请一并参阅图1至2，现对本发明实施例提供的雾化芯进行说明。本发明实施例提供的雾化芯用于雾化器，其可在气溶胶发生装置的电源装置的电驱动下发热，将雾化器的储液腔中的气溶胶形成基质加热雾化形成烟雾，以供用户吸食而达到模拟吸烟的效果。
请进一步结合参阅图1，本发明实施例提供的雾化芯包括多孔高分子吸液件1、发热件2和结合件3。多孔高分子吸液件1的孔隙率为30～90％，多孔高分子吸液件1的孔径为1～300μm，多孔高分子吸液件1可以通过毛细作用力将气溶胶形成基质快速地吸附并储存于多孔高分子吸液件1的空隙中。多孔高分子吸液件1包括由高分子材料制成的有机高分子基体，有机高分子基体含有-CH基团，在键合连接过程中，在有机高分子基体的表面引入-OH基团，并代替了-CH基团，使得结合件3与有机高分子基体建立键合连接，从而使有机高分子基体的表面与结合件3贴合。由于气溶胶形成基质中的有机物(例如如植物提取香精、尼古丁等)的表面张力等于0.1至5倍的有机高分子基体表面自由能，因此气溶胶形成基质中的有机物的表面张力与有机高分子基体表面自由能相近，气溶胶形成基质中的有机物会在有机高分子基体的表面迅速铺展开， 并快速渗入有机高分子基体的空隙中，多孔高分子吸液件1可起到吸附及传导气溶胶形成基质的作用。优选地，气溶胶形成基质中的有机物的表面张力等于0.2至2倍的有机高分子基体表面自由能。发热件2可在通电后产生热量，对气溶胶形成基质进行加热雾化。结合件3的一面紧密结合于有机高分子基体的表面上，发热件2形成于结合件3背离有机高分子基体的一面上，则可通过结合件3将发热件2结合并支撑于有机高分子基体的表面上。
请进一步结合参阅图2，结合件3上贯穿设置有若干第一通孔4，结合件3上的第一通孔4可供有机高分子基体中的气溶胶形成基质传输至发热件2，以使有机高分子基体向发热件2提供气溶胶形成基质。则在雾化芯使用时，通过气溶胶发生装置的电源装置向雾化芯供电，发热件2在通电后产生热量，加热传输至发热件2上的气溶胶形成基质，以将气溶胶形成基质雾化形成可供用户吸食的烟雾。
本发明实施例提供的雾化芯，与现有技术相比，通过采用包括有机高分子基体的多孔高分子吸液件1，通过结合件3将发热件2结合并支撑于有机高分子基体的表面上，并在结合件3上设置可供有机高分子基体中的气溶胶形成基质均匀稳定地传输至发热件的第一通孔4。则在使用时，由于气溶胶形成基质中的有机物的表面张力与有机高分子基体表面自由能相近，在有效提高气溶胶形成基质传输效率的同时，能够将气溶胶形成基质中的香精或尼古丁等有效成分充分地传输发热件2，以提高香气的还原度及烟雾的浓郁度。此外，采用包括有机高分子基体的多孔高分子吸液件1代替多孔陶瓷吸液件，可有效提高气溶胶形成基质传输效率，能够良好地避免由于气溶胶形成基质供应不足而产生的雾化芯干烧、积碳、失效现象。
本发明实施例提供的雾化芯，与现有技术相比，通过采用包括有机高分子基体的多孔高分子吸液件1，结合件3与有机高分子基体建立键合连接，从而使有机高分子基体的表面与结合件3贴合，通过结合件3将发热件2结合并支撑于有机高分子基体的表面上，并在结合件3上设置可供有机高分子基体中的 气溶胶形成基质均匀稳定地传输至发热件2的第一通孔4。则在运输、使用过程中，避免因振动、跌落等情况而发生结合件3与有机高分子基体分离的情况，保证发热件2的气溶胶形成基质供应充足，能够良好地避免气溶胶形成基质供应不足而产生的雾化芯干烧、积碳、失效。可以理解地，结合件3与有机高分子基体分离会导致结合件3传输至发热件2的气溶胶形成基质不足，发热件2的气溶胶形成基质供应不足会导致发热件2温度过高，从而产生有害物质，以及产生积碳现象而影响口感，且严重情况下造成雾化芯失效。
