Automatic intermittent vapor dispenser

A semistatic vapor dispenser comprising:

• static vapor generator means, adapted to generate vapors in a continuous manner, for providing an accumulation of vapors during a first given time interval;
• air circulating means, comprising a motor and fan, for dispensing said accumulated vapors in the form of vapor-laden air into a given space during a second given time interval;
• means for minimizing recirculation of said vapor-laden air through said vapor dispenser;
• said recirculation minimizing means comprising a set of intake louvers having their open slots directed upwardly, and a set of exhaust louvers having their open slots directed downwardly;
• and
• means, comprising electronic circuitry for deactivating said air-moving means during said first given time interval, and for activating said air-moving means during said second given time interval;
• said static vapor generator means comprising a gel body positioned in a receptacle that substantially confines the bottom and sides of the body;
• said gel body being positioned in contact with a syneresis pad;
• whereby liquid squeezed out of said gel body by syneresis is absorbed by said syneresis pad.

A vapor dispenser comprising:

• static vapor generator means for providing an accumulation of vapors during a first given time interval;
• air-moving means for dispensing said accumulated vapors into a given space during a second given time interval;
• and
• automatic means for intermittently deactivating and activating said air-moving means for said first and second time intervals to provide a plurality of dispensing cycles per hour of operation;
• said static vapor generator means comprising a gel body in a receptacle that substantially confines the bottom and sides of the body;
• said gel body comprising:
• a gelling agent;
• a coacting liquid system;
• a material portion of the liquids forming said liquid system being adapted for air treatment;
• means for improving the uniformity of the vaporization rate of said static vapor generator;
• said vaporization rate improving means comprising a syneresis pad whose exposed area increases as the exposed area of said gel body decreases;
• whereby the overall exposed area of said gel body and said syneresis pad tends to remain constant.
