Description

Cleaning structure for air filter Technical Field The utility model relates to the technical field of filters, in particular to a cleaning structure for an air filter. Background The air filter is mainly used for filtering dust and impurities in air and providing clean air for an internal combustion engine so as to reduce the abrasion of the engine. Especially in working areas with serious dust such as construction sites and mines, the filter element in the air filter is blocked by accumulated dust in a short time, so that the air inlet resistance and the oil consumption of the engine are increased, and the power output of the engine is affected. The air cleaner is generally installed at the position of the air inlet of the engine compartment, and can ensure that air is efficiently filtered before entering the engine, thereby preventing impurities from entering the engine and protecting the engine from abrasion.
