The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0055] This embodiment provides a flushing system and a toilet, such as Figure 1 and Figure 7 As shown, the toilet includes a toilet body 100 and a flushing system provided in this embodiment. The flushing system is disposed in the installation space 101 of the toilet body 100 and communicates with the nozzle of the toilet body 100, so that flushing water can be delivered to the flushing chamber 102 of the toilet body 100 through the nozzle.

[0056] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the flushing system provided in this embodiment includes a water tank 1, a water pump 2, and a pipe assembly 3. The water tank 1 is disposed within the installation space 101 of the toilet body 100, and a connecting portion is provided on the upper side wall of the water tank 1. The water pump 2 is disposed at the bottom of the inner cavity of the water tank 1. A portion of the pipe assembly 3 is located inside the water tank 1 and communicates with the outlet of the water pump 2. Another portion of the pipe assembly 3 is connected to the connecting portion in a horizontal or vertical direction, extends out of the water tank 1 from the connecting portion, and extends away from the water tank 1. One end of the pipe assembly 3 extending out of the water tank 1 is connected to the nozzle of the toilet body 100.

[0057] In other words, in this embodiment, by directly placing the water pump 2 inside the water tank 1, the space occupied by the flushing system within the toilet body 100 can be effectively saved without affecting the installation of other components (such as the seat cover mechanism), thus significantly improving space utilization. On the other hand, eliminating the external rubber hose connecting the water pump 2 to the water tank 1 and optimizing the layout of the pipe assembly 3 effectively reduces flushing pipe resistance, improves flushing performance, and lowers operating costs.

[0058] Optionally, refer to Figures 2-6In one embodiment, the connection includes a transition boss 11 extending away from the sidewall of the water tank 1. The pipe assembly 3 includes a water supply pipe 31 and a water outlet pipe 32. One end of the water supply pipe 31 is connected to the outlet of the water pump 2, and the other end of the water supply pipe 31 is connected to the water outlet pipe 32. The water outlet pipe 32 passes horizontally through the transition boss 11, and the end of the water outlet pipe 32 away from the water supply pipe 31 is connected to the nozzle of the toilet body 100. That is, water in the water tank 1 enters the pump body of the water pump 2 through the inlet of the water pump 2, and is then pumped through the outlet of the water pump 2 to the water supply pipe 31 and the water outlet pipe 32, and finally sprayed out through the nozzle of the toilet body 100 to act on the surface of the bowl in the flushing chamber 102. The water outlet pipe 32 extends horizontally through the water tank 1, maximizing the utilization of the tank's volume and facilitating the switching between various flushing modes, such as allowing users to choose between Level 2 and Level 1 water efficiency modes. In other words, users can select the flush volume based on their actual needs within the water tank 1's capacity, thus achieving water conservation.

[0059] Specifically, such as Figure 3 , Figure 4 and Figure 6 As shown, the adapter boss 11 has a threaded hole 111 along the horizontal direction, and the water outlet pipe 32 has an external threaded section 321 and a stop ring 322. The external threaded section 321 on the water outlet pipe 32 can be threadedly connected to the threaded hole 111 of the adapter boss 11, so that the stop ring 322 abuts against the end face of the adapter boss 11. The stop ring 322 is located downstream of the external threaded section 321, with the downstream direction of the external threaded section 321 as a reference to the water flow direction in the water outlet pipe 32. The stop ring 322 is used to limit the depth of the portion of the water outlet pipe 32 inserted into the water tank 1, preventing the water outlet pipe 32 from being inserted too deeply and occupying the volume of the water tank 1.

[0060] Furthermore, a sealing ring 33 is provided between the stop ring 322 and the adapter boss 11, and is fitted onto the water outlet pipe 32. The sealing ring 33 can prevent water in the water tank 1 from leaking out from the connection between the adapter boss 11 and the water outlet pipe 32, ensuring the airtightness of the water tank 1. For example, the sealing ring 33 can be a rubber ring or a silicone ring, etc.

