Automatic winged insect and shielding prevention device for projector lens

Abstract

The invention relates to the technical field of multimedia equipment, and discloses an automatic winged insect and shielding prevention device for a projector lens. The device comprises a shell, a limiting plate is fixedly connected to the side face of the inner wall of the shell, a partition plate is inserted into the center of the interior of the limiting plate, and a bevel gear is rotatably connected to the side face of a bearing. A glass sheet is fixedly connected to the other end of a fixing frame, a glass brush is fixedly connected to the top of a sliding block, the glass sheet absorbs heat, mercury expands, a piston plate is pushed to move downwards, the bevel gear is driven to rotate, and through the reciprocating motion of the partition plate, a capacitor plate discharges periodically, a fan rotates periodically, the fan rotates, and insect expelling liquid in the liquid storage box is sucked out and is scattered around the projector lens to prevent flying insects from flyingto the lens to achieve the effect of automatic insect repelling, when the partition plate reciprocates, the sliding block drives the glass brush to repeatedly brush the surface of the glass sheet, andthe insect expelling liquid and dust are prevented from being attached to the glass sheet.

Description

technical field [0001] The invention relates to the technical field of multimedia equipment, in particular to an automatic anti-flying insect anti-blocking device for a projector lens. 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. During the development of projectors, white plastic screens, glass bead screens, metal screens and the fourth-generation projection screens with microcrystalline projection technology as the core have appeared, which continue to meet people's viewing needs. [0003] When the projector is in use, the lens often generates a lot of heat, which attracts a large number of flying insects to the lens. The overheated lens sometimes burns or even burns the flying insects. The flying insects will adhere to the lens, affecting the percep...
