[0002] As people's quality of life continues to improve, bathtubs are becoming increasingly common in home bathroom facilities. To meet diverse usage needs, some bathtubs are equipped with massage chambers. This internal water system provides a water massage function, providing users with a more comfortable bathing experience.

[0003] In the existing bathtub drain design, it is usually necessary to set up a first drain port and a second drain port separately, wherein the first drain port is used to connect to the bathtub body to drain the bath water in the bathtub; the second drain port is used to connect to the massage chamber water channel inside the bathtub to drain the accumulated water in the massage chamber. However, this double drain port design has obvious defects. In the prior art, the drainage operations of the first drain port and the second drain port are not performed synchronously. When the user opens the first drain port to drain the bath water in the bathtub, the drainage of the massage chamber is not synchronized, which results in water still accumulating in the massage chamber after the bathtub body is drained. The accumulated water that remains for a long time is very likely to breed bacteria, mold and other microorganisms, which not only produces an unpleasant odor, but also may pose a potential threat to the user's health. At the same time, the accumulated water in the massage chamber will also increase the difficulty and frequency of daily cleaning and maintenance, reducing the user's experience.

[0037] See also Figure 1-Figure 7 , a bathtub drain, the bathtub drain includes a drain body 10, the drain body 10 is connected to a first water inlet 110, a second water inlet 120 and a drain outlet 130; the drain body 10 is provided with a first blocking module 20 for blocking the first water inlet 110; the drain body 10 is provided with a second blocking module 30 for blocking the second water inlet 120; a synchronous linkage module 40 is provided in the drain body 10; the synchronous linkage module 40 is used to link the first blocking module 20 and the second blocking module 30; when the first blocking module 20 moves from the open position to the sealing position, it synchronously drives the second blocking module 30 to move from the open position to the sealing position; when the first blocking module 20 moves from the sealing position to the open position, the second blocking module 30 synchronously moves from the sealing position to the open position. This embodiment effectively overcomes the problem of asynchronous drainage of dual-drain bathtub drains in the prior art by providing a synchronous linkage module to link the first and second blocking modules. When the user manipulates the first blocking module to change its position, the synchronous linkage module drives the second blocking module to move synchronously, achieving synchronized opening and closing of the first and second water inlets. This ensures that accumulated water in the bathtub body and massage chamber is drained simultaneously, preventing water from accumulating in the massage chamber.

[0038] See also Figures 2 to 5The synchronous linkage module 40 includes a constraint base 410, a track matching piece 440, a first elastic element 430 for providing an upward thrust to the first blocking module 20, and a synchronous driving piece 450. The first blocking module 20 is arranged to move up and down relative to the constraint base 410, and the constraint base 410 is provided with a track groove 420; the track matching piece 440 is connected to the first blocking module 20 and is moved along the track groove 420; the track groove 420 is provided with a first limiting groove 423 and a second limiting groove 424; when the track matching piece 440 is hooked in the first limiting groove 423, the first blocking module 20 remains in the sealing position; when the track matching piece 440 is hooked in the first limiting groove 423, the first blocking module 20 remains in the open position; the synchronous driving piece 450 moves synchronously with the first blocking module 20 and is used to drive the second blocking module 30 to switch positions.

[0039] To move the first sealing module 20 from the open position to the sealed position, it is necessary to press down on it, causing it to move downward. During this downward movement, the first elastic element 430 is compressed and accumulates force. During this process, the track engaging member 440 disengages from the second retaining groove and extends downward until it engages within the first retaining groove. Furthermore, as the first sealing module 20 moves, the driving member 450 moves synchronously with it and drives the second sealing module 30 from the open position to the sealed position.

[0040] See also Figure 2 The synchronous linkage module 40 also includes a moving part 400 that moves up and down relative to the constraint base 410, and the moving part 400 is connected to the first blocking module 20; one end of the track matching part 440 is connected to the moving part 400, and the other end is moved along the track groove 420.

[0041] See also Figure 2 The first blocking module 20 includes a sealing end cover 210 , which is connected to the moving part 400 , and the sealing end cover 210 is at least partially inserted into the first water inlet 110 .

[0042] Furthermore, a sealing ring 220 is provided at the portion of the sealing end cover 210 that is inserted into the first water inlet 110 , and the sealing ring 220 can improve the sealing performance.

[0043] See also Figure 2The first plugging module 20 further includes a threaded connector 230, which is threadedly connected to the movable member 400, and the movable member 400 is threadedly connected to the sealing end cap 210. The threaded connector 230 not only facilitates the connection, but also allows the height of the first plugging assembly 20 to be adjusted as needed, thereby avoiding errors that may cause a decrease in sealing performance.

[0044] See also Figure 5 The trajectory groove 420 is composed of a first travel groove 421 and a second travel groove 422 connected to each other; the first limiting groove 423 is arranged between the leading end of the first travel groove 421 and the trailing end of the second travel groove 422; and the second limiting groove 424 is arranged between the trailing end of the first travel groove 421 and the leading end of the second travel groove 422. When the first blocking module 20 moves from the open position to the sealed position, the trajectory fitting member 440 moves downward along the first travel groove 421 from the second limiting groove 424 and then enters the first limiting groove 423. Under the action of the first elastic element 430, the trajectory fitting member 440 can remain engaged in the first limiting groove 423. When the first blocking module 20 is pressed again, the trajectory fitting member 440 moves downward with the first blocking module 20 and enters the second travel groove 422. Then, under the action of the first elastic element 430, it moves upward to achieve movement from the sealed position to the open position until the trajectory fitting member 440 enters the second limiting groove 424.

[0045] In the present invention, the first elastic element 430 is a spring.

[0046] See also Figures 2 to 4 The second blocking module 30 includes a pipe fitting 310, a sealing member 320 and a second elastic element 340 which are interconnected with the second water inlet 120. The pipe fitting 310 is provided with a chamber 311 which is connected to the interior of the drain body 10, and the chamber 311 is provided with a sealing boss 312; the sealing member 320 is arranged to move relative to the chamber 311; the sealing boss 312 is connected to a follower 330 which extends to the interior of the drain body 10; the follower 330 is in contact with the synchronous driving member 450 for transmission.

[0047] In the present invention, the synchronous drive member 450 is composed of a first portion and a second portion. The outer diameter of the first portion is smaller than the outer diameter of the second portion, and the first portion is located above the second portion. When the second portion of the synchronous drive member 450 contacts the follower 330, the second portion pushes the synchronous drive member 450 to move the seal 320, causing the seal 320 to move away from the sealing boss 312, thereby connecting the chamber 311 with the interior of the drain body 10, allowing drainage. When the second portion of the synchronous drive member 450 contacts the follower 330, because the outer diameter of the first portion is smaller than the outer diameter of the second portion, there is space for the follower 330 and the seal 320 to return to their original position. Under the action of the second elastic element 340, the seal 320 returns to its original position and seals against the sealing boss 312, achieving a seal.

[0048] The second elastic element 340 is a spring, and its function is to push the sealing member 320 to fit and seal with the sealing boss 312 .

[0049] A limiting member 350 is provided at one end of the pipe 310 away from the drain body 10 , and the second elastic element 340 is provided between the limiting member 350 and the sealing member 320 .

[0050] See also Figure 6 and Figure 7 The drain body 10 is further provided with an overflow interface 140, which is communicated with the interior of the drain body 10. When in use, the overflow interface 140 is connected to the overflow pipe of the bathtub, and the overflow interface 140 is arranged to maintain a connected state so that the overflowed water flow can be quickly discharged into the interior of the drain body 10.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
