A SWIM GOGGLES HEADWEAR AND COSTUME SYSTEM WITH A COSTUME SWIM MASK, HAVING A MASK ELEMENT ATTACHED TO AT LEAST ONE COSTUME ELEMENT, AND AT LEAST ONE INTEGRATED GOGGLES, EYEWEAR, AND/OR LENSES ELEMENT providing under water vision with a water-tight sealing portion or mechanism securing the eyepieces around the eye area of a user during use of the goggles and a material or fabric costume mask element conducive to being worn by a child or adult and to even help in aiding the process of learning to swim.

A snorkel is provided. The snorkel has a mouthpiece portion and a waterproof structure which is disposed at an end opposite to the mouthpiece portion. The waterproof structure has a tube body and a lid body. At least one vent and a first stopper are disposed at the tube end portion of the tube body. The lid body has an opening and a second stopper. The tube end portion is provided within the lid body by passing through the opening. When the waterproof structure is located above the water, the waterproof structure is in fluid communication with the mouthpiece portion by the opening and the vent. When the waterproof structure is located below the water, the lid body is floated upwards so that the second stopper contacts with the first stopper portion to substantially block flow of the water from the opening into the vent of the tube body.

A system to prevent water from entering a snorkel breather tube includes a tube, wherein the tube is attached to a snorkel body and a pressure device, wherein the pressure device is attached to the tube at a tube tip. The pressure device comprises an air passage channel extending through an internal portion of the pressure device and an output hole, the output hole enabling entry of air into the air passage channel while preventing water from entering when the equipment of the system is submerged.

A breathable mask and a body thereof are provided. The body includes a main frame, a lens and a waterproof skirt. The waterproof skirt has a partition which divides the interior of the body into an upper chamber and a lower chamber. When the user wears the breathable mask, the partition is seated above the user's nose, the user's eyes are accommodated in the upper chamber, and the user's nose and mouth are accommodated in the lower chamber. The waterproof skirt also includes a bridge disposed across the lower chamber and divides the lower chamber into a nasal chamber and a mouth chamber below the nasal chamber. The bridge has an opening and an orinasal one-way valve adjacent to the opening. The orinasal one-way valve only allows a unidirectional fluid communication from the nasal chamber to the mouth chamber.

A breathable mask and a body thereof are provided. The body includes a main frame, a lens assembly embedded within the main frame, a waterproof skirt with a partition dividing the interior of the body into upper and lower chambers, and an exhaust passage. When a user wears the breathable mask, the partition is seated above the user's nose, with the eyes accommodated in the upper chamber, and the nose and mouth in the lower chamber. The exhaust passage communicates with the lower chamber and has a collapsible zone with an inner portion and an outer portion having an identifiable mechanism exposed to the outside so that when the user's finger presses the outer portion through the identifiable mechanism, the outer portion is suitably deformed inward and abutted against the inner portion to temporarily obstruct a fluid communication of the exhaust passage with the outside.

The breathing port isolation apparatus includes a housing, valve, and actuator to enable a diver to isolate a breathing port of a snorkel or dive regulator using a single mouthpiece. The housing is configured to seat the valve and actuator and releasably engage a mouthpiece and dive regulator, which provides the diver with a continuous flow of air through the mouthpiece without having to transition between multiple regulators or breathing ports. The valve includes a piston and enables linear movement between the first and second port. The actuator enables the diver to depress a push-button and transition the actuator between depressed and extended positions, which correspond to the first and second breathing ports.

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.

A breathing device for divers that includes a breathing tube exhibiting an end having an inclined opening, an obturator that is mobile between an open position and a closed position of the opening of the end, a float that activates the obturator, a first articulator that communicates the obturator to the tube, a second articulator that communicates the float to the tube. The first and the second articulators can each exhibit a respective hinge axis to the tube. The hinge axis to the tube of the second articulator can be more greatly distanced from the end of the tube relative to the hinge axis to the tube of the first articulator.

A breathing device for divers comprises a mouthpiece and a rigid breathing tube with a first end featuring an inclined opening, and a second end connected to a joint of the mouthpiece, a movable shutter that can move between an open and a closed position of the opening of the first end, a float for actuating the shutter, first articulation means for connecting the shutter to the tube, and second articulation means for connecting the float to the tube wherein the breathing tube is formed from a single tubular piece, externally to which the first and second articulation means are positioned.
