Abstract: A control assembly, including: a control circuit, a battery module, and a first interface and a second interface configured to connect the control assembly with an external atomization module. The battery module is provided with a first lead penetrating therethrough. The first interface and a first pin of the control circuit are connected to two electrode terminals of the battery module, respectively. The second interface and a second pin of the control circuit are connected to two terminals of the first lead, respectively. The first pin is an atomization pin, and the second pin is a power pin; or alternatively, the first pin is the power pin, and the second pin is the atomization pin; or alternatively, the first pin is a ground pin, and the second pin is the atomization pin; or alternatively, the first pin is the atomization pin, and the second pin is the ground pin.

Abstract: An electronic atomization device and a control circuit therefor are provided. The control circuit includes an airflow sensor, a power supply capacitor and a control chip including a logic controller, a unidirectional conduction tube and a switch tube, a power supply pin, an atomization pin and a ground pin; the logic controller is connected to a first end of the airflow sensor and a first end of the switch tube; and through the power supply pin, is connected to a first end of the power supply capacitor and a second end of the switch tube; and through the ground pin, is connected to a positive electrode of the unidirectional conduction tube, a second end of the airflow sensor and a second end of the power supply capacitor; a negative electrode of the unidirectional conduction tube, through the atomization pin, is connected to a third end of the switch tube.
