Inlet 50, siphon water outlet 54, the flushing water outlet 50 is a normally open water outlet, the flushing water outlet 50 is connected to the flushing water circuit inside the toilet, the water suction port 11 of the flushing water outlet flushing valve 33 is connected to the inlet end of the impeller pump 34, the water replenishment port 13 of the flushing valve 33 is connected to the siphon water outlet 54 of the on-off valve 35, the water inlet of the on-off valve 35 is connected to the water outlet end of the impeller pump 34, and the water circuit connected between the water tank 12 and the flushing water outlet 01 is formed with a water sealing ring 22 and a water control component that automatically and / or manually controls the sealing or conduction of the water circuit at the water sealing ring 22.

[0033] In this embodiment, Figure 1 , Figure 5 and Fig. 9As shown, the water tank 12 is installed on the toilet bowl of the toilet and is used to store water required for flushing. The flush valve 33 is provided with a flush port 01, a water replenishment port 13, and a water suction port 11. The flush port 01 pipeline intersects with the sewage outlet pipeline of the toilet and is sealed and connected to the sewer. A negative pressure chamber 20 is provided inside the flush valve 33, and the negative pressure chamber 20 is connected to the water suction port 11. A water sealing ring 22 is arranged on the water path of the flush port 01. The water control component is used to automatically and / or manually control the sealing or conduction of the water path at the water sealing ring 22. When When the water control component is in the on state, water passes through the water sealing ring 22 and is flushed out from the flushing port 01, and then discharged to the intersection with the toilet sewage outlet and flows away from the sewer, and a negative pressure is generated at the intersection of the sewage outlet pipe and the flushing port 01 pipe, thereby sucking out the sewage and debris inside the toilet from the sewage outlet and draining them from the sewer. The greater the water volume of the flushing port 01, the greater the negative pressure generated, and the better the sewage discharge effect of the toilet. When the water control component is in a sealed state, the water is sealed in the water tank 12 and will not flow out. In case of power failure or other special circumstances, the water control component can be manually operated to set the water path at the water sealing ring 22 to the conducting state, and water is directly discharged from the flushing port 01 to the sewer through the water sealing ring 22. At this time, the impeller pump 34 does not work, but the system can still ensure the normal sewage discharge function. The on-off valve 35 is provided with a water inlet, a flushing water port 50, and a siphon water port 54. The flushing water port 50 is a normally open water port. The water inlet of the on-off valve 35 is connected to the water outlet of the impeller pump 34. When the impeller pump 34 is working, it can supply water to the flushing water port 50 and the siphon water port 54. The water inlet 54 transports water, the water supply port 13 of the flush valve 33 is connected to the siphon water inlet 54 of the on-off valve 35, and the flushing water inlet 50 is connected to the flushing water path of the toilet, so that the inner wall of the toilet bowl can be flushed, and the debris is gathered to the sewage outlet of the toilet bowl.

In this way, the water absorption capacity of the sewage outlet is stronger, and the sewage and debris inside the toilet bowl are more easily sucked into the sewer, and the sewage discharge effect of the toilet bowl is better.

[0034] Example 2

[0035] Furthermore, the impeller pump 34 has two water pumping chambers 37 which are relatively distributed up and down, each water pumping chamber 37 corresponds to an inlet end, and there are two inlet ends, namely a first inlet end 36 and a second inlet end 41.

Impellers 39 are provided in the water pumping chambers 37, and the two impellers 39 are respectively connected to the two ends of the rotating shaft 40 of the impeller pump 34.

