[0041] Please refer to Figure 1 , Figure 1 It is a schematic structural diagram of the cross-sectional view of the flushing device provided by the present application.

[0042] The present application provides a flushing device. AsFigure 1 As shown in Figure 2 Figure 2 , the flushing device of this embodiment includes: a pilot valve 10, an opening and closing assembly 20, and a water distribution valve 30. An inlet 61 is provided on the pilot valve 10. The opening and closing assembly 20 is arranged inside the pilot valve 10, and the opening and closing of the inlet 61 is controlled by the opening and closing assembly 20. A receiving space 31 communicating with the pilot valve 10 is formed inside the water distribution valve 30. A manual flushing assembly 50 and an electric flushing assembly 40 are arranged inside the receiving space 31. The manual flushing assembly 50 and the electric flushing assembly 40 are connected to the opening and closing assembly 20 and control the state of the opening and closing assembly 20. The water distribution valve 30 is provided with a first water outlet 62 and a second water outlet 63 communicating with the receiving space 31. Among them, the manual flushing assembly 50 and the electric flushing assembly 40 can move inside the receiving space 31 to drive the opening and closing assembly 20 to open or close the inlet 61, and control the opening and closing states of the first water outlet 62 and the second water outlet 63.

[0043] In an optional embodiment, the opening and closing assembly 20 is arranged inside the pilot valve 10. An inlet 61 is opened on the pilot valve 10, and a water inlet pipe is connected to the inlet 61 for supplying water to the pilot valve 10. Specifically, the opening and closing assembly 20 is used to control the opening and closing of the inlet 61, so as to control the on-off of the water inlet of the pilot valve 10.

[0044] Among them, a receiving space 31 is formed inside the water distribution valve 30, and this receiving space 31 is communicated with the pilot valve 10. After the opening and closing assembly 20 opens the inlet 61 of the pilot valve 10, the pilot valve 10 can supply water to the water distribution valve 30. After the opening and closing assembly 20 controls the inlet 61 of the pilot valve 10 to close, the pilot valve 10 stops supplying water to the water distribution valve 30.

[0045] In some embodiments, a manual flushing assembly 50 and an electric flushing assembly 40 are arranged inside the receiving space 31 of the water distribution valve 30. The manual flushing assembly 50 and the electric flushing assembly 40 are connected to the opening and closing assembly 20 inside the pilot valve 10. That is, the working state of the opening and closing assembly 20 can be controlled by the manual flushing assembly 50 and the electric flushing assembly 40. Among them, the water distribution valve 30 is provided with a first water outlet 62 and a second water outlet 63 communicating with the receiving space 31. After the pilot valve 10 pumps water to the water distribution valve 30, the first water outlet 62 and the second water outlet 63 can be split, and the liquid is discharged through the first water outlet 62 and the second water outlet 63.

[0046] In some embodiments, the liquid in the accommodating space 31 can be discharged through the first water outlet 62 and the second water outlet 63 respectively, or can be discharged separately through the first water outlet 62 and the second water outlet 63. Specifically, the manual flushing assembly 50 and the electric flushing assembly 40 can rotate within the accommodating space 31 of the water distribution valve 30, so as to control the opening and closing of the first water outlet 62 and the second water outlet 63. Among them, the manual flushing assembly 50 and the electric flushing assembly 40 move within the accommodating space 31, which can drive the state of the opening and closing assembly 20 in the pilot valve 10, and control the on-off of the water inlet 61 of the pilot valve 10 through the opening and closing assembly 20.

[0047] Among them, the water distribution valve 30 can be cylindrical, that is, the inner side wall of the accommodating space 31 of the water distribution valve 30 is arc-shaped, and the manual flushing assembly 50 and the electric flushing assembly 40 can rotate relative to each other within the accommodating space 31. When the manual flushing assembly 50 and the electric flushing assembly 40 rotate within the accommodating space 31, they can drive the opening and closing assembly 20 to move to control the on-off state of the water inlet 61 of the pilot valve 10. And when the manual flushing assembly 50 and the electric flushing assembly 40 rotate within the accommodating space 31, the manual flushing assembly 50 and the electric flushing assembly 40 can block the first water outlet 62 or the second water outlet 63, so as to divert the liquid. Among them, the manual flushing assembly 50 and the electric flushing assembly 40 can rotate within the accommodating space 31 respectively, that is, the manual flushing assembly 50 and the electric flushing assembly 40 can respectively control the opening or closing of the opening and closing assembly 20 of the water inlet 61, and can also respectively control the on-off state of the first water outlet 62 and the second water outlet 63.

[0048] In some embodiments, the water distribution valve 30 and the pilot valve 10 can be integrally arranged, that is, the pilot valve 10 and the water distribution valve 30 can share a common housing. By integrally arranging the water distribution valve 30 and the pilot valve 10, the overall size of the flushing device can be effectively reduced, which is beneficial to the installation of the flushing device in the whole machine and effectively improves the layout of the flushing device in the whole machine.

