具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
图 1 示出了本发明较佳实施例之一提供的一种 电子烟 , 所述电子烟包括电子烟本体,电子烟本体设置有吸烟端 1 、用于存储烟油的油杯组件 2 、用于雾化烟油的雾化芯 3 、 用于为雾化芯 3 供电的电池杆 4 和供气流流通的气流通道 5 ,气流通道 5 沿电子烟本体的轴向开设,并与吸烟端 1 相导通,图示箭头为电子烟本体内气流的流动方向。
结合图 2 所示, 油杯组件 2 设置有储油套 21 ,储油套 21 内形成有用于存储烟油的储油腔 23 ,储油套 21 的一端为与储油腔 23 相连通的开口端,雾化芯 3 穿过 该 开口端可拆卸的插设在油杯组件 2 内;
结合图 3 所示, 雾化芯 3 包括雾化套 31 ,雾化套 31 延伸至储油套 21 外的一端与电池杆 4 可拆卸的连接,雾化套 31 内形成有雾化腔 33 ,雾化腔 33 内收容有电热丝组件 34 ;雾化套 31 的一端设有分别与电池杆 4 和电热丝组件 34 电连接的电连接组件 。当然,在其它实施例中,也可以将所述 雾化套 31 设置成两个套体,其中一个套体用于收容所述电热丝组件 34 ,而另一个套体的两端分别与所述 电池杆 4 及用于收容所述电热丝组件 34 的所述套体的一端 可拆卸的连接 。因而,所述 雾化套 31 的结构在此不作具体限定。
其中, 电连接组件包括由内到外依次套设相连的内电极 35 、绝缘套 36 和外电极 37 ;结合图 6 所示, 绝缘套 36 朝向雾化腔 33 的一端设有通气孔 361 ,通气孔 361 上活动盖设 有与所述 绝缘套 36 一体成型的 阻挡薄膜 362 ,以使当气流从吸烟端 1 流向雾化腔 33 时,气流推动阻挡薄膜 362 封堵 所述 通气孔 361 (结合图 7 所示) ,当气流从雾化腔 33 流向吸烟端 1 时,气流推动阻挡薄膜 362 导通所述通气孔 361 (结合图 6 所示) 。
本实施例中,由于绝缘套 36 朝向雾化腔 33 的一端设置有通气孔 361 和活动盖设在该通气孔 361 上的阻挡薄膜 362 ,且阻挡薄膜 362 在气流的推动下封堵或导通通气孔 361 ,使得绝缘套 36 和阻挡薄膜 362 形成一单向阀,这样当用户朝电子烟内吹气时,气流推动阻挡薄膜 362 盖设在通气孔 361 上,使得气流无法通过电极通气道 351 (如图 3 所示),则气流可能带动的烟油可无法穿过电极通气道 351 进入到电池杆 4 内,从而避免电池杆 4 内的气流感应器(图上未标号)和电池 42 被烟油损坏,提高了产品的使用寿命。
此外,通过在绝缘套 36 上设置通气孔 361 和与所述绝缘套 36 一体成型的阻挡薄膜 362 ,来形成上述单向阀,不需要额外在气流通道 5 上安装独立的气流限制部件 来防止烟油进入到电池杆 4 内 , 本申请电子烟不仅结构简单,还 简化了电子烟的装配过程,节约了制造成本。
结合图 3 和图 4 所示的实施例对雾化芯 3 的具体结构进行详细说明。
雾化芯 3 的两端分别与 油杯组件 2 和电池 杆 4 可拆卸的连接,该可拆卸连接的结构可以为螺纹连接结构或卡扣连接结构 等 ,本实施例中,雾化芯 3 与 油杯组件 2 和电池 杆 4 之间的连接均为螺纹连接。
如图 3 所示,雾化芯 3 主要包括雾化套 31 、雾化盖 3 2 、雾化腔 3 3 、电热丝组件 3 4 和电连接组件。
其中,电连接组件包括由内到外依次套设相连的 内电极 35 、 绝缘 套 36 和外电极 37 ,内电极 35 开设有贯穿内电极 35 两端用于供气流流通的电极通气道 351 ,该电极通气道 351 与通气孔 361 相导通。进一步的,内电极的外周面与通气孔 361 的内壁弹性抵接,电极通气道 351 位于通气孔 361 内, 以使吸烟时气流从 通气孔 361 内的 电极通气道 351 进入雾化腔 33 内, 当气流从吸烟端 1 流向雾化腔 33 时,气流推动阻挡薄膜 362 抵接至内电极 35 端面 从而封堵通气孔 361 及 电极通气道 351 。 当然,也可以在 绝缘 套 36 的位于所述通气孔 361 的孔壁处凸设有阻挡部或设置所述 阻挡薄膜 362 的面积大于所述 通气孔 361 的面积,从而使 当气流从吸烟端 1 流向雾化腔 33 时,气流推动阻挡薄膜 362 抵接至 所述阻挡部或所述绝缘套 36 的端面 从而封堵通气孔 361 及 电极通气道 351 。其具体结构,在此不作具体限定。
