Description

Technical Field

[0001] The utility model relates to the field of toilets, in particular to a cover plate assembly with delayed and slow rising function and a toilet. Background Art

[0002] In recent years, with the continuous improvement of people's living standards, more and more families and public places have begun to use toilets to replace the original squat toilets. As a symbol of modern life, toilets are accepted by more people. Whether in personal homes or in public places, people can feel the comfort and convenience brought by smart toilets. Some existing toilet covers have automatic flip functions, which can be realized by electric control or pure mechanical control. The structure of pure mechanical control is shown in the flip structure of a toilet cover disclosed in CN213524963U. Its defects are: the control unit needs to be manually released to flip up the cover; at the same time, the cover is easy to hit the water tank (or other components) behind it at too fast a speed after flipping up, making a loud noise and easy to be damaged. Utility Model Content

[0003] Therefore, in order to solve the above problems, the utility model provides a cover plate assembly and a toilet with delayed and slow rise.

[0004] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0005] A cover plate assembly with delayed slow rise comprises a support, a seat ring, a rotating shaft with torque and a damping structure, wherein the seat ring is assembled on the support via the rotating shaft, and the rotating shaft applies a backward torque N to the seat ring; a suction cup is provided at the bottom of the seat ring away from the seat surface, and a vacuum breaking hole is opened on the suction cup; the damping structure applies a damping force F to the relative rotation of the support and the seat ring; and the damping force F is less than the torque N.

[0006] Furthermore, the damping structure includes an elastic abutment portion and an abutment surface; the rotation of the seat ring relative to the support causes the elastic abutment portion to slide relatively on the abutment surface, and the friction force between the elastic abutment portion and the abutment surface is the damping force on the rotation of the seat ring.

[0007] Furthermore, during the rotation of the seat ring from the flat use position to the swinging backward to the upright position, the elastic abutment portion slides from the first position of the abutment surface to the second position; the abutment surface protrudes in the area close to the second position to form a buffer boss.

[0008] Furthermore, when the seat ring is driven by the rotating shaft to rise, the time for the elastic abutment to slide relatively from the first position of the abutment surface to the buffer boss is 5 seconds, and the time for the elastic abutment to slide relatively from the buffer boss position to the second position is 10 seconds.

[0009] Furthermore, the damping structure is arranged between the support and the seat ring.

[0010] Furthermore, the rotating shaft comprises a first connecting shaft, a second connecting shaft and a torsion piece connecting the first connecting shaft and the second connecting shaft. The first connecting shaft of the rotating shaft is assembled on a support, and the second connecting shaft is assembled on a seat ring.

[0011] Further, the damping structure is arranged between the first connecting shaft and the second connecting shaft; or the damping structure is arranged between the first connecting shaft and the seat ring; or the damping structure is arranged between the second connecting shaft and the support.

[0012] Furthermore, a limiting portion is also assembled on the outer peripheral wall of the second connecting shaft, and a limiting notch extending in the circumferential direction is opened on the first connecting shaft, and the limiting portion is limited within the limiting notch of the first connecting shaft; and the movable range of the limiting portion within the limiting notch matches the rotation range of the seat ring from the flat use position to the backward swing to the upright position.

[0013] Furthermore, the limiting portion is an elastic limiting portion, and a starting notch is also provided on the first connecting shaft. The elastic limiting portion can extend out of the outer peripheral wall of the second connecting shaft or retract to the outer peripheral wall of the second connecting shaft; so that the limiting portion can switch between the starting notch and the limiting notch; when the limiting portion is located in the starting notch, the torque applied by the torque member to the second connecting shaft is N1; when the limiting portion is located in the limiting notch, the torque applied by the torque member to the second connecting shaft is N2; the torque N1 is less than the torque N2.

[0014] Furthermore, the support is provided with a mounting shaft hole, the first connecting shaft is sleeved in the mounting shaft hole and forms a circumferential limit, and the second connecting shaft is exposed outside the support; the seat ring has a sleeve hole, the second connecting shaft is sleeved in the sleeve hole, and is fixed with the seat ring in the circumferential direction.

