Description

Technical Field

[0001] The present invention relates to the technical field of intelligent toilet seats, and particularly to a toilet seat cover with flip limit and an intelligent toilet. Background Art

[0002] With the continuous progress of the Internet of Things and intelligent bathroom products, intelligent toilets have triggered a bathroom revolution. They have many advantages such as technology, convenience, and hygiene, and have become the future development trend of bathrooms.

[0003] Intelligent toilets usually have the functions of automatic lid flipping and seat ring flipping. In the existing lid flipping and seat ring flipping designs, in order to ensure the vertical stability of the toilet lid and seat ring after being opened, there are certain requirements for the flipping angle. For example, the gearbox model needs to be greater than 95°, and the slow-falling model even needs to be greater than 98°. However, due to space limitations, the flipping angle often cannot meet the design requirements, which may cause the toilet lid and seat ring to not be able to maintain a stable vertical state after being opened, or even close the lid. Summary of the Invention

[0004] To solve the above technical problem that the existing toilet seat cover may not be able to maintain a stable vertical state after being opened, the present invention provides a toilet seat cover with flip limit, which includes a rear cover, a seat ring, and a limit component.

[0005] The seat ring has a first hinge. One end of the first hinge is a fixing part for fixing on the seat ring, and the other end of the first hinge is a hinge part hinged to the rear cover. The fixing part is connected to the hinge part through a connecting part, so that the seat ring can be flipped relative to the rear cover. The limit component is arranged on the rear cover, and the limit component is on the movement track of the connecting part. When the seat ring is flipped to a preset angle, the limit component abuts against the connecting part to achieve limit.

[0006] Further, the limit component has a limit arm. A first limit structure is arranged on one side of the connecting part facing the limit component, and a first limit matching structure is arranged on the limit arm. When the seat ring is flipped to a preset angle, the first limit structure and the first limit matching structure are engaged to achieve limit.

[0007] Further, the first limit structure is a limit groove, and the first limit matching structure is a convex block protruding from the limit arm towards the first hinge.

[0008] Further, the limit component includes a limit main body and a hollow cavity in the middle area of the limit main body. The limit arm is arranged on the side surface of the limit main body facing the connecting part and adjacent to the hollow cavity, so as to allow the limit arm to be compressed and deformed into the hollow cavity when subjected to an external force.

[0009] Further, the toilet seat cover with flip limit further includes an upper cover, and a second hinge is provided on the upper cover. The second hinge is hinged to the rear cover and is movably connected to the rear cover. The limiting component is located on the movement track of the second hinge. When the upper cover is flipped to a preset angle, the second hinge abuts against the limiting component to realize the limit of the upper cover.

[0010] Further, the toilet seat cover with flip limit further includes a first electrode and a second electrode. The first electrode is arranged on the first hinge, and the second electrode is arranged on the limiting component. When the seat ring is not flipped, the first electrode is electrically connected to the second electrode.

[0011] Further, a heating component is arranged in the seat ring, and the heating component is electrically connected to the first electrode, so that the seat ring has a heating function.

[0012] Further, the toilet seat cover with flip limit further includes a locking component, and the locking component is arranged on the rear cover for fixing and detaching the toilet seat cover with flip limit from the toilet body.

[0013] Further, a third electrode is further arranged on one side of the first hinge facing the limiting component. When the seat ring is opened to a specific angle and the third electrode is electrically connected to the second electrode and the conduction time exceeds a preset threshold duration, the locking component is driven to automatically release the toilet seat cover with flip limit to realize quick detachment.

[0014] Further, the present invention also provides an intelligent toilet, including the toilet seat cover with flip limit according to any one of the above.

[0015] Based on the above, for the toilet seat cover with flip limit and the intelligent toilet provided by the present invention, compared with the prior art, by arranging a limiting component on the rear cover, the limiting component has a limiting arm. When the seat ring is opened to a preset angle, the limiting arm abuts against the first hinge of the seat ring to realize the limit. In the case of insufficient flip angle of the cover, it can avoid the problem that the seat ring and the toilet seat cover cannot be kept upright and may fall, thus improving the use experience.

Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more. Additionally, the term "comprising" and any of its variations mean "including at least".

[0021] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of a toilet seat cover with flip limit provided by an embodiment of the present invention; Figure 2 which is an exploded structural diagram of a toilet seat cover with flip limit provided by an embodiment of the present invention.

