The principle of the scheme is as follows: the filler consisting of biological additives, padding and the like is filled in the degradation chamber of the closestool to carry out organic degradation treatment on human excrement, so that the human excrement can be effectively treated in time. In the scheme, the stirring time of the stirring device is fixedly set to be one minute, and the down time of the stirring device is dynamically adjusted by the microcontroller according to the temperature in the degradation chamber. The microcontroller controls the stop time of the stirring device, and the relation of the stop time and the temperature is that Y is-0.243X +20, Y is the stop time of the stirring device, and X is the temperature of the degradation chamber. In order to ensure the activity and the growth environment of the filler, the environment temperature of the closestool is ensured to be above 0 ℃.

The humidity sensor detects the charge amount in the degradation chamber, transfers the charge value to the microcontroller, and further judges the humidity corresponding to the value through the microcontroller.

The middle of the T-shaped nut 24 is connected with an electrode bar 30 through threads, one end of the electrode bar 30, which is positioned in the closestool barrel, is provided with a bulge 23, the other end of the electrode bar is provided with a groove 29, and the bulge 23 and the groove 29 are both provided with threads and are meshed with each other. When two identical electrode rods 30 are fixedly connected through the protrusions 23 and the grooves 29 on the electrode rods 30, the grooves 29 are also used for being connected with the wiring nut, the wiring nut is electrically connected with the heat shrinkage tube and the 3P plug through cables, and when the 3P plug is connected to a matched humidity display instrument, the humidity condition of the environment in the toilet can be known. In actual use, because the electrode rod 30 is in the toilet for a long time, the electrode rod 30 can be damaged and corroded, and the corresponding supplying device is provided for the purpose.

The longer the toilet is in use, the older the filling in the degradation 11 becomes. After the bacteria and the padding in the padding are used for a long time, the charge quantity can be changed correspondingly, and the charge quantities detected by the padding at different stages of the same humidity are completely different. In the scheme, the filler in the first stage is a new filler used for one to five days, the filler in the second stage is a filler used for five to fifteen days, and the filler in the third stage is a new filler used for fifteen to thirty days. The data of the humidity and the filling condition detected by the humidity sensor in the present embodiment are shown in table 1:

table 1

Thus, when the humidity sensor is used for detecting the humidity condition of the filler in the toilet, the filler condition can be known through the range of the charge quantity detected by the humidity sensor, and the specific humidity condition in the toilet can be known through the specific numerical value of the detected charge quantity. The specific charge versus filler condition is shown in table 2:

table 2

Therefore, when the humidity sensor detects the charge amount, the charge amount is transmitted to the microcontroller, and the microcontroller firstly judges the range of the numerical value through a program to determine the filling condition and the filling stage. And judging the humidity of the filling stage according to the value. When the humidity reaches 70%, the microcontroller controls the corresponding mechanism unit to work.

Compared with the humidity sensor on the market, the humidity sensor has the advantages that the charge amount detected by the humidity sensor is more accurate, and further, in the process that the microcontroller controls the components such as the stirring device and the heating device to degrade the excrement through the charge amount, the humidity sensor can degrade the excrement in the closestool more timely and efficiently, a large amount of power consumption can be saved, and the use cost of the closestool is reduced. In order to achieve better performance of the humidity sensor embodying the present solution, the following are comparative results obtained in a series of experiments between the humidity sensor of the present solution and some of the most widely used humidity sensors in the market.

Table 5

The above experiments were all done using controlled variable method, table 3 experiments performed on the basis of the first stage of packing. All the humidity sensors complete the experiment in the same type of closestool, and the filler source is the same batch of filler. The excrement and urine put into the closestool are equal in quantity, and the external environments are also the same. And (5) performing acceptance test after two days. Experimental data show that the filler in the first stage, the humidity sensors of all models including the toilet where the humidity sensor is located in the embodiment, and finally the comparison of the degradation completion rates of human excrement shows that the filler is close to 100%, and the electric quantity consumed for degrading all excrement is not much different.

Table 4 experiments performed on the basis of the second stage of packing. All the humidity sensors complete the experiment in the same type of closestool, and the filler source is the same batch of filler. The excrement and urine put into the closestool are equal in quantity, and the external environments are also the same. And (5) performing acceptance test after two days. Experimental data show that the degradation rate of the excrement of the closestool with the humidity sensor is 98%, and the complete degradation of the excrement is almost realized. The excrement degradation rate of the closestool with the rest humidity sensors of various types is less than 100 percent. Meanwhile, experimental data show that the electric quantity consumed by the closestool of the embodiment is far lower than that consumed by the closestools of other types of humidity sensors.

