[0021] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the flushing system provided by the present application.

[0022] The present application provides a flushing system. As shown in Figure 1As shown in the figure, the flushing system of this embodiment includes: a water tank 10, a water pump 20, and a water valve assembly 30. The water tank 10 is communicated with the water pump 20. The water valve assembly 30 includes an inlet valve 31, a separating component 32, and a water distribution valve 33. As Figure 2 shown, the separating component 32 includes an independent first pipe 321 and a second pipe 322. Among them, the first pipe 321 is communicated with the inlet valve 31 and the water distribution valve 33. The water distribution valve 33 is provided with a first water outlet 331 and a second water outlet 332. The water distribution valve 33 selectively conducts the first water outlet 331 or the second water outlet 332. The first water outlet 331 is connected with a first drain pipe 41. The second water outlet 332 is communicated with the water tank 10. The water pump 20 is also communicated with the second pipe 322. The other end of the second pipe 322 is communicated with a second drain pipe 42.

[0023] In some embodiments, one end of the water pump 20 is connected to the water tank 10, and the other end is connected to the second pipe 322 of the separating component 32. The other end of the second pipe 322 is connected to the second drain pipe 42. That is, when it is necessary to pump the water flow in the water tank 10 to perform the corresponding flushing action, the water pump 20 can pump the water flow in the water tank 10 and transmit it to the second drain pipe 42 through the second pipe 322 on the separating component 32, so as to perform the flushing action through the second drain pipe 42.

[0024] Further, the water valve assembly 30 includes an inlet valve 31, a separating component 32, and a water distribution valve 33. Among them, the inlet valve 31 is communicated with the external water flow, and specifically can be communicated with the domestic tap water. When it is necessary for the water distribution valve 33 to perform the corresponding flushing action, the water inlet of the inlet valve 31 can be opened first, so that the water flow enters the interior of the inlet valve 31. Among them, the water outlet of the inlet valve 31 is communicated with the water inlet of the first pipe 321 in the separating component 32, and the water outlet of the first pipe 321 is communicated with the water inlet of the water distribution valve 33. That is, when the water flow enters the inlet valve 31, the water flow in the inlet valve 31 can enter the water distribution valve 33 through the first pipe 321 of the separating component 32. The water distribution valve 33 can selectively reach the first water outlet 331, so that the water flow in the water distribution valve 33 is transmitted to the first drain pipe 41 through the first water outlet 331, so that the first drain pipe 41 performs the corresponding flushing action.

[0025] In some embodiments, the first water outlet 331 and the second water outlet 332 provided on the water distribution valve 33 are selectively conductive. That is, when the first water outlet 331 is conducted, the second water outlet 332 is closed. When the second water outlet 332 is conducted, the first water outlet 331 is closed. That is, when it is necessary for the first drain pipe 41 to perform the flushing action, the first water outlet 331 is in the conductive state and the second water outlet 332 is in the closed state.

[0026] In this embodiment, the second water outlet 332 of the water distribution valve 33 is in communication with the water tank 10. After the water pump 20 pumps the water in the water tank 10 and performs the corresponding drainage action through the second drain pipe 42, the water level in the water tank 10 will correspondingly decrease, that is, the water tank 10 needs to be replenished with water. When replenishing water to the water tank 10, the water inlet of the water inlet valve 31 is in communication, so that water flows into the water inlet valve 31 and is transmitted to the water distribution valve 33 through the first pipe 321. When the water flows into the water distribution valve 33, the water distribution valve 33 selectively communicates with the second water outlet 332 and closes the first water outlet 331, so that the water valve assembly 30 transmits the water flow into the water tank 10, thereby replenishing water to the water tank 10.

[0027] In some embodiments, the operation of the water valve assembly 30 to transmit water flow needs to be achieved by controlling the opening and closing of the water inlet valve 31, that is, when the water valve assembly 30 needs to drain water, it is necessary to control the water inlet valve 31 to be open, and when the water valve assembly 30 does not need to drain water, it is necessary to control the water inlet valve 31 to be closed.

[0028] Therefore, a water distribution valve core (not shown in the figure) is provided in the water distribution valve 33, and the water distribution valve core can move within the water distribution valve 33. An opening and closing assembly (not shown in the figure) is provided in the pilot valve. The pilot valve is connected to the tap water pipeline. The opening and closing assembly can be connected to the water distribution valve core in the water distribution valve 33. When the water distribution valve core rotates within the water distribution valve 33, the water distribution valve core can control the opening and closing of the connection between the pilot valve and the tap water pipeline through the opening and closing assembly, thereby controlling the opening and closing of the water inlet of the pilot valve.

