Diving mask including a snorkel with a valve, the valve including a valve orifice configured to allow fluid circulation between an outside of the snorkel and an inside of the snorkel, and a valve closure member, which can move between an open position in which the valve orifice is open and a closed position in which the valve orifice is closed by the valve closure member, wherein the mask includes a balancing means for limiting a pressure difference between the internal pressure of the mask and the external pressure, the balancing means being configured to allow fluid circulation between the outside of the mask and the inside of the mask when the mask is used by a user and when the closure member is in the closed position.

A diving mask having a rigid frame with a front perimeter edge and a rear perimeter edge. The frame provides an upper portion and a lower portion connected by first and second lateral portions. The mask also includes a visor of a transparent material and fixed to the frame, and an inhalation duct, or snorkel. Inside the frame a face member made of a soft and flexible material is arranged in contact with the user's face. A partition member divides the volume between the visor and the face member in an upper chamber pneumatically connected to the inhalation duct, or snorkel, through an opening, and in a lower chamber arranged to house the nose and the mouth of the user. A discharge duct pneumatically connects the lower chamber with an exit mouth.

A breathable mask includes a body having a main frame, a lens, and a waterproof sealing skirt. The waterproof sealing skirt has a partition dividing the interior of the body into an upper chamber that shields the eyes and a lower chamber that shields the nose, and arranges independent air intake passages and exhaust passages to separate the fresh air inhaled and the dirty air exhaled. Alternatively, a nasal connecting portion having a purge valve can be provided in fluid communication with the lower chamber. It is also possible to provide a three-way connector having a nasal connecting portion, a mouth portion, and a drain portion in fluid communication with one another, wherein the nasal connecting portion is in fluid communication with the lower chamber. The mouth connecting portion is adapted to be contained in the user's mouth when the user well wears the breathable mask.

The disclosure relates to a diving mask comprising a body having a faceplate and a flexible skirt, and a snorkel extending a top portion of the body. The body includes an exhaled air exhaust device that puts the bottom chamber in fluid-flow connection with the air duct of the snorkel. The exhaled air exhaust includes at least a first check valve arranged to allow exhaled air from the bottom chamber to flow towards the air duct of the snorkel during a stage in which the user is breathing out, the first check valve being closed during a stage in which the user is breathing in.

A breathable mask including a breathing tube and a body is provided. The body is connected to the breathing tube so that an interior of the body is in fluid communication with an outside through the breathing tube. The body includes a main frame, a lens, a waterproof skirt, a purge valve and a mouthpiece. The waterproof skirt has a portion embedded in the main frame and a partition to divide the interior of the body into an upper chamber and a lower chamber. The purge valve is disposed at a lower portion of the body and in one-way fluid communication with the lower chamber. The mouthpiece disposed in the lower chamber has a first end and a second end opposite to the first end. The first end is contained in a mouth of the user and the second end is in fluid communication with the purge valve.
