DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, a water-saving device for a toilet water tank according to an embodiment of the present utility model includes a water tank 11, a tank cover 12, a wall-wetting button 21, a drain valve 3, and a wall-wetting pressure rod 22. The drain valve 3 is arranged in the water tank 11, the tank cover 12 is arranged at the upper end opening of the water tank 11, the wall-wetting button 21 is arranged on the tank cover 12, and the upper end of the wall-wetting pressure rod 22 is connected to the wall-wetting button 21;

[0025] The drain valve 3 includes a full-row button 31, a half-row button 32, a lever structure 33 and a drain switch 34. A limiting cylinder is provided at the lower end of the half-row button 32. The lower end of the wall-lubricating pressure rod 22 is located above the middle of the full-row button 31 and the half-row button 32. The full-row button 31 and the half-row button 32 are both transmission-connected to the upper end of the lever structure 33. The lower end of the lever structure 33 is connected to the drain switch 34. The drain switch 34 is used to be set at the drain outlet.

[0026] Specifically, if Figures 1 to 4 As shown, the box cover 12 is also provided with a full row of buttons 23, which is connected to the full row of buttons 31 via a full row pressure rod 24; the box cover 12 is also provided with a half row of buttons 25, which is connected to the half row of buttons 32 via a half row pressure rod 26. Secondly, the full row of buttons 23, the half row of buttons 25 and the wall-wetting button 21 are set to fluorescent material, which can emit bright light in a dark environment, making it easy to observe and use.

[0027] In this embodiment, by pressing the full-drain button 23 on the box cover 12, the full-drain pressure rod 24 can be used to press the full-drain button 31. When the full-drain button 31 moves downward, it drives the lever structure 33, thereby pulling the drain switch 34 upward to open the drain outlet, thereby achieving full drainage.

[0028] By pressing the half-row button 25 on the box cover 12, the half-row pressure rod 26 can be used to press the half-row button 32. The half-row button 32 moves downward to drive the lever structure 33, thereby pulling the drain switch 34 upward to open the drain outlet. Since a limiting cylinder is provided at the lower end of the half-row button 32, the lever structure 33 can be limited. Therefore, the distance that the drain switch 34 moves upward during the half-drain process is smaller than the distance that the drain switch 34 moves upward during the full-drain process, thereby achieving half-drain.

[0029] By pressing the wall-wetting button 21 on the box cover 12, the pressure rod can be driven down. The wall-wetting pressure rod 22 is arranged above the middle of the full-row button 31 and the half-row button 32. The wall-wetting pressure rod 22 can be used to press the full-row button 31 and the half-row button 32 at the same time. When the full-row button 31 and the half-row button 32 are pressed down at the same time, due to the limiting effect of the limiting cylinder on the lever structure 33, it is equivalent to pressing only the half-row button 32, that is, by pressing the wall-wetting button 21, the stroke of the drain switch 34 is only equivalent to the stroke of half a row, then the water output of the drain valve 3 during the wall-wetting process is only equivalent to the water output of the drain valve 3 during the half-row process, which is beneficial to reduce the water consumption for wall-wetting, thereby reducing the cost of use.

[0030] Alternatively, as Figure 3 and Figure 4 As shown, the drain valve 3 also includes a full row of floats 35, a half row of floats 36, a full row of cams 351, a half row of cams 361, a full row of brackets 352, a half row of brackets 362 and a height adjustment tooth 353. The full row of floats 35 is slidably connected to the height adjustment tooth 353. The full row of cams 351 and the half row of cams 361 are provided on the lever structure 33. The full row of floats 35 is connected to the full row of brackets 352. The full row of brackets 352 is used to dock with the full row of cams 351, and the half row of brackets 362 is docked with the half row of cams 361.

[0031] In this embodiment, when water is stored in the water tank 11, both the full row of floats 35 and the half row of floats 36 float.

[0032] During the half-drain process, when the water tank 11 is draining, pressing the half-drain button 25 drives the half-drain button 32 to pull the lever structure 33 upward, driving the half-drain convex buckle 361 to buckle on the half-drain bracket 362, the lever structure 33 is limited, and the drain switch 34 moves up and opens to discharge water; when the water level drops to the half-drain buoy 36, the half-drain buoy 36 is linked to the half-drain bracket 362 to deflect under the action of gravity, the lever structure 33 loses its buckle and falls back to its original position, and the drain switch 34 falls back to the drain outlet, completing the half-drain flushing; during the half-drain process, when the water tank 11 is storing water, water enters the water tank 11, and the drain switch 34 pulls the lever structure 33 to move vertically downward.

