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 been widely used. Currently, for toilets with water tanks, the integration of the flushing device and the water tank is low, resulting in the flushing device and water tank occupying a large space in the toilet, affecting the size of the toilet. In addition, the toilet's water replenishment delay effect is poor, and the toilet's water supply pipeline is relatively simple. Utility Model Content

[0003] This application provides a flushing device to solve the problem that flushing devices in the prior art occupy a large volume.

[0004] To address the aforementioned technical problems, this application provides a flushing device, comprising: a water tank; an inlet pipe for supplying water to the water tank; a water valve assembly disposed within the water tank, the water valve assembly including a first inlet valve, a second inlet valve, and a diverter valve, the inlet of the first inlet valve being connected to the inlet pipe, and the outlet being connected to the inlet of the diverter valve; the inlet of the second inlet valve being connected to the inlet pipe, and the outlet being connected to the water tank; a water pump disposed within the water tank, the outlet of the water pump being connected to the diverter valve; the diverter valve having a first outlet and a second outlet, for selectively guiding the water flow from its inlet to the first outlet and / or the second outlet; a floating assembly sleeved on the outside of the inlet pipe; a linkage mechanism connected between the floating assembly and the second inlet valve; and a control mechanism disposed on the diverter valve, the control mechanism being configured to: drive the linkage mechanism to operate according to the working state of the diverter valve, thereby controlling the opening or closing of the second inlet valve.

[0005] The first and second inlet valves are each equipped with an isolation component, which is used to determine whether the inlet valve where the controller is located is connected to or not connected to the outside world.

[0006] The water distribution valve includes a valve body, a drive component, and a water distribution valve core. The drive component is located at one end of the valve body, and its output end is connected to the water distribution valve core and the control mechanism. The water distribution valve core is provided with a baffle plate, which is fitted against the inner wall of the water distribution valve and is used to selectively block the first outlet or the second outlet.

[0007] The first inlet valve is a pilot valve with a first pilot hole on its valve body. The flushing device also includes a pilot control valve, which is driven by the control mechanism of the water distribution valve and is used to control the opening and closing of the first pilot hole to control the opening and closing state of the first inlet valve.

[0008] The second inlet valve is a pilot valve with a second pilot hole. The linkage mechanism includes a connector and a sealing gasket. One end of the connector is movably connected to the floating component, and the other end is provided with a sealing gasket. The control mechanism includes a driveable locking component. The locking component is configured such that when it engages with the floating component, it forces the floating component to block the second pilot hole through the connector, thereby closing the second inlet valve. When it disengages from the floating component, the floating component can float freely, allowing the sealing gasket to disengage from the second pilot hole, thereby opening the second inlet valve.

[0009] The floating assembly includes a buoy and a floating seat. The floating seat is fitted on the outside of the buoy and has a floating component at the end away from the buoy. One end of the floating component has a boss and the other end has a frustum. The floating seat has a slot and a drain hole communicating with the slot. The boss is movably disposed in the slot and is limited by the boss. The connection state between the floating component and the slot can control the opening and closing state of the drain hole.

[0010] The flushing device also includes a water supply pipe, one end of which is connected to the second inlet valve and the other end of which is connected to the water tank; the water distribution valve is equipped with a first outlet pipe and a second outlet pipe that are respectively connected to the first outlet and the second outlet; a one-way valve is provided at the connection between the water pump and the water distribution valve.

[0011] The flushing device also includes a hydraulic sensor, which is installed in the water inlet pipe to detect water pressure; and a control component, which is electrically connected to the hydraulic sensor, the drive of the water distribution valve, and the water pump, and is used to control the working status of the drive and the water pump according to the signal from the hydraulic sensor.

[0012] To address the aforementioned issues, a second aspect of this application also provides a smart toilet, including the flushing device of any of the above-mentioned components.

[0013] The smart toilet includes an outer shell; a fixing component is provided on the outer shell, and a slot is provided on the outer side wall of the water tank. The slot is inserted and fixed to the fixing component. An inner wall is formed inside the outer shell to form a first accommodating space and a second accommodating space. A flushing device is set in the first accommodating space. A first nozzle and a second nozzle are provided on the inner wall. The first nozzle is set on the side wall of the inner wall and is connected to the water outlet pipe. The second nozzle is set at the bottom of the inner wall and is connected to the second water outlet pipe.

[0014] The beneficial effects of this application are as follows: Unlike the prior art, this application sets a floating component in the water tank and connects the floating component and the second inlet valve with a linkage mechanism. The control mechanism can drive the linkage mechanism to operate according to the working state of the water valve to control the opening and closing state of the second inlet valve. This allows selective conduction of the first and second inlet valves, avoiding the diversion of water flow by multiple water channels when the flushing device is working. This effectively improves the applicability of the flushing device. Furthermore, the second inlet valve can be used to replenish water to the water tank, and water can be drained through the first outlet and / or the second outlet, effectively improving the multifunctionality of the flushing device. The integrated flushing device also effectively reduces the volume occupied by the flushing device. Attached Figure Description

[0045] Please see Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the flushing device provided in this application.

[0046] This application provides a flushing device. For example... Figure 1 and Figure 17 As shown, the flushing device of this embodiment includes: a water tank 10, a water valve assembly 30, a water pump 50, a floating assembly 20, a water inlet pipe 40, and a linkage mechanism 60. The water inlet pipe 40 is used to supply water to the water tank 10. The water valve assembly 30 is disposed inside the water tank 10 and includes a first water inlet valve 31, a second water inlet valve 32, and a water distribution valve 33. The inlet of the first water inlet valve 31 is connected to the water inlet pipe 40, and the outlet is connected to the inlet of the water distribution valve 33. The inlet of the second water inlet valve 32 is connected to the water inlet pipe 40, and the outlet is connected to the water tank 10. The water pump 50 is disposed inside the water tank 10, and the outlet of the water pump 50 is connected to the water distribution valve 33. Figure 2 As shown, the water distribution valve 33 has a first outlet 331 and a second outlet 332, used to selectively guide the inlet water flow to the first outlet 331 and / or the second outlet 332. The floating component 20 is sleeved on the outside of the inlet pipe 40, and the linkage mechanism 60 is connected between the floating component 20 and the second inlet valve 32. Figure 2 As shown, the flushing device also includes a control mechanism 73, which is mounted on the water distribution valve 33. The control mechanism 73 is configured to drive the linkage mechanism 60 to operate according to the working state of the water distribution valve 33, thereby controlling the opening or closing of the second water inlet valve 32. That is, the water valve assembly 30, the water pump 50, and the floating assembly 20 are all integrated within the water tank 10, effectively reducing the volume occupied by the flushing device. The water distribution valve 33, the first water inlet valve 31, and the second water inlet valve 32 can share a single housing; that is, the housings of the water distribution valve 33, the first water inlet valve 31, and the second water inlet valve 32 can be designed as a single piece. This application does not impose specific limitations on this design.

[0047] In some embodiments, the floating component 20 is disposed within the water tank 10, meaning the floating component 20 can rise and fall based on the water level within the water tank 10, and the water level within the water tank 10 can control the raising and lowering of the floating component 20. A water valve assembly 30 is disposed within the water tank 10. Specifically, the water valve assembly 30 includes a first inlet valve 31, a second inlet valve 32, and a diverter valve 33. The first inlet valve 31 is connected to the inlet pipe 40 and the diverter valve 33. Specifically, the inlet of the first inlet valve 31 is connected to the inlet pipe 40, and the outlet of the first inlet valve 31 is connected to the diverter valve 33. The inlet and outlet of the first inlet valve 31 are respectively connected to the inlet pipe 40 and the diverter valve 33. One end of the second inlet valve 32 is connected to the inlet pipe 40, and the other end of the second inlet valve 32 is connected to the water tank 10. Specifically, the inlet of the second inlet valve 32 is connected to the inlet pipe 40, and the outlet of the second inlet valve 32 is connected to the water tank 10. Clearly, the first inlet valve 31 and the second inlet valve 32 share a single inlet pipe 40 to supply water to both valves. The inlet pipe 40 can be connected to a tap water pipe to supply water to the valve assembly 30. Since the first inlet valve 31 is connected to the diverter valve 33 and the second inlet valve 32 is connected to the water tank 10, after water flows through the inlet pipe 40 into the first inlet valve 31 and the second inlet valve 32, the first inlet valve 31 can supply water to the diverter valve 33, and the second inlet valve 32 can replenish water to the water tank 10. In other words, the first inlet valve 31 and the second inlet valve 32 share a single inlet pipe 40, but their flow channels are independently configured.

