[0096] Furthermore, the liquid level radar 36 is connected to the control system signal, and the liquid level radar 36 can detect the liquid level of feces in the feces storage jar 17 to prevent the feces in the feces storage jar 17 from affecting the toilet. In a preferred embodiment, the feces storage jar 17 is also provided with an inspection manhole, which can be opened for inspection when the feces storage jar 17 is abnormally blocked after long-term operation.

[0097] Specifically, the toilet system includes a receiving and sealing system, which includes a first push-pull mechanism, a second push-pull mechanism and a sealing ring 11. The sealing ring 11 is installed inside the toilet body 2 and the top is connected to the first push-pull mechanism that can perform push-pull movements. The bottom of the sealing ring 11 is connected to the sealing box 47. The second push-pull mechanism is arranged between the sealing box 47 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 both be switched between an open state and a closed state, and the first push-pull mechanism and the second push-pull mechanism cannot be in an open state at the same time. 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. When the second push-pull mechanism is in an open state, the first accommodating space is connected to the sealing box 47.

[0099] It should be noted that the end of the first receiving plate 9 facing the urine-conducting groove 14 has a downward tilt angle, for example, 3°, and another example, 7°. When the user urinates, the urine can flow along the tilted first receiving plate 9 into the urine-conducting 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 to the top of the center of the urine-conducting groove 14, so the urine naturally flows into the urine-conducting groove 14 along the tilted flow direction. At the same time, the gap between the first receiving plate 9 and the urine-conducting groove 14 enables 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.

[0100] Specifically, the sealing ring 11 preferably adopts a circular tubular structure with a diameter of 15 cm and a height of 10 cm.

[0101] The control system in the present invention preferably adopts the 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 needed for a single flush, and the flushing process only takes 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.

[0102] Specifically, the filter system includes a plant filter 20 and a purified water storage tank 45, the water inlet side of the plant filter 20 is connected to the second guide pipe 23, and the water outlet side of the plant filter 20 is connected to the purified water storage tank 45 through the third guide pipe 31, wherein the falling water elevation of the second guide pipe 23 entering the plant filter 20 is higher than the overflow elevation of the third guide pipe 31, and the outlet of the second guide pipe 23 extends to the bottom of the plant filter 20, and the plant filter 20 is sequentially provided with a gravel layer 24, a zeolite layer 25, and a plant layer 26 from bottom to top, and the plant filter 20 is sequentially provided with a plurality of partitions 27 along the direction of fluid flow so that the fluid flows in a curved direction.

[0103] Furthermore, the curved flow preferably adopts serpentine flow, and the plant layer 26 is planted with emergent plants. Through the arrangement of the multi-layer matrix, nitrogen, phosphorus and organic matter in the flushing water can be effectively removed, thereby obtaining a better purification effect.

[0104] 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 the third diversion pipe 31. In a preferred example, the second diversion pipe 23 is divided into multiple water inlet pipes to enter the plant filter 20. The number of the third diversion pipes 31 is multiple and they are arranged in parallel at intervals.

[0105] In practical applications, the ecological courtyard of the present invention can collect and treat organic wastewater such as hand washing water, bathing water, laundry water, and flushing water at the same time. After collection, the wastewater also enters the plant filter tank, which is separated by a partition. After being treated separately from the toilet flushing water, it flows to the purified water collection tank for recycling and reuse, which also has excellent application prospects.

The transmission and recovery of feces are realized through a feces pipe 48 and two conveyor belts 46. Urine and flushing water enter the urine storage bucket 18 and the plant filter tank 20 respectively through the liquid conduction switching system.

[0108] The working principle of the present invention is as follows:

[0109] When a person uses the toilet, he first opens the toilet lid 19, and the toilet lid 19 rotates to trigger the exhaust fan 4 to run. The person sits on the toilet body 2 to relieve himself, and the feces will fall on the first receiving plate 9. The urine flows 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 flows to the urine storage bucket 18 through the liquid guide system. 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 feces outlet and the urine guide groove 14, and then be discharged outdoors. The forced exhaust during toileting prevents the odor from being lost to the toilet space at all, which greatly guarantees the toilet experience. After using the toilet, click the control button 12 on the ecological toilet control panel to perform the flushing operation. After the control button 12 is pressed, the control system receives the control signal, and then controls each component to perform subsequent actions:

[0110] First, 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, and the waste water after flushing flows into the urine drainage groove 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 bucket 18.

[0111] Secondly, according to the time set by the system, 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. Then the first motor 6 reverses and drives the first screw rod to reset the first-stage receiving plate 9. After the first receiving plate 9 returns to its position, the feces has fallen on the second receiving plate 10. At this time, the control system controls the second motor 41 to rotate to drive the second screw rod 42 to move and drive the second receiving plate 10 The stool on the second receiving plate 10 moves toward the second motor 41, and is pushed by the second scraper. As the second receiving plate 10 moves, the stool falls onto the conveyor belt 46 in the bottom sealing box 47 due to the action of gravity. The conveyor belt 46 transports the stool to the feces drop pipe 48, and falls into the feces storage urn 17 through the feces drop pipe 48. When the second receiving plate 10 moves to the set position, the second motor 41 rotates in the reverse direction to drive the second screw rod 42 to move and drive the second receiving plate 10 to return to its position and seal the lower part of the sealing ring 11 to separate it from the sealing box 47.

[0112] The flushing water flows through the second guide pipe 23 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 turn. After maintaining a certain hydraulic retention time, the flushing water is purified and discharged from the outlet of the third guide pipe 31 to the adjacent purified water storage tank 45. The plant filter 20 and the purified water storage tank 45 are both 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 a great water-saving significance for relatively water-scarce areas, and also reflects the water-saving characteristics of the micro-water flushing. After the toilet has been used for a period of time, a dedicated person will uniformly collect feces and urine in the area. The recovered feces rely on engineering projects, that is, the high-quality raw material of feces is used as the fermentation raw material of the biogas project. The fermented biogas residue can also be used as fertilizer for secondary use, and the feces and sewage resources are reused for secondary use. Urine is used to extract scarce nutrients such as phosphorus, nitrogen, and urokinase.

[0113] 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, thereby ensuring that the environment around the toilet is always fresh.
