[0002] Existing smart toilets typically use a water pump to pump water from a water tank to the toilet's flushing circuit, thereby achieving the flushing function. The water pump requires electricity to operate. To prevent the pump from losing power during a municipal power outage and preventing flushing, it is generally equipped with a battery or backup power supply. Users need to replace the backup battery after a period of use, which is troublesome and easy to forget, resulting in a failure to flush during a power outage. Furthermore, the internal switching of the flush and down flush functions uses electrically controlled valves such as solenoid valves and electronic switching valves.

DETAILED DESCRIPTION

[0041] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0042] The present invention relates to a flushing system, comprising a water inlet assembly 100 , a switching assembly 300 , a control valve 200 , a water pump 600 , a manual valve 500 , a first floating mechanism 700 , a second floating mechanism 800 and a Venturi pipe 940 .

[0043] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8and Figure 10 As shown, the water inlet assembly 100 includes a first waterway 110, a second waterway 120 and a third waterway 130. The first waterway 110, the second waterway 120 and the third waterway 130 can all be formed by shells or pipes. In this embodiment, Figure 5As shown, the first waterway 110 is formed by a plurality of pipes connected in a T-shape. The water inlet of the first waterway 110 is opened at the bottom, and the external water flows from bottom to top after entering the first waterway 110. The third waterway 130 is composed of a pipe arranged outside the first waterway 110, and the water outlet side of the first waterway 110 is connected to the water inlet side of the third waterway 130. The water outlet is opened at the lower part of the third waterway 130, and the upper part of the third waterway 130 can be connected to the upper part of the first waterway 110. The second waterway 120 is connected to the third waterway 130. The switching assembly 300 includes a fourth waterway 310, a fifth waterway 320, a switching valve 400 and an elastic valve 330. The switching assembly 300 can be composed of a plurality of shells or pipe fittings, and the fourth waterway 310 and the fifth waterway 320 are formed inside the shells or pipe fittings. Depending on the direction of water flow, one end of the fourth water channel 310 and the water inlet of the fifth water channel 320 can be connected to each other. A switching valve 400 is installed between the water outlet of the fourth water channel 310 and the water inlet of the fifth water channel 320. The switching valve 400 controls whether the water inlet of the fourth water channel 310 is connected to the water inlet of the fifth water channel 320. Before the elastic valve 330 is installed, the water outlet of the fourth water channel 310 and the water outlet of the fifth water channel 320 are connected to each other. After the elastic valve 330 is installed between the water outlet of the fourth water channel 310 and the water outlet of the fifth water channel 320, the water outlet of the fourth water channel 310 and the water outlet of the fifth water channel 320 are no longer connected to each other. One side of the elastic valve 330 is subject to water pressure from the outlet of the fourth water channel 310, and the other side is subject to water pressure from the outlet of the fifth water channel 320. The elastic valve 330 moves between the outlets of the fourth water channel 310 and the outlets of the fifth water channel 320 based on the water pressure differential between the two sides and its own elastic force. Under the action of its own elastic force, the elastic valve 330 tends to move toward blocking the outlet of the fourth water channel 310. When there is no water at either the outlet of the fourth water channel 310 or the outlet of the fifth water channel 320, the elastic valve 330 moves to and remains in a position that blocks the outlet of the fourth water channel 310. The first water channel 110 can be connected to the inlet of the fourth water channel 310 via a pipe. The control valve 200 is mounted on the water inlet assembly 100 and is used to control the opening and closing of the first water channel 110. The outlet of the water pump 600 is connected to the inlet of the fourth water channel 310 via a water pipe. The manual valve 500 is mounted on the water inlet assembly 100 and is manually operated to control the flow of water between the first waterway 110 and the fourth waterway 310. The first floating mechanism 700 includes a first container 710 and a first float 720. The first container 710 can be configured as a box-shaped, cylindrical, or other water-holding container. The first container 710 can communicate with the outside. The first float 720 can be a floating block or other structure. The first float 720 is placed in the first container 710 and rises and falls with the water level in the first container 710.The first float 720 is connected to the control valve 200, and the control valve 200 is opened or closed by changing the height of the first float 720. The second floating mechanism 800 includes a second container 810 and a second float 820. The second container 810 can be a box-shaped, cylindrical, or other water-holding container. The second container 810 can communicate with the outside. The second float 820 can be a floating block or other structure. The second float 820 is placed in the second container 810 and rises and falls with the water level in the second container 810. The second float 820 is connected to the switching valve 400, and the switching valve 400 is opened or closed by changing the height of the second float 820. The second waterway 120 can be a water pipe, connected between the second container 810 and the third waterway 130. The Venturi pipe 940 is connected to the outlet of the fourth waterway 310 via a pipe. Figure 13 As shown, the venturi pipe 940 includes a water inlet section 941, a constricted section 942, a throat section 943, a flared section 944 and a suction section 945. The water inlet section 941, the constricted section 942, the throat section 943 and the flared section 944 are connected in sequence. The inner diameter of the constricted section 942 gradually decreases from the water inlet section 941 to the throat section 943. The inner diameter of the throat section 943 is smaller than the inner diameter of the water inlet section 941. The inner diameter of the flared section 944 gradually increases in a direction away from the throat section 943. The suction section 945 is connected to the flared section 944 along the radial direction of the flared section 944, and the venturi pipe 940 directly sucks the external liquid into the flared section 944 through the suction section 945.