[0048] Furthermore, the water pump 50 is installed inside the water tank 10, and the outlet of the water pump 50 is connected to the water distribution valve 33. The water distribution valve 33 is provided with a first outlet 331 and a second outlet 332, and the water distribution valve 33 selectively conducts the first outlet 331 and / or the second outlet 332. The water pump 50 is installed inside the water tank 10 and connected to the water distribution valve 33, that is, the water flow in the water tank 10 can be transmitted to the water distribution valve 33 through the water pump 50. In other words, the water distribution valve 33 has two water inlets: one is for the operation of the first water inlet valve 31 and the water distribution valve 33, and the other is for the water pump 50 to draw water from the water tank 10 to supply water to the water distribution valve 33. Furthermore, the water distribution valve 33 is provided with a first outlet 331 and a second outlet 332, and selectively conducts the first outlet 331 and / or the second outlet 332. That is, when the water distribution valve 33 drains water, it can be discharged through the first outlet 331 and / or the second outlet 332.

[0049] In a specific application scenario, the flushing device is installed inside a smart toilet. The first water outlet 331 can be connected to the side flush port of the smart toilet via a pipe, and the second water outlet 332 can be connected to the bottom flush port of the smart toilet via a pipe. Since the water distribution valve 33 can selectively open the first water outlet 331 and / or the second water outlet 332, when flushing the smart toilet, the first water outlet 331 can be opened and the second water outlet 332 can be closed to complete the side flush of the smart toilet through the first water outlet 331, or the second water outlet 332 can be opened and the first water outlet 331 can be closed to complete the bottom flush of the smart toilet through the second water outlet 332, or both the first water outlet 331 and the second water outlet 332 can be opened simultaneously to complete both the bottom flush and the side flush of the smart toilet through the first water outlet 331 and the second water outlet 332, that is, the bottom flush and the side flush are performed simultaneously. When flushing the smart toilet through the first outlet 331, the water pump 50 may not operate. However, when flushing through the second outlet 332, since the smart toilet requires relatively high water pressure for bottom flushing, the water pump 50 can operate to draw water from the tank 10 to supply water to the diversion valve 33 via the inlet pipe 40, thereby increasing the drainage water pressure at the second outlet 332. Clearly, the operation of the water pump 50 is determined by the water pressure in the inlet pipe 40. For example, when side flushing the smart toilet through the first outlet 331, if the water pressure is insufficient, the water pump 50 can also be activated to supply water to the diversion valve 33, thereby increasing the water pressure during side flushing.

[0050] In an optional embodiment, the water inlet pipe 40 can be connected to the first water inlet valve 31 and the second water inlet valve 32 via the bottom of the water tank 10. That is, the water inlet pipe 40 can be arranged relative to the axis of the water tank 10, and the water inlet pipe 40 is perpendicular to the plane where the water level is located in the water tank 10. The floating component 20 is sleeved on the outer wall of the water inlet pipe 40, that is, the floating component 20 is slidably arranged relative to the water inlet pipe 40. When the water flow in the water tank 10 rises and falls, it can drive the floating component 20 to rise and fall. A linkage mechanism 60 is provided between the floating component 20 and the second water inlet valve. Specifically, the linkage mechanism 60 is movably connected to the floating component 20 and the second water inlet valve 32. The linkage mechanism 60 controls the opening and closing state of the second water inlet valve 32, that is, the opening and closing state of the second water inlet valve 32 can be controlled by the rising and falling of the floating component 20.

[0051] In this embodiment, as Figure 2 As shown, the flushing device also includes a control mechanism 73, which is mounted on the water distribution valve 33. Specifically, the control mechanism 73 can drive the linkage mechanism 60 to operate according to the working state of the water distribution valve 33, thereby controlling the opening or closing of the second water inlet valve 32. That is, when the first water inlet valve 31 is working, i.e., when the first water inlet valve 31 is draining water, the control mechanism 73 can drive the linkage mechanism 60 to operate, thereby controlling the second water inlet valve 32 to close, so as to avoid the second water inlet valve 32 operating to divert the water flow when the first water inlet valve 31 is working, resulting in insufficient drainage pressure of the water distribution valve 33. Moreover, when it is necessary to replenish water to the water tank 10, the first water inlet valve 31 is in the closed state, and the control mechanism 73 can control the connecting mechanism 60 to operate, thereby controlling the second water inlet valve 32 to close, thus avoiding the first water inlet valve 31 operating as the water distribution valve 33 to divert the water flow when replenishing water to the water tank 10. Clearly, the control mechanism 73 can control the closing of the second inlet valve 32 according to the working state of the water distribution valve 33. In other words, the control mechanism 73 can selectively open and close the first inlet valve 31 and the second inlet valve 32 by controlling the action of the linkage mechanism 60, thereby preventing water flow diversion. Specifically, the control mechanism 73's control of the linkage mechanism 60 can be represented by the connection state between the linkage mechanism 60 and the second inlet valve 32, thereby controlling the opening and closing state of the second inlet valve 32.

[0052] In this embodiment, the control mechanism 73 controls the action of the linkage mechanism 60, allowing the linkage mechanism 60 and the second inlet valve 32 to be in different connection states, thereby controlling the opening and closing state of the second inlet valve 32. Specifically, when the first inlet valve 31 needs to be open, the control mechanism 73 can control the linkage mechanism 60 to abut against the second inlet valve 32, thus controlling the second inlet valve 32 to be closed. When water needs to be added to the water tank 10, the first inlet valve 31 is closed, and the control mechanism 73 can control the linkage mechanism 60 to disengage from the second inlet valve 32, thus allowing the second inlet valve 32 to open. Clearly, the control mechanism 73 and the linkage mechanism 60 can selectively open the first inlet valve 31 and the second inlet valve 32. When the water distribution valve 33 is working and flushing is required, the first inlet valve 31 is open, and the control mechanism 73 controls the linkage mechanism 60 to abut against the second inlet valve 32, thereby controlling the second inlet valve 32 to close, allowing water to flow through the water distribution valve 33 to complete the flushing. Specifically, when the water distribution valve 33 needs to flush, the water level in the water tank 10 is at a high level. At this time, the floating component 20 floats up under the action of the buoyancy of the water flow. When the water distribution valve 33 opens the first inlet valve 31, the control mechanism 73 can fix the floating component 20 to prevent it from falling after the water level in the water tank 10 drops. It also prevents the floating component 20 from driving the linkage mechanism 60 to fall when it falls, thereby controlling the linkage mechanism 60 to abut against the second inlet valve 32 so that the second inlet valve 32 is closed. When the water distribution valve 33 needs to be flushed, the first inlet valve 31 opens to supply water to the water distribution valve 33, and the water pump 50 can draw water from the water tank 10 to supply water to the water distribution valve 33. After the water is drained through the water distribution valve 33, the water in the water tank 10 is discharged. Since the water distribution valve 33 fixes the floating component 20 to prevent the floating component 20 from falling, the second inlet valve 32 is closed, thus preventing the second inlet valve 32 from opening to replenish water to the water tank 10 when the time valve is flushed. When the second inlet valve 32 needs to replenish water to the water tank 10, the control mechanism 73 can control the linkage mechanism to activate the second inlet valve 32. Specifically, the control mechanism 73 can disengage from the floating component 20. Under its own weight, the floating component 20 can descend to the water level in the water tank 10. When the floating component 20 descends, it drives the linkage mechanism 60 to activate, thereby disengaging the linkage mechanism 60 from the second inlet valve 32 and opening the second inlet valve 32. Since the first inlet valve 31 is closed, water in the inlet pipe 40 can replenish water to the water tank 10 through the second inlet valve 32, while also preventing the diversion of water from the first inlet valve 31. In other words, the control mechanism 73 selectively activates the first inlet valve 31 and the second inlet valve 32 through the linkage mechanism 60, avoiding water diversion and thus preventing insufficient water pressure when flushing the diversion valve 33.

