[0011] The technical solution of the present disclosure will be described below by way of embodiments with reference to the drawings. It can be understood that the examples described herein are for illustrating the technical aspects of the present disclosure, but do not limit the technical aspects of the present disclosure.

[0012] Currently, in order to enable a single-channel jet head to function normally under both low and high water pressures, or due to limitations on pump power, it is necessary to reduce the diameter of the jet head nozzle to meet the toilet's waste discharge needs at different water pressures. Simply reducing the diameter of the jet head nozzle results in significant toilet noise at high water pressures. Increasing the diameter of the jet head nozzle results in poor toilet waste discharge efficiency at low water pressures. In such cases, a high-power pump is required to achieve a high waste discharge effect. Using a high-power pump also creates the problem of being unable to operate the pump at full power using backup battery power during a power outage, resulting in poor toilet waste discharge efficiency. The jet head according to the present embodiment can meet various usage scenarios and achieve excellent toilet waste discharge efficiency.

[0013] In one embodiment of the present application, as shown in FIGS. 1 to 21, a jet head is provided for use in a toilet to assist in the discharge of waste from the toilet. As shown in FIGS. 2 and 5, the jet head may be attached to the nozzle 101 of the toilet body 1, and the jet head may include the main body 2 and an adapter 3 fitted to the outer wall of the main body 2. The toilet body 1 may be made of a ceramic material, a plastic material, or the like. The main body portion of the main body 2 may be a hollow cylinder with a constant diameter, a hollow cylinder with a variable cross-section, or a hollow truncated cone. As shown in FIGS. 11 and 12, for example, the main body portion of the main body 2 may be a hollow cylinder. The adapter 3 is rotatable around a central axis along the length of the main body 2. For example, the state after the adapter 3 is fitted into the main body 2 is shown in FIGS. 3 and 6. The main body 2 may be made of a material such as metal or plastic.

[0014] As shown in Figure 2, the main body 2 is provided with a first water passage 201, a second water passage 202, a first water inlet 201a and a first water outlet 201b communicating with the first water passage 201, and a second water inlet 202a and a second water outlet 202b communicating with the second water passage 202. As shown in Figures 1 and 4, the first water outlet and the second water outlet may both be arranged toward the water inlet of a siphon bend in the toilet so that good flushing effects can be obtained in either the first water passage 201 or the second water passage 202. The flow areas of the first water outlet 201b and the second water outlet 202b are different.

[0015] As shown in Figure 2, the adapter 3 is provided with a flow path 301 and an inlet 301a and outlet 301b communicating with the flow path 301. The inlet 301a may be circular or have any other shape and is used to connect to a water pipe to supply water to the jet head. The adapter 3 may communicate with either the first water path 201 or the second water path 202. In the embodiments of the present application, the technical solution will be described using the adapter 3 communicating with the first water path 201 as an example. As shown in Figure 2, the outlet 301b of the adapter 3 communicates with the first water inlet 201a.

[0016] The jet head according to the embodiment of the present application has two water channels, a first water channel and a second water channel, and the outlets of the two water channels have different flow areas, allowing the toilet to be adapted to various usage scenarios. For example, when the water supply pressure is high, the water channel with the larger outlet flow area can be selected to supply water, effectively reducing flushing noise and achieving a superior flushing effect. When the water supply pressure is low, the water channel with the smaller outlet flow area can be selected to supply water, achieving a superior flushing effect, while still achieving essentially the same flushing effect under different water supply pressures. Alternatively, selecting two water channels to supply water synchronously can meet different user needs. Furthermore, the relative adjustability of the adapter 3 and the main body 2 allows the inlet 301a to be adjustable, improving the flexibility of the jet head to accommodate different toilet configurations and improving the practicality of the jet head. In actual use, a water source is connected to the second water inlet 202a and the inlet 301a of the jet head to supply water to the toilet.

