具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的技术特征可以相互组合，具体实施方式中的详细描述应理解为本申请宗旨 的解释说明，不应视为对本申请的不当限制。
本申请中，多个包括两个以及两个以上。单位“mm”为毫米。
相关技术中，由于相关技术中的气溶胶生成基质的实体介质的密度较高，气溶胶难以在短时间内在气溶胶生成基质的内部流通，或者难以从气溶胶生成基质的实体介质中释放到外界，因此，导致气溶胶无法及时释放，气溶胶的提取效率大大降低。
本申请实施例提供一种气溶胶生成基质，请参阅图1至图5，气溶胶生成基质包括基础部1和多个子单元2，多个子单元2位于基础部1沿第一方向的外侧，多个子单元2沿基础部1的第二方向间隔设置，相邻的两个子单元2之间的空间为间隙空间2a，其中，第一方向和第二方向相交。也就是说，气溶胶生成基质的外表面是非连续的面。间隙空间2a用于汇集和流通气溶胶。
需要说明的是，本申请实施例中，气溶胶生成基质用于加热产生气溶胶。示例性的，气溶胶生成基质可以适用于加热不燃烧的方式产生气溶胶。也就是说，气溶胶生成基质被加热至着火点以下以产生气溶胶。气溶胶生成基质在产生气溶胶的过程中不燃烧。在一些应用场景中，气溶胶生成基质可以适用于点燃的方式产生气溶胶。本申请气溶胶生成基质更多的应用于加热不燃烧的方式产生气溶胶。
本申请实施例还提供一种气溶胶生成制品，气溶胶生成制品包括本申请任一项实施例中的气溶胶生成基质和功能段，功能段设置于气溶胶生成基质沿第三方向的一端，功能段至少包括用于过滤气溶胶的过滤段。过滤段用于过滤气溶胶生成基质产生的气溶胶。
气溶胶生成制品用于供用户吸食气溶胶生成基质产生的气溶胶。例如用户可以通过口含过滤段抽吸过滤后的气溶胶。气溶胶生成基质产生的气溶胶在抽吸负压作用下输送到过滤段。
气溶胶生成制品用于与具有加热件的电子雾化装置配合使用。
本申请实施例提供的电子雾化装置，电子雾化装置包括本申请任一项实施例中的气溶胶生成制品和加热件，加热件设置于子单元2沿第一方向的外侧，加热件用于加热气溶胶生成基质以产生气溶胶。
加热件设置于子单元2的外侧，以对气溶胶生成基质进行从外到内的烘烤加热。例如，加热件从子单元2的外侧加热子单元2，热量可以通过子单元2传递至基础部1。也就是说，热量由外至内传递。
加热件的发热方式包括但不限于电阻发热、电磁发热、红外发热、微波发热或者激光发热等。其中，加热件可以与子单元2的外表面接触或不接触。热对流的形式传递热量是指加热件不与气溶胶生成基质接触，加热件先对空气进行加热，然后热空气对气溶胶生成基质进行烘烤加热。热传导是指加热件与气溶胶生成基质接触并将热量传导至气溶胶生成基质。示例性的，电阻、电磁发热主要以热传导形式或者热对流形式向气溶胶生成基质传递热量。红外发热、微波发热或者激光发热主要以热辐射的形式向气溶胶生成基质传递热量。即加热件可以通过热传导、热对流及热辐射三种形式的一种或一种以上方式对气溶胶生成基质进行加热。
一实施例中，加热件为激光加热器。激光加热器是发出激光对气溶胶生成基质加热的器件。由于激光具有能量高度集中、及时性高的特点，可以实现快速产生气溶胶的目的。及时性高是指激光加热和停止加热的时间均很短，也就是说，激光能够在短时间内加热气溶胶生成基质产生气溶胶，也能够在短时间内停止加热气溶胶生成基质，因此，需要气溶胶生成基质能够及时释放产生的气溶胶，避免气溶胶积存。
示例性的，加热件包括但不限于激光二极管、半导体激光器、氦氖激光器、单模激光器或多模激光器等等。
