下安装筒5的下端和加热管1的下端设有对齐的第二进气孔11，第二进气孔11用于将空气引入到第一进气孔321中进行加热，实现气流导通。第二进气孔11也可直接设置在下连接帽51的端面上，也能够起到气流导通的作用。
本实施例中，在加热管1内的中部还设有固定件6，固定件6为环形结构，固定件6设置在加热体2和下安装筒5之间。固定件6具有多个作用，一是限位加热体2和下安装筒5，二是限位电磁感应线圈31和电磁感应发热芯32。
具体的，上安装筒4的外径比下安装筒5大，上安装筒4的内径与加热体2内的内径一样大，上安装筒4和加热体2串联用于插装气溶胶形成基质7。固定件6由一个大环结构和一个小环结构轴向并排而成，大环结构和小环结构之间形成一个朝上的沉台，固定件6的大环结构的内径等于或略小于加热体2的外径，加热体2的下端插接在固定件6上端的沉台上。固定件6的小环结构外径等于或略大于下安装筒5的内径，固定件6的小环结构卡入下安装筒5的中，固定件6连接在加热体2和下安装筒5之间，并实现对加热体2和下安装筒5之间的相互限位。
固定件6的小环结构卡入下安装筒5的内台阶中，还能够将电磁感应发热芯32固定在下安装筒5中，固定件6的小环结构内具有卡槽，电磁感应发热芯32的上端具有径向凸起的卡扣，卡扣与卡槽连接，以使得电磁感应发热芯32固定在固定件6上，并且电磁感应发热芯32悬空在下安装筒5内，以使得电磁感应发热芯32的热量均能够通过固定件6传递给，电磁感应发热芯32与固定件6还可以通过螺纹连接等方式实现连接固定气溶胶形成基质7或加热体2。固定件6的大环结构外径大于下安装筒5的外径，使得固定件6能够用于限位电磁感应线圈31。下安装筒5的下端还设有限位件52，限位件52为一个限位环，限位件52也可以为若干个径向凸起的限位块，限位件52和固定件6的大环结构将电磁感应线圈31限位固定在下安装筒5上，以使得电磁感应线圈31和电磁感应发热芯32在径向上对齐，提高加热效率。
本实施例中，固定件6为硅胶材质，还能够用于将电磁感应发热芯32的热能传递至气溶胶形成基质7的端部，起到均热烘烤的作用。
在其他实施例中，固定件6也可以通过螺纹连接等方式与上安装筒4和下安装筒5连接。
在其他实施例中，加热管1的长度与上安装筒4适配，下安装筒5对接在加热筒1的外侧，下安装筒5的外侧再套设防护层，也能够实现对气溶胶形成基质7的周向加热及进入的空气加热。
本实施例中，气溶胶产生装置的加热结构的加热方法及加热原理如下：
第一步：预热阶段，使用加热体2对气溶胶形成基质7周向加热，保证快速出烟；但本部分的接触式电阻加热（周向发热体加热）非必要的过程。
第二步：当气溶胶形成基质7被抽吸完一二口或者预热完成后过了一定时间后，气溶胶形成基质7底部的电磁加热器3启动，快速升温，快速加热。
第三步：非接触式空气能加热：电磁加热器3加热，使得电磁感应发热芯32外表层急速升温，加热芯升温后，使得电磁感应发热芯32沿周向分布的第一进气孔321里面的空气充分加热起来；
第四步：电磁感应具有趋肤效应，使得电磁感应发热芯32金属表层温度较高，金属表层升温后，热量又能辐射和传导到第一进气孔321里面的空气中，热空气通过热传导和对流等方式给气溶胶形成基质7加热。
本实施例的气溶胶产生装置的加热结构，由于加热结构包括加热管1和电磁加热器3，加热管1用于对气溶胶形成基质侧面（周向）加热，电磁加热器3用于对进入气溶胶形成基质的空气加热，使得加热结构能够对气溶胶形成基质的侧面加热，还能够对进入气溶胶形成基质的空气进行加热，实现对气溶胶形成基质烘烤均匀和透彻，具有更好的吸食效果。
实施例二：
本实施例提供了一种气溶胶产生装置，气溶胶产生装置为加热不燃烧装置，气溶胶产生装置包括壳体和上述实施例中的加热结构，加热结构安装在壳体内。壳体内还有电源和电线，电源通过电线与加热结构连接，电源给加热结构供电，加热结构将电能转为热能对气溶胶形成基质进行加热烘烤。
本实施例的气溶胶产生装置采用上述实施例的加热结构，能够对气溶胶形成基质的侧面和底部加热，及对进入气溶胶形成基质的空气进行加热，实现对气溶胶形成基质烘烤均匀和透彻，具有更好的吸食效果。
