AI Technical Summary
Technical Problem
In existing air purifiers, the V-shaped pleated structure of the air filter results in low airflow efficiency and high resistance, which affects the purification effect.
Method used
The air filter is designed with a trapezoidal raised pleated structure that is equidistantly arranged along a circular trajectory. This increases the included angle, reduces air resistance, and increases the contact area. Combined with steel wire, nylon filter and carbon filter, the filtration effect is enhanced.
Benefits of technology
It improves airflow and circulation efficiency, increases air volume, ensures filtration effect, and enhances the purifier's purification capacity.

Abstract
This utility model discloses an air purifier structure, relating to the field of air purifiers. It includes an air outlet hood and an air inlet hood fixedly connected from top to bottom. A pressure plate is fixed inside the air outlet hood, and a base is fixed inside the air inlet hood. A pre-filter with a ring-shaped structure is provided within the space between the pressure plate and the base. An air filter screen with an air distribution ring-shaped structure is provided inside the pre-filter. In this utility model, the air filter screen is folded to form multiple raised pleats equidistantly arranged along a circumferential trajectory. The raised pleats have a trapezoidal structure, which can enlarge the included angle portion of the pleats, thereby reducing the air resistance caused by the included angle portion. While increasing the contact area between the air and the mesh, it also reduces the resistance of air passing through the included angle portion of the pleats, thereby increasing the airflow that can pass through the included angle portion of the pleats, ensuring the filtration effect while improving the efficiency of air flow and circulation.
