Abstract
An anesthetic evaporator is provided. The anesthetic evaporator includes a housing, an anesthetic agent storage tank, a cover, a mechanical pressure relief assembly connected with the anesthetic agent storage tank, and a linkage mechanism. The mechanical pressure relief assembly is provided with a first state in which a pressure within the anesthetic agent storage tank is maintained and a second state in which a pressure within the anesthetic agent storage tank is released. When adding an anesthetic agent, an operation action on the anesthetic evaporator drives the linkage mechanism, and the linkage mechanism drives the mechanical pressure relief assembly to be switched from the first state to the second state.
