[0052] At present, the flushing method of smart toilets is mainly tankless flushing, and its principle is to use a flush valve to achieve flushing. In the related technology, two solenoid valves are generally provided on the flush valve to control the on and off of the side flushing channel and the siphon channel respectively, and the flushing function is controlled by software.

[0053] Based on the above situation, the present application provides a flush valve and a smart toilet for use in a smart toilet, which are helpful in solving the problems of complex structure and difficult adjustment in the related technology.

[0054] To illustrate the specific structure of the flush valve of this application, please refer to Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the assembly structure of the first embodiment of the flush valve of the present application. Figure 2 yes Figure 1 Schematic diagram of the explosion structure of the middle flush valve.

[0055] In this embodiment, the flush valve 100 includes a valve body 10, a receiving cavity disposed inside the valve body 10, and a first valve core 21 received in the receiving cavity. The valve body 10 is provided with a water inlet (not shown) connected to the receiving cavity, a first water outlet 11, and a second water outlet 12. The first valve core 21 can rotate relative to the receiving cavity.

[0056] The first side of the accommodating cavity is provided with a first water outlet 11, the second side of the accommodating cavity is provided with a second water outlet 12, the third side of the accommodating cavity is provided with a water inlet and a water inlet channel 103, the water inlet channel 103 is connected with the water inlet, and is used to supply water to the first water outlet 11 and the second water outlet 12. The first side is adjacent to the second side, the second side is adjacent to the third side, and the first side is opposite to the third side.

[0057] The first water outlet 11 is a bottom flushing port (i.e., a siphon port), connected to the bottom flushing pipe 101 and the bottom flushing nozzle, and used to bottom flush the flushing tank of the smart toilet. The second water outlet 12 is a side flushing port, connected to the side flushing pipe 102 and the side flushing nozzle, and used to side flush the flushing tank.

[0058] In this embodiment, the first water outlet 11, the second water outlet 12 and the water inlet are arranged in the same plane, and the bottom flushing pipe 101 and the side flushing pipe 102 are arranged vertically.

[0059] In some embodiments, a braided tube is provided between the bottom flushing pipe 101 and the bottom flushing nozzle.

[0060] In some embodiments, a water inlet valve 30 is installed at the water inlet. Specifically, the water inlet valve 30 and the water inlet pipe 104 are provided on the fourth side of the accommodating chamber, the water inlet valve 30 is provided at one end of the water inlet pipe 104 close to the water inlet channel 103, and the water inlet valve 30 is connected to the water inlet channel 103 located on the third side of the accommodating chamber through the connecting portion of the valve body 10.

[0061] In this embodiment, the edge of the first valve core 21 is connected to the switch assembly 31, and the switch assembly 31 is used to open or close the water inlet channel 103 at the water inlet. When the first valve core 21 is stimulated, it rotates in the accommodating cavity to drive the switch assembly 31 to open or close the water inlet channel 103.

[0062] In some embodiments, one end of the switch assembly 31 is disposed opposite to the water inlet valve 30, and the other end of the switch assembly 31 is connected to the first valve core 21. When the first valve core 21 rotates, the switch assembly 31 is driven to open or close the water inlet valve 30.

[0063] In some implementations, the first valve core 21 is connected to the motor 26 , and when the motor 26 is energized, it drives the first valve core 21 to rotate in the accommodating cavity.

[0064] It can be understood that by setting a switch assembly 31 connected to the first valve core 21 on the edge of the first valve core 21 for controlling the on-off of the water inlet channel, when the first valve core 21 is energized and rotates in the accommodating cavity, the switch assembly 31 can be driven by the rotation of the first valve core 21 to open or close the water inlet valve 30, thereby controlling the on-off of the water inlet channel 103.

[0065] In this embodiment, a sealing member 22 is provided on the edge of the first valve core 21. When the first valve core is stimulated, it rotates in the accommodating cavity so that the sealing member 22 at least partially corresponds to the first water outlet 11 and / or the second water outlet 12, so that the first water outlet 11 and / or the second water outlet 12 is in a closed state or an open state.

[0066] In some specific embodiments, when the blocking member 22 completely corresponds to the first water outlet 11, the first water outlet 11 is completely blocked by the blocking member 22 and is in a closed state, and the second water outlet 12 is in an open state, and the water flow in the water inlet channel 103 only flows out from the second water outlet 12 to side-flush the flushing pool.

