Full Face Snorkel Mask

Abstract

A full-face snorkel mask includes a mask assembly having a breathing chamber and a snorkel assembly having a fresh air intake channel and an exhaust air discharging channel. The fresh air intake channel guides fresh air into the breathing chamber and the exhaust air discharging channel discharges waste air from the breathing chamber. During snorkeling, fresh air is supplied via the fresh air intake channel to the breathing chamber for a user and the waste air exhaled from the user is discharged from the breathing chamber to the exhaust air discharging channel. Therefore, fresh air is separated from the waste air to prevent the user from repeatedly inhaling the waste air in the breathing chamber.

What is claimed is: 
     
         1 . A full-face snorkel mask, comprising:
 a mask assembly adapted for extending peripherally in a sealing engagement with a face of a user, wherein said mask assembly has a breathing chamber; and   a snorkel assembly upwardly extended from said mask assembly, wherein said snorkel assembly has a fresh air intake channel for guiding fresh air into said breathing channel and an exhaust air discharging channel communicating with said breathing chamber for discharging waste air therefrom.   
     
     
         2 . The full face snorkel mask according to  claim 1 , further comprising a valve assembly, wherein said mask assembly further has an air intake chamber isolated from said breathing chamber and communicated with said fresh air intake channel, wherein said valve assembly comprises one or more first non-return air valves provided at said mask assembly for only allowing the fresh air at said air intake chamber from said fresh air intake channel entering to said breathing chamber and for preventing the waste air entering to said air intake chamber. 
     
     
         3 . The full-face snorkel mask according to  claim 2 , wherein said mask assembly further has a vision section located at said air intake chamber. 
     
     
         4 . The full-face snorkel mask according to  claim 3 , wherein said mask assembly comprises a full face outer shell for covering the user's face and a half face inner shell attached thereinto for covering the user's nose and mouth, wherein said breathing chamber is formed between said half face inner shell and the user's face, and said air intake chamber is formed between said full face outer shell and said half face inner shell. 
     
     
         5 . The full-face snorkel mask according to  claim 4 , wherein said mask assembly further comprises a V-shaped face seal extended along a top edge of said half face inner shell for sealing against the user's face and across the nose bridge thereof to prevent the waste air being leaked from said breathing chamber to said air intake chamber. 
     
     
         6 . The full-face snorkel mask according to  claim 5 , wherein two of said first non-return air valves are provided at said half face inner shell below two side ends of said V-shaped face seal respectively. 
     
     
         7 . The full-face snorkel mask according to  claim 1 , wherein said mask assembly further has an air guiding channel formed at a peripheral portion of said mask assembly and extended from said breathing chamber to said exhaust air discharging channel for guiding the waste air being discharged from said breathing chamber to said exhaust air discharging channel. 
     
     
         8 . The full-face snorkel mask according to  claim 5 , wherein said mask assembly further has an air guiding channel formed at a peripheral portion of said mask assembly and extended from said breathing chamber to said exhaust air discharging channel for guiding the waste air to be discharged from said breathing chamber to said exhaust air discharging channel. 
     
     
         9 . The full-face snorkel mask according to  claim 8 , wherein said full face outer shell comprises an outer peripheral shell rim, a transparent visor coupled at said outer shell rim, and an inner peripheral shell rim coupled at said outer peripheral shell rim, wherein said air guiding channel is formed between said outer peripheral shell rim and said inner peripheral shell rim, and said half face inner shell is coupled at said inner peripheral shell rim. 
     
     
         10 . The full-face snorkel mask according to  claim 1 , wherein said fresh air intake channel and said exhaust air discharging channel are extended parallelly and upwardly. 
     
     
         11 . The full-face snorkel mask according to  claim 2 , wherein said valve assembly further comprises a second non-return air valve provided at said exhaust air discharging channel for preventing the waste air at said exhaust air discharging channel being returned back to said breathing chamber. 
     
     
         12 . The full-face snorkel mask according to  claim 1 , wherein said valve assembly further comprises a water prevention valve provided at said snorkel assembly for preventing water entering into said fresh air intake channel and said exhaust air discharging channel when said snorkel assembly is submerged below water. 
     
     
         13 . The full face snorkel mask according to  claim 12 , wherein said snorkel assembly comprises a snorkel body with two end-to-end channels to form said fresh air intake channel and said exhaust air discharging channel respectively and two air passages discretely formed at a top end of said snorkel body that two top openings of said air passages communicate with said fresh air intake channel and said exhaust air discharging channel respectively, wherein said water prevention valve is provided at each of said air passages. 
     
     
         14 . The full-face snorkel mask according to  claim 13 , wherein said water prevention valve comprises a floatable member movably disposed at each of said air passages and arranged in such a manner that:
 said floatable members float and seal at said top openings of said air passages when said snorkel assembly is submerged below water in order to prevent water entering into said fresh air intake channel and said exhaust air discharging channel, and   said floatable members drop down by their own weight at said air passages respectively when said top end of said snorkel assembly is located above water in order to open up said top openings of said air passages to let the fresh air entering into said fresh air intake channel and to discharge the exhaust air from said exhaust air discharging channel.   
     
     
         15 . The full-face snorkel mask according to  claim 14 , wherein said water prevention valve further comprises two sealing rings coupled at said top openings of said air passages to seal and engage with said floatable members when said snorkel assembly is submerged below water. 
     
     
         16 . The full-face snorkel mask according to  claim 15 , wherein said snorkel assembly further comprises a top snorkel cap coupled at said top end of said snorkel body, wherein said top snorkel cap has two individual air chambers that one of said air chambers communicates between said fresh air intake channel and one of said air passages and another said air chamber communicates between said exhaust air discharging channel and another said air passage. 
     
     
         17 . The full-face snorkel mask according to  claim 14 , wherein each of said floatable members has a conical shape that bases of said floatable members face toward said top openings of said air passages respectively to ensure said floatable members being floated properly there within.
