Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, and in particular to a washbasin assembly. Background Technology

[0002] A washbasin is an essential piece of sanitary ware in a bathroom, used to collect water after using the toilet or for daily washing.

[0003] The commonly used basin drainage structure on the market today includes a drain pipe and an overflow pipe. The overflow pipe controls the opening and closing of the drain pipe via a button on the countertop, thereby controlling the overall water storage or waterproofing of the drain. The existing control button is designed to be pressed vertically, which adds an area on the countertop that cannot be used for placing items, reducing the usable countertop area. Placing the button on the side of the basin can solve the problem of occupying countertop space, but the vertical pressing method is not convenient for placing the button on the side of the basin, and the two problems cannot be reconciled well. Summary of the Invention

[0004] The main objective of this invention is to provide a washbasin assembly that enables the button and drain assembly to be driven by rotation and pressing, facilitating the placement of the button on the side of the washbasin and reducing the surface area occupied on the countertop.

[0005] To achieve the above objectives, the present invention provides a washbasin assembly, the washbasin assembly comprising:

[0006] The basin body has a water-holding trough, and the wall of the water-holding trough has a drain hole.

[0007] A water storage tank, which forms a water storage space and has a drain outlet at the bottom of the water storage space, the drain outlet being connected to a drainage hole; a transmission assembly, which includes a connecting rod and a pressing member, the two ends of the connecting rod being rotatably connected to the side wall of the water storage tank, and the pressing member being inserted through the connecting rod;

[0008] A drainage assembly, movably disposed within the water storage space, with the pressing element positioned above the drainage assembly; and

[0009] A button is located on one side of the pressing member and drives the pressing member to rotate so as to press against the drain assembly and block the drain outlet, or to detach from the drain assembly and open the drain outlet.

[0010] Optionally, the basin body includes a main body and a countertop. The main body forms the water-holding trough. The countertop surrounds the periphery of the water-holding trough. The water storage tank is connected to the countertop. The side wall of the water-holding trough near the water storage tank has an installation groove. The installation groove communicates with the water storage space. The button is movably disposed in the installation groove.

[0011] The basin assembly also includes a top cover assembly, which includes a base and a top cover. The base is installed in the mounting groove, and the top cover is closed on the base. The base and the top cover together form a receiving cavity. The two ends of the connecting rod are rotatably connected to the cavity wall of the receiving cavity. The button is movable through the receiving cavity and drives the pressing member to rotate laterally.

[0012] Optionally, the pressing component includes a pressing part and a rotating part connected together. One end of the pressing part and the rotating part is sleeved on the connecting rod. The pressing part is located on the side of the connecting rod facing the drain assembly, and the rotating part is located on the side of the connecting rod facing the button.

[0013] Optionally, the pressing part and the rotating part are located on opposite sides of the connecting rod, and both the pressing part and the rotating part are arranged in a clockwise direction. The ends of the pressing part and the rotating part that are opposite to each other abut against the drain assembly and the button, respectively.

[0014] Optionally, the transmission assembly further includes two bearing seats, which are respectively connected to the two ends of the connecting rod. Limiting grooves are respectively formed on the opposite sides of the base, and the bearing seats are installed in the limiting grooves.

[0015] Optionally, the shaft seat has a fastening groove on the side opposite to the button, and the upper cover has a fastening piece on the side away from the button in a horizontal direction. The shaft seat is installed on the upper cover by engaging with the fastening piece through the fastening groove.

[0016] Optionally, the limiting groove is provided on the side of the base near the button, and the base is provided with a sliding groove extending along the limiting groove toward the side away from the button. The depth of the sliding groove is less than the depth of the limiting groove. The upper cover is installed on the base, and the shaft seat is provided in the limiting groove. The upper cover moves toward the direction away from the button, and the shaft seat disengages from the fastening piece and is fixed in the limiting groove.

[0017] Optionally, a limiting block is provided on the side of the top cover away from the button. The limiting block is positioned opposite the pressing member. When the top cover is installed on the base, the limiting block abuts against and limits the pressing member to restrict the rotatable angle of the pressing member.

