[0023] The technical scheme in the embodiment of the utility model will be clearly and completely described in combination with the drawings in the embodiment of the utility model, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skilled person in the art without paying creative labor belong to the protection scope of the utility model.

[0024] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, comprehensible and easily understandable, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0025] As shown in Figure 1 and 2 The present embodiment provides a filter screen, which comprises a filter screen basket 2 and a sliding block 3. The sidewall of the filter screen basket 2 is provided with a plurality of mesh holes, and the sliding block 3 is slidingly arranged in the filter screen basket 2.

[0026] In the specific embodiment, the filter screen basket 2 and the sliding block 3 are both made of ABS or stainless steel. The sliding block 3 can also be made of a metal material with higher density, such as copper or lead, to increase the kinetic energy of the sliding block 3 when it slides and improve the cleaning ability. In addition, a nylon outer layer can be arranged on the surface of the sliding block 3 to increase the slidability of the sliding block 3 in the filter screen basket 2 and prevent corrosion of the sliding block 3.

[0027] The top of the filter screen basket 2 is provided with a lifting ring 1, which is used to lift the filter screen basket 2.

[0028] The middle part of the sliding block 3 is provided with a through hole in the vertical direction.

[0029] The sliding block 3 has a convex structure, and the smaller diameter end of the sliding block 3 is arranged in the filter screen basket 2 in the upward direction.

[0030] The top and bottom of the filter screen basket 2 are respectively provided with inwardly extending limiting portions, which are used to prevent the sliding block 3 from falling out of the filter screen basket 2. The upper part of the sliding block 3 has a smaller diameter than the inner diameter of the limiting portion at the top of the filter screen basket 2.

[0031] In a more specific embodiment, the top limiting portion of the filter screen basket 2 comprises two protrusions, which are uniformly distributed along the circumference of the filter screen basket 2. The minimum distance between the two protrusions is greater than the upper diameter of the sliding block 3 but less than the lower diameter of the sliding block 3, so that the upper part of the sliding block 3 protrudes out of the filter screen basket 2, thereby facilitating the complete cleaning of the hair 4 in the filter screen basket 2. The bottom limiting portion of the filter screen basket 2 comprises an annular flange, and the inner diameter of the annular flange is less than the diameter of the bottom of the sliding block 3.

[0032] The height of the conventional filter screen is relatively small, and the capacity for storing sundries is also relatively small. In the specific embodiment, the height of the filter screen basket 2 is greater than 50 mm, which can accommodate the sliding block 3 and also accommodate more hair 4.

[0033] The mesh holes are circular holes or oblong holes. The size of the mesh holes is 4-8 mm.

[0034] The initial state after the filter screen is installed, the slider 3 is located at the bottom of the filter screen basket 2, when the hair 4 is accumulated too much and needs to be cleaned, the filter screen basket 2 is inverted, the slider 3 slides downward under the action of gravity, and stops sliding under the limiting action of the limiting part of the filter screen basket 2, and the hair 4 is pushed out. If there are a few residual hairs 4 in the filter screen basket 2, the filter screen can be shaken up and down quickly, so that the slider 3 slides back and forth in the filter screen basket 2, and the remaining hair 4 is taken out.

[0035] It should be noted that for those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application, and any reference signs in the claims should not be regarded as limiting the claims.
