Description

Technical Field

[0001] The present invention relates to the technical field of smart toilets, and in particular to a spray rod structure and a smart toilet. Background Art

[0002] In modern home life, smart toilets are increasingly becoming an important choice for people pursuing a high-quality lifestyle due to their convenience and comfort. The use of a spray bar structure to achieve buttocks cleaning in smart toilets has become a core requirement for improving user health and comfort.

[0003] In the prior art, the spray rod cleaning assembly of a smart toilet generally has two types of flushing nozzles: detachable and non-detachable. However, no matter which of the above methods is used, the spray rod will inevitably come into contact with water containing dirt during the process of flushing the human body or self-cleaning the nozzle. Although some designs use self-cleaning water to flush the spray rod, it is still difficult to completely remove the dirt or unclean water remaining on the surface of the spray rod. When the spray rod is retracted to the base after cleaning or use, the dirt and sewage remaining on its surface will be brought into the base. After long-term use, it is easy to cause rust, mildew, and odor inside the base, affecting the service life and sanitary performance of the product.

[0004] It should be noted that the information disclosed in this background technology section is only intended to increase understanding of the overall background of the present invention, and should not be regarded as an admission or any form of implication that the information constitutes prior art already known to those skilled in the art.

[0021] Example 1 See also Figures 1 to 5 The present invention provides a spray boom structure, which at least includes a base 10, a spray boom assembly 20, and a sealing assembly 30.

[0022] The base 10 serves as the mounting base for the overall structure and has an inner cavity 11 therein for accommodating at least the spray boom assembly 20. The shape of the inner cavity 11 should be appropriately configured based on the actual spray boom assembly 20 and other required components that may be included. Furthermore, the shape of the inner cavity 11 should be compatible with the motion trajectory of the spray boom assembly 20. A passage 12 is defined on the sidewall of the base 10, connecting the inner cavity 11 with the outside. This passage 12 provides space for the extension and retraction of the spray boom assembly 20, and its specific shape can be appropriately configured based on actual needs.

[0023] The spray bar assembly 20 is the core component for achieving the cleaning function. It is capable of telescopic movement along the channel 12 and includes a mounting end 20a and an extension end 20b. The mounting end 20a is located at the rear end of the spray bar assembly 20 and is primarily used to connect to the drive mechanism (e.g., motor, screw assembly, etc.) and the water system (e.g., water inlet pipe, control valve, etc.) within the inner cavity 11 of the base 10. Driven by the drive mechanism, the spray bar assembly 20 can be extended or retracted along the channel 12. Controlled by the water system, the extension end 20b can spray water for human body cleansing, self-cleaning, or cleaning other components (e.g., internal descaling wastewater, disinfectant, high-temperature steam, etc.).

[0024] The extension end 20b is located at the front end of the spray bar assembly 20. It is equipped with at least one nozzle (such as a posterior wash nozzle, a feminine wash nozzle, a descaling nozzle, a disinfecting nozzle, etc.) for directly spraying the corresponding medium. When not in operation, the extension end 20b is completely retracted into the front cavity 12a of the channel 12. When in operation (such as when performing a flushing function), the extension end 20b extends outward from the channel 12 to the exterior of the base 10 to complete the corresponding operation.

[0025] See also Figure 3 The sealing assembly 30 is a key structure for achieving isolated cleaning. It is positioned between the channel 12 and the boom assembly 20, separating the channel 12 into a mutually independent front cavity 12a and rear cavity 12b. The sealing assembly 30 is preferably an elastic seal (such as a rubber sealing ring, silicone sealing sleeve, etc.), with its inner side tightly contacting the outer circumference of the boom assembly 20 (interference fit) and its outer side fixedly connected to the inner wall of the channel 12 (e.g., by snap-fit, adhesive, or threaded connection). The cross-sectional shape of the sealing assembly 30 can be designed based on the shapes of the channel 12 and the boom assembly 20 (e.g., a circular sealing ring, a special-shaped sealing ring, etc.), ensuring that the seal is maintained during the extension and retraction of the boom assembly 20.

