Description
Technical field
It the utility model is related to a kind of ventilation sound arrester.
Background technology
With the development of society, the noise pollution of modern society is increasingly serious, show that noise is dirty according to modern medical service research
Dye greatly threatens the physical and mental health of people.
Utility model content
The purpose of this utility model is to overcome the weak point in prior art, there is provided one kind ventilation sound arrester.
In order to achieve the above object, the present invention uses following scheme：
One kind ventilation sound arrester, includes at least two layers of ventilation noise insulation block, be provided with the ventilation noise insulation block to
A few oblique air vent through ventilation noise insulation block, the oblique air vent that the adjacent two layers are divulged information in noise insulation block are connected and formed curved
The silencers channel of folding, the silencers channel can not only noise reduction can also maintain the circulation of air.
In one or more embodiments, tiltedly air inlet and venthole are provided with air vent described, the air inlet with
Gas outlet is formed as ellipse, the gas outlet of the ventilation noise insulation block on the upper strata and the air inlet phase of the ventilation noise insulation block of lower floor
Even.
In one or more embodiments, the ventilation noise insulation block is made as soundproof wall using light-proof material.
In one or more embodiments, the ventilation noise insulation block is made and applied on door and window using transparent material.
In one or more embodiments, described silencers channel extends passage for the bending of rule.
In one or more embodiments, it is laminated by structure identical ventilation noise insulation block positive and negative and formed.
Beneficial effect：The utility model provides ventilation sound arrester, and it uses the superposition of multilayer ventilating noise reduction block and tiltedly ventilation
Hole is connected to form bending silencers channel, can effectively reduce noise, keeps the circulation of room air.