[0053] In an optional embodiment, when drainage is required through the first outlet 331 and / or the second outlet 332, the first inlet valve 31 is opened, and the control mechanism 73 controls the second inlet valve 32 to close via the linkage mechanism 60, thereby allowing water to flow through the inlet pipe 40 and the first inlet valve 31 to the diverter valve 33 to complete the drainage work. During drainage, the water pump 50 can draw water from the water tank 10 to supply water to the diverter valve 33 via the inlet pipe 40, thereby increasing the water pressure during drainage. When water needs to be replenished in the water tank 10, after the water level in the water tank 10 drops, the floating component 20 can descend to the position of the water level in the water tank 10, thereby disengaging the linkage mechanism 60 from the second inlet valve 32, thus opening the second inlet valve 32, and allowing water to flow through the inlet pipe 40 to replenish the water tank 10 via the second inlet valve 32.

[0054] By means of the above method, by setting a floating component 20 in the water tank 10 and a linkage mechanism 60 connecting the floating component 20 and the second inlet valve 32, the control mechanism 70 can drive the linkage mechanism 60 to operate according to the working state of the water valve 33, so as to control the opening and closing state of the second inlet valve 32. This allows for selective conduction of the first inlet valve 31 and the second inlet valve 32, avoiding the diversion of water flow by multiple water channels when the flushing device is working. This effectively improves the applicability of the flushing device. Furthermore, the second inlet valve 32 can be used to replenish water to the water tank 10, and water can be drained through the first outlet 331 and / or the second outlet 332, effectively improving the multifunctionality of the flushing device. In addition, the flushing device is integrated, effectively reducing the volume occupied by the flushing device.

[0055] In an optional embodiment, such as Figure 3 As shown, isolation components 34 are provided inside the first inlet valve 31 and the second inlet valve 32 to control the connection status between the first inlet valve 31 and the second inlet valve 32 and the outside world, thereby preventing siphoning. The isolation component 34 includes a first isolation valve core 311 and a second isolation valve core 321. The first isolation valve core 311 is located inside the first inlet valve 31, and the second isolation valve core 321 is located inside the second inlet valve 32. The connection or disconnection status of the first inlet valve 31 and the second inlet valve 32 with the outside world is controlled by the first isolation valve core 311 and the second isolation valve core 321, respectively. Since the first isolation valve core 311 and the second isolation valve core 321 are respectively located in the independent first inlet valve 31 and the second inlet valve 32, the connection status between the first inlet valve 31 and the second inlet valve 32 and the outside world is controlled by the first isolation valve core 311 and the second isolation valve core 321, respectively.

[0056] When the inlet pipe 40 supplies water to the diversion valve 33 through the first inlet valve 31, the water flow through the inlet pipe 40 can generate buoyancy on the first isolation valve core 311 under the action of the water flow, thereby lifting the first isolation valve core 311 to isolate the first inlet valve 31 from the outside. After the water flow in the first inlet valve 31 is transmitted to the diversion valve 33 and discharged through the diversion valve 33, under the action of atmospheric pressure and the weight of the first isolation valve core 311 itself, the water flow in the first isolation valve core 311 and the diversion valve 33 gradually decreases until the water flow in the diversion valve 33 is completely discharged. At this time, the decrease of the first isolation valve core 311 connects the first inlet valve 31 to the outside, making the air pressure in the first inlet valve 31 the same as the outside, thereby avoiding siphoning and contaminating the tap water in the inlet pipe 40. The water pump 50 is connected to the water distribution valve 33 via a pipeline. Specifically, when the water pump 50 pumps water, the water flow must pass through the first inlet valve 31, which is also the first isolation valve core 311. This means that the first isolation valve core 311 can also achieve pressure balance during pumping, thus preventing siphoning. When the second inlet valve 32 replenishes water to the water tank 10, the second isolation valve core 321 operates in the same way as the first isolation valve core 311, which will not be elaborated further here. A one-way valve (not shown in the figure) is provided at the connection between the water pump 50 and the water distribution valve 33. This one-way valve allows water flow from the water pump 50 to the water distribution valve 33, but prevents water flow from the water distribution valve 33 from flowing to the water pump 50.

[0057] In this embodiment, when water flows through the first inlet valve 31, the channel connecting the first isolation valve core 311 and the first inlet valve 31 to the outside is disconnected, thereby isolating the first inlet valve 31 from the outside. Specifically, as shown... Figure 1 As shown, the first isolation valve core 311 is movably connected within the first inlet valve 31, and an overflow hole 341 is formed at one end of the first inlet valve 31. When the first isolation valve core 311 fails to isolate the first inlet valve 31 from the outside, that is, when the first isolation valve core 311 cannot isolate the first inlet valve 31 from the outside, water can overflow into the water tank 10 through the overflow hole 341. Correspondingly, the second inlet valve 32 is also provided with an overflow hole 341.

[0058] In an optional embodiment, such as Figure 3 and Figure 10 As shown, the water distribution valve 33 includes a valve body 335, a drive component 76, and a water distribution valve core 333. The drive component 76 is disposed at one end of the valve body 335, and the output end of the drive component 76 is connected to the water distribution valve core 333 and the control mechanism 73. Figure 4As shown, the water distribution valve 33 also includes an end cap 70, which is detachably connected to the valve body 335, thereby forming a cavity for water flow within the water distribution valve 33. A drive element 76 is located at one end of the valve body 335, specifically at the end of the end cap 70 away from the valve body 335. The drive element 76 can be a motor or other power-providing mechanism; this application does not specify a particular type. The water distribution valve 33 contains a water distribution valve core 333, and the output end of the drive element 76 is connected to the water distribution valve core 333. Specifically, the output end of the drive element 76 can penetrate the end cap 70 and connect to the water distribution valve core 333. Figure 5 As shown, the water distribution valve core 333 is provided with a baffle 334, which is fitted against the inner wall of the water distribution valve 33 to selectively block the first outlet 331 or the second outlet 332. The water distribution valve core 333 can rotate within the water distribution valve 33 under the drive of the drive member 76. The baffle 334 on the water distribution valve core 333 fits against the inner wall of the water distribution valve 33, so that when the drive member 76 drives the water distribution valve core 333 to rotate, the baffle 334 can be driven to rotate against the inner wall of the water distribution valve 33 to different positions. Specifically, the inner wall of the water distribution valve 33 can be arc-shaped, and the corresponding contact surface between the baffle 334 and the inner wall of the water distribution valve 33 is also arc-shaped, so that when the baffle 334 rotates, it can abut against the inner wall of the water distribution valve core 333. The end cap 70 is provided with a retaining claw 75, so that when the end cap 70 is placed at one end of the water distribution valve 33, the end cap 70 can be fixed to the valve body of the water distribution valve 33 by the retaining claw 75. The end cap 70 is provided with a drive mounting base 761 for mounting the drive component 76.

[0059] In this embodiment, as Figure 4 and Figure 5As shown, a rotating hole (not shown) can be formed in the water distribution valve 33. One end of the rotating shaft of the water distribution valve core 333 can be inserted into the rotating hole, and the other end can be fixedly connected to the output end of the drive component 76, thereby completing the drive rotation of the water distribution valve core 333. A support column 3332 can be formed on the rotating shaft of the water distribution valve core 333, and a snap-fit ​​column 3342 can be formed on the baffle 334. The baffle 334 can be snapped onto the support column 3332 through the snap-fit ​​column 3342 for fixation, thereby fixing the baffle 334 to the rotating shaft of the water distribution valve core 333. A limit block 3331 is formed on the rotating shaft of the water distribution valve core 333. The end cap 70 is located at one end of the water distribution valve 33, forming a water supply cavity with the valve body 335 of the water distribution valve 33. The end cap 70 has a limiting rib 74 corresponding to the limiting block 3331. When the driving member 76 drives the water distribution valve core 333 to rotate, the limiting rib 74 on the end cap 70 abuts against the limiting block 3331 on the water distribution valve core 333, thereby limiting the rotation angle of the water distribution valve core 333. An adhesive layer 3341 is formed on the side of the baffle 334 that is in contact with the inner wall of the water distribution valve 33. This effectively reduces friction between the inner wall of the water distribution valve 334 and the baffle 334 when the baffle 334 rotates within the water distribution valve 33, thus effectively improving the service life of the flushing device.