[0015] A toilet comprises a toilet seat and a cover plate assembly mounted on the toilet seat; wherein the cover plate assembly is the above-mentioned cover plate assembly with delayed slow rise; when the seat ring is in a flat use position, a suction cup is sucked onto the toilet seat by external pressure, and after the external pressure is removed, the vacuum breaking hole of the suction cup breaks the vacuum, so that the seat ring is delayed to detach and rises again under the action of the torsion of the rotating shaft and the damping force of the damping structure.

[0016] The technical solution provided by the utility model has the following beneficial effects:

[0017] 1. The seat ring is provided with a suction cup at the bottom facing away from the seat surface, and a vacuum breaking hole is opened on the suction cup; when the seat ring is in a flat use position, the suction cup is sucked onto the toilet seat by external pressure, and after the external pressure is removed, the vacuum breaking hole of the suction cup breaks the vacuum, and the vacuum breaking has a certain delay. After the user leaves, the seat ring will not flip up immediately, but will wait until the vacuum breaking is completed before automatically flipping up through the torque applied by the rotating shaft; during the process, the damping structure applies a damping force to the seat ring, so that the seat ring slowly rises and reduces the impact force with the water tank (or other components).

[0018] 2. The damping structure includes an elastic abutting portion and an abutting surface; the abutting surface protrudes in the area close to the second position to form a buffer boss; with such an arrangement, when the seat ring is about to return to its position, the elastic abutting portion abuts against the buffer boss, instantly increasing the damping force; further reducing the recovery speed of the seat ring, allowing the seat ring to slowly approach the water tank (or other components), effectively avoiding abnormal noise caused by impact, and better ensuring the service life of the product.

[0027] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0028] Embodiment 1

[0029] Reference Figures 1 to 6 As shown, the present embodiment provides a cover plate assembly with delayed slow rise, comprising a support 10, a seat ring 20, a rotating shaft 30 with torque, and a damping structure. The seat ring 20 is assembled on the support 10 through the rotating shaft 30, and the rotating shaft 30 applies a backward torque N to the seat ring 20; it refers to the torque N in the direction of flipping up to the upright position. The seat ring 20 is provided with a suction cup 21 at the bottom away from the seat surface 201, and a vacuum breaking hole 22 is opened on the suction cup 21; the damping structure applies a damping force F to the relative rotation of the support 10 and the seat ring 20; the damping force F is less than the torque N.

[0030] This embodiment also provides a toilet, including a toilet seat and a cover assembly mounted on the toilet seat; specifically, the toilet seat has a water tank structure. The cover assembly is the above-mentioned cover assembly with delayed slow rise; specifically, the support 10 has a mounting structure 12, and is mounted on the toilet seat through the mounting structure 12; the mounting structure 12 is a prior art and will not be described in detail here.

[0031] During use, an external force is applied to the seat ring 20 so that the seat ring 20 is attached to the toilet seat. At this time, the seat ring 20 is in a flat use position, and the suction cup 21 is sucked onto the toilet seat by external pressure (such as the user's gravity); when the user gets up and leaves, the rotating shaft 30 applies a backward torque N to the seat ring 20; since the suction cup 21 is still in the attracted state, the seat ring 20 can still be in a flat use position; until the vacuum breaking hole 22 on the suction cup 21 breaks the vacuum of the suction cup 21, the seat ring 20 will rebound backwards under the action of the torque N applied by the rotating shaft 30; in this way, the effect of delayed rebound can be achieved.

[0032] When the seat ring 20 rises backward, the damping structure applies a damping force F to it, which can effectively offset a part of the torque N applied by the rotating shaft 30, reduce the speed of the seat ring 20 to rise slowly, reduce the impact force with the water tank (or other components), effectively reduce abnormal noise, and protect the seat ring 20, the water tank and other components.

[0033] Further, the damping structure is arranged between the support 10 and the seat ring 20; specifically, the damping structure includes an elastic abutting portion 40 and an abutting surface 43; the elastic abutting portion 40 abuts against the abutting surface 43 by its own elastic force; the rotation of the seat ring 20 relative to the support 10 causes the elastic abutting portion 40 to slide relatively on the abutting surface 43, and the friction force between the elastic abutting portion 40 and the abutting surface 43 is the damping force F on the rotation of the seat ring 20. In this embodiment, the elastic abutting portion 40 is arranged on the support 10, specifically the side of the support 10; the abutting surface 43 is formed on the seat ring 20; of course, in other embodiments, the positions of the elastic abutting portion 40 and the abutting surface 43 can be interchanged. During the rotation process of the seat ring 20 from the flat use position to the backward swing to the upright position, the elastic abutting portion 40 slides from the first position of the abutting surface 43 to the second position.

