Technical Problem
[0003]在长时间使用后，污垢会积累附着在过滤筒的表面难以冲洗干净，长期累积的杂质逐渐阻塞过滤筒，会使得后端的出水量减少，引起水压的压降，还会影响前置过滤器的使用寿命
Benefits of technology
[0026]本实用新型提供一种前置过滤器的阀芯结构及前置过滤器，在过滤状态下，将排污口关闭，使得分流器上移至过滤位置，此时分流器的内腔不通水，进水流道通过分流壳体的内腔与过滤筒的内腔连通，水流流经分流壳体的内腔后进入过滤筒内部进行过滤。在排污状态下，将排污口打开，使得分流器下降至排污位置，此时分流壳体的内腔不通水，进水流道通过分流器的内腔与过滤筒的内腔连通，水流流经分流器的内腔，产生的涡流冲击刮洗组件，从而驱动刮洗组件旋转并刮洗掉过滤筒的内壁上附着的杂质，使堆积附着的杂质从过滤筒的内壁上脱落，并随着水流从排污口排出。因此，该前置过滤器通过设置上述的阀芯结构，能够便于实现前置过滤器的过滤功能和排污功能的切换，并且在排污状态下，通过水流的动能直接驱动刮洗组件旋转，从而实现过滤筒的自动清理，使过滤筒的过滤效果能够持续地发挥作用，整个清洗过程只需人工打开排污口即可，操作方便快捷，使得过滤筒的清洗难度大幅度降低。

Abstract
The utility model belongs to water purification equipment technical field discloses a valve core structure and prefilter of prefilter. The valve core structure of prefilter includes filter drum, scrape and wash subassembly and shunt subassembly, scrape and wash subassembly rotatablely set up in the filter drum, shunt subassembly includes shunt casing and shunt ware, shunt casing sets up at the top of filter drum, shunt ware passes shunt casing and can move axially between filter position and blowdown position, when shunt ware is located filter position, the inner chamber of shunt ware is closed, the inner chamber of shunt casing is opened and is communicated with the inner chamber of filter drum, when shunt ware is located blowdown position, the inner chamber of shunt casing is closed, the inner chamber of shunt ware is opened and is communicated with the inner chamber of filter drum. The utility model can be convenient for realizing the switching of filter function and blowdown function, and can rotate through water flow drive scrape and wash subassembly to carry out automatic scraping and washing when discharging sewage, convenient and fast operation makes the cleaning difficulty of filter drum reduce greatly.
