Projection equipment with dustproof function and good heat dissipation effect

Abstract

The invention relates to projection equipment with a dustproof function and a good heat dissipation effect. The projection equipment comprises a main body and a projection lamp, and further comprisesa heat dissipation mechanism and a dustproof mechanism. The dustproof mechanism comprises a cover plate, a first bearing, a connecting shaft, a first gear and a driving assembly. The heat dissipationmechanism comprises a heat dissipation assembly, two filter screens and two cleaning assemblies. The heat dissipation assembly comprises a first motor, a rotating shaft, a second bearing, two transmission units and a plurality of blades. According to the projection equipment with a dustproof function and a good heat dissipation effect, through the dustproof mechanism, the projection lamp can be shielded, and the problem that dust adheres to the projection lamp to influence the projection effect when the equipment is idle is avoided; and through the heat dissipation mechanism, air circulation inside and outside the main body is accelerated, the heat dissipation effect is improved, and the problem that normal work of electronic elements in the main body is affected due to too high temperature in the main body is avoided.

Description

technical field [0001] The invention relates to the field of projection equipment, in particular to a projection equipment with dustproof function and good heat dissipation effect. 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] The projection lamp of the existing projector has been exposed to the outside, which increases the probability of dust adhering to the projection lamp and affects the projection effect of the projection lamp.

Problems solved by technology

[0003] The projection lamp of the existing projector has been exposed to the outside, which increases the probability of dust adhering to the projection lamp and affects the projection effect of the projection lamp. Not only that, but when the existing projector is performing projection work, the main body is prone to relatively large Too much heat, if the heat is not dissipated in time, it will easily affect the normal operation of the electronic components inside the main body and reduce the practicability of the projector
