Description

可回收冷凝液的电子烟雾化芯及电子烟 技术领域
本公开属于电子烟领域，具体涉及一种可回收冷凝液的电子烟雾化芯及电子烟。
背景技术
在市场上的主流电子烟雾化器为两大类：多孔陶瓷基嵌埋金属发热丝、金属薄片或印刷厚膜电阻制成的以多孔陶瓷为导油储油的陶瓷雾化器；一类是以棉为导油储油材料的棉绕丝雾化器。
对于采用陶瓷雾化器的烟弹结构，雾化器蒸发面向下，与进气流正面对冲，蒸发的气溶胶从雾化器侧面进入气流通过，产生的冷凝液会聚集到烟弹底部，可能会通过进气孔产生漏油。
对于采用棉绕丝雾化器的烟弹，蒸发面和吸气管直通相连，部分冷凝液可以回流到储油棉，但是棉芯的不足就是高温会有烧糊的问题。
随着人们对抽烟引起的自身健康及环境污染问题关注。作为香烟的减害替代品电子烟受到越来越多的消费者的青睐。然而市场上的电子烟产品仍存在冷凝液泄漏问题，给消费者带来不良体验。雾化效率低和冷凝液问题是目前电子烟行业的技术关注点。特别是冷凝液一方面在吸气管内壁聚集会吸入口中，造成不良体验。另一方面冷凝液汇集多了会顺气流通道从吸气口或进气口流出造成漏液。
对于目前雾化膏状烟油，基于膏状烟油在常温下流动性差，造成供油不足问题。雾化器的设计大都采用预热功能，使用前先对膏状烟油预热是其粘度降低达到可流动状态，然后再进行抽吸。预热功能一般采用另外设置的预热电路，设计复杂，消耗电池功率。

以下通过具体实施例结合附图对本公开的技术方案做进一步阐述说明。需要注意的是，下述的具体实施例仅是作为举例说明，本公开的保护范围并不限于此。
如图1所示，本实施例公开了一种可回收冷凝液的陶瓷雾化芯，该陶瓷雾化芯由微孔陶瓷管1和电热雾化元件2通过热浆高压灌注成型，后经高温烧结成为一体。所述电热雾化元件2为焊接电极引线3的多孔金属纤维毡片。微孔陶瓷管1的中心沿轴线方向设有通气孔，上段收口为烟道4，下段为雾化腔5。焊接电极引线3的多孔金属纤维毡片过微孔陶瓷管1的轴心并垂直微孔陶瓷管1的轴线，横向安置在微孔陶瓷管1内部，过通气孔部分悬空，与烟道气流方向(图1中箭头A指示的方向)相交，其余部分和两个电极引线竖直嵌埋在微孔陶瓷管1壁内。
本实施例中陶瓷雾化芯的雾化界面由悬空的多孔金属纤维毡片和嵌埋了多孔金属纤维的微孔陶瓷管1内壁两部分组成。烟油从微孔陶瓷管1基体的外部渗透至微孔陶瓷管1的内部和多孔金属纤维片上，通过两电极引线3对多孔金属纤维毡片供电，多孔金属纤维具有一定的电阻，通电后发热，并加热自身多孔材质内存储的烟油，烟油受热后发生相变，雾化形成气溶胶烟雾，同时嵌埋在微孔陶瓷的金属纤维也会把热量传导给微孔陶瓷，使微孔陶瓷加热烟油产生雾化效果，产生的气溶胶经雾化腔5流经烟道4被吸进入口腔中。多孔金属纤维毡既可发热雾化烟油也可导油储油，增大雾化效率。陶瓷雾化芯上部和吸气管相连，工作时吸气管内产生的冷凝液回流到微孔陶瓷管1内壁，在加热雾化时被重新回收利用。
