Description

Technical Field

[0001] This application relates to the field of smart home technology, and in particular to a flushing device and a smart toilet. Background Technology

[0002] With the improvement of living standards, smart toilets have become widely used. Current tankless smart toilets rely on an external battery box for flushing during power outages. Batteries power the solenoid valve and mainboard of the flushing valve, which in turn control the flushing function via a main control board. However, when a user needs to flush during a power outage, an external battery box is required. This not only eliminates the need for regular battery replacements, increasing the operating cost of the smart toilet, but also poses certain safety hazards. Utility Model Content

[0003] This application provides a flushing device to solve the problem that existing flushing devices require an external battery box when power is off.

[0004] To address the aforementioned technical problems, this application provides a flushing device, comprising: a pilot valve with an inlet; an opening / closing assembly disposed within the pilot valve, the inlet being controlled to open and close by the opening / closing assembly; and a water distribution valve having a accommodating space communicating with the pilot valve, wherein a manual flushing assembly and an electric flushing assembly are disposed within the accommodating space, the manual and electric flushing assemblies being connected to and controlling the state of the opening / closing assembly; and the water distribution valve having a first outlet and a second outlet communicating with the accommodating space; wherein the manual and electric flushing assemblies are movable within the accommodating space to drive the opening / closing assembly to open or close the inlet and control the opening / closing states of the first and second outlets.

[0005] The electric flushing assembly includes a drive unit, a first end cap, and a first valve core. The first end cap is located at one end of the water distribution valve to form a receiving space. The drive unit is located at the end of the first end cap away from the receiving space. The first valve core is located within the receiving space and is connected to the drive unit. The other end of the first valve core abuts against the opening and closing assembly. The first valve core rotates relative to the receiving space. The axial direction of the first valve core is perpendicular to the axial direction of the opening and closing assembly. When the first valve core rotates, it drives the opening and closing assembly to open or close the pilot valve.

[0006] The first valve core is provided with a first baffle plate, which is set to fit against the inner wall of the water distribution valve. A pressure relief hole is provided at the first outlet corresponding to the first baffle plate. The pressure relief hole is used to relieve pressure on the water distribution valve when the first baffle plate is aligned with the first outlet.

[0007] The first valve core includes a first rotating shaft and a first rotating disk. One end of the first rotating shaft is connected to a driving component, and the other end is connected to the first rotating disk. A first baffle is disposed on the side wall of the first rotating shaft, and the edge of the first rotating disk is connected to the opening and closing component. The first rotating disk is an irregular semi-circular arc shape, and the opening and closing component is inserted into the first rotating disk.

[0008] The manual flushing assembly includes an operating lever, a second end cap, and a second valve core. The second end cap is located at the end of the water distribution valve furthest from the first end cap. The operating lever is inserted into the second end cap and is at least partially exposed. The second valve core is located within the accommodating space and is connected to the operating lever. The other end of the second valve core abuts against the opening and closing assembly. The second valve core is coaxially arranged with the first valve core. When the second valve core rotates, it drives the opening and closing assembly to open or close the pilot valve.

[0009] The second valve core has a second baffle and a second turntable at its edge. The second baffle is fitted to the inner wall of the water distribution valve. The second turntable is an irregular semi-circular arc shape, and the opening and closing components are inserted into the inner side of the second turntable.

[0010] The operating lever includes a handle and a rotating component. The handle and the rotating component are connected and exposed to the second end cover. The rotating component has an annular protrusion, which is disposed between the second end cover and the second valve core to clamp and fix the operating lever.

[0011] The manual flushing assembly also includes a torsion spring. The end of the rotating part away from the handle is provided with a slot. One end of the torsion spring is engaged with the second valve core, and the other end is engaged with the slot.

[0012] The control lever also includes a connecting rod, one end of which is connected to the handle and the other end of which is connected to the rotating component. A groove is provided at the end of the connecting rod near the second end cover, and a boss that mates with the groove is provided on the second end cover.

[0013] To address the aforementioned issues, this application also provides a smart toilet, comprising: a flushing device, wherein the flushing device is any of the above-mentioned flushing devices.