[0036] In this embodiment, the impeller pump 34 has two water pumping chambers 37 relatively distributed up and down. This design can balance the working pressure of the pump, reduce vibration and noise, and improve the efficiency and stability of water pumping. Each water pumping chamber 37 corresponds to an inlet end, so there are two inlet ends in total: a first inlet end 36 and a second inlet end 41. The two inlet ends absorb water at the same time to increase the amount of water pumped. The two water pumping chambers 37 are connected to each other through a water outlet channel 43 to form a complete circulation system. The water outlet is connected to the water outlet channel 43 to transport the pressurized water to the water inlet of the on-off valve 35. Each water pumping chamber 37 is provided with an impeller 39. The two impellers The wheels 39 are respectively connected to the two ends of the rotating shaft 40 of the impeller 39. When the rotating shaft 40 rotates, the two impellers 39 will rotate synchronously, thereby generating a strong centrifugal force in the water pump chamber 37, sucking in the water flow from the inlet end and pressurizing it before discharging it through the outlet. The water flows into the two water pump chambers 37 through the two inlet ends respectively. As the rotating shaft 40 rotates, the impeller 39 starts to work, pressurizes the water flow and pushes it to flow through the outlet channel 43 to the outlet, and then more water enters the flushing port 01, thereby making the negative pressure generated at the intersection of the toilet sewage outlet pipeline and the flushing port 01 pipeline stronger, the stronger the siphoning ability of the sewage and debris inside the toilet, and the better the sewage discharge effect of the toilet.

[0037] Example 3

[0038] Furthermore, the water outlet is provided with a first water outlet 42 , which is connected to one end of the water outlet channel 43 , and the on-off valve 35 is provided with a water inlet 52 connected to the first water outlet 42 .

The on-off valve 35 then supplies water to the flushing water outlet 50 and the siphon water outlet 54 respectively.

[0040] Example 4

[0041] Furthermore, the water outlet is provided with two, namely the second water outlet 59 and the third water outlet 60, the second water outlet 59 and the third water outlet 60 are respectively connected to the two ends of the water outlet channel 43, and the on-off valve 35 is provided with two water inlets respectively connected to the second water outlet 59 and the third water outlet 60, namely the second water inlet 61 and the third water inlet 62.

[0042] In this embodiment, Figure 8 and Figure 7 As shown, the impeller pump 34 has two water outlet ends, namely the second water outlet 59 and the third water outlet 60. The second water outlet 59 is located above the third water outlet 60. The water at the first inlet end 36 is transported to the third water outlet 60, and the third water outlet 60 is connected to the third water inlet 62 on the on-off valve 35. The water at the second inlet end 41 is transported to the second water outlet 59, and the second water outlet 59 is connected to the second water inlet 61 on the on-off valve 35. The water from the second water inlet 61 and the third water inlet 62 are collected together, and the on-off valve 35 then supplies the water to the flushing water outlet 50 and the siphon water outlet 54 respectively.

[0043] Example 5

[0044] Furthermore, the on-off valve 35 includes a valve body 58, a valve core 53, and a first valve seat 48. The water inlet, the siphon water port 54 and the flushing water port 50 are all arranged on the valve body 58. The valve core 53 is rotatably arranged in the valve body 58. The first valve seat 48 is arranged at the bottom of the valve body 58 and seals the valve core 53 in the valve body 58. The first valve seat 48 is bolted to the valve body 58. The siphon water port 54 and the flushing water port 50 are arranged opposite to each other. The middle part of the valve core 53 is a cavity, and the cavity is connected to the water inlet. The side wall of the valve core 53 is circumferentially provided with a first water through hole 51 and a third water through hole 63 connected to the cavity. The water path connected to the first water through hole 51 and the flushing water port 50 remains normally open, and the valve core 53 rotates to control the connection or closure of the water path between the third water through hole 63 and the siphon water port 54.