Table 5 experiments carried out on the basis of the filler of the third stage. All the humidity sensors complete the experiment in the same type of closestool, and the filler source is the same batch of filler. The excrement and urine put into the closestool are equal in quantity, and the external environments are also the same. And (5) performing acceptance test after two days. Experimental data shows that the degradation rate of excrement and urine of the closestool with the humidity sensor is 99%, the complete degradation of excrement and urine is almost realized, the degradation rate of excrement and urine in the closestool with the humidity sensors of other models is far lower than 100%, and the power consumption of the closestool with the humidity sensor is far lower than that of the closestool with the humidity sensors of other models.

The experimental data show that the actual humidity in the toilet can be detected only by the filler in the first stage, namely the new filler, of the toilet where the humidity sensors with the models of HS1101, HI3602 and HM1500 are located, and the toilet can timely and efficiently degrade human excrement through the actual humidity, and meanwhile, the power consumption is saved to the maximum extent. As the use time of the packing becomes longer, the conventional humidity sensor cannot accurately detect the humidity value in the toilet bowl until the second stage and the third stage, and the detection error becomes larger as the use time of the packing becomes longer. Therefore, the microcontroller cannot correctly control the corresponding work of the heating device, the stirring device and other components, and the timely and efficient degradation treatment of the human excrement in the closestool is realized. This also increases the degradation period of human waste, which in turn increases the power consumption of the toilet. The overall performance of the toilet is reduced. Only through the humidity transducer of this scheme can detect out the humidity value that every stage packed, guarantee that microcontroller can realize the timely efficient degradation of the human excrement in the closestool through the efficient work of devices such as regulation and control heating device, agitating unit of this humidity value developments, reduce the power consumption of closestool, save the use cost of closestool.

At the same time, the main gear 602 engaged with the rack plate 601 is rotated accordingly because the main gear 602 is fixed to the rotation shaft 20 and the rotation shaft 20 is fixedly connected to one end of the toilet lid 2.

As shown in fig. 11, the pawl 603 and the ratchet 604 are located in the same plane, and the pawl 603 and the ratchet 604 are adapted to each other. When the main gear 602 rotates, the pawls 603 on the main gear 602 rotate synchronously. When the pawl 603 rotates, it pushes the ratchet wheel 604, which is located on the same plane. The ratchet wheel 604 is coaxially connected to a first gear 605, and the first gear 605 is engaged with a second gear 605.

As shown in FIG. 12, a control method of an environment-friendly urinal biodegradation system comprises the following steps:

the method comprises the following steps: after the integral of the toilet is electrified, the microcontroller controls the stirring device to work, the stirring time of the stirring device is fixed for each minute, the off-time of the stirring device controlled by the microcontroller is linearly related to the temperature of the degradation chamber 11 in the toilet, the relationship between the off-time of the stirring device and the temperature of the degradation chamber 11 is Y-0.243X +20, Y is the off-time of the stirring device, X is the temperature of the degradation chamber 11, and other systems are in a standby state;

step two: when a person uses the closestool, the person stands on the air cylinder body 8, the closestool cover 2 is automatically opened, the microcontroller is automatically closed, and all the systems are completely closed;

step three: after the closestool is used, the closestool cover 2 is closed, the microcontroller is started at the same time, the humidity sensor measures the charge quantity in the closestool, and the microcontroller judges the specific humidity corresponding to the charge quantity value by using a program; the specific judgment comprises the following steps:

step A: when the value is in 3600-3900, the filler in the degradation chamber 11 is in the first stage; whether the value is in 3620 plus 3670 is continuously judged, and if the value is in the range, the humidity reaches 70 percent;

and B: when the value is 2800-3600, the packing in the degradation chamber 11 is at the second stage; whether the value is in 3020-3070 is continuously judged, and if the value is in the range, the humidity reaches 70 percent;

