Projection equipment with dustproof function

Abstract

The invention relates to projection equipment with a dustproof function. The projection equipment comprises a main body, a filter screen, a lens, a dustproof mechanism and a dust removal mechanism, wherein the dustproof mechanism comprises a driving assembly, a fixing frame and two dustproof assemblies; and the dust removal mechanism comprises a first bearing, a transmission shaft, a first bevel gear, a second bevel gear, two scraping plates, two knocking assemblies and a plurality of convex blocks. The projection equipment with the dustproof function realizes a function of shielding a lens through the dustproof mechanism, so that the lens cannot be exposed in the air, dust cannot cover the lens, therefore, the dustproof function is achieved, the projection effect is prevented from being affected by dust coverage, the reliability of the equipment is improved, the dust removal function of the filter screen is achieved through the dust removal mechanism, and the phenomenon that air circulation of the equipment is affected due to filter screen blockage is avoided.

Description

technical field [0001] The invention relates to the field of photoelectric equipment, in particular to a projection equipment with dustproof 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. [0003] When the existing projection equipment is in use, because the lens is always exposed to the air, the dust in the air can easily cover the lens, thereby affecting the projection work. Not only that, the existing projection equipment is easy to accumulate on the filter after long-term use Excessive dust will cause the filter holes to be blocked, affecting the air circulation inside and outside the main body, thus affecting the heat dissipation of the main body, thus increasing the probability of damage to the electronic components inside the main body d...
