Description

电子烟 技术领域
本发明涉及一种香烟替代品，更具体地说，涉及一种电子烟。
背景技术
电子烟又名虚拟香烟、电子雾化器。电子烟作为替代香烟用品，多用于戒烟。电子烟具有与香烟相似的外观和味道，但一般不含香烟中的焦油、悬浮微粒等其他有害成分。现有技术的电子烟一般包括筒状壳体，设置于筒状壳体内的雾化组件、电源和储液件，以及封盖于筒状壳体两端部的烟嘴盖和灯盖。该电子烟一定程度上满足了替代香烟用品的功能。然而，现有的电子烟一般通过发热丝加热雾化烟液，由于发热丝能够与烟液接触的面积很小，因此，雾化效率不高。
发明内容
本发明要解决的技术问题在于，提供一种改进的电子烟。
为解决上述技术问题，本发明采用了如下技术方案：提供一种电子烟，包括筒状壳体、烟嘴盖、雾化组件安装座、储液件以及雾化组件，所述烟嘴盖、雾化组件安装座、雾化组件以及储液件均安装于所述筒状壳体的内部，所述雾化组件安装座设置于所述筒状壳体内的中部位置，所述雾化组件设置于所述雾化组件安装座上，并介于所述雾化组件安装座和烟嘴盖之间，所述储液件设置于所述雾化组件外围，所述雾化组件包括通气管、横穿在通气管侧壁中的发热元件，所述发热元件呈条状，该发热元件为泡沫金属发热体、泡沫石墨发热体或多孔陶瓷发热体，所述通气管的侧壁上开设有两个相对的通孔，所述发热元件穿置在两个所述通孔中，且所述发热元件的相对两端露出在所述通气管外；所述通气管的侧壁上还设有切口，所述切口与所述通孔相连通，以供所述发热 元件横向通过至所述通孔中。
本发明的有益效果：通过采用泡沫金属发热体、泡沫石墨发热体或多孔陶瓷发热体作为发热元件，由于泡沫及多孔材料具有很大的比表面积，从而可以增大发热元件与烟液的接触面积，大大提高雾化效率。

具体实施方式
以下结合具体实施例和说明书附图对本发明做进一步详细说明。
图1至图2示出了本发明一些实施例中的电子烟1，其可包括筒状壳体10、烟嘴盖20、灯盖30、雾化组件安装座40、雾化组件50、储液件60、电源70、气流感测器80以及发光件90。
烟嘴盖20和灯盖30分别封盖于筒状壳体10的两端部，雾化组件安装座40、雾化组件50、储液件60以及电源70均位于该筒状壳体10内部。其中，雾化组件安装座40设置于筒状壳体10内的中部位置。雾化组件50设置于雾化组件安装座40上，并介于雾化组件安装座40和烟嘴盖20之间。储液件60设置于雾化组件安装座40上，并包裹在雾化组件50外围。电源70设置于雾化组件安装座40和灯盖30之间，并与雾化组件50电性连接。气流感测器80设置于灯盖30内，发光件90安装于气流感测器80上，气流感测器80及发光 件90均与电源70电性连接。
筒状壳体10可呈圆筒状，其为一个整体，并采用软性塑胶等材料制成，使得使用者施加一定大小的径向力时能够发生弹性变形，以模拟真实香烟的触感。可以理解地，筒状壳体10根据需要也可以呈椭圆筒状或其他筒状构造，并也可以采用钢铁等硬质材料制成。
烟嘴盖20在可采用诸如硅胶等弹性材料制做而成，以便烟嘴盖20能够通过过盈配合的方式紧密地嵌置于筒状壳体10的端部中，防止烟液经过烟嘴盖20与筒状壳体10之间的配合间隙往外渗漏。
灯盖30在可采用硬质塑料一体注塑成型，该灯盖30设置有进气口31。需要说明的是，所述进气口31并不一定要设置在灯盖30上，其也可设置在壳体10上。
雾化组件安装座40用于支撑所述雾化组件50以及储液件60。请参阅图3及图4，雾化组件50在包括通气管51、导液绳52、发热元件53以及定位套筒54。通气管51的进气端用于套接于雾化组件安装座40上，出气端与烟嘴盖20的中心通孔正对。导液绳52可采用玻纤材料制成，其横穿于通气管51的侧壁中，且两端露出在外，该露出的端部与储液件60相连接，以通过毛细力的作用将储液件60中的烟液吸入到通气管51内。发热元件53设置在通气管51内并缠绕在导液绳52上，其主要与导液绳52位于通气管51内部的部分相配合，以通过加热的方式将导液绳52位于通气管51内部的部分上的烟液雾化。定位套筒54套设于通气管51上，且轴向平行通气管51的轴向，为通气管51的特定部位提供结构上的补强。通气管51在可呈细长的圆筒状构造，其可以采用纤维等材料编织制成。通气管51的侧壁上开设有两个相对的通孔510，该通孔510的孔径与导液绳52的直径相适配，以供导液绳52穿置于其中，导液绳52的相对两端露出在通气管51外。为了方便导液绳52的穿置，通气管51的侧壁上还设有切口512，切口512与通孔510相连通，以供导液绳52横向通过至通孔510中。在一些实施例中，切口512在通气管51上位于通孔510上方的位置。