[0067] In other specific embodiments, when the blocking member 22 completely corresponds to the second water outlet 12, the second water outlet 12 is completely blocked by the blocking member 22 and is in a closed state, the first water outlet 11 is in an open state, and the water flow in the water inlet channel 103 only flows out from the first water outlet 11 to bottom flush the flushing pool.

[0068] In some other specific embodiments, when the blocking member 22 corresponds to a partial position of the first water outlet 11 and the second water outlet 12, the first water outlet 11 and the second water outlet 12 are in a partially open state, and the water flow in the water inlet channel 103 can flow out from the first water outlet 11 and the second water outlet 12 at the same time to simultaneously perform bottom flushing and side flushing on the flushing pool.

[0069] In other embodiments, when the blocking member 22 corresponds to partial positions of the first water outlet 11 and the second water outlet 12, and the blocking member 22 corresponds to more positions of the first water outlet 11, the opening at the first water outlet 11 is smaller, and the opening at the second water outlet 12 is larger, the water flow rate flowing out of the first water outlet 11 is smaller, and the water flow rate flowing out of the second water outlet 12 is larger, and the side impact force is greater than the bottom impact force.

[0070] In some other specific embodiments, when the blocking member 22 corresponds to partial positions of the first water outlet 11 and the second water outlet 12, and the blocking member 22 corresponds to more positions of the second water outlet 12, the opening at the second water outlet 12 is smaller, and the opening at the first water outlet 11 is larger, the water flow rate flowing out of the first water outlet 11 is larger, and the water flow rate flowing out of the second water outlet 12 is smaller, and the bottom impact force is greater than the side impact force.

[0071] It can be understood that by setting the blocking member 22 at the edge of the first valve core 21, the blocking member 22 can be driven by the rotation of the first valve core 21 to at least partially correspond to the first water outlet 11 and / or the second water outlet 12, so that the first water outlet 11 and / or the second water outlet 12 are in a closed state or an open state, thereby realizing the switching of bottom flushing and side flushing. Furthermore, by adjusting the position of the blocking member 22, the opening size of the first water outlet 11 and / or the second water outlet 12 can also be adjusted, thereby realizing the adjustment of the flushing flow of bottom flushing and side flushing.

[0072] Continue reading Figure 1 and Figure 2 In some implementations, a water diversion valve 20 is installed at the first water outlet 11 and the second water outlet 12 , and the first valve core 21 is the valve core of the water diversion valve 20 .

[0073] In some implementations, the water diversion valve 20 and the water inlet valve 30 share a valve body 10 .

[0074] It can be understood that by integrating the water diverter valve 20 and the water inlet valve 30 into the same valve body 10 and by using the valve core of the water diverter valve 20 to control the water inlet valve 30, the overall size of the flush valve 100 can be reduced, thereby facilitating the installation of the flush valve 100 and the overall layout of the smart toilet.

[0075] In some embodiments, the water inlet valve 30 includes a pilot assembly connected to the water inlet pipe 104, and the pilot assembly includes a first cover 32 and a switch assembly 31. Figure 3 , Figure 3 yes Figure 2 A schematic diagram of the specific structure of the first cover body is shown in FIG. A pilot hole 320 is provided on the first cover body 32, a through hole (not shown) is provided on the inner wall of the valve body 10 located on the fourth side, one end of the switch assembly 31 corresponds to the pilot hole 320 of the water inlet valve 30, and the other end of the switch assembly 31 passes through the through hole and is connected to the first valve core 21.

[0076] Among them, the water inlet valve 30 also includes a water inlet valve housing 35 of the valve body 10 located on the fourth side, the pilot component is accommodated in the water inlet valve housing 35, and the pilot component also includes a pilot diaphragm 34 and a pilot diaphragm bracket 33 supporting the pilot diaphragm 34, and the pilot diaphragm 34 is arranged near the pilot hole 320.

[0077] In some embodiments, the switch assembly 31 includes a piston rod 301 and a reset assembly 303 sleeved on the periphery of the piston rod 301, one end of the reset assembly 303 abuts against the inner wall of the valve body 10 close to the water inlet pipe 104, and the other end of the reset assembly 303 abuts against the end of the piston rod 301 close to the first cover 32. A rubber member 302 is installed at the end of the piston rod 301 close to the first cover 32, and a groove 305 and a column 304 are arranged at the end of the piston rod 301 close to the first valve core 21. The piston rod 301 passes through the through hole of the valve body 10 on the fourth side, so that the groove 305 is engaged with the edge of the first valve core 21, and the column 304 abuts against the first valve core 21. When the first valve core 21 rotates, the reset assembly 303 is stretched or compressed, so that the reset assembly 303 drives the rubber member 302 at the end of the piston rod 301 away from or abuts against the pilot hole 320.

