[0067] Typical implementation modes reflecting 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 implementation modes, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than to limit the present invention.

[0068] As Figure 1 and Figure 13 shown, the present application provides a spray washing system 1 for a smart toilet, which is arranged on the water inlet pipeline 2 of the smart toilet. The spray washing system 1 includes a commutator 10 and a plurality of nozzles 20.

[0069] The commutator 10 is arranged close to the nozzles and is connected to each nozzle 20. The commutator 10 can be connected to the water inlet pipeline 2 of the smart toilet to switch the incoming water to different nozzles 20.

[0070] The commutator 10 is arranged close to the nozzles 20 to realize water path switching at each nozzle 20, which not only reduces the amount of pipelines used, rationally utilizes the space, but also shortens the distance of the incoming water flowing to the nozzles, avoids the accumulation of cold water, and improves the user experience.

[0071] An embodiment, as Figure 1 shown, the spray washing system 1 includes a commutator 10 and a plurality of nozzles 20. Among them, the commutator 10 includes a cover body 11, a driving mechanism 12, and a rotating head 13. The cover body 11 has a first pipeline 111 that can be connected to the water inlet pipeline 2 of the smart toilet. The driving mechanism 12 includes a motor 121 and a gear 122 that is drivingly connected to the motor 121.

[0072] 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 11 and is disposed close to the nozzle 20. The rotating head 13 rotates relative to the cover 11 to rotate the water outlet 132 to different nozzles 20 and communicate with the nozzles 20.

[0073] The rotating head 13 disposed close to the nozzle 20 in the commutator 10 is rotatably mounted on the cover 11. As the rotating head 13 rotates, the water outlet 132 can communicate with different nozzles 20, thereby realizing water path switching at each nozzle 20, reducing the amount of pipes used, rationally utilizing space, shortening the distance of the incoming water flowing to the nozzle, avoiding cold water accumulation, and improving the user experience.

[0074] Specifically, as Figure 2 shown, the multiple nozzles 20 include a feminine wash nozzle 21, a bidet nozzle 22, and an enema nozzle 23. These three nozzles 21, 22, and 23 are integrated on a base 24, thereby saving space and optimizing the overall structure at the nozzle. The feminine wash nozzle 21, the bidet nozzle 22, and the enema nozzle 23 are arranged in a straight line on the base 24 and have a certain interval between them to avoid interference during the spraying operation and affect the user experience.

[0075] As Figure 3 and Figure 4 shown, the cover 11 includes an outer cover 110 and a first pipe 111. The outer cover 110 is a rectangular parallelepiped structure with an arc on one side, and a depression 1101 is formed at the middle position of the top surface of the outer cover 110.

[0076] The first pipe 111 is a right-angle elbow pipe, and the two ends are respectively a first end and a second end. Among them, the first end passes through the middle position at the bottom of the outer cover 110 and passes out from the depression 1101 and can communicate with the water outlet 132 on the rotating head 13, and the second end can communicate with the water inlet pipeline 2 of the intelligent toilet. The cover 11 with such a structure has a novel shape and a simple and reasonable structure. The first pipe 111 and the outer cover 110 in the cover 11 can be made of plastic and integrally formed by injection molding.

[0077] As Figures 5 to 8As shown, the rotating head 13 includes a frustum-shaped body 130 with a hollow interior and a circular tube body 140. A circular through-hole 131 is opened at the center of the upper bottom surface of the frustum-shaped body 130, and a water outlet 132 is opened on the lower bottom surface of the frustum-shaped body 130. A plurality of helical teeth with the same inclination angle as the side surface are provided on the side surface of the frustum-shaped body 130, and the above-mentioned helical teeth constitute a tooth portion 133 that meshes with the gear 122. The helical teeth constituting the tooth portion 133 can cover the entire side surface of the frustum-shaped body 130, or as shown in this embodiment, only a part of the side surface of the frustum-shaped body 130 is provided with helical teeth. The rotating head 13 rotates to align and communicate the water outlet 132 with different nozzles 20. Therefore, the layout of the helical teeth can be set according to the angle that the rotating head 13 needs to rotate.

[0078] The circular through-hole 131 and the water outlet 132 on the frustum-shaped body 130 are connected to the hollow cavity inside the frustum-shaped body 130, and the water outlet 132 is eccentrically arranged relative to the center of the lower bottom surface of the frustum-shaped body 130.

