Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a spray nozzle for cleaning liquid in automobiles.

[Background of the idea]

As a conventional cleaning liquid injection nozzle, there is one shown in FIG. 4, for example. This is a front air box 2 for ventilation formed between the windshield 1 and the bonnet, and a nozzle 3 is housed in the front air box 2 with the injection port facing the windshield 1. It is fixed to the vehicle body 6 with screws 5 via a fixing plate 4 fixed to the body.

However, in such conventional cleaning liquid injection nozzles, the nozzle 3 is fixed to the vehicle body 6 via the fixing plate 4, and the cleaning liquid is sprayed toward the windshield 1 at a fixed angle. Therefore, for example, if the spray angle of the nozzle 3 is adjusted by changing the mounting position of the fixing plate 4 etc. so that the cleaning liquid hits the appropriate position on the windshield 1 when the car is running at low speed, the spray will not be sprayed when the car is running at high speed. There was a problem in that the cleaning liquid was blown upward by the wind pressure and the position of the cleaning liquid was shifted, making it impossible to perform effective cleaning.

[Purpose of invention]

The present invention was developed by focusing on these conventional problems, and by making the injection angle of the nozzle variable according to the vehicle speed, the cleaning liquid can be sprayed onto the windshield at all speeds from low to high speeds. It is an object of the present invention to provide a cleaning liquid injection nozzle that can spray a cleaning liquid at an appropriate position.

[Example of idea]

The present invention will be explained in detail below based on the embodiments shown in FIGS. 1 to 3.

Reference numeral 10 denotes an injection nozzle bent into a letter shape in cross section, and a bracket 12 having a support shaft 11 is attached to the bent part.
is fixed, and a wing 13 whose front portion is curved upward is attached to the upper edge in front of the bent portion. The nozzle 10 is rotatably supported by a support shaft 11 on a vehicle body (not shown), so that it can swing vertically. Reference numeral 14 denotes a coil spring whose one end is connected to the rear of the bent portion of the nozzle 10 and whose other end is connected to the vehicle body (not shown) on the side of the windshield 1 with respect to the support shaft 11. The nozzle portion is urged toward the windshield 1 side. That is, the tip side of the nozzle 10 is always urged upward by the coil spring 14. Numeral 15 is an upper limit stopper for regulating the upper limit rotational position of the tip of the nozzle 10, and 16 is a lower limit stopper for regulating the lower limit rotational position.The tip of the nozzle 10 is always stopped against the upper limit stopper 15. Reference numeral 17 denotes a PVC tube whose one end is connected to the rear end of the nozzle 10 and the other end is connected to a pump of a cleaning liquid tank (not shown). When this pump is activated, the cleaning liquid is sprayed from the injection port of the nozzle 10 onto the windshield 1. It is sprayed towards.

The structure of this embodiment has been described above, and its operation will be explained next.

The blades 13 attached to the nozzle 10 are curved upward at the portion on the windshield 1 side, so when wind pressure is applied from the front of the windshield 1, the blades 13 are attached to the support shaft 11 of the nozzle 10. Since a counterclockwise rotating force acts on the center, the nozzle 10 is pushed downward against the spring force of the coil spring 14. In other words, when the car is running at low speed, the wind pressure is weak, so the wing 1
3 is weaker than the spring force of the coil spring 14, so the nozzle 10 is held in contact with the upper limit stopper 15, as shown in FIG. Cleaning liquid can be sprayed. Further, when the car is running at high speed, the wind pressure is strong, so the rotational force acting on the blade 13 becomes stronger than the spring force of the coil spring 14, and the nozzle 10 reaches the lower limit stopper 15 as shown in FIG. It is rotated and held in the hit state. Therefore, the cleaning liquid is injected low from the nozzle 10 and moves upward along the front surface of the windshield 1 on the wind that blows upward, so the injection position on the windshield 1 is the same as the injection position at low speed. The windshield 1 can be cleaned well in the same manner as at low speeds.

[Effects of embodiments of the invention]

As described above, according to this embodiment, the nozzle 10 is provided in front of the windshield 1 so as to be able to swing between the upper limit stopper 15 and the lower limit stopper 16, and the nozzle 10 is further provided with wings 13. Since the nozzle 10 is always held against the upper limit stopper 15 by the coil spring 14, the injection angle of the nozzle 10 can be varied depending on the wind pressure applied to the blades 13, so that the vehicle can run at low speed or high speed. However, the cleaning liquid from the nozzle 10 can be sprayed to a suitable position on the windshield 1, and the windshield 1 can be
This provides the effect of easily wiping off dirt such as oil film adhering to the surface.

[Summary of the idea]

As explained above, the present invention supports the injection nozzle 10 for vehicle cleaning liquid on the shaft 11 so as to be rotatable in the vertical direction, and is provided with the spring 14 that constantly urges the tip of the injection nozzle 10 upward. This spray nozzle for cleaning liquid is characterized in that the spray nozzle 10 is provided with wings 13 that push down the tip of the nozzle 10 by wind pressure against the force of the spring 14.

[Effect of idea]

Therefore, in the cleaning liquid injection nozzle according to the present invention, the injection nozzle 1 is heated by the wind pressure acting on the blade 13.
Since the injection angle of injection nozzle 1 can be changed, even if the car is running at high or low speed, the injection nozzle 1
Since the cleaning liquid injected from 0 is injected at a suitable position on the windshield 1, it is possible to easily wipe off dirt such as an oil film adhering to the windshield 1 by operating the wiper.
