Abstract
Description
Technical Field
[0001] This utility model relates to the field of concealed water tank technology, and in particular to a drainage panel and a concealed water tank. Background Technology
[0002] Currently, most concealed water tanks on the market use a push-button drive structure. By pressing a button on the control panel, a push rod is pushed to move linearly, and then the force is converted by the bracket assembly to open the drain valve to fully or partially drain the water.

[0037] Reference Figure 1-9 A drainage panel, comprising:
[0038] Panel bracket 100;
[0039] The pressing rod 200 is used to drive the drain valve 800 to drain water. Specifically, when the pressing rod 200 moves horizontally, it can drive the lifting rod 700 on the bracket assembly to move vertically, thereby lifting the sealing component in the drain valve 800 and completing the drainage action. The pressing rod 200 is connected to the drain valve 800 through the bracket assembly. The connection structure of the pressing rod 200, the bracket assembly and the drain valve 800 is existing technology and will not be described in detail here.
[0040] Button 300 is movably connected to panel bracket 100. The back of button 300 is provided with adjustment groove 310. Button 300 includes full row button 300 and half row button 300, each driving a pressing rod 200.
[0041] The lever 400 has one end hinged to the panel bracket 100 and the other end abutting against the pressing rod 200. The end of the pressing rod 200 is spherical to reduce friction between the pressing rod 200 and the lever 400 and prevent jamming. The pressing rod 200 can automatically reset after pressing, thereby resetting the lever 400 and the button 300 in conjunction.
[0042] An adjusting member 500 is installed in the adjusting groove 310. The adjusting member 500 abuts against the lever member 400, and the adjusting member 500 is located between the hinge axis of the lever member 400 and the pressing rod 200. The distance from the adjusting member 500 to the hinge axis can be changed by moving the adjusting member 500 along the adjusting groove 310. Specifically, both the adjusting groove 310 and the lever member 400 are arranged laterally. The distance between the adjusting member 500 and the hinge axis of the lever member 400 is the power arm of the lever member 400, and the distance between the pressing rod 200 and the hinge axis of the lever member 400 is the resistance arm of the lever member 400.
[0043] Working principle: Pressing button 300 causes the lever 400 to be lifted via adjusting component 500. Simultaneously, the pressing rod 200 at the other end of lever 400 is also lifted. Because the power arm of lever 400 is shorter than the resistance arm, the travel of pressing rod 200 is greater than the travel of button 300. The water sealing assembly of drain valve 800 is pulled upwards to the target distance, disengaging it from its sealed state and opening the drain channel, allowing water to drain smoothly from the tank. The position of adjusting component 500 can be moved along adjusting groove 310 to change the length of the power arm of lever 400, achieving fine adjustment of the transmission ratio between the pressing stroke and the opening amplitude of drain valve 800.
[0044] In some embodiments of this utility model, the button 300 is plate-shaped and located on the front side of the panel support 100. The button 300 is hinged to the panel support 100, and the lower end of the button 300 is tilted forward to provide space for the button 300 to deflect between its lower end and the panel support 100. The plate-shaped button 300 can completely cover the panel support 100 from the front, and the user can only see the button 300, resulting in a simple appearance. In this embodiment, the button 300 gradually curves forward in an arc from top to bottom, making the button 300 as a whole a curved plate shape, which achieves both the function of the button 300 and a refined appearance.
[0045] In some embodiments of this utility model, a first protrusion 320 is provided on the lower part of the back of the button 300, and a limiting groove 321 is provided on the first protrusion 320. A limiting post 110 is provided on the panel bracket 100, and the limiting post 110 is located in the limiting groove 321. Pressing the lower end of the button 300 can cause the limiting groove 321 to move relative to the limiting post 110. In the initial state, the limiting post 110 abuts against the rear end of the limiting groove 321. The limiting groove 321 is used to limit the flip angle of the button 300 to prevent the user from accidentally flipping the button 300 up.
[0046] In some embodiments of this utility model, a second protrusion 330 is provided on the upper part of the back of the button 300, and a pivot hole 331 is provided on the second protrusion 330. A first pivot post 120 is provided on the panel bracket 100, and the first pivot post 120 is inserted into the pivot hole 331 and has a clearance fit with the pivot hole 331. When the lower end of the button 300 is pressed, the button 300 will deflect around the first pivot post 120. Furthermore, a notch is provided on one side of the pivot hole 331, and the first pivot post 120 is inserted into the pivot hole 331 through the notch, which facilitates assembly.
[0047] In some embodiments of this utility model, the inner wall of the adjusting groove 310 is provided with serrations 311, which are arranged along the length of the adjusting groove 310. The adjusting member 500 is provided with positioning protrusions 510, the shape of which matches the shape of the serrations 311, and the positioning protrusions 510 are embedded in the serrations 311. The positioning protrusions 510 are triangular in shape and form a stable connection with the serrations 311, ensuring precise positioning and no positional deviation. The positioning protrusions 510 enable the adjusting member 500 to be precisely and accurately positioned on the adjusting groove 310, thereby achieving stepless adjustment of the transmission ratio.
[0048] In some embodiments of this utility model, the back of the button 300 is provided with a third protrusion 340, and an adjustment groove 310 is provided on the third protrusion 340. A clearance space is left on the front side of the adjustment groove 310. The adjustment member 500 includes a head 520 and an elastic latching part 530. The positioning protrusion 510 is located on the elastic latching part 530. The head 520 abuts against the lever member 400. The elastic latching part 530 is inserted into the adjustment groove 310 from back to front, and the front end of the elastic latching part 530 latches against the edge of the adjustment groove 310. Specifically, the head 520 is hemispherical, which abuts against the lever member 400 to avoid jamming. There are two elastic latching parts 530, one above the other, which respectively cooperate with the upper and lower walls of the adjustment groove 310. The adjustment member 500 and the adjustment groove 310 are connected by a latching mechanism, facilitating assembly.
[0049] In some embodiments of this invention, an elastic element is also included. The elastic element abuts against the panel support 100 and the lever 400, and provides a spring force to the lever 400 that tends to abut against the adjusting member 500. Although it was mentioned earlier that the lever 400 and the button 300 have an automatic reset function, in order to prevent the lever 400 or the button 300 from jamming and failing during reset, this invention provides an elastic element between the panel support 100 and the lever 400 to assist in reset.
[0050] In some embodiments of this utility model, the panel bracket 100 is provided with a mounting cavity 130, and a locking position 131 is provided in the mounting cavity 130. The elastic element is a spring sheet 600. One end of the spring sheet 600 has a hook structure 610 and extends into the mounting cavity 130 to engage with the locking position 131. The other end of the spring sheet 600 is bent, and the bent part forms an arc-shaped transition surface 620, which abuts against the lever element 400. The hook structure at one end of the spring sheet 600 is easy to form and convenient to assemble. The arc-shaped bending structure at the other end of the spring sheet 600 is easy to form and can reduce the friction between the spring sheet 600 and the lever element 400 through the arc-shaped transition surface 620, thereby reducing jamming.
[0051] In some embodiments of this utility model, a bushing 410 is formed at one end of the lever 400. An opening 411 is formed on the side wall of the bushing 410, penetrating the top and bottom of the bushing 410. A second pivot 140 is provided in the panel bracket 100. The second pivot 140 is inserted into the bushing 410 through the opening 411, allowing it to rotate within the bushing 410. The lever 400 can be molded from POM plastic, resulting in a smooth surface, good toughness, and low friction. The bushing 410, with its opening 411, facilitates assembly, and the lever 400 rotates smoothly without jamming.
[0052] A concealed water tank, including the aforementioned drain panel.
