Airway branching structure and oxygen generator

The utility model provides an airway shunt structure and oxygenerator, including metal airway body, metal airway body is equipped with first air port, second air port, third air port, fourth air port, fifth air port, sixth air port, first airway and second airway, first air port, second air port and third air port are communicated through first airway, fourth air port, fifth air port and sixth air port are communicated through second airway. The fourth air port, the fifth air port and the sixth air port are communicated through a second air channel, the third air port and the sixth air port are connected through an electromagnetic valve, the second air port and the fifth air port are connected with an air channel outlet through one-way valves respectively, and a pressure release valve is arranged between the first air channel and the second air channel. The oxygen generator has the beneficial effects that the air passage branching structure with high integration level and compact structure is provided, the nu
