进一步的，所述导电通路通过电路印刷机印刷在发热载体上，然后在足够温度下的还原气氛中持续一定时间烧制而形成第一主体。
进一步的，第一主体的烧制温度为1400℃-1600℃，还原气氛为在H2气体环境中，烧制时间为18h-24h。
进一步的，所述导电通路完全或部分形成电阻加热层，距离第二主体不超过第一主体的厚度。
进一步的，所述电阻加热层与第二主体的距离小于等于0.3mm，以增加热量的利用效率，提高雾化效果。
进一步的，所述发热载体完全或局部由陶瓷形成。
进一步的，所述导电通路由金属钨锰料浆结合瓷粉组成。

根据本发明的第二方面，提供了一种复合的陶瓷雾化器的制备方法，其特征在于第一主体和第二主体采取施釉封接工艺一体成型，制备成整体，具体工艺步骤如下：
步骤一、步骤一、在第一主体表面施釉，釉面厚度控制在5-40μm之间，釉为透明釉，透明釉按质量百分比包括以下组份：透明熔块80％～94％、高岭土5％～19％、羧甲基纤维素(CMC)0.2％-1％，其中透明熔块的化学成分按照质量百分比为SiO2 40％-60％、Al2O32％-15％、Na2O 0-8％、K2O 0-5％、ZnO 3％-15％、BaO 2％-10％、CaO5％-15％、MgO 0％-10％，釉的熔化温度在600-1000℃，施釉前将釉浆的粘度调制到0.5—1.5Pa·s，对第一主体进行干燥、吹灰、擦水工序；

进一步的，步骤一中施釉方式是干法施釉或者刷釉。
上述工艺步骤中，釉的料浆粘度对刷釉工艺影响很大，釉的组成中透明熔块配方影响熔体粘度(η)，而熔体粘度(η)大小直接影响封接效果。熔体粘度小，容易发生多孔陶瓷通过毛细管力吸釉，而粘度过大使得釉无法铺展，进而造成多孔陶瓷与MCH陶瓷的结合度不高。熔体粘度大小应该控制在2＜lgη＜6之间。
本发明的有益效果在于：将多孔陶瓷材料和发热陶瓷材料通过施釉烧制工艺一体封接成型，强度高，使用寿命长，同时清洁安全的多孔陶瓷材料用于导液，均匀发热的陶瓷材料用于加热雾化，避免了烟油的碳化以及炸油现象的发生。

羧甲基纤维素(CMC)主要用于调节釉料浆的粘度，从而能够使其在刷釉工艺中能够很好的铺展，又不至于渗入第二主体中；而釉的配方中，透明熔块中二氧化硅SiO2含量越高，氧化钾K2O，氧化钠Na2O含量越低，在烧结的高温状态下，熔体粘度越大，会使釉不能很好的接触第一和第二主体，导致粘结强度不高，透明熔块中二氧化硅SiO2含量越低，氧化钾K2O，氧化钠Na2O含量越高，在烧结的高温状态下，熔体粘度越小，会使釉进一步渗入第二主体中，堵塞孔隙，并且粘结强度也不会很高，因此合适的釉配方包括料浆粘度和熔体粘度是本技术的关键。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何属于本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。
