背景技术
气溶胶是一种由固体或液体小质点分散并悬浮在气体介质中形成的胶体分散体系，气溶胶可通过呼吸系统被人体吸收，为用户提供一种新型的替代吸收方式。例如，可对草本类或膏类的气溶胶生成基质烘烤加热而产生气溶胶的电子雾化装置，应用于不同领域中，为用户递送可供吸入的气溶胶，替代常规的产品形态及吸收方式。
电子雾化装置利用加热组件对气溶胶生成基质进行加热，以产生供用户吸食的气溶胶。而针对采用电磁加热方式的电子雾化装置，其加热组件包括电磁加热线圈及发热体，电磁加热线圈通电产生磁场，发热体位于电磁加热线圈产生的磁场中而升温，气溶胶生成基质与发热体接触，发热体将气溶胶生成基质加热雾化。

参阅图1，图1示出了本发明一实施例中的加热机构100的结构示意图，本发明一实施例提供了的加热机构100，包括发热体10和电磁加热线圈30，
发热体10内形成有沿自身纵长方向延伸的容置腔11，容置腔11用于容置气溶胶生成基质。电磁加热线圈30套设于发热体10外，当电磁加热线圈30通电时利用电磁感应原理，使发热体10发热，进而加热发热体10内部容置的气溶胶生成基质，形成供用户食用的气溶胶。
并且，在发热体10的纵长方向上，电磁加热线圈30的轴向中心与容置腔11纵长方向的中心错位。电磁加热线圈30通电后，能够在对应自身轴向中心的位置处形成磁感应最强的加热电场，发热体10对应电磁加热线圈30的中心处热量最高，而且该位置与容置腔11的纵向中心在纵向上错位，相当于该热量最高处位于容置腔11纵向中心的一侧，对于容置腔11内的气溶胶生成基质该高温场可分布到顶部，便可使气溶胶生成基质从顶部快速起雾，且烟雾量大。
进一步地，发热体10具有沿自身纵长方向排布的高温区12和中温区14，电磁加热线圈30的轴向中心位于高温区12。也就是说，将发热体10在自身纵长方向上划分为高温区12和中温区14，电磁加热线圈30的轴向中心处于高温区12所在的范围，进而使电磁加热线圈30的磁感应最强的位置偏移值高温区12，且使发热体10内气溶胶生成基质的顶部位于高温区12，可利用高温区12先加热雾化气溶胶生成基质的顶部，进而能够快速起雾。
可以理解地，加热机构100应用于电子雾化装置中，用户使用电子雾化装置时，气流沿中温区14至高温区12的方向流动，位于高温区12的气溶胶生成基质受到的温度更高，可以先被雾化后随着气流流出，供用户食用。
进一步地，容置腔11沿自身纵长方向的中心，位于高温区12和中温区14的分界线上。也就是说，电磁加热线圈30的轴向中心位于容置腔11沿自身纵长方向中心的上方，容置 腔11沿自身纵长方向的中心以上为高温区12，容置腔11沿自身纵长方向中心以下的至少部分为中温区14，如此界定高温区12和中温区14。
一些实施例中，发热体10还具有低温区16，中温区14连接于低温区16和高温区12之间，电磁加热线圈30朝向发热体10的正投影覆盖高温区12和中温区14，且与低温区16错位。也就是说，电磁加热线圈30套设于高温区12和中温区14外，不套设于低温区16外，这样抬高电磁加热线圈30，使电磁加热线圈30的轴向中心上移到高温区12。
同时，沿发热体10的纵长方向依次布设低温区16、中温区14及高温区12，形成高、中、低温度梯度场。当加热机构100启动加热时，电磁加热线圈30使发热体10的高温区12热量最高，局部加热气溶胶生成基质以快速起雾，同时对中温区14及低温区16进行预热，当高温区12雾化完毕后，中温区14介入，继而到低温区16，最终完成气溶胶生成基质整体的雾化。如此，高中低梯度温度分布，使气溶胶生成基质能够快速起雾，持续雾化，且雾化一致性较佳，气溶胶生成基质能够被均匀雾化。
