Description

Technical Field

[0001] This application relates to, but is not limited to, the field of toilet equipment technology, specifically referring to a toilet. Background Technology

[0002] As society ages, the toilet needs of the elderly are receiving increasing attention. The elderly and those with mobility issues often have limited physical mobility, requiring them to bend over to adjust their center of gravity when sitting down and to use the toilet for support when standing up, which poses safety hazards such as slipping and bumping. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a toilet that helps to solve the safety hazards caused by the difficulty for the elderly or other users with mobility impairments to sit down or get up when using the toilet.

[0004] This application provides a toilet, including: a toilet body with a toilet bowl and a sewage discharge channel communicating with the toilet bowl; a toilet base located below the toilet body; and a lifting system connected to the toilet body and supported on the toilet base, configured to drive at least a portion of the toilet body to move up and down relative to the toilet base, so that the toilet body can switch from an initial state to an inclined state; wherein, in the inclined state, the rear of the toilet body is higher than the front of the toilet body; and the height difference between the rear and front of the toilet body tends to increase when switching from the initial state to the inclined state.

[0005] When a user uses the toilet, the lifting system raises or lowers at least part of the toilet body, switching the toilet body from its initial state to a tilted state where the rear is higher than the front. The toilet tilts forward at a preset height, which is suitable for the physical characteristics of the elderly and users with mobility difficulties. When sitting down, the tilted posture reduces the difficulty of bending over and exerting force. When getting up, the tilted posture provides upward support and assistance, effectively reducing the risk of loss of balance.

[0021] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0022] like Figures 1-8 As shown in the figure, this application embodiment provides a toilet, including: toilet body 1, lifting system 2 and toilet base 4.

[0023] The toilet body 1 has a bowl 111 and a sewage discharge channel communicating with the bowl 111. The toilet base 4 is located under the toilet body 1. The lifting system 2 is connected to the toilet body 1 and supported by the toilet base 4, and is configured to drive at least a part of the toilet body 1 to move up and down, so that the toilet body 1 can switch from the initial state to the tilted state. In the tilted state, the rear of the toilet body 1 is higher than the front of the toilet body 1, and the height difference between the rear and front of the toilet body 1 tends to increase when switching from the initial state to the tilted state.

[0024] In this way, when elderly or mobility-impaired users use the toilet, the lifting system 2 can drive at least part of the toilet body 1 to rise and fall, so that the toilet body 1 switches from the initial state to an inclined state where the rear is higher than the front. This makes it easier for these users to sit down by relying on the inclined posture to reduce the difficulty of bending over and exerting force, and to get up by using the inclined posture to provide upward support. This effectively reduces the risk of loss of balance and makes it easier for users to sit down and get up. This helps to improve the safety and convenience of elderly or mobility-impaired users in using the toilet, and helps to avoid safety hazards such as slipping and bumping during the toilet use process.

[0025] The tilting state of the toilet body 1 can be achieved through partial lifting and lowering, either by raising the rear or lowering the front separately, or by raising and lowering the toilet body 1 as a whole first, followed by raising or lowering the rear or front separately. During the transition from the initial state to the tilted state, the height difference between the rear and front of the toilet body 1 increases. This can be achieved by continuously increasing the height difference through partial lifting and lowering from the start of the transition; or by first raising and lowering the entire body to a preset height, maintaining the rear or front height position unchanged, and then increasing the height difference by raising or lowering the rear separately. The increase in height difference can be gradual or incremental.

[0026] In some exemplary embodiments, such as Figure 7 , Figure 19 As shown, the toilet body 1 includes: a toilet base 11, a waste disposal device 12, a brush ring assembly 13, and a toilet seat 14. The toilet base 11 has a bowl 111 and a brush ring outlet 113 connected to the bowl 111, and a brush ring assembly 13 is provided at the brush ring outlet 113. When flushing, the brush ring assembly 13 can spray water onto the inner wall of the toilet bowl 111, especially the area corresponding to the brush ring at the top of the bowl 111, forming a 360° or targeted flushing trajectory to wash away waste.

[0027] like Figures 19-22As shown, the sewage discharge device 12 includes a sewage discharge box 121 and a sewage discharge pipe 122 located at least partially within the sewage discharge box 121. The sewage discharge box 121 is fixedly connected to the toilet base 11. The sewage discharge pipe 122 communicates with the toilet bowl drain outlet 112 and is rotatable relative to the sewage discharge box 121 between an initial position and a sewage discharge position. The sewage discharge box 121 is provided with a sewage discharge outlet 1211 that communicates with an external sewage pipe. The toilet bowl drain outlet 112, the sewage discharge box 121, and the sewage discharge pipe 122 constitute a sewage discharge channel.

[0028] In this way, the sewage discharge device 12 uses inertia and gravitational potential energy to discharge the sewage in the sewage pipe 122, realizing the flip-over sewage discharge. Compared with the traditional siphon sewage discharge method, the flip-over sewage discharge method can eliminate the jet nozzle at the bottom of the toilet bowl, thereby avoiding the noise generated by the jet nozzle at the bottom of the toilet body 1 and the siphon sewage discharge.

