Description
Technical Field
The invention relates to an air filter for a vehicle.
Background
Vehicle air cleaners are located in the engine intake system and are assemblies of one or more air cleaner components. Its main function is to filter out harmful impurities in the air which will enter the cylinder, so as to reduce the early wear of the cylinder, piston ring, valve and valve seat. The original air inlet mode is that dirty air directly enters the air inlet of the lower shell of the air filter through the air inlet pipe, the airflow speed is stable due to the fact that the fan blades do not have the effect of rotating centrifugal force, air and dust can be directly pasted on the lower surface of the filter element of the air filter in a negative pressure adsorption state, resistance of the filter element of the air filter rises quickly, overall dust storage performance is reduced, and maintenance mileage of the whole vehicle is reduced.
The requirement on the ash storage capacity of the existing vehicle is higher and higher, particularly, the ash storage capacity of an off-road vehicle and the whole vehicle running in a desert and a dusty zone on a flat occasion is higher, the maintenance mileage and the maintenance time can be improved only by the high ash storage capacity, and the running mileage of the whole vehicle is improved.
Disclosure of Invention
In view of the above problems, the present invention aims to provide an air filter for a vehicle, which can improve the overall ash storage performance of the air filter on the premise of meeting the original performance requirement of the air filter.
The technical scheme includes that the air filter for the vehicle comprises an air filter lower shell, an air filter upper shell and an air filter element arranged between the air filter lower shell and the air filter upper shell, wherein the air filter upper shell is connected with an air outlet pipe, the air filter lower shell is provided with an air inlet end, the bottom of the air inlet end is provided with an ash discharge hole, the ash discharge hole penetrates through the bottom surface of the air filter lower shell, the lower surface of the air filter lower shell is provided with a connecting boss outside the ash discharge hole, the connecting boss is connected with an ash collection box, the bottom of the ash collection box is provided with a gap, the inner side surface of the air inlet end is provided with a limiting step, a positioning block is arranged on the limiting step, a fan with a plurality of spiral blades is installed on the limiting step, an air inlet pipe is arranged in an inner hole of an air inlet end, and the air inlet pipe is positioned and sealed and connected with the fan through sealing rubber.
Preferably, the dust collecting box is fixed on the connecting boss through a steel wire spring.
Preferably, the whole sealing rubber is circular ring-shaped, the tail end of the sealing rubber extends outwards to form a stopping part, the outer diameter of the stopping part is larger than that of the air inlet end, a series of outwards-protruding annular sealing ribs are arranged on the outer surface of the middle part of the sealing rubber, gaps are reserved between the adjacent annular sealing ribs, the outer diameter of each annular sealing rib is larger than the inner diameter of the air inlet end, and the front end of the sealing rubber is abutted to the rear side face of the fan to be limited.
Preferably, the width of the bottom gap of the dust collecting box is 0.3mm.
Preferably, the lower air filter shell is connected with the upper air filter shell through a metal draw hook after being assembled with the upper air filter element.
In the invention, air passes through the air inlet pipe to the fan, and the air and dust mixed in the air are influenced by the rotating centrifugal force when passing through the fan blades, the larger the weight of the dust particles is, the larger the inertia of the dust particles is, the larger the dust particles are, the dust particles can be separated from the main air inlet channel and directly fall into the dust discharge hole at the inner side of the fan opening, enter the dust collection box and fall through the gap at the bottom.
The invention improves the ash storage performance of the air filter, improves the ash storage amount of the air inlet system, improves the filtering precision of the air filter, and improves the running mileage of the whole vehicle and the maintenance period of the whole vehicle.