[0018] Optionally, the basin assembly further includes a drain pipe and a mounting nut, the drain pipe being inserted through the drain outlet, and the mounting nut being located outside the water storage tank and threadedly connected to the drain pipe.

[0019] Optionally, the drainage assembly includes an overflow pipe, a spring-loaded core, and a basket. The overflow pipe is located above the drain pipe, and the basket is located inside the drain pipe. The basket has a movable groove on the side facing the overflow pipe. One end of the spring-loaded core is elastically connected to the overflow pipe, and the other end can be movably inserted through the movable groove. The transmission assembly drives the overflow pipe to open or block the drain pipe.

[0020] The technical solution of this invention uses a transmission component located between the drain assembly and the button. The transmission component includes a connecting rod and a pressing element. The connecting rod is rotatably connected to the side wall of the water storage tank mounting groove. The pressing element passes through the connecting rod and is positioned above the drain assembly. The button is located on one side of the pressing element. Pressing the button drives the pressing element to rotate, giving it a force that rotates and presses against the drain assembly, causing it to move downwards, thus achieving a water storage state where the overflow pipe blocks the drain outlet. Pressing the button again disengages the pressing element, causing it to return to its original position due to the rebound force of the overflow pipe, and the drain assembly moves upwards, achieving a water discharge state where the overflow pipe is released from the drain outlet. This transmission component's rotation and pressure against the drain assembly allows the button to drive the transmission component to rotate and press the drain assembly, avoiding the problem of occupying surface area on the basin, improving aesthetics, and preventing water accumulation at the button location.

[0040] This invention proposes a washbasin assembly 1.

[0041] In embodiments of the present invention, such as Figures 1 to 6 As shown, the basin assembly 1 includes a basin body 20, a water storage tank 10, a transmission assembly 30, a drain assembly 40, and a button 50. The basin body 10 has a water-holding trough 211, and the wall of the water-holding trough 211 has a drain hole 2111. The water storage tank 10 forms a water storage space, and a drain outlet 11 is provided at the bottom of the water storage space. The drain outlet 11 is connected to the drain hole 2111. The transmission assembly 30 includes a connecting rod 31 and a pressing member 33. The two ends of the connecting rod 31 are rotatably connected to the side wall of the water storage tank 10, and the pressing member 33 passes through the connecting rod 31. The drain assembly 40 is movably disposed in the water storage space, and the pressing member 33 is disposed above the drain assembly 40. The button 50 is disposed on one side of the pressing member 33 and drives the pressing member 33 to rotate, so as to press the drain assembly 40 and block the drain outlet 11, or to detach from the drain assembly 40 and open the drain outlet 11.

[0042] The basin assembly 1 includes a water storage tank 10 and a basin body 20. The basin body 20 and the water storage tank 10 are connected through a drain hole 2111, so the water level of the basin is the same as the water level of the water storage tank 10. When the water storage tank 10 is in a water-filled state, the water in the water storage tank 10 cannot be discharged from the drain outlet 11. The water is stored in the water storage tank 10, causing the water level to rise, and the water level in the basin also rises simultaneously, achieving the purpose of water storage. When the water storage tank 10 is in a water-discharging state, the water in the water storage tank 10 is discharged from the drain outlet 11, causing the water level to fall, and the water level in the basin also falls simultaneously. Therefore, the water storage tank 10 is designed to allow for water storage and discharge from the rear of the basin.

[0043] The basin assembly 1 includes a drain assembly 40, a transmission assembly 30, and a button 50. One end of the drain assembly 40 faces the drain outlet 11, and the other end faces the transmission assembly 30. The transmission assembly 30 includes a connecting rod 31 and a pressing member 33. The two ends of the connecting rod 31 are rotatably connected to the side wall of the water storage tank 10. The pressing member 33 passes through the connecting rod 31. The connecting rod 31 can rotate by rotating the two ends connected to the side wall of the water storage tank 10, thereby driving the entire connecting rod 31 to rotate, and finally driving the pressing member 33 to rotate. The pressing member 33 can rotate downward and press against the drain assembly 40 to fill water, and rotate upward and disengage from the drain assembly 40 to release water. When the pressing member 33 rotates downward, it abuts against the top of the overflow pipe 41 and pushes the overflow pipe 41 downward. The overflow pipe 41 moves downward and abuts against and blocks the drain outlet 11, thus sealing the channel between the water and the drain outlet 11. Water cannot flow out of the drain outlet 11 from the gap between the overflow pipe 41 and the drain outlet 11, achieving the state of water storage. When the pressing member 33 rotates upward, it disengages from the top of the overflow pipe 41, the overflow pipe 41 returns to its original position, moves upward and separates from the drain outlet 11, opening the channel between the water and the drain outlet 11. Water can flow out from the gap between the overflow pipe 41 and the drain outlet 11, achieving the state of water discharge.

