Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a headlamp cleaner for an automobile that spouts cleaning water for cleaning the headlamp of an automobile while the vehicle is running, and in particular, the invention relates to a headlamp cleaner for an automobile that spouts cleaning water for cleaning the headlamp of an automobile while the vehicle is running. The present invention relates to an automotive head lamp cleaner that can be designed to provide a clear design and that does not leave water pools between parts after spraying cleaning water.

[Conventional technology]

Conventionally, a nozzle with a cleaning water spray nozzle on the top of a nozzle case fixed to the bumper has been used as a device to clean mud, insects, etc. that adhere to automobile headlamps while driving and restore light emission performance. A headlamp cleaner with an integrated holder fitting structure is used.

[Problem to be solved by the invention]

However, in the structure of this type of headlamp cleaner, the fitting portion in the press-fitting structure that integrates the nozzle holder with the nozzle case requires highly accurate design and manufacturing, resulting in a problem of rising manufacturing costs. On the other hand, if the pressure-mixed portion is loose, there is also the problem that when water is supplied to the washing water injection nozzle at high water pressure, the washing water injection nozzle comes off.

In addition, since both members of the press-fit structure are in close contact with each other, after the cleaning water is sprayed, the cleaning water collects in the recess of the nozzle case, and if this freezes, the next problem is that the cleaning water cannot be sprayed. It also had

The present invention was devised in view of the above problems, and in an automobile headlamp cleaner in which a nozzle case and a nozzle holder are separated, it is possible to roughly design the structure of the fitting part of the two, and it is easy to clean. The purpose of the present invention is to prevent a water injection nozzle from accidentally coming off due to water pressure, and to eliminate water accumulation after injection of cleaning water.

[Means for Solving the Problems] In order to achieve the above object, the headlamp cleaner for an automobile according to the present invention is made of a suitable material such as synthetic resin or rubber, which is fixed to the automobile body through a suitable mounting means. A transparent window is provided at the upper end of the nozzle case, and a cylindrical fitting part is formed facing inward continuously from the transparent window, and the spherical base of the cleaning water injection nozzle is connected to the cylindrical fitting part. A nozzle holder comprising a fitting cylinder shaft portion forming a fitting recess formed in a dynamically adjustable and airtight fitting manner is installed inside the nozzle holder;
A flange formed at the lower part of the fitting cylindrical shaft part of the nozzle holder is screwed and fastened to a screw port formed on the inner surface of the nozzle case, and a vertical recess is formed on the inner peripheral surface of the cylindrical fitting part of the nozzle case. The gist is that a groove is formed and a notch communicating in the outer radial direction is formed at the lower end of the groove.

[Effect]

According to the above configuration, the cylindrical fitting part of the nozzle case and the fitting cylindrical shaft part of the nozzle holder are fitted with mutual play, and the structure of the fitting part of both is designed and manufactured with high precision. There is no need to do this.
In addition, the cleaning water injection nozzle is firmly fixed to the nozzle case by screwing into the nozzle holder, and the spherical base of the cleaning water injection nozzle can be rotated and adjusted in the fitting cylinder shaft of the nozzle holder, and is airtightly fitted into the nozzle holder. Because of this, the high water pressure will never escape from the nozzle holder during cleaning.

In addition, after spraying the cleaning water, the cleaning water comes to escape through the vertically penetrating gap between the nozzle case and the nozzle holder, so the standing water freezes.
This eliminates problems such as the inability to spray cleaning water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the automotive headlamp cleaner according to the present invention will be described below with reference to the drawings.

1 and 2 show a first embodiment of the present invention.

In the drawings, reference numeral 1 denotes a nozzle case made of a suitable material such as synthetic resin or rubber. A transparent window 2 opened at the upper end of the nozzle case 1 is continuously formed with a cylindrical fitting part 3 (inner diameter D1) facing inward, and the transparent window 2 is formed on the side wall of the cylindrical fitting part 3. A groove 4 is formed on the inner peripheral surface of the cylindrical fitting part 3 over the entire length, and a notch 5 is formed at the lower end of the groove 4 to communicate in the outer radial direction. It consists of

Reference numeral 6 designates a nozzle holder made of a suitable synthetic resin material, and has a fitting recess 9 formed at the upper end in which the spherical base 8 of the cleaning water injection nozzle 7 is fitted airtightly and whose rotational displacement is adjustable. It constitutes a mating cylinder shaft part 10 and has a connecting pipe 11 protruding from the fitting cylinder shaft part 10 that communicates with the fitting recess 9.
The connecting pipe 11 is bent at an angle at an intermediate position as necessary. Here, the outer diameter D2 of the fitting cylinder shaft portion 10 is
is configured to have a smaller diameter than the inner diameter D1 of the cylindrical fitting part 3 of the nozzle case 1, and the two form a considerably loose fitting structure G. Tapping screws 1 are inserted into the small holes 13, 13 made in the flange 12 formed in the
4 is inserted into the nozzle case 1, and the screw ports 15, 15 formed on the inner surface of the nozzle case 1 are screwed together and fixedly integrated. Forms a communication path.

Further, the cleaning water injection nozzle 7 has a water sprinkling protrusion 17 projecting from the mouth end of a water passage hole 16 formed through the axial center of the spherical base 8, and a water sprinkling protrusion 17 which is partially covered at the mouth end of the water passage hole 16 formed through the spherical base 8 at the axial center position. A nozzle collar 18 that opens toward the water sprinkling projection 17 is fitted, and when the cleaning water jet nozzle 7 is fitted into the nozzle holder 6, the water sprinkling projection 17 is connected to the transparent window 2 of the nozzle case 1.
It is made to be carried so that it emerges from the body.

Reference numeral 19 denotes a clamp holding projection protruding from a position below the flange 12 of the nozzle holder 6, and when the lower end of the nozzle case 1 is installed on the upper surface of the automobile bumper a, the lower surface of the core bumper a and the clamp holding projection 19 A mounting means for press-fitting and fixing the plate-like clamp member b is formed between them.

Next, FIG. 3 shows another embodiment of the present invention in which the mounting means are different, and only the configuration different from the above embodiment will be described.

Reference numeral 20 denotes a stud bolt in which an upper bolt portion 21 is screwed into and protrudes from a screw port 15, and at the same time as the stud bolt 20 is fastened, a fastening plate 23 protruding from the nozzle holder 6 is fixedly integrated. Therefore, the headlamp cleaner can be fixedly installed on the bumper a by using the lower bolt portion 22 extending to the other end of the stud bolt 20, which is previously drilled to correspond to the position of the stud bolt 20. Insert the lower bolt part 22 into the bumper a side mounting hole,
