AI Technical Summary
Technical Problem
The existing smoke exhaust fan cannot control the amount of air intake, which leads to an increase in impeller load and thus an increase in fan energy consumption.
Method used
By installing an adjustable baffle system on the air inlet plate, the rotation of the support ring and the adjusting plate is driven by an electric push rod, which changes the baffle gap to adjust the air intake and avoids the impeller operating under high load.
Benefits of technology
Effectively control the air intake, reduce the load on the impeller, lower the energy consumption of the fan, and improve energy efficiency.

Abstract
The utility model relates to the technical field of smoke exhaust air cabinets, in particular to an environment-friendly smoke exhaust air cabinet which comprises a protection box. An air inlet plate and a smoke exhaust assembly are further included. An air inlet plate is arranged in the protection box, a plurality of rotating rods are rotationally arranged on the inner wall of the air inlet plate, baffles are fixedly connected to the outer walls of the rotating rods, one end of each rotating rod penetrates through the air inlet plate and is fixedly connected with a first adjusting plate, a second adjusting plate is rotationally arranged at the lower end of the first adjusting plate, and a smoke exhaust assembly is arranged in the protection box. The electric push rod is started to drive the supporting ring to be close to the shell, at the moment, the second adjusting plate can push the first adjusting plate to rotate, the rotating rod and the first adjusting plate are fixedly connected, the rotating rod can rotate along with the first adjusting plate, and therefore the baffles are driven to rotate, gaps between the baffles are changed, and the air inlet amount is changed. High-load operation of the wind wheel is avoided, and the problem that due to the fact that the air inlet amount cannot be controlled, large load is generated on the impeller, and energy consumption of the fan is increased is solved.