[0026] Please continue reading Figure 3In this embodiment, the sealing assembly 30 is preferably an annular silicone ring. The inner side of the annular silicone ring forms an interference fit with the boom assembly 20. This interference fit allows the inner sidewall of the annular silicone ring to tightly adhere to the outer circumferential wall of the boom assembly 20. During extension and retraction of the boom assembly 20, the seal between the two is maintained, effectively preventing sewage and dirt from the front cavity 12a from entering the rear cavity 12b and the inner cavity 11 of the base 10. In particular, during retraction of the boom assembly 20, liquid on the outer wall of the boom assembly 20 is effectively scraped away by the annular silicone ring, preventing it from entering the rear cavity 12b. The annular silicone ring has an annular groove 30a defined along its circumference. The frame 13 is disposed within the channel 12, and the annular groove 30a engages with the frame 13. The cross-sectional shape and dimensions of the annular groove 30a are designed based on the structure of the frame 13 and are typically rectangular or trapezoidal. The frame 13 within the channel 12 provides a stable mounting base for the annular silicone ring, and the shape of the frame 13 matches the outer edge of the annular silicone ring. During installation, the annular groove 30a of the annular silicone ring is embedded in the frame 13, that is, the frame 13 is embedded in the annular groove 30a. Through the close fit between the annular groove 30a and the frame 13, the annular silicone ring is firmly fixed in the channel 12 to prevent it from being displaced or falling off during the movement of the spray rod assembly 20, thereby ensuring the position stability of the sealing assembly 30.

[0027] In an alternative embodiment, the sealing assembly 30 includes two sealing members correspondingly arranged along the upper and lower directions of the spray boom assembly 20, and the two sealing members are configured so that when the spray boom assembly 20 is in a retracted state, the two sealing members are in contact with the outer wall of the spray boom assembly 20 to form a wrap, so as to scrape off the liquid on the outer wall of the spray boom assembly 20; when the spray boom assembly 20 is not in a retracted state, the two sealing members are separated from the spray boom assembly 20.

[0028] In practice, this embodiment achieves a directional wiping function when the boom assembly 20 is retracted through the coordinated action of two seals, while also preventing ineffective contact when not in operation. The surface of the seal on the side closest to the boom assembly 20 is a mating surface that mates with the outer wall of the boom assembly 20. The edges of the mating surface are rounded, ensuring a tight fit while preventing scratches on the boom surface. The two seals are removably mounted at corresponding upper and lower positions on the inner wall of the channel 12. When the boom assembly 20 is retracted, the mating surfaces of the two seals tightly mate with the outer wall of the boom assembly 20, forming a wraparound or fully annular structure. At this point, any liquid remaining on the surface of the boom assembly 20, including residual wastewater after flushing and accumulated water during the cleaning process, is completely scraped away by the mating surfaces. The scraped liquid flows along the seal surface to the sloped surface of the front cavity 12a, ultimately draining out through the drainage hole. This design ensures that no liquid remains on the surface of the spray bar assembly 20 during the retraction process, thereby blocking the path for sewage to pollute the inner cavity 11 of the base 10 from the source.

[0029] When the boom assembly 20 is not in the retracted state, including when it is being extended, in operation, or in a partially extended paused state, the two seals remain separated from the boom assembly 20. Specifically, a corresponding mechanical linkage structure (such as a cam structure, a bidirectional screw structure, a multi-link structure, etc.) or an electromagnetic control structure can be used to achieve the relative approach or separation of the two seals.

[0030] Through the above arrangement, the wiper effect is formed by contacting with the seal only when the spray rod assembly 20 is retracted, and the seal remains separated from the spray rod assembly 20 in other states, which can effectively reduce the wear of the seal caused by unnecessary contact and extend the service life of the seal.