[0014] The beneficial effects of this application are as follows: Unlike the prior art, this application sets up an opening and closing component to control the opening and closing of the pilot valve inlet, connects the water distribution valve and the pilot valve, and sets up a manual flushing component and an electric flushing component in the water distribution valve. When the power is on, the electric flushing component can control the flushing device to drain water. When the power is off, the manual flushing component can be controlled to move in the water distribution valve through mechanical operation to control the flushing device to drain water. This can ensure the normal use of the flushing device when the power is off, and no external power supply is required, which can effectively reduce costs. Attached Figure Description

[0041] Please see Figure 1 , Figure 1 This is a structural schematic diagram of the cross-sectional view of the flushing device provided in this application.

[0042] This application provides a flushing device. For example... Figure 1 and Figure 2 As shown, the flushing device of this embodiment includes: a pilot valve 10, an opening and closing assembly 20, and a water distribution valve 30. The pilot valve 10 has a water inlet 61. The opening and closing assembly 20 is disposed within the pilot valve 10, and the water inlet 61 is controlled to open and close by the opening and closing assembly 20. The water distribution valve 30 has a receiving space 31 communicating with the pilot valve 10. A manual flushing assembly 50 and an electric flushing assembly 40 are disposed within 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 has a first water outlet 62 and a second water outlet 63 communicating with the receiving space 31. The manual flushing assembly 50 and the electric flushing assembly 40 can move within the receiving space 31 to drive the opening and closing assembly 20 to open or close the water 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, a control assembly 20 is provided inside the pilot valve 10. The pilot valve 10 has an inlet 61, and an inlet pipe is connected to the inlet 61 for supplying water to the pilot valve 10. Specifically, the control assembly 20 is used to control the opening and closing of the inlet 61, thereby controlling the flow of water into the pilot valve 10.

[0044] The water distribution valve 30 has a accommodating space 31, which is connected to the pilot valve 10. After the opening and closing component 20 opens the water 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 component 20 controls the water 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 provided within the accommodating 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 within the pilot valve 10. That is, the operating state of the opening and closing assembly 20 can be controlled by the manual flushing assembly 50 and the electric flushing assembly 40. The water distribution valve 30 is provided with a first outlet 62 and a second outlet 63 that communicate with the accommodating space 31. After the pilot valve 10 pumps water into the water distribution valve 30, the first outlet 62 and the second outlet 63 can be used to divide the flow, and the liquid can be discharged through the first outlet 62 and the second outlet 63.

[0046] In some embodiments, the liquid in the accommodating space 31 can be discharged through the first outlet 62 and the second outlet 63 respectively, or it can be discharged through the first outlet 62 and the second outlet 63 alone. 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, thereby controlling the opening and closing of the first outlet 62 and the second outlet 63. The movement of the manual flushing assembly 50 and the electric flushing assembly 40 within the accommodating space 31 can drive the state of the opening and closing assembly 20 within the pilot valve 10, and control the opening and closing of the inlet 61 of the pilot valve 10 through the opening and closing assembly 20.

[0047] The diverter valve 30 can be cylindrical, meaning the inner wall of its accommodating space 31 is arc-shaped. 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, thereby controlling the opening and closing state of the inlet 61 of the pilot valve 10. Furthermore, when the manual flushing assembly 50 and the electric flushing assembly 40 rotate within the accommodating space 31, they can block either the first outlet 62 or the second outlet 63, thus diverting the liquid flow. The manual flushing assembly 50 and the electric flushing assembly 40 can rotate independently within the accommodating space 31, meaning they can each control the opening and closing assembly 20 to open or close the inlet 61, and can also control the opening and closing states of the first outlet 62 and the second outlet 63.

[0048] In some embodiments, the water distribution valve 30 and the pilot valve 10 can be integrated, that is, the pilot valve 10 and the water distribution valve 30 can share a single housing. By integrating the water distribution valve 30 and the pilot valve 10, the overall size of the flushing device can be effectively reduced, which facilitates the installation of the flushing device within the entire machine and effectively improves the layout of the flushing device within the entire machine.

[0049] In one application scenario, the flushing device can be installed in a smart toilet, meaning the electric flushing component 40 in the flushing device can be connected to household electricity. When the smart toilet is in use, the electric flushing component 40 can be driven to rotate within the receiving space 31 of the water distribution valve 30. When the electric flushing component 40 rotates, it drives the opening and closing component 20 to move, thereby opening the inlet 61 of the pilot valve 10, allowing water to flow through the pilot valve 10 into the water distribution valve 30. Furthermore, when the electric flushing component 40 rotates within the receiving space 31, it can block the first inlet 62 or the second inlet 63, allowing water to be discharged through the first outlet 62 and / or the second outlet 63.

