Breathable mask for snorkeling and breathing tube thereof

Abstract

A breathable mask for snorkeling, including a body and a breathing tube connected with the body and including a tube body, is provided. The tube body has an upper end portion and a lower end portion opposite to the lower end portion, and further has an interior being longitudinally partitioned into an intake conduit and an exhaust conduit. The tube body is connected to the body through the lower end portion so that the breathing tube is suitably in fluid communication with an interior of the body. The upper end portion has an air inlet for inhaled air entering therethrough and flowing along the intake conduit to the lower end portion. An exhaust one-way valve is provided between the upper end portion and the lower end portion for exhaled air flowing into the exhaust conduit from the lower end portion and to be discharged outwards through the exhaust one-way valve.

What is claimed is: 
     
         1 . A breathing tube for snorkeling, comprising:
 a tube body having an upper end portion and a lower end portion opposite to the upper end portion, the tube body further having an interior formed with an intake conduit and an exhaust conduit, wherein:
 the exhaust conduit and the intake conduit are longitudinally partitioned by a dividing wall; 
 the upper end portion has an air inlet for inhaled air entering therethrough and flowing along the intake conduit to the lower end portion; and 
 an exhaust one-way valve is provided between the upper end portion and the lower end portion for exhaled air flowing into the exhaust conduit from the lower end portion and to be discharged outwards through the exhaust one-way valve; and 
 the dividing wall extends upward from the lower end portion and ends at a region above the exhaust one-way valve where the dividing wall is merged with a front sidewall or a rear sidewall of the tube body. 
   
     
     
         2 . The breathing tube of  claim 1 , wherein the dividing wall is merged with the rear sidewall of the tube body, and the exhaust one-way valve is disposed in an opening of the rear sidewall of the tube body. 
     
     
         3 . The breathing tube of  claim 1 , wherein the exhaust one-way valve is a mushroom valve. 
     
     
         4 . The breathing tube of  claim 1 , wherein the lower end portion is connected to a body of a breathable mask so that the breathing tube is suitably in fluid communication with an interior of the body; and the body includes:
 a main frame;   a lens embedded within the main frame;   a waterproof skirt, at least part of the waterproof skirt being embedded with the main frame and the lens, the waterproof skirt being configured to suitably fit a face of a user; wherein the waterproof skirt has a partition to divide 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, eyes of the user are accommodated in the upper chamber, and the nose of the user is accommodated in the lower chamber;   an intake passage formed between the intake conduit and the lower chamber; and   an exhaust passage formed between the exhaust conduit and the lower chamber, and the exhaust passage and the intake passage being independent of each other.   
     
     
         5 . The breathing tube of  claim 4 , wherein the exhaust passage is formed by two exhaust tunnels each jointly defined by the waterproof skirt and an inner surface of the lens, and arranged along an outer periphery of the lens. 
     
     
         6 . The breathing tube of  claim 1  further comprising a button, the button is sheathed on the tube body, faces the exhaust one-way valve, and is spaced apart from the exhaust one-way valve, so that when the user actuates the button, the button is capable of preventing the exhaust one-way valve from opening, and when the user does not actuate the button, the exhaust one-way valve is capable of being opened as usual. 
     
     
         7 . A breathable mask for snorkeling, comprising:
 a body; and   a breathing tube connected with the body, the breathing tube including a tube body, the tube body having an upper end portion and a lower end portion opposite to the upper end portion, the tube body further having an interior formed with an intake conduit and an exhaust conduit, wherein:
 the exhaust conduit and the intake conduit are longitudinally partitioned by a dividing wall; 
 the upper end portion has an air inlet for inhaled air entering therethrough and flowing along the intake conduit to the lower end portion; 
 an exhaust one-way valve is provided between the upper end portion and the lower end portion for exhaled air flowing into the exhaust conduit from the lower end portion and to be discharged outwards through the exhaust one-way valve; 
 the dividing wall extends upward from the lower end portion and ends at a region above the exhaust one-way valve where the dividing wall is merged with a front sidewall or a rear sidewall of the tube body; and 
 the tube body is connected to the body through the lower end portion so that the breathing tube is suitably in fluid communication with an interior of the body. 
   
     
     
         8 . The breathable mask of  claim 7 , wherein the dividing wall is merged with the rear sidewall of the tube body, and the exhaust one-way valve is disposed in an opening of the rear sidewall of the tube body. 
     
     
         9 . The breathable mask of  claim 7 , wherein the exhaust one-way valve is a mushroom valve. 
     
     
         10 . The breathable mask of  claim 7 , wherein the body comprises:
 a main frame;   a lens embedded within the main frame;   a waterproof skirt, at least part of the waterproof skirt being embedded with the main frame and the lens, the waterproof skirt being configured to suitably fit a face of a user; wherein the waterproof skirt has a partition to divide 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, eyes of the user are accommodated in the upper chamber, and the nose of the user is accommodated in the lower chamber;   an intake passage formed between the intake conduit and the lower chamber; and   an exhaust passage formed between the exhaust conduit and the lower chamber, and the exhaust passage and the intake passage being independent of each other.   
     
     
         11 . The breathable mask of  claim 10 , wherein the exhaust passage is formed by two exhaust tunnels each jointly defined by the waterproof skirt and an inner surface of the lens, and arranged along an outer periphery of the lens. 
     
     
         12 . The breathable mask of  claim 10 , wherein the lower end portion is at least partially integrally extended from the lens. 
     
     
         13 . The breathable mask of  claim 7 , wherein the breathing tube further comprises a button, and the button is sheathed on the tube body, faces the exhaust one-way valve, and is spaced apart from the exhaust one-way valve, so that when the user actuates the button, the button is capable of preventing the exhaust one-way valve from opening, and when the user does not actuate the button, the exhaust one-way valve is capable of being opened as usual.
