Problems solved by technology

Based on the principle of projector imaging, there should be very little dust in the environment when the projector is working, otherwise it will pollute the optical machine and affect the imaging effect. Dust will also cause the temperature of the internal electronic components to rise, resulting in failures and even burnout of the components.
[0003] Generally, the projector will be equipped with a dust-proof system on the air intake side to ensure that the air cooling the light machine is filtered to protect the light machine, while the exhaust side is rarely protected, but the projector is often installed directly in the conference If the projector is not cleaned for a long time, a lot of dust will float into the projector from the exhaust side when the projector is not in use, and it will pollute the inside of the projector after a long time, resulting in poor dustproof effect of the projector.

Embodiment Construction

[0024] figure 1 , figure 2 and image 3 The structure schematic diagram of the projector dustproof system is shown, and the projector dustproof system includes a shutter 1 and a projector exhaust wall 2 .

[0025] The louver 1 is arranged at the exhaust wall 2 of the projector. The louver 1 includes a plurality of blades 10, which are placed side by side and can be opened or closed individually or together, and there is no gap or a small gap between adjacent blades when the plurality of blades are closed. A plurality of blades 10 are arranged on the exhaust wall 2 of the projector, so as to make the exhaust hole of the projector communicate with the outside for heat dissipation or to close the exhaust hole of the projector to prevent dust from entering. When the projector is working, the multiple blades 10 of the shutter 1 are opened together to ensure the exhaust and heat dissipation of the projector. When the projector stops working, the multiple blades 10 of the shutter...

Abstract

The invention relates to a shutter projector dustproof system which comprises a projector exhaust wall. The shutter projector dustproof system also comprises a shutter, wherein the shutter is arranged at the projector exhaust wall to enable an exhaust hole of a projector to be communicated with the outside or close the exhaust hole of the projector for preventing dust from entering. The shutter projector dustproof system enables the shutter to be arranged on a casing at the exhaust side of the projector; when the projector works, the shutter is moved to enable the exhaust hole to be communicated with the outside so as to ensure the projector radiates heat; and when the projectors stops working, the shutter is closed, the dust is prevented from entering, thereby improving the dustproof property of the projector and achieving better dustproof effect.

Description

【Technical field】 [0001] The invention relates to a projection equipment system, in particular to a dustproof system for a projector. 【Background technique】 [0002] With the development of technology, projectors are becoming more and more popular. Based on the principle of projector imaging, there should be very little dust in the environment when the projector is working, otherwise it will pollute the optical machine and affect the imaging effect. Dust will also cause the temperature of the internal electronic components to rise, cause malfunctions, and even cause components to burn out. [0003] Generally, the projector will be equipped with a dust-proof system on the air intake side to ensure that the air cooling the light machine is filtered to protect the light machine, while the exhaust side is rarely protected, but the projector is often installed directly in the conference If the projector is not cleaned for a long time, a lot of dust will float into the projector ...
