[0067] like Figures 1 to 4 As shown, Figures 1 to 4The structure of a toilet 100 in an embodiment of the present application is shown. The toilet 100 includes a toilet body 1 and a toilet cover device 2. The toilet cover device 2 is arranged at the upper end of the toilet body 1. The toilet cover device 2 includes an electronic accommodating unit. The toilet body 1 includes a waste receiving cavity 11, and a waste receiving space 111 is provided in the waste receiving cavity 11. The waste receiving space 111 is used to accommodate human excrement. A sewage outlet 113 is provided at the bottom of the sewage receiving cavity 11, and an excrement inlet 112 is provided at the top of the sewage receiving cavity 11. The sewage outlet 113 and the excrement inlet 112 are both connected to the sewage receiving space 111. Human excrement enters the sewage receiving space 111 from the excrement inlet 112 and can be discharged from the sewage receiving space 111 through the sewage outlet 113. The inner wall of the sewage receiving cavity 11 has a concave arc-shaped structure.

[0068] In some embodiments, the electronic housing unit is a housing 21. The housing includes a cover and a base, which together form a mounting cavity. The cover and base are detachably connected and can be detachably mounted on the toilet body 1.

[0069] like Figure 1 、 2 As shown, the toilet cover device 2 includes an electronic accommodating unit 21, a seat ring 22, a toilet cover 23 and a functional module 24. The electronic accommodating unit 21 is arranged on the top of the toilet cover 23 and is located at the rear side of the waste receiving cavity 11. The electronic accommodating unit 21 is connected to the toilet body 1. The electronic accommodating unit 21 can be a thin shell structure. Figure 3 、 6 As shown in Figures 7 and 8, the electronic housing unit 21 is provided with a mounting cavity 210. The electronic housing unit 21 is also provided with an extension opening 21231. Extension opening 21231 is located on a side of the electronic housing unit 21 adjacent to the waste receiving space 111. Extension opening 21231 communicates with the mounting cavity 210. Extension opening 21231 also communicates with the waste receiving cavity 11. The seat 22 and toilet lid 23 are both rotatably connected to the electronic housing unit 21.

[0070] The functional module 24 is at least partially housed within the mounting cavity 210. The functional module 24 is configured to extend from the extension opening 21231 of the electronics housing unit 21 into the waste receiving cavity 11 to perform its corresponding function and then retract from the waste receiving cavity 11 through the extension opening 21231. The portion of the functional module 24 extending into the waste receiving cavity 11 is provided with a first sealing portion 24a. The extension opening 21231 of the electronics housing unit 21 is provided with a second sealing portion 21a. When the functional module 24 is retracted from the waste receiving cavity 11, the first sealing portion 24a abuts against the second sealing portion 21a at the extension opening 21231, thereby sealing the extension opening 21231 of the electronics housing unit 21.

[0071] In some embodiments, the toilet lid assembly 2 includes a housing, and the electronics housing unit is used to accommodate the functional module 24. The electronics housing unit includes a base, which is removably mounted within the housing 21 or removably mounted on the toilet body 1. In other words, the electronics housing unit can be a separate storage structure from the toilet lid assembly 2. In other embodiments, the base can be a part of the toilet body 1.

[0072] Therefore, when the functional module 24 is retracted from the dirt receiving cavity 11 to the storage position, the first sealing portion 24a on the functional module 24 abuts against the second sealing portion 21a on the protruding port 21231, thereby sealing the protruding port 21231, which can completely prevent stains such as urine from entering the electronic containing unit 21 through the protruding port 21231.

[0073] In an illustrative embodiment, Figure 9 、 10 As shown, the functional module 24 can be a drying module 242 or a rinsing module 241. The rinsing module 241 is used to rinse the human body. The drying module 242 is used to dry moisture off the surface of the human body. The functional module 24 is disposed at one end of the mounting cavity 210 near the extension opening 21231. The functional module 24 includes a main body 2401 and a movable portion 2402. The main body 2401 is disposed within the mounting cavity 210 of the electronic accommodating unit 21. The main body 2401 is connected to the electronic accommodating unit 21. The movable portion 2402 can be constructed as a strip-shaped structure. The movable portion 2402 and the main body 2401 can be connected by a sliding connection. For example, the main body 2401 may be provided with a slideway, and one end of the movable portion 2402 is disposed within the slideway and can slide along the slideway. The sliding direction of the movable portion 2402 is the same as the extension direction of the movable portion 2402. The movable portion 2402 is located on the side of the main body 2401 near the extension opening 21231. The movable portion 2402 is provided through the extension opening 21231. The movable portion 2402 of the functional module 24 is configured to be able to extend out of the installation cavity 210 through the extension opening 21231, and also to be able to retract into the installation cavity 210 through the extension opening 21231. The movable portion 2402 of the functional module 24 can extend out of the installation cavity 210 to reach the working position, and the movable portion 2402 can also be retracted into the installation cavity 210 to reach the storage position. When the movable portion 2402 is in the storage position, the end surface of the movable portion 2402 facing the outside of the installation cavity 210 is flush with the outer surface of the electronic accommodating unit 21. The end surface of the movable portion 2402 facing the outside of the installation cavity 210 is not provided with an opening, and the end surface of the movable portion 2402 facing the outside of the installation cavity 210 can be a plane. When observed from the moving direction of the movable portion 2402 of the functional module 24, the movable portion 2402 blocks the main body 2401.

[0074] The movable portion 2402 can completely cover the main body 2401 to prevent dirt from entering the electronic containing unit 21 through the extension opening 21231.

[0075] In an illustrative embodiment, Figure 10 、 12 As shown, the first sealing portion 24 a includes a first protruding ring 241 a protruding radially outward on the functional module 24 . The first protruding ring 241 a may be provided at an end of the movable portion facing away from the installation cavity 210 .

[0076] The second sealing portion 21a includes a second protruding ring 211a protruding radially inward from the protruding opening 21231. The second protruding ring 211a is an annular structure. The outer circumference of the second protruding ring 211a is connected to the inner wall of the protruding opening 21231.