[0044] The button 50 is designed to control the drain assembly 40 to squeeze or disengage from the drain outlet 11, thereby enabling the water tank 10 to switch between water storage and discharge. The button 50 can be positioned horizontally or vertically, meaning it can be placed on the countertop or on the side of the basin. When the button 50 is pressed, it abuts against the pressing member 33 and applies a downward rotating force, causing the overflow pipe 41 to move downwards and block the drain outlet 11. When the button 50 is pressed again, it moves in the direction of disengaging from the pressing member 33, disengaging from the pressing member 33. The pressing member 33, subjected to the rebound force of the overflow pipe 41, returns to its original position, and the overflow pipe 41 moves upwards to open the drain outlet 11.

[0045] The technical solution of this invention involves a transmission assembly 30 located between the drain assembly 40 and the button 50. The transmission assembly 30 includes a connecting rod 31 and a pressing member 33. The connecting rod 31 is rotatably connected to the side wall of the water storage tank 10. The pressing member 33 passes through the connecting rod 31 and is positioned above the drain assembly 40. The button 50 is located on one side of the pressing member 33. Pressing the button 50 drives the pressing member 33 to rotate, giving it a force that rotates and presses against the drain assembly 40, causing it to move downwards. This achieves water storage by sealing the drain outlet 11 with the overflow pipe 41. The button 50 is pressed again to disengage it from the pressing member 33, causing the pressing member 33 to return to its original position due to the rebound force of the overflow pipe 41. The drain assembly 40 moves upward, realizing the state of the overflow pipe 41 disengaging from the drain outlet 11. By rotating the transmission component 30 to press the drain assembly 40, the button 50 can drive the transmission component 30 to rotate and press the drain assembly 40, avoiding the problem of occupying the surface area of ​​the basin due to its placement on the surface of the basin, improving the aesthetics, and avoiding the problem of water accumulation at the button.

[0046] In one embodiment of the present invention, such as Figures 2 to 5 , Figures 8 to 13 As shown, the basin body includes a main body and a countertop. The main body forms the water-holding trough. The countertop surrounds the periphery of the water-holding trough. The water storage tank is connected to the countertop. The side wall of the water-holding trough near the water storage tank has an installation groove. The installation groove communicates with the water storage space. The button is movably disposed in the installation groove.

[0047] A mounting groove 2113 is provided on the side wall of the water tank 211 near the water reservoir 10. The button 40 passes through the mounting groove 2113. The mounting groove 2113 connects the water reservoir 10 and the basin body 20. The button 40 can move within the mounting groove 2113, so the user can press the button 40 through the opening 13 of the mounting groove 2113 located on the basin body 20. One end of the button 40 facing the basin body 20 can be pressed by the user, and the other end can be used to press the drain assembly 30 laterally. The mounting groove 2113 is provided on the side wall of the basin body 20 near the water reservoir 10. The button 40 is located in the mounting groove 2113, so the button 40 is located on the side wall of the main body 21, which avoids the button 40 protruding from the upper surface of the countertop 23, so that the surface of the countertop 23 has sufficient storage space, and avoids the problem of the button 40 sinking into the surface of the countertop 23 after being pressed, thus preventing water accumulation.

[0048] The basin assembly 1 also includes a top cover assembly 60, which includes a base 61 and a top cover 63. The base 61 is installed in the mounting groove 2113, and the top cover 63 covers the base 61. The base 61 and the top cover 63 together form a receiving cavity. The two ends of the connecting rod 31 are rotatably connected to the cavity wall of the receiving cavity. The button 50 is movable inside the receiving cavity and drives the pressing member 33 to rotate laterally.

