Description

Technical Field

[0001] The utility model relates to a fan, in particular to a multi-layer wind-gathering fan using a multi-slot single-phase motor. Background Art

[0002] One of the core goals of designing a home or commercial fan is to provide adequate cooling. To achieve this goal, fan designers usually focus on how to increase air volume and pressure. In traditional designs, fans usually use a single mesh cover and a simple blade structure to generate air flow. However, this design often leads to increased noise and energy consumption while further increasing air pressure and air volume.

[0003] In the home and commercial fan markets, consumers have different demands for air volume and air pressure. Some people prefer strong winds to feel an instant coolness on a hot summer day, while others prefer gentle winds to create a comfortable atmosphere. However, traditional fan designs have certain limitations in meeting these different demands. Utility Model Content