[0050] Furthermore, during the use of this smart toilet, power outages are inevitable, at which point the electric flushing assembly 40 will not function properly. In such cases, the user can manually control the manual flushing assembly 50 to rotate within the receiving space 31 of the water distribution valve 30. When the manual flushing assembly 50 rotates within the receiving space 31, it drives the opening and closing assembly 20 to open, thereby opening the inlet 61 of the pilot valve 10. This allows water to flow through the pilot valve 10 into the water distribution valve 30. Furthermore, when the manual flushing assembly 50 rotates within the receiving space 31, it can block either the first or second inlet 61, allowing water to drain through the first outlet 62 and / or the second outlet 63. When the flushing device is powered off, the water distribution valve 30 can be controlled by the manual flushing component 50 to drain water. It does not require the electric flushing component 40 to drive the water distribution valve 30 to drain water. In other words, the flushing device does not require an external power source. In the event of a power outage, the flushing device can be controlled by mechanical operation, meaning that the flushing device can be used normally when the power is off.

[0051] In the above embodiment, by setting the opening and closing component 20 to control the opening and closing of the inlet 61 of the pilot valve 10, the water distribution valve 30 is connected to the pilot valve 10, and a manual flushing component 50 and an electric flushing component 40 are set in the water distribution valve 30. When the power is on, the electric flushing component 40 can control the flushing device to drain water. When the power is off, the manual flushing component 50 can be controlled to move in the water distribution valve 30 by mechanical operation to control the flushing device to drain water. This can ensure the normal use of the flushing device when the power is off, and no other external power source is required, which can effectively reduce costs.

[0052] In an optional embodiment, such as Figure 2 As shown, the pilot valve 10 includes a cover 11, a pilot support 12, and a pilot diaphragm 13. The cover 11 is located at the end of the pilot valve 10 away from the diverter valve 30. The pilot support 12 is located inside the cover 11, and the pilot diaphragm 13 is clamped and fixed by the cover 11 and the pilot support 12. A pilot hole 14 is provided on the end face of the cover 11 near the diverter valve 30. The axis of the pilot hole 14 is parallel to the axis of the cover 11, and the pilot hole 14 is located at the edge of one end of the cover 11. The opening and closing assembly 20 abuts against the pilot hole 14.

[0053] When the flushing device is not in use, i.e., when the pilot valve 10 and the water distribution valve 30 are not required to pump water, the opening and closing component 20 can abut against the pilot hole 14, i.e., the pilot hole 14 is blocked by the opening and closing component 20, thereby closing the water inlet 61 of the pilot valve 10. When the flushing device is required, i.e., the pilot valve 10 needs to be opened, the opening and closing component can be controlled to move away from the pilot hole 14, the pilot hole 14 opens, thereby opening the water inlet 61 of the pilot valve 10, thereby transmitting water flow through the pilot valve 10 to the water distribution valve 30.

[0054] In this embodiment, as Figure 3 As shown, the opening and closing assembly 20 includes a piston rod 21, a rubber component 23, and a reset component 22. The reset component 22 is sleeved on the piston rod 21. One end of the reset component 22 is connected to the inner wall of the pilot valve 10 away from the water distribution valve 30, and the other end is connected to the end of the piston rod 21 near the pilot valve 10. The rubber component 23 is disposed at the end of the piston rod 21 near the pilot valve. 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, such as Figure 4 As shown, a slide rail 211 is provided on the piston rod 21 along the axis of the piston rod 21, and a first column 212 and a second column 213 are provided on the opposite side of the piston rod 21 near the end of the water distribution valve 30. 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 within the accommodating space 31 of the water distribution valve 30, it can drive the piston rod 21 to slide along the axis of the pilot hole 14, thereby controlling the opening and closing of the inlet 61 of the pilot valve 10 by blocking or disengaging from the pilot hole 14. Furthermore, the slide rail 211 can cooperate with the inner wall of the water distribution valve 30, thereby preventing the piston rod 21 from rotating while sliding along the axis of the pilot hole 14, which would cause the cooperation with the electric flushing assembly 40 and the manual flushing assembly 50 to fail.