[0033] During the full flushing process, when the water tank 11 is draining, pressing the full drain button 23 drives the full drain button 31 to pull the lever structure 33 upward, driving the full drain convex buckle 351 to buckle on the full drain bracket 352, the lever structure 33 is limited, and the drain switch 34 moves up and opens to discharge water; when the water level drops to the full drain float 35, the full drain float 35 is linked to the full drain bracket 352 to deflect under the action of gravity, the lever structure 33 loses its buckle and falls back to its original position, and the drain switch 34 falls back to the drain outlet, completing the full flushing process; during the full flushing process, when the water tank 11 is storing water, the water tank 11 is filled with water, and the drain switch 34 pulls the lever structure 33 to move vertically downward.

[0034] Thus, by configuring the drain valve 3 to include a full-row float 35, a half-row float 36, a full-row protrusion 351, a half-row protrusion 361, a full-row bracket 352, and a half-row bracket 362, full and half-row drains can be achieved. Furthermore, by providing a height adjustment tooth 353, the height of the full-row float 35 on the height adjustment tooth 353 can be adjusted to control the water output of the full drain.

[0035] Alternatively, as Figures 2 to 4 As shown, the water-saving device of the toilet tank further includes a sterilization box 4 , which is mounted on the tank cover 12 and located in the water tank 11 , and contains mosquito repellent and sterilization liquid.

[0036] In this embodiment, the sterilization box 4 is connected to the inside of the box cover 12, and mosquito repellent and sterilization liquid is placed in the sterilization box 4, which can be used to solve the problem of mosquito bites.

[0037] Alternatively, as Figure 2 and Figure 5As shown, the water-saving device of the toilet water tank also includes an inlet valve 5, which includes an upper sleeve 51, a lower sleeve 52, a turntable 53 and a latch 54. The inner wall of the upper sleeve 51 is slidably connected to the outer wall of the lower sleeve 52. The outer wall of the lower sleeve 52 is provided with an external thread, and the inner wall of the turntable 53 is provided with an internal thread. The turntable 53 is rotatably connected to the lower sleeve 52 through the internal and external threads. The latch 54 is slidably connected to the upper sleeve 51, and the lower end of the latch 54 is used to connect with the turntable 53.

[0038] In this embodiment, by pulling out the pin 54 from the turntable 53, the threaded connection between the turntable 53 and the lower sleeve 52 can be achieved through the internal thread of the turntable 53 and the external thread on the lower sleeve 52. The turntable 53 is connected to the lower end of the upper sleeve 51, which can drive the upper sleeve 51 to extend and retract relative to the lower sleeve 52.

[0039] By inserting the pin 54 into the turntable 53, the turntable 53 can be fixed to prevent the turntable 53 from rotating relative to the lower sleeve 52, thereby preventing the upper sleeve 51 from expanding or contracting relative to the lower sleeve 52, and positioning the height of the upper sleeve 51 relative to the lower sleeve 52, thereby achieving adjustment of the water level in the water tank 11.

[0040] Alternatively, as Figure 6 As shown, a plurality of circumferentially distributed slots 531 are provided on the inner wall of the turntable 53 , and the lower end of the latch 54 is used to be inserted into the slot 531 .

[0041] In this embodiment, a plurality of slots 531 are provided on the inner wall of the turntable 53. The turntable 53 is rotated to cause the upper sleeve 51 to extend and retract relative to the lower sleeve 52, and the lower end of the latch 54 is inserted into a slot 531 to position the turntable 53. Thus, by pulling the lower end of the latch 54 out of the slot 531, the height of the upper sleeve 51 can be adjusted, and by inserting the lower end of the latch 54 into the slot 531, the height of the upper sleeve 51 can be positioned. The water inlet valve 5 can be adjusted directly in the water tank 11, without having to remove the water inlet valve 5 from the water tank 11 and then adjust the water level in the water tank 11, thus facilitating user operation.
