Chemical diffusion system, chemical diffusion apparatus, chemical diffusion unit and chemical cartridge

摘要

A chemical diffusion apparatus ( 1 ) comprises a first tank ( 2 ) filled up with a volatile chemical A such as a communication disturbance agent and a second tank ( 3 ) filled up with a volatile chemical B. The chemicals A and B are sucked by means of a discharge volume variable pump ( 6 ) to be discharged onto an evaporating dish ( 8 ) through a discharge tube ( 7 ). A mixed chemical C discharged onto the evaporating dish 8 is naturally diffused in the air. A control circuit ( 9 ) controls drive of the pump ( 6 ). An input side of the control circuit ( 9 ) is connected to a timer ( 11 ) and an environment parameter detecting means such as a temperature sensor ( 12 ), an illumination sensor ( 13 ), a wind direction sensor ( 14 ) and a wind velocity sensor ( 15 ). The control circuit ( 9 ) controls discharge and discharge volume of the mixed chemical C from the pump ( 6 ) on the basis of detecting results from the respective sensors in accordance with a control program.
