Abstract
The dispenser has a fan and an insecticide in its cavity. Upon control signals from a controller in the 'in use' mode, the fan is started and shutters provided at an inlet and outlet are opened, while in the 'not in use' mode, the fan is stopped and the shutters are closed. When one of the individual timers is selected, the controller issues control signals at times specified by the individual timers within a time period previously specified by the main timer. When the dispenser is in the 'not in use' mode, the shutter isolates the cavity from the outside.
