<导液元件>
本发明中导液元件200由纤维粘结制成,可以用粘结剂粘结纤维制成导液元件200,也可以用热粘结纤维的方法制成导液元件200。
导液元件200的密度为0.1克/厘米
3至0.35克/厘米
3,优选为0.15克/厘米
3至0.25克/厘米
3。当密度小于0.1克/厘米
3时,导液元件200的强度不足,不易组装。当密度大于0.35克/厘米
3时,液体传导速度较慢,影响雾化性能。
导液元件200的厚度为0.3mm至3mm,如0.3mm、0.5、0.8mm、1.0mm、1.2mm、1.5mm、2mm、2.5mm、3mm。优选导液元件200的厚度为0.6至1.5mm。当导液元件200的厚度小于0.3mm时,导液元件200的强度不足,不易安装。当导液元件200的厚度大于3mm时,导液元件200吸收液体的量过多,影响液体的利用效率。
导液元件200通常设计为片状。根据储液元件100的结构和形状可以把导液元件200设计成圆形、方形、椭圆形、圆环形、椭圆环形或其它需要的形状。导液元件200可以设置有贯穿导液元件200的通孔230,并形成导液元件200的内周壁。
<纤维>
制成导液元件200的纤维可以为玻璃纤维、陶瓷纤维或聚合物纤维。纤维可以为长丝或短纤。陶瓷纤维和玻璃纤维较脆,制成的导液元件200容易碎裂或产生碎屑,优选聚合物纤维,最优选皮芯结构或并列结构的双组分聚合物纤维。

本实施例的导液元件200优选由皮芯结构的双组分纤维2热粘结制成。双组分纤维2的皮层可以为聚乙烯、聚丙烯等聚烯烃,也可以为聚酰胺、聚酯或低熔点共聚酯等常见的聚合物。芯层可以为聚丙烯、聚酰胺、聚对苯二甲酸乙二醇酯(简称PET)等聚合物。
制作本发明导液元件200的双组分纤维2的纤度介于1至30旦,优选1.5至10旦。低于1旦的皮芯结构双组分纤维2制造困难,成本高。高于30旦的纤维制成的导液元件200毛细力不足,导液较差。介于1至30旦的皮芯结构双组分纤维2容易制作导液元件200,1.5至10旦皮芯结构双组分纤维2尤为合适,并且成本较低。
<储液元件>
在本实施例中,储液元件100包括储液元件壳体110、在储液元件壳体110内形成的储液部101和容纳在储液元件壳体110中的导液元件200。
储液部101为储液元件100中储存液体的部位。可以让导液元件200的一侧接触储液部101中的液体,从而使得导液元件200与储液部101连通。
在本实施例中,储液元件壳体110内形成的储液部101具有贯穿储液部101的储液元件通孔130,储液元件壳体110包括储液元件通孔130的壁部。储液元件通孔130包括气雾出口1301、雾化芯连接口1302以及连通雾化芯连接口1302和气雾出口1301的气雾通道1303。
在本实施例中,导液元件200优选为圆环形的片状体,并设置有贯穿导液元件200的通孔230。导液元件200靠近雾化芯连接口1302的附近,导液元件200的内周壁与储液元件通孔130的壁部紧密装配。
在本实施例中,储液元件100还包括雾化室934和缓冲室953。储液元件壳体110远离气雾出口1301的一端设置有储液元件壳体底部密封部112,导液元件200和储液元件壳体底部密封部112的中间的凹陷部分构成雾化室934。储液元件壳体110、导液元件200和储液元件壳体底部密封部112上部外侧的凹陷部分构成缓冲室953。储液元件壳体110的内壁与导液元件200的外周壁或外周壁的局部设置间隙D。在本实施例中,间隙D的最大内切圆直径介于0.02mm到0.25mm,间隙D将缓冲室953与储液部101连通。
储液元件壳体底部密封部112还可以设置有贯穿储液元件壳体底部密封部112的密封部通孔1122,密封部通孔1122与雾化室934连通,且优选为与气雾通道1303同轴设置。密封部通孔1122远离气雾通道1303的端部入口设置为密封部进气口1121,用于向雾化室934输送空气。
在本实施例中,储液元件100还包括雾化芯930,导液元件200的一侧接触储液部101中的液体,液体经导液元件200传递给雾化芯930。雾化芯930包括导液芯932和缠绕在导液芯932上的发热体931。储液元件100还包括导线933和导线引脚936,导线933连接发热体931和导线引脚936。导液芯932由储液元件壳体底部密封部112所支撑,并使得导液芯932两端的弯折部分基本与导液芯932未弯折的部分的夹角大于或者等于90度。导液芯932弯折部分的两端与导液元件200抵接,由此接受经导液元件200传递的液体。
当导液元件200中液体含量较高时,间隙D中充满液体。使用时,雾化芯930上的液体被雾化消耗,储液部101中的液体经导液元件200传导给雾化芯930,储液部101中负压增加,使导液元件200中液体含量减少,间隙D中的液体被导液元件200部分吸收,外界空气可以通过间隙D进入储液部101,使储液部101中负压减小,导液元件200中液体含量增加,间隙D中重新充满液体。
经雾化芯930雾化的气雾经雾化芯连接口1302、气雾通道1303和气雾出口1301逸出,上述过程在液体雾化时反复进行直到液体被用完。
通过设置间隙D的大小,可以控制储液元件100的气液交换,从而满足不同气雾散发装置的性能要求。由于导液元件200内部具有三维网络结构,并形成大量互相连通的毛细通道,这种毛细通道有利于液体在其中快速、平稳地传导,从而实现灵敏快速的气液交换,提高雾化的稳定性。当间隙D较大时,储液部101中较小的负压即可让外界空气补充进入储液部101,适合于气雾量较大的气雾散发装置。当间隙D较小时,储液部101中较大的负压才能让外界空气补充进入储液部101,适合于较小气雾量的气雾散发装置。异常情况下,如温度升高或外界压力降低,储液部101内的空气膨胀,储液部101中的部分液体从间隙D溢出进入缓冲室953,避免储液元件100中的液体向外部泄漏。
在本实施例中,优选间隙D的最大内切圆直径为0.05mm至0.15mm,并优选导液元件200的厚度为0.8mm至1.2mm、优选导液元件200的密度为0.15克/厘米
3至0.25克/厘米

