Description

Technical Field

[0001] The present invention relates to a squatting toilet aid and its working method, belonging to the technical field of living aids. Background Art

[0002] In existing buildings, squat toilets are still in use in the bathrooms of quite a number of places. For the elderly and those with difficulty in squatting, using a squat toilet consumes a lot of energy and is very inconvenient. With the increasing number of the elderly population in China year by year, there is a need to provide an auxiliary device for use with squat toilets.

[0003] The Chinese utility model patent with the publication number CN201675851U and the authorization announcement date of December 22, 2010 discloses a new type of externally foldable squat toilet chair, which can directly adopt or refer to the structure of an ordinary folding chair. An armrest device is provided on the upper half of the support frame, and a squat toilet board is installed in the middle part. The squat toilet board is designed in a "U" - shaped structure or a "C" - shaped structure. Although this squat toilet chair can be folded and assist in squatting, its height after unfolding is fixed and cannot adapt to users of all heights, still having the problem of inconvenient use, with an unclear auxiliary effect and low efficiency. Summary of the Invention

[0004] The purpose of the present invention is to address the above - mentioned deficiencies of the prior art and provide a squatting toilet aid and its working method, which can adapt to users of different heights, is convenient and fast to operate, simple to fold, and does not occupy space.

[0005] The technical solution of the present invention is as follows:

[0006] The squatting toilet aid is characterized by including:

[0007] A cushion assembly for contacting the buttocks;

[0008] A lifting assembly, including two front legs, two rear legs, and a lifting device, which synchronously adjusts the heights of the front legs and the rear legs through the lifting device;

[0009] A folding assembly, which rotates and folds the front legs and the rear legs through the folding assembly.

[0010] Adopting the above - mentioned scheme, through the folding assembly, the whole aid can be unfolded or folded and stored; through the lifting assembly, the four legs can be synchronously lifted or lowered to adapt to the height of the user.

[0011] Further, both of the two front legs adopt pneumatic lifting rods, and the two rear legs are follower lifting rods.

[0012] With the above - mentioned solution, the four legs are divided into two groups, front and back. Different lifting devices are used for the two groups of legs. The power of the two pneumatic lifting rods is sufficient to assist the user in adaptively adjusting the height of the assistor. For the other two, follow - up lifting components can be used. The structure is simpler, the operation is more convenient, and the cost is saved.

[0013] Furthermore, the follow - up lifting rod includes a support sleeve, a T - shaped support rod, and a spring. The T - shaped end of the T - shaped support rod presses the spring and is installed in the cavity of the support sleeve. The T - shaped end of the T - shaped support rod can prevent the T - shaped support rod from sliding out of the support sleeve.

[0014] With the above - mentioned solution, under the action of the spring and external force, the T - shaped support rod can move up and down in the support sleeve to change or maintain its own height.

[0015] Furthermore, the lifting device includes a front adjustment component and a rear adjustment component; the front adjustment component includes an adjustment handle and a front adjustment shaft, and the rear adjustment component includes a rear adjustment shaft and a flexible connection component; the front adjustment shaft passes through the hinge connection components at the two front legs and is rotatably connected to them, and the rear adjustment shaft passes through the hinge connection components at the two rear legs and is rotatably connected to them; the adjustment handle is fixedly connected to the end of the front adjustment shaft, and the adjustment handle is connected to the rear adjustment shaft through a flexible connection component; by adjusting the handle to control the air - valve control components of the two pneumatic lifting rods, the front and rear legs are driven to lift and lower synchronously.

[0016] With the above - mentioned solution, by adjusting the handle to control the lifting of the pneumatic lifting rod, at the same time, the adjustment handle can tighten the flexible connection component (such as a steel wire rope), and the straight flexible connection component is used to integrate the front and rear legs so that they lift and lower synchronously.

[0017] Furthermore, two adjustment plates are fixedly connected to the front adjustment shaft, and the positions of the two adjustment plates correspond to the air - valve control components of the two pneumatic lifting rods respectively.

[0018] With the above - mentioned solution, when the adjustment handle controls the air - valve control components of the pneumatic lifting rod to act, the two adjustment plates act accordingly and immediately trigger the air - valve control components of the corresponding two pneumatic lifting rods to adjust the height of the pneumatic lifting rods.