[0029] In an alternative embodiment, a pilot hole (not shown in the figure) is provided on the water inlet valve 31, and the opening and closing of the pilot hole can control the opening and closing of the water inlet of the water inlet valve 31. Specifically, the opening and closing assembly includes a piston rod and a reset member sleeved on the outer side wall of the piston rod. One end of the reset member abuts against the inner side wall of the water inlet valve 31 close to the water distribution valve 33, and the other end abuts against the end of the piston rod away from the water distribution valve 33. A rubber member is provided on the piston rod and is movably connected to the pilot hole. The connection state between the rubber member and the pilot hole can control the opening and closing of the water inlet of the water inlet valve 31. That is, when the water valve assembly 30 does not need to perform the corresponding flushing action, the rubber member on the opening and closing assembly abuts against the pilot hole, so that the water inlet of the water inlet valve 31 is closed. When the water valve assembly 30 needs to perform the corresponding flushing action, the water distribution valve core rotates in the water distribution valve 33, thereby driving the opening and closing assembly away from the pilot hole, that is, driving the rubber member away from the pilot hole through the piston rod, so that the water inlet of the water inlet valve 31 is opened, and tap water enters the water inlet valve 31, so that the water flow can be transmitted to the water tank 10 or the first drain pipe 41 through the isolation member 32 and the water distribution valve 33. When it is necessary to close the water inlet valve 31 when the water valve assembly 30 performs the corresponding flushing action, the water distribution valve core can rotate in the water distribution valve 33, and the piston rod of the opening and closing assembly rebounds under the action of the reset member, so that the rubber member abuts against the pilot hole to close the pilot hole, so that the water inlet of the water inlet valve 31 is closed, and the water valve assembly 30 stops working.

[0030] In this embodiment, the first water outlet 331 and the second water outlet 332 provided on the water distribution valve 33 are selectively communicated, so as to control the water distribution valve 33 to perform different drainage actions. Specifically, a blocking member corresponding to the first water outlet 331 or the second water outlet is further provided on the water distribution valve core, that is, the blocking member can block the first water outlet 331 or the second water outlet respectively. Thus, by rotating the water distribution valve core in the water distribution valve 33, the first water outlet 331 and the second water outlet 332 are blocked, so as to perform the corresponding diversion work through the water distribution valve 33. That is, by providing the blocking member, the water distribution valve 33 has the function of diversion. Among them, a driving member 34 connected to the water distribution valve core is provided on the water distribution valve 33 to drive the water distribution valve core to move.

[0031] In some embodiments, when it is necessary to perform the flushing work through the first drain pipe 41, the water distribution valve core in the water distribution valve 33 rotates so that the blocking member blocks the second water outlet 332. When the water distribution valve core rotates, it drives the opening and closing assembly to disengage from the pilot hole on the water inlet valve 31, so that the water inlet of the water inlet valve 31 is opened, so that the water flow enters the water inlet valve 31, and is transmitted to the water distribution valve 33 through the first pipe 321, and is transmitted to the first drain pipe 41 through the first water outlet 331 on the water distribution valve 33, thus completing the corresponding flushing work.

[0032] Further, when the water tank 10 needs to be replenished with water, the water distribution valve core rotates to block the first water outlet 331 of the water distribution valve 33, so that the second water outlet 332 is conducted. Specifically, it is similar to the above method and will not be elaborated here.

[0033] In this embodiment, since the first drain pipe 41 is connected to the first water outlet 331 of the water distribution valve 33, and the second drain pipe 42 is connected to the water pump 20 through the second pipe 322 of the isolation component 32. That is, when the first drain pipe 41 and the second drain pipe 42 need to flush water simultaneously, the water valve assembly 30 can be controlled to work. Thus, the water valve assembly 30 drains water through the first drain pipe 41, and at the same time, the water pump 20 is controlled to work, so that the water pump 20 can extract the water flow in the water tank 10, transmit it through the second pipe 322 to the second drain pipe 42, and drain water through the second drain pipe 42. That is, the first drain pipe 41 and the second drain pipe 42 can be controlled to drain water simultaneously, effectively improving the versatility and practicality of the flushing system.