[0045] In this embodiment, Figure 2 and Figure 6As shown, the valve body 58 is the main part of the entire on-off valve 35, and the water inlet, siphon water port 54 and flushing water port 50 are all arranged on it. These interfaces are respectively connected to the water outlet end of the impeller pump 34, the water replenishment port 13 of the flushing valve 33 and the flushing system of the toilet. The valve core 53 is a key component of the on-off valve 35. It is rotatably arranged in the valve body 58. The rotation of the valve core 53 controls the on-off and flow direction of the water flow. The middle part of the valve core 53 is designed as a cavity, which is connected to the water inlet so that pressurized water can enter the inside of the valve core 53. The first valve seat 48 is arranged at the bottom of the valve body 58. The valve core 53 is enclosed in the valve body 58. This design ensures the stability and sealing of the valve core 53 during the rotation process. The first valve seat 48 and the valve body 58 are connected by bolts, which is convenient for installation and disassembly, and also improves the reliability of the connection. The siphon water inlet 54 and the flushing water inlet 50 are arranged relatively on the valve body 58. This layout is conducive to optimizing the water flow path and reducing the water flow resistance. The flushing water inlet 50 is designed as a normally open water inlet to ensure that the water flow can smoothly flush the inner wall of the toilet when flushing is required. The side wall of the valve core 53 is circumferentially provided with a first water hole 51 and a first water hole 52 connected to the cavity. The three water holes 63 play a key role in the rotation of the valve core 53. The water path connected to the flushing water port 50 by the first water hole 51 is kept open, which means that no matter how the valve core 53 rotates, the flushing water port 50 can obtain a stable water supply. The connection or closure of the water path between the third water hole 63 and the siphon water port 54 is controlled by the rotation of the valve core 53. When the third water hole 63 is connected to the siphon water port 54, water can flow into the water supply port 13 of the flushing valve 33; when the third water hole 63 is closed, this water path is blocked. When the impeller pump 34 is working, During operation, pressurized water enters the cavity of the valve core 53 through the water inlet. No matter how the valve core 53 rotates, the first water hole 51 remains normally open, so that water always flows out of the flushing water outlet 50 for flushing. By rotating the valve core 53, it is possible to control whether the water path between the third water hole 63 and the siphon water outlet 54 is connected. When water replenishment is required, the valve core 53 is rotated to the connected state; when water replenishment is not required, the valve core 53 is rotated to the closed state. The normally open design of the flushing water outlet 50 ensures the reliability of the flushing function, and the on-off control of the siphon water outlet 54 is simple and convenient, and easy to operate and maintain.

[0046] Furthermore, the valve core 53 is in the shape of a cone with a small upper end and a large lower end. The lower end of the valve core 53 is adapted to be clamped to the first valve seat 48 via a clamping block 56. A pressure ring 55 is embedded in the bottom of the valve core 53. A spring 46 is provided between the pressure ring 55 and the first valve seat 48. One end of the spring 46 acts on the bottom of the valve core 53, and the other end acts on the top of the first valve seat 48.

[0047] Specifically, the valve core 53 is in the shape of a cone with a small upper end and a large lower end. This design helps to form a tighter seal between the valve core 53 and the first valve seat 48. When the valve core 53 rotates to the closed position, the larger diameter at its lower end can better fit the first valve seat 48, reducing the possibility of leakage and reducing the number of sealing rings on the valve core 53. This reduces the resistance of the valve core 53 during rotation, thereby reducing the load on the drive motor 44 and thus reducing the operating cost of the drive motor 44. The lower end of the valve core 53 is adapted to be connected with the first valve seat 48 through a clamping block 56. This clamping method not only ensures the stable rotation of the valve core 53 in the valve body 58, but also prevents the valve core 53 from accidentally coming out or shifting when it is impacted by water flow. A pressing ring 55 is embedded at the bottom of the valve core 53. A spring 46 is arranged between the pressing ring 55 and the first valve seat 48. One end of the spring 46 acts on the bottom of the valve core 53, and the other end acts on the top of the first valve seat 48, forming an elastic support system. The main function of this spring 46 system is to keep the valve core 53 in a certain position (such as the default closed position) when the valve core 53 is not subjected to external force. At the same time, the elastic force of the spring 46 also helps to enhance the connection between the valve core 53 and the first valve seat 48 when the valve core 53 rotates to the closed position. 8, when it is necessary to control the on and off of the water flow, the valve core 53 is rotated in the valve body 58, and the rotation of the valve core 53 will change the relative position relationship between the first water through hole 51 and the third water through hole 63 and the siphon water outlet 54 and the flushing water outlet 50. When the valve core 53 rotates to the position where the third water through hole 63 is connected to the siphon water outlet 54, water can enter the valve core 53 cavity through the water inlet, and then flow into the siphon water outlet 54 through the third water through hole 63 to replenish the water tank 12. When the valve core 53 rotates to the closed position, the third water through hole 63 is closed, and water cannot flow into the siphon water outlet 54; at the same time, due to the conical shape of the valve core 53 and the elastic force of the spring 46, a tight seal is formed between the valve core 53 and the first valve seat 48 to prevent water leakage.

