Description

A filter for intercepting debris Technical Field

[0001] This application relates to the technical field of debris filtration, and in particular to a filter for intercepting debris. Background Technology

[0002] Floor drains are installed at the drain outlets in many places for drainage purposes, such as in bathrooms. After a long period of drainage, debris will accumulate in the floor drain and need to be cleaned. Hair is a common culprit in bathrooms, and the filter structure of the floor drain makes it inconvenient to clean it quickly after a lot of debris has accumulated.

[0003] Therefore, this application provides a filter for intercepting debris to solve the problem mentioned. Summary of the Invention

[0004] To address the aforementioned problems, this application provides a filter for intercepting debris.

[0005] The filter for intercepting debris provided in this application adopts the following technical solution:

[0006] A filter for intercepting debris includes a base, an annular groove at the top of the base, and multiple openings at the bottom of the base. Magnets are fixedly embedded in the openings. An annular wire is placed in the annular groove, and a sleeve is fitted on the annular wire. A mesh bag is fixedly installed inside the side of the sleeve. The base is installed above a floor drain, and the mesh bag is placed inside the floor drain, replacing the original filter structure of the floor drain. It can filter debris such as hair and is easy to clean.

[0007] In one embodiment, an arc-shaped frame is provided on the annular wire. The arc-shaped frame is located outside the sleeve, and the arc-shaped frame and the annular wire are integrally formed, which facilitates the removal of the mesh bag.

[0008] In one embodiment, the plurality of bottom openings are evenly distributed and arranged in a ring, with the bottom openings located directly below the annular groove, so that the annular wire can be stably positioned within the annular groove.

[0009] In one embodiment, counterweights are fixedly installed at each of the four corners of the base to ensure overall stability and prevent it from being washed away by water.

[0010] In one embodiment, the bottom of the mesh bag is provided with a support block, which can increase the water passage space and prevent hair and other debris from accumulating at one point and obstructing the drainage. The support block can be placed in the drainage groove of the original floor drain. When there is no drainage groove, the support block is not needed.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] The base is placed above the drain outlet, and the counterweight enhances the overall stability and prevents it from being washed away by water. The ring-shaped wire is threaded inside the sleeve and can be attracted to the ring groove by the magnetic block. The mesh bag is placed inside the drain, replacing the original filter structure of the drain. It can filter out small debris such as hair. The mesh bag can be picked up and turned over for cleaning through the arc frame. The operation is simple. Attached Figure Description

[0015] Explanation of reference numerals in the attached drawings: 1. Base; 2. Support block; 11. Annular groove; 12. Annular wire; 13. Sleeve; 14. Arc frame; 15. Bottom opening; 16. Magnet block; 17. Mesh bag; 18. Counterweight block. Detailed Implementation

[0016] The present application will be further described in detail below with reference to Figures 1 and 2.

[0017] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown in the drawings have been exaggerated or reduced in size; any dimensions are merely exemplary and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0018] This application discloses a filter for intercepting debris.

[0019] A filter for intercepting debris includes a base 1, an annular groove 11 on the top of the base 1, and multiple bottom openings 15 on the bottom of the base 1. A magnet 16 is fixedly embedded in the bottom opening 15. An annular wire 12 is arranged in the annular groove 11. A sleeve 13 is fitted on the annular wire 12. A mesh bag 17 is fixedly installed inside the side of the sleeve 13. The base 1 is installed above a floor drain, and the mesh bag is placed inside the floor drain, replacing the original filter structure of the floor drain. It can filter debris such as hair and is easy to clean.

[0020] An arc-shaped frame 14 is provided on the annular wire 12. The arc-shaped frame 14 is located outside the sleeve 13. The arc-shaped frame 14 and the annular wire 12 are integrally formed, which makes it convenient to take out the mesh bag 17.

[0021] The multiple bottom openings 15 are evenly distributed and arranged in a ring. The bottom openings 15 are located directly below the annular groove 11, which allows the annular wire 12 to be stably located in the annular groove 11.

[0022] Counterweights 18 are fixedly installed at the four corners of the base 1 to ensure overall stability and prevent it from being washed away by water.

[0023] The bottom of the mesh bag 17 is equipped with a support block 2, which can increase the water passage space and prevent hair and other debris from accumulating in one place and obstructing the drainage. The support block 2 can be placed in the drainage groove of the original floor drain. When there is no drainage groove, the support block 2 is not needed.

[0024] All standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the instructions and drawings. The connection methods of each part adopt mature conventional methods such as bolts, rivets, and welding. The machinery, parts and equipment all adopt conventional models, and the circuit connection adopts conventional connection methods, which will not be described in detail here.

[0025] The implementation principle of a filter for intercepting debris in this application embodiment is as follows: When in use, the base 1 can be placed above the drain outlet. The overall stability is improved by the counterweight 18 to prevent it from being washed away by water. The annular wire 12 is threaded inside the sleeve 13 and can be attracted to the annular groove 11 under the action of the magnet 16. The mesh bag 17 is placed inside the drain, replacing the original filter structure of the drain. It can filter out small debris such as hair. The mesh bag 17 can be picked up and turned over for cleaning by the arc frame 14. The operation is simple.

[0026] Finally, several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, internal communication between two components, or direct connection.
