在过去，电器经常暴露出它们的缺点。电风扇作为一种家用电器，也存在着类似

In the past, electrical appliances often exposed their shortcomings. As a household appliance, electric fans also have similar problems. The main disadvantages of traditional electric fans are: <br>First: The wind speed cannot be adjusted automatically according to temperature changes. Each area has the same characteristics, and the temperature difference between day and night is often large, so the automatic adjustment of wind speed is particularly important, especially when people sleep, they often do not realize that night is a temperature change, wasting power resources, which is easy to cause cold. <br>Second: In order to reduce their own costs, traditional fans mostly use mechanical timing methods. Although mechanical timing is relatively inexpensive, it is often accompanied by a sound of dripping during work, especially at night. It has become more prominent, which greatly affects the quality of people ’s sleep at night. At the same time, mechanical timing is affected by the number of rotations. Timing time and volume have a great relationship. The longer the timing time, the larger the volume, and the cost will follow. The higher. <br>Third: The traditional fans are mainly manual operation, the main control method is analog control, the function is very single. <br>The fan plays an indispensable role in daily life. It is widely used in classrooms, student dormitories and supermarkets. Compared with the air conditioner, the fan has the characteristics of energy saving and free movement. During the operation of the fan, the natural wind blows out, so in the fundamental sense, it can effectively prevent the damage of the synthetic wind to the human body. At the same time, it has The advantages of light weight, simple use and low cost have always had a huge consumer group and broad development prospects. However, due to the shortcomings of traditional fans, consumers have limited choices when purchasing, and at the same time, they cannot meet people's needs in terms of safety, energy saving and automation. At the same time, with the continuous development of the Internet of Things technology and the continuous improvement of people's living standards, current household appliances are becoming more intelligent and humanized. As an important member of household appliances, fans must closely follow the development of the times and make their functions Richer and more humane.

In the past, electrical appliances often exposed their shortcomings. As a household appliance, electric fans have similar problems. The main disadvantages of conventional electric fans are:<br>First: the wind speed cannot be automatically adjusted according to the change of temperature. Each region has the same characteristics, often day and night temperature difference is relatively large, so automatic regulation of wind speed is particularly important, especially when people sleep, they often do not recognize the night is a temperature change, waste of power resources, easy to cause cold.<br>Second: the traditional fan in order to reduce their own costs, most of the use of mechanical timing, although the cost of mechanical timing is relatively low, but in the course of work, often accompanied by dripping sound, especially at night, this sound becomes particularly prominent, greatly affecting people's sleep quality at night, while mechanical timing is affected by the number of rotation softened, timing time and volume have a great relationship, the longer the timing time, the larger the volume, the higher the cost.<br>Third: the traditional fans are mainly manual operation, the main control means is analog control, the function is very single.<br>Fans play an essential role in daily life and are widely used in classrooms, student dormitories and supermarkets. Fan in contrast with air conditioning, with energy-saving, can move at will characteristics, fan work process, blowing out is natural wind, so in the fundamental sense, can effectively prevent synthetic wind damage to the human body, at the same time, it has the advantages of light volume, simple use and cheap, has always had a huge consumer group and broad prospects for development. However, due to the shortcomings of traditional fans, resulting in consumers to buy the limitations of choice, while in terms of safety, energy saving and automation can not meet people's needs for use. At the same time, with the continuous development of Internet of Things technology and people's living standards, now household appliances tend to be intelligent and humanized, fans as an important member of household appliances, but also to keep up with the pace of development of the times, so that its functions more rich, more humanized.
