实施例1
一种超声雾化片，如图5所示，包括陶瓷基材104，其上表面设有上银层103，其下表面设有下银层105；所述陶瓷基材104、上银层103和下银层105形成压电陶瓷106，在压电陶瓷106的上表面设有用于保护上银层103的玻璃釉102；所述玻璃釉102上表面设有烟油吸附层而形成压电陶瓷组件10，所 述烟油吸附层为陶瓷浆层107，该烟油吸附层用于吸附及导输烟油。
如图5所示，其中压电陶瓷组件烧结制作工艺流程包括如下步骤：
1、喷涂上下银层在陶瓷基材的上下表面即为压电陶瓷。
2、在压电陶瓷的上银层表面又喷涂一层玻璃釉层，主要用于保护上银层，因为玻璃釉层与液体直接接触。玻璃釉层有耐酸碱性等特性。
3、在压电陶瓷的玻璃釉层表面又喷涂各种形状的陶瓷浆层，陶瓷浆层主要用于吸附烟油或导输烟油作用，因为陶瓷本身具有多孔性及导油特性。
4、得出压电陶瓷组件的初胚体。
5、将压电陶瓷组件初胚体放置火炉内，通过高温600℃-900℃烧结10-14小时。
6、通过冷却装置将烧结后的压电陶瓷组件冷却12-15小时即可得出成品。
综上所述，本实施例的超声雾化片的烧结制作方法为：将陶瓷浆喷涂或印制在压电陶瓷雾化片的玻璃釉层上，然后通过烧结工艺将其做成一体，有利于提高超声雾化片的导油性能、雾化效果及其寿命；同时简化电子烟产品结构，组装简便。
实施例2
一种超声雾化片，如图6所示，与实施例1结构类似，其区别在于，所述玻璃釉102上表面形成凹凸表面108，该凹凸表面108上固定有作为烟油吸附层的多孔材料层101，优选为棉或无纺布，且凹凸表面108与多孔材料层101之间通过高温胶水粘接相连。所述多孔材料层101的厚度为0.1mm-0.5mm。
其中，通过粘结工艺制作压电陶瓷的流程包括如下步骤：
1、在陶瓷基材的上下表面喷涂上下银层，即为压电陶瓷。
2、在压电陶瓷的上银层表面又喷涂一层玻璃釉层，主要用于保护上银层，因为玻璃釉层与液体直接接触，玻璃釉层有耐酸碱性等特性。
3、在压电陶瓷的玻璃釉层表面打磨，然后将高温胶水涂抹在其表面，最后将多孔材料粘附在玻璃釉层的表面，即可形成一个可导油的压电陶瓷。其中在玻璃铀层上打磨，使其表面有凹凸不平的表面，然后涂上一层高温胶水。多孔材料为棉、无纺布等。优选多孔材料的厚度为0.1-0.5mm。
4、通过烘干机将其烘干即可得到有导油功能的压电陶瓷成品。
综上所述，本实施例利用粘结方法的制作超声雾化片的方法为：在压电陶瓷雾化片的玻璃釉层上进行打磨，然后将高温胶水喷涂在打磨区域处，再将导油棉等多孔材料粘结在上面，使其做成一体，有利于提高超声雾化片的导油性能、雾化效果及其寿命；同时简化电子烟产品结构，组装简便。所用的高温胶水有强力万能胶、尼龙粘、AB粘等。
实施例3
一种超声雾化器，如图1，2和4所示，包括具有吸嘴1的外套管2，固定在外套管2下端的导油组件3，以及固定在导油组件3下端的雾化芯4；其结构特点是，所述雾化芯4内装有所述的超声雾化片，该超声雾化片的烟油吸附层与所述导油组件3接触。
如图3所示，所述外套管2内设有油仓，所述导油组件3内设有用于导通所述油仓与所述烟油吸附层的导油结构，使油仓内的烟油通过导油结构输送至烟油吸附层，然后经过超声雾化成烟油雾后流向吸嘴1。所述外套管2与导油组件3之间、导油组件3与雾化芯4之间可拆卸地固定相连，由此，外套、导油 组件和雾化芯之间的连接均为可拆卸连接，降低使用成本、方便更换损坏部件以及方便清洁，提升用户体验。
优选地，所述导油组件3包括连接件5，其用于与外套管2相连的，且在连接件5与外套管2之间设有密封圈6；固定座8，装在固定座8内的硅胶座7，以及位于硅胶座7内的导油棉9；所述固定座8的侧壁上开有通气孔或通气槽。
优选地，所述雾化芯4包括底座12，装在底座12内的硅胶套11；内电极14，其通过绝缘环13装在底座12下端且位于内电极14和底座12之间；以及作为超声雾化片的压电陶瓷组件10，该压电陶瓷组件10设置在硅胶套11内，且压电陶瓷组件10的下表面与所述内电极14的顶端电接触。
本发明的烟油吸附层与超声雾化片做成一体，且烟油吸附层的表面总面积小于在超声雾化片该表面的面积，也就是说烟油吸附层设置在超声雾化片的局部表面，使其雾化启动速度快，每口烟油雾量一致，雾化效果更好，寿命更长。
本发明的超声雾化片也可以通过封装工艺和腐蚀工艺，使烟油吸附层与超声雾化片做成一体，即可以将烟油吸附层固定在超声雾化片表面，使其更加牢固，不易脱层即可。
所述超声雾化器设置有可自动导油的超声雾化片，通过该超声雾化片上的多孔材料层与导油结构抵接即可实现导油超声雾化的作用，使雾化器结构简单、组装简便及不会出现泡油的现象。
烟油吸附层与超声雾化片通过封装工艺的装配方法将其做成一体，提高超声雾化片的导油性能及雾化效果。
上述实施例阐明的内容应当理解为这些实施例仅用于更清楚地说明本发 明，而不用于限制本发明的范围，在阅读了本发明之后，本领域技术人员对本发明的各种等价形式的修改均落入本申请所附权利要求所限定的范围。
