The terms "upper," "lower," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, a flushing valve 1 is provided, comprising:

[0034] Water distribution valve 2, the water distribution valve 2 includes valve body 21, baffle 23, rotating shaft and swing arm 24, the valve body 21 is provided with water distribution cavity 22, the swing arm 24 is movably connected to the valve body 21 through the rotating shaft and the swing arm 24 is connected to the rotating shaft, the baffle 23 is located in the water distribution cavity 22, and the swing arm 24 can drive the baffle 23 to swing;

[0035] Main water pipe 3, which is connected to the water distribution chamber 22;

[0036] A flushing water pipe 4 is connected to the water distribution chamber 22, and the flushing water pipe 4 is provided with a limiting post 41;

[0037] The washing water pipe 5 is connected to the water distribution chamber 22. The baffle 23 can swing to close the flushing water pipe 4 or the washing water pipe 5, so as to discharge the water that enters the water distribution chamber 22 through the main water pipe 3 to the flushing water pipe 4 or the washing water pipe 5.

[0038] Water supply pipe 8, which is connected to and communicates with the outer wall of the flushing water pipe 4;

[0039] Float 6, which is movably connected to the limiting post 41;

[0040] The threaded rod 7 is threadedly connected to the float 6, and the end of the threaded rod 7 away from the float 6 is connected to the end of the swing arm 24 away from the rotating shaft.

[0041] In the prior art, the water supply pipe 8 is placed inside the flushing water pipe 4, which occupies the pipeline of the flushing water pipe 4 and results in loud noise during flushing. However, in this embodiment, the water supply pipe 8 is placed outside the flushing water pipe 4, which does not occupy the pipeline of the flushing water pipe 4 and reduces the noise during flushing. The float 6 and the swing arm 24 allow the water distribution valve 2 to switch between the flushing pipe 4 and the washing pipe according to the water level changes in the water tank 11. When the water level in the water tank 11 is high, the float 6 rises, causing the threaded rod 7 to rise. The threaded rod 7 then causes the swing arm 24 to rotate around the pivot, causing the baffle 23 to close the flushing pipe 4. During flushing, water in the main water pipe 3 can only be discharged from the washing pipe 5. As the water level in the water tank 11 drops, the float 6 begins to fall. The fall of the float 6 causes the threaded rod 7 to fall, and the threaded rod 7 then causes the swing arm 24 to rotate around the pivot, causing the baffle 23 to close the washing pipe 5. Water in the main water pipe 3 can only be discharged from the flushing pipe 4. This completes the switch from washing to flushing, ensuring the flushing effect of the toilet.

[0042] In some embodiments, such as Figure 1 and Figure 2As shown, the threaded rod 7 includes a threaded section 71, an extension section 72, and a retaining part 73. The threaded section 71 is threadedly connected to the float 6. One end of the extension section 72 is connected to the threaded section 71, and the other end is connected to the retaining part 73. The end of the swing arm 24 away from the rotating shaft is provided with a flat plate 241. The flat plate 241 is provided with a retaining groove 242 and a clearance opening 243. The clearance opening 243 communicates with the retaining groove 242. The extension section can enter the retaining groove 242 through the clearance opening 243. The cross-sectional width of the retaining groove 242 is smaller than the cross-sectional width of the retaining part 73 and the cross-sectional width of the threaded section 71.

[0043] The extension enters the retaining groove 242 through the clearance opening 243, and the cross-sectional width of the retaining groove 242 is smaller than the cross-sectional width of the retaining part 73 and the cross-sectional width of the threaded section 71, so that the threaded rod 7 can drive the swing arm 24 to swing when it rises or falls. This arrangement facilitates the assembly of the threaded rod 7 and the swing arm 24.

[0044] In some embodiments, the width of the clearance opening 243 is slightly larger than the width of the extension 72, as long as the extension 72 can pass smoothly through the clearance opening 243. The width of the clearance opening 243 is smaller than the width of the threaded section 71 and the retaining part 73, so as to prevent the threaded section 71 and the retaining part 73 from disengaging from the retaining groove 242 at the clearance opening 243.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the float 6 is provided with a limiting groove 61, and the limiting post 41 is inserted into the limiting groove 61. By setting the limiting groove 61 and the limiting post 41 to cooperate, the position of the float 6 is limited, ensuring that the float 6 moves only along the limiting post 41 during the process of floating or falling.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the cross-sectional shape of the limiting post 41 and the limiting groove 61 is cross-shaped to limit the deflection of the float 6 during floating or falling.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the water supply pipe 8 is inclined, and the axis of the water supply pipe 8 forms an angle with the axis of the flushing water pipe 4. This allows the water supply pipe 8 to be positioned as close as possible to the opening of the flushing water pipe 4, thereby accelerating the water supply speed.

[0048] In some embodiments, the included angle is ≥15° and ≤60°. The included angle between the axis of the water supply pipe 8 and the axis of the flushing water pipe 4 can be 15°, 30°, 45° or 60°, as long as it enables the water supply pipe 8 to be as close as possible to the opening of the flushing water pipe 4 to speed up the water supply speed, and will not be listed one by one here.

[0049] In some embodiments, the main water pipe 3, the flushing water pipe 4, and the washing water pipe are all integrally formed with the valve body 21. By integrally forming each water pipe with the valve body 21, assembly steps are reduced.

[0050] In some embodiments, such as Figure 3 and Figure 4 As shown, an embedded water tank is provided, including a tank body 11 and the aforementioned flush valve 1, wherein the flush valve 1 is installed inside the tank body 11.

[0052] Water is supplied to the water supply pipe 8 through the water inlet valve 10. After the water inlet valve 10 is filled with water, the water is transported to the water supply pipe 8 through the water supply channel 101. The water supply pipe 8 is connected to the toilet bowl of the toilet and supplies water to the toilet bowl to form a water seal.

[0053] In some embodiments, such as Figure 3 and Figure 4 As shown, the water tank body 11 includes a cover plate 111, a tank body 112, and a connecting sleeve 113. The cover plate 111 and the tank body 112 are connected. The flushing valve 1, the pressurizing pump 9, and the water inlet valve 10 are all located inside the tank body 112. The washing water pipe 5 extends out of the cover plate 111. The connector is connected to and communicates with the part of the washing water pipe that extends out of the cover plate 111.
