Abstract
Description
Technical Field
[0001] This utility model relates to the field of toilet technology, and in particular to a splash-proof, internal flow type toilet structure. Background Technology
[0002] A bedpan is a basin-shaped device used for urination and defecation. It is mainly used for people who are unable to use the toilet independently, such as patients who are unable to move or bedridden, and the elderly. Bedpans are widely used in medical or home care scenarios, such as assisting postoperative patients, critically ill patients or paralyzed elderly people to defecate. Its design is usually an oval opening at one end (the larger end facing the head) and a narrower end (the smaller end facing the feet), which makes it easy to fit the human body posture.
[0003] The structure of traditional bedpans is relatively simple, and most of them use a fixed rigid outline, which makes it difficult to adapt to the body curves of different users. This results in a large gap between the bedpan and the body, and insufficient fit. During use, it is very easy for waste to leak out, which not only stains clothes and the environment, increases the workload of cleaning, but also causes great embarrassment and discomfort to users. This problem is more obvious for patients with limited mobility, the elderly and other groups, and seriously affects the quality of care and dignity of life. Summary of the Invention
[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a splash-proof internal flow toilet structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A splash-proof, internally flowing toilet structure includes a toilet body, a groove on one side of the toilet body, and a stool collection section at the bottom of the groove. A water inlet pipe is provided on one side of the toilet body, and an installation groove is provided on the outer periphery of the toilet body. A slow-flow channel device is provided in the installation groove. The water inlet end of the slow-flow channel device is connected to the water inlet pipe, and the water outlet end is set towards the inner wall of the groove. It is used to form a slow-flow area on the outer side of the inner wall of the groove, guide the water flow along the inner wall of the groove and cover the inner wall of the groove. The toilet bowl body is provided with an installation plate, the top of the installation plate is provided with an opening, a bladder is installed in the opening, a connecting pipe is provided on one side of the bladder, and one side of the connecting pipe is connected to the water inlet pipe. The water inlet pipe can selectively supply water to the slow-flow channel device, or fill the bladder with water through the connecting pipe. When water is filled into the bladder, the bladder can bulge upward along the opening and fit against the part of the human body that comes into contact with it.
[0006] Preferably, the slow-flow channel device includes a water outlet pipe disposed in the installation groove, the water inlet pipe is connected to the water outlet pipe, and a plurality of water outlets are provided on the inner wall of the groove, and the plurality of water outlets are connected to the water outlet pipe through pipes.
[0007] Preferably, a drain pipe is provided on one side of the bladder, and one end of the drain pipe is connected to a water outlet pipe.
[0008] Preferably, both the connecting pipe and the drain pipe are equipped with electromagnetic valves.
[0009] Preferably, the capsule is made of one-piece nylon molding.
[0010] Preferably, the inner wall of the groove has a gradually inclined structure, forming an inclined surface that is continuously distributed around the circumference of the groove; the inclined surface is set with the collection part as the lowest point, and is inclined downward along the inner wall of the groove from the opening edge of the groove to the collection part; the upper end of the inclined surface smoothly transitions to the opening edge of the groove, the lower end smoothly connects to the side wall of the collection part, and the surface of the inclined surface is a smooth planar structure.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention features a recessed area with a waste collection section on one side of the toilet bowl, which concentrates waste and prevents it from spreading. The water inlet pipe, in conjunction with a slow-flow channel, guides water gently into the bowl, creating a slow-flow area that covers the inner wall of the recess, effectively reducing waste adhesion. A mounting plate on the toilet bowl provides a stable mounting surface for the bladder, and its top opening precisely matches the bladder's installation position, ensuring it doesn't easily shift during use and enhancing structural stability. A connecting pipe on one side of the bladder connects to the water inlet pipe, allowing external water to flexibly fill the bladder. Once filled, the bladder naturally inflates according to the body's contours, closely fitting the contact area and effectively filling the gap between the traditional toilet bowl and the body, fundamentally reducing the possibility of waste leakage and significantly reducing cleaning workload. The soft texture of the inflated bladder cushions the hard contact between the body and the toilet bowl, significantly improving comfort and preventing pressure and damage to the skin from prolonged use.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Reference Figures 1-5 A splash-proof, internal flow type toilet structure includes a toilet body 1, a groove 2 is provided on one side of the toilet body 1, and a stool collection part 3 is provided at the bottom of the groove 2. A water inlet pipe 4 is provided on one side of the toilet body 1, and an installation groove 5 is provided on the outer periphery of the toilet body 1. A slow-flow channel device is provided in the installation groove 5. The water inlet end of the slow-flow channel device is connected to the water inlet pipe 4, and the water outlet end is set towards the inner wall of the groove 2. It is used to form a slow-flow area on the outer side of the inner wall of the groove 2, guide the water flow along the inner wall of the groove 2 and cover the inner wall of the groove 2. The toilet body 1 is provided with an installation plate 6, the top of the installation plate 6 is provided with an opening 7, a bladder 8 is installed in the opening 7, a connecting pipe 9 is provided on one side of the bladder 8, and one side of the connecting pipe 9 is connected to the water inlet pipe 4. The water inlet pipe 4 can selectively supply water to the slow-flow channel device, or fill the bladder 8 with water through the connecting pipe 9. When water is filled into the bladder 8, the bladder 8 can bulge upward along the opening 7 and fit against the part of the human body that is in contact with it.
