Why does the fan have a oscillation function?

 Scientific Principle

1.Expand Airflow Coverage

The oscillation function periodically changes the horizontal or vertical angle of the fan head, allowing airflow to cover a wider area. According to fluid dynamics, a fixed airflow direction creates localized high wind speed (e.g., "wind column effect"), while oscillation disperses airflow energy for more uniform air disturbance.

2.Enhance Air Circulation

The oscillation mechanically accelerates indoor air convection. A stationary fan only pushes localized air, while dynamic airflow from oscillation breaks thermal stratification and mixes warm/cool air, improving overall cooling efficiency.

3.Prevent Physical Discomfort

Prolonged exposure to fixed airflow may trigger the wind chill effect, causing dry skin or muscle stiffness. Oscillation reduces continuous wind pressure via intermittent airflow, aligning with ergonomic comfort requirements.

Design Purpose

The oscillation function combines aerodynamics and human comfort needs to balance efficient cooling and user experience. Studies show that in oscillation mode, the perceived temperature can be 1-2°C lower than with fixed airflow, while reducing energy waste by over 30% (by avoiding maximum speed settings).

Additional Benefits

• Multi-scenario Adaptation: Oscillation angles can be adjusted (e.g., narrow for desks, wide for living rooms) to suit diverse spaces.

• Energy-saving Potential: Wide-area airflow reduces reliance on AC, indirectly lowering carbon emissions (MIT 2021 study).
