[0006] In the above technical solution, preferably, a limiting ring is installed on the inner side of the movable groove, there are multiple groups of the fixed plates, and the air-permeable grooves correspond to the filter plates.

[0007] In the above technical solution, preferably, the internal shape of the filter plate is a star-shaped cross, and the main material of the filter plate is activated carbon.

[0009] In the above technical solution, preferably, the filter cartridge is cross-woven, and the main body of the filter cartridge is made of activated carbon material, and there are multiple groups of mounting rings.

[0014] A method for using a high-efficiency air filter for an automobile is also provided, which is used to operate a high-efficiency air filter structure for an automobile, comprising the following steps:

[0015] S1: First, multiple sets of fixed plates are used to block the air, so that the air passes through the filter plate and flows into the filter cartridge through the air permeable grooves. Finally, the air passes through the filter cartridge again and is discharged. This makes it easier for the air to be filtered once through the filter plate and twice through the filter cartridge, thus allowing the air to be filtered multiple times.

[0016] S2: Secondly, the air blows the inclined control plate, so that the air exerts a lifting force on the control plate, and the control plate drives the connecting plate to move upward, so that the multiple groups of friction blocks move closely against the inner wall of the filter cartridge, and the multiple groups of friction blocks scrape off foreign matter adsorbed on the inner wall of the filter cartridge, clean the inner wall of the filter cartridge, and improve the efficiency of air passing through the filter cartridge;

[0017] S3: Finally, the regulating rod contacts the regulating plate, so that the regulating rod clamps the regulating plate to rotate downward, and the regulating plate drives the rotating shaft to rotate inside the docking ring, so that the limiting block contacts the limiting rod, which is convenient for adjusting the inclination of the regulating plate. The limiting rod and the limiting rod limit the limiting block, so as to limit the inclination of the regulating plate, thereby avoiding a large inclination of the regulating plate, which is not conducive to the air pushing the regulating plate to move.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Block the air through multiple sets of fixed plates, allow the air to pass through the filter plate, and allow the air to flow into the filter cartridge through the air permeable grooves, and finally pass through the filter cartridge again to be discharged, so that the air can be filtered once through the filter plate and twice through the filter cartridge, so that the air can be filtered multiple times and the filtering effect is improved.

[0020] 2. By blowing the inclined control plate with air, the air exerts an upward force on the control plate, and the control plate drives the connecting plate to move upward, so as to facilitate the movement of multiple groups of friction blocks close to the inner wall of the filter cartridge, and to make the multiple groups of friction blocks scrape off foreign matter adsorbed on the inner wall of the filter cartridge, so as to clean the inner wall of the filter cartridge and improve the efficiency of air passing through the filter cartridge.

[0021] 3. When the regulating rod contacts the regulating plate, the regulating rod drives the regulating plate to rotate downward, and the regulating plate drives the rotating shaft to rotate inside the docking ring, so that the limiting block contacts the limiting rod, thereby facilitating the adjustment of the inclination of the regulating plate. The limiting block can be limited by the limiting rod and the limiting rod, thereby limiting the inclination of the regulating plate, thereby preventing the regulating plate from tilting too much, which is not conducive to the air pushing the regulating plate to move.

[0022] 4. The air is filtered once by the filter plate and twice by the filter cartridge, for a total of three times. At the same time, when the air passes through the filter cartridge, the air drives the connecting plate to move, so that multiple groups of friction blocks clean the foreign matter adsorbed on the inner wall of the filter cartridge, which can improve the efficiency of air passing through the filter cartridge and greatly improve the effect of air purification.

[0038] When in use, external air passes through the filter housing 1 and enters the inner side of the filter housing 1, and the air is blocked by the fixed plate 31, so that the air needs to pass through the filter plate 34, so that the filter plate 34 performs the initial purification of the air, so that the filter plate 34 filters out the larger particles contained in the air, and then the air passes through the air permeable groove 33 and flows into the filter cartridge 39, so that the filter cartridge 39 purifies the air again, and the air passes through the filter cartridge 39 again, so that the inner wall of the filter cartridge 39 performs the final purification of the air, thereby achieving multiple purification of the air, by blocking the air through multiple sets of fixed plates 31, allowing the air to pass through the filter plate 34, and allowing the air to flow into the filter cartridge 39 through the air permeable groove 33, and finally the air passes through the filter cartridge 39 again and is discharged, which can achieve the purpose of facilitating the air to be filtered once by the filter plate 34 and twice by the filter cartridge 39, so that the air can be filtered multiple times and the filtering effect is improved.

The limiting rod 413 is in contact with the limiting block 414, and the limiting rod 415 is located below the limiting block 414.