[0044] In actual use, the flushing system is mainly used on toilets, but can also be used on other sanitary ware and other products that require flushing. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the flushing system of the present invention is applied to a toilet, which also includes a toilet body 900 and a water tank 910. The toilet body 900 has a brush ring water channel 920 and a bottom spray water channel 930. The brush ring water channel 920 flushes the toilet cavity 901 of the toilet body 900 from top to bottom, while the bottom spray water channel 930 flushes the bottom sewage outlet 902 of the toilet body 900. The flushing system is installed on the water tank 910. The water pump 600 can be located outside or inside the water tank 910, and the other components of the flushing system are located in the water tank 910. The venturi pipe 940 is connected to the brush ring water channel 920 of the toilet body 900 by a water pipe, and the water outlet side of the fifth water channel 320 is connected to the bottom spray water channel 930 of the toilet body 900 by a water pipe. The water inlet of the water pump 600 is connected to the water tank 910, and the venturi pipe 940 is located at the bottom of the water tank 910. The working principle of the flushing system will be described below by applying the flushing system to a toilet.

[0045] The flushing system is mainly divided into two working modes, one is power-on mode and the other is power-off mode.

[0046] In the initial state, the water in the water tank 910 is filled to the operating level. At this point, the first and second containers 710, 810 are immersed in the water in the water tank 910, and the first and second floats 720, 820 are floating upward due to buoyancy. The control valve 200 remains in a closed position when the first float 720 is floating upward, thus shutting off the first waterway 110. The switching valve 400 remains in a closed position when the second float 820 is floating upward, isolating the inlet side of the fourth waterway 310 from the inlet side of the fifth waterway 320. Both manual valves 500 are closed, effectively shutting off the flow of water between the first and fourth waterways 110, 310. The water pump 600 is also off. The inlet of the first waterway 110 is connected to the municipal water supply (tap water pipe).

