[0050] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0051] The present application provides a spray washing system 1 for an intelligent toilet. Figure 1 and Fig.13 As shown, the spray system 1 for the smart toilet is arranged on the water inlet pipe 2 of the smart toilet.

[0052] The spray system 1 includes a commutator 10 and a plurality of nozzles 20, wherein the commutator 10 includes a cover 11, a drive mechanism 12, and a rotating head 13. The cover 11 has a first pipe 111 that can be connected to the smart toilet water inlet pipe 2. The drive mechanism 12 includes a motor 121 and a gear 122 that is driven and connected to the motor 121.

[0053] The rotating head 13 has a tooth portion 133 meshing with the gear 122 and a water outlet 132 communicating with the first pipe 111. The rotating head 13 is rotatably mounted on the cover body 11 and disposed close to the nozzle 20. The rotating head 13 rotates relative to the cover body 11, so that the water outlet 132 rotates to a different nozzle 20 and communicates with the nozzle 20.

[0054] The rotating head 13 arranged near the nozzle 20 in the commutator 10 can be rotatably installed on the cover body 11. As the rotating head 13 rotates, the water outlet 132 can be connected with different nozzles 20, thereby realizing water path switching at each nozzle 20, which not only reduces the use of pipelines and reasonably utilizes space, but also shortens the distance from the water inlet to the nozzle, avoids cold water accumulation, and improves user experience.

[0055] Specifically, Figure 2 As shown, the plurality of nozzles 20 include a female washing nozzle 21, a fecal washing nozzle 22, and a laxative nozzle 23. The three nozzles 21, 22, and 23 are integrated on a base 24, thereby saving space and optimizing the overall structure of the nozzle. The female washing nozzle 21, the fecal washing nozzle 22, and the laxative nozzle 23 are arranged in a straight line on the base 24, and there is a certain interval between them to avoid interference during the water spraying operation and affect the user's experience.

[0056] like Figure 3 and Figure 4 As shown, the cover body 11 includes an outer cover 110 and a first pipe 111 , wherein the outer cover 110 is a rectangular parallelepiped structure with one side being curved, and a recess 1101 is formed at the middle position of the top surface of the outer cover 110 .

[0057] The first pipe 111 is a right-angle elbow, and the two ends are respectively a first end and a second end. The first end passes through the middle position of the bottom of the outer cover 110 and passes through the recess 1101 to communicate with the water outlet 132 on the rotating head 13, and the second end can be connected to the water inlet pipe 2 of the smart toilet. The cover body 11 of such a structure has a novel shape and a simple and reasonable structure. The first pipe 111 in the cover body 11 and the outer cover 110 can be made of plastic and integrally formed by injection molding.

[0058] like Figures 5 to 8 As shown, the rotating head 13 includes a truncated cone body 130 with a hollow interior and a circular tube body 140. A circular through hole 131 is provided at the center of the upper bottom surface of the truncated cone body 130, and a water outlet 132 is provided on the lower bottom surface of the truncated cone body 130. A plurality of helical teeth having the same inclination angle as the side surface are provided on the side surface of the truncated cone body 130, and the helical teeth constitute a tooth portion 133 meshing with the gear 122. The helical teeth constituting the tooth portion 133 may be distributed all over the side surface of the truncated cone body 130, or as shown in the present embodiment, the helical teeth may be distributed on part of the side surface of the truncated cone body 130. The rotating head 13 realizes the alignment and connection of the water outlet 132 with different nozzles 20 by rotation, and therefore, the layout of the helical teeth may be set according to the angle at which the rotating head 13 needs to rotate.

[0059] The circular through hole 131 and the water outlet 132 on the truncated cone body 130 are communicated with the hollow cavity inside the truncated cone body 130 , and the water outlet 132 is eccentrically arranged relative to the center of the lower bottom surface of the truncated cone body 130 .

[0060] One end surface of the circular tube 140 is in contact with the upper bottom surface of the truncated cone body 130, and the circular tube 140 is coaxially arranged with the truncated cone body 130. In this embodiment, the rotating head 13 is made of plastic, and the truncated cone body 130, the tooth portion 133 and the circular tube 140 are integrally connected and can be formed by injection molding.

[0061] like Figure 1 As shown, the first end of the first pipe 111 in the cover body 11 is inserted into the circular tube body 140 in the rotating head 13, and the circular tube body 140 and the truncated cone body 130 thereon can rotate on the first end of the first pipe 111. Preferably, the inner circumference of the circular tube body 140 and the outer circumference of the first end of the first pipe 111 are sealed and connected by a first sealing ring 10a sleeved on the first end.

[0062] The circular tube body 140 is connected to the first pipe 111 at the first end, and the first pipe 111 is connected to the water inlet pipe 2 of the smart toilet at the second end. The water enters from the circular tube body 140, then flows into the cavity of the truncated cone body 130 from the circular through hole 131 of the truncated cone body 130, and finally sprays out from the water outlet 132.

