具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
方位限定：以附图中显示的上、下、顶、底方位为发明的上、下、顶、底。需要理解的是，“上”、“下”等指示的方位或位置关系为基于附图所示的方位或位置关系、以特定的方位构造和操作，仅是为了便于描述本技术方案，而不是指示所指的装置或元件必须具有特定的方位，因此不能理解为对本发明的限制。
图1是本发明一实施例中电子雾化装置的结构示意。请参照图1，电子雾化装置100包括固态气溶胶生成基质料筒1、壳体2、液体雾化单元3、电源4和电路控制板5。液体雾化单元3包括储液腔31、加热体32和气流通道8。加热体32与储液腔31导液连接，用于加热雾化液体。雾化的气体从液体雾化单元3的气流出口83流出，经过空腔81，到达并穿过装有固态气溶胶生成基质的料筒1。
图2是固态气溶胶生成基质料筒的结构及气体流动示意图。请参考图2，料筒1包括多个独立的收容单元11a-e，用于收容固态气溶胶生成基质，每个独立的收容单元11a-e形成一个子气流通道。每一收容单元具有一个承托部111，用于承托固态气溶胶生成基质，例如烟草。承托部111为网状或者开设 有至少一通气孔，以供下面加热体6加热雾化的气体穿过。各承托部111在电子雾化器纵向方向上的位置并不全相同，气流出口83到达各承托部111的距离不同。
请参考图3-a，料筒1的底部12可以为相对料筒1中轴线倾斜的平板，而承托部111a-e为底部12的一部分，承托部111a-e相对料筒1中轴线依次升高。图3-a的收容单元11a-e宽度一致，容置的烟草的量(体积或质量)相对料筒1中轴线依次增多。收容单元11a-e的阻档气流通过的力依次增大，因此从液体雾化单元3出来的雾化气首先选择阻力小的通道收容单元11a通过。雾化气在通过收容单元11a的时候，部分会冷凝成液滴被烟草吸收，而烟草吸收液体后会增加气体流动的阻力，直至不能通过气流。随着收容单元11a的阻力增大，从液体雾化单元3出来的雾化气逐渐增加通过收容单元11b的气流量。同理，当前面的收容单元11通气一段时间后，阻力增加，液体雾化单元3出来的雾化气选择下一个阻力小的收容单元11通过。
请参考图3-b，料筒1的底部12为阶梯状，承托部111a-e垂直于料筒1的中轴线并依次阶梯升高。同样，图3-b的收容单元11a-e宽度一致，容置的烟草的量(体积或质量)相对料筒1中轴线依次增多。当前面的收容单元11通气一段时间后，阻力增加，液体雾化单元3出来的雾化气选择下一个阻力小的收容单元11通过。
请参考图3-c，料筒1的底部12相对料筒1的中轴线对称设置，呈中部低，二侧高的趋势。底部12为阶梯状，收容单元11a-c宽度一致，容置的烟草的量(体积或质量)依次增多。也就是，中间的11a离液体雾化单元3的气流出口83最近，而且烟草的量最少，所以阻力最小。气流出口83出来的雾化气选择阻力小的收容单元11a通过，在收容单元11a的烟草吸收冷凝液增加 阻力后，又依次选择11b、11c通过。
图3-d的料筒1与图3-c不同之处在于底部12大致呈
Figure PCTCN2020123929-appb-000001
型。
图3a-d所示料筒1的实施例，通过设置多个独立的收容单元11a-e，通过设置承托部111a-e到气流出口83的距离、烟草9的量来形成不同的气流阻力，从而气流出口83出来的雾化气依次选择阻力小的收容单元11a-e通过，使抽吸味道更均匀一致。
在图3a-d所示的实施例是通过相同宽度的收容单元11容置不同烟草9的量，形成不同高度的烟草9，形成烟草9底部不同的阻力。为了形成烟草9底部不同的阻力，还可以将收容单元11a-e的宽度设置成不同，收容相同量(体积或质量)的烟草。如图4a-c，收容单元11a-e的宽度不同，相同量的烟草9高度不同，使气体通过收容单元11a-e的阻力不同。
收容单元11a-e的收容腔横截面可以为各种形状，可以是平行四边形(如图5-a)，也可以是圆形(如图5-b)，也可以是扇形(如图5-c)。料筒的外形轮廓也可以是多种形状，例如长方形、圆形等。
请参考图6，本发明还提供在收容单元11a-e的底部设有不同阻力的气流阻力片的使料筒不同的收容单元11a-e的气流阻力不同的实施方式。图6的料筒1的底部12为网状片，不同的收容单元11a-e的底部设有不同阻力的气流阻力片，根据需要调整气流阻力片的厚度或者是空隙率来调整阻力的大小。可以理解，在收容单元11a-e的底部设有不同阻力的气流阻力片同样试用于图3a-d和图4a-c的各个实施例。
请参考图7a-c，本发明还提供通过依次加热控制不同收容单元11a-e的温度来获得不同的阻力。图7a所示，每一收容单元11a-e的二侧均设有加热件，形成独立的加热电路14a-e。抽吸时，控制电路控制加热电路14a-e依次加热， 加热的收容单元11因气流加快，降低了气流阻力，因此气流出口83出来的雾化气选择阻力小的被加热的收容单元11通过，直至加热结束。图7b所示，收容单元11a-e为单侧加热，形成独立的加热电路14a-d，控制电路控制加热电路14a-d依次加热。
料筒的基体可以一体注塑成型，料筒基体具有多个隔板和多个承托部，形成上述实施例的收容单元11a-e。
可以理解的，以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，可以对上述技术特点进行自由组合，还可以做出若干变形和改进，这些都属于本发明的保护范围；因此，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