[0034] Through the above method, by setting the first drain pipe 41 connected to the water valve assembly 30, and connecting the water pump 20 and the second drain pipe 42 through the second pipe 322 of the isolation component 32, the flushing system can flush water simultaneously through the water pump 20 and the water valve assembly 30, effectively improving the versatility and practicality of the flushing system. Moreover, the water valve assembly 30 is also connected to the water tank 10 and can replenish water to the water tank 10, thereby integrating the flushing system, effectively reducing the volume occupied by the flushing system, and reducing the layout pressure for installing the flushing system.

[0035] In some embodiments, as Figure 3 shown, a water distribution component 50 is provided on the first drain pipe 41. The water distribution component 50 is arranged at the top of the water tank 10. The first end and the second end of the water distribution component 50 are connected to the first drain pipe 41, and the third end is connected to the water tank 10. Wherein, a one-way valve 51 connected to the third end of the water distribution component 50 is arranged in the water tank 10. The first end and the second end of the water distribution component 50 are connected to the first drain pipe 41, that is, the water distribution component 50 is arranged on the first drain pipe 41. For example, the first drain pipe 41 can be cut into two sections, and the two cut sections of the first drain pipe 41 are connected through the water distribution component 50. Among them, the water distribution component 50 is a three-way pipe, that is, the water distribution component 50 includes three interfaces. The first interface is connected to the first water outlet 331 through the first drain pipe 41, the second interface is for draining water, and the third interface is connected to the top of the water tank 10. When the flushing system flushes water through the first drain pipe 41, the water flow in the first drain pipe 41 can be transmitted into the water distribution component 50 through the first end of the water distribution component 50 and discharged through the second end of the water distribution component 50, thereby completing the corresponding flushing work.

[0036] In this embodiment, the third end of the water distribution assembly 50 is connected to the water tank 10, and a one-way valve 51 communicating with the third end of the water distribution assembly 50 is arranged inside the water tank 10. Among them, the water flow direction of the one-way valve 51 is from the water tank 10 to the water distribution assembly 50, that is, the water flow in the water tank 10 can be transmitted to the water distribution assembly 50 through the one-way valve 51 and discharged through the second end of the water distribution assembly 50. That is, when the water flow in the water tank 10 is excessive, the water flow in the water tank 10 can overflow to the water distribution assembly 50 through the one-way valve 51 and be discharged through the water distribution assembly 50, thus effectively avoiding the problem that the water flow in the water tank 10 exceeds the preset liquid level. Since a one-way valve 51 is connected to the third end of the water distribution assembly 50, when the water valve assembly 30 drains water through the first drain pipe 41, the water flow in the flushing assembly can only be transmitted from the first end of the water distribution assembly 50 to the second end and cannot be transmitted from the third end of the water distribution assembly 50 into the water tank 10.

[0037] Among them, when replenishing water to the water tank 10, if the water level in the water tank 10 exceeds the preset water level, that is, after the water flow in the water tank 10 is filled up, if water continues to be replenished to the water tank 10, the water flow exceeding the preset water level can be transmitted to the water distribution assembly 50 through the one-way valve 51 and discharged through the second end of the water distribution assembly 50, thus preventing the water flow in the water tank 10 from exceeding the preset water level.

[0038] In an alternative embodiment, as Figure 4 shown, the water tank 10 includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are detachably connected. Combining Figure 5 with Figure 6 shown, a liquid level detection component 52 located inside the water tank 10 is arranged on the first housing 11. Among them, the first housing 11 and the second housing 12 can be fixed by a snap connection method or can also be fixed by a welding method, and the present application does not make specific limitations here. When the first housing 11 is fixed on the second housing 12, a liquid level detection component 52 located inside the water tank 10 can be arranged on the first housing 11 to detect the water level in the water tank 10. That is, when the water level in the water tank 10 is lower than the preset water level, a signal can be sent to enable the water valve assembly 30 to replenish water to the water tank 10. When the water level in the water tank 10 reaches the preset water level, the liquid level detection component 52 obtains a signal that the water level in the water tank 10 reaches the preset water level and can send a signal to make the water valve assembly 30 stop replenishing water to the water tank 10.

[0039] Among them, the liquid level detection component 52 can specifically be a water float. After the water float abuts against the top of the inner side wall of the first housing 11, a signal that the water level in the water tank 10 reaches the preset water level and that the water tank 10 is full of water is obtained. If the water float does not abut against the top of the inner side wall of the first housing 11, a signal that the water tank 10 is short of water is obtained.

