Description
FIELD OF THE INVENTION
[0001] The invention relates to processing unit in the field of
water, drain water, waste water or mud residue processing. More
particularly, the invention relates to a flushing lavatory used for
stool and urine processing. Its main task is to use circulated
flushing and stool crushing structure, urine collecting device,
double pump flushing device for avoiding sediment accumulation and
automatic urine and stool identification method and device to
combine together so as to configure a no headwater flushing
lavatory. It can only use the urine as flush liquid and realize the
clean flushing, no bad smell from the sewage and controllable
discharge. Users can finish common flushing and running without
applying any control and operation on the lavatory. The invention
is a new design with good applicability and big progress. It's
suitable to be widely spread in the industry field.
BACKGROUND OF THE INVENTION
[0002] The using of flushing lavatory of sanitary ware has the
consanguineous connections with people. Whenever people travel in
suburbs or outer suburbs and whenever people travel by taking
vehicles or live in a hotel, they can't depart from WC. As for most
traveling WC, there is no headwater especially for very remote
areas. For the limitation of headwater, people have to suffer from
the dirtiness. Sometimes people equip the water tank with a certain
amount of water, but when using, people should save water. The bad
smell is rather terrible. On the other hand, the discharge of stool
and urine is also a difficult environment protection problem. At
the district with sufficient headwater, as for water flushing WC,
the environment protection problem still exist. Furthermore, some
users often forget to flush the toilet, then the cleaning of the WC
should depend on the maintenance of the cleaners.
[0003] In order to solving the above problems, some water saving WC
has been innovated. The most widely used is water recycled type.
The representative one is Chinese patent publication number
CN20341714 automatic flushing and water circulated management
device. It's main feature is that between the toilet pan and the
cesspool, setting the absorbing well, medicine sending box,
circulating pump, filter chamber, water discharge case, water
collecting header and the automatic control part including power
supply, controller electronic clock and water level controller. All
these components work together and compose the automatic flushing
and water circulated management device. It can provide the
automatic flushing of stool and urine and at the same time the
water is saved. It's sure that this device has practicability. But
during the real using, it's found that the following disadvantages
still exist:
[0004] 1. Though the automatic flushing and water circulated
Management device has considerable progress in water saving, but it
still can't break away from the headwater eventually, so the water
saving effect isn't high.
[0005] 2. The prior water circulated WC also can't depart from
filtration, so the filtrating device should be set. Then the filter
screen must be changed and maintained timely, thus the labor cost
is increased. It couldn't meet the requirement of cost benefit.
[0006] 3. For the water circulated WC, the circulated water used
also should be changed timely, so it's not convenient to be used
and can't meet people's demand.
[0007] In order to solve the problem of barrage made by the stool
and sheets for the flushing lavatory, a kind of lavatory with stool
crushing mechanism is innovated. The representative one is Chinese
patent publication number CN2101960U electric septic toilet. It
consists of electric motor, hogged pump, water feed magnetic valve,
time-delay controller, shell, feed flexible pipe and discharge
flexible pipe. It has the ability to crush the stool and sheets and
pump them out. Thus the flushing lavatory can depart from the
septic tank and make the stool and sundries having fluidness. The
flushing of the lavatory becomes more unhindered. But it still has
the following limitations:
[0008] 1. Compare with the ordinary flushing lavatory, the electric
septic toilet use more water and couldn't save water. It doesn't
meet the demand of water saving.
[0009] 2. The sewage discharged by the electric septic toilet is
overabundance. It doesn't meet the requirement of environment
protection decrement.
[0010] 3. The sewage discharged by the electric septic toilet isn't
deodorized and disinfected. It doesn't meet the requirement of
harmless environment protection.
[0011] In order to meet the demand of water saving and environment
protection, the related manufacturers try their best to look for
the solutions. Through getting rid of the stale and bringing the
forth the fresh, a kind of plastic bag packed no water flushing
lavatory has been invented. Its main feature is to collect and
transfer the stool and sewage with a plastic bag device and do
concentrated processing. The new lavatory can provide a no water
flushing lavatory for users. Actually, it has advancement, but in
the practical using it is found that it still has some defects. The
defects make the plastic bag packed no water flushing lavatory
couldn't reach the best practical effect. Its defects are as
following:
[0012] 1. Although the plastic bag packed no water flushing
lavatory doesn't need water, but it must have the containing
apparatus made by plastic to finish the collection and concentrated
processing of the stool and sewage. So it needs to set containing
apparatus in addition and the manufacturing cost is increased. It
couldn't meet the requirement of cost effect.
