The utility model discloses a cooling filter tip, and relates to the field of tobacco filter tips. The device comprises a body, a suction nozzle is arranged on the body, and the body is of a cylinderstructure made of metal materials. A first channel, a second channel, a mixing cavity and an air inlet cavity are formed in the body. The mixing cavity is located above the body, and the air inlet cavity is located below the body. The first channel is of a spiral structure, one end of the first channel communicates with the air inlet cavity, and the other end of the first channel communicates withthe mixing cavity. One end of the second channel communicates with the air inlet cavity, and the other end of the second channel communicates with the mixing cavity. A connecting sleeve is fixedly arranged below the body and is of an annular structure, and a center hole of the connecting sleeve is communicated with the air inlet cavity. When the suction nozzle sucks smoke, the smoke reaches the mixing cavity through the first channel and the second channel. As the first channel is of a spiral structure, heat dissipation is fast, the overall temperature of the two kinds of smoke mixed in the mixing cavity is rapidly reduced, and the cooling purpose is achieved. The structure is ingenious, the size is small and the weight is light.
