Problems solved by technology

[0003] The earliest ceiling fans used were controlled mechanically, with simple wind speed control, high noise, large changes in wind speed between various gears, and no automatic adjustment of temperature.
Due to its mechanical movement, the traditional electric fan affects people's normal rest when people are resting, and its timing range is also very short, so that people cannot meet their cooling needs

Abstract

The invention relates to an automatic temperature regulating fan. The automatic temperature regulating fan comprises a shaking head fan body and a control module. The control module comprises a temperature acquisition unit for detecting ambient temperature, a plurality of human infrared sensors installed on a base and corresponding to different induction areas, a fan motor driving unit for drivinga fan motor, a shaking head motor driving unit for driving a shaking head motor and a control unit, wherein the control unit receives a temperature signal detected by the temperature acquisition unitand controls the speed of the fan motor, and receives human body signals detected by the human body infrared sensors and controls the rotation angle of the shaking head motor. According to the automatic temperature regulating fan, the wind speed of the fan is controlled according to the ambient temperature, and the comfort of using the fan is improved; a human body is detected by the human infrared sensors, the fan is turned off when no one exists, when a person exists, the rotation angle of the shaking head motor is adjusted according to the position of the human body, the rotation of the fan in an invalid area is avoided, energy is saved, the heat dissipation speed is improved, and the experience degree of a user is improved.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an automatic temperature-regulating fan and a control method thereof. Background technique [0002] In modern life, with the popularization of air conditioners, the "air conditioner disease" followed. Although air conditioners are frequently used, the market for electric fans has not been affected. The advantage is that the electric fan speeds up the flow of air to achieve the purpose of heat dissipation. The electric fan is suitable for people of different ages, and the price of the electric fan is more acceptable, energy-saving and environmentally friendly, and easy to use and assemble. Therefore, electric fans are still the first choice for people's daily cooling tools. [0003] The earliest ceiling fans used were mechanically controlled, with simple wind speed control, high noise, large wind speed changes between gears, and no automatic temperature adjustment. Due to its mecha...
