Diving mask device, has air tank made of flexible material without elastic property, where air tank is communicated with water-tight compartment of mask by free circulation of air and by flexible tube

摘要

The device has an air tank (1) made of flexible material without elastic property. The air tank is communicated with a water-tight compartment (8) of a mask by free circulation of air and by a flexible tube (3) that is resistant to strong pressure. The tube is flexibly connected to the mask by a connection made of hard and non-compressible material. A connector mask (4) allows seal through a skirt (6) of a silicone mask making the device adaptable to all masks dives. The air tank exhibits arbitrary form fitted into a strip (7) of the mask.
