Firstly, we need to release the upper clip so that we can operate conveniently. Using water pressure can help us flush out the top connecting pipe. This step is crucial because the top connecting pipe may have adhered impurities that need to be cleaned thoroughly before further operation.
Next, we can remove the cleaning pipe section. This process may require some effort as the old filter may contain a lot of dirt and needs to be carefully extracted. Additionally, there may be contaminants inside the stainless steel body, which we need to flush with water to ensure it is clean and free of foreign objects.
After preparing the new filter, we can insert it into the stainless steel body. Ensure that the filter is positioned correctly to ensure optimal filtering performance.
首先，我们需要解开上方夹子，这样才能方便操作。使用水的压力，可以帮助我们把顶部连接管冲出去。这个步骤很关键，因为顶部连接管附着了一些杂质，需要清除干净才能进一步操作。
接着，我们就可以取出清洗管的部分了。这个过程可能会有些费力，因为旧的滤芯里面会有很多污垢，需要小心翼翼地取出来。同时，不锈钢机身内部也可能残留有污染物，我们需要用水冲洗，确保里面干净无异物。
准备好新的滤芯后，我们就可以插入到不锈钢机身里了。确保滤芯的位置正确，这样可以保证过滤效果达到最佳状态。
Furthermore, the battery of the automatic cleaning valve also needs to be replaced because an aged battery can cause the automatic cleaning function to fail. If the battery shows signs of rust, it needs to be cleaned, and a new battery should be installed. If the battery cover is lost, we also need to find a suitable part to fill the hole to prevent water from seeping into the battery and affecting the normal operation of the automatic cleaning valve.
After completing these steps, we can test the effectiveness of the new filter and ensure that the automatic cleaning function is restored to normal. This way, the outdoor filter completes the filter replacement and maintenance work.
另外，自动清洗阀的电池也需要更换，因为老化的电池会导致自动清洗功能失效。如果发现电池已经生锈，需要将其清除，并安装上新的电池。如果电池盖丢失了，我们也需要找到合适的零件填补回这个洞口，避免水渗入电池内部，影响自动清洗阀的正常工作。
完成这些步骤后，我们就可以测试一下新滤芯的效果，并确保自动清洗功能恢复正常。这样，户外过滤器就完成了滤芯更换和维护工作。