[0049] The top cover assembly 60 includes a base 61 and a top cover 63. The base 61 is installed in the mounting groove 2113 with an interference fit, and can be reinforced and installed using screws, nuts, or other connecting parts. The top cover 63 is fitted onto the base 61, and the connection between the top cover 63 and the base 61 is detachable, such as by snap-fit ​​or threaded connection. The top cover 63 and the base 61 together form a receiving cavity, in which the transmission assembly 30 and the button 50 are both located. The two ends of the connecting rod 31 are rotatably connected to the cavity wall. Essentially, the two ends of the connecting rod 31 are connected to the edge of the top cover 63, thus fixing the position of the connecting rod 31. Furthermore, the connecting rod 31 is connected to the top cover 63 of the top cover assembly 60 and can be detachably installed on the base 61 along with the top cover 63, enabling the transmission assembly 30 to be detachable for maintenance and replacement.

[0050] Furthermore, the base 61 is provided with an anti-disengagement buckle, and the upper cover 63 is provided with a fixing buckle on the side facing the base 61. When the upper cover 63 and the base 61 are combined, the fixing buckle on the upper cover 63 and the anti-disengagement buckle on the base 61 are engaged to achieve the fixed combination and installation of the two. This installation method has high efficiency in combination and separation, and can complete the installation without additional tools. It has high installation efficiency and simple structure.

[0051] Furthermore, such as Figure 10 As shown, a button mounting groove 635 is also provided on the side of the upper cover 63 facing the base 61. The button mounting groove 635 is open at both ends. One end of the button mounting groove 635 faces the pressing member 33, and the other end faces the outside of the upper cover 63. When installing the button 50, the button 50 needs to be inserted from the opening at the end facing the pressing member 33 to the other end. In addition, a clearance groove is provided at the bottom of the button mounting groove 635. The button 50 is divided into two parts. One part is the pressing part 331, which passes through the button mounting groove 635. The other part is the fixing part, which is engaged with the outside of the button mounting groove 635 through the clearance groove. The clearance groove can limit and guide the button 50. The extension direction of the clearance groove is the same as the extension direction of the button mounting groove 635, ensuring that the button 50 moves in the direction facing the pressing member 33 when it is in the clearance groove. Furthermore, a hook is provided at one end of the clearance groove near the pressing member 33. The hook is located at the end of the clearance groove and can be used to limit the movement of the button 50, preventing the button 50 from sliding out of the button mounting groove 635 when pressed.

[0052] In one embodiment of the present invention, such as Figures 8 to 13 As shown, the pressing part 33 includes a pressing part 331 and a rotating part 333 connected together. One end of the pressing part 331 and the rotating part 333 is sleeved on the connecting rod 31. The pressing part 331 is located on the side of the connecting rod 31 facing the drain assembly 40, and the rotating part 333 is located on the side of the connecting rod 31 facing the button 50.

[0053] like Figure 12 As shown, the pressing member 33 includes a pressing part 331 and a rotating part 333 connected to each other. In one embodiment of the present invention, the pressing part 331 is a spiral circular block and the rotating part 333 is a circular rod. Since the pressing part 331, the rotating part 333 and the connecting rod 31 are all fixedly connected, the rotating part 333 is used to press the button 50 against the connecting rod 31 and transmit the force to the connecting rod 31. The pressing part 331 is used to absorb the rotational force of the connecting rod 31 and realize rotation. Finally, the pressing part 331 rotates and realizes the transmission of force to the drain assembly 40, thereby realizing the pressing of the drain assembly 40.

[0054] Furthermore, the outer contour of the pressing part 331 is an involute. The outer contour of the involute has the characteristic that the perpendicular line of the tangent at any point on the line is equidistant from the center of the circle. Therefore, during the transmission process, the contact point between the pressing part 331 and the drain assembly 40 (i.e., the contact position with the drain assembly 40) remains unchanged, and the pressing part 331 is not eccentric, thus ensuring the pressing effect of the transmission assembly 30 on the drain assembly 40.

