Abstract (en)
The present disclosure discloses a preparation method of multi-sectional aerosol generating products, wherein, the method includes the following steps: step 1, preparation of filter-tip rod; step 2, filling of an aerosol generating material; step 3, forming of an aerosol generating rod (6). The method of compounding before filling of the present disclosure can greatly improve production efficiency, to ensure that the plugging part (2) and the filtering part (4) are stable without moving during smoking or transportation, and better maintain consistency of axial lengths of the cavity section of different samples. Besides, in the present disclosure, the flowing aerosol generating material is filled by squeezing, which is dried and expands, so that the flowing aerosol generating material is solidified to form a fixed aerosol generating rod (6), production efficiency is higher by the method of squeezing, the aerosol generating rod (6) obtained after drying and expansion has pore structure, which can facilitate release and circulation of aerosols.