[0078] The reset component 303 is a spring.

[0079] In some specific embodiments, when the first valve core 21 rotates, it stretches the reset assembly 303, and drives the rubber part 302 at the end of the piston rod 301 away from the pilot hole 320 through the reset assembly 303, so as to open the water inlet valve 30, so that the water flow in the water inlet pipe 104 enters the water inlet channel 103, and then supplies water to the first water outlet 11 and / or the second water outlet 12 through the water inlet.

[0080] In some other specific embodiments, when the first valve core 21 rotates, it stretches the reset component 303, and drives the rubber part 302 at the end of the piston rod 301 to abut the pilot hole 320 through the reset component 303, so as to close the water inlet valve 30 by blocking the pilot hole 320, so that the water flow in the water inlet pipe 104 cannot enter the water inlet channel 103.

[0081] Continue reading Figure 1 and Figure 2 In this embodiment, the water diverter valve 20 includes a first valve core 21, a second cover 25, and a motor 26. The second cover 25 is connected to the first valve core 21, and the shape and size of the second cover 25 match the shape and size of the housing at the opening of the accommodating cavity on the valve body 10, and is used to limit the first valve core 21 in the accommodating cavity. A through hole is provided on the second cover 25, and the first valve core 21 passes through the through hole of the second cover 25 and is connected to the motor 26.

In this embodiment, the first valve core 21 includes a rotating shaft 23 and a diverter disc assembly 24. One end of the rotating shaft 23 is fixedly set on the diverter disc assembly 24, and the other end passes through the through hole 251 of the second cover body 25 to connect with the motor 26, so as to drive the rotating shaft 23 to rotate through the motor 26, and then drive the diverter disc assembly 24 to rotate through the rotating shaft 23. A limiting rib 232 is provided on the rotating shaft 23, and a limiting member 252 is provided on the second cover body 25. The limiting rib 232 on the rotating shaft 23 cooperates with the limiting member 252 on the second cover body 25 to limit the rotation angle of the first valve core 21.

[0084] In some specific implementations, the turntable 240 is circular in shape.

[0085] In some specific implementations, the diameter of the first arc segment 241 is equal to the diameter of the rotating disk 240 .

[0086] Continue reading Figure 2 and Figure 4 In some embodiments, one end of the switch assembly 31 close to the first valve core 21 is inserted into the inner side of the first arc segment 241, the second arc segment 242 and the straight segment 243, and abuts against the first arc segment 241, the second arc segment 242 or the straight segment 243. When the first valve core 21 rotates until the first arc segment 241 abuts against the switch assembly 31, the switch assembly 31 closes the water inlet channel 103. When the first valve core 21 rotates until the straight segment 243 or the second arc segment 242 abuts against the switch assembly 31, the switch assembly 31 opens the water inlet channel 103.

[0087] Specifically, the column 304 of the switch assembly 31 is inserted inside the first arc segment 241 , the second arc segment 242 and the straight segment 243 , and abuts against the rotating disk 240 and the first arc segment 241 , the second arc segment 242 or the straight segment 243 .

