Description

Technical Field

[0001] This invention relates to the field of sanitary facilities technology, and in particular to an ecological toilet and method with the function of degrading feces and concentrating urine. Background Technology

[0002] Currently, public and household toilets are predominantly flush toilets, which use large amounts of clean water to flush human waste into the sewer system, which is then transported to sewage treatment plants via urban sewage networks. This model has several drawbacks: firstly, each flush consumes 3-6 liters or even more of clean water, and this proportion is even higher in water-scarce areas, leading to a serious waste of precious water resources; secondly, feces are rich in essential plant nutrients such as nitrogen, phosphorus, and potassium, which are diluted with sewage after flushing, increasing the burden on sewage treatment and causing a massive loss of resources that could be used as high-quality organic fertilizer, violating the circular economy principles of "reduction, resource recovery, and harmlessness." With the increasing global water shortage and the growing demand for the resource utilization of organic waste, the wasteful use of water and pollution caused by traditional flush toilets urgently needs to be addressed.

[0003] To address the aforementioned shortcomings, "waterless ecological toilets" have become a research hotspot in recent years. Among them, "urine and feces separation toilets" have been gradually applied in scenic areas and rural areas because they can achieve preliminary separation of urine and feces through physical structures (such as baffles and diversion channels), reducing flushing water consumption. For example, some existing technologies disclose squat toilets with inclined toilet bowls and partitions, or sit-down toilets with independent collection chambers under the seat ring, which can direct urine into a urine storage tank (for agricultural irrigation), while feces are temporarily stored in a sealed compartment. However, these separation toilets mostly remain at the "physical separation" stage and fail to further solve the problem of resource utilization of feces and urine: the feces temporarily stored in existing technologies have a high water content and strong odor, requiring frequent transportation to centralized treatment facilities. If transportation is not timely, it can easily cause secondary pollution, and the transportation process also increases transportation costs and environmental burden, with high transportation costs; existing technologies for separating urine mostly use direct discharge, lacking efficient concentration technology, and cannot retain bioactive substances such as organic urea and urokinase in urine, resulting in the waste of high-value-added resources.

[0004] More importantly, designs that directly introduce separated feces into biological septic systems for in-situ / proximal degradation are extremely rare in existing technologies. While biological septic systems (such as aerobic composting and anaerobic fermentation devices) can convert feces into stable organic fertilizer through microbial action, the synergistic problem of "continuous feeding - high-temperature / constant-temperature degradation - odor control" still exists. Currently, although some small-scale septic tanks can handle mixed feces, they cannot adapt to the "dry / semi-dry feces" characteristics (low moisture content, no urine dilution) of separate toilets, and lack a systematic integrated design for biodegradable feces that matches the toilet's separation function, making it difficult to achieve a closed-loop function of "degradation from the source" in sit-down / squat-down toilets.

[0005] Therefore, developing an ecological toilet system that can achieve water conservation and emission reduction through physical separation, as well as in-situ biodegradation of the separated feces and efficient concentration and resource utilization of urine has become a technical problem that the industry urgently needs to solve.

System self-test and initialization: After the controller is powered on, it will automatically perform the following tests: a. Check the temperature of the biological septic tank through the temperature sensor. If it is lower than 15℃, start the heating module to raise the temperature; b. Test the linkage response of each power-requiring component and the angle sensor; S02. Toilet access activation: When the user manually lifts the lid, the angle sensor on the lid's pivot triggers a signal to the controller; the controller starts motor A to rotate forward, which drives the sealing plate to move backward via the transmission belt, exposing the fecal chamber; the ultraviolet light strip automatically turns off, but remains in standby mode. S03. Toileting and Automatic Cleaning: When the user sits down to use the toilet, feces fall into the feces chamber, urine flows into the S-shaped pipe through the urination chamber, and feces are discharged through the feces chamber and the feces outlet at its lower end. After using the toilet, the user closes the lid, triggering the following actions: a. Sealing plate reset: Motor A reverses, pulling the sealing plate forward via the transmission belt to close the opening of the feces chamber; b. Spraying diluted biological septic tank agent: The controller starts the water pump, drawing diluted biological septic tank agent from the storage tank and spraying it into the feces chamber through the spray nozzle; c. Flushing and cleaning: The pressure flusher starts, spraying water onto the inner wall of the urination chamber. S04. Stool degradation and urine concentration: A. Fecal Degradation: ①. Preliminary Decomposition: Feces falling into the biological septic tank through the fecal outlet are mixed with biological septic agent; microorganisms decompose organic matter, breaking down the feces into fecal residue, fecal scum, and suspension; during this process, motor B remains running, driving the vertical shaft to rotate, which in turn drives the lower scraper to rotate continuously, improving the uniformity of mixing between feces and microorganisms; ②. Deep Decomposition: The suspension flows into the biological enhancement tank through the inclined tube, where it is further decomposed in a constant temperature and sealed environment; after 15-20 days of deep degradation, it is converted into liquid organic fertilizer and discharged through the sewage pipe; urine is transported to the urine treatment center for concentration into liquid nitrogen fertilizer, or for extraction of phosphorus and potassium fertilizer, or for concentration according to the following process; B. Urine Concentration: ①. Establishing Negative Pressure: Urine enters the inner cavity of the concentration tank through the S-shaped tube and the replenishment device; the negative pressure generated by the vacuum pump is transmitted to the upper end of the inner cavity of the concentration tank through the negative pressure suction port, the inner cavity of the condenser, the steam inlet, the connecting pipe, and the suction head, adjusting the vacuum degree of the inner cavity of the concentration tank to 0.07-0.1 MPa; ②. Urine Circulation: Motor X starts, driving the propeller to rotate, causing the urine to circulate along the path of "inner cavity of the central ring → upper port of the central ring → inner cavity of the concentration tank → annular interlayer → lower port of the central ring", with a urine flow rate of 1.0-2.5 m / s; ③. Heating Start: The heating material layer inside the central ring starts heating, and the heat is conducted to the inner and outer stainless steel layers of the central ring respectively. When the urine flows through the inner and outer stainless steel layers of the central ring through the above circulation path, The heat is absorbed from the inner and outer stainless steel layers of the central ring for uniform heating; ④. Condensation circulation: The water vapor evaporated by the heated urine enters the lower end of the inner cavity of the condenser and diffuses upward; at the same time, the relatively low-temperature cooling water in the cooling tank enters the upper end of the inner cavity of the condenser and sprays downward; after the upward steam and the downward cooling water come into countercurrent contact, the steam condenses to form condensate, which drips to the lower end of the inner cavity of the condenser; at the same time, the water pump X draws the condensate from the lower end of the inner cavity of the condenser and transports it to the cooling tank, where it is cooled to form cooling water, and the excess cooling water is discharged through the overflow port; ⑤. Concentration and discharge: When the urine in the concentration tank reaches a urea concentration ≥30%, the concentration tank stops concentrating, and at this time the drain port is opened to discharge the concentrated urine. The discharged concentrated urine fully retains the biological activity of the organic matter in the urine.