[0013] 2. The using cost for each person of the plastic bag packed
no water flushing lavatory is high and the whole using cost is
increased. It couldn't meet the economic and practical requirement
of users. The economic profit isn't high.
[0014] 3. The main defect of plastic bag packed no water flushing
lavatory is it is difficult to degrade the produced mixture sewage
of plastic and stool, especially the used plastic is unable to be
decomposed. The concentrated stool and urine hasn't done the
harmless processing and it's difficult to eliminate and utilize
them. Then it has no industry utilizing value.
[0015] In order to meet the demand of water saving and environment
protection, although many manufacturers try their best to do
innovation, but no suitable design has been finished. Because the
flushing lavatory should not only meet the demand of water saving
and environment, but also should be economical and practical, so a
general product can't provide the above multifunction. It's obvious
that this is the anxious problem need to be solved. It is a target
need to be improved in the field of lavatory manufacturing that how
to design a economical and practical multifunction flushing
lavatory with the advantages of water saving, environment
protection and low cost. Thus it can be seen that the above prior
flushing lavatories have many defects and need to be improved.
[0016] Whereas the above defects in the prior flushing lavatories,
the inventor has done much research and innovation for the purpose
of inventing a flushing lavatory with new structure based on many
years design and manufacturing experience and his professional
knowledge. In order to invent a flushing lavatory with new
structure, which can improve the structure of the conventional
flushing lavatory and make it more applicable, the inventor has
done much research and innovation. After many times of samples
studying, finally, the invention with good practical value has been
created.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0051] The detailed description of preferred embodiment,
structures, features and the effects of the flushing lavatory
submitted in accordance with the invention will be described as
following, combining with the drawings and its better
embodiments.
[0052] Refer to FIG. 1, it is the first example of the invention,
flushing lavatory with the circulated flushing and stool crushing
structure A. It consists of toilet pan 3, crushing pump 5, flush
liquid pump 28 and circuit control device 1. Wherein:
[0053] The said toilet pan 3, a crushing pump 5 is mounted at the
outlet valley of the bottom of its back part. In the bottom near
the front of the pan 3, a crush pipe 8 is connected and its stool
crushing nozzle is open and fixed at the front bottom of the pan 3,
against the stool. The magnetic valve 12 controlling the open and
close of the crush pipe 8 is set in it. The crush pipe 8 is
connected with one side of the outlet valley of the crushing pump 5
and at the bottom of the crush pipe, a stool collecting pipe 22 is
set. A magnetic valve 9 is mounted in the stool collecting pipe 22
to control the open and close of it. The other end of the pipe 22
is an open end, it can discharge the rejection out of the
system.
[0054] The crushing pump 5 is fixed in the outlet valley of the
bottom of the toilet pan 3. The pump consists of motor 7,
centrifugal flabellum 6, crushing tools 4 and other components. The
motor 7 is fixed at the lateral portion of bottom of the toilet pan
3 and its output axis is set cross the inner cavity at the bottom
of the pan 3. The centrifugal flabellum 6 and crushing tools 4 are
mounted on the output axis. With the centrifugal effect, the
centrifugal flabellum sucks the sewage in the toilet pan 3 into the
crushing pump 5 and pump it out from the outlet. The crushing tool
4 fixed in the top of output axis will crush the solid flowing into
the pump 5 at this time.
[0055] The said flush liquid pump 28 and a flush pipe 20 are set at
the front of the toilet pan 3. The outlet nozzle 16 of the open end
of the flush pipe 20 is mounted at the front of toilet pan 3, the
other end is connected with the flushing pump 28. One end of the
flush pipe 20 is connected with the flush liquid or headwater, the
other end--the outlet nozzle 16 is set at the front tip of the
toilet pan 3, so that the flush liquid can reach all the positions
the sewage will go. The liquid will flow into the toilet pan 3 with
the action of flush liquid pump 28.
[0056] The circuit control device 1 controls all the above
electrical appliances.
[0057] The above structures combine together and configure the
invention, the flushing lavatory with the circulated flushing and
stool crushing structure.
[0058] Refer to FIG. 1, when the invention works and flushes the
stool, under the control of the circuit control device 1, it will
start the flush liquid pump 28 and make it delay for a certain
time. Through the outlet nozzle 16 of the flush pipe 20, a definite
amount of flush liquid or water flows into the pan of the toilet 3
and then the crushing pump 5 rotates. The magnetic valve 12
controlling the open and close of the stool crushing pipe 8 opens
and the flush liquid will form a positive circulation in the
ring-shaped path made by toilet pan 3, crushing pump 5, crushing
pump magnetic valve 12, crush pipe 8 and toilet pan 3. After the
circulation lasts for a certain time, the stool in the pan 3 will
be flushed into the crushing pump 5 to crush and it will mix with
the flush liquid and become a gruel liquid (FIG. 1 is this working
state).
