Method for preventing temperature of projector projection port from being too high

Abstract

The invention provides equipment for preventing temperature of a projector projection port from being too high, and relates to the technical field of projectors. Supports are fixedly connected with four corners of the lower surface of a first shell; a base is rotatably connected with the outer surfaces of the supports on the front side of the lower surface of the first shell; a connecting column is rotatably connected with the inner side of the base; a bottom plate is fixedly connected with the lower surface of the base; a limiting plate is fixedly connected with the rear side of the upper surface of the bottom plate; and an elastic supporting rod is slidably connected with the rear surface of the connecting column in a penetrating mode. An air bag is compressed by thrust of the sliding plate; the air bag is deflated; the heat is discharged to the outer surface of a polaroid through a heat absorption pipe, and the polaroid is cooled; the polaroid can be cooled in time while the temperature of the polaroid rises; the effect that the service life of the polaroid is longer is guaranteed; the angle of the projector can be adjusted more conveniently; and the projector can be kept at different angles without the help of other auxiliary tools.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a method for preventing the temperature of a projection port of a projector from being too high. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are widely used in every aspect of our lives. Projectors can better meet our needs in daily life. At the same time, projectors also play a very important role in our work. [0003] However, the polarizer of the projector is relatively easy to damage. The projector controls the light waves absorbed by the polarizer by controlling the deflection of the liquid crystal screen during projection. The more light waves absorbed by the polarizer, the higher the temperature of the polarizer itself. Working under ...

Problems solved by technology

[0003] However, the polarizer of the projector is relatively easy to damage. The projector controls the light waves absorbed by the polarizer by controlling the deflection of the liquid crystal screen during projection. The more light waves absorbed by the polarizer, the higher the temperature of the polarizer itself. Working under the condition of high temperature for a long time, the service life of the polarizer will decrease faster. Therefore, those skilled in the art have provided equipment and methods for preventing the temperature of the projection port of the projector from being too high to solve the problems in the above-mentioned background technology. proposed question
