高粘度气溶胶生成基质的工作特性为，粘度随温度的升高而降低，如常温下，其粘度高达106cP(厘泊)，而当温度增加到70℃左右时，其粘度会降低到1000cP以下。相关技术中，当气溶胶产生基质的粘度较大时，气溶胶产生基质的流动性较差，从而导致导液组件20导液受阻，而吸液不畅会导致干烧，影响电子雾化装置的使用寿命以及用户的使用体验。
而本申请实施例提供的导液组件包括层叠设置的导热层21和隔离层22，隔离层22与电子雾化装置的发热件30接触，隔离层22用于隔离导热层21与发热件30，导热层21可以将电子雾化装置的气溶胶产生基质导向隔离层22，也就是说，电子雾化装置的部分气溶胶产生基质可以依次经导热层21和隔离层22导向发热件30，发热件30可以对气溶胶产生基质进行加热雾化并产生气溶胶。另外，通过设置导热层21，隔离层22可以将发热件30产生的部分热量传递至导热层21，导热层21可以将热量更快地传导至附近的气溶胶产生基质，导热层21附近的气溶胶产生基质受热升温后粘度降低，从而提高了导热层21附近的气溶胶产生基质的流动性，如此，一方面，有利于换气气泡的排除，在改善换气的同时，可以防止换气通道被堵塞；另一方面，导热层21附近的气溶胶产生基质的流动性的提高，有利于气溶胶产生基质经导液组件20导向发热件30，从而提高了导液组件20的导液效果。
需要说明的是，导热层21的具体材质不做限制，示例性地，一实施例中，导热层21为金属网层，也就是说，导热层21采用金属材料制成。如此，便于在制造过程中控制导热层21的尺寸以及形成网状结构，金属材料在加工过程中能够控制较好的尺寸精度和误差，使得加工精度更高，例如可以做的很薄。同时，金属材质的导热性能较好，即金属网层能够快速受热，从而可以快速地将热量传递给导热层21附近的气溶胶产生基质。另外，金属网层的多孔性能也能储存一部分粘度降低的气溶胶产生基质，从而源源不断地快速供给降低粘度的气溶胶产生基质到隔离层22，以使气溶胶产 生基质在隔离层22被加热雾化。
示例性地，导热层21为铜合金，该金属网层的材质可以根据气溶胶产生基质的特性选用不同的导热性能的金属或者合金，例如采用不锈钢、镍、铝、黄铜、紫铜等金属单质或者合金等制成，即采用上述材质编织成金属网层。
当然，导热层21也可以采用导热系数较好的非金属材质制成。
一实施例中，隔离层22为棉层，棉层的具体材质不做限制，示例性地，棉层的材质可以是天然有机棉，也可以是有机合成的高分子多孔泡沫棉。棉层为棉纤维材质，可以稳定储存部分气溶胶产生基质、并快速地将导热层21一侧的气溶胶产生基质导向发热件30，发热件30在通电状态下加热棉层上的气溶胶产生基质以形成气溶胶。另外，当导热层21为金属网层时，隔离层22通过采用棉层还可以隔绝金属网层与发热件30，以避免发热件30与导液组件20形成电连接，从而提高了雾化器1000的安全性能。
一实施例中，导热层21的孔隙率为0.45～0.99。当导热层21的孔隙率低于0.45时，会影响供液量，降低烟雾量；而当导热层21的孔隙率高于0.99时，会影响导热层21的结构强度。
一实施例中，导热层21的渗透率为1×10-11m2～1×10-9m2。渗透率是指在一定压差下，允许流体通过的能力，是表征导热层21传导液体能力的参数。当导热层21的渗透率低于1×10-11m2时，会影响供液量，降低烟雾量；而当导热层21的渗透率高于1×10-9m2时，则有可能会导致漏液。
一实施例中，隔离层22的孔隙率为0.45～0.99。当隔离层22的孔隙率低于0.45时，会影响供液量，降低烟雾量；而当隔离层22的孔隙率高于0.99时，会影响隔离层22的结构强度。
