Description

Technical Field

[0001] The utility model relates to a water-saving toilet, in particular to a water-saving toilet with a floating ball automatically closing a lower drain port. Background Art

[0002] Rural toilet reform, despite its rapid progress, has suddenly slowed. The primary problem lies in technological bottlenecks. While many rural areas have access to water for flushing, most rely on the principle that more irrigation means more harvest. Consequently, few rural residents are willing to use the water-consuming urban toilet flushing method. For example, in rural northern my country, a custom is to make a paper ox for the funeral of a deceased woman and give it water to drink from washing dishes and pots. This is said to be because women waste water washing dishes and pots during their lifetime, so giving the ox water to avoid wasting water is a way of alleviating blame. This demonstrates the preciousness of water in rural areas. Therefore, rural my country urgently needs water-saving toilets that significantly reduce the water consumption of urban toilets. There is a float-type toilet with document number CN103147502A, which does not have a trap. It is an improvement on a toilet with a trap. The improvement is to remove the trap of the existing toilet, so that the toilet's funnel-shaped drain outlet is connected to the sewer. The improved drain outlet is circular, and the shape of the toilet's inner wall remains unchanged, with the surface finish of the inner wall unchanged. A float is placed in the toilet, which closes the drain outlet. The float floats on the water surface of the toilet's inner wall. The outer surface of the float is provided with a mesh of fine lines, and the pits formed by the fine lines can attract some water. Although feces will fall directly onto the float when using the toilet, and although flushing the toilet before using the toilet can prevent the float from sticking to the water and help flush it clean, the excess water used in the flushing still does not meet the objective conditions of water conservation in rural areas. Therefore, the vast rural areas in my country that are short of water and cherish water are still in urgent need of a water-saving toilet that can further significantly save water. Utility Model Content

[0003] The present utility model aims to overcome the above-mentioned drawbacks of the prior art by providing a water-saving toilet with a float that automatically closes the lower outlet. While the toilet also does not have a trap, it utilizes a float that automatically closes the lower outlet. This feature allows the float to self-clean without first flushing the float to prevent it from getting wet, allowing for flushing and odor isolation with only a small amount of water.

[0004] To achieve the above-mentioned purpose, the utility model provides a water-saving toilet with a float that automatically closes the lower drain outlet. The toilet has a flushing hole at the top that flows into its elongated collecting bucket, and is characterized in that a circular funnel-type lower drain outlet with a movable circular sealing float is provided near one end of the elongated collecting bucket, the elongated collecting bucket includes a lower groove sloped lower drain wall from the distal end to the circular funnel-type lower drain outlet, and a lower groove sloped upper drain wall is provided in the elongated collecting bucket from the end near the lower drain outlet to the middle; the gap distance between the inner extending end of the upper drain wall and the lower drain wall below it is less than the diameter of the float, the float is an elastic float that passes through the gap under extrusion, or the elongated collecting bucket is provided with a float inlet and outlet with a sealing valve above the circular funnel-type lower drain outlet; or the minimum gap distance between the inner extending end of the upper drain wall and the lower drain wall below it is greater than the diameter of the float, the inner extending end of the upper drain wall is provided with a downwardly extending float baffle, and a flushing channel is provided between the lower end of the float baffle and the lower drain wall. In this way, during flushing, the float ball of the closed circular funnel-shaped lower outlet can be floated to the upper space between the upper flushing wall and the elongated collecting bucket. After the flushing flow rushes into the lower outlet, the float ball can return to the original state of the closed circular funnel-shaped lower outlet, thus achieving the lower outlet closure before and after flushing. By eliminating the odor-isolating water storage bay that reduces the efficiency of flushing, it can significantly improve the efficiency of flushing and drainage while achieving significant water savings. In addition, since the float can rely on "the distance between the inner extending end of the upper flushing wall and the lower flushing wall below it is smaller than the diameter of the float, the float is an elastic float or a long collecting bucket that passes through the said gap under extrusion, and a float entrance and exit with a sealing valve is provided above the circular funnel-type lower discharge outlet; or the minimum distance between the inner extending end of the upper flushing wall and the lower flushing wall below it is greater than the diameter of the float, the inner extending end of the upper flushing wall is installed with a downward extending float baffle, and there is a flushing channel between the lower end of the float baffle and the lower flushing wall". During the floating process, the float will be strictly restricted in the space above the circular funnel-type lower discharge outlet, effectively ensuring that the float does not run out of the said gap, and more importantly, ensuring that the circular funnel-type lower discharge outlet can be securely closed when falling back. In particular, because the float is strictly confined under the sloped upper flushing wall of the lower trough, feces will never fall directly on the float, solving the problem of the existing technology that feces falling directly on the float are easy to stick to, and the extra water consumption of flushing water must be used to wet the float first; and because the flushing water flow always encounters the float before the flushed feces, causing the float to bounce up, the chance of the float encountering feces during flushing is very small, and even if it does, it is more likely to be sticky before encountering it again. Therefore, the float is very unlikely to be contaminated by feces. It has the advantages of no water trap for flushing resistance and water consumption, and the float is not easily contaminated during flushing, realizing flushing and odor isolation with only a small amount of water, high flushing efficiency, good odor isolation, and significant water saving, which is particularly suitable for rural toilet reform.