[0031] See also Figure 3 、 Figure 4 、 Figure 5 The front cavity 12a is the channel 12 area on the side of the sealing assembly 30 close to the outside of the base 10. The extended end 20b of the spray rod assembly 20 is retracted into this area as a whole when not in operation, and the extended end 20b always passes through the front cavity 12a during the extension / retraction process; the rear cavity 12b is the channel 12 area on the side of the sealing assembly 30 close to the inner cavity 11 of the base 10. The mounting end 20a and part of the main body of the spray rod assembly 20 are located in this area, and the rear cavity 12b is directly connected to the inner cavity 11 of the base 10.

[0032] Due to the isolation effect of the sealing assembly 30, there is no fluid communication between the front cavity 12a and the rear cavity 12b. In other words, sewage and dirt that may remain in the front cavity 12a cannot enter the rear cavity 12b and the inner cavity 11 of the base 10, thereby preventing the interior of the base 10 from being contaminated.

[0033] Furthermore, in the non-operating state, the boom assembly 20 is completely retracted, with the extended end 20b completely located within the front cavity 12a, and the nozzle is not exposed. The sealing assembly 30 tightly fits the boom assembly 20, strictly isolating the front cavity 12a from the rear cavity 12b. In the operating state, the drive mechanism drives the boom assembly 20 forward along the channel 12, and the extended end 20b extends from the channel 12 to the outside of the base 10, and the nozzle sprays water to perform a flushing operation.

[0034] When the extended end 20b of the spray bar assembly 20 needs to be cleaned (e.g., when the self-cleaning function is activated or manual cleaning is required), the extended end 20b can be partially or completely retracted into the front cavity 12a (without entering the rear cavity 12b). The extended end 20b within the front cavity 12a can then be cleaned using an external cleaning device (e.g., a dedicated cleaning brush or a self-cleaning nozzle built into the front cavity 12a). Due to the isolation effect of the sealing assembly 30, wastewater generated during cleaning remains only within the front cavity 12a and can be discharged directly into the toilet bowl 51 through a drain hole (not shown) or drain channel 12 or outlet provided at the bottom of the front cavity 12a, without entering the rear cavity 12b or the inner cavity 11 of the base 10.

[0035] It should be understood that during the extension or retraction of the extended end 20b, in one embodiment, the sealing assembly 30 may elastically deform (or slide relative to) the boom assembly 20 in sync with the movement, maintaining the sealed separation between the front cavity 12a and the rear cavity 12b. In another embodiment, the sealing assembly 30 is stationary, with only the extended end 20b located in the front cavity 12a moving. The specific configuration can be appropriately adjusted based on actual needs and is not limited in this embodiment.

[0036] This embodiment achieves physical isolation between the extended end 20b of the boom assembly 20 and the mounting end 20a and the inner cavity 11 of the base 10 through the design of the sealing assembly 30. This allows the extended end 20b of the boom assembly 20 to retract only into the front cavity 12a when not in operation. Any residual sewage or dirt on its surface is confined within the front cavity 12a and prevented from entering the rear cavity 12b and the inner cavity 11 of the base 10. This fundamentally prevents rust, mildew, or odor from forming within the base 10. Furthermore, the sealing assembly 30 effectively scrapes liquid from the outer wall of the boom assembly 20 when the boom assembly 20 is retracted, further ensuring the hygiene and cleanliness of the rear cavity 12b and the inner cavity 11 of the base 10. In addition, when cleaning the spray rod assembly 20, it is only necessary to operate the protruding end 20b in the front cavity 12a (there is no need to pull the spray rod assembly 20 completely out of the base 10 or extend it into the rear cavity 12b). The operation is more convenient, and the clean sewage can be discharged directly to avoid secondary pollution.