所述的微孔陶瓷管1，是带收口的柱体，可以是圆柱、椭圆柱体、长方体、三角柱等，但不仅限于此。微孔陶瓷管1上段收口，收口内径与吸气管匹配。这个微孔陶瓷管1可有效回收冷凝液。微孔陶瓷管1作为导油和储油器件。所用材料是食品接触级结构陶瓷材料，如氧化铝、 氧化锆、碳化硅等，由单一或复合氧化物或非氧化物组成。微孔陶瓷的孔隙直径大小范围为3微米～100微米，微孔陶瓷的孔隙率为30％～70％。
所述电热雾化元件是多孔金属纤维，金属纤维主材料是金属纤维组成(金属纤维包括但不仅限于：不锈钢金属纤维、铁铬铝金属纤维、钛镍金属纤维、镍金属纤维、哈氏合金纤维、其他导电金属纤维等)。材料是经过短切、铺装、层压、高温烧结工艺而形成的多孔金属纤维毡。所形成的孔隙都是通孔，可以避免因液体干烧而形成的堵孔现象。
金属纤维毡的单丝直径范围为2-50微米。
金属纤维毡的厚度范围为0.1-1毫米。
金属纤维毡的孔隙直径范围为3-100微米。
金属纤维毡的孔隙率的范围为30％～98％。
金属纤维毡具有很高的空隙率，且都为开孔。金属纤维可以使电子烟油360°包裹，从而增加发热体与电子烟油充分的比表面积，缩短了雾化热传输途径，使热量集中用于雾化烟油，提高了热效率。克服实心发热元件比表面积小，传热效率低的不足。无需预热，第一口烟雾就非常饱满，给予消费者更好的入口体验。
本公开所述电热雾化元件2有效发热形状为长方形或C字形的多孔金属纤维毡片，但不限于此。C字形有效发热形状，增大向微孔陶瓷的传热面，更有利于预热膏状烟油。多孔金属纤维粘片两端焊接电极引线，两电极与多孔金属纤维粘片联接的部分被对称的固定嵌埋在微孔陶瓷管1两侧管体内，在陶瓷体外部留有适量长度与电路相连。
电热雾化元件2两个电极引线3之间的电阻范围为0.2-10欧姆。多孔金属纤维毡片作为电热雾化元件可以发热也可导油，提升加热效率。同时对多孔金属纤维毡片的形状进行设计，可以在雾化的同时部分热量传递到微孔陶瓷管1体对膏状体烟油进行预热，不需要设计另外的预热电路和预热时间，实现和雾化液体烟油同样的效果。
综上，本公开的可回收冷凝液的电子烟雾化芯及电子烟，相对于现有技术至少具有以下优势之一：
(1)本公开公开了一种陶瓷雾化芯，该雾化芯由微孔陶瓷管和焊 接电极引线多孔金属纤维毡片热压灌注烧结而成；微孔陶瓷管用来固定电热雾化元件，兼具储油、补充导油、分散部分热量雾化烟油、回收气流通道内的烟油冷凝液、防止漏油的功能；
(2)多孔金属纤维作为电热雾化元件，即可雾化又可导油，提高雾化效率；
(3)本公开不但可以雾化烟油，也可以雾化膏状物体；
(4)本公开装配工艺简单，有利于工业化生产。
需要说明的是，尽管已经参照本公开的特定示例性实施例示出并描述了本公开，但是本领域技术人员应该理解，本公开并不局限于上述实施方式，凡是对本公开的各种改动或变型不脱离本公开的精神和范围，倘若这些改动和变型属于本公开的权利要求和等同技术范围之内，则本公开也意味着包含这些改动和变型。
特别地，在不脱离本公开精神和教导的情况下，本公开的各个实施例和/或权利要求中记载的特征可以进行多种组合和/或结合，即使这样的组合或结合没有明确记载于本公开中。所有这些组合和/或结合均在本公开的保护范围。因此，本公开的范围不仅由所附权利要求来进行确定，还应由所附权利要求的等同物来进行限定。
