为了说明本申请所提供的技术方案，以下结合具体附图及实施例进行详细说明。
参阅图1和图2，本申请实施例提供了一种电子雾化装置，电子雾化装置包括电池杆（未图示）和雾化器100，电池杆内设有供电电源和控制电路，控制电路用于控制供电电源为雾化器100进行供电，雾化器100包括油杯和安装到油杯的雾化组件。
油杯10的一端开口，另一端设有吸气口12以供用户抽吸。油杯10设置吸气口12的一端内壁在吸气口12的边缘处形成有伸入油杯10内部的导气件13，导气件13的内部与吸气口12连通。导气件13与油杯10的内壁之间形成储液腔11以储存雾化液。本实施例中，导气件13与油杯10为一体成型的整体。
雾化组件包括底部组件、顶部组件和发热组件200，顶部组件包括安装到油杯10的开口端并与油杯10内壁密封连接的密封件20。底部组件包括安装到油杯10的开口端的底座40、插入到底座40并给发热组件200供电的两个电极50。本实施例中，顶部组件还包括支架30，支架30的一端（即支架30的底端）套装到底座40的顶端，支架30的另一端（即支架30的顶端）安装到密封件20内。支架30底端的内部形成用于收容发热组件200的空间，从而使发热组件200被夹持定位在支架30与底座40之间。
具体的，密封件20的外壁沿其轴向形成有若干环状的凸起22，若干凸起22弹性抵顶到油杯10的内壁，从而实现密封件20与油杯10的内壁之间的密封连接。密封件20设有进液口21，支架30设有进液通道31与对应的进液口21连通，从而使得发热组件200与油杯10的储液腔11连通，使储液腔11内的雾化液可通过进液通道31引导到发热组件200。
底座40具有贯通其底端和顶端的两个安装通道41，两个安装通道41分别靠近底座40的两侧。两个电极50分别从底座40往顶部组件的方向插入到两个安装通道41内，以将两个电极50安装到底座40。两个电极50的极性相反。两个电极50的底端可以与底座40的底端平齐，两个电极50的顶端分别凸出于底座40的顶端。
发热组件200包括依次叠置到底座40顶端的导油体60、发热元件70和支撑体80。发热元件70被支撑体80和导油体60夹持及定位，支撑体80对发热元件70起到支撑作用。导油体60安装到支架30的底端内并紧贴支架30底端内的底部，导油体60与进液通道31相接，采用多孔陶瓷材料或者吸油棉制成，因此导油体60内含有大量的微孔结构而具有一定的孔隙率，能够将储液腔11中的雾化液吸入并传输至与发热元件70接触的底面上，以使发热元件70对所接触的雾化液进行加热雾化。在其他实施例中，发热组件200的发热元件70也可以设置于导油体60的上表面，即导油体60设置于发热元件70和支撑体80之间，由发热元件70直接与进液通道31相接。
在一个实施例中，导油体60的外壁与支架30底端的内壁为过盈配合。发热元件70的两端设有两个固定部71，支撑体80的两端分别设有安装孔82，两个电极50的顶端分别与支撑体80两端的安装孔82连接，并分别抵接或通过焊接或铆接等方式连接于发热元件70的两端固定部71上实现电连接。通过该种结构，本申请的发热组件200的支撑体80、发热元件70和导油体60是依次叠置到底座40的顶端的，在进行组装发热组件200时，可将支撑体80、发热元件70进行依次装配到底部组件的底座40的顶端；随后装配电极50，使电极50与发热元件70的固定部71实现电连接，再将导油体60装配到顶部组件的支架30的底端内后将支架30的底端套装到底座40的顶端，实施本申请可通过自动化设备进行自动化、批量化装配，提高了生产效率，降低了成本。
在现有技术中，片状发热网通常是采用多根第一发热丝和多个第二发热丝相互交错形成的网状结构或者镂空结构，且片状发热网所形成的网孔一般为菱形孔，发热时菱形孔的尖角部位热量堆叠集中，热量集中会导致发热网上的油膜瞬间被加热，容易引起炸油发生，长时间热量过热也容易导致供油不足引起的糊芯，给用户不好的体验。
请结合图3所示，发热元件70包括串接在两个固定部71之间的发热体，发热体包括沿第一方向间隔并列设置并依次通过第一连接部73串联设置的至少两个发热单元72，本申请以五个发热单元72进行举例说明；每一发热单元72为沿第二方向延伸的长条状结构。其中，第一方向和第二方向相互垂直，即第一方向为图3中的横向，第二方向为图3中的纵向，每个发热单元72发热时的总体发热量大致相同，从而使发热体在第一方向上的发热量均匀分布。
在本实施例中，发热元件70是由镍铬、铁铬铝或不锈钢等金属材质制成的片状结构，其材料可根据实际情况进行选择，采用冲裁或刻蚀等方式制作，发热元件70的厚度为0.05~0.1mm，在一些实施例中，发热元件70的厚度为0.06~0.08mm，发热元件70的电阻为0.5~2Ω，在一些实施例中，发热元件70的电阻为1Ω。
具体地，每一发热单元72的中部开设有第一通孔721，以形成环形的第一发热线路。多个第一连接部73处于同一直线上，并与第一方向平行，且平分发热单元72；所形成的第一发热线路由第一连接部73分隔上下对称的两个部分，两个部分相互并联于相邻两个第一连接部73之间，每个部分包括相对设置且沿第二方向延伸的第一发热段722以及连接于两个第一发热段722之间的第二发热段723，第一发热段722和第二发热段723大致垂直，相比于现有开设菱形孔的发热网结构，本实施例发热单元72避免了尖角结构的存在，且发热单元72之间间隔设置，热量可在发热体上沿多个发热单元72均匀产生，可有效提高导油体60与发热体的接触面积，有利于热量分布均匀，避免了尖角部位热量堆叠集中而引起炸油发生。
