[0033] A floor drain is a drainage structure installed on the ground to drain accumulated water. A floor drain typically consists of a drain body and a drain cover. The drain body is usually connected to a drainage pipe, and the drain cover covers the drain outlet of the drain body. The drain cover usually has several drainage holes. When the drain cover covers the drain outlet of the drain body, these drainage holes communicate with the drain outlet of the drain body for drainage. Currently, floor drain covers often lack structures to intercept hair. During drainage, hair easily flows with the water to the drainage holes of the drain cover and accumulates there or in the drain body's drain outlet, potentially clogging the drain filter's drainage holes or the drain body's drain outlet, thus reducing drainage efficiency.

[0034] Based on this, the present invention provides an embodiment of a floor drain filter 100, which is used to cover a floor drain cover 200 or a floor drain body, and can intercept hair, reduce the probability of blockage of the drain hole 2001 of the floor drain cover 200 or the drain outlet of the floor drain body, and improve drainage efficiency.

[0035] To facilitate the reader's understanding of the concept of this utility model embodiment, the specific structure of the floor drain filter 100 is described below:

[0036] Please see Figure 1 and Figure 2 The drain filter 100 includes a base plate 1 and a filter structure 2. The base plate 1 is used to cover the drain cover 200 or the drain body. The base plate 1 includes a ring 11 and a filter body 12. The filter body 12 is connected to the inner ring of the ring 11 and is provided with filter holes 121. When the base plate 1 covers the drain cover 200 or the drain body, the filter holes 121 are connected to the drain hole 2001 of the drain cover 200 or the drain outlet of the drain body. The filter structure 2 includes a plurality of first filter teeth 21. The plurality of first filter teeth 21 are evenly spaced along the periphery of the ring 11. The first filter teeth 21 are connected to the ring 11 and are set at a preset angle with the ring 11. The first filter teeth 21 are used to intercept hair in the water flow when the water flows from the ring 11 through the filter body 12. A first reserved space is formed between any two adjacent first filter teeth 21. The first reserved space is used to allow the water flow from the ring 11 to the filter body 12, reducing the impact on the normal flow of water.

[0037] In this way, when the water flows from the ring 11 to the filter body 12, the hair in the water can be wrapped or coiled around the first filter teeth 21, so that the first filter teeth 21 can effectively intercept the hair, reduce the accumulation of hair in the drain hole 2001 of the drain cover 200 or the drain outlet of the drain body, reduce the probability of blockage of the drain hole 2001 of the drain cover 200 or the drain outlet of the drain body, and improve drainage efficiency.

[0038] For the filter structure 2 described above, please refer to some embodiments. Figure 1 and Figure 2 The filter structure 2 also includes a plurality of second filter teeth 22, which are spaced apart along the periphery of the filter body 12. The second filter teeth 22 are connected to the filter body 12 and are set at a preset angle with the filter body 12. The second filter teeth 22 are used to intercept hair in the water flow when the water flows through the filter body 12. A second reserved space is formed between any two adjacent second filter teeth 22. The second reserved space is used to allow water to flow from the filter body 12 to the drain hole 2001 of the drain cover 200 or the drain outlet of the drain body, thereby reducing the impact on the normal flow of water.

[0039] In this way, when the water flows from the filter body 12 to the drain hole 2001 of the drain cover 200 or the drain outlet of the drain body, the hair in the water flow can be wrapped or coiled around the second filter teeth 22, so that the second filter teeth 22 can effectively intercept the hair, achieve secondary interception, further reduce the accumulation of hair in the drain hole 2001 of the drain cover 200 or the drain outlet of the drain body, further reduce the probability of blockage of the drain hole 2001 of the drain cover 200 or the drain outlet of the drain body, and further improve drainage efficiency.

[0040] In some embodiments, the first filter tooth 21 and the second filter tooth 22 have a preset angle of 90 degrees with the ring body 11, and the first filter tooth 21 is perpendicular to the ring body 11. Similarly, the second filter tooth 22 has a preset angle of 90 degrees with the filter body 12, meaning the second filter tooth 22 is perpendicular to the filter body 12. It is understood that the preset angles of the first filter tooth 21 and the second filter tooth 22 may include, but are not limited to, 90 degrees. For example, in other embodiments, the preset angles of the first filter tooth 21 and the second filter tooth 22 may be less than or greater than 90 degrees, as long as they are greater than zero degrees and less than 180 degrees.