[0022] To solve the above technical problem that the existing toilet seat cover may not be able to stably maintain an upright state after being opened, or to achieve at least one of the above advantages or other advantages, an embodiment of the present invention provides a toilet seat cover with flip limit. As shown in the figure, the toilet seat cover with flip limit includes a rear cover 10, a seat ring 20, and a limit assembly 30.

[0023] The rear cover 10 provides a basic installation and support structure for the seat ring 20 and the limit assembly 30, and a central control module (not shown in the figure) of the intelligent toilet can be installed in the rear cover 10 to achieve intelligent control. In specific implementation, the rear cover 10 is installed at the rear part of the top of the toilet. Preferably, the rear cover 10 can be made of water-resistant plastic. Of course, the rear cover 10 can be injection-molded or sintered, or made by other preparation processes and materials, which will not be elaborated here.

[0024] The seat ring 20 can also be made of water-resistant plastic. Of course, the manufacturing materials and manufacturing methods of the rear cover 10 and the seat ring 20 are all existing technical solutions, and this case does not make requirements on them, and can be selected according to actual production needs.

[0025] The seat ring 20 is provided with a first hinge 21. The first hinge 21 is hinged to the rear cover 10 so that the seat ring 20 can be turned relative to the rear cover 10 around the fixed axis of the first hinge 21. Specifically, one end of the first hinge 21 is a fixing part 211 for fixing on the seat ring 20, and the other end is a hinged part 212 hinged to the rear cover 10. The fixing part 211 is connected to the hinged part 212 through a connecting part 213 to realize the turning of the seat ring 20. Specifically, existing slow-falling mechanisms and rotating shafts and other movable structures can be used to achieve this.

[0026] Please combine Figure 2 Refer to Figure 3 , Figure 4 and Figure 5 , the limiting component 30 is arranged on the rear cover 10. Taking the illustration as an example, from the perspective of the limiting component 30 facing the first hinge 21, the limiting component 30 is on the movement track of the connecting part 213. When the seat ring 20 is turned to a preset angle, the limiting component 30 abuts against the connecting part 213 to realize limiting.

[0027] Specifically, when the seat ring 20 is in the initial state (covered on the toilet and not turned up), the connecting part 213 and the limiting component 30 do not abut against each other. When the seat ring 20 is turned upwards to the preset angle, the connecting part 213 abuts against the limiting component 30, and the limiting component 30 applies a force to the connecting part 213 to realize limiting. This avoids wear on the limiting component 30 caused by the turning movement of the seat ring 20.

[0028] Preferably, the connection between the first hinge 21 and the rear cover 10 is detachable, which is convenient for the installation and disassembly of the seat ring 20.

[0029] It can be understood that the "preset angle" described in the above embodiments can be adjusted according to the shape, size, and limited installation space of the actual toilet used.

[0030] By arranging the limiting component 30 on the rear cover 10 and using the mechanical interference between the limiting component 30 and the first hinge 21, it is avoided that the turning angle of the seat ring 20 is limited by the space and cannot reach the designed angle, resulting in the problem that it cannot maintain an upright state and automatically falls. This solution has a simple structure and is easy to implement, without changing the original hinge structure.

[0031] In a preferred embodiment, one side of the limiting component 30 facing the first hinge 21 can have a limiting arm 31. When the seat ring 20 is turned upwards to the preset angle, the connecting part 213 abuts against the limiting arm 31, and the limiting arm 31 undergoes elastic deformation under force and applies a reaction force to the connecting part 213 to realize the limiting of the seat ring 20. The design of the limiting arm 31 can improve the accuracy of the preset angle, improve the durability of the limiting component 30, and avoid the failure of the limiting function caused by long-term wear.

[0032] On the basis described above, a first limiting structure 214 is provided on one side of the connecting portion 213 facing the limiting component 30. A first limiting and mating structure 311 is provided on the limiting arm 31. When the seat ring 20 is flipped to a preset angle, the first limiting structure 214 abuts against the first limiting and mating structure 311 to achieve limiting.

[0033] Specifically, the first limiting structure 214 and the first limiting and mating structure 311 are configured as complementary geometric structures, such as a combination of a limiting block and a limiting groove, or a cooperation between a protrusion and a depression. And the spatial position relationship between the first limiting structure 214 and the first limiting and mating structure 311 is set such that when the seat ring 20 is opened to the preset angle, the two are mutually engaged.

