Among them, the person can pull the elastic band 41 with the help of the silicone plate 47, which achieves the effect of conveniently pulling the elastic band 41. By setting the auxiliary structure 4, the person can conveniently adjust the tightness of the elastic band 41, so that people with different head shapes can comfortably wear the breathing mask 6, thereby improving the applicability of the respirator.