[0017] The technical solution of this invention is: a method for degrading feces and concentrating urine after using the toilet, based on the above-mentioned ecological toilet with feces degradation and urine concentration functions; the steps are as follows: S01. System self-test and initialization: After the controller is powered on, it will automatically perform the following tests: a. Check the temperature of the biological septic tank through the temperature sensor. If it is lower than 15℃, start the heating module to raise the temperature; b. Test the linkage response of each power-requiring component and pressure sensor; S02. Toilet access activation: When the user presses the pedal, the pressure sensor detects the signal and transmits it to the controller; the controller starts motor A to rotate forward, which drives the sealing plate to move backward through the transmission belt, exposing the fecal chamber; S03. Toileting and Automatic Cleaning: When the user squats to use the toilet, feces are discharged downwards through the feces outlet at the bottom of the feces chamber, and urine flows into the S-shaped pipe through the baffle at the bottom of the urination chamber. After using the toilet, the user leaves the pedal, triggering the following actions: a. Sealing Plate Reset: Motor A reverses, and the transmission belt pulls the sealing plate forward, closing the opening of the feces chamber. After the sealing plate closes, the pressure sensor status is reset, waiting for the next trigger; b. Spraying Diluted Biological Septic Agent: The controller starts the water pump, draws diluted biological septic agent from the storage tank, and sprays the diluted biological septic agent into the feces chamber through the spray nozzle; c. Flushing Cleaning: The pressure flusher starts, spraying water onto the inner wall of the urination chamber. S04. Stool degradation and urine concentration: A. Fecal Degradation: ①. Preliminary Decomposition: Feces fall into the biological septic tank through the feces outlet and mix with the biological septic agent; microorganisms decompose organic matter, breaking down the feces into fecal residue, fecal scum, and suspension; during this process, motor B remains running, driving the vertical shaft to rotate, which in turn drives the lower scraper to rotate continuously, improving the uniformity of mixing between feces and microorganisms; ②. Deep Decomposition: The suspension flows into the biological enhancement tank through the inclined tube, where it is further decomposed in a constant temperature and sealed environment; after 15-20 days of deep degradation, it is converted into liquid organic fertilizer and discharged through the sewage pipe; urine is transported to the urine treatment center for concentration into liquid nitrogen fertilizer, or for extraction of phosphorus and potassium fertilizer, or for concentration according to the following process; B. Urine Concentration: ①. Establishing Negative Pressure: Urine enters the concentration tank cavity through the S-shaped tube and the replenishment device; then the vacuum pump starts, and negative pressure is transferred to the upper end of the concentration tank cavity through the negative pressure suction port, the condenser cavity, the steam inlet, the connecting pipe, and the suction head, adjusting the vacuum degree of the concentration tank cavity to 0.07-0.1 MPa; ②. Urine Circulation: Motor X starts, driving the propeller to rotate, causing the urine to circulate along the path of "central ring cavity → upper port of central ring → concentration tank cavity → annular interlayer → lower port of central ring", with a urine flow rate of 1.0-2.5 m / s; ③. Heating Start: The heating material layer inside the central ring starts heating, and the heat is conducted to the inner and outer stainless steel layers of the central ring respectively. When the urine flows through the inner and outer stainless steel layers of the central ring through the above circulation path... ④. Condensation circulation: The water vapor from the heated urine enters the lower end of the condenser's inner cavity and diffuses upwards; at the same time, the relatively low-temperature cooling water in the cooling tank enters the upper end of the condenser's inner cavity and sprays downwards; after the upward steam and the downward cooling water come into countercurrent contact, the steam condenses to form condensate, which drips to the lower end of the condenser's inner cavity; at the same time, the water pump X draws the condensate from the lower end of the condenser's inner cavity and transports it to the cooling tank, where it is cooled to form cooling water, and excess cooling water is discharged through the overflow port; ⑤. Concentration and discharge: When the urine in the concentration tank reaches a urea concentration ≥30%, the concentration tank stops concentrating, and at this time the drain port is opened to discharge the concentrated urine. The discharged concentrated urine fully retains the biological activity of the organic matter in the urine.