[0034] Furthermore, the abutment surface 43 is raised in the area near the second position to form a buffer boss 44; with such an arrangement, when the seat ring 20 is about to return to its position, the elastic abutment portion 40 abuts against the buffer boss 44, instantly increasing the damping force; further reducing the recovery speed of the seat ring 20, so that the seat ring 20 slowly approaches the water tank (or other components), effectively avoiding abnormal noise caused by collision, and even avoiding collision; better ensuring the service life of the product. As in the present embodiment, the angle of the seat ring 20 in the flat use position is defined as 0°, and the angle when it returns to the final position is 90° (it may also be greater than 90°); when the seat ring recovers between 0°-80°, the elastic abutment portion 40 abuts against the abutment surface 43 to achieve a uniform and slow recovery; when it reaches the 80° position, the elastic abutment portion 40 contacts the buffer boss 44, and the elastic abutment portion 40 is compressed, which is equivalent to increasing the abutment force with the abutment surface 43, thereby greatly increasing the damping force F, which can instantly slow down the recovery speed of the seat ring 20 until it returns to the 90° position.

[0035] Specifically, in this embodiment, when the seat ring 20 is driven by the rotating shaft 30 to rise, the time for the elastic abutment portion 40 to slide relatively from the first position of the abutment surface 43 to the buffer boss 44 is 5 seconds, and the time for the elastic abutment portion 40 to slide relatively from the buffer boss 44 to the second position is 10 seconds. That is, the time taken for the seat ring 20 to rise from the 0° position to the 80° position is 5 seconds; and the time taken for the seat ring 20 to rise from the 80° position to the 90° position is 10 seconds, achieving good buffering.

[0036] Of course, in other embodiments, the recovery time of the seat ring 20 in various stages (such as the above-mentioned 0° position recovery to 80° position stage, and the 80° position recovery to 90° position stage) can be adjusted by adjusting the magnitude of the backward torque N applied by the rotating shaft 30 to the seat ring 20 and the magnitude of the damping force F applied by the damping structure to the relative rotation of the support 10 and the seat ring 20.

[0037] It should be noted that the above-mentioned torque N value and damping force F value are range values. For example, the backward torque N value applied by the rotating shaft 30 to the seat ring 20 gradually decreases during the recovery process of the seat ring 20; the damping force F value can also be adjusted by setting the abutment surface 43 to be uneven.

[0038] Specifically, the elastic abutment portion 40 includes a first spring 41 and an abutment member 42. A mounting blind hole is opened on the side of the support 10. The first spring 41 is installed in the mounting blind hole. The abutment member 42 is inserted into the mounting blind hole and abuts against the first spring 41. The first spring 41 applies an outward force to the abutment member 42 so that the abutment member 42 abuts against the abutment surface 43 of the seat ring 20.

[0039] Specifically, the rotating shaft 30 includes a first connecting shaft 31, a second connecting shaft 32, and a torsion piece 33 connecting the first connecting shaft 31 and the second connecting shaft 32. Specifically, the first connecting shaft 31 and the second connecting shaft 32 are sleeved and can rotate relative to each other; the first connecting shaft 31 and the second connecting shaft 32 enclose a mounting cavity 301, and the torsion piece 33 is a torsion spring; the torsion spring is assembled in the mounting cavity 301, and the two ends of the torsion spring are respectively restricted on the first connecting shaft 31 and the second connecting shaft 32; specifically, the first connecting shaft 31 is equipped with a first limiting piece 35, and the first limiting piece 35 forms a circumferential limit with the first connecting shaft 31; the second connecting shaft 32 is equipped with a second limiting piece 36, and the second limiting piece 35 forms a circumferential limit with the second connecting shaft 32; the first limiting piece 35 and the second limiting piece 36 are both provided with a clamping notch, and the two ends of the torsion spring are respectively restricted in the clamping notches on the first limiting piece 35 and the second limiting piece 36. In this way, the assembly of the rotating shaft 30 with torque is realized.

