Description

Technical Field

[0001] The present invention relates to the technical field of public health equipment, and in particular to a four-element separation ecological toilet. Background Art

[0002] Ecological toilets are a type of environmentally friendly toilets. They do not pollute the environment, can make full use of various resources, and emphasize the concepts and functions of self-purification of pollutants and recycling of resources.

[0003] Ecological toilets not only reduce or eliminate environmental pollution caused by human feces and sewage, but also reduce the dependence of toilets on external resources, save resources, expand the scope of application of toilets, and improve people's living standards. However, when the existing ecological toilets are in operation, they mainly rely on feces and urine separation devices to complete the separation of feces and urine, but they cannot effectively separate the flushing water, causing a large amount of flushing water to become wastewater, which increases the burden on water treatment. At the same time, there is often a odor of feces and urine volatilization, which is not only not conducive to human health, but also affects the air environment of the toilet, which greatly reduces the practicality of the existing ecological toilets.

[0004] Patent document CN110616787A discloses a toilet, in which the main flushing water pipe includes a starting part of the main flushing water pipe and a vertical part of the main flushing water pipe, the water inlet end of the starting part of the main flushing water pipe is connected to the water outlet, the water outlet end of the starting part of the main flushing water pipe is connected to the water inlet end of the vertical part of the main flushing water pipe, and the water outlet end of the vertical part of the main flushing water pipe is connected to the toilet bowl sewage outlet, but this design still does not solve the defect of odor volatilization.

[0084] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments 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 of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0085] The present invention provides a four-element separation ecological toilet, such as Figures 1 to 13 As shown, it includes a toilet bowl system, a liquid conduction switching system, a secondary receiving and sealing system, a ventilation system, a plant filter system, a feces liquid storage system and a control system. The feces liquid storage system includes a feces storage unit and a urine storage unit. The toilet bowl system is connected to the feces storage unit. The secondary receiving and sealing system is installed on the toilet bowl system. The ventilation system is connected to the secondary receiving and sealing system. The toilet bowl 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 toilet bowl system, the liquid conduction switching system, the secondary 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 the feces and urine are separated from the source, without secondary pollution, odor, good sanitary conditions, and strong practicality.

[0086] Specifically, the secondary receiving sealing system 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 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 both 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, and the ventilation system is connected to the first accommodating space.

[0087] Specifically, the liquid conduction switching system includes a urinary conduction groove 14, a liquid conduction tube 15, a first flow guide tube 16, a second flow guide tube 23 and a liquid flow direction control valve 30. One end of the liquid conduction tube 15 is connected to the urinary conduction groove 14, and the other end of the liquid conduction tube 15 is respectively connected to the first flow guide tube 16 and the second flow guide tube 23 through the liquid flow direction control valve 30. The liquid flow direction control valve 30 is electrically connected to the control system. The control system can obtain status information according to the status of the toilet cover 19 and then control the opening direction of the liquid flow direction control valve 30 to collect and process the flushing water and urine separately.

[0088] In actual applications, different settings should be adopted for different application scenarios. When the number of ecological toilets in the application environment is small, the flow rate of flushing water is small, and the flushing water can be introduced into the plant filter system for treatment, which is especially suitable for application in rural areas with abundant land resources. When the ecological toilets in the present invention are installed in the city, they should be reasonably set according to the actual scenario. In a preferred example, the outlets of the second guide pipe 23 are respectively connected to the plant filter system and the urban sewage network and controlled by the interlocking valve. When the flow rate of flushing water is large, the control system controls the interlocking valve to switch to connection with the urban sewage network. In a variation, the plant filter system can be omitted, and the flushing water is directly discharged into the urban sewage network.

[0089] Specifically, the first push-pull mechanism includes a first motor 6, a first screw rod 7, two first guide rails 8, a first receiving plate 9, a first scraper and a carrier frame 32. The two first guide rails 8 are installed in parallel on both sides of the carrier frame 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 move. The two ends of the first scraper respectively cross the two ends of the first receiving plate 9 and are installed on the carrier frame 32. The bottom edge of the first scraper contacts the first receiving plate 9 and can scrape the top of the first receiving plate 9 when the first receiving plate 9 moves. The second push-pull mechanism includes a second motor 41, a second screw rod 42, two second guide rails 8, a first receiving plate 9, a first scraper and a carrier frame 32. Rail 43, second receiving plate 10 and second scraper 44, the two second guide rails 43 are installed in parallel on both sides of the carrier frame 32, the second motor 41 is connected to the second receiving plate 10 through the second screw rod 42 and can drive the second screw rod 42 to drive the second receiving plate 10 to move, the two ends of the second scraper 44 respectively cross the two ends of the second receiving plate 10 and are installed on the sealing ring 11, the bottom edge of the second scraper 44 contacts the second receiving plate 10 and can scrape the top of the second receiving plate 10 when the second receiving plate 10 moves, the first motor 6 and the second motor 41 are electrically connected to the control system respectively, and the control system can control the actions of the first motor 6 and the second motor 41 according to the settings.

