[0002] A filter is a device used to filter out unnecessary substances. It is often used to filter out unnecessary impurities when transporting liquids or solids such as sand and gravel. In the process of transporting liquids through pipelines, filters are often used to remove solid impurities. When the liquid flows through the filter, the impurities in it are filtered out, which can protect the normal operation of pumps, compressors, instruments and other components.

[0003] The filter is provided with a filter screen. When the liquid passes through the filter screen, the substances in the liquid that are larger than the filter screen will be blocked by the filter screen and cannot block the filter delivery port as the liquid continues to be delivered. Most of the existing filters are integrated. When the filter needs to be cleaned, it is necessary to manually insert a cleaning tool into the filter for cleaning. However, there are the following problems in the existing filter that is easy to clean and maintain:

[0004] When cleaning the existing filter, it is first necessary to manually open the filter cover, and then insert the cleaning tool into the filter for cleaning.
