Air permeable mask

Abstract

The present disclosure relates to a mask providing oxygen and removing water vapor in which a functional layer for oxygen production, moisture removal and better air quality is embedded; the functional layer can be inserted between an outer layer and an inner layer of the mask, taken as an inner layer or a sole layer, or held in a receiving pocket or attach/adhere to an innermost side of the mask; the functional layer comprises metal peroxide, metal superoxide, metal oxide and nonmetal oxide to remove water vapor and provide oxygen; the metal peroxide is selected from the group consisting of magnesium peroxide, potassium peroxide, sodium peroxide and calcium peroxide; the metal superoxide comprises potassium superoxide or sodium superoxide; the metal oxide is selected from the group consisting of magnesium oxide, calcium oxide and sodium oxide; the nonmetal oxide can be silicon dioxide.

What is claimed is: 
     
         1 . An air-permeable mask providing oxygen and removing water vapor, comprising a functional layer for oxygen production and moisture removal. 
     
     
         2 . The air-permeable mask of  claim 1 , wherein said functional layer is embedded between an outer layer and an inner layer of the air-permeable mask. 
     
     
         3 . The air-permeable mask of  claim 1 , wherein said functional layer is the inner layer of the air-permeable mask. 
     
     
         4 . The air-permeable mask of  claim 1 , wherein said functional layer is replaceable and held in a receiving pocket of the air-permeable mask. 
     
     
         5 . The air-permeable mask of  claim 1 , wherein said functional layer attaches or adheres to an innermost side of the air-permeable mask. 
     
     
         6 . The air-permeable mask of  claim 1 , wherein said functional layer is the sole layer of the air-permeable mask. 
     
     
         7 . The air-permeable mask of  claim 1 , wherein said functional layer is made of an air-permeable material comprising an oxide having a metal peroxide to remove water vapor and provide oxygen. 
     
     
         8 . The air-permeable mask of  claim 7 , wherein said metal peroxide in the functional layer comprises at least one member selected from the group consisting of: magnesium peroxide, potassium peroxide, sodium peroxide, and calcium peroxide. 
     
     
         9 . The air-permeable mask of  claim 7 , wherein said oxide comprises a powdered or fine granulated substance. 
     
     
         10 . The air-permeable mask as recited in  claim 7 , wherein said oxide comprises at least a member selected from the group consisting of: metal peroxide, metal superoxide, metal oxide, and nonmetal oxide. 
     
     
         11 . The air-permeable mask of  claim 7 , wherein said oxide is a metal superoxide to remove water vapor and provide oxygen. 
     
     
         12 . The air-permeable mask of  claim 11  wherein said metal superoxide comprises at least a member selected from the group consisting of: potassium superoxide, and sodium superoxide. 
     
     
         13 . An air-permeable mask providing oxygen and removing water vapor, comprising a functional layer for oxygen production and moisture removal, wherein said functional layer is made of an air-permeable material comprising an oxide having a metal peroxide to remove water vapor and provide oxygen, and wherein said oxide is selected from the group consisting of: a metal oxide, and a nonmetal oxide. 
     
     
         14 . The air-permeable mask of  claim 13 , wherein said metal oxide comprises at least a member selected from the group consisting of: magnesium oxide, calcium oxide, and sodium oxide. 
     
     
         15 . The air-permeable mask of  claim 13 , wherein said nonmetal oxide is silicon dioxide. 
     
     
         16 . The air-permeable mask of  claim 1 , wherein the air-permeable mask comprises at least a member selected from the group consisting of: cotton, gauze, paper, a surgical function, an activated carbon, and an N95 respirator.
