The invention provides a humidifying structure of a disinfecting machine, in which the interior of a container for collecting atomized gas is connected with a windshield frame having at least one side that must maintain a predetermined gap with the contact periphery, so that the gas at a reserved gap of the windshield frame periphery may flow between a mist collection box and the windshield frame to form a gas guide gap with a turnaround pattern, thereby allowing the disinfecting gas that has been atomized to be gaseous to be guided out along the aforementioned gas guide gap and discharged toward the outlet of a sealing cover configured on the top of the disinfecting machine, and enabling the discharged sterilizing gas to be in a better dry state.一種消毒機之加濕結構,是採在消毒機其間允許被霧化的氣體作為收集的容器內部結合一至少一側或以上必須和接觸周邊保持一預設間隙的擋風架,使該氣體在擋風架周邊的預留缺口是與霧氣收集盒之間流動而形成一具轉折形態的氣體引導間隙,以利被霧化趨近氣態的消毒氣體能循著前述的氣體引導間隙引出,並朝著消毒機其頂端組設的封蓋出口外排出,使該排出的消毒氣體獲有較佳的乾燥狀態。1‧‧‧內置架2‧‧‧固定架21‧‧‧底板31‧‧‧隔板32‧‧‧上板4‧‧‧霧氣收集盒41‧‧‧透孔42‧‧‧封蓋421‧‧‧出口43‧‧‧氣體引導間隙5‧‧‧擋風架51‧‧‧缺口6‧‧‧單元消毒機7‧‧‧單元外箱91‧‧‧液態的水分子92‧‧‧消毒氣體
