Abstract (en)

An atomizing structure (100), an atomizer, and an aerosol generating device are provided. The atomizing structure (100) includes a heating element (120) and an atomizing core assembly (110) including an atomizing portion (111) and a guiding portion (112). The heating element (120) is at least partially embedded in the atomizing portion (111), the atomizing portion (111) is fixed in the guiding portion (112), the atomizing portion (111) has an outer wall (116), the guiding portion (112) has an inner wall portion (112A), and the outer wall (116) is in partial contacted with the inner wall portion (112A), the guiding portion (112) is in contact with an atomizing medium, and is configured to transport the atomizing medium to the atomizing portion (111) through the inner wall portion (112A) and the outer wall (116) in sequence, the outer wall (116) forms a first atomizing surface, and a first air channel (191) for transporting the aerosol generated by the first atomizing surface is provided between the outer wall (116) and the inner wall portion (112A).
