Air-blowing system having discharge device

An air-blowing system comprising:

• an air supply passage having an air outlet from which air is blown off and an air inlet;
• a discharge device provided for generating active ingredients and disposed outside the air supply passage;
• and
• an introducing pipe having a first end connected to the discharge device and disposed outside the air supply passage, and a second end disposed in the air supply passage, the introducing pipe being provided for introducing the active ingredients into the air supply passage,
• wherein the second end of the introducing pipe includes an opening face, and
• the introducing pipe is arranged such that, in a state where the second end of the introducing pipe is disposed in the air supply passage between the air inlet and the air outlet, the opening face and a main stream direction of an air flow which flows through the air supply passage at a predetermined point of the opening face are substantially parallel to each other.