[0077] The first protruding ring 241a and / or the second protruding ring 211a can be a rigid structure, for example, both made of plastic, ceramic, metal, etc. The first protruding ring 241a and / or the second protruding ring 211a can be an elastic structure, for example, made of rubber or silicone. For example, the first protruding ring 241a is a protrusion extending radially outward from the outer wall of the functional module 24, and the second protruding ring 211a is formed at the end of a slideway of the main body 2401. The second protruding ring 211a is located in the movable path of the first protruding ring 241a during the retraction of the functional module 24.

[0078] In an exemplary embodiment, the first protruding ring 241 a of the first sealing portion 24 a abuts against the second sealing portion 21 a along the moving direction of the functional module 24 .

[0079] like Figure 11 、 12 As shown, the second protrusion of the second sealing portion 21a includes a first sealing protrusion 24011. The first sealing protrusion 24011 is arranged on the inner wall of the extension opening 21231 of the electronic accommodating unit 21. The first sealing protrusion 24011 protrudes radially inward on the inner wall of the extension opening 21231. The first sealing protrusion 24011 can be constructed as an annular protrusion. The first sealing protrusion 24011 is located at one end of the extension opening 21231 of the electronic accommodating unit 21 close to the mounting cavity 210. The movable portion 2402 is penetrated by the first sealing protrusion 24011, and the movable portion 2402 and the first sealing protrusion 24011 are clearance-fitted.

[0080] The first protruding ring 241a of the first sealing portion 24a includes a first sealing member 28. The first sealing member 28 is constructed as an annular structure that is sleeved on the movable portion 2402. The first sealing member 28 is fixedly connected to the movable portion 2402. The first sealing member 28 can enter and exit the extension opening 21231 as the movable portion 2402 slides. When the movable portion 2402 is in the storage position, the first sealing member 28 is located on the side of the first sealing protrusion 24011 away from the installation cavity 210, and the first sealing member 28 abuts against the side of the first sealing protrusion 24011 away from the installation cavity 210. The distance from the outer edge of the first sealing member 28 to the axis of the first sealing member 28 is greater than the distance from the inner edge of the first sealing protrusion 24011 to the axis of the first sealing protrusion 24011.

[0081] In this way, when the movable portion 2402 moves to the operating position, the first seal 28 moves with the movable portion 2402 to the outside of the extension opening 21231, and the first seal 28 is not subjected to pressure from the electronic housing unit 21. When the movable portion 2402 moves to the storage position, the first seal 28 abuts against the side of the first sealing protrusion 24011 facing away from the installation cavity 210. The first seal 28 presses against the side of the first sealing protrusion 24011 from the outward side of the first sealing protrusion 24011, thereby achieving a sealing effect. Because the first seal 28 only produces a tight seal when the movable portion 2402 returns to the storage position, wear on the first seal 28 is minimized during long-term use, and the torque requirement for the power source driving the movable portion 2402 is reduced. Furthermore, the first seal 28 contacts and seals the side of the first sealing protrusion 24011 axially in the extension opening 21231. The sealing surface between the first seal 28 and the first sealing protrusion 24011 is smooth and tightly contacted, resulting in a very low leakage rate.

[0082] In an illustrative embodiment, the movable portion 2402 is provided with a first mounting groove 24022. The first mounting groove 24022 is formed by an inward depression on the outer circumference of the movable portion 2402. The first mounting groove 24022 can be configured as an annular groove extending along the circumference of the movable portion 2402. The first mounting groove 24022 can be provided at an end of the movable portion 2402 away from the mounting cavity 210. The inner edge of the first seal 28 is embedded in the first mounting groove 24022 of the movable portion 2402. The thickness of the inner edge of the first seal 28 is greater than the width of the first mounting groove 24022. The first seal 28 and the first mounting groove 24022 can be an interference fit.

[0083] Since the inner edge of the first sealing member 28 is embedded in the first mounting groove 24022 of the movable portion 2402 , the first sealing member 28 can be firmly fixed on the movable portion 2402 , and no gap exists between the first sealing member 28 and the movable portion 2402 .

[0084] In an exemplary embodiment, the first sealing member 28 is bonded to the movable portion 2402. The first sealing member 28 may be bonded to the outer peripheral surface of the movable portion 2402 by adhesive.

[0085] The first sealing member 28 is connected to the movable portion 2402 by bonding, which can firmly fix the first sealing member 28 on the movable portion 2402 and ensure the sealing performance between the first sealing member 28 and the movable portion 2402.

[0086] In one exemplary embodiment, the first raised ring 241a of the first sealing portion 24a further includes a second sealing protrusion 24021, which is disposed on the movable portion 2402. The second sealing protrusion 24021 is disposed at the end of the movable portion 2402 remote from the mounting cavity 210. The second sealing protrusion 24021 extends radially outward from the outer circumference of the movable portion 2402. The second sealing protrusion 24021 may be configured as an annular protrusion. The first sealing member 28 is disposed on the side of the second sealing protrusion 24021 that is adjacent to the mounting cavity 210, and the first sealing member 28 abuts the side of the second sealing protrusion 24021 that is adjacent to the mounting cavity 210. The end surface of the first sealing member 28 that is remote from the mounting cavity 210 and the side surface of the second sealing protrusion 24021 that is adjacent to the mounting cavity 210 may be adhesively bonded. The side surface of the second sealing protrusion 24021 that is remote from the mounting cavity 210 is flush with the end surface of the movable portion 2402 that is remote from the mounting cavity 210.

[0087] In this way, when the movable part 2402 is in the storage position, the second sealing protrusion 24021 of the movable part 2402 can apply pressure to the first sealing member 28 from the side of the first sealing member 28 facing away from the first sealing protrusion 24011, and the pressure is directed toward the first sealing protrusion 24011, thereby improving the sealing performance between the first sealing protrusion 24011 and the first sealing member 28.

[0088] In an exemplary embodiment, both end surfaces of the first sealing member 28 are planar. The first sealing member 28 is a flat gasket. The first sealing member 28 can form a seal by abutting the side surfaces of the first sealing protrusion 24011 with the planar end surfaces. This first sealing member 28 has a simple structure and is easy to manufacture.

[0089] In another exemplary embodiment, the second protruding ring 211 a of the second sealing portion 21 a abuts against the first sealing portion 24 a along the moving direction of the functional module 24 .

