Description
Technical field
The present invention relates to a kind of projecting apparatus, and in particular to the projection structure with efficient anti-gray function.
Background technology
Projecting apparatus is also known as projector, is by image or video by digital optical processing technique or LCD liquid crystal imagings technology
The equipment for projecting or reflexing on screen, can be by different signal sources, and such as computer, mobile phone, DVD, DV access are corresponding
Image and vision signal, realize and play.Projecting apparatus is widely used in the places such as education, commercial affairs, engineering, family expenses.
Typically only 1.3 inches of the polysilicon LCD panel used at present inside projecting apparatus, even only 0.9 inch had, and
Resolution ratio reaches 1024X768 or 800X600, that is to say, that the dust granule that each pixel only has 0.02mm enough stops it.
And there is special fan to be sent with the flow of tens litres of air per minute to it because projector's LCD panel fully radiates typically
Air cooling, high velocity air is after dirt filtrating screen it is also possible to entrainment small dust, they, which mutually rub, produces electrostatic and be adsorbed in
In cooling system, this will produce influence to projected picture.Therefore, it is dust-proof extremely important in projector's use environment, must
Absolutely no smoking, because smokeshade is easier absorption in optical system.
The simple dirt filtrating screen of projecting apparatus only one of which of the prior art, holds dirt rate relatively low, it is therefore desirable to constantly or periodically
The dirt filtrating screen of air inlet is cleaned, is bothered very much.
The content of the invention
It is an object of the invention to provide the projection structure with efficient anti-gray function, solve existing projecting apparatus and cross leaching
The effect of dirt is poor, holds dirt rate low, it is necessary to the problem of frequent clean dirt filtrating screen.
The present invention is achieved through the following technical solutions:
Projection structure with efficient anti-gray function, including projector body, the both sides of the projector body have one
Individual ventilating opening, is also equipped with a filter dirt box body in projector body, and an end face of the dust filtration box body is located at ventilating opening
Same plane and communicated with ventilating opening, another end face is placed in projector body and is provided with least one ventilation port;In filter dirt box
Dust bin is additionally provided between the ventilating opening and ventilation port of body, sponge gourd screen cloth, the week of the dust filtration cylinder are filled with dust bin
Matched to direction with filtering the inwall of dirt box body, and the center line of dust bin is overlapped with filtering the center line of dirt box body.
Further, the present invention devises a kind of new projector architecture, in the embedded filter dirt box in projector body both sides
Body, extends air intake passage, compared to the prior art, in the case of same air quantity, the structure can increase the contact surface with air
Product, improves air saturation, so as to put forward High dust holding rate.Dust bin is set between the ventilating opening and ventilation port of filter dirt box body again,
Air enters in dust bin, is filtered by sponge gourd screen cloth, because sponge gourd screen cloth is porous ventilating structure, substantially increases appearance
It can produce and rub with sponge gourd screen cloth when most small dust passes through the aperture of sponge gourd screen cloth under airflow function in dirt rate, air
Wipe and eventually settled at by the effect of electrostatic adsorption force in sponge gourd screen cloth, the final dust for enter inside projector body
Particulate is considerably less, improves filter dirt effect, it is to avoid the problem of needing frequent clean dirt filtrating screen in the prior art.
It is preferred that, it is also equipped with dirt filtrating screen on the ventilation port.Dirt filtrating screen is installed on ventilation port can be further to entering
Air inside projector body is filtered.
It is preferred that, the gap formed between several ventilative blades, adjacent ventilative blade is also equipped with ventilating opening
Center line and the lower surface of projector body be mutually perpendicular to.Further, earth's surface heat energy can rise with the flowing of air, will
The slit design formed between adjacent ventilative blade is the orthogonal form of lower surface with projector body, can make projector
The heat that body itself is distributed rises under the active force of the hot-air of rising, is conducive to improving radiating effect.
The present invention compared with prior art, has the following advantages and advantages:
The present invention has the projection structure of efficient anti-gray function, in the embedded filter dirt box body in projector body both sides, extension
Air intake passage, then dust bin is set between the ventilating opening and ventilation port of filter dirt box body, air enters in dust bin, by sponge gourd net
Cloth is filtered;Above structure, which is substantially increased, to be held dirt rate, improves filter dirt effect and the service life of projector body, it is to avoid
The problem of needing frequent clean dirt filtrating screen in the prior art.

Embodiment
As shown in Figure 1, 2, the present invention has the projection structure of efficient anti-gray function, including projector body 1, the projector
The both sides of body 1 have a ventilating opening 2, and a filter dirt box body 3, the dust filtration box body 3 are also equipped with projector body 1
An end face be generally aligned in the same plane and communicated with ventilating opening 2 with ventilating opening 2, another end face is placed in projector body 1 and opened
There is at least one ventilation port 4;Dust bin 5 is additionally provided between the ventilating opening 2 and ventilation port 4 of filter dirt box body 3, in dust bin 5
Interior to be filled with sponge gourd screen cloth, the circumferential direction of the dust filtration cylinder 5 is matched with filtering the inwall of dirt box body 3, and the center line of dust bin 5
Overlapped with the center line for filtering dirt box body 3.Dirt filtrating screen 6 is also equipped with the ventilation port 4.It is also equipped with ventilating opening 2 some
The lower surface of the center line and projector body 1 in the gap formed between individual ventilative blade 7, adjacent ventilative blade 7 is mutually perpendicular to.
Projector's LCD panel fully radiates, and general to have special fan to carry out air-supply to it with the flow of tens litres of air per minute cold
But, with the flowing of cooling air-flow, the sponge gourd net that most dust particle passes through in dust bin 5 under airflow function in air
Cloth, sponge gourd screen cloth produces frictional force and electrostatic adsorption force to dust particle so that dust particle is finally adsorbed in sponge gourd screen cloth.
The effect that above structure solves existing projecting apparatus filtering dust is poor, and appearance dirt rate is low, it is necessary to the problem of frequent clean dirt filtrating screen.
Above-described embodiment, has been carried out further to the purpose of the present invention, technical scheme and beneficial effect
