Micro-pressure soft oxygen cabin

The invention relates to a micro-pressure soft oxygen cabin which comprises a soft oxygen cabin body and an air guide cylinder arranged on the soft oxygen cabin body in a penetrating mode, the air guide cylinder is used for communicating the inside and the outside of the soft oxygen cabin body, an opening and closing cover is hinged to a sealing face through a first hinge shaft, and the opening and closing cover can be attached to the sealing face and seal the end of the air guide cylinder when rotating. The first hinge shaft is located on the side, close to the bottom of the soft oxygen cabin body, of the air guide cylinder, after the soft oxygen cabin body is inflated, the axis direction of the first hinge shaft is perpendicular to the gravity direction, and the air guide cylinder is located in the middle of the soft oxygen cabin body in the height direction; the safety adjusting device is good in leakproofness, easy to open, rigorous and scientific in structure and capable of effectively saving cost and re