[0019] Furthermore, pull rods are provided at both the rear adjustment shaft and the adjustment handle, and the two ends of the flexible connection component are respectively connected to the two pull rods; a guide component for the flexible connection component is also provided. One end of the guide component is fixedly connected to the end of the front adjustment shaft, and the other end is provided with a U - shaped structure for the flexible connection component to pass through.

[0020] With the above solution, the setting of the pull rod can facilitate the propping up of the flexible connecting piece, so that the flexible connecting piece is not interfered, and it is convenient to synchronously trigger the lifting of the front and rear legs. On the one hand, the guiding piece can guide the flexible connecting piece to prevent deviation. On the other hand, it can serve as the fulcrum of the flexible connecting piece (which can be higher than the connection points at both ends of the flexible connecting piece), facilitating the straightening and tensioning of the flexible connecting piece, and contributing to the synchronism of the actions of the front and rear legs.

[0021] Further, the folding assembly includes:

[0022] A hinge connecting piece for connecting the front and rear legs and the seat cushion assembly to facilitate the rotational folding of the four legs;

[0023] Side connecting rods, with both ends of the side connecting rods hinged to the front and rear legs on the same side respectively to facilitate the synchronous rotational folding of the front and rear legs on the same side.

[0024] Further, a replaceable shielding assembly is provided at the bottom of the seat cushion assembly, and the replaceable shielding assembly unfolds or retracts along the bottom of the seat cushion assembly. Before use, the shielding assembly can be retracted along the circular track formed at the bottom of the seat cushion assembly; during use, the shielding assembly can be unfolded along the seat cushion assembly to prevent the splashing of excrement; after use, the shielding assembly can be detached and replaced, and the shielding assembly can adopt disposable paper or film.

[0025] The working method of the above squatting toilet aid is characterized in that

[0026] 1) Unfold the seat cushion assembly, the front legs, and the rear legs through the folding assembly;

[0027] 2) The user sits on the seat cushion assembly, holds the adjustment handle, and lifts it upwards. At this time:

[0028] a. The adjustment handle flips forward, drives the front adjustment shaft to rotate, drives the adjustment plate to flip, and the adjustment plate presses down the air valve control part of the corresponding pneumatic lifting rod, and the user adaptively adjusts the height of the two front legs by their own weight;

[0029] b. The adjustment handle flips forward, and at the same time triggers the flexible connecting piece to tighten and pull the rear adjustment shaft, so that the front and rear adjustment shafts act synchronously; during the lifting and lowering process of the pneumatic lifting rod, the height of the front adjustment shaft changes accordingly, and the height of the rear adjustment shaft also changes accordingly. The rear adjustment shaft drives the follower lifting rod to lift and lower synchronously with the pneumatic lifting rod;

[0030] 3) When the seat cushion assembly reaches the appropriate height, the user releases the adjustment handle, drives the adjustment plate away from the air valve control part of the corresponding pneumatic lifting rod, and the length of the pneumatic lifting rod is stable; under the action of the user's own weight, overcoming the spring force, the length of the follower lifting rod is stable and is at the same height as the pneumatic lifting rod.

[0031] The structure of the present invention is simple and reasonable, and it is easy to manufacture. Compared with the prior art, it realizes "one-key" lifting (simply by operating the adjusting handle), and has the characteristics of convenient use, simple operation, safety and hygiene, and less storage space occupation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0043] Embodiment 1

[0044] The squatting toilet seat assistant, as Figure 1-2 shown, includes a seat cushion assembly, a lifting assembly, and a folding assembly.

[0045] Wherein:

[0046] The seat cushion assembly is composed of a seat cushion plate 1 and a base 2 that are folded and rotatable to open;

[0047] The lifting assembly includes two front legs 3, two rear legs 4, and a lifting device, and the height of the front legs and the rear legs is synchronously adjusted by the lifting device;

[0048] The folding assembly rotates and folds the front legs and the rear legs through the folding assembly; the folding assembly includes:

[0049] The hinge connecting piece is composed of an upper U-shaped piece 5 fixed to the base and a lower U-shaped piece 6 fixedly connected to the upper part of the leg. The upper U-shaped piece and the lower U-shaped piece are hinged by a pin, and are used to connect the front and rear legs to the seat cushion assembly for the rotational folding of the four legs;

[0050] The side link 7, and both ends of the side link are respectively hinged to the front and rear legs on the same side, so that the front and rear legs on the same side are synchronously rotated and folded; connecting cross bars 8 are provided between the front legs and between the rear legs.