[0048] Furthermore, a driving motor 44 is provided at the bottom of the first valve seat 48, and an output shaft 45 of the driving motor 44 passes through the first valve seat 48 and is connected to the middle of the bottom surface of the valve core 53. The pressure ring 55 and the spring 46 are located on the outside of the output shaft 45. The first valve seat 48 is circumferentially provided with a circle of grooves 49, and a first sealing ring 47 is embedded in the groove 49. A second sealing ring 57 is pressed between the first valve seat 48 and the valve core 53.

[0049] Specifically, Figure 2 and Figure 6As shown, a driving motor 44 is provided at the bottom of the first valve seat 48, and the rotation of the valve core 53 can be automatically controlled by electric drive. The output shaft 45 of the driving motor 44 passes through the first valve seat 48 and is connected to the middle of the bottom surface of the valve core 53, directly providing power for the rotation of the valve core 53. This connection method ensures the effective transmission of power and the precise control of the rotation of the valve core 53. Bearings 38 are installed at both ends of the output shaft 45. The pressure ring 55 and the spring 46 are located on the outside of the output shaft 45 of the driving motor 44. They act together on the bottom of the valve core 53 to provide stable support and buffering for the valve core 53. The existence of the spring 46 can also offset the impact of water flow on the valve core 53 to a certain extent, thereby improving the stability and durability of the valve. A circle of grooves 49 is provided, and a first sealing ring 47 is embedded in the groove 49. This design increases the sealing area and sealing effect between the valve seat and the valve body 58 or other components, and prevents water from leaking out from the gap between the valve seat and the valve body 58. The first sealing ring 47 is usually made of wear-resistant and corrosion-resistant materials to ensure its long-term reliability and sealing performance. In addition to the first sealing ring 47, a second sealing ring 57 is also pressed between the first valve seat 48 and the valve core 53. This double sealing design further improves the sealing performance of the valve, ensuring that a good sealing effect can be maintained even under high-pressure water flow. The second sealing ring 57 also needs to be made of high-quality materials to cope with various harsh operating environments and water quality conditions. When it is necessary to control the on and off of the water flow, the driving motor 44 receives the signal and starts working, and its output shaft 45 drives the valve core 53 to rotate in the valve body 58. The rotation of the valve core 53 will change the relative position relationship between the first water hole 51 and the third water hole 63 and the siphon water outlet 54 and the flushing water outlet 50, thereby realizing the on and off control of the water flow. During the whole process, the pressure ring 55, the spring 46, the first sealing ring 47 and the second sealing ring 57 work together to provide stable support and sealing for the valve, ensuring the normal operation and long-term use of the valve.

The side wall of the second valve seat 25 is provided with a side hole 06 connected to the inner cavity of the water tank 12. The water sealing ring 22 is arranged on the inner wall of the second valve seat 25 and is located at the upper end of the flushing port 01. The water control component is located on the inner side of the second valve seat 25.