[0049] In an application scenario, the flushing device can be arranged in a smart toilet, that is, the electric flushing assembly 40 in the flushing device can be connected to household electricity. When the smart toilet is in use, the electric flushing assembly 40 can be driven to rotate within the accommodating space 31 of the water distribution valve 30. When the electric flushing assembly 40 rotates, it can drive the opening and closing assembly 20 to move, so that the water inlet 61 of the pilot valve 10 is opened, so that the water flow enters the water distribution valve 30 through the pilot valve 10. And when the electric flushing assembly 40 rotates within the accommodating space 31, it can block the first water inlet 62 or the second water inlet 63, so that the water flow is discharged through the first water outlet 62 and / or the second water outlet 63.

[0050] Further, when using this intelligent toilet, power outages and other situations will inevitably occur. At this time, the electric flushing assembly 40 cannot work properly. The user can manually control the manual flushing assembly 50 to rotate within the accommodating space 31 of the water distribution valve 30. When the manual flushing assembly 50 rotates within the accommodating space 31, the manual flushing assembly 50 can drive the opening and closing assembly 20 to open, so that the water inlet 61 of the pilot valve 10 is opened, allowing water to enter the water distribution valve 30 through the pilot valve 10. Moreover, when the manual flushing assembly 50 rotates within the accommodating space 31, it can block the first water inlet 61 or the second water inlet 61, so that the water flows out through the first water outlet 62 and / or the second water outlet 63. That is, when the flushing device loses power, the water distribution valve 30 can be controlled to drain water through the manual flushing assembly 50, without the need to drive the water distribution valve 30 to drain water by the electric flushing assembly 40 powered by electricity. That is, the flushing device does not require an external power supply. In the event of a power outage or other situations, the flushing device can be controlled to work through mechanical operation, that is, the flushing device can be normally used when the power is off.

[0051] In the above embodiment, by providing the opening and closing assembly 20 to control the opening and closing of the water inlet 61 of the pilot valve 10, the water distribution valve 30 is connected to the pilot valve 10, and a manual flushing assembly 50 and an electric flushing assembly 40 are provided within the water distribution valve 30. When the power is on, the electric flushing assembly 40 can control the flushing device to drain water. When the power is off, the manual flushing assembly 50 can be controlled to move within the water distribution valve 30 through mechanical operation to control the flushing device to drain water, which can ensure the normal use of the flushing device when the power is off, and does not require an external power supply, which can effectively reduce costs.

[0052] In an alternative embodiment, as Figure 2 shown, the pilot valve 10 includes a housing cover 11, a pilot bracket 12, and a pilot membrane 13. The housing cover 11 is provided at one end of the pilot valve 10 away from the water distribution valve 30. The pilot bracket 12 is provided within the housing cover 11, and the pilot membrane 13 is clamped and fixed by the housing cover 11 and the pilot bracket 12. A pilot hole 14 is provided on the end face of the housing cover 11 close to the water distribution valve 30. The axis of the pilot hole 14 is parallel to the axis of the housing cover 11, and the pilot hole 14 is provided at the edge of one end of the housing cover 11. The opening and closing assembly 20 is provided in contact with the pilot hole 14.

[0053] Among them, when the flushing device is not in use, that is, when it is not necessary to pump water through the pilot valve 10 and the water distribution valve 30, the opening and closing assembly 20 can be in contact with the pilot hole 14, that is, the pilot hole 14 is blocked by the opening and closing assembly 20, thereby closing the water inlet 61 of the pilot valve 10. When the flushing device needs to be used, that is, when it is necessary to open the pilot valve 10, the opening and closing assembly can be controlled to move away from the pilot hole 14, and the pilot hole 14 is opened, thereby opening the water inlet 61 of the pilot valve 10, so that the water is transmitted into the water distribution valve 30 through the pilot valve 10.

[0054] In this embodiment, as Figure 3 shown, the opening and closing assembly 20 includes a piston rod 21, a rubber member 23, and a reset member 22. The reset member 22 is sleeved on the piston rod 21. One end of the reset member 22 is connected to the inner side wall of the pilot valve 10 away from the water distribution valve 30, and the other end is connected to one end of the piston rod 21 close to the pilot valve 10. The rubber member 23 is arranged at one end of the piston rod 21 close to the pilot. One end of the piston rod 21 abuts against the pilot hole 14, and the other end abuts against and is inserted into the manual flushing assembly 50 and the electric flushing assembly 40.

[0055] In some embodiments, as Figure 4 shown, a slide rail 211 is arranged on the piston rod 21 along the axial direction of the piston rod 21, and a first column 212 and a second column 213 are arranged on the opposite side surfaces of one end of the piston rod 21 close to the water distribution valve 30. Among them, the first column 212 can be inserted into the electric flushing assembly 40, and the second column 213 can be inserted into the manual flushing assembly 50. That is, when the electric flushing assembly 40 or the manual flushing assembly 50 rotates in the accommodation space 31 of the water distribution valve 30, it can drive the piston rod 21 to slide along the axial direction of the pilot hole 14, so as to control the closing and opening of the water inlet 61 of the pilot valve 10 by blocking or disengaging from the pilot hole 14. And the slide rail 211 can cooperate with the inner side wall of the water distribution valve 30, so as to prevent the piston rod 21 from rotating when sliding along the axial direction of the pilot hole 14, resulting in the failure of the cooperation with the electric flushing assembly 40 and the manual flushing assembly 50.

