Dry snorkel for diving

摘要

A dry snorkel for diving comprises a snorkel tube, a float valve and a dry-type top discharge head. A soft plastic waterproof ring is mounted on a top end of the snorkel tube. The soft plastic waterproof ring has an air inlet communicating with the snorkel tube. A curved part is formed on the top end of the snorkel tube. The float valve is pivotally connected to a lower portion of the curved part. When a snorkel is under water, the float valve is turned up by the buoyancy of water to close the air inlet. When the top of the snorkel is above water, the float valve is turned down to open the air inlet. This design is simple and easy to assemble. It has few components and decreases the occurrence of choking on water efficiently whereby the diver breathes easily and comfortably and prolongs the diving time.
