Disposable electronic atomizer

The utility model relates to a disposable electronic atomizer, belongs to the field of electronic atomizers, and aims to solve the problems that according to a conventional disposable electronic atomizer, after an air inlet channel is closed, a power source of the disposable electronic atomizer is still in a discharging state, an airflow sensor still works, and mistaken starting is prone to occurring during transportation or static carrying. The disposable electronic atomizer comprises an atomizer body, a control main board, an assembly block, a function block and an airflow sensor, the airflow sensor is arranged on an installation part, the airflow speed of an airflow opening is detected through the airflow sensor, and the situation that the disposable electronic atomizer is not started by mistake when the disposable electronic atomizer is idle is avoided; the problems that false starting is prone to occurring during transportation or static carrying, and safety and power saving are not enough are solved. 本申
