[0039] like Figures 1 to 6 As shown, this embodiment provides a drainage filter comprising an outer shell 1, an inner liner 2, and a cage 3. The outer shell 1 is disposed at the bottom of a tank body 100, and a water outlet 11 is provided at the bottom of the outer shell 1. The inner liner 2 is disposed within the outer shell 1, and an anti-blocking flow channel 21 is formed between the inner liner 2 and the outer shell 1. The sidewalls of the inner liner 2 are provided with a water hole 22 and a drainage hole 23. The water hole 22 communicates with the anti-blocking flow channel 21, and the drainage hole 23 is located below the water hole 22. The cage 3 is movably disposed within the outer shell 1 and within the inner liner 2. The cage 3 has a water storage position and a water discharge position. In the water storage position, the cage 3 isolates the inner cavity of the cage 3 from the water outlet 11. In the drainage position, the cage 3 connects the inner cavity of the cage 3 with the water outlet 11. When the cage 3 is blocked, water in the tank body 100 can enter the anti-blocking flow channel 21 through the water hole 22 and then be discharged through the water outlet 11.

[0040] When the user needs to store water, the cage 3 is placed in the water storage position, thereby isolating the inner cavity of the cage 3 and the water outlet 11, and storing water in the trough body 100; when the user needs to drain, the cage 3 is placed in the drainage position, thereby connecting the inner cavity of the cage 3 and the water outlet 11, and draining the trough body 100; when the cage 3 is blocked by kitchen waste, since the side wall of the lining 2 is provided with a water hole 22, an anti-blocking flow channel 21 is formed between the lining 2 and the outer shell 1, the water in the trough body 100 enters the anti-blocking flow channel 21 through the water hole 22, and is then discharged through the water outlet 11, ensuring the normal drainage function of the drainage filter. Since the side wall of the lining 2 is provided with a drainage hole 23, the drainage hole 23 is located below the water hole 22, and the residue flowing through the water hole 22 can be easily flushed out of the drainage hole 23 by the water flow, thereby avoiding the accumulation and residue of kitchen waste in the anti-blocking flow channel 21. The drainage filter provided in this embodiment has a simple structure and low manufacturing cost, which is conducive to large-scale promotion and application. It solves the problem that the cage 3 is blocked by kitchen waste and cannot drain water. When dealing with the residue blockage, the user does not need to reach into the sewage to take out the residue accumulated in the cage 3 to achieve the drainage function. The manual cleaning operation is convenient and clean, which reduces the user's housework burden and anxiety about sanitary blind spots, and improves the user's usage experience.

[0041] Optionally, the water hole 22 is a circular hole, and the drainage hole 23 is an elongated hole. The water hole 22 can be located above the upper edge of the lifting cage 3. The circular design of the water hole 22 can reduce the difficulty of machining the water hole 22. The drainage hole 23 can be located below the upper edge of the lifting cage 3. The elongated design of the drainage hole 23 can facilitate flushing of debris that enters the anti-blocking flow channel 21 through the water hole 22.

[0042] To improve the effect of flushing out residue, the width of the elongated hole is optionally greater than the diameter of the circular hole. Residue entering the anti-clogging channel 21 through the circular hole is smaller than the diameter of the circular hole and smaller than the width of the elongated hole. Residue flowing through the circular hole is easily flushed out of the elongated hole by the water flow, preventing food residue from accumulating and remaining in the anti-clogging channel 21.

[0043] Optionally, the bottom of the liner 2 is provided with a drainage hole 24, and the cage 3 is provided with a blocking portion 31. When the cage 3 is in the water storage position, the blocking portion 31 can block the drainage hole 24. It is understood that the side wall of the cage 3 is provided with a filter hole 33. When the filter hole 33 is not blocked by kitchen waste and the cage 3 is in the drainage position, the water in the inner cavity of the cage 3 enters between the cage 3 and the liner 2 through the filter hole 33, and is then discharged through the drainage hole 24 of the liner 2 and the water outlet 11 of the outer shell 1. When the user needs to store water, the cage 3 can be placed in the water storage position by pressing. At this time, the blocking portion 31 of the cage 3 blocks the drainage hole 24, thereby isolating the inner cavity of the cage 3 and the water outlet 11, and the tank body 100 is filled with water.

