Description

Technical Field

[0001] This invention relates to the field of bathroom equipment performance testing technology, and in particular to a toilet flushing force testing device and method. Background Technology

[0002] Water is essential to our daily lives, sustaining our lives and playing a vital role in production and daily life. However, my country's water resources are extremely scarce, making water conservation an urgent priority. Related data shows that toilet water consumption accounts for approximately 60% to 70% of domestic water usage, with toilets accounting for more than one-third of that. Therefore, optimizing toilet plumbing to reduce flush volume is crucial.

[0003] Currently, a toilet flushing force testing method with application publication number CN 111413020 A, by limiting two distance parameters, can ensure that the distance between the water jet impacting the force-bearing plate from the toilet nozzle is consistent, and the measured flushing force index can be compared between different toilets. Furthermore, the positioning block is lockably slidable to meet the position adjustment requirements relative to the positioning rod; the positioning rod is also lockably slidable to meet the position adjustment requirements relative to the support rod. However, existing testing methods cannot intuitively reflect the actual flushing performance of the toilet, nor its ability to suction waste from the toilet bowl. The problem of toilets wasting a large amount of fresh water during use remains, and most siphon tubes are opaque, making it impossible to directly observe the water flow pattern and vortex position within the siphon tube. Summary of the Invention

[0004] The technical problem solved by this invention is that existing detection methods are difficult to intuitively reflect the actual flushing situation of the toilet and the ability to suck up the sewage inside the toilet. The problem of the toilet wasting a lot of fresh water during use still exists, and most of the siphon tubes are not transparent, so it is impossible to intuitively observe the water flow pattern and vortex position inside the siphon tube.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a toilet flushing force testing device, comprising a toilet body, the toilet body including a water tank, a toilet seat, a siphon pipe, a bucket body, a water outlet pipe, a water inlet pipe, and a support base, the bottom of the water tank being connected to the bucket body, the top of the bucket body being hinged to the toilet seat, the bottom outer wall of the bucket body being fixedly connected to the support base, and the bottom of the bucket body being sequentially connected to the water inlet pipe, the siphon pipe, and the water outlet pipe; and an adjustment assembly, the adjustment assembly including a telescopic rod, an inner tube, and a fixing plate, one end of the telescopic rod being fixedly connected to the inner wall of the water inlet pipe, the other end of the telescopic rod being fixedly connected to one side of the fixing plate, the other side of the fixing plate being fixedly connected to the outer wall of the inner tube, and both ends of the inner tube being fixedly connected to the inner wall of the water inlet pipe.

[0006] As a preferred embodiment of the toilet flushing force test device of the present invention, the telescopic rod is provided in more than 4 sets and is arranged in a circular shape around the axis of the water inlet pipe.

[0007] In a preferred embodiment of the toilet flushing force testing device of the present invention, the adjusting assembly further includes a cylinder, a piston head, an internally threaded pipe, a screw, and a fixing ring. The cylinder is fixedly connected to the outer wall of the water inlet pipe, and the inside of the cylinder is connected to the fixing ring. The fixing ring is fixedly connected to the inner wall of the water inlet pipe, and the inside of the fixing ring is hollow and connected to a telescopic rod. The piston head is slidably connected to the inner wall of the cylinder, and one end of the piston head is rotatably connected to the screw. The screw is threadedly connected to the inner wall of the internally threaded pipe, and the outer wall of the internally threaded pipe is fixedly connected to the cylinder.

[0008] In a preferred embodiment of the toilet flushing force experimental device of the present invention, the end of the screw away from the piston head is fixedly connected to a rotating disk.

[0009] In a preferred embodiment of the toilet flushing force experimental device of the present invention, the siphon pipe is made of transparent material.

[0010] A method for testing the flushing power of a toilet includes setting up a fixed-ball flushing test and a fixed-water-ball flushing test; collecting experimental data; adjusting the diameter of the inner pipe; repeating the fixed-ball flushing test and the fixed-water-ball flushing test; and screening the experimental data.

[0011] As a preferred embodiment of the toilet flushing force test method described in this invention, the test data includes the water flow velocity at the inlet of the water inlet pipe and the diameter of the inner pipe.

[0012] As a preferred embodiment of the toilet flushing force test method described in this invention, the fixed-ball flushing test includes placing the same number of experimental balls inside the toilet and recording the water consumption when all balls are flushed; adjusting the diameter of the inner tube and repeating the fixed-ball flushing test; and selecting the inner tube diameter value and the inlet water flow velocity v of the test when all balls are flushed with the least amount of water.