[0060] When flushing is required through the diversion valve 33, the driving component 76 drives the diversion valve core 333 to rotate, thereby rotating the baffle 334. The baffle 334 can block the first outlet 331 and / or the second outlet 332, thus diverting the water flow. Specifically, when the diversion valve 33 needs to drain water through the first outlet 331, the driving component 76 drives the diversion valve core 333 to rotate, causing the baffle 334 to abut against the second outlet 332 to block it. At this time, the second outlet 332 is closed, the first outlet 331 is open, and the water in the diversion valve 33 is discharged through the first outlet 331. Correspondingly, when the second outlet 332 needs to drain water, the baffle 334 can abut against the first outlet 331 to block it, allowing the water in the diversion valve 33 to be discharged through the second outlet 332. When it is necessary for the first outlet 331 and the second outlet 332 to drain water simultaneously, the drive unit 76 can drive the water distribution valve core 333 to rotate, so that the baffle 334 is located between the first outlet 331 and the second outlet 332, so that the baffle 334 blocks part of the first outlet 331 and part of the second outlet 332, thereby allowing the water in the water distribution valve 33 to be discharged through the first outlet 331 and the second outlet 332.

[0061] In an optional embodiment, such as Figure 2 and Figure 9As shown, the first inlet valve 31 is a pilot valve. The valve body of the first inlet valve 31 has a first pilot hole 312. The flushing device also includes a pilot control valve 72, which is driven by the control mechanism 73 of the water distribution valve. The pilot control valve 72 controls the opening and closing of the first pilot hole 312 to control the opening and closing state of the first inlet valve 31. Controlling the opening and closing state of the first inlet valve 31 can be represented as follows: when the pilot control valve 72 is in contact with the first pilot hole 312, the first inlet valve 31 is closed; when the pilot control valve 72 is disengaged from the first pilot hole 312, the first inlet valve 31 is open. Figure 6 and Figure 8 As shown, the end cap 70 near the water distribution valve 33 is provided with a support member 71. A pilot control valve 72 is movably mounted on the support member 71. The pilot control valve 72 includes a piston rod 721, an elastic member 722, a rubber member 723, and a snap-fit ​​member 724. The piston rod 721 near the water distribution valve 33 is provided with the rubber member 723, and the other end is provided with the snap-fit ​​member 724. One end of the elastic member 722 abuts against one side end face of the support member 71, and the other end abuts against the end of the piston rod 721 away from the snap-fit ​​member 724. Figure 9 As shown, the first inlet valve 31 has a first pilot hole 312, which is movably connected to the rubber component 723. The pilot control valve 72 is movably mounted on the support member 71. Specifically, the support member 71 has a through hole 711 and a notch 712 communicating with the through hole 711. An annular groove 725 is provided on the piston rod 721. The annular groove 725 on the piston rod 721 can be engaged in the through hole 711 through the notch 712, thereby allowing the piston rod 721 to move within the through hole 711.

[0062] In this embodiment, as Figure 7As shown, the control mechanism 73 is mounted on the end cover 70, specifically within the gap formed between the drive mounting base 761 and the support member 71. The control mechanism 73 is connected to the output end of the drive member 76. The control mechanism 73 includes a switching disk 731, which is movably connected to a snap-fit ​​member 724. The connection state between the switching disk 731 and the snap-fit ​​member 724 controls the connection state between the pilot control valve 72 and the first pilot hole 312, thereby controlling the opening and closing state of the first water inlet valve 31. The control mechanism 73 is connected to the output end of the drive member 76, meaning that when the drive member 76 drives the water distribution valve core 333 to rotate, it can synchronously drive the control mechanism 73 to rotate. The control mechanism 73 is semi-circular, and an inclined surface 733 is provided at the end of the semi-circular control mechanism 73, which is located away from the water distribution valve 33. When the drive unit 76 drives the control mechanism 73 to rotate, the switching disk 731 of the control mechanism 73 can abut against the snap-fit ​​part 724 on the piston rod 721, thereby causing the piston rod 721 to move away from the end away from the water distribution valve 33, thereby causing the rubber part 723 on the piston rod 721 to disengage from the first pilot hole 312 on the first water inlet valve 31, so as to open the first water inlet valve 31 to supply water to the water distribution valve 33. When the drive unit 76 drives the control mechanism 73 to rotate, the inclined surface 733 on the switching disk 731 can abut against the locking part 724 on the piston rod 721. When the switching disk 731 continues to rotate under the action of the drive unit 76, the locking part 724 on the piston rod 721 can slide relative to the inclined surface 733 and slide along the inclined surface 733 to the side end face of the switching disk 731 away from the water distribution valve 33. At this time, because the piston rod 721 moves away from the water distribution valve 33 under the drive of the switching disk 731, the rubber part 723 on the piston rod 721 disengages from the first pilot hole 312 on the first water inlet valve 31, thereby opening the first water inlet valve 31 to supply water to the water distribution valve 33. When it is necessary to close the inlet valve, the drive member 76 drives the control mechanism 73 to rotate in the opposite direction. Under the action of the elastic member 722, the piston rod 721 slides along the inclined surface 733 of the switching disk 731 until it disengages from the switching disk 731. Under the action of the elastic member 722, the rubber part 723 on the piston rod 721 abuts against the first pilot hole 312 of the first inlet valve 31, thereby causing the first inlet valve 31 to close and stop supplying water to the water distribution valve 33.

[0063] The diameter of the first pilot hole 312 is preferably 0.8mm-1.2mm. According to the pressure formula F=P*S, where F is the pressure, S is the area of ​​force application, and P is the pressure. That is, the smaller the area of ​​force application of the first pilot hole 312, the lower the pressure of the water flow on the rubber component 723, and correspondingly, the smaller the elastic force required by the elastic component 722. Therefore, when the diameter of the first pilot hole 312 is within the above range, the opening and closing effect of the first water inlet valve 31 controlled by the pilot control valve 72 is effectively guaranteed.

[0064] In an optional embodiment, such as Figure 2 As shown, when the water distribution valve 33 needs to drain water through the first outlet 331 and / or the second outlet 332, the output end of the drive member 76 can drive the control mechanism 73 and the water distribution valve core 333 to rotate along the first direction 91, for example, clockwise or counterclockwise along the axis of the water distribution valve 33. This application takes instantaneous rotation along the axis of the water distribution valve 33 as an example, that is, the direction in which the second outlet 332 moves toward the first outlet 331. The inclined surface 733 on the switching disk 731 abuts against the locking member 724 on the piston rod 721, so that the locking member 724 slides along the inclined surface 733 to the end face of the switching disk 731, so that the rubber part 723 on the piston rod 721 moves away from the first pilot hole 312, thereby opening the first water inlet valve 31, and the water flow in the water inlet pipe 40 can enter the water distribution valve 33 through the first water inlet valve 31. Furthermore, while the drive unit 76 drives the control mechanism 73 to rotate, it also drives the water distribution valve core 333 to rotate synchronously. The baffle 334 on the water distribution valve core 333 can block the first outlet 331 and / or the second outlet 332, thereby allowing water to flow out through the water distribution valve 33. At the same time, when the water distribution valve 33 is draining water, the water pump 50 can be started to draw water from the water tank 10 and transfer it to the water distribution valve 33. After the water distribution valve 33 has drained, the drive component 76 can drive the control mechanism 73 and the water distribution valve core 333 to rotate in the opposite direction of the first direction 91. Under the action of the elastic component 722, the locking component 724 on the piston rod 721 can slide along the inclined surface 733 on the switching disk 731 until the switching disk 731 disengages from the locking component 724. Under the action of the elastic component 722, the rubber component 723 on the piston rod 721 abuts against the first pilot hole 312, thereby blocking the first pilot hole 312. The first water inlet valve 31 closes and stops supplying water to the water distribution valve 33. At this time, the water distribution valve core 333 returns to its initial position. The initial position of the water distribution valve 33 can be that the baffle 334 is located on the same side as the first outlet 331 and the second outlet 332, and the first outlet 331 and the second outlet 332 are not blocked.

[0065] In an optional embodiment, such as Figure 10 and Figure 11 As shown, the second inlet valve 32 is a pilot valve, and a second pilot hole 323 is provided on the second inlet valve 32. The linkage mechanism 60 includes a connector 64 and a sealing gasket 61. One end of the connector 64 is movably connected to the floating assembly 20, and the other end is provided with the sealing gasket 61. Figure 7As shown, the control mechanism 73 includes a driveable locking member 732. The locking member 732 is configured such that: when it engages with the floating assembly 20, it forces the floating assembly 20 to seal the second pilot hole 323 via the connector 64, thereby closing the second water inlet valve 32; when it disengages from the floating assembly 20, the floating assembly 20 can float freely, allowing the sealing gasket 61 to disengage from the second pilot hole 323, thereby opening the second water inlet valve 32. The locking member 732 is located on the end face of the switching disk 731 away from the water distribution valve 33. The second water inlet valve 32 has a second pilot hole 323 and a rotating seat 322. Figure 11 As shown, one end of the connector 64 is rotatably connected to the rotating seat 322 and extends beyond the rotating seat 322, while the other end is connected to the floating assembly 20. A sealing gasket 61 is provided at the end of the connector 64 near the rotating seat 322, and the sealing gasket 61 is movably connected to the second pilot hole 323.

