The invention discloses a self-generating type life buoy. The self-generating type life buoy is provided with a life buoy capsule body which is internally provided with four diaphragms uniformly distributed; the four diaphragms are respectively provided with a generating unit; each diaphragm is provided with a miniature boosting gas pump which is connected with a miniature gas motor, and each miniature gas motor is directly provided with a miniature permanent magnet generator so as to form the generating unit; the life buoy capsule body is also internally provided with a rectifier and a storage battery; four LED lamps are uniformly arranged on the life buoy capsule body; a swimmer swims with the life buoy, sea waves surge to extrude the life buoy capsule body, gas flows among the four diaphragms to drive the miniature boosting gas pumps to operate and output pressure gas and further push the miniature gas motors to rotate, the rotation of the miniature gas motors directly drives the miniature permanent magnet generators to rotate and generate power, power is rectified into direct-current power by the rectifier and then is transmitted into the storage battery for storage, and the storage battery is connected by a cable to light the LEDs so as to realize self-generating illumination.
