Abstract: A porous bioceramic-modified heating structure includes: a substrate; and a porous bioceramic layer located on a surface of the substrate. The porous bioceramic layer has micro-nano protrusions. A base material of the porous bioceramic layer is calcium phosphate salt. In an embodiment, a thickness of the porous bioceramic layer ranges from 10 ?m to 500 ?m.

Abstract: A vaporizer includes: a vapor generation device having a liquid storage cavity, a vaporization core, and a mounting portion, the liquid storage cavity storing an aerosol-generation substrate, and the vaporization core vaporizing the aerosol-generation substrate to generate vapor; and an air outlet channel insert to be inserted in the mounting portion, the air outlet channel insert including an outer wall, an inner wall, and a first air inlet channel, the inner wall encircling to form an air outlet channel, the outer wall being provided with a first airflow guide channel, and the first airflow guide channel being in communication with the first air inlet channel and the air outlet channel, respectively. When the air outlet channel insert is inserted in the mounting portion, the air outlet channel is in communication with the vaporization core, and the first airflow guide channel is in communication with outside air.

Abstract: An air-curtain forming structure applicable to an electronic vaporization device includes: an airflow channel for delivering vapor; and a first air inlet channel in communication with the airflow channel and for introducing an external airflow into the airflow channel so as to form a blocking airflow between an inner wall of the airflow channel and the vapor.

Abstract: A heating body for heating a vaporized aerosol generation substrate includes: a substrate layer having a first surface and a second surface opposite the first surface; a heating layer formed on the first surface and/or the second surface; and a plurality of through holes having a capillary force. Each through hole of the plurality of through holes is elongated and extends through the first surface to the second surface.
