Positive pressure type oxygen respirator

The invention relates to the technical field of lifesaving equipment, in particular to a positive pressure type oxygen respirator. The positive pressure type oxygen respirator comprises an air bag, a breathing assembly, an absorbing assembly, a cooling assembly and an oxygen generating assembly. The absorption assembly communicates with the breathing assembly and the air bag and is suitable for absorbing carbon dioxide. The cooling assembly communicates with the air bag and the breathing assembly, and the breathing assembly, the absorption assembly, the air bag and the cooling assembly jointly define a circulation air path. The oxygen generation assembly is communicated with the air bag, and an oxygen generation column is accommodated in the oxygen generation assembly. According to the positive pressure type oxygen respirator, the breathing assembly, the absorption assembly, the air bag and the cooling assembly jointly define the circulation air path, so that carbon dioxide in air exhaled by a user is removed
