请参考图3，本实施例中，加热管1的周向外侧面在展开状态下为矩形面，矩形面的长为加热管1的外侧面周长，矩形面的宽为加热管1的轴向长度。该矩形面沿着对角线划分为上三角区域和下三角区域，上三角区域的底边为加热管1的第一端边缘，下三角区域的底边为加热管1的第二端边缘，第一发热体2弯曲分布在上三角区域内，第二发热体3弯曲分布在下三角区域内。其中，第一发热体2和第二发热体3大致分别位于上三角区域和下三角区域内，由于第一发热体2和第二发热体3为弯曲的片条状结构，第一发热体2和第二发热体3的弯曲转折处也会延伸到对方所在的区域内。
本实施例中，第一发热体2分布在上三角区域内，使得第一发热体2覆盖加热管1的面积从第一端向第二端逐渐减小，第一发热体2主要对加热管1的第一端内的气溶胶形成基质6进行加热，同时第一发热体2还能够对加热管1的第二端内的气溶胶形成基质6进行预热或保温。第二发热体3分布在下三角区域内，使得第二发热体3覆盖加热管1的面积从第二端向第一端逐渐减少，第二发热体3主要对加热管1的第二端内的气溶胶形成基质6进行加热，同时第二发热体3还能够对加热管1的第一端内的气溶胶形成基质6进行保温或预热。
请参考图3和图5，第一发热体2的两端分别为第一电连接端21和第二电连接端22，第一电连接端21位于加热管1的第一端，第二电连接端22延伸至加热管1的第二端。第二发热体3的两端分别为第三电连接端31和第四电连接端32，第三电连接端31位于加热管1的第二端，第四电连接端32延伸至加热管1的第一端。其中，第一电连接端21和第四电连接端32为相异的电极，第二电连接端22和第三电连接端31为相异的电极，如第一电连接端21为正极，第二电连接端22为负极，第三电连接端31为正极，第四电连接端32为负极，相异的电极分布在同一端有利于串联成为一条电路。
本实施例中优选的，第一电连接端21和第四电连接端32连接合并为同一个电极，第二电连接端22和第三电连接端31间隔分开设置，第一发热体2和第二发热体3形成串联电路。其中，第一电连接端21和第四电连接端32连接合并的电极为第一焊盘A，第三电连接端31单独成为第二焊盘B，第二电连接端22单独成为第三焊盘C，第一焊盘A、第二焊盘B和第三焊盘C分别用于焊接电线，以使得第一发热体2和第二发热体3连接到电路上，给第一发热体2和第二发热体3提高电能。将第一电连接端21和第四电连接端32连接合并为同一个电极，能够减少布线，降低成本，节约空间。
在其他实施例中，第一电连接端21和第四电连接端32也可以间隔分开设置，第一电连接端21和第四电连接端32分别单独成为一个焊盘，也能够实现对第一电连接端21和第四电连接端32的供电。
请参考图2和图6，本实施例中，加热器4安装在加热管1的第二端内，加热器4可以焊接、卡接等方式与加热管1固定连接。加热器4为一个圆柱体结构，加热器4具有轴向的多个进气孔41，进气孔41与加热腔11连通，用于将空气导入到气溶胶形成基质6内。优选的，加热器4设置有蜂窝式的进气孔41，蜂窝式结构能够提高进风与加热器4的接触面积，进而能够提高进风的加热效率，同时蜂窝式设置，还能够提高进风量。
在其他实施例中，加热器4的进气孔41设置成为有煤球孔状或者几个较大的孔，其效果低于虽然蜂窝式的进气孔41，但也能够起到一定的加热效果，相比现有技术仍然具有进步性。
在其他实施例中，加热器4的部分或全部位于加热管1的外部，加热器4的端部或端面与所述加热管1的第二端端面连接，加热器4的进气孔41仍然与加热腔11连通，同样能够实现对进入气溶胶形成基质6的空气进行加热。
本实施例中，加热器4为加热铜芯，加热器4具有延伸出的两个电极，电极用于与电路连接，加热器4用于将电能转为热能，对通过加热器4的空气进行加热，即对从加热管1的第二端进入气溶胶形成基质6的空气进行加热。
本实施例中，隔热件5安装在加热管1内，并且隔热件5与加热器4连接，隔热件5用于将气溶胶形成基质6和加热器4间隔开，避免加热器4过高的温度烤焦气溶胶形成基质。隔热件5优选为环形结构的隔热圈，隔热件5的中部具有通孔，通孔用于将热空气导入到气溶胶形成基质6内。
在其他实施例中，隔热件5也可以为其他结构，如隔热件5为工字型结构，隔热件5的两个端为环形板，两个环形板之间通过连接部连接，两个环形板分别与加热器4和气溶胶形成基质6连接，也能够加热器4和将气溶胶形成基质6间隔开。
本实施例中的加热结构，能够对气溶胶形成基质6的周向侧面不同位置进行同时或异步加热，还能够对进入到气溶胶形成基质6内的空气进行加热，有利于提高加热的均匀性。
本实施例中还提供一种加热控制方法，本加热控制方法基于上述的加热结构，能够更好的对气溶胶形成基质6进行加热，提高吸食效果。
加热控制方法包括如下步骤：
第一步、预热阶段，接通第一焊盘A和第三焊盘C，即给第一发热体2通电，第一发热体2给气溶胶形成基质6的中部位置加热，保证快速出烟；
第二步、当气溶胶形成基质6被抽吸一两口或者预热完成后过一定时间，接通第一焊盘A和第二焊盘B，即给第二发热体3通电，第二发热体3给气溶胶形成基质6的端部加热，同时第二发热体3的部分延伸至发热管1的第一端，能够保持特定的温度；
第三步、给加热器4通电，对进入气溶胶形成基质6内的空气进行加热，进而气溶胶形成基质6同时受到轴向侧面的加热以及热空气的内部加热，形成均匀受热。
本实施例中，第一发热体2、第二发热体3和给加热器4连接同一个电路中，形成串联电路，可以根据需要分配加热部件的电阻，以控制加热温度的高度。
本实施例的加热结构，由于加热结构包括加热管1和加热器4，并且加热管1上设有分布在第一端和第二端的第一发热体2和第二发热体3，第一发热体2和第二发热体3能够分别对气溶胶形成基质的中部和端部进行加热，加热器用于对进入气溶胶形成基质6的空气加热，使得加热结构能够对气溶胶形成基质6的侧面分区域加热，同时对进入气溶胶形成基质6的空气进行加热，实现对气溶胶形成基质6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的第一发热体2、第二发热体3和加热器4连接，电源给第一发热体2、第二发热体3和加热器4供电，第一发热体2、第二发热体3和加热器4将电能转为热能对气溶胶形成基质6的周向侧面以及进入的空气进行加热烘烤。
