本申请涉及气溶胶生成技术领域，特别是涉及一种气溶胶生成基质、气溶胶生成制品和电子雾化装置。
背景技术
气溶胶生成基质可以通过点燃的方式形成气溶胶，或者通过加热而不燃烧的方式形成气溶胶。以加热而不燃烧的气溶胶生成基质为例，气溶胶生成基质利用外部热源加热，使气溶胶生成基质刚好加热到足以散发出气溶胶的程度，气溶胶生成基质不会燃烧，使用时通过加热气溶胶生成基质释放气溶胶。
相关技术中，采用周圈或者中心加热气溶胶生成基质，中心加热是指加热件插入气溶胶生成基质内部对气溶胶生成基质从内到外进行烘烤加热。周圈加热是指加热件设置在气溶胶生成基质的外围，以对气溶胶生成基质进行从外到内的烘烤加热，然而，在气溶胶生成基质的加热过程中，存在气溶胶释放较快或者较慢等一致性差的问题。
发明内容
有鉴于此，本申请实施例期望提供一种气溶胶生成基质、气溶胶生成 制品和电子雾化装置，能够提高气溶胶释放一致性。
为达到上述目的，本申请实施例提供了一种气溶胶生成基质，包括：

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，多个包括数量为两个以及两个以上。单位“mm”为毫米。
相关技术中，如果使用周圈加热，热量传递方向是沿径向由外周往中心传热。在传热过程中，气溶胶生成基质的周长逐渐缩小，也就是说，被加热的介质的体积逐渐缩小，被加热的介质质量逐渐减少，若不控制传热速率，则容易导致抽吸前段气溶胶等有效物质释放过快，满足感过强，而抽吸后段衰减严重的问题。如果使用中心加热，热量传递方向是沿径向由中心往外周传热。在传热过程中，气溶胶生成基质的周长逐渐增大，也就是说，被加热的介质的体积逐渐增大，被加热的介质质量逐渐增加，若不控制传热速率，则容易导致抽吸前段气溶胶等有效物质释放较慢，前几口口感不佳，而抽吸后段中心区域烘烤过度引起杂气的问题。
有鉴于此，请参阅图1，本申请实施例提供一种气溶胶生成基质10，气溶胶生成基质10包括基础段1和调节段2。
基础段1和调节段2沿径向套设。示例性的，一些实施例中，基础段1套设于调节段2内。另一些实施例中，调节段2套设于基础段1内。
基础段1和调节段2其中一个沿径向的一个表面为加热面。示例性的，一些实施例中，基础段1沿径向的一个表面为加热面。另一些实施例中，调节段2沿径向的一个表面为加热面。加热面用于朝向加热件以接收来自加热件的热量。
调节段2和基础段1两者的至少一个参数不同，参数包括导热率、质量、介质的壁厚H以及介质的总横截面积。示例性的，一些实施例中，调节段2和基础段1两者一个参数不同，例如，可以是导热率、质量、介质的壁厚H和介质的总横截面积其中一个不同。另一些实施例中，调节段2和基础段1两者两个参数不同，例如，可以是导热率、质量、介质的壁厚H和介质的总横截面积其中两个不同。又一些实施例中，调节段2和基础段1两者三个参数不同，例如，可以是导热率、质量、介质的壁厚H和介质的总横截面积其中三个不同。再一些实施例中，调节段2和基础段1两者四个参数不同，例如，可以是导热率、质量、介质的壁厚H和介质的总横截面积四个全部不同。
导热率，又称导热系数或热导率，是指单位温度梯度在单位时间内经单位导热面所传递的热量。导热率是表示结构热传导能力大小的物理量。基础段1和调节段2的导热率不同，使得调节段2和基础段1两者的传热速率不同。
示例性的，基础段1和调节段2可以采用不同的材料，实现不同的导热率。
介质是指围设形成空间的实体结构。以调节段2形成有第一气道2a为 例，介质围设形成第一气道2a。请参阅图1，介质的壁厚H是指以垂直于轴向的平面为横截面，介质在横截面内的厚度尺寸。由于介质的壁厚H不同，热量传导过程中的传热路径的尺寸不同，使得调节段2和基础段1两者的传热速率不同。
调节段2和基础段1两者的质量不同，这样能够释放气溶胶的介质的含量不同，使得调节段2和基础段1两者的传热速率不同。
介质的总横截面积是指以垂直于轴向的平面为横截面，所有介质的投影的总面积。调节段2和基础段1两者的介质的总横截面积不同，由于热量沿径向传导，调节段2和基础段1两者的受热面积不同，使得调节段2和基础段1两者的传热速率不同。
