[0002] Toilets are becoming increasingly popular in homes and commercial areas due to their convenience and comfort. Traditional toilets are relatively large in size and occupy a large amount of space, making it difficult to adapt well to small bathrooms for home or commercial use.

[0003] Among the current flushing methods for toilets, one is to use a pressurized water source to flush the toilet. The pressurized water source is distributed to the basin outlet or the siphon opening through a switching valve driven by a stepper motor.

[0065] The following further illustrates the specific implementation manners of the present invention with reference to the accompanying drawings.

[0066] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, there are various structural ways and implementation ways that can be mutually replaced by those of ordinary skill in the art. Therefore, the following specific implementation manners and the accompanying drawings are only exemplary illustrations of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the invention.

[0067] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings, and they are relative concepts. Therefore, they may change accordingly depending on their different positions and different usage states. So, these or other orientation terms should not be interpreted as restrictive terms either.

[0068] The present application provides a water path switching assembly 100, which includes a control pipe 1, a water inlet pipe 3, a first water outlet pipe 4, and a second water outlet pipe 5 that are all connected to the control pipe 1, and a control member.

[0069] Among them, as Figure 1 shown, the control pipe 1 includes a first control end 10, a second control end 11 arranged along the length direction, and a side opening 12 formed between the first control end 10 and the second control end 11; a valve core 2 is movably arranged between the first control end 10 and the second control end 11 inside the control pipe 1. The water path switching assembly 100 in the embodiment of the present application can be in an "h" shape or an "n" shape.

[0070] When the valve core 2 moves to the first control end 10, the valve core 2 and the first control end 10 are on the same side of the side opening 12; the valve core 2 and the second control end 11 are on the same side of the side opening 12.

[0071] Please refer to Figure 4 and Figure 5 simultaneously. The valve core 2 and the first control end 10 being on the same side of the side opening 12 means that when the valve core 2 moves to the first control end 10, the valve core 2 is entirely on the side of the inner wall of the side opening 12 close to the first control end 10, or the valve core 2 is partially located between the inner walls of the side opening 12. It meets the requirement that when the side opening 12 supplies water to the control pipe 1, the water pressure maintains the valve core 2 in contact with the first control end 10.

[0072] Please refer to Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , when the valve core 2 and the second control end 11 are on the same side of the side opening 12, it means that when the valve core 2 moves to the second control end 11, the valve core 2 is entirely on the side of the inner wall of the side wall opening 12 close to the inner wall of the second control end 11, or part of the valve core 2 is between the inner walls of the side opening 12. This satisfies the effect that when the side opening 12 supplies water to the control pipe 1, the valve core 2 remains in contact with the second control end 11.

[0073] The first water outlet pipe 4 is connected to the first control end 10, and the first water outlet pipe 4 includes a first water outlet 40. Taking the example that in the initial state, the valve core 2 and the second control end 11 are on the same side of the side opening 12, during a single water path switching process, after the first water supply from the water inlet pipe 3 to the control pipe 1 ends, the valve core 2 moves to the first control end 10 under the action of the inertial force of the water flow in the first water outlet pipe 4. At the moment when the first water supply from the water inlet pipe 3 to the control pipe 1 stops during a single water path switching process, the water flow flowing at the first water outlet 40 of the first water outlet pipe 4 pulls the valve core 2 through inertial force, and the valve core 2 moves to the first control end 10 under the pulling action of the inertial force, as Figure 4 shown. Among them, the first water outlet pipe 4 is a U-shaped pipe, and the first water outlet 40 and the opening of the first water outlet pipe 4 connected to the control pipe 1 are the two ends of the U-shaped pipe. The second water outlet pipe 5 is connected to the second control end 11, as Figures 1 to 9 shown.

[0074] The control member is used to control the water supply time and the water cut-off interval of the water flow entering the control pipe 1 from the water inlet pipe 3, so as to control the water output of the first water outlet pipe 4 and the second water outlet pipe 5, and realize the alternate water supply to the sanitary equipment, such as realizing toilet flushing, etc. The control member in the embodiment of the present application can be a water flow switch, and the water supply time and the water cut-off interval of the water flow entering the control pipe 1 from the water inlet pipe 3 are controlled through the water flow switch. The control member in the embodiment of the present application can also be a control device preset with a water supply time and a water cut-off interval, and the water inlet pipe 3 is controlled to intake water according to the preset water supply time and water cut-off interval.

