Projector with dust removal function

Abstract

The invention relates to a projector with a dust removal function. The projector comprises a main body, a filter screen and a lens, and further comprises a dust removal mechanism and a cleaning mechanism, wherein the dust removal mechanism comprises a fixed box, a dust removal plate, a movable box, a movable assembly, a first connecting pipe, a second connecting pipe, a collecting box, an impurity removal net, an air suction assembly, an auxiliary assembly, two air cylinders and a plurality of suction nozzles; and the cleaning mechanism comprises a cleaning box, a third bearing, a second lead screw, a ball screw bearing, a connecting block, a scraper, a limiting plate and two fixing rods. According to the projector with the dust removal function, through the dust removal mechanism, the function of removing dust from the lens is achieved, the situation that the dust covers the lens and accordingly projection work is affected is avoided, and therefore the reliability of the projector is improved; and through the cleaning mechanism, the function of dust removal of the filter screen is achieved, the probability of blockage of the filter screen is reduced, and the influence on heat dissipation work is avoided.

Description

technical field [0001] The invention relates to the field of office equipment, in particular to a projector with a dust removal function. 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 currently widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. [0003] Existing projectors generally use a filter to circulate the air inside the main body, so as to realize the heat dissipation function. After long-term use, the filter is easily blocked by dust, which affects the circulation of the air, thereby affecting the heat dissipation work, not only that , the lens of the existing projector is usually exposed outside without a blocking device, ...

Problems solved by technology

[0003] Existing projectors generally use a filter to circulate the air inside the main body, so as to realize the heat dissipation function. After long-term use, the filter is easily blocked by dust, which affects the circulation of the air, thereby affecting the heat dissipation work, not only that , the lens of the existing projector is usually exposed outside without a blocking device, so that the dust in the air can easily cover the lens, which will block the line of sight of the lens and affect the projection work, thereby reducing the reliability of the existing projector sex
