2015 
The invention relates to a composite filter tip for a heating type non-combustion cigarette. The composite filter tip comprises a solid filter (1), a first hollow filter or first cavity (2), a second hollow filter (3) and a third hollow filter or third cavity (4) which are connected in sequence, wherein a fourth cavity (7) is formed in the hollow portion of the first hollow filter or first cavity (2), a sixth cavity (5) is formed in the hollow portion of the third hollow filter or third cavity (4), the fourth cavity (7) and the sixth cavity (5) are in airflow communication through a fifth cavity (6) located in the hollow portion of the second hollow filter (3), and the diameter of the fifth cavity (6) is smaller than that of the fourth cavity (7) and that of the sixth cavity (5). The composite filter tip has a smoke mixing function, a smoke response time shortening function and other functions and has the advantages of being capable of increasing the smoke amount of the heating type non-combustion cigarette, reducing smoke temperature, improving the smoking sensory quality of the heating type non-combustion cigarette and the like.
