Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0016] A schematic diagram of the cross-sectional structure of a camera with dustproof function is shown in figure 1 As shown, the camera includes an end cap 2 and a dust-proof cover 1 set outside the camera body; The length of; the large end of the dust-proof cover 1 is affixed to the end cap, and the diameter of the small end is not less than the diameter of the camera lens; a gas cavity is formed between the dust-proof cover 1 and the camera main body 3; the dust-proof cover 1 There are more than two air intake holes; the air intake holes communicate with the air source through rubber hoses.

[0017] The air inlet holes are evenly distributed along the circumferential direction of the dustproof cover 1 .

[0018] Working principle: Air enters the gas cavity formed between the annular dustproof cover 1 and the camera body 3 through the air intake hole,...

Abstract

The invention discloses a camera with a dust-proof function. The camera comprises an end cover and a dust-proof sleeve which sleeves the outer side of a camera main body, wherein the camera main body is fixedly arranged on the end cover; the dust-proof sleeve is a conical cylinder, and the length of the dust-proof sleeve is greater than the length of the camera main body; a big end of the dust-proof sleeve is fixedly connected with the end cover; the diameter of a small end of the dust-proof sleeve is not smaller than the diameter of the camera lens; a gas cavity is formed between the dust-proof sleeve and the camera main body; the dust-proof sleeve is provided with more than two air inlet holes; the air inlet holes are communicated with an air source through a rubber tube. Air enters the gas cavity formed between the annular dust-proof sleeve and the camera main body from the air inlet holes, and the flowing air flow produces an air field on the front part of the lens to form a dust isolation region, so dust in an environment can be prevented from falling on the lens, the cleanness of the lens is kept, and normal clear picture photographing of the camera is guaranteed.

Description

technical field [0001] The invention relates to a camera, in particular to a camera with a dustproof function. Background technique [0002] In order to monitor the construction site of the construction site, it is necessary to deploy cameras on the construction site. However, due to the large amount of dust in the construction site, the cameras used for monitoring are easily polluted by dust and affect the effect of monitoring images. In order to ensure the clarity of monitoring images, it is necessary to regularly Manually clean the camera. Contents of the invention [0003] In view of this, the present invention provides a camera with a dust-proof function. The camera has a simple structure and good dust-proof performance, and can effectively prevent the camera from being polluted by the powder layer on the construction site. [0004] The purpose of the present invention is achieved by the following technical solutions: [0005] A camera with a dustproof function, the...
