A split-flow ventilation duct

Abstract

This utility model relates to the field of ventilation duct technology, specifically to a diversion ventilation duct, including a main duct, a first branch pipe, a second branch pipe, and a diversion assembly. The first branch pipe is located on one side of the main duct, and the second branch pipe is located on the side of the main duct opposite to the first branch pipe. The diversion assembly includes a rotating component, a baffle plate, an extension plate, a linkage seat, and a control component. The baffle plate is connected to the main duct through the rotating component, which is installed inside the main duct and supports the baffle plate. The extension plate is slidably connected to the baffle plate and is located on one side of the baffle plate. The linkage seat is rotatably connected to the extension plate and is located on the side of the extension plate away from the baffle plate. The control component controls the movement of the linkage seat. This invention solves the problem that although existing technologies can achieve diversion of ventilation ducts, they do not have the ability to guide and direct airflow. The airflow becomes turbulent within the ventilation duct, and the turbulent airflow impacts the inner wall of the duct, generating significant noise and affecting the comfort of the working environment.