[0018] Compared with the prior art, the present invention has the following advantages: 1. Highly efficient and water-saving, breaking through the limitations of traditional water toilets: Adopting a physical separation design for urine and feces, the urine chamber only requires 0.1L of pressurized water to flush after being filtered through a screen, resulting in significant water-saving efficiency; the separated feces are biodegraded and can be rendered harmless without water flushing, eliminating dependence on water resources, and is especially suitable for arid and water-scarce areas.

[0019] 2. In-situ degradation for closed-loop resource utilization: The biological septic system (biological septic tank + biological enhancement tank) uses microbial degradation technology to convert dry feces into stable liquid organic fertilizer, which can be directly used for agricultural irrigation or to extract nitrogen, phosphorus and potassium elements. After preliminary decomposition, the feces are decomposed into a suspension (the bottom scraping function of the agitator component prevents fecal sludge from settling and scaling, promotes full integration of feces and accelerates degradation). After further deep decomposition, the suspension is output as a resource and can be made into organic liquid fertilizer, feed additives, or extracted industrial raw materials (such as amino acids for the feed industry), realizing "turning waste into treasure".

[0020] 3. Intelligent linkage, fully automated operation: Dual-chamber toilet linkage control: The seated toilet triggers an angle sensor via the lid opening action, while the squatting toilet triggers a pressure sensor via the pedal, thus linking the opening and closing of the sealing plate; Precise spraying and flushing: Automatically matches the dosage of biological septic agent (100-300ml) and the amount of urine flushed (0.1L) according to the toilet type (seat / squat), avoiding resource waste; Ultraviolet sterilization: The seated toilet lid has a built-in ultraviolet light strip that automatically irradiates the seat for 30 minutes to sterilize after each closing; Agitation component and degradation process linkage: When the temperature sensor detects that the temperature is below the threshold, motor B is automatically started to accelerate material mixing; Heating device and degradation process linkage: When the temperature sensor detects that the temperature is below the threshold, the heating device is automatically started to increase the temperature, ensuring that the temperature of the biological septic tank is no lower than 15℃, thereby effectively guaranteeing the normal reproduction and working temperature of biological bacteria at 15-40℃, suitable for cold regions.

[0021] 4. Compact structure, adaptable to diverse scenarios: Two options: the toilet-style model integrates a seat and flip-top, saving space and conforming to urban restroom layouts; the squat toilet-style model features a floor-mounted footrest design, adapting to high-volume public health needs. Modular integration: The biological septic tank mechanism is directly connected to the toilet body, eliminating the need for complex underground pipe networks and making installation and maintenance convenient.

[0022] 5. High-efficiency urine concentration technology: This method employs negative pressure low-temperature evaporation (vacuum degree 0.07-0.1Mpa / 35-59℃) combined with forced circulation by a centrifugal propeller, enabling rapid evaporation and concentration of urine under negative pressure. Compared to traditional atmospheric pressure distillation or high-temperature evaporation, energy consumption is significantly reduced (only maintaining negative pressure and low-temperature heating is required), effectively preventing the decomposition of heat-sensitive substances such as urea. The circulation flow rate of 1.0-2.5m / s ensures uniform heating of the urine, thus improving concentration efficiency.

[0023] 6. Significant ecological benefits, with a significant reduction in odor: It does not produce flammable and explosive gases with foul odors such as biogas, nor does it produce any toxic or harmful substances, eliminating the hidden danger of "biogas explosion" in sewers, with no secondary risks, and avoiding problems such as pipe damage and facility corrosion caused by physical cleaning and chemical cleaning agents; the biological septic system (biological septic tank + biological enhancement tank) uses biodegradation technology to decompose feces into a variety of odorless and harmless substances, reducing odor by 90%, and the odor of toilet exhaust is lower than the minimum olfactory concentration for humans, thus significantly reducing harmful organisms such as mosquitoes, flies, cockroaches, and rats.

Both the defecation chamber 11 and the urination chamber 12 are open at the top and have a flared shape that is wider at the top and narrower at the bottom. The lower ends of the defecation chamber 11 and the urination chamber 12 are respectively provided with a defecation outlet 111 and a urine outlet.

The reciprocating motion drive assembly is arranged adjacent to the defecation chamber 11 and is located on the side of the defecation chamber 11 opposite to the urination chamber 12 (i.e., the urination chamber 12 and the reciprocating motion drive assembly are located on both sides of the defecation chamber 11). The sealing plate 22 is fixedly connected to the front end of the connecting plate 23. The connecting plate 23 is associated with the reciprocating motion drive mechanism at the rear end and is driven by the reciprocating motion drive mechanism to make reciprocating linear movements, thereby causing the sealing plate 22 to close or open the upper opening of the defecation chamber 11.

[0030] The septic tank spraying mechanism includes a spray head 31, a storage tank 32, a water pump 33, and a hose 34. The spray head 31 is embedded in the lower surface of the sealing plate 22 and is used to spray diluted septic tank solution into the fecal cavity 11 (when the sealing plate 22 closes the upper opening of the fecal cavity 11, the spray head 31 is located at the center of the upper end of the fecal cavity 11). The storage tank 32 has an internal cavity for storing the diluted septic tank solution. The water pump 33 is located at the bottom of the inner cavity of the storage tank 32 (submersible pump) or outside the storage tank 32 (suction type). The hose 34 connects the water pump 33 and the spray head 31.

