[0070] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0071] The present invention provides a sealing system suitable for ecological toilets, such as Figures 1 to 13 As shown, it includes a first push-pull mechanism, a second push-pull mechanism and a sealing ring 11. The sealing ring 11 preferably adopts a circular tubular structure with a diameter of 15 cm and a height of 10 cm. The top of the sealing ring 11 is connected to the first push-pull mechanism, and the bottom of the sealing ring 11 is connected to the feces storage unit. The second push-pull mechanism is arranged between the feces storage unit and the first push-pull mechanism, and the first push-pull mechanism, the second push-pull mechanism and the sealing ring 11 form a first accommodating space. The first push-pull mechanism and the second push-pull mechanism can be switched between an open state and a closed state. When the first push-pull mechanism is in an open state, the first accommodating space is connected to the outside through the toilet body 2 of the toilet system. When the second push-pull mechanism is in an open state, the first accommodating space is connected to the feces storage unit. When the first push-pull mechanism and the second push-pull mechanism are both in a closed state, the first accommodating space is a closed space.

[0072] Specifically, a urine drainage groove 14 is provided at the front end of the top of the sealing ring 11, and the first push-pull mechanism includes a first driving mechanism and a first receiving plate 9. The first receiving plate 9 is provided at the rear end of the top of the sealing ring 11. When the first driving mechanism drives the first receiving plate 9 to move toward the urine drainage groove 14 to a first position, the first push-pull mechanism is in a closed state. When the first driving mechanism drives the first receiving plate 9 to move away from the urine drainage groove 14 to a second position, the first push-pull mechanism is in an open state.

[0073] Furthermore, the first push-pull mechanism also includes two first guide rails 8 and a first scraper, the first driving mechanism includes a first motor 6 and a first screw rod 7, the two first guide rails 8 are arranged in parallel and are both installed on the carrier 32, the first motor 6 is connected to the first receiving plate 9 through the first screw rod 7 and can drive the first screw rod 7 to drive the first receiving plate 9 to slide with the two first guide rails 8, the first scraper is installed above the first receiving plate 9 and both ends are installed on the carrier 32, the bottom edge of the first scraper is in contact with the first receiving plate 9 and can scrape the top of the first receiving plate 9 when the first receiving plate 9 moves.

[0074] Preferably, the first receiving plate 9 extends toward one end edge of the urinary catheter groove 14 to above the axis of the urinary catheter groove 14 and the first receiving plate 9 is arranged to be tilted downward toward one end of the urinary catheter groove 14 .

[0075] It should be noted that the first receiving plate 9 has a downward tilt angle toward the urinary drainage groove 14, for example, 3°, or another example, 7°. When the user urinates, urine can flow along the tilted first receiving plate 9 into the urinary drainage groove 14, and then flow into the urine storage bucket 18. The urine storage bucket 18 is detachable. When the urine storage bucket 18 is full, it can be disassembled and replaced with a spare urine storage bucket 18, and the full urine storage bucket 18 can be transported away for disposal. The edge of the first receiving plate 9 extends above the center of the urinary drainage groove 14, so the urine naturally flows into the urinary drainage groove 14 along the tilted flow direction. At the same time, the gap between the first receiving plate 9 and the urinary drainage groove 14 can enable the first accommodating space with a micro-negative pressure environment to suck the air inside the toilet body 2, thereby ensuring the freshness of the air.

[0076] Specifically, the second push-pull mechanism includes a second driving mechanism and a second socket plate 10, the bottom of the sealing ring 11 is provided with a mounting slot in the radial direction, and the second socket plate 10 can be moved to the third position in the mounting slot under the drive of the second driving mechanism. At this time, the second push-pull mechanism is in a closed state, and when the second driving mechanism drives the second socket plate 10 away from the mounting slot to move to the fourth position, the second push-pull mechanism is in an open state, the second push-pull mechanism includes two second guide rails 43 and a second scraper, the second driving mechanism includes a second motor 41 and a second screw rod 42, the two second guide rails 43 are installed in parallel on both sides of the carrier 32 and slide with both sides of the second socket plate 10, the second motor 41 is connected to the second socket plate 10 through the second screw rod 42 and can drive the second screw rod 42 to drive the second socket plate 10 to move, the second scraper is installed above the second socket plate 10 and both ends are installed on the sealing ring 11, the bottom edge of the second scraper contacts the second socket plate 10 and can scrape the top of the second socket plate 10 when the second socket plate 10 moves.

