[0002] In the traditional design of household swimming pool cleaner, the filter screen assembly is usually integrated in a whole structure, which is arranged between the upper and lower housings of the device. The feature of this design is that the filter screen is closely combined with its fixing part, and the filter screen is directly integrated into the fixing part as an embedded part through injection molding process in the manufacturing process, forming an integral structure that cannot be disassembled. However, such design has obvious limitations: 1. When the filter screen is damaged or needs to be cleaned due to use, the user cannot replace or clean the filter screen alone, but must replace it together with the fixed frame. This not only increases the maintenance cost, but also causes unnecessary waste of resources. 2. In the production link, since the filter screen needs to be placed in advance during injection molding, this process is low in efficiency, and in order to ensure correct installation of the filter screen, additional manual intervention is usually required. In addition, for the part beyond the outline of the filter screen fixing frame, manual trimming is often required, further increasing labor cost and time consumption. SUMMARY