本申请实施例中，子单元2的外表面先接收热量再传递至基础部1，热 量由外至内传递，气溶胶生成基质具有间隙空间2a，间隙空间2a起到汇集和流通气溶胶的作用，子单元2的释烟方向不单包括向外、向内，还可以向第二方向两侧的间隙空间2a释放气溶胶，畅通了气溶胶的释放路径，避免气溶胶无法及时释放的情况，因此，可以提高气溶胶的提取效率。
一实施例中，气溶胶生成基质的外侧被配置有发热层，发热层设置于子单元2的外表面并能够加热子单元2。如此能够增加传导至子单元2的热量。发热层能够覆盖相邻两个子单元2的外表面之间的间隔口，从而起到限制间隙空间2a内的气溶胶和外界空气沿第三方向流动的导流作用，能够加大空气进入量和提升气溶胶提取效率。由于气溶胶能够向外、向内、向第二方向两侧的间隙空间2a等多个方向释放，能够降低发热层发生鼓包而降低外表面与发热层之间的热传递效率的风险。
发热层的具体结构不限，示例性的，发热层为吸光层。也就是说，发热层可以是吸收光束并发热。例如，发热层可以吸收激光并散发热量。
一实施例中，请参阅图1，子单元2位于气溶胶生成基质沿第一方向的最外侧。也就是说，气溶胶生成基质的其他部位均位于子单元2沿第一方向的内侧，子单元2的外周面即为气溶胶生成基质的外周面。子单元2为气溶胶生成基质最靠近发热层的部位。
一实施例中，请参阅图2和图7，子单元2包括第一部分21和第二部分22，第二部分22和第一部分21沿第一方向排列，第一部分21沿第二方向的尺寸W2大于第二部分22沿第二方向的尺寸W3。
一实施例中，请参阅图1至图6，第二部分22连接基础部1和第一部分21。也就是说，第一部分21位于第二部分22的外侧，这样，第一部分21被激光照射或者接收吸光层传导的热量后，第一部分21向外、内、第二方向等各个方向释放气溶胶。另外，第二部分22及基础部1也会由于热传导作用而被加热(被加热的程度小于第一部分21被加热的程度)，被加热 产生的气溶胶也会释放到的间隙空间2a中。由于第一部分21沿第二方向的尺寸W2大于第二部分22沿第二方向的尺寸W3，因此，第一部分21的外表面的面积较大。由于激光发热的能量集中度大，子单元2与激光初步接触的介质面积越大越好，这样，有足够的实体介质承接激光产生的能量，以便释放较多的气溶胶。
需要说明的是，子单元2的外表面例如第一部分21的外表面可以用于接收激光照射产生的热量，子单元2的外表面可以由激光直接照射，也可以是激光照射到吸光层后，吸光层发热并加热子单元2。
一实施例中，第一部分21连接基础部1和第二部分22。也就是说，第二部分22位于第一部分21的外侧，这样，第二部分22被激光照射或者接收吸光层传导的热量后，第二部分22向各个方向释放气溶胶。另外，第一部分21及基础部1也会由于热传导作用而被加热，被加热产生的气溶胶也会释放到的间隙空间2a中。由于第二部分22沿第二方向的尺寸W3小于第一部分21沿第二方向的尺寸W2，因此，第二部分22的外表面的面积较小，释放的气溶胶相对较少。
一实施例中，请参阅图1，以垂直于第三方向的平面为截面，子单元2任意一个位置处的截面相同，其中，第一方向和第三方向相互垂直。截面相同包括截面形状和截面面积两者均相同。也就是说，在第三方向上，子单元2的截面保持一致。示例性的，以垂直于第三方向的平面为截面，第一部分21任意一个位置处的截面相同并且第二部分22任意一个位置处的截面相同。
一实施例中，请参阅图1和图2，间隙空间2a贯穿子单元2沿第三方向的两端。气流可以从子单元2沿第三方向的一端流动至另一端。如此，空气携带气溶胶形成的气流能够更顺畅地流动，气流流动阻力更小，能够较为显著地降低抽吸过程中的抽吸阻力，提升抽吸体验。