在一些实施例中，第一通孔721为圆孔、长圆孔、椭圆孔或具有倒圆角的条形孔，示例性的，第一通孔721为具有倒圆角的条形孔，从而使第一发热段722和第二发热段723之间圆滑过渡，以提高第一发热线路发热时的热量均匀性。
在一个实施例中，每一发热单元72的两端还分别开设有至少一个第二通孔724，发热单元72两端上的第二通孔724相对第一通孔721对称设置，以形成与第一发热线路连接的第二发热线路；也就是说，每个发热单元72的两个第二发热线路相对该第一连接部73所处直线相互对称；如此使得发热体在发热时位于该直线两侧的热量相同，有利于热量的整体分布均匀。
结合图3所示，本实施例以发热单元72的两端分别开设一个第二通孔724进行举例说明，第二通孔724所形成的第二发热线路包括两个相对设置且沿第二方向延伸的第三发热段725以及连接于两个第三发热段725一端之间的固定段726，两个第三发热段725远离固定段726的一端连接于第一发热段722与第二发热段723之间的连接处，因此，第二发热线路是与第二发热段723并联于两个第一发热段722之间的，以使发热单元72发热时，第一发热线路的发热量大于第二发热线路的发热量，并且，第一发热段722的发热量大于第二发热段723的发热量，第三发热段725的发热量大于固定段726的发热量，从而形成发热体在发热时沿第二方向的中部位置发热量较大，沿第二方向两侧的边缘位置发热量较小的结构。在其他实施例中，发热单元72的两端还可开设两个或两个以上数量的第二通孔724，发热单元72一端中的各第二通孔724可大小相同或由发热单元72中部至端部方向依次缩小。
在实际应用中，当发热元件70设于支撑体80上时，发热单元72的两端即两个固定段726凸出于支撑体80的边缘处，两个固定段726的末端分别朝向支撑体80方向弯折并夹持固定于支撑体80的两侧，以使支撑体80支撑和更好地固定发热元件70，使发热元件70的发热体部分不易变形和位移。
在一些实施例中，第二通孔724为圆孔、长圆孔、椭圆孔或具有倒圆角的条形孔，示例性的，第二通孔724为具有倒圆角的条形孔，从而使第三发热段725和固定段726之间以及与第一发热线路之间圆滑过渡，以提高第二发热线路发热时的热量均匀性。另外，第二通孔724在支撑体80表面上的投影面积全部位于支撑体80表面的边缘内，即第三发热段725不随着固定段726而发生弯折。
第一连接部73的宽度大于第一发热线路（即第一发热段722）的宽度，以使发热体通电时第一连接部73的电阻低于发热单元72的电阻，如此可避免热量集中于第一连接部73的位置；而第三发热段725的宽度被构成使其发热量以接近第一发热段722的发热量为佳，有利于热量的整体分布均匀。
在本实施例中，固定部71上围绕于与电极50抵接的区域开设有多个第三通孔711。第三通孔711的作用是增加固定部71的面积，以提高发热元件70在导油体60和支撑体80之间的连接强度，且发热体的整体电阻率大于固定部71的电阻率，以减少固定部71的功耗。
发热体的两端分别通过一第二连接部74与两个固定部71连接，第二连接部74开设有第四通孔741；如此可使第二连接部74在第二方向上的宽度大于第一连接部73在第二方向上的宽度，保证了发热体与固定部71之间的连接强度。
在一个替换实施例中，如图4所示，本实施例发热元件70与图3所示实施例发热元件70的区别在于：发热元件70的发热体包括沿第一方向间隔并列设置并相互并联的至少两个发热单元72，发热单元72的结构与上述实施例相同，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。需要说明的是，此时第一方向为图4中的纵向，第二方向为图4中的横向，每个发热单元72发热时的总体发热量大致相同，从而使发热体在第一方向上的发热量均匀分布。在一些实施例中，本实施例发热元件70可根据实际情况需要，将发热体数量设为多个，多个发热体相互串联在两个固定部71之间。
在一个实施例中，支撑体80为一致密陶瓷件，可以理解地，支撑体80还可以是例如多孔陶瓷件、硅胶件、外表面不导电的金属件等等；支撑体80设有与发热体对应的镂空孔81，镂空孔81与底座40顶端设置的雾化腔42对应连通，底座40的底端设有进气通道44，雾化腔42的底部设有与进气通道44连通的进气孔43，从而外部空气可经进气通道44和进气孔43进入到雾化腔42内，和经发热元件70加热雾化后的气溶胶进行混合。
支架30底端内的底部和支架30的顶端之间设有进液通道31，进液通道31为两个，两个进液通道31分别大致与两个固定部71对应。在一些实施例中，进液通道31的截面由导油体60向靠近储液腔11的方向逐渐增大以提高进液速度。
支架30的顶端设有安装位33，安装位33的底部设有过气腔32，支架的30相对两侧设有与过气腔32连通的过气孔，两个过气孔分别从底座40外侧与雾化腔42连通。密封件20的顶端内壁形成有安装部23，安装部23安装到安装位33内。密封件20的顶端设有套接孔24，套接孔24贯通安装部23的底端。导气件13的远离吸气口12的一端安装到套接孔24内并与套接孔24的内壁密封连接，导气件13的内部与过气腔32连通。当用户在吸气口12处抽吸时，进入到雾化腔42内的外部空气和经发热元件70加热雾化后的气溶胶混合后可经过过气腔32、导气件13的内部进入到吸气口12，从而最终被用户抽吸。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其它实施例的相关描述。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