[0063] like Figure 1 and Fig. 9 As shown, the driving mechanism 12 includes a motor 121 and a gear 122 drivingly connected to the motor 121. The gear 122 is preferably a bevel gear, so that it can mesh with the tooth portion 133 composed of helical teeth on the rotating head 13 to realize the power transmission between the two perpendicular intersecting axes. In addition to the above-mentioned helical gear transmission, a spur gear with an appropriate tooth pitch and a tooth portion 133 composed of spur teeth can also be selected to realize the power transmission between the two intersecting axes. In addition, a worm gear can also be used to realize the above-mentioned function.

[0064] The driving mechanism 12 also includes a transmission shaft 123 that is respectively connected to the motor 121 and the gear 122. One end of the transmission shaft 123 is coaxially fixedly connected to the gear 122, and the other end is connected to the output end of the motor 121. By setting the transmission shaft 123, the torque output by the motor 121 can be efficiently and conveniently transmitted to the gear 122, and the position of the motor 121 can also be reasonably arranged. In this embodiment, the material of the transmission shaft 123 and the gear 122 are both plastic, and the two are connected into one body, which can be injection molded.

[0065] like Figure 1As shown, the commutator 10 further includes an electric control board 14, and the motor 121 is control-connected to the electric control board 14. By setting the electric control board 14, the need for precise control of the rotation speed, torque, etc. of the motor 121 can be met.

[0066] The motor 121 drives the gear 122 (bevel gear) to rotate through the transmission shaft 123, and the tooth portion 133 (helical gear) on the rotating head 13 is engaged with the gear 122. The rotating head 13 rotates with the rotation of the gear 122. The water outlet 132 on the rotating head 13 can be rotated to positions corresponding to the feminine washing nozzle 21, the toilet washing nozzle 22, and the laxative nozzle 23, and can be connected to the corresponding nozzles so that the incoming water can be sprayed out from the nozzles for spray washing operations.

[0067] like Figure 1 and Fig.11 As shown, the commutator 10 also includes a fixing seat 15 buckled on the cover body 11, and second pipes 151, 152, and 153 corresponding to the female washing nozzle 21, the fecal washing nozzle 22, and the defecation nozzle 23 are respectively opened in the fixing seat 15, and each second pipe is connected to a nozzle. For example, the second pipe 151 is connected to the female washing nozzle 21, the second pipe 152 is connected to the fecal washing nozzle 22, and the second pipe 153 is connected to the defecation nozzle 23.

[0068] like Fig.10 As shown, the fixing seat 15 includes a main body 154 of a rectangular parallelepiped structure and a boss 155 disposed on the main body 154, and the bottom surface of the boss 155 is in contact with the top surface of the main body 154. Three second pipes 151, 152, and 153 pass through the main body 154 and the boss 155 and extend to the outside of the boss 155, and the parts extending to the outside of the boss 155 are connected to form a pipe platform 156. The female washing nozzle 21, the toilet washing nozzle 22, and the laxative nozzle 23 are buckled on the boss 155 and the pipe platform 156 together with the base 24.

[0069] The pipe platform 156 is provided with a first groove 1561, a second groove 1562, and a third groove 1563, wherein the second groove 1562 is connected to the second pipe 152 corresponding to the toilet nozzle 22, the first groove 1561 is connected to the second pipe 151 corresponding to the women's washing nozzle 21, and the third groove 1563 is connected to the second pipe 153 corresponding to the defecation nozzle 23. The second groove 1562 is located between the first groove 1561 and the third groove 1563, and the first groove 1561 and the third groove 1563 both extend horizontally in a direction away from the second groove 1562. Before the incoming water enters different nozzles from the second pipes 151, 152, 153 respectively, the first, second, and third grooves 1561, 1562, 1563 play a role in guiding the flow, and the opening areas of the first, second, and third grooves 1561, 1562, 1563 are larger, which is convenient for aligning the connecting nozzles, and avoids affecting the spraying effect of the nozzles due to misalignment.

[0070] like Fig.11 As shown, a first concave cavity 1541 is provided at the lower portion of the body 154 , the second pipes 151 , 152 , 153 are connected to the first concave cavity 1541 , and the rotating head 13 is placed in the first concave cavity 1541 .

[0071] like Figure 3 As shown, the cover body 11 further includes three first threaded sleeves 112, which are evenly arranged on the outer surface of the outer cover 110. Fig.10 and Fig.11 As shown, a second threaded sleeve 1545 corresponding to the first threaded sleeve 112 is provided on the outer surface of the first concave cavity 1541. The cover body 11 is buckled on the first concave cavity 1541, and the bolt 17 passes through the first threaded sleeve 112 and is fastened to the second threaded sleeve 1545, thereby achieving the locking of the cover body 11 and the first concave cavity 1541. The transmission shaft 123 and the gear 122 thereon pass through the cover body 11 and the gear 122 in the recess 1101 of the outer cover 110 and the first concave cavity 1541 to achieve meshing with the rotating head 13.

