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 length of the dust-proof sleeve is greater than the length of the camera main body; one end of the dust-proof sleeve is fixedly connected with the end cover, and the part, which extends out of the camera main body, of the other end of the dust-proof sleeve is of a conical structure which shrinks inwards; the diameter of a small end of the conical structure is not smaller than the diameter of a camera lens; a gas cavity is formed between the dust-proof sleeve and the camera main body; an annular surface, which corresponds to the gas cavity, of the end cover 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
The present invention relates to a kind of camera, be specifically related to a kind of camera with dust reduction capability.
Background technology
For monitoring the job site in building site, camera need be laid at the construction field (site), but due to job site dust more, the camera for monitoring is easy to by dust pollution and then affects monitoring image effect, in order to ensure the definition of monitoring image, need regularly manually to clean camera.
Summary of the invention
In view of this, the invention provides a kind of camera with dust reduction capability, described camera structure is simple, anti-dust performance good, can effectively prevent job site bisque to the pollution of camera.
Object of the present invention is realized by following technical scheme:
Have a camera for dust reduction capability, described camera comprises end cap and is sleeved on the dirt-proof boot outside camera body; Described camera body is fixed on end cap, and the length of described dirt-proof boot is greater than the length of camera body; One end and the end cap of described dirt-proof boot are affixed, and the part that the other end stretches out camera body is the pyramidal structure of inwardly shrinking, and the end diameter of this pyramidal structure is not less than the diameter of cam lens; Air chamber is formed between described dirt-proof boot and camera body; Ring surface corresponding with air chamber on described end cap is provided with two or more air admission hole, described air admission hole is communicated with air-source by sebific duct.
Described air admission hole is uniformly distributed along the circumferencial direction of end cap.
Described end cap and dirt-proof boot are integral type structure.
Described dirt-proof boot is provided with two or more air admission hole, described air admission hole is communicated with air-source by sebific duct.
Described air admission hole is uniformly distributed along the circumferencial direction of dirt-proof boot.
Operation principle: air is entered by air admission hole and formed in air chamber by between annular dirt-proof boot and camera body, the air-flow of flowing produces gas field in the front portion of camera lens, form dust-separation district, the dust in environment can be avoided to drop on camera lens, maintain the cleannes of camera lens, ensure that the normal clearly shooting picture of camera.
Beneficial effect:
Camera structure of the present invention is simple, anti-dust performance good, job site bisque effectively can be prevented the pollution of camera, can carry out continuous surveillance to job site.
Accompanying drawing explanation
Fig. 1 is a kind of cross-sectional view with the camera of dust reduction capability of the present invention.
Wherein, 1-dirt-proof boot, 2-end cap, 3-camera body
Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
The invention provides a kind of camera with dust reduction capability, the dirt-proof boot 1 that described camera comprises end cap 2 and is sleeved on outside camera body; Described camera body 3 is fixed on end cap, and the length of described dirt-proof boot 1 is greater than the length of camera body 3; One end and the end cap of described dirt-proof boot 1 are affixed, and the part that the other end stretches out camera body 3 is the pyramidal structure of inwardly shrinking, and the end diameter of this pyramidal structure is not less than the diameter of cam lens; Air chamber is formed between described dirt-proof boot 1 and camera body 3; Ring surface corresponding with air chamber on described end cap 2 is provided with two or more air admission hole, and described air admission hole is communicated with air-source by sebific duct.
Described air admission hole is uniformly distributed along the circumferencial direction of end cap 2.
Operation principle: air enters by being formed in air chamber between annular dirt-proof boot 1 and camera body 3 by air admission hole, the air-flow of flowing produces gas field in the front portion of camera lens, form dust-separation district, the dust in environment can be avoided to drop on camera lens, maintain the cleannes of camera lens, ensure that the normal clearly shooting picture of camera.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
