AI Technical Summary
Existing ceiling fan motors are noisy and susceptible to moisture damage. Turbulence created by the gap between the fan blades and the motor rotor increases resistance, affecting airflow efficiency and lifespan.
A novel ceiling fan structure was designed, including a fan mounting plate, a motor mounting mechanism, a protective sleeve, fan blades, and a fan blade mounting base. The motor is fixed inside the protective sleeve by connectors and fasteners. The lower end of the protective sleeve is hemispherical to reduce turbulence, enhance airflow concentration, and provide sealed moisture protection.
It effectively shields motor noise, reduces the impact of turbulence, improves airflow intensity and long-distance blowing effect, while protecting the motor from moisture damage and facilitating cleaning and maintenance.
