Description
[technical field]
The utility model is about a kind of projection arrangement, and particularly about a kind of projection arrangement that is used for the protection network of projection arrangement and has protection network.
[background technology]
Projection arrangement can produce the element of high heat because of having lamp source etc., thus need dispel the heat by fan, too high and damage to avoid projection arrangement Yin Wendu.Generally speaking, the housing of projection arrangement is provided with air intake vent and air outlet, and during fan running in being arranged at housing, extraneous cold air can enter in the housing via air intake vent, and can discharge via air outlet outside the housing at the hot-air of enclosure interior, so can reach the purpose of heat radiation.
Yet, scattering many micronic dusts in the air, these micronic dusts enter in the housing of projection arrangement along with air easily, and are deposited in the element of enclosure interior, as fan, image processing wafer, eyeglass or other optical elements etc.In addition, when projection arrangement turned round, the lamp source can be luminous, so cause having phototactic mosquito easily, worm flies into enclosure interior via the air intake vent of housing.When the element of enclosure interior is accumulated the corpse of too much micronic dust or mosquito, worm, will produce harmful effect to display quality, light utilization ratio and the radiating efficiency etc. of projection arrangement, even cause projection arrangement to damage.
Based on above-mentioned, TaiWan, China is announced the I226485 patent and has been proposed a kind of dust guard that is used for projection arrangement, is located at the enclosure interior of projection arrangement, accumulates too much micronic dust to prevent particular element.Yet,, clean the shortcoming that is difficult for so have because this dust guard is located at enclosure interior.In addition, this dust guard only can be used to protect particular element, and can't protect all elements of enclosure interior.
In addition, TaiWan, China is announced the projection arrangement that the I233528 patent has proposed to have air filter, as Fig. 1 and shown in Figure 2.The air filter 150 of this projection arrangement 100 is located in the housing 110, and comprises storage tank 160, filter screen 170 and anchor clamps 180.Storage tank 160 is located in the housing 110, and anchor clamps 180 are in order to clamping filter screen 170.Anchor clamps 180 and can take out in storage tank 160 slidably to storage tank 160, so that change filter screen 170 or clean filter screen 170.
Yet,, cause the production cost of existing projection arrangement 100 higher because the mechanism of above-mentioned air filter 150 is comparatively complicated.In addition, may not be located at same sidewall, cause needing to use several air filters 150, so will further increase the production cost of existing projection arrangement 100 because of the air outlet and the air intake vent of housing 110.
