Technical Field

[0001] This utility model relates to the field of automotive air filter technology, and in particular to an automotive air filter with snow-proof air intake. Background Technology

[0002] Automotive air filters can effectively filter out dust, sand and other impurities suspended in the air, preventing them from entering the engine cylinders, reducing wear on parts such as valves, cylinders and pistons, avoiding serious malfunctions such as "cylinder scoring" and "cylinder explosion", and extending the engine's service life.

[0003] In the current technology, most automotive air filters are usually installed on the lower side of the front of the car. Due to their low position, they are not convenient to remove and replace. Repairmen or car owners need to spend more time and effort when replacing air filters, which increases the labor costs of repair shops.

[0004] In response to the technical problem of the inconvenience of disassembling and replacing vehicle air filters, this application proposes a vehicle air filter with snow-proof air intake. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where it is inconvenient to disassemble automotive air filters. The proposed automotive air filter with snow-proof air intake allows for easy removal of the filter body from the fixed frame simply by rotating the rotating ring and pushing the sliding rod upwards. This simple operation allows maintenance personnel to quickly disassemble the air filter without spending excessive time on complex disassembly procedures, thereby improving maintenance efficiency, shortening the overall vehicle maintenance time, and reducing labor costs for repair shops.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vehicle air filter with snow-proof air intake includes an air filter body. Multiple mounting frames are fixedly connected to both the front and rear ends of the air filter body. The inner walls of the mounting frames are connected to fixing frames via snap-fit ​​components for the assembly and disassembly of the air filter body. A blocking component is provided on the inner wall of the air filter body to block most of the snowflakes. Through holes are provided at all four ends of the fixing frames.

[0008] Furthermore, the buckle assembly includes a slot formed in the inner wall of the mounting frame, and each slot has a block on its inner wall. The shape of the block matches the slot, and the outer wall of the block is slidably connected to the inner wall of the fixed frame.

[0009] Furthermore, each of the inner walls of the fixed frame is slidably connected to a sliding rod, and each of the inner walls of the sliding rod is rotatably connected to a plurality of connecting rods, the other end of each connecting rod being rotatably connected to the inner wall of the locking block.

[0010] Furthermore, each of the slide bars has a rotating ring on its outer wall, and each rotating ring has a limit ring fixedly connected to its bottom end.

[0011] Furthermore, the inner wall of each slide rod is provided with a limiting groove, and the outer wall of each limiting ring is provided on the inner wall of the limiting groove, and the shape of the limiting ring matches the limiting groove.

[0012] Furthermore, each of the rotating rings has a threaded sleeve fixedly connected to its top end, and each of the inner walls of the fixed frame has a threaded groove on its lower side. The outer wall of each threaded sleeve is threadedly connected to the inner wall of the threaded groove.

[0013] Furthermore, the inner wall of the fixed frame is provided with multiple sliding grooves, and the shape of the mounting frame matches the sliding grooves.

[0014] Furthermore, the blocking assembly includes a first baffle plate fixedly connected to the inner wall of the air filter body, and a second baffle plate fixedly connected to the bottom end of the air filter body.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, when it is necessary to disassemble the air filter body, simply rotate the rotating ring and push the slide rod upward to remove the air filter body from the fixed frame. The operation is simple, and maintenance personnel can quickly complete the disassembly of the air filter without spending a lot of time on a complicated disassembly process, thereby improving maintenance efficiency, shortening the overall vehicle maintenance time, and reducing the labor costs of the repair shop.

[0017] In this invention, by providing a first baffle and a second baffle, solid snowflakes are effectively blocked, ensuring that the air entering the air filter body remains unobstructed. This ensures that the engine has enough fresh air for combustion, maintains normal operation, and avoids problems such as reduced engine power, vibration, or even stalling due to insufficient air intake.

[0024] 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.

