参照图1至图12，本公开实施例提供了一种电子烟雾化芯100，应用于电子烟，电子烟雾化芯100包括：
多孔体1和发热体3，多孔体1包括吸液端和雾化端，雾化端具有远离吸液端的端面，电子烟内部的烟油会通过吸液端渗向雾化端。发热体3设置于端面，也就是发热体3设置于多孔体1远离吸液端的一端，以使雾化端上形成雾化面。
雾化面包括第一雾化区，第一雾化区位于端面，第一雾化区为通过发热体3加热能够达到预定雾化温度范围的区域，也就是流至第一雾化区的烟油可以被有效雾化，并且第一雾化区的面积与端面的面积比值为0.05-0.90。电子烟的烟油在流至端面时，发热体3在发热的情况下可以将第一雾化区的烟油进行雾化，以提供给用户可供吸食的烟雾。
具体地，发热体3设置于多孔体1远离吸液端的端面，端面的面积过大时，发热体3在端面上占据的面积过小，也就使得第一雾化区的面积与端面的面积比值过小，端面的面积无法被有效用来产生烟油的雾化。较大的端面面积一方面增加了对电子烟空间的占用，另一方面降低了电子烟雾化芯100的雾化效率。端面的面积过小时，发热体3虽然可以在端面上占据的面积较大，也就使得第一雾化区的面积与端面的面积比值较大，但端面上还需要设置接线盘等实现发热体电连接的组件，无法实现端面全部的雾化效果。所以，本公开将第一雾化区的面积与端面的面积比值控制在0.05-0.90的范围内，可以在保证发热体3及其电连接组件设置的情况下，提高电子烟雾化芯100的雾化效率。
具体地，发热体3可以沿多孔体1的周向弯折形成至少一个凸起段和/或至少一个凹陷段，端面的至少一段边缘与发热体3的轮廓相匹配，比如端面的至少一段边缘与发热体3的轮廓边缘等间距设置，或者，端面的整体边缘与发热体3的整体轮廓相匹配。
具体地，端面可以包围发热体3的有效发热区，使得发热体3在发热时可以在端面和多孔体1侧面均形成雾化面，雾化面也就是发热体3发热时温度达到雾化温度的区域，比如温度达到150℃或者达到180℃以上的区域。由于发热体3设置于端面，发热体3在加热时，可以直接对端面进行加热，也就是形成第一雾化区。第一雾化区上的烟油在加热后可以进行雾化，提高了发热体3的发热效率和电子烟雾化芯100的雾化效果。
本公开实施例提供的电子烟雾化芯100包括多孔体1和发热体3，多孔体1的雾化端具有远离吸液端的端面。发热体3设置于端面，以使雾化端上形成雾化面。雾化面包括第一雾化区，第一雾化区位于端面，并且第一雾化区的面积与端面的面积比值为0.05-0.90。第一雾化区为通过发热体3加热能够达到预定雾化温度范围的区域，也就是流至第一雾化区的烟油可以被有效雾化，在保证发热体3灵活设置的情况下，提高了电子烟雾化芯100的雾化效率。
可选地，第一雾化区的面积与端面的面积比值为0.25-0.75，优选0.40-0.60。
具体地，第一雾化区为通过发热体3加热能够达到预定雾化温度范围的区域。由于第一雾化区位于端面，为了达到对端面面积的充分利用，可以通过弯折状的发热体3形成至少一个凸起段和/或至少一个凹陷段，凸起段可以对端面的边缘甚至多孔体1的侧面进行加热雾化，而凹陷段内可以对端面的中部进行雾化。使得第一雾化区的面积与端面面积的比值增大。比如端面的面积为20mm 2时，通过发热体3的加热，预定雾化温度为180℃以上的第一雾化区面积可以达到4.8mm 2以上,预定雾化温度为200℃以上的第一雾化区面积可以达到3mm 2以上。
可选地，预定雾化温度范围为150-300℃，优选180-240℃。
