Description
Technical field
The utility model relates to a kind of camera, is 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.
Utility model content
In view of this, the utility model provides a kind of camera with dust reduction capability, and described camera structure is simple, anti-dust performance good, can effectively prevent job site bisque to the pollution of camera.
The purpose of this utility model is realized by following technical scheme:
Have a camera for dust reduction capability, described camera comprises end cap and is sleeved on the annular dirt-proof boot outside camera body; Described camera body is fixed on end cap, and the length of described annular dirt-proof boot is greater than the length of camera body; And one end of described annular dirt-proof boot and end cap affixed, the other end is radially provided with the annular protrusion extended internally; Air chamber is formed between described annular dirt-proof boot and camera body; Described annular dirt-proof boot is provided with two or more air admission hole; Described air admission hole is communicated with air-source by sebific duct;
The circumferencial direction of described air admission hole annularly dirt-proof boot is uniformly distributed;
Described end cap and annular dirt-proof boot are integral type structure;
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;
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 described in the utility model 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 described in the utility model.
Wherein, 1-end cap, 2-annular dirt-proof boot, 3-camera body.
Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, the utility model is described in detail.
The utility model provides a kind of camera with dust reduction capability, the annular dirt-proof boot 2 that described camera comprises end cap 1 and is sleeved on outside camera body; Described camera body 3 is fixed on end cap, and the length of described annular dirt-proof boot 2 is greater than the length of camera body 3; And one end of described annular dirt-proof boot 2 and end cap 1 affixed, the other end is radially provided with the annular protrusion extended internally; Air chamber is formed between described annular dirt-proof boot 2 and camera body 3; Described annular dirt-proof boot 2 is provided with two or more air admission hole; Described air admission hole is communicated with air-source by sebific duct;
The circumferencial direction of described air admission hole annularly dirt-proof boot 2 is uniformly distributed;
Operation principle: air enters by being formed in air chamber between annular dirt-proof boot 2 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 utility model, be not intended to limit protection range of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
