Description

Technical Field

[0001] This invention relates to the field of bathroom technology, and in particular to a toilet seat with a cleaning device and a smart toilet. Background Technology

[0002] To meet people's pursuit of a healthy and comfortable life, traditional smart toilets (toilets) are equipped with various flushing functions. These functions, including piping and control systems, are typically housed within the toilet seat. The bidet function often uses a rear-mounted design, where the water flows from back to front, which doesn't conform to women's physiological structure. Furthermore, this flushing method, which goes against women's physiological structure, poses risks of cross-infection, poor comfort, and lower hygiene and safety. Therefore, the front-mounted bidet function was developed to meet the flushing needs of women's unique physiological structure and provide a better experience.

[0003] Currently available smart toilets on the market use a water-pressure pre-flush system. The principle is as follows: when the pre-flush function is active, water pressure forces the nozzle / spray head to extend from the seat body, reaching the user's front, side, or side-front position for a certain distance to clean. When the pre-flush function is stopped, water supply ceases, and the nozzle / spray head retracts into the seat body under spring pressure. This retractable nozzle design results in a fixed cleaning angle after extension, preventing flexible adjustment and failing to adapt to different users' physiological structures and actual cleaning needs. Users must constantly adjust their sitting posture to accommodate the cleaning position, leading to a poor user experience. Furthermore, this design results in a small cleaning range, significantly reducing the cleaning effect. Since the nozzle / spray head is propelled by water pressure, a separate water path is required for self-cleaning, making the water system relatively complex.

[0004] Therefore, in toilet seats and smart toilets, how to optimize the structural design of the pre-wash device, adjust the washing angle of the feminine wash function to meet the washing needs of different female users, and simplify the water outlet and self-cleaning water circuit settings of the feminine wash function pipeline has become one of the technical problems that technicians in this field urgently need to solve. Summary of the Invention

[0005] To address the shortcomings of the aforementioned prior art, this invention provides a toilet seat with a cleaning device and a smart toilet. The toilet seat with a cleaning device includes: a toilet seat body with a seat cavity at its front end; a water outlet located at the rear end of the seat cavity and on the inner sidewall of the front end of the toilet seat body; and a cleaning device disposed within the seat cavity, comprising a nozzle and a baffle. Along the water outlet direction of the nozzle, the baffle is disposed in the area in front of the nozzle, and the baffle is spatially offset from the water outlet direction of the nozzle. The baffle and the water outlet are opposite each other and can selectively block the water outlet, having a closed position and an open position. When in the closed position, the baffle blocks the water outlet; when in the open position, the baffle does not block the water outlet, and the water jet from the nozzle exits through the water outlet.

[0006] In some embodiments, the seat body includes at least an upper seat cover and a lower seat cover. After the upper seat cover and the lower seat cover are assembled and fixed, they form the seat cavity at the front end of the seat body. The water outlet is located on the lower seat cover.

[0007] In some embodiments, when the baffle is in the closed position, the water outlet direction of the nozzle is opposite to the upper inner wall of the seat cavity, and the water sprayed from the nozzle falls back towards the nozzle after being blocked by the upper inner wall.

[0008] In some embodiments, the seat ring with a cleaning device further includes a limiting member and a water inlet pipe, which are installed within the seat ring body. The limiting member is used to limit and fix the water inlet pipe. The limiting member includes a limiting through hole and mounting holes and wire through holes located on both sides of the limiting through hole, through which the water inlet pipe passes.

[0009] In some embodiments, the baffle may include: a baffle plate facing the water outlet door and having a size adapted to the water outlet door; a first guide channel and a second guide channel located on both sides of the baffle plate, the baffle plate protruding from the first guide channel and the second guide channel; and a plurality of third guide channels spaced apart above the baffle plate and respectively connected to the first guide channel and the second guide channel.

[0010] In some embodiments, the seat ring with the cleaning device further includes a drive mechanism located within the seat ring cavity and pivotally connected to the cleaning device. The drive mechanism drives the nozzle to swing vertically within the seat ring cavity via a pivotal engagement; the baffle is linked to the nozzle, and when the nozzle swings, it drives the baffle to swing synchronously, thereby selectively blocking the water outlet.

[0011] In some embodiments, when the gate is in the open position, the drive mechanism is configured to drive the nozzle of the cleaning device to reciprocate within a vertical tilt angle range of 0° to 30°.