本申请实施例中，来自加热面的热量沿径向在基础段1和调节段2之间传递，由于调节段2和基础段1两者的至少一个参数不同，参数包括导热率、质量、介质的壁厚H以及介质的总横截面积，因此，基础段1和调节段2两者的传热速率不同，使得热量从加热面沿径向的传热速率发生变化，在加热过程中，不会过快加热气溶胶生成基质10沿径向远离加热面的冷端区域，使得抽吸过程中气溶胶释放速率趋于一致，从而保证气溶胶生成基质10在抽吸前段和后段所释放的气溶胶较为一致，提高气溶胶释放一致性，保证抽吸体验前后一致的效果。
需要说明的是，抽吸的前段是指气溶胶生成基质10初始使用的时段，抽吸的后段是指气溶胶生成基质10接近气溶胶释放完全的时段。抽吸的前段和后段分别是指气溶胶生成基质10的使用生命周期内的前期和后期。
基于热阻公式，径向传热热阻＝介质沿径向的尺寸/(导热率*介质的总横截面积)，对于周圈加热和中心加热这两种加热方式，热量沿径向传递，采用本申请实施例提供的气溶胶生成基质10，可在完整的抽吸过程中(即气溶胶生成基质10的使用生命周期内)，控制传热速率，不会过快加热气 溶胶生成基质10的冷端部分，实现整体的释放速率一致性。
需要说明的是，基础段1和调节段2之间可能具有明显的物理界限。例如，基础段1和调节段2两者的材质、介质的壁厚以及介质的总横截面积不同的情况下，基础段1和调节段2之间可能具有明显的物理界限。基础段1和调节段2两者质量不同且具有空气间隔空间，两者也具有明显的物理界限。
基础段1和调节段2之间也可能没有明显的物理界限。示例性的，基础段1和调节段2两者可能仅仅是质量不同的情况下，如果基础段1和调节段2连接成整体，基础段1和调节段2可能没有明显的物理界限。但是并不影响基础段1和调节段2的划分，例如可以通过基础段1和调节段2两者的结构形状进行划分。
请参阅图10和图11，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10和功能段20。

气溶胶生成制品用于供用户吸食气溶胶生成基质10产生的气溶胶。例如用户可以通过过滤段21抽吸过滤后的气溶胶。气溶胶生成基质10产生的气溶胶在抽吸负压作用下输送到过滤段21。
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，加热件朝向加热面。加热件用于加热气溶胶生成基质10以产生气溶胶。也就是说，加热件的热量传递给加热面，再在气溶胶生成基质10中沿径向传递。
需要说明的是，本申请实施例中，气溶胶生成基质10用于加热产生气 溶胶。示例性的，气溶胶生成基质10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10被加热至着火点以下以产生气溶胶。气溶胶生成基质10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10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10更多的应用于加热不燃烧的方式产生气溶胶。
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，加热件可以与加热面接触或不接触。热对流的形式传递热量是指加热件不与加热面接触，加热件先对空气进行加热，然后热空气对气溶胶生成基质10进行烘烤加热。热传导是指加热件与加热面接触并将热量传导至气溶胶生成基质10。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10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10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10进行加热。

