Abstract

A full-face diving mask includes a mask and a breathing tube. The mask includes an outer frame, a lens housing and a fitting mask. The fitting mask includes a partition plate. The partition plate and the inner surface of the lens housing define an observation chamber on the top and a breathing chamber below. The partition plate includes at least one air intake port to allow inhaled air to be guided and circulated through at least one air intake passageway from the observation chamber toward the breathing chamber. The breathing chamber is further provided with an air compartment partition plate connected to the partition plate to define an air discharge compartment. The air compartment partition plate is provided with at least one air discharge port to allow exhaled air to be guided through at least one air discharge passageway from the air discharge compartment and discharged along the breathing tube.

Claims

1. A full-face diving mask, comprising:

a lens housing and a fitting mask sealed together at an interface;

wherein the lens housing includes a lens that is at least partially transparent;

a cavity formed by the lens housing and the fitting mask, the fitting mask including a face opening for the placement of a portion of a user'"'"'s face therethrough and into the cavity, wherein the face opening is configured to seal against the portion of the user'"'"'s face and prevent water from entering the cavity when the full-face diving mask is worn;

a first partition plate dividing the cavity between an upper air compartment located adjacent to the user'"'"'s eyes and a lower air compartment located adjacent to the user'"'"'s nose and mouth when the full-face diving mask is worn;

at least one valve located on the first partition plate permitting the transfer of air from the upper air compartment to the lower air compartment and preventing the transfer of air from the lower air compartment to the upper air compartment;

a second partition plate dividing the lower air compartment into a front lower air compartment located between the second partition plate and the lens housing and rear lower air compartment located between the second partition plate and the face opening; and

at least one additional valve located on the second partition plate permitting the transfer of air from the rear lower air compartment to the front lower air compartment and preventing the transfer of air from the front lower air compartment to the rear lower air compartment.

2. The full-face diving mask according to claim 1, further including a breathing tube connected at a first end thereof to at least one of the lens housing and the fitting mask and extending to a breathing tube opening located at a second end thereof.

3. The full-face diving mask according to claim 2, further including an air intake passageway extending between the breathing tube opening and the upper air compartment for permitting air intake and an air discharge passageway extending between the front lower air compartment and the breathing tube opening for permitting air discharge.

4. The full-face diving mask according to claim 3, wherein the lens housing is surrounded by a lens housing peripheral edge, wherein the fitting mask is surrounded by a fitting mask peripheral edge, and wherein the interface between the lens housing and the fitting mask is adjacent to both peripheral edges.

5. The full-face diving mask according to claim 4, wherein the air discharge passageway includes at least one air discharge conduit that extends adjacent to the interface from the front lower air compartment to the breathing tube.

6. The full-face diving mask according to claim 5, wherein the air intake passageway includes at least one air intake channel extending along the breathing tube and in fluid communication with the upper air compartment, and the air discharge passageway further includes at least one air discharge channel extending along the breathing tube and in fluid communication with the at least one air discharge conduit.

7. The full-face diving mask according to claim 6, wherein the at least one air discharge conduit comprises:

a first conduit section extending in a clockwise direction from the front lower air compartment and along the interface to the breathing tube; and

a second conduit section extending in a counterclockwise direction from the front lower air compartment and along the interface to the breathing tube.

8. The full-face diving mask according to claim 7, wherein the at least one air discharge channel in the breathing tube comprises:

a first discharge channel section in fluid communication with the first conduit section; and

a second discharge channel section in fluid communication with the second conduit section.

9. The full-face diving mask according to claim 6, wherein at least one of the lens housing and the fitting mask includes a connecting sleeve for selectively coupling to the breathing tube.

10. The full-face diving mask according to claim 9, wherein the connecting sleeve comprises:

an intake connector section for coupling the at least one air intake channel of the breathing tube to the upper air compartment; and

at least one discharge connector for coupling the at least one air discharge channel in the breathing tube to the at least one air discharge conduit.

11. The full-face diving mask according to claim 10, further including a sealing ring located between the connecting sleeve and the breathing tube

12. The full-face diving mask according to claim 3, wherein the breathing tube includes an adjustment device located adjacent to the breathing tube opening and for preventing fluid from entering the air intake passageway and the air discharge passageway when the breathing tube opening is under water.

13. The full-face diving mask according to claim 12, wherein the adjustment device comprises:

a first floater member located adjacent to an entry control point of the air intake passageway, the first floater member sealing the entry control point when it is underwater and is displaced away from the entry control point when it is not underwater to permit air to travel therethrough; and

a second floater member located adjacent to an exit control point of the air discharge passageway, the second floater member sealing the exit control point when it is underwater and is displaced away from the exit control point when it is not underwater to permit air to travel therethrough.

14. The full-face diving mask according to claim 13, wherein the adjustment device further comprises:

a sealing plate and an end cap coupled together;

wherein the sealing plate is located between the breathing tube opening and the end cap, and the sealing plate defines a first hole for the entry control point sized to seal against the first floater member and a second hole for the exit control point sized to seal against the second floater member.

15. The full-face diving mask according to claim 14, wherein the floater members are seated in a caged portion that is positioned to overlap at least a portion of the air intake passageway and the air discharge passageway, and wherein the caged portion defines a series of slots forming the breathing tube opening.

16. The full-face diving mask according to claim 15, wherein the sealing plate and end cap couple the air intake passageway and the air discharge passageway to the breathing tube opening through the first hole and the second hole.

17. The full-face diving mask according to claim 16, wherein the air discharge passageway includes a second exit control point and the adjustment device further comprises a third hole and a third floater member.

18. The full-face diving mask according to claim 17, wherein the first floater member is larger than either of the second floater member or the third floater member.

19. The full-face diving mask according to claim 18, wherein the first floater member is located between and directly connected to the second floater member and the third floater member such that each of the floater members move within the caged portion together.

20. The full-face diving mask according to claim 1, wherein the lens housing includes a valve permitting accumulated water in the rear lower air compartment to be discharged into the environment but preventing water in the environment from entering the rear lower air compartment.
