Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a bladeless fan with long-distance air delivery function. Background Technology

[0002] Bladeless fans, also known as air multipliers, are a relatively new product that has become a mainstay in many stores in recent years. Because they have no blades, they are less likely to accumulate dust or injure children, making them safer and eliminating the hassle of disassembly and cleaning. They work by drawing air in from the bottom and then expelling it through the fan's outlet, creating a continuous stream of cool air. Since there are no fan blades "cutting" the air, users do not experience intermittent impacts or wave-like stimulation, resulting in greater comfort.

[0003] However, existing bladeless fans suffer from uneven airflow, short air delivery distance, complex structure, difficult disassembly and assembly, and poor sealing. Furthermore, bladeless fans require a higher compression ratio to ensure airflow, resulting in greater overall noise compared to conventional fans. Most bladeless fans with oscillation functions on the market rely on Hall effect switches for detection and identification, which increases the cost of bladeless fans. Utility Model Content