step five: when the humidity in the toilet reaches 70%, the microcontroller starts the electric tracing band 4 and the negative pressure fan to work, and when the electric tracing band 4 starts to work, the microcontroller dynamically changes the off-time of the stirring device according to that Y is-0.243X +20, Y is the off-time of the stirring device, X is the temperature of the degradation chamber 11 along with the increase of the temperature of the degradation chamber 11, the stirring speed of the stirring device is increased, and the degradation of the human excrement in the degradation chamber 11 is accelerated; until the humidity in the degradation chamber 11 is reduced to below 70%, the microcontroller controls the electric tracing band 4 to stop working, the negative pressure fan in the exhaust pipe 7 stops working, at the moment, the temperature of the degradation chamber 11 continuously drops, the microcontroller still dynamically adjusts the stop time of the stirring device according to the condition that Y is-0.243X +20, Y is the stop time of the stirring device, X is the temperature of the degradation chamber; or in the working process of the electric tracing band 4 and the negative pressure fan, when the electric tracing band 4 reaches the maximum set temperature value of 70 ℃, the electric tracing band 4 and the negative pressure fan automatically stop working, the temperature in the degradation chamber 11 also continuously drops, the microcontroller dynamically adjusts the stop time of the stirring device according to the condition that Y is-0.243X +20, Y is the stop time of the stirring device, X is the temperature of the degradation chamber, and when the temperature in the degradation chamber 11 drops to the ambient temperature and the humidity in the degradation chamber 11 is still larger than 70%, the fifth step is repeated until the humidity in the degradation chamber 11 is lower than 70%;

step six: when someone uses the toilet while the microcontroller is working and stands on the cylinder body 8, the system re-enters step two.

When the device is used, the padding and the biological additives are added into the degradation chamber 11, and the addition amount of the padding and the biological additives is preferably about one third of the volume of the degradation chamber 11. When a person uses the toilet, the toilet seat stands on the cylinder body 8, the toilet cover 2 is automatically opened, and the microcontroller is closed. After the closestool is used, a person leaves the cylinder body 8, the closestool cover 2 is automatically closed, the microcontroller dynamically controls the stop time of the stirring device according to the temperature in the closestool, and other systems are in a standby state. After the humidity sensor detects the charge quantity in the toilet, the range of the charge quantity value is automatically judged through a program of the microcontroller to determine the filling condition, and then the humidity is judged through the specific charge quantity.

When the humidity reaches 70%, the microcontroller starts the electric tracing band 4 and the negative pressure fan to work, the degradation chamber 11 is continuously heated in the working process of the electric tracing band 4, and the microcontroller further adjusts the stirring speed of the stirring device along with the change of the temperature. Meanwhile, the humidity in the degradation chamber 11 changes, when the temperature in the degradation chamber 11 is reduced to below 70%, the microcontroller controls the electric tracing band 4 and the negative pressure fan to stop working, and the microcontroller still dynamically controls the stirring device to work according to the temperature. In the working process of the electric tracing band 4, after the electric tracing band 4 is heated to reach the set maximum temperature of 70 ℃, the electric tracing band 4 and the negative pressure fan automatically stop working. The microcontroller controls the stirring device to continue working until the human waste in the degradation chamber 11 of the toilet is completely degraded and the humidity in the degradation chamber 11 is reduced to 70%.

The stirring device stirs the mixture of the feces and the filler, and the exhaust pipe 7 simultaneously discharges the peculiar smell. When the stirring device and the electric tracing band 4 in the toilet bowl work, someone opens the toilet bowl to use, and stands on the cylinder body 8, the control lever 611 props against the micro-control switch 612, the micro-control switch is closed, the toilet bowl cover 2 is opened, all units controlled by the microcontroller stop working, and the microcontroller is correspondingly closed. After the closestool is used, a person leaves the cylinder body 8, the closestool cover 2 is closed, and the closestool returns to work.

The stirring device can continuously stir excrement, padding and biological additives during working, so that the excrement, the padding and the biological additives can be fully contacted, and the decomposition efficiency is improved. Some peculiar smells can be given out at the in-process of stirring, but along with the extension of stirring time excrement and urine and microorganism fungus and carrier intensive mixing, the quick fermentation decomposes into the fertilizer, and most peculiar smell has also been eliminated, and the remaining a small amount of peculiar smell passes through the filter screen under blast pipe 7 and negative-pressure air fan and separates behind the filter screen deodorization purification with nontoxic tasteless gas discharge outdoor. Wherein, the excrement is the nutrient donor of the microorganism bacteria, and the microorganism bacteria are continuously propagated by passage through the excrement to maintain the long-term effective work of the ecological toilet. Meanwhile, the excrement is added to quickly activate the microbial bacteria for fermentation and raise the temperature to 70 ℃, so that the aim of killing worm eggs by one hundred percent is fulfilled. The organic matter decomposed by fermentation is attached to a carrier such as a padding to reach the stock removal amount of 99 percent, namely the weight of the carrier is increased, but the amount is not increased.

