请一并参阅图1至图10，现对本实用新型实施例提供的雾化器进行说明。本实用新型实施例提供的雾化器适用于气溶胶发生装置，气溶胶发生装置可通过其电源装置5电驱动雾化器启动工作，则雾化器可将气溶胶形成基质雾化形成烟雾，以供用户吸食而达到模拟吸烟的效果。请结合参阅图1、图3和图4，本实用新型实施例提供的雾化器包括储液件1、底座组件2和雾化组件3，储液件1内部形成储液腔11，便可以通过储液腔11储存气溶胶形成基质。底座组件2装配于储液件1的底部，且底座组件2至少部分收容于储液件1内部，以使储液件1内部于底座组件2之外的部分界定出储液腔11。请结合参阅图4，底座组件2内部形成有雾化腔221，雾化组件3设置于雾化腔221内，雾化腔221与储液腔11连通，以使储液腔11内的气溶胶形成基质进入雾化腔221，供雾化腔221内的雾化组件3加热并雾化。可以理解地，请结合参阅图4和图10，雾化组件3包括在通电后发热的雾化芯31，雾化芯31设置于雾化腔221内，雾化芯31可以是但不限于具有吸液能力的多孔陶瓷雾化芯。底座组件2内部的雾化腔221与进气口211连通，则雾化腔221中雾化形成的烟雾，可在底座组 件2的进气口211引入的气体的带动下输出至用户口中，以供用户吸食。
请结合参阅图6、图8和图9，底座组件2上分别构造形成有储液空间8、回液流道9和回气支道4，储液空间8与雾化腔221连通，以使得储液空间8可对雾化腔221或导烟气道13内产生的冷凝液进行集中储存。回液流道9连通于储液空间8与储液腔11之间，且回气支道4连通于储液空间8与回液流道9之间，以在用户使用气溶胶发生装置的过程中，储液腔11内的气溶胶形成基质被消耗后，在储液腔11内产生的负压作用下，储液空间8中的冷凝液可通过回液流道9及回气支道4吸附至储液腔11内，达到平衡储液腔11内气压差的目的，从而避免储液腔11内形成负压而导致下液不畅。可以理解地，在储液空间8中的冷凝液或气溶胶形成基质较多时，当储液腔11内的气溶胶形成基质被消耗后，在储液腔11内产生的负压作用下，通过回液流道9及回气支道4主要向储液腔11补入冷凝液或气溶胶形成基质，以实现储液腔11内气压差的平衡。而在储液空间8中的冷凝液或气溶胶形成基质较少时，可以在回气支道4和/或回液流道9向储液腔11补入冷凝液或气溶胶形成基质的同时，还向储液腔11补入外部空气，以实现储液腔11内气压差的平衡。并且，在储液空间8与回液流道9之间设置回气支道4，可以通过回液流道9与回气支道4，从多角度、多部位对储液空间8中的冷凝液或气溶胶形成基质进行吸附，使得储液空间8中的冷凝液或气溶胶形成基质可被快速吸收至储液腔11中，一方面可快速平衡储液腔11内的压差，另一方面可增强冷凝液或气溶胶形成基质的吸附效果，避免用户抽吸到冷凝液而降低口感。
本实用新型实施例提供的雾化器，在底座组件2上分别构造形成有与雾化腔221连通的储液空间8、连通于储液空间8与储液腔11之间的回液流道9和连通于储液空间8与回液流道9之间的回气支道4。则在用户使用气溶胶发生装置的过程中，可以利用底座组件2上的储液空间8，对雾化腔221或导烟气道13内的冷凝液和/或气溶胶形成基质进行储存。随着储液腔11内的气溶胶形成基质被不断消耗，在储液腔11内产生的负压作用下，储液空间8中的冷凝液 和/或气溶胶形成基质，能够通过回液流道9及回气支道4吸附至储液腔11内，以达到平衡储液腔11内气压差的目的，避免储液腔11内形成负压而导致下液不畅。而在用户未使用气溶胶发生装置时，冷凝液和/或气溶胶形成基质保持在回液流道9中，即使从回液流道9滴落冷凝液和/或气溶胶形成基质，储液空间8对冷凝液和/或气溶胶形成基质进行储存，有效避免产生飞液和冷凝液泄露的现象，提升用户的体验感。
