为实现上述目的，本发明采用的技术方案是：提供一种气溶胶发生装置， 包括上述任一方案提供的所述雾化器。
本发明实施例中的上述一个或多个技术方案，与现有技术相比，至少具有如下有益效果之一：
本发明实施例中的雾化器及气溶胶发生装置，雾化器结构中，通过在储液腔中设置多孔介质，多孔介质可吸附储液腔中的气溶胶形成基质，并可将吸附的气溶胶形成基质束缚于多孔介质中。在雾化器工作时，束缚于多孔介质中的气溶胶形成基质，可经由多孔介质缓慢均匀地传输至进液口，以减缓气溶胶形成基质经由进液口进入雾化腔中的流速，防止储液腔中的气溶胶形成基质进入雾化腔中的流速过快，从而有效降低漏液风险。并且，由于储液腔中的气溶胶形成基质需经由多孔介质传输至进液口，避免储液腔中的气溶胶形成基质直接通过进液口进入雾化腔中，在减缓气溶胶形成基质流速的同时，可达到均匀进液的效果，从而有利于提升雾化效果。而且，通过对多孔介质高度的限定，平衡多孔介质的储液量和导液能力。
