Respectively the signal condition figure of the utility model preferred embodiment shown in Figure 11,12.
Shown in Figure 1 is the schematic diagram of the utility model preferred embodiment.The water supply control mechanism 3 of present embodiment is to be installed between toilet 2 and the inlet pipeline 22, it is the user mode that is in stool or urine that the induction installation that is installed in appropriate location on the wall 14 in the water supply control mechanism 3 is used for detecting, after leaving away, the user supplies with discharging quantity of water suitable in the toilet 2 immediately, make the excreta and the clear water of the human body in the toilet 2 flow to septic tank by row's thing mouth 24 of toilet 2 in the lump, to keep health and cleaning.Below do further explanations at water supply control mechanism 3.
Shown in Figure 2 is the three-dimensional exploded view of water supply control mechanism and induction installation.As shown in FIG., be equiped with electromagnetic valve 32 in the casing 31 of water supply control mechanism 3, advance with main members such as water control valve 34, machine plates 36.Shown in Figure 3, be the sectional view of electromagnetic valve, electromagnetic valve 32 includes main members such as housing 320, induction coil 321, permanent magnetism element 322, flexible member 323, Magnetic drive elements 324 and filler block 325.
Shown in Figure 4 is the action schematic diagram of electromagnetic valve.After induction coil 321 obtains driven by power, can produce induction force with magnetic, make Magnetic drive elements 324 be subjected to the effect of Magnetic Induction power, shift to top extruding flexible member 323, make flexible member 323 become the state of compression, when Magnetic drive elements 324 is displaced to the top, can be adsorbed in the bottom surface of permanent magnetism element 322 by the effect of magnetic force, make the filler block 325 unlatching inlet channels 326 of interlock and the water route between the outlet conduit 327, make current be circulated.And, because permanent magnetism element 322 has lasting magneticaction, even stop to supply with induction coil 321 electric power, above-mentioned Magnetic drive elements 324 still can be by the magneticaction of permanent magnetism element 322, make Magnetic drive elements 324 still be adsorbed in the bottom surface of permanent magnetism element 322, continue to keep the unlatching in water route.If when closing the water route, only need send into backward current, rely on to produce rightabout magnetic field induction power, fall and order about Magnetic drive elements 324, and make filler block 325 be stopped the circulation in water route.Therefore, electromagnetic valve 32 only needs when Magnetic drive elements 324 is moved up or down, just provide suitable Magnetic Induction power to drive Magnetic drive elements 324 by induction coil 321, so when Magnetic drive elements 324 is adsorbed in permanent magnetism element 322, need not provide electric power in induction coil 321, so electromagnetic valve 32 has the advantage and the effect of saving electric power.
Consult Fig. 5,6 sectional view as can be known, inlet and outlet control valve 34 has body 340, and body 340 inside are equiped with and can be shifted and the cock body 341 of controlled water flow passage up and down.When electromagnetic valve 32 be subjected to excitatory after, rely on the water and the other end discharge of air in spaces 342 in the pipeline 344 guiding bodies 340, so cock body 341 can be opened water stream channel (shown in Fig. 6 arrow 345) via electromagnetic valve 32.
Fig. 7 is the circuit diagram of the utility model induction installation.Induction installation 4 comprises inductor 40(such as infrared inductor), radiating circuit 41, receiving circuit 42, CPU 43, counter 44, solenoid valve control circuit 45 and battery electric power inspection show members such as circuit 47; CPU 43 has ALU ALU, random access memory ram, unit such as read only memory ROM and input/output port I/OPORT, and in ROM, deposit the program of carrying out flush action of having recorded in advance, the flow chart of program can be illustrated by Fig. 8,9,10, please continue to consult following graphic and explanation.
Shown in Figure 8 is the program flow diagram of main program in the CPU.After the main formula initial (ATSRT), step S01 is that (L=0 K=0), then jumps into (JUMP) first subprogram and (carries out among the A～B) for N=1, C=0 for parameter in the pre-set program.
