Snorkel with one-way valve breath tube

Abstract

A snorkel with one-way breath tube comprises one J-shaped inhalant breath tube, one one-way valve inlet tube, one mouth piece, one one-way outlet tube and one exhalant breath tube. A snorkel with one-way breath tube allows air to flow in one direction. A swimmer inhales fresh air from J-shaped inhalant breath into his/her lung through one-way valve inlet tube and mouth piece. A swimmer exhales air from his/her lung into water through mouth piece, one-way valve outlet tube and exhalant breath tube. An extended long breath tube can attach onto J-shaped inhalant breath tube to allow swimmer swim or dive in deeper water. An extended long breath tube also can attach onto the exhalant breath tube to allow swimmer to exhale easily in deeper water.

1 . Snorkel with one-way valve breath tube comprising a J-shaped inhalant breath tube, one one-way valve inlet tubes, one mouth piece, one one-way valve outlet tube and an exhalant breath tube. 
   
   
       2 . The said one-way valve inlet tube in  claim 1  has installed inside a valve device that lets air flow in one direction from its inlet to its outlet. 
   
   
       3 . The said J-shaped inhalant breath tube in  claim 1  is a J-shaped inhalant tube that has an inlet and an outlet. Wherein the said outlet connects to the said inlet of the said one-way valve inlet tube in  claim 2  to let air flow from the said inlet of J-shaped breath tube in  claim 2  into the said one-way valve inlet tube in  claim 2 . 
   
   
       4 . The said mouth piece in  claim 1  has an upper teeth-bite end, one bottom inlet and one bottom outlet. Wherein the said bottom inlet connects to the said outlet of one-way valve inlet tube in  claim 2  to let fresh air flow from the inlet of the said J-shaped breath tube in  claim 2  into mouth piece. 
   
   
       5 . The said one-way valve outlet tube in  claim 1  has installed inside a valve device that lets air flow in one direction from its inlet to its outlet. Wherein the said inlet connects to the said bottom outlet of mouth piece in  claim 4  to let air flow from the said mouth piece to the said outlet. 
   
   
       6 . The said exhalant breath tube in  claims 1  is a curved tube or a straight tube, but preferably a curved tube, that has an inlet and an outlet. Wherein the said inlet connects to the said outlet of the said one-way valve outlet tube in  claim 5  to let air flow from the said one-way valve outlet tube into water through the said exhalant breath tube. 
   
   
       7 . The said J-shaped inhalant breath tube in  claims 1 ,  3  and  4  can connect to an extended long breath tube at its inlet to let swimmer inhale fresh air in deep water. 
   
   
       8 . The said outlet end of the said exhalant breath tube in  claims 1  and  6  can connect at its outlet to an extended long breath tube to let swimmer exhale easily without exhaling against the deep water pressure.
