[0006] Furthermore, the inlet pipe is provided with an internal thread, and the bottom end of the ceramic filter element is provided with an external thread matching the internal thread.

[0007] Furthermore, a positioning column is fixedly connected to the outer periphery of the water inlet, and the positioning column is rotatably sleeved on a limiting column, and the limiting column abuts against the connection cover.

[0008] Furthermore, the limiting column is in an inverted L-shape.

[0009] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effects of the utility model include:

[0010] Water enters the water inlet from the inner water pipe, and enters the inner water pipe from the inlet pipe after being filtered by the ceramic filter element. After using it for a period of time, separate the water inlet and the connecting cover, rotate the ceramic filter element in the opposite direction to remove it, scrub the outer wall of the ceramic filter element to remove impurities intercepted by the ceramic filter element, and then re-screw and connect the ceramic filter element to facilitate disassembly, cleaning and replacement of the filter mechanism.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, other implementation methods or equivalent replacements obtained by those skilled in the art without creative work are all within the scope of protection of the utility model.

[0015] like Figure 1-2 As shown, a filtering device for an ice maker comprises an ice maker housing 1, a door panel is rotatably connected to the upper front section of the ice maker housing 1, an evaporator movable shaft 2 is movably installed at the middle position of the inner top of the ice maker housing 1, an evaporator 3 is installed on the evaporator movable shaft 2, an ice-making mold 4 is installed below the evaporator 3, a water inlet 5 is arranged at the rear top of the ice maker housing 1, the water inlet 5 is connected to an inner water pipe 7 through an inlet pipe 6, a water supply valve 8 is installed on the inner water pipe 7, a ceramic filter element 9 is threadedly connected to the inlet pipe 6, the water inlet 5 is magnetically attracted to the connecting cover 10, and the connecting cover 10 is magnetically attracted to the water inlet 5. 0 is connected to an external water pipe 11, and the other end of the external water pipe is connected to bottled water; a switch is installed at the front middle position of the ice maker housing 1, and the water supply valve 8, the evaporator movable shaft 2, and the evaporator 3 are all electrically connected to the switch; when the water supply valve 8 is started, water enters the water inlet 5 from the inner water pipe 7, and enters the inner water pipe 7 from the inlet pipe 6 after being filtered by the ceramic filter element 9; after using for a period of time, the water inlet 5 and the connecting cover 10 are separated, and the ceramic filter element 9 is removed by twisting in the opposite direction, and the outer wall of the ceramic filter element 9 is scrubbed with sandpaper to remove impurities intercepted by the ceramic filter element 9.