[0088] In this embodiment, when the rotating shaft 23 drives the diverter disc assembly 24 to rotate, under the joint action of the turntable 240 and the reset assembly 303, the piston rod 301 has four working states: 1) when the turntable 240 rotates to the first arc segment 241 and abuts against the column 304, the turntable 240 is controlled to rotate within the arc corresponding to the first arc segment 241, and the rubber member 302 at the end of the piston rod 301 will always maintain a state of abutting against the pilot hole 320 of the first cover body 32, that is, by blocking the pilot hole 320, the piston rod 301 is closed. 1) When the rotating disk 240 rotates from the state where the first arc segment 241 abuts against the column 304 to the state where the straight segment 243 abuts against the column 304, the reset assembly 303 is gradually compressed and drives the piston rod 301 to move away from the first cover body 32, so that the rubber member 302 gradually moves away from the pilot hole 320 until it is completely separated from the pilot hole 320; 2) When the rotating disk 240 rotates from the state where the first arc segment 241 abuts against the column 304 to the state where the straight segment 243 abuts against the column 304, the reset assembly 303 is gradually compressed and drives the piston rod 301 to move away from the first cover body 32, so that the rubber member 302 gradually moves away from the pilot hole 320 until it is completely separated from the pilot hole 320; 3) When the rotating disk 240 rotates from the state where the straight segment 243 abuts against the column 304 When the state is rotated to the second arc segment 242 abutting against the cylinder 304, the reset assembly 303 is in a compressed state, and the rubber piece 302 at the end of the piston rod 301 is in a non-contact state with the pilot hole 320, that is, the pilot hole 320 is in an open state, and the control dial 240 rotates within the arc corresponding to the second arc segment 242, and the rubber piece 302 at the end of the piston rod 301 will always maintain a distance from the pilot hole 320, so that the pilot hole 320 is always in an open state, that is, the water inlet valve 30 is always in Open state, so that the water flow in the water inlet pipe 104 enters the water inlet channel 103, and supplies water to the first water outlet 11 and / or the second water outlet 12 through the water inlet; 4) When the turntable 240 rotates from the state where the second arc segment 242 abuts against the column 304 to the state where the straight segment 243 abuts against the column 304, the reset assembly 303 gradually resets and drives the piston rod 301 to move toward the direction close to the first cover body 32, so that the rubber member 302 gradually approaches the pilot hole 320 until it is completely abutted against the pilot hole 320.

[0089] Please refer to Figure 7 and Figure 8 , Figure 7 yes Figure 2 Cross-sectional view of the flush valve when the middle pilot hole is in the closed state. Figure 8 yes Figure 2Cross-sectional view of the flush valve when the pilot hole is in the open state. In this embodiment, when the reset assembly 303 is in the reset state, the rubber member 302 is in contact with the pilot hole 320, and the driving force F1 provided by the reset assembly 303 to the rubber member 302 is greater than the pressure F2 of the water flow on the rubber member 302, so as to ensure that the pilot hole 320 is blocked by the rubber member 302 and is in the closed state, thereby closing the water inlet valve 30. When the reset assembly 303 is compressed, the piston rod 301 and the rubber member 302 are driven away from the pilot hole 320, so that the pilot hole 320 is in the open state, thereby opening the water inlet valve 30.

[0090] In some implementations, the diameter of the pilot hole 320 is 0.8 mm to 1.2 mm.

[0091] Specifically, according to the pressure formula F=P*S, where F represents force, S represents force area, and P represents pressure, the smaller the area of ​​the pilot hole 320 is, the smaller the pressure F2 of the water flow on the rubber part 302 is, and the driving force F1 required to be provided by the reset component 303 is correspondingly smaller, and the power and size of the motor 26 corresponding to the water diverter valve 20 are smaller. When the diameter of the pilot hole 320 is within the above range, the switching function of the water inlet valve 30 can be realized while lowering the water diverter valve 20.

[0092] In some embodiments, a leakage hole is provided on the pilot diaphragm support 33. When the pilot hole 320 is opened from closed to open, the pressure on both sides of the pilot diaphragm 34 is equal, and the pilot diaphragm 34 is in a static state. Afterwards, the water on the side of the pilot diaphragm 34 close to the pilot hole 320 will first flow into the water diverter valve 20 through the pilot hole 320. At this time, the water pressure on the side of the pilot diaphragm 34 close to the pilot hole 320 will drop instantly, resulting in an imbalance in the pressure on both sides of the pilot diaphragm 34. Under the action of the water pressure, the pilot diaphragm 34 continues to move, thereby stably opening the water inlet valve 30 to supply water to the water diverter valve 20.

[0093] Further, in this embodiment, a blocking member 22 is provided at the edge of the diverter disk assembly 24, and the blocking member 22 rotates with the rotation of the diverter disk assembly 24. In some embodiments, the blocking member 22 is movably mounted on the edge of the diverter disk assembly 24.

[0094] For details, please refer to Figure 5 and Fig. 9 , Fig. 9 yes Figure 2Schematic diagram of the structure in which the first valve core is equipped with a blocking member. In this embodiment, a plurality of arc-shaped retaining walls 231 are arranged on the rotating shaft 23 of the first valve core 21, and gaps are arranged between the plurality of arc-shaped retaining walls 231. The blocking member 22 includes a third circular arc segment 221 and a clamping member 222 arranged on the third circular arc segment 221. The diameter of the third circular arc segment 221 is equal to the diameter of the first circular arc segment 241. The clamping member 222 is accommodated in the gap and is movably connected to the rotating disk 240 so that the blocking member 22 can move radially along the rotating disk 240.