一实施例中，气溶胶生成基质为一体结构。例如，气溶胶生成基质为挤出成型的一体结构。挤出成型是指物料通过挤出装置的料筒和挤出螺杆之间的相互作用，物料受热塑化并被挤出螺杆向出料口推送，通过挤出模具例如口模制成预设投影形状及具有相应孔隙的气溶胶生成基质的一种加工方法。示例性的，可以通过挤出成型形成基础部1、子单元2和间隙空间2a。如此，在气溶胶生成基质使用过程中例如受热抽吸或停止受热后均为一体介质，不易出现崩解掉落的问题。
需要说明的是，第三方向是指气溶胶生成基质的延伸方向。例如，气溶胶生成基质采用挤出成型，第三方向是气溶胶生成基质的挤出方向。投影形状是指以垂直于第三方向的平面为投影面气溶胶生成基质呈现的形状。
一实施例中，请参阅图1至图7，第一部分21呈沿第二方向延伸的板状结构，第二部分22呈沿第一方向延伸的板状结构。也就是说，第一部分21和第二部分22均为实体介质。如此设计，第一部分21和第二部分22结构简单，易于制造。
一实施例中，请参阅图12，子单元2包括一个第一部分21和多个第二部分22，多个第二部分22沿第二方向间隔布置并位于第一部分21的内侧，第二部分22连接基础部1和第一部分21。一方面，可以通过多个第二部分22增加子单元2的实体介质的质量，介质质量越多能够产生的气溶胶的质量越多，从而提高能够释放气溶胶的总量。另一方面，多个第二部分22沿第二方向间隔布置，相邻的两个第二部分22之间具有间隙，以便于气溶胶的流通，还便于热量穿透该间隙进入内侧。又一方面，还可以通过多个第二部分22增加对第一部分21的支撑，使得第一部分21能够更好地维持形态，减少第一部分21的形变，这样，既能够兼顾气溶胶释放量，又能够兼顾气溶胶流通。
示例性的，一实施例中，请参阅图12，第一部分21和第二部分22均为板状结构，子单元2包括一个第一部分21和两个第二部分22，以垂直于第三方向的平面为投影面，一个第一部分21的投影和两个第二部分22的投影共同呈π字型。
一实施例中，请参阅图1至图11，子单元2包括一个第一部分21和一个第二部分22，第一部分21和第二部分22均为板状结构。以垂直于第三方向的平面为投影面，一个第一部分21的投影和一个第二部分22的投影两者共同呈T字型。
一实施例中，请参阅图7，第一部分21和第二部分22均为等壁厚结构，且第一部分21的壁厚H1和第二部分22的壁厚相等。
需要说明的是，等壁厚结构是指介质壁的厚度处处相等的结构。
一实施例中，请参阅图8，第一部分21为等壁厚结构，第二部分22的壁厚从靠近第一部分21向远离第一部分21逐渐增大。
一实施例中，请参阅图9，第一部分21的边角处均倒圆角，且第一部分21和第二部分22的连接处倒圆角。如此可以减少边角处和连接处尖锐拐角造成应力集中而出现破损的情况。
一实施例中，请参阅图10，第一部分21和第二部分22的连接处倒角。也就是说，第一部分21和第二部分22的连接处的壁厚从靠近第二部分22向远离第二部分22逐渐增大。以垂直于第三方向的平面为投影面，一个第一部分21的投影和一个第二部分22的投影两者共同呈T字型，第一部分21和第二部分22的连接处呈梯形。
一实施例中，请参阅图11，第一部分21沿第二方向的两端的壁厚均大于第一部分21其余部位的壁厚。
