With Figure 19 and 40 is example and with reference to Fig. 2,11,12,21,29 and 30 etc., start hand-held remote controller 31 buttons 33, receiver of remote-control sytem 32 is energized output one unlatching positive pulse, enter bistable circuit 60 the 6th end, bistable circuit 60 outputs are by the hypermutation low level, and signal 92 trailing edges make flow benchmark 54 and 56 export pairing urine or stool benchmark according to excrements sensor 98 high-low levels; Low level signal 92 one tunnel makes solid-state relay 40 or 95 conductings, and dynamoelectric water valve 2 is opened, tap water by water pipe 1, flow transmitter 50, the water valve 2 opened to jet water spout 3 flushing bedpan sidewalls and flow in the bedpan 6; Low level signal 92 another roads make in the counter 51 the RD end enter count status or open triode VT1 make flow transmitter 87 Fig. 6 is seen in electric work; Low level signal 92 one the tunnel enters not gate 65 and is high level output and enters and door 62 again again; Just begin owing to supply water, comparator 57 is output as high level and enters and door 62, with door 62 output high level, makes solid-state relay 41 or 96 conductings, and negtive-pressure implement 5 is started working; Similar aforementioned, the negtive-pressure implement 5 of energising is set up negative pressure between two traps, and negative pressure makes a small amount of clear water that pours replace mixing materials in the bedpan 6 and reaches the purpose of water saving; The displacement of water in bedpan 6 finishes, and when comprising the numerical value that the numerical value of the flow transmitter 87 of sensor 50 and counter 51 functions sets greater than negtive-pressure implement flow benchmark 56, comparator 57 output low levels with door 62 output low levels, are turn-offed negtive-pressure implement 5; After the water seal moisturizing finishes, during numerical value that the numerical value of flow transmitter 87 is set greater than water valve flow benchmark 54, the 2nd end that comparator 55 output low levels enter bistable circuit 60 makes it to export high level, high level signal 92 one tunnel enters solid-state relay 40 or 95 makes it turn-off water valve 2, high level signal 92 another roads enter flow transmitter 87 makes it to enter zero clearing or off-position, high level signal 92 again one the tunnel through not gate 65 make with the door 62 output low levels; A circulation is finished.

With reference to Figure 11,12,19,30 and 40, when low, the actual water supply flow of hydraulic pressure of tap water during less than the dynamic flow benchmark set, also be provided with in the power control box 16 control in using negtive-pressure implement 5 operations and or the adaptive circuit 69 of standstill state, by dynamic flow reference circuit 88, comparator 89, pulse generation and sampling hold circuit 90 are formed; Wherein, flow transmitter 87 and 88 outputs of dynamic flow reference circuit connect comparator 89 respectively, and comparator 89 outputs connect pulse generation and sampling hold circuit 90; In pulse generation and the sampling hold circuit 90 output connection control circuits 86 with door 62 or 83; Control circuit 86 and pulse generation and sampling hold circuit 90 outputs connect dynamic flow reference circuit 88 respectively.Then above-mentioned, supplying water has just begun to be high level as sampling hold circuit 61 output Q ends, and comparator 57 is also exported high level, and with door 62 output high level, solid-state relay 41 or 96 conductings, negtive-pressure implement 5 is started working; Sampling hold circuit 61 inversion signals 85 make its conducting for low level enters electronic switch 53 Enable Pin EN, or sampling hold circuit 61 output Q ends make its conducting for high level enters electronic switch S1 control end, the pulse signal of basic pulse generator 59 enters counter 52 countings through the electronic switch 53 or the S1 of conducting, subsequently sometime when counter 52 numerical value during greater than counter 51 or flow transmitter 87 numerical value, comparator 58 output low levels, when impulse generator 63 or 66 produces a rising edge, sampling hold circuit 61 output Q end outputs one low level is through turn-offing negtive-pressure implement 5 with door 62 and power amplifier level; Simultaneously, sampling hold circuit 61 output Q end low levels make electronic switch S1 or signal 85 high level enter that the EN end opens circuit switch or high resistant in the electronic switch 53, counter 52 stops counting, forereach gradually up to counter 51, make comparator 58 output high level, and produce a rising edge again when impulse generator 63 or 66, circuit 61 output Q ends transfer high level to, with door 62 output high level, negtive-pressure implement 5 is started working again, circuit 61 just or reversed-phase output electronic switch S1 or 53 is connected again, counter 52 can continue series reaction such as counting again, so-called dynamic flow reference circuit 88 is meant accumulated value adjustment automatically along with actual current of this benchmark, thereby makes native system that the adaptation control ability be arranged; Be after water valve 2 is opened, the low discharge tap water flows to bedpan 6, negtive-pressure implement 5 is started working, siphon away the most mixing materials in the bedpan 6, because actual water supply flow is little, adaptive circuit 69 temporarily turn-offs negtive-pressure implement 5 or makes it not produce the suction low cruise, up to low discharge supply water continue to enter run up in the bedpan 6 a certain amount of after, negtive-pressure implement 5 is started by the cycle again, siphon away the most clear water and the mixing material that just pour in the bedpan 6, and so forth, greater than flow benchmark 56 numerical value, turn-off negtive-pressure implement 5 until the numerical value of flow transmitter 87; After the water seal moisturizing, the numerical value of flow transmitter 87 turn-offs 2, one circulations of water valve and finishes during greater than flow benchmark 54 numerical value.