[0075] The following introduces the single water path switching process of the water path switching component. Taking the example that in the initial state, the valve core 2 and the second control end 11 are on the same side of the side opening 12, the control member controls the water inlet pipe 3 to supply water to the control pipe 1 for the first time according to the water supply time, as Figure 3 shown, so that the first water outlet 40 of the first water outlet pipe 4 discharges water. At the moment when the first water supply of the water inlet pipe 3 stops, the valve core 2 is pulled up to abut against the first control end 10 under the action of the inertial pulling force of the water flow in the first water outlet pipe 4, as Figure 4As shown. When there is a water supply interruption interval, the water inlet pipe 3 starts to supply water to the control pipe 1 for the second time according to the water supply time, so as to limit the valve core 2 at the first control end 10 by water pressure before the valve core 2 leaves the first control end 10, so that the second water outlet pipe 5 discharges water, as Figure 5 . After the water inlet pipe 3 stops the second water supply, the valve core 2 moves under the inertial force of the water flow in the second water outlet pipe 5 to abut against the second control end 11, as Figure 6 shown.

[0076] The water path switching assembly 100 provided by the embodiment of the present application controls the water supply time and the water supply interruption interval of the water flow in the water inlet pipe 3 entering the control pipe 1, so as to realize the alternating water discharge of the first water outlet pipe 4 and the second water outlet pipe 5, so as to realize a single water path switching. The above water path switching process is controlled and completed by the water path switching assembly 100, without additionally arranging components such as a motor switching valve and a motor control part required for controlling flushing, improving the water path switching effect, reducing the cost, simplifying the design, and saving space.

[0077] As an optional embodiment, the first control end 10 is located above the second control end 11. As Figure 1 shown, in this embodiment, in the initial state, the ball valve 2 abuts against the second control end 11 under the action of water pressure. During the single water path switching process, at the moment when the first water supply of the water inlet pipe 3 to the control pipe 1 stops, the water flow flowing at the first water outlet 40 of the first water outlet pipe 4 pulls up the valve core 2 by inertial force, and the valve core 2 moves to the first control end 10 by overcoming its own gravity under the pulling action of the inertial force, as Figure 4 shown. When there is a water supply interruption interval, the water inlet pipe 3 starts to supply water to the control pipe 1 for the second time according to the water supply time, so as to limit the valve core 2 at the first control end 10 by water pressure before the valve core 2 falls, so that the second water outlet pipe 5 discharges water, as Figure 5 shown. After the water inlet pipe 3 stops the second water supply, the valve core 2 moves to abut against the second control end 11, as Figure 6 shown. When the third water supply stops, the valve core 2 maintains the state of abutting against the second control end 11 under the action of its own gravity, as Figure 9 shown.

[0078] As an optional embodiment, the water supply time includes a first water supply time and a second water supply time, and the water stop interval includes a first water stop interval. The water inlet pipe 3 supplies water to the control pipe 1 for the first time according to the first water supply time, and the valve core 2 is limited at the second control end 11 under the action of water pressure, so that the first water outlet 40 of the first water outlet pipe 4 discharges water. When the first water supply of the water inlet pipe 3 stops, the valve core 2 is pulled and moved to the first control end 10 under the action of the inertial pulling force of the water flow in the first water outlet pipe 4. The height of the first water outlet 40 is lower than the height of the first control end 10, so that the valve core 2 is adsorbed at the first control end 10 under the action of the gravity of the water flow in the first water outlet pipe 4. During a single water path switching process, at the moment when the first water supply of the water inlet pipe 3 to the control pipe 1 stops, the water flow flowing at the first water outlet 40 of the first water outlet pipe 4 pulls the valve core 2 towards the position of the first control end 10 by inertia force, and the valve core 2 moves to the first control end 10 by overcoming its own gravity under the pulling action of the inertia force. Since the height of the first water outlet 40 is lower than that of the valve core 2, the inverted "U" shape of the first water outlet pipe 4 converts the gravity of the water flow into the suction force on the valve core 2, so that the valve core 2 maintains the position of abutting against the first control end 10, as Figure 4 shown.

