Abstract
Description
Technical Field
[0001] The present invention relates to a device for separating feces and urine and flushing without water, in particular to a device that separately collects feces and urine simultaneously, deodorizes and sterilizes the collected urine, and then uses it to flush the toilet, belonging to the technical field of sanitation and environmental protection. Background Art
[0002] At present, some existing feces and urine separation and waterless flushing toilets used in scenic spots have problems that the toilet cannot be flushed and the sanitation and cleaning conditions are poor. In the prior art, the waterless flushing toilet does not separate feces and urine. Both feces and urine are mixed and pulverized for collection. The urine collection is incomplete and not fully utilized, resulting in insufficient urine for flushing and the need to add extra water, which is more inconvenient for use in water-scarce areas. At the same time, a collection bucket is placed under the toilet for feces and urine collection. After the collection bucket is full, manual bucket replacement and removal are required, which is laborious and the conditions are poor. These two major drawbacks and pain points directly affect the use effect of the feces and urine separation and waterless flushing toilet and limit the use scope of this technology and product.
[0003] In addition, although the existing waterless flushing technologies and products on the market solve the problem of flushing the toilet with treated urine. However, there are still some deficiencies in automatic feces and urine identification, effective urine collection, and automatic control systems. For example, some technologies use the length of time a person stays in the toilet cubicle to identify feces and urine. Those with a short time are automatically identified as urine, and the urine is collected into the urine collection tank for flushing the toilet; those with a long time are identified as feces, which are mixed and pulverized with the flushing urine and then enter the fecal sewage collection tank. However, this identification technology will have large errors due to differences in the habits and movement speeds of toilet users or in some specific situations, resulting in incorrect feces and urine identification and directly affecting the use effect. On the other hand, when a toilet user excretes feces and urine at the same time, the urine will be discharged into the fecal sewage collection tank together with the feces, resulting in a reduction in urine collection; the reduction in urine collection will directly lead to insufficient urine for flushing the toilet, and water needs to be added to ensure normal toilet flushing. In some water-scarce areas, it is difficult to supplement water. Summary of the Invention

[0034] The flushing pipe 7 is arranged around the upper edges of the feces collection area 2 and the urine collection area 4, and a plurality of flushing nozzles 8 are installed on the flushing pipe 7.
[0035] The urine in the urine collection box 11 can be used for flushing the toilet after deodorization and sterilization treatment by adding urine treatment agent; when flushing the toilet, the treated urine in the urine collection box 11 is directly flushed through the flushing pipe 7 and the flushing nozzles 8 to the squat toilet 1 after the pressure is increased by the flushing pump 9; the flushed urine is divided into two parts. The urine flushing the urine collection area 4 of the squat toilet 1 still flows back to the urine collection box 11 through the urine outlet 5 and the urine drainage pipe 6 for the next flushing; the urine flushing the feces collection area 2 of the squat toilet 1 falls into the crushing and suction pump 16 below the feces outlet 3 together with the feces, is crushed into fecal slurry and suctioned into the fecal sewage collection box 15.
[0036] It also includes a urine treatment agent storage tank 14, and the urine treatment agent storage tank 14 is communicated with the urine collection box 11 through a pipeline.
[0037] The urine treatment agent storage tank 14 can automatically add the spraying amount of the urine treatment agent according to the number of people using the toilet, or can also control the spraying amount of the urine treatment agent by the natural dripping method of liquid gravity.
[0038] The periphery of the urine collection box 11 is wrapped with a ceramic PTC heating plate 13, and the ceramic PTC heating plate 13 is connected to the control system 21. Specifically, the 1 port of the ceramic PTC heating plate 13 is connected to the 4 port of the relay JK2 in the control system 21, and the 2 port is connected to the GND of the power supply module P1.
[0039] A temperature detector 12 is installed in the urine collection box 11, and the temperature detector 12 is connected to the control system 21. Specifically, the 1 port of the temperature detector 12 is connected to the +5V of the power supply module P1 of the control system 21, the 2 port is connected to the 21 port of the single-chip microcomputer module U1 of the control system 21, and the 3 port is connected to the GND of the power supply module P1.
[0040] A feces and urine collection box weight monitor 19 is installed at the bottom of the feces and urine collection box 15, and the feces and urine collection box weight monitor 19 is connected to the control system 21. Specifically, the 1 port of the feces and urine collection box weight monitor 19 is connected to the +5V of the power supply module P1 of the control system 21, the 2 port is connected to the 5 port of the single-chip microcomputer module U1 of the control system 21, and the 3 port is connected to the GND of the power supply module P1.
[0041] The feces and urine collection box weight monitor 19 monitors the weight of the feces and urine collection box 15. When the warning weight is reached, a voice prompt is issued through the voice alarm 20 to ensure that the feces and urine collection box 15 does not overflow and ensure the normal use of the toilet.
[0042] It also includes a voice alarm 20, and the voice alarm 20 is connected to the control system 21.

[0043] The working principle of the control system 21 is as follows: When the infrared induction sensor 18 detects that a person using the toilet enters the toilet compartment, it sends a signal S1 to port 4 of the single-chip microcomputer module U1; after the infrared induction sensor 18 detects that the person using the toilet leaves the toilet compartment, it sends a signal S2 from port 2 to port 4 of the single-chip microcomputer module U1; after receiving the signal S1 and the signal S2 at port 4 of the single-chip microcomputer module U1, it sends a signal from port 28 to the relay JK1; after receiving the signal, the relay JK1 starts the flushing pump 9 to flush the squat toilet, and at this time, the single-chip microcomputer module U1 starts timing; when the flushing time reaches 3 - 5 seconds, the single-chip microcomputer module U1 sends a signal from port 26 to the relay JK3, and after receiving the signal, the relay JK3 starts the crushing and suction pump 16; at this time, the single-chip microcomputer module U1 starts timing; when the time reaches 5 - 10 seconds, the single-chip microcomputer module U1 sends signals from port 26 and port 28 to the relay JK1 and the relay JK3, and after receiving the signals, JK1 and JK3 synchronously stop the flushing pump 9 and the crushing and suction pump 16. The temperature detector 12 monitors the urine temperature in the urine collection box 11 in real time and sends a signal from port 2 to port 20 of the single-chip microcomputer module U1, and the single-chip microcomputer module U1 judges whether the temperature is normal. If the temperature is lower than 0 - 3 degrees Celsius, it sends a signal from port 1 to the relay JK2; after receiving the signal, the relay JK2 starts the ceramic PTC heating plate to start heating; when the temperature rises above 0 - 3 degrees Celsius, the single-chip microcomputer module U1 sends a signal from port 1 to the relay JK2, and after receiving the signal, the relay JK2 stops the ceramic PTC heating plate from heating; the fecal waste collection box weight monitor 19 monitors the fecal waste in the fecal waste collection box 15 in real time; if the fecal waste is full, the fecal waste collection box 15 sends a signal from port 2 to port 5 of the single-chip microcomputer module U1; after receiving the signal that the fecal waste is full, the single-chip microcomputer module U1 controls the voice alarm 19 through ports 10 and 11 to give a voice alarm, prompting for fecal waste removal.
[0044] The working process of the present invention is as follows: When a person enters the toilet cubicle and squats at the pedal position of the urine-feces separation waterless flushing squat toilet 1, after the infrared sensor 18 senses the person using the toilet, it provides a control signal to the system control circuit module 21 to prepare for the subsequent actions; after the person finishes using the toilet, whether it is defecation or urination, when the person leaves the toilet cubicle, after the infrared sensor 18 senses the person leaving, it provides a control signal to the system control circuit module 21, and the system control circuit module 21 then sends a signal to the flushing pump 9. The flushing pump 9 pressurizes the urine in the urine collection tank 11 through the urine suction tube 10 and then enters the flushing pipe 7. The urine in the flushing pipe 7 is then sprayed out through the flushing nozzle 8 to flush the toilet; after the flushing pump 9 runs for 3 - 5 seconds, the system control circuit module 21 sends a signal to the crushing and suction pump 16, and the crushing and suction pump 16 crushes and sucks and transports the fecal sewage; after the flushing pump 9 runs for another 5 - 10 seconds simultaneously with the crushing and suction pump 16 after the previous 3 - 5 seconds of operation time, they stop running; the crushing and suction pump 16 runs synchronously with the flushing pump 9 for 5 - 10 seconds to crush, suck, and transport the fecal sewage to the fecal sewage collection tank 15 for storage; when the fecal sewage in the fecal sewage collection tank 15 is stored to a certain amount and the fecal sewage collection tank weight monitor 19 monitors and prompts the liquid level for fecal sewage removal, the voice alarm 20 emits a voice prompt for fecal sewage removal. The cleaner or management personnel can arrange the fecal sewage removal work according to the actual situation.
