AI Technical Summary
Technical Problem
Fresh air ducts are prone to cause indoor dust pollution and noise pollution during use, and existing technologies lack effective filtering and noise reduction functions.
Method used
A fresh air duct system was designed, which includes an air inlet pipe, an air outlet pipe, a dust screen and a noise reduction box. The dust screen is used to filter dust in the air, and the noise is reduced through the design of ventilation holes. The sudden change of cross-sectional area and the discontinuity of acoustic impedance are used to reduce noise propagation.
Benefits of technology
It achieves air filtration and noise reduction, prevents indoor dust and noise pollution, and improves indoor air quality and comfort.

Abstract
The utility model relates to the technical field of fresh air pipelines, in particular to a fresh air pipeline system which comprises an air inlet main pipe, an air outlet main pipe and a noise reduction box, first installation rods which are symmetrically distributed are installed in the air inlet main pipe, a driving device is installed between the first installation rods, and a driving belt wheel is installed on a main shaft of the driving device. Fan blades are installed at the tail end of a main shaft of the driving equipment, dustproof nets are installed at the starting ends of the air inlet main pipe and the air outlet main pipe correspondingly, frames are arranged on the outer sides of the dustproof nets, a second connecting plate is installed between the frames, a second air inlet pipe is installed at the tail end of the air inlet main pipe, and a second air outlet pipe is installed at the tail end of the air outlet main pipe. The noise reduction box is installed on the outer side of the second air inlet pipe and the outer side of the second air outlet pipe, and a first air outlet pipe and a first air inlet pipe which extend out of the noise reduction box are installed in the noise reduction box. The air purifier has the advantages that air can be filtered, the dustproof net is convenient to disassemble and clean, and the air purifier has a good noise reduction function.