[0040] The support 10 is provided with a mounting shaft hole 11, and the first connecting shaft 31 is sleeved in the mounting shaft hole 11 to form a circumferential limit. Specifically, a limit rib 313 is provided on the outer circumference of the first connecting shaft 31, and a limit groove is provided on the inner wall of the mounting shaft hole 11 of the support 10. The limit rib 313 of the first connecting shaft 31 fits in the limit groove to achieve circumferential limit. The second connecting shaft 32 is exposed outside the support 10; the seat ring 20 has a sleeve hole 23, and the second connecting shaft 32 is sleeved in the sleeve hole 23 and is fixed to the seat ring 20 in the circumferential direction. Specifically, the end of the second connecting shaft 32 is provided with a limiting shaft hole 321, and also includes a fixed end cover 50, the fixed end cover 50 has a limiting shaft 51 and a plug-in portion, the fixed end cover 50 is inserted from the outside of the seat ring 20, and the plug-in portion is plugged into the seat ring 20 to form a fixed connection with the seat ring 20; the limiting shaft 51 is plugged into the limiting shaft hole 321 of the second connecting shaft 32 and forms a circumferential limit; in this way, the second connecting shaft 32 and the seat ring 20 can be circumferentially limited by subsequent assembly. Of course, in other embodiments, the above-mentioned circumferential limit structure is not limited to this, and can also be implemented in other ways.

[0041] A limiting portion 34 is also assembled on the outer peripheral wall of the second connecting shaft 32, and a limiting notch 311 extending in the circumferential direction is provided on the first connecting shaft 31, and the limiting portion 34 is limited in the limiting notch 311 of the first connecting shaft 31; and the movable range of the limiting portion 34 in the limiting notch 311 matches the rotation range of the seat ring 20 from the horizontal use position to the backward swing to the upright position; that is, when the limiting portion 34 is limited in the limiting notch 311, its movable range is the movable range of the seat ring 20 relative to the support 10.

[0042] Furthermore, the limiting portion 34 is an elastic limiting portion, and a starting notch 312 is also provided on the first connecting shaft 31. The limiting portion 34 (i.e., the elastic limiting portion) can extend out of the outer peripheral wall of the second connecting shaft 32 or retract to the outer peripheral wall of the second connecting shaft 32, so that the limiting portion 34 can switch between the starting notch 312 and the limiting notch 311; Figure 5 As shown, the limiting portion 34 is in the starting notch 312 .

[0043] When the limiting portion 34 is located in the starting notch 312, the torque applied by the torque member 33 to the second connecting shaft 32 is N1; when the limiting portion 34 is located in the limiting notch 311, the torque applied by the torque member 33 to the second connecting shaft 32 is N2; the torque N1 is less than the torque N2. If the limiting portion 34 is not assembled, the limiting portion 34 can be switched to the starting notch 312 to better prevent the torque member from torsional fatigue; specifically, the value of the torque N1 is preferably zero. When assembling, the limiting portion 34 is switched to the limiting notch 311, and the torque N2 is the torque N mentioned above.

[0044] Furthermore, the limiting portion 34 includes a second spring 342 and a limiting column 341 . The second spring 342 and the limiting column 341 are assembled on the second connecting shaft 32 . The second spring 342 applies an outward elastic force to the limiting column 341 .

[0045] Furthermore, there are two rotating shafts 30 for connecting the two sides of the seat ring 20; there are also two groups of damping structures; acting on the two sides of the seat ring 20, so that the force is more uniform.

[0046] Embodiment 2

[0047] The present embodiment provides a cover plate assembly with delayed slow rise, which is substantially the same as the structure of the first embodiment, except that: in the present embodiment, the damping structure is arranged between the first connecting shaft 31 and the second connecting shaft 32; the specific structure of the damping structure is the same as that of the first embodiment, the elastic abutment portion 40 is arranged on one of the first connecting shaft 31 and the second connecting shaft 32, and the abutment surface 43 is formed on the other. In this way, the damping force F can also be applied to the relative rotation of the support 10 and the seat ring 20.

[0048] Of course, in other embodiments, the damping structure may also be disposed between the first connecting shaft 31 and the seat ring 20, or between the second connecting shaft 32 and the support 10. In this way, as long as the damping force F can be applied to the relative rotation between the support 10 and the seat ring 20, it will suffice.