The intervention of adaptive circuit 69 makes negtive-pressure implement 5 in the normal operation or in using produce the pause in cycles or low cruise and controls its running status in using when hydraulic pressure is low, and is few as can not to play the hermetic seal effect and the also long-time running of negtive-pressure implement 5 is bled and consequent noise to avoid liquid in the bedpan 6; Capacitor C 7 act as bistable circuit 60 each electric or have a power failure after when recovering energising again, controlled load is in off-position, current-limiting resistance R7 resistance value is much smaller than R39, resistance R 38 is anti-parasitic capacitance effect; The RD end that dotted line signal 92 also can connect sampling hold circuit 61 among Figure 11 removes not gate 65 simultaneously and sees Figure 19; Because bistable circuit 138 has just anti-phase output respectively, the function that can cover bistable circuit 60 is removed not gate 65 simultaneously and is seen Figure 21, makes circuit come more simply by the combination of bistable circuit 138 and data selector 141.Caliber 12 and or 121 should have certain volume, in case mixing material enters the negtive-pressure implement 5 in the use.Second trap 18 or 28 advantage are to connect the moment that caliber 12 negative pressure disappear, second trap produces stronger siphon sometimes, cause this trap to run off the due water yield and may influence its usability subsequently, trap 18 or 28 can slacken the effect of this siphon than trap 8, and second trap 18 or bigger being beneficial to of 28 water capacities adapt to control when water seal height is identical.Even if hydraulic pressure hangs down occasion, said apparatus has reached button excrements and has discerned the adaptation bath automatically, can more reasonable water saving on the basis of rinsing well.

It is digital to see that Fig. 5,11,12 and 20 etc. is similar to, when analogue flow rate sensor 70 or flow transmitter 87 are output as voltage signal, 98 outputs of excrements sensor connect the control end of two electronic switch S2, S3, if sensor 98 output high level during stool, electronic switch S2, S3 are respectively with resistance R 52, R53 short circuit, reference potential device R18 and R19 voltage raise, and are the stool basic parameter, otherwise are the urine parameter; For big or urine, following operating principle and circulate identical.Starting switch 67, export a pulse, through nor gate 74, the anti-CP end that starts electrical noise shaping pulse monostable 76, enters bistable circuit 75, bistable circuit 75 output high level, enter power amplifier level R27, VT4 and relay K 1 and make its conducting, contact K1-1 closure, solid-state relay 40 conductings, dynamoelectric water valve 2 is opened, and tap water pours in the bedpan 6 through flow transmitter 87 to jet water spout 3; Contact K1-2 closure, solid-state relay 41 will be looked triode VT5 conducting and conducting; Contact K1-3, K1-4 closure, circuit 71,72,78,79 are connected the both positive and negative polarity of power supply respectively and are entered user mode, and R8 and C8, R9 and C9 are for suppressing circuit noise; Just begin owing to supply water, sensor 87 output voltages are less than potentiometer R19 output voltage, and comparator 77 outputs one high level signal 93 makes solid-state relay 41 conductings through resistance R 28 and triode VT5, and negtive-pressure implement 5 is started working; When the hydraulic pressure of tap water substantially just often, the negtive-pressure implement 5 of energising is set up negative pressure asking of two traps, washes out the interior liquid of bedpan 6 and reaches the purpose of water saving with less clear water; It is roughly the same aforementioned that subsequent working state such as negtive-pressure implement 5 and dynamoelectric water valve 2 are turned off etc. according to this.

When the hydraulic pressure of tap water is lower than normal value, the introducing of adaptive circuit 69 is interrupted negtive-pressure implement 5 cycle of generation in use, then above-mentioned, as certain moment sampling hold circuit 82 is output as high level after starting, in the time of negtive-pressure implement 5 work, the almost full power supply signal 94 of high level enters adjuster 78 and dwindles, enter integrator 79 again after simulating the normal current signal of telecommunication, integrator 79 outputs enter comparator 80, when certain moment, integrator 79 (or dynamic flow reference circuit 88) output voltage was greater than integrator 72 (or flow transmitter 87) output voltage, comparator 80 (or comparator 89) output low level, when circuit 81 produces a rising edge, sampling back circuit 82 output low levels are through turn-offing negtive-pressure implement 5 with door 83 and power amplifier level; Signal 94 is a low level, and integrator 79 integrated values no longer rise, and catch up with and produces a rising edge again, makes circuit 82 output Q end transfer that high level, negtive-pressure implement 5 are started working again, integrator 79 integrated values rise to again again when impulse generator 81 up to integrator 72; And so forth, during greater than potentiometer R19 reference voltage, comparator 77 output low levels are turn-offed negtive-pressure implement 5 up to sensor 87 output voltages; After the water seal moisturizing, sensor 87 output voltages are during greater than potentiometer R18 reference voltage, comparator 73 outputs one high level, through nor gate 74, monostable circuit 76, bistable circuit 75 and triode VT4 relay K 1 is turn-offed, contact K1-1, K1-2, K1-3 and K1-4 all disconnect, turn-off water valve 2 and interlock circuit, a circulation is finished; Capacitor C 17 suppresses circuit noises, R12 and C12 make bistable circuit 75 connect electricity initial or have a power failure after when recovering energising again, controlled load is in off-position; Roughly the same aforementioned this adaptation control scheme can be widely used in general occasion.
