PURPOSE: A cleaner attachment type injecting device is provided to inject substances for freshening and sterilizing air by using the air discharged through an exhaust port without separate power. CONSTITUTION: A cleaner attachment type injecting device comprises a body (20), a fixing unit (50), a gasket (211), a storage tank (30), and an injection unit (40). The fixing unit is hung on a grill formed on the exhaustion port of a cleaner so that the body is mounted on the cleaner to be detachably. The gasket is arranged along the opened periphery of the body being in contact with the outer surface of the cleaner and formed of an elastic material, thereby sealing a gap between the outer surface of the cleaner and the body. The storage tank is arranged inside the body and stores a liquid with fragrance or stabilization properties. A pressure difference between the exhaust port and the inside of the storage tank is generated by the velocity of air discharged via the exhaust port by driving the cleaner so that the injecting unit injects the liquid stored in the storage tank via the exhaust port.
