Binary assembly type aerosol generating product and preparation method thereof

The invention discloses a binary assembly type aerosol generating product. The aerosol generating product comprises an aerosol generating unit (1) and a filter stick unit (2), the aerosol generating unit (1) is of a cylindrical structure with a cavity (11), and one end of the aerosol generating unit (1) is an open end; the filter stick unit (2) is of a tubular structure and comprises a cooling section pipe body (22); and at least part of the cooling section pipe body (22) is axially inserted into the cavity (11) of the aerosol generating unit (1) from the open end of the aerosol generating unit (1). The binary assembly type aerosol generating product can be obtained by simply assembling two elements, so that the processing procedures are reduced, and the product cost is reduced. The sealing piece (3) of the aerosol generating product can be completely airtight, the interior of the aerosol generating unit is in an oxygen-deficient state, under the condition, combustion cannot be generated when the heating temp
