Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a floor fan. Background Technology

[0002] Currently, floor fans, as common air circulation devices, are widely used in homes, offices, and industrial environments. They primarily use a motor to drive the fan blades to rotate, generating airflow to achieve functions such as ventilation and cooling. As users' demands for product functionality and convenience increase, floor fans are continuously optimized in structural design to meet diverse usage needs.

[0003] Traditional floor fans typically consist of three main parts: the fan head, the support rod, and the base. These components are usually connected by fixed structures, such as welding or screws. While the structure is simple, it has several drawbacks in practical use. For example, the overall structure is difficult to disassemble, leading to inconvenient transportation, large storage space requirements, and cumbersome maintenance or replacement of parts, increasing repair costs.
