[0002] As people's living standards improve, more and more people are paying attention to personal hygiene. Therefore, smart bathroom products are entering more and more homes, with smart toilets being a typical example. Existing smart toilet cleaning devices can clean specific parts of the body, using water washing instead of toilet paper. Technology, convenience, and hygiene are the future trends in bathroom development. Current cleaning devices are generally spray nozzles. When working, the nozzle moves back and forth along a track, spraying liquid from the outlet to clean specific parts of the body. After the liquid is sprayed out, some of the cleaned liquid drips onto the surface of the spray gun, easily contaminating it and affecting the cleaning effect. Some spray guns have only one function and cannot meet people's requirements for comprehensive cleaning. Currently, some self-cleaning spray guns have emerged, but their complex structure means that the cleaning effect on the spray gun itself is not yet optimal. Utility Model Content

With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0039] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0040] like Figures 1-15 As shown, this embodiment provides a flushing toilet seat assembly 1, which is pivotally mounted on the toilet body. The toilet seat assembly 1 includes a seat ring 10, a seat cover 20, a water inlet assembly 40, a valve core assembly 30, and a spray nozzle assembly 70. The seat cover 20 is pivotally mounted on the seat ring 10.

[0041] The seat ring 10 includes a housing 11, which includes a first housing 111 and a second housing 112 that can be assembled into one piece. A housing cavity is formed inside the housing 11, and the water inlet assembly 40, the valve core assembly 30, and the nozzle assembly 70 are installed in the housing cavity inside the housing 11. A baffle 113 is pivotally connected to the housing 11.

[0042] The water inlet assembly 40 includes a bend 41 and a threaded connector 42, which may be, for example, a double-coated copper nut. One end of the bend 41 is connected to the threaded connector 42, which is used to connect to a water source. The other end of the bend 41 is connected to the valve core assembly 30.

[0043] The valve core assembly 30 includes a valve core body 31, a knob 32, a first hose 33, and a second hose 34. The valve core body 31 is provided with a first pipe interface 311 and a second pipe interface 312. The knob 32 is connected to and can actuate the valve core body 31, thereby switching the bend 41 to connect with the first pipe interface 311, or switching the bend 41 to connect with the second pipe interface 312, or switching the bend 41 to the closed state.

[0044] Reference Figures 3-5 The nozzle assembly 70 has a first inlet 771 and a second inlet 772. A first pipe interface 311 is connected to the first inlet 771 via a first hose 33, and a second pipe interface 312 is connected to the second inlet 772 via a second hose 34.

[0045] Reference Figures 6-15The nozzle assembly 70 includes a seat 71, a spring 74, a self-cleaning sliding member 72, a seal 75, and a water inlet cap 77. The seat 71 has a cavity 711 with a first opening 713 and a second opening 712. The self-cleaning sliding member 72 is slidably disposed within the cavity 711. The two ends of the spring 74 abut against the seat 71 and the self-cleaning sliding member 72, respectively, providing a restoring force for the self-cleaning sliding member 72 to retract into the seat 71. The seat 71 has two parallel cavities 711. The two self-cleaning sliding members 72 are respectively installed in the two cavities 711. A sealing boss 714 is provided inside each cavity 711.

[0046] A water inlet cap 77 is installed on a base 71 and is sealed to one end of the base 71 by a sealing element 75, sealingly connecting the two first openings 713 of the two cavities 711. The water inlet cap 77 is provided with a first water inlet 771 and a second water inlet 772. The first water inlet 771 and the second water inlet 772 are respectively connected to the two cavities 711.

[0047] The self-cleaning sliding component 72 includes an end cap 721, a first sealing ring 722, a spray bar 723, a second sealing ring 724, and a nozzle 725. The nozzle 725 has a single-hole opening structure, thus providing a posterior wash function. Of course, the nozzle 725 can be replaced with a nozzle 725a, which has a three-hole structure, thus providing a feminine wash function. The nozzle 725a is installed on the self-cleaning sliding component 72a, and the replacement of the nozzle 725 with the nozzle 725a is simple and quick.

[0048] Reference Figures 6-15 The spray bar 723 has a hollow structure with an internal spray bar channel 7239. An end cap 721 is installed at the first end of the spray bar 723. The end cap 721 includes an end face 7211 and a side wall 7212 that are interconnected. The end face 7211 has multiple water inlet holes 7213, allowing the first water inlet 771 and the second water inlet 772 to respectively connect to the spray bar channels 7239 of the two spray bars 723.

