Abstract: A full-face diving mask includes a mask and a breathing tube. The mask includes an outer frame, a lens housing and a fitting mask. The fitting mask includes a partition plate. The partition plate and the inner surface of the lens housing define an observation chamber on the top and a breathing chamber below. The partition plate includes at least one air intake port to allow inhaled air to be guided and circulated through at least one air intake passageway from the observation chamber toward the breathing chamber. The breathing chamber is further provided with an air compartment partition plate connected to the partition plate to define an air discharge compartment. The air compartment partition plate is provided with at least one air discharge port to allow exhaled air to be guided through at least one air discharge passageway from the air discharge compartment and discharged along the breathing tube.

Abstract: An improved hydrodynamic sports snorkel for use in swim training, exercise and other recreational activities, which facilitates efficient swimming by eliminating the need for a swimmer to turn their head to the side for breathing. The sport snorkel device provides a novel design that significantly reduces drag and resistance, including by directing breathing tubes down the sides of the chin and under the jaw line toward the neck, around the neck and rejoining and going to the surface at the back of the neck behind the swimmer's head. This novel design with tubes running under the jawline and behind the head significantly reduces the portion of snorkel tubing directly in the water flow stream and thus reduces drag and resistance. The sport snorkel device also allows the swimmer to hold the snorkel solely by the mouthpiece without the need to fixedly attach the device to the swimmer's head or goggles.
