A ball type high concentration oxygen capsule is provided to supply oxygen of high concentration supplied from an oxygen supply device to the ball type high concentration oxygen capsule to let a user breathe in oxygen of high concentration. A ball type high concentration oxygen capsule includes a cover body(10), a door(20), front, rear and upper transparent windows(50), air injection tools(52,52'), a safety check valve, an outer cover(90), a support(200), and an automatic control device(60). The air injection tools are mounted on the front of the cover body to inject oxygen of high concentration by using an air injector(80). The safety check valve is mounted on the front of the cover body to maintain the air pressure constant. The outer cover encloses the outside of the cover body. The automatic device adjusts the oxygen and the air automatically.
