<p>PURPOSE:To enable a person to smoke a cigarette while sitting on a chair at a desk, not to contaminate surrounding environment and not to hinder another person. CONSTITUTION:A cigarette smoke discharging disposal chamber 2 is fixed to a desk 1. Filters 3, 4 and a circulation fan 5 are disposed in the smoke discharging disposal chamber 2. Clean air passed through the filters 3, 4 is discharged upwardly from nozzles 9, 9, 9 and 9 above the desk 1 to guide surrounding air so as to generate a swirl. An artificial tornade is produced at a negative pressure region generated in the discharging hood 11 disposed at an upper surface of the desk 1 and with the swirl. The air is purified by the filters 3, 4 while the cigarette smoke or irritating smell is sucked into the artificial tornade.</p> |