相较于现有技术中的造纸法、稠浆法等生产的有序、无序的丝状介质而言，挤压成型的介质相互连接，介质内的空气较少，能够提高气溶胶生成基质10的整体的热导率。而通过不同的参数可以有效调节气溶胶生成基质10不同部位的传热效率，从而提高抽吸一致性。
挤出成型是指物料通过挤出装置的料筒和螺杆间的作用，被螺杆向前推送，通过料筒的出料口的口模制成气溶胶生成基质10的一种加工方法。
气溶胶生成基质10的横截面的轮廓形状不限，示例性的，气溶胶生成 基质10的横截面的轮廓形状为圆形(请参阅图1)、椭圆形、多边形(包括但不限于三角形、正方形或者棱形等)、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。气溶胶生成基质10的横截面形状为异形以外的其他规则形状，产品一致性好，便于监控产品质量。
需要理解的是，气溶胶生成基质10的横截面的轮廓形状是指气溶胶生成基质10的横截面的最外边缘线的形状。例如，气溶胶生成基质10的横截面的轮廓形状是指基础段1和调节段2共同构成的横截面的最外边缘线的形状。
需要说明的是，轴向是气溶胶生成基质10的延伸方向。例如，气溶胶生成基质10采用挤出成型，轴向是气溶胶生成基质10挤出过程中的延伸方向。径向与轴向垂直，外是指沿径向远离中心区的方向，内与外相反。
请参阅图1，气溶胶生成基质10的横截面的轮廓形状为圆形。本申请实施例以气溶胶生成基质10的的横截面的轮廓形状为圆形为例进行举例说明，即气溶胶生成基质10整体为圆柱体。气溶胶生成基质10的轴向的尺寸大于其横截面上两点之间的最大距离例如直径。
可以理解的是，如果气溶胶生成基质10的横截面的轮廓形状为圆形，气溶胶生成基质10整体为棱柱体。
一实施例中，请参阅图1至图9，调节段2形成有贯穿其沿轴向的至少一端的第一气道2a。例如，第一气道2a贯穿调节段2沿轴向的一端。又例如，第一气道2a贯穿调节段2沿轴向的两端。气流可以从调节段2的一端沿轴向流动至调节段2的另一端。如此，第一气道2a能够汇集和流通气溶胶，畅通了气溶胶的释放路径，因此，可以提高气溶胶的提取效率。第一气道2a贯穿调节段2沿轴向的两端，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4至图9，基础段1形成有贯穿其沿轴向的至少一端的第二气道1b。例如，第二气道1b贯穿基础段1沿轴向的一端。又例如，第二气道1b贯穿基础段1沿轴向的两端。气流可以从基础段1的一端沿轴向流动至基础段1的另一端。如此，第二气道1b能够汇集和流通气溶胶，畅通了气溶胶的释放路径，因此，可以提高气溶胶的提取效率。第二气道1b贯穿基础段1沿轴向的两端，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。
第二气道1b的数量不限，例如，第二气道1b可以为一个或者多个。
一实施例中，请参阅图1至图9，第一气道2a和/或第二气道1b为沿直线延伸的直线形气道。直线形气道易于成形，能够降低制造难度。直线形气道内气流的流动阻力相对较小。
一实施例中，第一气道2a和/或第二气道1b为曲线形气道，曲线形气道的至少部分孔段呈曲率不为的曲线形。曲线形气道能够在不显著增加轴向长度的情况下，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，曲线形气道呈螺旋线形。也就是说，曲线形气道的立体形状呈空间螺旋线形。螺旋线形的曲线形气道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可以极大地延长气流的流动路径，将气溶胶从介质析出至曲线形气道中，提高气溶胶在调节段2内或者基础段1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。
