when the detection result meets the set anesthetic gas concentration threshold, the anesthesia control processor controls a sleeve motor to start, the sleeve motor drives a sleeve synchronous wheel to rotate for a certain angle through a sleeve synchronous belt, the sleeve synchronous wheel drives a support rod sealing bearing to rotate for a certain angle on a mixing support rod, so that the mixing rotary sleeve is driven to rotate for a certain angle along a conical bearing, a pipeline exhaust nozzle on the S-shaped pipeline rotates for a certain angle in an arc-shaped air nozzle slideway, the pipeline exhaust nozzle enters an air nozzle hole along an arc-shaped sliding groove, the anesthetic gas which meets the standard after mixing flows into an anesthetic gas guide pipe through the air nozzle hole, and the anesthetic gas temporary storage pipe is temporarily stored or supplied with the anesthetic gas through a guide one-way valve;
step three, temporarily storing or supplying anesthetic gas;
a temporary storage air pressure sensor in the anesthetic gas temporary storage cylinder detects the pressure to ensure that the anesthetic gas air pressure in the anesthetic gas temporary storage cylinder is within a threshold range; when the supply of anesthetic gas is needed, the anesthesia control processor controls the adjusting motor to start, the adjusting motor drives the adjusting sleeve to rotate on the adjusting bearing, the adjusting rotating shaft extends out or retracts in the adjusting sleeve, the active push plate is driven to be close to or far away from the anesthetic hose on the bottom surface of the anesthetic gas temporary storage cylinder, and the anesthetic gas in the anesthetic gas temporary storage cylinder is pushed to be actively supplied to the anesthetic hose.
