Housing is square or rectangular body.

Positive plate in the oxygen generation chamber, left and right chamber, negative plate, left and right protruding chamber and left and right end cap are convex shape.

Hay tank has two up and down, hay tank is threaded up and down, by the sealing-ring sealing, its end heart all has the endoporus pipe, be covered with filter cap on the pipe of hole, acid system or alkali cation exchange resin and water be housed in the following hay tank, go up in the hay tank gac or carbon fiber are housed, thread fit has the filtration cover on the last hay tank, by the sealing-ring sealing, oxygen output pipe is arranged on the hay tank.

This invention compared with prior art has the following advantages: (1) is low than molecular sieving atmospheric oxygen mechanism of qi cost, price low 50%; (2) low than chemical method oxygen generator cost of use, oxygen uptake always took 0.5 yuan of less than in one hour; (3) existing electrolysis oxygen generator structural shape is reasonable in design, easy for operation, and oxygen purity Gao Keda is more than 99%; (4) system oxygen speed is fast, but continuous oxygen generation; (5) not limited by the region, can use in the highlands of airtight or atmosphere draught-free place and air starvation.
