[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The present invention provides a wired concealed panel drainage device, as shown in Figures 1 to 10, including a panel assembly 1, a transmission mechanism 2, a wired control mechanism 3, a drain valve body 41, and an inner core tube 42.

[0022] <Panel Assembly 1> The panel assembly 1 is used for embedding and installation on a wall or mounting surface, and is provided with at least one drainage button. As shown in Figures 3 and 4, in this embodiment, the panel assembly 1 is a split structure, including a panel body 11 and a panel mounting bracket 12. The panel mounting bracket 12 is used for fixed connection to the wall or mounting surface, and the panel body 11 is mounted on the panel mounting bracket 12 and embedded in the wall or mounting surface, with only its surface exposed.

[0023] The front surface of the panel assembly 1 has a button opening 111 for exposing the button, and the panel assembly 1 has a button pivot 112 inside. Specifically, the surface of the panel body 11 has a button opening 111 for exposing the button, the outer end of the button is located at the button opening 111, and the back of the panel body 11 has a button pivot 112. The two sides of the inner end of the button are rotatably connected to a button pivot 112. When the outer end of the button is pressed, it will rotate around the button pivot 112 to drive the transmission mechanism 2.

[0024] A button reset component is provided between the button and the housing of the panel assembly 1. Specifically, a button reset component is provided between the button and the panel body 11 to drive the button back to its initial position. Specifically, a button return spring 15 is sleeved on the button pivot 112, with both ends of the button return spring 15 abutting against the bottom of the button. When the force of pressing the button is removed, the elastic restoring force of the button return spring 15 drives the button to rotate in the opposite direction around the button pivot 112, so that the button returns to its initial position. In addition, a limit pin 16 is provided on each side of the middle part of the button to abut against the panel fixing frame 12 to prevent the button from excessively deflecting upward.

[0025] As shown in Figure 3, the button has a toothed structure 17 at the contact point with the top rod to disperse contact stress and improve the comfort and smoothness of transmission when pressing.

[0026] <Transmission Mechanism 2> The transmission mechanism 2 is disposed within the panel assembly 1 and is used to receive pressure from the button and transmit the pressure to the input end of the wired control mechanism 3. The transmission mechanism 2 includes a push rod linked to the button, a first swing rod 23 rotatably disposed within the panel assembly 1, and a push rod 24 slidably disposed; the push rod is used to receive pressure from the button and drive the first swing rod 23 to rotate; the first swing rod 23 is used to drive the push rod 24 to slide along a first direction (as shown by arrow A in Figures 2 and 6).

[0027] As shown in Figures 5 to 7, the cross-section of the first swing rod 23 is inverted L-shaped, consisting of a first branch 231, a second branch 232, and a rotating shaft 233. A rotating seat 121 is provided inside the panel fixing frame 12, and the first swing rod 23 is rotatably mounted inside the panel fixing frame 12 through the cooperation of the rotating shaft 233 and the rotating seat 121.

[0028] The first branch 231 of the first swing rod 23 is pivotally connected to the top rod. As shown in Figures 3 and 4, a pivot shaft 211 is provided on the top rod along its radial direction. Correspondingly, the first branch 231 has a U-shaped structure, and coaxial pivot holes are provided on both side walls of the U-shaped structure. The pivot shaft 211 is accommodated in the pivot hole, realizing the pivotal connection between the top rod and the first swing rod 23.

[0029] When the push rod is pressed down by the button, its movement trajectory is not purely linear because it is pivotally connected to the first swing rod 23. Instead, it is affected by the deflection force of the first swing rod 23, resulting in a slight oscillation towards the first swing rod 23. To address this, the panel mounting bracket 12 has an elliptical clearance hole 122, through which the lower end of the push rod passes. The major axis of the elliptical clearance hole 122 is aligned with the swing direction of the push rod, providing clearance space for the push rod to move towards the first swing rod 23 and preventing motion interference.

[0030] The second branch 232 of the first swing arm 23 passes through the clearance opening 123 below the panel fixing frame 12, extends to the outside of the panel fixing frame 12, and abuts against the push rod 24 movably disposed on the outside of the panel fixing frame 12.

[0031] When the push rod moves downward, the first branch 231 drives the first swing rod 23 to swing around the rotation axis 233, and the second branch 232 swings accordingly and pushes the push rod 24, causing the push rod 24 to slide along the first direction, thereby realizing the conversion and transmission of power from the vertical direction to the horizontal direction.

[0032] As shown in Figures 3 to 7, the second branch 232 is an arc-shaped structure with its center facing the push rod 24. Its end has a protrusion 2321 facing the push rod 24 and used to push against it. The protrusion 2321 maintains close contact with the input end of the push rod 24 at all times. When pushing the push rod 24 outwards, the contact surface between the protrusion 2321 and the input end of the push rod 24 gradually decreases.

