Abstract (en)
[origin: EP3981271A1] Disclosed are an electronic cigarette and its airflow switch bracket, airflow switch assembly and power supply device. The airflow switch bracket includes a base, a bottom surface of the base being provided with a groove for accommodating an airflow switch, the groove extending from the bottom surface of the base toward a top surface of the base so that a thin-walled layer sealed on the groove is formed on the top surface of the base. The thin-walled layer is deformable when an air flow passes by, so that a negative pressure is generated in a space between the groove and the airflow switch to control the on/off of the airflow switch. The airflow switch bracket of the invention adopts a thin-walled layer to replace the arrangement of through holes, and thus the airflow switch bracket is configured as a closed bracket. In the electronic cigarette, the thin-walled layer can be deformed when the airflow passes by, thereby controlling the on/off of the airflow switch. It can effectively prevent tobacco juice from leaking to the airflow switch or contaminating the adapter board or a battery, thereby effectively increasing the service life and safety performance of the electronic cigarette.
