[0003] For example, the self-cleaning filter disclosed in CN211659434U has the following technical solutions: it comprises a filter cartridge and a filter core cartridge inserted in the filter cartridge and arranged co-core therewith, end caps being provided at both ends of the filter core cartridge, the inner wall of the filter cartridge, the outer wall of the filter core cartridge and the end caps at both ends enclose a storage area for the liquid to be filtered, and the end caps at both ends and the inner wall of the filter core cartridge enclose a filtrate storage area; a liquid inlet pipe with a valve is provided on the end cap located in the liquid storage area for the liquid to be filtered and / or the cylinder wall of the filter cartridge, and a liquid outlet pipe with a valve is provided on the end cap located in the filtrate storage area, the liquid to be filtered enters from the liquid inlet pipe, is filtered through the filter core cartridge and then flows out from the liquid outlet pipe; and the liquid outlet pipe is arranged in parallel with the liquid outlet pipe. A cleaning liquid inlet pipe with a valve is provided on the end cover, and a driving impeller is provided at the end of the filter cartridge near the cleaning liquid inlet pipe. The cleaning liquid sprayed from the cleaning liquid inlet pipe drives the driving impeller to rotate and drives the filter cartridge to rotate around its core line. A cleaning liquid output pipe with a valve is also provided on the end cover and / or the cylinder wall of the filter cartridge in the liquid storage area to be filtered for the cleaning liquid to flow out. It mainly realizes the unpowered self-cleaning of the filter by pumping cleaning liquid into the filter through the setting of additional pipelines. Moreover, the flow path of the cleaning liquid is opposite to the flow path during normal filtration. Combined with the self-rotation of the filter cartridge, it can not only improve the efficiency of self-cleaning, but also achieve better self-cleaning effect.

[0004] The above-mentioned self-cleaning filter still has certain shortcomings: since the self-cleaning filter works in an external environment, once the surface of the motor gear inside the self-cleaning filter is rusted, it will affect the operation of the motor. At the same time, it will be inconvenient to maintain it, which reduces the practicality of the device. Therefore, it is necessary to provide an easy-to-maintain self-cleaning filter.
