雾化面25与收容腔33的内壁面配合形成雾化腔4，在一实施例中，下座体32的底壁321作为雾化腔4的底壁321。雾化腔4具有进气通道41和出气通道42。雾化腔4通过出气通道42与导气通道13连通。进气通道41包括间隔设置的第一进气通道411和第二进气通道412，第一进气通道411和第二进气通道412与雾化腔4连通。第一进气通道411的气流从雾化芯2的雾化面25靠近第一进气通道411的一端传输至远离第一进气通道411的另一端，以通过第一进气通道411的气流携带雾化面25产生的气溶胶传输至雾化腔4的出气通道42。其中，第二进气通道412设置于下座体32的底壁321上。
其中，依次连通的进气通道41、雾化腔4、出气通道42和导气通道13构成气流通道5，进气通道41作为气流通道5的进气端51，导气通道13远离出气通道42的一端作为气流通道5的出气端52。
请参阅图3，雾化芯2可以包括第一端21和第二端22，雾化芯2的第一端21与雾化芯2的第二端22相对设置。第一进气通道411靠近雾化芯2的第一端21设置，第一进气通道411的气流先到达雾化芯2的第一端21再自雾化芯2的第一端21传输至第二端22，以将雾化芯2的雾化面25产生的气溶胶传输至雾化腔4的出气通道42，然后与第二进气通道412的气流混合后从出气通道42流出雾化腔4。第二进气通道412的气流在气流通道5的内侧面与气溶胶之间形成阻隔层，以阻挡第一进气通道411的气流携带的气溶胶与气流通道5的内侧面接触，避免气溶胶接触气流通道5的内侧壁冷凝、气溶胶中携带的液滴被气流通道5的内壁面捕获，进而提升气流通道5中气溶胶的传输效率。
请参阅图5-6，图5是本申请提供的雾化器中第一种实施例的结构简图；图6是本申请提供的雾化器中第二种实施例的结构简图。
为了进一步提高气流通道5中气溶胶的传输效率，第二进气通道412的气流流速大于第一进气通道411的气流流速，可以进一步的阻隔第一进气通道411的气流携带的气溶胶与气流通道5的内壁面接触。例如，第二进气通道412的气流流速为第一进气通道411的气流流速的1.2-1.5倍，如果第二进气通道412的气流流速过大，用户吸食的气溶胶浓度太低，如果第二进气通道412的气流流速过小，难以起到有效阻隔第一进气通道411的气流携带的气溶胶与气流通道5的内壁面接触。在一实施例中，第一进气通道411的横截面积大于第二进气通道412的横截面积，进而使得在用户的相同抽吸压差下第二进气通道412的气流流速大于第一进气通道411的气流流速。在其它可选实施例中，当第一进气通道411的横截面的面积等于第二进气通道412的横截面积时，在第二进气通道412远离雾化腔4的一侧或第二进气通道412的内部形成增压 结构，以使第二进气通道412的气流流速大于第一进气通道411的气流流速。例如，第二进气通道412的纵截面为缩口结构。即第二进气通道412靠近雾化腔4的端口小于第二进气通道412远离雾化腔4的端口。其中，第二进气通道412的纵截面为直角梯形或等腰梯形，第二进气通道412的进气方向与气流通道5的内壁面形成10-30度夹角，进一步加强阻隔效果。
其中，雾化芯2的雾化面25与气流通道5的内侧面可以呈预设角度设置。雾化芯2的雾化面25与气流通道5的内侧面所呈的预设角度不同，第一进气通道411和第二进气通道412的设置方式可以根据雾化芯2的雾化面25朝向调整。

第一进气通道411和第二进气通道412具有公共侧壁，公共侧壁靠近雾化芯2的端部设有延伸部4171，延伸部4171具有导气部417，导气部417用于将第一进气通道411的气流导流至 雾化面25。在本实施例中，公共侧壁为分隔部416。其中，延伸部4171朝向雾化面25的表面具有倒角4172，倒角4172作为导气部417。
第二进气通道412设置于第一进气通道411和雾化腔4的内侧面之间，以使第二进气通道412形成的气流在第一进气通道411携带的气溶胶与雾化腔4的内侧面之间形成阻隔层，以避免第一进气通道411携带的气溶胶与雾化腔4的内侧壁接触，进而提升气溶胶的传输效率。本实施例中，分隔部416的顶面与凸起部415的顶面平齐，分隔部416的底面与凸起部415的底面可以平齐，分隔部416的底面也可以高于或低于凸起部415的底面。
请参阅图17和18，在另一实施例中，为了避免第一进气通道411的气流扩散，使第一进气通道411中的气流更多的携带气溶胶，则在第一进气通道411的靠近雾化面25的一端形成导气部417，以使第一进气通道411的气流更多的流向雾化芯2的第一端21。在一具体实施例中，分隔部416靠近雾化芯2的端部设置有延伸部4171，即分隔部416的顶部延伸出凸起部415之外。延伸部4171具有导气部417，导气部417用于将第一进气通道411的气流导流至雾化面25。延伸部4171靠近雾化面25的表面具有倒角4172，倒角4172和延伸部4171朝向雾化面25的一侧配合形成导气部417。其中，倒角4172低于雾化面25的雾化区251，以将从第一进气通道411进入的气流引向雾化面25的雾化区251远离出气通道42的一侧。也就是说，导气部417在雾化面25上的投影区域处于非雾化区251和/或雾化芯2的第一端21与底壁321之间的第一密封件6朝向雾化腔4的表面。
在一实施例中，倒角4172为凸块，凸块的纵截面为直角梯形，凸块与雾化腔4的出气通道42相对和相背的表面均为平面，且凸块与雾化腔4的出气通道42相对表面的面积大于凸块与雾化腔4的出气通道42相背表面的面积。凸块朝向第二进气通道412的表面也为平面，且与分隔部416朝向第二进气通道412的表面处于同一平面，凸块朝向雾化芯2的表面为斜面，且斜面靠近出气通道42的一端比斜面的另一端更靠近雾化芯2。通过设置延伸部4171可以避免第二进气通道412的气流在雾化腔4内扩散，进而使得形成的阻隔层可以更好的阻隔气溶胶与雾化面25的内侧壁接触，进一步提升气流通道5的气溶胶的传输效率。
在一可选实施例中安装座3靠近出气通道42的一端通过第一密封件6与壳体1的出气部连通。第一密封件6上具有通孔61，沿靠近雾化腔4的端部到远离雾化腔4的端部，通孔61的横截面逐渐减小，且通孔61靠近雾化腔4端面的尺寸不小于雾化腔4横截面的尺寸，通孔61远离雾化腔4端面的尺寸与壳体1上作为出气部的出气口的尺寸相同，避免第一气流通道5的气流携带的气溶胶撞击出气口，进而提升气流通道5的气溶胶的传输效率。
本实施中将雾化芯2的雾化面25与气流通道5的内侧面平行设置，通过第一进气通道411中的气流携带雾化芯2的雾化面25产生的气溶胶；通过设置第二进气通道412，使第二进气通道412中的气流在第一进气通道411的气流携带的气溶胶与气流通道5的内壁面之间形成阻隔层，阻隔层阻挡第一进气通道411的气流携带的气溶胶撞击气流通道5的内壁面，避免气溶胶在气流通道5的内壁面上发生凝结、携带的液滴被气流通道5的内壁面捕获，进而提升气流通道5内气溶胶的传输效率。