Shown in Figure 9 is the program flow diagram of first subprogram.Cooperate shown in Fig. 7,8, the step S21 of first subprogram is the power supply that starts the receiving circuit 42 in the induction installation 4, and setup parameter D=3.Step S22 postpones 1 minute (ms), to wait for that receiving circuit 42 reaches stable state.Step S23 starts radiating circuit 41, and drives inductor 40 and launch to the external world and transmit, and to test big chamber pot whether use is arranged, and by inductor 40 signal that receives is input in the receiving circuit 42 more simultaneously.The signal that receiving circuit 42 can receive has two kinds, and a kind of is the long received signal C that is produced when using the state of chamber pot, and another kind is to work as the closely short receptor signal K that produced of TouchSensor 40 of palm.The difference of two kinds of signals is that the strong and weak degree of signal has tangible difference.The long received signal of for example being launched is longer to the distance between the receiving circuit, thus signal numerical value a little less than; And the short receptor signal of being launched is shorter to the distance of receiving circuit, so signal numerical value is stronger.And CPU 43 can initiatively be done identification to received signal degree of strength, determining being long received signal C, or short receptor signal K.Then by step S24 judge " if " (IF) parameters C=1 or (OR) state of K=1.The STA representation that is Yes receives signal, just carries out the loop of D=D-1 with step S25.Transmit if therefore receive, be in the state of continuous generation, received signal is produced continuously just transmit.So transmit as shown in Figure 11 and received signal be in three signals of continuous generation and form the state of a cipher code set.Then under the condition of D=0, close the power supply of supplying with Power Generation Road 41 and receiving circuit 42, make radiating circuit 41 and receiving circuit 42 no longer expend electric power by step S26.Like this, not only can reach the effect of economize on electricity, and for other subsequent step not influence fully.Step S27 is used for having judged whether short receptor signal (just whether K=1), if the state of " nothing " NO, the result who enters step S30 so carries out N=N+1 by step S31 during for "Yes" Yes so, and turns back to and carry out step S02 in the main program.If C=0, it is initial to return main program by step S04 execution sleep 1 second (sleep 1 sec) so.
Consult shown in Figure 8ly, after the step S02 test parameter N of main program and the value of C, if be the state of C=0 through judging, all will be regarded as the unmanned state that uses of big chamber pot, carry out everything all sleep 1 effect by step S04 this moment.Therefore by the state diagram of Figure 11 as can be known, when stage D 1 was not promptly used, two interlude cycles that transmit were 1 sec(1 seconds).If during, just expression has received signal to produce via above-mentioned judgement N＜4 and C=1.For confirm be at this moment through or at the state that uses, postponed for 1 sec(1 second by step S03 in the main program) afterwards, returning among first subprogram A～B circulation again and carrying out next emission and the work that receives.If the scope of people through induction just arranged, and the time is not when surpassing three seconds, so shown in stage D2 among Figure 11, though transmit, but the received signal desire is imperfect and fail more than continuous reception 3 sec, produces so do not have flush signal this moment.Therefore can will there be the state of people's process to get rid of in this way, and can not carry out flush action.
Consult simultaneously shown in Fig. 7,8, when main program step S02 judged N 〉=4 and C=1, expression confirmed to have user (at least three seconds time is shown in D3 among Figure 11).Therefore execution in step S05 stops counter 44, and the counter content is read among the buffer T, and removes counter 44, waits for the follow-up numerical value that reads in.And the content among the buffer T will be subjected to the judgement of step S06, if T≤3 minute are the states of NO, surpass three minutes the blanking time of once time using therewith before the expression so, be carried out the action of preposition bath this moment by second subprogram D～E.
Shown in Figure 10, be the program flow diagram of second subprogram D～E.Cooperate shown in the 7th, 8,9 figure, the S41 of second subprogram starts the electric power inspection and shows circuit 47, detects the electric weight of battery, and the value of detecting is deposited among the buffer P, electric power is examined shown that circuit 47 closes then.Then step S42 tests the value of buffer P, if P=0 represents power shortage so, the driven for emitting lights element (as LED) of step S43 meeting is at this moment informed the external world with the signal of power shortage, so that change battery.And if P=1, step S44 starts electromagnetic valve 32 and continues ON states 40ms(40 minute).By the solenoid valve control circuit 45 of Fig. 7 as can be known, by transistor Q1 by CPU 43 triggering and conducting 40ms(40 minutes) make electromagnetic valve 32 continue ON states 40ms(minute).The contact of relay R 1 forms the conducting loop by normally closed (nc).Therefore the induction coil 321 of electromagnetic valve 32 will be by excitatory and make magnetic drive unit's element 324 upward displacements and be adsorbed on the bottom surface of permanent magnetism element 322.Even therefore 40 fens clock times surpass, electromagnetic valve 32 still can keep water-flowing path to open, and big chamber pot also just is subjected to the clear water flushing.Then get back to main program step S07 among Fig. 8, it plays a part to postpone 2 seconds, and making the time of bath this moment is 2 seconds.Close electromagnetic valve 32 by step S08 again, by electric crystal Q2(such as Fig. 7) closed electromagnetic valve 32 in 40 minutes by CPU 43 triggering and conducting.Relay R 2 jumps to contact often by normally closed (NC) and opens (no) point, therefore R2 normal opened contact (no) forms the conducting loop with R1 normally closed contact (nc), so the induction coil 321 of electromagnetic valve 32 will be by contrary excitatory and make Magnetic drive elements 324 displacement downwards and break away from the bottom surface (Fig. 3 as described above) of permanent magnetism element 322, so electromagnetic valve 32 can cut out the action of bath.By the flush signal of Figure 11 as can be known, after confirming to use, electromagnetic valve 32 produces the time of promptly opening 2 seconds, carries out preposition bath, makes excreta unlikely attached on the big chamber pot.
