Description

电子烟及其雾化装置和多层结构定向导液雾化芯 技术领域
本发明涉及香烟替代品，更具体地说，涉及一种电子烟及其雾化装置和多层结构定向导液雾化芯。
 背景技术
电子雾化装置因为其具有操作简单、使用方便等特点和优势，因此自发明以来，就在国内外产生巨大反响，拥有大量的使用者。
最新陶瓷雾化芯雾化技术是使用多孔陶瓷储存、传导雾化介质并通过陶瓷中的金属发热丝或陶瓷表面的发热膜将雾化介质雾化。
陶瓷雾化芯主要包括两个组成部分：
一是陶瓷基体，通常是一种多孔陶瓷，材质多为常见无机非金属氧化物，基体的主要作用有：（1）作为发热膜或者发热丝的结构支持；（2）基体中的孔隙可以存储雾化介质；（3）基体中的连通孔隙导液，在雾化过程中持续为发热丝或发热膜提供雾化介质。
二是发热材料，主要有金属发热丝和金属发热膜两种。陶瓷雾化芯烟雾量大、口感好，在抽吸体验上与以往的雾化技术相比有很大提升。
但是陶瓷雾化芯仍然存在以下亟待解决的问题：
（1）多孔陶瓷基体孔径大小及分布调整困难且可调空间较小，导致陶瓷基体导液速度与储液可调空间狭窄，孔径太小则储液不充分、导液不顺畅导致烟气温度过高甚至出现焦味，孔径太大则容易出现抽吸漏液影响口感；
（2）多孔的陶瓷基体仍然存在陶瓷颗粒掉落形成粉尘被用户吸入的安全隐患。
为了改善上述问题，需要能够对陶瓷基体内的孔道结构进行精确控制与调节，满足特定雾化介质对陶瓷基体的定制化需求，同时陶瓷基材安全性必须纳入考量。

 本发明的实施方式
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所示，本发明一个优选实施例中的电子烟包括雾化装置，雾化装置内设有雾化芯1，可以吸附烟油后将烟油加热雾化成烟气供用户吸食。
雾化芯1包括多块层叠设置的基片11、以及设置在两相邻的基片11之间的介质层12。介质层12将两相邻的基片11隔离，并让两相邻的基片11之间形成让烟液通过的导液通道13。
通过介质层12，可以将雾化芯1分成多层结构，两层基片11之间形成导液通道13，再通过介质层12的设置位置，可以让导液通道13定向流动，满足吸液和雾化的需求。层叠的基片11的数量至少可为两块，两相邻的基片11之间的介质层12将基片11隔离，形成导液通道13。
基片11是多层定向导液雾化芯1的骨架，基片11叠加形成的具有方向性的间隙构成烟液等雾化介质的传导路径，并且间隙空间可储存大量雾化介质，让雾化芯1形成类似陶瓷等多孔雾化芯1的结构。
介质层12将相邻的两块基片11结合使多块基片11形成稳定的层状结构，可以通过调节介质层12的厚度、宽度等尺寸，来调节相邻基片11件定向导液通道13的结构尺寸，另外，可以调整介质层12的分布即可控制导液通道13的数量与宽度。
导液通道13可调节，使雾化介质适配性强，层间直通导液通道13储液量大，导液速度快，可保证足够烟雾量的条件下避免焦味的产生。
基片11采用无机材料或有机材料，基片11也可采用金属材质，且金属材质的基片11进行了绝缘处理，避免与电极形成短路。
基片11的外形为片状，也可以是任意曲面形状，能层叠即可。优选地，基片11的厚度均匀，可以为0.1-3mm不等，基片11厚度方向投影边缘尺寸控制在1-20mm，避免尺寸过大或过小。
基片11材料选择范围广，金属、玻璃等其它耐高温材料均可，无机、有机或金属的致密材料，可大幅降低基片11颗粒脱落产生粉尘，降低安全风险。层叠设置的基片11使得雾化芯1的外形尺寸一致性好，装配面很平整。
介质层12包括至少一种无机非金属氧化物，在本实施例中，介质层12厚度5μm-500μm，宽度0.5-10mm，介质层12数量可以根据需要适当增减。
可以通过改变介质层12的厚度、宽度和数量、基片11材质及形状，以更加精确控制雾化芯1的导液速度和储液能力，从而更好适配各种雾化介质或满足客户对口感的差异化追求。
优选地，本实施例中，每一介质层12包括在两相邻的基片11之间设置的两介质区121，且两介质区121分别设置在两相邻的基片11的两相对边，在两相邻的基片11之间形成横向贯通的导液通道13。
两相邻的基片11之间介质层12将基片11的侧面密封，可以防止侧面漏液，让烟油只从导液通道13流通。
雾化芯1还包括发热膜14和引线台15，发热膜14设置在层叠的基片11的侧面，且与导液通道13的端部位置对应，引线台15分别与发热膜14和电源电性连接，让发热膜14通电发热对流过导液通道13的烟液加热。在其他实施例中，发热膜14和引线台15也可通过组装与基片11贴合。
发热膜14设置在层叠的基片11的一侧面，对导液通道13的一端封盖，使发热膜14对导液通道13全覆盖。为了让烟气通过发热膜14，发热膜14上分布有供雾化的烟液通过的气孔。优选地，发热膜14为多孔金属材质的发热膜14。
与多个导液通道13对应的发热膜14并联发热将导液通道13传导过来的雾化介质充分雾化，同时使整个雾化面温度更加均匀。
在其他实施例中，根据导液通道13的设置，发热膜14形状可以调整，例如，发热膜14对导液通道13部分覆盖，或者，发热膜14不覆盖导液通道13。
根据应用环境，发热膜14单线宽度0.1-20mm，发热膜14上孔的平均孔径1-100μm，电阻0.1-2Ω。
引线台15还包括在层叠的基片11的侧面设置的两引线台15，两引线台15分别与两介质区121所在的基片11的侧面位置对应，并与发热膜14电性连接。
通常，引线台15的材质可以为银、铜、金、铂等导电材料中的一种或几种，引线台15的作用是将发热膜14并联，引线台15可以充当电极，使得雾化芯1无需额外引线台15即可实现安装。
优选地，两引线台15和发热膜14位于层叠的基片11的同一侧，并分别与发热膜14电性连接。引线台15和发热膜14位于同一侧，优选地，并覆盖在导液通道13之外的区域，对无发热膜14的区域形成封堵，避免漏液。
可以理解地，上述各技术特征可以任意组合使用而不受限制。
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。
