Description

Technical Field

[0001] This disclosure relates to, but is not limited to, kitchen and bathroom technologies, and in particular to a spray bar mechanism and a toilet. Background Technology

[0002] Current toilets typically feature a bidet sprayer for washing the body and / or a foam sprayer that creates a foam shield. When the bidet extends from the toilet bowl, liquids and dirt from the environment can easily adhere to it, posing a risk of contamination. Therefore, the bidet is cleaned by a cleaning unit before and after use. This cleaning process usually takes place inside the toilet bowl. For example, after the lid, which conceals the bidet's mounting location, is closed, the cleaning unit washes the bidet. However, the cleaning fluid can easily flush dirt from the bidet onto the lid, causing secondary contamination. Over time, this can lead to bacterial growth and negatively impact user experience. Summary of the Invention

[0012] In some embodiments of the spray bar mechanism, the guide channel has a first end away from the spray bar and a second end close to the spray bar, and the width of the guide channel gradually decreases from the first end to the second end.

[0013] In some embodiments of the spray bar mechanism, the cover plate facing the recovery position also has a first stop portion, which protrudes from the guide surface on the side away from the spray bar.

[0014] In some embodiments of the spray bar mechanism, second stop portions are respectively provided on the two sides opposite to the first stop portion, and the second stop portions extend from the first stop portion along the circumferential outer edge of the guide surface.

[0015] In some embodiments of the spray bar mechanism, the pivot axis on which the cover plate rotates relative to the toilet seat and the movement path of the spray bar are arranged vertically along the direction of gravity, and the cleaning fluid generated by the cleaning assembly can drive the cover plate to rotate around the pivot axis away from the spray bar.

[0016] In some embodiments of the spray bar mechanism, the cover plate includes a cover body and a flow guide platform disposed on the side of the cover body facing the recycling position. The flow guide platform protrudes outward from the cover body, and the flow guide surface is disposed on the side of the flow guide platform facing the recycling position.

[0017] In some embodiments of the spray bar mechanism, the guide platform includes a connecting portion and a raised portion. The connecting portion is disposed on the cover, and the raised portion is disposed on the side of the connecting portion facing the spray bar and inclined away from the cover, and a notch facing the spray bar is formed between the raised portion and the cover.

[0018] In some embodiments of the spray bar mechanism, the thickness of the connecting portion gradually increases from the side away from the spray bar to the side closer to the spray bar, wherein the thickness is the dimension of the connecting portion in the direction perpendicular to the cover.

[0019] In some embodiments of the spray bar mechanism, the cover includes a first connecting plate and a second connecting plate. The first connecting plate is rotatably connected to the toilet seat. The second connecting plate is disposed on the side of the first connecting plate near the spray bar and is inclined from the first connecting plate toward the retraction position. The connecting part is disposed on the first connecting plate and the second connecting plate.

[0020] In some embodiments of the spray bar mechanism, the toilet seat is provided with a first limiting member and a second limiting member, the second limiting member being able to rotate with the seat to abut against the first limiting member, thereby limiting the rotation angle of the seat relative to the toilet seat.

[0021] In some embodiments of the spray bar mechanism, at least one of the first limiting member and the second limiting member has an elastic portion, which can elastically abut against the other through the elastic portion, thereby improving the limiting fit between the first limiting member and the second limiting member.

The seat is configured to cover the spray boom in the retracted position and can rotate relative to the toilet seat to avoid movement of the spray boom relative to the mounting base. The cleaning assembly is configured to generate cleaning fluid sprayed towards the side of the seat facing the retracted position, so that the cleaning fluid is guided to the spray boom by the stop action of the seat. This design allows the cleaning fluid to be guided through the cover plate to the spray bar for cleaning. During the cleaning process, the cleaning fluid passes through the cleaning components, the cover plate, and the spray bar sequentially, preventing the cleaning fluid from washing away dirt on the spray bar onto the cover plate and causing secondary pollution. Furthermore, the cleaning fluid continuously rinses the cover plate during the cleaning process, preventing splashes of dirt from contaminating the cover plate.

[0029] Other features and advantages of this disclosure will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the disclosure.

