Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a lifting structure for a toilet seat and a toilet. Background Technology

[0002] As a common piece of equipment in modern bathroom fixtures, the toilet typically consists of two main parts: the ceramic body and the toilet seat. The toilet seat includes the top cover, the seat ring, and the base. The base integrates core functional units such as the washing nozzle and the drying unit, and the toilet seat is mounted on the ceramic body. After daily use, the exposed surfaces of the ceramic body and toilet seat, being in direct contact with the external environment and having a smooth structure, can be easily cleaned with regular cleaning tools to maintain a clean appearance. However, a gap forms at the junction of the ceramic body and the toilet seat base. Due to structural design limitations, this gap easily accumulates urine, water stains, and other dirt during daily use. Because the gap is narrow and in a hidden location, regular cleaning tools cannot reach it for effective cleaning, resulting in long-term residue. This not only affects the hygiene of the bathroom environment but may also breed bacteria, posing a potential threat to the user's health. In existing technologies, the only feasible way to thoroughly clean the aforementioned gaps is to remove the entire toilet seat from the ceramic body. However, the installation and removal of the toilet seat requires specialized tools and must be carried out in strict accordance with specific steps. The process is cumbersome and time-consuming. Therefore, existing toilets have the drawback of making it difficult to clean the gaps between the ceramic body and the base of the toilet seat.

[0003] In view of the above, the designer of this utility model designed this utility model. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting structure for a toilet seat that facilitates cleaning.

[0005] Another objective of this invention is to provide a toilet structure.

[0006] To achieve the above objectives, the present invention adopts the following solution: A lifting structure for a toilet seat includes: a hydraulic power source, a seat base, and a liquid lifting device. The seat base is movably mounted on the toilet body, and the liquid lifting device is installed below the seat base. The hydraulic power source is connected to the liquid lifting device. When the liquid lifting device rises, it lifts the seat base to separate it from the toilet body; when the liquid lifting device descends, the seat base can be lowered.

[0007] In some embodiments, a switching valve is provided between the hydraulic power source and the liquid jacking device. The switching valve includes a switching body, which has an inlet water channel, at least one outlet water channel, and a lifting water channel. The lifting water channel is connected to the liquid jacking device. The switching body is provided with a movable switching element and also includes a control switch. The control switch controls the movement of the switching element, and the switching element controls the inlet water channel to selectively connect to the outlet water channel and / or the lifting water channel.

[0008] In some embodiments, the hydraulic power source includes a water supply source, and the water inlet channel of the switching valve is connected to the water supply source. When the water inlet channel is connected to the lifting water channel, the water from the water supply source can flow into the liquid lifting device through the lifting water channel, and the hydraulic pressure causes the liquid lifting device to rise, thereby lifting the cover plate base. When the water inlet channel is disconnected from the lifting water channel, the water in the liquid lifting device flows to the water outlet channel through the lifting water channel and is discharged, causing the liquid lifting device to fall, and the cover plate base can be lowered.

[0009] In some embodiments, a toilet seat lifting structure further includes a limiting mechanism, which is used to limit or release the lid base after it is raised. The limiting mechanism is located between the lid base and the toilet body and is mounted on the toilet body, the lid base, or a liquid lifting device. It also includes a limiting button. After the lid base is raised, the limiting mechanism limits the lid base, keeping it in the raised position. When the limiting button is pressed, the limiting mechanism releases the lid base, allowing the lid base to fall from the raised position to the lowered position.

[0010] In some embodiments, the limiting mechanism includes a first elastic element and a support rod. When the liquid lifting device rises, the first elastic element is released from its compressed state, causing the support rod to stand upright, thereby limiting the cover base and keeping it in the raised position. The limiting button includes a pull rope and a pull rope switch. One end of the support rod is slidably mounted on the liquid lifting device. One end of the pull rope is connected and fixed to the support rod, and the other end of the pull rope is connected and fixed to the pull rope switch. When the pull rope switch is pressed, the pull rope is pulled, pulling the support rod back to its initial position and releasing the limiting effect on the cover base. The first elastic element is compressed, and the cover base falls from the raised position to the lowered position.