[0029] In some exemplary embodiments, from the initial position to the discharge position, the discharge pipe 122 rotates toward the first cross arm assembly 231 of the lifting system 2 described below. This reduces the rotation range of the discharge pipe 122, and allows the discharge box 121 to be configured as an irregular structure with left and right asymmetry, which helps to reduce the volume of the discharge box 121, so as to hide the discharge device 12 inside the lifting system 2.

[0030] In some exemplary embodiments, the toilet also includes a displacement device 15, which is located within the toilet base 4. The inlet of the displacement device 15 is connected to the sewage outlet 1211. The outlet of the displacement device 15 is configured to connect to an external sewage pipe. The displacement device 15 is provided with a telescopic pipe to make the distance between the inlet and outlet of the displacement device 15 adjustable, adapting to different pipe installation positions to ensure smooth sewage discharge.

[0031] In some exemplary embodiments, such as Figures 1-7 As shown, the toilet also includes a toilet shell 3. The toilet shell 3 is connected to the toilet body 1, and at least a portion of the toilet body 1 is located inside the toilet shell 3. A toilet base 4 is located below the toilet body 1 and is fitted inside the toilet shell 3; the lifting system 2 is supported by the toilet base 4.

[0032] In this way, the toilet shell 3 is connected to the toilet body 1 and houses at least part of it, and the toilet base 4 is fitted inside the toilet shell 3 and supports the lifting system 2, thus achieving a compact structural layout. The toilet shell 3 protects the toilet body 1 and the inner lifting system 2, and the toilet base 4 provides stable support for the lifting system 2.

[0033] In some exemplary embodiments, such as Figure 7 and Figure 19As shown, the toilet base 11 includes a base body 114 and a fixing bracket 115. The base body 114 has a toilet bowl 111 and a brush ring outlet 113, and is connected to the toilet seat 14 and the lifting system 2. The fixing bracket 115 is fixedly connected to the base body 114, for example, by multiple fasteners. The fixing bracket 115 is fixedly connected to the toilet shell 3. In some exemplary embodiments, such as... Figure 24 As shown, the toilet base 4 has an installation cavity 41, and the lifting system 2 is at least partially located in the installation cavity 41. The shape of the toilet base 4 is adapted to the shape of the toilet shell 3, wherein the size of the toilet base 4 is slightly smaller than that of the toilet shell 3.

[0034] In this way, the concealed design of the toilet shell 3 and the slightly smaller toilet base 4 fitted inside it allows the lifting system 2 to be hidden between the toilet base 4 mounting cavity 41 and the toilet shell 3 when it is raised or lowered, so that its structure is not exposed. The toilet body 1 is at least partially housed inside the toilet shell 3. This not only greatly enhances the cleanliness and utilization of space and realizes the dynamic display of the lifting function (the lifting action is only triggered when in use), but also minimizes the risk of other objects entering the lower space of the toilet during the lifting and lowering process, causing accidental bumps and damage, through the double-layer protective structure of the shell and the base. At the same time, the unified shape design ensures the overall aesthetics, taking into account both the safety of use and the visual integrity.

[0035] In some exemplary embodiments, the fixing bracket 115 is an annular bracket arranged circumferentially along the upper opening of the toilet shell 3. One of the fixing bracket 115 and the toilet shell 3 is provided with a plurality of buckles 1151 spaced apart circumferentially along the fixing bracket 115, and the other is provided with a plurality of locking holes 31. The plurality of buckles 1151 are inserted one by one into the corresponding locking holes 31, so that the fixing bracket 115 and the toilet shell 3 are engaged. In this embodiment, the fixing bracket 115 is provided with a plurality of buckles 1151 spaced apart circumferentially, and the toilet shell 3 is provided with a plurality of locking holes 31, with the plurality of buckles 1151 inserted one by one into the corresponding locking holes 31.

[0036] In some exemplary embodiments, the fixing bracket 115 is fixedly connected to the toilet housing 3 by a plurality of fasteners spaced circumferentially along the opening at the upper end of the toilet housing 3. This ensures the reliable connection between the fixing bracket 115 and the toilet housing 3.

[0037] In some exemplary embodiments, such as Figures 8-13As shown, the lifting system 2 includes an upper support 21, a lower support 22, a lifting assembly 23, and a drive device 24. The lifting assembly 23 is connected to the upper support 21, the lower support 22, and the drive device 24, and is configured to drive the upper support 21 relative to the lower support 22 under the drive of the drive device 24, allowing the upper support 21 to switch to an inclined state with a lower front and a higher rear. The upper support 21 is connected to the toilet body 1 and is configured to drive at least a portion of the toilet body 1 to perform lifting movements, allowing the toilet body 1 to switch from an initial state to an inclined state.

[0038] In this way, after the drive device 24 is started, it can drive the lifting component 23 to move. The lifting component 23 drives the upper bracket 21 to move relative to the lower bracket 22, so that the upper bracket 21 switches to an inclined state with the front lower and the back higher. The upper bracket 21 connected to the toilet body 1 synchronously drives the toilet body 1 to at least partially complete the lifting movement, so that the toilet body 1 switches from the initial state to an inclined state with the back higher than the front.

