Shaped respirator for insulation

The utility model relates to a respirator, in particular to a shaped respirator for insulation corresponding to the curves of the figure of the human face, solving the problem that in the prior art, gaps are formed on two sides of a nose, so the harmful bacteria can not be effectively kept outside and that mist can be easily generated on the lenses. The utility model comprises a respirator body which is stitched with a plurality of gauze layers and is characterized in that: an elastic shaping support which presses tightly the respirator body on the face is stitched among the gauze layers and is positioned on the bridge of the nose part of the respirator, extending toward two sides, a concave position corresponding to the bridge of the nose is formed in the center of the shaping support. With the structure, the respirator body of the respirator can be pressed tightly on the face of human body, so the gaps on two sides of the nose; with all of the breathed air passing through the filtering layer of the respirator body, the utility model improves the performance of filtering harmful bacteria and capacity of anti-infection.