[0012] In some embodiments, the cleaning device further includes a spray pipe and a cleaning bracket, the cleaning bracket having a receiving cavity, the spray pipe being disposed within the receiving cavity, and the nozzle being connected to the spray pipe.

[0013] In some embodiments, the cleaning bracket includes a mounting hole, and the driving mechanism is pivotally connected to the cleaning bracket through the mounting hole, driving the baffle and the nozzle to reciprocate in a vertical plane around the center line of the mounting hole. The cleaning bracket also includes a mounting shaft, with the mounting hole and the mounting shaft located on opposite sides of the receiving cavity. A mounting receiving component is provided inside the seat cavity, and the mounting shaft is fixedly connected to the mounting receiving component.

[0014] To achieve at least one or more of the aforementioned advantages, the present invention provides an intelligent toilet, the intelligent toilet comprising a toilet body and a seat ring, the seat ring being mounted on the toilet body, the seat ring being a seat ring with a cleaning device as described above, the cleaning device being a feminine wash device.

[0015] The present invention provides a toilet seat with a cleaning device and a smart toilet, which have at least the following advantages: 1. By selectively blocking the water outlet by using a barrier door set relative to the water outlet, the water flow from the nozzle is sprayed out through the water outlet when it is in the open position. This helps to simplify the internal structure of the device, reduce assembly difficulty and manufacturing costs.

[0016] 2. The cleaning angle of the nozzle can be adjusted during the cleaning process to avoid misalignment and adapt to the physiological structure of different users, further improving the user experience.

[0017] 3. During the cleaning process, the nozzle can swing up and down in a vertical plane to clean, covering a large area and creating an experience similar to "moving massage", which can further improve the cleaning effect and user experience.

[0018] 4. The water circuit for the nozzle self-cleaning and cleaning functions uses the same inlet pipe, which simplifies the water circuit and enables multi-functional control of a single water circuit. This simplifies the production and installation process, reduces production costs, and saves energy.

[0019] 5. The baffle structure at the water outlet area of ​​the seat body ensures a close fit with the water outlet, effectively preventing external urine and other contaminants from entering the seat cavity and contaminating the cleaning device, thus improving the cleanliness of the cleaning device and the cleaning experience. The baffle is positioned relative to the water outlet and can selectively block the water outlet, facilitating the switching and control of the nozzle self-cleaning and cleaning functions.

[0020] 6. During the self-cleaning process of the nozzle and the rinsing and cleaning of the perineal area from the front end, the nozzle is always located inside the seat cavity of the seat ring with the cleaning device. The nozzle will not extend outside the seat ring with the cleaning device. Compared with telescopic nozzles, this can reduce the contamination of the nozzle, thereby improving the cleanliness of the nozzle and the cleaning device. Attached Figure Description

[0028] Please see Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of an embodiment of the seat ring with a cleaning device according to the present invention. Figure 2 for Figure 1 The diagram shown is an exploded view of an embodiment of a seat ring with a cleaning device. Figure 3 for Figure 1 The diagram shows a three-dimensional structural representation of a toilet seat with the cleaning device installed. To achieve at least one or more of the aforementioned advantages, one embodiment of the present invention provides a toilet seat 1 with a cleaning device, which can be pivotally connected to the toilet body and has cleaning, heating, and sterilization functions. The toilet seat 1 with the cleaning device includes at least a toilet seat body 10 and a cleaning device 20, a drive mechanism 30, and a water inlet pipe 40 installed on the toilet seat body 10.

[0029] The seat body 10 has a front end 10a and a rear end 10b. In use, the front end 10a is closest to the user, and the rear end 10b is furthest from the user. The rear end 10b of the seat body 10 is pivotally connected to the toilet body and can rotate relative to the toilet body, so that the front end 10a can be closed or opened with the toilet body.

[0030] The seat body 10 includes an upper seat cover 12 and a lower seat cover 14. After the upper seat cover 12 and the lower seat cover 14 are assembled and fixed, a seat cavity 16 is formed at the front end 10a of the seat body 10, and the rear end 10b of the seat body 10 is pivotally connected to the toilet body. A water inlet pipe, a spray nozzle, electrical control circuitry, etc., can be installed within the space formed between the upper seat cover 12 and the lower seat cover 14. The upper seat cover 12 and the lower seat cover 14 can be assembled and fixed by welding, screws, or other methods. The shape of the seat cavity 16 can be regular or irregular, such as circular or square.

