This disclosure describes a full-face type mask for underwater use. The mask is provided with a mouthpiece to enable the wearer to breathe with his/her head under the surface of the water. The mask is also provided with a communication device.

A full-face snorkel mask includes a mask assembly having a breathing chamber and a snorkel assembly having a fresh air intake channel and an exhaust air discharging channel. The fresh air intake channel guides fresh air into the breathing chamber and the exhaust air discharging channel discharges waste air from the breathing chamber. During snorkeling, fresh air is supplied via the fresh air intake channel to the breathing chamber for a user and the waste air exhaled from the user is discharged from the breathing chamber to the exhaust air discharging channel. Therefore, fresh air is separated from the waste air to prevent the user from repeatedly inhaling the waste air in the breathing chamber.

The mask for surface snorkeling comprises a rigid frame (2), a transparent visor (3), a soft face mask (4) applicable in an airtight way to the face of the user and having a membrane (7) which delimits an upper viewing chamber (8) being shaped to contain the eyes of the user and a lower breathing chamber (9) being shaped to contain the nose and mouth of the user, and a breathing circuit (5) connected to the lower chamber (9), a ventilation circuit of the upper chamber (8) independent and separated from the breathing circuit (5) also being provided.

A full face mask and snorkel can include a full face mask and a rigid snorkel attached to the side of the mask. The side location of the ridged snorkel avoids peripheral ducting of air around the full face mask. The full face mask includes a main peripheral full face seal coupled to the mask's rigid support structure. The full face mask includes a separation seal dividing the full face mask into at least an upper chamber. The snorkel is affixed to the side of the full face mask at a location proximate to where the separation seal meets the main seal. A full face mask and snorkel can also include an exhalation valve located within the snorkel and proximate to the mask so as to avoid a volume of respirated air within the snorkel from being reinhaled into the lower chamber of the full face mask.

The present disclosure discloses a diving mask, including a mask assembly and a breather assembly. The mask assembly is provided with an accommodating cavity and a first air outlet channel. The first air outlet channel is arranged along a circumferential direction of the accommodating cavity. A wall surface of the accommodating cavity is provided with a first air inlet and an air outlet. The first air outlet channel is communicated with the accommodating cavity through the air outlet. The breather assembly is provided with an air inlet channel and a second air outlet channel which are spaced from each other. The air outlet is communicated with the second air outlet channel. The air inlet channel is communicated with the first air inlet.

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.

Mask of the so-called full face type comprising a transparent visor (2), a frame or strapping (3), a sealing skirt (4) preferably made of rubber designed to ensure the water-tight seal and suitable straps (5) for fitting the mask on the face. The face part of the mask is associated with breathing tube (6) which engages on the upper part of the mask and which allows the flow of air to enter into the compartment made between the frame and the visor.

The path of the air being inhaled and exhaled both in the mask and in the breathing tube are different from each other, the 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 front compartment (6) and a lower oronasal compartment (7) separated by a separating wall.

The path inside the mask is such that the inhaled air is introduced from the tube in the front compartment and then in the oronasal compartment and the air exhaled from the oronasal compartment travels on a perimetric path of the mask up to the tube.

A breathable mask for snorkeling is provided, which includes a body and an intake conduit in fluid communication with the body's interior. The body includes a main frame, a viewing window, a waterproof skirt, an intake passage and a drain valve. The waterproof skirt has a partition dividing the interior into an upper chamber configured to accommodate a user's eyes only and a lower chamber configured to accommodate the user's nose only. The intake passage is only formed between the intake conduit and the lower chamber, and provided with a one-way valve for fresh air from outside unidirectionally flowing through the intake passage and entering the lower chamber. The drain valve is provided at a lower portion of the body so that air exhaled from the user's nose is capable of being limited to be unidirectionally discharged outwards from the lower chamber through the drain valve only.
