Description
Technical field
The utility model, about a kind of air filtering device structure, is particularly applied to the air filtering device structure on automobile.
Background technique
Air filter filter assembly is the important component part of cargo vehicle gas handling system, is undertaking filtration dust and moisture in gas handling system, ensures the important function that engine charge is clean totally, humidity is suitable.
The light card of tradition uses air cleaner assy mostly to be dry type air filter, filter core in air filter is generally cylindric or planar, air filter assembly is without resonant cavity mechanism, although manufacture simple, but filter core assembly filter area is little, and intake resistance is large, hold ash amount little, simultaneously to gas handling system without sound deadening, NVH poor-performing.
When the work of conventional air filter cleaner, air is entered by suction port, air enters rear automatic filling in the cavity being always shaped as by housing assembly, filter core assembly and lower end cap, subsequently, air is due to the natural aspiration of motor, enter motor by directly flowing to air outlet after the filter paper on filter core, dust and impurity are left on paper, and air is cleaned.But due to circular filter core, area of contact is little, hold ash amount little, the very short time will be changed, and under simultaneously specific environment, the turnover of air easily produces noise.
In actual production process, find traditional air filter assembly, induction noise is large, on high-end truck, is more easily discovered, and travelling comfort is poor.Traditional air filter assembly simultaneously, intake resistance is large, holds ash amount little, uses the shorter time just to need to change, and cost is high.
In recent years, along with the development of automotive engineering, gently block market gas handling system noise and filter element life are had higher requirement, traditional air filter structure, can not meet present designing requirement

Alternatively, described annular filter path filter core is the track type filter core with straight line path part and circular arc path part.
Alternatively, described track type filter core comprises the frame of filter element of track type and the filter paper pallet of track type, and described filter paper pallet is fixed on described frame of filter element.
Alternatively, described track type filter core also comprises the filter paper being placed on described filter paper pallet, and described filter paper is corrugated folding layout continuously along described frame of filter element.
Alternatively, described filter core assembly is pressed abd fixed in described cavity by described housing assembly and described lower end cap assembly.
Alternatively, described housing assembly is connected by buckle with described lower end cap assembly.
Alternatively, described housing assembly also has the resonance chamber that described air is carried out to resonance.
Alternatively, described resonance chamber is positioned at upper half part or lower half portion of described housing assembly.
Alternatively, the outer end of described resonance chamber also has resonant cavity lid.
Alternatively, described resonance chamber and described resonant cavity lid are fixedly connected by welding.
Tabular or the cylindrical design of traditional filter core assembly is changed to annular by the utility model the technical program, and it increases the ash amount of holding, and solution intake resistance is large, filter core holds ash amount minor issue, can reduce replacing number of times, cost-saving.
