吸液体12在一些实施例中可以由多孔陶瓷、多孔玻璃陶瓷、多孔玻璃等硬质多孔材料烧结而成。优选地，吸液体12由多孔陶瓷或多孔陶瓷与金属的组合物制成。在一些实施例中，多孔陶瓷上的微孔的孔径范围可为1μm至100μm。多孔陶瓷的平均孔径可为10-35μm。优选地，多孔陶瓷的平均孔径为20-25μm。
多孔陶瓷的孔隙率可为40%-85%，孔隙率是指多孔基质内的微小空隙的总体积与该多孔基质的总体积的比值。孔隙率的大小可以根据液态基质的成分来调整，例如对于粘度较高的液态基质，孔隙率则可以高一些，以保证导液效果。优选地，对于高粘度液态基质，多孔陶瓷的孔隙率可以为60-85%。
图4-6示出了本发明第一实施例中的吸液体12，该吸液体12可大致呈长方体状，其包括一个用于安装发热体11的呈纵长型的雾化面122以及用于导入液态基质的吸液面121。吸液面121朝向储液腔3并与储液腔3导液连通，以让储液腔3中存储的液态基质进入到吸液体12中。液态基质在吸液体12中受热雾化后，再经由雾化面122逸出。该吸液体12在一些实施例中还可包括设置于吸液面121上的凹凸结构，以增加吸液体12与液态基质之间的接触面积。可以理解地，在其他实施例中，吸液体12的横截面也可以呈圆形、椭圆形、梯形、三角形、多边形等其他形状。
吸液体12在一些实施例中可呈阶梯状，其包括靠近雾化面122的第一层125和远离雾化面122的第二层126。第一层125、第二层126均可大致呈长方体状，且第一层125的外部尺寸小于第二层126的外部尺寸。在本实施例中，第一层125的长度小于第二层126的长度，第一层125的宽度与第二层126的宽度相当。该吸液体12设置呈阶梯状，可方便吸液体12的安装。
第一层125远离第二层126的一侧面形成平坦的长方形雾化面122。在一些实施例中，第二层126远离第一层125的一侧表面朝向雾化面122凹陷形成有一导液槽123，使得吸液体12整体呈碗型。一方面，导液槽123的内表面也形成吸液面121，从而可增加吸液面121的面积；另一方面，可保证吸液面121到雾化面122的距离足够近，提高导液性能。可以理解地，导液槽123的数量并不局限于一个，其也可以为两个或两个以上。
该导液槽123的横截面形状可与吸液体12的横截面形状相匹配。在本实施例中，导液槽123的横截面呈长方形，且导液槽123、第一层125、第二层126、发热体11的中轴线重合。在一些实施例中，该导液槽123的横截面尺寸（长度和宽度尺寸）可由远离雾化面122的一侧向靠近雾化面122的一侧逐渐减小。导液槽123具有一与雾化面122平行的槽底面1230，该凹凸结构可设置于槽底面1230上。由于一些高粘度的液态基质在加热后粘度会降低，流动性会变好。而相对来说，槽底面1230与雾化面122的距离更近，本发明通过将凹凸结构设置于槽底面1230上，可增加槽底与液态基质之间的换热面积，更方便将发热体11的热量快速地传导给液态基质，提高液态基质的流动性，防止干烧的发生。此外，由于导液槽123槽底的液态基质的体积相对较小，而该部分液态基质是即将流向雾化面122被加热雾化的液态基质，通过将凹凸结构设置于槽底面1230上，还可增加槽底的吸液面积，提高热量利用效率，避免热量浪费。可以理解地，在其他实施例中，当吸液体12采用侧面进液的方式时，导液槽123相应地开设于吸液体12的侧面，该凹凸结构设置于导液槽123朝向雾化面122的一侧面上。在另一些实施例中，当吸液体12为片状吸液体时，其吸液面为平面，该凹凸结构设置于该平面吸液面上。
该凹凸结构的底部与槽底面1230相接，顶部伸向液态基质。在一些实施例中，槽底面1230（即该凹凸结构的底部）与雾化面122之间的距离（垂直距离）h3在4mm以内，以保证有充足的热量传导至该凹凸结构处，进而传导给液态基质。槽底面1230到雾化面122之间的距离h3在1mm以上，以避免漏液，并保证吸液体12具有一定的强度。
该凹凸结构在一些实施例中可包括呈长条状的至少一个凸棱124，凸棱124的底部与槽底面1230相接，顶部伸向液态基质。通常，凸棱124的数量可以为2-10个。凸棱124的横截面形状可包括三角形、弧形（例如圆弧形、椭圆弧形）、多边形（例如梯形、方形、正多边形）中的至少一个。可以理解地，该凹凸结构的结构形状不受限制，例如该凹凸结构也可包括呈环状（例如圆环状、椭圆环状、方环状）的凸起或凹陷，或者其也可包括呈点阵状分布的凸起或凹陷。