[0047] In the power-on mode, the external power supply system provides power to the water pump 600. When the toilet body 900 needs to be flushed, the water pump 600 is turned on. The water pump 600 draws water from the water tank 910 and pumps the water to the water inlet side of the fourth waterway 310, and then flows along the fourth waterway 310. Since the switching valve 400 is in the closed state at this time, the water will not flow into the fifth waterway 320. Figure 9 As shown, under the action of the water pressure in the fourth waterway 310, the elastic valve 330 moves, opening the outlet of the fourth waterway 310. The elastic valve 330 then moves to the outlet of the fifth waterway 320, thereby blocking the outlet of the fifth waterway 320. Water from the outlet of the fourth waterway 310 is discharged through the Venturi pipe 940 into the brush ring waterway 920 of the toilet body 900, flushing the inner cavity of the toilet body 900. The water flowing through the Venturi pipe 940 creates a Venturi effect, drawing water from the water tank 910 into the Venturi pipe 940 through the suction section 945 and delivering it to the brush ring waterway 920. As the brushing ring uses water, the water in the water tank 910 gradually decreases, and the water in the second container 810 is discharged into the water tank 910. The water level in the second container 810 also gradually decreases, and the second float 820 also decreases accordingly. After the second float 820 drops, the second float 820 drives the switching valve 400 to switch to the open state. The water pump 600 keeps pumping water. Figure 8As shown, after the switching valve 400 is opened, the inlet side of the fourth water channel 310 and the inlet side of the fifth water channel 320 are connected. Water flows from the fourth water channel 310 into the fifth water channel 320 and toward the outlet side of the fifth water channel 320. Under the water pressure at the outlet side of the fifth water channel 320 and its own elastic force, the elastic valve 330 moves, blocking the outlet side of the fourth water channel 310 and opening the outlet side of the fifth water channel 320. Water flows from the outlet end of the fifth water channel 320 into the bottom spray channel 930 of the toilet body 900, flushing the bottom sewage outlet 902 of the toilet body 900. At this time, the flushing of the brush ring water channel 920 stops. As the water level in the second container 810 drops, the water in the first container 710 is discharged into the water tank 910, also lowering the water level and causing the first float 720 to descend. The first float 720 descends, causing the control valve 200 to switch to the open state. Now, water flows through the first waterway 110, supplying tap water to the third waterway 130 via the first waterway 110. Water replenishes the water tank 910 via the third waterway 130. Simultaneously, water replenishes the second container 810 via the third waterway 130 and the second waterway 120. The rate of water replenishment into the second container 810 is greater than the rate of water discharge from the second container 810 into the water tank 910. As the water level in the second container 810 rises, the second float 820 rises, causing the switching valve 400 to switch to the closed state, shutting off the connection between the fourth waterway 310 and the fifth waterway 320. This stops the water supply to the bottom spray waterway 930, and the bottom spray flushing stops. At this time, water flows back to the outlet side of the fourth waterway 310. Under the action of the water pressure of the fourth waterway 310 (there is no water pressure in the fifth waterway 320), the elastic valve 330 moves again to open the outlet side of the fourth waterway 310 and block the outlet side of the fifth waterway 320. Water is supplied to the brush ring waterway 920, and the toilet chamber 901 is flushed with the brush ring for the second time. At the same time, the bottom sewage outlet 902 of the toilet chamber 901 is sealed and replenished with water. The working time of the water pump 600 is set. After the water seal replenishment is completed within the preset time, the water pump 600 stops working and stops supplying water to the brush ring waterway 920. Water replenishes the water tank 910 through the first waterway 110 and the third waterway 130 until the water in the water tank 910 is replenished to the working water level. The first float 720 rises, driving the control valve 200 to close, shutting off the water supply to the first waterway 110. At this time, the flushing system enters standby mode. With the above working method, the flushing system can complete the work process of brushing the ring, bottom spray flushing, secondary brushing the ring, and water seal replenishment in the power-on mode.