[0079] One end surface of the circular tube body 140 is attached to the upper bottom surface of the frustum-shaped body 130, and the circular tube body 140 is coaxially arranged with the frustum-shaped body 130. In this embodiment, the rotating head 13 is made of plastic, and the frustum-shaped body 130, the tooth portion 133, and the circular tube body 140 are integrally formed by injection molding.

[0080] In addition to the above structure, the rotating head 13 can also adopt a columnar or disc-shaped structure, as long as it can achieve gear transmission.

[0081] As Figure 1 shown, the first end of the first pipe 111 in the cover body 11 is inserted into the circular tube body 140 of the rotating head 13, and the circular tube body 140 and the frustum-shaped body 130 thereon can rotate on the first end of the first pipe 111. Preferably, a first sealing ring 10a sleeved on the first end is used to achieve a sealed connection between the inner peripheral surface of the circular tube body 140 and the outer peripheral surface of the first end of the first pipe 111.

[0082] The circular tube body 140 is in communication with the first pipe 111 at the first end, and the first pipe 111 is in communication with the water inlet pipe 2 of the intelligent toilet at the second end. The water enters from the circular tube body 140, then flows into the cavity of the frustum-shaped body 130 through the circular through-hole 131 of the frustum-shaped body 130, and finally sprays out from the water outlet 132.

[0083] As Figure 1 and Figure 9As shown, the drive mechanism 12 includes a motor 121 and a gear 122 that is drivingly connected to the motor 121. The gear 122 is preferably a bevel gear, so that it can mesh with the tooth portion 133 formed by helical teeth on the rotating head 13 to achieve power transmission between two perpendicularly intersecting axes. In addition to using the above-mentioned helical tooth transmission, spur gears with appropriate pitches and tooth portions 133 formed by straight teeth can also be selected to achieve power transmission between two intersecting axes. Additionally, a worm and worm gear can also be used to achieve the above functions.

[0084] The drive mechanism 12 further includes a transmission shaft 123 that is respectively drivingly connected to the motor 121 and the gear 122. One end of the transmission shaft 123 is coaxially and fixedly connected to the gear 122, and the other end is drivingly connected to the output end of the motor 121. By providing the transmission shaft 123, the torque output by the motor 121 can be efficiently and conveniently transmitted to the gear 122, and the placement position of the motor 121 can also be reasonably arranged. In this embodiment, the materials of the transmission shaft 123 and the gear 122 are both plastic, and the two are integrally formed and can be injection molded.

[0085] As Figure 1 shown, the commutator 10 further includes an electronic control board 14, and the motor 121 is control-connected to the electronic control board 14. By providing the electronic control board 14, the requirements for precisely controlling the speed, torque, etc. of the motor 121 can be met.

[0086] The motor 121 drives the gear 122 (bevel gear) to rotate through the transmission shaft 123. The tooth portion 133 (helical gear) on the rotating head 13 meshes with the gear 122, and the rotating head 13 rotates as the gear 122 rotates. The water outlet 132 on the rotating head 13 can rotate to a position corresponding to the feminine wash nozzle 21, the bidet nozzle 22, and the enema nozzle 23, and can be connected to the corresponding nozzle to enable the incoming water to be ejected from the nozzle for spraying and washing operations.

[0087] As Figure 1 and Figure 11 shown, the commutator 10 further includes a fixing seat 15 that is fastened to the cover body 11. Second pipes 151, 152, and 153 corresponding to the feminine wash nozzle 21, the bidet nozzle 22, and the enema nozzle 23 are respectively provided in the fixing seat 15, and each second pipe is connected to a nozzle. For example, the second pipe 151 is correspondingly connected to the feminine wash nozzle 21, the second pipe 152 is correspondingly connected to the bidet nozzle 22, and the second pipe 153 is correspondingly connected to the enema nozzle 23.

[0088] As Figure 10As shown, the fixed base 15 includes a main body 154 with a cuboid structure and a boss 155 provided on the main body 154. The bottom surface of the boss 155 is attached to the top surface of the main body 154. The three second pipes 151, 152, and 153 pass through the main body 154 and the boss 155 and then extend outside the boss 155, and the parts extending outside the boss 155 are connected together to form a pipe platform 156. The feminine wash nozzle 21, the bidet nozzle 22, and the enema nozzle 23 together with the base 24 are buckled on the boss 155 and the pipe platform 156.

