The invention can be illustrated by the following operating modes: when dust adheres to the screen of the display screen 7, the fan 5 can be started at this time, and the starting of the fan 5 causes the placing groove 2 → the hollow plate 3 located above → the filter chamber 8 → the fan 5 → the hollow plate 3 located below → the air in the placing groove 2 to flow, so that the dust on the screen is blown off, and then enters the filter chamber 8 through the air flow, so that the dust is adsorbed on the filter screen 9 located above;
when dust is adsorbed to a certain degree on the upper filter screen 9, the dust can block meshes on the filter screen 9, then under the operation of the fan 5, negative pressure is generated below the upper filter screen 9, so that the filter screen 9 moves downwards, and in the process that the lower filter screen 9 moves downwards, the two abutting blocks 26 are always abutted against the inner wall of the filter cavity 8 under the elastic action of the third spring 28, so that the sealing performance of the upper space and the lower space of the upper filter screen 9 is ensured;
when the abutting block 26 moves downwards to be in contact with the touch delay switch 29, the second spring 22 is electrified for a period of time, after the second spring 22 is electrified, each coil generates a magnetic field, and the directions of the magnetic fields generated by every two adjacent coils are opposite, so that the second spring 22 contracts to drive the sliding block 21 to move downwards, the sliding block 21 moves downwards to drive the rack 19 to move downwards, the gear 20 drives the first rotating rod 11 to rotate one hundred eighty degrees, the lower filter screen 9 rotates to the upper side, dust is continuously adsorbed, and the upper filter screen 9 rotates to the lower side;
after the power-on time is over, under the elastic action of the second spring 22, the sliding block 21 drives the rack 19 to move upwards, and at the moment, because a one-way bearing is arranged between the gear 20 and the first rotating rod 11, the rotation of the gear 20 cannot drive the first rotating rod 11 to rotate;
meanwhile, after the positions of the two filter screens 9 are interchanged, each abutting block 26 is not in contact with the touch delay switch 29 at the moment, then the operation of the fan 5 can continuously generate the flow of gas, and the gas can impact the impeller 15 when flowing in the gas outlet pipe 6, so that the impeller 15 drives the second rotating rod 16 to rotate;
when the impeller 15 rotates and contacts with the left side of the arc-shaped block 30, the arc-shaped block 30 is pushed to move to the right at this time, so that the fourth spring 32 is compressed, the right space of the extrusion groove 31 is reduced, the air pressure is increased, and the air enters the two arc-shaped air bags 24, so that the two arc-shaped air bags 24 are expanded to drive the two impact balls 23 to move upwards to impact the filter screen 9 positioned below at this time;
through impeller 15's rotation promptly for two continuous striking filter screens 9 of striking ball 23, thereby make filter screen 9 be in the state of shaking, shake off the dust, the next use of the filter screen 9 that is located the below this moment of being convenient for, the dust of shaking off can fall into and collect the intracavity, the follow-up clearance of people of being convenient for.
Compared with the prior art, through the arrangement of the fan 5, when the dust on the screen needs to be cleaned, the fan 5 is only started, so that the air flow in the placing groove 2 → the upper hollow plate 3 → the filter cavity 8 → the fan 5 → the lower hollow plate 3 → the placing groove 2 is generated, the dust on the screen is blown off, and the labor capacity of people is reduced;
when the filter screens 9 positioned above are blocked due to excessive dust adhesion, the positions of the two filter screens 9 are replaced, so that the taken-out dust can be collected continuously after the filter screens 9 are blocked due to excessive dust;
follow-up when collecting the dust, the flow of gas can make two continuous striking clashes of ball 23 filter screen 9 after blockking up to clear up filter screen 9, need not artificial clearance, the subsequent use of being convenient for.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