[0059] After the above working procedure is finished, under the
control of the circuit control device, the magnetic valve 9
controlling the open and close of the stool collecting pipe 22
opens and the crushing pump 5 rotates. The sewage in the toilet pan
3 will be discharged out of the lavatory system through the
crushing pump 5, the magnetic valve 9 and stool collecting pipe 22.
At the same time, at the bottom of the toilet pan 3 there is small
amount of gruel stool liquid without solid left. Restart the flush
liquid pump 28, through the outlet nozzle 16 of the flush pipe 20
connected with the flush liquid or headwater at the front of the
toilet pan 3, the pan is easy to be flushed clean. The stool
crushing lavatory adding the above circulated flushing structure
would decrease the flush liquid need to be used for each stool
flushing from 6-12 liter to 0.5 liter and has no effect on the
flushing result.
[0060] Refer to FIG. 2, the second embodiment of the invention, the
flushing lavatory with circulated flushing and stool crushing
construction. It has the same structure with the first embodiment.
The difference is the structure of the flush pipe is designed to
another kind. The flush pipe 20, its flushing structure is setting
a magnetic valve 38 to control its open and close. The magnetic
valve 38 is controlled by instructions of the circuit control
device 1. The flush pipe 20, one end of it is compressive flush
liquid or headwater, and the other end is an outlet nozzle 16,
which is set in front of the toilet pan 3 so that the nozzle 16 can
make the flush liquid reach all the positions the sewage will go.
Under the control instruction of the circuit control device 1, the
magnetic valve 38 opens and the flush liquid will flow into the
toilet pan 3 to flush with the action of the headwater
pressure.
[0061] Refer to FIG. 3, the third embodiment of the invention. It
has the same structure with the first and second embodiment. The
difference is a urine collecting device B is set, then it becomes
the invention, flushing lavatory with urine collecting device. The
flushing lavatory can be installed on the ordinary stool crushing
lavatory. It includes the toilet pan 3, the crushing pump 5 and the
flush liquid pump 28, especially has a urine collecting device B.
The urine collecting device B consists of urine collecting pipe 10,
urine collecting box 26 and circuit control device. Wherein:
[0062] The toilet pan 3, the crushing pump 5 and the flush liquid
pump 28 have the same structures with the first embodiment. It's no
need to describe it anymore.
[0063] The urine collecting pipe 10 is connected with valley of the
discharge outlet at the back and bottom of the toilet pan 3. At the
bottom of the urine collecting pipe 10, a stool collecting pipe 22
is connected, which has a magnetic valve 11 controlling the open

of the toilet pan 3 and through the crushing pump 5, urine
collecting pipe 10 and urine collecting magnetic valve 11 into the
urine collecting box 26, then urine collecting is finished. If
there is stool in the toilet pan 3, after the urine collecting
magnetic valve 11 opens, as the stool is uneasy to flow and the
crushing pump doesn't work, it can prevent the stool flow into the
urine collecting box 26 and the separation of liquid and solid is
realized. Then the effective collection of urine in the stool is
ensured. When flushing the stool, under the control of the circuit
control device 1, the flush liquid pump 28 starts and draws the
urine out of the urine collecting box 26. Through the outlet nozzle
16 of the flush pipe 20 connected with the flush liquid or
headwater at the front of the toilet pan 3 to discharge and flush.
At this time, the flushed urine and the flush liquid flow into the
toilet pan 3 with the action of flush liquid pump 28 rapidly. The
mixed flush liquid will flush the pan rapidly and the pan is easy
to be flushed clean. At the same time, the stool collecting
magnetic valve 9 opens and the sewage will be discharged out of the
lavatory system through the stool collecting pipe 22. When only
flushing the urine, as there is no stool in the toilet pan 3, all
the urine and flush liquid can be recovered and utilized. The urine
collecting magnetic valve 11 opens under the control of the circuit
control device 1. All the flush liquid will be conducted into the
urine collecting box 26. With the urine collecting device, the
lavatory may have the function of automatic flushing under the
intelligent control.
[0068] Refer to FIG. 4, the fourth embodiment of the invention. It

medicine pot. Another end of the pipe 19 is mounted on the urine
collecting box 26 or connected with the urine conduct pipe 10 then
to the urine collecting box 26. A medicine adding magnetic valve 15
controlling the open and close of the urine conduct pipe 10 is set
between the urine conduct pipe 10 and the medicine pot 17, which is
controlled by the circuit control device 1.
[0070] The circuit control device 1 controls the above electrical
appliances and the magnetic valve.