[0013] As a preferred embodiment of the toilet flushing force test method described in this invention, the constant water flushing ball test includes placing the same number of small balls in the toilet bowl at the beginning of each test, and flushing away the number of small balls after a fixed amount of water in the tank is used up; adjusting the diameter of the inner tube and repeating the constant water flushing ball test; selecting the inner tube diameter value and the water flow velocity v at the inlet of the test that flushed away the most small balls; by comparing the water flow velocity v and the water flow velocity v, selecting the inner tube diameter with the smaller water flow velocity as the inlet pipe diameter.

[0014] As a preferred embodiment of the toilet flushing force test method described in this invention, the adjustment of the inner tube diameter includes: rotating the rotating disc.

[0015] The beneficial effects of this invention are as follows: By changing the diameter of the inner pipe, the flow rate of the water in the inlet pipe can be adjusted, allowing for the selection of the optimal pipe diameter value for flushing performance that is less prone to clogging. This ensures the effective suction of waste inside the toilet, making experiments more convenient and faster. It eliminates the need to replace inlet pipes and siphon pipes of different diameters, enabling actual flushing performance tests on the toilet model. This not only helps verify the results of theoretical design and numerical calculations, but also allows for observation of the flow and remaining state of the small ball, reflecting the flushing performance and waste removal capacity of the toilet pipe. Furthermore, the flow pattern and vortex position can be observed through the siphon pipe, providing concrete evidence for the simulation experiment. Attached Figure Description

Detailed Implementation

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1

[0025] Reference Figures 1 to 5 According to one embodiment of the present invention, a toilet flushing force testing device is provided, comprising: a toilet body 100, the toilet body 100 including a water tank 101, a toilet seat 102, a siphon pipe 103, a bucket body 104, a water outlet pipe 105, a water inlet pipe 106, and a support base 107. The bottom of the water tank 101 is connected to the bucket body 104, the top of the bucket body 104 is hinged to the toilet seat 102, the bottom outer wall of the bucket body 104 is fixedly connected to the support base 107, and the bottom of the bucket body 104 is sequentially connected to the water inlet pipe 106, the siphon pipe 103, and the water outlet pipe 105.

[0026] In this preferred embodiment, the water tank 101 is used for water storage, and the capacity of the water tank 101 determines the amount of water used for one flush. The bucket body 104 is used to hold waste, and the waste and water in the bucket body 104 are discharged sequentially through the inlet pipe 106, the siphon pipe 103, and the outlet pipe 105. The support base 107 provides support.

[0027] An adjusting component 200 includes a telescopic rod 201, an inner tube 202, and a fixing plate 203. One end of the telescopic rod 201 is fixedly connected to the inner wall of the water inlet pipe 106, and the other end is fixedly connected to one side of the fixing plate 203. The other side of the fixing plate 203 is fixedly connected to the outer wall of the inner tube 202, and both ends of the inner tube 202 are fixedly connected to the inner wall of the water inlet pipe 106. By changing the diameter of the inner tube 202, the flow rate of water in the water inlet pipe 106 can be adjusted, allowing for the selection of the optimal flushing performance and the reduction of clogging. This makes the experiment more convenient and faster, eliminating the need to replace the water inlet pipe 106 and siphon pipe 103 with different diameters. If the adjusting component 200 is applied to a product, the toilet can be unclogged by adjusting the diameter of the inner tube 202. For example, first reducing the diameter of the inner tube 202 compresses the radial dimension of the blockage, and then increasing the diameter of the inner tube 202 creates a gap between the blockage and the inner wall of the inner tube 202, allowing the blockage to be flushed away.

[0028] In this preferred embodiment, the telescopic rod 201, by extending or retracting, can move the fixed plate 203. The fixed plate 203, in turn, moves the wall of the inner tube 202, causing the diameter of the inner tube 202 to contract or expand, thereby changing the diameter of the inner tube 202. The inner tube 202 can be approximated as a circle. The inner tube 202 is preferably made of elastic rubber tubing.

[0029] The telescopic rod 201 is provided in four or more sets and is arranged in a circular pattern around the axis of the water inlet pipe 106.

[0030] In this preferred embodiment, multiple sets of telescopic rods 201 are set, and the fixing plate 203 is set corresponding to the telescopic rods 201. The more telescopic rods 201 are set, the closer the inner tube 202 can be to a circle.

