High-efficiency water electrolysis oxygen production device

The invention provides a high-efficiency water electrolysis oxygen production device, and relates to the field of oxygen production, the high-efficiency water electrolysis oxygen production device comprises an electrolysis tank, an end cover is arranged at the top end of the electrolysis tank, an anode bar and a cathode bar are arranged in the electrolysis tank, water pipes provided with valves are arranged at the bottoms of the two sides of the electrolysis tank, and a sealing mechanism is arranged between the electrolysis tank and the end cover. The sealing mechanism comprises a filter plate arranged between the electrolysis tank and the end cover, a solid polymer electrolysis film is arranged on the filter plate, and sealing rings are arranged at the top and the bottom of the filter plate. By arranging the sealing mechanism, in the water electrolysis process, generated gas penetrates through the solid polymer electrolysis film and can be discharged through the exhaust assembly, and the gas is not prone to