[0089] The pipe platform 156 is provided with a first groove 1561, a second groove 1562, and a third groove 1563. Among them, the second groove 1562 communicates with the second pipe 152 corresponding to the bidet nozzle 22, the first groove 1561 communicates with the second pipe 151 corresponding to the feminine wash nozzle 21, and the third groove 1563 communicates with the second pipe 153 corresponding to the enema nozzle 23. The second groove 1562 is located between the first groove 1561 and the third groove 1563, and both the first groove 1561 and the third groove 1563 extend horizontally in a direction away from the second groove 1562. Before the incoming water enters different nozzles from the second pipes 151, 152, and 153 respectively, the first, second, and third grooves 1561, 1562, and 1563 play a role in guiding the flow. Moreover, the opening areas of the first, second, and third grooves 1561, 1562, and 1563 are larger, which is convenient for aligning and connecting with the nozzles, avoiding the influence on the water spraying effect of the nozzles due to misalignment.

[0090] As Figure 11 shown, a first concave cavity 1541 is provided at the lower part of the main body 154. The second pipes 151, 152, and 153 are communicated with the first concave cavity 1541, and the rotating head 13 is placed in the first concave cavity 1541.

[0091] As Figure 3 shown, the cover body 11 further includes three first threaded sleeves 112, and these three first threaded sleeves 112 are evenly arranged on the outer surface of the outer cover 110. As Figure 10 and Figure 11 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 tightly connected to the second threaded sleeve 1545, thereby realizing 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 realizes meshing with the rotating head 13 in the recess 1101 of the outer cover 110 and the first concave cavity 1541.

[0092] As Figure 1As shown, the outer cover 110 and the first cavity 1541 are hermetically connected through the second sealing ring 10b, and the transmission shaft 123 and the outer cover 110 and the first cavity 1541 are hermetically connected through the third sealing ring 10c.

[0093] As Figure 11 shown, the lower part of the body 154 is successively 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 electronic control board 14. The arrangement of these cavities provides a placement space for the transmission shaft 123, the motor 121, and the electronic control board 14 to play a protective role.

[0094] As Figure 1 and Figure 12 shown, the commutator 10 further includes a protective cover 16 that is buckled on the fixed seat 15 and surrounds the motor 121 and the electronic control board 14. The protective cover 16 includes a cover shell 161 and a plurality of clamping columns 162. Among them, the cover shell 161 is a square shell-like structure with a rectangular plate at the bottom, surrounded on all sides, and an open top. The cover shell 161 is fastened to the body 154 of the fixed seat 15, and the cover shell 161 and the fixed seat 15 are locked by means of bolt connection. The cover shell 161 and the body 154 of the fixed seat 15 are hermetically connected through a fifth sealing ring (not shown in the figure).

[0095] The transmission shaft 123, the motor 121, and the electronic control board 14 are placed between the cover shell 161 and the body 154. The transmission shaft 123 and the cover shell 161 and the body 154 are hermetically connected through the fourth sealing ring 10d. The clamping columns 162 are arranged in the cover shell 161, and the positions of the motor 121 and the electronic control board 14 are limited by the clamping columns 162 to prevent the motor 121 and the electronic control board 14 from shaking during operation and affecting the normal operation of the flushing system 1.

[0096] As Figure 14 shown, another embodiment of the present invention provides a nozzle for a smart toilet, including a housing 3 and the above-mentioned flushing system 1. The housing 3 is a pipe structure with a closed front end and an open rear end. The flushing system 1 is installed in the housing 3. The feminine wash nozzle 21, the posterior wash nozzle 22, the enema nozzle 23, and the base 24 in the flushing system 1 are fixed to the front end of the housing 3, and the feminine wash nozzle 21, the posterior wash nozzle 22, and the enema nozzle 23 extend outside the housing 3.

[0097] Another embodiment of the present invention provides a smart toilet, including a water inlet pipeline 2 and the above-mentioned nozzle.

[0098] After the above-mentioned flushing system 1 is assembled, the water inlet pipeline 2 is connected to the second end of the first pipeline 111 in the flushing system 1. Then, the flushing system 1 with the water inlet pipeline 2 is integrally installed in the housing 3. Finally, the nozzle is installed in the smart toilet, and the electronic control board 14 is connected to the smart toilet controller through a circuit.

