The disclosure relates to a diving mask, including: a mask having a breath cavity corresponding to a mouth and a nose of a user; a vent tube connected to the mask and provided with an inlet passage, the inlet passage communicating the breath cavity with external air; and an exhaust device communicating the breath cavity, the exhaust device including an exhaust fan configured to discharge air in the breath cavity into an external environment, thereby enabling the external air to flow into the breath cavity through the inlet passage.

A mounting system allows one or more accessories to be removably attached to a SCUBA demand regulator system. A clamp encircles a portion of an air hose subsystem, the clamp having a threaded screw extending therefrom. An accessory is threadably attached to this screw. An extender arm can be sandwiched between this attached accessory and the clamp such that the extender arm has a second threaded screw that threadably receives a second accessory thereonto. One accessory may be a buckle mount that has a mounting surface on one side and a threaded receiver that threadably attaches to one of the screws and is rotated thereonto via a lock down wheel rotatably disposed within the buckle mount. A buoyancy assist subsystem creates either neutral or positive buoyancy to the invention when accessories are mounted.

The present invention relates to a floatable breathing device. The floatable breathing device a head unit, a mask and a snorkel. The head unit general includes an ornamental shaped outer housing, an insulated housing positioned within the outer housing and having an ornamental shape and buoyant properties, and a head receiving section provided between the outer housing and the insulated housing and contoured to a human head. The mask extends from the outer housing, while the snorkel extends through and exits a portion of the head unit above a predetermined waterline.

A rotatable folding diving mask includes a mask, a snorkel, and an elastic binding strap. By connecting the snorkel and the mask through a rotating shaft and combining with the structural design of a control button, a rotating and folding structure is provided, and the operation is simple and it is easy to fold, thereby achieving the purpose of reducing the occupied space. The elastic binding strap is connected to the mask through a buckle connection structure, so that the elastic binding strap can be easily disassembled and replaced, and the structure is simple and ingenious.

A full face diving mask having a transparent visor (2), a frame or strapping (3), a sealing skirt (4) to ensure the water-tight seal, and suitable straps (5) for fitting the mask on the user's face. The mask has a breathing tube (6) which engages on the tipper part of the mask and which allows the flow of air to enter into the compartment made between the frame and the visor. The breathing tube is made with separate ducts for the air inhaled and exhaled and the inside of the mask is made with two compartments, an upper main compartment (26) and a lower oronasal compartment (7) separated by a separating wall.

The present utility model discloses a full face dive mask, comprising a facial mask, a head strap connected with the facial mask and a respiratory pipe connected with the facial mask, wherein the side surface of the upper end of the facial mask is provided with a guide rail, the side surface of the lower end of the respiratory pipe is provided with a fixing shaft slidably connected with the guide rail, and the respiratory pipe is pulled outwards along the guide rail and revolved to fold in the facial mask. The utility model is simple in structure, small in size for the respiratory pipe can be folded to place, easy to store and capable of guaranteeing smooth breathing of a user.

A diving helmet apparatus includes a diving helmet that is based on a 98.sup.th percentile anthropomorphic head form. The helmet is relatively smaller and lighter than convention diving helmets. The center-of-gravity and center-of-buoyancy of the helmet are co-located to reduce diver fatigue. The apparatus has unique neck dam latch devices that use cam mechanisms. The neck dam and the opening in the helmet that receives the diver's head both have a substantially oval shape that contributes to a significant reduction in the volume of the helmet. The apparatus also uses unique face mask latch devices. The neck dam and face mask latch devices allow a diver to easily secure and remove the helmet and face mask without the assistance of dive tenders.

The buckle of the swimming mask includes a front end portion attached to a connecting unit, a rear end portion including an insertion portion in which the head strap is inserted, and an intermediate portion between the front end portion and the rear end portion. The wound portion around which the head strap is wound in the reversible manner is disposed in the intermediate portion.

An eye protection system including a reservoir for containing a product, the reservoir securable to a strap of an eye protection system. A spout communicatively coupled to the reservoir, the spout for dispensing the product to a lens of the eye protection system while the reservoir is secured to the strap.