[0031] In some specific embodiments, such as Figure 2 As shown, the water inlet pipe 40 is installed on the inner side 120 of the seat ring upper cover and faces the seat ring lower cover 14. The water inlet end of the water inlet pipe 40 is located at the rear end 10b of the seat ring body 10 and is connected to the water supply source (such as a water inlet valve, reversing valve, or solenoid assembly) of the seat ring 1 equipped with a cleaning device. The water outlet end of the water inlet pipe 40 is located at the front end 10a of the seat ring body 10 and extends into the seat ring cavity 16 to connect with the cleaning device 20, thereby supplying water to the cleaning device 20 to achieve different cleaning functions.

[0032] To better secure the water inlet pipe 40 within the receiving space formed between the upper cover 12 and the lower cover 14 of the seat ring, the seat ring 1 with the cleaning device may also include a limiting member 50. The limiting member 50 is installed on the inner side 120 of the upper cover of the seat ring and is used to limit and secure the water inlet pipe 40. Figure 2 As shown, exemplarily, in some specific embodiments, the limiting member 50 may include a limiting through hole 51, a mounting hole 52, and a wire passage through hole 53. The limiting through hole 51, the mounting hole 52, and the wire passage through hole 53 may be integrally formed. There may be multiple limiting members 50, and the specific number can be determined according to the length of the water inlet pipe 40 within the seat cover 12.

[0033] Figure 2In the example, there are four limiting members 50. The outlet end of the water inlet pipe 40 passes sequentially through the limiting through holes 51 in each limiting member 50, and then connects to the cleaning device 20 within the seat cavity 16. In the example shown, the limiting through hole 51 is a rectangular through hole. The limiting through hole 51 can also be other shapes, such as circular, as long as it can accommodate the water inlet pipe 40. The mounting hole 52 and the wire passage hole 53 are located at both ends of the limiting through hole 51. The mounting hole 52 and the limiting through hole 51 can be arranged side by side. The limiting member 50 is mounted to the inner side 120 of the seat cover through the mounting hole 52. The limiting member 50 can be connected and fixed to the seat cover 12 through the mounting hole 52 by means of screw locking, snap connection, etc. The wire passage hole 53 allows the electrical wiring in the seat 1 with the cleaning device to pass through and be stored, thereby realizing the separation and storage of water and electricity lines. In the example shown, the through hole 53 is located below the limiting through hole 51, and the through hole 53 is open. With this configuration, after the limiting member 50 is fixed, the electrical wiring can be slid into the through hole 53 through the opening. In other specific embodiments, the limiting through hole 51, the mounting hole 52, and the through hole 53 can be arranged side-by-side on the same horizontal plane, with the water inlet pipe 40 and the electrical wire passing through the limiting through hole 51 and the through hole 53 respectively, and arranged parallel to each other in the horizontal direction.

[0034] A cleaning device 20 is installed inside the seat cavity 16. One end of the cleaning device 20 is connected to the outlet end of the water inlet pipe 40. The seat cavity 16 has a water outlet 160. The water outlet 160 is located at the rear end of the seat cavity 16 and on the inner wall 15 of the front end 10a of the seat body 10. The nozzle or spray outlet on the cleaning device 20 can spray water from the front end 10a to the rear end 10b of the seat body 10 through the water outlet 160 to clean the toilet or the user's body parts. The water outlet 160 can be located on the lower cover 14 of the seat. In the inner side 120 of the upper cover of the seat, the area of ​​the seat cavity 16 can be provided with a mounting support component 162, a receiving cavity 164, a mounting post 166, etc. The cleaning device 20 is fixedly connected to the mounting support component 162, and the drive mechanism 30 is installed in the receiving cavity 164 and connected to the cleaning device 20 through a pivot shaft. The drive mechanism 30 is mainly driven by a motor, which can be a stepper motor. The stepper motor can achieve angle subdivision control, thereby precisely controlling the swing angle of the cleaning device 20, thereby improving the cleaning range of the cleaning device 20 and the cleanliness of the human body, and improving the comfort experience.