[0040] The air blows onto the surface of the regulating plate 412.

[0043] A method for using a high-efficiency air filter for an automobile is also provided, which is used to operate a high-efficiency air filter structure for an automobile, comprising the following steps:

[0044] S1: First, the air is blocked by multiple sets of fixing plates 31, and the air is passed through the filter plate 34, and the air is passed through the air permeable groove 33 to flow into the filter cartridge 39, and finally the air is discharged through the filter cartridge 39 again, so that the air is filtered once by the filter plate 34 and twice by the filter cartridge 39, so that the air is filtered multiple times;

[0045] S2: Secondly, the air blows the inclined control plate 412, so that the air exerts a lifting force on the control plate 412, and the control plate 412 drives the connecting plate 44 to move upward, so that the multiple groups of friction blocks 45 move closely against the inner wall of the filter cartridge 39, and the multiple groups of friction blocks 45 scrape off foreign matter adsorbed on the inner wall of the filter cartridge 39, clean the inner wall of the filter cartridge 39, and improve the efficiency of air passing through the filter cartridge 39;

[0046] S3: Finally, the regulating rod 47 contacts the regulating plate 412, so that the regulating rod 47 clamps the regulating plate 412 to rotate downward, and the regulating plate 412 drives the rotating shaft 411 to rotate inside the docking ring 410, so that the limiting block 414 contacts the limiting rod 415, so as to facilitate the adjustment of the inclination of the regulating plate 412, and the limiting block 414 is limited by the limiting rod 413 and the limiting rod 415, so as to limit the inclination of the regulating plate 412, so as to avoid the regulating plate 412 from tilting too much, which is not conducive to the air pushing the regulating plate 412 to move.

At the same time, the air blows to the surface of the regulating plate 412. Since the shape of the regulating plate 412 is inclined upward, the air exerts an upward force on the regulating plate 412, so that the regulating plate 412 drives the connecting plate 44 to move upward, and the sliding ring 43 moves upward along the fixed column 42, and the multiple groups of friction blocks 45 generate friction with the inner wall of the filter cartridge 39, so that the multiple groups of friction blocks 45 scrape off foreign matter on the inner wall surface of the filter cartridge 39. When the connecting plate 44 moves upward, the regulating plate 4 When the regulating plate 412 contacts the regulating rod 47, the regulating rod 47 clamps the regulating plate 412 and rotates downward, and the regulating plate 412 drives the rotating shaft 411 to rotate in the inner side of the docking ring 410, so that the limiting block 414 contacts the limiting rod 415, and the limiting rod 415 limits the tilting range of the regulating plate 412. At this time, the regulating plate 412 tilts downward, and at the same time, the air blows the regulating plate 412 to move downward, so that the multiple groups of friction blocks 45 move downward to scrape off the foreign matter adsorbed on the inner wall of the filter cartridge 39. Then, when the regulating plate 412 moves downward, it contacts another group of regulating rods 47, so that the regulating plate 412 changes its tilt again, so that the air can push the regulating plate 412 upward again, so that the multiple groups of friction blocks 45 can move up and down repeatedly to clean and filter. The foreign matter adsorbed on the inner wall of the cylinder 39 is blown by the air to the inclined regulating plate 412, so that the air exerts a lifting force on the regulating plate 412, and the regulating plate 412 drives the connecting plate 44 to move upward, so as to facilitate the multiple groups of friction blocks 45 to move close to the inner wall of the filter cylinder 39, and the multiple groups of friction blocks 45 scrape off the foreign matter adsorbed on the inner wall of the filter cylinder 39, so as to clean the inner wall of the filter cylinder 39, thereby improving the efficiency of air passing through the filter cylinder 39. Secondly, the regulating rod 47 contacts the regulating plate 412, so that the regulating rod 47 clamps the regulating plate 412 to rotate downward, and the regulating plate 412 drives the rotating shaft 411 to rotate inside the docking ring 410, so that the limiting block 414 contacts the limiting rod 415.The purpose of facilitating adjustment of the inclination of the control plate 412 can be achieved, and the limiting block 414 can be limited by the limiting rod 413 and the limiting rod 415, so as to limit the inclination of the control plate 412, so as to avoid the control plate 412 from being tilted too much, which is not conducive to the air pushing the control plate 412 to move. The air is filtered once by the filter plate 34 and twice by the filter cartridge 39, for a total of three times. At the same time, when the air passes through the filter cartridge 39, the air drives the connecting plate 44 to move, so that the multiple groups of friction blocks 45 clean the foreign matter adsorbed on the inner wall of the filter cartridge 39, so as to improve the efficiency of air passing through the filter cartridge 39 and greatly improve the air purification effect.
