Hookah

Abstract

The present invention includes a check valve on or about the stem of hookah that re-directs wetted smoke through the conduit that primarily supplies dry smoke into a hookah bottle.

What is claimed is: 
     
         1 . A hookah comprising:
 a hookah bottle having a solid sidewall defining a bottle interior and a bottle neck;   a hookah stem releasably affixable to said hookah bottle, said stem comprising:
 a primary stem, positioned above said bottle neck, adapted to hold a hookah burner and defining: a central, substantially-vertical dry smoke conduit bounded by a dry smoke inlet and a lower dry smoke outlet formed by a transverse stem wall; and a wet smoke conduit bounded by a wet smoke inlet and a peripheral wet smoke outlet above said bottle neck; 
 a down tube, affixed to said dry smoke outlet and further defining said dry smoke conduit, terminating in a lower dry smoke release aperture, dimensioned to extend into said hookah bottle to a penetration depth at least half of a bottle height; 
   a pressure-actuated check valve, positioned upon said primary stem and in gaseous communication with said bottle interior, with a wet smoke entry exposed to said bottle interior and a wet smoke intake in direct gaseous communication with said dry smoke inlet, and adapted to selectively impede, during neutral and negative bottle pressure events, and allow, during positive bottle pressure events, gaseous communication from said wet smoke entry to said wet smoke intake; and   a hose fitting, affixed to said wet smoke outlet, for the releasable affixation of a hookah hose to said hookah stem.   
     
     
         2 . The hookah of  claim 1  wherein said wet smoke intake includes an external pressure conduit. 
     
     
         3 . The hookah of  claim 2  wherein said wet smoke intake is positioned above said down tube and below said dry smoke inlet. 
     
     
         4 . The hookah of  claim 1  wherein said check valve includes a movable impediment. 
     
     
         5 . The hookah of  claim 4  wherein said check valve includes a removable case exposing said movable impediment. 
     
     
         6 . The hookah of  claim 1  wherein said stem includes universal hose fittings, and wherein said check valve is adapted to removable affix to said universal hose fittings. 
     
     
         7 . The hookah of  claim 7  wherein said check valve includes an external pressure conduit, and wherein said primary stem includes a radial wet smoke inlet in gaseous communication with said dry smoke inlet. 
     
     
         8 . The hookah of  claim 7  wherein said external pressure conduit is flexible. 
     
     
         9 . A hookah comprising:
 a hookah bottle having a solid sidewall defining a bottle interior and a bottle neck;   a hookah stem releasably affixable to said hookah bottle, said stem comprising:
 a primary stem, positioned above said bottle neck, adapted to hold a hookah burner and defining: a central, substantially-vertical dry smoke conduit bounded by a dry smoke inlet and a lower dry smoke outlet formed by a transverse stem wall; and a wet smoke conduit bounded by a wet smoke inlet and a peripheral wet smoke outlet above said bottle neck; 
 a down tube, affixed to said dry smoke outlet and further defining said dry smoke conduit, terminating in a lower dry smoke release aperture, dimensioned to extend into said hookah bottle to a penetration depth at least half of a bottle height; 
 a pressure-actuated check valve with a wet smoke entry, within said primary stem, exposed to said bottle interior and a wet smoke intake, within said primary stem, in direct gaseous communication with said dry smoke inlet, and adapted to selectively impede, during neutral and negative bottle pressure events, and allow, during positive bottle pressure events, gaseous communication from said wet smoke entry to said wet smoke intake; and 
 a hose fitting, affixed to said wet smoke outlet, for the releasable affixation of a hookah hose to said hookah stem. 
   
     
     
         10 . The hookah of  claim 9  wherein said check valve includes said wet smoke intake directly contacting said dry smoke inlet of said primary stem. 
     
     
         11 . The hookah of  claim 10  wherein said check valve includes said wet smoke entry directly contacting said bottle interior through said primary stem. 
     
     
         12 . The hookah of  claim 11  wherein said check valve includes a physical, movable impediment that dislocates to provide access between said dry smoke inlet and said wet smoke entry during said positive pressure event. 
     
     
         13 . The hookah of  claim 9  wherein said check valve is embedded within said plenum to include a substantially vertical wet smoke entry that, in positive pressure, events is in gaseous communication with a substantially horizontal wet smoke intake. 
     
     
         14 . The hookah of  claim 13  wherein said wet smoke intake accesses said dry smoke conduit above said down tube.