[0071] The above structures combine together and configure the
invention, the flushing lavatory with the automatic liquid medicine
adding device.
[0072] When the invention works, the open and close of the urine
conduct pipe is controlled by the medicine adding magnetic valve
15. The medicine adding magnetic valve 15 is controlled by the
circuit control device 1. With the circuit control device 1 the
medicine adding magnetic valve 15 can open once during every urine
recovery. It makes the sterilized and environment protection liquid
medicine 18 stored in the medicine pot 17 mix with the urine
flowing from the outlet of the toilet pan 3 and becomes a mixed
flush liquid. The flush liquid can eliminate the bad smell of the
urine in a certain time and then the invention has the function of
automatic environment protection liquid medicine and bad smell
eliminating.
[0073] Refer to FIG. 5, the fifth embodiment of the invention. It
has the same structure with the third embodiment. The difference is

[0078] The circuit control device 1 controls the above electrical
appliances. The above structures combine together and configure the
invention-no headwater flushing lavatory with double-pump flushing
device.
[0079] When the invention works, under the control of circuit
control device 1, the lower flush liquid pump 27 can draw out the
urine sediment from the lower part of the urine collecting box 26.
Through the lower liquid conduct pipe 21, the urine sediment will
reach the lower liquid nozzle 40 and spray at the back of the
toilet pan 3 accumulating the stool and urine and flush it. And
then the upper clean liquid pump 28 will draw out the urine clean
liquid from the upper part of the urine collecting box 26. Through
the upper clean liquid conduct pipe 20, the urine clean liquid will
reach the clean liquid nozzle 16 and also spray at the back of the
toilet pan 3 accumulating the stool and urine and flush it
repeatedly. Thus, as the lower flush liquid pump 27 and the upper
clean flush liquid pump 28 pump the urine flush liquid together,
the toilet pan 3 can be finally flushed clean without urine
sediment left. The urine sediment liquid in the urine collecting
box 26 is consumed during working and it will not accumulate more

at the outlet of the lower end of the stool collecting pipe 22 of
the toilet pan 3
[0090] The stool discharge pump 24 is set at the bottom of the
stool collecting box 25 and a discharge pipe 23 is connected with
it. The discharge pipe 23 extends upward out of the stool
collecting box 25 and its outlet is connected with the external
collection place.
[0091] When the invention works, with the above structures, the
bottom of the stool collecting pipe 22 in the toilet pan 3 is
connected with stool collecting box 25. Under the control of the
circuit control device 1, at the beginning of the defecating or
pissing, the timing starts according to the defecating and pissing
beginning signal sent by the detection device 2. During the
defecating and pissing, the urine collecting magnetic valve 11
opens and the urine will flow into the urine collecting box 26
through the crushing pump 5, urine collecting pipe 10. The
separation of liquid and solid is realized. During the urine
collection, the circuit control device 1 orders the medicine adding
magnetic valve 15 open and makes the environment protection liquid
medicine 18 flow into the urine collecting pipe 10 through the
medicine pot 17, liquid medicine conduct pipe 19 and mix with the
collected urine. The mixed liquid will flow into the urine
collecting box 26 and the change from the urine into the flush
liquid is finished. If it is urine, when the user leaves the WC,
the upper clean flush liquid pump 28 and the crushing pump 5 start.
The flush liquid in the urine collecting box 26 will be pumped out
by the upper clean flush liquid pump 28 and flow into the toilet
pan 3 through the flush liquid pipe 20 and flush it. Then it will
be sucked and pumped into the urine collecting pipe 10 with the
urine by the crushing pump 5 and will flow back into the urine
collecting box 26. If it is stool, the urine collecting magnetic
valve 11 closes and the stool crushing magnetic valve 12 opens.
Start the lower flush liquid pump 27 and let it last for a certain
time. The lower flush liquid about 0.2-0.3 liter with the urine
sediment will spray into the toilet pan 3 through the lower liquid
conduct pipe 21, one-way check valve 14 and nozzle 40. Start the
crushing pump 5 and the flush liquid will have a circular flow in
the path formed by the toilet pan 3, crushing pump 5, stool
crushing pump 8, toilet pan 3. With the help of circular flow, the
stool will be pushed into the crushing pump 5 to crush and it
becomes a gruel liquid with the flush liquid. Then the stool
crushing magnetic valve 12 closes and the stool collecting magnetic
valve opens. It makes the gruel liquid flow into the stool
collecting box 25 through the stool collecting pipe 22. Then start
the upper clean flush liquid pump 28 and it pumps the upper clean
liquid about 0.2-0.3 liter into the toilet pan 3. The gruel stool
liquid left in the toilet pan 3 will be flushed clean and pumped
out by crushing pump 5. Finally, it will flow into the stool
collecting box 25 through the stool collecting pipe 22. The gruel
stool liquid left in the stool collecting box 25 will flow out of
the flushing lavatory in suitable time (for example, in the fixed
discharge time or someone is cleaning) and the controllable
discharge is realized.
