A diving mask includes a transparent visor, a frame, a gasket to guarantee the watertight seal and appropriate belts for fitting the mask, a breathing tube associated with the facial part is fitted onto the upper part of the mask and which enables the flow of air to enter into the compartment between the frame and the visor. The path of air in the inhalation phase and in the exhalation phase both in the mask and tube are different from each other. The tube is made with separate ducts for inhalation and exhalation and the inside of the mask is made with two compartments, one upper front and one lower oronasal separated by a wall. The path provides that inhalation air is introduced by the tube into the frontal compartment and then into the oronasal one and air exhaled from the oronasal compartment travels up to the tube.

The present invention provides a retaining device for connecting a mask and a snorkel. The mask has a head strap and a positioning ring, and the head strap freely passes through the positioning ring. The retaining device comprises a male fastening element and a female fastening element, which is connected to the male fastening element. The male fastening element is connected to one of the positioning ring and the snorkel, and the female fastening element is connected to the other. The user may assemble or separate the mask and the snorkel with the retaining device of the present invention, and there wouldn't be relative linear displacement between the mask and the snorkel in use due to buoyancy and gravity.

The present invention provides a retaining device for connecting a snorkel and a mask. The retaining device comprises a snorkel fastening portion, a mask fastening portion, and a connecting portion. The snorkel fastening portion is provided on the snorkel. The mask fastening portion is provided on the mask. The connecting portion is formed between the snorkel fastening portion and the mask fastening portion. The snorkel fastening portion and the mask fastening portion form a distance therebetween substantially ranging from 1 mm to 50 mm, in which the connecting portion is capable of being resiliently deformed, thereby when a user wears the mask and contains a mouthpiece of the snorkel, the snorkel is adapted to be moved relative to the mask within a limited displacement.

A breathable mask includes a main body, a breathing tube, a head strap and a chin strap or support. The breathing tube can be in fluid communication with the interior of the main body. The head strap and a chin strap or support form a three-point fix from a user’s head to the main body of the mask.

Provided is a pool mask that can be used even in water in the field of swimming lessons, for example. The present invention provides a pool mask that, when worn by a user, forms a predetermined space between a main body part and at least a mouth of the user and is open downward so that the space communicates with an external space. To manufacture the pool mask, first, a right main body part and a left main body part that are formed of a polyvinyl chloride material are prepared. Next, an end of the right main body part and an end of the left main body part are sewed up together to form a central part. Finally, a strap part is attached to each of the other end of the right main body part and the other end of the left main body part.

A diving mask includes a mask module including a mask frame, a fixing base fixed to the mask frame and a camera support base. The camera support base is detachably mounted to the fixing base, which facilitates installation and removal of the camera. The fixing base includes a receiving space with an insertion opening, a first locking opening located at a side of the receiving space and a second locking opening located at an opposite side of the receiving space. The camera support base includes an insertion portion and an elastic portion extending from the insertion portion obliquely such that when the elastic portion passes over the insertion opening to be received in the receiving space, the elastic portion is capable of restoring to its original state to selectively engage in the first locking opening or the second locking opening, which allows the shooting direction of the camera to be adjustable.

A diving and snorkeling mask structure including a full face mask, a frame, at least one lens, a joint, a respiratory tube and at least one securing belt is disclosed. The full face mask includes a first soft material region connected with a second soft material region. The frame is combined with the second soft material region of the full face mask. The at least one lens is disposed in the frame. The joint is disposed on the full face mask, and adjacent to the upper side of the frame. The respiratory tube is disposed on the joint, and establishes the air communication with the full face mask via the joint. The at least one securing belt includes a side buckle element to snap fit the full face mask.

The present disclosure provides diving goggles, which include: a mask assembly, including a mounting hole, and a dismounting hole passing through a side wall of the mounting hole; a lens, installed in the mounting hole; a pressing ring, detachably embedded in one end of the mounting hole to fix the lens, the dismounting hole facing an outer peripheral wall of the pressing ring; and a detaching component, mounted on the mask assembly, one end of the detaching component passing through the dismounting hole and resisting against the outer peripheral wall of the pressing ring, for detaching the pressing ring from the mounting hole.

An ostomy pouching system is described. A baseplate includes a seal adapted to be securely placed on the skin about the perimeter of tissue defining a stoma incised into a patient. An ostomy reservoir forms a sealed space within which discharge can be received and held. A flex layer includes a seal that is airtight, watertight, or both, and which is structurally interposed between at least a portion of two or more of the skin, tissue, stoma, baseplate, and ostomy reservoir. The flex layer includes a resiliently and elastically malleable phase change material. The flex layer is deformable such that at least one portion of the flex layer can transmute the magnitude of a force applied to the flex layer and redirect the force. External forces acting upon at least one of the skin, tissue, stoma, baseplate, and ostomy reservoir are mitigated, transmuted, and isolated by the flex layer.

In a swimming mask, a skirt includes a circumferential wall in an annular shape extending rearward from a lens frame, and a seal portion disposed behind the circumferential wall to be brought into contact with a face of a wearer. The skirt also includes a high stiffness annular region disposed rearward apart from the lens frame, extending in both side regions and an upper region of a mask body, and having higher stiffness than stiffness of other part of the skirt.