在其中一些实施方式中，有机高分子基体由有机高分子材料制成，有机高分子基体具有改性为亲油疏水或者亲水疏油特性的属性，使得有机高分子基体在有效提高气溶胶形成基质传输效率的同时，能够将气溶胶形成基质中的香精或尼古丁等有效成分充分地传输至发热件2，以提高香气的还原度及烟雾的浓郁度。有机高分子基体可以是但不限于多孔PDMS基体、多孔PMMA基体、多孔PI基体、多孔PC基体和多孔PET基体中的至少一种。其中，由于聚二甲基硅氧烷(PDMS)与气溶胶形成基质具有较好的浸润性，具备优良的改性的能力，安全无毒，化学稳定性比较高，在-60～300℃的使用环境中不会发生物理化学变化，优先选用聚二甲基硅氧烷(PDMS)制备得到有机高分子基体。
在其中一些实施方式中，多孔高分子吸液件1还包括由无机材料制成的骨架基体，有机高分子基体与骨架基体通过复合工艺组合而成有机-无机复合基体，有机高分子基体可以是但不限于多孔PDMS基体、多孔PMMA基体、多孔PI基体、多孔PC基体和多孔PET基体中的至少一种，骨架基体可以是但不限于氧化物基体、氮化物基体、碳化物基体、硼化物基体、硅化物基体和氟化物基体中的至少一种。具体地，作为一种可实施方案，有机-无机复合基体可以由多孔PDMS基体与硅藻土基体复合而成，或者有机-无机复合基体也可以由多孔PI基体与硅藻土基体复合而成。
在其中一些实施方式中，多孔高分子吸液件1为新型多孔基体，新型多孔基体可以是但不限于多孔MOFs基体和多孔气凝胶基体中的至少一种。其中， 由于金属有机骨架化合物(MOFs)是一类由金属离子和有机配体通过配位键络合而成的多孔材料，其中金属离子大多为过渡金属离子，如Zn2+、Cu2+、Ni2+、Pd2+、Ru2+、Co2+等，有机配体可以是但不限于含氮杂环有机配体、含羧基有机配体、含氮杂环与羧酸混合配体或两种羧酸混合配体中的至少一种，与传统的无机多孔材料相比，MOFs具备高孔隙和高比表面积，此外有机成分的存在使MOFs具有可裁剪性，MOFs结构的多样性使其功能也具有多样性。其中，多孔气凝胶基体可以是但不限于多孔氧化铝气凝胶基体。
在其中一些实施方式中，结合件3为结合于有机高分子基体表面上的结合层，结合层可以是但不限于硅层、玻璃层、不锈钢层中的至少一种。由于多孔高分子吸液件1包括有机高分子基体，采用上述硬度大、耐高温、易开孔加工的硅、玻璃、不锈钢材质制作结合件3，使得发热件2能够稳固地结合于柔性的有机高分子基体表面上。此外，请结合参阅图3，由于采用硅、玻璃、不锈钢等刚性材质制作的结合件3，结合件3具有致密平整或致密光滑的表面，在发热件2为发热层时，不仅有利于加工发热层，还使得发热层能够保持良好的连续性与厚度的均匀一致性，便于优化电阻的分布，使加热区域的温度场分布更均匀。并且结合件3隔断发热层2与多孔改性吸液件1的直接热量交换，克服传统雾化芯中吸液件与加热件直接热量交换而产生多孔高分子吸液件1被加热碳化现象。
在其中一些实施方式中，发热件2可以是但不限于发热层、发热膜、发热丝、发热网中的任意一种。
