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, the cleaning device comprising:
at least one cleaning agent feed line;
at least two cleaning agent spraying elements;
at least two bores, wherein each one of the at least two cleaning agent spraying elements is arranged on one of the at least two bores; and
an annular channel connected to the cleaning agent feed line and on which the at least two bores are arranged connecting the annular channel to the cleaning agent spraying elements, the annular channel includes an annular channel lid on which the cleaning agent spraying elements are arranged and a lower half directly linked to the at least one cleaning agent feed line.

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. 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;
at least two cleaning agent spraying elements;
at least two bores, wherein each one of the at least two cleaning agent spraying element is arranged on one of the at least two bores; and
an annular channel connected to the cleaning agent feed line and on which the at least two bores are arranged connecting the annular channel to the cleaning agent spraying elements, the annular channel includes an annular channel lid on which the cleaning agent spraying elements are arranged and a lower half directly linked to the at least one cleaning agent feed line.

7. A cleaning device for cleaning a transparent cover of a camera, the 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;
the housing defining an opening extending from the receptacle and configured to receive the transparent cover of the camera;
the housing defining a second fluidic channel disposed around the opening and coupled to the first fluidic channel, the second fluidic channel includes a channel lid and a lower half directly linked to the feed line;
the housing further comprising a plurality of spraying elements wherein each spraying element defines a spray opening and wherein each spray opening is coupled to the second fluidic channel.

8. The cleaning device according to claim 7 , wherein the channel lid is removably coupled to the lower half and wherein the plurality of spraying elements are disposed on the channel lid.

9. The cleaning device according to claim 8 , wherein the lower half defines a portion of the second fluidic channel and the channel lid defines a portion of the second fluidic channel.