一实施例中，请参阅图2，相邻的两个第一部分21沿第二方向的间距为第一间距L，第一部分21沿第二方向的尺寸W2与第一间距L的比值在 10:1至1:1之间。示例性的，第一部分21沿第二方向的尺寸W2与第一间距L的比值为10:1、9:1、8:1、7:1、6:1、5.5:1、5.5:1、5:1、3:1或者1:1等等。
该实施例中，如果第一部分21沿第二方向的尺寸W2与第一间距L的比值大于10:1，则第一部分21的介质质量较多，而第一间距L相对较小，这样，生成的气溶胶较多而用于流通气溶胶的间隙空间2a相对较小，抽吸阻力较大，另外，第一间距L越小，气溶胶生成基质的制造工艺例如挤出工艺越复杂，气溶胶生成基质越难以挤出成型，良品率越低。如果第一部分21沿第二方向的尺寸W2与第一间距L的比值小于1:1，则第一部分21的介质质量较少，而第一间距L相对较大，这样，生成的气溶胶较少而用于流通气溶胶的间隙空间2a相对较大，产生的气溶胶难以满足抽吸需求。因此，第一部分21沿第二方向的尺寸W2与第一间距L的比值在10:1至1:1之间，在保证气溶胶生成基质制造良品率较高的条件下，能够最大限度保证气溶胶有效提取，能够均衡气溶胶释放量和抽吸阻力，用户体验感好。
一实施例中，请参阅图7，第一部分21的壁厚H1为0.1mm至0.5mm。示例性的，第一部分21的壁厚H1为0.1mm、0.2mm、0.3mm、0.35mm、0.4mm或者0.5mm等等。如果第一部分21的壁厚H1小于0.1mm，第一部分21的壁厚H1太小，单位面积内实体介质生成的气溶胶释放量太少，而且第一部分21容易变形。如果第一部分21的壁厚H1大于0.5mm，第一部分21第一方向上生成的气溶胶难以有效释放。如此，第一部分21的壁厚H1适中，既有较好的结构强度，易于制造例如挤出成型，又能够产生适宜的气溶胶释放量，并能够快速释放，以被用户吸食。
一实施例中，请参阅图7，第二部分22沿第一方向的尺寸W1为0.5mm至5mm。第二部分22沿第一方向的尺寸W1为0.5mm、0.6mm、0.9mm、1mm、1.5mm、2mm、2.5mm、3mm、3.5mm、4mm、4.5mm、4.8mm或者 5mm等等。如果第二部分22沿第一方向的尺寸W1小于0.5mm，则第二部分22与基础部1之间的距离较近，间隙空间2a沿第一方向的尺寸较窄，供气溶胶流通的空间不足，不易抽吸。如果第二部分22沿第一方向的尺寸W1大于5mm，第二部分22制造过程中容易变形，良品率低。第二部分22沿第一方向的尺寸W1为0.5mm至5mm，如此，第二部分22沿第一方向的尺寸W1适中，既有较好的结构强度，易于制造例如挤出成型，又便于抽吸。
一实施例中，请参阅图7，第一部分21沿第二方向的尺寸W2与第二部分22沿第一方向的尺寸W1的比值为1:2至2:1。如果第一部分21沿第二方向的尺寸W2与第二部分22沿第一方向的尺寸W1的比值小于1:2，则容易发生气溶胶释放量不足或者第二部分22变形的问题。如果第一部分21沿第二方向的尺寸W2与第二部分22沿第一方向的尺寸W1的比值大于2:1，则间隙空间2a的容积不足，气溶胶流通空间过小，不易抽吸。因此，第一部分21沿第二方向的尺寸W2与第二部分22沿第一方向的尺寸W1的比值为1:2至2:1，如此，子单元2既有较好的结构强度，易于制造例如挤出成型，又能够保证间隙空间2a的空间充足，便于抽吸。
一实施例中，气溶胶生成基质的最大壁厚与最小壁厚两者之差为第一差值，第一差值与气溶胶生成基质的最小壁厚的百分比为0％至100％。也就是说，气溶胶生成基质的最大壁厚不大于最小壁厚的一倍。如果气溶胶生成基质的最大壁厚大于最小壁厚的一倍，即，第一差值与气溶胶生成基质的最小壁厚的百分比大于100％，则气溶胶生成基质的各部位的壁厚差异过大，容易造成制造过程中例如挤出过程中，气溶胶生成基质的部分结构难以成型，例如难以挤出的情况。