[0035] After the cleaning device 20, drive mechanism 30, and water inlet pipe 40 are installed in the seat ring cavity 16, they need to be sealed and fixed to ensure effective isolation from external moisture and stable operation. The seat ring 1 with the cleaning device may also include a bottom cover 18, which covers the seat ring cavity 16. The bottom cover 18 can be installed and fixed to the seat ring cavity 16 by an assembly structure such as a mounting post 166. After installation and fixing, the exposed surface of the bottom cover 18 is flush with the inner surface of the lower cover 14 of the seat ring. A sealing element 17 is also provided between the bottom cover 18 and the seat ring cavity 16 to seal the inside of the seat ring cavity 16 and prevent external moisture from entering the seat ring cavity 16 through the gap between the bottom cover 18 and the seat ring cavity 16, thus affecting the stable operation of the cleaning device 20 and drive mechanism 30. The sealing element 17 can be a sealing strip that is adapted to the shape of the bottom cover 18. The clamping force after the bottom cover 18 is connected to the receiving cavity 164 can fix the drive mechanism 30 in the seat ring cavity 16, preventing the drive mechanism 30 from jumping during operation, thereby ensuring the stable operation of the motor in the drive mechanism 30.

[0036] Combination Figure 1 and Figure 2 See Figures 3 to 5 The cleaning device 20 can be installed in the seat cavity 16 via the mounting receiving component 162. The cleaning device 20 includes a nozzle 22, a spray pipe 24, and a cleaning bracket 26. The spray pipe 24 is provided with a nozzle mounting seat 242 and a mounting component 244. The water inlet end 240 of the spray pipe 24 is connected to the water outlet end of the water inlet pipe 40 to supply water to the nozzle 22. For example, the front end of the water inlet end 240 of the spray pipe 24 is arc-shaped, which can have a guiding function to facilitate connection and fixation with the water outlet end of the water inlet pipe 40. The nozzle mounting seat 242 is located at the water outlet end of the spray pipe 22. The nozzle 22 is installed on the nozzle mounting seat 242 and can be installed and fixed by welding, snap-fitting, screw locking, or other methods. The nozzle 22 can have multiple spray holes 220, through which the cleaning water in the spray pipe 240 can be sprayed out. In the example shown, along the water inlet 240 of the nozzle 24 towards the water outlet, the water outlet channel of the nozzle mounting base 242 is funnel-shaped, and the nozzle 220 in the nozzle 22 is a small cylinder and is set at an angle. This setting can increase the intensity of the water jet sprayed from the nozzle 220, thereby improving the cleaning effect and user experience.

[0037] The cleaning bracket 26 has a receiving cavity 260. A baffle 262 is provided at one end of the receiving cavity 260. The baffle 262 is located in the area in front of the water outlet direction of the nozzle 22 and on the side of the cleaning bracket 26 away from the water inlet pipe 40. The baffle 262 and the water outlet direction of the nozzle 22 are spatially misaligned. In the figure, the baffle 262 is located on the side of the water outlet end of the spray pipe 24. The baffle 262 and the water outlet direction of the nozzle 220 are spatially misaligned. That is, the baffle 262 does not obstruct the water flow from the nozzle 220 and the nozzle 20. A snap-fit ​​member 264 is provided on the outer side of the cleaning bracket 26. The mounting member 244 on the spray pipe 24 is snapped and fixed with the snap-fit ​​member 264, thereby mounting the spray pipe 24 on the cleaning bracket 26, and fixing the water inlet end 240 of the spray pipe 24 within the receiving cavity 260. After the cleaning device 20 is installed in the seat cavity 16, the spray pipe 24 and the water inlet pipe 40 are fixed within the mounting space enclosed by the seat cover 12 and the receiving cavity 260. The nozzle 22 is fixedly positioned above the baffle 262 and at an angle to the baffle 262. The angle between the nozzle 22 and the baffle 262 is acute, so that the spray hole 220 on the nozzle 22 is located obliquely above the baffle 262, and the water outlet direction of the spray hole 220 is spatially misaligned with the baffle 262. The nozzle 22 extends upward at an angle relative to the horizontal direction from its water inlet end to its water outlet end; that is, in the water outlet area of ​​the nozzle 22, the extension direction of the spray hole 220 is inclined upward at an angle relative to the horizontal direction.

[0038] The water outlet 160 is fixedly mounted on the lower cover 14 of the seat ring. A baffle 262 is located in the area of ​​the water outlet 160 within the seat ring cavity 16 and is movable relative to the water outlet 160, selectively blocking the water outlet 160. The baffle 262 has a closed position and an open position relative to the water outlet 160. When the baffle 262 is in the closed position, it blocks the water outlet 160. When the baffle 262 is in the open position, it does not block the water outlet 160.

