请参考图1和图2，本实施例的气溶胶生成装置的发热管主要包括发热体1、第一电极2和第二电极3，发热体1位于中部，第一电极2和第二电极3连接在发热体1的两端。其中，发热体1、第一电极2和第二电极3均为管状结构，发热体1为陶瓷复合材料，第一电极2和第二电极3为金属材料。
请参考图3，发热体1包括外层11、中间层12和内层13，外层11和内层13均为绝缘陶瓷，中间层12为导电线路，发热体1的三层材料通过高温烧结而成。导电线路包括若干个线路条121，如具有4个或6个线路条121，线路条121的数量可以根据需要设置。线路条121沿着轴向延伸设置，线路条121从发热体1的一端延伸至另一端，线路条121之间在周向相互间隔开设置，多个线路条121形成多瓣式结构布局，线路条121的宽度及间距均可以根据需要设置成预定值，以满足加热需求。线路条121在通电后能够将电能转为热能，对烟支进行加热烘烤。若干个线路条121的阻值相等，或者若干个线路条121的阻值成预设比例关系，如4个线路条121的阻值之间的比值为1:1.5:2:3。
优先的，若干个线路条121沿着轴向均匀分布设置，即线路条121具有相同的形状、宽度及间距。均匀分布的线路条121有利于对烟支进行均匀加热，以满足大部分吸食需求。当然，若干个线路条121可也设置成为不同形状、不同宽度及不同间距，以适配特殊情况下烟支加热需求。
请参考图4和图5，本实施例中，线路条121为直线型结构，线路条121与发热体1的轴向平行。

本实施例中，导电线路还包括连接线条122，使得多个线路条121连接到一条线路中，简化了导电线路，能够对多个线路条121进行单独控制或同时控制，以实现线路条121的先后发热或同步发热，以满足不同吸食需求。
在其他实施例中，导电线路不设置连接线条122，第二电极3上也设置多个第二触点31，线路条121的两端分别与第一触点21和第二触点31一一对应连接，导电线路形成多条并联电路，虽然增加了导电线路的复杂性，但也能够实现多个线路条121进行单独控制或同时控制。
本实施例的发热管，由于导电线路分为若干个线路条121，若干个线路条121沿轴向延伸并相互间隔设置，形成瓣式结构布局，使得线路条能够根据需求进行同步同温或异步异温加热，起到更好的加热效果，以满足不同吸食需求。
实施例二：
