在一个优选的实施例中，电阻加热器30大体呈销钉或者针状的形状，进而对于插入至气溶胶生成制品A内是有利的；同时，电阻加热器30可以具有大约12～19毫米的长度，大约2～4毫米的外径尺寸。
进一步在可选的实施中，气溶胶生成制品A优选采用加热时从基质中释放的挥发化合物的含烟草的材料；或者也可以是能够加热之后适合于电加热发烟的非烟草材料。气溶胶生成制品A优选采用固体基质，可以包括香草叶、烟叶、均质烟草、膨胀烟草中的一种或多种的粉末、颗 粒、碎片细条、条带或薄片中的一种或多种；或者，固体基质可以包含附加的烟草或非烟草的挥发性香味化合物，以在基质受热时被释放。
在实施中，电阻加热器30通常可以包括电阻加热元件、以及辅助电阻加热元件固定制备等的辅助基材。例如在一些实施例中，电阻加热元件是螺旋线圈的形状或形式。或者在又一些实施例中，电阻加热元件是结合于衬底上的导电轨迹的形式。或者在又一些实施例中，电阻加热元件是薄片的基材的形状。
进一步图2示出了一个实施例中电阻加热器30的各部分未装配前的分解示意图，包括：
加热器外壳31，被构造成是中空311的销钉或针状的形状，并且前端呈锥形尖端，便于插入至气溶胶生成制品A内，后端具有开口，便于在其内部装配各功能部件；
电阻加热元件32，用于发热；具体在结构上包括有被构造成沿加热器外壳31的轴向的一部分延伸的螺旋形状的电阻加热线圈320，以及分别连接在电阻加热线圈320的下端的第一导电引脚321、以及连接在电阻加热线圈320上端的第二导电引脚322。在使用中，第一导电引脚321和第二导电引脚322用于对电阻加热线圈320进行供电。
在图2所示的实施例中，电阻加热线圈320是被完全装配和保持在加热器外壳31的中空311内的，并且在完成装配后，电阻加热线圈320与加热器外壳31之间彼此导热。
进一步在图2所示优选的实施例中，电阻加热器30还包括基座或法兰33；在图中该基座或法兰33是陶瓷、PEEK等耐热材料；形状优选是环形。在装配中，将加热器外壳31下端通过高温粘胶或模制例如模内注塑等方式固定在基座或法兰33上；进而气雾生成装置可以通过支撑、夹持或保持等方式对基座或法兰33进行固定，进而对电阻加热器30实现稳定安装和保持。当然，在基座或法兰33与加热器外壳31下端装配后，第一导电引脚321和第二导电引脚322由基座或法兰33的中孔贯穿出来，进而便于与电路20连接。

图3示出了图2中电阻加热线圈320一个视角的剖面示意图，电阻加热线圈320的导线材料的截面形状是不同于常规圆形的宽或者扁的形状。在图3所示的优选实施中，电阻加热线圈320的导线材料的截面具有沿纵向延伸的尺寸大于沿垂直于纵向延伸部的径向延伸的尺寸，从而使电阻加热线圈320呈扁的矩形形状。
简单地说，以上构造的电阻加热线圈320与由圆形截面导线形成的常规螺旋状加热线圈相比，导线材料的形式完全地或至少是展平的。因此，导线材料沿着径向方向延伸呈较小的程度。通过这种措施，可以减少电阻加热线圈320中的能量损失。特别地，可以促进热量的传递。

进一步在实施例中，第一导电引脚321的第二区段3214具有大于第一区段3213的长度；以及第二导电引脚322的区段3224具有大于区段3223的长度。例如在一些具体的实施中，第一导电引脚321的第二区段3214具有大约20～40mm的延伸长度，以及第一导电引脚321的第一区段3213具有大约5～10mm的延伸长度。
进一步在实施中，第一导电引脚321的第二区段3214具有小于第一区段3213的电阻或电阻率；以及第二导电引脚322的区段3224具有小于区段3223的电阻或电阻率。