[0016] When in use, this device features a groove 2 with a waste collection section 3 on one side of the toilet bowl body 1, which collects waste and prevents it from spreading randomly. The water inlet pipe 4, in conjunction with the slow-flow channel device, guides water to slowly flow into the toilet bowl, forming a slow-flow area that covers the inner wall of the groove 2, effectively reducing waste adhesion. The mounting plate 6 on the toilet bowl body 1 provides a stable mounting carrier for the bladder 8, and its top opening 7 precisely matches the installation position of the bladder 8, ensuring that the bladder 8 is not easily displaced during use, resulting in stronger structural stability. The connecting pipe 9 on one side of the bladder 8 is connected to the water inlet pipe 4, allowing an external water source to flexibly fill the bladder 8 with water through the water inlet pipe 4. After filling, the bladder 8 naturally bulges according to the contours of the human body, closely fitting the contact area with the human body, effectively filling the gap between the traditional toilet bowl and the human body, fundamentally reducing the possibility of waste leakage, and greatly reducing the amount of cleaning work. The bulging bladder 8 is soft in texture, which can cushion the hard contact between the human body and the toilet bowl, significantly improving the comfort during use and avoiding pressure and damage to the skin caused by prolonged use.
[0017] In the example of this application, the slow-flow channel device includes a water outlet pipe 10 disposed in the mounting groove 5, the water inlet pipe 4 being connected to the water outlet pipe 10, and a plurality of water outlets 11 being provided on the inner wall of the groove 2, and the plurality of water outlets 11 being connected to the water outlet pipe 10 through pipelines.
[0018] As a preferred example of this utility model, the slow-flow channel device uses an outlet pipe 10 in the installation groove 5 connected to an inlet pipe 4, and several outlets 11 on the inner wall of the groove 2 are connected to the outlet pipe 10 through pipelines, which can evenly distribute the water flow to each outlet 11, so that the water flow flows out from multiple positions on the inner wall of the groove 2, forming a more comprehensive and uniform slow-flow coverage area, further enhancing the flushing effect on the inner wall of the groove 2, reducing dirt residue, and at the same time, the uniform water flow can also more effectively play a buffering and splash-proof role, improving the splash-proof and cleaning effect.
[0019] In the example of this application, a drain pipe 12 is provided on one side of the bladder 8, and one end of the drain pipe 12 is connected to the water outlet pipe 10.
[0020] As a preferred example of this utility model, the drain pipe 12 on one side of the bladder 8 is connected to the water outlet pipe 10, so that the water in the bladder 8 can be drained into the water outlet pipe 10 through the drain pipe 12. This makes it easy to drain the water in the bladder 8 after use, so that the bladder 8 can be restored to its original state for easy storage and next use. The drained water can enter the water outlet pipe 10 to participate in the flushing of the toilet, realizing the rational use of water resources and improving the convenience of using the toilet and the water-saving effect.
[0021] In the example of this application, both the connecting pipe 9 and the drain pipe 12 are equipped with solenoid valves 13.
[0022] As a preferred example of this utility model, the electromagnetic valve 13 installed on the connecting pipe 9 and the drain pipe 12 can precisely control the filling and draining process of the bladder 8. By controlling the valve on the connecting pipe 9, the amount of water entering the bladder 8 can be adjusted to meet the needs of different body fits. By controlling the valve on the drain pipe 12, the water in the bladder 8 can be discharged at any time. The operation is flexible and convenient, with a high degree of automation, which improves the convenience and controllability of using the bedpan.
[0023] In the example of this application, the capsule 8 is integrally molded from nylon (or polyvinyl chloride).
[0024] As a preferred example of this utility model, the bladder body 8 is made of one-piece nylon. Nylon material has good flexibility, wear resistance and sealing properties. The one-piece molding process can ensure that the bladder body 8 has no splicing gaps, avoid water leakage, and at the same time enhance the structural strength and service life of the bladder body 8. This makes the bladder body 8 less prone to damage during repeated use of filling and deflating, and ensures the stable performance of the bladder body 8 in conforming to the human body.
[0025] In the example of this application, the inner wall of the groove 2 has a gradually inclined structure, forming an inclined surface 14 that is continuously distributed around the circumference of the groove 2; the inclined surface 14 is set with the collection part 3 as the lowest point, and is inclined downward along the inner wall of the groove 2 from the edge of the opening 7 of the groove 2 towards the collection part 3; the upper end of the inclined surface 14 smoothly transitions to the edge of the opening 7 of the groove 2, and the lower end smoothly connects to the side wall of the collection part 3, and the surface of the inclined surface 14 is a smooth planar structure with an inclination angle of 15°-45° (that is, the angle α between the inclined surface 14 and the horizontal plane satisfies 15°≤α≤45°).
[0026] As a preferred example of this utility model, the gradually inclined structure of the inner wall of the groove 2 forms a continuous inclined surface 14 around the circumference, with the collection part 3 as the lowest point, and inclined downward from the edge of the opening 7 of the groove 2 towards the collection part 3. This inclined angle design can utilize gravity to guide the waste (including solid waste and liquid) to slide quickly and smoothly along the inclined surface 14 towards the collection part 3, avoiding the waste from lingering on the inner wall of the groove 2, reducing the difficulty of cleaning. The smooth transition design avoids the problem of waste getting stuck or scratched due to sharp edges. The smooth surface further reduces the adhesion of waste. The continuous inclined inner wall structure, combined with the water flow coverage of the slow water flow channel, makes the water flow more closely fit the inner wall when it flows along the inclined surface 14, reducing the impact angle between the water flow and the inner wall, further reducing the probability of splashing. At the same time, the inclined surface 14 guides the waste to quickly gather, shortening the residence time of the waste in the groove 2, indirectly reducing the risk of splashing.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
