Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning technique for an automobile headlamp cleaner that jets out washing water for washing the headlights of a car while the car is running, and is directed to a multiple jetting method for a headlamp cleaner. It concerns the nozzle.

[Conventional technology]

Conventionally, headlamp cleaners have been used to clean mud, insects, etc. that adhere to the front of a car's headlamp while driving, and restore the headlamp's light emitting performance.It has a structure that sprays high-pressure cleaning water from a nozzle toward the headlamp surface. are used.

[Problem that the invention seeks to solve]

However, this type of headlamp cleaner removes dirt by simply spraying cleaning water, so if dead insects or other insects are attached and dry, it will not be able to remove these dirt. There is a problem in that the adhesive becomes dry and stuck again in a short period of time when the car is driven. In addition, in recent years, headlamps have become a part of car design, and so-called proper headlamps, which have different lens shapes for each car, have become mainstream. Wide headlights are becoming more common. For this reason, the cleaning water that diffuses and jets out from the headlamp cleaner does not reach the entire headlamp surface, leaving some residue behind.However, if the entire headlamp could be rinsed away, it would scatter around the headlamp without hitting the headlamp. This causes problems such as an increase in the amount of cleaning water used, a decrease in cleaning efficiency, and a difference in cleaning between the center and the outer periphery.

The present invention was devised in view of the above-mentioned problems.The present invention controls the spray shape so that the sprayed cleaning water is diffused over a super wide angle over the rectangular cleaning surface of the headlamp, and also reliably removes dirt and removes any unwashed water. To provide a redundant injection nozzle for a headlamp cleaner, which uniformly cleans the entire surface of a headlamp by effectively utilizing a limited amount of cleaning water without causing any water loss.

[Means for solving problems]

That is, the overlapping injection nozzle for a headlamp cleaner according to the present invention is used in a headlamp cleaner for a substantially rectangular lens that sprays high-pressure washing water onto the headlamp of an automobile to recover the light emitting efficiency, and each has a different washing water injection pattern. A plurality of cleaning water injection nozzles each having a cleaning water injection port are provided so that each cleaning water injection pattern overlaps, and a cleaning water passageway of a separate system is connected to each cleaning water injection nozzle, so that each cleaning water injection The gist is that the cleaning water is jetted from the nozzle at an appropriate time lag.

[Effect]

Therefore, for example, when two cleaning water injection nozzles are provided, the injection pattern and injection pressure of the side to be injected first are set so as to moisten the entire surface to be cleaned by the headlamp, and the injection pattern and injection pressure of the side to be injected next A dedicated cleaning injection port is established for each cleaning water injection nozzle so that the injection pressure is such that the dirt that has loosened in the previous process and has become fluid on the surface to be cleaned is peeled off and scattered. The multi-stage jetting of cleaning water ensures that dirt is removed.

This effect is the same even when three cleaning water injection nozzles are provided, for example, and in this case, if the surface to be cleaned is an ultra-wide angle type, multiple spray patterns can be sprayed overlappingly, so the overall It is easy to make the spray pattern similar to the surface to be cleaned, and there is no possibility of leaving any residue after washing.

〔Example〕

Hereinafter, embodiments of the dual injection nozzle for a headlamp cleaner according to the present invention will be described with reference to the drawings.
This figure shows a first embodiment in which two parts are provided.

In the drawing, 1 and 2 are cleaning water injection nozzles arranged in parallel on the top of the nozzle case 3, and each nozzle 1, 2 is connected to a cleaning water injection port 4, 5 opened on the front side.
As shown in FIG. 2, independent wash water flow passages 6 and 7 are communicated with each other, and each communicates with a wash water supply source via a wash water supply mechanism (not shown). Each of the above-mentioned cleaning water injection ports 4 and 5 has a third
The upper edge 8, the lower edge 9, and both side edges 10, 10 form a spray pattern 51, 52 on the surface to be cleaned of the headlamp 50 as shown in FIGS. First, after the first nozzle 1 jets out cleaning water for a certain period of time, the second nozzle 2 jets out cleaning water for a certain period of time, either immediately or at certain time intervals.
Therefore, when cleaning water is first jetted from the first nozzle 1 for a certain period of time, the jetting pattern 51 shown in FIG.
The head lamp 5 was
0 The entire surface to be cleaned is moistened to loosen the adhesion of dirt, and the dirt that has become fluid on the surface to be cleaned is then jetted from the second nozzle 2 for a certain period of time as shown in the spray pattern 52 in FIG. 4. With the washing water,
Peel and scatter.

5 to 7 show another embodiment in which three cleaning water injection nozzles are provided.

Three cleaning water injection nozzles 1a, 2, and 1b are arranged in parallel on the top of the nozzle case 3, and each nozzle 1
Cleaning water injection port 4 opened on the front of a, 2, 1b
a, 5, and 4b are configured to communicate with a cleaning water supply source and a cleaning water supply mechanism (not shown) via cleaning water flow passages 6 and 7, respectively. Each of the above cleaning water injection ports 4
a, 4b, and 5 have shapes that form spray patterns 53a, 53b, and 54 on the surface to be cleaned of the headlamp 50, respectively, as shown in FIGS. 6 and 7, and when the cleaning operation is performed, both sides are first After the cleaning water is jetted out from the nozzles 1a and 1b for a certain period of time, the cleaning water is jetted out from the central nozzle 2 for a certain period of time immediately or at certain time intervals.

Therefore, when cleaning water is first jetted from the nozzles 1a and 1b on both sides for a certain period of time, the jetted cleaning water moistens the entire surface to be cleaned of the headlamp 50 as shown in the jetting pattern 53 in FIG. At the same time, the fluidized dirt on the surface to be cleaned is washed away by the cleaning water jetted from the central nozzle 2 for a certain period of time as shown in the jet pattern 54 of FIG. 7.

The method of cleaning a headlamp according to the present invention includes spraying that moistens the entire surface of the headlamp to be cleaned, and spraying that removes and scatters dirt that has loosened in the previous process and has become fluid on the surface to be cleaned. It cleans dirt in multiple stages, thereby ensuring the ability to clean the dirt that has adhered to it.

〔Effect of the invention〕

Since the overlapping injection nozzle for a headlamp cleaner according to the present invention is configured as described above, the dirt adhering to the surface to be cleaned of the headlamp is cleaned in multiple stages, thereby reliably cleaning the dirt, and the overlapping injection pattern Since the cleaning water is sprayed onto the surface to be cleaned in just the right amount, it has excellent features such as not leaving any residue after washing even in a thin and wide headlamp.