[0039] In some exemplary embodiments, the lifting assembly 23 includes: a first crossarm assembly 231 and a second crossarm assembly 232 arranged side by side. The first crossarm assembly 231 includes a first cross subarm 2311 and a second cross arm 2312 that are cross-arranged and rotatably connected, and the second crossarm assembly 232 includes a third cross subarm 2321 and a fourth cross arm 2322 that are cross-arranged and rotatably connected, such as... Figure 14 As shown. When the toilet body 1 is in its initial state, the first cross arm 2311 and the third cross arm 2321 are arranged parallel and spaced apart, and the second cross arm 2312 and the fourth cross arm 2322 are also arranged parallel and spaced apart. The upper ends of the first cross arm 2311 and the third cross arm 2321 are rotatably connected to the upper bracket 21, and the lower ends of the first cross arm 2311 and the third cross arm 2321 are slidably connected to the lower bracket 22. The upper ends of the second cross arm 2312 and the fourth cross arm 2322 are also slidably connected to the upper bracket 21, and the lower ends of the second cross arm 2312 and the fourth cross arm 2322 are rotatably connected to the lower bracket 22. The upper bracket 21 has two parallel and spaced first slide rails 211, and the upper ends of the second cross arm 2312 and the fourth cross arm 2322 respectively slide in engagement with the corresponding first slide rails 211.

[0040] Thus, with the first crossarm assembly 231 and the second crossarm assembly 232 arranged side by side, and each crossarm connected to the upper support 21 and the lower support 22 using a combination of rotatable and sliding connections, the upper end of the first crossarm assembly 231 can be raised or lowered by driving the upper end of the first crossarm 2311 to rotate, or the lower end of the first crossarm 2311 to slide, or the upper end of the second crossarm 2312 to slide, or the lower end of the second crossarm 2312 to rotate. Similarly, the upper end of the second crossarm assembly 232 can be raised or lowered by driving the upper end of the third crossarm 2321 to rotate, or the lower end of the third crossarm 2321 to slide, or the upper end of the fourth crossarm 2322 to slide, or the lower end of the fourth crossarm 2322 to rotate. The lifting and lowering movements of the upper end of the first cross arm assembly 231 and the upper end of the second cross arm assembly 232 can drive the lifting and lowering movements of the upper bracket 21, thereby realizing the lifting and lowering movements of the toilet body 1.

[0041] Using two sets of parallel cross arm assemblies as the lifting assembly 23 has the advantages of small space occupation and good support stability. It not only makes it easy to hide the structure of the toilet body 1 inside the lifting assembly 23, but also helps to improve the lifting stability of the toilet body 1.

[0042] In other embodiments, the lifting assembly 23 is not limited to a crossarm assembly; other equivalent structures capable of partially or entirely lifting the toilet body 1 can also be used. For example, the lifting assembly 23 includes a base, an upper support 21, a motor, multiple screws, a drive gear, a driven gear, and a conveyor belt. The base has screw holes that are screwed into the screws one by one. The upper end of the screw is connected to the upper support and fitted with a driven gear. The motor output shaft is fitted with a drive gear. The drive gear is linked to all the driven gears through the conveyor belt. The motor drives the drive gear to rotate, which in turn drives all the driven gears and screws to rotate synchronously via the conveyor belt. The screws screw in or out relative to the screw holes, thereby driving the upper support 21 and the toilet body 1 above to rise and fall. The lifting assembly 23 can also be a multi-link linkage assembly, a telescopic push rod assembly, a screw and nut transmission assembly, a hydraulic telescopic assembly, a pneumatic lifting assembly, a gear and rack transmission assembly, or a combination thereof.

[0043] In some exemplary embodiments, the first cross arm assembly 231 and the second cross arm assembly 232 are spaced apart along the width direction (i.e., the left-right direction) of the toilet body 1. The first slide rail portion 211 includes a straight section 2111 and a curved section 2112 that are connected to each other. When the upper ends of the second cross arm 2312 and the fourth cross arm 2322 slide to the straight section 2111, the toilet body 1 is in the initial state; when the upper ends of the second cross arm 2312 and the fourth cross arm 2322 slide to the curved section 2112, the toilet body 1 is in an inclined state.

