Combined type air filter with efficient filtering structure

The combined type air filter of the efficient filtering structure at least comprises an air filter body, and a filter element assembly and a rotational flow assembly are arranged at the upper end and the lower end of an inner cavity of the air filter body respectively. An air outlet pointing to the filter element assembly and an air inlet pipe pointing to the rotational flow assembly are arranged at the upper end and the lower end of the air filter body respectively, the air flow direction sequentially flows from the air inlet pipe, the rotational flow assembly and the filter element assembly to the air outlet, and the air flow passes through the rotational flow assembly in the direction of first downward and then upward. According to the combined type air filter with the efficient filtering structure, large and small particles in air can be filtered thoroughly through multi-layer filtering, and the filtering effect is good. 本实用新型提供的一种高效过滤结构的复合式空气滤清器，至少包括空气滤清器本体，所述空气滤清器本体内腔的上端和下端分别设置有滤芯组件和旋流组件，且所述空气滤清器本体的上端和下