[0037] Preferably, in order to effectively drain the accumulated water in the front cavity 12a and avoid the residual sewage causing bacterial growth or component corrosion, please continue to refer to Figure 3 、 Figure 6 The bottom surface of the front cavity 12a, which is close to the spray bar assembly 20, is defined as the bottom surface 121a. The bottom surface 121a is a sloped surface that slopes from the direction close to the rear cavity 12b to the side away from the rear cavity 12b. The angle of inclination can be set according to the depth and space size of the front cavity 12a, usually between 5° and 15°. This ensures that the accumulated water flows smoothly under the action of gravity, while not affecting the utilization rate of the internal space of the front cavity 12a due to excessive inclination. In the actual structure, the bottom surface 121a of the front cavity 12a smoothly transitions with the inner wall of the channel 12, forming a continuous slope. When the spray bar assembly 20 generates sewage during the cleaning process, or when the spray bar assembly 20 retracts into the front cavity 12a, water dripping from the surface will naturally flow to the bottom surface 121a of the front cavity 12a. Since the bottom surface 121a is a sloped surface, the accumulated water will flow along the inclined direction toward the side away from the rear cavity 12b, and can eventually be discharged into the toilet bowl 51 through the drainage hole set at the lowest point of the front cavity 12a, or directly discharged from the gap between the flip cover 102b and the cover plate 10b, or the gap when the spray rod assembly 20 is extended.

[0038] By designing the bottom surface 121a as a sloped surface, not only can gravity be used to accelerate the discharge of accumulated water in the front cavity 12a, avoiding sewage from remaining on the bottom surface 121a for a long time, and reducing the possibility of mold growth and odor generation due to accumulated water; it also makes the sloped surface less likely to accumulate dirt than a flat surface. Even if a small amount of dirt is attached, it will be discharged along with the accumulated water under the flushing of the water flow, which helps to keep the bottom of the front cavity 12a clean.

[0039] Optionally, see Figure 6 The spray bar structure also includes a drying component 40, which is located in the base 10, and the drying component 40 is provided with an air outlet 40a at a position facing the front cavity 12a to dry the front cavity 12a and the spray bar component 20 located in the front cavity 12a.

[0040] In a specific implementation, the drying assembly 40 can be used to dry the buttocks after washing them with the spray bar assembly 20. Alternatively, the drying assembly 40 can be used to dry the self-cleaning spray bar assembly 20. The specific design should be tailored to actual needs and is not limited in this embodiment.

[0041] The drying assembly 40 comprises a heating unit (not shown), an air supply unit, and an air duct structure. The heating unit, which can be a PTC heater or heating wire, heats the air to a suitable temperature (typically 40-60°C, balancing drying efficiency and user comfort). The air supply unit, which can be a miniature axial flow fan or centrifugal fan, provides a stable airflow. The air duct structure connects the heating unit and the air supply unit at one end, and forms an air outlet 40a at the other end. This air outlet 40a is primarily directed toward the user's buttocks, ensuring efficient drying of the buttocks.

[0042] From the installation position, the drying assembly 40 is fixed to the side of the base 10 near the extension direction of the spray rod assembly 20. Its air duct layout should give priority to the airflow path for drying the buttocks. At the same time, according to the actual structural design, for example, through the branch structure or diversion design of the air duct, part of the airflow of the drying assembly 40 can be directed to the front cavity 12a. Specifically, a branch air duct can be set on the main air duct path (leading to the buttocks area), and the air outlet 40a of the branch air duct is connected to the front cavity 12a. Figure 6 As shown, or by adjusting the angle of the air outlet 40a, part of the hot air can be diffused into the front cavity 12a while blowing toward the buttocks; the air outlet 40a of the drying component 40 can also be set at a position close to the front cavity 12a of the channel 12, so that when the hot air is blown toward the buttocks, part of the air flow can naturally flow into the front cavity 12a.

[0043] During operation, after the user has finished washing their buttocks, drying assembly 40 activates, primarily performing a buttocks drying function: the air supply unit draws in air, which is heated by the heating unit to form hot air. This hot air then flows through the main air duct and is blown toward the user's buttocks from air outlet 40a, quickly removing moisture and improving user comfort. During this process, according to the aforementioned practical structure, some of the hot air will enter the front cavity 12a, coming into contact with the extended end 20b of the spray bar assembly 20 and the inner wall of the front cavity 12a. Through heat exchange, this air removes any residual moisture from the surface of the spray bar assembly 20 and within the front cavity 12a, thereby drying the spray bar assembly 20. The moisture-laden air can be discharged through a gap connecting the front cavity 12a to the outside world or through a specially designed exhaust hole.

