Abstract

The invention relates to ventilation devices, in particular to a ventilation device capable of lowering noise. The ventilation device capable of lowering noise aims at solving the problem that when an existing ventilation device is used for ventilating a room, noise pollution is brought into the room due to the fact that outdoor noise is introduced into the room. The ventilation device comprises an outer support plate, a first micro-perforation plate, a second micro-perforation plate and an inner support plate. The outer support plate is a circular arc plate. The outer support plate and the inner support plate are vertically arranged. The first micro-perforation plate and the second micro-perforation plate are vertically arranged between the outer support plate and the inner support plate. A first cavity is formed by the outer support plate and the first micro-perforation plate. A second cavity is formed by the inner support plate and the second micro-perforation plate. A ventilation passage is formed by the first micro-perforation plate and the second micro-perforation plate. The ventilation device capable of lowering noise is applied to the building field.

Description

technical field

[0001] The invention relates to a ventilation device, in particular to a ventilation device capable of reducing noise, and belongs to the construction field. Background technique

[0002] In architecture, a window is an opening made in a wall or roof to allow light or air to enter a room. When the windows are closed at night, the ventilator will introduce natural ventilation into the room, but the ventilator also introduces the outdoor noise into the room while introducing the outdoor natural wind, which brings noise pollution to the room. Contents of the invention

[0003] In order to solve the problem that the existing ventilator introduces outdoor noise into the room while ventilating the room, and brings noise pollution to the room, the invention further proposes a ventilation device capable of reducing noise.

[0004] The technical scheme adopted by the present invention to solve the above-mentioned problems is: the present invention comprises an oute...