[0090] like Figure 14As shown, the first raised ring 241a of the first sealing portion 24a includes a second sealing protrusion 24021, which can be configured as an annular protrusion. The second sealing protrusion 24021 extends radially outward from the outer circumference of the movable portion 2402. The second sealing protrusion 24021 is disposed at the end of the movable portion 2402 that is distal to the mounting cavity 210. The side of the second sealing protrusion 24021 that is distal to the mounting cavity 210 is flush with the end surface of the movable portion 2402 that is distal to the mounting cavity 210.

[0091] The second protruding ring 211a of the second sealing portion 21a also includes a second sealing member 28a having an annular structure. The second sealing member 28a is disposed on the inner wall of the extension opening 21231. The outer edge of the sealing member 28a is connected to the inner wall of the extension opening 21231. The movable portion 2402 is disposed through the second sealing member 28a, and the movable portion 2402 and the second sealing member 28a may be loosely fitted. The second sealing member 28a is located on the side of the second sealing protrusion 24021 that is closer to the mounting cavity 210. The distance between the inner edge of the second sealing member 28a and the axis of the second sealing protrusion 24021 is less than the distance between the inner edge of the second sealing protrusion 24021 and the axis of the second sealing protrusion 24021. When the movable portion 2402 is in the stored position, the second sealing member 28a abuts against the side of the second sealing protrusion 24021 that is closer to the mounting cavity 210.

[0092] Thus, when the movable portion 2402 moves to the working position, the second sealing protrusion 24021 moves with the movable portion 2402 to the outside of the extension opening 21231, and the second sealing member 28a is fixed to the extension opening 21231. The second sealing member 28a is not squeezed by the second sealing protrusion 24021 of the movable portion 2402. When the movable portion 2402 moves to the storage position, the second sealing member 28a abuts against the side of the second sealing protrusion 24021 near the installation cavity 210. The second sealing protrusion 24021 presses against the side of the second sealing protrusion 24021 from the sealing member 28a toward the installation cavity 210, thereby achieving a sealing effect. Because the second sealing protrusion 24021 only presses against the second sealing protrusion 24021 when the movable portion 2402 returns to the storage position, the wear of the second sealing member 28a is minimized during long-term use, and the torque requirement of the power source driving the movable portion 2402 is reduced. At the same time, the second sealing member 28a contacts and seals the side surface of the second sealing protrusion 24021 in the axial direction of the extension port 21231. The sealing surface between the second sealing member 28a and the second sealing protrusion 24021 is flat and in close contact, and the leakage rate is very low. In an exemplary embodiment, as shown in FIG. Figure 16 As shown, the outer edge of the second sealing member 28b is bonded to the inner wall of the extension opening 21231 of the electron accommodating unit 21. The second sealing member 28b can be bonded to the inner wall of the extension opening 21231 of the electron accommodating unit 21 by adhesive.

[0093] The second sealing member 28b is connected to the electronic accommodating unit 21 by bonding, which can firmly fix the second sealing member 28b on the electronic accommodating unit 21 and ensure the sealing performance between the second sealing member 28b and the inner wall of the extension port 21231.

[0094] In another exemplary embodiment, Figure 18 As shown, a second mounting groove 24012 is provided on the inner wall of the extension opening 21231, and the outer edge of the second sealing member 28c is embedded in the second mounting groove 24012. The second mounting groove 24012 can be formed by a depression in the inner wall of the extension opening 21231. The second mounting groove 24012 can be configured as an annular groove extending along the circumference of the extension opening 21231. The second mounting groove 24012 can be provided at an end of the extension opening 21231 near the mounting cavity 210. The inner edge of the second sealing member 28c is embedded in the second mounting groove 24012. The second sealing member 28c and the second mounting groove 24012 can be an interference fit.

[0095] Since the inner edge of the second sealing member 28c is embedded in the second mounting groove 24012 of the inner wall of the extension opening 21231 , the second sealing member 28c can be firmly fixed on the electronic accommodating unit 21 , and no gap exists between the second sealing member 28c and the inner wall of the extension opening 21231 .

[0096] In an illustrative embodiment, Figure 18 As shown, the second protrusion of the second sealing portion 21a includes a first sealing protrusion 24011, which is disposed on the inner wall of the extension opening 21231 of the electronic accommodating unit 21 and protrudes radially inward. A second mounting groove 24012 is disposed on a side of the first sealing protrusion 24011 away from the mounting cavity 210. The opening of the second mounting groove 24012 faces the second sealing member 28c. The depth of the second mounting groove 24012 is parallel to the axial direction of the extension opening 21231.

[0097] The second sealing member 28c includes a ring body 281c and an annular protrusion 282c. The ring body 281c is disposed on the side of the first sealing protrusion 24011 away from the mounting cavity 210. The annular protrusion 282c is disposed on the side of the ring body 281c closer to the first sealing protrusion 24011. The annular protrusion 282c may be disposed on the outer edge of the ring body 281c. The annular protrusion 282c is embedded in the second mounting groove 24012 on the inner wall of the extension opening 21231. The radial thickness of the annular protrusion 282c is greater than or equal to the width of the second mounting groove 24012.

[0098] In this way, an interference fit is formed between the second sealing member 28c and the second mounting groove 24012 of the electronic accommodating unit 21, and the second sealing member 28c is fixed on the electronic accommodating unit 21. At the same time, since the second mounting groove 24012 is arranged on the side of the first sealing protrusion 24011 away from the mounting cavity 210, it is convenient to insert the annular protrusion 282c into the second mounting groove 24012.

[0099] In another exemplary embodiment, Figure 21 Functional module 24 includes a first sealing portion 24a, which includes a first raised ring 241a. This ring includes a first sealing element 28f. The electronics housing unit includes a second sealing portion 21a. This second sealing element includes a second raised ring 211a. This second raised ring 211a includes a second sealing element 28d. First sealing element 28f abuts against second sealing element 28d when functional module 24 is retracted from waste receiving cavity 11.

[0100] The first seal 28f is connected to the movable portion 2402. The first seal 28f is constructed as an annular structure that is sleeved on the movable portion 2402. There is a clearance fit between the first seal 28f and the inner wall of the extension opening 21231. The second seal 28d is connected to the inner wall of the extension opening 21231 of the electron accommodating unit 21. The second seal 28d is constructed as an annular structure that is arranged on the inner wall of the extension opening 21231. The movable portion 2402 is inserted through the second seal 28d. There is a clearance fit between the second seal 28d and the movable portion 2402. The outer diameter of the first seal 28f is larger than the inner diameter of the second seal 28d.

[0101] When the movable portion 2402 is located at the storage position, the first sealing member 28 f is located on a side of the second sealing member 28 d away from the installation cavity 210 , and the end surfaces of the first sealing member 28 f and the second sealing member 28 d that are close to each other abut against each other.

[0102] Thus, when the movable portion 2402 moves to the working position, the first seal 28f moves with the movable portion 2402 to the outside of the extension opening 21231, separating the first seal 28f from the second seal 28d, and no pressure is applied between the first seal 28f and the second seal 28d. When the movable portion 2402 moves to the storage position, the adjacent end surfaces of the first seal 28f and the second seal 28d abut against each other, partially overlapping and squeezing each other in the radial direction, thereby sealing the gap between the outer wall of the movable portion 2402 and the inner wall of the telescopic opening. Because the first seal 28f presses against the second seal 28d to achieve a seal only when the movable portion 2402 returns to the storage position, the wear of the first seal 28f and the second seal 28d is minimal during long-term use, and the torque requirement for the power source driving the movable portion 2402 is lower. At the same time, the end face of the first sealing member 28f contacts and seals with the end face of the second sealing member 28d. The sealing surface between the first sealing member 28f and the second sealing member 28d is flat and in close contact, and the leakage rate is very low.

[0103] In an exemplary embodiment, the first sealing member 28f is bonded to the movable portion 2402. The first sealing member 28f can be bonded to the movable portion 2402 using adhesive. Alternatively, the movable portion 2402 is provided with a first mounting groove 24022, and the inner edge of the first sealing member 28f is embedded in the first mounting groove 24022.

[0104] The first sealing member 28 f is adhered to the movable portion 2402 , or the inner edge of the first sealing member 28 f is embedded in the first mounting groove 24022 of the movable portion 2402 , so that the first sealing member 28 f can be firmly fixed on the movable portion 2402 .

[0105] In an illustrative embodiment, Figure 21 As shown, the second sealing member 28d is bonded to the inner wall of the extension opening 21231 of the electronic accommodating unit 21. Alternatively, a second mounting groove 24012 is provided on the inner wall of the extension opening 21231 of the electronic accommodating unit 21, and the outer edge of the second sealing member 28d is embedded in the second mounting groove 24012.

[0106] like Figure 21 As shown, the second sealing member 28d is bonded to the inner wall of the extension opening 21231 of the electronic accommodating unit 21, or as Figure 23 As shown, the outer edge of the second sealing member 28h is embedded in the second mounting groove 24012 of the inner wall of the extension opening 21231 , and the second sealing members 28d and 28h can be firmly fixed on the extension opening 21231 of the electronic accommodating unit 21 .

[0107] In another exemplary embodiment, the first protruding ring 241 a of the first sealing portion 24 a is in sealing contact with the second sealing portion 21 a via its outer circumferential surface.

[0108] like Figure 25 As shown, the first protruding ring 241a of the first sealing portion 24a includes a first sealing member 28I. The first sealing member 28I is annular in structure. The first sealing member 28I is encircled by the outer circumference of the movable portion 2402. The outer edge of the first sealing member 28I is connected to the outer circumference of the movable portion 2402. The radial thickness of the first sealing member 28I is greater than the gap width between the outer circumference of the movable portion 2402 and the inner wall of the extension port 21231.

[0109] The second sealing portion 21a is the inner wall of the extension opening 21231. When the movable portion 2402 is in the stored position, the first sealing member 28I is disposed in the gap between the inner wall of the extension opening 21231 and the outer wall of the movable portion 2402. The first sealing member 28I is compressed by the radially inward pressure exerted by the inner wall of the extension opening 21231 and the radially outward pressure exerted by the movable portion 2402.

[0110] In this way, since the first seal 28I is in a compressed state, when the movable part 2402 is in the storage position, the outer peripheral surface of the first seal 28I is tightly attached to the movable part 2402 and the first seal 28I is tightly attached to the inner wall of the extension port 21231. The first seal 28I blocks the gap between the outer peripheral surface of the movable part 2402 and the inner wall of the extension port 21231, thereby achieving sealing of the gap.

[0111] In another exemplary embodiment, the second protruding ring 211 a of the second sealing portion 21 a is in sealing contact with the first sealing portion 24 a via its inner circumferential surface.

[0112] like Figure 27 As shown, the second convex ring 211a of the second sealing portion 21a includes a second sealing member 28m. The second sealing member 28m is constructed as an annular structure. The outer edge of the second sealing member 28m is bonded to the inner wall of the extension port 21231 of the electronic accommodating unit 21. The second sealing member 28m can be bonded to the inner wall of the extension port 21231 of the electronic accommodating unit 21 by adhesive. The second sealing member 28m is connected to the electronic accommodating unit 21 by bonding, which can firmly fix the second sealing member 28m on the electronic accommodating unit 21, while also ensuring the sealing performance between the second sealing member 28m and the inner wall of the extension port 21231.

[0113] The thickness of the second sealing member 28 m in the radial direction is greater than the width of the gap between the outer peripheral surface of the movable portion 2402 and the inner wall of the extension port 21231 .

[0114] The first sealing portion 24a is the inner wall of the extension opening 21231. When the movable portion 2402 is in the stored position, the second sealing member 28m is disposed in the gap between the inner wall of the extension opening 21231 and the outer wall of the movable portion 2402. The second sealing member 28m is compressed by the radially inward pressure exerted by the inner wall of the extension opening 21231 and the radially outward pressure exerted by the movable portion 2402.

[0115] In this way, since the second sealing member 28m is in a compressed state, when the movable part 2402 is in the storage position, the outer peripheral surface of the second sealing member 28m is tightly attached to the movable part 2402 and the second sealing member 28m is tightly attached to the inner wall of the extension port 21231. The second sealing member 28m blocks the gap between the outer peripheral surface of the movable part 2402 and the inner wall of the extension port 21231, thereby achieving sealing of the gap.

[0116] In another exemplary embodiment, Figure 29 As shown, the second protruding ring 211a of the second sealing portion 21a includes a second sealing member 28n. A second mounting groove 24012 is provided on the inner wall of the extension opening 21231, and the outer edge of the second sealing member 28n is embedded in the second mounting groove 24012. The second mounting groove 24012 can be formed by a depression in the inner wall of the extension opening 21231. The second mounting groove 24012 can be configured as an annular groove extending along the circumference of the extension opening 21231. The second mounting groove 24012 can be provided at an end of the extension opening 21231 near the mounting cavity 210. The inner edge of the second sealing member 28n is embedded in the second mounting groove 24012. The second sealing member 28n and the second mounting groove 24012 can be an interference fit.

[0117] Since the inner edge of the second sealing member 28n is embedded in the second mounting groove 24012 of the inner wall of the extension opening 21231 , the second sealing member 28n can be firmly fixed on the electronic accommodating unit 21 , and no gap exists between the second sealing member 28n and the inner wall of the extension opening 21231 .

[0118] In an illustrative embodiment, Figure 30 As shown, the elastic compression amount A of the first sealing member 28 is equal to the difference between the radial thickness of the first sealing member 28 and the width of the gap between the outer circumference of the movable portion 2402 and the inner wall of the extension opening 21231. The elastic compression amount A of the first sealing member 28 has a value range of 0.15 mm ≤ A ≤ 1.3 mm.

[0119] When the elastic compression amount A of the first seal 28 is within the above range, it can not only prevent the first seal 28 from changing from an interference fit to a clearance fit after multiple frictions with the movable part, thereby reducing the sealing and dirt-blocking function of the first seal 28, but also avoid the movable part 2402 from sliding and getting stuck due to excessive friction between the first seal 28 and the movable part 2402.

[0120] In an illustrative embodiment, Figure 31 As shown, the first sealing member 28p is in surface contact with the inner wall of the extension port 21231.

[0121] In an illustrative embodiment, Figure 32 As shown, there is line contact between the first sealing member 28q and the inner wall of the extension port 21231.

[0122] In an exemplary embodiment, the first sealing member 28 has a friction surface that can slide and rub against the inner wall of the extension opening 21231. The first sealing member 28 is fixedly connected to the movable portion 2402, and the friction surface is the outer peripheral surface of the sealing ring. Figure 30 As shown, in the cross section through the axis of the first sealing member 281 , the shape of the friction surface is an isosceles trapezoid.

[0123] In some embodiments, in a cross section passing through the axis of the first seal 282 , the friction surface has a shape of a right-angled trapezoid.

[0124] In some embodiments, in a cross section passing through the axis of the first seal 283 , the friction surface has a semicircular arc shape.

[0125] In some embodiments, in a cross section through the axis of the first seal 284 , the friction surface has a shape of a quarter circle arc.

[0126] In some embodiments, in a cross section passing through the axis of the first seal 285 , 286 , the friction surface has a square wave shape, and the number of square waves may be, for example, two or four.

[0127] In some embodiments, in a cross section through the axis of the first seal 287 , the friction surface has a V-shape.

[0128] In some embodiments, in a cross section through the axis of the first seal 288 , the friction surface has a sawtooth waveform shape.

[0129] In some embodiments, in a cross section passing through the axis of the first seal 289 , 290 , the friction surface has a semicircular wave shape, and the number of semicircular waves may be three or two.

[0130] The friction surfaces of the above-mentioned various shapes can reduce the friction force on the friction surface, improve the sliding smoothness of the movable part 2402, and improve the sealing effect of the seal.

[0131] In an illustrative embodiment, the functional module 24 is a flushing module 241. The flushing module 241 is used to clean the user when extending into the waste receiving cavity 11. The flushing module 241 includes a movable part, and the movable part is a spray rod 2411. The spray rod 2411 is provided with a nozzle. The nozzle is arranged on the side wall of the spray rod 2411, and the nozzle can be upward. The nozzle can spray out cleaning water for cleaning the human body. The extension port 21231 includes a flushing extension port 21232, and the spray rod 2411 of the flushing module 241 can extend from the flushing extension port 21232 or retract into the installation cavity 210. The nozzle is located upstream of the first sealing portion 24a and / or the second sealing portion 21a in the direction of extending into the waste receiving cavity 11 along the movable part.

[0132] In this way, after the spray rod 2411 is inserted into the dirt receiving cavity 11, clean water can be sprayed out through the nozzle to clean the human body.

[0133] In an illustrative embodiment, the functional module 24 is a drying module 242. The drying module 242 is used to dry the user or the toilet when it extends into the waste receiving cavity 11. The drying module 242 includes a movable part, which is a drying channel 2421. The drying channel is provided with an air outlet for ejecting air flow, and the air outlet can be arranged upward. The air outlet is located upstream of the first sealing part 24a and / or the second sealing part 21a along the direction in which the drying channel extends into the waste receiving cavity 11. The drying channel 2421 can deliver hot air to dry the human body. The extension port 21231 on the end 2122 includes a drying extension port 21233. The drying channel 2421 of the drying module 242 can extend from the drying extension port 21233 or retract into the installation cavity 210.

[0134] In this way, after the drying tunnel 2421 extends into the waste receiving cavity 11, hot air can be ejected through the air outlet to dry the human body and / or the toilet.

[0135] In an illustrative embodiment, the seat ring 22 is an annular structure. The seat ring 22 may be in the shape of a roughly elliptical ring. The seat ring 22 and the toilet lid 23 are both rotatably connected to the electronic accommodating unit 21. The seat ring 22 may be hinged to the electronic accommodating unit 21. The seat ring 22 can rotate relative to the electronic accommodating unit 21 around a horizontal axis of rotation. The seat ring 22 can rotate to a closed state covering the top of the toilet body 1, and aligning the central through hole of the seat ring 22 with the excrement inlet 112 of the waste receiving cavity 11. In the closed state, a human body can sit on the seat ring 22, and the seat ring 22 can support the human body. The seat ring 22 can also rotate to an open state with one end facing upward. In the open state, a man can urinate while standing without contaminating the seat ring 22.

[0136] When the seat ring 22 is in the open position, the lower edge of the seat ring 22 projects vertically onto the upper surface of the electronics housing unit 21. This projection is a line extending laterally across the upper surface of the housing. The upper surface of the electronics housing unit 21 is free of any openings or gaps between this projection and the end of the electronics housing unit 21 proximal to the waste receiving space 111 of the toilet 100. The end surface of the electronics housing unit 21 proximal to the waste receiving space 111 is free of any openings or gaps. This opening can be a through hole or a blind hole.

[0137] When the seat ring 22 is in the open state, the upper surface of the electronic accommodating unit 21 is projected into the area between the lower edge of the seat ring 22 and the end of the electronic accommodating unit 21 close to the waste receiving space 111 of the toilet 100, and the end surface of the electronic accommodating unit 21 close to the waste receiving space 111 are both easily contaminated by urine when men urinate while standing. However, there are no openings in these two areas, and the dirt in these two areas can be flushed clean by flushing with water. There will be no accumulation of dirt in the opening, making it difficult to clean.

[0138] In an illustrative embodiment, Figure 6 、 7 As shown, the electronic accommodating unit 21 is provided with an end portion 2122 that extends into the waste receiving space 111 of the toilet body 1. The end portion 2122 is located at the bottom of one end of the electronic accommodating unit 21 close to the waste receiving space 111 and protrudes into the waste receiving space 111. The end portion 2122 includes a lower surface 21220 exposed in the waste receiving space 111, and the lower surface 21220 of the end portion 2122 is flat. The lower surface 21220 of the end portion 2122 is provided with a protrusion 21231. The shape of the protrusion 21231 is not limited, and the protrusion 21231 can be a rectangular opening or a circular opening.

[0139] In related art, the lower surface 21220 of the toilet lid device 2 exposed in the waste receiving space 111 is typically uneven. When excrement falls into the water in the waste receiving space 111, some of it may splash onto the lower surface 21220. Due to the unevenness of the lower surface 21220, some corners are difficult to clean with a brush. In contrast, the lower surface 21220 of the end portion 2122 of the toilet lid device 2 exposed in the waste receiving space 111 in the embodiment of the present application is flat, eliminating any blind spots and making it easier to clean, thus improving the user experience. Furthermore, the extension opening 21231 is located on the lower surface 21220 of the end portion 2122, preventing it from being directly splashed by urine from men urinating while standing.

[0140] In an illustrative embodiment, multiple functional modules 24 and extension ports 21231 are provided. Multiple functional modules 24 can extend from and retract into the installation cavity 210 from the multiple extension ports 21231, respectively. The lower surface 21220 includes an opening surface 2123. The opening surface 2123 is a plane facing the front and lower part of the electronic accommodating unit 21. All extension ports 21231 are provided on the opening surface 2123. The opening surface 2123 is an inclined surface and faces the front and lower part of the electronic accommodating unit 21. The functional module 24 can extend from the extension port 21231 on the opening surface 2123 to the bottom of the excrement inlet 112 of the waste receiving cavity 11 to clean or dry the human body.

[0141] The opening surface 2123 is constructed as a downwardly inclined plane, which has no blind spots for cleaning and is easy to clean. At the same time, it is also beneficial for the droplets splashed onto the opening surface 2123 to slide down.

[0142] In an illustrative embodiment, Figure 6 、 7 As shown, the lower surface 21220 of the end portion 2122 further includes a lower end surface 2124 and two side surfaces 2125. The lower end surface 2124 of the end portion 2122 faces downward from the end portion 2122 and is connected to the bottom edge of the opening inclined surface. The two side surfaces 2125 of the end portion 2122 are respectively connected to opposite sides of the lower end surface 2124, and the two side surfaces 2125 of the end portion 2122 are also respectively connected to opposite sides of the opening surface 2123. The lower end surface 2124 can be a plane. The side surfaces 2125 can be plane or curved. The transition between the lower end surface 2124 and the two side surfaces 2125 is smooth. The lower end surface 2124 and the opening surface 2123 can form an obtuse angle. The opening surface 2123 and the side surfaces 2125 can form an obtuse angle.

[0143] In this way, the lower end surface 2124 and the two side surfaces 2125 are flat, and there is a smooth transition between the lower end surface 2124 and the two side surfaces 2125, without any blind spots for cleaning, making cleaning easier.

[0144] In an illustrative embodiment, Figure 6 、 7 As shown, the toilet lid assembly 2 further includes a brush ring nozzle module 25. The brush ring nozzle module 25 is disposed within the mounting cavity 210 of the electronics housing unit 21 and includes a brush ring nozzle 251 and a drive mechanism. The drive mechanism may be a motor. The brush ring nozzle 251 is configured to rotate relative to the electronics housing unit 21. The brush ring nozzle 251 may be configured in an L-shape. The drive mechanism is connected to the brush ring nozzle 251 and is configured to drive the brush ring nozzle 251 to rotate.

[0145] An inlet and outlet 21241 is also provided on the lower end surface 2124 of the end portion 2122. The inlet and outlet 21241 is connected to the mounting cavity 210. The drive mechanism is configured to both drive the brush ring nozzle 251 to rotate until it extends out of the electronic accommodating unit 21 through the inlet and outlet 21241 of the end portion 2122, and to drive the brush ring nozzle 251 to rotate until it fully enters the electronic accommodating unit 21 through the inlet and outlet 21241.

[0146] After the brush ring nozzle 251 of the brush ring nozzle assembly 25 rotates to extend out of the electronic receiving unit 21, it can spray water columns toward the inner wall of the dirt receiving cavity 11 to flush the inner wall of the dirt receiving cavity 11 and form a water seal in the dirt receiving space 111.

[0147] In this way, the brush ring nozzle assembly 25 is arranged on the toilet cover device 2, but not on the dirt receiving cavity 11 of the toilet body 1. Therefore, there is no need to open the installation hole of the brush ring nozzle assembly 25 on the dirt receiving cavity 11 of the toilet body 1, which reduces the cleaning dead corners of the inner wall of the dirt receiving cavity 11 and makes the inner wall of the dirt receiving cavity 11 easier to clean.

