具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图1-3所示，本发明一些实施例的电子烟，包括本体、储液单元30、吸液件40以及发热元件50，储液单元30、吸液件40以及发热元件50均设置在本体内。本体内形成有气流通道，吸液件40包括相连接的第一部分41和第二部分42，第一部分41位于气流通道内，第二部分42位于气流通道外，该第二部分42与储液单元30导液连接；发热元件50包括发热管51，发热管51包覆于第一部分41上，且发热管51的侧壁上设有多个通孔52，通孔52由该侧壁的内壁面延伸至该侧壁的外壁面。吸液件40通过第二部分42吸取储液单元30的烟液后传导至第一部分41，烟液在第一部分41上随着发热管51通电发热后雾化形成烟雾，烟雾可通过气流通道被吸出本体。
在一些实施例中 ，吸液件40可为条状结构，横穿在气流通道上。吸液件40的中部形成第一部分41且位于气流通道中，吸液件40的两端形成第二部分42且分别露出气流通道而与储液单元30导液连接；发热管51套接在吸液件40的中部。吸液件40可采用吸液棉制成。
如图3所示， 在一些实施例中 ，发热管51呈圆筒状，其两端分别连接有电极引线511，一电极引线511用于与电源装置90（如图10所示）的正极电性连接，另一电极引线511用于与电源装置90的负极电性连接。发热管51采用可导电发热的材料制成。发热管51为侧壁闭合或具有开缝的管状结构，即，可采用整体的金属管或陶瓷管加工而成，也可以采用金属片冲孔后卷曲而成。在电子烟性能调试过程中，只需要通过调整两电极引线511之间的距离来改变两电极引线511之间的发热管51的长度，从而改变发热管51的发热面积，进而增大或减少烟雾量，操作简单、方便，便于产品设计过程中产品性能更改。
在其他实施例中，如图4所示，发热管51的中部也可连接有第一电极引线511a，发热管51的两端分别连接有第二电极引线511b，第一电极引线511a用于与电源装置90（如图10所示）的正极或负极二者之一电性连接，第二电极引线511b用于与电源装置90的正极和负极二者之另一电性连接，从而第一电极引线511a和一第二电极引线511b之间的发热管部分可形成一发热单元，第一电极引线511a和另一第二电极引线511b之间的发热管部分形成另一发热单元，两发热单元可同时或独立通电发热。
又如图1所示， 本体 在一些实施例中 可包括壳体10以及安装在壳体10上的安装座20，壳体10内部形成有纵向的中心通道101，安装座20中部形成有贯通安装座20上下相对两端的中心通孔201，且中心通孔201与中心通道101相连通形成气流通道；吸液件40横穿在安装座20上。发热管51在吸液件40的中部（第一部分41）而位于安装座20内的中心通道101中。
壳体10包括第一管状结构11和第二管状结构12，第一管状结构11的直径大于第二管状结构12的直径，第二管状结构12设置在第一管状结构11内，且二者可以同轴设置；中心通道101形成于第二管状结构12的内部，储液单元30设置在第二管状结构12和第一管状结构11之间。
储液单元30可包括形成在第二管状结构12和第一管状结构11之间并环绕中心通道的储液腔31，用于储存烟液；吸液件40的两端（第二部分42）伸入到该储液腔31直接与烟液接触而吸附烟液。可以理解地，储液单元30也可包括设置在第二管状结构12和第一管状结构11之间的储液元件；该储液元件采用储液棉制得，烟液吸附在储液棉上。壳体10的材质可以是透明的塑料，一方面容易加工塑性，另一方面可以看到储液单元30的剩余烟液量。
安装座20可安装在壳体10的一端上；如图1所示，该电子烟还包括吸嘴60，吸嘴60安装在壳体10另一端上，吸嘴60可与壳体10通过卡扣连接、螺纹连接、胶粘连接等方式固定连接在一起。吸嘴60也可以一体形成在壳体10的另一端上。储液腔31一端通过安装座20封闭并与吸液件40导液连接，储液腔31远离安装座20的另一端封闭。
如图6、7所示，并结合图1、2，在一些实施例中 ，安装座20包括底座21以及安装在底座21上的出气管22，中心通孔201形成在出气管22内部并延伸贯通底座21；出气管22顶部伸入到壳体10的中心通道101内，可将在中心通孔201内雾化的烟雾引导至壳体10的中心通道101。优选地，吸液件40横设在底座21上。
底座21可包括主体部212、分别连接在主体部212上下两侧的第一连接部211和第二连接部213，中心通孔201依次贯通第一连接部211、主体部212和第二连接部213；第一连接部211的侧壁上开设有连通中心通孔201的安装孔200，吸液件40横向设置在安装孔200内。主体部212的外径可大于第一连接部211和第二连接部213的外径。出气管22的底部凸设有环形的卡接台221，卡接台221卡设到第一连接部211上。优选地，安装孔200为开设在第一连接部211侧壁上相对两位置上的孔或缺口，两个孔或缺口相对连通形成安装孔200，吸液件40横跨在两个孔或缺口之间，稳定。