[0044] The realization of the purpose, functional features and advantages of this disclosure will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] Existing toilets typically include a bidet sprayer for washing the body and / or a foam sprayer that creates a foam shield effect. When the bidet extends from the toilet bowl, liquids and dirt from the environment can easily adhere to it, posing a risk of contamination. Therefore, the bidet is cleaned by a cleaning unit before and after use. This cleaning process usually takes place inside the toilet bowl. For example, after the lid 40, which conceals the bidet's mounting location, is closed, the cleaning unit cleans the bidet. At this time, the cleaning fluid can easily wash dirt from the bidet onto the lid 40, causing secondary contamination. Over time, this can lead to bacterial growth and negatively impact user experience.

[0046] This disclosure provides a toilet that can be installed in various environments such as companies, schools, homes, and factories. The toilet can be, but is not limited to, wall-mounted or seat-mounted smart toilets.

[0047] Please combine them together Figures 1 to 3 The toilet provided in this embodiment will now be described. The toilet includes a toilet body 10, a toilet seat 60, and a spray mechanism. The toilet seat 60 is mounted on the toilet body 10. The toilet body 10 may be made of ceramic material, or the outer wall of the toilet body 10 may have a ceramic coating to facilitate cleaning and improve stain resistance. The toilet body 10 has a basin 11 that can enclose and form a basin cavity 100. The basin 11 has a drain outlet 200 to discharge waste from the toilet body 10. The spray mechanism may be a cleaning spray for washing the human body and / or a foam spray that can produce a foam shield effect, etc. For ease of description of this embodiment, a cleaning spray is used as an example below.

[0048] Please combine them together Figure 2 , Figure 4a , Figure 4b and Figure 5 The spray boom mechanism includes a mounting base 20, a spray boom 30, a toilet seat 60, and a cleaning assembly 50. The mounting base 20 is mounted on the toilet seat 60. The spray boom 30 is movably mounted on the mounting base 20 and can move relative to the mounting base 20 between an extended position and a retracted position. The mounting base 20 is located at the upper rear end of the toilet seat 60. In this embodiment, the mounting base 20 is mounted to the toilet body 10 via the toilet seat 60, and the spray boom 30 can extend from the toilet seat 60 to an extended position located within the pelvic cavity 100. The spray boom 30 can retract to a retracted position located within the toilet seat 60.

[0049] The toilet seat 40 is rotatably connected to the toilet seat 60. The toilet seat 40 is configured to conceal the spray nozzle 30 in the retracted position. The toilet seat 40 cooperates with the toilet body 10 and / or the toilet seat 60 to hide the spray nozzle 30 in the retracted position, so that the spray nozzle 30 is not visible when not in use, making the toilet more aesthetically pleasing. Furthermore, it prevents dirt from sticking to the mounting base 20 and the spray nozzle 30 in the retracted position.

[0050] The toilet seat 40 is rotatable relative to the toilet seat 60 to avoid the movement of the spray bar 30 relative to the mounting base 20. A cleaning assembly 50 is mounted on the mounting base 20 and is configured to generate cleaning fluid that sprays onto the side of the toilet seat 40 facing the recycling position. This cleaning fluid is guided to the spray bar 30 by the stop action of the toilet seat 40, thereby cleaning the spray bar 30. The rotation of the toilet seat 40 relative to the toilet seat 60 can be driven by the spray bar 30 or by the cleaning fluid. The cleaning fluid can be pre-stored in a reservoir installed in the toilet body 10. In some embodiments, the toilet body 10 may also be equipped with a storage tank that can store solid or liquid cleaning media. The storage tank can be connected between the cleaning assembly 50 and the municipal water network. When the cleaning assembly 50 is activated, clean water from the municipal water network can enter the storage tank, carrying the cleaning media into the cleaning assembly 50. The clean water mixes with the cleaning media to form a cleaning fluid, which is then sprayed out from the cleaning assembly 50.

[0051] When the human body washing function is activated, the spray bar 30 moves from the retracted position to the extended position. For ease of washing, the extended position is generally located diagonally below the retracted position within the basin 100 and a distance from the opening of the basin 100, ensuring that the movement path and extension direction of the spray bar 30 are both inclined downwards. Simultaneously, the washing assembly 50 opens, and the toilet seat 40 rotates relative to the toilet seat 60 and moves away from the movement path of the spray bar 30 under the influence of the washing fluid. The washing fluid is guided to the spray bar 30 by the stopping action of the toilet seat 40, thus washing the spray bar 30. The washing fluid passing through the spray bar 30 falls directly into the basin 100. The washing fluid, after being sprayed onto the toilet seat 40, forms a large-area liquid flow due to the stopping action of the toilet seat 40, achieving an efficient pre-wetting and anti-sticking effect on the spray bar 30.

