[0035] To make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other in any manner.

[0036] The water from the toilet ring is often sprayed out through the ring washing nozzle. The conventional ring washing nozzle is generally a straight tube hollow structure, one end is connected to the toilet, and the other end is a water inlet hole, usually facing the back of the toilet.

[0037] As smart toilets have more and more functions, the number of internal components of the electronic cover is also increasing. In order to better arrange the electronic cover, many electronic covers will choose to sink to utilize the space at the back of the toilet. In this way, there will be a problem that there is no space for the conventional ring washing nozzle to take over the water inlet.

[0038] Please combine Figures 1 to 4 The toilet provided by the embodiment of the present disclosure is now described. The toilet includes a toilet body 10 and a rim-washing nozzle assembly 20. The toilet body 10 may be made of ceramic for easy cleaning. The toilet body 10 is provided with a rim-washing water channel 100 and a mounting hole 200 connected to the rim-washing water channel 100.

[0039] The ring washing nozzle assembly 20 includes a first tube body 21 and a second tube body 22. The first tube body 21 has a first tube hole 301 and a water outlet hole 302. A second tube hole 401 and a first water inlet hole 402 are respectively provided at both ends of the second tube body 22. The axial direction of the second tube hole 401 intersects with the axial direction of the first water inlet hole 402 and forms a certain angle. The second tube body 22 can rotate relative to the first tube body 21, and a sealing ring 40 is provided between the first tube body 21 and the second tube body 22 to ensure the sealing of the first tube body 21 and the second tube body 22, to ensure that after the second tube body 22 rotates relative to the first tube body 21, the sealing reliability between the first tube body 21 and the second tube body 22 can still be ensured, to avoid water overflowing from between the first tube body 21 and the second tube body 22 after subsequent water flow. The first tube hole 301 and the second tube hole 401 are connected.

[0040] The toilet bowl cleaning nozzle assembly 20 is mounted in the mounting hole 200, connecting the water outlet 302 to the toilet bowl cleaning waterway 100. The first water inlet 402 can be connected to the toilet water tank or tap water network via the external pipe 30. A control valve can be installed in the first water inlet 402 or the external pipe 30 to control the flow of water into the toilet bowl cleaning nozzle assembly 20 and into the toilet bowl cleaning waterway 100 through the water outlet 302. Under the guidance of the toilet bowl cleaning waterway 100, the entire toilet bowl surface 11 is cleaned.

[0041] In summary, the implementation of the embodiments of the present disclosure will have the following beneficial effects:

[0042] The ring-washing nozzle assembly 20 of the above-mentioned solution is applied to a toilet. In addition to providing the toilet with excellent ring-washing water output efficiency, it also facilitates the connection of the water inlet. Specifically, the ring-washing nozzle assembly 20 includes a first tube body 21 having a first tube hole 301 and a water outlet hole 302, and a second tube body 22 having a second tube hole 401 and a first water inlet hole 402 at both ends. The second tube body 22 can rotate relative to the first tube body 21, and a sealing ring 40 is provided between the first tube body 21 and the second tube body 22. The first tube hole 301 and the second tube hole 401 are connected, so that water can be discharged from the first water inlet hole 402 through the second tube body 22 and the first tube body 21 and then out of the water outlet 302 to form ring-washing water. The axial direction of the second pipe hole 401 intersects with the axial direction of the first water inlet hole 402 and forms a certain angle, which facilitates driving the second tube body 22 to rotate relative to the first tube body 21 and by driving the second tube body 22, the ring washing nozzle assembly 20 rotates as a whole, changing the position of the first water inlet hole 402, facilitating the connection between the first water inlet hole 402 and the external pipeline 30, completing the takeover, and will not interfere with the sunken part of the electronic cover.

[0043] In the exemplary embodiment, please combine Figure 2 and Figure 4 The first tube body 21 and the second tube body 22 are threadedly connected, and one of the first tube body 21 and the second tube body 22 is sleeved on the other. This sleeve connection of the first tube body 21 and the second tube body 22 can increase the overlapping area of ​​the first tube body 21 and the second tube body 22, so that the threaded connection between the first tube body 21 and the second tube body 22 can ensure a stable connection and enable the second tube body 22 to rotate relative to the first tube body 21 within a certain range. The first tube body 21 can be sleeved on the second tube body 22. The second tube body 22 can also be sleeved on the first tube body 21.

[0044] In the embodiment of the present disclosure, the second tube body 22 is a curved tube, which is convenient for receiving external force to change the position of the first water inlet hole 402 and is convenient for manually threading the first tube body 21 and the second tube body 22 together.

