When the drain filtration device 100 is used in other equipment, it should also fall within the protection scope of this utility model.

[0043] The aforementioned drain filtration device 100 includes a filter assembly and a connector 2. The filter assembly includes a filter screen 11, which has a retracted state and an extended state, and can switch between the two states. The connector 2 is movably connected to the filter screen 11. When the filter screen 11 is in the retracted state, the connector 2 is connected to the filter screen 11; when the filter screen 11 is in the extended state, the connector 2 is separated from the filter screen 11. The washing machine has a washing tub and a drain channel communicating with the washing tub. The drain filtration device 100 is detachably mounted on the side wall of the washing tub. After washing, the wastewater in the washing tub is first filtered by the drain filtration device 100, and the filtered water is discharged through the drain channel to prevent impurities in the wastewater from clogging the sewer. When cleaning the drainage filter device 100, the drainage filter device 100 is removed and the filter screen 11 is separated by the connector 2, thereby unfolding the filter screen 11. The unfolded filter screen 11 has no dead corners for cleaning, avoiding the situation where the existing filter screen 11 is clogged due to the inconvenience of cleaning the lint at the corners, thus affecting the filtration effect and optimizing the user experience.

[0044] The drainage filtration device 100 of this utility model is movably connected to the filter screen 11 by a connecting member 2. When the connecting member 2 is connected to the filter screen 11, the filter screen 11 is in a retracted state, and the connecting member 2 can keep the filter screen 11 in a retracted state, ensuring the filtration effect of the filter screen 11. During filtration, sewage flows through the filter screen 11, and the side wall of the filter screen 11 can filter lint. When it is necessary to clean the filter screen 11, the drainage filtration device 100 is removed and the connecting member 2 is separated from the filter screen 11, thereby unfolding the filter screen 11. The unfolded filter screen 11 has no dead corners for cleaning, making it easy for users to clean the lint on the filter screen 11, saving time and effort, improving the filtration effect and efficiency of the drainage filtration device 100, and providing a better user experience.

[0045] In some embodiments of this utility model, the filter screen 11 includes multiple filter sections that can be connected in a retractable manner, and a groove 12 is provided between two adjacent filter sections, allowing two adjacent filter sections to be folded along the groove 12. In this embodiment, the filter screen 11 is made of PP (polypropylene) or ABS (Acrylonitrile Butadiene Styrene). The filter screen 11 is integrally injection molded and includes three filter parts, namely a first filter part 111, a second filter part 112, and a third filter part 113 connected in sequence. A groove 12 is provided between two adjacent filter parts. Each filter part is rectangular in shape and has a certain thickness. On the one hand, this ensures the overall strength of the filter screen 11, and on the other hand, it facilitates the setting of the groove 12 at the connection between two adjacent filter parts. Each filter part is provided with multiple first filter holes 14. The three filter parts are arranged in sequence. By providing the groove 12, it is easy for the filter parts to close, so that the filter screen 11 is in a closed state. In the closed state, the cross-sectional shape of the filter screen 11 is U-shaped.

[0046] In other embodiments, the number, shape, and thickness of the filter sections can be set according to actual needs, and each filter section can also be a separate structure.

[0047] In some embodiments of this utility model, the connector 2 includes a first cover 21 with a water inlet 211. A connecting structure is provided between the first cover 21 and the filter screen 11. The connecting structure includes a connecting part 7 on the first cover 21 and a connecting mating part 3 on the filter screen 11, with the connecting part 7 and the connecting mating part 3 engaging. The water inlet 211 communicates with the washing tub. During filtration, wastewater enters the filter screen 11 through the water inlet 211 and flows out after being filtered by the filter screen 11. The connecting part 7 on the first cover 21 and the connecting mating part 3 on the filter screen 11 facilitate the assembly and disassembly of the first cover 21 and the filter screen 11.

[0048] In some embodiments of this utility model, the connecting part 7 includes one of a protrusion 31 and a groove 71, and the connecting mating part 3 includes the other of a protrusion 31 and a groove 71. The groove 71 and the protrusion 31 are slidably connected. In this embodiment, the first cover 21 is provided with two grooves 71, which are respectively located on both sides of the first cover 21 and extend along the length of the first cover 21. The filter screen 11 is provided with two protrusions 31, which are respectively located on both sides of the filter screen 11 and extend along the length of the filter screen 11. The two protrusions 31 are correspondingly provided with the two grooves 71. When connecting the first cover 21 and the filter screen 11, the sliding groove 71 on the first cover 21 and the protrusion 31 on the filter screen 11 slide together to connect the first cover 21 and the filter screen 11, and limit the sliding of the first cover 21, so that the first cover 21 and the filter screen 11 can be detached and connected.

[0049] In other embodiments, a protrusion 31 may be provided on the first cover 21, and a groove 71 may be provided on the filter screen 11. The number and arrangement of the groove 71 and the protrusion 31 may also be set according to requirements. In addition, the connecting part 7 and the connecting mating part 3 may also be set as a snap-fit ​​structure or a nested structure, etc.

