The invention discloses a multifunctional windscreen wiper water-spraying device, and belongs to the field of automobile windscreen wiper auxiliary devices. According to the device, a positive electrode wire and a negative electrode wire are led out of an automobile storage battery, an ignition switch is connected to the positive electrode wire in series, and a windscreen wiper branch circuit, a water-spraying pump branch circuit and a spraying cooling branch circuit are connected to the part, between the positive electrode wire and the negative electrode wire, behind the ignition switch in parallel. A windscreen wiper switch, a windscreen wiper low-water-level switch and a double throw relay coil loop are connected to the windscreen wiper branch circuit in series. A water-spraying pump (B1) and a normally open contact (C1) in an output loop of a double throw relay (A1) are connected to the water-spraying pump branch circuit in series. An AC switch, a spraying low-water-level switch, a high-water-level switch and a water-spraying pump control module are connected to the spraying cooling branch circuit in series. According to the device, the windscreen wiper water-spraying pump and a water collecting kettle are integrated to achieve the multi-purpose effect, in this way, water can be supplied to a windscreen wiper water-spraying opening and an air conditioner spraying cooling system, then the equipment cost is lowered, and limited in-vehicle installing space is saved.
