Description

Technical Field

[0001] The present application relates to the field of toilets, and in particular to a toilet flushing system. Background Art

[0002] In some smart toilet tank overflow solutions, an overflow groove is set on the water tank to drain the water inside the water tank to the ceramic overflow port and flow into the ceramic pot surface, or the water in the water tank is directly overflowed into the ceramic.

[0003] Reference Figure 1 When the water tank needs to be equipped with an overflow groove, the ceramic overflow port is required to compromise in width or depth to accommodate the water tank overflow groove, which increases the volume of the ceramic body and causes the toilet to occupy a large space; and because space needs to be reserved for the overflow groove, the baffle design on the toilet cover is often bulky, which will also affect the overall aesthetics of the toilet; and when the toilet is blocked, sewage will also flow into the water tank through the water tank overflow groove, causing the water in the water tank to be contaminated.

[0004] Therefore, the present application designs a flushing system that can save the space occupied by the toilet, ensure the aesthetics of the toilet, and prevent the water in the water tank from being contaminated when the toilet is clogged. Utility Model Content

[0005] In order to save the space occupied by the toilet, ensure the aesthetics of the toilet, and avoid the water in the water tank from being contaminated when the toilet is clogged, the present application provides a toilet flushing system.

[0007] A toilet flushing system includes a toilet body, a water tank, a flushing pipe and an overflow pipe. The water tank is arranged around the toilet body. The toilet body also includes a brush ring opening. The flushing pipe is connected to the water tank and the brush ring opening; the overflow pipe is connected to the water tank and the brush ring opening. When the water tank overflows, the water in the water tank is discharged into the brush ring opening through the overflow pipe.

[0008] By adopting the above technical solution, the overflowing water in the water tank can be directly discharged into the brush ring opening through the overflow pipe, avoiding the additional space required for setting up an independent overflow tank, thereby saving the occupied space of the toilet and ensuring the aesthetics of the toilet; because the overflow is caused by setting up the overflow pipe, when the toilet body is blocked, the sewage will not overflow into the water tank, thereby avoiding the situation where the water in the water tank is contaminated when the toilet body is blocked.

[0009] Optionally, the flushing pipeline and the overflow pipeline are arranged in parallel. When the water tank overflows, the water in the water tank is discharged into the brush ring opening through the flushing pipeline and the overflow pipeline at the same time.

[0010] Optionally, a one-way valve is provided in the overflow pipeline. During flushing, the one-way valve closes the overflow pipeline, and during overflow, the one-way valve opens the overflow pipeline.

[0011] By adopting the above technical solution, it is possible to prevent flushing water from flowing back into the water tank through the overflow pipe during flushing.

[0012] Optionally, it includes a three-way pipe, two ends of which are respectively connected to the flushing pipe and the overflow pipe, and the other end is a water outlet pipe, the water outlet pipe is connected to the brush ring opening, and an installation cavity is provided between the overflow pipe and the three-way pipe, and the one-way valve is provided in the installation cavity; the one-way valve includes a plug body and a limiting rib, the plug body is connected to one end of the limiting rib, and a sealing gasket is provided on the plug body; during flushing, the plug body closes the overflow pipe, and the sealing gasket seals the overflow pipe, and during overflow, the plug body moves away from the overflow pipe, and water is diverted along the limiting rib and discharged into the brush ring opening through the water outlet pipe.

[0013] Optionally, the toilet body is provided with a ceramic overflow port, and the height of the water outlet pipe is higher than the ceramic overflow port.

[0016] By adopting the above technical solution, the overflow water flows through the second water passage and the first water passage in sequence through the water outlet of the outlet pipe, and is then discharged into the brush ring opening. Through the setting of the first water passage and the second water passage, a siphon is generated when the water overflows, accelerating the overflow speed.

[0017] Optionally, the flushing pipeline is provided with a water pump, and the water pump pumps water from the water tank to the flushing pipeline.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 2-10 This application is described in further detail.

