Abstract
A diving snorkel provided in the proximity of at least one of an upper opening and a mouthpiece with at least one partition extending from an inner wall of a snorkel conduit and also extending longitudinally of the conduit so as to compartmentalize the conduit in its circumferential direction, and thereby enable undesirable inflow of water to be obstructed as effectively as possible and enable efficient purging of water which enters into the snorkel.