[0056] Among them, when using the flushing device, the manual flushing assembly 50 or the electric flushing assembly 40 can be controlled to rotate in the water distribution valve 30, so as to drive the piston rod 21 away from the pilot hole 14. The pilot hole 14 is opened so that the water inlet 61 of the pilot valve 10 is opened, so that the pilot valve 10 supplies water to the water distribution valve 30 and discharges through the first water outlet 62 and / or the second water outlet 63. When the flushing device stops being used, the flushing assembly or the electric flushing assembly 40 can be reversed, and under the action of the reset member 22, the piston rod 21 is controlled to abut against the pilot hole 14, so as to close the water inlet 61 of the pilot valve 10.

[0057] In some embodiments, as Figure 3As shown in the figure, a rubber part 23 is provided at one end of the piston rod 21 close to the pilot hole 14. Under the action of the reset part 22, the pilot hole 14 can be blocked by the rubber part 23. Among them, the diameter of the pilot hole 14 is 0.8mm - 1.2mm. According to the pressure formula F = P*S, where F is the pressure, S is the force-bearing area, and P is the pressure. That is, the smaller the force-bearing area of the pilot hole 14, the smaller the pressure of the water flow on the rubber part 23, and correspondingly, the smaller the elastic force required for the reset part 22. Therefore, when the diameter of the pilot hole 14 is within the above range, the effect of controlling the opening and closing of the water inlet 61 of the pilot valve 10 through the opening and closing assembly 20 is effectively ensured.

[0058] In some embodiments, as Figure 2 shown, the electric flushing assembly 40 includes a driving part 41, a first end cover 42 and a first valve core 43. The first end cover 42 is arranged at one end of the water distribution valve 30 to form a receiving space 31. The driving part is arranged at the end of the first end cover 42 away from the receiving space 31. The first valve core 43 is arranged in the receiving space 31 and is connected to the driving part 41. The other end of the first valve core 43 abuts against the opening and closing assembly 20, and the first valve core 43 rotates relative to the receiving space 31. Among them, the axial direction of the first valve core 43 is perpendicular to the axial direction of the opening and closing assembly 20. When the first valve core 43 rotates, it drives the opening and closing assembly 20 to open or close the pilot valve 10.

[0059] Among them, the driving part 41 is used to connect to a power source, such as a household power source. The driving part 41 can be a motor, that is, the driving part 41 can drive the first valve core 43 to rotate in the receiving space 31 of the water distribution valve 30. In other embodiments, the driving part 41 can also be other power-providing devices, such as a cylinder, etc., as long as the first valve core 43 can be driven to rotate in the receiving space 31 through other linkage components. Specifically, the present application does not make specific limitations here.

[0060] In some embodiments, a first end cover 42 is arranged at one end of the water distribution valve 30. The first end cover 42 is detachably connected to the water distribution valve 30 to form a receiving space 31. The first valve core 43 passes through the first end cover 42 and is connected to the driving part 41. Among them, the rotation axis of the driving part 41 is the rotation axis of the first valve core 43. That is, one end of the first valve core 43 is connected to the driving part 41, and the other end of the first valve core 43 is connected to the opening and closing assembly 20.

[0061] When the flushing device needs to flush, the driving member 41 drives the first valve core 43 to rotate within the accommodating space 31. When the first valve core 43 rotates, the first valve core 43 can drive the opening and closing assembly 20 to move away from the pilot hole 14 along the axis direction of the pilot hole 14, so that the pilot hole 14 is opened. After the pilot hole 14 is opened, the water inlet 61 of the pilot valve 10 can be opened. After the water inlet 61 is opened, water can enter the diverter valve 30 through the pilot valve 10. After entering the accommodating space 31 of the diverter valve 30, it can be discharged through the first water outlet 62 and / or the second water outlet 63.

[0062] In an alternative embodiment, as shown in Figure 5 a first limiting member (not shown in the figure) is provided on the end face of the first end cover 42 close to the first valve core 43, and a second limiting member 438 is provided at one end of the first valve core 43 close to the first end cover 42. The first limiting member and the second limiting member 438 can be relatively matched. When the driving member 41 drives the first valve core 43 to rotate, the rotation angle of the first valve core 43 can be controlled through the cooperation of the first limiting member and the second limiting member 438, so as to avoid the situation of excessive rotation angle. Among them, the first limiting member and the second limiting member 438 can be convex structures or other structures, and the present application does not make specific limitations here.

[0063] In some embodiments, as shown in Figure 6 a first baffle 44 is provided on the first valve core 43. The first baffle 44 is attached to the inner side wall of the diverter valve 30. A pressure relief hole 442 is provided at the position of the first baffle 44 corresponding to the first water outlet 62. The pressure relief hole 442 is used to relieve the pressure of the diverter valve 30 when the first baffle 44 corresponds to the first water outlet 62. Among them, the first baffle 44 is set to be arc-shaped, that is, the first baffle 44 can completely fit the inner side wall of the diverter valve 30. When the driving member 41 drives the first valve core 43 to rotate, the first baffle 44 can be rotated within the accommodating space 31, so that the first baffle 44 can block the first water outlet 62 and the second water outlet 63 respectively, and thus the water flow entering the diverter valve 30 is diverted through the first baffle 44.