[0044] The drying assembly 40 primarily meets the user's core need for drying their buttocks, enhancing ease of use and comfort. Furthermore, thanks to its rational structural design, it simultaneously dries the spray bar assembly 20 while achieving its primary function. This further reduces residual moisture on the surface of the spray bar assembly 20 and within the front cavity 12a, lowering the risk of mold growth and keeping the spray bar assembly 20 cleaner and drier. The drying process can be automatically triggered by the controller in conjunction with the rinsing function, eliminating the need for additional user interaction.

[0045] Furthermore, to enhance the cleaning effect of the spray boom assembly 20 and ensure the cleanliness of the front cavity 12a and the spray boom assembly 20, the spray boom structure also includes a cleaning assembly, which includes a water outlet pipe. One end of the water outlet pipe is connected to a water source (such as a tap water pipe or a clean water source in a toilet tank), and the other end is connected to a water outlet structure for spraying cleaning water into the spray boom assembly 20. A control valve can be installed on the water outlet pipe to control the on / off flow and flow rate of the cleaning water, ensuring controllable cleaning process.

[0046] In one embodiment, the sealing assembly 30 defines a water outlet hole 13a connected to the water outlet pipe, allowing the cleaning assembly to clean the spray boom assembly 20 located in the front cavity 12a through the water outlet hole 13a. The sealing assembly 30 itself functions to block the gap between the passage 12 and the spray boom assembly 20, while the water outlet hole 13a also provides a water outlet path for the cleaning assembly. The position of the water outlet hole 13a can be designed based on the position of the spray boom assembly 20 in the front cavity 12a when not in operation, typically toward the extended end 20b of the spray boom assembly 20. When the spray boom assembly 20 needs to be cleaned, the control valve is opened, and water is delivered through the water outlet pipe to the water outlet hole 13a of the sealing assembly 30. Water is then ejected from the water outlet hole 13a to form a cleaning water flow, which directly acts on the surface of the spray boom assembly 20 located in the front cavity 12a, flushing it and removing any residual dirt and sewage. Due to the isolation effect of the sealing assembly 30 , the wastewater generated by cleaning is limited to the front cavity 12 a and will not enter the rear cavity 12 b and the inner cavity 11 of the base 10 .

[0047] In another embodiment, see Figure 5 、 Figure 6A frame 13 is formed within the channel 12, and the sealing assembly 30 is nested within the frame 13. The frame 13 is provided with a water outlet hole 13a that communicates with the water outlet pipe, allowing the cleaning assembly to clean the spray boom assembly 20 located in the front cavity 12a through the water outlet hole 13a. The frame 13 provides a stable mounting base for the sealing assembly 30, enabling it to more securely seal the gap between the channel 12 and the spray boom assembly 20. The water outlet hole 13a on the frame 13 is connected to the water outlet pipe and can be positioned around the periphery of the spray boom assembly 20 when not in operation, thereby achieving all-round flushing of the spray boom assembly 20. When the cleaning function is activated, cleaning water flows through the water outlet pipe to the water outlet hole 13a of the frame 13, and after being sprayed out of the water outlet hole 13a, it flushes the spray boom assembly 20 located in the front cavity 12a. With this design, the frame 13 not only serves to mount the sealing assembly 30 but also provides a reasonable water outlet path for the cleaning assembly through the water outlet hole 13a, allowing the cleaning water to be more evenly applied to the surface of the spray bar assembly 20, thereby improving the cleaning effect. In this embodiment, the water outlet hole 13a is preferably located above the spray bar assembly 20. The water outlet hole 13a can be designed as a nozzle capable of spraying a predetermined distance according to actual needs.