[0033] The push rod 24 is movably disposed on the outside of the panel fixing bracket 12. Specifically, as shown in Figures 2 and 3, a columnar mounting base 124 is provided on the outside of the panel fixing bracket 12, and the push rod 24 is movably disposed in the mounting base 124. The input end and output end of the push rod 24 are respectively provided with a first limiting part and a second limiting part to prevent the push rod 24 from disengaging from the mounting base 124.

[0034] The first limiting part is a radial expansion head 241, located at the inner end of the mounting base 124, with an outer diameter larger than the inner diameter of the mounting base 124, to prevent the push rod 24 from coming out to the inner end; the second limiting part is a hook 242 structure, located at the outer end of the mounting base 124, which can be engaged with the outer end of the mounting base 124 to prevent the push rod 24 from coming out to the outer end.

[0035] In addition, the push rod 24 is also equipped with a push rod reset component, which is used to drive the push rod 24 to reset after the pressing pressure is removed. As shown in Figure 2, the push rod reset component is a reset spring 25, which is sleeved on the push rod 24, with one end abutting against the expansion head 241 of the push rod 24 and the other end abutting against the inner end of the mounting base. When the push rod 24 is subjected to pressing pressure from the first rocker arm 23, its expansion head 241 compresses the reset spring 25 towards the mounting base, causing deformation. When the pressing pressure is removed, the reset spring 25 is subjected to restoring force, pushing against the expansion head 241, so that the push rod 24 resets.

[0036] In this embodiment, the drainage device can achieve two different drainage volumes, corresponding to full drainage and half drainage functions respectively. The specific structure and working principle are as follows: the half-row button 13 and the full-row button 14 are arranged side by side on the panel body 11. Correspondingly, the top rod includes the half-row top rod 21 and the full-row top rod 22 arranged side by side.

[0037] The half-row push rod 21 is linked with the half-row button 13. When the half-row button 13 is pressed, it drives the half-row push rod 21 to move downward, as shown in Figure 6. The full-row push rod 22 is linked with the full-row button 14. When the full-row button 14 is pressed, it drives the full-row push rod 22 to move downward.

[0038] Two connecting parts are arranged side by side on the first branch 231 of the first swing arm 23: a half-row connecting part 2311 and a full-row connecting part 2312. The half-row connecting part 2311 is pivotally connected to the half-row top rod 21, and the full-row connecting part 2312 is pivotally connected to the full-row top rod 22. Therefore, whether the half-row button 13 or the full-row button 14 is pressed, the first swing arm 23 can be driven to swing through the corresponding top rod. This dual-input + single-output transmission method simplifies the structure and ensures that the two drainage modes share the same set of subsequent transmission mechanisms 2 (push rod 24, wired control mechanism 3, and drainage valve 4), reducing costs and improving reliability.

[0039] To differentiate between full-drainage and half-drainage drainage, this embodiment includes a limiting block 125 on the panel mounting bracket 12. As shown in Figure 4, the limiting block 125 is located on the displacement path of the half-row buttons 13, specifically below the half-row buttons 13, and is used to limit the maximum displacement distance of the half-row buttons 13 when they are pressed.

[0040] Half-drainage state: When the half-drainage button 13 is pressed, the half-drainage button 13 moves downward until it abuts against the limit block 125, at which point the half-drainage button 13 reaches its maximum stroke. Due to the obstruction of the limit block 125, the maximum displacement distance of the half-drainage button 13 is limited to the first displacement amount D1.

[0041] Full Drainage State: When the full drain button 14 is pressed, there is no limiting structure on the displacement path of the full drain button 14, so the full drain button 14 can continue to move downwards until its natural travel end. The maximum displacement distance of the full drain button 14 is the second displacement D2, and D2>D1.

[0042] The difference in button displacement distance is transmitted step by step through the transmission mechanism 2, and is ultimately reflected in the difference in the lifting height of the inner core tube 42, thereby achieving control over the drainage volume.

[0043] The wired control mechanism 3 is installed on the back of the panel assembly 1. Its output end is linked to the inner core tube 42 and is used to respond to the drive of the transmission mechanism 2 to control the inner core tube 42 to open or close the drain port 411 of the drain valve body 41. Specifically, as shown in Figures 8 to 10, the wired control mechanism 3 includes a wired control box 31, a second swing arm 32, a sleeve 33, a pull rope 34, and a third swing arm 35.

[0044] The wired control box 31 is a housing structure with a quick-release structure 36 on the housing. The quick-release structure 36 is connected to the mounting base 124 on the outside of the panel fixing bracket 12 to assemble the wired control box 31 onto the panel assembly 1.