需要说明的是，调节段2的内部和基础段1的内部均可能存在微孔， 比如，对于颗粒结合体的气溶胶生成基质10，颗粒与颗粒之间的间隙构成微孔。但是，本申请所述的第一气道2a和第二气道1b均与微孔不同，本申请所述的第一气道2a和第二气道1b属于宏观意义上的孔，微孔属于微观意义上的孔，第一气道2a和第二气道1b两者的横截面积以及长度等尺寸均比微孔大的多。第一气道2a和第二气道1b主要依靠设计的模具例如口模加工而成，因此，第一气道2a和第二气道1b两者的横截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，用于成型气溶胶生成基质10的物料为颗粒状物料，物料挤出成型的气溶胶生成基质10具有微孔，微孔的横截面积以及长度等尺寸通过挤出工艺及原料组份自然形成，物料加挤压流出模口后产生一定膨胀可以形成微孔。
一实施例中，请参阅图4和图5，基础段1形成有环形的放置空间，调节段2位于放置空间内，调节段2沿径向的内外两侧均与基础段1连接，基础段1沿径向的内表面或者外表面为加热面。也就是说，热量传递过程是：基础段1具有加热面的部分沿径向传递至调节段2再传递至基础段1的冷端部分。由于调节段2和基础段1的参数不同，因此，调节段2可以调节基础段1具有加热面的部分至基础段1的冷端部分的传热速率，从而使得加热过程中气溶胶释放速率趋于一致。
基础段1沿径向的内表面或者外表面为加热面。示例性的，一些实施例中，基础段1沿径向的内表面为加热面。可以是基础段1的中心区形成有加热口，加热件的至少部分位于加热口内，加热口的周向面即为基础段1沿径向的内表面，也就是加热面。另一些实施例中，基础段1沿径向的外表面为加热面。可以是加热件环绕于基础段1的外表面的周围。也就是说，加热件可以呈套设于基础段1外周的筒状结构。
示例性的，一实施例中，请参阅图4和图5，调节段2的介质均沿径向 延伸并连接放置空间沿径向的两个周向面。
一些实施例中，第一气道2a的横截面形状不限，示例性的，第一气道2a的横截面形状可以是圆形、多边形(包括但不限于三角形、正方形或者棱形等)、椭圆形、跑道形、扇形或异形等，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。
一实施例中，请参阅图4，调节段2的介质的壁厚H2小于基础段1的介质的壁厚H1。由于调节段2的介质的壁厚H2小于基础段1的介质的壁厚H1，调节段2用于传导热量的介质的壁厚H2更小，调节段2的传热速率低于基础段1的传热速率，使得基础段1具有加热面的部分向基础段1的冷端部分的传热效率降低，抽吸过程中气溶胶的释放一致性好。
一实施例中，请参阅图4，调节段2包括12个四方形的第一气道2a和4个扇形的第一气道2a，12个四方形的第一气道2a和4个扇形的第一气道2a沿周向均分分布。可以通过调节围设形成第一气道2a的介质的壁厚H2来调节传热效率。
需要理解的是，介质的壁厚可以是指围设形成第一气道2a或者第二气道1b的介质的壁厚。
一实施例中，请参阅图4和图5，基础段1包括外环部11和中心部12，外环部11环绕于中心部12的外周，以共同限定出放置空间，中心部12的介质的壁厚为0.2mm至0.25mm。示例性的，中心部12的介质的壁厚为0.2mm、0.21mm、0.22mm、0.23mm、0.24mm或者0.25mm等等。示例性的，调节段2的介质均沿径向延伸并连接外环部11和中心部12。由于用于构成气溶胶生成基质10的物料为固液混合物，具有粘滞性，容易与模具例如口模发生粘连，如果中心部12的介质的壁厚小于0.2mm或者大于0.25mm，气溶胶生成基质10的制造工艺例如挤出工艺复杂，外环部11、中心部12和调节段2三者难以挤出成型，良品率低。
一实施例中，基础段1的介质的总横截面积大于调节段2的介质的总横截面积。示例性的，基础段1包括外环部11和中心部12，外环部11环绕于中心部12的外周，以共同限定出放置空间，调节段2的介质均沿径向延伸并连接外环部11和中心部12，外环部11的介质的总横截面积和中心部12的介质的总横截面积之和大于调节段2的介质的总横截面积。
该实施例中，调节段2的受热面积小于基础段1的受热面积，调节段2的介质用于热传导的介质构成的传热通道相对较少，调节段2的传热速率低于基础段1的传热速率，使得基础段1具有加热面的部分向基础段1的冷端部分的传热效率降低，抽吸过程中气溶胶的释放一致性好。
