Breathable mask and body thereof

Abstract

A breathable mask and a body thereof are provided. The body includes a main frame, a lens and a waterproof skirt. The waterproof skirt has a partition which divides the interior of the body into an upper chamber and a lower chamber. When the user wears the breathable mask, the partition is seated above the user's nose, the user's eyes are accommodated in the upper chamber, and the user's nose and mouth are accommodated in the lower chamber. The waterproof skirt also includes a bridge disposed across the lower chamber and divides the lower chamber into a nasal chamber and a mouth chamber below the nasal chamber. The bridge has an opening and an orinasal one-way valve adjacent to the opening. The orinasal one-way valve only allows a unidirectional fluid communication from the nasal chamber to the mouth chamber.

What is claimed is: 
     
         1 . A breathable mask, comprising:
 a body; and   a breathing tube in fluid communication with an interior of the body, the breathing tube including an intake conduit and an exhaust conduit independent of each other;   wherein the body comprises:
 a main frame; 
 a lens embedded within the main frame; 
 a waterproof skirt, at least partially embedded with the main frame and the lens, the waterproof skirt being configured to suitably fit a face of a user, the waterproof skirt having a partition to divide the interior of the body into an upper chamber and a lower chamber, whereby when the user wears the breathable mask through a fastening device, the partition is seated above a nose of the user, eyes of the user are accommodated in the upper chamber, and the nose and a mouth of the user are accommodated in the lower chamber; 
 an intake passage formed from the intake conduit to the lower chamber; and 
 an exhaust passage formed from the lower chamber to the exhaust conduit; 
   characterized in that:
 the waterproof skirt further comprises a bridge disposed across the lower chamber and dividing the lower chamber into a nasal chamber and a mouth chamber below the nasal chamber, whereby when the user wears the breathable mask, the nose of the user is accommodated in the nasal chamber, and the mouth of the user is accommodated in the mouth chamber; and 
 the intake passage is in fluid communication with the nasal chamber, the exhaust passage is in fluid communication with the nasal chamber, and the nasal chamber and the mouth chamber are suitably in fluid communication with each other through the bridge; and 
 the bridge has an opening and an orinasal one-way valve adjacent to the opening, and the orinasal one-way valve only allows a unidirectional fluid communication from the nasal chamber to the mouth chamber. 
   
     
     
         2 . The breathable mask of  claim 1 , wherein when the user wears the breathable mask, the opening is adapted to be distal from nostrils of the user, relative to the orinasal one-way valve which is adapted to be proximal to the nostrils of the user. 
     
     
         3 . The breathable mask of  claim 2 , wherein a total open area of the opening ranges 60 and 200 square millimeters (mm 2 ). 
     
     
         4 . The breathable mask of  claim 3 , wherein the opening has an inner boundary, and the bridge is formed with a central inner edge, in which the inner boundary and the central inner edge define a distance therebetween ranging from 20 to 80 millimeters (mm). 
     
     
         5 . The breathable mask of  claim 4 , wherein the distance between the inner boundary and the central inner edge ranges between 20 and 50 millimeters (mm). 
     
     
         6 . The breathable mask of  claim 2 , wherein the opening is formed by a plurality of holes spaced apart from each other. 
     
     
         7 . The breathable mask of  claim 2 , wherein the orinasal one-way valve has a central fixed portion and two diaphragms extending outward from the central fixed portion, the central fixed portion is fixed to the bridge, and the two diaphragms are only opened when airflows pass therethrough from the nasal chamber to the mouth chamber. 
     
     
         8 . The breathable mask of  claim 1 , wherein the exhaust passage includes an exhaust tunnel jointly defined by the waterproof skirt and an inner surface of the lens, and the exhaust tunnel extends along a periphery of the body. 
     
     
         9 . A body of a breathable mask, comprising:
 a main frame;   a lens embedded within the main frame;   a waterproof skirt, at least partially embedded with the main frame and the lens, the waterproof skirt being configured to suitably fit a face of a user, the waterproof skirt having a partition to divide the interior of the body into an upper chamber and a lower chamber, whereby when the user wears the breathable mask through a fastening device, the partition is seated above a nose of the user, eyes of the user are accommodated in the upper chamber, and the nose and a mouth of the user are accommodated in the lower chamber;   characterized in that:
 the waterproof skirt further comprises a bridge disposed across the lower chamber and dividing the lower chamber into a nasal chamber and a mouth chamber below the nasal chamber, whereby when the user wears the breathable mask, the nose of the user is accommodated in the nasal chamber, and the mouth of the user is accommodated in the mouth chamber; and 
 the bridge has an opening and an orinasal one-way valve adjacent to the opening, and the orinasal one-way valve only allows a unidirectional fluid communication from the nasal chamber to the mouth chamber. 
   
     
     
         10 . The body of  claim 9 , wherein when the user wears the breathable mask, the opening is adapted to be distal from nostrils of the user, relative to the orinasal one-way valve which is adapted to be proximal to the nostrils of the user. 
     
     
         11 . The body of  claim 10 , wherein a total open area of the opening ranges between 60 and 200 square millimeters (mm 2 ). 
     
     
         12 . The body of  claim 11 , wherein the opening has an inner boundary, and the bridge is formed with a central inner edge, in which the inner boundary and the central inner edge define a distance therebetween ranging from 20 to 80 millimeters (mm). 
     
     
         13 . The body of  claim 12 , wherein the distance between the inner boundary and the central inner edge ranges between 20 and 50 millimeters (mm). 
     
     
         14 . The body of  claim 10 , wherein the opening is formed by a plurality of holes spaced apart from each other. 
     
     
         15 . The body of  claim 10 , wherein the orinasal one-way valve has a central fixed portion and two diaphragms extending outward from the central fixed portion, the central fixed portion is fixed to the bridge, and the two diaphragms are only opened when airflows pass therethrough from the nasal chamber to the mouth chamber.
