Breathable mask

Abstract

A breathable mask is provided, which includes a body and a breathing tube in fluid communication with an interior thereof. The body includes a main frame, a lens, a waterproof skirt, a multi-channel connector, and intake and exhaust passages. The waterproof skirt has a partition dividing the interior of the body into upper and lower chambers, thereby accommodating the user's eyes and nose in the upper and lower chambers, respectively. The multi-channel connector has an upper end in fluid communication with the lower chamber. The intake passage is formed between the lower end portion of the breathing tube and the lower chamber. The exhaust passage is arranged upward along a periphery of the body to allow dirty air exhaled from the user to unidirectionally flow outward through the exhaust passage. The exhaust passage includes an exhaust tube with a bottom portion coupled to and communicating with the multi-channel connector.

What is claimed is: 
     
         1 . A breathable mask, comprising:
 a breathing tube having an upper end portion and a lower end portion opposite to the upper end portion, the breathing tube being formed with an intake conduit inside, the upper end portion being capable of preventing outer water from flowing in underwater and allowing fresh air inhaled by a user to enter therethrough and flow along the intake conduit to the lower end portion;   a body connected to the lower end portion of the breathing tube, and having an interior being in fluid communication with the breathing tube, the body comprising:
 a main frame; 
 a lens embedded within the main frame; 
 a waterproof skirt having a front portion being embedded with the main frame and the lens and a rear portion being configured to suitably fit a face of a user; wherein the waterproof skirt has a partition dividing the interior of the body into an upper chamber and a lower chamber, when the user wears the breathable mask through a fastening device, the partition rests above a nose of the user, and eyes and the nose of the user are accommodated in the upper chamber and the lower chamber, respectively; 
   wherein the body further comprises:
 a multi-channel connector having an upper end and a lower end, the upper end being in fluid communication with the lower chamber, the lower end being provided with a drain valve; 
 an intake passage formed between the lower end portion of the breathing tube and the lower chamber and provided with an intake one-way valve for the inhaled air unidirectionally flowing through the intake passage and entering the lower chamber; 
 an exhaust passage arranged upward along a periphery of the body to allow dirty air exhaled from the user to unidirectionally flow outward through the exhaust passage; 
 wherein the exhaust passage comprises an exhaust tube which has a bottom portion being coupled to an outer side of the multi-channel connector and communicating with the multi-channel connector. 
   
     
     
         2 . The breathable mask of  claim 1 , wherein he breathing tube further is formed with an exhaust conduit inside which is independent of the intake conduit, and the exhaust passage further comprises an exhaust tunnel formed between the exhaust conduit and the exhaust tube so that the dirty air exhaled by the user is capable of being discharged outwards from the multi-channel connector through the exhaust tube, the exhaust tunnel and exhaust conduit in sequence;
 wherein the exhaust tunnel extending along the periphery of the body is jointly defined by the waterproof skirt and an inner surface of the lens;   wherein the exhaust tube has a top portion communicating with the exhaust tunnel.   
     
     
         3 . The breathable mask of  claim 2 , wherein the intake one-way valve is disposed on the partition, and the intake passage is defined by the upper chamber and the intake one-way valve. 
     
     
         4 . The breathable mask of  claim 3 , wherein the body further comprises a bottom exhaust one-way valve being disposed in a region where the exhaust tube is coupled with the multi-channel connector, and the exhaust passage is defined by the bottom exhaust one-way valve, the exhaust tube and the exhaust tunnel. 
     
     
         5 . The breathable mask of  claim 1 , wherein the exhaust tube extends upward along the periphery of the body and an outer side of the breathing tube. 
     
     
         6 . The breathable mask of  claim 5 , wherein the body further comprises a top exhaust one-way valve disposed on a top portion of the exhaust tube, and the intake one-way valve is disposed on the partition;
 wherein the intake passage is defined by the upper chamber and the intake one-way valve, and the exhaust passage is defined by the top exhaust one-way valve and the exhaust tube.   
     
     
         7 . The breathable mask of  claim 6 , wherein the body further comprises a bottom exhaust one-way valve being disposed in a region where the exhaust tube is coupled with the multi-channel connector, and the exhaust passage is defined by the top exhaust one-way valve, the exhaust tube and the bottom exhaust one-way valve. 
     
     
         8 . The breathable mask of  claim 5 , further comprising a fastener sustaining the exhaust tube along the breathing tube. 
     
     
         9 . The breathable mask of  claim 1 , wherein the multi-channel connector has a nose connecting portion, a mouth connecting portion and a drain portion in fluid communication with one another, the nose connecting portion is in fluid communication with the lower chamber, the mouth connecting portion is provided with a mouthpiece to be contained in the mouth of the user, and the drain portion is provided with the drain valve for draining water accumulated within the body. 
     
     
         10 . The breathable mask of  claim 9 , wherein the body further comprises a nose-mouth one-way valve disposed in a region where the nose connecting portion is in fluid communication with the lower chamber, whereby only allowing fluid to unidirectionally flow from the lower chamber to enter the nose connecting portion through the nose-mouth one-way valve.