请进一步结合参阅图1，在其中一些实施例中，结合件3上设置有多个第一通孔4，结合件3为层叠设置于有机高分子基体上的结合层，发热件2为层叠设置于结合层上的发热层，发热层上对应各第一通孔4的位置分别设有第二通孔5，各第一通孔4与相应第二通孔5贯通，以使贯通的第一通孔4与第二通孔5形成用于传输和/或存储气溶胶形成基质的孔道6。该实施例中，结合件3上的第一通孔4与发热层上的第二通孔5贯通，形成用于传输和/或存储气溶 胶形成基质的孔道6，发热层发热时可直接加热流经孔道6中的气溶胶形成基质，使气溶胶形成基质均匀受热，克服传统雾化芯对气溶胶形成基质加热不均匀且雾化芯容易发生干烧积碳的问题。请进一步结合参阅图2，在其中一些实施例中，为了保证向发热层2传输气溶胶形成基质的均匀性及较高的导液速率，在结合件3上设置有多个第一通孔4。可以理解地，在其中一些实施例中，多个第一通孔4呈矩阵的形式布置于结合件3上，相邻两个第一通孔4之间的间距相等。在其他一些实施例中，多个第一通孔4的分布可根据加热区域的温度场分布进行调整，在温度高的区域增加第一通孔4的数量，在温度低的区域减少第一通孔4的数量，使加热区域的温度场分布与气溶胶形成基质的导液速率相匹配，不仅能够良好地避免由于气溶胶形成基质供应不足而产生的雾化芯干烧积碳现象，还能够良好地避免由于气溶胶形成基质供应过多而产生的雾化芯雾化效率降低现象。
可以理解地，在其中一些实施例中，第一通孔4的形状可以是圆形、方形、三角形、菱形，但不限于圆形、方形、三角形、菱形。例如第一通孔4的形状还可以是椭圆形、梯形、弯月形、梅花形等其他形状。在其中一些实施例中，第一通孔4的孔径为1～200μm。第一通孔4的孔径小而毛细作用强，可有效提高气溶胶形成基质传输效率，且第一通孔4的孔径小使得形成的烟雾粒径小。此外增加第一通孔4的数量，第一通孔4的数量增加使得成雾核心的数量增加，形成的烟雾更均匀。
在其中一些实施例中，雾化芯还包括用于供外部电源与发热件2电性连接的两个电极7，电极7设于发热件2或结合件3上，以方便发热件2与外部电源电性连接。电极7可以是但不限于通过印刷工艺形成于发热件2或结合件3上，发热件2为发热层时，发热层的厚度为10nm～30μm，结合件3的厚度为100um～2000um，结合件3的厚度设置需要考虑雾化芯强度和制造成本，结合件3的厚度小于100um时，雾化芯的强度不足，结合件3的厚度大于2000um时，雾化芯的制造成本较高。相应地，当结合件3为石英玻璃结合层或结合板 时，石英玻璃结合层或结合板的厚度控制在300～1000um之间，以保证贯穿设置于石英玻璃结合层或结合板上的第一通孔4具有一定的轴向长度，延长气溶胶形成基质流经第一通孔4的时间，有利于气溶胶形成基质均匀受热雾化。此外，在石英玻璃结合层或结合板上通过印刷工艺形成电极7，使得电极7的设置位置不受限制，既可图形化处理电极7，更加有利于优化电极7的位置分布，而且可增强电极7结合的牢固性，有效防止电极脱落，延长雾化芯的使用寿命。而且，石英玻璃为医用级材料，具有安全可靠的优点，因此，采用石英玻璃结合层或结合板的雾化芯同样具有安全可靠的优势。

本发明实施例还提供一种气溶胶发生装置，气溶胶发生装置包括上述任一实施例提供的雾化芯或上述任一实施例提供的的雾化器。因气溶胶发生装置具有上述任一实施例提供的雾化芯或雾化器的全部技术特征，故其具有雾化芯相同的技术效果。
