Ink vapor aerosol pen for pen plotters

Aerosol pen apparatus comprising:

• a) a chamber containing liquid ink;
• b) ultrasonic vaporizing transducer means disposed within said chamber for forming ink vapor from said liquid ink;
• c) a pen body having a nozzle tip;
• d) a conduit connected between said chamber and said pen body;
• e) pressure creating means for creating a pressure within said chamber sufficient to force said ink vapor through said conduit and out said nozzle tip;
• f) interrupter means disposed adjacent said nozzle tip for intercepting a steam of said ink vapor emitting by said nozzle tip when said interrupter means is in a first position and for not intercepting said stream of said ink vapor emitting by said nozzle tip when said nozzle tip when said interrupter means is in a second position;
• g) means for moving said interrupter means between said first position and said second position;
• and,
• h) ink vapor condensation removal means for removing condensed ink vapor from the interior of at least one of said conduit, pen body, and nozzle tip.

An aerosol pen comprising:

• a) a chamber containing liquid ink;
• b) ultrasonic vaporizing transducer means disposed within said chamber for forming ink vapor from said liquid ink;
• c) a pen body having a nozzle tip, said nozzle tip includes means for converging a stream of emitted ink vapor to a pre-established focal point, said nozzle tip being of a material which absorbs and recovers droplets of said ink vapor condensed therein and having an interior surface which is smooth and highly polished having no protrusions or irregularities whereby ink aerosol vapor resists condensing thereon;
• d) a conduit connected between said chamber and said pen body;
• e) pump means for creating a pressure within said chamber sufficient to force said ink vapor through said conduit and out said nozzle tip;
• f) interrupter means disposed adjacent said nozzle tip for intercepting a stream of said ink vapor emitting by said nozzle tip when said interrupter means is in a non-writing position and for not intercepting said stream of said ink vapor emitting by said nozzle tip when said interrupter means is in a writing position;
• g) means for moving said interrupter means between said non-writing position and said writing position;
• h) recycling means connected to said interrupter means for receiving said stream of said ink vapor emitting by said nozzle tip when said interrupter means is in said first position and for conducting absorbed ink vapor back to said chamber whereby said interrupter means acts as a valve for said stream of said ink vapor emitting by said nozzle tip;
• i) first wicking means disposed within said conduit for absorbing condensed ink vapor within said conduit, for conducting a first portion of condensed ink vapor back to said chamber by gravity, and for conducting a second portion of condensed ink vapor toward said pen body by gravity;
• and,
• j) second wicking means connected between said pen body and said recycling means for conducting said second portion of condensed ink vapor to said recycling means.
