在储液腔11的底壁和顶壁分别设置有相对的进气通道112和出气通道111。主加热构件12设置在储液腔11内并连接进气通道112和出气通道111形成一贯通的气流通道，使得气流可以经由进气通道112流入主加热构件12，再经由出气通道111流出主加热构件12。在本实施例中，主加热构件12呈中空筒状，沿其长度方向的两端分别延伸至进气通道112和出气通道111。
具体地，主加热构件12包括主加热元件121、导液元件122和固定管123。固定管123为主加热构件12的筒状最外层，以用于将主加热元件121和导液元件122固定在储液腔11中。在本实施例中，固定管123沿其长度的两端分别与储液腔11的进气通道112和出气通道111固定连接。固定管123在靠近储液腔11底壁的一端的侧壁上设置有开孔123A，使得储液腔11中的液体仅经由该开孔123A被导液元件122吸收。在本实施例中，沿固定管123的周向间隔设置有多个开孔123A。
主加热元件121为主加热构件12的筒状最内层，其位于储液腔11的沿高度方向上的中部，优选地靠近顶壁布置。主加热元件121可以由例如发热丝、发热片、发热板或发热管、或其中的两个或多个的组合、或其它可加热部件构成。导液元件122置于主加热元件121外周壁与固定管123内周壁之间，其顶端与主加热元件121的顶端大致平齐，其底端朝向储液腔的底壁延伸超过主加热元件121的底端。在本实施例中，导液元件122底端延伸至超过固定管123的开孔123A，使得导液元件122在固定管123的开孔123A处直接与储液腔11中的液体接触，并将其吸收且传导至主加热元件121上。导液元件122可以由多孔材料制成，例如海绵、棉花、纸、多孔陶瓷或其中的两个或多个的组合。
将主加热元件121布置于储液腔11的沿高度方向上的中部，优选地靠近储液腔11的顶壁布置，将固定管123的开孔靠近储液腔11的底壁布置，并通过导液元件122将两者连通，这样可以避免发生漏液的现象，即避免过多的液体流入到主加热元件121中来不及被加热雾化。
在本实施例中，主加热构件12还设置有一导气管124，其内部构成气流通道的一部分，其外径与主加热构件12的外径相当，其顶端与主加热元件121的底端抵接，并向下延伸至进气通道112处，使得其底端与储液腔11的底壁抵接。此外，导气管124的设置不仅可以实现对主发热元件在轴向上的定位，还可以起到支撑固定导液元件122 的作用。
在本实施例中，固定管123的靠近储液腔11顶壁的一端与出气通道111之间还布置有环形的密封套125，以用于防止储液腔11内的液体从固定管123与出气通道111的连接处进入到固定管123和/或出气通道111中。
辅加热构件13固定在储液腔11的底壁上。具体地，辅加热构件13被构造为片状或板状。辅加热构件13由例如发热丝、发热片、发热板、发热管或其中的两个或多个的组合、或其它可加热部件构成。在本实施例中，辅加热构件13的位置高度设置成与固定管123的开孔123A的最底端大致平齐。
在本实施例中，将辅加热构件13固定在储液腔11的底壁上，可以使其工作效率达到最大。这是因为不管储液腔11中有多少液体，辅加热构件13总能够充分与液体接触并加热。此外，由于同一种液体的密度与其浓稠度正相关，通常液体中浓稠度较高的部分会沉积在储液腔11的底部，因此辅加热构件13总能够对液体中浓稠度较高的部分进行加热使其浓稠度降低。
需要注意的是，主加热构件12和辅加热构件13是独立控制的，其各自连接独立的控制开关，使得能够分别控制两者的工作状态。在使用时，可以先将辅加热构件13打开，对储液腔11中的液体进行预加热，预加热后的液体浓稠度降低、流动性增强，能够更好地被导液元件122吸收，然后再打开主加热构件12对液体进行雾化。
在本实施例中，储液腔11内包括相互连通的第一容置部分和第二容置部分，第一容置部分和第二容置部分在储液腔的横向上并排布置。所述主加热构件12容置于第一容置部分内。所述液体主要容置于所述第二容置部分内，且所述辅加热构件13布置于第二容置部分的底部，如此，辅加热构件13被直接布置在液体中，可以有利地对其附近区域的液体进行预加热。此外，主加热构件12的开孔123A邻近第二容置部分的底部，即邻近辅加热构件13，如此可以有利地使已经经过辅加热构件13预热的液体优先地进入主加热构件12而被导液元件122吸引，继而被主加热元件121加热。
