Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, in particular to an air filter for a motorcycle. Background Art

[0002] Every motorcycle is equipped with an air filter, which filters outside air before entering the engine's combustion chamber. Currently, some air filters are equipped with an intake pipe, through which air is drawn in. The intake end of the intake pipe is extended a certain distance and fixed to a location on the frame where rain and dust cannot reach it. This setup requires a separate fixing to secure the intake pipe, which is costly. Furthermore, the long extension of the intake pipe makes it difficult to ensure smooth air flow into the air filter.

[0003] In summary, the problem of how to design a motorcycle air filter with a simpler structure and more stable air intake remains to be solved. Utility Model Content

[0004] The purpose of the utility model is to provide a motorcycle air filter, and the technical problem to be solved is how to make the motorcycle air filter structure more concise and the air intake more stable.

[0005] To achieve the above-mentioned purpose, the solution of the present utility model is: a motorcycle air filter, comprising a housing assembly, a filter element, a connecting pipe and an intake pipe;

[0006] A sealed air filter cavity is formed in the housing assembly;

[0007] The filter element is set in the housing assembly, dividing the inner cavity of the air filter into a primary chamber located on one side of the filter element and a secondary chamber located on the other side of the filter element. The gas in the primary chamber can only reach the secondary chamber after passing through the filter element;

[0008] One end of the connecting pipe is connected to the secondary chamber, and the other end is used to connect to the engine to intake air into the engine;

[0009] One end of the air inlet pipe is connected to the primary chamber, and the other end is exposed above the shell component to form an air inlet. The shell component is provided with a shielding portion that blocks the air inlet and forms an air gap between the shielding portion and the air inlet.

[0010] Furthermore, the shielding portion is groove-shaped on the top side of the shell component, has a notch facing one lateral side, and is closed in all directions except the notch. The air inlet pipe extends out of the top side of the shell component and protrudes within the groove-shaped shielding portion. The air inlet is opened on the portion of the air inlet pipe protruding within the shielding portion, and the direction of the air inlet is opposite to that of the notch.

[0011] Furthermore, the air inlet pipe extends to the middle of the primary chamber, and the air outlet end of the air inlet pipe faces the middle of the filter element.

[0012] Furthermore, the housing assembly forms a filter element mounting plate in the inner cavity of the air filter, and the filter element mounting plate is located between the primary chamber and the secondary chamber. A filter element mounting port is opened through the center of the filter element mounting plate. The primary chamber and the secondary chamber are connected only from the filter element mounting port. The filter element seal is installed on the filter element mounting port to separate the primary chamber and the secondary chamber.

[0013] Furthermore, a resonance cavity joint is formed in the middle of the connecting tube, and the resonance cavity joint is used to connect a resonance cavity so that the connecting tube is connected to the resonance cavity.

[0014] Furthermore, the housing assembly is formed by sealing and buckling a shell body and a shell cover, and the inner cavity of the air filter is located between the shell body and the shell cover.

[0015] Furthermore, the air intake pipe and the connecting pipe are made of rubber.

[0016] After adopting the above scheme, the beneficial effect of the utility model is that a closed air filter cavity is formed in the shell assembly, the filter element is arranged in the shell assembly, and the air filter cavity is divided into a primary chamber located on one side of the filter element and a secondary chamber located on the other side of the filter element. The gas in the primary chamber can reach the secondary chamber only after passing through the filter element and being filtered. One end of the connecting pipe is connected to the secondary chamber, and the other end is used to connect to the engine to intake air into the engine. One end of the intake pipe is connected to the primary chamber, and the other end is exposed to the shell assembly to form an air inlet. The shell assembly is provided with a shielding portion that blocks the outside of the air inlet and forms an air gap between the air inlet and the air inlet. Furthermore, there is no need to extend the intake pipe for a long length. The shielding portion is directly provided on the shell assembly to block the air inlet of the intake pipe to prevent the entry of rainwater and dust, so that an air gap is formed between the shielding portion and the air inlet, so that air can be stably fed into the intake pipe during use.