[0040] In some embodiments, when the liquid level detection component 52 fails, that is, when replenishing water to the water tank 10, since the signal of the water level in the water tank 10 cannot be received, the water valve component 30 will continuously replenish water to the water tank 10. The water flow in the water tank 10 exceeding the preset water level can be transmitted to the water distribution component 50 through the one-way valve 51 and discharged through the water distribution component 50.

[0041] In this embodiment, the preset time required for the water tank 10 to complete water replenishment can be obtained. When replenishing water to the water tank 10, if the preset time is exceeded, the water valve component 30 can be controlled to stop replenishing water to the water tank 10, and a signal that the liquid level detection component 52 is damaged can be obtained, and a warning can be issued.

[0042] In an alternative embodiment, when the water valve component 30 and the water pump 20 work in the flushing system, the water flow needs to pass through the isolation component 32, that is, the first pipeline 321 and the second pipeline 322 are arranged on the isolation component 32. Since the first pipeline 321 and the second pipeline 322 are independently arranged, that is, the first pipeline 321 and the second pipeline 322 are not communicated with each other, when the water valve component 30 and the water pump 20 perform the flushing operation, the flow path of the water flow is independent. And since when the flushing system is flushing, if the water flow in the water valve component 30 and the water pump 20 is discharged, phenomena such as siphon may occur. Therefore, a first isolation valve core and a second isolation valve core are arranged in the isolation component 32, and the first isolation valve core and the second isolation valve core are respectively arranged in the mutually independent first pipeline 321 and second pipeline 322. Among them, the states of the first pipeline 321 and the second pipeline 322 being communicated or not communicated with the outside are respectively controlled by the first isolation valve core and the second isolation valve core.

[0043] In this embodiment, when supplying water to the water distribution valve 33, there is water flow in the first pipeline 321. Under the action of the water flow, a certain buoyancy will be generated on the first isolation valve core, so that the first isolation valve core blocks the channel for the first pipeline 321 to communicate with the outside, so that the first pipeline 321, that is, the inside of the water valve component 30, is isolated from the outside. After the isolation component 32 transmits the water flow into the water distribution valve 33, since there is no water in the first pipeline 321 of the isolation component 32, at this time, the first isolation valve core will fall under the action of its own gravity, so that the first pipeline 321 communicates with the outside, and the outside air can enter the water valve component 30 through the isolation component 32, making the internal and external air pressures of the water valve component 30 the same, so as to avoid the occurrence of siphon phenomena. And when the water flow of the water pump 20 is transmitted to the second drain pipe 42 through the second pipeline 322, the working state of the second isolation valve core is the same as that of the above-mentioned first isolation valve core, and will not be elaborated here too much. That is, the second isolation valve core can be used to avoid the occurrence of siphon phenomena after the water pump 20 finishes flushing.

[0044] In some embodiments, the flushing system further includes a control component (not shown in the figure), which is coupled to the water valve component 30, the water pump 20, and the liquid level detection component 52 to control the working states of the water valve component 30 and the water pump 20 and receive the liquid level signal fed back by the liquid level detection component 52. That is, when using the flushing system, the working states of the water valve component 30 and the water pump 20 can be controlled through the control component, thereby completing the corresponding flushing work. And the control component can receive the signal transmitted by the liquid level detection component 52 to determine whether the water in the water tank 10 is lacking. If the water is lacking, the control component controls the water valve component 30 to replenish water for the water tank 10. If the water tank 10 is full of water, the control component controls the water valve component 30 to stop replenishing water for the water tank 10. In this embodiment, the control component can also be connected to the driving member 34, so as to control the movement state of the water distribution valve core in the water distribution valve 33 by controlling the working state of the driving member 34.

[0045] The present application also provides an intelligent toilet, as Figure 7 shown, which includes the flushing system and the housing 60 of any of the above embodiments. An inner wall 61 is provided inside the housing 60 to form a first accommodation space 62 and a second accommodation space 63 inside the housing 60, and the flushing system is arranged in the first accommodation space 62. Combining Figure 1 shown, a first spray head 64 and a second spray head 65 are provided on the inner wall 61. The first spray head 64 is arranged on the side wall of the inner wall 61 and is communicated with the first drain pipe 41, and the second spray head 65 is arranged at the bottom of the inner wall 61 and is communicated with the second drain pipe 42.