[0048] In the power outage mode, the external power supply system cannot supply power to the water pump 600, and the water pump 600 cannot start pumping water. The flushing system is in the above-mentioned initial state. When the toilet needs to be flushed, the user manually opens the manual valve 500. Figure 6As shown, after the manual valve 500 is opened, the first waterway 110 and the fourth waterway 310 are connected. Tap water is supplied to the fourth waterway 310 through the first waterway 110, and the water flows into the water inlet side of the fourth waterway 310. At this time, the switching valve 400 is in a closed state, and water will not flow into the fifth waterway 320. Figure 9 As shown, the elastic valve 330 moves under the action of the water pressure of the fourth waterway 310, opens the outlet side of the fourth waterway 310, and moves to the outlet side of the fifth waterway 320 to block the outlet side of the fifth waterway 320. Water is discharged from the outlet side of the fourth waterway 310 through the Venturi pipe 940 to the brush ring waterway 920 of the toilet body 900 for brush ring flushing. When water passes through the Venturi pipe 940, a Venturi effect is generated, and the water in the water tank 910 is sucked into the Venturi pipe 940 through the suction section 945. As the brush ring uses water, the water in the water tank 910 gradually drops, and the water in the second container 810 is discharged into the water tank 910. The water level in the second container 810 also gradually drops, and the second float 820 also drops. After the second float 820 drops, the second float 820 drives the switching valve 400 to switch to the open state. The manual valve 500 remains in the open state, as shown Figure 8As shown, after the switching valve 400 is opened, the inlet side of the fourth water channel 310 and the inlet side of the fifth water channel 320 are connected. Water flows from the fourth water channel 310 into the fifth water channel 320 and toward the outlet side of the fifth water channel 320. Under the water pressure at the outlet side of the fifth water channel 320 and its own elastic force, the elastic valve 330 moves, blocking the outlet side of the fourth water channel 310 and opening the outlet side of the fifth water channel 320. Water flows from the outlet end of the fifth water channel 320 into the bottom spray channel 930 of the toilet body 900, flushing the bottom sewage outlet 902 of the toilet body 900. At this time, the flushing of the brush ring water channel 920 stops. As the water level in the second container 810 drops, the water in the first container 710 is discharged into the water tank 910, also lowering the water level and causing the first float 720 to drop. The drop of the first float 720 causes the control valve 200 to switch to the open state. At this point, the first waterway 110 is flowing, with tap water supplied through the first waterway 110 and the third waterway 130. Water is replenished in the water tank 910 through the third waterway 130, and water is simultaneously replenished in the second container 810 through the third waterway 130 and the second waterway 120. The rate of water replenishment in the second container 810 is greater than the rate of water discharge from the second container 810 into the water tank 910. The water level in the second container 810 rises, and the second float 820 rises, driving the switching valve 400 to switch to a closed state, shutting off the connection between the fourth waterway 310 and the fifth waterway 320, ceasing water supply to the bottom spray waterway 930, and halting bottom spray flushing. Water now flows back to the outlet of the fourth waterway 310. Under the influence of the water pressure in the fourth waterway 310 (there is no water pressure in the fifth waterway 320), the elastic valve 330 moves again, opening the outlet of the fourth waterway 310 and blocking the outlet of the fifth waterway 320. Water is supplied to the brush ring water channel 920, and the toilet chamber 901 is brushed for the second time, while the bottom sewage outlet 902 of the toilet chamber 901 is water-sealed and replenished. After the water seal replenishment is completed, the manual valve 500 is manually closed, and the first water channel 110 stops supplying water to the fourth water channel 310, that is, stops supplying water to the brush ring water channel 920. Water replenishes the water tank 910 through the first water channel 110 and the third water channel 130 until the water in the water tank 910 is replenished to the working water level. The first float 720 rises and drives the control valve 200 to close, shutting off the water supply to the first water channel 110. At this time, the flushing system enters the standby state. With the above working method, the flushing system completes the work process of brushing the ring, bottom spray flushing, secondary brushing the ring, and water seal replenishment in the power outage mode.

