Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a high-efficiency automobile air filter. Background Art

[0002] The car air filter is an item that removes particulate impurities from the air inside the car. The car air conditioning filter can effectively reduce the pollutants that enter the car through the heating, ventilation and air conditioning system, and prevent the inhalation of pollutants that are harmful to the body. The car air filter is mainly responsible for removing particulate impurities in the air. When piston machinery (internal combustion engines, reciprocating compressors, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of parts, so an air filter must be installed.

[0003] During the driving of the car, severe shaking will occur, which will cause the internal components to vibrate. Since the car air filter generally adopts a snap-on connection, the snap-on connection will cause some parts to loosen during the vibration process, and gaps will appear between the connectors. If a gap appears at the connection between the air filter and the engine, air with a heavy dust content will be directly delivered to the engine, affecting the service life of the engine. At the same time, the direct snap-on connection between the filter structure and the engine will affect the stability of the device. During the operation of the filter, sharp large stones and gravel will hit the filter paper at a high speed, affecting the service life of the filter paper for a long time. For this reason, we propose an efficient car air filter to facilitate the protection of the filter element in the air filter. Utility Model Content

[0004] Aiming at the problems in the prior art, the utility model provides a high-efficiency automobile air filter.

[0005] The technical solution adopted by the utility model to solve its technical problems is a high-efficiency automobile air filter, comprising an air filter housing and an intake pipe, a filter mechanism installed at the shell wall of the air filter housing, and the filter mechanism is composed of a limit frame, an air filter core, an extrusion frame, a sealing cover and a locking bolt combination, the limit frame is fixedly installed at the inner wall of the air filter housing, an air filter core is placed on the inner wall of the air filter housing, the air filter core is located at the top of the limit frame, the shell top of the air filter housing is connected with a sealing cover by a locking bolt, the bottom of the sealing cover is fixedly installed with an extrusion frame, and the extrusion frame is located at the top of the air filter core.

[0006] By adopting the above technical solution, when installing the air filter element, since the filter mechanism is installed on the wall of the air filter housing, and the filter mechanism is composed of a limit frame, an air filter element, an extrusion frame, a sealing cover, and a locking bolt, after the operator places the air filter element in the limit frame inside the air filter housing, the extrusion frame is fixedly installed at the bottom of the sealing cover. After the locking bolt penetrates the sealing gasket and connects the sealing cover to the air filter housing, the extrusion frame is positioned on top of the air filter element. The extrusion frame and the limit frame squeeze and fix the air filter element, so that the vibration of the vehicle causes a gap between the air filter element and the air filter housing, allowing dust to enter the engine.

[0007] Specifically, it also includes a debris removal mechanism, and the debris removal mechanism is installed at the pipe opening of the air inlet pipe.

[0008] By adopting the above technical solution, the air filter can be pre-filtered by the impurity removal mechanism.

[0009] Specifically, the impurity removal mechanism is composed of a cylinder, honeycomb holes, an external threaded tube, a threaded groove and a gasket. A threaded groove is provided on the inner wall of the air intake pipe, and an external threaded tube is threadedly connected to the groove wall of the threaded groove. The other end of the external threaded tube is connected and welded to the cylinder, and a honeycomb hole is provided on the cylinder wall. The external threaded tube passes through the gasket.

[0010] By adopting the above technical solution, when the air filter is pre-filtered, since a debris removal mechanism is installed at the pipe mouth of the intake pipe, the debris removal mechanism is composed of a cylinder, a honeycomb hole, an external threaded tube, a threaded groove and a gasket. Since a threaded groove is provided on the inner wall of the intake pipe, after the external threaded tube is passed through the gasket, the external threaded tube is threadedly connected to the threaded groove, thereby fixing the cylinder. Since honeycomb holes are provided on the wall of the cylinder, when air enters the intake pipe, sharp stones in the air are blocked by the honeycomb holes, thereby protecting the air filter element in the air filter housing.

[0011] Specifically, an air inlet pipe is connected and installed at the top of the sealing cover.

[0012] By adopting the above technical solution, air can be taken into the air filter housing through the air intake pipe.

[0013] Specifically, a sealing gasket is connected between the shell wall of the air filter shell and the sealing cover, and the locking bolt passes through the sealing gasket.

[0014] By adopting the above technical solution, the air filter housing and the sealing cover can be sealed by the sealing gasket.

[0015] Beneficial effects of the utility model:

After the sealing cover is connected to the air filter housing through the locking bolt through the sealing gasket, the extrusion frame is located on the top of the air filter element. The air filter element is squeezed and fixed by the extrusion frame and the limit frame. As a result, the vibration of the vehicle causes a gap between the air filter element and the air filter housing, causing dust to enter the engine.
