Particularly, described first filtering net is arranged with vent is concentric.
For ensureing filter effect, the two ends up and down of described first filtering net are all closed with the respective inner walls of depositing air cavity and are connected.
Further, described lower piston mechanism comprises and deposits air valve for shutoff vent, for to deposit air valve support upper movable sleeve, be socketed with upper movable sleeve bottom and with the lower limit ring of described valve body clamping, and be nested with upper movable sleeve in the middle part of cone-shaped spring, wherein, depositing air valve has elastomeric material to make; Described upper movable sleeve upper end is provided with a cambered outwards limited ring dais in footpath, and described cone-shaped spring is between this limited ring dais and lower limit ring.
More specifically, described first filtering net comprises its height and to mate with cover body internal height and be the cover supporter of shell-like, cover supporter side is paved with the strainer body of layout, and is arranged at the nonrigid connector of the upper and lower edges at two ends of cover supporter respectively.
In order to ensure overall turnover tolerance, the air flux of described first filtering net is not less than the air flux of the second filtering net.What deserves to be explained is, generally, the cross-sectional plane depositing air cavity is the cross-sectional plane being greater than free air diffuser, the filtration fraction area of described first filtering net is the filtration fraction area much larger than the second filtering net, so meet on the basis of above-mentioned requirements at its air flux of guarantee, the very small and dense collection that the mesh of the strainer body of the first filtering net can be arranged, thus can filter most small solid particles, effectively ensure that the cleanliness of the gas by vent, reduce wearing and tearing and the damage of depositing air valve, improve its service life.
In order to reduce the impact on suction quantity, increase filter effect, the tapered shape of described second filtering net when ensureing air inlet flux.
Compared with prior art, the utility model has following beneficial effect:
The utility model is for the situation that now automotive air intake environment is poor at present, existing automobile valve body is improved, by built-in multilayer filtering net design dexterously, inlet air filtration, purification is have effectively achieved when not changing valve volume and not affecting air flux, reduce the wearing and tearing and damage of depositing air valve, improve its service life, and the utility model design is ingenious, structure is simple, with low cost, easy to use, be convenient to produce and manufacture, be with a wide range of applications, be applicable to applying.
