Tobacco smoking apparatus

Abstract

The invention provides a tobacco smoking apparatus that enables a person to smoke; namely, inhale and exhale smoke and other combustion products from burning tobacco, while isolating and protecting others from a substantial portion of the combustion products, including smoke, smoker's exhale, and odor, that are produced from smoking tobacco.

1 . A tobacco smoking apparatus for use in smoking a cigarette, said tobacco smoking apparatus comprising:
 an enclosure that is configured for enclosing tobacco combustion activity;   wherein said tobacco smoking apparatus is configured so that a user can both inhale combustion products from said enclosure and exhale combustion products into said enclosure;   an air input port that is configured to input atmospheric gases residing outside of said enclosure when an internal gas pressure of internal gases residing inside of said enclosure is less than an atmospheric pressure of said atmospheric gases residing outside of said enclosure by a sufficient negative pressure value; and   a gas output port that is configured to output internal gases and other combustion products residing inside of said enclosure when an internal gas pressure of said internal gases residing inside said enclosure is greater than said atmospheric pressure by a sufficient positive pressure value;   wherein said tobacco smoking apparatus includes a movable cigarette holder for holding a cigarette, said tobacco smoking apparatus being configured so that a user of said tobacco smoking apparatus can manually move said moveable cigarette holder between a first position and a second position, wherein said cigarette holder when in said first position holds said cigarette so that a front end of said cigarette extends to a position external to said enclosure, wherein said cigarette holder when in said second position holds said cigarette so that said cigarette is entirely enclosed within said enclosure, wherein said tobacco smoking apparatus is configured so that said movable cigarette holder holds a cigarette within said enclosure, and wherein said enclosure includes a port for use in inhaling combustion products, said tobacco smoking apparatus being configured so that when said movable cigarette holder is in said second position, a back end of said cigarette is closer to said port for use in inhaling than when in said first position.   
     
     
         2 . The tobacco smoking apparatus of  claim 1 , wherein said tobacco smoking apparatus includes a tubular structure extending from said movable cigarette holder for directing combustion products from said movable cigarette holder toward said port for use in inhaling. 
     
     
         3 . The tobacco smoking apparatus of  claim 1 , wherein said movable cigarette holder is configured to be slid between said first position and said second position. 
     
     
         4 . The tobacco smoking apparatus of  claim 1 , wherein said air input port has an outside portion that is pivotable between an open position and a closed position. 
     
     
         5 . The tobacco smoking apparatus of  claim 1 , wherein said tobacco smoking apparatus is configured so that said atmospheric gases are input through said air input port responsively to said user inhaling said combustion products. 
     
     
         6 . The tobacco smoking apparatus of  claim 1 , wherein said tobacco smoking apparatus is configured so that said internal gases are output from said enclosure responsively to said user exhaling said combustion products. 
     
     
         7 . The tobacco smoking apparatus of  claim 1 , wherein said tobacco smoking apparatus includes a rod that can extend to an exterior of said enclosure, the smoking apparatus being configured so that said user can move said movable cigarette holder by pulling or pushing said rod. 
     
     
         8 . The tobacco smoking apparatus of  claim 1 , wherein said movable cigarette holder is sized to hold said cigarette via a “snug fit” type of engagement. 
     
     
         9 . The tobacco smoking apparatus of  claim 1 , wherein said movable cigarette holder is configured so that said cigarette can be held by said movable cigarette holder by way of a user pressing said cigarette into said movable cigarette holder.