具体地，电子烟中的烟油会通过多孔体1的吸液端渗向端面，发热体 3在发热的情况下，可以使第一雾化区的温度达到预定雾化温度，进而使第一雾化区的上的烟油进行雾化。由于电子烟的烟油的主要成份为丙二醇、植物甘油、纯水和香精，在预定雾化温度范围为150-300℃的情况下，可以保证第一雾化区的上的烟油能够得到部分或者全部雾化，保证电子烟雾化芯100的雾化效率。
可选地，雾化面包括第二雾化区，第二雾化区为通过发热体3加热能够达到预定雾化温度范围的区域，第二雾化区为雾化端的至少部分侧面，侧面与端面相邻。
具体地，发热体3的延伸轨迹在靠近端面的至少一段边缘时，发热体3加热散发的热量可以传递至多孔体1的至少部分侧面，使得多孔体1的至少部分侧面的温度达到预定雾化温度范围，也就是在多孔体1的至少部分侧面形成第二雾化区。第二雾化区与第一雾化区的配合，增加了雾化面的面积，提高了电子烟雾化芯100的雾化量，进而保证了电子烟雾化芯100的雾化效果。
可选地，第二雾化区的面积与侧面的面积比值为0.05-0.90，优选0.25-0.75，进一步优选0.40-0.60。
具体地，第二雾化区为通过发热体3加热能够达到预定雾化温度范围的区域。由于第二雾化区位于多孔体1的侧面，为了达到对侧面面积的充分利用，需要不断提高发热体3的加热温度。比如在第二雾化区的面积与侧面的面积比值过大时，也就需要发热体3的加热温度过高，这样一方面会消耗过多的能量，产生较大的能量损耗，另一方面过高的发热体3的温度会使得烟油碳化，在发热体3的表面形成黑色的碳层，降低了电子烟雾化芯100的雾化效率和使用寿命。而在第二雾化区的面积与侧面的面积比值过小时，虽然不需要对发热体3的加热温度有较高的要求，但第二雾化区面积的减小同样降低了电子烟雾化芯100的雾化效率。
可选地，电子烟雾化芯100还包括接线盘4，接线盘4连接于发热体3的两端；
接线盘4的面积与端面面积的比值为0.02-0.25，优选0.15-0.2。
在一些实施方式中，参见图1至图12，接线盘4设置于端面上，接线 盘4上设置有电极，电极用于与外部电源电连接。接线盘4的端部可以设置成圆弧形，使得接线盘4的面积与端面面积的比值控制在0.02-0.25的范围内，避免接线盘4的面积对端面面积的过多占用，而且减少了接线盘4对发热体3热量的吸收，提高了发热体3的雾化效率。
具体地，接线盘4上的电极可以包括正电极和负电极。发热体3用于电子烟时，通过电子烟内的电源给正电极和负电极施加电压，便可以给发热体3通电，发热体3在通电的情况下可以将电能转化为热能，发热体3发热时便可以将电子烟雾化芯100雾化端的烟油雾化，保证电子烟的雾化效果。
可选地，参见图1至图4，发热体3呈方波状设置于端面。
具体地，参见图1，方波状发热体3可以包括一个第一弯折段和一个第二弯折段，第一弯折段与第二弯折段的弯折方向相反。发热体3的两端分别为第一连接段和第二连接段，发热体3还包括第一加热段、第二加热段和第三加热段，第一加热段连接在第一连接段和第一弯折段之间，第二加热段分别与第一弯折段和第二弯折段连接，第三加热段连接在第二弯折段和第二连接段之间。第一弯折段和第二弯折段可以分别形成一个凸起段，第一加热段、第二加热段和第三加热段可以分别形成一个凹陷段。第一连接段和第二连接段分别延伸至第一雾化区的两端，第一加热段、第二加热段、第三加热段、第一弯折段和第二弯折段可以给发热体3提供了主要的热源，对雾化面进行均衡加热。
可选地，端面呈椭圆形，发热体3沿端面的长度方向设置，端面的一端边缘与其相对应发热体3的端部之间形成第一间距，端面的侧边边缘与其相对应发热体3的侧边之间形成第二间距；
第一间距的范围为0.05-4.0mm，第二间距的范围为0.05-4.0mm。