Look back Fig. 8, after preposition bath action in 2 seconds is finished, main program will be carried out first subprogram A～B again, with the signal of waiting for that the user leaves away.When judging that by step S09 the state of parameters C=0 is set up (path of Yes just), the expression user leaves away.If when the state of parameters C=1, postpone 1 second and rebound front so and carry out first subprogram A～B again and whether leave away with the test user.Under the state that the user leaves away (parameters C=0 just), main program will be jumped among second subprogram D～E and carry out (as shown in figure 10), carry out the follow-up bath that the user leaves away by relay R 1 opens solenoid valve 32, and is 7 seconds (as Figure 11) by step S11 with this follow-up bath time set, drive relay R 2 by step S12 at last and close electromagnetic valve 32, and pick up counting by step S13 enabling counting device 44, and return 1 second state of sleep, return initial (START) of main program, repeat above-mentioned action.S06 judges in step, if T≤3min is the state of Yes, represent last time to use do not have above 3 minute blanking time so with this use, therefore the step S06 of main program will directly jump into first subprogram A～B execution, to save the action of preposition bath, reach the effect of water and electric saving.
Figure 11 is the signal condition figure of preferred embodiment of the present utility model.As transmitting with shown in the received signal among Figure 11, transmitting of present embodiment is a cipher code set.Not having under the situation of using (as the D1 stage), when not having received signal after first yard emission of cipher code set, just second of cipher code set yard no longer emission so.Because first yard state that does not have reception can be confirmed not use.And if the user is arranged through out-of-date (as the D2 stage), though receive one group of complete password received signal, but second group password received signal does not receive fully, or the time did not reach more than three seconds, on behalf of the user, this walked out outside the induction range, does not just have flush signal and produces.If having interfering signal to pass in the receiving circuit 42, the external world produces when receiving (as the D4 stage), though second yard or trigram transmitting and may launch cipher code set because of the generation of interfering signal, the generation that this situation can't be continuous.Because interfering signal and present embodiment transmit and received signal can be not synchronous fully, interfering signal can not make received signal produce the state of cipher code set, but identification interfering signal so transmit, and can continuous emission not have transmitting of cipher code set, and return to first yard state of normal transmission one cipher code set.If generation flush signal, must judge parameter N 〉=4 and C=1 via main program step S02 in the present embodiment, (using time in induction range above three seconds as the D3 stage) confirmed that the user is arranged in expression, after receiving four continuous and complete cipher code set, just carry out two seconds action of preposition bath, and carry out seven seconds action of follow-up bath again in the user back (just parameters C=0 o'clock) of leaving away, to clean the urine in the urine pot fully.If use does not next time reach (shown in the D5 stage among the figure) more than three minutes with the blanking time of this bath, main program will can not carried out preposition flush action so.Because follow-up bath last time and this preposition bath are around, and last time the effect of follow-up bath still made big chamber pot keep moistening state.So last time follow-up bath can replace preposition bath this time, only carries out seven seconds action of follow-up bath after this user leaves away again.Therefore,, just do not have the action of preposition bath, so have the effect of saving water source and electric power so long as do not reach more than three minutes the blanking time that use front and back.
Look back shown in Figure 9ly, and cooperate and to consult Figure 10, when the user with palm closely TouchSensor 40(such as Fig. 7) and when producing short receptor signal K, can cause that step S27 is "Yes" Yes state in first subprogram.Carry out L=L+1 by step S28 again, step S29 judges whether L equals 1.If L=1 just jumps into the flush action (as the flush signal among Figure 12) of carrying out opens solenoid valve among second subprogram D～E.Then judge by step S45 whether L equals 0.After user's palm leaves the induction range of inductor 40, because step S28 causes L ≠ 0 after carrying out,, step S33 continues execution in step S34 down so being the state of " nothings " NO, make the flush signal generation of closing electromagnetic valve.And step S35 is a state of setting L=0.When the user closely during TouchSensor 40, just can produce the effect of bath with palm; And when palm left the scope of inductor 40, flush action was just along with stopping.The purpose of this design is that the excreta in chamber pot can utilize this design to wash by water continuously, to reach the effect that cleans up fully under the state of not rinsing well for auxiliary effect.
