Zusammenfassung: | The invention provides a wiper intermittent controller, which comprises a wiper motor and a washing motor. The wiper intermittent controller is characterized in that: the wiper mainly comprises an initial position precise timing circuit and an accurate time delay discharge circuit; the initial position precise timing circuit comprises a third resistor, a fourth resistor, a first capacitor, an eighth resistor and a fourth Darlington block; and the accurate time delay discharge circuit comprises a ninth resistor, a third Darlington block, a second diode and a second capacitor. The wiper solves the problems of low working current and poor reliability of the conventional wiper, inaccurate time delay, great external influence, short service life and disadvantage for the service life of the wiper motor. The controller has a compact and reasonable structure and obvious effect, and is favorable for popularization and application. |
