The cleaning component 3 allows the device to clean the internal filter screen. Two sets of snap-fit ​​components 4 are provided inside the housing 1, facilitating the replacement of the filter layer 5. The housing 1 contains a filter layer 5. The cleaning component 3 includes components fixedly connected to the top surface of the sealing cover 2. The servo motor 301 has a rotating rod 302 fixedly connected to one end. Four sets of telescopic rods 303 are fixedly connected to the outside of the rotating rod 302. Each of the four sets of telescopic rods 303 is fitted with a telescopic spring 304. One end of each of the four sets of telescopic springs 304 is fixedly connected to two sets of brush rods 305. The two sets of snap-fit ​​components 4 are both set inside the outer shell 1 and are sliding plates 401. Each of the two sets of sliding plates 401 is fitted with a compression spring 402. Each of the two sets of sliding plates 401 is fixedly connected to one side of a snap-fit ​​rod 403.

[0025] Two sets of clips 6 are fixedly connected to the outside of the filter layer 5. Both sets of clips 6 have insertion holes inside. The clips 6 are used to fix the filter layer 5.

[0026] A water inlet pipe 7 is fixedly connected to one side of the outer casing 1, and a first connecting plate 9 is fixedly connected to one end of the water inlet pipe 7. The water inlet pipe 7 serves to allow water to enter.

[0027] A water outlet pipe 10 is fixedly connected to the other side of the outer casing 1. A second connecting plate 11 is fixedly connected to one end of the water outlet pipe 10. The water outlet pipe 10 serves to discharge the filtered water.
