进一步地，在一些实施例中，该基座20呈柱状，其与该固定管10可拆卸连接。该基座20包括顶壁和侧壁；该基座20的顶壁开设有插接孔，该插接孔用于与该发热体30插接。
进一步地，在一些实施例中，该发热体30呈纵长的片状，可以理解地，在其他一些实施例中，其不限于呈纵长的片状，其也可以呈柱状或者针状，其远离基座20的一端设有尖顶结构，该尖顶结构呈三角形、楔形或者锥形，其包括基体31以及设置于该基体31上的测温电阻电路32。该基体31呈片状，其为采用导磁导电材料制成，该导磁导电材料可以为铁、铁合金、镍、镍合金、石墨或者铁氧化物中的一种或者多种，其具有导电性，并且具有磁感效应，其能够在感应线圈50在通电状态下释放电磁能量后产生涡流效应从而产生热量对气雾形成基质100中的成分进行加热。该测温电阻电路32铺设于该基体31的表面，其可用于该基体31一体成型，具体地，该基体31的表面可印刷绝缘层，该测温电阻电路32可设置于该绝缘层上，其两端可通电流，其可根据电阻变化实时得到基体31的温度。可以理解地，在其他一些实施例中，该测温电阻电路32可以省去。
如图3至图6所示，在一些实施例中，该线圈固定筒40呈柱状，其内径可略大于该固定管10的外径，其内侧可设置进气通道。该进气通道连通该第一进气口和第二进气口112，以便于气体进入固定管10中。该线圈固定筒40的外侧壁设有多个定位槽，该多个定位槽沿该线圈固定筒40的轴向间隔设置且沿该线圈固定筒40的周向延伸设置，其用于供该感应线圈50绕设，并且可避免该感应线圈50从该线圈固定筒40脱出，解决由高频利兹线（多股极细小漆包线组成）形成的感应线圈50柔软不易定位的问题，在一些实施例中，其还能够限定感应线圈50的匝间距，进而准确控制感应线圈50的匝间距，且使得该感应线圈50贴合筒壁的面积最大化，进而起到减少漏磁和提高能量转化效率的作用。
再如图4所示，进一步地，在一些实施例中，该感应线圈50采用高频利兹线（多股极细小漆包线组成）制成，其呈螺旋状，其绕设于该线圈固定筒40的定位槽41上。在一些实施例中，该感应线圈50的总高度h与该发热体30插入该固定管10中的气雾形成基质100深度h1之比为1:1~3:1,即h/h1=1:1~3:1。在该感应线圈50输入功率不变的状态下，该关系式觉得了发热体30上高温区的分布，比值小，则该发热体30上的高温区小，此时，高温区温度越高越集中；比值大，高温区则越大，且温度越分散。使用者可根据该关系式，对应调整该该发热体上高温区的分布，进而可避免因该发热体温度过高而导致烫手无法使用，提高用户体验感。在一些实施例中，可以选择的，该感应线圈50的总高度h与该发热体30插入该固定管10中的气雾形成基质100深度h1之比为1.2:1~1.5:1，即h/h1=1.2:1~1.5:1。在一些实施例中，该发热体30插入固定管10中的气雾形成基质100的深度h1的取值可以为9~15mm。
进一步地，在一些实施例中，该感应线圈50的内径d与该发热体30的宽度d1之比可以为1.2:1~3:1，即d/d1=1.2:1~3:1，该关系式决定了升温效率的变化。该感应线圈50的内径d与该发热体30的宽度d1的比值越小，升温效率越高。在一些实施例中，该d1取值范围3~5.5mm。
再如图5所示，进一步地，在一些实施例中，该感应线圈50可包括第一感应区A、第二感应区B以及第三感应区C。该第一感应区A、第二感应区B以及第三感应区C朝靠近该固定管10的第一端依次设置。该第一感应区A的平均匝间距大于第三感应区C的平均匝间距，第三感应区C的平均匝间距大于该第二感应区B平均匝间距，从而使得穿过该发热体30各区域的磁力线数量相同，温度场分布更为均匀。相应地，该线圈固定筒40上与该第一感应区A对应设置区域中单位高度的定位槽41的数量大于该线圈固定筒40上与该第三感应区C对应设置区域中单位高度的定位槽41的数量；该线圈固定筒40上与该第三感应区C对应设置区域中单位高度的定位槽41的数量大于该线圈固定筒40上与该第二感应区B对应设置区域中单位高度的定位槽41的数量。
再次参阅图4，在一些实施例中，该电磁加热组件还包括防护膜60。该防护膜60设置于该感应线圈50外周，具体地，其包裹于该感应线圈50的外周，其用于增大电感量，提高升温速率；防止磁泄露影响电子元器件工作和对人体造成伤害。该防护膜60可呈柱状，其高度大于感应线圈50的总高度，具体地，其高度可与线圈固定筒40的高度相适配。在一些实施例中，该防护膜60的高度H为h+2h3，其中该h3的取值范围为0.5~6mm。在一些实施例中，该防护膜60为铁氧体膜，其材质为锰锌铁氧体，当然，可以理解地，在其他一些实施例中，该防护膜60不限于锰锌铁氧体材质，其可由由三氧化二铁和一种或几种其他金属氧化物（例如：氧化镍、氧化锌、氧化锰、氧化镁、氧化钡、氧化锶等）配制烧结而成。在一些实施例中，该防护膜60的磁导率为500~2000，其厚度为0.1~0.5mm。
可以理解的，以上实施例仅表达了本实用新型的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，可以对上述技术特点进行自由组合，还可以做出若干变形和改进，这些都属于本实用新型的保护范围；因此，凡跟本实用新型权利要求范围所做的等同变换与修饰，均应属于本实用新型权利要求的涵盖范围。
