雾化器是通过加热雾化介质而生成气溶胶的装置。加热不燃烧(Heat No Burning，HNB)式雾化装置是通过加热含有雾化介质的雾化基质而生成气溶胶的装置。
目前，加热不燃烧式雾化器的加热方式为接触式加热，即利用发热体传导热量给雾化基质而使雾化介质吸热后雾化形成气溶胶。然而，目前的雾化基质的导热系数低，这使得雾化介质雾化响应速度慢；并且由于发热体加热雾化基质时，雾化基质靠近发热体的部分与远离发热体的部分之间温差大，容易存在雾化基质受热不均匀而影响抽吸口感。

一种气溶胶生成品，包括包覆层和雾化部，所述雾化部位于所述包覆层的内部且由所述包覆层包裹，所述雾化部的材料为上述的雾化基质。
一种电子雾化器，包括壳体和电源，所述壳体具有用于容纳上述的气溶胶生成品的容纳腔，所述电源位于所述壳体内，所述电源为所述气溶胶生成品的雾化部的雾化供电，在所述气溶胶生成品位于所述容纳腔中时，所述雾化部能与所述电源电连接而雾化形成气溶胶。

上述雾化基质100的制备方法简捷，利于工业化生产。
此外，请参阅图2，本申请一实施方式还提供了一种气溶胶生成品10，该 气溶胶生成品10包括包覆层11和雾化部12，雾化部12位于包覆层11的内部且由包覆层11包裹，雾化部12的材料为上述任一实施例的雾化基质100。
上述气溶胶生成品10的雾化部12采用上述雾化基质100制成，通过该雾化部12作为发热电阻自发热而雾化形成气溶胶。与传统依赖于发热体传导热量的气溶胶生成品相比，上述气溶胶生成品10自发热而发热速度快且发热均匀，升温和降温速度快，可实现即抽即停，改善了由于雾化部受热不均匀而导致的口感不一致和雾化部的利用率较低的问题，同时也改善了由于发热速度慢导致的雾化响应速度慢的问题。
在一些实施例中，气溶胶生成品10呈柱状或片状。可以理解的是，其他实施例中，气溶胶生成品10的形状不限于上述，还可以根据具体情况进行调整。
具体地，包覆层11作为雾化部12的外包装。在一些实施例中，包覆层11为包装纸和塑料中的至少一种。可以理解的是，包覆层11的材料不限于上述。在一些实施中，雾化部12为柱状，对应的，包覆层11呈筒状，气溶胶生成品10也呈柱状。在其中一个实施例中，雾化部12的横截面沿雾化部12的中心轴逐渐增大或减小，雾化部12的纵截面为等腰梯形。在图2所示的实施例中，雾化部12的纵截面呈等腰梯形，包覆层11的纵截面为位于雾化部12两侧的三角形。可以理解的是，雾化部12、包覆层11和气溶胶生成品10的形状不限于上述，还可以根据具体情况进行调整。

在一些实施例中，雾化部12的电阻为0.4Ω～2Ω。将雾化部12的电阻按照上述设置，可以适配目前的雾化器的发热电路；按照上述设置雾化部12的电阻适宜于雾化介质110雾化。在一个可选地具体示例中，雾化部12的电阻为0.5Ω、1Ω、1.5Ω或1.8Ω。可以理解的是，在其他实施例中，雾化部12的电阻可以根据雾化基质100的种类和雾化基质100的含量进行调整。

在一些实施例中，雾化部12由一种雾化基质100形成。也即是，雾化部12中的导电材料120均匀分布。
请再次参阅图2，在一些实施例中，气溶胶生成品10还包括嘴件13，嘴件13用于抽吸雾化部12产生的气溶胶。可选地，部分嘴件13位于包覆层11的内部且由包覆层11包裹。此时，包覆层11还作为整个气溶胶生成品10的外包装。在其中一个实施例中，气溶胶生成呈柱状，气溶胶生成品10包括在包覆层11的中心轴上依次布置且由包覆层11限定的雾化部12和嘴件13。雾化部12与嘴件13之间有间隔。进一步地，嘴件13的内部还设置有过滤材料(例如醋酸纤 维)。更进一步地，雾化部12与嘴件13之间还设置有气溶胶冷却元件，以冷却气溶胶。可以理解的是，在一些实施例中，包覆层11只包覆雾化部12，冷却元件、嘴件13等由位于包覆层11外的包装层包裹。
在一些实施例中，气溶胶生成品10还包括用于将雾化部12与电源22电连接的电极结构。具体地，电极结构包括第一电极和与第一电极间隔的第二电极，第一电极用于与电源22的正极电连接，第二电极用于与电源22的负电极24电连接。在其中一个实施例中，第一电极的一端与雾化部12直接接触(例如位于雾化部12中)，另一端凸出于雾化部12；第二电极的一端也与雾化部12直接接触(例如位于雾化部12)中，另一端也凸出于雾化部12。可以理解的是，在一些实施例中，气溶胶生成品10不包括电极结构。此时，雾化部12通过与电子雾化器的电连接件直接接触而与电源22电连接。
此外，请参阅图4(图4中的虚线箭头代表气流方向)，本申请还提供了一种电子雾化器，该电子雾化器包括壳体21和电源22。壳体21具有与上述任一实施例的气溶胶生成品10适配的容纳腔；电源22位于壳体21内，电源22为雾化部12的雾化供电；气溶胶生成品10位于容纳腔中时，雾化部12能与电源22电连接而雾化形成气溶胶。
具体地，电子雾化器包括正电极23和与正电极23间隔的负电极24。正电极23的一端与电源22电连接，另一端与气溶胶生成品10电连接；负电极24的一端与电源22电连接，另一端与气溶胶生成品10电连接，电源22、正电极23、气溶胶生成品10及负电极24形成回路。在图示的实施例中，正电极23的一端与电源22电连接，另一端与包覆层11电连接；负电极24的一端与电源22电连接，另一端与包覆层11电连接。电源22、正电极23、包覆层11、雾化部12及负电极24形成回路。
在一些实施例中，上述电子雾化器还包括温度感受器和控制器，温度感受器用于检测雾化部12的温度并将其检测结果反馈给控制器，控制器用于根据温度感受器反馈的检测结果控制电源22向雾化部12的电力供应，从而调节雾化部12的温度。
在一些实施例中，上述电子雾化器还包括吸嘴和气流通道。可选地，吸嘴位于壳体21上，用于抽吸气溶胶。壳体21上开设有供气体进入壳体21内部的进气孔211。在抽吸时，气体(例如空气)从进气孔211进入后带动雾化部12形成的气溶胶从吸嘴流出。当然，此时气溶胶生成品10就不必设置嘴件13。进一步地，电子雾化器还包括靠近吸嘴用于冷却气溶胶的冷却件。同理，此时气溶胶生成品10也可以不包括冷却元件。
上述电子雾化器与上述气溶胶生成品10适配，其电能的利用效率高。
此外，本申请还提供了一种雾化系统，包括上述气溶胶生成品10和与该气溶胶生成品10适配的上述电子雾化器，在气溶胶生成品10位于电子雾化器的容纳腔中时，气溶胶生成品10的雾化部12能与电源22电连接而雾化形成气溶胶。
