Abstract
This application provides an e-cigarette vaporizer and an e-cigarette. The e-cigarette vaporizer includes an outer housing including an open end and an end cap arranged at the open end, where a liquid storage cavity and a sealing base configured to seal the liquid storage cavity are provided in the outer housing; a sealing ring is arranged between the end cap and the outer housing; a vaporization cavity is provided between the sealing ring and the sealing base, and the liquid substrate is vaporized in the vaporization cavity to generate aerosol released to the vaporization cavity; and a plurality of liquid storage grooves configured to adsorb and hold aerosol condensate are provided in the vaporization cavity. The e-cigarette vaporizer uses the liquid storage groove for absorbing the condensate through the capillary action, and prevents the condensate from being taken out along with inhaling airflow during inhaling.