[0055] In one embodiment of the present invention, such as Figures 8 to 13 As shown, the pressing part 331 and the rotating part 333 are located on opposite sides of the connecting rod 31. Both the pressing part 331 and the rotating part 333 are arranged in a clockwise direction. The ends of the pressing part 331 and the rotating part 333 that are opposite to each other abut against the drain assembly 40 and the button 50, respectively.

[0056] The pressing part 331 and the rotating part 333 are located on opposite sides of the connecting rod 31, maintaining the relative movement position of the pressing part 331 and the rotating part 333. Both the pressing part 331 and the rotating part 333 are bent in a clockwise direction, which facilitates the setting of the pressing part 331 and the rotating part 333 when installing the transmission assembly 30, so that their rotation angle and rotation position are the same, ensuring the transmission effect of the transmission assembly 30.

[0057] In one embodiment of the present invention, such as Figures 8 to 13 As shown, the transmission assembly 30 also includes two bearing seats 35, which are respectively connected to the two ends of the connecting rod 31. Limiting grooves 611 are respectively opened on the opposite sides of the base 61, and the bearing seats 35 are installed in the limiting grooves 611.

[0058] The transmission assembly 30 also includes two bearing seats 35, which are respectively connected to the two ends of the connecting rod 31. Each bearing seat 35 has a through hole 353, through which both ends of the connecting rod 31 pass and can rotate. Since the pressing member 33 is sleeved on the connecting rod 31, the pressing member 33 can rotate with the connecting rod 31. Limiting grooves 611 are provided on opposite sides of the base 61, and the bearing seats 35 are installed in the limiting grooves 611 so that the connecting rod 31 can rotate above the drain assembly 40.

[0059] Furthermore, a limit buckle is provided on the connecting rod 31, and a limit hole is provided on the through hole 353. When the connecting rod 31 passes through the through hole 353, the limit buckle needs to be passed through the limit hole in order to allow the connecting rod 31 to pass through the through hole 353 at the position where the limit buckle is provided. After passing through the limit hole, the connecting rod 31 is rotated. The limit buckle on the connecting rod 31 can only abut against the sealed surface on the bearing seat 35. This setting can prevent the connecting rod 31 from falling off the bearing seat 35 during the movement, thus maintaining the movement position and rotation effect of the connecting rod 31.

[0060] In one embodiment of the present invention, such as Figures 8 to 13 As shown, a fastening groove 351 is provided on the side of the shaft seat 35 away from the button 50, and a fastening piece 631 is provided on the side of the upper cover 63 away from the button 50 in the horizontal direction. The shaft seat 35 is installed on the upper cover 63 by engaging with the fastening piece 631 through the fastening groove 351.

[0061] like Figure 11 As shown, a fastening groove 351 is provided on the side of the bearing seat 35 away from the button 50, and a fastening piece 631 is provided horizontally on the side of the upper cover 63 away from the button 50. The upper cover 63 is installed in front of the base 61, and the transmission assembly 30 is installed on the upper cover 63. The bearing seat 35 is engaged with the fastening piece 631 through the fastening groove 351, so that the bearing seat 35 is fixed to the upper cover 63. Since the connecting rod 31 and the pressing member 33 are connected to the bearing seat 35, the entire transmission assembly 30 is installed on the upper cover 63. This arrangement ensures that the transmission assembly 30 can be simultaneously installed from the upper cover 63 onto the base 61 or simultaneously removed from the base 61 after the upper cover 63 is installed on or removed from the base 61, maintaining the synchronous installation and removal of the upper cover 63 and the transmission assembly 30.

[0062] In one embodiment of the present invention, such as Figures 2 to 5 , Figures 8 to 13As shown, the limiting groove 611 is located on the side of the base 61 near the button 50. The base 61 extends along the limiting groove 611 toward the side away from the button 50 and has a sliding groove 613. The depth of the sliding groove 613 is less than the depth of the limiting groove 611. The upper cover 63 is installed on the base 61. The shaft seat 35 is located in the limiting groove 611. The upper cover 63 moves away from the button 50, and the shaft seat 35 disengages from the fastening piece 631 and is fixed in the limiting groove 611.