[0077] Specifically, in a preferred embodiment, the first receiving plate 9 and the second receiving plate 10 are respectively drawer-shaped structures with three-sided retaining edges, such as Figure 1 As shown, the first scraper and the second scraper adopt a detachable rubber structure and are fixed to the flat steel by bolts.

[0078] In order to match the receiving and sealing system in the present invention, a preferred example is also provided with a bedpan system, a liquid conduction switching system, a ventilation system, a plant filter system, a feces storage system and a control system. The feces storage system includes a feces storage unit and a urine storage unit. The bedpan system is connected to the feces storage unit. The receiving and sealing system is installed on the bedpan system. The ventilation system is connected to the receiving and sealing system. The bedpan system is respectively connected to the plant filter system and the urine storage unit through the liquid conduction switching system. The control system is respectively electrically connected to the bedpan system, the liquid conduction switching system, the receiving and sealing system and the ventilation system. The present invention realizes the four-element separation of feces, urine, flushing water and toilet paper, and feces and urine are separated from the source, without secondary pollution, odorless, good sanitary conditions and strong practicality.

[0079] Specifically, the liquid conduction switching system includes a urinary catheterization groove 14, a liquid conduction tube 15, a first guide tube 16, a second guide tube 23 and a liquid flow direction control valve 30. One end of the liquid conduction tube 15 is connected to the urinary catheterization groove 14, and the other end of the liquid conduction tube 15 is connected to the first guide tube 16 and the second guide tube 23 respectively through the liquid flow direction control valve 30. The liquid flow direction control valve 30 is electrically connected to the control system.

[0080] Specifically, the toilet system includes a water tank 1, a toilet body 2 and a toilet cover 19. The toilet cover 19 is rotatably mounted on the toilet body 2 and a sensing device is mounted on the rotating shaft. When the toilet cover 19 is opened, the touch sensing device and the control system control the exhaust fan 4 to start running. When the toilet cover 19 is closed, the touch sensing device and the control system control the exhaust fan 4 to stop running. The water tank 1 is provided with a water tank inlet channel and a water tank outlet channel and a submersible pump is installed inside. The outlet of the submersible pump is connected to the toilet water outlet on the inner wall 21 of the toilet body through the water tank outlet channel. The water tank 1 is flexibly installed in the toilet body 2. In a preferred example, it is designed as a drawer structure and can be pulled out as needed. The water tank 1 can be connected to the tap water pipe for water replenishment. For example, a liquid level sensor is set in the water tank 1 and connected to the control system signal. The control system selects to control the switch of the valve on the tap water pipe according to the set liquid level value to realize the water replenishment operation of the water tank 1. Water can also be added manually, which can be flexibly selected according to the actual application scenario.

[0081] Furthermore, the toilet water outlet is positioned above the first receiving plate 9 of the receiving sealing system. A first valve and a second valve are respectively provided on the water tank inlet and outlet channels. A control button 12 is provided on the toilet body 2. The control button 12, the first valve, the second valve, the submersible pump, and the sensing device are electrically connected to a control system. In a preferred embodiment, a toilet gasket 22 is provided between the toilet body 2 and the toilet lid 19 for added comfort.

[0082] The control system preferably adopts a Mitsubishi PLC system. The toilet in the present invention is a high-pressure toilet, and the flushing mode is a high-pressure mode. Only 200-250 ml of water is required for a single flush, and the flushing process takes only 5 seconds. After 10 seconds of flushing, the control system automatically switches the liquid flow to the control valve 30 to connect with the urine storage tank 18 according to a preset program.

[0083] Specifically, the ventilation system includes an exhaust fan 4 and a first air duct 5. The exhaust fan 4 is installed inside the first air duct 5. One end of the first air duct 5 is connected to the first storage space, and the other end of the first air duct 5 extends vertically upward and communicates with the external atmosphere. The first air duct 5 is preferably equipped with a first rain cap 39 and a lightning rod to effectively protect against rain and lightning. The exhaust fan 4 is electrically connected to the control system. The wall of the sealing ring 11 is provided with a ventilation hole 3. The first air duct 5 is connected to the first storage space through the ventilation hole 3. When the exhaust fan 4 rotates, the gas inside the first storage space and the gas inside the toilet body 2 are discharged into the outdoor atmosphere through the first air duct 5, resulting in a slight negative pressure in the first storage space and the internal space of the toilet body 2, which can effectively prevent odors from entering the indoor space and affecting the air quality.

