Description

Electron smog spinning disk atomiser and electron cigarette
Technical Field
The embodiment of the application relates to electron cigarette technical field, especially relates to an electron smog spinning disk atomiser and electron cigarette.
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 compounds without burning.
An example of such a product is a heating device that releases a compound by heating rather than burning the material. For example, the material may be tobacco or other non-tobacco products, which may or may not include nicotine. As another example, there are aerosol-providing articles, e.g., so-called e-vapor devices. These devices typically contain a liquid that is heated to vaporize it, thereby generating an inhalable vapor or aerosol. The liquid may comprise nicotine and/or a fragrance and/or an aerosol generating substance. As a known electronic cigarette, the' 201810150690.7 patent employs a block-shaped porous ceramic body having grooves on an upper surface thereof as a medium for liquid substrate transfer, and provides a heating element on a lower surface opposite the grooves for heating liquid substrate absorbed by the porous ceramic body, thereby generating an aerosol for inhalation. The known electronic cigarette device matched with the assembly of the porous ceramic body needs to adopt the rigid supporting element to accommodate and maintain the porous ceramic body and then coat the silica gel sealing element to be integrally assembled in the electronic cigarette tool, so that more parts are relatively inconvenient to assemble.
