Claim 12:
13. The buffer valve as claimed in claim 1, wherein the buffer valve includes a valve body, a breathing cover and a floating ball; the valve body has a cylindrical shape and includes the inner chamber, an outer chamber, a partition portion, the outer gas hole, and a magnetic member; the outer chamber is configured to mount the gas connector; the breathing cover is configured to connect the breathing hole and includes an inner accommodating chamber, the inner gas hole, an external thread, and a central post; the external thread of the breathing cover is coupled and sealed with the breathing hole; an outer ring surface of the valve body is coupled and sealed with the inner accommodating chamber of the breathing cover; the central post of the breathing cover is mounted at a central position of a bottom of the inner accommodating chamber and is concentric with the axis to extend in the inner chamber; the inner gas hole is deviated from the axis of the inner accommodating chamber and is located at the inner end proximate to the inner annular surface to communicate with the breathing hole; the floating ball has a cylindrical shape and includes a spherical curved surface at its front end and a cylinder at its rear end, the cylinder has a cylindrical blind hole, a magnetic ring is installed inside the floating ball, the magnetic ring is a long ring located near the spherical curved surface, the axis extends to pass through the center of the spherical curved surface and the center of the magnetic ring and is concentric with the blind hole; the partition portion is located in the middle of the valve body to separate the inner chamber and the outer chamber at two ends, the inner chamber and the outer chamber are in communication with each other through the outer gas hole, the outer gas hole is located on the axis; the magnetic member is annular and is mounted on one side of the partition portion proximate to the inner chamber and is concentric with the outer gas hole; the floating ball is disposed in the inner chamber and can move back and forth on the central post; a mutually repulsive magnetic force Fm is generated between the magnetic ring of the floating ball and the magnetic member of the valve body; the shielding action is that when the magnetic force Fm mutually repelling the magnetic ring of the floating ball and the magnetic member of the valve body cannot resist the pressing force Fp generated by the pressure difference ΔP, Fm<Fp, the floating ball is secured to the outer gas hole; the releasing mechanism is that when the pressing force Fp generated by the pressure difference ΔP cannot resist the magnetic force Fm mutually repelling the magnetic ring and the magnetic member, Fm>Fp, the floating ball is displaced backward to the inner chamber and no longer covers the outer gas hole.