[0092] Refer to FIG. 7, is the statistical chart concerning service
time of defecating or pissing used by the stool and urine automatic
identification method and device. It shows the rule of consuming
time of defecating and pissing for a person in an ordinary WC by
the plane rectangular coordinates. It is the statistical chart
drawn according to the sampling situation of the consuming time of
defecating and pissing for several hundreds of people's continuous
using in a real WC. There are two curves. Wherein: the real line
shows the rule of the service time of the WC and the correspondent
number of people. The vertical coordinate is the differential of
the service time and service people. The abscissa represents the
service time in the WC. The imaginary line shows the proportion of
the number of people in the total counted people finishing use the
WC before a specified time. Its vertical coordinate is the
percentage and the abscissa is the service time in the WC.
[0093] From the real line in FIG. 7, we can see the three peak
values respectively show the man pissing, woman pissing and peak
time of defecating. From the imaginary line, we can see that 90% of
the users' service time is in the time of 0-t0. During this period
of time, it almost is pissing.
[0094] Through the actual test, no testers can finish the
defecating in the time less than t0. Then we can get the following
conclusion: a time t0 exists and in the above time, nobody can
finish the defecating. According to the actual test, t0 is about
between 1 minute to 1.5 minutes.
[0095] The above conclusion finds a method of automatic stool and
urine identification for purpose of identifying the stool and urine
by utilizing the service time in the WC. According to the above
identification method, a stool and urine identification device E
for the automatic identification of stool and urine is set in the
invention.
[0096] The stool and urine automatic identification device E
consists of circuit control device 1, detection device 2 and the
program circuit set in the circuit control device 1 to identify the
stool or urine. The detection device 2 is set as a sensor and
connected with the input end of the circuit control device 1. It
can transfer the detected signal to the circuit control device
1.
[0097] Refer to FIG. 8, the logical determination sketch map of the
stool and urine identification device E of the circuit control
device of the flushing lavatory. The circuit control device 1 in
the stool and urine identification device E not only can start the
procedure of the flushing of the toilet pan 3 according to the
user's leaving signal provided by the detection device 2, but also
can start the timing based on the signal of the user entering the
WC provided by the detection device 2. The timing procedure will
end until the detection device 2 provides the user's leaving
signal. The circuit control device 1 can identify the stool or
urine based on the length of time made by the timing device. That
is, when the using time is shorter than a specified eigenvalue t0,
it is certain that it isn't the stool in the WC. Because some users
spend long time when pissing, then the identification method can't
separate all the stool or urine correctly, but it is certain that
it can identify the number of people defecating. The reason why
this method doesn't call "urine automatic identification method" is
because the users leaving the WC in the time of t0, may piss or may
do nothing.
[0098] Refer to FIG. 9, the control device of the no headwater
flushing lavatory consists of human body detection device 2, stool
box liquid level sensor 29, urine box liquid level sensor 30,

are execution units. The said control circuit 1 receives the signal
of liquid level, temperature and occupancy transferred from the
above sensors and decides which execution unit works, the length of
working and working times.
[0100] Refer to FIG. 10, the circuitous philosophy diagram of the
circuit control device of the invention, flushing lavatory with no
water flushing system. The circuit control device 1 consists of the
first part direct current power supply part 1, the second part
sensor interface part 2, the third part control circuit part 3, the
fourth part execution units driving circuit part 4. The sensors
transfer the signals to the control circuit 3 through the sensor
interface 2. After judged and calculated by the control circuit,
the signals are transferred to the execution units driving circuit
4. Through the power magnification of the driving circuit 4, it
will push every execution unit to work and operate. Wherein:
[0101] Refer to FIG. 11, the circuit diagram of the circuit control
device of the invention, flushing lavatory with no water flushing
system, we can see the four parts of the circuit block diagram
listed in FIG. 10. Wherein:
[0102] The first part is the direct current power supply circuit
part 1, it consists of double voltage changer, bridge rectify
circuit, three-terminal voltage regulator and its protective
circuit diode and filter circuit. The alternating current inputs
into the primary side of the changer and through the secondary
side, outputs two lower voltage AC. And then, it inputs into the
bridge rectify circuit and changes into a pulse direct current.
Through the filter, it becomes a direct current. Through
three-terminal voltage regulator and filter, it becomes a 5 v DC
and outputs two general ground +5 v DC.
