Atomizer, electronic atomization device and atomization assembly for electronic atomization device

Technical Field

The embodiment of the application relates to the technical field of electronic atomization, in particular to an atomizer, an electronic atomization device and an atomization assembly for the electronic atomization device.

Background

Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release the compounds without burning.

An example of such a product is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol provision articles, for example, so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize it, producing an inhalable aerosol. Known electronic atomizing devices draw and store a liquid matrix through a porous ceramic body and generate an aerosol by heating the liquid matrix within the porous ceramic body with a heating element coupled to a surface of the porous ceramic body. The applicant in chinese patent CN209628629U proposes an electronic atomizing device employing a hollow tubular porous ceramic body, wherein liquid is sucked through an outer surface of the tubular porous ceramic body as a liquid suction surface, and a heating element is bonded to a hollow inner surface of the porous ceramic body to heat a liquid matrix, and the liquid matrix and an axially output aerosol are simultaneously transferred radially from a tubular portion of the porous ceramic body.