[0064] When the first spool 43 rotates within the accommodation space 31, the first spool 43 can drive the opening and closing assembly 20 away from the pilot hole 14, thereby opening the water inlet 61 of the pilot valve 10, so that the pilot valve 10 supplies water to the water distribution valve 30. When the first spool 43 rotates, the first baffle 44 rotates accordingly. When the first baffle 44 rotates, it can block the first water outlet 62, so that the water flow is discharged through the second water outlet 63. Driven by the driving member 41, the first spool 43 continues to rotate, and the first baffle 44 moves away from the first water outlet 62. At this time, the first baffle 44 can block part of the first water outlet 62 and the second water outlet 63, and at this time, the water flow can be discharged through the first water outlet 62 and the second water outlet 63. When the first baffle 44 continues to rotate, the first baffle 44 completely disengages from the first water outlet 62 and completely blocks the second water outlet 63. At this time, the water flow can be discharged through the first water outlet 62.

[0065] Further, after the first spool 43 rotates and the flushing device completes the diversion of the water flow, the driving member 41 can rotate in the reverse direction, thereby driving the first spool 43 and the first baffle 44 to rotate and return to the initial position. At this time, under the action of the reset member 22, the opening and closing assembly 20 can completely block the pilot hole 14, so that the water inlet 61 of the pilot valve 10 is closed, so that the pilot valve 10 stops supplying water to the water distribution valve 30.

[0066] In some embodiments, when the first spool 43 is in the initial position, that is, when the pilot valve 10 and the water distribution valve 30 are not working, the first baffle 44 can block part of the first water outlet 62. Specifically, the present application does not make specific limitations here.

[0067] Among them, a pressure relief hole 442 is provided at the position of the first baffle 44 corresponding to the first water outlet 62. That is, when the first baffle 44 completely blocks the first water outlet 62, the water flow in the accommodation space 31 can be discharged through the pressure relief hole 442 and the first water outlet 62 corresponding to the pressure relief hole 442, so as to avoid excessive water pressure in the accommodation space 31 of the water distribution valve 30 and damage the flushing device. For example, when the flushing device is arranged in a smart toilet, that is, when the first water outlet 62 corresponds to the bottom flushing port of the smart toilet, that is, when the pressure relief hole 442 corresponds to the bottom flushing port, the flushing device is relieved of pressure through the pressure relief hole 442 and the bottom flushing port.

[0068] In a specific application scenario, when the flushing device is applied to a smart toilet, the first water outlet 62 is the bottom flushing port of the smart toilet, and the second water outlet 63 is the side punching hole. That is, the driving member 41 can drive the first valve core 43 to rotate, so as to separately control the closing of the bottom flushing port and the side flushing port, and flush the smart toilet. When the first baffle 44 completely blocks the second water outlet 63, that is, the side flushing port, at this time, the smart toilet has completed side flushing and bottom flushing. The driving member 41 can drive the first baffle 44 to rotate in the reverse direction and open the second water outlet 63 to replenish water to the ceramic base in the smart toilet.

[0069] In some embodiments, as Figure 5 shown, the first valve core 43 includes a first rotating shaft 431 and a first turntable 432. One end of the first rotating shaft 431 is connected to the driving member 41, and the other end is connected to the first turntable 432. The first baffle 44 is arranged on the side wall of the first rotating shaft 431. The edge of the first turntable 432 is connected to the opening and closing assembly 20. The first turntable 432 is in an irregular semi-circular arc shape, and the opening and closing assembly 20 is inserted into the first turntable 432. When flushing is required, the driving member 41 drives the first rotating shaft 431 to rotate, thereby driving the first turntable 432 to rotate. The opening and closing assembly 20 is inserted into the irregular semi-circular arc-shaped first turntable 432. When the first turntable 432 rotates, the first turntable 432 drives the opening and closing assembly 20 to move along the axis direction of the pilot hole 14, so as to control the on-off of the water inlet 61 of the pilot valve 10 and the opening and closing states of the first water outlet 62 and the second water outlet 63.

[0070] Specifically, a first arc protrusion 433 and a second arc protrusion 435 are arranged at the edge position of the first turntable 432 away from the second end cover 52. The first arc protrusion 433 and the second arc protrusion 435 are concentrically arranged. The diameter of the first arc protrusion 433 is larger than the diameter of the second arc protrusion 435. The first arc protrusion 433 and the second arc protrusion 435 are connected by a first linear protrusion 434. That is, the piston rod 21 of the opening and closing assembly 20 is inserted into the first turntable 432, and the first column 212 on the piston rod 21 abuts against the inner side walls of the first arc protrusion 433, the second arc protrusion 435 and the first linear protrusion 434. Among them, when the first column 212 abuts against the inner side wall of the first arc protrusion 433, at this time, the other end of the opening and closing assembly 20 abuts against the pilot hole 14, thereby blocking the pilot hole 14. At this time, the first valve core 43 is in the initial state. That is, when the first column 212 of the piston rod 21 is on the inner side wall of the first arc protrusion 433, the water inlet 61 of the pilot valve 10 is closed. When the first column 212 of the piston rod 21 is on the inner side wall of the second arc protrusion 435, the water inlet 61 of the pilot valve 10 is opened.

