Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.
As depicted in figs. 1 and 2, the first chamber 60, second chamber 50 and filter core 70 is comprised according to the air-strainer 100 of the utility model embodiment, described filter core 70 is connected between the first chamber 60 and the second chamber 50, to filter the air flowing to the second chamber 50 from the first chamber 60.First chamber 60 is used as upstream cavity, its wall offers the suction port 20 for connecting suction tude (not shown), second chamber 50 is used as downstream cavity, it has multiple wall, a wall offers the air outlet 10 for connecting steam outlet pipe (not shown) wherein, and for connecting the auxiliary air outlet 30 of auxiliary steam outlet pipe.Described steam outlet pipe is communicated with the suction port (not shown) of engine chamber, and described auxiliary steam outlet pipe is communicated with the crankcase (not shown) of air outlet motor.In the present embodiment, described auxiliary air outlet 30 is opened on the wall adjacent with the wall at place, described air outlet.But, should be appreciated that described auxiliary air outlet 30 also can be opened on the wall at place, described air outlet.
Particularly, when the pressure increase of the gas leakage in cylinder, blowby gas stream is back in the second chamber 50 of filter cleaner 100 by auxiliary air outlet 30, now, because auxiliary air outlet 30 is set to described air outlet 10 on same wall or adjacent wall, the two is very close each other, then reflux airflow can be easy to the air outlet 10 flowing into filter cleaner 100, thus discharges from the second chamber 50 in time.
As shown in Figure 2, in the present embodiment, described filter core 70 has the surface of general planar, and described filter core 70 is first surface towards the surface of described second chamber.
In the present embodiment, after described auxiliary air outlet 30 can be arranged so that described auxiliary steam outlet pipe is connected to described auxiliary air outlet 30, the air-flow being entered described second chamber 50 by auxiliary steam outlet pipe has the first flow direction, and described air outlet 10 is pointed in this first flow direction projection on the first surface.The setting of described auxiliary air outlet 30 comprises the aperture of described auxiliary air outlet 30, auxiliary air outlet 30 relative to the blowing angle of air outlet 10, level and vertical position etc.Preferably, described first flow direction is positioned at and connects described auxiliary air outlet 30 with on the straight line of the open centre of described air outlet 10, to make the flow path of air-flow in the second chamber 50 the shortest, thus discharged from the second chamber 50 by air outlet 10 with the fastest time.
According to a kind of mode of execution, the connection angle that described auxiliary steam outlet pipe is connected to described auxiliary air outlet 30 makes the flow direction being entered the air-flow of described second chamber by auxiliary steam outlet pipe not vertical with the cartridge surface that described filter core 70 is arranged in the second chamber 50.Preferably, the angle between the flow direction of described air-flow and described first surface is less than 30 degree.More preferably, the flow direction of described air-flow is parallel to described first surface.So, to reduce the chance of the Contact of reflux gas and filter core, alleviate the pollution of reflux airflow to filter core.According to another preferred implementation, described auxiliary air outlet 30 be arranged so that described auxiliary steam outlet pipe is connected to described auxiliary air outlet 30 after, the flow direction being entered the air-flow of described second chamber 50 by auxiliary steam outlet pipe is arranged in the direction skew of the filter core first surface of the second chamber 50 to deviating from described filter core 70, like this, reflux airflow is pushed to the second chamber 50 superjacent air space deviating from described first surface, and just air outlet 10 has been arrived when not yet near filter core 70, discharge from the second chamber 50.Which further improves the effect alleviating filter core and pollute.
In addition, in the embodiment of engine aspirating system applying above-mentioned air-strainer 100, described engine aspirating system (not shown) comprises cylinder, crankcase and air-strainer.Described air outlet 20 is communicated with the suction port of engine chamber by described steam outlet pipe.Described air-strainer 100 is connected to starter crankcase by auxiliary air outlet 30 and auxiliary steam outlet pipe.Described suction port connects admission line.Fresh air enters filter cleaner from the suction port 20 of filter cleaner 100, and from the suction port of the firing chamber the flow direction engine cylinder of described air outlet after described filter core 70 filters.
When the pressure increase of the gas leakage in cylinder, leak gas through crankcase, assist air outlet 30 to be back in filter cleaner 100.Due on the wall that auxiliary air outlet 30 is positioned at place, described air outlet 10 or on adjacent wall, near described air outlet 10, therefore, gas leakage is flowed out easily through air outlet 10, is entered engine chamber from air-strainer 100, and can not pollute the filter core 70 of air-strainer 100 and damage.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