一实施例中，第一差值与气溶胶生成基质的最小壁厚的百分比为0％，即气溶胶生成基质各部位的壁厚均相等。例如，第一部分21、第二部分22 和基础部1的壁厚均相等，气溶胶生成基质各部位的壁厚具有较高的一致性，能够防止制造过程中例如挤出过程中，气溶胶生成基质的部分结构难以成型，例如难以挤出的情况，提高良品率。
一实施例中，请参阅图2，以垂直于第三方向的平面为投影面，气溶胶生成基质的投影形状的水力直径D为5mm至15mm。示例性的，气溶胶生成基质的投影形状的水力直径D为5mm、6mm、9mm、10mm、11mm、12mm、13mm、14mm或者15mm等等。一方面，便于气溶胶生成基质适配手持式的电子雾化装置；另一方面，气溶胶生成基质从外侧向内侧传递热量的时间适中，以便于在抽吸过程中，均衡释放气溶胶；又一方面，气溶胶生成基质的气溶胶的总释放量适宜，气溶胶的总的释放时长适中，也就是说，气溶胶生成基质的使用寿命适中，保证抽吸次数适于客户需求，避免抽吸量不够或过量浪费等情况，用户抽吸体验好。
需要理解的是，气溶胶生成基质的投影形状是指气溶胶生成基质的投影面的轮廓形状。例如，气溶胶生成基质的投影形状是指基础部1、第一部分21、第二部分22和释放间隙共同构成的截面的外轮廓形状。以第一部分21位于第二部分22的外侧为例，气溶胶生成基质的投影形状是指所有子单元2的第一部分21的外侧面围设形成的外轮廓形状。
一实施例中，第一方向和第二方向相互垂直。示例性的，第一方向和第二方向为两个直线方向。请参阅图6，以气溶胶生成基质的投影形状为长方形为例，第一方向可以为宽度方向，第二方向可以为长度方向。
一实施例中，第一方向为径向，第二方向为周向。请参阅图1，以气溶胶生成基质的投影形状为圆形为例，第一方向可以为径向，第二方向可以为周向。
示例性的，一实施例中，以垂直于第三方向的平面为投影面，气溶胶生成基质的投影形状为圆形(请参阅图2和图4)、椭圆形或者多边形。多 边形包括但不限于正方形、长方形(请参阅图6)、五边形、六边形或者八边形等等。也就是说，气溶胶生成基质可以呈圆柱体、长方体或者棱柱体等等。
本申请实施例中，水力直径指的是投影形状的面积的四倍与周长之比。例如，气溶胶生成基质的投影形状为长方形，则水力直径是长方形的面积的四倍与长方形的周长之比。又例如，气溶胶生成基质的投影形状为圆形，水力直径即为圆形的直径。
一实施例中，子单元2的数量在6个至30个之间(包含6个和30个)。如此，所有子单元2的介质质量之和和所有释放间隙的容积之和适配，也就是说，气溶胶的释放量与气溶胶在释放间隙内的流量适配，使得气溶胶生成基质在加热过程中气溶胶释放均匀。
一实施例中，相邻的两个子单元2沿第二方向的最小间距为0.1mm至1mm。示例性的，相邻的两个子单元2沿第二方向的最小间距为0.1mm、0.2mm、0.3mm、0.4mm、0.5mm、0.6mm、0.8mm、0.9mm或者1mm等等。
示例性的，请参阅图2，相邻的两个子单元2沿第二方向的最小间距是相邻的两个第一部分21沿第二方向的第一间距L。也就是说，相邻的两个第一部分21沿第二方向的第一间距L为0.1mm至1mm(包含0.1mm和1mm)。
该实施例中，如果相邻的两个子单元2沿第二方向的最小间距小于0.1mm，则相邻的两个子单元2之间距离过近，间隙空间2a相对较小，抽吸阻力较大，另外，相邻的两个子单元2沿第二方向的最小间距越小，气溶胶生成基质的制造工艺例如挤出工艺越复杂，气溶胶生成基质越难以挤出成型，良品率越低。
