[0019] like Figures 1-9 As shown, the present invention provides a water drain for a basin, which is arranged on the water drain pipe of the basin and partially located in the basin, comprising: a water stopper body 1, an upper shell 5, a spring assembly, and a filter assembly; The upper shell 5 is arranged at the drain outlet of the basin and has a receiving space for accommodating the filter assembly. The filter assembly is clearance-matched with the upper shell 5. The water stopper body 1 is arranged inside the filter assembly through a spring assembly and cooperates with the filter assembly to seal the gap between the upper shell 5 and the drain outlet. The filter assembly includes a filter outer frame 4 arranged inside the upper shell 5, and a sliding base support 9 slidably arranged on the filter outer frame 4. The size of the sliding base support 9 is the same as the opening size of the filter assembly. The bouncing assembly has an unlocking position and a locking position. When the bouncing assembly is in the unlocking position, the water stop plug body 1 is out of interference with the filter assembly, and the elastic force of the bouncing assembly drives the sliding base support 9 from the bottom of the filter assembly to the top of the filter assembly. In the above structure, a sliding base support 9 is provided inside the filter assembly and is slidably arranged with the filter outer frame 4 to realize the design of the dynamic sliding base support 9. Pulling up the water stop plug can link the sliding base support 9 to bring out the garbage in the filter, and then the cleaning process can be realized without disassembling the entire assembly, which effectively improves the cleaning efficiency. At the same time, the filter assembly is detachable as a whole, and garbage can be taken out with one hand, solving the cleaning pain points of the traditional structure.

[0020] In one possible implementation method, when the bouncing assembly is in the locking position, the water stop plug body 1 interferes with the filter screen assembly. The bouncing assembly includes a spring valve core 2. The locking position ensures that there is no gap between the water stop plug body 1 and the filter screen assembly to avoid water leakage.

[0021] In one possible implementation, the filter assembly further includes an upper cover 3; The inner wall of the filter frame 4 is provided with at least one slide groove 43 that passes through the inner wall of the filter frame 4. The sliding base 9 is provided with a plurality of sliding ribs 91 that cooperate with the slide groove 43. Each sliding rib 91 is provided with a slide groove 43 in a one-to-one correspondence. The filter frame 4 is also provided with a plurality of card slots 42. The circumference of the upper cover 3 is provided with a plurality of buckles 31, each of which is engaged with a card slot 42. The upper cover 3 is engaged with the filter frame 4 through the cooperation of the buckles 31 and the card slots 42, and when the spring When the jump assembly is in the unlocking position, the upper cover 3 is used to limit the maximum displacement distance of the sliding base 9 on the axis of the filter outer frame 4. A plurality of latches 92 are provided on the side of the sliding base 9 away from the upper cover 3. The latches 92 are engaged with the frame of the filter outer frame 4, wherein the latches 92 have two first guide surfaces 94 and second guide surfaces 95 with different inclination angles. The first guide surface 94 and the second guide surface 95 are arranged in an eight-shaped shape. Two guide surfaces are provided at the position where the frame of the filter outer frame 4 contacts the first guide surface 94 and the second guide surface 95. The angles of the two guide surfaces correspond to the first guide surface 94 and the second guide setting respectively. The upper cover 3 is mainly used to act as a baffle to prevent the sliding base 9 from being pulled out when sliding upward. The upper cover 3 is connected to the filter outer frame 4 through the cooperation of the buckle 31 and the slot 42 to achieve an inverted connection. The installation is convenient and quick. The specific installation process is: first install the sliding rib 91 of the sliding base 9 into the corresponding slide groove 43 of the filter outer frame 4, slide it downward and push it to the bottom until the latch 92 on the back of the sliding base 9 is in contact with the filter. The frame of the net outer frame 4 is snapped in, and then the buckle 31 of the upper cover 3 is snapped into the corresponding slot 42. It is worth noting that the present invention also provides a sealing ring 11 on the circumferential surface of the upper cover 3, which is mainly used to seal the gap between the upper cover 3 and the water stop plug body 1. At the same time, the bayonet 92 is provided with a first guide surface 94 and a second guide surface 95 in an eight-shaped shape, and corresponding guide surfaces are provided at the corresponding positions, thereby forming a double guide surface, which effectively reduces the assembly resistance and facilitates the spring valve core 2 to switch back and forth between the unlocking position and the locking position.

[0022] In one possible implementation, the filter outer frame 4 is further provided with a plurality of overflow holes 41, wherein the overflow holes 41 are spaced apart between the slide grooves 43, wherein each overflow hole 41 is provided with a filter, wherein there is a gap between the filter and the upper shell 5, and the overflow hole 41 is embedded with a filter to block hair, thereby preventing impurities such as hair from clogging the sewer pipe.

[0023] In one possible implementation, the lower shell 8 is further included, one end of which is threadedly connected to the upper shell 5, and the other end is provided with a water pipe. The water pipe at the lower end can be connected to a P-bend or S-bend, which is not specifically limited in the present invention.

[0024] In one possible implementation method, it also includes an upper table sealing gasket 6, which is annularly arranged on the outer side of the upper shell 5 for sealing the gap between the upper shell 5 and the water outlet, and also includes an under-table sealing gasket 7, which is annularly arranged on the outer side of the lower shell 8 for sealing the gap between the upper shell 5 and the lower shell 8. The upper table sealing gasket 6 and the under-table sealing gasket 7 can both be made of rubber material. The good sealing properties of rubber itself are used to seal the gap between the upper shell 5 and the water outlet, and the gap between the upper shell 5 and the lower shell 8, thereby effectively improving the sealing properties of the overall structure.

[0025] In one possible implementation method, the bottom of the sliding base 9 is also provided with a mounting hole 93 for installing a bouncing component, and the bouncing component is threadedly connected to the mounting hole 93. It is worth noting that in the present invention, the small end of the spring valve core 2 faces downward. After installation with the sliding base 9, a larger water flow area will be obtained, thereby making the drainage area larger. At the same time, the other end of the spring valve core 2 can also be threadedly connected to the water stop plug body 1. When it is necessary to clean the garbage in the filter screen, hold the water stop plug body 1 with one hand and pull it out. The water stop plug body 1 together with the spring valve core 2 and the sliding base 9 move upward, and the sliding base 9 will pull out the garbage so that it can be manually poured into the trash can. At this time, when the filter sliding base 9 slides to the top of the filter outer frame 4, it is convenient to clean the garbage and dirt on the sliding base 9. After cleaning the garbage, push the water stop plug body 1 downward until the pin 92 on the sliding base 9 is buckled into the filter outer frame 4 to complete the installation.

[0026] In one possible implementation, there are six sliding ribs 91, and the angle between every two adjacent sliding ribs 91 is the same as the angle between any two adjacent sliding ribs 91. The sliding base 9 is provided with multiple sliding ribs 91 and multiple latches 92, so that the sliding base 9 can be inverted and set inside the filter frame 4. When it is not sliding, the stability is effectively improved. When it is sliding, the multiple sliding ribs 91 effectively improve the sliding stability.
