Introduction
An electric fan is an essential appliance in most homes and offices. It helps to keep the air circulating and provides a cooling effect during hot weather. However, the design of electric fans has remained relatively unchanged for decades. In this paper, we propose a new design for an electric fan lifting spring that enhances the functionality of the appliance.
Background
Electric fans typically have a stand or base that supports the fan head. The stand is fixed in place, and the fan head can be adjusted up or down using a lifting spring. The lifting spring is usually located at the base of the fan head and provides tension to keep the fan head in place at the desired height.
However, the current design of the lifting spring has limitations. It can be difficult to adjust the height of the fan head to a precise level, and the fan head may slowly lower over time. Additionally, the tension in the lifting spring may weaken over time, reducing its effectiveness.
Proposed Design
Our proposed design for an electric fan lifting spring addresses these limitations. The new design incorporates a locking mechanism that allows the user to adjust the height of the fan head more precisely. The locking mechanism can be easily activated with a single hand, allowing the user to adjust the height of the fan head while holding it in place.
Additionally, the new design includes a spring tension adjustment feature. This allows the user to adjust the tension in the spring to their liking, ensuring that the fan head stays at the desired height. The tension adjustment feature is easily accessible and can be adjusted without the need for any special tools.
Conclusion
The proposed design for an electric fan lifting spring offers several advantages over the current design. The locking mechanism allows for more precise height adjustments, and the spring tension adjustment feature ensures that the fan head stays at the desired height. These enhancements can lead to a more functional and user-friendly electric fan.
