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.