[0031] The adjusting assembly 200 further includes a cylinder 204, a piston head 205, an internally threaded pipe 206, a screw 207, and a retaining ring 208. The cylinder 204 is fixedly connected to the outer wall of the water inlet pipe 106, and the cylinder 204 is internally connected to the retaining ring 208. The retaining ring 208 is fixedly connected to the inner wall of the water inlet pipe 106, and the retaining ring 208 is hollow and connected to the telescopic rod 201. The piston head 205 is slidably connected to the inner wall of the cylinder 204. One end of the piston head 205 is rotatably connected to the screw 207. The screw 207 is threadedly connected to the inner wall of the internally threaded pipe 206, and the cylinder 204 is fixedly connected to the outer wall of the internally threaded pipe 206.

[0032] In this preferred embodiment, rotating the screw 207 causes it to move radially under the action of the internal threaded tube 206. The screw 207 drives the piston head 205 to slide on the inner wall of the cylinder 204, compressing the air inside the cylinder 204. The air inside the cylinder 204 enters the fixed ring 208 and then the telescopic rod 201, causing the telescopic rod 201 to extend towards the axis of the inner tube 202. The fixed plate 203 releases the tension on the inner tube 202, causing the inner tube 202 to contract under its own elastic force. The piston head 205 slides away from the fixed ring 208 on the inner wall of the cylinder 204, creating a negative pressure inside the cylinder 204. This causes the telescopic rod 201 to contract and shorten towards the axis of the inner tube 202. The fixed plate 203 overcomes the elastic force of the inner tube 202, pulling it to expand its diameter.

[0033] The end of the screw 207 away from the piston head 205 is fixedly connected to the rotating disk 209.

[0034] In this preferred embodiment, the rotating disk 209 facilitates the rotation of the screw 207.

[0035] The siphon pipe 103 is made of transparent material.

[0036] In this embodiment, the preferred method facilitates intuitive observation of the flow pattern of water within the siphon.

[0037] Example 2

[0038] Reference Figures 1 to 5 This is another embodiment of the present invention. Unlike the first embodiment, this embodiment provides a toilet flushing force test method. In order to verify and explain the technical effect of the method, this embodiment uses a traditional technical solution to compare and test with the method of the present invention, and compares the test results with scientific demonstration methods to verify the real effect of the method.

[0039] S1: Set up a fixed ball flushing test and a fixed water flushing test;

[0040] S2: Collect experimental data;

[0041] The experimental data include the water flow velocity at the inlet 1061 on the inlet pipe 106 and the diameter of the inner pipe 202.

[0042] The fixed-ball flushing test involves placing the same number of experimental balls inside the barrel 104 and recording the amount of water used when all the balls are flushed down.

[0043] 80 solid, submersible balls were placed inside the barrel 104. The water volume in the water tank 101 was changed multiple times to find the water volume that would flush all the balls out. The flow pattern and vortex position in the pipe were observed.

[0044] Adjust the diameter of the inner pipe 202 and repeat the fixed ball flushing test;

[0045] In the experiment to determine the flushing method that minimizes water consumption when all balls are flushed, the inner diameter of the inner pipe 202 and the water flow velocity v1 at the inlet 1061 are used. The water flow velocity v1 reflects flushing power; a higher v1 indicates stronger flushing. The inner pipe diameter 202 can be adjusted multiple times while maintaining flushing power to find the diameter corresponding to the minimum water consumption, thus improving the toilet's water-saving performance.

[0046] The constant water flushing ball experiment includes placing the same number of small balls in the toilet 104 at the beginning of each experiment, and the number of small balls flushed away after a fixed amount of water in the water tank 101 is used up.

[0047] 200 solid, submersible balls are placed inside the bucket 104. Without changing the water volume in the tank 101, the diameter of the inner pipe 202 is adjusted multiple times to find the diameter that allows the most balls to be flushed out. Alternatively, the angle between the two ends of the siphon pipe 103 and the outlet pipe 105 and inlet pipe 106 can be adjusted to reduce internal resistance and find the optimal angle. The flow pattern and vortex position within the pipe are observed. By repeatedly adjusting the diameter of the inner pipe 202, the maximum flushing capacity can be achieved with a certain amount of water.

[0048] Adjust the diameter of the inner pipe 202 and repeat the constant water jet test;

[0049] The diameter gradient of the inner pipe 202 can be set in increments of 0.1 mm. After each adjustment, 80 solid, submersible balls are placed inside the bowl 104. The water volume in the tank 101 is varied multiple times to find the water volume that flushes out all the balls. The flow pattern and vortex position within the pipe are observed. The constant-ball flushing test and the constant-water-ball flushing test can be conducted on toilet models with different requirements. For example, a constant-ball flushing test can be used for toilets with high water-saving performance requirements, while a constant-water-ball flushing test can be used for toilets with high flushing capacity requirements. Alternatively, the same toilet model can be tested. In this case, either the constant-water-ball flushing test or the constant-ball flushing test can be performed first. Subsequent tests can use the inner pipe 202 diameter data obtained from the previous test, eliminating the need for further adjustment of the inner pipe 202 diameter. This speeds up the experiment and reduces experimental variables.

