Projector regards a kind of accurate electron as the product, technology of circuit of its market mechanism, liquid crystal and DMD, electron at an organic whole, rely on optical system to become picture. Stem from medicinal powder hot consideration, there are groove or mouth to be used at commonly on the housing of projector ventilated, high speed air current is probable notes smuggled into an examination hall is small grit, these atomic probable adsorption are on liquid crystal board and the influence is become picture. Have again, present environment pollutes northern region of serious with each passing day, our country to return the question with existence big sand blown by wind, even if indoors, the object that is put in air can adhere to very quickly a dust. Because this projector is using the hard to avoid in the process,can appear more into the dirt, circumstance that enter ash. If clear when user adventitious, projector intake is very easy by block, hot air cannot eduction, projector interior component is easy by burn down. Prevent so dirt comes loose together heat is euqally important, practice proves fixed light road removes dust is the good method with a practical economy that prolongs service life, and the product that has advantageous and dustproof design is met get twice the result with half the effort.
Be aimed at educational environment technically and projector of series of the PT-PX98 /PX95/PS95 below the pine is used, outside teaching the use environment of projector to decide projector removes the effect that suffers general environment dust, return the influence of existence dust. Accordingly, the projector below the pine that had technology of completely dustproof and airtight type becomes the central issue of the industry suddenly. Of this technology original creation add before projector camera lens installed seal cover, can of the oldest rate prevent dirt to enter projector airframe, and use new-style dirt screen pack, make dustproof effect more outstanding, reflected a pine adequately to issue this series projector with " education is this " design concept, this also is the special education type that projector manufacturer faces China to teach the market to roll out first.
The series below the pine taught projector to basically highlight dustproof effect from 3 respects, above all this series model used new dustproof box design, the on half part of whole box is mixed for an organic whole, the reduced dirt to enter machine interior through box juncture possibility of utmost. And the unique design of interface board was to avoid more before projector interface place is completely bare the malady in the environment, reduced dirt to pass the possibility that interface board enters likewise. Next they use has improved new-style screen pack entirely, this kind of new-style screen pack slam the door the design of screen pack of traditional before monolayer, use design of double deck mesh however. Ground floor filters dust of airy big grain, the 2nd is filtering petty grain. And new mesh all used new-style data, lowered dirt minimum to the harm of projector. Still have installed cover of new-style and dustproof camera lens: Pass the cover of dustproof camera lens that designs technically, the camera lens that makes adjust good is encapsulated situation, prevented dirt to enter, also avoided a non-professional to be opposite because of what be operated by accident and cause the harm of camera lens. Although added shade of a camera lens, but any distinction are done not have with common projector on indication effect.