[0103] The third part is the core control circuit part 3, it
consists of chip microcomputer AT90S8535 and its attached circuit.
The attached circuit includes crystal vibration providing operating
frequency, the resistance and capacitance used for upper reset, the
four or negation gate integrated circuit used for the gating of the
liquid level sensor, warning buzzer, the interface used for the
serial programming and on-line communication and the interface used
for connecting the key board and LED indicator. The crystal
vibration is connected with the foot 12, 13 of the input end of the
crystal vibration of the chip microcomputer. The two ends of the
crystal vibration are connected with two grounding capacitances.
The upper reset resistance is connected with the foot 9 of the chip
microcomputer and the foot 9 is connected with the grounding
capacitance. The negative pole of the buzzer is connected with the
foot 20 of the chip microcomputer and the positive pole is
connected with the +5 v voltage. The interface used for the serial
programming and on-line communication is respectively connected
with +5 v and the foot 10, 5, 6, 7, 8, 9, 11 through the connection
terminal of the foot 8. At the same time, the foot 11 is grounding
and the foot 10 is connected with +5 v, a special line for the chip
microcomputer. The interface of the keyboard and LED indicator is
respectively connected with +5 v, ground and the foot 3, 4, 17, 39,
38.
[0104] The chip microcomputer AT90S8535 is produced by ATMEL
Company in USA, it is a eight bit AVR chip microcomputer product.
It has the functions of the inner n. watchdog, ten bit ADC
converter, SPI synchronous serial communication, serial download
program, pulling high, high resistance input model and so on. The
circuit can transfer the voltage analog signal sent by the
temperature sensor into the digital signal through the ten bit ADC
converter connected at the foot 33, 34. The circuit uses the
external clock/counter on the T1 of foot 2 to do frequency test on
the pulse signal sent by the liquid level sensor. The circuit also
use the inner pulling high function on the foot 30,37 to identify
the human body detection switching signal and send the instruction
to the correspondent execution units driving circuit through the
logical decision. The chip microcomputer occupies the +5 v voltage
output by the DC power circuit on foot 10 individually and another
+5 v voltage output by the DC power circuit provides the DC voltage
of the whole circuit except the chip microcomputer. At the same
time, the above DC voltage is connected on the external interrupt
input interface INTO on the foot 16 of the chip microcomputer. The
interrupt input interface is set as trailing edge trigger. At the
moment of electricity failure, as the power consumption of the chip
microcomputer is less, the +5 v voltage applying for the chip
microcomputer will keep for a very short time after the whole
circuit powers fail. At this time, the chip microcomputer will
detect the power-failure through the external interrupt input
interface and protect the state field before the power-failure, so
that the field can be restored and the work can be done
continuously when powers on again. The design is against the effect
of the short time power-failure or the voltage disturbance on the
program decision.
[0105] The second part is the interface circuit of the sensor 2.
The interface circuit of human body detection device consists of
connection terminal and capacitance connected on the foot 36, 37.
The above two feet are set as input and its states are pulling
high. They are connected with ground and pulling low by the sensor
to judge if there is person or not.
[0106] The liquid level sensor, its connection terminal of the
interface is connected with the four or negation gate integrated
circuit. The four or negation gate integrated circuit can gate the
square wave input by the two liquid level sensors through the
connection as shown in the FIG.. When the control end is gated to
connect with the foot 1 of the chip microcomputer, the square wave
inputs into the foot 2 of the chip microcomputer. The foot 1 is set
as output and the foot 2 is set as the high-resistance state or
pulling high state of the input. The high-low of the liquid level
is determined in accordance with the frequency of the square wave
sent by the liquid level sensor.
[0107] The temperature sensor, its interface circuit consists of
connection and capacitance connected on the foot 33, 34 of the chip
microcomputer. The two feet are set as input and present as the
high-resistance state. The high-low of the temperature is
determined by the voltage value sent by the temperature sensor.
[0108] The fourth part is the execution units driving circuit 4. It
consists of thirteen complete same driving elements. Every driving
element includes optical coupling driving circuit, supper power
crystal brake tube, protective high pressure proof capacitance and
piezoresistance, wherein:
[0109] The optical coupling driving circuit, its input end is
connected with the signal output end of the chip microcomputer and
+5 v. The output end of the optical coupling is connected with the
input end of the supper power crystal brake tube.