[0049] In one embodiment, Figure 8 and Figure 9As shown, the fourth waterway 310 includes a fourth water inlet channel 311 and a fourth water outlet channel 312. The fourth water inlet channel 311 serves as the water inlet side of the fourth waterway 310, and the fourth water outlet channel 312 serves as the water outlet side of the fourth waterway 310. The fourth water outlet channel 312 can be arranged around the downstream section of the fourth water inlet channel 311. In the direction of water flow, the downstream end of the fourth water inlet channel 311 is the fourth water inlet branch 313, and the upstream end of the fourth water outlet channel 312 is the fourth water outlet branch 314. The fourth water outlet branch 314 is arranged around the fourth water inlet branch 313, and the fourth water outlet branch 314 and the fourth water inlet branch 313 can be flush. The first waterway 110 can be connected to the fourth water inlet channel 311 via a pipe. The water outlet of the water pump 600 is connected to the fourth water inlet channel 311 via a water pipe. The fifth waterway 320 includes a fifth water inlet channel 321 and a fifth outlet channel 322. The fifth water outlet channel 322 can be arranged around the downstream section of the fifth water inlet channel 321. The fifth water inlet channel 321 serves as the water inlet side (upstream section) of the fifth waterway 320, and the fifth water outlet channel 322 serves as the water outlet side (downstream section) of the fifth waterway 320. The fifth water outlet channel 322 is connected to the bottom spray water channel 930 through a water pipe. The downstream end of the fifth water inlet channel 321 is the fifth water inlet branch 323, and the upstream end of the fifth outlet channel 322 is the fifth water outlet branch 324. The fifth water inlet branch 323 is arranged around the fifth water outlet branch 324, and the fifth water inlet branch 323 and the fifth water outlet branch 324 can be arranged to be axially staggered. The fourth water outlet branch 314 is opposite to the fifth water inlet branch 323, and the fourth outlet branch 314 and the fifth water inlet branch 323 can be connected. The fourth water inlet branch 313 and the fifth water outlet branch 324 are positioned opposite each other, with a certain distance between them. The elastic valve 330 is movably mounted between the fourth water outlet branch 314 and the fifth water inlet branch 323. The inner diameters of the fourth water outlet branch 314, the inner diameters of the fifth water inlet branch 323, and the outer diameter of the elastic valve 330 can be set to be the same. The switching valve 400 is mounted between the fourth water inlet channel 311 and the fifth water inlet channel 321. Specifically, the elastic valve 330 includes a first valve flap 331 and a first elastic member 332. The first valve flap 331 has a first sealing side 333 and a second sealing side 334 on either side. The first valve flap 331 is movably mounted between the fourth water outlet branch 314 and the fifth water inlet branch 323. The first sealing side 333 faces the fourth water inlet branch 313, and the second sealing side 334 faces the fifth water outlet branch 324. The elastic member can be an elastic component such as a spring. The first elastic member 332 may have one end abutting against the second closed side 334 and the other end abutting against the fifth water inlet channel 321 . The first elastic member 332 applies an elastic force on the first valve flap 331 to move the first valve flap 331 toward the fourth water inlet outlet 313 .Under the elastic force of the first elastic member 332, the first valve flap 331's first sealing side 333 abuts against the fourth water inlet outlet 313, sealing the fourth water inlet outlet 313. The second sealing side 334 moves away from the fifth water outlet 324, defining the position of the first valve flap 331 at this point as the first position. When the first valve flap 331 moves until the first sealing side 333 moves away from the fourth water inlet outlet 313, the second sealing side 334 abuts against and seals the fifth water outlet 324, defining the position of the first valve flap 331 at this point as the second position. In the aforementioned power-on or power-off mode, when water flows into the fourth water inlet channel 311, the switching valve 400 is closed, and the fifth waterway 320 is dehydrated. Water pressure in the fourth water inlet channel 311 acts on the first closed side 333. This pressure overcomes the elastic force of the first elastic member 332, pushing the first valve flap 331 from the first position to the second position. Water then flows from the fourth water inlet channel 311 through the fourth water inlet branch 313 and the fourth water outlet branch 314 into the fourth water outlet channel 312, and is then delivered to the brush ring waterway 920. When the switching valve 400 is opened, the fourth water inlet channel 311 connects with the fifth water inlet channel 321. Water flows from the fourth water inlet channel 311 into the fifth water inlet channel 321. The water pressure in the fifth water inlet channel 321 acts on the second closed side 334, and in combination with the elastic force of the first elastic member 332, pushes the first valve flap 331 from the second position to the first position. Water in the fifth water inlet channel 321 flows through the fifth water inlet branch 323 and the fifth water outlet branch 324 into the fifth outlet channel 322, and is then delivered to the bottom spray waterway 930. When the switching valve 400 is closed again, the fourth water inlet channel 311 and the fifth water inlet channel 321 are disconnected, and the first valve flap 331 moves again to the second position under the water pressure of the fourth water inlet channel 311. After the water supply to the fourth water inlet channel 311 is stopped, the first valve flap 331 returns to the first position under the elastic force of the first elastic member 332. This achieves the state switching between the fourth water channel 310 and the fifth water channel 320, and further realizes the switching between the brush ring and bottom spray flushing.