[0052] During the human body washing process, the washing component 50 can be continuously turned on or off.

[0053] After the user wash is completed, the washing component 50 is in the open state (the washing component 50 can remain open during the user wash process; or it can be reopened after the user wash is completed). Driven by the cleaning fluid, the toilet seat 40 rotates relative to the toilet seat 60 and moves away from the path of the spray bar 30. The cleaning fluid is guided to the spray bar 30 by the stop action of the toilet seat 40, and cleans the spray bar 30. The cleaning fluid passing through the spray bar 30 falls directly into the basin cavity 100. The cleaning fluid sprayed onto the toilet seat 40 forms a large-area liquid flow due to the stop action of the toilet seat 40, achieving a highly efficient cleaning effect on the spray bar 30. The cleaning of the spray bar 30 takes place on the outside of the toilet seat 40, and the resulting wastewater flows directly into the basin cavity 100, ensuring the cleanliness and hygiene of the inside of the toilet seat 40, the mounting base 20, and the installation location of the spray bar 30, thus improving the user experience.

[0054] When the hydraulic pressure of the cleaning fluid is high, the cover plate 40 can rotate relative to the toilet seat 60 under the drive of the cleaning fluid, and a gap is formed between the cover plate 40 and the spray bar 30, so that the cleaning fluid can flow on the spray bar 30 through the gap and increase the cleaning area of ​​the cleaning fluid on the spray bar 30.

[0055] When the hydraulic pressure of the cleaning fluid is low, the lid 40 cannot separate from the spray bar 30 after rotating relative to the toilet seat 60 under the drive of the cleaning fluid. At this time, the movement path of the lid 40 away from the spray bar 30 still needs to be driven by the spray bar 30. Although the contact between the lid 40 and the spray bar 30 affects the flow of the cleaning fluid relative to the spray bar 30, the cleaning assembly 50 is always open during the movement of the spray bar 30 relative to the mounting base 20 between the extended position and the retracted position, ensuring the cleaning effect on the spray bar 30.

[0056] Please combine them together Figure 4a , Figure 4b and Figure 5The cleaning assembly 50 includes an inlet pipe 51 and a nozzle 52. The inlet pipe 51 communicates with the nozzle 52, allowing cleaning fluid to be introduced into the nozzle 52. The nozzle 52 is mounted on the mounting base 20 and sprays the cleaning fluid onto the cover plate 40. The nozzle 52 and the inlet pipe 51 can be detachably connected or integrally formed, or they can be joined together by a tight fit or ultrasonic welding. In this embodiment, the cleaning assembly 50 also includes a mounting member 53. The nozzle 52 can be mounted on the mounting base 20 via the mounting member 53. The nozzle 52 and the mounting member 53 can be detachably connected or integrally formed, or they can be joined together by a tight fit or ultrasonic welding.

[0057] In this embodiment, the nozzle 52 has a tubular structure, which is simple and easy to manufacture. The nozzle 52 can adjust the position of the cleaning fluid acting on the cover plate 40 by changing the installation angle between it and the mounting member 53 or by changing the installation angle between the mounting member 53 and the mounting base 20. The installation position of the mounting member 53 and the mounting base 20 can match the outer wall of the mounting base 20 to improve the connection stability between them. The mounting member 53 and the mounting base 20 can be detachably connected or integrally formed, or they can be joined together by tight fit or ultrasonic welding.

