The utility model relates to a sterilizing and drying device, which comprises a base, a liquid holding unit and a cover body. The base includes a gas supply unit； the liquid holding unit can form liquid communication with the base； the cover body is connected with the base, and the cover body can move or rotate between the open position and the closed position relative to the base. When the cover is in the open position, the liquid communication between the liquid holding unit and the base is blocked. Accordingly, the liquid supply of the liquid holding unit can be controlled by changing the position of the cover body.一種消毒烘乾裝置，包括底座、液體容置單元及蓋體。底座包括供氣單元；液體容置單元可與底座間形成液體連通；蓋體連接底座，且蓋體可相對底座於開啟位置及關閉位置之間移動或轉動。其中當蓋體位於開啟位置時，液體容置單元與底座間之液體連通被阻斷。據此，藉由蓋體之位置改變可控制液體容置單元之液體供給。
