The specific embodiments are as follows:

[0028] Embodiment 1

[0029] The disc cover 10 has a through opening, and the cylinder 20 is fixedly connected to the disc cover 10 .

[0030] The water inlet assembly 40 includes a lower cover plate 41 arranged at the bottom of the cylinder 20 and a partition plate 42 fixedly connected to the cylinder 20. A water inlet pipe 43 is arranged on the lower cover plate 41, and water is injected into the cylinder 20 through the arranged water inlet pipe 43. Preferably, the water inlet pipe 43 is a hose.

[0031] A filter assembly 30 is disposed in the inner cavity of the cylinder 20 , and a water outlet pipe 21 is disposed on one side of the cylinder 20 . The water outlet pipe 21 is located on the upper side of the filter assembly 30 , and filtered water is discharged through the water outlet pipe 21 .

[0032] The partition 42 and the inner wall of the cylinder 20 form a water-conducting annular gap, a lower arc surface 411 is arranged on the upper side of the lower cover plate 41, an upper arc surface 421 is arranged on the lower side of the partition 42, a magnetic attraction layer is laid on the lower arc surface 411, and the upper arc surface 421 and the lower arc surface 411 have a gap for water flow, so that water enters the gap through the water inlet pipe 43 and flows into the gap, where the iron filings contained in the magnetic attraction layer are attracted, and then flows upward through the water-conducting annular gap and is filtered by the filter assembly 30, thereby realizing the separate filtration of iron filings and other impurities during the water purification process, avoiding blockage in a short time, effectively reducing the maintenance frequency, and achieving high water output efficiency.

[0033] The motion component 50 is used to drive the upper cover plate 22 to seal or open the cylinder 20. The motion component 50 includes an electric cylinder body 51 and a telescopic rod 52 arranged on the disc cover 10. The movable rod of the electric cylinder body 51 is connected to the lower cover plate 41, and the movable end of the telescopic rod 52 is connected to the lower cover plate 41. A rubber ring is arranged on the lower cover plate 41, and the rubber ring can contact the inside of the cylinder 20 to improve the sealing effect and prevent water leakage.

[0034] When the motion component 50 drives the upper cover plate 22 to block the cylinder 20 , water is filtered. When the motion component 50 drives the upper cover plate 22 to open the cylinder 20 , maintenance operations are performed on the magnetic attraction layer.

[0035] Embodiment 2

[0036] The filter assembly 30 includes a ring body 31 fixed to the inner wall of the cylinder 20 , a filter screen 32 is placed on the ring body 31 , an upper cover plate 22 is screwed to the top of the cylinder 20 , a pressure ring 23 is arranged on the lower side of the upper cover plate 22 , and the pressure ring 23 can be against the filter screen 32 .

The pressure ring 23 can abut against the filter screen 32 , so that the filter screen 32 can be stably placed on the ring body 31 .

[0038] The upper arc surface 421 and the lower arc surface 411 have the same shape, and are inclined downward and outwardly expanded. The upper arc surface 421 is provided with multiple side plates 44, which can contact the lower arc surface 411, and two adjacent side plates 44 can form a drainage channel connected to the water guide annular gap.

[0039] Water flows between the upper arc surface 421 and the lower arc surface 411 through multiple drainage channels, effectively improving the magnetic attraction effect of the magnetic attraction layer on the iron filings contained in the water. After the moving component 50 drives the lower cover plate 41 to open the cylinder 20, the lower cover plate 41 leaves the multiple side plates 44 and is exposed. At this time, the iron filings attracted by the magnetic attraction layer can be cleaned conveniently, and the iron filings can be scraped off along the downwardly inclined and outwardly expanding lower arc surface 411.
