Abstract

The utility model provides a gradual sky filter of making an uproar that falls, including empty filter body, empty filter body is become with filter element group by the casing, and empty filter body upper end is equipped with the cap that admits air, the casing is toper structural design, the scale down sectional area that admits air, it upwards protruding and form spiral cavity from high in the inboard to low the extension to admit air the edge of cap, at the air inlet that is equipped with high -end outwardly directed relatively of spiral cavity, and middle the undercut of the cap that admits air and upwards stretch out in central authorities and be equipped with the gas outlet, the whole cap formation pre -flock device that admits air, filter core upper end is equipped with the blade ring, and the outside of blade ring is equipped with helical blade, and the cap that admits air during assembly lid makes it even as an organic whole with empty filter body on the blade ring top and at lower extreme and casing fixed connection, and the air flows into downwards from airflow channel during the use, filters back from gas outlet outflow through the filter core. This sky filter structure is small and exquisite, the manufacturing is convenient, and the air input is big, the resistance is little, has fully promoted the filtering quality of product, excellent in use effect.

Description

Gradual denoising air filter

Technical field

The utility model relates to technical field of automobile engine, particularly relates to a kind of gradual denoising air filter for motor.

Background technique

Air filter assembly is as the vitals of automobile, and it in use needs the coarse filtration efficiency and the charge flow rate that improve product, at utmost reduces the tail gas pollution and power loss that cause because engine combustion is insufficient, to realize the maximization of engine power.

But, tradition air filter inside adopts suction tude or tangent line air intake structure vertical with air filter body more, there is the abrupt change of cross-section in suction tude and body joint, and air filter interior layout space is often compact, do not have enough gas convolution spaces to go to ensure eddy flow trouble-free operation.Thus, when air-flow is by blade ring blade, easily produce the swirling eddy that liquidates, more disorderly, cause that intake resistance is relatively large, suction pressure increases, make pre-flock efficiency lower, be difficult to the requirement meeting the aspect such as engine energy-saving, noise reduction.

Summary of the invention

For improving filtering effect, effectively stoping air to form turbulent flow simultaneously, reducing noise during air filter work, the utility model proposes a kind of gradual denoising air filter for motor.

For this reason, the technical solution of the utility model is: gradual denoising air filter, comprise air filter body, air filter body is made up of housing and the filter core be arranged in housing, air filter body upper end is provided with air inlet cap, it is characterized in that: the tapered structural design of described housing, gradually reduces air inlet sectional area; The edge of described air inlet cap raises up and extends in inner side from high to low and forms spiral cavity, suction port is provided with the relatively high-end protruding of spiral cavity, the centre of air inlet cap protrudes upward to lower recess and in central authorities and is provided with air outlet, and whole air inlet cap forms pre-flock device; Described filter core upper end is provided with blade ring, the outside of blade ring is provided with screw blade, during assembling, air inlet cap covers on blade ring top and is fixedly connected with housing in lower end, air inlet cap and air filter body are connected as a single entity, during use, air flows into downwards from air-flow path, flows out after filter element filtering from air outlet.

Beneficial effect:

The utility model, by air filter housing is set to cone structure, gradually reduces air inlet sectional area, airintake direction is stablized, reduces turbulent flow, reduce induction noise; Device is considered in advance by arranging air inlet cap formation in body upper end; suction port is arranged on pre-worry device, removes suction tude from, improve process efficiency; reduce cost of production; adopt the design of rotary flow type air intake structure, reduce intake resistance, when ensureing to consider in advance, air-flow velocity does not subtract; effective prevention turbulent flow produces; ensure fine filtering eddy flow effect, protect filter core simultaneously, improve filtering effect.This air filter compact structure, easily manufactured, air inflow is large, resistance is little, fully improves the strainability of product, and using effect is good.
