[0020] like Figure 1-3As shown, the tower-type drain valve described in this embodiment includes a button mechanism 1 and a valve body mechanism 2. The button mechanism 1 includes a seat ring 3, a button ring 4, a button body 5, a core tube 6, a first clamping plate 7 screwed onto the core tube 6, a lifting rod 8 coaxially installed inside the core tube 6, and a detachable active pressure plate 9 located at the lower end of the lifting rod 8. The seat ring 3 is coaxially installed outside the core tube 6 and, after installation, snaps into the opening of the toilet tank lid. The outer ring of the button ring 4 overlaps the seat ring 3, and the button ring 4 also has multiple claws 10 evenly distributed circumferentially. The upper edge of the core tube 6... A slot is provided to cooperate with the aforementioned claw 10. The button ring 4 is coaxially engaged with the upper edge of the core tube 6. The button body 5 is coaxially mounted in the button ring 4 through the ring edge. The button body 5 can be pressed down into the button ring 4. An elastic element 11 is provided between the lifting rod 8 and the core tube 6 to make the lifting rod 8 rise. Specifically, a cap post 12 is fixed at the upper end of the lifting rod 8. The cap post 12 is inserted into the button body 5. The lower end of the lifting rod 8 is screwed onto the active pressure plate 9. The elastic element 11 is a compression spring sleeved on the lifting rod 8 between the cap post 12 and the core tube 6.

[0021] The lifting rod 8 is also equipped with a vertical guide slider 13, and the core tube is equipped with a guide groove that cooperates with the vertical guide slider 13.

[0022] Valve body mechanism 2 includes valve seat 14, lever 15 hinged to valve seat 14, and active member 16 and passive member 17 slidably mounted on valve seat 14. A water outlet pipe 18 is connected to the bottom surface of valve seat 14. A second pressing plate 19 is screwed onto the water outlet pipe 18, and a sealing ring 20 that mates with the second pressing plate 19 is also fitted onto it. An adjusting rod 21 is screwed onto the active member 16, and a passive pressing plate 22 corresponding to the active pressing plate 9 is screwed onto the adjusting rod 21. A limit plate 23 is also screwed onto the adjusting rod 21. After adjusting the height of the passive pressing plate 22 by screwing the adjusting rod 21, the limit plate 23 can be pressed against the passive pressing plate 22. The dynamic pressure plate 22; the lever 15 is U-shaped, and the bottom left and right sides of the active member 16 are respectively equipped with connecting rods 24 between the two ends of the lever 15. The two ends of the connecting rods 24 are respectively connected to the active member 16 and the lever 15. The passive member 17 is equipped with a lever plate 25 that cooperates with the lever 15. Specifically, the passive member 17 is equipped with an annular groove, and the lever plate includes a clamp that cooperates with the annular groove and a lever plate body fixed on the clamp. The lower end of the passive member 17 is connected to a water outlet pipe plug 26. The water outlet pipe plug 26 includes an upper pressure plate, a lower pressure plate and a sealing plate located between the upper and lower pressure plates. The sealing plate can cover the inlet of the water outlet pipe 18.

[0023] The passive component 17 is tubular, with its upper part extending into the active component 16, and the lower part of the aforementioned adjusting rod 21 extending into the passive component 17, so that there is no interference when it moves up and down.

[0024] To reduce friction between lever 15 and lever 25, a horizontal roller shaft that cooperates with lever 25 is installed on lever 15. When lever 15 is raised and contacts lever 25, the horizontal roller shaft rotates, changing sliding friction to rolling friction and extending the service life of lever 15 and lever 25.

[0025] The working principle of this embodiment is as follows:

[0026] When the valve body mechanism 2 is installed, the valve seat 14 is placed in the reserved hole inside the toilet tank. The second clamping plate 19 and the valve seat 14 are clamped to the toilet tank to fix the valve body mechanism 2. When the button mechanism 1 is installed, the seat ring 3 is placed in the reserved hole inside the toilet tank cover. The first clamping plate 7 and the seat ring 3 are clamped to the toilet tank cover to fix the button mechanism 1.

[0027] When in use, press the button body 5. After releasing, the button body 5 automatically returns to its original position under the action of the compression spring. When the button body 5 moves down, the lifting rod 8 and the active pressure plate 9 move down. The active pressure plate 9 drives the passive pressure plate 22 to move down, and the passive pressure plate 22 drives the active component 16 to move down. The active component 16 presses down the end of the lever 15 through the connecting rod 24. The bent part of the lever 15 rises and contacts the lever plate 25. The lever plate 25 is lifted, which in turn drives the passive component 17 to rise. The water outlet pipe plug 26 leaves the inlet of the water outlet pipe 18, and the water can be discharged through the water outlet pipe 18. After releasing, the passive component 17... 7. Under its own gravity, it moves downward, pressing down the bent part of the lever 15. The end of the lever 15 lifts the active member 16 through the connecting rod 24, and the passive pressure plate 22 returns to the initial position. This embodiment proposes a drain valve with a new action structure. The downward movement of the active member 16 drives the lever 15 to rise, thereby lifting the passive member 17 and the water pipe plug 26, and opening the water outlet pipe 18 channel. Compared with the prior art, this embodiment has a simple structure and reliable operation. It can effectively reduce the volume of the drain valve, which is conducive to later installation, disassembly and maintenance, and has strong practicality.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
