Electric fan is one of the common household appliances in modern life, it has won the favor of the majority of users with its simple structure and efficient cooling effect. Despite the variety of shapes, the function is relatively consistent, mainly through rotating fan blades to flow air, thus bringing cool feelings.
The history of electric fans dates back to the 19th century and was originally driven by steam engines, but with the popularization of electricity, electric fans gradually replaced the early hand-cranked fans and became indispensable devices in home and office environments. Its working principle is relatively simple, the motor drives the fan blade to rotate, creating air flow, which in turn reduces the temperature of the surrounding environment.
When using an electric fan, people usually notice the main difference between it and air conditioning. While air conditioning can provide a relatively stable and significant cooling effect, electric fans are more economical and energy efficient. At the same time, electric fans can also promote the circulation of air to a certain extent, helping to maintain the freshness of indoor air, which is not achieved by air conditioning alone.
With the advancement of science and technology, the types of electric fans have become more abundant. In addition to the traditional vertical and benchtop fans, new products such as bladeless fans, suspended fans and smart fans have been introduced in recent years. These fans not only look more modern, but also have more practical features, such as timers, remote control, Wi-Fi connection, etc., so that users can more easily adjust the wind speed and use time.
