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

[0013] Such as figure 1 , figure 2 and image 3 As shown, a projector dustproof system includes an exhaust wall 1 and a grid 2 .

[0014] There are a plurality of exhaust holes 10 on the exhaust wall 1 for exhausting the air after cooling the projector components.

[0015] The grid 2 is placed on the exhaust wall 1 , and a plurality of bosses 20 are arranged on the grid 2 , and the plurality of bosses 20 of the grid 2 correspond to the plurality of exhaust holes 10 on the exhaust wall 1 . The shape and size of the boss 20 and the vent hole 10 are the same, which is convenient for closing the vent hole 10, and ensures that the vent hole 10 can be opened and closed when the grid 2 is moved. Of course, the shape and size of the two can also be different, for example, the boss 20 is slightly smaller than the vent hole 10, so that the boss 20 can enter the vent hole 10 and close most of the vent holes 10. The shape of the grid 2 matches the shape of the exhaust holes 10 on the...

Abstract

The present invention relates to a dust-removing system of a projector, which comprises an air discharging wall, wherein a plurality of air discharging holes is arranged on the air discharging wall for discharging air in the projector. The dust-removing system of a projector with a grid also comprises the grid. The grid is arranged at the air discharging wall; a plurality of lug bosses is arranged on the grid; and the lug bosses enable the air discharging holes to communicate with the outside, or to seal the air discharging holes. In the dust-removing system of a projector, the lug bosses arearranged on the grid to enable the air discharging holes to communicate with the outside when the projector works, which does not affect the radiation and air discharging of the projector. When the projector stops working, the lug bosses on the grid are used for sealing the air discharging holes, which prevents dust from entering, the dust-removing ability of the projector is improved, and good dust-removing effect is reached.

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 ...