一实施例中，隔离层22的渗透率为1×10-11m2～1×10-9m2。渗透率是指在一定压差下，允许流体通过的能力，是表征隔离层22传导液体能力的参数。当隔离层22的渗透率低于1×10-11m2时，会影响供液量，降低烟雾量； 而当隔离层22的渗透率高于1×10-9m2时，则有可能会导致漏液。
一实施例中，请参阅图1至图3，发热组件100包括支撑件10、导液件以及发热件30，也就是说，储液腔1000a内的气溶胶产生基质可以经发热组件100的本体11的至少一端进入导液通道10a，导热层21套设于支撑件10的外周，隔离层22套设于导热层21的外周，导液组件20覆盖在导液孔10b的外侧，导液通道10a内的气溶胶产生基质可以经导液孔10b导向导液组件20，发热件30设置在隔离层22上，用于对隔离层22上的气溶胶产生基质进行加热雾化以产生气溶胶供使用者吸食。
示例性地，请参阅图1至图6，支撑件10为两端贯穿的中空管，中空管的管腔构成导液通道10a，导液孔10b沿中空管的径向贯穿中空管的侧壁。导热层21缠绕设置在中空管的侧壁，隔离层22缠绕设置在导热层21上以形成复合导液层，发热件30缠绕设置在隔离层22上。
需要说明的是，导液孔10b的具体形状在此不做限制，包括但不限于为圆形孔、椭圆形孔、长条孔、方孔等。
示例性地，请参阅图3至图6，导液孔10b包括沿本体11轴向分布的至少两排长条孔。如此，多排长条孔不仅便于导液通道10a中的气溶胶产生基质更大量地经长条孔导向导液组件20中，通过提高支撑件10的供液面积，以提高导液组件20的导液能力和发热组件100的雾化效率，还能够避免任意一个长条孔堵塞引起无法将导液通道10a中的气溶胶产生基质导向导液组件20的情况。示例性的，图3至图6所示的支撑件10沿本体11轴向分布的长条孔的排数为2排，即可以保障长条孔具有足够的长度，还可以保证支撑件10的供液面积。若沿本体11轴向分布的长条孔的排数为3排或更多，则可能会导致长条孔过短，从而导致降低了支撑件10的供液面积，若只有1排，此时若导液孔10b过短则导液面积不够，若导液孔10b太长则强度不够。
需要说明的是，本申请实施例中，至少两排是指数量包括两排以及两 排以上。
需要说明的是，长条孔可以是长方形孔，本申请实施例中的长条孔的两端设置圆弧平滑过渡，如此，在提高了本体11的强度的同时，还可以使得本体11更加美观。一具体实施例中，请参阅图4，长条孔的两端的圆弧的直径等于长条孔的宽度。
请参阅图1和图2，发热件30设置在导液组件20的隔离层22上，用于对气溶胶产生基质进行加热雾化以产生气溶胶供使用者吸食。发热件30包括但不限于为发热丝、发热网、发热带，其中，发热丝例如为圆形发热丝，当然还可以是其他形状的发热丝。本申请实施例中，以发热件30为呈螺旋状绕设在隔离层22外周的发热丝为例进行描述。
需要说明的是，导液通道10a的具体形状在此不做限制，导液通道10a的横截面形状包括但不限于为圆形、椭圆形、或倒圆角的多边形，例如倒圆角的三角形等，示例性地，一实施例中，请参阅图1、图2和图5，导液通道10a的横截面形状为圆形，有利于气溶胶产生基质在导液通道10a中流动地流畅性。其中，导液通道10a的横截面形状指沿垂直于本体11的轴向的平面所截得的导液通道10a的截面形状。
需要说明的是，支撑件10的导液孔10b一般是由激光加工而成的。相较于长条孔，在圆周上加工数百微米的圆孔阵列，加工所需激光行程长，耗时久，从而导致加工效率低，加工成本上升。
