The invention discloses an automobile wiper having a time delay function. The automobile wiper comprises a wiper motor, a wiper supporting connecting rod and a wiper rack; a time delay relay is arranged on the wiper motor, and comprises a resistor R1, a resistor R2, a resistor R3, a capacitor C1, a diode D1 and a field effect tube T1; the resistor R1, the diode D1, the first capacitor C1 and the resistor R3 are orderly connected in series to form the differential circuit of the time relay circuit; the field effect tube T1 and the resistor R1 are connected in series into the switching circuit of the time relay circuit; the resistor R2 is connected with the capacitor C1 into the discharge circuit of the time relay circuit; according to the novel wiper, the time delay relay is arranged on the wiper motor; in use, firstly, a water pump pumps water to a water pipe to wet the automobile windshield; after the water is sprayed by the preset time of 0.5-2 seconds, the wiper functions in wiping conveniently; besides, a clean wiping effect of the wiper can be achieved even under the condition of too much contamination or the wiper can be prevented from being damaged due to large friction.