[0044] During the movement of the first cross arm assembly 231, the upper end of the first cross sub-arm 2311 remains flush with the upper end of the second cross sub-arm 2312. During the movement of the second cross arm assembly 232, the upper end of the third cross sub-arm 2321 remains flush with the upper end of the fourth cross sub-arm 2322. Therefore, if the first slide rail portion 211 only includes the straight section 2111, the upper bracket 21 and the toilet body 1 will continue to rise and fall in their initial state. However, in this design, the first slide rail 211 of the upper support 21 is designed as a straight section 2111 and a curved section 2112 that are interconnected. The shape of the slide rail allows for switching between the initial state and the tilted state of the toilet body 1: when the upper ends of the second cross arm 2312 and the fourth cross arm 2322 slide on the straight section 2111, the upper ends of the first cross arm 2311 and the second cross arm 2312 remain flush, and the upper ends of the third cross arm 2321 and the fourth cross arm 2322 remain flush. Therefore, the toilet... The main body 1 remains in its initial state. When the upper ends of the second cross arm 2312 and the fourth cross arm 2322 slide to the curved section 2112, the posture of the upper support 21 with the first slide rail 211 needs to change (thus causing the toilet main body 1 to switch to an inclined state) to offset the height difference between the curved section 2112 and the straight section 2111, so that the upper ends of the second cross arm 2312 and the fourth cross arm 2322 can still remain flush with the upper ends of the first cross arm 2311 and the third cross arm 2321. When the curved section 2112 bends downward, the part of the upper support 21 where the curved section 2112 is located needs to be raised to offset the height difference; when the curved section 2112 bends upward, the part of the upper support 21 where the curved section 2112 is located needs to be lowered to offset the height difference.

[0045] Therefore, in this design, the first slide rail 211 of the upper support 21 is designed as a straight section 2111 and a curved section 2112 that are connected to each other. The shape of the slide rail can be used to switch between the initial state and the tilted state of the toilet body.

[0046] Furthermore, this structural design allows the left and right crossarm assemblies to be driven synchronously by a single drive unit 24, eliminating the need to configure two separate drive units 24 for each crossarm assembly. This reduces the number of drive units 24, lowers the installation space requirements of the lifting system 2, avoids the collaborative control logic between the two drive units 24, simplifies the motor control program, reduces control complexity and failure risk, and further optimizes the overall structural compactness.

[0047] Of course, the first cross arm assembly 231 and the second cross arm assembly 232 can also be arranged side by side, and the two sets of cross arm assemblies can be independently driven to rise and fall by the drive device 24, thereby realizing the switching between the initial state and the tilted state of the toilet body 1. The first cross arm assembly 231 and the second cross arm assembly 232 arranged side by side can also be independently driven to rise and fall by the drive device 24.

[0048] In some exemplary embodiments, the upper end of the second cross arm 2312 is the rear end of the second cross arm 2312, the upper end of the fourth cross arm 2322 is the rear end of the fourth cross arm 2322, and the curved section 2112 is located at the rear of the first slide rail portion 211 and bends downward.

[0049] Alternatively, the upper end of the second cross sub-arm 2312 is the front end of the second cross sub-arm 2312, the upper end of the fourth cross sub-arm 2322 is the front end of the fourth cross sub-arm 2322, and the curved section 2112 is located in front of the first slide rail section 211 and curves upward.

[0050] By differentiating the upper positions (rear or front) of the second cross arm 2312 and the fourth cross arm 2322, and correspondingly matching the bending direction of the curved section 2112 of the first slide rail 211 (bending downward at the rear or upward at the front), the toilet body 1 can be tilted. Specifically, when the upper ends of the second cross arm 2312 and the fourth cross arm 2322 are the rear ends, and the curved section 2112 is located at the rear of the first slide rail 211 and bends downward, the rear ends of the second cross arm 2312 and the fourth cross arm 2322 slide along the curved section 2112, which will cause the rear of the toilet body 1 to rise more relative to the front, ultimately forming a tilted state where the rear is higher than the front. When the upper ends of the second cross arm 2312 and the fourth cross arm 2322 are the front ends, and the curved section 2112 is located in front of the first slide rail 211 and bends upward, the front ends of the second cross arm 2312 and the fourth cross arm 2322 slide along the curved section 2112, which will cause the front of the toilet body 1 to sink relative to the rear, thus achieving a tilted state where the rear is higher than the front. Both structural designs can rely on a single drive device 24 to synchronously drive the first cross arm assembly 231 and the second cross arm assembly 232, providing flexible and diverse structural solutions for achieving the tilted state of the toilet body 1 without increasing the complexity of drive and control, adapting to different assembly spaces and usage requirements.

[0051] In some exemplary embodiments, the driving device 24 includes a driving member 241 and a connecting rod 242; the driving member 241 is directly or indirectly connected to the connecting rod 242 and is configured to drive the connecting rod 242 to move. The two ends of the connecting rod 242 are respectively connected to a first cross arm 2311 and a third cross arm 2321, or the two ends of the connecting rod 242 are respectively connected to a second cross arm 2312 and a fourth cross arm 2322. The driving member 241 can be, but is not limited to, a motor, and the motor can be, but is not limited to, a linear motor.

[0052] Thus, the first crossarm assembly 231 and the second crossarm assembly 232 share the same drive unit 24.

[0053] In other embodiments, the drive device 24 further includes a transmission member, and the drive member 241 is connected to the connecting rod 242 via the transmission member. Exemplarily, the transmission member is a push rod, which is rotatably connected to the connecting rod 242; or, the transmission member includes a lead screw and a nut, the lead screw being connected to the drive member 241, the nut being threadedly engaged with the lead screw, and the nut being rotatably connected to the connecting rod 242.