[0031] The biological septic tank mechanism is connected to the lower end of the dual-chamber toilet 1, and includes a biological septic tank 41 and a biological enhancement tank 42 arranged sequentially from the inside to the outside (e.g., Figure 5As shown in the diagram, this forms a preliminary decomposition chamber 411 (i.e., the inner cavity of the biological septic tank 41) located in the inner layer and a deep decomposition chamber 421 (i.e., the annular cavity between the biological septic tank 41 and the biological enhancement tank 42) located in the outer layer.

The installation port 431 is located directly below the feces outlet 111 and is used to receive feces falling from the feces outlet 111 (a connecting pipe can be provided between the feces outlet 111 and the installation port 431). The primary decomposition chamber 411 and the deep decomposition chamber 421 are connected by a flow guiding device, thereby introducing the suspension in the primary decomposition chamber 411 ("suspension" is the intermediate product after the initial decomposition in the biological septic tank, referring to a liquid mixture containing fine suspended particles, that is, the intermediate layer between fecal sludge (sinking) and fecal scum (floating)) into the deep decomposition chamber 421; the deep decomposition chamber 421 is connected to the sewage pipe 422.

[0032] The urine concentration mechanism's replenishment device 511 is connected to the S-shaped tube 122 of the urination chamber 12. It is used to receive the urine discharged from the urination chamber 12 and heat it to 35-59°C under a vacuum of 0.07-0.1 MPa to achieve low-temperature (35-59°C) evaporation and concentration into concentrated urine that retains organic urea and bioactive substances.

The propeller 532 is fixedly mounted on the motor X531 shaft and located within the inner cavity of the central ring 52. After the agitator starts, the driving liquid flows in a cyclical path: "inner cavity of central ring 52 - upper port of central ring 52 - inner cavity of concentration tank 51 - annular jacket 515 - lower port of central ring 52 - inner cavity of central ring 52," ensuring that all the liquid within the concentration tank is fully heated through the central ring 52.

[0034] In this embodiment 1, the dual-chamber toilet 1 is a toilet-type structure. In this structure, the dual-chamber toilet 1 is integrally molded, with the defecation chamber 11 located in the middle and the urination chamber 12 located at the front end. The upper edges of the defecation chamber 11 and the urination chamber 12 at their connection point are at the same height. A transmission element box 13 is provided at the rear end of the dual-chamber toilet 1. The transmission element box 13 is connected to the rear side of the upper edge of the defecation chamber 11 through a strip-shaped opening, through which a sealing plate 22 passes. At the upper open ends of the defecation chamber 11 and the urination chamber 12, the dual-chamber toilet 1 has a seat cushion 14 and a flip cover 15 coaxially rotatably connected by a rotating shaft, with the seat cushion located inside the flip cover 15.

[0035] Correspondingly, the liquid storage tank 32 is connected to the lower end of the transmission element box 13, and the reciprocating motion drive assembly is located inside the transmission element box 13.

[0036] Correspondingly, an ultraviolet light strip is embedded in the inner surface of the flip cover 15 at the position corresponding to the seat cushion 14. When the flip cover 15 is closed, the luminous area of ​​all the ultraviolet light strips completely covers the upper surface of the seat cushion 14.

[0037] Correspondingly, the opening and closing mechanism of the defecation chamber also includes a controller and an angle sensor mounted on the rotating shaft of the flip cover 15. The angle sensor and the motor A214 are respectively connected to the controller in communication.

[0038] More specifically, the dual-chamber toilet 1 has an electrical box 16 at the upper end of the transmission component box 13, which is used to house the controller and power supply.

[0039] More specifically, the lower part of the bio-enhancing tank 42 is provided with a support leg 423, which separates the space required for the installation and maintenance of the motor B49.

[0040] More specifically, a pressure gauge 517 is provided on the top of the concentration tank 51, and a urea concentration measuring module 518 and a temperature measuring module 519 are provided on the side wall of the concentration tank 51.

[0041] More specifically, the reciprocating motion drive assembly includes a driving roller 211, a driven roller 212, a drive track 213, and a motor A214 (e.g., Figure 1 , 2(As shown). The driving roller 211 is horizontally rotatably mounted in the transmission element box 13 at both ends via bearings and bearing seats, and is relatively close to the rear end of the dual-chamber toilet 1. The driven roller is horizontally rotatably mounted in the transmission element box 13 at both ends via bearings and bearing seats, and is relatively close to the front end of the dual-chamber toilet 1. The transmission track 213 is tensioned and wound between the driving roller 211 and the driven roller 212, and the upper surface of the transmission track 213 is fixedly connected to the rear end of the connecting plate. The motor A214 is fixedly mounted in the transmission element box 13. The shaft of the motor A214 is connected to one end of the driving roller 211. The motor A214 outputs rotational power to drive the transmission track 213 to rotate alternately clockwise and counterclockwise, which in turn drives the sealing plate 22 to move reciprocally in a linear motion through the connecting plate 23.

[0042] More specifically, the flow guiding device includes inclined tube 44 (such as...) Figure 5 (As shown). The inclined tube 44 is inclined at an angle of 30-60° relative to the horizontal plane. Its upper end passes through the side wall of the biological septic tank 41 and enters the deep decomposition chamber 421. Its lower end is provided with a mesh barrier 441 and is located in the preliminary decomposition chamber 411. The mesh on the barrier 441 only allows the suspension obtained by the preliminary decomposition of feces to pass through.

[0043] More specifically, the sealing plate 22 is arranged at an angle. The end of the sealing plate 22 connected to the connecting plate 23 is the high end, and the end of the sealing plate 22 near the urinary cavity 12 is the low end. The low end of the sealing plate 22 extends beyond the upper edge of the junction of the defecation cavity 11 and the urinary cavity 12. Urine splashed on the sealing plate 22 can enter the urinary cavity along the slope of the sealing plate 22 to avoid urine stagnation between the sealing plate 22 and the defecation cavity 11.

