The air then passes through the central gas flow path 21 of the airflow passage segment 2, through the filter segment 1, and into the smoker's mouth. 【0032】 Furthermore, a filter material can be selectively added to the central gas flow path 21 of the airflow passage segment 2 to form a filter member, which can filter aerosols. The material of the filter member may be acetic acid fiber, polylactic acid fiber, plant polysaccharide, or plant porous material. The aerosol generated in the aerosol generating material segment 3 first passes through the filter material provided in the central gas flow path 21 to complete initial filtering.

The bottom wall of the coating layer 4 is provided with an intake hole that allows ventilation to the outside, and air is drawn in simultaneously from the bottom wall and the side wall, which increases the amount of atomization and contributes to lowering the intake resistance and the temperature at which air enters the mouth. The position of the coating layer 4 corresponds to the airflow passage segment 2.
