Abstract

The invention provides an electronic atomization device and a control circuit and method thereof, and relates to the technical field of electronic atomization. The control circuit comprises an airflowsensor, a power supply capacitor and a control chip, wherein the control chip comprises a logic controller, a one-way conduction tube, a switch tube, a power supply pin, an atomization pin and a grounding pin. The logic controller is respectively connected to the first end of the airflow sensor and the first end of the switch tube, and is connected to the first end of the power supply capacitor and the negative electrode of the one-way conduction tube through the power supply pin. And the positive electrode of the one-way conduction tube is connected to the second end of the switch tube through the atomization pin. The logic controller is connected to the third end of the switch tube, the second end of the airflow sensor and the second end of the power supply capacitor through the grounding pin. The atomization pin and the grounding pin of the control chip are used for being connected with a power module and an atomization module so as to achieve the electronic atomization function. By reducing the number of welding leads, the production cost is reduced, and the product reliability is improved.

Description

technical field [0001] The present application belongs to the technical field of electronic atomization, and in particular relates to an electronic atomization device, a control circuit and a control method thereof. Background technique [0002] As people's awareness of health and environmental protection gradually increases, more and more users begin to choose to use electronic atomization devices (such as using electronic cigarettes as a substitute for cigarettes), and the market for electronic atomization devices is also growing. In order to gain an advantage in the fierce market competition, the product quality and production cost of electronic atomization devices are issues that manufacturers need to consider. [0003] At present, in the production and manufacturing process of electronic atomization devices, chip design manufacturers usually assemble control chips, PCB boards and peripheral components into modules for sale, and actual electronic product manufacturers ne...