[0110] The supper power crystal brake tube, its output end is
connected with the parallel connected high pressure capacitance,
piezoresistance and execution units. As the chip microcomputer
outputs the low electric potential, the light-emitting diode in the
optical couple will brighten and the light-sensitive and two-way
crystal brake tube in its inner output end conducts and drives the
high power two-way crystal brake tube conduct so as to drive the
correspondent execution unit. The zero passage driving circuit is
set in the light-sensitive and two-way crystal brake tube of the
optical couple driving circuit. It will conduct at the moment of
receiving the optical signal and meeting the zero AC voltage. Thus,
it can avoid the appearance of power waveform disorder caused by
the sudden loading on the execution unit, and it also can avoid the
damage of circuit and the loss of the execution unit and the
program of the chip microcomputer.
[0111] The high pressure capacitance has the function of absorbing
the high-frequency clutter.
[0112] The piezoresistance conducts at the time of overvoltage and
has the protective function on the circuit and execution unit.
[0113] The output end of the above thirteen paths execution units
driving elements is connected with the thirteen output base pins
14, 15, 18, 19, 21, 22, 23, 24, 25, 26, 27, 28, 29 of the chip
microcomputer and the input end is connected respectively with
crushing pump motor 7, urine collecting magnetic valve 11, stool
collecting magnetic valve 9, stool crushing magnetic valve 12,

controlled by the correspondent base pin of the chip
microcomputer.
INDUSTRY APPLICABILITY
[0114] The invention has obvious advantages and beneficial effect
comparing with the prior art. From the above technical manners we
can see that the invention has completely no the limitations of the
prior flushing lavatory when using and its structures are more
reasonable and changeful. Thus it has the considerable utility and
wide value of use in the industry. The advantages of the invention
will be described as following:
[0115] 1. The invention, the flushing lavatory with the circulated
flushing and stool crushing structure. Aim at the disadvantage of
the prior flushing lavatory-too much consumption of water, the
invention can crush the stool and sheets and make the discharged
sewage have better fluidity and stated pressure and delivery lift.
During the procedure of stool crushing, the discharged sewage is
transferred back into the toilet pan through the pipe and it makes
the mixture of the flush liquid and sewage form a circulation along
the toilet pan, crushing pump, pipe, toilet pan. If the time is
permitted, the limited flush liquid can make the liquid flow going
through the stool to become much at discretion. Whenever how
difficult the stool is to be flushed, it can be crushed and flushed
clean. The crushed stool will mix with the flush liquid as a gruel
liquid and finally, the sewage will be discharged out through the
pipe. When the procedure is finished, a small amount of gruel stool
liquid may be left. At this time, use the flush liquid to flush it
again. So the invention has the efficacy of using the discharged
flush liquid to recycle and flush the toilet pan and maximum water
saving.
[0116] 2. The invention, the flushing lavatory with urine
collecting device. Recur to setting the magnetic valve on the pipe
of the urine collecting device and utilize the gravity of the urine
and its good fluidity and the bad fluidity of the stool, and also
recur to the obstruction of the crushing pump on the stool as it is
at rest, the urine is conducted into the urine collecting box from
the outlet of the crushing pump through the pipe. It makes the
flushing lavatory has the function of urine collection, and at the
same time has no effect on the function of flushing, stool
discharge, stool crushing and so on. Then the invention can use the
castoff to flush the lavatory and needn't use water.
[0117] 3. The above urine collecting device can have automatic
medicine adding device. The liquid medicine is a kind of liquid
environment protection medicament with the function of
deodorization and disinfection and it makes the processed stool and
urine have no bad smell and innocuous and reach the demand of
innocent. Thus it can meet the requirement of users and become more
applicable. In order to make the medicine adding more reasonable,
uniform and convenient, the invention stores the medicine in a
medicine pot for long use. The environment protection medicine in
the medicine pot is conducted into the urine collecting box through
the pipe and the open and close of the pipe is controlled by the
magnetic valve. Thus, when the magnetic valve is opening for a
certain time, a certain amount of environment protection medicine
will flow into the urine collecting box. Then the invention has the
effect of automatic environment protection medicine adding.
[0118] 4. The invention, flushing lavatory with double-pump
flushing device. Recur to the double-pump flushing device and aim
at the problem that the continuous accumulated sediment in the
urine has bad effect on the flushing, the invention sets two pumps
at the different level of the liquid storage box and draw out the
liquid respectively. First, use the lower liquid with sediment to
flush the lavatory and then use the upper clean liquid to flush.
The lavatory is flushed in order and the urine sediment
accumulation is avoided.