[0011] In some embodiments, the limiting mechanism includes a one-way valve installed between the hydraulic power source and the liquid lifting device. When the liquid lifting device rises, the one-way valve is closed to prevent the liquid from flowing back, thereby keeping the liquid lifting device in the rising state and keeping the cover plate base in the raised position. The one-way valve is opened to allow the liquid to flow back, thereby allowing the liquid lifting device to descend and lower the cover plate base from the raised position to the lowered position.

[0012] In some embodiments, the limit button is used to control the one-way valve to open, causing the liquid lifting device to descend and thereby releasing the limit on the cover plate base, so that the cover plate base can fall from the raised position to the lowered position.

[0013] In some embodiments, the water supply source includes an external water source or a water pump, and the control switch can also control the opening and closing of the external water source, water pump, or liquid jacking device; or, it may also include a push-button switch for controlling the opening and closing of the external water source, water pump, or liquid jacking device.

[0014] In some embodiments, the liquid lifting device includes a fixed base and a hydraulic cylinder, the hydraulic cylinder having a water inlet, and the liquid lifting device further includes a piston and a second elastic element that are movably sealed and mounted inside the hydraulic cylinder, the second elastic element being disposed between the hydraulic cylinder and the piston.

[0015] A toilet includes a lifting structure for a toilet seat as described above. The toilet body has a flushing water path, a toilet bowl, and an installation chamber. The water outlet is connected to the flushing water path. The liquid lifting device is installed in the installation chamber. The water outlet of the flushing water path is located in the toilet bowl.

[0016] As can be seen from the above technical solution, this utility model solves the problem of cleaning the gap between the ceramic body of the traditional toilet and the base of the toilet seat by setting a liquid lifting device. There is no need to disassemble the toilet seat. By opening the liquid lifting device, the liquid lifting device rises and lifts the seat base to separate it from the toilet body, thus completely exposing the hidden gap between the toilet body and the seat base. At this time, cleaning tools can be easily inserted into the gap to quickly remove accumulated stains and prevent bacterial growth. When the liquid lifting device is closed, it descends and the seat base can be lowered and combined with the toilet body without affecting normal use. Compared with the traditional disassembly and cleaning method, the operation is simpler and more efficient, making cleaning more convenient. Attached Figure Description

[0035] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0036] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0037] Reference Figures 1 to 16 As shown, this utility model discloses a lifting structure for a toilet seat, including: a hydraulic power source, a seat base 1, and a liquid lifting device 4. The seat base 1 is movably installed on the toilet body 12, and the liquid lifting device 4 is installed below the seat base 1. The hydraulic power source is connected to the liquid lifting device 4. When the liquid lifting device 4 rises, it lifts the seat base 1 to separate it from the toilet body 12; when the liquid lifting device 4 falls, the seat base 1 can be lowered; wherein, the top of the liquid lifting device can abut against the lower surface of the seat base 1.

[0038] Therefore, this utility model solves the problem of cleaning the gap between the ceramic body of the traditional toilet and the base of the toilet seat by setting the liquid lifting device 4. Without disassembling the toilet seat, by opening the liquid lifting device 4, the liquid lifting device 4 rises and lifts the base of the seat 1, separating it from the toilet body 12. This completely exposes the hidden gap between the toilet body 12 and the base of the seat 1, allowing cleaning tools to easily reach into the gap and quickly remove accumulated stains, preventing bacterial growth. When the liquid lifting device 4 is closed, it descends, and the base of the seat 1 can be lowered and combined with the toilet body 12 without affecting normal use. Compared with the traditional disassembly and cleaning method, the operation is simpler and more efficient, making cleaning more convenient.