[0072] like Figure 1 As shown, the outer cover 110 and the first concave cavity 1541 are sealed and connected via a second sealing ring 10b, and the transmission shaft 123 and the outer cover 110 and the first concave cavity 1541 are sealed and connected via a third sealing ring 10c.

[0073] like Fig.11 As shown, the lower part of the body 154 is also provided with a second cavity 1542 for accommodating the transmission shaft 123, a third cavity 1543 for accommodating the motor 121, and a fourth cavity 1544 for accommodating the electric control board 14. The arrangement of these cavities provides a placement space for the transmission shaft 123, the motor 121, and the electric control board 14 to play a protective role.

[0074] like Figure 1 and Fig.12 As shown, the commutator 10 also includes a protective cover 16 that is buckled on the fixing seat 15 and surrounds the motor 121 and the electric control board 14. The protective cover 16 includes a cover shell 161 and a plurality of clamping columns 162, wherein the cover shell 161 is a square shell-like structure with a rectangular plate at the bottom, surrounded on all sides, and an opening at the top. The cover shell 161 is buckled with the body 154 of the fixing seat 15, and the cover shell 161 and the fixing seat 15 are locked by bolt connection. The cover shell 161 and the body 154 of the fixing seat 15 are sealed and connected by a fifth sealing ring (not shown in the figure).

[0075] The transmission shaft 123, the motor 121, and the electric control board 14 are placed between the cover shell 161 and the body 154, and the transmission shaft 123 is sealed and connected to the cover shell 161 and the body 154 through the fourth sealing ring 10d. The clamping column 162 is arranged in the cover shell 161, and the position of the motor 121 and the electric control board 14 is limited by the clamping column 162 to prevent the motor 121 and the electric control board 14 from shaking during operation and affecting the normal operation of the spray washing system 1.

[0076] like Fig.14 As shown, another embodiment of the present invention provides a spray head for a smart toilet, comprising a housing 3 and the above-mentioned spray system 1. The housing 3 is a tube structure with a closed front end and an open rear end, and the spray system 1 is installed in the housing 3. The female washing nozzle 21, the fecal washing nozzle 22, the defecation nozzle 23 and the base 24 in the spray system 1 are fixed at the front end of the housing 3, and the female washing nozzle 21, the fecal washing nozzle 22, and the defecation nozzle 23 extend outside the housing 3.

[0077] Another embodiment of the present invention provides a smart toilet, including a water inlet pipeline 2 and the above-mentioned nozzle.

[0078] After the above-mentioned spraying system 1 is assembled, the water inlet pipe 2 is connected to the second end of the first pipe 111 in the spraying system 1, and then the spraying system 1 with the water inlet pipe 2 is installed as a whole into the shell 3. Finally, the nozzle is installed into the smart toilet, and the electronic control board 14 is connected to the smart toilet controller through the line.

[0079] The user can select any of the three modes of feminine washing, fecal washing and laxative through the buttons on the smart toilet. The following describes the working process of the spray washing system 1 in detail using feminine washing as an example:

[0080] When the user selects the toilet-washing mode through the button on the smart toilet, the smart toilet controller sends an electrical signal to the electric control board 14, and the electric control board 14 controls the motor 121 to rotate, and the motor 121 drives the transmission shaft 123 and the gear 122 to rotate, and the rotating head 13 meshed with the gear 122 through the tooth portion 133 rotates, and the water outlet 132 on the rotating head 13 rotates to a position connected with the second pipe 152 in the fixed seat 15. At this time, the water in the water inlet pipeline 2 enters from the circular tube body 140 of the rotating head 13, and then flows into the cavity of the truncated cone body 130 from the circular through hole 131 of the truncated cone body 130, and then the water is sprayed from the water outlet 132 into the second pipe 152, and finally sprayed out from the toilet-washing nozzle 22 to clean the user.

[0081] The above is only an example of the toilet washing mode. The working process of the feminine washing and laxative modes is the same as that of the toilet washing mode, so it will not be repeated here.

[0082] In the smart toilet and its spraying system and nozzle provided in this embodiment, the rotating head 13 disposed near the nozzle 20 in the diverter 10 can be rotatably mounted on the cover body 11, and as the rotating head 13 rotates, the water outlet 132 can be connected with different nozzles 20. By switching the water path at each nozzle 20, the amount of pipes is reduced, the space is reasonably utilized, and the distance from the water inlet to the nozzle is shortened, cold water accumulation is avoided, and the user experience is improved.

[0083] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