[0063] like Figure 5 As shown, a limiting groove 611 is located on the side of the base 61 near the button 50. A sliding groove 613 extends from the limiting groove 611 towards the side away from the button 50. The depth of the sliding groove 613 is less than the depth of the limiting groove 611. When the upper cover 63 is installed on the base 61, the bottom of the bearing seat 35 is installed into the limiting groove 611. The fastening piece 631 of the upper cover 63 is tightly attached to the sliding groove 613. Pushing the upper cover 63 in the direction away from the button 50 fixes the bearing seat 35 within the limiting groove 611. Therefore, the connecting rod 31 and the pressing member 33 are synchronously fixed to the same horizontal position as the bearing seat 35, i.e., the middle of the base 61. The fastening groove 351 of the bearing seat 35 separates from the fastening piece 631 of the upper cover 63. The upper cover 63 then moves along the extension direction of the sliding groove 613 until the fixing buckle on the upper cover 63 engages with the anti-disengagement buckle on the base 61, thus achieving a fixed connection and installation. After being fixed, the bearing seat 35, connecting rod 31 and pressing member 33 are located in the middle of the base 61, the upper cover 63 completely covers the top of the base 61, and one end of the button 50 is set to abut against the pressing member 33.

[0064] When the upper cover 63 is removed from the base 61, the upper cover 63 is moved in the opposite direction, and the fixing buckle of the upper cover 63 is disengaged from the anti-disengagement opening on the base 61. The fastening piece 631 of the upper cover 63 moves toward the fastening groove 351 of the shaft seat 35 until the fastening piece 631 is engaged in the fastening groove 351. Then the shaft seat 35 and the upper cover 63 are combined. That is, the shaft seat 35, the connecting rod 31 and the pressing piece 33 are all combined with and fixed to the upper cover 63. The upper cover 63 and the base 61 are in a detachable state. The upper cover 63, the transmission assembly 30 and the base 61 can be separated by removing the upper cover 63 from the base 61.

[0065] In one embodiment of the present invention, such as Figures 8 to 13 As shown, a limiting block 633 is provided on the side of the upper cover 63 away from the button 50. The limiting block 633 is positioned directly opposite the pressing member 33. When the upper cover 63 is installed on the base 61, the limiting block 633 abuts against and limits the pressing member 33 to restrict the rotatable angle of the pressing member 33.

[0066] A limiting block 633 is provided on the side of the upper cover 63 away from the button 50, and the limiting block 633 is positioned directly opposite the pressing member 33. The setting of the limiting block 633 restricts the pressing member 33 from being squeezed and damaged due to excessive rotation angle caused by inertia during the installation of the upper cover 63 and the base 61, thus limiting the rotation angle of the pressing member 33. On the other hand, the limiting block 633 extends vertically. When the upper cover 63 is removed from the base 61, it needs to be moved in the opposite direction. Since the pressing member 33 is not fixed to rotate, it is easy for the pressing member 33 to rotate downward due to inertia during the movement. This could cause it to rotate to the position of the drain assembly 40 during the movement, and then be hit and squeezed by the drain assembly 40 during the continued movement, thus damaging the pressing member 33. The limit block 633 is set to limit the side of the pressing part 33 away from the button 50 during the movement of the upper cover 63, restricting the rotation of the pressing part 33 and preventing it from rotating to the position of the drain assembly 40. This protects the shape and position of the pressing part 33 and ensures the service life of the pressing part 33.

[0067] In one embodiment of the present invention, such as Figures 2 to 5 As shown, the basin assembly 1 also includes a drain pipe 70 and a mounting nut 80. The drain pipe 70 passes through the drain outlet 11, and the mounting nut 80 is located outside the water storage tank 10 and is connected to the drain pipe 70.

[0068] The installation of the drain pipe 70 facilitates the connection between the drain outlet 11 and the overflow pipe 41, and makes it easier for the overflow pipe 41 to block the drain outlet 11 and facilitate water discharge. On the other hand, it facilitates the connection between the drain outlet 11 and the outlet pipe. The installation of the drain pipe 70 is beneficial for the connection with the outlet pipe, improves work efficiency, and enhances the water discharge effect of the drain outlet 11. The drain pipe 70 has the effect of guiding and collecting water.