请结合参阅图3和图4，在其中一些实施例中，回液流道9包括分别设于底座组件2上的第一回液通道222和第二回液通道216。进一步参阅图5和图6，第一回液通道222的第一出液端口2222与储液腔11连通，第二回液通道216的第二出液端口2162与第一回液通道222的第一进液端口2221连通，第二回液通道216的第二进液端口2161与储液空间8连通，回气支道4的第三进液端口41分别与进气口211和储液空间8连通，回气支道4的第三出液端口42与第一回液通道222的第一进液端口2221连通。通过采用上述方案，在底座组件2上分别设置第一回液通道222和第二回液通道216，将第二回液通道216的第二出液端口2162与第一回液通道222的第一进液端口2221连通以构成回液流道9，并将回气支道4的第三出液端口42与第一进液端口2221连通。则储液腔11内产生的负压作用下，吸附储液空间8中的冷凝液和/或气溶胶形成基质的路径如下：其一，经第二回液通道216的第二进液端口2161进入第二回液通道216，再由第二回液通道216进入第一回液通道222，最后由第一回液通道222的第一出液端口2222进入储液腔11；其二，经回气支道4进入第一回液通道222，最后由第一回液通道222的第一出液端口2222进入储液腔11。这样，储液空间8中的冷凝液和/或气溶胶形成基质，能够分别通过回气支道4和第二回液通道216吸附至第一回液通道222，最终由第一回液通道222的第一出液端口2222进入储液腔11，以达到平衡储液腔11内气压差的目的，避免储液腔11内形成负压而导致下液不畅。可以理解地，第一回液通道222中主要存在的液体包括：因重力作用由储液腔11流入第一回液通道222的气溶胶形成基质、 空气带动由第二回液通道216流入第一回液通道222的冷凝液和/或气溶胶形成基质、空气带动由回气支道4流入第一回液通道222的冷凝液和/或气溶胶形成基质。上述液体中的大部分可被储液腔11内产生的负压快速吸附至储液腔11中，以达到平衡储液腔11内气压差的目的。而上述较少部分液体会沿着第一回液通道222内壁滴落至第二回液通道216中，第二回液通道216内吸收的冷凝液和/或气溶胶形成基质、来源于第一回液通道222的气溶胶形成基质和冷凝液，以及来源于回气支道4的气溶胶形成基质和/或冷凝液，最终由第二回液通道216的第二进液端口2161进入储液空间8，有效避免产生飞液和冷凝液泄露的现象，提升用户的体验感。第一回液通道222中的上述液体几乎不会进入回气支道4，是由于回气支道4为连通于第一回液通道222与储液空间8之间的狭长的气流通道，且回气支道4的流通截面积远小于第二回液通道216的流通截面积。在用户抽吸过程中，储液腔11内的气溶胶形成基质被消耗后，在储液腔11内产生的负压作用下，外界空气可从进气口211、回气支道4、第一回液通道222的路径补入储液腔11，同时储液空间8中的冷凝液和/或气溶胶形成基质也可以随空气气流从进气口211、回气支道4、第一回液通道222的路径补入储液腔11，以辅助平衡储液腔11内气压差的平衡，避免储液腔11内形成负压而导致下液不畅。
请结合参阅图5、图6和图7，在其中一些实施例中，底座组件2上还设有连通于第一回液通道222的第一进液端口2221与第二回液通道216的第二出液端口2162之间的缓冲腔7，第一回液通道222的第一出液端口2222的设置高度高于第一回液通道222的第一进液端口2221的设置高度，第二回液通道216位于第一回液通道222的第一进液端口2221的下方，回气支道4的第三出液端口42与缓冲腔7连通。通过采用上述结构设置，在位于底座组件2上部的第一回液通道222与位于底座组件2下部的第二回液通道216中间增设缓冲腔7，有利于第一回液通道222中滴落的气溶胶形成基质和冷凝液，首先在缓冲腔7中短暂集聚，然后在重力的作用下，通过经过第二回液通道216快速流入储液 空间8，这样进一步避免第一回液通道222中滴落的气溶胶形成基质和冷凝液进入回气支道4。