SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough that the easy dust that blocks of current projecting apparatus air intake, the utility model provides a projecting apparatus cooling dust cover, this dust cover not only can prevent dust, still has the refrigerated effect of heat dissipation, can improve the life of projecting apparatus greatly.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a projecting apparatus cooling dust cover, contains the mounting panel with projecting apparatus air intake adaptation, the mounting panel lateral part is installed the dust cover and is constituteed cavity structures, cavity structures internally mounted has the fan, cavity structures's entrance point is provided with the filter screen.
According to another embodiment of the present invention, further comprising, the fan is fixed on the mounting plate by a fan spacer. The fan cushion blocks are heightened to enable the air fluidity of the fan to be better, and therefore the flowing of air flow and the dissipation of heat are facilitated.
According to the utility model discloses a further embodiment, further include, the filter screen is supported through inboard filter screen support. The filter screen support prevents the filter screen from collapsing and collapsing.
According to the utility model discloses a further embodiment, further include, it is fixed through the front shroud outside the filter screen, the front shroud links to each other with filter screen support draw-in groove, front shroud fixed connection is at cavity structures's entrance point. The filter screen and the filter screen bracket are clamped and embedded between the front cover plate and the inlet end of the cavity structure, so that the filter screen is convenient to replace.
According to another embodiment of the present invention, further comprising, the dust cover side portion is connected to the projector through an angle iron mounting bracket. The installation and the disassembly are more convenient, and the connection strength can be ensured.
According to the utility model discloses a further embodiment, further include, the junction of projecting apparatus air intake and mounting panel is provided with the sponge strip. The sponge strip plays the effect of filtering and keeping off the dust, avoids the dust to get into from connecting the gap.
The utility model has the advantages that the filter screen outside the cavity structure can prevent dust from entering, and the fan inside the cavity structure can facilitate the heat emission, so that the cooling dust cover of the projector can simultaneously obtain the cooling and dust-proof effects, and meanwhile, the air flow formed by the fan inside can blow away the dust, so that the dust-proof effect is better, and the service life of the projector is greatly prolonged; through fixing the entrance point at cavity structures with the front shroud, form the accommodation space of filter screen and support, the change of the filter screen of being convenient for, this application has simple structure, uses convenient and dustproof cooling effect's good advantage.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a perspective view of the present invention;
fig. 2 is a partial cross-sectional view of the present invention;
fig. 3 is a front view of the present invention;
fig. 4 is a schematic view of the present invention assembled on a projector.
In the figure, the projector 1, the projector 2, the mounting plate 3, the dust cover 4, the cavity structure 5, the fan 6, the filter screen 7, the fan cushion block 8, the filter screen support 9, the front cover plate 10, the angle steel mounting support 11 and the sponge strip.
Detailed Description
Fig. 1 to 3 are structural schematic diagrams of the present invention, and a projector cooling dust cover comprises a mounting plate 2 adapted to an air inlet of a projector 1, wherein a dust cover 3 is mounted on a side portion of the mounting plate 2 to form a cavity structure 4, a fan 5 is mounted inside the cavity structure 4, and a filter screen 6 is arranged at an inlet end of the cavity structure 4.
In this application, mounting panel 2, dust cover 3, filter screen 6 form the inlet air duct of projecting apparatus 1, and filter screen 6 in the cavity 4 outside can prevent the dust entering, and cavity 4 inside fan 5 can be convenient for thermal giving off to obtain cooling, dustproof effect simultaneously, the air current that 5 forms of inside fan simultaneously also can blow away the dust, and dustproof effect is better, improves the life-span of projecting apparatus greatly. In this application, mounting panel 2, dust cover 3, fan 5, filter screen 6 all adopt the material of matter light to alleviate the whole weight of projecting apparatus cooling dust cover.
According to another embodiment of the present invention, further comprising, the fan 5 is fixed on the mounting plate 2 by a fan spacer 7. The fan cushion block 7 is heightened to enable the air of the fan 5 to have better fluidity, so that the flowing of air flow and the heat dissipation are facilitated.
According to another embodiment of the present invention, further comprising, the filter screen 6 is supported by the filter screen support 8 of the inner side. The filter screen 6 can be fixed on the filter screen support 8 in a sticking mode, and the filter screen support 8 prevents the filter screen 6 from collapsing.
