请一并参看图3、图6及图7，基座1501的顶部开设有出烟孔1501a，基 座1501的外壁面还构造有连通气道1507，连通气道1507连通于雾化腔150a与出烟孔1501a之间，使得雾化产生的烟雾能够在用户抽吸作用下由雾化腔150a流向出烟孔1501a，以供用户吸食。
请一并参看图3及图5，进一步地，回气通道150b的进气端I连通于连通气道1507与雾化腔150a连通的下端，而回气通道150b的出气端O与储液腔130连通，如此用户在抽吸过程中，气溶胶基质在雾化芯152的加热作用下被雾化后，烟雾经连通气道1507及出烟孔1501a流向用户口腔的过程中产生的部分冷凝液，能够在重力作用下由连通气道1507的管壁流向回气通道150b，并经回气通道150b被吸收并储存至储液腔130，防止用户抽吸到冷凝液，减少冷凝液在连通气道1507中流动产生的噪声，提高用户体验。
请重新参看图3及图4，进一步地，回气槽1505沿基座1501外壁面的周向迷宫式设置，迷宫式结构的设计能够有效防止储液腔130中的气溶胶形成基质通过回气通道150b泄漏至外界，提高用户体验。
雾化器10还包括电极17，电极17配接于底座11的底壁110上。雾化芯密封件154大体呈下端开口的中空筒状，雾化芯152的加热面以及电连接面通过雾化芯密封件154外露，并且电连接面与电极17电连接，电连接面用于向加热面提供电能，加热面用于产生雾化气溶胶形成基质所需的热量。在本具体实施例中，雾化芯152为多孔陶瓷芯结构。
请一并参看图3、图6及图8，进一步地，封液件1503的顶部开设有第一进液孔1503a，基座1501上开设有第二进液孔1501b，雾化芯密封件154上开设有第三进液孔154a。其中，第一进液孔1503a、第二进液孔1501b以及第三进液孔154a共同连通形成引流储液腔130内气溶胶形成基质流向雾化芯152的进液通道。在抽吸过程中，雾化芯152雾化由储液腔130提供的气溶胶形成基质，且雾化后形成的烟雾在进气口1101引入的气体的带动下输出至用户口腔供吸食。
请重新参看图3及图4，进一步地，雾化器10包括吸液件19，吸液件19设置于两个凸台1121之间且位于雾化组件15的下方，用于吸收由雾化组件 15滴落的冷凝液。
本实用新型雾化器10，固定座150上构造形成有回气通道150b，储液腔130内气溶胶形成基质在消耗后，可以通过回气通道150b补入外界空气，避免储液腔130内形成负压，以平衡储液腔130内的气压差，实现下液顺畅，进而保障雾化芯152的供液充足，防止雾化芯152干烧，提高气溶胶发生装置100的安全性能。
本实用新型还提供一种具有上述雾化器10的气溶胶发生装置100，因气溶胶发生装置100具有上述雾化器10的全部功能，在此不再赘述。
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱落本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。因此，本实用新型专利的保护范围应以所附权利要求为准。
