发热管1为一个中空的筒状结构，发热管1具有轴向连通的第一容置腔和第二容置腔，第一容置腔的内径和轴向长度与气溶胶形成基质6的长度适配，第一容置腔用于容纳气溶胶形成基质；第二容置腔的内径和轴向长度与换热器2适配，第二容置腔用于容纳换热器2。第一容置腔的内径等于或略大于气溶胶形成基质6的外径，使得气溶胶形成基质6能够刚好插装在第一容置腔内，气溶胶形成基质6不会从第一容置腔脱离。发热管1具有第一端和第二端，第一容置腔从发热管1的第一端延伸至中部，第二容置腔从发热管1的第二端延伸至中部，第一容置腔和第二容置腔连通的位置更靠近第二端。其中，第一容置腔和第二容置腔之间可以为孔径相同和无分隔部的结构，第一容置腔和第二容置腔也可以为孔径不同或设有分隔部的结构。
本实施例中，换热器2具有良好的导热性，换热器2为金属或陶瓷等导热材质，换热器2用于传递热能，对穿过换热器2的空气进行加热，即对从发热管1的第二端进入气溶胶形成基质6的空气进行加热。
换热器2安装在发热管1的第二容置腔内，换热器2靠近换热器的第二端，换热器2可以焊接、卡接等方式与发热管1固定连接。换热器2为一个圆柱体结构，换热器2具有轴向的多个进气孔21，进气孔21与第一容置腔连通，用于将空气导入到气溶胶形成基质6内。优选的，换热器2设置有蜂窝式的进气孔21，蜂窝式结构能够提高进风与换热器2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，换热器2的进气孔21设置成为有煤球孔状或者几个较大的孔，虽然其效果低于蜂窝式的进气孔21，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。
本实施例中，发热管1内可以设置隔热件3，隔热件3位于可以位于第一容置腔和第二容置腔的连通处，隔热件3也可以位于第一容置腔或第二容置腔内。隔热件3可以固定换热器2上，隔热件3也可以固定在发热管1的内壁。
隔热件3与换热器2接触连接，隔热件3用于将气溶胶形成基质6和换热器2间隔开，避免换热器2直接对气溶胶形成基质6的端面进行加热，进而避免过高的温度烤焦气溶胶形成基质6。
隔热件3优选为环形结构的隔热圈，隔热件3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3也可以为其他结构，如隔热件3为工字型结构，隔热件3的两个端为环形板，两个环形板之间通过连接部连接，两个环形板分别与换热器2和气溶胶形成基质6连接，也能够换热器2和将气溶胶形成基质6间隔开。
本实施例中，加热体设置在发热管1的外侧，加热体包括第一加热体4和第二加热体5，第一加热体4和第二加热体5均为电阻发热片，第一加热体4和第二加热体5贴在发热管1的周向外侧面上，第一加热体4和第二加热体5能够将电能转为热能，其中第一加热体4和第二加热体5可以采用现有已知的加热材料。在其他实施例中，第一加热体4和第二加热体5也可以设置在发热管1的周向内侧面上，或者通过一体成型的方式将第一加热体4和第二加热体5设置在发热管1的内部（外侧面和内侧面之间），第一加热体4和第二加热体5的主体隐藏，仅露出两端。
本实施例中，第一加热体4靠近发热管1的第一端，第一加热体4位于第一容置腔的外侧，第一加热体4与第一容置腔内远离换热器2的一端相对应，第一加热体4用于加热远离换热器2的部分气溶胶形成基质6。第二加热体5靠近发热管1的第二端，第二加热体5位于第二容置腔的外侧，第二加热体5用于对换热器2加热，进而换热器2对进入气溶胶形成基质6的空气进行加热。第一加热体4和第二加热体5分别对气溶胶形成基质6的本体以及进入的空气加热，并且分别对气溶胶形成基质6的两端进行加热，能够更均匀的加热气溶胶形成基质6，提高吸食口感。