[0084] Furthermore, when the toilet lid 19 is opened, the sensing device on the rotating shaft of the toilet lid 19 transmits the opening signal to the control system, and the control system controls the exhaust fan 4 to start running, so that a slight negative pressure is formed inside the toilet body 2 through the ventilation system, and the odor inside the toilet body 2 is taken away in time, thereby enhancing the practicality of the toilet.

[0085] Specifically, the plant filter system includes a plant filter 20 and a purified water storage tank 45. The second diversion pipe 23 of the liquid diversion switching system enters from one side of the plant filter 20 and extends to the bottom of the plant filter 20. The other side of the plant filter 20 is connected to the purified water storage tank 45 through a third diversion pipe 31, wherein the falling water elevation of the second diversion pipe 23 entering the plant filter 20 is higher than the overflow elevation of the third diversion pipe 31. In a preferred example, the second diversion pipe 23 is divided into multiple water inlet pipes entering the plant filter 20, and the number of third diversion pipes 31 is multiple and arranged in parallel at intervals.

[0086] Specifically, the plant filter 20 is sequentially arranged from bottom to top with a gravel layer 24, a zeolite layer 25, and a plant layer 26. Multiple baffles 27 are sequentially arranged along the direction of fluid flow, thereby causing the fluid to flow in a serpentine pattern. This multi-layered matrix effectively removes nitrogen, phosphorus, and organic matter from the flushing water, achieving a good purification effect.

[0087] Specifically, the feces storage unit includes a feces storage urn 17, which is provided with a feces extraction port 28, an exhaust port 29, an acid addition port 34, a sewage cleaning port 35, a liquid level radar 36, a feces drop port 37 and a spare port 38. The feces drop port 37 is connected to the bottom of the sealing ring 11. The feces extraction port 28 is used to connect to an external feces extraction equipment. It can be connected to the external feces extraction equipment through the feces extraction pipeline 13 installed on the feces extraction port 28 according to actual needs, and the feces in the feces storage urn 17 can be cleaned regularly.

[0088] An exhaust duct connected to the exhaust port 29 is provided on the body of the feces storage jar 17. The exhaust port 29 is connected to the outside atmosphere through a second air duct 33 extending vertically upward. The top of the second air duct 33 is preferably installed with a second rainproof cap 40 and a lightning rod. The second air duct 33 is provided under the effect of the chimney effect. On the one hand, it prevents the accumulation of gas in the container from causing excessive air pressure and explosion; on the other hand, it can form a slight negative pressure in the feces storage jar 17, preventing the odor in the feces storage jar 17 from emitting into the toilet environment. A pump connection port is provided on the sewage outlet 35, for example, a flange is provided, and the feces storage jar 17 is connected by an outdoor pipe. When the feces are collected and transported, the pump is used to extract the feces through the sewage outlet. The acid addition port 34 is provided in the rear half of the toilet body 2 and is connected to the feces storage jar 17 through a flexible hose.

[0089] Furthermore, the liquid level radar 36 is connected to the control system signal and can detect the liquid level of feces in the feces storage jar 17 to prevent excessive feces in the feces storage jar 17 from affecting toilet use. In a preferred embodiment, the feces storage jar 17 is also provided with an inspection manhole 44, which can be opened for inspection in the event that the feces storage jar 17 becomes abnormally clogged after long-term operation.

[0090] Citric acid can be added to the feces storage jar 17 through the acid addition port 34. Under the action of citric acid in the feces storage jar 17, the fermentation of feces can be reduced, the activity of feces can be maintained, and it is convenient for subsequent use. The flushing water flows through the second diversion pipe 23 and flows into the bottom of the plant filter 20, and passes through the gravel layer 24, the zeolite layer 25, and the plant layer 26 in sequence. The plant layer 26 is planted with emergent plants. After maintaining a certain hydraulic retention time, the purpose of purifying the flushing water is achieved and the flushing water is discharged from the outlet of the third diversion pipe 31 to the adjacent purified water storage tank 45. Both the plant filter 20 and the purified water storage tank 45 are buried underground, which can effectively prevent freezing. The purified water in the purified water storage tank 45 can be effectively collected and reused as relatively clean water. It has great water-saving significance for relatively water-scarce areas. It also reflects the water-saving characteristics of the micro-water flushing system that is suitable for ecological toilets. After a toilet has been used for a period of time, a dedicated person collects feces and urine from the area. The recovered feces are used as a fermentation feedstock for the biogas project, and the fermented biogas residue can be reused as fertilizer, thus reusing the waste resource. Urine is used to extract scarce nutrients such as phosphorus, nitrogen, and urokinase.