[0017] In some exemplary embodiments, as shown in FIGS. 2 and 5 , the jet head may further include a water flow groove 4. The water flow groove 4 is located between the adapter 3 and the main body 2. The outlet 301b of the adapter 3 can be connected to the first water inlet 201a through the water flow groove 4. As shown in FIGS. 2 and 5 , the water may enter the flow path 301 from the inlet 301a, enter the water flow groove 4 via the outlet 301b, then flow into the first water inlet 201a, and be ejected from the first water outlet 201b via the first water passage 201. As shown in FIGS. 2 and 5 , the water flow groove 4 may be disposed around the circumferential direction of the main body 2. Depending on the design of the rotation angle range of the adapter 3 relative to the main body 2 in actual applications, the water flow groove 4 may be disposed around half the circumferential direction of the main body 2, or the water flow groove 4 may be disposed around one circumferential direction of the main body 2.

[0018] In some exemplary embodiments, as shown in FIG. 2 , an annular groove may be provided in one of the adapter 3 and the main body 2, and the annular groove may surround the other of the adapter 3 and the main body 2 to form the annular water passage groove 4. For example, an annular groove may be provided in the inner wall of the adapter 3, and the annular groove may surround the outer wall of the main body 2 to form the annular water passage groove 4. Alternatively, an annular groove may be provided in the outer wall of the main body 2, and the annular groove may surround the inner wall of the adapter 3 to form the annular water passage groove 4. Alternatively, annular grooves may be provided in the outer wall of the main body 2 and the inner wall of the adapter 3, and the two annular grooves may together surround the annular water passage groove 4. Exemplarily, the water passage groove 4 may be annular. As shown in FIG. 2 , the water passage groove 4 may extend circumferentially around the main body 2, and the depth of the water passage groove 4 may be set to a constant value, or the depth of the water passage groove 4 may be a dimension along the radial direction of the water passage groove 4. Alternatively, as shown in FIG. 5 , the water passage groove 4 may extend circumferentially around the main body 2, and the depth of the water passage groove 4 may gradually increase.

[0019] 2, the outlet 301b may be located in the middle of the water channel 4 along the axial direction of the main body 2, i.e., along the left-right direction, and the outlet 301b is not located at the end of the water channel 4 along the axial direction of the main body 2. This reduces the assembly accuracy requirements for the adapter 3 and the main body 2, reduces the structural accuracy requirements for the limiting structure, etc., and reduces assembly costs, while making it easier to arrange a sealing structure between the adapter 3 and the main body 2 and improving the sealing performance of the entire jet head.

[0020] 17 and 18, the adapter 3 may include an annular socket portion 302 and a hollow cylindrical extension portion 303, the extension portion 303 extending in a direction away from the socket portion 302, and the socket portion 302 communicating with the extension portion 303. The socket portion 302 and the extension portion 303 may be manufactured by integral molding, for example, by casting or injection molding, etc.

[0021] As shown in Figure 6, the scape portion 302 may be fitted into the outer wall of the main body 2, and the extension portion 303 may extend radially of the main body 2 in a direction away from the central axis along the length of the main body 2. The angle formed between the central axis of the extension portion 303 along its own length and the central axis of the socket portion 302 along its own length is defined as α, and α may be an acute angle or an obtuse angle. The inlet 301a may be provided at one end of the extension portion 303 that is away from the main body 2. The through opening where the extension portion 303 communicates with the socket portion 302 is the outlet 301b.

[0022] In some exemplary embodiments, as shown in Figures 17 and 18, the outer wall of the socket portion 302 may be designed with differentiation. For example, some areas of the outer wall of the socket portion 302 may be designed to be thin, thereby reducing the overall weight of the jet head and the manufacturing costs of the product.

[0023] In some exemplary embodiments, as shown in FIGS. 2 and 5, at least a portion of the bottom of the water flow groove 4 may be inclined to form a guide wall 401. For example, the entire bottom of the water flow groove 4 may be inclined, or a localized area of ​​the bottom of the water flow groove 4 near the first water inlet 201a may be inclined. The guide wall 401 can guide the injected water toward the first water outlet 201b. The guide wall 401 allows the injected water from the water flow groove 4 to smoothly flow into the first water passage 201, and also allows the injected water from the second water inlet 202a to smoothly flow into the second water passage 202, thereby achieving good cleaning performance for the entire injected water.