[0048] Of course, the two aforementioned embodiments can also be used in combination, i.e., the sealing assembly 30 is provided with a water outlet hole 13a, while the frame 13 within the channel 12 is also provided with a water outlet hole 13a, both of which are connected to the water outlet pipe. During cleaning, the two types of water outlet holes 13a simultaneously spray cleaning water, flushing the spray boom assembly 20 from different angles, further enhancing the cleaning effect and ensuring the cleanliness of the spray boom assembly 20. This embodiment utilizes a cleaning assembly to make cleaning of the spray bar assembly 20 more proactive and efficient, eliminating the need to rely on the spray bar assembly's 20 self-cleaning water flow and enabling targeted removal of residual dirt from the spray bar assembly 20 during use. Furthermore, the cleaning process is performed solely within the front cavity 12a, effectively preventing contamination of the inner cavity 11 of the base 10 by wastewater from cleaning. This, in conjunction with the sealing assembly 30 and drying assembly 40, ensures the hygienic performance of the spray bar assembly 20 and the entire device, providing users with a cleaner and more hygienic experience.

[0049] Optionally, see Figure 2 、 Figure 7The base 10 comprises a base 10a and a cover 10b. The base 10a serves as the main support portion of the base 10 and defines an inner cavity 11 for accommodating the boom assembly 20, the drive mechanism, and various functional modules. A channel 12 is provided on the front wall of the base 10a, providing a path for the telescopic movement of the boom assembly 20. The cover 10b detachably covers the top or front surface of the base 10a. It not only protects the internal components of the base 10a from direct intrusion of external dust and moisture, but also forms the outer contour of the base 10 by cooperating with the base 10a, enhancing the product's aesthetics.

[0050] Please continue reading Figure 7 The cover plate 10b defines a slot 101b at a location corresponding to the front cavity 12a. The shape and dimensions of this slot 101b are designed based on the contours of the front cavity 12a and the position of the extended end 20b of the spray bar assembly 20 when not in operation. Typically, it is elongated or circular, ensuring that the slot 101b fully exposes the core area of ​​the front cavity 12a and the extended end 20b of the spray bar assembly 20. The edges of the slot 101b are rounded to prevent scratches from sharp corners and enhance tactile comfort.

[0051] A flap 102b is movably connected to the slot 101b. The flap 102b is sized to fit the slot 101b and can completely cover the slot 101b, thereby sealing the front cavity 12a. The flap 102b can be opened to expose the front cavity 12a and the extended end 20b of the spray bar assembly 20. The flap 102b can be connected to the cover plate 10b using a hinge, a pivot, or an elastic hinge. When a hinge or pivot connection is used, the flap 102b can be rotated within a range of 0-90° around the connecting axis, ensuring that the slot 101b is fully exposed when opened. When an elastic hinge connection is used, the flap 102b can remain closed in its natural state, open under external force, and automatically return to its original position when released, enhancing ease of operation. The outer surface of the flap 102b can be flush with the outer surface of the cover plate 10b, giving the base 10 a more unified and coordinated overall appearance.

[0052] During actual use, when the user needs to manually clean the extended end 20b of the spray boom assembly 20 or observe the interior of the front cavity 12a, they can simply flip open the flip cover 102b to directly expose the front cavity 12a and the extended end 20b of the spray boom assembly 20 located therein through the slot 101b. The user can then use a cleaning tool to wipe or rinse the spray boom assembly 20. After cleaning is complete, closing the flip cover 102b reseals the slot 101b, preventing external dirt from entering the front cavity 12a and ensuring that the spray boom assembly 20 is clean and tidy.

[0053] The advantages of this structural design are: on the one hand, the setting of the flip cover 102b ensures the sealing of the front cavity 12a in the non-clean state, preventing dust and debris from entering the front cavity 12a through the slot 101b and contaminating the spray bar assembly 20; on the other hand, direct operation can be performed by flipping open the flip cover 102b, without the need to remove the cover 10b or perform complicated electronic control operations, which significantly improves the convenience of manual cleaning and is particularly suitable for scenarios where users perform deep cleaning or emergency treatment of the spray bar assembly 20.

