Further, the filter layer is circular.

Further, the outer edges of the mask body and the filter layer are provided with sealed edges.

Furthermore, a supporting aluminum strip is arranged in the sealed cotton strip.

The utility model discloses a theory of operation:

the multi-cavity filtering protective mask is characterized in that an active carbon fiber layer, a filtering cotton layer and a non-woven fabric layer are sequentially sewn in the middle of a mask body to form effective breathing filtration; the breathing cavity formed by connecting and combining the mouth cavity and the nasal cavity is arranged on the inner surface of the mask body corresponding to the filter layer, and the mask can be tightly attached to the face under the matching action of the sealing cotton strip and the supporting aluminum strip, so that the mouth and nose respiratory tract can well breathe the filter layer to purify the filtered air, and simultaneously, the phenomenon that bad breath breathed out from the oral cavity cannot occur in the nasal cavity is ensured; breathing cavity both sides still are provided with the air vent, prevent that the whole face of hugging closely of gauze mask body from causing the discomfort.

The utility model has the advantages that:

1. the utility model only arranges the three filter layers of the activated carbon fiber layer, the filter cotton layer and the non-woven fabric layer in the middle of the mask body, efficiently utilizes the filter layers to purify air, reasonably allocates resources, reduces the waste of unnecessary raw materials and saves the manufacturing cost of the mask;

2. the utility model arranges a convex breathing cavity on the inner surface of the mask body, when wearing, the breathing cavity can be tightly attached to the face, thereby avoiding the conditions of local air leakage and poor filtering effect caused by insufficient sealing performance of the traditional mask;

3. the breathing chamber is divided into an oral chamber and a nasal chamber which are separated from each other, so that the situation that gas exhaled by the mouth and the nose is connected with each other is avoided;

4. the nasal cavity is tightly attached to the face and is completely sealed, so that fog cannot leak out, and the mirror surface of a person wearing the glasses is prevented from being fogged;

5. the mask body is provided with the air vent, can make the facial normal ventilation outside the breathing cavity, improves the comfort level.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in figure 1 and figure 2, the multi-chamber filtering protective mask of the utility model comprises a mask body 1, wherein elastic hanging belts 5 are symmetrically arranged at the two ends of the mask body 1, and a circular filter layer 2 is sewn in the middle of the mask body 1. The filter layer 2 comprises an outer surface layer, a middle layer and an inner surface layer, the outer surface layer of the filter layer 2 is an activated carbon fiber layer, the middle layer of the filter layer 2 is a filter cotton layer, and the inner surface layer of the filter layer 2 is a non-woven fabric layer. The 1 internal surface protrusion of gauze mask body that filter layer 2 corresponds is provided with the breathing cavity of hoop seal, and the breathing cavity is provided with the support aluminium strip by sealed silver around forming, is provided with air vent 3 in the sealed silver, and the breathing cavity bilateral symmetry is provided with air vent 3, and the breathing cavity divide into oral cavity room 7 and nasal cavity room 6, and oral cavity room 7 is oval, and nasal cavity room 6 closely overlaps at oral cavity room 7 both ends to be located oral cavity room 7 upper end around forming "protruding" font. The outer edges of the mask body 1 and the filter layer 2 are both provided with sealed edges 4.

The multi-cavity filtering protective mask is characterized in that an active carbon fiber layer, a filtering cotton layer and a non-woven fabric layer three-layer filtering layer 2 are sequentially sewn in the middle of a mask body 1 to form effective respiratory filtration; a breathing cavity formed by connecting and combining an oral cavity 7 and a nasal cavity 6 is arranged on the inner surface of the mask body 1 corresponding to the filter layer 2, and the breathing cavity can be tightly attached to the face under the matching action of the sealing cotton strip and the supporting aluminum strip, so that the oral and nasal respiratory tracts can well breathe the filtered air through the filter layer 2, and meanwhile, the phenomenon that bad breath is exhaled from the oral cavity in the nasal cavity 6 is avoided; breathing cavity both sides still are provided with air vent 3, prevent that the whole face of hugging closely of gauze mask body from causing the discomfort.
