Disclosure is an anesthetic evaporator locking structure for detachably connecting an anesthetic evaporator(100) to an anesthesia main machine, wherein the anesthetic evaporator(100) comprises a main body(10)； the anesthesia main machine comprises a driving element(230)； the anesthetic evaporator locking structure comprises a securing member(40) provided on the main body(10) and a mating member(210) provided on the anesthesia main machine； the securing member(40) and the mating member(210) mate with each other to form a primary locking mechanism, and when the anesthetic evaporator(100) is in an activated state, the driving element(230) limits the primary locking mechanism to realize secondary locking； and the anesthetic evaporator(100) futher comprises a handle(20) provided on the main body(10) and an unlocking device provided on the handle(20),and the unlocking device is used for unlocking the primary locking mechanism. The anesthetic evaporator locking structure can realize the primary mechanical locking and the secondary locking and has relatively high safety, and both the locking and unlocking processes can be operated by one hand, which is convenient and quick.