[0095] The third arc segment 221 is a baffle with an arc.

[0096] In this embodiment, the blocking member 22 is used to block the first water outlet 11 and / or the second water outlet 12 as the turntable 240 rotates, so as to realize the corresponding side flushing function and / or bottom flushing (siphon) function.

[0097] Among them, the blocking member 22 is movably installed on the first valve core 21, which is beneficial to make the blocking member 22 radially close to the inner wall of the valve body 10 under the action of water pressure. When the blocking member 22 completely blocks the first water outlet 11 or the second water outlet 12, it is beneficial to further reduce the water flow from the first water outlet 11 or the second water outlet 12, thereby further enhancing the side flushing effect or the bottom flushing effect.

[0098] Please refer to Fig.10 , Fig.11 and Fig.12 , Fig.10 yes Figure 1 Schematic diagram of the structure in which the middle plugging piece completely blocks the first water outlet, Fig.11 yes Figure 1 Schematic diagram of the structure in which the middle plugging piece completely blocks the second water outlet. Fig.12 yes Figure 1 Schematic diagram of the structure in which the middle blocking member blocks part of the first water outlet and part of the second water outlet at the same time.

[0099] In some embodiments, when the blocking member 22 completely blocks the first water outlet 11, the water in the water inlet channel 103 flows out only from the second water outlet 12, and the flushing pool is flushed sideways through the side flushing pipe 102 and the side flushing nozzle. When the blocking member 22 completely blocks the second water outlet 12, the water in the water inlet channel 103 flows out only from the first water outlet 11, and the flushing pool is flushed bottomwise through the bottom flushing pipe 101 and the bottom flushing nozzle. When the blocking member 22 is located between the first water outlet 11 and the second water outlet 12, the blocking member 22 corresponds to a portion of the first water outlet 11 and the second water outlet 12, and the water in the water inlet channel 103 flows out from the first water outlet 11 and the second water outlet 12 at the same time, so as to flush the flushing pool bottomwise and sideways at the same time.

[0100] In some specific embodiments, when the pilot hole 320 is in an open state, the water inlet valve 30 supplies water to the water diverter valve 20, and the first valve core 21 of the water diverter valve 20 rotates, so that the blocking member 22 completely blocks the first water outlet 11, and the water flows into the side flushing pipe 102 from the second water outlet 12, thereby realizing the side flushing function. After the side flushing is completed, the first valve core rotates under the drive of the motor 26, so that the blocking member 22 completely blocks the second water outlet 12, so as to expose the first water outlet 11, and the water flows into the bottom flushing pipe 101 from the second water outlet 12, thereby realizing the bottom flushing function. In the process of switching from side flushing to bottom flushing, the pilot hole 320 is always in an open state. When simultaneous flushing is required, the first valve core 21 is driven to rotate by the motor 26 to rotate the blocking member 22 to between the first water outlet 11 and the second water outlet 12, that is, a portion of the first water outlet 11 and the second water outlet 12 are exposed, and water flows out from the first water outlet 11 and the second water outlet 12 respectively, so as to realize the bottom flushing and side flushing functions at the same time.

[0101] It can be understood that by adjusting the degree of blocking of the first water outlet 11 and / or the second water outlet 12 by the blocking member 22, the opening of the first water outlet 11 and the second water outlet 12 can be adjusted, thereby achieving flow distribution of bottom flushing and side flushing.

[0102] It can be understood that by driving the first valve core 21 to rotate through a motor 26 to control the opening or closing of the water inlet valve 30, the number of motors in the flush valve 100 can be reduced, thereby not only reducing the overall size of the flush valve 100, but also effectively reducing the manufacturing cost.

[0103] Continue reading Figure 1 and Figure 2 In this embodiment, the water inlet valve 30 includes an air isolation valve 40 arranged at the water inlet, and the opening and closing state of the air isolation valve 40 is opposite to the opening and closing state of the water inlet valve 30.

[0104] In some embodiments, the air isolation valve 40 includes a second valve core 41, a second valve core bracket 42, a sealing gasket 43 and an air isolation valve seat 44. The second valve core 41 is the air isolation valve core. The air isolation valve seat 44 is installed in the housing of the valve body 10 close to the third side, and is used to accommodate the second valve core 41, the second valve core bracket 42 and the sealing gasket 43. The second valve core bracket 42 is used to support the second valve core 41, and the sealing gasket 43 is arranged around the second valve core 41.

