Abstract
A cold weather breathing device comprises a mouthpiece, a valve unit containing first and second valves in air communication with the mouthpiece and a conduit (preferably flexible) extending downwardly from the valve unit. The first valve in the valve unit provides air communication between the conduit and the mouthpiece when the user inhales, and blocks said air communication when the user exhales. A second valve in the valve unit provides air communication between the mouthpiece and an exhaust opening of the valve unit when the user exhales, and for blocking such air communication when the user inhales. Further provided is a shield unit including a substantially air impervious member coupled to an end of the conduit remote from the mouthpiece, and a plurality of projections extending from the air impervious member for spacing the air impervious member from a body portion of the user so as to provide at least one air passage between the air impervious member and the surface of the user against which the projections are adjacent, the at least one air passage being in air communication with the interior of the conduit. In this manner, body heat is used to effectively heat the air being inhaled by the user via the air passage(s), conduit and valve unit.