[0056] When using the flushing device, the manual flushing assembly 50 or the electric flushing assembly 40 can be controlled to rotate within the water distribution valve 30, thereby driving the piston rod 21 away from the pilot hole 14. The pilot hole 14 opens, thus opening the water inlet 61 of the pilot valve 10, allowing the pilot valve 10 to supply water to the water distribution valve 30, which is then discharged through the first outlet 62 and / or the second outlet 63. When the flushing device is no longer in use, 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, thereby closing the water inlet 61 of the pilot valve 10.

[0057] In some embodiments, such as Figure 3As shown, a rubber component 23 is provided at the end of the piston rod 21 near the pilot hole 14. Under the action of the reset component 22, the rubber component 23 can seal the pilot hole 14. The diameter of the pilot hole 14 is 0.8mm-1.2mm. According to the pressure formula F=P*S, where F is the force, S is the area of ​​force application, and P is the pressure. That is, the smaller the area of ​​force application of the pilot hole 14, the smaller the pressure of the water flow on the rubber component 23, and correspondingly, the smaller the elastic force required by the reset component 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 pilot valve 10 inlet 61 through the opening and closing assembly 20 is effectively guaranteed.

[0058] In some embodiments, such as Figure 2 As shown, the electric flushing assembly 40 includes a drive unit 41, a first end cap 42, and a first valve core 43. The first end cap 42 is disposed at one end of the water distribution valve 30 to form a receiving space 31. The drive unit is disposed at the end of the first end cap 42 away from the receiving space 31. The first valve core 43 is disposed within the receiving space 31 and connected to the drive unit 41. The other end of the first valve core 43 abuts against the opening and closing assembly 20. The first valve core 43 rotates relative to the receiving space 31. 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] The drive element 41 is used to connect to a power source, such as a household power supply. The drive element 41 can be a motor, which can drive the first valve core 43 to rotate within the receiving space 31 of the water distribution valve 30. In other embodiments, the drive element 41 can also be other power-providing devices, such as a cylinder, as long as the first valve core 43 can be driven to rotate within the receiving space 31 through other linkage components. Specifically, this application does not make specific limitations here.

[0060] In some embodiments, a first end cap 42 is provided at one end of the water distribution valve 30. The first end cap 42 is detachably connected to the water distribution valve 30, thereby forming an accommodating space 31. A first valve core 43 passes through the first end cap 42 and is connected to the drive member 41, wherein the rotation axis of the drive member 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 drive member 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 drive component 41 drives the first valve core 43 to rotate within the accommodating space 31. When the first valve core 43 rotates, it can drive the opening and closing component 20 away from the pilot hole 14 along the axis of the pilot hole 14, thereby opening the pilot hole 14. After the pilot hole 14 is opened, the inlet 61 of the pilot valve 10 can be opened. After the inlet 61 is opened, the water flow can enter the water distribution valve 30 through the pilot valve 10. After entering the accommodating space 31 of the water distribution valve 30, it can be discharged through the first outlet 62 and / or the second outlet 63.

[0062] In an optional embodiment, combined with Figure 5 As shown, a first limiting member (not shown) is provided on the end face of the first end cap 42 near the first valve core 43, and a second limiting member 438 is provided on the end of the first valve core 43 near the first end cap 42. The first limiting member and the second limiting member 438 can cooperate with each other, so that 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 by the cooperation of the first limiting member and the second limiting member 438, so as to avoid the occurrence of excessive rotation angle. The first limiting member and the second limiting member 438 can be protruding structures or other structures, which are not specifically limited in this application.

[0063] In some embodiments, combined with Figure 6 As shown, a first baffle 44 is provided on the first valve core 43. The first baffle 44 is fitted against the inner wall of the water distribution valve 30. A pressure relief hole 442 is provided on the first baffle 44 at the first outlet 62. The pressure relief hole 442 is used to relieve pressure on the water distribution valve 30 when the first baffle 44 is aligned with the first outlet 62. The first baffle 44 is arc-shaped, meaning that it can be completely fitted against the inner wall of the water distribution valve 30. When the driving member 41 drives the first valve core 43 to rotate, the first baffle 44 can rotate within the accommodating space 31, thereby blocking the first outlet 62 and the second outlet 63 respectively, thus diverting the water flow entering the water distribution valve 30 through the first baffle 44.

