になった。BACKGROUND ART Conventional jet headlamp cleaning devices have used a jetting pattern of a cleaning liquid in the form of a full cone. In this method, the cleaning liquid sprayed onto the headlamp lens is dispersed before colliding with the lens, and the cleaning liquid particles are further miniaturized by air resistance, which significantly reduces the energy of the cleaning liquid colliding with the lens surface. For this reason, cleaning performance is extremely low, especially when it comes to dirt that is stuck to the lens surface of the headlamp, such as mud that has dried. , Yoshi mud,
This has the drawback of creating a state in which dust is likely to adhere. Furthermore, in recent years, many automobile headlamps have been adopted with rectangular or unusually shaped lens surfaces that are oblong rather than circular.

中心線上にＶ字型切込み形成して成る洗浄装置がある。For this purpose, as shown in FIGS. 1 and 2, a front view of a nozzle having a flat (fan-shaped) spray pattern in which the spray pattern 2 of the cleaning liquid from the nozzle 3a to the lens 1 of the headlamp is narrowed in the vertical direction and is sprayed in a concentrated manner. 3 is shown in FIG. 3, and the AA cross section is shown in FIG. 4. There is a cleaning device in which the discharge portion 5a of the nozzle is formed with a V-shaped cut on the center line of the internal hemispherical hole.
しかしこの噴射パターンの洗浄装置ではヘッドランプの
レンズ１の隅に付着した汚泥を洗浄することが困難であ

本発明の目的は上記欠点を解消した。洗浄液を集中噴射
し、且つ洗浄液のレンズ面への衝突面積を広くすること
によりヘッドランプの洗浄性を向上した噴射式ヘッドラ
ンプの洗浄装置を提供することにある。The object of the invention is to overcome the above drawbacks. An object of the present invention is to provide an injection type headlamp cleaning device that improves headlamp cleaning performance by spraying a cleaning liquid in a concentrated manner and widening the collision area of the cleaning liquid against a lens surface.

である。It is known that the ability to remove mud adhering to a headlamp using a spray cleaning method is proportional to the impact energy of the headlamp unit area 11) of cleaning particles colliding with the lens surface. Therefore, the present invention has developed a headlamp cleaning method with high cleaning performance, which makes the spray pattern of the cleaning liquid flat so that it can be sprayed in a concentrated manner, and by providing the spray pattern in an arcuate shape, it is possible to clean the entire P lens surface. It is a device.
以下本発明の実施例を図によシ説明する。 Embodiments of the present invention will be described below with reference to the drawings.

洗浄することが出来る。3C is provided. Cleaning liquid is sprayed onto the lens surface 1 from the spray nozzles 3b and 3c in a flat, horizontally wide and vertically narrow spray pattern. According to this spray pattern, the lens surface can be effectively cleaned over a wide range without making the cleaning liquid particles finer.

能でおる。The shape of the injection nozzle 3b that obtains the above injection pattern is shown below. Figures 7 and 8 are examples of the nozzle body 3.
A V-shaped notch 5b is provided offset from the center of the internal hole so as to communicate with the hemispherical internal hole 4 provided in b. Figures 1-1 and 12 show other examples in which a V-shaped notch 5C is provided in which the notch communicating with the hemispherical internal hole 4 is formed to form an arcuate and flat jet of the cleaning liquid. A pattern is obtained. Furthermore, when the cleaning device according to the present invention is installed on a vehicle, even if the position of the injection nozzle with respect to the five-head lamp is restricted, or depending on the shape of the lens surface of the headlamp, the injection nozzle is connected to the internal hemispherical hole. By appropriately determining parameters such as the direction of the V-shaped cut, the depth of the cut, and the angle of the cut, the entire lens surface of the headlamp can be cleaned, and higher cleaning performance can be obtained.

浄性を著しく向上するという効果がある。As described above, according to the present invention, an arcuate flat spray pattern is used to intensively spray the cleaning liquid from the spray nozzle, and in order to cause the cleaning liquid to collide with the lens surface of the headlamp, the sludge firmly attached to the lens surface is spread over both lenses. It has the effect of being washable and significantly improving the washability.