如果相邻的两个子单元2沿第二方向的最小间距大于1mm，则子单元2的介质质量较少，这样，生成的气溶胶较少而用于流通气溶胶的间隙空间 2a相对较大，产生的气溶胶难以满足抽吸需求。
因此，相邻的两个子单元2沿第二方向的最小间距为0.1mm至1mm，在保证气溶胶生成基质制造良品率较高的条件下，能够均衡气溶胶释放量和抽吸阻力。
一实施例中，以垂直于第三方向的平面为投影面，所有子单元2的总投影面积与所有间隙空间2a的总投影面积的比值为1:9至1:1(包含1:9和1:1)。优选地，所有子单元2的总投影面积与所有间隙空间2a的总投影面积的比值为1:4至1:2(包含1:4和1:2)。
所有子单元2的总投影面积是指所有子单元2的投影面积之和。所有间隙空间2a的总投影面积是指所有间隙空间2a的投影面积之和。
该实施例中，如果所有子单元2的总投影面积与所有间隙空间2a的总投影面积的比值大于1:1，则子单元2的总的介质质量相对较高，而释放间隙的投影面积相对较小，气溶胶容易被实体介质吸附产生冷凝，气溶胶释放量不足，且实体介质的有效利用率低。如果所有子单元2的总投影面积与所有间隙空间2a的总投影面积的比值小于1:9，则释放间隙的投影面积相对较大，气溶胶的流速慢，不易被有效提取，不利于抽吸体验。
一实施例中，请参阅图5和图6，基础部1呈板状结构，基础部1的壁厚方向与第一方向平行。基础部1的壁厚、第一部分21的壁厚H1和第二部分22的壁厚可以基本一致，以便于制造成型例如挤出成型。
示例性的，一实施例中，请参阅图5和图6，基础部1、第一部分21和第二部分22均呈板状结构，气溶胶生成基质包括两个侧部3，所有子单元2位于两个侧部3之间，所有第二部分22和两个侧部3均与基础部1的外表面连接。气溶胶生成基质的投影形状呈长方形。
一实施例中，请参阅图1至图4，基础部1呈圆柱状结构。圆周状结构不仅便于在外周设置较多的子单元2，还便于成型例如挤出成型。
一实施例中，请参阅图1至图4，基础部1的内部形成有贯穿其沿第三方向至少一端的气道1a。气道1a也能汇集和流通气溶胶。基础部1释放的气溶胶能够通过气道1a快速流通，提高气溶胶的有效提取率。
一实施例中，请参阅图1至图4，气道1a贯穿基础部1沿第三方向的相对两端。气流可以从基础部1的一端沿第三方向流动至基础部1的另一端。如此，空气携带气溶胶形成的气流能够更顺畅地流动，气流流动阻力更小，能够较为显著地降低抽吸过程中的抽吸阻力，提升抽吸体验。
一实施例中，请参阅图1和图2，气道1a的数量可以为一个。
一实施例中，请参阅图3和图4，气道1a的数量为多个，多个气道1a间隔布置。一方面，多个气道1a能够进一步增加气溶胶生成基质的孔隙率，有利于热量的穿透和/或扩散，降低气溶胶流动阻力；另一方面，多个气道1a间隔布置，也就是说，各个气道1a之间具有介质壁，单个气道1a的孔径可以较小，介质质量适宜，基础部1的结构强度好。
一实施例中，气道1a为沿直线延伸的直线形气道1a。直线形气道1a易于成形，能够降低制造难度。直线形气道1a内气流的流动阻力相对较小。
一实施例中，气道1a为曲线形气道1a，曲线形气道1a的至少部分孔段呈曲率不为零的曲线形。曲线形气道1a能够在不显著增加气溶胶生成基质的长度的情况下，较大程度增加气流的流动路径，可以延长气流与曲线形气道1a的孔壁面的接触时长，从而提高气溶胶的提取率。