[0054] In some exemplary embodiments, such as Figure 23 As shown, the driving component 241 includes a motor push rod 2411, which is rotatably connected to the connecting rod 242. The motor push rod 2411 can extend and retract. The driving component 241 also includes a sound-insulating shell 2412, sound-absorbing foam 2413, a motor sound-insulating cover 2414, and a motor body 2415. The sound-absorbing foam 2413 is fitted onto the motor body 2415, the sound-insulating shell 2412 is fitted onto the sound-absorbing foam 2413, and the motor sound-insulating cover 2414 is fastened to the end of the motor body 2415 away from the connecting rod 242 and connected to the sound-insulating shell 2412. The sound-insulating shell 2412 reflects sound waves and provides mechanical strength. The sound-insulating shell 2412 can be made of aluminum alloy and has pre-drilled openings to prevent the motor from overheating. The sound-absorbing foam 2413 can suppress resonance, absorb vibration, and reduce sound wave reflection; the motor sound-insulating cover 2414 can reduce noise transmission.

[0055] In some exemplary embodiments, such as Figure 14 As shown, the second cross arm 2312 is located on the side of the first cross arm 2311 near the second cross arm assembly 232, and the fourth cross arm 2322 is located on the side of the third cross arm 2321 near the first cross arm assembly 231. The two ends of the connecting rod 242 are connected to the second cross arm 2312 and the fourth cross arm 2322 respectively, and are offset from the lower ends of the second cross arm 2312 and the fourth cross arm 2322. The driving member 241 is capable of rotating relative to the lower support 22 about an axis extending along the width direction of the toilet body 1.

[0056] Since the drive component 241 needs to be directly or indirectly connected to the connecting rod 242 and drive its movement, and the end of the connecting rod 242 away from the drive component 241 will rise and fall with the second cross arm 2312 and the fourth cross arm 2322, the drive component 241 needs to rotate around the axis extending in the width direction of the toilet body 1. This rotational connection provides the drive component 241 with the necessary degree of freedom of movement, so that its movement trajectory does not conflict with the movement trajectory of the connecting rod 242. It can smoothly transmit driving force through its own rotation to push the connecting rod 242 to move, thereby ensuring that the connecting rod 242 drives the two cross arm assemblies to move in coordination, and drives the upper bracket 21 to move relative to the lower bracket 22.

[0057] Both the second cross arm 2312 and the fourth cross arm 2322 are provided with a first connecting protrusion 233 and a second connecting protrusion 234 spaced apart, and a limiting groove 235 is formed between the first connecting protrusion 233 and the second connecting protrusion 234. The two ends of the connecting rod 242 are respectively limited within the corresponding limiting grooves 235 and are fixedly connected to the second cross arm 2312 and the fourth cross arm 2322 respectively.

[0058] In this way, the two ends of the connecting rod 242 are correspondingly limited and fixedly connected within the limiting groove 235, which not only achieves precise positioning and assembly of the connecting rod 242 with the two cross arms, but also forms a bidirectional limiting on the end of the connecting rod 242 through the groove structure, which helps to prevent the connection part from shifting or loosening, and ensures that the driving force can be stably and synchronously transmitted to the first cross arm assembly 231 and the second cross arm assembly 232, which helps to ensure the consistency of the coordinated linkage of the two cross arm assemblies.

[0059] In some exemplary embodiments, the two ends of the connecting rod 242 are respectively provided with a third connecting protrusion 2421 and a fourth connecting protrusion 2422. One end of the connecting rod 242 is connected to the second cross arm 2312 through a first pivot pin 243 and a first fastener 244. The first pivot pin 243 passes through the second cross arm 2312 and the third connecting protrusion 2421 along the thickness direction of the second cross arm 2312. The first fastener 244 passes through the first connecting protrusion 233 of the second cross arm 2312 and one end of the connecting rod 242 along the length direction of the second cross arm 2312.

[0060] The other end of the connecting rod 242 is connected to the fourth cross arm 2322 via the second pivot pin 245 and the second fastener 246. The second pivot pin 245 passes through the fourth cross arm 2322 and the fourth connecting protrusion 2422 along the thickness direction of the fourth cross arm 2322. The second fastener 246 passes through the first connecting protrusion 233 of the fourth cross arm 2322 and the other end of the connecting rod 242 along the length direction of the fourth cross arm 2322.

[0061] The fourth connecting protrusion 2422 includes two connecting plates 2423 spaced apart. The driving member 241 is provided with a connecting lug 2416, which is sandwiched between the two connecting plates 2423 and is rotatably connected to the fourth connecting protrusion 2422 through the second pivot pin 245.

