Background technique

An electronic atomization device generally includes an atomizer, a power supply, and a control circuit. The atomizer includes a liquid storage chamber, an airflow channel, and an atomizing core. The airflow channel includes an air inlet channel, an atomization chamber, and an air outlet channel. The liquid in the liquid storage chamber flows to the atomizing core. When the user inhales, the control circuit controls the power supply to provide electric energy to heat the atomizing core and atomize it to generate aerosol in the atomizing chamber.