[0058] In summary, implementing the embodiments of this disclosure will have the following beneficial effects: The spray bar mechanism described above, when applied to a toilet, not only provides better human body cleaning and / or foam spraying effects, but also prevents the cleaning fluid from washing away dirt on the spray bar 30 towards the toilet seat 40 during the cleaning process, thus avoiding secondary pollution. Specifically, the spray bar mechanism includes a mounting base 20 mounted on the toilet seat 60, a spray bar 30 movably mounted on the mounting base 20, a seat 40 rotatably connected to the toilet seat 60, and a cleaning assembly 50 mounted on the mounting base 20. The spray bar 30 can move relative to the mounting base 20 between an extended position and a retracted position to perform human body cleaning and / or foam spraying and to achieve the function of storing the spray bar 30. The seat 40 is configured to cover the spray bar 30 in the retracted position and can rotate relative to the toilet seat 60 to avoid movement of the spray bar 30 relative to the mounting base 20. The cleaning assembly 50 is configured to generate cleaning fluid that is sprayed onto the side of the cover plate 40 facing the recycling position, so that the cleaning fluid is guided to the spray bar 30 by the stop action of the cover plate 40. This allows the cleaning fluid to pass through the cover plate 40 and be guided to the spray bar 30 for cleaning. During the cleaning process of the spray bar 30, the cleaning fluid passes sequentially through the cleaning assembly 50, the cover plate 40, and the spray bar 30, preventing the cleaning fluid from washing away dirt on the spray bar 30 and causing secondary pollution to the cover plate 40. Furthermore, during the cleaning process of the spray bar 30, the cleaning fluid continuously rinses the cover plate 40, preventing splashed dirt from contaminating the cover plate 40.

[0059] In the exemplary embodiment, please combine with Figure 4a , Figure 4b and Figures 6 to 10 The cover plate 40 has a guide surface 41 on the side facing the recycling position, and the nozzle 52 can apply the cleaning fluid to the guide surface 41. The guide surface 41 bends towards the spray bar 30, which can guide the cleaning fluid generated by the cleaning assembly 50 to the spray bar 30. In this way, the guide surface 41 can guide the cleaning fluid to the spray bar 30, so that the cleaning fluid acting on the cover plate 40 can be guided to the spray bar 30 in a certain direction.

[0060] In this embodiment, the guide surface 41 is arc-shaped, allowing the cleaning fluid to change direction more gently after contacting the guide surface 41, thus reducing the amount of splashing generated by the cleaning fluid acting on the guide surface 41. The bending amplitude of the guide surface 41 gradually increases from the side away from the spray bar 30 to the side closer to the spray bar 30. It can be understood that in other embodiments, the guide surface 41 may also be planar, and by being inclined to the spray direction of the cleaning fluid, it guides the cleaning fluid to the spray bar 30.

[0061] In the exemplary embodiment, please combine with Figures 7 to 10 At least one flow guide groove 300 is provided on the flow guide surface 41, and the flow guide groove 300 extends towards the spray bar 30. In this way, the flow guide groove 300 can further limit the flow direction of the cleaning fluid on the cover plate 40, improve the directional accuracy of the cover plate 40 in guiding the cleaning fluid, and ensure that most of the cleaning fluid can be guided to the spray bar 30 under the stopping action of the cover plate 40, so as to ensure that there is a sufficient amount of cleaning fluid to clean the spray bar 30.

[0062] In this embodiment, the extension direction of the guide channel 300 is perpendicular to the rotation axis 42 of the cover plate 40. It can be understood that in other embodiments, the extension direction of the guide channel 300 may also be non-perpendicular to the rotation axis 42 of the cover plate 40, as long as the guide channel 300 extends towards the spray bar 30.

[0063] In the exemplary embodiment, please combine with Figure 7 and Figure 8 There are multiple guide channels 300, which are spaced apart. This increases the contact area between the cleaning fluid and the cover plate 40, further improving the directional accuracy of the cover plate 40 in guiding the cleaning fluid, so that the cleaning fluid can be uniformly guided to the spray bar 30.

[0064] In this embodiment of the disclosure, such as Figure 7 As shown, the width W of the guide channel 300 does not change along the extension direction of the guide channel 300. It can be understood that in other embodiments, the width W of the guide channel 300 may gradually increase or gradually decrease along the extension direction of the guide channel 300. Furthermore, in other embodiments, the width W of the multiple guide channels 300 may not be completely consistent.

[0065] In this embodiment of the disclosure, such as Figure 7 As shown, the depth of the guide channel 300 gradually decreases from the middle to both ends of the guide channel 300. It can be understood that in other embodiments, the depth of the guide channel 300 may not change.

[0066] In this embodiment of the disclosure, such as Figure 7 As shown, the bottom of the flow guide channel 300 is arc-shaped. It can be understood that in other embodiments, the bottom of the flow guide channel 300 may also be planar.