[0044] To facilitate the secure installation of the outer shell 1 and the inner liner 2 on the tank body 100, the drain filter optionally further includes a locking screw 4, by which the outer shell 1 is locked to the inner liner 2, so that the tank body 100 is sandwiched between the outer shell 1 and the inner liner 2. The threaded connection of the locking screw 4 can adjust the degree of locking between the outer shell 1 and the inner liner 2, thereby adjusting the compressive force applied to the tank body 100, thereby facilitating a seal between the tank body 100, the outer shell 1, and the inner liner 2.

[0045] Optionally, the housing 1 is provided with a mounting portion 12, which is provided with a threaded hole and a relief hole 13. The threaded hole is threadedly engaged with the locking screw 4, and the relief hole 13 is connected to the water passage 22. The provision of the mounting portion 12 allows the locking screw 4 to be mounted on the central axis of the housing 1, ensuring uniform locking force between the housing 1 and the liner 2, and preventing damage to the housing 1 and liner 2 due to uneven force. Water in the inner cavity of the cage 3 enters between the cage 3 and the liner 2 through the filter holes 33, and is then discharged through the drainage holes 24 of the liner 2, the relief hole 13 of the mounting portion 12, and the water outlet 11 of the housing 1.

[0046] To facilitate lifting or pressing the lifting cage 3, the locking screw 4 is optionally provided with a guide hole 41, and the lifting cage 3 is provided with a guide rod 32 that slides with the guide hole 41. The guide rod 32 can slide with the guide hole 41 in the vertical direction, making it convenient for the user to perform lifting or pressing operations in the vertical direction.

[0047] Optionally, a lower sealing gasket 5 is provided between the outer shell 1 and the tank body 100, and an upper sealing gasket 6 is provided between the inner liner 2 and the tank body 100. Under the locking force of the locking screw 4, the lower sealing gasket 5 is sandwiched between the outer shell 1 and the tank body 100, thereby ensuring the sealing between the outer shell 1 and the tank body 100, and the upper sealing gasket 6 is sandwiched between the inner liner 2 and the tank body 100, thereby ensuring the sealing between the inner liner 2 and the tank body 100.

[0048] During water storage, water in the tank body 100 may flow out through the water hole 22 into the gap between the inner liner 2 and the outer shell 1. Optionally, the inner sidewall of the outer shell 1 is provided with a mounting groove 14, on which a sealing ring 7 is provided. The sealing ring 7 is sandwiched between the outer shell 1 and the inner liner 2, and is located below the water hole 22. The sealing ring 7 seals the gap between the inner liner 2 and the outer shell 1, preventing water in the tank body 100 from flowing out through the gap between the inner liner 2 and the outer shell 1 during water storage, thereby saving water resources and ensuring the normal water storage function.

[0049] This embodiment further provides a water tank, including a tank body 100 and the above-mentioned drainage filter, wherein the drainage filter is disposed at the bottom of the tank body 100 . When the user needs to store water, the cage 3 is placed in the water storage position, thereby isolating the inner cavity of the cage 3 and the water outlet 11, and storing water in the trough body 100; when the user needs to drain, the cage 3 is placed in the drainage position, thereby connecting the inner cavity of the cage 3 and the water outlet 11, and draining the trough body 100; when the cage 3 is blocked by kitchen waste, since the side wall of the lining 2 is provided with a water hole 22, an anti-blocking flow channel 21 is formed between the lining 2 and the outer shell 1, the water in the trough body 100 enters the anti-blocking flow channel 21 through the water hole 22, and is then discharged through the water outlet 11, ensuring the normal drainage function of the drainage filter. Since the side wall of the lining 2 is provided with a drainage hole 23, the drainage hole 23 is located below the water hole 22, and the residue flowing through the water hole 22 can be easily flushed out of the drainage hole 23 by the water flow, thereby avoiding the accumulation and residue of kitchen waste in the anti-blocking flow channel 21. The drainage filter provided in this embodiment has a simple structure and low manufacturing cost, which is conducive to large-scale promotion and application. It solves the problem that the cage 3 is blocked by kitchen waste and cannot drain water. When dealing with the residue blockage, the user does not need to reach into the sewage to take out the residue accumulated in the cage 3 to achieve the drainage function. The manual cleaning operation is convenient and clean, which reduces the user's housework burden and anxiety about sanitary blind spots, and improves the user's usage experience.