一实施例中，请参阅图5，调节段2包括8个长方形的第一气道2a和4个扇形的第一气道2a，8个长方形的第一气道2a和4个扇形的第一气道2a沿周向均分分布。通过增大第一气道2a的横截面积，以减少围设形成第一气道2a的介质的数量，也就是说，减少调节段2中热传导的路径的个数，从而减少调节段2的介质的总横截面积。
一实施例中，基础段1的质量大于调节段2的质量。也就是说，调节段2用于传热的介质质量相对基础段1的介质质量少，调节段2的传热速率低于基础段1的传热速率，使得基础段1具有加热面的部分向基础段1的冷端部分的传热效率降低，抽吸过程中气溶胶的释放一致性好。
一实施例中，调节段2的导热率小于基础段1的导热率。导热率越小导热效率越低，调节段2的导热率相对更小，调节段2的传热速率低于基础段1的传热速率，使得基础段1具有加热面的部分向基础段1的冷端部分的传热效率降低，抽吸过程中气溶胶的释放一致性好。
一实施例中，请参阅图1至图3、以及图6至图9，基础段1环绕于调节段2的外周，调节段2沿径向的内表面为加热面或者基础段1沿径向的外表面为加热面。示例性的，一些实施例中，调节段2的中心区形成有安 装口，加热件的至少部分位于安装口内，安装口的周向面即为调节段2沿径向的内表面，也就是加热面。另一些实施例中，基础段1沿径向的外表面为加热面。可以是加热件环绕于基础段1的外表面的周围。也就是说，加热件可以呈套设于基础段1外周的筒状结构。
一实施例中，请参阅图1，基础段1为环形结构，基础段1沿径向的两个侧面的距离L为0.2mm至1mm。示例性的，基础段1沿径向的两个侧面的距离L为0.2mm、0.3mm、0.4mm、0.5mm、0.7mm、0.9mm或者1mm等等。一方面，热量通过基础段1沿径向传导，基础段1沿径向的两个侧面的距离L为上述尺寸，热量的沿径向传导的路径较长，能够有效延长热量在基础段1上的传导时长，从而降低热量在基础段1和调节段2之间的传热效率，抽吸过程中气溶胶的释放一致性好。另一方面，基础段1和调节段2均采用挤出成型，构成基础段1和调节段2的物料呈固液混合物，具有粘滞性，基础段1沿径向的两个侧面的距离小于0.2mm或者大于1mm，挤出工艺复杂，物料容易与模具例如口模发生粘连，难以挤出成型，良品率低。
一些实施例中，请参阅图1，基础段1没有第二气道1b。也就是说，第二气道1b的数量为零。基础段1沿径向的两个侧面均为连续的面。需要理解的是，基础段1在没有第二气道1b的基础上，可以有微孔。

一实施例中，请参阅图2和图3，基础段1形成有隔断槽1a，隔断槽1a沿径向贯通基础段1沿径向的两个侧面。也就是说，基础段1沿径向的两个侧面均是非连续的面。隔断槽1a可以减少基础段1的总横截面积，基础段1接收的热量减少，从而降低热量在基础段1和调节段2之间的传热效率，抽吸过程中气溶胶的释放一致性好。
一些实施例中，隔断槽1a可以为一个。另一些实施例中，隔断槽1a 可以为多个，多个隔断槽1a沿周向间隔分布。例如，多个隔断槽1a沿周向间隔均匀分布。
一实施例中，请参阅图9，基础段1的导热率小于调节段2的导热率。基础段1环绕于调节段2的外周，基础段1的导热率越小，基础段1单位时间传导的热量越少，降低热量在基础段1和调节段2之间的传热效率，抽吸过程中气溶胶的释放一致性好。
一实施例中，请参阅图6至图8，基础段1和调节段2之间形成有隔离两者的空气间隔空间10a。也就是说，基础段1套设于调节段2的外周，基础段1沿径向的内周面与调节段2沿径向的外周面之间间隔形成空气间隔空间10a。也就是说，基础段1和调节段2不接触。空气为热的不良导体，基础段1和调节段2之间通过空气间隔空间10a隔离，从而降低基础段1和调节段2之间的传热效率，抽吸过程中气溶胶的释放一致性好。
另一些实施例中，请参阅图4、图5和图9，基础段1和调节段2连接。示例性的，调节段2沿径向延伸的介质与基础段1连接。
一些实施例中，功能段20可以只设置过滤段21。
