ELECTRONIC ATOMIZATION DEVICE AND POWER SUPPLY ASSEMBLY THEREOF

The present invention relates to an electronic atomization device and a power supply assembly thereof. The power supply assembly is provided with a first mounting hole (12) configured to mount a magnetic member (20), where an inner wall of the first mounting hole (12) is provided with a vent groove (121); and the power supply assembly includes an airflow sensor, and the airflow sensor is in air communication with the vent groove. The inner wall of the first mounting hole configured to mount the magnetic member is configured to provide the vent groove, so that the airflow sensor is in air communication with an atomization assembly. In this way, a start airway does not need to be additionally provided for the airflow sensor on the power supply assembly, which saves space on the power supply assembly and is conducive to the miniaturization and flat design of a product.
