[0019] In the fourth technical solution, a water inlet is provided on the side wall of the first groove so as to be connected to the valve core. The second seat body passes through the side wall of the basin body and is sleeved outside the first groove, the first fixing portion is fixed to the side wall of the first groove, the first abutting portion is also sealed with the second seat body, and a water inlet channel connecting the water inlet and the water inlet is formed between the second seat body, the side wall of the first groove and the first fixing member, so that the water inlet can be connected to the valve core, and the water inlet of the water inlet is controlled by the valve core.

[0020] In the fifth technical solution, the first seat body and the outer wall surface of the side wall of the basin body are sealed, and an overflow inlet connected to the overflow outlet is formed between the second seat body and the side wall of the basin body, and the overflow inlet is located below the water inlet, thereby realizing the overflow function of the overflow device. In addition, since the overflow inlet is formed between the second seat body and the side wall of the basin body, the arrangement is simpler than setting up an overflow inlet separately.

[0021] In the sixth technical solution, a linkage part, an operating part and a push-up part are additionally arranged. The linkage part is sleeved on the end of the valve stem extending out of the first groove opening and is fixed relative to it. The operating part is provided with a connecting part and an operating part. The connecting part is sleeved outside the linkage part. The operating part is suitable for being operated to rotate the operating part. The push-up part is fixed to the connecting part and penetrates through the connecting part to push against the linkage part, so that when the operating part rotates, it is suitable for driving the valve stem to rotate through friction force, thereby realizing control of the valve core.

[0022] In the seventh technical solution, by adding a workpiece, the workpiece is suitable for connecting to the second fixing member, so as to be suitable for being operated to install or remove the second fixing member, thereby facilitating the disassembly of the valve core.

[0043] The second seat body 3 is provided with a water inlet 28. The first seat body 2 and the second seat body 3 are provided with at least two limiting parts 29 (two in this embodiment, and more in other embodiments). The first seat body 2 and the second seat body 3 are suitable for being fixedly connected to each other through the limiting parts 29. The second seat body 3 is sleeved outside the first groove 24 and sealed against the outer wall of the first groove 24. The second seat body 3 and the first seat body 2 can be plugged in and fixedly connected to each other through the limiting parts 29. Specifically in this embodiment, Figure 6 As shown, two limiting portions 29 are provided on the second seat body 3, and both limiting portions 29 are plugged into the first seat body 2 as plug rods. For the method of achieving fixed connection by plugging, interference fit can be adopted, or it can be achieved by the first fixing member 4 described below. In some embodiments, the two limiting portions 29 can also be provided on the first seat body 2 and then plugged into the second seat body 3. In some embodiments, the second seat body 3 and the first seat body 2 can each be provided with a limiting portion 29 and then plugged into each other through the limiting portion 29. In some embodiments, the limiting portion 29 can also be used as a plug rod instead of a slot, and then a corresponding plug rod can be provided on other components to achieve plug-in. In addition, it should be noted that the second direction can be any direction perpendicular to the first direction 30, which needs to be determined according to the direction of the torque applied to the second seat body 3 and the first seat body 2.

[0044] The first fixing member 4 is provided with a first fixing portion 25 and a first abutting portion 26. The first fixing portion 25 is fixed to the side wall of the first groove 24 of the first seat body 2. The first abutting portion 26 is suitable for abutting the second seat body 3 along the first direction 30 to prevent the second seat body 3 from being disconnected from the first seat body 2. In this embodiment, the first fixing portion 25 is cylindrical and sleeved outside the first groove 24. The first abutting portion 26 is annular so as to abut the second seat body 3 sleeved outside the first groove 24. The first abutting portion 26 is also sealed with the second seat body 3. The water inlet 22 connected to the water inlet 21 and the water inlet 28 is formed between the second seat body 3, the side wall of the first groove 24 and the first fixing member 4. The overflow inlet 23 is located below the water inlet 22.

[0045] The valve core 6 is suitable for being installed in the first groove 24, and the second fixing member 5 is suitable for being fixed to the side wall of the first groove 24 by screw connection and abutting the valve core 6 along the first direction 30 so that the valve core 6 is fixed in the first groove 24, and the valve stem 7 of the valve core 6 passes through the second fixing member 5. In this embodiment, the valve core 6 adopts a valve core 6 (the valve plate is not shown in the figure) with two water inlets at the bottom and one water outlet, and the side can discharge water. When the side of the valve core 6 discharges water, it can be connected to the water outlet 21. In other embodiments, other types of valve cores 6 can also be used as needed.

[0046] The linkage member 8 is sleeved on the end of the valve stem 7 extending out of the opening of the first groove 24 and fixed by screws.

[0047] The operating member 9 is provided with a connecting portion 19 and an operating portion 20. The connecting portion 19 is sleeved outside the linkage member 8, and the operating portion 20 is suitable for being operated to rotate the operating member 9.

