正如背景技术中所述，传统采用电磁加热方式的电子雾化装置，存在起雾慢的问题，给用户带来了不好的使用体验。
发明人研究发现，出现上述问题的根本原因在于：传统的电子雾化装置，所采用的电磁加热线圈，在轴向上各处的螺距相等，使得发热体正对电磁加热线圈在轴向上中间位置的部分的温度较高。而气溶胶生成基质通过发热体加热而雾化，由于发热体的高温位置相对靠中，导致气溶胶生成基质的芯体的上部并不具有被优先升温而雾化的优势，从而导致出现上述第一口起雾慢及雾量小的问题。
基于上述问题，参阅图1，本申请提供一种电子雾化装置100，电子雾化装置100可用于加热雾化花叶类、草本类、合成类的液态、固态或膏状的气溶胶生成基质300。
参阅图2，电子雾化装置100包括加热组件200，加热组件200包括发热体10及套接于发热体10外的电磁加热线圈20，电磁加热线圈20在轴向上螺旋延伸，发热体10在径向上与电磁加热线圈20至少部分相对。电磁加热线圈20通电产生磁场，发热体10处于电磁加热线圈20所产生的磁场中而发热，以用于加热气溶胶生成基质300。具体地，电磁加热线圈20在轴向上具有一中间位置，发热体10在轴向上延伸至中心位置的两侧，即为电磁加热线圈20处于中间位置两侧的部分均对应设有发热体10。
参阅图2及图3，发热体10内设有一容纳腔11，发热体10在轴向上的一端开设有与容纳腔11连通的开口12。气溶胶生成基质300包括杆体301和设于杆体301内的芯体302，气溶胶生成基质300能够经开口12容纳于容纳腔11中。电磁加热线圈20通电产生磁场，发热体10处于上述磁场中而发热，由于气溶胶生成基质300的芯体302容纳于容纳腔11中，此时，发热体10将热量传递至气溶胶生成基质300的芯体302，气溶胶生成基质300的芯体302温度升高而雾化形成气溶胶。
一实施例中，在轴向上，发热体10的两端均突伸出电磁加热线圈20，以使电磁加热线圈20在轴向上的各处均对应设有发热体10，以减小能量的浪费。当然，在另一些实施例中，也可以设置发热体10在轴向上的长度小于电磁加热线圈20在轴向上的长度，这样，发热体10在轴向上的至少一端面位于电磁加热线圈20内。
气溶胶生成基质300的芯体302在轴向上的尺寸，小于容纳腔11的尺寸，这样，保证整个芯体302容纳于容纳腔11中，芯体302的各部分均与发热体10接触而被发热体10加热雾化。
具体地，当气溶胶生成基质300容纳于容纳腔11内时，芯体302靠近开口12的端面位于电磁加热线圈20内。应当理解的是，在另一些实施例中，当气溶胶生成基质300容纳于容纳腔11内时，芯体302靠近开口12的端面也可以与电磁加热线圈20平齐，在此不作限定。
加热组件200还包括安装架30，电磁加热线圈20螺旋设于安装架30外，发热体10设于安装架30内。如此，便于发热体10与电磁加热线圈20的装配与固定。
参阅图4，安装架30具有沿轴向螺旋延伸的定位槽31，电磁加热线圈20嵌设于定位槽31中，具体地，定位槽31为仿制电磁加热线圈20的形状而制备的仿形槽，以便于电磁加热线圈20牢固固定于安装架30上。
参阅图3，加热组件200还包括磁屏蔽件40，磁屏蔽件40设于电磁加热线圈20外。一方面，磁屏蔽件40能够对电磁加热线圈20进行固定，磁屏蔽件40能够避免电磁加热线圈20向外界辐射电磁。具体地，磁屏蔽件40与电磁加热线圈20粘结固定。
参阅图5，电磁加热线圈20在轴向上具有多匝子线圈21，具体地，电磁加热线圈20通过至少一束导线束在轴向螺旋延伸而成，每束导线束包括至少两股导线，即为，每束导线束包括至少两根导线，每束导线束通过至少两股(两根)导线绞合而成。
参阅图6，每匝子线圈21在轴向上具有第一尺寸H，在径向上具有第二尺寸W，第一尺寸H大于第二尺寸W。
上述电磁加热线圈20，每匝子线圈21在径向上的尺寸小于在轴向上的尺寸，相对于现有技术中电磁加热线圈20的每匝子线圈21的截面为圆形(当电磁加热线圈20的截面为圆形时，每匝子线圈21的径向尺寸和轴向尺寸相等)的情况，具有如下优势：
1、减小了电磁加热线圈20在径向上的尺寸，从而减小了电子雾化装置100在径向上(横向空间)的尺寸，利于电子雾化装置100的小型化。
2、在整个电磁加热线圈20直径相同的情况下，外围周长较大，更加利于电磁加热线圈20的散热，降低电磁加热线圈20的温度和电磁加热线圈20损耗，提高了电磁加热线圈20的使用寿命。
3、在整个电磁加热线圈20直径相同的情况下，电磁加热线圈20在发热体10所在平面的正投影的投影面积较大，能够增加加热面积和提高磁场的均匀性。