而本申请实施例提供的发热组件包括支撑件10、导液组件20以及发热件30，其中，支撑件10包括本体11、导液通道10a和导液孔10b，导液通道10a沿本体11的轴向贯穿本体11的两端，导液孔10b沿本体11的径向贯穿导液通道10a的侧壁。可以理解的是，支撑件10的供液面积为本体11上所有导液孔10b开口的总面积，通过将导液孔10b设置为包括沿本体11轴向分布的至少两排长条孔，一方面增加了支撑件10的供液面积，支撑件10上可供雾化的气溶胶产生基质更多，提高了发热组件100的供液能力和 雾化效率，在保持温度不变的情况下，发热组件100单位时间的气溶胶产生量更大；另一方面，沿本体11轴向分布的至少两排长条孔，可以在保障支撑件10具有一定供液面积的前提下，相邻两排长条孔之间可以通过导液通道10a的侧壁连接，提高了支撑件10的结构强度。另外，通过将导液孔10b设置为包括沿本体11轴向分布的至少两排长条孔，相比于圆形孔等其他孔，在具有相同供液面积的情况下，长条孔的加工所需的切割周长短、易于加工，减少了加工工序，从而提高了加工效率，降低了加工成本。
一实施例中，请参阅图4和图6，长条孔沿本体11的轴向延伸，也就是说，长条孔的长度方向沿本体11的轴向设置，即长条孔的长度方向与本体11的轴向方向相同。如此可以在保障支撑件10具有一定供液面积的前提下，相邻两排长条孔之间可以通过导液通道10a的侧壁连接，提高了支撑件10的结构强度。另外，还提高了加工效率。
一实施例中，长条孔沿本体11的周向延伸，也就是说，长条孔的长度方向沿本体11的周向设置，即长条孔的长度方向与本体11的轴向近似垂直。如此可以在保障支撑件10具有一定供液面积的前提下，相邻两排长条孔之间可以通过导液通道10a的侧壁连接，提高了支撑件10的结构强度，且还可以沿本体11的轴向设置更多的长条孔，进一步地提高了支撑件10的供液面积。另外，还提高了加工效率。
另一些实施例中，长条孔的延伸方向与本体11的轴向倾斜设置，即长条孔的长度方向与本体11的轴向呈一定角度设置。
一实施例中，支撑件10为金属件，也就是说，支撑件10采用金属材料制成。如此，便于在制造过程中控制支撑件10的尺寸，金属材料在加工过程中能够控制较好的尺寸精度和误差，使得加工精度更高，例如可以做的很薄。同时，金属材质本身具有一定的导热性能，从而可以提高发热组件100的雾化效率。即采用金属材料制成的支撑件10同时具有支撑、导液和导热的功能。而通过提高支撑件10的导热性能，可以使得导热层21将 热量更快地传导至支撑件10上，支撑件10进而将热量更快地传导至附近、导液通道10a或者储液腔1000a内的气溶胶产生基质，气溶胶产生基质受热升温后粘度降低，从而提高了支撑件10附近、导液通道10a或者储液腔1000a内的气溶胶产生基质的流动性，在改善换气的同时，有利于气溶胶产生基质经导液组件20导向发热件30，从而提高了导液组件20的导液效果。
示例性地，支撑件10例如采用不锈钢、铝合金、黄铜合金等制成。本申请实施例中，支撑件10例如采用304不锈钢制成。
当然，支撑件10还可以采用玻璃制成，玻璃具体为硼硅玻璃、石英玻璃或光敏铝硅酸锂玻璃中的任意一种。另一些实施方式中，支撑件10的材料还可以为陶瓷、金属、硬质塑料、高分子等无机非材料等具有一定机械强度的部件。
支撑件10通过采用金属材料制成，在保障强度、安全性的情况下，使用金属材料，可以将支撑件10适当地减薄，即可以适当的减薄本体11的壁厚，降低了支撑件10的质量，从而降低了支撑件10的热容消耗，提高了发热组件100的加热效率；如此，在相同的外径情况下，可以使得本体11的内径更大，导液通道10a中的宏观流动阻力更小；另外，通过降低本体11的壁厚，缩短了气溶胶产生基质从导液通道10a流向导液组件20的路径，进一步地降低了气溶胶产生基质的流动阻力，进而提高了发热组件100的供液能力和雾化效果。
一实施例中，导液孔10b包括沿本体11的周向分布的至少两列长条孔。示例性的，请参阅图6，沿本体11周向分布的长条孔的列数为4列。如此，多列长条孔不仅便于导液通道10a中的气溶胶产生基质更大量地经长条孔导向导液组件20中，通过提高支撑件10的供液面积，以提高发热组件100的供液能力和雾化效率，还能够避免任意一列长条孔堵塞引起无法将导液通道10a中的气溶胶产生基质导向导液组件20的情况。