[0044] More specifically, the biological septic tank also includes a heating device. The heating device includes a temperature sensor 351 installed in the primary decomposition chamber 411, a heating module 352 embedded in the lower bottom of the primary decomposition chamber 411 and the deep decomposition chamber 421, and a layer of insulating material (such as...) covering the exterior of the biological enhancement tank 42 (including the exterior of the side walls and the lower bottom wall). Figure 5 (As shown).

[0045] More specifically, biological septic tank systems also include agitator components (such as...) Figure 1 , 5(As shown). The agitation assembly includes a vertical shaft 45, an upper horizontal bar 461, a lower horizontal bar 462, an upper agitator 471, a lower scraper 472, a manure sliding plate 48, and a motor B49. The vertical shaft 45 is vertically arranged and rotatably mounted in the primary decomposition chamber 411 via bearings and bearing seats 451. The lower end of the vertical shaft 45 passes through the bottom plate of the primary decomposition chamber 411 and is located at the lower outer end of the bio-enhancing tank 42. The upper horizontal bar 461 and the lower horizontal bar 462 are respectively horizontally fixedly mounted on the vertical shaft 45 and are both located in the primary decomposition chamber 411, with the upper horizontal bar 461 located above the lower horizontal bar 462. Multiple upper agitator plates 471 are fixedly connected at intervals to the lower end of the upper horizontal bar 461, and they are used together to agitate the manure and its decomposition products in the primary decomposition chamber 411. When the vertical shaft 45 rotates, the annular area swept by all the upper agitator plates 471 together covers the cross-section of the primary decomposition chamber 411. Multiple lower scrapers 472 are fixedly connected at intervals to the lower end of the lower crossbar 462. They work together to scrape the sediment at the bottom of the primary decomposition chamber 411. When the vertical shaft 45 rotates, the annular area swept by all the lower scrapers 472 collectively covers the cross-section of the primary decomposition chamber 411. A manure sliding plate 48 is detachably fixedly connected to the upper end of the vertical shaft 45, arranged at an angle, and located at the upper end of the primary decomposition chamber 411. It is used to buffer and guide the manure falling above it into the primary decomposition chamber 411. A motor B49 is fixedly installed on the lower part of the outside of the bio-enhancing tank 42. Its shaft extends vertically upward and is connected to the lower end of the vertical shaft 45 through a coupling, thereby driving the vertical shaft 45 to rotate. The motor B49 drives the vertical shaft 45 to rotate, which in turn drives the upper stirring plate 471 and the lower scrapers 472 to rotate, promoting the fusion of manure and microorganisms and accelerating the biodegradation of manure.

[0046] More specifically, a sleeve wrench (quadrilateral / hexagonal) is provided at the end of the vertical shaft at the upper end of the manure sliding plate 48. The top of the wrench is spherical to prevent manure from accumulating. Additionally, a sleeve wrench that matches the sleeve wrench is also provided. When the device needs to be used after a long period of inactivity, or when the motor fails to start, the biological septic agent must be added again. After the settled and dried material has been fully soaked and softened (if the inactivity period is too long, sufficient soaking time must be ensured, otherwise the lower scraper may be damaged), the sleeve wrench can be placed on the sleeve wrench, and the sleeve wrench can be manually rotated to scrape up the softened manure scum and residue through the lower scraper 472 for biodegradation.

[0047] More specifically, the walls of the fecal cavity 11, the walls of the urinary cavity 12, and the surface of the sealing plate 22 are all provided with a non-stick coating.

[0048] More specifically, the urine outlet of the urinary cavity 12 is provided with a mesh barrier, and the lower end of the urine outlet of the urinary cavity 12 is connected to the S-shaped tube 122.

[0049] More specifically, the urine concentration mechanism also includes an air extraction head 59. The air extraction head 59 is a hollow hemispherical shape, formed by a spherical wall 591 and a circular flat plate 592 located at the lower end of the spherical wall 591. An arc-shaped partition 595 is provided in the hemispherical cavity formed by the spherical wall 591 and the circular flat plate 592, which divides the hemispherical cavity into an air inlet sub-cavity at the upper end and an anti-foaming sub-cavity at the lower end. The air inlet sub-cavity and the anti-foaming sub-cavity are not connected to each other. An interface 593 connecting to the anti-foaming sub-cavity is provided at the upper end of the spherical wall 591. The spherical wall 591 is provided with multiple air holes 594 connecting to the air inlet sub-cavities. The spherical wall 591 is also provided with a drain hole 596 connecting to the air inlet sub-cavities and smoothly connected to the arc-shaped partition 595. The suction head 59 is detachably connected to one end of the connecting pipe 56 located inside the concentrator 51 via the interface 593, and the circular plate 592 is arranged facing the lower end of the concentrator 51. Based on this structure, the circular plate 592 and the arc-shaped baffle 595 form a physical barrier to prevent the foam on the upper layer of urine from rising into the air inlet chamber, thereby ensuring the smooth flow of negative pressure suction. In addition, the arc-shaped guide structure of the spherical wall 591 allows the foamed urine to slide back into the concentrator 51. Furthermore, if a small amount of urine foam still enters the air inlet chamber through the air hole 594, the urine will slide down to the upper surface of the arc-shaped baffle 595, flow along the arc of the arc-shaped baffle 595 to the edge, until it is discharged outside the air inlet chamber through the drain hole 596, and finally slide back into the concentrator 51.