[0050] Based on the above embodiment, a fourth water inlet 340 is defined between the fourth water inlet channel 311 and the fifth water inlet channel 321. The fourth water inlet 340 is formed at one end of the fourth water inlet channel 311, and the water inlet section 941 of the fifth water inlet channel 321 can be disposed around one end of the fourth water inlet 340. A water pump is connected to the fourth water inlet channel 311 via a water pipe. The switching valve 400 includes a first valve cover 410, a second valve flap 420, a first rocker arm 430, and a first pressure pad 440. The second valve flap 420 is elastically mounted on the first valve cover 410. The second valve flap 420 can be configured as an elastic valve 330 membrane structure that is inherently elastically deformable. A first pressure chamber 450 is defined between the second valve flap 420 and the first valve cover 410. A first pressure relief hole 411 is formed in the first valve cover 410, communicating with the first pressure chamber 450. One end of the first swing arm 430 is swingably connected to the first valve cover 410 via a rotating shaft, and the other end is swingably connected to the second float 820 via a rotating shaft. A first pressure pad 440 is mounted on the first swing arm 430. The first pressure pad 440 may be a rubber pad, a silicone pad, or the like. When the second float 820 is raised or lowered, the first swing arm 430 moves. The first swing arm 430 swings relative to the second float 820, driving the first pressure pad 440 to block or move away from the first pressure relief hole 411. When the second float 820 rises, the first swing arm 430 drives the first pressure pad 440 to block the first pressure relief hole 411. At this point, the first pressure chamber 450 is in a closed, pressure-holding state. The second valve flap 420, through its own elastic action, simultaneously abuts against the fourth water outlet 340, blocking it. The water pressure in the fourth water inlet channel 311 acts on the side of the second valve flap 420 away from the first pressure chamber 450. Due to the pressure-holding effect of the first pressure chamber 450, the second valve flap 420 is able to maintain its seal against the fourth water outlet 340. When the second float 820 descends, the first swing arm 430 swings relative to the first valve cover 410, driving the first pressure pad 440 away from the first pressure relief hole 411. The pressure in the first pressure chamber 450 is relieved, and the water pressure in the fourth water inlet channel 311 acts on the second valve flap 420, causing it to elastically deform and move away from the fourth water outlet 340. The fourth water outlet 340 opens, connecting the fourth water inlet channel 311 and the fifth water inlet channel 321 through the fourth water outlet 340. When there is no water pressure or the water pressure in the fourth water inlet channel 311 is reduced, the second valve flap 420 elastically returns to abut against the fourth water outlet 340 again to block the fourth water outlet 340 .

[0051] Based on the above embodiments, Figure 4 、 Figure 10 、 Figure 11 and Figure 12As shown, the first container 710 and the second container 810 can be formed by an integrally formed box body separated by a partition. Alternatively, the first container 710 and the second container 810 can be two independent components. A first drain hole 711 is provided at the bottom of the first container 710, through which water in the first container 710 can flow into the water tank 910. A third float 730 is mounted on the first drain hole 711. The shape of the third float 730 is adapted to the first drain hole 711, and the third float 730 can be raised and lowered in the first drain hole 711. The sidewall of the third float 730 can be hollowed out. A second drain hole 811 is provided at the bottom of the second container 810, through which water in the second container 810 can flow into the water tank 910. A fourth float 830 is mounted on the second drain hole 811. Its shape matches that of the second drain hole 811, allowing it to rise and fall within the second drain hole 811. The fourth float 830 can be configured with a hollowed-out sidewall. Initially, the water level in the water tank 910 overflows the first container 710 and the second container 810. At this point, the third and fourth floats 730, 830, rise under the buoyancy of the water in the water tank 910. The third float 730 rises until it blocks the first drain hole 711, and the fourth float 830 rises until it blocks the second drain hole 811. When the water level in the water tank 910 drops below the bottoms of the first and second containers 710, 810, the third float 730 descends relative to the first drain hole 711 as the water level in the water tank 910 drops. The first drain hole 711 opens, allowing the water in the first container 710 to drain into the water tank 910 through the hollowed-out portion of the sidewall of the third float 730. As the water level in the water tank 910 drops, the fourth float 830 descends relative to the second drain hole 811. The second drain hole 811 opens, allowing the water in the second container 810 to drain into the water tank 910 through the hollowed-out portion of the sidewall of the fourth float 830. After the water in the first and second containers 710, 810, is drained into the water tank 910, the first and second floats 720, 820 descend, respectively switching the control valve 200 and the switching valve 400. When the second water channel 120 replenishes water to the second container 810, the replenishment rate is greater than the drainage rate of the second container 810 into the water tank 910. This allows the second float 820 to rise and switch the switching valve 400 before the water level in the water tank 910 reaches a level higher than the second drain hole 811. Once the water in the water tank 910 is replenished, the third and fourth floats 730 and 830, under the buoyancy of the floats, re-block the first and second drain holes 711 and 811.