[0045] In an exemplary embodiment, please refer to Figure 2 and Figure 4 One end of the first tube body 21 has a connecting section 211, which encloses the first tube hole 301. The connecting section 211 has an external threaded surface 2111 and an annular groove 500 on its circumferential outer side. The external threaded surface 2111 is located near the second tube body 22, that is, the annular groove 500 is located on the side of the external threaded surface 2111 away from the second tube body 22.

[0046] The second tube body 22 includes a main body 221 and a sleeve portion 222 . The first water inlet 402 is provided at one end of the main body 221 , and the sleeve portion 222 is provided at the other end of the main body 221 .

[0047] The sleeve portion 222 encloses and forms the second tube hole 401 . An internal thread surface 2221 and a clamping surface 2222 are provided on the circumferential inner side of the sleeve portion 222 . The clamping surface 2222 is provided close to the first tube body 21 , that is, the internal thread surface 2221 is located on the side of the clamping surface 2222 away from the first tube body 21 .

[0048] The first tube body 21 and the second tube body 22 are threadedly connected via the internal threaded surface 2221 and the external threaded surface 2111. The clamping surface 2222 is able to fit against the circumferential outer side of the first tube body 21 and clamp the sealing ring 40 in the annular groove 500. Due to the positional relationship among the external threaded surface 2111, the annular groove 500, the internal threaded surface 2221, and the clamping surface 2222, during the process of screwing the external threaded surface 2111 and the internal threaded surface 2221 in and out of the threaded connection, the internal threaded surface 2221 does not contact the sealing ring 40 and thus damage the sealing ring 40, thereby ensuring the sealing reliability of the sealing ring 40. Furthermore, during the rotation of the external threaded surface 2111 relative to the internal threaded surface 2221, the clamping surface 2222 is able to fit against the circumferential outer side of the first tube body 21, thereby ensuring the stability of the rotation of the external threaded surface 2111 relative to the internal threaded surface 2221. Furthermore, the relatively smooth clamping surface 2222 can slide relative to the sealing ring 40 and, without damaging the sealing ring 40, clamp the sealing ring 40 in the annular groove 500, thereby ensuring the positional stability of the sealing ring 40. In the disclosed embodiment, the clamping surface 2222 is a cylindrical surface coaxially arranged with the internal threaded surface 2221 and the external threaded surface 2111. The sealing ring 40 is made of an elastomeric material. The clamping surface 2222 clamps the sealing ring 40 in the annular groove 500, compressing and deforming the sealing ring 40, increasing the contact surface area between the sealing ring 40, the clamping surface 2222, and the first tube 21, and improving sealing stability.

[0049] In an exemplary embodiment, please refer to Figure 2 and Figure 4The first tube body 21 is a straight tube, and the first tube hole 301 and the water outlet hole 302 are located at the two ends of the first tube body 21, respectively, so that the first tube body 21 can have water inlet at one end and outlet at the other end. In the disclosed embodiment, the cross-section of the first tube body 21 is a circular ring. It is understood that in other embodiments, the cross-section of the first tube body 21 can also have other regular or irregular ring structures.

[0050] A first clamping wall 212 is provided at one end of the first tube body 21 away from the connecting section 211. The first clamping wall 212 is provided on the circumferential outer side of the first tube body 21, so that there is a certain distance between the first clamping wall 212 and the external threaded surface 2111 and the annular groove 500, which facilitates the threaded connection between the external threaded surface 2111 and the internal threaded surface 2221 and the clamping surface 2222 clamping the sealing ring 40 in the annular groove 500.

[0051] A second clamping wall 223 is provided on the circumferential outer side of the sleeve portion 222 and is located at an end of the sleeve portion 222 away from the first water inlet hole 402, such that the second clamping wall 223 is located at the end of the sleeve portion 222. Furthermore, the first tube 21 is a straight tube, and the external threaded surface 2111 located on the circumferential outer side of the connecting section 211 and the internal threaded surface 2221 located on the circumferential inner side of the sleeve portion 222 can be threadedly connected, so that the first clamping wall 212 and the second clamping wall 223 can be arranged along the axial direction of the first tube 21.

[0052] The first tube body 21 and the second tube body 22 are threadedly connected by the internal thread surface 2221 and the external thread surface 2111, and the distance between the first clamping wall 212 and the second clamping wall 223 can be adjusted. In this way, the inner tank 12 of the toilet body 10 forming the ring washing water channel 100 can be clamped by relying on the cooperation of the first clamping wall 212 and the second clamping wall 223, and the ring washing nozzle assembly 20 can be fixed to the toilet body 10.

[0053] In an exemplary embodiment, please refer to Figure 2 and Figure 4 The first clamping wall 212 has a first surface facing the second clamping wall 223 , and the second clamping wall 223 has a second surface facing the first clamping wall 212 .