[0054] Furthermore, in order to achieve smooth extension of the spray bar assembly 20 in the working state and ensure the sealing of the front cavity 12a in the non-working state, please refer to Figure 8 A through opening 103b is provided on the surface of the flip cover 102b, and a baffle 104b is movably connected to the through opening 103b. When in operation, the protruding end 20b of the spray rod assembly 20 extends from the front cavity 12a and pushes open the baffle 104b to be exposed outside the cover 10b.

[0055] In specific implementations, the through-opening 103b is located in the middle of the flip cover 102b or at a position corresponding to the motion trajectory of the extended end 20b of the spray boom assembly 20 in the operating state. Its shape matches the cross-section of the extended end 20b of the spray boom assembly 20, ensuring smooth passage of the extended end 20b of the spray boom assembly 20. A smooth transition is employed at the junction between the edge of the through-opening 103b and the flip cover 102b to reduce frictional resistance during extension of the spray boom assembly 20. The baffle 104b is movably connected to the through-opening 103b to completely cover the through-opening 103b in the non-operating state, achieving a sealed enclosure. The baffle 104b can be connected to the flip cover 102b by a hinge, an elastic connection, or a pin connection, among other methods.

[0056] During operation, when the spray boom assembly 20 needs to be extended, the extended end 20b of the spray boom assembly 20 extends from the front cavity 12a and continues forward until it contacts the baffle 104b at the through-opening 103b of the flip cover 102b. As the spray boom assembly 20 continues to extend, its extended end 20b applies a thrust to the baffle 104b, causing the baffle 104b to open due to its own gravity or elastic force. The extended end 20b of the spray boom assembly 20 is then able to pass through the through-opening 103b and be exposed outside the cover 10b, thereby performing tasks such as flushing. When the work is completed, the extended end 20b of the spray boom assembly 20 retracts rearward, and the baffle 104b automatically closes due to its own gravity, elastic force, or other reset mechanism, re-covering the through-opening 103b, isolating the front cavity 12a from the outside world and preventing dust, dirt, etc. from entering the front cavity 12a.

[0057] Through this design, on the one hand, baffle 104b can effectively block through-opening 103b when not in operation, and together with flip cover 102b, ensure the sealing of front cavity 12a, further preventing the ingress of external contaminants. On the other hand, when in operation, boom assembly 20 can automatically extend to push open baffle 104b, eliminating the need for an additional drive mechanism to control the opening of baffle 104b. This simplifies the structural design and reduces costs. Furthermore, this design allows for smoother extension and retraction of boom assembly 20, without affecting its normal operation, and improves the overall coordination and reliability of the device.

[0058] In a preferred embodiment, the spray rod assembly 20 is connected to one of the disinfection module (not shown in the figure), the sterilization module (not shown in the figure), the descaling module (not shown in the figure) or the breech washing module, or the spray rod assembly 20 is connected and switched with multiple modules among the disinfection module, the sterilization module, the descaling module or the breech washing module through a reversing valve structure (not shown in the figure).

[0059] The spray rod assembly 20 is the core executive component for realizing functions such as flushing, cleaning, and disinfection. It can integrate multiple functions through selective connection with different functional modules to meet the user's diverse needs for toilet use and spray rod maintenance itself.

[0060] Specifically, the spray bar assembly 20 can be directly connected to any of the following modules: the disinfection module, the sterilization module, the descaling module, or the buttocks washing module. In this case, the spray bar assembly 20 can specifically implement the functions of the corresponding module. For example, when the spray bar assembly 20 is only connected to the buttocks washing module, the flushing water delivered by the buttocks washing module can be directly sprayed out through the nozzle of the spray bar assembly 20 to achieve the buttocks washing function for the human body; if the spray bar assembly 20 is only connected to the disinfection module, the disinfection medium (such as disinfectant, high-temperature steam, etc.) generated by the disinfection module can be exported through the spray bar assembly 20 to disinfect the spray bar assembly 20 itself or a designated area. This single module connection method can make the spray bar assembly 20 more concise in structure and is suitable for scenarios with relatively simple functional requirements.