第一加热体4的片状长度大于第二加热体5的片状长度，第一加热体4覆盖发热管1的面积大于第二加热体5覆盖发热管1的面积，以增大覆盖气溶胶形成基质6圆周面，提高直接加热气溶胶形成基质6的效率。
本实施例中，第一加热体4和第二加热体5为相互独立的结构，第一加热体4和第二加热体5能够分别单独控制发热，该相互独立结构，指第一加热体4和第二加热体5可以具有单独控制的电路，当然第一加热体4和第二加热体5连接的电路也可以并列在一起。第一加热体4和第二加热体5分别单独控制发热可以实现不同的加热模式，如进行同步加热和异步加热，其中同步加热和异步加热的加热模式中第一加热体4和第二加热体5可以以不同的功率进行加热。
请参考图3和图5，条状结构的第一加热体4的两端分别为第一电连接端和第二电连接端，第二加热体5的两端分别为第三电连接端和第四电连接端。其中，第一电连接端和第三电连接端为相同的电极，第二电连接端和第四电连接端为相同的电极，如第一电连接端为正极，第二电连接端为负极，第三电连接端为正极，第四电连接端为负极。
本实施例中，第一电连接端和第三电连接端间隔分开设置，第一电连接端为第一焊盘A，第三电连接端为第二焊盘B，第二电连接端和第四电连接端通连接在一起，第二电连接端和第四电连接端连接合并形成第三焊盘C。其中，第一焊盘A、第二焊盘B和第三焊盘C分别用于焊接电线，以使得第一加热体4和第二加热体5连接到电路上，给第一加热体4和第二加热体5提供电能。将第二电连接端和第四电连接端连接合并为同一个电极，能够减少布线，降低成本，节约空间，同时不影响第一加热体4和第二加热体5分别单独控制发热。
在其他实施例中，第二电连接端和第四电连接端也可以间隔分开设置，第一电连接端和第三电连接端合并连接，也能够实现对第一电连接端和第四电连接端的单独控制供电。
本实施例的加热结构，由于设有相互独立的第一加热体4和第二加热体5，两个加热体可以分别单独控制加热，以使得第一加热体4和第二加热体5可以实现同步或异步加热，具有更多的加热模式，能够满足不同烟支或不同人群的吸食需求。
在其他实施例中，发热管1也可以包括第一发热管和第二发热管，第一发热管和第二发热管可以轴向对接成为一条加热管，第一发热管和第二发热管也可以间隔设置，两者通过其他连接件连接。第一容置腔位于第一发热管内，第二容置腔位于第二发热管内，第一发热管用于插装气溶胶形成基质6，第二发热管用于安装换热器2。第一加热体4设置在第一发热管的外侧，第二加热体5设置在第二发热管的外侧。发热管1拆分为两个管，也能够实现第一加热体4和第二加热体5分别单独控制加热。

第一加热体4和第二加热体5位于外管7的圆周外侧，第一加热体4和第二加热体5分别缠绕在外管7上。并且，第一加热体4与发热管1靠近的第一端的周向区域径向对齐，以使得第一加热体4能够对第一容置腔内远离换热器2的部分气溶胶形成基质6进行加热；第二加热体5与发热管1靠近第二端的周向区域径向对齐，以使得第二加热体5能够对第二容置腔内的换热器2加热。

在其他实施例中，外管7上也可以仅设置一个限位部，或者不设置限位部，电磁感应线圈通过缠绕束缚力固定在外管7上，也能够实现一定的轴向限位。
本实施例中，外管7和发热管1之间可以设有径向的间隙，该间隙可以用于容纳空气，在加热的过程中能够对间隙的空气一同进行加热，间隙空气能够起到热传递的左右，使得发热管1上的其他区域也能够受热，有利于提高加热效果。
本实施例中，第一加热体4和第二加热体5采用电磁感应的方式进行加热，并且两个第一加热体4和第二加热体5间隔分布，第一加热体4和第二加热体5形成两个独立的加热结构，同样能够分别单独控制加热，以使得第一加热体和第二加热体可以实现同步或异步加热，具有更多的加热模式，能够满足不同烟支或不同人群的吸食需求。