需要说明的是，本申请实施例中，至少两列是指数量包括两列以及两 列以上。
一实施例中，相邻两列长条孔交错设置。如此，可以提高支撑件10的结构强度。
一实施例中，请参阅图6，相邻两列长条孔并排设置。如此，在提高加工效率的同时，还提高了支撑件10的美观性。
导液孔10b对称分布在本体11上，导液孔10b呈对称结构可以降低激光加工的制费。另外，导液孔10b对称分布在本体11上，可以使得导液通道10a内的气溶胶产生基质经导液孔10b均匀地导向导液组件20，进而提高雾化效果。示例性地，一实施例中，导液孔10b沿本体11的轴向对称分布。另一些实施例中，导液孔10b沿本体11的周向对称分布。又一些实施例中，导液孔10b沿本体11的中心轴对称分布。
一实施例中，请参阅图1至图3，本体11沿轴向的长度大于导液组件20沿轴向的长度。也就是说，本体11沿轴向伸出导液组件20的部分可以设置在储液腔1000a内，如此，可以使得导热层21将热量更快地传导至支撑件10上，支撑件10可以通过伸入至储液腔1000a内的部分将热量更快地传导至储液腔1000a内的气溶胶产生基质，气溶胶产生基质受热升温后粘度降低，从而提高了储液腔1000a内位于支撑件10附近的气溶胶产生基质的流动性，在改善换气的同时，有利于气溶胶产生基质经导液组件20导向发热件30，从而提高了发热组件100的导液效果和雾化效果。
一实施例中，请参阅图1和图2，导热层21沿轴向的长度大于隔离层22沿轴向的长度，即导热层21沿支撑件10轴向的长度大于隔离层22沿支撑件10轴向的长度，如此，可以增加导热层21与支撑件10以及气溶胶产生基质的接触面积，即可以进一步地把更多地热量更快地传导至支撑件10上，进而可以使得支撑件10将热量更快地传导至支撑件10附近的气溶胶产生基质，以降低导热层21附近气溶胶产生基质的流动性，进而改善导液组件20的导液效果以及换气。
一实施例中，请参阅图5，本体11的内径D为0.3mm-3mm，也就是说，导液通道10a的直径为0.3mm-3mm。本体11的内径若过小，即导液通道10a的直径过小，则会影响气溶胶产生基质在导液通道10a内的流动，降低了发热组件100的供液能力，进而降低雾化器1000的雾化效率。若本体11的内径过大，则使得发热组件100的体积较大，一方面会占用雾化器1000的内部空间，另一方面，还会导致雾化器1000的体积较大，不利于产品的美观。通过将本体11的内径限定在0.3mm-3mm之间，能够在保障发热组件100供液能力的同时，提高雾化器1000的美观性。可以理解的是，本体11的内径根据实际需要进行选择，例如根据具体烟弹的大小，确定本体11的内径。
一实施例中，请参阅图4，本体11的轴向长度L1为3mm-30mm。可以理解的是，本体11的轴向长度越长，对应的导液组件20也将越长，发热件30覆盖的范围也将越大，导液孔10b的供液面积也将越大。如此，本体11的轴向长度若过小，则会降低了发热组件100的供液能力以及雾化效率。若本体11的轴向长度过大，则使得发热组件100的体积较大，一方面会占用雾化器1000的内部空间，另一方面，还会导致雾化器1000的体积较大，不利于产品的美观。通过将本体11的轴向长度限定在3mm-30mm之间，能够在保障发热组件100供液能力以及雾化效率的同时，提高雾化器1000的美观性。可以理解的是，本体11的轴向长度根据实际需要进行选择，例如根据具体烟弹的大小，确定本体11的轴向长度。