[0066] like Figure 12 and Figure 13 As shown, the floating assembly 20 includes a float 21 and a floating seat 22. The floating seat 22 is sleeved on the outside of the float 21. The float 21 is provided with a hook 211, which is movably connected to a locking member 732. The connection state between the hook 211 and the locking member 732 can control the state of the connector 64, thereby controlling the connection state between the sealing gasket 61 and the second pilot hole 323. Specifically, a limiting groove 212 is formed on the end face of the float 21 near the hook 211. A first column 62 is formed at the first end of the connector 64, which is slidably disposed in the limiting groove 212. A second column 63 is formed at the second end of the connector 64, and the second end of the connector 64 extends beyond the second column 63. The second column 63 is rotatably connected to a rotating seat 322 on the second inlet valve 32. The connector 64 can be formed by splicing two arc segments, allowing the linkage mechanism 60 to fit against the sidewalls of the second inlet valve 32 and the float 21, thereby effectively reducing the space occupied by the linkage mechanism 60. When the float 21 floats on the water flow in the water tank 10, the buoyancy of the float 21 must be greater than the pressure exerted by the second inlet valve 32 on the sealing gasket 61 through the second pilot hole 323. Specifically, the diameter of the second pilot hole 323 can be the same as that of the first pilot hole 312, or it can be set according to requirements; this application does not impose specific limitations here.

[0067] In this embodiment, a locking member 732 is provided on the side of the switching disk 731 away from the water distribution valve 33. The locking member 732 can be movably connected to the hook 211 on the float 21. When the hook 211 is locked on the locking member 732, the float 21 can be prevented from descending under its own weight, thereby causing the sealing gasket 61 on the linkage mechanism 60 to disengage from the second pilot hole 323 of the second water inlet valve 32, thereby opening the second water inlet valve 32 and preventing the second water inlet valve 32 from supplying water to the water tank 10 and thus diverting the water flow when the water distribution valve 33 is draining water. When the second inlet valve 32 needs to be opened, the locking member 732 disengages from the hook 211 on the float 21, so that the float 21 descends under the action of gravity, and drives the end of the linkage mechanism 60 with the first column 62 to descend. That is, the first column 62 of the linkage mechanism 60 slides in the limiting groove 212 of the float 21, so that the linkage mechanism 60 rotates along the second column 63, so that the end of the linkage mechanism 60 with the sealing gasket 61 tilts up, so that the sealing gasket 61 disengages from the second pilot hole 323, thereby opening the second inlet valve 32. The water in the inlet pipe 40 can enter the water tank 10 through the second inlet valve 32 to replenish the water tank 10.

[0068] In an optional embodiment, when the water distribution valve 33 needs to drain water, the drive member 76 can drive the control mechanism 73 and the water distribution valve core 333 to rotate along the first direction 91, thereby causing the locking member 732 on the control mechanism 73 to engage with the hook 211 to fix the float 21. Since the locking member 732 on the control mechanism 73 is engaged with the hook 211, the sealing gasket 61 on the linkage mechanism 60 abuts against the second pilot hole 323, the second water inlet valve 32 is in the closed state, and the switching disk 731 drives the pilot control valve 72 away from the first pilot hole 312. This causes the first inlet valve 31 to open, allowing water from the inlet pipe 40 to enter the diverter valve 33. The drive unit 76 drives the diverter valve core 333 to rotate, and the baffle 334 on the diverter valve core 333 can block the first outlet 331 and / or the second outlet 332, thereby allowing water to be discharged through the diverter valve 33. At the same time, when the diverter valve 33 is draining water, the water pump 50 can be started to draw water from the water tank 10 and transfer it to the diverter valve 33 to cooperate with the inlet pipe 40 to supply water to the diverter valve 33 and increase the water pressure when the diverter valve 33 is draining water.

[0069] After the water distribution valve 33 has finished draining, the drive member 76 can drive the control mechanism 73 and the water distribution valve core 333 to rotate in the opposite direction of the first direction 91, thereby causing the switching disc 731 to disengage from the snap-fit ​​member 724 on the piston rod 721. As a result, under the action of the elastic member 722, the rubber member 723 on the piston rod 721 abuts against the first pilot hole 312, and the first water inlet valve 31 is closed. Furthermore, the drive component 76 drives the control mechanism 73 to rotate, causing the locking component 732 on the switching disk 731 to disengage from the hook 211. As the water level in the water tank 10 drops, the float 21 descends to the water level in the water tank 10 under its own weight. As the float 21 descends, the first column 62 of the linkage mechanism 60 descends under the drive of the float 21, causing the second column 63 of the linkage mechanism 60 to rotate along the rotating seat 322. This causes the end of the linkage mechanism 60 with the sealing gasket 61 to tilt upwards, that is, away from the second pilot hole 323, thereby causing the second water inlet valve 32 to open. At this time, the first water inlet valve 31 is closed and the second water inlet valve 32 is open. The water flow in the water inlet pipe 40 can enter the water tank 10 through the second water inlet valve 32 to replenish the water level in the water tank 10 to the preset water level position.

[0070] In this embodiment, as Figure 25 As shown, when water is added to the water tank 10, the locking part 732 on the control mechanism 73 disengages from the hook 211 on the float 21. The float 21 descends under its own weight, causing the linkage mechanism 60 to rotate on the rotating seat 322 along the second direction 92. That is, the second column 63 on the linkage mechanism 60 rotates on the rotating seat 322, causing the sealing gasket 61 on the linkage mechanism 60 to disengage from the second pilot hole 323. The second inlet valve 32 opens, and the water in the inlet pipe 40 can enter the water tank 10 through the second inlet valve 32. After the water level in the water tank 10 rises, the float 21 rises under the action of buoyancy, causing the linkage mechanism 60 to rotate in the opposite direction along the second direction 92 on the rotating seat 322. This causes the sealing gasket 61 on the linkage mechanism 60 to abut against the second pilot hole 323, the second inlet valve 32 closes, and the water flow in the inlet pipe 40 stops, thus replenishing the water tank 10.

[0071] In an optional embodiment, such as Figure 13 and Figure 15 As shown, a floating element 23 is provided at the end away from the float 21. One end of the floating element 23 has a boss 231, and the other end forms a frustum 232. A slot 221 and a drain hole 222 communicating with the slot 221 are formed on the floating seat 22. The boss 231 is movably disposed within the slot 221 and is limited by the boss 231. The connection state between the floating element 23 and the slot 221 controls the opening and closing state of the drain hole 222. Combined with... Figure 14As shown, the floating component 23 is specifically a float, meaning that the floating component 23 can float under the buoyancy of the water flow in the water tank 10. The floating component 23 is slidably mounted on the floating seat 22, and the floating component 23 can be limited by the boss 231 to prevent the floating component 23 from detaching from the floating seat 22. When there is water flow in the floating seat 22, the water flow in the floating seat 22 also exerts water pressure on the floating component 23, and the floating component 23 sinks under its own weight. That is to say, when there is no water flow in the floating seat 22, the floating component 23 floats under the buoyancy of the water flow in the water tank 10, so that the frustum 232 on the floating component 23 is located in the slot 221, thereby blocking the drain hole 222. When water flows within the floating seat 22, and the water in the water tank 10 descends to a certain position (e.g., to a certain extent), the buoyancy of the water in the water tank 10 on the floating member 23 is less than the sum of the pressure exerted by the water in the floating seat 22 on the floating member 23 and the weight of the floating member 23 itself. At this point, the floating member 23 begins to descend. That is, the water in the floating seat 22 exerts water pressure on the floating member 23, and the floating member 23 descends under its own weight. This causes the frustum 232 on the floating member 23 to disengage from the slot 221 on the floating seat 22, thereby connecting the drain hole 222 on the floating seat 22 with the interior of the water tank 10. The water in the floating seat 22 can then be transferred to the water tank 10 through the drain hole 222. In other words, the action of the floating member 23 effectively slows down the rate at which water enters the floating seat 22. In this embodiment, the floating seat 22 is sleeved on the outside of the float 21. Specifically, a groove 213 is formed on the outer wall of the float 21, and a slide rail 223 is formed on the corresponding inner wall of the floating seat 22. The slide rail 223 cooperates with the groove 213, so that the float 21 can slide relative to the floating seat 22. Thus, the mutual cooperation between the slide rail 223 and the groove 213 can further limit the position of the float 21 and the floating seat 22.