[0052] Specifically, Fig. 9As shown, the flushing valve 33 includes a second valve seat 25 and a valve cover 09. The second valve seat 25 is fastened to the bottom plate 24 of the water tank 12 by a nut 03 to ensure that the flushing valve 33 is firmly installed in the water tank 12. The flushing port 01 is arranged inside the second valve seat 25 and extends to the outside of the water tank 12 to discharge the water in the water tank 12 for flushing. The water suction port 11 is arranged on the side wall of the valve cover 09 and is connected to the second inlet end 41 of the impeller pump 34 for the impeller pump 34 provides a channel for absorbing water in the negative pressure chamber 20, so that a certain negative pressure is formed in the negative pressure chamber 20. The valve cover 09 is sealed and connected to the upper end of the second valve seat 25. A negative pressure chamber 20 is formed between the valve cover 09 and the second valve seat 25. This negative pressure chamber 20 is connected to the flushing port 01. A side hole 06 is provided on the side wall of the second valve seat 25. This side hole 06 is connected to the water tank 12 to ensure that the water in the water tank 12 can be flushed out from the flushing port 01 smoothly. The water sealing ring 22 It is arranged on the inner wall of the second valve seat 25, at the upper end of the flushing port 01. The function of the water sealing ring 22 is to cooperate with the water control component to control the sealing or conduction of the water path. The water control component is located on the inner side of the second valve seat 25, and can automatically or manually control the sealing or conduction of the water path at the water sealing ring 22. When the water control component is in a conducting state, water can flow out through the water sealing ring 22 and the flushing port 01 for large-volume flushing; when the water control component is in a sealed state, the water is sealed in the water tank 12 and will not flow out. The flushing valve 33 achieves precise control of the toilet flushing process through its unique structure and water control component. Whether it is normal flushing, manual flushing or replenishing flushing volume, it can ensure smooth and stable water flow, and at the same time ensure the sealing of each water outlet. The cooperation of the water sealing ring 22 and the water control component enables the flushing valve 33 to open and close the water path as needed, thereby achieving the effect of water saving and energy saving.

[0053] Furthermore, the water control component includes a valve stem 27, a return spring 10, a sealing gasket 21 and a U-shaped pressure plate 07. The pressure plate 07 is arranged around the valve stem 27, and the bottom of the pressure plate 07 is provided with a second water hole 05 connected to the negative pressure chamber 20 and the side hole 06. The sealing gasket 21 is arranged at the bottom of the pressure plate 07. The upper end of the valve stem 27 is slidably connected to the inner wall of the valve cover 09. The valve cover 09 is provided with an atmospheric hole 18 connected to the atmosphere. The return spring 10 is located in the negative pressure chamber 20. One end of the return spring 10 acts on the inner wall of the valve cover 09, and the other end acts on the top wall of the pressure plate 07. Under the joint action of atmospheric pressure, the pressure in the negative pressure chamber 20 and the return spring 10, the pressure plate 07 constitutes a water control component that automatically or manually controls the sealing or conduction of the water path at the water sealing ring 22.

[0054] Specifically, the water control component is mainly composed of a valve stem 27, a reset spring 10, a sealing gasket 21 and a U-shaped pressure plate 07. The pressure plate 07 is arranged on the circumference of the valve stem 27, and a second water hole 05 connected to the negative pressure chamber 20 and the side hole 06 is provided at the bottom thereof. The second water hole 05 allows water to flow from the water tank 12 into the negative pressure chamber 20 through the side hole 06. The aperture of the second water hole 05 is small. The sealing gasket 21 is arranged on the bottom of the pressure plate 07 to form a seal between the pressure plate 07 and the second valve seat 25 or the water sealing ring 22. The upper end of the valve stem 27 is in contact with the valve The inner wall of the cover 09 is slidably connected, allowing the valve stem 27 to move up and down inside the valve cover 09. The up and down movement of the valve stem 27 can control the sealing or conduction state between the pressure plate 07 and the water sealing ring 22. The valve cover 09 is provided with an atmospheric hole 18 connected to the atmosphere, which is used to balance the pressure in the negative pressure chamber 20 when necessary, so that the pressure plate 07 can move under the combined action of the atmospheric pressure, the pressure in the negative pressure chamber 20 and the reset spring 10. The reset spring 10 is located in the negative pressure chamber 20, one end of which acts on the inner wall of the valve cover 09, and the other end acts on the pressure plate. 07, the elastic force of the return spring 10 can ensure that after the flushing is completed, the pressure plate 07 can automatically reset and return to the position sealed with the water sealing ring 22. During normal flushing, the impeller pump 34 works to suck away the water in the negative pressure chamber 20, so that a certain vacuum degree is formed in the negative pressure chamber 20. The sum of the pressure in the negative pressure chamber 20, the elastic force of the return spring 10 and the atmospheric pressure is less than the water pressure on the bottom of the pressure plate 07. At this time, the pressure plate 0707 moves up and compresses the return spring 10. The water path at the water sealing ring 22 is connected, and the water in the water tank 12 is discharged through the side hole. 06 enters the flush port 01, the toilet starts to discharge sewage, and when the impeller pump 34 works, the pressure in the negative pressure chamber 20 drops to form a negative pressure, which helps to absorb water from the water tank 12 through the second water hole 05. After the sewage is discharged, the impeller pump 34 stops, and the water in the water tank 12 enters the negative pressure chamber 20 through the second water hole 05. The pressure in the negative pressure chamber 20 increases, and the sum of the pressure in the negative pressure chamber 20, the elastic force of the return spring 10 and the atmospheric pressure is greater than the water pressure on the bottom of the pressure plate 07. At this time, the pressure plate 07 moves down and presses the water channel at the water sealing ring 22 to seal.