在本实施例中,储液元件100还设置有定位板114,定位板114设置有多个孔隙或者镂空,并用来对导液元件200定位,并增加对导液元件200的支撑。多个空隙或者镂空用于传导液体。定位板114设置在导液元件200与储液部101中液体接触的一侧。
在本实施例中,导液元件200外周壁的局部与储液元件壳体110之间设置间隙D,间隙D可以是由储液元件壳体110的内周壁上进行局部切割形成的凹陷部分,如图2b所示;或由导液元件200外周壁上进行局部切割形成,如图2c所示。和第一实施例相比,在间隙D的内切圆直径d相同的情况下,第二实施例中间隙D的总面积大幅度下降,这样能大幅降低漏液的风险。
在第二实施例中,储液元件壳体底部密封部112由硅胶制成,储液元件壳体底部密封部112的上部形成斜向设计,方便雾化芯930的安装并对雾化芯930形成有效支撑。

当本实施例的储液元件100用于粘度较低的电子烟液或药物溶液雾化时,可以设置较小的间隙D,其内切圆直径d可以在0.02mm至0.1mm之间;当本实施例的储液元件100用于粘度较高的电子烟液、大麻二酚溶液或药物溶液雾化时,可以设置较大的间隙D,其内切圆直径d可以在0.1mm至0.25mm之间。第二实施例的储液元件100工作原理与第一实施例相似。