[0061] The spray boom assembly 20 also uses a reversing valve structure to selectively connect and switch with various modules, including the disinfection module, sterilization module, descaling module, and diaper wash module, thus enabling the spray boom assembly 20 to switch between multiple functions. The reversing valve serves as a switching hub for media flow, with its input connected to each functional module and its output connected to the spray boom assembly 20. When a function is required, the reversing valve switches to the communication channel 12 of the corresponding module, allowing the medium in that module to smoothly enter the spray boom assembly 20 and act on the target object through the nozzle. In specific implementation, taking the example of the spray rod assembly 20 being connected to the hip washing module, the disinfection module, and the descaling module through a reversing valve, when the user needs hip washing, the reversing valve switches to the state where the hip washing module is connected to the spray rod assembly 20, and the water of suitable temperature and pressure provided by the hip washing module flows through the spray rod assembly 20 and is sprayed out to complete the hip washing operation; when the spray rod assembly 20 needs to be disinfected, the reversing valve switches to the state where the disinfection module is connected to the spray rod assembly 20, and the disinfection medium generated by the disinfection module circulates through the spray rod assembly 20 to disinfect the inside of the spray rod assembly 20 and the nozzle to avoid bacterial growth; and when scale accumulates in the spray rod assembly 20 or the inside of the toilet and needs to be cleaned, the reversing valve switches to the state where the descaling module is connected to the spray rod assembly 20, and the descaling agent or specific water of the descaling module flows through the spray rod assembly 20 to realize the descaling function. Furthermore, the spray bar assembly 20 can be equipped with multiple nozzles with different functions, each corresponding to a different module. By switching the reversing valve, the media of different modules are sprayed from different nozzles, improving the accuracy of functional implementation. For example, the water flow of the posterior washing module is sprayed from the posterior washing nozzle, and the media of the disinfection module is sprayed from the disinfection nozzle, avoiding functional interference caused by the mixing of different media within the spray bar assembly 20.

[0062] Through the above-mentioned connection method, the spray rod assembly 20 can flexibly realize the switching of multiple functions without the need to set up multiple independent execution components, simplifying the overall structure. At the same time, it meets the user's various needs for cleaning, hygiene maintenance, etc. during the use of the toilet, and improves the practicality of the product and user experience.

[0063] Example 2 The present invention also provides an intelligent toilet, comprising the spray rod structure described in any one of the implementation modes in the above-mentioned embodiment 1.

[0064] In practice, the spray bar structure is installed within the smart toilet to perform cleaning functions. The spray bar structure also communicates with the smart toilet via signals, effectively improving cleaning effectiveness and satisfying the cleaning experience of various users. It also effectively prevents sewage and dirt from entering the inner cavity 11 of the base 10, reducing rust, mildew, and odor, significantly improving the internal sanitation of the toilet. Furthermore, this structure is simple and easy to install, without adding too many complex components. This improves user safety and convenience, meeting user demands for high-quality, high-cleanliness smart toilets.

[0065] Preferably, see Figure 1 The smart toilet also includes a seat 50, which serves as the main support structure for the user to sit on. The base 10 is mounted on the rear side of the seat 50, forming an integral part of the seat 50. In this embodiment, the base 10 is preferably formed as part of the seat 50 to ensure the overall structural strength and stability of the smart toilet.

[0066] The front side of the base 50 includes a toilet bowl 51. When not in operation, the extended end 20b of the spray bar assembly 20, located within the front cavity 12a, is elevated above the upper surface of the toilet bowl 51. Specifically, this design prevents the extended end 20b of the spray bar assembly 20 from coming into direct contact with dirt or sewage within the basin when not in operation, reducing the risk of contamination and further ensuring the cleanliness of the spray bar assembly 20. Furthermore, when the basin is flushed, the extended end 20b, which is elevated above the basin's upper surface, is not directly impacted by the flushing water, minimizing interference with the extended end 20b and the potential for dirt to adhere to it.