[0025] Reference Figures 1-3 As shown, one embodiment of this utility model provides a vehicle air filter with snow-proof air intake, including an air filter body 1. Multiple mounting frames 4 are fixedly connected to both the front and rear ends of the air filter body 1. A fixing frame 6 is provided on the inner wall of each mounting frame 4. A slot 5 is provided on the inner wall of each mounting frame 4. A locking block 10 is provided on the inner wall of each slot 5. The shape of the locking block 10 fits the slot 5. The outer wall of each locking block 10 is slidably connected to the inner wall of the fixing frame 6. A sliding rod 8 is slidably connected to the inner wall of each fixing frame 6. Multiple connecting rods 9 are rotatably connected to the inner wall of each sliding rod 8. The other end of each connecting rod 9 is rotatably connected to a locking block. The inner wall of the slide rod 8 and the outer wall of the slide rod 8 are both provided with rotating rings 12. The bottom end of the rotating rings 12 is fixedly connected to the limiting rings 13. The inner wall of the slide rod 8 is provided with limiting grooves 11. The outer wall of the limiting rings 13 is provided on the inner wall of the limiting grooves 11. The shape of the limiting rings 13 fits the limiting grooves 11. The top of the rotating rings 12 is fixedly connected to the threaded sleeves 14. The lower side of the inner wall of the fixing frame 6 is provided with threaded grooves. The outer wall of the threaded sleeves 14 is threadedly connected to the inner wall of the threaded grooves. The inner wall of the fixing frame 6 is provided with multiple sliding grooves 7. The shape of the mounting frame 4 fits the sliding grooves 7 for the disassembly and assembly of the air filter body 1.

[0026] Specifically, the fixing frame 6 is installed inside the vehicle body by bolts passing through the through holes. When it is necessary to disassemble the air filter body 1, simply rotate the rotating ring 12 and push the slide bar 8 upward to remove the air filter body 1 from the fixing frame 6. The operation is simple, and maintenance personnel can quickly complete the disassembly of the air filter without spending a lot of time on complicated disassembly procedures, thereby improving maintenance efficiency, shortening the overall vehicle maintenance time, and reducing the labor costs of the repair shop.

[0027] Reference Figure 1 , Figure 2 and Figure 4 As shown, the fixed frame 6 has through holes at all four ends, the air filter body 1 has a first baffle 2 fixedly connected to the inner wall, and the air filter body 1 has a second baffle 3 fixedly connected to the bottom end, so as to block most of the snowflakes.

[0028] Specifically, by setting the first baffle 2 and the second baffle 3, the solid snowflakes are effectively blocked, so that the air entering the air filter body 1 remains unobstructed, ensuring that the engine has enough fresh air for combustion, maintaining normal operation, and avoiding problems such as reduced engine power, vibration or even stalling due to insufficient air intake.

[0029] Working principle: First, during use, air enters the second baffle 3 from the lower left side of the air filter body 1, blocking the snowflakes for the first time. Simultaneously, the air passes through the second baffle 3 to the first baffle 2, blocking most of the snowflakes. The air then enters the air filter body 1 and the vehicle body to the right. When disassembling the air filter body 1, the rotating ring 12 is rotated, causing the threaded sleeve 14 to rotate. This causes the threaded sleeve 14 to rotate within the threaded groove, moving it upwards and pushing the limiting ring 13 out of the limiting groove 1. Remove the slide bar 8 from the slot 5 and push it upwards. The slide bar 8 will rotate the connecting rods 9 on both sides and cause the locking blocks 10 on both sides to slide inwards. Remove the locking blocks 10 from the slots 5, and then remove the air filter body 1 downwards to complete the disassembly. When installing, first align the four mounting frames 4 with the slide grooves 7 and push them upwards. After installation, pull the slide bar 8 downwards to lock the locking blocks 10 into the slots 5 respectively. Then rotate the rotating ring 12 in the opposite direction to lock the limiting ring 13 into the limiting groove 11 to limit the slide bar 8, thus completing the installation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
