[0002] The working principle of a car air filter is mainly to filter impurities in the air through the filter element. Its working principle is as follows: Inertial separation: When air passes through the filter, larger impurity particles will be thrown to the edge of the filter due to inertia, thereby separating from the air; the filter element in the air filter is usually made of paper, cotton or fiber materials, which can block tiny particles in the air, such as dust, pollen, bacteria, etc., thereby achieving air filtration; the working principle of a car air filter is a complex process, involving multiple principles such as inertial separation, filtration and adsorption. Through the synergistic effect of these principles, the air filter can effectively filter impurities in the air, provide clean air for the engine, and ensure the normal operation of the engine;
[0003] When the filter media in the air filter filters dust-laden gas, the jagged filter media tends to stick together, resulting in an inability to evenly filter the dust-laden gas. Uneven filtration will cause some larger particles of impurities to enter the engine; these impurities will scrape against the piston, cylinder wall and other components during movement inside the engine, causing increased engine wear and shortening the engine's service life.

[0019] See also Figure 1-4 The utility model provides an air filter with a spiral structure, comprising an outer filter frame 1, an air filter material 2 is fixedly installed inside the outer filter frame 1, and a deflector 5 is fixedly installed on the surface of the outer filter frame 1, and an air inlet frame 6 is fixedly installed on the surface of the deflector 5, and an air filter slot 21 is provided on the surface of the air filter material 2, four groups of through holes are evenly opened on the surface of the deflector 5, and four groups of screw holes are evenly opened on the surface of the outer filter frame 1, and fixing bolts pass through the through holes opened on the deflector 5 and are screwed and fixed to the inside of the screw holes opened on the surface of the outer filter frame 1.
[0020] As can be seen from the above, during use, when airflow impacts the surface of the air deflector 5, multiple groups of air inlet frames 6 are evenly arranged on the surface of the air deflector 5, and multiple groups of air filter slots 21 are evenly arranged on the surface of the air filter material 2. The multiple groups of air inlet frames 6 are evenly arranged on the surface of the air deflector 5, and the number of air inlet frames 6 and air filter slots 21 is the same. The air inlet frames 6 and air filter slots 21 are arranged relative to each other, so that the dust-laden airflow enters the interior of the filter outer frame 1 through the multiple groups of air inlet frames 6 respectively, so that the dust-laden air can enter the interior of the air filter slots 21 in a grouped manner. This can achieve uniform filtering of the dust-laden air by the air filter material 2. The uniform filtration can effectively remove impurities of various sizes in the air and prevent them from entering the engine. After the clean air enters the engine, it can reduce the wear of key components such as the piston and cylinder, thereby extending the service life of the engine. The evenly filtered air mixes more fully with the fuel, making the combustion process more stable and efficient. This not only improves the power output of the engine, but also reduces fuel consumption and exhaust emissions.
[0021] A plurality of air filter slots 21 are evenly arranged on the surface of the air filter material 2 , and a plurality of air inlet frames 6 are evenly arranged on the surface of the air guide cover 5 , and the number of the air inlet frames 6 is the same as the number of the air filter slots 21 .
[0022] As a preferred embodiment, the air inlet frame 6 is arranged opposite to the air filter slot 21 , and the length of the air inlet frame 6 is equal to the length of the air filter slot 21 , and the surface of the air inlet frame 6 is arranged above the surface of the air deflector 5 .
[0023] As can be seen from the above, when in use, the surface of the serrated air filter material 2 is respectively equipped with the first spiral support bar 3 and the second spiral support bar 31. The setting of the first spiral support bar 3 and the second spiral support bar 31 can expand the air filter slot 21 in the serrated air filter material 2 to prevent the air filter slot 21 from shrinking after being squeezed, making it unable to filter the dust-laden gas, or reducing its filtering area for the dust-laden gas. The setting of the first spiral support bar 3 and the second spiral support bar 31 can ensure the reliability and stability of the air filter slot 21 when filtering the gas. When installing the filter outer frame 1 and the air guide cover 5, the positioning block 51 and the positioning groove 4 can be used for quick positioning and installation. The filter outer frame 1 and the air guide cover 5 are a detachable structure to ensure that the air guide cover 5 can continue to be used without being damaged.
[0024] Positioning blocks 51 are fixedly installed on both sides of the bottom of the air deflector 5, and two groups of positioning grooves 4 are evenly opened on the inner wall surface of the filter outer frame 1. At the same time, the positioning grooves 4 are adapted to the sizes of the positioning blocks 51, and the positioning blocks 51 are inserted into the inside of the positioning grooves 4.
[0025] As a preferred embodiment, the filter outer frame 1 and the air deflector 5 are positioned and installed via the positioning groove 4 and the positioning block 51 , and the depth of the positioning groove 4 is equal to the height of the positioning block 51 .
[0026] The air filter material 2 is arranged in a zigzag shape, and the first spiral support bar 3 and the second spiral support bar 31 are respectively installed on both sides of the surface of the air filter material 2, and the first spiral support bar 3 and the second spiral support bar 31 are symmetrical structures about the central axis of the filter outer frame 1. At the same time, the ends of the first spiral support bar 3 and the second spiral support bar 31 are screwed and fixed on the inner wall of the filter outer frame 1, and the first spiral support bar 3 and the second spiral support bar 31 are both clamped on the crest of the air filter material 2.
[0027] Working principle: During use, when the airflow impacts the surface of the air deflector 5, multiple groups of air inlet frames 6 are evenly arranged on the surface of the air deflector 5, and multiple groups of air filter slots 21 are evenly opened on the surface of the air filter material 2. Multiple groups of air inlet frames 6 are evenly arranged on the surface of the air deflector 5, and the number of air inlet frames 6 and air filter slots 21 are consistent. The air inlet frames 6 and the air filter slots 21 are arranged relative to each other, so that the dust-laden airflow passes through the multiple groups of air inlet frames 6 and enters the interior of the filter outer frame 1 respectively, so that the dust-laden gas can enter the interior of the air filter slots 21 in groups in sequence, and the air filter material 2 can perform uniform filtering on the dust-laden gas. Uniform filtration can effectively remove impurity particles of various sizes in the air and prevent them from entering the engine. After the clean air enters the engine, the wear of key components such as the piston and cylinder can be reduced, and the service life of the engine can be extended; the evenly filtered air is more fully mixed with the fuel, making the combustion process more stable and efficient. This not only improves the power output of the engine, but also reduces fuel consumption and exhaust emissions. At the same time, the surface of the serrated air filter material 2 is respectively equipped with a first spiral support bar 3 and a second spiral support bar 31. The setting of the first spiral support bar 3 and the second spiral support bar 31 can expand the air filter slot 21 in the serrated air filter material 2 to prevent the air filter slot 21 from shrinking after being squeezed, making it unable to filter dust-laden gas, or reducing its filtering area for dust-laden gas. The setting of the first spiral support bar 3 and the second spiral support bar 31 can ensure the reliability and stability of the air filter slot 21 when filtering the gas. When the filter outer frame 1 and the air deflector 5 are being installed, they can be quickly positioned and installed through the positioning block 51 and the positioning groove 4. The filter outer frame 1 and the air deflector 5 are a detachable structure to ensure that the air deflector 5 can continue to be used without being damaged.
