A kind of atomising device having the switch of liquid out, including an ontology, one group connect ring, one go out liquid switch, an atomization mould group and a lid. It liquid switch should wherein be gone out sets the what group comprising a fixing seat, an elastic element and a sliding seat to connect in ring, the sliding seat system corresponds to a container and is equipped with sleeve and a plunger, and by the elasticity recovery of the elastic element, the opposite fixing seat carries out elevating movement to the sliding seat. Accordingly, when installation, the container system is inverted and sets in the what sliding seat, it penetrates the plunger in the bottleneck of the container and gives temporary stopping, by press section Hou one of on the next what lid, the end of the plunger can temporarily remove the bottleneck, and the solution to be atomized is enabled to flow into the reservoir by the casing, most Hou, which is discharged to be atomized again by the atomization mould group, sprays the solution to be atomized, and the convenience when use of great Fu Ti Noboru.一種具出液開關的霧化裝置，包括一本體、一組接環、一出液開關、一霧化模組及一蓋體。其中該出液開關包含一固定座、一彈性元件及一活動座而設於該組接環內，該活動座係對應一容器而設有一套管及一柱塞，且該活動座藉該彈性元件之回復彈性而相對該固定座進行升降運動。據此，安裝時，該容器係倒置設於該活動座內，使該柱塞穿入該容器之瓶口內並予以暫時性封閉，按下位於該蓋體上之一按壓部後，該柱塞之末端會暫時移開該瓶口，令該待霧化溶液通過該套管而流入該儲液槽內，最後再由該霧化模組釋放霧化噴出該待霧化溶液，而大幅提昇使用時的便利性。
