Chair with negative ion generator

Abstract

A chair or similar article of furniture having an embedded negative ion generation device to clean the airspace around the chair. The negative ion generation device may be positioned within the headrest or similar portion of the furniture to provide the air purification while maintaining the aesthetic appeal of the piece furniture which would be marred by an externally mounted system.

1 . A chair system comprising: 
 a chair comprising a support surface designed to support a person's body position;    a negative ion generator positioned within the chair; and    an airflow system to draw air into the negative ion generator through an intake port and direct the air to an exhaust port remote from the intake port.    
     
     
         2 . The chair system of  claim 1  wherein the support surface comprises a seating portion and a backrest.  
     
     
         3 . The chair system of  claim 2  wherein the negative ion generator is positioned within the backrest.  
     
     
         4 . The chair system of  claim 1 , wherein the airflow system comprises: 
 a fan to facilitate airflow through the negative ion generator.    
     
     
         5 . The chair system of  claim 1 , wherein the negative ion generator further comprises: 
 a transformer to generate a high voltage across an air gap to ionize air passing through the gap.    
     
     
         6 . The chair system of  claim 1 , further comprising: 
 a compressible pillow to generate airflow through movement of a user.    
     
     
         7 . The chair system of  claim 1 , wherein the negative ion generator operates on one of a 120 volt alternating current and a 5 to 50 volt direct current.  
     
     
         8 . The chair system of  claim 1 , wherein the airflow system further comprises: 
 air ducting to be disposed within the chair to fluidly connect the negative ion generator to the exhaust port.    
     
     
         9 . The chair system of  claim 1 , a high voltage grid defining a 4 mm to 20 mm space for air to pass through.  
     
     
         10 . An article of furniture comprising: 
 a first portion comprising surfaces adapted to support a human body;    a negative ion generator substantially enclosed within the first portion; and    a compressible structure to generate airflow through the negative ion generator using movement of a user seated on the first portion.    
     
     
         11 . The article of furniture of  claim 10 , further comprising: 
 an air duct system providing fluid communication between the negative ion generator and an exhaust port placed at a distance from the negative ion generator.    
     
     
         12 . The article of furniture of  claim 10 , wherein the negative ion generator further comprises: 
 an ion grid array to produce a voltage greater than 120 volts across an air gap.    
     
     
         13 . The article of furniture of  claim 10 , wherein the compressible structure is a pillow.  
     
     
         14 . The article of furniture of  claim 10 , further comprising: 
 a fan to facilitate air flow through the negative ion generator.    
     
     
         15 . The article of furniture of  claim 10 , wherein the negative ion generator is disposed within a headrest.  
     
     
         16 . The article of furniture of  claim 10 , wherein the first portion is a chair.  
     
     
         17 . The article of furniture of  claim 10 , further comprising: 
 an air intake port positioned in a back of the article of furniture.    
     
     
         18 . The article of furniture of  claim 11 , wherein the air duct system directs air toward an outer edge of a headrest.