[0062] The connecting lug 2416 can be located at one end of the motor push rod 2411 near the connecting plate 2423. In this way, by engaging the third connecting lug 2421 and the fourth connecting lug 2422 at both ends of the connecting rod 242 with the limiting grooves 235 of the second cross arm 2312 and the fourth cross arm 2322, combined with the first pivot pin 243 and the second pivot pin 245 arranged along the thickness direction of the cross arm, and the first fastener 244 and the second fastener 246 arranged along the length direction of the cross arm, a bidirectional positioning and double fixing structure is formed. This achieves a stable connection between the connecting rod 242 and the two sets of cross arms, effectively preventing loosening at the connection points. The drive component 241's connecting lug 2416 is clamped between the two connecting plates 2423 of the fourth connecting protrusion 2422 and rotatably connected by the second pivot pin 245, making the connection between the drive component 241 and the connecting rod 242 compact and smooth. This ensures that the driving force can be stably and synchronously transmitted to the second cross arm 2312 and the fourth cross arm 2322, which is beneficial to ensuring the consistency of the coordinated linkage of the cross arm components. Moreover, the overall connection structure is ingeniously designed and easy to assemble, taking into account both structural strength and movement flexibility.

[0063] In some exemplary embodiments, such as Figure 14 and Figure 16 As shown, the lower support 22 is provided with a base 221, and a drive member 241 is rotatably mounted on the base 221, and the drive member 241 is biased toward the second cross arm assembly 232. The base 221 may be located at the rear end of the lower support 22.

[0064] By mounting the drive component 241 on the lower bracket 22, the positional relationship between the drive component 241 and the lower bracket 22 can be kept stable, avoiding damage to the drive component 241 due to pulling or interference between the drive component 241 and the lifting assembly 23 when the position of the lower bracket 22 shifts. The drive component 241 is offset towards the second cross arm assembly 232 based on spatial layout optimization considerations, fully freeing up space on one side of the first cross arm assembly 231 to better accommodate the usage requirements of the sewage discharge device 12. As mentioned earlier, since the sewage discharge pipe 122 needs to rotate towards the first cross arm assembly 231 to discharge sewage, the required movement space on that side is larger, and therefore the required installation space for the sewage discharge device 12 on that side is also larger. Therefore, the design of offsetting the drive component 241 to the other side avoids spatial interference between the drive device 12 and the sewage discharge device 12, and makes the overall structural layout more reasonable and compact. While meeting functional requirements, it improves space utilization and balances assembly feasibility and operational reliability.

[0065] In some exemplary embodiments, the connecting rod 242 bends away from the drive member 241, which can provide a larger space between the connecting rod 242 and the drive member 241 to accommodate the bottom of the toilet bowl 111, the sewage discharge device 12 and other structures.

[0066] In some exemplary embodiments, the lower support 22 is provided with two parallel and spaced second slide rail portions 222, and the lower ends of the first cross arm 2311 and the third cross arm 2321 respectively slide in engagement with the corresponding second slide rail portions 222. This guides the sliding of the lower ends of the first cross arm 2311 and the third cross arm 2321, which helps to improve the smoothness of the sliding.

[0067] The first slide rail portion 211 is configured as a slide groove with one open end, and the open ends of the two first slide rail portions 211 are arranged facing each other. The second slide rail portion 222 is configured as a slide groove with one open end, and the open ends of the two second slide rail portions 222 are arranged facing each other. The second slide rail portion 222 is a straight slide rail portion, such as... Figure 17 and Figure 18 As shown.

[0068] Thus, the two first slide rails 211 of the upper bracket 21 and the two second slide rails 222 of the lower bracket 22 are parallel and spaced apart with their opening ends facing each other. This structural design provides precise guidance for the sliding of the second cross arm 2312, the fourth cross arm 2322, the first cross arm 2311, and the third cross arm 2321, ensuring the smoothness of movement and the consistency of trajectory when the first cross arm assembly 231 and the second cross arm assembly 232 are linked. It also facilitates the assembly and disassembly of each cross arm and its corresponding slide rail. When the drive member 241 drives the connecting rod 242 to move, it will simultaneously drive the upper ends of the second cross arm 2312 and the fourth cross arm 2322 to slide along the corresponding first slide rail 211, while the lower ends of the first cross arm 2311 and the third cross arm 2321 slide along the corresponding second slide rail 222, so that the two sets of cross arm assemblies always maintain a stable trajectory during the linkage process.

[0069] In some embodiments, rollers 236 are provided at the lower end of the first cross arm 2311, the upper end of the second cross arm 2312, the lower end of the third cross arm 2321, and the upper end of the fourth cross arm 2322, such as... Figure 14 as well as Figure 16 As shown. The roller 236 rolls within the grooves of the first slide rail 211 and the second slide rail 222, which reduces the friction between each cross arm and the upper support 21 and the lower support 22, thereby improving its sliding smoothness and reducing the power requirement of the drive component. The roller 236 can be, but is not limited to, a plastic-coated bearing.

[0070] In some exemplary embodiments, such as Figure 15 As shown, the first cross arm 2311 includes a first arm segment 23111, a second arm segment 23112, and a third arm segment 23113. The first arm segment 23111 and the third arm segment 23113 are spaced apart along the length of the first cross arm 2311. The second arm segment 23112 is located on the side of the first arm segment 23111 and the third arm segment 23113 away from the second cross arm 2312, and both ends of the second arm segment 23112 are connected to the first arm segment 23111 and the third arm segment 23113, respectively, so that the first arm segment 23111, the second arm segment 23112, and the third arm segment 23113 enclose a first clearance groove 23114. The second cross arm 2312 passes through the first clearance groove 23114 and is rotatable relative to the first clearance groove 23114.

