じるという問題を有していた。However, in recent years, headlamps have become a part of car design, and so-called proper headlamps have become mainstream, and thin and wide headlamps are generally preferred when considering car design and air resistance. The number is increasing. For this reason, the cleaning water that is diffused and jetted from the headlamp cleaner does not reach the entire headlamp surface, leaving some residue behind. However, if the jet shape is controlled so that the entire surface of the headlamp can be washed away, the headlamp can be sprayed with five points. There was a problem in that the pressure distribution of the cleaning water was uneven, resulting in a difference in cleaning between the center and the outer periphery.
本発明は、上記問題に鑑みて創案されたもので、洗浄水

とを要旨とするものである。The wide-angle nozzle for a headlamp cleaner according to the present invention is used in a headlamp cleaner that sprays high-pressure washing water onto the headlamp of an automobile to restore its light emission efficiency, and the cylindrical wall of a short cylindrical part that communicates with a washing water supply section. and a vortex forming cavity is formed at the top by the inner surface of the top wall formed at the end of the short cylindrical portion,
On one side of the vortex forming cavity, a water cut edge whose front shape is curved downward or straight at the upper end of the front half of the short cylinder part;
A cleaning water injection port is opened, which is connected at both ends to a spray direction regulating edge whose front edge projects in a beak shape corresponding to the water cutting edge, and a vortex forming cavity at the inner end on the water cutting edge side is formed in the washing water injection port. The main feature is that a bead protrusion for forming turbulent flow is provided protruding from the side.

御して均一洗浄ができる。The wide-angle headlamp cleaner nozzle forms a high-speed water stream in which the cleaning water supplied to the vortex forming cavity at an appropriate pressure flows out from the cleaning water jet port. However, since a bead protrusion is formed at the inner end of the cleaning water injection port, the upper cleaning water separated at the core portion forms a high-speed vortex in the vicinity of the cleaning water injection port. This vortex flow is a turbulent flow in which the center of the vortex constantly vibrates due to the water flow direction changing action of the bead protrusion, so that the cleaning water jetted from the cleaning water jetting port is rapidly depressurized. At the same time as becoming water droplets,
It ejects in a direction regulated by the fountain direction regulating edge and water cutting edge, and hits the front of the headlamp at high speed. At this time, the beak-shaped fountain direction regulating wall constituting the cleaning water jetting port extends in the cleaning water jetting direction and has a predetermined opening angle with the water cut edge, so that the cleaning water spouted in an upward diagonal direction is The jet of water is controlled to the surface shape of the thin and wide ultra-wide-angle headlamp facing the cleaning water jet port, and at the same time, the jet density of droplets is controlled to achieve uniform cleaning.

これを吹き飛ばして除去する優れた作用を発揮する。That is, when cleaning water is supplied to the swirl forming cavity 8, since the swirl forming cavity 8 is configured with the bead protrusion 11, the cleaning water is jetted out at the inner edge of the water fountain direction regulating edge 9 by the water flow flowing out from the cleaning water injection lower. The upper washing water separated from the water forms a high-speed vortex near the washing water injection lower part, and collides with the inner wall surface 6 to forcibly change direction, causing the center of the vortex to constantly vibrate. The flow becomes turbulent. Due to the turbulent flow, the water pressure near the cleaning water injection lower becomes pulsating.
The cleaning water spouted from the cleaning water injection lower is discharged from the cleaning water injection lower and is rapidly depressurized and becomes water droplets.
The water is ejected in a direction regulated by the water fountain direction regulating edge 9 and the water cutting edge 10, and hits the front surface of the headlamp at high speed. When this droplet-shaped cleaning water is sprayed onto the headlamp surface, it exhibits an excellent effect of forcibly peeling off dirt adhering to the surface to be cleaned and at the same time blowing it away.