[0039] The present application embodiment discloses a toilet flushing system. Figure 2 and Figure 3 The toilet flushing system includes a toilet body 1, a water tank 2, a flushing pipe 3, and an overflow pipe 4. The water tank 2 is arranged around the toilet body 1. In this embodiment, the water tank 2 is arranged below the toilet body 1, which can reduce the space occupied by the overall structure. The flushing pipe 3 connects the water tank 2 and the toilet bowl of the toilet body 1. During flushing, the water in the water tank 2 flows into the toilet bowl of the toilet body 1 through the flushing pipe 3. The toilet flushing system also includes a brush ring opening 5. In this embodiment, the flushing pipe 3 connects to the toilet bowl of the toilet body 1 through the brush ring opening 5, and the overflow pipe 4 connects the water tank 2 and the brush ring opening 5. When the water tank 2 overflows, the water in the water tank 2 is discharged into the brush ring opening 5 through the overflow pipe 4, avoiding the additional space required for an additional independent overflow tank. Therefore, it can save the space occupied by the toilet and ensure the aesthetics of the toilet.

[0040] Continue to refer to Figure 3In some embodiments, the flush line 3 and overflow line 4 are arranged in parallel. This parallel arrangement allows water to be discharged simultaneously through the flush line 3 and overflow line 4, thereby reducing the pressure on a single line and improving drainage efficiency. When the water tank 2 overflows, the water in the water tank 2 is discharged into the brush ring opening 5 through the flush line 3 and overflow line 4 simultaneously. This also provides multiple safeguards. Even if one line is blocked or fails due to a malfunction, the other line can still operate normally, ensuring the stability and reliability of the system.

[0041] Reference Figure 4 In some embodiments, a one-way valve 6 is provided in the overflow pipe 4. When flushing, the one-way valve 6 closes the overflow pipe 4. Closing the one-way valve 6 can prevent the flushing water from entering the overflow pipe 4 and flowing back into the water tank 2, causing insufficient water when flushing the toilet and affecting the flushing effect. Figure 5 When overflowing, the one-way valve 6 opens the overflow pipe 4, which can ensure that the water in the water tank can flow into the brush ring mouth 5 through the overflow pipe 4, preventing the water tank 2 from overflowing to the ground due to overfilling.

[0042] Reference Figure 6 In some embodiments, the toilet flushing system includes a three-way pipe 7, wherein two ends of the three-way pipe 7 are respectively connected to the flushing pipe 3 and the overflow pipe 4, and the other end is a water outlet pipe 8, which is connected to the brush ring opening 5. An installation cavity 9 is connected between the overflow pipe 4 and the three-way pipe 7, and a one-way valve 6 is arranged in the installation cavity 9. Both sides of the installation cavity 9 are covered with end covers 10.

[0043] Reference Figure 7 The one-way valve 6 includes a plug body 61 and a limiting rib 62. The plug body 61 is integrally connected to one end of the limiting rib 62, and a sealing gasket 63 is provided on the plug body 61. In this embodiment, four limiting ribs 62 are evenly spaced, and a flow channel 11 is formed between two adjacent limiting ribs 62. Figure 4 When flushing, the plug 61 closes the overflow pipe 4, and the sealing gasket 63 seals the overflow pipe 4, which can prevent the flushing water from flowing back into the water tank 2 and avoid affecting the flushing effect of the toilet. Figure 5 When overflowing, the plug body 61 moves away from the overflow pipe 4, and the water is guided along the flow channel 11 between the limiting ribs 62 and discharged into the brush ring port 5 through the water outlet pipe 8.