本发明实施例还提供一种可制备上述雾化芯的雾化芯制备方法，本发明实施例中的雾化芯制备方法包括如下步骤：
步骤S1，有机高分子基体制备：选用聚二甲基硅氧烷(PDMS)、聚酰胺(PI)、聚甲基丙烯酸甲酯(PMMA)、聚碳酸酯(PC)、聚对苯二甲酸乙二醇酯(PET)中的至少一种高分子材料制备得到可吸附及传导气溶胶形成基质的有机高分子基体，此时有机高分子基体可构成多孔高分子吸液件1。其中，由于聚二甲基硅氧烷(PDMS)与气溶胶形成基质具有较好的浸润性，具备优良的改性的能力，安全无毒，化学稳定性比较高，在-60～300℃的使用环境中不会发生物理化学变化，优先选用聚二甲基硅氧烷(PDMS)制备得到可吸附及传输气溶胶形成基质的有机高分子基体。
步骤S2，结合件制备：选用硅、玻璃、不锈钢中的至少一种材料制备得到 结合件3，并采用开孔工艺在结合件3上加工出若干第一通孔4，以获得开孔结合件3。
步骤S3，键合连接：采用键合技术将开孔结合件3与有机高分子基体进行键合连接，以使开孔结合件3无缝隙地紧密贴合于多孔高分子吸液件1的表面上。
步骤S4，发热件制备：在开孔结合件3背离多孔高分子吸液件1的一面上形成单质金属发热层或合金发热层，以使开孔结合件3构成可将发热层结合并支撑于有机高分子基体的表面上的结合件3。
步骤S5，电极制备步骤：采用厚膜印刷工艺，在发热层或结合件3上形成两个电极7。
上述有机高分子基体制备步骤S1中，有机高分子材料可以是但不限于PDMS、PMMA、PI、PC、PET中的至少一种。
上述有机高分子基体制备步骤中，在所述有机高分子基体制备步骤中，还包括以下步骤：选择性地对所述有机高分子基体进行亲油疏水或亲水疏油特性改性。可以理解地，为了使得PMMA、PI、PC、PET等有机高分子材料制备的有机高分子基体具有良好的亲油疏水或亲水疏油特性，可选择性地针对有机高分子基体进行改性，改性方法包括但不限于紫外/臭氧改性法、等离子体改性法、表面活化剂法、接枝共聚法、电晕放电仪法中的至少一种，有机高分子基体的孔隙率为30～80％，有机高分子基体的孔径为1～100μm。具体地，针对上述步骤S1中的有机高分子基体的改性，以紫外臭氧改性法对有机高分子基体样品进行改性为例进行说明：(1)样品清洗干净备用；(2)将样品面向上放置，置于一真空腔室中；(3)样品正上方5mm处，安装有准分子紫外灯；(4)将腔室真空度抽至1Pa左右，通入臭氧，打开准分子紫外灯，照射24h。
上述有机高分子基体制备步骤中，还包括以下步骤：选择性地将所述有机高分子基体与骨架基体通过复合工艺进行组合，获得有机-无机复合基体。有机高分子基体可以是但不限于多孔PDMS基体、多孔PMMA基体、多孔PI基体、 多孔PC基体和多孔PET基体中的至少一种，骨架基体可以是但不限于氧化物基体、氮化物基体、碳化物基体、硼化物基体、硅化物基体和氟化物基体中的至少一种。具体地，作为一种可实施方案，可将多孔PDMS基体与硅藻土基体复合而成有机-无机复合基体，也可以将多孔PI基体与硅藻土基体复合而成有机-无机复合基体。
需要说明的是，上述步骤S1中根据使用场景的需要，选择性采用改性方法对有机高分子基体进行亲油疏水或亲水疏油特性的改性。例如，根据雾化芯使用场景来进行此部分工作，以选用聚二甲基硅氧烷(PDMS)制备得到可吸附及传输气溶胶形成基质的有机高分子基体为例，由于多孔PDMS基体具有较低的表面自由能，拥有极强的亲油、疏水能力，其亲油疏水特性在雾化气溶胶形成基质的应用场景不需要做改性；但是，在水溶性溶液使用场景需对多孔PDMS基体进行亲水疏油改性。
