[0002] The basin pop-up drain is a common drainage device in kitchen and bathroom sewers. Its function is to help drain water and prevent debris, food residues and other debris from entering the pipes, avoid clogging the pipes, ensure the smooth flow of the pipes, extend the service life of the pipes, and also facilitate cleaning and maintenance.
[0003] A spring drainer is usually composed of a bouncing core, an upper sealing part, a filter screen or a deodorizing plug. When the bouncing drainer is placed on the drain of the basin, the filter screen and the bouncing core are placed in the sewer pipe. As the sewage is discharged into the sewer pipe through the drain outlet, the debris mixed in the sewage is filtered in the filter screen. In order to enable the movable part to be able to retract and move, there is a gap between the fixed part and the movable part on the bouncing core. The upper end of the movable part is connected to the upper sealing part, and the fixed part is connected to the lower end of the movable part, so that the gap is set upward. Secondly, a clearance hole for connecting the spring assembly and the connecting head is also provided at the bottom of the spring core. This will cause small debris to easily enter the gap and the clearance hole into the inside of the spring core along the water flow, thereby causing the spring core to retract and expand normally, affecting the normal use of the drainer and shortening the service life of the spring drainer. Therefore, it is necessary to further optimize the existing bouncing drainer. Summary of the invention

[0021] 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 without creative work are within the scope of protection of the utility model.
[0022] Example 1: Figure 1-6 As shown, an improved bouncing drain assembly includes an upper sealing part 1 for sealing a basin drain outlet and a bouncing core 2, wherein the upper sealing part 1 is mounted on the upper end of the bouncing core 2, and the bouncing core 2 includes a fixed part 21 with a connector 25 at the end thereof and a movable part 22, wherein one end of the fixed part 21 is connected to the upper sealing part 1, and the movable part 22 is telescopically mounted on the other end of the fixed part 21, wherein the outer diameter of the fixed part 21 is greater than the outer diameter of the movable part 22, and an accommodating cavity is provided at the bottom of the upper sealing part 1 The connecting head 25 on the end of the fixed part 21 is placed in the accommodating cavity 13. Since the upper end of the movable part is assembled in the fixed part, there is a gap between the movable part and the fixed part. When the outer diameter of the fixed part is larger than the outer diameter of the movable part, the gap is set downward, which can reduce the debris in the sewage from directly passing through the gap into the spring core along the water flow during the drainage process of the basin. The air-avoiding hole is placed in the accommodating cavity of the connecting part, which reduces the debris from entering the spring core through the air-avoiding hole, which is beneficial to maintain the normal use cycle of the bouncing drain.
[0023] Among them, a connecting part 11 is arranged on the bottom surface of the upper sealing part 1, the accommodating cavity 13 is arranged inside the connecting part 11, a through hole 12 is arranged at the bottom of the connecting part 11, and the connecting head 25 of the fixing part 21 passes through the through hole 12 and is placed in the accommodating cavity 13.
[0024] The interior of the fixed portion 21 is hollow to form a telescopic space, the upper side of the movable portion 22 is assembled in the telescopic space of the fixed portion 21, and there is a gap between the inner wall of the fixed portion 21 and the outer wall of the movable portion 22. The opening of the gap 27 is arranged opposite to the connecting portion 11, and the opening of the gap faces downward, so that when the sewage rushes downward, the sewage will not enter the inside of the bouncing core directly along the gap with debris, but the debris in the sewage will accumulate on the filter net along the outer wall of the bouncing core, ensuring that the spring in the bouncing core is not affected by the debris and can be normally expanded and contracted.
[0025] Among them, the fixing part 21 is located on one side of the connecting head 25 and is provided with an air avoidance hole 23 for connecting the spring assembly to the connecting head 25. When the upper end of the fixing part 21 is connected to the connecting part 11, the air avoidance hole 23 is placed in the accommodating cavity 13 of the connecting part 11. Since the air avoidance hole is connected to the interior of the bouncing core, once debris enters the inside of the bouncing core from the air avoidance hole and accumulates in the spring core, it is easy for the spring in the bouncing core to be unable to expand and contract normally. Placing the air avoidance hole inside the connecting part can reduce the direct contact between the air avoidance hole and sewage, thereby reducing the situation where debris enters the inside of the bouncing core and maintaining the normal use cycle of the drainer.
[0026] Among them, a blocking part 24 is arranged on the upper side of the fixing part 21, and the outer diameter of the blocking part 24 is larger than the inner diameter of the through hole 12 on the connecting part 11. The blocking part 24 abuts against the bottom surface of the connecting part 11. The blocking part can prevent small debris from entering the interior of the connecting part through the through hole, thereby reducing the situation where debris enters the bouncing core and ensuring that the drain can be used normally.
[0027] The blocking portion is extended outward from the outer wall of the fixing portion, and the shape of the upper end surface of the blocking portion matches the shape of the bottom surface of the connecting portion, so that the blocking portion can abut against the bottom surface of the connecting portion.
[0028] The bouncing core 2 and the connecting portion 11 are connected by threaded connection or mutual adhesion, which reduces the entry of small debris into the connecting portion through the through hole and allows the debris to enter the bouncing core through the air-avoiding hole.
[0029] Among them, a fastening connection part which can be used to connect with the filter element is provided on the side of the movable part 22 opposite to the fixed part 21, and the outer wall of the fastening connection part is provided with an external thread which can cooperate with the thread on the filter element, so that the filter element can be detachably assembled on the water supply and drainage device, which is convenient for disassembly and cleaning.
[0030] Wherein, the bouncing core is made of metal material.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
