Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning technique for an automobile navel cleaner that spouts washing water for washing the headlights of an automobile while the vehicle is running. It concerns an ultra-wide-angle nozzle.

[Conventional technology]

Conventionally, headlamp cleaners have been used to clean mud, insects, etc. that adhere to the front of a car's headlights while driving, and restore the headlamp's light emission performance by directing high-pressure washing water from a nozzle toward the headlamp surface. A type with a spouting structure is used.

[Problem that the invention seeks to solve]

However, 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. There are an increasing number of thin and wide headlamps.

For this reason, the cleaning water sprayed out from the headlamp cleaner does not reach the entire headlamp surface, leaving some residue behind. This has caused problems such as an increase in the amount of cleaning water used and a decrease in cleaning efficiency.

The present invention was devised in view of the above-mentioned problems, and controls the spray shape so that the sprayed cleaning water is spread over an ultra-wide angle in accordance with the surface shape of the headlamp, and also prevents the formation of unwashed water. It is an object of the present invention to provide an ultra-wide-angle nozzle for a headlamp cleaner that can effectively utilize the limited amount of cleaning water.

[Means for solving problems]

That is, in the ultra-wide-angle nozzle for a headlamp cleaner according to the present invention, the injection port opening at the end of the cylindrical portion is structured in a special shape, and the high-pressure cleaning water jetted from the injection port is controlled in a predetermined shape. In a headlamp cleaner that sprays high-pressure washing water onto automobile headlamps to restore the light emission efficiency, the cylindrical wall of the short cylindrical portion that communicates with the washing water supply section and the cylindrical wall of the short cylindrical portion are The end wall surface of the top wall formed at the end portion forms a vortex forming cavity, and at the front end of the top wall, a water cut edge whose front shape is curved upward is formed. A curved edge whose front shape is upwardly curved or straight is formed at the upper end of the front half of the cylindrical part, and a cleaning water injection port is provided in which the curved edge and the cut edge are connected at both ends by side edges of appropriate curvature. The gist is that it opens into the vortex forming cavity.

[Effect]

The ultra-wide-angle nozzle for headlamp cleaners supplies high-pressure cleaning water at an appropriate pressure to the vortex-forming cavity, and the cleaning water supplied to the vortex-forming cavity is applied to the water cutting edge by the water flow flowing out from the cleaning water jet port. A high-speed vortex is formed in the upper wash water separated by the wash water in the vicinity of the wash water injection port. Due to this vortex, when the cleaning water jetted from the cleaning water jetting port is rapidly depressurized, it becomes water droplets and is regulated by the arc-shaped water incisal edge, curved edge, and side edge. It ejects in the direction of the jet and hits the front of the headlamp at high speed.

The above-mentioned ultra-wide-angle nozzle for headlamp cleaner controls the cleaning water to be sprayed over the entire surface of the thin and wide ultra-wide-angle headlamp by the upwardly curved shape of the cutting edge and the curved edge that make up the cleaning water injection port. It does not leave any residue after washing.

〔Example〕

Embodiments of the ultra-wide-angle nozzle for headlamp cleaners according to the present invention will be described below with reference to the drawings.

It is a short cylindrical part,
The spherical base 2 is fitted into a spherical recess 52 formed at the end of the nozzle case 51 so that its fixed position can be adjusted, thereby forming a headlamp cleaner 50 for fixing the cleaning water injection nozzle to a bumper a of an automobile or the like. . The short cylindrical portion 1 has a cylindrical wall 3 bored from the end of the spherical base 2 to the axis O, and an end wall surface 5 of a beak-like top wall 4 formed at the end of the short cylindrical portion 1. A vortex forming cavity 7 is formed with a cleaning water injection port 6 opened at the end side. The front end 4a of the beak-shaped top wall 4 is set back slightly d from the inner diameter of the cylinder wall 3, and the side edges 4b, 4b extending at an angle α of approximately 90 degrees from the front end 4a are approximately 180 degrees apart from the inside diameter of the cylinder wall 3. The cutting edge 8 has a planar shape that intersects at the angle position, and the hanging width gradually decreases from the front end 4a of the beak-shaped top wall 4 along the side edge 4b, and the frontal shape is curved in one direction.
, and forms the upper edge of the cleaning water injection port 6. Further, reference numeral 9 denotes a curved edge formed at the front half-upper end of the short cylindrical portion 1 in correspondence with the water cut edge 8, and the front surface is curved upward, and the end surface 9a is slightly curved toward the cylindrical wall 3. (approximately 8 degrees), and the curved edge 9 and cut edge 8 are connected at both ends by side edges 10 of appropriate curvature, forming the front shape of the cleaning water injection port 6.

The ultra-wide-angle nozzle for a headlamp cleaner configured as described above supplies high-pressure cleaning water with an appropriate pressure to the vortex forming cavity 7 through the nozzle case 51, so that the cleaning water in the form of water droplets is released from the cleaning water injection port 6. Spout, left and right diffusion angle β is 140
degree, and the vertical diffusion angle T of 21 degrees can be achieved.

That is, the cleaning water supplied to the vortex forming cavity 7 flows through the water cut edge 8.
is located inside the cylindrical wall 3, the upper wash water separated by the water cut edge 8 due to the water flow flowing out from the wash water injection port 6 forms a high-speed vortex in the vicinity of the wash water injection port 8.

Due to this vortex, the cleaning water jetted from the cleaning water jetting port 6 becomes water droplets when it is discharged from the cleaning water jetting port 6 and is rapidly depressurized, and forms an arcuate water incisal edge 8, a curved edge 9, and a water droplet. The injection control section A ejects in the injection direction whose injection range is regulated by the A curve, B curve, and C curve formed in the side edge 10, and corresponds to each of the above curves as shown in FIG. ,B.

It forms a spray pattern having a curve C and hits the front of the headlamp at high speed.

The ultra-wide-angle nozzle for the headlamp cleaner prevents the cleaning water from being sprayed outside the lens due to the upwardly curved shape of the cutting edge 8 and the curved edge 9 that make up the cleaning water injection port 6. The cleaning water is controlled so as to be sprayed over the entire surface of the thin and wide ultra-wide-angle headlamp, so that no residue is left behind.