[0091] In actual applications, organic wastewater such as hand washing water, bathing water, and laundry water is collected and treated. After collection, it also enters the plant filter, which is separated by a partition. After being treated separately from toilet flushing water, it flows to the purified water collection tank for recycling and reuse, which also has excellent application prospects.

[0092] The working principle of the present invention is as follows:

[0093] When a person goes to the toilet, he first opens the toilet lid 19, and then sits on the toilet body 2 to relieve himself. The feces will fall on the first receiving plate 9, and the urine will flow along the inner wall of the front half of the toilet body 2 into the urine guide groove 14 set at the front end, and then flow to the urine storage bucket 18 through the liquid guide system. At the same time as the toilet lid 19 is opened, the axial flow exhaust fan 4 is powered on and started. When people are urinating, more odor is generated. Under the dual effects of the exhaust fan 4 and the chimney effect, a negative pressure area is quickly formed in the air seal ring 11. Therefore, the odor will enter the air seal ring 11 from the gap between the first receiving plate 9 and the fecal outlet and the urine guide grooves on both sides, and then be discharged to the outside. The forced exhaust during toilet use prevents the odor from dissipating into the toilet room space, which greatly guarantees the toilet experience. After finishing using the toilet, click the control button 12 on the control panel of the ecological toilet to perform the flushing operation. After pressing the control button 12, the control system receives the control signal, and then controls each component to implement subsequent actions:

[0094] On the one hand, the control system controls the first motor 6 to drive the first screw rod 7 to rotate forward, so that the first-stage receiving plate 9 moves backward. During the movement, the first scraper on the first-stage receiving plate 9 scrapes the feces on the first-stage receiving plate 9 to the second receiving plate 10, and then the first motor 6 reverses, driving the first screw rod to reset the first-stage receiving plate 9.

[0095] On the other hand, the control system controls the submersible pump in the water tank 1 to start, and the water stored in the water tank 1 flows to the first receiving plate 9 through the toilet water outlet, thereby flushing the residual fecal particles on the first receiving plate 9. The waste water after flushing flows into the urine drainage trough 14 and reaches the liquid flow control valve 30 through the liquid drainage pipe 15. At this time, the liquid flow control valve 30 has been adjusted to be connected with the second drainage pipe 23 under the control of the control system. Therefore, the flushing water after flushing flows into the second drainage pipe 23 through the liquid flow control valve 30 and then enters the plant filter 20. The control system controls the submersible pump to stop running according to the set time, and then the control system controls the liquid flow control valve 30 to change to be connected with the first drainage pipe 16 so that the fluid can flow to the urine storage tank 18. At the same time, after the first receiving plate 9 returns to its position, the feces has fallen onto the second receiving plate 10. At this time, the control system controls the second motor 41 to rotate, drive the second screw rod 42 to move, and drive the second receiving plate 10 to move toward the second motor 41. The feces on the second receiving plate 10 is pushed by the second scraper. As the second receiving plate 10 moves, the feces falls into the feces storage jar 17 due to the action of gravity. When the second receiving plate 10 moves to the set position, the second motor 41 rotates in the opposite direction to drive the second screw rod 42 to move and drive the second receiving plate 10 back to its position and seal the feces drop port 37 on the feces storage jar 17.

[0096] It should be noted that during the process of urinating or defecating, the operation of the ventilation system can ensure that the odor of the entire device is sucked away, ensuring the air circulation of the entire toilet, which is clean and environmentally friendly. At the same time, when no one is using the toilet, the chimney effect can also ensure that the interior of the toilet body 2 always maintains a slight negative pressure, and the environment around the toilet can always be kept fresh.

[0097] In the extended application of the present invention, according to the specific application scenario, the feces storage urn, plant filter, and purified water storage tank can all be installed underground, which can play an effective anti-freeze role. The plant filter is combined with the household toilet, and the collection and reuse of the purified flushing water is realized, so that the water-flushing toilet does not waste water and saves water resources. The above-mentioned whole set of solutions can be applied to various scenarios such as rural bungalows, scenic area row public toilets, building-type household toilets, etc. It has a wide range of applications and has extremely high practical significance and promotion value.