[0034] Taking the first limiting structure 214 as a limiting groove and the first limiting and mating structure 311 as a convex block protruding from the limiting arm as an example, when the seat ring 20 is flipped upward, the connecting portion 213 drives the first limiting structure 214 to move synchronously. When the seat ring 20 is flipped to the preset angle, the first limiting structure 214 and the first limiting and mating structure 311 are mutually engaged and abutted to generate a force to limit the rotation of the seat ring 20, achieve limiting, and prevent the seat ring 20 from falling.

[0035] Preferably, the limiting component 30 includes a limiting main body 32 and a hollow cavity 33 located in the middle region of the limiting main body 32. The limiting arm 31 is located on the side surface of the limiting main body 32 facing the connecting portion 213 and is adjacent to the hollow cavity 33, so as to allow the limiting arm 31 to be compressed and deformed into the hollow cavity 33 under the action of an external force, which can improve the durability of the limiting component 30, prevent the limiting function from failing due to long-term wear, and also facilitate the limiting component 30 to be used as a separate component and assembled to the corresponding position of a traditional toilet or an existing toilet at home, and can also avoid the problem of the toilet lid automatically falling, and has good versatility, compatibility and practicability.

[0036] In some preferred embodiments, the toilet lid with flip limiting further includes an upper cover 40. In the initial state (closed on the toilet and not flipped up), the upper cover 40 is located above the seat ring 20.

[0037] Specifically, a second hinge 41 is provided on the upper cover 40. The second hinge 41 is hinged to the rear cover 10 so that the upper cover 40 can be flipped relative to the rear cover 10. Preferably, the second hinge 41 and the rear cover 10 are detachably connected, which is convenient for the installation and disassembly of the upper cover 40.

[0038] Further, the limiting component 30 can be arranged between the first hinge 21 and the second hinge 41, and the limiting component 30 is also on the movement track of the second hinge 41. When the upper cover 40 is flipped to a preset angle, the second hinge 41 abuts against the limiting component 30 to achieve limiting, which is convenient for limiting the upper cover 40 when the upper cover 40 is opened separately, and avoids the problem that the upper cover 40 automatically falls.

[0039] Preferably, taking the illustration as an example, when viewed from the side, the movement tracks of the second hinge 41 and the first hinge 21 coincide with each other, which can reduce the space occupation, and when the seat ring 20 is flipped upward, the upper cover 40 can be driven to flip upward synchronously.

[0040] When the seat ring 20 is flipped to a preset angle, the connecting portion 213 abuts against the limiting arm 31 to achieve limiting. At this time, the upper cover 40 is located on the side of the seat ring 20 facing the rear cover 10. While the seat ring 20 remains upright, the upper cover 40 is forced to remain upright as well, avoiding the problem of automatic falling.

[0041] In another specific embodiment, as Figure 6 shown, the toilet seat cover with flip limiting can include a first electrode 50 and a second electrode 60.

[0042] Specifically, when implemented, the first electrode 50 is arranged on the first hinge 21 and is located on the side facing the limiting component 30. The first hinge 21 can be a hollow structure for arranging the relevant wire harnesses of the first electrode 50.

[0043] The second electrode 60 is arranged on the limiting arm 31 and is located on the side facing the first hinge 21. Relevant wire harnesses can be buried in advance in the limiting component 30 to electrically connect the second electrode 60 to components such as an external power source or a central control module. When the seat ring 20 is not opened, the first electrode 50 is in contact with the second electrode 60 to conduct, for realizing intelligent control functions such as the electrical conduction of the seat ring 20 or the detection of the opening and closing state.

[0044] Preferably, the contact surfaces of the first electrode 50 and the second electrode 60 can be designed as a concave-convex matching structure. For example, the first electrode 50 has a spherical protrusion, and the second electrode 60 has a corresponding groove, so as to enhance the conduction stability. The conduction resistance of the first electrode 50 and the second electrode 60 can be controlled within the range of 0.5 - 2Ω to ensure the reliability of signal transmission.

