Description

Car window washer nozzle to spraying in structure}

The present invention relates to a window washer nozzle having a structure capable of spraying washer liquid evenly on the entire outer surface of the windshield glass of the vehicle, and particularly, uniformly sprayed on the entire outer surface of the windshield glass in an optimal state with the minimum amount of washer liquid required. The present invention relates to a vehicle window washer nozzle with a spray structure that can maximize the cleaning efficiency of the glass and at the same time minimize the washer fluid consumption to reduce washer fluid maintenance costs and enable long-term use without clogging the spray hole by foreign substances.

In general, various vehicles are configured using a transparent glass or the like as much as possible in order to allow the driver to easily identify the road conditions and external obstacles when driving. The most important part of the dual drive is the glass provided in front of the driver. Therefore, the windshield glass in front of the rain or foreign matters will cause trouble in driving and increase the risk of traffic accidents, a means for easily removing rainwater, snow or other foreign objects, which are obstacles to securing visibility, was required. .

Therefore, a representative of such a device is a windshield wiper device, which includes a pair of wiper arms that reciprocate at an angle by a drive motor, and is fixed to the wiper arm so as to be in close contact with the glass outer surface. It consists of a pair of blades, which, if necessary, are operated by the operator's selection to clean the outer surface of the windshield glass. On the other hand, it is mandatory in addition to such a wiper device, if the degree of contamination of the outer surface of the windshield glass is severe or if the cleaning effect is weak only by the wiper operation, water or washing-only washer liquid can be sprayed on the outer surface of the windshield glass. Washer liquid injector is also provided. Here, the washer liquid is a liquid detergent in which an appropriate amount of a surfactant, an antifreeze agent, an organic substance decomposer, a dye, and the like are mixed with the filtered constant.

Such a washer fluid injector is usually provided with a washer nozzle having one or two injection holes which are installed in a bonnet (hood) of a vehicle and spray the set portion of the outer surface of the windshield glass.

As described above, the conventional washer liquid injector is briefly described with reference to FIGS. 6 to 7 as follows.

6 and 7, reference numeral 1 denotes a storage tank, 2 denotes a washer nozzle, 3 denotes a windshield glass, 4 denotes a wiper blade, 5 denotes a nut, and B denotes a bonnet.

The washer fluid storage tank 1 is installed in the engine room of the bonnet B, and a pump motor 1A is provided at one side of the storage tank 1 to pump the washer fluid contained in the storage tank 1.

Then, the washer liquid pumped by the pump motor 1A is windshield glass 3 through the injection hole 2a of the set of washer nozzles 2 fixed to the bonnet B through the supply hose 1B. It is sprayed toward the outer surface, and the washer liquid is sprayed on the upper side of the glass with one or two stems and flows down to the lower part, and then the wiper blade 4 is pivoted to increase the outer surface cleaning efficiency of the glass.

In addition, the washer nozzle (2) has a spiral portion (2b) is formed on the outer surface of the center, and extends directly downwards, the locking jaw (2d) of a predetermined shape formed at the lower end is inserted through the insertion hole of the bonnet 200 is separated It is fastened and fixed by the nut (5) of the lower end is formed to spray the washer liquid supplied through the connection hose (1B).

Here, the washer nozzle 2 has a head portion 2A formed by finely penetrating a plurality of injection holes 2a alone or a pair of upper one side surfaces, and an outer surface at the center of the lower surface of the head portion 2A. A middle portion 2B having a spiral portion 2b formed therein and a hollow supply passage 2c connected to the injection hole 2a, and a diameter at a lower end portion of the intermediate extension portion 2B. It is composed of a hose connection portion 2C which is formed while being extended while being reduced and the end of the connection hose 1B to which the washer fluid is supplied is fitted and the locking jaw 2d is inclined to be firmly coupled.

However, the washer nozzle with the conventional injection hole is, firstly, because the washer liquid is injected directly through the injection hole only at the set injection point of the outer surface of the windshield glass, the injection amount is large and the injection range is narrow, and the glass cleaning efficiency is weak. Since one or two washers of liquid are sprayed at a time, the residual amount of the inclined glass surface is minimal and the remaining washer liquid is removed while the sprayed washer liquid is not able to perform its function, and the driver repeatedly sprays a large amount of washer liquid several times. Therefore, as the consumption of washer fluid increases, the maintenance cost increases due to frequent washer fluid replenishment. Third, the defect of losing the ability to spray the washer fluid due to the blocking of relatively small injection holes due to various fine contaminants and long-term use. Fourth, the driver when a large amount of washer fluid is sprayed momentarily There are shortcomings in the field fleeting safe driving increases the risk that they could interfere with falling, such as marketability and credibility problems for the product.

Therefore, the present invention has been devised to solve the fundamental problems of the prior art, and its object is to maximize the cleaning efficiency of the glass by uniformly spraying the entire outer surface of the windshield glass in an optimal state with the minimum amount of wash liquid required. At the same time, it minimizes the consumption of washer fluid and reduces the cost of washer fluid and enables long-term use without clogging the spray hole due to foreign substances. It is to provide a vehicle window washer nozzle with a spray structure that can form a variety of designed sculptures to increase the productability and reliability, durability, washer fluid reduction and cleaning efficiency of the product.