[0048] The abutting member 10 is fixedly connected to the connecting portion 19 and penetrates the connecting portion 19 to abut the linkage member 8 , so that when the operating member 9 rotates, it is suitable for driving the linkage member 8 to rotate through friction force and then driving the valve stem 7 to rotate.

[0049] The workpiece 11 is suitable for being connected to the second fixing member 5, and is suitable for being operated to install or remove the second fixing member 5, thereby realizing the installation or removal of the valve core 6. The workpiece 11 is also suitable for being sleeved outside the connecting portion 19. In this embodiment, the abutting member 10 can also penetrate the workpiece 11 sleeved outside the connecting portion 19, thereby penetrating the connecting portion 19 and then abutting the linkage member 8. The connection method between the workpiece 11 and the second fixing member 5 is a clamping connection realized by a clamping protrusion and a clamping groove.

[0050] The first water inlet pipe 31, the second water inlet pipe 32, and the water outlet pipe 33 are fixedly connected to the first seat body 2 by means of the pin 35, that is, the first water inlet pipe 31, the second water inlet pipe 32, and the water outlet pipe 33 all have hard connecting heads. After the connecting heads of the first water inlet pipe 31, the second water inlet pipe 32, and the water outlet pipe 33 are inserted into the first seat body 2, the pin 35 is inserted into the first seat body 2 to press against the connecting heads, so that the first water inlet pipe 31, the second water inlet pipe 32, and the water outlet pipe 33 can be limited in position, thereby preventing the first water inlet pipe 31, the second water inlet pipe 32, and the water outlet pipe 33 from being detached from the fixed connection, and this fixing method is relatively simple. In this embodiment, the first water inlet pipe 31 and the second water inlet pipe 32 correspond to the two water inlet holes on the bottom of the valve core 6, and the water outlet pipe 33 is suitable for corresponding to the water outlet hole on the bottom of the valve core 6. The water outlet 21 located on the side wall of the first groove 24 is also suitable for connecting to the water outlet hole on the side of the valve core 6 so that the water inlet 28 can connect to the valve core 6. The first water inlet pipe 31 and the second water inlet pipe 32 are used to connect cold water and hot water respectively, and the water outlet pipe 33 is used to discharge water, which can be connected to the shower 34.

[0051] The water discharge device can be installed on the basin body 1 (such as the basin body 1 of a bathtub) to start working. The installation relationship is as follows:

[0052] The valve housing 13 of the drain valve 12 is fixed to the bottom wall of the basin body 1, so that the water collection port 17 is connected to the inside of the basin body 1. The overflow device is suitable for being installed on the side wall 36 of the basin body, that is, the first seat body 2 is sealed and connected to the outer wall surface of the side wall 36 of the basin body, the overflow outlet 27 is located outside the basin body 1, the opening of the first groove 24 faces the side wall 36 of the basin body, and the water inlet 28 of the second seat body 3 is located inside the basin body 1. The second seat body 3 is passed through the side wall 36 of the basin body so that it is sleeved outside the first groove 24 and sealed with the outer wall of the first groove 24, and an overflow inlet 23 connected to the overflow outlet 27 is formed between the second seat body 3 and the side wall 36 of the basin body. The limiting portion 29 is suitable for penetrating the side wall 36 of the basin body along the first direction 30, and is also suitable for abutting the side wall 36 of the basin body along the second direction perpendicular to the first direction 30, that is, the two limiting portions 29 are used as insertion rods and inserted into the first seat body 2 after penetrating the side wall 36 of the basin body. The installation relationship among the first fixing member 4, the valve core 6, the linkage member 8, the operating member 9, the abutting member 10, the workpiece 11, the first water inlet pipe 31, the second water inlet pipe 32 and the water outlet pipe 33 is as described above.

[0053] The working principle of the overflow device in this embodiment is as follows:

[0054] like Figure 4As shown, since the overflow inlet 23 is located below the water inlet 22, and the first seat body 2 is sealed with the outer wall surface of the side wall 36 of the basin body, the overflow inlet 23 can be connected to the overflow outlet 27 and then to the overflow pipe 15, thereby realizing the overflow function without affecting the water inlet function of the water inlet 28. By operating the operating part 20 to rotate the valve stem 7 and then operate the valve core 6, the temperature of the water inlet 28 can be adjusted, or the water inlet 28 is stopped from inletting water into the basin body and the water flows to the outlet pipe 33.

[0055] like Figure 7 As shown, since the overflow device in this embodiment has a workpiece 11, the operating member 9 can be removed after the push member 10 is removed to take out the workpiece 11, and the workpiece 11 is connected to the second fixing member 5, so that the second fixing member 5 can be disassembled and assembled more easily through the workpiece 11, thereby making it easier to disassemble and assemble the valve core 6.

