Description

[Detailed Description of the Invention] The present invention relates to a water droplet adhesion prevention device installed on the side mirror of an automobile.

This type of pest control device, as shown in the devices disclosed in, for example, Japanese Utility Model Application Publication No. 56-46450 and Japanese Utility Model Application Publication No. 56-70458, basically involves spraying fluid (e.g. This is done by scattering water droplets, but in the case of the previous example, the cost rose because the motor and fan were installed inside the mirror body, and in the case of the rear side, the compression was done by mechanical means such as a compressor. Since it adopts a configuration that generates air, it also has the drawbacks of increasing costs and complicating the mechanism itself, as in the previous example.

The present invention was made in view of the above circumstances, and we devised a jet flow forming tube with an air inlet at one end and a jet nozzle at the other end, and incorporated it into a side mirror or made it detachable. The above-mentioned drawbacks can be solved at a relatively low price simply by installing the device.

The present invention will be explained below based on the illustrated embodiments.

The water droplet adhesion prevention device for side mirrors according to the present invention is the first
4, a jet flow forming tube 1 is provided on a side mirror 2, and the tube 1 has an air introduction port 1a at one end and an air introduction port 1a at the other end. l or a plurality of jet nozzles 1b communicating with the mouth 1a
There is.

Further, the air inlet 1a of the tube body 1 is opened in the running direction of the car, and the tip of the jet nozzle 1b is designed to spray a jet stream of air onto the mirror surface 3 of the side mirror 2 when the car is running. The mirror surface 3 is provided at a facing position.

In the case of this example, the tube body 1 is assembled inside the side mirror 2, and the air inlet 1a is located in the notch 40 formed at the front of the side mirror 2.
A plurality of jet nozzles 1b are formed and arranged above the mirror surface 3.

Note that the speed of the jet flow in the jet nozzle 1b is proportional to the area of the air inlet 1a divided by the area of the jet nozzle 1b, so these areas are determined with this point in mind.

Regardless of its name, the ejection nozzle 1b may have any shape as long as it can eject air (jet stream) from the air inlet 1a, and may be arranged not only on the upper part of the mirror surface 3 but also on the side,
It may be provided at the diagonal upper part or any other location as appropriate.

Further, a dust-proofing net 5 is attached to a suitable position inside the air inlet 1a.

This is used to prevent dust clogging of the jet nozzle 1b, and also to avoid a situation where sand or the like flies out from the jet nozzle 1b and damages the mirror surface 3 even if dust clogging does not occur.

Reference numeral 6 denotes a plastic or rubber tube whose tip communicates with the tube body 1 and whose other end is inserted into a container (not shown).

This is done by filling a container with a liquid such as an anti-fog agent or an antifreeze agent, and sucking it into the pipe body 1 using the principle of spraying while driving or by driving a pump with a motor, and then sucking it into the pipe body 1 and applying it to the mirror surface 3.
It was designed to be sprayed on.

In the embodiment shown in FIG. 5, the nozzle 1b is configured to be removably screwed onto the tube body 1, and the jetting portion of the nozzle 1b is made of a flexible material, thereby ensuring that the jet stream is directed in the jetting direction. In addition to making it possible to change the nozzle, the nozzle can be replaced with another nozzle as necessary, or maintenance etc. can be facilitated.

In addition, in the embodiment shown in FIG. 6, in contrast to the case where the tube body 1 was assembled inside the side mirror 2 in the previous example, the tube body 1 of the present invention is attached to the side mirror 2 from the outside. The purpose is to prevent water droplets from adhering to the mirror surface 3.

The water droplet adhesion prevention device for side mirrors according to the present invention is configured by providing the jet stream forming tube described above on the side mirrors, so that the jet stream itself is supplied to the motor or other fluid generating source when the car is running. This method has the excellent effect of not only reducing manufacturing costs but also easily and reliably preventing water droplets by using a jet stream.