[0024] In some exemplary embodiments, as shown in Figures 2 and 5, the guide surface of the guide wall 401 may be an oblique surface, or may be an arc-shaped surface, etc., to meet the flow area requirements of different water channels and improve the fluid flow performance.

[0025] 2 and 5, a passage is provided in the main body 2, and a partition rib 203 is provided in the passage. The partition rib 203 is used to divide the passage into a first water passage 201 and a second water passage 202.

[0026] In some exemplary embodiments, as shown in FIG. 13, the partition rib may include a first segment 203a and a second segment 203b that are smoothly adjacent to each other. Alternatively, as shown in FIG. 14, the partition rib may include a first segment 203a, a second segment 203b, and a third segment 203c that are smoothly adjacent to each other. For example, the first segment 203a, the second segment 203b, and the third segment 203c may be arranged sequentially along the length of the main body 2, with the first segment 203a being closer to the first water outlet 201b than the second segment 203b and the third segment 203c. As shown in FIGS. 13 and 14, the partition rib and the water channel 4 may share a common portion, simplifying the internal design of the jet head and reducing the overall weight of the product. For example, the second segment 203b of the partition rib may serve as a flow guide wall 401.

[0027] In some exemplary embodiments, as shown in FIGS. 2 and 5 , the flow area of ​​the first water passage 201 may be designed to be a constant value, and the flow area of ​​the first water passage 201 may be the same as the flow area of ​​the first water outlet 201b, and the shape of the first water passage 201 in a plane perpendicular to its own length may be the same as the shape of the first water outlet 201b. Alternatively, the flow area of ​​the first water passage 201 may be designed to be a non-constant value in the length direction along the first water passage 201, and the flow area of ​​the region of the first water passage 201 close to the first water outlet 201b may be the same as the flow area of ​​the first water outlet 201b. Alternatively, the flow area of ​​the first water passage 201 may gradually decrease toward the first water outlet 201b. Alternatively, the flow area of ​​the first water passage 201 may gradually increase toward the first water outlet 201b. By designing the flow area of ​​the first water passage 201 with reference to the flow area of ​​the first water outlet 201b, it is possible to avoid a sudden change in the flow area at the connection point between the first water passage 201 and the first water outlet 201b, reduce energy loss during the flow process of the spray water, and obtain a good cleaning effect. The flow area of ​​the second water passage 202 may be designed with reference to the flow area of ​​the first water passage 201. For example, the flow area of ​​the second water passage 202 may be designed to be the same as the flow area of ​​the second water outlet 202b, or the flow area of ​​a region of the second water passage 202 close to the second water outlet 202b may be designed to be the same as the flow area of ​​the second water outlet 202b.

[0028] In some exemplary embodiments, as shown in Fig. 5, multiple seal rings 5 ​​may be provided between the adapter 3 and the main body 2. As shown in Fig. 21, the structure of the seal rings 5 ​​may be such that multiple seal rings 5 ​​are installed on both sides of the outlet 301b along the length of the main body 2 itself, thereby realizing a seal in the mating area between the adapter 3 and the main body 2, improving the sealing performance of the jet head, and preventing leakage. For example, the seal rings 5 ​​may be oil seals or the like.

[0029] In some exemplary embodiments, as shown in Figures 13 and 14, the seal groove 204 may be provided in one of the adapter 3 and the main body 2, and Figures 13 and 14 show that the seal groove 204 is provided in the main body 2. As shown in Figure 5, the seal ring 5 is fitted into the seal groove 204, and the seal ring 5 is contact-fitted to the adapter 3. In the embodiments of the present application, the technical solution will be described by taking the seal groove 204 provided in the main body 2 as an example. As shown in Figure 5, the seal ring 5 may be pressed into the seal groove 204 or glued into the seal groove 204. During the assembly process of the jet head, the adapter 3 may be installed after the seal ring 5 is installed in the seal groove 204 of the main body 2.

