Technical Problem
[0005]但是现有的换气装置在工作时会将外部的灰尘与有害物质吹进地下空间内，虽然设有过滤组件，但是在过滤组件使用后需要工人对其进行清洗，而现有的过滤组件均为通过紧固件固定在换气装置上，工人需要频繁装卸紧固件才能将过滤组件取下，使得清洁效率降低
Benefits of technology
[0022](1)本方案通过将过滤组件固定在顶板的下端，顶板嵌合固定在安装组件内，即可将过滤组件安装固定在箱体外壳内，整个过滤组件的安装或拆卸方便，提高了换气装置的安装效率；另一方面，灰尘滤板需要更换时，断开过滤组件对将灰尘滤板的吸附，将灰尘滤板取下，更换新的灰尘滤板，磁吸附固定在过滤组件下方，完成更换，避免了通过紧固件繁琐拆卸进行更换的费时费力，更换方便快捷，提高了换气装置的清洁效率。