[0039] Furthermore, in the lifting structure of the toilet seat of this utility model, a switching valve 3 is provided between the hydraulic power source and the liquid lifting device 4. The switching valve 3 includes a switching body, which has a water inlet channel, at least one water outlet channel, and a lifting water channel. The lifting water channel is connected to the liquid lifting device 4. The switching body is provided with a movable switching component and also includes a control switch 2. The control switch 2 controls the movement of the switching component. The switching component controls the water inlet channel to selectively connect to the water outlet channel and / or the lifting water channel. The control switch 2 controls the movement of the switching component, thereby connecting the water inlet channel to the water outlet channel and / or the lifting water channel. When the water inlet channel is connected to the lifting water channel, the liquid lifting device 4 is activated, and the hydraulic pressure causes the liquid lifting device 4 to rise, thereby lifting the seat base 1 and separating it from the toilet body 12. The switching component can be a valve core, a rotating plate, or a switching slider.

[0040] Please see Figures 2 to 7 As shown in Embodiment 1, the lifting structure of the toilet seat of this utility model includes a hydraulic power source comprising a water supply source 10. The water inlet channel of the switching valve 3 is connected to the water supply source 10. When the water inlet channel is connected to the lifting water channel, the water flow from the water supply source 10 can flow into the liquid lifting device 4 through the lifting water channel. The hydraulic pressure causes the liquid lifting device 4 to rise, thereby lifting the seat base 1. When the water inlet channel is disconnected from the lifting water channel 10, the water supply source 10 is closed, and the water in the liquid lifting device 4 flows to the water outlet channel through the lifting water channel and is discharged, causing the liquid lifting device 4 to fall, thereby allowing the seat base 1 to be lowered.

[0041] Furthermore, the present invention may also include a limiting mechanism, which is used to limit or release the lid base 1 after it is raised. The limiting mechanism is located between the lid base 1 and the toilet body 12, and is mounted on the toilet body 12, the lid base 1, or the liquid lifting device 4.

[0042] In order to facilitate the support of the raised cover base 1, the limiting mechanism may include a first elastic element 9 and a support rod 5. When the liquid lifting device 4 rises, the first elastic element 9 is released from its compressed state to lift the support rod 5, thereby achieving the limiting effect on the cover base 1 and keeping the cover base 1 in the raised position. When the cover base 1 is lifted, the support rod 5 supports the raised cover base 1.

[0043] The support rod 5 is at least one, but not limited to this. There may also be two support rods 5, symmetrically distributed on both sides of the liquid lifting device 4. The upper end of the support rod 5 can be hinged or abutted to the lower surface of the cover plate base 1 through a rotating shaft.

[0044] Furthermore, the present invention may also include a limit button. After the cover plate base 1 is raised, the limit mechanism limits the cover plate base 1, keeping the cover plate base 1 in the raised position. When the limit button is pressed, the limit mechanism releases the limit on the cover plate base 1, thereby realizing the cover plate base 1 falling from the raised position to the lowered position.

[0045] To facilitate the release of the support rod 5 from the cover base 1, the limit button includes a pull rope 6 and a pull rope switch 7. One end of the support rod 5 is slidably mounted on the liquid lifting device 4, and the other end of the support rod 5 supports the cover base 1. One end of the pull rope 6 is connected and fixed to the support rod 5, and the other end of the pull rope 6 is connected and fixed to the pull rope switch 7. When the pull rope switch 7 is pressed, the pull rope 6 is pulled, pulling the support rod 5 back to its initial position and thus releasing the limit on the cover base 1. The first elastic element 9 is compressed, and the cover base 1 falls from the raised position to the lowered position. The pull rope 6 can be made of stainless steel wire rope to prevent corrosion and breakage.

[0046] The water supply source 10 may include an external water source or a water pump, and the control switch 2 may also control the opening and closing of the external water source, water pump or liquid lifting device 4; or, it may also include a push-button switch for controlling the opening and closing of the external water source, water pump or liquid lifting device 4.

