Air intake system: Air and oxygen enter the mixing chamber through their respective inlets.
Mixing chamber: In the mixing chamber, air and oxygen are mixed under the action of a mixing device. The mixing process is influenced by factors such as the gas flow rate, the structure of the mixing chamber, and the design of the mixing unit.
Control system: The flow control valve of the air intake system is adjusted by sensors and controllers to ensure the stability of the mixing ratio. When the flow rate of air and oxygen changes, the sensor feeds the change back to the controller, who then adjusts the opening of the flow control valve according to the feedback signal to maintain the stability of the mixing ratio.
Outlet system: The mixed gas is output through the outlet system, which usually includes an outlet and a flow meter to observe and control the flow of the output gas.