[0064] When the first valve core 43 rotates within the accommodating space 31, it drives the opening and closing assembly 20 away from the pilot hole 14, thereby opening the inlet 61 of the pilot valve 10 and supplying water to the water distribution valve 30. As the first valve core 43 rotates, the first baffle 44 rotates accordingly, blocking the first outlet 62 and allowing water to flow through the second outlet 63. Driven by the driving component 41, the first valve core 43 continues to rotate, and the first baffle 44 moves away from the first outlet 62. At this point, the first baffle 44 partially blocks both the first and second outlets 62, allowing water to flow through both outlets. As the first baffle 44 continues to rotate, it completely disengages from the first outlet 62 and completely blocks the second outlet 63, allowing water to flow through the first outlet 62.

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

[0066] In some embodiments, when the first valve core 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 outlet 62. Specifically, this application does not make specific limitations here.

[0067] The first baffle 44 is equipped with a pressure relief hole 442 at the position 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 accommodating space 31 can be discharged through the pressure relief hole 442 and the corresponding first water outlet 62, to prevent excessive water pressure in the accommodating space 31 of the water distribution valve 30 from damaging the flushing device. For example, when the flushing device is installed in a smart toilet, i.e., when the first water outlet 62 corresponds to the bottom flush of the smart toilet, i.e., when the pressure relief hole 442 corresponds to the bottom flush, the pressure of the flushing device is relieved through the pressure relief hole 442 and the bottom flush.

[0068] In a specific application scenario, when the flushing device is used in a smart toilet, the first water outlet 62 is the bottom flush port of the smart toilet, and the second water outlet 63 is the side flush port. The first valve core 43 can be rotated by the drive component 41, thereby controlling the closing of the bottom flush port and the side flush port respectively, for flushing the smart toilet. When the first baffle 44 completely blocks the second water outlet 63, i.e., the side flush port, the smart toilet has completed both the bottom and side flushes. The drive component 41 can drive the first baffle 44 to rotate in the opposite direction and open the second water outlet 63 to replenish water to the ceramic base inside the smart toilet.

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

[0070] Specifically, a first arcuate protrusion 433 and a second arcuate protrusion 435 are provided at the edge of the first turntable 432 away from the second end cover 52. The first arcuate protrusion 433 and the second arcuate protrusion 435 are concentrically arranged, and the diameter of the first arcuate protrusion 433 is larger than the diameter of the second arcuate protrusion 435. The first arcuate protrusion 433 and the second arcuate protrusion 435 are connected by a first straight 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 sidewalls of the first arcuate protrusion 433, the second arcuate protrusion 435, and the first straight protrusion 434. When the first column 212 abuts against the inner sidewall of the first arcuate protrusion 433, 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. When the first column 212 of the piston rod 21 is on the inner wall of the first arc protrusion 433, the inlet 61 of the pilot valve 10 is closed; when the first column 212 of the piston rod 21 is on the inner wall of the second arc protrusion 435, the inlet 61 of the pilot valve 10 is opened.

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

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

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

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

[0075] Fourth, after pumping water, the drive unit 41 drives the first turntable 432 to rotate in the opposite direction. Under the action of the reset unit 22, the first column 212 of the piston rod 21 slides from the inner wall of the second arc protrusion 435 and the inner wall of the first straight section to the inner wall of the first arc section. At this time, the reset unit 22 gradually resets, driving the piston rod 21 to gradually move towards the pilot hole 14 until the rubber part 23 on the piston rod 21 completely abuts against the pilot hole 14. At this time, the inlet 61 of the pilot valve 10 closes and stops supplying water to the water distribution valve 30.

[0076] In some embodiments, a latching member 436 is provided on the side wall of the first rotating shaft 431, and a latching groove 437 is formed on the latching member 436. A latching member 441 is provided on the first baffle 44, and the latching member 441 is latched into the latching groove 437. That is, the first baffle 44 is detachably mounted on the first rotating shaft 431. In other embodiments, the first baffle 44 may be integrally mounted with the first rotating shaft 431, and this application does not make specific limitations here.