[0090] 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.

[0091] 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 then the control system controls the exhaust fan 4 to start running. When the toilet cover 19 is closed, the touch sensing device and then the control system controls 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 a tap water pipe for water replenishment. For example, a liquid level sensor is provided in the water tank 1 and connected to a 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.

[0092] Furthermore, the toilet water outlet is arranged above the first receiving plate 9 of the secondary receiving sealing system, the water tank water inlet channel and the water tank water outlet channel are respectively provided with a first valve and a second valve, the toilet body 2 is provided with a control button 12, and the control button 12, the first valve, the second valve, the submersible pump, and the sensing device are respectively electrically connected to the control system. In a preferred example, a toilet gasket 22 is also provided between the toilet body 2 and the toilet cover 19, which can play a role in comfort.

[0093] 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.

[0094] Specifically, the ventilation system includes an exhaust fan 4 and a first air duct 5, wherein 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, and the first air duct 5 is preferably installed with a first rainproof cap 39 and a lightning rod, which effectively plays a role of rainproof and lightning protection. The exhaust fan 4 is electrically connected to the control system, and a vent 3 is provided on the wall of the sealing ring 11, and the first air duct 5 is connected to the first storage space through the vent 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, so that the first storage space and the internal space of the toilet body 2 are slightly negative, which can effectively prevent odor from entering the indoor space and affecting the air quality.

[0095] 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.

[0096] 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 the third diversion pipes 31 is multiple and arranged in parallel at intervals.

[0097] Specifically, the plant filter 20 is 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 provided with a plurality of partitions 27 in sequence along the direction of fluid flow so as to make the fluid flow in a serpentine direction. The plant layer 26 is planted with emergent plants. The multi-layer matrix setting can effectively remove nitrogen, phosphorus and organic matter in the flushing water, thereby obtaining a better purification effect.

[0098] 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, and the feces extraction port 28 is used to connect to an external feces extraction device. It can be connected to the external feces extraction device through a 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.

[0099] An exhaust pipe connected to the exhaust port 29 is provided on the body of the feces storage urn 17. The exhaust port 29 is connected to the outside atmosphere through a second air duct 33 extending vertically upward. A second rain cap 40 and a lightning rod are preferably installed on the top of the second air duct 33. 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 pressure and explosion; on the other hand, it can form a slight negative pressure in the feces storage urn 17 to prevent the odor in the feces storage urn 17 from emitting into the toilet environment. A pump connection port is provided on the sewage cleaning port 35, for example, a flange is provided, and the feces storage urn 17 is connected by an outdoor pipeline. When the feces are collected and transported, the pump is used to extract through the sewage cleaning port. The acid addition port 34 is provided in the rear half of the toilet body 2 and is connected to the feces storage urn 17 through a flexible hose.

[0100] 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.

[0101] In practical applications, the present invention can be elevated to the concept of an ecological courtyard, and can collect and treat organic wastewater such as hand washing water, bathing water, and laundry water at the same time. After collection, the wastewater also enters a plant filter tank, which is separated from toilet flushing water by a partition. After being treated separately, the wastewater flows to a purified water collection tank for recycling and reuse, which also has excellent application prospects.

[0102] The working principle of the present invention is as follows:

[0103] When a person uses 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. When the toilet lid 19 is opened, the axial flow exhaust fan 4 is powered on and started. When people are relieving themselves, 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 grooves on both sides, and then be discharged outdoors. The forced exhaust during toilet use 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 implement subsequent actions:

[0104] 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-level receiving plate 9 moves backward. During the movement, the first scraper on the first-level receiving plate 9 scrapes the feces on the first-level 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-level receiving plate 9.

[0105] 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, 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 tank 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. 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 urn 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, drives the second screw rod 42 to move, and drives the second receiving plate 10 back to its position and seals the feces drop port 37 on the feces storage urn 17.

[0106] 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 feces can reduce fermentation, maintain the activity of the feces, and facilitate subsequent use. The flushing water flows through the second guide 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 turn. After maintaining a certain hydraulic retention time, the purpose of flushing water purification is achieved, and it is discharged from the outlet of the third guide pipe 31 to the adjacent purified water storage tank 45. Both the plant filter 20 and the purified water storage tank 45 are buried, 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, which has a great water-saving significance for relatively water-scarce areas, and also reflects the water-saving characteristics of the micro-water flushing four-element separation ecological toilet. After the toilet has been used for a period of time, a dedicated person will collect the feces and urine in the area. The recovered feces will be used for engineering projects, that is, the high-quality raw material of feces will be used as fermentation raw material for biogas projects. The fermented biogas residue can also be used as fertilizer for secondary use, thus making secondary use of feces and sewage resources. Urine is used to extract scarce nutrients such as phosphorus, nitrogen, and urokinase.

[0107] The ecological toilet solution of the present invention can be applied to a variety of scenarios, such as rural bungalow-type, scenic area row public toilets, and building-type household toilets.

[0108] 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.
