Background of the invention:
[0002] Fans are commonly used appliances in homes and workplaces to provide comfort through air circulation. They play a crucial role in maintaining a pleasant indoor environment, especially during hot weather. Traditional fans often operate at fixed angles, limiting their ability to direct airflow effectively across different areas of a room. Users typically adjust these fans manually, which can be cumbersome and may not meet individual preferences for airflow direction.

[0003] Existing pedestal fans generally offer basic features such as adjustable height and single-angle oscillation, but many lack versatility in airflow customization. Users often find themselves needing to reposition the fan or adjust its settings frequently to achieve their desired airflow direction, resulting in inconvenience and reduced efficiency. The advent of technology has introduced more advanced fan designs, including those with remote controls and timers. However, these solutions still often fail to address the fundamental need for multi-angle adjustability in airflow. Many modern fans also rely on complicated mechanisms that can lead to mechanical failures over time, ultimately diminishing user satisfaction and safety.

[0004] Current market offerings also vary widely in terms of performance and energy efficiency. While some fans operate quietly and efficiently, others produce significant noise or consume excessive energy, creating a trade-off between comfort and energy costs. Moreover, many fans lack intuitive interfaces, making it difficult for users to quickly adjust settings based on their immediate comfort needs. As consumer demand for customizable and user-friendly air circulation solutions grows, there remains a significant gap in the market for a fan that combines advanced adjustability, energy efficiency, and ease of use.

The linear movement of the slider 134 converts into the angular movement of the crank member 128 upon actuation of the knob 142 by the user, thereby transmitting the angular movement to the elongated shaft 158 via the clamp member 156. The elongated shaft 158 transmits the angular movement from the crank member 128 to the extendable stand 104 via the linkage member 162, thereby oscillating the fan 100 at the oscillating angle accordingly the position of the slider 134 changed by the user.

[0068] According to another exemplary embodiment of the invention, FIG. 8 refers to a flowchart 800 of a method for operating the fan 100 with the multi-angle adjustable oscillation function.
