Abstract: A snorkeling breathing apparatus includes a mask, a first breathing tube assembly and a one-way exhaust valve. The mask includes an outer mask and a breathing mask arranged in the outer mask, the mask is equipped with a breathing chamber. The breathing tube assembly includes a first breathing tube and a one-way inhaling valve. The breathing tube is connected to the breathing mask through the inhaling valve. The exhaust valve is connected and mounted on the outer mask and the breathing mask. While inhaling, the inhaling valve conducts and air enters the chamber through the breathing tube. While exhaling, the exhaust valve conducts and air flows from the chamber to outside.

Abstract: The invention discloses a snorkeling breathing apparatus comprising a mask, a first breathing tube assembly and a one-way exhaust valve. The mask comprises an outer mask and a breathing mask provided within the outer mask and, equipped with a breathing chamber. The breathing tube assembly comprises a first breathing tube and a one-way inhaling valve. The breathing tube is connected to the breathing mask through the inhaling valve. The exhaust valve is connected and mounted on the outer mask and the breathing mask. While inhaling, the inhaling valve conducts and air enters the chamber through the breathing tube. While exhaling, the exhaust valve conducts and air flows from the chamber to outside. The invention aims at making an innovation to the breathing system by separating, the exhalation and suction mechanically, to make sure air in the breathing cavity is always fresh, and to increase the safety performance.