[0047] For further information, please refer to [link / reference]. Figures 11 to 13 As shown, the liquid lifting device 4 may include a fixed base and a hydraulic cylinder. The hydraulic cylinder has a water inlet. The liquid lifting device 4 also includes a piston 45 and a second elastic element 46 that are movably sealed and installed in the hydraulic cylinder. The second elastic element 46 is disposed between the hydraulic cylinder and the piston 45.

[0048] The liquid lifting device 4 may also include a fixed column 42 and a water pipe quick connector 47. The fixed base has a fixed plate 41. The hydraulic cylinder and the water pipe quick connector 47 are installed on the fixed plate 41. The water pipe quick connector 47 is connected to the water inlet. The liquid lifting device 4 is connected to the toilet body through the fixed column 42.

[0049] To facilitate the installation of the support rod 5, the fixing plate 41 may also be provided with a receiving groove 8. The receiving groove 8 has sliding grooves 81 on both sides. The lower end of the support rod 5 is slidably disposed in the receiving groove 8. The support rod 5 and the sliding groove 81 are provided with sliding members 51. The two ends of the sliding members 51 are respectively slidably locked in the sliding groove 81. The receiving groove 8 is provided with a first elastic member 9. When the pull rope switch 7 is pressed, the pull rope 6 is pulled, the support rod 5 releases its support on the cover plate base 1, and the first elastic member 9 is compressed. When the cover plate base 1 is lifted, the first elastic member 9 elastically recovers, the support rod 5 stands up, and supports the lifted cover plate base 1.

[0050] Furthermore, the first elastic element 9 can be a spring, with one end of the first elastic element 9 fixed to the end of the receiving groove 8 and the other end connected and fixed to the support rod 5.

[0051] The hydraulic cylinder has a hydraulic cylinder body 43 and a hydraulic cylinder cover 44 that covers the hydraulic cylinder body 43. The hydraulic cylinder body, the fixing plate 41, and the fixing column 42 are integrally formed. The piston 45 is movably inserted through the hydraulic cylinder cover 44. When the switching component controls the water inlet channel to selectively connect to the lifting water channel, the water from the water supply source 10 can flow into the liquid lifting device 4 through the lifting water channel. The hydraulic pressure causes the piston 45 in the hydraulic cylinder to rise, thereby lifting the cover plate base 1. When the water inlet channel is cut off from the lifting water channel, the water in the hydraulic cylinder flows to the water outlet channel through the lifting water channel and is discharged, causing the piston 45 in the hydraulic cylinder to fall, and the cover plate base 1 can be lowered.

[0052] Please see Figure 8 A second elastic element 46 is provided between the hydraulic cylinder and the piston 45. The second elastic element 46 is used to push the piston 45 away from the hydraulic cylinder, so that it can be adapted to water pumps with low flushing pressure and has better adaptability. The second elastic element 46 can be a spring.

[0053] The water inlet channel is connected to the water supply source 10 at one end and to the inner cavity of the switching body at the other end; the water outlet channel is connected to the inner cavity of the switching body at one end and to the flushing water path of the toilet body 12 at the other end; the lifting water channel is connected to the inner cavity of the switching body at one end and to the water inlet of the hydraulic cylinder at the other end.

[0054] The water supply source 10 can use the existing water pump of the smart toilet as the water supply power source. The outlet of the water pump is connected to the water inlet channel of the switching valve 3, and its inlet is connected to the water tank of the smart toilet.

