Patent ID: 6915800

Claim:
A water intake prevention device in combination with a snorkel comprising: an outer housing with at least one flow opening that allows air and water to flow therethrough, said outer housing further comprising a neck that is in communication with an airway tube of said snorkel, an inner housing that is connected on at least two joining surfaces to said outer housing such that said inner housing is fixed in position relative to said outer housing, said inner housing comprising a float hole in a top side thereof, at least one airway passage defined between said outer housing and said inner housing, said airway passage being in communication with said float hole and with said neck of said outer housing, and a float device contained in said inner housing; wherein when a water level is below said flow opening, air flows freely into said inner housing through said flow opening, out of said inner housing through said float hole, through said airway passage and through said neck of said outer housing, and when the water level is above a lower side of said flow opening, water flows into said inner housing, causing said float to rise on said water, and when the water level rises to a sufficient level, said float is forced into said float hole, thereby blocking said float hole so that no water enters said airway passage, and when the water level recedes, said float drops out of said float hole, again allowing a free flow of air through said airway passage.