[0079] When the water inlet pipe 3 starts to supply water to the control pipe 1 for the second time according to the second water supply time after an interval of the first water stop interval, the valve core 2 is limited at the first control end 10 by water pressure before it falls, and the second water outlet pipe 5 discharges water, as Figure 5 shown. After the second water supply of the water inlet pipe 3 stops, the valve core 2 moves to the second control end 11, as Figure 6 . Specifically, at the moment when the second water supply of the water inlet pipe 3 to the control pipe 1 stops, the water flow in the second water outlet pipe 5 pulls and limits the valve core 2 at the second control end 11 by inertia force. The water outlet of the second water outlet pipe 5 is lower than the valve core 2, which changes the gravity of the water into the suction force on the valve core 2 and jointly maintains the position of the valve core 2 unchanged with the gravity action of the valve core 2. At the same time, air 9 gradually enters from the side of the first water outlet pipe 4, and the air 9 destroys the inertia force of the water in the second water outlet pipe 5 on the valve core 2. The second water supply time in this embodiment can be 4s, or can be selected between 2s - 10s to achieve the water discharge effect of the second water outlet pipe 5. The first water stop interval can be 0.5s, or can be selected between 0.1 - 1.0s, with the start of the second water supply as the criterion before the air 9 gradually entering from the first water outlet 40 destroys the suction force of the water flow inertia force on the valve core 2 and causes the valve core 2 to fall.

[0080] As an optional embodiment, the water supply time further includes a third water supply time, and the water stop interval further includes a second water stop interval. The water inlet pipe 3 starts to supply water to the control pipe 1 for the third time according to the third water supply time after an interval of the second water stop interval, as Figure 7 , Figure 8As shown. After the water inlet pipe 3 stops the third water supply, the valve core 2 is limited at the second control end 11 to restore the initial state, as Figure 9 shown. Specifically, during the third water supply, the valve core 2 is limited at the second control end 11 under the action of its own gravity and the attraction of the water flow in the second water outlet pipe 5, so that the water flow in the control pipe 1 enters the first water outlet pipe 4. When the third water supply stops, when the inertial force of the water flow in the first water outlet pipe 4 is not sufficient to overcome the attraction of the water flow in the second water outlet pipe 5 to the valve core 2, the valve core 2 maintains the state of abutting against the second control end 11, as Figure 9 shown.

[0081] As an optional embodiment, a first step 13 for limiting the valve core 2 is provided at the first control end 10, and a second step 14 for limiting the valve core 2 is provided at the second control end 11. As Figures 1 to 9 shown, the first step 13 in the embodiment of the present application plays a role of abutting and limiting the valve core 2 at the first control end 10, and the second step 14 plays a role of abutting and limiting the valve core 2 at the second control end 11. When the valve core 2 moves to the first step 13, the side opening 12 is located below the valve core 2; when the valve core 2 moves to the second step 14, the side opening 12 is located above the valve core 2.

[0082] As an optional embodiment, there is a gap between the valve core 2 and the second step 14. In the embodiment of the present application, the gap left between the valve core 2 and the second step 14 can be used as a water drainage channel. A notch is provided on the second step 14 to form a gap defined by the notch and the valve core 2 when the spherical valve core 2 abuts against the annular second step 14, as Figure 2 shown. After the second water supply ends, air 9 gradually enters from the side of the first water outlet pipe 4, and the air 9 enters the second water outlet pipe 5 through the above-mentioned water drainage channel to destroy the attraction of the water flow in the second water outlet pipe 5 to the valve core 2. After the third water supply ends, air 9 gradually enters from the side of the first water outlet pipe 4, and after passing through the above-mentioned water drainage channel, the air 9 destroys the attraction of the water flow in the second water outlet pipe 5 to the valve core 2, so that the water flow gradually flows out of the second water outlet pipe 5 through the water drainage channel. After a period of time, the water path switching assembly 100 returns to the initial state as Figure 9 shown. The above process is repeated from the first water supply when the water path is switched next time.

[0083] As an optional embodiment, the gap between the valve core 2 and the inner wall of the control pipe 1 is L, and 0.1 mm ≤ L ≤ 2 mm. Setting the gap between 0.1 mm and 2 mm can not only ensure the smooth movement of the valve core 2 in the control pipe 1 driven by the water pressure, but also avoid the large gap between the valve core 2 and the inner wall of the control pipe 1 from affecting the driving effect of the water flow inertia on the valve core 2.

[0084] As an optional embodiment, a one-way control member 30 for allowing water flow to enter the control pipe 1 from the water inlet pipe 3 unidirectionally is provided in the water inlet pipe 3. The one-way control member 30 in the embodiment of the present application is used to isolate the water inlet pipe 3 and the control pipe 1, and at the same time achieve the effect of unidirectionally controlling the water flow to enter the control pipe 1 from the water inlet pipe 3. The one-way control member 30 in the embodiment of the present application can be a one-way valve or a check valve.

