DETAILED DESCRIPTION

[0019] See also Figure 1-4 The utility model provides an air guide structure of an air filter, including an air inlet 1, a first air supply pipe 3, a second air supply pipe 2 and a third air supply pipe 4 are equidistantly welded on the side of the air inlet 1, and an air outlet 11 is fixedly arranged at the bottom of the first air supply pipe 3, the second air supply pipe 2 and the third air supply pipe 4, and at the same time, the outer sides of the first air supply pipe 3, the second air supply pipe 2 and the third air supply pipe 4 are fixedly connected to the external frame 9 of the air guide device, and bolts 8 are equidistantly arranged on both sides of the external frame 9 of the air guide device, and a first blade 12 and a second blade 13 are arranged below the air outlet 11, and a blade fixing strip 10 is fixedly connected above the first blade 12 and the second blade 13, and a filter medium filter paper frame 6 is arranged below the external frame 9 of the air guide device, and a filter medium filter paper 5 is fixedly connected to the inside of the filter medium filter paper frame 6, and bolt holes 7 are equidistantly arranged on both sides of the filter medium filter paper frame 6.

[0020] As can be seen from the above, when in use: the air outlet 11 is set to guide the air to flow along a specific path, so that the filter medium filter paper 5 can more fully contact and filter the air; when the air enters the air filter from the air inlet 1, it is dispersed into the first air supply pipe 3, the second air supply pipe 2 and the third air supply pipe 4. Under the guidance of the air outlet 11, the air will pass through the filter medium evenly. The air outlet is designed to be multi-layered, which can make the air form a good circulation inside the filter, prolong the residence time of the air in the filter medium, and thus improve the filtering efficiency of impurities such as dust, pollen, and smoke; the first blade 12 and the second blade 13 can The guide blades can guide the air entering the air filter so that it is evenly distributed on the surface of the filter paper 5 of the filter medium. If there is no first blade 12 and second blade 13, the air may enter from certain areas, resulting in local overuse of the filter element, while other parts are not fully utilized. For example, in the absence of guide, the air flow rate near the center of the air inlet may be faster, while the air flow rate at the edge is slower; the guide blades can adjust the flow direction of the air to allow the air to be distributed on the entire filter element at a more uniform speed and pressure, thereby improving the filtration efficiency and service life of the filter element. The first blade 12 and the second blade 13 are The V-shaped leak-shaped structure allows air to flow along a more reasonable path when passing through the air filter. By optimizing the shape of the intake passage and the air flow path, the number of collisions and turns of air inside the filter is reduced, thereby reducing the resistance caused by sudden changes in the air flow direction. This reduced resistance helps to reduce the pressure difference between the inlet and outlet of the air filter, allowing air to pass through the filter more smoothly. Lower pressure loss means that the engine does not need to overcome too much resistance during the intake process, which greatly improves the engine's intake efficiency. The first blades 12 and the second blades 13 can, to a certain extent, buffer the direct impact of the high-speed airflow entering the air filter on the filter element. Without a diversion measure, the high-speed and strong airflow may damage the surface and internal structure of the filter element. The presence of the first blades 12 and the second blades 13 can prevent impurities such as dust and particulate matter from concentrating in a specific location of the filter element. If impurities accumulate excessively in a certain area, it will increase the local resistance of the filter element, further affecting the intake effect and possibly causing the filter element to clog faster. By evenly distributing air and impurities, the filter element can perform a more balanced filtering operation, avoiding the problem of overall performance degradation caused by localized clogging.

[0021] As a preferred embodiment, the air inlet 1 is a tubular structure made of plastic material, and the first air supply pipe 3, the second air supply pipe 2 and the third air supply pipe 4 are equidistantly installed on the side of the air inlet 1. At the same time, the diameters and lengths of the first air supply pipe 3, the second air supply pipe 2 and the third air supply pipe 4 are consistent, and the bottoms of the first air supply pipe 3, the second air supply pipe 2 and the third air supply pipe 4 are fixedly provided with air outlet holes 11.

[0022] As a preferred embodiment, the outer frame 9 of the guide device is a rectangular structure made of plastic material, and the inner side wall of the outer frame 9 of the guide device is fixedly connected to the blade fixing strip 10, and the first blade 12 and the second blade 13 are fixedly connected below the blade fixing strip 10.

[0023] As a preferred embodiment, the first blade 12 is a sheet structure made of plastic material, and the second blade 13 is fixedly arranged on the left side of the first blade 12. At the same time, the first blade 12 and the second blade 13 are combined into a group of V-shaped leaky structures that are evenly connected to the inner wall surface of the external frame 9 of the guide device.

[0024] As a preferred embodiment, the bolt nails 8 are a threaded structure made of stainless steel, and the bolt nails 8 are divided into two groups of three, each group evenly connected to the bottom of both sides of the external frame 9 of the guide device. At the same time, the height of the bolt nails 8 is 3CM greater than the height of the filter medium filter paper frame 6.

[0025] As can be seen from the above, when in use: installing bolts on both sides of the outer frame 9 of the guide device can ensure that the guide device is firmly connected to the filter medium filter paper frame 6 of the filter. The vibration and bumps of the engine will cause the components inside the air filter to be subjected to shaking and displacement forces. The bolts can withstand these forces to prevent the guide device from loosening or shifting. If the guide device is loose, it may change the direction of the airflow, resulting in uneven air intake and affecting the filtering efficiency of the air filter; workers can precisely install the guide device to the predetermined position by tightening the bolts to ensure that it cooperates well with other components; and, when the air filter needs to be maintained, cleaned or parts (such as filter elements) are replaced, the guide device can be easily removed by unscrewing the bolts, which is more flexible than some complicated fixing methods (such as welding or strong glue), which helps to reduce the difficulty of repair and maintenance.

[0026] As a preferred embodiment, the filter medium filter paper frame 6 is a rectangular hollow structure supported by a plastic material, and the filter medium filter paper 5 is fixedly installed inside the filter medium filter paper frame 6. At the same time, bolt holes 7 are provided on both sides of the filter medium filter paper frame 6, and the bolt holes 7 are divided into two groups of three each and are evenly arranged on both sides of the filter medium filter paper frame 6. At the same time, the position of the bolt hole 7 is consistent with the bolt nail 8, and the bolt nail 8 can pass through the bolt hole 7.

[0027] Working principle: The air outlet 11 is set to guide the air to flow along a specific path, so that the filter medium filter paper 5 can more fully contact and filter the air; when the air enters the air filter from the air inlet 1, it is dispersed in the first air supply pipe 3, the second air supply pipe 2 and the third air supply pipe 4.

If there is no first blade 12 and the second blade 13 , air may enter from certain areas in a concentrated manner, resulting in local overuse of the filter element while other parts are not fully utilized. For example, in the absence of guide air, the air flow rate near the center of the air inlet may be faster, while the air flow rate at the edge is slower; the guide vanes can adjust the flow direction of the air to distribute the air on the entire filter element at a more uniform speed and pressure, thereby improving the filtration efficiency and service life of the filter element. The first blade 12 and the second blade 13 are in a V-shaped leak-shaped structure, so that the air can flow along a more reasonable path when passing through the air filter. By optimizing the shape of the air intake channel and the air flow path, the number of collisions and turns of the air inside the filter is reduced, thereby reducing the resistance caused by the sudden change in the air flow direction. This reduction in resistance helps to reduce the pressure difference between the inlet and outlet of the air filter, allowing air to pass through the filter more smoothly; lower pressure loss means that the engine does not need to overcome too much resistance during the intake process, which greatly improves the engine's intake efficiency.
