Second breathing pipeline 150 includes first interface 151；
Electronics eduction valve 130 includes lose heart entrance 131 and air bleed outlets 132；
The discouraged entrance 131 of electronics eduction valve 130 is connected with above-mentioned first interface 151；Electronics eduction valve 130 it is discouraged go out
Mouth 132 passes through the first check valve (not shown) and atmosphere；And electronics eduction valve 130 is electrically connected with main frame 110.
Typically, the gas flow for sucking or breathing out every time when tidal volume typically refers to user's normal respiration, in breathing apparatus
It is the tidal volume exported when user 160 supplies that the tidal volume of middle setting, which is often referred to suck gas flow, i.e. breathing apparatus,.Breathing apparatus
Main frame 110 can to breathing apparatus export tidal volume be controlled, in air-breathing, main frame 110 can be according to set in advance
Ventilating mode and parameter convey gas to user 160.Breather valve 120 is used to ensure the first breathing pipeline 140 and the second respiratory siphon
The unicity of the interior air-flow of road 150.Electronics eduction valve 130 is used to carry out aerial drainage to the tidal volume in user's breathing pipeline, i.e., by the
Part tidal volume in two breathing pipelines 150 lets out.
Exemplary, the aerating system that the utility model embodiment is provided goes for newborn emergency transhipment breathing
In equipment.Outlet interface 111 of the gas through main frame 110 of breathing apparatus output is exported, and is reached after the first breathing pipeline 140
Breather valve 120, in air-breathing, the inlet valve (not shown) in breather valve 120 is opened, and gas enters the second breathing pipeline 150,
It is provided with electronics eduction valve 130 on second breathing pipeline 150, electronics eduction valve 130 is by the part in the second breathing pipeline 150
