[0025] Example

[0026] Reference Figure 1-2 As shown, this utility model discloses a dual-button toilet drain valve, including a base 20 and a drain valve body 10. The drain valve body 10 is installed on the base 20. The base 20 has a drain hole 201 and a side opening on the side of the base 20. Water will flow in from the side opening and then enter the toilet through the drain hole 201.

[0027] Reference Figure 2-6As shown, the drain valve body 10, from top to bottom, includes a button, lever 104, inner core tube 105, base 106, and first float 107. The button is connected to the inner core tube 105 via lever 104. A water sealing plate 1053 is installed at the bottom of the inner core tube 105. The upper cover 101 has a large displacement button 103 and a small displacement button 102. The bottom of the small displacement button 102 has a first push block 1021 and a push rod 1022. The bottom of the large displacement button 103 has a second push block 1031. The first push block 102... 1. The top rod 1022 and the second push block 1031 can slide through the top cover 101. Specifically, the lever 104 includes a swing rod 1041 hinged to the bottom of the top cover 101 on both sides. One end of the swing rod 1041 is hinged to a lifting rod 1042. The other end of the lifting rod 1042 is movably connected to the inner core tube 105. When one end of the swing rod 1041 is pressed down and the other end is tilted up, the lifting rod 1042 is driven to lift the inner core tube 105 upward, which causes the water sealing plate 1053 to leave the drain hole 201, that is, to open the drain. When a small drainage volume is needed, press the small drainage button 102. This pushes the first push block 1021 downwards, pushing the swing rod 1041 and causing the lifting rod 1042 to lift the inner core tube 105 upwards, opening the sealing plate 1053 for drainage. Because a top rod 1022 is provided on the other side of the small drainage button 102, as the first push block 1021 pushes the swing rod 1041 upwards, the top rod 1022 also presses down to block the upward-raised end of the swing rod 1041, preventing the lifting rod 1042 from continuing to lift the inner core tube 105 upwards. That is, the inner core tube 105 drains water after being lifted a short distance. After releasing the small drainage button 102, the inner core tube 105 moves downwards, causing the sealing plate 1053 to cover the drain hole 201, completing the small drainage volume. When a large drainage volume is needed... When draining water, press the large discharge button 103 all the way down, push the swing rod 1041 to drive the lifting rod 1042 to lift the inner core tube 105 upward. The inner core tube 105 has a first protrusion 1051 on its side. The first float 107 is hinged to the drain valve body 10 on both sides. The first float 107 is equipped with a connecting rod 1071. After the inner core tube 105 is lifted upward, the first protrusion 1051 is locked in the connecting rod 1071, so that the sealing plate 1053 is fully opened. As the water level drops, the first float 107 tilts around the hinge point. When the water level drops to the lowest position, the first protrusion 1051 disengages from the connecting rod 1071, and the inner core tube 105 moves downward to cover the drain hole 201 with the sealing plate 1053, thus completing the large volume of water drainage. In addition, a pad 1061 is further provided on the chassis 106. The pad 1061 is located below the first float 107. As the water level drops, the bottom of the first float 107 will fall onto the pad 1061, which will play a buffering role.

[0028] Reference Figure 1-2 , Figure 5As shown, the drain valve body 10 has a water outlet 109 on its side, and the water outlet 109 is equipped with a movable baffle. Specifically, the size of the water outlet 109 is determined by adjusting the position of the baffle covering the water outlet 109. When the water outlet 109 is larger, the water flows out of the drain valve body 10 faster, that is, the first float 107 swings faster, so that the first protrusion 1051 of the inner core tube 105 can be disengaged from the connecting rod 1071 more quickly, thereby increasing the flushing speed of the toilet. Conversely, the water flows out slowly, the first float 107 swings slowly, and the water flow speed is slow.

[0029] Reference Figure 6 As shown, a frame 1011, a second float 108, and a scale 1010 are further provided inside the drain valve body 10. The frame 1011 is rotatably mounted on both sides of the inner wall of the drain valve body 10, and the scale 1010 is rotatably mounted on the side of the frame 1011. The second float 108 is installed below the scale 1010, and a second protrusion 1052 is provided on the side of the inner core tube 105. When water enters the water tank, the second float 108 moves upward under the action of buoyancy, causing the scale 1010 to move upward, thus making it convenient for the user to see the water level in the water tank.

[0030] Reference Figure 1 As shown, the base 20 is further provided with an overflow pipe 202. The upper end of the overflow pipe 202 is open, and the lower end is connected to the drain hole 201. When the water tank inlet valve is damaged and cannot be closed, the water flowing in will flow from the upper end of the overflow pipe 202 into the toilet, thereby achieving the function of automatic drainage.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
