The working principle is as follows: when the projection device 2 works, the motor 12 is turned on and the metal plate 14 and the first spring 16 are electrified, so that an electric field is generated near the metal plate 14, a heterogeneous charge appears at one end of a light object close to the light object, and an equivalent homogeneous charge appears at one end of the light object far from the light object, because the dust is a light object, when the dust enters through the first air inlet 19, most of the dust is filtered through the filter layer arranged at the first air inlet 19, then a small amount of the dust entering the projection device 2 is adsorbed through the metal plate 14, the passing capacity of the metal plate 14 is adjusted by increasing the capacity, so that the dust adsorption efficiency is ensured, the dust is adsorbed, the first spring 16 contracts, the rotating shaft 10, the second gear 9, the first gear 8 and the inserted link 5 are driven to rotate by the motor 12, and the heat absorbed by the heat conduction plate 3 is discharged through the air outlet 20 by the fan blades 11, thereby dissipating heat from the projection apparatus 2, then the first magnet 17 drives the second magnet 18 to rotate through magnetism, thereby rotating the first sleeve 6, and further causing the first sleeve 6 to drive the stirring blade 7 to stir the cooling liquid, thereby increasing the heat absorption speed of the cooling liquid, when the projection apparatus 2 finishes working, the metal plate 14 and the first spring 16 are powered off, the first spring 16 is powered off to rebound, thereby driving the cleaning plate 15 to clean dust adsorbed on the surface of the metal plate 14, by arranging the chemical fiber layer at the bottom of the cleaning plate 15, since the static electricity of the fiber is large, dust is easily adsorbed when moving, when the first spring 16 rebounds, part of dust is adsorbed through the chemical fiber layer, when the first spring 16 rebounds to the inside of the top opening of the dust collection box 21, the cleaning plate 15 stops moving and generates certain impact, so that the dust falls into the dust box 21 by shaking, the chemical fiber layer is located inside the dust box 21 to prevent the dust from flying, thereby collecting the dust after the dust is collected, and further collecting the dust inside the dust box 21, thereby collecting the dust inside the dust box 21, when the projection device 2 works, the electromagnet 26 is electrified and magnetized through the controller 13, so that the electromagnet 26 attracts the third magnet 27 through magnetic force, thereby enabling the third magnet 27 to drive one end of the elastic airbag 28 to move, when the elastic airbag 28 moves, the external air is extracted through the first one-way valve 29, when the controller 13 cancels the electrification of the electromagnet 26, the elastic airbag 28 rebounds, the elastic airbag 28 ejects the extracted air through the second one-way valve 30, the air enters the air outlet disc 32 along the air outlet pipe 31, and then the dust on the surface of the lens 24 is removed, thereby the clear burden of manual work has been reduced, when projection arrangement 2 was out of work, through pressing down the pressure piece 37 for press the piece 37 to drive second spring 36 and remove, tensile dust guard 34 when the locating lever 38 top is less than the level of dust guard 34 bottom, when locating slot 39 bottom is located the locating lever 38 directly over, unclamp the pressing to pressing the piece 37, make second spring 36 kick-back carry on spacingly to dust guard 34, thereby prevent that the dust from falling into first air intake 19 top.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