一些实施例中，在发热体10的纵长方向上，电磁加热线圈30的轴向中心与容置腔11纵长方向的中心之间的错位高度为3.5mm-4.5mm，这样将电磁加热线圈30的轴向中心上移3.5-4.5mm，以有效提高发热体10上部的温度，形成高温区12。可选地，在发热体10的纵长方向上，电磁加热线圈30的轴向中心与容置腔11纵长方向的中心之间的错位高度为4mm。
进一步地，容置腔11用于容置长度为20mm的气溶胶生成基质，电磁加热线圈30的轴向长度为18mm，电磁加热线圈30的顶端高处气溶胶生成基质的顶端3mm，以上述尺寸设计气溶胶生成基质和电磁加热线圈30，使电磁加热线圈30高出气溶胶生成基质3mm，进而使电磁加热线圈30的轴向中心高出气溶胶生成基质的纵向中心4mm，在气溶胶生成基质的顶部形成高温区12，提高气雾速度。
一些实施例中，加热机构100还包括安装架50，电磁加热线圈30螺旋设于安装架50 外，发热体10设于安装架50内。如此，便于发热体10与电磁加热线圈30的装配与固定。
安装架50具有沿轴向螺旋延伸的定位槽，电磁加热线圈30嵌设于定位槽中，具体地，定位槽为仿制电磁加热线圈30的形状而制备的仿形槽，以便于电磁加热线圈30牢固固定于安装架50上。
可选地，加热组件还包括磁屏蔽件，磁屏蔽件设于电磁加热线圈30外。一方面，磁屏蔽件能够对电磁加热线圈30进行固定，磁屏蔽件能够避免电磁加热线圈30向外界辐射电磁。具体地，磁屏蔽件与电磁加热线圈30粘结固定。
在上述任一实施例中，电磁加热线圈30在轴向上具有多匝子线圈，多匝子线圈均匀间隔绕设，即电磁加热线圈30中任意相邻两个子线圈之间的螺距相同，以均匀螺旋绕设电磁加热线圈30，使电磁加热线圈30形成的磁场在轴向上均匀分布，使电磁加热线圈30的磁感应最强处位于电磁加热线圈30的轴向中心处，进而可通过抬高电磁加热线圈30来形成位于发热体10顶部的高温区12。
进一步地，电磁加热线圈30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。
具体到本实施例中，加热机构100包括发热体10和电磁加热线圈30，发热体10内形成有沿自身纵长方向延伸的容置腔11，容置腔11用于容置气溶胶生成基质。电磁加热线圈30套设于发热体10外，在发热体10的纵长方向上，电磁加热线圈30的轴向中心与容置腔11纵长方向的中心错位，且在发热体10上形成沿自身纵长方向排布的高温区12、中温区14和低温区16，中温区14连接于低温区16和高温区12之间，电磁加热线圈30朝向发热体10的正投影覆盖高温区12和中温区14且与低温区16错位。也就是说，电磁加热线圈30套设于高温区12和中温区14外，不套设于低温区16外，这样抬高电磁加热线圈30，使电磁加热线圈30的轴向中心上移到高温区12。
同时，沿发热体10的纵长方向依次布设低温区16、中温区14及高温区12，形成高、中、低温度梯度场。当加热机构100启动加热时，电磁加热线圈30使发热体10的高温区12热量最高，局部加热气溶胶生成基质以快速起雾，同时对中温区14及低温区16进行预热，当高温区12雾化完毕后，中温区14介入，继而到低温区16，最终完成气溶胶生成基质整体的雾化。如此，高中低梯度温度分布，使气溶胶生成基质能够快速起雾，持续雾化，雾化一致性较佳，气溶胶生成基质能够被均匀雾化。
本发明一实施例中，还提供一种电子雾化装置，包括上述加热机构100。加热机构100，包括发热体10和电磁加热线圈30，
发热体10内形成有沿自身纵长方向延伸的容置腔11，容置腔11用于容置气溶胶生成基质。电磁加热线圈30套设于发热体10外，当电磁加热线圈30通电时利用电磁感应原理，使发热体10发热，进而加热发热体10内部容置的气溶胶生成基质，形成供用户食用的气溶胶。
并且，在发热体10的纵长方向上，电磁加热线圈30的轴向中心与容置腔11纵长方向的中心错位。电磁加热线圈30通电后，能够在对应自身轴向中心的位置处形成磁感应最强的加热电场，发热体10对应电磁加热线圈30的中心处热量最高，而且该位置与容置腔11的纵向中心在纵向上错位，相当于该热量最高处位于容置腔11纵向中心的一侧，对于容置腔11内的气溶胶生成基质该高温场可分布到顶部，便可使气溶胶生成基质从顶部快速起雾，且烟雾量大。