[0085] As an optional embodiment, a connecting elbow 31 is provided at one end of the water inlet pipe 3. The connecting elbow 31 is connected to the side opening 12. The connecting elbow 31 is horizontally arranged or inclined downward in the direction towards the side opening 12, and the one-way control member 30 is arranged in the connecting elbow 31. In the embodiment of the present application, the connecting elbow 31 provides an accommodation space for the one-way control member 30. At the same time, the connecting elbow 31 is horizontally arranged or inclined downward in the direction towards the side opening 12, which is beneficial to avoiding water flow from gathering at the connection between the connecting elbow 31 and the control pipe 1 and being unable to be discharged in time.

[0086] The present application also provides a toilet water supply device 600, including: a water path switching component 100 and a toilet body 6.

[0087] The toilet body 6 includes a basin part 60, a cleaning water outlet 61 for supplying water to the basin part 60, and a siphon water outlet 2. Among them, as Figure 1 shown, the water path switching component 100 includes a control pipe 1, a water inlet pipe 3, a first water outlet pipe 4, and a second water outlet pipe 5 that are all connected to the control pipe 1, and a control member. The control pipe 1 includes a first control end 10, a second control end 11 arranged along the length direction, and a side opening 12 opened between the first control end 10 and the second control end 11. A valve core 2 that can be movably arranged between the first control end 10 and the second control end 11 is arranged in the control pipe 1.

[0088] When the valve core 2 moves to the first control end 10, the valve core 2 and the first control end 10 are on the same side of the side opening 12; the valve core 2 and the second control end 11 are on the same side of the side opening 12.

[0089] Please refer to Figure 4 and Figure 5 simultaneously. When the valve core 2 and the first control end 10 are on the same side of the side opening 12, it means that when the valve core 2 moves to the first control end 10, the valve core 2 is entirely located on the side of the inner wall of the side opening 12 close to the first control end 10, or the valve core 2 is partially located between the inner walls of the side opening 12. It meets the requirement that when the side opening 12 supplies water to the control pipe 1, the water pressure maintains the valve core 2 in contact with the first control end 10.

[0090] Please refer to Figure 1 , Figure 3 , Figure 6 , Figure 7 ,Figure 8 and Figure 9 When the valve core 2 and the second control end 11 are on the same side of the side opening 12, it means that when the valve core 2 moves to the second control end 11, the entire valve core 2 is located on the side of the inner wall of the side wall opening 12 close to the second control end 11, or a part of the valve core 2 is located between the inner walls of the side opening 12. This satisfies the effect that when the side opening 12 supplies water to the control pipe 1, the valve core 2 remains in contact with the second control end 11.

[0091] The first water outlet pipe 4 is connected between the first control end 10 and the flushing water outlet 61 of the toilet body 6. The first water outlet pipe 4 includes a first water outlet 40. Taking the example that in the initial state, the valve core 2 and the second control end 11 are on the same side of the side opening 12, after the water supply from the water inlet pipe 3 to the first water outlet pipe 4 stops, the valve core 2 has a tendency to move towards the first control end 10 under the action of the inertia force of the water flow in the first water outlet pipe 4. During a single flushing process, at the moment when the water supply from the water inlet pipe 3 to the control pipe 1 stops for the first time, the flowing water at the first water outlet 40 of the first water outlet pipe 4 pulls the valve core 2 through inertia force, and the valve core 2 moves to the first control end 10 under the pulling action of the inertia force, as Figure 4 and Figure 16 shown.

[0092] The second water outlet pipe 5 is connected between the second control end 11 and the siphon water outlet 62 of the toilet body 6, as Figures 1 to 9 、 Figures 12 to 22 shown.

[0093] The control member is used to control the water supply time and the water stop interval of the water flow entering the control pipe 1 from the water inlet pipe 3, so as to drive the valve core 2 to move between the first control end 10 and the second control end 11 of the control pipe 1, control the water outlet of the first water outlet pipe 4 and the second water outlet pipe 5, and flush the toilet body 6. The control member in the embodiment of the present application can be a water flow switch, and the water supply time and the water stop interval of the water flow entering the control pipe 1 from the water inlet pipe 3 are controlled through the water flow switch. The control member in the embodiment of the present application can also be a control device preset with a water supply time and a water stop interval, and the water inlet of the water inlet pipe 3 is controlled according to the preset water supply time and water stop interval.