在本实施例中，储液腔11由雾化装置外壳14和安装座15围合而成。雾化装置外壳14构成了储液腔11的侧壁和顶壁，安装座15构成了储液腔11的底壁。在本实施例中，进气通道112设置在安装座15上，出气通道111设置在雾化装置外壳14的远离进气口的一端。
在本实施例中，同时参见图3，安装座15整体构造成平板状，包括密封件151和支撑件152。其中，密封件151由硅胶制成。具体地，进气通道112设置在支撑件152上。密封件151包括第一部分和第二部分，分别对应于储液腔11的第一容置部和第二容置部。第一部分设置有一贯穿其厚度的且与进气通道112相对应的通孔151A，使得密封件151能够形状配合地套设在支撑件152上。主加热构件12穿过该通孔151A与进气通道112连接。第二部分朝向储液腔11顶壁的一侧设置有一容置槽151B，以用于固定辅加热构件13。
储液腔11在其侧壁上还设置有注液开口113。在本实施例中，注液开口113设置在雾化装置外壳14的一侧。在具有注液开口113的侧壁外侧还设置有一雾化装置侧盖16，以用于封闭注液开口113。在本实施例中，雾化装置侧盖16可滑动地连接在雾化装置外壳14的一侧，使得通过滑动雾化装置侧盖16可以打开或关闭注液开口113。在雾化装置侧盖16的与注液开口113接触的一侧设置有一密封塞161，该密封塞161的位置与注液开口113相对应以用于密封注液开口113。在本实施例中，密封塞161以嵌入的方式布置在雾化装置侧盖16中。
在本实施例中，雾化装置1的底端还设置有一底盖17，其固定在安装座15的下方，与安装座15围合成一空腔。底盖17上设置有进气孔171，进气孔171的设置的位置与进气通道112的位置错开，气流从进气孔171进入到空腔后再流入进气通道112（气流方向如图1的黑色箭头所示）。在本实施例中设置有两个进气孔171。底盖17的对应于进气通道112的位置处设置有一凹槽172，在主加热构件12内壁依附的冷凝液可以顺着进气通道112流入凹槽172中，而不会从进气孔171中流出。用于将主加热元件121和辅加热构件13与电源和控制开关电连接的电极柱（未标示）布置在凹槽172的两侧壁外。
在本实施例中，雾化装置1的顶端还设置有一吸嘴18，其连接于出气通道111的上方并与出气通道111对齐，雾化后的液体和气流混合后从出气通道111流出后经过吸嘴18被用户吸入。
根据本发明的第二方面，提供了一种电子烟100，参见图4，其包括根据本发明第一方面的雾化装置1、以及与该雾化装置1电连接的电源及控制装置2。
参见图5，电源及控制装置2主要包括电池构件21、控制构件22和支撑架23。电池构件21包括用于储存和提供电量的电池芯211。该电池芯211被收容在托架212中，以固定和保护电池芯211。在托架212上还布置有一充电电路板213，其与电池芯211电连接，当该充电电路板213与外部电源接通时可以对电池芯211进行充电。
控制构件22固定于支撑架23中并与电池构件21电连接。具体地，控制构件22包括主加热控制开关221和辅加热控制开关222，分别用于控制主加热元件121和辅加热构件13的通电和断电。在本实施例中，主加热控制开关221为气流感应开关，其可布置在与雾化装置1气流相通的位置处，当感应到一定的气流量通过时，触发气流感应开关打开主加热元件121。在本实施例中，辅加热控制开关222为普通的按键开关，用户可以手动触发该按键开关以打开辅加热构件13。
支撑架23与电池构件21的托架212固定连接，在本实施例中，通过卡扣的方式连接。支撑架23内设置有一用于收容雾化装置1的内腔231。内腔231的远离电池构件21的一端具有一开口，雾化装置1的吸嘴18可通过该开口伸出内腔。
在本实施例中，电源及控制装置2还包括一封装外壳24和一底座25。电池构件21的远离支撑架23的一端通过插入的方式固定至底座25中。电池构件21、支撑架23和底座25收容于封装外壳24中。在封装外壳24上还设置有与辅加热控制开关222连接的按键26，以供用户手动控制辅加热控制开关222。
在本实施例中，电子烟100还设置有一盖体3，以用于保护吸嘴18。该盖体3可拆卸地与封装外壳24连接，并构造成与封装外壳24和底座25围合成一密闭的空间。
以上所述仅为本发明较佳的具体实施方式，本发明的保护范围不限于以上列举的实施例，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，可显而易见地得到的技术方案的简单变化或等效替换均落入本发明的保护范围内。