[0071] In this embodiment, when the driving member 41 drives the first turntable 432 to rotate through the first rotating shaft 431, the opening and closing assembly 20 has four working states:

[0072] First, the driving member 41 drives the first turntable 432 to rotate, and the first column 212 on the piston rod 21 slides on the inner side wall of the first arc-shaped protrusion 433. At this time, the rubber member 23 on the piston rod 21 abuts against the pilot hole 14, and the water inlet 61 of the pilot valve 10 is in a closed state.

[0073] Second, the first turntable 432 continues to rotate, and the first column 212 on the piston rod 21 slides along the inner side wall of the first arc-shaped protrusion 433 to the inner side wall of the first linear protrusion 434, and the reset member 22 of the opening and closing assembly 20 is compressed. At this time, the rubber member 23 on the piston rod 21 begins to gradually move away from the pilot hole 14, and the water inlet 61 of the pilot valve 10 gradually opens.

[0074] Third, the first column 212 of the piston rod 21 slides from the inner side wall of the first linear protrusion 434 to the inner side wall of the second arc-shaped protrusion 435, and the reset member 22 of the opening and closing assembly 20 is compressed. At this time, the rubber member 23 on the piston rod 21 completely disengages from the pilot hole 14, the water inlet 61 of the pilot valve 10 is in an open state, the pilot valve 10 supplies water to the water distribution valve 30, and discharges through the first water outlet 62 and / or the second water outlet 63.

[0075] Fourth, after the water pumping is completed, the driving member 41 drives the first turntable 432 to rotate in the reverse direction. Under the action of the reset member 22, the first column 212 of the piston rod 21 slides from the inner side wall of the second arc-shaped protrusion 435 and the inner side wall of the first linear segment to the inner side wall of the first arc segment. At this time, the reset member 22 gradually resets, driving the piston rod 21 to gradually move towards the pilot hole 14 until the rubber member 23 on the piston rod 21 completely abuts against the pilot hole 14. At this time, the water inlet 61 of the pilot valve 10 is closed, and the water supply to the water distribution valve 30 stops.

[0076] In some embodiments, a buckle member 436 is provided on the side wall of the first rotating shaft 431, and a clamping groove 437 is formed in the buckle member 436. A clamping member 441 is provided on the first retaining piece 44, and the clamping member 441 is clamped inside the clamping groove 437. That is, the first retaining piece 44 is detachably arranged on the first rotating shaft 431. In other embodiments, the first retaining piece 44 can be integrally arranged with the first rotating shaft 431, and the present application does not make specific limitations here.

[0077] In an alternative embodiment, the manual flushing assembly 50 includes an operating lever 51, a second end cap 52, and a second valve core 53. The second end cap 52 is disposed at one end of the water distribution valve 30 away from the first end cap 42. The operating lever 51 is inserted into the second end cap 52 and at least partially exposed from the second end cap 52. The second valve core 53 is disposed in the accommodating space 31 and connected to the operating lever 51. The other end of the second valve core 53 abuts against the opening and closing assembly 20. The second valve core 53 is coaxially disposed with the first valve core 43. When the second valve core 53 rotates, it drives the opening and closing assembly 20 to open or close the pilot valve 10.

[0078] Among them, in the case of power failure, that is, when the electric flushing assembly 40 cannot work properly, when the user needs to flush, the corresponding flushing can be completed through the manual flushing assembly 50. The operating lever 51 of the manual flushing assembly 50 penetrates the second end cap 52 and is connected to the second valve core 53. When flushing, the operating lever 51 can be toggled in a mechanical operation manner, so as to drive the second valve core 53 to rotate in the accommodating space 31 of the water distribution valve 30, so as to drive the opening and closing assembly 20 to move along the axis direction of the pilot hole 14 through the second valve core 53, thereby opening the water inlet 61 of the pilot valve 10, enabling the pilot valve 10 to supply water to the water distribution valve 30, and discharging through the first water outlet 62 and / or the second water outlet 63.

[0079] In some embodiments, in combination with Figure 7 and Figure 8 as shown, the second valve core 53 includes a second rotating shaft 531. A first hole 537 is provided on one side of the second rotating shaft 531 close to the first valve core 43. The first hole 537 is cooperatively connected with the first rotating shaft 431 of the first valve core 43, that is, the first rotating shaft 431 of the first valve core 43 can be movably connected in the first hole 537, that is, the first valve core 43 is coaxially disposed with the second valve core 53. A second hole 538 is provided at the end of the second rotating shaft 531 away from the first valve core 43. The second hole 538 is used to connect with the operating lever 51, so as to facilitate controlling the rotation of the second valve core 53 through the operating lever 51.