[0046] In this embodiment, combining Figure 8 with Figure 9 shown, an inner wall 61 is formed inside the housing 60, thereby dividing the inside of the housing 60 into two accommodation spaces, that is, the first accommodation space 62 and the second accommodation space 63. Among them, the first accommodation space 62 is used to install external devices, for example, the water valve component 30 and the water pump 20, etc. The second accommodation space 63 is a sewage pool, and both the first drain pipe 41 and the second drain pipe 42 are communicated with the second accommodation space 63, thereby completing the cleaning work of the second accommodation space 63. Among them, the first drain pipe 41 and the second drain pipe 42 are connected to different positions of the second accommodation space 63, that is, at different positions of the inner wall 61, so that when the water valve component 30 and the water pump 20 are working, different cleaning tasks of the second accommodation space 63 are completed. Specifically, a first spray head 64 communicated with the first drain pipe 41 and a second spray head 65 communicated with the second drain pipe 42 are provided on the inner wall 61, so that when draining water through the first drain pipe 41 and the second drain pipe 42, the second accommodation space 63 can be cleaned through the first spray head 64 and the second spray head 65. Among them, the first spray head 64 is a side spray head, and the second spray head 65 is a bottom spray head, that is, the second accommodation space 63 can be side-sprayed through the first spray head 64, and the second accommodation space 63 can be bottom-sprayed through the second spray head 65.

[0047] In this embodiment, as Figure 10 shown, when cleaning the second accommodation space 63, the flow path of the water is as follows: When cleaning the second accommodation space 63 through the water valve assembly 30, the transmission path of the water flow is: The water enters the inlet valve 31 and is transmitted to the isolation component 32 through the first pipeline 321. After entering the isolation component 32, it is transmitted to the water distribution valve 33 through the first pipeline 321. After entering the water distribution valve 33, it is transmitted to the first drain pipe 41 through the first water outlet 331 on the water distribution valve 33, and is transmitted to the second accommodation space 63 through the first spray head 64 connected to the first drain pipe 41, so as to clean the second accommodation space 63 through the water valve assembly 30. When cleaning the second accommodation space 63 through the water pump 20, the transmission path of the water flow is: The water pump 20 extracts the water flow in the water tank 10 and transmits it to the isolation component 32 through the second pipeline 322. After entering the isolation component 32, it is transmitted to the second drain pipe 42 through the second pipeline 322, and is transmitted to the second accommodation space 63 through the second spray head 65 connected to the second drain pipe 42, so as to clean the second accommodation space 63 through the water pump 20.

[0048] In some embodiments, a side flushing port and a bottom flushing port are provided in the second accommodation space 63 of the intelligent toilet. The first spray head 64 is arranged in the side flushing port, and the second spray head 65 is arranged in the bottom flushing port. When the water valve assembly 30 cleans the second accommodation space 63 through the first spray head 64 connected to the first drain pipe 41, the water flow in the water tank 10 can be extracted by the water pump 20 to clean the second accommodation space 63 at the same time, that is, the second accommodation space 63 can be flushed from the side and the bottom at the same time. Since the noise generated is relatively large when flushing the sewage pool of the intelligent toilet alone from the bottom, the sewage pool can also be flushed from the side through the water valve assembly 30 when flushing the sewage pool from the bottom. The side flushing can effectively reduce the noise generated during the bottom flushing, that is, when flushing the second accommodation space 63 from the bottom and the side at the same time, the noise during the cleaning of the second accommodation space 63 can be effectively reduced.

[0049] In other embodiments, the second accommodation space 63 can be flushed from the side first, and then from the bottom, or the second accommodation space 63 can be flushed from the bottom first, and then from the side. Specifically, it can be set according to actual needs, and the present application does not make specific limitations here.

[0050] In some embodiments, the distance between the second nozzle 65 and the bottom of the inner wall 61 is less than the distance between the isolation component 32 and the bottom of the inner wall 61. That is, the distance between the isolation component 32 and the liquid level in the second accommodating space 63 needs to be greater than the distance between the second nozzle 65 and the liquid level in the second accommodating space 63. Preventing the water flow in the water tank 10 from being sucked into the second accommodating space 63 by siphoning, avoiding the situation where the liquid level in the water tank 10 decreases, and thus requiring continuous water replenishment for the water tank 10. Specifically, the distance between the isolation component 32 and the second nozzle 65 in the vertical direction can be 25 cm, or any other distance that can prevent the water flow in the water tank 10 from being sucked into the second accommodating space 63 by siphoning, such as 30 cm. The specific setting can be based on demand, and this application does not make specific limitations here.

