AI Technical Summary
Existing indoor air purifiers have a single airflow direction, which cannot be quickly adjusted according to needs, affecting the diffusion effect of purified air.
A composite bag filter with an adjustable duct structure was designed. Through the combination of a guide plate, a rotating disk, and a drive component, the duct orientation can be flexibly adjusted, including the vertical angle adjustment of the arc-shaped duct and the angle adjustment of the rotating disk. Combined with a solenoid valve and hose connection, precise air delivery can be achieved.
It improves the diffusion efficiency and coverage of purified air, enabling the purified air to be delivered more accurately to the areas in need, thus enhancing the air purification effect.