[0041] Please see Figure 2 The drain filter 100 also includes a snap-fit ​​structure 3, which is connected to the side of the ring 11 opposite to the first filter teeth 21. The snap-fit ​​structure 3 is used to snap into the drain cover 200 or the drain body, so that the drain filter 100 is fixed to the drain cover 200 or the drain body. In this way, the drain filter 100 can be detachably connected to the drain cover 200 or the drain body.

[0042] For the snap-fit ​​structure 3 described above, please refer to some embodiments. Figure 2 and Figure 3 The snap-fit ​​structure 3 includes a first snap-fit ​​protrusion 31, which is at least partially spaced from the ring body 11. The first snap-fit ​​protrusion 31 and the ring body 11 enclose a first snap-fit ​​groove 311. The first snap-fit ​​protrusion 31 is used to penetrate a drain hole 2001 of the drain cover 200. (See also...) Figure 5When the first protrusion 31 penetrates the drain hole 2001 of the drain cover 200, the ring 11 rotates circumferentially along the ring body 11 so that the side wall of the drain hole 2001 of the drain cover 200 is engaged with the first slot 311. In this way, the drain filter 100 can be detachably connected to the drain cover 200, which facilitates quick installation and removal of the drain filter 100.

[0043] For easier understanding of the installation and removal process of the drain filter 100, please refer to [link / reference needed]. Figure 7 and Figure 8 This utility model provides an example: When installing the drain filter 100, firstly, the first locking protrusion 31 is made to penetrate a drain hole 2001 of the drain cover 200, and then the ring body 11 is rotated circumferentially so that the side wall of the drain hole 2001 of the drain cover 200 is engaged in the first locking groove 311, thereby allowing the drain filter 100 to cover the drain cover 200; conversely, when disassembling the drain filter 100, firstly, the ring body 11 is rotated circumferentially so that the side wall of the drain hole 2001 of the drain cover 200 is disengaged from the first locking groove 311, and then the first locking protrusion 31 is driven to disengage from the drain hole 2001 of the drain cover 200, thereby allowing the drain filter 100 to detach from the drain cover 200.

[0044] For details, please refer to Figure 3 The first protrusion 31 includes a first protrusion 312 and a first extension 313. One end of the first protrusion 312 is connected to the ring 11 along the thickness direction of the ring 11. The first extension 313 extends from the other end of the first protrusion 312 along the circumferential direction of the ring 11. The first extension 313 is spaced apart from the ring 11 along the thickness direction of the ring 11. The ring 11, the first protrusion 312 and the first extension 313 together form a first slot 311. The opening of the first slot 311 is opposite to the first protrusion 312.

[0045] Furthermore, in some embodiments, please refer to Figure 3 The ring body 11 is provided with a first through hole 111, which connects to a first slot 311 and is aligned with the bottom of the slot 311. When the side wall of a drain hole 2001 of the drain cover 200 is engaged in the first slot 311, the side wall of the drain hole 2001 is exposed in the first through hole 111. This allows the user to easily observe the engagement status of the first slot 311, adjust the engagement depth of the side wall of the drain hole 2001, and improve the reliability of the engagement.

[0046] For the snap-fit ​​structure 3 described above, please refer to some embodiments. Figure 2 and Figure 4The snap-fit ​​structure 3 includes a second snap-fit ​​protrusion 32, which is connected to the side of the ring body 11 opposite to the first filter tooth 21. The second snap-fit ​​protrusion 32 is at least partially spaced from the ring body 11. The second snap-fit ​​protrusion 32 and the ring body 11 enclose a second snap-fit ​​groove 321, which is opposite to the first snap-fit ​​groove 311. The opening of the second snap-fit ​​groove 321 is opposite to the opening of the first snap-fit ​​groove 311. The second snap-fit ​​protrusion 32 is used to penetrate another drain hole 2001 of the drain cover 200. (See also...) Figure 6 When the second protrusion 32 penetrates the drain hole 2001 of the drain cover 200, the ring body 11 is rotated circumferentially so that the side wall of the other drain hole 2001 of the drain cover 200 is engaged in the second slot 321. In this way, when the ring body 11 is rotated circumferentially, the side wall of one drain hole 2001 of the drain cover 200 is engaged in the first slot 311, and the side wall of the other drain hole 2001 of the drain cover 200 is engaged in the second slot 321. The two are engaged synchronously, realizing bidirectional rotational engagement, preventing loosening caused by unilateral engagement, and improving the engagement stability of the drain filter 100.