结合图 6 所示,绝缘套 36 大致为中空的柱体结构,绝缘套 36 朝向雾化腔 33 的一侧设置有通气孔 361 和阻挡薄膜 362 ,阻挡薄膜 362 活动盖设在通气孔 361 上,且阻挡薄膜 362 与绝缘套 36 为一体成型结构。本实施例中阻挡薄膜 362 为圆形结构,阻挡薄膜 362 的一端为固定端,其固定在通气孔 361 的周缘,阻挡薄膜 362 的另一端为自由端。阻挡薄膜 362 和通气孔 361 共同组成一单向阀,当 气流从吸烟端 1 流向雾化腔 33 时, 气流推动阻挡薄膜 362 的自由端,使阻挡薄膜 362 抵接至内电极 35 从而封堵通气孔 361 ,以将单向阀关闭;当气流从雾化腔 33 流向吸烟端 1 时,气流推动阻挡薄膜 362 的自由端将通气孔 361 导通,从而将单向阀打开。
吸烟时,气流从电极通气道 351( 如图 3 所示 ) 中通过,并将阻挡薄膜 362 向上掀起,气流往上运动被用户吸食,电子烟正常工作;当电子烟不工作时,阻挡薄膜 362 盖设在通气孔 361 上,从而避免烟油经过通气孔 361 和电极通气道 351 流入电池杆 4 内。本实施例通过在绝缘套 36 上设置一单向阀,可以有效避免烟油通过电极通气道 351 进入电池杆 4 内。
可以理解的是,在其它实施例中,阻挡薄膜 362 还可以采用其它方式连接在通气孔 361 的周缘上,只要其能使阻挡薄膜 362 和通气孔 361 共同组成一单向阀,并使得 当气流从吸烟端 1 流向雾化腔 33 时,气流推动阻挡薄膜 362 封堵 所述 通气孔 361 ,当气流从雾化腔 33 流向吸烟端 1 时,气流推动阻挡薄膜 362 导通所述通气孔 361 即可。此外,所述阻挡薄膜 362 的厚度及大小可根据需要进行设置,在此不作具体限定。
本实施例中,雾化套 31 即为 电连接组件的 外电极 37 ,而绝缘套 36 和内电极 35 依次套设在雾化套 31 内,电热丝组件 34 通过该雾化套 31 和内电极 37 与电池杆 4 电连接。可以理解的是,在其它实施例中,雾化套 31 可以不为外电极 37 ,即雾化套 31 由绝缘材料制成,外电极 37 、绝缘套 36 和内电极 35 依次套设在雾化套 31 内。本实施例并不限制内电极 35 和外电极 37 的具体结构,只要其能分别与电热丝组件 34 和电池杆 4 电连接即可。
如图 3 所示,电热丝组件 34 包括 导油件 3 4 1 和电热丝 3 4 2 ,导油件 3 4 1 由吸油材料制成,其固定在 雾化套 31 的 安装槽 311 (结合图 4 所示) 的底部,且导油件 3 4 1 的两端分别延伸至储油腔 21 内,电热丝 3 4 2 缠绕在该导油件 3 4 1 上,并与电池 杆 4 电连接。
具体的,电热丝 342 的一端延伸至雾化套 31 与绝缘套 36 之间,并与外电极 37 电连接,电热丝 342 的另一端穿过绝缘套 36 与内电极 35 电连接。本实施例中,雾化套 31 的内表面与绝缘套 36 的周向外表面过盈配合并夹紧电热丝 342 的一端,使得电热丝 342 的一端与雾化套 31 电连接;电热丝 342 的另一端从通气孔 361 与阻挡薄膜 362 的缝隙中穿过,并延伸至绝缘套 36 与内电极 35 之间,绝缘套 36 的内表面与内电极 35 的周向外表面过盈配合并夹紧电热丝 342 的另一端,使得电热丝 342 的另一端与内电极 35 电连接。
结合图 4 所示,雾化套 31 的一端与储油套 21 可拆卸的连接,另一端与电池杆 4 可拆卸的连接。具体的,雾化套 31 包括大致为中空柱体结构的主体 310 ,主体 310 上设有安装槽 311 、气孔 312 、限位卡台 313 、环形凹槽 314 、凸起 316 和限位凸部 317 。