[0051] Embodiment 2

[0052] On the basis of Embodiment 1, as Figure 1-2 shown, both of the two front legs 3 adopt pneumatic lifting rods (the lifting principle is the same as that of the pneumatic rod on an office chair), and the two rear legs 4 are follower lifting rods. As Figure 3 shown, the follower lifting rod includes a support sleeve 9, a T-shaped support rod 10, and a spring 11. The T-shaped end of the T-shaped support rod presses the spring and is installed in the cavity of the support sleeve. The T-shaped end of the T-shaped support rod can prevent the T-shaped support rod from sliding out of the support sleeve. Under the combined action of the spring, the user's own weight, and the pneumatic lifting rod, the T-shaped support rod can move up and down in the support sleeve so as to change or maintain its own height with the change of the height of the pneumatic lifting rod.

[0053] The power of the two pneumatic lifting rods is sufficient to assist the user in adaptively adjusting the height of the assistor, and the other two can adopt follower lifting members. If pneumatic lifting rods are adopted for both the front and rear legs, the power of the four pneumatic lifting rods will be too large, and the user cannot smoothly adjust the height by using their own weight.

[0054] Embodiment 3

[0055] On the basis of Embodiment 2, the front adjustment assembly of the lifting device includes an adjustment handle 12 and a front adjustment shaft 13, and the rear adjustment assembly of the lifting device includes a rear adjustment shaft 14 and a flexible connecting member (in this embodiment, a steel wire rope 15 is adopted); the front adjustment shaft 13 passes through the lower U-shaped piece 6 at the two front legs and is rotatably connected thereto, and the rear adjustment shaft 14 passes through the lower U-shaped piece 6 at the two rear legs and is rotatably connected thereto.

[0056] There are two adjusting plates 16 fixedly connected to the front adjusting shaft. The two adjusting plates correspond to the air valve control parts 17 of two pneumatic lifting rods respectively. The adjusting handle is fixedly connected to the end of the front adjusting shaft. Tie rods 18 are provided at the rear adjusting shaft and the adjusting handle. Both ends of the steel wire rope 15 are connected to the two tie rods respectively.

[0057] When the user sits on the cushion plate 1 and raises the adjusting handle, the two adjusting plates will act accordingly, and immediately press down to trigger the air valve control parts 17 of the corresponding two pneumatic lifting rods (as Figure 4-5 shown); when the adjusting handle moves, the steel wire rope will immediately respond and become taut. Both ends of the steel wire rope firmly tighten the front and rear adjusting shafts to form an integral body, so that the rear legs can be lifted and lowered synchronously.

[0058] When the user sits on the auxiliary device, considering the user's habits, generally, the user sits at the front end of the cushion plate 1 first. That is, when starting to use, the human pressure on the front legs is often greater than that on the rear legs. In addition, the front legs use pneumatic lifting rods as the lifting power source, and the rear legs use springs to follow and lift. As the user slowly moves the buttocks to the middle of the cushion plate 1, the front and rear legs can complete the linkage lifting process. Therefore, there may be a slight height difference between the front and rear legs during the lifting process. Using a steel wire rope, on the one hand, it can meet the strength requirements, connect the front and rear adjusting shafts, and make the front and rear legs lift synchronously; on the other hand, if there is a slight height difference between the front and rear legs, the straight-line distance between the front and rear adjusting shafts will have some dynamic changes. A flexible connection is suitable between the front and rear adjusting shafts, while a rigid connection is easily damaged and is not conducive to the stable operation of the auxiliary device. The unique soft performance and strength of the steel wire rope can well adapt to the above dynamic changes, and can always pull and tow the rear adjusting shaft during the lifting process, making the front and rear adjusting shafts form an integral body; on the third hand, after the adjusting handle is reset, the steel wire rope can immediately stop pulling and towing the rear adjusting shaft, occupying a small space and not interfering with other components.

[0059] On this basis, the setting of the tie rod 18 can facilitate the erection of the flexible connecting piece, so that the flexible connecting piece is not interfered and is convenient for synchronously triggering the lifting of the front and rear legs; as Figure 7 shown, one end of the guiding piece 19 is fixedly connected to the end of the front adjusting shaft, and the other end is provided with a U-shaped structure for the flexible connecting piece to pass through. It can be used as a fulcrum of the steel wire rope during the lifting process, which is convenient for further straightening and tightening the steel wire rope and helps to pull and tow the rear legs.
