Description
Technical field
The utility model is related to a kind of filters, are specifically a kind of primary air filter.
Background technology
Air cleaner is mainly arranged in engine aspirating system, it is by the filter of one or several clean airs
Component composition assembly, main function be filter out will enter cylinder air in objectionable impurities, with reduce cylinder, piston,
The premature wear of piston ring, valve and valve seating.At present, in order to ensure engine have enough air inflows, existing automobile
Vehicles is waited generally all to be connected between the air inlet at air cleaner and vehicle motor room front end airflow grid with air entraining pipe
Logical, so in vehicle travel process, the air of outside vehicle can be just rapidly introduced into engine.But due to state
Internal region-by-region air quality causes anxiety, particularly the northern area of China, containing substantial amounts of dust, sand and dust in air, therefore works as vehicle
When the air of outside is entered directly by air entraining pipe in air cleaner, the work that will greatly increase air cleaner is born
Lotus so that the filter core of air cleaner is easily dirty, and it is dirty after filter core frequently can lead to engine charge deficiency, from
And make fuel oil incomplete combustion, engine job insecurity is in turn resulted in, engine is just present with power dropping, fuel consumption increases
The phenomenon that, therefore, in order to ensure that engine work, can only just replace the filter core of air cleaner, this not only considerably increases vehicle
Use cost, and undoubtedly greatly reduce the service life of air cleaner cartridge.
Utility model content
The technical problems to be solved in the utility model is to provide the larger ash contained by a kind of can filter out in air
The dirts such as dirt, sand and dust, so as to fulfill the preliminary filtering to air, and then the work that can substantially reduce rear class air cleaner is born
Lotus greatly prolongs the primary air filter of rear class air cleaner service life.
In order to solve the above technical problems, the utility model provides a kind of primary air filter with lower structure：Including
Housing, cap and the filter being arranged in housing cavity, cap are connected on housing, and housing is equipped with air inlet hole and outlet air
Hole, wherein, air inlet hole is located at below filter, and exhaust vent is located above filter, and filter includes box body and is filled in box body
Solid particle in inner cavity, the upper and lower wall of box body is net structure.
With the above structure, compared with prior art, the utility model has the following advantages：Since filter includes box
Body and the solid particle being filled in box cavity, the upper and lower wall of box body is net structure, therefore when air passes through filter
When, the dirts such as contained larger dust, sand and dust can be got off by the stop of solid particle in air, and air then can be from
It is passed through at gap between solid particle, so that the utility model primary air filter realizes the preliminary mistake to air
Filter, and then the live load of rear class air cleaner is greatly reduced, substantially prolong the service life of rear class air cleaner；
It jolts further, since vehicle can inevitably generate in the process of moving, therefore when the utility model primary air filter is with vehicle
It generates when jolting, the solid particle in box cavity can generate flowing and up-down vibration, can thus make most of by solid
The dirts such as dust, sand and dust that particulate blockage is got off are separated from solid particle, and fall on the bottom of box cavity, so as to have
Effect avoids the feelings that the dirts such as excessive dust, sand and dust are adsorbed on solid particle and the gap between solid particle is caused to be blocked by dirt
Condition occurs, and then the utility model primary air filter is enable to carry out prolonged lasting use, and is hindered by solid particle
