Description
Technical field
The present invention relates to a kind of projecting apparatus, and in particular to dust-filtering system is shown in multifunctional visible meeting.
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.
In the prior art, after we lift projector, often only note the environment of surrounding, and forget hot-air rising
Problem, the projector worked on the ceiling, its environment temperature is generally greater than temperature below, the air that hot-air is increased
Flowing, 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 scattered
In hot systems, this will produce influence to projected picture.
Also, the polysilicon LCD panel used at present inside projecting apparatus is all to compare fearness high temperature, and newer type is in LCD panel
Temperature sensor nearby is equipped with, when air inlet and dirt filtrating screen are blocked, when air-flow is not smooth, at this moment temperature sensor can alarm simultaneously
Lamp source circuit is cut off immediately, and projector's internal temperature can also be raised rapidly, influence the optical property and service life of its camera lens.
So, the unimpeded of air inlet is kept, cleaning screen pack is very necessary in time.But projecting apparatus of the prior art only has
One simple dirt filtrating screen, holds dirt rate relatively low, it is therefore desirable to constantly or periodically clean the dirt filtrating screen of air inlet, bothers very much.
The content of the invention
Dust-filtering system is shown it is an object of the invention to provide multifunctional visible meeting, existing arm hanging type projector is solved
It is bad in the presence of radiating, the effect difference of dust is filtered, it is necessary to the problem of frequent clean dirt filtrating screen.
The present invention is achieved through the following technical solutions:
Dust-filtering system, including the rectangular frame being connected by arm with ceiling, the square are shown in multifunctional visible meeting
A projector body is placed with shape framework, a deep bead is additionally provided with rectangular frame bottom, the deep bead deviates from square
The side of shape framework caves inward to form arcwall face;The both sides of the projector body are also provided with ventilating opening, in projector body also
One filter dirt box body is installed, an end face of the dust filtration box body is generally aligned in the same plane with ventilating opening and communicated with ventilating opening,
Another end face is placed in projector body and is provided with least one ventilation port;Between the ventilating opening and ventilation port of filter dirt box body also
Dust bin is provided with, sponge gourd screen cloth, the circumferential direction and the inwall of filter dirt box body of the dust filtration cylinder are filled with dust bin
Match somebody with somebody, and the center line of dust bin is overlapped with filtering the center line of dirt box body;A wind is also respectively provided with the both sides of rectangular frame
Fan, the fan is symmetrical on the perpendicular bisector of two ventilating opening central point lines.
Further, to solve prior art problem, the present invention sets a deep bead in the bottom of rectangular frame, will kept off
The bottom of aerofoil is set to an arc groove shape, and so beneath hot-air is contacted after rising with the arcwall face of deep bead, so
Hot-air thus is avoided that projector body by the heat risen by the barrier effect arcuately oblique moved beneath in face of arcwall face afterwards
The influence of air.Meanwhile, in the embedded filter dirt box body in projector body both sides, extend air intake passage, compared to the prior art,
In the case of same air quantity, the structure can increase the contact area with air, air saturation be improved, 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, carried out by sponge gourd screen cloth
Filter, because sponge gourd screen cloth is porous ventilating structure, substantially increases appearance dirt rate, most small dust is in air-flow in air
By that can produce friction with sponge gourd screen cloth during the aperture of sponge gourd screen cloth and finally be stopped by the effect of electrostatic adsorption force under effect
Stay in sponge gourd screen cloth, the final dust particle for enter inside projector body is considerably less, improve filter dirt effect, it is to avoid
The problem of needing frequent clean dirt filtrating screen in the prior art.Fan positioned at rectangular frame both sides is carried out to blowing to ventilating opening, is had
Part air quantity can enter inside projector body, and the temperature of projector body is reduced with this, improve the problem of projector heat radiation is bad.
It is preferred that, the deep bead bottom is additionally provided with absorption film, and the absorption film is close to the setting of arcwall face surface.Enter one
Step, set absorption film to absorb the partial heat in ascending air on deep bead, hot-air pair is further reduced with this
The influence of projector body.
It is preferred that, it is also equipped with dirt filtrating screen on the ventilating opening.Dirt filtrating screen can tentatively be stopped to bulky grain grit.
The present invention compared with prior art, has the following advantages and advantages:
1st, multifunctional visible meeting projection dust-filtering system of the present invention, a deep bead is set in the bottom of rectangular frame, will
The bottom of deep bead is set to an arc groove shape, thus is avoided that projector body is influenceed by the hot-air risen;It is located at
The fan of rectangular frame both sides carries out, to blowing, having part air quantity to enter inside projector body, reducing projector to ventilating opening
The temperature of body, improves the problem of projector heat radiation is bad;
2nd, multifunctional visible meeting projection dust-filtering system of the present invention, in the embedded filter dirt box body in projector body both sides, prolongs
Air intake passage has been grown, then dust bin is set between the ventilating opening and ventilation port of filter dirt box body, air enters in dust bin, by silk
Melon screen 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, is kept away
The problem of having exempted to need frequent clean dirt filtrating screen in the prior art.