[0050] When selecting the experiment that washes away the most balls, the inner diameter of the inner tube 202 and the water flow velocity v2 at the inlet 1061 are used. The water flow velocity v2 can represent the flushing ability, and the larger the water flow velocity v2, the stronger the flushing ability.

[0051] By comparing water flow velocities v1 and v2, the inner pipe diameter 202 with the lower water flow velocity was selected as the inlet pipe diameter 106. When testing the same toilet model, both a fixed-ball flushing test and a fixed-water-ball flushing test were performed simultaneously. The water flow velocities v1 and v2 were obtained, and the inner pipe diameter 202 with the lower water flow velocity was selected. Because a larger inner pipe diameter 202 results in a faster water flow rate for the same volume of water, but also reduces the flushing time within the pipe, making it harder to flush away deposits on the inner wall. These deposits require a longer flushing time; therefore, for water conservation purposes, the inner pipe diameter 202 with the lower water flow velocity was selected.

[0052] S3: Adjust the diameter of the inner tube 202;

[0053] The telescopic rod 201 can move the fixed plate 203 by extending and retracting, and the fixed plate 203 can move the wall of the inner tube 202, causing the diameter of the inner tube 202 to contract or expand, thereby changing the diameter of the inner tube 202.

[0054] S4: Repeated fixed-ball flushing test and fixed-water flushing test;

[0055] S5: Screen the experimental data.

[0056] The diameter gradient of the inner pipe 202 can be set in increments of 0.1 mm. After each adjustment of the pipe diameter, a constant ball flushing test and a constant water flushing ball test are performed. The pipe diameter of the inner pipe 202 with the smaller water flow velocity in each group of experiments is selected as the pipe diameter of the siphon pipe 103, the outlet pipe 105, and the inlet pipe 106.

[0057] Then, by adjusting the angles between the two ends of the siphon pipe 103 and the outlet pipe 105 and inlet pipe 106, the fixed-ball flushing test or the fixed-water-ball flushing test can be repeated. This allows for the search for or verification of the optimal angles between the two ends of the siphon pipe 103 and the outlet pipe 105 and inlet pipe 106. This enables actual flushing performance testing of the toilet model, which not only helps verify the results of theoretical design and numerical calculations, but also reflects the flushing performance and sewage discharge capacity of the toilet pipe by observing the flow and residue of the small ball. Furthermore, the water flow pattern and vortex position can be clearly observed through the transparent siphon pipe, providing concrete evidence for the simulation experiment.

[0058] The adjustment of the inner tube 202 diameter includes: rotating the rotating disk 209, which drives the rotating screw 207. Under the action of the internal threaded tube 206, the screw 207 moves radially, and the screw 207 drives the piston head 205 to slide on the inner wall of the cylinder 204, compressing the air inside the cylinder 204. The air inside the cylinder 204 enters the fixed ring 208 and then enters the telescopic rod 201. The telescopic rod 201 extends towards the axis of the inner tube 202, and the fixed plate 203 releases the tension on the inner tube 202. Under the action of its own elasticity, the inner tube 202 diameter contracts. The piston head 205 slides away from the fixed ring 208 on the inner wall of the cylinder 204, which will create a negative pressure inside the cylinder 204. The telescopic rod 201 retracts and shortens towards the axis of the inner tube 202. The fixed plate 203 overcomes the elasticity of the inner tube 202 and pulls the inner tube 202 to expand its diameter.

[0059] It should be recognized that embodiments of the present invention can be implemented or carried out by computer hardware, a combination of hardware and software, or by computer instructions stored in a non-transitory computer-readable storage medium. The method can be implemented using standard programming techniques—including a non-transitory computer-readable storage medium configured with a computer program, wherein such a storage medium causes the computer to operate in a specific and predefined manner—according to the methods and drawings described in the specific embodiments. Each program can be implemented in a high-level procedural or object-oriented programming language to communicate with the computer system. However, if desired, the program can be implemented in assembly or machine language. In any case, the language can be a compiled or interpreted language. Furthermore, for this purpose, the program can run on a programmed application-specific integrated circuit (ASIC).

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
