The not moved end s of master cock K and power Vcc are anodal to be connected, master cock K first not moved end 1 be connected with washing motor M1, master cock K second not moved end 2 be connected with the time-delay end 1 ' of 555 chip IC of intermittent control circuit A.The negative pole of three first diode D1 all is connected with the emitter of the second aerotron TP1, the positive pole of three first diode D1 respectively with master cock K first not moved end 1, master cock K second moved end 2 and rain shaving electrical machine M1 are not connected.
Below in conjunction with Fig. 2 the principle of work of the utility model is done a detailed explanation.
In initial condition following time, master cock K is in and closes shelves, and three first diode D1 provide working power all can not for the second aerotron TP1; At this moment; Because the emitter of the second aerotron TP1 does not have working power, even the first triode TN1, second resistance R 2, the 3rd resistance R 3, the 4th resistance R 4 produce coupled voltages because of receiving electromagnetic interference, the second aerotron TP1 can not cause unexpected conducting yet; Thereby make Wiper Relay J adhesive, and then cause rain shaving electrical machine M2 misoperation.
When master cock K is in intermittently shelves; Power supply is given the power supply of 555 chip IC; Trigger 555 chip IC and produce the rule square wave; Square wave makes intermittently conducting of the second aerotron TP1 through second resistance R 2 and the first aerotron TN1, thus intermittently adhesive of second aerotron TP1 control Wiper Relay J, and then control rain shaving electrical machine M2 intermittent use.
When master cock K was in the water spray shelves, power Vcc made the first aerotron TN1 conducting through the second diode D2 and the 3rd diode D3, and power Vcc provides working power for the second aerotron TP1 through one of them first diode D1; Thereby make the second aerotron TP1 conducting; Like this, second aerotron TP1 control Wiper Relay J adhesive, rain shaving electrical machine M2 continuous firing; Simultaneously, power Vcc is charged to capacitor C through the second diode D2.In addition, power Vcc is supplied power to washing motor M1, makes washing motor M1 water spray.After water spray finishes; Master cock K gets back to automatically and closes shelves, the second diode D2 anode loss of voltage, at this moment; Capacitor C begins discharge makes the first aerotron TN1 and the second aerotron TP1 continue conducting; And the working power of the second aerotron TP1 by be connected master cock K first or not diode D1 of moved end 1 switch to and the rain shaving electrical machine M2 bonded assembly first diode D1, thereby rain shaving electrical machine M2 is worked on, to remove residual cleansing fluid on the air regulator.Behind the capacitor C discharge off, the first aerotron TN1 and the second aerotron TP1 break off, and Wiper Relay J also breaks off, and rain shaving electrical machine quits work, and with the rain shaving electrical machine M2 bonded assembly first diode D1 on also automatic cutout of power supply.
Can know by technique scheme; Because when the moved end s of master cock K and being in when two moved end 1,2 does not all connect closed grade, two input ends of the intermittent control circuit A of the utility model all were not connected with power Vcc; Thereby; Even the end instr among the intermittent control circuit A produces coupled voltages because of electromagnetic interference, the mouth of intermittent control circuit A can not produce drive current yet and make Wiper Relay J adhesive and cause rain shaving electrical machine M2 misoperation, thereby plays jamproof effect.In addition; Satisfying under the jamproof prerequisite; Through being connected three first diode D1 on one of them input end of intermittent control circuit A, can also guarantee that the utility model is in when closing grade, still has delay function after water spray finishes; Rain shaving electrical machine M2 is worked on, to remove the raffinate on the air regulator.
