具体地，如图1和2所示，所述雾化装置13包括第一导液元件131、第二导液元件132、加热元件133、温敏元件134及雾化器座体135。所述第一导液元件131的一端与烟液腔12连通，另一端连接第二导液元件132，用以将烟液腔12中的烟液通过毛细作用输送至第二导液元件132。所述第二导液元件132紧贴或靠近所述温敏元件134设置。所述加热元件133缠绕或套设在第二导液元件132和温敏元件134之上。替代地，所述加热元件133仅缠绕或套设在第二导液元件132之上。替代地，所述温敏元件134紧贴或靠近第一导液元件131，所述加热元件133缠绕或套设在第一导液元件131和温敏元件134之上，省去第二导液元件132。替代地，所述温敏元件134紧贴或靠近第一导液元件131，所述加热元件133仅缠绕或套设在第一导液元件131之上，省去第二导液元件132。替代地，将温敏元件134既作为温敏元件又作为加热元件，省去加热元件133。
所述加热元件133、温敏元件134和控制装置14电性连接。所述雾化器座体135用于固定第一导液元件131、第二导液元件132、加热元件133及温敏元 件134等元件中的至少一个元件，从而使得雾化装置13内各个元件的位置固定。其中，为了避免所述温敏元件134与加热元件133直接接触，可在所述温敏元件134外套设绝缘套或涂覆绝缘涂层。所述温敏元件134的温敏部分由正温度系数(Positive Temperature Coefficient，简称PTC)材料或负温度系数(Negative Temperature Coefficient，简称NTC)材料制成。所述PTC材料可以是陶瓷基PTC材料，也可以是聚合物基PTC材料。
具体地，如图3所示，所述控制装置14包括检测电路141、处理器142及开关电路143。所述检测电路141与温敏元件134电性连接，实时监测温敏元件134的电阻值R，并将电阻值R反馈给处理器142。所述处理器142内预先存储有温敏元件134的电阻值R与温敏元件134的温度T的对应关系数据以及工作温度上限TH和工作温度下限TL的数值。当所述温敏元件134的温敏部分由PTC材料制成时，所述温敏元件134的电阻值R随着温敏元件134的温度T的升高而增大。当所述温敏元件134的温敏部分由NTC材料制成时，所述温敏元件134的电阻值R随着温敏元件134的温度T的升高而减小。所述处理器142根据温敏元件134的电阻值R与温敏元件134的温度T的对应关系数据判断出实时温度t，将实时温度t与工作温度上限TH和工作温度下限TL进行比较，并根据比较结果控制开关电路143的通/断。所述开关电路143与加热元件133电性连接，用于闭合/断开加热元件133和供电装置15之间的电路。
具体地，如图3所示，所述供电装置15与控制装置14电性连接。
具体地，如图1-4所示，在使用过程中，第一导液元件131通过毛细作用将烟液腔12内的烟液输送至第二导液元件132，手动驱动处理器142使得开关电路143闭合，加热元件133和供电装置15之间形成回路，供电装置15向加热元件133供给电能，加热元件133发热，致使实时温度t升高，烟液受热挥发形成烟雾。与此同时，当所述温敏元件134的温敏部分由PTC材料制成时，温敏元件134的电阻值R随着温敏元件134的温度T的升高而增大。当所述温敏元件134的温敏部分由NTC材料制成时，温敏元件134的电阻值R随着温敏元件134的温度T的升高而减小。所述检测电路141实时监测温敏元件134的电阻值R并反馈给处理器142。处理器142中预先存储有温敏元件134的电阻值R与温敏元件134的温度T的对应关系数据，故可通过电阻值R判断出实时温度t。如 图4所示，处理器142将实时温度t与预先存储在处理器142中的工作温度上限TH和工作温度下限TL进行比较：当t＜TH时，处理器142控制开关电路143闭合，供电装置15向加热元件133供给电能；当t＞TH时，处理器142控制开关电路143断开，供电装置15停止向加热元件133供给电能，实时温度t自然下降，直至t＝TL时，电能供给恢复。将加热温度控制在TL～TH，可确保消费者在获得良好口感的同时避免不期望的化合物的产生与释放。
在其他实施例中，所述雾化装置13可包括两个、三个或三个以上的加热元件133和数量相同的温敏元件134。所述加热元件133与所述温敏元件134的配合关系与实施例1中相同。可以理解地，所述加热元件133的数量与温敏元件134的数量不匹配，但是，温敏元件134的数量至少为一个。
实施例2
如图5所示，本发明的另一个实施例提供了一种电子烟200，其包括烟嘴21、烟液腔22、雾化装置23、控制装置24、供电装置25及壳体26。所述烟嘴21、烟液腔22、雾化装置23、控制装置24、供电装置25和壳体26的配合关系与实施例一中相同，此处不再赘述。
本实施例的电子烟200与实施例1的不同之处在于：雾化装置的结构不同。请参照图5和图6，在本实施例中，雾化装置23包括第一导液元件231、第二导液元件232、加热元件233、温敏元件234及雾化器座体235。所述第一导液元件231的一端与烟液腔22连通，另一端连接第二导液元件232，用以将烟液腔22中的烟液通过毛细作用输送至第二导液元件232。所述加热元件233、温敏元件234和控制装置24电性连接。所述加热元件233和温敏元件234共同缠绕或套设在第二导液元件232之上。所述温敏元件234与所述加热元件233的长度比δ，优选地，应使0＜δ≤1。替代地，所述加热元件233和温敏元件234共同缠绕或套设在第一导液元件231之上，省去第二导液元件232。替代地，在加热元件233表面涂覆温敏材料，省去温敏元件234。替代地，将温敏元件234既作为温敏元件又作为加热元件，省去加热元件233。所述雾化器座体235用于固定第一导液元件231、第二导液元件232、加热元件233和温敏元件234等元件中的至少一个元件，从而使得雾化装置13内各个元件的位置固定。其中，所述温敏元件234的温敏部分由PTC材料或NTC材料制成。所述PTC材料可以 为陶瓷基PTC材料也可以是聚合物基PTC材料。
在其他实施例中，所述雾化装置23可包括两个、三个或三个以上的加热元件233和数量相同的温敏元件234。所述加热元件233与所述温敏元件234的配合关系与实施例二中相同。可以理解地，所述加热元件233的数量与温敏元件234的数量不匹配，但是，温敏元件234的数量至少为一个。
