Description

Air filter core with self-cleaning function Technical Field The utility model belongs to the field of air purification and filtration, and particularly relates to an air filter element with a self-cleaning function. Background The air filter element is a filter, also called an air filter cartridge, an air filter, a style, and the like. The engine is mainly used for filtering air in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operation chambers and various precise operation chambers, and a great amount of air is sucked into the engine in the working process, and if the air is not filtered, dust suspended in the air is sucked into the air cylinder, the abrasion of the piston group and the air cylinder can be accelerated. Larger particles enter between the piston and the cylinder, which can cause severe "scuffing" phenomena, which are particularly severe in dry sandy working environments. The air filter is arranged in front of the carburetor or the air inlet pipe, plays a role in filtering dust and sand in air, and ensures that sufficient and clean air enters the cylinder. Original air filter is in order to increase filtration area, and the increase is inhaled the amount of wind, and most be folding form, and folding apex angle department can cause to wrap up in and hold together, mix with some granule dust, causes the stifled hole, and the replacement cycle is short, and the replacement is with high costs, and still need pull down the dust removal with air filter in order to guarantee the filter effect in the replacement cycle, and complex operation and adoption air gun blows and can cause the damage to the filter core, and the impurity dust that the filter core surface was accumulated for a long time is more intractable. The common solution is to add a layer of first filter screen outside the filter core, and the net is too thin can influence the volume of absorbing air, and the net is too thick to have great dust and particulate matter to pass, can not reach and filter coarse particle effect. Disclosure of utility model In view of the above, the utility model aims to provide an air filter core with a self-cleaning function, so as to solve the problems that the folding vertex angle of the original air filter core can cause wrapping and mixing with some granular dust, thus causing hole blockage, the replacement period is short, the replacement cost is high, the air filter core is required to be removed for dust removal in order to ensure the filtering effect in the replacement period, the operation is complicated, the filter core is damaged by blowing by adopting an air gun, and the impurity dust accumulated on the surface of the filter core for a long time is more intractable. The common solution is to increase one deck first filter screen in the filter core outside, and the net is too thin can influence the volume of absorbing air, and the net is too thick has great dust and particulate matter to pass, can not reach the problem of filtering coarse particle effect.
