[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure for protection, but merely represents selected embodiments of the present disclosure.

[0019] In the description of this disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this disclosure, "plurality" means two or more, unless otherwise specifically specified.

[0020] Example 1

[0021] Reference Figure 1-3 As shown, the embodiment of the present disclosure provides a filter screen for a floor drain, comprising:

[0022] The first spoke 1 is arranged along a diameter of the filter screen.

[0023] The first through hole and the filter screen are in a fishbone shape. The second spokes 2 are respectively arranged on both sides of the first spoke 1. The second spokes 2 are arranged in parallel with each other. The second spokes 2 are arranged in a direction perpendicular to the first spokes 1.

[0024] The second spokes 2 on both sides are arranged symmetrically or asymmetrically.

[0025] First through holes 3 are formed between adjacent second spokes 2 on the same side. That is, a plurality of first through holes 3 are provided on both sides of the first spoke 1.

[0026] The first spoke 1 and the second spoke 2 are an integrated structure, which can provide support strength for the filter screen when it is laid flat for passing water and loading debris.

[0027] The first through holes 3 separated by the second spokes 2 are in the shape of long strips with a large aspect ratio, and can have a good ability to intercept debris. At the same time, the water flow area is large and can have a good water flow speed.

[0028] The first concave portion 6 is arranged along the circumferential direction. The first concave portion 6 is concave from a first diameter to a second diameter, wherein the first diameter is greater than the second diameter.

[0029] In some embodiments, the first diameter is the diameter of the filter screen.

[0030] The first recessed portion 6 forms a sloped structure around the periphery of the filter. Circumferentially, the slope is annular and separated by first through-holes 3. Radially, the slope can be arc-shaped or linear. The slope guides water flow into the filter, allowing debris carried by the water to be collected at the bottom of the slope, facilitating subsequent cleaning.

[0031] Furthermore, in some embodiments, the filter screen includes a second recessed portion 7 recessed from the third diameter to a fourth diameter, and the second recessed portion 7 is arranged along the circumferential direction, wherein the fourth diameter is smaller than the third diameter, the fourth diameter is larger than the third diameter, and the fourth diameter is not larger than the second diameter.

[0032] In some embodiments, the third diameter is 0, that is, the second concave portion 7 is concave from the center of the circle toward the surrounding area, and the formed second concave portion 7 is hemispherical.

[0033] The second concave portion 7 forms another slope structure inside the filter near the center, opposite to the first concave portion 6. Similarly, in the circumferential direction, the slope structure is annular and separated by the first through hole 3. In the radial direction, the slope structure can be arc-shaped or straight-line.

[0034] In some embodiments, the cross-section of the filter screen along any diameter is W-shaped.

[0035] In some embodiments, the fourth diameter is smaller than the second diameter, thereby forming an annular plane area 8 between the third diameter and the second diameter. The annular plane area 8 is used to collect debris in the water.

[0036] The second recess 7 prevents debris from concentrating in the center of the filter, which could lead to complete blockage and impaired drainage. The recessed structure formed by the second recess 7 and the first recess 6 disperses debris over the annular planar area 8, reducing the amount of debris covering each portion of the first through hole 3 during use, thereby maintaining a stable drainage volume.

[0037] Furthermore, in some embodiments, the filter screen includes a central through hole 4 , which is disposed at the center of the filter screen, that is, on the first spoke 1 .

[0038] The central through hole 4 is set at a high point of the slope structure, which can reduce the possibility of being covered by debris, and its circular or semicircular hole cross-section can reduce the water flow from completely blocking the hole, so that it can be used for air circulation above and below the filter screen, avoiding the situation where the filter screen is completely blocked and cannot be put into the water due to the lack of air pressure difference between the upper and lower parts.

[0039] The central through hole 4 can also be used for inserting fingers into and gripping the filter screen for movement.

[0040] Furthermore, in some embodiments, the central through hole 4 is provided with a partition 5 along a diameter.

[0041] The partition 5 can be easily clamped or hooked to avoid touching the filter with fingers, which may cause health risks. In particular, the bottom surface of the filter is less flushed by water than the top surface, making it more likely to breed bacteria.

[0042] In some embodiments, the top surface of the filter is provided with a raised portion 11. The raised portion 11 is also used for clamping the filter with a clamp or fingers to move and clean the debris trapped on the filter.

[0043] In some embodiments, a first bracket 9 is provided on the bottom surface of the filter screen along the circumference of the fifth diameter.

[0044] The first bracket 9 is used to be placed at the corresponding installation position on the floor drain. On the one hand, it can play a certain limiting role and abut against the side of the installation position. On the other hand, it can increase the contact area with the floor drain to avoid the arc structure of the filter screen directly contacting the floor drain and lacking stability.

[0045] In some embodiments, a second bracket 10 is provided at the bottom of the first spoke 1. The second brackets 10 at both ends of the first spoke 1 are arranged opposite each other. The second brackets 10 are used to be placed at corresponding mounting positions further outward on the floor drain, thereby providing a similar limiting and stabilizing effect.

[0046] That is, the second bracket 10 plays a role in limiting the position of the filter screen installed on the floor drain and providing stable support in another radial dimension. And its volume is larger, so its role is more obvious.

[0047] The present disclosure also provides a floor drain comprising the filter described in any of the above embodiments. The filter is installed on the floor drain to pass water and intercept debris carried in the water to prevent the debris from clogging the floor drain and its connected pipes.

[0048] Users can clean the filter regularly, such as by removing it and cleaning it, to avoid excessive debris clogging the filter and affecting water flow.

[0049] The foregoing description is merely a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
