Description

Electrostatic precipitation camera

Technical field

The present invention relates to a kind of cameras, are a kind of cameras for facilitating and removing camera lens dust particularly.

Background technique

Video camera includes lens group, darkroom, image forming medium and imaging control structure, is a kind of more accurate instrument, It needs carefully to protect in use；But the dust in air is ubiquitous, easily enters in use tiny Dust；When dust is adhered to camera lens surface, the imaging of camera lens will affect, so that photograph generates blackening；If clear not in time Reason is easy to aggravate the abrasion of camera lens, or even causes the stuck of camera components, and the injury for being difficult to repair is caused to camera；Meanwhile mirror The surface of head is coated with coating, needs touching, cleaning gently, due to secreting grease on finger skin, cannot pass through in cleaning Finger is directly touched, it is often necessary to dedicated air-blowing or cleaning brush, therefore cleaning needs to spend more time；If it is Occurring the case where dust adherency in normal photographing, photographer has to stop working normally and clearing up camera lens, this When will seriously affect shooting work and be normally carried out.

Summary of the invention

In view of the above-mentioned problems, the present invention provides a kind of electrostatic precipitation camera, the electrostatic precipitation camera structure is novel, principle is only Spy, it is easy to operate, quick, can effectively shorten the deashing time, fast quick-recovery camera lens it is bright and clean, clean.

To solve the above problems, the technical scheme adopted by the invention is that: the electrostatic precipitation camera includes the sheet of camera Body is removably provided with lens case on the camera lens of the ontology；

The lens case includes can be with the cover of shots match, and sliding is provided with piston frame, the work in the cover The sliding contact that the inner sidewall of the lateral wall and cover of filling in frame fits closely；

The internal slide of the piston frame is provided with piston plate, the inner sidewall of piston frame is provided with volatile electronic friction layer, The lateral wall of piston plate is provided with the electronic friction layer that is easy to get；The lateral wall of the piston plate and the inner sidewall of piston frame closely paste The sliding contact of conjunction；

In the lower surface array arrangement spray point of the piston plate, the spray point connects with the electronic friction layer electrical communication that be easy to get Touching；The lower surface of the piston frame lower plate is provided with static board, the static board connects with volatile electronic friction layer electrical communication Touching；It offers in the lower plate of the piston frame and static board and exists with the matched insulated vias of spray point face, spray point The contact of Shi Buyu static board is moved back and forth in insulated vias；

Pulley blocks are provided on the top plate of the cover, traction rope is installed in the pulley blocks, the one of the traction rope End is fixed on piston frame, and the other end is fixed on piston plate after passing through piston frame；In piston frame upper plate and the upper table of piston plate Reset tension spring is provided between face,

It is additionally provided with catch bar in the upper surface of the piston plate, the end of the catch bar is outside after piston frame and cover Expose；When pressing catch bar repeatedly, the piston frame, piston plate can be above and below the axis under the gearing of traction rope, along cover It reciprocatingly slides；When piston frame or piston plate slide down to extreme position, the mirror of corresponding static board or spray point close to camera lens Piece；

Be also provided with matched gas port in opposite side plate lower part contact of cover and piston frame, cover on piston frame side plate When gas port face, it is connected to inside cover with outside air.

The beneficial effects of the present invention are: only lens case cover need to be set anti-on camera lens when the camera lens of camera needs to clear up Catch bar, piston plate sliding friction opposite with piston frame, then in electronic friction layer and the volatile electronic friction layer of being easy to get are pressed again Between realize the transfer of electrostatic charge, which is transferred on corresponding static board and spray point, during pressing repeatedly, puts Acusector accumulates negative electrical charge, and static board accumulates positive charge；

When catch bar drives piston plate to move down, traction rope band piston frame is moved up, the reset tension spring between piston frame and piston plate Elongation；Spray point passes through from insulated vias and moves closer to eyeglass, ash of the negative charge transport on spray point to camera lens surface On dirt, so that dust carries negative electricity；When shedding the active force of catch bar, reset tension spring rebound, then piston plate, piston frame are anti- To movement, the static board on piston frame under the action of Electrostatic Absorption, is taken electronegative dust and is carried just gradually close to eyeglass The static board absorption of electricity, then completes cleaning, the dedusting to eyeglass.

In use, catch bar only need to be pressed repeatedly, it can be in the case where not wearing camera lens, effectively by camera lens The dust on surface, which adsorbs, to be removed；Meanwhile when pressing catch bar repeatedly, the intracorporal air of the suction hood of piston plate repeatedly, every time Gas is discharged from gas port when depressing catch bar, and ambient atmos enter cover and brush camera lens surface when catch bar is sprung back, thus Play the effect of air-blowing.

To sum up, without carrying burnisher when using this camera, lens case can when storing camera effective protection mirror Head, again being capable of convenient deashing when dust occurs in camera lens；Operating method and its simplicity simultaneously only need to press catch bar repeatedly, The economic benefits and social benefits dedusting that can realize air-blowing, electrostatic effectively improves efficiency of dust collection, shortens the camera lens deashing time, to facilitate user's It uses.

Preferably, the electronic friction layer that is easy to get is silk layer, volatile electronic friction layer is glassy layer；The material can It effectively reduces cost, while conveniently generating larger electrostatic during piston frame, piston plate are with respect to sliding friction.

Preferably, the electronic friction layer that is easy to get is rubber layer, volatile electronic friction layer is trichocutis；The material can It effectively reduces cost, while conveniently generating larger electrostatic during piston frame, piston plate are with respect to sliding friction.

Preferably, 10 ° of direction eyeglasses of the air guide hole deviation；In order to enhance the effect of air-blowing.

Preferably, being provided with limit spring between the upper plate of the cover and piston frame；In order to keep traction rope In exceptionally straight state, to avoid the shaking of piston frame.