具体地，电子烟雾化芯100通过发热体3的加热，使得多孔体的雾化端上形成雾化面。为了保证发热体3在较低的设置长度情况下，提高发热体3的加热效率，可以将发热体3沿多孔体1的周向弯折形成至少一个凸起段和/或至少一个凹陷段，使得发热体3的整体轮廓呈椭圆形。多孔体1的端面与发热体3的整体轮廓相匹配时，可以将端面设置为椭圆形。发热 体3在沿端面的长度方向设置时，端面的一端边缘与其相对应发热体3的端部之间形成第一间距，端面的侧边边缘与其相对应发热体3的侧边之间形成第二间距。将第一间距的范围和第二间距的范围均控制在0.05-4.0mm的范围内时，可以通过发热体3的加热，使得第一间距中的至少部分和第二间距中的至少部分达到预定雾化温度范围，以达到简化发热体3的结构设置和提高发热体3加热效率的双重目的。
可选地，第一间距的范围为0.05-2.0mm，和/或第二间距的范围为0.05-2.0mm。
具体地，第一间距和第二间距的范围较大时，一方面占据了较大的端面面积，另一方面在第一间距和第二间距的空间未被有效利用时，降低了端面的雾化利用率。而通过对端面进行切割或缩小成型模具尺寸等手段时，使得第一间距和第二间距的范围减小至0.05-2.0mm，以提高端面与发热体3的匹配度，提高第一雾化区的面积与端面的面积比值。
在一种具体地实施例中，参见图1至图3，图1中端面的左端边缘与发热体3的左端部之间形成第一间距，端面的右端边缘与发热体3的右端部之间也形成第一间距；端面的上侧边边缘与发热体3的上侧边之间形成第二间距，端面的下侧边边缘与发热体3的下侧边之间形成第二间距。由于图1中的第一间距较大，无法在发热体3加热时被充分利用，可以将端面的左右两端进行切割，如图1至图2的变化，以减小第一间距的尺寸，提高第一间距范围内端面的雾化利用率；另外，由于图1中的第二间距较大，无法在发热体3加热时被充分利用，可以将端面的上下两侧进行切割，如图1至图3的变化，以减小第二间距的尺寸，提高第二间距范围内端面的雾化利用率。
可选地，端面边缘的至少一段呈台阶状。
具体地，由于第一间距和第二间距的尺寸较大，为了同时提高第一间距和第二间距范围内端面的雾化利用率，可以对端面上第一间距和第二间距连接的位置进行切割，如图1至图3的变化。在减小端面左上角和右下角尺寸时，可以显著提高端面的雾化利用率。
可选地，参见图5至图8，发热体3呈波浪形设置于端面。
具体地，发热体3呈波浪形时，发热体3可以弯折形成多个凸起段和多个凹陷段，波浪形发热体3可以靠近端面的一侧边缘，如图5所示；发热体3的波浪形设置可以提高发热体3的加热效率，达到对雾化面的均衡加热，提高第一雾化区的面积与端面的面积比值。
可选地，端面呈椭圆形，发热体3沿端面的长度方向设置。
具体地，参见图5，端面设置为椭圆形并且发热体3沿端面的长度方向设置时，端面的左端边缘与发热体3的左端部之间形成第一间距，端面的右端边缘与发热体3的右端部之间也形成第一间距；端面的下侧边边缘与发热体3的下侧边之间形成第二间距。由于图5中的第一间距较大，无法在发热体3加热时被充分利用，可以将端面的左右两端进行切割，如图5至图6的变化，以减小第一间距的尺寸，提高第一间距范围内端面的雾化利用率；另外，由于图5中的第二间距较大，无法在发热体3加热时被充分利用，可以将端面的上下两侧进行切割，如图5至图7的变化，以减小第二间距的尺寸，提高第二间距范围内端面的雾化利用率。
可选地，参见图8，端面包括相互垂直的第一端面和第二端面，第一端面的长度大于第二端面的长度，发热体3沿第一端面的长度方向设置。
具体地，第一端面和第二端面的设置使得端面呈十字形，由于第一端面的长度大于第二端面的长度，发热体3沿第一端面的长度方向设置时，可以在保证发热体3发热效率的基础上，提高第一雾化区的面积与端面的面积比值。从图8与图5的对比来看，由于第一间距和第二间距的尺寸较大，为了同时提高第一间距和第二间距范围内端面的雾化利用率，可以对端面上第一间距和第二间距连接的位置进行切割，具体为对端面的四角进行切割，以提高端面的雾化利用率。