[0045] The quick-release structure 36 can be any type of quick-release structure in the prior art, or it can be a quick-release structure integrated into the wired control mechanism. In this embodiment, as shown in Figures 10 and 11, the quick-release structure 36 includes a retainer 361, an elastic buckle 362, and a buckle reset member 363. A through hole 3611 is formed in the middle of the retainer 361. The through hole 3611 is fitted onto the neck of the mounting base 124 and is engaged and fixed by the elastic buckle 362 and the buckle reset member 363. When disassembly is required, pressing the elastic buckle 362 will release the lock. In addition, the through hole 3611 also serves as a channel for the push rod 24 to enter the wired control box 31.

[0046] The second swing arm 32 is rotatably mounted inside the control box 31, and has a V-shaped cross-section. Its input arm is linked to the output arm of the push rod 24, and its output arm is connected to one end of the pull rope 34. The second swing arm 32 is also equipped with a torsion spring 321 for driving it to reset.

[0047] The sleeve 33 is a flexible or semi-rigid hollow tube, one end of which is fixedly connected to the wired control box 31, and the other end is fixedly connected to the housing of the drain valve body 41. The sleeve 33 is used to accommodate and protect the pull rope 34, and guide the movement path of the pull rope 34. The pull rope 34 is a flexible traction member, which passes through the inside of the sleeve 33. One end is connected to the output end of the second swing rod 32, and the other end is connected to the input end of the third swing rod 35. The third swing rod 35 is rotatably mounted on the drain valve body 41, and has a V-shaped cross-section. Its input arm is connected to the other end of the pull rope 34, and its output arm is linked with the inner core tube 42 of the drain valve 4.

[0048] As shown in Figures 1, 2, and 8, the drain valve 4 includes at least a drain valve body 41 and an inner core tube 42. A drain port 411 is provided at the bottom of the drain valve body 41. A sealing plate 422 for sealing the drain port 411 is provided at the lower end of the inner core tube 42, and a lifting block 421 is provided at the upper end. The output arm of the third lever 35 is U-shaped, with the U-shaped output arm 351 encircling the outer wall of the inner core tube 42 and located below the lifting block 421 of the inner core tube 42.

[0049] Drainage Stage: When push rod 24 slides in the first direction driven by first swing rod 23, the output end of push rod 24 abuts against the input end arm of second swing rod 32, pushing second swing rod 32 to rotate. When second swing rod 32 rotates, its output end arm swings, pulling the pull rope 34 connected to it. Pull rope 34 transmits the traction force to the input end arm of third swing rod 35. The input end arm of third swing rod 35 is pulled by pull rope 34, driving third swing rod 35 to rotate. The output end arm of third swing rod 35 swings upward, and its U-shaped structure at the end pushes upward against the lifting block 421 of inner core tube 42, causing inner core tube 42 and float 43 to rise upward, thereby driving the water sealing plate 422 at the lower end of inner core tube 42 to leave the drain port 411 of drain valve 4, opening drainage.

[0050] Reset Phase: The button, transmission mechanism 2, and wired control mechanism 3 automatically reset after the pressing force is released, thus closing the drain outlet 411. Specifically: When the force of pressing the button is released, the push rod 24 slides back to reset under the action of the push rod 24 reset spring 25. The pushing force of the push rod 24 on the second swing rod 32 disappears, and the external force on the second swing rod 32, pull rope 34, and third swing rod 35 disappears. At this time, the second swing rod 32 gradually resets under the action of the restoring force of the torsion spring 321. At the same time, the inner core tube 42 descends and resets under its own weight. However, due to the buoyancy of the float 43, the descent speed of the inner core tube 42 slows down, and the drain outlet 411 does not close instantly but gradually, thus ensuring sufficient drainage time. During the reset process of the inner core tube 42, the third swing rod 35 is driven to rotate back to reset via the lifting block 421; the third swing rod 35 can also drive the second swing rod 32 to rotate back to reset via the pull rope 34. At this point, the entire wired control mechanism 3 returns to its initial state, waiting for the next operation.

[0051] When a small amount of water needs to be drained, pressing the half-drain button 13 results in a small lifting height of the inner core tube 42 and float 43 by the transmission mechanism 2 and the wire control mechanism 3, a short descent return time, a short opening time of the drain outlet 411, and a small amount of water drained. When a large amount of water needs to be drained, pressing the full-drain button 14 results in a large lifting height of the inner core tube 42 and float 43 by the transmission mechanism 2 and the wire control mechanism 3, a long descent return time, a long opening time of the drain outlet 411, and a large amount of water drained.
