[0002] In the kitchen, the vegetable basin is an indispensable utensil, which is used to wash fruits, vegetables and other food materials, and can also be used to wash dishes. A drain is installed at the bottom of the vegetable basin, and the drain is connected to the sewer pipe. The waste water after washing is discharged to the sewer pipe through the drain.

[0003] The sewer is a tubular structure. In order to prevent the sewer pipe from being blocked, a filter basket is usually installed in the sewer. The filter basket is used to filter larger solid objects (such as fruit peels, food residues, etc.) in the wastewater to avoid blockage of the sewer.

[0004] However, in the prior art, the size adaptability between the outer diameter of the filter basket and the inner diameter of the drain piece is poor, and there is usually a large gap between the filter basket and the drain piece, which makes it impossible for the filter piece to be stably installed in the drain piece, and the filter basket is prone to shaking in the drain piece; and because the gap between the filter basket and the drain piece is too large, solid matter in the wastewater (such as fruit peels, food residues, etc.) is easy to fall into the gap between the filter basket and the drain piece, and food residues are easy to accumulate in the gap between the drain piece and the filter basket. The food residues are easy to get stuck in the gap and tend to stink over a long period of time. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] like Figures 1 to 6As shown, a dish basin drain includes a pipe fitting 1, an outer adapter 2, an inner adapter 3 and a filter 4. The pipe fitting 1 includes a first tube body 11 and a second tube body 12. A filter plate 13 is provided between the first tube body 11 and the second tube body 12. The second tube body 12 is vertically arranged on one side of the first tube body 11. The outer adapter 2 is installed in the first tube body 11, the inner adapter 3 is installed in the outer adapter 2, and the filter 4 is installed in the inner adapter 3. A first hollow area or filter hole is provided on the filter 4. The outer adapter 2 includes a first ring body 21 and a first flange structure 22 provided at the upper end of the first ring body 21. A rotation constraint groove 23 is provided on the outer side of the first ring body 21, and an entry groove 24 is provided on the lower side of the rotation constraint groove 23. A protrusion 14 is provided on the inner wall of the first tube body 11, and the protrusion 14 enters the rotation constraint groove 23 through the entry groove 24.

[0025] When the protrusion 14 is located in the rotation constraining groove 23 and the protrusion 14 moves from one end of the rotation constraining groove 23 to the other end of the rotation constraining groove 23 , the relative rotation angle between the outer adapter 2 and the first tube body 11 is 120° to 170°.

[0026] The outer diameter of the outer adapter 2 is matched with the inner diameter of the first tube body 11, the inner diameter of the inner adapter 3 is matched with the outer diameter of the filter element 4, and the inner diameter of the outer adapter 2 is matched with the outer diameter of the inner adapter 3. By installing the outer adapter 2 and the inner adapter 3 between the filter element 4 and the first tube body 11, the filter element 4 and the first tube body 11 can have good adaptability, and the filter element 4 can be stably installed in the first tube body 11, and the problem of large gap between the filter element 4 and the first tube body 11 and easy accumulation of food residues between the two is effectively solved. When it is necessary to replace the filter element 4 with a different outer diameter, it is only necessary to replace the corresponding inner adapter 3, so that the replaced filter element 4 can be matched with the first tube body 11. When installing the outer adapter 2 into the first tube body 11, it is only necessary to rotate the outer adapter 2 to a specific angle so that the protrusion 14 on the inner wall of the first tube body 11 is aligned with the entry groove 24, and then the protrusion 14 enters the rotation constraint groove 23 through the entry groove 24, and then rotate it appropriately to a certain angle to achieve the clamping connection between the filter element 4 and the first tube body 11, and the protrusion 14 can move within the length range of the rotation constraint groove 23, so that the outer adapter 2 can be rotated and adjusted within a certain angle range. The outer adapter cooperates with the first tube body through the protrusion and the rotation constraint groove. While the outer adapter is clamped, the outer adapter can be rotated at multiple angles in a specific space, so that the outer adapter can be installed at multiple angles. The external adapter is assembled through the protrusion and the rotation constraint groove. When assembling the external adapter, it is only necessary to insert the protrusion into the rotation constraint groove through the entry groove and rotate it at a small angle to clamp the external adapter. If the traditional threaded assembly method is adopted between the external adapter and the first tube body, the external adapter needs to be rotated a large number of times to install the external adapter in place. This assembly structure in the utility model greatly improves the convenience of assembly and disassembly of the external adapter.

[0027] A second hollow area is provided on the filter plate body 13. The first tube body 11, the second tube body 12 and the filter plate body 13 are integrally formed.

[0028] After the food residue in the wastewater is filtered once by the filter basket, the wastewater will pass through the filter plate 13 between the first tube body 11 and the second tube body 12 again, and the solid residue in the wastewater will be filtered again by the filter plate 13 to ensure that the sewer pipe is not blocked by the solid residue. The first tube body 11, the second tube body 12 and the filter plate 13 are integrally formed, making the overall structure and assembly process simpler.

[0029] The inner side of the first ring body 21 is provided with an internal thread 27, the inner adapter 3 includes a second ring body 31 and a second flange structure 32 arranged at the upper end of the second ring body 31, and the outer side of the second ring body 31 is provided with an external thread 33 adapted to the internal thread 27. The connection between the external adapter 2 and the internal adapter 3 is achieved through the cooperation between the external thread 33 and the internal thread 27, which facilitates the installation and replacement of the internal adapter 3.

[0030] Furthermore, a second sealing ring groove 26 is provided at the upper end of the first flange structure 22 , and a sealing ring is installed in the second sealing ring groove 26 ; when the inner adapter 3 is installed in the outer adapter 2 , the second flange structure 32 is sealed and matched with the sealing ring in the second sealing ring groove 26 .

[0031] The first ring body 21 is provided with a first sealing ring groove 25 for installing a sealing ring on its outer side. The first sealing ring groove 25 is located above the rotation restraining groove 23. A sealing ring is installed in the first sealing ring groove 25. When the outer adapter 2 is installed in the first tube body 11, the sealing ring installed in the first sealing ring groove 25 is sealed and matched with the inner wall of the first tube body 11.
