Abstract
The utility model discloses an optics blank with fast dirt function of erasing, including optics blank body, optics blank body includes the display screen, fixed mounting has the frame on the display screen, T type spout has been seted up on the frame, and be provided with the T type slider rather than the looks adaptation in the T type spout, T type slider passes through screw fixedly connected with slide, it wipes to be provided with flexible cotton on the slide, and the outer surface contact with the display screen is wiped to flexible cotton, still be provided with on the frame and wipe corresponding air suction opening with flexible cotton, the dust catcher intercommunication that an air suction opening and frame side was equipped with, and the bottom of dust catcher is provided with the drain. This optics blank with fast dirt function of erasing can carry out quick effectual dust removal to the dust on the blank screen, can shield the blank in supratentorial dust sucks the dust catcher, avoids the dust to adsorb again on the blank screen to guaranteed the accuracy of optics blank location, prolonged its life, and can make its response speed become fast.
Description
Technical field
This utility model relates to optical whiteboard technical field, a kind of optical whiteboard with fast dust-erasing function.
Background technology
Interactive optical electronic whiteboard be one piece possess write, the electronic whiteboard of touch function, it it is again the computer display screen of an oversize simultaneously, electronic whiteboard is connected with each other with computer, digital projector three, and computer picture is projected to just constitute on blank a complete interactive demonstration system by projector.Relative to traditional blackboard and computer-aided instruction, its outstanding advantage is to can substitute for blackboard and curtain completely, directly carries out touching interactive operation.The interactive operation that touches of optical electron blank helps student to be turned to self-cooperation formula learn by original only reception learning by books, teacher and the head of a family, and learns to utilize multiple resources leap school enclosure wall to learn.Interactive electric whiteboard is current state-of-the-art Digital Teaching equipment, it is not only the integration of teacher's implementation information technology and course teaching and has built an exercisable application platform, also becomes student simultaneously and forms concept, exchanges the cognitive tool recognizing, showing learning outcome.
Interactive whiteboard infrared technology positioning principle is to be constituted scanning grid both horizontally and vertically by infrared receiver and the transmitting tube gathered in viewing area surrounding, form a plane of scanning motion net, when there being object to stop certain in grid to horizontal and vertical scan line, it is possible to determine that X, Y coordinate realize location by the infrared ray position both horizontally and vertically being blocked.But, this technology applies that to be affected ratio by dust on optical whiteboard more serious, if dedusting fast and effectively can not be carried out to carrying out whiteboard screen, can directly result in that its location is inaccurate, precision reduces, and service life shortens, and response speed is slack-off.
Utility model content
The purpose of this utility model is to provide a kind of optical whiteboard with fast dust-erasing function, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of optical whiteboard with fast dust-erasing function, including optical whiteboard body, described optical whiteboard body includes display screen, it is installed with frame on described display screen, T-shaped chute is offered on described frame, and it is provided with matched T-shaped slide block in T-shaped chute, described T-shaped slide block is fixedly connected with slide plate by screw, flexible cotton rub it is provided with on described slide plate, and flexible cotton rub contacts with the outer surface of display screen, the air suction opening corresponding with flexible cotton rub it is additionally provided with on described frame, the vacuum cleaner that described air suction opening is provided with frame one side connects, and the bottom of vacuum cleaner is provided with sewage draining exit.
Preferably, described air suction opening is spaced substantially equidistant the outer surface at frame.
Preferably, it is provided with wearing layer between described T-shaped chute and T-shaped slide block.
Preferably, described vacuum cleaner be internally provided with driving motor, and drive and in the rotating shaft of motor, be installed with blade.
Compared with prior art, the beneficial effects of the utility model are: by offering T-shaped chute on frame, T-shaped slide block it is provided with in T-shaped chute, T-shaped slide block is fixedly connected with slide plate by screw, flexible cotton rub it is provided with on slide plate, dust in whiteboard screen can be carried out dedusting fast and effectively, by being provided with the air suction opening corresponding with flexible cotton rub on frame, the vacuum cleaner that air suction opening is provided with frame one side connects, can the dust in whiteboard screen be sucked in vacuum cleaner, dust is avoided again to adsorb in whiteboard screen, thus ensure that the accuracy that optical whiteboard positions, extend its service life, and its response speed can be made to accelerate.
Accompanying drawing explanation