[0080] In some embodiments, a second retaining piece 532 and a second turntable 533 are provided at the edge position of the second valve core 53. The second retaining piece 532 is attached to the inner side wall of the water distribution valve 30, and the second turntable 533 is in an irregular semi-circular arc shape. The opening and closing assembly 20 is inserted inside the second turntable 533. The second valve core 53 is arranged in the accommodation space 31 of the water distribution valve 30. A second turntable 533 is provided at the edge position of the second valve core 53, and a second retaining piece 532 is provided at the edge position opposite to the second turntable 533, that is, the second retaining piece 532 is close to the first valve core 43. When flushing is required, the operating rod 51 can be waved to rotate around the axis of the second rotating shaft 531, thereby driving the second valve core 53 to rotate in the accommodation space 31. The opening and closing assembly 20 is inserted inside the edge position of the second turntable 533. When the second turntable 533 rotates, the second turntable 533 drives the opening and closing assembly 20 to move, thereby controlling the on-off of the water inlet 61 of the pilot valve 10 and the opening and closing states of the first water outlet 62 and the second water outlet 63.

[0081] Wherein, the first valve core 43 and the second valve core 53 are arranged in the accommodation space 31 of the water distribution valve 30, and the first rotating shaft 431 of the first valve core 43 and the second rotating shaft 531 of the second valve core 53 are coaxially arranged, and the first rotating shaft 431 and the second rotating shaft 531 are movably arranged, that is, the first valve core 43 and the second valve core 53 can rotate independently in the accommodation space 31 of the water distribution valve 30, and the first turntable 432 of the first valve core 43 and the second turntable 533 of the second valve core 53 are oppositely arranged on the opposite sides of the opening and closing assembly 20. Specifically, the first upright column 212 on the piston rod 21 is inserted into the inner side wall of the first turntable 432, and the second upright column 213 is inserted into the inner side wall of the second turntable 533, that is, when the first turntable 432 and the second turntable 533 rotate independently, they can drive the piston rod 21 to move separately. And the first turntable 432 and the second turntable 533 are oppositely arranged and have matching shapes, which can effectively avoid the interference of the second turntable 533 or the first turntable 432 on the opening and closing assembly 20 when the first turntable 432 or the second turntable 533 rotates independently.

[0082] Specifically, the second turntable 533 is provided with a third arc protrusion 534 and a fourth arc protrusion 536 near the edge position of the first valve core 43. The third arc protrusion 534 and the fourth arc protrusion 536 are concentrically arranged. The diameter of the third arc protrusion 534 is larger than that of the fourth arc protrusion 536. The third arc protrusion 534 and the fourth arc protrusion 536 are connected by a second straight protrusion 535. That is, the piston rod 21 of the opening and closing assembly 20 is inserted into the second turntable 533, and the second column 213 on the piston rod 21 abuts against the inner side walls of the third arc protrusion 534, the fourth arc protrusion 536, and the second straight protrusion 535. When the second column 213 abuts against the inner side wall of the third arc protrusion 534, the rubber part 23 on the piston rod 21 abuts against the pilot hole 14 at this time, thereby blocking the pilot hole 14. When the second column 213 abuts against the inner side wall of the fourth arc protrusion 536, the piston rod 21 is separated from the pilot hole 14 at this time, so that the pilot valve 10 is opened and water is supplied to the water distribution valve 30.

[0083] Among them, when the operating rod 51 drives the second rotating shaft 531 to rotate the second turntable 533, the opening and closing assembly 20 has four working states, which are specifically similar to the working states of the above-mentioned first turntable 432 and will not be elaborated here.

[0084] In some embodiments, in combination Figure 12 with Figure 13 as shown, the diameter of the third arc protrusion 534 of the second turntable 533 is the same as the diameter of the first arc protrusion 433 of the first turntable 432, and the diameter of the fourth arc protrusion 536 of the second turntable 533 is the same as the diameter of the second arc protrusion 435. That is, when the first valve core 43 and the second valve core 53 are arranged in the water distribution valve 30, the first valve core 43 and the second valve core 53 can be coaxially arranged.

[0085] In some embodiments, as Figure 9 shown, the operating rod 51 includes a handle 511 and a rotating part 512. The handle 511 is connected to the rotating part 512 and exposed at the second end cover 52. The rotating part 512 is formed with an annular protrusion 513. The annular protrusion 513 is arranged between the second end cover 52 and the second valve core 53 to clamp and fix the operating rod 51. Among them, when the second end cover 52 is arranged on the water distribution valve 30, the operating rod 51 can penetrate through the second end cover 52 and be connected to the second valve core 53, and the annular protrusion 513 on the rotating part 512 is clamped and fixed between the second end cover 52 and the second valve core 53.

[0086] In some embodiments, when controlling the flushing device to flush water through the manual flushing assembly 50, the handle 511 on the operating lever 51 can be toggled to drive the rotating member 512 to rotate, thereby driving the second valve core 53 to rotate within the accommodating space 31 of the water distribution valve 30, thus controlling the pilot valve 10 to open and transmitting the water flow into the water distribution valve 30 and through the first water outlet 62 and / or the second water outlet 63.