[0030] In some exemplary embodiments, as shown in FIGS. 5 and 6, the jet head may further include a limiting plate 205 and a fixing nut 206. The structure of the fixing nut 206 is shown in FIG. 19. The limiting plate 205 may be annular and fixed to one end of the main body 2. For example, the limiting plate 205 may be fitted into the outer wall of the main body 2 and fixed thereto. For example, the limiting plate 205 and the main body 2 may be integrally molded by injection molding or the like. Alternatively, the limiting plate 205 and the main body 2 may be molded separately and then welded. Alternatively, the limiting plate 205 and the main body 2 may be molded separately and then fixed with screws or the like. After the jet head is installed, the fixing nut 206 is fitted and fixed to the outer wall of the main body 2 and tightly clamped together with the limiting plate 205 at the nozzle 101 of the toilet main body 1 along the length of the main body 2 to fix the jet head. As shown in FIGS. 2 and 5, the fixing nut 206 and the limiting plate 205 are respectively positioned on both sides of the nozzle 101 of the toilet body 1 in the length direction thereof, and the limiting plate 205 may be positioned within the bowl of the toilet body 1.

[0031] 2 and 5, the jet head may further include a sealing rubber pad 207. The sealing rubber pad 207 may be made of rubber or the like. The sealing rubber pad 207 may be fitted into the outer wall of the main body 2, and the sealing rubber pad 207 may be annular, contact the limiting plate 205, and be pressed between the toilet main body 1 and the limiting plate 205. The structure of the sealing rubber pad 207 is shown in FIG.

[0032] As shown in Figure 5, during the installation process of the jet head, one end of the body 2 away from the limiting plate 205 is inserted into the nozzle 101 from one side of the inside of the bowl of the toilet body 1. The opening dimension of the nozzle 101 is larger than the outer contour dimension of the area of ​​the body 2 where the limiting plate 205 is not installed, ensuring smooth installation of the jet head. The opening dimension of the nozzle 101 is smaller than the outer contour dimension of the limiting plate 205, ensuring secure installation of the jet head into the nozzle 101.

[0033] In some exemplary embodiments, as shown in Fig. 5, the adapter 3 may be tightly clamped between the fixing nut 206 and the nozzle 101 of the toilet body 1. Alternatively, as shown in Fig. 2, the adapter 3 may be installed on the side of the fixing nut 206 away from the limiting plate 205, for example, the adapter 3 may engage with the body 2. This allows the adapter 3 and the body 2 to be detachably assembled, and the rotation angle of the adapter 3 relative to the body 2 can be easily adjusted, improving the flexibility and adaptability of the jet head product adjustment.

[0034] In some exemplary embodiments, as shown in FIG. 2 , an outer wall of the main body 2 may be provided with an avoidance groove 208 that is recessed along the radial direction of the main body 2 and toward the inside of the main body 2. A limiting buckle 209 may further be provided on the outer wall of the main body 2. The limiting buckle 209 is connected to the groove wall of the avoidance groove 208 and is elastically deformable along the radial direction of the main body 2. As shown in FIG. 2 , a limiting portion 210 may be provided on one end of the limiting buckle 209 that is away from the groove wall. The limiting portion 210 may be located on a side closer to the fixing nut 206. At least a portion of the limiting portion 210 may protrude from the outer wall of the main body 2. The limiting portion 210 restricts the adapter 3 from being removed from the main body 2 along the length direction of the main body 2. As shown in FIG. 2 , the limiting portion 210, together with the fixing nut 206, can limit the position of the adapter 3 relative to the main body 2.

