具体而言，喷嘴20内的气体通道23与挤压空间53连通向挤压空间53内充气，将喷嘴20内的部分气流引流至挤压空间53内，用于挤压柔性容置件54。并且，储液组件50的下液口521与喷嘴20中的进液口212连通，在柔性容置件54被挤压时，储液腔541内的气溶胶生成基质通过下液口521流向喷嘴20的液体通道21内，最后从喷嘴20的出液口214喷出并与第一出气口233处的气体汇流形成雾化的气溶胶。
进一步地，喷嘴20上的第二出气口235与挤压空间53连通，喷嘴20上的进液口212与下液口521连通，这样喷嘴20中的部分气流可通过第二出气口235流向挤压空间53，进而挤压柔性容置件54，柔性容置件54内的气溶胶生成基质也在被挤压时通过下液口521流向喷嘴20的进液口212，进而流入液体通道21内，实现供液。

进一步地，喷嘴20包括主体24、及均凸出设置于主体24上的第一安装部27、第二安装部28和第三安装部29。主体24内形成有液体通道21及气体通道23，且主体24上开设有第一出气口233及出液口214，进气口231贯穿第一安装部27与气体通道23连通，进液口212贯穿第二安装部28与进液口212连通，第二出气口235贯穿第三安装部29与气体通道23连通。如此，在喷嘴20上凸出设置第一安装部27、第二安装部28及第三安装部29，可通过第一安装部27与气泵70套设，使气泵70与贯穿第一安装部27的进气口231连通，还可通过第二安装部28和第三安装部29与储液组件50套设连接，以利用第三 安装部29上的第二出气口235向储液组件50内部传输储液压力，且利用第二安装部28上的进液口212允许储液组件50内的气溶胶生成基质流向液体通道21。
具体到本实施例中，第一安装部27与气泵70套设连接，使喷嘴20与气泵70直接套设连接，两者之间不需要外接连接管来供气。并且，第二安装部28套设于外壳52的下液口521中，使储液组件50的下液口521与第二安装部28上的进液口212连通，第三安装部29套设于过气口523中，使第二出气口235与过气口523连通，已将喷嘴20直接套设连接于储液组件50上，储液组件50与喷嘴20之间不需要连接其他连接管，安装简单方便，且将管道集成在喷嘴20内，节省外接连接管的空间。
一些实施例中，柔性容置件54包括相互连接的开口端543和封闭端545，开口端543固定于外壳52内，下液口521对应开口端543开设于外壳52上，以允许柔性容置件54内的储液腔541与下液口521连通。并且，封闭端545悬空设置于外壳52内，以允许封闭端545在挤压空间53内流体的压力作用下收缩，进而将储液腔541内的气溶胶生成基质通过下液口521推出。
进一步地，封闭端545与外壳52之间预留有间隙以形成挤压空间53，如此封闭端545与外壳52之间的空间可作为挤压空间53，方便向挤压空间53内充入气体来挤压封闭端545，使柔性容置件54被挤压下液。
一些实施例中，储液组件50还包括固定件56，开口端543具有外翻边沿544，外翻边沿544通过固定件56贴合固定于外壳52的内壁上，以通过外翻边沿544固定连接柔性容置件54和外壳52。

并且，喷嘴20内形成有相互独立的液体通道21和气体通道23，喷嘴20上开设有均与气流通道23连通的进气口231、第一出气口233及第二出气口235，且喷嘴20上开设有均与液体通道21连通的进液口212和出液口214，第一出气口233与出液口214连通并汇合形成喷射通道，第二出气口235用于输出气体通道23内的部分气体，以向储液腔541内的气溶胶生成基质传输出液压力。
其中，气泵70可直接套设于喷嘴20上与进气口231连通，气泵70通过进气口231向气体通道23内送气，气体通道23内的气流分为两路，一路通过第二出气口235向储液腔541内的气溶胶生成基质传输出液压力，使储液腔541内的气溶胶生成基质在气体压力的作用下流向进液口212，进而进入液体通道21，另一路流向第一出气口233来雾化从出液口214喷出的气溶胶生成基质，形成雾化后的气溶胶。如此，气泵70、喷嘴20及储液组件50三者相互套设便可实现供液及供气，将管路集成到喷嘴20内部，不需要单独外接连接管，节省排布连接管的空间，且可防止连接管内残留气溶胶生成基质，能够有效利用气溶胶生成基质，进而防止浪费。
