Description

Technical Field

[0001] This utility model relates to the field of all-terrain vehicle technology, specifically to an air filter for all-terrain vehicles with easily replaceable filter elements. Background Technology

[0002] All-terrain vehicles, commonly known as "beach buggies" or all-terrain four-wheel off-road vehicles, are simple, practical, and have good off-road performance. They have wide tires that increase the contact area with the ground, generate greater friction, and reduce the pressure of the vehicle on the ground, making them easy to travel on beaches, riverbeds, forest roads, streams, and harsh desert terrain. Therefore, they are popular all over the world.

[0003] The air filter system is a crucial component of all-terrain vehicles. Its mission is to provide the engine with sufficient air while ensuring that the air entering the engine is clean. However, most all-terrain vehicles on the market currently have their air filters installed under the frame, with the air intake located under the chassis. This installation position makes it easy for dust and other substances to be drawn in during vehicle operation. Replacing the air filter element requires removing many parts, leading to inconvenience and low replacement efficiency. Secondly, inexperienced drivers often do not know when a vehicle needs to replace the filter element, resulting in frequent replacements that increase operating costs and waste money. On the other hand, not replacing the filter element for a long time can affect the vehicle's air intake efficiency, leading to insufficient power or even poor filtration, allowing impurities to enter the engine and cause internal damage.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Please refer to Figure 1-6 An air filter for easy-to-replace filter element in all-terrain vehicles includes an air filter body 1, which includes an upper housing 11. A lower housing 12 is fixedly installed at the bottom of the upper housing 11. A rubber sealing ring is provided at the joint between the upper housing 11 and the lower housing 12. An air filter element is detachably connected inside the air filter body 1. External air is drawn into the air filter housing through an intake duct 6. The air passes through the air filter element, and dust, sand and other impurities are effectively blocked on the outer surface and inside of the filter element. The filtered clean air flows out from the outlet through the inner side of the air filter element, enters the carburetor or throttle body through the intake duct 6, and finally mixes with fuel before entering the engine cylinder for combustion.

[0016] The bottom of the air filter body 1 is bolted to a fixed sheet metal part 2, the bottom of which is welded to the vehicle frame 3. A seat 4 is detachably connected to one side of the air filter body 1. The detachable method can be bolt-fixed for long-term use; this is a common installation method and will not be elaborated further. An exhaust duct 5 is connected to the end of the air filter body 1 near the seat 4, and an intake duct 6 is connected to the end away from the seat 4. A filter blockage indicator 7 is threadedly connected to the top of the exhaust duct 5.

[0017] like Figure 3-6 As shown, the filter clogging indicator 7 includes an air filter end interface 71 located at the bottom. The air filter end interface 71 extends into the air outlet duct 5 and is threadedly and sealed to the air outlet duct 5. A sealed chamber 72 is integrally connected to the top of the air filter end interface 71. A top cover 73 is threadedly and sealed to the top of the sealed chamber 72. An atmospheric communication pipe 74 is integrally connected to the top of the top cover 73. A diaphragm 75 is disposed between the top cover 73 and the sealed chamber 72. The diaphragm 75 isolates the atmosphere from the gas inside the air outlet duct 5. A diaphragm 75 is disposed between the diaphragm 75 and the sealed chamber 72. There is a trigger mechanism 76, and a display mechanism 77 is provided on the side walls of the sealed chambers 72 on both sides of the trigger mechanism 76. When the filter element is clogged, airflow becomes difficult. In order to obtain the same amount of air, the engine must generate a larger pressure difference between the air filter's inlet and outlet ends. At this time, the diaphragm 75, which is made of flexible plastic, will move inward toward the outlet duct 5. This drives the trigger mechanism 76 to move, which in turn drives the metal block 774 in the display mechanism 77 to move, so as to remind the user of the air filter element clogging.

[0018] The triggering mechanism 76 includes a trigger rod 761 bonded to the center of the bottom of the diaphragm 75. A trigger strip 762 is integrally connected to the bottom of the trigger rod 761. The bottom of the trigger strip 762 abuts against the bottom wall of the sealed chamber 72. Magnets 763 are bonded to both sides of the trigger strip 762. When the diaphragm 75 descends, it causes the trigger rod 761 to descend. The trigger strip 762 and the trigger rod 761 are made of the same material, and thus will be subjected to pressure and extend to both sides, such that the magnets 763 approach the display mechanism 77.

[0019] The display mechanism 77 includes a transparent tube 771. One end of the transparent tube 771 is connected to a sealed chamber 72 and is threadedly sealed to the side wall of the sealed chamber 72. The other end is threadedly sealed to an end cap 772. A spring 773 is provided on the side of the end cap 772 near the magnet 763. A metal block 774 is fixedly connected to one side of the spring 773. The metal block 774 is slidably connected to the transparent tube 771. An indicator line is provided on the outside of the transparent tube 771. A stop bar is provided on the end of the transparent tube 771 near the sealed chamber 72. When the magnet 763 approaches the transparent tube 771, the magnetic force on the metal block 774 increases, allowing the metal block 774 to overcome the elastic force of the spring 773 and move closer to the magnet 763. The position of the metal block 774 will move from the side of the indicator line near the end cap 772 to the side of the indicator line near the sealed chamber 72. The user can judge the clogging status of the filter element by the position of the metal block 774 relative to the indicator line, and then decide whether to replace the air filter element.

[0020] Furthermore, the trigger bar 762 includes a straight portion 7621, an inclined portion 7622, ​​a curved portion 7623, and a vertical portion 7624. The straight portion 7621 is fixedly connected to the trigger rod 761. The inclined portion 7622 is disposed on both sides of the straight portion 7621. The curved portion 7623 is disposed on both sides of the straight portion 7621, and the bottom of the curved portion 7623 abuts against the bottom wall of the sealed chamber 72. The vertical portion 7624 is fixedly connected to the curved portion 7623. The curved portion 7623 abuts against the bottom wall of the sealed chamber 72 and then slides to both sides, so that the magnet 763 approaches the metal block 774.

[0021] Working principle: When the air filter element becomes clogged, a pressure difference is generated between the atmosphere and the two sides of the outlet duct 5, causing the diaphragm 75 to move downward towards the outlet duct 5. This causes the trigger rod 761 to press down the trigger bar 762. The curved part 7623 of the trigger bar 762 slides along the sealed chamber 72 to both sides. The magnet 763 is attracted to the metal block 774 and moves towards the sealed chamber 72. The metal block 774 moves to the side of the indicator bar near the sealed chamber 72, thus creating a pressure difference between the air filter inlet and outlet. This indicates that the air filter element is severely clogged and needs to be replaced. After removing the seat, the air filter element can be replaced.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