[0050] In some embodiments of this utility model, the drainage filtration device 100 further includes a cleaning component. The connector 2 is connected to the filter screen 11 and forms a filter cavity 13. The cleaning component is disposed within the filter cavity 13 and is used to clean the filter screen 11. Specifically, the first cover 21, the first filter part 111, the second filter part 112, and the third filter part 113 form the filter cavity 13. The filter cavity 13 extends along the sliding direction of the first cover 21. The cleaning component is disposed within the filter cavity 13 and is connected to the first cover 21. When the first cover 21 slides along the filter screen 11, the cleaning component connected to the first cover 21 moves along the filter screen 11 and can remove impurities on the filter screen 11 along the moving path, further improving the convenience and cleaning efficiency of cleaning the filter screen 11.

[0051] In some embodiments of this utility model, the cleaning component includes at least one cleaning brush 4. The cleaning brush 4 includes an installation part 41 and a cleaning part 42 connected to each other. The installation part 41 is connected to the connector 2, and the cleaning part 42 abuts against the inner end face of the filter screen 11. Specifically, there are multiple cleaning brushes 4, each of which includes an installation part 41 and a cleaning part 42. The installation part 41 includes a brush rod 411, and the cleaning part 42 includes a brush head 421. One end of the brush rod 411 is connected to the first cover 21, and the other end is connected to the brush head 421. The brush head 421 abuts against the inner wall of the second filter part 112. When the first cover 21 slides along the filter screen 11, the cleaning brush 4 moves along the length direction of the filter screen 11, thereby causing the brush head 421 to brush away impurities on the filter screen 11.

[0052] In other embodiments, a cleaning brush 4 for cleaning the first filter section 111 and the third filter section 113 may be provided, or a cleaning brush 4 with a brush head 421 arranged along the length direction perpendicular to the filter screen 11 may be provided, and the number and arrangement position of the cleaning brush 4 may be set according to actual needs.

[0053] In some embodiments of this utility model, the drainage filtration device 100 further includes a second cover 5. The filter chamber 13 has an open end, and the second cover 5 is movably connected to the open end so that the second cover 5 can open or close the open end. Alternatively, the second cover 5 has a through-hole 51 that communicates with the filter chamber 13. In this embodiment, the second cover 5 and the filter screen 11 are integrally formed. The second cover 5 is hinged to the second filter section 112, allowing the open end of the second cover 5 to be opened or closed. Specifically, when filtration is performed, the second cover 5 is closed relative to the open end. At this time, sewage flows out of the filter screen 11 through the first filter hole 14 or the second filter hole 51, or the first filter hole 14 and the second filter hole 51. By providing the second filter hole 51 on the second cover 5, the filtration volume of the drainage filtration device 100 can be increased, improving the filtration efficiency. When cleaning the filter screen 11, the filter screen 11 is unfolded, and the second cover 5 is opened relative to the open end, meaning the filter screen 11 is in an unfolded state, facilitating cleaning. The second cover 5 is provided with a buckle (not shown in the figure), and the first cover 21 is provided with a slot (not shown in the figure) at one end near the second cover 5. The buckle and the slot are connected to each other so that the second cover 5 and the first cover 21 can be movably connected, making it easy to open or close the second cover 5.

[0054] In other embodiments, the second cover 5 and the filter screen 11 can also be configured as a separate structure. In this structure, the second cover 5 can be hinged to the filter screen 11 via a pivot to open or close the second cover 5.

[0055] In some embodiments of this utility model, the filter assembly further includes a filter support 6, on which a limiting structure 62 is provided. When the filter screen 11 is in a retracted state, the limiting structure 62 is used to limit the filter screen 11. In this embodiment, the rotating support and the filter screen 11 are an integral structure. The limiting structure 62 includes two limiting grooves 621 provided at one end of the filter support 6 facing the filter screen 11. The shape of the limiting grooves 621 is adapted to the edge shape of the filter screen 11, so that when the filter screen 11 is in a retracted state, the edge of the filter screen 11 abuts against the limiting grooves 621, and is fixed by the first cover 21, thereby achieving a stable structure for the filter screen 11. This effectively prevents the filter screen 11 from unfolding during operation, improving the stability and reliability of the filter assembly. A rotating part 61 is provided at the end of the filter bracket 6 away from the filter screen 11, and a rotating mating part (not shown in the figure) is provided on the side wall of the washing tub. The drain filter device 100 is rotatably connected to the side wall of the washing tub through the filter bracket 6. When installing the drain filter device 100, the filter bracket 6 is rotated so that the rotating part 61 rotates relative to the rotating mating part to connect the filter bracket 6 to the side wall of the washing tub. When disassembling the drain filter device 100, the filter bracket 6 is rotated in the opposite direction to separate the rotating part 61 from the rotating mating part, thereby switching the filter bracket 6 from the connected state to the separated state, which facilitates the overall assembly and disassembly of the drain filter device 100.

[0056] A second aspect of this invention provides a garment processing device, including the aforementioned drain filter device 100. During the washing process, the drain filter device 100 filters and collects floating objects such as lint in the washing water. After washing, the washing machine's drainage system is opened, and the washing water enters the drainage system and is discharged from the washing machine through the drain filter device 100 and the drainage channel. At the same time, the drain filter device 100 collects any remaining lint and other impurities in the washing machine drum.