[0067] In this embodiment of the disclosure, such as Figure 7 As shown, multiple guide channels 300 are arranged at equal intervals. It can be understood that in other embodiments, the multiple guide channels 300 may also be arranged at non-equal intervals. For example, the spacing between adjacent guide channels 300 in the multiple guide channels 300 gradually increases or gradually decreases from the middle of the guide surface 41 to both sides.

[0068] In the exemplary embodiment, please combine with Figure 9 and Figure 10 The guide channel 300 has a first end 301 away from the spray bar 30 and a second end 302 close to the spray bar 30, and the width of the guide channel 300 gradually decreases from the first end 301 to the second end 302. This causes the cleaning fluid to gradually converge and guide the spray bar 30 under the action of the guide channel 300, increasing the flow rate of the cleaning fluid acting on the spray bar 30 and the impact force of the cleaning fluid on the spray bar 30.

[0069] In this embodiment of the disclosure, such as Figure 9 As shown, the number of guide channels 300 is one. It can be understood that in other embodiments, the number of guide channels 300 may be two or more. The width of the multiple guide channels 300 may decrease at the same or different rates along the extension direction of the guide channels 300.

[0070] In this embodiment of the disclosure, such as Figure 9 As shown, the bottom of the flow guide channel 300 is arc-shaped. It can be understood that in other embodiments, the bottom of the flow guide channel 300 may also be planar.

[0071] In this embodiment of the disclosure, such as Figure 9 As shown, the depth of the guide channel 300 gradually decreases from the middle to both ends of the guide channel 300. It can be understood that in other embodiments, the depth of the guide channel 300 may not change.

[0072] In the exemplary embodiment, please combine with Figure 4a , Figure 4b and Figures 6 to 10The lid 40 also has a first stop 43 on the side facing the recycling position, which protrudes from the guide surface 41 on the side away from the spray bar 30. This first stop 43 stops the cleaning fluid flowing away from the spray bar 30, allowing at least a portion of the blocked cleaning fluid to flow back towards the spray bar 30. Furthermore, the first stop 43 prevents the cleaning fluid acting on the lid 40 from being directed to other areas that need to be kept dry, such as the outside of the basin 100, the connection between the lid 40 and the toilet seat 60, and other parts of the toilet seat 60, allowing the cleaning fluid to fall into the basin 100.

[0073] Please refer to the embodiments disclosed herein. Figure 4a , Figure 4b and Figures 6 to 10 The first stop portion 43 is fitted and matched with the outer edge of the guide surface 41 on the side away from the spray bar 30. It can be understood that in other embodiments, the first stop portion 43 and the outer edge of the guide surface 41 on the side away from the spray bar 30 may also be spaced apart, and the extension dimension of the first stop portion 43 is larger than the extension dimension of the outer edge of the guide surface 41 on the side away from the spray bar 30, to further increase the stopping area for the cleaning fluid. By increasing the size of the first stop portion 43 protruding from the guide surface 41, the stopping area for the cleaning fluid can be further increased. In this embodiment, the size of the first stop portion 43 protruding from the guide surface 41 does not change along the extension direction of the first stop portion 43 and remains consistent. It can be understood that in other embodiments, the size of the first stop portion 43 protruding from the guide surface 41 may also be inconsistent, and the size can be increased for locations with a larger cleaning fluid flow rate.

[0074] In the exemplary embodiments, please continue to refer to Figure 4a , Figure 4b and Figures 6 to 10 A second stop portion 44 is provided on each of the two opposite sides of the first stop portion 43, and the second stop portion 44 extends from the first stop portion 43 along the circumferential outer edge of the guide surface 41. This allows the first stop portion 43 and the second stop portion 44 to cover the side of the guide surface 41 away from the spray bar 30, thereby improving the stopping effect on the cleaning fluid flowing away from the spray bar 30 and preventing the cleaning fluid from being directed to other positions.

[0075] In this embodiment, the size of the second stop portion 44 protruding from the flow guide surface 41 is the same as the size of the first stop portion 43 protruding from the flow guide surface 41. It can be understood that in other embodiments, the size of the second stop portion 44 protruding from the flow guide surface 41 may not be the same as the size of the first stop portion 43 protruding from the flow guide surface 41.

[0076] In this embodiment, the wrapping size of the first stop 43 and the second stop 44 around the outer edge of the guide surface 41 is less than half the circumference of the outer edge of the guide surface 41. This avoids blocking the cleaning fluid of the guide spray rod 30 by the second stop 44, ensuring that the cleaning fluid directly guided to the spray rod 30 through the cover plate 40 can separate more smoothly from the cover plate 40.