[0087] In some embodiments, as Figure 15 shown, the manual flushing assembly 50 further includes a torsion spring 54. A notch 516 is provided at one end of the rotating member 512 away from the handle 511. In combination with Figure 16 shown, one end of the torsion spring 54 is clamped on the second valve core 53. In combination with Figure 10 described, the other end is clamped within the notch 516. When the operating lever 51 is arranged on the water distribution valve 30, one end of the torsion spring 54 can be fixed within the notch 516 on the rotating member 512, and the other end is fixed on the water distribution valve 30. And a socket connector 539 is arranged in the second hole position 538 on the second rotating shaft 531, and the socket connector 539 can be clamped in the notch 516, so that by rotating the operating lever 51, the second valve core 53 can be driven to rotate within the accommodating space 31 of the water distribution valve 30.

[0088] In this embodiment, when the flushing device does not need to pump water, that is, when the opening and closing assembly 20 abuts against the pilot hole 14, the torsion spring 54 can provide corresponding elastic force to the second valve core 53 to prevent the operating lever 51 from rotating, so as to drive the second valve core 53 to rotate within the water distribution valve 30, thereby causing the opening and closing assembly 20 to separate from the pilot hole 14.

[0089] In some embodiments, the operating lever 51 further includes a connecting rod 514. One end of the connecting rod 514 is connected to the handle 511, and the other end is connected to the rotating member 512. A groove 515 is provided at one end of the connecting rod 514 close to the second end cover 52, and a boss 522 cooperating with the groove 515 is provided on the second end cover 52. Specifically, a groove 515 is provided on the connecting rod 514, and a boss 522 is provided on the end face of the second end cover 52 away from the second valve core 53. When the handle 511 is toggled, the handle 511 drives the connecting rod 514 to rotate. When the groove 515 on the connecting rod 514 rotates to correspond to the boss 522 of the second end cover 52, a sound will be generated to prompt the rotation angle. For example, when the groove 515 is clamped with the boss 522 and a sound is generated, it can be prompted that water is draining at the first water outlet 62 or the second water outlet 63 of the water distribution valve 30. The boss 522 can be set in a semi-circular arc shape to reduce the friction when the groove 515 cooperates with the boss 522. The specific structure is set according to needs, and the present application does not make specific limitations here.

[0090] In some embodiments, as Figure 11As shown, on the end face of the second end cap 52 away from the second valve core 53, two third limiting members 521 are provided. Combining Figure 14 As shown, the third limiting members 521 can cooperate with the connecting rod 514 of the operating rod 51, so as to limit the rotation angle of the operating rod 51 through the two third limiting members 521.

[0091] In some embodiments, the initial position of the second valve core 53 arranged in the water distribution valve 30 is the position where the opening and closing assembly 20 abuts against the pilot hole 14, that is, the position where the pilot valve 10 is closed. At this time, the second baffle 532 of the second valve core 53 is far away from the first water outlet 62 and the second water outlet 63, that is, the second baffle 532 does not block the first water outlet 62 and the second water outlet 63.

[0092] In a specific application scenario, when powered on, the first valve core 43 can be driven to rotate in the water distribution valve 30 through the driving member 41, so that the flushing device completes the corresponding pumping work. When powered off, the operating rod 51 can be toggled, so that the second valve core 53 rotates in the water distribution valve 30, so that the flushing device completes the corresponding pumping work. And since the first turntable 432 of the first valve core 43 and the second turntable 533 of the second valve core 53 are oppositely arranged on both sides of the opening and closing assembly 20, when the electric flushing assembly 40 performs the pumping operation, it will not interfere with the second valve core 53. Correspondingly, when the manual flushing assembly 50 performs the pumping operation, it will not interfere with the first valve core 43.

[0093] In some embodiments, as Figure 2 As shown, an air isolation valve 70 is provided on the pilot valve 10, and the on-off state of the air isolation valve 70 is opposite to the on-off state of the pilot valve 10. That is, when the pilot valve 10 is opened, the water flow in the pilot valve 10 can abut upward against the isolation valve core 71 inside the air valve, so as to achieve a sealing effect. When the pilot valve 10 is closed, the isolation valve core 71 of the air isolation valve 70 drops due to the lack of water flow abutment, so that the pilot valve 10 communicates with the atmosphere of the water distribution valve 30, thus effectively avoiding the occurrence of backflow.

[0094] The present application also provides an intelligent toilet, as Figure 18 As shown, the intelligent toilet 90 includes: a flushing device, and the flushing device is the flushing device of any of the above embodiments.

[0095] In some embodiments, combining Figure 19 with Figure 20As shown in the figure, the intelligent toilet 90 includes a housing 91. A support member 911 is provided on the housing 91. A support hole 912 is formed in the support member 911, and a pull rod 80 is movably connected in the support hole 912. One end of the pull rod 80 is movably connected to a handle 511 on an operating rod 51, and the other end is provided with a pull ring 81. At least a part of the pull ring 81 is exposed outside the housing 91. Specifically, a sliding member 82 is provided at one end of the pull rod 80, and a chute (not shown in the figure) is provided inside the handle 511. The sliding member 82 of the pull rod 80 slides inside the chute of the handle 511. That is, when the pull rod 80 is pulled, the sliding member 82 on the pull rod 80 can slide relatively inside the chute of the handle 511, thus avoiding interference or jamming when the pull rod 80 is pulled.

