Breathable mask for snorkeling and equipment having the same

Abstract

A breathable mask for snorkeling is provided, which includes a body and an intake conduit in fluid communication with the body's interior. The body includes a main frame, a viewing window, a waterproof skirt, an intake passage and a drain valve. The waterproof skirt has a partition dividing the interior into an upper chamber configured to accommodate a user's eyes only and a lower chamber configured to accommodate the user's nose only. The intake passage is only formed between the intake conduit and the lower chamber, and provided with a one-way valve for fresh air from outside unidirectionally flowing through the intake passage and entering the lower chamber. The drain valve is provided at a lower portion of the body so that air exhaled from the user's nose is capable of being limited to be unidirectionally discharged outwards from the lower chamber through the drain valve only.

What is claimed is: 
     
         1 . A breathable mask for snorkeling, comprising:

   wherein the waterproof skirt is configured to suitably fit a face of a user and has a partition dividing the interior of the body into an upper chamber and a lower chamber, which are isolated from each other, such that when the user wears the breathable mask for snorkeling through a fastening device, the partition rests above an outer contour of a nose of the user, allowing the upper chamber to be configured to accommodate eyes of the user only and the lower chamber to be configured to accommodate the nose of the user only;   characterized in that the body further comprises:
 an intake passage only formed between the intake conduit and the lower chamber, and provided with a one-way valve only for fresh air from outside unidirectionally flowing through the intake passage and entering the lower chamber; and 
 a drain valve provided at a lower portion of the body so that air exhaled from the nose of the user is capable of being limited to be unidirectionally discharged outwards from the lower chamber through the drain valve only.

 wherein the body comprises:
 a main frame; 
 a viewing window embedded within the main frame; and 
 a waterproof skirt embedded with the main frame and the viewing window, 
 wherein the waterproof skirt is configured to suitably fit a face of the user and has a partition dividing the interior of the body into an upper chamber and a lower chamber, which are isolated from each other, such that when the user wears the breathable mask for snorkeling through a fastening device, the partition rests above an outer contour of a nose of the user, allowing the upper chamber to be configured to accommodate eyes of the user only and the lower chamber to be configured to accommodate the nose of the user only; 
 
   characterized in that the body further comprises:
 an intake passage only formed between the intake conduit and the lower chamber, and provided with a one-way valve only for fresh air from outside unidirectionally flowing through the intake passage and entering the lower chamber; and 
 a drain valve provided at a lower portion of the body so that air exhaled from the nose of the user is capable of being limited to be unidirectionally discharged outwards from the lower chamber through the drain valve only. 
   
     
     
         10 . The breathable equipment for snorkeling of  claim 9 , wherein the snorkel is a dry top snorkel and is independent of the breathable mask for snorkeling. 
     
     
         11 . The breathable equipment for snorkeling of  claim 9 , wherein the waterproof skirt further includes a nose covering portion, and the lower chamber is jointly defined by the nose covering portion and the partition. 
     
     
         12 .