同时，本实施例提供的电磁加热线圈20，通过至少一束导线束沿上述轴向螺旋延伸而成，且每束导线束包括至少两股导线，相对于现有技术中电磁加热线圈20通过扁平状的金属带材螺旋延伸而成的情况，能够减小电磁加热线圈20在高频电流下的交流电阻，降低电子雾化装置100自身能量的损耗。
一实施例中，每匝子线圈21的截面形状为长方形。由于长方形一组边的长度大于另一组边的长度，当设置每匝子线圈21的截面形状为长方形时，使长方形的一组长边沿轴向设置，一组短边沿径向设置，能够保证每匝子线圈21在轴向上的尺寸大于在径向上的尺寸，也即为保证第一尺寸H大于第二尺寸W。
另一实施例中，每匝子线圈21的截面形状为椭圆形。由于椭圆形具有一长轴和一短轴，当设置每匝子线圈21的截面形状为椭圆形时，使长轴沿轴向设置，短轴沿径向设置，能够保证每匝子线圈2121在轴向上的尺寸大于在径向上的尺寸，也即为保证第一尺寸H大于第二尺寸W。
可以理解的是，在另一些实施例中，每匝子线圈21的截面形状不局限于上述长方形和椭圆形，能够根据需要进行设定。
一实施例中，电磁加热线圈20由一束导线束沿沿轴向螺旋延伸而成，每束导线束包括导线的数量为15股-300股，每股导线的直径为0.02mm-0.5mm。具体地，每束导线束包括100股导线，每股导线的直径为0.1mm。在制备电磁加热线圈20时，首先将100股直径为0.1mm的导线绞合在一起形成一束导线束，再通过专门的设备将导线束压成需要的形状，最后将该导线束沿轴向螺旋延伸形成电磁加热线圈20。
另一实施例中，电磁加热线圈20由多束导线束沿轴向螺旋延伸而成，每束导线束包括导线的数量为15股-300股，每股导线的直径为0.02mm-0.5mm。具体地，电磁加热线圈20 由三束导线束沿轴向螺旋延伸而成，每束导线束包括100股导线，每股导线的直径为0.1mm。在制备电磁加热线圈20时，首先将100股直径为0.1mm的导线绞合在一起形成一束导线束，再将三束导线绞合在一起，并通过专门的设备将绞合在一起的导线束压成需要的形状，最后将压合成特定形状的三束导线束沿轴向螺旋延伸形成电磁加热线圈20。
当然，其他一些实施例中，对于电磁加热线圈20所包括的导线束的数量、每束导线束所包括的导线的股数以及每股导线的直径均不作具体限定。如在一些实施例中，电磁加热线圈20由两束导线束沿轴向螺旋延伸而成，每束导线束包括150股导线，每股导线的直径为0.05mm。
继续参阅图6，电磁加热线圈20在轴向上自一端到另一端包括依次相连的第一螺旋段22与第二螺旋段23。第一螺旋段22的任意相邻两匝子线圈21之间的螺距小于第二螺旋段23的任意相邻两匝子线圈21之间的螺距。
参阅图2，以图2中方向为例，电磁加热线圈20的轴向即为图2中的上下方向，径向即为图2中的左右方向。
开口12设于发热体10的上端，气溶胶生成基质300自上而下插入容纳腔11中，此时，气溶胶生成基质300的芯体302容纳于容纳腔11内。第一螺旋段22设于第二螺旋段23的上端。
这样，由于第一螺旋段22的任意相邻两匝子线圈21之间的螺距小于第二螺旋段23的任意相邻两匝子线圈21之间的螺距，相对于现有技术中等螺距设置的电磁加热线圈20，在通电时，电磁加热线圈20的磁感应强度发生改变，从而使得发热体10正对电磁加热线圈20上部的温度得以提高，则提高容纳于容纳腔11中芯体302的上部的升温速度，从而提高了电子雾化装置100第一口的起雾速度及起雾量，提升抽吸口感。
在此需要说明的是，上述相邻两匝子线圈21之间的螺距即为相邻两个子线圈21之间的轴向距离。
进一步，参阅图5及图6，第一螺旋段22的任意相邻两匝子线圈21之间的螺距相等，第二螺旋段23的任意相邻两匝子线圈21之间的螺距相等。这样，便于电磁加热线圈20的制备。应当理解的是，在另一些实施例中，还可以设置第一螺旋段22所包括的每相邻两匝子线圈21之间的螺距不等，或者部分相等，设置第二螺旋段23所包括的每相邻两匝子线圈21之间的螺距不等，或者部分相等。
一实施例中，第一螺旋段22所包括的子线圈21的匝数大于或等于第二螺旋段23所包括的子线圈21的匝数，以进一步提高电发热体10在轴向上上部的温度。当然，在另一些实施例中，也可以设置第一螺旋段22所包括的子线圈21的匝数小于第二螺旋段23所包括的子线圈21的匝数。
第一螺旋段22任意相邻两匝子线圈21之间的螺距选自0mm-4mm，第二螺旋段23 的任意相邻两匝子线圈21之间的螺距选自0.5mm-8mm。在此需要说明的是，对于第一螺旋段22的相邻两匝子线圈21之间的螺距及第二螺旋段23的相邻两匝子线圈21之间的螺距不作具体限定，可以依据需要选择。
