 本发明的最佳实施方式
如图1、图2所示，本发明一种可预热烟液的电子烟雾化器，该电子烟雾化器与电池杆连接时组成电子烟，雾化器包括吸嘴壳1，吸嘴壳1的一端中心设有吸口10、相对的另一端设有开口12，吸口10向内竖直连接设有出烟管11，吸嘴壳1位于吸口10一侧的内部设有用于储存烟液的空腔即储液腔13，吸嘴壳1位于开口一侧的外部设有缩小外径的插接部14，插接部14用于插接到电池杆（图中未示）的连接端内。吸嘴壳1位于插接部14上面的横截面设为自下而上外径渐缩的椭圆形结构，这样可方便嘴唇咬合吸嘴壳1上部，适应人体工程学的需要，而插接部的横截面设为椭圆形结构，方便从上而下的自然过渡，以及与椭圆形电池杆的连接。
如图3-图5所示，吸嘴壳1内，自出烟管11向开口12一侧依次连接设有密封套2、导热管3、雾化单元4、雾化座5、底座6，雾化单元4包括导液条41和缠绕于导液条41中段的电热丝42，与电热丝42两端连接有引线43；密封套2的内壁套设于出烟管11的外壁，导热管3的上端内壁套接于密封套2的外壁，密封套具有密封连接出烟管11与导热管3的作用。出烟管11在吸口10处设置成向外扩张的喇叭口结构，喇叭口结构有助于增大烟雾量和减少烟雾中水滴或液滴的含量，因为烟雾中的水滴或液滴通过喇叭口结构时容易附着于喇叭口内壁，而减少了直接被用户吸入口中的几率。储液腔13由吸嘴壳1的内壁、出烟管11的外壁、导热管3的外壁、雾化座5上端合围而成，导热管3与储液腔13的烟液直接接触，可将电热丝42加热时产生的热量传导给烟液以便预热烟液和降低其粘度，增强烟液的流动性。
导热管3由容易导热的材料如金属材料制成，在电子烟启动预热程序时，雾化单元4产生预热热量，或电子烟正常工作时，雾化单元4产生工作热量，预热热量或工作多余的热量通过导液条41传导给导热管3，或通过辐射、或通过热空气传导给导热管3，导热管3收集的热量可迅速传导给烟液，烟液得以预热、粘度降低流动性增加，使烟液可以较快通过导液条41传导至电热丝42处，使电热丝42雾化烟液的量增大，烟雾随之增加。此预热功能使该电子烟雾化器适用于雾化较稠的烟液、膏状或蜡状烟液等。
雾化座5的上端还连接设有用于支撑固定雾化座的环形支架7，环形支架7用于向下及横向支撑软性的雾化座5，在高温时，雾化座5进一步变软，容易发生变形导致导热管3与雾化座5接触不良而产生泄漏，烟液容易从储液腔13泄漏到凹腔52内进一步泄漏出电子烟外面。进一步地，环形支架7的下部还设有支架脚71，雾化座5的上部设有支架槽57用于容纳支架脚71，支架脚71与支架槽57咬合连接，可以使环形支架7更好地支撑固定雾化座5，防止电子烟雾化器高温工作时产生烟液的泄漏。
如图5-图9所示，雾化座5设于插接部14的内壁，雾化座5的上端设有凸起的围壁51，围壁内向下设有凹腔52，凹腔底部中心向下设有第一进气孔53，围壁上设有相对的半环槽54，导液条架设于半环槽54上，导热管3的下端内壁套接于围壁51的外壁，导热管3下端设有缺口31以便导液条伸出来。凸起的围壁51、凹腔52及半环槽54，可以很好地架设导液条41，凹腔52与上方导热管3的空腔构成了较大的雾化腔8，导液条41与发热丝42可以更多地接触空气，使烟液更好地得到雾化，从而产生更多的电子烟烟雾。