[0051] In some embodiments, the water pump 20 is arranged at the bottom end of the outer shell 60, and the water tank 10 is snapped onto the inner wall of the outer shell 60, that is, the water pump 20 and the water tank 10 are arranged in the first accommodating space 62. The water pump 20 is arranged at the bottom end of the outer shell 60 and can be arranged close to the water tank 10, which can effectively integrate the devices in the smart toilet, thereby reducing the volume occupied by the smart toilet.

[0052] In other embodiments, another three-way pipe can be provided on the second drain pipe 42, one end of which is connected to the second pipe 322 of the isolation component 32, and the other end is respectively connected to two bottom flushing nozzles, so as to bottom flush the second accommodating space 63. Specifically, it can be set according to actual needs, and the present application does not limit it here.

[0053] In a specific application scenario, when the smart toilet needs to be side-flushed, the control component can control the driving component 34 to work so as to control the water diversion valve core to rotate in the water diversion valve 33. The water diversion valve core rotates to drive the opening and closing component away from the pilot hole, so that the water inlet of the water inlet valve 31 is opened, so as to transmit the water flow to the water diversion valve 33 through the isolation component 32, and when the water diversion valve core rotates in the water diversion valve 33, the sealing member on the water diversion valve core can block the second water outlet 332, and the first water outlet 331 is opened, and the water flow can be transmitted to the first drain pipe 41 through the first water outlet 331, and the second accommodating space 63 is side-flushed through the first nozzle 64. After the side flush is completed, the water diversion valve core can be controlled to rotate so that the water diversion valve core rotates to the initial position, that is, the first water outlet 331 and the second water outlet 332 are not blocked. At this time, the piston rod of the opening and closing assembly can make the rubber part on the piston rod abut against the pilot hole under the action of the reset part, so that the water inlet of the water inlet valve 31 is closed, and the water valve assembly 30 is closed.

[0054] Furthermore, when the smart toilet needs to be bottom-flushed, the control component can control the water pump 20 to extract the water flow in the water tank 10, and transmit it to the second drain pipe 42 through the second pipe 322 of the isolation component 32, and bottom-flush the second accommodating space 63 through the second nozzle 65 connected to the second drain pipe 42. After the bottom flush, the liquid level in the water tank 10 decreases, and the liquid level detection component 52 can transmit a signal to the control component, and the control component can control the water valve component 30 to replenish water for the water tank 10. The specific water replenishment work is similar to the side flushing mentioned above, and will not be described in detail here. The difference is that the blocking member of the water diversion valve core blocks the first water outlet 331, and the second water outlet 332 is connected. After the water replenishment is completed, the liquid level detection component 52 detects that the liquid level of the water tank 10 reaches the preset liquid level, and at this time transmits a signal to the control component, and the control component controls the water valve component 30 to stop working.

[0055] The present application also provides a flushing direction, and the flushing method is applied to a smart toilet as in any of the above-mentioned embodiments.

[0056] See also Figure 11 and Figure 15 , Figure 11 is a flow chart of the first embodiment of the control method of the flushing system of the present application, Figure 15 1 is a schematic diagram of the structure of the first embodiment of the control method of the flushing system of the present application. It should be noted that if there is substantially the same result, the method of the present invention is not limited to Figure 11 The process sequence shown is limited. Figure 11 As shown, the method comprises the following steps: S11: the control component controls the water valve component 30 to operate, and flushes the second accommodating space 63 through the first nozzle 64 .

[0057] Specifically, the control component controls the operation of the driving component 34, so that the driving component 34 drives the water diversion valve core to rotate along the first direction in the water diversion valve 33, so that the sealing component on the water diversion valve core blocks the second water outlet 332, and when the water diversion valve core rotates, it synchronously drives the opening and closing component away from the pilot hole of the water inlet valve 31, so that the water inlet valve 31 opens. After the water inlet valve 31 is opened, the water flow is transmitted to the water diversion valve 33 through the isolation component 32, and is transmitted to the first drain pipe 41 through the first water outlet 331 of the water diversion valve 33, and the second accommodating space 63 of the smart toilet is cleaned through the first nozzle 64 connected to the first drain pipe 41, that is, the sewage tank is side-flushed.

[0058] S12: After time t1 has passed, the control component controls the water pump 20 to operate, and flushes the second accommodating space 63 with water through the second nozzle 65 .