[0035] In some exemplary embodiments, as shown in FIGS. 7 to 10 , a limiting groove 211 extending along the circumferential direction of the main body 2 may be provided on the outer wall of the main body 2. The limiting groove 211 may be located close to an end of the main body 2, away from the limiting plate 205. As shown in FIG. 8 , one groove wall of the limiting groove 211 and one groove wall of the sealing groove 204 may be shared, thereby simplifying the design structure of the jet head. As shown in FIG. 8 , the limiting groove 211 does not form a closed ring along the circumferential direction of the main body 2, and the limiting groove 211 may have a notch 212, and the number of notches 212 may be one or more. As shown in FIG. 7 , a limiting protrusion 304 may be provided on the inner wall of the adapter 3. The limiting protrusion 304 fits into the limiting groove 211 to limit the position of the adapter 3 relative to the main body 2.

[0036] As shown in Figure 9, during the process of assembling the adapter 3 to the main body 2, the limiting protrusion 304 is aligned with the notch 212, and as shown in Figure 10, the adapter 3 can be restricted relative to the main body 2 along the longitudinal direction of the main body 2 by rotating the adapter 3 clockwise so that at least a portion of the limiting protrusion 304 is inserted into the limiting groove 211.

[0037] In some exemplary embodiments, as shown in FIG. 11 , the first water outlet 201b may be a semicircular water nozzle, a small semicircular water nozzle, or a large semicircular water nozzle. In the present embodiment, the small semicircular water nozzle is smaller than half the size of a circular water nozzle, and the large semicircular water nozzle is larger than half the size of a circular water nozzle. The contour line of the first water outlet 201b along a cross section perpendicular to the length of the main body 2 includes an arc portion and a wavy portion, and both the leading and trailing ends of the wavy portion smoothly meet the arc portion. The shape of the second water outlet 202b can be designed with reference to the shape of the first water outlet 201b, and details thereof will be omitted here.

[0038] 11 , the wavy portions of the first water outlet 201b and the second water outlet 202b may be disposed opposite each other, and may be closer to the radial center of the main body 2 than the arc portions. For ease of identification, the arc portion of the first water outlet 201b may be referred to as the first arc portion 201-1, the wavy portion as the first wavy portion 201-2, the arc portion of the second water outlet 202b as the second arc portion 201-3, and the wavy portion as the second wavy portion 201-4.

[0039] In some exemplary embodiments, in a structure in which the flow area of ​​the first water outlet 201b is smaller than the flow area of ​​the second water outlet 202b, the range of the minimum flow area of ​​the second water channel 202 is set to 86.5 mm 2 ~133.0mm 2 The range of the minimum flow area of ​​the first water passage 201 may be set to 16.0 mm 2 ~35.0mm 2 In a structure in which the flow area of ​​the first water outlet 201b is larger than the flow area of ​​the second water outlet 202b, the range of the minimum flow area of ​​the first water channel 201 may be set to 86.5 mm 2 ~133.0mm 2 The range of the minimum flow area of ​​the second water passage 202 may be set to 16.0 mm 2 ~35.0mm 2 The flow area range can be set to 86.5mm 2 ~133.0mm 2The range of the equivalent diameter is set to 10.0 mm to 13.0 mm. The range of the flow area is set to 16.0 mm. 2 ~35.0mm 2 The equivalent circular diameter is set to 4.5 mm to 6.7 mm. In the examples of the present application, the flow surface of the water channel is set to a circle, and the equivalent circular diameter is the diameter corresponding to this circle.

[0040] In addition to the flow areas of the first outlet 201b and the second outlet 202b affecting the jetting effect of the jet head, the effective lengths of the first water passage 201 and the second water passage 202 also affect the jetting effect of the jet head. In the present embodiment, the ratio of the effective length of the water passage to the equivalent circular diameter of the flow area of ​​the water passage is the aspect ratio. For example, as shown in Figures 13, 14, and 15, the effective length is the length of the water passage where the flow area of ​​the water passage along the length of the jet head itself is equal to the flow area of ​​the water passage. As shown in Figures 13, 14, and 15, the effective length of the first water passage 201 may be L1, and the effective length of the second water passage 202 may be L2. For example, as shown in Figure 16, the equivalent circular diameter of the flow area of ​​the first outlet 201b may be D1, and the equivalent circular diameter of the flow area of ​​the second outlet 202b may be D2. The aspect ratio may be set in the range of 3.5 to 5.5. If the aspect ratio is less than 3.5, the spray will diverge and the cleaning function will be poor. If the aspect ratio is more than 5.5, it will cause severe flow restriction and pressure loss, which will also affect the cleaning function.

