Abstract

The invention relates to a ventilation silencer, which is mainly composed of a frame body (1), a high-frequency silencing sheet (2), a low-frequency silencing sheet (3), an exhaust fan (4), a ventilation shutter (5) and an air filtering net (6); the ventilation silencer is characterized in that: the high-frequency silencing sheet (2), the low-frequency silencing sheet (3) and the exhaust fan (4) are arranged in an inner cavity formed by the frame body (1), the ventilation shutter (5) is arranged at a horizontal opening end (11) of the frame body (1), and the air filtering net (6) is arranged at a vertical opening end (12) of the frame body (1); wherein the frame body (1) mainly comprises a case body and a cover board, the cover board is arranged on the surface of the case body to protect the case body, and the frame body (1) is in a 7 shape, and the inner part of the frame body forms a cavity; one side of the frame body (1) forms an exhaust fan mounting door (13), the exhaust fan (4) is arranged at the position of the exhaust fan mounting door (13), the high-frequency silencing sheet (2) is arranged in the horizontal inner cavity of the cavity, and the low-frequency silencing sheet (3) is arranged in the vertical inner cavity of the cavity, thereby achieving the design purposes.

Description

technical field [0001] The invention relates to a muffler, in particular to a ventilation muffler installed on a wall connected to the indoor and outdoor. Background technique [0002] With the progress of society and the rapid development of economy, there are many industrial plants, and the noise in industrial plants seriously affects people's work, study and life. In order to reduce noise and reduce noise pollution, most of them use mufflers to reduce noise. Most of the current mufflers They are all cylindrical or column-shaped, have a simple noise reduction structure, are not highly targeted to low-frequency noise and high-frequency noise, and have poor noise reduction effects, which cannot meet people's needs. Contents of the invention [0003] The purpose of the present invention is to develop a ventilation muffler that solves the above problems, has a simple structure, a small volume, and a wide band of sound-absorbing frequencies. [0004] The present invention ma...