请结合参阅图5和图6，在其中一些实施例中，第一回液通道222的第一进液端口2221与第二回液通道216的第二出液端口2162错开设置，则由第一回液通道222的第一进液端口2221滴落的气溶胶形成基质和冷凝液，不会直接由第二回液通道216的第二出液端口2162回流至第二回液通道216内，而是先在缓冲腔7中短暂缓冲集聚后，接着在重力的作用下，通过经过第二回液通道216快速流入储液空间8。可以理解地，储液空间8可以是设于烟弹座21和/或基座223上的储液槽或储液仓，也可以是构造形成于烟弹座21和/或基座223内部的储液室。
请结合参阅图4、图8和图10，在其中一些实施例中，底座组件2包括装配于储液件1底部的烟弹座21和收容于储液件1内部的固定座22，固定座22设置于烟弹座21上，烟弹座21上开设有连通外界空气的进气口211，可以通过进气口211引入外部空气。固定座22内部形成有雾化腔221，雾化组件3设置于雾化腔221内，雾化腔221与储液腔11连通，以使储液腔11内的气溶胶形成基质进入雾化腔221，供雾化腔221内的雾化组件3加热并雾化。请结合参阅图3、图4和图8，在其中一些具体实施例中，固定座22包括支撑于烟弹座21上的基座223和套设于基座223上的封液件224，基座223具有构造形成雾化腔221的内腔，以使雾化腔221构造形成于固定座22内部。基座223的外侧壁上开设有第一回液槽225，封液件224的内侧壁与第一回液槽225围合形成第一回液通道222。当然，可以理解地，也可以在基座223上设置雾化槽，在封液件224套设于基座223上后，封液件224与雾化槽围合形成雾化腔221，以使雾化腔221构造形成于固定座22内部。也可以直接在基座223的侧壁上直接开设第一回液通道222，还可以在封液件224上直接开设第二回液通道216。请结合参阅图3、图4和图8，在其中一些具体实施例中，在烟弹座21的外侧壁上开设有第二回液槽215，将储液件1套设于烟弹座21的外侧，使得储液件1的内侧壁与第二回液槽215围合形成第二回液通道216。当然，可以理解地， 也可以直接在烟弹座21的侧壁上直接开设第二回液通道216，还可以在储液件1上直接开设第二回液通道216。
请结合参阅图6、图8和图10，在其中一些实施例中，固定座22的顶部开设有出烟孔2231，固定座22上还构造形成有连通气道2232，连通气道2232连通于雾化腔221与出烟孔2231之间，回气支道4的第三进液端口41与连通气道2232连通。通过采用上述结构设置，在固定座22的顶部开设有出烟孔2231，并在固定座22上还构造形成连通雾化腔221与出烟孔2231的连通气道2232，使得雾化腔221中雾化形成的烟雾，能够在用户抽吸形成的负压作用下，由出烟孔2231进入用户口中，以使用户达到模拟吸烟的效果。并且，回气支道4连通于连通气道2232与第一回液通道222的第一进液端口2221之间，用户在抽吸过程中，气溶胶形成基质在雾化芯31的加热作用下被雾化后，以在雾化腔221内的烟雾经连通气道2232及出烟孔2231流向用户口腔的过程中，产生的冷凝液能够在重力作用下，由连通气道2232的管壁进入回气支道4，进入回气支道4的冷凝液在储液腔11内形成的负压作用下，经回气支道4、第一回液通道222被吸收至储液腔11，有效防止用户抽吸到冷凝液，减少冷凝液在连通气道2232中流动产生的噪声，并避免冷凝液流入雾化腔221，提高用户体验。可以理解地，请结合参阅8，在其中一些实施例中，连通气道2232及出烟孔2231可以设置于固定座22的基座223上。
请结合参阅图5、图6和图10，在其中一些实施例中，第一回液槽225于基座223的外周面上迂回弯折延伸，以在基座223上构造形成迂回结构的第一回液通道222。通过采用上述结构设置，能够有效减少防止储液腔11中的气溶胶形成基质，通过第一回液通道222滴落至第二回液通道216，提高用户体验。
