Description

Technical Field

[0001] The invention belongs to the technical field of sanitary ware, and in particular relates to a liftable toilet seat assembly and a barrier-free power-assisted toilet. Background Art

[0002] Accessible design is an important manifestation of social civilization. Patients in the postoperative recovery period, pregnant women, the elderly and other groups are facing the problem of using the toilet. They generally have difficulties such as being unable to squat, squatting incorrectly, and standing up, and they are in urgent need of corresponding barrier-free facilities.

[0003] In response to this practical difficulty, a common practice is to install various forms of handrails around the toilet to facilitate users to hold on, but the installation of handrails still requires users to actively exert force, so the auxiliary effect is very limited. In addition, some toilets with squatting and standing assistance functions have also been developed and designed in the prior art, but due to incomplete considerations in design and function, they have not been actually promoted and applied for a long time. Summary of the invention

[0004] During the implementation of the present invention, we found that the existing liftable power-assisted toilets still have the following defects. First, the toilet seat of the existing liftable power-assisted toilets generally cannot be flipped up, which makes it impossible to use it as a universal toilet for normal people, and the utilization efficiency is low; second, the cleaning and disinfection of the existing liftable power-assisted toilets are very inconvenient; third, the existing liftable power-assisted toilets are mostly integrated designs, and their installation requires the original toilet to be replaced as a whole, which is cumbersome and costly; fourth, there are users with extreme weights in reality. If the structure design and motor selection are carried out according to users with extreme weights, the redundancy will be very serious, resulting in very high costs and cannot be promoted and applied. The current practice is generally to design according to normal weight and add a small amount of redundancy, but it is easy to cause motor damage and lifting structure damage when encountering overweight users.

[0005] The purpose of the present invention is to provide a liftable toilet seat assembly and a barrier-free power-assisted toilet to solve the above-mentioned problems.

[0006] The present invention is achieved through the following technical solutions: a liftable toilet seat assembly, comprising a toilet seat, a pair of clamping assemblies, a pair of arc-shaped racks, and a pair of drive boxes; the pair of drive boxes are fixedly arranged on both sides of the toilet, and each drive box is provided with a slide groove cooperating with the arc-shaped rack and a power device driving the arc-shaped rack to slide in the slide groove; the arc-shaped rack protrudes toward the rear of the toilet, and a set of clamping assemblies is provided on the top of each arc-shaped rack, and the two sets of clamping assemblies are respectively connected to the two sides of the toilet seat; the clamping assembly includes at least two stable states, at least one of which corresponds to the lowered state of the toilet seat, and at least one of which corresponds to the flipped-up state of the toilet seat.

[0007] The liftable toilet seat assembly provided by the present invention is lifted and lowered by an arc-shaped rack protruding toward the rear of the toilet. When the toilet seat is in a lower position, the toilet seat is substantially horizontal. When the toilet seat is in a raised state, the toilet seat tilts forward, thereby facilitating the user's squatting and standing up. In addition, the liftable toilet seat assembly is provided with a clamping assembly between the arc-shaped rack and the toilet seat. The toilet seat can be manually flipped when not raised, and can be used like an ordinary toilet, and is also convenient for cleaning and disinfection. After an ordinary toilet is installed with the liftable toilet seat assembly of the present invention, it can retain the versatility of the original ordinary toilet and also has squatting and standing assistance functions.

[0008] Furthermore, the clamping assembly includes a first clamping member and a second clamping member; the first clamping member includes a first fixing block and a pillar fixed at one end of the first fixing block; a waist-shaped hole is penetrated through the pillar, and the extension direction of the waist-shaped hole is consistent with the extension direction of the pillar; the second clamping member includes a second fixing block and a pair of ears fixed at one end of the second fixing block, and a pin is connected between the ears; the pin passes through the waist-shaped hole; a first countersunk hole for accommodating the ear is also provided on the end face of the first fixing block, and a second countersunk hole for accommodating the pillar is also provided on the end face of the second fixing block.

[0009] The connection method of the clamping assembly between the arc-shaped rack and the toilet seat can be selected from any of the following two methods. The first method is: the first clamping member is fixed to the top of the arc-shaped rack, and the second clamping member is fixed to the bottom of the toilet seat. The second method is: the first clamping member is fixed to the bottom of the toilet seat, and the second clamping member is fixed to the top of the arc-shaped rack.

[0010] The following uses the first connection method as an example to illustrate the two stable states and transformations of the snap-on assembly. The snap-on assembly can form two stable states. The first stable state corresponds to the state where the toilet seat is not turned up. At this time, the pillar extends into the second countersunk hole, and the lug extends into the first countersunk hole, forming a snap-on fixed state that cannot rotate around each other; the second stable state corresponds to the state where the toilet seat is turned up. Starting from the first stable state, the toilet seat is lifted up to move the pin to the top of the waist-shaped hole, and then the toilet seat is rotated about 90° with the pin as the rotation center, and then the toilet seat is lowered to make the pin away from the top of the waist-shaped hole to form the second stable state.

[0011] Further, the first clamping member is preferably detachably mounted on the top of the arc-shaped rack, and the second clamping member is preferably detachably mounted on the bottom of the toilet seat. The detachable mounting method can select a suitable mounting method in the prior art, such as threaded fitting connection and fixing.

[0012] Furthermore, the power device includes a motor and a transmission gear set; the motor is fixed in the drive box, and the driving force of the motor is transmitted to the arc-shaped rack through the transmission gear set, thereby driving the arc-shaped rack to slide along the slide groove, and finally driving the toilet seat to rise and fall. Among them, the motor preferably uses a motor with a power-off self-locking function, such as a brake-type self-locking motor, to prevent the toilet seat from falling suddenly when the power is off.

[0013] Furthermore, a torque limiter is provided in the transmission gear set or between the transmission gear set and the motor. The torque limiter is a trade-off setting that takes into account cost and practical availability. When used by users of extreme weight, the power output by the motor is insufficient to drive the toilet seat to rise stably. At this time, the torque limiter slips, thereby protecting the motor and the lifting structure. In addition, the torque limiter's own damping effect can prevent the toilet seat from falling rapidly when the force exceeds the limit, so it will not cause harm to users of extreme weight. In actual use, the applicable weight range should be marked in a conspicuous position.

[0014] Furthermore, the upper end of the driving box is open, and an upper cover is provided at the opening, and a through hole is provided on the upper cover for the arc-shaped rack to pass through.

[0015] Furthermore, the bottom of the driving box is fixed on the ground at both sides of the toilet, which has good stability.

[0016] Furthermore, the present invention also provides a barrier-free power-assisted toilet, which includes the above-mentioned liftable toilet seat assembly and a toilet. The liftable toilet seat assembly is installed in a suitable installation position so that the toilet seat corresponds to the opening of the toilet.

[0017] Beneficial effects: Compared with the prior art, the liftable toilet seat assembly provided by the present invention can not only retain the versatility of the original ordinary toilet, but also has the squatting and standing assisting functions. In addition, the liftable toilet seat assembly also has the advantages of being easy to clean and disinfect, no need to replace the entire toilet, controllable cost, and adaptable to users of most weights.
