Abstract
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 diving mask comprising:
- a rigid frame having a front perimeter edge and a rear perimeter edge, said rigid frame provided with an upper portion, a lower portion, and a first and a second lateral portion arranged to connect said upper portion to said lower portion;
- a visor made of a transparent material and engaged to said rigid frame, said visor being configured in such a way to protrude beyond said front perimeter edge of said rigid frame;
- an inhalation duct, or snorkel, integral to said upper portion of said rigid frame, said inhalation duct or snorkel being provided with a longitudinal passage;

- a one-way valve arranged to pneumatically connect said upper chamber with said lower chamber and configured to allow air to pass from said upper chamber to said lower chamber during an inspiration of the user, and to impede, instead, the air to pass in the opposite direction, that means from said lower chamber to said upper chamber during an expiration of the user;
- an exit mouth for the exit of the air breathed out by the user;
- a discharge duct configured to pneumatically connect said lower chamber with said exit mouth;
