Abstract: An atomization core includes: a seat comprising an atomization chamber; a liquid guiding member arranged inside the atomization chamber for guiding an aerosol-generating substrate; a heating component arranged on the liquid guiding member and for atomizing, when energized, the aerosol-generating substrate; and an electrode lead electrically connected to the heating component and fixing the heating component to the liquid guiding member.

Abstract: A vaporizer includes: a bottom plate having a first surface and a second surface arranged oppositely; a vaporization base arranged on and covering the first surface of the bottom plate and cooperating with the first surface of the bottom plate to form a vaporization cavity; a vaporization core accommodated in the vaporization cavity, the vaporization core heating and vaporizing liquid in the vaporization cavity when energized; and a liquid guiding assembly for absorbing liquid on the bottom plate, the liquid guiding assembly including: a first liquid guiding portion arranged on the first surface of the bottom plate and cooperating with the first surface of the bottom plate to form at least one first liquid guiding channel; and a second liquid guiding portion including at least one second liquid guiding channel, one end of the second liquid guiding channel being in communication with the first liquid guiding channel.

Abstract: An electronic vaporization device includes: a suction nozzle portion; an airflow sensor; and a start channel, one end of the start channel being in communication with the suction nozzle portion and an other end of the start channel being in communication with the airflow sensor. A liquid absorbing portion is arranged at a section of the start channel close to the airflow sensor, the liquid absorbing portion absorbing liquid flowing through the start channel through a capillary force.
