The invention provides a micro-mist treatment device, which mainly comprises a casing, a liquid storage container, an ultrasonic atomization unit, an infusion tube, at least one nozzle, and an inspection unit. Integrated into the housing, this can simplify the overall volume to reduce the space, and further facilitate subsequent management and maintenance, thereby reducing equipment costs and improving the convenience of use. In addition, since the liquid storage container can be alternately disposed in the casing, the present invention can be regularly maintained, and the liquid such as pure water, essential oil, or liquid medicine can be replaced to achieve the diversity of use, and at the same time, the old breeding can be reduced. All kinds of bacteria problems are safer for the user to use.本新型提供一種微霧處理裝置,主要由一殼體、一儲液容器、一超音波霧化單元、一輸液管、至少一噴嘴、及一檢驗單元所組成,本新型將上述各元件設備都整合於殼體,此舉能簡化整體之體積以減少佔用空間,再者,亦方便後續的管理及維修保養,藉以降低設備成本並增進使用之便利性。另外,由於儲液容器能夠替換地設置在殼體內,使本新型可定期維護保養,並且更換純水、精油、或藥液等液體,達到使用的多樣性,同時,可減少因為老舊滋生有各式的細菌問題,達到讓使用者使用時更安全之目的。
