Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Chinese Patent Application No. 201830403931.5 filed Jul. 25, 2018, and Chinese Patent Application No. 201821298629.9 filed Aug. 13, 2018.TECHNICAL FIELD[0002]The present utility model relates to the technical field of diving supplies, and particularly to a full face dive mask.BACKGROUND ART[0003]The existing full face dive masks in the market have the following defects: firstly, the respiratory pipe cannot be folded to place, but only be disassembled to store, which leads to a greater possibility to lose it; secondly, a double-passage design is used for the respiratory pipe (two passages are respectively used for inhalation and exhalation), consequently a narrow inhalation air passage is formed, while the exhalation air passage is too long and narrow, which causes a difficulty for the exhaust gas to be discharged in time, hence a user may inhale a large amount of exhaust gas circularly with little fr...

Problems solved by technology

The existing full face dive masks in the market have the following defects: firstly, the respiratory pipe cannot be folded to place, but only be disassembled to store, which leads to a greater possibility to lose it; secondly, a double-passage design is used for the respiratory pipe (two passages are respectively used for inhalation and exhalation), consequently a narrow inhalation air passage is formed, while the exhalation air passage is too long and narrow, which causes a difficulty for the exhaust gas to be discharged in time, hence a user may inhale a large amount of exhaust gas circularly with little fresh air inhaled, and adverse reactions such as dyspnea caused by hypoxia are generated.