上述开孔结合件制备步骤S2中，第一通孔4形状包括但不限于圆形、方形、菱形、矩形、锥形、不规则形状等；当结合件3为硅板或硅层时，开孔工艺包括但不限于湿法刻蚀、干法刻蚀、激光烧蚀等。当结合件3为玻璃板或玻璃层时，开孔工艺包括但不限于喷砂法、光敏玻璃法、聚焦放电法、等离子刻蚀法、激光烧蚀法、电化学法、激光诱导刻蚀法。当结合件3为不锈钢板时，开孔工艺包括但不限于湿法腐蚀、激光烧蚀等。可以理解地，上述开孔结合件制备步骤S2中，也可以采用有序孔开孔工艺在结合件3上开设若干第一通孔4，以制备获得有序孔结合件3，有序孔结合件3可提高气溶胶形成基质传输的速率与均匀性。
上述键合连接步骤S3中，采用键合技术将开孔结合件3键合连接于有机高分子基体的表面，使得开孔结合件3能够无缝隙地紧密贴合于有机高分子基体的表面，使得有机高分子基体中气溶胶形成基质，能够通过开孔结合件3上的第一通孔4充分地传输至发热层，有效避免干烧。键合技术包括但不限于胶键合、热键合、阳极键合技术等。
上述发热层制备S4中，发热层采用厚膜印刷或薄膜沉积工艺形成于结合件3上，制备发热层的材料包括但不限于Pt、Pb、Rh、NiCr等单质金属或合金。发热层的制备方法包括但不限于厚膜印刷、薄膜沉积等，其中薄膜沉积方法包括但不限于物理气相沉积(磁控溅射、电子束蒸发、热蒸发、ALD等)和化学气相沉积(PECVD、MOCVD等)。当采用PVD工艺制备发热层时，发热层的厚度控制在10nm～5um。当采用印刷工艺制备发热层时，发热层的厚度控制在5～30um。
上述步骤S5中的电极制备步骤中，其中一种方式是先在结合件3上形成电极7，然后在结合件3以及电极7上制备发热层；其中另一种方式是先在结合件3上制备发热层2，然后在发热层2上形成电极7。需要注意的是，先在结合件3上制备发热层2，然后在结合件3上形成电极7，需要保证发热层2与两个电极7电性连接。
本发明实施例提供的雾化芯制备方法，与现有技术相比，选用有机高分子材料制备得到可吸附及传导气溶胶形成基质的有机高分子基体，并选择性对有机高分子基体进行亲油疏水或亲水疏油特性的改性，以及选择性将有机高分子基体与骨架基体通过复合工艺组合成有机-无机复合基体，以获得多孔高分子吸液件1。接着在有机高分子基体的表面键合连接具有第一通孔4的结合件3，并在结合件3形成发热层。由于气溶胶形成基质中的有机物的表面张力与多孔高分子吸液件1表面自由能相近，且多孔高分子吸液件1具有良好的亲油疏水或亲水疏油特性，在有效提高气溶胶形成基质传输效率的同时，能够将气溶胶形成基质中的香精或尼古丁等有效成分充分地传输至发热层，以提高香气的还原度及烟雾的浓郁度。此外，采用包括有机高分子基体的多孔高分子吸液件1代替多孔陶瓷吸液件，可有效提高气溶胶形成基质传输效率，能够良好地避免由于气溶胶形成基质供应不足而产生的雾化芯干烧积碳现象。
