在一些可选的实施中，电阻加热元件31c是常规的截面为圆形的导线材料绕制的电阻加热线圈；或者在一些优选的实施中，电阻加热线圈是由截面为扁形或矩形的导线材料绕制的电阻加热线圈。例如图5所示的电阻加热线圈31e，导线材料沿轴向方向的延伸尺寸大于沿径向方向的延伸尺寸，进而使螺旋线圈构造的电阻加热线圈31e在轴向方向上是展平的；对于热量的传递是有利的。在一个具体的实施中，电阻加热线圈31e的导线材料沿轴向方向的延伸尺寸为0.25～2mm、以及沿径向方向的延伸尺寸为0.05～0.2mm。
在对电阻加热元件31c的供电结构设计上，加热器30包括：
电极环33c，靠近末端320c并围绕基体32c的至少部分；
基体32c是导体材质制备的，例如不锈钢、镍铁合金等；

第一导线341c，通过焊接、压接等方式在连接位置B3处与基体32c连接导通，进而间接与电阻加热元件31c的上端导通；
第二导线342c，通过焊接、压接等方式在连接位置B4处与电极环33c连接导通，进而间接与电阻加热元件31c的下端导通；
而后再将第一导线341c和第二导线342c在连接至电路20，即可对电阻加热元件31c进行供电。
以及，加热器30还包括：
壳体元件35c，围绕电阻加热元件31c和基体32c的区段322c；壳体元件35c是避开基体32c的区段321c和电极环33c的。在装配后，由壳体元件35c将电阻加热元件31c限制和保持在基体32c的区段322c上，防止电阻加热元件31c松脱或移动。同时，在装配后由壳体元件35c至少部分界定加热器30的外表面。
进一步图3示出了壳体元件35c一个截面的示意图，图4示出了壳体元件35c展开后的示意图；壳体元件35c是由连续的箔片或薄片在电阻加热元件31c外卷绕或形成的。在实施中，形成壳体元件35c的箔片或薄片是金属箔(如不锈钢箔、NiCr合金箔)和非金属箔(如陶瓷/玻璃流延薄片)。在更加优选的实施中，形成壳体元件35c的箔片或薄片是采用导热系数高的金属或合金的箔片或薄片；例如金、银、铜、铝或它们的合金的箔片或薄片。
根据图4中所示，卷绕形成壳体元件35c的箔片或薄片是连续的矩形或条带等的形状。
在一些实施中，卷绕形成壳体元件35c的片材是单层的金属或合金的箔。在又一些更加优选的实施中，卷绕形成壳体元件35c的片材是至少两层的复合层的片材；在一具体的实施中，卷绕形成壳体元件35c的片材包括：
金属或合金层；以及，
应力补偿层，以及结合于金属或合金层；该应力补偿层提供卷绕过程中的弯曲或扭曲的应力补偿，以防止脆性较大的金属或合金层在卷绕过程中破裂或破碎。
在一些实施中，应力补偿层是柔性的层；具体的应力补偿层是柔性的聚合物材料；例如聚酰亚胺、自由聚丙烯、聚乙烯等。
金属或合金层具有大约0.5～30μm的厚度。应力补偿层具有与金属或合金层相同的厚度，通过涂布或沉积等方式形成于金属或合金层的至少一侧表面上。
进一步根据图3所示等优选实施，由箔片或薄片卷绕的管状的壳体元件35c大约具有0.1～0.5mm的壁厚。以及，壳体元件35c在最内侧的端部351c和最外侧的端部352c之间具有大约2～10个卷绕。
在具体的计算中例如图3中，箔片或薄片的卷绕是以由内向外的；由最内侧的端部351c开始计算，当箔片或薄片每卷绕角度360度为1个卷绕。例如图3中，最外侧的端部352c与最内侧的端部351c是基本相同的径向位置，在图3的具体实施中壳体元件35c具有6个卷绕，并形成有介于最外侧的端部352c与最内侧的端部351c之间的6个卷绕层353c。
进一步壳体元件35c在最内侧的端部351c是由电阻加热元件31c抵靠或贴合紧固的；以及为了防止最外侧的端部352c的散开，在卷绕之后将最外侧的端部352c处通过无机胶、釉料或焊料连接形成是壳体元件31形成闭合或密封的外表面，以防止气溶胶或冷凝液或气溶胶生成制品A的残渣进入至卷绕层之间。或者在又一些实施中，当壳体元件35c为非金属箔(如陶瓷/玻璃流延片)卷绕制备时，在卷绕之后通过层间焊接或烧结固化，对最外侧的端部352c处形成闭合或密封。
以上加热器30的制备中，可以在电阻加热元件31c外卷绕形成壳体元件35c后，进一步通过加热模压使壳体元件35c内的气体排除，并使以上无机胶、釉料或焊料连接材料固化，以提升壳体元件35c作为加热器30的外壳的强度。
在又一些实施中，壳体元件35c与电阻加热元件31c之间通过绝缘层或绝缘填料实现电绝缘，或壳体元件35c自身的片材包括的绝缘材质提供绝缘；例如以上应力补偿层的材料，或者陶瓷或玻璃材质。
在图2所示的优选实施中，加热器30还包括：
法兰或固定座36c，围绕并结合于电极环33c上；法兰或固定座36c材质通常采用陶瓷或耐热有机物例如PEEK、铁氟龙；在装配中，气雾生成装置通过夹持或抵靠该法兰或固定座36c进而使加热器30稳定装配在气雾生成装置 内。
或者进一步图6示出了又一个变化实施例的加热器30的示意图；该实施例的加热器30包括：
基体32d，具有区段321d和区段322d；区段321d是锥形形状，并界定加热器30的自由前端310d；区段322d是外径基本恒定的棒状或杆状或柱状形状；
电阻加热元件31d，例如电阻加热线圈，围绕基体32d的区段322d布置；
电阻加热元件31d的上端在连接位置B1处通过焊接或压接等方式直接与第一导线341d连接导通；电阻加热元件31d的下端在连接位置B2处通过焊接或压接等方式直接与第二导线342d连接导通；
壳体元件35c，围绕电阻加热元件31d和基体32d的区段322d；壳体元件35d是避开基体32d的区段321d的。在装配后，由壳体元件35d将电阻加热元件31d限制和保持在基体32d的区段322d上，防止电阻加热元件31d松脱或移动。同时，在装配后由壳体元件35d至少部分界定加热器30的外表面。
在一些实施中，壳体元件35d是由以上0.5～30μm的厚度的箔片或薄片卷绕形成的。以及，箔片或薄片是金属箔(如不锈钢箔、NiCr合金箔)和非金属箔(如陶瓷/玻璃流延片)。在更加优选的实施中，形成壳体元件35d的箔片或薄片是采用导热系数高的金属或合金的箔片或薄片；例如金、银、铜、铝或它们的合金的箔片或薄片。
以上加热器30由箔片或薄片卷绕的壳体元件35d至少部分界定加热器30的外壳或外表面，可以使热流在电阻加热元件31d表面旋转，可以更好地均衡加热器30表面的温场分布。
或者更进一步地在一些实施中，加热器30的卷绕后的壳体元件35c/35d的表面进一步还可以形成有保护涂层，例如更光滑的水性纳米陶瓷涂层、或者更光滑的玻璃釉层；以阻止源自气溶胶生成制品A的有机物或冷凝液在壳体元件35c/35d的表面的粘附或产生腐蚀。