如图3a所示,导液元件200的一侧接触储液部101中的液体,另一侧接触雾化芯930的多孔陶瓷937,储液部101中的液体经导液元件200传递给多孔陶瓷937,再从多孔陶瓷937的一侧渗透到另一侧,由发热体931进行雾化。也可以在导液元件200上设置通孔,使储液部101中的液体直接接触雾化芯930的多孔陶瓷937,液体渗透多孔陶瓷937后在另一侧进行雾化。
在本实施例中,储液元件壳体110包括储液部101的壁部,气雾通道1303由储液部101壁部和储液元件壳体110的外周壁之间的腔道形成,即气雾通道1303设置在储液部101的外侧。雾化室934由储液元件壳体底部密封部112、导液元件200以及储液元件壳体110限定的空间形成,雾化室934兼具缓冲室953的功能。第三实施例的储液元件100工作原理与第一实施例相似。

如图4a所示,在本实施例中,雾化芯930的一侧直接接触储液部101中的液体,也就是多孔陶瓷937的一侧直接接触储液部101中的液体。液体渗透多孔陶瓷后在另一侧进行雾化,同时,雾化芯930的多孔陶瓷937的外侧也与导液元件200抵接,接收来自导液元件200传送的液体。
气雾经位于储液元件100前后两侧的气雾通道1303汇聚到储液元件100中上部中间的气雾通道1303,并经气雾出口逸出。本实施例中雾化室934兼具缓冲室953的功能。
在本实施例中,储液元件壳体底部密封部112的底部还设置有密封部磁吸1124,用于储液元件100与气雾散发装置之间的装配。
第四实施例的储液元件100工作原理与第一实施例相似。
第五实施例
图5a为本发明所公开的第五实施例的储液元件100的纵剖面示意图,图5b是图5a在A-A处的横截面示意图。本实施例与第一实施例结构相似,与第一实施例相同的部分在本实施例的描述中不再赘述。
不同在于,如图5a和5b所示,本实施例中,导液元件200形状为圆环形,导液元件200设置通孔并形成导液元件200的内周壁。储液元件壳体110内形成的储液部101具有贯穿储液部101的储液元件通孔130,储液元件壳体110包括储液元件通孔130的壁部。储液元件通孔130包括气雾出口1301、雾化芯连接口1302以及连通雾化芯连接口1302和气雾出口1301的气雾通道1303。
导液元件200的内周壁与储液元件通孔130的外壁之间设置间隙D。在本实施例中,具体为,导液元件200的内周壁与雾化芯连接口1302的外壁之间设置间隙D,导液元件200的外周壁与储液元件壳体110之间紧密装配,间隙D的内切圆直径d介于0.02mm至0.25mm,可以根据需要调整d的大小以适合不同粘度的液体。
本实施例中,雾化芯930包括导液芯932和缠绕在导液芯932上的发热体931。导线933连接发热体931和导线引脚936。导液芯932由储液元件壳体底部密封部112所支撑,并使得导液芯932两端的弯折部分基本与导液芯932未弯折的部分的夹角大于90度。导液芯932弯折部分的两端与导液元件200抵接,由此接受经导液元件200传递的液体。导 液芯932优选为玻纤束或棉纤束。
在本实施例中,储液元件壳体110内形成的储液部101具有贯穿储液部101的储液元件通孔130,储液元件壳体110包括储液元件通孔130的壁部。储液元件通孔130包括气雾出口1301、雾化芯连接口1302以及连通雾化芯连接口1302和气雾出口1301的气雾通道1303。雾化芯连接口1302的内径大于气雾通道1303的内径,由此有利于雾化室934中产生的气雾可以更顺畅地进入气雾通道1303。
如图5a所示,本实施例中,储液部101中的液体经导液元件200传导给导液芯932后进行雾化,气雾经气雾通道1303逸出。第五实施例的储液元件100工作原理与第一实施例相似。
综上,本发明涉及的储液元件构思独特,结构简单,能广泛应用于各类气雾散发装置。导液元件内部具有大量互相连通的毛细通道,有利于液体在其中快速传导,从而实现灵敏快速的气液交换,使雾化顺畅稳定。通过设置间隙D的大小,可以控制不同应用需求下储液元件的气液交换,从而满足不同气雾散发装置的性能要求。