[0094] The following introduces the process of the toilet water supply device 600 flushing the toilet body 6. Taking the example that in the initial state, the valve core 2 and the second control end 11 are on the same side of the side opening 12, the control member controls the water inlet pipe 3 to supply water to the control pipe 1 for the first time according to the water supply time, as Figure 3 and Figure 15 shown, so that the first water outlet 40 of the first water outlet pipe 4 discharges water to the flushing water outlet 61 of the toilet body 6 for flushing. After the water inlet pipe 3 stops the first water supply, the valve core 2 is lifted and limited at the first control end 10 under the action of the inertial pulling force of the water flow in the first water outlet pipe 4, as Figure 4 、Figure 16 and Figure 17 As shown in Figure 17 . When there is a water supply interruption interval, the water inlet pipe 3 starts to supply water to the control pipe 1 for the second time according to the water supply time, so as to limit the valve core 2 at the first control end 10 by water pressure before the valve core 2 leaves the first control end 10, so that the second water outlet pipe 5 discharges water to carry out siphon sewage discharge at the siphon water outlet 62, as Figure 5 and Figure 18 shown. After the water inlet pipe 3 stops the second water supply, the valve core 2 moves to the second control end 11 under the inertial force of the water flow in the second water outlet pipe 5, completing a flushing of the toilet body 6, as Figure 6 and Figure 19 shown. The toilet water supply device 600 provided by the embodiment of the present application controls the water supply time and the water supply interruption interval of the water flow in the water inlet pipe 3 entering the control pipe 1, realizes the alternating water discharge of the first water outlet pipe 4 connected to the cleaning water outlet 61 and the second water outlet pipe 5 connected to the siphon water outlet 62, and realizes a flushing of the toilet body 6. The above flushing process is controlled by the water path switching component 100, without the need to additionally arrange components such as a motor switching valve and a motor control component required for controlling flushing, improving the flushing effect, reducing the cost, simplifying the design, and saving space.

[0095] As an optional embodiment, the first control end 10 is located above the second control end 11. As Figure 1 shown, in this embodiment, in the initial state, the ball valve 2 abuts against the second control end 11 under the action of water pressure. During a single water path switching process, at the moment when the first water supply of the water inlet pipe 3 to the control pipe 1 stops, the water flow flowing at the first water outlet 40 of the first water outlet pipe 4 pulls up the valve core 2 by inertial force, and the valve core 2 moves to the first control end 10 by overcoming its own gravity under the pulling action of the inertial force, as Figure 4 shown. When there is a water supply interruption interval, the water inlet pipe 3 starts to supply water to the control pipe 1 for the second time according to the water supply time, so as to limit the valve core 2 at the first control end 10 by water pressure before the valve core 2 falls, so that the second water outlet pipe 5 discharges water, as Figure 5 and Figure 18 shown. After the water inlet pipe 3 stops the second water supply, the valve core 2 moves to abut against the second control end 11, as Figure 6 and Figure 19 shown. When the third water supply stops, the valve core 2 maintains the state of abutting against the second control end 11 under its own gravity.

[0096] As an optional embodiment, the water supply time includes a first water supply time and a second water supply time, and the water supply interruption interval includes a first water supply interruption interval. The water inlet pipe 3 supplies water to the control pipe 1 for the first time according to the first water supply time, and the valve core 2 is limited at the second control end 11 under the action of water pressure, so that the first water outlet 40 of the first water outlet pipe 4 discharges water to flush the basin part 60, as Figure 3 and Figure 15As shown. When the water inlet pipe 3 stops the first water supply, the valve core 2 is pulled by the inertial pulling force of the water flow in the first water outlet pipe 4 and moves to the first control end 10. The height of the first water outlet 40 is lower than the height of the first control end 10, so that the valve core 2 is adsorbed and maintained at the first control end 10 under the gravity of the water flow in the first water outlet pipe 4, as Figure 4 , Figure 16 and Figure 17 shown. Specifically, at the moment when the water inlet pipe 3 stops the first water supply to the control pipe 1, the water flow at the first water outlet 40 of the first water outlet pipe 4 pulls the valve core 2 towards the position of the first control end 10 by inertia force, and the valve core 2 moves to the first control end 10 under the pulling action. At the same time, since the height of the first water outlet 40 is lower than that of the valve core 2, the inverted "U" shape structure of the first water outlet pipe 4 changes the gravity of the water into the suction force on the valve core 2 to maintain the valve core 2 limited at the position of the first control end 10. The first water supply time in this embodiment can be 3s, or can be selected between 2s and 10s to achieve a better flushing effect on the basin part 60.