[0055] Furthermore, a third sealing ring 19 is embedded in the side wall of the valve stem 27, a downward first extension tube 29 is provided on the inner top wall of the valve cover 09, the first extension tube 29 is slidably sleeved with the valve stem 27, the third sealing ring 19 is pressed between the first extension tube 29 and the valve stem 27, a fourth sealing ring 08 is pressed between the valve cover 09 and the second valve seat 25, a fifth sealing ring 23 is pressed between the second valve seat 25 and the bottom plate 24, an upward second extension tube 26 is provided on the top of the valve cover 09, the upper end of the second extension tube 26 is closed, the air hole 18 is opened at the top of the second extension tube 26, the upper end of the valve stem 27 is slidably sleeved in the second extension tube 26, a sixth sealing ring 16 is embedded in the top side wall of the valve stem 27, a water replenishment pipe 28 is provided on the side wall of the second extension tube 26 which is higher than the liquid level of the water tank 12, and the water replenishment port 13 is arranged on the water replenishment pipe 28, a water flow channel 02 connected to the water replenishment port 13 and the flushing port 01 is provided in the valve stem 27, and the water flow channel 02 is used to supplement the water output of the flushing port 01, the top of the valve stem 27 is closed, and a water flow groove 15 for connecting the water path between the water inlet and the water outlet flow channel 43 is provided on the inner wall of the valve stem 27, and a pull wire 17 that can manually move the valve stem 27 up and down is provided on the top of the valve stem 27, and the upper end of the pull wire 17 extends to the outside of the water tank 12 through the large air hole 18, and an upward exhaust port 14 is provided on the side wall of the water replenishment pipe 28, and the exhaust port 14 is connected to the float valve 32 in the toilet through a thin tube, and the float valve 32 is installed on the bottom plate 24 of the water tank 12, and the bottom plate 24 is provided with an assembly port 04 adapted to the float valve 32, and the float valve 32 is provided with a water inlet hole 30 and a water outlet hole 31, and the water outlet hole 31 is connected to the water tank 12.

[0056] Specifically, the third sealing ring 19 is embedded in the side wall of the valve stem 27 and is usually made of rubber or similar materials to ensure a good seal between the valve stem 27 and the first extension tube 29. The first extension tube 29 is a tubular structure extending downward from the inner top wall of the valve cover 09, and is slidably sleeved with the valve stem 27, which means that the valve stem 27 can move up and down inside the first extension tube 29 without generating excessive friction or leakage. When the valve stem 27 slides inside the first extension tube 29, the third sealing ring 19 is pressed between the first extension tube 29 and the valve stem 27. This pressing action forms a sealing interface to prevent water or other liquids from leaking from the gap between the valve stem 27 and the first extension tube 29. The design of the third sealing ring 19 and the first extension tube 29 ensures that the water control component can still maintain its sealing performance when the valve stem 27 moves up and down.

[0057] The fourth sealing ring 08 is located between the valve cover 09 and the second valve seat 25. When the valve cover 09 and the second valve seat 25 are connected by bolts or other fastening methods, the fourth sealing ring 08 is pressed between the two to form a sealing interface, which ensures that no leakage will occur at the connection between the valve cover 09 and the second valve seat 25. The fifth sealing ring 23 is located between the second valve seat 25 and the bottom plate 24. When the second valve seat 25 is installed on the bottom plate 24 of the water tank 12, the fifth sealing ring 23 is pressed between them to also form a sealing interface, which ensures that the water in the water tank 12 will not leak out from the gap between the second valve seat 25 and the bottom plate 24. By respectively arranging the fourth sealing ring 08 and the fifth sealing ring 23 between the valve cover 09 and the second valve seat 25 and between the second valve seat 25 and the bottom plate 24, the sealing performance of the toilet flushing system is greatly improved.