[0105] For details, please refer to Fig.13 and Fig.14 , Fig.13 yes Figure 1 Cross-section of the flush valve with the air isolation valve in the closed position. Fig.14 yes Figure 1A cross-sectional view of the flush valve when the air isolation valve is in an open state. In this embodiment, a water supply channel 105 is formed between the air isolation valve 40 and the side flushing pipe 102, and a one-way valve 50 is arranged in the water supply channel 105.

[0106] In some implementations, when the water inlet valve 30 is in an open state, the air isolation valve 40 is in a closed state. At this time, the water flow will push the second valve core 41 upward to make the second valve core 41 contact with the sealing gasket 43 to achieve a sealing effect.

[0107] In other embodiments, when the water inlet valve 30 is in a closed state, the air isolation valve 40 is in an open state, and the second valve core 41 falls downward without contacting the sealing gasket 43, so that the inside of the valve body 10 is connected to the atmosphere, which has the effect of reducing siphoning and reducing backflow. The way in which air enters the valve body 10 is referred to Fig.14 The solid arrow indicates the direction. At this time, the water flowing out of the air isolation valve 40 will enter the side flushing pipe 102 along the water supply channel 105. The water flow direction is referenced to Fig.14 In the direction indicated by the middle dotted arrow, since a one-way valve 50 is provided in the water supply channel 105, when water flows from the air isolation valve 40 to the side flush pipe 102, the water supply channel 105 is connected, and when water flows from the side flush pipe 102 to the air isolation valve 40, the water supply channel 105 is disconnected. Therefore, there is no need to separately set up a silicone tube to drain the water in the air isolation valve 40, and the probability of water backflow from the side flush pipe 102 can also be reduced, thereby further reducing the preparation cost of the flush valve 100.

[0108] See also Fig.15 and Fig.16 , Fig.15 It is a schematic diagram of the assembly structure of the second embodiment of the flush valve of the present application. Fig.16 yes Fig.15 Schematic diagram of the explosion structure of the middle flush valve.

[0109] In this embodiment, the flush valve 100 includes a valve body 10, a receiving cavity disposed inside the valve body 10, and a first valve core 21 received in the receiving cavity. The valve body 10 is provided with a water inlet (not shown) connected to the receiving cavity, a first water outlet 11, and a second water outlet 12. The first valve core 21 can rotate relative to the receiving cavity.

[0110] The first side of the accommodating cavity is provided with a first water outlet 11, the second side of the accommodating cavity is provided with a second water outlet 12, the third side of the accommodating cavity is provided with a water inlet and a water inlet channel 103, the water inlet channel 103 is connected with the water inlet, and is used to supply water to the first water outlet 11 and the second water outlet 12. The first side is adjacent to the second side, the second side is adjacent to the third side, and the first side is opposite to the third side.

[0111] The first water outlet 11 is a bottom flushing port, connected to the bottom flushing pipe 101 and the bottom flushing nozzle, and is used to bottom flush the flushing pool of the smart toilet. The second water outlet 12 is a side flushing port, connected to the side flushing pipe 102 and the side flushing nozzle, and is used to side flush the flushing pool.

[0112] In this embodiment, a water inlet valve 30 is installed at the water inlet, and the water inlet valve 30 and the water inlet pipe 104 are provided on the fourth side of the accommodating chamber. The water inlet valve 30 is arranged at one end of the water inlet pipe 104 close to the water inlet channel 103, and the water inlet valve 30 is connected to the water inlet channel 103 located on the third side of the accommodating chamber through the connecting part of the valve body 10.

[0113] In this embodiment, a water diversion valve 20 is installed at the first water outlet 11 and the second water outlet 12, and the first valve core 21 is the valve core of the water diversion valve 20. The water diversion valve 20 and the water inlet valve 30 share a valve body 10.

[0114] For the specific structures of the water inlet valve 30 and the water diversion valve 20 , please refer to the relevant description in the first embodiment.

[0115] In this embodiment, the water inlet valve 30 includes a pilot assembly connected to the water inlet pipe 104 , and the pilot assembly includes a first cover body 32 and a switch assembly 31 .

[0116] In this embodiment, the edge of the first valve core 21 is connected to the switch assembly 31, and the switch assembly 31 is used to open or close the water inlet channel 103 at the water inlet. When the first valve core 21 is stimulated, it rotates in the accommodating cavity to drive the switch assembly 31 to open or close the water inlet channel 103.

