Abstract

The invention provides a combined air filter. The combined air filter comprises an upper shell, a lower shell, a filter element, a multi-hole plate and an adsorption layer. The upper shell and the lower shell are fixedly connected to form an airtight cavity, and the filter element is arranged in the airtight cavity. The multi-hole plate is arranged on the top of the upper shell so that a noise reduction cavity can be formed between the multi-hole plate and the top wall of the upper shell. The adsorption layer is arranged in the noise reduction cavity. By adopting the technical scheme, the problem that the space inside an engine cabin is limited, and consequently the noise reduction functional components are difficult to distribute is well solved, meanwhile, the hydrocarbon leakage problemunder the emission requirements in CN6 is also solved, two purposes are achieved at one stroke, and meanwhile, the combined air filter has the beneficial effects of being simple in structure, relatively low in process cost, good in manufacturability and durability, capable of saving energy, environment-friendly and the like. The invention further discloses a vehicle provided with the combined airfilter.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a composite air filter. The present invention also relates to a vehicle including the composite air filter. Background technique [0002] At present, the air filter has a structure designed to reduce noise, and another part is fixed by welding or other processes on the shell. This part has a porous structure designed for special acoustic purposes, making it It forms a cavity with the housing, and allows the airflow flowing through the air filter to enter and exit the cavity freely, such as the patent No. 201621307321.8 titled "Air Filter, Engine Intake System and Vehicle" , The air filter includes an air filter housing, an air filter inlet duct, an air filter outlet duct, a filter element and a hydrocarbon adsorption device. At present, the air filter also has a structural design of a hydrocarbon adsorption device. The hydrocarbon adsorption device is mostly paper or non-woven fabric...