如图5所示，该切口512能够让通气管51被该切口512切开的两部分被 扳开一定的角度，使得闭合的通孔510上形成一个具有一定宽度的开口，让导液绳52能够横向放入到该通孔510中，免去了穿孔安装的麻烦，很大程度上方便了导液绳52的安装。该切口512在一些实施例中可包括在通气管51上由外向内延伸的横切段5121以及与横切段5121相连接的纵切段5123，该纵切段5123延伸至该两个通孔510中。横切段5121与纵切段5123的夹角优选地为钝角，可以理解地，当该夹角为直角时也可以。
由于通气管51上切口512的设置，使得通气管51的强度有较大程度上的下降，当受到外力(例如，外围的储液件60的压力)的作用下，通气管51出现在切口512处塌陷的概率大幅度增加。为了克服该问题，本发明一些实施例提供了定位套筒54，该定位套筒54可套接于通气管51上该切口512所在的位置，以将外界施加在通气管51上切口512所在的位置的力分散到通气管51的其他部位，从而降低外力对通气管51上切口512所在的位置处应力集中。定位套筒54的材质可与通气管51的材质相同，其内径与通气管51的外径相当，长度大于与切口512在通气管51纵向上的最大长度。如此，该定位套筒54能够紧密地套接在通气管51上，并完全包覆住切口52，使得该通气管51的整体抗外力能力大幅度提升。
所述发热元件53可为金属发热丝，其缠绕在导液绳52位于通气管51内部的部分上，以对导液绳52位于通气管51内部的部分中的烟液进行加热雾化。请参阅图6，为了能够增大发热元件53与导液绳52的接触面积，以提高雾化效率，本实施例中，所述金属发热丝表面形成有很多凸起531，可以理解，所述凸起531的形状可以是圆形、椭圆形、方形、三角形等等，只要能够增大发热元件53与导液绳52的接触面积即可。
请参阅图7，为本发明第二实施例的电子烟中的发热元件的示意图。所述第二实施例的电子烟与上述第一实施例中的电子烟1基本相同，区别仅在于，使用多孔发热管53a代替第一实施例中的发热丝，即多孔发热管53a套设在纤维绳52外，该多孔发热管53a侧壁上开设有多个贯穿孔531a，其中心孔532a用于收容纤维绳52。通过采用多孔发热管53a，可以大大增加与纤维绳52的接触面积，从而提高雾化效率。优选的，所述多孔发热管53a完全位于通气管 51的气流通道中。
请参阅图8，在一些实施方式中，还可以将第一实施例中的电子烟1中的纤维绳52及发热丝替换为由柔性发热条和耐温棉编织成的柔性发热体53b，该柔性发热体53b呈条状，横跨在通气管上。所述柔性发热体53b也可替换为泡沫金属发热体、泡沫石墨发热体或多孔陶瓷发热体，该等发热体均可增大与烟液的接触面结，具有更好的雾化效率。
储液件60可以采用储液棉片卷曲而成。储液件60包裹在雾化组件50的外围，并与雾化组件50的导液绳52紧密贴合，使得储液件60中的烟液能够在导液绳52的毛细力的作用下，不停地往通气管51内部传递。
电源70在一些实施例中可包括柱状软包锂电池，其与筒状壳体10的内壁面之间形成有间隙，以供空气流通。气流感测器80在一些实施例中可呈扁圆柱状，该气流感测器80安装于灯盖30内，并与灯盖30的内壁面过盈配合。发光件90可以为LED发光二极管，其设置于气流感测器80与灯盖30相对的表面上。
应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干个改进和润饰，这些改进和润饰也应视为本发明的保护范围。