[0099] The user can select any one of the three modes of feminine wash, bidet wash, and constipation relief wash through the buttons on the smart toilet. Taking the bidet wash as an example, the working process of the spray washing system 1 is described in detail as follows:

[0100] When the user selects the bidet wash mode through the button on the smart toilet, the smart toilet controller sends an electrical signal to the electronic control board 14. The electronic control board 14 controls the motor 121 to rotate. The motor 121 drives the transmission shaft 123 and the gear 122 to rotate. The rotating head 13 meshed with the gear 122 through the tooth part 133 rotates. The water outlet 132 on the rotating head 13 rotates to a position communicating with the second pipeline 152 in the fixed seat 15. At this time, the water inlet in the water inlet pipeline 2 enters from the round tube body 140 of the rotating head 13, then flows into the cavity of the frustum body 130 from the circular through hole 131 of the frustum body 130. Then the water inlet sprays out from the water outlet 132 into the second pipeline 152 and finally sprays out from the bidet wash nozzle 22 to clean the user.

[0101] The above only takes the bidet wash mode as an example. The working processes of the feminine wash and constipation relief wash modes are the same as that of the bidet wash mode and will not be elaborated here.

[0102] For the smart toilet, its spray washing system and nozzle provided in this embodiment, the rotating head 13 arranged close to 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 communicated with different nozzles 20. By realizing the water path switching at each nozzle 20, it not only reduces the usage amount of pipelines, makes reasonable use of space, but also shortens the distance for the water inlet to flow to the nozzle, avoids the accumulation of cold water, and improves the user experience.

[0103] Another embodiment, as Figure 15 and Figure 16 shown, the spray washing system 1 includes a commutator 10 and a plurality of nozzles 20. Among them, the commutator 10 includes a cover body 11, a sliding head 100, and an electromagnetic switch 101.

[0104] The cover body 11 has a first pipeline 111, and the first pipeline 111 can be communicated with the water inlet pipeline 2 of the smart toilet.

[0105] The sliding head 100 has a water outlet hole 1001, and the sliding head 100 is arranged close to the nozzle 20 and is slidably installed on the cover body 11.

[0106] The electromagnetic switch 101 preferably adopts a two-way electromagnetic switch. The electromagnetic switch 101 is drivingly connected to the sliding head 100. Driven by the electromagnetic switch 101, the sliding head 100 can slide on the cover body 11.

[0107] The sliding head 100 slides relative to the cover body 11, so that the water outlet hole 1001 slides to different nozzles and is communicated with the nozzles.

[0108] In the above-described spray washing system 1, the sliding head 100 disposed close to the nozzle 20 in the commutator 10 is slidably mounted on the cover body 11. As the sliding head 100 slides, the water outlet hole 1001 can communicate with different nozzles 20, realizing water path switching at each nozzle, reducing the amount of pipelines used, rationally utilizing the space, shortening the distance for the incoming water to flow to the nozzle, avoiding the accumulation of cold water, and improving the user experience.

[0109] In one embodiment, the commutator 10 further includes a connecting portion. The sliding head 100 is fixedly connected to the connecting portion. The electromagnetic switch 101 is drivingly connected to the sliding head 100 and the connecting portion. Driven by the electromagnetic switch 101, the connecting portion together with the sliding head 100 can slide on the cover body 11. The connecting portion not only supports the sliding head 100 but also guides the sliding of the sliding head 100 on the cover body 11.

[0110] As Figure 15 、 19 shown in 20, preferably, the connecting portion is a rod member 102 with a magnetic part. The front end of the rod member 102 is fixedly connected to the sliding head 100, and the rod member 102 can extend into the electromagnetic switch 101. The rod member 102 is a round rod, and a section away from the sliding head 100 is the magnetic part, and the rod member 102 extends into the electromagnetic switch 101. Under the action of the electromagnetic effect between the magnetic part and the electromagnetic switch 101, the electromagnetic switch 101 can drive the rod member 102 to drive the sliding head 100 to slide on the cover body 11. With the rod member 102, the magnetic part can be arranged on the rod member 102, so that it is convenient for the electromagnetic switch 101 to drive the sliding head 100.

