An atomizerincludes a plurality of liquid storage cavitiesand a heating assembly. Media to be atomized are stored in the liquid storage cavities. Different media to be atomized are stored in at least some of the plurality of liquid storage cavities. That is, the media to be atomized stored in all the liquid storage cavitiesmay be different, or the media to be atomized stored in some liquid storage cavitiesare different, and the media to be atomized stored in other liquid storage cavitiesare identical. The heating assemblyincludes a substrate. The substratehas a liquid absorbing surfaceand an atomization surfacethat are oppositely arranged. The substratefurther has a plurality of liquid guide holes. The liquid guide holesare used for guiding the medium to be atomized from the liquid absorbing surfaceto the atomization surface. The atomization surfaceincludes a plurality of atomization regionsThe plurality of atomization regionsand the plurality of liquid storage cavitiesare arranged in a one-to-one correspondence manner. That is, one atomization regionis arranged corresponding to one liquid storage cavity. One atomization regiononly atomizes a medium to be atomized in one liquid storage cavity. The heating assemblyfurther includes a heating element. The heating elementis arranged on the atomization surface, or at least a part of the substratehas an electrically-conductive heating capability, to serve as the heating element. The heating elementis used for heating the plurality of atomization regionsto different atomization temperatures. In the present application, the atomization temperature in a same atomization regionis not equal everywhere. Thus the atomization temperature in the same atomization regionrefers to an average temperature in the same atomization regionThe heating elementheats the plurality of atomization regionsto different atomization temperatures. Specifically, after heated by the heating element, the plurality of atomization regionshave different average temperatures. The heating assemblyis electrically connected to the main unit, such that the main unitprovides electric energy for the heating assemblyand controls the heating assemblyto atomize the medium to be atomized.

Specifically, the plurality of liquid storage cavitiesare arranged in the atomizer, the atomization surfaceincludes the plurality of atomization regionsand the plurality of atomization regionsand the plurality of liquid storage cavitiesare arranged in a one-to-one correspondence manner. Since different media to be atomized are stored in the plurality of liquid storage cavities, one liquid storage cavityprovides one medium to be atomized for one atomization regionand the atomization regionatomizes only this medium to be atomized. The atomization temperatures of different atomization regionsare different, such that the atomization temperature of each atomization regionis designed according to a characteristic of a medium to be atomized corresponding to the atomization region, and it is guaranteed that all the media to be atomized in the plurality of liquid storage cavitiescan be sufficiently atomized and volatilized; or a same medium to be atomized is stored in some liquid storage cavities, but the atomization temperatures of the atomization regionscorresponding to the same medium to be atomized are different, such that the same medium to be atomized from different liquid storage cavitiesmay be atomized at different temperatures to generate aerosols with different flavors.

It should be noted that in the existing technology, flavored liquid atomized by an electronic atomization device is a mixture. Components of the mixture are distributed according to a requirement into the plurality of above media to be atomized, are respectively stored in the plurality of liquid storage cavities, and are respectively atomized by using different atomization temperatures. Thus sufficient atomization and volatilization of each medium to be atomized is guaranteed, and a poor taste caused by indiscriminate atomization of various components of the flavored liquid by using a same heating assembly is avoided.

In an embodiment, the plurality of liquid storage cavitiesand the heating assemblyform an integrated structure, and are specifically manufactured by using a chip machining technology or a semiconductor machining technology.

In an embodiment, the liquid guide holesin different atomization regionshave different diameters, and/or the liquid guide holesin different atomization regionshave different lengths, and/or the liquid guide holesin different atomization regionshave different porosities, to cause the different atomization regionshave different liquid supply speeds. In combination with the different atomization temperatures of the different atomization regionsit is guaranteed that the plurality of media to be atomized in the plurality of liquid storage cavitiesare sufficiently atomized.

In an embodiment, the diameter of each liquid guide holeranges from 2 μm to 100 μm; and/or the porosity of each liquid guide holeranges from 10% to 70%. It may be understood that the diameter and/or the porosity of the liquid guide holeis specifically designed according to a liquid supply requirement of different atomization regions

The second sub-substrate-has a second atomization region-. The first atomization region-is arranged corresponding to the first liquid storage cavity-, and is used for atomizing the first medium to be atomized. The second atomization region-is arranged corresponding to the second liquid storage cavity-, and is used for atomizing the second medium to be atomized. The heating assemblyincludes a heating elementarranged on the atomization surface. The heating elementis used for heating the first atomization region-to a first atomization temperature and heating the second atomization region-to a second atomization temperature. Since the boiling point of the first medium to be atomized in the first atomization region-is lower than the boiling point of the second medium to be atomized in the second atomization region-, the first atomization temperature in the first atomization region-is lower than the second atomization temperature in the second atomization region-. It should be noted that the heating elementand the liquid storage cavitiesare located at two sides of the substrate. The first liquid storage cavity-and the second liquid storage cavity-represent same structural meanings as the liquid storage cavity, and the first liquid storage cavity-and the second liquid storage cavity-are introduced merely for ease of description.
