Abstract
An electronic vaporization apparatus includes a vaporization core, which includes a porous substrate and a heating element. The porous substrate includes a liquid absorbing surface and a vaporization surface. The heating element is arranged on the vaporization surface. The porous substrate includes a liquid penetration portion close to the vaporization surface, and a temporary liquid storage portion, which is a portion of a volume of the porous substrate occupied by e-liquid with a maximum vaporizable volume Q c1 in an inhalation cycle of the vaporization core. In any inhalation cycle of continuous inhalations, the vaporization core meets: Q cn ≥Q xn ≥Q bn , where Q cn represents a volume of e-liquid stored in the temporary liquid storage portion before an n th inhalation cycle starts, Q xn represents a volume of e-liquid actually vaporized during the n th inhalation cycle, and Q bn represents a volume of e-liquid entering the porous substrate during the n th inhalation cycle.