[0119] 5. The invention, the flushing lavatory with the stool and
urine automatic identification device discloses a stool and urine
automatic identification method and its device. It can identify the
stool or urine by the length of user's service time in the WC and
can recognize the non-stool. The device not only can borrow the
ideas from the thinking of using the user's leaving signal provided
by the detection device to start the flushing of the stool or urine
in prior WC, but also can utilize the user's leaving signal
provided by the detection device to make the control system do
pissing determination on user's action according to the service
time from user entering the WC to leaving. Although the device
can't decide that the user's action whose service time is longer
than a eigenvalue is defecating by all means, but it can decide
that the user's action whose service time is shorter than a
eigenvalue isn't defecating. Having this distinguish method and
identification device, for the user's action of non-stool, the
simple flushing can be done by the flushing and stool crushing
lavatory and the crushing procedure isn't needed. As the used flush
liquid has no stool, so the urine collecting device can be
reclaimed into the urine collecting box for reservation and needn't
to be wasted. Thus, with the stool and urine automatic
identification method and its device, the stool and urine can be
identified in many user's actions and the system can cast off the
complex and uncertainty of the manual determination. The invention
has the function of processing the stool and urine with different
modules automatically.
[0120] The sample of the flushing lavatory made in accordance with
the above devices and methods, through a period of actual test, the
following data is get: the urine produced by each person for each
service is 0.2-0.3 liter and most of the urine can be collected.
After being collected, the urine will mix with the environment
protection liquid medicine about 0.1% and become the flush liquid
for the lavatory without bad smell and poison. It can keep no
off-flavor for about one month. It makes the processed stool
harmless. The invention can meet the requirements of users and
become more applicable. The consumption of the flush liquid for
each person when flushing the stool is only 0.5 liter. Calculate
the reclaimed urine produced by defecating, the actual consumption
of the urine is 0.2-0.3 liter, that is consumption of the urine for
one person. When flushing the urine, all the urine and flush liquid
are reclaimed into the urine collecting box. So it doesn't consume
the flush liquid, on the contrary, the urine for one person is
added. Thus, as the proportion of the stool and urine can keep
equal, the flush liquid in the urine collecting will not used up.
Actually, the number of people pissing is much more than
defecating. That means the flushing system is difficult to face the
problem of flush liquid used up. For example, the sewage temporary
storage device of a WC whose capacity is two hundred liters, the
discharge periodic time can be extended to more than four days.
People can't smell the odor of the sewage outside one meter.
Especially, the sewage has good fluidity when discharged into the
sewer and can change into coarse paper solid in one day after it
has been discharged on the ground surface. The capacity and weight
can be reduced several decade times. After one month, people can
uncover the coarse paper solid and the ground surface has no
strange shape. It meets the requirement of environment
protection.
[0121] 6. The invention, no headwater flushing lavatory, recur to
the no headwater flushing system, use the urine collecting device
to collect the urine and utilize the water saving function of the
circulated flushing and stool crushing lavatory to make the urine
become the enough flush liquid for lavatory flushing. And it also
uses the stool and urine automatic identification method and its
device to cast off the dependent on the manual work. Finally, the
good effect of flushing the toilet pan independent of headwater and
manual water upbound is totally realized. It can be verified from
the above examples of exploitation that the disclosed devices and
methods of the invention combine together effectively, the flushing
lavatory can change the limit urine into the sufficient supply of
flush liquid. The invention makes the flushing of the lavatory cast
off the dependent on the headwater completely and the discharge
without bad smell and controllable. The cleaning and maintenance
are very convenient. It also can let the normal operation of the
lavatory cast off the dependent on the user's consciousness and
make the lavatory become the automatic "fool WC" in the real
meaning. In addition, in the place inconvenient to discharge, the
flushing lavatory system can store the random discharged sewage
temporarily and discharge it under control. It makes the lavatory
more applicable in using and meet the requirements of users on the
flushing lavatory products. The holistic profit can be increased
and the invention also has considerable utilizing value in industry
and can be widely spread.
[0122] 7. The structural design, the using practicability and its
cost benefit of the invention are all meet the requirement of
industry development. The disclosed structure is the innovated
design and unprecedented. No this kind of structure is published in
the publications and disclosed before it is applied for a patent
application. So the invention actually has novelty.
[0123] 8. Comparing with the prior flushing lavatory, the invention
has better technical advancement. Its particular structural feature
and function are much advanced and the prior art can't compare with
it. The invention has good technical advancement and practicability
and also has the excellent effect of easy using. Other new
functions are promoted in the invention and it really has the
creativity and practicability.
[0124] Generally, the flushing lavatory with the particular
structure has the above advantages and practical value. It has
innovation on the space structure conformation. Comparing with the
prior flushing lavatory, many new functions have been promoted and
its structure is simple. The invention has big technical progress
and the excellent effect of easy using. It is a new design with
novelty, advancement and practicability and has widely utilizing
value in the industry.