[0058] The second extension tube 26 is located at the top of the valve cover 09, extending upward and closing its upper end. This structure provides a sliding space for the valve stem 27. The air hole 18 is opened at the top of the second extension tube 26. The upper end of the valve stem 27 is slidably sleeved in the second extension tube 26, allowing the valve stem 27 to move up and down in the second extension tube 26. The third sealing ring 19 is embedded in the top side wall of the valve stem 27 and contacts the inner wall of the second extension tube 26. When the valve stem 27 slides in the second extension tube 26, the third sealing ring 1916 ensures that there will be no leakage between the two. The water supply pipe 28 is arranged on the side wall of the second extension tube 26, and its position is higher than the liquid level of the water tank 1212. The water supply port 13 of the water supply pipe 28 is connected to the water outlet end of the impeller pump 34, which is used to provide additional water to the system when needed.

[0059] The water flow channel 02 is located inside the valve stem 27 and is connected to the water supply port 13 and the flushing port 01. When the valve stem 27 is in a specific position (such as during flushing), the water flow channel 02 allows the water flowing in from the water supply pipe 28 to flow to the flushing port 01 through the valve stem 27, thereby replenishing the water output of the flushing port 01. During normal flushing, the impeller pump 34 works, and the water in the negative pressure chamber 20 is sucked away, forming a certain negative pressure. The pressure plate 07 drives the valve stem 27 to move upward, and the water path at the water sealing ring 22 between the side hole 06 and the flushing port 01 is opened. The water in the water tank 12 flows out through the water sealing ring 22 and the flushing port 01 for large-volume flushing. When the flushing volume needs to be supplemented, the water sucked away from the negative pressure chamber 20 by the impeller pump 34 passes through the water supply pipe 28. It is sent into the water flow channel 02 in the valve stem 27, and then flows to the flushing port 01, thereby increasing the total water volume of the flushing. After the flushing is completed, the impeller pump 34 stops, the reset spring 10 pushes the pressure plate 07 to reset, and the water sealing ring 22 is re-sealed to prevent water from continuing to flow out. By setting the water supply pipe 28 and the water flow channel 02, the toilet flushing system can provide additional water when needed, thereby improving the siphon effect of the sewage inside the toilet. The design of the sixth sealing ring 16 and the valve stem 27 ensures the sealing between the water supply pipe 28 and the water flow channel 02, and prevents water leakage. The design of the second extension tube 26 and the large air hole 1836 allows the internal pressure of the system to be balanced when needed, ensuring the smooth movement of the valve stem 27 and the pressure plate 07.

[0060] The top of the valve stem 27 is designed to be closed, which means that water will not flow in or out directly from the top of the valve stem 27. The water groove 15 is located on the inner wall of the valve stem 27 and extends downward for a section. The water groove 15 is used to connect the water path between the water replenishment port 13 and the water flow channel 02. When the impeller pump 34 is working, water flows in from the water replenishment port 13, passes through the water groove 15, and then flows to the water flow channel 02, and finally reaches the flushing port 01. The water replenishment port 13 is located at the second extension tube 2 6 side wall, and is higher than the liquid level of the water tank 12, and is connected to the water outlet end of the impeller pump 34, so that the water in the water tank 12 can be prevented from entering the water supply pipe 28, and then flowing to the flushing port 01 to cause the toilet to leak. The water flow channel 02 is located inside the valve stem 27, one end of which is connected to the water supply port 13 through the water groove 15, and the other end is connected to the flushing port 01. The impeller pump 34 starts to work, pumping water from the water supply port 13, and the water flows through the water groove 15 into the water flow channel in the valve stem 27. Channel 02, water eventually flows to flush port 01 through water flow channel 02, and flushes together with the water in water tank 12. Since the top of valve stem 27 is closed, and the sixth sealing ring 16 is embedded between the top side wall of valve stem 27 and the inner wall of second extension tube 26, the sealing between valve stem 27 and second extension tube 26 is ensured, and water leakage is prevented. By setting water channel 15, water connection between water replenishment port 13 and water flow channel 02 is realized, so that the system can provide additional flushing volume when needed. The design of closed top of valve stem 27 and sixth sealing ring 16 ensures the sealing of system and prevents water leakage. The design of valve stem 27 takes sealing and functionality into consideration. Water connection between water replenishment port 13 and water flow channel 02 is realized through water channel 15, providing the system with the ability to supplement flushing volume. At the same time, closed top of valve stem 27 and sixth sealing ring 16 ensures the sealing of system and prevents water leakage.