[0050] More specifically, both the preliminary decomposition cavity and the deep decomposition cavity are cylindrical. The cross-section of the preliminary decomposition cavity is any one of the following: circular, elliptical, convex polygon, annular, fan-shaped, or fan-annular. The cross-section of the deep decomposition cavity is any one of the following: circular, elliptical, convex polygon, fan-shaped, or fan-annular. The positional relationship between the preliminary decomposition cavity and the deep decomposition cavity is any one of the following: connected by outer walls (e.g., the preliminary decomposition cavity and the deep decomposition cavity are separated into two semi-cylinders in a cylindrical cavity), nested inside and outside, or relatively independent.

[0051] Example 2: like Figure 9 As shown, in Embodiment 2, the dual-chamber toilet 1 is a squat toilet structure. In this structure, the dual-chamber toilet 1 is integrally molded, with the defecation chamber 11 located in the middle and the urination chamber 12 located at the front end. The upper edges of the defecation chamber 11 and the urination chamber 12 are at the same height at their connection point. A transmission element box 13 is provided at the rear end of the dual-chamber toilet 1. The transmission element box 13 is connected to the rear side of the upper edge of the defecation chamber 11 through a strip-shaped opening, through which a sealing plate 22 passes.

[0052] Correspondingly, the liquid storage tank 32 is connected to the upper end of the transmission element box 13, and the reciprocating motion drive assembly is located inside the transmission element box 13.

[0053] Correspondingly, the toilet chamber opening and closing mechanism also includes a controller and pedals arranged on the ground on both sides of the dual-chamber toilet 1 in the front-to-back direction, with pressure sensors embedded in the pedals. The pressure sensors and motor A214 are respectively connected to the controller in communication.

[0054] Briefly describe the working principle of this invention: The aforementioned "ecological toilet with urine and feces separation and degradation function" achieves fully automated processing of "urine and feces separation → instant disinfection → in-situ degradation → resource transportation" through three core modules: physical separation of dual-chamber toilets, intelligent linkage control, and closed-loop treatment of biodegradation.

[0055] I. Physical Separation Logic of Dual-Cavity Toilets In Example 1, when the user opens the flip cover 15, the angle sensor detects a signal, the controller starts the motor A214, drives the sealing plate 22 to move backward, exposing the fecal cavity 11, so that defecation can be performed; the discharged urine flows into the S-shaped tube 122 through the urinary cavity 12.

[0056] In Example 2, when the user steps on the pedal, the pressure sensor triggers the motor A214 to start, driving the sealed plate 22 to move backward, exposing the fecal cavity 11, thus allowing defecation; the discharged urine flows into the S-shaped tube 122 through the urinary cavity 12.

[0057] II. Intelligent Linkage Control Logic In Example 1: Toilet access opening: Flip cover 15 opens → sealing plate 22 moves back → exposing fecal cavity 11 (user uses toilet); Toilet access closing: Flip cover 15 closes → sealing plate 22 moves forward, closing fecal cavity 11 → triggering spray head 31 to spray biological septic agent (100-300ml) → starting pressure flusher 121 to flush urinal cavity 12 with water (0.1L pressure water).

[0058] In Example 2: Toilet access opening: the pedal is pressed → the sealing plate 22 moves backward → the fecal cavity 11 is exposed (user uses the toilet); Toilet access closing: the pedal is reset → the sealing plate 22 moves forward, closing the fecal cavity 11 → the spray head 31 is triggered to spray biological septic agent (100-300ml) → the pressure flusher 121 is activated to flush the urinal cavity 12 with water (0.1L pressure water).

[0059] III. Closed-loop biological septic tank treatment 3.1 Structural Composition: Biological septic tank (preliminary decomposition chamber 411): The inner cylindrical chamber is designed with a volume of "0.5L / person / day × 15 days × number of people × fluctuation rate (100%~150%)", and is filled with biological septic agent (Bacillus, Lactic acid bacteria, etc., with an effective live bacteria count ≥2 billion / ml) at a pre-added amount of 30%-50% of the biological septic tank volume. Biological enhancement tank 42 (deep decomposition chamber 421): The outer annular deep decomposition chamber 421 has a volume twice that of the inner cylindrical preliminary decomposition chamber 411, and the two chambers are connected by a 30-60° inclined tube 44. Heating device: Temperature sensor 351 monitors the temperature inside the preliminary decomposition chamber; heating module 352 (carbon fiber heating element) and insulation layer (polyurethane material) work together to maintain the optimal bacterial activity temperature of 15-40℃.

[0060] 3.2 Degradation process: Preliminary decomposition: Feces fall into the biological septic tank 41 through the feces outlet and mix with the biological septic agent; microorganisms decompose organic matter, breaking down the feces into fecal sludge (sinking), fecal scum (floating), and suspension (intermediate layer); Deep decomposition: The suspension flows into the biological enhancement tank through the screen at the lower end of the inclined tube 44 (filtering fecal scum / large particles); under constant temperature and closed environment, it is further decomposed into stable liquid organic fertilizer.

[0061] 3.3 Resource-based output: The suspension after deep decomposition in the biological enhancement tank 42 (deep decomposition chamber 421) is transported to the collection center through the sewage pipe 422 for centralized treatment; after being buffered by the S-shaped pipe 122, the urine enters the urine concentration mechanism through the pipeline, where it is evaporated and concentrated into concentrated urine that retains organic urea and bioactive substances.

[0062] Briefly describe the usage process of Example 1: Before a user uses the toilet, the status of each component is as follows: the sealing plate 22 is in the closed state, sealing the upper opening of the fecal chamber 11; the S-shaped tube 122 has a water seal to prevent odors from backflowing.