[0039] The side of the baffle 262 away from the receiving cavity 260 may include a baffle 2620, a first guide channel 2622, a second guide channel 2624, and several third guide channels 2626. The baffle 2620 is sized to fit the outlet 160 and can prevent external contaminants from entering the seat cavity 16 through the area of ​​the outlet 160 corresponding to the baffle 2620 and contaminating the nozzle 22. The first guide channel 2622 and the second guide channel 2624 are located on both sides of the baffle 2620, and the baffle 2620 protrudes from the first guide channel 2622 and the second guide channel 2624. The two third guide channels 2626 are spaced apart and located above the baffle 2620, and are respectively connected to the first guide channel 2622 and the second guide channel 2624. Figure 4 and Figure 5As shown, two third guide channels 2626 are located above the baffle 2620 and are spaced apart from each other. The first guide channel 2622 and the second guide channel 2624 are located on both sides of the baffle 2620 and the two third guide channels 2626, respectively. This can be understood as follows: the main area of ​​the water outlet 160 is isolated and blocked from external contaminants by the baffle 2620; the area above the baffle 2620 is isolated from external contaminants by the third guide channels 2626; and the areas on both sides of the baffle 2620 are isolated from external contaminants by the first guide channels 2622 and the second guide channels 2624, respectively. This prevents external contaminants from entering the seat cavity 16 through the water outlet 160 and contaminating the nozzle 22.

[0040] A slot 2628 may be provided between the two third guide channels 2626. The cleaning bracket 26 also has a receiving groove 261, which is provided adjacent to the side of the baffle 262. After the nozzle 24 is fixed on the cleaning bracket 26, the nozzle mounting seat 242 is assembled and fixed with the receiving groove 261 on the cleaning bracket 26, and the nozzle 22 is installed in the slot 2628 and fixed relative to the baffle 262 within the area of ​​the slot 2628. In this way, the water outlet direction of the baffle 262 and the nozzle 22 are spatially misaligned. In the figure, the water outlet direction of the nozzle 22 is located above the baffle 262. It can be understood that when the drive mechanism 30 drives the cleaning bracket 26 to reciprocate, the baffle 262 fixed on the cleaning bracket 26 moves together with the nozzle 22, that is, the baffle 262 and the nozzle 22 reciprocate together in the vertical plane.

[0041] As shown in the figure, the nozzle 24 has an overall arc-shaped design. The water inlet 240 of the nozzle 24 is horizontal, while the water outlet is angled upwards. The mounting component 244 is located in the arc-shaped bend of the nozzle 24, and the nozzle mounting seat 242 is located at the water outlet of the nozzle 24. Thus, when the mounting component 244 is engaged and fixed with the cleaning bracket 26, the nozzle 24 can be fixed within the receiving cavity 260 of the cleaning bracket 26. At the same time, the nozzle mounting seat 242 is engaged and fixed with the receiving groove 261 on the cleaning bracket 26, thereby securing the nozzle 22 in the slot 2628 area of ​​the baffle 262.

[0042] In the example shown, when the baffle 262 is in the closed position, the baffle 262 blocks the water outlet 160. The first guide channel 2622, the second guide channel 2624 and the third guide channel 2626 can guide and block urine, debris and other substances located on the baffle 262 in the area of ​​the water outlet 160, and guide them into the body of the toilet and be flushed away by the washing water.

[0043] The cleaning bracket 26 may also include a mounting hole 266 and a mounting shaft 268, located on both sides of the receiving cavity 260. The mounting shaft 268 is fixedly connected to the mounting receiving component 162 within the seat cavity 16 area. The drive mechanism 30 is pivotally connected to the cleaning device 20 through the mounting hole 266 to drive the nozzle 22 to reciprocate vertically for cleaning and rinsing. In some specific embodiments, the mounting hole 266 can be a pivot shaft. The mounting hole 266 can be a stepped cylindrical hole with a sealing element 2660 for sealing connection with the drive mechanism 30. The mounting receiving component 162 within the seat cavity 16 area includes notched ribs or support plates for receiving the mounting shaft 268 and clamping it with the bottom cover 18, thereby ensuring the stability of the cleaning device 20 after it is fixedly installed.

