Electronic atomization device and method thereof

The invention provides an electronic atomization device and a method thereof. The electronic atomization device comprises an air inlet, an air outlet and an airflow channel extending from the air inlet to the air outlet. The atomizing assembly is used for atomizing the liquid substrate to generate aerosol; air flows into the airflow channel through the air inlet, flows through the atomization assembly and then flows out of the air outlet. The sensor is used for sensing the air pressure in the airflow channel so as to output a characteristic value; and controlling the electronic atomization device to be in an unlocking state according to the characteristic value output by the sensor or a comparison result of a parameter value corresponding to the characteristic value and a preset threshold value. The electronic atomization device is controlled to be unlocked by comparing the characteristic value output by the sensor or the parameter value corresponding to the characteristic value with the preset threshold valu
