Abstract
The air filter switching air lane comprises a barrel, bottom plate at the bottom of the barrel opposite to the inlet, multi air breathers evenly spread at the side wall of the barrel, with the overall flow area of the air breathers bigger than that from the inlet of the barrel. By changing the direction of air flow and scattering it, the air filter switching air lane can improve the behavior of the filter element, extend durability, greatly increase the flow amount of pure gas, and effectively improve the power of the combustion engine.
Description
Technical field
The present invention relates to internal-combustion engine, is relevant with the empty filter of internal-combustion engine specifically.
Background technique
The empty filter of present internal-combustion engine, air is directly to enter sky filter housing inner chamber by suction port, by filter core air is carried out filtration, purification then.Because the direct subtend filter core of suction port, this structure make the air that enters by suction port can boundling rush at filter core and suction port over against the position, cause like this at this position dust ratio and be easier to pile up, make this place's dust stackeding speed faster than other positions, weakened to sucking the purification of air, caused the air inlet wretched insufficiency simultaneously, not only can influence engine operating condition, reduce power, and require to change the cycle shortening of cleaning filter core.
Summary of the invention
Pile up the problems referred to above that cause in the filter core concentration of local at the dust that existing empty filter intake method causes, the object of the present invention is to provide a kind of reversing air duct of air filter, can change the flow direction that enters the sky filter by this commutation air flue, improve the behaviour in service of filter core.In the structure that has installed the air pressurized air inlet additional, can avoid pressed gas directly to aim at the filter core of empty filter inner chamber effectively, avoid the local location of gas concentrations in filter core.
The present invention adopts following technical solution, a kind of reversing air duct of air filter, comprise a cylindrical shell, it is characterized in that: with inlet over against cylindrical shell bottom be provided with base plate, described base plate is imperforate plate or has the oblique exhaust port of discharge directions to the cylindrical shell periphery on described base plate, be evenly equipped with a plurality of vents on cylinder lateral wall, total circulation area of vent is greater than the circulation area of cylindrical shell inlet.
Vent on the described cylinder lateral wall can be the through hole of a plurality of circular holes or other shape.More satisfactory direction is that described vent is along the axial arranged slit of cylindrical shell, so that obtain bigger circulation area.Further be that this slit is to constitute along the gap of drum shaft between the commutation ventilation leaf that is provided with.The orientation of described commutation ventilation leaf both can for cylindrical shell radially, better mode is radially to be an acute angle angle with cylindrical shell, to form the rotation direction vent, makes that the air-flow through this commutation air flue becomes swirling eddy.Further be, the cross section of described ventilation leaf is an arc, to form better rotate effect.
Commutation air flue of the present invention can be attached to existing empty filter suction port place during use, place sky filter housing inner chamber to get final product.Because change has taken place through its outgassing direction behind this ventilation road in air, no longer direct subtend filter core, and make air become divergent state by the boundling state, therefore avoid air inlet directly to concentrate and impact the position of filter core over against suction port, thereby prevent that dust from concentrating on the somewhere accumulation of filter core, thereby can improve the applying working condition of filter core, prolong Acceptable life, make effective Purge gas throughput obtain bigger improvement, and then can improve power of IC engine effectively.This and this commutation air passage structure are simple, and the parts quality of fit is less demanding, are fit to produce in batches, and be easy to assembly.
Description of drawings
Fig. 1 is the structural representation of reversing air duct of air filter of the present invention.
Fig. 2 is the partial sectional view of reversing air duct of air filter.
Fig. 3 and Fig. 4 are the another kind of mode of execution partial sectional view of reversing air duct of air filter.
Embodiment
Below in conjunction with the drawings and specific embodiments commutation air flue of the present invention is described further, to help understanding content of the present invention.But commutation air flue of the present invention is not limited to this specific embodiment.
As depicted in figs. 1 and 2, reversing air duct of air filter, comprise a cylindrical shell 2, with inlet 3 over against cylindrical shell bottom with base plate 6 sealings of atresia, on cylinder lateral wall, be evenly equipped with a plurality of vents 4, total circulation area of vent 4 is greater than the circulation area of the inlet 3 of cylindrical shell, to guarantee can not increase air flow resistance.
As shown in Figure 2, vent 4 on the cylinder lateral wall is for along drum shaft to a plurality of cross sections that are provided with being the axial slits between the ventilation leaf 5 of arc, form the rotation direction air outlet channel, so that air can fast rotational when these arcuate slots, form atwirl air-flow, so that even to the filter core direction, mobile fast.
According to the needs that the commutation air flue is installed, inlet 3 one ends of cylindrical shell 2 are provided with the flange-like flange 1 to outer lug, and flange 1 is provided with mounting hole 7, so that the installing and fixing of reversing air duct of air filter.
According to the concrete condition of mounting point, cylindrical shell 2 promptly can be illustrated in figure 2 as cylinder, also can be that cross section is the cylindrical shell of regular polygon or other shape.
As shown in Figure 3, be with different among the embodiment 1, vent 4 for and cylindrical shell radially be slit between the flat board ventilation leaf 5 of an acute angle angle α, can form the rotation direction air outlet channel equally, the air-flow when making air outlet channel through this shape becomes swirling eddy.The rotate effect of this structure air-flow slightly is worse than arc air outlet channel shown in Figure 2.
Certainly, vent 4 can also be the uniform circular hole on the cylinder lateral wall or the hole of other shapes.
As shown in Figure 4, also can be provided with the oblique exhaust port 8 of discharge directions on the described base plate 6 towards the cylindrical shell periphery.Because tiltedly the ventilation area of exhaust port 8 is less than the total circulation area of the vent on the cylinder lateral wall and the air inlet area of inlet 3, so the air mass flow by oblique exhaust port 8 seldom, and do not blow to filter core owing to can directly not concentrating for inclined hole, therefore still can improve the applying working condition of filter core, prolong Acceptable life, make effective Purge gas throughput obtain bigger improvement, and then can improve power of IC engine effectively.
