本发明的最佳实施方式
本发明下面将结合附图作进一步详述：
图1、图2、图3示出了本发明的第一实施例。
如图1、图3所示，本发明电子烟雾化器第一实施例，具有一外壳6，外壳6的一端设有可拆卸的吸嘴1，吸嘴1设有吸烟的气道101，外壳6的另一端套接螺纹连接座18，该螺纹连接座18设有内螺纹181以便与电子烟的电池杆(图中未示)进行连接，使本发明电子烟雾化器与电池杆连接成为一支完整的电子烟。
如图1、图2、图3 所示，本实施例的吸嘴1外径呈喇叭形变化，符合人体工程学原理，适应嘴唇舒适使用吸嘴，其与外壳6连接的一端缩小外径成管状，管状外壁紧密套设有外螺纹连接件3，而外壳6、外管7内壁同时紧密套设有与外螺纹连接件3配对的内螺纹连接件4，如此，吸嘴1即可与外壳6进行螺纹连接并可拆卸，另吸嘴1 外螺纹连接件3上部设有O形密封圈2用于防止烟液从螺纹间渗漏，内螺纹连接件4与外壳6接合处设有O形密封圈5用于防止烟液从两者结合处渗漏。另外，从本实施例可以简单地作出变化，即外螺纹连接件3也可以与吸嘴1做成一体，内螺纹连接件4可以与外壳6使用同一种材料做成一体。
如图2所示，本实施例的吸嘴1在吸口处向内延伸有一吸嘴内管102，吸嘴内管102与吸嘴的气道内壁之间的间隙形成凹腔，用户吸烟时，烟雾通过烟嘴1的气道101向吸口流出时，因吸嘴内管102管孔变小，部分烟雾在凹腔内形成回流，烟雾中未被雾化的小液滴即凝结于凹腔内，有效防止了未被雾化的烟液吸入到用户口中，提升了用户的良好吸烟体验。
如图1、图3 所示，外壳6内紧密套设一外管7，外管7内轴向设有内管10，内管10内轴向设有雾化管15，雾化管15内设有烟气通道及雾化腔23，雾化腔23与吸嘴1的气道101相通，雾化腔23内设有导液芯13及缠绕于部分导液芯13上的电热丝12。外管6、内管10、雾化管15的一端分别与吸嘴1 密封连接，另一端与螺纹连接座18密封连接，外管7、内管10、吸嘴1与螺纹连接座18之间形成封闭的储液腔21用于储存烟液。上述储液腔21及吸嘴1的结构，可使得拆卸吸嘴1时，储液腔21即可敞开一端，这样用户在烟液用完时，可自行将烟液从储液腔21敞开的开口处补充进储液腔21，达到重复使用该电子烟雾化器的目的。
为便于观察储液腔21内的烟液余量，本实施例在外壳6上开设有长条形的窗口61，外管7使用透明材料制成，如此即可方便用户在吸烟时随时观察到储液腔21内的烟液余量，并据此判断是否需要添加补充烟液。
如图1、图3所示，内管10的管壁上设有若干小孔102，内管10与雾化管15之间在靠近吸嘴1的一端设有雾化隔套9，另一端设有密封环16，内管10、雾化管15、雾化隔套9、密封环16 之间形成封闭的导液腔22。雾化管15靠近吸嘴1一端的管壁上设有对称的两个缺口151，导液芯13呈U 字形架设于缺口151上，其中电热丝12缠绕于雾化管15内两个缺口151之间的导液芯13上，导液芯13未缠绕电热丝12的两端伸入到导液腔22中并贴附于雾化管15的外壁，雾化隔套9罩住缺口151及部分导液芯13。本发明的上述结构，使得电子烟的烟液可从储液腔21通过内管10管壁上的小孔102节流流入导液腔22，两端伸入到导液腔22中并贴附于雾化管15的外壁的导液芯13自导液腔22中吸收烟液并传导至电热丝12部分，使烟液可以进行加热雾化，由于雾化隔套9的作用，避免烟液直接通过缺口151渗漏到雾化腔23中，雾化隔套9同时套紧了导液芯13，使得导液芯13可以稳定张紧地架设于雾化管15的缺口151上，有利于雾化效果持续稳定。另本发明的上述导液腔的结构，使用户在补充烟液后，因烟液不能立即充满导液腔22，这样在用户装回吸嘴时，因吸嘴密闭储液腔21导致储液腔21内的压力增加使烟液可以缓冲流入导液腔22，导液腔22内的空气在压力作用下经导液芯13的缝隙从雾化管缺口151排出，避免了安装吸嘴时造成的烟液泄漏。
为避免储液腔21中的烟液从吸嘴1与内管10连接处渗漏，吸嘴1与内管10之间设有吸嘴密封套8，该吸嘴密封套8呈杯状套设于内管10一端且于杯底部中间设有吸烟通孔，本实施例中，吸嘴密封套8的杯状底部还设有凸起且外径变小的圆台81，圆台81中心设有吸烟通孔，该圆台81外壁可与吸嘴1的气道101的内壁更好地密封套接，以加强密封效果，另外，该圆台81顶部与外管7端部平齐，如此可以在烟嘴1拆卸后注入电子烟液时，可以更顺畅地注入到储液腔21中，同时避免烟液因不慎被注入至雾化腔23。
如图1、图3所示，螺纹连接座18紧密套接于外壳6一端，该螺纹连接座18设计成五级缩径管状体，其不同的外径除与外壳6外，同时还与外管7、内管10、雾化管15套接连接，其中，外管7、内管10与螺纹连接座18之间还设有烟液密封套 17用以防止烟液从其中缝隙渗漏。
本实施例中，该螺纹连接座18为金属材料制成，可导电，故其可兼作与电热丝12相电性连接的其中一个电极，电热丝12还电性连接至另一个电极即雾化电极20，如图1、3所示，雾化电极20呈管状套设于螺纹连接座18的中心通孔内，雾化管15为可导电的金属管，电热丝12的一端引线与雾化电极20连接，另一端引线与雾化管15连接，雾化电极20与螺纹连接座18之间设有绝缘套19，雾化电极20的一端伸入到雾化管15内并与雾化管15之间设有密封绝缘套11。本实施例中雾化电极20设计成中空的管状，以便空气可从雾化电极20的管内通过而进入雾化腔23，为此，雾化连接座及外管上还需设有进气口24以便空气进入雾化电极20，该进气口24也可设于电池杆上，当本发明的电子烟雾化器与电池杆连接后，进气口进入的空气可经雾化连接座18再进入雾化电极20。
 本发明的实施方式
图4、图5、图6示出了本发明的第二实施例。
如图4、图5、图6所示，本发明电子烟雾化器，与第一实施例不同在于，吸嘴1与外壳6采用旋转卡扣的方式进行连接。
第二实施例的吸嘴1与外壳6连接的一端缩小外径成管状，该外管壁上设有两个对称的凸扣103，外壳6、外管7内壁同时紧密套设有卡槽连接件25，该卡槽连接件25上设有供凸扣103插入并可旋转卡紧的卡槽251，吸嘴1与外壳6通过凸扣103与卡槽251配合卡紧的方式进行连接。本实施例的结构，使得吸嘴1可与外壳6进行卡扣连接并可拆卸，另吸嘴1缩径的管状上部设有O形密封圈2用于防止烟液渗漏。
 工业实用性
以上所述仅为本发明的较佳实施例，凡依本发明权利要求范围所做的均等变化与修饰，皆应属本发明权利要求的涵盖范围。