[0097] The water inlet pipe 3 starts to supply water to the control pipe 1 for the second time according to the second water supply time at an interval of the first water stop interval, so as to maintain the valve core 2 limited at the first control end 10 by water pressure before the valve core 2 falls, and the second water outlet pipe 5 discharges water to carry out siphon drainage at the siphon outlet 62, as Figure 5 and Figure 18 shown. After the water inlet pipe 3 stops the second water supply, the valve core 2 moves to the second control end 11, as Figure 6 and Figure 19 shown. Specifically, at the moment when the water inlet pipe 3 stops the second water supply to the control pipe 1, the water flow in the second water outlet pipe 5 pulls and limits the valve core 2 at the second control end 11 by inertia force. The water outlet of the second water outlet pipe 5 is lower than the valve core 2, changing the gravity of the water into the suction force on the valve core 2, and jointly maintaining the position of the valve core 2 unchanged with the gravity action of the valve core 2. At the same time, air 9 gradually enters from the side of the first water outlet pipe 4, and the air 9 destroys the inertial force of the water in the second water outlet pipe 5 on the valve core 2. The second water supply time in this embodiment can be 4s, or can be selected between 2s and 10s to achieve a better siphon drainage effect. The first water stop interval can be 0.5s, or can be selected between 0.1s and 1.0s, starting the second water supply before the air 9 gradually entering from the first water outlet 40 destroys the upward suction force of the water flow inertia force on the valve core 2 and causes the valve core 2 to fall.

[0098] As an optional embodiment, the water supply time further includes a third water supply time, and the water stop interval further includes a second water stop interval; the water inlet pipe 3 starts to supply water to the control pipe 1 for the third time according to the third water supply time at an interval of the second water stop interval, so as to clean the basin part 60 and form a water seal, as Figure 7 , Figure 8 ,Figure 20 , Figure 21 As shown. After the water inlet pipe 3 stops the third water supply, the valve core 2 is limited at the second control end 11 to restore the initial state, as shown in Figure 9 and Figure 22 shown. Specifically, during the third water supply, the valve core 2 is limited at the second control end 11 under the attraction of the water flow in the second water outlet pipe 5, so that the water flow in the control pipe 1 enters the first water outlet pipe 4. When the third water supply stops, when the inertia force of the water flow in the first water outlet pipe 4 is not enough to overcome the attraction of the water flow in the second water outlet pipe 5 to the valve core 2, the valve core 2 maintains the state of abutting against the second control end 11. As an optional embodiment, the first control end 10 is provided with a first step 13 for limiting the valve core 2, and the second control end 11 is provided with a second step 14 for limiting the valve core 2. As shown in Figures 1 to 9 shown, the first step 13 in the embodiment of the present application plays a role of abutting and limiting the valve core 2 at the first control end 10, and the second step 14 plays a role of abutting and limiting the valve core 2 at the second control end 11. When the valve core 2 moves to the first step 13, the side opening 12 is located below the valve core 2; when the valve core 2 moves to the second step 14, the side opening 12 is located above the valve core 2.

[0099] As an optional embodiment, there is a gap between the valve core 2 and the second step 14. In the embodiment of the present application, in the gap left between the valve core 2 and the second step 14, it can be used as a water drainage channel. The gap is realized by providing a notch on the second step 14. When the spherical valve core 2 abuts against the annular second step 14, the notch and the valve core 2 define the gap. After the second water supply ends, air 9 gradually enters from the side of the first water outlet pipe 4, and the air 9 enters the second water outlet pipe 5 through the above-mentioned water drainage channel to destroy the attraction of the water flow in the second water outlet pipe 5 to the valve core 2. After the third water supply ends, air 9 gradually enters from the side of the first water outlet pipe 4, and after the air 9 passes through the above-mentioned water drainage channel, it destroys the attraction of the water flow in the second water outlet pipe 5 to the valve core 2, so that the water flow gradually flows out of the second water outlet pipe 5 through the water drainage channel. After a period of time, the water path switching assembly 100 returns to the initial state as shown in Figure 9 and Figure 22 shown. The next time the toilet flushes, the above process is repeated starting from the first water supply.

[0100] As an optional embodiment, the gap between the valve core 2 and the inner wall of the control pipe 1 is L, and 0.1mm ≤ L ≤ 2mm. Setting the gap between 0.1mm and 2mm can not only ensure the smooth movement of the valve core 2 in the control pipe 1 driven by the water pressure, but also avoid the large gap between the valve core 2 and the inner wall of the control pipe 1 from affecting the driving effect of the water flow inertia on the valve core 2.

