The embodiment of the utility model discloses a breathing shield which comprises a shield body 1 and a filter layer 2, wherein the breathing shield can be a nose mask shown in figure 1 or a mouth mask shown in figure 2.

Wherein, the mask body 1 is used for covering and buckling the nose and/or mouth, the mask body 1 can be provided with a wearing structure 3 for fixing the breathing shield on the head of a wearer, the wearing structure 3 can be a bandage or the wearing structure 3 can be an elastic band for hanging on the head or ear, the filter layer 2 is arranged in the mask body 1, the filter layer 2 can be arranged in the mask body 1, or can be arranged on one side of the mask body 1 facing to the face of the wearer or one side of the mask body away from the face of the wearer, and the filter layer 2 can be fully distributed on the whole mask body 1, or can be only arranged on the mask body 1 corresponding to the mouth and/or the nose, the filter layer 2 is made of a material which is air-permeable and has good filtering performance, such as non-woven fabric, the filter layer 2 at least has a fold structure 6 at the position covering the nose and/or the mouth, and the filter layer 2 can integrally adopt the fold structure 6, it is also possible that the filter layer 2 has a pleated structure 6 at a local position, the pleated structure 6 has a plurality of densely arranged pleats, and the pleated structure 6 maintains a pleated state in both the worn state and the unworn state of the filter layer 2.

Compared with the prior art, the breathing shield provided by the embodiment of the utility model has the advantages that the filter layer 2 is provided with the fold structure 6 at the position covering the nose and/or the mouth, and the fold structure 6 does not disappear due to wearing, so that the filtering area of the breathing shield can be increased, and the structural rigidity of the position can be improved, thereby reducing the resistance during breathing, avoiding the feeling of breath holding, avoiding the problem of collapse of the breathing shield at the mouth and the nose during breathing, and achieving the purposes of improving wearing comfort and filtering effect.

Preferably, the pleated structure 6 of the filter layer 2 includes a plurality of transverse pleats, which means that the length direction of the pleats is the same as the length direction of the mask body 1, i.e., the left and right direction in fig. 1 and 2; alternatively, the corrugation structure 6 of the filter layer 2 comprises a plurality of longitudinal corrugations, which means that the length direction of the corrugations is perpendicular to the length direction of the mask body 1 and is the same as the width direction of the mask body 1, i.e. the up-down direction in fig. 1 and 2; alternatively, the corrugation structure 6 of the filter layer 2 comprises a plurality of transverse corrugations and a plurality of longitudinal corrugations which cross each other.

Further, when the respiratory mask is worn, vertical stretching of the respiratory mask may occur due to the facial contour of the wearer, and if the pleated structure 6 of the filter layer 2 is a horizontal pleat, the pleated structure 6 of the filter layer 2 is easily deformed by the vertical stretching during wearing, and the structural rigidity is affected, and therefore, the pleated structure 6 of the filter layer 2 includes at least a plurality of vertical pleats.

It can be understood that if the corrugated structure 6 penetrates the whole mask body 1 or extends to most of the mask body 1 along the length direction or width direction of the mask body 1, it is easy to cause the mask body 1 not to be well attached to the face, a gap is formed between the mask body 1 and the face, so that air can flow through the gap to make the respiratory mask lose the application function, therefore, the corrugated structure 6 on the filter layer 2 is preferably only arranged at the position of the mask body 1 corresponding to the mouth and/or nose, in this case, the filter layer 2 can extend outwards at the two ends or around the corrugated structure 6 to form an attaching structure for attaching to the face, or the mask body 1 can form an attaching structure for attaching to the face around the corrugated structure 6 of the filter layer 2, so that an attaching structure with a sufficient area is formed between the mask body 1 and the face, and air can only flow through the corrugated structure 6 of the filter layer 2, thereby ensuring the filtering effect of the breathing shield.

Preferably, in the embodiment of the present invention, as shown in fig. 3, the side of the corrugated structure 6 close to the face and/or the side far from the face is provided with a lining 7 to avoid the corrugated structure 6 from being exposed, and the lining 7 may be made of lining paper or other macroporous soft materials.
