A self-adjusting electric fan

Abstract

The invention discloses an automatic regulation electric fan and belongs to the technical field of electric fans. The automatic regulation electric fan comprises a plurality of movable temperature and humidity assemblies which are uniformly distributed in a room where the electric fan is located and located in the front portion of the electric fan. The height of the movable temperature and humidity assemblies is consistent with the height of the center position of a blade disk. The included angle of every two adjacent movable temperature and humidity assemblies relative to the center of the blade disk is 30 degrees. A controller measures the distances between the blade disk and the movable temperature and humidity assemblies through an infrared distance measurement module. Position coordinates of the movable temperature and humidity assemblies with a stand column as the zero point of the coordinates are established. The movable temperature and humidity assemblies acquire temperature and humidity data through the infrared distance measurement module and a humidity module and transmit the temperature and humidity data to the controller. The controller controls a head swinging mechanism and a variable frequency motor according to the position coordinates and the temperature and humidity data. The automatic regulation electric fan can establish a measurement area for the movable temperature and humidity assemblies, automatically regulate air blowing and regulate the temperature and humidity of the measurement area by regulating the number of revolutions of the variable frequency motor and head swinging and rotating of the fan so as to bring a comfortable living area for people.

technical field [0001] The invention relates to the technical field of electric fans, in particular to an automatic regulating electric fan. Background technique [0002] With the development of science and technology and market economy, people's living standards have improved, and the performance of various electrical appliances has become higher and higher. A single performance can no longer meet people's needs. In daily life, electric fans are indispensable in summer. Electric appliances, a single cooling fan, can no longer be used in winter, which will cause idle resources. [0003] The electric fans on the market control the wind speed by grades. After the gear is set, it will be the same wind speed. If it is used in summer, the temperature will become lower on rainy nights, and the wind speed of the fan will not change.

Problems solved by technology

[0002] With the development of science and technology and market economy, people's living standards have improved, and the performance of various electrical appliances has become higher and higher. A single performance can no longer meet people's needs. In daily life, electric fans are indispensable in summer. Electric appliances, a single cooling fan, can no longer be used in winter, which will cause idle resources

[0003] The electric fans on the market control the wind speed by grades. After the gear is set, it will be the same wind speed. If it is used in summer, the temperature will become lower on rainy nights, and the wind speed of the fan will not change. Without a comfortable temperature that satisfies people’s normal work and rest, people are prone to being woken up from the cold during rest, which will cause people’s sleep quality to decline, which in turn will affect the work efficiency of the next day

[0004] The electric fans on the market do not have lights to see clearly. It will be inconvenient to operate the fan at night, and there may be operational errors. Since the fan uses 220V mains power, it may be hesitant to see it at night. Touching the socket and wire interface brings personal safety. Due to various inconveniences in use, these electric fans can no longer meet people's needs. Therefore, more intelligent, multi-functional, and safer electric fans are needed on the market.

[0005] To sum up, there is currently a lack of an automatic adjustable electric fan on the market that can meet people's use in all seasons, warm in winter and cool in summer, make full use of resources, do not need to set wind speed gears, intelligently adjust the wind speed, and meet the comfort temperature of people's work and rest needs. The lighting is bright, and the fan can be operated safely and conveniently without affecting people's work and rest. The fan really meets people's use in four seasons, automatically adjusts the wind speed, controls the temperature, has good vision, and is easy and safe to operate.
