It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] Reference Figures 1 to 4 The embodiment of the utility model provides a spring-seal water drainer, comprising a water drain cup 1 which passes through from top to bottom and a plastic cup 2 which is sleeved outside the water drain cup 1, wherein a springer 4 and a filter basket 3 are installed in the water drain cup 1. The springer 4 is installed in the lower part of the inner cavity of the water drain cup 1. Specifically, a mounting seat which is fixedly connected to the inner wall is provided in the lower part of the inner cavity of the water drain body 1, and a mounting hole is provided in the center of the mounting seat, and the springer 4 passes through the mounting hole and is locked and fixed by a nut 6.

[0030] The lower water cup 1 has an upper opening and a lower opening that pass through from top to bottom. In this embodiment, the lower opening structure of the lower water cup is composed of a drainage hole surrounding the periphery of the bouncer. The drainage hole is arranged on the mounting seat.

The lower end surface of the support body 11 is provided with a connecting hole, and an inner nut 14 is fixedly provided in the connecting hole. The spring core 5 is provided with an external thread, and the spring core 5 is threadedly connected with the inner nut 14. The support body 11 moves with the spring core.

[0032] A lower installation groove 12 is circumferentially provided on the support body 11 and can be used to install the lower water sealing ring.

[0033] The filter basket 3 is supported on the support body 11 at the pressing end of the popper, and a top cover 7 is supported at the upper end of the filter basket 3. The top cover 7 is circumferentially provided with an upper water sealing ring 8 to form an upper water sealing cover. The lower water cup 1 has a space for the filter basket 3 to move up and down. The popper 4 is pressed by pressing the top cover 7, and the top cover 7 is pressed downward, so that the upper water sealing cover, the filter basket 3 and the bouncing core 5 move downward together, so that the upper water sealing cover blocks the upper end opening of the lower water cup 1 to achieve water sealing. At this time, the lower water device is in a water sealing state; the top cover 7 is pressed downward again, so that the upper water sealing cover, the filter basket 3 and the bouncing core 5 bounce upward together, and the upper water sealing cover is away from the upper end opening of the lower water cup 1, so that it is convenient to take out the filter basket 3 and the upper water sealing cover. The upper water sealing cover can be taken out to achieve drainage, which is easy to operate. The filter basket 3 filters the discharged water, filters out the solid debris in the water, and prevents the solid debris from flowing into the sewer pipe and causing the sewer pipe to be blocked.

[0034] There is no connection between the bouncer 4, the filter basket 3 and the top cover 7, so it is convenient to disassemble and assemble, and it is convenient to take out the filter basket 3 and the top cover 7 and clean them.

[0035] The lower end of the top cover 7 is provided with a support portion for supporting the upper end of the filter basket 3, the upper water sealing ring is located above the support portion, and the support portion is provided with a hollow structure 10 connected to the inner cavity of the filter basket 3. When the top cover 7 is supported on the filter basket 3, the bouncer 4 bounces up, and the upper water sealing ring 8 is separated from the upper end opening of the lower water cup 1, water can be discharged from the hollow structure 10 into the filter basket 3, thereby achieving drainage; since the hollow structure 10 has a small space and a small amount of water passing through, low-speed drainage is achieved; high-speed drainage is achieved by removing the upper water sealing cover; thus, low-speed drainage and high-speed drainage can be provided to users, meeting various usage requirements.

[0036] The hollow structure 10 can also provide a gripping position for fingers, making it convenient to grasp the upper water sealing cover.

[0037] Specifically, the support portion is composed of a plurality of L-shaped support legs 9 , and a hollow structure 10 is formed between adjacent support legs 9 .

[0038] An upper mounting groove for mounting an upper water sealing ring 8 is provided on the upper circumference of the top cover 7 , and the upper water sealing ring 8 is detachably mounted in the upper mounting groove, so that the upper water sealing ring 8 is conveniently replaced.

[0040] In another preferred embodiment, Figure 3 As shown, a lower water sealing ring 13 is installed in the lower installation groove 12, and the support body 11 and the lower water sealing ring 13 constitute a lower water sealing cover. The lower water sealing cover is located above the lower end opening of the lower water cup 1. When the bouncing core 5 is pressed down, the upper water sealing cover moves down to block the upper end opening of the lower water cup 1, and the lower water sealing cover moves down to block the lower end opening of the lower water cup 1, thereby realizing double water sealing; when the bouncing core 5 bounces upward, the upper water sealing cover moves up to be separated from the upper end opening of the lower water cup, and the lower water sealing cover moves up to be separated from the lower end opening of the lower water cup 1, thereby realizing low-speed drainage, and high-speed drainage is realized by removing the top cover 7.

[0041] A boss is provided on the support body 11, and the lower water sealing ring 13 is located below the boss. The filter basket 3 is supported on the boss. The boss allows a distance between the filter basket 3 and the lower water sealing ring 13 to prevent the lower water sealing cover from blocking the filter basket 3 from draining water.

[0042] Since the upper water sealing ring 8 and the lower water sealing ring 13 are both detachable, the top water sealing can be selected during use. Figure 2 As shown, the lower water sealing ring 13 is not installed, and the water is sealed by the upper water sealing ring 8 of the top cover 7; or the bottom water is sealed, such as Figure 4 As shown, the upper water sealing ring 8 is not installed, and water is sealed by the lower water sealing ring 13.