[0077] In an exemplary embodiment, such as Figure 4a , Figure 4b As shown, the rotating shaft 42 of the toilet seat 40, which rotates relative to the toilet seat 60, and the moving path of the spray bar 30 are arranged vertically along the direction of gravity. The cleaning fluid generated by the cleaning assembly 50 can drive the toilet seat 40 to rotate around the rotating shaft 42 away from the spray bar 30. This ensures that the direction of the cleaning fluid flowing towards the spray bar 30 under the stopping action of the toilet seat 40 is in the same vertical plane as the direction of gravity, which is beneficial for guiding the cleaning fluid to the spray bar 30 and landing on the upper side of the spray bar 30. Under the action of gravity, the cleaning fluid can flow from the upper side of the spray bar 30 to the lower side of the spray bar 30, ensuring the cleaning effect on the spray bar 30. In this embodiment, the rotating shaft 42 is located on the side of the toilet seat 40 away from the spray bar 30. It can be understood that in other embodiments, the rotating shaft 42 can also be located between the side of the toilet seat 40 away from the spray bar 30 and the side of the toilet seat 40 away from the spray bar 30.

[0078] Since the rotating shaft 42 of the toilet seat 40 relative to the toilet seat 60 and the moving path of the spray bar 30 are set up and down along the direction of gravity, after the first stop part 43 and the second stop part 44 stop the cleaning liquid flowing away from the spray bar 30, the cleaning liquid can fall onto the spray bar 30 by gravity, avoiding waste of cleaning liquid and ensuring the cleaning effect on the spray bar 30.

[0079] In this embodiment, the cover plate 40 is provided with two opposing ear plates 45, which are rotatably connected to the toilet seat plate 60 via a pivot 42. To improve the strength of the ear plates 45, the ear plates 45 are thickened along the axial direction of the pivot 42. In addition, ribs 46 can also be connected between the ear plates 45 and the cover plate 40. Each ear plate 45 is provided with two ribs 46, which are respectively located on both sides of the pivot 42.

[0080] In the exemplary embodiment, please combine with Figure 4a , Figures 4b to 10The cover plate 40 includes a cover body 47 and a flow guide platform 48 disposed on the side of the cover body 47 facing the recycling position. The flow guide platform 48 protrudes outward from the cover body 47, and a flow guide surface 41 is disposed on the side of the flow guide platform 48 facing the recycling position. The flow guide platform 48 increases the strength of the cover plate 40, preventing deformation and vibration noise under the impact of the cleaning fluid. Furthermore, the flow guide platform 48 ensures the structural stability of the flow guide surface 41, reducing the impact of the flow guide groove 300 on the structural strength of the cover plate 40. The cover body 47 and the flow guide platform 48 can be detachably connected or integrally formed, or they can be joined together by a tight fit or ultrasonic welding. The first stop part 43 and the second stop part 44 can be detachably connected to the cover body 47 or integrally formed, or they can be joined together by a tight fit or ultrasonic welding.

[0081] It can be understood that in other embodiments, the flow guiding surface 41 can also be directly disposed on the cover 47.

[0082] In an exemplary embodiment, such as Figure 4a , Figure 7 , Figure 8 and Figure 10 As shown, the flow guide platform 48 includes a connecting portion 481 and a raised portion 482. The connecting portion 481 is disposed on the cover 47, and the raised portion 482 is disposed on the side of the connecting portion 481 facing the spray bar 30 and is inclined away from the cover 47. A notch 400 facing the spray bar 30 is formed between the raised portion 482 and the cover 47. In this way, the setting of the raised portion 482 can ensure the stability of the bending degree of the flow guide surface 41. The notch 400 formed between the raised portion 482 and the cover 47 makes the strength increase of the flow guide platform 48 on the side of the cover 47 near the spray bar 30 relatively small. In the process of relative sliding between the cover 47 and the spray bar 30 (for example, when the hydraulic pressure of the cleaning fluid is low), the cover 47 can use its own elastic deformation ability to prevent the cover 47 and the spray bar 30 from getting stuck due to relative sliding.

