Description

[0001] The present invention relates to a double spray nozzle device for a vehicle,

The present invention relates to a double spray nozzle apparatus for spraying a fluid such as a washer liquid to a windshield glass of an automobile.

Generally, the automobile is provided with a washer liquid injection system for supplying washer liquid to the windshield glass. In the washer fluid injection system, a fluidic type spray nozzle for discharging a fluid (washer fluid) supplied through a flow path to the outside is formed.

The conventional fluid type spray nozzle performs a spray function of spraying the fluid supplied through the flow path to the outside, and when operating under the basic condition (normal temperature condition), the fluid spreads in a spray mode and is sprayed to the windshield glass as a whole .

However, such conventional spray nozzles are problematic in that when the spray nozzle operates at a low temperature, the washer fluid is injected narrowly in a straight shape without being sprayed broadly due to a drop in function of the spray nozzle.

In order to solve the problem of the conventional spray nozzle, a nozzle having a double spray function has been used. However, this has a problem in that a cost increase is caused due to a structure for spraying the washer liquid.

SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned problems, and it is an object of the present invention to provide a spray gun capable of evenly spraying a fluid on a front surface of a windshield glass by using a main chip for generating a spray flow and an auxiliary chip for jet generation, The present invention is directed to a double spray nozzle apparatus for an automobile.