上述步骤S1中的有机高分子基体制备(以有机高分子基体为多孔PDMS基体为例)：(1)按照PDMS、固化剂、二甲基硅油的质量比10:1:10称取原 料组分，并将各原料组分置于一洁净烧杯中，充分搅拌至混合均匀，形成PDMS溶液。(2)向上述步骤(1)中的PDMS溶液中加入造孔剂，造孔剂可选用NaCl颗粒或白砂糖颗粒，超声分散后置于离心管中，并在10000rpm离心5min，以确保NaCl颗粒或白沙糖充分进入PDMS溶液的内部。离心结束后，使用吸管小心去除上清液，然后置于80℃的干燥箱中聚合2h，聚合得到PDMS弹性体。(3)将上述步骤(2)中的PDMS弹性体分别置于无水乙醇和去离子水中，超声洗涤2～3次以除掉NaCl颗粒或白砂糖颗粒和多余的二甲基硅油，最后将PDMS弹性体置于真空恒温干燥箱中，80℃干燥12h，得到多孔PDMS材料。由于多孔PDMS基体具有较低的表面自由能，拥有极强的亲油、疏水能力，因此可通过PDMS材料可制备得到具有良好的亲油疏水的有机高分子基体。需要注意的是，除PDMS高分子材料以外的高分子材料，如PMMA材料、PI材料、PC材料、MOFs材料或PET材料等，根据使用场景的需要，可通过紫外/臭氧改性法、等离子体改性法、表面活化剂法、接枝共聚法、电晕放电仪法中的至少一种改性方法，对高分子材料制成的有机高分子基体进行亲油疏水或亲水疏油改性后，才能制备获得具有良好的亲油疏水或亲水疏油特性的有机高分子基体。但是，如果雾化芯使用场景为水溶性溶液，则需要通过紫外/臭氧改性法、等离子体改性法、表面活化剂法、接枝共聚法、电晕放电仪法中的至少一种改性方法对多孔PDMS基体进行亲水疏油改性。
上述步骤S2中的开孔结合件3制备(以石英玻璃为例)：(1)将石英玻璃依次进行丙酮、无水乙醇、去离子水超声清洗，烘干备用；(2)通过皮秒激光在石英玻璃上产生变性区域，被激光照射后，玻璃变得容易被腐蚀液腐蚀；(3)将激光处理过的玻璃放到氢氟酸溶液中进行刻蚀，形成有序孔玻璃板。
上述步骤S3中的有机高分子基体与开孔结合件3键合连接(以多孔PDMS基体与石英玻璃为例)：(1)将制备得到的多孔PDMS基体、有序孔玻璃板清洗干净，保持表面清洁；(2)将上述多孔PDMS基体放入等离子清洗机内，将腔室真空度抽至13.33Pa；(3)用氧气反复冲洗真空腔室至少2次；(4)调 节腔室至氧气压力为20Pa左右；(5)打开射频电源使氧气电离，产生氧等离子体轰击多孔PDMS基体，持续1min左右；(6)将多孔PDMS基体取出，即可与有序孔玻璃板完成永久性键合，无缝隙贴合在一起。
上述PDMS与石英玻璃键合连接时，氧等离子体处理后的PDMS，其表面引入了-OH基团，并代替了-CH基团，形成Si-OH键。石英玻璃表面含有大量Si-O键，在氧等离子体处理的过程中，Si-O键被打断，从而表面形成大量的Si悬挂键，通过吸收空气中-OH，形成了Si-OH键。将处理后的PDMS与石英玻璃表面相贴合，两表面的Si-OH之间发生如下反应：2Si-OH→Si-O-Si+2H2O，从而在石英玻璃和PDMS之间形成了牢固的Si-O键结合。
上述步骤S4中的发热层的制备(以电阻比较稳定，而且高温下不容易氧化的铂金为例)：(1)将键合好的样品清洗洁净备用；(2)将样品石英玻璃面向上放置，传递至磁控溅射真空腔室中；(3)将真空腔室真空度，抽至10-4Pa，开始通入工作气体Ar，Ar流量设置为60sccm，直流电源功率设置为150W，衬底盘转速为20rpm；(镀膜前，把镀膜的环境抽到一个高真空的状态)(4)调节真空腔室真空度为1.0Pa，打开靶材挡板，依次沉积Ti和Pt，Ti作为粘附层。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
