Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a self-cleaning mechanism for a security camera. Background Art

[0002] Security cameras are cameras used for security monitoring. For security cameras installed outdoors, dust is likely to adhere to the lenses of security cameras. After the dust accumulates for a period of time, the lens will become blurred, affecting the shooting effect of the security camera. The existing air-blowing self-cleaning mechanism for cameras has the following problems: 1. After air blowing, the dust will spread in the surrounding air. When the air blowing stops, the dust in the surrounding air is likely to adhere to the lens again; 2. The angle of the air blown out cannot be adjusted, so that the position where the air blows onto the lens cannot be adjusted on site. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above problems existing in the prior art, and provide a self-cleaning mechanism for a security camera.

[0004] To achieve the above technical purpose and reach the above technical effect, the utility model is realized through the following technical solutions:
