Technical Field

[0001] This utility model relates to the field of toilet technology, specifically to a toilet seat assembly and a toilet. Background Technology

[0002] A toilet generally includes a ceramic tub and a toilet seat assembly mounted on the ceramic tub. The toilet seat assembly is generally made of plastic and includes a connecting seat at the rear and a cover and seat ring at the front. The cover is located above the seat ring, and the cover and seat ring are rotatably connected to the connecting seat.

[0003] A toilet seat assembly has two connecting arms fixedly connected to its cover plate. The upper wall of the connecting seat has clearance holes corresponding to the connecting arms, and a sealing ring is installed within each clearance hole. The connecting arms pass through the sealing rings, with a clearance fit to prevent the sealing rings from obstructing the movement of the connecting arms. The gap between the sealing ring and the connecting arm is generally not too small, allowing water to continuously leak into the connecting seat during toilet cleaning. Although the connecting seat has a corresponding drainage structure, continuous water inflow is clearly detrimental to maintaining a dry environment inside the connecting seat. Utility Model Content

[0004] The technical problem to be solved by this utility model is that water keeps leaking into the connecting seat when cleaning the toilet.

[0005] To solve this technical problem, this utility model provides a toilet seat assembly, including a cover plate, a connecting arm, and a connecting seat. The connecting seat includes an upper wall, and the upper wall of the connecting seat has a clearance hole corresponding to the connecting arm. One end of the connecting arm is fixedly connected to the cover plate, and the other end is rotatably connected to the connecting seat, so that the cover plate can rotate between a first position and a second position relative to the connecting seat. The connecting arm passes through the clearance hole, and a follower sealing ring is sleeved on the connecting arm. The follower sealing ring is sealed to the connecting arm and is located below the upper wall of the connecting seat. When the cover plate is in the first position, the follower sealing ring abuts against the upper wall of the connecting seat, sealing the clearance hole. When the cover plate is in the second position, the follower sealing ring separates from the upper wall of the connecting seat.

[0006] As one embodiment of this utility model, the toilet seat assembly further includes a rotating shaft, and the connecting arm includes a first part, a second part, and a third part; the first part is fixed on the cover plate and located above the upper wall of the connecting seat; the third part is located below the upper wall of the connecting seat and is rotatably connected to the connecting seat through a rotating shaft; the second part is an arc-shaped structure passing through the clearance hole, the connecting arm is clearance-fitted with the clearance hole, the second part is used to connect the first part and the third part, and the follower sealing ring is sleeved on the second part.

[0007] In one embodiment of this utility model, the follower sealing ring is sleeved on one end of the second part near the third part, and there is a corner between the second part and the third part of the connecting arm, with the follower sealing ring abutting against the corner.

[0008] As one embodiment of the present invention, the toilet seat assembly also includes a drive device, the rotating shaft being the power output shaft of the drive device, and the drive device driving the seat plate to rotate and switch between a first position and a second position via a connecting arm.

[0009] As one embodiment of this utility model, the toilet seat assembly includes two connecting arms, and the upper wall of the connecting seat is provided with two clearance holes.

[0010] In one embodiment of this utility model, the upper wall of the connecting seat includes a housing portion and a fixed sealing ring. A clearance hole is provided in the housing portion, and the fixed sealing ring is arranged around the corresponding clearance hole. The fixed sealing ring is fixedly set relative to the housing portion. The connecting arm passes through the fixed sealing ring and is in clearance fit with the fixed sealing ring. When the cover plate is in the first position, the follower sealing ring abuts against the fixed sealing ring to block the gap between the connecting arm and the fixed sealing ring, thereby sealing the clearance hole. When the cover plate is in the second position, the follower sealing ring separates from the fixed sealing ring.

[0011] In one embodiment of this utility model, the connecting seat further includes an installation compartment located below the upper wall of the connecting seat, and the connecting arm moves within the installation compartment.

[0012] In one embodiment of this utility model, the installation chamber corresponds one-to-one with the connecting arm, and the bottom of the installation chamber is provided with a drainage hole; when the cover plate is in the second position, the clearance hole and the drainage hole are connected.

[0020] The specific embodiments of this utility model will be described below with reference to the accompanying drawings and some examples.

[0021] Example 1:

[0022] See Figure 1 and 2 In this embodiment, the toilet seat assembly provided by this utility model includes a cover plate 2, a seat ring 3, two connecting arms 4, and a connecting seat 1. The connecting seat 1 includes an upper wall, and the upper wall of the connecting seat 1 is provided with clearance holes 11 corresponding to the two connecting arms 4. One end of the connecting arm 4 is fixedly connected to the cover plate 2, and the other end is rotatably connected to the connecting seat 1, so that the cover plate 2 can be in a first position relative to the connecting seat 1 (see...). Figure 2 ) and second position (see Figure 1 The connecting arm 4 rotates between the two positions. The connecting arm 4 passes through the relief hole 11, with a clearance fit to prevent interference between the hole wall and the connecting arm 4. A follower sealing ring 41 is fitted onto the connecting arm 4, and the follower sealing ring 41 is fixed to the connecting arm 4, providing a seal between them. The follower sealing ring 41 is located below the upper wall of the connecting seat 1; see [link to related document]. Figure 2 When the cover plate 2 is in the first position, the follower sealing ring 41 abuts against the upper wall of the connecting seat 1, sealing the clearance hole 11; see also Figure 1 When the cover plate 2 is in the second position, the follower sealing ring 41 separates from the upper wall of the connecting seat 1.

