Description

一种隔音罩
技术领域
本实用新型涉及隔音罩领域，具体是一种隔离机械设备产生的噪音的隔音罩。
背景技术
噪音，是一种普遍存在的污染源，高分贝的噪音损坏听力，影响人体健康。尤其在一些工厂的厂房中，各种机械设备在运转时总会发出相应的噪音，尤其是大型的设备在运转时，其噪音的分贝尤其高，对操作设备的工人的人体健康造成损害。
实用新型内容
本实用新型要解决的技术方案为提供一种隔音罩，解决现有工厂中大型设备运转产生的噪音大影响工人人体健康的问题。
本实用新型的技术方案为：
一种隔音罩，包括套装于机械设备外的微孔层、套装于微孔层外的隔音外壳和设置于微孔层和隔音外壳之间的吸音海绵层。
所述的隔音罩上设置有进出口。
本实用新型结构简单，安装方便，包括的三层结构具有很好的隔音效果，满足厂房中对噪声环境的要求，且制造成本低。
附图说明
图1是本实用新型层状结构的局部剖视结构示意图。
图2是本实用新型的结构示意图。
图3是微孔板的结构示意图。
具体实施方式
见图1、图2，一种设置有进出口4的隔音罩，包括套装于机械设备5外的微孔层1（见图3）、套装于微孔层1外的隔音外壳2和设置于微孔层1和隔音外壳2之间的吸音海绵层3。
机械设备生产中产生的噪音经微孔层1射入吸音海绵层3，当声波入射到吸音海绵层3中时，可引起吸音海绵层3空隙中的空气振动，由于空气的粘滞阻力，空气与孔壁的摩擦，使一部分声能转化成热能而被消耗，同时隔音外壳2可将部分声能进行阻隔，保证了很好的隔音效果。

Claims (2)

1.一种隔音罩，其特征在于：包括套装于机械设备外的微孔层、套装于微孔层外的隔音外壳和设置于微孔层和隔音外壳之间的吸音海绵层。
2.根据权利要求1所述的一种隔音罩，其特征在于：所述的隔音罩上设置有进出口。