[0069] Furthermore, the connection between the mounting nut 80 and the drain pipe 70 can be a threaded connection. The mounting nut 80 can fix the water outlet pipe at the position of the drain outlet 11 to secure the water outlet pipe; on the other hand, it can adjust the position of the water outlet pipe at the drain outlet 11 to adjust the height of the water outlet pipe, thereby adjusting the water outlet position and water storage height.

[0070] In one embodiment of the present invention, such as Figures 2 to 7 As shown, the drainage assembly 40 includes an overflow pipe 41, a spring core 43, and a basket 45. The overflow pipe 41 is located above the drain pipe 70, and the basket 45 is located inside the drain pipe 70. The basket 45 has a movable groove 451 on the side facing the overflow pipe 41. One end of the spring core 43 is elastically connected to the overflow pipe 41, and the other end can be movably inserted into the movable groove 451. The transmission assembly 30 drives the overflow pipe 41 to open or block the drain pipe 70.

[0071] The drain assembly 40 includes an overflow pipe 41, which is located above the drain outlet 11. The overflow pipe 41 is a cylindrical body with openings at both ends. One end of the overflow pipe 41 is used to block the drain outlet 11, and the other end is used to connect to the transmission component. Therefore, when the drain assembly 40 is in a water storage state, when the water level is higher than the opening at the end connected to the transmission component, water can enter the overflow pipe 41 through the opening and flow out from the drain outlet 11, ensuring a certain water level and avoiding the problem of water flowing out of the basin due to excessive water level, thus improving hygiene.

[0072] Furthermore, such as Figure 7 As shown, the end of the overflow pipe 41 facing the transmission assembly 30 is also provided with a top shaft mounting seat 49 and a top shaft 47. The top shaft mounting seat 49 is connected to the end port of the overflow pipe 41 facing the transmission assembly 30 by a snap-fit. The top shaft mounting seat 49 is provided with a threaded hole in the middle. The screw is threadedly connected to the threaded hole, and then the screw is connected to the overflow pipe 41, and connected to the upper end of the overflow pipe 41. When the pressing element 33 rotates downward, it abuts against the upper end of the screw, and the screw is connected to the overflow pipe 41. The screw pushes the overflow pipe 41 downward, compressing the spring core 43 and blocking the drain outlet 11, thus sealing the channel between the water and the drain outlet 11. Water cannot flow out of the drain outlet 11 from the gap between the overflow pipe 41 and the drain outlet 11, achieving the state of water storage. When the pressing element 33 rotates upward, it disengages from the top of the overflow pipe 41. The overflow pipe 41 is rebounded by the spring core 43 and returns to its original position, moving upward and separating from the drain outlet 11. The screw rebounds to its original position and pushes the pressing element 33 and the button 50 back to their original positions. The overflow pipe 41 opens the channel between the water and the drain outlet 11, and water can flow out from the gap between the overflow pipe 41 and the drain outlet 11, achieving the state of water discharge.

[0073] Furthermore, when the button is pressed, the transmission component, overflow pipe 41, and spring core 43 all move downwards. The spring core 43 is pressed into the movable groove 451 of the basket 45, and the drain assembly 40 is in a water-filled state. When the button is pressed again, the spring core 43 is activated, bounced up, and reset. Consequently, the transmission component and overflow pipe 41 are lifted, and the sealing ring at the bottom of the overflow pipe 41 rises and leaves the drain pipe 70, allowing water in the water tank 10 to flow out through the drain outlet 11. The spring assembly allows the overflow pipe 41 and transmission component 30 to return to their initial positions after each button press, facilitating the opening of the overflow pipe 41 and the transition of the drain assembly 40 between the water-filled and draining states.

[0074] Furthermore, the basket 45 is installed inside the drain pipe 70, and the basket 45 is provided with multiple water passage holes, which can filter out debris and garbage passing through the drain pipe 70, so that the debris and garbage are separated by the water passage holes, and water passes through the water passage holes to prevent the debris and garbage from being discharged through the drain pipe 70, thereby improving the level of hygiene.

[0075] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