[0117] Among them, the specific structure of the first cover body 32, the specific structure of the switch assembly 31, the connection relationship between the switch assembly 31 and the first cover body 32, and the connection relationship and driving relationship between the switch assembly 31 and the first valve core 21 can be referred to the relevant description in the first embodiment.

[0118] Only the parts of this embodiment that are different from the first embodiment will be described below.

[0119] In this embodiment, the first water outlet 11, the second water outlet 12 and the water inlet are not arranged in the same plane, and the bottom flushing pipe 101 and the side flushing pipe 102 are arranged in parallel.

[0120] Among them, the valve body 10 used to form the accommodating cavity has a certain length in the first direction, and the first water outlet 11 is arranged away from the second cover body 25, and the second water outlet 12 is arranged close to the second cover body 25, so that the bottom flushing pipe 101 and the side flushing pipe 102 can be arranged in parallel, and a herringbone structure is formed between the cross-sections of the bottom flushing pipe 101, the side flushing pipe 102 and the water inlet pipe 104 cut along the axial direction.

[0121] The first direction is the axial extension direction of the rotating shaft 23 .

[0122] It can be understood that the above-mentioned pipeline arrangement method can enable the flush valve 100 to be applied to more installation scenarios, thereby expanding the scope of use of the flush valve 100.

[0123] Please refer to Fig.17 and Fig.18 , Fig.17 yes Fig.16 A top view of the first valve core in FIG. Fig.18 yes Fig.16 Bottom view of the first valve core.

[0124] In this embodiment, the rotating disk 240 of the diverter disk assembly 24 is in an irregular semicircular arc shape. A first arc segment 241 and a second arc segment 242 are arranged on the circumference of the rotating disk 240. The first arc segment 241 and the second arc segment 242 are arranged concentrically. The diameter of the first arc segment 241 is greater than the diameter of the second arc segment 242. The first arc segment 241 and the second arc segment 242 are connected by a straight line segment 243.

[0125] Compared to the circular rotating disk in the first embodiment, the curvature of the first arc segment 241 and the second arc segment 242 in this embodiment are only half of the corresponding arc segments in the first embodiment.

[0126] It can be understood that when the first arc segment 241 and the second arc segment 242 with smaller arcs can achieve the same driving effect, reducing the arcs of the first arc segment 241 and the second arc segment 242 and reducing the size of the turntable 240 can further reduce the amount of preparation materials used, thereby further reducing the preparation cost of the flush valve 100.

[0127] Please refer to Fig.19 and Fig. 20 , Fig.19 yes Fig.16 Schematic diagram of the specific structure of the plugging piece. Fig. 20 yes Fig.15 Schematic diagram of the structure in which the middle blocking member completely blocks the first water outlet.

[0128] In this embodiment, the blocking member 22 includes a third arc segment 221 and a clamping member 222 arranged on the third arc segment 221. The diameter of the third arc segment 221 is equal to the diameter of the first arc segment 241. The clamping member 222 is accommodated in the gap and is movably connected to the turntable 240 so that the blocking member 22 can move radially along the turntable 240.

[0129] In this embodiment, a pressure relief hole 223 is provided at one end of the blocking member 22 close to the first water outlet 11. The pressure relief hole 223 is used to divert the water flow entering the accommodating cavity when the blocking member 22 completely corresponds to the first water outlet 11.

[0130] It can be understood that when the length of the valve body 10 corresponding to the accommodating cavity is increased, in order to enable the blocking member 22 to block the first water outlet 11 and the second water outlet 12, the length of the third arc segment 221 along the first direction will be increased accordingly compared with the first embodiment, and the corresponding area will be increased accordingly. According to the pressure formula F=P*S, where F represents force, S represents the force-bearing area, and P represents pressure, the larger the area of ​​the third arc segment 221, the smaller the diameter of the second water outlet 12, if the water flow entering the accommodating cavity in the water inlet channel 103 When the third arc segment 221 is larger and the sealing member 22 completely blocks the first water outlet 11, the side flushing flow will be larger. At this time, the pressure of the water flow on the third arc segment 221 will be greater, resulting in a high water pressure entering the water diverter valve 20, which may cause the first valve core 21 to fail to rotate normally. At this time, a pressure relief hole 223 is set at one end of the third arc segment 221 close to the first water outlet 11, which can divert the water flow from the pressure relief hole 223 into the first water outlet 11, so as to reduce the internal pressure of the water diverter valve 20 through the diversion effect of the first water outlet 11, and at the same time achieve the purpose of reducing the side flushing flow.