安装槽 311 开设在主体 310 靠近 吸烟端 1 的一端,并朝远离 吸烟端 1 的一侧延伸。本实施例中,安装槽 311 包括两个,两个安装槽 311 相对间隔设置并与储油腔 23 相连通,电热丝组件 34 的导油件 341 架设并固定在所述两个安装槽 311 的底部。
气孔 312 设在主体 310 延伸至 储油套 2 1 外的一端上,并与雾化腔 3 3 相导通,气孔 312 主要用以进气及排除雾化腔 3 3 内的烟油。由于气孔 312 位于储油套 2 1 外,故气流直接通过该气孔 312 即可进入雾化腔 3 3 内,不会产生噪音。
限位卡台 313 凸设在主体 310 的外壁上,其可以避免雾化芯 3 在组装的过程中,储油套 21 将气孔 312 堵塞。具体的,雾化芯 3 在组装过程中,该限位卡台 313 抵接至储油套 21 的端口侧缘,由于气孔 312 位于限位卡台 313 远离吸烟端 1 的一侧,从而可以避免气孔 312 在组装过程中被堵塞。
优选地,为了避免烟油从主体 310 与 储油套 21 的连接处泄漏,可以在主体 310 上套设密封件(图上未标号)。具体的,本实施例中,主体 310 位于 储油套 21 内的外周壁上设有环形卡槽 314 ,密封件固定在该环形卡槽 314 内并弹性抵接至储油套 21 的内壁,以实现密封作用。
优选地,为了更好的支撑电热丝组件 34 ,主体 310 上设置有用于支撑电热丝组件 34 的凸起 316 ,该凸起 316 的一端固定在安装槽 311 的底部,另一端朝远离主体 310 的轴线方向延伸。通过设置凸起 316 ,可以避免支撑电热丝组件 34 的侧壁过薄而使电热丝组件 34 滑入雾化腔 33 内。

其中,阻挡薄膜 362 的一端为固定端,其固定在通气孔 361 的周缘,阻挡薄膜 362 的另一端为自由端。 当气流从吸烟端 1 流向雾化腔 33 时,气流推动阻挡薄膜 362 封堵 所述 通气孔 361 (结合图 8 所示) ,当气流从雾化腔 33 流向吸烟端 1 时,气流 从阻挡薄膜 362 与通气孔 361 的缝隙 363 中穿过,并 推动阻挡薄膜 362 导通所述通气孔 361 (结合图 9 所示) 。
进一步的,穿孔 364 主要用于供电热丝组件 34 的电热丝 342 穿设,其开设在绝缘套 36 朝向雾化腔 33 的一端面上,电热丝 342 的一端穿过该穿孔 364 与内电极 35 电连接。具体的,雾化套 31 的内表面与绝缘套 36 的周向外表面过盈配合并夹紧电热丝 342 的一端,使得电热丝 342 的一端与雾化套 31 电连接;电热丝 342 的另一端从 穿孔 364 中穿过,并延伸至绝缘套 36 与内电极 35 之间,绝缘套 36 的内表面与内电极 35 的周向外表面过盈配合并夹紧电热丝 342 的另一端,使得电热丝 342 的另一端与内电极 35 电连接。
图 10 示出了本发明较佳实施例之三提供的一种电子烟,其与实施例二的不同之处在于 绝缘套 36 上穿孔 364 的开设位置 。
结合图 10 所示,绝缘套 36 大致为中空的柱体结构,绝缘套 36 朝向雾化腔 33 的一侧设置有通气孔 361 、与所述绝缘套 36 一体成型的阻挡薄膜 362 和穿孔 364 。
其中,阻挡薄膜 362 的一端为固定端,其固定在通气孔 361 的周缘,阻挡薄膜 362 的另一端为自由端。
进一步的,穿孔 364 主要用于供电热丝组件 34 的电热丝 342 穿设,其开设在绝缘套 36 的侧壁上,电热丝 342 的一端穿过该穿孔 364 与内电极 35 电连接。

结合图 11 和 12 所示,绝缘套 36 大致为中空的柱体结构,绝缘套 36 朝向雾化腔 33 的一侧设置有通气孔 361 、与所述绝缘套 36 一体成型的阻挡薄膜 362 和穿孔 364 。