[0044] The drive mechanism 30 drives the nozzle 22 to swing vertically within the seat cavity 16 via a pivotal connection (such as mounting hole 266). Simultaneously, the baffle 262 is linked to the nozzle 22; when the nozzle 22 swings, it drives the baffle 262 to swing synchronously, allowing the baffle 262 to selectively block the water outlet 160. When the baffle 262 is in the open position, the drive mechanism 30 is configured to drive the nozzle 22 of the cleaning device 20 to reciprocate within a vertical tilt angle range of 0° to 30°. That is, when the drive mechanism 30 drives the cleaning bracket 26 to swing, the baffle 262 and the nozzle 22 reciprocate within a vertical tilt angle range of 0° to 30°.

[0045] As shown in the figure, the nozzle 22 is mounted on the nozzle 24 and located in front of the nozzle 24 in the water outlet direction. The nozzle 24 is fixed to the cleaning bracket 26. The drive mechanism 30 is pivotally connected to the cleaning bracket 26 through the mounting hole 266 (such as a pivot shaft). When the baffle 262 is in the open position, the drive mechanism 30 drives the cleaning bracket 26 to reciprocate around the center line of the mounting hole 266 in the vertical plane. The cleaning bracket 26 then drives the baffle 262 to reciprocate, thereby driving the baffle 262 and the nozzle 22 to reciprocate around the center line of the mounting hole 266 in the vertical plane. Furthermore, in the vertical plane, the swing angle of the baffle 262 and the nozzle 22 is 0° to 30°.

[0046] Combination Figures 3 to 5 See Figure 1After the cleaning device 20, drive mechanism 30, and inlet pipe 40 are installed and fixed in the seat cavity 16, the two ends of the outlet 160 abut against the side ends of the first guide groove 2622 and the second guide groove 2624 on the baffle 262, respectively. This creates a staggered embedding effect between the seat body 10 and the baffle 262, effectively preventing urine and other liquids from splashing into the seat cavity 16 and contaminating the nozzle 22. At this time, no special retaining mechanism is needed between the outlet 160 and the baffle 262, simplifying the structure and making installation convenient.

[0047] Please combine Figures 1 to 5 See Figures 6 to 9 The working cycle of the seat ring 1 with the cleaning device in this invention will be described. To achieve at least one or more of the aforementioned advantages, one embodiment of the present invention provides an intelligent toilet 2, which may include a toilet body 60 and the aforementioned seat ring 1 with the cleaning device, the seat ring 1 with the cleaning device being mounted on the toilet body 60. The toilet body 60 is made of ceramic material. The seat ring 1 with the cleaning device is mounted on the toilet body 60 via the rear end 10b of the seat ring body 10, and can be flipped relative to the toilet body 60. The intelligent toilet 2 may also include a toilet seat cover 3. The toilet seat cover 3 is located above the seat ring 1 with the cleaning device, can be connected to the rear end 10b of the seat ring body 10, and can be flipped relative to the seat ring 1 with the cleaning device. The intelligent toilet 2 has a pre-wash function, in which case the cleaning device 20 is a feminine wash device.

[0048] See Figure 6 When the smart toilet 2 is in standby mode, the seat ring 1 with the cleaning device is in its initial state, and the cleaning device 20 does not dispense water. The baffle 262 is in a closed position relative to the water outlet 160, and the baffle 262 in the cleaning device 20 blocks the water outlet 160 of the seat ring cavity 16, while the nozzle 22 is stationary. At this time, the cleaning device 20 is not working, and the nozzle 22 does not dispense water.

[0049] See Figure 7The nozzle 22 enters its first self-cleaning state. The baffle 262 in the cleaning device 20 is in a closed position relative to the water outlet 160, completely blocking the water outlet 160 of the seat cavity 16. The nozzle 22 and the baffle 262 are fixed in place within the seat cavity 16, meaning the nozzle 22 does not reciprocate. Inside the seat cavity 16, the front end of the nozzle 22 in the water outlet direction (shown as the upper inner wall area of ​​the seat cavity 16 in the diagram) is in a semi-enclosed, narrow space. Within this narrow space, the water outlet direction of the nozzle 22 is positioned opposite to the upper inner wall of the seat cavity 16. The nozzle 22 sprays water towards this narrow space, and the sprayed water forms the first self-cleaning water column 70. After being blocked by the upper inner wall of the seat cavity 16, the first self-cleaning water column 70 falls back towards the nozzle 22 under the action of gravity, thereby performing the first self-cleaning cleaning of the nozzle 22. This allows the nozzle 22 to be cleaned before entering the feminine wash state, ensuring the cleanliness of the nozzle 22 surface during the feminine wash state.