[0063] The user's toilet usage process is as follows: S01. System Self-Test and Initialization: After the controller is powered on, it automatically performs the following tests: a. Checks the temperature of the biological septic tank (via temperature sensor 351). If it is below 15℃, it starts the heating module 352 to raise the temperature; b. Tests the linkage response of each power-requiring component and the angle sensor.

[0064] S02. Toilet access enabled: When the user manually lifts the flip cover 15, the angle sensor located on the rotating shaft of the flip cover 15 triggers a signal to the controller; the controller starts the motor A214 to rotate forward, which drives the sealing plate 22 to move backward through the transmission track 213, exposing the fecal chamber 11; the ultraviolet light strip embedded in the seat cushion 14 automatically turns off (to avoid irradiating the human body), but remains in standby mode.

[0065] S03. Toilet use and automatic cleaning: When a user uses the toilet, urine flows into the S-shaped tube 122 through the lower baffle of the urinal chamber 12, and feces are discharged downwards through the feces outlet 111 at the lower end of the feces chamber 11. After using the toilet, the user closes the flip cover 15, triggering the following actions: a. Sealing plate reset: Motor A214 reverses, and the transmission track 213 pulls the sealing plate 22 forward, closing the opening of the fecal chamber 11; after the sealing plate 22 is closed, the controller records the usage data (such as timestamp) to provide a reference for the biodegradation cycle. b. Spraying diluted biological septic agent: The controller starts the water pump 33 to draw the diluted biological septic agent from the storage tank 32 and deliver it to the spray head 31 through the hose 34, so that the spray head 31 sprays 100-300ml of diluted biological septic agent into the fecal cavity 11. c. Flushing and cleaning: The electric delay switch controls the start of the pressure flush 121, which sprays 0.1L of pressurized water (3-4kPa) into the inner wall of the urinal cavity 12.

[0066] S04. Stool degradation and urine concentration: A. Stool decomposition: ①. Preliminary decomposition (biological septic tank): Feces fall into the biological septic tank through the feces outlet 111 and mix with the biological septic agent; microorganisms (Bacillus, lactic acid bacteria, etc.) decompose organic matter, breaking down the feces into: fecal sludge (sinks to the bottom of the tank and is periodically discharged through the sewage pipe 422), fecal scum (floats to the surface and is intercepted by the inclined pipe 44), and suspension (the middle layer, containing fine particles, which enters the deep decomposition chamber); during this process, the motor B49 remains running, driving the vertical shaft 45 to rotate, which in turn drives all the upper stirring plates 471 and lower scrapers 472 to rotate continuously, improving the uniformity of the mixing of feces and microorganisms.

[0067] ②. Deep Decomposition (Bio-enhanced Tank): The suspension flows into the bio-enhanced tank through inclined tube 44, where it undergoes further decomposition in a constant temperature (15-40℃) and sealed environment. After 15-20 days of deep degradation, it is transformed into stable liquid organic fertilizer, which is then transported to the waste treatment center through sewage pipe 422. The waste products after waste treatment are used to produce organic liquid fertilizer, solid fertilizer, or feed additives. Urine is transported to the urine treatment center for concentration into liquid nitrogen fertilizer, or for the extraction of phosphorus and potassium fertilizer, or for concentration according to the following process.

[0068] B. Concentrated urine: ①. Creating negative pressure: Urine enters the inner cavity of the concentration tank 51 through the S-shaped tube 122 and the replenishment device 511; the negative pressure generated by the vacuum pump 58 is transmitted to the upper end of the inner cavity of the concentration tank 51 through the negative pressure suction port 543, the inner cavity of the condenser 54, the steam inlet 541, the connecting pipe 56, and the suction head 59, adjusting the vacuum degree of the inner cavity of the concentration tank 51 to 0.07-0.1 MPa; ②. Urine circulation: When motor X531 starts, it drives propeller 532 to rotate, causing urine to circulate along the path of "inner cavity of central ring → upper port of central ring → inner cavity of concentration tank → annular jacket → lower port of central ring"; the urine flow rate is 1.0-2.5m / s; ③. Heating starts: The heating material layer inside the central ring starts heating, and the heat is conducted to the inner and outer stainless steel layers of the central ring. When the urine flows through the inner and outer stainless steel layers of the central ring through the above circulation path, it absorbs the heat from the inner and outer stainless steel layers of the central ring and is heated evenly. ④. Condensation Circulation: Water vapor from the heated urine enters the lower end of the condenser tank 54 through the suction head 59, connecting pipe 56, and steam inlet 541, and diffuses upwards; simultaneously, cooling water with a relatively low temperature in the cooling tank 55 enters the upper end of the condenser tank 54 through the cooling water outlet 552, pipe, and cooling water inlet 544, and sprays downwards; after the upward steam and downward cooling water come into countercurrent contact in the middle of the condenser tank 54, the steam condenses to form condensate, which drips to the lower end of the condenser tank 54; at the same time, water pump X57 draws the condensate from the lower end of the condenser tank 54 and transports it to the cooling tank 55, where it is cooled into cooling water. Excess cooling water is discharged through overflow outlet 551 and used as reclaimed water. ⑤. Concentration and discharge: When the urine in the concentration tank 51 reaches a urea concentration of ≥30%, the concentration tank stops concentrating. At this time, the discharge port 516 is opened to discharge the concentrated urine. The discharged concentrated urine fully retains the biological activity of the organic matter in the urine and can be used directly as organic liquid nitrogen fertilizer, or as a raw material for extracting bioactive substances such as urokinase and human chorionic gonadotropin (HCG).