[0131] In this embodiment, the air isolation valve 40 includes a second valve core 41, a sealing gasket 43 and an air isolation valve seat 44. The second valve core 41 is the air isolation valve core. The air isolation valve seat 44 is installed in the housing of the valve body 10 close to the third side, and is used to accommodate the second valve core 41 and the sealing gasket 43. The sealing gasket 43 is arranged around the second valve core 41.

[0139] In this embodiment, the water inlet valve 30 includes a pilot assembly connected to the water inlet pipe 104 , and the pilot assembly includes a first cover body 32 and a switch assembly 31 .

[0140] In this embodiment, the edge of the first valve core 21 is connected to the switch assembly 31, and the switch assembly 31 is used to open or close the water inlet channel 103 at the water inlet.

[0147] In this embodiment, when the rotating shaft 23 drives the diverter disc assembly 24 to rotate, under the joint action of the rotating disc 240 and the reset assembly 303, the piston rod 301 has four working states: 1) When the rotating disc 240 rotates to the second arc segment 242 and abuts against the piston rod 301, the rotating disc 240 is controlled to rotate within the arc corresponding to the second arc segment 242, and the annular gasket 306 in the middle of the piston rod 301 will always maintain a state of abutting against the pilot hole 320 on the valve body 10, that is, by blocking the pilot hole 320 0 closes the water inlet valve 30, so that the water in the water inlet pipe 104 cannot enter the water inlet channel 103; 2) when the rotating disk 240 rotates from the state where the second arc segment 242 abuts against the piston rod 301 to the state where the straight segment 243 abuts against the piston rod 301, the reset assembly 303 is gradually compressed and drives the annular gasket 306 to move away from the pilot hole 320, so that the annular gasket 306 gradually moves away from the pilot hole 320 until it is completely separated from the pilot hole 320; 3) when the rotating disk 240 rotates from the state where the straight segment 243 abuts against the piston rod 301, the reset assembly 303 is gradually compressed and drives the annular gasket 306 to move away from the pilot hole 320, so that the annular gasket 306 gradually moves away from the pilot hole 320 until it is completely separated from the pilot hole 320. When the plug rod 301 is in contact with the first arc segment 241 and rotates to contact the piston rod 301, the reset assembly 303 is in a compressed state, and the annular gasket 306 and the pilot hole 320 are in a non-contact state, that is, the pilot hole 320 is in an open state, and the control dial 240 rotates within the arc corresponding to the first arc segment 241, and the annular gasket 306 will always maintain a distance from the pilot hole 320, so that the pilot hole 320 is always in an open state, that is, the water inlet valve 30 is always in an open state. So that the water flow in the water inlet pipe 104 enters the water inlet channel 103 and supplies water to the first water outlet 11 and / or the second water outlet 12 through the water inlet; 4) When the turntable 240 rotates from the state where the first arc segment 241 abuts against the piston rod 301 to the state where the straight segment 243 abuts against the piston rod 301, the reset assembly 303 gradually resets and drives the annular gasket 306 to move toward the direction close to the pilot hole 320, so that the annular gasket 306 gradually approaches the pilot hole 320 until it is completely abutted against the pilot hole 320.

[0148] The present application provides a smart toilet, comprising a toilet body and the above-mentioned flush valve.

[0149] The present application provides a water inlet, a first water outlet and a second water outlet connected to the accommodating chamber on the valve body of the flush valve, and allows the first valve core to be rotatably accommodated in the accommodating chamber, and provides a switch assembly connected to the first valve core on the edge of the first valve core for controlling the on-off of the water inlet channel. When the first valve core is stimulated and rotates in the accommodating chamber, the first valve core can be driven to rotate and drive the switch assembly to open or close the water inlet channel, thereby controlling the on-off of the water inlet pipeline. Further, by providing a blocking member on the edge of the first valve core, the blocking member can also be driven by the rotation of the first valve core to at least partially correspond to the first water outlet and / or the second water outlet, so that the first water outlet and / or the second water outlet are in a closed state or an open state, thereby realizing the switching between bottom flushing and side flushing, and realizing the adjustment of the flushing flow of bottom flushing and / or side flushing. Further, by driving the first valve core to rotate by a motor to control the opening or closing of the water inlet valve, the number of motors in the flush valve can be reduced, thereby not only reducing the overall size of the flush valve, but also effectively reducing the manufacturing cost.

[0150] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