[0148] In an illustrative embodiment, Figure 3 As shown, the toilet cover device 2 further includes a water inlet assembly 27 , a brush ring water supply pipe 26 and a flushing water supply pipe. The water inlet assembly 27 is disposed in the installation cavity 210 of the electronic accommodating unit 21 .

[0149] The water inlet assembly 27 is provided with a water inlet 271. The water inlet 271 may extend from an opening on the bottom wall of the electronic housing unit 21. The water inlet 271 is connected to a tap water supply pipe, which can supply water to the water inlet pipe. The water inlet assembly 27 is also provided with a first water outlet and a second water outlet. A waterway is provided within the water inlet assembly 27, connecting the water inlet 271 with the first and second water outlets, respectively. Water input into the water inlet assembly 27 through the water inlet 271 can be output from the water inlet assembly 27 through the first and second water outlets. The first water outlet can be connected to the brush ring nozzle module 25 via the brush ring water supply pipe 26, and the water inlet assembly 27 can supply water to the brush ring nozzle assembly 25 through the brush ring water supply pipe 26. The second water outlet can be connected to the flushing module 241 via the flushing water supply pipe, and the water inlet assembly 27 can supply water to the flushing module 241 through the flushing water supply pipe.

[0150] A filter can also be installed within the water inlet assembly 27. This filter is located in the waterway between the water inlet 271 and the first water outlet, and is used to filter the water delivered to the brush ring nozzle assembly 25. A filter element can also be installed within the water inlet assembly 27. This filter element is located in the waterway between the water inlet 271 and the second water outlet, and is used to filter the water delivered to the flushing module 241. The flushing module 241 uses filtered water to flush the body, which is healthier.

[0151] A flush valve may also be provided in the water inlet assembly 27. The flush valve is provided on the water path between the water inlet 271 and the first water outlet, and is used to control the opening and closing of the water outlet of the brush ring nozzle assembly 25.

[0152] In this way, the water inlet assembly 27, the brush ring water supply pipe 26, and the flushing water supply pipe are centrally located within the electronic housing unit 21, making the structure of the toilet lid assembly 2 more compact, the toilet 100 more modular, and easier to install. Furthermore, the water inlet assembly 27, the brush ring water supply pipe 26, and the flushing water supply pipe are not exposed within the toilet body 1, making the toilet more neat and aesthetically pleasing.

[0153] In an illustrative embodiment, Figure 8 As shown, the electronic housing unit 21 includes a bottom shell 212 and a top cover 211. The bottom shell 212 is provided with a housing slot, the opening of which is provided at the top of the bottom shell 212. The end portion 2122 is a portion of the bottom shell 212 and is provided at the front end of the bottom shell 212.

[0154] The top cover 211 includes a cover body 2111 and a baffle 2112. The cover body 2111 is covered on the top of the bottom shell 212 and covers the opening of the receiving groove of the bottom shell 212. The cover body 2111 and the bottom shell 212 enclose the installation cavity 210. The baffle 2112 can be constructed as a flat plate. The baffle 2112 extends downward from the front end of the cover body 2111. The baffle 2112 and the cover body 2111 can be an integrally molded structure. There is no gap between the baffle 2112 and the cover body 2111. No opening is provided on the baffle 2112. The front surface of the baffle 2112 is the end face of the electronic receiving unit 21 close to the dirt receiving space 111. The baffle 2112 covers the front end face of the end portion 2122, and the lower edge of the baffle 2112 is lower than the lower edge of the front end face of the end portion 2122.

[0155] In this way, the baffle 2112 can shield the end portion 2122, preventing urine from directly falling onto the end portion 2122 and directly entering the extension opening 21231 of the end portion 2122. Furthermore, because the lower edge of the baffle 2112 is lower than the lower edge of the forward end surface of the end portion 2122, urine on the baffle 2112 does not flow along the surface of the baffle 2112 onto the end portion 2122, but instead drips directly into the waste receiving space 111. In particular, the surface of the baffle 2112 is free of any openings and is smooth, leaving no blind spots for cleaning and making it easy to clean.

[0156] The baffle 2112 is located above and behind the dirt receiving cavity 11. When the functional module 24 is retracted to the storage position of the installation cavity 210, the functional module 24 is located further back than the baffle 2112 and above the visible range of the line connecting the user's line of sight and the baffle 2112.

[0157] In the storage position, the angle between the line connecting the lowest point of the functional module 24 and the lower edge of the baffle 2112 and the horizontal plane is not less than 45°. The angle is preferably less than 30°.

[0158] When the functional module 24 is fully retracted into the installation cavity 210 of the electronic housing unit 21, the functional module 24 and the extension port 21231 will not be observed by the user. The user can only see the flat baffle 2112, which makes the overall appearance more beautiful. At the same time, it can further prevent urine from spilling into the extension port 21231 when men urinate.

[0159] In an exemplary embodiment, the electronic housing unit 21 further includes an end portion 2122. The end portion 2122 is located behind the baffle 2112. The end portion 2122 has an opening surface 2123 and a protruding opening 21231. The protruding opening 21231 is located on the opening surface 2123. When the functional module 24 is in the storage position, the end portion is substantially flush with the opening surface 2123.

[0160] When the functional module 24 is in the storage position, the end of the movable portion of the functional module 24 facing away from the installation cavity 210 is flush with the opening surface 2123 on the end 2122 of the electronic accommodating unit 21, which makes it easier for the user to clean the opening surface 2123. At the same time, the functional module 24 seals the protruding opening 21231 more tightly.

[0161] In one exemplary embodiment, the first and / or second sealing members are annular in shape. The first and / or second sealing members may be O-rings, rectangular rings, U-rings, V-rings, or Y-rings. Seal 28 is elastic. Seal 28 may be made of rubber or silicone. The rubber may be EPDM, NBR, or other rubber. Seal 28 is preferably made of a rubber with good wear resistance.

[0162] In an illustrative embodiment, Figures 35-38 As shown, the toilet 100 further includes a connection assembly 3. The connection assembly 3 includes a connection module 21 and a lifting module 32. The connection module 21 includes a positioning guide post 311. The positioning guide post 311 is connected to the rear side of the top of the toilet body 1 and extends vertically.

