Abstract

The invention discloses a single-inlet and single-out snorkeling mask, which includes a transparent mask body, a silicone mask body and a double-track breathing tube; An exhalation cavity, an inhalation cavity is formed between the outer surface of the silicone mask body and the inner surface of the transparent mask body, and the silicone mask body is provided with a first one-way valve plate that makes the inhalation cavity communicate with the exhalation cavity in one direction; The double-track breathing tube is arranged on the transparent mask body, the double-track breathing tube has an inhalation channel and an exhalation channel, and the tail end of the exhalation channel is provided with a second one-way valve plate. By adopting a double-track breathing tube and cooperating with the first one-way valve and the second one-way valve to form a single-inlet and single-outlet circulation structure, the intake and outlet are completely separated, so that there will be no waste and fresh air Convergence can solve shortness of breath and stuffy heart, and there is no need to worry about the exhaust gas being repeatedly inhaled and causing physical harm.
