Description

Digital camera image sensor dust catcher

Technical field

The utility model relates to the Clean-instrument of a kind of digital camera, specifically, relates to a kind of dust catcher that is specifically designed to cleaning digital camera image sensor.

Background technology

The single-lens reflex digital camera in use needs to change continually camera lens, this just can make magazine image sensor (CCD or CMOS) often be exposed in the air, and CCD itself often has a large amount of static, so just adsorb some fiber fines and dust in its surface inevitably.These fiber fines and dust can be along with the prolongations of camera service time and are constantly added up and cover on the surface of image sensor, if do not clean, the image sensor surface just can present mist, thereby make the picture of breaking forth the image or the dull burnt hair of picture color of booty occur, influence photographic quality.

The utility model content

The purpose of this utility model is to provide a kind of dust catcher that is used to clean the digital camera image sensor, and this dust catcher is directly removed the dust on image sensor surface, with the reduction photographic quality by the suction brush function of its suction nozzle.

For achieving the above object, the utility model has adopted following technical scheme:

A kind of digital camera image sensor dust catcher, it comprises housing and is installed in the suction pipe of housing one end, be provided with control circuit in the housing, this circuit is made of power supply, switch, motor series connection, motor output shaft is provided with impeller, and this impeller places the junction of housing and suction pipe, is provided with filter dirt box at impeller corresponding shell position, it is characterized in that: described dust catcher also comprises the suction nozzle that is plugged on suction pipe one end, and this suction nozzle is made by flexible material.

Described suction nozzle can be three types structure:

The suction inlet of described suction nozzle is a narrow long type.

Be provided with a wedge shape scraping blade in the suction inlet of described suction nozzle, the thin end of this wedge shape scraping blade convexedly stretches in the suction inlet outside and exposes.

The suction inlet place of described suction nozzle is enclosed with soft gas permeable material.

During use, the battery case of earlier two pieces of No. 5 AA batteries or rechargeable battery being packed into is opened the power supply of digital camera then, and screening-mode is made as M, and the focusing mode is made as MF.Then, unload camera lens, camera shutter speed is made as the B shelves, and press shutter.At this moment just can open the power supply of the utility model deduster, allow the suction nozzle of deduster vertically be close to the surface of image sensor CCD or CMOS, about back and forth gently wipe away the surface 1 to 3 time, the dust on image sensor surface just is eliminated.After cleaning was finished, the cameraman just can load onto camera lens, and with the alignment lens blank sheet of paper, the full width of cloth is taken a photo, to check the cleaning situation.

The utility model dust catcher aims at the dust of removing the image sensor surface and designs.This dust catcher can be finished the dedusting cleaning in 1-2 minute, its flexible suction nozzle can not scratch the image sensor surface.The utility model adopts No. 5 AA batteries or rechargeable battery powered, and volume is small and exquisite, and is economical and practical, carries use when being particularly suitable for location shooting and tourism photography.

The specific embodiment

As depicted in figs. 1 and 2, the utility model comprises housing 1 and is installed in the suction pipe 2 of housing 1 one ends, be provided with control circuit in the housing 1, this control circuit is made of power supply 31,

switch

32,33 series connection of 6V direct current generator, the output shaft of motor 33 is provided with an impeller 34, this impeller 34 places the junction of housing 1 and suction pipe 2, is provided with a filter dirt box 11 at impeller 34 corresponding shell positions, and this filter dirt box 11 is provided with exhaust outlet 111.End at suction pipe 2 is plugged with a suction nozzle 4, and this suction nozzle 4 is made by the flexible material such as rubber.

The utility model is furnished with three kinds of dissimilar suction nozzles.Fig. 3 a～3c is depicted as long narrow shape of the mouth as one speaks suction nozzle, and the suction inlet 41 of this suction nozzle 4 is a narrow long type.Fig. 4 a～4c is depicted as scraping blade type suction nozzle, is provided with a wedge shape scraping blade 42 in the suction inlet 41 of this suction nozzle 4, the thin end of this wedge shape scraping blade 42 as thin as a wafer, this thin end convexedly stretches in the outside of suction inlet 41 and exposes.Fig. 5 a～5c is depicted as the coated suction nozzle, and suction inlet 41 places of this suction nozzle 4 are enclosed with soft gas permeable material 43.Because the utility model suction nozzle is made by flexible material, so except the fiber fines and dust that can effectively suck the image sensor surface, the more important thing is, it can alleviate wearing and tearing and scuffing to the image sensor surface to greatest extent.

Operation principle of the present utility model is as follows:

Press switch 32, power supply 31 is connected, motor 33 (micromachine) impeller 34 rotation at a high speed, and the impeller 34 of rotation at a high speed produces suction, thereby makes the air on image sensor surface form eddy current by suction pipe 2 and suction nozzle 4.Under the acting in conjunction of suction and ambient air pressure, the image sensor surface produces Negative Pressure Difference, thereby the dust on surface is sucked in the suction pipe 2 with air at high speed along with gently wiping away of suction nozzle 4, and under the turning effort of impeller 34, air and dust enter in the filter dirt box 11, dust adhesion is on the filter disc of filter dirt box 11, and the air that is filtered is discharged at a high speed from the exhaust outlet 111 on the filter dirt box 11.

During use, the battery case of earlier two pieces of No. 5 AA batteries or rechargeable battery being packed into is opened the power supply of digital camera then, and screening-mode is made as M, and the focusing mode is made as MF.Then, unload camera lens, camera shutter speed is made as the B shelves, and press shutter.At this moment just can open the power supply 31 of the utility model deduster, allow the suction nozzle 4 of deduster vertically be close to the surface of image sensor CCD or CMOS, about back and forth gently wipe away the surface 1 to 3 time, the dust on image sensor surface just is eliminated.After cleaning was finished, the cameraman just can load onto camera lens, and with the alignment lens blank sheet of paper, the full width of cloth is taken a photo, to check the cleaning situation.

The utility model dust catcher aims at the dust of removing the image sensor surface and designs.This dust catcher can be finished the dedusting cleaning in 1-2 minute, its flexible suction nozzle can not scratch the image sensor surface.The utility model adopts No. 5 AA batteries or rechargeable battery powered, and volume is small and exquisite, and is economical and practical, carries use when being particularly suitable for location shooting and tourism shadow.
