Heating element, atomizer, and aerosol-generating device

Abstract

The application discloses a heating body, an atomizer and an aerosol generating device. The heating body comprises a storage member, a base and a heating member. The storage member is provided with a storage cavity for storing aerosol generating substrate. The base comprises a porous layer and a dense layer. The porous layer is provided with a flow channel for the flow of aerosol generating substrate. The dense layer and the storage member are respectively arranged on opposite sides of the porous layer. The periphery of the base extends beyond the periphery of the storage member. The dense layer is used to prevent the aerosol generating substrate from flowing out from the side of the porous layer connected to the dense layer. The heating member is arranged on the base and is used to heat the aerosol generating substrate. In the heating body, the atomizer and the aerosol generating device of the application, the heating member can preheat the aerosol generating substrate through the storage member, without the need for additional preheating circuit, thereby simplifying the structure of the heating body and facilitating the miniaturization of the heating body.