[0061] Optionally, refer to Figures 8-12In another embodiment, the connecting part includes a transition platform 12 formed by an inward recess from the side wall of the water tank 1, with a through hole vertically formed on the transition platform 12. The connecting part also includes a first insertion pipe 13 extending vertically upward from the peripheral side of the through hole opening and a second insertion pipe 14 extending vertically downward from the peripheral side of the through hole opening. The pipe assembly 3 includes a water supply pipe 31 and a water outlet pipe 32. One end of the water supply pipe 31 is connected to the outlet of the water pump 2, and the other end of the water supply pipe 31 is connected to the first insertion pipe 13. One end of the water outlet pipe 32 is connected to the second insertion pipe 14, and the other end of the water outlet pipe 32 is connected to the nozzle of the toilet body 100. In other words, water in tank 1 enters pump body 2 through inlet, then is pumped to supply pipe 31 through outlet, and flows sequentially through first connector 13, through hole, second connector 14, and outlet pipe 32, finally being sprayed out through nozzle of toilet body 100 to act on the bowl surface in flushing chamber 102. Positioning the connection between supply pipe 31 and outlet pipe 32 vertically facilitates smooth water flow.

[0062] Specifically, the first insertion connector 13 is inserted into the water supply pipe 31, with an interference fit between the first insertion connector 13 and the water supply pipe 31. Correspondingly, the second insertion connector 14 is inserted into the water outlet pipe 32, with an interference fit between the second insertion connector 14 and the water outlet pipe 32. The insertion connection method is easy to operate, and the interference fit ensures the reliability and sealing of the connection.

[0063] Optionally, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the flushing system also includes an inlet valve 6. The inlet valve 6 is located inside the water tank 1, and its inlet end is connected to an external water source via an inlet pipe 61. Exemplarily, the inlet valve 6 can be a mechanical inlet valve 6 as used in the prior art, the structure and principle of which will not be described here.

[0064] Furthermore, to prevent the water tank 1 from overflowing due to the failure of the inlet valve 6, an overflow port 17 is formed on the side of the water tank 1 near the flushing chamber 102 of the toilet body 100, which communicates with the flushing chamber 102. This allows excess water in the water tank 1 to flow directly into the flushing chamber 102 from the overflow port 17, preventing water in the water tank 1 from soaking other components of the smart toilet and avoiding water damage that could cause the smart toilet to malfunction.

[0065] Optionally, continue to refer to Figure 5 , Figure 6 , Figure 11 and Figure 12The bottom surface of the water tank 1 is provided with mounting posts 15, and the pump body of the water pump 2 is fitted with a mounting bracket 4. The mounting bracket 4 is connected to the mounting posts 15 by fasteners. Specifically, the top two sides of the mounting bracket 4 are provided with connecting lugs, and the bottom surface of the water tank 1 is provided with two corresponding mounting posts 15. The connecting lugs have through holes, and the top of the mounting post 15 has a threaded connection hole. Fasteners such as bolts or screws pass through the through holes on the connecting lugs and are screwed into the threaded connection holes on the corresponding mounting posts 15. The fastener screw connection method facilitates subsequent maintenance and replacement of the water pump 2.

[0066] Furthermore, in this embodiment, after the water pump 2 is installed on the water tank 1 via the mounting bracket 4, there is a gap between the lowest point of the water pump 2 and the bottom surface of the water tank 1. With this arrangement, the water pump 2 does not directly contact the bottom surface of the water tank 1, and when the water pump 2 is working, its vibration will not generate noise between it and the water tank 1, thus improving the user experience.

[0067] Furthermore, a filter element 16 is provided on the bottom surface of the water tank 1, and the filter element 16 is spaced apart from the water inlet of the water pump 2. The filter element 16 can prevent impurities from entering the water pump 2, which helps to protect the structure of the water pump 2 and thus improves the service life of the water pump 2. For example, the filter element 16 can be a filter grille or a filter screen, etc.

[0068] Optionally, such as Figure 6 and Figure 12 As shown, the flushing system also includes an exhaust assembly 5. The exhaust assembly 5 is mounted on the pipe assembly 3 and is used to expel gas from within the pipe assembly 3. When the flushing system is installed within the installation space 101 of the toilet body 100, and the pipe assembly 3 connects the water tank 1 and the nozzle of the toilet body 100, after the water in the water tank 1 flows smoothly through the pipe assembly 3 into the flushing chamber 102, the exhaust assembly 5 can expel the exhaust gas from the pipe assembly 3, preventing gas from entering the flushing chamber and producing a "gurgling" noise, thus ensuring a better user experience.

[0069] For example, the exhaust assembly 5 can be selected as any one of the following structures: elastic plug, vacuum breaker, or exhaust valve. Elastic plug, vacuum breaker, or exhaust valve are all prior art, and will not be described in detail in this embodiment.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