[0111] In another embodiment, a diversion groove 1002 communicating with the water outlet hole 1001 is provided on the sliding head 100. The diversion groove 1002 faces the first pipeline 111 and can change the amount of water flowing from the first pipeline 111 to the water outlet hole 1001 as the sliding head 100 slides. The water outlet hole 1001 and the diversion groove 1002 can mix the water output, thereby realizing a soft water output effect.

[0112] In still another embodiment, the commutator 10 further includes a fixed seat 15. The cover body 11 and the fixed seat 15 are buckled with each other and are connected by bolts 17 therebetween. A cavity is formed between the fixed seat 15 and the cover body 11. The sliding head 100 and the rod member 102 are slidably arranged in the cavity. A plurality of nozzles 20 are installed on the fixed seat 15, and the fixed seat 15 has a second pipeline corresponding to and communicating with each nozzle 20. Driven by the electromagnetic switch 101, the rod member 102 together with the sliding head 100 can slide on the cover body 11. The sliding head 100 slides relative to the cover body 11, moving the water outlet hole 1001 to different second pipelines and communicating with the second pipelines.

[0113] As Figure 17 shown, multiple nozzles 20 include a feminine wash nozzle 21, a bidet nozzle 22, and a defecation nozzle 23. The above three nozzles 21, 22, and 23 are integrated on a base 24, thus saving space and optimizing the overall structure at the nozzle. The feminine wash nozzle 21, the bidet nozzle 22, and the defecation nozzle 23 are arranged in a straight line on the base 24 and have a certain interval between them to avoid interference during the water spraying operation and affect the user experience.

[0114] Second pipelines 151, 152, and 153 corresponding to the feminine wash nozzle 21, the bidet nozzle 22, and the defecation nozzle 23 are respectively provided in the fixing seat 15, and each second pipeline is communicated with a nozzle. For example, the second pipeline 151 is correspondingly communicated with the feminine wash nozzle 21, the second pipeline 152 is correspondingly communicated with the bidet nozzle 22, and the second pipeline 153 is correspondingly communicated with the defecation nozzle 23.

[0115] As Figure 21 and Figure 22 shown, the fixing seat 15 includes a boss 155, a pipeline platform 156, and a first housing 157. Among them, the bottom of the first housing 157 is a first recess 1571, the front side of the top is a flat top 1572, and the rear side of the top is an arc top 1573. The boss 155 is provided on the flat top 1572, and the bottom surface of the boss 155 fits with the top surface of the flat top 1572. The three second pipelines 151, 152, and 153 extend out from the part of the first recess 1571 facing the flat top 1572 and then extend outside the boss 155, and the parts extending outside the boss 155 are connected together to form the pipeline platform 156. The feminine wash nozzle 21, the bidet nozzle 22, and the defecation nozzle 23 together with the base 24 are buckled on the boss 155 and the pipeline platform 156.

[0116] First grooves 1561, second grooves 1562, and third grooves 1563 are provided on the pipeline platform 156. Among them, the second groove 1562 is communicated with the second pipeline 152 corresponding to the bidet nozzle 22, the first groove 1561 is communicated with the second pipeline 151 corresponding to the feminine wash nozzle 21, and the third groove 1563 is communicated with the second pipeline 153 corresponding to the defecation nozzle 23. The second groove 1562 is located between the first groove 1561 and the third groove 1563, and both the first groove 1561 and the third groove 1563 horizontally extend in a direction away from the second groove 1562. Before the water inlet enters different nozzles from the second pipelines 151, 152, and 153 respectively, the first, second, and third grooves 1561, 1562, and 1563 play a role in guiding the flow, and the opening areas of the first, second, and third grooves 1561, 1562, and 1563 are larger, which is convenient for aligning and communicating with the nozzles and avoids affecting the water spraying effect of the nozzles due to misalignment.

[0117] The above-mentioned fixed seat 15 can be made of plastic and integrally formed by injection molding.

[0118] As Figure 18 shown, the cover body 11 includes a first pipe 111 and a second housing 113. Among them, the top of the second housing 113 is a second recess 1131. The first pipe 111 is a right-angled elbow pipe, and its two ends are respectively a first end and a second end. The first end passes through the bottom of the cover body 11 and is connected to the first half of the second recess 1131, and the second end can be connected to the water inlet pipeline 2 of the intelligent toilet. The cover body 11 with such a structure has a novel shape and a simple and reasonable structure. The first pipe 111 and the second housing 113 in the cover body 11 can be made of plastic and integrally formed by injection molding.

