Description

[Detailed explanation of the idea] The present invention relates to a headlamp cleaner for automobiles.

Specifically, safety and design are improved by preventing the nozzle body held in the nozzle case attached to the car body from protruding beyond the nozzle case surface, and the jetting performance of the cleaning water is impaired even in cold regions. It is an object of the present invention to provide a novel headlamp cleaner for automobiles that is free from the occurrence of waste.

FIG. 1 shows an example of a conventional automobile headlamp cleaner.

Reference numeral a designates a nozzle case that is attached to a vehicle body, such as a bumper b, and is made of, for example, synthetic resin, and has a holding recess C that is open on its upper surface.

A nozzle holder d is fitted and held in the holding recess C, and has a substantially short cylindrical shape.

e is a cleaning water injection nozzle body held in a holder d so that its angle can be adjusted, and the part g where the injection port f is located is the nozzle case a.
It is protruded from.

In the conventional headlamp cleaner shown in FIG. 1, since a part g of the nozzle body e protrudes from the nozzle case a, external objects may collide with this part and cause damage. Alternatively, the nozzle body e may move relative to the holder d, resulting in a disadvantage that the spraying angle of the cleaning water, which has been carefully adjusted, becomes incorrect.

Therefore, an improvement as shown in FIG. 2 can be considered.

In this headlamp cleaner h, the nozzle holding recess j of the nozzle holder i is made deep so that the cleaning water injection nozzle body k is completely hidden within the holding recess j.

By doing this, there is no possibility that the nozzle body k will be damaged due to collision with an outside object or that the direction of jetting of cleaning water will be changed, and the shape of the nozzle case can be adjusted to match the vehicle body line. This is advantageous in terms of design.

However, since such a headlamp cleaner is used in a state where it is exposed outside the vehicle body, it is impossible to prevent rainwater from accumulating in the holding recess j.

Then, there is a problem that the injection port 1 of the nozzle body is submerged in the accumulated water, and if the accumulated water in the recess j freezes in a cold region or the like, it becomes impossible to spray the cleaning water.

Therefore, the present invention improves safety and design by preventing the nozzle body held by the nozzle case attached to the automobile body from protruding from the surface of the nozzle case, and
The purpose is to provide a new headlamp cleaner for automobiles that does not impair the jetting performance of cleaning water even in cold regions, and is made of appropriate materials such as synthetic resin and hard rubber, and has a means for attaching it to the automobile body. and a cleaning water jet nozzle body held in a recess formed on the upper surface side of the nozzle case. A water drain passage is formed extending from a position below the position of the cleaning water injection port of the cleaning water injection nozzle body and opening to the outside of the nozzle case below the position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the automotive headlamp cleaner of the present invention will be explained below according to the illustrated embodiments.

FIGS. 3 and 4 show an example of the implementation of the automotive headlamp cleaner of the present invention.

Reference numeral 1 denotes a nozzle case that is attached to a part of the vehicle body, for example, a bumper 2, and is made of a suitable material such as hard rubber or synthetic resin.

The upper surface 3 of the nozzle case 1 is slightly inclined, and a substantially cylindrical holding recess 4 that opens in the upper surface 3 is formed.

Reference numeral 5 denotes a water drain passage whose one end opens at the lower surface of the nozzle case 1, and whose inner end communicates with the side of the holding recess 4.

Reference numeral 6 denotes a connecting pipe that is integrally hung from the lower surface of the nozzle case 1, and has a through hole 7 that communicates with the bottom of the holding recess 4.

Reference numeral 8 designates a mounting bolt whose base is embedded in the bottom of the nozzle case 1 and whose tip protrudes from the bottom of the nozzle case 1.

The base of the mounting bolt 8 is fixed.

Thus, this nozzle case 1 is mounted on the bumper 2 by inserting the mounting bolt 8 into the hole 10 formed in the bumper 2, and tightening an appropriate nut to the tip of the bolt 8 protruding from the bottom of the bumper 2. It is set to be fixed.

11 is a nozzle holder made of hard synthetic resin;
It has an approximately cylindrical shape.

The lower end of the nozzle holder 11 has a protruding edge 1 projecting inward.
2 is formed.

Further, this nozzle holder 11 is formed with a notch 13 extending from the upper end to the middle.

This nozzle holder 11 is press-fitted into the holding recess 4 of the nozzle case 1, and at this time, the position of the notch 13 is aligned with the inner end of the water drain passage 5 of the nozzle case 1.

Reference numeral 14 denotes a cleaning water spray nozzle body supported within the nozzle holder 11 so that its angle can be adjusted.

In the nozzle body 14, the holding part 15 and the injection part 16 are integrally formed of synthetic resin.

The holding portion 15 has a spherical outer peripheral surface, and its outer diameter is formed to be approximately the same as the inner diameter of the nozzle holder 11.

Therefore, this holding portion 15 is press-fitted into the nozzle holder 11 until it abuts against the protruding edge 12, so that the nozzle body 14 is held within the nozzle holder 11 and the angle thereof can be adjusted.

A cleaning water injection port 17 is formed in the injection portion 16, and although not shown, the injection port 17 communicates with a passage that opens at the bottom surface of the holding portion 15.

When the nozzle body 14 is press-fitted into the nozzle holder 11, the lower end of the notch 13 is positioned below the cleaning water injection port 17.

In the headlamp cleaner described above, cleaning water is supplied to the through hole 7 of the connecting pipe 6 by a pump (not shown).
and enters the nozzle body 14 to open its injection port 1.
It is injected from 7.

In this headlamp cleaner, a water drain passage 5 is formed in the nozzle case 1, and the water drain passage 5 is located below the position of the injection port 17 of the nozzle body 14 in the nozzle body holding recess 4. Since it extends from the position and opens to the outside of the nozzle case 1 below the position, rainwater etc. are discharged to the outside of the nozzle case 1 through this drainage passage 5.

Therefore, rain and ice will not accumulate until the injection port of the nozzle body is buried in the holding recess, and the nozzle body will not protrude from the nozzle case even in part, and cleaning water will not be sprayed in cold regions. It is possible to eliminate the problem of being disabled.