[0072] In an optional embodiment, such as Figure 16As shown, the flushing device also includes a water supply pipe 41. One end of the water supply pipe 41 is connected to the second water inlet valve 32, and the other end is connected to the water tank 10. The water distribution valve 33 is provided with a first water outlet pipe 42 and a second water outlet pipe 43 that are respectively connected to the first water outlet 331 and the second water outlet 332. The first water outlet pipe 42, the second water outlet pipe 43 and the water supply pipe 41 are arranged through the floating component 20. The water supply pipe 41 can be fitted to the water inlet pipe 40, that is, the axial direction of the water supply pipe 41 can be parallel to the axial direction of the water inlet pipe 40, so that the floating component 20 can be sleeved on the outer wall of the water supply pipe 41 and the water inlet pipe 40. Since the cross-section of the water supply pipe 41 and the water inlet pipe 40 is irregular, the floating component 20 can be limited by the water supply pipe 41 and the water inlet pipe 40, thereby preventing the floating component 20 from rotating inside the water tank 10, which would cause the position of the hook 211 on the float 21 to shift, and cause the locking part 732 on the control mechanism 73 to fail to cooperate with the hook 211. Correspondingly, the water distribution valve 33 is provided with a first water outlet pipe 42 and a second water outlet pipe 43 that are respectively connected to the first water outlet 331 and the second water outlet 332. The first water outlet pipe 42 and the second water outlet pipe 43 are arranged through the floating component 20. That is, the cross-section of the first water outlet pipe 42, the second water outlet pipe 43, the water inlet pipe 40 and the water replenishment pipe 41 is irregularly shaped, thereby effectively preventing the floating component 20 from shifting in the water tank 10.

[0073] Specifically, such as Figure 13 As shown, a first mounting position 224 is formed on the floating seat 22, and the first water outlet pipe 42 and the second water outlet pipe 43 are located in the first mounting position 224. The float 21 seat also has a second mounting position 225 and a third mounting position 226 for installing the water inlet pipe 40 and the water supply pipe 41, respectively.

[0074] In an optional embodiment, such as Figure 17As shown, a hydraulic sensor 44 and a control component (not shown) are installed inside the water inlet pipe 40. The hydraulic sensor 44 is installed inside the water inlet pipe 40 to detect water pressure. The control component is electrically connected to the hydraulic sensor 44, the drive component 76 of the water distribution valve 33, and the water pump 50, and is used to control the working state of the drive component 76 and the water pump 50 according to the signal from the hydraulic sensor 44. A flow limiting component (not shown) is also installed inside the water inlet pipe 40. Since the water inlet pipe 40 is connected to the tap water pipe, when the tap water pressure is high, the flow of tap water entering the water inlet pipe 40 can be limited by the flow limiting component, thus avoiding excessive noise caused by excessive water pressure. Furthermore, the flow limiting component inside the water inlet pipe can limit the water flow when the water pressure is high, thereby effectively reducing the water flow entering the first water inlet valve 31 and the second water inlet valve 32. A hydraulic sensor 44 is installed in the water inlet pipe 40. The hydraulic sensor 44 can detect the water flow and water pressure of tap water entering the water inlet pipe 40, thereby determining whether the water pump 50 needs to be turned on to supply water to the water inlet pipe 40 when the water distribution valve 33 is flushed.

[0075] In this embodiment, the control component is electrically connected to the drive unit 76 and the water pump 50 to control the working state of the water pump 50 and the drive unit 76. That is, when the water distribution valve 33 needs to flush and the water tank 10 needs to be replenished, the working state of the water pump 50 and the drive unit 76 can be controlled by the control component to complete the corresponding flushing and replenishment work.

[0076] In an optional embodiment, such as Figure 18 As shown, the water flow path inside the flushing device is as follows: tap water enters the first inlet valve 31 and the second inlet valve 32 through the inlet pipe 40, and then enters the water tank 10 through the second inlet valve 32 to replenish the water tank 10. When flushing is required through the diversion valve 33, the tap water flows through the first inlet valve 31 into the diversion valve 33, and simultaneously, the water pump 50 draws water from the water tank 10 into the diversion valve 33. That is, the water pump 50, in conjunction with the first inlet valve 31, supplies water to the diversion valve 33, and the water in the diversion valve 33 is discharged through the first outlet 331 / or the second outlet 332. It can be understood that after the water in the water tank 10 is drawn by the water pump 50 and discharged through the diversion valve 33, the second inlet valve 32 can be opened again to replenish the water tank 10.

[0077] This application also provides a smart toilet, such as Figure 19 As shown, a flushing device including any of the embodiments described above.

[0078] In one optional embodiment, the smart toilet includes a housing 80, on which a fixing member 11 is provided. A slot 13 is provided on the outer side wall of the water tank 10, and the slot 13 is inserted into and fixed to the fixing member 11. The fixing member 11 is a movable part, meaning it can be positioned at any location on the housing 80. Therefore, when the water tank 10 is fixed to the housing 80 via the fixing member 11, it can be installed in any type of smart toilet. Specifically, when fixing the water tank 10, the fixing member 11 can be fixed to the housing 80, and one end of the fixing member 11 has a bent portion (not shown). The slot 13 is formed on the outer side wall of the water tank 10, allowing the slot 13 to be inserted into the bent portion of the fixing member 11, thereby completing the fixation of the water tank 10.

[0079] In this embodiment, combined with Figure 20 As shown, an inner wall 81 is formed inside the outer casing 80 to form a first accommodating space 82 and a second accommodating space 83 within the outer casing 80. A flushing device is disposed within the first accommodating space 82. A first nozzle 84 and a second nozzle 85 are disposed on the inner wall 81. The first nozzle 84 is disposed on the side wall of the inner wall 81 and communicates with a first water outlet pipe 42. The second nozzle 85 is disposed at the bottom of the inner wall 81 and communicates with a second water outlet pipe 43. By forming an inner wall 81 within the outer casing 80, the interior of the outer casing 80 is divided into two accommodating spaces, namely the first accommodating space 82 and the second accommodating space 83. The first accommodating space 82 is used to install external components, such as the aforementioned flushing device. The second accommodating space 83 can be specifically a sewage tank. A first nozzle 84 and a second nozzle 85 are formed on the inner wall 81. The first nozzle 84 and the second nozzle 85 are installed at different positions on the inner wall 81, that is, they communicate with different positions in the second accommodating space 83. Thus, when the flushing device flushes the second accommodating space 83, it can complete different cleaning tasks for the second accommodating space 83. Specifically, the first nozzle 84 can be set on the side wall of the inner wall 81, and the second nozzle 85 can be set on the bottom of the inner wall 81. That is, the first nozzle 84 can be a side-flushing nozzle, and the second nozzle 85 can be a bottom-flushing nozzle. That is, the first nozzle 84 can be used to flush the second accommodating space 83 from the side, and the second nozzle 85 can be used to flush the second accommodating space 83 from the bottom.

[0080] In an optional embodiment, an overflow port 12 is formed on the water tank 10, and the overflow port 12 is connected to the second accommodating space 83. That is, when the second water inlet valve 32 is damaged and continuously replenishes water to the water tank 10, the excess water in the water tank 10 can be transferred to the second accommodating space 83 through the overflow port 12.