[0041] The outlet with the larger flow area, either the first or second outlet 201b or 202b, can have a shape as close to a circle as possible, such as a circle or semicircle. This allows the low-speed water jet to maintain a certain thrust and prevent the jet from diverging, forming a smooth siphon in the toilet and removing waste. The outlet with the smaller flow area, either the first or second outlet 201b or 202b, sprays at a high flow rate and a low volume. If the jet of water gathers regularly, this can result in incomplete wastewater displacement and residual dirt. Therefore, the outlet with the smaller flow area, either the first or second outlet 201b or 202b, needs to have an irregular shape to achieve a slightly divergent jet effect. For example, it can be shaped like a crescent, allowing the outlet with the smaller flow area to spray water to clean many areas of the toilet, remove all residual water, and achieve complete wastewater displacement and excellent waste removal performance.

[0042] In another embodiment of the present application, a jet head is provided as shown in Figures 22 to 25. The jet head may include a main body 2 and an adapter 3. The main difference between the jet head according to this embodiment and the jet head according to the above embodiment is that the adapter 3 is fixed to the outer wall of the main body 2. For example, the main body 2 and the adapter 3 may be manufactured by an integral molding method such as casting or injection molding. The adapter 3 may be formed of a hollow cylinder of equal diameter. As the above embodiment can be referred to for other structures of the jet head according to this embodiment, detailed description thereof will be omitted here.

[0043] 24, there is a gap L along the length of the main body 2 between the first water inlet 201a and one end of the partition rib 203 remote from the first water outlet 201b. By setting the gap L, it is possible to reduce the requirement for accuracy in aligning the flow path 301 and the first water inlet 201a, and thus reduce manufacturing costs.

[0044] In another embodiment of the present application, a flushing system is provided as shown in Figures 26 to 29. As shown in Figure 26, two toilet bodies 1 are shown to clearly explain the connection relationship between the flushing system and the toilet body, and do not indicate that two toilet bodies are required to be provided in the flushing system. The flushing system may include a jet head, a first water supply assembly 6, and a second water supply assembly 7 described in any of the above embodiments.

[0045] In actual use, the jet head is attached to the toilet body 1 to supply water to the toilet. The first water supply assembly 6 may be connected to the second water inlet 202a to supply water to the second water channel 202. The second water supply assembly 7 may be connected to the first water inlet 201a to supply water to the first water channel 201. The water supply pressures of the first water supply assembly 6 and the second water supply assembly 7 may be different. For example, the water supply pressure of the first water supply assembly 6 may be greater than the water supply pressure of the second water supply assembly 7. By designing the two water outlets with differentiated flow areas, the flushing effects of the two water supply assemblies can be nearly identical, improving user satisfaction. The combination design using two water channels and two water supply assemblies enhances the versatility of the flushing system product and can meet the needs of different usage scenarios.

[0046] 26, the first water supply assembly 6 may include a first water pipe 601 in communication with the toilet tank 103, a booster pump 602 in communication with the first water pipe 601, and an outlet pipe 603 in communication with the booster pump 602.

Exemplarily, the first water supply assembly 6 may be configured to communicate with the end of the rim water pipe 802 that is not communicating with the rim module 801 to supply water to the toilet rim. Alternatively, the second water supply assembly 7 may be configured to communicate with the end of the rim water pipe 802 that is not communicating with the rim module 801 to supply water to the toilet rim. In the embodiments of the present application, the end of the rim water pipe 802 that is not communicating with the rim module 801 may also be referred to as the water inlet end of the rim waterway.