在本实施例中，该凹凸结构包括呈等间距平行排列的八个长条状凸棱124。凸棱124的横截面呈等腰三角形状，该横截面的顶角角度α可以为10-60度。槽底面1230包括一长边，凸棱124与该长边的夹角β可以为0-90度，优选为60-90度。凸棱124的高度h1是导液槽123的深度h2的0.1-0.6倍，优选为0.4-0.6倍。相邻两个凸棱124之间的间距d1是凸棱124的横截面的底边长d2的0.2-0.3倍。
性能测试：采用丙三醇和1，2-丙二醇一比一质量比的混合液体作导液性能测试，其中，凸棱124的横截面为等腰三角形，该横截面的顶角角度α为10度，凸棱124与槽底面1230长边的夹角β为60度，槽底面1230与雾化面122之间的距离h3为2.05mm，导液槽123的深度h2为2.58mm，凸棱124的高度h1为1.45mm，槽底面1230和该八个凸棱124的表面积为14mm 2；测试结果：导液时间为30-50s，单口抽吸烟雾量为4.0-4.8mg/口。
图7-8示出了本发明第二实施例中的吸液体12，在本实施例中，吸液体12的凹凸结构包括呈等间距平行排列的十个长条状凸棱124。
性能测试：采用丙三醇和1，2-丙二醇一比一质量比的混合液体作导液性能测试，其中，凸棱124的横截面为等腰三角形，该横截面的顶角角度α为10度，凸棱124与槽底面1230长边的夹角β为90度，槽底面1230与雾化面122之间的距离h3为2.05mm，导液槽123的深度h2为2.58mm，凸棱124的高度h1为1.5mm，槽底面1230和该十个凸棱124的表面积为45mm 2；测试结果：导液时间为30-40s，单口抽吸烟雾量为5.0-6.0mg/口。
图9-10示出了本发明第三实施例中的吸液体12，在本实施例中，吸液体12的凹凸结构包括间隔平行设置的两个长条状凸棱124。
性能测试：采用丙三醇和1，2-丙二醇一比一质量比的混合液体作导液性能测试，其中，凸棱124的横截面为等腰三角形，该横截面的顶角角度α为40度，凸棱124与槽底面1230长边的夹角β为90度，槽底面1230与雾化面122之间的距离h3为2.05mm，导液槽123的深度h2为2.58mm，凸棱124的高度h1为1.45mm，槽底面1230和该两个凸棱124的表面积为10.8mm 2；测试结果：导液时间为55-70s，单口抽吸烟雾量为3.5-4.5mg/口。
图11-12示出了本发明第四实施例中的吸液体12，在本实施例中，吸液体12的凹凸结构仅包括一个长条状凸棱124。
性能测试：采用丙三醇和1，2-丙二醇一比一质量比的混合液体作导液性能测试，其中，凸棱124的横截面为等腰三角形，该横截面的顶角角度α为60度，横截面的底边长d2为1.45mm，凸棱124与槽底面1230长边的夹角β为90度，槽底面1230与雾化面122之间的距离h3为2.05mm，导液槽123的深度h2为2.58mm，凸棱124的高度h1为1.25mm，槽底面1230和该一个凸棱124的表面积为7.82mm 2；测试结果：导液时间为60-70s，单口抽吸烟雾量为3-4mg/口。
作为对比，图13示出了现有技术一些实施例中的吸液体12，该吸液体12的槽底面1230上未设置有凹凸结构。
性能测试：采用丙三醇和1，2-丙二醇一比一质量比的混合液体作导液性能测试，其中，槽底面1230与雾化面122之间的距离h3为2.05mm，导液槽123的深度h2为2.58mm，槽底面1230的表面积为4mm 2；测试结果：导液时间为70-80s，单口抽吸烟雾量为3-4mg/口。
由上述各性能测试的结果可以看出，随着凸棱124数量的增加，槽底面1230和该至少一个凸棱124的表面积大幅增加，导液时间显著减少，导液速度和单口抽吸烟雾量显著增加，雾化效果提高。
可以理解地，上述各技术特征可以任意组合使用而不受限制。
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。
