Abstract

Cleaning device for cleaning a transparent cover of a camera, in particular a lens of the camera, comprising at least one cleaning agent feed line and at least two cleaning agent spraying elements.

First claim

What is claimed is:

1 . A cleaning device for cleaning a transparent cover of a camera, comprising:
at least one cleaning agent feed line; and at least two cleaning agent spraying elements; and at least one annular channel connected to the cleaning agent feed line and on which the cleaning agent spraying elements are arranged.

2 . The cleaning device according to claim 1 , wherein the cleaning agent spraying elements are configured above the annular channel.

3 . The cleaning device according to claim 2 , wherein the cleaning agent spraying elements are deflectors which are arranged on bores in the annular channel.

4 . The cleaning device according to claim 1 , wherein the cleaning agent spraying elements are configured inside the annular channel.

5 . The cleaning device according to claim 4 , wherein the cleaning agent spraying elements are spray nozzles which are configured or arranged inside the annular channel.

6 . The cleaning device according to claim 1 , wherein the annular channel is configured in two parts, having an annular channel lid on which the cleaning spraying elements are arranged or respectively configured.

7 . An optical detection device for arrangement in a vehicle, comprising:
a camera which is configured with a cleaning device having at least one cleaning agent feed line; and at least two cleaning agent spraying elements; and at least one annular channel connected to the cleaning agent feed line and on which the cleaning agent spraying elements are arranged.

8 . A cleaning device for cleaning a transparent cover of a camera, said cleaning device comprising:
a feed line defining a first fluidic channel; and a housing defining a receptacle configured to accommodate at least a portion of the camera; said housing defining an opening extending from said receptacle and configured to receive the transparent cover of the camera; said housing defining a second fluidic channel disposed around said opening and coupled to said first fluidic channel; said housing further comprising a plurality of spraying elements wherein each spraying element defines a spray opening and wherein each spray opening is coupled to said second fluidic channel.

9 . The cleaning device according to claim 8 , wherein the housing includes a main portion and a lid portion removably coupled to said main portion and wherein said plurality of spraying elements are disposed on said lid portion.

10 . The cleaning device according to claim 9 , wherein said main portion defines a portion of said second fluidic channel and said lid portion defines a portion of said second fluidic channel.
