US Patent 11589428 Electronic cigarette, atomizer and heating assembly thereof

A heating assembly is used for an atomizer of an electronic cigarette. The heating assembly includes an adsorption member, and at least one heating element for generating heat after being electrified. The adsorption member comprises at least one surface defining at least one fixing groove therein, and the at least one heating element is disposed in the at least one fixing groove. The heating element is disposed in the fixing groove, so that an aerosol-generating substrate on the adsorption member can be more sufficiently coated on the heating element and dispersed to an outer surface of the heating element.