[0049] The side wall 7212 is provided with a snap-fit ​​interface 7214, and the outer wall of the spray bar 723 is provided with a snap-fit ​​protrusion 7231. The snap-fit ​​protrusion 7231 is movably snapped into the snap-fit ​​interface 7214, so that the end cap 721 is movably installed on the first end of the spray bar 723, and the maximum stroke of the end cap 721 relative to the spray bar 723 is limited, thereby increasing the gap between the end face 7211 of the end cap 721 and the spray bar 723, and making the water intake smoother.

[0050] The first sealing ring 722 is installed on the spray bar 723. Specifically, the spray bar 723 is provided with a first sealing mounting groove 7232, the first sealing ring 722 is installed in the first sealing mounting groove 7232, and the end cap 721 is sleeved on the outer peripheral surface of the first sealing ring 722. The first sealing ring 722 has a sealing protrusion 7221 extending axially along its outer edge.

[0051] The nozzle 725 / 725a is snapped onto the second end of the spray bar 723, and a second sealing ring 724 is provided between the nozzle 725 / 725a and the second end of the spray bar 723 to form a seal between them. The second end of the spray bar 723 is provided with a second sealing mounting groove 7233 to install the second sealing ring 724.

[0052] Reference Figures 9-13 The self-cleaning sliding member 72 can overcome the elastic force of the spring 74 due to the action of water pressure and slide out through the second opening 712 of the seat body 71.

[0053] Reference Figure 10 , Figure 11 There is a gap S between the side wall 7212 of the end cap 721 and the inner wall of the cavity 711, which allows water to flow out. When the self-cleaning sliding member 72 is not slid out, water flows out through the gap S due to water pressure and contacts the outer wall of the spray bar 723.

[0054] The second opening 712 forms a water flow channel with the outer wall of the spray bar 723. Water flows out through the water flow channel, effectively cleaning the spray bar 723. Specifically, the spray bar 723 is cylindrical, and its outer wall has two arc-shaped grooves 7238. The two arc-shaped grooves 7238 are positioned opposite each other. The second opening 712 is formed by two opposing arc-shaped surfaces 7121 and two opposing planes 7122. The two arc-shaped surfaces 7121 fit into the outer wall of the spray bar 723, and the two planes 7122 correspond to the two arc-shaped grooves 7238, thus forming a water outlet 7124 between the planes 7122 and the arc-shaped grooves 7238 as a water flow channel. The two water outlets 7124 are located on opposite sides of the spray bar 723. Under water pressure, water flows out through the water outlets 7124, which serve as the water flow channel, effectively cleaning the opposite sides of the spray bar 723, resulting in more thorough cleaning and a better cleaning effect.

[0055] Reference Figure 10 , Figure 11 One of the upper planes 7122 of the second opening 712 is also recessed with a positioning opening 7123. The positioning opening 7123 can increase the water flow of the cleaning spray bar 723, thereby further improving the cleaning effect. In addition, the positioning opening 7123 can also cooperate with the positioning boss 7235 at the second end of the spray bar 723, thereby playing a positioning role for the self-cleaning sliding component 72.

[0056] Reference Figure 12 , Figure 13 When the self-cleaning sliding member 72 slides out to its position, it pushes open the baffle 113. Since the cavity 711 has a sealing boss 714, the first sealing ring 722 can abut against the sealing boss 714. The first sealing ring 722 abuts against the sealing boss 714 through the sealing protrusion 7221, preventing water from flowing out through the gap S. At this time, water is sprayed out from the opening of the nozzle 725 / nozzle 725a, thus providing a rinsing function. The nozzles 725 / nozzle 725a can each provide different rinsing functions, making them applicable to a wider range of situations.

[0057] A baffle 113 is pivotally connected to the housing 11. When the self-cleaning sliding member 72 is not slid out, the baffle 113 covers the nozzle assembly 70, and the nozzle assembly 70 is completely hidden in the housing cavity of the housing 11, making the appearance more aesthetically pleasing. When the self-cleaning sliding member 72 slides out into position, the self-cleaning sliding member 72 pushes open the baffle 113 to provide a rinsing function through the nozzle 725 / nozzle 725a.

[0058] This embodiment also provides a toilet, including a toilet body and a cover assembly 1 as described above, the cover assembly 1 being pivotally mounted on the toilet body.

[0059] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