[0119] As Figure 19 and Figure 20 shown, the sliding head 100 is a rounded rectangular block structure, and the water outlet hole 1001 is located in the middle of the sliding head 100 and penetrates the sliding head 100 in the thickness direction. The diversion groove 1002 is opened on the bottom surface of the sliding head 100, and the diversion groove 1002 is an oval groove extending inward from the bottom surface of the sliding head 100. The diversion groove 1002 is provided in the middle of the bottom surface of the sliding head 100, the diversion groove 1002 is connected to the water outlet hole 1001, and the diversion groove 1002 extends in the horizontal direction.

[0120] One end of the rod 102 is connected to the side surface of the sliding head 100. One section of the rod 102 away from the sliding head 100 is a magnetic section 1021. The sliding head 100 and the rod 102 can be made of plastic, and the two are connected into one body and integrally formed by injection molding.

[0121] In addition to adopting a rounded rectangular block structure, the sliding head 100 can also adopt a spherical or hemispherical structure to reduce wear. In addition, other suitable shape structures can also be used. The rod 102 can also adopt other suitable shape rods such as a square rod.

[0122] The sliding head 100 together with the rod 102 is arranged in the second recess 1131 of the cover body 11 in a slidable manner. The bottom surface of the sliding head 100 fits with the cavity bottom of the second recess 1131.

[0123] The fixed seat 15 is buckled on the cover body 11, and the two are connected and locked by bolts 17. The bolts 17 are evenly arranged around the cover body 11 and the fixed seat 15. Preferably, the fixed seat 15 and the cover body 11 are sealed by a sixth sealing ring 10e.

[0124] After assembly, the first concave portion 1571 in the cover body 11 and the fixed seat 15 is disposed opposite to the second concave portion 1131. The first concave portion 1571 and the second concave portion 1131 together form a cavity, and the sliding head 100 together with the rod member 102 can slide in the cavity.

[0125] As Figure 15 shown, the portion of the rod member 102 with the magnetic segment 1021 and the portions of the cover body 11 and the fixed seat 15 accommodating the rod member 102 are inserted into the electromagnetic switch 101. The electromagnetic switch 101 drives the rod member 102 to drive the sliding head 100 to slide in the cavity, and the sliding head 100 slides along the bottom of the second concave portion 1131. The extending direction of the diversion groove 1002 is the same as the sliding direction of the sliding head 100. The sliding head 100 slides relative to the cover body 11, so that the water outlet hole 1001 moves to the second pipes 151, 152, 153 and communicates with the corresponding second pipes. The diversion groove 1002 faces the first pipe 111 and can change the amount of water flowing from the first pipe 111 to the water outlet hole 1001 as the sliding head 100 slides. The water outlet hole 1001 and the diversion groove 1002 can mix the water outlet, so as to achieve a soft water outlet effect.

[0126] An embodiment, as Figure 15 shown, the sliding head 100 is located at the front of the cavity, the rod member 102 is located at the rear of the cavity, the rod member 102 together with the rear part of the cavity are placed in the electromagnetic switch 101, and a shoulder 1132 for limiting the stroke of the sliding head 100 is formed at the joint of the front and rear parts of the cavity. That is to say, the front and rear parts of the cavity are in the shape of a stepped hole, and the inner diameter of the front part of the cavity is larger than the inner diameter of the rear part of the cavity. In this way, a shoulder 1132 is formed at the joint of the front and rear parts of the cavity, so as to limit the sliding stroke of the sliding head 100 and the rod member 102, so that the water outlet hole 1001 can be quickly and accurately aligned with the second pipes 151, 152, 153 and the first pipe 111, reducing the water outlet waiting time and improving the user experience.

[0127] Another embodiment, the commutator 10 further includes an elastic member disposed in the cavity and telescoping with the sliding head 100 and the rod member 102.

[0128] As Figure 15 shown, the elastic member includes a first helical spring 103, and the first helical spring 103 is sleeved on the rod member 102 and abuts against the sliding head 100 and the shoulder 1132 respectively.

[0129] The elastic member further includes a second helical spring 104, and the second helical spring 104 abuts against the tail end of the rod member 102 and the inner wall of the cavity respectively.