[0005] As an optimization, when the distance between the inner extension end of the lower trough sloped upper flushing wall and the lower flushing wall below it is less than the diameter of the float, the downward slope of the inner extension front section of the lower trough sloped upper flushing wall is greater than the downward slope of its base section. This is beneficial for resisting the return flow of the flushing and also for blocking the return airflow of the flushing and increasing the downward flushing force.

[0006] As an optimization, the inner angle between the inner extension end of the upper flushing wall and the lower flushing wall is greater than 90 degrees, which is more conducive to preventing backflow and increasing the downward flushing force.

[0007] As an optimization, the inner end of the upper flush wall is installed in a loose or disassembled manner to install the downward floating ball baffle, and the diversion effect can be increased after adjusting the angle; or the inner end of the upper flush wall is hingedly provided with the naturally drooping downward floating ball baffle, which has a better flow-adapting effect.

[0008] As an optimization, the downward-extending float baffle installed by loosening or disassembling is tilted from top to bottom toward the base side of the upward flushing wall when installed and fixed, which can increase the diversion effect and thus reduce the side effects of the baffle belt.

[0009] As an optimization, at least the lower section of the downwardly extending float baffle is in the shape of an oblique downward convex arc with the concave surface facing the base side of the upward flushing wall.

[0010] As an optimization, the downward-extending float baffle installed by loosening or disassembling is a float baffle with an anti-stick surface, which is beneficial to reducing flushing resistance while preventing sticking; the naturally drooping downward-extending float baffle is a float baffle with an anti-stick surface and a specific gravity greater than water, which is beneficial to preventing excessive impact while preventing sticking, thereby avoiding the downward-extending float baffle being light in weight and being excessively flushed upward and losing its function of blocking the float.

[0011] As an optimization, the toilet can be a squat toilet or a seat toilet. Squat toilets are suitable for rural public toilet renovations and adapt to water shortages in rural areas. Farmers can choose between squat toilets and seat toilets based on their specific circumstances, such as squat toilets for daily use and seat toilets for emergency use at night or in unusual weather conditions.

[0012] As an optimization, the squat toilet is provided with a rear flushing hole facing the downward flushing wall and a front flushing hole facing the upward flushing wall, which can further save water; the toilet is provided with a top inner ring flushing hole, which is conducive to ensuring the cleanliness of the toilet after flushing.

[0013] As an optimization, toilets feature a circular flush channel connected to the flush hole at the upper ring end of their elongated collection hopper. Squatting toilets feature a water inlet for connecting to the flushing pipe at a low position at the rear end of the circular flush channel, allowing the inlet and connected pipes to be laid beneath the decorative floor. Toilets feature a water inlet at the rear end of the circular flush channel for connecting to the flushing pipe or flush tank. Connecting the flushing pipe helps insulate the pipe and the connected flush tank from freezing in winter.

