Description

吸尘器消音装置
技术领域
本发明涉及一种吸尘器消音装置。
背景技术
传统的吸尘器的出风消音是通过增加风道曲折性，也就是迷宫式的风道，使得声波在传播过程中的能量损失以及通过风道转弯处安置多孔吸声材料来吸收声能，从而达到降噪的目的，这种结构的主要缺点是消音降噪效果比较差。
发明内容
本发明的目的是：提供一种吸尘器用消音装置，该装置将多种消音结构集中于一体，安装在吸尘器的排风口上，可以大大降低吸尘器在使用时发出的噪音。
本发明的技术方案是：一种吸尘器用消音装置，该装置包括有一个以上安装在出风通道上的、密闭的扩张室，扩张室的两端分别设有与出风通道连接的进风口和出风口，扩张室于垂直气流方向的截面分别大于进风口和出风口的截面积。
本发明进一步的技术方案是：一种吸尘器用消音装置，该装置包括有一个以上安装在出风通道上的、密闭的扩张室，扩张室的两端设有分别与出风通道连接的进风口和出风口，扩张室于垂直气流方向的截面分别大于进风口和出风口的截面积；所述扩张室内设有分隔进风口和出风口的消音隔板，消音隔板上布有小孔；所述扩张室由两半对接组成，消音隔板固定在对接位置上。
本发明更详细的技术方案是：一种吸尘器用消音装置，该装置包括有一个以上安装在出风通道上的、密闭的扩张室，扩张室的两端设有分别与出风通道连接的进风口和出风口，扩张室于垂直气流方向的截面分别大于进风口和出风口的截面积；所述扩张室内设有分隔进风口和出风口的消音隔板，消音隔板上布有小孔；所述扩张室由两半对接组成，消音隔板固定在对接位置上；所述扩张室的两内端面至消音隔板的距离分别大于10毫米而小于100毫米；所述扩张室的垂直气流方向的截面积大于出风口截面积的两倍；所述扩张室的内壁设有吸音材料，吸音材料厚度大于2毫米；所述进风口和出风口的周边钻有小孔；所述进风口和出风口的截面积分别小于5000平方毫米。
本发明的优点是：
1.本发明集多种消音结构于一体，通过多种消音结构来降低吸尘器使用时产生的噪声，大大提高了消音降噪的效果。
2.本发明还可以用多个装置串联起来使用，串联后的消音装置的消音降噪效果会更好。
3.本发明的扩张室可以单独连接在吸尘器的出风通道上，也可以在扩张室内安装消音隔板，安装有消音隔板的扩张室降噪效果会更好。
附图说明
下面结合实施例对本发明作进一步的描述：
为本发明的剖面结构示意图；
其中：1扩张室；2进风口；3出风口；4消音隔板；5小孔；6吸音材料；7小孔。
具体实施方式
实施例：如图1所示，一种吸尘器用消音装置，该装置包括有一个以上安装在出风通道上的、密闭的扩张室(1)，扩张室(1)的两端设有分别与出风通道连接的进风口(2)和出风口(3)，扩张室(1)于垂直气流方向的截面分别大于进风口(2)和出风口(3)的截面积，扩张室(1)内设有分隔进风口(2)和出风口(3)的消音隔板(4)，消音隔板(4)上布有小孔(5)，扩张室(1)可以由两半对接组成，消音隔板(4)固定在对接位置上，扩张室(1)的两内端面至消音隔板(4)的距离分别大于10毫米而小于100毫米，扩张室(1)的垂直气流方向的截面积大于出风口(2)截面积的两倍，扩张室(1)的内壁设有吸音材料(6)，吸音材料厚度大于2毫米，进风口(2)和出风口(3)的周边钻有小孔(7)，进风口(2)和出风口(3)的截面积分别小于5000平方毫米。
使用时，吸尘器的电机排出来的风首先经过进风口(2)进入扩张室(1)的前部，由于截面积的瞬间扩大，从而达到了降低噪音的效果，同时扩张室(1)的四壁的吸音材料(6)又吸收了一部分声能，起到一定的消音效果，然后风和声波通过中间密布小孔(5)的消音隔板(4)，使得声能进一步损失，达到消音效果，接着又进入扩张室(1)的后部，进一步降低噪音，如果在空间允许的条件下，可以再串联几个扩张室(1)，这样的消音降噪效果会更好，本发明的扩张室(1)可以单独连接在吸尘器的出风通道上，也可以在扩张室(1)内安装消音隔板(4)，安装有消音隔板(4)的扩张室(1)降噪效果会更好。