可选地，参见图9至图12，发热体3呈之字形设置于端面。
具体地，参见图9，之字形发热体3包括一个第一弯折段和一个第二弯折段，第一弯折段与第二弯折段的弯折方向相反，发热体3的两端分别为第一连接段和第二连接段。发热体3还包括第一加热段，第一加热段连接在第一弯折段和一个第二弯折段之间。第一弯折段和第二弯折段分别形成一个凸起段，第一加热段形成一个凹陷段。第一连接段和第二连接段分 别延伸至第一雾化区的两端，第一加热段、第一弯折段和第二弯折段给发热体3提供了主要的热源，可以对雾化面进行均衡加热。
可选地，端面呈椭圆形，发热体3沿端面的长度方向设置。
具体地，参见图9，端面设置为椭圆形并且发热体3沿端面的长度方向设置时，端面的左端边缘与发热体3的左端部之间形成第一间距，端面的右端边缘与发热体3的右端部之间也形成第一间距；端面的上侧边边缘与发热体3的上侧边之间形成第二间距，端面的下侧边边缘与发热体3的下侧边之间形成第二间距。由于图9中的第一间距较大，无法在发热体3加热时被充分利用，可以将端面的左右两端进行切割，如图9至图10的变化，以减小第一间距的尺寸，提高第一间距范围内端面的雾化利用率；另外，由于图9中的第二间距较大，无法在发热体3加热时被充分利用，可以将端面的上下两侧进行切割，如图9至图11的变化，以减小第二间距的尺寸，提高第二间距范围内端面的雾化利用率。
可选地，参见图12，端面包括相互垂直的第一端面和第二端面，第一端面的长度大于第二端面的长度，发热体3沿第一端面的长度方向设置。
具体地，第一端面和第二端面的设置使得端面呈十字形，由于第一端面的长度大于第二端面的长度，发热体3沿第一端面的长度方向设置时，可以在保证发热体3发热效率的基础上，提高第一雾化区的面积与端面的面积比值。从图12与图9的对比来看，由于第一间距和第二间距的尺寸较大，为了同时提高第一间距和第二间距范围内端面的雾化利用率，可以对端面上第一间距和第二间距连接的位置进行切割，具体为对端面的四角进行切割，以提高端面的雾化利用率。
本公开还提供了一种电子烟，电子烟包括本公开的电子烟雾化芯100。
具体地，电子烟的电子烟雾化芯100包括多孔体1和发热体3，多孔体1的雾化端具有远离吸液端的端面。发热体3设置于端面，以使雾化端上形成雾化面。雾化面包括第一雾化区，第一雾化区位于端面，并且第一雾化区的面积与端面的面积比值为0.05-0.90。第一雾化区为通过发热体3加热能够达到预定雾化温度范围的区域，也就是流至第一雾化区的烟油可以被有效雾化，在保证发热体3灵活设置的情况下，提高了电子烟的雾化 效率。
可选地，参见图13和图14，电子烟还包括壳体101、设于壳体101内的储液腔102和第一密封元件108，第一密封元件108套设在多孔体1上，第一密封元件108至少覆盖多孔体1的部分外周面以及吸液端的边缘。

具体地，电子烟雾化组件工作时，由储油仓102流出的烟油经由导油孔1032导流至多孔体1的吸液端，并由多孔体1的毛细作用吸收至多孔体1在雾化端的发热体3，通过发热体3的加热雾化成雾气，此时用户在出气通道1011的抽吸作用下带动进气孔1051的空气进入雾化室106中，携带雾化室106的气溶胶导出至出气通道1011。由于烟油不断由多孔体1吸收补充至发热体3，储油仓102内形成负压，在负压的作用下，外部空气可通过雾化室106和电子烟雾化芯100后，进入导油孔1032和储油仓102，以形成气压平衡，保证烟油可以顺畅地导入多体1。