[0055] Therefore, in Embodiment 1, when it is necessary to clean the gap between the seat base 1 and the toilet body 12, the control switch 2 is pressed. The control switch 2 sends a signal to the drive mechanism of the switching component, driving the switching component to move, so that the water inlet channel is connected to the lifting water channel and disconnected from the water outlet channel; the water supply source 10 supplies water to the hydraulic cylinder through the water inlet channel and the lifting water channel, and the hydraulic pressure pushes the piston 45 to rise, lifting the seat base 1; as the seat base 1 is lifted, a cleaning gap is formed between the seat base 1 and the toilet body 12, and the cleaning gap is fully exposed; at the same time, the support rod 5 slides along the slide groove 81 under the elastic force of the first elastic element 9, and the angle between it and the seat base 1 increases until the support rod is in an inclined support state. The cover base 1 provides stable support. Pressing the control switch 2 or button switch again activates the switching element, disconnecting the inlet channel from the lifting water channel and connecting it to the outlet channel. Water in the hydraulic cylinder, under the elastic force of the second elastic element 47 and the weight of the cover itself, flows through the lifting water channel, the inner cavity of the switching valve 3, and the outlet channel into the flushing water path, ultimately draining into the toilet bowl 121. The piston 46 retracts the hydraulic cylinder body 44 as the water level drops, eliminating the need to wait for the gap between the cover base 1 and the toilet body 12 to be cleaned before controlling the liquid lifting device 4 to descend. After cleaning, pressing the pull rope switch 7 pulls the pull rope 6, overcoming the tension of the first elastic element 9 to reset the support rod 5 along the slide groove 81. Please refer to [link to relevant documentation]. Figure 4 The support on the toilet seat base 1 is released, and the toilet seat base 1 slowly falls back into the toilet body 12, returning to the usable state.

[0056] In other embodiments, while the support rod 5 is erected to support the cover plate base 1, there is no need to press the control switch 2 or the button switch to drive the switching component to move, so that the water inlet channel is disconnected from the lifting water channel and connected to the water outlet channel, so that the liquid lifting device 4 is lowered.

[0057] The elastic coefficients of the first elastic element 9 and the second elastic element 47 need to be matched according to the weight of the cover plate to ensure that the support rod 5 provides stable support and the piston resets smoothly.

[0058] See Figures 14 to 16As shown, the toilet seat base 1 and the toilet body 12 are movably mounted in the guide groove 13 via guide posts 14, allowing the toilet seat base 1 to be smoothly lifted or lowered. As shown in the figure, the guide posts 14 can be integrally formed or detachably mounted on the lower surface of the toilet seat base 1, and the guide groove 13 can be integrally formed or detachably mounted in the mounting chamber 122 of the toilet body 12, but this is not a limitation. The guide groove 13 can also be integrally formed or detachably mounted in the liquid lifting device 4. The number of guide posts 14 and the number of guide grooves 13 can be two, three, four, etc. The guide posts 14 are evenly spaced, and the guide grooves 13 are evenly spaced.

[0059] In Embodiment 2, the difference from Embodiment 1 is that the limiting mechanism includes a one-way valve 11, which is installed between the hydraulic power source and the liquid lifting device 4. When the liquid lifting device 4 rises, the one-way valve 11 is closed to prevent the liquid from flowing back, thus keeping the liquid lifting device 4 in the rising state and holding the cover plate base 1 in the raised position. When the one-way valve 11 is opened, the liquid flows back, allowing the liquid lifting device 4 to descend and lower the cover plate base 1 from the raised position to the lowered position. The one-way valve 11 is located on the water pipe connecting the liquid lifting device 4 and the water supply source 10.

[0060] In addition, in Embodiment 2, the same support rod 5 and its corresponding installation structure as in Embodiment 1 can be set, and one end of the pull rope 6 is connected and fixed to the support rod 5 and the sealing ring 114, but it can also be omitted.

[0061] The limit button is used to control the one-way valve 11 to open, so that the liquid lifting device 4 can be lowered and the limit on the cover base 1 can be released, thereby realizing the cover base 1 from the raised position to the lowered position.

[0062] Furthermore, the limit button includes a pull rope 6 and a pull rope switch 7. The one-way valve 11 has a sealing ring 114 and a sealing surface 115. One end of the pull rope 6 is connected and fixed to the sealing ring 114, and the other end of the pull rope 6 is connected and fixed to the pull rope switch 7. When the pull rope switch 7 is pressed, the pull rope 6 can pull the sealing ring 114, causing the sealing ring 114 to disengage from the sealing surface 115 and thus release the limit on the cover plate base 1, causing the liquid lifting device 4 to descend, thereby realizing the cover plate base 1 falling from the raised position to the lowered position.