[0071] The third cross arm 2321 includes a fourth arm segment 23211, a fifth arm segment 23212, and a sixth arm segment 23213. The fourth arm segment 23211 and the sixth arm segment 23213 are spaced apart along the length of the third cross arm 2321. The fifth arm segment 23212 is located on the side of the fourth arm segment 23211 and the sixth arm segment 23213 away from the fourth cross arm 2322, and both ends of the fifth arm segment 23212 are connected to the fourth arm segment 23211 and the sixth arm segment 23213, respectively, so that the fourth arm segment 23211, the fifth arm segment 23212, and the sixth arm segment 23213 enclose the second clearance groove 23214. The fourth cross arm 2322 passes through the second clearance groove 23214 and is rotatable relative to the second clearance groove 23214.

[0072] In this way, by designing the first cross arm 2311 as a structure in which the first arm segment 23111, the second arm segment 23112, and the third arm segment 23113 enclose the first clearance groove 23114, and designing the third cross arm 2321 as a structure in which the fourth arm segment 23211, the fifth arm segment 23212, and the sixth arm segment 23213 enclose the second clearance groove 23214, the second cross arm 2312 passes through the first clearance groove 23114 and the fourth cross arm 2322 passes through the second clearance groove 23214, and both can rotate relative to their corresponding clearance grooves. This design is also based on optimizing the spatial layout, cleverly avoiding the installation and movement space of the second cross arm 2312 and the fourth cross arm 2322. The space (equivalent to hiding the second cross arm 2312 within the movement range of the first cross arm 2311, and hiding the fourth cross arm 2322 within the movement range of the third cross arm 2321, while the second arm segment 23112 and the fourth arm segment 23211 protrude outwards, without occupying the space between the two cross arm components, thus facilitating the provision of installation space for the toilet body 1) effectively reduces the overall volume occupied by each cross arm component, avoids mutual interference between internal structures, and retains the structural integrity and support strength of each cross arm through the multi-arm segment connection structure. The load-bearing capacity and transmission stability of the two cross arm components are not reduced due to space optimization, ultimately achieving a balance between spatial compactness and structural strength.

[0073] In some exemplary embodiments, such as Figure 14As shown, the upper support 21 includes a first frame 212, a second frame 213, a third frame 214, and a fourth frame 215 connected end to end. The first frame 212 and the third frame 214 are arranged parallel to each other along the width direction of the toilet body 1, and the second frame 213 and the fourth frame 215 are arranged parallel to each other along the length direction of the toilet body 1. The lower support 22 includes a fifth frame 223, a sixth frame 224, a seventh frame 225, and an eighth frame 226 connected end to end. The fifth frame 223 and the seventh frame 225 are arranged parallel to each other along the width direction of the toilet body 1, and the sixth frame 224 and the eighth frame 226 are arranged parallel to each other along the length direction of the toilet body 1.

[0074] Compared to the design where both the upper support 21 and the lower support 22 consist of only two parallel and spaced support rods, this design features a closed-loop design where the upper support 21 and the lower support 22 are connected end to end. This enhances the load-bearing capacity of the upper support 21 and the lower support 22, enabling more reliable transmission of driving force and support of the toilet body 1. This helps ensure the smooth and precise execution of lifting and tilting movements.

[0075] The first frame 212 and the third frame 214 may be provided with the aforementioned first slide rail portion 211, and the fifth frame 223 and the seventh frame 225 may be provided with the aforementioned second slide rail portion 222. The first frame 212 and the third frame 214 of the upper support 21, and the fifth frame 223 and the seventh frame 225 of the lower support 22 are arranged parallel to each other along the width direction of the toilet body 1, and are correspondingly provided with a first slide rail portion 211 and a second slide rail portion 222 with a U-shaped cross-section and inward-facing openings, as shown below. Figure 17 and Figure 18 As shown, the closed-loop structure provides a stable installation base for the first slide rail 211 and the second slide rail 222. The parallel and symmetrical layout of the two slide rails makes the sliding force of the cross arm more balanced. Combined with the limiting and guiding function of the U-shaped slide rail, it effectively improves the structural rigidity and motion stability of the entire lifting system, which helps to avoid problems such as deviation and shaking during the movement.

[0076] In some exemplary embodiments, such as Figure 1 , Figure 14 and Figure 19 The upper support 21 is also provided with multiple support seats 216 and multiple first support columns 217, which are spaced apart circumferentially along the upper support 21. The toilet body 1 is provided with multiple support protrusions 16, which are arranged one-to-one with the multiple support seats 216 and are fixedly connected by horizontally installed third fasteners 17. The multiple first support columns 217 are fixedly connected to the toilet body 1 by vertically installed fourth fasteners (not shown). The lower support 22 is also provided with multiple second support columns 227, and the upper support 21 can be supported by the multiple second support columns 227.

