Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle parts and components, in particular to an air filter intake pipe with an anti-drop structure. Background Art

[0002] Motorcycles use the combustion of a mixture of oil and gas to provide driving power. In order to prevent the inhalation of particulate impurities in the air from entering the combustion cylinder and affecting the normal operation of the engine, and even reducing the service life of the engine over time, it is necessary to install an air filter on the motorcycle to filter the air before supplying it to the engine for combustion.

[0003] A Chinese patent with a search publication number of CN214196509U discloses an air filter with a novel filter element, comprising a housing, a filter element assembly, an air inlet pipe and an exhaust pipe. The filter element assembly separates the inner cavity of the housing into a filter cavity and an exhaust cavity. The air inlet pipe is connected to the filter cavity, and the exhaust pipe is connected to the exhaust cavity. The filter element assembly comprises filter paper, a fireproof net, and a filter paper holder connected to the periphery of the fireproof net to wrap the filter paper. The two ends of the filter paper are relatively bent to form a package and arranged vertically. The filter paper holder abuts against the filter paper to form a filter cavity. The filter paper holder is provided with a connecting hole connected to the air inlet pipe. The vertically arranged filter paper can block dust after filtering air on the surface of the filter paper, and automatically fall from the surface of the filter paper under the action of the dust's own weight and the vibration of the internal combustion engine, thereby reducing the accumulation of dust on the surface of the filter paper and extending the service life of the filter element. At the same time, the two ends of the filter paper are relatively bent to form a package space, which can further increase the filtering area of ​​the filter paper and improve the filtering efficiency of the filter element.

[0004] However, the air filter intake pipe with the new filter element usually adopts an installation structure in which a compression spring is directly connected to the air filter. The intake pipe is mostly made of soft PVC material, and the intake pipe is often affected by vibration, high temperature and high cold environmental factors, and will become soft, hard or even cracked, thereby causing the air filter to fall off, causing the air filter to not work normally. Because the air filter needs to be cleaned and maintained frequently, a fixed, non-detachable installation structure cannot be used between the intake pipe and the air filter. Utility Model Content