[0059] Specifically, after a time t1, that is, after a time t1 of performing side flushing on the second accommodation space 63, the control component transmits an instruction to the water pump 20, and the water pump 20 starts to work. The water pump 20 pumps the water in the water tank 10 and transmits it through the second pipeline 322 of the isolation component 32 to the second drain pipe 42, and flushes the second accommodation space 63 through the second spray head 65 connected to the second drain pipe 42, that is, performs bottom flushing on the sewage discharge pool.

[0060] In this embodiment, when performing bottom flushing on the second accommodation space 63, side flushing is carried out synchronously, that is, bottom flushing and side flushing are carried out simultaneously.

[0061] S13: After a time t2, the control component controls the water pump 20 to stop working.

[0062] Specifically, after the bottom flushing and side flushing of the intelligent toilet are completed, that is, after flushing the second accommodation space 63 for a period of time, the control component sends an instruction to the water pump 20, and the water pump 20 stops working, while side flushing continues to replenish water to the second accommodation space 63. That is, after simultaneously performing bottom flushing and side flushing on the second accommodation space 63, the water flow in the second accommodation space 63 is completely discharged, and at this time, the second accommodation space 63 is in a waterless state. At this time, it is necessary to replenish water to the second accommodation space 63 through side flushing to play a role in isolating odors.

[0063] S14: After a time t3, the control component controls the water valve assembly 30 to stop flushing the second accommodation space 63 and controls the water valve assembly 30 to replenish water to the water tank 10.

[0064] In this embodiment, after a time t3, that is, when the water replenishment in the second accommodation space 63 is completed at this time, the control component sends an instruction to the driving member 34, and the driving member 34 drives the water distribution valve core to rotate in the second direction (wherein, the first direction and the second direction are two opposite directions. For example, when the first direction is the clockwise direction, the second direction is the counterclockwise direction). The water distribution valve core drives the blocking member on the water distribution valve core to disengage from the second water outlet 332. At this time, the water distribution valve core is in the initial state, and the opening and closing assembly blocks the pilot hole of the inlet valve 31 under the action of the reset member, so that the inlet valve 31 is closed. After the inlet valve 31 is closed, the driving member 34 continues to drive the water distribution valve core to rotate in the second direction, so that the blocking member on the water distribution valve core blocks the first water outlet 331, and drives the opening and closing assembly away from the pilot hole, so that the pilot hole is opened to open the inlet valve 31. At this time, the water flows through the water valve assembly 30 and starts to replenish water to the water tank 10 through the second water outlet 332.

[0065] Please refer to Figure 12 and Figure 16 , Figure 12 is a schematic flow chart of the second embodiment of the control method of the flushing system of the present application.

Figure 12 As shown, the method comprises the following steps: S21: The control component controls the water valve component 30 to operate, and flushes the second accommodating space 63 through the first nozzle 64 .

[0066] In the embodiment, the control component controls the water valve component 30 to start side flushing, that is, the driving component 34 controls the water diversion valve core to rotate in the first direction and blocks the second water outlet 332, which is the same as the above-mentioned step S11 and will not be elaborated here.

[0067] S22: After time t1 has passed, the control component controls the water pump 20 to work, and controls the water valve component 30 to replenish water for the water tank 10 .

[0068] In this embodiment, after time t1, the control component sends a command to the water pump 20, and the water pump 20 starts to work. The water pump 20 extracts water from the water tank 10 and transmits it to the second nozzle 65 through the isolation component 32 and the second drain pipe 42 to perform bottom flushing on the second accommodating space 63. While bottom flushing, the control component sends a command to the driving member 34, so that the driving member 34 controls the water diversion valve core to rotate in the second direction until the blocking member of the water diversion valve core blocks the first water outlet 331, and the water flow in the water valve assembly 30 starts to replenish water for the water tank 10. At this time, the water tank 10 replenishes water and the water pump 20 performs bottom flushing on the second accommodating space 63 simultaneously.

[0069] S23: After time t2 has passed, the control component controls the water pump 20 to stop working, and controls the water valve component 30 to flush the second accommodating space 63 with water.

[0070] Specifically, after time t2, the control component sends a command to the water pump 20, the water pump 20 stops working, and sends a command to the driving member 34, the driving member 34 controls the water diversion valve core to rotate in the first direction, the blocking member of the water diversion valve core rotates to the initial position, that is, the blocking member is located between the first water outlet 331 and the second water outlet 332, at this time, the opening and closing assembly blocks the pilot hole under the action of the reset member, and the water inlet valve 31 is closed. When the water diversion valve core is in the initial state, the control component continues to control the driving member 34 to work, so that the driving member 34 continues to drive the water diversion valve core to rotate in the first direction until the blocking member on the water diversion valve core completely blocks the second water outlet 332, and the water diversion valve core rotates and synchronously drives the opening and closing assembly to disengage from the pilot hole, at this time, the water inlet valve 31 and the first water outlet 331 of the water diversion valve 33 are in the open state, and the water flow in the water valve assembly 30 starts to replenish the second accommodating space 63 through the first water outlet 331, the first drain pipe 41 and the water diversion assembly 50.