[0101] As an alternative embodiment, a one-way control member 30 for allowing water flow to enter the control pipe 1 from the water inlet pipe 3 unidirectionally is provided inside the water inlet pipe 3. The one-way control member 30 in the embodiment of the present application is used to isolate the water inlet pipe 3 and the control pipe 1, and at the same time achieve the effect of unidirectionally controlling the water flow to enter the control pipe 1 from the water inlet pipe 3. The one-way control member 30 in the embodiment of the present application can be a one-way valve or a check valve.

[0102] As an alternative embodiment, one end of the water inlet pipe 3 is provided with a connecting elbow 31. The connecting elbow 31 is connected to the side opening 12. The connecting elbow 31 is horizontally arranged or inclined downward in the direction towards the side opening 12. The one-way control member 30 is arranged inside the connecting elbow 31. In the embodiment of the present application, the connecting elbow 31 provides an accommodation space for the one-way control member 30. At the same time, the connecting elbow 31 is horizontally arranged or inclined downward in the direction towards the side opening 12, which is beneficial to preventing water flow from gathering at the connection between the connecting elbow 31 and the control pipe 1 and being unable to be discharged in time.

[0103] As an alternative embodiment for supplying flushing water to the control pipe 1, the flushing water is located in the water tank 7. A water pump 8 is provided inside the water tank 7. The control member is communicatively connected to the water pump 8 to control the water supply time and the water cut-off interval by controlling the start and stop of the water pump 8. The control member is communicatively connected to the water pump 8, and controls the start and stop of the water pump 8 according to the preset water supply time and water cut-off interval, thereby controlling the first water supply time, the second water supply time, the third water supply time, the first water cut-off interval, and the second water cut-off interval of the water inlet pipe 3. In the embodiment of the present application, an opening switch is provided on the water tank 7 or the toilet body 6. Pressing the opening switch controls the control member to start working.

[0104] As another alternative embodiment for supplying flushing water to the control pipe 1, the flushing water is pressurized water. The pressurized water can come from tap water with water pressure. A control switch is provided on the water inlet pipe 3 or the water supply device of the pressurized water. The control member is communicatively connected to the control switch to control the water supply time and the water cut-off interval by controlling the opening and closing of the control switch. The control switch in the embodiment of the present application can be an electromagnetic switch. The control member controls the opening and closing of the electromagnetic switch, thereby controlling the first water supply time, the second water supply time, the third water supply time, the first water cut-off interval, and the second water cut-off interval of the water inlet pipe 3. In the embodiment of the present application, an opening switch is provided on the water tank 7 or the toilet body 6. Pressing the opening switch controls the control member to start working.

[0105] The present application also provides a flushing method for a toilet water supply device to control the toilet water supply device 600 in the above embodiments to flush, as Figure 23 shown, including the following steps:

[0106] S1: The control member controls the water supply time and the water cut-off interval of the water flow entering the control pipe 1 from the water inlet pipe 3, so as to drive the valve core 2 to move between the first control end 10 and the second control end 11 of the control pipe 1, and flush the toilet body 6.

[0107] In this step, the control member controls the water inlet pipe 3 to supply water to the control pipe 1 for the first time according to the water supply time. The valve core 2 is limited at the second control end 11 under the action of water pressure, as shown in Figure 3 and Figure 15 . At this time, the first water outlet 40 of the first water outlet pipe 4 discharges water to the cleaning water outlet 61 of the toilet body 6 for flushing. After the water inlet pipe 3 stops the first water supply, the valve core 2 is pulled up and limited at the first control end 10 under the action of the inertial pulling force of the water flow in the first water outlet pipe 4, as shown in Figure 4 , Figure 16 and Figure 17 . The water inlet pipe 3 starts to supply water to the control pipe 1 for the second time according to the water supply time during the water cut-off interval, so as to limit the valve core 2 at the first control end 10 by water pressure before the valve core 2 falls. At the same time, the second water outlet pipe 5 discharges water to siphon sewage at the siphon water outlet 62, as shown in Figure 5 and Figure 18 . After the water inlet pipe 3 stops the second water supply, the valve core 2 moves to the second control end 11, and a flushing of the toilet body 6 is completed, as shown in Figure 6 and Figure 19 .

[0108] As an optional embodiment, as shown in Figure 24 , the following steps are further included to realize the flushing of the toilet body 6:

[0109] S10: Set the first control end 10 above the second control end 11. The water supply time includes a first water supply time and a second water supply time, and the water cut-off interval includes a first water cut-off interval.

