Description
Technical field
This utility model is projector curtain dust arrester, is to design for the curtain automated cleaning of projector, belongs to
Environmental area.
Background technology
Multimedia is many, and the curtain of projector is the most, and projector curtain is hung the equipment of use all the year round, and few people will
Projector curtain is unpicked and washed, and so, projector curtain the most all can accumulate a lot of dust；The accumulation of dust causes study, work
Making the deterioration of environment, for the personnel under this study, working environment all the year round, health to be affected by certain；This reality
With the projector curtain dust arrester of novel offer, these problems can be solved.
Utility model content
The specific practice of this programme is: uses projector curtain dust arrester as shown in Figure 1 and Figure 2, can collect throwing in time
Dust on shadow instrument cloth curtain；Projector curtain dust arrester is by vacuum cleaner 1, electrostatic felt 2, screen curtain 3, screen folding and unfolding facility
4 with lower axle 5 composition；Vacuum cleaner 1 is suspended on the surface of screen curtain 3, with screen curtain 3 vis-a-vis；Electrostatic felt 2 is being inhaled
The lower section of dirt device 1, consolidates with the bottom of vacuum cleaner 1, presses close to contact with screen curtain 3；Screen folding and unfolding facility 4 is with lower axle 5 respectively
It is arranged on surface and the underface of screen curtain 3.
Vacuum cleaner 1 includes dust shield, sweep-up pipe, negative pressure generator, dust delivering tube, ash deposition box several device；Dust shield is installed
Above projector curtain, and projector curtain vis-a-vis, when projector curtain moves up and down under external force,
Having to pass through dust shield, under the effect of negative pressure generator, the dust on projector curtain will be adsorbed, into dust shield, passing through
Sweep-up pipe, ash pipeline, enter ash deposition box；
Electrostatic felt 2 is the felt base part of static electrification, is fixedly arranged at the lower section of the dust shield of vacuum cleaner 1, tight with projector curtain
Patch；The floating ash do not collected by vacuum cleaner 1, under the adsorption of electrostatic, is adsorbed on its surface by electrostatic felt 2.
Screen curtain 3 is the curtain playing projection, and top consolidates with screen folding and unfolding facility 4, and bottom consolidates with lower axle 5；?
Under the effect of screen folding and unfolding facility 4, screen curtain 3 can move up and down.
Screen folding and unfolding facility 4 is the actuating unit of folding and unfolding screen curtain 3, when accepting " packing up " or " transferring " instruction, and energy
Screen curtain 3 is packed up or put down.
Lower axle 5 is fixedly arranged at the bottom of screen curtain 3, and screen curtain 3 is applied certain gravity, makes screen curtain 3 all the time
Vertically downward.
The beneficial effects of the utility model are to make projector curtain just can be made projector by automated cleaning during folding and unfolding
Curtain is in clean, sanitary state all the time.

Detailed description of the invention
Embodiment
Certain office uses projector curtain dust arrester as shown in Figure 1 and Figure 2, can collect in time on projector cloth curtain
Dust；Projector curtain dust arrester is by vacuum cleaner 1, electrostatic felt 2, screen curtain 3, screen folding and unfolding facility 4 and 5 groups of lower axle
Become；Vacuum cleaner 1 is suspended on the surface of screen curtain 3, with screen curtain 3 vis-a-vis；Electrostatic felt 2 is vacuum cleaner 1 time
Side, consolidates with the bottom of vacuum cleaner 1, presses close to contact with screen curtain 3；Screen folding and unfolding facility 4 and lower axle 5 are separately positioned on screen
The surface of curtain 3 and underface.
Vacuum cleaner 1 includes dust shield, sweep-up pipe, negative pressure generator, dust delivering tube, ash deposition box several device；Dust shield is installed
Above projector curtain, and projector curtain vis-a-vis, when projector curtain moves up and down under external force,
Having to pass through dust shield, under the effect of negative pressure generator, the dust on projector curtain will be adsorbed, into dust shield, passing through
Sweep-up pipe, ash pipeline, enter ash deposition box；
Electrostatic felt 2 is the felt base part of static electrification, is fixedly arranged at the lower section of the dust shield of vacuum cleaner 1, tight with projector curtain
Patch；The floating ash do not collected by vacuum cleaner 1, under the adsorption of electrostatic, is adsorbed on its surface by electrostatic felt 2.
Screen curtain 3 is the curtain playing projection, and top consolidates with screen folding and unfolding facility 4, and bottom consolidates with lower axle 5；?
Under the effect of screen folding and unfolding facility 4, screen curtain 3 can move up and down.
Screen folding and unfolding facility 4 is the actuating unit of folding and unfolding screen curtain 3, when accepting " packing up " or " transferring " instruction, and energy
Screen curtain 3 is packed up or put down.
Lower axle 5 is fixedly arranged at the bottom of screen curtain 3, and screen curtain 3 is applied certain gravity, makes screen curtain 3 all the time
Vertically downward.
