Anti-vortex structure for air inlet of fan

Abstract

The utility model discloses an anti-vortex structure for an air inlet of a fan. The anti-vortex structure comprises a shell, a motor is mounted in the machine shell and mounted in the machine shell through a mounting frame, fan blades are mounted at the front end of the motor, a damping ring is arranged at the front end of the machine shell, an air guide plate is mounted in the damping ring, and a filter screen is arranged at the front end of the machine shell. The filter screen is fixedly installed at the front end of the machine shell through bolts. In the flowing process, firstly, the air is filtered through the filter screen, the filtered air is guided by the air guide plate, so that the air flows straightly, cyclone is avoided during use, vibration generated during use of the air guide plate can be reduced through the arrangement of the damping ring, the phenomenon that the air guide plate is loosened during use is avoided, and the service life of the air guide plate is prolonged. When the damping ring is installed, the damping ring is installed in the machine shell, and meanwhile, the inserting strips are inserted into the inserting grooves to fix the damping ring.
