Abstract: Provided are an electronic atomization device and an atomization assembly thereof, and a manufacturing method of the atomization assembly. The atomization assembly includes a porous matrix and a heating body. The porous matrix includes an atomization face. The heating body includes a heating part and at least one fixing part connected to the heating part. The at least one fixing part is embedded in the porous matrix, such that the heating body is mounted on the porous ceramic matrix and the heating part is arranged to correspond to the atomization face. The beneficial effect is that mounting of the heating body is realized by having the fixing part embedded in the porous matrix to improve reliability of the atomization assembly.

Abstract: An atomizer, a liquid storage assembly thereof and an electron atomizing device are disclosed. The atomizer includes an atomizing core assembly having a liquid inlet. The liquid storage assembly includes a housing defining a liquid storage cavity and a first assembling hole, wherein the first assembling hole is configured to receive an end of an atomizing core assembly; an inner wall arranged in the liquid storage cavity, configured to sleeve around the atomizing core assembly, wherein a capillary gap is defined between the inner wall and an outer wall of the atomizing core assembly, and the capillary gap is configured to guide liquid in the liquid storage cavity to pass through the liquid inlet.