一实施例中，参阅图7，电磁加热线圈20还包括第三螺旋段24，第二螺旋段23连接第一螺旋与第三螺旋段24。第三螺旋段24的任意相邻两匝子线圈21之间的螺距小于第二螺旋段23的任意相邻两匝子线圈21之间的螺距。
这样，由于第一螺旋段22的任意相邻两匝子线圈21之间的螺距及第三螺旋段24的任意相邻两匝子线圈21之间的螺距均小于第二螺旋段23的任意相邻两匝子线圈21之间的螺距，相对于现有技术中等螺距设置的电磁加热线圈20，在通电时，电磁加热线圈20的磁感应强度发生改变，使得发热体10正对电磁加热线圈20上部的温度得以提高，且在发热体10在轴向上中下各部分的温度差值减小，抽吸过程中雾量的衰减较慢，提高在抽吸过程中的雾量均匀性。
第三螺旋段24的任意相邻两匝子线圈21之间的螺距相等，以便于电磁加热线圈20的制备。应当理解的是，在另一些实施例中，还可以设置第三螺旋段24所包括的每相邻两匝子线圈21之间的螺距不等，或者部分相等，
进一步，第一螺旋段22任意相邻两匝子线圈21之间的螺距小于或等于第三螺旋段24的任意相邻两匝子线圈21之间的螺距。当然，在另一些实施例中，也可以设置第一螺旋段22任意相邻两匝子线圈21之间的螺距大于第三螺旋段24的任意相邻两匝子线圈21之间的螺距，或者第一螺旋段22的部分相邻两匝子线圈21之间的螺距大于第三螺旋段24的部分相邻两匝子线圈21之间的螺距。
一实施例中，第一螺旋段22所包括的子线圈21的匝数，大于或等于第三螺旋段24所包括的子线圈21的匝数，以进一步提高电发热体10在轴向上上部的温度。当然，在另一些实施例中，也可以设置第一螺旋段22所包括的子线圈21的匝数，小于第三螺旋段24所包括的子线圈21的匝数。
第三螺旋段24的任意相邻两匝线圈之间的螺距选自0mm-4mm。在此需要说明的是，对于第三螺旋段24的相邻两匝子线圈21之间的螺距不作具体限定，可以依据需要选择。
为了更清楚地理解本申请，下面以一实施例与一对比例相对比，以进行说明。
在实施例和对比例中均设置:
电磁加热线圈20在轴向上的尺寸为18mm，芯体302的长度为20mm，芯体302全部容纳于发热体10的容纳腔11中，且芯体302的上端面高出电磁加热线圈20上端面3mm。每匝子线圈21在轴向上的尺寸为1.6mm。
参阅图8，图8中三个圆圈，从上自下依次代表发热体20理论上形成的高温场、中温场和低温场。
对比例中：电磁加热线圈20为均匀绕制线圈，即为电磁加热线圈20的每相邻两个子线圈21之间的螺距相等。
由图8可知，对比例中，发热体10的理论高温场的中心在电磁加热线圈20轴向的中心位置，即为在距离芯体302的上端面靠下6mm处。
实施例中：电磁加热线圈20包括第一螺旋段22和第二螺旋段23，第一螺旋段22在轴向上的尺寸为8mm，第二螺旋段23在轴向上的尺寸为10mm。第一螺旋段22包括5匝子线圈21，第一螺旋段22的每相邻两匝子线圈21在轴向上的间距为0。第二螺旋段23包括3匝子线圈21，第二螺旋段23的每相邻两匝子线圈21在轴向上的间距相等，且均接近2mm。
由图8可知，实施例中，发热体10的理论高温场的中心在电磁加热线圈20轴向的中心位置靠上，即为在距离芯体302的上端面靠下3mm。
经过上述对比可以发现，采用本申请实施例中提供的电磁加热线圈20，能够使发热体10上部的温度得以提高，从而能够保证电子雾化装置100第一口起雾快，具有良好的抽吸体验。
本申请另一实施例还提供一种上述电子雾化装置100所包括的加热组件200。
本申请又一实施例还提供一种上述加热组件200所包括的电磁加热线圈20。电磁加热线圈20在轴向上具有多匝子线圈21，且在轴向上自一端到另一端包括依次相连的第一螺旋段22和第二螺旋段23，第一螺旋段22的任意相邻两匝子线圈21之间的螺距小于第二螺旋段23的任意相邻两匝子线圈21之间的螺距。这样，相对于现有技术中螺距均匀的电磁加热线圈20，通电产生磁场时，处于磁场中的发热体10发热，发热体10正对第一螺旋段22的温度得以提高，以便气溶胶生成基质300的芯体302接近用户抽吸端的一端升温较快，从而使电子雾化装置100起雾快，提升用户体验。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围，其均应涵盖在本申请的权利要求和说明书的范围当中。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
