Furthermore, the mask body adopts a four-layer structure, and is respectively provided with a surface cloth layer, a heat-preservation fiber layer, a filtering layer and an inner cloth layer from outside to inside.
Furthermore, the nose filter screen is of a four-layer structure and is respectively provided with a surface cloth layer, a heat-preservation fiber layer, an activated carbon filter cotton layer and an inner cloth layer from outside to inside.
Furthermore, one nostril is inserted and is passed through the hose and be communicated with one the nose ventilation chamber, the nostril is inserted for screw thread formula silica gel concentric reducer nostril.
Further, the inner layer of the mask body is provided with a sealing piece.
Further, the sealing element is a nose clip or a concave eye socket soft cushion belt which can be tightly attached to the nose.
Further, a mask comprising the cavity-divided breathing mask.
Further, a protective garment comprising the cavity-divided breathing mask.
The utility model has the advantages that:
a divide cavate breathing mask, set up the mouth filter, the filter equipment that the mouth filter breathes as the mouth sets up the nasal filtration net, nasal ventilation chamber and nostril are inserted, the nostril is breathed and is inserted two nostrils through the nostril, the nasal filtration net of installation and the direct free breathing exchange in the external world on the nasal ventilation chamber realize that the mouth breathes and the nose breathes and separate, better air permeability has, the carbon dioxide of avoiding human body exhalation is in time not got rid of and is inhaled by self in the mask, cause the oxygen deficiency to lead to phenomena such as dizziness, brain bloated, chest distress, vomiting, syncope. The utility model discloses a divide cavate breathing mask when hugging closely facial, when also can not cause when deep breathing protruding with the problem of recessed, the breathing effect is good in better and the gauze mask of gauze mask border leakproofness, consequently has better filtration barrier propterty. Simultaneously the utility model discloses set up a mouth filter and two nose filter screens, reduced raw and other materials, reduced use cost, and accomplish the minimizing of discarded object.