[0014] This new toilet mainly consists of a main body, a float and a baffle. The toilet drop area is located at the back, close to the main flush outlet, which not only has a good flushing effect, but also is not easy to collect dirt. It is particularly water-saving, requiring only one flush after defecation, and only 1-2 liters of water are needed, which saves 67-83% of water compared to the national standard of 6 liters. During normal use, the float will automatically float up due to buoyancy, and the dirt will flow into the drain channel through the circular funnel-shaped lower outlet. After flushing is completed, the float will automatically fall and close the lower outlet, achieving an unconditional deodorization effect. The float is made of anti-stick material and is not easy to collect dirt or emit odors. It is not easy to damage, durable, easy to maintain, low in cost, has a good deodorization and deodorization effect, is particularly water-saving, and is suitable for promotion and application in any water-scarce area.

[0015] After adopting the above technical scheme, the water-saving toilet with a float that automatically closes the lower drain outlet of the utility model has the advantages of no flushing resistance and water consumption of a water trap, and the float is not easily contaminated during flushing, so only a small amount of water is used for flushing and the float is used for odor isolation. It has high flushing efficiency, good odor isolation, and greatly saves water, which is particularly suitable for rural toilet reform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] Example 1, as Figure 1As shown, the utility model of the water-saving toilet with a float automatically closing the lower discharge port is a toilet 1 with a flushing hole at the top thereof flowing to its elongated collecting bucket 10, a circular funnel-type lower discharge port 3 with a movable circular sealing float 2 is provided near one end of the elongated collecting bucket 10, the elongated collecting bucket 10 includes a lower groove sloped lower flushing wall 11 extending from the distal end to the circular funnel-type lower discharge port 3, and a lower groove sloped upper flushing wall 12 extending from the lower discharge port end to the middle portion is provided in the elongated collecting bucket 10; the upper flushing wall 12 The opening distance between the inner extension end and the lower flushing wall 11 below it is smaller than the diameter of the float 2. The float 2 is an elastic float 2 that passes through the opening under extrusion. Alternatively, the elongated collecting bucket is provided with a float inlet and outlet with a sealing valve above the circular funnel-type lower discharge port. Alternatively, the opening distance between the inner extension end of the upper flushing wall and the lower flushing wall below it is larger than the diameter of the float. The inner extension end of the upper flushing wall is provided with a downwardly extending float baffle, and a flushing channel is provided between the lower end of the float baffle and the lower flushing wall. In this way, during flushing, the float that closes the circular funnel-type lower discharge port can be flushed to the upper space between the upper flushing wall and the elongated collecting bucket. After the flushing flow rushes into the lower discharge port, the float can return to the initial state of the closed circular funnel-type lower discharge port, thereby achieving closure of the lower discharge port before and after flushing. Since the odor-isolating water storage bay that reduces the efficiency of flushing is eliminated, it can significantly improve the flushing efficiency while achieving substantial water saving. In addition, since the float can rely on "the distance between the inner extending end of the upper flushing wall and the lower flushing wall below it is smaller than the diameter of the float, the float is an elastic float or a long collecting bucket that passes through the said gap under extrusion, and a float entrance and exit with a sealing valve is provided above the circular funnel-type lower discharge outlet; or the minimum distance between the inner extending end of the upper flushing wall and the lower flushing wall below it is greater than the diameter of the float, the inner extending end of the upper flushing wall is installed with a downward extending float baffle, and there is a flushing channel between the lower end of the float baffle and the lower flushing wall". During the floating process, the float will be strictly restricted in the space above the circular funnel-type lower discharge outlet, effectively ensuring that the float does not run out of the said gap, and more importantly, ensuring that the circular funnel-type lower discharge outlet can be securely closed when falling back. In particular, because the float is strictly confined under the sloped upper flushing wall of the lower trough, feces will never fall directly on the float, solving the problem of the existing technology that feces falling directly on the float are easy to stick to, and the extra water consumption of flushing water must be used to wet the float first; and because the flushing water flow always encounters the float before the flushed feces, causing the float to bounce up, the chance of the float encountering feces during flushing is very small, and even if it does, it is more likely to be sticky before encountering it again. Therefore, the float is very unlikely to be contaminated by feces. It has the advantages of no water trap for flushing resistance and water consumption, and the float is not easily contaminated during flushing, realizing flushing and odor isolation with only a small amount of water, high flushing efficiency, good odor isolation, and significant water saving, which is particularly suitable for rural toilet reform.