[0047] For easier understanding of the installation and removal process of the drain filter 100, please refer to [link / reference needed]. Figure 7 and Figure 8 This utility model provides another example: When installing the drain filter 100, firstly, the first locking protrusion 31 and the second locking protrusion 32 are simultaneously driven to penetrate the two drain holes 2001 of the drain cover 200 (e.g., two drain holes 2001 of the drain cover 200 that are opposite to each other or adjacent to each other). Then, the ring body 11 is rotated circumferentially so that the side walls of the two drain holes 2001 of the drain cover 200 are respectively engaged in the first locking groove 311 and the second locking groove 321, so that the drain filter 100 covers the drain cover 200. Conversely, when disassembling the drain filter 100, firstly, the ring body 11 is rotated circumferentially so that the side walls of the two drain holes 2001 of the drain cover 200 are respectively disengaged from the first locking groove 311 and the second locking groove 321. Then, the first locking protrusion 31 and the second locking protrusion 32 are simultaneously driven to disengage from the two drain holes 2001 of the drain cover 200, so that the drain filter 100 is detached from the drain cover 200.

[0048] For details, please refer to Figure 4 The second protrusion 32 includes a second protrusion 322 and a second extension 323. One end of the second protrusion 322 is connected to the ring 11 along the thickness direction of the ring 11. The second extension 323 extends from the other end of the second protrusion 322 along the circumferential direction of the ring 11. The second extension 323 is spaced apart from the ring 11 along the thickness direction of the ring 11. The ring 11, the second protrusion 322 and the second extension 323 together form a second slot 321. The opening of the second slot 321 is opposite to the second protrusion 322.

[0049] Furthermore, in some embodiments, please refer to Figure 4 The ring body 11 is provided with a second through hole 112, which is opposite to the first through hole 111. The second through hole 112 communicates with the second slot 321, and the bottom of the second through hole 112 is aligned with the bottom of the second slot 321. When the side wall of the other drain hole 2001 of the drain cover 200 is engaged in the second slot 321, the side wall of the other drain hole 2001 of the drain cover 200 is exposed in the second through hole 112. In this way, it is convenient for the user to observe the engagement status of the second slot 321, adjust the engagement depth of the side wall of the other drain hole 2001 of the drain cover 200, and improve the reliability of the engagement.

[0050] Please see Figure 1 and Figure 2 The drain filter 100 includes a handheld structure 4, which is connected to the ring body 11. The handheld structure 4 and the ring body 11 are set at a preset angle. The handheld structure 4 is used for the user to hold and rotate the ring body 11.

[0051] Regarding the handheld structure 4 described above, please refer to [link / reference] in some embodiments. Figure 1 and Figure 2 The handheld structure 4 includes a pull ring 41, which is connected to the ring body 11 and is set at a preset angle with the ring body 11. In this way, users can easily rotate or lift the ring body 11 by inserting their fingers into the inner ring of the pull ring 41, thereby rotating or lifting the drain filter 100.

[0052] Furthermore, in some embodiments, the surface of the pull ring 41 is provided with anti-slip texture. It is understood that the anti-slip texture includes, but is not limited to, striped textures, granular textures, diamond textures, or grid textures, etc. In this way, when a user inserts their finger into the inner ring of the pull ring 41, the contact friction between the user's finger and the pull ring 41 is increased, preventing slippage.

[0053] In some embodiments of the aforementioned drain filter 100, the ring body 11 and the filter body 12 are integrally formed; and / or, the first filter tooth 21 is integrally formed with the ring body 11; and / or, the second filter tooth 22 is integrally formed with the filter body 12; and / or, the first retaining protrusion 31 is integrally formed with the ring body 11; and / or, the second retaining protrusion 32 is integrally formed with the ring body 11; and / or, the pull ring 41 is integrally formed with the ring body 11. Through these methods, the overall structural strength can be improved, preventing loosening or detachment of local components during long-term use. Furthermore, through these methods, the integral forming process can reduce assembly steps, improve production efficiency, reduce production costs, and improve the consistency and durability of the finished product.

[0054] This utility model provides a drain filter 100, including a base plate 1 and a filter structure 2. The base plate 1 is used to cover a drain cover 200 or a drain body. The base plate 1 includes a ring 11 and a filter body 12. The filter body 12 is connected to the inner ring of the ring 11 and is provided with filter holes 121. When the base plate 1 covers the drain cover 200 or the drain body, the filter holes 121 are connected to the drain hole 2001 of the drain cover 200 or the drain outlet of the drain body. The filter structure 2 includes a plurality of first filter teeth 21. The plurality of first filter teeth 21 are evenly spaced along the periphery of the ring 11.
