Multifunctional windscreen wiper water-spraying device

Abstract

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.

Description

technical field [0001] The invention relates to an auxiliary device for an automobile wiper, in particular to a multifunctional water spray device for a wiper. Background technique [0002] At present, because the wiper sprinkler is often used in driving, the front and rear windshields are cleaned when spraying water. The sprinkler is only used to pressurize the water spray nozzle of the wiper, and the wiper sprinkler is also used for a single purpose. It is used for the water storage of the wiper; when the heat dissipation of the air conditioner is not good and the cooling is not good, it is necessary to spray cold water on the high pressure pipe of the heat dissipation network of the air conditioner to cool down, so that the cooling is faster, more comfortable, and also Need cold water storage device and water spray pump device, like this, will adorn two cover water storage and water spray device on the car, increase production cost, take limited space in the car.

[0002] At present, because the wiper sprinkler is often used in driving, the front and rear windshields are cleaned when spraying water. The sprinkler is only used to pressurize the water spray nozzle of the wiper, and the wiper sprinkler is also used for a single purpose. It is used for the water storage of the wiper; when the heat dissipation of the air conditioner is not good and the cooling is not good, it is necessary to spray cold water on the high-pressure pipe of the heat dissipation network of the air conditioner to cool down, so that the cooling is faster, more comfortable, and also A cold water storage device and a water spray pump device are required. In this way, two sets of water storage and water spray devices will be installed on the car, which will increase production costs and occupy limited space in the car.
