As can be seen from fig. 6 and 7, the fresh air components in the vortex ring generated by the vortex ring air supply device with high fresh air volume of the present invention are significantly higher than the fresh air components in the vortex ring generated by the conventional vortex ring air supply device, which means that the fresh air storage cylinder stores more fresh air, and the entrainment effect of the vortex ring on the fresh air in the generation stage is enhanced, so that the generated vortex ring carries more fresh air, thereby realizing the generation of the vortex ring with high fresh air volume.
