Abstract: A vaporizer includes: a liquid storage tank for storing liquid; a vaporization core for vaporizing the liquid in the liquid storage tank; and a mounting base provided with an airflow channel penetrating an air inlet end and an air outlet end of the mounting base, a part of the airflow channel close to the air inlet end including a vaporization cavity and a part of the airflow channel close to the air outlet end including an air outlet channel such that vaporized liquid enters the air outlet channel from the vaporization cavity. A condensed liquid collecting structure is provided on the mounting base such that vapor of the vaporization cavity enters the air outlet channel through the condensed liquid collecting structure. The condensed liquid collecting structure collects the liquid condensed and left in the air outlet 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.

Abstract: A vaporization heating control method, applied to an aerosol-generation apparatus having a heater including at least one heating element for heating an aerosol-forming substrate, and a power supply for supplying power to the heating element, the method including: controlling the power supplied to the at least one heating element; controlling the at least one heating element to heat to a preset first temperature range at preset first power in a first stage so as to cause the at least one heating element to start to vaporize the aerosol-forming substrate; and controlling heating power of the at least one heating element to fluctuate in a second stage so as to cause a temperature of the at least one heating element to fluctuate within a preset second temperature range.

Abstract: A vaporizer for vaporizing e-liquid includes: a liquid storage cavity for storing the e-liquid; a mounting base including a housing and a partition plate arranged in the housing, the partition plate having a through hole, and the through hole being in communication with the liquid storage cavity; a vaporization core mounted in the mounting base to heat and vaporize the e-liquid; a seal member arranged between the separating plate and the vaporization core, the seal member including an opening that is in communication with the through hole for the e-liquid to enter the vaporization core through the opening; and at least one vent groove between the mounting base and the seal member, the at least one vent groove being in communication with the liquid storage cavity and external air.

Abstract: A vaporizer includes: a liquid storage tank for storing liquid; a mounting base including a vent channel for transmitting air to the liquid storage tank and a leaked liquid buffer structure having a capillary force, the leaked liquid buffer structure being in communication with the vent channel; and a vaporization core including a porous substrate and a heating element, the porous substrate being in fluid communication with the liquid storage tank and absorbing liquid from the liquid storage tank through a capillary force, the heating element heating and vaporizing the liquid of the porous substrate. The vaporization core is located between the liquid storage tank and the leaked liquid buffer structure. The leaked liquid buffer structure abuts the porous substrate and refluxes liquid leaked from the vent channel to the porous substrate.