[0018] Specifically, when the distance between the inner end of the lower trough sloped upper flushing wall 12 and the lower flushing wall 11 below it is less than the diameter of the float 2, the downward slope of the inner front section of the lower trough sloped upper flushing wall 12 is greater than the downward slope of its base section. The inner angle between the inner end of the upper flushing wall 12 and the lower flushing wall 11 is greater than 90 degrees. The toilet 1 is a squat toilet, which is provided with a rear flushing hole flushing the lower flushing wall 11 and a front flushing hole flushing the upper flushing wall 12. The toilet 1 is provided with an annular flushing channel leading to the flushing holes at the upper end ring portion of its elongated collecting hopper 10. The squat toilet is provided with a water inlet 9 for connecting to the flushing pipeline at a low position at the rear end of the annular flushing channel.

[0019] Example 2, as Figure 2 As shown, the difference between the water-saving toilet with a float ball automatically closing the lower discharge outlet of the present invention and the above-mentioned embodiment 1 is that the elongated collecting bucket 10 is provided with a float ball inlet and outlet with a sealing valve 4 above the circular funnel-shaped lower discharge outlet 3.

[0020] Example 3, as Figure 3 As shown, the present invention's water-saving toilet with a float that automatically closes the lower drain outlet differs from the aforementioned first embodiment in that the distance between the inner end of the upper drain wall 12 and the lower drain wall 11 below it is greater than the diameter of the float 2. A downwardly extending float baffle 5 is mounted on the inner end of the upper drain wall 12, with a drain passage defined between the lower end of the float baffle 5 and the lower drain wall 11. The lowered float baffle 5 is mounted on the inner end of the upper drain wall 12 in a loose or disassembled manner. While mounted, the lowered float baffle 5 tilts from top to bottom toward the base of the upper drain wall 12. This loose or disassembled lowered float baffle 5 has a non-stick surface.

[0021] Example 4, as Figure 4 As shown, the difference between the present invention's water-saving toilet with a float ball automatically closing the lower drain outlet and the above-mentioned embodiment 3 is that the inner end of the upper flush drain wall 12 is hingedly provided with a naturally drooping downwardly extending float ball baffle 5. The naturally drooping downwardly extending float ball baffle 5 has an anti-sticking surface and a specific gravity greater than that of water.

[0022] Example 5, as Figure 5 As shown, the difference between the water-saving toilet with a float that automatically closes the lower drain outlet of the present invention and the above-mentioned embodiments three and four is that at least the lower section of the downwardly extending float baffle 5 is an oblique downward convex arc with the concave surface facing upward toward the drain wall base.

[0023] Example 6: Figure 6 As shown, the present invention's water-saving toilet with a float that automatically closes the lower drain port differs from the aforementioned fifth embodiment in that the toilet 1 is a seated toilet. The seated toilet is provided with a flush hole arranged in a circular pattern within the top. A water inlet 9 is provided at the rear of the circular flush channel, connecting to a flushing pipe or flush tank. This squat toilet is provided with a circular flush channel at the upper end of its elongated collecting hopper 10, which leads to the flush hole.

[0024] In short, the water-saving toilet with a float that automatically closes the lower drain outlet of the utility model has the advantages of no flushing resistance and water consumption caused by a water trap, and the float is not easily contaminated during flushing, so only a small amount of water is needed for flushing and the float is used to isolate odors. It has high flushing efficiency, good odor isolation, and greatly saves water, and is particularly suitable for rural toilet reforms.