[0049] In some exemplary embodiments, the flushing system may further include a controller (not shown) and a control valve 9 electrically connected to the controller, the control valve 9 being shown in Figure 26. The controller may be configured to control the control valve to cause at least one of the first water supply assembly and the second water supply assembly to supply water to the toilet body 1.

[0050] A control program may be preset in the controller. The control program may be set according to the actual usage of the toilet. For example, the default setting may be set to supply water from the first water supply assembly 6 to the toilet body 1, and the second water supply assembly 7 may be manually selected to supply water to the toilet body 1, or the first water supply assembly 6 and the second water supply assembly 7 may be switched to supply water to the toilet body 1 together.

[0051] In some exemplary embodiments, as shown in Figure 26, the control valve 9 may include only one mixing valve 901. The controller may control the mixing valve 901 to supply water to the toilet body 1 via the first water supply assembly 6 or the second water supply assembly 7. Alternatively, the control valve 9 may include two check valves, one of which is used to control the first water supply assembly 6 to supply water to the toilet body 1 via the first water supply assembly 6, and the other is used to control the second water supply assembly 7 to supply water to the toilet body 1 via the second water supply assembly 7. Alternatively, the control valve 9 may include two three-way valves. One of the three-way valves is used to control the first water supply assembly 6, which supplies water to the toilet body 1 and rim water to the rim water channel 8, and the other three-way valve is used to control the second water supply assembly 7, which supplies water to the toilet body 1 and rim water to the rim water channel 8. Both of the two check valves or two three-way valves may be electrically connected to a controller, allowing for integrated control. The embodiments of the present application do not limit the specific combination of control valves.

[0052] In some illustrative embodiments, as shown in Figures 26 and 27, the control valve 9 may be configured to include one mixing valve 901 and one distributing valve 902. The mixing valve 901 may be provided with multiple connection ports. As shown in Figure 28, the multiple connection ports may include a first connection port 903, a second connection port 904, a third connection port 905, a fourth connection port 906, and a fifth connection port 907. Exemplarily, the first connection port 903, the second connection port 904, and the distributing valve 902 may be used to realize communication between the second water supply assembly 7 and the jet head. One end of the first connection port 903 may be connected to the water supply pipe 701, the first connection port 903 may be connected to the second connection port 904, the distributing valve 902 may be connected to the second connection port 904, and the distributing valve 902 may be connected to the first water inlet 201a via a water pipe. The water outlet of the first water supply assembly 6 may be connected to the third connection port 905, and by utilizing the valve passage in the mixing valve 901, the first water supply assembly 6 may be connected to the second water inlet 202a via the fifth connection port 907. The fourth connection port 906 may be connected to the rim water pipe 802 and the rim module 801.

[0053] In some exemplary embodiments, the flushing system may further include a detection unit (not shown) electrically connected to the controller. The detection unit may be integrated into the case of the booster pump 602 or into the control board of the smart toilet. The flushing system may further include a backup power supply (not shown). The backup power supply may be electrically connected to the controller, and the backup power supply may be electrically connected to the control valve 9. The detection unit may be configured to detect the voltage at the input end of the booster pump 602 and send it to the controller. When the controller determines that the voltage at the input end of the booster pump 602 is lower than the operating voltage, for example, when the power supply is cut off or the voltage is too low, the controller may be configured to control the backup power supply to realize control of the control valve 9 and control the second water supply assembly 7 to supply water to the toilet body 1 to realize the flushing function. When the controller determines that the voltage at the input end of the booster pump 602 is equal to or higher than the operating voltage, the controller may cut off control of the backup power supply, i.e., not activate the backup power supply. The controller controls the control valve 9 to control the first water supply assembly 6 to supply water to the toilet body 1. By utilizing the interconnection between the installed detection unit, backup power supply, controller and control valve, automatic switching between two different water supply assemblies can be realized, improving the smartness of the product.