[0063] like Figure 10 As shown, the end 111 of the one-way valve 11 is connected to the pull rope 6, the end 112 of the one-way valve is connected to the water supply source 10, and the end 113 of the one-way valve is connected to the hydraulic cylinder.

[0064] The sealing ring 114 of the one-way valve 11 can be made of aging-resistant rubber to avoid long-term contact with water leading to sealing failure, and the pull rope can be made of stainless steel wire rope to prevent corrosion and breakage.

[0065] Therefore, in Embodiment 2, pressing the control switch 2 controls the switching element to connect the water inlet channel and the lifting water channel; simultaneously, the control switch 2 triggers the water supply source 10 to start, and the water from the water supply source 10 enters the liquid lifting device 4 through the water inlet channel, the lifting water channel, and the one-way valve 11, pushing the piston 45 to rise and lift the cover base 1. At this time, a cleaning gap is formed between the cover base 1 and the toilet body 12, and the cleaning gap is fully exposed; after cleaning is completed, pressing the control switch 2 again triggers the pull rope 6 to pull the sealing ring 114 away from the sealing surface 115, and the one-way valve 11 opens; the water in the hydraulic cylinder flows into the toilet bowl 121 through the one-way valve 11, the lifting water channel, and the outlet channel under the action of the cover's gravity; at the same time, the water supply source 10 stops working, the switching element moves to connect the water inlet channel and the outlet channel, and the water in the liquid lifting device 4 flows to the outlet channel through the lifting water channel and is discharged, causing the liquid lifting device 4 to descend, and thus the cover base 1 can be lowered. The control switch 2 can be a push-button dual-button design, including a "lifting button" and a "flushing button": the "lifting button" is used to control the switching element and the lifting water channel to open and close, as well as the pulling of the rope, to realize the lifting and lowering of the cover; the "flushing button" is used to control the switching element and the water outlet channel to open and close, as well as the start of the flushing water path, to realize the separate flushing function; or it can adopt a single-button press duration differentiation function: pressing the control switch 2 and releasing it within the preset time of the lifting function triggers the lifting and lowering function; pressing the control switch and releasing it within the preset time of the flushing function triggers the flushing function, avoiding misoperation.

[0066] This utility model also discloses a toilet, including the lifting structure of the toilet seat. The seat base 1 and the seat body are installed on the toilet body 12. The toilet body 12 has a flushing water path, a toilet bowl 121 and an installation chamber 122. The water outlet is connected to the flushing water path. The liquid lifting device 4 is installed in the installation chamber 122. The outlet of the flushing water path can be set in the toilet bowl 121. The outlet of the flushing water path is set corresponding to the inner side wall of the toilet bowl 121 for flushing the toilet bowl.

[0067] Furthermore, the seat base 1 can be movably installed on the upper rear part of the toilet body 12 via a hinge (not shown in the figure), and the seat body (not shown in the figure) can be detachably connected to the upper surface of the seat base 1 via a snap-fit ​​structure, making it easy to remove and clean the seat body separately.

[0068] Next, the liquid lifting device 4 is fixed to the installation chamber 122, with the piston 45 facing upward and abutting against the center area of ​​the lower surface of the cover plate base 1.

[0069] The fixing plate 41 is fixed on the installation chamber 122, and the switching valve 3 is fixed on the side wall of the toilet body 12; the control switch 2 is embedded in the side of the seat base 1, and is electrically connected to the switching component drive mechanism (not shown in the figure) of the switching valve 3 through a wire, and is used to control the movement of the switching component; the switching component can also be independently controlled by an independent button switch.

The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and this invention is not limited to any specific details of these embodiments.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.

When the liquid lifting device rises, it lifts the toilet seat base to separate it from the toilet body; when the liquid lifting device descends, the toilet seat base can be lowered.

