    摘要： The present application provides an electronic atomization device and a control circuit therefor. The control circuit (1) includes an airflow sensor (11), a power supply capacitor (12) and a control chip (13). The control chip (13) includes a logic controller (M1), a unidirectional conduction tube (D1) and a switch tube (K1), a power supply pin (VDD), an atomization pin (AT) and a ground pin (GND); the logic controller (M1) is connected to a first end (a1) of the airflow sensor (11) and a first end (b1) of the switch tube (K1); and through the power supply pin (VDD), is connected to a first end (c1) of the power supply capacitor (12) and a second end (b2) of the switch tube (K1); and through the ground pin (GND), is connected to a positive electrode of the unidirectional conduction tube (D1), a second end (a2) of the airflow sensor (11) and a second end (c2) of the power supply capacitor (12); a negative electrode of the unidirectional conduction tube (D1), through the atomization pin (AT), is connected to a third end (b3) of the switch tube (K1); the power supply pin and the atomization pin are configured to connect with the peripheral power supply module and atomization module to achieve an electronic atomization function.
