Patent attributes
An electronic apparatus includes a casing, a vent structure on the casing, and an electronic device inside the casing. The vent structure is used for a unidirectional flow and includes a frame and a louver. The louver includes a sheet body and a shaft. The sheet body includes a bent portion, a first and a second portion which oppositely extend from the bent portion and bind together. The shaft passes through a through hole formed by the bent portion and is connected to the frame, so that the sheet body is rotatable. When the louver is located at a closed position, the sheet body covers at least a portion of an opening structure of the frame. The louver is structurally simple and can be made of light material, which is conducive to improving the rotation agility of the louver and reducing the noise probably produced when in operation.