[0056] like Figure 6 As shown, since the two limiting portions 29 can penetrate the side wall 36 of the basin body along the first direction 30, and the second seat body 3 and the first seat body 2 are fixedly connected by the limiting portions 29, when the second fixing member 5 is rotated to disassemble and assemble the valve core 6 or when the rotating operating member 9 operates the valve core 6, the limiting portions 29 can press against the side wall 36 of the basin body along the second direction perpendicular to the first direction 30, thereby preventing the second seat body 3 and the first seat body 2 from being driven to rotate.

[0057] In this embodiment, since the first seat body 2 and the second seat body 3 are provided with at least two limiting parts 29, the limiting parts 29 are suitable for penetrating the side wall 36 of the basin body along the first direction 30, and are also suitable for abutting the side wall 36 of the basin body along the second direction perpendicular to the first direction 30. Therefore, when the first seat body 2 and the second seat body 3 are driven to generate a tendency to rotate, each limiting part 29 will counteract the tendency to rotate by abutting the side wall 36 of the basin body along the second direction, so that the first seat body 2 and the second seat body 3 cannot be driven to rotate. Therefore, when the valve core 6 is rotated and disassembled on the overflow device, it is not necessary to additionally fix the second seat body 3 and the first seat body 2, which is more convenient.

[0058] In this embodiment, the first seat body 2 and the second seat body 3 are plugged together through the limiting portion 29, which is convenient for installation. However, even if they are plugged together through interference fit, the second seat body 3 and the first seat body 2 may be separated from each other under the action of water pressure. Therefore, a first fixing member 4 is added, and the first fixing member 4 is provided with a first fixing portion 25 and a first abutting portion 26, so that the first fixing portion 25 is fixed to the first seat body 2, and the first abutting portion 26 abuts the second seat body 3 along the first direction 30, thereby preventing the second seat body 3 from being disconnected from the first seat body 2.

[0059] In this embodiment, by adding a second fixing member 5 and a valve core 6, the first seat body 2 is provided with a first groove 24 suitable for installing the valve core 6, and the second fixing member 5 is suitable for being fixed to the side wall of the first groove 24 and abutting the valve core 6 along the first direction 30 to fix the valve core 6 in the first groove 24, thereby realizing the installation of the valve core 6 on the overflow device. The valve stem 7 of the valve core 6 passes through the second fixing member 5, so as to facilitate the operation of the valve stem 7.

[0060] In this embodiment, a water inlet 21 is provided on the side wall of the first groove 24 so as to be connected to the valve core 6. The second seat body 3 passes through the side wall 36 of the basin body and is sleeved outside the first groove 24. The first fixing portion 25 is fixed to the side wall of the first groove 24. The first abutting portion 26 is also sealed with the second seat body 3. A water inlet 22 connecting the water inlet 21 and the water inlet 28 is formed between the second seat body 3, the side wall of the first groove 24 and the first fixing member 4, so that the water inlet 28 can be connected to the valve core 6, and the water inlet of the water inlet 28 is controlled by the valve core 6.

[0061] In this embodiment, the first seat body 2 is sealed with the outer wall surface of the side wall 36 of the basin body, and an overflow inlet 23 connected to the overflow outlet 27 is formed between the second seat body 3 and the side wall 36 of the basin body, and the overflow inlet 23 is located below the water inlet 22, thereby realizing the overflow function of the overflow device. In addition, since the overflow inlet 23 is formed between the second seat body 3 and the side wall 36 of the basin body, the arrangement is simpler than setting up the overflow inlet 23 separately.

[0062] In this embodiment, by adding a linkage member 8, an operating member 9 and a push member 10, the linkage member 8 is sleeved on the end of the valve stem 7 that extends out of the opening of the first groove 24 and is fixed relative to it, the operating member 9 is provided with a connecting portion 19 and an operating portion 20, the connecting portion 19 is sleeved outside the linkage member 8, the operating portion 20 is suitable for being operated to rotate the operating member 9, the push member 10 is fixedly connected to the connecting portion 19 and penetrates the connecting portion 19 to push against the linkage member 8, so that when the operating member 9 rotates, it is suitable for driving the valve stem 7 to rotate through friction force, thereby realizing control of the valve core 6.

[0063] In this embodiment, by adding a workpiece 11, the workpiece 11 is suitable for connecting to the second fixing member 5, so as to be suitable for being operated to install or remove the second fixing member 5, thereby facilitating the disassembly of the valve core 6. The workpiece 11 is also sleeved outside the connecting portion 19, so as to facilitate storage and prevent loss.

[0064] like Figure 8 As shown, this embodiment also provides a bathtub, which includes a basin body 1 , an overflow device fixedly connected to a side wall 36 of the basin body, a valve housing 13 fixedly connected to a bottom wall of the basin body 1 , and a water outlet pipe 33 connected to a shower head 34 .