[0077] In this way, by setting multiple support seats 216 and first support columns 217 at circumferential intervals on the upper bracket 21, the support protrusions 16 of the toilet body 1 correspond one-to-one with the support seats 216 and are fixed by the third fasteners 17 in the horizontal direction. The first support column 217 is connected to the toilet body 1 by the fourth fastener in the vertical direction, forming a multi-point fixing structure that cooperates in the horizontal and vertical directions. This greatly improves the stability of the connection between the upper bracket 21 and the toilet body 1, which helps to prevent relative displacement between the two and ensures reliable force transmission. At the same time, the multiple second support columns 227 set on the lower bracket 22 can provide stable support for the upper bracket 21 to fall back to its initial state. This can prevent the lifting component 23 from bearing the load of the toilet body 1 and other structures alone for a long time when not in use, thereby enhancing the load-bearing capacity of the entire mechanism. The multi-point force-distribution design also extends the service life of the structure.

[0078] In some exemplary embodiments, such as Figure 14 As shown, at least one of the support base 216, the first support column 217, and the second support column 227 is provided with a vibration damping component to reduce vibration. This is beneficial for reducing the contact noise between the upper support 21 and the lower support 22, as well as the contact noise between the upper support 21 and the toilet body 1.

[0079] In some embodiments, the support base 216 is provided with a positioning groove 2161, and the support protrusion 16 is confined within the positioning groove 2161. A vibration damping element is provided within the positioning groove 2161. The first frame 212, second frame 213, and third frame 214 are each provided with a support base 216, and the connection points between the first frame 212 and the fourth frame 215, and between the third frame 214 and the fourth frame 215, are provided with first support columns 217. Second support columns 227 are provided at both ends of the fifth frame 223 and both ends of the sixth frame 224.

[0080] Among them, the damping components on the support base 216 and the first support column 217 can be, but are not limited to, buffer damping foam 25, and the damping components on the second support column 227 can be, but are not limited to, silicone pad 26.

[0081] In this way, the positioning groove 2161 of the support base 216 limits the support protrusion 16 of the toilet body 1, and the vibration damping component design within the positioning groove 2161 achieves precise positioning and assembly between the toilet body 1 and the upper bracket 21, preventing misalignment of the connection points. It also effectively buffers the impact vibrations generated during the lifting and tilting of the toilet body 1, reducing operating noise. Simultaneously, the reasonable distribution of the support base 216 and the first support column 217 along the circumference of the upper bracket 21, and the placement of the second support column 227 at the corresponding end of the lower bracket 22, ensures that vibration damping and support evenly cover key stress points. While ensuring stable contact between the upper bracket 21 and the toilet body 1, and between the upper bracket 21 and the lower bracket 22, it further improves the smoothness and quietness of the mechanism's operation, enhancing the user experience. Furthermore, the selection of vibration damping component types caters to the needs of different support scenarios, balancing vibration damping effect with structural practicality.

[0082] In some exemplary embodiments, the toilet body 1 also includes a millimeter-wave radar module 141, which is mounted on the toilet seat 14 and configured to detect human signals within a set range. Figure 25 and Figure 26 As shown.

[0083] The toilet also includes a control system. The millimeter-wave radar module 141 is electrically connected to the control system, which facilitates the automatic control of the toilet based on the detection results of the millimeter-wave radar module 141.

[0084] In some exemplary embodiments, such as Figure 7 As shown, the toilet also includes a grab handle 5, which is connected to the toilet body 1. The grab handle 5 can be detachably fixed to the toilet base 11. To address the issue that some users (weak patients, the elderly) may experience dizziness and feel unsafe during the lifting and lowering process, the detachable grab handle 5 is provided to create a safe environment (suitable for the elderly, patients, and other people with mobility difficulties).

[0085] In summary, the toilet provided in this application has the following advantages: It adopts a modular, split-structure design, with its lifting system 2 configured as an independent, detachable unit, allowing for quick assembly and disassembly with the toilet body 1 and toilet base 4. This significantly simplifies the production and assembly process, and subsequent maintenance and component replacement do not require disassembling the entire unit, making operation convenient and efficient. Furthermore, the lifting system can be replaced individually as needed, reducing maintenance costs and increasing usability. It features a silent design, effectively reducing noise pollution, protecting users' hearing, aligning with green environmental protection principles, and significantly improving user comfort. The concealed design enhances space neatness and improves space utilization, while also enabling dynamic functional display (the lifting action is only shown during use). Simultaneously, optimized protection significantly reduces the risk of bumps during the toilet's lifting process. The closed-loop double-rail design greatly improves the rigidity and deformation resistance of the support, while achieving a four-way equal load layout (uniform force distribution on the support from top to bottom and left to right), effectively enhancing the operational stability of the lifting system. Equipped with detachable power armrests 5, it has anti-slip, anti-fall, and balance assistance functions, which can not only enhance the safety of use, but also create a safe and relaxing use environment and improve the user's psychological comfort.