[0096] In some embodiments, a receiving cavity 93 for receiving the pull ring 81 is provided on the housing 91, and a decorative cover 92 is provided outside the receiving cavity 93. That is, when the pull rod 80 is not in use, the pull ring 81 on the pull rod 80 can be placed inside the receiving cavity 93 to improve the aesthetic appearance of the intelligent toilet 90.

[0097] In this embodiment, a through hole (not shown in the figure) with a diameter smaller than the size of the pull ring 81 is formed on the inner side wall of the receiving cavity 93 of the housing 91, so that the pull rod 80 can be limited by the through hole to avoid over-limited movement.

[0098] In a specific application scenario, when the intelligent toilet 90 needs to be used in a power-off situation, the pull ring 81 on the pull rod 80 can be pulled, so that the pull rod 80 pulls the operating rod 51 to rotate, so that the flushing device starts to pump water, and the intelligent toilet 90 completes the corresponding bottom flushing and side flushing. After the bottom flushing and side flushing are completed, the pull rod 80 can be pushed into the intelligent toilet 90 to push the operating rod 51 to move in the reverse direction, so that the second valve core 53 returns to the initial position.

[0099] In this embodiment, when using the manual flushing component 50 to flush the toilet, it can be divided into four states:

[0100] First, as Figure 21 shown, by pulling the pull rod 80 and driving the handle 511 on the operating rod 51 to rotate, the rotating member 512 rotates and drives the second valve core 53 to rotate in the accommodating space 31 of the water distribution valve 30. The second valve core 53 rotates, so that the opening and closing component 20 moves away from the pilot hole 14 along the axis direction of the pilot hole 14, and the water inlet 61 of the pilot valve 10 is opened to supply water to the water distribution valve 30. At this time, the groove 515 on the connecting rod 514 is engaged with the boss 522 on the second end cover 52, thus making a "click" sound. At this time, the second flap 532 of the second valve core 53 does not block the first water outlet 62 and the second water outlet 63, so that the water flow in the water distribution valve 30 is discharged through the first water outlet 62 and the second water outlet 63.

[0101] In this embodiment, when the flushing device is arranged inside the intelligent toilet 90, the first water outlet 62 is the bottom flushing port, and the second water outlet 63 is the side flushing port. That is, when the groove 515 on the connecting rod 514 is clamped with the boss 522 on the second end cover 52, the intelligent toilet 90 performs the flow splitting function of bottom flushing and side flushing at this time.

[0102] Second, as Figure 22 shown in Figure 17 Continue to pull the pull rod 80 to drive the handle 511, so that the rotating part 512 continues to drive the second valve core 53 to rotate, and the opening and closing assembly 20 continuously disengages from the pilot hole 14. The groove 515 on the connecting rod 514 disengages from the boss 522 on the second end cover 52, and the connecting rod 514 abuts against the third limiting part 521 on the second end cover 52. At this time, the second baffle 532 of the second valve core 53 completely blocks the second water outlet 63, that is, the water flow in the water distribution valve 30 is discharged through the first water outlet 62.

[0103] In this embodiment, the flushing device is arranged inside the intelligent toilet 90, and the second water outlet 63 is blocked, that is, the side flushing port is blocked. At this time, the intelligent toilet 90 performs the bottom flushing function.

[0104] Third, push the pull rod 80 to make the handle 511 rotate in the opposite direction. At this time, the handle 511 drives the rotating part 512 to rotate in the opposite direction, so that the second baffle 532 on the second valve core 53 rotates in the opposite direction. The groove 515 on the connecting rod 514 can be clamped with the boss 522 on the second end cover 52 again and make a sound. At this time, the second baffle 532 on the second valve core 53 disengages from the second water outlet 63, the second water outlet 63 and the first water outlet 62 are opened, and the water flow in the water distribution valve 30 is discharged through the first water outlet 62 and the second water outlet 63.

[0105] In this embodiment, after the intelligent toilet 90 finishes flushing, the second water outlet 63 and the first water outlet 62 are opened, that is, the bottom flushing port and the side flushing port are opened, and the side flushing port can supply water to the ceramic cavity of the intelligent toilet 90.

[0106] Fourth, as Figure 23 shown in Figure 1 Continue to push the pull rod 80 to make the handle 511 continue to rotate in the opposite direction. The groove 515 on the connecting rod 514 disengages from the boss 522 on the second end cover 52, and the connecting rod 514 abuts against another third limiting part 521. At this time, the second valve core 53 returns to the initial position, the opening and closing assembly 20 blocks the pilot hole 14, thereby disconnecting the water inlet 61 of the pilot valve 10 and stopping supplying water to the water distribution valve 30.

[0107] Different from the prior art, the present application discloses a flushing device. By arranging an electric flushing component 40 and a manual flushing component 50 in a water distribution valve, when powered on, the flushing device can be controlled to work through the electric flushing component 40. When powered off, the flushing device can be controlled to work through the manual flushing component 50, that is, the flushing device can be controlled to work by mechanical operation, ensuring normal use in the case of power failure and eliminating the need for an external power source, effectively reducing the manufacturing cost of the flushing device.

[0108] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
