Abstract

The utility model relates to a dust separator for digital single Iens reflex sensor (CCD), which belongs to a dust-removal device for digital camera image sensor and is particularly applicable to remove fine dusts on image sensors such as CCD or CMOS of the digital single lens reflex. The utility model is aimed to make the dust of CCD be easily removed without damage on components and electronic components, and simultaneously reduce cleaning expense and raise efficiency. The utility model comprises a wiping head and a gas pump. The utility model is characterized in that: the dust separator comprises a electric gas pump (1), a gas pipe (3) and a wiping head (6); wherein, the gas pie is a hollow pipe composed of two parts, one part being a round pipe (4) connected with the electric gas pump, the other part being a triangle tabular empty pipe (5) connected with the wiping head. The utility model has the advantages that the structure is simple, the cost is low, and all the dusts on CCD are removed completely through repeated suck and blow o the electric gas pump.

Description

The deduster of a kind of digital slr camera image sensor (CCD)

Technical field:

The deduster of a kind of digital slr camera inductor (CCD) belongs to the cleaner of digital machine image sensor, the micronic dust on the image sensors such as the CCD of the digital slr camera of outstanding suitable removal or CMOS.

Background technology:

We know that traditional camera chain is by shooting, and flushing put for three most compositions with seal, and the logarithmic code camera then by input, is handled and output three big portions.The optical imaging system of digital camera is as traditional camera, but its record image is not with traditional film, the input of digital camera is to accept imaging signal with image sensor, as CCD or CMOS etc., the numberization of image input is the characteristics of digital photography system, and these electronic signals of image are directly changed into digital signal are housed on the disk, this disk that digital image arranged can directly be handled by computer and be printed as image.

CCD is by hundreds thousand of extremely millions of solid-state electronic elements that the micro photo electric diode constitutes, and is used to accept to enter the imaging light of camera lens.Digital slr camera all may be brought dust into fuselage interior when using or change camera lens, and be attached on the image sensors such as CCD, dust can cause the fleck of imaging, if spot drops on the significant points of personage's hair or photo, is very nerve-wracking thing.And remove also not a duck soup, and just because of this, also just produced dedusting technology, the CCD dedusting technology call difference of each producer, but principle is roughly the same, the way of all adopt wiping, blowing.

Method commonly used;

1, the wiping head made with absorbent cotton or lens paper of conventional method is stained with a little solvent wiping CCD, pinches balloon with hand at last and dries up.

2, using camel's hair wiping head to add hand pinches balloon and dries up.

3, compressed air blows by force.

Above-mentioned dust collection method even quite carefulness is done, also differs and thoroughly remove the dirt of CCD surely, and powerful compressed air causes indirect damage to part and circuit.Afterwards, produced some special uses again and smeared tool and cleaning agent, as: smear the wiping head that excellent end is surrounded by absorbent cotton, drip one to two cleaning agent thereon, laterally smear the CCD face, hand is pinched balloon and is dried up CCD then.Because image sensor is very proud tender, said method is easy damaged CCD chip very.The special-purpose excellent tool of the mutually confidential selection different size of different model, the disposable use of excellent tool, normal condition will smear twice in average every month, each cleaning expense height, hand is pinched balloon and is used inconvenience, and effect is undesirable.

Summary of the invention:

The utility model proposes the deduster of a kind of digital slr camera image sensor (CCD), its objective is the dirt that makes image sensor to remove easily and do not damage the part and the electronic component of CCD image sensor and camera, reduce cleaning cost simultaneously and raise the efficiency.

The technical solution adopted in the utility model is: adopt the deduster that electronic air pump is arranged, with thorough removing CCD dust.

The deduster of a kind of digital slr camera image sensor (CCD) comprises wiping head, air pump, it is characterized in that deduster has electric air pump, tracheae and wiping head; Tracheae is a bipartite hollow tube: a part is the round tube that is connected with electric air pump, and another part is the triangle flat blank pipe that is connected with the wiping head.

The deduster of above-mentioned (CCD) is characterized in that described electric air pump is electronic asepwirator pump or electronic blower pump.

The deduster of above-mentioned a kind of digital slr camera image sensor (CCD) is characterized in that described wiping head is long stapled ventilative cotton, and it is enclosed within on the triangle flat blank pipe, and is fixed on tracheae with wiping the elastic ring that unloads.

The deduster of above-mentioned a kind of digital slr camera image sensor (CCD) is characterized in that the end and the planar delta of the triangle flat blank pipe of described tracheae has an angle.

The use of this cleaner, if use electronic asepwirator pump, the dust on the CCD is sucked away by triangle flat blank pipe.If use electronic blower pump, air blows on the CCD by the filtration of pipeline and wiping head, and the dirt on the CCD is blown away.Through the pressure-vaccum repeatedly of electric air pump, the dirt on the full scale clearance CCD.Because need not be to CCD surface wiping, so CCD can not damage.

Fig. 1 is the assembling schematic diagram of a kind of digital slr camera (CCD) deduster.

Fig. 2 is the electric air pump schematic diagram.

Fig. 3 is the tracheae schematic diagram.

Fig. 4 is that ventilative cotton-padded covering is at triangle flat blank pipe schematic diagram.

Among the figure:

Electric air pump 1, elastic seal ring 2, tracheae 3, round tube 4, triangle flat blank pipe 5, ventilative cotton 6, battery case 7, elastic ring 8.

Specific embodiment:

Now with specific embodiment explanation this programme.

Fig. 1 has shown the structure and the correlation of digital slr camera image sensor (CCD) deduster.Fig. 2-4 has expressed each design of part schematic diagram.(CCD) deduster is made up of electric air pump 1, tracheae 3, ventilative cotton 6.This example adopts the plunger type air pump, tracheae 3 is plastic hollow pipes, link by round tube 4 and triangle flat blank pipe 5, round tube is connected with electric air pump 1 usefulness elastic seal ring 2, triangle flat blank pipe end is wrapped up by ventilative cotton 6, the ventilative cotton terminal pipe part that is fixed on tracheae with elastic caoutchouc circle 8.

During use, the adept shank type battery case 7 of hand is operated, and tracheae 3 connects electronic plunger air pump 1, and the dust on the CCD is sucked away by triangle flat blank pipe 5.If use electronic blower pump, air blows on the CCD by pipeline and ventilative cotton 6 filtration, and the dirt on the CCD is blown away.Through the pressure-vaccum repeatedly of electric air pump, the dirt on the full scale clearance CCD.Because need not be to CCD surface wiping, so CCD can not damage.

Example of the present utility model simple in structure, dedusting is done quiet, and expense is low.