The invention can be widely applied to various scenes and environments: firstly, rural toilets are transformed, and the produced fertilizer can be directly used for crop production, so that the toilet environment in rural areas is improved; secondly, the scenic spot toilet is transformed, the scenic spot drainage facility is expensive in manufacturing cost, the traditional public toilet is easy to pollute the environment, the management and maintenance expenses are huge, and the movable degradable public toilet is environment-friendly and can greatly reduce the expenses; due to the fact that the caravan is used for sewage disposal improvement, the first choice of the movable toilet is achieved, and the movable toilet is sanitary, convenient to install and low in cost; and fourthly, the garbage degradation agent can be used for degrading kitchen garbage, and after household kitchen garbage is poured into the degradation closestool, the garbage can be decomposed by using biological bacteria, so that the garbage degradation agent is healthy and environment-friendly, and conforms to the green life style advocated by the state.

the method comprises the following steps: after the integral of the toilet is electrified, the microcontroller controls the stirring device to work, the stirring time of the stirring device is fixed for each minute, the off-time of the stirring device controlled by the microcontroller is linearly related to the temperature of the degradation chamber (11) in the toilet, the relationship between the off-time of the stirring device and the temperature of the degradation chamber (11) is Y = -0.243X +20, Y is the off-time of the stirring device, X is the temperature of the degradation chamber (11), and other systems are in a standby state;

step two: when a person uses the closestool, the closestool stands on the cylinder body (8), the closestool cover (2) is automatically opened, the microcontroller is automatically closed, and all systems are completely closed;

step three: when the closestool is used, the closestool cover (2) is closed, the microcontroller is started at the same time, the humidity sensor measures the charge quantity in the closestool, and the microcontroller judges the specific humidity corresponding to the charge quantity value by using a program; the specific judgment comprises the following steps:

step A: when the value is 3600-3900, the filler in the degradation chamber (11) is in the first stage; whether the value is in 3620 plus 3670 is continuously judged, and if the value is in the range, the humidity reaches 70 percent;

and B: when the value is 2800-3600, the packing in the degradation chamber (11) is in the second stage at this time; whether the value is in 3020-3070 is continuously judged, and if the value is in the range, the humidity reaches 70 percent;

step five: when the humidity in the closestool reaches 70%, the microcontroller starts the electric tracing band (4) and the negative pressure fan to work, when the electric tracing band (4) starts to work, along with the increase of the temperature of the degradation chamber (11), the microcontroller dynamically changes the stop time of the stirring device according to the condition that Y = -0.243X +20, Y is the stop time of the stirring device, X is the temperature of the degradation chamber (11), the stirring speed of the stirring device is increased, and the degradation of the human excrement in the degradation chamber (11) is accelerated; until the humidity in the degradation chamber (11) is reduced to below 70%, the microcontroller controls the electric tracing band (4) to stop working, the negative pressure fan in the exhaust pipe (7) stops working, at the moment, the temperature of the degradation chamber (11) is continuously reduced, the microcontroller still dynamically adjusts the stop time of the stirring device according to the condition that Y = -0.243X +20, Y is the stop time of the stirring device, X is the temperature of the degradation chamber; or when the electric tracing band (4) and the negative pressure fan work, and the electric tracing band (4) reaches the maximum set temperature value of 70 ℃, the electric tracing band (4) and the negative pressure fan stop working automatically, the temperature in the degradation chamber (11) is reduced continuously, and the microcontroller dynamically adjusts the stop time of the stirring device according to that Y = -0.243X +20, Y is the stop time of the stirring device, X is the temperature of the degradation chamber; when the temperature in the degradation chamber (11) is reduced to the ambient temperature and the humidity in the degradation chamber (11) is still higher than 70%, repeating the fifth step until the humidity in the degradation chamber (11) is lower than 70%;

step six: when someone uses the closestool when the microcontroller works and stands on the cylinder body (8), the system enters the step two again.
