As an embodiment of the present invention, the upper surface of the connecting block 76 is uneven, and the lower end of the connecting block 76 is provided with a plurality of through holes 12; two sides of the lower surface of the connecting block 76 are fixedly connected with an elastic rope 13; the other end of the elastic rope 13 is connected with an elastic ball 14; the elastic balls 14 are contacted with two sides of the lower end of the dust box 78; when the filter element cleaning device works, the upper surface of the connecting block 76 is arranged to be uneven, so that the contact area between the connecting block 76 and the filter element 6 is increased, and the cleaning effect of the connecting block 76 on the filter element 6 is better; the through hole 12 is formed at the lower end of the connecting block 76, so that when gas enters from the main gas inlet 3, the shielding of the connecting block 76 on the gas is reduced; when the connecting block 76 moves, the elastic rope 13 is driven to drive the elastic ball 14 to move, so that the elastic ball 14 knocks two sides of the lower end of the dust box 78, and therefore impurities on two sides of the lower end of the dust box 78 enter the bottom end, and dust and impurities are better collected; the working effect of the air filter is further enhanced.
When the automobile air filter works, the air filter needs to work all the time when an automobile engine works, but a user often forgets to clean the filter element 6 of the air filter in time, so that the dust accumulated on the air filter is too much to influence the normal work of the air filter, and the service life of the engine is influenced; therefore, the invention arranges a cleaning module 7 at the lower end of the filter element 6; when a user starts the automobile and then preheats the automobile, the controller controls the driving motor 71 to work, so that the driving motor 71 drives the first sliding block 74 to move along the direction of the filter element 6 by driving the screw rod 72, and the first sliding block 74 drives the second sliding block 75 to move by driving the connecting block 76; when the first sliding block 74 moves to the other end of the filter element 6, the driving motor 71 is driven reversely, the first sliding block 74 is driven to drive the connecting block 76 and the second sliding block 75 to move reversely, and the screw rod 72, the polish rod 73, the first sliding block 74 and the second sliding block 75 form a screw rod sliding block pair repeatedly; in the process that the connecting block 76 moves back and forth, the connecting block 76 is in contact with and collides with the filter element 6, the filter element 6 cannot be greatly damaged because the connecting block 76 is made of an elastic material, and impurities adhered to the filter element 6 fall into the dust box 78 through the connecting block 76; when the automobile starts to run, the controller controls the driving motor 71 to stop working, so that the working process of an engine in the running process of the automobile is not influenced in the cleaning process; when the automobile is started next time, the cleaning module 7 works again to ensure the state of the air filter before working; when the dust in the dust box 78 is about to fill the dust box 78, the dust box 78 is manually pulled out along the first sliding groove 77 through the lifting ring 79, and the dust box 78 is put into the lower shell 2 again after the dust is disposed; the use effect of the air filter is improved; when the dust box 78 is cleaned or the filter element 6 is replaced, dust is easy to fly into the main air outlet 4, and the working performance of the engine is affected; the shielding module 8 is arranged beside the main air outlet 4; when the dust box 78 is pulled out, the magnet 86 at the end of the dust box 78 drives the magnet 85 at one end of the elastic rod 83 to drive the elastic rod 83 to slide along the sliding groove 82 through magnetic attraction; when the elastic rod 83 moves to stretch the first elastic belt 81, the first elastic belt 81 shields the main air outlet 4; when the dust box 78 drives the elastic rod 83 to slide to the tail end of the second sliding groove 82, the second sliding groove 82 prevents the elastic rod 83 from continuously sliding, so that the third magnet 86 is separated from the second magnet 85, and the second magnet 85 is magnetically attracted with the first magnet 84 at the tail end of the second sliding groove 82 again; the dust box 78 is drawn out for cleaning, then the upper cover 1 is opened, the old filter element 6 is taken out and replaced by a new filter element 6, at the moment, dust on the filter element 6 cannot enter the main air outlet 4, the upper cover 1 is buckled, and the dust box 78 extends into the lower shell 2; when the dust box 78 slides to the second sliding groove 82, the dust box 78 continues to slide forwards, so that the first magnet 84 is separated from the second magnet 85, the third magnet 86 is magnetically attracted again with the second magnet 85, the dust box 78 continues to drive the elastic rod 83 to reversely slide along the second sliding groove 82, the first elastic belt 81 contracts to expose the main air outlet 4, and the air filter resumes normal operation; the service life of the air filter is prolonged; meanwhile, the filter element 6 needs to be clamped when being placed into the lower shell 2, so that when the air filter works, air does not easily generate noise when entering the lower shell 2, but the filter element 6 needs to be clamped loosely to be taken out conveniently when being replaced; the invention arranges a compacting module 9 in the lower shell 2; after the filter element 6 is placed in the lower shell 2, the air bag 91 is manually pressed, so that the air in the air bag 91 enters the vent pipeline 95 through the one-way air outlet 93, meanwhile, the outside atmosphere enters the air bag 91 through the one-way air inlet 92, and the process is repeated; when the air in the vent pipe 95 is full, the second elastic band 96 is expanded and is further tightly squeezed with the sealing ring 5, and the filter element 6 is more stable in the lower shell 2; when the filter element 6 needs to be replaced, the two one-way air outlets 93 are pulled out from the air duct 95, so that air in the air duct 95 is discharged, the second elastic belt 96 retracts, a gap is formed between the second elastic belt and the sealing ring 5 again, and the filter element 6 is convenient to take out; the simplicity of the air filter in the using process is improved; therefore, the sponge foam plate 10 is arranged in the middle layer, so that the noise generated by the air filter during working is absorbed; meanwhile, the sponge foam boards 10 are obliquely arranged in a crossed manner, so that the use amount of the sponge foam boards 10 can be reduced, noise is reflected for many times, and the absorption effect is better; the using effect of the air filter is further improved; furthermore, the dust box 78 is arranged to be in an arc-shaped concave shape, so that the connecting block 76 enables dust and impurities on the filter element 6 to smoothly fall to the lowest end of the dust box 78 through the filter element 6; when large-particle impurities fall to the bottom end, the impurities are adhered to the adhesive tape 11, so that the situation that the impurities are blown away by gas is avoided when the air filter works inside; the working effect of the air filter is enhanced; in addition, the upper surface of the connecting block 76 is arranged to be uneven, so that the contact area between the connecting block 76 and the filter element 6 is increased, and the cleaning effect of the connecting block 76 on the filter element 6 is better; the through hole 12 is formed at the lower end of the connecting block 76, so that when gas enters from the main gas inlet 3, the shielding of the connecting block 76 on the gas is reduced; when the connecting block 76 moves, the elastic rope 13 is driven to drive the elastic ball 14 to move, so that the elastic ball 14 knocks two sides of the lower end of the dust box 78, and therefore impurities on two sides of the lower end of the dust box 78 enter the bottom end, and dust and impurities are better collected; the working effect of the air filter is further enhanced.