[0163] The bottom wall of the electron receiving unit 21 is provided with a fixing hole 2121. The fixing hole 2121 can be a through hole. The outer diameter of the positioning guide post 311 is smaller than the inner diameter of the fixing hole 2121. The positioning guide post 311 and the fixing hole 2121 of the electron receiving unit 21 are clearance-fitted.

[0164] The lifting module 32 is disposed on a side of the connecting module 21 close to the waste receiving space 111 . The lifting module is configured to lift and lower an end of the electronic receiving unit 21 close to the waste receiving space 111 .

[0165] In this way, when the gap between the front end of the electronic accommodating unit 21 and the toilet body 1 needs to be cleaned, the lifting module only needs to lift the end of the electronic accommodating unit 21 near the waste receiving space 111 to open the gap, making it easier for the user to clean the stains in the gap. After cleaning the gap, the lifting module lowers the height of the end of the electronic accommodating unit 21 near the waste receiving space 111 until the electronic accommodating unit 21 is re-covered on the toilet body 1. During this process, the positioning guide post 311 supports the electronic accommodating unit 21, preventing the electronic accommodating unit 21 from moving forward or backward to the toilet body 1.

[0166] In one exemplary embodiment, the top wall of the electron receiving unit 21 is provided with a first through hole 21111. The first through hole 21111 may be provided on the cover 2111. The bottom wall of the electron receiving unit 21 is provided with a second through hole 2120. The second through hole 2120 may be provided on the bottom housing 212. The first through hole 21111 and the second through hole 2120 are both circular holes, and are coaxially arranged between the first through hole 21111 and the second through hole 2120.

[0167] The toilet body 1 is provided with a connecting portion 12. The connecting portion 12 may be provided on the inner wall of the toilet body 1. The connecting portion 12 is provided with a mounting hole 121. The mounting hole 121 vertically passes through the connecting portion 12. The mounting hole 121 is located below the second through hole 2120 of the electronic housing unit 21.

[0168] The lifting module 32 includes a support rod 321, a knob 322, a stopper 323, and a support member 324. The support rod 321 can be configured as a straight rod with a circular cross-section. The support rod 321 has a downwardly facing bottom end with external threads. The support rod 321 extends through the first through-hole 21111 and the second through-hole 2120 in the electronic housing unit 21.

[0169] The knob 322 is disposed at the top of the support rod 321. The knob 322 is fixedly connected to the support rod 321. The position limiting member 323 is disposed on the support rod 321. The position limiting member 323 can be a retaining spring. The position limiting member 323 abuts against the bottom surface of the electronic accommodating unit 21.

[0170] The support member 324 can be configured as a rotating body. The support member 324 is provided with a third through hole 3240 and an annular groove 3244. The third through hole 3240 extends through the support member 324. The annular groove 3244 is located on the side wall of the support member 324. The annular groove 3244 is coaxial with the third through hole 3240. The third through hole 3240 is sleeved on the support rod 321. The third through hole 3240 is also provided with an internal thread, which is screwed onto the external thread of the support rod 321.

[0171] The support member 324 passes through the mounting hole 121 of the connecting portion 12. The connecting portion 12 is clamped in the annular groove 3244 of the support member 324 and cannot be separated from the annular groove 3244. The connecting portion 12 and the support member 324 have a loose fit. The connecting portion 12 and the support member 324 can be connected by a positive connection, so that the support member 324 cannot rotate relative to the connecting portion 12 in the circumferential direction of the support member 324. The connecting portion 12 supports the support member 324.

[0172] In this way, when a user rotates the knob 322 in one direction, for example, clockwise, the knob 322 causes the support rod 321 to rotate. As the support rod 321 rotates, it rises relative to the support member 324. As the support rod 321 rises, the stopper 323 causes the electronic housing unit 21 to rise synchronously. When a user rotates the knob 322 in the other direction, the knob 322 causes the support rod 321 to rotate. As the support rod 321 rotates, it descends relative to the support member 324. As the support rod 321 descends, the stopper 323 descends synchronously, and the electronic housing unit 21 descends under the action of gravity. This structure of the lifting module 32 is simple and compact, taking up little space.

[0173] In an illustrative embodiment, Figure 36 、 37 As shown, the support member 324 includes a fixing nut 3241 and a fixing plate 3242. The fixing nut 3241 includes a barrel 32411 and a first limiting portion 3242. The barrel 32411 can be configured as a cylinder. The barrel 32411 is provided with a screw hole. The screw hole can vertically penetrate the barrel 32411. The first limiting portion 3242 extends radially outward from one end of the barrel 32411. The first limiting portion 3242 can be configured as a circular ring.

[0174] The fixing plate 3242 is connected to the end of the fixing nut 3241 facing away from the first limiting portion 3242. The fixing plate 3242 may be disc-shaped. The outer diameter of the fixing plate 3242 may be the same as the outer diameter of the first limiting portion 3242, and both may be larger than the inner diameter of the mounting through hole 121 of the connecting portion 12. A fourth through hole 32421 is provided on the fixing plate 3242. The fourth through hole 32421 is coaxial with the screw hole 32413 of the cylinder 32411. The fourth through hole 32421 and the screw hole 32413 constitute the third through hole 3240 on the support member 324. The fixing plate 3242, the cylinder 32411 and the first limiting portion 3242 enclose an annular groove 3244 of the support member 324.

[0175] The screw hole 32413 of the cylinder 32411 and the fourth through hole 32421 of the fixing plate 3242 are both sleeved on the support rod 321 , and the fixing nut 3241 and the support rod 321 are threadedly connected.

[0176] The support member 324 is provided in a split type, which makes it easier to install on the connecting portion 12.

[0177] In an illustrative embodiment, Figure 4 As shown, the toilet cover device 2 further includes a decorative cover 20. The decorative cover 20 is constructed as a generally plate-shaped structure. The decorative cover 20 covers the top of the electronic housing unit 21. The decorative cover 20 and the electronic housing unit 21 are detachably connected. The decorative cover 20 at least covers the knob 322.

[0178] In this way, when the decorative cover 20 is covered on the top of the electronic accommodating unit 21, the knob 322 and other components will not be exposed, which is more beautiful. The upper surface of the decorative cover 20 is flat and easy to clean.