[0071] S24: After a time t3, the control component controls the water valve component 30 to stop flushing the second accommodation space 63, and controls the water valve component 30 to replenish water to the water tank 10.

[0072] Specifically, this step is the same as the above S14 step, and will not be elaborated here.

[0073] Please refer to Figure 13 and Figure 17 , Figure 13 is a schematic flow chart of the third embodiment of the control method of the flushing system of the present application, Figure 17 is a schematic structural diagram of the third embodiment of the control method of the flushing system of the present application. It should be noted that if there are substantially the same results, the method of the present invention is not limited to Figure 13 the flow sequence shown. As Figure 13 shown, the method includes the following steps: S31: The control component controls the water valve component 30 to work, and flushes the second accommodation space 63 through the first nozzle 64.

[0074] Specifically, this step is the same as the above S11 step, and will not be elaborated here.

[0075] S32: After a time t1, the control component controls the water pump 20 to work, and controls the water valve component 30 to stop working.

[0076] In this embodiment, after a time t1, the control component sends an instruction to the water pump 20, so that the water pump 20 performs bottom flushing on the second accommodation space 63. During bottom flushing, the control component sends an instruction to the driving member 34, and the driving member 34 controls the water distribution valve core to rotate in the second direction until the blocking member on the water distribution valve core is located between the first water outlet 331 and the second water outlet 332, and the opening and closing component blocks the pilot hole, so that the inlet valve 31 is closed, that is, the water valve component 30 is closed.

[0077] S33: After a time t2, the control component controls the water pump 20 to stop working, and controls the water valve component 30 to flush the second accommodation space 63.

[0078] In this embodiment, after a time t2, the control component sends to the water pump 20, the water pump 20 stops working, and sends an instruction to the driving member 34. The driving member 34 drives the water distribution valve core to rotate in the first direction until the blocking member on the water distribution valve core blocks the second water outlet 332. At this time, the water valve component 30 starts to replenish water to the second accommodation space 63 through the first water outlet 331.

[0079] S34: After a time t3, the control component controls the water valve component 30 to stop flushing the second accommodation space 63, and controls the water valve component 30 to replenish water to the water tank 10.

[0080] Specifically, this step is the same as step S14 above and will not be elaborated here.

[0081] Please refer to Figure 14 , Figure 14 which is Figure 11 a schematic flow diagram of an embodiment after step S14 in . Specifically, after the above step S14, the following steps may further be included: And since the above step S14 is the same as steps S24 and S34, the following steps may further be included after the above steps S24 and S34: S41: After a time t4, the control component obtains the liquid level signal fed back by the liquid level detection component 52 and stops replenishing water to the water tank 10.

[0082] In this embodiment, after a time t4, when the liquid level detection component 52 detects that the water level in the water tank 10 reaches the preset water level, the liquid level detection component 52 feeds back the signal to the control component. After receiving the instruction, the control component controls the driving member 34 to rotate in the first direction. At this time, the blocking member on the water distribution valve core is located between the first water outlet 331 and the second water outlet 332, and the opening and closing component blocks the pilot hole under the action of the reset member, so that the water inlet valve 31 is closed and the flushing process ends.

[0083] S42: After a time t5, the control component does not receive the liquid level signal fed back by the liquid level detection component 52 and stops replenishing water to the water tank 10.

[0084] In this embodiment, if after a time t5, the liquid level detection component 52 does not transmit a signal to the control component, the control component issues an instruction to close the water valve assembly 30 to close the water inlet valve 31, and at the same time issues an alarm for the liquid level detection component 52. At this time, the liquid level detection component 52 may be damaged. Among them, the time t5 needs to be greater than the time for the water tank 10 to complete water replenishment, that is, the time required for the water tank 10 to replenish water from being empty to full, which can be specifically set according to the capacity of the water tank 10 and will not be limited too much in this application.

[0085] The above is only the implementation manner of this application, and does not limit the patent scope of this application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of this application.
