Description
Technical field
The utility model relates to automotive engine air intake system technical field, particularly relates to a kind of air-strainer.
Background technique
The effect of motor inlet and exhaust system is supply engine fresh air, and the waste gas after engine combustion is drained into air, general gas handling system mainly comprises air-strainer and air intake branch, the function of air-strainer is impurity in filtering air or dust, and the air-strainer used at present is not isolated filtered air, also there is the effect of abatement induction noise; In addition, consider that air must have certain flow velocity to improve the air inflow of motor in air inlet flow guide pipe, if noise is excessive, will ride quality be affected, but for controlling induction noise, air inlet flow guide pipe must have larger volume, so, usually can only air inlet flow guide pipe be done longer, but, longer air inlet flow guide pipe can occupy space more in engine compartment, and assembling is inconvenient.
Model utility content
The technical problems to be solved in the utility model there is provided a kind of can guarantee and filters the air-strainer that air inlet function can reduce again induction noise.
The technical solution of the utility model is as follows:
A kind of air-strainer, comprise housing, lid and filter core, described housing and lid are cavity structure, this housing and lid combine between the higher and lower levels, the first dividing plate is vertically provided with in described housing, housing is divided into the first cavity and the second cavity by described first dividing plate, vent is provided with in the bottom of described first dividing plate, described filter core is embedded in the first cavity admittedly, liner plate is embedded with in described second cavity, described liner plate is evenly provided with multiple through hole, is provided with air outlet in the side of described housing, described air outlet is connected through with the second cavity; Be provided with suction port in the side of corresponding first cavity of described lid, described suction port is connected through with the first cavity, is vertically provided with second partition in this lid, and the lower end surface of described second partition aligns with the upper-end surface of the first dividing plate and abuts.
Adopt above structure, the separation of described second partition to lid makes to form air-inlet cavity between filter core and the lid of corresponding position, pure qi (oxygen) chamber is formed between first cavity and filter core, air is through suction port arrival air-inlet cavity and through filter element filtering, air after filtration enters pure qi (oxygen) chamber downwards, enter in the second cavity through vent again, and have air outlet to discharge in feeding motor, because the air velocity of intakeport is very fast, add the abutting of the first dividing plate and second partition, first cavity and the second cavity are closed mutually, filtered air can not flow backwards, and can not mix with unfiltered air, improve the efficiency of air inlet purification, meanwhile, because intake velocity is very fast, noise of air will be larger, the liner plate with multiple through hole is embedded, when filtered air is through the second cavity, through the resonance effect of multiple through hole in the second cavity, noise of air will reduce greatly, and the working state of air-strainer will be more steady.
Taking space more in engine compartment to reduce, avoiding the interference with miscellaneous part simultaneously, as preferably, be also provided with the arc groove of one section of indent along the axis of housing in the outside of described housing.
In order to strengthen the anti-vibration intensity of housing and lid, reducing the noise produced in air flow process further, as preferably, being equipped with multiple reinforced block in the outer of described housing and lid.
In order to improve resistant to elevated temperatures performance, as preferably, described housing and lid are one-body molded by PPS material injection respectively.
Beneficial effect: the utility model makes air be entered by suction port, then discharges from air outlet through filtration and resonance effect, compact structure, and convenient installation, adds air inflow, reduce noise, applied widely.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model is by housing 1, the compositions such as lid 2 and filter core 3, described housing 1 and lid 2 are the integrated cavity structure of PPS material injection, this housing 1 and lid 2 combine between the higher and lower levels, also be provided with the arc groove of one section of indent along the axis of housing 1 in the outside of described housing 1, the first dividing plate 11 is vertically provided with in described housing 1, housing 1 is divided into the first cavity 12 and the second cavity 13 by described first dividing plate 11, vent 4 is provided with in the bottom of described first dividing plate 11, described filter core 3 is embedded in the first cavity 12 admittedly, liner plate 15 is embedded with in described second cavity 13, described liner plate 15 is evenly provided with multiple through hole, air outlet 14 is provided with in the side of described housing 1, described air outlet 14 is connected through with the second cavity 13.
Be provided with suction port 21 in the side of corresponding first cavity 12 of described lid 2, described suction port 21 is connected through with the first cavity, is vertically provided with second partition 22 in this lid 2, and the lower end surface of described second partition 22 aligns with the upper-end surface of the first dividing plate 11 and abuts.
Be equipped with multiple reinforced block 5 in the outer of described housing 1 and lid 2, described housing 1 and lid 2 are one-body molded by PPS material injection respectively.
Using method of the present utility model is as follows:
As shown in Figure 1, shown by arrow direction is assembly direction, the separation of described second partition 22 pairs of lids 2 makes to form air-inlet cavity between the lid 2 of filter core 3 and corresponding position, pure qi (oxygen) chamber is formed between first cavity 12 and filter core 3, air arrives air-inlet cavity through suction port 21 and filters through filter core 3, air after filtration enters pure qi (oxygen) chamber downwards, enter in the second cavity 13 through vent 4 again, and have air outlet 14 to discharge in feeding motor (sign), because the air velocity of suction port 21 is very fast, add the abutting of the first dividing plate 11 and second partition 22, first cavity 12 and the second cavity 13 are mutually closed after lid 1 and housing about 2 fasten, filtered air can not flow backwards, and can not mix with unfiltered air, improve the efficiency of air inlet purification, simultaneously, because intake velocity is very fast, noise of air will be larger, the liner plate 15 with multiple through hole is embedded in the second cavity 13, when filtered air is through the second cavity 13, through the resonance effect of multiple through hole, noise of air will reduce greatly, and the working state of air-strainer will be more steady.
When air-strainer works, the reinforced block 5 outside housing 1 and lid 2 can also help to reduce the vibrating noise that air flowing produces further.
It is consistent with prior art that the utility model does not describe part, and therefore not to repeat here.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model specification and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