[0045] On the basis described above, a heating component (not shown in the figure) may be provided inside the seat ring 20. The heating component may be one or more of an electric heating wire, a graphene heating film, or a carbon limit heating sheet, and is integrated into the internal sandwich structure of the seat ring 20. The heating component is electrically connected to the first electrode 50, enabling the seat ring 20 to have a heating function. When the seat ring 20 is turned upwards, the first electrode 50 is disengaged from the second electrode 60, the heating component is powered off to save energy, and it can also play a role in power-off protection.

[0046] Of course, it is also possible to control the turning on and off of other intelligent functions such as lighting and deodorization through the conduction and disconnection of the electrical connection signal between the first electrode 50 and the second electrode 60.

[0047] In some preferred embodiments, as Figure 7 shown, the toilet seat with flip limit also includes a locking component 70. The locking component 70 is provided on the rear cover 10. Through the locking component 70, the toilet seat with flip limit can be fixed to or detached from the toilet body.

[0048] The locking component 70 can be a conventional adjustable or releasable mechanical structure, such as a buckle, a slide rail, or an elastic locking mechanism, etc. The connection position of the locking component 70 to the rear cover 10 can be adaptively designed according to the main structure of the toilet seat with flip limit to avoid interfering with the movement space of the seat ring 20 or the upper cover 40. The movable connection between the locking component 70 and the rear cover 10 realizes state switching through mechanical linkage. For example, the elastic bolt retracts and releases when pressed, and pops out and locks when reset.

[0049] Specifically, the locking component 70 forms a temporary fixation between the rear cover 10 and the toilet body through a detachable connection method. When it is necessary to disassemble the toilet seat with flip limit, by triggering the release mechanism of the locking component 70, such as pressing the elastic bolt or sliding the unlocking buckle, the physical constraint between the toilet seat with flip limit and the toilet body is released. At this time, the toilet seat with flip limit can be detached from the toilet body along a preset trajectory.

[0050] During installation, align the toilet seat with flip limit and push it in, and the locking component 70 automatically completes the clamping and locking. The whole process does not require tool assistance, and the operation path is independent of the flip trajectory of the seat ring 20. Through the locking component 70, the quick installation and disassembly of the toilet seat with flip limit can be realized.

[0051] On the basis described above, in order to achieve intelligent automatic judgment of the release and attachment of the attachment component 70, a third electrode 80 may also be provided on the side of the first hinge 21 facing the limit component 30. When the seat ring 20 is turned upward and the conduction time between the third electrode 80 and the first electrode 50 exceeds the preset threshold duration, the attachment component 70 can be automatically released by the motor 71 to drive the toilet cover with flipping limit, so as to achieve intelligent control.

[0052] During specific implementation, the third electrode 80 is arranged on the surface of the first hinge 21 close to the limit component 30, and is arranged at intervals along the setting direction of the first hinge 21 with respect to the first electrode 50. So that when the seat ring 20 is turned to a specific angle, the third electrode 80 can be in contact and conduction with the second electrode 60. When the conduction duration reaches the preset threshold duration, the attachment component 70 is driven by the motor 71 to trigger the release of the attachment. This can prevent the toilet cover with flipping limit from being accidentally triggered to separate from the toilet body during the flipping process of the seat ring 20. Preferably, the preset threshold duration is not less than 5S.

[0053] Of course, the specific angle of the seat ring 20 when the third electrode 80 and the second electrode 60 are in conduction and the preset threshold duration can be adjusted according to the specific toilet applied and the usage requirements, and all are within the protection scope of this application.

[0054] In some preferred embodiments, the present invention also provides an intelligent toilet, including the toilet cover with flipping limit according to any one of the above.

[0055] To sum up, the toilet cover with flipping limit and the intelligent toilet provided by the present invention, compared with the prior art, by arranging a limit component on the rear cover, the limit component has a limit arm, when the seat ring is opened to a preset angle, the limit arm abuts against the first hinge of the seat ring to achieve limit, in the case of insufficient flipping angle, it can prevent the seat ring and the toilet cover from being unable to stand upright, which may cause the problem of falling, and improves the user experience.

[0056] Although terms such as limit component and limit arm are used more frequently in this article, the possibility of using other terms is not excluded. These terms are only used to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0057] In addition, those skilled in the art should understand that although there are many problems in the prior art, each embodiment or technical solution of the present invention can be improved only in one or several aspects, and it is not necessary to solve all the technical problems listed in the prior art or the background art at the same time. Those skilled in the art should understand that the content not mentioned in a claim should not be regarded as a limitation to that claim.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention.