一实施例中，曲线形气道1a呈螺旋线形。也就是说，曲线形气道1a的立体形状呈空间螺旋线形。螺旋线形的曲线形气道1a的任意一点与起点的连线相对于其轴线具有倾斜角度。螺旋线形的曲线形气道1a可以极大地延长气流的流动路径，将气溶胶从气溶胶生成基质内析出至曲线形气道1a中，提高气溶胶在气溶胶生成基质内的流动速度，从而提高气流的冲击力，使气溶胶能得到均匀混合，提高气溶胶均匀性，提升用户的抽吸感受。
气道1a的投影形状不做限制，比如，气道1a的投影形状可以是圆形、多边形(包括但不限于三角形、正方形、棱形等)，椭圆形、跑道形或异形等，其中，异形是指前面所列举的形状之外的其它对称或非对称的形状。
需要说明的是，本申请实施中，除非特殊说明，否则投影面均是指垂直于第三方向的平面。
一实施例中，请参阅图3和图4，基础部1包括一个圆形气道1a和多个扇形气道1a，多个扇形气道1a环绕圆形气道1a间隔布置。
可以理解的是，多个气道1a也可以呈一维排列、二维矩阵排列或者呈多个同心圆排列等等。多个气道1a的排列方式不限。
示例性的，一实施例中，气道1a的数量为4个，4个气道1a均呈扇形，4个扇形气道1a均匀分布。这样，基础部1内的介质壁的投影大致呈“十”字型。一实施例中，气道1a的数量为8个，8个气道1a均呈扇形，8个扇形气道1a均匀分布。这样，基础部1内的介质壁的投影大致呈“米”字型。
需要说明的是，气溶胶生成基质的内部可以存在微孔，比如，对于颗粒结合体的气溶胶生成基质，颗粒与颗粒之间的间隙构成微孔，但是，本申请所述的气道1a与微孔不同，本申请所述的气道1a属于宏观意义上的孔，微孔属于微观意义上的孔，气道1a的投影面积以及长度等尺寸比微孔大的多。气道1a主要依靠设计加工而成，例如依靠口模加工而成，因此，气道1a的投影面积以及长度等尺寸可以根据设计要求而改变，而微孔的尺寸由颗粒与颗粒之间的间隙决定，例如，物料为颗粒状物料，物料挤出成型的气溶胶生成基质具有微孔，微孔的投影面积以及长度等尺寸通过挤出工艺及物料组份自然形成，物料加料筒流出模口后产生一定膨胀可以形成微孔。
一实施例中，至少部分子单元2的材质相同。例如，可以是部分子单元2的材质相同，另外部分子单元2的材质不同。又例如，可以是全部子单元2的材质相同。如此，制造设备简单，以挤出工艺为例，挤出机的结 构简单。
一实施例中，可以是全部子单元2的材质不同。这样，不同的子单元2可以释放不同口味的气溶胶，选择性更多。
一实施例中，至少部分子单元2的投影形状相同。例如，可以是部分子单元2的投影形状不同，且另外部分子单元2的投影形状相同。又例如，可以是全部子单元2的投影形状相同。如此，挤出机的模具例如口模结构简单。
一实施例中，可以是全部子单元2的投影形状不同。这样，可以提供更加清爽或者醇厚的口感，也可以匹配不同的加热方式，口感更加丰富。
一实施例中，可以是全部间隙空间2a的容积相同。
一实施例中，至少部分间隙空间2a的容积不同。例如，可以是部分间隙空间2a的容积不同，且另外部分间隙空间2a的容积相同。又例如，可以是全部间隙空间2a的容积不同。
一实施例中，至少部分子单元2沿第二方向均匀分布。例如，部分子单元2沿第二方向均匀分布，且另外部分子单元2沿第二方向不均匀分布。又例如，全部子单元2沿第二方向均匀分布。这样设计，气溶胶生成基质不同部位的介质质量分布趋近相同，并且气溶胶生成基质不同部位的间隙空间2a趋近相同，使得气溶胶生成基质不同部位的气溶胶的释放量和流动阻力趋于一致，这样，能够提高在抽吸过程中气溶胶释放均匀性，抽吸过程中每口的抽吸量趋于一致，从而提高抽吸一致性，抽吸体验好。