[0061] The pull wire 17 is located at the top of the valve stem 27 and is connected to the valve stem 27. The pull wire 17 is used to manually control the up and down movement of the valve stem 27. The user can pull the pull wire 17 outside the water tank 12 to make the valve stem 27 move up and down inside the water tank 12, thereby controlling the flushing process. The large air hole 18 is located at the upper end of the pull wire 17, passing through the wall of the water tank 12 to extend the pull wire 17 to the outside of the water tank 12. The large air hole 18 ensures that the pull wire 17 will not be obstructed by water when passing through the wall of the water tank 12, while allowing air to pass through to prevent negative pressure from being generated inside the water tank 12. When a power outage occurs, the leaf When the wheel pump 34 cannot work and the user needs to flush, the user can pull the pull wire 17 outside the water tank 12 to move the valve stem 27 upward. The upward movement of the valve stem 27 will open the water path at the water sealing ring 22, allowing the water in the water tank 12 to flow out through the flushing port 01 for drainage. After the drainage is completed, the user can loosen the pull wire 17, and the reset spring 10 will push the valve stem 27 to move downward, so that the water sealing ring 22 is re-closed to prevent water from continuing to flow out. By setting the pull wire 17 and the large air hole 18, the user can conveniently control the up and down movement of the valve stem 27 outside the water tank 12.

[0062] Specifically, an upward exhaust port 14 is provided on the side wall of the water supply pipe 28. The main function of the exhaust port 14 is to allow air to enter the water supply pipe 28, thereby preventing negative pressure or vacuum from being generated during the water pumping or water supply process, and ensuring smooth water flow. The exhaust port 14 is connected to the float valve 32 in the toilet through a thin tube. When water enters the water supply pipe 28, water can be prevented from flowing out of the toilet from the exhaust port 14.

[0063] like Figure 1 and Figure 5As shown, the float valve 32 is installed on the bottom plate 24 of the water tank 12, and the bottom plate 24 is provided with an assembly port 04 adapted to the float valve 32 to ensure that the float valve 32 can be firmly installed on the bottom plate 24. The float valve 32 is provided with a water inlet hole 30, and the float valve 32 is also provided with a water outlet hole 31, which is connected to the inner cavity of the water tank 12. Under normal circumstances, the water outlet hole 31 is in a closed state, but when the water level in the water tank 12 drops to a certain level, the float valve 32 will automatically open the water outlet hole 31 to replenish water. When the water level in the water tank 12 is normal, the float (or floating ball) of the float valve 32 rises due to the buoyancy, so that the water outlet hole 31 is closed. When the water level in the water tank 12 drops (such as When the water level in the water tank 12 changes (caused by flushing), the buoyancy of the float decreases, and the water outlet 31 of the float valve 32 automatically opens until the water level rises to a normal level again. Before installing the float valve 32, it should be ensured that the assembly port 04 on the bottom plate 24 is fully compatible with the size and shape of the float valve 32 to ensure the stability and sealing of the installation. After the installation is completed, the float valve 32 should be tested to ensure that it can work normally and automatically open and close the water outlet 31 when the water level in the water tank 12 changes. The size of the float valve 32 (such as the diameter of the float, the diameter of the valve, etc.) should be selected and calculated according to the design of the water tank 12 and the performance of the impeller pump 34 to ensure that it can effectively control the water level in the water tank 12.

[0064] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