其中, 阻挡薄膜 362 具有若干个, 阻挡薄膜 362 位于 绝缘套 36 的端面上 ,阻挡薄膜 362 之间形成 有缝隙 363 ,阻挡薄膜 362 自由端的端部位于 通气孔 361 的中轴线上或位于 通气孔 361 的中轴线周围,阻挡薄膜 362 固定在通气孔 361 上,且该阻挡薄膜 362 上开设有缝隙 363 。本实施例中, 阻挡薄膜 362 具有四个, 所述 两 缝隙 363 之间形成的夹角为 90 度。由于设置有多个所述 阻挡薄膜 362 ,因而单个 阻挡薄膜 362 可以设计较小,从而可解决仅设置一个 阻挡薄膜 362 而导致容易疲劳的问题,且即使某个 阻挡薄膜 362 失效,其余的 阻挡薄膜 362 也会实现相应的功能,从而提高了产品的使用寿命。
当气流从吸烟端 1 流向雾化腔 33 时,气流推动阻挡薄膜 362 封堵 所述 通气孔 361 (结合图 11 所示) ,当气流从雾化腔 33 流向吸烟端 1 时,气流 从缝隙 363 中穿过,并 推动阻挡薄膜 362 导通所述通气孔 361 (结合图 12 所示) 。
进一步的,穿孔 364 主要用于供电热丝组件 34 的电热丝 342 穿设,其开设在绝缘套 36 朝向雾化腔 33 的一端面上,电热丝 342 的一端穿过该穿孔 364 与内电极 35 电连接。
图 13 和 14 示出了本发明较佳实施例之五提供的一种电子烟,其与实施例四的不同之处在于 绝缘套 36 的不同 。
结合图 11 和 12 所示,绝缘套 36 大致为中空的柱体结构,绝缘套 36 朝向雾化腔 33 的一侧设置有通气孔 361 、与所述绝缘套 36 一体成型的阻挡薄膜 362 和穿孔 364 。
其中, 阻挡薄膜 362 具有若干个, 阻挡薄膜 362 位于 绝缘套 36 的端面上 ,阻挡薄膜 362 之间形成 有缝隙 363 ,阻挡薄膜 362 自由端的端部位于 通气孔 361 的中轴线上或位于 通气孔 361 的中轴线周围,阻挡薄膜 362 固定在通气孔 361 上,且该阻挡薄膜 362 上开设有缝隙 363 。本实施例中, 阻挡薄膜 362 具有三个, 所述 两 缝隙 363 之间形成的夹角为 120 度。
当气流从吸烟端 1 流向雾化腔 33 时,气流推动阻挡薄膜 362 封堵 所述 通气孔 361 (结合图 13 所示) ,当气流从雾化腔 33 流向吸烟端 1 时,气流 从缝隙 363 中穿过,并 推动阻挡薄膜 362 导通所述通气孔 361 (结合图 14 所示) 。
进一步的,穿孔 364 主要用于供电热丝组件 34 的电热丝 342 穿设,其开设在绝缘套 36 朝向雾化腔 33 的一端面上,电热丝 342 的一端穿过该穿孔 364 与内电极 35 电连接。
综上所述 ,实施本发明的电子烟,具有以下有益效果:
( 1 )由于绝缘套朝向雾化腔的一端设置有通气孔和活动盖设在该通气孔上的阻挡薄膜,从而形成一单向阀,这样当用户朝电子烟内吹气时,气流推动阻挡薄膜盖设在通气孔上,使得气流无法通过电极通气道,则气流可能带动的烟油可无法穿过电极通气道进入到电池杆内,从而避免电池杆内的气流感应器和电池被烟油损坏,提高了产品的使用寿命。
( 2 )通过在绝缘套上设置通气孔和与所述绝缘套一体成型的所述阻挡薄膜,来形成上述单向阀,不需要额外在气流通道上安装独立的气流限制部件来防止烟油进入到电池杆内,本申请电子烟不仅结构简单,还简化了电子烟的装配过程,节约了制造成本。
( 3 )雾化芯的雾化盖内设置有密封环,通气管与密封环连接时,一直保持有相互挤压的弹性作用力,这样可以使雾化芯与通气管的连接更加紧密,从而防止烟油流入至通气管内,避免用户吸食到烟油。
( 4 ) 储油套 由可透光的材料制得,可以方便用户查 看 储油腔内烟油的余量。
( 5 )雾化芯与油杯组件为可拆卸连接的结构,方便用户更换已经损坏的雾化芯,避免资源浪费。
虽然本发明是通过具体实施例进行说明的,本领域技术人员应当明白,在不脱离本发明范围的情况下,还可以对本发明进行各种变换及等同替代。另外,针对特定情形或材料,可以对本发明做各种修改, 例如, 阻挡薄膜 362 还可以采用粘接、铰接等其它方式连接在通气孔 361 的周缘上等均 不脱离本发明的范围。因此,本发明不局限于所公开的具体实施例,而应当包括落入本发明权利要求范围内的全部实施方式。
