 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、2所示，本发明第一实施例的电子烟雾化组件10，包括多孔基体11、以及设置在多孔基体11上的发热层12。
多孔基体11用于导液（烟液），可以是多孔陶瓷材料、碳材料或泡沫金属；多孔陶瓷材料包括莫来石、氧化铝、二氧化硅、碳化硅、硅藻土中至少一种。多孔基体11可以是正方体、长方体等多面体，也可以是圆柱体等结构。
发热层12为区别于发热丝的层状结构，用于加热雾化烟液。发热层12的两端分别设有连接部13，用于与电子烟供电装置电连接。
发热层12可以设置在多孔基体11的表面或者内部。对应多孔基体11的形状，发热层12可以设置在多孔基体11的至少一表面上。
发热层12可以为电子浆料、碳粉或金属粉末通过印刷、涂覆、喷涂、浸泡、真空镀和夹包方式中至少一种设置在多孔基体11的表面或内部。其中，电子浆料包括含碳浆料、含不锈钢浆料、含银浆料、含金浆料、含镍浆料、含钛浆料、含铝浆料、含铜浆料中的至少一种；金属粉末包括不锈钢、镍、钛、镍铬合金中至少一种。
根据发热层12所需的阻值，设置发热层12的尺寸、形状及选择对应的材料制备。
作为选择，采用电子浆料制备发热层12时，将电子浆料通过采用印刷、涂覆、喷涂或浸泡方式设置在多孔基体11上，再通过300℃-1000℃下高温烘烤，使得电子浆料固化形成发热层12。采用碳粉或金属粉末制备发热层12时，将碳粉或金属粉末通过真空镀或喷涂方式设置在多孔基体11上，形成发热层12。
连接部13与发热层12一体形成。即，采用电子浆料、碳粉或金属粉末制备发热层12时，也在发热层12两端形成连接部13。对于碳粉形成的发热层12及连接部13，可进一步在连接部13上设置金属层或在其中加入金属粉末，提高连接部13的导电性。
在本实施例中，如图1、2所示，发热层12设置在多孔基体11的一个表面上，发热层12包括一条发热带121；发热带121呈直线型两个连接部13分别连接在发热带121的两端。连接部13的面积大于发热带121的面积。

本发明的电子烟雾化组件的制作方法，可包括以下步骤：
S1、在整块的基体上设置发热材料层；
S2、将发热材料层处理为多个间隔排布的发热层，每一个发热层的两端分别形成有连接部；
S3、对应发热层及其两端的连接部将整块的基体切割成多个独立的多孔基体，每一个多孔基体与其上的发热层和连接部形成一个雾化组件。
下面以制作第一实施例的雾化组件10为例对本发明的制作方法进行详细说明。
参考图1及图8所示，雾化组件10的一种实施例制作方法可包括以下步骤：
S1、在整块的基体100上设置发热材料层110，如图8中（a）的侧视图所示。
基体100可以是整块的多孔陶瓷或碳材料制成的碳块等。
在一种选择性实施方式中，采用真空镀或喷涂方式将碳粉或金属粉末设置在整块的基体100的表面上，碳粉或金属粉末在基体100的表面上形成发热材料层110。
在另一种选择性实施方式中，采用印刷、涂覆、喷涂或浸泡方式将电子浆料设置在整块的基体100的表面上，在300℃-1000℃下高温烘烤，使得电子浆料固化形成发热材料层110。
S2、将发热材料层110处理为多个间隔排布的发热层12，每一个发热层12的两端分别形成有连接部13，如图8中（c）的俯视图所示。
处理方式为激光切割或化学腐蚀等。具体地，处理时，如图8中（b）的侧视图所示，在发热材料层110上放置有机膜120，有机膜120上对应每一个发热层12所需形状的周围位置镂空，通过激光切割或化学腐蚀等方式将镂空处的发热材料层部分去除。完成后，排去有机膜120及发热材料层110的边框废料。
S3、对应发热层12及其两端的连接部13将整块的基体100切割成多个独立的多孔基体11，每一个多孔基体11与其上的发热层12和连接部13形成一个雾化组件10，如图8中（c）至（d）所示。
切割时，可沿着图8（c）中的切割线（虚线）进行。切割可以采用激光切割、线切割及砂轮切割等方式实现。
切割后，还包括对雾化组件10进行清洗、烘干等处理。
可以理解地，上述的制作方法还适用于第二实施例至第六实施例的雾化组件的制作。
在其他实施例的雾化组件的制作方法中，在切割前还包括在每一个发热层上设置导体，用于与电子烟的供电装置电连接。
其他实施例的雾化组件的制作方法，例如发热层以夹包方式设置，其制作方法可包括以下步骤：
S1、在一个或两个基体生坯的表面上设置发热材料层。
作为优选，基体生坯为多孔陶瓷生坯。
S2、将发热材料层处理为多个间隔排布的发热层，每一个发热层的两端分别形成有连接部。处理方式可参考上述的实施例制作方法。
将两个基体生坯相对覆合形成一个整体，将发热材料层夹设在其中；在300℃-1000℃下烧结，使基体生坯形成多孔的基体，提高结构强度。烧结时，基体生坯的制孔剂等挥发去除。覆合在一起的基体生坯经烧结后形成整块的基体。
S3、对应发热层及其两端的连接部将整块的基体切割成多个独立的多孔基体，每一个多孔基体与其上的发热层和连接部形成一个雾化组件。
雾化组件中，发热层位于多孔基体的内部，发热层两端的连接部分别露出多孔基体的相对两端，便于与电子烟的供电装置电连接。
综上，本发明的雾化组件的制作方法，可以一次制得多个雾化组件，实现雾化组件的模块化、批量化及自动化生产，一致性好且提高了生产效率。
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。
