  • a secondary tank 13 is provided upstream of the cleaning liquid passages 11 a and 11 b, and a certain amount of cleaning liquid is accumulated in the secondary tank 13. Accordingly, the compressed air and the cleaning liquid accumulated in the secondary tank 13 can be mixed and sprayed onto the lens surface 1a of the camera 1, and the lens surface 1a can be cleaned with a small amount of cleaning liquid.
  • the secondary tank 13 is set to a negative pressure, the cleaning liquid is sucked from the cleaning liquid passages 11a and 11b, and the cleaning liquid is supplied to the combined passages 16a and 16b. And the compressed air are mixed and ejected from the discharge ports 10a and 10b, so that the cleaning liquid can be made mist and the amount of the cleaning liquid required for cleaning can be further reduced.
  • the pipe 23 (see FIG. 6) for supplying the cleaning liquid to the secondary tank 13 is oriented in the vertical direction. That is, the connection part of the cleaning liquid pipe to the secondary tank 13 is provided in the vertical direction. Therefore, when the supply of the cleaning liquid from the cleaning liquid pump 3 (see FIG. 1) is stopped, it is possible to prevent the cleaning liquid accumulated in the pipeline from inadvertently flowing into the secondary tank 13. For this reason, for example, when jetting compressed air in the air blow mode, it is possible to prevent the cleaning liquid from being mixed.

Since it is arranged to be inclined downward toward 10b, the cleaning liquid accumulated in the secondary tank 13 and the cleaning liquid passages 11a, 11b is sent to the discharge ports 10a, 10b without remaining. Therefore, the remaining cleaning liquid can be prevented from being ejected irregularly.
  • the compressed air and the cleaning liquid are combined at the tip of the nozzle 7.
  • the present invention is not limited to this, and the air passage and the cleaning liquid passage are arranged close to each other.
  • the cleaning liquid supplied from the cleaning liquid passage may be jetted in a mist form using the negative pressure at this time.
  • the tip portions 14a and 15a and 14b and 15b shown in FIG. 4 (b) do not merge and are jetted in a state where they are close to each other.
  • the present invention can be used for effectively cleaning the lens surface of a camera mounted on a vehicle with a small amount of cleaning liquid.
  • the cleaning liquid necessary for cleaning is stored in the secondary tank in advance, so it is possible to hold an appropriate amount of cleaning liquid in advance, and it is effective with less cleaning liquid without discharging excess cleaning liquid.
  • the lens surface can be cleaned.

Abstract

Selon l'invention, un trajet d'air (12) et deux systèmes de trajets de liquide de nettoyage (11a, 11b) sont agencés à l'intérieur d'une buse (7), et le trajet d'air (12) est dévié en deux systèmes de parties extrémité avant (14a, 14b). Un réservoir secondaire (13) est agencé en amont des trajets de liquide de nettoyage. En outre, une partie extrémité avant du trajet de liquide de nettoyage (11a) et la partie extrémité avant (14a) du trajet d'air (12), se rejoignent, et une partie extrémité avant du trajet de liquide de nettoyage (11b) et la partie extrémité avant (14b) du trajet d'air (12). Par conséquent, lorsqu'un air comprimé alimente le trajet d'air (12), comme une pression négative se crée à l'intérieur du réservoir secondaire (13) par cet écoulement d'air, un liquide peut être aspiré sous forme de brume, et une face de lentille (1a) d'une caméra peut être nettoyée par mélange du liquide de nettoyage sous forme de brume et de l'air comprimé. Enfin, la quantité de liquide de nettoyage mis en œuvre, peut être réduite par transformation de ce dernier en brume.