[0081] The first nozzle 84 is connected to the first outlet 331 of the water distribution valve 33 via the first outlet pipe 42, and the second nozzle 85 is connected to the second outlet 332 of the water distribution valve 33 via the second outlet pipe 43. When side flushing is required, the baffle 334 on the water distribution valve core 333 inside the water distribution valve 33 can abut against the second outlet 332, allowing water flow within the water distribution valve 33 to pass through the first outlet 331, the first outlet pipe 42, and the first nozzle 84 to provide side flushing for the second accommodating space 83. When bottom flushing is required, the baffle on the water distribution valve core 333 inside the water distribution valve 33 can abut against the first outlet 331, allowing water flow within the water distribution valve 33 to pass through the second outlet 332, the second outlet 332, and the second nozzle 85 to provide bottom flushing for the second accommodating space 83. When it is necessary to perform bottom flushing and side flushing simultaneously, the baffle on the water distribution valve core 333 inside the water distribution valve 33 can block part of the first water outlet 331 and the second water outlet 332, so that the water flow in the water distribution valve 33 can pass through the first water outlet 331, the second water outlet 332, the first water outlet pipe 42, the second water outlet pipe 43, the first nozzle 84 and the second nozzle 85 to perform side flushing and bottom flushing in the second accommodating space 83.

[0082] In a specific application scenario, when flushing the second accommodating space 83 using a flushing device, if it is necessary to side flush the second accommodating space 83, the driving component 76 can drive the control mechanism 73 and the water distribution valve core 333 to rotate along the first direction 91, thereby causing the locking component 732 on the switching disk 731 to engage with the hook 211 on the float 21, thereby causing the sealing gasket 61 on the linkage mechanism 60 to abut against the second pilot hole 323 of the second water inlet valve 32, so that the second water inlet valve 32 is closed, and the switching disk 731 drives the pilot control valve 72 away from the first pilot hole 312 of the first water inlet valve 31, thereby causing the first water inlet valve 31 to be open. At this time, the first water inlet valve 31 is open and the second water inlet valve 32 is closed. Water in the inlet pipe 40 can enter the diversion valve 33 through the first inlet valve 31. At the same time, the diversion valve core 333 rotates along the first direction 91, and the baffle 334 on the diversion valve core 333 blocks the second outlet 332. Since the first outlet 331 is open, water can flow through the first outlet 331, the first outlet pipe 42 and the first nozzle 84 to side flush the second accommodating space 83. When the second accommodating space 83 needs to be flushed, the drive unit 76 can drive the control mechanism 73 and the water distribution valve core 333 to continue rotating along the first direction 91. The locking part 732 on the control mechanism 73 is also connected to the hook 211. The second water inlet valve 32 is closed. The switching plate 731 also drives the pilot control valve 72 away from the first pilot hole 312. The first water inlet valve 31 is turned on. The baffle 334 on the water distribution valve core 333 rotates along the first direction 91. The baffle 334 gradually moves away from the second water outlet 332 and blocks the first water outlet 331. At this time, the second water outlet 332 is turned on. Furthermore, since a large water pressure is required to flush the second accommodating space 83, the water pump 50 starts to work. The water pump 50 draws water from the water tank 10 and, together with the first inlet valve 31, transmits the water flow to the water distribution valve 33. The water flow in the water distribution valve 33 then flushes the second accommodating space 83 through the second outlet 332, the second outlet pipe 43, and the second nozzle 85.

[0083] In this configuration, when the smart toilet switches from side flushing to bottom flushing, the baffle 334 moves continuously, meaning it partially blocks the first water outlet 331 and the second water outlet 332. This allows water from the diverter valve 33 to be discharged through the first and second water outlets 331 and 332, thus enabling bottom flushing and side flushing through the second receiving space 83 formed by the first and second nozzles 84 and 85. In contrast, if simultaneous bottom flushing and side flushing are required, the baffle 334 can be controlled to stop between the first and second water outlets 331 and 332, blocking them and completing both bottom flushing and side flushing. In this case, the baffle 334 does not continuously move during the bottom flushing and side flushing process.

[0084] Furthermore, after the second accommodating space 83 is flushed through the second outlet 332, the driving component 76 can drive the water distribution valve core 333 and the control mechanism 73 to rotate in the opposite direction of the first direction 91, thereby causing the baffle 334 on the water distribution valve core 333 to disengage from the first outlet 331 and block the second outlet 332. At this time, the water flow in the water distribution valve 33 can replenish the second accommodating space 83 through the first outlet 331. After the second accommodating space 83 is replenished with water, the drive component 76 can drive the control mechanism 73 and the water distribution valve core 333 to continue rotating in the opposite direction of the first direction 91, thereby causing the switching disc 731 to disengage from the pilot control valve 72. Under the elastic force of the elastic component 722, the pilot control valve 72 blocks the first pilot hole 312, thereby closing the first water inlet valve 31. At the same time, the locking component 732 on the switching disc 731 disengages from the hook 211 on the float 21, and the float 21 descends to the water tank 10 under its own weight. When the water level in the inner water flow is at a certain position, one end of the linkage mechanism 60 descends, and the other end of the linkage mechanism 60 rotates along the second direction 92 on the rotating seat 322 of the second water inlet valve 32. The sealing gasket 61 on the linkage mechanism 60 disengages from the second pilot hole 323, thereby opening the second water inlet valve 32. At this time, the first water inlet valve 31 is closed, and the second water inlet valve 32 is open. The water flow in the water inlet pipe 40 can be transmitted to the water tank 10 through the second water inlet valve 32 and the water replenishment pipe 41 to replenish the water tank 10. When the water tank 10 is replenished, the water level in the water tank 10 rises, and the float 21 floats up under the action of buoyancy, thereby causing one end of the linkage mechanism 60 to float up. The other end of the linkage mechanism 60 rotates in the opposite direction of the second direction 92, thereby causing the sealing gasket 61 to abut against the second pilot hole 323, so that the second water inlet valve 32 closes, thereby stopping the replenishment of water to the water tank 10.

[0085] This application also provides a flushing method performed by a control component of a smart toilet as described in any of the above embodiments.

[0086] Please see Figure 26 , Figure 26 This is a schematic flowchart of the first embodiment of the control method for the flushing device of this application. It should be noted that if substantially the same result is achieved, the method of this application is not necessarily identical. Figure 26 The illustrated process sequence is limited. For example... Figure 26 As shown, the method includes the following steps:

[0087] S11: Control the drive component 76 of the water distribution valve 33 so that the water valve assembly 30 is in the state of opening the first water inlet valve 31 and closing the second water inlet valve 32, and flush the second accommodating space 83 with water through the first nozzle 84.

[0088] In this embodiment, as Figure 21 and Figure 22As shown, the control component can control the operation of the drive component 76, thereby causing the drive component 76 to drive the control mechanism 73 and the water distribution valve core 333 to rotate in the first direction 91. The rotation of the control mechanism 73 causes the locking part 732 on the switching disk 731 to engage with the hook 211 on the float 21, thereby fixing the float 21 so that the sealing gasket 61 on the linkage mechanism 60 abuts against the second pilot hole 323 of the second water inlet valve 32, and the second water inlet valve 32 is closed. Furthermore, the switching disk 731 abuts against the locking part 724 on the pilot control valve 72, thereby causing the rubber part 723 on the piston rod 721 to move away from the first pilot hole 312, thus opening the first water inlet valve 31. When the drive component 76 drives the water distribution valve core 333 to rotate, the baffle 334 on the water distribution valve core 333 rotates along the first direction 91, thereby blocking the second water outlet 332 and opening the first water outlet 331. At this time, the first water inlet valve 31 is open and the second water inlet valve 32 is closed. The water flow in the water inlet pipe 40 is transmitted to the water distribution valve 33 through the first water inlet valve 31, and flushes the second accommodating space 83 through the first water outlet 331, the first water outlet pipe 42 and the first nozzle 84, that is, the second accommodating space 83 of the smart toilet is flushed from the side.

[0089] S12: After time t1, control the water pump 50 to start and flush the second accommodating space 83 with water through the second nozzle 85, or flush the second accommodating space 83 with water through the first nozzle 84 and the second nozzle 85.

[0090] In this embodiment, after time t1, that is, after the second accommodating space 83 is side-flushed by the first nozzle 84, the control component can control the water pump 50 to start working, that is, the water pump 50 draws water from the water tank 10 to supply water to the water distribution valve 33 in conjunction with the first water inlet valve 31. Specifically, after the side flushing is completed, the control component controls the control mechanism 73 and the water distribution valve core 333 to continue rotating along the first direction 91. At this time, the locking part 732 on the switching disk 731 continues to engage with the hook 211 on the float 21, so that the sealing gasket 61 on the linkage mechanism 60 abuts against the second pilot hole 323, the second water inlet valve 32 is closed, and the locking part 724 on the switching disk 731 and the piston rod 721 continues to abut, the rubber part 723 on the piston rod 721 moves away from the first pilot hole 312, and the first water inlet valve 31 is opened.