[0052] Further, such as Figure 12As shown, the bottom of the second container 810 is also provided with a third drainage hole 812. A rotating member 840 is mounted on the third drainage hole 812. The rotating member 840 can be configured as a plate, etc., and is capable of rotating relative to the third drainage hole 812. When the rotating member 840 rotates, it can change the relative coverage area with the third drainage hole 812, thereby changing the water flow area of ​​the third drainage hole 812. By controlling the water flow area of ​​the third drainage hole 812 by the rotating member 840, it is possible to control the difference between the speed at which the second water channel 120 replenishes the second container 810 and the total drainage speed of the second drainage hole 811 and the second drainage hole 811, thereby controlling the flushing time of the bottom spray water channel 930.

[0053] In one embodiment, Figure 5As shown, the first water channel 110 includes a first water inlet channel 111 and a first water outlet channel 112. The first water inlet channel 111 can be formed by a T-shaped pipe, and the first water outlet channel 112 is located at the upper part of the first water inlet channel 111. A pipe can be placed on the upper part of the first water inlet channel 111 with a gap between the two, and the gap constitutes the first water outlet channel 112. The bottom opening of the first water inlet channel 111 serves as the water inlet end and is connected to the external tap water pipe. The third water channel 130 is connected to the first water outlet channel 112. It can be that a straight pipe is placed on the lower part of the first water inlet channel 111, and the gap between the straight pipe and the outer wall of the first water inlet channel 111 forms the third water channel 130. The upper end of the third water channel 130 is connected to the lower part of the first water outlet channel 112. The lower part of the third water channel 130 is open, so that the third water channel 130 is connected to the water tank 910. A first water inlet 113 is defined between the first water inlet channel 111 and the first water outlet 112. The first water inlet 113 can be one end of a T-shaped pipe above the first water inlet channel 111. The structure of the control valve 200 can be similar to that of the switching valve 400 described above. The control valve 200 includes a second valve cover 210, a third valve flap 220, a second rocker arm 230, and a second pressure pad 240. The third valve flap 220 is elastically mounted on the second valve cover 210 and can be formed from a self-elastically deformable rubber valve membrane. A second pressure chamber 250 is defined between the third valve flap 220 and the second valve cover 210. A second pressure relief hole 211 is formed in the second valve cover 210, communicating with the second pressure chamber 250. One end of the second rocker arm 230 can be rotatably mounted on the first float 720 via a rotating shaft, while the other end can be rotatably mounted on the second valve cover 210 via a rotating shaft. The second pressure pad 240 is installed on the second rocker arm 230. The second pressure pad 240 can be a rubber pad or other component. When the first float 720 rises, it drives the second rocker arm 230 to move, and the second rocker arm 230 drives the second pressure pad 240 to abut against the second pressure relief hole 211, blocking the second pressure relief hole 211. At this time, the second pressure chamber 250 is a closed cavity to form a pressure-blocking. The third valve flap 220 abuts against the first water outlet 113, blocking the first water outlet 113. The water in the first water inlet channel 111 cannot be supplied to the first water outlet channel 112. When the first float 720 descends, the second pressure pad 240 is separated from the second pressure relief hole 211 by the second rocker arm 230, the second pressure chamber 250 is depressurized, and the third valve flap 220 is elastically deformed under the water pressure of the first water inlet channel 111 and leaves the first water outlet 113. The water in the first water inlet channel 111 is transported to the first water outlet channel 112 through the first water outlet 113 , and then transported to the third water channel 130 to replenish the water tank 910 .