示例性的，一些实施例中，请参阅图1至图6，子单元2沿第二方向均匀分布的形式包括：各个子单元2的投影形状相同，并且各个间隙空间2a的投影形状相同。例如，各个子单元2的投影形状相同，各个子单元2沿板状的基础部1一维分布或绕圆柱状的基础部1同心圆分布。也就是说，各子单元2自身的排布形式呈均匀。
一实施例中，全部子单元2沿第二方向不均匀分布。这样，可以根据抽吸需求，不均匀分布的子单元2可以配合不同的加热方式，不仅可以实现气溶胶生成基质的均匀加热，还可以实现抽吸过程中开始的几口及结束的几口的气溶胶一致性。
一些实施例中，功能段可以只设置过滤段。
另一些实施例中，功能段还包括降温段，降温段位于过滤段与气溶胶生成基质之间，降温段用于在过滤段对气溶胶进行过滤之前，对气溶胶进行降温。降温段可以改善用户吸食气溶胶时的“烫嘴”现象。
降温段采用的降温材料包括但不限于PE(聚乙烯)、PLA(Polylactic Acid，聚乳酸)、PBAT(Polybutylene Adipate Terephthalate，聚己二酸对苯二甲酸丁二醇酯)、PP(Polypropylene，聚丙烯)、醋酸纤维、丙烯纤维等材料中的一种或多种组合。

植物原料用于在加热时产生气溶胶。助剂原料用于为植物原料提供骨架支撑。发烟剂原料用于在加热时可以产生大量烟雾。粘合剂原料用于粘结组分原料。香料原料用于提供特征香气。如此，植物原料和发烟剂原料能够保证气溶胶生成量，而香料原料能够提升抽吸过程中的香气的释放，提升用户体验。助剂原料不仅能够提高混合物料的流动性，还使得气溶胶生成基质呈多孔结构，以便于气溶胶的提取和流动。粘合剂原料保证植物 原料粉末和助剂等构成稳定地混合物，避免结构松散。
一实施例中，植物原料为烟叶原料、烟叶碎片、烟梗、烟末、香味植物等经破碎处理后形成的粉末中一种或多种组合。植物原料为香味的核心来源，植物原料中的内源物质可以给用户产生生理满足感，内源物质例如生物碱进入人体血液，促进脑垂体产生多巴胺，从而获得生理满足感。
一实施例中，助剂原料可以为无机填料、润滑剂、乳化剂中一种或多种组合。其中，无机填料包括重质碳酸钙、轻质碳酸钙、沸石、凹凸棒石、滑石粉、硅藻土中一种或多种组合。无机填料可以为植物原料提供骨架支撑作用，同时无机填料还具有微孔，可以提高气溶胶生成基质的孔隙率，从而提高气溶胶释放率。
润滑剂包括小烛树蜡、巴西棕榈蜡、虫胶、向日葵蜡、米糠、蜂蜡、硬脂酸、软脂酸中一种或多种组合。润滑剂可以增加植物原料粉末的流动性，减少植物原料粉末相互间的摩擦力，可使植物原料粉末分布的整体密度较为均匀，也能降低用于挤压成型过程中所需的压力，降低口模的磨损。
乳化剂包括聚甘油脂肪酸酯、吐温-80、聚乙烯醇中一种或多种组合。乳化剂在一定程度上能够减缓香味物质在储存过程中的损失，增加香味物质的稳定性，提高产品的感官品质。
一实施例中，发烟剂原料可以包括：一元醇(如薄荷醇)；多元醇(如丙二醇、丙三醇、三乙二醇、1,3-丁二醇和四乙二醇)；多元醇的酯(如三乙酸甘油酯、柠檬酸三乙酯、二乙酸甘油酯混合物、柠檬酸三乙酯、苯甲酸苯甲酯、甘油三丁酸酯)；单羧酸；二元羧酸；多元羧酸(如月桂酸、肉豆蔻酸)或多元羧酸的脂肪族酯(如十二烷二酸二甲酯、十四烷二酸二甲酯、赤藻糖醇、1,3-丁二醇、四乙二醇、柠檬酸三乙酯、碳酸亚丙酯、月桂酸乙酯、特瑞克汀(Triactin)、内消旋赤藻糖醇、二乙酸甘油酯混合物、辛二酸二乙酯、柠檬酸三乙酯、苯甲酸苯甲酯、苯基乙酸苯甲酯、香草酸乙酯、甘 油三丁酸酯、乙酸月桂酯)中一种或多种组合。