[0054] An annular elastic pad 50 is provided on at least one of the first and second surfaces. The annular elastic pad 50 is sleeved around the circumferential outer side of the first tube 21. The annular elastic pad 50 acts as a buffer when the first and second clamping walls 212, 223 clamp the inner liner 12, preventing damage to the inner liner 12. In the disclosed embodiment, the annular elastic pad 50 is provided on the first surface. The sealing ring 40 and the annular elastic pad 50 are sleeved on the first tube 21, and the sealing ring 40 is installed in the annular groove 500. The annular elastic pad 50 is in contact with the first surface. After that, the entire body is installed in the mounting hole 200 located in the inner liner 12, and the connecting section 211 is extended from the mounting hole 200 and placed on the rear side of the toilet body 10. The second tube 22 is threadedly connected to the outer threaded surface 2111 through the internal threaded surface 2221 and continuously screwed into the first tube 21. The clamping surface 2222 passes through the sealing ring 40, clamping the sealing ring 40 in the annular groove 500 and sliding relative to the sealing ring 40. After that, the second clamping wall 223 abuts the inner liner 12. The second tube 22 continues to screw in, driving the first tube 21 to move toward the second tube 22, so that the first clamping wall 212 can clamp the annular elastic pad 50 to the inner liner 12 and seal the mounting hole 200. Before the first clamping wall 212 and the inner container 12 completely clamp the annular elastic pad 50, the first tube 21 can rotate relative to the mounting hole 200 to adjust the position of the first water inlet 402, facilitating connection with the external pipe 30 and completing the pipe connection. This allows the second tube 22 to both lock the nut and adjust the angle of the first water inlet 402, facilitating connection with the external pipe 30 without interfering with the sunken portion of the electronic cover.

[0055] In an exemplary embodiment, please refer to Figure 2 and Figure 4 A limiting surface 224 is provided on the inner circumferential side of the sleeve portion 222. The limiting surface 224 is provided on the side of the internal threaded surface 2221 away from the clamping surface 2222 and faces the connecting section 211. The limiting surface 224 abuts against the connecting section 211 to control the position of the first tube 21 extending into the second tube 22, thereby preventing the gap between the first clamping wall 212 and the second clamping wall 223 from being too small, thereby preventing the inner liner 12 from being damaged by the clamping.

[0056] In an exemplary embodiment, please refer to Figure 2 and Figure 4 The wall thickness of the sleeve portion 222 is greater than the thickness of the main body 221, which can improve the strength of the sleeve portion 222 and prevent the sleeve portion 222 from being deformed, thereby improving the threaded connection stability of the internal thread surface 2221 and the external thread surface 2111, improving the clamping stability of the clamping surface 2222 and the first tube body 21 on the sealing ring 40, and improving the abutment stability of the second clamping wall 223 on the inner liner 12.

[0057] In the exemplary embodiment, please combine Figure 3 and Figure 4 The second tube body 22 is also provided with at least one second water inlet hole 403. The axial direction of the first water inlet hole 402 and the axial direction of the at least one second water inlet hole 403 intersect and form a certain angle, so that the toilet bowl washing nozzle assembly 20 has at least two water inlets, which facilitates water and an aqueous solution containing a cleaning medium to enter the toilet bowl washing nozzle assembly 20 together and be sprayed into the toilet bowl washing water channel 100 to clean the toilet bowl surface 11. In the embodiment of the present disclosure, the number of second water inlet holes 403 is one, and the second water inlet hole 403, the second tube hole 401, the first tube hole 301 and the water outlet hole 302 are coaxially arranged. The axial direction of the second tube hole 401 and the axial direction of the first water inlet hole 402 are at an angle of 90°. It can be understood that in other embodiments, the axial direction of the second water inlet hole 403 can also intersect and form a certain angle with the axial direction of the second tube hole 401, and the axial angle between the axial direction of the second tube hole 401 and the axial direction of the first water inlet hole 402 can also be other values.

[0058] In the exemplary embodiment, please combine Figure 2 and Figure 4 The second tube body 22 is provided with an anti-slip portion 225, and the anti-slip portion 225 is configured to be connected to the external pipeline 30 to ensure the connection stability between the second tube body 22 and the external pipeline 30. In the embodiment of the present disclosure, in order to more conveniently connect with the second tube body 22, the external pipeline 30 can be a hose. The anti-slip portion 225 is annular and surrounds the axial direction of the second tube body 22, and is located on the circumferential outside of the second tube body 22. The anti-slip portion 225 gradually narrows toward the side of the first water inlet hole 402 to facilitate plugging with the hose, so that one end of the hose can pass over the anti-slip portion 225 and wrap the anti-slip portion 225. Under the action of the anti-slip portion 225, the hose can produce elastic deformation, thereby increasing the connection surface area between the hose and the second tube body 22, and improving the connection stability between the hose and the second tube body 22.