[0069] Briefly describe the usage process of Example 2: When no one is using the toilet, the status of each component is as follows: the sealing plate 22 is in the closed state, sealing the upper opening of the fecal cavity 11; the S-shaped tube 122 has a water seal to prevent odors from backflowing.

[0070] The user's toilet usage process is as follows: S01. System Self-Test and Initialization: After the controller is powered on, it automatically performs the following tests: a. Checks the temperature of the biological septic tank (via temperature sensor 351). If it is below 15℃, it starts the heating module 352 to raise the temperature; b. Tests the linkage response of each power-requiring component (i.e., each actuator) and pressure sensor.

[0071] S02. Toilet access enabled: When the user presses the pedal, the pressure sensor detects the signal and transmits it to the controller; the controller starts the motor A214 to rotate forward, which drives the sealing plate 22 to move backward through the transmission track 213, exposing the fecal chamber 11.

[0072] S03. Toilet use and automatic cleaning: When a user squats to use the toilet, feces are discharged downwards through the feces outlet 111 at the lower end of the feces chamber 11, and urine flows into the S-shaped pipe 122 through the baffle at the lower end of the urination chamber 12. After using the toilet, the user leaves the pedal, triggering the following actions: a. Sealing plate reset: Motor A214 reverses, and the transmission track 213 pulls the sealing plate 22 forward, closing the opening of the fecal chamber 11. After the sealing plate 22 is closed, the controller resets the pressure sensor state and waits for the next trigger. b. Spraying diluted biological septic agent: The controller starts the water pump 33 to draw the diluted biological septic agent from the storage tank 32 and deliver it to the spray head 31 through the hose 34, so that the spray head 31 sprays 100-300ml of diluted biological septic agent into the fecal cavity 11. c. Flushing and cleaning: The electric delay switch controls the start of the pressure flush 121, which sprays 0.1L of pressurized water (3-4kPa) into the inner wall of the urinal cavity 12.

[0073] S04. Stool degradation and urine concentration: A. Stool decomposition: ①. Preliminary decomposition (biological septic tank): Feces fall into the biological septic tank through the feces outlet and mix with the biological septic agent; microorganisms (Bacillus, lactic acid bacteria, etc.) decompose organic matter, breaking down the feces into: fecal sludge (sinking to the bottom of the tank and periodically discharged through the sewage pipe), fecal scum (floating to the surface and intercepted by the inclined tube 44), and suspension (the middle layer, containing fine particles, which enters the deep decomposition chamber); during this process, motor B49 remains running, driving the vertical shaft 45 to rotate, which in turn drives all the upper stirring plates 471 and lower scrapers 472 to rotate continuously, improving the uniformity of mixing of feces and microorganisms.

[0074] ②. Deep Decomposition (Bio-enhanced Tank): The suspension flows into the bio-enhanced tank through inclined tubes, where it undergoes further decomposition in a constant-temperature (15-40℃) and sealed environment. After 15-20 days of deep degradation, it is transformed into stable liquid organic fertilizer, which is then transported to the waste treatment center through a sewage pipe. The waste products after waste treatment are used to produce organic liquid fertilizer, solid fertilizer, or feed additives. Urine is transported to the urine treatment center for concentration into liquid nitrogen fertilizer, or for the extraction of elements such as phosphorus, potassium, magnesium, and selenium, or for concentration using the following process.

[0075] B. Concentrated urine: ①. Establishing negative pressure: After urine is discharged from the S-shaped tube 122, it enters the inner cavity of the concentration tank through the replenishment device 511; then the vacuum pump is started, and the negative pressure is transmitted to the upper end of the inner cavity of the concentration tank 51 through the negative pressure suction port 543, the inner cavity of the condenser 54, the steam inlet 541, the connecting pipe 56, and the suction head 59, adjusting the vacuum degree of the inner cavity of the concentration tank 51 to 0.07-0.1Mpa; ②. Urine circulation: When motor X starts, it drives the propeller to rotate, causing the urine to circulate along the path of "inner cavity of the central ring → upper port of the central ring → inner cavity of the concentration tank → annular jacket → lower port of the central ring"; so that the urine flow rate is 1.0-2.5m / s; ③. Heating starts: The heating material layer inside the central ring starts heating, and the heat is conducted to the inner and outer stainless steel layers of the central ring. When the urine flows through the inner and outer stainless steel layers of the central ring through the above circulation path, it absorbs the heat from the inner and outer stainless steel layers of the central ring and is heated evenly. ④. Condensation Circulation: Water vapor from the heated urine enters the lower end of the condenser tank 54 through the suction head 59, connecting pipe 56, and steam inlet 541, and diffuses upwards; simultaneously, cooling water with a relatively low temperature in the cooling tank 55 enters the upper end of the condenser tank 54 through the cooling water outlet 552, pipe, and cooling water inlet 544, and sprays downwards; after the upward steam and downward cooling water come into countercurrent contact in the middle of the condenser tank 54, the steam condenses to form condensate, which drips to the lower end of the condenser tank 54; at the same time, water pump X57 draws the condensate from the lower end of the condenser tank and transports it to the cooling tank 55, where it is cooled to form cooling water, and excess cooling water is discharged through overflow outlet 551; ⑤. Concentration and discharge: When the urine in the concentration tank reaches a urea concentration of ≥30%, the concentration tank stops concentrating. At this time, the discharge port 516 is opened to discharge the concentrated urine. The discharged concentrated urine fully retains the biological activity of the organic matter in the urine and can be used directly as organic liquid nitrogen fertilizer or as a raw material for extracting bioactive substances such as urokinase.
