Abstract

Official abstract text for this publication.

The disclosure relates to a diving mask comprising a body having a faceplate and a flexible skirt, and a snorkel extending a top portion of the body. The body includes an exhaled air exhaust device that puts the bottom chamber in fluid-flow connection with the air duct of the snorkel. The exhaled air exhaust includes at least a first check valve arranged to allow exhaled air from the bottom chamber to flow towards the air duct of the snorkel during a stage in which the user is breathing out, the first check valve being closed during a stage in which the user is breathing in.

First claim

Opening claim text (preview).

The invention claimed is: 1. A diving mask, comprising: a body having a faceplate and a flexible skirt, said flexible skirt including a partition separating a top chamber for vision from a bottom chamber for breathing, the partition being arranged to bear on the nose of a user so that the mouth and nose of the user are situated in the bottom chamber while the eyes of the user are situated in the top chamber, the partition including at least one passage arranged to allow fresh air to flow between the top chamber and the bottom chamber during a stage in which the user is breathing in; and a snorkel arranged to extend from a top portion of the body, the snorkel including at least one air duct, wherein the body includes an exhaled air exhaust device putting the bottom chamber into fluid-flow connection with the air duct of the snorkel, and wherein the exhaled air exhaust device includes at least a first check valve arranged between the bottom chamber and the exhaled air exhaust device to allow exhaled air from the bottom chamber to flow towards the air duct of the snorkel during a stage in which the user is breathing out, the first check valve being closed during the stage in which the user is breathing in. 2. The diving mask according to claim 1 , wherein the first check valve is arranged in the bottom chamber. 3. The diving mask according to claim 1 , wherein the first check valve is arranged in a bottom end portion of the exhaled air exhaust device. 4. The diving mask according to claim 1 , wherein the first check valve includes a flexible membrane. 5. The diving mask according to claim 4 , wherein the flexible membrane is constituted by a portion of the flexible skirt. 6. The diving mask according to claim 4 , wherein the first check valve includes a valve seat co-operating with the flexible membrane, the valve seat being integral with the faceplate. 7. The diving mask according to claim 4 , wherein the exhaled air exhaust device includes at least a first exhaled air exhaust channel extending along one of the side edges of the faceplate, the flexible skirt having a first side portion that covers the first exhaled air exhaust channel, wherein the first exhaled air exhaust channel includes a bottom end portion having at least one opening opening out into the bottom chamber, wherein the first check valve is arranged to close said opening during the stage in which the user is breathing in, and wherein the flexible membrane is situated inside the first exhaled air exhaust channel, in register with said opening. 8. The diving mask according to claim 1 , wherein the exhaled air exhaust device includes at least a first exhaled air exhaust channel extending along one of the side edges of the faceplate, the flexible skirt having a first side portion that covers the first exhaled air exhaust channel. 9. The diving mask according to claim 8 , wherein the first exhaled air exhaust channel is integral with the faceplate. 10. The diving mask according to claim 8 , wherein the first exhaled air exhaust channel includes a bottom end portion having at least one opening opening out into the bottom chamber, and wherein the first check valve is arranged to close said opening during the stage in which the user is breathing in. 11. The diving mask according to claim 8 , wherein the exhaled air exhaust device further includes a second exhaled air exhaust channel and a second check valve arranged to allow exhaled air from the bottom chamber to flow towards the air duct of the snorkel during the stage in which the user is breathing out, the second check valve being closed during the stage in which the user is breathing in. 12. The diving mask according to claim 1 , wherein the snorkel includes a single air duct that is in fluid-flow communication with the bottom chamber and with the top chamber. 13. The diving mask according to claim 1 , wherein the partition includes at least one check valve arranged to allow fresh air from the top chamber to flow towards the bottom chamber only during the stage in which the user is breathing in. 14. The diving mask according to claim 13 , wherein the check valve includes a flexible flap constituted by a portion of the flexible skirt. 15. A diving mask, comprising: a body having a faceplate and a flexible skirt, said flexible skirt including a partition separating a top chamber for vision from a bottom chamber for breathing, the partition being arranged to bear on the nose of a user so that the mouth and nose of the user are situated in the bottom chamber while the eyes of the user are situated in the top chamber, the partition including at least one passage arranged to allow fresh air to flow between the top chamber and the bottom chamber during a stage in which the user is breathing in; and a snorkel arranged to extend from a top portion of the body, the snorkel including at least one air duct, wherein the body includes an exhaled air exhaust device putting the bottom chamber into fluid-flow connection with the air duct of the snorkel, wherein the exhaled air exhaust device includes at least a first check valve arranged to allow exhaled air from the bottom chamber to flow towards the air duct of the snorkel during a stage in which the user is breathing out, the first check valve being closed during the stage in which the user is breathing in, and wherein the first check valve is arranged in the bottom chamber. 16. A diving mask, comprising: a body having a faceplate and a flexible skirt, said flexible skirt including a partition separating a top chamber for vision from a bottom chamber for breathing, the partition being arranged to bear on the nose of a user so that the mouth and nose of the user are situated in the bottom chamber while the eyes of the user are situated in the top chamber, the partition including at least one passage arranged to allow fresh air to flow between the top chamber and the bottom chamber during a stage in which the user is breathing in; and a snorkel arranged to extend from a top portion of the body, the snorkel including at least one air duct, wherein the body includes an exhaled air exhaust device putting the bottom chamber into fluid-flow connection with the air duct of the snorkel, wherein the exhaled air exhaust device includes at least a first check valve arranged to allow exhaled air from the bottom chamber to flow towards the air duct of the snorkel during a stage in which the user is breathing out, the first check valve being closed during the stage in which the user is breathing in, and wherein the first check valve is arranged in a bottom end portion of the exhaled air exhaust device. 17. A diving mask, comprising: a body having a faceplate and a flexible skirt, said flexible skirt including a partition separating a top chamber for vision from a bottom chamber for breathing, the partition being arranged to bear on the nose of a user so that the mouth and nose of the user are situated in the bottom chamber while the eyes of the user are situated in the top chamber, the partition including at least one passage arranged to allow fresh air to flow between the top chamber and the bottom chamber during a stage in which the user is breathing in; and a snorkel, distinct from the body, arranged to extend from a top portion of the body, the snorkel including at least one air duct, wherein the body includes an exhaled air exhaust device in fluid flow communication with the bottom chamber to evacuate the exhaled air out of the body, and wherein the body includes at least a first check valve arranged in the exhaled air exhaust device