[0077] In an optional 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 the 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 is at least partially exposed to 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] In the event of a power outage, meaning the electric flushing assembly 40 cannot function properly, flushing can be completed using the manual flushing assembly 50 when the user needs to flush. The operating lever 51 of the manual flushing assembly 50 passes through the second end cover 52 and is connected to the second valve core 53. During flushing, the operating lever 51 can be mechanically moved, causing the second valve core 53 to rotate within the accommodating space 31 of the water distribution valve 30. This, in turn, causes the opening and closing assembly 20 to move along the axis of the pilot hole 14, thereby opening the inlet 61 of the pilot valve 10. This allows the pilot valve 10 to supply water to the water distribution valve 30, which is then discharged through the first outlet 62 and / or the second outlet 63.

[0079] In some embodiments, combined 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 the side of the second rotating shaft 531 closest to the first valve core 43. The first hole 537 engages with the first rotating shaft 431 of the first valve core 43, allowing the first rotating shaft 431 of the first valve core 43 to be movably connected within the first hole 537, meaning the first valve core 43 and the second valve core 53 are coaxially arranged. A second hole 538 is provided at the end of the second rotating shaft 531 furthest from the first valve core 43. The second hole 538 is used to connect with an operating lever 51, thereby facilitating control of the rotation of the second valve core 53 via the operating lever 51.

[0080] In some embodiments, a second baffle 532 and a second rotary disc 533 are provided at the edge of the second valve core 53. The second baffle 532 is disposed against the inner wall of the water distribution valve 30, and the second rotary disc 533 is an irregular semi-circular arc shape. The opening and closing assembly 20 is inserted into the inner side of the second rotary disc 533. The second valve core 53 is disposed in the receiving space 31 of the water distribution valve 30. The second rotary disc 533 is provided at the edge of the second valve core 53, and the second baffle 532 is provided at the edge of the second rotary disc 533 at a position opposite to it, that is, the second baffle 532 is disposed close to the first valve core 43. When flushing is required, the movable operating lever 51 can rotate around the axis of the second rotating shaft 531, thereby driving the second valve core 53 to rotate within the accommodating space 31. The opening and closing component 20 is inserted inside the edge of the second rotating disk 533. When the second rotating disk 533 rotates, the second rotating disk 533 drives the opening and closing component 20 to move, thereby controlling the opening and closing of the pilot valve 10 inlet 61, as well as the opening and closing status of the first outlet 62 and the second outlet 63.

[0081] The first valve core 43 and the second valve core 53 are disposed within the accommodating space 31 of the water distribution valve 30. 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 movably disposed, meaning that the first valve core 43 and the second valve core 53 can rotate independently within the accommodating space 31 of the water distribution valve 30. The first rotating plate 432 of the first valve core 43 and the second rotating plate 533 of the second valve core 53 are disposed opposite to each other on opposite sides of the opening and closing assembly 20. Specifically, the first column 212 on the piston rod 21 is inserted into the inner wall of the first rotating plate 432, and the second column 213 is inserted into the inner wall of the second rotating plate 533. That is, when the first rotating plate 432 and the second rotating plate 533 rotate independently, they can drive the piston rod 21 to move independently. Furthermore, the first turntable 432 and the second turntable 533 are arranged opposite to each other and their shapes are compatible, which can effectively prevent the first turntable 432 or the second turntable 533 from interfering with the opening and closing component 20 when the first turntable 432 or the second turntable 533 rotates independently.

[0082] Specifically, the second turntable 533 has a third arcuate protrusion 534 and a fourth arcuate protrusion 536 near the edge of the first valve core 43. The third arcuate protrusion 534 and the fourth arcuate protrusion 536 are concentrically arranged, and the diameter of the third arcuate protrusion 534 is larger than the diameter of the fourth arcuate protrusion 536. The third arcuate protrusion 534 and the fourth arcuate 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 walls of the third arcuate protrusion 534, the fourth arcuate protrusion 536, and the second straight protrusion 535. When the second column 213 abuts against the inner wall of the third arcuate protrusion 534, the rubber part 23 on the piston rod 21 abuts against the pilot hole 14, thereby sealing the pilot hole 14. When the second column 213 abuts against the inner wall of the fourth arc protrusion 536, the piston rod 21 disengages from the pilot hole 14, causing the pilot valve 10 to open and supply water to the water distribution valve 30.

[0083] When the operating lever 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 similar to the working states of the first turntable 432 mentioned above, and will not be described in detail here.

[0084] In some embodiments, combined with Figure 12 and 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 installed inside the water distribution valve 30, the first valve core 43 and the second valve core 53 can be coaxially arranged.