一些实施例中，电子雾化装置还包括吸嘴(图未示)，吸嘴装配于加热机构100上，且电磁加热线圈30的轴向中心相对容置腔11纵长方向的中心向靠近吸嘴的上方错位。
其中，吸嘴为用户抽吸时直接接触的部件，一般含在嘴里向吸嘴内部吸气，此时便可将电子雾化装置内加热产生的气溶胶生成基质吸入口中。电磁加热线圈30的轴向中心相 对容置腔11纵长方向的中心向靠近吸嘴的上方错位，相当于使电磁加热线圈30向靠近吸嘴的上方抬高，以将电磁加热线圈30的轴向中心上移至靠近吸嘴，以快速加热容置腔11内溶胶生成基质靠近吸嘴的顶部，提高起雾速度。
进一步地，发热体10具有沿自身纵长方向排布的高温区12和中温区14，电磁加热线圈30的轴向中心位于高温区12。也就是说，将发热体10在自身纵长方向上划分为高温区12和中温区14，电磁加热线圈30的轴向中心处于高温区12所在的范围，进而使电磁加热线圈30的磁感应最强的位置偏移值高温区12，且使发热体10内气溶胶生成基质的顶部位于高温区12，可利用高温区12先加热雾化气溶胶生成基质的顶部，进而能够快速起雾。
具体地，容置腔11沿自身纵长方向的中心，位于高温区12和中温区14的分界线上。也就是说，电磁加热线圈30的轴向中心位于容置腔11沿自身纵长方向中心的上方，容置腔11沿自身纵长方向的中心以上为高温区12，容置腔11沿自身纵长方向中心以下的至少部分为中温区14，如此界定高温区12和中温区14。
一些实施例中，发热体10还具有低温区16，中温区14连接于低温区16和高温区12之间，电磁加热线圈30朝向发热体10的正投影覆盖高温区12和中温区14，且与低温区16错位。也就是说，电磁加热线圈30套设于高温区12和中温区14外，不套设于低温区16外，这样抬高电磁加热线圈30，使电磁加热线圈30的轴向中心上移到高温区12。
同时，沿发热体10的纵长方向依次布设低温区16、中温区14及高温区12，形成高、中、低温度梯度场。当加热机构100启动加热时，电磁加热线圈30使发热体10的高温区12热量最高，局部加热气溶胶生成基质以快速起雾，同时对中温区14及低温区16进行预热，当高温区12雾化完毕后，中温区14介入，继而到低温区16，最终完成气溶胶生成基质整体的雾化。如此，高中低梯度温度分布，使气溶胶生成基质能够快速起雾，持续雾化，雾化一致性较佳，气溶胶生成基质能够被均匀雾化。
一些实施例中，在发热体10的纵长方向上，电磁加热线圈30的轴向中心与容置腔11 纵长方向的中心之间的错位高度为3.5mm-4.5mm，这样将电磁加热线圈30的轴向中心上移3.5-4.5mm，以有效提高发热体10上部的温度，形成高温区12。可选地，在发热体10的纵长方向上，电磁加热线圈30的轴向中心与容置腔11纵长方向的中心之间的错位高度为4mm。
具体地，容置腔11用于容置长度为20mm的气溶胶生成基质，电磁加热线圈30的轴向长度为18mm，电磁加热线圈30的顶端高处气溶胶生成基质的顶端3mm，以上述尺寸设计气溶胶生成基质和电磁加热线圈30，使电磁加热线圈30高出气溶胶生成基质3mm，进而使电磁加热线圈30的轴向中心高出气溶胶生成基质的纵向中心4mm，在气溶胶生成基质的顶部形成高温区12，提高气雾速度。
一些实施例中，加热机构100还包括安装架50，电磁加热线圈30螺旋设于安装架50外，发热体10设于安装架50内。如此，便于发热体10与电磁加热线圈30的装配与固定。安装架50具有沿轴向螺旋延伸的定位槽，电磁加热线圈30嵌设于定位槽中，具体地，定位槽为仿制电磁加热线圈30的形状而制备的仿形槽，以便于电磁加热线圈30牢固固定于安装架50上。