2. The lifting structure for a toilet seat as described in claim 1, characterized in that: A switching valve is provided between the hydraulic power source and the liquid lifting device. The switching valve includes a switching body, which has an inlet water channel, at least one outlet water channel, and a lifting water channel. The lifting water channel is connected to the liquid lifting device. The switching body is provided with a movable switching element and also includes a control switch. The control switch controls the movement of the switching element, and the switching element controls the inlet water channel to selectively connect to the outlet water channel and / or the lifting water channel.

3. The toilet seat lifting structure as described in claim 2, characterized in that: The hydraulic power source includes a water supply source. The water inlet channel of the switching valve is connected to the water supply source. When the water inlet channel is connected to the lifting water channel, the water from the water supply source can flow into the liquid lifting device through the lifting water channel. The hydraulic pressure causes the liquid lifting device to rise, thereby lifting the cover plate base. When the water inlet channel is disconnected from the lifting water channel, the water in the liquid lifting device flows to the water outlet channel through the lifting water channel and is discharged, causing the liquid lifting device to fall, thereby allowing the cover plate base to be lowered.

4. The lifting structure for a toilet seat as described in any one of claims 1 to 3, characterized in that: It also includes a limiting mechanism, which is used to keep the lid base in a limited position or release the limiting position after the lid base is raised. The limiting mechanism is located between the lid base and the toilet body and is mounted on the toilet body, the lid base, or the liquid lifting device. It also includes a limiting button. After the lid base is raised, the limiting mechanism limits the lid base to keep it in the raised position. When the limiting button is pressed, the limiting mechanism releases the limiting position on the lid base, thereby allowing the lid base to fall from the raised position to the lowered position.

5. The toilet seat lifting structure as described in claim 4, characterized in that: The limiting mechanism includes a first elastic element and a support rod. When the liquid lifting device rises, the first elastic element is released from its compressed state, causing the support rod to stand upright, thereby limiting the cover base and keeping it in the raised position. The limiting button includes a pull rope and a pull rope switch. One end of the support rod is slidably mounted on the liquid lifting device. One end of the pull rope is connected and fixed to the support rod, and the other end is connected and fixed to the pull rope switch. When the pull rope switch is pressed, the pull rope is pulled, pulling the support rod back to its initial position and releasing the limiting effect on the cover base. The first elastic element is compressed, and the cover base falls from the raised position to the lowered position.

6. The lifting structure for a toilet seat as described in claim 4, characterized in that: The limiting mechanism includes a one-way valve, which is installed between the hydraulic power source and the liquid lifting device. When the liquid lifting device rises, the one-way valve is closed to prevent the liquid from flowing back, thus keeping the liquid lifting device in the rising state and keeping the cover plate base in the raised position. When the one-way valve is opened, the liquid flows back, thus allowing the liquid lifting device to descend and lower the cover plate base from the raised position to the lowered position.

7. The lifting structure for a toilet seat as described in claim 6, characterized in that: The limit button is used to control the one-way valve to open, so that the liquid lifting device can be lowered and the limit on the cover plate base can be released, thereby realizing the cover plate base from the raised position to the lowered position.

8. The lifting structure for a toilet seat as described in claim 3, characterized in that: The water supply source includes an external water source or a water pump, and the control switch can also control the opening and closing of the external water source, water pump, or liquid jacking device; or, it also includes a push-button switch for controlling the opening and closing of the external water source, water pump, or liquid jacking device.

9. The lifting structure for a toilet seat as described in claim 1, characterized in that: The liquid lifting device includes a fixed base and a hydraulic cylinder. The hydraulic cylinder has a water inlet. The liquid lifting device also includes a piston and a second elastic element that are movably sealed and installed inside the hydraulic cylinder. The second elastic element is disposed between the hydraulic cylinder and the piston.

10. A toilet, characterized in that, The toilet includes a lifting structure for a toilet seat as described in claims 1 to 9, wherein the toilet body has a flushing water path, a toilet bowl, and an installation chamber, the water outlet is connected to the flushing water path, the liquid lifting device is installed in the installation chamber, and the water outlet of the flushing water path is located in the toilet bowl.
