中，凸缘332的设置方便用户按压注液管33进而进行注液操作，且沿套管31的轴向向下滑动注液管33时，凸缘332抵持在套管31的上端面以便对注液管33的滑动行程进行限位。
可以理解地，本实施方式中，第一密封件35和第二密封件36均由硅胶或橡胶等密封材料制成，第一密封件35套设在定位件本体32外部，不注液时，第一密封件35封闭进液通道334，同时增强定位件本体32与注液管33之间的密封性。第二密封件36夹设在套管31和注液管33之间，增强套管31和注液管33之间的密封性，防止储液腔113内的气溶胶形成基质通过套管31和注液管33之间的空隙泄露出去。
本实施方式中，通过设置弹性件34，向下按压注液管33时需要克服弹性件34的弹力，能够避免注液管33轻易被按压而导致储液腔113被误打开，具有较好的儿童防护作用，同时在注液完成后，注液管33能够自动复位，无需用户手动活动注液管33便可实现对储液腔113的再次封闭作用，操作简单、便捷。本实施方式中，弹性件34为弹簧。
本实施方式中，注液结构30设置在端盖112上形成的安装槽115处，从而实现注液结构30与储液外壳11之间的连接关系，可以理解地，在其它未示出的实施方式中，注液结构30也可以设置在储液外壳11上的其它位置上，例如，注液结构30设置在储液壳体111的侧壁上，此处不做限制。注液时，需要将雾化器100调整至套管31的开口端处于上方的位置，使得气溶胶形成基质在自身重力作用下流入至储液腔113内。
本实施方式中，通过在套管31上设置第一注液口312，同时，贯通孔331的内径尺寸介于定位件本体323的外径尺寸与密封部321的外径尺寸之间，贯通孔331的内壁与定位件本体323外壁之间的间隙形成与第一注液口312连通的进液通道334，相对定位件本体323滑动注液管33，注液管33与套管之间的空气可通过第一注液口312流通至储液腔113内，方便按压注液管33，同时注液时注液管33内的气溶胶形成基质通过进液通道334以及第一注液口312流至储液腔113内，结构简单，且第一注液口312可根据需要通气或通液，避免了在套管31或定位件32上开设其它流通口，降低注液结构30的加工难度。
本实用新型提供的注液结构30或雾化器100，通过在套管31内设置定位件32,以及在套管31和定位件32之间可滑动地设置注液管33，通过注液管33在套管31内相对定位件32滑动，即可进行注液操作，操作简单，注液方便。
本实用新型提供的气溶胶发生装置，因其具有上述雾化器100全部的技术特征，故具有与上述雾化器100相同的技术效果。
以上述依据本实用新型的理想实施例为启示，通过上述的说明内容，相关的工作人员完全可以在不偏离本实用新型的范围内，进行多样的变更以及修改。本项实用新型的技术范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