[0054] In one embodiment, Figure 4 、 Figure 5 and Figure 6As shown, the first waterway 110 and the fourth waterway 310 are connected via the sixth waterway 140. The sixth waterway 140 includes a sixth water inlet channel 141 and a sixth water outlet channel 142. The sixth water inlet channel 141 is connected to the first waterway 110 located upstream of the control valve 200, that is, the sixth water inlet channel 141 is connected to the first water inlet channel 111. Water in the first water inlet channel 111 can be directly transported to the sixth water inlet channel 141. The sixth outlet channel 142 is connected to the fourth water inlet channel 311 of the fourth waterway 310. A sixth water outlet 143 is defined between the sixth water inlet channel 141 and the sixth outlet channel 142. A manual valve 500 controls the opening and closing of the sixth water outlet 143. The manual valve 500 can be a mechanical valve that is manually opened and closed, such as an angle valve or a ball valve. When the sixth water outlet 143 is blocked by the manual valve 500, water cannot be transported from the sixth water inlet channel 141 to the sixth outlet channel 142. When the manual valve 500 is opened, the sixth water outlet 143 is opened, and water is transported to the fourth water channel 310 along the first water inlet channel 111 , the sixth water inlet channel 141 , and the sixth water outlet channel 142 .

[0055] Specifically, such as Figure 4 、 Figure 5 and Figure 6As shown, the manual valve 500 includes a pull rope 510, a valve seat 520, a third rocker arm 530, a fourth valve flap 540, a piston 550, and a second elastic member 560. The third rocker arm 530 is rotatably mounted on the valve seat 520 via a rotating shaft. The pull rope 510 is connected to the third rocker arm 530. The pull rope 510 can be a steel wire rope, for example. The fourth valve flap 540 is elastically mounted on the valve seat 520. The fourth valve flap 540 can be an elastically deformable valve membrane structure. In its natural state, the fourth valve flap 540 blocks the sixth water outlet 143. A third pressure chamber 570 is defined between the fourth valve flap 540 and the valve seat 520. The valve seat 520 defines a valve chamber 521 that communicates with the third pressure chamber 570. The piston 550 is movably mounted in the valve chamber 521, with the circumferential sidewalls of the piston 550 abutting against the valve chamber 521. A sealed space is formed between the valve chamber 521 and the third pressure chamber 570. The piston member 550 can move relative to the valve chamber 521. The second elastic member 560 can be an elastic component such as a spring. The second elastic member 560 applies an elastic force to the piston member 550 to move it toward the third pressure chamber 570. When the piston member 550 moves toward the third pressure chamber 570, the volume of the space formed by the third pressure chamber 570 and the valve chamber 521 decreases, so that the air pressure in the third pressure chamber 570 increases, pushing the fourth valve flap 540 to abut and seal on the sixth water outlet 143. When the pull cord 510 is pulled, it drives the piston 550 via the third rocker 530, moving it away from the third pressure chamber 570. The volume of the space formed by the third pressure chamber 570 and the valve chamber 521 increases, and the air pressure therein pulls the fourth valve flap 540 away from the sixth water outlet 143. This opens the sixth water outlet 143, allowing water to flow through the first water inlet channel 111, the sixth water inlet channel 141, the sixth water outlet 143, and the sixth water outlet channel 142 to the fourth waterway 310. When the pull cord 510 is released, the piston 550 returns to its original position under the elastic action of the second elastic member 560, and the fourth valve flap 540 elastically returns to its original position, sealing the sixth water outlet 143.
