Description

Technical Field

[0001] The invention relates to the technical field of sanitary ware, in particular to a flush-free single-layer ceramic urinal and a urine resource recovery system thereof. Background Art

[0002] At present, the drainage and sewage interface structure holes of existing water-free urinal devices and all sanitary ware are designed to be located in the center, which makes the interface and the corresponding drainage cylinder larger in volume and increases the product cost. In addition, all sanitary ware, as long as the material is ceramic, is sintered into double-layer ceramics regardless of whether it is stressed or not, which has high manufacturing cost, complex process and heavy installation; secondly, the existing water-free urinals are not equipped with physical, chemical and biological delivery devices, and cannot systematically realize the collection of urine resources after treatment from the source; finally, the current water-free urinal assembly process is complicated, especially the assembly of the drainage interface and the drainage cylinder is time-consuming, labor-intensive and material-consuming. In addition, after long-term use, the anti-odor baffle has poor resilience at the lotus leaf-like opening and closing gap of the thermoplastic elastomer covered, which is easy to produce gaps and cannot play the role of preventing odor.

[0003] Through public patent search, the following comparative documents were found:

[0004] CN103628536B discloses a microbial flora release device for a urinal and a sewer pipe, which is characterized by comprising a water receiving tray, an outer cylinder connected to the sewer pipe, a membrane-sealed sewage backflow prevention device and an inner cylinder, the top of the outer cylinder is connected to the water receiving tray, the inner cylinder is fixedly connected to the inner cavity of the outer cylinder, the upper opening of the inner cylinder is connected to the water receiving tray, the water receiving tray is fixedly connected to the membrane-sealed sewage backflow prevention device, and a flora / urine mixed culture chamber is provided in the inner cylinder cavity. Beneficial effect: the size of the flora / urine mixed culture chamber is set, when urine passes through the flora block, it will take away a certain amount of beneficial bacteria, and the urine containing beneficial bacteria will continue to grow and reproduce in the culture chamber. Each time the urinal is used, the liquid in the culture chamber will not be completely replaced, which provides sufficient time for the generation and reproduction of the flora. The urine flowing into the sewer will take away a large number of beneficial bacteria, which will adhere to the sewer pipe wall after flowing through the pipeline, and can produce enzymes to decompose the urine scale inside the sewer.

[0005] After analysis, it is found that the urinal in the above-mentioned patent has significant differences compared with the present application in terms of the eccentric structure design to reduce the diameter of the discharge tube and the anti-odor structure design. In addition, the urinal in the above-mentioned patent uses bacterial blocks to degrade by urine, which only achieves the function of pipe descaling.

[0036] In addition, in the present invention, preferably, the eccentric drain bowl and the leakage cone tube are fixedly connected by rivets, which adopts mature technical means in the prior art.

[0037] In order to more clearly illustrate the specific implementation mode of the present invention, an embodiment is provided below:

[0038] The present invention discloses a flush-free single-layer ceramic urinal and a urine resource recovery system thereof. The ceramic body of the urinal of the present invention is a single-layer solid structure, and there is no cavity inside it, so that it is easy to process and has low cost. Moreover, no flushing is required, and urine does not hang on the wall and is guided in sequence through the inner arc of the urinal ceramic body, the eccentric discharge bowl and the leakage cone tube. The anti-return odor baffle acts as a one-way valve. The anti-return odor baffle seals the discharge end face of the leakage cone tube under its own gravity to prevent odor from returning upward; then the urine is discharged into the urine resource collection box through the discharge elbow. As the urine in the urine resource collection box increases and reaches the set liquid level, the liquid level meter sends a signal to the controller. The controller controls the physical, chemical and biological delivery device to deliver physical, chemical and biological materials into the ceramic body of the urinal. On the one hand, the overall cleanliness of the urinal is more stable. On the other hand, it can react with urine in a quantitative and proportional manner to preserve the urine from the source and make it a useful resource. Finally, the controller controls the solenoid valve to open to empty the urine in the urine resource collection box. The discharged urine can be collected and recycled as a resource.

[0039] In order to achieve the stability and reliability of water-free urinals, the sealing technology is the key. Because there must be active substances in the body of the water-free urinal and they will grow naturally, which will affect the stability of the seal. Therefore, the most effective method must be used to fundamentally solve the problem in order to achieve a long-term and stable sealing effect.

[0040] For example, in the prior art, the two-film plugging structure is a transparent silicone rubber barrel, one end of which is round and can be fixed to the excretion pipe or floor drain, and the other end is two closed membranes. When liquid flows through, the two membranes open, and when no liquid flows through, the two membranes close to play a plugging role. It is usually believed that it can play the most reliable plugging effect, but because there will be urine residue in the two membranes, the growth of microorganisms in the urine will produce some flocs similar to soft scale in a very short time. After the flocs of soft scale gradually increase, they push up the two membranes to create a gap, and the plugging effect is destroyed. In addition, there is also an umbrella-like leakage structure, which is equivalent to the structure of two membranes in principle and the result of use is the same, and it cannot play a stable and long-term tight sealing function.

[0041] The contact surface between the leakage cone tube and the anti-odor return baffle of the present application is designed to be blade-shaped all around, combined with the pressure balance of our new anti-odor return baffle, and the contact area is only the surrounding line, while the two sealing devices in the prior art both have larger contact surfaces. Therefore, the sealing form of the anti-odor return baffle and the leakage cone tube of the present application, firstly, no residue will remain when urine flows through, and secondly, even if there is floccules produced by the growth of microorganisms in urine, there is only contact on the blade-like edge like a line between the leakage cone tube and the anti-odor return baffle, and there is no condition for it to stay. The line contact technology formed between the leakage cone tube and the anti-odor return baffle and the addition of deformation through holes on the anti-odor return baffle achieves the balance of the overall pressure of the anti-odor return baffle. In particular, when the deformation through holes are deformed, the anti-odor return baffle can be given a certain degree of stability. Figure 5 The clockwise blocking torque shown can effectively block the drainage groove at the bottom of the leakage cone. The design of the drainage groove can provide a larger contact area between the residual urine and the anti-odor baffle when the urine is about to flow out and the anti-odor baffle is about to reset, ensuring that a small amount of urine pushes the anti-odor baffle, preventing a small amount of urine from accumulating inside the leakage cone and generating odor.

[0042] In summary, the flush-free single-layer ceramic urinal and the urine resource recovery system thereof of the present application can fully achieve the effect of long-term stable and tight sealing, and realize the scientific and stable flush-free function of the urinal.

[0043] Finally, all the parts not described in the present invention adopt mature products and mature technical means in the prior art.

[0044] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