[0023] The toilet seat assembly also includes a pivot, and the connecting arm 4 includes a first part 42, a second part 43, and a third part 44. The first part 42 is fixed to the cover plate 2 and located above the upper wall of the connecting seat 1. The third part 44 is located below the upper wall of the connecting seat 1 and is rotatably connected to the connecting seat 1 via the pivot. The second part 43 is an arc-shaped structure passing through the clearance hole 11, and the second part 43 is used to connect the first part 42 and the third part 44. The follower sealing ring 41 is sleeved on the second part 43. In this embodiment, the toilet seat assembly is applied to a smart toilet. The toilet seat assembly also includes a drive device, and the pivot is the power output shaft of the drive device. The drive device drives the cover plate 2 to rotate and switch between a first position and a second position via the connecting arm 4. Those skilled in the art can apply the clearance hole sealing structure provided by this utility model to a conventional toilet with a clearance hole and a connecting arm as needed, which does not exceed the protection scope of this utility model.

[0024] The follower sealing ring 41 is sleeved on the end of the second part 43 near the third part 44. There is a corner between the second part 43 and the third part 44 of the connecting arm 4, and the follower sealing ring 41 abuts against the corner. In this embodiment, the follower sealing ring 41 is not only fixed by the friction between itself and the second part 43, but is also blocked by the junction of the second part 43 and the third part 44 (i.e., the aforementioned corner), preventing the follower sealing ring 41 from moving backward and affecting its sealing effect on the clearance hole 11. Those skilled in the art can also limit the follower sealing ring 41 in other ways as needed, such as by opening an annular groove on the connecting arm 4, into which the follower sealing ring 41 is inserted. When designing the limiting structure of the follower sealing ring 41, attention should be paid to the position of the follower sealing ring 41. It should not be too close to the first part 42 of the connecting arm 4, which would prevent the cover plate 2 from opening normally to the first position. Nor should it be too far away from the first part 42 of the connecting arm 4, which would prevent the follower sealing ring 41 from effectively sealing the clearance hole 11 when the cover plate 2 is in the first position.

[0025] The connecting seat 1 also includes two mounting chambers 14, each corresponding to a connecting arm 4. The mounting chambers 14 are located below the upper wall of the connecting seat 1, and the connecting arms 4 move within the mounting chambers 14 (i.e., a portion of the connecting arm 4 always remains within the mounting chamber 14). Each mounting chamber 14 has a drain hole 141 at its bottom. When the cover 2 is in the second position, the clearance hole 11 communicates with the drain hole 141. When the cover 2 is in the first position, the user can clean the toilet without worrying about water leaking into the connecting seat 1, thus preventing excessive water leakage. After cleaning the toilet, a small amount of water may remain in the clearance hole 11. Because the mounting chamber 14 has a drain hole 141 at its bottom, when the cover 2 is switched to the second position, the water in the clearance hole 11 will flow into the mounting chamber 14 and drain out through the drain hole 141, eliminating concerns about water accumulation in the connecting seat 1.

[0026] Example 2:

[0027] See Figure 3 and 4 In this embodiment, the toilet seat assembly provided by this utility model differs from that in Embodiment 1 in the following ways: the upper wall of the connecting seat 1 includes a housing portion 12 and two fixing sealing rings 13. Each fixing sealing ring 13 corresponds to a connecting arm 4. A clearance hole 11 is located in the housing portion, and the fixing sealing ring 13 is arranged around the corresponding clearance hole 11. The fixing sealing ring 13 has an opening through which the connecting arm 4 passes, and the opening communicates with the clearance hole 11. The connecting arm 4 passes sequentially through the clearance hole 11 and the opening of the fixing sealing ring 13, with a clearance fit between the connecting arm 4 and the opening of the fixing sealing ring 13. The fixing sealing ring 13 is fixedly disposed relative to the housing portion 12; see also... Figure 4 When the cover plate 2 is in the first position, the follower sealing ring 41 abuts against the fixed sealing ring 13 to seal the gap between the connecting arm and the fixed sealing ring, thereby sealing the relief hole 11 (i.e., preventing water from leaking into the connecting seat 1 from the relief hole 11); see also Figure 3 When the cover plate 2 is in the second position, the follower sealing ring 41 separates from the fixed sealing ring 13.

[0028] In this embodiment, the fixing sealing ring 13 is disposed around the corresponding relief hole 11, sandwiched between the mounting chamber 14 and the housing part 12, and located below the inner wall of the housing part 12. The opening diameter of the fixing sealing ring 13 is smaller than that of the relief hole 11. Those skilled in the art can, as needed, make the opening diameter of the fixing sealing ring 13 larger than or equal to that of the relief hole 11. Those skilled in the art can also, as needed, modify the fixing sealing ring 13 to be disposed within the relief hole 11 on the housing part 12, thereby covering the relief hole 11.