导热管3下端设有缺口31以便导液条41横向直线伸出来，使得导热管3可以自上方压住导液条41的两端，使导液条41中段不会变形下陷，维持稳定的雾化条件，导液条41伸出导热管3的外面，即伸出到储液腔13的底部，使得导液条41两端可以直接接触到储液腔13内的烟液，可以更多更快地给雾化单元4供应烟液，从而使烟液雾化顺畅，使用户得到更好的吸烟体验。另外，导液条41横向直线架设，两端伸出到储液腔13直接接触烟液，也可以在电子烟预热时将电热丝42的热量传导致储液腔13内的烟液，起到一定的预热作用。
雾化座5的横截面设为椭圆形结构，围壁51的横截面也设为椭圆形结构，围壁51横截面椭圆形的长轴与雾化座主体横截面的长轴呈一定夹角，这样的结构可以使凹腔52具有更大的容积，雾化量增加的同时，又可以使后述注液通孔56有紧凑的位置安排，避免增大雾化座的横向面积，即避免加大电子烟横向面积。雾化座5由耐高温的硅胶制成，雾化座5的外壁设有多道一体成型的密封环58，这样有助于增加雾化座5与吸嘴壳1的内壁的密封性，防止烟液自储液腔泄漏。
雾化座5位于围壁51的外壁处设有向下的环形槽55，环形槽55用于容纳固定导热管3，这样环形槽55可以夹住导热管3，使两者连接更紧密，具有很好的支撑固定作用，以及具有更好的密封性。
雾化座5设有上下贯通的注液通孔56，底座6上设有与注液通孔56位置相对应的柱塞63，柱塞63用于通过注液通孔56给储液腔13注液后堵塞注液通孔56，避免烟液泄漏。柱塞63贯穿注液通孔56，故同时具有支撑固定雾化座5的作用，防止软性的雾化座5在高温时发生变形导致与吸嘴壳的松脱，避免松脱导致的烟液泄漏。
如图10-图12所示，底座6设于雾化座5的底端并卡接于吸嘴壳1开口侧的内壁，底座6上设有第二进气孔61及与电热丝两端引线电连接的正负电极62，以及设有用于安装正负电极62的电极孔621，底座6具有向上支撑固定雾化座5的作用。
底座6包括底板64和侧壁65，侧壁65上设有凸扣651与吸嘴壳1内壁设有的卡槽进行卡扣连接。设有侧壁65后，底板64与雾化座5底部则具有空间间隙，该间隙用于空气进入到雾化座5的第一进气孔53，同时该间隙还可以收集容纳雾化腔8内烟液雾化时产生并附着在雾化腔8内壁并往下流出的小液滴，防止小液滴被吸入用户口中。
底座6上设有进气管66，进气管66底部贯穿底座6与外界大气相通，进气管66上端面设有倾斜封闭的封口板661，进气管66上端靠近封口板661高侧的侧面设有第二进气孔61，封口板661的有益效果在于可以防止第一进气孔53内掉落的小液滴直接通过进气管66继续掉落到底座6的外部，甚至进一步流到电池杆内部，长期泄漏的液滴会腐蚀电池杆内的电路，造成电路的故障。倾斜的封口板661可以阻挡小液滴，并使得小液滴顺势流落到底板64和侧壁65、雾化座5的底部构成的间隙内，防止烟雾中的小液滴泄漏到底座外，进一步防止电路故障。
如图3所示，自下而上的连续箭头所示方向为空气及烟雾流动方向。本发明吸烟的工作原理是，用户吸烟时吸口10及雾化腔8产生负压，外界空气自底座6的进气管66被吸入，经雾化座的第一进气孔53、凹腔52、雾化腔8，导液条41将储液腔13内的烟液传导至电热丝42，电热丝42通电工作会产生热量，该热量将烟液加热并在雾化腔8中雾化成烟雾，雾化腔8中的烟雾在用户吸力作用下，向上流动至出烟管11，然后经吸口10被用户吸入口中。