[0083] In an exemplary embodiment, such as Figure 4a , Figure 4b As shown, the thickness of the connecting portion 481 gradually increases from the side away from the spray bar 30 to the side closer to the spray bar 30, where the thickness is the dimension of the connecting portion 481 perpendicular to the cover body 47. This makes the center of gravity of the cover plate 40 closer to the spray bar 30, resulting in a larger torque of gravity on the cover plate 40 relative to the rotating shaft 42. During the impact of the cleaning fluid, the cover plate 40 has a stronger ability to resist the impact of the cleaning fluid, and its stopping effect on the cleaning fluid is more stable. In this embodiment of the present disclosure, the rotating shaft 42 is located on the side of the cover plate 40 away from the spray bar 30, making the torque of gravity on the cover plate 40 relative to the rotating shaft 42 even greater.

[0084] In the exemplary embodiment, please combine with Figure 3 and Figures 6 to 10 The cover 47 includes a first connecting plate 471 and a second connecting plate 472. The first connecting plate 471 is rotatably connected to the toilet seat 60. The second connecting plate 472 is disposed on the side of the first connecting plate 471 near the spray bar 30 and is inclined from the first connecting plate 471 toward the retracted position, thus making the structure of the cover 47 more stable and stronger in resisting the impact of cleaning fluid. A connecting part 481 is disposed on the first connecting plate 471 and the second connecting plate 472, so that the first connecting plate 471 and the second connecting plate 472 are also connected by the connecting part 481, further improving the structural stability of the cover 47.

[0085] In the exemplary embodiment, please combine with Figure 4a , Figures 4b to 10 The toilet seat 60 is provided with a first limiting member 70, and the seat 40 is provided with a second limiting member 49. The second limiting member 49 can rotate with the seat 40 to abut against the first limiting member 70, thereby limiting the rotation angle of the seat 40 relative to the toilet seat 60. This ensures the stability of the guide direction of the cleaning fluid by the seat 40, guaranteeing that the cleaning fluid can be guided to the spray nozzle 30. The first limiting member 70 can be directly provided on the toilet seat 60, or it can be provided on the toilet seat 60 through a fixing plate 80. Under the impact of the cleaning fluid, the second limiting member 49 can rotate with the seat 40 to abut against the first limiting member 70, ensuring that the cleaning fluid can be guided to the spray nozzle 30 by the stopping effect of the seat 40, preventing the seat 40 from failing to restrict the guidance of the cleaning fluid to the spray nozzle 30 under its own weight. Both the first limiting member 70 and the second limiting member 49 can be protruding structures, with the first limiting member 70 positioned on the rotation path of the second limiting member 49. The rotation angle of the toilet seat 40 relative to the toilet seat 60 is limited by the first limiting member 70 and the second limiting member 49, allowing the cleaning fluid to act on the position of the toilet seat 40 located in the middle of the guide surface 41, such as... Figure 6 , Figure 8 and Figure 10 As shown.

[0086] In this embodiment of the disclosure, such as Figure 4a , Figure 4b As shown, the fixing plate 80 is located above the cover plate 40 and is inclined into the basin cavity 100 to ensure that the splashed cleaning fluid can be deflected back into the basin cavity 100 by the fixing plate 80.

[0087] In the exemplary embodiment, please combine with Figure 4a , Figure 4b , Figures 6 to 10At least one of the first limiting member 70 and the second limiting member 49 has an elastic portion, which allows it to elastically abut against the other, improving the limiting fit between the first limiting member 70 and the second limiting member 49. This elastic portion provides a buffering effect when the first limiting member 70 and the second limiting member 49 abut, extending their lifespan and preventing excessive impact force during contact, which could lead to limiting failure. The elastic portion can be an elastic block made of an elastic material. It can also be an elastic arm. In this embodiment, the second limiting member 49 includes a connecting arm 491 and an elastic arm 492. The connecting arm 491 is disposed on the cover 47 and can be detachably connected to or integrally formed with the cover 47, or it can be connected by a tight fit or ultrasonic welding. One end of the elastic arm 492 is disposed on the connecting arm 491, and the other end is suspended, so as to provide a buffering effect when it abuts against the first limiting member 70. The connection between the connecting arm 491 and the elastic arm 492, on the side facing away from the first limiting member 70, is thickened with a rounded transition to improve the structural strength of the elastic arm 492. It can be understood that in other embodiments, the first limiting member 70 may also have the same structure as the second limiting member 49.