[0091] Based on this, combined Figure 21 and Figure 23As shown, since the first inlet valve 31 is open and the second inlet valve 32 is closed, after the side flush is completed, the second accommodating space 83 of the smart toilet needs to be flushed. Since the water pressure required for the bottom flush is relatively large, the water pump 50 can be controlled to start working at this time to transfer the water flow in the water tank 10 to the water distribution valve 33 through the water pump 50. The first inlet valve 31 is open, and the water flow in the inlet pipe 40 can be transferred to the water distribution valve 33 through the first inlet valve 31. The water flow in the inlet pipe 40 can be combined with the water flow drawn by the water pump 50 at the location where the isolation component 34 is set on the first inlet valve 31, and then transferred to the water distribution valve 33. After the water flow is transmitted to the water distribution valve 33, as the water distribution valve core 333 continues to rotate in the first direction 91, the baffle 334 on the water distribution valve core 333 can block the first water outlet 331 and open the second water outlet 332, so that the water flow in the water distribution valve 33 can flush the second accommodating space 83 through the second water outlet 332 and the second nozzle 85, that is, to flush the sewage tank of the smart toilet.

[0092] In this embodiment, combined with Figure 21 and Figure 24 As shown, the second accommodating space 83 of the smart toilet can also be simultaneously flushed from the bottom and from the side. Specifically, the drive unit 76 drives the baffle 334 on the water diversion valve core 333 to be positioned between the first water outlet 331 and the second water outlet 332. That is, the baffle 334 blocks part of the first water outlet 331 and part of the second water outlet 332. The water flow in the water diversion valve 33 can then flush the second accommodating space 83 from the side through the first water outlet 331, the first water outlet pipe 42, and the first nozzle 84. At the same time, the water flow in the water diversion valve 33 can also flush the second accommodating space 83 from the bottom through the second water outlet 332, the second water outlet pipe 43, and the second nozzle 85.

[0093] S13: After time t2, the control component controls the water pump 50 to stop working and flushes the second accommodating space 83 with water through the first nozzle 84.

[0094] In an optional embodiment, after time t2, that is, after the bottom flushing of the second accommodating space 83 is completed, the control component can control the drive component 76 to drive the control mechanism 73 and the water distribution valve core 333 to rotate in the opposite direction of the first direction 91, so that the baffle 334 on the water distribution valve core 333 blocks the second water outlet 332 and makes the first water outlet 331 open. The water flow in the water distribution valve 33 can replenish the second accommodating space 83 through the second water outlet, the first water outlet pipe 42 and the first nozzle 84. When replenishing the second accommodating space 83, the control component can turn off the water pump 50 to stop drawing water from the water tank 10.

[0095] S14: After time t3, the drive component 76 of the control water distribution valve 33 is used to make the water valve assembly 30 in the state of the first water inlet valve 31 closed and the second water inlet valve 32 open, so as to replenish water to the water tank 10 through the water inlet pipe 40 and the second water inlet valve 32.

[0096] In an optional embodiment, after time t3, that is, after the second accommodating space 83 is replenished with water, the control component continues to control the drive component 76 to drive the water distribution valve core 333 and the control mechanism 73 to rotate in the opposite direction of the first direction 91 until the water distribution valve core 333 returns to the initial position, that is, the same side of the first water outlet 331 and the second water outlet 332, without blocking the first water outlet 331 and the second water outlet 332. When the drive unit 76 drives the control mechanism 73 to rotate in the opposite direction of the first direction 91, the locking part 732 on the switching disk 731 disengages from the hook 211 on the float 21, thereby causing the float 21 to descend under its own weight, so as to drive the end of the linkage mechanism 60 with the first column 62 to descend. The first column 62 slides in the limiting groove 212 of the float 21, thereby causing the linkage mechanism 60 with the second column 63 to rotate along the rotating seat 322, thereby causing the linkage mechanism 60 to rotate along the second direction 92 on the rotating seat 322, so that the sealing gasket 61 on the linkage mechanism 60 moves away from the second pilot hole 323, thereby making the second water inlet valve 32 open. Simultaneously, the driving component 76 drives the control mechanism 73 to rotate in the opposite direction of the first direction 91. Under the action of the elastic component 722, the locking component 724 on the piston rod 721 disengages from the switching disc 731. Under the action of the elastic component 722, the piston rod 721 moves towards the first pilot hole 312, causing the rubber component 723 on the piston rod 721 to abut against the first pilot hole 312. At this time, the first water inlet valve 31 closes, and the second water inlet valve 32 opens. Water in the water inlet pipe 40 can replenish water to the water tank 10 through the second water inlet valve 32 and the water supply pipe 41.

[0097] S15: After time t4, the water level in water tank 10 reaches the preset position, the second inlet valve 32 closes, and water replenishment to water tank 10 stops.

[0098] In this embodiment, after time t4, the water level in the water tank 10 reaches the preset position, that is, the water tank 10 is replenished. Specifically, when replenishing the water tank 10, the float 21 will rise under the buoyancy of the water flow in the water tank 10, thereby driving the end of the linkage mechanism 60 with the first column 62 to rise, thereby causing the end of the linkage mechanism 60 with the second column 63 to rotate along the rotating seat 322, that is, the second column 63 rotates in the rotating seat 322, that is, the end with the sealing gasket 61 rotates in the opposite direction of the second direction 92, thereby causing the sealing gasket 61 on the linkage mechanism 60 to abut against the second pilot hole 323, thereby causing the second water inlet valve 32 to close, that is, stopping the water replenishment work of the water tank 10.

[0099] Please see Figure 27 , Figure 27 for Figure 26 A flowchart of an embodiment prior to step S11 is shown. Specifically, the following steps may also be included before step S11:

[0100] S111: The hydraulic pressure value inside the water inlet pipe 40 is obtained through the hydraulic sensor 44.

[0101] In an optional embodiment, when water is supplied to the first inlet valve 31 through the inlet pipe 40, that is, when the second accommodating space 83 needs to be flushed by the water distribution valve 33, the hydraulic sensor 44 in the inlet pipe 40 can obtain the hydraulic value of the tap water and transmit the collected hydraulic value to the control component.

[0102] S112: Compare the hydraulic value with the preset hydraulic value.

[0103] In an optional embodiment, after the control component receives the hydraulic value transmitted by the hydraulic sensor 44, the control component can compare the hydraulic value with a preset hydraulic value to determine whether the water pressure provided by the water flow in the inlet pipe 40 meets the preset requirements when the water valve 33 flushes the second accommodating space 83. Specifically, during side flushing, the flow rate of the side flush water flow must be no less than 14 L / min, preferably 14 L / min-16 L / min; during bottom flushing, the flow rate of the water flow must be no less than 15 L / min. The specific settings can be adjusted according to the volume of the smart toilet, and this application does not impose specific limitations here.

[0104] In this embodiment, during side flushing, the hydraulic sensor 44 detects the hydraulic pressure value in the water inlet pipe 40 and transmits it to the control component. The control component can obtain the flow rate of the incoming water based on the hydraulic pressure value, and can compare the hydraulic pressure value with the preset hydraulic pressure value to determine whether the water pump 50 needs to draw water from the water tank 10 during side flushing.

[0105] S113: If the hydraulic value is less than the preset hydraulic value, the control component controls the water pump 50 to work; if the hydraulic value is not less than the preset hydraulic value, the control component controls the water pump 50 to shut down.

[0106] Furthermore, if the control component determines that the hydraulic pressure is less than a preset hydraulic pressure value, it controls the water pump 50 to operate, thereby increasing the flow rate during side flushing. For example, when the water pressure in the inlet pipe 40 is low, it is necessary to ensure that the water flow, after being sprayed out through the first nozzle 84, can flush the entire inner wall of the second accommodating space 83 during side flushing. When the water pressure is low, the control component controls the water pump 50 to operate, thereby causing the water pump 50 to draw water from the water tank 10 to supply water to the water distribution valve 33, thereby increasing the flow rate of the water during side flushing and ensuring that the water flow can flush the entire inner wall of the second accommodating space 83 during side flushing. Correspondingly, if the hydraulic pressure of the water flow in the inlet pipe 40 is detected to be not less than the preset hydraulic pressure value, it is not necessary to start the water pump 50. The control method for bottom flushing is similar to that for side flushing, and will not be described in detail here.

[0107] 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.