[0044] Reference Figure 5In some embodiments, the toilet flushing system further includes a brush ring body 12, which also includes a nozzle 28. The nozzle 28 is mounted on the brush ring opening 5 of the toilet body, which is connected to the brush ring body 12. The brush ring body 12 is sleeved on the water outlet pipe 8. In this embodiment, the brush ring body 12 and the water outlet pipe 8 are secured by a snap-fit connection. A gap is left between the inner wall of the brush ring body 12 and the outer wall of the water outlet pipe 8 to form a first water passage 26 connected to the brush ring opening 5. A gap is left between the inner wall of the brush ring body 12 and the water outlet of the water outlet pipe 8 to form a second water passage 27 connected to the first water passage 26. Overflow water flows through the water outlet of the water outlet pipe 8, sequentially through the second water passage 27, the first water passage 26, and the nozzle 28, and then into the brush ring opening 5. The arrangement of the first water passage 26 and the second water passage 27 creates a siphon when the water overflows, accelerating the overflow speed.

[0045] Reference Figure 6 In some embodiments, the flushing pipeline 3 is provided with a water pump 13. The overflow pipeline 4 is connected to the water inlet of the water pump 13 near the bottom, and the flushing pipeline 3 is connected to the water outlet of the water pump 13. When the water pump 13 is working, the flushing pipeline 3 is used for flushing. The water in the water tank 2 is pumped into the flushing pipeline 3 by the water pump 13, and then transported to the brush ring opening 5 for flushing. When the water pump 13 is not working, the flushing pipeline 3 is used for overflow. The water overflowing from the water tank 2 can flow through the water pump 13 and then flow into the flushing pipeline 3, so that the flushing pipeline 3 and the overflow pipeline 4 are connected in parallel, and the overflow water is discharged at the same time.

[0046] Refer again Figure 1 In some embodiments, the toilet body 1 is provided with a ceramic overflow port 14, and the height of the water outlet pipe 8 is higher than the ceramic overflow port 14. When the toilet body 1 is blocked, it can prevent sewage from returning to the water tank 2 to avoid contamination of the water in the water tank 2.

[0047] Reference Figure 8 In some embodiments, the toilet flushing system further includes a water inlet valve, which includes a solenoid valve 15 and a water inlet pipe 16. When the solenoid valve 15 is opened, water enters the water tank 2 through the water inlet pipe 16. The water inlet pipe 16 is provided with a water outlet 17. A distance is left between the water outlet 17 and the water tank 2 to avoid direct contact between the water outlet 17 and the water in the water tank 2, thereby avoiding contamination of the water source.

[0048] Reference Figure 8 and Figure 9 In some embodiments, a guide member 18 is provided at a position corresponding to the water outlet 17 of the water tank 2. The guide member 18 has a guide groove 19. The guide groove 19 is used to guide the incoming water. The water from the water outlet 17 can be guided along the guide groove 19 to the inner wall of the water tank 2, so that the noise during water inflow can be reduced. Figure 9In this embodiment, a fixing port 20 for fixing the water inlet pipe 16 is further provided on one side of the flow guide 18. In this embodiment, two fixing ports 20 are provided, so that the water inlet pipe 16 can be fixed and water can be inlet more stably.

[0049] Reference Figure 8 In some embodiments, the toilet flushing system further includes a liquid level sensor 21. In this embodiment, the liquid level sensor 21 is disposed on the guide member 18 and is located inside the water tank 2 and is used to detect the water level in the water tank 2 and control the opening and closing of the water inlet valve according to the water level. When the water in the water tank 2 reaches the liquid level sensor 21, the water inlet is stopped, thereby being able to control the water inflow of the water tank 2. Figure 10 In this embodiment, a mounting opening 22 is provided at the bottom of the flow guide member 18 , and the liquid level sensor 21 is fixed to the mounting opening 22 .

[0050] The implementation principle of a toilet flushing system in an embodiment of the present application is as follows: water overflowing from the water tank 2 can be directly discharged into the brush ring opening 5 through the overflow pipe 4, avoiding the additional space required for setting up an independent overflow trough, thereby saving the occupied space of the toilet and ensuring the aesthetics of the toilet; since overflow is caused by setting up the overflow pipe 4, when the toilet body 1 is blocked, sewage will not overflow into the water tank 2, thereby avoiding the situation where the water in the water tank 2 is contaminated when the toilet body 1 is blocked.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
