ABSTRACT:
A steam and air mixing chamber having a downwardly open housing is mounted on top of a steam generator located in a housing containing a water reservoir. A steam nozzle directs a jet of steam against a baffle mounted in the mixing chamber entraining air and forming a mist. Compressed air is directed into the mixing chamber by a venturi tube, thereby sucking in the mist and causing the mixture to flow into a breathing element. The vacuum and thus the vapor and mist temperature, are controlled by a shielding means which can be moved to overshadow a portion of venturi tube orifice, thereby diverting some of the airstream leaving the venturi tube.