一实施例中，请参阅图5，本体11的壁厚L2为0.05mm-0.2mm。可以理解的是，在保障强度、安全性的情况下，可以尽可能地减薄本体11的壁厚，如此，降低了本体11的质量，从而降低了本体11的热容消耗，提高了发热组件100的加热效率；另外，在相同的外径情况下，可以使得本体11的内径更大，导液通道10a中的宏观流动阻力更小；另外，通过降低本体11的壁厚，缩短了气溶胶产生基质从导液通道10a流向导液组件20的 路径，进一步地降低了气溶胶产生基质的流动阻力，进而提高了发热组件100的供液能力和雾化效果。
一实施例中，请参阅图4，长条孔的宽度L3为0.3mm-0.8mm。能够理解的是，长条孔的宽度若过小，则不利于气溶胶产生基质的流通，即降低了发热组件100的供液能力，降低了雾化器1000的雾化效率。长条孔的宽度若过大，则降低支撑件10的结构强度，进而降低发热组件100的使用寿命，同时，长条孔的宽度若过大，可能会导致漏液。通过将长条孔的宽度限定在0.3mm-0.8mm之间，能够在保障雾化器1000的雾化效率的同时，延长发热组件100的使用寿命。
一实施例中，请继续参阅图4，长条孔的长度L4为1mm-3mm。可以理解的是，长条孔的长度若过小，则不利于气溶胶产生基质的流通，即降低了发热组件100的供液能力，降低了雾化器1000的雾化效率。长条孔的长度若过大，则降低支撑件10的结构强度，进而降低发热组件100的使用寿命，同时，长条孔的宽度若过大，可能会导致漏液。通过将长条孔的长度限定在1mm-3mm之间，能够在保障雾化器1000的雾化效率的同时，延长发热组件100的使用寿命。
一实施例中，请继续参阅图4，沿本体11轴向分布的相邻两排长条孔之间的间距L5为0.6mm-1.2mm。需要说明的是，沿本体11轴向分布的相邻两排长条孔之间的间距类似于相邻两排长条孔之间的微型肋，即相邻两排长条孔之间通过微型肋连接，用于保障支撑件10的强度。若相邻两排长条孔之间的间距过小，则会降低支撑件10的结构强度，进而降低发热组件100的使用寿命。若相邻两排长条孔之间的间距过大，则会降低支撑件10的供液面积，进而降低发热组件100的供液能力和雾化效率。通过将沿本体11轴向分布的相邻两排长条孔之间的间距限定在0.6mm-1.2mm之间，能够在保障雾化器1000的供液能力和雾化效率的同时，延长发热组件100的使用寿命。
一实施例中，请继续参阅图4，最靠近本体11端部的长条孔与本体11的端部之间的间距L6为1mm-3mm。需要说明的是，最靠近本体11端部的长条孔即为本体11两端的边缘孔。若边缘孔与本体11的端部之间的间距过大，则会降低支撑件10的供液面积，进而降低发热组件100的供液能力和雾化效率。若边缘孔与本体11的端部之间的间距过小，则降低支撑件10的结构强度，进而降低发热组件100的使用寿命。通过将最靠近本体11端部的长条孔与本体11的端部之间的间距限定在1mm-3mm之间，能够在保障雾化器1000的雾化效率的同时，延长发热组件100的使用寿命。
一具体实施例中，本体11的轴向长度L1为8mm，长条孔的长度L4为1.8mm，长条孔的宽度L3为0.5mm，沿本体11轴向分布的相邻两排长条孔之间的间距L5为0.8mm。
另一些实施例中，导液孔10b的当量孔径为0.01mm-3mm。防止因孔径过小而影响气溶胶产生基质的流通，即降低了发热组件100的供液能力，因孔径过大而导致降低支撑件10的结构强度，进而降低发热组件100的使用寿命，同时，若孔径过大，可能会导致漏液。
一实施例中，请参阅图1和图2，导热层21沿支撑件10轴向的长度大于隔离层22沿轴向的长度，如此，可以增加导热层21与支撑件10以及气溶胶产生基质的接触面积，即可以进一步地把更多地热量传递给气溶胶产生基质，以降低导热层21附近气溶胶产生基质的流动性，进而改善导液组件20的导液效果以及换气。