[0110] S11: In the initial state, the valve core 2 and the second control end 11 are on the same side of the side opening 12. The control member controls the water inlet pipe 3 to supply water to the control pipe 1 for the first time according to the first water supply time. The valve core 2 is limited at the second control end 11 under the action of water pressure. At this time, the flushing water flows out from the cleaning water outlet 61 of the toilet body 6 after passing through the water inlet pipe 3, the control pipe 1, and the first water outlet pipe 4, so as to clean the basin part 60 of the toilet body 6, as shown in Figure 3 and Figure 15 .

[0111] S12: The control member controls the water inlet pipe 3 to stop the first water supply. The valve core 2 is pulled up and limited at the first control end 10 under the action of the inertial pulling force of the water flow in the first water outlet pipe 4, as shown in Figure 4 , Figure 16 and Figure 17As shown in the figure. Specifically, at the moment when the water supply from the water inlet pipe 3 to the control pipe 1 stops for the first time, the water flow at the first water outlet 40 of the first water outlet pipe 4 pulls the valve core 2 by inertia force. Under the pulling action, the valve core 2 abuts against the first control end 10. At the same time, since the height of the first water outlet 40 is lower than that of the valve core 2, the inverted "U" - shaped structure of the first water outlet pipe 4 changes the gravity of water into the suction force on the valve core 2, so that the valve core 2 maintains its position against the first control end 10 unchanged. The first water supply time in this embodiment can be 3 s, or can be selected between 2 s and 10 s to achieve a better flushing effect on the basin part 60.

[0112] S13: After the control member controls the water inlet pipe 3 to stop water supply according to the first water - stop interval, it supplies water to the control pipe 1 for the second time according to the second water supply time, so as to press and limit the valve core 2 against the first control end 10 by water pressure before the valve core 2 falls. At this time, the second water outlet pipe 5 discharges water to siphon and discharge sewage at the siphon water outlet 62 of the toilet body 6. Specifically, at the moment when the water supply from the water inlet pipe 3 to the control pipe 1 stops for the second time, the water flow in the second water outlet pipe 5 pulls the valve core 2 downwards and limits it at the second control end 11 by inertia force. The water outlet of the second water outlet pipe 5 is lower than the valve core 2, changing the gravity of water into the suction force on the valve core 2, and jointly with the gravity of the valve core 2, maintaining the position of the valve core 2 unchanged. At the same time, air 9 gradually enters from the side of the first water outlet pipe 4, and the air 9 destroys the inertia force of the water in the second water outlet pipe 5 on the valve core 2. The second water supply time in this embodiment can be 4 s, or can be selected between 2 s and 10 s to achieve a better siphon sewage discharge effect. The first water - stop interval can be 0.5 s, or can be selected between 0.1 and 1.0, starting the second water supply before the air 9 gradually entering from the first water outlet 40 destroys the upward suction force of the water flow inertia force on the valve core 2 and causes the valve core 2 to fall.

[0113] S14: The control member controls the water inlet pipe 3 to stop the second water supply, and the valve core 2 moves to the second control end 11 under the action of the inertia force of the water flow in the second water outlet pipe 5 and its own gravity.

[0114] As an optional embodiment, as Figure 25 shown, it further includes the following steps:

[0115] S15: The set water supply time further includes a third water supply time, and the water - stop interval further includes a second water - stop interval.

[0116] S16: After the control member controls the water inlet pipe 3 to stop water supply according to the second water - stop interval, it supplies water to the control pipe 1 for the third time according to the third water supply time to clean the basin part 60 and form a water seal, as Figure 7 、 Figure 8 、 Figure 20 、 Figure 21 shown.

[0117] S17: After the control member controls the water inlet pipe 3 to stop the third water supply, the valve core 2 is limited at the second control end 11 to restore the initial state, as Figure 9 and Figure 22 shown. Specifically, during the third water supply, the valve core 2 is limited at the second control end 11 under the action of its own gravity and the attraction of the water flow in the second water outlet pipe 5, so that the water flow in the control pipe 1 enters the first water outlet pipe 4. When the third water supply stops and the inertia force of the water flow in the first water outlet pipe 4 is not sufficient to overcome the attraction of the water flow in the second water outlet pipe 5 to the valve core 2 and the gravity of the valve core 2 itself, the valve core 2 maintains the state of being limited at the second control end 11.

[0118] According to needs, the above technical solutions can be combined to achieve the best technical effect.

[0119] The above are only the principles and preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, based on the principle of the present invention, several other variations can also be made, which should also be regarded as the protection scope of the present invention.
