Technical Problem
[0003]现有的前置过滤器在过滤时，水流先从进水流道流向过滤筒的外侧，再从过滤筒的外侧向内侧流动进行过滤，最后从过滤网的内侧流向出水流道，大颗粒杂质都分散地被残留在过滤筒的外侧，不易收集，并且不易被冲洗干净，从而为杂质的排出增加了难度
Benefits of technology
[0030]本实用新型提供一种前置过滤器，在过滤时，水流流经过滤筒的内部，经过过滤筒过滤后再从过滤筒的外部流出，水流的流动方向为从过滤筒的内侧流向过滤筒的外侧，过滤后的杂质被阻隔在过滤筒的内部，这样设置有利于将过滤后的杂质集中收集在过滤筒的内部，待排污时能够将杂质从过滤筒的底部快速排出，排污更加方便。
