Abstract: A diving mask having a lens providing a wide view field, which is formed by glueing together of multiple glasses, using a glue with elastic and flexible properties. The planes of the connection between the glasses is designed to overlap or be parallel with the line of sight.

Abstract: A diving snorkel having a mouth portion and a main pipe molded from thermoplastic materials. There are two extending folding pieces and two matching recesses on the upper end. After the two folding pieces are pressed into the recesses by the external force, an anti-water piece is formed.
Abstract: A structural improvement of a diving mask which consists of a main frame, a sub-frame, a lens and a skirt. Tenons are provided on the sub-frame, engaging mortises on the lens. A soft connecting edge is provided on the skirt, which is closely connected with a periphery of the lens. A rigid structure is established by the tenon jointing the sub-frame with the lens, and the connecting frame of the skirt is closely connected with periphery of the lens, when the main frame is connected with sub-frame. This construction allows the diving mask lens removal and keeps a stable connecting state after its assembly.