[0130] When the sliding head 100 and the rod 102 compress the first helical spring 103 and the second helical spring 104 during sliding, the two helical springs 103 and 104 can buffer the sliding head 100 and the rod 102. Then, when the sliding head 100 and the rod 102 move in the opposite direction under the drive of the electromagnetic switch 101, the two helical springs 103 and 104 start to reset from the compressed state, thereby providing a thrust for the sliding of the sliding head 100 and the rod 102.

[0131] As Figure 23 shown, another embodiment of the present invention provides a nozzle for a smart toilet, including a housing 3 and the above-mentioned flushing system 1. The housing 3 is a tubular structure with a closed front end and an open rear end. The flushing system 1 is installed inside the housing 3. The feminine wash nozzle 21, the posterior wash nozzle 22, the enema nozzle 23 and the base 24 in the flushing system 1 are fixed at the front end of the housing 3, and the feminine wash nozzle 21, the posterior wash nozzle 22 and the enema nozzle 23 extend outside the housing 3.

[0132] Another embodiment of the present invention provides a smart toilet, including a water inlet pipeline 2 and the above-mentioned nozzle.

[0133] After the above-mentioned flushing system 1 is assembled, the water inlet pipeline 2 is connected to the second end of the first pipeline 111 in the flushing system 1. Then, the flushing system 1 with the water inlet pipeline 2 is integrally installed in the housing 3. Finally, the nozzle is installed in the smart toilet, and the electromagnetic switch 101 is connected to the smart toilet controller through a circuit.

[0134] The user can select any one of the three modes of feminine wash, posterior wash, and enema through the buttons on the smart toilet.

[0135] When the user selects the posterior wash mode through the button on the smart toilet, the smart toilet controller sends an electrical signal to the electromagnetic switch 101. At this time, one end of the water outlet hole 1001 on the sliding head 100 faces the first pipeline 111, and the other end of the water outlet hole 1001 faces the second pipeline 152 on the fixed seat 15. The water inlet in the water inlet pipeline 2 enters the diversion groove 1002 from the first pipeline 111. Then, the water inlet is sprayed into the second pipeline 152 through the water outlet hole 1001 and finally sprayed out from the posterior wash nozzle 22 to clean the user.

[0136] When the user selects the feminine wash mode through the button on the intelligent toilet, the intelligent toilet controller sends an electrical signal to the electromagnetic switch 101. The electromagnetic switch 101 drives the rod 102 to drive the sliding head 100 to slide in the cavity until the end of the water outlet hole 1001 is directly opposite the second pipe 151 on the fixed seat 15. At this time, the diversion groove 1002 is communicated with the first pipe 111, the water inlet enters the diversion groove 1002 from the first pipe 111, and then the water inlet is sprayed into the second pipe 151 through the water outlet hole 1001 and finally sprayed out from the feminine wash nozzle 21 to clean the user.

[0137] When the user selects the defecation mode through the button on the intelligent toilet, the intelligent toilet controller sends an electrical signal to the electromagnetic switch 101. The electromagnetic switch 101 drives the rod 102 to drive the sliding head 100 to slide in the cavity until the end of the water outlet hole 1001 is directly opposite the second pipe 153 on the fixed seat 15. At this time, the diversion groove 1002 is communicated with the first pipe 111, the water inlet enters the diversion groove 1002 from the first pipe 111, and then the water inlet is sprayed into the second pipe 153 through the water outlet hole 1001 and finally sprayed out from the defecation nozzle 23 to clean the user.

[0138] In addition, the intelligent toilet can also be set to other soft water outlet modes. The electromagnetic switch 101 is used to drive the sliding head 100 so that the diversion groove 1002 partially blocks the water outlet of the first pipe 111. In this way, the water output is reduced to achieve the purpose of soft water outlet. The settings of various soft water outlet modes can be set by setting the moving distance of the sliding head 100 to control the area of the diversion groove 1002 blocking the water outlet of the first pipe 111.

[0139] In the above-mentioned intelligent toilet, its spraying system and nozzle, the sliding head 100 arranged close to the nozzle 20 in the commutator 10 can be slidably installed on the cover body 11. As the sliding head 100 slides, the water outlet hole 1001 can be communicated with different nozzles 20, realizing waterway switching at each nozzle, which not only reduces the amount of pipes used, makes reasonable use of space, but also shortens the distance for the water inlet to flow to the nozzle, avoids cold water accumulation, and improves the user experience.