[0085] In some embodiments, such as Figure 9 As shown, the operating lever 51 includes a handle 511 and a rotating member 512. The handle 511 and the rotating member 512 are connected and exposed on the second end cover 52. The rotating member 512 has an annular protrusion 513, which is disposed between the second end cover 52 and the second valve core 53 to clamp and fix the operating lever 51. When the second end cover 52 is placed on the water distribution valve 30, the operating lever 51 can pass through the second end cover 52 and connect to the second valve core 53, and the annular protrusion 513 on the rotating member 512 is clamped and fixed between the second end cover 52 and the second valve core 53.

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

[0087] In some embodiments, such as Figure 15 As shown, the manual flushing assembly 50 also includes a torsion spring 54, and the end of the rotating member 512 away from the handle 511 is provided with a slot 516, which is combined with... Figure 16 As shown, one end of the torsion spring 54 is snapped onto the second valve core 53, in conjunction with... Figure 10 The other end is engaged in the slot 516. Specifically, when the operating rod 51 is mounted on the water distribution valve 30, one end of the torsion spring 54 can be fixed in the slot 516 on the rotating member 512, and the other end can be fixed on the water distribution valve 30. Furthermore, a connector 539 is provided in the second hole 538 on the second rotating shaft 531, which can be engaged in the slot 516. Thus, by rotating the operating rod 51, the second valve core 53 can be rotated within the receiving space 31 of the water distribution valve 30.

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

[0089] In some embodiments, the operating lever 51 further includes a connecting rod 514, one end of which is connected to the handle 511 and the other end to the rotating member 512. A groove 515 is provided at the end of the connecting rod 514 near the second end cap 52, and a boss 522 that mates with the groove 515 is provided on the second end cap 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 cap 52 away from the second valve core 53. When the handle 511 is turned, the handle 511 drives the connecting rod 514 to rotate. When the groove 515 on the connecting rod 514 rotates to the corresponding boss 522 on the second end cap 52, a sound is generated, indicating the angle of rotation. For example, when the groove 515 engages with the boss 522 and a sound is generated, it indicates that drainage is occurring at the first outlet 62 or the second outlet 63 of the water distribution valve 30. The boss 522 can be set as a semi-circular arc to reduce the friction when the groove 515 and the boss 522 are engaged. The specific structure can be set as needed, and this application does not make specific limitations here.

[0090] In some embodiments, such as Figure 11As shown, two third limiting members 521 are provided on the end face of the second end cap 52 away from the second valve core 53, in conjunction with... Figure 14 As shown, the third limiting member 521 can cooperate with the connecting rod 514 of the operating rod 51, thereby limiting 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 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 outlet 62 and the second outlet 63, that is, the second baffle 532 does not block the first outlet 62 and the second outlet 63.

[0092] In a specific application scenario, when powered on, the first valve core 43 can be rotated within the water distribution valve 30 by the drive component 41, thereby enabling the flushing device to perform the corresponding pumping operation. When powered off, the second valve core 53 can be rotated within the water distribution valve 30 by moving the operating lever 51, thereby enabling the flushing device to perform the corresponding pumping operation. Furthermore, since the first disc 432 of the first valve core 43 and the second disc 533 of the second valve core 53 are positioned opposite each other on both sides of the opening and closing assembly 20, there will be no interference with the second valve core 53 when the electric flushing assembly 40 performs the pumping operation. Similarly, the manual flushing assembly 50 will not interfere with the first valve core 43 when performing the pumping operation.

[0093] In some embodiments, such as Figure 2 As shown, the pilot valve 10 is equipped with an air isolation valve 70, the opening and closing states of which are opposite to those of the pilot valve 10. That is, when the pilot valve 10 is open, the water flow inside the pilot valve 10 can rise and press against the isolation valve core 71 inside the air valve, thus achieving a sealing effect. When the pilot valve 10 is closed, the isolation valve core 71 of the air isolation valve 70 falls due to the lack of water flow, allowing the pilot valve 10 and the water distribution valve 30 to communicate with the atmosphere, effectively preventing backflow.

[0094] This application also provides a smart toilet, such as Figure 18 As shown, the smart toilet 90 includes a flushing device, which is any of the flushing devices described in the above embodiments.

