Description
Technical Field
[0001] The utility model relates to the technical field of automotive parts, and more specifically, to an air filter that is convenient for firm installation. Background Technique
[0002] The basic function of an air filter is to provide clean air for the engine, prevent impurities such as dust and sand particles from entering the cylinder, thereby reducing the wear of the engine and extending its service life. Different types of air filters have different working principles, including inertial type, filtration type, and oil bath type, etc. The inertial air filter uses centrifugal inertial force to separate impurities; the filtration air filter blocks impurities through filter paper or non-woven fabric; the oil bath air filter uses engine oil to adsorb impurities. These designs enable the air filter to effectively protect the engine and avoid wear and failures caused by inhaling impurities.
[0003] In the automotive field, the air filter is crucial for maintaining the normal operation of the vehicle engine. If air enters the cylinder directly without filtration, the dust suspended in the air will be inhaled, accelerating the wear of the piston group and the cylinder, and even causing serious "cylinder scoring" phenomena. Therefore, regular inspection and maintenance of the air filter are the keys to ensuring vehicle performance and extending its service life. In addition, the automotive air conditioner filter also has the functions of filtering smoke odor, pollen, dust, harmful gases, and peculiar smells in the air, further improving the air quality inside the vehicle.
[0004] Air filters are widely used and generally filter and block dust. For example, the traditional installation of air filters used in automobiles is of the plug-in type, and the insertion part is sealed by the housing. Due to the differences in different automotive categories and application locations, the installation methods are also different. For example, the positions of air filters used inside the vehicle are relatively tricky, and it is difficult to disassemble the housing, resulting in the need for users to use tools to dig out the air filter every time they replace it. The operation is relatively difficult and it is easy to damage related accessories.
[0005] Therefore, improvements are made to address the above problems. Content of the Utility Model

Specific Embodiments
[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] As Figures 1 to 4 shown, this embodiment proposes an air filter that is convenient for firm installation, including
[0030] filter body 1 and top groove 2, and top groove 2 is opened at the top of filter body 1;
[0031] plug-in fixing component 3, and plug-in fixing component 3 is arranged in top groove 2;
[0032] pop-up component 4, and pop-up component 4 is arranged at the bottom of filter body 1;
[0033] The inserted and fixed component 3 includes a rotating block 3-1 which is rotatably connected in the top groove 2. Connecting grooves 3-2 are formed on both sides of the rotating block 3-1. A pull rod 3-3 is rotatably connected in the connecting groove 3-2 by a pin shaft. One end of the pull rod 3-3 is rotatably connected with a movable block 3-4 by a pin shaft. A groove 3-5 is formed on the end face of the movable block 3-4. A tension spring 3-6 is connected between the groove 3-5 and the inner wall of the top groove 2. A pair of round holes 3-7 are formed on the inner end face of the top groove 2. A pair of insertion rods 3-8 are arranged on the side end face of the movable block 3-4. The insertion rods 3-8 are movably sleeved and connected in the round holes 3-7. A convex layer 3-9 is arranged on the upper end face of the rotating block 3-1.
[0034] In this embodiment, in order to achieve the effect of fixing and supporting the filter body 1 after insertion, the inserted and fixed component 3 is designed. A rotating block 3-1 is rotatably connected in the top groove 2. Connecting grooves 3-2 are formed on both sides of the rotating block 3-1, and a pull rod 3-3 is rotatably connected inside. One end of the pull rod 3-3 is rotatably connected with a movable block 3-4 by a pin shaft. A groove 3-5 is formed inside the movable block 3-4. A tension spring 3-6 is connected between the groove 3-5 and the inner wall of the top groove 2. When the rotating block 3-1 rotates, it will pull the movable block 3-4 through the pull rod 3-3, causing the movable block 3-4 to move outwards and being able to reset by the elastic force of the tension spring 3-6. Two round holes 3-7 are formed on both sides inside the top groove 2. Insertion rods 3-8 are arranged on the end face of the movable block 3-4 and are movably sleeved in the round holes 3-7. When the filter body 1 is placed, the insertion rods 3-8 can be retracted into the top groove 2. After insertion and releasing the rotating block 3-1, the insertion rods 3-8 move outwards by the elastic force of the tension spring 3-6 to achieve the insertion effect.
[0035] Furthermore, the ejection component 4 includes a bottom groove 4-1 which is formed at the bottom of the filter body 1. A plurality of springs 4-2 are arranged in the bottom groove 4-1. The lower ends of the springs 4-2 are connected with a support layer 4-3.
[0036] In this embodiment, in order to achieve the effect of ejecting the filter body 1 when taking it out, the ejection component 4 is designed. A bottom groove 4-1 is formed at the bottom of the filter body 1. A plurality of springs 4-2 are arranged in the bottom groove 4-1. The lower ends of the springs 4-2 are connected with a support layer 4 - 3. When the support layer 4-3 is squeezed, it can be contracted into the bottom groove 4-1. When taking out the filter body 1, the filter body 1 can be jacked upwards by the elastic force of the springs 4-2.
[0037] Furthermore, convex strips 5 are arranged on both sides of the filter body 1.
[0038] In this embodiment, by providing two convex strips 5, it is convenient to correct the insertion position of the filter component and ensure that no deviation occurs.
[0039] Furthermore, the thickness of the support layer 4-3 is the same as the depth inside the bottom groove 4-1.
[0040] In this embodiment, since the thickness is the same as the depth, it is convenient for the support layer 4-3 to be on the same plane as the outer surface of the filtration component, avoiding jamming during installation.
[0041] Furthermore, both ends of the bottom groove 4-1 extend upward to both sides of the filtration body 1, and the support layer 4-3 is in a U-shaped structure.
[0042] In this embodiment, due to the U-shaped structure, the support layer 4-3 can fit closely inside the bottom groove 4-1 and will not be restricted when popping out.
[0043] Furthermore, the side surface of the convex layer 3-9 is a polygon structure around one week.
[0044] In this embodiment, due to the polygon structure, it is convenient for fingers to pinch, achieving an anti-slip effect.
[0045] When installation is required, turn the rotating block by the convex layer 3-9. When rotating, pull the movable block 3-4 through the pull rod 3-3, retract the round rod into the top groove 2, insert the filtration component into the vehicle and press it downward. After pressing to the bottom, release the rotating block, and pull the movable block 3-4 through the pulling force of the tension spring 3-6, then insert the insertion rod 3-8 into the groove in the vehicle. When removing, similarly turn the rotating block 3-1, pull out the insertion rod 3-8. After pulling out, the filtration body 1 will be pushed upward by the elastic force of the bottom spring 4-2. After popping out a certain position, it can be pinched and pulled out the filtration body 1 outward.
[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
