Fig. 1 is the circuit diagram of timing router.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, in the utility model embodiment, a kind of timing router, comprises chip U1, resistance R1, potentiometer RP1, diode D1, relay J, diode D3, electric capacity C1 and switch S, described switch S one end connects 220V alternating current one end, and the 220V alternating current other end connects electric capacity C1 respectively, chip U1 pin 1, electric capacity C2, relay J coil, diode D3 positive pole, resistance R5 and router, the described switch S other end connects electric capacity C5 respectively, resistance R4 and relay J contact J-1, the relay J contact J-1 other end connection route device other end, the described resistance R4 other end connects the electric capacity C5 other end respectively, diode D4 positive pole and diode D5 negative pole, diode D5 positive pole is the contact resistance R5 other end respectively, diode D6 positive pole, electric capacity C4 and electric capacity C3, diode D6 negative pole connects diode D4 negative pole respectively, the electric capacity C4 other end and resistance R3, the resistance R3 other end connects the electric capacity C3 other end respectively, chip U1 pin 4, chip U1 pin 8 and resistance R1, the resistance R1 other end connects potentiometer RP1 respectively, potentiometer RP1 slide plate, diode D1 positive pole and chip U1 pin 7, potentiometer RP1 other end contact resistance R2, the resistance R2 other end connects the electric capacity C1 other end respectively, diode D1 negative pole, chip U1 pin 2 and chip U1 pin 6, chip U1 pin 5 connect the electric capacity C2 other end, and chip U1 pin 3 connects relay J coil and diode D3 negative pole respectively.

Chip U1 model is NE555.

Operation principle of the present utility model is: refer to Fig. 1, chip U1 and potentiometer RP1, resistance R1, resistance R2, diode D1, diode D2 and electric capacity C1 etc. constitute an astable circuit, and electric capacity C5 and resistance R4 (discharge resistance of C5), diode D4, diode D5, diode D6, resistance R3, electric capacity C3, electric capacity C4 form D.C. regulated power supply.The course of work of circuit is as follows:

When after the S that closes a switch, 220V alternating current provides a comparatively galvanic current pressure to chip U1 after electric capacity C5 and resistance R4 (discharge resistance of C5) step-down and diode D4, diode D5 rectification and diode D6, resistance R3, electric capacity C3, electric capacity C4 voltage regulation filtering.When just closing S, the voltage because of electric capacity C1 two ends is zero and can not suddenlys change, and now 2,6 pin of chip U1 are low level, and 3 pin export high level, and relay J adhesive, router obtains electric starting working.

Meanwhile, 3 pin because of chip U1 are high level, therefore its 7 pin is also high level, diode D1 conducting, D2 cut-off, power supply is charged to electric capacity C1 by RP1 and resistance R1, charging rate is adjusted by potentiometer RP1, when the voltage on electric capacity C1 is charged to 2/3 supply voltage, 2,6 pin of chip U1 become high level, and 3 pin are corresponding becomes low level, relay J discharges, and router quits work.Because 3 pin of chip U1 become low level, therefore 7 pin also will become low level, and diode D1 ends, D2 conducting, and electric capacity C1 is discharged by resistance R2, and the velocity of discharge is adjusted by RP1.When voltage on electric capacity C1 reduces to 1/3 supply voltage, 2,6 pin of chip U1 become low level again, and whole circuit will repeat the above-mentioned course of work again.