[0095] In some embodiments, combined with Figure 19 and Figure 20As shown, the smart toilet 90 includes a housing 91, on which a support member 911 is provided. The support member 911 has a support hole 912, and a pull rod 80 is movably connected within the support hole 912. One end of the pull rod 80 is movably connected to a handle 511 on an operating lever 51, and the other end has a pull ring 81, which is at least partially exposed outside the housing 91. Specifically, one end of the pull rod 80 has a slider 82, and a groove (not shown) is provided inside the handle 511. The slider 82 of the pull rod 80 slides within the groove of the handle 511. That is, when the pull rod 80 is pulled, the slider 82 on the pull rod 80 can slide relative to it within the groove of the handle 511, thereby avoiding interference or jamming when the pull rod 80 is pulled.

[0096] In some embodiments, the housing 91 is provided with a receiving cavity 93 for accommodating the pull ring 81, and a decorative cover 92 is provided on the outside of 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 aesthetics of the smart toilet 90.

[0097] In this embodiment, a through hole (not shown) with a diameter smaller than that of the pull ring 81 is provided on the inner wall of the cavity 93 of the housing 91. The pull rod 80 can be limited through the through hole to prevent the movement beyond the limit.

[0098] In a specific application scenario, when the smart toilet 90 needs to be used in the event of a power outage, the pull ring 81 on the pull rod 80 can be pulled, causing the pull rod 80 to rotate the operating lever 51. This activates the flushing device, enabling the smart toilet 90 to perform the corresponding bottom flush and side flush. After completing the bottom flush and side flush, the pull rod 80 can be pushed further into the smart toilet 90, causing the operating lever 51 to move in the opposite direction, thus returning the second valve core 53 to its initial position.

[0099] In this embodiment, when using the manual flushing assembly 50 to flush, there are four states:

[0100] First, such as Figure 21 As shown, by pulling the lever 80 and rotating the handle 511 on the operating lever 51, the rotating component 512 rotates, causing the second valve core 53 to rotate within the accommodating space 31 of the water distribution valve 30. The rotation of the second valve core 53 causes the opening / closing assembly 20 to move away from the pilot hole 14 along its axial direction, opening the inlet 61 of the pilot valve 10 and supplying water to the water distribution valve 30. At this time, the groove 515 on the connecting rod 514 engages with the protrusion 522 on the second end cover 52, producing a "click" sound. The second baffle 532 of the second valve core 53 does not block the first outlet 62 and the second outlet 63, allowing water to flow out of the water distribution valve 30 through the first outlet 62 and the second outlet 63.

[0101] In this embodiment, when the flushing device is installed inside the smart toilet 90, the first water outlet 62 is a bottom flush outlet and the second water outlet 63 is a side flush outlet. That is, when the groove 515 on the connecting rod 514 is engaged with the protrusion 522 on the second end cover 52, the smart toilet 90 performs the function of separating bottom flush and side flush.

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

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

[0104] Third, pushing the lever 80 causes the handle 511 to rotate in the opposite direction. At this time, the handle 511 drives the rotating part 512 to rotate in the opposite direction, causing the second baffle 532 on the second valve core 53 to rotate in the opposite direction. The groove 515 on the connecting rod 514 can then engage with the boss 522 on the second end cover 52 again, producing a sound. At this time, the second baffle 532 on the second valve core 53 disengages from the second outlet 63, and the second outlet 63 and the first outlet 62 open. The water in the water distribution valve 30 is discharged through the first outlet 62 and the second outlet 63.

[0105] In this embodiment, after the smart toilet 90 completes flushing, the second water outlet 63 and the first water outlet 62 open, that is, the bottom flush and the side flush open. The side flush can replenish water into the ceramic cavity of the smart toilet 90.

[0106] Fourth, such as Figure 23 and Figure 1 As shown, by continuing to push the lever 80, the handle 511 continues 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 member 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 the water supply to the water distribution valve 30.

[0107] Unlike existing technologies, this application discloses a flushing device that incorporates an electric flushing component 40 and a manual flushing component 50 within a water distribution valve. When powered on, the electric flushing component 40 controls the flushing device's operation. When the power is off, the manual flushing component 50 controls the flushing device, allowing for mechanical operation and ensuring normal use even in power outages. Furthermore, it eliminates the need for an external power source, effectively reducing the manufacturing cost of the flushing device.

[0108] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