在吸液件40上，发热管51的两端还可延伸至底座21上，从而发热管51也可横跨在安装孔200上，进而加强发热管51的结构稳定性，如图8、图9所示。在一些实施例中，底座21可为绝缘底座，采用塑胶等绝缘材料制成。在另一些实施例中，底座21也为导电底座，采用导电材料如陶瓷等制成。作为一种实施方式，参考图5及图8，该底座21可形成与电源装置90（如图10所示）的负极电性连接的导电底座，发热管51通过其两端与底座21导电连接；在发热管51的中部连接一个电极引线511，用于与电源装置90的正极电性连接，从而在通电发热时，该电极引线511两侧的发热管部分可形成两个发热单元。作为另一种实施方式，参考图9，在发热管51延伸到底座21上的一端设置绝缘层53，从而发热管51一端通过绝缘层53与底座21绝缘接触，另一端与底座21导电连接；该底座21可形成与电源装置90（如图10所示）的负极电性连接的导电底座，在发热管51的靠近绝缘层53的位置处连接一个电极引线511，用于与电源装置90的正极电性连接。绝缘层53可由绝缘材料镀在发热管51上形成，也可由绝缘套套设到发热管51上形成。
安装座20还可包括密封件23，该密封件23远离底座21套设在出气管22上。密封件23位于出气管22和壳体10的第二管状结构12之间，且与第二管状结构12的内壁抵接，起到密封作用，避免烟液从储液单元30流入气流通道。出气管22的顶部穿出密封件23，且出气管22顶部的侧壁上开设有连通出气管22内部和中心通道201的通孔220。该通孔220可以使中心通道101内凝结的烟液回流至安装座20的中心通孔201中，防止出气管22顶部的端部开口处由于烟液的粘性大、表面张力大，形成薄膜，阻碍烟液从出气管22的端部开口回流到中心通孔201中。出气管22上通孔220可为一个或多个，形状不限定。
密封件23在出气管22上还可以延伸至出气管22与底座21的连接处，将该连接处密封，防止储液单元30的烟液从该连接处的缝隙进入中心通道201内。
安装座20还可包括进气管24和绝缘套25。进气管24安装在第二连接部213上，且内部与中心通孔201连通；该进气管24为导体，用于与电源装置90（如图10所示）电连接；绝缘套25套设在进气管24和第二连接部213之间，将进气管24和第二连接部213隔离。绝缘套25一般为具有弹性的硅胶材质，同时具有密封作用。发热管51上连接的两根电极引线511，一根电极引线511可从进气管24和绝缘套25之间穿出，另一根电极引线511可从绝缘套25和第二连接部213之间穿出，以分别连接电源装置。
优选地，进气管24远离第二连接部213的端部可以开设有通气槽240，防止进气管24的端部与电源装置90（如图10中所示）抵接后，无法进气。
再参考图1、2，在一些实施例中，该电子烟还包括支撑件70和连接件。支撑件70呈环状，设置在安装座20外围并与第一管状结构11的内壁抵接；连接件包括环状的套接部83，套接部83与支撑件70相对应紧箍在壳体10的外侧。
其中，支撑件70位于储液腔31内。壳体10的外侧可以设置有台阶部215，供套接部83卡接，一方面方便连接件定位，确定连接件是否已经位于预设位置，另一方面套接部83的外壁可以与壳体10的外壁共面，使得本体外观平整。连接件可以用于将本体与电子烟的其他部分如电源装置90（如图10所示）连接，支撑件70可以加固连接件与壳体10之间的连接。
支撑件70为刚性的支撑元件，壳体10的第一管状结构11被夹在支撑件70和套接部83之间，套接部83紧箍在第一管状结构11的外侧，套接部83与第一管状结构11的端部紧配，通过支撑件70和套接部83的相互配合，避免第一管状结构11的端部因被长时间挤压而发生变形，使连接件和壳体10的固定连接更加牢靠，不会脱离。支撑件70的硬度一般大于壳体10的硬度。支撑件70优选钢圈，抗烟液腐蚀性较好，钢圈采用型材拉伸形成，而且价格低廉便宜，钢圈容易加工为较薄的结构，例如厚度为0.2mm，钢圈的体积越小，对储液腔31容积的影响就越小。
进一步地，连接件包括第一连接件81和第二连接件82；套接部83设置在第一连接件81上。其中，第一连接件81设置有内螺纹811，第二连接件82设置有与第一连接件81的内螺纹811相适配的外螺纹821，第一连接件81和第二连接件82螺纹连接；第二连接件82还设置有内螺纹822，底座21设置有与第二连接件82的内螺纹822相适配的外螺纹214，第二连接件82和底座21螺纹连接。采用螺纹连接的方式使得组装方便、牢靠且易拆卸。可以理解地，第一连接件81和第二连接件82之间、底座21和第二连接件82之间也可以采用其他连接方式实现，如卡扣、胶粘方式等。
优选地，为确保连接密封性，第一连接件81和第二连接件82之间还可设置有密封圈91，密封圈91位于第一连接件81和第二连接件82螺纹连接位置处，同时与第一连接件81和第二连接件82抵接。第二连接件82和底座21之间也设置有密封圈92。该两处位置可根据需要同时设置密封圈或只一处设置密封圈。具体地，如图2、7所示，底座21的外螺纹214设置在第二连接部213的外周，第二连接件82的内螺纹822位于第二连接件82一端的内周，底座21的主体部212的下端面与第二连接件82的一端端部抵接。密封圈92设置在主体部212的下端面和第二连接部213的夹角处，同时与主体部212、第二连接部213和第二连接件82抵接。
另外，该电子烟还可包括连接在壳体10一端上的电源装置90，该电源装置90与发热元件50电性连接。第二连接件82远离底座21的一端内还可设有内螺纹823（如图2中所示），用于与电源装置90螺纹连接。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