[0050] See Figure 8 After the first self-cleaning cycle of the nozzle 22 in the seat ring 1 with the cleaning device ends, the nozzle 22 stops dispensing water. The baffle 262 in the cleaning device 20, driven by the drive mechanism 30, opens the water outlet 160 of the seat ring cavity 16, and the nozzle 22 rotates to a set angle to begin spraying water. With the baffle 262 in the open position relative to the water outlet 160, the drive mechanism 30 drives the nozzle 22 to oscillate vertically within a certain angle range, spraying a cleaning water column 80 towards the rear end 10b of the seat ring body 10 through the water outlet 160. This achieves the cleaning of the female user's private parts from the front of the smart toilet 2 (seat ring 1 with the cleaning device), realizing the pre-wash function. The nozzle 22, within its vertical oscillation angle range, can clean the private parts of different female users from different angles, thus meeting the physiological needs of different female users and realizing the pre-wash function. During the feminine wash process, the reciprocating motion of the nozzle 22 in the vertical direction increases the washing area, thus creating a "moving massage" experience, further improving the washing effect and user experience.

[0051] by Figure 7 and Figure 8 For example, in the structural appearance of the seat ring 1 with a cleaning device, in some specific embodiments, it is assumed that when the baffle 262 is in a closed position relative to the water outlet 160, the cleaning spray angle of the nozzle 22 is 0°, that is, 0° when the cleaning device 20 is not swinging. Figure 7 .like Figure 8Driven by the drive mechanism 30, the drive cleaning device 20 swings vertically within the seat cavity 16. During the downward vertical rotation of the cleaning device 20 and nozzle 22, the maximum opening angle is 21°, which can be understood as the maximum opening angle of the baffle 262 and nozzle 22 being 21°. In the feminine wash cleaning state, the effective cleaning angle of the vertical reciprocating swing of the nozzle 22 driven by the drive mechanism 30 is 16° to 19°. The nozzle 22 reciprocates within this effective cleaning angle range, and the rotation direction of the nozzle 22 is as follows... Figure 8 As indicated by the rotating arrow, this allows for back-and-forth washing of the perineal area, providing a massage-like experience. It can be understood that during the feminine wash, the effective washing angle of the nozzle 22 is 75%-90% of its maximum opening angle. In some specific embodiments, the maximum opening angle between the baffle 262 and the nozzle 22 is 30°. During the feminine wash, the effective washing angle of the nozzle 22, the maximum opening angle of the nozzle 22, and the relationship between the two are closely related to the structural appearance of the seat ring 1 with the washing device.

[0052] In addition, driven by the drive mechanism 30, the cleaning water jet 80 sprayed from the nozzle 22 can also be positioned and cleaned at a certain angle to clean the female user's private parts, realizing the pre-washing function.

[0053] See Figure 9 When the smart toilet 2 (seat ring 1 with a cleaning device) receives a command to end the feminine wash or a command to pause during the feminine wash process, the seat ring 1 with the cleaning device transitions from the feminine wash state to the second self-cleaning state of the spray head 22. The baffle 262 in the cleaning device 20, driven by the drive mechanism 30, selectively blocks the water outlet 160 of the seat ring cavity 16. With the baffle 262 in a closed position relative to the water outlet 160, the spray head 22 sprays water inside the seat ring cavity 16.

[0054] Within the seat cavity 16, the front end of the nozzle 22 (shown as the upper inner wall area of ​​the seat cavity 16 in the diagram) is situated in a semi-enclosed, narrow space. Within this narrow space, the nozzle 22's water outlet direction is positioned opposite to the upper inner wall of the seat cavity 16. The nozzle 22 sprays water towards this narrow space, forming a second self-cleaning water column 90. After being blocked by the upper inner wall of the seat cavity 16, the second self-cleaning water column 90 falls back towards the nozzle 22 primarily under gravity, thus performing a second self-cleaning of the nozzle 22 to ensure the cleanliness of its surface after the feminine wash. After the second self-cleaning of the nozzle 22 is completed, the seat 1 with the cleaning device returns to its original position. Figure 6The initial state shown constitutes a complete working cycle of the seat ring 1 with the cleaning device. In one overall working cycle, the self-cleaning process of the nozzle 22 and the feminine wash process share a single water inlet pipe 40, realizing multi-functional control of a single water path, simplifying the pipeline structure and production and installation process, and saving water resources and other energy consumption.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
